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 11. 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 an original 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 $6.2 million and $4.5 million at December 31, 2018 and 2017 , respectively. 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 2018 and 2017 , we sold approximately $106.8 million and $80.0 million , respectively, of accounts receivable to mitigate accounts receivable concentration risk and to increase working capital efficiency. 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 2018 and 2017 , expense in the amount of $1.0 million and $0.6 million , respectively, related to the discount on sale of accounts receivable is recorded in the Consolidated Statements of Income. Inventories: Inventories are valued using first-in, first-out (“FIFO”) or the weighted-average inventory method and stated at the lower of cost or net realizable value, except for the inventories at Canton Drop Forge (“CDF”), which was acquired on February 1, 2018. CDF inventories are stated using the last-in, first-out (“LIFO”) method. Major Classes of Inventories December 31, 2018 December 31, 2017 Raw materials and supplies $ 85.0 $ 67.6 Work in process 48.9 43.9 Finished goods 182.0 171.3 LIFO reserve 1.9 — Inventories, net $ 317.8 $ 282.8 Other Inventory Items Inventory reserves $ (34.9 ) $ (29.8 ) Consigned inventory $ 10.3 $ 9.8 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, Land and land improvements $ 11.8 $ 11.5 Buildings 84.4 76.1 Machinery and equipment 392.6 348.6 Leased property under capital leases 35.8 24.1 Total property, plant and equipment 524.6 460.3 Less: Accumulated depreciation 302.7 280.8 Property, plant and equipment, net $ 221.9 $ 179.5 Information regarding depreciation expense of property, plant and equipment follows: Year Ended December 31, 2018 2017 2016 Depreciation expense $ 29.3 $ 24.9 $ 23.5 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 of each reporting unit, including goodwill and intangible assets, compared to its 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. To determine fair value, the Company uses primarily an income approach, utilizing a discounted cash flow model based on forecasted cash flows and weighted average cost of capital for its goodwill testing, and a relief of royalty method for its indefinite-lived intangibles testing. See Notes 5 and 6 of the consolidated financial statements for additional disclosures about 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 as follows: 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, 2018 and December 31, 2017 because of the short-term nature of these instruments. The fair values of long-term debt and pension plan assets are disclosed in Note 7 and Note 12, respectively. The Company has not changed its valuation techniques for measuring fair value during 2018 , 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. As required by ASC 740, “Income Taxes” (“ASC 740”), the Company records valuation allowances if, based on the weight of available evidence, it is more likely than not that all or some portion of our deferred tax assets will not be realized. Revenue Recognition: The Company recognizes revenue, other than from long-term contracts within the Engineered Products segment, when its obligations under the contract terms are satisfied and control transfers to the customer, typically upon shipment. Revenue from certain long-term contracts is accounted for over time, when products are manufactured or services are performed, as control transfers under these arrangements. We follow this method since reasonably reliable estimates of revenue and costs of a contract can be made. See Note 2 for additional disclosure on revenue. 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, 2018 , the Company had uncollateralized receivables with six customers in the automotive industry, each with several locations, aggregating $ 46.8 million , which represented approximately 18% of the Company’s trade accounts receivable. During 2018 , sales to these customers amounted to approximately $ 338.2 million , which represented approximately 20% 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 of the Company's subsidiaries outside the United States is the local currency. Financial statements are translated into U.S. dollars at year-end exchange rates for assets and liabilities and weighted-average exchange rates during the period for revenues and expenses. The resulting translation adjustments are recorded in Accumulated other comprehensive income (loss) in shareholders’ equity. Gains and losses resulting from foreign currency transactions, including intercompany transactions that are not considered long-term 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, 2018 2017 2016 Balance at January 1, $ 7.9 $ 7.1 $ 6.1 Claims paid during the year (5.3 ) (4.0 ) (3.7 ) Warranty expense 3.6 4.7 2.0 Acquired warranty liabilities — 0.1 2.8 Other — — (0.1 ) Balance at December 31, $ 6.2 $ 7.9 $ 7.1 Accounting Pronouncements Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” a new comprehensive revenue recognition standard that supersedes previous 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 identification of revenue within the scope of the standard, evaluation of revenue contracts under the guidance, and an assessment of the impacts of the new standard on our consolidated financial statements. The Company adopted the new standard as of January 1, 2018 using the modified retrospective method of adoption. This method allowed companies to record a one-time adjustment to beginning retained earnings as of January 1, 2018 for the cumulative effect that the standard had on open contracts at the date of adoption. During our implementation, we identified certain contracts that now 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 recorded under previous guidance. Upon adoption, we recorded previously unrecognized revenue of $13.6 million , resulting in a cumulative-effect adjustment of $2.6 million to our 2018 beginning retained earnings. See Note 2 for further details. 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 adopted this standard effective January 1, 2018. Other components of pension income and other postretirement benefits expense, net includes all amounts other than the service cost component. Such amounts are included on a separate line below operating income on the condensed consolidated statements of income. The new standard requires a retrospective application and allows a practical expedient that permits an employer to use the amounts disclosed in its pension footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation. This resulted in the reclassification of the following amounts from previously-reported Selling, general and administrative (“SG&A”) expenses for 2017 and 2016: Year Ended December 31, 2017 2016 Amounts recorded in Cost of sales $ (1.8 ) $ (1.8 ) Amounts recorded in SG&A expenses (0.6 ) $ (0.6 ) Amounts recorded in Other components of pension income and other postretirement benefits expenses, net 6.4 $ 6.2 Total pension income and other postretirement benefits expense, net $ 4.0 $ 3.8 Recent Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This accounting standard requires that a lessee recognize a lease asset and a lease liability on its balance sheet for all leases, including operating leases, with a term greater than 12 months. ASU 2016-02 will require additional disclosures in the notes to the consolidated financial statements and is effective for the Company as of January 1, 2019. In July 2018, the FASB issued updated guidance which allows an additional transition method to adopt the new leases standard at the adoption date, rather than as of the beginning of the earliest period presented, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings in the period of adoption. The Company has elected this transition method at the date of adoption. The Company has elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allows it to carry forward historical lease classifications. The Company also made an accounting policy election not to record a right-of-use asset or lease liability related to leases with an initial term of 12 months or less. The Company recognizes these lease payments in the consolidated income statements on a straight-line basis over the lease term. The Company’s implementation team has identified its population of leases; is concluding its testing of the functionality and related controls of its new third-party lease software; is finalizing its incremental borrowing rate; and is determining the quantitative impact as of the transition date. An estimate of the impact on the consolidated financial statements cannot be made at this time. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments,” which replaces the current incurred loss impairment model with a methodology that reflects expected credit losses. Under the new methodology, entities will be required to measure expected credit losses on financial instruments held at amortized cost, including trade receivables, based on historical experience, current conditions and reasonable forecasts. Adoption of this guidance is required for interim and annual periods beginning after December 15, 2019, with early adoption permitted for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the expected impact of this standard. In February 2018, the FASB issued ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The ASU affects any entity that is required to apply the provisions of Topic 220, “Income Statement—Reporting Comprehensive Income,” and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The ASU is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a retrospective application to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (the “TCJA”) is recognized. The Company is currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued Accounting Standards Update 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement,” which changes the requirements on fair value measurements by removing, modifying or adding certain disclosures. Adoption of this guidance is required for interim and annual periods beginning after December 15, 2019 with early adoption permitted. The Company is currently evaluating the expected impact of this standard. No other recently issued ASUs are expected to have a material impact on our results of operations, financial condition or liquidity.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue As discussed above in Note 1, effective January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers.” Substantially all of the Company’s contracts have a single performance obligation to transfer products to or, in limited cases, perform services for the customer. Accordingly, the Company recognizes revenue when its obligations under the contract terms are satisfied and control transfers to the customer. Revenue is recognized at an amount that reflects the consideration the Company expects to receive in exchange for the good or service, including estimated provisions for rebates, discounts, returns and allowances. The Company sells its products both directly to customers, and in limited cases, through distributors, generally under agreements with payment terms between 30 - 90 days; the Company has no financing components. The majority of the Company’s revenue is derived from contracts (i) with an original contract length of one year or less, or (ii) for which it recognizes revenue at the amount at which it has the right to invoice as products or services are delivered. The Company has elected the practical expedient not to disclose the value of remaining performance obligations associated with these types of contacts. The Company also has certain contracts which contain performance obligations that are immaterial in the context of the contract with the customer. The Company has elected the practical expedient not to assess whether these promised goods or services are performance obligations. Supply Technologies provides our customers with Total Supply Management™, a proactive solutions approach that manages the efficiencies of every aspect of supplying production parts and materials to our customers’ manufacturing floor, from strategic planning to program implementation. Within this segment, contracts routinely consist of a long-term agreement or master service agreement with quantity and pricing specified through individual purchase orders. Revenue is recognized at a point in time, which is in almost all cases is at the shipping point, as that is when control transfers to the customer. Assembly Components designs, develops and manufactures: aluminum products; highly efficient, high pressure direct fuel injection fuel rails and pipes; fuel filler pipes that route fuel from the gas cap to the gas tank; and flexible multi-layer plastic and rubber assemblies used to transport fuel from the vehicle's gas tank and then, at extreme high pressure, to the engine's fuel injector nozzles. Within this segment, contracts routinely consist of a long-term agreement or master service agreement with quantity and pricing specified through individual purchase orders. Revenue is recognized at a point in time, which is at the shipping point, as that is when control transfers to the customer. Engineered Products operates a diverse group of niche manufacturing businesses that design and manufacture a broad range of highly-engineered products, including induction heating and melting systems, pipe threading systems and forged and machined products. Engineered Products also produces and provides services and spare parts for the equipment it manufactures. In this segment, revenue is recognized for certain revenue streams at a point in time, and over time for other revenue streams. For point in time arrangements, revenue is recognized at the shipping point, as that is when control transfers to the customer. For over time arrangements, revenue is recognized over the time during which products are manufactured or services are performed, as control transfers under these arrangements over a period of time. Over time arrangements represent 16% of the Company's total consolidated sales for the year ended December 31, 2018. The Company uses the input method to calculate the contract revenues to be recognized, which utilizes costs incurred to date in relation to total expected costs to satisfy the Company’s performance obligation under the contract. Incurred costs represent work performed and therefore best depict the transfer of control to the customer. For over time arrangements, contract liabilities primarily relate to advances or deposits received from the Company’s customers before revenue is recognized. These amounts, which totaled $39.5 million and $23.0 million at December 31, 2018 and December 31, 2017, respectively, are recorded as Deferred revenue in the Consolidated Balance Sheets. For over time arrangements, contract assets primarily relate to revenue recognized in advance of billings to customers under long-term contracts accounted for under percentage of completion. These amounts, which totaled $66.3 million and $44.5 million at December 31, 2018 and December 31, 2017, respectively, are recorded as Unbilled contract revenue in the Consolidated Balance Sheets. The adoption of ASU 2014-09 had the impact of increasing unbilled contract revenue by $13.6 million , reducing inventory by $10.1 million , increasing accrued income taxes by $0.9 million and increasing beginning retained earnings by $2.6 million as of January 1, 2018. The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer its products. As such, shipping and handling fees billed to customers in a sales transaction are recorded in Net sales, and shipping and handling costs incurred are recorded in Cost of sales. The Company has elected to exclude from Net sales any value-added, sales or other taxes which it collects concurrent with revenue-producing activities. These accounting policy elections are consistent with the manner in which the Company historically recorded shipping and handling fees and expenses. We disaggregate our revenue by product line and geographic region of our customer, as we believe these best depict how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors.

Income Taxes	Income Taxes Income before income taxes consists of the following: Year Ended December 31, 2018 2017 2016 United States $ 36.0 $ 22.2 $ 16.3 Outside the United States 36.7 26.3 25.6 $ 72.7 $ 48.5 $ 41.9 Income taxes consists of the following: Year Ended December 31, 2018 2017 2016 Current expense (benefit): Federal $ 6.6 $ 14.0 $ 0.3 State 0.6 0.6 0.2 Foreign 9.0 7.6 6.6 16.2 22.2 7.1 Deferred expense (benefit): Federal 1.3 (5.5 ) 0.9 State 0.1 0.3 0.5 Foreign (0.8 ) 0.7 0.7 0.6 (4.5 ) 2.1 Income tax expense $ 16.8 $ 17.7 $ 9.2 The TCJA was enacted on December 22, 2017. The TCJA reduced the US federal corporate tax rate from 35% to 21% , required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, created new taxes on its global intangible low-taxed income (“GILTI”), and provided a foreign-derived intangible income deduction (“FDII”). In 2017 and the first nine months of 2018, we recorded provisional amounts for certain enactment date effects of the TCJA by applying the guidance in Staff Accounting Bulletin (“SAB”) 118 because we had not yet completed our enactment-date accounting for these effects. During the fourth quarter of 2018, the Company finalized its accounting for the 2017 enactment of the TCJA and recorded net expense of $0.3 million related to the remeasurement of taxes and the one-time transition tax. The TCJA subjects a US shareholder to tax on GILTI earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense. We have elected to account for GILTI as a current period expense. The impact of GILTI at December 31, 2018 was an increase in tax expense of $3.1 million . The impact of FDII at December 31, 2018 was a decrease in tax expense of $0.6 million . A reconciliation of income tax expense computed by applying the statutory federal income tax rate to income tax expense as recorded is as follows: Year Ended December 31, 2018 2017 2016 Income tax at U.S. statutory rate $ 15.3 $ 16.9 $ 14.7 Effect of state income taxes, net 0.6 0.7 0.2 Effect of foreign operations 3.5 (5.2 ) (2.1 ) Valuation allowance (3.0 ) 5.3 0.5 Uncertain tax positions (0.3 ) (2.0 ) (4.0 ) Non-deductible items 0.5 0.5 0.6 Non-deductible compensation 0.8 0.4 0.8 Manufacturer's deduction — (0.8 ) (0.5 ) Foreign tax credit (2.2 ) — — GILTI 3.1 — — FDII (0.6 ) — — Net impact of TCJA 0.3 3.3 — Other, net (1.2 ) (1.4 ) (1.0 ) Income tax as recorded $ 16.8 $ 17.7 $ 9.2 Significant components of the Company’s net deferred income tax assets and liabilities are as follows: Year Ended December 31, 2018 2017 Deferred income tax assets: Postretirement benefit obligation $ 1.8 $ 2.0 Inventory 8.5 9.9 Net operating loss and credit carryforwards 11.4 16.1 Warranty reserve 0.3 0.4 Accrued litigation 0.1 0.1 Compensation 4.7 4.2 Disallowed interest 2.7 — Other 3.2 4.9 Total deferred income tax assets 32.7 37.6 Deferred income tax liabilities: Depreciation and amortization 18.3 10.4 Pension 12.3 16.3 Intangible assets 16.1 16.6 Other 3.2 3.3 Total deferred income tax liabilities 49.9 46.6 Net deferred income tax liabilities prior to valuation allowances (17.2 ) (9.0 ) Valuation allowances (5.3 ) (11.6 ) Net deferred income tax liability $ (22.5 ) $ (20.6 ) At December 31, 2018 , 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 $26.5 million , of which $8.9 million expires between 2019 and 2038 and the remainder has no expiration date. The Company has a tax benefit from a state net operating loss carryforward of $2.2 million that expires between 2019 and 2038 . The Company also has a tax benefit from a non-consolidated U.S. net operating loss carryforward of $1.4 million that expires between 2035 and 2036 . The foreign tax credit carryforward is $0.1 million and expires in 2028 . As of December 31, 2018 and 2017 , 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 year ended December 31, 2018, the Company recorded a tax benefit of $6.3 million related to the reversal of valuation allowance, of which $3.0 million was recorded in income tax expense with the remainder reflected in deferred taxes. For the year ended December 31, 2017, the Company recorded tax expense of $6.3 million related to valuation allowance against certain foreign net deferred tax assets and the U.S. foreign tax credits which are not expected to be realizable. 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: 2018 2017 2016 Unrecognized Tax Benefit — January 1, $ 1.2 $ 2.9 $ 6.3 Gross Increases to Tax Positions Related to Current Year 0.1 0.1 — Gross Increases to Tax Positions Related to Prior Years — 0.6 0.3 Gross Decreases to Tax Positions Related to Prior Years (0.1 ) — — Gross Decreases related to settlements with Taxing Authorities (0.1 ) (0.4 ) — Expiration of Statute of Limitations (0.2 ) (1.9 ) (3.7 ) Other — (0.1 ) — Unrecognized Tax Benefit — December 31, $ 0.9 $ 1.2 $ 2.9 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $0.8 million at December 31, 2018 and $0.9 million at December 31, 2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the years ended December 31, 2018 and 2017, the Company recognized a tax benefit of approximately $0.1 million and $0.3 million , respectively, in net interest and penalties due to the expiration of various uncertain tax positions. The Company had approximately $0.1 million and $0.2 million for the payment of interest and penalties accrued at December 31, 2018 and 2017, 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 2015 through 2018 remain open for examination by the Internal Revenue Service and 2014 through 2018 remain open for examination by various state and foreign taxing authorities. As of December 31, 2018, the Company has accumulated undistributed earnings generated by our foreign subsidiaries of approximately $183.5 million . Because $176.5 million of such earnings have previously been subject to the one-time transition taxes required by the TCJA, any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of our foreign investments would generally be limited to foreign withholding and state income taxes. We intend, however, to indefinitely reinvest these earnings and expect future U.S. cash generation to be sufficient to meet future U.S. cash needs.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-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 achievement is deemed probable. Under the provisions of the Park-Ohio Holdings Corp. (“Holdings”) 2018 Equity and Incentive Compensation Plan (“2018 Plan”), which is administered by the Compensation Committee of the 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 Holdings' and its subsidiaries. The 2018 Plan replaces in its entirety the 2015 Long-Term Incentive Plan, as amended (“2015 Plan”), but shares that remained available under the 2015 Plan were added to the aggregate share limit under the 2018 Plan.

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. The Company records a liability for loss contingencies in the consolidated financial statements when a loss is known or considered probable and the amount can be reasonably estimated. Our provisions are based on historical experience, current information and legal advice, and they may be adjusted in the future based on new developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments and potential actions by third parties. Although it is not possible to predict with certainty the ultimate outcome or cost of these matters, the Company believes they will not have a material adverse effect on our consolidated financial statements. Our subsidiaries are involved in a number of contractual and warranty-related disputes. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates. During 2017, the Company settled a claim related to equipment provided to a customer in our Engineered Products segment. 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, Holdings 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. . With respect to our disclosure, we have not heard anything from the SEC since 2014 and we do not expect to hear anything further from it, but we will cooperate with the SEC to the extent that it requests any additional information. Accordingly, we do not plan on providing any future disclosure regarding this matter unless circumstances change.

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 objectives for the pension plan are 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, 2018 and 2017 : Pension Benefits Postretirement Benefits 2018 2017 2018 2017 Change in benefit obligation Benefit obligation at beginning of year $ 60.5 $ 58.5 $ 9.3 $ 10.0 Service cost 3.7 2.4 — — Interest cost 2.2 1.8 0.3 0.3 Actuarial losses (gains) (5.3 ) 2.4 0.4 0.5 Acquisition of CDF 14.9 — — — Benefits and expenses paid (4.8 ) (4.6 ) (1.5 ) (1.5 ) Benefit obligation at end of year $ 71.2 $ 60.5 $ 8.5 $ 9.3 Change in plan assets Fair value of plan assets at beginning of year $ 134.8 $ 120.2 $ — $ — Actual return on plan assets (12.1 ) 20.2 — — Company contributions — — 1.5 1.5 Cash transfer to fund postretirement benefit payments (1.0 ) (1.0 ) — — Acquisition of CDF 11.3 — — — Benefits and expenses paid (4.8 ) (4.6 ) (1.5 ) (1.5 ) Fair value of plan assets at end of year $ 128.2 $ 134.8 $ — $ — Funded (underfunded) status of the plans $ 57.0 $ 74.3 $ (8.5 ) $ (9.3 ) Amounts recognized in the consolidated balance sheets consist of: Pension Benefits Postretirement Benefits 2018 2017 2018 2017 Pension assets $ 57.0 $ 74.3 $ — $ — Other current liabilities — — 0.9 1.1 Other long-term liabilities — — 7.6 8.2 $ 57.0 $ 74.3 $ 8.5 $ 9.3 Amounts recognized in Accumulated other comprehensive loss Net actuarial loss $ 34.7 $ 16.5 $ 2.4 $ 2.1 Net prior service cost (credit) 0.3 0.3 (0.1 ) (0.1 ) Accumulated other comprehensive loss $ 35.0 $ 16.8 $ 2.3 $ 2.0 The pension plan weighted-average asset allocation at December 31, 2018 and 2017 and target allocation for 2019 are as follows: Plan Assets Target 2019 2018 2017 Asset Category Equity securities 45-75% 57.6 % 65.0 % Debt securities 20-40% 26.5 % 23.6 % Other 0-20% 15.9 % 11.4 % 100% 100 % 100 % The following table sets forth, by level within the fair value hierarchy, the pension plans assets: 2018 2017 Level 1 Total Level 1 Total Common stock $ 34.2 $ 34.2 $ 41.8 $ 41.8 Equity securities 37.9 37.9 39.8 39.8 Foreign stock 5.7 5.7 7.3 7.3 U.S. Government obligations 4.8 4.8 5.8 5.8 Fixed income securities 13.1 13.1 13.7 13.7 Corporate bonds 12.0 12.0 10.2 10.2 Cash and cash equivalents 6.3 6.3 1.4 1.4 Total $ 114.0 $ 120.0 Investments measured at net asset value: Common collective trusts 0.1 0.7 Hedge funds 14.1 14.1 Total assets at fair value $ 128.2 $ 134.8 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, 2018 and 2017. 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, 2019 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 2019 $ 5.4 $ 1.0 $ 0.9 $ 0.1 2020 5.6 1.0 0.9 0.1 2021 5.7 0.9 0.8 0.1 2022 5.8 0.9 0.8 0.1 2023 5.9 0.9 0.8 0.1 2024 to 2028 29.7 3.4 3.1 0.3 The Company expects to make no contributions to its defined benefit plans in 2019 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 Effect on total of service and interest cost components in 2018 $ — $ — Effect on postretirement benefit obligation as of December 31, 2018 $ 0.6 $ (0.5 ) In January 2008, a Supplemental Executive Retirement Plan (“SERP”) for the Company’s current President and former Chairman and Chief Executive Officer (“Former 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 Former CEO’s termination of employment with the Company. In the event of a change in control before the Former CEO’s termination of employment, he will receive 100% of the SERP. As of December 31, 2018, the Former CEO is fully vested in the SERP. The Company recorded income of $0.1 million in 2018 and $0.2 million in 2017 and 2016 related to the SERP. As of December 31, 2018, the Company has recorded a liability of $3.1 million related to the SERP in Other long-term liabilities.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
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 11. 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 an original 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 $6.2 million and $4.5 million at December 31, 2018 and 2017 , respectively. 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 2018 and 2017 , we sold approximately $106.8 million and $80.0 million , respectively, of accounts receivable to mitigate accounts receivable concentration risk and to increase working capital efficiency. 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 valued using first-in, first-out (“FIFO”) or the weighted-average inventory method and stated at the lower of cost or net realizable value, except for the inventories at Canton Drop Forge (“CDF”), which was acquired on February 1, 2018. CDF inventories are stated using the last-in, first-out (“LIFO”) method.
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 of each reporting unit, including goodwill and intangible assets, compared to its 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. To determine fair value, the Company uses primarily an income approach, utilizing a discounted cash flow model based on forecasted cash flows and weighted average cost of capital for its goodwill testing, and a relief of royalty method for its indefinite-lived intangibles testing.
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 as follows: 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, 2018 and December 31, 2017 because of the short-term nature of these instruments. The fair values of long-term debt and pension plan assets are disclosed in Note 7 and Note 12, respectively. The Company has not changed its valuation techniques for measuring fair value during 2018 , 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. As required by ASC 740, “Income Taxes” (“ASC 740”), the Company records valuation allowances if, based on the weight of available evidence, it is more likely than not that all or some portion of our deferred tax assets will not be realized.
Revenue Recognition	Revenue Recognition: The Company recognizes revenue, other than from long-term contracts within the Engineered Products segment, when its obligations under the contract terms are satisfied and control transfers to the customer, typically upon shipment. Revenue from certain long-term contracts is accounted for over time, when products are manufactured or services are performed, as control transfers under these arrangements. We follow this method since reasonably reliable estimates of revenue and costs of a contract can be made. See Note 2 for additional disclosure on revenue.
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 of the Company's subsidiaries outside the United States is the local currency. Financial statements are translated into U.S. dollars at year-end exchange rates for assets and liabilities and weighted-average exchange rates during the period for revenues and expenses. The resulting translation adjustments are recorded in Accumulated other comprehensive income (loss) in shareholders’ equity. Gains and losses resulting from foreign currency transactions, including intercompany transactions that are not considered long-term 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” a new comprehensive revenue recognition standard that supersedes previous 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 identification of revenue within the scope of the standard, evaluation of revenue contracts under the guidance, and an assessment of the impacts of the new standard on our consolidated financial statements. The Company adopted the new standard as of January 1, 2018 using the modified retrospective method of adoption. This method allowed companies to record a one-time adjustment to beginning retained earnings as of January 1, 2018 for the cumulative effect that the standard had on open contracts at the date of adoption. During our implementation, we identified certain contracts that now 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 recorded under previous guidance. Upon adoption, we recorded previously unrecognized revenue of $13.6 million , resulting in a cumulative-effect adjustment of $2.6 million to our 2018 beginning retained earnings. See Note 2 for further details. 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 adopted this standard effective January 1, 2018. Other components of pension income and other postretirement benefits expense, net includes all amounts other than the service cost component. Such amounts are included on a separate line below operating income on the condensed consolidated statements of income. The new standard requires a retrospective application and allows a practical expedient that permits an employer to use the amounts disclosed in its pension footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation. This resulted in the reclassification of the following amounts from previously-reported Selling, general and administrative (“SG&A”) expenses for 2017 and 2016: Year Ended December 31, 2017 2016 Amounts recorded in Cost of sales $ (1.8 ) $ (1.8 ) Amounts recorded in SG&A expenses (0.6 ) $ (0.6 ) Amounts recorded in Other components of pension income and other postretirement benefits expenses, net 6.4 $ 6.2 Total pension income and other postretirement benefits expense, net $ 4.0 $ 3.8 Recent Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This accounting standard requires that a lessee recognize a lease asset and a lease liability on its balance sheet for all leases, including operating leases, with a term greater than 12 months. ASU 2016-02 will require additional disclosures in the notes to the consolidated financial statements and is effective for the Company as of January 1, 2019. In July 2018, the FASB issued updated guidance which allows an additional transition method to adopt the new leases standard at the adoption date, rather than as of the beginning of the earliest period presented, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings in the period of adoption. The Company has elected this transition method at the date of adoption. The Company has elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allows it to carry forward historical lease classifications. The Company also made an accounting policy election not to record a right-of-use asset or lease liability related to leases with an initial term of 12 months or less. The Company recognizes these lease payments in the consolidated income statements on a straight-line basis over the lease term. The Company’s implementation team has identified its population of leases; is concluding its testing of the functionality and related controls of its new third-party lease software; is finalizing its incremental borrowing rate; and is determining the quantitative impact as of the transition date. An estimate of the impact on the consolidated financial statements cannot be made at this time. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments,” which replaces the current incurred loss impairment model with a methodology that reflects expected credit losses. Under the new methodology, entities will be required to measure expected credit losses on financial instruments held at amortized cost, including trade receivables, based on historical experience, current conditions and reasonable forecasts. Adoption of this guidance is required for interim and annual periods beginning after December 15, 2019, with early adoption permitted for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the expected impact of this standard. In February 2018, the FASB issued ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The ASU affects any entity that is required to apply the provisions of Topic 220, “Income Statement—Reporting Comprehensive Income,” and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The ASU is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a retrospective application to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (the “TCJA”) is recognized. The Company is currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued Accounting Standards Update 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement,” which changes the requirements on fair value measurements by removing, modifying or adding certain disclosures. Adoption of this guidance is required for interim and annual periods beginning after December 15, 2019 with early adoption permitted. The Company is currently evaluating the expected impact of this standard. 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 and/or non-operating items; Other components of pension income and other postretirement benefits (“OPEB”) expense, net; and interest expense.
Commitments and Contingencies	The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. The Company records a liability for loss contingencies in the consolidated financial statements when a loss is known or considered probable and the amount can be reasonably estimated. Our provisions are based on historical experience, current information and legal advice, and they may be adjusted in the future based on new developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments and potential actions by third parties. Although it is not possible to predict with certainty the ultimate outcome or cost of these matters, the Company believes they will not have a material adverse effect on our consolidated financial statements.
