Title 29 › CHAPTER 18 — EMPLOYEE RETIREMENT INCOME SECURITY PROGRAM › SUBCHAPTER I — PROTECTION OF EMPLOYEE BENEFIT RIGHTS › Subtitle B — Regulatory Provisions › part 3 — funding › § 1085a
Requires each covered multiemployer pension plan to keep a special funding account that shows whether the plan has an accumulated funding deficiency. The deficiency is the amount by which charges to that account exceed credits, or if smaller, the same comparison using an alternative minimum account. Each year the account is charged with the plan’s normal cost plus amounts to pay off past shortfalls over fixed time periods: 40 years for plans in existence on January 1, 1974; 30 years for plans that started after that date but before the first plan year after December 31, 2013; 15 years for increases from plan changes; 5 years for experience losses; 10 years for changes in actuarial assumptions; plus certain other special amortizations of 5 or 20 years. The account is credited by employer contributions and by gains or reductions in liabilities amortized over the same schedules. Amortization items can be combined or offset under Treasury rules. Interest is added or subtracted at the plan’s interest rate, except certain amortization charges must use the higher of the plan rate or 150 percent of the Federal mid-term rate. Existing amortization schedules in effect before 2014 stay in place. Plans must value assets and liabilities using reasonable actuarial methods and follow rules for annual valuations, with special rules for valuation dates, mortality tables, and which years of service count for new participants. Employers’ contributions made within 8½ months after a plan year are treated as if paid on the last day of that year. The Treasury may extend amortization periods up to 10 years in tight cases. Plans that use an entry-age-like method may keep an alternative minimum account with its own charge and credit rules. If a plan’s funded current liability percentage was under 100 percent and required installments are missed, interest on the shortfall is the greater of 175 percent of the Federal mid-term rate or the plan rate, and missed payments can trigger quarterly payment rules (four installments due April 15, July 15, October 15, and January 15, each equal to 25 percent of the required annual payment). If unpaid amounts exceed $1,000,000 for an underfunded plan, the Pension Benefit Guaranty Corporation can get a lien on the employer’s property. A plan is in funding restoration status if its funded percentage is under 80 percent; sponsors then must suspend benefit-raising amendments, create a written restoration plan within 180 days, and get an annual actuary certification within 90 days. Current liability means all benefits owed, except benefits that depend on unpredictable events until those events occur; the interest rate for current liability is the statutory third-segment rate.
