1. Basis of Presentation

In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of only normal, recurring adjustments, necessary for a fair presentation of results for such periods. The results for any interim period are not necessarily indicative of results for the full year. The preparation of financial statements for interim periods does not require all of the disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted. The December 31, 2012 financial position data included herein was derived from the audited consolidated financial statements included in the 2012 Form 10-K but does not include all disclosures required by U.S. GAAP. These consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K as filed with the SEC for the year ended December 31, 2012.
