Key legal question
Whether underfunding may be proportionally deducted from the full vested benefits in a partial liquidation.
Extracted holding
Yes. In a partial liquidation, the technical deficit may be deducted proportionally from the full exit benefits, provided the accrued old-age savings are not reduced.
Extracted reasoning
The statutory comparison calculation under FZG does not exclude the application of Art. 53d BVG; the deficit concerns the entire vested benefit, not only capital accumulated in the fund. This allocation is consistent with the structure of the law, the nature of underfunding, and equal treatment.
