What is the amortization period for pension actuarial gains and losses?

Amortization occurs over the average remaining service period of active employees expected to receive benefits, typically 10–20 years for most pension plans. For plans mostly composed of retirees and inactive participants, the average remaining life expectancy is used instead.

How does a large actuarial loss in AOCI affect future earnings?

A large actuarial loss (e.g., from declining discount rates) in AOCI will increase future pension expense as it is amortized out of the corridor. This creates a headwind to earnings for years after a rate decline, even after rates recover. Plan sponsors use LDI to mitigate this effect.
