Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: The Corporation’s accounting policies conform to accounting principles generally accepted in the United States of America. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to estimates and assumptions include valuing the assets and obligations related to employee benefit plans, assessing the carrying value of long-lived assets, accounting for loss contingencies associated with claims and lawsuits and accounting for income taxes. Actual results could differ from those estimates. A summary of the significant accounting policies followed by the Corporation is presented below. Certain amounts for the preceding periods have been reclassified for comparative purposes. Consolidation All subsidiaries are wholly owned and are included in the consolidated financial statements of the Corporation. Intercompany accounts and transactions are eliminated. Investments in joint ventures where the Corporation owns 20% to 50% of the voting stock and has the ability to exercise significant influence over the operating and financial policies of the joint venture are accounted for using the equity method of accounting. Investments in joint ventures whereby the Corporation does not have the ability to exercise significant influence over the operating and financial policies of the joint venture are accounted for using the cost method of accounting. Investments in joint ventures are reviewed for impairment whenever events or circumstances indicate the carrying amount of the investment may not be recoverable. If the estimated fair value of the investment is less than the carrying amount and such decline is determined to be “other than temporary,” then the investment may not be fully recoverable potentially resulting in a write-down of the investment value. Cash and Cash Equivalents Securities with purchased original maturities of three months or less are considered to be cash equivalents. The Corporation maintains cash and cash equivalents at various financial institutions which may exceed federally insured amounts. Inventories Inventories are valued at the lower of cost or market. Cost includes the cost of raw materials, direct labor and overhead for those items manufactured but not yet sold or for which title has not yet transferred. Fixed production overhead is allocated to inventories based on normal capacity of the production facilities. In periods of abnormally high production, the amount of fixed overhead allocated to each unit of production is decreased so that inventories are not measured above cost. The amount of fixed overhead allocated to inventories is not increased as a consequence of abnormally low production or idle plant. Costs for abnormal amounts of spoilage, handling costs and freight costs are charged to expense when incurred. Cost of domestic raw materials, work-in-process and finished goods inventories is primarily determined by the last-in, first-out (LIFO) method. Cost of domestic supplies and foreign inventories is determined primarily by the first-in, first-out (FIFO) method. Property, Plant and Equipment Property, plant and equipment are recorded at cost with depreciation computed using the straight-line method over the following estimated useful lives: land improvements – 15 to 20 years, buildings – 25 to 50 years and machinery and equipment – 3 to 25 years. Expenditures that extend economic useful lives are capitalized. Routine maintenance is charged to expense. Gains or losses are recognized on retirements or disposals. Property, plant and equipment are reviewed for impairment whenever events or circumstances indicate the carrying amount of the asset may not be recoverable. If the undiscounted cash flows generated from the use and eventual disposition of the assets are less than their carrying value, then the asset value may not be fully recoverable potentially resulting in a write-down of the asset value. Estimates of future cash flows are based on expected market conditions over the remaining useful life of the primary asset(s). Proceeds from government grants are recorded as a reduction in the purchase price of the underlying assets and amortized against depreciation over the lives of the related assets. Product Warranty Provisions for product warranties are recognized at the time the underlying sale is recorded. The provision is based on historical experience as a percentage of sales adjusted for potential claims when a liability is probable and for known claims. Employee Benefit Plans Funded Status If the fair value of the plan assets exceeds the projected benefit obligation, the over-funded projected benefit obligation is recognized as an asset (prepaid pensions) on the consolidated balance sheet. Conversely, if the projected benefit obligation exceeds the fair value of the plan assets, the under-funded projected benefit obligation is recognized as a liability (employee benefit obligations) on the consolidated balance sheet. Gains and losses arising from the difference between actuarial assumptions and actual experience and unamortized prior service costs are recorded as a separate component of accumulated other comprehensive loss and presented net of income tax. Net Periodic Pension and Other Postretirement Costs Net periodic pension and other postretirement costs includes service cost, interest cost, expected rate of return on the market-related value of plan assets, amortization of prior service costs and recognized actuarial gains or losses. When actuarial gains or losses exceed 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are amortized to net periodic pension and other postretirement costs over the average remaining service period of employees expected to receive benefits under the plan. When the actuarial gains or losses are less than 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are included in net periodic pension and other postretirement costs indirectly as a result of lower/higher interest costs arising from a decrease/increase in the projected benefit obligation. The market-related value of plan assets is determined using a five-year moving average which recognizes 20% of unrealized gains and losses each year. Other Comprehensive Income (Loss) Other comprehensive income (loss) includes changes in assets and liabilities from non-owner sources including foreign currency translation adjustments, unamortized prior service costs and unrecognized actuarial gains and losses associated with employee benefit plans, unrealized holding gains and losses on securities designated as available for sale and changes in the fair value of derivatives designated and effective as cash flow hedges. Certain components of other comprehensive income (loss) are presented net of income tax. Foreign currency translation adjustments exclude the effect of income tax since earnings of non-U.S. subsidiaries are deemed to be reinvested for an indefinite period of time. Reclassification adjustments are amounts which are realized during the year and, accordingly, are deducted from other comprehensive income (loss) in the period in which they are included in net income (loss) or when a transaction no longer qualifies as a cash flow hedge. Foreign currency translation adjustments are included in net income (loss) upon sale or upon complete or substantially complete liquidation of an investment in a foreign entity. With respect to employee benefit plans, unamortized prior service costs are included in net income (loss) either immediately upon curtailment of the employee benefit plan or over the average remaining service period of employees expected to receive benefits and unrecognized actuarial gains and losses are included in net income (loss) indirectly as a result of lower/higher interest costs arising from a decrease/increase in the projected benefit obligation. Unrealized holding gains and losses on securities are included in net income (loss) when the underlying security is sold. Changes in the fair value of derivatives are included in net income (loss) when the projected sale occurs or, if a foreign currency purchase contract, over the estimated useful life of the underlying asset. Revenue Recognition Revenue from sales is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Persuasive evidence of an arrangement identifies the final understanding between the parties as to the specific nature and terms of the agreed-upon transaction that creates enforceable obligations. It can be in the form of an executed purchase order from the customer, sales agreement issued by the Corporation or a similar arrangement deemed to be normal and customary business practice for that particular customer or class of customer (collectively, a sales agreement). Delivery and performance is considered to have occurred when the customer has taken title and assumed the risks and rewards of ownership of the product. Typically this occurs when the product is shipped to the customer (i.e., FOB shipping point), delivered to the customer (i.e., FOB destination), or, for foreign sales, in accordance with trading guidelines known as Incoterms. Incoterms are standard trade definitions used in international contracts and are developed, maintained and promoted by the ICC Commission on Commercial Law and Practice. The sales price required to be paid by the customer is fixed or determinable from the sales agreement. It is not subject to refund or adjustment except for a variable-index surcharge provision which increases or decreases, as applicable, the selling price of a rolling mill roll for corresponding changes in the published index cost of certain raw materials. The variable-index surcharge is recognized as revenue when the corresponding revenue for the inventory is recognized. Likelihood of collectability is assessed prior to acceptance of an order. There are no customer-acceptance provisions other than customer inspection and testing prior to shipment. Post-shipment obligations are insignificant. Amounts billed to the customer for shipping and handling are recorded within net sales and the related costs are recorded within costs of products sold (excluding depreciation). Amounts billed for taxes assessed by various government authorities (e.g. sales tax, value-added tax, etc.) are excluded from the determination of net income and instead are recorded as a liability until remitted to the government authority. Foreign Currency Translation Assets and liabilities of the Corporation’s foreign operations are translated at year-end exchange rates and the statements of operations are translated at the average exchange rates for the year. Gains or losses resulting from translating foreign currency financial statements are accumulated as a separate component of accumulated other comprehensive loss until the entity is sold or substantially liquidated. Derivative Instruments Derivative instruments which include forward exchange (for foreign currency sales and purchases) and futures contracts are recorded on the consolidated balance sheet as either an asset or a liability measured at their fair value. The accounting for changes in the fair value of a derivative depends on the use of the derivative. To the extent that a derivative is designated and effective as a cash flow hedge of an exposure to future changes in value, the change in the fair value of the derivative is deferred in accumulated other comprehensive loss. Any portion considered to be ineffective, including that arising from the unlikelihood of an anticipated transaction to occur, is reported as a component of earnings (other income/expense) immediately. Upon occurrence of the anticipated sale, the foreign currency sales contract designated and effective as a cash flow hedge is de-designated as a fair value hedge and the change in fair value previously deferred in accumulated other comprehensive loss is reclassified to earnings (net sales) with subsequent changes in fair value recorded as a component of earnings (other income/expense). Upon occurrence of the anticipated purchase, the foreign currency purchase contract is settled and the change in fair value deferred in accumulated other comprehensive loss is reclassified to earnings (depreciation expense) over the life of the underlying assets. Upon settlement of a futures contract, the change in fair value deferred in accumulated other comprehensive loss is reclassified to earnings (costs of products sold, excluding depreciation) when the corresponding inventory is sold and revenue is recognized. To the extent that a derivative is designated and effective as a hedge of an exposure to changes in fair value, the change in the derivative’s fair value will be offset in the statement of operations by the change in the fair value of the item being hedged and is recorded as a component of earnings (other income/expense). Cash flows associated with the derivative instruments are recorded as a component of operating activities on the consolidated statement of cash flows. The Corporation does not enter into derivative transactions for speculative purposes and, therefore, holds no derivative instruments for trading purposes. Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. A hierarchy of inputs is used to determine fair value measurements with three levels. Level 1 inputs are quoted prices in active markets for identical assets or liabilities and are considered the most reliable evidence of fair value. Level 2 inputs are observable prices that are not quoted on active exchanges. Level 3 inputs are unobservable inputs used for measuring the fair value of assets or liabilities. Legal Costs Legal costs expected to be incurred in connection with loss contingencies are accrued when such costs are probable and estimable. Income Taxes Income taxes are recognized during the year in which transactions enter into the determination of financial statement income. Deferred income tax assets and liabilities are recognized for the future tax consequences of temporary differences between the book carrying amount and the tax basis of assets and liabilities including net operating loss carryforwards. Unremitted earnings of the Corporation’s non-U.S. subsidiaries and affiliates are deemed to be permanently reinvested and, accordingly, no deferred income tax liability is recorded. A valuation allowance is provided against a deferred income tax asset when it is “more likely than not” the asset will not be realized. Similarly, if a determination is made that it is “more likely than not” the deferred income tax asset will be realized, the related valuation allowance would be reduced and a benefit to earnings would be recorded. Penalties and interest are recognized as a component of the income tax provision. Tax benefits are recognized in the financial statements for tax positions taken or expected to be taken in a tax return when it is “more likely than not” that the tax authorities will sustain the tax position solely on the basis of the position’s technical merits. Consideration is given primarily to legislation and statutes, legislative intent, regulations, rulings and case law as well as their applicability to the facts and circumstances of the tax position when assessing the sustainability of the tax position. In the event a tax position no longer meets the “more likely than not” criteria, the tax benefit is reversed by recognizing a liability and recording a charge to earnings. Conversely, if a tax position subsequently meets the “more likely than not” criteria, a tax benefit would be recognized by reducing the liability and recording a credit to earnings. Earnings Per Common Share Basic earnings per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. The computation of diluted earnings per common share is similar to basic earnings per common share except that the denominator is increased to include the dilutive effect of the net additional common shares that would have been outstanding assuming exercise of outstanding stock awards, calculated using the treasury stock method. The computation of diluted earnings per share would not assume the exercise of an outstanding stock award if the effect on earnings per common share would be antidilutive. Similarly, the computation of diluted earnings per share would not assume the exercise of outstanding stock awards if the Corporation incurred a net loss since the effect on earnings per common share would be antidilutive. The weighted average number of common shares outstanding assuming exercise of dilutive stock awards was 10,447,066 for 2015, 10,404,744 for 2014 and 10,406,478 for 2013. Weighted-average outstanding stock awards excluded from the diluted earnings per common share calculation, since the effect would have been antidilutive, were 1,138,287 for 2015, 1,242,545 for 2014 and 781,325 for 2013.

Investments in Joint Ventures	NOTE 2 – INVESTMENTS IN JOINT VENTURES: In 2007, a subsidiary of UES entered into an agreement with Maanshan Iron & Steel Company Limited (Maanshan) to form a joint venture company in China. UES owns 49% of the joint venture company and Maanshan owns 51%. Both companies contributed cash for their respective interests (which equated to $14,700 for UES). The joint venture company principally manufactures and sells forged backup rolling mill rolls of a size and weight currently not able to be produced by UES. A significant portion of its sales have been to Maanshan or entities controlled by Maanshan. Additionally, the majority of its raw materials is purchased from Maanshan or entities controlled by Maanshan. UES has not guaranteed any of the obligations of the joint venture; accordingly, its maximum exposure of loss is limited to its investment. Since UES is the minority shareholder and allocation of earnings and voting rights is proportional to ownership interests, UES is not considered the primary beneficiary and, accordingly, accounts for its 49% interest in the joint venture under the equity method of accounting. Losses of the joint venture approximated $(1,050), $(2,165) and $(4,203) for the twelve month period ended September 30, 2015, 2014 and 2013, respectively, of which the Corporation has recognized its share (49%) in its consolidated statements of operations. The joint venture has been adversely impacted by the global economy, with significantly depressed pricing, reduced demand and excess roll inventories of its potential customer base in China – all hindering profitability. Losses have been incurred since 2009, in which we have recognized our share (49%) in our consolidated statements of operations, and are expected to continue through 2016 and into 2017. In the fourth quarter of 2013, the Corporation, with the help of outside consultants and appraisers, concluded that the estimated fair value of its investment was less than its carrying amount and that the decline was “other than temporary.” Accordingly, the Corporation recognized an impairment charge of $6,407 reducing the carrying amount of its investment to $3,670. The carrying amount of the investment at December 31, 2015 is $1,757. The overall financial strength of the joint venture remains weak with a significant reliance on the 51% partner or entities controlled by the 51% partner to provide financing and working capital. The Corporation will continue to monitor the carrying value of the investment to determine if additional impairment charges are necessary. Assets, liabilities and shareholders’ equity of the joint venture as of September 30, 2015 and 2014 are summarized below. The differences between the carrying amount of the investment and the value of the underlying equity in the net assets of the joint venture relates primarily to the impairment charge recognized in 2013 and elimination of 49% of the profit (“intercompany profit”) on the sale of technology from UES to the joint venture in earlier years which will be recognized when realized outside of the controlled group. 2015 2014 Assets: Current assets (includes receivables from related parties of $935 and $524, respectively) $ 8,332 $ 10,743 Noncurrent assets 28,993 32,948 $ 37,325 $ 43,691 Liabilities and Shareholders’ Equity: Current liabilities (include liabilities to related parties of $17,230 and $22,039, respectively) $ 17,455 $ 22,156 Shareholders’ equity 19,870 21,535 $ 37,325 $ 43,691 The Corporation also has a 25% investment in a Chinese cast roll joint venture company which is recorded at cost, or $1,340. The Corporation does not participate in the management or daily operation of the joint venture company, has not guaranteed any of its obligations and has no ongoing responsibilities to it. Dividends may be declared by the Board of Directors of the joint venture company after allocation of after-tax profits to various “funds” equal to the minimum amount required under Chinese law. No dividends were declared or received in 2015, 2014 or 2013.

The LIFO reserve approximated $(24,647) and $(23,299) at December 31, 2015 and 2014, respectively. During each of the years, inventory quantities decreased for various locations resulting in a liquidation of LIFO layers which were at lower costs. The effect of the liquidations was to decrease costs of products sold (excluding depreciation) by approximately $216, $2,196 and $1,803 for 2015, 2014 and 2013, respectively, which increased net income by approximately $141 or $0.01 per common share for 2015 and $1,172 or $0.11 per common share for 2013 and reduced net loss by approximately $1,427 or $0.14 per common share for 2014.

Debt Disclosure [Abstract]
Borrowing Arrangements	NOTE 6 – BORROWING ARRANGEMENTS: The Corporation maintains short-term lines of credit of approximately $8,100 (including £2,500 in the United Kingdom and €400 in Belgium). No amounts were outstanding under these lines of credit as of December 31, 2015 and 2014. As of December 31, 2015, the Corporation had the following Industrial Revenue Bonds (IRBs) outstanding: (1) $4,120 tax-exempt IRB maturing in 2020, interest at a floating rate which averaged 0.08% during the current year; (2) $7,116 taxable IRB maturing in 2027, interest at a floating rate which averaged 0.18% during the current year; and (3) $2,075 tax-exempt IRB maturing in 2029, interest at a floating rate which averaged 0.10% during the current year. The IRBs are remarketed periodically at which time interest rates are reset. The IRBs are secured by letters of credit of equivalent amounts. The letter of credit agreements require, among other things, maintenance of a minimum net worth and prohibit a leverage ratio in excess of a stipulated amount. The Corporation was in compliance with the applicable bank covenants as of December 31, 2015. Despite principal not beginning to become due until 2020, the IRBs can be put back to the Corporation on short notice if, although considered remote by the Corporation and its bankers, the bonds cannot be remarketed. At that time, the bondholders can seek reimbursement from the letters of credit. As provided by a separate agreement with the Corporation’s bank, funding of the letters of credit, if so drawn against, would be satisfied with equal and immediate borrowings under a separate IRB Standby Letter of Credit facility (the “Facility”). The Facility expires on August 1, 2017 and is expected to be renewed annually to provide for a continual term of greater than one year. However, the Facility includes language regarding “material adverse change” to the Corporation’s business which could result in it being called or cancelled at the bank’s discretion; accordingly, the IRBs remain classified as a current liability. The availability under the Facility is $13,566, equal to the letters of credit, and as of December 31, 2015 no amounts were outstanding.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits	NOTE 7 – PENSION AND OTHER POSTRETIREMENT BENEFITS: Pension Plans The Corporation has a qualified defined benefit pension plan covering substantially all of its U.S. employees. Effective July 1, 2015, the plan was amended to freeze benefit accruals and participation in the plan for non-union hourly and salaried participants and, effective January 1, 2016, for employees of the Union Electric Steel Carnegie Steelworkers Location, and replace it with employer contributions of a 3% base contribution and a matching contribution of up to 4% to the defined contribution plan. For 2015, employer contributions to the defined contribution plan totaled $882 and are expected to approximate $1,892 in 2016. The plan changes resulted in a remeasurement of the plan liability, reducing the liability by approximately $10,306, and curtailment losses of $1,303. Additionally, during 2015, the plan was amended to permit lump sum distributions to deferred vested participants and deferred beneficiaries who were not offered a lump sum in 2014. The defined benefit pension plan is covered by the Employee Retirement Income Security Act of 1974 (“ERISA”); accordingly, the Corporation’s policy is to fund at least the minimum actuarially computed annual contribution required under ERISA. Although no minimum contributions were required for any of the three years, voluntary contributions of $5,000 were made in 2013. Additionally, due to voluntary contributions and relief provided by Moving Ahead for Progress in the 21st Century Highway and Transportation Funding Act of 2014 Employees of UES-UK participate in a defined benefit pension plan that was curtailed effective December 31, 2004 and replaced with a defined contribution pension plan. The UES-UK plans are non-U.S. plans and therefore are not covered by ERISA. Instead, the Trustees and UES-UK have agreed to a recovery plan that estimates the amount of employer contributions at £1,123 annually through October 2021, based on U.K. regulations, necessary to eliminate the funding deficit of the plan with such estimates subject to change based on the future investment performance of the plan’s assets. The U.S. dollar equivalent of employer contributions to the defined benefit pension plan approximated $1,715, $1,849 and $1,764 in 2015, 2014 and 2013, respectively, and are expected to approximate $1,662 in 2016. The fair value of the plan’s assets as of December 31, 2015 and 2014 approximated $49,628 (£33,528) and $50,533 (£32,437), respectively, in comparison to accumulated benefit obligations of $63,750 (£43,069) and $70,523 (£45,268) for the same periods. Estimated benefit payments for subsequent years are $1,434 for 2016, $2,116 for 2017, $1,548 for 2018, $2,503 for 2019, $2,837 for 2020 and $13,894 for 2021 – 2025. Contributions to the defined contribution pension plan approximated $382, $407 and $316 in 2015, 2014 and 2013, respectively, and are expected to approximate $315 in 2016. The Corporation also maintains nonqualified defined benefit pension plans for selected executives in addition to the benefits provided under the Corporation’s qualified defined benefit pension plan. The objectives of the nonqualified plans are to provide supplemental retirement benefits or restore benefits lost due to limitations set by the Internal Revenue Service. The assets of the nonqualified plans are held in a grantor tax trust known as a “Rabbi” trust and are subject to claims of the Corporation’s creditors, but otherwise must be used only for purposes of providing benefits under the plans. No contributions were made to the trust in 2013 – 2015 and none are expected in 2016. The fair market value of the trust at December 31, 2015 and 2014, which is included in other noncurrent assets, was $3,663 and $4,280, respectively. Changes in the fair market value of the trust are recorded as a component of other comprehensive income (loss). The plan is treated as a non-funded pension plan for financial reporting purposes. Accumulated benefit obligations approximated $5,676 and $4,294 at December 31, 2015 and 2014, respectively. Estimated benefit payments for subsequent years, which would represent employer contributions, are approximately $360 for 2016, $387 for 2017, $414 for 2018, $433 for 2019, $461 for 2020 and $2,516 for 2021 – 2025. Employees at one location participate in a multi-employer plan, I.A.M. National Pension Fund, I.A.M. National Pension Fund • More than 1,750 employer locations contribute to the plan • Approximately 275,000 employees participate in the plan • Assets of approximately $10.9 billion and a funded status in excess of 100%. Less than 100 of the Corporation’s employees participate in the plan and contributions are based on a rate per hour. The Corporation’s contributions to the plan equaled $236, $233 and $230 in 2015, 2014 and 2013, respectively, and represent less than five percent of total contributions to the plan by all contributing employers. Contributions are expected to approximate $284 in 2016. Other Postretirement Benefits The Corporation provides postretirement health care benefits principally to the bargaining groups of one subsidiary. The plan covers participants and their spouses and/or dependents who retire under the existing pension plan on other than a deferred vested basis and at the time of retirement have also rendered 15 or more years of continuous service irrespective of age. During 2014, effective January 1, 2015, the plan was modified and existing coverage for the bargaining groups was replaced with monthly reimbursements. The plan change resulted in a remeasurement of the plan liability as of May 1, 2014, reducing the liability by approximately $8,914. Additionally, during 2015, the plan was further amended to provide monthly reimbursement for a 5-year period, which further reduced the plan liability by approximately $4,437. Retiree life insurance continues to be provided to substantially all retirees. The Corporation also provides health care and life insurance benefits to former employees of certain discontinued operations. This obligation had been estimated and provided for at the time of disposal. The Corporation’s postretirement health care and life insurance plans are not funded or subject to any minimum regulatory funding requirements. Estimated benefit payments for subsequent years, which would represent employer contributions, are approximately $624 for 2016, $635 for 2017, $659 for 2018, $672 for 2019, $687 for 2020, and $3,058 for 2021 – 2025.

Pension assets are invested with the objective of maximizing long-term returns while minimizing material losses to meet future benefit obligations as they become due. Investments in equity securities are primarily in common stocks of publicly-traded U.S. and international companies across a broad spectrum of industry sectors. Investments in fixed-income securities are principally A-rated or better bonds with maturities of less than ten years, preferred stocks and convertible bonds. The Corporation believes there are no significant concentrations of risk associated with the Plans’ assets. Attempts to minimize risk include allowing temporary changes to the allocation mix in response to market conditions, diversifying investments among asset categories (e.g., equity securities, fixed-income securities, alternative investments, cash and cash equivalents) and within these asset categories (e.g., economic sector, industry, geographic distribution, size) and consulting with independent financial and legal counsels to assure that the investments and their expected returns and risks are consistent with the goals of the Board of Directors or Trustees. With respect to the U.S. pension plan, the following investments are prohibited unless otherwise approved by the Board of Directors: stock of the Corporation, futures and options except for hedging purposes, unregistered or restricted stock, warrants, margin trading, short-selling, real estate excluding public or real estate partnerships, and commodities including art, jewelry and gold. The foreign pension plan invests in specific funds. Any investments other than those specifically identified would be considered prohibited. The following summarizes target asset allocations (within +/-5% considered acceptable) and major asset categories. Certain investments are classified differently for target asset allocation purposes and external reporting purposes.

Similarly, corporate debt and preferred securities consist of fixed-income securities of U.S. and U.K. corporations and price quotes for these investments are readily available. Common collective trust and commingled funds are not traded publicly, but the underlying assets (such as stocks and bonds) held in these funds are traded on active markets and the prices for the underlying assets are readily observable. For securities not actively traded, the fair value may be based on third-party appraisals, discounted cash flow analysis, benchmark yields and inputs that are currently observable in markets for similar securities. Investment Strategies The significant investment strategies of the various funds are summarized below. Fund Investment Strategy Primary Investment Objective Temporary Investment Funds Invests primarily in a diversified portfolio of investment grade money market instruments. Achieve a market level of current income while maintaining stability of principal and liquidity. Various Equity Funds Each fund maintains a diversified holding in common stock of applicable companies (e.g. common stock of small capitalization companies if a small-cap fund, common stock of medium capitalization companies if a mid-cap fund, common stock of foreign corporations if an international fund, etc.).

In determining net periodic pension costs, the expected long-term rate of return on the market-related value of plan assets is used. Differences between the actual return on plan assets and the expected long-term rate of return on plan assets are classified as part of unrecognized actuarial gains or losses and are recorded as a component of accumulated other comprehensive loss on the consolidated balance sheet. When these gains or losses exceed 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are amortized to net periodic pension and other postretirement costs over the average remaining service period of employees expected to receive benefits under the plans. When the gains or losses are less than 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are included in net periodic pension and other postretirement costs indirectly as a result of lower/higher interest costs arising from a decrease/increase in the projected benefit obligation. Net periodic pension and other postretirement benefit costs include the following components for the year ended December 31: U.S. Pension Foreign Pension Other Postretirement 2015 2014 2013 2015 2014 2013 2015 2014 2013 Service cost $ 2,743 $ 3,683 $ 4,424 $ 0 $ 0 $ 0 $ 384 $ 505 $ 943 Interest cost 7,990 8,762 8,070 2,394 2,695 2,551 474 688 926 Expected return on plan assets (10,996 ) (10,747 ) (9,368 ) (2,681 ) (3,157 ) (2,485 ) 0 0 0 Amortization of prior service cost (credit) 371 854 640 0 0 0 (672 ) (441 ) 85 Amortization of actuarial loss 5,440 4,183 7,146 845 599 687 26 104 241 Curtailment loss 1,303 0 0 0 0 0 0 0 0 Net cost $ 6,851 $ 6,735 $ 10,912 $ 558 $ 137 $ 753 $ 212 $ 856 $ 2,195 Assumptions Assumptions are reviewed on an annual basis. The expected long-term rate of return on plan assets is an estimate of average rates of earnings expected to be earned on funds invested or to be invested to provide for the benefits included in the projected benefit obligation. Since these benefits will be paid over many years, the expected long-term rate of return is reflective of current investment returns and investment returns over a longer period. Consideration is also given to target and actual asset allocations, inflation and real risk-free return. The discount rates used in determining future pension obligations and other postretirement benefits for each of the plans are based on rates of return on high-quality fixed-income investments currently available and expected to be available during the period to maturity of the pension and other postretirement benefits. High-quality fixed-income investments are defined as those investments which have received one of the two highest ratings given by a recognized rating agency with maturities of 10+ years. The discount rates and weighted-average wage increases used to determine the benefit obligations as of December 31, 2015 and 2014 are summarized below. The change in discounts rates decreased plan benefit obligations and increased the funded status of the plans by approximately $11,000 as of December 31, 2015 in comparison to December 31, 2014. U.S. Pension Foreign Pension Other Postretirement 2015 2014 2015 2014 2015 2014 Discount rate 4.40 % 4.10 % 3.65 % 3.50 % 4.20 % 4.00 % Wage increases 3.00 % 4.00 % n/a n/a n/a n/a In addition, the assumed health care cost trend rate at December 31, 2015 for other postretirement benefits is 6% for 2016 gradually decreasing to 4.75% in 2019. In selecting rates for current and long-term health care assumptions, the Corporation considers known health care cost increases, the design of the benefit programs, the demographics of its active and retiree populations and expectations of inflation rates in the future. A one percentage point increase or decrease in the assumed health care cost trend rate would result in an inconsequential change to the postretirement benefit obligation at December 31, 2015 and the annual benefit expense for 2015. The following assumptions were used to determine net periodic pension and other postretirement benefit costs for the year ended December 31: U.S. Pension Foreign Pension Other Postretirement 2015 2014 2013 2015 2014 2013 2015 2014 2013 Discount rate 4.00/4.10 % 5.00 % 4.25% 3.50 % 4.50 % 4.50 % 4.00 % 5.00 % 4.25 % Expected long-term rate of return 8.00 % 8.00 % 8.00% 5.40 % 6.50 % 6.09 % n/a n/a n/a Wages increases 4.00 % 4.00 % 4.00% n/a n/a n/a n/a n/a n/a

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	NOTE 9 – STOCK-BASED COMPENSATION: In May 2011, the shareholders of the Corporation approved the adoption of the 2011 Omnibus Incentive Plan (“Incentive Plan”) which authorizes the issuance of up to 1,000,000 shares of the Corporation’s common stock for grants of equity-based compensation. Awards under the Incentive Plan may include incentive non-qualified stock options, stock appreciation rights, restricted shares and restricted stock units, performance awards, other stock-based awards or short-term cash incentive awards. Unexercised portions of terminated or forfeited awards are available for new awards. The Incentive Plan is administered by the Compensation Committee of the Board of Directors who has the authority to determine, within the limits of the express provisions of the Incentive Plan, the individuals to whom the awards will be granted; the nature, amount and terms of such awards; and the objectives and conditions for earning such awards. The Incentive Plan also provides for annual grants of shares of the Corporation’s common stock to non-employee directors following the Corporation’s annual shareholder meeting. Each annual director award will be for a number of shares having a fair market value equal to $25 and will fully vest as of the grant date. The number of shares of common stock issued to non-employee directors was 14,310 shares in 2015, 12,500 shares in 2014 and 11,656 shares in 2013. In 2015, the Compensation Committee granted restricted stock units (RSUs) and performance-based restricted stock units (PSUs) to select individuals in lieu of stock options. Each RSU represents the right to receive one share of common stock of the Corporation at a future date after the RSU has become earned and vested, subject to the terms and conditions of the RSU award agreement. The RSUs vest over a three-year period. The PSUs can be earned depending upon the achievement of a performance condition, a market condition and a time-vesting condition as follows: (1) achievement of a targeted basic earnings per share during the performance period of 2015 through 2017, (2) achievement of a three-year cumulative relative total shareholder return as ranked against other companies included in the Corporation’s peer group and (3) remaining continuously employed with the Corporation through December 31, 2017. Earlier vesting of the stock units is permitted under certain conditions, such as upon a change of control of the Corporation. A total of 90,836 RSUs and 26,263 unvested PSUs were granted during 2015. The weighted-average grant date fair value was $15.72 for the RSUs and $15.89 for the PSUs. The determination of the fair value of these awards takes into consideration the likelihood of achievement of the market condition. Compensation expense for PSUs is also based on the probability of achieving the targeted basic earnings per share and will be adjusted for subsequent changes in the estimated or actual outcome of the performance condition. In 2014 and 2013, the Compensation Committee granted non-qualified stock options. No stock options were granted during 2015. Options granted under the Incentive Plan have a ten-year life and vest over a three-year period. Options previously granted under earlier incentive plans have a ten-year life with one-third vesting at the date of grant, one-third vesting on the first anniversary date of the date of grant and one-third vesting on the second anniversary date of the date of grant. The exercise prices are equal to the closing prices of the Corporation’s common stock on the New York Stock Exchange on the dates of grant. The fair value of the options as of the dates of grant was calculated using the Black-Scholes option-pricing model based on the assumptions outlined below. Grant Date 2014 2013 Options granted 176,000 173,750 Exercise price $ 20.00 $ 17.16 Assumptions: Expected life in years 6 6 Risk-free interest rate 1.98% 1.26% Expected annual dividend yield 3.60% 4.20% Expected forfeiture rate 8.00% 5.00% Expected volatility 53.02% 52.68% Grant date fair value $ 7.40 $ 5.82 Resulting stock-based compensation expense $ 1,199 $ 961 A summary of stock options outstanding and exercisable and activity for the year ended December 31, 2015 is as follows: Shares Weighted Remaining Intrinsic Value Outstanding at January 1, 2015 1,202,169 $ 24.25 6.0 $ 778 Granted 0 N/A Exercised 0 N/A Forfeited (188,833 ) 25.43 Outstanding at December 31, 2015 1,013,336 $ 24.03 5.2 $ 0 Exercisable at December 31, 2015 867,586 $ 24.86 4.7 $ 0 Vested or expected to vest at December 31, 2015 1,013,336 $ 24.03 5.2 $ 0 Stock-based compensation expense, including expense for shares to be issued to non-employee directors, approximated $1,328, $1,102 and $1,196 for 2015, 2014 and 2013, respectively. The related income tax benefit recognized in the consolidated statements of operations was $465, $386 and $419 for the respective years. Unrecognized compensation expense equaled $1,701 at December 31, 2015 and is expected to be recognized over a weighted average period of 2 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	NOTE 11 – DERIVATIVE INSTRUMENTS: Certain operations of the Corporation are subject to risk from exchange rate fluctuations in connection with sales in foreign currencies. To minimize this risk, foreign currency sales contracts are entered into which are designated as cash flow or fair value hedges. As of December 31, 2015, approximately $11,566 of anticipated foreign-denominated sales has been hedged which are covered by fair value contracts settling at various dates through April 2017. The fair value of assets held as collateral for the fair value contracts as of December 31, 2015 approximated $800. Additionally, certain divisions of the Air and Liquid Processing segment are subject to risk from increases in the price of commodities (copper and aluminum) used in the production of inventory. To minimize this risk, futures contracts are entered into which are designated as cash flow hedges. At December 31, 2015, approximately 57% or $2,100 of anticipated copper purchases over the next nine months and 56% or $400 of anticipated aluminum purchases over the next six months are hedged. The Corporation previously entered into foreign currency purchase contracts to manage the volatility associated with euro-denominated progress payments to be made for certain machinery and equipment. As of December 31, 2010, all contracts had been settled and the underlying fixed assets were placed in service. No portion of the existing cash flow or fair value hedges is considered to be ineffective, including any ineffectiveness arising from the unlikelihood of an anticipated transaction to occur. Additionally, no amounts have been excluded from assessing the effectiveness of a hedge. At December 31, 2015, the Corporation has purchase commitments covering 49% or $2,799 of anticipated natural gas usage through 2017 for one of its subsidiaries. The commitments qualify as normal purchases and, accordingly, are not reflected on the consolidated balance sheet. Purchases of natural gas under previously existing commitments approximated $2,452, $2,190 and $2,694 for 2015, 2014 and 2013, respectively. The Corporation does not enter into derivative transactions for speculative purposes and, therefore, holds no derivative instruments for trading purposes. The following summarizes location and fair value of the foreign currency sales contracts recorded on the consolidated balance sheets as of December 31: Location 2015 2014 Cash flow hedge contracts Other current assets $ 10 $ 6 Fair value hedge contracts Other current assets 113 217 Other noncurrent assets 0 15 Other current liabilities 258 399 Other noncurrent liabilities 49 5 Fair value hedged item Accounts receivable 27 69 Other current assets 255 327 Other noncurrent assets 39 4 Other current liabilities 116 218 Other noncurrent liabilities 0 35 The change in the fair value of the cash flow contracts is recorded as a component of accumulated other comprehensive loss.

Deferred income tax assets and liabilities as of December 31, 2015 and 2014 are summarized below. Unremitted earnings of the Corporation’s non-U.S. subsidiaries and affiliates are deemed to be permanently reinvested and, accordingly, no deferred income tax liability has been recorded. It is not practical to estimate the income tax effect that might be incurred if cumulative prior year earnings not previously taxed in the United States were remitted to the United States. 2015 2014 Assets: Employment – related liabilities $ 9,644 $ 10,726 Pension liability – foreign 2,822 4,041 Pension liability – domestic 12,934 15,849 Liabilities related to discontinued operations 704 733 Capital loss carryforwards 223 253 Asbestos-related liability 16,356 18,252 Net operating loss – state 1,445 2,029 Inventory related 4,292 3,458 Impairment charge associated with investment in UES-MG 2,298 2,344 Other 3,311 3,546 Gross deferred income tax assets 54,029 61,231 Valuation allowance (2,481 ) (3,254 ) 51,548 57,977 Liabilities: Depreciation (29,223 ) (30,429 ) Mark-to-market adjustment – derivatives (40 ) (23 ) Other (1,716 ) (1,993 ) Gross deferred income tax liabilities (30,979 ) (32,445 ) Net deferred income tax assets $ 20,569 $ 25,532 The following summarizes changes in unrecognized tax benefits for the year ended December 31: 2015 2014 2013 Balance at the beginning of the year $ 52 $ 270 $ 442 Gross increases for tax positions taken in the current year 0 0 8 Gross increases for tax positions taken in prior years 283 2 12 Gross decreases in tax positions due to lapse in statute of limitations (20 ) (61 ) 0 Gross decreases for tax positions taken in prior years 0 (17 ) (192 ) Gross decreases for tax settlements with taxing authorities 0 (142 ) 0 Balance at the end of the year $ 315 $ 52 $ 270 If the unrecognized tax benefits were recognized, $65 would reduce the Corporation’s effective income tax rate. The amount of penalties and interest recognized in the consolidated balance sheets as of December 31, 2015 and 2014 and in the consolidated statements of operations for 2015, 2014 and 2013 is insignificant. Unrecognized tax benefits of $97 are to expire due to the lapse in the statute of limitations within the next 12 months. The Corporation is subject to taxation in the United States, various states and foreign jurisdictions, and remains subject to examination by tax authorities for tax years 2012-2015. The combined Indiana income tax returns for 2010-2013 are under examination by the Indiana Department of Revenue which started during the first quarter of 2015. The examination is still ongoing as of December 31, 2015.

Litigation

Text Block [Abstract]
Litigation	NOTE 17 – LITIGATION: The Corporation and its subsidiaries are involved in various claims and lawsuits incidental to their businesses and are also subject to asbestos litigation as described below. Asbestos Litigation Claims have been asserted alleging personal injury from exposure to asbestos-containing components historically used in some products of predecessors of Air & Liquid Systems Corporation (“Asbestos Liability”). Those subsidiaries, and in some cases the Corporation, are defendants (among a number of defendants, often in excess of 50) in cases filed in various state and federal courts. Asbestos Claims The following table reflects approximate information about the claims for Asbestos Liability against the subsidiaries and the Corporation for the two years ended December 31, 2015 and 2014: 2015 2014 Total claims pending at the beginning of the period 8,457 8,319 New claims served 1,424 1,466 Claims dismissed (3,339 ) (1,094 ) Claims settled (330 ) (234 ) Total claims pending at the end of the period (1) 6,212 8,457 Gross settlement and defense costs (in 000’s) $ 19,199 $ 20,801 Average gross settlement and defense costs per claim resolved (in 000’s) $ 5.23 $ 15.66 (1) Included as “open claims” are approximately 430 and 1,647 claims in 2015 and 2014, respectively, classified in various jurisdictions as “inactive” or transferred to a state or federal judicial panel on multi-district litigation, commonly referred to as the MDL. A substantial majority of the settlement and defense costs reflected in the above table was reported and paid by insurers. Because claims are often filed and can be settled or dismissed in large groups, the amount and timing of settlements, as well as the number of open claims, can fluctuate significantly from period to period. Asbestos Insurance The Corporation and its Air & Liquid Systems Corporation (“Air & Liquid”) subsidiary are parties to a series of settlement agreements (“Settlement Agreements”) with insurers that have coverage obligations for Asbestos Liability (the “Settling Insurers”). Under the Settlement Agreements, the Settling Insurers accept financial responsibility, subject to the terms and conditions of the respective agreements, including overall coverage limits, for pending and future claims for Asbestos Liability. The Settlement Agreements encompass the substantial majority of insurance policies that provide coverage for claims for Asbestos Liability. The Settlement Agreements include acknowledgements that Howden North America, Inc. (“Howden”) is entitled to coverage under policies covering Asbestos Liability for claims arising out of the historical products manufactured or distributed by Buffalo Forge, a former subsidiary of the Corporation (the “Products”). The Settlement Agreements do not provide for any prioritization on access to the applicable policies or any sublimits of liability as to Howden or the Corporation and Air & Liquid, and, accordingly, Howden may access the coverage afforded by the Settling Insurers for any covered claim arising out of a Product. In general, access by Howden to the coverage afforded by the Settling Insurers for the Products will erode coverage under the Settlement Agreements available to the Corporation and Air & Liquid for Asbestos Liability. On February 24, 2011, the Corporation and Air & Liquid filed a lawsuit in the United States District Court for the Western District of Pennsylvania against thirteen domestic insurance companies, certain underwriters at Lloyd’s, London and certain London market insurance companies, and Howden. The lawsuit seeks a declaratory judgment regarding the respective rights and obligations of the parties under excess insurance policies that were issued to the Corporation from 1981 through 1984 as respects claims against the Corporation and its subsidiary for Asbestos Liability and as respects asbestos bodily-injury claims against Howden arising from the Products. The Corporation and Air & Liquid have reached Settlement Agreements with all but two of the defendant insurers in the coverage action. Those Settlement Agreements specify the terms and conditions upon which the insurer parties are to contribute to defense and indemnity costs for claims for Asbestos Liability. One of the Settlement Agreements entered into by the Corporation and Air & Liquid also provided for the dismissal of claims, without prejudice, regarding two upper-level excess policies issued by one of the insurers. The Court has entered Orders dismissing all claims in the action filed against each other by the Corporation and Air & Liquid, on the one hand, and by the settling insurers, on the other. Howden also reached an agreement with eight domestic insurers addressing asbestos-related bodily injury claims arising from the Products, and claims as to those insurers and Howden have been dismissed. Various counterclaims, cross claims and third party claims have been filed in the litigation and remain pending although only two domestic insurers and Howden remain in the litigation as to the Corporation and Air & Liquid. On September 27, 2013, the Court issued a memorandum opinion and order granting in part and denying in part cross motions for summary judgment filed by the Corporation and Air & Liquid, Howden, and the insurer parties still in the litigation. On February 26, 2015, the Court issued final judgment. One insurer filed a notice of appeal from the judgment to the U.S. Court of Appeals to the Third Circuit; as a result, several other insurers, Howden, the Corporation, and Air & Liquid filed notices of case appeal. The appeals are presently pending, and the parties have been involved in a mediation through the Third Circuit’s mediator’s office. Asbestos Valuations In 2006, the Corporation retained Hamilton, Rabinovitz & Associates, Inc. (“HR&A”), a nationally recognized expert in the valuation of asbestos liabilities, to assist the Corporation in estimating the potential liability for pending and unasserted future claims for Asbestos Liability. HR&A was not requested to estimate asbestos claims against the inactive subsidiary in dissolution, which the Corporation believes are immaterial. Based on this analysis, the Corporation recorded a reserve for Asbestos Liability claims pending or projected to be asserted through 2013 as of December 31, 2006. HR&A’s analysis has been periodically updated since that time. Most recently, the HR&A analysis was updated in 2014, and additional reserves were established by the Corporation as of December 31, 2014 for Asbestos Liability claims pending or projected to be asserted through 2024. The methodology used by HR&A in its projection in 2014 of the operating subsidiaries’ liability for pending and unasserted potential future claims for Asbestos Liability, which is substantially the same as the methodology employed by HR&A in prior estimates, relied upon and included the following factors: • HR&A’s interpretation of a widely accepted forecast of the population likely to have been exposed to asbestos; • epidemiological studies estimating the number of people likely to develop asbestos-related diseases; • HR&A’s analysis of the number of people likely to file an asbestos-related injury claim against the subsidiaries and the Corporation based on such epidemiological data and relevant claims history from January 1, 2012 to December 8, 2014; • an analysis of pending cases, by type of injury claimed and jurisdiction where the claim is filed; • an analysis of claims resolution history from January 1, 2012 to December 8, 2014 to determine the average settlement value of claims, by type of injury claimed and jurisdiction of filing; and • an adjustment for inflation in the future average settlement value of claims, at an annual inflation rate based on the Congressional Budget Office’s ten year forecast of inflation. Using this information, HR&A estimated in 2014 the number of future claims for Asbestos Liability that would be filed through the year 2024, as well as the settlement or indemnity costs that would be incurred to resolve both pending and future unasserted claims through 2024. This methodology has been accepted by numerous courts. In conjunction with developing the aggregate liability estimate referenced above, the Corporation also developed an estimate of probable insurance recoveries for its Asbestos Liabilities. In developing the estimate, the Corporation considered HR&A’s projection for settlement or indemnity costs for Asbestos Liability and management’s projection of associated defense costs (based on the current defense to indemnity cost ratio), as well as a number of additional factors. These additional factors included the Settlement Agreements then in effect, policy exclusions, policy limits, policy provisions regarding coverage for defense costs, attachment points, prior impairment of policies and gaps in the coverage, policy exhaustions, insolvencies among certain of the insurance carriers, and the nature of the underlying claims for Asbestos Liability asserted against the subsidiaries and the Corporation as reflected in the Corporation’s asbestos claims database, as well as estimated erosion of insurance limits on account of claims against Howden arising out of the Products. In addition to consulting with the Corporation’s outside legal counsel on these insurance matters, the Corporation consulted with a nationally-recognized insurance consulting firm it retained to assist the Corporation with certain policy allocation matters that also are among the several factors considered by the Corporation when analyzing potential recoveries from relevant historical insurance for Asbestos Liabilities. Based upon all of the factors considered by the Corporation, and taking into account the Corporation’s analysis of publicly available information regarding the credit-worthiness of various insurers, the Corporation estimated the probable insurance recoveries for Asbestos Liability and defense costs through 2024. Although the Corporation believes that the assumptions employed in the insurance valuation were reasonable and previously consulted with its outside legal counsel and insurance consultant regarding those assumptions, there are other assumptions that could have been employed that would have resulted in materially lower insurance recovery projections. Based on the analyses described above, the Corporation’s reserve at December 31, 2014 for the total costs, including defense costs, for Asbestos Liability claims pending or projected to be asserted through 2024 was $189,048 of which approximately 64% was attributable to settlement costs for unasserted claims projected to be filed through 2024 and future defense costs. The reserve at December 31, 2015 was $169,849. While it is reasonably possible that the Corporation will incur additional charges for Asbestos Liability and defense costs in excess of the amounts currently reserved, the Corporation believes that there is too much uncertainty to provide for reasonable estimation of the number of future claims, the nature of such claims and the cost to resolve them beyond 2024. Accordingly, no reserve has been recorded for any costs that may be incurred after 2024. The Corporation’s receivable at December 31, 2014 for insurance recoveries attributable to the claims for which the Corporation’s Asbestos Liability reserve has been established, including the portion of incurred defense costs covered by the Settlement Agreements in effect through December 31, 2014, and the probable payments and reimbursements relating to the estimated indemnity and defense costs for pending and unasserted future Asbestos Liability claims, was $140,651 ($125,423 at December 31, 2015). The following table summarizes activity relating to insurance recoveries for each of the years ended December 31, 2015 and 2014. 2015 2014 Insurance receivable – asbestos, beginning of the year $ 140,651 $ 110,741 Settlement and defense costs paid by insurance carriers (15,228 ) (17,159 ) Changes in estimated coverage 0 47,069 Insurance receivable – asbestos, end of the year $ 125,423 $ 140,651 The insurance receivable recorded by the Corporation does not assume any recovery from insolvent carriers and a substantial majority of the insurance recoveries deemed probable was from insurance companies rated A – (excellent) or better by A.M. Best Corporation. There can be no assurance, however, that there will not be further insolvencies among the relevant insurance carriers, or that the assumed percentage recoveries for certain carriers will prove correct. The difference between insurance recoveries and projected costs is not due to exhaustion of all insurance coverage for Asbestos Liability. The Corporation and the subsidiaries have substantial additional insurance coverage which the Corporation expects to be available for Asbestos Liability claims and defense costs that the subsidiaries and it may incur after 2024. However, this insurance coverage also can be expected to have gaps creating significant shortfalls of insurance recoveries as against claims expense, which could be material in future years. The amounts recorded by the Corporation for Asbestos Liabilities and insurance receivables rely on assumptions that are based on currently known facts and strategy. The Corporation’s actual expenses or insurance recoveries could be significantly higher or lower than those recorded if assumptions used in the Corporation’s or HR&A’s calculations vary significantly from actual results. Key variables in these assumptions are identified above and include the number and type of new claims to be filed each year, the average cost of disposing of each such new claim, average annual defense costs, compliance by relevant parties with the terms of the Settlement Agreements, the resolution of remaining coverage issues with insurance carriers, and the solvency risk with respect to the relevant insurance carriers. Other factors that may affect the Corporation’s Asbestos Liability and ability to recover under its insurance policies include uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, reforms that may be made by state and federal courts, and the passage of state or federal tort reform legislation. The Corporation intends to evaluate its estimated Asbestos Liability and related insurance receivables as well as the underlying assumptions on a regular basis to determine whether any adjustments to the estimates are required. Due to the uncertainties surrounding asbestos litigation and insurance, these regular reviews may result in the Corporation incurring future charges; however, the Corporation is currently unable to estimate such future charges. Adjustments, if any, to the Corporation’s estimate of its recorded Asbestos Liability and/or insurance receivables could be material to operating results for the periods in which the adjustments to the liability or receivable are recorded, and to the Corporation’s liquidity and consolidated financial position.

Summary of Significant Accoun34

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Consolidation	Consolidation All subsidiaries are wholly owned and are included in the consolidated financial statements of the Corporation. Intercompany accounts and transactions are eliminated. Investments in joint ventures where the Corporation owns 20% to 50% of the voting stock and has the ability to exercise significant influence over the operating and financial policies of the joint venture are accounted for using the equity method of accounting. Investments in joint ventures whereby the Corporation does not have the ability to exercise significant influence over the operating and financial policies of the joint venture are accounted for using the cost method of accounting. Investments in joint ventures are reviewed for impairment whenever events or circumstances indicate the carrying amount of the investment may not be recoverable. If the estimated fair value of the investment is less than the carrying amount and such decline is determined to be “other than temporary,” then the investment may not be fully recoverable potentially resulting in a write-down of the investment value.
Cash and Cash Equivalents	Cash and Cash Equivalents Securities with purchased original maturities of three months or less are considered to be cash equivalents. The Corporation maintains cash and cash equivalents at various financial institutions which may exceed federally insured amounts.
Inventories	Inventories Inventories are valued at the lower of cost or market. Cost includes the cost of raw materials, direct labor and overhead for those items manufactured but not yet sold or for which title has not yet transferred. Fixed production overhead is allocated to inventories based on normal capacity of the production facilities. In periods of abnormally high production, the amount of fixed overhead allocated to each unit of production is decreased so that inventories are not measured above cost. The amount of fixed overhead allocated to inventories is not increased as a consequence of abnormally low production or idle plant. Costs for abnormal amounts of spoilage, handling costs and freight costs are charged to expense when incurred. Cost of domestic raw materials, work-in-process and finished goods inventories is primarily determined by the last-in, first-out (LIFO) method. Cost of domestic supplies and foreign inventories is determined primarily by the first-in, first-out (FIFO) method.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost with depreciation computed using the straight-line method over the following estimated useful lives: land improvements – 15 to 20 years, buildings – 25 to 50 years and machinery and equipment – 3 to 25 years. Expenditures that extend economic useful lives are capitalized. Routine maintenance is charged to expense. Gains or losses are recognized on retirements or disposals. Property, plant and equipment are reviewed for impairment whenever events or circumstances indicate the carrying amount of the asset may not be recoverable. If the undiscounted cash flows generated from the use and eventual disposition of the assets are less than their carrying value, then the asset value may not be fully recoverable potentially resulting in a write-down of the asset value. Estimates of future cash flows are based on expected market conditions over the remaining useful life of the primary asset(s). Proceeds from government grants are recorded as a reduction in the purchase price of the underlying assets and amortized against depreciation over the lives of the related assets.
Product Warranty	Product Warranty Provisions for product warranties are recognized at the time the underlying sale is recorded. The provision is based on historical experience as a percentage of sales adjusted for potential claims when a liability is probable and for known claims.
Employee Benefit Plans	Employee Benefit Plans Funded Status If the fair value of the plan assets exceeds the projected benefit obligation, the over-funded projected benefit obligation is recognized as an asset (prepaid pensions) on the consolidated balance sheet. Conversely, if the projected benefit obligation exceeds the fair value of the plan assets, the under-funded projected benefit obligation is recognized as a liability (employee benefit obligations) on the consolidated balance sheet. Gains and losses arising from the difference between actuarial assumptions and actual experience and unamortized prior service costs are recorded as a separate component of accumulated other comprehensive loss and presented net of income tax. Net Periodic Pension and Other Postretirement Costs Net periodic pension and other postretirement costs includes service cost, interest cost, expected rate of return on the market-related value of plan assets, amortization of prior service costs and recognized actuarial gains or losses. When actuarial gains or losses exceed 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are amortized to net periodic pension and other postretirement costs over the average remaining service period of employees expected to receive benefits under the plan. When the actuarial gains or losses are less than 10% of the greater of the projected benefit obligation or the market-related value of plan assets, they are included in net periodic pension and other postretirement costs indirectly as a result of lower/higher interest costs arising from a decrease/increase in the projected benefit obligation. The market-related value of plan assets is determined using a five-year moving average which recognizes 20% of unrealized gains and losses each year.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Other comprehensive income (loss) includes changes in assets and liabilities from non-owner sources including foreign currency translation adjustments, unamortized prior service costs and unrecognized actuarial gains and losses associated with employee benefit plans, unrealized holding gains and losses on securities designated as available for sale and changes in the fair value of derivatives designated and effective as cash flow hedges. Certain components of other comprehensive income (loss) are presented net of income tax. Foreign currency translation adjustments exclude the effect of income tax since earnings of non-U.S. subsidiaries are deemed to be reinvested for an indefinite period of time. Reclassification adjustments are amounts which are realized during the year and, accordingly, are deducted from other comprehensive income (loss) in the period in which they are included in net income (loss) or when a transaction no longer qualifies as a cash flow hedge. Foreign currency translation adjustments are included in net income (loss) upon sale or upon complete or substantially complete liquidation of an investment in a foreign entity. With respect to employee benefit plans, unamortized prior service costs are included in net income (loss) either immediately upon curtailment of the employee benefit plan or over the average remaining service period of employees expected to receive benefits and unrecognized actuarial gains and losses are included in net income (loss) indirectly as a result of lower/higher interest costs arising from a decrease/increase in the projected benefit obligation. Unrealized holding gains and losses on securities are included in net income (loss) when the underlying security is sold. Changes in the fair value of derivatives are included in net income (loss) when the projected sale occurs or, if a foreign currency purchase contract, over the estimated useful life of the underlying asset.
Revenue Recognition	Revenue Recognition Revenue from sales is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Persuasive evidence of an arrangement identifies the final understanding between the parties as to the specific nature and terms of the agreed-upon transaction that creates enforceable obligations. It can be in the form of an executed purchase order from the customer, sales agreement issued by the Corporation or a similar arrangement deemed to be normal and customary business practice for that particular customer or class of customer (collectively, a sales agreement). Delivery and performance is considered to have occurred when the customer has taken title and assumed the risks and rewards of ownership of the product. Typically this occurs when the product is shipped to the customer (i.e., FOB shipping point), delivered to the customer (i.e., FOB destination), or, for foreign sales, in accordance with trading guidelines known as Incoterms. Incoterms are standard trade definitions used in international contracts and are developed, maintained and promoted by the ICC Commission on Commercial Law and Practice. The sales price required to be paid by the customer is fixed or determinable from the sales agreement. It is not subject to refund or adjustment except for a variable-index surcharge provision which increases or decreases, as applicable, the selling price of a rolling mill roll for corresponding changes in the published index cost of certain raw materials. The variable-index surcharge is recognized as revenue when the corresponding revenue for the inventory is recognized. Likelihood of collectability is assessed prior to acceptance of an order. There are no customer-acceptance provisions other than customer inspection and testing prior to shipment. Post-shipment obligations are insignificant. Amounts billed to the customer for shipping and handling are recorded within net sales and the related costs are recorded within costs of products sold (excluding depreciation). Amounts billed for taxes assessed by various government authorities (e.g. sales tax, value-added tax, etc.) are excluded from the determination of net income and instead are recorded as a liability until remitted to the government authority.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of the Corporation’s foreign operations are translated at year-end exchange rates and the statements of operations are translated at the average exchange rates for the year. Gains or losses resulting from translating foreign currency financial statements are accumulated as a separate component of accumulated other comprehensive loss until the entity is sold or substantially liquidated.
Derivative Instruments	Derivative Instruments Derivative instruments which include forward exchange (for foreign currency sales and purchases) and futures contracts are recorded on the consolidated balance sheet as either an asset or a liability measured at their fair value. The accounting for changes in the fair value of a derivative depends on the use of the derivative. To the extent that a derivative is designated and effective as a cash flow hedge of an exposure to future changes in value, the change in the fair value of the derivative is deferred in accumulated other comprehensive loss. Any portion considered to be ineffective, including that arising from the unlikelihood of an anticipated transaction to occur, is reported as a component of earnings (other income/expense) immediately. Upon occurrence of the anticipated sale, the foreign currency sales contract designated and effective as a cash flow hedge is de-designated as a fair value hedge and the change in fair value previously deferred in accumulated other comprehensive loss is reclassified to earnings (net sales) with subsequent changes in fair value recorded as a component of earnings (other income/expense). Upon occurrence of the anticipated purchase, the foreign currency purchase contract is settled and the change in fair value deferred in accumulated other comprehensive loss is reclassified to earnings (depreciation expense) over the life of the underlying assets. Upon settlement of a futures contract, the change in fair value deferred in accumulated other comprehensive loss is reclassified to earnings (costs of products sold, excluding depreciation) when the corresponding inventory is sold and revenue is recognized. To the extent that a derivative is designated and effective as a hedge of an exposure to changes in fair value, the change in the derivative’s fair value will be offset in the statement of operations by the change in the fair value of the item being hedged and is recorded as a component of earnings (other income/expense). Cash flows associated with the derivative instruments are recorded as a component of operating activities on the consolidated statement of cash flows. The Corporation does not enter into derivative transactions for speculative purposes and, therefore, holds no derivative instruments for trading purposes.
Fair Value	Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. A hierarchy of inputs is used to determine fair value measurements with three levels. Level 1 inputs are quoted prices in active markets for identical assets or liabilities and are considered the most reliable evidence of fair value. Level 2 inputs are observable prices that are not quoted on active exchanges. Level 3 inputs are unobservable inputs used for measuring the fair value of assets or liabilities.
Legal Costs	Legal Costs Legal costs expected to be incurred in connection with loss contingencies are accrued when such costs are probable and estimable.
Income Taxes	Income Taxes Income taxes are recognized during the year in which transactions enter into the determination of financial statement income. Deferred income tax assets and liabilities are recognized for the future tax consequences of temporary differences between the book carrying amount and the tax basis of assets and liabilities including net operating loss carryforwards. Unremitted earnings of the Corporation’s non-U.S. subsidiaries and affiliates are deemed to be permanently reinvested and, accordingly, no deferred income tax liability is recorded. A valuation allowance is provided against a deferred income tax asset when it is “more likely than not” the asset will not be realized. Similarly, if a determination is made that it is “more likely than not” the deferred income tax asset will be realized, the related valuation allowance would be reduced and a benefit to earnings would be recorded. Penalties and interest are recognized as a component of the income tax provision. Tax benefits are recognized in the financial statements for tax positions taken or expected to be taken in a tax return when it is “more likely than not” that the tax authorities will sustain the tax position solely on the basis of the position’s technical merits. Consideration is given primarily to legislation and statutes, legislative intent, regulations, rulings and case law as well as their applicability to the facts and circumstances of the tax position when assessing the sustainability of the tax position. In the event a tax position no longer meets the “more likely than not” criteria, the tax benefit is reversed by recognizing a liability and recording a charge to earnings. Conversely, if a tax position subsequently meets the “more likely than not” criteria, a tax benefit would be recognized by reducing the liability and recording a credit to earnings.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. The computation of diluted earnings per common share is similar to basic earnings per common share except that the denominator is increased to include the dilutive effect of the net additional common shares that would have been outstanding assuming exercise of outstanding stock awards, calculated using the treasury stock method. The computation of diluted earnings per share would not assume the exercise of an outstanding stock award if the effect on earnings per common share would be antidilutive. Similarly, the computation of diluted earnings per share would not assume the exercise of outstanding stock awards if the Corporation incurred a net loss since the effect on earnings per common share would be antidilutive. The weighted average number of common shares outstanding assuming exercise of dilutive stock awards was 10,447,066 for 2015, 10,404,744 for 2014 and 10,406,478 for 2013. Weighted-average outstanding stock awards excluded from the diluted earnings per common share calculation, since the effect would have been antidilutive, were 1,138,287 for 2015, 1,242,545 for 2014 and 781,325 for 2013.
