Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Basis of Presentation The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments necessary for a fair presentation for each of the periods presented. The results of operations for interim periods are not necessarily indicative of results to be achieved for full fiscal years or other interim periods. Deckers Outdoor Corporation (the Company) is a global leader in designing, marketing and distributing innovative footwear, apparel, and accessories developed for both everyday casual lifestyle use and high performance activities. The Company’s business is seasonal, with the highest percentage of UGG® (UGG) brand net sales occurring in the quarters ending September 30 and December 31 and the highest percentage of Teva® (Teva) and Sanuk® (Sanuk) brands net sales occurring in the quarters ending March 31 and June 30 of each year. Net sales of the other brands do not have a significant seasonal impact on the Company. The Company sells its products through domestic retailers and international distributors and retailers, as well as directly to end-user consumers through the Direct-to-Consumer (DTC) reporting segment. Independent third parties manufacture all of the Company's products. As contemplated by the SEC under Rule 10-01 of Regulation S-X, the accompanying unaudited condensed consolidated financial statements and accompanying notes have been condensed and do not contain certain information that will be included in the Company’s annual audited consolidated financial statements and accompanying notes thereto. See the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K, for the fiscal year ended March 31, 2016, filed with the SEC on May 31, 2016 (Annual Report on Form 10-K) for further information. Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in accordance with United States generally accepted accounting principles (US GAAP) requires management to make estimates and assumptions that affect the amounts reported in these unaudited condensed consolidated financial statements and accompanying notes. Management bases these estimates and assumptions upon historical experience, existing and known circumstances, authoritative accounting pronouncements and other factors that management believes to be reasonable. Significant areas requiring the use of management's estimates relate to inventory write-downs, accounts receivable allowances, returns liabilities, stock-based compensation, impairment assessments, depreciation and amortization, income tax liabilities, uncertain tax positions and income taxes receivable, the fair value of financial instruments, and the fair values of acquired intangibles, assets and liabilities. Actual results could differ materially from these estimates. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which requires 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 ASU will replace most existing revenue recognition guidance in US GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. On August 12, 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers, which provides for a one-year deferral of the effective date of ASU No. 2014-09, as well as early application, which will be effective for the Company on April 1, 2018. In March 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how to apply the implementation guidance related to principal versus agent considerations within ASU No. 2014-09. The Company is evaluating the effect that these ASUs will have on its condensed consolidated financial statements and related disclosures. The Company has not yet selected a transition method, nor has it determined the effect of the standard on its ongoing financial reporting. However, the adoption of the new revenue standard is not expected to have a material impact on the Company's condensed consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires an entity to present debt issuance costs on the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. Prior to the issuance of the standard, debt issuance costs were required to be presented in the balance sheet as a deferred charge (i.e., an asset). On August 18, 2015, the FASB issued ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which allows an entity to continue to present debt issuance costs related to line of credit arrangements as deferred charges. These ASUs were effective for the Company on April 1, 2016. The Company's adoption of ASU No. 2015-03 and ASU No. 2015-15 has not had and is not expected to have a material impact on the Company’s condensed consolidated financial statements or related disclosures. In April 2015, the FASB issued ASU No. 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, which clarifies whether a cloud computing arrangement should be treated as a software license or a service contract. Customers that have a cloud computing arrangement that includes a software license are required to account for the software license element of the arrangement consistent with the acquisition of other software licenses. Customers that have a cloud computing arrangement that does not include a software license are required to account for the arrangement as a service contract. This ASU was effective for the Company on April 1, 2016. The Company's adoption of ASU No. 2015-05 has not had and is not expected to have a material impact on the Company’s condensed consolidated financial statements or related disclosures. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, which changed the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. US GAAP currently requires that, at each financial statement date, entities measure inventory at the lower of cost or market, most commonly the current replacement cost. This ASU is effective for the Company on April 1, 2017, with early adoption permitted. The Company is evaluating the effect that ASU No. 2015-11 will have on its condensed consolidated financial statements and related disclosures, but it is not expected to have a material impact. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, which requires an entity to classify deferred tax assets and liabilities as noncurrent on the balance sheet. Prior to the issuance of the standard, deferred tax assets and liabilities were required to be separated into current and noncurrent amounts on the basis of the classification of the related asset or liability. This ASU was effective for the Company on April 1, 2017, with early adoption permitted. The Company prospectively adopted this ASU as of March 31, 2016 in its Annual Report on Form 10-K. The adoption of ASU No. 2015-17 did not have a material impact on the Company’s condensed consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new standard requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous US GAAP. A lessee should recognize in the balance sheet a liability to make lease payments (the lease liability) at fair value and an offsetting right-of-use asset representing its right to use the underlying asset for the lease term. When measuring assets and liabilities arising from a lease, a lessee (and a lessor) should include payments to be made in optional periods only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. Similarly, optional payments to purchase the underlying asset should be included in the measurement of lease assets and lease liabilities only if the lessee is reasonably certain to exercise that purchase option. This ASU is effective for the Company on April 1, 2019. The Company is evaluating the effect that the adoption of this ASU No. 2016-02 will have on its condensed consolidated financial statements and related disclosures. Since the Company utilizes operating leases for most of its facilities and retail stores, it is anticipated that adoption of this ASU will have a material impact on its balance sheet presentation. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which requires an entity to recognize excess tax benefits and certain tax deficiencies of employee share-based payment awards in the income statement instead of in additional paid-in-capital when the awards vest or are settled, and present excess tax benefits as an operating activity on the statement of cash flows instead of as a financing activity. This ASU also allows entities to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, and to make a policy election to either estimate the number of awards that are expected to vest or to account for forfeitures as they occur. In addition, the cash paid by an entity to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation is required to be classified as a financing activity on its statement of cash flows. This ASU is effective for the Company on April 1, 2017, with early adoption permitted. The Company is evaluating the effect that the adoption of this ASU No. 2016-09 will have on its condensed consolidated financial statements and related disclosures, but it is not expected to have a material impact.
