Employers are facing problems with pension schemes due to falling asset values and low gilt yields, which have increased past service deficits. Common strategies to address this include reducing benefits for pensioners and deferred members through commutation or enhanced transfer values. Future service benefits can also be changed by reducing accrual rates, moving to career average salaries, increasing pension ages, or implementing salary sacrifice. Employers must consult trustees and members on any proposed changes and consider alternative options to balance improving funding while protecting member interests.
