Title 29 › Chapter CHAPTER 18— - EMPLOYEE RETIREMENT INCOME SECURITY PROGRAM › Subchapter SUBCHAPTER I— - PROTECTION OF EMPLOYEE BENEFIT RIGHTS › Subtitle Subtitle B— - Regulatory Provisions › Part part 3— - funding › § 1085a
Require each covered multiemployer plan to keep a special "funding standard account" that tracks charges (what the plan must pay for the year) and credits (what it gets). Charges include the plan’s normal cost and a set of amortized amounts to pay down prior shortfalls: unfunded past service liability for plans in existence on January 1, 1974 is spread over 40 years, for plans that started after January 1, 1974 but before the first plan year after December 31, 2013 it is spread over 30 years, plan amendments’ added liability is spread over 15 years, experience losses over 5 years, and assumption changes over 10 years. Some other specific amounts are amortized over 5 or 20 years as described in the law. Credits include employer contributions, gains and reductions spread over the same time rules, waived deficiencies, and certain transfers from an alternative minimum funding standard account for plans that use a funding method requiring at least entry-age-normal contributions. The plan may combine or offset amortization items under Treasury rules. Interest is added to account balances at rates consistent with the plan’s cost rates, except certain amortizations must use at least 150 percent of the Federal mid-term rate. Valuations of assets and liabilities must use reasonable actuarial methods, count market value, and be done at least once a year. Require regular payments in four equal installments due April 15, July 15, October 15, and January 15; if a plan with funded current liability under 100 percent misses a full installment, interest on the unpaid amount is the greater of 175 percent of the Federal mid-term rate or the plan’s cost rate. If unpaid required payments and interest for plans with underpayments total more than $1,000,000, the Pension Benefit Guaranty Corporation can get a lien; the plan must notify PBGC within 10 days of a missed due date. The Treasury Secretary can allow up to a 10-year extra amortization period in special cases. If a plan’s funded percentage is under 80 percent at the start of a year, the plan must have the actuary certify that fact by day 90 of the plan year and the sponsor must file a written funding restoration plan within 180 days to reach 100 percent funded within the greater of 7 years or the shortest practicable time; while in restoration, benefit-increasing amendments are barred unless the sponsor pays the cost. Key terms: "accumulated funding deficiency" means charges exceed credits in the funding account (or, if smaller, in the alternative account); "funding standard account" and "alternative minimum funding standard account" are the two special ledgers plans must use; "funded percentage" compares asset value to current liability.
