Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. (collectively with its consolidated subsidiaries referred to as "Equinix," the "Company," "we," "our," or "us") 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. In the preparation of our condensed consolidated financial statements, we have considered potential impacts of the COVID-19 pandemic on our critical and significant accounting estimates. There was no significant impact to our condensed consolidated financial statements. We will continue to evaluate the nature and extent of the potential impacts to our business and our condensed consolidated financial statements. Our condensed consolidated balance sheet data as of December 31, 2021 has been derived from audited consolidated financial statements as of that date. Our condensed 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 ("U.S. GAAP"). For further information, refer to the Consolidated Financial Statements and Notes thereto included in our Form 10-K as filed with the SEC on February 18, 2022. 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 our acquisition of two data centers in Mumbai, India from the India operations of GPX Global Systems, Inc. ("GPX India") from September 1, 2021. All intercompany accounts and transactions have been eliminated in consolidation. Income Taxes We elected to be taxed as a real estate investment trust for U.S. federal income tax purposes ("REIT") beginning with our 2015 taxable year. As a result, we may deduct the dividends paid to our stockholders from taxable income generated by our REIT and qualified REIT subsidiaries ("QRSs"). Our dividends paid deduction generally eliminates the U.S. federal taxable income of our REIT and QRSs, resulting in no U.S. federal income tax due. However, our domestic taxable REIT subsidiaries ("TRSs") are subject to U.S. corporate income taxes on any taxable income generated by them. In addition, our foreign operations are subject to local income taxes regardless of whether the foreign operations are operated as QRSs or TRSs. We accrue 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 our operating performance, tax law changes and future business acquisitions. Our effective tax rates were 18.2% and 17.3% for the three months ended March 31, 2022 and 2021, respectively. Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-08 Business Combinations ("Topic 805"): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The ASU requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. We are currently evaluating the extent of the impact of this ASU, but do not expect the adoption of this standard to have a significant impact on our condensed consolidated financial statements. Accounting Standards Adopted Income Taxes In December 2019, FASB issued 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 generally accepted accounting principles ("GAAP") for other areas of Topic 740 by clarifying and amending existing guidance. 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. On January 1, 2021, we adopted this ASU on a prospective basis and the adoption of this standard did not have an impact on our condensed consolidated financial statements. Debt with Conversion and Other Options In August 2020, FASB issued ASU 2020-06: Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The ASU simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock and modifies the disclosure requirement for the convertible instruments. Additionally, this ASU improves the consistency of EPS calculations by eliminating the use of the treasury stock method to calculate diluted EPS for convertible instruments and clarifies certain areas under the current EPS guidance. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted at the beginning of the fiscal year after December 15, 2020. On January 1, 2022, we adopted this ASU on a prospective basis and the adoption of this standard did not have an impact on our condensed consolidated financial statements.
