- 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. A cash flow hedge is a hedge of the exposure to variability in the cash flows of a recognized asset or liability or a forecasted transaction that is attributable to a particular risk. The change includes an entity's share of an equity investee's increase or decrease in deferred hedging gains or losses. While for technical reasons this element has no balance attribute, the default assumption is a credit balance consistent with its label.

Pre-tax gain (loss) adjustment to other comprehensive income resulting from the settlement or curtailment of the entity's defined benefit pension and other postretirement plans. A settlement is defined as a transaction that (a) is an irrevocable action, (b) relieves the employer or plan of a primary responsibility for a pension benefit obligation, and (c) eliminates significant risks related to the obligations and the assets used to effect the settlement. A curtailment is an event that significantly reduces the expected years of future service of present employees or eliminates for a significant number of employees the accrual of defined benefits for some or all of their future services.
