[1] In the fourth quarter of 2011, certain out-of-period adjustments were recorded related to the partial release of the Company's income tax valuation allowance. The adjustments of approximately $61 million primarily related to the classification of a deferred tax item and resulted in the Company recognizing an additional income tax benefit. The Company should have recognized the income tax benefit for this amount in the third quarter of 2011 with the release of a portion of the Company's income tax valuation allowance. Correcting the error was not material to any of the related periods.
