Basis of Presentation | BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared from the records of West Marine, Inc. and its subsidiaries (collectively, the “Company”) in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments (consisting only of normal recurring items) necessary to fairly state the financial position, results of operations and cash flows for the interim periods presented, have been included. The condensed consolidated balance sheet at December 31, 2016 presented herein has been derived from the audited consolidated financial statements of the Company that were included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Form 10-K”). These unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, for the fiscal year ended December 31, 2016 that were included in the 2016 Form 10-K. Accounting policies followed by the Company are described in Note 1 in the audited consolidated financial statements for the year ended December 31, 2016 . Certain information and disclosures normally included in the notes to annual financial statements prepared in accordance with GAAP have been omitted for purposes of the condensed consolidated interim financial statements presented herein. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The results of operations for the 13-week period ended April 1, 2017 are not necessarily indicative of the results to be expected for any other interim period or for the fiscal year ending December 30, 2017 . Historically, the Company's revenues and net income are higher in the second and third quarters and are lower in the first and fourth quarters of the fiscal year. The increase in revenues and earnings, principally during the period from April through August, is representative of the peak months for boat buying, usage and maintenance in most of the Company's retail markets. The Company's fiscal year consists of 52 or 53 weeks, ending on the Saturday closest to December 31. The 2017 fiscal year and 2016 fiscal year consist of 52 weeks ending on December 30, 2017 and December 31, 2016 , respectively. All quarters of both fiscal years 2017 and 2016 consist of 13 weeks. All references to years relate to fiscal years rather than calendar years. Cash and Cash Equivalents The Company's cash and cash equivalents consist of cash on hand, bank deposits and amounts in transit from banks for customer credit card and debit card transactions. As of April 1, 2017 , December 31, 2016 and April 2, 2016 , cash balances were $47.0 million , $76.1 million and $22.4 million , respectively. Reportable Segment West Marine is an omni-channel retail organization operating one reporting segment in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting . The metrics used by the Company's Chief Executive Officer (as the chief operating decision maker) to assess the performance of the Company and the process he uses to allocate resources focus on viewing the business as a single, integrated business. The Company has integrated systems and has commingled sales channel payroll expense, inventories, merchandise procurement activities, and distribution networks to concentrate its strategy as an omni-channel retailer. Revenues from customers are derived from merchandise sales, and the Company does not rely on any individual major customer. The Company considers its merchandise expansion strategy to be important to the future success of the Company and is providing the following product category information. Net revenues from the Company's merchandise mix for the periods ended April 1, 2017 and April 2, 2016 , respectively, is reflected in the table below: 13 Weeks Ended Net Revenues from: April 1, 2017 April 2, 2016 Core boating products 79.1 % 79.2 % Merchandise expansion products 20.9 % 20.8 % Total 100.0 % 100.0 % The Company considers core boating products to be maintenance-related products, electronics, sailboat hardware, anchors/docking/moorings, engine systems, safety, electrical, plumbing, boats, outboards, ventilation, deck hardware/fasteners, navigation, trailering, seating/boat covers and barbecues/appliances. The Company considers its merchandise expansion products to be apparel, footwear, clothing accessories, fishing, watersports, paddlesports, coolers, bikes and cabin/galley. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients In May 2014, FASB issued an accounting standards update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the revenue recognition requirements in ASC Topic 605 , Revenue Recognition, and requires entities to recognize revenue in a way that depicts 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, FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which deferred the effective date of ASU 2014-09 to December 15, 2017 for annual reporting periods beginning after that date. FASB also approved permitting early adoption of the standard, but not before the original effective date of December 15, 2016. The Company did not early adopt the standard; therefore, the new standard will be effective for the Company's 2018 fiscal year. The standard permits the use of either the full retrospective or modified retrospective approach. The Company currently expects to adopt the new standard using the modified retrospective approach. In April 2016, FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , which clarifies the following two aspects of Topic 606: identifying performance obligations; and licensing implementation guidance. The Company did not early adopt the standard; therefore, the new standard will be effective for the Company's 2018 fiscal year. The Company is currently assessing and evaluating the new standard and has not yet concluded whether the adoption of ASU 2016-10 will have a material impact on the Company's consolidated financial statements. The Company currently expects to adopt an accounting policy to account for shipping and handling activities that occur after the customer has obtained control of a good as an activity to fulfill the promise to transfer the good, rather than as an additional promised service. This guidance does not represent a change from current practice for the Company. The Company does not have any license or royalty revenue. In May 2016, FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , which focuses on clarifying the guidance on assessing collectability, presentation of sales taxes, non-cash consideration, and completed contracts and contract modification at transition. The Company did not early adopt the standard; therefore, the new standard will be effective for the Company's 2018 fiscal year. The Company has not yet concluded whether the adoption of ASU 2016-12 will have a material impact on its consolidated financial statements. Consistent with its current accounting policy, the Company currently expects to exclude amounts collected from customers for all sales (and other similar) taxes from the transaction price. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842) , which is intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet for leases with a term of more than 12 months. In addition, the update will require additional disclosures regarding key information about leasing arrangements. Under existing guidance, operating leases with a term of more than 12 months are not recorded as lease assets and lease liabilities on the balance sheet. The update will be effective for the Company beginning in the first quarter of fiscal year 2019, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this accounting guidance on its consolidated financial statements. The Company expects the adoption of this accounting guidance to result in an increase in lease assets and a corresponding increase in lease liabilities on its consolidated balance sheets. In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which is intended to decrease the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this update provide guidance on specific cashflow issues. The amendments in ASU 2016-15 are effective for the Company for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, and should be applied using the retrospective transition method for each period presented. Early adoption is permitted, but all amendments must be adopted in the same period. The Company is not planning to early adopt and is currently evaluating the impact that the amendments will have on its consolidated financial statements. In October 2016, FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory . The effective date for ASU 2016-16 is for fiscal years beginning after December 15, 2017. ASU 2016-16 is applied on a modified retrospective basis and the Company will recognize any effects of adoption in the retained earnings at the beginning of its 2018 fiscal year. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements. In March 2016, FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which is intended to simplify several aspects of the accounting for share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted the new guidance the first quarter of 2017 on a prospective basis. The impact to the Company was not significant. The Company does not have any previously unrecognized windfalls. Tax shortfalls on awards vesting in the period were recorded in the income statement and the Company will continue to estimate forfeitures each period. There was no impact to the statement of cash flows, as the Company will continue to report all tax-related cash flows resulting from share based payments as operating activities, and all cash payments made to taxing authorities on behalf of employees, based on shares withheld to cover tax obligations, are reported as financing activities. |
