Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Consolidation and Basis of Presentation: Park-Ohio Industries, Inc. (“ParkOhio,” “we” or the “Company”) is a diversified international company providing world-class customers with a supply chain management outsourcing service, capital equipment used on their production lines, and manufactured components used to assemble their products. The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. The consolidated financial statements include the accounts of the Company and all of its majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company does not have off-balance sheet arrangements or financings with unconsolidated entities or other persons. The Company leases certain real properties owned by related parties as described in Note 10. Transactions with related parties are not material to the Company’s financial position, results of operations or cash flows. Accounting Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements. Actual results could differ from those estimates. Cash Equivalents: The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Accounts Receivable and Allowance for Doubtful Accounts: Accounts receivable are recorded at net realizable value. Accounts receivable are reduced by an allowance for amounts that may become uncollectable in the future. The allowance for doubtful accounts was $4.5 million and $4.0 million at December 31, 2017 and 2016, respectfully. The Company’s policy is to identify and reserve for specific collectability concerns based on customers’ financial condition and payment history, as well as a general reserve based on historical trends and other information. During 2017 and 2016 , we sold approximately $80.0 million and $81.6 million , respectively, of accounts receivable to mitigate accounts receivable concentration risk and to provide additional financing capacity. In compliance with ASC 860, “Transfers and Servicing”, sales of accounts receivable are reflected as a reduction of accounts receivable in the Consolidated Balance Sheets and the proceeds are included in cash flows from operating activities in the Consolidated Statements of Cash Flows. In 2017 and 2016 , an expense in the amount of $0.6 million and $0.5 million , respectively, related to the discount on sale of accounts receivable is recorded in the Consolidated Statements of Income. Inventories: Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or net realizable value. Major Classes of Inventories December 31, 2017 December 31, 2016 (In millions) Finished goods $ 171.3 $ 131.4 Work in process 43.9 43.4 Raw materials and supplies 67.6 65.8 Inventories, net $ 282.8 $ 240.6 Other inventory items Inventory reserves $ (29.8 ) $ (30.2 ) Consigned Inventory $ 9.8 $ 12.2 Property, Plant and Equipment: Property, plant and equipment is carried at cost. Additions and improvements that extend the lives of assets are capitalized and expenditures for repairs and maintenance are charged to operations as incurred. Depreciation and amortization of fixed assets, including capital leases, is computed principally by the straight-line method based on the estimated useful lives of the assets ranging from five to 40 years for buildings, and one to 20 years for machinery and equipment (with the majority in the range of three to ten years). The following table summarizes property, plant and equipment: December 31, December 31, (In millions) Property, plant and equipment: Land and land improvements $ 11.5 $ 11.3 Buildings 76.1 77.0 Machinery and equipment 348.6 316.1 Leased property under capital leases 24.1 20.4 Total property, plant and equipment 460.3 424.8 Less accumulated depreciation 280.8 255.2 Property, plant and equipment, net $ 179.5 $ 169.6 Information regarding depreciation expense of property, plant and equipment follows: Year Ended December 31, 2017 2016 2015 (In millions) Depreciation expense $ 24.9 $ 23.5 $ 21.5 Goodwill and Indefinite-Lived Assets: In accordance with Accounting Standards Codification (“ASC”) 350, “ Intangibles — Goodwill and Other ” (“ASC 350”), goodwill and indefinite life intangible assets are not amortized, but rather are tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be an indicator of impairment in accordance with ASC 350 . Goodwill is tested for impairment at the reporting unit level and is based on the net assets for each reporting unit, including goodwill and intangible assets, compared to the fair value. Our reporting units have been identified at the component level. The Company completed its annual goodwill and indefinite-lived intangibles impairment testing as of October 1 of each year, noting no impairment. The Company uses an income approach, utilizing a discounted cash flow model based on forecasted cash flows and weighted average cost of capital, and other valuation techniques to determine fair value. See Notes 4 and 5 of the consolidated financial statements for additional disclosure on goodwill and indefinite-lived intangibles. Impairment of Other Long-Lived Assets: Other long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Upon indications of impairment, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The asset group would be considered impaired when the estimated future net undiscounted cash flows generated by the asset group are less than its carrying value. Fair Values of Financial Instruments: Certain financial instruments are required to be recorded at fair value. The Company measures financial assets and liabilities at fair value in three levels of inputs. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and borrowings under the Credit Agreement (as defined in Note 6) approximate fair value at December 31, 2017 and December 31, 2016 because of the short-term nature of these instruments. The fair values of long-term debt and pension plan assets are disclosed in Note 6 and Note 11, respectively. The Company has not changed its valuation techniques for measuring fair value during 2017 , and there were no transfers between levels during the periods presented. Income Taxes: The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and the tax bases of assets and liabilities and are measured using the current enacted tax rates. In determining these amounts, management determined the probability of realizing deferred tax assets, taking into consideration factors including historical operating results, cumulative earnings and losses, expectations of future earnings, taxable income and the extended period of time over which the postretirement benefits will be paid and accordingly records valuation allowances if, based on the weight of available evidence it is more likely than not that some portion or all of our deferred tax assets will not be realized as required by ASC 740, “Income Taxes” (“ASC 740”). Share-Based Compensation: The Company follows the provisions of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their grant date fair values. Compensation expense for awards with service conditions only that are subject to graded vesting is recognized on a straight-line basis over the term of the vesting period. Compensation expense of performance-based awards is recognized as an expense over the vesting periods of the awards using the accelerated attribution method once performance is deemed probable. Park-Ohio Holdings Corp. (“Holdings”) grants share-based compensation awards to Industries' employees. In accordance with ASC 718, such costs are allocated to Industries. Under the provisions of Holdings’ 2015 Equity and Incentive Compensation Plan (“2015 Plan”), which is administered by the Compensation Committee of Holdings' Board of Directors, incentive stock options, non-statutory stock options, stock appreciation rights (“SARs”), restricted share units, performance shares or stock awards may be awarded to directors and all employees of the Company and its subsidiaries. The 2015 Plan replaces in its entirety the 1998 Long-Term Incentive Plan, as amended (“1998 Plan”), but shares that remained available under the 1998 Plan were added to the aggregate share limit under that 2015 Plan. Stock options will be exercisable in whole or in installments as may be determined provided that no options will be exercisable more than ten years from date of grant. The exercise price will be the fair value at the date of grant. The aggregate number of shares of Holdings' common stock that may be awarded under the 2015 Plan is 98,586 . Revenue Recognition: The Company recognizes revenue, other than from long-term contracts, when title is transferred to the customer, typically upon shipment. Revenue from long-term contracts is accounted for under the percentage of completion method, and recognized on the basis of the percentage each contract’s cost to date bears to the total estimated contract cost. We follow this method since reasonably reliable estimates of revenue and costs of a contract can be made. Revenue earned on contracts in process that are in excess of billings is classified as unbilled contract revenues in Other current assets in the Consolidated Balance Sheet and totaled $40.1 million and $35.6 million at December 31, 2017 and 2016, respectively. Billings in excess of revenues earned on contracts in process are classified in Other accrued expenses in the Consolidated Balance Sheet and totaled $23.0 million and $22.7 million at December 31, 2017 and 2016, respectively. Cost of Sales : Cost of sales is primarily comprised of direct materials and supplies consumed in the manufacture of product; manufacturing labor, depreciation expense and direct overhead expense; and shipping and handling costs. Concentration of Credit Risk: The Company sells its products to customers in diversified industries. The Company performs ongoing credit evaluations of its customers’ financial condition but does not require collateral to support customer receivables. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. As of December 31, 2017 , the Company had uncollateralized receivables with six customers in the automotive industry, each with several locations, aggregating $ 42.7 million , which represented approximately 18% of the Company’s trade accounts receivable. During 2017 , sales to these customers amounted to approximately $ 291.3 million , which represented approximately 21% of the Company’s net sales. Environmental: The Company expenses environmental costs related to existing conditions resulting from past or current operations and from which no current or future benefit is discernible. Costs that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. The Company records a liability when environmental assessments and/or remedial efforts are probable and can be reasonably estimated. The estimated liability of the Company is not reduced for possible recoveries from insurance carriers and is undiscounted. Foreign Currency Translation: The functional currency for a majority of subsidiaries outside the United States is the local currency. Financial statements for these subsidiaries are translated into U.S. dollars at year-end exchange rates for assets and liabilities and weighted-average exchange rates for revenues and expenses. The resulting translation adjustments are recorded in Accumulated other comprehensive income (loss) in shareholder's equity. Gains and losses resulting from foreign currency translations, including intercompany transactions that are not considered permanent investments, are included in the Consolidated Statements of Income. Warranties: The Company estimates the amount of warranty claims on sold products that may be incurred based on current and historical data. The actual warranty expense could differ from the estimates made by the Company based on product performance. The following table presents the changes in the Company’s product warranty liability: Year Ended December 31, 2017 2016 2015 (In millions) Balance at January 1, $ 7.1 $ 6.1 $ 6.9 Claims paid during the year (4.0 ) (3.7 ) (4.7 ) Warranty expense 4.7 2.0 4.0 Acquired warranty liabilities 0.1 2.8 — Other — (0.1 ) (0.1 ) Balance at December 31, $ 7.9 $ 7.1 $ 6.1 Accounting Pronouncements Adopted In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The ASU simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows. The Company adopted this ASU effective January 1, 2017. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies resulting from share-based compensation awards vesting and exercises be recognized as a discrete income tax adjustment in the income statement. Previously, these amounts were recognized in Additional paid-in capital. In 2017, the Company recognized income tax expense of $0.2 million for excess tax deficiencies upon vesting of awards. In addition, ASU 2016-09 requires excess tax benefits and shortfalls to be prospectively excluded from the assumed future proceeds in the calculation of diluted shares. ASU 2016-09 also requires that excess tax benefits from share-based compensation awards be reported as operating activities in the Consolidated Statements of Cash Flows. Previously, this activity was included in financing activities on the Consolidated Statements of Cash Flows. The Company has elected to apply this change on a prospective basis. This change has an immaterial impact on our Consolidated Statements of Cash Flows. Also, we elected to continue to estimate forfeitures rather than account for them as they occur. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill impairment." The amendments in the ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The ASU is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company early adopted this guidance for its October 1, 2017 impairment test. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, a comprehensive new revenue recognition standard that will supersede existing guidance under U.S. GAAP. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Our implementation efforts included the identification of revenue within the scope of the standard, the evaluation of revenue contracts under the guidance, and assessing the impacts of the new standard on our financial statements. The new standard is effective for the Company for the first quarter of 2018, and we will utilize the modified retrospective method of adoption. This method allows companies to record a one-time adjustment to beginning retained earnings as of January 1, 2018 for the cumulative effect that the standard will have on open contracts at the date of adoption. During our implementation, we identified certain contracts which will require over time recognition under the new standard, either as goods are manufactured or services are performed, rather than at the time of shipment or completion as we do under existing guidance. Upon adoption, we expect to accelerate approximately $13 million to $17 million of revenue, resulting in a cumulative-effect adjustment of approximately $2 million to $4 million to our 2018 beginning retained earnings. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The Board also is addressing measurement of credit losses on financial assets in a separate project. This ASU is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is not permitted. The new guidance will be applied prospectively and is expected to have an immaterial impact on the financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The amendment establishes a comprehensive new lease accounting model. The new standard: (a) clarifies the definition of a lease; (b) requires a dual approach to lease classification similar to current lease classifications; and (c) causes lessees to recognize leases on the balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease-term of more than twelve months. This ASU is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a modified retrospective transition for capital or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements, but it does not require transition accounting for leases that expire prior to the date of initial application. The Company is currently evaluating the impact of adopting this guidance. In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The Company will adopt this standard on the required date of January 1, 2018. The Company is currently evaluating the impact of adopting this guidance. No other recently issued ASUs are expected to have a material impact on our results of operations, financial condition or liquidity.

Segment Reporting [Abstract]
Segments	Segments The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. Supply Technologies provides our customers with Total Supply Management™ services for a broad range of high-volume, specialty production components. Assembly Components manufactures cast aluminum components, automotive and industrial rubber and thermoplastic products, gasoline direct injection systems, fuel filler and hydraulic assemblies for automotive, agricultural equipment, construction equipment, heavy-duty truck and marine equipment industries, and also provides value-added services such as design and engineering, machining and assembly. Engineered Products operates a diverse group of niche manufacturing businesses that design and manufacture a broad range of high quality products engineered for specific customer applications. For purposes of measuring business segment performance, the Company utilizes segment operating income, which is defined as revenues less expenses identifiable to the product lines within each segment.

Business Combinations [Abstract]
Acquisitions	Acquisitions On April 28, 2017, the Company acquired Aero-Missile Components Inc. (“AMC”). AMC, which is included in our Supply Technologies segment, is a supply chain management business providing high-quality specialty fasteners and other components to the defense and aerospace markets in the United States. On October 3, 2017, the Company completed the acquisition of Heads & All Threads Ltd. (“HAT”). HAT, which is included in our Supply Technologies segment, is a leading European supplier of supply chain management services specializing in developing vendor-managed inventory programs of fasteners, machined parts and other class C components to various industrial end markets. On December 29, 2017, the Company completed the acquisition of an injection molding business. The acquisition, which is included in our Assembly Components segment, is a manufacturer of precision-molded rubber components for several industrial markets. The results of operations of the 2017 acquisitions are included our consolidated results from their respective acquisition dates. Collectively, the 2017 acquisitions contributed $18.5 million of sales for the year ended December 31, 2017. The combined purchase price of the 2017 acquisitions was $39.7 million , net of cash acquired. The purchase price allocations for the 2017 acquisitions are preliminary as of December 31, 2017, subject to finalization of the Company’s determination of the value of the assets acquired and liabilities assumed, which is expected to be completed as soon as practicable but no later than twelve months after the respective acquisition dates. Goodwill of $8.4 million and intangibles of $2.0 million are recorded in the December 31, 2017 consolidated balance sheet related to the 2017 acquisitions. In December 2016, the Company acquired all the outstanding capital stock of GH Electrotermia S.A. (“GH”), headquartered in Valencia, Spain, for $23.4 million in cash (net of $6.3 million cash acquired), plus the assumption of $13.9 million in debt. The Company finalized its valuation of the assets acquired and liabilities assumed during 2017. The purchase agreement stipulated potential contingent consideration of up to $2.1 million based on achievement of earnings before interest, taxes, depreciation and amortization (“EBITDA”) targets for 2016 and 2017. The EBITDA targets were not achieved, and therefore no contingent consideration was paid to the seller.

Interest on the Notes is payable semi-annually in arrears on April 15 and October 15 of each year, and the Notes mature on April 15, 2027. The Notes are unsecured senior obligations of ParkOhio and are guaranteed on an unsecured senior basis by the 100% owned material domestic subsidiaries of ParkOhio. Proceeds from the Notes issuance were used to repay in full the previously-outstanding 8.125% Senior Notes due 2021 in the aggregate principal amount of $250.0 million , the term loan and a portion of the borrowings outstanding under the revolving credit facility. The Notes are general unsecured senior obligations of the Company and are fully and unconditionally guaranteed on a joint and several basis by all material 100% owned domestic subsidiaries of the Company. Provisions of the indenture governing the Senior Notes and the Credit Agreement contain restrictions on the Company’s ability to incur additional indebtedness, to create liens or other encumbrances, to make certain payments, investments, loans and guarantees and to sell or otherwise dispose of a substantial portion of assets or to merge or consolidate with an unaffiliated entity. At December 31, 2017, the Company was in compliance with all financial covenants of the Credit Agreement. On April 17, 2017, ParkOhio also entered into a seventh amended and restated credit agreement (the “Amended Credit Agreement”) with a group of banks to increase the revolving credit facility to $350.0 million and extend the maturity date of borrowings under the facility to April 17, 2022. Furthermore, ParkOhio has the option, pursuant to the Amended Credit Agreement, to increase the availability under the revolving credit facility by an aggregate incremental amount up to $100.0 million . As of December 31, 2017, $112.7 million was borrowed on the U.S. portion of the facility; $12.0 million of an available $25.0 million was borrowed on the European sub-limit portion of the facility; and the Company had approximately $194.2 million of unused borrowing capacity under the revolving credit facility. None of the available $35.0 million of the Canadian sub-limit has been borrowed as of December 31, 2017. In connection with the April 2017 repurchase of Senior Notes due 2021 and amendment of our credit agreement, we recorded an $11.0 million loss on extinguishment of debt, representing premiums paid on early extinguishment of $8.0 million , the write-off of unamortized prior debt issuance costs of $2.5 million , and related fees and expenses of $0.5 million . On December 21, 2016, the Company, through its subsidiary, IEGE Industrial Equipment Holding Company Limited, entered into a financing agreement with Banco Bilbao Vizcaya Argentaria, S.A. The financing agreement provides the Company a loan up to $27.0 million as of December 31, 2017, as well as a revolving credit facility for up to $12.1 million to fund working capital and general corporate needs. The full $27.0 million loan is outstanding as of December 31, 2017. No amounts have been drawn on the revolving credit facility as of December 31, 2017. On October 21, 2015, the Company, through its subsidiary, Southwest Steel Processing LLC, entered into a financing agreement with the Arkansas Development Finance Authority.

The Tax Act reduces the US federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate to be included in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Tax Act; however, in certain cases, as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. For the items for which we were able to determine a reasonable estimate, we recognized a net provisional amount of $3.3 million , which is included as a component of income tax expense. In all cases, we will continue to make and refine our calculations as additional analysis is completed. In addition, our estimates may also be affected as we gain a more thorough understanding of the tax law. Provisional amounts Deferred tax assets and liabilities: We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the remeasurement of our deferred tax balance was a tax benefit of $10.9 million . The one-time transition tax is based on our total post-1986 earnings and profits (E&P) that we previously deferred from US income taxes. We recorded a provisional amount for our one-time transition tax liability for each of our foreign subsidiaries, resulting in an increase in income tax expense of $14.2 million . We have not yet completed our calculation of the total post-1986 E&P for these foreign subsidiaries. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalize the amounts held in cash or other specified assets. A reconciliation of income tax expense computed by applying the statutory federal income tax rate to income before income taxes as recorded is as follows: Year Ended December 31, 2017 2016 2015 (In millions) Tax at U.S. statutory rate $ 16.9 $ 14.7 $ 24.7 Effect of state income taxes, net 0.7 0.2 0.6 Effect of foreign operations (5.2 ) (2.1 ) (1.6 ) Valuation allowance 5.3 0.5 (0.7 ) Uncertain tax positions (2.0 ) (4.0 ) 0.1 Non-deductible items 0.5 0.6 0.5 Non-deductible compensation 0.4 0.8 1.2 Manufacturer's deduction (0.8 ) (0.5 ) (1.1 ) Net impact of U.S. Tax Act 3.3 — — Other, net (1.4 ) (1.0 ) (2.2 ) Total $ 17.7 $ 9.2 $ 21.5 Significant components of the Company’s net deferred income tax assets and liabilities are as follows: Year Ended December 31, 2017 2016 (In millions) Deferred income tax assets: Postretirement benefit obligation $ 2.0 $ 3.6 Inventory 9.9 13.7 Net operating loss and credit carryforwards 16.1 10.8 Warranty reserve 0.4 2.1 Accrued litigation 0.1 2.8 Compensation 4.2 4.1 Other 4.9 9.8 Total deferred income tax assets 37.6 46.9 Deferred income tax liabilities: Depreciation and amortization 10.4 16.0 Pension 16.3 22.1 Intangible assets 16.6 23.3 Other 3.3 5.2 Total deferred income tax liabilities 46.6 66.6 Net deferred income tax liabilities prior to valuation allowances (9.0 ) (19.7 ) Valuation allowances (11.6 ) (5.3 ) Net deferred income tax liability $ (20.6 ) $ (25.0 ) At December 31, 2017 , the Company has U.S., state and foreign net operating loss carryforwards and U.S. foreign tax credit carryforwards for income tax purposes. The foreign net operating loss carryforward is $32.4 million , of which $7.9 million expires between 2018 and 2037 and the remainder has no expiration date. The Company has a tax benefit from a state net operating loss carryforward of $2.1 million that expires between 2018 and 2037 . The Company also has a tax benefit from a non-consolidated U.S. net operating loss carryforward of $1.1 million that expires between 2035 and 2036. The foreign tax credit carryforward is $3.1 million and expires in 2027. As of December 31, 2017 and 2016 , the Company was not in a cumulative three -year loss position and it was determined that it was more likely than not that its U.S. deferred tax assets will be realized. During the years ended December 31, 2017 and 2016 , the Company recorded valuation allowances of $6.3 million and $4.5 million , respectively, against certain foreign net deferred tax assets and the U.S. foreign tax credits. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including reversals of deferred tax liabilities). The Company reviews all valuation allowances related to deferred tax assets and will reverse these valuation allowances, partially or totally, when appropriate under ASC 740. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: 2017 2016 2015 (In millions) Unrecognized Tax Benefit — January 1, $ 2.9 $ 6.3 $ 6.5 Gross Increases to Tax Positions Related to Current Year 0.1 — — Gross Increases to Tax Positions Related to Prior Years 0.6 0.3 0.3 Gross Decreases to Tax Positions Related to Prior Years — — (0.1 ) Gross Decreases Related to Settlements with Taxing Authorities (0.4 ) — — Expiration of Statute of Limitations (1.9 ) (3.7 ) (0.4 ) Other (0.1 ) — — Unrecognized Tax Benefit — December 31, $ 1.2 $ 2.9 $ 6.3 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $0.9 million at December 31, 2017 and $2.4 million at December 31, 2016. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the year ended December 31, 2017 and 2016, the Company recognized approximately $(0.3) million and $(1.4) million , respectively, in net interest and penalties. The Company had approximately $0.2 million and $0.4 million for the payment of interest and penalties accrued at December 31, 2017 and 2016, respectively. It is reasonably possible that within the next twelve months the amount of gross unrecognized tax benefits could be reduced by approximately $0.1 million as a result of the closure of tax statutes related to existing uncertain tax positions. The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. The Company’s tax years for 2014 through 2017 remain open for examination by the Internal Revenue Service and 2013 through 2017 remain open for examination by various state and foreign taxing authorities. As a result of the Tax Act, the Company’s net unremitted foreign earnings of $136.0 million have been subject to U.S. taxation. We are currently analyzing our global working capital and cash requirements and the potential tax liabilities attributable to a repatriation, including calculating any excess of the amount for financial reporting over the tax basis in our foreign subsidiaries, but we have yet to determine whether we plan to change our prior assertion and repatriate earnings. Accordingly, we have not recorded any deferred taxes attributable to our investments in our foreign subsidiaries. We will record the tax effects of any change in our prior assertion in the period that we complete our analysis and are able to make a reasonable estimate, and disclose any unrecognized deferred tax liability for temporary differences related to our foreign investments, if practicable.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Litigation Settlement	Commitments, Contingencies and Litigation Settlement The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. Although the Company cannot precisely predict the amount of any liability that may ultimately arise with respect to any of these matters, the Company records provisions when it considers the liability probable and reasonably estimable. Our provisions are based on historical experience and legal advice, reviewed quarterly and adjusted according to developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments about potential actions by third parties, such as regulators, courts, and state and federal legislatures. Changes in the amounts of our loss provisions, which can be material, affect our financial condition. Due to the inherent uncertainties in the process undertaken to estimate potential losses, we are unable to estimate an additional range of loss in excess of our accruals. While it is reasonably possible that such excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that such excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position. Our subsidiaries are involved in a number of contractual and warranty related disputes. At this time, we cannot reasonably determine the probability of a loss, and the timing and amount of loss, if any, cannot be reasonably estimated. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates. IPSCO Tubulars Inc. d/b/a TMK IPSCO sued Ajax Tocco Magnethermic Corporation (“ATM”), a subsidiary of ParkOhio, in the United States District Court for the Eastern District of Arkansas claiming that equipment supplied by ATM for heat treating certain steel pipe at IPSCO's Blytheville, Arkansas facility did not perform as required by the contract. The complaint alleged causes of action for breach of contract, gross negligence and constructive fraud. IPSCO sought approximately $10.0 million in damages plus an unspecified amount of punitive damages. In September 2013, the district court issued a judgment in favor of IPSCO in the amount of $5.2 million , which the Company recognized and accrued for at that time. In March 2016, the district court issued an order granting, in part, IPSCO's motion for fees and costs and awarding $2.2 million to IPSCO, which the Company accrued for as of December 31, 2015. ATM filed a third appeal of that decision. On March 28, 2017, the Company and IPSCO agreed to a settlement and release of all claims for the payment by the Company of $4.0 million to IPSCO, which was made in March 2017. As of the settlement date, the Company had $7.3 million accrued for this matter. The Company reversed the excess liability and recognized $3.3 million in income in the first quarter of 2017. In August 2013, the Company received a subpoena from the staff of the Securities and Exchange Commission (“SEC”) in connection with the staff’s investigation of a third party. At that time, the Company also learned that the U.S. Department of Justice (“DOJ”) is conducting a criminal investigation of the third party. In connection with its initial response to the staff’s subpoena, the Company disclosed to the staff of the SEC that, in November 2007, the third party participated in a payment on behalf of the Company to a foreign tax official that implicates the Foreign Corrupt Practices Act. Holdings' Board of Directors formed a special committee to review the Company's transactions with the third party and to make any recommendations to the Holdings' Board of Directors with respect thereto. The Company intends to cooperate fully with the SEC and the DOJ in connection with their investigations of the third party and with the SEC in light of the Company’s disclosure. The Company is unable to predict the outcome or impact of the special committee’s investigation or the length, scope or results of the SEC’s review or the impact on its results of operations.

Retirement Benefits [Abstract]
Pensions and Postretirement Benefits	Pensions and Postretirement Benefits The Company and its subsidiaries have pension plans, principally noncontributory defined benefit or noncontributory defined contribution plans, covering substantially all employees. In addition, the Company has an unfunded postretirement benefit plan. One of its defined benefit plans, covering most U.S. employees not covered by collective bargaining agreements, utilizes a cash balance formula. Under a cash balance formula, a plan participant accumulates a retirement benefit consisting of pay credits that are based upon a percentage of current eligible earnings and current interest credits. For the remaining defined benefit plans, benefits are based on the employee’s years of service. For the defined contribution plans, the costs charged to operations and the amount funded are based upon a percentage of the covered employees’ compensation. The Company's objective for the pension plan is to monitor the funded ratio; create general investment goals in regards to acceptable risk and liquidity needs ensuring the long-term interests of participants and beneficiaries are considered and manage risk by minimizing the short-term and long-term risk of actual expenses and contribution requirements. The following tables set forth the changes in benefit obligation, plan assets, funded status and amounts recognized in the consolidated balance sheet for the defined benefit pension and postretirement benefit plans as of December 31, 2017 and 2016 : Pension Benefits Postretirement Benefits 2017 2016 2017 2016 (In millions) Change in benefit obligation Benefit obligation at beginning of year $ 58.5 $ 58.4 $ 10.0 $ 13.5 Service cost 2.4 2.4 — — Interest cost 1.8 1.8 0.3 0.3 Actuarial losses (gains) 2.4 0.5 0.5 (2.6 ) Benefits and expenses paid (4.6 ) (4.6 ) (1.5 ) (1.2 ) Benefit obligation at end of year $ 60.5 $ 58.5 $ 9.3 $ 10.0 Change in plan assets Fair value of plan assets at beginning of year $ 120.2 $ 117.3 $ — $ — Actual return on plan assets 20.2 8.3 — — Company contributions — — 1.5 1.2 Cash transfer to fund postretirement benefit payments (1.0 ) (0.8 ) — — Benefits and expenses paid (4.6 ) (4.6 ) (1.5 ) (1.2 ) Fair value of plan assets at end of year $ 134.8 $ 120.2 $ — $ — Funded (underfunded) status of the plans $ 74.3 $ 61.7 $ (9.3 ) $ (10.0 ) Amounts recognized in the consolidated balance sheets consist of: Pension Benefits Postretirement Benefits 2017 2016 2017 2016 (In millions) Pension assets $ 74.3 $ 61.7 $ — $ — Other current liabilities — — 1.1 1.2 Other long-term liabilities — — 8.2 8.8 $ 74.3 $ 61.7 $ 9.3 $ 10.0 Amounts recognized in Accumulated other comprehensive loss Net actuarial loss $ 16.5 $ 25.8 $ 2.1 $ 1.7 Net prior service cost (credit) 0.3 0.3 (0.1 ) (0.2 ) Accumulated other comprehensive loss $ 16.8 $ 26.1 $ 2.0 $ 1.5 The pension plan weighted-average asset allocation at December 31, 2017 and 2016 and target allocation for 2018 are as follows: Plan Assets Target 2018 2017 2016 Asset Category Equity securities 45-75% 65.0 % 61.9 % Debt securities 20-40% 23.6 % 24.6 % Other 0-20% 11.4 % 13.5 % 100% 100 % 100 % The following table sets forth, by level within the fair value hierarchy, the pension plans assets: 2017 2016 Level 1 Total (at Fair Value) Level 1 Total (at Fair Value) (In millions) Common stock $ 41.8 $ 41.8 $ 40.0 $ 40.0 Equity securities 39.8 39.8 29.0 29.0 Foreign stock 7.3 7.3 5.4 5.4 U.S. Government obligations 5.8 5.8 8.1 8.1 Fixed income securities 13.7 13.7 14.1 14.1 Corporate Bonds 10.2 10.2 6.3 6.3 Cash and cash equivalents 1.4 1.4 3.3 3.3 Total $ 120.0 $ 106.2 Investments measured at net asset value: Common collective trusts 0.7 1.1 Hedge funds 14.1 12.9 Total assets at fair value $ 134.8 $ 120.2 Valuation Methodologies: Following is a description of the valuation methodologies used for pension plan assets measured at fair value. There have been no changes in the methodologies used at December 31, 2017 and 2016. Common stock, equity securities and foreign stock - These securities consist of direct investments in the stock of publicly-traded companies. Such investments are valued based on the closing price reported in an active market on which the individual securities are traded. As such, the direct investments are classified as Level 1. U.S. Government obligations, fixed income securities and corporate bonds - Valued at the closing price of each security. Cash equivalents - Consists of primarily money market funds and certificates of deposit, for which book value equals fair value. Common collective trusts - Valued at the net unit value of units held by the trust at year end. The unit value is determined by the total value of fund assets divided by the total number of units of the fund owned. The equity investments in collective trusts are predominantly in index funds for which the underlying securities are actively traded in public markets based upon readily measurable prices. Common collective trusts are measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables above to permit a reconciliation of the fair value hierarchy to the total plan assets. Hedge funds - Consists of direct investments in hedge funds through limited partnership interests. Net asset values are based on the estimated fair value of the ownership interest in the investment as determined by the General Partner. The majority of the holdings of the hedge funds are in equity securities traded on public exchanges. The investment terms of the hedge funds allow capital to be redeemed quarterly given prior notice with certain limitations. Hedge funds measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables above to permit a reconciliation of the fair value hierarchy to the total plan assets. For additional information regarding fair value measurements, see Note 1. The following tables summarize the assumptions used in the valuation of pension and postretirement benefit obligations at December 31 and the measurement of the net periodic benefit cost in the following year. The Company used a spot rate approach by applying the specific spot rates along the yield curve to the relevant projected cash flows in the estimation of the service and interest components of benefit cost.

This assumption was supported by the asset return generation model, which projected future asset returns using simulation and asset class correlation.

The estimated net loss and prior service cost for the postretirement plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the year ending December 31, 2018 is less than $ 0.1 million . Below is a table summarizing the Company’s expected future benefit payments and the expected payments due to Medicare subsidy over the next ten years: Postretirement Benefits Pension Benefits Gross Expected Medicare Subsidy Net including Medicare Subsidy (In millions) 2018 $ 5.1 $ 1.2 $ 1.1 $ 0.1 2019 4.4 1.1 1.0 0.1 2020 4.5 1.0 0.9 0.1 2021 4.6 0.9 0.8 0.1 2022 4.4 0.9 0.8 0.1 2023 to 2027 22.8 3.6 3.2 0.4 The Company expects to make no contributions to its defined benefit plans in 2018 and beyond, as pension benefits are expected to be paid out of plan assets and postretirement benefits are paid directly by the Company. Under the postretirement benefit plan, health care benefits are provided on both a contributory and noncontributory basis. The assumed health care cost trend rate has a significant effect on the amounts reported. A one-percentage-point change in the assumed health care cost trend rate would have the following effects: 1-Percentage Point Increase 1-Percentage Point Decrease (In millions) Effect on total of service and interest cost components in 2017 $ — $ — Effect on postretirement benefit obligation as of December 31, 2017 $ 0.6 $ (0.6 ) In January 2008, a Supplemental Executive Retirement Plan (“SERP”) for the Company’s Chairman and Chief Executive Officer (“CEO”) was approved by the Compensation Committee of the Board of Directors of the Company. The SERP provides an annual supplemental retirement benefit for up to $0.4 million upon the CEO’s termination of employment with the Company. The vested retirement benefit will be equal to a percentage of the SERP that is equal to the ratio of (1) his credited service with the Company prior to January 1, 2008 (up to a maximum of thirteen years), plus his credited service after January 1, 2008 (up to a maximum of seven years); to (2) twenty years of credited service. In the event of a change in control before the CEO’s termination of employment, he will receive 100% of the SERP. The Company recorded income of $0.2 million in 2017 and 2016 and expense of $0.6 million in 2015 related to the SERP.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Consolidation and Basis of Presentation	Consolidation and Basis of Presentation: Park-Ohio Industries, Inc. (“ParkOhio,” “we” or the “Company”) is a diversified international company providing world-class customers with a supply chain management outsourcing service, capital equipment used on their production lines, and manufactured components used to assemble their products. The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. The consolidated financial statements include the accounts of the Company and all of its majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company does not have off-balance sheet arrangements or financings with unconsolidated entities or other persons. The Company leases certain real properties owned by related parties as described in Note 10. Transactions with related parties are not material to the Company’s financial position, results of operations or cash flows.
Accounting Estimates	Accounting Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements. Actual results could differ from those estimates.
Cash Equivalents	Cash Equivalents: The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts: Accounts receivable are recorded at net realizable value. Accounts receivable are reduced by an allowance for amounts that may become uncollectable in the future. The allowance for doubtful accounts was $4.5 million and $4.0 million at December 31, 2017 and 2016, respectfully. The Company’s policy is to identify and reserve for specific collectability concerns based on customers’ financial condition and payment history, as well as a general reserve based on historical trends and other information. During 2017 and 2016 , we sold approximately $80.0 million and $81.6 million , respectively, of accounts receivable to mitigate accounts receivable concentration risk and to provide additional financing capacity. In compliance with ASC 860, “Transfers and Servicing”, sales of accounts receivable are reflected as a reduction of accounts receivable in the Consolidated Balance Sheets and the proceeds are included in cash flows from operating activities in the Consolidated Statements of Cash Flows.
Inventories	Inventories: Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or net realizable value.
Property, Plant and Equipment	Property, Plant and Equipment: Property, plant and equipment is carried at cost. Additions and improvements that extend the lives of assets are capitalized and expenditures for repairs and maintenance are charged to operations as incurred. Depreciation and amortization of fixed assets, including capital leases, is computed principally by the straight-line method based on the estimated useful lives of the assets ranging from five to 40 years for buildings, and one to 20 years for machinery and equipment (with the majority in the range of three to ten years).
Goodwill and Indefinite-Lived Assets	Goodwill and Indefinite-Lived Assets: In accordance with Accounting Standards Codification (“ASC”) 350, “ Intangibles — Goodwill and Other ” (“ASC 350”), goodwill and indefinite life intangible assets are not amortized, but rather are tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be an indicator of impairment in accordance with ASC 350 . Goodwill is tested for impairment at the reporting unit level and is based on the net assets for each reporting unit, including goodwill and intangible assets, compared to the fair value. Our reporting units have been identified at the component level. The Company completed its annual goodwill and indefinite-lived intangibles impairment testing as of October 1 of each year, noting no impairment. The Company uses an income approach, utilizing a discounted cash flow model based on forecasted cash flows and weighted average cost of capital, and other valuation techniques to determine fair value.
Impairment of Long-Lived Assets	Impairment of Other Long-Lived Assets: Other long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Upon indications of impairment, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The asset group would be considered impaired when the estimated future net undiscounted cash flows generated by the asset group are less than its carrying value.
Fair Values of Financial Instruments	Fair Values of Financial Instruments: Certain financial instruments are required to be recorded at fair value. The Company measures financial assets and liabilities at fair value in three levels of inputs. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and borrowings under the Credit Agreement (as defined in Note 6) approximate fair value at December 31, 2017 and December 31, 2016 because of the short-term nature of these instruments. The fair values of long-term debt and pension plan assets are disclosed in Note 6 and Note 11, respectively. The Company has not changed its valuation techniques for measuring fair value during 2017 , and there were no transfers between levels during the periods presented.
Income Taxes	Income Taxes: The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and the tax bases of assets and liabilities and are measured using the current enacted tax rates. In determining these amounts, management determined the probability of realizing deferred tax assets, taking into consideration factors including historical operating results, cumulative earnings and losses, expectations of future earnings, taxable income and the extended period of time over which the postretirement benefits will be paid and accordingly records valuation allowances if, based on the weight of available evidence it is more likely than not that some portion or all of our deferred tax assets will not be realized as required by ASC 740, “Income Taxes” (“ASC 740”).
Share-Based Compensation	Share-Based Compensation: The Company follows the provisions of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their grant date fair values. Compensation expense for awards with service conditions only that are subject to graded vesting is recognized on a straight-line basis over the term of the vesting period. Compensation expense of performance-based awards is recognized as an expense over the vesting periods of the awards using the accelerated attribution method once performance is deemed probable. Park-Ohio Holdings Corp. (“Holdings”) grants share-based compensation awards to Industries' employees. In accordance with ASC 718, such costs are allocated to Industries. Under the provisions of Holdings’ 2015 Equity and Incentive Compensation Plan (“2015 Plan”), which is administered by the Compensation Committee of Holdings' Board of Directors, incentive stock options, non-statutory stock options, stock appreciation rights (“SARs”), restricted share units, performance shares or stock awards may be awarded to directors and all employees of the Company and its subsidiaries. The 2015 Plan replaces in its entirety the 1998 Long-Term Incentive Plan, as amended (“1998 Plan”), but shares that remained available under the 1998 Plan were added to the aggregate share limit under that 2015 Plan. Stock options will be exercisable in whole or in installments as may be determined provided that no options will be exercisable more than ten years from date of grant. The exercise price will be the fair value at the date of grant. The aggregate number of shares of Holdings' common stock that may be awarded under the 2015 Plan is 98,586 .
Revenue Recognition	Revenue Recognition: The Company recognizes revenue, other than from long-term contracts, when title is transferred to the customer, typically upon shipment. Revenue from long-term contracts is accounted for under the percentage of completion method, and recognized on the basis of the percentage each contract’s cost to date bears to the total estimated contract cost. We follow this method since reasonably reliable estimates of revenue and costs of a contract can be made.
Cost of Sales	Cost of Sales : Cost of sales is primarily comprised of direct materials and supplies consumed in the manufacture of product; manufacturing labor, depreciation expense and direct overhead expense; and shipping and handling costs.
Concentration of Credit Risk	Concentration of Credit Risk: The Company sells its products to customers in diversified industries. The Company performs ongoing credit evaluations of its customers’ financial condition but does not require collateral to support customer receivables. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information.
Environmental	Environmental: The Company expenses environmental costs related to existing conditions resulting from past or current operations and from which no current or future benefit is discernible. Costs that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. The Company records a liability when environmental assessments and/or remedial efforts are probable and can be reasonably estimated. The estimated liability of the Company is not reduced for possible recoveries from insurance carriers and is undiscounted.
Foreign Currency Translation	Foreign Currency Translation: The functional currency for a majority of subsidiaries outside the United States is the local currency. Financial statements for these subsidiaries are translated into U.S. dollars at year-end exchange rates for assets and liabilities and weighted-average exchange rates for revenues and expenses. The resulting translation adjustments are recorded in Accumulated other comprehensive income (loss) in shareholder's equity. Gains and losses resulting from foreign currency translations, including intercompany transactions that are not considered permanent investments, are included in the Consolidated Statements of Income.
Warranty Liabilities	Warranties: The Company estimates the amount of warranty claims on sold products that may be incurred based on current and historical data. The actual warranty expense could differ from the estimates made by the Company based on product performance.
Accounting Pronouncements Adopted and Recent Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Adopted In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The ASU simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows. The Company adopted this ASU effective January 1, 2017. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies resulting from share-based compensation awards vesting and exercises be recognized as a discrete income tax adjustment in the income statement. Previously, these amounts were recognized in Additional paid-in capital. In 2017, the Company recognized income tax expense of $0.2 million for excess tax deficiencies upon vesting of awards. In addition, ASU 2016-09 requires excess tax benefits and shortfalls to be prospectively excluded from the assumed future proceeds in the calculation of diluted shares. ASU 2016-09 also requires that excess tax benefits from share-based compensation awards be reported as operating activities in the Consolidated Statements of Cash Flows. Previously, this activity was included in financing activities on the Consolidated Statements of Cash Flows. The Company has elected to apply this change on a prospective basis. This change has an immaterial impact on our Consolidated Statements of Cash Flows. Also, we elected to continue to estimate forfeitures rather than account for them as they occur. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill impairment." The amendments in the ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The ASU is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company early adopted this guidance for its October 1, 2017 impairment test. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, a comprehensive new revenue recognition standard that will supersede existing guidance under U.S. GAAP. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Our implementation efforts included the identification of revenue within the scope of the standard, the evaluation of revenue contracts under the guidance, and assessing the impacts of the new standard on our financial statements. The new standard is effective for the Company for the first quarter of 2018, and we will utilize the modified retrospective method of adoption. This method allows companies to record a one-time adjustment to beginning retained earnings as of January 1, 2018 for the cumulative effect that the standard will have on open contracts at the date of adoption. During our implementation, we identified certain contracts which will require over time recognition under the new standard, either as goods are manufactured or services are performed, rather than at the time of shipment or completion as we do under existing guidance. Upon adoption, we expect to accelerate approximately $13 million to $17 million of revenue, resulting in a cumulative-effect adjustment of approximately $2 million to $4 million to our 2018 beginning retained earnings. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The Board also is addressing measurement of credit losses on financial assets in a separate project. This ASU is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is not permitted. The new guidance will be applied prospectively and is expected to have an immaterial impact on the financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The amendment establishes a comprehensive new lease accounting model. The new standard: (a) clarifies the definition of a lease; (b) requires a dual approach to lease classification similar to current lease classifications; and (c) causes lessees to recognize leases on the balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease-term of more than twelve months. This ASU is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a modified retrospective transition for capital or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements, but it does not require transition accounting for leases that expire prior to the date of initial application. The Company is currently evaluating the impact of adopting this guidance. In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The ASU requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The Company will adopt this standard on the required date of January 1, 2018. The Company is currently evaluating the impact of adopting this guidance. No other recently issued ASUs are expected to have a material impact on our results of operations, financial condition or liquidity.
Segments	The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. Supply Technologies provides our customers with Total Supply Management™ services for a broad range of high-volume, specialty production components. Assembly Components manufactures cast aluminum components, automotive and industrial rubber and thermoplastic products, gasoline direct injection systems, fuel filler and hydraulic assemblies for automotive, agricultural equipment, construction equipment, heavy-duty truck and marine equipment industries, and also provides value-added services such as design and engineering, machining and assembly. Engineered Products operates a diverse group of niche manufacturing businesses that design and manufacture a broad range of high quality products engineered for specific customer applications. For purposes of measuring business segment performance, the Company utilizes segment operating income, which is defined as revenues less expenses identifiable to the product lines within each segment. The Company does not allocate items that are non-operating; unusual in nature; or are corporate costs, which include but are not limited to executive compensation and corporate office costs. Segment operating income reconciles to consolidated income before income taxes by deducting corporate costs, certain non-cash charges and interest expense.
Commitments and Contingencies	The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. Although the Company cannot precisely predict the amount of any liability that may ultimately arise with respect to any of these matters, the Company records provisions when it considers the liability probable and reasonably estimable. Our provisions are based on historical experience and legal advice, reviewed quarterly and adjusted according to developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments about potential actions by third parties, such as regulators, courts, and state and federal legislatures. Changes in the amounts of our loss provisions, which can be material, affect our financial condition. Due to the inherent uncertainties in the process undertaken to estimate potential losses, we are unable to estimate an additional range of loss in excess of our accruals. While it is reasonably possible that such excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that such excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position. Our subsidiaries are involved in a number of contractual and warranty related disputes. At this time, we cannot reasonably determine the probability of a loss, and the timing and amount of loss, if any, cannot be reasonably estimated. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates.
