Pension plan amendment requires a named plan, population, date, and evidence owner. A plan amendment is an authorized change to benefit terms. Record approval, communication, effective date, affected participants, past-versus-future service effect, and the actuarial remeasurement.

Apply it

A July amendment adds $600,000 of benefits for past service. The supported amount increases PBO and enters prior service cost in OCI before later amortization.

Common mistake

Do not assume that a board discussion creates pension prior service cost. Recognition depends on executed plan terms, the effective date, affected participants, and an actuarial remeasurement. A draft term sheet does not meet that evidence test. That error would recognize an effect before enforceable terms and the affected population are established.

Keep the boundary clear

A board discussion is not an executed amendment. Accounting applies supplied legal and actuarial conclusions and keeps unresolved dates or populations open.

Authority

Read ASC 715-30-35-10 for pension amendments granting benefits for prior service.
