The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or "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. The December 31, 2009 condensed consolidated balance sheet data was derived from our audited financial statements, but does not include all disclosures required by GAAP. In our opinion, all adjustments necessary for a fair statement 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 reporting.</td></tr></table> Note 2Basis of Presentation The significant accounting policies summarized in Note 1 to our audited consolidated financial statements false false false us-types:textBlockItemType textblock This element may be used to describe significant accounting policies of the reporting entity or contain references thereto; the basis of accounting used to prepare the financial statements; any exceptions to the comparability of prior year financial data with data shown for the most recent accounting period; and classifications in the current financial statements that may be different from classifications in the prior year's financial statements.
