The Susan Muffley Act of 2025 aims to enhance pension benefits for participants and beneficiaries of certain pension plans, particularly those affected by terminations. This legislation ensures that individuals receive their full entitled benefits, especially in cases where previous calculations limited their payouts. Key provisions require the Pension Benefit Guaranty Corporation (PBGC) to recalculate monthly benefits for eligible participants, ensuring they receive the total amount they are entitled to without being hindered by previous caps or phase-in limits.
