Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated balance sheet as of June 30, 2011, the condensed consolidated statements of income for the three and six months ended June 30, 2011 and 2010, and the condensed consolidated statements of cash flows for the six months ended June 30, 2011 and 2010 have been prepared on the same basis as our audited consolidated financial statements and include all adjustments necessary for the fair presentation of our consolidated results of operations, financial position and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future period. The condensed consolidated balance sheet as of December 31, 2010 has been derived from our audited financial statements, which are included in our 2010 Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 15, 2011.

The significant accounting policies and certain financial information that are normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, but which are not required for interim reporting purposes, have been omitted. The unaudited condensed consolidated interim financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2010.
