Accounting Policies [Abstract] |
Basis of Presentation and Preparation | Basis of Presentation and Preparation—The unaudited condensed consolidated financial statements of Fortinet, Inc. and its wholly owned subsidiaries (collectively, “we,” “us” or “our”) have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information, as well as the instructions to Form 10-Q pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements, and should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2019, contained in our Annual Report on Form 10-K filed with the SEC on February 26, 2020. In the opinion of management, all adjustments, which includes normal recurring adjustments, considered necessary for a fair presentation have been included. All intercompany balances, transactions and cash flows have been eliminated. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results for the full year or for any future periods. The condensed consolidated balance sheet as of December 31, 2019 is derived from the audited consolidated financial statements for the year ended December 31, 2019. For 2020, the amounts previously reported as Income taxes payable are included in Accrued liabilities. Prior periods have been reclassified to conform with current period presentation. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. There have been no material changes to our significant accounting policies as of and for the three months ended March 31, 2020.
Recently Adopted Accounting Standards and Recent Accounting Standards Not Yet Effective | Recently Adopted Accounting Standards Financial Instruments In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13—Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“Topic 326”), which provides guidance on how an entity should measure credit losses on financial instruments. The standard replaces the existing incurred loss model with an expected credit loss model for financial assets measured at amortized cost, including trade receivables, and requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The new approach to estimating credit losses (referred to as the current expected credit losses model) generally accelerates recognition of credit losses. We adopted Topic 326 on January 1, 2020 using the modified retrospective method. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. Cloud Computing In August 2018, the FASB issued ASU 2018-15—Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Accounting Standards Codification (“ASC”) Topic 350, Intangibles—Goodwill and Other, to determine which implementation costs to capitalize as assets or expense as incurred. We adopted ASU 2018-15 on January 1, 2020. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. Fair Value Measurements In August 2018, the FASB issued ASU 2018-13—Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements in ASC 820, Fair Value Measurement, as part of its disclosure framework project. We adopted ASU 2018-13 on January 1, 2020. The adoption of this standard did not have a material impact on our disclosures. Recent Accounting Standards Not Yet Effective Income Taxes In December 2019, the FASB issued ASU 2019-12—Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application and simplification of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for us beginning on January 1, 2021. Early adoption of the amendments is permitted. We are currently evaluating the impact of ASU 2019-12 on our condensed consolidated financial statements.
