Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of Acushnet Holdings Corp. (the “Company”), its wholly owned subsidiaries and a variable interest entity (“VIE”) in which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to current year presentation. Certain information in footnote disclosures normally included in annual financial statements has been condensed or omitted for the interim periods presented in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and U.S. GAAP. The year-end balance sheet data was derived from audited financial statements; however, the accompanying interim notes to the unaudited condensed consolidated financial statements do not include all disclosures required by U.S. GAAP. In the opinion of management, the financial statements contain all normal and recurring adjustments necessary to state fairly the financial position and results of operations of the Company. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of results to be expected for the full year ending December 31, 2018 , nor were those of the comparable 2017 period representative of those actually experienced for the full year ended December 31, 2017 . These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes for the fiscal year ended December 31, 2017 included in its Annual Report on Form 10-K filed with the SEC on March 7, 2018 . Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and judgments that affect reported amounts of assets, liabilities, shareholders’ equity, net sales and expenses, and the disclosure of contingent assets and liabilities in its unaudited condensed consolidated financial statements. Actual results could differ from those estimates. Variable Interest Entities VIEs are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities independently, or (ii) have equity holders that do not have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the entity’s expected losses, or the right to receive the entity’s expected residual returns. The Company consolidates a VIE when it is the primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) through its interests in the VIE, the obligation to absorb expected losses or the right to receive expected benefits from the VIE that could potentially be significant to the VIE. The Company consolidates the accounts of Acushnet Lionscore Limited, a VIE which is 40% owned by the Company. The sole purpose of the VIE is to manufacture the Company’s golf footwear and as such, the Company is deemed to be the primary beneficiary. The Company has presented separately on its consolidated balance sheets, to the extent material, the assets of its consolidated VIE that can only be used to settle specific obligations of its consolidated VIE and the liabilities of its consolidated VIE for which creditors do not have recourse to its general credit. The general creditors of the VIE do not have recourse to the Company. Certain directors of the noncontrolling entities have guaranteed the credit lines of the VIE, for which there were no outstanding borrowings as of March 31, 2018 and December 31, 2017 . In addition, pursuant to the terms of the agreement governing the VIE, the Company is not required to provide financial support to the VIE. Cash and Restricted Cash Cash held in Company checking accounts is included in cash. Book overdrafts not subject to offset with other accounts with the same financial institution are classified as accounts payable. The Company classifies as restricted certain cash that is not available for use in its operations. As of March 31, 2018 and December 31, 2017 , the amount of restricted cash included in cash and restricted cash on the balance sheet was $2.4 million and $2.3 million , respectively. Accounts Receivable As of March 31, 2018 and December 31, 2017 , the allowance for doubtful accounts was $10.3 million and $10.0 million , respectively. Foreign Currency Translation and Transactions Foreign currency transaction gains included in selling, general and administrative expense were $2.0 million and $2.3 million for the three months ended March 31, 2018 and 2017 , respectively. Recently Adopted Accounting Standards Revenue from Contracts with Customers On January 1, 2018, the Company adopted the new accounting standard Accounting Standards Codification ("ASC") 606, " Revenue from Contracts with Customers" ("ASC 606") and all the related amendments (the “new revenue standard”) using the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to opening retained earnings (Note 2 ). The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. Income Statement—Reporting Comprehensive Income On January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2018‑02, “Income Statement—Reporting Comprehensive Income (Topic 220) —Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” As a result of the adoption of the amendments in this update, the Company recorded a reclassification from accumulated other comprehensive loss to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (Note 10 ). The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. Financial Instruments - Recognition and Measurement On January 1, 2018, the Company adopted ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"). ASU 2016-01 supersedes the guidance to classify equity securities with readily determinable fair values into different categories (that is, trading or available-for-sale) and requires equity securities to be measured at fair value with changes in the fair value recognized through net income, among other items. As a result of the adoption of the amendments in this update, the Company recorded a reclassification of unrealized gains of $2.1 million from accumulated other comprehensive loss to retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. Compensation—Retirement Benefits On January 1, 2018, the Company adopted ASU 2017‑07, “Compensation — Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post Retirement Benefit Cost” ("ASU 2017-07"). ASU 2017‑07 requires that an employer report the service cost component of net periodic pension and net periodic post retirement cost in the same line item as other compensation costs arising from services rendered by the employees during the period. It also requires the other components of net periodic pension and net periodic postretirement benefit cost to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. Additionally, only the service cost component is eligible for capitalization. As a result of the adoption of the amendments in this update, the Company recorded a reclassification of the non-service cost component of net periodic benefit cost of $0.2 million from selling, general and administrative expense to other (income) expense, net on the consolidated statement of operations for the three months ended March 31, 2017. The adoption of this standard also resulted in the restatement of the Company's segment operating income for the three months ended March 31, 2017 (Note 15 ). The Company also adopted the following standards during 2018, none of which had a material impact to the Company's financial statements or financial statement disclosures: Standard Effective Date ASU 2017‑09 Compensation—Stock Compensation: Scope of Modification Accounting January 1, 2018 ASU 2017‑01 Business Combinations: Clarifying the Definition of a Business January 1, 2018 ASU 2016‑16 Income Taxes: Intra-Entity Transfers of Assets other than Inventory January 1, 2018 ASU 2016‑15 Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments January 1, 2018 Recently Issued Accounting Standards Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities In August 2017, the Financial Accounting Standards Board ("FASB") issued ASU 2017‑12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ” ("ASU 2017-12"). The amendments in this update expand and refine hedge accounting guidance and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. ASU 2017-12 also simplifies the application of hedge accounting guidance, hedge documentation requirements and the assessment of hedge effectiveness. ASU 2017‑12 is effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued or made available for issuance. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption. The adoption of this standard is not expected to have a material impact on the consolidated financial statements. Intangibles—Goodwill and Other — Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU 2017‑04, “ Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment ” ("ASU 2017-04"). ASU 2017‑04 removes the second step of the goodwill impairment test. Instead an entity will perform a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. ASU 2017‑04 is effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on the consolidated financial statements. Leases In February 2016, the FASB issued ASU 2016‑02, “ Leases ,” which will require lessees to recognize right‑of‑use assets and lease liabilities for leases which were formerly classified as operating leases. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. While the Company is still in the process of completing its analysis on the complete impact this ASU will have on its consolidated financial statements and related disclosures, it does expect the adoption of this standard will have a material impact on its consolidated financial statements. |
