Operations and Significant Accounting Policies   Basis of Presentation   The interim unaudited condensed consolidated financial statements of Thoratec Corporation (we, our, us, or the Company) have been prepared and presented in accordance with accounting principles generally accepted in the United States of America (GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC), without audit, and reflect all adjustments necessary (consisting only of normal recurring adjustments) to present fairly our financial position, results of operations and cash flows as of and for the periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with GAAP, have been condensed or omitted. The accompanying financial statements should be read in conjunction with our fiscal 2010 consolidated financial statements, and the accompanying notes thereto, filed with the SEC in our Annual Report on Form 10-K (the 2010 Annual Report). The operating results for any interim period are not necessarily indicative of the results that may be expected for any future period.   The preparation of our unaudited condensed consolidated financial statements necessarily requires the Companys management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities on the unaudited condensed consolidated balance sheet dates and the reported amounts of revenues and expenses for the periods presented.  The actual amounts could differ from those estimated amounts.   On April 25, 2010, our board of directors made a decision to sell our wholly-owned subsidiary, International Technidyne Corporation (ITC) and on November 4, 2010, we sold ITC to ITC Nexus Holding Company, Inc. (Nexus) for $55 million in cash pursuant to a Stock Purchase Agreement, dated as of November 4, 2010, by and between the Company and Nexus. As such, certain financial statement items have been reclassified to be presented as discontinued operations. These reclassifications had no impact on previously reported total net income.   Revenue Recognition and Product Warranty   We recognize revenue from product sales to customers and distributors when evidence of an arrangement exists, and title has passed (generally upon shipment) or services have been rendered, the selling price (including pricing discounts) have been fixed or have become determinable, collectability is reasonably assured and there are no further obligations to customers or distributors, as applicable.   The majority of our products are covered by up to a one-year limited manufacturers warranty. Estimated contractual warranty obligations are recorded when related sales are recognized and any additional amounts are recorded when such costs are probable, can be reasonably estimated and are included in Cost of product sales. The change in accrued warranty expense from continuing operations is summarized in the following table:   <table style="WIDTH: 100%; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="100%" border="0"> <tr style="HEIGHT: 0px"> <td style="PADDING-RIGHT: 0in;
