Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments Operating Leases The Company leases its facilities and certain equipment under non-cancelable operating leases that expire at various dates through March 20, 2026. Certain leases require the Company to pay variable costs such as taxes, maintenance, and insurance and include renewal options and escalation clauses. Future minimum payments under the non-cancelable operating leases totaled $129.4 million as of June 30, 2016. Rent expense was $10.5 million and $19.6 million for the three and six months ended June 30, 2016, respectively, and $10.9 million and $22.4 million for the three and six months ended June 30, 2015, respectively. Data Center Lease Agreement On July 10, 2015, the Company entered into a data center lease agreement through March 2026 in which the Company has the option to extend the term of the lease for up to twenty years in increments of either five years or ten years, for approximately 63,000 square feet of space in the State of Washington. The total payment for the lease is expected to be approximately $118.1 million over the ten-year term. The lease agreement provides the Company with a tenant allowance of $6.0 million to be used for tenant leasehold improvements. Any unused tenant allowance may be applied as a credit to the rent payment. The space will be used, among other things, to consolidate certain of the Company's laboratory operations currently located in Sunnyvale, California. As the Company is subject to certain contractual obligations during the construction period, the Company was deemed the owner of the property during the construction period and capitalized construction in progress and recorded a corresponding long-term liability for build-to-suit lease agreements. As of December 31, 2015, the Company capitalized construction costs by recording a build-to-suit lease asset under construction in progress of $45.6 million, which is a component of property and equipment, net, and a corresponding build-to-suit financing liability, which is a component of other long-term liabilities, in the Condensed Consolidated Balance Sheets. During the six months ended June 30, 2016, the Company increased the build-to-suit asset and financing liability by $15.3 million for construction costs incurred. Upon the completion of construction in April 2016, the Company assessed whether these arrangements qualify for sales recognition under the sale-leaseback accounting guidance. The Company concluded that it had a certain form of continuing economic involvement in the facility, which precluded sale-leaseback accounting treatment. As a result, a total of $60.9 million of costs capitalized were placed in service and will be depreciated over the lease term. Purchase Commitments with Contract Manufacturers and Suppliers In order to reduce manufacturing lead times and in the interest of having access to adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $578.0 million as of June 30, 2016. The Company establishes a liability in connection with purchase commitments related to quantities in excess of its demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on the Company’s demand forecast or customer orders. As of June 30, 2016, the Company had accrued $19.7 million based on its estimate of such charges. Debt and Interest Payment on Debt As of June 30, 2016, the Company held long-term debt consisting of the Notes with a carrying value of $2,132.5 million. Of these Notes, $350.0 million will mature in 2019 and bears interest at a fixed rate of 3.125%, $300.0 million will mature in 2020 and bears interest at a fixed rate of 3.30%, $300.0 million will mature in 2021 and bears interest at a fixed rate of 4.60%, $500.0 million will mature in 2024 and bears interest at a fixed rate of 4.50%, $300.0 million will mature in 2025 and bears interest at a fixed rate of 4.35%, and $400.0 million will mature in 2041 and bears interest at a fixed rate of 5.95%. Interest on the Notes is payable semiannually. See Note 9, Debt and Financing, for further discussion of the Company's long-term debt. Other Contractual Obligations As of June 30, 2016, other contractual obligations primarily consisted of (1) $85.3 million in indemnity and employee-related obligations and service-related escrows, including those required in connection with certain asset purchases and acquisitions completed by the Company between 2005 and 2016; (2) $3.5 million in campus build-out obligations; and (3) $42.1 million of agreements that include firm and non-cancelable terms to transfer funds in the future for fixed or minimum amounts or quantities to be purchased at fixed or minimum prices. Tax Liabilities As of June 30, 2016, the Company had $199.8 million included in long-term income taxes payable in the Condensed Consolidated Balance Sheets for unrecognized tax positions. At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments related to this amount due to uncertainties in the timing of tax audit outcomes. Guarantees The Company enters into agreements with customers that contain indemnification provisions relating to potential situations where claims could be alleged that the Company’s products solely, or in combination with other third party products, infringe the intellectual property rights of a third-party. As of June 30, 2016, the Company recorded a $16.8 million liability for such indemnification obligations in other accrued liabilities in the Condensed Consolidated Balance Sheets. The Company also has financial guarantees consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, custom and duty guarantees, and standby letters of credit for certain lease facilities. As of June 30, 2016 and December 31, 2015, the Company had $6.4 million and $15.8 million, respectively, in financing arrangements, bank guarantees, and standby letters of credit related to these financial guarantees. Legal Proceedings Investigations The U.S. Securities and Exchange Commission ("SEC") and the U.S. Department of Justice ("DOJ") are conducting investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act ("FCPA"). The Company is cooperating with these agencies regarding these matters. The Company’s Audit Committee, with the assistance of independent advisors, has been investigating and conducting a thorough review of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, which the Company has implemented and continues to implement. The Company is unable to predict the duration, scope or outcome of the SEC and DOJ investigations, but believes that an adverse outcome is reasonably possible. However, the Company is not able to estimate a reasonable range of possible loss. The SEC and/or DOJ could take action against the Company or the Company could agree to settle. In such event, the Company could be required to pay substantial fines and sanctions and/or implement additional remedial measures; in addition, it may be determined that the Company violated the FCPA. Other Litigation In addition to the investigations discussed above, the Company is involved in other disputes, litigations, and legal proceedings. The Company intends to aggressively defend itself in these matters, and while there can be no assurances and the outcome of these matters is currently not determinable, the Company currently believes that none of these existing claims or proceedings are likely to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses. The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company has not recorded any accrual for loss contingencies associated with such legal proceedings or the investigations discussed above. However, the Company has accrued for unrecognized tax benefits in connection with certain tax-related proceedings as described in further detail in Note 13, Incomes Taxes.
