Rev. Proc. 2015-52

SECTION 1. PURPOSE
This revenue procedure prescribes the loss payment patterns and discount factors for the
2015 accident year. These factors will be used to compute discounted unpaid losses under § 846
of the Internal Revenue Code. See Rev. Proc. 2012-44, 2012-49 I.R.B. 645, for background
concerning the loss payment patterns and application of the discount factors.
SECTION 2. SCOPE
This revenue procedure applies to any taxpayer that is required to discount unpaid losses
under § 846 for a line of business using the discount factors published by the Secretary.
SECTION 3. TABLES OF DISCOUNT FACTORS
.01 The following tables present separately for each line of business the discount factors
under § 846 for accident year 2015. All the discount factors presented in this section were

2
determined using the applicable interest rate under § 846(c) for 2015, which is 1.68 percent, and
by assuming all loss payments occur in the middle of the calendar year.
.02 If the groupings of individual lines of business on the annual statement change,
taxpayers must discount unpaid losses on the resulting line of business in accordance with the
discounting patterns that would have applied to those unpaid losses based on their classification
on the 2010 annual statement. See Rev. Proc. 2012-44, 2012-49 I.R.B. 645, section 2, for
additional background on discounting under § 846 and the use of the Secretary's tables.
.03 Section V of Notice 88-100, 1988-2 C.B. 439, sets forth a composite method for
computing discounted unpaid losses for accident years that are not separately reported on the
annual statement. The tables separately provide discount factors for taxpayers who elect to use
the composite method of section V of Notice 88-100. See Rev. Proc. 2002-74, 2002-2 C.B. 980.
