The formulas
- Interest = PBO x discount rate
- Expected return = market-related value x expected return
- Corridor = 10% x greater of PBO and market-related value
- Amortization = (net loss beyond corridor) / average remaining service
- Cost = service + interest - expected return + prior service cost + amortization
How it works
ASC 715-30-35-24 sets the minimum amortization of net gain or loss: the excess over 10 percent of the greater of the PBO or the market-related value of plan assets, divided by the average remaining service period of active participants. The tool uses opening balances and ignores contributions and benefit payments during the year.
ASU 2017-07 presents service cost with other compensation costs in operating expense and presents the other components outside income from operations. Only service cost is eligible for capitalization.

Common questions
Can faster amortization be used?
Yes, any systematic method that amortizes at least the minimum, applied consistently to gains and losses.
Is market-related value the same as fair value?
It may be fair value or a calculated value that recognizes changes over no more than five years.
What if nearly all participants are inactive?
Use the average remaining life expectancy of inactive participants instead of service period.
