Expected long-term return rate has one role in the employer's benefit accounting. The expected long-term return rate is a supported assumption about returns over the life of the obligation. Apply it to the policy's asset base to compute expected return in periodic cost.

Apply it

A six-percent rate applied to a supported $15 million market-related asset base gives $900,000 expected return. The current year's $1.05 million actual return does not reset that calculation.

Common mistake

Do not assume that management can select the expected return rate to reach a desired pension cost. The rate must be a supportable long-term assumption for plan assets and current-year contributions. That error would allow a desired accounting result to replace evidence about the plan's asset strategy.

Keep the boundary clear

Accounting reviews consistency with asset allocation and documented expectations but does not select the rate or promise that the trust will earn it.

Authority

Read ASC 715-20-50-8 for the expected long-term return rate used in net benefit cost.
