Questão jurídica principal
Whether the pension foundation and the Sicherheitsfonds had standing and validly held the assigned BVG responsibility claims.
Decisão extraída
The foundation retained standing through valid assignment and re-assignment; the Sicherheitsfonds also had standing due to its own protected financial interest.
Fundamentação extraída
The reassignment covered responsibility claims under Art. 52 BVG, while claims belonging to the Sicherheitsfonds in its own right were excluded from that reassignment and were not needed for the foundation's standing.
