Question juridique clé
Whether the appeal was admissible despite later reductions of the BVG minimum interest rate.
Solution extraite
The appellant retained a current practical interest because it still sought approval of the spread between the prescribed minimum rate and the risk-free return.
Motifs extraits
The later lowering of the statutory minimum did not eliminate the live controversy, since the requested tariff still depended on the difference between the legal minimum and actual portfolio returns.
