Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Pursuant to these rules and regulations, we have condensed or omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present our financial position, results of operations and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 1, 2017 on file with the SEC (our “Annual Report”).
Recent Accounting Pronouncements	Recently Adopted Accounting Guidance On January 26, 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment, which eliminated step two from the goodwill impairment test. In assessing impairment of goodwill, if it is concluded that it is more likely than not that the carrying amount of a reportable segment exceeds its fair value during the qualitative assessment, a one-step goodwill impairment test will be performed. If it is concluded during the quantitative test that the carrying amount of a reportable segment exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reportable segment. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. In the first quarter of 2018, we early adopted ASU 2017-04. The standard did not have an impact to our qualitative assessment for goodwill impairment that we performed in the second quarter of fiscal 2018. Significant Accounting Policies There have been no other material changes to our significant accounting policies during the nine months ended August 31, 2018, as compared to the significant accounting policies described in our Annual Report. Recent Accounting Pronouncements Not Yet Effective On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either the full retrospective or modified retrospective transition method. The updated standard is effective for us in the first quarter of fiscal 2019. We expect to adopt this updated standard in the first quarter of fiscal 2019 on a modified retrospective basis. We are currently evaluating the effect that the updated standard will have on our condensed consolidated financial statements and related disclosures. While we are continuing to assess all potential impacts of the new standard, we believe there should not be a material change to the amount of consolidated revenues on an annual basis. We expect revenue related to our cloud offerings, including Creative Cloud and Document Cloud for business enterprises, individuals and teams, to remain substantially unchanged. When sold with cloud-enabled services, Creative Cloud and Document Cloud require a significant level of integration and interdependency with software and the individual components are not considered distinct. Revenue for these offerings will continue to be recognized over the period in which the cloud services are provided. We believe the most significant revenue-related impact relates to our accounting for arrangements that include on-premise term-based software licenses bundled with maintenance and support. Under current GAAP, the revenue attributable to these software licenses is recognized ratably over the term of the arrangement because vendor-specific objective evidence (“VSOE”) does not exist for the undelivered maintenance and support element as it is not sold separately. The requirement to have VSOE for undelivered elements to enable the separation of revenue for the delivered software licenses is eliminated under the new standard. Accordingly, under the new standard we will be required to recognize as revenue a portion of the arrangement fee upon delivery of the software licenses and potentially classify such revenue as “product” instead of “subscription” revenue on the income statement. We offer on-premise term-based software licenses bundled with maintenance and support as a deployment model for certain offerings within our Digital Experience, Digital Media, and Publishing business units. We do not expect these arrangements to have a material impact to revenue reported in annual reporting periods subsequent to adoption, however they may result in a material balance sheet impact on the date of adoption due to the application of the modified retrospective transition method. The modified retrospective method requires upon adoption that we recognize the impact of applying the new standard to contracts that are not completed at the date of initial adoption, but do not restate prior financial statements. We will record a cumulative effect of initially applying the provisions of the new standard as an adjustment to increase the opening retained earnings balance and reduce the opening deferred revenue balance. Further, some of our enterprise agreements allow our customers to renew on-premise term-based licenses on a monthly basis. Revenue associated with these arrangements would be recognized monthly. Other expected impacts to our policies and disclosures include: earlier recognition of revenue for certain contracts due to the elimination of contingent revenue limitations, an unbilled receivable balance on our balance sheets, the requirement to estimate variable consideration for certain arrangements, increased allocation of revenue to and from professional services and other offerings, and changes to our financial statement disclosures such as remaining performance obligations. Under current GAAP, we expense costs related to the acquisition of revenue-generating contracts as incurred. Under the new standard, we will be required to capitalize certain costs incremental to contract acquisition and amortize them over the expected period of benefit. There may be a material balance sheet impact at the period of adoption to capitalize costs of obtaining the contract as an asset, with a corresponding adjustment to opening retained earnings at the date of initial adoption. Additionally, we may have to record related deferred income taxes. We continue to evaluate the magnitude of the impact and the period over which these capitalized costs will be amortized. Due to the complexity of certain of our contracts, the actual accounting treatment required under the new standard for these arrangements may be dependent on contract-specific terms and therefore may vary in some instances. On February 24, 2016, the FASB issued ASU No. 2016-02, Leases, requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases with a lease term of twelve months or less. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and allows for the application of the new guidance at the beginning of the earliest comparative period presented or at the adoption date. The updated standard is effective for us beginning in the first quarter of fiscal 2020 and we do not plan to early adopt. We are currently evaluating the effect that the updated standard will have on our condensed consolidated financial statements and related disclosures. On August 28, 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging, requiring expanded hedge accounting for both non-financial and financial risk components and refining the measurement of hedge results to better reflect an entity's hedging strategies. The updated standard also amends the presentation and disclosure requirements and changes how entities assess hedge effectiveness. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition with a cumulative effect adjustment recorded to opening retained earnings as of the initial adoption date. The updated standard is effective for us beginning in the first quarter of fiscal 2020 and we do not plan to early adopt. We are currently evaluating the effect that the updated standard will have on our condensed consolidated financial statements and related disclosures. With the exception of the new standards discussed above, there have been no other recent accounting pronouncements or changes in accounting pronouncements during the nine months ended August 31, 2018, as compared to the recent accounting pronouncements described in our Annual Report, that are of significance or potential significance to us.
