Basis of Presentation, Consolidation and Foreign Currency The accompanying consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of: • Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands from April 18, 2019; • Metronode from the Ontario Teachers' Pension Plan Board (the "Metronode Acquisition") from April 18, 2018; • Infomart Dallas, including its operations and tenants, from ASB Real Estate Investments (the "Infomart Dallas Acquisition") from April 2, 2018; • Itconic, a data center business in Spain and Portugal from October 9, 2017; • Zenium's data center business in Istanbul from October 6, 2017; • certain colocation business from Verizon Communications Inc. ("Verizon") consisting of 29 data center buildings located in the United States ("U.S."), Brazil and Colombia (the "Verizon Data Center Acquisition") from May 1, 2017; • IO UK's data center operating business in Slough, United Kingdom ("IO Acquisition") from February 3, 2017. 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 the accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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, and assets acquired and liabilities assumed from acquisitions, useful lives of intangible assets and property, plant and equipment, leases, asset retirement obligations, other accruals, 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 Investments The Company considers all highly liquid instruments with an original maturity from the date of purchase of 90 days or less to be cash equivalents. Cash equivalents consist of money market mutual funds and certificates of deposit with original maturities up to 90 days. Short-term investments generally consist of certificates of deposit with original maturities of between 90 days and 1 year. Publicly traded equity securities are measured at fair value with changes in the fair values recognized within other income (expense) in the Company's consolidated statements of operations. 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 Investments The Company enters into joint venture or partnership arrangements to invest in certain entities for business development objectives. At the inception of these arrangements, the Company assesses its interests with other entities to determine whether any of such entities meet the definition of a variable interest entity ("VIE"). A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support, or (ii) has equity investors who lack the characteristics of a controlling financial interest. The Company is required to consolidate the assets and liabilities of VIEs when it is deemed to be the primary beneficiary. The primary beneficiary of a VIE is the entity that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. As of December 31, 2019, the Company concluded that it did not have any significant investments in entities that are deemed to be VIEs. The Company’s investments in joint ventures and partnerships are generally accounted for under the equity method of accounting, as the Company concluded it does not have control, but has the ability to exercise significant influence over the investees. Equity method investments are initially measured at cost, or at fair value for a retained investment in the common stock of an investee in a deconsolidation transaction. Equity investments are subsequently adjusted for cash contributions, distributions and the Company's share of the income and losses of the investees. The Company records its equity method investments in other assets in the consolidated balance sheet. The Company's proportionate share of the income or loss from its equity method investments are recorded in other income in the consolidated statement of operations. The Company reviews its investments periodically to determine if any investments may be impaired considering both qualitative and quantitative factors that may have a significant impact on the investees' fair value. The Company did no t record any impairment charges related to its equity method investments for the years ended December 31, 2019, 2018 and 2017. Non-marketable Equity Investments The Company also has investments in non-marketable equity securities, where the Company does not have the ability to exercise significant influence over the investees. The Company elected the measurement alternative under which the securities are measured at cost minus impairment, if any, and adjusted for changes resulting from qualifying observable price changes. The Company records non-marketable equity investment in other assets in the consolidated balance sheet. The Company reviews its non-marketable equity investments quarterly to determine if any investments may be impaired considering both qualitative and quantitative factors that may have a significant impact on the investees' fair value. The Company did no t record any impairment charges related to its non-marketable equity investments for the years ended December 31, 2019, 2018 and 2017. Financial Instruments and Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. Risks associated with cash and cash equivalents and short-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 or A-/A3 Long Term Rating, as determined by independent credit rating agencies. 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: 2019 2018 2017 Americas 47 % 49 % 50 % EMEA 32 % 31 % 31 % Asia-Pacific 21 % 20 % 19 % No single customer accounted for greater than 10% of accounts receivable or revenues as of or for the years ended December 31, 2019 , 2018 and 2017 . Property, Plant and Equipment Property, plant and equipment are stated at the Company's original cost or at fair value for property, plant and equipment acquired through acquisitions, net of depreciation. 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 through acquisition are amortized over the shorter of the useful life of the assets or terms that include 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 3-40 years Buildings 12-58 years Leasehold improvements 12-40 years 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. The Company reviews its property, plant and equipment 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 an asset, a significant adverse change in the extent or manner in which an asset is being used or in its physical condition, a significant adverse change in legal factors or business climate that could affect the value of an 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 undiscounted 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 property, plant and equipment during the years ended December 31, 2019, 2018 and 2017. The Company enters into non-cancellable lease arrangements as the lessee primarily for its data center spaces, office spaces and equipment. Assets acquired through finance leases are included in property, plant and equipment, net on the consolidated balance sheets. In addition, a portion of the Company's property, plant and equipment are used for revenue arrangements which are accounted for as operating leases where the Company is the lessor. Assets Held for Sale Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale are reported at the lower of their carrying amounts or fair values less costs to sell. The Company recorded an impairment charge of $15.8 million relating to assets held for sale for the year ended December 31, 2019. Assets are not depreciated or amortized while they are classified as held for sale. For further information on the Company's assets held for sale, see Note 5. Asset Retirement Costs and Asset Retirement Obligations 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 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. For further information on the Company's leases, see Note 10. 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. Goodwill is not amortized and is tested for impairment at least annually or more often if and when circumstances indicate that goodwill is not recoverable. The Company assesses 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. Qualitative factors considered in the assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting the reporting unit. 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 a quantitative impairment test is unnecessary. However, if the Company concludes otherwise, then it is required to perform a quantitative goodwill impairment test. The quantitative impairment test, which is used to identify both the existence of impairment and the amount of impairment loss, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying value of the reporting unit exceeds its fair value, any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. As of December 31, 2019, 2018 and 2017, 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. Substantially all of the Company's intangible assets are subject to amortization and are amortized using the straight-line method over their estimated period of benefit. The Company performs a review of intangible assets for impairment by assessing events or changes in circumstances that indicate the carrying amount of an asset may not be recoverable. 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 undiscounted 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 other intangible assets during the years ended December 31, 2019 , 2018 and 2017 . For further information on goodwill and other intangible assets, see Note 3 and Note 7 below. Debt Issuance Costs Costs and fees incurred upon debt issuances are capitalized and are amortized over the life of the related debt 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 obligation and debt issuance costs related to the revolving credit facility are presented as other assets. Derivatives and Hedging Activities The Company uses derivative instruments, including foreign currency forwards and options and cross-currency interest rate swaps, to manage certain foreign currency exposures. Derivative instruments are viewed as risk management tools by the Company and are not used for speculative purposes. The Company recognizes all derivatives on the Company's consolidated balance sheets at fair value. The accounting for changes in the value of a derivative depends on whether the contract qualifies and has been designated 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 and 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 the effectiveness assessment methodology. For cash flow hedges, the Company uses regression analysis at the time they are designated to assess their effectiveness. Hedge designations are reviewed on a quarterly basis to assess whether circumstances have changed that would disrupt the hedge instrument's relationship to the forecasted transactions or net investment. The Company uses the forward method to assess effectiveness of qualifying foreign currency forwards that are designated as cash flow hedges, whereby, the change in the fair value of the derivative is recorded in other comprehensive income (loss) and reclassified to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item when the hedged item affects earnings. The Company uses the spot method to assess effectiveness of qualifying foreign currency exchange options that are designated as cash flow hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and reclassified to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item when the hedged item affects earnings, and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized on a straight-line basis to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item. When two or more derivative instruments in combination are jointly designated as a cash flow hedging instrument, as with foreign currency exchange option collars, they are treated as a single instrument. If the hedge relationship is terminated for any derivatives designated as cash flow hedges, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the previously hedged item affects earnings, consistent with the original hedge strategy. For hedge relationships that are discontinued because the forecasted transaction is not expected to occur according to the original strategy, then any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings. From time to time, the Company enters into treasury lock agreements to add stability to interest expense and to manage its exposure to interest rate movements. A treasury lock is a synthetic forward sale of a U.S. treasury note which is settled in cash based upon the difference between an agreed upon treasury rate and the prevailing treasury rate at settlement. It is entered into to effectively fix the treasury rate component of an upcoming debt issuance. The treasury lock transactions are designated as cash flow hedges, with all changes in value reported in other comprehensive income (loss). Subsequent to settlement, amounts in other comprehensive income are reclassified to interest expense as interest payments are accrued on the debt. The Company uses the spot method to assess effectiveness of cross-currency interest rate swaps that are designated as net investment hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized to interest expense on a straight-line basis. From time to time, the Company also uses 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. The Company uses the spot method to assess effectiveness of qualifying foreign currency forwards that are designated as net investment hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized to interest expense on a straight-line basis. Foreign currency gains or losses associated with derivatives that are not designated as hedging instruments for accounting purposes are recorded within other income (expense) in the Company's condensed consolidated statements of operations, with the exception of (i) foreign currency embedded derivatives contained in certain of the Company's customer contracts and (ii) foreign exchange forward contracts that are entered into to hedge the accounting impact of the foreign currency embedded derivatives, which are recorded within revenues in the Company's condensed consolidated statements of operations. For further information on derivatives and hedging activities, see Note 8 below. Fair Value of Financial Instruments The carrying value of the Company's cash and cash equivalents, short-term investments and derivative instruments 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, certificates of deposit, 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; and • Asset retirement obligations initially measured at fair value but not subsequently measured at fair value. For further information on fair value measurements, see Note 9 below. Leases The Company determines if an arrangement is or contains a lease at its inception. The Company enters into lease arrangements primarily for data center spaces, office spaces and equipment. The Company recognizes a right-of-use ("ROU") asset and lease liability on the consolidated balance sheet for all leases with a term longer than 12 months, including renewals. ROU assets represent the Company's right to use an underlying asset for the lease term. Lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are classified and recognized at the commencement date. ROU liabilities are measured based on the present value of fixed lease payments over the lease term. ROU assets consist of (i) initial measurement of the lease liability; (ii) lease payments made to the lessor at or before the commencement date less any lease incentives received; and (iii) initial direct costs incurred by the Company. Lease payments may vary because of changes in facts or circumstances occurring after the commencement, including changes in inflation indices. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate) are included in the measurement of ROU assets and lease liabilities using the index or rate at the commencement date. Variable lease payments that do not depend on an index or a rate are excluded from the measurement of ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. Since most of the Company's leases do not provide an implicit rate, the Company uses its own incremental borrowing rate ("IBR") on a collateralized basis in determining the present value of lease payments. The Company utilizes a market-based approach to estimate the IBR. The approach requires significant judgment. Therefore, the Company utilizes different data sets to estimate IBRs via an analysis of (i) yields on comparable credit rating composite curves; (ii) sovereign rates; (iii) yields on our outstanding public debt; and (iv) historical difference in yields on the curves of our secured and unsecured rated debt. The Company also applies adjustments to account for considerations related to (i) tenor; and (ii) country credit rating that may not be fully incorporated by the aforementioned data sets. The majority of the Company's lease arrangements include options to extend the lease. If the Company is reasonably certain to exercise such options, the periods covered by the options are included in the lease term. The depreciable lives of certain fixed assets and leasehold improvements are limited by the expected lease term. The Company has certain leases with an initial term of 12 months or less. For such leases, the Company elected not to recognize any ROU asset or lease liability on the consolidated balance sheet. The Company has lease agreements with lease and non-lease components. The Company elected to account for the lease and non-lease components as a single lease component for all classes of underlying assets for which the Company has identified lease arrangements. Revenue 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 solutions 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 by service lines and geographic areas are included in segment information (see Note 17). Under the revenue accounting guidance, revenues are recognized when control of these products and services is transferred to its customers, in an amount that reflects the consideration it expects to be entitled to in exchange for the products and services. Revenues from recurring revenue streams are generally billed monthly and recognized ratably over the term of the contract, generally 1 to 3 years for IBX data center colocation customers. Non-recurring installation fees, although generally paid upfront upon installation, are deferred and recognized ratably over the contract term. Professional service fees and equipment sales are recognized in the period when the services were provided. For the contracts with customers that contain multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct or as a series of distinct obligations if the individual performance obligations meet the series criteria. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The transaction price is allocated to the separate performance obligation on a relative standalone selling price basis. The standalone selling price is determined based on overall pricing objectives, taking into consideration market conditions, geographic locations and other factors. Other judgments include determining if any variable consideration should be included in the total contract value of the arrangement such as price increases. Revenue is generally recognized on a gross basis as a principal versus on a net basis as an agent, as the Company is primarily responsible for fulfilling the contract, bears inventory risk and has discretion in establishing the price when selling to the customer. To the extent the Company does not meet the criteria for recognizing revenue on a gross basis, the Company records the revenue on a net basis. Revenue from contract settlements, when a customer wishes to terminate their contract early, is treated as a contract modification and recognized ratably over the remaining term of the contract, if any. The Company guarantees certain service levels, such as uptime, as outlined in individual customer contracts. If these service levels are not achieved due to any failure of the physical infrastructure or offerings, or in the event of certain instances of damage to customer infrastructure within the Company's IBX data centers, the Company would reduce revenue for any credits or cash payments given to the customer. Historically, these credits and cash payments have not been significant. The Company enters into revenue contracts with customers for data centers and office spaces, which contain both lease and non-lease components. The Company elected to adopt the practical expedient which allows lessors to combine lease and non-lease components, by underlying class of asset, and account for them as one component if they have the same timing and pattern of transfer. The combined component is accounted for in accordance with the current lease accounting guidance ("Topic 842") if the lease component is predominant, and in accordance with the current revenue accounting guidance ("Topic 606") if the non-lease compon

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Contract Balances The following table summarizes the opening and closing balances of the Company's accounts receivable, net; contract asset, current; contract asset, non-current; deferred revenue, current; and deferred revenue, non-current (in thousands): Accounts receivable, net Contract asset, current Contract asset, non-current Deferred revenue, current Deferred revenue, non-current Beginning balances as of January 1, 2019 $ 630,119 $ 9,778 $ 16,396 $ 73,143 $ 46,641 Closing balances as of December 31, 2019 689,134 10,033 31,521 76,193 46,555 Increase/(decrease) $ 59,015 $ 255 $ 15,125 $ 3,050 $ (86 ) Beginning balances as of January 1, 2018 (1) $ 576,313 $ 9,002 $ 16,186 $ 71,085 $ 53,101 Closing balances as of December 31, 2018 630,119 9,778 16,396 73,143 46,641 Increase/(decrease) $ 53,806 $ 776 $ 210 $ 2,058 $ (6,460 ) (1) Includes cumulative adjustments made to these accounts on January 1, 2018 from the adoption of Topic 606. The difference between the opening and closing balances of the Company's accounts receivable, net, contract assets and deferred revenues primarily results from the timing difference between the satisfaction of the Company's performance obligation and the customer's payment, as well as business combinations closed during the years ended December 31, 2019 and 2018. The amounts of revenue recognized during the years ended December 31, 2019 and 2018 from the opening deferred revenue balance were approximately $87.3 million and $81.8 million , respectively. For the years ended December 31, 2019 and 2018, no impairment loss related to contract balances was recognized in the consolidated statement of operations. Contract Costs The ending balances of net capitalized contract costs as of December 31, 2019 and 2018 were $229.2 million and $188.2 million , respectively, which were included in other assets in the consolidated balance sheet. $72.9 million and $73.1 million of contract costs were amortized during years ended December 31, 2019 and 2018, respectively, which were included in sales and marketing expense in the consolidated statement of operations. Remaining performance obligations As of December 31, 2019 , approximately $7.4 billion of total revenues and deferred installation revenues are expected to be recognized in future periods, the majority of which will be recognized over the next 24 months . While initial contract terms vary in length, substantially all contracts thereafter automatically renew in one-year increments. Included in the remaining performance obligations is either 1) remaining performance obligations under the initial contract terms or 2) remaining performance obligations related to contracts in the renewal period once the initial terms have lapsed. The remaining performance obligations do not include variable consideration related to unsatisfied performance obligations such as the usage of metered power, service fees from xScale data centers, which are calculated based on future events or actual costs incurred in the future, or any contracts that could be terminated without any significant penalties such as the majority of interconnection revenues. The remaining performance obligations above include revenues to be recognized in the future related to arrangements where the Company is considered the lessor.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions 2019 Acquisitions On April 18, 2019, the Company completed the acquisition of Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands, for a cash purchase price of approximately €30.6 million or approximately $34.3 million , at the exchange rate in effect on April 18, 2019. As of September 30, 2019, the Company had completed the detailed valuation analysis to derive the fair value of assets acquired and liabilities assumed and updated the final allocation of purchase price. The operating results of the acquisition were reported in the EMEA region following the date of acquisition and were not significant to the Company's total operations for the year ended December 31, 2019. 2018 Acquisitions On April 18, 2018, the Company acquired all of the equity interests in Metronode from the Ontario Teachers' Pension Plan Board for a cash purchase price of A$1.034 billion , or approximately $804.6 million at the exchange rate in effect on April 18, 2018. Metronode operated 10 data centers in six metro areas in Australia. The acquisition supports the Company's ongoing global expansion to meet customer demand in the Asia-Pacific region. On April 2, 2018, the Company completed the acquisition of Infomart Dallas, including its operations and tenants, from ASB Real Estate Investments, for total consideration of approximately $804.0 million . The consideration was comprised of approximately $45.8 million in cash, subject to customary adjustments and $758.2 million aggregate fair value of 5.000% senior unsecured notes. Prior to the acquisition, a portion of the building was leased to the Company and was being used as its Dallas 1, 2, 3 and 6 data centers, which were all accounted for as build-to-suit leases. Upon acquisition, the Company effectively terminated the leases and settled the related financing obligations and other liabilities related to the leases for approximately $170.3 million and $1.9 million , respectively, and recognized a loss on debt extinguishment of $19.5 million . The acquisition of this highly interconnected facility and tenants adds to the Company's global platform and secures the ability to further expand in the Americas market in the future. Both acquisitions constitute a business under the accounting standard for business combinations and, therefore, were accounted for as business combinations using the acquisition method of accounting. 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. During the three months ended March 31, 2019, the Company completed the detailed valuation analysis of Metronode and Infomart Dallas to derive the fair value of assets acquired and liabilities assumed and finalized the allocation of purchase price for Metronode and Infomart Dallas. For the Metronode Acquisition, the adjustments made during the three months ended March 31, 2019 primarily resulted in a decrease in deferred tax liability and goodwill of $4.2 million and $3.7 million , respectively. No purchase price allocation adjustments were made during the three months ended March 31, 2019 for the Infomart Dallas Acquisition. For the Metronode Acquisition, the adjustments made from the provisional amounts reported as of June 30, 2018 primarily resulted in a decrease in property, plant and equipment, other assets, other liabilities and deferred tax assets of $10.1 million , $10.0 million , $9.7 million and $4.1 million , respectively, and an increase in goodwill, intangible assets and deferred tax liabilities of $41.6 million , $4.8 million and $31.3 million , respectively. The adjustments for the Infomart Dallas Acquisition made from the provisional amounts reported as of June 30, 2018 primarily resulted in a decrease in goodwill of $6.2 million and an increase in intangible assets of $4.6 million . The changes in fair value of acquired assets and liabilities assumed did not have a significant impact on the Company's results of operations for any reporting periods prior to March 31, 2019. A summary of the final allocation of total purchase consideration is presented as follows (in thousands): Metronode Infomart Dallas Cash and cash equivalents $ 3,206 $ 17,432 Accounts receivable 8,318 637 Other current assets 9,421 395 Property, plant and equipment 297,092 362,023 Intangible assets 128,229 65,847 Goodwill 410,188 197,378 Other assets (1) 44,373 — Total assets acquired 900,827 643,712 Accounts payable and accrued liabilities (17,104 ) (5,056 ) Other current liabilities (2,038 ) (2,141 ) Deferred tax liabilities (31,281 ) — Other liabilities (1) (45,851 ) (4,723 ) Net assets acquired $ 804,553 $ 631,792 (1) In connection with the Metronode Acquisition, the Company recorded indemnification assets of $44.4 million , which represented the seller's obligation under the purchase agreement to reimburse pre-acquisition tax liabilities settled after the acquisition. The following table presents certain information on the acquired intangible assets (in thousands): Intangible Assets Fair Value Estimated Useful Lives (Years) Weighted-average Estimated Useful Lives (Years) Customer relationships (Metronode) $ 128,229 20.0 20.0 Customer relationships (Infomart Dallas) 35,860 20.0 20.0 In-place leases (Infomart Dallas) 19,960 3.6 - 7.5 6.8 Trade names (Infomart Dallas) 9,552 20.0 20.0 Favorable leases (Infomart Dallas) 475 3.6 - 7.5 7.0 The fair value of customer relationships was estimated by applying an income approach, by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The Company applied discount rates of 7.3% for Metronode and 8.2% for Infomart Dallas, which reflected the nature of the assets as they relate to the risk and uncertainty of the estimated future operating cash flows. Other assumptions used to estimate the fair value of customer relationships included projected revenue growth, capital expenditures, probability of renewal, customer attrition rates and operating margins. The fair value of Infomart Dallas' trade name was estimated using the relief from royalty method under the income approach. The Company applied a relief from royalty rate of 1.5% and a discount rate of 8.2% . The fair value of in-place leases was estimated by projecting the avoided costs, such as the cost of originating the acquired in-place leases, during a typical lease up period. 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 property, plant and equipment was estimated by applying the cost approach, with the exception of land, which was estimated by applying the market approach, for the Metronode Acquisition. For the Infomart Dallas Acquisition, the fair values of land, building and personal property were estimated by applying the market approach, residual income method and cost approach, respectively. The cost approach uses 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 new, physical deterioration, functional and economic obsolescence, economic useful life, remaining useful life, age and effective age. The residual income method estimates the fair value of the Infomart Dallas building using an income approach less the fair values attributed to land, personal property, in-place leases and favorable and unfavorable leases. Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired and liabilities assumed. Goodwill is attributable to the workforce of the acquired business and the projected revenue increase expected to arise from future customers after the Metronode and Infomart Dallas acquisitions. Goodwill from the acquisition of Metronode is not amortizable for local tax purposes and is attributable to the Company's Asia-Pacific region. Goodwill from the acquisition of Infomart Dallas is expected to be deductible for local tax purposes and is attributable to the Company's Americas region. Operating results of Metronode and Infomart Dallas have been reported in the Asia-Pacific and Americas regions, respectively. The Company incurred transaction costs of approximately $31.1 million during the year ended December 31, 2018 for both acquisitions. The Company's results of operations include $78.7 million of revenues and an insignificant amount of net income from operations from the combined operations of Metronode and Infomart Dallas during the year ended December 31, 2018. Certain Verizon Data Center Assets Acquisition On May 1, 2017, the Company completed the acquisition of certain colocation business from Verizon consisting of 29 data center buildings located in the United States, Brazil and Colombia, for a cash purchase price of approximately $3.6 billion . The addition of these facilities and customers adds to the Company's global platform, increases interconnections and assists with the Company's penetration of the enterprise and strategic markets, including government and energy. The Company funded the Verizon Data Center Acquisition with proceeds from debt and equity financings, which closed in January and March 2017. Purchase Price Allocation The Verizon Data Center Acquisition constitutes a business under the accounting standard for business combinations and, therefore, was accounted for as a business combination using the acquisition method of accounting. During the three months ended March 31, 2018, the Company had completed the detailed valuation analysis to derive the fair value of assets acquired and liabilities assumed and updated the final allocation of purchase price from provisional amounts reported as of June 30, 2017, which primarily resulted in a decrease in intangible assets of $9.0 million and an increase in goodwill of $7.7 million . The changes in fair value of acquired assets and liabilities assumed did not have a significant impact on the Company's results of operations for any reporting periods prior to and including December 31, 2018. The final purchase price allocation is as follows (in thousands): Certain Verizon Data Center Assets Cash and cash equivalents $ 1,073 Accounts receivable 2,019 Other current assets 7,319 Property, plant and equipment 840,335 Intangible assets (1) 1,693,900 Goodwill 1,095,262 Total assets acquired 3,639,908 Accounts payable and accrued liabilities (1,725 ) Other current liabilities (2,020 ) Capital lease and other financing obligations (17,659 ) Deferred tax liabilities (18,129 ) Other liabilities (5,689 ) Net assets acquired $ 3,594,686 (1) The nature of the intangible assets acquired is customer relationships with an estimated useful life of 15 years. Included in this amount is a customer relationship intangible asset for Verizon totaling $245.3 million . Pursuant to the acquisition agreement, the Company formalized agreements to provide pre-existing space and services to Verizon at the acquired data centers. The fair value of customer relationships was estimated by applying an income approach. The Company applied discount rates ranging from 7.7% to 12.2% , which reflected the nature of the assets as they relate to the risk and uncertainty of the estimated future operating cash flows. Other assumptions used to estimate the fair value of customer relationships include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. 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 property, plant and equipment was estimated by applying the cost approach, with the exception of land which was estimated by applying the market approach. The cost approach is to use the replacement or reproduction cost as an indicator of fair value. The 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. Goodwill is attributable to the workforce of the acquired business and the projected revenue increase expected to arise from future customers after the Verizon Data Center Acquisition. Goodwill is deductible for U.S. tax purposes and is attributable to the Company's Americas region.

The acquisition includes five data centers in four metro areas, with two located in Madrid and one each in Barcelona, Seville and Lisbon. Itconic's operating results have been reported in the EMEA region following the date of acquisition. The nature of the intangible assets acquired from the Itconic acquisition is customer relationships with an estimated useful life of 15 years . The fair value of customer relationships was estimated by applying an income approach. The Company applied a discount rate of 16.0% , which reflects the risk and uncertainty of the estimated future operating cash flows. Other assumptions include projected revenue growth, customer attrition rates and operating margins. 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.

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 the value of investments in its 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 debt obligations, which are designated as hedges against the Company's net investments in foreign subsidiaries. As of December 31, 2019 and 2018 , the total principal amounts of foreign currency debt obligations designated as net investment hedges were $4,078.7 million and $4,139.8 million , respectively. The Company also uses cross-currency interest rate swaps to hedge a portion of its net investment in its European operations. As of December 31, 2019 , U.S. Dollar to Euro cross-currency interest rate swap contracts with a total notional amount of $750.0 million were outstanding, with maturity dates in April 2022, January 2024 and January 2025. At maturity of each outstanding contract, the Company will receive U.S. Dollars from and pay Euros to the contract counterparty. During the term of each contract, the Company receives interest payments in U.S. Dollars and makes interest payments in Euros based on a notional amount and fixed interest rates determined at contract inception. The Company did not have any cross-currency interest rate swaps outstanding as of December 31, 2018 . The effect of net investment hedges on accumulated other comprehensive income and the consolidated statements of operations for the years ended December 31, 2019 , 2018 and 2017 was as follows (in thousands): Amount of gain or (loss) recognized in accumulated other comprehensive income: Years Ended December 31, 2019 2018 2017 Foreign currency debt $ 47,033 $ 218,269 $ (235,292 ) Cross-currency interest rate swaps (included component) (1) 15,514 — — Cross-currency interest rate swaps (excluded component) (2) 10,737 — — Total $ 73,284 $ 218,269 $ (235,292 ) Amount of gain or (loss) recognized in earnings: Location of gain or (loss) Years Ended December 31, 2019 2018 2017 Cross-currency interest rate swaps (excluded component) (2) Interest expense $ 19,261 $ — $ — Total $ 19,261 $ — $ — (1) Included component represents foreign exchange spot rates. (2) Excluded component represents cross-currency basis spread and interest rates. 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, Swedish Krona and Swiss Franc. The foreign currency forward and option contracts that the Company uses to hedge this exposure are designated as cash flow hedges. As of December 31, 2019 and 2018 , the total notional amounts of these foreign exchange contracts were $824.8 million and $760.9 million , respectively. The Company hedges the interest rate exposure created by anticipated fixed rate debt issuances through the use of treasury locks, which are designated as cash flow hedges. During the fourth quarter of 2019, we entered into and settled ten treasury locks designated as cash flow hedges with an aggregate notional amount of $1.5 billion , hedging anticipated fixed-rate debt issuances. The settlement of these contracts during the fourth quarter of 2019, resulted in a gain of $5.1 million , which was deferred and included as a component of other comprehensive income (loss), and is being amortized to interest expense over the life of the associated debt. The Company enters into intercompany hedging instruments ("intercompany derivatives") with wholly-owned subsidiaries 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 effect of cash flow hedges on accumulated other comprehensive income and the consolidated statements of operations for the years ended December 31, 2019 , 2018 and 2017 was as follows (in thousands): Amount of gain or (loss) recognized in accumulated other comprehensive income: Years Ended December 31, 2019 2018 2017 Foreign currency forward and option contracts (included component) (1) $ (9,945 ) $ 58,227 $ (73,437 ) Foreign currency option contracts (excluded component) (2) (1,807 ) — — Treasury locks 4,972 — — Total $ (6,780 ) $ 58,227 $ (73,437 ) Amount of gain or (loss) reclassified from accumulated other comprehensive income to income: Years Ended December 31, Location of gain or (loss) 2019 2018 2017 Foreign currency forward contracts Revenues $ 80,046 $ (30,603 ) $ 20,845 Foreign currency forward contracts Costs and operating expenses (41,262 ) 15,341 (11,183 ) Treasury locks Interest Expense 79 — — Total $ 38,863 $ (15,262 ) $ 9,662 Amount of gain or (loss) excluded from effectiveness testing and included in income: Years Ended December 31, Location of gain or (loss) 2019 2018 2017 Foreign currency forward contracts Other income (expense) $ 88 $ 16,470 $ 3,805 Foreign currency option contracts (excluded component) (2) Revenues (1,082 ) — — Total $ (994 ) $ 16,470 $ 3,805 (1) Included component represents foreign exchange spot rates. (2) Excluded component represents option's time value. As of December 31, 2019 , the Company's foreign currency cash flow hedge instruments had maturity dates ranging from January 2020 to December 2021 and the Company recorded a net gain of $16.3 million within accumulated other comprehensive income (loss) relating to cash flow hedges that will be reclassified to revenues and expenses as they mature in the next 12 months. As of December 31, 2018 , the Company's foreign currency cash flow hedge instruments had maturity dates ranging from January 2019 to December 2020 and the Company recorded a net gain of $21.4 million within accumulated other comprehensive income (loss) relating to cash flow hedges that will be reclassified to revenues and expenses as they mature in the next 12 months. As of December 31, 2019 , the Company had no interest rate cash flow hedges outstanding. The net gain in accumulated other comprehensive income (loss) to be reclassified to interest expense in the next 12 months for settled interest rate cash flow hedges is $0.7 million . 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 U.S. Dollars. Economic Hedges of Embedded Derivatives . The Company uses foreign currency forward contracts to manage the foreign exchange risk associated with the Company's customer agreements that are priced in currencies different from the functional or local currencies of the parties involved ("economic hedges of embedded derivatives"). Foreign currency forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. Foreign Currency Forward Contracts . The Company also uses foreign currency forward contracts to manage the foreign exchange risk associated with certain foreign currency-denominated monetary assets and liabilities. As a result of foreign currency fluctuations, the U.S. Dollar equivalent values of its foreign currency-denominated monetary assets and liabilities change. Gains and losses on these contracts are included in other income (expense), on a net basis, along with the foreign currency gains and losses of the related foreign currency-denominated monetary assets and liabilities associated with these foreign currency forward contracts. As of December 31, 2019 and 2018 , the total notional amounts of these foreign currency contracts were $2,467.0 million and $1,500.4 million , respectively.

(2) As presented in the Company's condensed consolidated balance sheets within other current liabilities and other liabilities. Offsetting Derivative Assets and Liabilities The Company presents its derivative instruments and the accrued interest related to cross-currency interest rate swaps at gross fair values in the condensed consolidated balance sheets. The Company enters into master netting agreements with its counterparties for transactions other than embedded derivatives to mitigate credit risk exposure to any single counterparty. Master netting agreements allow for individual derivative contracts with a single counterparty to offset in the event of default. For presentation on the consolidated balance sheets, the Company does not offset fair value amounts recognized for derivative instruments or the accrued interest related to cross-currency interest rate swaps under master netting arrangements. The following table presents information related to these offsetting arrangements as of December 31, 2019 and 2018 (in thousands): Gross Amounts Offset in Consolidated Balance Sheet Gross Amounts Gross Amounts Offset in the Balance Sheet Net Amounts Gross Amounts not Offset in the Balance Sheet Net December 31, 2019 Derivative assets $ 76,640 $ — $ 76,640 $ (37,820 ) $ 38,820 Derivative liabilities 45,832 — 45,832 (37,820 ) 8,012 December 31, 2018 Derivative assets $ 73,074 $ — $ 73,074 $ (6,517 ) $ 66,557 Derivative liabilities 9,740 — 9,740 (6,517 ) 3,223

Fair Value Measurements

Fair Value Measurements	12 Months Ended

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 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, including certificates of deposit, approximates their face value. 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 from the sale of investments are included within other income (expense) in the Company's consolidated statements of operations. The Company's investments in publicly traded equity securities are carried at fair value. Subsequent to the adoption of ASU 2016-01, unrealized gains and losses on publicly traded equity securities are reported within other income (expense) in the Company's consolidated statements of operations. Prior to the adoption of ASU 2016-01, unrealized gains and losses on publicly traded equity securities were reported in stockholders' equity as a component of other comprehensive income or loss. Upon adoption of ASU 2016-01, the Company recorded a net cumulative effect increase of $2.1 million to retained earnings. Derivative Assets and Liabilities . Inputs used for valuations of derivatives are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data. The significant inputs used include spot currency rates and forward points, interest rate curves, and 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, 2019 and 2018 , 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, 2019 were as follows (in thousands): Fair Value at December 31, Fair Value Measurement Using 2019 Level 1 Level 2 Assets: Money market and deposit accounts $ 886,547 $ 886,547 $ — Publicly traded equity securities 2,779 2,779 — Certificates of deposit 7,583 — 7,583 Derivative instruments 57,707 — 57,707 $ 954,616 $ 889,326 $ 65,290 Liabilities: Derivative instruments $ 35,612 $ — $ 35,612 The Company's financial assets and liabilities measured at fair value on a recurring basis at December 31, 2018 were as follows (in thousands): Fair Value at December 31, Fair Value Measurement Using 2018 Level 1 Level 2 Assets: Money market and deposit accounts $ 119,518 $ 119,518 $ — Publicly traded equity securities 1,717 1,717 — Certificates of deposit 2,823 — 2,823 Derivative instruments 73,074 — 73,074 $ 197,132 $ 121,235 $ 75,897 Liabilities: Derivative instruments $ 9,740 $ — $ 9,740 The Company did not have any Level 3 financial assets or financial liabilities during the years ended December 31, 2019 and 2018 .

Leases [Abstract]
Leases	Leases Significant Lease Transactions Hong Kong 4 ("HK4") Data Center In August 2018, the Company entered into a lease agreement with the landlord to lease the remaining floors of the HK4 Data Center. The lease did not commence until May 2019. The lease has an initial term of 9.4 years and one 10 -year renewal option which the Company determined it was not reasonably certain to exercise. The Company therefore excluded the renewal option from the lease term. The Company assessed the lease classification of the HK4 lease at the commencement date and determined the lease should be accounted for as an operating lease. During the three months ended June 30, 2019, the Company recorded operating lease ROU asset and liability of 317.3 million Hong Kong dollars, or $40.6 million at the exchange rate in effect on June 30, 2019. Seoul 1 ("SL1") Data Center In October 2018, the Company entered into a lease agreement with the landlord for several leased spaces in SL1 Data Center. Phase 1 commenced in August 2019 with an initial term of 5 years . The lease includes three 5 -year renewal options. The Company concluded that one renewal option of 5 years is reasonably certain to be exercised after considering all relevant factors that create an economic incentive for the Company. The Company assessed the lease classification of the SL1 lease at the commencement date and determined the lease should be accounted for as a finance lease. During the three months ended September 30, 2019, the Company recorded finance lease ROU asset and liability of 35,747 million Korean Won and 34,804 million Korean Won, respectively, or $29.9 million and $29.1 million , respectively, at the exchange rate in effect on September 30, 2019. Tokyo 11 ("TY11") Data Center In July 2019, the Company entered into two new lease agreements for building I and building II in TY11 Data Center for a lease term of 28.6 years . At the same time, the Company terminated the original lease agreement of certain leased space in building I. The new spaces in building I and building II provide additional right-of-use assets that are not included in the original lease agreement and the lease payments for the new spaces are commensurate with the stand-alone price of the additional right-of-use assets. As a result, the Company concluded the new spaces in building I and building II met the criteria to be treated as a separate contract and did not modify the accounting treatment of the original leased space. The Company assessed the lease classification of TY11 leases at the commencement date and determined that the leases for both the new spaces in building I and building II should be accounted for as finance leases. During the three months ended September 30, 2019, the Company recorded finance lease ROU asset and liability of ¥6,922.3 million in aggregate for both new spaces in building I and II, or approximately $64.0 million at the exchange rate in effect on September 30, 2019. Singapore 4 ("SG4") Data Center In July 2019, the Company entered into a lease agreement with the landlord to lease the land and building for its new SG4 Data Center. The initial lease term is 25 years with a renewal option to extend the lease until 2053 .

For the year ended December 31, 2018 and 2017, the Company sold 930,934 shares and 763,201 shares, respectively, for approximately $388.2 million and $355.1 million , respectively, net of payment of commissions to the sales agents and estimated equity offering costs. As of December 31, 2018, no shares remained available for sale under the 2017 ATM Program. In December 2018, the Company established another ATM program, under which it may, from time to time, offer and sell up to an aggregate of $750.0 million of its common stock to or through sales agents in "at the market" transactions (the "2018 ATM Program"). For the year ended December 31, 2019 , the Company sold 903,555 shares for approximately $447.5 million , net of payment of commissions to sales agents and other offering expenses, under the 2018 ATM Program. As of December 31, 2019 , the Company had reserved the following authorized but unissued shares of common stock for future issuances: Common stock options and restricted stock units 3,334,130 Common stock employee purchase plans 2,973,785 Total 6,307,915 Accumulated Other Comprehensive Loss The changes in accumulated other comprehensive loss, net of tax, by components are as follows (in thousands): December 31, 2016 Net December 31, 2017 Net Cumulative Effect Adjustment December 31, 2018 Net December 31, 2019 Foreign currency translation adjustment ("CTA") gain (loss) $ (1,031,129 ) $ 454,269 $ (576,860 ) $ (421,743 ) $ — $ (998,603 ) $ (58,315 ) $ (1,056,918 ) Unrealized gain (loss) on cash flow hedges (1) 30,704 (54,895 ) (24,191 ) 43,671 — 19,480 (3,842 ) 15,638 Net investment hedge CTA gain (loss) (1) 49,989 (235,292 ) (185,303 ) 219,628 — 34,325 73,294 107,619 Unrealized gain (loss) on available for sale securities (2) 2,110 14 2,124 — (2,124 ) — — — Net actuarial gain (loss) on defined benefit plans (3) (816 ) (143 ) (959 ) 55 — (904 ) (48 ) (952 ) $ (949,142 ) $ 163,953 $ (785,189 ) $ (158,389 ) $ (2,124 ) $ (945,702 ) $ 11,089 $ (934,613 ) (1) Refer to Note 8 for a discussion of the amounts reclassified from accumulated other comprehensive loss to net income. (2) Upon adoption of ASU 2016-01 during the three months ended March 31, 2018, the Company recorded a net cumulative effect adjustment of $2.1 million from accumulated other comprehensive loss to retained earnings. The realized gains and losses reclassified from accumulated other comprehensive loss to net income as a result of sale of available for sale securities were not significant for the years ended December 31, 2017 and 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. 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 loss), as well as its consolidated results of operations, as amounts in foreign currencies are generally translated into more U.S. dollars when the U.S. dollar weakens or less U.S. dollars when the U.S. dollar strengthens. As of December 31, 2019 , the U.S. dollar was generally stronger relative to certain of the currencies of the foreign countries in which the Company operates as compared to December 31, 2018 . This overall strengthening 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 the increase in foreign currency translation loss for the year ended December 31, 2019 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. Dividends During the years ended December 31, 2019 , 2018 and 2017 , the Company's Board of Directors declared quarterly dividends whose treatment for federal income tax purposes were as follows: Declaration Date Record Date Payment Date Total Distribution (1) Nonqualified Ordinary Dividend (2) Total Distribution Amount (per share) (in thousands) Fiscal 2019 2/13/2019 2/27/2019 3/20/2019 $ 2.460000 $ 2.460000 $ 198,933 5/1/2019 5/22/2019 6/19/2019 2.460000 2.460000 207,949 7/31/2019 8/21/2019 9/18/2019 2.460000 2.460000 209,226 10/30/2019 11/20/2019 12/11/2019 2.460000 2.460000 209,785 Total $ 9.840000 $ 9.840000 $ 825,893 Fiscal 2018 2/14/2018 2/26/2018 3/21/2018 $ 2.280000 $ 2.280000 $ 180,640 5/2/2018 5/23/2018 6/20/2018 2.280000 2.280000 181,207 8/8/2018 8/22/2018 9/19/2018 2.280000 2.280000 182,304 11/1/2018 11/14/2018 12/12/2018 2.280000 2.280000 183,297 Total $ 9.120000 $ 9.120000 $ 727,448 Fiscal 2017 2/15/2017 2/27/2017 3/22/2017 $ 2.000000 $ 2.000000 $ 143,275 4/26/2017 5/24/2017 6/21/2017 2.000000 2.000000 155,824 8/2/2017 8/23/2017 9/20/2017 2.000000 2.000000 156,055 11/1/2017 11/15/2017 12/13/2017 2.000000 2.000000 156,931 Total $ 8.000000 $ 8.000000 $ 612,085 (1) Common stock dividends are characterized for federal income tax purposes as nonqualified ordinary dividend, qualified ordinary dividend, capital gains or return of capital. During the years ended December 31, 2019 , 2018 and 2017 , the Company did not classify any portion of the distributions as qualified ordinary dividend, capital gains or return of capital. (2) All 2019 and 2018 nonqualified ordinary dividends are eligible for the 20% deduction generally allowable to non-corporate shareholders under Internal Revenue Code Section 199A. In addition, as of December 31, 2019 , for dividends and special distributions attributed to the restricted stock units, the Company recorded a short term dividend payable of $9.0 million and a long term dividend payable of $7.1 million for the restricted stock units that have not yet vested. As of December 31, 2018 , for dividends and special distributions attributed to the restricted stock units, the Company recorded a short term dividend payable of $8.8 million and a long term dividend payable of $6.5 million for the restricted stock units that have not yet vested.

The Equity compensation plans are administered by the Compensation Committee of the Board of Directors (the "Compensation Committee"), and the Compensation Committee may terminate or amend these plans, with approval of the stockholders as may be required by applicable law, at any time. As of December 31, 2019 , shares reserved and available for issuance under the equity compensation plans are as follows: Shares reserved Shares available for grant 2000 Equity Incentive Plan 16,636,172 1,255,261 2000 Director Option Plan 594,403 505,646 2001 Supplemental Stock Plan 1,494,275 260,498 2004 Purchase Plan 5,392,206 2,973,785 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, 2016 1,347,879 $ 192.59 Restricted stock units granted 658,196 389.60 Restricted stock units released, vested (606,064 ) 260.75 Special distribution shares released (15,667 ) 243.06 Restricted stock units canceled (79,451 ) 313.83 Special distribution shares canceled (1,002 ) 282.49 Restricted stock units outstanding, December 31, 2017 1,303,891 252.30 Restricted stock units granted 704,249 387.31 Restricted stock units released, vested (593,528 ) 299.07 Special distribution shares released (13,880 ) 283.14 Restricted stock units canceled (173,460 ) 336.75 Special distribution shares canceled (485 ) 295.77 Restricted stock units outstanding, December 31, 2018 1,226,787 361.22 Restricted stock units granted 779,478 448.16 Restricted stock units released, vested (549,259 ) 362.66 Special distribution shares released (1,781 ) 295.31 Restricted stock units canceled (142,477 ) 364.42 Special distribution shares canceled (23 ) 297.04 Restricted stock units outstanding, December 31, 2019 1,312,725 $ 411.99 1.29 $ 766,238 (1) The intrinsic value is calculated based on the market value of the stock as of December 31, 2019 . The total fair value of restricted stock units vested and released during the years ended December 31, 2019 , 2018 and 2017 was $269.1 million , $249.8 million and $259.1 million , respectively.

Income Taxes	Income Taxes Income (loss) before income taxes is attributable to the following geographic locations for the years ended December 31, (in thousands): 2019 2018 2017 Domestic $ 328,806 $ 298,009 $ 148,500 Foreign 363,791 135,029 138,332 Income before income taxes $ 692,597 $ 433,038 $ 286,832 The tax benefit (expenses) for income taxes consisted of the following components for the years ended December 31, (in thousands): 2019 2018 2017 Current: Federal $ (17,906 ) $ 7,085 $ 9,346 State and local (4,624 ) (2,663 ) (849 ) Foreign (135,356 ) (118,175 ) (109,032 ) Subtotal (157,886 ) (113,753 ) (100,535 ) Deferred: Federal (7,459 ) (27,874 ) 9,684 State and local (1,775 ) (1,165 ) 2,018 Foreign (18,232 ) 75,113 34,983 Subtotal (27,466 ) 46,074 46,685 Income tax expense $ (185,352 ) $ (67,679 ) $ (53,850 ) State and foreign taxes not based on income are included in general and administrative expenses and the aggregate amounts were not significant for the years ended December 31, 2019 , 2018 and 2017 . The fiscal 2019 , 2018 , and 2017 income tax benefit (expenses) differed from the amounts computed by applying the U.S. federal income tax rate of 21% , 21% and 35% , respectively, to pre-tax income as a result of the following for the years ended December 31 (in thousands): 2019 2018 2017 Federal tax at statutory rate $ (145,445 ) $ (90,938 ) $ (100,391 ) State and local tax (expense) benefit (5,852 ) (3,616 ) 1,000 Deferred tax assets generated in current year not benefited (5,398 ) (3,777 ) (7,643 ) Foreign income tax rate differential (11,610 ) (4,072 ) 26,151 Non-deductible expenses (1,021 ) (756 ) (2,629 ) Stock-based compensation expense (2,105 ) (2,308 ) (616 ) Change in valuation allowance (2,870 ) 38,684 (716 ) Foreign financing activities (18,738 ) (17,548 ) 1,319 Loss on debt extinguishment — — (1,604 ) Loss on divestments (3,277 ) — — Uncertain tax positions reserve (35,724 ) (20,440 ) (66 ) Tax adjustments related to REIT 63,614 32,189 41,973 Enactment of the US tax reform — — (6,513 ) Change in deferred tax adjustments (10,574 ) — — Other, net (6,352 ) 4,903 (4,115 ) Total income tax expense $ (185,352 ) $ (67,679 ) $ (53,850 ) Legislation commonly referred to as the Tax Cuts and Jobs Act ("TCJA"), which was signed into law on December 22, 2017, contained many significant changes to the U.S. federal income tax laws. Among other things, the TCJA reduced the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018, limited the tax deductibility of interest expense, accelerated expensing of certain business assets and transitioned the U.S. international taxation from a worldwide tax system to a territorial tax system by imposing a one-time mandatory repatriation of undistributed foreign earnings. As a result of the reduced corporate tax rate, the Company recognized an income tax expense of $6.5 million during the fourth quarter of 2017 as a provisional estimate due to the remeasurement of the net deferred tax assets in the U.S. TRS. In the fourth quarter of 2018, the Company completed the analysis of the TCJA's income tax effects and the adjustment to the provisional amount was insignificant. The TCJA included a Global Intangible Low-Taxed Income ("GILTI") provision that increases U.S. federal taxable income by certain foreign subsidiary income in the year it is earned. The Company's accounting policy is to treat any tax on GILTI inclusions as a current period cost included in the tax expense in the year incurred. The Company believes the GILTI inclusion provision will result in no financial statement impact provided the Company satisfies its REIT distribution requirement with respect to the GILTI inclusions. 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. 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 U.S. taxes in the post-REIT conversion periods due to the fact that none of its foreign subsidiaries is owned by a U.S. taxable REIT subsidiary and the withholding tax effect would be immaterial. The Company continues to assess the foreign withholding tax impact of its current policy and does not believe the distribution of its foreign earnings would trigger any significant foreign withholding taxes, as a majority of the foreign jurisdictions where the Company operates do not impose withholding taxes on dividend distributions to a corporate U.S. parent. 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): 2019 2018 Deferred tax assets: Reserves and accruals $ 7,670 $ 24,136 Stock-based compensation expense 2,675 2,524 Unrealized losses 6,492 1,471 Operating loss carryforwards 59,735 49,169 Gross deferred tax assets 76,572 77,300 Valuation allowance (57,812 ) (57,003 ) Total deferred tax assets, net 18,760 20,297 Deferred tax liabilities: Property, plant and equipment (85,729 ) (50,610 ) Intangible assets (144,404 ) (159,237 ) Total deferred tax liabilities (230,133 ) (209,847 ) Net deferred tax liabilities $ (211,373 ) $ (189,550 ) 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 $1.9 billion as of December 31, 2019 . 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, the Company concluded that valuation allowances were required in certain foreign jurisdictions. The operations in the jurisdictions for which a valuation allowance has been established have a history of significant losses as of December 31, 2019 . As such, the Company does not believe these operations have established a sustained history of profitability and that a valuation allowance is, therefore, necessary. The Company also provided a valuation allowance against certain gross deferred tax assets in certain tax jurisdictions as these deferred tax assets are not expected to be realizable in the foreseeable future. Changes in the valuation allowance for deferred tax assets for the years ended December 31, 2019 , 2018 and 2017 are as follows (in thousands): 2019 2018 2017 Beginning balance $ 57,003 $ 84,573 $ 29,167 Amounts from acquisitions (2,707 ) 33,070 25,283 Divested balances (351 ) — — Amounts recognized into income 2,870 (38,684 ) 716 Current increase (decrease) 697 (13,086 ) 28,431 Impact of foreign currency exchange 300 (8,870 ) 976 Ending balance $ 57,812 $ 57,003 $ 84,573 The Company's NOL carryforwards for federal, state and foreign tax purposes which expire, if not utilized, at various intervals from 2020 , are outlined below (in thousands): Expiration Date Federal (1) State Foreign (2) (3) Total 2020 $ 78,458 $ — $ 9,739 $ 88,197 2021 to 2023 149,057 — 6,191 155,248 2024 to 2026 15,564 — 19,867 35,431 2027 to 2029 6,065 — 14,383 20,448 2030 to 2032 — — — — 2033 to 2035 — 197 — 197 Thereafter — — 322,729 322,729 $ 249,144 $ 197 $ 372,909 $ 622,250 (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 $241.8 million for federal. (2) In certain jurisdictions, the net operating loss carryforwards can only be used to offset a percentage of taxable income in a given year. (3) If certain substantial changes in the entity's ownership occur or have determined to have occurred, there may be a limitation on the amount of the carryforwards that can be utilized. As of December 31, 2019, the Company had tax credit carryforwards of $8.6 million , which expire, if not utilized, from 2020 to 2031. The beginning and ending balances of the Company's unrecognized tax benefits are reconciled below for the years ended December 31 (in thousands): 2019 2018 2017 Beginning balance $ 150,930 $ 82,390 $ 72,187 Gross increases related to prior year tax positions — 33,436 6,095 Gross decreases related to prior year tax positions (1,160 ) — — Gross increases related to current year tax positions 31,332 48,685 19,832 Decreases resulting from expiration of statute of limitation (2,112 ) (1,276 ) (15,410 ) Decreases resulting from settlements (5,264 ) (12,305 ) (314 ) Ending balance $ 173,726 $ 150,930 $ 82,390 The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense in the consolidated statements of operations. The Company accrued $14.2 million and $8.4 million for interest and penalties as of December 31, 2019 and 2018 , respectively. The unrecognized tax benefits of $173.7 million as of December 31, 2019 , if subsequently recognized, will affect the Company's effective tax rate favorably at the time when such a benefit is recognized, of which $30.8 million is subject to an indemnification agreement. Due to various tax years open for examination and the ongoing tax audits and inquiries by the tax authorities in different jurisdictions, 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, tax audit settlements, 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 the years from 2016 through current year remain open to examination by federal and state taxing authorities. In addition, the Company's tax years of 2007 through current year 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 Purchase Commitments Primarily as a result of the Company's various IBX expansion projects, as of December 31, 2019 , the Company was contractually committed for $0.8 billion 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, 2019 , such as commitments to purchase power in select locations through 2020 and thereafter, and other open purchase orders for goods, services or arrangements to be delivered or provided during 2020 and thereafter. Such other miscellaneous purchase commitments totaled $1.0 billion as of December 31, 2019 . In addition, the Company entered into lease agreements with various landlords primarily for data center spaces and ground lease which have not yet commenced as of December 31, 2019 . These leases will commence between fiscal years 2020 and 2022 , with lease terms of 10 to 49 years and a total lease commitment of approximately $608.1 million . Equity Contribution Commitments In connection with the Joint Venture closed in October 2019, the Company agreed to make future equity contributions to the Joint Venture of €17.6 million and £15.7 million , or $40.6 million in total at the exchange rate in effect on December 31, 2019 . 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. Although we believe that we have adequately assessed and accounted for our potential tax liabilities, and that our tax estimates are reasonable, there can be no certainty that additional taxes will not be due upon audit of our tax returns or as a result of further changes to the tax laws and interpretations thereof. For example, we are currently undergoing audits and appealing the tentative assessments in a number of jurisdictions where we operate, such as France and Brazil. The final results of these audits and outcome of the appeals are uncertain and may not be resolved in our favor. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations and appeals that would affect the adequacy of its tax accruals for each of the reporting periods. If any issues arising from the tax examinations and appeals 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 certain of its executive officers that provides for a severance payment equal to 100% of 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, or 200% of the executive officer's annual base salary and maximum bonus in the event this occurs after a change-in-control of the Company. For certain other executive officers, these benefits are only triggered after a change-in-control of the Company, in which case the officer is entitled to 200% of the executive officer's annual base salary and maximum bonus. In addition, under these agreements, 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 24 months. Indemnification and 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, 2019 . 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, 2019 . 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, 2019 . 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 does not have significant liabilities in connection with service level credits as of December 31, 2019 .

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): 2019 Quarters Ended March 31 June 30 September 30 December 31 Revenues $ 1,363,218 $ 1,384,977 $ 1,396,810 $ 1,417,135 Gross profit 681,188 686,798 692,471 691,499 Net income attributable to Equinix 118,078 143,527 120,850 124,995 Earnings per share attributable to Equinix: Basic 1.44 1.70 1.42 1.47 Diluted 1.44 1.69 1.41 1.46 2018 Quarters Ended March 31 June 30 September 30 December 31 Revenues $ 1,215,877 $ 1,261,943 $ 1,283,751 $ 1,310,083 Gross profit 593,447 610,142 623,442 639,148 Net income attributable to Equinix 62,894 67,618 124,825 110,022 Earnings per share attributable to Equinix: Basic 0.79 0.85 1.56 1.37 Diluted 0.79 0.85 1.55 1.36

Nature of Business and Summar_2

Nature of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
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: • Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands from April 18, 2019; • Metronode from the Ontario Teachers' Pension Plan Board (the "Metronode Acquisition") from April 18, 2018; • Infomart Dallas, including its operations and tenants, from ASB Real Estate Investments (the "Infomart Dallas Acquisition") from April 2, 2018; • Itconic, a data center business in Spain and Portugal from October 9, 2017; • Zenium's data center business in Istanbul from October 6, 2017; • certain colocation business from Verizon Communications Inc. ("Verizon") consisting of 29 data center buildings located in the United States ("U.S."), Brazil and Colombia (the "Verizon Data Center Acquisition") from May 1, 2017; • IO UK's data center operating business in Slough, United Kingdom ("IO Acquisition") from February 3, 2017.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with the accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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, and assets acquired and liabilities assumed from acquisitions, useful lives of intangible assets and property, plant and equipment, leases, asset retirement obligations, other accruals, 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 Investments	Cash, Cash Equivalents and Short-Term Investments The Company considers all highly liquid instruments with an original maturity from the date of purchase of 90 days or less to be cash equivalents. Cash equivalents consist of money market mutual funds and certificates of deposit with original maturities up to 90 days. Short-term investments generally consist of certificates of deposit with original maturities of between 90 days and 1 year. Publicly traded equity securities are measured at fair value with changes in the fair values recognized within other income (expense) in the Company's consolidated statements of operations. 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 Investments and Non-marketable Equity Investments	Equity Method Investments The Company enters into joint venture or partnership arrangements to invest in certain entities for business development objectives. At the inception of these arrangements, the Company assesses its interests with other entities to determine whether any of such entities meet the definition of a variable interest entity ("VIE"). A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support, or (ii) has equity investors who lack the characteristics of a controlling financial interest. The Company is required to consolidate the assets and liabilities of VIEs when it is deemed to be the primary beneficiary. The primary beneficiary of a VIE is the entity that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. As of December 31, 2019, the Company concluded that it did not have any significant investments in entities that are deemed to be VIEs. The Company’s investments in joint ventures and partnerships are generally accounted for under the equity method of accounting, as the Company concluded it does not have control, but has the ability to exercise significant influence over the investees. Equity method investments are initially measured at cost, or at fair value for a retained investment in the common stock of an investee in a deconsolidation transaction. Equity investments are subsequently adjusted for cash contributions, distributions and the Company's share of the income and losses of the investees. The Company records its equity method investments in other assets in the consolidated balance sheet. The Company's proportionate share of the income or loss from its equity method investments are recorded in other income in the consolidated statement of operations. The Company reviews its investments periodically to determine if any investments may be impaired considering both qualitative and quantitative factors that may have a significant impact on the investees' fair value. The Company did no t record any impairment charges related to its equity method investments for the years ended December 31, 2019, 2018 and 2017. Non-marketable Equity Investments The Company also has investments in non-marketable equity securities, where the Company does not have the ability to exercise significant influence over the investees. The Company elected the measurement alternative under which the securities are measured at cost minus impairment, if any, and adjusted for changes resulting from qualifying observable price changes. The Company records non-marketable equity investment in other assets in the consolidated balance sheet. The Company reviews its non-marketable equity investments quarterly to determine if any investments may be impaired considering both qualitative and quantitative factors that may have a significant impact on the investees' fair value. The Company did no t record any impairment charges related to its non-marketable equity investments for the years ended December 31, 2019, 2018 and 2017.
Financial Instruments and Concentration of Credit Risk	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-bottom:16px;padding-top:16px;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Financial Instruments and Concentration of Credit Risk</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:16px;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">Financial instruments which potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. Risks associated with cash and cash equivalents and short-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 or A-/A3 Long Term Rating, as determined by independent credit rating agencies.</font></div><div style="line-height:120%;padding-bottom:4px;padding-top:12px;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">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. </font></div></div>
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at the Company's original cost or at fair value for property, plant and equipment acquired through acquisitions, net of depreciation. 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 through acquisition are amortized over the shorter of the useful life of the assets or terms that include 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 3-40 years Buildings 12-58 years Leasehold improvements 12-40 years 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.
Assets Held for Sale	Assets Held for Sale Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale are reported at the lower of their carrying amounts or fair values less costs to sell. The Company recorded an impairment charge of $15.8 million
Asset Retirement Costs and Asset Retirement Obligations	Asset Retirement Costs and Asset Retirement Obligations
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. Goodwill is not amortized and is tested for impairment at least annually or more often if and when circumstances indicate that goodwill is not recoverable. The Company assesses 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. Qualitative factors considered in the assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting the reporting unit. 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 a quantitative impairment test is unnecessary. However, if the Company concludes otherwise, then it is required to perform a quantitative goodwill impairment test. The quantitative impairment test, which is used to identify both the existence of impairment and the amount of impairment loss, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying value of the reporting unit exceeds its fair value, any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. As of December 31, 2019, 2018 and 2017, 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.
Debt Issuance Costs	Debt Issuance Costs Costs and fees incurred upon debt issuances are capitalized and are amortized over the life of the related debt 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 obligation and debt issuance costs related to the revolving credit facility are presented as other assets.
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company uses derivative instruments, including foreign currency forwards and options and cross-currency interest rate swaps, to manage certain foreign currency exposures. Derivative instruments are viewed as risk management tools by the Company and are not used for speculative purposes. The Company recognizes all derivatives on the Company's consolidated balance sheets at fair value. The accounting for changes in the value of a derivative depends on whether the contract qualifies and has been designated 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 and 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 the effectiveness assessment methodology. For cash flow hedges, the Company uses regression analysis at the time they are designated to assess their effectiveness. Hedge designations are reviewed on a quarterly basis to assess whether circumstances have changed that would disrupt the hedge instrument's relationship to the forecasted transactions or net investment. The Company uses the forward method to assess effectiveness of qualifying foreign currency forwards that are designated as cash flow hedges, whereby, the change in the fair value of the derivative is recorded in other comprehensive income (loss) and reclassified to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item when the hedged item affects earnings. The Company uses the spot method to assess effectiveness of qualifying foreign currency exchange options that are designated as cash flow hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and reclassified to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item when the hedged item affects earnings, and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized on a straight-line basis to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item. When two or more derivative instruments in combination are jointly designated as a cash flow hedging instrument, as with foreign currency exchange option collars, they are treated as a single instrument. If the hedge relationship is terminated for any derivatives designated as cash flow hedges, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the previously hedged item affects earnings, consistent with the original hedge strategy. For hedge relationships that are discontinued because the forecasted transaction is not expected to occur according to the original strategy, then any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings. From time to time, the Company enters into treasury lock agreements to add stability to interest expense and to manage its exposure to interest rate movements. A treasury lock is a synthetic forward sale of a U.S. treasury note which is settled in cash based upon the difference between an agreed upon treasury rate and the prevailing treasury rate at settlement. It is entered into to effectively fix the treasury rate component of an upcoming debt issuance. The treasury lock transactions are designated as cash flow hedges, with all changes in value reported in other comprehensive income (loss). Subsequent to settlement, amounts in other comprehensive income are reclassified to interest expense as interest payments are accrued on the debt. The Company uses the spot method to assess effectiveness of cross-currency interest rate swaps that are designated as net investment hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized to interest expense on a straight-line basis. From time to time, the Company also uses 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. The Company uses the spot method to assess effectiveness of qualifying foreign currency forwards that are designated as net investment hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized to interest expense on a straight-line basis. Foreign currency gains or losses associated with derivatives that are not designated as hedging instruments for accounting purposes are recorded within other income (expense) in the Company's condensed consolidated statements of operations, with the exception of (i) foreign currency embedded derivatives contained in certain of the Company's customer contracts and (ii) foreign exchange forward contracts that are entered into to hedge the accounting impact of the foreign currency embedded derivatives, which are recorded within revenues in the Company's condensed consolidated statements of operations. Derivative Assets and Liabilities
Fair Value of Financial Instruments and Fair Value Measurements	Fair Value of Financial Instruments The carrying value of the Company's cash and cash equivalents, short-term investments and derivative instruments 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, certificates of deposit, 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; and • Asset retirement obligations initially measured at fair value but not subsequently measured at fair value.
Leases	Leases The Company determines if an arrangement is or contains a lease at its inception. The Company enters into lease arrangements primarily for data center spaces, office spaces and equipment. The Company recognizes a right-of-use ("ROU") asset and lease liability on the consolidated balance sheet for all leases with a term longer than 12 months, including renewals. ROU assets represent the Company's right to use an underlying asset for the lease term. Lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and liabilities are classified and recognized at the commencement date. ROU liabilities are measured based on the present value of fixed lease payments over the lease term. ROU assets consist of (i) initial measurement of the lease liability; (ii) lease payments made to the lessor at or before the commencement date less any lease incentives received; and (iii) initial direct costs incurred by the Company. Lease payments may vary because of changes in facts or circumstances occurring after the commencement, including changes in inflation indices. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate) are included in the measurement of ROU assets and lease liabilities using the index or rate at the commencement date. Variable lease payments that do not depend on an index or a rate are excluded from the measurement of ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. Since most of the Company's leases do not provide an implicit rate, the Company uses its own incremental borrowing rate ("IBR") on a collateralized basis in determining the present value of lease payments. The Company utilizes a market-based approach to estimate the IBR. The approach requires significant judgment. Therefore, the Company utilizes different data sets to estimate IBRs via an analysis of (i) yields on comparable credit rating composite curves; (ii) sovereign rates; (iii) yields on our outstanding public debt; and (iv) historical difference in yields on the curves of our secured and unsecured rated debt. The Company also applies adjustments to account for considerations related to (i) tenor; and (ii) country credit rating that may not be fully incorporated by the aforementioned data sets. The majority of the Company's lease arrangements include options to extend the lease. If the Company is reasonably certain to exercise such options, the periods covered by the options are included in the lease term. The depreciable lives of certain fixed assets and leasehold improvements are limited by the expected lease term. The Company has certain leases with an initial term of 12 months or less. For such leases, the Company elected not to recognize any ROU asset or lease liability on the consolidated balance sheet. The Company has lease agreements with lease and non-lease components. The Company elected to account for the lease and non-lease components as a single lease component for all classes of underlying assets for which the Company has identified lease arrangements.
Revenue	Revenue 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 solutions 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 by service lines and geographic areas are included in segment information (see Note 17). Under the revenue accounting guidance, revenues are recognized when control of these products and services is transferred to its customers, in an amount that reflects the consideration it expects to be entitled to in exchange for the products and services. Revenues from recurring revenue streams are generally billed monthly and recognized ratably over the term of the contract, generally 1 to 3 years for IBX data center colocation customers. Non-recurring installation fees, although generally paid upfront upon installation, are deferred and recognized ratably over the contract term. Professional service fees and equipment sales are recognized in the period when the services were provided. For the contracts with customers that contain multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct or as a series of distinct obligations if the individual performance obligations meet the series criteria. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The transaction price is allocated to the separate performance obligation on a relative standalone selling price basis. The standalone selling price is determined based on overall pricing objectives, taking into consideration market conditions, geographic locations and other factors. Other judgments include determining if any variable consideration should be included in the total contract value of the arrangement such as price increases. Revenue is generally recognized on a gross basis as a principal versus on a net basis as an agent, as the Company is primarily responsible for fulfilling the contract, bears inventory risk and has discretion in establishing the price when selling to the customer. To the extent the Company does not meet the criteria for recognizing revenue on a gross basis, the Company records the revenue on a net basis. Revenue from contract settlements, when a customer wishes to terminate their contract early, is treated as a contract modification and recognized ratably over the remaining term of the contract, if any. The Company guarantees certain service levels, such as uptime, as outlined in individual customer contracts. If these service levels are not achieved due to any failure of the physical infrastructure or offerings, or in the event of certain instances of damage to customer infrastructure within the Company's IBX data centers, the Company would reduce revenue for any credits or cash payments given to the customer. Historically, these credits and cash payments have not been significant. The Company enters into revenue contracts with customers for data centers and office spaces, which contain both lease and non-lease components. The Company elected to adopt the practical expedient which allows lessors to combine lease and non-lease components, by underlying class of asset, and account for them as one component if they have the same timing and pattern of transfer. The combined component is accounted for in accordance with the current lease accounting guidance ("Topic 842") if the lease component is predominant, and in accordance with the current revenue accounting guidance ("Topic 606") if the non-lease component is predominant. Lessors are permitted to adopt this practical expedient on a retrospective or prospective basis. The Company elected to apply the practical expedient prospectively based on classes of underlying assets. In general, customer contracts for data centers are accounted for under Topic 606 and Customer contracts for the use of office space are accounted for under Topic 842, which are generally classified as operating leases and are recognized on a straight-line basis over the lease term. Certain customer agreements are denominated in currencies other than 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 assessed these embedded contracts and concluded them to be foreign currency embedded derivatives (see Note 8). 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. Contract Balances The timing of revenue recognition, billings and cash collections result in accounts receivables, contract assets and deferred revenues. A receivable is recorded at the invoice amount, net of an allowance for doubtful account and is recognized in the period when the Company has transferred products or provided services to its customers and when its right to consideration is unconditional. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 45 days. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that the Company's contracts generally do not include a significant financing component. 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. 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 uncollectable are charged to bad debt expense included in sales and marketing 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. A contract asset exists when the Company has transferred products or provided services to its customers, but customer payment is contingent upon satisfaction of additional performance obligations. Certain contracts include terms related to price arrangements such as price increases and free months. The Company recognizes revenues ratably over the contract term, which could potentially give rise to contract assets during certain periods of the contract term. Contract assets are recorded in other current assets and other assets in the consolidated balance sheet. Deferred revenue (a contract liability) is recognized when the Company has an unconditional right to a payment before it transfers products or services to customers. Deferred revenue is included in other current liabilities and other liabilities, respectively, in the consolidated balance sheet. Contract Costs Direct and indirect incremental costs solely related to obtaining revenue contracts are capitalized as costs of obtaining a contract, when they are incremental and if they are expected to be recovered. Such costs consist primarily of commission fees and sales bonuses, as well as indirect related payroll costs. Contract costs are amortized over the estimated period of benefit on a straight-line basis. The Company elected to apply the practical expedient which allows the Company to expense contract costs when incurred, if the amortization period is one year or less.
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 and operating loss and tax credits carryforwards. 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. Recognized income tax positions are measured at the largest amount that has a greater than 50 percent likelihood of being realized. Any subsequent changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company elected to be taxed as a REIT for U.S. federal income tax purposes beginning with its 2015 taxable year. 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 U.S. federal taxable income of the Company and its QRSs, resulting in no U.S. income tax due. However, the Company's taxable REIT subsidiaries ("TRSs") will continue to be subject to the U.S. corporate 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 QRSs or TRSs. The Company's qualification and taxation as a REIT depends on its satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. The Company's ability to satisfy quarterly asset tests depends upon its analysis and the fair market values of its REIT and non-REIT assets. For purposes of the quarterly REIT asset tests, the Company estimates the fair market value of assets within its QRSs and TRSs using a discounted cash flow approach, by calculating the present value of forecasted future cash flows. The Company applies discount rates based on industry benchmarks relative to the market and forecasting risks. Other significant assumptions used to estimate the fair market value of assets in QRSs and TRSs include projected revenue growth, projected operating margins, and projected capital expenditures. The Company revisits significant assumptions periodically to reflect any changes due to business or economic environment.
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. The Company generally recognizes stock-based compensation expense on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. 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. The Company elected to estimate forfeitures based on historical forfeiture rates. 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 4 years, although certain of the equity awards for executives vest over a range of 2 to 4 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 was based on average dividend yields and 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 records the excess tax benefits from stock-based compensation as income tax expense through the statement of operations.
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 in the period incurred and recorded within other income (expense). Certain inter-company balances are designated as loans of a long-term investment-type nature. 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
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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In December 2019, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes ("Topic 740"): Simplifying the Accounting for Income T axes. The ASU simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public entities, the ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued. The Company is currently evaluating the extent of the impact that the adoption of this standard will have on its condensed 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 qualitative and quantitative 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. 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 will adopt this new ASU on January 1, 2020. The Company is assessing the impact of this ASU on its accounting for allowances for doubtful accounts, but does not expect the adoption of this standard to have a significant impact on its condensed consolidated financial statements. Accounting Standards Recently Adopted Revenue In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09") and issued subsequent amendments to the initial guidance, collectively referred as "Topic 606." On January 1, 2018, the Company adopted Topic 606 using the modified retrospective approach applied to those contracts, which were not completed as of January 1, 2018, and recognized a net increase to the opening retained earnings of $269.8 million , net of tax impacts. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while the comparative information has not been restated and continues to be reported under accounting standards in effect for those periods. Derivatives and Hedging In August 2017, FASB issued ASU 2017-12 Derivatives and Hedging ("Topic 815"): Targeted Improvements to Accounting for Hedging Activities. This ASU was issued to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and to simplify the application of the hedge accounting guidance in current GAAP. This ASU permits hedge accounting for risk components involving nonfinancial risk and interest rate risk, requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the hedged item is reported, no longer requires separate measurement and reporting of hedge ineffectiveness, eases the requirement for hedge effectiveness assessment, and requires a tabular disclosure related to the effect on the income statement of fair value and cash flow hedges. This ASU is effective for annual or any interim reporting periods beginning after December 15, 2018 with early adoption permitted. The Company adopted ASU 2017-12 on January 1, 2019 using the modified retrospective approach. For cash flow hedges existing on the date of adoption, the Company recognized the cumulative effect of the change on the opening balance of accumulated other comprehensive income (loss) with a corresponding adjustment to the opening balance of retained earnings for amounts previously recognized in earnings related to ineffectiveness. The adoption of this standard did not have a material impact on the Company's condensed consolidated financial statements. Leases In February 2016, FASB issued ASU 2016-02, Leases and issued subsequent amendments to the initial guidance, collectively referred to as "Topic 842." Topic 842 replaces the guidance in former ASC Topic 840, Leases. The new lease guidance increases transparency and comparability among organizations by requiring the recognition of the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's future obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use ("ROU") 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. Topic 842 allows entities to adopt with one of two methods: the modified retrospective transition method or the alternative transition method. On January 1, 2019, the Company adopted Topic 842 using the alternative transition method. Therefore, results for reporting periods beginning after January 1, 2019 are presented under Topic 842, while comparative information has not been restated and continues to be reported under accounting standards in effect for those periods. The Company recognized the cumulative effects of initially applying the standard as an adjustment to the opening balance of retained earnings in the period of adoption. In adopting the new guidance, the Company elected to apply the package of practical expedients permitted under the transition guidance which allows the Company not to reassess (1) whether any expired or existing contracts contain leases under the new definition of a lease; (2) lease classification for any expired or existing leases; and (3) whether previously capitalized initial direct costs would qualify for capitalization under Topic 842. The Company also elected to apply the land easements practical expedient which permits the Company not to assess at transition whether any expired or existing land easements are, or contain, leases if they were not previously accounted for as leases under Topic 840. Adoption of the standard had a significant impact on the Company's financial results, including the (1) recognition of new ROU assets and liabilities on its balance sheet for all operating leases; and (2) de-recognition of existing build-to-suit assets and liabilities with cumulative effects of initially applying the standard as an adjustment to the retained earnings. The cumulative effect of the changes made to its consolidated January 1, 2019 balance sheet from the adoption of Topic 842 was as follows (in thousands): Balance Sheet Balances at December 31, 2018 Adjustments due to adoption of Topic 842 Balances at January 1, 2019 Assets Other current assets $ 274,857 $ (15,949 ) $ 258,908 Property, plant and equipment, net 11,026,020 (293,111 ) 10,732,909 Operating lease right-of-use assets — 1,468,762 1,468,762 Intangible assets, net 2,333,296 (23,205 ) 2,310,091 Other assets 533,252 (63,468 ) 469,784 Liabilities Current portion of operating lease liabilities — 144,405 144,405 Current portion of finance lease liabilities — 70,795 70,795 Current portion of capital lease and other financing obligations 77,844 (77,844 ) — Other current liabilities 126,995 (6,455 ) 120,540 Operating lease liabilities, less current portion — 1,312,262 1,312,262 Finance lease liabilities, less current portion — 1,165,188 1,165,188 Capital lease and other financing obligations, less current portion 1,441,077 (1,441,077 ) — Other liabilities 629,763 (88,272 ) 541,491 Equity Retained Earnings 889,948 (5,973 ) 883,975
Fair Value 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.
