- Definition Net of tax effect change in accumulated gains and losses from derivative instruments designated and qualifying as the effective portion of cash flow hedges after taxes.

The change includes an entity's share of an equity investee's increase or decrease in deferred hedging gains or losses.

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.
