Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Principles of Consolidation Standard Motor Products, Inc. and subsidiaries (referred to hereinafter in these notes to the consolidated financial statements as “we,” “us,” “our” or the “Company”) is engaged in the manufacture and distribution of replacement parts for motor vehicles in the automotive aftermarket industry with a complementary focus on the heavy duty, industrial equipment and original equipment service markets. The 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. Use of Estimates In conformity with generally accepted accounting principles, we have made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements. Some of the more significant estimates include allowances for doubtful accounts, cash discounts, valuation of inventory, valuation of long-lived assets, goodwill and other intangible assets, depreciation and amortization of long-lived assets, product liability exposures, asbestos, environmental and litigation matters, valuation of deferred tax assets, share based compensation and sales returns and other allowances. We can give no assurances that actual results will not differ from those estimates. Although we do not believe that there is a reasonable likelihood that there will be a material change in the future estimate or in the assumptions that we use in calculating the estimate, unforeseen changes in the industry, or business could materially impact the estimate and may have a material adverse effect on our business, financial condition and results of operations. Reclassification Certain prior period amounts in the accompanying consolidated financial statements and related notes have been reclassified to conform to the presentation. Cash and Cash Equivalents We consider all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Allowance for Doubtful Accounts and Cash Discounts We do not generally require collateral for our trade accounts receivable. Accounts receivable have been reduced by an allowance for amounts that may become uncollectible in the future. These allowances are established based on a combination of write-off history, aging analysis, and specific account evaluations. When a receivable balance is known to be uncollectible, it is written off against the allowance for doubtful accounts. Cash discounts are provided based on an overall average experience rate applied to qualifying accounts receivable balances. Inventories Inventories are valued at the lower of cost and net realizable value. Cost is determined on the -in -out basis. Where appropriate, standard cost systems are utilized for purposes of determining cost; the standards are adjusted as necessary to ensure they approximate actual costs. Estimates of lower of cost and net realizable value of inventory are determined by comparing the actual cost of the product to the estimated selling prices in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation of the inventory. We also evaluate inventories on a regular basis to identify inventory on hand that may be obsolete or in excess of current and future projected market demand. For inventory deemed to be obsolete, we provide a reserve on the full value of the inventory. Inventory that is in excess of current and projected use is reduced by an allowance to a level that approximates our estimate of future demand. Future projected demand requires management judgment and is based upon (a) our review of historical trends and (b) our estimate of projected customer specific buying patterns and trends in the industry and markets in which we do business. Using rolling month historical information, we estimate future demand on a continuous basis. As such, the historical volatility of such estimates has been minimal. We maintain provisions for inventory reserves of and as of December and respectively. We utilize cores (used parts) in our remanufacturing processes for air conditioning compressors, diesel injectors, and diesel pumps. The production of air conditioning compressors, diesel injectors, and diesel pumps involves the rebuilding of used cores, which we acquire either in outright purchases from used parts brokers, or from returns pursuant to an exchange program with customers. Under such exchange programs, at the time of sale of air conditioning compressors, diesel injectors, and diesel pumps, we estimate the core expected to be returned from the customer and record the estimated return as unreturned customer inventory. In addition, many of our customers can return inventory to us based upon customer warranty and overstock arrangements within customer specific limits. At the time products are sold, we accrue a liability for product warranties and overstock returns and record as unreturned customer inventory our estimate of anticipated customer returns. Estimates are based upon historical information on the nature, frequency and probability of the customer return. Unreturned core, warranty and overstock customer inventory is recorded at standard cost. Revision to these estimates is made when necessary, based upon changes in these factors. We regularly study trends of such claims. Property, Plant and Equipment Property, plant and equipment are recorded at historical cost and are depreciated using the straight-line method of depreciation over the estimated useful lives as follows: Estimated Life Buildings 25 to 33-1/2 Building improvements 10 to 25 years Machinery and equipment 5 to years Tools, dies and auxiliary equipment 3 to years Furniture and fixtures 3 to years Leasehold improvements are depreciated over the shorter of the estimated useful life or the term of the lease. Costs related to maintenance and repairs which do not prolong the assets useful lives are expensed as incurred. We assess our property, plant and equipment to be held and used for impairment when indicators are present that the carrying value may not be recoverable. Leases We determine if an arrangement is a lease at inception. For operating leases, we include and report operating lease right-of-use (“ROU”) assets, sundry payables and accrued expenses, and noncurrent operating lease liabilities on our consolidated balance sheet for leases with a term longer than months. Finance leases are reported on our consolidated balance sheets in property, plant and equipment, current portion of other debt, and long-term debt. Operating lease ROU assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the total lease payments over the lease term. Our ROU assets represent the right to use an underlying leased asset over the existing lease term, and the corresponding lease liabilities represent our obligation to make lease payments arising from the lease agreement. As most of our leases do not provide for an implicit rate, we use our secured incremental borrowing rate based on the information available when determining the present value of our lease payments. Our lease terms may include options to terminate, or extend, our lease when it is reasonably certain that we will execute the option. Lease agreements may contain lease and non-lease components, which are generally accounted for separately. Operating lease expense is recognized on a straight-line basis over the lease term. Valuation of Long-Lived and Intangible Assets and Goodwill At acquisition, we estimate and record the fair value of purchased intangible assets, which primarily consist of customer relationships, trademarks and trade names, patents and non-compete agreements. The fair values of these intangible assets are estimated based on our assessment. Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill and certain other intangible assets having indefinite lives are not amortized to earnings, but instead are subject to periodic testing for impairment. Intangible assets determined to have definite lives are amortized over their remaining useful lives. We assess the impairment of long-lived assets, identifiable intangibles assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. With respect to goodwill and identifiable intangible assets having indefinite lives, we test for impairment on an annual basis or in interim periods if an event occurs or circumstances change that may indicate the fair value is below its carrying amount. Factors we consider important, which could trigger an impairment review, include the following: (a) significant underperformance relative to expected historical or projected future operating results; (b) significant changes in the manner of our use of the acquired assets or the strategy for our overall business; and (c) significant negative industry or economic trends. We review the fair values using the discounted cash flows method and market multiples. When performing our evaluation of goodwill for impairment, if we conclude qualitatively that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then the -step impairment test is not required. If we are unable to reach this conclusion, then we would perform the -step impairment test. Initially, the fair value of the reporting unit is compared to its carrying amount. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit; we are required to perform a step, as this is an indication that the reporting unit goodwill may be impaired. In this step, we compare the implied fair value of the reporting unit goodwill with the carrying amount of the reporting unit goodwill and recognize a charge for impairment to the extent the carrying value exceeds the implied fair value. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to all of the assets (recognized and unrecognized) and liabilities of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. On January we will adopt Accounting Standards Update (“ASU”) - Simplifying the Test for Goodwill Impairment (“ASU - ”) . ASU - removes the step of the impairment test, which requires a hypothetical purchase price allocation to determine the implied fair value of the reporting unit goodwill. Instead, under ASU - goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU - will be applied prospectively. Identifiable intangible assets having indefinite lives are reviewed for impairment on an annual basis using a methodology similar with that used to evaluate goodwill. Intangible assets having definite lives and other long-lived assets are reviewed for impairment whenever events such as product discontinuance, plant closures, product dispositions or other changes in circumstances indicate that the carrying amount may not be recoverable. In reviewing intangible assets having definite lives and other long-lived assets for impairment, we compare the carrying value of such assets to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. When the estimated undiscounted future cash flows are less than their carrying amount, an impairment loss is recognized equal to the difference between the assets fair value and their carrying value. There are inherent assumptions and estimates used in developing future cash flows requiring our judgment in applying these assumptions and estimates to the analysis of identifiable intangibles and long-lived asset impairment including projecting revenues, interest rates, tax rates and the cost of capital. Many of the factors used in assessing fair value are outside our control and it is reasonably likely that assumptions and estimates will change in future periods. These changes can result in future impairments. In the event our planning assumptions were modified resulting in impairment to our assets, we would be required to include an expense in our statement of operations, which could materially impact our business, financial condition and results of operations. Foreign Currency Translation Assets and liabilities of our foreign operations are translated into U.S. dollars at year-end exchange rates. Income statement accounts are translated using the average exchange rates prevailing during the year. The resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) and remains there until the underlying foreign operation is liquidated or substantially disposed of. Foreign currency transaction gains or losses are recorded in the statement of operations under the caption “other non-operating income (expense), net.” Revenue Recognition We derive our revenue primarily from sales of replacement parts for motor vehicles from both our Engine Management and Temperature Control Segments. 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. 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 -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 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 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. Significant judgments and estimates must be made and used in connection with establishing the sales returns and other allowances in any accounting period. Revision to these estimates is made when necessary, based upon changes in these factors. We regularly study trends of such claims. New Customer Acquisition Costs New customer acquisition costs refer to arrangements pursuant to which we incur change-over costs to induce a new customer to switch from a competitor’s brand. In addition, change-over costs include the costs related to removing the new customer’s inventory and replacing it with our inventory commonly referred to as a stocklift. New customer acquisition costs are recorded as a reduction to revenue when incurred. Selling, General and Administration Expenses Selling, general and administration expenses include shipping costs and advertising, which are expensed as incurred. Shipping and handling charges, as well as freight to customers, are included in distribution expenses as part of selling, general and administration expenses. Deferred Financing Costs Deferred financing costs represent costs incurred in conjunction with our debt financing activities. Deferred financing costs related to our revolving credit facility are capitalized and amortized over the life of the related financing arrangement. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired and are recorded in the statement of operations under the caption other non-operating income (expense), net. Accounting for Income Taxes Income taxes are calculated using the asset and liability method. Deferred tax assets and liabilities are determined based on the estimated future tax effects of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities, as measured by the current enacted tax rates. We maintain valuation allowances when it is more likely than not that all or a portion of a deferred asset will not be realized. The valuation allowance is intended to provide for the uncertainty regarding the ultimate utilization of our U.S. foreign tax credit carryovers and foreign net operating loss carryovers. In determining whether a valuation allowance is warranted, we consider all positive and negative evidence and all sources of taxable income such as prior earnings history, expected future earnings, carryback and carryforward periods and tax strategies to estimate if sufficient future taxable income will be generated to realize the deferred tax asset. The assessment of the adequacy of our valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that actual results differ from these estimates, or we adjust these estimates in future periods for current trends or expected changes in our estimating assumptions, we may need to modify the level of valuation allowance which could materially impact our business, financial condition and results of operations. The valuation allowance of as of December is intended to provide for the uncertainty regarding the ultimate realization of our U.S. foreign tax credit carryovers and foreign net operating loss carryovers. Based on these considerations, we believe it is more likely than not that we will realize the benefit of the net deferred tax asset of as of December which is net of the remaining valuation allowance. Tax benefits are recognized for an uncertain tax position when, in management's judgment, it is more likely than not that the position will be sustained upon examination by a taxing authority. For a tax position that meets the more-likely-than-not recognition threshold, the tax benefit is measured as the largest amount that is judged to have a greater than likelihood of being realized upon ultimate settlement with a taxing authority. The liability associated with unrecognized tax benefits is adjusted periodically due to changing circumstances and when new information becomes available. Such adjustments are recognized entirely in the period in which they are identified. During the years ended December and we did not establish a liability for uncertain tax positions. Environmental Reserves We are subject to various U.S. Federal and state and local environmental laws and regulations and are involved in certain environmental remediation efforts. We estimate and accrue our liabilities resulting from such matters based upon a variety of factors including the assessments of environmental engineers and consultants who provide estimates of potential liabilities and remediation costs. Such estimates are not discounted to reflect the time value of money due to the uncertainty in estimating the timing of the expenditures, which may extend over several years. Potential recoveries from insurers or other parties of environmental remediation liabilities are recognized independently from the recorded liability, and any asset related to the recovery will be recognized only when the realization of the claim for recovery is deemed probable. Asbestos Litigation In evaluating our potential asbestos-related liability, we use an actuarial study that is prepared by a leading actuarial firm with expertise in assessing asbestos-related liabilities. We evaluate the estimate of the range of undiscounted liability to determine which amount to accrue. 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 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. Legal costs are expensed as incurred. Loss Contingencies We have loss contingencies, for such matters as legal claims and legal proceedings. Establishing loss reserves for these matters requires estimates, judgment of risk exposure and ultimate liability. We record provisions when the liability is considered probable and reasonably estimable. Significant judgment is required for both the determination of probability and the determination as to whether an exposure can be reasonably estimated. We maintain an ongoing monitoring and identification process to assess how the activities are progressing against the accrued estimated costs. As additional information becomes available, we reassess our potential liability related to these matters. Adjustments to the liabilities are recorded in the statement of operations in the period when additional information becomes available. Such revisions of the potential liabilities could have a material adverse effect on our business, financial condition or results of operations. Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash investments and accounts receivable. We place our cash investments with high quality financial institutions and limit the amount of credit exposure to any institution. Although we are directly affected by developments in the vehicle parts industry, management does not believe significant credit risk exists. With respect to accounts receivable, such receivables are primarily from warehouse distributors and major retailers in the automotive aftermarket industry located in the U.S. We perform ongoing credit evaluations of our customers’ financial conditions. Our largest individual customers accounted for approximately of our consolidated net sales in and approximately of our consolidated net sales in and During O’Reilly, Advance, NAPA, and AutoZone accounted for , , and of our consolidated net sales, respectively. Net sales from each of the customers were reported in both our Engine Management and Temperature Control Segments. The loss of or more of these customers or, a significant reduction in purchases of our products from any of them, could have a materially adverse impact on our business, financial condition and results of operations. Foreign Cash Balances Substantially all of the cash and cash equivalents, including foreign cash balances, at December 31, 2019 and 2018 were uninsured. Foreign cash balances at December 31, 2019 and 2018 were $8.5 million and $11.1 million , respectively. Recently Issued Accounting Pronouncements Standards that were adopted Leases Effective January we adopted ASU - Leases, (“ASU - ”) using the modified retrospective approach. The modified retrospective approach provides a method for recording existing leases at adoption. The most significant impact in adopting the new standard was the recognition of right-of-use (“ROU”) assets and lease liabilities on our consolidated balance sheet for operating leases, while the accounting for finance leases remained substantially unchanged. The adoption of the new standard did not materially impact our consolidated statements of operations or cash flows. In adopting ASU - we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward our historical lease identification and lease classifications. In addition, upon adoption, we evaluated all of our leases, and in particular our real estate leases, to determine the appropriate lease term. In evaluating our leases, we determined that the lease term for of our leases should be lengthened, as we concluded that it is reasonably certain that we will exercise the renewal option in the lease. The lease term for all of our other leases remained unchanged. Additionally, we elected to apply the provisions of ASU - Targeted Improvements , which allows us to initially apply the new lease requirements as of the effective date. Comparative financial information for the prior periods presented were not restated but instead are reported under the accounting standards in effect in those prior periods. Adoption of the new standard resulted in the following changes in our consolidated balance sheet as of January 1, 2019 (in thousand s): Balance at December 2018 Adjustments Due to Adoption of ASU - Balance at January 2019 Balance Sheet Operating lease right-of-use asset $ — $ 38,580 $ 38,580 Sundry payables and accrued expenses 31,033 7,232 38,265 Noncurrent operating lease liabilities — 31,348 31,348 See Note for further information regarding our adoption of ASU - Standards that are not yet adopted as of December The following table provides a brief description of recently issued accounting pronouncements that have not yet been adopted as of December and that could have an impact on our financial statements: Standard Description Date of adoption Effects on the financial statements or other significant matters ASU - Simplifying the Test for Goodwill Impairment This standard is intended to simplify the accounting for goodwill impairment. ASU - removes Step 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 with early adoption permitted We will adopt the new standard on January The new standard will be applied prospectively. We anticipate that the adoption of this standard will not materially impact the amount of goodwill impairment, if any, when performing our annual impairment test. ASU - Financial Instruments – Credit Losses This standard creates a single model to measure impairment on financial assets, which includes trade accounts receivable. An estimate of expected credit losses on trade accounts receivable over their contractual life will be required to be recorded at inception, based on historical information, current conditions, and reasonable and supportable forecasts. January with early adoption permitted We will adopt the new standard on January We anticipate that the adoption of this standard will not have a material impact on the manner in which we estimate our allowance for doubtful accounts on trade accounts receivable, or on our consolidated financial statements.

Business Acquisitions and Investments [Abstract]
Business Acquisitions and Investments	3. Business Acquisitions and Investments 2019 Business Acquisition and Investment Jiangsu Che Yijia New Energy Technology Co., Ltd. Equity Investment In August 2019, we acquired an approximate 29% minority interest in Jiangsu Che Yijia New Energy Technology Co., Ltd. (“CYJ”) for approximately $5.1 million. Our investment in CYJ was funded through borrowings under our revolving credit facility with JPMorgan Chase Bank, N.A. CYJ is a manufacturer of air conditioning compressors for electric vehicles and is located in China. Our minority interest in CYJ is accounted for using the equity method of accounting. Pollak Business of Stoneridge, Inc. Acquisition In April 2019, we acquired certain assets and liabilities of the Pollak business of Stoneridge, Inc. for approximately $40 million, subject to post-closing adjustments. In May 2019, the post-closing adjustments were finalized at $1.6 million, reducing the purchase price to $38.4 million. The acquisition was funded through borrowings under our revolving credit facility with JPMorgan Chase Bank, N.A. Stoneridge’s Pollak business had manufacturing and distribution facilities in Canton, Massachusetts, El Paso, Texas, and Juarez, Mexico, and distributed a range of engine management products including sensors, switches, and connectors. The acquisition, reported as part of our Engine Management Segment, enhanced our growth opportunities in the OE/OES, heavy duty and commercial vehicle markets and added to our existing expertise in aftermarket distribution, product management and service. We have not acquired any of the Pollak facilities or employees, and have relocated all production to our existing facilities. Revenues generated from the acquired business were approximately $45 million for the year ended December 31, 2018. The following table presents the allocation of the purchase price to the assets acquired and liabilities assumed, based on their fair values (in thousands): Purchase Price $ 38,427 Assets acquired and liabilities assumed: Inventory $ 3,331 Property, plant and equipment, net 45 Intangible assets 24,650 Goodwill 10,401 Net assets acquired $ 38,427 Intangible assets acquired of $24.7 million consist of customer relationships related to the acquired OE/OES business of $17.2 million that will be amortized on a straight-line basis over the estimated useful life of 10 years; customer relationships related to the acquired aftermarket business of $7.2 million that will be amortized on a straight-line basis over the estimated useful life of 15 years; a trademark of $0.2 million that will be amortized on a straight-line basis over the estimated useful life of 10 years; and a non-compete agreement of $0.1 million that will be amortized on a straight-line basis over the estimated useful life of 5 years. Goodwill of $10.4 million was allocated to the Engine Management Segment and is deductible for income tax purposes. The goodwill reflects relationships, business specific knowledge and the replacement cost of an assembled workforce associated with personal reputations, as well as the value of expected synergies. Revenues included in our consolidated statements of operations for the acquisition were $28.2 million from the date of acquisition through December 31, 2019. 2018 Increase in Equity Investment Foshan GWO YNG SMP Vehicle Climate Control & Cooling Products Co. Ltd. In April 2014, we formed a 50/50 joint venture with Gwo Yng Enterprise Co., Ltd. (“Gwo Yng”), a China-based manufacturer of air conditioner accumulators, filter driers, hose assemblies and switches for the automotive aftermarket and OEM/OES markets. We acquired our 50% interest in the joint venture for approximately $14 million. 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 approximately $4.2 million, thereby increasing our equity interest in the joint venture to 65%. The $4.2 million payment for our additional 15% investment was made in cash installments throughout 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.

Sale of Receivables [Abstract]
Sale of Receivables	6. Sale of Receivables We are party to several supply chain financing arrangements, in which we may sell certain of our customers’ trade accounts receivable to such customers’ financial institutions. We sell our undivided interests in certain of these receivables at our discretion when we determine that the cost of these arrangements is less than the cost of servicing our receivables with existing debt. Under the terms of the agreements, we retain no rights or interest, have no obligations with respect to the sold receivables, and do not service the receivables after the sale Pursuant to these agreements, we sold $719 million and $720 million of receivables for the years ended December 31, 2019 and 2018, respectively, which was reflected as a reduction of accounts receivable in the consolidated balance sheet at the time of sale. A charge in the amount of $22 million, $24.4 million and $22.6 million related to the sale of receivables is included in selling, general and administrative expenses in our consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017, respectively. To the extent that these arrangements are terminated, our financial condition, results of operations, cash flows and liquidity could be adversely affected by extended payment terms, delays or failures in collecting trade accounts receivables. The utility of the supply chain financing arrangements also depends upon the LIBOR rate, as it is a component of the discount rate applicable to each arrangement. If the LIBOR rate increases significantly, we may be negatively impacted as we may not be able to pass these added costs on to our customers, which could have a material and adverse effect upon our financial condition, results of operations and cash flows.

Goodwill and Other Intangible Assets [Abstract]
Goodwill and Other Intangible Assets	9. Goodwill and Other Intangible Assets Goodwill We assess the impairment of long ‑ When performing our evaluation of goodwill for impairment, if we conclude qualitatively that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then the -step impairment test is not required. If we are unable to reach this conclusion, then we would perform the -step impairment test. In the step, the fair value of the reporting unit is compared to its carrying amount. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit; we are required to perform a step, as this is an indication that the reporting unit goodwill may be impaired. In this step, we compare the implied fair value of the reporting unit goodwill with the carrying amount of the reporting unit goodwill and recognize a charge for impairment to the extent the carrying value exceeds the implied fair value. As of December we performed a qualitative assessment of the likelihood of a goodwill impairment for both the Engine Management and Temperature Control reporting units. Based upon our qualitative assessment, we determined that it was not more likely than not that the fair value of the each of the Engine Management and Temperature Control reporting units were less than their respective carrying amounts. As such, we concluded that the -step impairment test would not be required, and that there would be no required goodwill impairment charge as of December at each of the Engine Management and Temperature Control reporting units. We did not have a goodwill impairment charge as of December and we do not believe that future impairments are probable. Changes in the carrying values of goodwill by operating segment during the years ended December 31, 2019 and 2018 are as follows (in thousands): Engine Management Temperature Control Total Balance as of December 31, 2017: Goodwill $ 91,631 $ 14,270 $ 105,901 Accumulated impairment losses (38,488 ) — (38,488 ) $ 53,143 $ 14,270 $ 67,413 Activity in 2018 Foreign currency exchange rate change (92 ) — (92 ) Balance as of December 31, 2018: Goodwill 91,539 14,270 105,809 Accumulated impairment losses (38,488 ) — (38,488 ) $ 53,051 $ 14,270 $ 67,321 Activity in 2019 Acquisition of Pollak Business of Stoneridge, Inc. 10,401 — 10,401 Foreign currency exchange rate change 80 — 80 Balance as of December 31, 2019: Goodwill 102,020 14,270 116,290 Accumulated impairment losses (38,488 ) — (38,488 ) $ 63,532 $ 14,270 $ 77,802 Acquired Intangible Assets Acquired identifiable intangible assets as of December 31, 2019 and 2018 consist of: December 31, 2019 2018 (In thousands) Customer relationships $ 111,692 $ 87,195 Trademarks and trade names 6,980 6,800 Non-compete agreements 3,276 3,193 Patents 723 723 Supply agreements 800 800 Leaseholds 160 160 Total acquired intangible assets 123,631 98,871 Less accumulated amortization (1) (59,431 ) (51,391 ) Net acquired intangible assets $ 64,200 $ 47,480 (1) Applies to all intangible assets, except for related trademarks and trade names totaling $5.2 million, which have indefinite useful lives and, as such, are not being amortized.

Ltd 2,243 2,158 Total $ 38,858 $ 32,469 Investment in Jiangsu Che Yijia New Energy Technology Co., Ltd. In August we acquired an approximate minority interest in Jiangsu Che Yijia New Energy Technology Co., Ltd. (“CYJ”) for approximately . Our investment in CYJ was funded through borrowings under our revolving credit facility with JPMorgan Chase, N.A. CYJ is a manufacturer of air conditioning compressors for electric vehicles and is located in China. Our minority interest in CYJ is accounted for using the equity method of accounting. We did not make any purchases from CYJ from the date of acquisition through December Investment in 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 $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. During the years ended December 31, 2019 and 2018, we made purchases from FGD of approximately and Investment in Foshan GWOYNG SMP Vehicle Climate Control & Cooling Products Co. Ltd. In April 2014, we formed a 50/50 joint venture with Gwo Yng Enterprise Co., Ltd. (“Gwo Yng”), a China-based manufacturer of air conditioner accumulators, filter driers, hose assemblies and switches for the automotive aftermarket and OEM/OES markets. We acquired our 50% interest in the joint venture for $14 million. 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 approximately $4.2 million, thereby increasing our equity interest in the joint venture to 65%. The $4.2 million payment for our additional 15% investment was made in cash installments throughout 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. During the years ended December 31, 2019 and 2018, we made purchases from Gwo Yng of approximately $12.7 million and $14.9 million, respectively. Investment in Orange Electronic Co. Ltd. In January 2013, we acquired an approximate 25% minority interest in Orange Electronic Co., Ltd. (“Orange”) for $6.3 million. Orange is a manufacturer of tire pressure monitoring system sensors and is located in Taiwan. As of December 31, 2019, our minority interest in Orange of 19.4% is accounted for using the equity method of accounting as we have the ability to exercise significant influence. During each of the fourth quarters of 2018 and 2017, after a review of the recent financial performance and near term prospects for Orange, we determined that the decline in quoted market prices below the carrying amount of our investment in Orange was other than temporary and, as such, recognized a noncash impairment charge of approximately $1.7 million and $1.8 million, respectively, in each quarter. The impairment charge has been reported in our Engine Management Segment and is included in other non-operating income (expense), net in our consolidated statements of operations. Purchases from Orange during the years ended December 31, 2019 and 2018 were approximately $3.5 million and $4.9 million, respectively.

Maturities of long-term debt are not material for the year ended December 31, 2019 and beyond. Revolving Credit Facility In December 2018, we amended our Credit Agreement with JPMorgan Chase Bank, N.A., as agent, and a syndicate of lenders. The amended credit agreement provides 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 extends the maturity date to December 2023 Borrowings under the amended 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 amended credit agreement is based on a formula of eligible accounts receivable, eligible drafts presented to the banks under our supply chain financing arrangements ; while letters of credit outstanding under the credit agreement were $ million at both December 31, 2019 and 2018. At December 31, 2019, the weighted average interest rate on our amended credit agreement was 3.5%, which consisted of $40 million in direct borrowings at 2.3% and an alternative base rate loan of $12.5 million at 5%.

As of December 31, 2019, we were not subject to these covenants. The amended credit agreement permits us to pay cash dividends of $20 million and make stock repurchases of $20 million in any fiscal year subject to a minimum availability of $25 million. Provided specific conditions are met, the amended credit agreement also permits acquisitions, permissible debt financing, capital expenditures, and cash dividend payments and stock repurchases of greater than $20 million. Polish Overdraft Facility Our Polish subsidiary, SMP Poland sp. z.o.o., has entered into an overdraft facility with HSBC France (Spolka Akcyjna) Oddzial w Polsce, formerly HSBC Bank Polska S.A., for December 2020 Deferred Financing Costs We have deferred financing costs of approximately $0.9 million and $1.1 million as of December 31, 2019 and 2018, respectively. Deferred financing costs as of December 31, 2019 are related to our revolving credit facility. In connection with the amendment to our Credit Agreement with JPMorgan Chase Bank, N.A., as agent, entered into in December 2018, we incurred and capitalized approximately $0.5 million of deferred financing costs related to bank, legal, and other professional fees which are being amortized, along with the preexisting deferred financing costs, through 2023, the term of the amended agreement.

Stock-Based Compensation Plans [Abstract]
Stock-Based Compensation Plans	14. Stock-Based Compensation Plans Our stock-based compensation program is a broad-based program designed to attract and retain employees while also aligning employees’ interests with the interests of our shareholders. In addition, members of our Board of Directors participate in our stock-based compensation program in connection with their service on our board. In May 2016, our Board of Directors and Shareholders approved the 2016 Omnibus Incentive Plan. The 2016 Omnibus Incentive Plan supersedes the 2006 Omnibus Incentive Plan, which terminated in May 2016. The 2016 Omnibus Incentive Plan is the only remaining plan available to provide stock-based incentive compensation to our employees, directors and other eligible persons. Under the 2016 Omnibus Incentive Plan, which terminates in May 2026, we are authorized to issue, among other things, shares of restricted and performance-based stock to eligible employees and restricted stock to directors of up to 1,100,000 shares. Shares issued under the plan that are cancelled, forfeited or expire by their terms are eligible to be granted again under the 2016 Omnibus Incentive Plan. Awards previously granted under the 2006 Omnibus Incentive Plan are not affected by the plan’s termination, while shares not yet granted under the plan are not available for future issuance. We account for our stock-based compensation plans in accordance with the provisions of ASC 718, Stock Compensation Stock-based compensation expense under our existing plans was $ million ($ million, net of tax), $ million ($ million, net of tax), and $ million ($ million, net of tax) for the years ended December 31, 2019, 2018 and 2017, respectively. Restricted Stock and Performance Share Grants 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 Prior to the time a restricted share becomes fully vested or a performance share is issued, the awardees cannot transfer, pledge, hypothecate or encumber such shares. Prior to the time a restricted share is fully vested, the awardees have all other rights of a stockholder, including the right to vote (but not receive dividends during the vesting period). Prior to the time a performance share is issued, the awardees shall have no rights as a stockholder. All shares and rights are subject to forfeiture if certain employment conditions are not met. Under the 2016 Omnibus Incentive Plan, 1,100,000 shares are authorized to be issued. At December 31, 2019, under the plan, there were an aggregate of (a) 778,071 shares of restricted and performance-based stock grants issued, net of forfeitures, and (b) 321,929 shares of common stock available for future grants. For the year ended December 31, 2019, 204,650 restricted and performance-based shares were granted (148,400 restricted shares and 56,250 performance-based shares). In determining the grant date fair value, the stock price on the date of grant, as quoted on the New York Stock Exchange, was reduced by the present value of dividends expected to be paid on the shares issued and outstanding during the requisite service period, discounted at a risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the restriction or vesting period at the grant date. In addition, a further discount for the lack of marketability reduced the fair value of grants issued to certain key executives and directors subject to the one The fair value of the shares at the date of grant is amortized to expense ratably over the vesting period. Forfeitures on restricted stock grants are estimated at 5% for employees and 0% for executives and directors, respectively, based on evaluation of historical and expected future turnover. As related to restricted and performance stock shares, we recorded compensation expense of $6.5 million ($4.9 million, net of tax), $7.4 million ($5.5 million, net of tax) and $7.1 million ($3.2 million, net of tax), for the years ended December 31, 2019, 2018 and 2017, respectively. The unamortized compensation expense related to our restricted and performance-based shares was $15.9 million and $15.8 million at December 31, 2019 and 2018, respectively and is expected to be recognized over a weighted average period of 4.6 years and 0.3 years for employees and directors, respectively, as of December 31, 2019 and over a weighted average period of 4.3 years and 0.3 years for employees and directors, respectively, as of December 31, 2018. Our restricted and performance-based share activity was as follows for the years ended December 31, 2019 and 2018: Shares Weighted Average Grant Date Fair Value per Share Balance at December 31, 2017 853,958 $ 33.25 Granted 198,004 39.36 Vested (167,811 ) 39.90 Forfeited (1) (14,110 ) 42.28 Balance at December 31, 2018 870,041 $ 34.59 Granted 204,650 42.05 Vested (188,693 ) 38.08 Forfeited (1) (33,458 ) 43.32 Balance at December 31, 2019 852,540 $ 35.26 (1) Due to the lack of achievement of performance targets, performance-based shares forfeited in the years ended December 31, 2019 and 2018 were shares and shares, respectively.

Employee Benefits Defined Contribution Plans We maintain various defined contribution plans, which include profit sharing and provide retirement benefits for substantially all of our employees. Matching obligations, in connection with the plans which are funded in cash and typically contributed to the plans in March of the following year, are as follows (in thousands): U.S. Defined Contribution Year ended December 31, 2019 $ 9,080 2018 8,928 2017 9,153 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, contributions of $0.6 million were made related to calendar year 2017. In March 2019, contributions of $0.3 million were made related to calendar year 2018. We have recorded an obligation of $0.3 million for 2019. We also have an Employee Stock Ownership Plan and Trust (“ESOP”) 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 its fiduciary duties. During 2019, we contributed to the trust an additional 49,100 shares from our treasury and released 49,100 shares from the trust leaving 200 shares remaining in the trust as of December 31, 2019. The provision for expense in connection with the ESOP was approximately $2.5 million in 2019, $2.6 million in 2018 and $2.2 million in 2017. Defined Benefit Pension Plan We maintain a defined benefit unfunded Supplemental Executive Retirement Plan (“SERP”). The SERP, as amended, is a defined benefit plan pursuant to which we will pay supplemental pension benefits to certain key employees upon the attainment of a contractual participant’s payment date based upon the employees’ years of service and compensation. There was no benefit obligation outstanding related to the SERP as of December 31, 2019 and 2018. We recorded no expense related to the plan during the years ended December 31, 2019, 2018 and 2017.

As related to the U.S. non-union employees, annually and through the year ended December 31, 2016, a fixed amount was credited into a Health Reimbursement account (“HRA”) to cover both medical and dental costs for all current and future eligible retirees. Balances in the HRA accounts upon termination of the plan at December 31, 2016 remained available for use until December 31, 2018. Any remaining balance at December 31, 2018 was forfeited. Postretirement medical and dental benefits to the remaining eligible 16 former union employees in the U.S. will continue to be provided.

Fair Value Measurements [Abstract]
Fair Value Measurements	17. 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.

Income Taxes The income tax provision (benefit) consists of the following (in thousands): Year Ended December 31, 2019 2018 2017 Current: Domestic $ 14,632 $ 26,821 $ 30,742 Foreign 3,019 3,180 3,139 Total current 17,651 30,001 33,881 Deferred: Domestic 4,677 (10,132 ) 18,833 Foreign 417 108 98 Total deferred 5,094 (10,024 ) 18,931 Total income tax provision $ 22,745 $ 19,977 $ 52,812 In December 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Act”), which included a broad range of tax reform affecting businesses, including the reduction of the federal corporate tax rate from 35% to 21%, changes in the deductibility of certain business expenses, and the manner in which international operations are taxed in the U.S. In connection with the enactment of the Act, our income tax provision for the fourth quarter of 2017 included an increase of $17.5 million, reflecting an increase of $16.1 million for the remeasurement of our net deferred tax assets and an increase in tax of $1.4 million due to the deemed repatriation of earnings of our foreign subsidiaries. As related to the deemed repatriation of earnings of foreign subsidiaries, the Act includes a mandatory one-time tax on accumulated earnings of foreign subsidiaries. As a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued are now subject to U.S. tax. In accordance with the guidelines provided in the Act, as of December 31, 2017 we aggregated our estimated foreign earnings and profits, and utilized participating deductions and available foreign tax credits. The gross repatriation tax was $2.3 million, which was offset by $0.9 million of foreign tax credits for a net repatriation tax charge of $1.4 million. During 2018, we refined and updated our calculation of the gross repatriation tax to $2.7 million, which was paid to the U.S. Treasury. The difference in the refined and updated repatriation tax and what was previously recorded in the fourth quarter of 2017 was reflected in the 2018 tax provision. Notwithstanding the U.S. taxation of these amounts, we intend to continue to invest most or all of these earnings indefinitely outside of the U.S., and do not expect to incur any significant additional taxes related to such amounts. Reconciliations between taxes at the U.S. Federal income tax rate and taxes at our effective income tax rate on earnings from continuing operations before income taxes are as follows (in thousands): Year Ended December 31, 2019 2018 2017 U.S. Federal income tax rate of 21% in 2019 and 2018, and 35% in 2017 $ 19,277 $ 16,135 $ 33,755 Increase (decrease) in tax rate resulting from: State and local income taxes, net of federal income tax benefit 3,328 2,781 3,138 Income tax (tax benefits) attributable to foreign income 191 1,598 (149 ) Other non-deductible items, net (409 ) (559 ) (1,319 ) Impact of Tax Cuts and Jobs Act — — 17,515 Change in valuation allowance 358 22 (128 ) Provision for income taxes $ 22,745 $ 19,977 $ 52,812 The following is a summary of the components of the net deferred tax assets and liabilities recognized in the accompanying consolidated balance sheets (in thousands): December 31, 2019 2018 Deferred tax assets: Inventories $ 12,077 $ 12,798 Allowance for customer returns 11,969 16,836 Postretirement benefits 50 58 Allowance for doubtful accounts 1,262 1,371 Accrued salaries and benefits 9,826 9,147 Tax credit carryforwards 609 272 Accrued asbestos liabilities 13,132 11,872 Other 148 127 49,073 52,481 Valuation allowance (757 ) (399 ) Total deferred tax assets 48,316 52,082 Deferred tax liabilities: Depreciation 7,706 7,755 Other 3,338 1,993 Total deferred tax liabilities 11,044 9,748 Net deferred tax assets $ 37,272 $ 42,334 In assessing the realizability of the deferred tax assets, we consider whether it is more likely than not that some portion or the entire deferred tax asset will be realized. Ultimately, the realization of the deferred tax asset is dependent upon the generation of sufficient taxable income in those periods in which temporary differences become deductible and/or net operating loss carryforwards can be utilized. We consider the level of historical taxable income, scheduled reversal of temporary differences, carryback and carryforward periods, tax planning strategies and projected future taxable income in determining whether a valuation allowance is warranted. We also consider cumulative losses in recent years as well as the impact of one-time events in assessing our pre-tax earnings. Assumptions regarding future taxable income require significant judgment. Our assumptions are consistent with estimates and plans used to manage our business. The valuation allowance of $0.8 million as of December 31, 2019 is intended to provide for uncertainty regarding the ultimate realization of our U.S. foreign tax credit carryovers and foreign net operating loss carryovers. Based on these considerations, we believe it is more likely than not that we would realize the benefit of the net deferred tax asset of $37.3 million as of December 31, 2019, which is net of the remaining valuation allowance. At December 31, 2019, we have foreign tax credit carryforwards of approximately $0.6 million that will expire in varying amounts by 2028 In accordance with generally accepted accounting practices, we recognize in our financial statements only those tax positions that meet the more-likely-than-not recognition threshold. We establish tax reserves for uncertain tax positions that do not meet this threshold. During the years ended December 31, 2019, 2018 and 2017, we did t establish a liability for uncertain tax positions. We are subject to taxation in the U.S. and various state, local and foreign jurisdictions. As of December 31, 2019, the Company is no longer subject to U.S. Federal tax examinations for years before 2016. We remain subject to examination by state and local tax authorities for tax years 2015 through 2018. Foreign jurisdictions have statutes of limitations generally ranging from 2 to 6 years. Years still open to examination by foreign tax authorities in major jurisdictions include Canada (2015 onward), Hong Kong (2014 onward), Mexico (2015 onward) and Poland (2014 onward). We do not presently anticipate that our unrecognized tax benefits will significantly increase or decrease over the next 12 months; however, actual developments in this area could differ from those currently expected.

Earnings Per Share [Abstract]
Earnings Per Share	19. Earnings Per Share We present two calculations of earnings per common share. “Basic” earnings per common share equals net income divided by weighted average common shares outstanding during the period. “Diluted” earnings per common share equals net income divided by the sum of weighted average common shares outstanding during the period plus potentially dilutive common shares. Potentially dilutive common shares that are anti-dilutive are excluded from net earnings per common share. The following are reconciliations of the earnings available to common stockholders and the shares used in calculating basic and dilutive net earnings per common share (in thousands, except per share data): Year Ended December 31, 2019 2018 2017 Basic Net Earnings Per Common Share: Earnings from continuing operations $ 69,051 $ 56,854 $ 43,630 Loss from discontinued operations (11,134 ) (13,851 ) (5,654 ) Net earnings available to common stockholders $ 57,917 $ 43,003 $ 37,976 Weighted average common shares outstanding 22,378 22,456 22,726 Earnings from continuing operations per common share $ 3.09 $ 2.53 $ 1.92 Loss from discontinued operations per common share (0.50 ) (0.62 ) (0.25 ) Basic net earnings per common share $ 2.59 $ 1.91 $ 1.67 Diluted Net Earnings Per Common Share: Earnings from continuing operations $ 69,051 $ 56,854 $ 43,630 Loss from discontinued operations (11,134 ) (13,851 ) (5,654 ) Net earnings available to common stockholders $ 57,917 $ 43,003 $ 37,976 Weighted average common shares outstanding 22,378 22,456 22,726 Plus incremental shares from assumed conversions: Dilutive effect of restricted stock and performance-based stock 440 476 472 Weighted average common shares outstanding – Diluted 22,818 22,932 23,198 Earnings from continuing operations per common share $ 3.03 $ 2.48 $ 1.88 Loss from discontinued operations per common share (0.49 ) (0.60 ) (0.24 ) Diluted net earnings per common share $ 2.54 $ 1.88 $ 1.64 The shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or because they were excluded under the treasury method (in thousands): 2019 2018 2017 Restricted and performance shares 255 249 248

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 control, fuel and safety related system products, 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.

Commitments and Contingencies	22. Commitments and Contingencies Total rent expense for the three years ended December 31, 2019 was as follows (in thousands): Total Real Estate Other 2019 (1) $ 11,382 $ 7,909 $ 3,473 2018 12,605 9,272 3,333 2017 11,954 8,983 2,971 (1) In For our operating lease minimal rental payments that we are obligated to make, see Note 2, “Leases.” Warranties We generally warrant our products against certain manufacturing and other defects. These product warranties are provided for specific periods of time depending on the nature of the product. As of December 31, 2019 and 2018, we have accrued $22.4 million and $19.6 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. Warranty expense for each of the years 2019, 2018 and 2017 were $99.3 million, $85.9 million and $94.4 million, respectively. The following table provides the changes in our product warranties: December 31, 2019 2018 (In thousands) Balance, beginning of period $ 19,636 $ 20,929 Liabilities accrued for current year sales 99,304 85,850 Settlements of warranty claims (96,495 ) (87,143 ) Balance, end of period $ 22,445 $ 19,636 Letters of Credit At December 31, 2019, we had outstanding letters of credit with certain vendors aggregating approximately $3.1 million. These letters of credit are being maintained as security for reimbursements to insurance companies and as security to the landlord of our administrative offices in Long Island City, New York. The contract amount of the letters of credit is a reasonable estimate of their value as the value for each is fixed over the life of the commitment. Change of Control Arrangements We have a change in control arrangement with one key officer. In the event of a change of control (as defined in the agreement), the executive will receive severance payments and certain other benefits as provided in his agreement. Asbestos In 1986, we acquired a brake business, which we subsequently sold in March 1998 and which is accounted for as a discontinued operation in the accompanying statement of operations. 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 settlements, awards of asbestos-related damages, and defense of such claims. At December 31, 2019, approximately 1,550 cases were outstanding for which we may be responsible for any related liabilities. Since inception in September 2001 through December 31, 2019, the amounts paid for settled claims are approximately $30.9 million. We do not have insurance coverage for the indemnity and defense costs associated with the claims we face. 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 such claims. 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; and perform an actuarial evaluation in the quarter of each year and whenever events or changes in circumstances indicate that additional provisions may be necessary. The methodology used to project asbestos-related liabilities and costs in our actuarial study considered: historical data available from publicly available studies; an analysis of our recent claims history to estimate likely filing rates into the future; an analysis of our currently pending claims; and an analysis of our settlements to date in order to develop average settlement values. 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 and awards of asbestos-related damages 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. As related to our potential asbestos-related liability, in we were a defendant in an asbestos liability case in California, in which we were found liable for in compensatory damages. We are pursuing all rights of appeal of this case. During the quarter of our actuarial firm revised the results of its August study. Based upon the results of the revised actuarial study, in December we increased our asbestos liability to and recorded an incremental pre-tax provision of in earnings (loss) from discontinued operations. In accordance with our policy to perform an annual actuarial evaluation in the quarter of each year, an updated actuarial study was performed as of August The results of the August study included an estimate of our undiscounted liability for settlement payments and awards of asbestos-related damages, excluding legal costs and any potential recovery from insurance carriers, ranging from to for the period through The change from the revised prior year study, which was performed in the quarter of was a increase for the low end of the range and a increase for the high end of the range. The increase in the estimated undiscounted liability from the revised prior year study at both the low end and high end of the range reflects our actual experience, our historical data and certain assumptions with respect to events that may occur in the future. Based upon the results of the August actuarial study, we increased our asbestos liability to , the low end of the range, and recorded an incremental pre-tax provision of in earnings (loss) from discontinued operations in the accompanying statement of operations. Future legal costs, which are expensed as incurred and reported in earnings (loss) from discontinued operations in the accompanying statement of operations, are estimated, according to the updated study, to range from to for the period through We plan to perform an annual actuarial evaluation during the third quarter of each year for the foreseeable future and whenever events or changes in circumstances indicate that additional provisions may be necessary. 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 events and changes in circumstances surrounding these potential liabilities in determining whether to perform additional actuarial evaluations and 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.

Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation Standard Motor Products, Inc. and subsidiaries (referred to hereinafter in these notes to the consolidated financial statements as “we,” “us,” “our” or the “Company”) is engaged in the manufacture and distribution of replacement parts for motor vehicles in the automotive aftermarket industry with a complementary focus on the heavy duty, industrial equipment and original equipment service markets. The 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.
Use of Estimates	Use of Estimates In conformity with generally accepted accounting principles, we have made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements. Some of the more significant estimates include allowances for doubtful accounts, cash discounts, valuation of inventory, valuation of long-lived assets, goodwill and other intangible assets, depreciation and amortization of long-lived assets, product liability exposures, asbestos, environmental and litigation matters, valuation of deferred tax assets, share based compensation and sales returns and other allowances. We can give no assurances that actual results will not differ from those estimates. Although we do not believe that there is a reasonable likelihood that there will be a material change in the future estimate or in the assumptions that we use in calculating the estimate, unforeseen changes in the industry, or business could materially impact the estimate and may have a material adverse effect on our business, financial condition and results of operations.
Reclassification	Reclassification Certain prior period amounts in the accompanying consolidated financial statements and related notes have been reclassified to conform to the presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments purchased with a maturity of three months or less to be cash equivalents.
Allowance for Doubtful Accounts and Cash Discounts	Allowance for Doubtful Accounts and Cash Discounts We do not generally require collateral for our trade accounts receivable. Accounts receivable have been reduced by an allowance for amounts that may become uncollectible in the future. These allowances are established based on a combination of write-off history, aging analysis, and specific account evaluations. When a receivable balance is known to be uncollectible, it is written off against the allowance for doubtful accounts. Cash discounts are provided based on an overall average experience rate applied to qualifying accounts receivable balances.
Inventories	Inventories Inventories are valued at the lower of cost and net realizable value. Cost is determined on the -in -out basis. Where appropriate, standard cost systems are utilized for purposes of determining cost; the standards are adjusted as necessary to ensure they approximate actual costs. Estimates of lower of cost and net realizable value of inventory are determined by comparing the actual cost of the product to the estimated selling prices in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation of the inventory. We also evaluate inventories on a regular basis to identify inventory on hand that may be obsolete or in excess of current and future projected market demand. For inventory deemed to be obsolete, we provide a reserve on the full value of the inventory. Inventory that is in excess of current and projected use is reduced by an allowance to a level that approximates our estimate of future demand. Future projected demand requires management judgment and is based upon (a) our review of historical trends and (b) our estimate of projected customer specific buying patterns and trends in the industry and markets in which we do business. Using rolling month historical information, we estimate future demand on a continuous basis. As such, the historical volatility of such estimates has been minimal. We maintain provisions for inventory reserves of and as of December and respectively. We utilize cores (used parts) in our remanufacturing processes for air conditioning compressors, diesel injectors, and diesel pumps. The production of air conditioning compressors, diesel injectors, and diesel pumps involves the rebuilding of used cores, which we acquire either in outright purchases from used parts brokers, or from returns pursuant to an exchange program with customers. Under such exchange programs, at the time of sale of air conditioning compressors, diesel injectors, and diesel pumps, we estimate the core expected to be returned from the customer and record the estimated return as unreturned customer inventory. In addition, many of our customers can return inventory to us based upon customer warranty and overstock arrangements within customer specific limits. At the time products are sold, we accrue a liability for product warranties and overstock returns and record as unreturned customer inventory our estimate of anticipated customer returns. Estimates are based upon historical information on the nature, frequency and probability of the customer return. Unreturned core, warranty and overstock customer inventory is recorded at standard cost. Revision to these estimates is made when necessary, based upon changes in these factors. We regularly study trends of such claims.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at historical cost and are depreciated using the straight-line method of depreciation over the estimated useful lives as follows: Estimated Life Buildings 25 to 33-1/2 Building improvements 10 to 25 years Machinery and equipment 5 to years Tools, dies and auxiliary equipment 3 to years Furniture and fixtures 3 to years Leasehold improvements are depreciated over the shorter of the estimated useful life or the term of the lease. Costs related to maintenance and repairs which do not prolong the assets useful lives are expensed as incurred. We assess our property, plant and equipment to be held and used for impairment when indicators are present that the carrying value may not be recoverable.
Leases	Leases We determine if an arrangement is a lease at inception. For operating leases, we include and report operating lease right-of-use (“ROU”) assets, sundry payables and accrued expenses, and noncurrent operating lease liabilities on our consolidated balance sheet for leases with a term longer than months. Finance leases are reported on our consolidated balance sheets in property, plant and equipment, current portion of other debt, and long-term debt. Operating lease ROU assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the total lease payments over the lease term. Our ROU assets represent the right to use an underlying leased asset over the existing lease term, and the corresponding lease liabilities represent our obligation to make lease payments arising from the lease agreement. As most of our leases do not provide for an implicit rate, we use our secured incremental borrowing rate based on the information available when determining the present value of our lease payments. Our lease terms may include options to terminate, or extend, our lease when it is reasonably certain that we will execute the option. Lease agreements may contain lease and non-lease components, which are generally accounted for separately. Operating lease expense is recognized on a straight-line basis over the lease term.
Valuation of Long-Lived and Intangible Assets and Goodwill	Valuation of Long-Lived and Intangible Assets and Goodwill At acquisition, we estimate and record the fair value of purchased intangible assets, which primarily consist of customer relationships, trademarks and trade names, patents and non-compete agreements. The fair values of these intangible assets are estimated based on our assessment. Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill and certain other intangible assets having indefinite lives are not amortized to earnings, but instead are subject to periodic testing for impairment. Intangible assets determined to have definite lives are amortized over their remaining useful lives. We assess the impairment of long-lived assets, identifiable intangibles assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. With respect to goodwill and identifiable intangible assets having indefinite lives, we test for impairment on an annual basis or in interim periods if an event occurs or circumstances change that may indicate the fair value is below its carrying amount. Factors we consider important, which could trigger an impairment review, include the following: (a) significant underperformance relative to expected historical or projected future operating results; (b) significant changes in the manner of our use of the acquired assets or the strategy for our overall business; and (c) significant negative industry or economic trends. We review the fair values using the discounted cash flows method and market multiples. When performing our evaluation of goodwill for impairment, if we conclude qualitatively that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then the -step impairment test is not required. If we are unable to reach this conclusion, then we would perform the -step impairment test. Initially, the fair value of the reporting unit is compared to its carrying amount. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit; we are required to perform a step, as this is an indication that the reporting unit goodwill may be impaired. In this step, we compare the implied fair value of the reporting unit goodwill with the carrying amount of the reporting unit goodwill and recognize a charge for impairment to the extent the carrying value exceeds the implied fair value. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to all of the assets (recognized and unrecognized) and liabilities of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. On January we will adopt Accounting Standards Update (“ASU”) - Simplifying the Test for Goodwill Impairment (“ASU - ”) . ASU - removes the step of the impairment test, which requires a hypothetical purchase price allocation to determine the implied fair value of the reporting unit goodwill. Instead, under ASU - goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU - will be applied prospectively. Identifiable intangible assets having indefinite lives are reviewed for impairment on an annual basis using a methodology similar with that used to evaluate goodwill. Intangible assets having definite lives and other long-lived assets are reviewed for impairment whenever events such as product discontinuance, plant closures, product dispositions or other changes in circumstances indicate that the carrying amount may not be recoverable. In reviewing intangible assets having definite lives and other long-lived assets for impairment, we compare the carrying value of such assets to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. When the estimated undiscounted future cash flows are less than their carrying amount, an impairment loss is recognized equal to the difference between the assets fair value and their carrying value. There are inherent assumptions and estimates used in developing future cash flows requiring our judgment in applying these assumptions and estimates to the analysis of identifiable intangibles and long-lived asset impairment including projecting revenues, interest rates, tax rates and the cost of capital. Many of the factors used in assessing fair value are outside our control and it is reasonably likely that assumptions and estimates will change in future periods. These changes can result in future impairments. In the event our planning assumptions were modified resulting in impairment to our assets, we would be required to include an expense in our statement of operations, which could materially impact our business, financial condition and results of operations.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of our foreign operations are translated into U.S. dollars at year-end exchange rates. Income statement accounts are translated using the average exchange rates prevailing during the year. The resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) and remains there until the underlying foreign operation is liquidated or substantially disposed of. Foreign currency transaction gains or losses are recorded in the statement of operations under the caption “other non-operating income (expense), net.”
Revenue Recognition	Revenue Recognition We derive our revenue primarily from sales of replacement parts for motor vehicles from both our Engine Management and Temperature Control Segments. 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. 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	Product Warranty and Overstock Returns Many of our products carry a warranty ranging from a -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 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 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. Significant judgments and estimates must be made and used in connection with establishing the sales returns and other allowances in any accounting period. Revision to these estimates is made when necessary, based upon changes in these factors. We regularly study trends of such claims.
New Customer Acquisition Costs	New Customer Acquisition Costs New customer acquisition costs refer to arrangements pursuant to which we incur change-over costs to induce a new customer to switch from a competitor’s brand. In addition, change-over costs include the costs related to removing the new customer’s inventory and replacing it with our inventory commonly referred to as a stocklift. New customer acquisition costs are recorded as a reduction to revenue when incurred.
Selling, General and Administration Expenses	Selling, General and Administration Expenses Selling, general and administration expenses include shipping costs and advertising, which are expensed as incurred. Shipping and handling charges, as well as freight to customers, are included in distribution expenses as part of selling, general and administration expenses.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs represent costs incurred in conjunction with our debt financing activities. Deferred financing costs related to our revolving credit facility are capitalized and amortized over the life of the related financing arrangement. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired and are recorded in the statement of operations under the caption other non-operating income (expense), net.
Accounting for Income Taxes	Accounting for Income Taxes Income taxes are calculated using the asset and liability method. Deferred tax assets and liabilities are determined based on the estimated future tax effects of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities, as measured by the current enacted tax rates. We maintain valuation allowances when it is more likely than not that all or a portion of a deferred asset will not be realized. The valuation allowance is intended to provide for the uncertainty regarding the ultimate utilization of our U.S. foreign tax credit carryovers and foreign net operating loss carryovers. In determining whether a valuation allowance is warranted, we consider all positive and negative evidence and all sources of taxable income such as prior earnings history, expected future earnings, carryback and carryforward periods and tax strategies to estimate if sufficient future taxable income will be generated to realize the deferred tax asset. The assessment of the adequacy of our valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that actual results differ from these estimates, or we adjust these estimates in future periods for current trends or expected changes in our estimating assumptions, we may need to modify the level of valuation allowance which could materially impact our business, financial condition and results of operations. The valuation allowance of as of December is intended to provide for the uncertainty regarding the ultimate realization of our U.S. foreign tax credit carryovers and foreign net operating loss carryovers. Based on these considerations, we believe it is more likely than not that we will realize the benefit of the net deferred tax asset of as of December which is net of the remaining valuation allowance. Tax benefits are recognized for an uncertain tax position when, in management's judgment, it is more likely than not that the position will be sustained upon examination by a taxing authority. For a tax position that meets the more-likely-than-not recognition threshold, the tax benefit is measured as the largest amount that is judged to have a greater than likelihood of being realized upon ultimate settlement with a taxing authority. The liability associated with unrecognized tax benefits is adjusted periodically due to changing circumstances and when new information becomes available. Such adjustments are recognized entirely in the period in which they are identified. During the years ended December and we did not establish a liability for uncertain tax positions.
Environmental Reserves	Environmental Reserves We are subject to various U.S. Federal and state and local environmental laws and regulations and are involved in certain environmental remediation efforts. We estimate and accrue our liabilities resulting from such matters based upon a variety of factors including the assessments of environmental engineers and consultants who provide estimates of potential liabilities and remediation costs. Such estimates are not discounted to reflect the time value of money due to the uncertainty in estimating the timing of the expenditures, which may extend over several years. Potential recoveries from insurers or other parties of environmental remediation liabilities are recognized independently from the recorded liability, and any asset related to the recovery will be recognized only when the realization of the claim for recovery is deemed probable.
Asbestos Litigation	Asbestos Litigation In evaluating our potential asbestos-related liability, we use an actuarial study that is prepared by a leading actuarial firm with expertise in assessing asbestos-related liabilities. We evaluate the estimate of the range of undiscounted liability to determine which amount to accrue. 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 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. Legal costs are expensed as incurred.
Loss Contingencies	Loss Contingencies We have loss contingencies, for such matters as legal claims and legal proceedings. Establishing loss reserves for these matters requires estimates, judgment of risk exposure and ultimate liability. We record provisions when the liability is considered probable and reasonably estimable. Significant judgment is required for both the determination of probability and the determination as to whether an exposure can be reasonably estimated. We maintain an ongoing monitoring and identification process to assess how the activities are progressing against the accrued estimated costs. As additional information becomes available, we reassess our potential liability related to these matters. Adjustments to the liabilities are recorded in the statement of operations in the period when additional information becomes available. Such revisions of the potential liabilities could have a material adverse effect on our business, financial condition or results of operations.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash investments and accounts receivable. We place our cash investments with high quality financial institutions and limit the amount of credit exposure to any institution. Although we are directly affected by developments in the vehicle parts industry, management does not believe significant credit risk exists. With respect to accounts receivable, such receivables are primarily from warehouse distributors and major retailers in the automotive aftermarket industry located in the U.S. We perform ongoing credit evaluations of our customers’ financial conditions. Our largest individual customers accounted for approximately of our consolidated net sales in and approximately of our consolidated net sales in and During O’Reilly, Advance, NAPA, and AutoZone accounted for , , and of our consolidated net sales, respectively. Net sales from each of the customers were reported in both our Engine Management and Temperature Control Segments. The loss of or more of these customers or, a significant reduction in purchases of our products from any of them, could have a materially adverse impact on our business, financial condition and results of operations.
Foreign Cash Balances	Foreign Cash Balances Substantially all of the cash and cash equivalents, including foreign cash balances, at December 31, 2019 and 2018 were uninsured. Foreign cash balances at December 31, 2019 and 2018 were $8.5 million and $11.1 million , respectively.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Standards that were adopted Leases Effective January we adopted ASU - Leases, (“ASU - ”) using the modified retrospective approach. The modified retrospective approach provides a method for recording existing leases at adoption. The most significant impact in adopting the new standard was the recognition of right-of-use (“ROU”) assets and lease liabilities on our consolidated balance sheet for operating leases, while the accounting for finance leases remained substantially unchanged. The adoption of the new standard did not materially impact our consolidated statements of operations or cash flows. In adopting ASU - we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward our historical lease identification and lease classifications. In addition, upon adoption, we evaluated all of our leases, and in particular our real estate leases, to determine the appropriate lease term. In evaluating our leases, we determined that the lease term for of our leases should be lengthened, as we concluded that it is reasonably certain that we will exercise the renewal option in the lease. The lease term for all of our other leases remained unchanged. Additionally, we elected to apply the provisions of ASU - Targeted Improvements , which allows us to initially apply the new lease requirements as of the effective date. Comparative financial information for the prior periods presented were not restated but instead are reported under the accounting standards in effect in those prior periods. Adoption of the new standard resulted in the following changes in our consolidated balance sheet as of January 1, 2019 (in thousand s): Balance at December 2018 Adjustments Due to Adoption of ASU - Balance at January 2019 Balance Sheet Operating lease right-of-use asset $ — $ 38,580 $ 38,580 Sundry payables and accrued expenses 31,033 7,232 38,265 Noncurrent operating lease liabilities — 31,348 31,348 See Note for further information regarding our adoption of ASU - Standards that are not yet adopted as of December The following table provides a brief description of recently issued accounting pronouncements that have not yet been adopted as of December and that could have an impact on our financial statements: Standard Description Date of adoption Effects on the financial statements or other significant matters ASU - Simplifying the Test for Goodwill Impairment This standard is intended to simplify the accounting for goodwill impairment. ASU - removes Step 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 with early adoption permitted We will adopt the new standard on January The new standard will be applied prospectively. We anticipate that the adoption of this standard will not materially impact the amount of goodwill impairment, if any, when performing our annual impairment test. ASU - Financial Instruments – Credit Losses This standard creates a single model to measure impairment on financial assets, which includes trade accounts receivable. An estimate of expected credit losses on trade accounts receivable over their contractual life will be required to be recorded at inception, based on historical information, current conditions, and reasonable and supportable forecasts. January with early adoption permitted We will adopt the new standard on January We anticipate that the adoption of this standard will not have a material impact on the manner in which we estimate our allowance for doubtful accounts on trade accounts receivable, or on our consolidated financial statements.
