Measurement Date (Valuation Date)
Definition
The specific date as of which the plan's financial condition is assessed for purposes of calculating withdrawal liability. Under Section 1391, this is the last day of the plan year preceding the year in which the employer withdraws. All parties agree the objective financial data must be measured as of this date; the dispute is whether actuarial assumptions must also be selected by this date.
Examples
- •The measurement date in this case was December 31, 2017—the end of the plan year before the employers withdrew in 2018.
