The financial information included in this report is unaudited but, in our opinion, includes all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The December 31, 2009 condensed consolidated balance sheet data were derived from our 2009 audited consolidated financial statements, but do not include all disclosures required by GAAP. Certain previously reported amounts have been reclassified to conform to the current year presentation. The preparation of our condensed consolidated financial statements requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.</font></font></font></div> <div style="text-indent: 0pt; display: block;"> </div> <div style="text-align: justify; text-indent: 0pt; display: block;"><font style="display: inline; font-family: Times New Roman; font-size: 11pt;" class="_mt"><font style="font-family: Times New Roman; font-size: 11pt;" class="_mt"><font style="font-family: Times New Roman; font-size: 11pt;" class="_mt"><font style="font-family: Times New Roman; letter-spacing: 5pt; font-size: 11pt;" class="_mt">   </font> The financial data for the three-month and six-month periods ended June 30, 2010 and 2009 included herein have been subjected to a limited review by KPMG LLP, our independent registered public accounting firm.
