Accounting Policies [Abstract]
Nature of Business and Summary of Significant Accounting Policies	Nature of Business and Summary of Significant Accounting Policies Nature of Business Equinix, Inc. (“Equinix” or the “Company”) was incorporated in Delaware on June 22, 1998. Equinix provides colocation space and related services. Global enterprises, content providers, financial companies and network service providers rely upon Equinix’s insight and expertise to safehouse and connect their most valued information assets. The Company operates International Business Exchange TM (“IBX®”) data centers, or IBX data centers across Americas; Europe, Middle East and Africa (“EMEA”) and Asia-Pacific geographic regions where customers directly interconnect with a network ecosystem of partners and customers. More than 1,400 network service providers offer access to the world’s internet routes inside the Company’s IBX data centers. This access to internet routes provides Equinix customers improved reliability and streamlined connectivity while significantly reducing costs by reaching a critical mass of networks within a centralized physical location. The Company began operating as a Real Estate Investment Trust ("REIT") for federal income tax purposes effective January 1, 2015. See “Income Taxes” in Note 14 below for additional information. On November 2, 2015, the Company acquired Bit-isle, Inc. ("Bit-isle"), a Tokyo-based company which primarily provides data center services in Japan. On January 15, 2016, the Company completed its acquisition of Telecity Group plc ("TelecityGroup") which provides data center services in Europe. On August 1, 2016, the Company completed the purchase of Digital Realty's operating business in Paris (the "Paris IBX Data Center Acquisition"), which currently houses Equinix' Paris 2 and Paris 3 data centers. As a result of these acquisitions, the Company operates 150 IBX data centers in 41 markets across five continents. Basis of Presentation, Consolidation and Foreign Currency The accompanying consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of the Paris IBX Data Center from August 1, 2016, TelecityGroup from January 15, 2016, Bit-isle from November 2, 2015 and Nimbo Technologies Inc. ("Nimbo") from January 14, 2015. All intercompany accounts and transactions have been eliminated in consolidation. Foreign exchange gains or losses resulting from foreign currency transactions, including intercompany foreign currency transactions, that are anticipated to be repaid within the foreseeable future, are reported within other income (expense) on the Company’s accompanying consolidated statements of operations. For additional information on the impact of foreign currencies to the Company’s consolidated financial statements, see “Accumulated Other Comprehensive Loss” in Note 12. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States ("U.S.") 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, fair values of financial instruments, intangible assets and goodwill, useful lives of intangible assets and property, plant and equipment, assets acquired and liabilities assumed from acquisitions, asset retirement obligations, restructuring charges, redemption value of redeemable non-controlling interests and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. Cash, Cash Equivalents and Short-Term and Long-Term Investments The Company considers all highly liquid instruments with an original maturity from the date of purchase of three months or less to be cash equivalents. Cash equivalents consist of money market mutual funds and highly liquid debt securities of corporations and certificates of deposit with original maturities up to 90 days. Short-term investments generally consist of debt securities with original maturities of between 90 days and one year. Long-term investments consist of debt securities with original maturities greater than 365 days and publicly traded equity securities. The Company’s fixed income securities and publicly traded equity securities are classified as “available-for-sale” and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income (loss). The cost of securities sold is based on the specific identification method. The Company reviews its investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades. Equity Method and Cost Method Investments The Company's non-marketable securities are accounted under the cost method. The Company records the dividends declared by the investees in other income and expense in the consolidated statement of operations and records any dividends in excess of earnings as a reduction of cost of investment. The Company's other equity investments include private equity investments which are accounted under the equity method. The Company adjusts the carrying amount of an investment for its share of the earnings and losses of the investees and recognizes its share of income or loss in other income and expense in the consolidated statement of operations. The Company records cost method and equity method investments in other assets in the consolidated balance sheet. The Company reviews these investments periodically to determine if any investments may be other-than-temporarily impaired primarily based on the financial condition and near-term prospects of these companies and funds. Financial Instruments and Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, short-term investments, long-term investments and accounts receivable. Risks associated with cash, cash equivalents, short-term investments and long-term investments are mitigated by the Company’s investment policy, which limits the Company’s investing to only those marketable securities rated at least A-1/P-1 Short Term Rating and A-/A3 Long Term Rating, as determined by independent credit rating agencies. Risk to the Company’s investment portfolio is further mitigated by its significant weighting in U.S. government securities in order to achieve REIT asset measure requirements. A significant portion of the Company’s customer base is comprised of businesses throughout the Americas. However, a portion of the Company’s revenues are derived from the Company’s EMEA and Asia-Pacific operations. The following table sets forth percentages of the Company’s revenues by geographic region for the years ended December 31: 2016 2015 2014 Americas 47 % 55 % 56 % EMEA 32 % 26 % 26 % Asia-Pacific 21 % 19 % 18 % No single customer accounted for greater than 10% of accounts receivable or revenues as of or for the years ended December 31, 2016, 2015 and 2014. Property, Plant and Equipment Property, plant and equipment are stated at the Company’s original cost or fair value for acquired property, plant and equipment. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements and integral equipment at leased locations are amortized over the shorter of the lease term or the estimated useful life of the asset or improvement. Leasehold improvements acquired in a business combination are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date of acquisition. Leasehold improvements that are placed into service significantly after and not contemplated at or near the beginning of the lease term are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date the leasehold improvements are purchased. The Company’s estimated useful lives of its property, plant and equipment are as follows: Core systems 3-25 years Buildings 12-50 years Leasehold improvements 12-40 years Construction in progress N/A Personal Property 3-10 years The Company’s construction in progress includes direct and indirect expenditures for the construction and expansion of IBX data centers and is stated at original cost. The Company has contracted out substantially all of the construction and expansion efforts of its IBX data centers to independent contractors under construction contracts. Construction in progress includes costs incurred under construction contracts including project management services, engineering and schematic design services, design development, construction services and other construction-related fees and services. In addition, the Company has capitalized interest costs during the construction phase. Once an IBX data center or expansion project becomes operational, these capitalized costs are allocated to certain property, plant and equipment categories and are depreciated over the estimated useful life of the underlying assets. Asset Retirement Costs The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred. The associated retirement costs are capitalized and included as part of the carrying value of the long-lived asset and amortized over the useful life of the asset. Subsequent to the initial measurement, the Company accretes the liability in relation to the asset retirement obligations over time and the accretion expense is recorded as a cost of revenue. The Company’s asset retirement obligations are primarily related to its IBX data centers, of which the majority are leased under long-term arrangements, and, in certain cases, are required to be returned to the landlords in their original condition. The majority of the Company’s IBX data center leases have been subject to significant development by the Company in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. The majority of the Company’s IBX data centers’ initial lease terms expire at various dates ranging from 2017 to 2065 and most of them enable the Company to extend the lease terms. Goodwill and Other Intangible Assets The Company has three reportable segments comprised of the 1) Americas, 2) EMEA and 3) Asia-Pacific geographic regions, which the Company also determined are its reporting units. As of December 31, 2016, the Company had goodwill attributable to its Americas, EMEA and Asia-Pacific reporting units. The Company has the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test is unnecessary. However, if the Company concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test. The first step, identifying a potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step would need to be conducted; otherwise, no further steps are necessary as no potential impairment exists. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. In 2016, the Company elected to bypass the qualitative assessment and performed the first step of the two-step goodwill impairment test for its Americas, EMEA and Asia-Pacific reporting units during the quarter ended December 31, 2016. In order to determine the fair value of each reporting unit, the Company utilizes the discounted cash flow and market methods. The assumptions supporting the discounted cash flow method was determined using the Company’s best estimates as of the date of the impairment review. As of October 31, 2016, the Company concluded that it was more likely than not that goodwill attributed to the Company’s Americas, EMEA and Asia-Pacific reporting units was not impaired as the fair value of each reporting unit exceeded the carrying value of its respective reporting unit, including goodwill. In addition, the Company concluded that no events occurred or circumstances changed subsequent to October 31, 2016 through December 31, 2016 that would more likely than not reduce the fair value of the Americas, EMEA and Asia-Pacific reporting units below its carrying value. In 2015, the Company assessed qualitative and quantitative factors to determine whether it was more likely than not that the fair value of its Americas reporting unit, EMEA reporting unit and Asia-Pacific reporting unit was less than its carrying value and concluded that it was more likely than not that goodwill was not impaired. Impairment assessments inherently involve judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact the Company’s assumptions as to prices, costs, growth rates or other factors that may result in changes in the Company’s estimates of future cash flows. Although the Company believes the assumptions it used in its evaluation of impairment are reasonable, significant changes in any one of the Company’s assumptions could produce a significantly different result. Indicators of potential impairment that might lead the Company to perform interim goodwill impairment assessments include significant and unforeseen customer losses, a significant adverse change in legal factors or in the business climate, a significant adverse action or assessment by a regulator, a significant stock price decline or unanticipated competition. For further information on goodwill and other intangible assets, see Note 6 below. Debt Issuance Costs Loan fees and costs are capitalized and are amortized over the life of the related loans based on the effective interest method. Such amortization is included as a component of interest expense. Debt issuance costs related to outstanding debt are presented as a reduction of the carrying amount of the debt liability and debt issuance costs related to the revolving credit facility are presented as other assets. Debt issuance costs related to the unsecured bridge facility and undrawn Term B-2 Loan are presented as other current assets. Derivatives and Hedging Activities The Company recognizes all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the value of a derivative depends on whether the contract is for trading purposes or has been designated and qualifies for hedge accounting. In order to qualify for hedge accounting, a derivative must be considered highly effective at reducing the risk associated with the exposure being hedged. In order for a derivative to be designated as a hedge, there must be documentation of the risk management objective and strategy, including identification of the hedging instrument, the hedged item and the risk exposure, and how effectiveness is to be assessed prospectively and retrospectively. Foreign currency gains or losses associated with derivatives that do not qualify for hedge accounting are recorded within other income (expense) in the Company’s consolidated statements of operations, with the exception of foreign currency embedded derivatives contained in certain of the Company’s customer contracts (see “Revenue Recognition” below), which are recorded within revenues in the Company’s consolidated statements of operations. To assess effectiveness of derivatives that qualify for hedge accounting, the Company uses a regression analysis. The extent to which a hedging instrument has been and is expected to continue to be effective at achieving offsetting changes in cash flows is assessed and documented at least quarterly. Any ineffectiveness is reported in current-period earnings. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued. For qualifying cash flow hedges, the effective portion of the change in the fair value of the derivative is recorded in other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged cash flows affect earnings. The ineffective portion of cash flow hedges is immediately recognized in earnings. If the hedge relationship is terminated, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the cash flows that were hedged occur, consistent with the original hedge strategy. For hedge relationships discontinued because the forecasted transaction is not expected to occur according to the original strategy, any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings. The Company does not use derivatives for speculative or trading purposes. For further information on derivatives and hedging activities, see Note 7 below. Fair Value of Financial Instruments The carrying value of the Company’s cash and cash equivalents, short-term and long-term investments represent their fair value, while the Company’s accounts receivable, accounts payable and accrued expenses and accrued property, plant and equipment approximate their fair value due primarily to the short-term maturity of the related instruments. The fair value of the Company’s debt, which is traded in the public debt market, is based on quoted market prices. The fair value of the Company’s debt, which is not publicly traded, is estimated by considering the Company’s credit rating, current rates available to the Company for debt of the same remaining maturities and terms of the debt. Fair Value Measurements The Company measures and reports certain financial assets and liabilities at fair value on a recurring basis, including its investments in money market funds and available-for-sale debt investments in other public companies, governmental units and other agencies, publicly traded equity securities and derivatives. The Company also follows the accounting standard for the measurement of fair value for non-financial assets and liabilities on a nonrecurring basis. These include: • Non-financial assets and non-financial liabilities initially measured at fair value in a business combination or other new basis event, but not measured at fair value in subsequent reporting periods; • Reporting units and non-financial assets and non-financial liabilities measured at fair value for goodwill impairment tests; • Indefinite-lived intangible assets measured at fair value for impairment assessments; • Non-financial long-lived assets or asset groups measured at fair value for impairment assessments or disposal; • Asset retirement obligations initially measured at fair value but not subsequently measured at fair value; and • Non-financial liabilities associated with exit or disposal activities initially measured at fair value but not subsequently measured at fair value. For further information on fair value measurements, see Note 8 below. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable such as a significant decrease in market price of a long-lived asset, a significant adverse change in legal factors or business climate that could affect the value of a long-lived asset or a continuous deterioration of the Company’s financial condition. Recoverability of assets to be held and used is assessed by comparing the carrying amount of an asset to estimated undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated discounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. The Company did not record any impairment charges related to its long-lived assets during the years ended December 31, 2016, 2015 and 2014. The Company recorded an impairment charges of $7,698,000 relating to assets held for sale for the year ended December 31, 2016, see Note 4 below. Revenue Recognition Equinix derives more than 90% of its revenues from recurring revenue streams, consisting primarily of (1) colocation, which includes the licensing of cabinet space and power; (2) interconnection offerings, such as cross connects and Equinix Exchange ports; (3) managed infrastructure services and (4) other revenues consisting of rental income from tenants or subtenants. The remainder of the Company’s revenues are from non-recurring revenue streams, such as installation revenues, professional services, contract settlements and equipment sales. Revenues from recurring revenue streams are generally billed monthly and recognized ratably over the term of the contract, generally one to three years for IBX data center colocation customers. Non-recurring installation fees, although generally paid in a lump sum upon installation, are deferred and recognized ratably over the period the customer is expected to benefit from the installation. Professional service fees are recognized in the period in which the services were provided and represent the culmination of a separate earnings process as long as they meet the criteria for separate recognition under the accounting standard related to revenue arrangements with multiple deliverables. Revenue from bandwidth and equipment sales is recognized on a gross basis in accordance with the accounting standard related to reporting revenue gross as a principal versus net as an agent, primarily because the Company acts as the principal in the transaction, takes title to products and services and bears inventory and credit risk. To the extent the Company does not meet the criteria for recognizing bandwidth and equipment services as gross revenue, the Company records the revenue on a net basis. Revenue from contract settlements, when a customer wishes to terminate their contract early, is generally recognized on a cash basis, when no remaining performance obligations exist, to the extent that the revenue has not previously been recognized. The Company guarantees certain service levels, such as uptime, as outlined in individual customer contracts. To the extent that these service levels are not achieved, the Company reduces revenue for any credits given to the customer as a result. The Company generally has the ability to determine such service level credits prior to the associated revenue being recognized, and historically, these credits have generally not been significant. There were no significant service level credits issued during the years ended December 31, 2016, 2015 and 2014. Revenue is recognized only when the service has been provided and when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the receivable is reasonably assured. It is the Company’s customary business practice to obtain a signed master sales agreement and sales order prior to recognizing revenue in an arrangement. Taxes collected from customers and remitted to governmental authorities are reported on a net basis and are excluded from revenue. As a result of certain customer agreements being priced in currencies different from the functional currencies of the parties involved, under applicable accounting rules, the Company is deemed to have foreign currency forward contracts embedded in these contracts. The Company refers to these as foreign currency embedded derivatives (see Note 7). These instruments are separated from their host contracts and held on the Company’s consolidated balance sheet at their fair value. The majority of these foreign currency embedded derivatives arise in certain of the Company’s subsidiaries where the local currency is the subsidiary’s functional currency and the customer contract is denominated in the U.S. dollar. Changes in their fair values are recognized within revenues in the Company’s consolidated statements of operations. The Company assesses collectability based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The Company generally does not request collateral from its customers although in certain cases the Company obtains a security interest in a customer’s equipment placed in its IBX data centers or obtains a deposit. If the Company determines that collection of a fee is not reasonably assured, the fee is deferred and revenue is recognized at the time collection becomes reasonably assured, which is generally upon receipt of cash. In addition, the Company also maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments for which the Company had expected to collect the revenues. If the financial condition of the Company’s customers were to deteriorate or if they became insolvent, resulting in an impairment of their ability to make payments, greater allowances for doubtful accounts may be required. Management specifically analyzes accounts receivable and current economic news and trends, historical bad debts, customer concentrations, customer credit-worthiness and changes in customer payment terms when evaluating revenue recognition and the adequacy of the Company’s reserves. Any amounts that were previously recognized as revenue and subsequently determined to be uncollectible are charged to bad debt expense included in general and administrative expense in the consolidated statements of operations. A specific bad debt reserve of up to the full amount of a particular invoice value is provided for certain problematic customer balances. An additional reserve is established for all other accounts based on the age of the invoices and an analysis of historical credits issued. Delinquent account balances are written-off after management has determined that the likelihood of collection is not probable. Income Taxes Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are expected more likely than not to be realized in the future. A tax benefit from an uncertain income tax position may be recognized in the financial statements only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. The Company began operating as a REIT for federal income tax purposes effective January 1, 2015, and thereafter received a favorable private letter ruling (“PLR”) from the U.S. Internal Revenue Service (“IRS”) that validated the Company's position with respect to specified REIT compliance matters. As a result, the Company may deduct the distributions made to its stockholders from taxable income generated by the Company's Qualified REIT Subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the U.S. taxable income of the Company's 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 TRS. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax benefit (expense) in the consolidated statements of operations. Stock-Based Compensation Stock-based compensation cost is measured at the grant date for all stock-based awards made to employees and directors based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period. The Company grants restricted stock units to its employees and these equity awards generally have only a service condition. The Company grants restricted stock units to its executives and these awards generally have a service and performance condition or a service and market condition. To date, any performance conditions contained in an equity award are tied to the financial performance of the Company or a specific region of the Company. The Company assesses the probability of meeting these performance conditions on a quarterly basis. The majority of the Company’s equity awards vest over four years, although certain of the equity awards for executives vest over a range of two to four 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 uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition. The Company uses the Black-Scholes option-pricing model to determine the fair value of its employee stock purchase plan. The determination of the fair value of shares purchased under the employee stock purchase plan is affected by assumptions regarding a number of complex and subjective variables including the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock purchase behaviors. The Company estimated the expected volatility by using the average historical volatility of its common stock that it believed was best representative of future volatility. The risk-free interest rate used was based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term of the equity awards. The expected dividend rate used in 2015 and thereafter was based on average dividend yields and the expected dividend rate used prior to 2015 was zero as the Company did not anticipate paying dividends. The expected term used was equal to the term of each purchase window. The accounting standard for stock-based compensation does not allow the recognition of unrealized tax benefits associated with the tax deductions in excess of the compensation recorded (excess tax benefit) until the excess tax benefit is realized (i.e., reduces taxes payable). The Company recognizes the benefit from stock-based compensation in equity when the excess tax benefit is realized by following the “with-and-without” approach. For further information on stock-based compensation, see Note 13 below. Foreign Currency Translation The financial position of foreign subsidiaries is translated using the exchange rates in effect at the end of the period, while income and expense items are translated at average rates of exchange during the period. Gains or losses from translation of foreign operations where the local currency is the functional currency are included as other comprehensive income (loss). The net gains and losses resulting from foreign

Business Combinations [Abstract]
Acquisitions	Acquisitions Offer for Certain Verizon Data Center Assets On December 6, 2016, the Company entered into a transaction agreement with Verizon Communications Inc. ("Verizon") to acquire Verizon's colocation services business at 24 data center sites, consisting of 29 data center buildings, located in the United States, Brazil and Colombia, for a cash purchase price of $3,600,000,000 . The acquisition is expected to close by mid-2017. The Company expects to fund the acquisition with a combination of cash on hand and proceeds of debt and equity financings. The Company expects to account for the Verizon data center sites acquisition as a business combination using the acquisition method of accounting. In connection with the Verizon data center sites acquisition, the Company entered into a commitment letter (the "Commitment Letter"), dated December 6, 2016, with JPMorgan Chase Bank, N.A., Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Commitment Parties"), pursuant to which the Commitment Parties have committed to provide a senior unsecured bridge facility in an aggregate principal amount of $2,000,000,000 for the purposes of funding (i) a portion of the cash consideration for the acquisition and (ii) the fees and expenses incurred in connection with the acquisition. The full amount must be drawn in a single drawing. The initial maturity date is 12 months from the date of the drawdown and, at the initial maturity date (if not repaid prior to that time), it will be converted into a seven-year senior unsecured term loan. Advances funded under the bridge facility shall accrue interest per annum at a rate of 4.25% which will increase by an additional 25 basis points 30 days after the closing date, by an additional 25 basis points 60 days after the closing date, by an additional 50 basis points 90 days after the closing date, and by an additional 50 basis points 120 days after the closing date, to the total cap, which is 1.75% per annum plus the greatest of (i) the yield per annum on the 5.875% Senior Notes Due 2016 (on the basis of the yield to maturity thereof), (ii) the yield per annum on the J.P. Morgan US Dollar Global High Yield Index minus 1.61% and (iii) 5.250% per annum, 180 days after the closing date. Commitment fees associated with the Commitment Letter are equal to (i) 0.50% of the commitment plus (ii) an additional 0.25% of the commitment that is four months after the date in which the Commitment Letter was entered into. As of December 31, 2016, the Company had accrued $10,000,000 of commitment fees associated with the Commitment Letter and amortized $2,174,000 to interest expense in the consolidated statement of operations. As of December 31, 2016, the Company had not drawn against the Commitment Letter. Paris IBX Data Center Acquisition On August 1, 2016, the Company completed the purchase of Digital Realty Trust, Inc.'s ("Digital Realty's") operating business, including its real estate and facility, located in St. Denis, Paris for cash consideration of approximately €193,768,000 or $216,400,000 at the exchange rate in effect on August 1, 2016 (the "Paris IBX Data Center Acquisition"). A portion of the building was leased to the Company and was being used by the Company as its Paris 2 and Paris 3 data centers. The Paris 2 lease was accounted for as an operating lease and the Paris 3 lease was accounted for as a financing lease. Upon acquisition, the Company in effect terminated both leases. The Company settled the financing lease obligation of Paris 3 for €47,790,000 or approximately $53,372,000 and recognized a loss on debt extinguishment of €8,828,000 or approximately $9,894,000 . The Paris IBX Data Center Acquisition constitutes a business under the accounting standard for business combinations and as a result, the Paris IBX Data Center Acquisition was accounted for as a business combination using the acquisition method of accounting. The Company included the incremental Paris IBX Data Center's results of operations from August 1, 2016 and the estimated fair value of assets acquired and liabilities assumed in its consolidated balance sheets beginning August 1, 2016. The Company incurred acquisition costs of approximately $11,978,000 for the year ended December 31, 2016 related to the Paris IBX Data Center Acquisition. Purchase Price Allocation Under the acquisition method of accounting, the total purchase price is allocated to the assets acquired and liabilities assumed measured at fair value on the date of acquisition. As of the date of this annual report, the Company had completed the detailed valuation analysis to derive the fair value of the following items including, but not limited to property, plant and equipment, intangible assets and leasehold interests. During the fourth quarter of 2016, the Company recorded certain measurement period adjustments that were insignificant to the results from operations for the year ended December 31, 2016. The purchase price allocation, which excludes settlement of the Paris 3 financing obligations, was as follows (in thousands): Cash and cash equivalent $ 4,073 Accounts receivable 1,507 Other current assets 794 Property, plant and equipment 143,972 Intangible assets 11,758 Goodwill 48,835 Other assets 81 Total assets acquired 211,020 Accounts payable and accrued liabilities (2,044 ) Other current liabilities (2,798 ) Deferred tax liabilities (42,395 ) Other liabilities (755 ) Net assets acquired $ 163,028 Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. 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. 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) In-place leases $ 7,485 0.9 - 9.4 4.3 Favorable leasehold interests 4,273 1.9 - 6.7 5.3 The fair value of in-place lease value may consist of a variety of components including, but not necessarily limited to: the value associated with avoiding the cost of originating the acquired in-place leases. The fair value of favorable leases was estimated based on the income approach, by computing the net present value of the difference between the contractual amounts to be paid pursuant to the lease agreements and estimates of the fair market lease rates for the corresponding in place leases measured over remaining non-cancellable terms of the leases. 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, such as cash flows or earnings that an asset can be expected to generate over its useful life or the replacement or reproduction cost. For the year ended December 31, 2016 , the incremental revenues from the Paris IBX Data Center Acquisition were $4,084,000 and the incremental net income was not significant to the Company’s consolidated statement of operations. The incremental results of operations from the Paris IBX Data Center Acquisition are not significant; therefore the Company does not present pro forma combined results of operations. 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 at the exchange rate in effect on the acquisition date. 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 $42,490,000 during the year ended December 31, 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 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. 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. 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 annual report, the Company has 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. Prior quarterly reports reported the allocation of the purchase price to acquired assets and liabilities based on provisional estimates that were subject to continuing management analysis. As of December 31, 2016, the Company has updated the final allocation of purchase price for TelecityGroup from provisional amounts reported as of March 31, 2016, which primarily resulted in increases to intangible assets of $36,758,000 and deferred tax liabilities of $19,500,000 and decreases in capital lease and other financing obligations of $34,443,000 , goodwill of $22,511,000 and assets held for sale of $36,865,000 . The changes did not have a significant impact on the Company’s results from operations for the year ended December 31, 2016. As of the acquisition date, the allocation of the purchase price was as follows (in thousands): Cash and cash equivalents $ 73,368 Accounts receivable 24,042 Other current assets 41,079 Assets held for sale 877,650 Property, plant and equipment 1,058,583 Goodwill 2,215,567 Intangible assets 694,243 Deferred tax assets 994 Other assets 4,102 Total assets acquired 4,989,628 Accounts payable and accrued expenses (84,367 ) Accrued property, plant and equipment (3,634 ) Other current liabilities (27,233 ) Liabilities held for sale (155,650 ) Capital lease and other financing obligations (165,365 ) Mortgage and loans payable (592,304 ) Deferred tax liabilities (176,168 ) Other liabilities (40,021 ) Net assets acquired $ 3,744,886 The 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 $ 591,956 13.5 13.5 Trade names 72,033 1.5 1.5 Favorable leases 30,254 2.0 - 25.4 19.7 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's trade names 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 life. There are two primary methods of applying the income approach to determine the fair value of 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 for which the asset could be replaced or reproduced. The key assumptions of the cost approach include replacement cost, 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 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. 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. The Company's results of continuing operations include TelecityGroup revenues of $399,978,000 and net loss from continuing operations of $47,133,000 for the period January 15, 2016 through December 31, 2016. Bit-isle Acquisition On November 2, 2015, the Company, acting through its Japanese subsidiary, 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 ¥33,196,000,000 or approximately $275,367,000 at the exchange rate in effect on the date of the acquisition. On September 30, 2015, the Company, acting through its Japanese subsidiaries as borrowers, 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 $395,675,000 at the exchange rate in effect on September 30, 2015. 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. In October 2016, the Company borrowed ¥47,500,000,000 on a five year term loan agreement with BTMU and repaid the Bridge Term Loan. See Note 10 for further information. 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 incurred acquisition costs of approximately $8,645,000 for the year ended December 31, 2015 related to the Bit-isle Acquisition. In June 2016, the Company approved the divestiture of the solar power assets of Bit-isle. See Note 4 below for further information. 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. Based upon the purchase price and the valuation of Bit-isle, the final purchase price allocation was as follows (in thousands): Cash and cash equivalent $ 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 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 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 reportable segment (see Note 17) and reporting unit (see Note 6). For the year ended December 31, 2015, the Company's results of continuing operations include Bit-isle revenues of $21,588,000 and net losses of $3,233,000 . 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 acquisition as though it occurred on January 1, 2015 and the Bit-isle acquisition as though it occurred on January 1, 2014. The Company completed the TelecityGroup acquisition on January 15, 2016 and the Bit-isle acquisition on November 2, 2015. TelecityGroup's operating results for the period January 15, 2016 through December 31, 2016 are included in the consolidated statement of operations for the year ended December 31, 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 years ended December 31, 2015 and 2014 (in thousands): 2015 2014 Revenues $ 3,244,349 $ 2,614,127 Net income from continuing operations 141,496 (251,067 ) Basic EPS 2.10 (4.80 ) Diluted EPS 2.08 (4.80 ) Nimbo Acquisition On January 14, 2015, the Company acquired all of the issued and outstanding share capital of Nimbo Technologies Inc. (“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”). Nimbo continues to operate under the Nimbo name. 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. ALOG Acquisition On April 25, 2011, the Company and RW Brasil Fundo de Investimento em Participações, a subsidiary of Riverwood Capital L.P. (“Riverwood”), completed the acquisition of approximately 90% of the outstanding capital stock of ALOG Data Centers do Brasil S.A. (“ALOG”). As a result, the Company acquired an approximate 53% controlling equity interest in ALOG (the “ALOG Acquisition”). In July 2014, the Company and Riverwood entered into a purchase and sale agreement in which the Company acquired Riverwood’s interest in ALOG and the approximate 10% of ALOG owned by ALOG management, which resulted in the Company owning 100% of ALOG. The net purchase price of $225,629,000 consisted of: (i) $216,484,000 of cash paid to Riverwood and ALOG management to acquire their interests in ALOG, (ii) $8,459,000 of cash paid for the common shares of ALOG related to vested and outstanding stock options to purchase common shares of ALOG that were held by ALOG employees and (iii) $686,000 for the assumption of Riverwood’s portion of the contingent consideration in connection with the acquisition of ALOG in 2011. The cash portion of the purchase price was paid on the closing date in July 2014. The net increase in the redemption value of the redeemable non-controlling interests of $90,966,000 and transaction costs of $1,333,000 were recorded in additional paid-in capital during the year ended December 31, 2014.

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 and the Company recognized a gain on sale of $5,242,000 . 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 London 2 data center ("LD2") and certain data centers of TelecityGroup in the United Kingdom ("UK"), 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 divestiture. The divestiture was completed on July 5, 2016 and the Company recognized a gain of $27,945,000 on the sale of the LD2 data center, which is included in gain on asset sales in the consolidated statement of operations for year ended December 31, 2016. During the years ended December 31, 2016, 2015 and 2014, LD2 data center generated revenue of $6,116,000 , $17,579,000 and $21,772,000 , respectively, and net income of $2,327,000 , $7,166,000 and $9,218,000 , 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 consolidated balance sheet through July 5, 2016, the date the divestiture closed. The results of operations for the TelecityGroup data centers that were divested, as well as the gain on divestiture, were classified as discontinued operations from January 15, 2016, the date the acquisition closed, through July 5, 2016 (see Note 5). In June 2016, the Company approved the divestiture of the solar power assets of Bit-isle. In October 2016, the Company entered into a Share Transfer Agreement for the transfer of common stock of Terra Power Co., Ltd., relating to the divestiture of the solar power assets of Bit-isle. The Company received ¥400,000,000 upon the closing of the transaction, or approximately $3,816,000 at the exchange rate in effect on October 31, 2016. By November 30, 2016, the Company had received an additional ¥2,500,000,000 , or approximately $22,083,000 at the exchange rate in effect at the time of cash receipt. The Company expects to receive the remaining payment of ¥5,313,384,000 in the first quarter of 2017, or approximately $45,483,000 at the exchange rate in effect on December 31, 2016. The associated loss on the sale was insignificant. Furthermore, the revenue and net income generated by the solar power assets of Bit-isle during the years ended December 31, 2016 and 2015 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. During the quarter ended September 30, 2016, the Company evaluated the recoverability of the carrying value of its assets held for sale. Based on the analysis, it was determined that during negotiation of the sales agreement, the Company would not recover the carrying value of certain assets. Accordingly, the Company recorded an impairment charge on other current assets of $7,698,000 in the third quarter of 2016, reducing the carrying value of such assets from $79,459,000 to the estimated fair value of $71,761,000 . The revenue and net income generated by the solar power assets of Bit-isle during the year ended December 31, 2016 were insignificant. The following table summarizes the assets and liabilities that were classified in assets and liabilities held for sale in the consolidated balance sheet as of December 31 (in thousands): 2016 2015 Accounts receivable $ — $ 2,222 Other current assets — 408 Property, plant and equipment — 23,533 Goodwill — 5,000 Intangible assets — 784 Other assets — 1,310 Total assets held for sale $ — $ 33,257 Accounts payable and accrued expenses $ — $ (654 ) Accrued property, plant and equipment — (816 ) Other current liabilities — (435 ) Other liabilities — (1,630 ) Total liabilities held for sale $ — $ (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. On July 5, 2016, the Company completed the sale of these data centers and related assets to Digital Realty for approximately €304,564,000 and £376,171,000 , or approximately total of $827,314,000 at the exchange rates in effect on July 5, 2016. The Company recognized a gain on sale of the TelecityGroup data centers in discontinued operations of $2,351,000 . The results of operations for these data centers that were divested, as well as the gain on divestiture, have been reported as net income from discontinued operations, net of tax, from January 15, 2016, the date of the acquisition, through July 5, 2016 in the Company's consolidated statement of operations. The following table presents the financial results of the Company's discontinued operations for the year ended December 31, 2016. The Company didn't record income from discontinued operations, net of income taxes for the years ended December 31, 2015 and 2014. 2016 Revenue $ 48,782 Costs and operating expenses: Cost of revenues 24,795 Sales and marketing 1,030 General and administrative 7,026 Total costs and operating expenses 32,851 Income from operations of discontinued operations 15,931 Interest expense and other, net (1,286 ) Income from discontinued operations before income taxes 14,645 Income tax expense (4,604 ) Gain on sale of discontinued operations, net of income taxes 2,351 Income from discontinued operations, net of income taxes $ 12,392 As of the date of acquisition, depreciation and amortization of discontinued operations were ceased.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Instruments	Derivatives and Hedging Instruments Derivatives Designated as Hedging Instruments Net Investment Hedges. The Company is exposed to the impact of foreign exchange rate fluctuations on its investments in foreign subsidiaries whose functional currencies are other than the U.S. dollar. In order to mitigate the impact of 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. As of December 31, 2016 and 2015 , the total principal amount of foreign currency loans, which were designated as net investment hedges, was $646,219,000 and $411,881,000 , respectively. 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 foreign subsidiaries. For a net investment hedge, changes in the fair value of the hedging instrument designated as a net investment hedge, except the ineffective portion and forward points, are recorded as a component of other comprehensive income in the consolidated balance sheet. The Company recorded net foreign exchange gains of $45,505,000 and $4,484,000 , net of amounts reclassified to gain on sale of discontinued operations, in other comprehensive income (loss) for the years ended December 31, 2016 and 2015 , respectively. The Company recorded no ineffectiveness from its net investment hedges for the years ended December 31, 2016 and 2015 . Cash Flow Hedges. The Company hedges its foreign currency translation exposure for forecasted revenues and expenses in its EMEA region 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 began to enter into intercompany hedging instruments (“intercompany derivatives”) with a wholly-owned subsidiary of the Company in order to hedge certain forecasted revenues and expenses denominated in currencies other than the U.S. dollar. Simultaneously, the Company enters into derivative contracts with unrelated third parties to externally hedge the net exposure created by such intercompany derivatives. The following disclosure is prepared on a consolidated basis. Assets and liabilities resulting from intercompany derivatives have been eliminated in consolidation. As of December 31, 2016 , the Company's cash flow hedge instruments had maturity dates ranging from January 2017 to November 2018 as follows (in thousands): Notional Amount Fair Value (1) Accumulated Other Comprehensive Income (Loss) (2)(3) Derivative assets $ 545,638 $ 44,570 $ 42,634 Derivative liabilities 42,207 (1,815 ) (1,453 ) $ 587,845 $ 42,755 $ 41,181 __________________________ (1) All derivative assets related to cash flow hedges are included in the consolidated balance sheets within other current assets, other assets, other current liabilities and other liabilities. (2) Included in the consolidated balance sheets within accumulated other comprehensive income (loss). (3) The Company recorded a net gain of $31,896 within accumulated other comprehensive income (loss) relating to cash flow hedges that will be reclassified to revenue and expenses as they mature over the next 12 months. As of December 31, 2015 , the Company's cash flow hedge instruments had maturity dates ranging from January 2016 to December 2017 as follows (in thousands): Notional Amount Fair Value (1) Accumulated Other Comprehensive Income (Loss) (2)(3) Derivative assets $ 367,330 $ 16,027 $ 34,578 Derivative liabilities 47,447 (813 ) (19,709 ) $ 414,777 $ 15,214 $ 14,869 __________________________ (1) All derivative assets related to cash flow hedges are included in the consolidated balance sheets within other current assets, other assets, other current liabilities and other liabilities. (2) Included in the consolidated balance sheets within accumulated other comprehensive income (loss). (3) The Company recorded a net gain of $12,940 within accumulated other comprehensive income (loss) relating to cash flow hedges that will be reclassified to revenue and expenses as they mature over the next 12 months. During the years ended December 31, 2016 and 2015 , the ineffective and excluded portions of cash flow hedges recognized in other income (expense) were not significant. During the year ended December 31, 2016 , the amount of net gains reclassified from accumulated other comprehensive income (loss) to revenues was $38,427,000 and the amount of net losses reclassified from accumulated other comprehensive income (loss) to operating expenses were $19,908,000 . During the year ended December 31, 2015 , the amount of net gains reclassified from accumulated other comprehensive income (loss) to revenues was $27,973,000 and the amount of net losses reclassified from accumulated other comprehensive income (loss) to operating expenses was $6,256,000 . During the year ended December 31, 2014 , the amount of net gains reclassified from accumulated other comprehensive income (loss) to revenues was $4,332,000 and the amount of net losses reclassified from accumulated other comprehensive income (loss) to operating expenses was not significant. 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 consolidated statements of operations. During the years ended December 31, 2016 and 2015, the gain or loss associated with these embedded derivatives was insignificant. During the year ended December 31, 2014 , the Company recognized a net gain of $3,807,000 associated with these embedded derivatives. Economic Hedges of Embedded Derivatives. The Company uses foreign currency forward contracts to help 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 years ended December 31, 2016 , 2015 and 2014 . The Company recognized a net gain of $2,884,000 during the year ended December 31, 2016 and a net loss of $2,287,000 and $2,602,000 during the years ended December 31, 2015 and 2014 , respectively. 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 the foreign currency gains and losses of the related foreign currency-denominated assets and liabilities associated with these foreign currency forward contracts. The Company entered into various foreign currency forward and option contracts during the years ended December 31, 2016 , 2015 and 2014 . The Company recognized a net gain of $74,173,000 during the year ended December 31, 2016 . The Company recognized a net loss of $24,319,000 during the year ended December 31, 2015 and a net gain of $12,657,000 during the year ended December 31, 2014 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Valuation Methods Fair value estimates are made as of a specific point in time based on methods using the market approach valuation method which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities or other valuation techniques. These techniques involve uncertainties and are affected by the assumptions used and the judgments made regarding risk characteristics of various financial instruments, discount rates, estimates of future cash flows, future expected loss experience and other factors. Cash, Cash Equivalents and Investments. The fair value of the Company's investments in money market funds approximates their face value. Such instruments are included in cash equivalents. The Company’s money market funds and publicly traded equity securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices for identical instruments in active markets. The fair value of the Company's other investments approximate their face value and include certificates of deposit. The fair value of these investments is priced based on the quoted market price for similar instruments or nonbinding market prices that are corroborated by observable market data. Such instruments are classified within Level 2 of the fair value hierarchy. The Company determines the fair values of its Level 2 investments by using inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, custody bank, third-party pricing vendors, or other sources. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company is responsible for its consolidated financial statements and underlying estimates. The Company uses the specific identification method in computing realized gains and losses. Realized gains and losses on the investments are included within other income (expense) in the Company’s consolidated statements of operations. Short-term and long-term investments are classified as available-for-sale and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income or loss, net of any related tax effect. The Company reviews its investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades over an extended period of time. Derivative Assets and Liabilities . For derivatives, the Company uses forward contract and option models employing market observable inputs, such as spot currency rates and forward points with adjustments made to these values utilizing published credit default swap rates of its foreign exchange trading counterparties and other comparable companies. The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, therefore the derivatives are categorized as Level 2. During the years ended December 31, 2016 and 2015 , the Company did not have any nonfinancial assets or liabilities measured at fair value on a recurring basis. The Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 were as follows (in thousands): Fair Value at December 31, Fair Value Measurement Using 2016 Level 1 Level 2 Assets: Cash $ 345,119 $ 345,119 $ — Money market and deposit accounts 400,388 400,388 — Publicly traded equity securities 6,463 6,463 — Certificates of deposit 9,957 — 9,957 Derivative instruments (1) 69,979 — 69,979 $ 831,906 $ 751,970 $ 79,936 Liabilities: Derivative instruments (1) $ 10,959 $ — $ 10,959 _________________________ (1) Includes both foreign currency embedded derivatives and foreign currency forward and option contracts.

The Senior Credit Facility contains two financial covenants with which the Company must comply on a quarterly basis, including a maximum consolidated net lease adjusted leverage ratio and a minimum consolidated fixed charge coverage ratio. The Senior Credit Facility is guaranteed by certain of the Company’s domestic subsidiaries and is secured by its domestic accounts receivable as well as pledges of the equity interest of certain of the Company’s direct and indirect subsidiaries. The Revolving Credit Facility and the Term Loan A Facility both have a five -year term, maturing on December 17, 2019 , subject to the satisfaction of certain conditions with respect to the Company’s outstanding convertible subordinated notes. The Company may use the remaining Senior Credit Facility for working capital, capital expenditures and other corporate purposes.

As of December 31, 2016 and 2015 , the Company had no preferred stock issued and outstanding. Common Stock In November 2015, the Company issued and sold 2,994,792 shares of its common stock in a public offering pursuant to a registration statement and a related prospectus and prospectus supplement, in each case filed with the Securities and Exchange Commission. The shares issued and sold included the full exercise of the underwriters’ option to purchase 390,625 additional shares.

In June 2016, the Company also settled the capped call transaction and received 380,779 shares of common stock, which were placed in treasury and resulted in a credit of $141,688,000 to additional paid in capital at the market price of $372.10 on June 15, 2016. See convertible debt in Note 10 for additional information. As of December 31, 2016 , the Company had reserved the following shares of authorized but unissued shares of common stock for future issuances: Common stock options and restricted stock units 5,134,885 Common stock employee purchase plans 3,427,867 Total 8,562,752 Accumulated Other Comprehensive Loss The components of the Company’s accumulated other comprehensive loss (OCI) consisted of the following as of December 31, 2014, 2015 and 2016 (in thousands): December 31, 2013 Net December 31, 2014 Net December 31, 2015 Net December 31, 2016 Foreign currency translation adjustment ("CTA") loss $ (132,881 ) $ (204,065 ) $ (336,946 ) $ (186,763 ) $ (523,709 ) $ (507,420 ) $ (1,031,129 ) Unrealized gain (loss) on cash flow hedges (1) (2,187 ) 8,790 6,603 4,550 11,153 19,551 30,704 Net investment hedge CTA gain (1) — — — 4,484 4,484 45,505 49,989 Unrealized gain (loss) on available for sale securities (2) 180 (279 ) (99 ) (40 ) (139 ) 2,249 2,110 Net actuarial gain (loss) on defined benefit plans (3) — (2,001 ) (2,001 ) 1,153 (848 ) 32 (816 ) OCI attributable to redeemable non-controlling interests (4) 21,121 (21,121 ) — — — — — $ (113,767 ) $ (218,676 ) $ (332,443 ) $ (176,616 ) $ (509,059 ) $ (440,083 ) $ (949,142 ) __________________________ (1) Refer to Note 7 for a discussion of the amounts reclassified from accumulated other comprehensive loss to net income (loss). (2) The realized gains and losses reclassified from accumulated other comprehensive loss to net income (loss) were insignificant for the year ended December 31, 2016 . (3) The Company has a defined benefit pension plan covering all employees in one country where such plans are mandated by law. The Company does not have any defined benefit plans in any other countries. The unamortized gain (loss) on defined benefit plans includes gains or losses resulting from a change in the value of either the projected benefit obligation or the plan assets resulting from a change in an actuarial assumption, net of amortization. (4) The Company purchased the redeemable non-controlling interests in ALOG in July 2014. Changes include $1,810 of other comprehensive income attributable to redeemable non-controlling interests for the seven months and $19,311 of accumulated other comprehensive income reclassified to additional paid-in capital upon the Company’s purchase of the redeemable non-controlling interests in ALOG in July 2014. Changes in foreign currencies 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 are generally translating into more U.S. dollars when the U.S. dollar weakens or less U.S. dollars when the U.S. dollar strengthens. At December 31, 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 strength of the U.S. dollar had an overall negative impact on the Company’s consolidated financial position because the foreign denominations translated into less U.S. dollars as evidenced by an increase in foreign currency translation loss for the year ended December 31, 2016 compared to the year ended December 31, 2015 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 does business 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. Share Repurchase Program 2013 Share Repurchase Program In December 2013, the Company’s Board of Directors (the “Board”) approved a share repurchase program (the “2013 Share Repurchase Program”) to repurchase up to $500,000,000 in value of the Company’s common stock in the open market or private transactions through December 31, 2014.

The number of shares distributed was determined based upon common stockholder elections and the average closing price of the Company’s common stock on the three trading days commencing on November 18, 2014 or $224.45 per share. As such, the Company issued 1,482,419 shares of its common stock and paid $83,266,000 in connection with the 2014 Special Distribution. Shares issued in connection with the 2015 Special Distribution and the 2014 Special Distribution impact weighted average shares outstanding from the date of issuance, thus impacting the Company’s earnings per share data prospectively from the distribution date.

The 2000 Equity Incentive Plan is administered by the Compensation Committee of the Board of Directors (the “Compensation Committee”), and the Compensation Committee may terminate or amend the plan, with approval of the stockholders as may be required by applicable law, at any time. In May 2000, the Company’s stockholders approved the adoption of the 2000 Director Option Plan, which was amended and restated effective January 1, 2003. Under the 2000 Director Option Plan, each non-employee board member who was not previously an employee of the Company will receive an automatic initial nonstatutory stock option grant, which vests in four annual installments. In addition, each non-employee board member will receive an annual non-statutory stock option grant on the date of the Company’s regular Annual Meeting of Stockholders, provided the board member will continue to serve as a director thereafter. Such annual option grants shall vest in full on the earlier of a) the first anniversary of the grant, or b) the date of the regular Annual Meeting of Stockholders held in the year following the grant date. A new director who receives an initial option will not receive an annual option in the same calendar year. Options granted under the 2000 Director Option Plan will have an option price not less than 100% of the fair value on the date of grant and will have a 10 -year contractual term, subject to continuous service of the board member. On December 18, 2008, the Company’s Board of Directors passed resolutions eliminating all automatic stock option grant mechanisms under the 2000 Director Option Plan, and replaced them with an automatic restricted stock unit grant mechanism under the 2000 Equity Incentive Plan. As of December 31, 2016 , the Company had reserved 594,403 shares for issuance under the 2000 Director Option Plan of which 505,646 were still available for grant. The 2000 Director Option Plan is administered by the Compensation Committee and the Compensation Committee may terminate or amend the plan, with approval of the stockholders as may be required by applicable law, at any time. In September 2001, the Company adopted the 2001 Supplemental Stock Plan, under which non-statutory stock options and restricted shares/restricted stock units may be granted to consultants and employees who are not executive officers or board members, at not less than 85% of the fair value on the date of grant. Options granted prior to October 1, 2005 generally expire 10 years from the grant date, and options granted on or after October 1, 2005 will generally expire seven years from the grant date, subject to continuous service of the optionee. Current stock options granted under the 2001 Supplemental Stock Plan generally vest over four years. As of December 31, 2016 , the Company had reserved a total of 1,494,275 shares for issuance under the 2001 Supplemental Stock Plan, of which 260,498 were still available for grant. The 2001 Supplemental Stock Plan is administered by the Compensation Committee, and the plan will continue in effect indefinitely unless the Compensation Committee decides to terminate it earlier. The 1998 Stock Plan, 2000 Equity Incentive Plan, 2000 Director Option Plan and 2001 Supplemental Stock Plan are collectively referred to as the “Equity Compensation Plans.” Stock Options Stock option activity under the Equity Compensation Plans is summarized as follows: Number of Shares Outstanding Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (1) (Dollars in Thousands) Stock options outstanding at December 31, 2013 148,055 $ 73.99 Stock options exercised (71,780 ) 72.44 Additional shares granted due to special distribution 1,659 — Stock options outstanding at December 31, 2014 77,934 73.84 Stock options exercised (41,889 ) 64.18 Additional shares granted due to special distribution 1,454 — Stock options expired (250 ) 41.12 Stock options outstanding at December 31, 2015 37,249 82.06 Stock options exercised (18,183 ) 80.10 Stock options outstanding at December 31, 2016 19,066 82.01 1.2 $ 5,251 Stock options vested and exercisable at December 31, 2016 19,066 82.01 1.2 $ 5,251 __________________________ (1) The aggregate intrinsic value is calculated as the difference between the market value of the stock as of December 31, 2016 and the exercise price of the option.

Restricted Stock Units Since 2008, the Company primarily grants restricted stock units to its employees, including executives and non-employee directors, in lieu of stock options. The Company generally grants restricted stock units that have a service condition only or have both a service and performance condition. Each restricted stock unit is not considered issued and outstanding and does not have voting rights until it is converted into one share of the Company’s common stock upon vesting. Restricted stock unit activity is summarized as follows: Number of Shares Outstanding Weighted Average Grant Date Fair Value per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (1) (Dollars in Thousands) Restricted stock units outstanding, December 31, 2013 1,509,382 $ 122.05 Restricted stock units granted 803,692 190.90 Additional shares granted due to special distribution 48,171 224.45 Restricted stock units released, vested (703,393 ) 201.85 Restricted stock units canceled (253,878 ) 179.71 Restricted stock units outstanding, December 31, 2014 1,403,974 114.56 Restricted stock units granted 711,990 236.89 Additional shares granted due to special distribution 51,432 297.03 Restricted stock units released, vested (623,554 ) 173.79 Special distribution shares released (19,966 ) 227.99 Restricted stock units canceled (103,922 ) 198.67 Special distribution shares canceled (3,516 ) 235.43 Restricted stock units outstanding, December 31, 2015 1,416,438 148.53 Restricted stock units granted 720,601 309.18 Additional shares granted due to special distribution 37 297.03 Restricted stock units released, vested (655,584 ) 213.72 Special distribution shares released (35,354 ) 269.94 Restricted stock units canceled (93,940 ) 242.41 Special distribution shares canceled (4,319 ) 272.84 Restricted stock units outstanding, December 31, 2016 1,347,879 192.59 1.2 $ 481,745 __________________________ (1) The intrinsic value is calculated based on the market value of the stock as of December 31, 2016 . The total fair value of restricted stock units vested and released during the years ended December 31, 2016 , 2015 and 2014 was $227,359,000 , $157,605,000 and $141,980,000 , respectively. Employee Stock Purchase Plan In June 2004, the Company’s stockholders approved the adoption of the 2004 Employee Stock Purchase Plan (the “2004 Purchase Plan”) as a successor plan to a previous plan that ceased activity in 2005. A total of 500,000 shares have been reserved for issuance under the 2004 Purchase Plan, and the number of shares available for issuance under the 2004 Purchase Plan automatically increased on January 1 each year, beginning in 2005 and ending in 2014 by the lesser of 2% of the shares of common stock then outstanding or 500,000 shares. Effective November 25, 2014, 3,197 shares were added to the 2004 Purchase Plan, representing an anti-dilutive adjustment pursuant to the 2014 Special Distribution. Effective November 10, 2015, 9,020 shares were added to the 2004 Purchase Plan, representing an anti-dilutive adjustment pursuant to the 2015 Special Distribution. As of December 31, 2016 , a total of 3,427,867 shares remained available for purchase under the 2004 Purchase Plan. The 2004 Purchase Plan permits eligible employees to purchase common stock on favorable terms via payroll deductions of up to 15% of the employee’s cash compensation, subject to certain share and statutory dollar limits. Two overlapping offering periods commence during each calendar year, on each February 15 and August 15 or such other periods or dates as determined by the Compensation Committee from time to time, and the offering periods last up to 24 months with a purchase date every six months. The price of each share purchased is 85% of the lower of a) the fair value per share of common stock on the last trading day before the commencement of the applicable offering period or b) the fair value per share of common stock on the purchase date. The 2004 Purchase Plan is administered by the Compensation Committee of the Board of Directors, and such plan will terminate automatically in June 2024 unless a) the 2004 Purchase Plan is extended by the Board of Directors and b) the extension is approved within 12 months by the Company’s stockholders. The Company provides the following disclosures for the 2004 Purchase Plan as of December 31 (dollars, except shares): 2016 2015 2014 Weighted-average purchase price per share $ 217.91 $ 150.13 $ 144.95 Weighted average grant-date fair value per share of shares purchased 60.49 57.63 53.37 Number of shares purchased 150,044 182,175 166,384 The Company uses the Black-Scholes option-pricing model to determine the fair value of shares purchased under the 2004 Purchase Plan with the following weighted average assumptions for the years ended December 31: 2016 2015 2014 Dividend yield 2.38-2.53% 2.65 - 2.81% 0 % Expected volatility 23 % 31 % 34 % Risk-free interest rate 0.36 % 0.26 % 0.19 % Expected life (in years) 1.04 1.25 1.25 Stock-Based Compensation Recognized in the Consolidated Statement of Operations The Company generally recognizes stock-based compensation expense on a straight-line basis over the requisite service period of the awards. However, for awards with market conditions or performance conditions, stock-based compensation expense is recognized on a straight-line basis over the requisite service period for each vesting tranche of the award. In October 2014, the Compensation Committee approved amendments to the terms of all outstanding restricted stock units (“RSUs”) granted prior to January 1, 2014 to provide for dividend equivalent rights (“DERs”) in the event of future dividends paid on the Company’s common stock. The Compensation Committee also approved an adjustment to outstanding stock options, including those under the Company’s Employee Stock Purchase Plan (“ESPP”), to ensure that the cash portion of the 2014 Special Distribution would not negatively impact the intrinsic value of the options. Pursuant to the accounting standard for stock compensation, these actions affecting the terms of the awards are considered modifications for accounting purposes that resulted in incremental stock-based compensation expenses and will be recognized over the requisite service period for each vesting tranche of the award. The total charges associated with this modification are insignificant to the financial statements. As of December 31, 2016 , the total stock-based compensation cost related to unvested equity awards not yet recognized, net of estimated forfeitures, totaled $241,037,000 which is expected to be recognized over a weighted-average period of 2.05 years. The following table presents, by operating expense, the Company’s stock-based compensation expense recognized in the Company’s consolidated statement of operations for the years ended December 31 (in thousands): 2016 2015 2014 Cost of revenues $ 13,086 $ 9,878 $ 8,511 Sales and marketing 43,030 36,847 30,084 General and administrative 100,032 86,908 79,395 Total $ 156,148 $ 133,633 $ 117,990 The Company’s stock-based compensation recognized in the consolidated statement of operations was comprised of the following types of equity awards for the years ended December 31 (in thousands): 2016 2015 2014 Stock options $ — $ 1,679 $ 4,917 Restricted shares and restricted stock units 145,769 124,512 104,235 Employee stock purchase plan 10,379 7,442 8,838 Total $ 156,148 $ 133,633 $ 117,990 Stock-based compensation for stock options for the year ended December 31, 2015 included $1,191,000 in as a result of the Company's acquisition of Bit-isle in November 2015. During the years ended December 31, 2016 , 2015 and 2014 , the Company capitalized $4,242,000 , $2,987,000 and $3,958,000 , respectively, of stock-based compensation expense as construction in progress in property, plant and equipment.

Income Taxes

Income Taxes	12 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company began operating as a real estate investment trust for federal income tax purposes ("REIT") effective January 1, 2015, and thereafter received a favorable private letter ruling (“PLR”) from the U.S. Internal Revenue Service (“IRS”) that validated the Company's position with respect to specified REIT compliance matters. As a result, the Company may deduct the distributions made to its stockholders 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”) in the U.S. will continue to be subject to federal and state 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. Income (loss) before income taxes is attributable to the following geographic locations for the years ended December 31, (in thousands): 2016 2015 2014 Domestic $ 215,010 $ 123,153 $ (46,876 ) Foreign (55,151 ) 87,845 131,609 Income from continuing operations before income taxes $ 159,859 $ 210,998 $ 84,733 The tax benefit (expenses) for income taxes consisted of the following components for the years ended December 31, (in thousands): 2016 2015 2014 Current: Federal $ (16,365 ) $ (85,352 ) $ (98,445 ) State and local (2,147 ) (3,984 ) (16,243 ) Foreign (62,278 ) (27,090 ) (31,844 ) Subtotal (80,790 ) (116,426 ) (146,532 ) Deferred: Federal (11,184 ) 87,801 (177,877 ) State and local (3,328 ) 4,600 (21,539 ) Foreign 49,851 801 489 Subtotal 35,339 93,202 (198,927 ) Provision for income taxes $ (45,451 ) $ (23,224 ) $ (345,459 ) State and foreign taxes not based on income are included in general and administrative expenses and the aggregate amounts were insignificant for the years ended December 31, 2016 , 2015 and 2014 . The Company is entitled to a deduction for federal and state income tax purposes with respect to employee equity award activity. The reduction in income tax payable related to windfall tax benefits for employee equity awards has been reflected as an adjustment to additional paid-in capital. For the years ended December 31, 2016 , 2015 and 2014 , the benefits arising from employee equity award activity that resulted in an adjustment to additional paid-in capital were approximately $2,773,000 , $30,000 and $18,561,000 , respectively. The amount of benefits for 2016 and 2015 is significantly lower than 2014 due to the zero effective U.S. tax rate that applies to the REIT as the Company intended to distribute or distributed 100% of its U.S. taxable income for 2016 and 2015. The fiscal 2016 , 2015 and 2014 income tax expense differed from the amounts computed by applying the U.S. federal income tax rate of 35% to pre-tax income as a result of the following for the years ended December 31 (in thousands): 2016 2015 2014 Federal tax at statutory rate $ (55,951 ) $ (73,849 ) $ (29,657 ) State and local taxes (4,895 ) 945 1,370 Deferred tax assets generated in current year not benefited (6,246 ) (4,916 ) (3,311 ) Foreign income tax rate differential 22,016 30,387 20,002 Non-deductible expenses (15,828 ) (14,252 ) (1,274 ) Stock-based compensation expense (5,890 ) (3,922 ) (4,496 ) Change in valuation allowance 11,995 710 1,655 Foreign financing activities (26,708 ) 2,592 2,981 Loss on debt extinguishment (8,288 ) — — Gain on divestments 8,828 — — Uncertain tax positions reserve (9,371 ) (3,191 ) (463 ) Tax adjustments related to REIT 45,060 45,823 (324,142 ) Other, net (173 ) (3,551 ) (8,124 ) Total income tax expense $ (45,451 ) $ (23,224 ) $ (345,459 ) The Company had not previously provided for deferred taxes on the excess of the financial reporting value over the tax basis in its investments in foreign subsidiaries that are essentially permanent in duration because the Company intended to reinvest the earnings outside the U.S. for an indefinite period of time. As a result of the Company’s conversion to a REIT effective January 1, 2015, it is no longer the Company’s intent to indefinitely reinvest undistributed foreign earnings from its operations in Europe, Canada and Japan. However, no deferred tax liability has been recognized to account for this change because the expected recovery of the basis difference will not result in taxes in the post-REIT conversion periods. As it continues to qualify as a REIT, the Company will not incur U.S. tax liability on the future repatriation of the foreign earnings and profits of the above noted jurisdictions due to the zero tax rate that will apply provided the Company distributes 100% of its taxable income. The Company, in general, will continue to reinvest its undistributed foreign earnings in jurisdictions that are not included in the REIT structure indefinitely. The foreign withholding taxes are expected to be immaterial if these undistributed foreign earnings are distributed. During the fourth quarter of 2016, the Company repatriated approximately $63,700,000 of foreign earnings from Singapore, which increased the taxable income for 2016 and was included in the REIT distribution for the year. There is no foreign withholding tax triggered by the repatriation. The types of temporary differences that give rise to significant portions of the Company’s deferred tax assets and liabilities are set out below as of December 31 (in thousands): 2016 2015 Deferred tax assets: Reserves and accruals $ 11,276 $ 13,013 Stock-based compensation expense 1,752 1,459 Unrealized (gains) losses — 10,656 Operating loss carryforwards 37,594 34,457 Others, net 5 18 Gross deferred tax assets 50,627 59,603 Valuation allowance (29,167 ) (29,894 ) Total deferred tax assets, net 21,460 29,709 Deferred tax liabilities: Property, plant and equipment (57,006 ) (9,048 ) Unrealized (gains) losses (7,832 ) — Intangible assets (168,655 ) (60,133 ) Total deferred tax liabilities (233,493 ) (69,181 ) Net deferred tax liabilities $ (212,033 ) $ (39,472 ) The tax basis of REIT assets, excluding investments in TRSs, is greater than the amounts reported for such assets in the accompanying consolidated balance sheet by approximately $1,153,900,000 at December 31, 2016 . The Company's accounting for deferred taxes involves weighing positive and negative evidence concerning the realizability of the Company's deferred tax assets in each tax jurisdiction. After considering such evidence as the nature, frequency and severity of current and cumulative financial reporting losses, and the sources of future taxable income and tax planning strategies, management concluded that valuation allowances were required in certain foreign jurisdictions. A valuation allowance continues to be provided for the deferred tax assets, net of deferred tax liabilities, associated with the Company's operations in Brazil, Canada, and certain jurisdictions located in the Company’s EMEA and Asia-Pacific regions. The operations in these jurisdictions have a history of significant losses as of December 31, 2016 . As such, management does not believe these operations have established a sustained history of profitability and that a valuation allowance is, therefore, necessary. Changes in the valuation allowance for deferred tax assets for the years ended December 31, 2016 , 2015 and 2014 are as follows (in thousands): 2016 2015 2014 Beginning balance $ 29,894 $ 27,181 $ 31,058 Amounts from acquisitions 5,053 — — Amounts recognized into income (11,995 ) (710 ) (1,655 ) Current increase (decrease) 6,557 4,513 721 Impact of foreign currency exchange (342 ) (1,090 ) (3,181 ) Net operating loss ("NOL") and tax credit expiration — — 238 Ending balance $ 29,167 $ 29,894 $ 27,181 Federal and state tax laws, including California tax laws, impose substantial restrictions on the utilization of NOL and credit carryforwards in the event of an "ownership change" for tax purposes, as defined in Section 382 of the Internal Revenue Code. In 2003, the Company conducted an analysis to determine whether an ownership change had occurred due to significant stock transactions in each of the reporting years disclosed at that time. The analysis indicated that an ownership change occurred during fiscal year 2002, which resulted in an annual limitation of approximately $819,000 for NOL carryforwards generated prior to 2003. Therefore, the Company substantially reduced its federal and state NOL carryforwards for the periods prior to 2003 to approximately $16,400,000. In addition, an ownership change under Section 382 of the Internal Revenue Code was triggered in September 2007 by the issuance of 4,211,939 shares of the Company's common stock. However, the annual limitation associated with this ownership change is not meaningful due to the substantial market capitalization of the Company at the time of the ownership change. The Company determined that no Section 382 ownership change occurred during the year ended December 31, 2016 . In addition, the NOL acquired in the Switch and Data acquisition in 2010 is subject to the Section 382 limitation; however, the Company has determined that none of the acquired NOLs will expire unused as a result of the limitation. The Company’s U.S. operations generated significant taxable income (versus book income) for the years ended December 31, 2016 and 2015 primarily due to the change in the tax method for depreciation of the Company’s property, plant and equipment. As the result of announcing its plan to pursue a REIT conversion, the Company changed its methods of depreciating and amortizing various data center assets to methods that are more consistent with the characterization of such assets as real property for REIT purposes. The change in the depreciation method resulted in the recapture of depreciation expense deducted in prior years and a much smaller amount of depreciation expense for the years ended December 31, 2016 and 2015. The Company’s NOL carryforwards for federal, state and foreign tax purposes which expire, if not utilized, at various intervals from 2017, are outlined below (in thousands): Expiration Date Federal (1) State (1) Foreign Total 2017 $ — $ — $ 9,018 $ 9,018 2018 to 2020 80,915 190 26,405 107,510 2021 to 2023 148,238 — 3,375 151,613 2024 to 2026 15,564 3,501 8,377 27,442 2027 to 2029 6,065 — — 6,065 2030 to 2032 — 2,445 — 2,445 Thereafter — 1,108 162,863 163,971 $ 250,782 $ 7,244 $ 210,038 $ 468,064 __________________________ (1) The total amount of NOL carryforwards that will not be available to offset the Company’s future taxable income after dividend paid deduction due to Section 382 limitations was $245,101,000 , comprising $241,766,000 of federal and $3,335,000 of state. Approximately $3,021,000 of the total NOL carryforwards is attributable to excess tax deductions related to employee equity awards, the benefit from which will be credited to additional paid-in capital when subsequently utilized in future years. The beginning and ending balances of the Company's unrecognized tax benefits are reconciled below for the years ended December 31 (in thousands): 2016 2015 2014 Beginning balance $ 30,845 $ 36,138 $ 36,552 Gross increases related to prior year tax positions 570 — 1,200 Gross decreases related to prior year tax positions — (8,645 ) (984 ) Gross increases related to current year tax positions 41,972 4,802 1,538 Decreases resulting from expiration of statute of limitation (826 ) (1,450 ) (1,112 ) Decreases resulting from settlements (374 ) — (1,056 ) Ending balance $ 72,187 $ 30,845 $ 36,138 The Company recognizes interest and penalties related to unrecognized tax benefits within income tax benefit (expense) in the consolidated statement of operations. During the year ended December 31, 2016 , the accrued interest and penalties related to the unrecognized tax benefits was increased by $675,000 . During the years ended December 31, 2015 and 2014 , the accrued interest and penalties related to the unrecognized tax benefits were decreased by $1,701,000 and $3,126,000 , respectively, primarily resulting from the settlement of tax audits and the lapse of statutes of limitations in its foreign operations. The Company has accrued $4,411,000 and $3,736,000 for interest and penalties accrued at December 31, 2016 and 2015 , respectively. The unrecognized tax benefits of $72,187,000 as of December 31, 2016 , if subsequently recognized, will affect the Company's effective tax rate favorably at the time when such a benefit is recognized. Due to various tax years open for examination, it is reasonably possible that the balance of unrecognized tax benefits could significantly increase or decrease over the next 12 months as the Company may be subject to either examination by tax authorities or a lapse in statute of limitations. The Company is currently unable to estimate the range of possible adjustments to the balance of unrecognized tax benefits. The Company's income tax returns for all tax years remain open to examination by federal and state taxing authorities due to the Company's NOL carryforwards. In addition, the Company's tax years of 2005 through 2015 remain open and subject to examination by local tax authorities in certain foreign jurisdictions in which the Company has major operations.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Commitments Primarily as a result of the Company’s various IBX expansion projects, as of December 31, 2016 , the Company was contractually committed for $234,365,000 of unaccrued capital expenditures, primarily for IBX equipment not yet delivered and labor not yet provided, in connection with the work necessary to open these IBX data centers and make them available to customers for installation. In addition, the Company had numerous other, non-capital purchase commitments in place as of December 31, 2016 , such as commitments to purchase power in select locations, primarily in select locations through 2017 and thereafter, and other open purchase orders for goods or services to be delivered or provided during 2017 and thereafter. Such other miscellaneous purchase commitments totaled $304,937,000 as of December 31, 2016 . Contingent Liabilities The Company estimates exposure on certain liabilities, such as indirect and property taxes, based on the best information available at the time of determination. With respect to real and personal property taxes, the Company records what it can reasonably estimate based on prior payment history, current landlord estimates or estimates based on current or changing fixed asset values in each specific municipality, as applicable. However, there are circumstances beyond the Company’s control whereby the underlying value of the property or basis for which the tax is calculated on the property may change, such as a landlord selling the underlying property of one of the Company’s IBX data center leases or a municipality changing the assessment value in a jurisdiction and, as a result, the Company’s property tax obligations may vary from period to period. Based upon the most current facts and circumstances, the Company makes the necessary property tax accruals for each of its reporting periods. However, revisions in the Company’s estimates of the potential or actual liability could materially impact the financial position, results of operations or cash flows of the Company. The Company's indirect and property tax filings in various jurisdictions are subject to examination by local tax authorities. The outcome of any examinations cannot be predicted with certainty. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations that would affect the adequacy of its tax accruals for each of the reporting periods. If any issues arising from the tax examinations are resolved in a manner inconsistent with the Company’s expectations, the revision of the estimates of the potential or actual liabilities could materially impact the financial position, results of operations, or cash flows of the Company. From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In the opinion of management, there are no pending claims for which the outcome is expected to result in a material adverse effect in the financial position, results of operations or cash flows of the Company. Employment Agreements The Company has entered into a severance agreement with each of its executive officers that provides for a severance payment equal to the executive officer’s annual base salary and maximum bonus in the event his or her employment is terminated for any reason other than cause or he or she voluntarily resigns under certain circumstances as described in the agreement. In addition, under the agreement, the executive officer is entitled to the payment of his or her monthly health care premiums under the Consolidated Omnibus Budget Reconciliation Act for up to 12 months. For certain executive officers, these benefits are only triggered after a change-in-control of the Company. Guarantor Arrangements As permitted under Delaware law, the Company has agreements whereby the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was serving, at the Company’s request in such capacity. The term of the indemnification period is for the officer's or director's lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits the Company’s exposure and enables the Company to recover a portion of any future amounts paid. As a result of the Company’s insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2016 . The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with any U.S. patent, or any copyright or other intellectual property infringement claim by any third party with respect to the Company’s offerings. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2016 . The Company enters into arrangements with its business partners, whereby the business partner agrees to provide services as a subcontractor for the Company’s installations. Accordingly, the Company enters into standard indemnification agreements with its customers, whereby the Company indemnifies them for other acts, such as personal property damage, of its subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has general and umbrella insurance policies that enable the Company to recover a portion of any amounts paid. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2016 . The Company has service level commitment obligations to certain of its customers. As a result, service interruptions or significant equipment damage in the Company’s IBX data centers, whether or not within the Company’s control, could result in service level commitments to these customers. The Company’s liability insurance may not be adequate to cover those expenses. In addition, any loss of services, equipment damage or inability to meet the Company’s service level commitment obligations could reduce the confidence of the Company’s customers and could consequently impair the Company’s ability to obtain and retain customers, which would adversely affect both the Company’s ability to generate revenues and the Company’s operating results. The Company generally has the ability to determine such service level credits prior to the associated revenue being recognized. The Company has no significant liabilities in connection with service level credits as of December 31, 2016 .

Quarterly Financial Information Disclosure [Abstract]
Quarterly Financial Information (Unaudited)	Quarterly Financial Information (Unaudited) The Company believes that period-to-period comparisons of its financial results should not be relied upon as an indication of future performance. The Company’s revenues and results of operations have been subject to significant fluctuations, particularly on a quarterly basis, and the Company’s revenues and results of operations could fluctuate significantly quarter-to-quarter and year-to-year. Significant quarterly fluctuations in revenues will cause fluctuations in the Company’s cash flows and the cash and cash equivalents and accounts receivable accounts on the Company’s consolidated balance sheet. Causes of such fluctuations may include the volume and timing of new orders and renewals, the timing of the opening of new IBX data centers, the sales cycle for the Company’s offerings, the introduction of new offerings, changes in prices and pricing models, trends in the internet infrastructure industry, general economic conditions, extraordinary events such as acquisitions or litigation and the occurrence of unexpected events. The unaudited quarterly financial information presented below has been prepared by the Company and reflects all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to present fairly the financial position and results of operations for the interim periods presented. The following tables present selected quarterly information (in thousands, except per share data): 2016 Quarters Ended March 31 June 30 September 30 December 31 Revenues $ 844,156 $ 900,510 $ 924,676 $ 942,647 Gross profit 416,476 443,543 454,374 476,726 Net income (loss) (31,111 ) 44,711 51,450 61,750 Comprehensive income (loss) 61,394 (182,521 ) (18,533 ) (173,623 ) EPS Basic EPS (0.46 ) 0.64 0.73 0.86 Diluted EPS (0.46 ) 0.64 0.72 0.86 2015 Quarters Ended March 31 June 30 September 30 December 31 Revenues $ 643,174 $ 665,582 $ 686,649 $ 730,462 Gross profit 344,861 349,825 361,181 378,494 Net income 76,452 59,459 41,132 10,731 Comprehensive income (loss) (59,141 ) 104,323 (23,707 ) (10,317 ) EPS Basic EPS 1.35 1.04 0.72 0.18 Diluted EPS 1.34 1.03 0.71 0.18

Nature of Business and Summar28

Nature of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation, Consolidation and Foreign Currency	Basis of Presentation, Consolidation and Foreign Currency The accompanying consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of the Paris IBX Data Center from August 1, 2016, TelecityGroup from January 15, 2016, Bit-isle from November 2, 2015 and Nimbo Technologies Inc. ("Nimbo") from January 14, 2015. All intercompany accounts and transactions have been eliminated in consolidation. Foreign exchange gains or losses resulting from foreign currency transactions, including intercompany foreign currency transactions, that are anticipated to be repaid within the foreseeable future, are reported within other income (expense) on the Company’s accompanying consolidated statements of operations. For additional information on the impact of foreign currencies to the Company’s consolidated financial statements, see “Accumulated Other Comprehensive Loss” in Note 12.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States ("U.S.") 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, fair values of financial instruments, intangible assets and goodwill, useful lives of intangible assets and property, plant and equipment, assets acquired and liabilities assumed from acquisitions, asset retirement obligations, restructuring charges, redemption value of redeemable non-controlling interests and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable.
Cash, Cash Equivalents and Short-Term and Long-Term Investments	Cash, Cash Equivalents and Short-Term and Long-Term Investments The Company considers all highly liquid instruments with an original maturity from the date of purchase of three months or less to be cash equivalents. Cash equivalents consist of money market mutual funds and highly liquid debt securities of corporations and certificates of deposit with original maturities up to 90 days. Short-term investments generally consist of debt securities with original maturities of between 90 days and one year. Long-term investments consist of debt securities with original maturities greater than 365 days and publicly traded equity securities. The Company’s fixed income securities and publicly traded equity securities are classified as “available-for-sale” and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income (loss). The cost of securities sold is based on the specific identification method. The Company reviews its investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades. Cash, Cash Equivalents and Investments. The fair value of the Company's investments in money market funds approximates their face value. Such instruments are included in cash equivalents. The Company’s money market funds and publicly traded equity securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices for identical instruments in active markets. The fair value of the Company's other investments approximate their face value and include certificates of deposit. The fair value of these investments is priced based on the quoted market price for similar instruments or nonbinding market prices that are corroborated by observable market data. Such instruments are classified within Level 2 of the fair value hierarchy. The Company determines the fair values of its Level 2 investments by using inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, custody bank, third-party pricing vendors, or other sources. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company is responsible for its consolidated financial statements and underlying estimates. The Company uses the specific identification method in computing realized gains and losses. Realized gains and losses on the investments are included within other income (expense) in the Company’s consolidated statements of operations. Short-term and long-term investments are classified as available-for-sale and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income or loss, net of any related tax effect. The Company reviews its investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades over an extended period of time.
Equity Method and Cost Method Investments	Equity Method and Cost Method Investments The Company's non-marketable securities are accounted under the cost method. The Company records the dividends declared by the investees in other income and expense in the consolidated statement of operations and records any dividends in excess of earnings as a reduction of cost of investment. The Company's other equity investments include private equity investments which are accounted under the equity method. The Company adjusts the carrying amount of an investment for its share of the earnings and losses of the investees and recognizes its share of income or loss in other income and expense in the consolidated statement of operations. The Company records cost method and equity method investments in other assets in the consolidated balance sheet. The Company reviews these investments periodically to determine if any investments may be other-than-temporarily impaired primarily based on the financial condition and near-term prospects of these companies and funds.
Financial Instruments and Concentration of Credit Risk	Financial Instruments and Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, short-term investments, long-term investments and accounts receivable. Risks associated with cash, cash equivalents, short-term investments and long-term investments are mitigated by the Company’s investment policy, which limits the Company’s investing to only those marketable securities rated at least A-1/P-1 Short Term Rating and A-/A3 Long Term Rating, as determined by independent credit rating agencies. Risk to the Company’s investment portfolio is further mitigated by its significant weighting in U.S. government securities in order to achieve REIT asset measure requirements. A significant portion of the Company’s customer base is comprised of businesses throughout the Americas. However, a portion of the Company’s revenues are derived from the Company’s EMEA and Asia-Pacific operations. The following table sets forth percentages of the Company’s revenues by geographic region for the years ended December 31: 2016 2015 2014 Americas 47 % 55 % 56 % EMEA 32 % 26 % 26 % Asia-Pacific 21 % 19 % 18 % No single customer accounted for greater than 10% of accounts receivable or revenues as of or for the years ended December 31, 2016, 2015 and 2014.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at the Company’s original cost or fair value for acquired property, plant and equipment. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements and integral equipment at leased locations are amortized over the shorter of the lease term or the estimated useful life of the asset or improvement. Leasehold improvements acquired in a business combination are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date of acquisition. Leasehold improvements that are placed into service significantly after and not contemplated at or near the beginning of the lease term are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date the leasehold improvements are purchased. The Company’s estimated useful lives of its property, plant and equipment are as follows: Core systems 3-25 years Buildings 12-50 years Leasehold improvements 12-40 years Construction in progress N/A Personal Property 3-10 years The Company’s construction in progress includes direct and indirect expenditures for the construction and expansion of IBX data centers and is stated at original cost. The Company has contracted out substantially all of the construction and expansion efforts of its IBX data centers to independent contractors under construction contracts. Construction in progress includes costs incurred under construction contracts including project management services, engineering and schematic design services, design development, construction services and other construction-related fees and services. In addition, the Company has capitalized interest costs during the construction phase. Once an IBX data center or expansion project becomes operational, these capitalized costs are allocated to certain property, plant and equipment categories and are depreciated over the estimated useful life of the underlying assets.
Asset Retirement Costs	Asset Retirement Costs The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred. The associated retirement costs are capitalized and included as part of the carrying value of the long-lived asset and amortized over the useful life of the asset. Subsequent to the initial measurement, the Company accretes the liability in relation to the asset retirement obligations over time and the accretion expense is recorded as a cost of revenue. The Company’s asset retirement obligations are primarily related to its IBX data centers, of which the majority are leased under long-term arrangements, and, in certain cases, are required to be returned to the landlords in their original condition. The majority of the Company’s IBX data center leases have been subject to significant development by the Company in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. The majority of the Company’s IBX data centers’ initial lease terms expire at various dates ranging from 2017 to 2065 and most of them enable the Company to extend the lease terms.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Company has three reportable segments comprised of the 1) Americas, 2) EMEA and 3) Asia-Pacific geographic regions, which the Company also determined are its reporting units. As of December 31, 2016, the Company had goodwill attributable to its Americas, EMEA and Asia-Pacific reporting units. The Company has the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test is unnecessary. However, if the Company concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test. The first step, identifying a potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step would need to be conducted; otherwise, no further steps are necessary as no potential impairment exists. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. In 2016, the Company elected to bypass the qualitative assessment and performed the first step of the two-step goodwill impairment test for its Americas, EMEA and Asia-Pacific reporting units during the quarter ended December 31, 2016. In order to determine the fair value of each reporting unit, the Company utilizes the discounted cash flow and market methods. The assumptions supporting the discounted cash flow method was determined using the Company’s best estimates as of the date of the impairment review. As of October 31, 2016, the Company concluded that it was more likely than not that goodwill attributed to the Company’s Americas, EMEA and Asia-Pacific reporting units was not impaired as the fair value of each reporting unit exceeded the carrying value of its respective reporting unit, including goodwill. In addition, the Company concluded that no events occurred or circumstances changed subsequent to October 31, 2016 through December 31, 2016 that would more likely than not reduce the fair value of the Americas, EMEA and Asia-Pacific reporting units below its carrying value. In 2015, the Company assessed qualitative and quantitative factors to determine whether it was more likely than not that the fair value of its Americas reporting unit, EMEA reporting unit and Asia-Pacific reporting unit was less than its carrying value and concluded that it was more likely than not that goodwill was not impaired. Impairment assessments inherently involve judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact the Company’s assumptions as to prices, costs, growth rates or other factors that may result in changes in the Company’s estimates of future cash flows. Although the Company believes the assumptions it used in its evaluation of impairment are reasonable, significant changes in any one of the Company’s assumptions could produce a significantly different result. Indicators of potential impairment that might lead the Company to perform interim goodwill impairment assessments include significant and unforeseen customer losses, a significant adverse change in legal factors or in the business climate, a significant adverse action or assessment by a regulator, a significant stock price decline or unanticipated competition. For further information on goodwill and other intangible assets, see Note 6 below.
Debt Issuance Costs	Debt Issuance Costs Loan fees and costs are capitalized and are amortized over the life of the related loans based on the effective interest method. Such amortization is included as a component of interest expense. Debt issuance costs related to outstanding debt are presented as a reduction of the carrying amount of the debt liability and debt issuance costs related to the revolving credit facility are presented as other assets. Debt issuance costs related to the unsecured bridge facility and undrawn Term B-2 Loan are presented as other current assets.
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company recognizes all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the value of a derivative depends on whether the contract is for trading purposes or has been designated and qualifies for hedge accounting. In order to qualify for hedge accounting, a derivative must be considered highly effective at reducing the risk associated with the exposure being hedged. In order for a derivative to be designated as a hedge, there must be documentation of the risk management objective and strategy, including identification of the hedging instrument, the hedged item and the risk exposure, and how effectiveness is to be assessed prospectively and retrospectively. Foreign currency gains or losses associated with derivatives that do not qualify for hedge accounting are recorded within other income (expense) in the Company’s consolidated statements of operations, with the exception of foreign currency embedded derivatives contained in certain of the Company’s customer contracts (see “Revenue Recognition” below), which are recorded within revenues in the Company’s consolidated statements of operations. To assess effectiveness of derivatives that qualify for hedge accounting, the Company uses a regression analysis. The extent to which a hedging instrument has been and is expected to continue to be effective at achieving offsetting changes in cash flows is assessed and documented at least quarterly. Any ineffectiveness is reported in current-period earnings. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued. For qualifying cash flow hedges, the effective portion of the change in the fair value of the derivative is recorded in other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged cash flows affect earnings. The ineffective portion of cash flow hedges is immediately recognized in earnings. If the hedge relationship is terminated, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the cash flows that were hedged occur, consistent with the original hedge strategy. For hedge relationships discontinued because the forecasted transaction is not expected to occur according to the original strategy, any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings. The Company does not use derivatives for speculative or trading purposes. For further information on derivatives and hedging activities, see Note 7 below. Derivative Assets and Liabilities . For derivatives, the Company uses forward contract and option models employing market observable inputs, such as spot currency rates and forward points with adjustments made to these values utilizing published credit default swap rates of its foreign exchange trading counterparties and other comparable companies. The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, therefore the derivatives are categorized as Level 2.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying value of the Company’s cash and cash equivalents, short-term and long-term investments represent their fair value, while the Company’s accounts receivable, accounts payable and accrued expenses and accrued property, plant and equipment approximate their fair value due primarily to the short-term maturity of the related instruments. The fair value of the Company’s debt, which is traded in the public debt market, is based on quoted market prices. The fair value of the Company’s debt, which is not publicly traded, is estimated by considering the Company’s credit rating, current rates available to the Company for debt of the same remaining maturities and terms of the debt. Fair Value Measurements The Company measures and reports certain financial assets and liabilities at fair value on a recurring basis, including its investments in money market funds and available-for-sale debt investments in other public companies, governmental units and other agencies, publicly traded equity securities and derivatives. The Company also follows the accounting standard for the measurement of fair value for non-financial assets and liabilities on a nonrecurring basis. These include: • Non-financial assets and non-financial liabilities initially measured at fair value in a business combination or other new basis event, but not measured at fair value in subsequent reporting periods; • Reporting units and non-financial assets and non-financial liabilities measured at fair value for goodwill impairment tests; • Indefinite-lived intangible assets measured at fair value for impairment assessments; • Non-financial long-lived assets or asset groups measured at fair value for impairment assessments or disposal; • Asset retirement obligations initially measured at fair value but not subsequently measured at fair value; and • Non-financial liabilities associated with exit or disposal activities initially measured at fair value but not subsequently measured at fair value. For further information on fair value measurements, see Note 8 below.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable such as a significant decrease in market price of a long-lived asset, a significant adverse change in legal factors or business climate that could affect the value of a long-lived asset or a continuous deterioration of the Company’s financial condition. Recoverability of assets to be held and used is assessed by comparing the carrying amount of an asset to estimated undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated discounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. The Company did not record any impairment charges related to its long-lived assets during the years ended December 31, 2016, 2015 and 2014.
Revenue Recognition	Revenue Recognition Equinix derives more than 90% of its revenues from recurring revenue streams, consisting primarily of (1) colocation, which includes the licensing of cabinet space and power; (2) interconnection offerings, such as cross connects and Equinix Exchange ports; (3) managed infrastructure services and (4) other revenues consisting of rental income from tenants or subtenants. The remainder of the Company’s revenues are from non-recurring revenue streams, such as installation revenues, professional services, contract settlements and equipment sales. Revenues from recurring revenue streams are generally billed monthly and recognized ratably over the term of the contract, generally one to three years for IBX data center colocation customers. Non-recurring installation fees, although generally paid in a lump sum upon installation, are deferred and recognized ratably over the period the customer is expected to benefit from the installation. Professional service fees are recognized in the period in which the services were provided and represent the culmination of a separate earnings process as long as they meet the criteria for separate recognition under the accounting standard related to revenue arrangements with multiple deliverables. Revenue from bandwidth and equipment sales is recognized on a gross basis in accordance with the accounting standard related to reporting revenue gross as a principal versus net as an agent, primarily because the Company acts as the principal in the transaction, takes title to products and services and bears inventory and credit risk. To the extent the Company does not meet the criteria for recognizing bandwidth and equipment services as gross revenue, the Company records the revenue on a net basis. Revenue from contract settlements, when a customer wishes to terminate their contract early, is generally recognized on a cash basis, when no remaining performance obligations exist, to the extent that the revenue has not previously been recognized. The Company guarantees certain service levels, such as uptime, as outlined in individual customer contracts. To the extent that these service levels are not achieved, the Company reduces revenue for any credits given to the customer as a result. The Company generally has the ability to determine such service level credits prior to the associated revenue being recognized, and historically, these credits have generally not been significant. There were no significant service level credits issued during the years ended December 31, 2016, 2015 and 2014. Revenue is recognized only when the service has been provided and when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the receivable is reasonably assured. It is the Company’s customary business practice to obtain a signed master sales agreement and sales order prior to recognizing revenue in an arrangement. Taxes collected from customers and remitted to governmental authorities are reported on a net basis and are excluded from revenue. As a result of certain customer agreements being priced in currencies different from the functional currencies of the parties involved, under applicable accounting rules, the Company is deemed to have foreign currency forward contracts embedded in these contracts. The Company refers to these as foreign currency embedded derivatives (see Note 7). These instruments are separated from their host contracts and held on the Company’s consolidated balance sheet at their fair value. The majority of these foreign currency embedded derivatives arise in certain of the Company’s subsidiaries where the local currency is the subsidiary’s functional currency and the customer contract is denominated in the U.S. dollar. Changes in their fair values are recognized within revenues in the Company’s consolidated statements of operations. The Company assesses collectability based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The Company generally does not request collateral from its customers although in certain cases the Company obtains a security interest in a customer’s equipment placed in its IBX data centers or obtains a deposit. If the Company determines that collection of a fee is not reasonably assured, the fee is deferred and revenue is recognized at the time collection becomes reasonably assured, which is generally upon receipt of cash. In addition, the Company also maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments for which the Company had expected to collect the revenues. If the financial condition of the Company’s customers were to deteriorate or if they became insolvent, resulting in an impairment of their ability to make payments, greater allowances for doubtful accounts may be required. Management specifically analyzes accounts receivable and current economic news and trends, historical bad debts, customer concentrations, customer credit-worthiness and changes in customer payment terms when evaluating revenue recognition and the adequacy of the Company’s reserves. Any amounts that were previously recognized as revenue and subsequently determined to be uncollectible are charged to bad debt expense included in general and administrative expense in the consolidated statements of operations. A specific bad debt reserve of up to the full amount of a particular invoice value is provided for certain problematic customer balances. An additional reserve is established for all other accounts based on the age of the invoices and an analysis of historical credits issued. Delinquent account balances are written-off after management has determined that the likelihood of collection is not probable.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are expected more likely than not to be realized in the future. A tax benefit from an uncertain income tax position may be recognized in the financial statements only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. The Company began operating as a REIT for federal income tax purposes effective January 1, 2015, and thereafter received a favorable private letter ruling (“PLR”) from the U.S. Internal Revenue Service (“IRS”) that validated the Company's position with respect to specified REIT compliance matters. As a result, the Company may deduct the distributions made to its stockholders from taxable income generated by the Company's Qualified REIT Subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the U.S. taxable income of the Company's 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 TRS. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax benefit (expense) in the consolidated statements of operations.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation cost is measured at the grant date for all stock-based awards made to employees and directors based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period. The Company grants restricted stock units to its employees and these equity awards generally have only a service condition. The Company grants restricted stock units to its executives and these awards generally have a service and performance condition or a service and market condition. To date, any performance conditions contained in an equity award are tied to the financial performance of the Company or a specific region of the Company. The Company assesses the probability of meeting these performance conditions on a quarterly basis. The majority of the Company’s equity awards vest over four years, although certain of the equity awards for executives vest over a range of two to four 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 uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition. The Company uses the Black-Scholes option-pricing model to determine the fair value of its employee stock purchase plan. The determination of the fair value of shares purchased under the employee stock purchase plan is affected by assumptions regarding a number of complex and subjective variables including the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock purchase behaviors. The Company estimated the expected volatility by using the average historical volatility of its common stock that it believed was best representative of future volatility. The risk-free interest rate used was based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term of the equity awards. The expected dividend rate used in 2015 and thereafter was based on average dividend yields and the expected dividend rate used prior to 2015 was zero as the Company did not anticipate paying dividends. The expected term used was equal to the term of each purchase window. The accounting standard for stock-based compensation does not allow the recognition of unrealized tax benefits associated with the tax deductions in excess of the compensation recorded (excess tax benefit) until the excess tax benefit is realized (i.e., reduces taxes payable). The Company recognizes the benefit from stock-based compensation in equity when the excess tax benefit is realized by following the “with-and-without” approach. For further information on stock-based compensation, see Note 13 below.
Foreign Currency Translation	Foreign Currency Translation The financial position of foreign subsidiaries is translated using the exchange rates in effect at the end of the period, while income and expense items are translated at average rates of exchange during the period. Gains or losses from translation of foreign operations where the local currency is the functional currency are included as other comprehensive income (loss). The net gains and losses resulting from foreign currency transactions are recorded in net income (loss) in the period incurred and reported within other income and expense. Certain inter-company balances are designated as long-term. Accordingly, exchange gains and losses associated with these long-term inter-company balances are recorded as a component of other comprehensive income (loss), along with translation adjustments.
Earnings Per Share	Earnings Per Share The Company computes basic and diluted EPS for net income (loss) attributable to the Company. Basic EPS is computed using net income (loss) attributable to the Company and the weighted-average number of common shares outstanding. Diluted EPS is computed using net income attributable to the Company, adjusted for interest expense as a result of the assumed conversion of the Company’s 3.00% Convertible Subordinated Notes and 4.75% Convertible Subordinated Notes, if dilutive, and the weighted-average number of common shares outstanding plus any dilutive potential common shares outstanding. Dilutive potential common shares include the assumed exercise, vesting and issuance activity of employee equity awards using the treasury stock method, as well as shares issuable upon the assumed conversion of the 3.00% Convertible Subordinated Notes and 4.75% Convertible Subordinated Notes. See Note 3 below.
Redeemable Non-Controlling Interests	Redeemable Non-Controlling Interests Non-controlling interests in subsidiaries that are redeemable for cash or other assets outside of the Company’s control are classified as mezzanine equity, outside of equity and liabilities, and are adjusted to fair value on each balance sheet date. The resulting changes in fair value of the estimated redemption amount, increases or decreases, are recorded with corresponding adjustments against retained earnings or, in the absence of retained earnings, additional paid-in-capital For further information on redeemable non-controlling interests, see Note 11 below.
Treasury Stock	Treasury Stock The Company accounts for treasury stock under the cost method. When treasury stock is re-issued at a higher price than its cost, the difference is recorded as a component of additional paid-in capital to the extent that there are gains to offset the losses. If there are no treasury stock gains in additional paid-in capital, the losses are recorded as a component of retained earnings (accumulated deficit).
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In January 2017, Financial Accounting Standards Board ("FASB") has issued Accounting Standards Update ("ASU") No. 2017-04 Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU is to simplify the subsequent measurement of goodwill. The ASU eliminates step 2 from the goodwill impairment test and the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU should be applied on a prospective basis. This ASU is effective for public business entities for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company currently does not expect to early adopt this ASU. In January 2017, FASB has issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, clarifying the definition of a business. The ASU affects all companies and other reporting organizations that must determine whether they have acquired or sold a business. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In December 2016, FASB has issued ASU No. 2016-19, Technical Corrections and Improvements. This ASU covers a wide range of Topics in the Accounting Standards Codification. This ASU is effective for public business entities for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years with early adoption is permitted. The Company does not expect this ASU to impact its consolidated financial statements. In November 2016, FASB has issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU applies to all entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows. The ASU requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years with early adoption is permitted. This ASU should be applied using a retrospective transition method to each period presented. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. Adoption of this standard eliminates the effect of changes in restricted cash from investing activities in the presentation of the Consolidated Statement of Cash Flows and does not affect the Consolidated Statements of Operations or Consolidated Balance Sheets. I n October 2016, FASB has issued ASU No. 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control. This ASU alters how a decision maker needs to consider indirect interests in a variable interest entity ("VIE") held through an entity under common control. Under this ASU, if a decision maker is required to evaluate whether it is the primary beneficiary of a VIE, it will need to consider only its proportionate indirect interest in the VIE held through a common control party. This ASU is effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years, with early adoption permitted. The Company does not expect this ASU to impact its consolidated financial statements as it does not hold any interests in a VIE through related parties that are under common control. In October 2016, FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This ASU requires the recognition of the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU is effective for fiscal years and interim period within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements but does not expect to early adopt this ASU. In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU provides guidance on the classification of eight cash flow issues to reduce the existing diversification in practice, including (a) debt prepayment or debt extinguishment costs; (b) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (c) contingent consideration payments made after a business combination; (d) proceeds from settlement of insurance claims; (e) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (f) distributions received from equity method investees; (g) beneficial interests in securitization transactions; and (h) separately identifiable cash flows and application of the predominance principle. The ASU is effective for fiscal years and interim period within those fiscal years, beginning after December 15, 2017, 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 June 2016, FASB issued 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 expects this ASU to impact its accounts receivable and is currently evaluating the extent of the impact that the adoption of this ASU 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. Some of the Company’s debt instruments contain contingent options that can accelerate the payment of principal. The Company does not expect that its embedded derivative conclusions will change on adoption of this ASU. The Company will complete its assessment on the impact that the adoption of this ASU will have on its consolidated financial statements by the effective date. 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 will adopt this ASU prospectively in the first quarter of 2017 and does not expect that adoption of this standard to impact its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). The new guidance requires lessees to recognize the following for leases with terms of more than 12 months: (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 includes a number of optional practical expedients that we may elect to apply. 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 to 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 currently holds publicly traded equity securities that are classified as “available-for-sale” and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income (loss). On adoption of this ASU, the unrealized gains and losses will be recognized through net income. The Company has not elected to measure its financial liabilities at fair value therefore, does not expect an impact on the accounting for its financial liabilities. 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 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively (ASU 2014-09, ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-11, ASU 2016-12 and ASU 2016-20 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 allows entities to adopt with one of these two methods: full retrospective, which applies retrospectively to each prior reporting periods presented or modified retrospective, which recognizes the cumulative effect of initially applying the revenue standard as an adjustment to the opening balance of retained earnings in the period of initial application. The Company currently anticipates adopting the standard using the modified retrospective method. 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 expects to adopt the standard on January 1, 2018. While the Company is continuing to evaluate all potential impacts of the standard, the Company believes the most significant impact relates to its accounting for installation revenue and the cost to obtain contracts. Under the new standard, the Company expects to recognize installation revenue over the contract period rather than over the estimated installation life. Under the new standard, the Company is required to capitalize and amortize certain costs to obtain contracts. Therefore, these costs to obtain contracts will not be immediately expensed, but will be capitalized and amortized over the estimated contract term plus estimated renewal term. 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. Adjustments to provisional amounts for the TelecityGroup acquisition are discussed in Note 2 Acquisitions. 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 VIEs or voting interest entities; (2) the ASU eliminates the presumption that a general partner should consolidate limited partnership; (3) the ASU affects the consolidation analysis of reporting entities that 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.
Fair Value Valuation Methods	Valuation Methods Fair value estimates are made as of a specific point in time based on methods using the market approach valuation method which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities or other valuation techniques. These techniques involve uncertainties and are affected by the assumptions used and the judgments made regarding risk characteristics of various financial instruments, discount rates, estimates of future cash flows, future expected loss experience and other factors.
Segment Information	While the Company has a single line of business, which is the design, build-out and operation of IBX data centers, it has determined that it has three reportable segments comprised of its Americas, EMEA and Asia-Pacific geographic regions. The Company’s chief operating decision-maker evaluates performance, makes operating decisions and allocates resources based on the Company’s revenues and adjusted EBITDA performance both on a consolidated basis and these three reportable segments.
