Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation and Organization | BASIS OF PRESENTATION AND ORGANIZATION Nature of the business: Columbia Sportswear Company is a global leader in the design, sourcing, marketing, and distribution of outdoor and active lifestyle apparel, footwear, accessories, and equipment. Principles of consolidation: The Consolidated Financial Statements include the accounts of Columbia Sportswear Company, its wholly owned subsidiaries and entities in which it maintains a controlling financial interest (the "Company"). All intercompany balances and transactions have been eliminated in consolidation. Estimates and assumptions: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. 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 Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates and assumptions. Some of these more significant estimates relate to revenue recognition, including sales returns and claims from customers, allowance for doubtful accounts, excess, slow-moving and close-out inventories, product warranty, long-lived and intangible assets, goodwill, income taxes, and stock-based compensation. Changes affecting comparability: Effective January 1, 2016, the Company early-adopted Accounting Standards Update ("ASU") No. 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplified how several aspects of share-based payments are accounted for and presented in the financial statements. Under previous guidance, excess tax benefits and deficiencies from stock-based compensation arrangements were recorded in equity when the awards vested or were settled. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies in the Consolidated Statements of Operations, resulting in the recognition of excess tax benefits of $6,082,000 and $5,499,000 in income tax expense, rather than in paid-in capital, for the years ended December 31, 2017 and 2016, respectively. If we had retrospectively adopted this guidance, we would have recognized excess tax benefits of $7,925,000 in income tax expense, rather than in paid-in capital, for the year ended December 31, 2015. In addition, under ASU 2016-09, excess income tax benefits from stock-based compensation arrangements are classified as cash flow from operations, rather than as cash flow from financing activities. The Company elected to apply the cash flow classification guidance of ASU 2016-09 prospectively, resulting in an increase to operating cash flow of $6,227,000 and $5,538,000 for the years ended December 31, 2017 and 2016, respectively, and the year ended December 31, 2015 has not been adjusted. The Company elected to continue to estimate the number of stock-based awards expected to vest, as permitted by ASU 2016-09, rather than electing to account for forfeitures as they occur. ASU 2016-09 requires excess tax benefits and deficiencies to be prospectively excluded from assumed future proceeds in the calculation of diluted shares, resulting in an increase in diluted weighted average shares outstanding of 159,387 and 240,016 shares for the years ended December 31, 2017 and 2016, respectively.
