Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Consolidation and Basis of Presentation: Park-Ohio Holdings Corp. (“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.

Inventories: Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or market value.



Major Classes of Inventories	December 31, 2016			December 31, 2015
	(In millions)
Finished goods	$	131.4		$	147.5
Work in process	43.4			37.4
Raw materials and supplies	65.8			64.1
Inventories, net	$	240.6		$	249.0

Other inventory items
Inventory reserves	$	(30.2	)	$	(29.0	)
Consigned Inventory	$	12.2		$	10.3

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, 2016		December 31, 2015
Property, plant and equipment:
Land and land improvements	$	11.3	$	8.5
Buildings	74.9		65.3
Machinery and equipment	316.1		304.6
Leased property under capital leases	20.4		16.2
Total property, plant and equipment	422.7		394.6
Less accumulated depreciation	255.6		243.3
Property, plant and equipment, net	$	167.1	$	151.3

Information regarding depreciation expense of property, plant and equipment follows:



	Year Ended December 31,
	2016		2015		2014

Depreciation expense	$	23.4	$	22.3	$	18.4

Impairment of Long-Lived Assets: We assess the recoverability of long-lived assets (excluding goodwill) and identifiable acquired intangible assets with finite useful lives whenever impairment indicators exist. When impairment indicators exist, we measure the recoverability of assets to be held and used by a comparison of the carrying amount of the asset to the expected net future undiscounted cash flows to be generated by that asset. The amount of impairment of identifiable

intangible assets with finite useful lives, if any, to be recognized is measured based on projected discounted future cash flows.

We measure the amount of impairment of other long-lived assets (excluding goodwill) as the amount by which the carrying

value of the asset exceeds the fair value of the asset, which is generally determined, based on projected discounted future cash

flows or appraised values.

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 mode 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.

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, 2016 and December 31, 2015 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 2016, 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.

Under the provisions of the Company’s 2015 Equity and Incentive Compensation Plan (“2015 Plan”), which is administered by the Compensation Committee of the Company’s 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 the Company’s common stock that may be awarded under the 2015 Plan is 367,977.

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 dependable 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. Billings in excess of revenues earned on contracts in process are classified in Other accrued expenses in the Consolidated Balance Sheet and totaled $22.7 million and $16.8 million at December 31, 2016 and 2015, 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.

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 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 2016 and 2015, we sold approximately $81.6 million and $118.5 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 2016 and 2015, an expense in the amount of $0.5 million and $0.6 million, respectively, related to the discount on sale of accounts receivable is recorded in the Consolidated Statements of Income.

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, 2016, the Company had uncollateralized receivables with six customers in the automotive industry, each with several locations, aggregating $37.8 million, which represented approximately 19% of the Company’s trade accounts receivable. During 2016, sales to these customers amounted to approximately $276.9 million, which represented approximately 22% 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 shareholders’ 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: Warranty liabilities are primarily associated with the Company’s industrial equipment business unit and the fluid routing solutions business. 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,
	2016			2015			2014
	(In millions)
Balance at January 1,	$	6.1		$	6.9		$	5.4
Claims paid during the year	(3.7		)	(4.7		)	(2.9		)
Warranty expense	2.0			4.0			4.0
Acquired warranty liabilities	2.8			—			—
Other	(0.1		)	(0.1		)	0.4
Balance at December 31,	$	7.1		$	6.1		$	6.9

Weighted-Average Number of Shares Used in Computing Earnings Per Share: The following table sets forth the weighted-average number of shares used in the computation of earnings per share:



	Year Ended December 31,
	2016	2015	2014
	(In whole shares)
Weighted average basic shares outstanding	12,126,264	12,215,425	12,097,018
Plus dilutive impact of employee stock awards	148,188	167,526	279,058
Weighted average diluted shares outstanding	12,274,452	12,382,951	12,376,076

Outstanding stock options with exercise prices greater than the average price of the common shares are anti-dilutive and are not included in the computation of diluted earnings per share. For the year ended December 31, 2016 and 2015, the anti-dilutive shares were insignificant.

Accounting Pronouncements Adopted

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, “Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” The ASU requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the debt issuance costs will continue to be reported as interest expense. The Company adopted this ASU during the first quarter of 2016 and applied this standard retrospectively to 2015. The new guidance impacted only the presentation of the Company's financial position and did not affect the Company's results of operations or cash flows. Refer to Note 6 for the impact on our consolidated balance sheet at December 31, 2015.

In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent).” Under the new guidance, investments measured at net asset value (“NAV”), as a practical expedient for fair value, are excluded from the fair value hierarchy. Removing investments measured using the practical expedient from the fair value hierarchy is intended to eliminate the diversity in practice that currently exists with respect to the categorization of these investments. The new guidance was effective for the Company on January 1, 2016. The guidance impacted the presentation of certain pension related assets that use NAV as a practical expedient. See Note 11 for additional information.

Recent Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which was the result of a joint project by the FASB and International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and International Financial Reporting Standards. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The ASU will require either retrospective application to each prior reporting period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. The Company is in the process of analyzing the impact of ASU 2014-09, and the related ASUs, across all its businesses. This includes reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard. The Company expects to adopt the new standard using the modified retrospective approach, under which the cumulative effect of initially applying the new guidance is recognized as an adjustment to the opening balance of retained earnings upon adoption effective January 1, 2018. We are still evaluating the impact and an estimation of the impact cannot be made at this time.

In January 2016, the FASB issued ASU 2016-1, "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. The Company is currently evaluating the impact of adopting this guidance.

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 2016, the FASB issued 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 ASU is effective for fiscal years beginning with the first quarter of 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance.

In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” The objective of the ASU is to identify, evaluate, and improve areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to uses of the financial statements. The ASU is effective for fiscal years beginning with the first quarter of 2018, with early adoption permitted. 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

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.

The 2014 consolidated financial statements have not been retroactively adjusted as these measurement period adjustments did not have a material impact on such statements.

The 2014 increase relates to the acquisitions of Apollo, Autoform and Saet.

(1) Prior to the adoption of ASU 2015-03 in the first quarter of 2016, debt issuance costs of $4.5 million at December 31, 2015 were reflected in the consolidated balance sheet in Other long-term assets. Such amount was reclassified to Long-term debt for comparative purposes.

On December 21, 2016, the Company, through its subsidiary, Industrial Equipment Group European Holding Company Limited subsidiary, entered into a financing agreement with Banco Bolbao Vizcaya Argentaria, S.A. The financing agreement provides the Company the ability to borrow up to $36.9 million, including a loan for $26.4 million for the acquisition of GH as well as a revolving credit facility for up to $10.5 million to fund working capital and general corporate needs. The full amount of the loan is outstanding as of December 31, 2016; no amounts have been drawn on the revolving credit facility as of December 31, 2016.

In addition to the Agreement, the Company also assumed long-term debt of $8.9 million and short-term debt of $5.0 million as part of the GH acquisition.

On April 22, 2016, the Company further amended its credit facility (the “Amended Credit Agreement”) to:


•	increase the revolving credit facility to $300.0 million;


•	increases the inventory advance rate from 50% to 60%, reducing back to 50% on a pro-rata quarterly basis over 36 months commencing July 1, 2016;


•	reload the term loan up to $35.0 million, of which $23.4 million has been borrowed and is outstanding as of December 31, 2016;


•	increases the Canadian sub-limit up to $35.0 million;


•	increases the European sub-limit up to $25.0 million; and


•	provide minor pricing adjustments including pricing the first $35.0 million drawn on the revolver at LIBOR + 3.50%, reducing automatically on a pro-rata quarterly basis over 36 months commencing July 1, 2016.

Under the Amended Credit Agreement, a detailed borrowing base formula provides borrowing availability to the Company based on percentages of eligible accounts receivable and inventory.

At the Company’s election, domestic amounts borrowed under the revolving credit facility may be borrowed at either LIBOR plus 1.5% to 2.5%; or the bank’s prime lending rate minus 0.25% to 1.25%. The LIBOR-based interest rate is dependent on the Company’s debt service coverage ratio, as defined in the Amended Credit Agreement.

Amounts borrowed under the Canadian revolving credit facility provided by the Amended Credit Agreement may be borrowed at either the Canadian deposit offered rate plus 1.5% to 2.5%; the Canadian prime lending rate plus 0.0% to 1.0%; or the US base rate plus 0.0% to 1.0%.

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 agreement provides the Company the ability to borrow up to $11.0 million for expansion of its manufacturing facility in Arkansas. The loan matures in September 2025. The Company has borrowed $6.2 million under this agreement as of December 31, 2016.

On August 13, 2015, the Company entered into a capital lease agreement (the “Lease Agreement”). The Lease Agreement provides the Company up to $50.0 million for capital leases. See Note 10 for additional disclosure.

The term loan is amortized based on a seven-year schedule with the balance due at maturity (July 31, 2019). The Amended Credit Agreement also reduced the commitment fee for the revolving credit facility. At the Company's election, amounts borrowed under the term loan may be borrowed at either LIBOR plus 2.0% to 3.0%; or the bank’s prime lending rate minus 0.75% to plus 0.25%.

At December 31, 2016, the Company had approximately $106.2 million of unused borrowing capacity under the revolving credit facility.

The following table represents fair value information of the Company's senior notes due 2021 (the “Senior Notes”), classified as Level 1, at December 31, 2016 and 2015. The fair value was estimated using quoted market prices.

The Senior 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, 2016, the Company was in compliance with all financial covenants of the Credit Agreement.

At December 31, 2016, the Company has U.S., state and foreign net operating loss carryforwards for income tax purposes. The foreign net operating loss carryforward is $22.1 million, of which $5.5 million expires between 2017 and 2036 and the remainder has no expiration date. The Company has a tax benefit from a state net operating loss carryforward of $2.7 million that expires between 2017 and 2036. 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.

As of December 31, 2016 and 2015, 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. As of December 31, 2014, the Company reversed a valuation allowance of $1.3 million against its state net operating loss carryforward. As of December 31, 2016 and 2015, the Company recorded valuation allowances of $4.5 million and $4.2 million, respectively, against certain foreign net deferred tax assets. 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:



	2016			2015			2014
	(In millions)
Unrecognized Tax Benefit — January 1,	$	6.3		$	6.5		$	5.9
Gross Increases to Tax Positions Related to Prior Years	0.3			0.3			0.8

Expiration of Statute of Limitations	(3.7		)	(0.4		)	—
Unrecognized Tax Benefit — December 31,	$	2.9		$	6.3		$	6.5

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $2.4 million at December 31, 2016 and $5.5 million at December 31, 2015. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the year ended December 31, 2016 and 2015, the Company recognized approximately $(1.4) million and $0.2 million, respectively, in net interest and penalties. The Company had approximately $0.4 million and $1.9 million for the payment of interest and penalties accrued at December 31, 2016 and 2015, respectively. It is reasonably possible that within the next twelve months the amount of gross unrecognized tax benefits could be reduced by approximately $1.4 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 2013 through 2016 remain open for examination by the Internal Revenue Service and 2012 through 2016 remain open for examination by various state and foreign taxing authorities.

Deferred taxes have not been provided on approximately $131.1 million of undistributed earnings of the Company’s foreign subsidiaries as it is the Company’s policy and intent to permanently reinvest such earnings. The Company has determined that it is not practicable to determine the unrecognized tax liability on such undistributed earnings.

Commitments, Contingencies and Litigation Judgment	Dec. 31, 2016
Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Litigation Judgment	Commitments, Contingencies and Litigation Judgment 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 Park-Ohio Holdings Corporation, 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 million in damages plus an unspecified amount of punitive damages. ATM denied the allegations. ATM subsequently obtained summary judgment on the constructive fraud claim, which was dismissed by the district court prior to trial. The remaining claims were the subject of a bench trial that occurred in May 2013. After IPSCO presented its case, the district court entered partial judgment in favor of ATM, dismissing the gross negligence claim, a portion of the breach of contract claim, and any claim for punitive damages. The trial proceeded with respect to the remainder of IPSCO's claim for breach of contract. 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. IPSCO subsequently filed a motion seeking to recover $3.8 million in attorneys’ fees and costs. The district court reserved ruling on that issue pending an appeal. In October 2013, ATM filed an appeal with the U.S. Court of Appeals for the Eighth Circuit seeking reversal of the judgment in favor of IPSCO. In November 2013, IPSCO filed a cross-appeal seeking reversal of the dismissal of its claim for gross negligence and punitive damages. The Eighth Circuit issued an opinion in March 2015 affirming in part, reversing in part, and remanding the case. It affirmed the district court's determination that ATM was liable for breach of contract. It also affirmed the district court's dismissal of IPSCO's claim for gross negligence and punitive damages. However, the Eighth Circuit reversed nearly all of the damages awarded by the district court and remanded for further findings on the issue of damages, including whether consequential damages are barred under the express language of the contract. Because IPSCO did not appeal the award of $5.2 million in its favor, those damages could be decreased, but could not be increased, on remand. On remand, the district court entered an order once again awarding IPSCO $5.2 million In December 2015, ATM filed a second appeal with the Eighth Circuit seeking reversal of the damages award. That appeal is pending. 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. As of December 31, 2016, the Company had $7.4 million accrued for this matter. In August 2013, we received a subpoena from the staff of the SEC in connection with the staff’s investigation of a third party. At that time, we also learned that the Department of Justice (“DOJ”) is conducting a criminal investigation of the third party. In connection with its initial response to the staff’s subpoena, we disclosed to the staff of the SEC that, in November 2007, the third party participated in a payment on behalf of us to a foreign tax official that implicates the Foreign Corrupt Practices Act. The Board of Directors formed a special committee to review our transactions with the third party and to make any recommendations to the 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.

Compensation and Retirement Disclosure [Abstract]

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, 2016 and 2015:

In determining its expected return on plan assets assumption for the year ended December 31, 2016, the Company considered historical experience, its asset allocation, expected future long-term rates of return for each major asset class, and an assumed long-term inflation rate. This assumption was supported by the asset return generation model, which projected future asset returns using simulation and asset class correlation.

Effective December 31, 2015, the Company adopted a change in the method used to estimate the service and interest cost components of net periodic benefit cost for its defined benefit pension plans. Historically, the service and interest cost components were estimated using a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. For 2016, 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, resulting in a more precise measurement. These spot rates were determined as of the measurement date of December 31, 2015. This change does not affect the measurement of total benefit obligations. The change was accounted for as a change in estimate and, accordingly, was accounted for prospectively starting in 2016. The spot rates used to determine service and interest costs ranged from 3.29% to 4.19% for the U.S. pension plan. The reductions in service and interest costs for 2016 associated with this change were $0.1 million and $0.5 million, respectively.

Similar to the changes in the discount rate approach discussed for the pension plans above, effective December 31, 2015, we elected to use an approach that discounts the individual expected cash flows underlying interest and service costs using the applicable spot rates derived from the yield curve used to determine the benefit obligation to the relevant projected cash flows. The spot rates used to determine service and interest costs ranged from 2.93% to 4.43% for the postretirement benefit plans. The reductions in service and interest costs in 2016 associated with this change were $0.0 million and $0.1 million, respectively.

Total recognized in accumulated other comprehensive loss at end of year	$	26.1		$	25.5		$	15.7		$	1.5		$	4.1		$	7.2

The estimated net loss, prior service cost and net transition obligation for the defined benefit pension plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the year ending December 31, 2017 is $1.1 million.

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, 2017 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)
2017	$	4.7	$	1.3	$	0.2	$	1.1
2018	4.4		1.2		0.2		1.0
2019	4.3		1.1		0.1		1.0
2020	4.5		1.0		0.1		0.9
2021	4.6		0.9		0.1		0.8
2022 to 2026	23.4		4.0		0.5		3.5

The Company has a postretirement benefit plan. Under the 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 2016	$	—	$	—
Effect on postretirement benefit obligation as of December 31, 2016	$	0.7	$	(0.6	)

The Company expects to make no contributions to its defined benefit plans in 2017.

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 2016, and expense of $0.6 million in 2015 and $0.5 million in 2014 related to the SERP.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2016
Accounting Policies [Abstract]
Consolidation and Basis of Presentation	Consolidation and Basis of Presentation: Park-Ohio Holdings Corp. (“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.
Inventories	Inventories: Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or market 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).
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets: We assess the recoverability of long-lived assets (excluding goodwill) and identifiable acquired intangible assets with finite useful lives whenever impairment indicators exist. When impairment indicators exist, we measure the recoverability of assets to be held and used by a comparison of the carrying amount of the asset to the expected net future undiscounted cash flows to be generated by that asset. The amount of impairment of identifiable intangible assets with finite useful lives, if any, to be recognized is measured based on projected discounted future cash flows. We measure the amount of impairment of other long-lived assets (excluding goodwill) as the amount by which the carrying value of the asset exceeds the fair value of the asset, which is generally determined, based on projected discounted future cash flows or appraised values.
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 mode based on forecasted cash flows and weighted average cost of capital, and other valuation techniques to determine fair 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, 2016 and December 31, 2015 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 2016, 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. Under the provisions of the Company’s 2015 Equity and Incentive Compensation Plan (“2015 Plan”), which is administered by the Compensation Committee of the Company’s 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 the Company’s common stock that may be awarded under the 2015 Plan is 367,977.
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 dependable 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. Billings in excess of revenues earned on contracts in process are classified in Other accrued expenses in the Consolidated Balance Sheet and totaled $22.7 million and $16.8 million at December 31, 2016 and 2015, respectively.
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.
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 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 2016 and 2015, we sold approximately $81.6 million and $118.5 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.
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 shareholders’ 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	Warranties: Warranty liabilities are primarily associated with the Company’s industrial equipment business unit and the fluid routing solutions business. 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.
Earnings Per Share	Outstanding stock options with exercise prices greater than the average price of the common shares are anti-dilutive and are not included in the computation of diluted earnings per share. For the year ended December 31, 2016 and 2015, the anti-dilutive shares were insignificant.
Accounting Pronouncements Adopted	Accounting Pronouncements Adopted In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, “Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” The ASU requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the debt issuance costs will continue to be reported as interest expense. The Company adopted this ASU during the first quarter of 2016 and applied this standard retrospectively to 2015. The new guidance impacted only the presentation of the Company's financial position and did not affect the Company's results of operations or cash flows. Refer to Note 6 for the impact on our consolidated balance sheet at December 31, 2015. In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent).” Under the new guidance, investments measured at net asset value (“NAV”), as a practical expedient for fair value, are excluded from the fair value hierarchy. Removing investments measured using the practical expedient from the fair value hierarchy is intended to eliminate the diversity in practice that currently exists with respect to the categorization of these investments. The new guidance was effective for the Company on January 1, 2016. The guidance impacted the presentation of certain pension related assets that use NAV as a practical expedient. See Note 11 for additional information. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which was the result of a joint project by the FASB and International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and International Financial Reporting Standards. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The ASU will require either retrospective application to each prior reporting period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. The Company is in the process of analyzing the impact of ASU 2014-09, and the related ASUs, across all its businesses. This includes reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard. The Company expects to adopt the new standard using the modified retrospective approach, under which the cumulative effect of initially applying the new guidance is recognized as an adjustment to the opening balance of retained earnings upon adoption effective January 1, 2018. We are still evaluating the impact and an estimation of the impact cannot be made at this time. In January 2016, the FASB issued ASU 2016-1, "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. The Company is currently evaluating the impact of adopting this guidance. 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 2016, the FASB issued 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 ASU is effective for fiscal years beginning with the first quarter of 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance. In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” The objective of the ASU is to identify, evaluate, and improve areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to uses of the financial statements. The ASU is effective for fiscal years beginning with the first quarter of 2018, with early adoption permitted. 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.
Commitments, Contingencies and Litigation Judgment	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.
