New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards With the exception of those discussed below, there have been no recent changes in accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”) or adopted by the Company during the three months ended April 30, 2016, that are of significance, or potential significance, to the Company. Accounting Standards Adopted Effective in the first quarter of fiscal 2017, Autodesk adopted FASB's Accounting Standards Update No. 2015-05 ("ASU 2015-05") regarding Subtopic 350-40, “Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this ASU provide guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments for ASU 2015-05 were prospectively applied and did not have a material impact on Autodesk's consolidated financial statements. Effective in the first quarter of fiscal 2017, Autodesk adopted FASB's Accounting Standards Update No. 2015-07 ("ASU 2015-07") regarding ASC Topic 820, "Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)." The amendments in ASU 2015-07 remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also limit certain disclosures to investments for which the entity has elected to measure at fair value using the net asset value per share practical expedient. The amendments were applied retrospectively by removing from the fair value hierarchy any investments for which fair value is measured using the net asset value per share practical expedient. Adoption did not have a material impact on Autodesk's consolidated financial statements. Recently Issued Accounting Standards In March 2016, the FASB issued Accounting Standards Update No. 2016-09 ("ASU 2016-09") regarding ASC Topic 718, “Improvements to Employee Share-Based Payment Accounting.” The amendments in ASU 2016-09 simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards, and classification on the statement of cash flows. Additionally, the amendments allow an entity to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures as they occur. Using a modified retrospective approach, the amendments will be effective for Autodesk’s fiscal year beginning February 1, 2018 unless Autodesk elects early adoption. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 ("ASU 2016-02") regarding ASC Topic 842, "Leases." The amendments in this ASU require balance sheet recognition of lease assets and lease liabilities by lessees for leases classified as operating leases, with an optional policy election to not recognize lease assets and lease liabilities for leases with a term of 12 months or less. The amendments also require new disclosures, including qualitative and quantitative requirements, providing additional information about the amounts recorded in the financial statements. ASU 2016-02 will be effective for Autodesk’s fiscal year beginning February 1, 2019 unless Autodesk elects early adoption. The amendments require a modified retrospective approach with optional practical expedients. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption. In January 2016, the FASB issued Accounting Standards Update No. 2016-01 ("ASU 2016-01") regarding ASC Topic 825-10, "Financial Instruments - Overall." The amendments address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments, and require equity securities to be measured at fair value with changes in fair value recognized through net income. The amendments also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment for impairment quarterly at each reporting period. The amendments in ASU 2016-01 are effective for annual and interim periods beginning after December 15, 2017. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with prospective adoption of the amendments related to equity securities without readily determinable fair values existing as of the date of adoption. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 ("ASU 2014-09") regarding ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2014-09 provides principles for recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14 to defer the effective date by one year with early adoption permitted as of the original effective date. ASU 2014-09 will be effective for Autodesk’s fiscal year beginning February 1, 2018 unless we elect the earlier date of February 1, 2017. In addition, the FASB issued ASU 2016-08, ASU 2016-10, and ASU 2016-12 in March 2016, April 2016, and May 2016, respectively, to help provide interpretive clarifications on the new guidance in ASC Topic 606. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.
