Basis of Presentation and Summary of Significant Accounting Policies [Abstract]
Basis of Consolidation	*Basis of Consolidation* The interim condensed consolidated financial statements incorporate the financial statements of the Company and all of its subsidiaries. All significant intercompany balances and transactions have been eliminated on consolidation.
Unaudited Interim Financial Information	*Unaudited Interim Financial Information* The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. For further information, reference is made to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.
Use of Estimates	*Use of Estimates* The preparation of interim condensed consolidated financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Actual results could differ materially from these estimates. On an ongoing basis, the Company evaluates estimates, including those related to the accounts receivable and allowance for doubtful accounts, fair values of financial instruments, fair values of stock-based awards and income taxes, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Presentation of Comprehensive Income	According to Accounting Standards Update No. 2011-05 “Presentation of Comprehensive Income,” the Company is required to present the total comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company has elected to present the comprehensive income in a single continuous statement which contains two sections, net earnings and comprehensive income.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
