Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. (“Equinix” or the “Company”) and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2015 has been derived from audited consolidated financial statements as of that date. The consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission (“SEC”), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”). For further information, refer to the Consolidated Financial Statements and Notes thereto included in Equinix’s Form 10-K as filed with the SEC on February 26, 2016. Results for the interim periods are not necessarily indicative of results for the entire fiscal year. Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of Telecity Group plc (“TelecityGroup”) from January 15, 2016, Bit-isle Inc. (“Bit-isle”) from November 2, 2015 and Nimbo Technologies Inc. (“Nimbo”) from January 14, 2015. All significant intercompany accounts and transactions have been eliminated in consolidation. Income Taxes The Company began operating as a real estate investment trust for federal income tax purposes ("REIT") effective January 1, 2015. In May 2015, the Company received a favorable response to a private letter ruling (“PLR”) it had requested from the U.S. Internal Revenue Service (“IRS”) in connection with the Company’s conversion to a REIT for federal income tax purposes. As a result, the Company may deduct the distributions made to its shareholders from taxable income generated by the Company and its qualified REIT subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the taxable income of the Company and its QRSs, resulting in no U.S. income tax due. However, the Company's taxable REIT subsidiaries (“TRSs”) will continue to be subject to income taxes on any taxable income generated by them. In addition, the foreign operations of the Company will continue to be subject to local income taxes regardless of whether the foreign operations are operated as a QRS or a TRS. The Company provides for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate is subject to change in the future due to various factors such as the operating performance of the Company, tax law changes and future business acquisitions. The Company’s effective tax rates were 61.7% and 9.2% for the six months ended June 30, 2016 and 2015, respectively. The increase in the effective tax rate for the six months in 2016 as compared to the same period in 2015 is primarily due to a much lower profit before tax for the period, attributable to the non-tax deductible costs related to the TelecityGroup acquisition and an increase in valuation allowance. Assets Held for Sale and Discontinued Operations Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale as set forth in the accounting standard for impairment or disposal of long-lived assets are reported at the lower of their carrying amounts or fair values less costs to sell. Assets are not depreciated or amortized while they are classified as held for sale. A component of a reporting entity or a group of components of a reporting entity that are disposed or meet the criteria to be classified as held for sale should be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The accounting guidance requires a business activity that, on acquisition, meets the criteria to be classified as held for sale be reported as a discontinued operation. For further information on the Company’s assets held for sale and discontinued operations, see Notes 4 and 5. Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In June 2016, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). This ASU simplifies several areas of the accounting for share-based payment award transactions, including ( a ) income tax consequences; ( b ) classification of awards as either equity or liabilities; and ( c ) classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815), Contingent Put and Call Options in Debt Instruments ("ASU 2016-06"). This ASU clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. This guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year in which the amendments are effective, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815), Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships ("ASU 2016-05"). This ASU clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This ASU may be applied prospectively or using a modified retrospective approach, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. ASU 2016-02 is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. While the Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements, the Company believes this standard will have a significant impact on its consolidated financial statements due, in part, to the substantial amount of operating leases it has. In January 2016, the FASB issued ASU 2016-01, Financial Instruments- Overall (Subtopic 825-10) ("ASU 2016-01"), which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income other than those accounted for under equity method of accounting or those that result in consolidation of the investees. The ASU also requires that an entity present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the ASU eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. ASU 2016-01 is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) Topic 606 and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016 and May 2016 within ASU 2015-04, ASU 2016-08, ASU 2016-10 and ASU 2016-12, respectively (ASU 2014-09, ASU 2015-04, ASU 2016-08, ASU 2016-10, ASU 2016-11 and ASU 2016-12 collectively, Topic 606). Topic 606 will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of Topic 606 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. Topic 606 requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. Topic 606, as amended, is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein (i.e., January 1, 2018, for a calendar year entity). Early application for public entities is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. Accounting Standards Adopted In September 2015, the FASB issued ASU 2015-16, Business Combinations ("ASU 2015-16"), to simplify accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects as a result of changes to provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company adopted ASU 2015-16 in the three months ended March 31, 2016. The adoption of ASU 2015-16 did not have a significant impact on the Company's consolidated financial statements. In May 2015, the FASB issued ASU 2015-07, Fair Value Measurement (“ASU 2015-07”), which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using the net asset value per share of the investment. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. A reporting entity should apply the amendment retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. The Company adopted ASU 2015-07 in the three months ended March 31, 2016. The adoption of ASU 2015-07 did not have a significant impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidations (“ASU 2015-02”). This ASU requires companies to adopt a new consolidation model, specifically: (1) the ASU modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (2) the ASU eliminates the presumption that a general partner should consolidate a limited partnership; (3) the ASU affects the consolidation analysis of reporting entities involved with VIEs and (4) the ASU provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted ASU 2015-02 in the three months ended March 31, 2016. The adoption of ASU 2015-02 did not have a significant impact on the Company's consolidated financial statements. In January 2015, the FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items (“ASU 2015-01”), to simplify the income statement presentation requirements by eliminating the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company adopted ASU 2015-01 in the three months ended March 31, 2016. The adoption of ASU 2015-01 did not have a significant impact on the Company's consolidated financial statements.

Acquisitions	Acquisitions TelecityGroup Acquisition On January 15, 2016, the Company completed the acquisition of the entire issued and to be issued share capital of TelecityGroup. TelecityGroup operates data center facilities in cities across Europe. The acquisition of TelecityGroup enhances the Company's existing data center portfolio by adding new IBX metro markets in Europe including Dublin, Helsinki, Istanbul, Manchester, Milan, Sofia, Stockholm and Warsaw. As a result of the transaction, TelecityGroup has become a wholly-owned subsidiary of Equinix. Under the terms of the acquisition, the Company acquired all outstanding shares of TelecityGroup and all vested equity awards of TelecityGroup at 572.5 pence in cash and 0.0336 new shares of Equinix common stock for a total purchase consideration of approximately £2,624,500,000 or approximately $3,743,587,000 . In addition, the Company assumed $1,299,000 of vested TelecityGroup's employee equity awards as part of consideration transferred. The Company incurred acquisition costs of approximately $14,370,000 and $50,555,000 during the three and six months ended June 30, 2016 related to the TelecityGroup acquisition. In connection with the TelecityGroup acquisition, the Company placed £322,851,000 or approximately $475,689,000 into a restricted cash account, which was included in the current portion of restricted cash in the condensed consolidated balance sheet as of December 31, 2015. The cash was released upon completion of the acquisition. Also, in connection with TelecityGroup acquisition, the Company entered into a bridge credit agreement with J.P. Morgan Chase Bank, N.A. (“JPMCB”) as the initial lender and as administrative agent for the lenders for a principal amount of £875,000,000 or approximately $1,289,000,000 at the exchange rate in effect on December 31, 2015 (the “Bridge Loan”). The Company did not make any borrowings under the Bridge Loan and the Bridge Loan was terminated on January 8, 2016. The Company has initially designated the legal entities acquired in the TelecityGroup acquisition as TRSs. Purchase Price Allocation Under the acquisition method of accounting, the assets acquired and liabilities assumed in a business combination shall be measured at fair value at the date of the acquisition. As of the date of this quarterly report, the Company has not completed the detailed valuation analysis to derive the fair value of the following items including, but not limited to, intangible assets, accounting for lease contracts; asset retirement obligations; favorable leasehold interests; assets and liabilities held for sale, deferred revenue; property, plant and equipment; accruals and taxes. Therefore, the allocation of the purchase price to acquired assets and liabilities is based on provisional estimates and is subject to continuing management analysis, with assistance of third party valuation advisers. As of the acquisition date, the preliminary allocation of the purchase price is as follows (in thousands): Cash and cash equivalents $ 73,368 Accounts receivable 24,042 Other current assets 34,583 Assets held for sale 892,169 Property, plant and equipment 1,055,667 Goodwill 2,264,789 Intangible assets 657,485 Deferred tax assets 1,198 Other assets 4,123 Total assets acquired 5,007,424 Accounts payable and accrued expenses (90,589 ) Accrued property, plant and equipment (3,634 ) Other current liabilities (27,259 ) Liabilities held for sale (156,169 ) Capital lease and other financing obligations (199,809 ) Mortgage and loans payable (592,304 ) Deferred tax liabilities (159,701 ) Other liabilities (33,073 ) Net assets acquired $ 3,744,886 The preliminary purchase price allocation above, as of the acquisition date, includes acquired assets and liabilities that were classified by the Company as held for sale (Note 4). The following table presents certain information on the acquired intangible assets (dollars in thousands): Intangible assets Fair value Estimated useful lives (years) Weighted-average estimated useful lives (years) Customer relationships $ 563,428 13.5 13.5 Trade names 72,033 1.5 1.5 Favorable leases 22,024 2.4 - 33.0 13.6 The fair value of customer relationships was estimated by applying an income approach. The fair value was determined by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The Company applied a weighted-average discount rate of approximately 8.5% , which reflected the nature of the assets as it relates to the estimated future operating cash flows. Other significant assumptions used to estimate the fair value of the customer relationships include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. The fair value of the TelecityGroup trade name was estimated using the relief of royalty approach. The Company applied a relief of royalty rate of 2.0% and a weighted-average discount rate of approximately 9.0% . The other acquired identifiable intangible assets were estimated by applying a relief of royalty or cost approach as appropriate. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements. The fair value of the property, plant and equipment was estimated by applying the income approach or cost approach. The income approach is used to estimate fair value based on the income stream, such as cash flows or earnings that an asset can be expected to generate over its useful live. There are two primary methods of applying the income approach to determine the fair value assets: the discounted cash flow method and the direct capitalization method. The key assumptions include the estimated earnings, discount rate and direct capitalization rate. The cost approach is to use the replacement or reproduction cost as an indicator of fair value. The premise of the cost approach is that a market participant would pay no more for an asset than the amount that the asset could be replaced or reproduced. The key assumptions of the cost approach include replacement cost new, physical deterioration, functional and economic obsolescence, economic useful life, remaining useful life, age and effective age. The Company determined the fair value of the loans payable assumed in the TelecityGroup acquisition by estimating TelecityGroup’s debt rating and reviewing market data with a similar debt rating and other characteristics of the debt, including the maturity date and security type. On January 15, 2016, the Company prepaid and terminated these loans payable. In conjunction with the repayment of the loans payable, the Company incurred an insignificant amount of pre-payment penalties and interest rate swap termination costs, which were recorded as interest expense in the condensed consolidated statement of operations. Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The goodwill is attributable to the workforce of the acquired business and the significant synergies expected to arise after the acquisition. The goodwill is not expected to be deductible for local tax purposes. Goodwill will not be amortized and will be tested for impairment at least annually. Goodwill recorded as a result of the TelecityGroup acquisition, except for the goodwill associated with asset held for sale, is attributable to the Company’s EMEA region. For the three months ended June 30, 2016, the Company's results of continuing operations include TelecityGroup revenues of $107,246,000 and net loss from continuing operations of $35,858,000 . For the six months ended June 30, 2016, the Company's results of continuing operations include TelecityGroup revenues of $191,685,000 and net loss from continuing operations of $38,679,000 for the period January 15, 2016 through June 30, 2016. Bit-isle Acquisition On November 2, 2015, the Company completed a cash tender offer for approximately 97% of the equity instruments, including stock options, of Tokyo-based Bit-isle. The Company acquired the remaining outstanding equity instruments of Bit-isle in December 2015. The offer price was JPY 922 per share, in an all cash transaction totaling approximately $275,367,000 . The Company acquired Bit-isle to expand additional data centers in Japan for customer's future expansion needs. On September 30, 2015, the Company entered into a term loan agreement (the “Bridge Term Loan Agreement”) with the Bank of Tokyo-Mitsubishi UFJ, Ltd. (“BTMU”). Pursuant to the Bridge Term Loan Agreement, BTMU committed to provide a senior bridge loan facility (the “Bridge Term Loan”) in the amount of up to ¥47,500,000,000 , or approximately $459,800,000 in U.S. dollars at the exchange rate in effect on June 30, 2016. Proceeds from the Bridge Term Loan were to be used exclusively for the acquisition of Bit-isle, the repayment of Bit-isle’s existing debt and transaction costs incurred in connection with the closing of the Bridge Term Loan and the acquisition of Bit-isle. The Company included Bit-isle’s results of operations from November 2, 2015 and the estimated fair value of assets acquired and liabilities assumed in its consolidated balance sheets beginning November 2, 2015. The Company has initially designated the legal entities acquired in the Bit-isle acquisition as TRSs. Purchase Price Allocation Under the acquisition method of accounting, the total purchase price was allocated to Bit-isle’s net tangible and intangible assets based upon their fair value as of the Bit-isle acquisition date. Under the accounting guidance, the Company can adjust the fair value of acquired assets and liabilities assumed in the measurement period, as it obtains new information regarding the facts and circumstances that existed at the acquisition date. Based upon the purchase price and the valuation of Bit-isle, the purchase price allocation was as follows (in thousands): Cash and cash equivalents $ 33,198 Accounts receivable 7,359 Other current assets 51,038 Long-term investments 3,806 Property, plant and equipment 308,985 Goodwill 95,444 Intangible assets 111,374 Other assets 22,981 Total assets acquired 634,185 Accounts payable and accrued expenses (15,028 ) Accrued property, plant and equipment (465 ) Capital lease and other financing obligations (108,833 ) Mortgage and loans payable (190,227 ) Other current liabilities (8,689 ) Deferred tax liabilities (32,192 ) Other liabilities (3,384 ) Net assets acquired $ 275,367 The following table presents certain information on the acquired identifiable intangible assets (dollars in thousands): Intangible assets Fair value Estimated useful lives (years) Weighted-average estimated useful lives (years) Customer relationships $ 105,434 13 13 Trade name 3,455 2 2 Favorable solar contracts 2,410 18 18 Other intangible assets 75 0.25 0.25 The fair value of customer relationships was estimated by applying an income approach. The fair value was determined by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The Company applied a weighted-average discount rate of approximately 11.0% , which reflected the nature of the assets as it relates to the estimated future operating cash flows. Other significant assumptions used to estimate the fair value of the customer relationships include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. The fair value of the Bit-isle trade name was estimated using the relief of royalty approach. The Company applied a relief of royalty rate of 2.0% and a weighted-average discount rate of approximately 12.0% . The other acquired identifiable intangible assets were estimated by applying an income or cost approach as appropriate. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements. The fair value of the property, plant and equipment was estimated by applying the income approach or cost approach. The income approach is used to estimate fair value based on the income stream, such as cash flows or earnings that an asset can be expected to generate over its useful live. There are two primary methods of applying the income approach to determine the fair value assets: the discounted cash flow method and the direct capitalization method. The key assumptions include the estimated earnings, discount rate and direct capitalization rate. The cost approach is to use the replacement or reproduction cost as an indicator of fair value.

The key assumptions of the cost approach include replacement cost new, physical deterioration, functional and economic obsolescence, economic useful life, remaining useful life, age and effective age. The Company determined the fair value of the loans payable assumed in the Bit-isle Acquisition by estimating Bit-isle’s debt rating and reviewed market data with a similar debt rating and other characteristics of the debt, including the maturity date and security type. During the year ended December 31, 2015, the Company prepaid and terminated the majority of these loans payable. In conjunction with the repayment of the loans payable, the Company incurred an insignificant amount of pre-payment penalties and interest rate swap termination costs, which were recorded as interest expense in the consolidated statement of operations for the year ended December 31, 2015. Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The goodwill is attributable to the workforce of the acquired business and the significant synergies expected to arise after the acquisition. The goodwill is not expected to be deductible for local tax purposes. Goodwill will not be amortized and will be tested for impairment at least annually. Goodwill recorded as a result of the Bit-isle acquisition is attributable to the Company’s Asia-Pacific region. For the three and six months ended June 30, 2016, the Company's results of continuing operations include Bit-isle revenues of $37,294,000 and $71,498,000 and Bit-isle net losses of $3,532,000 and $7,745,000 . Nimbo Acquisition On January 14, 2015, the Company acquired all of the issued and outstanding share capital of Nimbo, a company which specializes in migrating business applications to the cloud with extensive experience moving legacy applications into a hybrid cloud architecture, and connecting legacy data centers to the cloud, for a cash payment of $10,000,000 and a contingent earn-out arrangement to be paid over two years (the “Nimbo Acquisition”). Subsequent to the acquisition, Nimbo adopted the name Equinix Professional Services for Cloud. The Nimbo Acquisition was accounted for using the acquisition method. As a result of the Nimbo Acquisition, the Company recorded goodwill of $17,192,000 , which represents the excess of the total purchase price over the fair value of the assets acquired and liabilities assumed. The Company recorded the contingent earn-out arrangement at its estimated fair value. The results of operations for Nimbo are not significant to the Company; therefore, the Company does not present its purchase price allocation or pro forma combined results of operations. In addition, any prospective changes in the Company’s earn-out estimates are not expected to have a material effect on the Company’s consolidated statement of operations. Unaudited Pro Forma Combined Consolidated Financial Information The following unaudited pro forma combined consolidated financial information has been prepared by the Company using the acquisition method of accounting to give effect to the TelecityGroup and Bit-isle acquisitions as though the acquisitions occurred on January 1, 2015. The Company completed the TelecityGroup acquisition on January 15, 2016. The operating results of TelecityGroup were included in the condensed consolidated statement of operations for the three months ended June 30, 2016. TelecityGroup's operating results for the period January 15, 2016 through June 30, 2016 were included in the condensed consolidated statement of operations for the six months ended June 30, 2016. The pro forma effect for the period January 1 through January 14, 2016 was insignificant. The unaudited pro forma combined consolidated financial information reflects certain adjustments, such as additional depreciation, amortization and interest expense on assets and liabilities acquired. The unaudited pro forma combined consolidated financial information is presented for illustrative purposes only and is not necessarily indicative of the results of operations that would have actually been reported had the acquisitions occurred on the above dates, nor is it necessarily indicative of the future results of operations of the combined company. The following table sets forth the unaudited pro forma consolidated combined results of operations for the three and six months ended June 30, 2015 (in thousands): Three months ended June 30, Six months ended June 30, 2015 2015 Revenues $ 796,850 $ 1,570,851 Net income from continuing operations 40,047 91,769 Basic EPS 0.63 1.44 Diluted EPS 0.62 1.43

Discontinued Operations and Disposal Groups [Abstract]
Assets Held for Sale	Assets Held for Sale During the fourth quarter of 2015, the Company entered into an agreement to sell a parcel of land in San Jose, California and reported the San Jose land parcel as an asset held for sale in the accompanying consolidated balance sheet as of December 31, 2015. The sale was completed in February 2016. In order to obtain the approval of the European Commission for the acquisition of TelecityGroup, the Company and TelecityGroup agreed to divest certain data centers, including the Company’s LD2 data center and certain data centers of TelecityGroup in the United Kingdom, Netherlands and Germany. The assets and liabilities of LD2, which were included within the EMEA operating segment, were classified as held for sale in the fourth quarter of 2015 and, therefore, the corresponding depreciation and amortization expense was ceased at that time. This divestiture was not presented as discontinued operations in the consolidated statements of operations, because it did not represent a strategic shift in the Company's business, as the Company continued operating similar businesses after the acquisition. During the three months ended June 30, 2016 and 2015, LD2 generated revenue of $2,950,000 and $4,746,000 , respectively. Net income generated by LD2 during the three months ended June 30, 2016 was insignificant. Net income generated by LD2 during the three months ended June 30, 2015 was $2,006,000 . During the six months ended June 30, 2016 and 2015, LD2 generated revenue of $6,116,000 and $9,429,000 , respectively. Net income generated by LD2 during the six months ended June 30, 2016 and 2015 was $2,327,000 and $3,880,000 , respectively. The acquisition of TelecityGroup closed on January 15, 2016. Accordingly, the assets and liabilities of the TelecityGroup data centers that were divested were included in assets and liabilities held for sale in the condensed consolidated balance sheet as of June 30, 2016. The results of operations for the TelecityGroup data centers that were divested were classified as discontinued operations from January 15, 2016, the date the acquisition closed, through June 30, 2016. This divestiture transaction closed on July 5, 2016 (see Note 13). In June 2016, the Company approved the divestiture of the solar power assets of Bit-isle. The assets and liabilities of the solar power assets that will be divested were included in assets and liabilities held for sale in the condensed consolidated balance sheet as of June 30, 2016. During the three and six months ended June 30, 2016, the revenues and net income generated from solar power assets were insignificant. When an asset is classified as held for sale, the asset's book value is evaluated and adjusted to the lower of its carrying amount or fair value less cost to sell. The determination of fair value for assets is dependent upon, among other factors, the potential sales transaction, composition of assets in the disposal group, the comparability of the disposal group to market transactions and negotiations with third party purchasers, etc. Such factors impact the range of potential fair values and the selection of the best estimates. As of June 30, 2016 and December 31, 2015, the Company determined that assets held for sale had not been impaired. The following table summarizes assets and liabilities that were classified in assets and liabilities held for sale as of June 30, 2016 and December 31, 2015 (in thousands): June 30, December 31, Cash $ 25,111 $ — Accounts receivable 15,470 2,222 Other current assets 78,013 408 Property, plant and equipment 238,742 23,533 Goodwill 461,558 5,000 Intangible assets 199,062 784 Other assets 6,710 1,310 Total assets held for sale 1,024,666 $ 33,257 Accounts payable, accrued expenses and estimated costs to sell $ (46,355 ) $ (654 ) Accrued property, plant and equipment (13,151 ) (816 ) Current portion of capital lease and other financing obligation (36,835 ) — Other current liabilities (27,167 ) (435 ) Capital lease and other financing obligations, less current portion (18,561 ) — Other liabilities (10,055 ) (1,630 ) Total liabilities held for sale $ (152,124 ) $ (3,535 ) Discontinued Operations In order to obtain the approval of the European Commission for the acquisition of TelecityGroup, the Company and TelecityGroup agreed to divest certain data centers of TelecityGroup in the United Kingdom, Netherlands and Germany. Accounting guidance requires a business activity that, on acquisition, meets the criteria to be classified as held for sale be reported as a discontinued operation. Accordingly, the results of operations for these data centers that were divested have been reported as net income from discontinued operations, net of tax, from January 15, 2016, the date of the acquisition, through June 30, 2016 in the Company's condensed consolidated statement of operations. This divestiture transaction closed on July 5, 2016 (see Note 13). The following table presents the financial results of the discontinued operations: Three months ended Six months ended Revenues $ 30,401 $ 50,982 Costs and operating expenses: Cost of revenues 13,490 25,100 Sales and marketing 979 1,196 General and administrative 6,920 7,303 Total costs and operating expenses 21,389 33,599 Income from operations of discontinued operations 9,012 17,383 Interest and other, net (708 ) (1,177 ) Income from discontinued operations before income taxes 8,304 16,206 Income tax expense (2,895 ) (4,581 ) Income from discontinued operations, net of income taxes $ 5,409 $ 11,625 Net cash used in operating activities for discontinued operations was $2,955,000 and net cash used in investing activities for discontinued operations was $35,701,000 for the period ended June 30, 2016. No gain or loss on the disposition of the assets and liabilities of these data centers has been recognized in the condensed consolidated financial statements.

Derivatives and Hedging Activit

Derivatives and Hedging Activities	6 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Derivatives Designated as Hedging Instruments Net Investment Hedges. The Company is exposed to the impact of foreign exchange rate fluctuations in investments in its wholly-owned foreign subsidiaries that are denominated in currencies other than the U.S. dollar. In order to mitigate the volatility in foreign currency exchange rates, the Company has entered into various foreign currency loans which are designated as hedges against the Company's net investment in foreign subsidiaries. In April 2015, the Company entered into a foreign currency term loan ("Term Loan A") and designated 100% of the Term Loan A to hedge its net investments in its wholly-owned foreign subsidiaries that are denominated in the same foreign currencies as the term loan. In December 2015, the Company terminated hedging its net investment in subsidiaries that are denominated in Swiss Francs. In January 2016, the Company borrowed the full amount of the $250,000,000 and £300,000,000 seven year term loan commitments made available to it under the second amendment to the Company's Senior Credit Facility ("Term Loan B"). The Company designated the portion of Term Loan B that is denominated in the British pound to hedge the net investments in its wholly-owned foreign subsidiaries. In March 2016, the Company began using foreign exchange forward contracts to hedge against the effect of foreign exchange rate fluctuations on a portion of its net investment in the EMEA operations. The total principal amount of foreign currency loans outstanding as of June 30, 2016 and December 31, 2015, which were designated as net investment hedges, was $793,264,000 and $411,881,000 , respectively. For a net investment hedge, most changes in the fair value of the hedging instrument designated as a net investment hedge, except the ineffective portion, are recorded as a component of other comprehensive income in the condensed consolidated balance sheet. The Company recorded net foreign exchange gains of $55,196,000 and $38,884,000 in other comprehensive income (loss) for the three and six months ended June 30, 2016 and foreign exchange losses of $10,389,000 in other comprehensive income (loss) for the three and six months ended June 30, 2015. The Company recorded no ineffectiveness from its net investment hedges for the three and six months ended June 30, 2016 and 2015. Cash Flow Hedges. The Company hedges its exposure to foreign currency exchange rate fluctuations for forecasted revenues and expenses in its EMEA region in order to help manage the Company’s exposure to foreign currency exchange rate fluctuations between the U.S. dollar and the British Pound, Euro and Swiss Franc. The foreign currency forward and option contracts that the Company uses to hedge this exposure are designated as cash flow hedges under the accounting standard for derivatives and hedging. The Company also uses purchased collar options to manage a portion of its exposure to foreign currency exchange rate fluctuations, where the Company writes a foreign currency call option and purchases a foreign currency put option. When two or more derivative instruments in combination are jointly designated as a cash flow hedging instrument, they are treated as a single instrument. Effective January 1, 2015, the Company entered into intercompany hedging instruments (“intercompany derivatives”) with a wholly-owned subsidiary of the Company and simultaneously entered into derivative contracts with unrelated parties to hedge certain forecasted revenues and expenses denominated in currencies other than the U.S. dollar.

Derivatives Not Designated as Hedging Instruments Embedded Derivatives . The Company is deemed to have foreign currency forward contracts embedded in certain of the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved. These embedded derivatives are separated from their host contracts and carried on the Company’s balance sheet at their fair value. The majority of these embedded derivatives arise as a result of the Company’s foreign subsidiaries pricing their customer contracts in the U.S. dollar. Gains and losses on these embedded derivatives are included within revenues in the Company’s condensed consolidated statements of operations. During the three months ended June 30, 2016, gains (losses) associated with these embedded derivatives were not significant.

During the six months ended June 30, 2015, gains (losses) associated with these embedded derivatives were not significant. Economic Hedges of Embedded Derivatives. The Company uses foreign currency forward contracts to manage the foreign exchange risk associated with the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved (“economic hedges of embedded derivatives”). Foreign currency forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. Gains and losses on these contracts are included in revenues along with gains and losses of the related embedded derivatives. The Company entered into various economic hedges of embedded derivatives during the three and six months ended June 30, 2016 and 2015 . During the three months ended June 30, 2016, the gains (losses) associated with these contracts were not significant. During the six months ended June 30, 2016, the gains associated with these contracts were $5,578,000 . During the three and six months ended June 30, 2015, the gains (losses) from these contracts were not significant. Foreign Currency Forward and Option Contracts. The Company also uses foreign currency forward and option contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities. As a result of foreign currency fluctuations, the U.S. dollar equivalent values of its foreign currency-denominated assets and liabilities change. Gains and losses on these contracts are included in other income (expense), net, along with foreign currency gains and losses of the related foreign currency-denominated assets and liabilities associated with these foreign currency forward and option contracts. The Company entered into various foreign currency forward and option contracts during the three and six months ended June 30, 2016 and 2015. During the three and six months ended June 30, 2016 , the Company recognized net gains of $49,072,000 and $41,480,000 , respectively, associated with these contracts.

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss, net of tax, are as follows (in thousands): Balance as of Net Change Balance as of Foreign currency translation adjustment (“CTA”) loss $ (523,709 ) $ (182,462 ) $ (706,171 ) Unrealized gain on cash flow hedges 11,153 7,942 19,095 Unrealized gain (loss) on available-for-sale securities (139 ) 895 756 Net investment hedge CTA gain 4,484 38,884 43,368 Net actuarial gain (loss) on defined benefit plans (848 ) 14 (834 ) $ (509,059 ) $ (134,727 ) $ (643,786 ) Changes in foreign currency exchange rates can have a significant impact to the Company’s consolidated balance sheets (as evidenced above in the Company’s foreign currency translation gain or loss), as well as its consolidated results of operations, as amounts in foreign currencies generally translate into more U.S. dollars when the U.S. dollar weakens or fewer U.S. dollars when the U.S. dollar strengthens. As of June 30, 2016 , the U.S. dollar was generally stronger relative to certain of the currencies of the foreign countries in which the Company operates. This overall strengthening of the U.S. dollar had an overall unfavorable impact on the Company’s consolidated financial position because the foreign denominations translated into fewer U.S. dollars as evidenced by an increase in foreign currency translation loss for the six months ended June 30, 2016 as reflected in the above table. In future periods, the volatility of the U.S. dollar as compared to the other currencies in which the Company operates could have a significant impact on its consolidated financial position and results of operations including the amount of revenue that the Company reports in future periods. Dividends On February 18, 2016 , the Company declared a quarterly cash dividend of $1.75 per share, with a record date of March 9, 2016 and a payment date of March 23, 2016 . The Company paid a total of $121,494,000 on March 23, 2016 for the first quarter cash dividend. In addition, the Company accrued an additional $1,366,000 in dividends payable for the restricted stock units that have not yet vested. On May 4, 2016, the Company declared a quarterly cash dividend of $1.75 per share, with a record date of May 25, 2016 and a payment date of June 15, 2016. The Company paid a total of $121,530,000 on June 15, 2016 for the second quarter cash dividend. In addition, the Company accrued an additional $2,053,000 in dividends payable for restricted stock units that have not yet vested. Stock-Based Compensation In the first half of 2016, the Compensation Committee and the Stock Award Committee of the Company’s Board of Directors approved the issuance of an aggregate of 530,068 shares of restricted stock units to certain employees, including executive officers, pursuant to the 2000 Equity Incentive Plan, as part of the Company’s annual refresh program. These equity awards are subject to vesting provisions and have a weighted-average grant date fair value of $290.89 and a weighted-average requisite service period of 3.47 years. The valuation of restricted stock units with only a service condition or a service and performance condition requires no significant assumptions as the fair value for these types of equity awards is based solely on the fair value of the Company’s stock price on the date of grant. The Company used revenue and adjusted funds from operations (“AFFO”) as the performance measurements in the restricted stock units with both service and performance conditions that were granted in February 2016 and 2015, whereby revenue and adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”) were used as the performance measurements in prior years’ grants. The Company uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition. There were no significant changes in the assumptions used to determine the fair value of restricted stock units with a service and market condition that were granted in 2016 compared to the prior year.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On July 5, 2016, the Company completed the sale of eight data centers and related assets in its European business to Digital Realty Trust, Inc. ("Digital Realty") for approximately €304,564,000 and £376,171,000 , or approximately $827,185,000 at the exchange rate in effect on July 5, 2016. On August 1, 2016, the Company purchased Digital Realty’s operating business, including its real estate and facility, in St. Denis, Paris, where the Company has an established presence with two IBX data centers, for approximately €189,645,000 or $211,700,000 at the exchange rate in effect on August 1, 2016. The acquisition of these two data centers will be accounted using the acquisition method of accounting in accordance with the accounting standard for business combinations. The preliminary purchase price allocation for acquisition is not currently available as the appraisals necessary to assess fair values of assets acquired and liabilities assumed are not yet complete. On August 3, 2016, the Company declared a quarterly cash dividend of $1.75 per share, which is payable on September 14, 2016 to the Company’s common stockholders of record as of the close of business on August 24, 2016.

Basis of Presentation and Sig19

Basis of Presentation and Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2016
Accounting Policies [Abstract]
Basis of presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. (“Equinix” or the “Company”) and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2015 has been derived from audited consolidated financial statements as of that date. The consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission (“SEC”), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”). For further information, refer to the Consolidated Financial Statements and Notes thereto included in Equinix’s Form 10-K as filed with the SEC on February 26, 2016. Results for the interim periods are not necessarily indicative of results for the entire fiscal year.
Consolidation	Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of Telecity Group plc (“TelecityGroup”) from January 15, 2016, Bit-isle Inc. (“Bit-isle”) from November 2, 2015 and Nimbo Technologies Inc. (“Nimbo”) from January 14, 2015. All significant intercompany accounts and transactions have been eliminated in consolidation.
Income taxes	Income Taxes The Company began operating as a real estate investment trust for federal income tax purposes ("REIT") effective January 1, 2015. In May 2015, the Company received a favorable response to a private letter ruling (“PLR”) it had requested from the U.S. Internal Revenue Service (“IRS”) in connection with the Company’s conversion to a REIT for federal income tax purposes. As a result, the Company may deduct the distributions made to its shareholders from taxable income generated by the Company and its qualified REIT subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the taxable income of the Company and its QRSs, resulting in no U.S. income tax due. However, the Company's taxable REIT subsidiaries (“TRSs”) will continue to be subject to income taxes on any taxable income generated by them. In addition, the foreign operations of the Company will continue to be subject to local income taxes regardless of whether the foreign operations are operated as a QRS or a TRS. The Company provides for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate is subject to change in the future due to various factors such as the operating performance of the Company, tax law changes and future business acquisitions.
Assets held for sale and discontinued operations	Assets Held for Sale and Discontinued Operations Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale as set forth in the accounting standard for impairment or disposal of long-lived assets are reported at the lower of their carrying amounts or fair values less costs to sell. Assets are not depreciated or amortized while they are classified as held for sale. A component of a reporting entity or a group of components of a reporting entity that are disposed or meet the criteria to be classified as held for sale should be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The accounting guidance requires a business activity that, on acquisition, meets the criteria to be classified as held for sale be reported as a discontinued operation.
Recent accounting pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In June 2016, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). This ASU simplifies several areas of the accounting for share-based payment award transactions, including ( a ) income tax consequences; ( b ) classification of awards as either equity or liabilities; and ( c ) classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815), Contingent Put and Call Options in Debt Instruments ("ASU 2016-06"). This ASU clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. This guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year in which the amendments are effective, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815), Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships ("ASU 2016-05"). This ASU clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This ASU may be applied prospectively or using a modified retrospective approach, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. ASU 2016-02 is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. While the Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements, the Company believes this standard will have a significant impact on its consolidated financial statements due, in part, to the substantial amount of operating leases it has. In January 2016, the FASB issued ASU 2016-01, Financial Instruments- Overall (Subtopic 825-10) ("ASU 2016-01"), which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income other than those accounted for under equity method of accounting or those that result in consolidation of the investees. The ASU also requires that an entity present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the ASU eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. ASU 2016-01 is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) Topic 606 and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016 and May 2016 within ASU 2015-04, ASU 2016-08, ASU 2016-10 and ASU 2016-12, respectively (ASU 2014-09, ASU 2015-04, ASU 2016-08, ASU 2016-10, ASU 2016-11 and ASU 2016-12 collectively, Topic 606). Topic 606 will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of Topic 606 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. Topic 606 requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. Topic 606, as amended, is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein (i.e., January 1, 2018, for a calendar year entity). Early application for public entities is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. Accounting Standards Adopted In September 2015, the FASB issued ASU 2015-16, Business Combinations ("ASU 2015-16"), to simplify accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects as a result of changes to provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company adopted ASU 2015-16 in the three months ended March 31, 2016. The adoption of ASU 2015-16 did not have a significant impact on the Company's consolidated financial statements. In May 2015, the FASB issued ASU 2015-07, Fair Value Measurement (“ASU 2015-07”), which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using the net asset value per share of the investment. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. A reporting entity should apply the amendment retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. The Company adopted ASU 2015-07 in the three months ended March 31, 2016. The adoption of ASU 2015-07 did not have a significant impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidations (“ASU 2015-02”). This ASU requires companies to adopt a new consolidation model, specifically: (1) the ASU modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (2) the ASU eliminates the presumption that a general partner should consolidate a limited partnership; (3) the ASU affects the consolidation analysis of reporting entities involved with VIEs and (4) the ASU provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted ASU 2015-02 in the three months ended March 31, 2016. The adoption of ASU 2015-02 did not have a significant impact on the Company's consolidated financial statements. In January 2015, the FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items (“ASU 2015-01”), to simplify the income statement presentation requirements by eliminating the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company adopted ASU 2015-01 in the three months ended March 31, 2016. The adoption of ASU 2015-01 did not have a significant impact on the Company's consolidated financial statements.
Derivatives, methods of accounting, hedging derivatives	Cash Flow Hedges. The Company hedges its exposure to foreign currency exchange rate fluctuations for forecasted revenues and expenses in its EMEA region in order to help manage the Company’s exposure to foreign currency exchange rate fluctuations between the U.S. dollar and the British Pound, Euro and Swiss Franc. The foreign currency forward and option contracts that the Company uses to hedge this exposure are designated as cash flow hedges under the accounting standard for derivatives and hedging.
Derivatives, methods of accounting, derivatives not designated or qualifying as hedges	Derivatives Not Designated as Hedging Instruments Embedded Derivatives . The Company is deemed to have foreign currency forward contracts embedded in certain of the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved. These embedded derivatives are separated from their host contracts and carried on the Company’s balance sheet at their fair value. The majority of these embedded derivatives arise as a result of the Company’s foreign subsidiaries pricing their customer contracts in the U.S. dollar. Gains and losses on these embedded derivatives are included within revenues in the Company’s condensed consolidated statements of operations. During the three months ended June 30, 2016, gains (losses) associated with these embedded derivatives were not significant. During the three months ended June 30, 2015, the losses associated with these embedded derivatives were $2,057,000 . During the six months ended June 30, 2016, the losses associated with these embedded derivatives were $8,061,000 . During the six months ended June 30, 2015, gains (losses) associated with these embedded derivatives were not significant. Economic Hedges of Embedded Derivatives. The Company uses foreign currency forward contracts to manage the foreign exchange risk associated with the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved (“economic hedges of embedded derivatives”). Foreign currency forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. Gains and losses on these contracts are included in revenues along with gains and losses of the related embedded derivatives. The Company entered into various economic hedges of embedded derivatives during the three and six months ended June 30, 2016 and 2015 . During the three months ended June 30, 2016, the gains (losses) associated with these contracts were not significant. During the six months ended June 30, 2016, the gains associated with these contracts were $5,578,000 . During the three and six months ended June 30, 2015, the gains (losses) from these contracts were not significant. Foreign Currency Forward and Option Contracts. The Company also uses foreign currency forward and option contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities. As a result of foreign currency fluctuations, the U.S. dollar equivalent values of its foreign currency-denominated assets and liabilities change. Gains and losses on these contracts are included in other income (expense), net, along with foreign currency gains and losses of the related foreign currency-denominated assets and liabilities associated with these foreign currency forward and option contracts. The Company entered into various foreign currency forward and option contracts during the three and six months ended June 30, 2016 and 2015.
