Introduction
The Internal Revenue Bulletin is the authoritative instrument of
the Commissioner of Internal Revenue for announcing official
rulings and procedures of the Internal Revenue Service and for
publishing Treasury Decisions, Executive Orders, Tax Conven-
tions, legislation, court decisions, and other items of general
interest. It is published weekly and may be obtained from the
Superintendent of Documents on a subscription basis. Bulletin
contents are compiled semiannually into Cumulative Bulletins,
which are sold on a single-copy basis.
It is the policy of the Service to publish in the Bulletin all sub-
stantive rulings necessary to promote a uniform application of
the tax laws, including all rulings that supersede, revoke, mod-
ify, or amend any of those previously published in the Bulletin.
All published rulings apply retroactively unless otherwise indi-
cated. Procedures relating solely to matters of internal man-
agement are not published; however, statements of internal
practices and procedures that affect the rights and duties of
taxpayers are published.
Revenue rulings represent the conclusions of the Service on the
application of the law to the pivotal facts stated in the revenue
ruling. In those based on positions taken in rulings to taxpayers
or technical advice to Service field offices, identifying details
and information of a confidential nature are deleted to prevent
unwarranted invasions of privacy and to comply with statutory
requirements.
Rulings and procedures reported in the Bulletin do not have the
force and effect of Treasury Department Regulations, but they
may be used as precedents. Unpublished rulings will not be
relied on, used, or cited as precedents by Service personnel in
the disposition of other cases. In applying published rulings and
procedures, the effect of subsequent legislation, regulations,
court decisions, rulings, and procedures must be considered,
and Service personnel and others concerned are cautioned
against reaching the same conclusions in other cases unless
the facts and circumstances are substantially the same.
The Bulletin is divided into four parts as follows:
Part I.—19
86 Code.
This part i
ncludes rulings and decisions based on provisions of
the Intern
al Revenue Code of 1986.
Part II.—Treaties and Tax Legislation.
This part is divided into two subparts as follows: Subpart A,
Tax Conventions and Other Related Items, and Subpart B, Leg-
islation and Related Committee Reports.
Part III.—Administrative, Procedural, and Miscellaneous.
To the extent practicable, pertinent cross references to these
subjects are contained in the other Parts and Subparts. Also
included in this part are Bank Secrecy Act Administrative Rul-
ings. Bank Secrecy Act Administrative Rulings are issued by
the Department of the Treasury’s Office of the Assistant Sec-
retary (Enforcement).
Part IV
.—Items of General Interest.
This par
t includes notices of proposed rulemakings, disbar-
ment an
d suspension lists, and announcements.
The last Bulletin for each month includes a cumulative index
for the matters published during the preceding months. These
monthly indexes are cumulated on a semiannual basis, and are
published in the last Bulletin of each semiannual period.

ontents of this publication are not copyrighted and may be reprinted freely. A citation of the Internal Revenue Bulletin as the source would be appropriate.

SUPPLEMENTARY INFORMATION:
Background
On August 6, 2004, the IRS pub-
lished in theFederal Registeranoticeof
proposed rulemaking (REG–129771–04,
2004–2 C.B. 453) under section 951 of the
Code. Written comments were received
in response to the notice of proposed rule-
making. No public hearing was requested
or held on the notice of proposed rulemak-
ing. After consideration of the comments
received, the proposed regulations are
adopted as final regulations with the mod-
ifications discussed below. This issue
of the Bulletin also includes a notice of
proposed rulemaking (REG–129782–05)
setting forth specialpro ratashare rules
that apply to (1) a CFC with more than one
class of stock which has earnings and prof-
its and subpart F income for the taxable
year that are attributable to one or more
deemed dividends arising from one or
more transactions described in section 304
that are part of a plan a principal purpose
of which is the avoidance of Federal in-
come taxation, and (2) a CFC with certain
cumulative preferred stock outstanding
that is held by one or more persons who
are not U.S. taxpayers.
Summary of Public Comments and
Explanation of Changes
A.Amounts determined under section 956
of the Code.
Section 951(a)(1) requires a United
States shareholder of a CFC to include
in income the amount determined under
section 956 with respect to such share-
holder. The proposed regulations include
a conforming change to replaceincrease
in earnings invested in United States
propertywithamount determined under
section 956to reflect statutory changes
made to section 956 of the Code by the
Omnibus Budget Reconciliation Act of
1993, Public Law 103–66 (107 Stat. 312).
Commentators recommended that thepro
ratarules for section 956 be addressed in a
separate regulatory project because, after
the statutory change to section 956, the
section 951pro ratarules are no longer
relevant to a United States shareholder’s
inclusion of the amount determined under
section 956.
The IRS and Treasury Department
agree with this recommendation and ac-
cordingly have deleted all references to
section 956 under §1.951–(1)(e). Pro-
visions of §1.951–1(a) and (d) that con-
cerned a United States shareholder’spro
ratashare of the CFC’s increase in earn-
ings invested in United States property
have been revised and removed, respec-
tively, to conform the regulations to the
relevant post–1993 Code provisions. The
IRS and Treasury Department are con-
sidering a separate regulations project
regarding the amount determined under
section 956.
B.One class of stock - Proposed
§1.951–1(e)(2).
The proposed regulations state that if a
CFC for a taxable year has only one class
of stock outstanding, each United States
shareholder’spro ratashare of such cor-
poration’s subpart F income for the tax-
able year is determined by allocating the
CFC’s earnings and profits for such year
on a per-share basis. A commentator asked
that this rule be modified to clarify that the
relevant earnings and profits are earnings
and profits for such year unreduced by dis-
tributions during the year.
The IRS and Treasury Department
agree with the comment and have clarified
§1.951–1(e)(2) accordingly.
C.More than one class of stock —
Proposed §1.951–1(e)(3)(i).
In general, the proposed regulations al-
locate subpart F income among multiple
classes of stock by reference to the distri-
butions that would be made with respect to
each class if the CFC’s earnings and prof-
its for the year were distributed on the last
day of the CFC’s taxable year (the hypo-
thetical distribution). A commentator ex-
pressed concern that the hypothetical-dis-
tribution rule under the proposed regula-
tions could allocate earnings and profits to
preferred stock (including,e.g., preferred
stock with a noncumulative dividend pref-
erence) without regard to whether or when
dividends are or will be paid. The com-
mentator recommended that the proposed
regulations be amended to provide that
dividend rights should not be taken into ac-
count if, as of an appropriate date, the div-
idends have not been paid.
The IRS and Treasury Department have
considered this comment and have con-
cluded that, if the terms of a class of pre-
ferred stock are such that an obligation to
pay a dividend with respect to the stock
2005–40 I.R.B.614October 3, 2005

may or may not arise during the CFC’s
taxable year, depending on an exercise of
discretion by the CFC’s board of direc-
tors or a similar governing body, then the
stock should be considered to have discre-
tionary distribution rights. In such case,
the rule of §1.951–1(e)(3)(ii) would apply.
Therefore, the suggested amendment was
not adopted.
A commentator recommended that,
in the case of mandatorily redeemable
preferred stock with cumulative dividend
rights, the regulation should include an
anti-abuse rule to be applied where the
amount of earnings and profits required to
be allocated to such stock differs substan-
tially on a present-value basis from the
amount expected to be distributed on such
stock. Additionally, a commentator rec-
ommended that an anti-abuse rule could
target shareholder-level agreements that
are inconsistent with the economic terms
of the underlying stock.
The IRS and Treasury Department
agree that it is appropriate to provide a
special rule for theallocation of earn-
ings and profits to certain mandatorily
redeemable cumulative preferred stock
held by persons who are not U.S. taxpay-
ers. This special rule is set forth in a notice
of proposed rulemaking published in this
issue of the Bulletin (REG–129782–05).
With respect to the comments regarding
shareholder-level agreements, while the
proposed regulations are finalized without
modification in respect of that comment,
the IRS and Treasury Department may
issue regulations in the future if needed to
address those issues based on experience
following the publication of these regula-
tions.
D.Discretionary power to allocate
earnings to different classes of stock —
Proposed §1.951–1(e)(3)(ii)(A).
The proposed regulations provide that,
where the allocation of the amount of a
CFC’s earnings and profits for the taxable
year between two or more classes of stock
depends upon the exercise of discretion by
the board of directors or a similar govern-
ing body of the CFC, earnings and profits
shall be allocated to classes of shares with
discretionary distribution rights by refer-
ence to the relative values of those classes
at the time of the hypothetical distribution.
Commentators suggested that the use of a
value test could be complex, costly, and
time consuming. They proposed an alter-
native facts-and-circumstances test, with
the valuation approach being used as a fall
back only in limited situations. At the
same time, the commentators noted that
stock with discretionary distribution rights
generally does not appear to exist in the
marketplace (apart from ordinary common
stock).
The IRS and Treasury Department have
considered these comments and in light of
the latter comment do not believe that a
value-based allocation is likely to be re-
quired in many cases. The IRS and Trea-
sury Department are aware that valuation
is a sophisticated process but believe that
the interests of sound tax policy and ad-
ministration are served by requiring the
value-based allocation in those instances
covered by these regulations.
Under the proposed regulations, in
cases where the value of each of two or
more classes of stock with discretionary
distribution rights issubstantially the
same, the allocation of earnings and prof-
its to each such class is made as if such
classes constituted one class of stock. A
commentator suggested that values should
be treated assubstantially the samefor
this purpose if they are within a specified
percentage of one another.
The IRS and Treasury Department have
considered the comment and have con-
cluded that the existing language is suf-
ficient for the purposes of the regulations
without the need to adopt a specified per-
centage range. However,Example 3in the
regulations dealing with this issue has been
revised to indicate that values may be con-
sidered substantially the same even if the
difference between them is more thande
minimis.
E.Redemptions and scope of
deemed distributions — Proposed
§§1.951–1(e)(3)(ii)(B) and 1.951–1(e)(4).
The proposed regulations contain a spe-
cial rule that providesthat no amount shall
be considered to be distributed with re-
spect to a particular class of stock to the ex-
tent that such a distribution would consti-
tute a distribution in redemption of stock,
a distribution in liquidation, or a return of
capital. Commentators suggested that this
rule was too broad and that stock rights re-
sulting in deemed dividends under sections
302 or 305 of the Code should not be dis-
regarded in situations that are unlikely to
be abusive.
The IRS and Treasury Department have
considered the comments and have con-
cluded that no change is required. The
hypothetical distribution mandated by sec-
tion 951(a) of the Code contemplates apro
ratadistribution to shareholders with re-
spect to stock owned on the relevant date,
with no disposition of the stock or change
in stock rights being made at the same
time. Disregarding redemptions, liquida-
tions, or return of capital distributions for
this purpose serves the objectives of these
regulations without creating undue poten-
tial for unfairness or traps for the unwary.
A rule that provided that some deemed
dividends under sections 302 and 305 of
the Code are disregarded and some are re-
garded could be overly complex and diffi-
cult to administer.
The termdeemed distributionsin pro-
posed §1.951–1(e)(4) has been changed
tohypothetical distributionin order
to conform to the language used in
§1.951–1(e)(3).
F.Dividend arrearages — Proposed
§1.951–1(e)(3)(iv).
The proposed regulations retained the
rule in existing regulations with respect
to arrearages in dividends with respect to
classes of preferred stock of a CFC. Specif-
ically, the earnings and profits of the CFC
for the taxable year are attributable to such
arrearage only to the extent the arrearage
exceeds the earnings and profits remaining
from prior taxable years beginning after
December 31, 1962. Commentators sug-
gested that this rule can lead to anomalous
results, particularly where cumulative pre-
ferred stock is issued when a CFC has ac-
cumulated earnings and profits. In such a
case, a failure to pay dividends for some
number of periods could cause the pre-
ferred stock to attract earnings and prof-
its (and thus subpart F income) accumu-
lated prior to the issuance of the preferred
stock and thus fail to attract an appropri-
ate share of the CFC’s subpart F income.
Commentators suggested that this could be
addressed by allocating to dividend arrear-
ages only earnings and profits that arise af-
ter the issuance of the preferred stock.
The IRS and Treasury Department have
considered these comments and believe
October 3, 20056152005–40 I.R.B.

that such a rule is appropriate. The final
regulations adopt such a rule.
G.Section 958 of the Code.
Commentators suggested that a sepa-
rate project was needed to address the rela-
tionship between the indirect stock owner-
ship rules and thepro ratashare inclusion
rules.
The IRS and Treasury Department have
considered the comment. The need for
a separate regulations project of the kind
suggested may be considered at a later
date.
H.Effective date.
The proposed regulations were pro-
posed to apply for taxable years of a CFC
beginning on or after January 1, 2005.
Commentators recommended that the reg-
ulations provide transitional effective-date
guidance to taxpayers that may need to
take into account backward-looking provi-
sions of the Code or regulations regarding
the allocation of earnings and profits to
stock of a CFC.
The IRS and Treasury Department
have considered the comment and have
provided a transitional effective date rule
for cases in which the application of these
pro ratarules for purposes of applying a
related Code section, such as section 1248
of the Code, would result in an allocation
to the stock of the CFC of earnings and
profits that have already been allocated to
the stock for an earlier year under the prior
rules of §1.951–1(e). In that case, the prior
rules will continue to apply for purposes
of applying the related Code section.
Special Analyses
It has been determined that this Trea-
sury decision is not a significant regula-
tory action as defined in Executive Order
12866. Therefore, a regulatory assessment
is not required. It has also been deter-
mined that section 553(b) of the Admin-
istrative Procedure Act (5 U.S.C. chapter
5) does not apply to these regulations, and
because the regulations do not impose a
collection of information on small entities,
the Regulatory Flexibility Act (5 U.S.C.
chapter 6) does not apply. Pursuant to sec-
tion 7805(f) of the Code, the notice of pro-
posed rulemaking preceding these regula-
tions was submitted to the Chief Counsel
for Advocacy of the Small Business Ad-
ministration for comment on its impact on
small business.
Drafting Information
The principal author of these regula-
tions is Jeffrey Vinnik, Office of Associate
Chief Counsel (International). However,
other personnel from the IRS and Treasury
Department participated in their develop-
ment.

Adoption of Amendments to the
Regulations
Accordingly, 26 CFR part 1 is amended
as follows:
PART 1—INCOME TAXES
Paragraph 1. The authority citation for
part 1 continues to read, in part, as follows:
Authority: 26 U.S.C. 7805 * * *
Par. 2. Section 1.951–1 is amended as
follows:
1. Revising paragraphs (a)(2)(i) and
(a)(2)(iv).
2. Removing and reserving paragraph
(d).
3. Revising paragraph (e), and reserv-
ing paragraphs (e)(3)(v), (e)(4)(ii) and
(e)(6)Example 9.
The revisions read as follows:
§1.951–1 Amounts included in gross
income of United States shareholders.
(a) * * *
(2) * * *
(i) Such shareholder’spro ratashare
(determined under paragraph (b) of this
section) of the corporation’s subpart F in-
come (as defined in section 952) for such
taxable year of the corporation,
*****
(iv) The amount determined under sec-
tion 956 with respect to such shareholder
for such taxable year of the corporation
(but only to the extent not excluded from
gross income under section 959(a)(2)).
*****
(d) [Reserved].
(e)Pro rata share defined—(1)In
general. For purposes of paragraphs (b)
and (c) of this section, a United States
shareholder’spro ratashare of the con-
trolled foreign corporation’s subpart F
income, previously excluded subpart F
income withdrawn from investment in
less developed countries, or previously
excluded subpart F income withdrawn
from investment in foreign base company
shipping operations, respectively, for any
taxable year is hispro ratashare deter-
mined under §1.952–1(a), §1.955–1(c), or
§1.955A–1(c), respectively.
(2)One class of stock. If a controlled
foreign corporation for a taxable year has
only one class of stock outstanding, each
United States shareholder’spro ratashare
of such corporation’s subpart F income or
withdrawal for the taxable year under para-
graph (e)(1) of this section shall be deter-
mined by allocating the controlled foreign
corporation’s earnings and profits on a per
share basis.
(3)More than one class of stock—(i)In
general. Subject to paragraphs (e)(3)(ii)
through (e)(3)(v) of this section, if a con-
trolled foreign corporation for a taxable
year has more than one class of stock out-
standing, the amount of such corporation’s
subpart F income or withdrawal for the
taxable year taken into account with re-
spect to any one class of stock for purposes
of paragraph (e)(1) of this section shall be
that amount which bears the same ratio to
the total of such subpart F income or with-
drawal for such year as the earnings and
profits which would be distributed with re-
spect to such class of stock if all earnings
and profits of such corporation for such
year (not reduced by actual distributions
during the year) were distributed on the
last day of such corporation’s taxable year
on which such corporation is a controlled
foreign corporation (the hypothetical dis-
tribution date), bear to the total earnings
and profits of such corporation for such
taxable year.
(ii)Discretionary power to allocate
earnings to different classes of stock—(A)
In general. Subject to paragraph (e)(3)(iii)
of this section, the rules of this paragraph
apply for purposes of paragraph (e)(1) of
this section if the allocation of a controlled
foreign corporation’s earnings and profits
for the taxable year between two or more
classes of stock depends upon the exer-
cise of discretion by that body of persons
which exercises with respect to such cor-
poration the powers ordinarily exercised
by the board of directors of a domestic
corporation (discretionary distribution
rights). First, the earnings and profits of
2005–40 I.R.B.616October 3, 2005

the corporation are allocated under para-
graph (e)(3)(i) of this section to any class
or classes of stock with non-discretionary
distribution rights (e.g., preferred stock
entitled to a fixed return). Second, the
amount of earnings and profits allocated
to a class of stock with discretionary dis-
tribution rights shall be that amount which
bears the same ratio to the remaining earn-
ings and profits of such corporation for
such taxable year as the value of all shares
of such class of stock, determined on the
hypothetical distribution date, bears to
the total value of all shares of all classes
of stock with discretionary distribution
rights of such corporation, determined on
the hypothetical distribution date. For
purposes of the preceding sentence, in
the case where the value of each share of
two or more classes of stock with discre-
tionary distribution rights is substantially
the same on the hypothetical distribution
date, the allocation of earnings and profits
to such classes shall be made as if such
classes constituted one class of stock in
which each share has the same rights to
dividends as any other share.
(B)Special rule for redemption rights.
For purposes of paragraph (e)(3)(ii)(A)
of this section, discretionary distribution
rights do not include rights to redeem
shares of a class of stock (even if such
redemption would be treated as a distri-
bution of property to which section 301
applies pursuant to section 302(d)).
(iii)Special allocation rule for stock
with mixed distribution rights. For pur-
poses of paragraphs (e)(3)(i) and (e)(3)(ii)
of this section, in the case of a class of
stock with both discretionary and non-dis-
cretionary distribution rights, earnings and
profits shall be allocated to the non-discre-
tionary distribution rights under paragraph
(e)(3)(i) of this section and to the discre-
tionary distribution rights under paragraph
(e)(3)(ii) of this section. In such a case,
paragraph (e)(3)(ii) of this section will be
appliedsuchthatthevalueusedinthera-
tio will be the value of such class of stock
solely attributable to the discretionary dis-
tribution rights of such class of stock.
(iv)Dividend arrearages. For purposes
of paragraph (e)(3)(i) of this section, if
an arrearage in dividends for prior taxable
years exists with respect to a class of pre-
ferred stock of such corporation, the earn-
ings and profits for the taxable year shall
be attributed to such arrearage only to the
extent such arrearage exceeds the earnings
and profits of such corporation remaining
from prior taxable years beginning after
December 31, 1962, or the date on which
such stock was issued, whichever is later.
(v)Earnings and profits attributable
to certain section 304 transactions.[Re-
served].
(4)Scope of hypothetical distribu-
tion—(i)Redemption rights. Notwith-
standing the terms of any class of stock of
the controlled foreign corporation or any
agreement or arrangement with respect
thereto, no amount shall be considered to
be distributed as part of the hypothetical
distribution with respect to a particular
class of stock for purposes of paragraph
(e)(3) of this section to the extent that a dis-
tribution of such amount would constitute
a distribution in redemption of stock (even
if such redemption would be treated as a
distributionofpropertytowhichsection
301 applies pursuant to section 302(d)), a
distribution in liquidation, or a return of
capital.
(ii)Certain cumulative preferred stock.
[Reserved].
(5)Restrictions or other limitations on
distributions—(i)In general.Arestric-
tion or other limitation on distributions of
earnings and profits by a controlled for-
eign corporation will not be taken into ac-
count, for purposes of this section, in deter-
mining the amount of earnings and profits
that shall be allocated to a class of stock
of the controlled foreign corporation or the
amount of the United States shareholder’s
pro ratashare of the controlled foreign cor-
poration’s subpart F income or withdrawal
for the taxable year.
(ii)Definition. For purposes of this sec-
tion, arestriction or other limitation on
distributionsincludes any limitation that
has the effect of limiting the allocation or
distribution of earnings and profits by a
controlled foreign corporation to a United
States shareholder, other than currency or
other restrictions or limitations imposed
under the laws of any foreign country as
provided in section 964(b).
(iii)Exception for certain preferred dis-
tributions. The right to receive periodi-
cally a fixed amount (whether determined
by a percentage of par value, a reference
to a floating coupon rate, a stated return
expressed in terms of a certain amount of
dollars or foreign currency, or otherwise)
with respect to a class of stock the distri-
bution of which is a condition precedent to
a further distribution of earnings or prof-
its that year with respect to any class of
stock (not including a distribution in par-
tial or complete liquidation) is not a restric-
tion or other limitation on the distribution
of earnings and profits by a controlled for-
eign corporation under paragraph (e)(5) of
this section.
(iv)Illustrative list of restrictions and
limitations. Except as provided in para-
graph (e)(5)(iii) of this section, restric-
tions or other limitations on distributions
include, but are not limited to—
(A) An arrangement that restricts the
ability of the controlled foreign corpora-
tion to pay dividends on a class of shares
of the corporation owned by United States
shareholders until a condition or condi-
tions are satisfied (e.g., until another class
of stock is redeemed);
(B) A loan agreement entered into by
a controlled foreign corporation that re-
stricts or otherwise affects the ability to
make distributions on its stock until certain
requirements are satisfied; or
(C) An arrangement that conditions the
ability of the controlled foreign corpora-
tion to pay dividends to its shareholders
on the financial condition of the controlled
foreign corporation.
(6)Examples. The application of this
section may be illustrated by the following
examples:
Example 1.(i)Facts. FC1, a controlled foreign
corporation within the meaning of section 957(a), has
outstanding 100 shares of one class of stock. Corp
E, a domestic corporation and a United States share-
holder of FC1, within the meaning of section 951(b),
owns 60 shares. Corp H, a domestic corporation and
a United States shareholder of FC1, within the mean-
ing of section 951(b), owns 40 shares. FC1, Corp E,
and Corp H each use the calendar year as a taxable
year. Corp E and Corp H are shareholders of FC1 for
its entire 2005 taxable year. For 2005, FC1 has $100x
of earnings and profits, and income of $100x with re-
spect to which amounts are required to be included
in gross income of United States shareholders under
section 951(a). FC1 makes no distributions during
that year.
(ii)Analysis. FC1 has one class of stock. There-
fore, under paragraph (e)(2) of this section, FC1’s
earnings and profits are allocated on a per share basis.
Accordingly, for the taxable year 2005, Corp E’spro
ratashare of FC1’s subpart F income is $60x (60/100
x $100x) and Corp H’spro ratashare of FC1’s sub-
part F income is $40x (40/100 x $100x).
Example 2.(i)Facts. FC2, a controlled foreign
corporation within the meaning of section 957(a),
has outstanding 70 shares of common stock and 30
shares of 4-percent, nonparticipating, voting, pre-
ferred stock with a par value of $10x per share. The
October 3, 20056172005–40 I.R.B.

common shareholders are entitled to dividends when
declared by the board of directors of FC2. Corp A, a
domestic corporation and a United States shareholder
of FC2, within the meaning of section 951(b), owns
all of the common shares. Individual B, a foreign
individual, owns all of the preferred shares. FC2 and
Corp A each use the calendar year as a taxable year.
Corp A and Individual B are shareholders of FC2 for
its entire 2005 taxable year. For 2005, FC2 has $50x
of earnings and profits, and income of $50x with
respect to which amounts are required to be included
in gross income of United States shareholders under
section 951(a). In 2005, FC2 distributes as a dividend
$12x to Individual B with respect to Individual B’s
preferred shares. FC2 makes no other distributions
during that year.
(ii)Analysis. FC2 has two classes of stock, and
there are no restrictions or other limitations on distri-
butions within the meaning of paragraph (e)(5) of this
section. If the total $50x of earnings were distributed
on December 31, 2005, $12x would be distributed
with respect to Individual B’s preferred shares and the
remainder, $38x, would be distributed with respect to
Corp A’s common shares. Accordingly, under para-
graph (e)(3)(i) of this section, Corp A’spro ratashare
of FC1’s subpart F income is $38x for taxable year
2005.
Example 3.(i)Facts. The facts are the same as
inExample 2, except that the shares owned by Indi-
vidual B are Class B common shares and the shares
owned by Corp A are Class A common shares and the
board of directors of FC2 may declare dividends with
respect to one class of stock without declaring divi-
dends with respect to the other class of stock. The
value of the Class A common shares on the last day
of FC2’s 2005 taxable year is $680x and the value
of the Class B common shares on that date is $300x.
The board of directors of FC2 determines that FC2
will not make any distributions in 2005 with respect
to the Class A and B common shares of FC2.
(ii)Analysis. The allocation of FC2’s earnings
and profits between its Class A and Class B common
shares depends solely on the exercise of discretion by
the board of directors of FC2. Therefore, under para-
graph (e)(3)(ii)(A) of this section, the allocation of
earnings and profits between the Class A and Class
B common shares will depend on the value of each
class of stock on the last day of the controlled for-
eign corporation’s taxable year. On the last day of
FC2’s taxable year 2005, the Class A common shares
had a value of $9.30x/share and the Class B common
shares had a value of $10x/share. Because each share
of the Class A and Class B common stock of FC2 has
substantially the same value on the last day of FC2’s
taxable year, under paragraph (e)(3)(ii)(A) of this sec-
tion, for purposes of allocating the earnings and prof-
its of FC2, the Class A and Class B common shares
will be treated as one class of stock. Accordingly, for
FC2’s taxable year 2005, the earnings and profits of
FC2 are allocated $35x (70/100 x $50x) to the Class
A common shares and $15x (30/100 x $50x) to the
Class B common shares. For its taxable year 2005,
Corp A’spro ratashare of FC2’s subpart F income
will be $35x.
Example 4.(i)Facts. FC3, a controlled foreign
corporation within the meaning of section 957(a), has
outstanding 100 shares of Class A common stock,
100 shares of Class B common stock and 10 shares
of 5-percent nonparticipating, voting preferred stock
with a par value of $50x per share. The value of the
Class A shares on the last day of FC3’s 2005 taxable
year is $800x. The value of the Class B shares on
that date is $200x. The Class A and Class B share-
holders each are entitled to dividends when declared
by the board of directors of FC3, and the board of
directors of FC3 may declare dividends with respect
to one class of stock without declaring dividends with
respect to the other class of stock. Corp D, a domestic
corporation and a United States shareholder of FC3,
within the meaning of section 951(b), owns all of the
Class A shares. Corp N, a domestic corporation and
a United States shareholder of FC3, within the mean-
ing of section 951(b), owns all of the Class B shares.
Corp S, a domestic corporation and a United States
shareholder of FC3, within the meaning of section
951(b), owns all of the preferred shares. FC3, Corp
D, Corp N, and Corp S each use the calendar year as a
taxable year. Corp D, Corp N, and Corp S are share-
holders of FC3 for all of 2005. For 2005, FC3 has
$100x of earnings and profits, and income of $100x
with respect to which amounts are required to be in-
cluded in gross income of United States shareholders
under section 951(a). In 2005, FC3 distributes as a
dividend $25x to Corp S with respect to the preferred
shares. The board of directors of FC3 determines that
FC3 will make no other distributions during that year.
(ii)Analysis. The distribution rights of the pre-
ferred shares are not a restriction or other limitation
within the meaning of paragraph (e)(5) of this section.
Pursuant to paragraph (e)(3)(i) of this section, if the
total $100x of earnings were distributed on Decem-
ber 31, 2005, $25x would be distributed with respect
to Corp S’s preferred shares and the remainder, $75x
would be distributed with respect to Corp D’s Class
A shares and Corp N’s Class B shares. The allocation
of that $75x between its Class A and Class B shares
depends solely on the exercise of discretion by the
board of directors of FC3. The value of the Class A
shares ($8x/share) and the value of the Class B shares
($2x/share) are not substantially the same on the last
day of FC3’s taxable year 2005. Therefore for FC3’s
taxable year 2005, under paragraph (e)(3)(ii)(A) of
this section, the earnings and profits of FC3 are al-
located $60x ($800/$1,000 x $75x) to the Class A
shares and $15x ($200/$1,000 x $75x) to the Class B
shares. For the 2005 taxable year, Corp D’spro rata
share of FC3’s subpart F income will be $60x, Corp
N’spro ratashare of FC3’s subpart F income will be
$15x and Corp S’spro ratashare of FC3’s subpart F
income will be $25x.
Example 5.(i)Facts. FC4, a controlled foreign
corporation within the meaning of section 957(a), has
outstanding 40 shares of participating, voting, pre-
ferred stock and 200 shares of common stock. The
owner of a share of preferred stock is entitled to an an-
nual dividend equal to 0.5-percent of FC4’s retained
earnings for the taxable year and also is entitled to
additional dividends when declared by the board of
directors of FC4. The common shareholders are en-
titled to dividends when declared by the board of di-
rectors of FC4. The board of directors of FC4 has
discretion to pay dividends to the participating por-
tion of the preferred shares (after the payment of the
preference) and the common shares. The value of the
preferred shares on the last day of FC4’s 2005 taxable
year is $600x ($100x of this value is attributable to the
discretionary distribution rights of these shares) and
the value of the common shares on that date is $400x.
Corp E, a domestic corporation and United States
shareholder of FC4, within the meaning of section
951(b), owns all of the preferred shares. FC5, a for-
eign corporation that is not a controlled foreign cor-
poration within the meaning of section 957(a), owns
all of the common shares. FC4 and Corp E each use
the calendar year as a taxable year. Corp E and FC5
are shareholders of FC4 for all of 2005. For 2005,
FC4 has $100x of earnings and profits, and income
of $100x with respect to which amounts are required
to be included in gross income of United States share-
holders under section 951(a). In 2005, FC4’s retained
earnings are equal to its earnings and profits. FC4 dis-
tributes as a dividend $20x to Corp E that year with
respect to Corp E’s preferred shares. The board of
directors of FC4 determines that FC4 will not make
any other distributions during that year.
(ii)Analysis. The non-discretionary distribution
rights of the preferred shares are not a restriction
or other limitation within the meaning of paragraph
(e)(5) of this section. The allocation of FC4’s earn-
ings and profits between its preferred shares and
common shares depends, in part, on the exercise of
discretion by the board of directors of FC4 because
the preferred shares are shares with both discre-
tionary distribution rights and non-discretionary
distribution rights. Paragraph (e)(3)(i) of this sec-
tion is applied first to determine the allocation of
earnings and profits of FC4 to the non-discretionary
distribution rights of the preferred shares. If the total
$100x of earnings were distributed on December
31, 2005, $20x would be distributed with respect to
the non-discretionary distribution rights of Corp E’s
preferred shares. Accordingly, $20x would be allo-
cated to such shares under paragraphs (e)(3)(i) and
(iii) of this section. The remainder, $80x, would be
allocated under paragraph (e)(3)(ii)(A) and (e)(3)(iii)
of this section between the preferred and common
shareholders by reference to the value of the dis-
cretionary distribution rights of the preferred shares
and the value of the common shares. Therefore, the
remaining $80x of earnings and profits of FC4 are
allocated $16x ($100x/$500x x $80x) to the preferred
shares and $64x ($400x/$500x x $80) to the common
shares. For its taxable year 2005, Corp E’spro rata
share of FC4’s subpart F income will be $36x ($20x
+ $16x).
Example 6.(i)Facts. FC6, a controlled foreign
corporation within the meaning of section 957(a),
has outstanding 10 shares of common stock and 400
shares of 2-percent nonparticipating, voting, pre-
ferred stock with a par value of $1x per share. The
common shareholders are entitled to dividends when
declared by the board of directors of FC6. Corp M, a
domestic corporation and a United States shareholder
of FC6, within the meaning of section 951(b), owns
all of the common shares. FC7, a foreign corpo-
ration that is not a controlled foreign corporation
within the meaning of section 957(a), owns all of the
preferred shares. Corp M and FC7 cause the govern-
ing documents of FC6 to provide that no dividends
maybepaidtothecommonshareholdersuntilFC6
cumulatively earns $100,000x of income. FC6 and
Corp M each use the calendar year as a taxable year.
Corp M and FC7 are shareholders of FC6 for all
of 2005. For 2005, FC6 has $50x of earnings and
profits, and income of $50x with respect to which
amounts are required to be included in gross income
of United States shareholders under section 951(a).
2005–40 I.R.B.618October 3, 2005

In 2005, FC6 distributes as a dividend $8x to FC7
with respect to FC7’s preferred shares. FC6 makes
no other distributions during that year.
(ii)Analysis. The agreement restricting FC6’s
ability to pay dividends to common shareholders un-
til FC6 cumulatively earns $100,000x of income is
a restriction or other limitation, within the meaning
of paragraph (e)(5) of this section, and will be disre-
garded for purposes of calculating Corp M’spro rata
share of subpart F income. The non-discretionary
distribution rights of the preferred shares are not a
restriction or other limitation within the meaning of
paragraph (e)(5) of this section. If the total $50x of
earnings were distributed on December 31, 2005, $8x
would be distributed with respect to FC7’s preferred
shares and the remainder, $42x, would be distributed
with respect to Corp M’s common shares. Accord-
ingly, under paragraph (e)(3)(i) of this section, Corp
M’spro ratashare of FC6’s subpart F income is $42x
for taxable year 2005.
Example 7.(i)Facts. FC8, a controlled foreign
corporation within the meaning of section 957(a), has
outstanding 40 shares of common stock and 10 shares
of 4-percent voting preferred stock with a par value
of $50x per share. Pursuant to the terms of the pre-
ferred stock, FC8 has the right to redeem at any time,
in whole or in part, the preferred stock. FP, a foreign
corporation, owns all of the preferred shares. Corp
G, a domestic corporation wholly owned by FP and
a United States shareholder of FC8, within the mean-
ing of section 951(b), owns all of the common shares.
FC8 and Corp G each use the calendar year as a tax-
able year. FP and Corp G are shareholders of FC8 for
all of 2005. For 2005, FC8 has $100x of earnings and
profits, and income of $100x with respect to which
amounts are required to be included in gross income
of United States shareholder under section 951(a). In
2005, FC8 distributes as a dividend $20x to FP with
respect to FP’s preferred shares. FC8 makes no other
distributions during that year.
(ii)Analysis. Pursuant to paragraph (e)(3)(ii)(B)
of this section, the redemption rights of the preferred
shares will not be treated asa discretionary distribu-
tion right under paragraph (e)(3)(ii)(A) of this sec-
tion. Further, if FC8 were treated as having redeemed
any preferred shares under paragraph (e)(3)(i) of this
section, the redemption would be treated as a distribu-
tion to which section 301 applies under section 302(d)
due to FP’s constructive ownership of the common
shares. However, pursuant to paragraph (e)(4) of this
section, no amount of earnings and profits would be
allocated to the preferred shareholders on the hypo-
thetical distribution date, under paragraph (e)(3)(i) of
this section, as a result of FC8’s right to redeem, in
whole or in part, the preferred shares. FC8’s redemp-
tion rights with respect to the preferred shares can-
not affect the allocation of earnings and profits be-
tween FC8’s shareholders. Therefore, the redemption
rights are not restrictions or other limitations within
the meaning of paragraph (e)(5) of this section. Ad-
ditionally, the non-discretionary distribution rights of
the preferred shares are not restrictions or other limi-
tations within the meaning of paragraph (e)(5) of this
section. Therefore, if the total $100x of earnings were
distributed on December 31, 2005, $20x would be
distributed with respect to FP’s preferred shares and
the remainder, $80x, would be distributed with re-
spect to Corp G’s common shares. Accordingly, un-
der paragraph (e)(3)(i) of this section, Corp G’spro
ratashare of FC8’s subpart F income is $80 for tax-
able year 2005.
Example 8.(i)Facts. FC9, a controlled foreign
corporation within the meaning of section 957(a), has
outstanding 40 shares of common stock and 60 shares
of 6-percent, nonparticipating, nonvoting, preferred
stock with a par value of $100x per share. Individ-
ual J, a United States shareholder of FC9, within the
meaning of section 951(b), who uses the calendar
year as a taxable year, owns 30 shares of the common
stock, and 15 shares of the preferred stock during tax
year 2005. The remaining 10 common shares and 45
preferred shares of FC9 are owned by Foreign Indi-
vidual N, a foreign individual. Individual J and Indi-
vidual N are shareholders of FC9 for all of 2005. For
taxable year 2005, FC9 has $1,000x of earnings and
profits, and income of $500x with respect to which
amounts are required to be included in gross income
of United States shareholders under section 951(a).
(ii)Analysis. The non-discretionary distribution
rights of the preferred shares are not a restriction
or other limitation within the meaning of paragraph
(e)(5) of this section. If the total $1,000x of earnings
and profits were distributed on December 31, 2005,
$360x (0.06 x $100x x 60) would be distributed with
respect to FC9’s preferred stock and $640x ($1,000x
minus $360x) would be distributed with respect to
its common stock. Accordingly, of the $500x with
respect to which amounts are required to be included
in gross income of United States shareholders under
section 951(a), $180x ($360x/$1,000x x $500x)
is allocated to the outstanding preferred stock and
$320x ($640x/$1,000x x $500x) is allocated to the
outstanding common stock. Therefore, under para-
graph (e)(3)(i) of this section, Individual J’spro rata
share of such amounts for 2005 is $285x [($180x x
15/60)+($320x x 30/40)].
Example 9. [Reserved].
(7)Effective dates. This paragraph (e)
applies for taxable years of a controlled
foreign corporation beginning on or after
January 1, 2005. However, if the appli-
cation of this paragraph (e) for purposes
of a related Internal Revenue Code provi-
sion,suchassection1248,resultsinanal-
location to the stock of such corporation of
earnings and profits that have already been
allocated to the stock for an earlier year un-
der the prior rules of §1.951–1(e), as con-
tained in 26 CFR Part 1 revised April 1,
2005, then the prior rules will continue to
apply to the extent necessary to avoid such
duplicative allocation.

Hurricane Katrina
Notice 2005–66
PURPOSE
This notice under section 7508A post-
pones the deadlines for certain acts per-
formed by the Internal Revenue Service
(IRS) with respect to certain taxpayers af-
fected by Hurricane Katrina. In response
to Hurricane Katrina, the President issued
four federal disaster declarations on Au-
gust 28, 2005 and August 29, 2005, cover-
ing certain areas in Alabama, Mississippi,
Louisiana, and Florida. The areas identi-
fied in the declarations each constitute a
“covered disaster area” within the meaning
of section 301.7508A–1(d)(2) of the Pro-
cedure and Administration Regulations.
The August 28, 2005 declaration for
Florida covers the following three counties

By news releases issued on August 30,
2005, September 2, 2005, and Septem-
ber 8, 2005, the Internal Revenue Ser-
vice granted relief for taxpayers affected
by Hurricane Katrina. See IR–2005–84,
IR–2005–91, and IR–2005–96. The news
releases provided that taxpayers affected
by the disaster will have until January 3,
2006, to file tax returns and submit pay-
ments. In addition, the news releases an-
nounced that the IRS will abate interest
and any late filing or late payment penal-
ties that otherwise would apply. This re-
lief includes the September 15, 2005 due
date for estimated taxes and for calendar-
year corporate returns with automatic ex-
tensions.
BACKGROUND
Section 7508A provides the Secretary
with authority to postpone the time for per-
forming certain acts under the internal rev-
enue laws for a taxpayer affected by a Pres-
identially declared disaster as defined in
section 1033(h)(3). Pursuant to section
7508A(a), a period of up to one year may
be disregarded in determining whether the
performance of certain acts is timely un-
der the internal revenue laws. Section
7508A(a)(1) includes the acts listed in sec-
tion 7508(a) as those that may be post-
poned.See also§ 301.7508A–1(c)(1).
Section 7508(a) and § 301.7508A–1(c)(1)
include a number of acts performed by tax-
payers for which section 7508A relief may
apply. These include, but are not limited
to: the filing of certain tax returns; the
payment of certain taxes; the filing of a
Tax Court petition; the filing of a claim for
credit or refund of tax; and the bringing of
a lawsuit upon a claim for credit or refund
of tax.
Section 301.7508A–1(d)(1) describes
several types of “affected taxpayers” eligi-
ble for relief under section 7508A. These
taxpayers include any individual whose
principal residence, and any business en-
tity whose principal place of business, is
located in the covered disaster area; any
individual who is a relief worker affil-
iated with a recognized government or
philanthropic organization and who is as-
sisting in the covered disaster area; any
individual whose principal residence, and
any business entity whose principal place
of business, is not located in the covered
disaster area, but whose records necessary
to meet a filing or paying deadline are
maintained in the covered disaster area;
any estate or trust that has tax records nec-
essary to meet a filing or paying deadline
in a covered disaster area; any spouse of
an affected taxpayer, solely with regard to
a joint return of the husband and wife; and
any other person determined by the IRS
to be affected by a Presidentially declared
disaster.
ACTSPERFORMEDBYTHE
GOVERNMENT
In News Release IR–2005–84, News
Release IR–2005–91, and News Release
IR–2005–96, the IRS granted affected
taxpayers additional time until January 3,
2006, to file tax returns, to submit tax pay-
ments, and to perform certain time-sensi-
tive acts listed in § 301.7508A–1(c)(1) and
in Rev. Proc. 2005–27, 2005–20 I.R.B.
1050 (May 16, 2005). In consideration of
the additional time that affected taxpay-
ers have been granted to perform certain
acts, this notice extends the period for the
government to take certain actions. Un-
der the authority of section 7508A(a)(1)

Weighted Average Interest
Rates Update
Notice 2005–67
This notice provides guidance as to the
corporate bond weighted average interest
rate and the permissible range of interest
rates specified under § 412(b)(5)(B)(ii)(II)
of the Internal Revenue Code. In ad-
dition, it provides guidance as to the
interest rate on 30-year Treasury securi-
ties under § 417(e)(3)(A)(ii)(II), and the
weighted average interest rate and permis-
sible ranges of interest rates based on the
30-year Treasury securities rate.
CORPORATE BOND WEIGHTED
AVERAGE INTEREST RATE
Sections412(b)(5)(B)(ii)and
412(l)(7)(C)(i), as amended by the Pen-
sion Funding Equity Act of 2004, provide
that the interest rates used to calculate cur-
rent liability and to determine the required
contribution under § 412(l) for plan years
beginning in 2004 or 2005 must be within
a permissible range based on the weighted
average of the rates of interest on amounts

vestment grade corporate bonds during the
4-year period ending on the last day before
the beginning of the plan year.
Notice 2004–34, 2004–1 C.B. 848, pro-
vides guidelines for determining the cor-
porate bond weighted average interest rate
and the resulting permissible range of in-

ity. That notice establishes that the corpo-
rate bond weighted average is based on the
monthly composite corporate bond rate de-
rived from designated corporate bond in-
dices.
The composite corporate bond rate for
August 2005 is 5.42 percent. Pursuant
to Notice 2004–34, the Service has de-
termined this rate as the average of the

Treatment of Certain Amounts
Paid to Section 170(c)
Organizations Under Certain
Employer Leave-Based
Donation Programs
Notice 2005–68
In view of the extreme need for chari-
table relief in the aftermath of Hurricane
Katrina, employers may have adopted or
may be considering adopting leave-based
donation programs to aid victims of this
hurricane. Under these programs employ-
ees elect to forgo vacation, sick, or per-
sonal leave in exchange for cash payments
an employer makes to organizations de-
scribed in § 170(c) of the Internal Revenue
Code (§ 170(c) organizations) for the relief
of victims of Hurricane Katrina. This no-
tice provides guidance on the treatment of
these cash payments for income and em-
ployment tax purposes.
Notice 2001–69, 2001–2 C.B. 491,
as modified and superseded by Notice
2003–1, 2003–1 C.B. 257, provided sim-
ilar guidance in view of the extreme
need for charitable relief following the
September 11, 2001, terrorist attacks.
This guidance is provided in view of the
extraordinary damage and destruction
caused by Hurricane Katrina.
The Service will not assert that cash
payments an employer makes to § 170(c)
organizations in exchange for vacation,
sick, or personal leave that its employees
elect to forgo constitute gross income or
wages of the employees if the payments
are: (1) made to the § 170(c) organiza-
tions for the relief of victims of Hurricane
Katrina; and (2) paid to the § 170(c) orga-
nizations before January 1, 2007.
Similarly, the Service will not assert
that the opportunity to make such an elec-
tion results in constructive receipt of gross
income or wages for employees. Elect-
ing employees may not claim a charitable
contribution deduction under § 170 with
respect to the value of forgone leave ex-
cluded from compensation and wages.
The Service will not assert that an em-
ployer will be only permitted to deduct
these cash payments under the rules of
§ 170 rather than the rules of § 162. Cash
payments to which this guidance applies
need not be included in Box 1, 3 (if appli-
cable), or 5 of the Form W–2.

Relief From Certain
Low-Income Housing
Credit Requirements Due
to Hurricane Katrina
Notice 2005–69
The Internal Revenue Service is sus-
pending certain requirements under § 42
of the Internal Revenue Code for low-in-
come housing credit projects in the United
States as a result of the devastation caused
by Hurricane Katrina. This relief is being
granted pursuant to the Service’s authority
under § 42(n) and § 1.42–13(a) of the In-
come Tax Regulations.
BACKGROUND
On August 29, 2005, the President
declared major disasters for the States
of Alabama, Louisiana, and Mississippi
as a result of Hurricane Katrina. These
declarations were made under the Robert
T. Stafford Disaster Relief and Emer-
gency Assistance Act, Title 42 U.S.C.
5121–5206 (2000 and Supp. II 2002).
Subsequently, the Federal Emergency
Management Agency (FEMA) designated
jurisdictions for Individual Assistance.
State housing creditagencies through-
out the United States have requested that
the Service allow owners of low-income
housing credit projects to provide tempo-
rary housing in vacantunits to individuals
who resided in jurisdictions designated
for Individual Assistance in Alabama,
Louisiana, and Mississippi and who have
been displaced because their residences
were destroyed or damaged as a result
of the devastation caused by Hurricane
Katrina (displaced individuals). State
housing credit agencies have further re-
quested that the temporary housing of
the displaced individuals in low-income
units without regard to income not cause
the owners to lose low-income housing
credits. Based upon these requests and
because of the widespread damage to
housing caused by Hurricane Katrina, the
Service has determined that any housing
credit agency of a state or a possession
of the United States (state housing credit
agency) may provide approval to project
owners in their respective state or pos-
session to provide temporary emergency
housing for displaced individuals in accor-
dance with this notice.
I. SUSPENSION OF INCOME
LIMITATIONS
The Service has determined that it is
appropriate to temporarily suspend certain
income limitation requirements under § 42
for certain qualified low-income projects.
The suspension will apply to low-income
housing projects approved by the state
2005–40 I.R.B.622October 3, 2005

housing credit agency, in which vacant
units are rented to displaced individuals.
The state housing credit agency will deter-
mine the appropriate period of temporary
housing for each project, not to extend
beyond September 30, 2006 (temporary
housing period).
II. STATUS OF UNITS
A. Units in the first year of the credit
period
A displaced individual temporarily
occupying a unit during the first year of
the credit period under § 42(f)(1) will be
deemed a qualified low-income tenant
for purposes of determining the project’s
qualified basis under § 42(c)(1), and for
meeting the project’s 20–50 test or 40–60
test as elected by the project owner under
§ 42(g)(1). After the end of the temporary
housingperiodestablishedbythestate
housing credit agency (not to extend be-
yond September 30, 2006), a displaced
individual will no longer be deemed a
qualified low-income tenant.
B. Vacant units after the first year of the
credit period
During the temporary housing pe-
riod established by a state housing credit
agency, the status of a vacant unit (that is,
market-rate or low-income for purposes
of § 42 or never previously occupied)
after the first year of the credit period
that becomes temporarily occupied by a
displaced individual remains the same as
the unit’s status before the displaced in-
dividual moves in. Displaced individuals
temporarily occupying vacant units will
not be treated as low-income tenants un-
der § 42(i)(3)(A)(ii) (a low-income unit
that was vacant before the effective date
of this notice will continue to be treated
as a vacant low-income unit even if it
houses a displaced individual, a market
rate unit that was vacant before the effec-
tive date of this notice will continue to be
treated as a vacant market rate unit even
if it houses a displaced individual, and a
unit that was never previously occupied
beforetheeffectivedateofthisnoticewill
continue to be treated as a unit that has
never been previously occupied even if
it houses a displaced individual). Thus,
the fact that a vacant unit becomes oc-
cupied by a displaced individual will not
affect the building’s applicable fraction
under § 42(c)(1)(B) for purposes of de-
termining the building’s qualified basis,
nor will it affect the 20–50 test or 40–60
test of § 42(g)(1). If the income of oc-
cupants in low-income units exceeds 140
percent of the applicable income limita-
tion, the temporary occupancy of a unit
by a displaced individual will not cause
application of the available unit rule under
§ 42(g)(2)(D)(ii). In addition, the project
owner is not required during the temporary
housing period to make attempts to rent to
low-income individuals the low-income
units housing displaced individuals.
III. SUSPENSION OF
NON-TRANSIENT REQUIREMENTS
The non-transient use requirement of
§ 42(i)(3)(B)(i) shall not apply to any
unit providing temporary housing to a
displaced individual during the temporary
housingperioddeterminedbythestate
housing credit agency in accordance with
section I of this notice.
IV. OTHER REQUIREMENTS
All other rules and requirements of
§ 42 will continue to apply during the
temporary housing period established by
the state housing credit agency. After the
end of the temporary housing period, the
applicable income limitations contained
in § 42(g)(1), the available unit rule un-
der § 42(g)(2)(D)(ii), the non-transient
requirement of § 42(i)(3)(B)(i), and the
requirement to make reasonable attempts
to rent vacant units to low-income indi-
viduals shall resume. If a project owner
offers to rent to a displaced individual after
the end of the temporary housing period,
a displaced individual must be certified
under the requirements of § 42(i)(3)(A)(ii)
and § 1.42–5(b) and (c) to be a qualified
low-income tenant. To qualify for the re-
lief in this notice, the project owner must
additionally meet all of the following re-
quirements:
(1)Major Disaster Area
The displaced individual must have
resided in an Alabama, Louisiana, or
Mississippi jurisdiction designated for In-
dividual Assistance by FEMA as a result
of Hurricane Katrina.
(2)Approval of State Housing Credit
Agency
The project owner must obtain approval
from the state housing credit agency for
the relief described in this notice. The
state housing credit agency will determine
the appropriate period of temporary hous-
ing for each project, not to extend beyond
September 30, 2006.
(3)Certifications and Recordkeeping
To comply with the requirements of
§ 1.42–5, project owners are required to
maintain and certify certain information
concerning each displaced individual tem-
porarily housed in the project, specifically:
name, address of damaged residence, so-
cial security number, and a statement
signed under penalties of perjury by the
displaced individualthat, because of dam-
age to the individual’s residence in an
Alabama, Louisiana, or Mississippi juris-
diction designated for Individual Assis-
tance by FEMA as a result of Hurricane
Katrina, the individual requires tempo-
rary housing. The owner must list the
project on the National Emergency Re-
source Registry (NERR) maintained by
the Department of Homeland Security.
The NERR assists coordination efforts
between resources that are needed and re-
sources that are available. The web site for
listing the project is:www.SWERN.gov.
The owner must also certify the date
the displaced individual began temporary
occupancy and the date the project will
discontinue providing temporary housing
as established by the state housing credit
agency. The certifications and record-
keeping for displacedindividuals must
be maintained as part of the annual com-
pliance monitoring process with the state
housing credit agency.
(4)Rent Restrictions
Rents for the low-income units housing
displaced individuals must not exceed the
existing rent-restricted rates for the low-
income units established under § 42(g)(2).
(5)Protection of Existing Tenants
Existing tenants in occupied low-in-
come units cannot be evicted or have their
tenancy terminated as a result of efforts to
October 3, 20056232005–40 I.R.B.

provide temporary housing for displaced
individuals.

Background
Section 482 of the Internal Revenue
Code generally provides that the Secretary
may allocate gross income, deductions,
credits, and allowances between or among
two or more taxpayers that are owned or
controlled by the same interests in order
to prevent evasion of taxes or clearly to
reflect income of a controlled taxpayer.
The second sentence of section 482 added
by the Tax Reform Act of 1986 enunciates
the “commensurate with income” standard
that in the case of any transfer (or license)
of intangible property (within the mean-
ing of section 936(h)(3)(B)), the income
with respect to such transfer or license
shall be commensurate with the income
attributable to the intangible. Public Law
99–5143, 1231(e)(1),reprinted in1986–3
C.B. (Vol. 1) 1, 479–80.
Comprehensive regulations under sec-
tion 482 were published in theFederal
Register(T.D. 6952, 1968–1 C.B. 218 [33
FR 5849]) on April 16, 1968, and were
revised and updated by transfer pricing
regulations in theFederal Register(T.D.
8552, 1994–2 C.B. 93 [59 FR 34971],
T.D. 8632, 1996–1 C.B. 85 [60 FR 65553],
T.D. 8670, 1996–1 C.B 99 [61 FR 21955],
October 3, 20056252005–40 I.R.B.

and T.D. 9088, 2003–2 C.B. 841 [68 FR
51171]) on July 8, 1994, December 20,
1995, May 13, 1996, and August 26, 2003,
respectively.
The 1968 regulations contained guid-
ance regarding the sharing of costs and
risks. See §1.482–2A(d)(4). The 1968
regulations were replaced in 1996 by
§1.482–7 regarding the sharing of costs
and risks (the 1996 regulations were fur-
ther modified in 2003 with respect to
stock-based compensation).
Experience in the administration of ex-
isting §1.482–7 has demonstrated the need
for additional regulatory guidance to im-
prove compliance with, and administra-
tion of, the cost sharing rules. In partic-
ular, there is a need for additional guid-
ance regarding the external contributions
for which arm’s length consideration must
be provided as a condition to entering into
a cost sharing arrangement. The consider-
ation for this type of external contribution
is referred to in the existing regulations as
thebuy-in. Furthermore, additional guid-
ance is needed on methods for valuing
these external contributions. The proposed
regulations also provide the opportunity to
address other technical and procedural is-
sues that have arisen in the course of the
administration of the cost sharing rules.
Explanation of Provisions
A. Overview
Under a cost sharing arrangement, re-
lated parties agree to share the costs and
risks of intangible development in pro-
portion to their reasonable expectations of
the extent to which they will relatively
benefit from their separate exploitation of
the developed intangibles. The existing
§1.482–7 regulations and these proposed
regulations provide rules governing cost
sharing arrangements consistent with the
commensurate with income standard un-
der the statute and the general arm’s length
standard under the section 482 regulations.
Comment letters and other information
available to the Treasury Department and
IRS have provided limited information on
third-party arrangements that are asserted
to be similar to cost sharing arrangements.
Typically, in the context of discussion con-
cerning the current §1.482–7 regulations,
information has been provided on certain
arrangements involving cost plus research
and development or government contracts,
which, while no doubt arm’s length trans-
actions, are not viewed by the Treasury
Department and IRS as analogous to cost
sharing arrangements.
Thus,in accordance with
§1.482–1(b)(1), the task is to pro-
vide guidance relative to cost sharing
arrangements regarding “the results that
would have been realizedif uncontrolled
taxpayershad engagedin the same trans-
action under the same circumstances.”
(Emphasis added.) This guidance is
necessary because of the fundamental
differences in cost sharing arrangements
between related parties as compared to
any superficially similar arrangements
that are entered into between unrelated
parties. Such other arrangements typically
involve a materially different division of
costs, risks, and benefits than in cost shar-
ing arrangements under the regulations.
For example, other arrangements may
contemplate joint, rather than separate,
exploitation of results, or may tie the
division of actual results to the magni-
tude of each party’s contributions (for
example, by way of preferential returns).
Those types of arrangements are not
analogous to a cost sharing arrangement
in which the controlled participants divide
contributionsin accordance with reason-
ably anticipated benefits from separate
exploitation of the resulting intangibles.
For purposes of determining the results
that would have been realized under an
arm’s length cost sharing arrangement,
the proposed regulations adopt as a fun-
damental concept aninvestor modelfor
addressing the relationships and contribu-
tions of controlled participants in a cost
sharing arrangement. Under this model,
each controlled participant may be viewed
as making an aggregate investment, attrib-
utable to both cost contributions (ongoing
share of intangible development costs)
and external contributions (the preexisting
advantages which the parties bring into the
arrangement), for purposes of achieving
an anticipated return appropriate to the
risks of the cost sharing arrangement over
the term of the development and exploita-
tion of the intangibles resulting from the
arrangement. In particular, the investor
model frames the guidance in the proposed
regulations for valuing the external contri-
butions that parties at arm’s length would
not invest, along with their ongoing cost
contributions, in the absence of an appro-
priate reward. In this regard, valuations
are not appropriate if an investor would
not undertake to invest in the arrangement
because its total anticipated return is less
than the total anticipated return that could
have been achieved through an alternative
investment that is realistically available to
it.
The investor model is grounded in the
legislative history of the Tax Reform Act
of 1986 which provided in pertinent part
as follows:
In revising section 482, the conferees
do not intend to preclude the use of
certainbona fidecost-sharing arrange-
ments as an appropriate method of al-
locating income attributable to intangi-
bles among related parties, if and to the
extent such agreements are consistent
with the purposes of this provision that
the income allocated among the par-
ties reasonably reflect the actual eco-
nomic activity undertaken by each. Un-
der such abona fidecost-sharing ar-
rangement, the cost-sharer would be ex-
pected to bear its portion of all research
and development costs, on successful as
well as unsuccessful products within an
appropriate product area, and the cost
of research and development at all rel-
evant developmental stages would be
included. In order for cost-sharing ar-
rangements to produce results consis-
tent with the changes made by the Act
to royalty arrangements, it is envisioned
that the allocation of R&D cost-sharing
arrangements generally should be pro-
portionate to profit as determined be-
fore deduction for research and devel-
opment.In addition, to the extent, if
any, that one party is actually contribut-
ing funds toward research and develop-
ment at a significantly earlier point in
time than the other, or is otherwise ef-
fectively putting its funds at risk to a
greater extent than the other, it would
be expected that an appropriate return
would be required to such party to re-
flect its investment.

(1986) (emphasis supplied).
There are special implications that are
derived from determining the arm’s length
compensation for external contributions
in line with the investor model. In eval-
uating that arm’s length compensation,
it is appropriate, consistent with the in-
2005–40 I.R.B.626October 3, 2005

vestor model, to determine (1) what an
investor would pay at the outset of a cost
sharing arrangement for an opportunity to
invest in that arrangement, and (2) what
a participant with external contributions
would require as compensation at the
outset of a cost sharing arrangement to
allow an investor to join in the investment.
The appropriate “price” of undertaking a
risky investment is typically determined
at the time the investment is undertaken,
based on the ex ante expectations of the
investors. Given the uncertainty about
whether and to what extent intangibles
will be successfully developed under a
cost sharing arrangement, ex post inter-
pretations of ex ante expectations are
inherently unreliable and susceptible to
abuse. Accordingly, an important implica-
tion of determining the arm’s length result
under the investor model, reflected in the
methods, is that compensation for external
contributions is analyzed and valued ex
ante. The ex ante perspective is funda-
mental to achieving arm’s length results.
Accordingly, the proposed regulations
provide guidance under section 482 that
would replace the existing regulations
under §1.482–7 relating to cost sharing
arrangements. They revise §1.482–7 in
light of the experience of both the IRS and
taxpayers with the existing regulations.
The proposed regulations also restructure
the format of the existing regulations to
be more consistent with that of the 1994
regulations (for example, §§1.482–3 and
1.482–4) and to add organizational clarity.
The proposed regulations begin by
specifying the transactions relevant to a
cost sharing arrangement. Importantly,
the proposed regulations acknowledge
that in a typical cost sharing arrangement,
at least one controlled participant pro-
vides resources or capabilities developed,
maintained, or acquired externally to the
arrangement that are reasonably antici-
pated to contribute to the development
of intangibles under the arrangement,
namely what are referred to as external
contributions. Thus, the proposed regu-
lations integrate into the definition of a
cost sharing arrangement both “cost shar-
ing transactions” regarding the ongoing
sharing of intangible development costs
as well as “preliminary or contemporane-
ous transactions” by which the controlled
participants compensate each other for
their external contributions to the arrange-
ment (that is, what the existing regulations
refer to as the “buy-in”). The proposed
regulations provide that §1.482–7 only
governs arrangements that are within (or
which the controlled taxpayers reasonably
concluded to be within) the definition of a
cost sharing arrangement. Arrangements
outside that definition must be analyzed
under the other sections of the section
482 regulations to determine whether they
achieve arm’s length results.
The proposed regulations provide sup-
plemental guidance on the valuation of the
arm’s length amount to be charged in a
preliminary or contemporaneous transac-
tion. The proposed regulations clarify that
the valuation of the rights associated with
the external contribution that is compen-
sated in a preliminary or contemporaneous
transaction cannot be artificially limited
by purported conditions or restrictions.
Rather, the arm’s length compensation,
and the applicable method used to deter-
mine that compensation, must reflect the
type of transaction and contractual terms
of a “reference transaction” by which the
benefit of exclusive and perpetual rights
in the relevant resources or capabilities
are provided. This compensation will be
determined by a method that will yield a
value for the obligation of any given con-
trolled participant that is consistent with
that participant’s share of the combined
value of the external contribution to all
controlled participants.
The proposed regulations set forth new
specified methods and provide rules for
application of existing specified methods,
for purposes of determining the arm’s
length compensation due with respect to
external contributions in preliminary or
contemporaneous transactions. The pro-
posed regulations also enunciate general
principles governingall methods, speci-
fied and unspecified, for these purposes.
The proposed regulations provide guid-
ance on allocations that the Commissioner
may make to more clearly reflect arm’s
length results for the controlled taxpayers’
cost sharing transactions and preliminary
or contemporaneous transactions. In par-
ticular, building again on the investor
model, the proposed regulations provide
guidance on the periodic adjustments that
the Commissioner may make in situations
where the actually experienced results
of a controlled participant’s investment
attributable to costcontributions and ex-
ternal contributions is widely divergent
from reasonable expectations at the time
of the investment. Exceptions are pro-
vided, including one under which the
taxpayer may establish that the differen-
tial is due to events beyond its control
that are extraordinary and not reasonably
anticipated (including business growth
that was not reasonably anticipated). The
proposed regulations provide that periodic
adjustments may only be made by the
Commissioner.
Finally, the proposed regulations in-
clude provisions to facilitate administra-
tion of, and compliance with, the cost
sharing rules. These include contractual
provisions required for cost sharing ar-
rangements, documentation that must be
maintained (and produced upon request
by the IRS), accounting requirements, and
reporting requirements. Transition rules
are provided for modified compliance in
the case of qualified cost sharing arrange-
ments under existing §1.482–7, as well
as rules for terminating such grandfather
status. The proposed regulations also
make conforming and other changes to
provisions of the current regulations under
sections 482 and 6662 that are related to
this guidance.
B. Basic Rules Applicable to CSAs
1. General rule — proposed §1.482–7(a)
Consistent with the rules governing
other controlled transactions (for exam-
ple, transfers of tangibles and intangibles
under existing §§1.482–3 and 1.482–4),
proposed §1.482–7(a) provides that the
arm’s length amount charged in a con-
trolled transaction reasonably anticipated
to contribute to developing intangibles
pursuant to a cost sharing arrangement
must be determined under a method de-
scribed in the proposed regulations.
The controlled participants must share
intangible development costs of the in-
tangibles developed or to be developed
(the cost shared intangibles) in cost sharing
transactions in proportion to their shares
of reasonably anticipated benefits (RAB
shares) from exploiting the cost shared in-
tangibles.
The controlled participants must also
compensate other controlled participants
for their external contributions in prelim-
inary or contemporaneous transactions.
October 3, 20056272005–40 I.R.B.

The arm’s length amount charged in a
preliminary or contemporaneous transac-
tion must be determined pursuant to the
method or methods under the other pro-
vision or provisions of the section 482
regulations, as supplemented by proposed
§1.482–7(g), applicable to the reference
transaction reflected by the preliminary
or contemporaneous transaction. Such
method will yield a value for the obliga-
tion of each obligor inthe preliminary or
contemporaneous transaction that is con-
sistent with the product of the combined
value to all controlled participants of the
external contribution that is the subject of
the preliminary or contemporaneous trans-
action multiplied by the obligor’s RAB
share.
Contributions to developing the cost
shared intangibles made by a controlled
taxpayer that is not a controlled participant
in the cost sharing arrangement must be
determined pursuant to §1.482–4(f)(3)(iii)
(Allocations with respect to assistance to
the owner). Arm’s length consideration
for the transfer by a controlled participant
of an interest in a cost shared intangible
at any time (whether during the term, or
upon or after the termination of a cost
sharing arrangement) must be determined
under the rules of §§1.482–1 and 1.482–4
through 1.482–6.
The proposed regulations provide that
if an arrangement comes within the defi-
nition of a cost sharing arrangement, it is
subject to §1.482–7 (see next section of
this Preamble for discussion of the defini-
tion of a cost sharing arrangement). Other
arrangements that are not cost sharing ar-
rangements (or arenot treated as such)
must be analyzed under the other provi-
sions of the section 482 regulations to de-
termine whether they achieve arm’s length
results.
2. Definition of a CSA — proposed
§1.482–7(b)
a. CSA Transactions in General
Under §1.482–1(b)(1), a “controlled
transaction meets the arm’s length stan-
dard if the results of the transaction are
consistent with the results thatwould have
been realizedif uncontrolled taxpayers
had engagedin the same transaction un-
der the same circumstances....” (Emphasis
added.) Thus, it is important to define
with reasonable precision the category of
arrangements treated as cost sharing ar-
rangements, their terms, and the functions
and risks assumed by the participants in
such arrangements. The determination of
what “would have been” the arm’s length
results of such transactions is based on
those definitions.
Proposed §1.482–7(b) identifies two
groups of transactions that are integral
to a cost sharing arrangement — cost
sharing transactions and preliminary or
contemporaneous transactions. A cost
sharing transaction orCSTis a transac-
tion in which the controlled participants
share the intangible development costs
of one or more cost shared intangibles in
proportion to their respective shares of
reasonably anticipated benefits from their
individual exploitation of their interests in
the cost shared intangibles that they obtain
under the arrangement. CSTs reflect the
results that would have been expected in
a cost sharing arrangement between un-
controlled taxpayers that did not bring any
external contributions to the arrangement.
In other words, if uncontrolled taxpayers
started in a true “green field,” they would
be expected to agree to split ongoing costs
of the research in proportion to the rela-
tive value of their respective reasonably
anticipated benefits from the arrangement.
The proposed regulations are premised
in part, however, on the fact that at least
one controlled participant typically pro-
vides external contributions to a cost
sharing arrangement. Thus, the proposed
regulations integrate into the definition of
a cost sharing arrangement not only the
CSTs for the ongoing sharing of intangible
development costs, but also the prelimi-
nary or contemporaneous transactions or
PCTsby which the controlled participants
compensate one another for their respec-
tive external contributions. The necessity
of PCTs in connection with cost sharing
arrangements was anticipated in the leg-
islative history of the Tax Reform Act of
1986:
In addition, to the extent, if any, that one
party is actually contributing funds to-
ward research and development at a sig-
nificantly earlier point in time than the
other, or is otherwise effectively putting
its funds at risk to a greater extent than
the other, it would be expected that an
appropriate return would be required to
such party to reflect its investment.
H.R. Conf. Rep. No. 99–841 at II–638
(1986).
b. Constituent Elements of a CSA —
Proposed §1.482–7(b)(1)
The proposed regulations define a cost
sharing arrangement orCSAas a contrac-
tual agreement to share the costs of one or
more intangibles that meet three substan-
tive and four administrative requirements.
The termCSA, as defined, would replace
the termqualified cost sharing arrange-
mentemployed in the existing regulations.
The substantive requirements are that the
controlled participants (1) divide all inter-
ests in cost shared intangibles on a territo-
rial basis, (2) enter into and effect all CSTs
and all PCTs, and (3) as a result, individu-
ally own and exploit their respective inter-
ests in the cost shared intangibles without
any further obligation to compensate one
another for such interests. The adminis-
trative requirements are that the controlled
participants substantially comply with (1)
the CSA contractual requirements, (2) the
CSA documentation requirements, (3) the
CSA accounting requirements, and (4) the
CSA reporting requirements.
The Treasury Department and the IRS
recognize that a CSA, as defined, repre-
sents one possible arrangement by which
parties may choose to share the costs,
risks, and benefits of intangible develop-
ment. Other arrangements, however, may
involve a materially different division of
costs, risks, and benefits in contrast to a
CSA. For example, other arrangements
may contemplate joint, rather than sepa-
rate, exploitation of results, or may tie the
division of actual results to the magnitude
of each party’s contributions (for exam-
ple, by way of preferential returns), rather
than divide contributions in accordance
with reasonably anticipated benefits from
separate exploitation. Given such differ-
ences, the guidance under §1.482–7, as
applicable to CSAs, is not appropriate to
evaluate what would have been the arm’s
length results of these other arrangements
that do not constitute CSAs when they are
undertaken among controlled taxpayers.
In such cases the proposed regulations
direct taxpayers to guidance under other
provisions of the section 482 regulations
to determine whether such arrangements
achieve arm’s length results.
2005–40 I.R.B.628October 3, 2005

c. External Contributions and PCTs —
Proposed §1.482–7(b)(3)(i) Through (iv)
PCTs are the transactions by which the
controlled participants compensate one an-
other for their external contributions to the
CSA. External contributions are any re-
sources or capabilities which one or more
controlled participants bring to a CSA that
were developed, maintained, or acquired
externally to the CSA (whether prior to or
during the course of the CSA), and that
are reasonably anticipated to contribute to
developing cost shared intangibles. For
example, one controlled participant may
have promising in-process technology, or
a developed and successful first genera-
tion technology, that may reasonably be
anticipated to provide a platform for fu-
ture generation technology to be devel-
oped under the CSA. As another example,
one controlled participant may have an ex-
perienced research team that could reason-
ably be anticipated to be particularly suited
to carrying out the development contem-
plated under the CSA. The proposed regu-
lations exclude land, depreciable tangible
property, and other resources acquired by
intangible development costs, since they
are compensated by CSTs. See discussion
of proposed §1.482–7(d).
The Treasury Department and the IRS
believe that uncontrolled parties entering
into a long term commitment to share in-
tangible development costs would require
an agreement upfront that all external con-
tributions be made available to the fullest
extent for the full period over which they
are reasonably anticipated to be needed.
Accordingly, the proposed regulations
introduce the concept of the reference
transaction orRTin order to ensure that
compensation for external contributions to
the CSA reflects the full economic value of
resources or capabilities that a participant
brings to the CSA. The RT is a transac-
tion providing the benefit of all rights,
exclusively and perpetually, in a resource
or capability described above, apart from
the rights to exploit an existing intangible
without further development (see section
of Preamble below regarding §1.482–7(c)
(Make-or-sell rights excluded)). The
arm’s length compensation pursuant to
the PCT, and the applicable method used
to determine such compensation, must
reflect the type of transaction and con-
tractual terms of the RT. The controlled
participants must enter into a PCT as of
the earliest date (whether on or after the
date the CSA is entered into) on which
the external contribution is reasonably an-
ticipated to contribute to developing cost
shared intangibles (the date of a PCT). The
controlled participants are not required to
actually enter into the RT and the compen-
sation due from any controlled participant
will be limited to its RAB share of the
total value of the external contribution, the
scope of which is defined by the RT.
The concept of the RT was devel-
oped in response to arguments that have
been encountered in the examination ex-
perience of the IRS under the existing
regulations. In numerous situations, tax-
payers have purported to convey only
limited availability of resources or ca-
pabilities for purposes of the intangible
development activity (IDA) under a CSA.
An example is a short-term license of an
existing technology. Under the existing
regulations, such cases may, of course,
be examined to assess whether the pur-
ported limitations conform to economic
substance and the parties’ conduct. See
§1.482–1(d)(3)(ii)(B) (Identifying con-
tractual terms). In addition, even if the
short-term license were respected, the con-
tinued availability of the contribution past
the initial license term would require new
license terms to be negotiated taking into
account relevant factors, such as whether
the likelihood of success of the IDA had
materially changed in the interim. The
proposed regulations address the prob-
lems in administering such approaches
more directly by requiring an upfront val-
uation of all external contributions which
would be much more difficult to calculate
if it involved the valuation of a series of
short-term licenses with terms contingent
on such interim changes. Accordingly,
the proposed regulations assume a refer-
ence transaction that does not allow for
contingencies based on the expiration of
short-term licenses that might require fur-
ther renegotiation of the compensation for
the external contribution. No inference is
intended concerning the outcome of such
limitations under the existing regulations.
Thus, for example, consider a CSA
for the development of future generations
of an existing technology owned by one
controlled participant. The PCT compen-
sation obligation of the other controlled
participant or participants would be deter-
mined by reference to the RT consisting
of the transfer of all rights to the existing
technology apart from the rights to exploit
the existing technology without further
development (see section of Preamble be-
low regarding §1.482–7(c) (Make-or-sell
rights excluded)). The rights transferred
in the RT would include the exclusive
right to use the technology for purposes
of research. They would also include the
right to exploit any resulting products
that incorporated the technology and any
resulting products the development of
which is otherwise assisted by the tech-
nology. Moreover, the rights transferred
in the RT would cover a term extending
as long as the exploitation of future gen-
erations of the technology continued. The
RT provides the basis for selection and
application of the method used to value
the compensation owed under the PCT
by each other controlled participant. The
compensation obligation is limited to each
such other controlled participant’s RAB
share of the total value of the rights in the
existing technology that would have been
transferred in the RT.
Issues have arisen regarding whether
an existing research team in place consti-
tutes intangible property for which com-
pensation is due, in addition to sharing
the ongoing compensation and other costs
of maintaining such team, for purposes
of the buy-in provisions under the exist-
ing regulations. The Treasury Department
and the IRS believe that the proper arm’s
length treatment is to include the obliga-
tion to compensate such external contri-
butions of in-place research capabilities in
PCTs. At arm’s length, an uncontrolled
taxpayer seeking to invest in a research
project involving the experienced in-place
researchers would require a commitment
of the experienced team in place for pur-
poses of the project, rather than assum-
ing the risks presented by an inexperienced
team. The Treasury Department and the
IRS believe that a contribution of such
an experienced team in place would re-
sult in the contribution of intangible prop-
erty within the meaning of §1.482–4(b)
and section 936(h)(3)(B).
The proposed regulations, however, do
not restrict the type of transaction that may
be the subject of the RT. An RT may con-
sist of the provision of services as well as
the transfer of intangible property. For ex-
ample, in the case of an experienced re-
October 3, 20056292005–40 I.R.B.

search team in place, therefore, the RT
could be the services agreement to commit
the team to the research project under the
CSA.
Under the proposed regulations, the
controlled participants may designate the
type of transaction involved in the RT, if
different economically equivalent types
of RTs are possible with respect to the
relevant resource or capability. If the con-
trolled participants fail to make such a
designation, the Commissioner may do so.
Exacting compensation for an external
contribution pursuant to a PCT is dis-
tinguishable from charging for another’s
business opportunity. Any taxpayer, con-
trolled or uncontrolled, is free to undertake
the business opportunity of trying to de-
velop an intangible on its own. In that
case, the taxpayer is bearing all costs and
risks, and has no obligation to compensate
anyone for taking free advantage of the
opportunity. Where, however, the ben-
efit of existing resources or capabilities
belonging to another are desired that are
reasonably anticipated to contribute to the
development effort, then, at arm’s length,
the supplier of such resources or capa-
bilities would not contribute them absent
appropriate compensation.
d. Form of PCT Payment and Post
Formation Acquisitions — Proposed
§1.482–7(b)(3)(v) and (vi)
Under the proposed regulations, the
general rule is that the consideration ow-
ing pursuant to a PCT for an external con-
tribution, referred to as thePCT Payments,
may take the form of fixed payments, pay-
ments contingent on the exploitation of the
cost shared intangibles, or a combination
of both. The selected payment form must
be specified no later than the date of the
PCT. The payor of PCT Payments is re-
ferred to as thePCT Payor, and the payee
is referred to as thePCT Payee.
In the case of resources or capabili-
ties developed, maintained, or acquired
prior to the time they are reasonably con-
cluded to contribute to developing cost
shared intangibles (for example, resources
or capabilities that predate the CSA), the
controlled participants have the flexibil-
ity to structure PCT Payments in any
of the available forms, subject to con-
forming to contractual terms, economic
substance, and the parties’ conduct. See
§1.482–1(d)(3)(ii)(B) (Identifying con-
tractual terms). A CSA generally con-
templates that the participants undertake
costs and risks in parallel and in propor-
tion to their RAB shares, but this result
cannot be achieved in the case of exter-
nal contributions that are the product of
previously incurred costs and risks. So,
for such resources orcapabilities, the pro-
posed regulations allow the controlled
participants to provide for the applicable
payment form by the date of the PCT.
A post formation acquisition (PFA) is
an external contribution representing re-
sources or capabilities acquired by a con-
trolled participant inan uncontrolled trans-
action that takes place after formation of
the CSA and that, as of the date of the
acquisition, are reasonably anticipated to
contribute to developing cost shared intan-
gibles. Resources or capabilities may be
acquired in a PFA either directly or indi-
rectly through the acquisitionofaninterest
in an entity or tier of entities.
The Treasury Department and the IRS
believe that the form of PCT Payments for
PFAs must be consistent with the principle
that allocations of cost and risk among
controlled participants after a CSA has
commenced should be in proportion to
their respective RAB shares. Accordingly,
the proposed regulations provide that the
consideration under a PCT for a PFA must
follow the form of payment in the uncon-
trolledtransactioninwhichthePFAwas
acquired. For example, if subsequent to
the formation of a CSA one controlled
participant makes a stock acquisition of
a target the assets of which consist of
resources and capabilities reasonably an-
ticipated as of the date of the acquisition
to contribute to developing cost shared in-
tangibles, the PCT Payment by each other
controlled participant must be in a lump
sum. To avoid the possibility that any pay-
ments are inappropriately characterized by
the participants, neither PCT Payments,
nor cost sharing payments, may be paid in
shares of stock in the payor.
e. Territorial Division of Interests —
Proposed §1.482–7(b)(4)
Controlled participants in a CSA own
interests in the cost shared intangibles and
are able to exploit those intangibles with-
out any obligation to compensate other
participants (other than pursuant to CSTs
or PCTs). Controlled participants must
share intangible development costs in pro-
portion to their reasonably anticipated ben-
efits from their individual exploitation of
such interests. Taxpayers have entered
into cost sharing arrangements in which
the controlled participants receive nonex-
clusive, indivisible worldwide interests in
cost shared intangibles. Taxpayers have
taken the position under the existing regu-
lations that such interests are susceptible to
being individually exploited, and that the
participants’ respective shares of benefits
from such exploitation are susceptible to
being reasonably estimated.
The proposed regulations require that
controlled participants receive non-over-
lapping territorial interests in the cost
shared intangibles that in the aggregate
utilize all the available territories world-
wide. The proposed regulations also
require that a controlled participant be
entitled to the perpetual and exclusive
right to cost shared intangible profits of
any other controlled taxpayer in the same
controlled group as the participant from
transactions with uncontrolled taxpayers
regarding property or services for use,
consumption, or disposition within the
participant’s territory or territories. For
example, where one controlled participant
sells part of its output into a territory be-
longing to another controlled participant,
the former must pay the latter participant
arm’s length compensation to ensure that
the intangible profit on the sale is realized
by the latter participant. These territori-
ality requirements facilitate the ability to
individually exploit,and estimate the rea-
sonably anticipated benefits from individ-
ual exploitation of, interests in cost shared
intangibles. No inference is intended as to
the permissibility of nonexclusive inter-
ests under the existing regulations.
Comments are requested concerning
whether alternativesshould be provided
to territorial division of interests in cost
shared intangibles. Proposed alterna-
tives should further the goal of dividing
the universe of interests into exclusive,
non-overlapping segments to promote
measurability of anticipated benefits and
administrability both by taxpayers and the
IRS. Comments are also requested about
how to facilitate attribution of sales to
territories, or other non-overlapping divi-
sions of interests, such as in the case of
sales via electronic commerce. Comments
2005–40 I.R.B.630October 3, 2005

are also requested on the division, territori-
ally or otherwise, of interests in exploiting
cost shared intangibles in space.
f. CSAs in Substance or Form —
Proposed §1.482–7(b)(5)
Pursuant to proposed §1.482–7(b)
(5)(i), as under the existing regulations,
the Commissioner may, consistently with
§1.482–1(d)(3)(ii)(B) (Identifying con-
tractual terms), apply the §1.482–7 rules
to any arrangement that in substance con-
stitutes a CSA in accordance with the three
substantive requirements enumerated in
proposed §1.482–7(b)(1)(i) through (iii),
notwithstanding a failure otherwise to
meet the §1.482–7 requirements.
Provided a taxpayer has followed the
formal requirements enumerated in pro-
posed §1.482–7(b)(1)(iv) through (vii), the
Commissioner must treat the arrangement
as a CSA if the taxpayer reasonably con-
cluded the arrangement to be a CSA. The
Commissioner may also treat any other ar-
rangement as a CSA, if the taxpayer has
followed such formal requirements.
3. Exclusion of make-or-sell rights —
proposed §1.482–7(c)
Disputes have arisen under the existing
regulations regarding the buy-in related to
a CSA to develop future generations of an
intangible that is being exploited in its then
current version by the PCT Payee. For ex-
ample, there may be licenses of the current
generation intangible to uncontrolled tax-
payers, perhaps with certain rights to make
adaptations for their customers. Taxpay-
ers have asserted that a make-and-sell li-
cense of this type satisfies the requirement
for a buy-in in the CSA under the current
regulations. Such a position misconstrues
the existing regulations, which focus the
buy-in on the availability of the pre-exist-
ing intangibles “for purposes of research in
the intangible development area” under the
CSA. See §1.482–7(g)(2).
The proposed regulations expressly ex-
clude from the scope of a CSA any pro-
vision to the extent it relates to exploit-
ing an existing intangible without further
development, such as the right to make
or sell existing products. The proposed
regulations do, however, allow the aggre-
gate valuation of controlled transactions
relating to make-or-sell rights with PCT
Payments, where such aggregate evalua-
tion provides a more reliable measure of
an arm’s length result than a separate val-
uation of the transactions. See proposed
§1.482–7(g)(2)(v).
4. Intangible development costs —
proposed §1.482–7(d)
The proposed regulations restate the
provisions defining intangible develop-
ment costs orIDCsthat are shared pur-
suant to CSTs under a CSA to coordinate
with the conceptual framework of the pro-
posed regulations and with the stock-based
compensation provisions added in 2003.
As discussed, CSTs and PCTs are the
two major groupings of transactions en-
teredintopursuanttoaCSA.InCSTs,the
controlled participants shareallongoing
costs of developing intangibles. In con-
trast, in PCTs they compensate one an-
other for resources or capabilities devel-
oped, maintained, or acquired externally
to the CSA (whether prior to or during the
course of the CSA). It is necessary to de-
fine IDCs shared in CSTs in a comprehen-
sive manner that does not overlap with the
definition of external contributions com-
pensated in PCTs.
The proposed regulations, accordingly,
define IDCs as all costs, in cash or in kind
(including stock-based compensation), but
excluding costs for land and depreciable
property, in the ordinary course of business
after the formation of a CSA that, based
on analysis of the facts and circumstances,
are directly identified with, or are reason-
ably allocable to, the IDA. The IDA re-
places the concept of theintangible de-
velopment areaunder the existing regu-
lations. The self-contained IDC defini-
tion eliminates the need for the cross-ref-
erence to operating expenses as defined in
§1.482–5(d)(3) of the existing regulations
and thus eliminates potential disputes over
the interaction of these sections.
The proposed regulations also avoid
overlapping definitions of IDCs and ex-
ternal contributions. IDCs are limited to
costs in the ordinary course of business
incurred after the formation of a CSA
and that are directly identified with, or
reasonably allocable to, the IDA. Thus,
for example, the expected value over and
above ongoing compensation and other
costs of an experienced research team
would be compensated by PCTs, but the
ongoing compensation and other costs of
the team attributable to the IDA would be
IDCs shared in CSTs. Moreover, costs for
depreciable property, which under section
197(f)(7) would include amortization of
any amortizable section 197 intangible,
are carved out from IDCs. Instead, to the
extent such intangibles are reasonably an-
ticipated to contribute to developing cost
shared intangibles, they would be com-
pensated in PCTs.
Land and depreciable tangible property
(for example, use of a laboratory facility)
would represent an external contribution.
The proposed regulations, however, con-
tinue the practical approach of the exist-
ing regulations of treating the arm’s length
rental charge under §1.482–2(c) (Use of
tangible property) for such land and depre-
ciable tangible property as IDCs, since typ-
ically these items can be readily valued.
In line with the direction in the 1986
legislative history to reflect “the actual
economic activity” undertaken pursuant
to a CSA, the proposed regulations ex-
pressly provide that generally accepted
accounting principles or federal income
tax accounting rules may provide a useful
starting point, but will not be conclusive
regarding inclusion of costs in IDCs. As
under the existing regulations, IDCs ex-
clude interest expense, foreign income
taxes, and domestic income taxes.
The balance of the proposed regulations
restate the existing regulations with con-
forming changes in light of the new termi-
nology and framework. Technical amend-
ments were made to the special transition
rule on time and manner of making the
election with respect to certain stock-based
compensation and the consistency rules for
measurement and timing with respect to
such stock-based compensation.
Except for such technical amendments,
these proposed regulations incorporate the
existing provisions relating to the elective
method of measurement and timing per-
mitted with respect to certain options on
publicly traded stock. However, the Trea-
sury Department and the IRS are consid-
ering extending availability of the elective
method to other forms of publicly traded
stock-based compensation. The Treasury
Department and the IRS request comments
on which forms of publicly traded stock-
based compensation should be eligible for
the elective method.

5. Reasonably anticipated benefits share
(RAB Share) — proposed §1.482–7(e)
Proposed §1.482–7(e) restates exist-
ing §1.482–7(f)(3)(i) through (iv)(A)
with some technical clarifications and
changes to conform to the new termi-
nology and framework. The proposed
regulations provide, as is implicit in exist-
ing §1.482–7(b)(3), (e)(2), and (f)(3), that
for purposes of determining RAB shares
at any given time, reasonably anticipated
benefits must be estimated over the entire
period, past and future, of exploitation
of the cost shared intangibles, and must
reflect appropriate updates to take into
account the most current reliable data re-
garding past and projected future results
as is available at such time.
6. Changes in participation under a CSA
— proposed §1.482–7(f)
Proposed §1.482–7(f) replaces exist-
ing §1.482–7(g)(3) and (4), as well as
the third and fourth sentences of existing
§1.482–7(g)(1). This provision clarifies
the application of the rules of §1.482–7
in the event of a change in participation
under a CSA. A change in participation
includes the transfer between controlled
participants of all or part of a participant’s
territorial rights coupled with the assump-
tion by the transferee of the associated
obligations under the CSA, the entry into
a CSA of a new controlled participant that
acquires any territorial rights and associ-
ated obligations under the CSA, and the
withdrawal of a controlled participant or
other relinquishment or abandonment of
territorial rights and associated obligations
under the CSA. In the event of a change in
participation, the transferee of the territo-
rial rights and associated obligations under
the CSA succeeds to the transferor’s prior
history under the CSA, including IDCs
borne, benefits derived, and compensation
expenditures pursuant to any PCTs. The
transferor must receive an arm’s length
amount of consideration from the trans-
feree under the rules of §§1.482–1 and
1.482–4 through 1.482–6.
Proposed §1.482–7(e)(2)(i) provides
that in the case of transfers of cost shared
intangibles between controlled partici-
pants, other than by way of a change
in participation described in proposed
§1.482–7(f), the transferor’s benefits for
purposes of RAB share determination are
measured on a look-through basis with
reference to the transferee’s benefits, dis-
regarding any consideration paid by the
transferee (such as a royalty pursuant to a
license agreement).
C. Supplemental Guidance on Methods
Applicable to PCTs
The Treasury Department and the IRS
recognize that taxpayers and the IRS
need additional guidance on the appro-
priate methods for valuation of external
contributions to a CSA. A typical chal-
lenge to valuing nonroutine intangibles
is the uncertainty as to the profitability
of their exploitation. In the case of a
CSA, however, there is also the uncer-
tainty whether and to what extent any
intangible will be successfully developed
under the CSA. Accordingly, proposed
§1.482–7(g) provides supplemental guid-
ance on evaluating external contributions
compensated by PCTs, including general
principles for specified and unspecified
methods, guidance on the application of
existing specified methods, and new spec-
ified methods.
The investor model informs the guid-
ance on valuation. The guidance generally
aims at valuation of the amount charged in
a PCT such that a controlled participant’s
aggregate net investment in a CSA attrib-
utable to cost contributions and external
contributions may be expected to earn a
return appropriate to the riskiness of the
CSA.
1. General rule — proposed
§1.482–7(g)(1)
As discussed, PCTs are one of two ma-
jor categories of transactions (the other be-
ingCSTs)enteredintopursuanttoaCSA.
In PCTs, the controlled participants com-
pensate one another for their respective ex-
ternal contributions that they bring into a
CSA, that is, the resources or capabilities
they have developed, maintained, or ac-
quired externally to (whether prior to or
duringthecourseof)theCSAthatarerea-
sonably anticipated to contribute to devel-
oping cost shared intangibles.
Pursuant to §1.482–1(b)(2), different
sections of the section 482 regulations
apply to different types of transactions,
such as transfers of tangible and intangi-
ble property, services, loans or advances,
and rentals. The method or methods most
appropriate to the calculation of arm’s
length results for controlled transactions
in each category must be selected. When
interrelated controlled transactions are of
different types, the participants, depend-
ing on what produces the most reliable
means of measuring arm’s length results,
may either (1) apply different methods to
the different transactions or (2) aggregate
the transactions for valuation purposes.
See also §1.482–1(f)(2)(i) and proposed
§1.482–7(g)(2)(v) regarding aggregation
of transactions.
A key concept in valuing PCTs is the
RT. The RT is a transaction providing the
benefit of all rights, exclusively and per-
petually, in a resource or capability that
is the subject of the external contribution,
apart from the rights to exploit an existing
intangible without further development. If
in fact, the resource or capability is reason-
ably anticipated to contribute both to de-
veloping or exploiting cost shared intan-
gibles and to other business activities of a
PCT Payee, the proposed regulations pro-
vide that the otherwise applicable value of
the relevant PCT Payments may need to be
prorated between the CSA and any other
business activities on a reasonable basis
that reflects the relative economic values
of the different business activities.
For purposes of the selection of the cat-
egory of method applicable to a controlled
transaction pursuant to §1.482–1(b)(2)(ii),
proposed §1.482–7(b)(3)(iii) provides that
the applicable method used to determine
the compensation for a PCT shall reflect
the type of transaction of the RT. For exam-
ple, in the case of an external contribution
consisting of an in-process intangible, the
RT could be a transfer of intangibles gener-
ally to be evaluated pursuant to §§1.482–1
and 1.482–4 through 1.482–6. As a further
example, in the case of an external con-
tribution consisting of an experienced re-
search team in place, the RT could be the
provision of services generally to be eval-
uated pursuant to §1.482–2(b). If differ-
ent economically equivalent types of RTs
are possible with respect to the relevant re-
source or capability, the controlled partici-
pants may designate the type of transaction
involved in the RT.
Proposed §1.482–7(a)(2) provides that
the arm’s length amount charged in a PCT
must be determined pursuant to the method
or methods applicable to the RT under the
2005–40 I.R.B.632October 3, 2005

relevant provision or provisions of the sec-
tion 482 regulations (as those methods are
supplemented by proposed §1.482–7(g)).
Such method will yield a value for the obli-
gation of each obligor in the PCT (PCT
Payor) consistent with the product of the
combined value to all controlled partici-
pants of the external contribution that is the
subject of the PCT multiplied by the PCT
Payor’s RAB share. Although some speci-
fied and unspecified methods may involve
measuring PCT Payments with reference
to the value of exploiting cost shared in-
tangibles in one or more controlled partic-
ipants’ territories, the application of such
methods must still yield a value that is con-
sistent with the foregoing RAB share of the
total value of the external contribution to
all controlled participants.
Proposed §1.482–7(g) sets forth new
specified methods for purposes of deter-
mining the arm’s length compensation
due under a PCT, namely, the income
method, the acquisition price method, and
the market capitalization method. The
proposed regulations also provide rules
for application of existing specified meth-
ods, such as the comparable uncontrolled
transaction method and the residual profit
method. The proposed regulations also
enunciate general principles governing all
methods, specified and unspecified, for
these purposes. Proposed §1.482–7(g)(1)
provides that each method must be ap-
plied in accordance with the provisions of
§1.482–1, including the best method rule
of §1.482–1(c), the comparability analysis
of §1.482–1(d), and the arm’s length range
of §1.482–1(e), except as those provisions
are modified in §1.482–7(g).
2. General principles — proposed
§1.482–7(g)(2)
a. In General — Proposed
§1.482–7(g)(2)(i)
The proposed regulations provide gen-
eral principles for valuing PCT Payments,
applicable for both specified and unspeci-
fied methods.
b. Valuation Consistent With Upfront
Contractual Terms and Risk Allocations
— Proposed §1.482–7(g)(2)(ii)
Existing §1.482–1(d)(3)(ii) and (iii)
generally provide that contractual terms
and risk allocations are significant factors
in evaluating the most reliable measure of
arm’s length results. The proposed regu-
lations provide for particular contractual
terms and allocations of risk with regard
to PCTs determined no later than the date
of the PCT. See, for example, proposed
§1.482–7(b)(1)(ii), (b)(3), and (k)(1).
Proposed §1.482–7(g)(ii) accordingly re-
iterates the requirement that any method
applied at any time for purposes of valuing
PCT Payments must be consistent with the
applicable contractual terms and alloca-
tion of risk under the CSA and proposed
§1.482–7 as of the date of a PCT, unless
there has been a change in such terms or
allocation made in return for arm’s length
consideration.
It may be particularly important to
maintain consistency with upfront con-
tractual terms and allocation of risk for
CSAs, since PCT Payments may extend
over a period of years. Thus, for exam-
ple, PCT Payments may become due in
subsequent years when actual economic
results may have departed from those
reasonably anticipated as of the date of
the PCT. Subject to the Commissioner’s
ability to make periodic adjustments (see
proposed §1.482–7(i)(6)), the method for
determining the PCT Payments due in the
subsequent year must remain consistent
with the contractual terms and allocation
of risks as of the date of the PCT. Cost
sharing participants, like unrelated in-
vestors, are held to the terms of their deal
at the outset of the investment. For exam-
ple, under the proposed income method,
this upfront contractual-risk consistency
principle is illustrated by the use of the
applicable rate on sales or profits deter-
mined as of the date of the PCT. Thus,
while actual sales or profits may depart
from projections, the upfront risk alloca-
tion continues to be respected by use of the
applicable rate determined as of the date
of the PCT. Note, while a taxpayer may
defend the amount of its PCT Payment in a
subsequent year as arm’s length based on
a different method than that applied in ear-
lieryears,itmayonlydosototheextent
the other method also satisfies the upfront
contractual-risk consistency principle.
Proposed §1.482–7(b)(3)(vi) provides
that the form of payment for a PCT must
be specified no later than the date of the
PCT. The form of payment of a PCT, that
is, fixed and/or contingent payments, in-
volves an allocation of risk among the con-
trolled participants. In the case of PCT
Payments regarding a PFA, the form of
payment in the uncontrolled acquisition
must be followed. However, in the case
of other PCT Payments, the taxpayer has
flexibility in the choice of form, subject to
economic substance and the parties’ con-
duct.
As the result of the upfront contrac-
tual-risk consistency principle, it will
be possible for the taxpayer to compute
a present value, as of the date of the
PCT, of the total arm’s length amount
of all PCT Payments. Under the CSA
documentation requirements in proposed
§1.482–7(k)(2)(ii)(J)(6) and (k)(2)(iii)(B),
the taxpayer is required to maintain doc-
umentation of such upfront valuation and
produce it to the IRS within 30 days of a
request.
c. Projections — Proposed
§1.482–7(g)(2)(iii)
Since PCT Payments often extend over
a period of years and may be contingent on
items (for example, sales, costs, and oper-
ating profit) in such future periods, the val-
uation method, specified or unspecified,
may rely on projections of such items. The
reliability of the valuation method will in
such cases depend on the reliability of such
projections. The proposed regulations pro-
vide that, for these purposes, projections
that have been prepared for non-tax pur-
poses are generally more reliable than pro-
jections that have been prepared solely for
purposes of PCT Payment valuations.
d. Realistic Alternatives — Proposed
§1.482–7(g)(2)(iv)
Regardless of the method or meth-
ods used, evaluation of the arm’s length
charge for a PCT should take into account
the general principle that uncontrolled
taxpayers dealing at arm’s length would
evaluate the terms of a transaction, and
would enter into a particular transaction
only if none of the alternatives is prefer-
able. See §1.482–1(d)(3)(iv)(H) (The
alternatives realistically available to the
buyer and seller). Based on that principle,
PCT valuations would not meet the fore-
going condition where, for any controlled
participant, the total anticipated value, as
of the date of the PCT, is less than the total
anticipated value that could have been
achieved through a realistically available
October 3, 20056332005–40 I.R.B.

alternative investment (whether it is an al-
ternative arrangement for the development
of the cost shared intangibles or an alterna-
tive with a similar risk profile to the CSA).
In other words, a controlled participant,
like any rational investor, would not enter
into an investment when a better alterna-
tive investment is available. Examples are
provided illustrating the application of the
realistic alternativesprinciple in the CSA
context.
e. Aggregation of Transactions —
Proposed §1.482–7(g)(2)(v)
The proposed regulations provide that
multiple PCTs, or one or more PCTs and
one or more transactions not governed by
proposed §1.482–7 (such as a make-or-sell
license excluded from CSA coverage by
proposed §1.482–7(c)), may be aggregated
for purposes of valuation, subject to con-
sideration of whether such aggregate val-
uation yields a more reliable measure of
an arm’s length result than would sepa-
rate valuations. See also §1.482–1(f)(2)(i)
(Aggregation of transactions). For exam-
ple, assume the CSA involves a PCT for
an external contribution of an existing in-
tangible for purposes of developing future
generations of the intangible. Also assume
that there is a license to the other con-
trolled participants of make-and-sell rights
with respect to the current generation of
the intangible. The reliability of an aggre-
gate analysis of the PCT and the license
will be affected by the degree to which the
relative current exploitation benefits from
the existing intangible of the controlled
participants may be expected to match up
with the RAB shares regarding exploita-
tion of the future generations of the in-
tangible. Though it will not generally be
necessary to allocate a reliable aggregate
arm’s length charge as between the vari-
ous transactions, in certain cases such an
allocation may be necessary, for example,
in applying the periodic adjustment rules
in proposed §1.482–7(i)(6).
f. Discount Rate — Proposed
§1.482–7(g)(2)(vi)
Specified and unspecified methods for
valuing PCT Payments may involve con-
verting future or past monetary sums into a
present value as of thedateofaPCT.The
proposed regulations recognize that there
may be different risks and, hence, differ-
ent discount rates associated with different
activities undertaken by a taxpayer. Con-
sistent with the investor model, for items
relating to a CSA, the discount rate em-
ployed should be that which most appro-
priately reflects, as of the date of the PCT,
the risks of development and exploitation
of the intangibles anticipatedtoresultfrom
the CSA. In other words, this follows the
approach that unrelated investors would
take to making an ex ante evaluation of
a prospective investment. Namely, the
expected value of the investment would
equal the projected future cash flows dis-
counted using a discount rate that appro-
priately reflects theanticipated level of
risk being undertaken.
The proposed regulations enumerate
several possibilities for choosing an ap-
propriate discount rate. Where there are
publicly traded entities that would be com-
parables dedicated to similar development
and exploitation activities, their weighted
average cost of capital (WACC) may pro-
vide a reliable basis for derivation of an
appropriate discount rate. Or, if the tax-
payer’s group’s activities are dedicated
to development and exploitation of the
contemplated cost shared intangibles, then
the taxpayer’s own WACC may provide
a reliable basis for derivation of an ap-
propriate discount rate. In other cases,
depending upon the facts and circum-
stances, a taxpayer’s internal hurdle rate
for investments having a comparable risk
profile may provide a reliable basis for
derivation of an appropriate discount rate.
g. Accounting Principles — Proposed
§1.482–7(g)(2)(vii)
The proposed regulations provide that,
while allocations and valuations for ac-
counting purposes may provide a useful
starting point, they will not be determina-
tive of PCT Payments to the extent that the
accounting treatment is not consistent with
economic value. For example, with re-
spect to an acquisition of a target business
consisting of wanted assets (that are rea-
sonably anticipated to contribute to devel-
oping cost shared intangibles) and of un-
wanted assets (that will be abandoned im-
mediately after the acquisition), an alloca-
tion of a portion of the acquisition price
to the abandoned assets done for account-
ing purposes, under the proposed regula-
tions, would not prevent the proper alloca-
tion of the entire acquisition price, in line
with economic reality, to the wanted as-
sets for purposes of PCT Payment valua-
tion. Similarly, with respect to an acqui-
sition of a target business consisting only
of an in-process intangible and an expe-
rienced research team in place, an alloca-
tion of a portion of the acquisition price to
“goodwill” for accounting purposes would
not, under the proposed regulations, pre-
vent the proper allocation of the entire ac-
quisition price, in line with the economic
reality, to the in-process intangible and ex-
perienced research team in place for pur-
poses of PCT Payment valuation. On the
other hand, if the target conducts an operat-
ing business with exploitation already at an
advanced stage of the current generation of
the intangible to be further developed un-
der the CSA, then an accounting allocation
to goodwill may suggest the need for fur-
ther consideration of the reliability of an
acquisition price method for valuing an ex-
ternal contribution whose value excluded
the value of such existing goodwill.
h. Valuation Consistent With the Investor
Model — Proposed §1.482–7(g)(2)(viii)
As has been discussed, the proposed
regulations require that PCT valuations
be consistent with an investor model for
cost sharing. Under the investor model,
the amount charged in a PCT must be
consistent with the assumption that each
controlled participant is making a net ag-
gregate investment, as of the date of a PCT,
attributable to both external contributions
and cost contributions, for purposes of
achieving an anticipated return appropri-
ate to the risks of the CSA over the entire
term of development and exploitation of
the intangibles resulting from the CSA.
The investor model is based on two key
principles regarding PCT valuations. The
first principle is that, ex ante, the aggregate
investment in an IDA would be expected
to yield a rate of return equal to the ap-
propriate discount rate for the CSA. If the
anticipated rate of return exceeds the ap-
propriate discount rate for the CSA, either
anticipated profits have been overstated or
the amount of investment has been under-
stated. If the projections of IDCs and prof-
its are reliable, then the implication could
be that the portion of the investment attrib-
utable to external contributions has been
2005–40 I.R.B.634October 3, 2005

undervalued. Thus, a valuation method for
PCTs is less likely to be reliable if it re-
sults in a rate of return to any controlled
participant’s aggregate investment that is
not equal to the appropriate discount rate
for the CSA.
The second principle is that, ex ante, the
appropriate return to the aggregate invest-
ment in an IDA is measured over the en-
tire period of development and exploita-
tion of cost shared intangibles. Included
in this principle is the concept that no part
of the investment should be viewed as sep-
arately earning a return over a more lim-
ited period. As a general matter, successful
completion of each step in a research pro-
gram is a necessary condition for the com-
pletion of the program as a whole and its
contribution continues over the entire life
of the project. As an example, a project to
develop a new commercial aircraft would
not be considered successfully completed
if all parts of the aircraft had been designed
except the tail assembly. Neither does the
fact that the tail assembly is completed last
imply that its usefulness in the manufac-
ture and sale of aircraft extends beyond the
usefulness of any components completed
earlier in the design process. Each step of
the project continues to have value as long
as the aircraft continues to be built and
used. For this reason, each aspect of the
research program must be viewed as con-
tributing to the success of the program as
a whole (and not just its success for some
limited period of time). Thus, a valuation
methodforPCTsislikelytobelessreli-
able if it assumes a useful life for any con-
tribution to the CSA that does not extend
through the entire anticipated period of de-
velopment and exploitation.
The IRS has examined cases in which
CSAswereenteredintotoutilizecur-
rent generation intangibles as the base
or platform for future generation intangi-
bles, with buy-ins structured as declining
royalties over the limited useful life of
the current generation intangible. The
structure of these buy-ins effectively di-
minishes the value of the buy-in payments,
such that a controlled participant making
the depressed buy-in payments has an
expected return significantly in excess of
the appropriate discount rate for the CSA.
Furthermore, a buy-in based on declining
royalties over a shortened useful life for
the contributed intangibles, on its face, is
not consistent with the principle that the
return to the aggregate investment in an
IDA should be measured over the entire
period of development and exploitation of
cost shared intangibles.
i. Coordination of Best Method Rule
and Form of Payment — Proposed
§1.482–7(g)(2)(ix)
Any method for valuing the amount
charged in a PCT under the proposed reg-
ulations, whether specified or unspecified,
will assume a particular form of payment
(method payment form) for PCT Pay-
ments. For example, as will be discussed,
the proposed income method assumes
contingent payments in the form of an
applicable rate on sales or profits, and the
market capitalization method assumes a
lump sum method payment form. Except
for PCT Payments in respect of PFAs, the
proposed regulations allow taxpayers to
convert the reasonably anticipated present
value, as of the date of the PCT, of the total
arm’s length amount of all PCT Payments
determined under the method payment
form into another form of payment (spec-
ified payment form). For purposes of
the best method rule of §1.482–1(c), the
analysis among competing methods will
be undertaken without regard to whether
their method payment forms corresponds
to the taxpayer’s specified payment form
for PCT Payments. A best method anal-
ysis determines which valuation method
is most reliable from the perspective of
comparability, completeness and accuracy
of the data, and reliability of the underly-
ing assumptions. If the method payment
form of the best method determined under
this analysis differs from the taxpayer’s
specified payment form, then the Commis-
sioner will effect a conversion of the best
method results into the specified payment
form on a reasonable basis, giving due
regard to the taxpayer’s conversion basis
if the taxpayer’s method was determined
to be the best method.
j. Coordination of the Valuations of
Prior and Subsequent PCTs — Proposed
§1.482–7(g)(2)(x)
Cases may arise where, after the date of
one PCT, another PCT is required for other
resources or capabilities of a controlled
participant which only as of a subsequent
date are reasonably anticipated to con-
tribute to the development of cost shared
intangibles and therefore are external con-
tributions only as of such subsequent date.
In such cases where there are PCTs with
different dates, coordination of the valu-
ations of the prior and subsequent PCTs
must be effected pursuant to a method that
provides the most reliable measure of an
arm’s length result.
In some instances the coordination will
be straightforward. As an example, in the
case of a subsequent PCT entered into with
respect to a PFA, the PCT Payments are de-
termined based on the related acquisition,
independent of any prior PCT. For pur-
poses of determining PCT Payments under
a prior PCT, the proposed regulations pro-
vide that the PCT Payments with respect to
the subsequent PCT in this case are treated
the same as unanticipated IDCs. A diver-
gence between actual IDCs and IDCs an-
ticipated on the date of a PCT does not
change the method for determining PCT
Payments with respect to that PCT. Ac-
cordingly, unanticipated payments under a
subsequent PCT entered into with respect
to a PFA will not affect the method for de-
termining PCT Payments in respect of a
prior PCT.
The coordination in other cases will de-
pend on the facts and circumstances. If the
external contributions that were the sub-
jects of the respective prior and subsequent
PCTs were nonroutine contributions, an
approach which may be appropriate would
be to determine PCT Payments both for
the prior and subsequent PCTs going for-
ward from the date of the subsequent PCT
pursuant to a residual profit split method,
as described in proposed §1.482–7(g)(7).
Such application of the residual profit split
method would include as nonroutine con-
tributions all of the following: the exter-
nal contribution(s) that were the subject of
the prior PCT(s), the external contribution
that is the subject of the subsequent PCT,
and the interests of the controlled partici-
pants in the portion of cost shared intangi-
bles in process of development under the
CSA that does not reflect any external con-
tributions.
k. Proration of PCT Payments to the
Extent Allocable to Other Business
Activities — Proposed §1.482–7(g)(2)(xi)
The proposed regulations provide that
the otherwise applicable value of PCT
Payments may need to be prorated be-
October 3, 20056352005–40 I.R.B.

tween the CSA and any other business
activities (other than current make-or-sell
activities) to which the resource or ca-
pability that is the subject of the PCT is
reasonably anticipated to contribute as of
the date of the PCT. A proration will only
be necessary if the method used for valu-
ing the PCT Payment includes the value
of the contribution of the resource or capa-
bility to the other business activities. For
example, an application of the acquisition
price method is based on the full value
of a resource or capability and therefore
includes the value of any contributions
to other business activities, whereas the
CUT and CPM applications of the income
method are based only on the sales or prof-
its of exploiting cost shared intangibles,
and therefore do not include any value of
contributions to other business activities.
For purposes of the best method rule under
§1.482–1(c), the reliability of the analysis
under a method that requires proration is
reduced relative to the reliability of an
analysis under a method that does not re-
quire proration. Any proration must be
done on a reasonable basis that reflects the
relative economic values of the different
business activities.
3. Comparable uncontrolled transaction
(CUT) method — proposed §1.482–7(g)(3)
The comparable uncontrolled trans-
action (CUT) method described in
§1.482–4(c), and the arm’s length charge
described in §1.482–2(b)(3)(first sen-
tence) based on a comparable uncon-
trolled transaction, may be applied to
evaluate whether the amount charged in
a PCT is arm’s length by reference to
the amount charged in a comparable un-
controlled transaction. When applied in
the manner described in §1.482–4(c), or
where a comparable uncontrolled trans-
action provides the most reliable measure
of the arm’s length charge described in
§1.482–2(b)(3)(first sentence), the CUT
method, or the arm’s length charge in the
comparable uncontrolled transaction, will
typically yield an arm’s length total value
for the external contribution that is the
subject of the PCT. That value must then
be multiplied by each PCT Payor’s respec-
tive RAB share in order to determine the
arm’s length PCT Payment due from each
PCT Payor. A territorial CUT may also be
reliably used to the extent the value of the
PCT Payment under the territorial CUT
is consistent with the RAB share of the
worldwide external contribution value.
4. Income method — proposed
§1.482–7(g)(4)
The income method, a new specified
method under the proposed regulations,
follows from the realistic alternatives
principle. The income method determines
PCT Payments in amounts such that the
present value, as of the date of the PCT, to
a controlled participant of entering into a
CSA equals the present value of the PCT
Payee’s best realistic alternative.
The proposed regulations provide two
specific (but nonexclusive) applications of
the income method, one based on the com-
parable uncontrolled transaction (CUT)
method of §1.482–4(c), and the other
based on the comparable profit method
(CPM) of §1.482–5. These applications
may include certain simplifying assump-
tions and are meant to provide examples
of possible applications of the general
income method, not to exclude other pos-
sible applications of this method. Both
applications compute the arm’s length
PCT Payment for each year as the product
of an applicable rate on sales or profit. The
applicable rateis equal to thealternative
rateless thecost contribution adjustment.
The alternative rate represents the rate on
sales or profit which the PCT Payee could
have earned by exploiting cost shared in-
tangibles in the PCT Payor’s territory if the
PCT Payee alone had borne the risks and
costs of developing the cost share intangi-
bles. The CUT application determines the
alternative rate from the perspective of a
licensor as the royalty rate it would have
charged under a license to exploit the cost
shared intangibles in the territory, based
on comparable third party license arrange-
ments. The CPM application determines
the alternative rate from the perspective
of a licensee as the royalty rate it would
have paid such that it earned only a market
return for its routine contributions to the
exploitation of the cost shared intangibles,
based on comparable returns earned by
uncontrolled taxpayers engaged in similar
routine activities. The cost contribution
adjustment is the reduction of the alter-
native rate to reflect the anticipated costs
and risks the PCT Payor will take on by
entering into the CSA.
The income method is typically used
in cases where only one controlled par-
ticipant, namely the PCT Payee, brings
nonroutine contributions into the CSA. In
such circumstances, the other controlled
participant or participants, that is, the PCT
Payors, essentially only commit to bear-
ing their respective shares of anticipated
IDCs and bring only routine contributions
for purposes of exploiting cost shared in-
tangibles. Under the investor model, what
is essentially a routine financing invest-
ment by the PCT Payors in the develop-
ment of intangibles, represented by bear-
ing their share of anticipated IDCs, would
be expected to earn an ex ante rate of
return appropriate to the risks associated
with the CSA and reflected in the discount
rate. The cost contribution adjustment ef-
fectively represents the appropriate return
to that routine financing investment, as of
the date of the PCT, expressed as a rate on
sales or profit.
The use of the applicable rate on sales or
profit, determined as of the date of the PCT
under the income method, also reflects the
principle of consistency with the original
contractual allocation of risk. Thus, while
actual sales may depart from projections,
the upfront risk allocation continues to be
respected by use of the applicable rate de-
termined as of the date of the PCT.
Under the CUT and CPM applications
of the income method, any routine con-
tributions that are external contributions
(routine external contributions) are treated
similarly to cost contributions.
The reliability of the income method
may decrease if more than one controlled
participant brings nonroutine contribu-
tions into the CSA.
5. Acquisition price method — proposed
§1.482–7(g)(5)
The acquisition price method is an ap-
plication of the CUT method pursuant to
§1.482–4(c) and the arm’s length charge
pursuant to §1.482–2(b)(3). This method
ordinarily applies only when substantially
all of the nonroutine resources and capa-
bilities of a recently acquired target’s busi-
ness constitute external contributions, that
is, they are reasonably anticipated to con-
tribute to developing cost shared intangi-
bles. Thus, when these circumstances are
present, this method may be expected to be
2005–40 I.R.B.636October 3, 2005

appropriate for valuing PCT Payments for
PFAs.
Under the acquisition price method, the
arm’s length charge to each PCT Payor
is the product of the adjusted acquisition
price, multiplied by such PCT Payor’s
RAB share. The adjusted acquisition price
seeks to isolate that portion of the acquisi-
tion price of the target business attributable
to the external contributions. The adjusted
acquisition price isequal to the acqui-
sition price of the target, increased by
relevant liabilities, and decreased by the
value of tangible property (separately ac-
counted for under proposed §1.482–7(d))
and by the value of any other resources
and capabilities not covered by PCTs. The
reliability of this method is reduced to
the extent the acquisition price must be
adjusted to take into account significant
difficult-to-value tangible property or re-
sources or capabilities of the target not
covered by a PCT.
6. Market capitalization method —
proposed §1.482–7(g)(6)
The market capitalization method is
also an application of the CUT method pur-
suant to §1.482–4(c) and the arm’s length
charge pursuant to §1.482–2(b)(3). This
method ordinarily applies only when sub-
stantially all of thenonroutine resources
and capabilities of the PCT Payee’s busi-
ness constitute external contributions,
that is, they are reasonably anticipated
to contribute to developing cost shared
intangibles.
Under the market capitalization
method, the arm’s length charge to each
PCT Payor is the product of the adjusted
average market capitalization, multiplied
by such PCT Payor’s RAB share. The
adjusted average market capitalization
seeks to determine that portion of the
market capitalization of the PCT Payee’s
business attributable to the external con-
tributions. The adjusted average market
capitalization is equal to the 60-day (end-
ing on the date of the PCT) average of the
daily market capitalizations of the PCT
Payee, increased by liabilities, and de-
creased by the value of tangible property
(separately accounted for under proposed
§1.482–7(d)) and by the value of any other
resources and capabilities not covered by
PCTs. The daily market capitalization is
calculated on each day the PCT Payee’s
stock is actively traded as the total number
of shares outstanding multiplied by the
stock’s closing price on that day (as ad-
justed, for example, for dividends, stock
splits, and restructurings to the extent such
adjustment can be done reliably). The
reliability of this method is reduced to
the extent the market capitalization must
be adjusted to take into account signifi-
cant difficult-to-value tangible property
or resources or capabilities of the target
notcoveredbyaPCT.Thereliabilityof
this method is also reduced to the extent
the facts and circumstances demonstrate
the likelihood of a material divergence
between the average market capitalization
of the PCT Payee and the value of its re-
sources and capabilities for which reliable
adjustments cannot be made.
7. Residual profit split method —
proposed §1.482–7(g)(7)
The proposed regulations provide
needed guidance on the proper application
of the residual profit split method (RPSM)
of §1.482–6 in the context of the devel-
opment and exploitation of intangibles
pursuant to a CSA. The guidance is nec-
essary in order to implement the general
principles of proposed §1.482–7(g)(2),
such as consistency with the upfront con-
tractual terms and risk allocation under
the CSA and with the investor model.
A purported application of RPSM not in
accordance with this guidance would con-
stitute an unspecified method for purposes
of the sections 482 and 6662(e) and (h)
regulations.
Under the proposed regulations, the
RPSM may not be applied where only one
controlled participant makes significant
nonroutine contributions to the devel-
opment and exploitation of cost shared
intangibles. (An RPSM in such a situ-
ation would be logically equivalent to
the income method using an applicable
rate on profit, and is best considered un-
der that method.) The RPSM divides
operating profit or loss before any ex-
pense or amortization on account of IDCs,
routine external contributions, and non-
routine contributions, from developing
and exploiting cost shared intangibles in
a controlled participant’s territory (territo-
rial operating profit or loss) in three steps.
In the first step of the RPSM, each con-
trolled participant is allocated an amount
of income that is subtracted from its terri-
torial operating profit or loss to provide a
market return to its routine contributions,
other than cost contributions (that is, a con-
trolled participant’s IDCs borne, gross of
cost sharing payments made, and net of
cost sharing payments received).
In the second step of the RPSM, each
controlled participant is allocated a portion
of the residual of its territorial profit or
loss, after the first step allocation, attrib-
utable to its cost contributions. The sec-
ond step cost contribution share is a frac-
tion of such residual operating profit or
loss. The numerator is the present value,
determined as of the date of the PCTs, of
the summation, over the entire period of
developing and exploiting cost shared in-
tangibles, of the total value of the territo-
rial owner’s total anticipated cost contri-
butions. The denominator of the territo-
rial owner’s cost contribution fraction is
the present value, determined as of the date
of the PCTs, of the summation, over the
same period, of the territorial owner’s to-
tal anticipated territorial operating profits,
reduced by a market return for routine con-
tributions (other than cost contributions) to
the relevant business activity in the terri-
tory.
The cost contribution share under the
second step of the RPSM corresponds to
the cost contribution adjustment under the
income method. The cost contribution
share under the RPSM, similar to the cost
contribution adjustment under the income
method, is a reflection of the investor
model. What is essentially a routine fi-
nancing investment in the development of
intangibles by the controlled participants,
represented by bearing their share of an-
ticipated IDCs, would be expected to earn
a return appropriate to the risks associated
with the CSA. The cost contribution share
effectively represents the appropriate re-
turn to that financing investment, as of the
date of the PCTs, expressed as a share of
territorial operating profit or loss.
In the third step of the RPSM, the resid-
ual territorial profit or loss remaining after
the first and second step allocations is di-
vided among all the controlled participants
based on the relative value, as of the date
of the PCTs, of their nonroutine contribu-
tions. The relative value of the nonrou-
tine contributions may be measured with
reference to external benchmarks that re-
flect their fair market value, or with refer-
October 3, 20056372005–40 I.R.B.

ence to estimated capitalized development
costs as appropriately grown or discounted
so that all contributions may be valued on
a comparable dollar base as of the date of
the PCTs.
Any amount of a controlled partici-
pant’s territorial operating profit that is
allocated to another controlled partici-
pant’s nonroutine external contributions
under the third step of the RPSM repre-
sents the amount of the PCT Payment due
to that other controlled participant for its
external contributions.
Under the RPSM, the determinations as
of the date of the PCT of the second step
cost contribution share and the third step
relative nonroutine contribution values
reflect the principle of consistency with
the original contractual allocation of risk.
Thus, while actual territorial operating
profit or loss may depart from projections,
the upfront risk allocation continues to be
respected through the use of the cost con-
tribution shares and relative nonroutine
contribution values determined as of the
date of the PCTs.
In applying the RPSM, any routine con-
tributions that are external contributions
(routine external contributions) are treated
similarly to cost contributions.
The proposed regulations set forth
comparability and reliability considera-
tions appropriate for application of the
RPSM in the CSA context.
8. Unspecified methods — proposed
§1.482–7(g)(8)
The proposed regulations also pro-
vide general rules applicable for methods
not specified in proposed §1.482–7(g)(3)
through (7).
D. Coordination with the Arm’s Length
Standard — Proposed §1.482–7(h)
Transactions in connection with a CSA
must produce results consistent with the
arm’s length standard. The proposed reg-
ulations, therefore, dispel the misconcep-
tion that cost sharing is a safe harbor.
In accordance with §1.482–1(b)(1), the
proposed regulations provide guidance ap-
propriate in the context of a CSA regard-
ing “the results thatwould have been re-
alizedif uncontrolled taxpayershad en-
gagedin the same transaction under the
same circumstances.” (Emphasis added.)
In a CSA where the resulting intangibles
may only be exploited in a controlled par-
ticipant’s territory, the arm’s length result
would require a participant to bear IDCs
only in proportion to the expected relative
values of its territory, that is, in proportion
to its respective RAB shares. The same is
true for PCTs. Where a controlled partici-
pant brings external contributions into the
arrangement, at arm’s length that partici-
pant would only agree to make the external
contributions if it received compensation
from the other participants for the antici-
pated benefits to their respective territories
attributable to the external contributions.
Therefore, the proposed regulations
provide that a CSA, and the CSTs and
PCTs required in connection with a CSA,
produce results thatare consistent with
an arm’s length result within the meaning
of §1.482–1(b) if, and only if, each con-
trolled participant’s IDC share equals its
RAB share, and all other requirements are
satisfied, including those with respect to
PCT Payments.
The Treasury Department and IRS rec-
ognize that a CSA, as defined, represents
only one possible arrangement pursuant
to which parties may choose to share the
costs, risks, and benefits of intangible de-
velopment. Other arrangements, however,
may involve a different division of costs,
risks, and benefits than those arising pur-
suanttoaCSA.Givensuchdifferences,
the guidance under §1.482–7 is not appro-
priate to evaluate what would have been
arm’s length results ofthose other arrange-
ments when undertaken among controlled
taxpayers. As discussed, in such cases the
proposed regulations instead would point
taxpayers to the guidance under the other
provisions of the section 482 regulations
to determine whether such arrangements
achieve arm’s length results.
E. Allocations by the Commissioner
in Connection with CSAs — Proposed
§1.482–7(i)
1. Consolidation of existing allocation
provisions — proposed §1.482–7(i)(1)
through (4)
Proposed §1.482–7(i) assembles in one
section, provisions regarding allocations
by the Commissioner that currently are
spread throughout existing §1.482–7, with
conforming changes to reflect the termi-
nology and framework of the proposed
regulations. Thus, under §1.482–7(i)(1),
the Commissioner is generally authorized
to make allocations to adjust the results of
a controlled transaction in connection with
a CSA so that the results are consistent
with an arm’s length result.
Under proposed §1.482–7(i)(2), the
Commissioner may make appropriate ad-
justments to CSTs to bring IDC shares in
line with RAB shares. Such adjustments
include adding or removing costs from
IDCs, allocating costs between the IDA
and other business activities, improving
the reliability of the benefits measurement
basis used or the projections used to esti-
mate RAB shares, and allocating among
the controlled participants any unallocated
territorial interests in cost shared intangi-
bles. CST adjustments must be reflected
in the year in which the IDCs are incurred,
along with any appropriate allocation of
arm’s length interest to the date of pay-
ment.
Under proposed §1.482–7(i)(3), the
Commissioner may make appropriate
allocations to adjust PCT Payments in
accordance with the proposed regulations.
Thus, the Commissioner may examine
the taxpayer’s method for determining the
amount charged in a PCT in accordance
with the provisions of the section 482
regulations as supplemented by proposed
§1.482–7(g). The Commissioner may ei-
ther propose adjustments to the taxpayer’s
method or apply another method to adjust
the results reported by the taxpayer con-
sistent with an arm’s length result.
Under proposed §1.482–7(i)(4), the
Commissioner may make appropriate allo-
cations regarding changes in participation
in accordance with proposed §1.482–7(f).
2. Allocations when CSTs are consistently
and materially disproportionate to RAB
shares — proposed §1.482–7(i)(5)
The fundamental requirement of a CSA
with regard to CSTs is for the controlled
participants to share IDCs in proportion to
their respective RAB shares. Under pro-
posed §1.482–7(e)(1), RAB shares must
be updated to accountfor changes in eco-
nomic conditions, the business operations
and practices of the participants and the
ongoing development of intangibles. Such
updates must reflect a comprehensive re-
vision over the entire past and projected
2005–40 I.R.B.638October 3, 2005

future period of intangible exploitation in
light of the most current reliable data.
To the extent the controlled partici-
pants consistently and materially fail to
bear IDC shares equal to their respective
RAB shares, the Commissioner would
be able to exercise its authority pursuant
to existing §1.482–1(d)(3)(ii)(B) (Iden-
tifying contractual terms) to impute an
agreement that is consistent with the con-
trolled participants’ course of conduct.
Thus, a participant that bears a dispro-
portionately greater IDC share may be
allocated an undivided interest in another
territory or territories of exploitation of
the cost shared intangibles, and would be
allocated arm’s length consideration from
any other controlled participant whose
IDC share is less than its RAB share over
time.
Current §1.482–7(g)(5) to the extent
it provides that these allocations be “af-
ter any cost allocations authorized by
[§1.482–7(a)(2)]” is eliminated. Some
have interpreted this reference to mean
that the Commissioner must make cost
allocations, and failure to do so would bar
the Commissioner from making an alloca-
tion pursuant to existing §1.482–7(g)(5).
This interpretation, if accepted, defeats
the expectation that controlled partici-
pants must themselves act consistently
with their CST deal and maintain their
RAB shares current for that purpose. No
inference is intended regarding the out-
come under the existing regulations.
3. Periodic adjustments — proposed
§1.482–7(i)(6)
In 1986, Congress indicated a sig-
nificant degree of skepticism about re-
lated-party transfers of high-profit poten-
tial intangibles for relatively insignificant
lump sum or royalty consideration that
effectively place all the intangible devel-
opment downside risk in one controlled
taxpayer and all the upside profit potential
in another. See H.R. Rep. 99–426, at
424–25 (1985). See also Notice 88–123
(the White Paper), 1988–2 C.B. 458,
472–74, 477–480. The legislative history
also notes that it is especially difficult to
obtain realistic comparables with respect
to such intangibles because they seldom
if ever are transferred to unrelated parties.
Seeid.
The Commissioner’s ability to evaluate
controlled participants’ deals with regard
to high-profit potential intangibles is ham-
pered, not only by the absence of compa-
rables, but by an asymmetry of informa-
tion vis-a-vis the taxpayer. The taxpayer
is in the best position to know its busi-
ness and prospects. The Commissioner
faces real challengesin ascertaining the
reliability of the ex ante expectations of
taxpayer’s initial arrangements in light of
significantly different ex post outcomes.
While risk and uncertain outcomes are typ-
ically the hallmarks of high-profit poten-
tial intangibles, significantly different re-
sults raise concernswhether the form of
the initial arrangement matches its sub-
stance. These concerns are particularly
problematic given the information asym-
metry between taxpayers and the IRS. Pe-
riodic adjustments effectively permit the
IRS to impute an arm’s length arrange-
ment that appropriately reflects the profit
potential of transferred intangibles where
the IRS believes that the taxpayers’ ar-
rangement does not appropriately reflect
such profit potential. Because the guid-
ance on periodic adjustments is intended to
address the problem of information asym-
metry, and because it is exceedingly un-
likely that a taxpayer would use informa-
tion asymmetry for anything other than
a tax-advantaged result, periodic adjust-
ments of this type can only be exercised by
the Commissioner.
Accordingly, taxpayers cannot exercise
periodic adjustments of this type. This
prohibition is necessary for proper admin-
istration of these rules. Moreover, taxpay-
ers are not inappropriately disadvantaged
by this rule because they have the ability to
structure their related-party arrangements
in line with the economic prospects of their
business. A taxpayer can always protect it-
self against periodic adjustments by adopt-
ing an arrangement that appropriately re-
flects the profit potential and risks associ-
ated with an intangible transfer, which it is
in the best position to evaluate in an eco-
nomically realistic way. There are various
forms of consideration that taxpayers at
arm’s length might adopt in the face of un-
certainty and risk. In some cases, uncon-
trolled taxpayers might find that projec-
tions of anticipated profits are sufficiently
reliable to fix the pricing for the transac-
tion at the outset on the basis of those pro-
jections. In other cases the uncertainty
in valuing intangible property might lead
them to adopt from the outset contingent
terms of different varieties and degrees
that allow for adjustment in light of actual
profit experience. This does not mean that
the taxpayer must adopt an arrangement
that tilts the risks in a way that necessar-
ily always involves reporting income with-
out regard to later actual results. For ex-
ample, contingent arrangements may ap-
propriately reflect profit potential and yet
appropriately tie in with later outcomes.
In such arrangements, less income may
properly result if the outcomes are less
successful than reasonably anticipated, or
greater income will result if the outcomes
are more successful. Taxpayers simply
are in the best position to structure their
arrangements upfront to accommodate a
range of potential outcomes.
Proposed §1.482–7(j)(6) provides guid-
ance on how periodic adjustments may be
made in the context of a CSA. The goal is
to conform the results of CSTs and PCTs to
the arm’s length standard. In accordance
with the 1986 legislative history, achiev-
ing that goal requires that the “income allo-
cated among the parties reasonably reflect
the actual economic activity undertaken by
each” and that “to the extent, if any, that
one party is actually contributing funds to-
ward research and development at a signif-
icantly earlier point in time than the other,
or is otherwise effectively putting its funds
at risk to a greater extent than the other,it
would be expected that an appropriate re-
turn would be required to such party to re-
flect its investment.” H.R. Conf. Rep. No.
99–841 at II–638 (1986). (Emphasis sup-
plied.)
The proposed regulations build the
CSA periodic adjustment provisions upon
the previously discussed investor model.
The taxpayer’s arrangement will be re-
spected so long as a controlled partici-
pant’s actually experienced return ratio
(AERR), equal to the present value of
its actually experienced operating profits
from exploiting cost shared intangibles
divided by its investment in the CSA
(consisting of the present value sum of
its cost contributions and PCT Payments),
is within a specified periodic return ratio
range (PRRR). The PRRR provides a band
of comfort for actual return ratios of no
more than 2 and no less than
1
/2(unless
there is a failure to substantially comply
with the administrative requirements of
October 3, 20056392005–40 I.R.B.

proposed §1.482–7(k), in which case the
comfort band consists of actual return ra-
tios of no more than 1.5 and no less than
.67). Results above or below these respec-
tive thresholds typically warrant a more
thorough and detailed examination of the
arm’s length nature of the initial taxpayer
arrangement, as well as a means to impute
an alternative arrangement that more re-
liably reflects an arm’s length result, as
described below.
In determining a controlled partici-
pant’s AERR, the present values of its
operating profits and CSA investments are
measured from the period beginning on the
commencement of the CSA through the
end of the year of adjustment. For these
purposes, present values are determined
using an applicable discount rate (ADR)
appropriate to the risks associated with
the given CSA, as the Commissioner may
determine under the guidance of proposed
§1.482–7(g)(2)(vi). Where the stock of
the PCT Payor, or another company that
owns stock in the PCT Payor and is in a
consolidated group with the PCT Payor
for financial accounting purposes, is pub-
licly traded, the Commissioner may treat
the ADR as equal to the publicly traded
company’s weighted average cost of cap-
ital, as determined pursuant to the capital
asset pricing model, subject to the tax-
payer’s ability to show another discount
rate is more appropriate in the facts and
circumstances to the satisfaction of the
Commissioner. Where there is no publicly
traded company in the PCT Payor group,
the ADR will be determined under the
general principles applicable for discount
rates, subject to such adjustments as the
Commissioner determines is appropriate.
In determining the AERR and, thus,
whether the AERR is within or without the
PRRR, it is intended that the items entering
into the computation (e.g., operating prof-
its, cost contributions, and PCT Payments)
are those items as adjusted (including as
the result of any prior IRS adjustments).
The guidance on periodic adjustments
is not intended, for example, to system-
atically reallocate above-market returns
after-the-fact, since such returns may in
whole or in part reward legitimate ex ante
risk-taking by CSA investors. Accord-
ingly, an AERR outside the PRRR does
not necessarily mean that adjustments
will ultimately be warranted. Rather, the
PRRR provides comfort to taxpayers that
within the PRRR they will not be subject
to periodic adjustments. If the AERR
is outside the PRRR, the proposed reg-
ulations provide exceptions pursuant to
which periodic adjustments will not be
made where a taxpayer can demonstrate
that its deal was nevertheless arm’s length.
These exceptions adapt the exceptions in
existing §1.482–4(f)(2)(ii), along with
three additional exceptions appropriate
in the CSA context. One exception ef-
fectively would avoid “start up” triggers
from return ratios below the low end of the
PRRR by delaying low end trigger testing
until after the first five years of substan-
tial exploitation of cost shared intangibles
resulting from the CSA. A similar excep-
tion would enable a taxpayer to avoid a
low end trigger that it can establish to the
satisfaction of the Commissioner results
from the “cut off” from consideration of
anticipated profits, cost contributions, and
PCT Payments beyond the end of the year
of adjustment. For purposes of the fore-
going exception, the taxpayer may assume
that the yearly average of past operating
profits for the years up through the year
of adjustment in which there has been
substantial exploitation of cost shared in-
tangibles will continue into the future.
The third additionalexception would en-
able a taxpayer to avoid a high end trigger
that it can establish to the satisfaction of
the Commissioner results from routine
contributions to its profitability, or from
nonroutine contributions, including its
own external contributions.
In the event that the AERR is outside
the PRRR, and no exception applies, then
the Commissioner may adjust the tax-
payer’s PCT Payments to the level of an
equivalent stream of contingent royalties
as would be determined under a modified
RPSM. The modified RPSM would vary
depending on whether the periodic adjust-
ment was triggered by an AERR above
the high end or below the low end of the
PRRR.
In the event of a trigger above the high
end of the PRRR, the arrangement going
forward beginning with the year of adjust-
ment would effectively treat the past cost
contribution shares of all controlled partic-
ipants as bought out and would determine
new fractions for cost contribution shares
as of the start of the year of adjustment
(if development activity is then continuing
under the CSA). Prior cost contributions
and operating profits, therefore, would not
be taken into account in the second step
of the modified RPSM. The relative valua-
tion of nonroutine contributions, including
external contributions, in the third step of
the modified RPSM would still be deter-
mined as of the original date of the PCTs,
but taking into account any data relevant to
such relative valuation as may be available
up through the date of the periodic adjust-
ment.
In the event of a trigger below the low
end of the PRRR, the arrangement going
forward beginning with the year of ad-
justment would effectively recompute the
original cost contribution share fractions
by substituting projections as revised in
light of actual experience up through the
date of the periodic adjustment.
For these purposes only, the residual
profit split method may be used even
where only one controlled participant
makes significant nonroutine contribu-
tions to the CSA Activity. (As mentioned
above in the discussion of the residual
profit split method, applying the residual
profit split method in such a situation is
logically equivalent to applying the in-
come method using an applicable rate on
profit. For convenience, the proposed
regulations apply the residual profit split
method to all periodic adjustments rather
than separately describing an equivalent
modified income method for the situation
in which only one controlled participant
makes significant nonroutine contribu-
tions to the CSA Activity.) If only one
controlled participant provides all the ex-
ternal contributions and other nonroutine
contributions, then the third step residual
profit or loss belongs entirely to such con-
trolled participant.
It should be emphasized that the Com-
missioner’s determination whether or not
to make periodic adjustments would be
informed by whether the outcome as ad-
justed more reliably reflects an arm’s
length result.
F. Definitions and Special Rules —
Proposed §1.482–7(j)
Proposed §1.482–7(j) provides defini-
tions and special rules relevant to CSAs.
2005–40 I.R.B.640October 3, 2005

1. Controlled participant — proposed
§1.482–7(j)(1)(i)
The proposed regulations incorporate
the existing definitions and examples with
regard to a controlled participant with con-
forming changes to reflect the new frame-
work and terminology. Thus, a controlled
participant is a controlled taxpayer that is
a party to the CSA contractual agreement
that reasonably anticipates that it will de-
rive benefits from exploiting one or more
cost shared intangibles.
The proposed regulations dispense
with the possibility of an uncontrolled
participant in a CSA. The Treasury De-
partment and the IRS are not aware of any
uncontrolled participants in any CSAs.
The elimination of uncontrolled partici-
pants simplified various provisions of the
proposed regulations. The Treasury De-
partment and the IRS request comments in
this regard.
2. Cost shared intangible — proposed
§1.482–7(j)(1)(ii)
The termcost shared intangiblere-
places the termcovered intangiblefrom
existing §1.482–7(b)(4)(iv). A cost shared
intangible means any intangible developed
or to be developed as a result of the IDA.
Thus, cost shared intangibles include both
the intangibles that are contemplated to
result from the IDA as well as any which
serendipitously may result from the IDA.
Cost shared intangibles include any
portion thereof that may be attributable
to an external contribution and, therefore,
do not simply represent the incremental
resultsoftheIDA.Forexample,ifanew
generation software resulting from the
IDA incorporates elements of the prior
generation software, the cost shared in-
tangible is the total result of the prior and
subsequent contributions. No inference
is intended as to the outcome under the
existing regulations.
3. Interest in an intangible — proposed
§1.482–7(j)(1)(iii)
The proposed regulations employ
the same general definition of aninter-
est in an intangiblefound in existing
§1.482–7(a)(2). It should be noted, how-
ever, that the proposed regulations provide
that the interests in cost shared intangi-
bles must be divided among the controlled
participants on a territorial basis. See pro-
posed §1.482–7(b)(1)(i) and (b)(4).
4. Benefits — proposed §1.482–7(j)(1)(iv)
The proposed regulations clarify the
definition ofbenefitsfoundinexisting
§1.482–7(e)(1). Benefits means the sum
of additional revenue generated, plus cost
savings, minus any cost increases from
exploiting cost shared intangibles.
5. Reasonably anticipated benefits —
proposed §1.482–7(j)(1)(v)
The proposed regulations effectively
employ the same definition ofreason-
ably anticipated benefitsfoundinexisting
§1.482–7(e)(2).
6. Territorial operating profit or loss —
proposed §1.482–7(j)(1)(vi)
The proposed regulations defineterri-
torial operating profit or lossas the op-
erating profit or loss as separately earned
by each controlled participant in its geo-
graphic territory from the CSA Activity,
determined before any expense (including
amortization) on account of IDCs, rou-
tine external contributions, and nonroutine
contributions.
7. CSA Activity — proposed
§1.482–7(j)(1)(vii)
The proposed regulations defineCSA
Activityas the activity of developing and
exploiting cost shared intangibles.
8. Consolidated group — proposed
§1.482–7(j)(2)(i)
In line with existing §1.482–7(c)(3), the
proposed regulations treat all members of a
U.S.groupfilingconsolidatedincometax
returns as one taxpayer for purposes of the
CSA provisions. The proposed regulations
would also treat all members of a foreign
fiscal unity as one taxpayer for these pur-
poses.
9. No trade or business and partnership
— proposed §1.482–7(j)(2)(ii) and (iii)
In line with existing §§1.482–7(a)(1)
and 301.7701–1(c), the proposed regula-
tions provide that participation in a CSA,
of itself, does not constitute a U.S. trade or
business or result in the creation of a part-
nership for federal income tax purposes.
10. Character of payments — proposed
§1.482–7(j)(3)
In line with existing §1.482–7(h), the
proposed regulations provide ordering
rules for characterizing cost sharing pay-
ments with regard to the items they re-
imburse. PCT Payments will be charac-
terized consistently with the designation
of the type of transaction involved in the
RT. The proposed regulations continue to
provide for the netting of PCT Payments
made to, and received by, a controlled
participant.
G. Administrative Provisions — Proposed
§1.482–7(k)
The proposed regulations include pro-
visions to facilitate administration of,
and compliance with, the cost sharing
rules. Thus, under a CSA, the con-
trolled participants must substantially
comply with certain contractual, doc-
umentation, accounting, and reporting
requirements. Similar requirements are
spread throughout the existing regulations
in §1.482–7(b), (c)(1), (i), and (j). In the
proposed regulations, the substantial com-
pliance standard is included in proposed
§1.482–7(b)(1)(iv) through (vii), and the
specific requirements are assembled to-
gether in §1.482–7(k).
1. CSA contractual requirements —
proposed §1.482–7(k)(1)
Under proposed §1.482–7(k)(1)(i), a
CSA must be recorded in writing in a
contract that is contemporaneous with
the formation (and any revision) of the
CSA. The written CSA must incorpo-
rate the contractual provisions set forth
in proposed §1.482–7(k)(1)(ii). Proposed
§1.482–7(k)(1)(iii) provides that a written
contractual agreement is contemporane-
ous with the formation (or revision) of a
CSA if, and only if, the controlled partic-
ipants record the CSA, in its entirety, in a
document that they sign and date no later
than 60 days after the first occurrence of
any IDC to which such agreement (or re-
vision) is to apply. By requiring that CSAs
be memorialized contemporaneously with
formation (or revision), the CSA contrac-
tual provisions are morelikelytoreliably
reflect (without hindsight) the relative
risks of the controlled participants.
October 3, 20056412005–40 I.R.B.

2. CSA documentation requirements —
proposed §1.482–7(k)(2)
Under proposed §1.482–7(k)(2)(i), the
controlled participants must timely update
and maintain sufficient documentation to
establish that the participants have met
the contractual requirements of proposed
§1.482–7(k)(1). In addition, the con-
trolled participants must timely update
and maintain documentation sufficient
to establish and support the items listed
in proposed §1.482–7(k)(2)(ii) regarding
the ongoing implementation of the CSA,
CSTs, and PCTs. Thus, each controlled
participant must at timely intervals update
and maintain the documentation required
by proposed §1.482–7(k)(2)(i) and (ii)
on an ongoing basis from the outset of
the formation of the CSA. To the extent
that additional documentation is required
by the new availability of information or
the occurrence of post-formation events,
each controlled participant must maintain
such documentation in a manner such
that the controlled participant retains and
supplements (but does not replace) the
documentation maintained from the out-
set.
Proposed §1.482–7(k)(2)(iii), which
replaces existing §1.482–7(j)(2)(ii), cross-
references proposed §1.6662–6(d)(2)
(iii)(D) for the coordination of the CSA
documentation rules with the specified
method documentation rules under the
section 6662 transfer pricing penalty regu-
lations. Proposed §1.6662–6(d)(2)(iii)(D)
provides that satisfaction of the CSA
documentation requirements satisfies the
specified method principal documentation
requirements with respect to the CSTs
and PCTs, other than the requirements
to provide a description of the relevant
organizational structure and an index of
principal and background documents, pro-
vided that such documentation is sufficient
to establish that the taxpayer reasonably
concluded that its method and application
provided the most reliable measure of an
arm’s length result.Each controlled par-
ticipant must provide such documentation
to the IRS within 30 days of a request, sub-
ject to extension in the Commissioner’s
discretion.
3. CSA accounting requirements —
proposed §1.482–7(k)(3)
Proposed §1.482–7(k)(3)(i) tracks the
existing regulations in requiring that the
controlled participants establish a con-
sistent method of accounting, translate
foreign currencies on a consistent basis,
and explain any material differences from
U.S. generally accepted accounting princi-
ples. Under proposed §1.482–7(k)(3)(ii),
controlled participants may not rely solely
upon financial accounting rules to estab-
lish satisfaction of the accounting require-
ments. Rather, the method of accounting
must clearly reflect income.
4. CSA reporting requirements —
proposed §1.482–7(k)(4)
Proposed §1.482–(7)(k)(4)(i) requires
that each controlled participant must file
with the Ogden Campus a statement re-
garding its participation in a CSA (CSA
Statement). The CSA Statement must
provide the information enumerated in
proposed §1.482–7(k)(4)(ii), including the
earliest date that any IDC occurred, the
date on which the controlled participants
formed (or revised) the CSA, and (if dif-
ferent from the immediately preceding
date) the date on which the controlled par-
ticipants recorded theCSA(orrevision)
in accordance with the contemporaneous
recordation requirement.
Pursuant to proposed §1.482–7(k)(4)
(iii)(A), each controlled participant must
file an original CSA Statement with
the IRS no later than 90 days after the
first occurrence of an IDC to which the
newly-formed CSA applies or, in the case
of a taxpayer that became a controlled
participant after the formation of the CSA,
no later than 90 days after such taxpayer
became a controlled participant. The
CSA Statement must be dated and signed,
under penalties of perjury, by an officer
of the controlled participant who is duly
authorized (under local law) to sign the
statement on behalf of the controlled par-
ticipant.
In addition to the 90-day rule described
above, proposed §1.482–7(k)(4)(iii)(B)
contains an annual reporting requirement.
Each controlled participant must attach to
its U.S. income tax return, for each taxable
year for the duration of the CSA, a copy
of the original CSA Statement that the
controlled participant filed in accordance
with the 90-day rule. Further, the annual
reporting by the controlled participant
must update the information reflected on
the original CSA Statement by attaching a
schedule that documents changes in such
information over time. If a controlled
participant does not file a U.S. income tax
return, then it must ensure that the forego-
ing CSA Statement and updated schedule
are attached to any Schedule M of Form
5471, to any Form 5472, or to any Form
8865 with respect to that participant.
H. Effective Date and Transition Rule —
Proposed §§1.482–7(l) and (m)
The proposed regulations are proposed
to be applicable on the date of publica-
tion of the proposed regulations as a final
regulation in theFederal Register. Thus,
CSAs commencing on or after such date,
and CSTs and PCTs occurring after such
date with respect to CSAs existing as of the
effective date, will be subject to §1.482–7,
as then finally revised. Conversely, other
transactions not reasonably anticipated
to contribute to developing intangibles
pursuant to an arrangement constituting
a CSA described in §1.482–7(b)(1) or
(5) will be subject to other applicable
section 482 regulations. See proposed
§1.482–7(a)(3)(iii).
The proposed regulations provide tran-
sition rules under which an existing ar-
rangement that constituted a qualified cost
sharing arrangement under the regulations
before the effective date will be consid-
ered a CSA and will be allowed an addi-
tional period to conform to the new rules
with certain modifications. Although cer-
tain documentation requirements are de-
layed and certain substantive requirements
concerning pre-effective date matters are
relaxed for a grandfathered CSA described
in the previous sentence, the controlled
participants’ CSTs and PCTs that occur af-
ter the effective date would have to com-
ply with the substantive requirements of
these regulations beginning immediately
after such date. CSTs and PCTs occur-
ring prior to the effective date are subject
to these regulations only in the event that
PCT Payments become subject to periodic
adjustment under paragraph (i)(6) as a re-
sult of a subsequent PCT occurring on or
after the effective date.
2005–40 I.R.B.642October 3, 2005

The proposed regulations specify cir-
cumstances under which the grandfathered
status of pre-effectivedatearrangements
would terminate. Accordingly, an oth-
erwise grandfathered arrangement would
cease to be so grandfathered from the ear-
liest of a failure of the controlled partici-
pants to substantiallycomply with the reg-
ulations as transitionally modified, a ma-
terial change in the scope of the CSA as
contemplated in the underlying contractual
arrangement (such as a material expansion
of the activities undertaken in the CSA be-
yond those undertaken as of the effective
date), or a 50 percent change in the ben-
eficial ownership of the interests in cost
shared intangibles.
I. Changes to Other Provisions
The proposed regulations make
conforming changes to §1.367(a)–1T,
§1.861–17, and §§1.482–1et seq.of the
section 482 regulations to reflect the new
terminology and framework of the CSA
provisions.
The proposed regulations redesignate
current §1.482–7 as §1.482–7A which
would continue to apply for dates prior to
the publication of this document as a final
regulation in theFederal Registerand to
the extent applicable under the transition
rule of proposed §1.482–7(m).
The proposed regulations add examples
to §1.482–8 to illustrate the application of
the best method rule in connection with
the new specified methods under proposed
§1.482–7(g).
As previously stated, proposed
§1.6662–6(d)(2)(iii)(D) coordinates the
CSA documentation requirements of pro-
posed §1.482–7(k)(2) with the specified
method documentation requirements of
the section 6662 transfer pricing penalty
regulations.
In line with the penultimate sen-
tence of existing §1.482–7(a)(1) and
proposed §1.482–7(j)(2)(iii), proposed
§301.7701–1(c) provides that participa-
tion in a CSA, of itself, does not give rise
to a separate entity.
Special Analysis
It has been determined that this notice
of proposed rulemaking is not a significant
regulatory action as defined in Executive
Order 12866. Therefore, a regulatory as-
sessment is not required. It has been deter-
mined also that section 553(b) of the Ad-
ministrative Procedure Act (5 U.S.C. chap-
ter 5) does not apply to these regulations.
It is hereby certified that the collections of
information in these regulations will not
have a significant economic impact on a
substantial number of small entities. This
certification is based on the fact that few
small entities are expected to enter into
cost sharing agreements, as defined herein,
and that for those that do, the burdens im-
posed under proposed §1.482–7(b)(1)(iv)
through (vii) and (k) would be minimal.
Therefore, a Regulatory Flexibility Anal-
ysis under the Regulatory Flexibility Act
(5 U.S.C. chapter 6) is not required. Pur-
suant to section 7805(f), this notice of pro-
posed rulemaking will be submitted to the
Chief Counsel for Advocacy of the Small
Business Administration for comment on
its impact on small business.
Comments and Public Hearing
Before these proposed regulations are
adopted as final regulations, consideration
will be given to any electronic or writ-
ten comments (a signed original and eight
(8) copies) that are submitted timely to the
IRS. The Treasury Department and the IRS
specifically request comments on the clar-
ity of the proposed regulations and how
they may be made easier to understand.
All comments will be available for public
inspection and copying.
A public hearing has been scheduled
for November 16, 2005, at 10 a.m., in
the auditorium, Internal Revenue Build-
ing, 1111 Constitution Avenue, NW, Wash-
ington, DC. Due to building security pro-
cedures, visitors must enter at the Con-
stitution Avenue entrance. In addition,
all visitors must present photo identifica-
tion to enter the building. Because of ac-
cess restrictions, visitors will not be admit-
ted beyond the immediate entrance more
than 30 minutes before the hearing starts.
For information about having your name
placed on the building access list to attend
the hearing, see theFOR FURTHER IN-
FORMATION CONTACTsection of this
preamble.
The rules of 26 CFR 601.601(a)(3) ap-
ply to the hearing. Persons who wish to
present oral comments at the hearing must
submit electronic or written comments and
an outline of the topics to be discussed and
the time to be devoted to each topic (signed
original and eight (8) copies) by October
26, 2005. A period of 10 minutes will be
allotted to each person for making com-
ments.
An agenda showing the scheduling of
the speakers will be prepared after the
deadline for receivingoutlines has passed.
Copies of the agenda will be available free
of charge at the hearing.
Drafting Information
The principal author of these proposed
regulations is Jeffrey L. Parry of the Office
of Chief Counsel (International). How-
ever, other personnel from the Treasury
Department and the IRS participated in
their development.

*****
Par. 8. Section 1.482–7 is revised to
read as follows:
§1.482–7 Methods to determine taxable
income in connection with a cost sharing
arrangement.
(a)In general. The arm’s length
amount charged in a controlled transaction
reasonably anticipated to contribute to
developing intangibles pursuant to a cost
sharing arrangement (CSA), as described
in paragraph (b) of this section, must be
determined under a method described in
this section. Each method must be ap-
plied in accordance with the provisions of
§1.482–1, except as those provisions are
modified in this section.
(1)RAB share method for cost sharing
transactions (CSTs). The controlled par-
ticipants that are parties to a cost sharing
transaction (CST), as described in para-
graph (b)(2) of this section, must share
the intangible development costs (IDCs) of
the cost shared intangibles in proportion to
their shares of reasonably anticipated ben-
efits (RAB shares). See paragraph (j)(1)
of this section for the definitions of con-
trolled participant, cost shared intangible,
benefits, and reasonably anticipated bene-
fits, and paragraphs (d) and (e) of this sec-
tion regarding IDCs and RAB shares, re-
spectively.
(2)Methods for preliminary or con-
temporaneous transactions (PCTs).The
arm’s length amount charged in a pre-
liminary or contemporaneous transaction
(PCT), as described in paragraph (b)(3)
of this section, must be determined under
the method or methods under the other
section or sections of the section 482 regu-
lations, as supplemented by paragraph (g)
of this section, applicable to the reference
transaction (RT) reflected by the PCT. See
§1.482–1(b)(2)(ii) (Selection of category
of method applicable totransaction), para-
graph (b)(3)(iv) of this section (Reference
transaction), and paragraph (g) of this sec-
tion (Supplemental guidance on methods
applicable to PCTs).
(3)Methods for other controlled trans-
actions—(i)Contribution to a CSA by
a controlled taxpayer that is not a con-
trolled participant. If a controlled tax-
payer that is not a controlled participant
contributes to developing the cost shared
intangibles, it must receive consideration
from the other controlled participants un-
der the rules of §1.482–4(f)(3)(iii) (Allo-
cations with respect to assistance provided
to the owner). Such consideration will be
treated as an intangible development cost
for purposes of paragraph (d) of this sec-
tion.
(ii)Transfer of interest in a cost shared
intangible. If at any time (during the term,
or upon or after the termination, of a CSA)
a controlled participant transfers an inter-
est in a cost shared intangible to another
controlled taxpayer, the controlled partici-
pant must receive an arm’s length amount
of consideration from the transferee un-
der the rules of §§1.482–1 and 1.482–4
through 1.482–6.
(iii)Controlled transactions not in con-
nection with a CSA.Thissectiondoesnot
apply to a controlled transaction reason-
ably anticipated to contribute to develop-
ing intangibles pursuant to an arrangement
that is not a CSA described in paragraph
(b)(1) or paragraph (b)(5) of this section.
Whether the results of any such controlled
transaction are consistent with an arm’s
length result must be determined under the
applicable rules of the section 482 regula-
tions without regard to this section. For
example, an arrangement for developing
intangibles in which one controlled tax-
payer’s costs of developing the intangi-
bles significantly exceeds its share of rea-
sonably anticipated benefits from exploit-
ing the developed intangibles would not in
substance be a CSA, as described in para-
graphs (b)(1)(i) through (iii) or paragraph
(b)(5)(i) of this section. In such a case,
unless the rules of this section are appli-
cable by reason of paragraph (b)(5)(ii) of
this section, the arrangement must be an-
alyzed under other applicable sections of
the section 482 regulations to determine
whether it achieves arm’s length results,
and if not, to determine any allocations by
the Commissioner that are consistent with
such other section 482 regulations.
(b)Cost sharing arrangement (CSA)—
(1)In general. A CSA to which the provi-
sions of this section apply is a contractual
agreement to share the costs of developing
one or more intangibles under which the
controlled participants —
(i) At the outset of the arrangement di-
vide among themselves all interests in cost
shared intangibles on a territorial basis as
described in paragraph (b)(4) of this sec-
tion;
(ii) Enter into and effect CSTs covering
all IDCs and PCTs covering all external
contributions, as described in paragraphs
(b)(2) and (b)(3) of this section, for pur-
poses of developing the cost shared intan-
gibles under the CSA;
(iii) As a result, individually own and
exploit their respective interests in the
cost shared intangibles without any further
obligation to compensate one another for
such interests;
(iv) Substantially comply with the
CSA contractual requirements that are de-
scribed in paragraph (k)(1) of this section;
(v) Substantially comply with the CSA
documentation requirements that are de-
scribed in paragraph (k)(2) of this section;
(vi) Substantially comply with the CSA
accounting requirements that are described
in paragraph (k)(3) of this sections; and
(vii) Substantially comply with the
CSA reporting requirements that are de-
scribed in paragraph (k)(4) of this section.
(2)CSTs—(i)In general.CSTsare
controlled transactions between or among
controlled participants in which such par-
ticipants share the IDCs of one or more
cost shared intangibles in proportion to
their respective RAB shares from their in-
dividual exploitation of their interests in
the cost shared intangibles that they ob-
tain under the CSA. Cost sharing payments
may not be paid in shares of stock in the
payor. See paragraphs (b)(4), (d), and (e)
of this section for the rules regarding inter-
ests in cost shared intangibles, IDCs, and
RAB shares, respectively.
2005–40 I.R.B.646October 3, 2005

(ii)Example. The following example
illustrates the principles of this paragraph
(b)(2):
Example. Companies C and D, who are members
of the same controlled group, enter into a CSA that
is described in paragraph (b)(1) of this section. In
the first year of the CSA, C and D conduct the IDA,
as described in paragraph (d)(1) of this section. The
total IDCs in regard to such activity are $3,000,000
of which C and D pay $2,000,000 and $1,000,000,
respectively, directly to third parties. As between C
and D, however, their CSA specifies that they will
share all IDCs in accordance with their RAB shares
(as described in paragraph (e)(1) of this section),
which are 60% for C and 40% for D. It follows that
C should bear $1,800,000 of the total IDCs (60%
of total IDCs of $3,000,000) and D should bear
$1,200,000 of the total IDCs (40% of total IDCs
of $3,000,000). D makes a CST payment to C of
$200,000, that is, the amount by which D’s share of
IDCs in accordance with its RAB share exceeds the
amount of IDCs initially borne by D ($1,200,000 -
$1,000,000), and which also equals the amount by
which the total IDCs initially borne by C exceeds
its share of IDCS in accordance with its RAB share
($2,000,000 - $1,800,000). As a result of D’s CST
payment to C, C and D will bear amounts of to-
tal IDCs in accordance with their respective RAB
shares.
(3)PCTs—(i)In general.APCTisa
controlled transaction in which each other
controlled participant (PCT Payor) is ob-
ligated to compensate a controlled partici-
pant (PCT Payee) for an external contribu-
tion of the PCT Payee.
(ii)External contributions.Anexter-
nal contribution consists of the rights set
forth under the reference transaction (RT)
in any resource or capability that is reason-
ably anticipated to contribute to develop-
ing cost shared intangibles and that a PCT
Payee has developed, maintained, or ac-
quired externally to (whether prior to or
during the course of) the CSA. For pur-
poses of this section, external contribu-
tions do not include rights in depreciable
tangible property or land, and do not in-
clude rights in other resources acquired by
IDCs. See paragraphs (b)(2) and (d)(1) of
this section.
(iii)PCT Payments. The arm’s length
amount of the compensation due under a
PCT (PCT Payment) will be determined
under a method pursuant to paragraphs
(a)(2) and (g) of this section applicable to
the RT, as described in paragraph (b)(3)(iv)
of this section. The applicable method will
yield a value for the compensation obliga-
tion of each PCT Payor consistent with the
product of the combined value to all con-
trolled participants of the external contri-
bution that is the subject of the PCT mul-
tiplied by the PCT Payor’s RAB share.
(iv)Reference transaction (RT).AnRT
is a transaction providing the benefits of
all rights (RT Rights), exclusively and per-
petually, in a resource or capability de-
scribed in paragraph (b)(3)(ii) of this sec-
tion, excluding any rights to exploit an
existing intangible without further devel-
opment. See paragraph (c) of this sec-
tion (Make-or-sell rights excluded). If a
resource or capability is reasonably an-
ticipated to contribute both to develop-
ing or exploiting cost shared intangibles
and to other business activities of the PCT
Payee, other than exploiting an existing in-
tangible without further development, then
the PCT Payment that would otherwise
be determined with reference to the RT
(which generally presumes a provision of
exclusive and perpetual rights) may need
to be prorated as described in paragraph
(g)(2)(xi) of this section. For purposes
of §1.482–1(b)(2)(ii) and paragraph (a)(2)
of this section, the controlled participants
must include the type of transaction in-
volved in the RT as part of the documen-
tation of the RT required under paragraph
(k)(2)(ii)(H) of this section. If different
economically equivalent types of RTs are
possible with respect to the relevant re-
source or capability, the controlled partic-
ipants may designate the type of transac-
tion involved in the RT. If the controlled
participants fail to make this designation
in their documentation, the Commissioner
may make a designation consistent with
the RT and other facts and circumstances.
While the PCT Payee and PCT Payors
must enter into the PCT providing for the
relevant compensation obligation, they are
not required to actually enter into the RT
that is referenced for purposes of deter-
mining the magnitude of the compensation
obligation under the PCT.
(v)PFAs. A post formation acquisition
(PFA) is an external contribution that is ac-
quired by a controlled participant in an un-
controlled transaction that takes place af-
ter the formation of the CSA and that as
of the date of acquisition is reasonably an-
ticipated to contribute to developing cost
shared intangibles. Resources or capabil-
ities may be acquired in a PFA either di-
rectly, or indirectly through the acquisition
of an interest in an entity or tier of entities.
(vi)Form of payment—(A)In general.
The consideration under a PCT for an ex-
ternal contribution other than a PFA may
take one or a combination of both of the
following forms —
(1) Payments of a fixed amount, either
paid in a lump sum payment or in install-
ment payments spread over a specified pe-
riod, with interest calculated in accordance
with §1.482–2(a) (Loans or advances); or
(2) Payments contingent on the ex-
ploitation of cost shared intangibles by the
PCT Payor. The form of payment selected
for any PCT, including the basis and struc-
ture of the payments, must be specified no
later than the date of that PCT.
(B)PFAs. The consideration under a
PCT for a PFA must be paid in the same
form as the uncontrolled transaction in
which the PFA was acquired.
(C)No PCT Payor Stock.PCTPay-
ments may not be paid in shares of stock
in the PCT Payor.
(vii)Date of a PCT. The controlled par-
ticipants must enter into a PCT as of the
earliest date on or after the CSA is entered
into on which the external contribution is
reasonably anticipated to contribute to de-
veloping cost shared intangibles.
(viii)Examples. The following exam-
ples illustrate the principles of this para-
graph (b)(3). In each example, Compa-
nies P and S are members of the same con-
trolled group, and execute a CSA that is
described in paragraph (b)(1) of this sec-
tion. The examples are as follows:
Example 1. Company P has developed and
currently markets version 1.0 of a new software ap-
plication XYZ. Company P and Company S execute
a CSA under which they will share the IDCs for
developing future versions of XYZ. Version 1.0 is
reasonably anticipated to contribute to the develop-
ment of future versions of XYZ and therefore the RT
rights in version 1.0 constitute an external contribu-
tion of Company P for which compensation is due
from Company S pursuant to a PCT. The applicable
method and determination of the arm’s length com-
pensation due pursuant to the PCT will be based on
the RT. The controlled participants designate the RT
as a transfer of intangibles that would otherwise be
governed by §1.482–4, if entered into by controlled
parties. Accordingly, pursuant to paragraph (a)(2) of
this section, the applicable method for determining
the arm’s length value of the compensation obligation
under the PCT between Company P and Company
S will be governed by §1.482–4 as supplemented by
paragraph (g) of this section. The RT in this case is
the perpetual and exclusive provision of the benefit
of all rights in version 1.0, other than the rights de-
scribedinparagraph(c)ofthissection(Make-or-sell
rights excluded). This includes the exclusive right
to use version 1.0 for purposes of research and the
right to exploit any products that incorporated the
platform technology of version 1.0, and would cover
October 3, 20056472005–40 I.R.B.

a term extending as long as the uncontrolled taxpayer
were to continue to exploit future versions of XYZ or
any other product based on the version 1.0 platform.
Though Company P and Company S are not required
to actually enter into the transaction described by
the RT, the value of the compensation obligation of
Company S for the PCT will reflect the full value
of the external contribution defined by the RT, as
limited by Company S’s RAB share.
Example 2. Company P and Company S exe-
cute a CSA under which they will share the IDCs
for developing Vaccine Z. Company P will commit
its research team that has successfully developed a
number of other vaccines to the project. The exper-
tise and existing integration of the research team is
a unique resource or capability of Company P which
is reasonably anticipated to contribute to the devel-
opment of Vaccine Z and therefore the RT Rights in
the research team constitute an external contribution
for which compensation is due from Company S as
part of a PCT. The applicable method and determina-
tion of the arm’s length compensation due pursuant to
thePCTwillbebasedontheRT.Thecontrolledpar-
ties designate the RT as a provision of services that
would otherwise be governed by §1.482–2(b)(3)(first
sentence) if entered into by controlled parties. Ac-
cordingly, pursuant to paragraph (a)(2) of this sec-
tion, the applicable method for determining the arm’s
length value of the compensation obligation under the
PCT between Company P and Company S will be
governed by §1.482–2(b)(3)(first sentence) as sup-
plemented by paragraph (g) of this section. The RT in
this case is the perpetual and exclusive provision of
the benefits by Company P of its research team to the
development of Vaccine Z by the uncontrolled party.
Because the IDCs include the ongoing compensation
of the researchers, the compensation obligation under
the PCT is only for the value of the commitment of
the research team by Company P to the CSA’s devel-
opment efforts net of such researcher compensation.
Though Company P and Company S are not required
to actually enter into the transaction described by the
RT, the value of the compensation obligation of Com-
pany S for the PCT will reflect the full value of pro-
vision of services described in the RT, as limited by
Company S’s RAB share.
Example 3. In Year 1, Company P and Com-
pany S execute a CSA under which they will share
the IDCs for developing Product X. In Year 3, Com-
pany P acquires technology intangibles that it antici-
pates will contribute to the development of Product X
from an uncontrolled party for a lump sum considera-
tion. Because the technology intangibles are reason-
ably anticipated to contribute to the development on
the date of the acquisition and the acquisition is an un-
controlled transaction that takes place after the forma-
tion of the CSA, the RT Rights in the technology in-
tangibles are an external contribution acquired as part
of a PFA. Accordingly, Company P and Company S
must enter into a PCT in which Company S compen-
sates Company P for the RT Rights in the technology
intangibles and pursuant to paragraph (b)(3)(vi)(B) of
this section, the form of payment of the PCT must
mirror the lump sum form of payment of the PFA.
Example 4. Assume the same facts as inExam-
ple 3. In Year 4, Company P acquires Company X
in a tax-free stock-for-stock acquisition. Company
X is a start-up technology company with negligible
amounts of tangible property and liabilities. Com-
pany X joins in the filing of a U.S. consolidated in-
come tax return with USP and is treated as one tax-
payer with Company P under paragraph (j)(2)(i) of
this section. Accordingly, under paragraph (b)(3)(v)
of this section, Company P’s acquisition of the stock
of Company X will be treated as an indirect acqui-
sition of the resources and capabilities of Company
X. The in-process technology and workforce of Com-
pany X acquired by Company P are reasonably antic-
ipated to contribute to the development of product Z
and therefore the RT Rights in the in-process technol-
ogy and workforce of Company X are external contri-
butions for which compensation is due to Company P
from Company S under a PCT. Furthermore, because
these external contributions were acquired by Com-
pany P in an uncontrolled transaction that took place
after the formation of the CSA, they are also PFAs.
Accordingly, the consideration due from S under the
PCT must be paid in the same form of payment as
Company P’s acquisition of Company X, which was
done in a lump sum payment. Therefore, considera-
tion for the PCT must be paid in a lump sum.
(4)Territorial division of interests—(i)
In general. Pursuant to paragraph (b)(1)(i)
of this section, at the outset of the CSA the
controlled participants must divide among
themselves all interests in cost shared in-
tangibles on a territorial basis as follows.
The entire world must be divided into two
or more non-overlapping geographic terri-
tories. Each controlled participant must re-
ceive at least one such territory, and in the
aggregate all the participants must receive
all such territories. Each controlled partic-
ipant must be entitled to the perpetual and
exclusive right to the profits from trans-
actions of any member of the controlled
group that includes the controlled partic-
ipant with uncontrolled taxpayers regard-
ing property or services for use, consump-
tion, or disposition in such controlled par-
ticipant’s territory or territories, to the ex-
tent that such profits are attributable to cost
shared intangibles. Absent the controlled
participant’s or other member of its con-
trolled group’s actual knowledge or reason
to know otherwise, for purposes of the pre-
ceding sentence such use, consumption, or
disposition of property or services will be
considered to occur at the location(s) to
which notices and other communications
to the uncontrolled taxpayer(s) are to be
provided in accordance with the contrac-
tual provisions of the relevant transactions.
(ii)Example. The following example
illustrates the principles of this paragraph
(b)(4):
Example. Companies P and S, both members of
the same controlled group, enter into a CSA to de-
velop product Z. Under the CSA, P receives the in-
terest in product Z in the United States and S receives
the interest in product Z in the rest of the world, as
described in paragraph (b)(4)(i) of this section. Both
P and S have plants for manufacturing product Z lo-
cated in their respective geographic territories. How-
ever, for commercial reasons product Z is neverthe-
less manufactured by P in the United States for sale to
customers in certain locations just outside the United
States in close proximity to P’s U.S. manufacturing
plant. Because S owns the territorial rights outside
the United States, intercompany compensation must
be provided for between P and S to ensure that S real-
izes all the cost shared intangible profits from sales of
product Z to customers in such proximate areas, even
though the manufacturing is done by P in the United
States. The pricing of such intercompany compen-
sation must also ensure that P realizes an appropri-
ate manufacturing return for its efforts. Benefits pro-
jected with respect to such sales will be included for
purposes of estimating S’s, but not P’s, RAB share.
(5)CSAs in substance or form—(i)
CSAs in substance. The Commissioner
may apply, consistently with the rules of
§1.482–1(d)(3)(ii)(B) (Identifying con-
tractual terms), the rules of this section
to any arrangement that in substance con-
stitutes a CSA described in paragraphs
(b)(1)(i) through (iii)of this section, not-
withstanding a failure to comply with any
requirement of this section.
(ii)CSAs in form. Provided the require-
ments of paragraphs (b)(1)(iv) through
(vii) are met with respect to an arrange-
ment among controlled taxpayers,
(A) The Commissioner must apply the
rules of this section to any such arrange-
ment that the controlled taxpayers reason-
ably concluded to be a CSA, as described
in paragraph (b)(1) of this section; and
(B) Otherwise, the Commissioner may
applytherulesofthissectiontoanyother
such arrangement.
(iii)Examples. The following examples
illustrate the principles of this paragraph
(b)(5). In the examples, assume that Com-
panies P and S are both members of the
same controlled group. The examples are
as follows:
Example 1. (i) P owns the patent on a formula for
a capsulated pain reliever, P-Cap. P reasonably an-
ticipates, pending further research and experimenta-
tion, that the P-Cap formula could form the platform
for a formula for P-Ves, aneffervescent version of
P-Cap. P also owns proprietary software that it rea-
sonably anticipates to be critical to the research ef-
forts. P and S execute a CSA by which they agree to
proportionally share the costs and risks of develop-
ing a formula for P-Ves. The agreement reflects the
various contractual requirements described in para-
graph (k)(1) of this section and P and S comply with
the documentation, accounting and reporting require-
ments of paragraphs (k)(2) through (4) of this section.
Both the patent for P-Cap and the software are rea-
sonably anticipated to contribute to the development
of P-Ves and therefore are external contributions for
2005–40 I.R.B.648October 3, 2005

which compensation is due from S as part of PCTs.
Though P and S enter into a PCT for the P-Cap patent,
they fail to enter into a PCT for the software.
(ii) In this case, P and S have substantially com-
plied with the contractual requirements of paragraph
(k)(1) of this section and the documentation, ac-
counting and reporting requirements of paragraphs
(k)(2) through (4) of this section and therefore have
met the formal requirements of paragraphs (b)(1)(iv)
through (vii) of this section. However, because they
did not enter into a PCT, as required under paragraph
(b)(1)(i) of this section, for the software that was
reasonably anticipated to be critical to the devel-
opment of P-Ves, they cannot reasonably conclude
that their arrangement was a CSA. Accordingly,
the Commissioner is not required under paragraph
(b)(5)(ii)(A) of this section to apply the rules of this
section to their arrangement. Nevertheless, pursuant
to paragraph (b)(5)(ii)(B), the Commissioner may
apply the rules of this section and treat P and S as
entering into a PCT for the software in accordance
with the requirements of paragraph (b)(1)(i) of this
section, and make any appropriate allocations under
paragraph (i) of this section. Alternatively, the Com-
missioner may decide that the arrangement is not a
CSA described in paragraph (b)(1) of this section and
therefore that this section’s provisions do not apply in
determining whether the arrangement reaches arm’s
length results. In this case, the arrangement would
be analyzed under the methods under the section 482
regulations, without regard to this section, to deter-
mine whether the arrangement reaches such results.
Example 2. ThefactsarethesameasExample
1except that P and S do enter into a PCT for the
software. Although the Commissioner determines
that the PCT Payments for the software were not
arm’s length, nevertheless, under the facts and cir-
cumstances at the time they entered into the CSA
and PCTs, P and S reasonably concluded their ar-
rangement to be a CSA. Because P and S have met
the requirements of paragraphs (b)(1)(iv) through
(vii) and reasonably concluded their arrangement is
a CSA, pursuant to paragraph (b)(5)(ii)(A) of this
section, the Commissioner must apply the rules of
this section to their arrangement. Accordingly, the
Commissioner treats the arrangement as a CSA and
makes adjustments to the PCT Payments as appro-
priate under this section to achieve an arm’s length
result for the PCT for the software.
(6)Treatment of CSAs.See
§301.7701–1(c) of this chapter for the
treatment of CSAs for purposes of the
Internal Revenue Code.
(c)Make-or-sell rights excluded—(1)
In general. Any right to exploit an ex-
isting intangible without further develop-
ment, such as the right to make or sell ex-
isting products, does not constitute an ex-
ternal contribution to a CSA, as described
in paragraph (b)(3) of this section. Thus,
the arm’s length compensation for such
rights does not satisfy the compensation
obligation under a PCT.
(2)Examples. The following examples
illustrate the principles of this paragraph
(c):
Example 1. P and S, who are members of the same
controlled group, execute a CSA that is described in
paragraph (b)(1) of this section. Under the CSA, P
and S will bear their proportional shares of IDCs for
developing the second generation of ABC, a com-
puter software program. Prior to that arrangement,
P had incurred substantial costs and risks to develop
ABC. Concurrently with entering into the arrange-
ment, P (as the licensor) executes a license with S (as
the licensee) by which S may make and sell copies
of the existing ABC. Such make-and-sell rights do
not constitute an external contribution to the CSA.
The rules of §§1.482–1 and 1.482–4 through 1.482–6,
without regard to the rules of this section, must be ap-
plied to determine the arm’s length consideration in
connection with the make-and-sell licensing arrange-
ment. In certain circumstances, this determination
of the arm’s length consideration may be done on an
aggregate basis with the evaluation of compensation
obligations pursuant to PCTs entered into by P and S
in connection with the CSA. See paragraph (g)(2)(v)
of this section.
Example 2. (i) P, a software company, has devel-
oped and currently exploits software program ABC.
P and S enter into a CSA to develop future genera-
tions of ABC. The ABC source code is the platform
on which future generations of ABC will be built and
is therefore an external contribution of P for which
compensation is due from S pursuant to a PCT. Con-
currently with entering into the CSA, P licenses to
S the make-and-sell rights for the current version of
ABC. P has entered into similar licenses with un-
controlled parties calling for sales-based royalty pay-
ments at a rate of 20%. The current version of ABC
has an expected product life of three years. P and S
enter into a contingent payment agreement to cover
both the PCT Payments due from S for P’s external
contribution and for the make-and-sell license. Based
on the uncontrolled make-and-sell licenses, P and S
agree on a sales-based royalty rate of 20% in Year 1
that declines on a straight line basis to 0% over the 3
year product life of ABC.
(ii) The make-and-sell rights for the current ver-
sion of ABC are not external contributions, though
paragraph (g)(2)(v) of this section provides for the
possibility that the most reliable determination of an
arm’s length charge for the PCT and the make-and-
sell license may be one that values the two transac-
tions in the aggregate. A contingent payment sched-
ule based on the uncontrolled make-and-sell licenses
may provide an arm’s length charge for the separate
make-and-sell license between P and S, provided the
royalty rates in the uncontrolled licenses similarly de-
cline, but as a measure of the aggregate PCT and
license payments it does not account for the arm’s
length value of P’s external contributions which in-
clude the RT Rights in the source code and future de-
velopment rights in ABC.
(d)Intangible development costs
(IDCs)—(1)Costs included in IDCs.
For purposes of this section, IDCs mean
allcosts,incashorinkind(including
stock-based compensation, as described
in paragraph (d)(3) of this section), but
excluding costs for land or depreciable
property, in the ordinary course of busi-
ness after the formation of a CSA that,
based on analysis of the facts and circum-
stances, are directly identified with, or are
reasonably allocable to, the activity un-
der the CSA of developing or attempting
to develop intangibles (IDA). IDCs shall
also include the arm’s length rental charge
for the use of any land or depreciable
tangible property (as determined under
§1.482–2(c) (Use of tangible property))
directly identified with, or reasonably
allocable to, the IDA. Reference to gen-
erally accepted accounting principles or
federal income tax accounting rules may
provide a useful starting point but will not
be conclusive regarding inclusion of costs
in IDCs. IDCs do not include interest ex-
pense, foreign income taxes (as defined in
§1.901–2(a)), or domestic income taxes.
(2)Allocation of costs. If a particu-
lar cost is reasonably allocable both to the
IDA and to other business activities, the
cost must be allocated on a reasonable ba-
sis between the IDA and such other busi-
ness activities in proportion to the rela-
tive economic value that the IDA and such
other business activities are anticipated to
derive over time as a result of such cost.
(3)Stock-based compensation—(i)In
general. As used in this section, the term
stock-based compensationmeans any
compensation provided by a controlled
participant to an employee or independent
contractor in the form of equity instru-
ments, options to acquire stock (stock
options), or rights with respect to (or
determined by reference to) equity instru-
ments or stock options, including but not
limitedtopropertytowhichsection83
applies and stock options to which section
421 applies, regardless of whether ulti-
mately settled in the form of cash, stock,
or other property.
(ii)Identification of stock-based com-
pensation with the IDA. The determination
of whether stock-based compensation is
directly identified with, or reasonably
allocable to, the IDA is made as of the
date that the stock-based compensation
is granted. Accordingly, all stock-based
compensation that is granted during the
term of the CSA and, at date of grant,
is directly identified with, or reasonably
allocable to, the IDA is included as an
IDC under paragraph (d)(1) of this sec-
tion. In the case of a repricing or other
modification of a stock option, the deter-
mination of whether the repricing or other
modification constitutes the grant of a new
October 3, 20056492005–40 I.R.B.

stock option for purposes of this paragraph
(d)(3)(ii) will be made in accordance with
the rules of section 424(h) and related
regulations.
(iii)Measurement and timing of stock-
based compensation IDC—(A)In gen-
eral. Except as otherwise provided in this
paragraph (d)(3)(iii), the cost attributable
to stock-based compensation is equal to
the amount allowable to the controlled par-
ticipant as a deduction for federal income
tax purposes with respect to that stock-
based compensation (for example, under
section 83(h)) and is taken into account as
an IDC under this section for the taxable
year for which the deduction is allowable.
(1)Transfers to which section 421 ap-
plies. Solely for purposes of this paragraph
(d)(3)(iii)(A), section 421 does not apply
to the transfer of stock pursuant to the ex-
ercise of an option that meets the require-
ments of section 422(a) or 423(a).
(2)Deductions of foreign controlled
participants. Solely for purposes of this
paragraph (d)(3)(iii)(A), an amount is
treated as an allowable deduction of a
controlled participant to the extent that a
deduction would be allowable to a United
States taxpayer.
(3)Modification of stock option.
Solely for purposes of this paragraph
(d)(3)(iii)(A), if the repricing or other
modification of a stock option is deter-
mined, under paragraph (d)(3)(ii) of this
section, to constitute the grant of a new
stock option not identified with, or reason-
ably allocable to, the IDA, the stock option
that is repriced or otherwise modified will
be treated as being exercised immediately
before the modification, provided that the
stockoptionisthenexercisableandthe
fair market value of the underlying stock
then exceeds the price at which the stock
option is exercisable. Accordingly, the
amount of the deduction that would be al-
lowable (or treated as allowable under this
paragraph (d)(3)(iii)(A)) to the controlled
participant upon exercise of the stock op-
tion immediately before the modification
must be taken into account as an IDC as
of the date of the modification.
(4)Expiration or termination of CSA.
Solely for purposes of this paragraph
(d)(3)(iii)(A), if an item of stock-based
compensation identified with, or reason-
ably allocable to, the IDA is not exercised
during the term of a CSA, that item of
stock-based compensation will be treated
as being exercised immediately before the
expiration or termination of the CSA, pro-
vided that the stock-based compensation
is then exercisable and the fair market
value of the underlying stock then exceeds
the price at which the stock-based com-
pensation is exercisable. Accordingly, the
amount of the deduction that would be
allowable (or treated as allowable under
this paragraph (d)(3)(iii)(A)) to the con-
trolled participant upon exercise of the
stock-based compensation must be taken
into account as an IDC as of the date of
the expiration or termination of the CSA.
(B)Election with respect to options on
publicly traded stock—(1)In general.
With respect to stock-based compensation
in the form of options on publicly traded
stock, the controlled participants in a CSA
may elect to take into account all IDCs
attributable to those stock options in the
same amount, and as of the same time,
as the fair value of the stock options re-
flected as a charge against income in au-
dited financial statements or disclosed in
footnotes to such financial statements, pro-
vided that such statements are prepared in
accordance with United States generally
accepted accounting principles by or on
behalf of the company issuing the publicly
traded stock.
(2)Publicly traded stock.Asusedin
this paragraph (d)(3)(iii)(B), the termpub-
licly traded stockmeans stock that is regu-
larly traded on an established United States
securities market and is issued by a com-
pany whose financial statements are pre-
pared in accordance with United States
generally accepted accounting principles
for the taxable year.
(3)Generally accepted accounting
principles. For purposes of this paragraph
(d)(3)(iii)(B), a financial statement pre-
pared in accordance with a comprehensive
body of generally accepted accounting
principles other than United States gen-
erally accepted accounting principles is
considered to be prepared in accordance
with United States generally accepted ac-
counting principles provided that either —
(i) The fair value of the stock options
under consideration is reflected in the rec-
onciliation between such other accounting
principles and United States generally ac-
cepted accounting principles required to be
incorporated into the financial statement
by the securities laws governing compa-
nies whose stock is regularly traded on
United States securities markets; or
(ii) In the absence of a reconciliation
between such other accounting principles
and United States generally accepted ac-
counting principles that reflects the fair
value of the stock options under consider-
ation, such other accounting principles re-
quire that the fair value of the stock op-
tions under consideration be reflected as
a charge against income in audited finan-
cial statements or disclosed in footnotes to
such statements.
(4)Time and manner of making the
election. The election described in this
paragraph (d)(3)(iii)(B) is made by an
explicit reference to the election in the
written CSA required by paragraph (k)(1)
ofthissectionorinawrittenamendment
to the CSA entered into with the consent of
the Commissioner pursuant to paragraph
(d)(3)(iii)(C) of this section. In the case of
a CSA in existence on August 26, 2003,
the election by written amendment to the
CSA may be made without the consent of
the Commissioner if such amendment is
entered into not later than the latest due
date (with regard to extensions) of a fed-
eral income tax return of any controlled
participant for the first taxable year begin-
ning after August 26, 2003.
(C)Consistency. Generally, all con-
trolled participants in a CSA taking op-
tions on publicly traded stock into ac-
count under paragraph (d)(3)(iii)(A) or
(d)(3)(iii)(B) of this section must use that
same method of measurement and timing
for all options on publicly traded stock
with respect to that CSA. Controlled par-
ticipants may change their method only
with the consent of the Commissioner and
only with respect to stock options granted
during taxable years subsequent to the
taxable year in which the Commissioner’s
consent is obtained. All controlled par-
ticipants in the CSA must join in requests
for the Commissioner’s consent under
this paragraph. Thus, for example, if the
controlled participants make the election
described in paragraph (d)(3)(iii)(B) of
this section upon the formation of the
CSA, the election may be revoked only
with the consent of the Commissioner, and
the consent will apply only to stock op-
tions granted in taxable years subsequent
to the taxable year in which consent is
obtained. Similarly, if controlled partici-
pants already have granted stock options
2005–40 I.R.B.650October 3, 2005

that have been or will be taken into ac-
count under the general rule of paragraph
(d)(3)(iii)(A) of this section, then except in
cases specified in the last sentence of para-
graph (d)(3)(iii)(B)(4) of this section, the
controlled participants may make the elec-
tion described in paragraph (d)(3)(iii)(B)
of this section only with the consent of the
Commissioner, and the consent will apply
only to stock options granted in taxable
years subsequent to the taxable year in
which consent is obtained.
(4)IDC share. A controlled partici-
pant’s IDC share for a taxable year is equal
to the controlled participant’s cost contri-
bution for the taxable year, divided by the
sum of all IDCs for the taxable year. A
controlled participant’s cost contribution
for a taxable year means all of the IDCs ini-
tially borne by the controlled participant,
plus all of the cost sharing payments that
the participant makes to other controlled
participants, minus all of the cost shar-
ing payments that the participant receives
from other controlled participants.
(5)Examples. The following examples
illustrate this paragraph (d):
Example 1. Foreign parent (FP) and its U.S. sub-
sidiary(USS)enterintoaCSAtodevelopabetter
mousetrap. USS and FP share the costs of FP’s R&D
facility that will be exclusively dedicated to this re-
search, the salaries of the researchers, and reason-
able overhead costs attributable to the project. They
also share the cost of a conference facility that is at
the disposal of the senior executive management of
each company. Based on the facts and circumstances,
the cost of the conference facility cannot be directly
identified with, and is not reasonably allocable to, the
IDA. In this case, the cost of the conference facility
must be excluded from the amount of IDCs.
Example 2. U.S. parent (USP) and its foreign sub-
sidiary (FS) enter into a CSA to develop intangibles
for producing a new device. USP and FS share the
costs of an R&D facility, the salaries of the facility’s
researchers, and reasonable overhead costs attribut-
able to the project. Although USP also incurs costs
related to field testing of the device, USP does not in-
clude those costs in the IDCs that USP and FS will
share under the CSA. The Commissioner may deter-
mine, based on the facts and circumstances, that the
costs of field testing are IDCs that the participants
must share.
Example 3. U.S. parent (USP) and its foreign
subsidiary (FS) enter into a CSA to develop a new
process patent. USP employs researchers who per-
form R&D functions in connection both with the de-
velopment of the new process patent and with the de-
velopment of a new design patent the development
of which is outside the scope of the CSA. During
years covered by the CSA, USP compensates such
employees with cash salaries, stock-based compen-
sation, or a combination of both. USP and FS antici-
pate that the economic value attributable to such em-
ployees will be derived from the process patent and
the design patent at a relative proportion of 75% and
25%, respectively. Applying the principles of para-
graph (d)(2) of this section, 75% of the compensation
of such employees must be allocated to the develop-
ment of the new process patent and, thus, treated as
IDCs. With respect to the cash salary compensation,
the IDC is 75% of the face value of the cash. With
respect to the stock-based compensation, the IDC is
75% of the value of the stock-based compensation as
determined under paragraph (d)(3)(iii) of this section.
Example 4. Foreign parent (FP) and its U.S. sub-
sidiary(USS)enterintoaCSAtodevelopanewcom-
puter source code. FP’s executive officers who over-
see a research facility and employees dedicated solely
to the IDA have additional responsibilities, including
oversight of other research facilities and employees
not in any way relevant to the development of the
new computer source code. The full amount of the
costs of the research facility and employees dedicated
solely to the IDA can be directly identified with the
IDA and, therefore, are IDCs. In addition, the par-
ticipants determine that, of the economic value at-
tributable to the executive officers, the new computer
source code’s share is 50%. Applying the principles
of paragraph (d)(2) of this section, 50% of the com-
pensation of such executives must be allocated to the
development of the new computer source code and,
thus, treated as IDCs.
(e)Reasonably anticipated benefits
share (RAB share)—(1)In general.A
controlled participant’s share of reason-
ably anticipated benefits (RAB share) is
equal to its reasonably anticipated bene-
fits divided by the sum of the reasonably
anticipated benefits of all the controlled
participants. See paragraph (j)(1)(v) of
this section (defining reasonably antic-
ipated benefits). RAB shares must be
updated to account for changes in eco-
nomic conditions, the business operations
and practices of the participants, and the
ongoing development of intangibles under
the CSA. For purposes of determining
RAB shares at any given time, reasonably
anticipated benefits must be estimated
over the entire period, past and future, of
exploitation of the cost shared intangibles,
and must reflect appropriate updates to
take into account the most current reliable
data regarding past and projected future
results as is available at such time. A
controlled participant’s RAB share must
be determined by using the most reliable
estimate. In determining which of two or
more available estimates is most reliable,
the quality of the data and assumptions
used in the analysis must be taken into ac-
count, consistent with §1.482–1(c)(2)(ii)
(Data and assumptions). Thus, the relia-
bility of an estimate will depend largely on
the completeness and accuracy of the data,
the soundness of the assumptions, and
the relative effects of particular deficien-
cies in data or assumptions on different
estimates. If two estimates are equally
reliable, no adjustment should be made
based on differences in the results. The
following factors will be particularly rel-
evant in determining the reliability of an
estimate of RAB shares —
(A) The basis used for measuring ben-
efits, as described in paragraph (e)(2)(i) of
this section; and
(B) The projections used to esti-
mate benefits, as described in paragraph
(e)(2)(iii) of this section.
(2)Measure of benefits—(i)In gen-
eral. In order to estimate a controlled par-
ticipant’s RAB share, the amount of each
controlled participant’s reasonably antici-
pated benefits must be measured on a ba-
sis that is consistent for all such partic-
ipants. See paragraph (e)(2)(ii)(E)Ex-
ample 8of this section. If a controlled
participant transfers a cost shared intangi-
ble to another controlled taxpayer, other
than by way of a transfer described in
paragraph (f) of this section, that partici-
pant’s benefits from the transferred intan-
gible must be measured by reference to
the transferee’s benefits, disregarding any
consideration paid by the transferee to the
controlled participant (such as a royalty
pursuant to a license agreement). Reason-
ably anticipated benefits are measured ei-
ther on a direct basis, by reference to esti-
mated benefits to be generated by the use
of cost shared intangibles, or on an in-
direct basis, by reference to certain mea-
surements that reasonably can be assumed
to be related to benefits to be generated.
Such indirect bases of measurement of an-
ticipated benefits are described in para-
graph (e)(2)(ii) of this section. A con-
trolled participant’s reasonably anticipated
benefits must be measured on the basis,
whether direct or indirect, that most reli-
ably determines RAB shares. In determin-
ing which of two bases of measurement
is most reliable, the factors set forth in
§1.482–1(c)(2)(ii) (Data and assumptions)
must be taken into account. It normally
will be expected that the basis that pro-
vided the most reliable estimate for a par-
ticular year will continue to provide the
most reliable estimate in subsequent years,
absent a material change in the factors that
affect the reliability of the estimate. Re-
gardless of whether a direct or indirect ba-
sis of measurement is used, adjustments
October 3, 20056512005–40 I.R.B.

may be required to account for material
differences in the activities that controlled
participants undertake to exploit their in-
terests in cost shared intangibles. SeeEx-
ample 6of paragraph (e)(2)(ii)(E) of this
section.
(ii)Indirect bases for measuring antic-
ipated benefits. Indirect bases for measur-
ing anticipated benefits from participation
in a CSA include the following:
(A)Units used, produced, or sold.
Units of items used, produced, or sold by
each controlled participant in the business
activities in which cost shared intangibles
are exploited may be used as an indirect
basis for measuring its anticipated bene-
fits. This basis of measurement will more
reliably determine RAB shares to the ex-
tent that each controlled participant is
expected to have a similar increase in net
profit or decrease in net loss attributable
to the cost shared intangibles per unit of
the item or items used, produced, or sold.
This circumstance is most likely to arise
when the cost shared intangibles are ex-
ploited by the controlled participants in the
use, production, or sale of substantially
uniform items under similar economic
conditions.
(B)Sales. Sales by each controlled par-
ticipant in the business activities in which
cost shared intangibles are exploited may
be used as an indirect basis for measur-
ing its anticipated benefits. This basis of
measurement will more reliably determine
RAB shares to the extent that each con-
trolled participant is expected to have a
similar increase in net profit or decrease in
net loss attributable to cost shared intangi-
bles per dollar of sales. This circumstance
is most likely to arise if the costs of exploit-
ing cost shared intangibles are not substan-
tial relative to the revenues generated, or if
the principal effect of using cost shared in-
tangibles is to increase the controlled par-
ticipants’ revenues (for example, through
a price premium on the products they sell)
without affecting their costs substantially.
Sales by each controlledparticipant are un-
likely to provide a reliable basis for mea-
suring RAB shares unless each controlled
participant operates at the same market
level (for example, manufacturing, distri-
bution, etc.).
(C)Operating profit. Operating profit
of each controlled participant from the ac-
tivities in which cost shared intangibles are
exploited, as determined before any ex-
pense (including amortization) on account
of IDCs, may be used as an indirect basis
for measuring anticipated benefits. This
basis of measurement will more reliably
determine RAB shares to the extent that
such profit is largely attributable to the use
of cost shared intangibles, or if the share
of profits attributable to the use of cost
shared intangibles is expected to be sim-
ilar for each controlled participant. This
circumstance is most likely to arise when
cost shared intangibles are closely asso-
ciated with the activity that generates the
profit and the activity could not be carried
on or would generate little profit without
use of those intangibles.
(D)Other bases for measuring antic-
ipated benefits. Other bases for measur-
ing anticipated benefits may, in some cir-
cumstances, be appropriate, but only to the
extent that there is expected to be a rea-
sonably identifiable relationship between
the basis of measurement used and addi-
tional income generated or costs saved by
the use of cost shared intangibles. For ex-
ample, a division of costs based on em-
ployee compensation would be considered
unreliable unless there were a relationship
between the amount of compensation and
the expected income of the controlled par-
ticipants from using the cost shared intan-
gibles.
(E)Examples. The following examples
illustrate this paragraph (e)(2)(ii):
Example 1. Foreign Parent (FP) and U.S. Sub-
sidiary (USS) both produce a feedstock for the manu-
facture of various high-performance plastic products.
Producing the feedstock requires large amounts of
electricity, which accounts for a significant portion
of its production cost. FP and USS enter into a CSA
to develop a new process that will reduce the amount
of electricity required to produce a unit of the feed-
stock. FP and USS currently both incur an electricity
cost of $2 per unit of feedstock produced and rates
for each are expected to remain similar in the future.
The new process, if it is successful, will reduce the
amount of electricity required by each company to
produce a unit of the feedstock by 50%. Therefore,
the cost savings each company is expected to achieve
after implementing the new process are $1 per unit of
feedstock produced. UndertheCSA,FPandUSSdi-
vide the costs of developing the new process based on
the units of the feedstock each is anticipated to pro-
duce in the future. In this case, units produced is the
most reliable basis for measuring RAB shares and di-
viding the IDCs because each controlled participant is
expected to have a similar $1 (50% of current charge
of $2) decrease in costs per unit of the feedstock pro-
duced.
Example 2. The facts are the same as inExam-
ple 1, except that currently USS pays $3 per unit of
feedstock produced for electricity while FP pays $6
per unit of feedstock produced. In this case, units
produced is not the most reliable basis for measuring
RAB shares and dividing the IDCs because the par-
ticipants do not expect to have a similar decrease in
costs per unit of the feedstock produced. The Com-
missioner determines that the most reliable measure
of RAB shares may be based on units of the feed-
stock produced if FP’s units are weighted relative to
USS’s units by a factor of 2. This reflects the fact
that FP pays twice as much as USS for electricity
and, therefore, FP’s savings of $3 per unit of the feed-
stock (50% reduction of current charge of $6) would
be twice USS’s savings of $1.50 per unit of feedstock
(50% reduction of current charge of $3) from any new
process eventually developed.
Example 3. ThefactsarethesameasinExam-
ple 2, except that to supply the particular needs of
the U.S. market USS manufactures the feedstock with
somewhat different properties than FP’s feedstock.
This requires USS to employ a somewhat different
production process than does FP. Because of this dif-
ference, it will be more costly for USS to adopt any
new process that may be developed under the cost
sharing agreement. In this case, units produced is
not the most reliable basis for measuring RAB shares.
In order to reliably determine RAB shares, the Com-
missioner offsets the reasonably anticipated costs of
adopting the new process against the reasonably an-
ticipated total savings in electricity costs.
Example 4. U.S. Parent (USP) and Foreign Sub-
sidiary (FS) enter into a CSA to develop new anes-
thetic drugs. USP obtains the right to use any result-
ing patent in the U.S. market, and FS obtains the right
to use the patent in the rest of the world. USP and
FS divide costs on the basis of anticipated operating
profit from each patent under development. USP an-
ticipates that it will receive a much higher profit than
FS per unit sold because drug prices are uncontrolled
in the United States, whereas drug prices are regu-
lated in many non-U.S. jurisdictions. In both con-
trolled participants’ territories, the operating profits
are almost entirely attributable to the use of the cost
shared intangible. In this case, the controlled partic-
ipants’ basis for measuring RAB shares is the most
reliable.
Example 5. (i) Foreign Parent (FP) and U.S. Sub-
sidiary (USS) both manufacture and sell fertilizers.
They enter into a CSA to develop a new pellet form
of a common agricultural fertilizer that is currently
available only in powder form. Under the CSA, USS
obtains the rights to produce and sell the new form
of fertilizer for the U.S. market while FP obtains the
rights to produce and sell the fertilizer for the rest of
the world. The costs of developing the new form of
fertilizer are divided on the basis of the anticipated
sales of fertilizer in the controlled participants’ re-
spective markets.
(ii) If the research and development is successful,
the pellet form will deliver the fertilizer more effi-
ciently to crops and less fertilizer will be required to
achieve the same effect on crop growth. The pellet
form of fertilizer can be expected to sell at a price
premium over the powder form of fertilizer based on
the savings in the amount of fertilizer that needs to be
used. This price premium will be a similar premium
per dollar of sales in each territory. If the research
and development is successful, the costs of producing
pellet fertilizer are expected to be approximately the
same as the costs of producing powder fertilizer and
2005–40 I.R.B.652October 3, 2005

the same for both FP and USS. Both FP and USS op-
erate at approximately the same market levels, selling
their fertilizers largely to independent distributors.
(iii) In this case, the controlled participants’ basis
for measuring RAB shares is the most reliable.
Example 6. ThefactsarethesameasinExam-
ple 5, except that FP distributes its fertilizers directly
while USS sells to independent distributors. In this
case, sales of USS and FP are not the most reliable
basis for measuring RAB shares unless adjustments
are made to account for the difference in market lev-
els at which the sales occur.
Example 7. Foreign Parent (FP) and U.S. Sub-
sidiary (USS) enter into a CSA to develop materials
that will be used to train all new entry-level employ-
ees. FP and USS determine that the new materials
will save approximately ten hours of training time per
employee. Because their entry-level employees are
paid on differing wage scales, FP and USS decide that
they should not measure benefits based on the num-
ber of entry-level employees hired by each. Rather,
they measure benefits based on compensation paid to
the entry-level employees hired by each. In this case,
the basis used for measuring RAB shares is the most
reliable because there is a direct relationship between
compensation paid to new entry-level employees and
costs saved by FP and USS from the use of the new
training materials.
Example 8. U.S.Parent(USP),ForeignSub-
sidiary1(FS1)andForeignSubsidiary2(FS2)enter
into a CSA to develop computer software that each
will market and install oncustomers’ computer sys-
tems. The controlled participants measure benefits
on the basis of projected sales by USP, FS1, and
FS2 of the software in their respective geographic
areas. However, FS1 plans not only to sell but also
to license the software to unrelated customers, and
FS1’s licensing income (which is a percentage of
the licensees’ sales) is not counted in the projected
benefits. In this case, the basis used for measuring
the benefits of each controlled participant is not the
most reliable because all of the benefits received by
controlled participants are not taken into account.
In order to reliably determine RAB shares, FS1’s
projected benefits from licensing must be included
in the measurement on a basis that is the same as
that used to measure its own and the other controlled
participants’ projected benefits from sales (for exam-
ple, all controlled participants might measure their
benefits on the basis of operating profit).
(iii)Projections used to estimate bene-
fits—(A)In general. The reliability of an
estimate of RAB shares also depends upon
the reliability of projections used in mak-
ing the estimate. Projections required for
this purpose generally include a determi-
nation of the time period between the in-
ception of the research and development
activities under the CSA and the receipt
of benefits, a projection of the time over
which benefits will be received, and a pro-
jection of the benefits anticipated for each
year in which it is anticipated that the cost
shared intangible will generate benefits. A
projection of the relevant basis for measur-
ing anticipated benefits may require a pro-
jection of the factors that underlie it. For
example, a projection of operating profits
may require a projection of sales, cost of
sales, operating expenses, and other fac-
tors that affect operating profits. If it is an-
ticipated that there will be significant vari-
ation among controlled participants in the
timing of their receipt of benefits, and con-
sequently benefit shares are expected to
vary significantly over the years in which
benefits will be received, it normally will
be necessary to use the present discounted
value of the projected benefits to reliably
determine RAB shares. See paragraph
(g)(2)(vi) of this section for guidance on
discount rates used for this purpose. If it is
not anticipated that benefit shares will sig-
nificantly change over time, current annual
benefit shares may provide a reliable pro-
jection of RAB shares. This circumstance
is most likely to occur when the CSA is
a long-term arrangement, the arrangement
covers a wide variety of intangibles, the
composition of the cost shared intangibles
is unlikely to change, the cost shared in-
tangibles are unlikely to generate unusual
profits, and each controlled participant’s
share of the market is stable.
(B)Examples. The following examples
illustrate the principles of this paragraph
(e)(2)(iii):
Example 1. (i) Foreign Parent (FP) and U.S. Sub-
sidiary(USS)enterintoaCSAtodevelopanew
car model. The controlled participants plan to spend
four years developing the new model and four years
producing and selling the new model. USS and FP
project total sales of $4 billion and $2 billion, respec-
tively, over the planned four years of exploitation of
the new model. Cost shares are divided for each year
based on projected total sales. Therefore, USS bears
66 2/3% of each year’s IDCs and FP bears 33 1/3%
of such costs.
(ii) USS typically begins producing and selling
new car models a year after FP begins producing and
selling new car models. In order to reflect USS’s
one-year lag in introducing new car models, a more
reliable projection of each participant’s RAB share
would be based on a projection of all four years of
sales for each participant, discounted to present value.
Example 2. U.S. Parent (USP) and Foreign Sub-
sidiary (FS) enter into a CSA to develop new and im-
proved household cleaning products. Both controlled
participants have sold household cleaning products
for many years and have stable market shares. The
products under development are unlikely to produce
unusual profits for either controlled participant. The
controlled participants divide costs on the basis of
each controlled participant’s current sales of house-
hold cleaning products. In this case, the controlled
participants’ RAB sharesare reliably projected by
current sales of cleaning products.
Example 3. The facts are the same as inExample
2, except that FS’s market share is rapidly expanding
because of the business failure of a competitor in its
geographic area. The controlled participants’ RAB
shares are not reliably projected by current sales of
cleaning products. FS’s benefit projections should
take into account its growth in sales.
Example 4. Foreign Parent (FP) and U.S. Sub-
sidiary (USS) enter into a CSA to develop synthetic
fertilizers and insecticides. FP and USS share costs
on the basis of each controlled participant’s current
sales of fertilizers and insecticides. The market
shares of the controlled participants have been stable
for fertilizers, but FP’s market share for insecticides
has been expanding. The controlled participants’
projections of RAB shares are reliable with regard
to fertilizers, but not reliable with regard to insec-
ticides; a more reliable projection of RAB shares
would take into account the expanding market share
for insecticides.
(f)Changes in participation under a
CSA— In the case of any change in par-
ticipation under a CSA as the result of a
controlled transfer of all or part of a con-
trolled participant’sterritorial rights under
the CSA, as described in paragraph (b)(4)
of this section, along with the assump-
tion by the transferee of the associated
obligations under the CSA, the transferee
will be treated as succeeding to the trans-
feror’s prior history under the CSA, in-
cluding the transferor’s cost contributions,
benefits derived, and PCT Payments attrib-
utable to such rights or obligations. The
transferor must receive an arm’s length
amount of consideration from the trans-
feree under the rules of §§1.482–1 and
1.482–4 through 1.482–6, as described in
paragraph (a)(3)(ii) of this section. For
purposes of this section, such a change in
participation under a CSA includes, for ex-
ample, any transaction in which —
(1) A controlled participant transfers all
or part of its territorial rights to another
controlled participant that assumes the as-
sociated obligations under a CSA;
(2) A new controlled participant enters
an ongoing CSA and acquires any territo-
rial rights and assumes associated obliga-
tions under the CSA; or
(3) A controlled participant withdraws
from an ongoing CSA, or otherwise aban-
dons or relinquishes territorial rights and
associated obligations under the CSA.
(g)Supplemental guidance on methods
applicable to PCTs—(1)In general.This
subsection provides supplemental guid-
ance on applying the methods listed below
for purposes of evaluating the arm’s length
amount charged in a PCT. Each method
must be applied in accordance with the
provisions of §1.482–1, including the best
October 3, 20056532005–40 I.R.B.

method rule of §1.482–1(c), the compa-
rability analysis of §1.482–1(d), and the
arm’s length range of §1.482–1(e), except
as those provisions are modified in this
subsection. The methods are —
(i) The comparable uncontrolled trans-
action method described in §1.482–4(c),
or the arm’s length charge described in
§1.482–2(b)(3)(first sentence) based on a
comparable uncontrolled transaction, fur-
ther described in paragraph (g)(3) of this
section;
(ii) The income method, described in
paragraph (g)(4) of this section;
(iii) The acquisition price method, de-
scribed in paragraph (g)(5) of this section;
(iv) The market capitalization method,
described in paragraph (g)(6) of this sec-
tion;
(v) The residual profit split method, de-
scribed in paragraph (g)(7) of this section;
and
(vi) Unspecified methods, described in
paragraph (g)(8) of this section.
(2)General principles—(i)In general.
The principles set forth in this paragraph
(g)(2) apply, as appropriate, to the use of
any of the methods set forth in this section
to determine the arm’s length charge for a
PCT.
(ii)Valuations consistent with upfront
contractual terms and risk allocations.
The application of any method as of any
time must be consistent with the applica-
ble contractual terms and allocation of risk
under the CSA and this section among the
controlled participants as of the date of
the PCT, unless there has been a change
in such terms or allocation made in return
for arm’s length consideration.
(iii)Projections. The reliability of an
estimate of the value of an external contri-
bution in connection with a PCT will often
depend upon the reliability of projections
used in making the estimate. Projections
necessary for this purpose may include a
projection of sales, IDCs, routine operat-
ing expenses, and costs of sales. For these
purposes, projections that have been pre-
pared for non-tax purposes are generally
more reliable than projections that have
been prepared solely for purposes of meet-
ing the requirements in this paragraph (g).
(iv)Realistic alternatives—(A)In gen-
eral. Regardless of the method or methods
used, evaluation of the arm’s length charge
for the PCT in question should take into
account the general principle that uncon-
trolled taxpayers dealing at arm’s length
would have evaluated the terms of a trans-
action, and only entered into a particu-
lar transaction, if no alternative is prefer-
able. This condition is not met, for exam-
ple, where for any controlled participant
the total anticipated present value from en-
tering into the CSA to that controlled par-
ticipant, as of the date of the PCT, is less
than the total anticipated present value that
could be achieved through an alternative
arrangement realistically available to that
controlled participant. When applying the
realistic alternatives principle, the reliabil-
ity of the respective net present value cal-
culations may need to be considered.
(B)Examples. The following examples
illustrate the principles of this paragraph
(g)(2)(iv):
Example 1. (i) P, a corporation, and S, a wholly-
owned subsidiary of P, enter into a CSA to develop a
gyroscopic personal transportation device (the prod-
uct). Under the arrangement, P will undertake all
of the R&D, and manufacture and market the prod-
uct in Country X. S will make CST payments to P
for its appropriate shareof P’s R&D costs, and man-
ufacture and market the product in the rest of the
world. P owns existing patents and trade secrets as-
sociated with gyroscopic applications. These patents
and trade secrets are reasonably anticipated to con-
tribute to the development of the product and there-
fore the RT Rights in the patents and trade secrets are
external contributions for which compensation is due
from S as part of a PCT.
(ii) S’s manufacturing and distribution activities
under the CSA will be routine in nature, and identical
to the activities it would undertake if it alternatively
licensed the product from P.
(iii) Reasonably reliable estimates indicate that
P could self-develop and license the product outside
of Country X for a royalty of 20% of sales. Based
on reliable financial projections that include all fu-
ture development costs and licensing revenue, the net
present value of this licensing alternative to P for the
non-Country X market (measured as of the date of
the PCT) would be $500 million of operating income.
Thus, based on this realistic alternative, the antici-
pated net present value under the CSA to P in the
non-Country X market (measured as of the date of the
PCT), including R&D reimbursement and PCT Pay-
ments from S, should not be less than $500 million.
Example 2. (i) The facts are the same asExample
1, except that there are no reliable estimates of the
value to P from the licensing alternative to the CSA.
However, reasonably reliable estimates indicate that
S can earn a 10% mark-up on total accounting costs
related to its routine manufacturing and distribution
activities.
(ii) P undertakes an economic analysis that de-
rives S’s cost contributions under the CSA, based on
reliable financial projections. Based on this and fur-
ther economic analysis, P determines S’s PCT Pay-
ment as a certain lump sum amount to be paid as of
the date of the PCT.
(iii) Based on reliable financial projections that
include S’s cost contributions and that incorporate S’s
PCT Payment, and using a discount rate of D%, ap-
propriate for the riskiness of the CSA (see paragraph
(g)(2)(vi) of this section), the anticipated net present
value to S under the CSA (measured at the time of the
PCT) is $800 million. Of this amount, $100 million
is the portion associated with the 10% markup on S’s
total accounting costs from its manufacturing and dis-
tribution activities, utilizing its existing investment in
plant and equipment.
(iv) In evaluating the PCT under the CSA, the
Commissioner concludes that the respective activi-
ties undertaken by P and S would be identical regard-
less of whether the arrangement was undertaken as
a CSA or as a licensing arrangement. That is, un-
der either alternative, P would undertake all research
activities and S would undertake routine manufactur-
ing and distribution activities associated with its ter-
ritory. Consequently, in every year the total antici-
pated combined nominal profits of P and S would be
identical regardless of whether the arrangement was
undertaken as a CSA or as a licensing arrangement.
In addition, the Commissioner considers the fact that
S’s economic role in the CSA (beyond its routine ac-
tivities) is merely that of an investor. A similarly sit-
uated investor would be willing to invest an amount
in a similar R&D project such that it earns an antici-
pated return on that investment of D% and therefore
has a net present value of $0 on the project (not tak-
ing into account any returns to routine activities). If S
were to realize a D% return on its lump sum PCT Pay-
ment, then the anticipated net present value to S of the
CSA would be $100 million, equal to the $100 mil-
lion anticipated net present value related to S’s man-
ufacturing and distribution activities, utilizing its ex-
isting investment in plant and equipment, plus the $0
anticipated net present value from the investment in
the form of the lump sum PCT Payment in the IDA
of the CSA at a D% discount rate.
(v) The lump sum PCT Payment computed by
P results in S having significantly higher antici-
pated discounted profitability, and therefore, in this
case, higher anticipated nominal profitability, than
it could achieve under the licensing alternative. By
implication, P must correspondingly earn lower
nominal profits under the CSA than it would under
the licensing alternative (that is, S’s enhanced prof-
itability under the CSA is matched dollar-for-dollar
by P’s reduced profitability under the CSA). Con-
sequently, the Commissioner concludes that P is
earning a lower anticipated return through the CSA
than it could achieve under its realistic alternative
to the CSA, and that consequently S’s lump sum
PCT Payment under-compensates P for its external
contribution.
Example 3. (i)ThefactsarethesameasExam-
ple 2except as follows. Based on reliable financial
projections that include S’s cost contributions and S’s
PCT Payment, discounted at a rate of D% to reflect
the riskiness of the CSA, the anticipated net present
value to S under the CSA (measured as of the date of
the PCT) is $50 million. Instead of entering the CSA,
S has the realistic alternative of investing in an R&D
project with similar risk, at an anticipated return of
D%, and manufacturing and distributing products un-
related to the gyroscopic personal transportation de-
vice to the same extent as its manufacturing and dis-
tribution under the CSA, with the same anticipated
10% mark-up on total costs.
2005–40 I.R.B.654October 3, 2005

(ii) Under its realistic alternative, at a discount
rate of D%, S anticipates a present value of $100 mil-
lion from the routine manufacturing and distribution
and $0 from the R&D investment, for a total of $100
million.
(iii) Because the lump sum PCT Payment made
by S results in S having a considerably lower antici-
pated net present value than S could achieve through
an alternative arrangement realistically available to it,
the Commissioner may conclude that the lump sum
PCT Payment overcompensates P for its external con-
tribution.
(v)Aggregation of transactions.In
some cases, controlled participants are
required to determine arm’s length pay-
ments for multiple PCTs covering various
external contributions or, in addition to
one or more PCTs, for transactions cov-
ering resources or capabilities that are not
governed by this section, such as the trans-
fer of make-or-sell rights as described in
paragraph (c) of this section. Following
the principles of aggregation described in
§1.482–1(f)(2)(i), a best method analysis
under §1.482–1(c) may determine that the
method that provides the most reliable
measure of an arm’s length charge for
the multiple PCTs and other transactions
not governed by this section, if any, is a
method that determines the arm’s length
charge for the multiple transactions on
an aggregate basis under this section. A
section 482 adjustment may be made by
comparing the aggregate arm’s length
charge so determined to the aggregate
payments actually made for the multiple
transactions. In such a case, it generally
will not be necessary to allocate separately
the aggregate arm’s length charge as be-
tween various PCTs or as between PCTs
and transactions governed by other regula-
tions under section 482. However, such an
allocation may be necessary for other pur-
poses, such as applying paragraph (i)(6)
(Periodic adjustments) of this section.
An aggregate determination of the arm’s
length charge for multiple transactions will
generally yield a payment for a controlled
participant that is equal to the aggregate
value of the external contributions and
other resources and capabilities covered
by the multiple transactions multiplied by
that controlled participant’s RAB share.
Because RAB shares only include benefits
from cost shared intangibles, the reliability
of an aggregate determination of payments
for multiple transactions may be reduced
to the extent that it includes transactions
not governed by this section covering
resources and capabilities for which the
controlled participants’ expected benefit
shares differ substantially from their RAB
shares.
(vi)Discount rate—(A)In general.
Some calculations set forth in this para-
graph (g) and elsewhere in this section re-
quire determining a rate of return which
is used to convert a future or past mone-
tary sum associated with a particular set
of activities or transactions into a present
value. For this purpose, a discount rate
should be used that most reliably reflects
the risk of the activities and the trans-
actions based on all the information po-
tentially available at the time for which
the present value calculation is to be per-
formed. Depending onthe particular facts
and circumstances, the risk involved and
thus, the discount rate, may differ among
a company’s various activities or transac-
tions. Normally, discount rates are most
reliably determined by reference to market
information. For example, the weighted
average cost of capital (WACC) of the rele-
vant activities and transactions derived us-
ing the capital asset pricing model might
provide the most reliable discount rate. In
such cases, this WACC might most reli-
ably be based on information from uncon-
trolled companies whose business activi-
ties as a whole constitute comparable un-
controlled transactions. Where a company
is publicly traded and its CSA involves
substantially the same risk as projects un-
dertaken by the company as a whole, then
the WACC of the relevant activities and
transactions might most reliably be based
on the company’s own WACC. Depending
on comparability and reliability consider-
ations, including the extent to which the
company’s hurdle rate reflects market in-
formation and is used in a similar manner
in the controlled and uncontrolled transac-
tions, in some circumstances discount rates
might be most reliably determined by ref-
erence to other data such as a company’s
internal hurdle rate for projects of compa-
rable risk.
(B)Examples. The following examples
illustrate the principles of this paragraph
(g)(2)(vi):
Example 1. USPharm, a publicly traded U.S.
pharmaceutical company, enters into a CSA with
FPharm, its wholly-owned foreign subsidiary. Under
the agreement, both controlled participants agree to
share the research costs of developing a specific drug
compound called T. USPharm is also engaged in an-
other development project for compounds U and V,
which involves different risks than the T development
project and which is not part of the CSA. However,
there are a large number of uncontrolled publicly
traded U.S. companies, for which information can
be reliably derived, that are highly comparable to
USPharm but that conduct research only on com-
pounds similar to T involving risks similar to those
of the T development project. At the commencement
of the CSA (Year 1), USPharm and FPharm enter
into a PCT with respect to external contributions
owned by USPharm consisting of the RT Rights in
its pre-existing drug research. As part of the method
that USPharm determines will most reliably calculate
PCT Payments, a discount rate is needed to convert
future monetary sums into a present value. After
analysis, USPharm concludes that the discount rate
is most reliably determined by calculating a WACC
basedontheinformationrelatingtothecomparable
uncontrolled companies, with suitable adjustments
for factors such as differences in capital structure
between USPharm and the comparables, and for the
stability and other statistical properties of the beta
measurement of the comparables.
Example 2.ThefactsarethesameasinExample
1except that the T development project is the only
business activity of USPharm and FPharm and no re-
liable data exists on uncontrolled companies under-
taking similar activities and risk as those associated
with the CSA. After analysis, USPharm concludes
that the discount rate is most reliably determined by
reference to its own WACC. USPharm funds its oper-
ations with debt and common stock. Debt comprises
40% of its financing and USPharm’s after-tax cost of
debt is 6%. Equity comprises the remaining 60% of
financing. USPharm is publicly traded and its equity
beta is 1.25. Using third party information, USPharm
concluded that the appropriate risk-free rate and eq-
uity risk premium are X% and Y%, respectively, im-
plying a return on USPharm’s equity of Z% [ X% +
( 1.25 × Y% )]. The weighted average cost of capital
is calculated by blending and weighting the after-tax
cost of debt and the cost of equity according to per-
centage of total financing. USPharm’s weighted av-
erage cost of capital is W% [( 6% × 0.4 ) + ( Z% ×
0.6 )].
Example 3.Use of a documented discount rate.

data exists on uncontrolled companies undertaking
similar activities and risks as those associated with

of 12% that it uses as the minimum anticipated
return for its business investments having a com-
parable risk profile. The Commissioner examines
USPharm’s documentation and concludes that the
hurdle rate provides a reliable discount rate in this
case.
(vii)Accounting principles—(A)In
general. Allocations or other valuations
done for accounting purposes may provide
a useful starting point but will not be con-
clusive for purposes of assessing or apply-
ing methods to evaluate the arm’s length
charge in a PCT, particularly where the ac-
counting treatment of an asset is inconsis-
tent with its economic value.
(B)Examples. The following examples
illustrate the principles of this paragraph
(g)(2)(vii):
October 3, 20056552005–40 I.R.B.

Example 1. (i) USP, a U.S. corporation and FSub,
a wholly-owned foreign subsidiary of USP, enter into
a CSA in Year 1 to develop software programs with
application in the medical field. Company X is an
uncontrolled software company located in the United
States that is engaged in developing software pro-
grams that could significantly enhance the programs
being developed by USP and FSub. Company X
is still in a startup phase, so it has no currently ex-
ploitable products or marketing intangibles and its
workforceconsistsofateamofsoftwaredevelop-
ers. Company X has negligible liabilities and tangible
property. In Year 2, USP purchases Company X as
part of an uncontrolled transaction in order to acquire
its in-process technology and workforce for purposes
of the development activities of the CSA. USP files
a consolidated return that includes Company X. For
accounting purposes, $50 million of the $100 million
acquisition price is allocated to the in-process tech-
nology and workforce, and the residual $50 million
is allocated to goodwill.
(ii) The in-process technology and workforce of
Company X acquired by USP are reasonably antici-
pated to contribute to developing cost shared intan-
gibles and therefore the RT Rights in the in-process
technology and workforce of Company X are exter-
nal contributions for which FSub must compensate
USP as part of a PCT. In determining whether to apply
the acquisition price or another method for purposes
of evaluating the arm’s length charge in the PCT,
relevant comparability and reliability considerations
must be weighed in light of the general principles of
paragraph (g)(2) of this section. The allocation for
accounting purposes raises an issue as to the reliabil-
ity of using the acquisition price method in this case
because it indicates that a significant portion of the
value of Company X’s assets is allocable to goodwill,
which is often difficult to value reliably and which,
depending on the facts and circumstances, might not
be attributable to external contributions that are to be
compensated by PCTs. See paragraph (g)(5)(iv)(A)
of this section.
(iii) Paragraph (g)(2)(vii) of this section provides
that accounting treatment may be a starting point, but
is not determinative for purposes of assessing or ap-
plying methods to evaluate the arm’s length charge
in a PCT. The facts here reveal that Company X has
nothing of economic value aside from its in-process
technology and assembled workforce. The $50 mil-
lion of the acquisition price allocated to goodwill for
accounting purposes, therefore, is economically at-
tributable to either or both the in-process technology
and the workforce. That moots the potential issue
under the acquisition price method of the reliabil-
ity of valuation of assets not to be compensated by
PCTs, since there are no such assets. Assuming the
acquisition price method is otherwise the most reli-
able method, the aggregate value of Company X’s
in-process technology and workforce is the full ac-
quisition price of $100 million. Accordingly, the ag-
gregate value of the arm’s length PCT Payments due
from FSub to USP for the external contributions con-
sisting of the RT Rights in Company X’s in-process
technology and workforce will equal $100 million
multiplied by FSub’s RAB share.
Example 2. (i) The facts are the same as inExam-
ple 1, except that Company X is a mature software
business in the United States with a successful cur-
rent generation of software that it markets under a
recognized trademark, in addition to having the re-
search team and new generation software in process
that could significantly enhance the programs being
developed under USP’s and FSub’s CSA. USP con-
tinues Company X’s existing business and integrates
the research team and the in-process technology into
the efforts under its CSA with FSub. For accounting
purposes, the $100 million acquisition price for ac-
quiring Company X is allocated $50 million to exist-
ing software and trademark, $25 million to in-process
technology and research workforce, and the residual
$25 million to goodwill and going concern value.
(ii) In this case an analysis of the facts indicates
a likelihood, consistent with the allocation under the
accounting treatment (although not necessarily in
the same amount), of goodwill and going concern
value economically attributable to the existing U.S.
software business rather than to the external contri-
butions consisting of the RT Rights in the in-process
technology and research workforce. Accordingly,
further consideration must be given to the extent to
which these circumstances reduce the relative relia-
bility of the acquisition price method in comparison
to other potentially applicable methods for evaluating
the PCT Payment.
Example 3.(i) USP, a U.S. corporation and FSub,
a wholly-owned foreign subsidiary of USP, enter into
a CSA in Year 1 to develop Product A. Company
Y is an uncontrolled corporation that owns Technol-
ogy X that is critical to the development of Product
A. Company Y currently markets Product B, which
is dependent on Technology X. USP is solely inter-
ested in acquiring Technology X, but is only able to
do so through the acquisition of Company Y in its en-
tirety for $200 million in an uncontrolled transaction
in Year 2. For accounting purposes, the acquisition
price is allocated as follows: $120 million to Prod-
uct B and the underlying Technology X, $30 million
to trademark and other marketing intangibles, and the
residual $50 million to goodwill and going concern.
After the acquisition of Company Y, Technology X
is used to develop Product A. No other part of Com-
pany Y is utilized in any manner. Product B is discon-
tinued and accordingly, the accompanying marketing
intangibles become worthless. None of the previous
employees of Company Y are retained.
(ii) The Technology X of Company Y acquired
by USP is reasonably anticipated to contribute to de-
veloping cost shared intangibles and is therefore an
external contribution for which FSub must compen-
sate USP as part of a PCT. Although for account-
ing purposes a significant portion of the acquisition
price of Company Y was allocated to items other than
Technology X, the facts demonstrate that USP had
no intention of using and therefore placed no eco-
nomic value on any part of Company Y other than
Technology X. If USP was willing to pay $200 mil-
lion for Company Y solely for purposes of acquiring
Technology X, then assuming the acquisition price
method is otherwise the most reliable method, the
value of Technology X is the full $200 million ac-
quisition price. Accordingly, the value of the arm’s
length PCT Payment due from FSub to USP for the
external contribution consisting of the RT Rights in
Technology X will equal $200 million multiplied by
FSub’s RAB share.
(viii)Valuation consistent with the in-
vestor model—(A)In general. The val-
uation of the amount charged in a PCT
must be consistent with the assumption
that, as of the date of the PCT, each con-
trolled participant’saggregate net invest-
ment in developing cost shared intangibles
pursuant to the CSA, attributable to both
external contributions and cost contribu-
tions, is reasonably anticipated to earn a
rate of return equal to the appropriate dis-
count rate, determined following the prin-
ciples set forth in paragraph (g)(2)(vi) of
this section, over the entire period of de-
veloping and exploiting the cost shared in-
tangibles. If the cost shared intangibles
themselves are reasonably anticipated to
contribute to developing other intangibles,
then the period in the preceding sentence
includes the period of developing and ex-
ploiting such indirectly benefited intangi-
bles.
(B)Example. The following example
illustrates the principles of this paragraph
(g)(2)(viii):
Example. (i) P, a U.S. corporation, has developed
a software program, DEF, which applies certain algo-
rithms to reconstruct complete DNA sequences from
partially-observed DNA sequences. S is a wholly-
owned foreign subsidiary of P. P and S enter into a
CSA to develop a new generation of genetic tests,
GHI, based in part on the use of DEF which is there-
fore an external contribution of P for which compen-
sation is due from S pursuant to a PCT. S makes no
external contributions to the CSA. GHI sales are pro-
jected to commence two years after the inception of
the CSA, which is on the first day of Year 1, and then
to continue for eight more years. P and S project that
GHI will be replaced by a new generation of genetic
testing based on technology unrelated to DEF or GHI
at the end of Year 10.
(ii)ForpurposesofvaluingthePCTforP’s
external contribution of DEF to the CSA, P and
S apply a type of residual profit split method that
is not described in paragraph (g)(7) of this section
and which, accordingly, constitutes an unspecified
method. See paragraph (g)(7)(i)(last sentence) of
this section. The principles of this paragraph (g)(2)
apply to any method for valuing a PCT, including the
unspecified method used by P and S.
(iii) Under the method employed by P and S, in
each Year, a portion of the income from sales of GHI
in S’s territory is allocated to certain routine contri-
butions made by S. The residual of the profit or loss
from GHI sales in S’s territory after the routine al-
location step is divided between the controlled par-
ticipantspro ratato their capital stocks allocable to
S’s territory. Each controlled participant’s capital
stock is computed by growing and amortizing (in the
case of P) its historical expenditures regarding DEF
allocable to S’s territory and (in the case of S) its
ongoing cost contributions towards developing GHI.
The amortization of the capital stocks is effected on
a straight-line basis over an assumed four-year life
for the relevant expenditures. The capital stocks are
grown using an assumed growth factor which P and S
consider to be appropriate. Thus, the residual profit
or loss from sales of GHI in S’s territory is divided
2005–40 I.R.B.656October 3, 2005

between P and Spro ratato P’s capital stock in DEF
attributable to S’s territory and to S’s capital stock
from its cost contributions.
(iv) The assumption that all expenditures amor-
tize on a straight-line basis over four years does not
appropriately reflect the principle that as of the date of
the PCT regarding DEF, every contribution to the de-
velopment of GHI, including DEF is reasonably an-
ticipated to have value throughout the entire period of
exploitation of GHI as projected to continue through
Year 10. Under this method as applied by P and S,
P’s capital stock in DEF, and therefore the amount of
profit in S’s territory allocated to P as a PCT Pay-
ment from S, will decrease every year. After Year 4,
P’s capital stock in DEF will necessarily be $0. Thus,
under this method, P will receive none of the residual
profit or loss from GHI sales in S’s territory after Year
4 as a PCT Payment. As a result of this limitation of
the PCT Payments to be made by S, the return to S’s
aggregate investment in the CSA is anticipated to be
significantly higher than the appropriate discount rate
for the CSA. This is not consistent with the investor
model principle that S should anticipate a return to its
aggregate investment in the CSA equal to the appro-
priate discount rate over the entire period of devel-
oping and exploiting GHI. The inconsistency of the
method with the investor model materially lessens its
reliability for purposes of a best method analysis. See
§1.482–1(c)(2)(ii)(B).
(ix)Coordination of best method rule
and form of payment. A method described
in paragraph (g)(1) of this section eval-
uates the arm’s length amount charged
in a PCT in terms of a form of payment
(method payment form). For example,
the method payment form for the income
method described in paragraph (g)(4)(iii)
or (iv) of this section is payment contin-
gent on the exploitation of cost shared
intangibles by the PCT Payor, and the
method payment form for the market
capitalization method is lump sum pay-
ment. The method payment form may
not necessarily correspond to the form
of payment specified pursuant to para-
graphs (b)(3)(vi)(A) and (k)(2)(ii)(l) of
this section (specified payment form).
The determination under §1.482–1(c) of
the method that provides the most reliable
measure of an arm’s length result is to
be made without regard to whether the
respective method payment forms under
the competing methods correspond to the
specified payment form. If the method
payment form of the method determined
under §1.482–1(c) to provide the most
reliable measure of an arm’s length result
differs from the specified payment form,
then the conversion from such method
payment form to such specified payment
form will be made on a reasonable basis to
the satisfaction of the Commissioner. For
purposes of the preceding sentence, if the
method described in the documentation
by the controlled participants pursuant to
paragraph (k)(2)(ii)(J) of this section is
determined under §1.482–1(c) to provide
the most reliable measure of an arm’s
length result, then the Commissioner will
give due consideration whether the con-
version from the method payment form to
the specified payment form was made by
the controlled participants on a reasonable
basis.
(x)Coordination of the valuations of
prior and subsequent PCTs—(A)In gen-
eral. In cases where PCTs are required on
different dates, coordination of the valu-
ations of the prior and subsequent PCTs
must be effected pursuant to a method that
provides the most reliable measure of an
arm’s length result. Depending on the
facts and circumstances, such as whether
the external contributions that were the
subject of the prior and subsequent PCTs
were nonroutine contributions, an ap-
proach which may be appropriate would
be to determine PCT Payments both for
the prior and subsequent PCTs going for-
ward from the date of the subsequent PCT
pursuant to a residual profit split method,
as described in paragraph (g)(7) of this
section. Such application of the residual
profit split method would include as non-
routine contributions all of the following:
the external contribution(s) that were the
subject of the prior PCT(s), the exter-
nal contribution that is the subject of the
subsequent PCT, and the interests of the
controlled participants in the incremental
cost shared intangible development result-
ing from the development activities under
the CSA. Paragraph (g)(2)(x)(B) of this
section specifies the appropriate coordi-
nation with a prior PCT in the case of a
subsequent PCT the subject of which is a
PFA.
(B)Coordination with regard to PFAs.
PCT Payments for a subsequent PCT that
is derived from a PFA are determined in-
dependently of any prior PCTs. Such PCT
Payments will be treated, for purposes
of the application of the method used for
evaluating a prior PCT, the same as IDCs
the actual amounts of which may not cor-
respond to those projected on the date of
the prior PCT. A divergence between ac-
tual and anticipated IDCs does not require
alteration in the application of the method
used to value PCT Payments. Similarly, a
subsequent PCT derived from a PFA will
not require alteration in the application of
the method used to value PCT Payments
forapriorPCT.
(xi)Proration of PCT Payments to the
extent allocable to other business activ-
ities. If a resource or capability that is
the subject of a PCT is reasonably antici-
pated to contribute both to developing or
exploiting cost shared intangibles and to
other business activities of the PCT Payee
(other than exploitingan existing intangi-
ble without further development), then to
the extent it can be demonstrated that a
portion of the value of the relevant PCT
Payments otherwise determined under this
section is attributable to such other busi-
ness activities, the PCT Payments must be
prorated. Such proration will be done on a
reasonable basis in proportion to the rela-
tive economic value, as of the date of the
PCT, reasonably anticipated to be derived
from the resource orcapability by the CSA
Activity as compared to such other busi-
ness activities of the PCT Payee. In the
case of an aggregate valuation done under
the principles of paragraph (g)(2)(v) of this
section that includes payment for rights to
exploit an existing intangible without fur-
ther development, the prorated aggregate
payments must take into account the eco-
nomic value attributable to such exploita-
tion rights as well. For purposes of the best
method rule under §1.482–1(c), the relia-
bility of the analysis under a method that
requires proration pursuant to this para-
graph is reduced relative to the reliability
of an analysis under a method that does not
require proration.
(3)Comparable uncontrolled transac-
tion method. The comparable uncontrolled
transaction (CUT) method described in
§1.482–4(c), and the arm’s length charge
described in §1.482–2(b)(3)(first sen-
tence) based on a comparable uncon-
trolled transaction, may be applied to
evaluate whether the amount charged in
a PCT is arm’s length by reference to
the amount charged in a comparable un-
controlled transaction. When applied in
the manner describedin §1.482–4(c), or
where a comparable uncontrolled trans-
action provides the most reliable measure
of the arm’s length charge described in
§1.482–2(b)(3)(first sentence), the CUT
method, or the arm’s length charge in the
comparable uncontrolled transaction, will
typically yield an arm’s length total value
October 3, 20056572005–40 I.R.B.

for the external contribution that is the
subject of the PCT. That value must then
be multiplied by each PCT Payor’s respec-
tive RAB share in order to determine the
arm’s length PCT Payment due from each
PCT Payor. The reliability of a CUT that
yields a value for the external contribution
only in the PCT Payor’s territory will be
reduced to the extent that value is not con-
sistent with the total worldwide value of
the external contribution multiplied by the
PCT Payor’s RAB share.
(4)Income method—(i)In general.
The income method evaluates whether the
amount charged in a PCT is arm’s length
by reference to the controlled participants’
realistic alternatives to entering into a
CSA.
(ii)Determination of arm’s length
charge—(A)In general.Underthis
method, the arm’s length charge for a PCT
Paymentwillbeanamountsuchthata
controlled participant’s present value, as
of the date of the PCT, of entering into a
CSA equals the present value of its best
realistic alternative. Paragraphs (g)(4)(iii)
and (iv) of this section describe two spe-
cific applications of the income method,
but do not exclude other possible applica-
tions of this method.
(B)Example. The following example
illustrates the principles of this paragraph
(g)(4)(ii):
Example. (i) USP, a U.S. manufacturer, has devel-
oped a new, light weight fabric for sleeping bags. In
Year 1, USP enters into a CSA with its wholly-owned
foreign subsidiary, FSub, to develop an improved ver-
sion of this fabric. Under the CSA, USP will own the
rights to exploit improved versions of the fabric in the
United States and FSub will own the rights to exploit
improvements in the rest of the world (ROW). The
rights to further develop the fabric are reasonably an-
ticipated to contribute to the development of future
improved versions and therefore the RT Rights in the
fabric are external contributions for which compensa-
tion is due pursuant to a PCT. USP does not transfer
the right to exploit its current fabric to FSub. FSub
does not furnish any external contributions. If USP
did not participate in the CSA, its best realistic al-
ternative would be to develop future versions of the
fabric on its own, exploit those versions in the United
States and license such versions for exploitation out-
side the United States to FSub. In Year 1, USP es-
timates that its present value of this alternative (in-
cluding arm’s length royalties on sales in the ROW)
is $100 million. Under the CSA, USP projects U.S.
sleeping bag sales with improved versions of the fab-
ric to amount to $80 million (present value in Year
1). The costs (other than IDCs) plus the routine re-
turn to such costs associated with the U.S. sales are
anticipated to be $10 million. USP’s anticipated cost
contributions under the CSA are $10 million (present
value in Year 1). FSub projects that in the ROW
future sales should amount to $100 million (present
value in Year 1).
(ii) An arm’s length contingent PCT Payment un-
der the income method is a sales-based royalty at a
rate, p, such that the present value to USP of the best
realistic alternative is equal to the present value to
USP of participating in the CSA. In other words, the
rate is such that $100 million (value of licensing al-
ternative) = $80 million (anticipated U.S. sales) - $10
million (anticipated costs, other than IDCs, plus rou-
tine return) - $10 million (anticipated cost contribu-
tion) + (p * $100 million (anticipated ROW sales)),
or 40%. Accordingly, FSub should pay USP a roy-
alty of 40% of actual ROW sales annually when the
two begin to exploit future generations of the fabric.
(iii)Application of income method us-
ingaCUT—(A)In general. This applica-
tion of the income method is typically used
in cases where only one controlled partici-
pant furnishes nonroutine contributions, as
described in paragraph (g)(7)(iii)(C)(1)of
this section. This application assumes that
the best reasonable alternative of the PCT
Payee to entering into the CSA would be to
develop the cost shared intangibles on its
own, bearing all the IDCs itself, and then
to license the cost shared intangibles to the
other controlled participants.
(B)Determination of arm’s length
charge—(1)In general. An arm’s length
PCT Payment under this application of
the income method is represented as an
applicable rate on sales from exploiting
the cost shared intangibles, determined as
ofthedateofthePCT.
(2)Applicable rate. The applicable rate
is equal to the alternative rate less the cost
contribution adjustment.
(3)Alternative rate. The alternative
rate is the constant rate the PCT Payee
would charge an uncontrolled licensee
over the period the cost shared intangibles
are anticipated to be exploited if the PCT
Payee had developed the cost shared in-
tangibles on its own and licensed them to
the uncontrolled licensee. The alternative
rate is determined using the comparable
uncontrolled transaction method, as de-
scribed in §1.482–4(c)(1) and (2).
(4)Cost contribution adjustment.The
cost contribution adjustment is equal to
a fraction, the numerator of which is the
present value of the PCT Payor’s total
anticipated cost contributions and the de-
nominator of which is the present value
of the PCT Payor’s total anticipated sales
from exploiting the cost shared intangi-
bles.
(C)Example. The following example
illustrates the principles of this paragraph
(g)(4)(iii):
Example. (i) USP, a software company, has devel-
oped version 1.0 of a new software application which
it is currently marketing. In Year 1 USP enters into a
CSA with its wholly-owned foreign subsidiary, FS,
to develop future versions of the software applica-
tion. Under the CSA, USP will have the rights to ex-
ploit the future versions in the United States, and FS
will have the rights to exploit them in the rest of the
world (ROW). The future rights in version 1.0, and
USP’s development team, are reasonably anticipated
to contribute to the development of future versions
andthereforetheRTRightsinversion1.0areexter-
nal contributions for which compensation is due from
FS as part of a PCT. USP does not transfer the cur-
rent exploitation rights in version 1.0 to FS. FS does
not furnish any external contributions. FS anticipates
sales of $100 million (present value in Year 1) in its
territory and anticipates cost contributions of $40 mil-
lion (present value in Year 1). The arm’s length rate
USP would have charged an uncontrolled licensee for
a license of future versions of the software had USP
further developed version 1.0 on its own is 60%, as
determined under the comparable uncontrolled trans-
action method in §1.482–4(c).
(ii) An arm’s length contingent PCT Payment un-
der the income method is an applicable rate equal
to the alternative rate less the cost contribution ad-
justment. In this case the alternative rate is 60%,
the arm’s length rate determined under §1.482–4(c).
The cost contribution adjustment is 40%, the present
value to FS of its anticipated cost contribution over
the present value of its anticipated sales of future ver-
sions of the software, that is, $40 million/$100 mil-
lion. The applicable rate, which represents an arm’s
length contingent PCT Payment, payable by the FS to
USP on all actual ROW sales of the future versions of
the software therefore is 20%, which is equal to the
alternative rate of 60% less the cost contribution ad-
justment of 40%.
(iv)Application of income method us-
ing CPM—(A)In general. This appli-
cation of the income method is typically
used in cases where only one controlled
participant furnishes nonroutine contribu-
tions. Under this application, the present
value of the anticipated PCT Payments is
equal to the present value, as of the date
of the PCT, of the PCT Payor’s anticipated
profit from developing and exploiting cost
shared intangibles. This PCT Payment en-
sures that PCT Payors who do not furnish
any external contributions subject to a PCT
receive an appropriate ex ante risk adjusted
return on their investment in the CSA.
(B)Determination of arm’s length
charge based on sales—(1)In general.
An arm’s length PCT Payment under this
application of the income method is repre-
sented as an applicable rate on sales from
exploiting the cost shared intangibles, de-
termined as of the date of the PCT.
2005–40 I.R.B.658October 3, 2005

(2)Applicable rate. The applicable rate
is equal to the alternative rate less the cost
contribution adjustment.
(3)Alternative rate. The alternative
rate is determined using the comparable
profits method described in §1.482–5 and
is estimated as a fraction. The numera-
tor of the fraction is the present value of
the PCT Payor’s total anticipated territo-
rial operating profit, as defined in para-
graph (j)(1)(vi) of this section, reduced by
a market return for the routine contribu-
tions (other than cost contributions) to the
relevant business activity in the relevant
territory. The denominator of the frac-
tion is the discounted present value of the
PCT Payor’s total anticipated sales from
exploiting the cost shared intangibles.
(4)Cost contribution adjustment.The
cost contribution adjustment is equal to
a fraction the numerator of which is the
present value of the PCT Payor’s total
anticipated cost contributions and the de-
nominator of which is the present value
of the PCT Payor’s total anticipated sales
from exploiting the cost shared intangi-
bles.
(C)Determination of arm’s length
charge based on profit—(1)In general.
An arm’s length PCT Payment under this
application of the income method may
also be represented as an applicable rate
on territorial operating profit, as defined
in paragraph (j)(1)(vi) of this section, re-
duced by a market return for the routine
contributions (otherthan cost contribu-
tions) to the relevant business activity in
the relevant territory. This is done follow-
ing the calculations described in paragraph
(g)(4)(iv)(B) of this section, substituting
anticipated territorialoperating profit, re-
duced by a market return for the routine
contributions (otherthan cost contribu-
tions) to the relevant business activity in
the relevant territory, wherever anticipated
sales appear in the calculations.
(2)Alternative rate.Substitutingter-
ritorial operating profits, reduced by a
market return for the routine contribu-
tions (other than cost contributions) to the
relevant business activity in the relevant
territory, for sales in the calculation of the
alternative rate results in a fraction with
both a numerator and denominator equal
to the present value of the PCT Payor’s to-
tal anticipated territorial operating profit,
as defined in paragraph (j)(1)(vi) of this
section, reduced by a market return for
the routine contributions (other than cost
contributions) to the relevant business ac-
tivity in the relevant territory. Therefore
the alternative rate under this application
is 1, or 100%.
(3)Cost contribution adjustment.Sub-
stituting territorial operating profit, re-
duced by a market return for the routine
contributions (otherthan cost contribu-
tions) to the relevant business activity
in the relevant territory, for sales results
in a cost contribution adjustment equal
to a fraction the numerator of which is
the present value of the PCT Payor’s
total anticipated cost contributions and
the denominator of which is the present
value of the PCT Payor’s total anticipated
territorial operating profit, as defined in
paragraph (j)(1)(vi) of this section, re-
duced by a market return for the routine
contributions (otherthan cost contribu-
tions) to the relevant business activity in
the relevant territory.
(D)Example. The following example
illustrates the principles of this paragraph
(g)(4)(iv):
Example. (i) USP, a U.S. pharmaceutical com-
pany, invests in research and development to begin
developing a vaccine for disease K. In Year 1, USP
enters into a CSA with its wholly-owned foreign sub-
sidiary, FS, to complete the development of the vac-
cine. Under the CSA, USP will have the rights to
exploit the vaccine in the United States, and FS will
have the rights to exploit it in the rest of the world.
The partially developed vaccine owned by USP, and
USP’s development team, are reasonably anticipated
to contribute to the development of the final vaccine
and therefore the RT Rights in the vaccine and the de-
velopment team are external contributions for which
compensation is due from FS as part of a PCT. FS
does not furnish any external contributions. The to-
tal anticipated IDCs under the CSA are $100 million
(in Year 1 dollars). USP and FS each have total pro-
jected sales of $100 million (in Year 1 dollars) of the
vaccine, which they use as the basis for determining
RAB shares. Accordingly, they divide the develop-
ment costs based on 50/50 RAB shares, $50 million
(inYear1dollars)paidbyeachparticipant. Based
on an analysis under the comparable profits method
under §1.482–5, FS’s anticipated territorial operating
profit, as reduced by a market return for the its routine
contributions to exploiting the vaccine in its territory,
is $80 million (in Year 1 dollars).
(ii) An arm’s length contingent PCT Payment
based on territorial sales under the income method
is an applicable rate equal to the alternative rate
less the cost contribution adjustment. In this case
the alternative rate is 80% ($80 million territorial
operating profit/$100 million sales). The cost con-
tribution adjustment is 50%, the present value to FS
of its anticipated cost contributions over the present
value of its anticipated sales of the vaccine, that is,
$50 million/$100 million. The applicable rate, which
represents an arm’s length contingent PCT Payment,
payable by FS to USP over the period the vaccine
is exploited therefore is 30%, which is equal to the
alternative rate of 80% less the cost contribution
adjustment of 50%.
(iii) An arm’s length contingent PCT Payment
based on territorial operating profits under the income
method is an applicable rate equal to the alternative
rate less the cost contribution adjustment. In this
case the alternative rate is 100% ($80 million territo-
rial operating profit /$80 million territorial operating
profit). The cost contribution adjustment is 62.5%,
the present value to FS of its anticipated cost contri-
butions over the present value of its anticipated ter-
ritorial profits from sales of the vaccine, that is, $50
million/$80 million. The applicable rate on territo-
rial operating profit, which represents an arm’s length
contingent PCT Payment, payable by FS to USP over
the period the vaccine is exploited therefore is 37.5%,
which is equal to the alternative rate of 100% less the
cost contribution adjustment of 62.5%.
(v)Routine external contributions.For
purposes of this paragraph (g)(4), any rou-
tine contributions that are external con-
tributions (routine external contributions),
the valuation and PCT Payments for which
are determined and made independently
of the income method, are treated simi-
larly to cost contributions. Accordingly,
wherever the term cost contributions ap-
pears in this paragraph (g)(4) it shall be
read to include net routine external contri-
butions. Net routine external contributions
are defined as a controlled participant’s to-
tal anticipated routine external contribu-
tions, plus its anticipated PCT Payments
to other controlled participants in respect
of their routine external contributions, mi-
nus the anticipated PCT Payments it is to
receive from other controlled participants
in respect of its routine external contribu-
tions.
(vi)Comparability and reliability con-
siderations—(A)In general.Whether
results derived from this method are the
most reliable measure of the arm’s length
result is determined using the factors de-
scribed under the best method rule in
§1.482–1(c). Thus, comparability and the
quality of data and assumptions must be
considered in determining whether this
method provides the most reliable mea-
sure of an arm’s length result. Consistent
with those considerations, the reliability of
applying the income method as a measure
of the arm’s length charge for a PCT Pay-
ment is typically less reliable to the extent
that more than one controlled participant
furnishes nonroutine contributions.
(B)Application of the income method
usingaCUT. If the income method is ap-
plied using a CUT, as described in para-
October 3, 20056592005–40 I.R.B.

graph (g)(4)(iii) of this section, any addi-
tional comparability and reliability consid-
erations stated in §1.482–4(c)(2) may ap-
ply.
(C)Application of the income method
using CPM. If the income method is ap-
plied using CPM, as described in para-
graph (g)(4)(iv) of this section, any addi-
tional comparability and reliability consid-
erations stated in §1.482–5(c) may apply.
(5)Acquisition price method—(i)In
general. The acquisition price method
applies the comparable uncontrolled
transaction method of §1.482–4(c), or
the arm’s length charge described in
§1.482–2(b)(3)(first sentence) based on
a comparable uncontrolled transaction, to
evaluate whether the amount charged in
a PCT, or group of PCTs, is arm’s length
by reference to the amount charged (the
acquisition price) for the stock or asset
purchase of an entire organization or por-
tion thereof (the target) in an uncontrolled
transaction. The acquisition price method
is ordinarily used only where substantially
all the target’s nonroutine contributions
(as described in paragraph (g)(7)(iii)(C)(1)
of this section) to the PCT Payee’s busi-
ness activities are covered by a PCT or
group of PCTs.
(ii)Determination of arm’s length
charge. Under this method, the arm’s
length charge for a PCT or group of PCTs
covering resources and capabilities of the
target is equal to the adjusted acquisition
price, as divided among the controlled
participants according to their respective
RAB shares.
(iii)Adjusted acquisition price.Thead-
justed acquisition price is the acquisition
price of the target increased by the value of
the target’s liabilities on the date of the ac-
quisition, other than liabilities not assumed
in the case of an asset purchase, and de-
creased by the value of the target’s tangi-
ble property on that date and by the value
on that date of any other resources and ca-
pabilities not covered by a PCT or group
of PCTs.
(iv)Reliability and comparabil-
ity considerations. The comparability
and reliability considerations stated in
§1.482–4(c)(2) apply. Consistent with
those considerations, the reliability of ap-
plying the acquisition price method as a
measure of the arm’s length charge for the
PCT Payment normally is reduced if —
(A) A substantial portion of the tar-
get’s nonroutine contributions to the PCT
Payee’s business activities is not required
to be covered by a PCT or group of PCTs,
and that portion of the nonroutine contri-
butions cannot reliably be valued; or
(B) A substantial portion of the target’s
assets consists of tangible property that
cannot reliably be valued.
(v)Example. The following example
illustrates the principles of this paragraph
(g)(5):
Example. USP, a U.S. corporation, and its newly
incorporated, wholly-owned foreign subsidiary (FS)
enterintoaCSAinYear1todevelopGroupZ
products. Under the CSA, USP and FS will have
the exclusive rights to exploit the Group Z products
in the U.S. and the rest of the world, respectively.
Based on RAB shares, USP will bear 60% and FS
will bear 40% of the costs incurred during the term
of the agreement. USP acquires Company X in
Year 2 for cash consideration worth $110 million.
Company X joins in the filing of a U.S. consoli-
dated income tax return with USP. Under paragraph
(j)(2)(i) of this section, Company X and USP are
treated as one taxpayer. Accordingly, the RT Rights
in any of Company X’s resources and capabilities
that are reasonably anticipated to contribute to the
development activities of the CSA will be considered
external contributions furnished by USP. Company
X’s resources and capabilities consist of its work-
force, certain technology intangibles, $15 million
of tangible property and other assets and $5 million
in liabilities. The technology intangibles, as well
as Company X’s workforce, are reasonably antici-
pated to contribute to the development of the Group
Z products under the CSAand, therefore, the RT
Rights in the technology intangibles and the work-
force are external contributions by way of a PFA for
which FS must make a PCT Payment to USP. None
of Company X’s existing intangible assets or any of
its workforce are anticipated to contribute to activi-
ties outside the CSA. Applying the acquisition price
method, the value of USP’s external contributions is
the adjusted acquisition price of $100 million ($110
million acquisition price plus $5 million liabilities
less $15 million tangible property and other assets).
FS must make a PCT Payment to USP for these
external contributions in an amount of $40 million,
which is the product of $100 million (the value of the
external contributions) and 40% (FS’s RAB share).
(6)Market capitalization method—
(i)In general. The market capitalization
method applies the comparable uncon-
trolled transaction method of §1.482–4(c),
or the arm’s length charge described in
§1.482–2(b)(3)(first sentence) based on a
comparable uncontrolled transaction, to
evaluate whether the amount charged in
a PCT, or group of PCTs, is arm’s length
by reference to the average market capi-
talization of a controlled participant (PCT
Payee) whose stock is regularly traded
on an established securities market. The
market capitalization method is ordinarily
used only where substantially all of the
PCT Payee’s nonroutine contributions (as
described in paragraph (g)(7)(iii)(C)(1)of
this section) to the PCT Payee’s business
arecoveredbyaPCTorgroupofPCTs.
(ii)Determination of arm’s length
charge. Under the market capitalization
method, the arm’s length charge for a PCT
or group of PCTs covering resources and
capabilities of the PCT Payee is equal to
the adjusted average market capitalization,
as divided among the controlled partici-
pants according to their respective RAB
shares.
(iii)Average market capitalization.The
average market capitalization is the av-
erage of the daily market capitalizations
of the PCT Payee over a period of time
beginning 60 days before the date of the
PCT and ending on the date of the PCT.
The daily market capitalization of the PCT
Payee is calculated on each day its stock
is actively traded as the total number of
shares outstanding multiplied by the ad-
justed closing price of the stock on that
day. The adjusted closing price is the daily
closing price of the stock, after adjust-
ments for stock-based transactions (divi-
dends and stock splits) and other pending
corporate (combination and spin-off) re-
structuring transactions for which reliable
arm’s length adjustments can be made.
(iv)Adjusted average market capital-
ization. The adjusted average market cap-
italization is the average market capital-
ization of the PCT Payee increased by the
value of the PCT Payee’s liabilities on the
date of the PCT and decreased by the value
on such date of the PCT Payee’s tangible
property and of any other resources and ca-
pabilities of the PCT Payee not covered by
a PCT or group of PCTs.
(v)Reliability and comparability
considerations.The comparability
and reliability considerations stated in
§1.482–4(c)(2) apply. Consistent with
those considerations, the reliability of
applying the comparable uncontrolled
transaction method using the adjusted
market capitalization of a company as a
measure of the arm’s length charge for the
PCT Payment normally is reduced if —
(A) A substantial portion of the PCT
Payee’s nonroutine contributions to its
business activities is not required to be
covered by a PCT or group of PCTs, and
2005–40 I.R.B.660October 3, 2005

that portion of the nonroutine contribu-
tions cannot reliably be valued;
(B) A substantial portion of the PCT
Payee’s assets consists of tangible prop-
erty that cannot reliably be valued; or
(C) Facts and circumstances demon-
strate the likelihood of a material diver-
gence between the average market capi-
talization of the PCT Payee and the value
of its resources and capabilities for which
reliable adjustments cannot be made.
(vi)Examples. The following examples
illustrate the principles of this paragraph
(g)(6):
Example 1. (i) USP, a publicly traded U.S. com-
pany, and its newly incorporated wholly-owned for-
eign subsidiary (FS) enter into a CSA on Date 1 to
develop software. Under the CSA, USP and FS will
have the exclusive rights to exploit all future gener-
ations of the software in the United States and the
rest of the world, respectively. Based on RAB shares,
USP will bear 70% and FS will bear 30% of the costs
incurred during the term of the CSA. USP’s assem-
bled team of researchers and its entire existing and
in-process software are reasonably anticipated to con-
tribute to the development of the software under the
CSA and the RT Rights in the research team and ex-
isting and in-process software are, therefore, exter-
nal contributions for which compensation is due from
FS. USP separately enters into a license agreement
with FS for make-and-sell rights for all existing soft-
ware in the rest of the world. This license of current
make-and-sell rights is a transaction that is governed
by §1.482–4. However, after analysis, it is deter-
mined that the PCT Payments and the arm’s length
payments for the make-and-sell license may be most
reliably determined in the aggregate using the market
capitalization method, under principles described in
paragraph (g)(2)(v) of this section.
(ii) On Date 1, USP had an average market capi-
talization of $205 million, tangible property and other
assets that can be reliably valued worth $5 million
and no liabilities. Applying the market capitaliza-
tion method, the aggregate value of USP’s external
contributions and the make-and-sell rights in its ex-
isting software is $200 million ($205 million average
market capitalization of USP less $5 million of tangi-
ble property and other assets). The total arm’s length
value of the PCT Payments and license payments FS
must make to USP for the external contributions and
current make-and-sell rights is $60 million, which is
the product of $200 million (the value of the external
contributions and the make-and-sell rights) and 30%
(FS’s share of anticipated benefits of 30%).
Example 2. The facts are the same asExam-
ple 1except that USP also makes significant nonrou-
tine contributions that are difficult to value to several
other mature business divisions it operates that are not
reasonably anticipated to contribute to the software
development that is the subject of the CSA and, there-
fore, are not external contributions and, accordingly,
are not required to be covered by a PCT. The reliabil-
ity of using the market capitalization method to deter-
mine the value of USP’s external contributions to the
CSA is significantly reduced in this case because it
would require adjusting USP’s average market cap-
italization to account for the significant nonroutine
contributions that are notrequired to be covered by
aPCT.
(7)Residual profit split method—(i)In
general. The residual profit split method
evaluates whether the allocation of com-
bined operating profit or loss attributable
to one or more external contributions sub-
ject to a PCT is arm’s length by reference
to the relative value of each controlled par-
ticipant’s contribution to that combined
operating profit or loss. The combined
operating profit or loss must be derived
from the most narrowly identifiable busi-
ness activity of the controlled participants
for which data are available that include
the developing and exploiting of cost
shared intangibles (relevant business ac-
tivity). The residual profit split method
may not be used where only one controlled
participant makes significant nonroutine
contributions to the development and ex-
ploitation of the cost shared intangibles.
The provisions of §1.482–6 shall apply
to CSAs only to the extent provided and
as modified in this paragraph (g)(7). Any
other application to a CSA of a residual
profit method not described below will
constitute an unspecified method for pur-
poses of sections 482 and 6662(e) and the
regulations thereunder.
(ii)Appropriate share of profits and
losses. The relative value of each con-
trolled participant’s contribution to the
success of the relevant business activ-
ity must be determined in a manner that
reflects the functionsperformed, risks as-
sumed, and resources employed by each
participant in the relevant business ac-
tivity, consistent with the comparability
provisions of §1.482–1(d)(3). Such an
allocation is intended to correspond to
the division of profit or loss that would
result from an arrangement between un-
controlled taxpayers, each performing
functions similar to those of the various
controlled participants engaged in the rele-
vant business activity. The profit allocated
to any particular controlled participant is
not necessarily limited to the total operat-
ing profit of the group from the relevant
business activity. For example, in a given
year, one controlled participant may earn a
profit while another controlled participant
incurs a loss. In addition, it may not be as-
sumed that the combined operating profit
or loss from the relevant business activity
should be shared equally, or in any other
arbitrary proportion.
(iii)Profit split—(A)In general.
Under the residual profit split method,
each controlled participant’s territorial
operating profit or loss, as defined in
paragraph (j)(1)(vi) of this section, is allo-
cated between the controlled participants
that each furnish significant nonroutine
contributions to the relevant business
activity in that territory following the
three step process set forth in paragraphs
(g)(7)(iii)(B) and (C) of this section.
(B)Allocate income to routine contri-
butions other than cost contributions.The
first step allocates an amount of income
to each controlled participant that is sub-
tracted from its territorial operating profit
or loss to provide a market return for the
controlled participant’s routine contribu-
tions (other than cost contributions) to the
relevant business activity in its territory.
Routine contributions are contributions of
the same or a similar kind to those made by
uncontrolled taxpayers involved in similar
business activities for which it is possible
to identify market returns. Routine contri-
butions ordinarily include contributions of
tangible property, services and intangibles
that are generally owned or provided by
uncontrolled taxpayers engaged in sim-
ilar activities. A functional analysis is
required to identify these contributions
according to the functions performed,
risks assumed, and resources employed
by each of the controlled participants.
Market returns for the routine contribu-
tions should be determined by reference
to the returns achieved by uncontrolled
taxpayers engaged in similar activities,
consistent with the methods described
in §§1.482–3, 1.482–4, and 1.482–5, or
with the arm’s length charge described in
§1.482–2(b)(3)(first sentence) based on a
comparable uncontrolled transaction.
(C)Allocate residual profit—(1)In
general. The allocation of income to each
controlled participant’s routine contribu-
tions in the first step will not reflect profit
or loss attributable to that controlled par-
ticipant’s cost contributions, nor reflect the
profit or loss attributable to any controlled
participant’s nonroutine contributions to
the relevant business activity. Nonroutine
contributions include nonroutine external
contributions, and other nonroutine con-
tributions, to the relevant business activ-
ity in the relevant territory. The residual
territorial profit or loss after the allocation
of income in the first step in paragraph
October 3, 20056612005–40 I.R.B.

(g)(7)(iii)(B) of this section is further al-
located under the second and third steps in
paragraphs (g)(7)(iii)(C)(2)and(3)ofthis
section.
(2)Cost contribution share of residual
profit or loss. Under the second step, a
portion of each controlled participant’s
residual territorial profit or loss after the
first step allocation is allocated to that
controlled participant’s cost contributions
(cost contribution share). A controlled
participant’s cost contribution share is
equal to the following fraction of such
residual territorial profit or loss. The nu-
merator is the present value, determined
as of the relevant date, of the summa-
tion, over the entire period of developing
and exploiting cost shared intangibles, of
the total value of such controlled partici-
pant’s total anticipated cost contributions.
The denominator is the present value, de-
termined as of the relevant date, of the
summation, over the same period, of such
controlled participant’s total anticipated
territorial operating profits, as defined in
paragraph (j)(1)(vi) of this section, re-
duced by a market return for the routine
contributions (otherthan cost contribu-
tions) to the relevant business activity in
the relevant territory. For these purposes,
the relevant date is the date of the PCTs.
(3)Nonroutine contribution share of
residual profit or loss.Underthethird
step, the remaining share of each con-
trolled participant’s residual territorial
profit or loss after thefirst and second step
allocations generally should be divided
among all of the controlled participants
based upon the relative value, determined
as of the date of the PCTs, of their nonrou-
tine contributions to the relevant business
activity in the relevant territory. The rela-
tive value of the nonroutine contributions
of each controlled participant may be mea-
sured by external market benchmarks that
reflect the fair market value of such non-
routine contributions. Alternatively, the
relative value of nonroutine contributions
may be estimated by the capitalized cost of
developing the nonroutine contributions
and updates, as appropriately grown or
discounted so that all contributions may
be valued on a comparable dollar basis
as of the same date. If the nonroutine
contributions by a controlled participant
are also used in other business activities
(such as the exploitation of make-or-sell
rights described in paragraph (c) of this
section), an allocation of the value of the
nonroutine contributions must be made on
a reasonable basis among all the business
activities in which they are used in propor-
tion to the relative economic value that the
relevant business activity and such other
business activities are anticipated to derive
over time as the result of such nonroutine
contributions.
(4)Determination of PCT Payments.
Any amount of a controlled participant’s
territorial operating profit or loss that is al-
located to another controlled participant’s
external contributionsto the relevant busi-
ness activity in the relevant territory under
the third step represents the amount of the
PCT Payment due to that other controlled
participant for such external contributions.
(5)Routine external contributions.For
purposes of this paragraph (g)(7), routine
external contributions, the valuation and
PCT Payments for which are determined
and made independently of the residual
profit split method, are treated similarly
to cost contributions. Accordingly, wher-
ever used in this paragraph (g)(7), the term
routine contribution shall not be read to
include routine external contributions and
the term cost contribution shall be read to
include net routine external contributions,
as defined in paragraph (g)(4)(v) of this
section.
(iv)Comparability and reliability con-
siderations—(A)In general.Whether
results derived from this method are the
most reliable measure of the arm’s length
result is determined using the factors de-
scribed under the best method rule in
§1.482–1(c). Thus, comparability and
the quality of data and assumptions must
be considered in determining whether this
method provides the most reliable measure
of an arm’s length result. The application
of these factors to the residual profit split
in the context of the relevant business
activity of developing and exploiting cost
shared intangibles is discussed in para-
graphs (g)(7)(iv)(B), (C), and (D) of this
section.
(B)Comparability. The first step of the
residual profit split relies on market bench-
marks of profitability. Thus, the compa-
rability considerations that are relevant for
the first step of the residual profit split are
those that are relevant for the methods that
are used to determine market returns for
the routine contributions.
(C)Data and assumptions. The relia-
bility of the results derived from the resid-
ual profit split is affected by the quality of
the data and assumptions used to apply this
method. In particular, the following fac-
tors must be considered —
(1) The reliability of the allocation of
costs, income, and assets between the rel-
evant business activity and the controlled
participants’ other activities will affect the
reliability of the determination of the ter-
ritorial operating profit and its allocation
among the controlled participants. See
§1.482–6(c)(2)(ii)(C)(1);
(2) The degree of consistency between
the controlled participants and uncon-
trolled taxpayers in accounting practices
that materially affect the items that de-
termine the amount and allocation of
operating profit affects the reliability of
the result. See §1.482–6(c)(2)(ii)(C)(2);
and
(3) The reliability of the data used and
the assumptions made in valuing the non-
routine contributions by the controlled par-
ticipants. In particular, if capitalized costs
of development are used to estimate the
value of intangible property, the reliabil-
ity of the results is reduced relative to the
reliability of other methods that do not re-
quire such an estimate, for the following
reasons. In any given case, the costs of de-
veloping the intangible may not be related
to its market value. In addition, the calcu-
lation of the capitalized costs of develop-
ment may require the allocation of indirect
costs between the relevant business activ-
ity and the controlled participant’s other
activities, which may affect the reliability
of the analysis.
(D)Other factors affecting reliability.
Like the methods described in §§1.482–3,
1.482–4, and 1.482–5, or the arm’s length
charge described in §1.482–2(b)(3) (first
sentence) based on a comparable uncon-
trolled transaction, the first step of the
residual profit split relies exclusively on
external market benchmarks. As indi-
cated in §1.482–1(c)(2)(i), as the degree
of comparability between the controlled
participants and uncontrolled transactions
increases, the relative weight accorded the
analysis under this method will increase.
In addition, to the extent the allocation of
profits in the third step is not based on ex-
ternal market benchmarks, the reliability
of the analysis will be decreased in relation
to an analysis under a method that relies
2005–40 I.R.B.662October 3, 2005

on market benchmarks. Finally, the reli-
ability of the analysis under this method
may be enhanced by the fact that all the
controlled participants are evaluated under
the residual profit split. However, the reli-
ability of the results of an analysis based
on information from all the controlled
participants is affected by the reliability
of the data and the assumptions pertaining
to each controlled participant. Thus, if
the data and assumptions are significantly
more reliable with respect to one of the
controlled participants than with respect
to the others, a different method, focusing
solely on the results of that party, may
yield more reliable results.
(v)Example. The following example
illustrates the principles of this paragraph
(g)(7):
Example. (i) USP, a U.S. nanotech company, has
partially developed technology for nanomotors which
are used to provide mobility for nanodevices. At the
same time, USP’s wholly-owned subsidiary, FS, a
foreign nanotech company, has partially developed
technology for nanosensors which provide sensing
capabilities for nanodevices. At the beginning of
Year 1, USP enters into a CSA with FS to develop
NanoBuild, a technology which will be used to build
a wide range of fully functioning nanodevices. The
partially developed nanomotor and nanosensor tech-
nologies owned by USP and FS, respectively, are
reasonably anticipated to contribute to the develop-
ment of NanoBuild and therefore the RT Rights in
the nanomotor and nanosensor technologies consti-
tute external contributions of USP and FS for which
compensation is due under PCTs. Under the CSA,
USP will have the right to exploit NanoBuild in the
United States, while FS will have the right to exploit
NanoBuild in the rest of the world. USP’s and FS’s
RAB shares are 40% and 60% respectively.
(ii) The present value of the total projected IDCs
for the CSA is $10 billion (as of the date of the PCTs).
Based on RAB shares, USP expects to bear 40%, or
$4 billion, of these IDCS and FS expects to bear 60%,
or $6 billion. For accounting purposes, USP and FS
project a combined operating profit from exploita-
tion of the NanoBuild of $11 billion (in Year 1 dol-
lars), taking into account the $10 billion of projected
IDCs. However, for purposes of applying the resid-
ual profit split method, combined operating profit is
determined without taking into account IDCs. There-
fore, USP and FS redetermine their combined oper-
ating profits for purposes of the residual profit split
method to equal $21 billion (adding $10 billion of
IDCs back to the accounting profit of $11 billion).
Of this amount, 40% or $8.4 billion is expected to be
generated by USP in the U.S. and 60% or $12.6 bil-
lion is expected to be generated by FS in the rest of
the world.
(iii) USP and FS each undertake routine distribu-
tion activities in their respective markets that consti-
tute routine contributions to the relevant business ac-
tivity of exploiting NanoBuild. They estimate that
the total market return (costs plus a market return
on those costs) on these routine contributions will
amount to $1 billion, (in Year 1 dollars). Of this
amount, USP’s anticipated routine return is $400 mil-
lion and FS’s anticipated routine return is $600 mil-
lion. After deducting the routine return, USP’s total
anticipated residual operating profit is $8 billion ($8.4
billion - $0.4 billion) and FS’s total anticipated resid-
ual operating profit equals $12 billion ($12.6 billion
- $0.6 billion).
(iv) After analysis, USP and FS determine that the
relative values of the nanomotor and nanosensor tech-
nologies are most reliably measured by their respec-
tive capitalized costs of development. Some of the
factors considered in this analysis include the simi-
lar nature and success, and the relatively contempo-
raneous timing, of the nanoengineering research done
to develop both the nanomoter and nanosensor tech-
nologies and the lack of external market benchmarks.
The capitalized costs of the nanomotor and nonsen-
sor technologies are $3 billion and $5 billion, respec-
tively.
(v) Under the residual profit split method, in each
taxable year USP and FS will allocate the operating
income they each separatelyreport in their territory
(territorial operating income) between their routine
contributions, their cost contribution share and their
nonroutine contributions, in this case the nanomotor
and nanosensor technologies.
(vi) In step one of the residual profit split, USP
and FS each allocate an amount of income that is sub-
tracted from their actual territorial operating income
for the taxable year to provide a market return for
their actual routine contributions in that year.
(vii) In step two, a portion of residual territorial
operating profit or loss after accounting for the allo-
cation of income to routine contributions in step one,
will be allocated by USP and FS to their cost con-
tribution shares. The percentage allocable to the cost
contribution share in this case is equal to the each par-
ticipant’s share of total anticipated IDCs divided by
the difference between its total anticipated operating
profits in its territory and the total anticipated routine
return in its territory. It follows that the cost contri-
bution shares of USP and FS are as follows: USP =
50% ($4 billion / $8 billion) and FS = 50% ($6 billion
/ $12 billion).
(viii) In step three, USP and FS each allocate
a portion of their residual territorial operating in-
come remaining after application of steps one and
two between their respective nonroutine contribu-
tions. USP and FS have estimated relative values for
USP’s nanomotor technology at $3 billion and FS’s
nanosensor technology at $5 billion. The percentage
of each participant’s residual territorial operating in-
come that is allocated to the nanomotor technology is
therefore 37.5% ($3 billion/($3 billion + $5 billion))
and the percentage allocated to the nanosensor tech-
nology is 62.5% ($5 billion/($3 billion + $5 billion)).
(ix) USP will owe a PCT Payment to FS equal
to the amount of its territorial operating profit or loss
that is allocated in step three to FS’s nanosensor tech-
nology and FS will owe a PCT Payment to USP equal
to the amount of its territorial operating profit or loss
that is allocated in step three to USP’s nanomotor
technology. The PCT Payments owed each year by
USP and FS, respectively, will be netted against each
other, so that only one participant will make a net PCT
Payment.
(8)Unspecified methods. Methods not
specified in paragraphs (g)(3) through (7)
of this section may be used to evaluate
whether the amount charged for a PCT is
arm’s length. Any method used under this
paragraph (g)(8) must be applied in accor-
dance with the provisions of §1.482–1 and
of paragraph (g)(2) of this section. Con-
sistent with the specified methods, an un-
specified method should take into account
the general principle that uncontrolled tax-
payers evaluate the terms of a transaction
by considering the realistic alternatives to
that transaction, and only enter into a par-
ticular transaction if none of the alterna-
tives is preferable to it. Therefore, in
establishing whether a PCT achieved an
arm’s length result, an unspecified method
should provide information on the prices
or profits that the controlled participant
could have realized bychoosing a realis-
tic alternative to the CSA. As with any
method, an unspecified method will not
be applied unless it provides the most re-
liable measure of an arm’s length result
under the principles of the best method
rule. See §1.482–1(c). In accordance with
§1.482–1(d) (Comparability), to the extent
that an unspecified method relies on inter-
nal data rather than uncontrolled compara-
bles, its reliability will be reduced. Sim-
ilarly, the reliability of a method will be
affected by the reliability of the data and
assumptions used to apply the method, in-
cluding any projections used.
(h)Coordination with the arm’s length
standard. A CSA produces results that
areconsistentwithanarm’slengthresult
within the meaning of §1.482–1(b)(1) if,
and only if, each controlled participant’s
IDC share (as determined under paragraph
(d)(4) of this section) equals its RAB share
(as required by paragraph (a)(1) of this sec-
tion), and all other requirements of this
section are satisfied.
(i)Allocations by the Commissioner in
connection with a CSA—(1)In general.
The Commissioner may make allocations
to adjust the results of a controlled transac-
tion in connection with a CSA so that the
results are consistent with an arm’s length
result, in accordance with the provisions of
this paragraph (i).
(2)CST allocations—(i)In general.
The Commissioner may make allocations
to adjust the results of a CST so that the
results are consistent with an arm’s length
result, including any allocations to make
each controlled participant’s IDC share, as
determined under paragraph (d)(4) of this
section, equal to that participant’s RAB
October 3, 20056632005–40 I.R.B.

share, as determined under paragraph
(e)(1) of this section. Such allocations
may result from, for purposes of CST de-
terminations, adjustments to —
(A) Redetermine IDCs by adding any
costs (or cost categories) that are directly
identified with, or are reasonably allocable
to, the IDA, or by removing any costs (or
cost categories) that are not IDCs;
(B) Reallocate costs between the IDA
and other business activities;
(C) Improve the reliability of the se-
lection or application of the basis used
for measuring benefits for purposes of es-
timating a controlled participant’s RAB
share;
(D) Improve the reliability of the pro-
jections used to estimate RAB shares,
including adjustments described in para-
graph (i)(2)(ii) of this section; and
(E) Allocate among the controlled par-
ticipants any unallocated interests in cost
shared intangibles.
(ii)Adjustments to improve the relia-
bility of projections used to estimate RAB
shares—(A)Unreliable projections.A
significant divergence between projected
benefit shares and benefit shares adjusted
to take into account any available actual
benefits to date (adjusted benefit shares)
may indicate that the projections were not
reliable for purposes of estimating RAB
shares. In such a case, the Commissioner
may use adjusted benefit shares as the most
reliable measure of RAB shares and ad-
just IDC shares accordingly. The projected
benefit shares will not be considered unre-
liable, as applied in a given taxable year,
based on a divergence from adjusted bene-
fit shares for every controlled participant
that is less than or equal to 20% of the
participant’s projected benefits share. Fur-
ther, the Commissioner will not make an
allocation based on such divergence if the
difference is due to an extraordinary event,
beyond the control of the controlled par-
ticipants, which could not reasonably have
been anticipated at the time that costs were
shared. The Commissioner generally may
adjust projections of benefits used to cal-
culate benefit shares in accordance with
the provisions of §1.482–1. In particu-
lar, if benefits are projected over a pe-
riod of years, and the projections for ini-
tial years of the period prove to be unre-
liable, this may indicate that the projec-
tions for the remaining years of the pe-
riod are also unreliable and thus should
be adjusted. For purposes of this para-
graph, all controlled participants that are
not U.S. persons are treated as a single
controlled participant. Therefore, an ad-
justment based on an unreliable projec-
tion of RAB shares will be made to the
IDC shares of foreign controlled partici-
pants only if there is a matching adjust-
ment to the IDC shares of controlled par-
ticipants that are U.S. persons. Nothing
in this paragraph (i)(2)(ii)(A) prevents the
Commissioner from making an allocation
if taxpayer did not use the most reliable
basis for measuring anticipated benefits.
For example, if the taxpayer measures its
anticipated benefits based on units sold,
and the Commissioner determines that an-
other basis is more reliable for measuring
anticipated benefits, then the fact that ac-
tual units sold were within 20% of the pro-
jected unit sales will not preclude an allo-
cation under this section.
(B)Foreign-to-foreign adjustments.
Adjustments to IDC shares based on an
unreliable projection also may be made
solely among foreign controlled partici-
pants if the variation between actual and
projected benefits has the effect of sub-
stantially reducing U.S. tax.
(C)Correlative adjustments to PCTs.
Correlative adjustments will be made to
any PCT Payments of a fixed amount that
were determined based on RAB shares
which are subsequently adjusted on a find-
ing that they were based on unreliable
projections. No correlative adjustments
will be made to contingent PCT Payments
regardless of whether RAB shares were
used as a parameter in the valuation of
those payments.
(D)Examples. The following examples
illustrate the principles of this paragraph
(i)(2)(ii):
Example 1. U.S. Parent (USP) and Foreign Sub-
sidiary (FS) enter into a CSA to develop new food
products, dividing costs on the basis of projected
sales two years in the future. In Year 1, USP and
FS project that their sales in Year 3 will be equal,
and they divide costs accordingly. In Year 3, the
Commissioner examines the controlled participants’
method for dividing costs. USP and FS actually ac-
counted for 42% and 58% of total sales, respectively.
The Commissioner agrees that sales two years in the
future provide a reliable basis for estimating benefit
shares. Because the differences between USP’s and
FS’s adjusted and projected benefit shares are less
than 20% of their projected benefit shares, the pro-
jection of future benefits for Year 3 is reliable.
Example 2. The facts are the same as inExam-
ple 1, except that in Year 3 USP and FS actually
accounted for 35% and 65% of total sales, respec-
tively. The divergence between USP’s projected and
adjusted benefit shares is greater than 20% of USP’s
projected benefit share and is not due to an extra-
ordinary event beyond the control of the controlled
participants. The Commissioner concludes that the
projected benefit shares were unreliable, and uses ad-
justed benefit shares as the basis for an adjustment to
the cost shares borne by USP and FS.
Example 3. U.S.Parent(USP),aU.S.corpora-
tion, and its foreign subsidiary (FS) enter a CSA in
Year 1. They project that they will begin to receive
benefits from covered intangibles in Years 4 through
6, and that USP will receive 60% of total benefits and
FS 40% of total benefits. In Years 4 through 6, USP
and FS actually receive 50% each of the total bene-
fits. In evaluating the reliability of the controlled par-
ticipants’ projections, the Commissioner compares
the adjusted benefit shares to the projected benefit
shares. Although USP’s adjusted benefit share (50%)
is within 20% of its projected benefit share (60%),
FS’s adjusted benefit share (50%) is not within 20%
of its projected benefit share (40%). Based on this
discrepancy, the Commissioner may conclude that the
controlled participants’ projections were not reliable
and may use adjusted benefit shares as the basis for
an adjustment to the cost shares borne by USP and
FS.
Example 4. Three controlled taxpayers, USP, FS1
and FS2 enter into a CSA. FS1 and FS2 are foreign.
USP is a United States corporation that controls all
the stock of FS1 and FS2. The controlled partici-
pants project that they will share the total benefits of
the covered intangibles in the following percentages:
USP 50%; FS1 30%; and FS2 20%. Adjusted bene-
fit shares are as follows: USP 45%; FS1 25%; and
FS2 30%. In evaluating the reliability of the con-
trolled participants’ projections, the Commissioner
compares these adjusted benefit shares to the pro-
jected benefit shares. For this purpose, FS1 and FS2
are treated as a single controlled participant. The ad-
justed benefit share received by USP (45%) is within
20% of its projected benefit share (50%). In addition,
the non-US controlled participants’ adjusted benefit
share (55%) is also within 20% of their projected
benefit share (50%). Therefore, the Commissioner
concludes that the controlled participants’ projections
of future benefits were reliable, despite the fact that
FS2’s adjusted benefit share (30%) is not within 20%
of its projected benefit share (20%).
Example 5. ThefactsarethesameasinExam-
ple 4. In addition, the Commissioner determines that
FS2 has significant operating losses and has no earn-
ings and profits, and that FS1 is profitable and has
earnings and profits. Based on all the evidence, the
Commissioner concludes that the controlled partici-
pants arranged that FS1 would bear a larger cost share
than appropriate in order to reduce FS1’s earnings
and profits and thereby reduce inclusions USP oth-
erwise would be deemed to have on account of FS1
under subpart F. Pursuant to paragraph (i)(2)(ii)(B) of
this section, the Commissioner may make an adjust-
ment solely to the cost shares borne by FS1 and FS2
because FS2’s projection of future benefits was un-
reliable and the variation between adjusted and pro-
jected benefits had the effect of substantially reducing
USP’s U.S. income tax liability (on account of FS1
subpart F income).
Example 6. (i)(A) Foreign Parent (FP) and U.S.
Subsidiary (USS) enter into a CSA in 1996 to de-
2005–40 I.R.B.664October 3, 2005

velop a new treatment for baldness. USS’s interest in
any treatment developed is the right to produce and
sell the treatment in the U.S. market while FP retains
rights to produce and sell the treatment in the rest of
the world. USS and FP measure their anticipated ben-
efits from the cost sharing arrangement based on their
respective projected future sales of the baldness treat-
ment. The following sales projections are used:

(B) In Year 1, the first year of sales, USS is pro-
jected to have lower sales than FP due to lags in U.S.
regulatory approval for the baldness treatment. In
each subsequent year USS and FP are projected to
have equal sales. Sales are projected to build over
the first three years of the period, level off for several
years, and then decline over the final years of the pe-
riod as new and improved baldness treatments reach
the market.
(ii) To account for USS’s lag in sales in the Year 1,
the present discounted value of sales over the period
is used as the basis for measuring benefits. Based on
the risk associated with this venture, a discount rate of
10 percent is selected. The present discounted value
of projected sales is determined to be approximately
$154.4 million for USS and $158.9 million for FP. On
this basis USS and FP are projected to obtain approx-
imately 49.3% and 50.7% ofthe benefit, respectively,
and the costs of developing the baldness treatment are
shared accordingly.
(iii) (A) In Year 6 the Commissioner examines the
cost sharing arrangement. USS and FP have obtained
the following sales results through the Year 5:

(B) USS’s sales initially grew more slowly than
projected while FP’s sales grew more quickly. In
each of the first three years of the period the share
of total sales of at least one of the parties diverged
by over 20% from its projected share of sales. How-
ever, by Year 5 both parties’ sales had leveled off at
approximately their projected values. Taking into ac-
count this leveling off of sales and all the facts and
circumstances, the Commissioner determines that it
is appropriate to use the original projections for the
remaining years of sales. Combining the actual re-
sults through Year 5 with the projections for subse-
quent years, and using a discount rate of 10%, the
present discounted value of sales is approximately
$141.6 million for USS and $187.3 million for FP.
This result implies that USS and FP obtain approxi-
mately 43.1% and 56.9%, respectively, of the antici-
pated benefits from the baldness treatment. Because
these adjusted benefit shares are within 20% of the
benefit shares calculated based on the original sales
projections, the Commissioner determines that, based
on the difference between adjusted and projected ben-
efit shares, the original projections were not unreli-
able. No adjustment is made based on the difference
between adjusted and projected benefit shares.
Example 7. (i) The facts are the same as inExam-
ple 6, except that the actual sales results through Year
5 are as follows:

(ii) Based on the discrepancy between the projec-
tions and the actual results and on consideration of all
the facts, the Commissioner determines that for the
remaining years the following sales projections are
more reliable than the original projections:

(iii) Combining the actual results through Year 5
with the projections for subsequent years, and using
a discount rate of 10%, the present discounted value
of sales is approximately $131.2 million for USS and
$229.4 million for FP. This result implies that USS
and FP obtain approximately 35.4% and 63.6%, re-
spectively, of the anticipated benefits from the bald-
ness treatment. These adjusted benefit shares diverge
by greater than 20% from the benefit shares calcu-
lated based on the original sales projections, and the
Commissioner determines that, based on the differ-
ence between adjusted and projected benefit shares,
the original projections were unreliable. The Com-
missioner adjusts cost shares for each of the taxable
years under examination to conform them to the re-
calculated shares of anticipated benefits.
(iii)Timing of CST allocations.Ifthe
Commissionermakesanallocationtoad-
just the results of a CST, the allocation
must be reflected for tax purposes in the
year in which the IDCs were incurred.
When a cost sharing payment is owed by
one controlled participant to another con-
trolled participant, the Commissioner may
make appropriate allocations to reflect an
arm’s length rate of interest for the time
value of money, consistent with the provi-
sions of §1.482–2(a) (Loans or advances).
(3)PCT allocations.TheCommis-
sioner may make allocations to adjust
the results of a PCT so that the results
are consistent with an arm’s length re-
sult in accordance with the provisions of
the applicable sections of the section 482
regulations, as determined pursuant to
paragraph (a)(2) of this section.
(4)Allocations regarding changes in
participation under a CSA.TheCommis-
sioner may make allocations to adjust the
results of any controlled transaction de-
scribed in paragraph (f) of this section, if
the controlled participants do not reflect
arm’s length results in relation to any such
transaction.
(5)Allocations when CSTs are consis-
tently and materially disproportionate to
RAB shares. If a controlled participant
bears IDC shares that are consistently
and materially greater or lesser than its
RAB share, then the Commissioner may
conclude that the economic substance of
the arrangement between the controlled
participants is inconsistent with the terms
of the CSA. In such a case, the Com-
missioner may disregard such terms and
impute an agreement that is consistent
with the controlled participants’ course
of conduct, under which a controlled par-
ticipant that bore a disproportionately
greater IDC share received additional
interests in the cost shared intangibles.
See §1.482–1(d)(3)(ii)(B) (Identifying
contractual terms) and §1.482–4(f)(3)(ii)
(Identification of owner). Such additional
interests will consist of partial undivided
interests in another controlled participant’s
territory. Accordingly, that controlled par-
ticipant must receive arm’s length con-
sideration from any controlled participant
whoseIDCshareislessthanitsRAB
share over time, under the provisions of
§§1.482–1 and 1.482–4 through 1.482–6.
(6)Periodic adjustments—(i)In gen-
eral. Subject to the exceptions in para-
graph (i)(6)(vi) of this section, the Com-
missioner may make periodic adjustments
with respect to all PCT Payments for an
open taxable year (the Adjustment Year),
and for all subsequent taxable years for
the duration of the CSA Activity, if the
Commissioner determines that, for a par-
ticular PCT (the Trigger PCT), a particular
October 3, 20056652005–40 I.R.B.

controlled participant that owes or owed
a PCT Payment relating to that PCT (the
PCT Payor) has realized an Actually Ex-
perienced Return Ratio (AERR) that is
outside the Periodic Return Ratio Range
(PRRR). The satisfaction of the condi-
tion stated in the preceding sentence is
referred to as a Periodic Trigger. See para-
graph (i)(6)(ii) through (vi) of this section
regarding the PRRR, the AERR, and peri-
odic adjustments. In determining whether
to make such adjustments, the Commis-
sioner may consider whether the outcome
as adjusted more reliably reflects an arm’s
length result under all the relevant facts
and circumstances, including any informa-
tion known as of the Determination Date.
The Determination Date is the date of the
relevant determination by the Commis-
sioner. The failure of the Commissioner to
determine for an earlier taxable year that
a PCT Payment was not arm’s length will
not preclude the Commissioner from mak-
ing a periodic adjustment for a subsequent
year. A periodic adjustment under this
paragraph may be made without regard
to whether the taxable year of the Trigger
PCT or any other PCT remains open for
statute of limitations purposes.
(ii)PRRR.Exceptasprovidedinthe
next sentence, the PRRR will consist of re-
turn ratios that are not less than
1
/2nor more
than 2. Alternatively, if the controlled par-
ticipants have not substantially complied
with the documentation requirements ref-
erenced in paragraph (k) of this section,
as modified, if applicable, by paragraph
(m)(3) of this section, the PRRR will con-
sist of the return ratios that are not less than
.67 nor more than 1.5.
(iii)AERR.(A)In general.TheAERR
is the Present Value of Total Profits
(PVTP) divided by the Present Value
of Investment (PVI). In computing PVTP
and PVI, present values are computed us-
ing the Applicable Discount Rate (ADR),
and all information available as of the
Determination Date is taken into account.
(B)PVTP. The PVTP is the present
value, as of the earliest date that any IDC
described in paragraph (d)(1) of this sec-
tion occurred (the CSA Start Date), of the
PCT Payor’s actually experienced territo-
rial operating profits, as defined in para-
graph (j)(1)(vi) of this section, from the
CSA Start Date through the end of the Ad-
justment Year.
(C)PVI. The PVI is the present value,
as of the CSA Start Date, of the PCT
Payor’s investment associated with the
CSA Activity, defined as the sum of its
cost contributions and its PCT Payments,
from the CSA Start Date through the end
of the Adjustment Year. For purposes of
computing the PVI, PCT Payments means
all PCT Payments due from a PCT Payor
before netting against PCT Payments due
from other controlled participants.
(iv)ADR—(A)In general. Except as
provided in paragraph (i)(6)(iv)(B) of this
section, the ADR is the discount rate pur-
suant to paragraph (g)(2)(vi) of this sec-
tion, subject to such adjustments as the
Commissioner determines appropriate.
(B)Publicly traded companies.Ifthe
PCT Payor meets the conditions of para-
graph (i)(6)(iv)(C) of this section, the ADR
is the PCT Payor WACC as of the date of
thetriggerPCT.However,iftheCommis-
sioner determines, or the controlled partic-
ipants establish to the Commissioner’s sat-
isfaction, that a discount rate other than the
PCT Payor WACC better reflects the de-
gree of risk of the CSA Activity as of such
date, the ADR is such other discount rate.
(C)Publicly traded.APCTPayor
meets the conditions of this paragraph
(i)(6)(iv)(C) if —
(1) Stock of the PCT Payor is publicly
traded; or
(2) Stock of the PCT Payor is not pub-
licly traded, provided —
(i) The PCT Payor is included in a group
of companies for which consolidated fi-
nancial statements are prepared; and
(ii) A publicly traded company in such
group owns, directly or indirectly, stock
in PCT Payor. Stock of a company is
publicly traded within the meaning of this
paragraph (i)(6)(iv)(C) if such stock is
regularly traded on an established United
States securities market and the company
issues financial statements prepared in
accordance with United States generally
accepted accounting principles for the tax-
able year.
(D)PCT Payor WACC.ThePCTPayor
WACC is the WACC of the PCT Payor or
the publicly traded company described in
paragraph (i)(6)(iv)(C)(2) of this section,
as the case may be.
(E)Generally accepted accounting
principles. For purposes of paragraph
(i)(6)(iv)(C) of this section, a financial
statement prepared in accordance with
a comprehensive body of generally ac-
cepted accounting principles other than
United States generally accepted account-
ing principles is considered to be prepared
in accordance with United States generally
accepted accounting principles provided
that the amounts of debt, equity and in-
terest expense are reflected in the recon-
ciliation between such other accounting
principles and United States generally ac-
cepted accounting principles required to
be incorporated into the financial state-
ment by the securities laws governing
companies whose stock is regularly traded
on United States securities markets.
(v)Determination of periodic adjust-
ments. In the event of a Periodic Trigger,
subject to paragraph (i)(6)(vi) of this
section, the Commissioner may make pe-
riodic adjustments with respect to all PCT
Payments between all PCT Payors and
PCT Payees for the Adjustment Year and
all subsequent years for the duration of
the CSA Activity pursuant to the residual
profit split method as provided in para-
graph (g)(7) of this section, subject to the
further modifications in this paragraph
(i)(6)(v).
(A)IftheAERRislessthanthe
PRRR, then the cost contribution share
of residual profit or loss under paragraph
(g)(7)(iii)(C)(2) of this section is deter-
mined as follows:
(1) The relevant date specified in that
paragraph is the CSA Start Date. How-
ever, the effect of using such relevant date
is modified as specified in paragraphs
(i)(6)(v)(A)(2) and (i)(6)(v)(A)(3)ofthis
section.
(2) The discount rate to be used in para-
graph (g)(7)(iii)(C)(2) of this section is de-
termined as of the relevant date, but taking
into account any data relevant to such de-
termination that may become available up
through the Determination Date.
(3) The present values of the
summations described in paragraph
(g)(7)(iii)(C)(2)ofthissectionarede-
termined by substituting actual results up
through the Determination Date, and fu-
ture results anticipated on that date, for the
results anticipated on the relevant date. It
is possible that, because of these substitu-
tions, the resulting fraction determined in
that paragraph will be greater than one.
(B) If the AERR is greater than the
PRRR, then the cost contribution share
of residual profit or loss under paragraph
2005–40 I.R.B.666October 3, 2005

(g)(7)(iii)(C)(2) of this section is deter-
mined as follows:
(1) The relevant date specified in that
paragraph is the first day of the Adjust-
ment Year. However, the effect of using
such relevant date is modified as spec-
ified in paragraphs (i)(6)(v)(B)(2)and
(i)(6)(v)(B)(3) of this section.
(2) The discount rate to be used in para-
graph (g)(7)(iii)(C)(2) of this section is de-
termined as of the relevant date, but taking
into account any data relevant to such de-
termination that may become available up
through the Determination Date.
(3) In computing the fraction described
in paragraph (g)(7)(iii)(C)(2)ofthissec-
tion, the summation period described in
that paragraph is modified to start on the
first day of the Adjustment Year; thus, the
summations described in that paragraph
that are used to determine that fraction will
not include any items relating to periods
before the first day of the Adjustment Year.
(C) The relative value of non-
routine contributions in paragraph
(g)(7)(iii)(C)(3) of this section are de-
termined as described in that paragraph,
but taking into account any data relevant
to such determination that may become
available up through the Determination
Date.
(D) For these purposes, the residual
profit split method may be used even
where only one controlled participant
makes significant nonroutine contribu-
tions to the CSA Activity. If only one
controlled participant provides all the ex-
ternal contributions and other nonroutine
contributions, then the third step residual
profit or loss belongs entirely to such con-
trolled participant.
(vi)Exceptions to periodic adjustments
—(A)Transactions involving the same ex-
ternal contribution as in the PCT.If—
(1) The same external contribution is
furnished to an uncontrolled taxpayer un-
der substantially the same circumstances
as those of the relevant RT (as defined in
paragraph (b)(3)(iv) of this section) and
with a similar form of payment as the PCT;
(2)Thistransactionservesasthebasis
for the application of the comparable un-
controlled transaction method described
in §1.482–4(c), or the arm’s length charge
described in §1.482–2(b)(3)(first sen-
tence) based on a comparable uncontrolled
transaction, in the first year in which sub-
stantial PCT Payments relating to this PCT
were required to be paid; and
(3) The amount of those PCT Payments
in that year was arm’s length; then no pe-
riodic adjustment that uses that PCT as
theTriggerPCTwillbemadeunderpara-
graphs (i)(6)(i) and (i)(6)(v) of this section.
(B)Results not reasonably anticipated.
If the controlled participants establish to
the satisfaction of the Commissioner that
the differential between the AERR and the
nearest bound of the PRRR is due to extra-
ordinary events beyond its control and that
could not reasonably have been anticipated
at the time of the Trigger PCT, then no pe-
riodic adjustment will be made under para-
graphs (i)(6)(i) and (i)(6)(v) of this section.
(C)Reduced AERR does not cause Peri-
odic Trigger. If the controlled participants
establish to the satisfaction of the Commis-
sioner that the Periodic Trigger would not
have occurred had the PCT Payor’s oper-
ating profits used to calculate its PVTP ex-
cluded those operating profits attributable
to the PCT Payor’s routine contributions
to its exploitation of cost shared intangi-
bles, and nonroutine contributions to the
CSA Activity, then no periodic adjustment
will be made under paragraphs (i)(6)(i) and
(i)(6)(v) of this section.
(D)Increased AERR does not cause
Periodic Trigger—(1)Ifthecontrolled
participants establish to the satisfaction
of the Commissioner that the Periodic
Trigger would not have occurred had the
operating profits of the PCT Payor used
to calculate its PVTP included its reason-
ably anticipated operating profits after the
Adjustment Year from the CSA Activity,
including from routine contributions to
that activity, and had the cost contribu-
tions and PCT Payments of the PCT Payor
used to calculate its PVI included its rea-
sonably anticipated cost contributions and
PCT Payments after the Adjustment Year,
then no periodic adjustment will be made
under paragraphs (i)(6)(i) and (i)(6)(v)
of this section. The reasonably antici-
pated amounts in the previous sentence
are determined based on all information
available as of the Determination Date.
(2) For purposes of this paragraph
(i)(6)(vi)(D) of this section, the controlled
participants may, if they wish, assume
that the average yearly operating profits
for all taxable years prior to and includ-
ing the Adjustment Year, in which there
has been substantial exploitation of cost
shared intangibles resulting from the CSA
(exploitation years), will continue to be
earned in each year over a period of years
equal to 15 minus the number of ex-
ploitation years prior to and including the
Determination Date.
(E)10-year period.IftheAERRdeter-
mined is within the PRRR for each year of
the 10-year period beginning with the first
taxable year in which there is substantial
exploitation of cost shared intangibles re-
sulting from the CSA, then no periodic ad-
justment in a subsequent year will be made
under paragraphs (i)(6)(i) and (i)(6)(v) of
this section.
(F)5-year period. For any year of the
5-year period beginning with the first tax-
able year in which there is substantial ex-
ploitation of cost shared intangibles result-
ing from the CSA, no Periodic Trigger will
be considered to occur as a result of a de-
termination that the AERR falls below the
lower bound of the PRRR.
(vii)Examples. The following exam-
ples illustrates the principles of this para-
graph (i)(6):
Example 1. (i) At the beginning of Year 1, USP,
a publicly traded U.S. company, and FS, its wholly-
owned foreign subsidiary, enter into a CSA to develop
new technology for wireless cell phones. As part of a
PCT, USP furnishes an external contribution, the RT
Rights for an in-process technology that when devel-
oped will improve the clarity of cell to cell calls, for
which compensation is due from FS. FS furnishes no
external contributions to the CSA. The weighted av-
erage cost of capital of thecontrolled group that in-
cludes USP and FS in Year 1 is 15%. In Year 10,
the Commissioner audits Years 1 through 8 of the
CSA to determine whether or not any periodic adjust-
ments should be made. USP and FS have substan-
tially complied with the documentation requirements
of this section.
(ii) FS derives the following actual cash flow
from its participation in the CSA. The cash flows
include the lump sum PCT payment of $100 million
made by FS to USP. The derivation of such PCT Pay-
ment was based on financial projections undertaken
in Year 1 (not shown). (All amounts in this table and
the tables that follow are in millions.)

(iii) Because USP is publicly traded in the United
States and is a member of the controlled group to
which the PCT Payor, FS, belongs, for purposes of
calculating the AERR for FS, the present values of
its PVTP and PVI are determined using an ADR of
15%, the weighted average cost of capital of the con-
trolled group. At a 15% discount rate, the PVTP, cal-
culated in Year 8 as of Year 1, and based on actual
profits realized by FS through Year 7 from exploiting
the new wireless cell phone technology developed by
the CSA, is $733 million. The PVI, based on FS’s
IDCs and its compensation expenditures pursuant to
the PCT, is $192 million. The AERR for FS is equal
to its PVTP divided by its PVI, $733 million/$192
million, or 3.8. There is a Periodic Trigger because
FS’s AERR of 3.8 falls outside the PRRR of
1
/2to 2,
the applicable PRRR for controlled participants com-
plying with the documentation requirements of this
section.
(iv) At the time of the Determination Date, it is
determined that the first Adjustment Year in which
a Periodic Trigger occurred was Year 6, when the
AERR of FS was determined to be 3.0. It is also deter-
mined that none of the exceptions to periodic adjust-
ments described in paragraph (i)(6)(vi) of this section
applies. It follows that the arm’s length PCT Pay-
ments made by FS from Year 6 forward shall be deter-
mined each taxable year using the residual profit split
method described in paragraph (g)(7) of this section
as modified by paragraph (i)(6)(v) of this section. Pe-
riodic adjustments will be made to the extent the PCT
Payments actually made by FS differ from the PCT
Payment calculation under the residual profit split.
(v) Actual and projected IDCs, territorial operat-
ing profits and returns to routine contributions for the
remainder of the exploitation of the cost shared intan-
gibles, determined as of the beginning of Year 6 are
as follows:

a portion of its actual territorial operating income for
the taxable year to provide a market return for its ac-
tual routine contributions in that year. As a result of
a transfer pricing analysis, the Commissioner deter-
mines that the return to FS’s routine activities, based
on the return for comparable routine functions under-
taken by comparable unrelated companies, is 10% of
non-IDC costs. The allocations of actual territorial
profits in Years 6 through 8 are as follows:
YearTerritorial operating
profits
Return to routine
contributions
Residual profits after
step 1
644468376
7432
75357
841682334
(vii) Under step two, a portion of the residual ter-
ritorial operating profit or loss after the allocation
of profit to routine contributions in step one will be
allocated by FS to its cost contribution share. The
percentage allocable to the cost contribution share is
equal to FS’s share of the total anticipated IDCs di-
vided by its total anticipated territorial operating prof-
its reduced by total expected return to its routine con-
tributions to the exploitation of the cost shared tech-

nology in its territory. All amounts are determined as
present values as of the first day of Year 6, using an
appropriate discount rate on that date, and do not in-
clude any amounts relating to periods before the first
day of Year 6. Following these rules, it is determined
that the present value of FS’s share of the total an-
ticipated IDCs after the first day of Year 6 is $116
million and its total anticipated territorial operating
profits reduced by the return to its routine contribu-
tions is $1,340 million. It follows that the percentage
of residual territorial operating profit or loss allocated
to FS’s cost contribution share is 8.6% ($116/$1,340).
The allocation of actual residual profits after Step 1
in Years 6 through 8 is as follows:

(viii) In step three, because USP provided the
only nonroutine contributions to the CSA Activity,
100% of FS’s residual operating income after steps
one and two is allocated to USP’s external contribu-
tions and therefore represents the amount of the PCT
Payment due from FS to USP for the particular tax-
able year. Also because USP provided the only non-
routine contributions to the CSA Activity, none of its
residual territorial operating profit or loss is attribut-
able to FS, therefore no offsetting PCT Payment is
due from USP to FS. The PCT Payments due and ad-
justmentsmadeinYears6through8areasfollows:

Example 2. The facts are the same asExample 1
paragraphs (i) through (iii). At the time of the De-
ter
mination Date, it is determined that the first Ad-
justment Year in which a Periodic Trigger occurred
was Year 6, when the AERR of FS was determined
to b
e 3.0. Upon further investigation as to what may
have caused the high return in FS’s market, the Com-
missioner learns that, in Year 4, significant health
ris
ks were linked to the use of wireless cell phones of
USP’s leading competitors. No such health risk was
linked to the cell phones developed by USP and FS
un
der the CSA. This resulted in a significant increase
in USP’s and FS’s market share for cellular phones.
Further analysis determines that it was this unfore-
se
en occurrence that was primarily responsible for the
AERR trigger. Based on paragraph (i)(6)(vi)(B) of
this section, the Commissioner concludes that no ad-
j
ustments are warranted, as FS simply has earned the
premium return that any such investor would earn un-
der the circumstances.
(j)Definitions and special rules—(1)
Definitions. For purposes of this section:
(i)Controlled participantmeans a
controlled taxpayer, as defined under
§1.482–1(i)(5), that is a party to the con-
tractual agreement that underlies the CSA,
and that reasonably anticipates that it will
derive benefits, as defined in paragraph
(j)(1)(iv) of this section, from exploiting
one or more cost shared intangibles.
(ii)Cost shared intangiblemeans
any intangible, within the meaning of
§1.482–4(b), developed or to be devel-
oped as a result of the IDA, as described in
paragraph (d)(1) of this section, including
any portion of such intangible that reflects
an external contribution, as described in
paragraph (b)(3)(ii) of this section.
(iii) Aninterest in an intangiblein-
cludes any commercially transferable in-
terest, the benefits of which are susceptible
of valuation.
(iv)Benefitsmean the sum of additional
revenue generated, plus cost savings, mi-
nus any cost increases from exploiting cost
shared intangibles.
(v) A controlled participant’sreason-
ably anticipated benefitsmean the aggre-
gate benefits that reasonably may be antic-
ipated to be derived from exploiting cost
shared intangibles.
(vi)Territorial operating profit or loss
means the operating profit or loss as sep-
arately earned by each controlled partici-
pant in its geographic territory, described
in paragraph (b)(4) of this section, from
the CSA activity, determined before any
expense (including amortization) on ac-
count of IDCs, routine external contribu-
tions, and nonroutine contributions.
(vii) TheCSA Activityis the activity
of developing and exploiting cost shared
intangibles.
(viii)Examples. The following exam-
ples illustrate the principles of this para-
graph (j)(1):
Example 1.Controlled participant.ForeignPar-
e
nt (FP) is a foreign corporation engaged in the ex-
traction of a natural resource. FP has a U.S. sub-
sidiary (USS) to which FP sells supplies of this re-
source for sale in the United States. FP enters into
a CSA with USS to develop a new machine to ex-
tra
ct the natural resource. The machine uses a new
extraction process that will be patented in the United
States and in other countries. The CSA provides that
USS
will receive the rights to exploit the machine in
the extraction of the natural resource in the United
States, and FP will receive the rights in the rest of the
wor
ld. This resource does not, however, exist in the
United States. Despite the fact that USS has received
the right to exploit this process in the United States,
US
S is not a controlled participant because it will not
derive a benefit from exploiting the intangible devel-
oped under the CSA.
Ex
ample 2.Controlled participants.(i)U.S.Par-
ent (USP), one foreign subsidiary (FS), and a second
foreign subsidiary constituting the group’s research
a
rm (R+D) enter into a CSA to develop manufactur-
ing intangibles for a new product line A. USP and FS
are assigned the exclusive rights to exploit the intan-
g
ibles respectively in the United States and the rest
of the world, where each presently manufactures and
sells various existing product lines. R+D is not as-
s
igned any rights to exploit the intangibles. R+D’s
activity consists solely in carrying out research for the
group. It is reliably projected that the RAB shares of
USP and FS will be 66 2/3% and 33 1/3%, respec-
tively, and the parties’ agreement provides that USP
and FS will reimburse 66 2/3% and 33 1/3%, respec-
tively, of the IDCs incurred by R+D with respect to
the new intangible.
(ii) R+D does not qualify as a controlled partici-
pant within the meaning of paragraph (j)(1)(i) of this
section, because it will not derive any benefits from
exploiting cost shared intangibles. Therefore, R+D
is treated as a service provider for purposes of this
section and must receive arm’s length consideration
for the assistance it is deemed to provide to USP and
FS, under the rules of paragraph (a)(3) of this section
and §1.482–4(f)(3)(iii). Such consideration must be
October 3, 20056692005–40 I.R.B.

treated as IDCs incurred by USP and FS in proportion
to their RAB shares (i.e., 66 2/3% and 33 1/3%, re-
spectively). R+D will not be considered to bear any
share of the IDCs under the arrangement.
Example 3.Cost shared intangible. U.S. Parent
(USP) has developed and currently exploits an anti-
histamine, XY, which is manufactured in tablet form.
USP enters into a CSA with its wholly-owned foreign
subsidiary (FS) to develop XYZ, a new improved ver-
sion of XY that will be manufactured as a nasal spray.
XYZ is a cost shared intangible under the CSA.
Example 4.Cost shared intangible. The facts
are the same as inExample 3, except that instead of
developing XYZ, the controlled participants develop
ABC, a cure for the common cold. ABC is a cost
shared intangible under the CSA.
Example 5.Reasonably anticipated benefits.
Controlled parties A and B enter into a cost sharing
arrangement to develop product and process intan-
gibles for an already existing Product P. Without
such intangibles, A and B would each reasonably
anticipate revenue, in present value terms, of $100M
from sales of Product P until it became obsolete.
With the intangibles, A and B each reasonably antic-
ipate selling the same number of units each year, but
reasonably anticipate that the price will be higher.
Because the particular product intangible is more
highly regarded in A’s market, A reasonably antici-
pates an increase of $20M in present value revenue
from the product intangible, while B reasonably
anticipates only an increase of $10M. Further, A
and B each reasonably anticipate spending an extra
$5M present value in production costs to include the
feature embodying the product intangible. Finally, A
and B each reasonably anticipate saving $2M present
value in production costs by using the process in-
tangible. A and B reasonably anticipate no other
economic effects from exploiting the cost shared
intangibles. A’s reasonably anticipated benefits from
exploiting the cost shared intangibles equal its rea-
sonably anticipated increase in revenue ($20M) plus
its reasonably anticipatedcost savings ($2M) minus
its reasonably anticipatedincreased costs ($5M),
which equals $17M. Similarly, B’s reasonably an-
ticipated benefits from exploiting the cost shared
intangibles equal its reasonably anticipated increase
in revenue ($10M) plus its reasonably anticipated
cost savings ($2M) minusits reasonably anticipated
increased costs ($5M), which equals $7M. Thus A’s
reasonably anticipated benefits are $17M and B’s
reasonably anticipated benefits are $7M.
(2)Special rules—(i)Consolidated
group. For purposes of this section, all
members of the same consolidated group
shall be treated as one taxpayer. For pur-
poses of this paragraph (j)(2)(i), the term
consolidated groupmeans all members of
a group of controlled entities created or or-
ganized within a single country and sub-
jected to an income tax by such country on
the basis of their combined income.
(ii)Trade or business.Aparticipant
that is a foreign corporation or nonresi-
dent alien individual will not be treated
as engaged in a trade or business within
the United States solely by reason of its
participation in a CSA described in para-
graph (b)(1) of this section. See generally
§1.864–2(a).
(iii)Partnership. A CSA, or an arrange-
ment to which the Commissioner applies
the rules of this section, will not be treated
as a partnership to which the rules of sub-
chapter K of the Internal Revenue Code
apply. See §301.7701–1(c) of this chapter.
(3)Character—(i)In general.CST
payments generally will be considered
costs of developing intangibles of the
payor and reimbursements of the same
kind of costs of developing intangibles of
the payee. For purposes of this paragraph
(j)(3), a controlled participant’s payment
required under a CSA is deemed to be re-
duced to the extent of any payments owed
to it under the CSA from other controlled
participants. Each payment received by a
payee will be treated as comingpro rata
from payments made by all payors. Such
payments will be appliedpro rataagainst
deductions for the taxable year that the
payee is allowed in connection with the
CSA. Payments received in excess of such
deductions will be treated as in consid-
eration for use of the land and tangible
property furnished for purposes of the
CSA by the payee. For purposes of the re-
search credit determined under section 41,
cost sharing payments among controlled
participants will be treated as provided
for intra-group transactions in §1.41–6(e).
Any payment made or received by a tax-
payer pursuant to an arrangement that
the Commissioner determines not to be a
CSA will be subject to the provisions of
§§1.482–1 and 1.482–4 through 1.482–6.
Any payment that in substance constitutes
a cost sharing payment will be treated as
such for purposes of this section, regard-
less of its characterization under foreign
law.
(ii)PCT Payments.APCTPayor’s
payment required under paragraphs
(b)(1)(ii) and (b)(3) of this section is
deemed to be reduced to the extent of
any payments owed to it under such para-
graphs from other controlled participants.
Each PCT Payment received by a PCT
Payee will be treated as comingpro rata
out of payments made by all PCT Payors.
PCT Payments will be characterized con-
sistently with the designation of the type of
transaction involved in the RT pursuant to
paragraph (b)(iv) of this section. Depend-
ing on such designation, such payments
will be treated as either consideration for
a transfer of an interest in intangible prop-
erty or for services.
(iii)Examples. The following examples
illustrate this paragraph (j)(3):
Example 1. U.S. Parent (USP) and its wholly
owned Foreign Subsidiary (FS) form a CSA to de-
velop a miniature widget, the Small R. Based on RAB
shares, USP agrees to bear 40% and FS to bear 60%
of the costs incurred during the term of the agreement.
The principal IDCs are operating costs incurred by FS
in Country Z of 100X annually, and costs incurred
by USP in the United States also of 100X annually.
Of the total costs of 200X, USP’s share is 80X and
FS’s share is 120X so that FS must make a payment
to USP of 20X. The payment will be treated as a reim-
bursement of 20X of USP’s costs in the United States.
Accordingly, USP’s Form 1120 will reflect an 80X
deduction on account of activities performed in the
United States for purposes of allocation and appor-
tionment of the deduction to source. The Form 5471
for FS will reflect a 100X deduction on account of
activities performed in Country Z, and a 20X deduc-
tion on account of activities performed in the United
States.
Example 2.ThefactsarethesameasinExample
1, except that the 100X of costs borne by USP consist
of 5X of costs incurred by USP in the United States
and 95X of arm’s length rental charge, as described
in paragraph (d)(1) of this section, for the use of a
facility in the United States. The depreciation deduc-
tion attributable to the U.S. facility is 7X. The 20X
net payment by FS to USP will first be applied in re-
ductionpro rataof the 5X deduction for costs and the
7X depreciation deduction attributable to the U.S. fa-
cility. The 8X remainder will be treated as rent for
the U.S. facility.
Example 3. (i) Four members A, B, C, and D of
a controlled group form a CSA to develop the next
generation technology for their business. Based on
RAB shares, the participants agree to bear shares of
the costs incurred during the term of the agreement in
the following percentages: A 40%; B 15%; C 25%;
and D 20%. The arm’s length values of the exter-
nal contributions they respectively own are in the fol-
lowing amounts for the taxable year: A 80X; B 40X;
C 30X; and D 30X. The provisional (before offsets)
and final PCT Payments among A, B, C, and D are
shown in the table as follows:

(ii) The first row/first column shows A’s provi-
sional PCT Payment equal to the product of 100X
(sum o
f 40X, 30X, and 30X) and A’s RAB share of
40%. The second row/first column shows A’s provi-
sional PCT receipts equal to the sum of the products
of 80
X and B’s, C’s, and D’s RAB shares (15%, 25%,
and 20%, respectively). The other entries in the first
two rows of the table are similarly computed. The last
row s
hows the final PCT receipts/payments after off-
sets. Thus, for the taxable year, A and B are treated as
receiving the 8X and 13X, respectively,pro rataout
of p
ayments by C and D of 15X and 6X, respectively.
(k)
CSA contractual, documentation,
acc
ounting, and reporting requirements
—(1
)CSA contractual requirements—
(i)
In general. A CSA that is described
in
paragraph (b)(1) of this section must
be
recorded in writing in a contract that is
co
ntemporaneous with the formation (and
an
y revision) of the CSA and that includes
th
e contractual provisions described in this
pa
ragraph (k)(1).
(i
i)Contractual provisions. The written
c
ontract described in this paragraph (k)(1)
m
ust include provisions that —
(
A) List the controlled participants and
a
ny other members of the controlled group
t
hat are reasonably anticipated to benefit
f
rom the use of the cost shared intangibles,
i
ncluding the address of each domestic en-
t
ity and the country of organization of each
foreign entity;
(
B) Describe the scope of the IDA to
be undertaken, including each cost shared
intangible or class of cost shared intangi-
bles that the controlled participants intend
to develop under the CSA;
(C) Specify the functions and risks that
each controlled participant will undertake
in connection with the CSA;
(D) Divide among the controlled par-
ticipants all interests in cost shared in-
tangibles and specify each controlled
participant’s territorial interest in the cost
shared intangibles, as described in para-
graph (b)(4) of this section, that it will
own and exploit without any further obli-
gation to compensate any other controlled
participant for such interest;
(E) Provide a method to calculate the
controlled participants’ RAB shares, based
on factors that can reasonably be expected
to reflect the participants’ shares of antici-
pated benefits, and require that such RAB
shares must be updated, as described in
paragraph (e)(1) of this section (see also
paragraph (k)(2)(ii)(F) of this section);
(F) Enumerate all categories of IDCs to
be shared under the CSA;
(G) Specify that the controlled partic-
ipants must use a consistent method of
accounting to determine IDCs and RAB
shares, as described in paragraphs (d) and
(e) of this section, respectively, and must
translate foreign currencies on a consistent
basis;
(H) Require the controlled participants
to enter into CSTs covering all IDCs, as de-
scribed in paragraph (b)(2) of this section,
in connection with the CSA;
(I) Require the controlled participants
to enter into PCTs covering all external
contributions, as described in paragraph
(b)(3) of this section, in connection with
the CSA; and
(J) Specify the duration of the CSA,
the conditions under which the CSA may
be modified or terminated, and the conse-
quences of a modification or termination
(including consequences described under
the rules of paragraph (f) of this section).
(iii)Meaning of contemporaneous—
(A)In general. For purposes of this para-
graph (k)(1), a written contractual agree-
ment is contemporaneous with the forma-
tion (or revision) of a CSA if, and only if,
the controlled participants record the CSA,
in its entirety, in a document that they sign
and date no later than 60 days after the
first occurrence of any IDC described in
paragraph (d) of this section to which such
agreement (or revision) is to apply.
(B)Example. The following example
illustrates the principles of this paragraph
(k)(1)(iii):
Example. Companies A and B, both of which are
members of the same controlled group, commence
an IDA on March 1, Year 1. Company A pays the
first IDCs in relation to the IDA, as cash salaries to
A’s research staff, for the staff’s work during the first
week of March, Year 1. A and B, however, do not
sign and date any written contractual agreement un-
til August 1, Year 1, whereupon they execute a “Cost
Sharing Agreement” that purports to be “effective as
of” March 1 of Year 1. The arrangement fails the re-
quirement that the participants record their arrange-
ment i
n a written contractual agreement that is con-
temporaneous with the formation of a CSA.
(2)CSA documentation requirements
—(i)In general. The controlled partic-
ipants must timely update and maintain
sufficient documentation to establish that
the participants have met the CSA con-
tractual requirements of paragraph (k)(1)
of this section and the additional CSA doc-
umentation requirements of this paragraph
(k)(2).
(ii)Additional CSA documentation re-
quirements. The controlled participants to
a CSA must timely update and maintain
documentation sufficient to —
(A) Identify the cost shared intangibles
that the controlled participants have devel-
oped or intend to develop under the CSA,
together with each controlled participant’s
interest therein;
(B) Establish that each controlled par-
ticipant reasonably anticipates that it will
derive benefits from exploiting cost shared
intangibles;
(C) Describe the functions and risks that
each controlled participant has undertaken
during the term of the CSA;
(D) Provide an overview of each con-
trolled participant’s business segments, in-
cluding an analysis of the economic and le-
gal factors that affect CST and PCT pric-
ing;
(E) Establish the amount of each con-
trolled participant’s IDCs for each taxable
year under the CSA, including all IDCs
attributable to stock-based compensation,
as described in paragraph (d)(3) of this
section (including the method of measure-
ment and timing used in determining such
IDCs, and the data, as of the date of grant,
used to identify stock-based compensation
with the IDA);
(F) Describe the method used to es-
timate each controlled participant’s RAB
share for each year during the course of the
CSA, including —
(1) All projections used to estimate ben-
efits;
October 3, 20056712005–40 I.R.B.

(2) All updates of the RAB shares in
accordance with paragraph (e)(1) of this
section; and
(3) An explanation of why that method
was selected and why the method provides
the most reliable measure for estimating
RAB shares;
(G) Describe all external contributions,
as described in paragraph (b)(3)(ii) of this
section;
(H) Describe the RT for each PCT or
group of PCTs;
(I) Specify the form of payment due
under each PCT or group of PCTs;
(J) Describe and explain the method se-
lected to determine the arm’s length pay-
ment due under each PCT, including —
(1) An explanation of why the method
selected constitutes the best method, as de-
scribed in §1.482–1(c)(2), for measuring
an arm’s length result;
(2) The economic analyses, data, and
projections relied upon in developing and
selecting the best method, including the
source of the data and projections used;
(3) Each alternative method that was
considered, and the reason or reasons that
the alternative method was not selected;
(4) Any data that the controlled partic-
ipant obtains, after the CSA takes effect,
that would help determine if the controlled
participant’s method selected has been ap-
plied in a reasonable manner;
(5) The discount rate, where applicable,
used to value each payment due under a
PCT, and a demonstration that the discount
rate used is consistent with the principles
of paragraph (g)(2)(vi) of this section;
(6) The estimated arm’s length values
of any external contributions as of the
dates of the relevant PCTs, in accordance
with paragraph (g)(2)(ii) of this section;
(7) A discussion, where applicable, of
why transactions were or were not aggre-
gated under the principles of paragraph
(g)(2)(v) of this section;
(8) The method payment form and any
conversion made from the method pay-
ment form to the specified payment form,
as described in paragraph (g)(2)(ix) of this
section; and
(9) If applicable under paragraph
(i)(6)(iv) of this section, the WACC of
the controlled group that includes the con-
trolled participants.
(iii)Coordination rules and pro-
duction of documents—(A)Coordi-
nation with penalty regulations.See
§1.6662–6(d)(2)(iii)(D) regarding coordi-
nation of the rules of this paragraph (k)
with the documentation requirements for
purposes of the accuracy-related penalty
under section 6662(e) and (h).
(B)Production of documentation. Each
controlled participant must provide to the
Commissioner, within 30 days of a re-
quest, the items described in paragraphs
(k)(2) and (3) of this section. The time
for compliance described in this paragraph
(k)(2)(iii)(B) may beextended at the dis-
cretion of the Commissioner.
(3)CSA accounting requirements—(i)
In general. The controlled participants
must maintain books and records (and re-
lated or underlying data and information)
that are sufficient to —
(A) Establish that the controlled partic-
ipants have used (and are using) a consis-
tent method of accounting to measure costs
and benefits;
(B) Translate foreign currencies on a
consistent basis; and
(C) To the extent that the method mate-
rially differs from U.S. generally accepted
accounting principles, explain any such
material differences.
(ii)Reliance on financial accounting.
For purposes of this section, the controlled
participants may not rely solely upon
financial accounting to establish satisfac-
tion of the accounting requirements of this
paragraph (k)(3). Rather, the method of
accounting must clearly reflect income.
Thor Power Tools Co. v. Commissioner,
439 U.S. 522 (1979).
(4)CSA reporting requirements—(i)
CSA Statement. Each controlled partici-
pant must file with the Internal Revenue
Service, in the manner described in this
paragraph (k)(4), a “Statement of Con-
trolled Participant to §1.482–7 Cost Shar-
ing Arrangement” (CSA Statement) that
complies with the requirements of this
paragraph (k)(4).
(ii)Content of CSA Statement.The
CSA Statement of each controlled partic-
ipantmust—
(A) State that the participant is a con-
trolled participant in a CSA;
(B) Provide the controlled participant’s
taxpayer identification number;
(C) List the other controlled partici-
pants in the CSA, the country of organ-
ization of each such participant, and the
taxpayer identification number of each
such participant;
(D) Specify the earliest date that any
IDC described in paragraph (d)(1) of this
section occurred; and
(E) Indicate the date on which the con-
trolled participants formed (or revised) the
CSA and, if different from such date, the
date on which the controlled participants
recorded the CSA (or any revision) con-
temporaneously in accordance with para-
graphs (k)(1)(i) and (iii) of this section.
(iii)Time for filing CSA Statement—
(A)90-day rule. Each controlled partici-
pant must file its original CSA Statement
with the Internal Revenue Service Ogden
Campus, no later than 90 days after the
first occurrence of an IDC to which the
newly-formed CSA applies, as described
in paragraph (k)(1)(iii)(A) of this section,
or, in the case of a taxpayer that became
a controlled participant after the formation
of the CSA, no later than 90 days after such
taxpayer became a controlled participant.
A CSA Statement filed in accordance with
this paragraph (k)(4)(iii)(A) must be dated
and signed, under penalties of perjury, by
an officer of the controlled participant who
is duly authorized (under local law) to sign
the statement on behalf of the controlled
participant.
(B)Annual return requirement—(1)In
general. Each controlled participant must
attach to its U.S. income tax return, for
each taxable year for the duration of the
CSA, a copy of the original CSA Statement
that the controlled participant filed in ac-
cordance with the 90-day rule of paragraph
(k)(4)(iii)(A) of this section. In addition,
the controlled participant must update the
information reflected on the original CSA
Statement annually by attaching a sched-
ule that documents changes in such infor-
mation over time.
(2)Special filing rule for annual return
requirement. If a controlled participant is
notrequiredtofileaU.S.incometaxre-
turn, the participant must ensure that the
copy or copies of the CSA Statement and

any Form 5471, any Form 5472, or any
Form 8865, filed with respect to that par-
ticipant.
(iv)Examples. The following examples
illustrate this paragraph (k)(4). In each ex-
ample, Companies A and B are members
of the same controlled group. The exam-
ples are as follows:
Example 1. AandB,bothofwhichfileU.S.
tax returns, agree to share the costs of developing a
2005–40 I.R.B.672October 3, 2005

new chemical formula in accordance with the provi-
sions of this section. On March 30, Year 1, A and
B record their agreement in a written contract styled,
“Cost Sharing Agreement.” The contract applies by
its terms to IDCs occurring after March 1, Year 1.
The first IDCs to which the CSA applies occurred
on March 15, Year 1. To comply with paragraph
(k)(4)(iii)(A) of this section, A and B individually
must file separate CSA Statements no later than 90
days after March 15, Year 1 (June 13, Year 1). Fur-
ther, to comply with paragraph (k)(4)(iii)(B) of this
section, A and B must attach copies of their respec-
tive CSA Statements to their respective Year 1 U.S.
income tax returns.
Example 2. ThefactsarethesameasinExam-
ple 1, except that a year has passed and C, which
files a U.S. tax return, joined the CSA on May 9,
Year 2. To comply with the annual filing requirement
described in paragraph (k)(4)(iii)(B) of this section,
A and B must each attach copies of their respective
CSA Statements (as filed for Year 1) to their respec-
tive Year 2 income tax returns, along with a schedule
updated appropriately to reflect the changes in infor-
mation described in paragraph (k)(4)(ii) of this sec-
tion resulting from the addition of C to the CSA. To
comply with both the 90-day rule described in para-
graph (k)(4)(iii)(A) of this section and the annual fil-
ing requirement described in paragraph (k)(4)(iii)(B)
of this section, C must file a CSA Statement no later
than 90 days after May 9, Year 2 (August 7, Year 2),
and must attach a copy of such CSA Statement to its
Year 2 income tax return.
(l)Effective date. This section applies
on the date of publication of this document
as a final regulation in theFederal Regis-
ter.
(m)Transition rule—(1)In general.
Subject to paragraph (m)(2) of this sec-
tion, an arrangement in existence before
the date of publication of this document
as a final regulation in theFederal Reg-
isterwill be considered a CSA, as de-
scribed under paragraph (b) of this sec-
tion, if, prior to such date, it was a qual-
ified cost sharing arrangement under the
provisions of §1.482–7 (as contained in the
26 CFR part 1 edition revised as of January
1, 1996, hereafter referred to as “former
§1.482–7”), but only if the written con-
tract, as described in paragraph (k)(1) of
this section, is amended, if necessary, to
conform with the provisions of this sec-
tion, as modified by paragraph (m)(3) of
this section, by the close of the 120th day
after the date of publication of this docu-
ment as a final regulation in theFederal
Register.
(2)Termination of grandfather status.
Notwithstanding paragraph (m)(1) of this
section, an arrangement otherwise therein
described will not be considered a CSA
from the earliest of —
(i) A failure of the controlled partici-
pants to substantially comply with the pro-
visions of this section, as modified by para-
graph(m)(3)ofthissection;
(ii) A material change in the scope
of the arrangement, such as a material
expansion of the activities undertaken
beyond the scope of the intangible de-
velopment area, as described in former
§1.482–7(b)(4)(iv), as of the date of pub-
lication of this document as a final regula-
tion in theFederal Register;or
(iii) The date 50 percent or more of the
value of the interests in cost shared intan-
gibles are owned directly or indirectly by
a person or persons that were not direct or
indirect owners of such interests as of the
date of publication of this document as a
final regulation in theFederal Register.
(3)Transitional modification of appli-
cable provisions. For purposes of this
paragraph (m), conformity and substantial
compliance with the provisions of this sec-
tion shall be determined with the following
modifications:
(i) CSTs and PCTs occurring prior to
the date of publication of this document
as a final regulation in theFederal Reg-
istershall be subject to the provisions of
former §1.482–7 rather than this section.
Notwithstanding the foregoing, PCTs of a
CSA will be subject to the provisions of
this section if there is a Periodic Trigger for
such CSA for which a subsequent PCT, oc-
curring on or after the date of publication
of this document as a final regulation in the
Federal Register,istheTriggerPCT.
(ii) Paragraph (b)(1)(i) and paragraph
(b)(4) of this section shall not apply.
(iii) Paragraph (k)(1)(ii)(D) of this sec-
tion shall not apply.
(iv) Paragraph (k)(1)(ii)(H) and para-
graph (k)(1)(ii)(I) of this section shall be
construed as applying only to transactions
entered into on or after the date of publica-
tion of this document as a final regulation
in theFederal Register.
(v) The deadline for recordation of the
revised written contractual agreement pur-
suant to paragraph (k)(1)(iii) of this section
shall be no later than the 120th day after
the date of publication of this document as
a final regulation in theFederal Register.
(vi) Paragraphs (k)(2)(ii)(G) through (J)
of this section shall be construed as apply-
ing only with reference to PCTs entered
into on or after the date of publication of
this document as a final regulation in the
Federal Register.
(vii) Paragraph (k)(4)(iii)(A) shall be
construed as requiring a CSA Statement
with respect to the revised written con-
tractual agreement described in paragraph
(m)(3)(v) of this section no later than the
180th day after the date of publication of
this document as a final regulation in the
Federal Register.
(viii) Paragraph (k)(4)(iii)(B) shall
be construed as only applying for tax-
able years ending after the filing of the
CSA Statement described in paragraph
(m)(3)(vii) of this section.
Par. 9. Section 1.482–8 is amended by
addingExamples 10through15at the end
of the section to read as follows:
§1.482–8 Examples of the best method
rule.
*****
Example 10.Preference for acquisition price
method. (i) USP develops, manufacturers, and dis-
tributes ethical pharmaceutical products. USP and
FS, USP’s wholly-owned subsidiary, enter into a
CSA to develop a new oncological drug, Oncol.
Immediately prior to entering into the CSA, USP ac-
quires Company X, an unrelated U.S. pharmaceutical
company. Company X is solely engaged in oncolog-
ical pharmaceutical research, and its only significant
resources and capabilities are its workforce and its
sole patent, which is associated with Compound X,
a promising molecular compound derived from a
rare plant, which USP reasonably anticipates will
contribute to developing Oncol. All of Company X
researchers will be engaged solely in research that
is reasonably anticipated to contribute to developing
Oncol as well. The RT Rights in the Compound X
and the commitment of Company X’s researchers to
the development of Oncol are external contributions
for which compensation is due from FS as part of
a PCT. Under the terms of the CSA, USP is to be
compensated for its external contributions on a lump
sum basis.
(ii) In this case, the acquisition price method,
based on the lump sum price paid by USP for Com-
pany X, is likely to provide a more reliable measure
of an arm’s length PCT Payment due to USP than the
application of any other method.
Example 11.Preference for market capitaliza-
tion method. (i) Company X is a publicly traded U.S.
company solely engaged in oncological pharmaceuti-
cal research and its only significant resources and ca-
pabilities are its workforce and its sole patent, which
is associated with Compound Y, a promising molecu-
lar compound derived from a rare plant. Company X
has no marketable products. Company X enters into a
CSA with FS, a newly-formed foreign subsidiary, to
develop a new oncological drug, Oncol, derived from
Compound Y. Compound Y is reasonably anticipated
to contribute to developing Oncol. All of Company
X researchers will be engaged solely in research that
is reasonably anticipated to contribute to developing
October 3, 20056732005–40 I.R.B.

Oncol under the CSA. The RT Rights in Compound
Y and the commitment of Company X’s researchers
are external contributions for which compensation is
due from FS as part of a PCT. Under the terms of the
CSA, Company X is to be compensated for its exter-
nal contributions on a lump sum basis.
(ii) In this case, given that Company X’s exter-
nal contributions covered by PCTs relate to its entire
economic value, the application of the market capital-
ization method, based on the market capitalization of
Company X, is likely to provide a more reliable mea-
sure of an arm’s length result for Company X’s PCTs
to the CSA than the application of any other method.
Example 12.Preference for market capitaliza-
tion method. (i) MicroDent, Inc. (MDI) is a publicly
traded company that developed a new dental surgi-
cal microscope ScopeX–1, which drastically shortens
many surgical procedures. On January 1 of Year 1,
MDI entered into a CSA with a wholly-owned for-
eign subsidiary (FS) to develop ScopeX–2, the next
generation of ScopeX–1. The RT Rights associated
with ScopeX–1, as well as MDI’s research capabil-
ities are reasonably anticipated to contribute to the
development of ScopeX–2 and are therefore external
contributions for which compensation is due from FS
as part of a PCT. Under the terms of the CSA, MDI is
to be compensated for its external contributions on a
lump sum basis. At the time of the PCT, MDI’s only
product was the ScopeX-I microscope, although MDI
was in the process of developing ScopeX–2. Concur-
rent with the CSA, MDI separately transfers exclu-
sive and perpetual exploitation rights associated with
ScopeX–1 to FS in the same specified geographic
area as assigned to FS in the CSA.
(ii) Although the transactions between MDI and
FS under the CSA are distinct from the transactions
between MDI and FS relating to the exploitation
rights for ScopeX–1, it is likely to be more reliable
to evaluate the combined effect of the transactions
than to evaluate them in isolation. This is because
the combined transactions between MDI and FS
relate to all of the economic value of MDI (that is,
the exploitation rights and research rights associated
with ScopeX–1, as well as the research capabilities
of MDI). In this case, application of the market
capitalization method, based on the enterprise value
ofMDIonJanuary1ofYear1,islikelytoprovide
a more reliable measure of an arm’s length payment
for the aggregated transactions than the application
of any other method.
(iii) Notwithstanding that the market capitaliza-
tion method provides the most reliable measure of
the aggregated transactions between MDI and FS, see
paragraph (g)(2)(v) of this section for further consid-
erations of when further analysis may be required to
distinguish between the remuneration to MDI asso-
ciated with PCTs under the CSA (for research rights
and capabilities associated with ScopeX–1) and the
remuneration to MDI for the exploitation rights asso-
ciated with ScopeX–1.
Example 13.Income method (CPM-based) pre-
ferred to acquisition price method. The facts are the
same asExample 10, except that the acquisition oc-
curred significantly in advance of formation of the
CSA, and reliable adjustments cannot be made for
this time difference. In addition, Company X has
other valuable molecular patents and associated re-
search capabilities, apart from Compound Y, that are
not reasonably anticipated to contribute to the devel-
opment of Oncol and that cannot be reliably valued.
Under the terms of the CSA, USP will undertake all
R&D (consisting of laboratory research and clinical
testing) and manufacturing associated with Oncol, as
well as the distribution activities for its assigned area
(the United States). FS will distribute Oncol in its as-
signed area (the rest of the world). FS’s distribution
activities are routine in nature, and the profitability
from its activities may be reliably determined from
third-party comparables. FS does not furnish any ex-
ternal contributions. At the time of the PCT, reliable
(ex ante) financial projections associated with the de-
velopment of Oncol and its separate exploitation in
each of USP’s and FSub’s assigned geographical ter-
ritories are undertaken. Inthis case, application of
the income method is likely to provide a more reliable
measure of an arm’s length result than application of
the acquisition price method based on the price paid
by USP for Company X.
Example 14.Evaluation of alternative methods.
(i) The facts are the same asExample 10, except
that the acquisition occurred sometime prior to the
CSA, and Company X has some areas of promising
research that are not reasonably anticipated to con-
tribute to developing Oncol. In general, the Com-
missioner determines that the acquisition price data
is useful in informing the arm’s length price, but not
necessarily determinative. Under the terms of the
CSA, USP will undertake all R&D (consisting of lab-
oratory research and clinicaltesting) and manufactur-
ing associated with Oncol, as well as the distribution
activities for its assigned area (the United States). FS
will distribute Oncol in its assigned area (the rest of
the world). FS’s distribution activities are routine in
nature, and the profitability from its activities may be
reliably determined from third-party comparables. At
the time of the PCT, financial projections associated
with the development of Oncol and its separate ex-
ploitation in each of USP’s and FSub’s assigned ge-
ographical territories are undertaken.
(ii) Under the facts, it is possible that the acquisi-
tion price method or the CPM-based income method
might reasonably be applied. Whether the acquisi-
tion price method or the income method provides the
most reliable evidence of the arm’s length price of
USP’s contributions depends on a number of factors,
including the reliability of the financial projections,
the reliability of the discount rate chosen, and the ex-
tent to which the acquisition price of Company X can
be reliably adjusted to account for changes in value
over the time period between the acquisition and the
formation of the CSA and to account for the value of
the in-process research done by Company X that does
not constitute external contributions to the CSA.
Example 15.Evaluation of alternative methods.
(i) The facts are the same asExample 14, except that
FS has a patent on Compound Y, which the parties
reasonably anticipate will be useful in mitigating po-
tential side effects associated with Compound X and
thereby contribute to the development of Oncol. The
RT Rights in Compound Y constitute an external con-
tribution for which compensation is due from USP as
part of a PCT. The value of FS’s external contribution
cannot be reliably measured by market benchmarks.
(ii) Under the facts, it is possible that either the
acquisition price method and the income method to-
gether or the residual profit split method might rea-
sonably be applied to determine the arm’s length PCT
Payments due between USP and FS. Under the first
option the PCT Payment for the external contribu-
tions related to Company X’s workforce and Com-
pound X would be determined using the acquisition
price method referring to the lump sum price paid by
USP for Company X. Because the value of these ex-
ternal contributions can be determined by reference
to a market benchmark, they are considered routine
external contributions. Accordingly, under this op-
tion, the external contribution related to Compound
Y would be the only nonroutine external contribution
and the relevant PCT Payment is determined using
the income method. Under the second option, rather
than looking to the acquisition price for Company X,
all the external contributions are considered nonrou-
tine and the RPSM is applied to determine the PCT
Payments for each external contribution. Under ei-
ther option, the PCT Payments will be netted against
each other.
(iii) Whether the acquisition price method to-
gether with the income method or the residual profit
split method provides the most reliable evidence of
the arm’s length price of the external contributions of
USP and FS depends on a number of factors, includ-
ing the reliability of the determination of the relative
values of the external contributions for purposes of
the RPSM, and the extent to which the acquisition
price of Company X can be reliably adjusted to
account for changes in value over the time period
between the acquisition and the formation of the
CSA and to account for the value of the RT Rights
in the in-process research done by Company X that
does not constitute external contributions to the CSA.
In these circumstances, it is also relevant to consider
whether the results of each method are consistent
with each other, or whether one or both methods are
consistent with other potential methods that could be
applied.

Certain Section 951 Pro Rata
Share Allocations
REG–129782–05
AGENCY: Internal Revenue Service
(IRS), Treasury.
ACTION: Notice of proposed rulemaking.
SUMMARY: This document contains pro-
posed amendments to regulations under
section 951(a) of the Internal Revenue
Code (Code) regarding a United States
shareholder’spro ratashare of a controlled
foreign corporation’s (CFC’s) subpart F
income, previously excluded subpart F
income withdrawn from investment in less
developed countries, and previously ex-
cluded subpart F income withdrawn from
foreign base country shipping operations.
These proposed regulations are intended
to ensure that a CFC’s earnings and profits
for a taxable year attributable to a section
304 transaction will not be allocated in
a manner that results in the avoidance
of Federal income tax. These proposed
regulations are also intended to ensure
that earnings and profits of a CFC are not
allocated to certain preferred stock in a
manner inconsistent with the economic
interest that such stock represents.
DATES: Written or electronic comments
and requests for a public hearing must be
received by October 24, 2005.

SUPPLEMENTARY INFORMATION:
Background
This document contains proposed
amendments to 26 CFR part 1 under
section 951(a) of the Code relating to the
determination of a United States share-
holder’spro ratashare of a CFC’s subpart
F income, previously excluded subpart F
income withdrawn from investment in less
developed countries, and previously ex-
cluded subpart F income withdrawn from
foreign base country shipping operations.
In general, section 951(a)(1) requires a
United States shareholder that owns stock
in a CFC to include itspro ratashare of
such amounts in its gross income.Pro rata
share is defined in section 951(a)(2) of the
Code as the amount:
(A) Which would have been distributed
with respect to the stock which such share-
holder owns (within the meaning of sec-
tion 958(a)) in such corporation if on the
last day in its taxable year on which the
corporation is a CFC it had distributedpro
ratato its shareholders an amount which
bears the same ratio to its subpart F in-
come for the taxable year, as the part of
such year during which the corporation is
a CFC bears to the entire year, reduced by
(B) The amount of distributions re-
ceivedbyanyotherpersonduringsuch
year as a dividend with respect to such
stock, but only to the extent of the div-
idend which would have been received
if the distribution by the corporation had
been the amount which bears the same
ratio to the subpart F income of such cor-
poration for the taxable year, as the part of
such year during which such shareholder
did not own (within the meaning of section
958(a)) such stock bears to the entire year.
A CFC’s earnings and profits are al-
located among different classes of the
CFC’s stock for the purpose of deter-
mining thepro ratashare of the CFC’s
subpart F income or withdrawal of pre-
viously excluded subpart F income of a
United States shareholder of such CFC
October 3, 20056752005–40 I.R.B.

under §1.951–1(e). The IRS and Treasury
Department are aware of certain trans-
actions in which a CFC’s earnings and
profits and subpart F income for a taxable
year are increased by a deemed dividend
arising from a transaction described in
section 304, with respect to which tax-
payers take the position that the current
regulations permit the allocation of earn-
ings and profits between different classes
of stock (e.g., common stock and preferred
stock) in a manner inconsistent with the
economic interests in the CFC represented
by the respective classes of stock. The
IRS and Treasury Department believe
that such allocations are inconsistent with
the policies underlying subpart F. These
proposed regulations would provide addi-
tional guidance to ensure results that are
consistent with such economic interests.
Responding to regulations proposed
under section 951 on August 6, 2004, and
published in final form (T.D. 9222) in this
issue of the Bulletin (REG–129771–04,
2004–2 C.B. 453), a commentator ob-
served that U.S. shareholders of CFCs
sometimes have caused mandatorily re-
deemable preferred stock with cumula-
tive dividend rights to be issued to (or
otherwise acquired by) foreign persons.
Relying on the fact that the hypotheti-
cal distribution rule does not take into
account the time value of money, the
parties in these transactions provide a rela-
tively high dividend rate on such stock but
forego compounding on the accrued but
unpaid dividends, which would generally
be required in an arms’ length transaction.
This would inappropriately deflect subpart
F income inclusions with respect to the
U.S. shareholder’s stock in the CFC. To
address this concern, the proposed regula-
tions provide a special allocation rule for
such stock which would appropriately dis-
count the amount of earnings and profits
allocated to the preferred stock in annual
hypothetical distributions.
Explanation of Provisions
A.Earnings and profits from certain
section 304 transactions
Section 1.951–1(e) definespro rata
share for purposes of section 951(a) of the
Code. Proposed §1.951–1(e)(3)(v) adds
a special rule that would modify the gen-
eral rule of §1.951–1(e)(3)(i) regarding
the allocation of a CFC’s current earn-
ings and profits to more than one class of
stock. The general rule provides for the
allocation of current earnings and profits
to different classes of stock on the basis of
the respective amounts of such earnings
and profits that would be distributed with
respect to each class if such earnings and
profits were distributed on the last day of
theCFC’staxableyearonwhichitisa
CFC.
The special rule applies where a CFC
has earnings and profits and subpart F in-
come for its taxable year attributable to a
transaction described in section 304 of the
Code and that transaction is part of a plan
a principal purpose of which is to avoid
Federal income taxation by allocating the
subpart F income resulting from the sec-
tion 304 transaction disproportionately to a
tax-indifferent party. Pursuant to the rule,
such earnings and profits will be allocated
to each class of stock of the CFC in accor-
dance with the value of such class relative
to all other classes.
In the absence of the special rule, the
current earnings and profits of a CFC hav-
ing a class of preferred stock with a fixed
return and a class of common stock would
be allocated under the general rule on the
basis of a hypothetical distribution. Thus,
the preferred stock would receive an allo-
cation equal to the amount of the fixed re-
turn on the total investment in such stock,
and the common stock would receive an
allocation of the remainder of the earn-
ings and profits. This result would not
reflect the actual economic interest in the
CFC of the respective classes of stock in
a case where the earnings and profits were
artificially inflated as a result of the divi-
dend arising from the section 304 transac-
tion. The amount allocated to the preferred
stock in such a case under the general rule
would be a significantly smaller percent-
age of the total than the percentage of the
corporation’s value represented by the pre-
ferred stock.
This is illustrated by the example that
would be added to §1.951–1(e)(6) by these
proposed regulations. By modifying the
allocation of earnings and profits to classes
of stock in this limited category of cases,
the proposed regulations ensure that the al-
location will be consistent with the eco-
nomic interest in the CFC represented by
the respective classes of stock.
B.Certain cumulative preferred stock
Proposed §1.951–1(e)(4)(ii) would add
a special rule that would determine the
hypothetical distribution of earnings and
profits with respect to cumulative pre-
ferred stock with a mandatory redemption
date by reflecting the present value of ac-
crued but unpaid dividends with respect
to such stock, determined generally on
the basis of the implied annual rate of re-
turn on such stock and the length of time
between the current year’s hypothetical
distribution date and the mandatory re-
demption date. This special rule would
apply only if the rate of compounding on
the accrued but unpaid cumulative divi-
dends would be less than the appropriate
applicable Federal rate and if a distribution
on the stock would not be included in the
gross income of a United States taxpayer.
Proposed Effective Dates
Sections1.951–1(e)(3)(v)and
1.951–1(e)(4)(ii) are proposed to apply
for taxable years of a controlled foreign
corporation beginning on or after January
1, 2006.
Special Analyses
It has been determined that this notice
of proposed rulemaking is not a significant
regulatory action as defined in Executive
Order 12866. Therefore, a regulatory as-
sessment is not required. It has also been
determined that section 553(b) of the Ad-
ministrative Procedure Act (5 U.S.C. chap-
ter 5) does not apply to these regulations
and because these regulations do not im-
pose a collection of information on small
entities, a Regulatory Flexibility Analy-
sis under the Regulatory Flexibility Act
(5 U.S.C. chapter 6) does not apply. Pur-
suant to section 7805(f) of the Code, this
notice of proposed rulemaking will be sub-
mitted to the Chief Counsel for Advocacy
of the Small Business Administration for
comment on its impact on small business.
Comments and Requests for Public
Hearing
Before these proposed regulations are
adopted as final regulations, considera-
tion will be given to any written (a signed
original and eight (8) copies) or electronic
comments that are submitted timely to the
2005–40 I.R.B.676October 3, 2005

IRS. The IRS and Treasury Department
specifically request comments regarding
appropriate rules for determining under
section 951 the hypothetical distribution
of earnings and profits for cumulative pre-
ferred stock that does not have a manda-
tory redemption date, or that is subject
to a shareholder-level agreement, such as
a purchase option, to take into account
the present value of accrued but unpaid
dividends. The IRS and Treasury De-
partment contemplate that if promulgated,
such rules would be effective for taxable
years of a controlled foreign corporation
beginning on or after January 1, 2006.
The IRS and Treasury Department also
request comments on the clarity of the pro-
posed rules and how they can be made eas-
ier to understand. All comments will be
available for public inspection and copy-
ing. A public hearing will be scheduled
if requested in writing by any person who
timely submits written comments. If a
public hearing is scheduled, notice of the
date, time, and place of the hearing will be
published in theFederal Register.

Proposed Amendments to the
Regulations
Accordingly, 26 CFR part 1 is proposed
to be amended as follows:
PART 1—INCOME TAXES
Par. 1. The authority citation for part 1
continues to read, in part, as follows:
Authority: 26 U.S.C. 7805 * * *
Par. 2. Section 1.951–1 is amended
by revising paragraphs (e)(3)(v), (e)(4)(ii),
(e)(6)Example 9, and (e)(7).
The revisions read as follows:
§1.951–1 Amounts included in gross
income of United States shareholders.
*****
(e) * * *
(3) * * *
(v)Earnings and profits attributable to
certain section 304 transactions. For tax-
able years of a controlled foreign corpo-
ration beginning on or after January 1,
2006, if a controlled foreign corporation
has more than one class of stock outstand-
ing and the corporation has earnings and
profits and subpart F income for a taxable
year attributable to a transaction described
in section 304, and such transaction is part
of a plan a principal purpose of which is
the avoidance of Federal income taxation,
the amount of such earnings and profits al-
located to any one class of stock shall be
that amount which bears the same ratio to
the remainder of such earnings and profits
as the value of all shares of such class of
stock, determined on the hypothetical dis-
tribution date, bears to the total value of all
shares of all classes of stock of the corpo-
ration, determined on the hypothetical dis-
tribution date.
(4)***(i)***
(ii)Certain cumulative preferred stock.
For taxable years of a controlled foreign
corporation beginning on or after January
1, 2006, if a controlled foreign corpora-
tion has one or more classes of preferred
stock with a mandatory redemption date
and cumulative dividend rights, arrear-
ages on which compound at a rate less
than an annual compounding at the appli-
cable Federal rate (as defined in section
1274(d)(1)) (AFR) that applies on the date
the stock is issued for the term from such
issuedatetothemandatoryredemption
date, then, to the extent that—
(A) A distribution with respect to such
stock on the hypothetical distribution date
would not be includible in the gross in-
come of a citizen or individual resident of
the United States, a domestic corporation,
or a foreign person as income effectively
connected with such foreign person’s con-
duct of a trade or business in the United
States; and
(B) Any dividends accruing with re-
spect to such stock during the taxable year
of the controlled foreign corporation have
not been paid during such taxable year (ac-
crued but unpaid dividends), the amount of
earnings and profits that shall be consid-
ered to be distributed as part of the hypo-
thetical distribution for purposes of para-
graph (e)(3)(i) of thissection with respect
to such stock shall be equal to the present
value of such accrued but unpaid dividends
for the taxable year. The present value of
such accrued but unpaid dividends for the
taxable year is determined for the purposes
of this paragraph by discounting such ac-
crued but unpaid dividends for that taxable
year from the mandatory redemption date
to the hypothetical distribution date using
the implied annual rate of return on an in-
vestment at par in a share of such stock
that is held from the date of issue until
the mandatory redemption date, on the as-
sumption that no dividends with respect to
the stock are paid prior to redemption.
*****
(6) * * *
Example 9.(i)Facts. In 2006, FC10, a con-
trolled foreign corporation within the meaning of sec-
tion 957(a), has outstanding 100 shares of common
stock and 100 shares of 6-percent, voting, preferred
stock with a par value of $10x per share. All of the
common stock is held by Corp H, a foreign corpo-
ration which invested $1000x in FC10 in exchange
for the common stock. All of FC10’s preferred stock
is held by Corp J, a domestic corporation which in-
vested $1000x in FC10 in exchange for the FC10
preferred stock. The value of the common stock of
FC10 at all relevant times is $1000x and the value
of the preferred stock of FC10 at all relevant times
is also $1000x. In 2006, FC10 borrows $3000x from
a bank and invests $5000x in preferred stock issued
by FC11, a foreign corporation owned by Corp J.
FC11, which has no current or accumulated earnings
and profits, uses the proceeds to lend $5000x to Corp
J. In 2008, FC10 sells the FC11 preferred stock to
FC12, a wholly owned foreign subsidiary of FC11
that has $5000x of accumulated earnings and prof-
its, for $5000x in a transaction described in section
304. FC10 repays the bank loan in full. The acqui-
sition and sale of the FC11 preferred stock by FC10
was part of a plan a principal purpose of which was
the avoidance of Federal income tax. For 2008, FC10
has $5000x of earnings and profits, all of which is
subpart F income attributable to a deemed dividend
arising from FC10’s sale of the FC11 preferred stock
to FC12.
(ii)Analysis. FC10 has $5000x of earnings and
profits for 2008 attributable to a dividend from a sec-
tion 304 transaction which was part of a plan a prin-
cipal purpose of which was the avoidance of Federal
income taxation. Under paragraph (e)(3)(v) of this
section, these earnings and profits are allocated to the
common and preferred stock of FC10 in accordance
with the relative value of each class of stock. Thus,
for taxable year 2008, $2500x is allocated to FC10’s
common stock and $2500x is allocated to its preferred
stock.
(7)Effective dates. Except as provided
in paragraphs (e)(3)(v) and (e)(4)(ii) of this
section, this paragraph (e) applies for tax-
able years of a controlled foreign corpora-
tion beginning on or after January 1, 2005.

Disaster Relief for Issuers of
Tax-Exempt Bonds Affected
by Hurricane Katrina
Announcement 2005–69
In view of the extreme need for relief
in the aftermath of Hurricane Katrina, is-
suers of tax-exempt bonds may be unable

in Mississippi, Alabama, and Florida that
have been or are later designated as disas-
ter areas because of devastation caused by
Hurricane Katrina are collectively referred
to herein as the “covered counties”.
PROCEDURES FOR REQUESTING
RELIEF
a. An affected issuer is an issuer that
meets one or more of the following:
i. It is located in one of the covered
counties;
ii. It is not located in any of the covered
counties, but its records necessary to
meet a filing or paying deadline for
the issue are maintained in one of the
covered counties;
iii. The facilities financed with the pro-
ceeds of the issue are located in one
of the covered counties;
iv. The conduit borrower for the issue is
located in one of the covered counties;
v. The counsel to the issuer or the con-
duit borrower, or bond counsel for the
issue, is located in one of the covered
counties;
vi. The professional on whom the issuer
relies for compliance with the relevant

of section 148(f): the bond trustee, fi-
nancial advisor or a rebate consultant.
(b) With respect to the requirements un-
der sections 149(e) and 148(f), an affected
issuer has until January 3, 2006 to file

case of a Form 8038-T, the Service will
not impose a penalty, including any inter-
est portion thereof, under section 148 of
the Code, on rebate payments, yield reduc-
tion payments and penalties in lieu of re-
bate that are originally due on or after Au-
gust 29, 2005, and on or before Decem-
ber 31, 2005, provided such payments are
made by January 3, 2006. For computation
purposes, such payments will be treated as
paid on the last day of the computation or
spending period to which they relate.
(c) When filing a form described in
subsection (b) above, the affected issuer
should add the following designation in
red ink at the top of the form, “Hurri-
cane Katrina Relief, See Announcement
2005–69.”

subsection (b) above, other relief may
also be granted under appropriate circum-
stances for affected issuers (for example,

The relief provided under this announce-
ment is in addition to the relief already
provided by the Service pursuant to News
Release IR–2005–96 under § 7508A of
the Internal Revenue Code (“Code”) for
victims of Hurricane Katrina. (See the
regulations under § 7508A and Section 8
of Rev. Proc. 2005–27, 2005–20 I.R.B.
1050, for a listing of employee bene-
fit-related acts currently postponed until
January 3, 2006, because of the disaster.)
Background
The laws relating to qualified em-
ployer plans impose various limitations
on the permissibility of distributions and
loans from those plans. For example,
§ 401(k)(2)(B)(i) of the Code provides
that in the case of a § 401(k) plan that is
part of a profit-sharing or stock bonus plan,
elective deferrals may only be distributed
in certain situations, one of which is on
account of hardship. Section 403(b)(11)
provides similar rules with respect to elec-
tive deferrals under a § 403(b) plan. Other
rules do not permit in-service distribu-
tions from certain plans, even if there
is a hardship. For example, in-service
hardship distributions are generally not
permitted from pension plans or from
accounts holding qualified nonelective
contributions (“QNECs”) described in
§ 401(m)(4)(C) or qualified matching
contributions (“QMACs”) described in
§ 401(k)(3)(D)(ii)(I). However, Rev. Rul.
2004–12, 2004–1 C.B. 478, holds that if
amounts attributable to rollover contribu-
tions are separately accounted for within
a plan, such amounts may be distributed
at any time, pursuant to the employee’s
request. Section 72(p) imposes certain re-
quirements relating to plan loans. Unless
those requirements are satisfied, a loan is
treated as a distribution under the plan.
In order to make a loan or distribution
(including a hardship distribution), the
plan must contain language authorizing
such loan or distribution. Also, except
to the extent a distribution consists of al-
ready-taxed amounts, the distribution will
be includible in gross income and gener-
ally subject to the 10-percent additional
tax under § 72(t). Similar rules apply to a
distribution from an IRA.
Plan provisions and regulations under
certain Code sections establish verification
procedures before distributions or loans
will be made from the plan. For example,
the regulations under § 401(k) set forth cer-
tain criteria an employee must meet in or-
der to receive a hardship distribution. A
plan may contain procedures designed to
confirm that the criteria have been satis-
fied.
Relief
A qualified employer plan will not be
treated as failing to satisfy any require-
ment under the Code or regulations merely
because the plan makes a loan, or a hard-
ship distribution for a need arising from
Hurricane Katrina, to an employee or for-
mer employee whose principal residence
on August 29, 2005, was located in one
of the counties or parishes in Louisiana,
Mississippi or Alabama that have been
or are later designated as disaster areas
eligible for Individual Assistance by the
Federal Emergency Management Agency
because of the devastation caused by Hur-
ricane Katrina or whose place of employ-
ment was located in one of these counties
or parishes on such date or whose lineal
ascendant or descendant, dependent or
spouse had a principal residence or place
of employment in one of these counties
or parishes on such date. Plan administra-
tors may rely upon representations from
the employee or former employee as to
the need for and amount of a hardship
distribution, unless the plan administrator
has actual knowledge to the contrary, and
such distribution is treated as a hardship
distribution for all purposes under the
Code and regulations. For purposes of
this announcement, a “qualified employer
plan” means a plan or contract meeting
the requirements of § 401(a), 403(a) or
403(b), and, for purposes of the hard-
ship relief, which could, if it contained
enabling language, make hardship distri-
butions. For purposes of this paragraph,
a “qualified employer plan” also means
a plan described in § 457(b) maintained
by an eligible employer described in
§ 457(e)(1)(A), and any hardship arising
from Hurricane Katrina is treated as an
“unforeseeable emergency” for purposes
of distributions from such plans. For ex-
ample, a profit-sharing or stock bonus
plan that currently does not provide for
hardship or other in-service distributions
may nevertheless make Katrina-related
hardship distributions pursuant to this
announcement, except from QNEC or
QMAC accounts or from earnings on elec-
tive contributions. A defined benefit or
money purchase plan, which generally
cannot make in-service hardship distribu-
tions, may not make hardship distributions
pursuant to this announcement, other than
from a separate account, if any, within
such plan containing either employee con-
tributions or rollover amounts.
The amount available for hardship
distribution is limited to the maximum
amount that would be permitted to be
available for a hardship distribution under
the plan under the Code and regulations.
However, the relief provided by this an-
nouncement applies to any hardship of the
employee, not just the types enumerated
in the regulations, and no post-distribu-
tion contribution restrictions are required.
For example, regulations under § 401(k)
provide safe harbor hardship distribution
standards wherein a hardship is deemed to
exist only for certain enumerated events,
and after receipt of the hardship amount,
the employee is prohibited from making
contributions for at least 6 months. Plans
need not follow these rules with respect
to hardship distributions described in the
2005–40 I.R.B.682October 3, 2005

first two sentences in the immediately
preceding paragraph.
If the plan does not provide for loans
or hardship distributions, the plan must be
amended to provide for loans or such emer-
gency distributions no later than the end of
the first plan year beginning after Decem-
ber 31, 2005. To qualify for the relief un-
der this announcement, a hardship distri-
bution must be made on account of a hard-
ship resulting from Hurricane Katrina and
be made on or after August 29, 2005, and
no later than March 31, 2006. In the case of
plan loans made pursuant to this announce-
ment, such loans must satisfy the require-
ments of § 72(p).
In addition, a retirement plan will not
be treated as failing to follow procedural
requirements for plan distributions (in
the case of all retirement plans, including
IRAs) or loans (in the case of retirement
plans other than IRAs) imposed by the
terms of the plan, merely because such re-
quirements are disregarded for any period
beginning on or after August 29, 2005,
and continuing through March 31, 2006,
with respect to distributions to individuals
described in the first paragraph under “Re-
lief”, provided the plan administrator (or
financial institution in the case of distribu-
tions from IRAs) makes a good-faith effort
under the circumstances to comply with
such requirements. However, as soon as
practical, the plan administrator (or finan-
cial institution in the case of IRAs) must
make a reasonable attempt to assemble
any foregone documentation. For ex-
ample, if spousal consent is required for a
plan loan or distribution and the plan terms
require production of a death certificate
if the employee claims his or her spouse
is deceased, the plan will not be disqual-
ified for failure to operate in accordance
with its terms if it makes a distribution or
loan to an individual described in the first
paragraph under “Relief” in the absence
of a death certificate if it is reasonable
to believe, under the circumstances, that
the spouse is deceased, the distribution is
made no later than March 31, 2006, and
the plan administrator makes reasonable
efforts to obtain the death certificate as
soon as practical. For purposes of this
announcement, “retirement plan” has the
same meaning as “eligible retirement
plan” under § 402(c)(8)(B).
The Department of Labor has advised
Treasury and the Internal Revenue Service
that it will not treat any person as hav-
ing violated the provisions of Title I of
the Employee Retirement Income Security
Act solely because they complied with the
provisions of this announcement.

Definition of Terms
Revenue rulings and revenue procedures
(hereinafter referred to as “rulings”) that
have an effect on previous rulings use the
following defined terms to describe the ef-
fect:
Amplifieddescribes a situation where
no change is being made in a prior pub-
lished position, but the prior position is be-
ingextendedtoapplytoavariationofthe
fact situation set forth therein. Thus, if
an earlier ruling held that a principle ap-
plied to A, and the new ruling holds that the
same principle also applies to B, the earlier
ruling is amplified. (Compare withmodi-
fied,below).
Clarifiedis used in those instances
where the language in a prior ruling is be-
ing made clear because the language has
caused, or may cause, some confusion.
It is not used where a position in a prior
ruling is being changed.
Distinguisheddescribes a situation
where a ruling mentions a previously pub-
lished ruling and points out an essential
difference between them.
Modifiedis used where the substance
of a previously published position is being
changed. Thus, if a prior ruling held that a
principle applied to A but not to B, and the
new ruling holds that it applies to both A
and B, the prior ruling is modified because
it corrects a published position. (Compare
withamplifiedandclarified, above).
Obsoleteddescribes a previously pub-
lished ruling that is not considered deter-
minative with respect to future transac-
tions. This term is most commonly used in
a ruling that lists previously published rul-
ings that are obsoleted because of changes
in laws or regulations. A ruling may also
be obsoleted because the substance has
been included in regulations subsequently
adopted.
Revokeddescribes situations where the
position in the previously published ruling
is not correct and the correct position is
beingstatedinanewruling.
Supersededdescribes a situation where
the new ruling does nothing more than re-
state the substance and situation of a previ-
ously published ruling (or rulings). Thus,
the term is used to republish under the
1986 Code and regulations the same po-
sition published under the 1939 Code and
regulations. The term is also used when
it is desired to republish in a single rul-
ing a series of situations, names, etc., that
were previously published over a period of
time in separate rulings. If the new rul-
ing does more than restate the substance
of a prior ruling, a combination of terms
is used. For example,modifiedandsu-
persededdescribes a situation where the
substance of a previously published ruling
is being changed in part and is continued
without change in part and it is desired to
restate the valid portion of the previously
published ruling in a new ruling that is self
contained. In this case, the previously pub-
lished ruling is first modified and then, as
modified, is superseded.
Supplementedis used in situations in
which a list, such as a list of the names of
countries, is published in a ruling and that
list is expanded by adding further names in
subsequent rulings. After the original rul-
ing has been supplemented several times, a
new ruling may be published that includes
the list in the original ruling and the ad-
ditions, and supersedes all prior rulings in
the series.
Suspendedis used in rare situations
to show that the previous published rul-
ings will not be applied pending some
future action such as the issuance of new
or amended regulations, the outcome of
cases in litigation, or the outcome of a
Service study.
