Equinix, Inc. ("Equinix" or the "Company") was incorporated in Delaware on June 22, 1998. Equinix provides colocation space and related offerings. Global enterprises, content providers, financial companies and network service providers rely upon Equinix's insight and expertise to safehouse and connect their most valued information assets. The Company operates International Business Exchange^TM ("IBX^®") data centers, or IBX data centers, across the Americas; Europe, Middle East and Africa ("EMEA") and Asia-Pacific geographic regions where customers directly interconnect with a network ecosystem of partners and customers. More than 1,800 network service providers offer access to the world's internet routes inside the Company's IBX data centers. This access to internet routes provides Equinix customers improved reliability and streamlined connectivity while significantly reducing costs by reaching a critical mass of networks within a centralized physical location. As of December 31, 2019, the Company operated 204 IBX data centers in 53 markets across five continents.

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.

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.

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.

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 not record any impairment charges related to its equity method investments for the years ended December 31, 2019, 2018 and 2017.

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 not record any impairment charges related to its non-marketable equity investments for the years ended December 31, 2019, 2018 and 2017.

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.

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 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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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 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.

In December 2019, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes ("Topic 740"): Simplifying the Accounting for Income Taxes. 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.

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.

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.

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):
