Susan Muffley Act of 2025

S 1950, the Susan Muffley Act of 2025, requires the Pension Benefit Guaranty Corporation (PBGC) to recalculate guaranteed monthly pension benefits for participants and beneficiaries in six specific Delphi-related pension plans (including the Delphi Hourly-Rate Employees Pension Plan and Delphi Retirement Program for Salaried Employees). It mandates that benefits be calculated based on the "full vested plan benefit" amount - previously reduced under certain limits - rather than the prior calculation method. The PBGC must adjust future monthly payments and make lump-sum payments within 180 days to cover past underpayments, including 6% annual interest on each underpaid month. This directly affects current and future retirees in these terminated plans who received less than their full guaranteed benefit.
