Financial Reporting and Analysis 6e Pensions and Postretirement Benefits
i. The higher the discount rate initially chosen for computing service cost, the
lower the reported service cost component of pension expense. Conversely,
the higher the expected rate of return used, the higher the deducted expected
return component of the pension expense.
ii. This reduction in service cost is partially offset by an increase in the interest cost
component of pension expense, which is due to the higher interest rate.
b. GAAP provides explicit criteria for estimating discount rates. This criteria
reduces (but does not eliminate it) managers’ ability to manipulate its pension
expense and its projected benefit obligation.
i. GAAP states that “assumed discount rates shall reflect the rates at which the
pension benefits could effectively be settled” (FASB ASC 715-30–35–43).
ii. To obtain this discount rate, firms can look to prevailing rates of return on high–
quality debt instruments with maturities that match expected payouts to retirees.
iii. Recent decline in rates coupled with low asset returns have led to significant
underfunding in both private and government pension plans.
2. Uncertainty also means that realizations will likely differ from expectations.
a. These deviations between actual and expected events would inject volatility in
periodic pension expense if recognized immediately.
b. Components 4 and 5 are designed to smooth these variances over future periods.
E. Components 4 and 5 are smoothing devices:
1. Component 4 (Recognized Gains or Losses):
a. In an uncertain environment, the actual return on pension plan assets can differ from
the expected return in any year.
b. Volatility in year-to-year pension expense can be avoided because firms can reduce
pension expense by the expected return on plan assets rather than by the actual
return.
c. This result is accomplished using a two-stage process:
i. First, firms select a target long-term rate of return that they expect to earn on
plan assets (rate of return assumption).
ii. Second, any difference between this expected return and the actual return that is
earned in a given year is recognized in other comprehensive income instead of
pension expense.
d. The difference between the expected and actual return in each year is recognized in
other comprehensive income instead of pension expense and called the unrecognized
gain or loss.
e. Since managers select the rate for computing the expected return on plan assets, it is
possible to lower pension expense in the short-run by using an expected asset return
rate that is higher than the discount rate.
f. If the gains and losses do not offset one another over time, the cumulative deferred
amounts continue to grow.
i. This cumulative gain or loss amount is amortized over current and future years
and recognized as a component of pension expense if it exceeds a certain maturity
threshold called a “corridor.”
ii. This threshold is defined as 10% of the larger of the following two numbers
measured at the beginning of the period:
1. The present value of pension obligations (PBO) based on assumed
future compensation levels (called the projected benefit obligations), or
2. The market–related value (MRV) of pension plan assets.
iii. If the 10% threshold is exceeded, the excess cumulative gain or loss is
amortized straight-line over the estimated remaining service period of active
employees.
1. The amortization of excess cumulative gains reduces pension expense.
