(together with its consolidated subsidiaries, "United") and, effective October 1, 2010, Continental Airlines, Inc. ("Continental"). As a consequence of the merger described in Note 2, "Merger and Related Matters," UAL Corporation changed its name to United Continental Holdings, Inc. We sometimes use the words "we," "our," "us," and the "Company" in this Form 10-Q for disclosures that relate to both UAL and United. This Quarterly Report on Form 10-Q is a combined report of UAL and United, and does not include Continental as the merger had not closed as of September 30, 2010. Therefore, these Combined Notes to Condensed Consolidated Financial Statements (the "Footnotes") apply to both UAL and United, unless otherwise noted. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL. Interim Financial Statements. The UAL and United unaudited condensed consolidated financial statements (the "Financial Statements") shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The Financial Statements include all adjustments, including normal recurring adjustments and other adjustments such as asset impairment charges, which are considered necessary for a fair presentation of the Company's financial position and results of operations. Certain prior year amounts have been reclassified to conform to the current year's presentation. These Financial Statements should be read together with the information included in the combined UAL Corporation and United Annual Report on Form 10-K for the year ended December 31, 2009 (the "2009 Annual Report"). Restricted Cash. Restricted cash primarily includes cash collateral associated with workers' compensation obligations, reserves for institutions that process credit card ticket sales and cash collateral received from fuel hedge counterparties. Airline industry practice includes classification of restricted cash flows as either investing cash flows or operating cash flows. Cash flows related to restricted cash activity are classified as investing activities because the Company considers restricted cash arising from these activities similar to an investment. UAL's cash inflows (outflows) associated with its restricted cash balances for the nine month periods ended September 30, 2010 and 2009 were $71 million and $(37) million, respectively. </div> (1) Basis of Presentation United Continental Holdings, Inc.
