Kernrechtsfrage
Whether the employer must pay outstanding BVG contributions, interest, and reminder fees
Extrahierter Entscheid
The court held that the documented contribution claims were proven and enforceable, and that contractual reminder fees were owed.
Extrahierte Begründung
The affiliation agreement and BVG provisions obliged the employer to pay contributions; the invoices substantiated the principal debt, and the contract provided for reminder charges.
