Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The unaudited condensed consolidated financial statements and accompanying notes of the Company reflect all adjustments (all of which are normal, recurring in nature and those discussed in these notes) that are, in the opinion of management, necessary for a fair presentation of the interim periods presented. All intercompany balances and transactions have been eliminated in consolidation. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending December 31, 2016. Certain information and note disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (the SEC). The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes for the fiscal year ended December 31, 2015 included in the Company’s fiscal 2015 Annual Report on Form 10-K.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported results of operations during the reporting period. The significant estimates made by management affect revenues, accounts receivable, allowance for doubtful accounts, inventory reserves, intangibles, goodwill, share-based compensation, deferred revenue, return reserves, provision for income taxes, uncertain tax positions, loss contingencies, sales tax liabilities and accrued liabilities. Management periodically evaluates such estimates, which are adjusted prospectively based upon such periodic evaluation. Actual results could differ from these estimates and such differences may be material to the accompanying condensed consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance is a result of a joint project with the International Accounting Standards Board (IASB) to clarify and converge the revenue recognition principles under U.S. GAAP and International Financial Reporting Standards (IFRS) and to develop guidance that would streamline and enhance revenue recognition requirements. In April 2015, the FASB proposed a one-year deferral of the effective date for the new revenue reporting standard for entities reporting under U.S. GAAP. In accordance with the deferral, ASU 2014-09 will be effective for fiscal 2018, including interim periods within that reporting period. The Company is currently evaluating the impact that the standard will have on its consolidated financial statements and related disclosures and has not selected a transition method. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which will require a lessee to recognize assets and liabilities with lease terms of more than twelve months. Both capital and operating leases will need to be recognized on the balance sheet. The standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that the standard will have on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This standard amends ASU 2014-09 to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The effective date and transition of this amendment is the same as the effective date and transition of ASU 2014-09. The Company is currently in the process of evaluating the impact of the adoption on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting (Topic 718), which simplifies the accounting for stock-based compensation related to the accounting for forfeitures, employer tax withholding, excess tax benefits related to awards and cash flow presentations. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is currently in the process of evaluating the impact of the adoption on its consolidated financial statements and related disclosures. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing (Topic 606), which amends the revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. The effective date and transition of this amendment is the same as the effective date and transition of ASU 2014-09. The Company is currently in the process of evaluating the impact of the adoption on its consolidated financial statements and related disclosures.
