Significant Accounting Policies

1. Significant Accounting Policies. The accompanying (a) condensed consolidated balance sheet as of December 31, 2013, which has been derived from our audited financial statements, and (b) the unaudited condensed consolidated financial statements, have been prepared in accordance with accounting principles and SEC rules applicable to interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements included in this report contain all adjustments (consisting only of normal recurring adjustments and accruals) necessary for a fair presentation of the Company’s consolidated financial position as of March 31, 2014 and the consolidated results of its operations and cash flows for the three months ended March 31, 2014 and 2013. The accounting policies followed by the Company are set forth in Note A to the Company’s financial statements in its Annual Report on Form 10-K for its fiscal year ended December 31, 2013 filed with the SEC on March 31, 2014 (the “2013 10-K”). The unaudited interim consolidated financial statements included in this report, and the notes that follow, should be read in conjunction with the consolidated financial statements and related notes included in our 2013 10-K.

The preparation of consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. On an ongoing basis, we evaluate our estimates, including those related to the accounts receivable and sales allowances, and useful lives of property and equipment, fair values of stock-based awards, income taxes, warranty liability and other contingent liabilities, among others. We base our estimates on historical experience and on various assumptions that are believed to be reasonable, the results of which form the basis for making judgments and estimates about the carrying values of assets and liabilities. However, such estimates and the assumptions on which they were based may later prove to have been incorrect due to unforeseen changes in market or economic conditions or the occurrence of unexpected events. As a result, the carrying values of our assets and our results of operations could differ in the future from the carrying values and results of operations that were based on our earlier estimates and assumptions. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” in Item 2 of Part I of this report.
