Basis of Presentation and Recently Issued Accounting Pronouncements

Basis of Presentation

The significant accounting policies summarized in Note 2 to our audited consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, filed with the United States Securities and Exchange Commission, or "SEC," on March 4, 2013, or the "Form 10-K," have been followed in preparing the accompanying condensed consolidated financial statements.

The December 31, 2012 condensed consolidated balance sheet data was derived from our audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America, or "GAAP."

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and footnotes. Actual results could differ materially from those estimates.

In our opinion, all adjustments necessary for a fair presentation of the results of operations for the interim periods have been made. Results for interim periods are not necessarily indicative of results for a full year.

Certain prior period amounts have been reclassified to conform with current period presentation.
