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, 2018 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 judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Examples of such estimates include provisions for warranty, uncollectible accounts receivable, inventory obsolescence, sales returns, and tax contingencies and estimates related to the Tax Act enacted in December 2017, and estimates on the valuation of share-based awards and recoverability of long-lived assets and investments. Actual results may materially differ from these estimates. On an ongoing basis, the Company reviews its estimates to ensure that these estimates appropriately reflect changes in its business or as new information becomes available. Recent Accounting Standards In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The amendments in this ASU will remove, modify or add to the disclosure requirements for fair value measurements in Accounting Standards Codification ("ASC") Topic 820, "Fair Value Measurement" ("Topic 820"). The amendments are effective for all entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt the removed or modified disclosures upon the issuance of this ASU and may delay adoption of the additional disclosures required for public companies until the effective date of this ASU. The Company is currently evaluating the impact this ASU will have on its consolidated condensed financial statements and disclosures. Adoption of New Accounting Standards On January 1, 2019, the Company adopted ASU No. 2016-02, "Leases (Topic 842)" "(Topic 842)" utilizing the modified retrospective adoption method, and the targeted improvement amendments under ASU 2018-11, which allows entities to change their date of initial application to January 1, 2019 and not restate the comparative prior periods in the period of adoption when transitioning to Topic 842. Under Topic 842, the Company elected the transition relief package to not reassess (1) any expired or existing contracts that are leases or contain leases, (2) the classification of any expired or existing leases and (3) initial direct costs for any existing leases. Therefore, the consolidated condensed financial statements for 2019 are presented under the new standard, while the comparative periods presented are not adjusted and continue to be reported in accordance with the Company's historical accounting policy. This standard requires all lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, for all leases with a term greater than 12 months. The adoption of the new lease standard had a significant impact on the Company's consolidated condensed balance sheets due to the recognition of $133,632,000 of right-of-use assets for operating leases and a corresponding lease obligation of $136,290,000. The accounting for finance leases is substantially unchanged. The adoption of Topic 842 did not have a material impact on the Company's lease classification or on its statements of operations and liquidity. Additionally, adoption of Topic 842 did not have a material impact on the Company’s debt-covenant compliance under its current agreements. See to Note 2, "Leases," for information regarding the Company's adoption of Topic 842 and the Company's undiscounted future lease payments and the timing of those payments. On January 1, 2019, the Company adopted ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The new standard refined and expanded hedge accounting for both financial (e.g., interest rate) and commodity risks to create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also targeted improvements to simplify the application of hedge accounting guidance. Based on the Company's assessment, this new standard did not have a material impact on the Company's consolidated condensed financial statements and disclosures.
