Under the final regulations, insolvent plans that are receiving financial assistance or terminated via amendment, but expected to become insolvent, must only perform actuarial valuations once every five years if the plan provides nonforfeitable benefits of $50 million or less. Under prior law, valuations were required every three years and the nonforfeitable benefit threshold was $25 million. In the alternative, the plan may, within 180 days, submit their current SPD, most recent actuarial report and certain other information to allow the PBGC to complete the valuation. Additionally, plan sponsors of insolvent or terminated plans now must file information about their withdrawal liability payments and withdrawal of employers who have not yet been assessed withdrawal liability with the PBGC within 180 days of the earlier of the end of the plan year in which the plan terminates or becomes insolvent. This filing is due annually. For more information on multiemployer pension plans, visit Tax Facts Online.
