Basis of Presentation [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Standard Motor Products, Inc. and subsidiaries (referred to as the “Company,” “we,” “us,” or “our”) is engaged in the manufacture and distribution of replacement parts for motor vehicles in the automotive aftermarket industry with a complementary focus on heavy duty, industrial equipment and the original equipment service market. The accompanying unaudited financial information should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017. The unaudited consolidated financial statements include our accounts and all domestic and international companies in which we have more than a 50% equity ownership, except in instances where the minority shareholder maintains substantive participating rights, in which case we follow the equity method of accounting. Investments in unconsolidated affiliates are accounted for on the equity method, as we do not have a controlling financial interest but have the ability to exercise significant influence. All significant inter-company items have been eliminated. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for the interim periods are not necessarily indicative of the results of operations for the entire year. Reclassification Certain prior period amounts in the accompanying consolidated financial statements and related notes have been reclassified to conform to the 2018 presentation.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies The preparation of consolidated annual and quarterly financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. We have made a number of estimates and assumptions in the preparation of these consolidated financial statements. We can give no assurance that actual results will not differ from those estimates. Some of the more significant estimates include allowances for doubtful accounts, realizability of inventory, goodwill and other intangible assets, depreciation and amortization of long-lived assets, product liability, other postretirement benefits, asbestos, environmental and litigation matters, the valuation of deferred tax assets and sales return allowances. There have been no material changes to our critical accounting policies and estimates from the information provided in Revenue from Contracts with Customers, Recently Issued Accounting Pronouncements Standards that were adopted Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers Effective January 1, 2018, we adopted the requirements of ASU 2014-09, Revenue from Contracts with Customers The adoption of the new standard did not result in a material difference between the recognition of revenue under ASU 2014-09 and prior accounting standards. For the majority of our net sales, revenue continues to be recognized when products are shipped from our distribution facilities, or when received by our customers, depending upon the terms of the contract. Under the new revenue standard, (1) the return of cores from customers used in our manufacturing processes for air conditioning compressors, diesel injectors, and diesel pumps is estimated and recorded as unreturned customer inventories at the time of sale, and (2) overstock returns are recorded gross of expected recoveries. Adoption of the new standard resulted in the recording of unreturned customer inventories, and an increase in accrued core liabilities and accrued customer returns, with partially offsetting changes in net sales and cost of sales, and no material change to our net income on an ongoing basis. The cumulative effect of the changes made to our consolidated balance sheet as of January 1, 2018 for the adoption of ASU 2014-09 is as follows (in thousands): Balance at December 31, 2017 Adjustments Due to Adoption of ASU 2014-09 Balance at January 1, 2018 Balance Sheet Unreturned customer inventories $ — $ 19,950 $ 19,950 Accrued customer returns 35,916 6,670 42,586 Accrued core liability 11,899 14,469 26,368 Retained earnings 357,153 (1,189 ) 355,964 The adoption of ASU 2014-09 As Reported Balances Without Adoption of ASU 2014-09 Effect of Change Balance Sheet Unreturned customer inventories $ 18,674 $ — $ 18,674 Prepaid expenses and other current assets 12,672 12,810 (138 ) Accrued customer returns 43,031 35,817 7,214 Accrued core liability 23,751 11,631 12,120 Retained earnings 359,232 360,030 (798 ) Statement of Operations Net sales $ 261,826 $ 259,478 $ 2,348 Cost of sales 189,237 187,418 1,819 Earnings from continuing operations before taxes 11,644 11,115 529 Provision for income taxes 3,047 2,909 138 Net earnings 7,989 7,598 391 See Note 3 for further information regarding our adoption of ASU 2014-09. The following table provides a brief description of the impact of additional recently adopted accounting pronouncements on our financial statements: Standard Description Date of adoption Effects on the financial statements or other significant matters ASU 2016-15, Statement of Cash Flows This standard is intended to reduce diversity in practice and to provide guidance as to how certain cash receipts and cash payments are presented and classified in the statement of cash flows. January 1, 2018 The retrospective adoption of the new standard did not result in any changes in our reporting of cash receipts and cash payments in our consolidate statement of cash flows. ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard requires employers that present operating income in their consolidated statement of operations to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating expenses (together with other employee compensation costs). The other components of net benefit cost, including amortization of prior service cost/credit, and settlement and curtailment effects, are to be included in other non-operating income (expense). The new standard requires retrospective reclassification of the effects of the new standard on the statement of operations. January 1, 2018 The adoption of the new standard resulted in the reclassification of all components of net periodic pension cost and net periodic postretirement benefit cost, other than the service cost component, in our statement of operations from selling, general and administrated expenses, to other non-operating income (expense). We adopted the new standard retrospectively, and as such, all prior period amounts have been reclassified for comparative purposes. Standards that are not yet adopted as of March 31, 2018 The following table provides a brief description of the additional recent accounting pronouncements that could have an impact on our financial statements. Standard Description Date of adoption Effects on the financial statements or other significant matters ASU 2016-02, Leases This standard outlines the need to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). For income statement purposes, the FASB retained the dual model, requiring leases to be classified as either operating or financing. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. January 1, 2019, with early adoption permitted The new standard must be adopted utilizing a modified retrospective transition, and provides for certain expedients. The new standard will require that we recognize all of our leases, including our current operating leases, on the balance sheet. To date, we have taken an inventory of all of our operating leases, which consist primarily of real estate and auto leases, and are currently evaluating the appropriate discount rates to use in calculating the right to use asset. We will be continuously assessing the impact of the new standard and the impact on our systems and processes through January 1, 2019, our planned date of adoption. ASU 2017-04, Simplifying the Test for Goodwill Impairme nt This standard is intended to simplify the accounting for goodwill impairment. ASU 2017-04 removes Step 2 of the test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. January 1, 2020, with early adoption permitted The new standard should be applied prospectively. We will consider the new standard when performing our annual impairment test and evaluate when we will adopt the new standard.

Net Sales [Abstract]
Net Sales	Note 3. Net Sales Significant Accounting Policy We recognize revenues when our performance obligation has been satisfied and the control of products has been transferred to a customer which typically occurs upon shipment. Revenue is measured as the amount of consideration we expect to receive in exchange for the transfer of goods or providing services. Shipping and handling costs, as well as freight to customers, are included in distribution expenses as part of selling, general and administrative expenses. Revenue Recognition We derive our revenue primarily from sales of replacement parts for motor vehicles from both our Engine Management and Temperature Control Segments. The amount of consideration we receive and revenue we recognize depends on the marketing incentives, product warranty and overstock returns we offer to our customers. For certain of our sales of remanufactured products, we also charge our customers a deposit for the return of a used core component which we can use in our future remanufacturing activities. Such deposit is not recognized as revenue at the time of the sale but rather carried as a core liability. At the same time, we estimate the core expected to be returned from the customer and record the estimated return as unreturned customer inventory. The liability is extinguished when a core is actually returned to us, or at period end when we estimate and recognize revenue for the core deposits not expected to be returned. We estimate and record provisions for cash discounts, quantity rebates, sales returns and warranties in the period the sale is recorded, based upon our prior experience and current trends. Significant management judgments and estimates must be made and used in estimating sales returns and allowances relating to revenue recognized in any accounting period. Product Warranty and Overstock Returns Many of our products carry a warranty ranging from a 90-day limited warranty to a lifetime limited warranty, which generally covers defects in materials or workmanship and failure to meet industry published specifications and/or the result of installation error. In addition to warranty returns, we also permit our customers to return new, undamaged products to us within customer-specific limits (which are generally limited to a specified percentage of their annual purchases from us) in the event that they have overstocked their inventories. At the time products are sold, we accrue a liability for product warranties and overstock returns as a percentage of sales based upon estimates established using historical information on the nature, frequency and average cost of the claim and the probability of the customer return. At the same time, we record an estimate of anticipated customer returns as unreturned customer inventory. Revision to these estimates is made when necessary, based upon changes in these factors. We regularly study trends of such claims. Disaggregation of Net Sales We disaggregate our net sales from contracts with customers by geographic area, major product group, and major sales channels for each of our segments, as we believe it best depicts how the nature, amount, timing and uncertainty of our net sales are affected by economic factors. The following tables provide disaggregation of net sales information for the three months ended March 31, 2018 and 2017 (in thousands): Three months ended March 31, 2018 (a) Engine Management Temperature Control Other (c) Total Geographic Area: United States $ 174,584 $ 55,571 $ — $ 230,155 Canada 7,804 3,931 2,107 13,842 Mexico 8,222 212 — 8,434 Europe 3,480 164 — 3,644 Other foreign 5,398 353 — 5,751 Total $ 199,488 $ 60,231 $ 2,107 $ 261,826 Major Product Group: Ignition, emissions and fuel system parts $ 160,732 $ — $ 1,662 $ 162,394 Wire and cable 38,756 — 191 38,947 Compressors — 29,898 (56 ) 29,842 Other climate control parts — 30,333 310 30,643 Total $ 199,488 $ 60,231 $ 2,107 $ 261,826 Major Sales Channel: Aftermarket $ 169,310 $ 51,630 $ 2,107 $ 223,047 OE/OES 25,056 8,101 — 33,157 Export 5,122 500 — 5,622 Total $ 199,488 $ 60,231 $ 2,107 $ 261,826 Three months ended March 31, 2017 (a)(b) Engine Management Temperature Control Other (c) Total Geographic Area: United States $ 185,902 $ 65,039 $ — $ 250,941 Canada 9,767 4,357 774 14,898 Mexico 7,031 224 — 7,255 Europe 3,814 204 — 4,018 Other foreign 4,800 466 — 5,266 Total $ 211,314 $ 70,290 $ 774 $ 282,378 Major Product Group: Ignition, emissions and fuel system parts $ 165,153 $ — $ 723 $ 165,876 Wire and cable 46,161 — 227 46,388 Compressors — 37,922 (302 ) 37,620 Other climate control parts — 32,368 126 32,494 Total $ 211,314 $ 70,290 $ 774 $ 282,378 Major Sales Channel: Aftermarket $ 179,765 $ 61,799 $ 774 $ 242,338 OE/OES 26,504 7,989 — 34,493 Export 5,045 502 — 5,547 Total $ 211,314 $ 70,290 $ 774 $ 282,378 (a) Segment net sales include intersegment sales in our Engine Management and Temperature Control segments. (b) Amounts have not been restated and are reported under accounting standards in effect in the period presented as we adopted ASU 2014-09, Revenue from Contracts with Customers (c) Other consists of the elimination of intersegment sales from our Engine Management and Temperature Control segments as well as sales from our Canadian business unit that does not meet the criteria of a reportable operating segment. Intersegment compressor sales for the three months ended March 31, 2018 and 2017 exceeded third party sales from our Canadian business unit. Geographic Area We sell our line of products primarily in the United States, with additional sales in Canada, Mexico, Europe, Asia and Latin America. Sales are attributed to countries based upon the location of the customer. Our sales are substantially denominated in U.S. dollars. Major Product Group The Engine Management segment of the Company principally generates revenue from the sale of automotive engine replacement parts including ignition, emission and fuel system parts, and wire and cable parts. The Temperature Control segment of the Company principally generates revenue from the sale of automotive temperature control systems replacement parts including air conditioning compressors and other climate control parts. Major Sales Channel In the aftermarket channel, we sell our products to warehouse distributors and retailers. Our customers buy directly from us and sell directly to jobber stores, professional technicians and to “do-it-yourselfers” who perform automotive repairs on their personal vehicles. In the Original Equipment (“OE”) and Original Equipment Service (“OES”) channel, we sell our products to original equipment manufacturers who redistribute our products within their distribution network, independent dealerships and service dealer technicians. Lastly, in the Export channel, our domestic entities sell to customers outside the United States.

We determined, at that time, that due to a lack of a voting majority and other qualitative factors, we do not control the operations of the joint venture and accordingly, our investment in the joint venture was accounted for under the equity method of accounting. In March 2018, we acquired an additional 15% equity interest in the joint venture for RMB 26,475,583 (approximately $4.2 million), thereby increasing our equity interest in the joint venture to 65%. Payment for our additional 15% investment will be made in six cash installments, with $0.7 million paid in March 2018 and the balance paid on various dates through May 2018. Although we have increased our equity interest in the joint venture to 65%, the minority shareholder will maintain participating rights that will allow it to participate in certain significant financial and operating decisions that occur in the ordinary course of business. As a result of the existence of these substantive participating rights of the minority shareholder, we will continue to account for our investment in the joint venture under the equity method of accounting. 2017 Equity Investment Foshan FGD SMP Automotive Compressor Co., Ltd. In November 2017, we formed a 50/50 joint venture with Foshan Guangdong Automotive Air Conditioning Co., Ltd. (“FGD”), a China-based manufacturer of air conditioning compressors for the automotive aftermarket and the Chinese OE market. We acquired our 50% interest in the joint venture for approximately $12.5 million. Payment for our acquired interest in the joint venture was made in installments with approximately $6.8 million paid in 2017 and the balance of approximately $5.7 million paid in January 2018. We determined that due to a lack of a voting majority, and other qualitative factors, we do not control the operations of the joint venture and accordingly, our investment in the joint venture is accounted for under the equity method of accounting.

Revolving Credit Facility In October 2015, we entered into a Credit Agreement with JPMorgan Chase Bank, N.A., as agent, and a syndicate of lenders for a senior secured revolving credit facility with a line of credit of up to $250 million (with an additional $50 million accordion feature) and a maturity date in October 2020. The line of credit under the agreement also allows for a $10 million line of credit to Canada as part of the $250 million available for borrowing. Direct borrowings under the credit agreement bear interest at LIBOR plus a margin ranging from 1.25% to 1.75% based on our borrowing availability, or floating at the alternate base rate plus a margin ranging from 0.25% to 0.75% based on our borrowing availability, at our option. The credit agreement is guaranteed by certain of our subsidiaries and secured by certain of our assets. Borrowings under the credit agreement are secured by substantially all of our assets, including accounts receivable, inventory and certain fixed assets, and those of certain of our subsidiaries. Availability under the credit agreement is based on a formula of eligible accounts receivable, eligible inventory, eligible equipment and eligible fixed assets. After taking into account outstanding borrowings under the credit agreement, there was an additional $120.8 million available for us to borrow pursuant to the formula at March 31, 2018 December At March 31, 2018, the weighted average interest rate on our credit agreement was 3%, which consisted of $90 million in direct borrowings. At December At any time that our borrowing availability is less than the greater of either (a) $25 million, or 10% of the commitments if fixed assets are not included in the borrowing base, or (b) $31.25 million, or 12.5% of the commitments if fixed assets are included in the borrowing base, the terms of the credit agreement provide for, among other provisions, a financial covenant requiring us, on a consolidated basis, to maintain a fixed charge coverage ratio of 1:1 at the end of each fiscal quarter (rolling four quarters). As of March 31, Polish Overdraft Facility In December 2017, our Polish subsidiary, SMP Poland sp.z.o.o., entered into an overdraft facility with HSBC Bank Polska S.A. (“HSBC Poland”) for Zloty 30 million (approximately $8.8 million). The facility expires in December 2018. Borrowings under the overdraft facility will bear interest at a rate equal to WIBOR + 0.75% and are guaranteed by Standard Motor Products, Inc., the ultimate parent company. At March 31, 2018, borrowings under the overdraft facility were Zloty 19.8 million (approximately $5.8 million). Deferred Financing Costs We had deferred financing costs of $0.9 million and $1 million as of March 31, 2018 and December 31, 2017, respectively. Deferred financing costs are related to our revolving credit facility. Deferred financing costs as of March 31, 2018 are being amortized in the amounts of $0.3 million for the remainder of 2018, $0.3 million in 2019, and $0.3 million in 2020.

Stock-Based Compensation Plans [Abstract]
Stock-Based Compensation Plans	Note 11. Stock-Based Compensation Plans We account for our stock-based compensation plans in accordance with the provisions of FASB ASC 718, Stock Compensation Restricted and Performance Stock Grants As part of the 2016 Omnibus Incentive Plan, we currently grant shares of restricted stock to eligible employees and our independent directors and performance-based stock to eligible employees. Selected executives and other key personnel are granted performance awards whose vesting is contingent upon meeting various performance measures with a retention feature. Performance-based shares are subject to a three-year measuring period and the achievement of performance targets and, depending upon the achievement of such performance targets, they may become vested on the third anniversary of the date of grant. Each period we evaluate the probability of achieving the applicable targets, and we adjust our accrual accordingly. Restricted shares granted to employees become fully vested upon the third anniversary of the date of grant; and for selected key executives, certain additional restricted share grants vest 25% upon the attainment of age 60, 25% upon the attainment of age 63 and become fully vested upon the attainment of age 65. Restricted shares granted to directors become fully vested upon the first anniversary of the date of grant. Commencing with the 2015 grants, restricted and performance shares issued to certain key executives and directors are subject to a one or two year holding period upon the lapse of the three year vesting period. Forfeitures on restricted stock grants are estimated at 5% for employees and 0% for executives and directors, respectively, based on our evaluation of historical and expected future turnover. Our restricted and performance-based share activity was as follows for the three months ended March 31, 2018: Shares Weighted Average Grant Date Fair Value Per Share Balance at December 31, 2017 853,958 $ 33.25 Granted 129 41.18 Vested (2,200 ) 41.71 Forfeited (1,575 ) 41.44 Balance at March 31, 2018 850,312 $ 33.21 We recorded compensation expense related to restricted shares and performance-based shares of $1.9 million ($1.4 million, net of tax) and $1.8 million ($1.1 million, net of tax) for the three months ended March 31, 2018 and 2017, respectively. The unamortized compensation expense related to our restricted and performance-based shares was $14.7 million at March 31, 2018, and is expected to be recognized as they vest over a weighted average period of 4.5 years and 0.1 years for employees and directors, respectively.

Employee Benefits [Abstract]
Employee Benefits	Note 12. Employee Benefits We provided, and continue to provide, certain medical and dental care benefits to eligible retired U.S. and Canadian employees. Under the U.S. plan, for non-union employees, a Health Reimbursement Account (“HRA”) was established beginning January 1, 2009 for each qualified U.S. retiree. Annually, and through the year ended December 31, 2016, a fixed amount was credited into the HRA to cover both medical and dental costs for all current and future eligible retirees. Under the Canadian plan, retiree medical and dental benefits were funded using insurance contracts. Premiums under the insurance contracts were funded on a pay-as-you-go basis. The postretirement medical plans to substantially all eligible U.S. and Canadian employees terminated on December 31, 2016. For U.S. plan participants, balances in the HRA accounts upon termination of the plan at December 31, 2016 will remain available for use until December 31, 2018. Any remaining balance at December 31, 2018 will be forfeited. Postretirement medical and dental benefits to eligible employees will continue to be provided to the 39 former union employees in the U.S. The components of net periodic benefit cost for our postretirement benefit plans for the three months ended March 31, 2018 and 2017 were as follows (in thousands): Three Months Ended Postretirement benefits 2018 2017 (1) Service cost $ — $ — Interest cost 2 2 Amortization of prior service cost — — Actuarial net (gain) loss (9 ) (59 ) Net periodic benefit cost (credit) $ (7 ) $ (57 ) (1) Net periodic benefit cost (credit) has been reclassified from selling, general and administrative expenses to other non-operating income (expense), net on our consolidated statement of operations upon adoption of ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost We maintain a defined contribution Supplemental Executive Retirement Plan for key employees. Under the plan, these employees may elect to defer a portion of their compensation and, in addition, we may at our discretion make contributions to the plan on behalf of the employees. In March 2018, we made company contributions to the plan of $0.6 million related to calendar year 2017. We also have an Employee Stock Ownership Plan and Trust for employees who are not covered by a collective bargaining agreement. In connection therewith, we maintain an employee benefits trust to which we contribute shares of treasury stock. We are authorized to instruct the trustees to distribute such shares toward the satisfaction of our future obligations under the plan. The shares held in trust are not considered outstanding for purposes of calculating earnings per share until they are committed to be released. The trustees will vote the shares in accordance with their fiduciary duties. During the three months ended March 31, 2018, we contributed to the trust an additional 53,300 shares from our treasury and released 53,300 shares from the trust leaving 200 shares remaining in the trust as of March 31, 2018.

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 13. Fair Value Measurements The carrying value of our financial instruments consisting of cash and cash equivalents, deferred compensation, and short term borrowings approximate their fair value. In each instance, fair value is determined after considering Level 1 inputs under the three-level fair value hierarchy. For fair value purposes, the carrying value of cash and cash equivalents approximates fair value due to the short maturity of those investments. The fair value of the assets held by the deferred compensation plan are based on the quoted market prices of the underlying funds which are held in registered investment companies. The carrying value of our revolving credit facilities, classified as short term borrowings, equals fair market value because the interest rate reflects current market rates.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 16. Commitments and Contingencies Asbestos In 1986, we acquired a brake business, which we subsequently sold in March 1998 and which is accounted for as a discontinued operation. When we originally acquired this brake business, we assumed future liabilities relating to any alleged exposure to asbestos-containing products manufactured by the seller of the acquired brake business. In accordance with the related purchase agreement, we agreed to assume the liabilities for all new claims filed on or after September 2001. Our ultimate exposure will depend upon the number of claims filed against us on or after September 2001 and the amounts paid for indemnity and defense thereof. At March 31, 2018, approximately 1,545 cases were outstanding for which we may be responsible for any related liabilities. Since inception in September 2001 through March 31, 2018, the amounts paid for settled claims are approximately $24.4 million. In evaluating our potential asbestos-related liability, we have considered various factors including, among other things, an actuarial study of the asbestos related liabilities performed by an independent actuarial firm, our settlement amounts and whether there are any co-defendants, the jurisdiction in which lawsuits are filed, and the status and results of settlement discussions. As is our accounting policy, we consider the advice of actuarial consultants with experience in assessing asbestos-related liabilities to estimate our potential claim liability. The methodology used to project asbestos-related liabilities and costs in our actuarial study considered: (1) historical data available from publicly available studies; (2) an analysis of our recent claims history to estimate likely filing rates into the future; (3) an analysis of our currently pending claims; and (4) an analysis of our settlements to date in order to develop average settlement values. The most recent actuarial study was performed as of August 31, 2017. The updated study has estimated an undiscounted liability for settlement payments, excluding legal costs and any potential recovery from insurance carriers, ranging from $35.2 million to $54 million for the period through 2060. The change from the prior year study was a $4.2 million increase for the low end of the range and a $6.3 million increase for the high end of the range. The increase in the estimated undiscounted liability from the prior year study at both the low end and high end of the range reflects our actual experience over the prior twelve months, our historical data and certain assumptions with respect to events that may occur in the future. Based on the information contained in the actuarial study and all other available information considered by us, we have concluded that no amount within the range of settlement payments was more likely than any other and, therefore, in assessing our asbestos liability we compare the low end of the range to our recorded liability to determine if an adjustment is required. Based upon the results of the August 31, 2017 actuarial study, in September 2017 we increased our asbestos liability to $35.2 million, the low end of the range, and recorded an incremental pre-tax provision of $6 million in earnings (loss) from discontinued operations in the accompanying statement of operations. Future legal costs, which are expensed as incurred and reported in loss from discontinued operations in the accompanying statement of operations, are estimated, according to the updated study, to range from $44.3 million to $79.6 million for the period through 2060. We plan to perform an annual actuarial evaluation during the third quarter of each year for the foreseeable future. Given the uncertainties associated with projecting such matters into the future and other factors outside our control, we can give no assurance that additional provisions will not be required. We will continue to monitor the circumstances surrounding these potential liabilities in determining whether additional provisions may be necessary. At the present time, however, we do not believe that any additional provisions would be reasonably likely to have a material adverse effect on our liquidity or consolidated financial position. Other Litigation We are currently involved in various other legal claims and legal proceedings (some of which may involve substantial amounts), including claims related to commercial disputes, product liability, employment, and environmental. Although these legal claims and legal proceedings are subject to inherent uncertainties, based on our understanding and evaluation of the relevant facts and circumstances, we believe that the ultimate outcome of these matters will not, either individually or in the aggregate, have a material adverse effect on our . We may at any time determine that settling any of these matters is in our best interests, which settlement may include substantial payments. Warranties We generally warrant our products against certain manufacturing and other defects. These product warranties are provided for specific periods of time of the product depending on the nature of the product. As of March 31, 2018 and 2017, we have accrued $20.6 million and $25.6 million, respectively, for estimated product warranty claims included in accrued customer returns. The accrued product warranty costs are based primarily on historical experience of actual warranty claims. The following table provides the changes in our product warranties (in thousands): Three Months Ended 2018 2017 Balance, beginning of period $ 20,929 $ 24,072 Liabilities accrued for current year sales 21,242 25,730 Settlements of warranty claims (21,611 ) (24,193 ) Balance, end of period $ 20,560 $ 25,609

For the majority of our net sales, revenue continues to be recognized when products are shipped from our distribution facilities, or when received by our customers, depending upon the terms of the contract. Under the new revenue standard, (1) the return of cores from customers used in our manufacturing processes for air conditioning compressors, diesel injectors, and diesel pumps is estimated and recorded as unreturned customer inventories at the time of sale, and (2) overstock returns are recorded gross of expected recoveries. Adoption of the new standard resulted in the recording of unreturned customer inventories, and an increase in accrued core liabilities and accrued customer returns, with partially offsetting changes in net sales and cost of sales, and no material change to our net income on an ongoing basis. The cumulative effect of the changes made to our consolidated balance sheet as of January 1, 2018 for the adoption of ASU 2014-09 is as follows (in thousands): Balance at December 31, 2017 Adjustments Due to Adoption of ASU 2014-09 Balance at January 1, 2018 Balance Sheet Unreturned customer inventories $ — $ 19,950 $ 19,950 Accrued customer returns 35,916 6,670 42,586 Accrued core liability 11,899 14,469 26,368 Retained earnings 357,153 (1,189 ) 355,964 The adoption of ASU 2014-09 As Reported Balances Without Adoption of ASU 2014-09 Effect of Change Balance Sheet Unreturned customer inventories $ 18,674 $ — $ 18,674 Prepaid expenses and other current assets 12,672 12,810 (138 ) Accrued customer returns 43,031 35,817 7,214 Accrued core liability 23,751 11,631 12,120 Retained earnings 359,232 360,030 (798 ) Statement of Operations Net sales $ 261,826 $ 259,478 $ 2,348 Cost of sales 189,237 187,418 1,819 Earnings from continuing operations before taxes 11,644 11,115 529 Provision for income taxes 3,047 2,909 138 Net earnings 7,989 7,598 391 See Note 3 for further information regarding our adoption of ASU 2014-09. The following table provides a brief description of the impact of additional recently adopted accounting pronouncements on our financial statements: Standard Description Date of adoption Effects on the financial statements or other significant matters ASU 2016-15, Statement of Cash Flows This standard is intended to reduce diversity in practice and to provide guidance as to how certain cash receipts and cash payments are presented and classified in the statement of cash flows. January 1, 2018 The retrospective adoption of the new standard did not result in any changes in our reporting of cash receipts and cash payments in our consolidate statement of cash flows. ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost This standard requires employers that present operating income in their consolidated statement of operations to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating expenses (together with other employee compensation costs). The other components of net benefit cost, including amortization of prior service cost/credit, and settlement and curtailment effects, are to be included in other non-operating income (expense). The new standard requires retrospective reclassification of the effects of the new standard on the statement of operations. January 1, 2018 The adoption of the new standard resulted in the reclassification of all components of net periodic pension cost and net periodic postretirement benefit cost, other than the service cost component, in our statement of operations from selling, general and administrated expenses, to other non-operating income (expense). We adopted the new standard retrospectively, and as such, all prior period amounts have been reclassified for comparative purposes. Standards that are not yet adopted as of March 31, 2018 The following table provides a brief description of the additional recent accounting pronouncements that could have an impact on our financial statements. Standard Description Date of adoption Effects on the financial statements or other significant matters ASU 2016-02, Leases This standard outlines the need to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). For income statement purposes, the FASB retained the dual model, requiring leases to be classified as either operating or financing. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. January 1, 2019, with early adoption permitted The new standard must be adopted utilizing a modified retrospective transition, and provides for certain expedients. The new standard will require that we recognize all of our leases, including our current operating leases, on the balance sheet. To date, we have taken an inventory of all of our operating leases, which consist primarily of real estate and auto leases, and are currently evaluating the appropriate discount rates to use in calculating the right to use asset. We will be continuously assessing the impact of the new standard and the impact on our systems and processes through January 1, 2019, our planned date of adoption. ASU 2017-04, Simplifying the Test for Goodwill Impairme nt This standard is intended to simplify the accounting for goodwill impairment. ASU 2017-04 removes Step 2 of the test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. January 1, 2020, with early adoption permitted The new standard should be applied prospectively. We will consider the new standard when performing our annual impairment test and evaluate when we will adopt the new standard.
