Title 29 › CHAPTER 18 — EMPLOYEE RETIREMENT INCOME SECURITY PROGRAM › SUBCHAPTER III — PLAN TERMINATION INSURANCE › Subtitle E — Special Provisions for Multiemployer Plans › part 1 — employer withdrawals › § 1396
Tells how much an employer must pay when it stops contributing to certain pension plans that mostly cover people retired before January 1, 1976. If the employer withdraws before the plan is officially ended under the law, each year it must pay whichever is larger: the amount set by section 1399(c)(1)(C)(i), or the number of contribution base units it would have owed for the prior year times the contribution rate needed to meet the amortization schedule in section 1423(d)(3)(B)(ii) (ignoring any legal caps on that rate). An employer can’t be charged more than the total withdrawal liability calculated with interest. If an employer withdraws after December 31, 1983 and the union agrees to the plan’s ending, subsection (c) applies only if three conditions are met about past declines in contribution units, at least 50 percent of certain past liability being judged uncollectible, and contribution rates meeting the schedule after September 26, 1980. Applies to plans covered by section 404(c) of the tax code or their continuations, where most participants retired before January 1, 1976. Under subsection (c), the employer’s bill is its normal withdrawal amount multiplied by the larger of 90 percent or a fraction: the part of unfunded vested benefits from participants with 10 or more years of signatory service divided by total unfunded vested benefits. A "year of signatory service" is any year when the participant worked for an employer who was required (then or later) to make contributions.
