Amendment Description This amendment to the Quarterly Report on Form 10-Q/A ("Amendment No. 1") is being filed in order to include disclosure regarding previously undisclosed out-of-period adjustments to the consolidated financial statements that were included in Part I, Items 1 And 2 of the original Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2012 previously filed on April 27, 2012 (the "Original Filing"). During the second quarter 2012, we identified an error in the consolidated financial statements for the year ended December 31, 2011 and the quarter ended March 31, 2012. The error was attributable to the misapplication of accounting guidance related to the recognition of a deferred tax asset resulting from an impairment of assets in the fourth quarter of 2011 that failed to consider a partial reversal of that asset that would result from a cancellation of related inter-company debt in the first quarter of 2012. During the first quarter of 2012, we identified an error that impacted the above referenced periods. The error was an over-accrual of incentive compensation cost. We have determined that the errors were not material in 2011 and are not material to our expected annual results for the year ending December 31, 2012. Accordingly, the cumulative change is reported as an out-of-period adjustment in the three months ended March 31, 2012 on our consolidated statement of operations. This Amendment No. 1 amends and restates only Part Items 1 And 2 of the Original Filing soley to reflect the restatement of consolidated financial statements and to add disclosure to Part I, Item 2 relating to such revision. The remaining items contained within this Amendment No. 1 consist of all other items originally contained in the Original Filing. These remaining items are not amended hereby, but are included for the convenience of the reader. Except for the foregoing amended information, This Amendment No. 1 continues to describe conditions as of the date of the Original Filing, and we have not updated the disclosures contained herein to reflect events that occurred at a later date. We are also updating the signature page and certifications of our Chief Executive and Financial Officers contained in Exhibits 31.1, 31.2, 32.1 and 32.2.
