Kernrechtsfrage
What restitution value the foundation must transfer after early termination of the affiliation contract, especially for ongoing old-age pensions and alleged surplus pensions.
Extrahierter Entscheid
The cantonal court could not determine from the record whether the employer received the restitution value due under the contractual rules; the judgment had to be annulled and the case remanded for further fact-finding.
Extrahierte Begründung
The applicable framework was contractual because, before 2004, neither the BVG nor the FZG regulated the situation of pension beneficiaries upon termination of an affiliation contract. The existing file did not show how the amounts for the 'surplus pensions' were funded, secured, or why they were excluded from the mathematical reserve. The factual basis was therefore incomplete, preventing a lawful decision.
