Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. (“Equinix” or the “Company”) and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2014 has been derived from audited consolidated financial statements as of that date. The consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission (“SEC”), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”). For further information, refer to the Consolidated Financial Statements and Notes thereto included in Equinix’s Form 10-K as filed with the SEC on March 2, 2015. Results for the interim periods are not necessarily indicative of results for the entire fiscal year. Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Equinix and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Income Taxes In September 2012, the Company announced that its Board of Directors approved a plan for Equinix to pursue conversion to a real estate investment trust (“REIT”). On December 23, 2014, its Board of Directors formally approved its conversion to a REIT effective on January 1, 2015. The Company completed the implementation of the REIT conversion in 2014, and as a result the Company has elected to be treated as a REIT for federal income tax purposes effective January 1, 2015. In May 2015, the Company received a favorable response to the private letter ruling (“PLR”) it had requested from the U.S. Internal Revenue Service (“IRS”) in connection with the Company’s conversion to a REIT for federal income tax purposes. As a result, the Company may deduct the distributions made to its shareholders from taxable income generated by the Company and its Qualified REIT Subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the taxable income of the Company and its QRSs, resulting in no U.S. income tax due. However, the Taxable REIT Subsidiaries (“TRSs”) will continue to be subject to income taxes on any taxable income generated by them. In addition, the foreign operations of the Company will continue to be subject to local income taxes regardless of whether the foreign operations are operated as a QRS or a TRS. The Company provides for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate is subject to change in the future due to various factors such as the operating performances of the REIT and TRSs, tax law changes and future business acquisitions. The Company’s effective tax rates were 9.2% and 18.3% for the six months ended June 30, 2015 and 2014, respectively. The decrease in the effective tax rate is primarily due to the reduced tax rate as a result of the REIT conversion. As a REIT, the Company is entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. Recent Accounting Pronouncements In May 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-07, Fair Value Measurement, which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using the net asset value per share of the investment. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. A reporting entity should apply the amendment retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. The Company does not believe the adoption of ASU 2015-07 will have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (“ASU 2015-03”), to simplify the presentation of debt issuance costs. The ASU requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs is not affected by this ASU. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidations (“ASU 2015-02”). This ASU requires companies to adopt a new consolidation model, specifically: (1) the ASU modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (2) the ASU eliminates the presumption that a general partner should consolidate limited partnership; (3) the ASU affects the consolidation analysis of reporting entities that involved with VIEs and (4) the ASU provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In January 2015, FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items (“ASU 2015-01”), to simplify the income statement presentation requirements by eliminating the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not believe the adoption of ASU 2015-01 will have a significant impact on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016, with early adoption permitted. The Company does not believe the adoption of ASU 2014-15 will have a significant impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This ASU requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which companies expect to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. This ASU is effective for fiscal years and interim periods beginning after December 15, 2016. On July 9, 2015, the FASB decided to delay the effective date of this standard to annual reporting periods beginning after December 15, 2017. The FASB permitted early adoption of this standard, but with an adoption date no earlier than December 15, 2016, the original effective date of this ASU. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	3. Acquisitions Nimbo Acquisition On January 14, 2015, the Company acquired all of the issued and outstanding share capital of Nimbo Technologies Inc. (“Nimbo”), a company which specializes in migrating business applications to the cloud with extensive experience moving legacy applications into a hybrid cloud architecture, and connecting legacy data centers to the cloud, for a cash payment of $10,000,000 and a contingent earn-out arrangement to be paid over two years (the “Nimbo Acquisition”). Nimbo continues to operate under the Nimbo name. The Nimbo Acquisition was accounted for using the acquisition method. As a result of the Nimbo Acquisition, the Company recorded goodwill of $17,154,000, which represents the excess of the total purchase price over the fair value of the assets acquired and liabilities assumed. The Company recorded the contingent earn-out arrangement at its estimated fair value. The results of operations for Nimbo are not significant to the Company; therefore, the Company does not present its purchase price allocation or pro forma combined results of operations. In addition, any prospective changes in the Company’s earn-out estimates are not expected to have a material effect on the Company’s consolidated statement of operations. Offer for TelecityGroup On May 29, 2015, the Company announced a cash and share offer for the entire issued and to be issued share capital of Telecity Group plc (“TelecityGroup”) for total consideration of approximately £2,351,900,000 or $3,594,409,000. The Company expects to close this transaction in the first half of 2016. As the offer to TelecityGroup includes an element of cash, the Company is required to include a confirmation that the Company has sufficient cash available to fulfill the offer, according to the UK Takeover Code. As a result, the Company placed £322,851,000 or approximately $493,801,000 into a restricted cash account, which was included in the current portion of restricted cash in its condensed consolidated balance sheet. In addition, the Company entered into a bridge credit agreement with J.P. Morgan Chase Bank, N.A. (“JPMCB”) as the initial lender and as administrative agent for the lenders from time to time party thereto (the “Lenders”) for a principal amount of £875,000,000 or approximately $1,340,000,000 (the “Bridge Loan”). The Bridge Loan has an initial maturity of 12 months from the date of the first drawdown and, at the initial maturity date (if not repaid prior to that time), will be converted into seven-year extended bridge loans. The total estimated initial commitment fees associated with the Bridge Loan are approximately £4,375,000 or $6,701,000 and will be paid on the earlier of the consummation of the acquisition and the termination of the Bridge Loan. As of June 30, 2015, the Company had accrued commitment fees of approximately $1,337,000 associated with the Bridge Loan in interest expense in its condensed consolidated statement of operations. The Bridge Loan bears interest during the first three months in which the funds are advanced, at an initial annual rate of LIBOR plus 5.00%. Thereafter, the rate for each subsequent three-month period increases by 0.5% over the applicable margin in effect for the immediately preceding three-month period, subject to a cap (the “Total Cap”). Prior to February 28, 2016, the Total Cap is equal to 1.50% plus the greatest of (i) the yield on the Company’s 5.750% senior notes due 2025, (ii) the yield on the J.P. Morgan US Dollar Global High Yield Index minus 1.21% and (iii) 4.875%. On and after February 28, 2016, the Total Cap is equal to 1.75% plus the greatest of (i) the yield on the Company’s 5.750% senior notes due 2025, (ii) the yield on the J.P. Morgan US Dollar Global High Yield Index minus 1.21% and (iii) 4.875%. Under certain circumstances the Bridge Loan will bear interest at the Total Cap as determined weekly. The Bridge Loan is unsecured and is guaranteed by certain of the Company’s domestic subsidiaries. As of June 30, 2015, the Company had not made any advances on the Bridge Loan. The Company intends to obtain permanent financing prior to the closing of the TelecityGroup acquisition to replace and terminate the Bridge Loan.

Leases [Abstract]
Leases	6. Leases Capital Lease and Other Financing Obligations Atlanta 1 Capital Lease In May 2015, the Company entered into a lease amendment to extend the lease term of the Company’s Atlanta 1 IBX (the “AT1 Lease”). The lease was originally accounted for as an operating lease. Pursuant to the accounting standard for leases, the Company reassessed the lease classification of the AT1 Lease as a result of the lease amendment and determined that upon the amendment the lease should be accounted for as a capital lease. The Company recorded a capital lease asset and liability totaling approximately $21,274,000 during the three months ended June 30, 2015. The lease term was extended to September 2035. Atlanta 2 Capital Lease In January 2015, the Company entered into a lease amendment to extend the lease term of the Company’s Atlanta 2 IBX (the “AT2 Lease”). The lease was originally accounted for as an operating lease. Pursuant to the accounting standard for leases, the Company reassessed the lease classification of the AT2 Lease as a result of the lease amendment and determined that upon the amendment the lease should be accounted for as a capital lease. The Company recorded a capital lease asset totaling approximately $25,960,000 and a capital lease liability totaling approximately $26,230,000 during the three months ended March 31, 2015.

The Original Credit Agreement provided for a senior credit facility of $1,500,000,000, comprised of (i) a $1,000,000,000 senior secured multi-currency revolving credit facility and (ii) a $500,000,000 senior secured term loan facility (the “Term Loan Facility”). The Amended Credit Agreement facilitated the conversion of the outstanding U.S. dollar-denominated principal amount of the Term Loan Facility to an approximately equivalent amount denominated in four foreign currencies. In connection with the execution of the Amended Credit Agreement, on April 30, 2015 the Company prepaid the U.S. dollar-denominated $490,000,000 principal balance of the Term Loan Facility and immediately re-borrowed under the Term Loan Facility the aggregate principal amounts of CHF 47,780,000, €184,945,000, £92,586,000 and ¥11,924,000,000, or approximately $490,000,000. The Company accounted for this transaction as a debt modification. The Company did not incur any gains or losses relating to the debt modification. The Company will repay the Term Loan Facility in equal quarterly installments on the last business day of each March, June, September and December, commencing on June 30, 2015, equal to the amount of 2.00% of the result of the respective Term Loan Facility on April 30, 2015 divided by 0.98. The remaining principal amount will be paid on the maturity date of the Term Loan Facility. Convertible Debt The Company’s convertible debt consisted of the following (in thousands): June 30, December 31, 4.75% convertible subordinated notes $ 157,885 $ 157,885 Less amount representing debt discount (8,105 ) (12,032 ) $ 149,780 $ 145,853 4.75% Convertible Subordinated Notes Holders of the 4.75% convertible subordinated notes were eligible to convert their notes during the quarter ended June 30, 2015 and are eligible to convert their notes during the three months ending September 30, 2015, since the stock price condition conversion clause was met during the applicable periods. As of June 30, 2015, had the holders of the 4.75% convertible subordinated notes converted their notes, the 4.75% convertible subordinated notes would have been convertible into a maximum of 1,964,879 shares of the Company’s common stock. The 4.75% convertible subordinated notes are scheduled to mature on June 15, 2016. Upon maturity (and assuming that no conversion occurs prior to such maturity), the Company will be obligated to settle any outstanding principal amount of the notes and accrued interest in cash. In addition, should conversion occur prior to maturity, the Company may, at its election, settle the obligation either in cash, stock or a combination of cash and stock. To minimize the impact of potential dilution upon conversion of the 4.75% convertible subordinated notes, the Company entered into capped call transactions (the “Capped Call”) separate from the issuance of the 4.75% convertible subordinated notes and paid a premium of $49,664,000 for the Capped Call in 2009. The Capped Call covers a total of approximately 4,432,638 shares of the Company’s common stock, subject to adjustment. Under the Capped Call, the Company effectively raised the conversion price of the 4.75% convertible subordinated notes from $84.32 to $114.82. Pursuant to the declaration of the quarterly dividend in May 2015, the Company further amended the Capped Call agreement to adjust the effective conversion price of the 4.75% convertible subordinated notes from $80.36 to $109.34 per share of common stock. Depending upon the Company’s stock price at the time the 4.75% convertible subordinated notes are redeemed, the settlement of the Capped Call will result in a delivery of up to 1,232,808 shares of the Company’s common stock to the Company; however, the Company will receive no benefit from the Capped Call if the Company’s stock price is $80.36 or lower at the time of conversion and will receive less shares than the 1,232,808 share maximum as described above for share prices in excess of $109.34 at the time of conversion than it would have received at a share price of $109.34 (the Company’s benefit from the Capped Call is capped at $109.34 and the benefit received begins to decrease above this price). Senior Notes The Company’s senior notes consisted of the following as of (in thousands): June 30, December 31, 5.375% Senior Notes due 2023 $ 1,000,000 $ 1,000,000 5.375% Senior Notes due 2022 750,000 750,000 4.875% Senior Notes due 2020 500,000 500,000 5.75% Senior Notes due 2025 500,000 500,000 $ 2,750,000 $ 2,750,000 Maturities of Debt Facilities The following table sets forth maturities of the Company’s debt, including mortgage and loans payable, convertible debt and senior notes and excluding debt discounts and premium as of June 30, 2015 (in thousands): Year ending: 2015 (6 months remaining) $ 29,516 2016 216,958 2017 52,885 2018 48,330 2019 348,585 Thereafter 2,778,674 $ 3,474,948 Fair Value of Debt Facilities The following table sets forth the estimated fair values of the Company’s mortgage and loans payable, senior notes and convertible debt, including current maturities, as of (in thousands): June 30, December 31, Mortgage and loans payable $ 549,090 $ 553,045 Convertible debt 159,514 162,159 Senior notes 2,748,513 2,790,023 The Company has determined that the inputs used to value its debt facilities fall within Level 2 of the fair value hierarchy.

Commitments and Contingencies	8. Commitments and Contingencies Purchase Commitments Primarily as a result of the Company’s various IBX expansion projects, as of June 30, 2015 the Company was contractually committed for $259,984,000 of unaccrued capital expenditures, primarily for IBX equipment not yet delivered and labor not yet provided, in connection with the work necessary to open these IBX data centers and make them available to customers for installation. In addition, the Company had numerous other, non-capital purchase commitments in place as of June 30, 2015, such as commitments to purchase power in select locations through the remainder of 2015 and thereafter, and other open purchase orders for goods or services to be delivered or provided during the remainder of 2015 and thereafter. Such other miscellaneous purchase commitments totaled $367,368,000 as of June 30, 2015. In connection with the cash and share offer to TelecityGroup, the Company has entered into a cooperation agreement with TelecityGroup to secure the clearances and authorization necessary to satisfy the regulatory pre-condition to the TelecityGroup acquisition. The Company has agreed to pay to TelecityGroup £50,000,000 or approximately $76,415,000 if: (i) on or prior to November 29, 2016, the Company invokes the regulatory approvals condition, or (ii) on November 29, 2016, the regulatory approvals condition is not satisfied or waived by the Company.

Stockholders’ Equity Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss, net of tax, are as follows (in thousands): Balance as of Net Balance as of Foreign currency translation adjustment (“CTA”) gain (loss) $ (336,946 ) $ (76,869 ) $ (413,815 ) Unrealized gain (loss) on cash flow hedges 6,603 (3,734 ) 2,869 Unrealized gain (loss) on available for sale securities (99 ) 120 21 Net investment hedge CTA loss — (10,389 ) (10,389 ) Defined benefit plans (2,001 ) 142 (1,859 ) $ (332,443 ) $ (90,730 ) $ (423,173 ) Changes in foreign currency exchange rates can have a significant impact to the Company’s consolidated balance sheets (as evidenced above in the Company’s foreign currency translation gain or loss), as well as its consolidated results of operations, as amounts in foreign currencies are generally translating into more U.S. dollars when the U.S. dollar weakens or less U.S. dollars when the U.S. dollar strengthens. As of June 30, 2015, the U.S. dollar was generally stronger relative to certain of the currencies of the foreign countries in which the Company operates. The strength of the U.S. dollar had an overall negative impact on the Company’s consolidated financial position because the foreign denominations translated into fewer U.S. dollars as evidenced by the increase in foreign currency translation loss for the six months ended June 30, 2015 as reflected in the above table. In future periods, the volatility of the U.S. dollar as compared to the other currencies in which the Company operates could have a significant impact on its consolidated financial position and results of operations including the amount of revenue that the Company reports in future periods. Dividends On May 7, 2015, the Company declared a quarterly cash dividend of $1.69 per share, with a record date of May 27, 2015 and a payment date of June 17, 2015. The Company paid a total of $96,203,000 on June 17, 2015 for the second quarter cash dividend. In addition, the Company accrued an additional $2,443,000 in dividends payable for the restricted stock units that have not yet vested. On February 19, 2015, the Company declared a quarterly cash dividend of $1.69 per share, with a record date of March 11, 2015 and a payment date of March 25, 2015. The Company paid a total of $96,196,000 on March 25, 2015 for the first quarter cash dividend. In addition, the Company accrued an additional $2,630,000 in dividends payable for the restricted stock units that have not yet vested. Stock-Based Compensation In February 2015, the Compensation Committee and the Stock Award Committee of the Company’s Board of Directors approved the issuance of an aggregate of 586,646 shares of restricted stock units to certain employees, including executive officers, pursuant to the 2000 Equity Incentive Plan, as part of the Company’s annual refresh program. These equity awards are subject to vesting provisions and have a weighted-average grant date fair value of $222.40 and a weighted-average requisite service period of 3.44 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. In connection with the Company’s REIT conversion, the Company used revenue and adjusted funds from operations (“AFFO”) as the performance measurements in the restricted stock units with both service and performance conditions that were granted in February 2015, whereby revenue and adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”) were used as the performance measurements in prior years’ grants. The Company uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition. There were no significant changes in the assumptions used to determine the fair value of restricted stock units with a service and market condition that were granted during the three months ended March 31, 2015 compared to the three months ended March 31, 2014.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. (“Equinix” or the “Company”) and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2014 has been derived from audited consolidated financial statements as of that date. The consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission (“SEC”), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”). For further information, refer to the Consolidated Financial Statements and Notes thereto included in Equinix’s Form 10-K as filed with the SEC on March 2, 2015. Results for the interim periods are not necessarily indicative of results for the entire fiscal year.
Consolidation	Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Equinix and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Income Taxes	Income Taxes In September 2012, the Company announced that its Board of Directors approved a plan for Equinix to pursue conversion to a real estate investment trust (“REIT”). On December 23, 2014, its Board of Directors formally approved its conversion to a REIT effective on January 1, 2015. The Company completed the implementation of the REIT conversion in 2014, and as a result the Company has elected to be treated as a REIT for federal income tax purposes effective January 1, 2015. In May 2015, the Company received a favorable response to the private letter ruling (“PLR”) it had requested from the U.S. Internal Revenue Service (“IRS”) in connection with the Company’s conversion to a REIT for federal income tax purposes. As a result, the Company may deduct the distributions made to its shareholders from taxable income generated by the Company and its Qualified REIT Subsidiaries (“QRSs”). The Company’s dividends paid deduction generally eliminates the taxable income of the Company and its QRSs, resulting in no U.S. income tax due. However, the Taxable REIT Subsidiaries (“TRSs”) will continue to be subject to income taxes on any taxable income generated by them. In addition, the foreign operations of the Company will continue to be subject to local income taxes regardless of whether the foreign operations are operated as a QRS or a TRS. The Company provides for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate is subject to change in the future due to various factors such as the operating performances of the REIT and TRSs, tax law changes and future business acquisitions. The Company’s effective tax rates were 9.2% and 18.3% for the six months ended June 30, 2015 and 2014, respectively. The decrease in the effective tax rate is primarily due to the reduced tax rate as a result of the REIT conversion. As a REIT, the Company is entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-07, Fair Value Measurement, which permits a reporting entity, as a practical expedient, to measure the fair value of certain investments using the net asset value per share of the investment. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. A reporting entity should apply the amendment retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. The Company does not believe the adoption of ASU 2015-07 will have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (“ASU 2015-03”), to simplify the presentation of debt issuance costs. The ASU requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs is not affected by this ASU. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidations (“ASU 2015-02”). This ASU requires companies to adopt a new consolidation model, specifically: (1) the ASU modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (2) the ASU eliminates the presumption that a general partner should consolidate limited partnership; (3) the ASU affects the consolidation analysis of reporting entities that involved with VIEs and (4) the ASU provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements. In January 2015, FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items (“ASU 2015-01”), to simplify the income statement presentation requirements by eliminating the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not believe the adoption of ASU 2015-01 will have a significant impact on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016, with early adoption permitted. The Company does not believe the adoption of ASU 2014-15 will have a significant impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This ASU requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which companies expect to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. This ASU is effective for fiscal years and interim periods beginning after December 15, 2016. On July 9, 2015, the FASB decided to delay the effective date of this standard to annual reporting periods beginning after December 15, 2017. The FASB permitted early adoption of this standard, but with an adoption date no earlier than December 15, 2016, the original effective date of this ASU. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

Objectives for using derivative instruments			Embedded Derivatives. The Company is deemed to have foreign currency forward contracts embedded in certain of the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved. These embedded derivatives are separated from their host contracts and carried on the Company’s balance sheet at their fair value. The majority of these embedded derivatives arise as a result of the Company’s foreign subsidiaries pricing their customer contracts in the U.S. dollar. Economic Hedges of Embedded Derivatives. The Company uses foreign currency forward contracts to manage the foreign exchange risk associated with the Company’s embedded derivatives (“economic hedges of embedded derivatives”). Foreign Currency Forward and Option Contracts. The Company also uses foreign currency forward and options contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities. As a result of foreign currency fluctuations, the U.S. dollar equivalent values of the foreign currency-denominated assets and liabilities change.
