Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Acushnet Holdings Corp. (the “Company”), headquartered in Fairhaven, Massachusetts, is the global leader in the design, development, manufacture and distribution of performance-driven golf products. The Company has established positions across all major golf equipment and golf wear categories under its globally recognized brands of Titleist, FootJoy, Scotty Cameron and Vokey Design. Acushnet products are sold primarily to on-course golf pro shops and selected off-course golf specialty stores, sporting goods stores and other qualified retailers. The Company sells products primarily in the United States, Europe (primarily the United Kingdom, Germany, France and Sweden), Asia (primarily Japan, Korea, China and Singapore), Canada and Australia. Acushnet manufactures and sources its products principally in the United States, China, Thailand, the United Kingdom and Japan. Acushnet Holdings Corp. was incorporated in Delaware on May 9, 2011 as Alexandria Holdings Corp., an entity owned by Fila Korea Co., Ltd. (“Fila Korea”), a leading sport and leisure apparel and footwear company which is a public company listed on the Korea Exchange, and a consortium of investors (the “Financial Investors”). Acushnet Holdings Corp. acquired Acushnet Company, its operating subsidiary, from Beam Suntory, Inc. (at the time known as Fortune Brands, Inc.) (“Beam”) on July 29, 2011. On November 2, 2016, the Company completed an initial public offering of 19,333,333 shares of its common stock sold by selling stockholders at a public offering price of $17.00 per share. Upon the closing of the Company’s initial public offering, all remaining outstanding shares of the Company’s Series A redeemable convertible preferred stock (“Series A preferred stock”) were automatically converted into 11,556,495 shares of the Company’s common stock and the Company’s 7.5% convertible notes due 2021 (“convertible notes”) were automatically converted into 22,791,852 shares of the Company’s common stock. The underwriters of the Company’s initial public offering exercised their over-allotment option to purchase an additional 2,899,999 shares of common stock from the selling stockholders at the initial public offering price of $17.00 per share. Following the pricing of the initial public offering, Magnus Holdings Co., Ltd. (“Magnus”), a wholly-owned subsidiary of Fila Korea, purchased from the Financial Investors on a pro rata basis 14,818,720 shares of the Company’s common stock, resulting in Magnus holding a controlling ownership interest in the Company’s outstanding common stock. The 14,818,720 shares of the Company’s common stock sold by the Financial Investors were received upon the automatic conversion of certain of the Company’s outstanding convertible notes (Note 10 ) and Series A preferred stock (Note 15 ). The remaining outstanding convertible notes and Series A preferred stock automatically converted into shares of the Company’s common stock prior to the closing of the initial public offering. On October 14, 2016, the Company effected a nine -for-one stock split of its issued and outstanding shares of common stock and a proportional adjustment to the existing conversion ratios for its convertible notes, Series A preferred stock, and the exercise price for the common stock warrants and the strike price of stock-based compensation. Accordingly, all share and per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split and adjustment of the common stock warrant exercise price, and convertible notes and redeemable convertible preferred stock conversion ratios.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying 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 the Company, its wholly- owned subsidiaries and less than wholly-owned subsidiaries, including 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. Revision of Previously Issued Financial Statements During the fourth quarter of 2018 , the Company determined that in 2011 it did not record a required deferred income tax liability on the difference between the book and tax basis of intangible assets resulting from the 2011 acquisition of Acushnet Company. This deferred tax liability should have been remeasured during the fourth quarter of 2017 based upon the change in tax rates resulting from the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). The Company has corrected these errors as a revision to the previously issued financial statements. The correction of these errors resulted in a decrease in income tax expense of $6.6 million , an increase in net income of $6.6 million , an increase in comprehensive income of $6.6 million and an increase in both basic and diluted net income per common share of $0.09 for the year ended December 31, 2017 . The correction also resulted in a decrease in deferred income tax assets of $10.9 million , an increase in goodwill of $17.5 million , an increase in total assets of $6.6 million and an increase in total shareholders' equity of $6.6 million as of December 31, 2017 . The errors also resulted in a decrease in deferred income tax assets of $17.5 million and an increase in goodwill of $17.5 million as of December 31, 2016, which has been revised in the related footnotes. The impact of this revision has been reflected throughout these financial statements, including the related footnotes, and is not material to the consolidated financial statements for the year ended December 31, 2017 . Use of Estimates The preparation of the Company’s 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 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 VIE have guaranteed the credit lines of the VIE, for which there were no outstanding borrowings as of December 31, 2018 and 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. Noncontrolling Interests The ownership interest held by owners other than the Company in less than wholly-owned subsidiaries are classified as noncontrolling interests. The value attributable to the noncontrolling interests is presented on the consolidated balance sheets within shareholders' equity, separately from the equity attributable to the Company. Net income (loss) and comprehensive income (loss) attributable to noncontrolling interests are presented separately on the consolidated statements of operations and consolidated statements of comprehensive income, respectively. The Company's less than wholly-owned subsidiaries include a VIE, as discussed above, and PG Professional Golf which was acquired on October 1, 2018 (Note 22 ). 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. As of December 31, 2018 and 2017 , book overdrafts in the amount of $2.2 million and $2.9 million , respectively, were recorded in accounts payable. The Company classifies as restricted certain cash that is not available for use in its operations. As of December 31, 2018 and 2017 , the amount of restricted cash included in cash and restricted cash on the consolidated balance sheet was $2.0 million and $2.3 million , respectively. Concentration of Credit Risk and of Significant Customers Financial instruments that potentially expose the Company to concentration of credit risk are cash and accounts receivable. Substantially all of the Company's cash deposits are maintained at large, creditworthy financial institutions. The Company's deposits, at times, may exceed federally insured limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. As part of its ongoing procedures, the Company monitors its concentration of deposits with various financial institutions in order to avoid any undue exposure. As of December 31, 2018 and 2017 , the Company had $28.6 million and $44.7 million , respectively, in banks located outside the United States. The risk with respect to the Company's accounts receivable is managed by the Company through its policy of monitoring the creditworthiness of its customers to which it grants credit terms in the normal course of business. Inventories Inventories are valued at the lower of cost and net realizable value. Cost is determined using the first-in, first-out inventory method. The inventory balance, which includes material, labor and manufacturing overhead costs, is recorded net of an allowance for obsolete or slow moving inventory. The Company's allowance for obsolete or slow moving inventory contains estimates regarding uncertainties. Such estimates are updated each reporting period and require the Company to make assumptions and to apply judgment regarding a number of factors, including market conditions, selling environment, historical results and current inventory trends. See Note 5 for additional information. Property, Plant and Equipment Property, plant and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation is recorded on a straight-line basis over the estimated useful lives of the assets. Gains or losses resulting from disposals are included in income from operations. Betterments and renewals, which improve and extend the life of an asset, are capitalized. Maintenance and repair costs are expensed as incurred. Estimated useful lives of property, plant and equipment asset categories were as follows: Buildings and improvements 15 - 40 years Machinery and equipment 3 - 10 years Furniture, fixtures and computer hardware 3 - 10 years Computer software 1 - 10 years Leasehold and tenant improvements are amortized over the shorter of the lease term or the estimated useful lives of the assets. Certain costs incurred in connection with the development of the Company's internal-use software are capitalized. Internal-use software development costs are primarily related to the Company's enterprise resource planning system. Costs incurred in the preliminary stages of development are expensed as incurred. Internal and external costs incurred in the application development phase, if direct and incremental, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing performed to ensure the product is ready for its intended use. Costs such as maintenance and training are expensed as incurred. The capitalized internal-use software costs are included in property, plant and equipment and once the software is placed into service are amortized over the estimated useful life which ranges from three to ten years . See Note 6 for additional information. Long-Lived Assets A long-lived asset (including amortizing intangible assets) or asset group is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, the Company compares the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of the asset or asset group. The cash flows are based on the best estimate of future cash flows derived from the most recent business projections. If the carrying value exceeds the sum of the undiscounted cash flows, an impairment loss is recognized based on the excess of the asset's or asset group's carrying value over its fair value. Fair value is determined based on discounted expected future cash flows on a market participant basis. Any impairment charge would be recognized within operating expenses as a selling, general and administrative expense. The Company continually evaluates whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets may warrant revision or that the remaining balance may not be recoverable. These factors may include a significant deterioration of operating results, changes in business plans, or changes in anticipated cash flows. Goodwill and Indefinite-Lived Intangible Assets Goodwill and indefinite-lived intangible assets are not amortized but instead are measured for impairment at least annually, or more frequently when events or changes in circumstances indicate that the carrying amount of the asset may be impaired. Goodwill is assigned to reporting units for purposes of impairment testing. A reporting unit may be the same as an operating segment or one level below an operating segment. For purposes of assessing potential impairment, the Company compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is considered not impaired. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company records goodwill impairment in the amount of the excess of a reporting unit’s carrying value over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The fair value of the reporting units is determined using the income approach. The income approach uses a discounted cash flow analysis which involves applying appropriate discount rates to estimated future cash flows based on forecasts of sales, costs and capital requirements. Purchased intangible assets other than goodwill are amortized over their useful lives unless those lives are determined to be indefinite. Certain of the Company's trademarks have been assigned an indefinite life as the Company currently anticipates that these trademarks will contribute to its cash flows indefinitely. Indefinite-lived trademarks are reviewed for impairment annually and may be reviewed more frequently if indicators of impairment are present. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value. The Company measures the fair value of its trademarks using the relief-from-royalty method, which estimates the present value of royalty income that could be hypothetically earned by licensing the brand name to a third party over the remaining useful life. See Note 7 for additional information. The Company performs its annual impairment tests in the fourth quarter of each fiscal year. During the years ended December 31, 2018 , 2017 and 2016 , no impairment charges were recorded to goodwill or indefinite-lived intangible assets. Deferred Financing Costs The Company defers costs directly associated with acquiring third-party financing. These deferred costs are amortized as interest expense over the term of the related indebtedness. Deferred financing costs associated with the revolving credit facilities are included in other current and noncurrent assets and deferred financing costs associated with all other indebtedness are netted against long-term debt and capital lease obligations on the consolidated balance sheet. See Note 10 for additional information. Fair Value Measurements Certain assets and liabilities are carried at fair value under U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The Company’s derivative instrument assets and liabilities are carried at fair value determined according to the fair value hierarchy described above (Note 11 and 12 ). The carrying value of accounts receivable, accounts payable and accrued expenses approximates fair value due to the short-term nature of these assets and liabilities. The Company adopted the fair value measurement disclosures for nonfinancial assets and liabilities, such as goodwill and indefinite-lived intangible assets. In some instances where a market price is available, but the instrument is in an inactive or over-the-counter market, the Company consistently applies the dealer (market maker) pricing estimate and uses a midpoint approach on bid and ask prices from financial institutions to determine the reasonableness of these estimates. Assets and liabilities subject to this fair value valuation approach are typically classified as Level 2. See Note 12 for additional information. Pension and Other Postretirement Benefit Plans The Company provides U.S. and foreign defined benefit and defined contribution plans to certain eligible employees and postretirement benefits to certain retirees, including pensions, postretirement healthcare benefits and other postretirement benefits. Plan assets and obligations are measured using various actuarial assumptions, such as discount rates, rate of compensation increase, mortality rates, turnover rates and health care cost trend rates, as determined at each year end measurement date. The measurement of net periodic benefit cost is based on various actuarial assumptions, including discount rates, expected return on plan assets and rate of compensation increase, which are determined as of the prior year measurement date. The determination of the discount rate is generally based on an index created from a hypothetical bond portfolio consisting of high-quality fixed income securities with durations that match the timing of expected benefit payments. The expected return on plan assets is determined based on several factors, including adjusted historical returns, historical risk premiums for various asset classes and target asset allocations within the portfolio. Adjustments made to the historical returns are based on recent return experience in the equity and fixed income markets and the belief that deviations from historical returns are likely over the relevant investment horizon. Actual cost is also dependent on various other factors related to the employees covered by these plans. The effects of actuarial deviations from assumptions are generally accumulated and, if over a specified corridor, amortized over the remaining service period of the employees. The cost or benefit of plan changes, such as increasing or decreasing benefits for prior employee service (prior service cost), is deferred and included in expense on a straight-line basis over the average remaining service period of the related employees. The Company's actuarial assumptions are reviewed on an annual basis and modified when appropriate. To calculate the U.S. pension and postretirement benefit plan expense in 2018 and 2017, the Company applied the individual spot rates along the yield curve that correspond with the timing of each future cash outflow for the benefit payments in order to calculate interest cost and service cost. Prior to 2017, the service cost and interest cost components were determined using a single weighted-average discount rate. The change does not affect the measurement of the total benefit plan obligations, as the change in the service cost and interest cost offsets in the actuarial gains and losses recorded in other comprehensive income (loss). The Company changed to the new method to provide a more precise measure of service and interest cost by improving the correlation between the projected benefit cash flows and the discrete spot yield curve rates. The Company accounted for this change as a change in estimate prospectively beginning in 2017. See Note 13 for additional information. Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between consolidated financial statement carrying amounts and tax basis amounts at enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is recorded to reduce deferred income tax assets when it is more-likely-than-not that such assets will not be realized. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. The Company records liabilities for uncertain income tax positions based on the two step process. The first step is recognition, where an individual tax position is evaluated as to whether it has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, no tax benefit is recorded. For tax positions that have met the recognition threshold in the first step, the Company performs the second step of measuring the benefit to be recorded. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized on ultimate settlement. The actual benefits ultimately realized may differ from the estimates. In future periods, changes in facts, circumstances, and new information may require the Company to change the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recorded in income tax expense and liability in the period in which such changes occur. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes on the consolidated statements of income. Beam has indemnified certain tax obligations that relate to periods during which Fortune Brands, Inc. owned Acushnet Company (Note 23 ). These estimated tax obligations are recorded in accrued taxes and other noncurrent liabilities, and the related indemnification receivable is recorded in other noncurrent assets on the consolidated balance sheet. Any changes in the value of these specifically identified tax obligations are recorded in the period identified in income tax expense and the related change in the indemnification asset is recorded in other expense, net on the consolidated statement of operations. See Note 14 for additional information. On December 22, 2017, the U.S. enacted the 2017 Tax Act. The 2017 Tax Act contains a new law that subjects the Company to a tax on Global Intangible Low-Taxed Income (“GILTI”), beginning in 2018. GILTI is a tax on foreign income in excess of a deemed return on tangible assets of related foreign corporations. Companies subject to GILTI have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for temporary differences, including outside basis differences, expected to reverse as GILTI. The Company has elected to account for GILTI as a period cost. Cost of Goods Sold Cost of goods sold includes all costs to make products salable, such as inbound freight, purchasing and receiving costs, inspection costs and transfer costs. In addition, all depreciation expense associated with assets used to manufacture products and make them salable is included in cost of goods sold. Product Warranty The Company has defined warranties ranging from one to two years. Products covered by the defined warranty policies include all Titleist golf products, FootJoy golf shoes, and FootJoy golf outerwear. These product warranties generally obligate the Company to pay for the cost of replacement products, including the cost of shipping replacement products to its customers. The estimated cost of satisfying future warranty claims is accrued at the time the sale is recorded. In estimating future warranty obligations, the Company considers various factors, including its warranty policies and practices, the historical frequency of claims, and the cost to replace or repair products under warranty. See Note 8 for additional information. Advertising and Promotion Advertising and promotional costs are included in selling, general and administrative expense on the consolidated statement of operations and include product endorsement arrangements with members of the various professional golf tours, media placement and production costs (television, print and internet), tour support expenses and point-of-sale materials. Advertising production costs are expensed as incurred. Media placement costs are expensed in the month the advertising first appears. Product endorsement arrangements are expensed based upon the specific provisions of player contracts. Advertising and promotional expense was $192.2 million , $192.7 million and $196.0 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Selling Selling expenses including field sales, sales administration and shipping and handling costs are included in selling, general and administrative expense on the consolidated statement of operations. Shipping and handling costs included in selling expenses were $34.1 million , $32.5 million and $32.4 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Research and Development Research and development expenses include product development, product improvement, product engineering, and process improvement costs and are expensed as incurred. Foreign Currency Translation and Transactions Assets and liabilities denominated in foreign currency are translated into U.S. dollars at the actual rates of exchange at the balance sheet date. Revenues and expenses are translated at the average rates of exchange for the reporting period. The related translation adjustments are recorded as a component of accumulated other comprehensive loss. Transactions denominated in a currency other than the functional currency are re-measured into functional currency with resulting transaction gains or losses recorded as selling, general and administrative expense on the consolidated statement of operations. Foreign currency transaction gain (loss) included in selling, general and administrative expense was a loss of $1.9 million , a gain of $4.1 million and a gain of $1.2 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Derivative Financial Instruments All derivative instruments are recognized as either assets or liabilities on the consolidated balance sheet and are measured at fair value. If the derivative instrument is designated as a fair value hedge, the changes in the fair value of the derivative instruments and of the hedged item attributable to the hedged risk are recognized in earnings in the same period. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive loss and are recognized in the consolidated statement of operations when the hedged item affects earnings. Any portion of the change in fair value that is determined to be ineffective is immediately recognized in earnings. Cash flows from derivative financial instruments and the related hedged transactions are included in cash flows from operating activities. See Note 11 for additional information. Share-based Compensation The Company has a share-based compensation plan for board of directors, officers, employees, consultants and advisors of the Company. All awards granted under the plan are measured at fair value at the date of the grant. The Company issues share-based awards with service-based vesting conditions and performance-based vesting conditions. Awards with service-based vesting conditions are amortized as expense over the requisite service period of the award, which is generally the vesting period of the respective award. For awards with performance-based vesting conditions, the measurement of the expense is based on the Company’s level of achievement of performance metrics as defined in the applicable award agreements. The Company accounts for forfeitures in compensation expense when they occur. See Note 17 for additional information. Net Income per Common Share Net income per common share attributable to Acushnet Holdings Corp. is calculated under the treasury stock method. Prior to the conversion of the redeemable convertible preferred shares to common stock in connection with the Company’s initial public offering in 2016, the Company applied the two-class method to calculate its basic and diluted net income per common share attributable to Acushnet Holdings Corp., as its redeemable convertible preferred shares were participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. Net income per common share available to Acushnet Holdings Corp. was determined by allocating undistributed earnings between holders of common shares and redeemable convertible preferred shares, based on the participation rights of the preferred shares. Basic net income per common share attributable to Acushnet Holdings Corp. was computed by dividing the net income available to Acushnet Holdings Corp. by the basic weighted-average number of common shares outstanding during the period. Diluted net income per common share attributable to Acushnet Holdings Corp. was computed by dividing the net income available to Acushnet Holdings Corp. after giving effect to the diluted securities by the weighted-average number of dilutive shares outstanding during the period. See Note 20 for additional information. Recently Adopted Accounting Standards Revenue from Contracts with Customers On January 1, 2018, the Company adopted 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 3 ). 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, net of tax to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (Note 14 ). 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 (Note 18 ). 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, net of tax 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 Postretirement 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 $3.5 million and $1.7 million from cost of goods sold and operating expenses to other expense, net on the consolidated statement of operations for the years ended December 31, 2017 and 2016 , respectively (Notes 13 and 19 ). The adoption of this standard also resulted in the restatement of the Company's segment operating income for the years ended December 31, 2017 and 2016 (Note 21 ) and unaudited quarte

Revenue from Contract with Customer [Abstract]
Revenue	Revenue On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historic accounting under ASC 605, "Revenue Recognition" . The Company recorded a net reduction to opening retained earnings of $1.6 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to a promotional holiday program. The impact of applying ASC 606 was an increase in net sales of $4.3 million and an increase in cost of sales of $2.3 million for the year ended December 31, 2018 . Additionally, the Company reclassified the refund liability for expected returns from accounts receivable, net to accrued expenses and other liabilities and reclassified the value of inventory expected to be recovered related to sales returns from inventories to other assets as of December 31, 2018 . The refund liability for expected returns was $9.8 million and $13.5 million as of December 31, 2018 and 2017 , respectively. The value of inventory expected to be recovered related to sales returns was $5.7 million and $4.3 million as of December 31, 2018 and 2017 , respectively. The adoption of ASC 606 did not have any other material impacts to the financial statements. Accounting Policies Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied. The majority of the Company's contracts have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when control of the products has been transferred to the customer, generally at the time of shipment or delivery of products, based on the terms of the contract and the jurisdiction of the sale. Revenue is recognized in an amount that reflects the consideration the Company expects to be entitled to in exchange for the products. Revenue is recognized net of allowances for discounts and sales returns. Sales taxes and other similar taxes are excluded from revenue. Substantially all of the Company’s revenue is recognized at a point in time and relates to customers who are not engaged in a long-term supply agreement or any form of contract with the Company. Substantially all of sales are paid for on account with the majority of terms between 30 and 60 days , not to exceed one year . Costs associated with shipping and handling activities, such as merchandising, are included in selling, general and administrative expenses as revenue is recognized. The Company has made an accounting policy election to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. The Company reduces revenue by the amount of expected returns and records a corresponding refund liability in accrued expenses and other liabilities. The Company accounts for the right of return as variable consideration and recognizes a refund liability for the amount of consideration that it estimates will be refunded to customers. In addition, the Company recognizes an asset for the right to recover returned products in other assets on the consolidated balance sheets. Sales returns are estimated based upon historical rates of product returns, current economic trends and changes in customer demands as well as specific identification of outstanding returns. Contract Balances Accounts receivable, net, include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected. The allowance includes amounts for certain customers where a risk of default has been specifically identified as well as a provision for customer defaults when it is determined the risk of some default is probable and estimable, but cannot yet be associated with specific customers. The assessment of the likelihood of customer defaults is based on various factors, including credit risk assessments, length of time the receivables are past due, historical experience, customer specific information available to the Company and existing economic conditions. Customer Sales Incentives The Company offers sales-based incentive programs to certain customers in exchange for certain benefits, including prominent product placement and exclusive stocking by participating retailers. These programs typically provide qualifying customers with rebates for achieving certain purchase goals. The rebates can be settled in the form of cash or credits or in the form of free product. The rebates which are expected to be settled in the form of cash or credits are accounted for as variable consideration. The estimate of the variable consideration requires the use of assumptions related to the percentage of customers who will achieve qualifying purchase goals and the level of achievement. These assumptions are based on historical experience, current year program design, current marketplace conditions and sales forecasts, including considerations of the Company's product life cycles. The rebates which are expected to be settled in the form of product are estimated based upon historical experience and the terms of the customer programs and are accounted for as an additional performance obligation. Revenue will be recognized when control of the free products earned transfers to the customer at the end of the related customer incentive program, which generally occurs within one year . Control of the free products generally transfers to the customer at the time of shipment. Practical Expedients and Exemptions The Company expenses sales commissions when incurred because the amortization period is one year or less. These costs are recorded within selling, general and administrative expense on the consolidated statements of operations. The Company has elected the practical expedient to not disclose information about remaining performance obligations that have original expected durations of one year or less. Disaggregated Revenue In general, the Company's business segmentation is aligned according to the nature and economic characteristics of its products and customer relationships and provides meaningful disaggregation of each business segment's results of operations. See Note 21 for the Company's business segment disclosures, as well as a further disaggregation of net sales by geographical area.

Senior Secured Credit Facility On April 27, 2016, the Company entered into a senior secured credit facilities agreement arranged by Wells Fargo Bank, National Association which provided for (i) a $275.0 million multi‑currency revolving credit facility, initially including a $20.0 million letter of credit sublimit, a $25.0 million swing line sublimit, a C $25.0 million sublimit for Acushnet Canada, Inc., a £20.0 million sublimit for Acushnet Europe Limited and an alternative currency sublimit of $100.0 million for borrowings in Canadian dollars, euros, pounds sterling and Japanese yen (“revolving credit facility”), (ii) a $375.0 million term loan A facility and (iii) a $100.0 million delayed draw term loan A facility. The credit agreement allows for the incurrence of additional term loans or increases in the revolving credit facility in an aggregate principal amount not to exceed (i) $200.0 million plus (ii) an unlimited amount so long as the net average secured leverage ratio (as defined in the credit agreement) does not exceed 2.00 : 1.00 on a pro forma basis. On August 9, 2017 , the senior secured credit facilities agreement was amended to increase the letter of credit sublimit to $25.0 million , to increase the sublimit for Acushnet Canada Inc. to C $35.0 million and to increase the sublimit for Acushnet Europe Limited to £30.0 million . The revolving credit facility and term loan facilities mature on July 28, 2021 and are secured by certain assets, including inventory, accounts receivable, fixed assets and intangible assets of the Company. The credit agreement requires the Company to prepay outstanding term loans, subject to certain exceptions, with: • 100% of the net cash proceeds of all non‑ordinary course asset sales or other dispositions of property by the Company and its restricted subsidiaries (including insurance and condemnation proceeds, subject to de minimis thresholds), (1) if the Company does not reinvest those net cash proceeds in assets to be used in its business or to make certain other permitted investments, within 12 months of the receipt of such net cash proceeds or (2) if the Company commits to reinvest such net cash proceeds within 12 months of the receipt thereof, but does not reinvest such net cash proceeds within 18 months of the receipt thereof; and • 100% of the net proceeds of any issuance or incurrence of debt by the Company or any of its restricted subsidiaries, other than debt permitted under the credit agreement. The foregoing mandatory prepayments are used to reduce the installments of principal in such order: first, to prepay outstanding loans under the term loan A facility, the delayed draw term loan A facility and any incremental term loans on a pro rata basis in direct order of maturity and second, to prepay outstanding loans under the revolving credit facility. The Company may voluntarily repay outstanding loans under the credit agreement at any time without premium or penalty, other than customary “breakage” costs with respect to Eurodollar loans. Any optional prepayment of term loans will be applied as directed by the Company. The Company is required to make principal payments on the loans under the term loan facilities in quarterly installments in aggregate annual amounts equal to (i) 5.00% of the original principal amount for the first and second year after July 28, 2016, (ii) 7.50% of the original principal amount for the third and fourth year after July 28, 2016 and (iii) 10.0% of the original principal amount for the fifth year after July 28, 2016. The remaining outstanding amount is payable on July 28, 2021, the maturity date for the term loan facilities. Principal amounts outstanding under the revolving credit facility will be due and payable in full on July 28, 2021, the maturity date for the revolving credit facility. The applicable interest rate for the Canadian borrowings under the senior secured credit facility is based on the Canadian Dollar Offered Rate (“CDOR”) plus a margin ranging from 1.25% to 2.00% depending on the Net Average Total Leverage Ratio as defined in the credit agreement. The applicable interest for the swing line sublimit is the highest of (a) Federal Funds Rate plus 0.50% , (b) the Prime Rate and (c) the one-month London Interbank Offered Rate (“LIBOR”) rate plus 1.00% plus a margin ranging from 0.25% to 1.00% depending on the Net Average Total Leverage Ratio as defined in the credit agreement. The applicable interest rate for all remaining borrowings under the senior secured credit facilities is LIBOR plus a margin ranging from 1.25% to 2.00% depending on the Net Average Total Leverage Ratio as defined in the credit agreement or the highest of (a) the Federal Funds Rate plus 0.50% , (b) the Prime Rate and (c) the one month LIBOR rate plus 1.00% plus a margin ranging from 0.25% to 1.00% depending on the Net Average Total Leverage Ratio as defined in the credit agreement. Interest on borrowings under the credit agreement is payable (1) on the last day of any interest period with respect to Eurodollar borrowings with an applicable interest period of three months or less, (2) every three months with respect to Eurodollar borrowings with an interest period of greater than three months or (3) on the last business day of each March, June, September and December with respect to base rate borrowings and swing line borrowings. In addition, beginning with the date of the initial funding under the credit agreement, the Company is required to pay a commitment fee on any unutilized commitments under the revolving credit facility and the new delayed draw term loan A facility. The initial commitment fee rate is 0.30% per annum and ranges from 0.20% to 0.35% based upon a leverage‑based pricing grid. The Company is also required to pay customary letter of credit fees. The Company’s credit agreement was signed and became effective on April 27, 2016 and initial funding under the credit agreement occurred on July 28, 2016. The proceeds of the $375.0 million term loan A facility, borrowings of C $4.0 million (equivalent to approximately $3.0 million ) under the revolving credit facility and cash on hand of $23.6 million were used to repay all amounts outstanding under the secured floating rate notes and certain former working credit facilities. The secured floating rate notes, certain former working credit facilities and the former senior revolving credit facility were terminated. During the first quarter of 2017, the Company drew down $100.0 million on the delayed draw term loan A facility and $47.8 million under the revolving credit facility to substantially fund the equity appreciation rights (“EAR") plan payout (Note 17 ). The interest rate applicable to the term loan A facility and delayed draw term loan A facility as of December 31, 2018 and 2017 was 4.02% and 3.32% , respectively. The weighted average interest rate applicable to the outstanding borrowings under the revolving credit facility was 4.44% as of December 31, 2017 . A change of control is an event of default under the credit agreement which could result in the acceleration of all outstanding indebtedness and the termination of all commitments under the credit agreement and would allow the lenders under the credit agreement to enforce their rights with respect to the collateral granted. A change of control occurs if any person (other than certain permitted parties, including Fila Korea) becomes the beneficial owner of 35% or more of the outstanding common stock of the Company. On September 22, 2017, Magnus entered into a loan agreement (the “New Magnus Loan Agreement”) with certain Korean financial institutions (the “New Magnus Lenders”) which provides for (i) three year term loans in an aggregate amount of Korean Won 399.2 billion (equivalent to approximately $358.1 million , using an exchange rate of $1.00 = Korean Won 1,114.76 as of December 31, 2018 ) (the “New Magnus Term Loans”) and (ii) a revolving credit loan of Korean Won 10.0 billion (equivalent to approximately $9.0 million , using an exchange rate of $1.00 = Korean Won 1,114.76 as of December 31, 2018 ) (the “New Magnus Revolving Loan” and, together with the New Magnus Term Loans, the “New Magnus Loans”). The New Magnus Loans are secured by a pledge on all of the Company's common stock owned by Magnus, which consists of 39,345,151 shares (the “Magnus Shares”), or 52.6% of the Company's outstanding common stock as of December 31, 2018 . Under the New Magnus Loan Agreement, Magnus is required to maintain a specified Loan-to-Value ratio (“LTV Ratio”). If the LTV Ratio exceeds 75% , Magnus will be in breach of the New Magnus Loan agreement. If Magnus does not cure the breach in 60 days, the lenders will have a right to accelerate the maturity of the New Magnus Loan. If Magnus fails to pay the amount due on the New Magnus Loan at maturity or upon acceleration, the lenders can foreclose on the pledged shares of the Company’s common stock, which may result in the sale of up to 52.6% of the Company’s common stock as of December 31, 2018 . The credit agreement contains a number of covenants that, among other things, restrict the ability of the U.S. Borrower and its restricted subsidiaries to (subject to certain exceptions), incur, assume, or permit to exist additional indebtedness or guarantees; incur liens; make investments and loans; pay dividends, make payments, or redeem or repurchase capital stock or make prepayments, repurchases or redemptions of certain indebtedness; engage in mergers, liquidations, dissolutions, asset sales, and other dispositions (including sale leaseback transactions); amend or otherwise alter terms of certain indebtedness or certain other agreements; enter into agreements limiting subsidiary distributions or containing negative pledge clauses; engage in certain transactions with affiliates; alter the nature of the business that it conducts or change its fiscal year or accounting practices. Certain exceptions to these covenants are determined based on ratios that are calculated in part using the calculation of Adjusted EBITDA. The credit agreement also restricts the ability of Acushnet Holdings Corp. to engage in certain mergers or consolidations or engage in any activities other than permitted activities. The Company’s credit agreement contains certain customary affirmative and restrictive covenants, including, among others, financial covenants based on the Company’s leverage and interest coverage ratios. The credit agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations to be immediately due and payable. On June 7, 2018, Acushnet Company, Acushnet Canada Inc. and Acushnet Europe Limited, as borrowers, and the Company and certain other subsidiaries of the Company, as guarantors, entered into an amendment with Wells Fargo Bank, National Association and certain other lenders to the Company’s senior secured credit facilities agreement. Pursuant to the amendment, the restrictive covenant governing the payment of dividends, the making of certain other payments and the redemption or repurchase of capital stock was amended to permit an additional $150.0 million of such payments, redemptions and/or repurchases, subject to certain conditions. In connection with amending the senior secured credit facilities, the Company incurred approximately $0.4 million in fees and expenses, which were recorded as debt issuance costs and will be recognized as interest expense over the term of the senior secured credit facilities. As of December 31, 2018 , the Company was in compliance with all covenants under the credit agreement. As of December 31, 2018 , the Company had available borrowings under its revolving credit facility of $263.6 million after giving effect to $11.4 million of outstanding letters of credit. Convertible Notes Prior to the initial public offering, the Company had outstanding convertible notes with an aggregate principal amount of $362.5 million . All outstanding convertible notes were converted into common stock in conjunction with the Company’s initial public offering (Note 1 ). Upon conversion, all accrued but unpaid interest on the principal of the convertible notes was paid to each holder of the convertible notes. The Company recorded interest expense related to the convertible notes of $22.6 million during the year ended December 31, 2016 . Secured Floating Rate Notes On July 28, 2016, outstanding borrowings under the secured floating rate notes of $375.0 million were repaid in full using the proceeds from the senior secured credit facility and the secured floating rate notes were terminated. Senior Revolving and Term Loan Facilities As of June 30, 2016, the Company had repaid all amounts outstanding under the senior revolving and term loan facilities and the facilities were terminated. Other Short-Term Borrowings The Company has certain unsecured facilities available through its subsidiaries. The weighted average interest rate applicable to the outstanding borrowings was 3.25% and 0.73% as of December 31, 2018 and 2017 , respectively. As of December 31, 2018 , the Company had available borrowings remaining under these local credit facilities of $62.6 million . Letters of Credit As of December 31, 2018 and 2017 , there were outstanding letters of credit related to agreements, including the Company's Senior Secured Credit Facility, totaling $15.5 million and $14.3 million , respectively, of which $12.4 million and $11.2 million was secured, respectively. These agreements provided a maximum commitment for letters of credit of $29.2 million as of both December 31, 2018 and 2017 . Payments of Debt Obligations due by Period As of December 31, 2018 , principal payments due on outstanding long-term debt obligations, excluding capital leases, were as follows: (in thousands) Year ending December 31, 2019 $ 35,625 2020 38,594 2021 310,625 2022 — 2023 — Thereafter — Total $ 384,844

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company principally uses derivative financial instruments to reduce the impact of changes in foreign currency exchange rates and interest rate fluctuations. The principal derivative financial instruments the Company enters into are foreign exchange forward contracts and interest rate swaps. Additionally, prior to the exercise of the final annual call option by Fila Korea in July 2016, the Company had outstanding bonds with common stock warrants for the purchase of the Company’s common stock. The Company does not enter into derivative financial instruments contracts for trading or speculative purposes. Foreign Exchange Derivative Instruments Foreign exchange derivative instruments are foreign exchange forward contracts primarily used to hedge currency fluctuations for transactions denominated in a foreign currency, thereby limiting currency risk that would otherwise result from changes in exchange rates. The periods of the foreign exchange forward contracts correspond to the periods of the forecasted transactions, which do not exceed 24 months subsequent to the latest balance sheet date. The primary foreign exchange forward contracts pertain to the U.S. dollar, the Japanese yen, the British pound sterling, the Canadian dollar, the Korean won and the Euro. The gross U.S. dollar equivalent notional amount outstanding of all foreign exchange forward contracts designated under hedge accounting as of December 31, 2018 and 2017 was $312.8 million and $278.9 million , respectively. The Company also enters into foreign exchange forward contracts to mitigate the change in fair value of specific assets and liabilities which do not qualify as hedging instruments under U.S. GAAP. Accordingly, these undesignated instruments are recorded at fair value as a derivative asset or liability with the corresponding change in fair value recognized in selling, general and administrative expense, together with the re-measurement gain or loss from the hedged asset or liability. There were no outstanding foreign exchange forward contracts not designated under hedge accounting as of December 31, 2018 and 2017 . Interest Rate Derivative Instruments During 2018, the Company entered into interest rate swap contracts to reduce the impact of variability in interest rates. Under the contracts, the Company pays fixed and receives variable rate interest, in effect converting a portion of its variable rate debt to fixed rate debt. The interest rate swap contracts are accounted for as cash flow hedges. As of December 31, 2018 , the notional value of the Company's outstanding interest rate swap contracts was $185.0 million . As of December 31, 2017 , there were no outstanding interest rate swap contracts. Impact on Financial Statements The fair value of hedge instruments recognized on the consolidated balance sheets was as follows: (in thousands) December 31, December 31, Balance Sheet Location Hedge Instrument Type Other current assets Foreign exchange forward $ 6,116 $ 4,675 Other noncurrent assets Foreign exchange forward 1,015 562 Accrued expenses and other liabilities Foreign exchange forward 578 6,360 Interest rate swap 526 — Other noncurrent liabilities Foreign exchange forward 161 276 Interest rate swap 925 — The hedge instrument gain (loss) recognized in accumulated other comprehensive loss, net of tax was as follows: Gain (Loss) Recognized in Other Comprehensive Loss Year ended December 31, (in thousands) 2018 2017 2016 Type of hedge Foreign exchange forward $ 8,148 $ (15,558 ) $ 7,014 Interest rate swap (1,926 ) — — $ 6,222 $ (15,558 ) $ 7,014 Gains and losses on derivative instruments designated as cash flow hedges are reclassified from other comprehensive income (loss) at the time the forecasted transaction impacts the income statement. Based on the current valuation, the Company expects to reclassify a net gain of $6.0 million related to foreign exchange derivative instruments from accumulated other comprehensive loss, net of tax into cost of goods sold and a net loss of $0.5 million related to interest rate derivative instruments from accumulated other comprehensive loss, net of tax into interest expense, net during the next 12 months (Note 19 ). The hedge instrument gain (loss) recognized on the consolidated statements of operations was as follows: Gain (Loss) Recognized in Statement of Operations Year ended December 31, (in thousands) 2018 2017 2016 Location of gain (loss) in statement of operations Cost of goods sold $ (1,410 ) $ 1,329 $ 5,194 Selling, general and administrative expense 1,665 (2,732 ) (917 ) Interest expense, net (476 ) — — $ (221 ) $ (1,403 ) $ 4,277 Credit Risk The Company enters into derivative contracts with major financial institutions with investment grade credit ratings and is exposed to credit losses in the event of non-performance by these financial institutions. This credit risk is generally limited to the unrealized gains in the derivative contracts. However, the Company monitors the credit quality of these financial institutions and considers the risk of counterparty default to be minimal. Bonds with Common Stock Warrants Prior to the exercise of the final annual call option by Fila Korea in July 2016, the Company had outstanding bonds with common stock warrants for the purchase of the Company’s common stock at an exercise price of $11.11 per share. The Company classified the warrants to purchase common stock as a liability on its consolidated balance sheet as the warrants were free‑standing financial instruments that could result in the issuance of a variable number of the Company’s common shares. The warrants were initially recorded at fair value on grant date, and were subsequently re‑measured to fair value at each reporting date. The Company categorized the common stock warrants derivative liability as Level 3 as there were significant unobservable inputs used in the underlying valuations. Changes in the fair value of the common stock warrants were recognized as other expense, net on the consolidated statement of operations (Note 19 ). In July 2016, Fila Korea exercised its annual call option to purchase common stock warrants held by the holders of the bonds and exercised such warrants at the exercise price of $11.11 per share, or $34.5 million in the aggregate. The Company used the proceeds received from Fila Korea’s exercise of the common stock warrants to redeem the outstanding bonds payable.

Rabbi trust assets are used to fund certain retirement obligations of the Company. The assets underlying the Rabbi trust are equity and fixed income exchange‑traded funds. Deferred compensation program assets and liabilities represent a program where select employees can defer compensation until termination of employment. Effective July 29, 2011 , this program was amended to cease all employee compensation deferrals and provided for the distribution of all previously deferred employee compensation. The program remains in effect with respect to the value attributable to the employer match contributed prior to July 29, 2011 . Foreign exchange derivative instruments are foreign exchange forward contracts primarily used to hedge currency fluctuations for transactions denominated in a foreign currency (Note 11 ). The Company uses the mid‑price of foreign exchange forward rates as of the close of business on the valuation date to value each foreign exchange forward contract at each reporting period. Interest rate derivative instruments are contracts used to hedge the interest rate fluctuations of the Company's variable rate debt (Note 11 ). The valuation for the interest rate swap is calculated as the net of the discounted future cash flows of the pay and receive legs of the swap. Mid-market interest rates on the valuation date are used to create the forward curve for floating legs and discount curve.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits	Pension and Other Postretirement Benefits The Company has various pension and post-employment plans which provide for payment of benefits to certain eligible employees, mainly commencing between the ages of 50 and 65 , and for payment of certain disability benefits. After meeting certain qualifications, eligible employees acquire a vested right to future benefits. The benefits payable under the plans are generally determined on the basis of an employee's length of service and/or earnings.

The expected actuarial (gain) loss that will be amortized from accumulated other comprehensive loss into net periodic benefit cost in the next fiscal year is a loss of $1.0 million for the pension benefit plans and a gain of $1.5 million for the postretirement benefit plans. Components of net periodic benefit cost were as follows: Pension Benefits Postretirement Benefits Year ended December 31, (in thousands) 2018 2017 2016 2018 2017 2016 Components of net periodic benefit cost Service cost $ 9,067 $ 9,217 $ 9,763 $ 657 $ 955 $ 888 Interest cost 11,897 11,832 12,356 490 713 779 Expected return on plan assets (13,041 ) (12,006 ) (12,189 ) — — — Curtailment income (97 ) — — — — — Settlement expense 4,982 2,740 1,148 — — — Amortization of net (gain) loss 1,687 804 471 (1,540 ) (601 ) (912 ) Amortization of prior service cost (credit) 175 175 175 (137 ) (137 ) (163 ) Net periodic benefit cost (credit) $ 14,670 $ 12,762 $ 11,724 $ (530 ) $ 930 $ 592 The non-service cost components of net periodic benefit cost (credit) are included in other expense, net in the consolidated statement of operations (Note 19 ). The weighted average assumptions used to determine benefit obligations at December 31, 2018 and 2017 were as follows: Pension Benefits Postretirement Benefits 2018 2017 2018 2017 Discount rate 4.25 % 3.62 % 4.27 % 3.61 % Rate of compensation increase 4.00 % 4.01 % N/A N/A The weighted average assumptions used to determine net periodic benefit cost for the years ended December 31, 2018 , 2017 and 2016 were as follows: Pension Benefits Postretirement Benefits 2018 2017 2016 2018 2017 2016 Discount rate 3.62 % 4.17 % 4.16 % 3.61 % 4.08 % 4.30 % Expected long-term rate of return on plan assets 5.77 % 5.77 % 6.23 % N/A N/A N/A Rate of compensation increase 4.01 % 4.02 % 4.07 % N/A N/A N/A The assumed healthcare cost trend rates used to determine benefit obligations and net periodic benefit cost for postretirement benefits as of and for the years ended December 31, 2018 , 2017 and 2016 were as follows: 2018 2017 2016 Healthcare cost trend rate assumed for next year 6.25%/9.00% 5.50%/8.50% 5.50%/9.00% Rate that the cost trend rate is assumed to decline (the ultimate trend rate) 4.50 % 4.50 % 4.50 % Year that the rate reaches the ultimate trend rate 2027 2024 2024 Assumed healthcare cost trend rates have a significant effect on the amounts reported for the postretirement benefits. A one-percentage-point change in assumed healthcare cost trend rates would have the following effects: 2018 2017 (in thousands) One-Percentage Point Increase One-Percentage Point Decrease One-Percentage Point Increase One-Percentage Point Decrease Effect on total of service cost and interest cost $ 72 $ (64 ) $ 73 $ (65 ) Effect on projected benefit obligation 632 (572 ) 665 (598 ) Plan Assets Pension assets by major category of plan assets and the type of fair value measurement as of December 31, 2018 were as follows: (in thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Asset category Individual securities Fixed income $ 1,682 $ — $ 1,682 $ — Commingled funds Measured at net asset value 215,062 — — — $ 216,744 $ — $ 1,682 $ — Pension assets by major category of plan assets and the type of fair value measurement as of December 31, 2017 were as follows: (in thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Asset category Individual securities Fixed income $ 1,794 $ — $ 1,794 $ — Commingled funds Measured at net asset value 232,066 — — — $ 233,860 $ — $ 1,794 $ — Pension assets include fixed income securities and commingled funds. Fixed income securities are valued at daily closing prices or institutional mid-evaluation prices provided by independent industry-recognized pricing sources. Commingled funds are not traded in active markets with quoted prices and as a result, are valued using the net asset values provided by the administrator of the fund. The investments underlying the net asset values are based on quoted prices traded in active markets. In accordance with ASU 2015-7, “Fair Value Measurement: Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent)”, the Company has elected the practical expedient to exclude assets measured at net asset value from the fair value hierarchy. The Company's investment strategy is to optimize investment returns through a diversified portfolio of investments, taking into consideration underlying plan liabilities and asset volatility. Asset allocations are based on the underlying liability structure and local regulations. All retirement asset allocations are reviewed periodically to ensure the allocation meets the needs of the liability structure. Master trusts were established to hold the assets of the Company's U.S. defined benefit plans. During the year ended December 31, 2018 , the U.S. defined benefit plan asset allocation of these trusts targeted a return-seeking investment allocation of 50% to 76% and a liability-hedging investment allocation of 24% to 50% . During the year ended December 31, 2017 , the U.S. defined benefit plan asset allocation of these trusts targeted a return-seeking investment allocation of 64% to 76% and a liability-hedging investment allocation of 24% to 36% . Return-seeking investments include equities, real estate, high yield bonds and other instruments. Liability-hedging investments include assets such as corporate and government fixed income securities. The Company's future expected blended long-term rate of return on plan assets of 5.84% is determined based on long-term historical performance of plan assets, current asset allocation, and projected long-term rates of return. Estimated Contributions The Company expects to make pension contributions of approximately $25.9 million during 2019 based on current assumptions as of December 31, 2018 . Estimated Future Retirement Benefit Payments The following retirement benefit payments, which reflect expected future service, are expected to be paid as follows: (in thousands) Pension Benefits Postretirement Benefits Year ending December 31, 2019 $ 28,898 $ 721 2020 18,536 849 2021 20,064 1,007 2022 20,266 1,138 2023 23,730 1,210 Thereafter 125,482 7,180 $ 236,976 $ 12,105 The estimated future retirement benefit payments noted above are estimates and could change significantly based on differences between actuarial assumptions and actual events and decisions related to lump sum distribution options that are available to participants in certain plans. International Plans Pension coverage for certain eligible employees of the Company's international subsidiaries is provided, to the extent deemed appropriate, through separate defined benefit pension plans. The international defined benefit pension plans are included in the tables above. As of December 31, 2018 and 2017 , the international pension plans had total projected benefit obligations of $43.9 million and $53.6 million , respectively, and fair values of plan assets of $44.0 million and $53.6 million , respectively. The majority of the plan assets are invested in equity securities. The net periodic benefit cost related to international plans was $0.4 million , $0.9 million and $1.0 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The expected actuarial loss that will be amortized from accumulated other comprehensive loss into net periodic benefit cost in the next fiscal year is $0.1 million . Defined Contribution Plans The Company sponsors a number of defined contribution plans and company contributions related to these plans are determined under various formulas. Company contributions to defined contribution plans amounted to $16.5 million , $13.8 million and $13.0 million for the years ended December 31, 2018 , 2017 and 2016 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21% , eliminating certain deductions, imposing a mandatory one-time tax (“Transition Tax”) on accumulated earnings of foreign subsidiaries as of 2017, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. The 2017 Tax Act also enhanced and extended through 2026 the option to claim accelerated depreciation deductions on qualified property. In accordance with the 2017 Tax Act, the Company recorded a provisional tax expense of approximately $7.8 million in the fourth quarter of 2017, the period in which the legislation was enacted. This amount was primarily comprised of the remeasurement of federal net deferred tax assets resulting from the permanent reduction in the U.S. statutory corporate tax rate to 21% from 35% of approximately $4.0 million , the Transition Tax on the accumulated earnings of foreign subsidiaries of the Company of approximately $8.6 million , offset by the release of the deferred tax liability previously recorded on unremitted earnings of $4.8 million . Prior year information within this note has been revised. See further discussion of the impact of these revisions included in Note 2 - Revision of Previously Issued Financial Statements. Additionally, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the 2017 Tax Act. December 22, 2018 marked the end of the measurement period for purposes of SAB 118. As such, the Company has completed its analysis, based upon currently available legislative updates, proposed regulations, and other administrative guidance issued related to the 2017 Tax Act, which resulted in an additional tax expense in the fourth quarter of 2018 of $10.3 million and a total tax expense of $13.9 million for the year ended December 31, 2018 . The Company has determined that its undistributed earnings for most of its foreign subsidiaries are not permanently reinvested. The Company has provided for withholding taxes on all unremitted earnings, as required.

The following table represents a reconciliation of the activity related to the unrecognized tax benefits, excluding accrued interest and penalties: (in thousands) 2018 2017 2016 Unrecognized tax benefits at beginning of year $ 11,049 $ 11,347 $ 13,120 Gross additions - prior year tax positions — — 1,960 Gross additions - current year tax positions 801 1,159 747 Gross reductions - prior year tax positions (91 ) (348 ) (4,457 ) Gross reductions - Acquired tax positions settled with tax authorities (113 ) (1,241 ) — Impact of change in foreign exchange rates — 132 (23 ) Unrecognized tax benefits at end of year $ 11,646 $ 11,049 $ 11,347 As of December 31, 2018 , 2017 and 2016 , the unrecognized tax benefits of $11.6 million , $11.0 million and $11.3 million , respectively, would affect the Company's future effective tax rate if recognized. The Company does not anticipate a material change in unrecognized tax benefits within the next 12 months. As of December 31, 2018 , 2017 and 2016 , the Company had unrecognized tax benefits included in the amounts above of $5.0 million , $4.9 million and $5.9 million , respectively, related to periods prior to the Company's acquisition of Acushnet Company and as such, are indemnified by Beam. As of December 31, 2018 , 2017 and 2016 , the Company recognized a liability of $3.3 million , $2.7 million and $2.3 million , respectively for interest and penalties, of which $3.0 million , $2.7 million and $1.8 million is indemnified by Beam. Prior to the Company's acquisition of Acushnet Company, Acushnet Company or its subsidiaries filed certain combined tax returns with Beam. Those and other subsidiaries' income tax returns are periodically examined by various tax authorities. Beam is responsible for managing United States tax audits related to periods prior to July 29, 2011. Acushnet Company is obligated to support these audits and is responsible for managing all non-U.S. audits. The Company and certain subsidiaries have tax years that remain open and are subject to examination by tax authorities in the following major taxing jurisdictions: United States for years after July 29, 2011, Canada for years after 2013, Japan for years after 2012, Korea for years after 2016, and the United Kingdom for years after 2016. The Company files income tax returns on a combined, unitary, or stand-alone basis in multiple state and local jurisdictions, which generally have statute of limitations from three to four years. Various states and local income tax returns are currently in the process of examination. These examinations are unlikely to result in any significant changes to the amounts of unrecognized tax benefits on the consolidated balance sheet as of December 31, 2018 . The Company's income tax expense includes tax expense of $0.3 million , $0.2 million and $2.2 million for the years ended December 31, 2018 , 2017 and 2016 , respectively, related to the tax obligations indemnified by Beam. There is an offsetting amount included in other expense, net for the related adjustment to the Beam indemnification asset, resulting in no effect on net income. Income tax expense was as follows: Year ended December 31, (in thousands) 2018 2017 2016 Current expense (benefit) United States $ 1,795 $ (906 ) $ 3,702 Foreign 29,896 28,109 28,156 Current income tax expense 31,691 27,203 31,858 Deferred expense (benefit) United States 16,222 21,189 9,489 Foreign (681 ) 83 (1,640 ) Deferred income tax expense 15,541 21,272 7,849 Total income tax expense $ 47,232 $ 48,475 $ 39,707 The components of net deferred tax assets (liabilities) were as follows: December 31, (in thousands) 2018 2017 Deferred tax assets Compensation and benefits $ 14,036 $ 14,060 Share-based compensation 7,446 5,085 Pension and other postretirement benefits 22,285 30,564 Inventories 11,505 10,843 R&D capitalization 6,449 — Accounts receivable 1,101 2,016 Customer sales incentives 1,902 2,255 Transaction costs 1,580 1,804 Other reserves 3,987 3,255 Interest 771 562 Miscellaneous 1,871 1,224 Foreign exchange derivative instruments — 730 Net operating loss and other tax carryforwards 80,776 103,455 Gross deferred tax assets 153,709 175,853 Valuation allowance (15,542 ) (25,579 ) Total deferred tax assets 138,167 150,274 Deferred tax liabilities Property, plant and equipment (8,057 ) (11,325 ) Identifiable intangible assets (54,571 ) (47,876 ) Foreign exchange derivative instruments (1,176 ) — Miscellaneous (970 ) (954 ) Total deferred tax liabilities (64,774 ) (60,155 ) Net deferred tax asset $ 73,393 $ 90,119 Under U.S. tax law and regulations, certain changes in the ownership of the Company’s shares can limit the annual utilization of tax attributes (tax loss and tax credit carryforwards) that were generated prior to such ownership changes. The annual limitation could affect the realizability of the Company’s deferred tax assets recorded in the financial statement for its tax credit carryforwards because the carryforward periods have a finite duration. The 2016 initial public offering, and associated share transfers, resulted in significant changes in the composition of the ownership of the Company’s shares. Based on its analysis of the change of ownership tax rules in conjunction with the estimated amount and source of its future earnings and related tax profile, the Company believes its existing tax attributes will be utilized prior to their expiration. As of December 31, 2018 and 2017 , the Company had state net operating loss (“NOL”) carryforwards of $158.9 million and $192.0 million , respectively. These NOL carryforwards expire between 2019 and 2037 . As of December 31, 2018 and 2017 , the Company had foreign tax credit carryforwards of $58.4 million and $72.8 million , respectively. These foreign tax credits will begin to expire in 2022 . Changes in the valuation allowance for deferred tax assets were as follows: Year ended December 31, (in thousands) 2018 2017 2016 Valuation allowance at beginning of year $ 25,579 $ 21,726 $ 20,771 Increases (decreases) recorded to income tax provision (10,037 ) 3,853 955 Valuation allowance at end of year $ 15,542 $ 25,579 $ 21,726 The Company evaluates the realizability of its deferred tax assets based upon the weight of available positive and negative evidence. In assessing the realizability of these assets, the Company considered numerous factors including historical profitability, the character and estimated future taxable income, prudent and feasible tax planning strategies, and the industry in which it operates. The Company’s conclusion was primarily driven by cumulative income in the U.S. tax jurisdiction and projections of future income driven by the sustained profitability. The change in the valuation allowance is comprised of an $18.4 million release of its previously recorded valuation allowance against state deferred tax assets, partially offset by an increase of $0.4 million related to state tax attributes, and an increase of $8.0 million related to excess U.S. foreign tax credits arising from its Japan branch operations. During 2018, the Company early adopted ASU 2018-02 under the aggregate portfolio approach. ASU 2018-02 allows for reclassification of stranded tax effects on items resulting from the 2018 Tax Act from AOCI to retained earnings. Certain tax effects become stranded in AOCI when deferred tax balances originally recorded at the historical income tax rate are adjusted in income from continuing operations based on a lower newly enacted income tax rate. As a result of the adoption, we reclassified the stranded income tax effects resulting from the 2017 Tax Act, decreasing accumulated other comprehensive loss by $4.1 million with a corresponding increase to retained earnings. The reclassification was primarily comprised of amounts relating to available-for-sale securities, pension, postretirement benefit plan obligations and currency translation matters.

Temporary Equity Disclosure [Abstract]
Redeemable Convertible Preferred Stock	Redeemable Convertible Preferred Stock Prior to the initial public offering, the Company had outstanding 1,838,027 shares of $0.001 par value Series A preferred stock. Given that certain redemption features of the Series A preferred stock were not solely within the control of the Company, the Series A preferred stock was classified outside of stockholders' equity. All outstanding Series A preferred stock were converted into common stock in conjunction with the Company’s initial public offering (Note 1 ). Upon conversion, all accrued but unpaid dividends on the shares of the Series A preferred stock were paid to each holder of the shares of the Series A preferred stock. The Company declared and paid dividends to the holders of the Series A preferred stock of $17.3 million during the year ended December 31, 2016 . Shares of Series A preferred stock that were redeemed or converted were canceled and retired and cannot be reissued by the Company.

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company's shareholders. Common shareholders are entitled to receive dividends whenever funds are legally available and when declared by the Board of Directors, subject to the prior rights of holders of all classes of stock outstanding. On June 7, 2018, the Board of Directors authorized the Company to repurchase up to an aggregate of $20.0 million of its issued and outstanding common stock from time to time.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Incentive Plans	Equity Incentive Plans On January 22, 2016 , the Company’s Board of Directors adopted the Acushnet Holdings Corp. 2015 Omnibus Incentive Plan (“2015 Plan”) pursuant to which the Company may grant stock options, stock appreciation rights, restricted shares of common stock, restricted stock units ("RSUs"), performance stock units (“PSUs”) and other share-based and cash-based awards to members of the Board of Directors, officers, employees, consultants and advisors of the Company. The 2015 Plan is administered by the compensation committee (the “Administrator”). The Administrator has the authority to establish the terms and conditions of any award issued or granted under the 2015 Plan. As of December 31, 2018 , the only awards that have been granted under the 2015 Plan are RSUs and PSUs. On January 1, 2012, the Company's Board of Directors adopted the EAR plan in order to compensate certain key employees. During the first quarter of 2017 , the Company’s outstanding EAR liability was settled in full by a cash payment to the participants. Restricted Stock and Performance Stock Units Each share issued with respect to RSUs and PSUs granted under the 2015 Plan reduces the number of shares available for grant. RSUs and PSUs forfeited and shares withheld to satisfy tax withholding obligations increase the number of shares available for grant. All RSUs and PSUs granted under the 2015 Plan have DERs, which entitle holders of RSUs and PSUs to the same dividend value per share as holders of common stock and can be paid in either cash or common stock. DERs are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs and PSUs. DERs are paid when the underlying shares are delivered. As of December 31, 2018 , there were 7,523,536 remaining shares of common stock reserved for issuance under the 2015 Plan of which 5,671,859 remain available for future grants. RSUs vest, in accordance with the terms of the grant, over one to four years subject to the recipient’s continued service to the Company. PSUs cliff vest, subject to the employees continued employment with the Company, when achievement of the applicable performance metrics (as defined in the applicable award agreements) is deemed probable. A summary of the Company’s RSUs and PSUs as of December 31, 2018 and 2017 and changes during the years then ended is presented below: Number Weighted- Outstanding at December 31, 2016 2,459,166 $ 20.40 Granted 238,196 18.82 Vested (437,188 ) 20.33 Forfeited (199,320 ) 20.45 Outstanding at December 31, 2017 2,060,854 $ 20.23 Granted 473,724 23.49 Vested (1) (1,367,060 ) 20.36 Forfeited (285,686 ) 20.29 Outstanding at December 31, 2018 881,832 $ 21.75 (1) Included 63,490 shares of common stock related to RSUs and 900,226 shares of common stock related to PSUs that were not delivered as of December 31, 2018 . During 2018 , RSU vestings, including the impact of DERs issued in common stock, resulted in the issuance of 403,538 shares of common stock, of which 122,795 shares of common stock were withheld by the Company as payment by employees in lieu of cash to satisfy tax withholding obligations. The aggregate fair value of RSUs vesting during the year ended December 31, 2018 was $10.0 million . On December 31, 2018 , based upon the Company’s level of achievement of the applicable cumulative Adjusted EBITDA performance metrics, 900,226 of the outstanding PSUs cliff-vested, with the remaining outstanding PSUs forfeited. Each PSU reflected the right to receive between 0% and 200% of the target number of shares based on the actual three -year cumulative Adjusted EBITDA (as defined in the award agreements). The determination of the target value gave consideration to executive performance, potential future contributions and peer group analysis. As of December 31, 2018 , no shares of common stock have been delivered in connection with the PSU vesting. The aggregate fair value of PSUs vesting during the year ended December 31, 2018 was $19.0 million . Compensation expense recorded related to RSUs and PSUs in the consolidated statement of operations was as follows: Year ended December 31, (in thousands) 2018 2017 2016 RSU $ 12,353 $ 9,318 $ 8,361 PSU 6,210 5,967 6,133 The compensation expense recorded for the year ended December 31, 2018 related to the PSUs was based on the Company’s three -year cumulative Adjusted EBITDA as of December 31, 2018 . The remaining unrecognized compensation expense related to non-vested RSUs granted was $7.6 million as of December 31, 2018 and is expected to be recognized over the related weighted average period of 2.0 years. Equity Appreciation Rights Prior to settlement in 2017, the EAR awards were re-measured using the intrinsic value method at each reporting period based on a projection of the Company's future common stock equivalent value. The Company’s liability related to the EAR plan was $151.5 million as of December 31, 2016 and was recorded within accrued compensation and benefits on the consolidated balance sheet. The following table summarizes the Company's EAR activity since December 31, 2016 : (in thousands, except share and per share amounts) Number of Awards Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at December 31, 2016 7,614,000 $ 19.90 $ 151,511 Settled (7,614,000 ) (19.90 ) — Outstanding at December 31, 2017 — — For the year ended December 31, 2016 , the Company recorded compensation expense of $6.0 million related to outstanding EARs.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company’s operating segments are based on how the Chief Operating Decision Maker (“CODM”) makes decisions about assessing performance and allocating resources. The Company has four reportable segments that are organized on the basis of product categories. These segments include Titleist golf balls, Titleist golf clubs, Titleist golf gear and FootJoy golf wear. The CODM primarily evaluates performance using segment operating income. Segment operating income includes directly attributable expenses and certain shared costs of corporate administration that are allocated to the reportable segments, but excludes interest expense, net; the non-service cost component of net periodic benefit cost; EAR expense; losses on the fair value of common stock warrants; transaction fees and other non-operating gains and losses as the Company does not allocate these to the reportable segments. The CODM does not evaluate a measure of assets when assessing performance. Results shown for the years ended December 31, 2018 , 2017 and 2016 are not necessarily those which would be achieved if each segment was an unaffiliated business enterprise. There are no intersegment transactions. Information by reportable segment and a reconciliation to reported amounts are as follows: Year ended December 31, (in thousands) 2018 2017 2016 Net sales Titleist golf balls $ 523,967 $ 512,041 $ 513,899 Titleist golf clubs 445,341 397,987 430,966 Titleist golf gear 146,067 142,911 136,208 FootJoy golf wear 439,681 437,455 433,061 Other 78,665 69,864 58,141 Total net sales $ 1,633,721 $ 1,560,258 $ 1,572,275 Segment operating income Titleist golf balls $ 78,973 $ 78,419 $ 76,954 Titleist golf clubs 45,156 32,084 51,003 Titleist golf gear 15,430 16,803 12,212 FootJoy golf wear 17,974 27,038 19,305 Other 15,560 14,904 7,324 Total segment operating income 173,093 169,248 166,798 Reconciling items: Interest expense, net (18,402 ) (15,709 ) (49,908 ) Non-service cost component of net periodic benefit cost (4,416 ) (3,520 ) (1,665 ) EAR expense — — (6,047 ) Loss on fair value of common stock warrants — — (6,112 ) Transaction fees (599 ) (686 ) (16,817 ) Other 628 2,343 2,973 Total income before income tax $ 150,304 $ 151,676 $ 89,222 Depreciation and amortization expense by reportable segment are as follows: Year ended December 31, (in thousands) 2018 2017 2016 Depreciation and amortization Titleist golf balls $ 24,155 $ 25,545 $ 26,104 Titleist golf clubs 7,408 7,233 7,021 Titleist golf gear 1,531 1,425 1,250 FootJoy golf wear 6,731 6,058 5,759 Other 671 610 700 Total depreciation and amortization $ 40,496 $ 40,871 $ 40,834 Information as to the Company’s operations in different geographical areas is presented below.

Commitments and Contingencies	Commitments and Contingencies Purchase Obligations During the normal course of its business, the Company enters into agreements to purchase goods and services, including purchase commitments for production materials, finished goods inventory, capital expenditures and endorsement arrangements with professional golfers. The reported amounts exclude those liabilities included in accounts payable or accrued liabilities on the consolidated balance sheet as of December 31, 2018 . Purchase obligations by the Company as of December 31, 2018 were as follows: Payments Due by Period (in thousands) 2019 2020 2021 2022 2023 Thereafter Purchase obligations $ 151,463 $ 18,804 $ 6,113 $ 1,850 $ 1,391 $ 4,804 Lease Commitments The Company leases certain warehouses, distribution and office facilities, vehicles and office equipment under operating leases. Most lease arrangements provide the Company with the option to renew leases at defined terms. The future operating lease obligations would change if the Company were to exercise these options or if it were to enter into additional operating leases. The Company has an operating lease for certain vehicles that provides for a residual value guarantee. The lease has a noncancelable lease term of one year and may be renewed annually over the subsequent five years. The Company has the option to terminate the lease at the annual renewal date. Termination of the lease results in the sale of the vehicles and the determination of the residual value. The residual value is calculated by comparing the net proceeds of the vehicles sold to the depreciated value at the end of the renewal period. The Company is not responsible for any deficiency resulting from the net proceeds being less than 20% of the original cost in the first year and 20% of the depreciated value for all subsequent years. The Company believes that this guarantee will not have a significant impact on the consolidated financial statements. Future minimum rental payments under noncancelable operating leases as of December 31, 2018 were as follows: (in thousands) Year ending December 31, 2019 $ 13,119 2020 11,053 2021 7,984 2022 5,345 2023 3,133 Thereafter 13,852 Total minimum rental payments $ 54,486 Total rental expense for all operating leases amounted to $15.7 million , $16.3 million and $16.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Contingencies In connection with the Company’s acquisition of Acushnet Company, Beam indemnified the Company for certain tax related obligations that relate to periods during which Fortune Brands, Inc. owned Acushnet Company. As of December 31, 2018 and 2017 , the Company’s estimate of its receivable for these indemnifications was $8.9 million and $8.7 million , respectively, which was recorded in other noncurrent assets on the consolidated balance sheet. Litigation The Company and its subsidiaries are defendants in lawsuits associated with the normal conduct of their businesses and operations. It is not possible to predict the outcome of the pending actions, and, as with any litigation, it is possible that some of these actions could be decided unfavorably. Consequently, the Company is unable to estimate the ultimate aggregate amount of monetary loss, amounts covered by insurance or the financial impact that will result from such matters and has not recorded a liability related to potential losses.

During the fourth quarter of 2018, the Company revised the results for the fourth quarter of 2017 . The Company determined that in 2011 it did not record a required deferred income tax liability on the difference between the book and tax basis of intangible assets resulting from the 2011 acquisition of Acushnet Company. This deferred tax liability should have been remeasured during the fourth quarter of 2017 based upon the change in tax rates resulting from the 2017 Tax Act. The Company has corrected these errors as a revision to the previously issued financial statements and related footnotes. The correction of these errors resulted in a decrease in income tax expense of $6.6 million , an increase in net income of $6.6 million , an increase in basic net income per common share of $0.09 and an increase in diluted net income per common share of $0.08 for the quarter ended December 31, 2017 . See further discussion of the impact of these revisions included in Note 2 - Revision of Previously Issued Financial Statements.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying 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 the Company, its wholly- owned subsidiaries and less than wholly-owned subsidiaries, including 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.
Use of Estimates	Use of Estimates The preparation of the Company’s 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 consolidated financial statements. Actual results could differ from those estimates.
Variable Interest Entities	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 VIE have guaranteed the credit lines of the VIE, for which there were no outstanding borrowings as of December 31, 2018 and 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.
Noncontrolling Interests	Noncontrolling Interests The ownership interest held by owners other than the Company in less than wholly-owned subsidiaries are classified as noncontrolling interests. The value attributable to the noncontrolling interests is presented on the consolidated balance sheets within shareholders' equity, separately from the equity attributable to the Company. Net income (loss) and comprehensive income (loss) attributable to noncontrolling interests are presented separately on the consolidated statements of operations and consolidated statements of comprehensive income, respectively.
Cash and Restricted Cash	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.
Concentration of Credit Risk and of Significant Customers	Concentration of Credit Risk and of Significant Customers Financial instruments that potentially expose the Company to concentration of credit risk are cash and accounts receivable. Substantially all of the Company's cash deposits are maintained at large, creditworthy financial institutions. The Company's deposits, at times, may exceed federally insured limits. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. As part of its ongoing procedures, the Company monitors its concentration of deposits with various financial institutions in order to avoid any undue exposure. As of December 31, 2018 and 2017 , the Company had $28.6 million and $44.7 million , respectively, in banks located outside the United States. The risk with respect to the Company's accounts receivable is managed by the Company through its policy of monitoring the creditworthiness of its customers to which it grants credit terms in the normal course of business.
Inventories	Inventories Inventories are valued at the lower of cost and net realizable value. Cost is determined using the first-in, first-out inventory method. The inventory balance, which includes material, labor and manufacturing overhead costs, is recorded net of an allowance for obsolete or slow moving inventory. The Company's allowance for obsolete or slow moving inventory contains estimates regarding uncertainties. Such estimates are updated each reporting period and require the Company to make assumptions and to apply judgment regarding a number of factors, including market conditions, selling environment, historical results and current inventory trends.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation is recorded on a straight-line basis over the estimated useful lives of the assets. Gains or losses resulting from disposals are included in income from operations. Betterments and renewals, which improve and extend the life of an asset, are capitalized. Maintenance and repair costs are expensed as incurred. Estimated useful lives of property, plant and equipment asset categories were as follows: Buildings and improvements 15 - 40 years Machinery and equipment 3 - 10 years Furniture, fixtures and computer hardware 3 - 10 years Computer software 1 - 10 years Leasehold and tenant improvements are amortized over the shorter of the lease term or the estimated useful lives of the assets. Certain costs incurred in connection with the development of the Company's internal-use software are capitalized. Internal-use software development costs are primarily related to the Company's enterprise resource planning system. Costs incurred in the preliminary stages of development are expensed as incurred. Internal and external costs incurred in the application development phase, if direct and incremental, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing performed to ensure the product is ready for its intended use. Costs such as maintenance and training are expensed as incurred. The capitalized internal-use software costs are included in property, plant and equipment and once the software is placed into service are amortized over the estimated useful life which ranges from three to ten years .
Long-Lived Assets	Long-Lived Assets A long-lived asset (including amortizing intangible assets) or asset group is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, the Company compares the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of the asset or asset group. The cash flows are based on the best estimate of future cash flows derived from the most recent business projections. If the carrying value exceeds the sum of the undiscounted cash flows, an impairment loss is recognized based on the excess of the asset's or asset group's carrying value over its fair value. Fair value is determined based on discounted expected future cash flows on a market participant basis. Any impairment charge would be recognized within operating expenses as a selling, general and administrative expense. The Company continually evaluates whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets may warrant revision or that the remaining balance may not be recoverable. These factors may include a significant deterioration of operating results, changes in business plans, or changes in anticipated cash flows.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill and indefinite-lived intangible assets are not amortized but instead are measured for impairment at least annually, or more frequently when events or changes in circumstances indicate that the carrying amount of the asset may be impaired. Goodwill is assigned to reporting units for purposes of impairment testing. A reporting unit may be the same as an operating segment or one level below an operating segment. For purposes of assessing potential impairment, the Company compares the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is considered not impaired. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company records goodwill impairment in the amount of the excess of a reporting unit’s carrying value over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The fair value of the reporting units is determined using the income approach. The income approach uses a discounted cash flow analysis which involves applying appropriate discount rates to estimated future cash flows based on forecasts of sales, costs and capital requirements. Purchased intangible assets other than goodwill are amortized over their useful lives unless those lives are determined to be indefinite. Certain of the Company's trademarks have been assigned an indefinite life as the Company currently anticipates that these trademarks will contribute to its cash flows indefinitely. Indefinite-lived trademarks are reviewed for impairment annually and may be reviewed more frequently if indicators of impairment are present. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value. The Company measures the fair value of its trademarks using the relief-from-royalty method, which estimates the present value of royalty income that could be hypothetically earned by licensing the brand name to a third party over the remaining useful life. See Note 7 for additional information. The Company performs its annual impairment tests in the fourth quarter of each fiscal year.
Deferred Financing Costs	Deferred Financing Costs The Company defers costs directly associated with acquiring third-party financing. These deferred costs are amortized as interest expense over the term of the related indebtedness. Deferred financing costs associated with the revolving credit facilities are included in other current and noncurrent assets and deferred financing costs associated with all other indebtedness are netted against long-term debt and capital lease obligations on the consolidated balance sheet.
Fair Value Measurements	Fair Value Measurements Certain assets and liabilities are carried at fair value under U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The Company’s derivative instrument assets and liabilities are carried at fair value determined according to the fair value hierarchy described above (Note 11 and 12 ). The carrying value of accounts receivable, accounts payable and accrued expenses approximates fair value due to the short-term nature of these assets and liabilities. The Company adopted the fair value measurement disclosures for nonfinancial assets and liabilities, such as goodwill and indefinite-lived intangible assets. In some instances where a market price is available, but the instrument is in an inactive or over-the-counter market, the Company consistently applies the dealer (market maker) pricing estimate and uses a midpoint approach on bid and ask prices from financial institutions to determine the reasonableness of these estimates. Assets and liabilities subject to this fair value valuation approach are typically classified as Level 2.
Pension and Other Postretirement Benefit Plans	Pension and Other Postretirement Benefit Plans The Company provides U.S. and foreign defined benefit and defined contribution plans to certain eligible employees and postretirement benefits to certain retirees, including pensions, postretirement healthcare benefits and other postretirement benefits. Plan assets and obligations are measured using various actuarial assumptions, such as discount rates, rate of compensation increase, mortality rates, turnover rates and health care cost trend rates, as determined at each year end measurement date. The measurement of net periodic benefit cost is based on various actuarial assumptions, including discount rates, expected return on plan assets and rate of compensation increase, which are determined as of the prior year measurement date. The determination of the discount rate is generally based on an index created from a hypothetical bond portfolio consisting of high-quality fixed income securities with durations that match the timing of expected benefit payments. The expected return on plan assets is determined based on several factors, including adjusted historical returns, historical risk premiums for various asset classes and target asset allocations within the portfolio. Adjustments made to the historical returns are based on recent return experience in the equity and fixed income markets and the belief that deviations from historical returns are likely over the relevant investment horizon. Actual cost is also dependent on various other factors related to the employees covered by these plans. The effects of actuarial deviations from assumptions are generally accumulated and, if over a specified corridor, amortized over the remaining service period of the employees. The cost or benefit of plan changes, such as increasing or decreasing benefits for prior employee service (prior service cost), is deferred and included in expense on a straight-line basis over the average remaining service period of the related employees. The Company's actuarial assumptions are reviewed on an annual basis and modified when appropriate. To calculate the U.S. pension and postretirement benefit plan expense in 2018 and 2017, the Company applied the individual spot rates along the yield curve that correspond with the timing of each future cash outflow for the benefit payments in order to calculate interest cost and service cost. Prior to 2017, the service cost and interest cost components were determined using a single weighted-average discount rate. The change does not affect the measurement of the total benefit plan obligations, as the change in the service cost and interest cost offsets in the actuarial gains and losses recorded in other comprehensive income (loss). The Company changed to the new method to provide a more precise measure of service and interest cost by improving the correlation between the projected benefit cash flows and the discrete spot yield curve rates. The Company accounted for this change as a change in estimate prospectively beginning in 2017.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between consolidated financial statement carrying amounts and tax basis amounts at enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is recorded to reduce deferred income tax assets when it is more-likely-than-not that such assets will not be realized. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. The Company records liabilities for uncertain income tax positions based on the two step process. The first step is recognition, where an individual tax position is evaluated as to whether it has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, no tax benefit is recorded. For tax positions that have met the recognition threshold in the first step, the Company performs the second step of measuring the benefit to be recorded. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized on ultimate settlement. The actual benefits ultimately realized may differ from the estimates. In future periods, changes in facts, circumstances, and new information may require the Company to change the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recorded in income tax expense and liability in the period in which such changes occur. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes on the consolidated statements of income. Beam has indemnified certain tax obligations that relate to periods during which Fortune Brands, Inc. owned Acushnet Company (Note 23 ). These estimated tax obligations are recorded in accrued taxes and other noncurrent liabilities, and the related indemnification receivable is recorded in other noncurrent assets on the consolidated balance sheet. Any changes in the value of these specifically identified tax obligations are recorded in the period identified in income tax expense and the related change in the indemnification asset is recorded in other expense, net on the consolidated statement of operations. See Note 14 for additional information. On December 22, 2017, the U.S. enacted the 2017 Tax Act. The 2017 Tax Act contains a new law that subjects the Company to a tax on Global Intangible Low-Taxed Income (“GILTI”), beginning in 2018. GILTI is a tax on foreign income in excess of a deemed return on tangible assets of related foreign corporations. Companies subject to GILTI have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for temporary differences, including outside basis differences, expected to reverse as GILTI. The Company has elected to account for GILTI as a period cost.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes all costs to make products salable, such as inbound freight, purchasing and receiving costs, inspection costs and transfer costs. In addition, all depreciation expense associated with assets used to manufacture products and make them salable is included in cost of goods sold.
Product Warranty	Product Warranty The Company has defined warranties ranging from one to two years. Products covered by the defined warranty policies include all Titleist golf products, FootJoy golf shoes, and FootJoy golf outerwear. These product warranties generally obligate the Company to pay for the cost of replacement products, including the cost of shipping replacement products to its customers. The estimated cost of satisfying future warranty claims is accrued at the time the sale is recorded. In estimating future warranty obligations, the Company considers various factors, including its warranty policies and practices, the historical frequency of claims, and the cost to replace or repair products under warranty.
Advertising and Promotion	Advertising and Promotion Advertising and promotional costs are included in selling, general and administrative expense on the consolidated statement of operations and include product endorsement arrangements with members of the various professional golf tours, media placement and production costs (television, print and internet), tour support expenses and point-of-sale materials. Advertising production costs are expensed as incurred. Media placement costs are expensed in the month the advertising first appears. Product endorsement arrangements are expensed based upon the specific provisions of player contracts.
Selling	Selling Selling expenses including field sales, sales administration and shipping and handling costs are included in selling, general and administrative expense on the consolidated statement of operations.
Research and Development	Research and Development Research and development expenses include product development, product improvement, product engineering, and process improvement costs and are expensed as incurred.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions Assets and liabilities denominated in foreign currency are translated into U.S. dollars at the actual rates of exchange at the balance sheet date. Revenues and expenses are translated at the average rates of exchange for the reporting period. The related translation adjustments are recorded as a component of accumulated other comprehensive loss. Transactions denominated in a currency other than the functional currency are re-measured into functional currency with resulting transaction gains or losses recorded as selling, general and administrative expense on the consolidated statement of operations.
Derivative Financial Instruments	Derivative Financial Instruments All derivative instruments are recognized as either assets or liabilities on the consolidated balance sheet and are measured at fair value. If the derivative instrument is designated as a fair value hedge, the changes in the fair value of the derivative instruments and of the hedged item attributable to the hedged risk are recognized in earnings in the same period. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive loss and are recognized in the consolidated statement of operations when the hedged item affects earnings. Any portion of the change in fair value that is determined to be ineffective is immediately recognized in earnings. Cash flows from derivative financial instruments and the related hedged transactions are included in cash flows from operating activities. See Note 11 for additional information.
Share-based Compensation	Share-based Compensation The Company has a share-based compensation plan for board of directors, officers, employees, consultants and advisors of the Company. All awards granted under the plan are measured at fair value at the date of the grant. The Company issues share-based awards with service-based vesting conditions and performance-based vesting conditions. Awards with service-based vesting conditions are amortized as expense over the requisite service period of the award, which is generally the vesting period of the respective award. For awards with performance-based vesting conditions, the measurement of the expense is based on the Company’s level of achievement of performance metrics as defined in the applicable award agreements. The Company accounts for forfeitures in compensation expense when they occur.
Net Income per Common Share	Net Income per Common Share Net income per common share attributable to Acushnet Holdings Corp. is calculated under the treasury stock method. Prior to the conversion of the redeemable convertible preferred shares to common stock in connection with the Company’s initial public offering in 2016, the Company applied the two-class method to calculate its basic and diluted net income per common share attributable to Acushnet Holdings Corp., as its redeemable convertible preferred shares were participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. Net income per common share available to Acushnet Holdings Corp. was determined by allocating undistributed earnings between holders of common shares and redeemable convertible preferred shares, based on the participation rights of the preferred shares. Basic net income per common share attributable to Acushnet Holdings Corp. was computed by dividing the net income available to Acushnet Holdings Corp. by the basic weighted-average number of common shares outstanding during the period. Diluted net income per common share attributable to Acushnet Holdings Corp. was computed by dividing the net income available to Acushnet Holdings Corp. after giving effect to the diluted securities by the weighted-average number of dilutive shares outstanding during the period.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Adopted Accounting Standards Revenue from Contracts with Customers On January 1, 2018, the Company adopted 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 3 ). 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, net of tax to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (Note 14 ). 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 (Note 18 ). 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, net of tax 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 Postretirement 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 $3.5 million and $1.7 million from cost of goods sold and operating expenses to other expense, net on the consolidated statement of operations for the years ended December 31, 2017 and 2016 , respectively (Notes 13 and 19 ). The adoption of this standard also resulted in the restatement of the Company's segment operating income for the years ended December 31, 2017 and 2016 (Note 21 ) and unaudited quarterly financial data for the quarter ended December 31, 2017 (Note 24 ). Intangibles—Goodwill and Other — Simplifying the Test for Goodwill Impairment On October 31, 2018, the Company adopted 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. The adoption of this standard did not have an impact on the Company's assessment of goodwill impairment or its consolidated financial statements. 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 Intangibles —Goodwill and Other —Internal-Use Software In August 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-15, "Intangibles —Goodwill and Other —Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract" ("ASU 2018-15"). The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 is effective for fiscal years ending after December 15, 2019. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the consolidated financial statements. Defined Benefit Plans—Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued ASU 2018-14, "Compensation —Retirement Benefits —Defined Benefit Plans —General (Subtopic 715-20) —Disclosure Framework —Changes to the Disclosure Requirements for Defined Benefit Plans" ("ASU 2018-14"). The amendments in this update remove defined benefit plan disclosures that are no longer considered cost-beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of this standard should be applied to all periods presented. The adoption of this standard will not have a material impact on the consolidated financial statements. Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820) —Disclosure Framework —Changes to the Disclosure Requirements for Fair Value Measurement" ("ASU 2018-13"). The amendments in this update improve the effectiveness of fair value measurement disclosures. ASU 2018-13 is effective for fiscal years ending after December 15, 2019. Early adoption is permitted. The adoption of this standard should be applied to all periods presented. The adoption of this standard will not have a material impact on the consolidated financial statements. Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities In August 2017, the 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. 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. Subsequent to ASU 2016-02, the FASB issued related ASUs, including ASU 2018-11, "Leases (Topic 842): Targeted Improvements" , which provides an optional approach to initially apply the new lease guidance upon the adoption date, without adjusting the comparative periods presented. The Company adopted ASU 2016-02 on January 1, 2019, using the optional transition approach which allows for a cumulative effect adjustment in the period of adoption and will not restate prior periods. Although the Company is continuing to assess the potential impact this ASU will have on its consolidated balance sheet and related disclosures, it expects the adoption of this standard to result in the recognition of right-of-use assets and lease liabilities in the range of $40.0 million and $50.0 million . The Company does not expect a material impact to its consolidated statements of operations or cash flows.
