Question juridique clé
Whether the exit benefit under the pension plan had to include interest on pre-2005 lump-sum contributions
Solution extraite
The earlier lump-sum contributions did not have to be interest-bearing under the plan; the regulatory gap was filled by analogy to Art. 17(4) FZG, excluding interest.
Motifs extraits
The 2003 regulations addressed only contribution-based payments under the new system and contained no transitional rule for earlier total contributions. Reading a duty to split and reallocate the former total contribution into savings and risk portions would improperly interfere with the pension fund's protected autonomy and financing model.
