EMPLOYER (SPONSOR) ACCOUNTING FOR A DEFINED BENEFIT PENSION PLAN
The funded status of a defined benefit pension plan on the employer’s balance sheet mirrors the overfunded or
underfunded status on the books of the pension plan on each balance sheet date. Differences between pension
assets and pension liabilities relate to funding policies of the employer, investment performance, changes in
actuarial assumption, and changes in the pension benefit formula. Pension plans measure and report pension
assets at fair values and measure and report pension liabilities using a current market interest rate for
high-quality, fixed-income investments. Thus, the amounts reported on the balance sheet of the employer and of
the pension fund reflect value changes as they occur.
Under both U.S. GAAP and IFRS, the following formula calculates the Net Pension Expense (or Credit) for a
defined benefit pension plan,:
Interest Cost (the increase in the obligation because of the passage of time)
+ Service Cost (the increase in the obligation because of an additional year of employee service)
– Expected Return on Pension Investments
+/– Amortization of Performance and Actuarial Gains and Losses
+/– Amortization of Prior Service Cost
Including interest cost as a positive amount and the expected return on pension investments as a negative
amount illustrates the extent to which expected earnings from pension investments cover the increase in the
pension liability caused by the passage of time. If the expected return is large enough, the firm will report a
