Accounting Policies [Abstract]
Basis of Presentation	Note 1. Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared by Callaway Golf Company (the “Company” or “Callaway Golf”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “Commission”). Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the Commission. These consolidated condensed financial statements, in the opinion of management, include all the normal and recurring adjustments necessary for the fair presentation of the financial position, results of operations and cash flows for the periods and dates presented. Interim operating results are not necessarily indicative of operating results for the full year. The preparation of financial statements in conformity with 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions. Recent Accounting Standards In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." This amendment is intended to simplify several aspects of the accounting for share-based payment transactions, including (i) the recognition of excess tax benefits or deficiencies in the operating statement when compensatory stock awards are vested and settled, and the presentation of these tax benefits or deficiencies as an operating cash outflow on the statement of cash flows, (ii) the option to withhold the maximum statutory tax rate on the settlement of compensatory stock without triggering liability accounting, as well as presenting the shares withheld for the settlement of these taxes as a financing outflow on the statement of cash flows, and (iii) the option to elect a change in the accounting policy to account for forfeitures as they occur. The amendment is effective for annual periods beginning after December 15, 2016, and interim periods therein. The Company adopted this ASU using the modified retrospective transition method with respect to the recognition of excess tax benefits in the consolidated condensed statement of operations. The adoption did not result in a cumulative-effect adjustment to equity as of January 1, 2017. The amendment related to the cash flow presentation of shares acquired to satisfy the Company's minimum tax withholding requirements in connection with the settlement of compensatory stock was applied retrospectively as a financing outflow. The adoption had no impact to any periods presented on the consolidated condensed statement of cash flows as these cash outflows have historically been presented as a financing activity. The Company elected not to change its accounting policy on the recognition of estimated forfeitures. In March 2016, the FASB issued ASU No. 2016-04, "Liabilities—Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products." The amendment clarifies when it is acceptable to recognize the unredeemed portion of prepaid gift cards into income, and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated condensed financial statements and disclosures. As of March 31, 2017, the Company had $1,235,000 of deferred revenue related to unredeemed gift cards. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently evaluating the impact this ASU will have on its consolidated condensed financial statements and disclosures. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments─Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendment requires (i) equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, (ii) public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and (iii) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). This amendment eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost. This amendment is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. As of March 31, 2017, the Company had an investment in Topgolf International, Inc. of $48,997,000 that was accounted for at cost in accordance with ASC Topic 325, “Investments—Other” (see Note 8). If there are any observable price changes related to this investment or a similar investment of the same issuer in fiscal years beginning after December 15, 2017, the Company would be required to write this investment up or down to its estimated fair value, which could have a significant effect on the Company's financial position and results of operations. In July 2015, the FASB issued ASU No. 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory." This amendment requires an entity to measure in-scope inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. For public business entities, this ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this amendment did not have a material impact on the Company's consolidated condensed financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers: (Topic 606)." This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). This ASU will supersede the revenue recognition requirements in Topic 605, "Revenue Recognition," and most industry-specific guidance. In addition, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer (e.g., assets within the scope of Topic 360, "Property, Plant, and Equipment," and intangible assets within the scope of Topic 350, "Intangibles-Goodwill and Other") are amended to be consistent with the guidance on recognition and measurement (including the constraint on revenue) in this ASU. The core principle of the guidance is that an entity should recognize revenue to depict 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. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted only for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company does not intend to early adopt the new guidance, and is in the early stages of evaluating the amended revenue recognition guidance in Topic 606. As such, as of March 31, 2017, the Company is unable at this time to provide information on how the adoption of this ASU will affect the Company’s consolidated condensed financial statements and disclosures.
