Background

Plaintiffs Richard Odom and William Drummond, vested participants in the Southern Company Pension Plan, alleged that the plan used unrealistic assumptions about life expectancy and interest rates to calculate their benefits. The plan used mortality tables from 1951 with significant setbacks and an assumed interest rate of five percent. Plaintiffs claimed these assumptions resulted in lower monthly payments and excessive charges for preretirement survivor benefits, violating ERISA’s actuarial equivalence and nonforfeiture rules.

The court’s reasoning

The court analyzed the term ‘actuarial equivalent’ as a term of art requiring reasonable assumptions grounded in professional norms. Citing Actuarial Standards of Practice and the definition of ‘present value’ in ERISA, the court concluded that projections must reflect anticipated events and realistic expectations. The court held that a plan converting a single-life annuity to a joint-and-survivor annuity must use assumptions a reasonable actuary would employ. Additionally, the court found that charges for preretirement survivor benefits are capped at a reasonable reflection of the plan’s increased costs.

What it means going forward

Pension plans can no longer rely on arbitrarily outdated mortality tables or interest rates to reduce benefit values. Plans must update their assumptions to reflect current life expectancy and market conditions to comply with ERISA.
