- Definition

The after-tax amount of the change in the additional pension liability not yet recognized pursuant to FAS 87 par 37 and 38 as a net periodic pension cost. If the additional pension liability required to be recognized exceeds the unrecognized prior service costs, then the excess (which is the net loss not yet recognized as net periodic pension cost) is to be recorded as a reduction of other comprehensive income, before adjusting for tax effects. If in a subsequent measurement, the amount of minimum liability is eliminated or adjusted, this adjustment is offset against other comprehensive income in Accumulated Comprehensive Income. This line also includes changes in an entity's share of an equity investee's Increase or Decrease in additional pension liability not yet recognized as a net periodic pension cost. Eliminated upon adoption of FAS 158.
