Kernrechtsfrage
Whether the collective outgoing group had a proportional claim to technical provisions in the partial liquidation.
Extrahierter Entscheid
Yes. The outgoing collective was entitled to a proportional share of the technical provisions for mortality/longevity, risk fluctuation, early retirement, and pending disability cases where actuarial risks were transferred.
Extrahierte Begründung
For collective exits, the decisive perspective is the transferring pension fund. Equal treatment under Art. 53d BVG requires that the outgoing collective receive a proportional share of provisions if those provisions were built to cover risks that leave with the group.
