Amendment Description The Amended Filing is a result of the restatement of our previously issued and audited consolidated financial statements and related disclosures for the years ended December 31, 2012, 2011, and 2010 included in our Original Filing. The impacts of the restatement on our Consolidated Balance Sheets, Consolidated Statements of Operations, Consolidated Statements of Comprehensive (Loss) Income, and Consolidated Statements of Cash Flows are detailed in Note 1A to the “Notes to the Consolidated Financial Statements.” The Amended Filing is also being made to revise unaudited quarterly financial information for 2012 and 2011. The impact of the restatement affects only the fourth quarter of the unaudited quarterly financial information for each of the years 2012 and 2011 (see “Note 17”).
