💡 Accountant's Note

Withdrawal liability is the single most dangerous financial exposure from MEP participation — it can exceed the employer's entire market value in severely underfunded plans (Central States SE & SW Areas Pension Fund has been in crisis for decades with massive withdrawal liabilities). Under MEPPA (Multi-Employer Pension Plan Amendments Act of 1980), complete withdrawal (permanently ceasing covered operations or completely ceasing the obligation to contribute) triggers liability equal to the employer's proportionate share of the plan's UNFUNDED VESTED BENEFITS at the withdrawal date. Partial withdrawal (reducing covered employees below 70% of a 3-year average baseline) triggers a proportionate partial liability. Paid in installments over 20 years maximum (with interest). Recognized when the withdrawal is probable and estimable.

Practitioner & Systems Framework

💻 ERP Architecture

Before terminating any unionized operation or selling a union-represented business unit, model the withdrawal liability from each MEP. The plan actuary calculates the employer's allocable share using the plan's mass withdrawal rules (which vary by plan — some use proportionate shares of all employers' prior contributions). Partial withdrawal calculations are complex — the 70% test compares current covered employees to a rolling 3-year base period average.

⚠️ Audit Flags

Withdrawal liability is a contingent liability that must be assessed for probability at each reporting date. Asset sales, facility closures, and CBA expirations without renewal are withdrawal triggers. Auditors request letters from union pension fund actuaries confirming the withdrawal liability estimate. Even if the company has not formally withdrawn, a closure that is probable of occurring within 12 months requires ASC 450 contingency analysis.
