Accounting Policies [Abstract]
Nature of Business and Basis of Presentation	1. Nature of Business and Basis of Presentation Nature of Business—Zumiez Inc., including its wholly owned subsidiaries, (the “Company,” “we,” “us,” “its” and “our”) is a leading multi-channel specialty retailer of apparel, footwear, accessories and hardgoods rooted in youth culture as expressed through music, art, fashion and action sports lifestyle for young men and women. At August 1, 2015, we operated 640 stores; 578 in the United States (“U.S.”), 40 in Canada and 22 in Europe. We operate under the names Zumiez and Blue Tomato. Additionally, we operate ecommerce websites at www.zumiez.com and www.blue-tomato.com. Fiscal Year—We use a fiscal calendar widely used by the retail industry that results in a fiscal year consisting of a 52- or 53-week period ending on the Saturday closest to January 31. Each fiscal year consists of four 13-week quarters, with an extra week added to the fourth quarter every five or six years. The six months ended August 1, 2015 and August 2, 2014 were 26-week periods. Basis of Presentation—The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited condensed consolidated financial statements include the accounts of Zumiez Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation. In our opinion, the unaudited condensed consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated balance sheets, operating results and cash flows for the periods presented. The financial data at January 31, 2015 is derived from audited consolidated financial statements, which are included in our Annual Report on Form 10-K for the year ended January 31, 2015, and should be read in conjunction with the audited consolidated financial statements and notes thereto. Interim results are not necessarily indicative of results for the full fiscal year due to seasonality and other factors. Use of Estimates—The preparation of financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. These estimates can also affect supplemental information disclosed by us, including information about contingencies, risk and financial condition. Actual results could differ from these estimates and assumptions. Segment Reporting—We identify our operating segments according to how our business activities are managed and evaluated. Our operating segments have been aggregated and are reported as one reportable segment based on the similar nature of products sold, production, merchandising and distribution processes involved, target customers and economic characteristics. Recent Accounting Standards— In July 2015, the Financial Accounting Standards Board (“FASB”) issued guidance simplifying the measurement of inventory. This standard requires entities that use inventory methods other than the last-in, first-out (LIFO) or retail inventory method to measure inventory at the lower of cost or net realizable value, which is defined as the estimated selling prices in the normal course of business, less reasonably predictable costs of completion, disposal, and transportation. We are required to adopt this guidance for the fiscal year beginning after December 31, 2016. We are currently evaluating the impact of this standard on our consolidated financial statements. In May 2015, the FASB issued guidance about a customer’s accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of 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 guidance is effective for the fiscal year beginning after December 15, 2015 and may be applied on either a prospective or retrospective basis. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In August 2014, the FASB issued new guidance which provides details on when and how to disclose going concern uncertainties. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year and to provide certain footnote disclosures if conditions or events raise substantial doubt about an entity’s ability to continue as a going concern. The new standard is effective for the fiscal year beginning after December 15, 2016, with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In May 2014, the FASB issued a comprehensive new revenue recognition standard. The new standard allows for a full retrospective approach to transition or a modified retrospective approach. This guidance was effective for fiscal years and interim periods within those years beginning after December 15, 2016. In August 2015, the FASB issued updated guidance deferring the effective date for the fiscal year beginning after December 15, 2017 and will permit early adoption of the standard, but not before the original effective date of December 15, 2016. We are currently evaluating the method of adoption we plan to use and the effect the standard is expected to have on our financial position, results of operations and cash flows.
