Amount represents the entity's proportionate share of certain gains and (losses) recorded by its equity method investees in the period. These gains and (losses) are the result of material events or transactions that are abnormal or significantly different from typical activities or are not reasonably expected to recur in the foreseeable future; but not both, and therefore does not meet both criteria for classification as an extraordinary item. The entity has recorded its proportionate share of these items as a component of equity income (loss) - net.
