Executive summary The International Accounting Standards Board (IASB) has published ‘Plan Amendment, Curtailment or Settlement (Amendments to IAS 19)’. The amendments require companies to use updated actuarial assumptions to determine pension expenses following changes to a defined benefit pension plan.

Background IAS 19 ‘Employee Benefits’ requires a company to remeasure its net defined benefit liability or asset when an amendment to, or a curtailment or settlement of a defined benefit plan takes place. Prior to the publication of the February 2018 amendments however, IAS 19 did not require an entity to use updated assumptions to determine current service cost and net interest for the period after the change to the plan.
