Accounting Policies [Abstract]
Accounting Principals and Practices	Accounting Principles and Practices Advertising Costs associated with advertising are expensed as incurred and are included in Selling expense in the Consolidated Statements of Operations. Advertising expenses were $2,452,000 , $2,683,000 , and $1,748,000 in fiscal 2019 , 2018 , and 2017 , respectively. Cash and Cash Equivalents The Company considers as cash equivalents all highly liquid investments with an original maturity of three months or less. Concentrations of Labor Approximately 10% of the Company’s employees are represented by three separate U.S. collective bargaining agreements which expire May 2020 , April 2021, and September 2021 . Consolidation These consolidated financial statements include the accounts of the Company and its global subsidiaries; all significant intercompany accounts and transactions have been eliminated. Equity Method Investment The Company has an investment in Eastern Morris Cranes Company Limited ("EMC") whose principal activity is to manufacture various electrical overhead traveling cranes. This investment represents a minority ownership interest that is accounted for under the equity method of accounting since the Company has significant influence over the investee. As a result, the Company records its portion of the gains and losses incurred by this entity in Investment (income) loss in the Consolidated Statements of Operations. Foreign Currency Translations The Company translates foreign currency financial statements as described in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 830, “Foreign Currency Matters.” Under this method, all items of income and expense are translated to U.S. dollars at average exchange rates during the year. All assets and liabilities are translated to U.S. dollars at the year-end exchange rate. Gains or losses on translations are recorded in accumulated other comprehensive loss in the shareholders’ equity section of the balance sheet. The functional currency is the foreign currency in which the foreign subsidiaries conduct their business. Gains and losses from foreign currency transactions are reported in foreign currency exchange loss (gain). Goodwill Goodwill is not amortized but is tested for impairment at least annually, or more frequently if indicators of impairment exist, in accordance with the provisions of ASC Topic 350-20-35-1. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. The fair value of a reporting unit is determined using a discounted cash flow methodology. The Company’s reporting units are determined based upon whether discrete financial information is available and reviewed regularly, whether those units constitute a business, and the extent of economic similarities and interdependencies between those reporting units for purposes of aggregation. The Company’s reporting units identified under ASC Topic 350-20-35-33 are at the component level, or one level below the reporting segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting – Disclosure.” As of March 31, 2019, the Company’s one segment is subdivided into two reporting units. Further, the Company adopted ASU No. 2017-04, "Simplifying the Test for Goodwill Impairment (Topic 350)," in fiscal 2018, therefore, is no longer required to compare the implied fair value of goodwill with its carrying value amount as part of step two of the goodwill test. An impairment charge is the amount by which the carrying value is greater than the reporting unit's fair value (step one). When the Company evaluates the potential for goodwill impairment, it assesses a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for its products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value or if economic or other business factors indicate that the fair value of our reporting units may have declined since our last quantitative test, the Company performs a quantitative test. To perform the quantitative impairment test, the Company uses the discounted cash flow method to estimate the fair value of the reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating profit margins and cash flows, the terminal growth rate, and the discount rate. The Company projects revenue growth rates, operating margins and cash flows based on each reporting unit’s current business, expected developments and operational strategies over a five-year period. In estimating the terminal growth rate, the Company considers its historical and projected results, as well as the economic environment in which its reporting units operate. The discount rates utilized for each reporting unit reflect the Company’s assumptions of marketplace participants’ cost of capital and risk assumptions, both specific to the reporting unit and overall in the economy. The Company performed its qualitative assessment as of February 28, 2019 and determined that the quantitative goodwill impairment test was not required for the Rest of Products reporting unit. Based on various conditions in the current fiscal year, such as financial performance, macroeconomic conditions, and other company specific events, the Rest of Products reporting unit's fair value was likely not less than its applicable carrying value. The qualitative assessment for the Duff-Norton reporting unit indicated that a quantitative test should be performed. Based on results of the quantitative impairment test for the Duff-Norton reporting unit, the Company determined the fair value was not less than its carrying value. See Note 9 for further discussion of goodwill and intangible assets. Impairment of Long-Lived Assets The Company assesses impairment of its long-lived assets in accordance with the provisions of ASC Topic 360 “Property, Plant, and Equipment.” This statement requires long-lived assets, such as property and equipment and purchased intangibles subject to amortization, to be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to estimated undiscounted future cash flows expected to be generated by the asset group over its remaining useful life. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized equal to the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. The fair values are determined in accordance with ASC 820. In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Asset grouping requires a significant amount of judgment. Accordingly, facts and circumstances will influence how asset groups are determined for impairment testing. In assessing long-lived assets for impairment, management considered the Company’s product line portfolio, customers and related commercial agreements, labor agreements and other factors in grouping assets and liabilities at the lowest level for which identifiable cash flows are independent. The Company considers projected future undiscounted cash flows, trends and other factors in its assessment of whether impairment conditions exist. While the Company believes that its estimates of future cash flows are reasonable, different assumptions regarding such factors as future production volumes, customer pricing, economics, and productivity and cost initiatives, could significantly affect its estimates. In determining fair value of long-lived assets, management uses management estimates, discounted cash flow calculations, and appraisals where necessary. Other than the impairment on Held for Sale Businesses, discussed in Note 3, no impairment was recorded related to long-lived assets in the current year. Intangible Assets At acquisition, the Company estimates and records the fair value of purchased intangible assets which primarily consist of trade names, customer relationships, and technology. The fair values are estimated based on management’s assessment as well as independent third party appraisals. Such valuations may include a discounted cash flow of anticipated revenues resulting from the acquired intangible asset. Amortization of intangible assets with finite lives is recognized over their estimated useful lives using an amortization method that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise realized. The straight line method is used for customer relationships. As a result of the negligible attrition rate in our customer base, the difference between the straight line method and attrition method is not considered significant. The estimated useful lives for our intangible assets range from 1 to 25 years. Similar to goodwill, indefinite-lived intangible assets (including trademarks on our acquisitions) are tested for impairment on an annual basis. When the Company evaluates the potential for impairment of intangible assets, it assesses a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for its products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value or if economic or other business factors indicate that the fair value of our indefinite-lived intangible assets may have declined since our last quantitative test, the Company performs a new quantitative test. The methodology used to value trademarks is the relief from royalty method. The recorded book value of these trademarks in excess of the calculated fair value triggers an impairment. The key estimate used in this calculation consists of an overall royalty rate applied to the sales covered by the trademark. After performing a qualitative assessment as of February 28, 2019 , it was determined that the trademarks were not impaired. Inventories Inventories are valued at the lower of cost and net realizable value. Cost of approximately 36% and 30% of inventories at March 31, 2019 and March 31, 2018 , respectively, have been determined using the LIFO (last-in, first-out) method. Costs of other inventories have been determined using the FIFO (first-in, first-out) or average cost method. FIFO cost approximates replacement cost. Costs in inventory include components for direct labor and overhead costs. Marketable Securities The Company’s marketable securities, which consist of equity and fixed income securities, are recorded at fair value. As described in Note 7, in the first quarter of fiscal 2019 the Company adopted ASU 2016-01 whereas all equity investments (including certain fixed income securities) in unconsolidated entities are measured at fair value through earnings. Therefore, gains and losses on marketable securities are no longer recorded in Shareholders' equity on the Consolidated Balance Sheets, rather, are realized within Investment (income) loss on the Consolidated Statements of Operations. Estimated fair value is based on published trading values at the balance sheet dates. The cost of securities sold is based on the specific identification method. Interest and dividend income are also included in Investment (income) loss on the Consolidated Statements of Operations. The marketable securities are carried as long-term assets since they are held for the settlement of the Company’s general and products liability insurance claims filed through CM Insurance Company, Inc., a wholly owned captive insurance subsidiary. The marketable securities are not available for general working capital purposes. Property, Plant, and Equipment Property, plant, and equipment are stated at cost and depreciated principally using the straight-line method over their respective estimated useful lives (buildings and building equipment— 15 to 40 years; machinery and equipment— 3 to 18 years). When depreciable assets are retired, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operating results. Research and Development With the acquisitions of Magnetek in September 2015 and STAHL CraneSystems (“STAHL”) in January 2017, the Company expects research and development ("R&D") costs to factor more prominently into its cost structure. Therefore, R&D costs are presented on the Consolidated Statement of Operations in order to provide transparency into these costs. Consistent with prior periods, the Company continues to account for R&D expenses in accordance with the provisions of ASC 730 and are expensed as incurred. Revenue Recognition, Accounts Receivable, and Concentration of Credit Risk As described in Note 4, the Company adopted ASC 606, "Revenue from Contracts with Customers," in fiscal 2019. Revenue from contracts with customers for standard products is recognized when legal title and significant risk and rewards has transferred to the customer, which is generally at the time of shipment. This is the point in time when control is deemed to transfer to the customer. The Company also sells custom engineered products and services which are contracts that are typically completed within one quarter but can extend beyond one year in duration. The Company generally recognizes revenue for customer engineered products upon satisfaction of its performance obligation under the contract which typically coincides with project completion which is when the products and services are controlled by the customer. Control is typically achieved at the later of when legal title and significant risk and rewards have transferred to the customer or the customer has accepted the asset. For both standard products and custom engineered products, the transaction price is based upon the price stated in either the purchase order or contract. Refer to Note 4 for further details. Additionally, the Company performs ongoing credit evaluations of its customers’ financial condition, but generally does not require collateral to support customer receivables. The credit risk is controlled through credit approvals, limits, and monitoring procedures. Accounts receivable are reported at net realizable value and do not accrue interest. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends, and other factors. Accounts receivable are charged against the allowance for doubtful accounts once all collection efforts have been exhausted. The Company does not routinely permit customers to return product. However, sales returns are permitted in specific situations and typically include a restocking charge or the purchase of additional product. Shipping and Handling Costs Shipping and handling costs are a component of cost of products sold. Stock-Based Compensation The Company records stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation.” This standard requires all equity-based payments to employees, including grants of employee stock options, to be recognized in the Consolidated Statements of Operations based on the grant date fair value of the award. Stock compensation expense is included in Cost of products sold, Selling, and General and administrative expense depending on the nature of the service of the employee receiving the award. The Company uses a straight-line method of attributing the value of stock compensation expense, subject to minimum levels of expense, based on vesting. See Note 15 for further discussion of stock-based compensation. Leases All leases are reviewed for capital or operating classification at their inception. Rent expense for leases that contain scheduled rent increases is recognized on a straight-line basis over the lease term. As a result of ASC 842, "Leases," which is discussed in Note 22 and effective in fiscal 2020, the Company is currently updating existing lease policies to comply with the new standard. In the current year, the Company implemented a policy requiring leases to be centralized and tracked in the Company's leasing software. The existing policy requiring a classification test prior to commencement in order to determine if the lease is operating or capital is not significantly impacted by the adoption of ASC 842, however, capital leases will be known as finance leases. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Warranties The Company offers warranties for certain products it sells. The specific terms and conditions of those warranties vary depending upon the product sold and the country in which the Company sold the product. As noted in the Revenue Recognition note (Note 4), the Company offers standard warranties which are typically 12 months in duration for standard products and 24 to 36 months for custom engineered products. These are assurance-type warranties that do not qualify as separate performance obligations under ASC 606. The Company estimates the costs that may be incurred under its standard warranties, based largely upon actual warranty repair costs history, and records a liability in the amount of such costs in the month that revenue is recognized. The resulting accrual balance is reviewed during the year. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rate of warranty claims, and cost per claim. Changes in the Company’s product warranty accrual are as follows: March 31, 2019 2018 Balance at beginning of year $ 3,791 $ 4,081 Accrual for warranties issued 3,405 2,716 Warranties settled (3,625 ) (3,006 ) Warranties on Sold Businesses (Note 3) (66 ) — Foreign currency translation 129 — Balance at end of year $ 3,634 $ 3,791

Business Combination, Step Acquisition [Abstract]
Acquisitions	Acquisitions and Disposals As part of our business strategy, Blueprint for Growth, in the first quarter of fiscal 2019 the Company started the process to sell its Tire Shredder business, its crane builder business, Crane Equipment and Service Inc., and Stahlhammer Bommern GmbH, its European forging business acquired in 2014 (the "Sold Businesses") as they were no longer considered part of the core business or a strategic fit with the Company's long-term growth and operational objectives. On December 28, 2018, the Company sold its Tire Shredder business and recognized a gain. On February 28, 2019 , the Company sold the remaining two businesses, Crane Equipment and Service Inc. and Stahlhammer Bommern GmbH, and recognized a loss. As such, there are no remaining businesses which meet the criteria as being held for sale as of March 31, 2019 in accordance with ASC 360-10-45-9, "Property, Plant, and Equipment." The businesses were not deemed a strategic shift or significant to be considered discontinued operations. When businesses or asset groups meet the criteria as held for sale, they are recorded at the lesser of their carrying value or fair value less cost to sell. The Company recognized a gain on the sale of its Tire Shredder business in the amount of $1,059,000 during the twelve months ending March 31, 2019 , a $44,000 decrease from the third quarter as a result of a final working capital adjustment. The Company recognized a loss on Crane Equipment and Service Inc., and Stahlhammer Bommern GmbH in the amount of $26,731,000 during the twelve months ended March 31, 2019 , which is $1,022,000 less than the third quarter estimate primarily as a result of an increase in the previously estimated selling price for one of the businesses. The recognized loss of $26,731,000 recognized during fiscal 2019 includes an impairment loss on the Sold Businesses in the amount of $27,753,000 which was recorded through December 31, 2018. The impairment loss included a $6,174,000 reduction to goodwill, a $1,872,000 reduction to other intangible assets, a $12,830,000 reduction to property, plant, and equipment, and a $6,877,000 reduction to inventory. Both the gain and loss on sale of business were recorded in Net loss on sales of businesses on the Consolidated Statements of Operations and was determined based on the selling price less carrying value, described further in Note 5. Additionally, net sales and pre-tax income (loss) before recognized gain or loss on sales for the three Sold Businesses was $34,195,000 and $3,623,000 for the twelve months ended March 31, 2019 , $38,299,000 and $1,373,000 for the twelve months ended March 31, 2018, and $36,055,000 and $(1,212,000) for the twelve months ended March 31, 2017, respectively. Additionally as part of the business strategy, the Company announced on October 26, 2018 that it plans to consolidate its hoist manufacturing facility in Salem, Ohio into the Lisbon, Ohio and Wadesboro, NC facilities early in fiscal 2020. Consolidation costs of $1,473,000 are included in Cost of Products sold on the Consolidated Statements of Operations during the twelve months ended March 31, 2019 , of which $1,007,000 is accrued as of March 31, 2019 . Costs incurred include accelerated depreciation, accelerated lease costs, severance and other payroll related costs, and a potential refund of a previously recorded tax credit which may need to be refunded to the state. See Note 5 for further details. On July 15, 2016, the Company purchased 100% of the assets of Ergomatic Products LLC ("Ergomatic"), a designer and manufacturer of ergonomic lift assists, articulating arms, torque tubes, and pneumatic control systems for material handling and tool suspension applications. In connection with the acquisition of Ergomatic, the Company withheld $588,000 to be paid to the seller upon satisfaction of certain conditions. The amounts withheld were classified as restricted cash at that time. Of this amount, $294,000 was paid to the seller in July 2017 and the remaining $294,000 was paid in July 2018.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC Topic 820 “Fair Value Measurements and Disclosures” establishes the standards for reporting financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value on a recurring basis (at least annually). Under these standards, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants at the measurement date. ASC Topic 820-10-35-37 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the valuation techniques that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is separated into three levels based on the reliability of inputs as follows: Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2 - Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly, involving some degree of judgment. Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The availability of observable inputs can vary and is affected by a wide variety of factors, including the type of asset/liability, whether the asset/liability is established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, assumptions are required to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Company primarily uses readily observable market data in conjunction with internally developed discounted cash flow valuation models when valuing its derivative portfolio and, consequently, the fair value of the Company’s derivatives is based on Level 2 inputs. The carrying amount of the Company's annuity contract is recorded at net asset value of the contract and, consequently, its fair value is based on Level 2 inputs and is included in other assets on the Company's Consolidated Balance Sheet. The Company uses quoted prices in an inactive market when valuing its term loan and, consequently, the fair value is based on Level 2 inputs. The carrying value of the Company’s senior debt approximates fair value based on current market interest rates for debt instruments of similar credit standing and, consequently, its fair value is based on Level 2 inputs. The following table provides information regarding financial assets and liabilities measured or disclosed at fair value on a recurring basis: Fair value measurements at reporting date using Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description At March 31, 2019 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) Measured at fair value: Marketable securities $ 7,028 $ 7,028 $ — $ — Annuity contract 2,285 — 2,285 — Derivative assets (liabilities): Foreign exchange contracts (70 ) — (70 ) — Interest rate swap asset 1,213 — 1,213 — Cross currency swap liability (16,184 ) — (16,184 ) — Cross currency swap asset 2,476 — 2,476 — Disclosed at fair value: Term loan $ (310,463 ) $ — $ (310,463 ) $ — Fair value measurements at reporting date using Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description At March 31, 2018 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) Measured at fair value: Marketable securities $ 7,673 $ 7,673 $ — $ — Annuity contract 2,575 — 2,575 — Derivative assets (liabilities): Foreign exchange contracts 107 — 107 — Interest rate swap asset 3,961 — 3,961 — Cross currency swap liability (40,237 ) — (40,237 ) — Cross currency swap asset 2,204 — 2,204 — Disclosed at fair value: Term loan $ (378,504 ) $ — $ (378,504 ) $ — Senior debt (98 ) — (98 ) — The Company did not have any non-financial assets and liabilities that are recognized at fair value on a recurring basis. At March 31, 2019 , the term loan and revolving credit facility have been recorded at carrying value which approximates fair value. Market gains, interest, and dividend income on marketable securities are recorded in investment (income) loss. Changes in the fair value of derivatives are recorded in foreign currency exchange (gain) loss or other comprehensive income (loss), to the extent that the derivative qualifies as a hedge under the provisions of ASC Topic 815. Interest and dividend income on marketable securities are measured based upon amounts earned on their respective declaration dates. Fiscal 2019 Non-Recurring Measurements Interim goodwill impairment test: As described in Note 9, the Company classified the assets and liabilities of certain businesses as held for sale during fiscal 2019. These businesses were sold prior to the end of fiscal 2019. As a result of this interim classification, the Company determined an indicator of impairment existed and was required to perform an interim goodwill impairment test on the Rest of Products goodwill reporting unit (representing the hoist, chain, forgings, digital power, motion control, manufacturing, and distribution businesses). The net assets of the Rest of Products reporting unit were measured on a non-recurring basis as of May 31, 2018 in order to perform the interim quantitative goodwill impairment test. The interim quantitative goodwill impairment test consisted of determining the fair value of the Rest of Products reporting units on a quantitative basis. The fair value for the Company’s Rest of Products reporting unit cannot be determined using readily available quoted Level 1 inputs or Level 2 inputs that are observable in active markets. Therefore, the Company used a blended discounted cash flow and market-based valuation model to estimate the fair value using Level 3 inputs. To estimate the fair value of the Rest of Products reporting unit, the Company used significant estimates and judgmental factors. The key estimates and factors used in the discounted cash flow valuation include revenue growth rates and profit margins based on internal forecasts, terminal value, and the weighted-average cost of capital used to discount future cash flows. The compound annual growth rate for revenue during the first five years of the projections was approximately 3.75% . The terminal value was calculated assuming a projected growth rate of 3.0% after five years. The estimated weighted-average cost of capital for the Rest of Products reporting unit was determined to be 11.1% based upon an analysis of similar companies and their debt to equity mix, their related volatility and the size of their market capitalization. The interim quantitative goodwill impairment test for the Rest of Products reporting unit did not indicate that goodwill was impaired. Annual goodwill impairment test: During fiscal 2019 the Company performed a qualitative analysis of the fair value of its Rest of Products and Duff-Norton reporting units for its annual goodwill impairment testing. The qualitative analysis did not require the use of non-recurring fair value measurements. A similar qualitative analysis was also performed for the Company's STAHL, Magnetek, and Unified Industries indefinite-lived intangible assets. After performing the qualitative analysis, the Company determined that a quantitative analysis was not required for its goodwill and indefinite-lived intangible assets other than for the goodwill of the Duff-Norton reporting unit. The quantitative goodwill impairment test for the Duff-Norton reporting unit required determining the fair value of the unit. The fair value for the Company’s Duff-Norton reporting unit cannot be determined using readily available quoted Level 1 inputs or Level 2 inputs that are observable in active markets. Therefore, the Company used a blended discounted cash flow and market-based valuation model to estimate the fair value of the Duff-Norton reporting unit, using Level 3 inputs. To estimate the fair value of the Duff-Norton reporting unit, the Company used significant estimates and judgmental factors. The key estimates and factors used in the discounted cash flow valuation include revenue growth rates and profit margins based on internal forecasts, terminal value, and the weighted-average cost of capital used to discount future cash flows. In performing the above analysis, the compound annual growth rate for revenue during the first five years of the projections was approximately 5.83% . The terminal value was calculated assuming a projected growth rate of 3.5% after five years. The estimated weighted-average cost of capital for the reporting units was determined to be 12.3% based upon an analysis of similar companies and their debt to equity mix, their related volatility, and the size of their market capitalization. After performing the quantitative analysis, the Company concluded that the goodwill of the Duff-Norton reporting unit was not impaired. Other non-recurring measurements: During fiscal 2019, the Company initiated the process to close its Salem, Ohio facility and moved its operations to other facilities. In doing so the Company incurred $1,473,000 in costs, of which $436,000 relate to severance and other employee termination costs. The costs incurred were calculated at fair value on a non-recurring basis using Level 3 inputs which included expected payments. Fiscal 2018 Non-Recurring Measurements During fiscal 2019 and 2018, the Company terminated certain employees in connection with its overall STAHL integration plan. The Company incurred $5,765,000 in severance and other employee termination costs. The costs incurred were calculated at fair value on a non-recurring basis using Level 3 inputs which included expected payments. Of this, $1,809,000 was unpaid and included within accrued liabilities on the Company's consolidated balance sheets at March 31, 2018. As of March 31, 2019, this has nearly all been paid. During fiscal 2018 the Company performed a qualitative analysis of the fair value of its Rest of Products and Duff-Norton reporting units for its goodwill impairment testing. The qualitative analysis did not require the use of non-recurring fair value measurements. A similar qualitative analysis was also performed for the Company's STAHL and Unified Industries indefinite-lived intangible assets. The Company performed a quantitative analysis to evaluate whether the indefinite-lived intangible assets of Magnetek were impaired. In performing this analysis, a royalty rate of 2.7% and a discount rate of 10.0% was used. See Note 9 for additional discussion on the Company's goodwill impairment assessment and the conclusions reached.

Revenue Recognition (Notes)

Revenue Recognition (Notes)	12 Months Ended

Revenue Recognition, Policy [Policy Text Block]	4. Revenue Recognition Transition In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606) (“ASC 606”). ASC 606 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASC 606 requires the recognition of revenue when control transfers under the terms of the contract to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The standard became effective for the Company on April 1, 2018. As part of the adoption of ASC 606, the Company applied the new standard using the modified retrospective method to contracts not completed at the date of adoption and prior period results have not been retrospectively adjusted to give effect to the adoption of ASC 606. The adoption of this standard did not have a material impact on the timing or amount of revenue or costs recognized by the Company, therefore no cumulative effect or catch up adjustment to the opening balance of retained earnings was recorded. Further, disclosures of what our revenues and costs would have been during fiscal 2019 under legacy U.S. GAAP have not been disclosed as there are no material differences between the reported results under the new standard and those that would have been reported under legacy U.S. GAAP. The core principle under ASC 606 is for revenue to be recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. To achieve this core principle, the Company applies the following five steps: 1) Identifying contracts with customers A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the related payment terms, (ii) the contract has commercial substance, and (iii) the Company determines that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the products and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other available resources, and are distinct in the context of the contract, whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods and services, the Company must apply judgment to determine whether promised goods and services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation. 3) Determine the transaction price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products and services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes. In applying this guidance, the Company also considers whether any significant financing components exist. 4) Allocate the transaction price to the performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. 5) Recognize revenue when or as the Company satisfies a performance obligation The Company determines whether it satisfies performance obligations either over time or at a point in time. Revenue is recognized over time if either 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, 2) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer. Examples of control are using the asset to produce goods or services, enhancing the value of other assets, settling liabilities, and holding or selling the asset. For over time recognition, ASC 606 requires the Company to select a single revenue recognition method for the performance obligation that faithfully depicts the Company’s performance in transferring control of the goods and services. The guidance allows entities to choose between either an input method or an output method to measure progress toward complete satisfaction of a performance obligation. Performance obligations The Company has contracts with customers for standard products and custom engineered products and determines when and how to recognize revenue for each performance obligation based on the nature and type of contract following the five steps above. Revenue from contracts with customers for standard products is recognized when legal title and significant risk and rewards has transferred to the customer, which is generally at the time of shipment. This is the point in time when control is deemed to transfer to the customer. The Company sells standard products to customers utilizing purchase orders. Payment terms for these types of contracts generally require payment within 30-60 days. Each standard product is deemed to be a single performance obligation and the amount of revenue recognized is based on the negotiated price. The transaction price for standard products is based on the price reflected in each purchase order. Sales incentives are offered to customers who purchase standard products and include offers such as volume-based discounts, rebates for priority customers, and discounts for early cash payments. These sales incentives are accounted for as variable consideration included in the transaction price. Accordingly, the Company reduces revenue for these incentives in the period which the sale occurs and is based on the most likely amount method for estimating the amount of consideration the Company expects to receive. These sales incentive estimates are updated each reporting period as additional information becomes available. The Company also sells custom engineered products and services which are contracts that are typically completed within one quarter but can extend beyond one year in duration. For custom engineered products, the transaction price is based upon the price stated in the contract. The Company generally recognizes revenue for custom engineered products upon satisfaction of its performance obligation under the contract which typically coincides with project completion which is when the products and services are controlled by the customer. Control is typically achieved at the later of when legal title and significant risk and rewards have transferred to the customer or the customer has accepted the asset. These contracts often require either up front or installment payments. These types of contracts are generally accounted for as one performance obligation as the products and services are not separately identifiable. The promised services (such as inspection, commissioning, and installation) are essential in order for the delivered product to operate as intended on the customer’s site and the services are therefore highly interrelated with product functionality. Further, while there is no alternative use for most custom engineered products, the Company typically does not have an enforceable right to payment (which must include a reasonable profit margin) for performance completed to date in order to meet the over time revenue recognition criteria. Therefore, under these circumstances the total contract price is recognized at a point in time (when the contract is complete). Variable consideration has not been identified as a significant component of transaction price for custom engineered products and services. Sales and other taxes collected with revenue are excluded from revenue, consistent with the previous revenue standard. Shipping and handling costs incurred prior to shipment are considered activities required to fulfill the Company’s promise to transfer goods, and do not qualify as a separate performance obligation. Additionally, the Company offers standard warranties which are typically 12 months in duration for standard products and 24 to 36 months for custom engineered products. These types of warranties are included in the purchase price of the product and are deemed to be assurance-type warranties which are not accounted for as a separate performance obligation. Other performance obligations included in a contract (such as drawings, owner’s manuals, and training services) are immaterial in the context of the contract and are not recognized as a separate performance obligation. Reconciliation of contract balances The Company records a contract liability when cash is received prior to recording revenue. Some standard contracts require a down payment while most custom engineered contracts require installment payments. Installment payments for the custom engineered contracts typically require a portion due at inception while the remaining payments are due upon completion of certain performance milestones. For both types of contracts, these contract liabilities, referred to as customer advances, are recorded at the time payment is received and are included in Accrued liabilities on the Consolidated Balance Sheets. When the related performance obligation is satisfied, the contract liability is released into revenue. The following table illustrates the balance and related activity for customer advances in fiscal 2019 (in thousands): Customer advances (contract liabilities) March 31, 2018, beginning balance $ 15,909 Additional customer advances received 39,868 Revenue recognized from customer advances included in the beginning balance (15,909 ) Other revenue recognized from customer advances (27,247 ) Customer deposits on Sold Businesses (Note 3) (139 ) Other (1) (981 ) March 31, 2019, ending balance $ 11,501 (1) Other includes the impact of foreign currency translation As of March 31, 2019 , recognized revenue prior to the right to invoice the customer in accordance with the contract terms was not material. As such, there are no material contract asset balances, which represent revenue in excess of billings, as of the date of adoption of ASC 606 or as of March 31, 2019 . Disaggregated revenue In accordance with ASC 606, the Company is required to disaggregate revenue into categories that depict how economic factors affect the nature, amount, timing and uncertainty of revenue and cash flows. The following table illustrates the disaggregation of revenue by product grouping for the year ending March 31, 2019 (in thousands): Twelve Months Ended Net Sales by Product Grouping March 31, 2019 Industrial Products $ 379,845 Crane Solutions 379,836 Engineered Products 82,406 All other 34,195 Total $ 876,282 Industrial products include: manual chain hoists, electrical chain hoists, rigging/ clamps, industrial winches, hooks, shackles, and other forged attachments. Crane solutions products include: wire rope hoists, drives and controls, crane kits and components, and workstations. Engineered products include: linear and mechanical actuators, lifting tables, rail projects, and actuations systems. The All other product grouping includes the Sold Businesses. Practical expedients Incremental costs to obtain a contract incurred by the Company primarily relate to sales commissions for contracts with a duration of one year or less. Therefore, these costs are expensed as incurred and are recorded in Selling Expenses on the Consolidated Statements of Operations. Unsatisfied performance obligations for contracts with an expected length of one year or less are not disclosed. Further, revenue from contracts with customers do not include a significant financing component as payment is generally expected within one year from when the performance obligation is controlled by the customer.

Marketable Securities [Abstract]
Marketable Securities	Marketable Securities and Other Investments In accordance with ASU 2016-01 "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," adopted by the Company on April 1, 2018, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounts) are measured at fair value through earnings. There is no longer an available-for-sale classification for equity securities or certain mutual funds (such as bond funds and fixed-income funds) with readily determinable fair values. As such, the Company's marketable securities (both equity and fixed-income securities) are no longer classified as available-for-sale securities. The Company's marketable securities are still recorded at their fair values, however, gains and losses are realized within Investment (income) loss on the Consolidated Statements of Operations. The Company adopted this standard on a modified retrospective basis. A cumulative effect adjustments of $888,000 was recorded on April 1, 2018 to the beginning balance of Retained Earnings with an offset to Accumulated Other Comprehensive Loss. The impact on earnings was an unrealized loss of $183,000 in the year ended March 31, 2019. Marketable securities are carried as long-term assets since they are held for the settlement of the Company’s general and products liability insurance claims filed through CM Insurance Company, Inc. ("CMIC"), a wholly owned captive insurance subsidiary. The marketable securities are not available for general working capital purposes. Net realized gains related to sales of marketable securities were $201,000 , $0 , and $161,000 in fiscal years 2019 , 2018 , and 2017 , respectively, and are included in Investment (income) loss in the Consolidated Statements of Operations. The following is a summary of available-for-sale securities at March 31, 2018 (in thousands, prior to the adoption of ASU 2016-01): Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Marketable securities $ 7,149 $ 588 $ 64 $ 7,673 The aggregate fair value of investments and unrealized losses on available-for-sale securities in an unrealized loss position at March 31, 2018 are as follows (in thousands, prior to the adoption of ASU 2016-01): Aggregate Fair Value Unrealized Losses Securities in a continuous loss position for less than 12 months $ 1,859 $ 26 Securities in a continuous loss position for more than 12 months 1,285 38 $ 3,144 $ 64 Net unrealized gains included in the balance sheet amounted to $524,000 at March 31, 2018 . The amounts, net of related deferred tax liabilities of $110,000 at March 31, 2018 , are reflected as a component of accumulated other comprehensive loss within shareholders’ equity. On December 21, 2017, the Company purchased a 49% ownership interest in Eastern Morris Cranes Company Limited ("EMC"), a limited liability company organized and existing under the laws and regulations of the Kingdom of Saudi Arabia, for $3,359,000 . This represents an equity investment in a strategic customer of STAHL serving the Kingdom of Saudi Arabia. The investment value was increased for the Company's ownership percentage of income earned by EMC during the fiscal year, offset by changes in foreign currency revaluation. Investment income for the Company's ownership interest in EMC was $449,000 in the twelve months ended March 31, 2019 and was not material for the twelve months ended March 31, 2018. The investment's carrying value as of March 31, 2019 is $3,602,000 and has been accounted for as an equity method investment. It is presented in other assets in the Consolidated Balance Sheets. The March 31, 2019 trade accounts receivable balance due from EMC is $2,986,000 and is comprised of amounts due for the sale of goods and services in the ordinary course of business.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets As discussed in Note 2, goodwill is not amortized but is tested for impairment at least annually, in accordance with the provisions of ASC Topic 350-20-35-1. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. The fair value of a reporting unit is determined using a discounted cash flow methodology. The Company’s reporting units are determined based upon whether discrete financial information is available and reviewed regularly, whether those units constitute a business, and the extent of economic similarities and interdependencies between those reporting units for purposes of aggregation. The Company’s reporting units identified under ASC Topic 350-20-35-33 are at the component level, or one level below the operating segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting – Disclosure.” At March 31, 2018, the Company had four reporting units. Two of these reporting units were sold in connection with the Sold Businesses described in Note 3. As such, the Company has two reporting units as of March 31, 2019 , both of which have goodwill. The Duff-Norton reporting unit (which designs, manufactures, and sources mechanical and electromechanical actuators and rotary unions) had goodwill of $9,611,000 and $9,721,000 at March 31, 2019 and 2018 , respectively, and the Rest of Products reporting unit (representing the hoist, chain, and forgings, digital power control systems, and distribution businesses) had goodwill of $313,205,000 and $337,713,000 at March 31, 2019 and 2018 , respectively. Fiscal 2019 Interim Impairment Test During the first quarter of fiscal 2019, the Company classified the assets and liabilities of certain businesses as held for sale. These businesses were sold later in the year which is described in Note 3. As a result of this classification, the Company determined an indicator of impairment existed and was required to perform an interim goodwill impairment test on the Rest of Products goodwill reporting unit. The net assets of the Rest of Products reporting unit were measured on a non-recurring basis in order to perform a quantitative goodwill impairment test. The interim quantitative goodwill impairment test for Rest of Products did not indicate that goodwill was impaired. The held for sale classification described above further required the Company to assign a portion of goodwill to the business that was a part of the Rest of Products reporting unit based on its relative fair value and to record the assets and liabilities of the businesses held for sale at the lower of their carrying amount or fair value less cost to sell. Based on this analysis, the Company recorded a $6,174,000 goodwill impairment charge at the time the businesses were classified as held for sale. Fiscal 2019 Annual Goodwill and Intangible Asset Impairment Test When we evaluate the potential for goodwill impairment, we assess a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for our products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value or if economic or other business factors indicate that the fair value of our reporting units may have declined since our last quantitative test, we proceed to a quantitative impairment test. To perform the quantitative impairment test, the Company uses the discounted cash flow method to estimate the fair value of the reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating profit margins and cash flows, the terminal growth rate, and the discount rate. The Company projects revenue growth rates, operating margins and cash flows based on each reporting unit's current business, expected developments, and operational strategies over a five-year period. In estimating the terminal growth rates, the Company considers its historical and projected results, as well as the economic environment in which its reporting units operate. The discount rates utilized for each reporting unit reflect the Company's assumptions of marketplace participants' cost of capital and risk assumptions, both specific to the reporting unit and overall in the economy. We performed the qualitative assessment as of February 28, 2019 and determined that the quantitative goodwill impairment test was not required for the Rest of Products reporting unit. The qualitative assessment for the Duff-Norton reporting unit indicated that a quantitative test should be performed. Based on results of the quantitative impairment test for the Duff-Norton reporting unit, the Company determined the fair value was not less than its carrying value. In accordance with ASC Topic 350-30-35, indefinite-lived intangible assets that are not subject to amortization shall be tested for impairment annually or more frequently if events or circumstances indicate that it is more likely than not that an asset is impaired. Similar to goodwill, we first assess various qualitative factors in the analysis. If, after completing this assessment, it is determined that it is more likely than not that the fair value of an indefinite-lived intangible asset is greater than its carrying value, we conclude that the indefinite-lived intangible asset is not impaired. If, after completing this assessment, it is determined that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value or if economic or other business factors indicate that the fair value of our indefinite-lived intangible assets may have declined since our last quantitative test, the Company performs a new quantitative test. The methodology used to value trademarks is the relief from royalty method. The recorded book value of these trademarks in excess of the calculated fair value triggers an impairment. The key estimate used in this calculation consists of an overall royalty rate applied to the sales covered by the trademark. After performing a qualitative assessment as of February 28, 2019 , it was determined that the trademarks were not impaired. A summary of changes in goodwill during the years ended March 31, 2019 and 2018 is as follows: Balance at April 1, 2017 $ 319,299 STAHL measurement period adjustment $ 64 Currency translation 28,071 Balance at March 31, 2018 $ 347,434 Interim Goodwill Impairment (6,174 ) Currency translation (18,444 ) Balance at March 31, 2019 $ 322,816 Goodwill is recognized net of accumulated impairment losses of $113,174,000 and $107,000,000 as of March 31, 2019 and 2018 , respectively. There was $6,174,000 of goodwill impairment losses recorded in fiscal 2019 related to the interim goodwill impairment test described above and none recorded in 2018 and 2017 . Identifiable intangible assets at March 31, 2019 are summarized as follows (in thousands): Gross Carrying Amount Accumulated Amortization Net Trademark $ 6,212 $ (4,138 ) $ 2,074 Indefinite-lived trademark 46,981 — 46,981 Customer relationships 182,328 (35,344 ) 146,984 Acquired technology 46,715 (10,412 ) 36,303 Other 3,254 (2,656 ) 598 Balance at March 31, 2019 $ 285,490 $ (52,550 ) $ 232,940 Identifiable intangible assets at March 31, 2018 were as follows (in thousands): Gross Carrying Amount Accumulated Amortization Net Trademark $ 5,875 $ (3,299 ) $ 2,576 Indefinite-lived trademark 48,874 — 48,874 Customer relationships 199,045 (27,887 ) 171,158 Acquired technology 46,898 (7,436 ) 39,462 Other 3,936 (2,242 ) 1,694 Balance at March 31, 2018 $ 304,628 $ (40,864 ) $ 263,764 Customer relationships with a gross carrying amount of $2,815,000 and accumulated amortization of $957,000 were written off during fiscal 2019, in connection with the loss on the Sold Businesses discussed in Note 3. Further, other intangible assets with a gross carrying amount of $226,000 and accumulated amortization of $211,000 were also written off during fiscal 2019 as a result of the loss on the Sold Businesses. The Company’s intangible assets that are considered to have finite lives are amortized over the period in which the assets are expected to generate future cash flows. Identifiable intangible assets acquired in a business combination are amortized over their estimated useful lives. The weighted-average amortization periods are 14 years for trademarks, 18 years for customer relationships, 18 years for acquired technology, 6 years for other, and 18 years in total. Trademarks with a book value of $46,981,000 have an indefinite useful life and are therefore not being amortized. Total amortization expense was $14,900,000 , $15,552,000 , and $8,105,000 for fiscal 2019 , 2018 , and 2017 , respectively. Based on the current amount of intangible assets, the estimated amortization expense for each of the succeeding five years is expected to be approximately $13,500,000 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company uses derivative instruments to manage selected foreign currency and interest rate exposures. The Company does not use derivative instruments for speculative trading purposes. All derivative instruments must be recorded on the balance sheet at fair value. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is recorded as accumulated other comprehensive gain (loss), or “AOCL,” and is reclassified to earnings when the underlying transaction has an impact on earnings. The ineffective portion of changes in the fair value of the foreign currency forward agreements is reported in foreign currency exchange loss (gain) in the Company’s consolidated statement of operations. The ineffective portion of changes in the fair value of the interest rate swap agreements is reported in interest expense. For derivatives not designated as cash flow hedges, all changes in market value are recorded as a foreign currency exchange (gain) loss in the Company’s consolidated statements of operations. The cash flow effects of derivatives are reported within net cash provided by operating activities. The Company is exposed to credit losses in the event of non-performance by the counterparties on its financial instruments. The counterparties have investment grade credit ratings. The Company anticipates that these counterparties will be able to fully satisfy their obligations under the contracts. The Company has derivative contracts with four counterparties as of March 31, 2019 . The Company's agreements with its counterparties contain provisions pursuant to which the Company could be declared in default of its derivative obligations. As of March 31, 2019 , the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of March 31, 2019 , it could have been required to settle its obligations under these agreements at amounts which approximate the March 31, 2019 fair values reflected in the table below. During the year ended March 31, 2019 , the Company was not in default of any of its derivative obligations. As of March 31, 2019 and 2018 , the Company had no derivatives designated as net investments or fair value hedges in accordance with ASC Topic 815, “Derivatives and Hedging.” The Company has cross currency swap agreements that are designated as cash flow hedges to hedge changes in the value of intercompany loans to a foreign subsidiary due to changes in foreign exchange rates. These intercompany loans are related to the acquisition of STAHL. The notional amount of these derivatives is $198,260,000 , and all of the contracts mature by January 31, 2022. From its March 31, 2019 balance of AOCL, the Company expects to reclassify approximately $1,276,000 out of AOCL, and into foreign currency exchange loss (gain), during the next 12 months based on the contractual payments due under these intercompany loans. The Company has foreign currency forward agreements in place to offset changes in the value of other intercompany loans to foreign subsidiaries due to changes in foreign exchange rates. The notional amount of these derivatives is $3,461,000 and all of the contracts mature by June 30, 2019. These contracts are marked to market each balance sheet date and are not designated as hedges. The Company has foreign currency forward agreements that are designated as cash flow hedges to hedge a portion of forecasted inventory purchases denominated in foreign currencies. The notional amount of those derivatives is $11,185,000 and all contracts mature by March 31, 2020. From its March 31, 2019 balance of AOCL, the Company expects to reclassify approximately $1,000 out of AOCL during the next 12 months based on the underlying transactions of the sales of the goods purchased. The Company's policy is to maintain a capital structure that is comprised of 50-70% of fixed rate long-term debt and 30-50% of variable rate long-term debt. The Company has two interest rate swap agreements in which the Company receives interest at a variable rate and pays interest at a fixed rate. These interest rate swap agreements are designated as cash flow hedges to hedge changes in interest expense due to changes in the variable interest rate of the senior secured term loan. The amortizing interest rate swaps mature by December 31, 2023 and have a total notional amount of $197,160,000 as of March 31, 2019 . The effective portion of the changes in fair values of the interest rate swaps is reported in AOCL and will be reclassified to interest expense over the life of the swap agreements. From its March 31, 2019 balance of AOCL, the Company expects to reclassify approximately $565,000 out of AOCL, and into interest expense, during the next 12 months.

The Facilities consist of a Revolving Facility ("Revolver") in the amount of $100,000,000 and a $445,000,000 1st Lien Term Loan ("Term Loan"). The Term Loan has a seven -year term maturing in 2024 and the Revolver has a five -year term maturing in 2022. At March 31, 2019 the Company has not drawn from the Revolver. The key terms of the agreement are as follows: • Term Loan: An aggregate $445,000,000 1st Lien Term Loan which requires quarterly principal amortization of 0.25% with the remaining principal due at maturity date. In addition, if the Company has Excess Cash Flow ("ECF") as defined in the Credit Agreement, the ECF Percentage of the Excess Cash Flow for such fiscal year minus optional prepayment of the Loans (except prepayments of Revolving Loans that are not accompanied by a corresponding permanent reduction of Revolving Commitments) pursuant to Section 2.10(a) of the Credit Agreement other than to the extent that any such prepayment is funded with the proceeds of Funded Debt, shall be applied toward the prepayment of the Term Loan. The ECF Percentage is defined as 50% stepping down to 25% or 0% based on the Secured Leverage Ratio as of the last day of the fiscal year. • Revolver: An aggregate $100,000,000 secured revolving facility which includes sublimits for the issuance of standby letters of credit, swingline loans and multi-currency borrowings in certain specified foreign currencies. • Fees and Interest Rates: Commitment fees and interest rates are determined on the basis of either a Eurocurrency rate or a Base rate plus an applicable margin based upon the Company's Total Leverage Ratio (as defined in the Credit Agreement). • Prepayments: Provisions permitting a Borrower to voluntarily prepay either the Term Loan or Revolver in whole or in part at any time, and provisions requiring certain mandatory prepayments of the Term Loan or Revolver on the occurrence of certain events which will permanently reduce the commitments under the Credit Agreement, each without premium or penalty, subject to reimbursement of certain costs of the Lenders. A prepayment premium of 1% of the principal amount of the First Lien Term Loans is required if the prepayment is associated with a Repricing Transaction and it were to occur within the first twelve months. • Covenants: Provisions containing covenants required of the Corporation and its subsidiaries including various affirmative and negative financial and operational covenants. The key financial covenant is triggered only on any date when any Extension of Credit under the Revolving Facility is outstanding (excluding any Letters of Credit) (the “Covenant Trigger”), and permits the Total Leverage Ratio for the Reference Period ended on such date to not exceed (i) 4.50:1.00 as of any date of determination prior to December 31, 2017, (ii) 4.00:1.00 as of any date of determination on December 31, 2017 and thereafter but prior to December 31, 2018, (iii) 3.50:1.00 as of any date of determination on December 31, 2018 and thereafter but prior to December 31, 2019 and (iv) 3.00:1.00 as of any date of determination on December 31, 2019 and thereafter. As there is no amount drawn on the Revolver as of March 31, 2019 the requirement to comply with the covenant is not triggered. Had we been required to determine the covenant ratio we would have been in compliance with the covenant provisions as of March 31, 2019 and 2018 . The Facility is secured by all U.S. inventory, receivables, equipment, real property, certain subsidiary stock (limited to 65% of non-U.S. subsidiaries) and intellectual property. The Credit Agreement allows, but limits our ability to pay dividends. On February 26, 2018, the Company amended the Credit Agreement (known as the "Amended Credit Agreement"). The Amended Credit Agreement has the same terms mentioned above except for a reduction in interest rates. The applicable rate for the repriced term loan was reduced from 3.00% to 2.50% . The Company accounted for the Amended Credit Agreement as a debt modification, therefore, debt repricing fees incurred in fiscal 2018 were expensed as General and Administrative expenses and the deferred financing fees incurred as part of the Credit Agreement (discussed below) remain unchanged. The outstanding balance of the Term Loan was $310,463,000 and $375,463,000 as of March 31, 2019 and 2018 , respectively. The Company made $65,000,000 of principal payment on the Term Loan during fiscal 2019 and $57,037,000 of principal payment on the Term Loan during fiscal 2018 . The Company is obligated to make $4,450,000 of principal payments over the next 12 months, however, plans to pay down $65,000,000 in total. This amount has been recorded within the current portion of long-term debt on the Company's Consolidated Balance Sheet with the remaining balance recorded as long-term debt. There was $0 outstanding on the Revolving Credit Facility and $17,329,000 outstanding letters of credit as of March 31, 2019 . The outstanding letters of credit at March 31, 2019 consisted of $1,236,000 in commercial letters of credit and $16,093,000 of standby letters of credit. The gross balance of deferred financing costs on the term loan was $14,690,000 as of March 31, 2019 and 2018 . The accumulated amortization balances were $4,547,000 and $2,447,000 as of March 31, 2019 and 2018 , respectively. The gross balance of deferred financing costs associated with the Revolving Credit Facility is included in Other assets is $2,789,000 as of March 31, 2019 and March 31, 2018 . The accumulated amortization balance is $1,209,000 and $651,000 as of March 31, 2019 and March 31, 2018 respectively. These balances are classified in Other assets since no funds were drawn on the Revolving Credit Facility in fiscal 2019 and 2018 . The principal payments obligated to be made as of March 31, 2019 on the Term Loan are as follows: 2020 4,450 2021 4,450 2022 4,450 2023 4,450 2024 292,663 Thereafter — $ 310,463 Non-U.S. Lines of Credit and Loans Unsecured and uncommitted lines of credit are available to meet short-term working capital needs for certain of our subsidiaries operating outside of the U.S. The lines of credit are available on an offering basis, meaning that transactions under the line of credit will be on such terms and conditions, including interest rate, maturity, representations, covenants, and events of default, as mutually agreed between our subsidiaries and the local bank at the time of each specific transaction. As of March 31, 2019 , unsecured credit lines totaled approximately $2,468,000 , of which $0 was drawn. In addition, unsecured lines of $16,437,000 were available for bank guarantees issued in the normal course of business of which $10,275,000 was utilized.

Retirement Benefits [Abstract]
Pensions and Other Benefit Plans	Pensions and Other Benefit Plans The Company provides retirement plans, including defined benefit and defined contribution plans, and other postretirement benefit plans to certain employees. The Company applies ASC Topic 715 “Compensation – Retirement Benefits,” which required the recognition in pension and other postretirement benefits obligations and accumulated other comprehensive income of actuarial gains or losses, prior service costs or credits and transition assets or obligations that had previously been deferred. This statement also requires an entity to measure a defined benefit postretirement plan’s assets and obligations that determine its funded status as of the end of the fiscal year. Pension Plans The Company provides defined benefit pension plans to certain employees. The Company uses March 31 as the measurement date. The following provides a reconciliation of benefit obligation, plan assets, and funded status of the plans: March 31, 2019 2018 Change in benefit obligation: Benefit obligation at beginning of year $ 462,284 $ 471,871 Service cost 1,078 2,580 Interest cost 15,526 16,488 Actuarial (gain) loss 4,074 (2,467 ) Benefits paid (27,068 ) (35,888 ) Settlement — (65 ) Curtailment — (4,082 ) Foreign exchange rate changes (9,497 ) 13,847 Benefit obligation at end of year $ 446,397 $ 462,284 Change in plan assets: Fair value of plan assets at beginning of year $ 326,745 $ 321,440 Actual gain (loss) on plan assets 11,333 29,930 Employer contribution 11,018 11,211 Benefits paid (27,068 ) (35,888 ) Settlement — (65 ) Foreign exchange rate changes (126 ) 117 Fair value of plan assets at end of year $ 321,902 $ 326,745 Funded status $ (124,495 ) $ (135,539 ) Unrecognized actuarial loss 73,836 65,832 Net amount recognized $ (50,659 ) $ (69,707 ) Amounts recognized in the consolidated balance sheets are as follows: March 31, 2019 2018 Other assets $ 6,424 $ — Accrued liabilities (3,546 ) (3,814 ) Other non-current liabilities (127,373 ) (131,725 ) Accumulated other comprehensive loss, before tax 73,836 65,832 Net amount recognized $ (50,659 ) $ (69,707 ) Other assets are presented separately in fiscal 2019 as one of the Company's U.S. plans is now overfunded, therefore, it is no longer presented as a liability. In fiscal 2020, an estimated net loss of $2,275,000 and no prior service costs for the defined benefit pension plans will be amortized from accumulated other comprehensive loss to net periodic benefit cost. Net periodic pension cost included the following components: 2019 2018 2017 Service costs—benefits earned during the period $ 1,078 $ 2,580 $ 1,779 Interest cost on projected benefit obligation 15,526 16,488 16,648 Expected return on plan assets (18,454 ) (21,483 ) (22,428 ) Net amortization 2,339 3,083 3,190 Curtailment — 5 — Settlement — — 247 Other — 17 (57 ) Net periodic pension cost (benefit) $ 489 $ 690 $ (621 ) The Company adopted ASU 2017-07 in the first quarter of fiscal 2019. The service cost component of net periodic benefit cost above is recorded in Cost of products sold, Selling expense, and General and administrative expenses within the Consolidated Statements of Operations, while the remaining components are recorded to Other (income) expense, net. The prior year amounts have been reclassified to provide comparable presentation in line with the guidance in ASU 2017-07 based on amounts previously disclosed for the various components of net periodic pension cost (benefit). Information for pension plans with a projected benefit obligation in excess of plan assets is as follows: March 31, 2019 2018 Projected benefit obligation $ 395,202 $ 462,284 Fair value of plan assets 264,211 326,745 Information for pension plans with an accumulated benefit obligation in excess of plan assets is as follows: March 31, 2019 2018 Accumulated benefit obligation $ 389,509 $ 457,323 Fair value of plan assets 264,211 326,745 Unrecognized gains and losses are amortized through March 31, 2019 on a straight-line basis over the average remaining service period of active participants. Starting in fiscal 2016, the Company changed the amortization period of its largest plan to the average remaining lifetime of inactive participants, as a significant portion of the plan population is now inactive. This change increases the amortization period of the unrecognized gains and losses. The weighted-average assumptions in the following table represent the rates used to develop the actuarial present value of the projected benefit obligation for the year listed and also net periodic pension cost for the following year: 2019 2018 2017 Discount rate 3.42 % 3.49 % 3.65 % Expected long-term rate of return on plan assets 5.77 % 6.77 % 7.23 % Rate of compensation increase on active plans 0.61 % 0.39 % 0.39 % The expected rates of return on plan asset assumptions are determined considering long-term historical averages and real returns on each asset class. The Company’s retirement plan target and actual asset allocations are as follows: Target Actual 2020 2019 2018 Equity securities 40% - 35% 35% 46% Fixed income 60% - 65% 65% 54% Total plan assets 100% 100% 100% The Company has an investment objective for domestic pension plans to adequately provide for both the growth and liquidity needed to support all current and future benefit payment obligations. The Company's policy is to de-risk the portfolio by increasing liability-hedging investments as the pension liability funded status increases, which is known as the glide path method. Within the table above, cash equivalents are categorized as fixed income as they earn lower returns than equity securities which includes alternative real estate funds (shown in the fair value tables below). The Company’s funding policy with respect to the defined benefit pension plans is to contribute annually at least the minimum amount required by the Employee Retirement Income Security Act of 1974 (ERISA). Additional contributions may be made to minimize PBGC premiums. The Company expects to contribute approximately $11,094,000 to its pension plans in fiscal 2020 . Information about the expected benefit payments for the Company’s defined benefit plans is as follows: 2020 $ 27,018 2021 26,970 2022 27,268 2023 27,622 2024 27,568 2025-2029 134,589 Postretirement Benefit Plans The Company sponsors a defined benefit other postretirement health care plan that provide medical and life insurance coverage to certain U.S. retirees and their dependents of one of its subsidiaries. Prior to the acquisition of this subsidiary, the Company did not sponsor any postretirement benefit plans. The Company pays the majority of the medical costs for certain retirees and their spouses who are under age 65 . For retirees and dependents of retirees who retired prior to January 1, 1989, and are age 65 or over, the Company contributes 100% toward the American Association of Retired Persons (“AARP”) premium frozen at the 1992 level. For retirees and dependents of retirees who retired after January 1, 1989, the Company contributes $35 per month toward the AARP premium. The life insurance plan is noncontributory. The Company’s postretirement health benefit plans are not funded. The following sets forth a reconciliation of benefit obligation and the funded status of the plan: March 31, 2019 2018 Change in benefit obligation: Benefit obligation at beginning of year $ 3,284 $ 4,111 Interest cost 92 126 Actuarial gain (778 ) (642 ) Benefits paid (250 ) (311 ) Benefit obligation at end of year $ 2,348 $ 3,284 Funded status $ (2,348 ) $ (3,284 ) Unrecognized actuarial gain (1,282 ) (660 ) Net amount recognized $ (3,630 ) $ (3,944 ) Amounts recognized in the consolidated balance sheets are as follows: March 31, 2019 2018 Accrued liabilities $ (326 ) $ (449 ) Other non-current liabilities (2,022 ) (2,835 ) Accumulated other comprehensive gain, before tax (1,282 ) (660 ) Net amount recognized $ (3,630 ) $ (3,944 ) In fiscal 2020 , an estimated gain of $161,000 for the defined benefit postretirement health care plans will be amortized from accumulated other comprehensive loss to net periodic benefit cost. In fiscal 2019 , net periodic postretirement benefit cost included the following: Year Ended March 31, 2019 2018 2017 Interest cost $ 92 $ 126 $ 152 Net amortization (156 ) (5 ) — Net periodic postretirement benefit cost $ (64 ) $ 121 $ 152 For measurement purposes, healthcare costs are assumed to increase 6.00% in fiscal 2020 , grading down over time to 5.0% in five years. The discount rate used in determining the accumulated postretirement benefit obligation was 3.63% and 3.75% as of March 31, 2019 and 2018 , respectively. Information about the expected benefit payments for the Company’s postretirement health benefit plans is as follows: 2020 $ 326 2021 302 2022 273 2023 252 2024 233 2025-2029 829 Assumed medical claims cost trend rates have an effect on the amounts reported for the health care plans. A one-percentage point change in assumed health care cost trend rates would have the following effects One Percentage Point Increase One Percentage Point Decrease Effect on total of service and interest cost components $ 4 $ (3 ) Effect on postretirement obligation 103 (94 ) The Company has collateralized split-dollar life insurance arrangements with two of its former officers. Under these arrangements, the Company pays certain premium costs on life insurance policies for the former officers. Upon the later of the death of the former officer and their spouse, the Company will receive all of the premiums paid to-date. The net periodic pension cost for fiscal 2019 was $178,000 and the liability at March 31, 2019 is $4,543,000 with $4,406,000 included in other non-current liabilities and $137,000 included in accrued liabilities in the consolidated balance sheet. The cash surrender value of the policies is $3,207,000 and $3,060,000 at March 31, 2019 and 2018 , respectively. The balance is included in other assets in the consolidated balance sheet. Other Benefit Plans The Company also sponsors defined contribution plans covering substantially all domestic employees and certain international employees. Participants may elect to contribute basic contributions. These plans provide for employer contributions based on employee eligibility and participation. The Company recorded a charge for such contributions of approximately $5,260,000 , $4,198,000 , and $3,543,000 for the years ended March 31, 2019 , 2018 , and 2017 , respectively which are included in Cost of Products Sold, Selling Expenses, and General and Administrative Expenses within the Consolidated Statements of Operations. The Company expects its contributions for the defined contribution plans in future years to remain comparable to its fiscal 2019 contributions. Fair Values of Plan Assets The Company classified its investments within the categories of equity securities, fixed income securities, alternative real estate, and cash equivalents, as the Company’s management bases its investment objectives and decisions from these four categories. The Company’s investment policy is to use its glide-path method to de-risk the portfolio by increasing liability-hedging investments as the pension liability funded status increases. The fair values of the Company’s defined benefit plans’ consolidated assets by asset category as of March 31 were as follows: March 31, 2019 2018 Asset categories: Equity securities $ 103,017 $ 136,777 Fixed income securities 205,957 174,359 Alternative real estate 9,978 13,230 Cash equivalents 2,950 2,379 Total $ 321,902 $ 326,745 The fair values of our defined benefit plans’ consolidated assets were determined using the fair value hierarchy of inputs described in Note 5. The fair values by category of inputs as of March 31, 2019 and March 31, 2018 were as follows: Measured at NAV (1) Quoted Prices in Active Markets for Identical Assets Significant other observable Inputs Significant unobservable Inputs As of March 31, 2019: (Level 1) (Level 2) (Level 3) Total Asset categories: Equity securities $ 43,314 $ 59,703 $ — $ — $ 103,017 Fixed income securities 45,713 602 153,941 5,701 205,957 Alternative real estate 7,161 2,817 — — 9,978 Cash equivalents — 2,950 — — 2,950 Total $ 96,188 $ 66,072 $ 153,941 $ 5,701 $ 321,902 (1) Reflects the net asset value (NAV) practical expedient used to approximate fair value. Measured at NAV Quoted Prices in Active Markets for Identical Assets Significant other observable Inputs Significant unobservable Inputs As of March 31, 2018: (Level 1) (Level 2) (Level 3) Total Asset categories: Equity securities $ 58,433 $ 78,344 $ — $ — $ 136,777 Fixed income securities 34,620 — 121,271 18,468 174,359 Alternative real estate 8,945 4,285 — — 13,230 Cash equivalents — 2,379 — — 2,379 Total $ 101,998 $ 85,008 $ 121,271 $ 18,468 $ 326,745 During fiscal 2019, the Company liquidated a portion of fixed income securities categorized as level 3 in the prior year. These funds were reinvested in fixed income securities categorized as level 1 and level 2 as of March 31, 2019. A portion of these funds are valued using the NAV practical expedient as the fair value is not publicly available. The Company also sold a portion of equity securities categorized as level 1 in the prior year. These funds were reinvested in fixed income funds categorized as level 2 as of March 31, 2019. Level 1 securities consist of mutual funds with quoted market prices. The Level 2 fixed income securities are investments in a combination of funds whose underlying investments are in a variety of fixed income securities including foreign and domestic corporate bonds, securities issued by the U.S. government, U.S. and foreign government obligations, and other similar fixed income investments. The fair values of the underlying investments in these funds are generally based on independent broker dealer bids, or by comparison to other debt securities having similar durations, yields, and credit ratings. The fair values of these funds are determined based on their net asset values which are published daily. We are not aware of any significant restrictions on the issuances or redemption of shares of these funds Fair value of Level 3 fixed income securities at the beginning of the year was $18,468,000 . During fiscal 2019 fixed income securities earned investment return of $198,000 and had disbursements of $12,965,000 , which includes liquidations, resulting in an ending balance of $5,701,000 . These fixed income securities consist primarily of insurance contracts which are carried at their liquidation value based on actuarial calculations and the terms of the contracts. Significant inputs in determining the fair value for these contracts include company contributions, contract disbursements, and stated interest rates. Gains and losses on these contracts are recognized as part of net periodic pension cost and recorded as part of cost of sales, selling, or general and administrative expense.

Earnings Per Share [Abstract]
Earnings Per Share and Stock Plans	Earnings per Share and Stock Plans Earnings per Share The Company calculates earnings per share in accordance with ASC Topic 260, “Earnings per Share.” Basic earnings per share exclude any dilutive effects of options, warrants, and convertible securities. Diluted earnings per share include any dilutive effects of stock options, unvested restricted stock units, unvested performance shares, and unvested restricted stock. Stock options and performance shares with respect to 128,000 and 340,000 common shares were not included in the computation of diluted earnings per share for fiscal 2019 and 2018 , respectively, because they were antidilutive. For the years ended March 31, 2019 and 2018, an additional 153,000 and 127,000 , respectively, in contingently issuable shares were not included in the computation of diluted earnings per share because a performance condition had not yet been met. The following table sets forth the computation of basic and diluted earnings per share (share data presented in thousands): Year Ended March 31, Numerator for basic and diluted earnings per share: 2019 2018 2017 Net income $ 42,577 $ 22,065 $ 8,984 Denominators: Weighted-average common stock outstanding— denominator for basic EPS 23,276 22,841 20,591 Effect of dilutive employee stock options, RSU's and performance shares 384 494 297 Adjusted weighted-average common stock outstanding and assumed conversions— denominator for diluted EPS 23,660 23,335 20,888 The weighted-average common stock outstanding shown above is net of unallocated ESOP shares (see Note 14). During fiscal 2018, the Company adopted ASU No. 2016-09, "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" (ASU No. 2016-09). Among other modifications to accounting for stock based compensation, this ASU requires that assumed proceeds from excess tax benefits and deficiencies are no longer included in the calculation of weighted-average diluted common stock outstanding and are recorded as income tax expense or benefit in the statement of operations. Refer to Note 17 for the impact the adoption had on the Company's financial statements. During fiscal 2017, the Company entered into an agreement to sell in aggregate 2,273,000 shares of Common Shares to the following purchasers: Adage Capital Management, LP; Heights Capital Management, Inc.; and UBS O'Connor LLC. The sale of the shares closed on January 30, 2017 at a price per Common Share of $22.00 , generating gross proceeds of approximately $50,000,000 . The purchase agreement for the shares requires the Company to file an initial registration statement registering the common shares issued to the purchasers for resale. The filing of the registration statement was completed and declared effective on April 28, 2017. Stock Plans The Company records stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation,” applying the modified prospective method. This Statement requires all equity-based payments to employees, including grants of employee stock options, to be recognized in the statement of earnings based on the grant date fair value of the award. Under the modified prospective method, the Company is required to record equity-based compensation expense for all awards granted after the date of adoption and for the unvested portion of previously granted awards outstanding as of the date of adoption. Prior to the adoptions of the 2010 Long Term Incentive Plan, the Company maintained several different stock plans, specifically: 1995 Incentive Stock Option Plan, Non-Qualified Stock Option Plan, Restricted Stock Plan and 2006 Long Term Incentive Plan, collectively referred to as the “Prior Stock Plans.” The specifics of each of these plans are discussed below. Stock based compensation expense was $6,198,000 , $5,586,000 , and $5,914,000 for fiscal 2019 , 2018 , and 2017 , respectively. Stock compensation expense is included in cost of products sold, selling, and general and administrative expenses depending on the nature of the service of the employee receiving the award. The Company recognizes expense for all share–based awards over the service period, which is the shorter of the period until the employees’ retirement eligibility dates or the service period for the award, for awards expected to vest. Accordingly, expense is generally reduced for estimated forfeitures. ASC Topic 718 requires forfeitures to be estimated at the time of grant and revised if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company recognized compensation expense for stock option awards and unvested restricted share awards that vest based on time or market parameters straight-line over the requisite service period for vesting of the award. Long Term Incentive Plan On July 18, 2016, the shareholders of the Company approved the 2016 Long Term Incentive Plan (“LTIP” or the "Plan") which replaced the 2010 Long Term Incentive Plan. The Company grants share based compensation to eligible participants under the 2016 LTIP. The total number of shares of common stock with respect to which awards may be granted under the plan is 2,000,000 including shares not previously authorized for issuance under any of the prior stock plans and any shares not issued or subject to outstanding awards under the prior stock plans. As of March 31, 2019 , 526,213 shares remain for future grants. The LTIP was designed as an omnibus plan and awards may consist of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, or stock bonuses. Under the Plan, the granting of awards to employees may take the form of options, restricted shares, and performance shares. The Compensation Committee of our Board of Directors determines the number of shares, the term, the frequency and date, the type, the exercise periods, any performance criteria pursuant to which awards may be granted, and the restriction and other terms and conditions of each grant in accordance with terms of the Plan. In connection with the acquisition of Magnetek, the Company agreed to continue the 2014 Stock Incentive Plan of Magnetek, Inc. (the "Magnetek Stock Plan"). In doing so, the Company has available under the Magnetek Stock Plan 164,461 of the Company's shares which can be granted to certain employees as stock based compensation. Stock Option Plans Existing prior to the adoption of the LTIP, the Company maintained two stock option plans, a Non-Qualified Stock Option Plan ("Non-Qualified Plan") and an Incentive Stock Option Plan ("Incentive Plan"). Effective with adoption of the LTIP no new grants can be made from the Non-Qualified Plan or the Incentive Stock Plan. Options outstanding under the Non-Qualified Plan or the Incentive Stock Plan generally become exercisable over a four -year period at a rate of 25% per year commencing one year from the date of grant and have an exercise price of not less than 100% of the fair market value of the common stock on the date of grant. Options granted under the Non-Qualified Plan or the Incentive Stock Plan are exercisable not earlier than one year and not later than ten years from the date such option was granted. A summary of option transactions during each of the three fiscal years in the period ended March 31, 2019 is as follows: Shares Weighted- average Exercise Price per share Weighted- average Remaining Contractual Life (in years) Aggregate Intrinsic Value Outstanding at April 1, 2016 718,801 20.13 6.64 $ 465 Granted 398,945 17.00 Exercised (27,848 ) 15.76 Cancelled (26,004 ) 19.06 Outstanding at March 31, 2017 1,063,894 19.10 6.98 $ 6,477 Granted 227,783 24.33 Exercised (363,091 ) 17.43 Cancelled (6,136 ) 19.83 Outstanding at March 31, 2018 922,450 21.04 7.56 $ 13,654 Granted 133,743 38.70 Exercised (187,907 ) 22.09 Cancelled (33,509 ) 23.94 Outstanding at March 31, 2019 834,777 23.52 7.04 $ 9,602 Exercisable at March 31, 2019 342,921 $ 20.71 5.74 $ 4,686 The Company calculated intrinsic value for those options that had an exercise price lower than the market price of our common shares as of March 31, 2019 . The aggregate intrinsic value of outstanding options as of March 31, 2019 is calculated as the difference between the exercise price of the underlying options and the market price of our common shares for the 706,752 options that were in-the-money at that date. The aggregate intrinsic value of exercisable options as of March 31, 2019 is calculated as the difference between the exercise price of the underlying options and the market price of our common shares for the 341,420 exercisable options that were in-the-money at that date. The Company's closing stock price was $34.35 as of March 31, 2019 . The total intrinsic value of stock options exercised was $3,577,000 , $5,851,000 , and $252,000 during fiscal 2019 , 2018 , and 2017 , respectively. The grant date fair value of options that vested was $7.36 , $7.42 , and $8.56 during fiscal 2019 , 2018 , and 2017 , respectively. As of March 31, 2019 , $2,727,000 of unrecognized compensation cost related to non-vested stock options is expected to be recognized over a weighted-average period of approximately 2.5 years. Exercise prices for options outstanding as of March 31, 2019 , ranged from $13.27 to $38.70 . The following table provides certain information with respect to stock options outstanding at March 31, 2019 : Stock Options Outstanding Weighted-average Exercise Price Weighted-average Remaining Contractual Life Range of Exercise Prices $10.01 to 20.00 317,938 $ 15.56 5.88 $20.01 to 30.00 388,814 25.02 7.33 $30.01 to $40.00 128,025 38.70 9.04 834,777 $ 23.52 7.04 The following table provides certain information with respect to stock options exercisable at March 31, 2019 : Range of Exercise Prices Stock Options Exercisable Weighted- average Exercise Price per share $10.01 to $20.00 172,842 $ 15.90 $20.01 to $30.00 168,578 25.47 $30.01 to $40.00 1,501 38.70 342,921 $ 20.71 The fair value of stock options granted was estimated on the date of grant using a Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of subjective assumptions including the expected stock price volatility. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. The weighted-average grant date fair value of the options was $13.56 , $7.66 , and $5.59 for options granted during fiscal 2019 , 2018 , and 2017 , respectively. The following table provides the weighted-average assumptions used to value stock options granted during fiscal 2019 , 2018 , and 2017 : Year Ended March 31, 2019 Year Ended March 31, 2018 Year Ended March 31, 2017 Assumptions: Risk-free interest rate 2.64 % 1.42 % 1.07 % Dividend yield 0.52 % 0.66 % 0.98 % Volatility factor 0.352 0.343 0.379 Expected life 5.5 years 5.5 years 5.5 years To determine expected volatility, the Company uses historical volatility based on daily closing prices of its Common Stock over periods that correlate with the expected terms of the options granted. The risk-free rate is based on the United States Treasury yield curve at the time of grant for the appropriate term of the options granted. Expected dividends are based on the Company's history and expectation of dividend payouts. The expected term of stock options is based on vesting schedules, expected exercise patterns and contractual terms. Restricted Stock Units The Company granted restricted stock units under the LTIP during fiscal 2019 , 2018 , and 2017 to employees as well as to the Company’s non-executive directors as part of their annual compensation. Restricted stock units for employees vest ratably based on service one-quarter after each of years one, two, three, and four. A summary of the restricted stock unit awards granted under the Company’s LTIP plan as of March 31, 2019 is as follows: Shares Weighted-average Grant Date Fair Value per share Unvested at April 1, 2016 371,502 $ 20.26 Granted 171,407 18.06 Vested (162,502 ) 19.93 Forfeited (10,151 ) 22.81 Unvested at March 31, 2017 370,256 $ 19.32 Granted 136,935 29.38 Vested (157,448 ) 20.39 Forfeited (12,954 ) 17.99 Unvested at March 31, 2018 336,789 $ 22.62 Granted 116,942 37.90 Vested (211,932 ) 22.66 Forfeited (11,602 ) 25.18 Unvested at March 31, 2019 230,197 $ 30.22 Total unrecognized compensation cost related to unvested restricted stock units as of March 31, 2019 is $4,564,000 and is expected to be recognized over a weighted average period of 2.6 years. The fair value of restricted stock units that vested during the year ended March 31, 2019 and 2018 was $4,802,000 and $3,210,000 , respectively. Performance Shares The Company granted performance shares under the LTIP during fiscal 2019 , 2018 , and 2017 . Performance based shares are recognized as compensation expense based upon their grant date fair value and to the extent it is probable that the performance conditions will be met. This expense is recognized ratably over the three year period that these shares are restricted. Fiscal 2017 performance shares granted vest pursuant to a performance condition based upon the Company’s Consolidated Net Sales. During fiscal 2019, the Company determined that the fiscal year 2017 performance shares would not vest due to the performance condition not being met. Fiscal 2018 performance shares granted vest pursuant to a performance condition based upon the Company’s Consolidated Net Sales. During fiscal 2019, the Company determined that the fiscal year 2018 performance shares were earned based on the performance condition being met. Fiscal 2019 performance shares granted vest pursuant to a performance condition based upon the Company’s Consolidated EBITDA margin for the twelve months ended March 31, 2020. At this time we believe it is probable that the March 31, 2020 performance condition will be met. A summary of the performance shares transactions during each of the three fiscal years in the period ended March 31, 2019 is as follows: Shares Weighted-average Grant Date Fair Value per share Unvested at April 1, 2016 101,653 $ 26.15 Granted 77,349 15.69 Vested (25,148 ) 26.79 Forfeited (35,001 ) 27.12 Unvested at March 31, 2017 118,853 $ 18.92 Granted 49,221 25.28 Forfeited (41,504 ) 24.94 Unvested at March 31, 2018 126,570 $ 19.42 Granted 34,695 36.43 Forfeited (7,879 ) 22.40 Unvested at March 31, 2019 153,386 $ 23.11 The Company had $2,051,000 in unrecognized compensation costs related to the unvested performance share awards as of March 31, 2019 as the performance criteria is not expected to be met. Directors Stock During fiscal 2019 , 2018 , and 2017 , a total of 10,031 , 16,667 , and 27,960 shares of stock, respectively, were granted under the LTIP to the Company’s non-executive directors as part of their annual compensation. The weighted average fair value grant price of those shares was $41.88 , $25.80 , and $15.74 for fiscal 2019 , 2018 , and 2017 , respectively. The expense related to the shares for fiscal 2019 , 2018 , and 2017 was $430,000 for each of the three years. Shareholder Rights Plan On March 29, 2018 the Company announced that its Board of Directors had amended the Company's Shareholder Rights Plan, which accelerated the expiration of the Company's preferred share purchase rights to March 31, 2018. Prior to its expiration, preferred share purchase right holders could exercise their rights if a person or group acquired 20% or more of the Company’s common shares or announced a tender offer for 20% or more of the common shares. Dividends On March 26, 2019 the Company's Board of Directors approved payment of a quarterly dividend of $0.06 per common share, representing an annual dividend rate of $0.24 per share. The dividend was paid on May 13, 2019 to shareholders of record on May 3, 2019 and totaled approximately $1,405,000 . Stock Repurchase Plan On March 26, 2019, the Board of Directors approved a new stock repurchase program authorizing the repurchase of up to $20 million of the Company's common stock. No repurchases were made during the year ended March 31, 2019.

Loss Contingencies

Loss Contingency [Abstract]
Loss Contingencies	Loss Contingencies From time to time, the Company is named a defendant in legal actions arising out of the normal course of business. The Company is not a party to any pending legal proceeding other than ordinary, routine litigation incidental to our business. The Company does not believe that any of our pending litigation will have a material impact on its business. Accrued general and product liability costs are actuarially estimated reserves based on amounts determined from loss reports, individual cases filed with the Company, and an amount for losses incurred but not reported. The aggregate amounts of reserves were $12,686,000 and $13,582,000 of which $9,185,000 and $10,082,000 are included in Other non current liabilities and $3,500,000 in Accrued liabilities for both years as of March 31, 2019 and 2018 , respectively. The liability for accrued general and product liability costs are funded by investments in marketable securities (see Notes 2 and 7). The following table provides a reconciliation of the beginning and ending balances for accrued general and product liability: Year Ended March 31, 2019 2018 2017 Accrued general and product liability, beginning of year $ 13,582 $ 13,335 $ 14,535 Add provision for claims 2,887 3,965 7,223 Deduct payments for claims (3,783 ) (3,718 ) (8,423 ) Accrued general and product liability, end of year $ 12,686 $ 13,582 $ 13,335 The per occurrence limits on the self-insurance for general and product liability coverage to Columbus McKinnon through its wholly-owned captive insurance company were $2,000,000 from inception through fiscal 2003 and $3,000,000 for fiscal 2004 and thereafter. In addition to the per occurrence limits, the Company’s coverage is also subject to an annual aggregate limit, applicable to losses only. These limits range from $2,000,000 to $6,000,000 for each policy year from inception through fiscal 2019 . Along with other manufacturing companies, the Company is subject to various federal, state, and local laws relating to the protection of the environment. To address the requirements of such laws, the Company has adopted a corporate environmental protection policy which provides that all of its owned or leased facilities shall, and all of its employees have the duty to, comply with all applicable environmental regulatory standards, and the Company utilizes an environmental auditing program for its facilities to ensure compliance with such regulatory standards. The Company has also established managerial responsibilities and internal communication channels for dealing with environmental compliance issues that may arise in the course of its business. Because of the complexity and changing nature of environmental regulatory standards, it is possible that situations will arise from time to time requiring the Company to incur expenditures in order to ensure environmental regulatory compliance. However, the Company is not aware of any environmental condition or any operation at any of its facilities, either individually or in the aggregate, which would cause expenditures having a material adverse effect on its results of operations, financial condition or cash flows and, accordingly, has not budgeted any material capital expenditures for environmental compliance for fiscal 2020. We have entered a voluntary environmental cleanup program in certain states where we operate and believe that our current reserves are sufficient to remediate these locations. For all of the currently known environmental matters, we have accrued as of March 31, 2019, a total of $1,075,000 which, in our opinion, is sufficient to deal with such matters. The Company is not aware of any environmental condition or any operation at any of its facilities, either individually or in the aggregate, which would cause expenditures to have a material adverse effect on its results of operations, financial condition or cash flows and, accordingly, has not budgeted any material capital expenditures for environmental compliance for fiscal 2019 . Like many industrial manufacturers, the Company is involved in asbestos-related litigation. In continually evaluating costs relating to its estimated asbestos-related liability, the Company reviews, among other things, the incidence of past and recent claims, the historical case dismissal rate, the mix of the claimed illnesses and occupations of the plaintiffs, its recent and historical resolution of the cases, the number of cases pending against it, the status and results of broad-based settlement discussions, and the number of years such activity might continue. Based on this review, the Company has estimated its share of liability to defend and resolve probable asbestos-related personal injury claims. This estimate is highly uncertain due to the limitations of the available data and the difficulty of forecasting with any certainty the numerous variables that can affect the range of the liability. The Company will continue to study the variables in light of additional information in order to identify trends that may become evident and to assess their impact on the range of liability that is probable and estimable. Based on actuarial information, the Company has estimated its asbestos-related aggregate liability including related legal costs to range between $4,100,000 and $8,000,000 using actuarial parameters of continued claims for a period of 37 years from March 31, 2019 . The Company's estimation of its asbestos-related aggregate liability that is probable and estimable, in accordance with U.S. generally accepted accounting principles approximates $5,697,000 , which has been reflected as a liability in the consolidated financial statements as of March 31, 2019 . The recorded liability does not consider the impact of any potential favorable federal legislation. This liability will fluctuate based on the uncertainty in the number of future claims that will be filed and the cost to resolve those claims, which may be influenced by a number of factors, including the outcome of the ongoing broad-based settlement negotiations, defensive strategies, and the cost to resolve claims outside the broad-based settlement program. Of this amount, management expects to incur asbestos liability payments of approximately $2,000,000 over the next 12 months. Because payment of the liability is likely to extend over many years, management believes that the potential additional costs for claims will not have a material effect on the financial condition of the Company or its liquidity, although the effect of any future liabilities recorded could be material to earnings in a future period. The Company believes that a share of its previously incurred asbestos-related expenses and future asbestos-related expenses are covered by pre-existing insurance policies. The Company has engaged in a legal action against the insurance carriers for those policies to recover these expenses and future costs incurred. When the Company resolves this legal action, it is expected that a gain will be recorded for previously expensed cost that is recovered. During fiscal 2019 and fiscal 2018, the Company received settlement payments $484,000 and $2,362,000 , respectively, net of legal fees, from its insurance carriers as partial reimbursement for asbestos-related expenses. These partial payments have been recorded as gains in cost of products sold. The Company is continuing its actions to recover further past costs and to cover future costs. The Company is also involved in other unresolved legal actions that arise in the normal course of business. The most prevalent of these unresolved actions involve disputes related to product design, manufacture and performance liability. The Company's estimation of its product-related aggregate liability that is probable and estimable, in accordance with U.S. generally accepted accounting principles approximates $6,100,000 , which has been reflected as a liability in the consolidated financial statements as of March 31, 2019 . In some cases, we cannot reasonably estimate a range of loss because there is insufficient information regarding the matter. Management believes that the potential additional costs for claims will not have a material effect on the financial condition of the Company or its liquidity, although the effect of any future liabilities recorded could be material to earnings in a future period. The following loss contingencies relate to the Company's Magnetek subsidiary: Product Liability Magnetek has been named, along with multiple other defendants, in asbestos-related lawsuits associated with business operations previously acquired but which are no longer owned. During Magnetek's ownership, none of the businesses produced or sold asbestos-containing products. For such claims, Magnetek is uninsured and either contractually indemnified against liability, or contractually obligated to defend and indemnify the purchaser of these former business operations. The Company aggressively seeks dismissal from these proceedings. Based on actuarial information, the asbestos related liability including legal costs is estimated to be approximately $889,000 which has been reflected as a liability in the consolidated financial statements at March 31, 2019 . Litigation-Other In October 2010, Magnetek received a request for indemnification from Power-One, Inc. ("Power-One") for an Italian tax matter arising out of the sale of Magnetek's power electronics business to Power-One in October 2006. With a reservation of rights, Magnetek affirmed its obligation to indemnify Power-One for certain pre-closing taxes. The sale included an Italian company, Magnetek, S.p.A., and its wholly owned subsidiary, Magnetek Electronics (Shenzhen) Co. Ltd. (the “Power-One China Subsidiary”). The tax authority in Arezzo, Italy, issued a notice of audit report in September 2010 wherein it asserted that the Power-One China Subsidiary had its administrative headquarters in Italy with fiscal residence in Italy and, therefore, is subject to taxation in Italy. In November 2010, the tax authority issued a notice of tax assessment for the period of July 2003 to June 2004, alleging that taxes of approximately $2,100,000 (Euro 1,900,000) were due in Italy on taxable income earned by the Power-One China Subsidiary during this period. In addition, the assessment alleges potential penalties together with interest in the amount of approximately $2,900,000 (Euro 2,600,000) for the alleged failure of the Power-One China Subsidiary to file its Italian tax return. The Power-One China Subsidiary filed its response with the provincial tax commission of Arezzo, Italy in January 2011. The tax authority in Arezzo, Italy issued a tax inspection report in January 2011 for the periods July 2002 to June 2003 and July 2004 to December 2006 claiming that the Power-One China Subsidiary failed to file Italian tax returns for the reported periods. A hearing before the Tax Court was held in July 2012 on the tax assessment for the period of July 2003 to June 2004. In September 2012, the Tax Court ruled in favor of the Power-One China Subsidiary dismissing the tax assessment for the period of July 2003 to June 2004. In February 2013, the tax authority filed an appeal of the Tax Court's September 2012 ruling. The Regional Tax Commission of Florence heard the appeal of the tax assessment dismissal for the period of July 2003 to June 2004 and thereafter issued its ruling finding in favor of the tax authority. Magnetek believes the court’s decision was based upon erroneous interpretations of the applicable law and appealed the ruling to the Italian Supreme Court in April 2015. In August 2012, the tax authority in Arezzo, Italy issued notices of tax assessment for the periods July 2002 to June 2003 and July 2004 to December 2006, alleging that taxes of approximately $7,500,000 (Euro 6,700,000) were due in Italy on taxable income earned by the Power-One China Subsidiary together with an allegation of potential penalties in the amount of approximately $3,100,000 (Euro 2,800,000) for the alleged failure of the Power-One China Subsidiary to file its Italian tax returns. On June 3, 2015, the Tax Court ruled in favor of the Power-One China Subsidiary dismissing the tax assessments for the periods of July 2002 to June 2003 and July 2004 to December 2006. On July 27, 2015, the tax authority filed an appeal of the Tax Court's ruling of June 3, 2015. In May 2016, the Regional Tax Court of Florence rejected the appeal of the tax authority and at the same time canceled the notices of assessment for the fiscal years of 2004/2005 and 2005/2006. The tax authority had up to six months to appeal the decision. In December 2016, Magnetek was served by the Italian Revenue Service with two appeals to the Italian Supreme Court regarding the two positive judgments on the tax assessments for the fiscal periods 2004/2005 and 2005/2006. In March 2017, the tax authority rejected the appeal of the assessment for 2005/2006 fiscal year. The tax authority had until October 2017 to appeal this decision. In October 2017, Magnetek was served by the Italian Revenue Service with an appeal to the Italian Supreme Court against the positive judgment on the tax assessment for fiscal year 2005/2006. In November 2017 Magnetek filed a memorandum with the Italian Revenue Service and the Italian Supreme Court in response to the appeal made by the tax authority. In February 2018 an appeal hearing was held at the Regional Tax Court of Florence regarding the Italian tax authority's claim for taxes due for fiscal 2002/2003. In October 2018 Magnetek was served by the Italian Revenue Service with an appeal to the Italian Supreme Court against the positive judgment on the tax assessment for fiscal year 2002/2003. In November 2018 Magnetek filed a memorandum with the Italian Supreme Court in response to the appeal made by the tax authority. The Company believes it will be successful and does not expect to incur a liability related to these assessments. Environmental Matters From time to time, Magnetek has taken action to bring certain facilities associated with previously owned businesses into compliance with applicable environmental laws and regulations. Upon the subsequent sale of certain businesses, Magnetek agreed to indemnify the buyers against environmental claims associated with the divested operations, subject to certain conditions and limitations. Remediation activities, including those related to indemnification obligations, did not involve material expenditures during fiscal year 2019 . Magnetek has also been identified by the United States Environmental Protection Agency and certain state agencies as a potentially responsible party for cleanup costs associated with alleged past waste disposal practices at several previously utilized, owned or leased facilities and offsite locations. Its remediation activities as a potentially responsible party were not material in fiscal year 2019 . Although the materiality of future expenditures for environmental activities may be affected by the level and type of contamination, the extent and nature of cleanup activities required by governmental authorities, the nature of Magnetek's alleged connection to the contaminated sites, the number and financial resources of other potentially responsible parties, the availability of indemnification rights against third parties, and the identification of additional contaminated sites, Magnetek's estimated share of liability, if any, for environmental remediation, including its indemnification obligations, is not expected to be material. In 1986, Magnetek acquired the stock of Universal Manufacturing Corporation (“Universal”) from a predecessor of Fruit of the Loom (“FOL”), and the predecessor agreed to indemnify Magnetek against certain environmental liabilities arising from pre-acquisition activities at a facility in Bridgeport, Connecticut. Environmental liabilities covered by the indemnification agreement included completion of additional cleanup activities, if any, at the Bridgeport facility and defense and indemnification against liability for potential response costs related to offsite disposal locations. Magnetek's leasehold interest in the Bridgeport facility was assigned to the buyer in connection with the sale of Magnetek's transformer business in June 2001. FOL, the successor to the indemnification obligation, filed a petition for Reorganization under Chapter 11 of the Bankruptcy Code in 1999 and Magnetek filed a proof of claim in the proceeding for obligations related to the environmental indemnification agreement. Magnetek believes that FOL had substantially completed the clean-up obligations required by the indemnification agreement prior to the bankruptcy filing. In November 2001, Magnetek and FOL entered into an agreement involving the allocation of certain potential tax benefits and Magnetek withdrew its claims in the bankruptcy proceeding. Magnetek further believes that FOL's obligation to the state of Connecticut was not discharged in the reorganization proceeding. In January 2007, the Connecticut Department of Environmental Protection (“DEP”) requested parties, including Magnetek, to submit reports summarizing the investigations and remediation performed to date at the site and the proposed additional investigations and remediation necessary to complete those actions at the site. DEP requested additional information relating to site investigations and remediation. Magnetek and the DEP agreed to the scope of the work plan in November 2010. The Company has recorded a liability of $456,000 , included in the amount specified above, related to the Bridgeport facility, representing the best estimate of future site investigation costs and remediation costs which are expected to be incurred in the future. The Company has recorded total liabilities of $595,000 for all environmental matters related to Magnetek in the consolidated financial statements as of March 31, 2019 on an undiscounted basis. In September of 2017, Magnetek received a request for defense and indemnification from Monsanto Company, Pharmacia, LLC, and Solutia, Inc. (collectively, “Monsanto”) with respect to: (1) lawsuits brought by plaintiffs claiming that Monsanto manufactured polychlorinated biphenyls ("PCBs"), exposure to which allegedly caused injury to plaintiffs; and (2) lawsuits brought by municipalities and municipal entities claiming that Monsanto should be responsible for a variety of damages due to the presence of PCBs in bodies of water in those municipalities and/or in water treated by those municipal entities. Monsanto claims to be entitled to defense and indemnification from Magnetek under a so-called “Special Undertaking” apparently executed by Universal in January of 1972, which purportedly required Universal to defend and indemnify Monsanto from liabilities “arising out of or in connection with the receipt, purchase, possession, handling, use, sale or disposition of” PCBs by Universal. Magnetek has declined Monsanto’s tender, and believes that it has meritorious legal and factual defenses to the demands made by Monsanto. Magnetek is vigorously defending against those demands and has commenced litigation to, among other things, declare the Special Undertaking void and unenforceable. Monsanto has, in turn, commenced an action to enforce the Special Undertaking. Magnetek intends to continue to vigorously prosecute its declaratory judgment action and to defend against Monsanto’s action against it. We cannot reasonably estimate a potential range of loss with respect to Monsanto’s tender because there is insufficient information regarding the underlying matters. Management believes, however, that the potential additional legal costs related to such matters will not have a material effect on the financial condition of the Company or its liquidity, although the effect of any future liabilities recorded could be material to earnings in a future period. As of March 31, 2019 the Company has recorded a reserve of $100,000 for legal costs incurred to date and expected to be incurred related to this matter.

Income Taxes

Income Tax Disclosure [Text Block]	17. Income Taxes On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (“Tax Reform Act” or “the Act”). The legislation significantly changed U.S. tax law by, among other things, lowering corporate income tax rates, assessing a one-time transition tax on a deemed repatriation of non-previously taxed earnings of foreign subsidiaries, and implementing a territorial tax system. While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions. The Act also provides for the foreign-derived intangible income (“FDII”) deduction for corporations that derive gross income from export activities The GILTI provisions require the Company to include in its U.S. income tax return any foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company recorded no additional income tax expense as a result of GILTI for the year ended March 31, 2019 . This was primarily the result of the impact of the loss on sale of a foreign subsidiary during the current year. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the years ended March 31, 2019 and 2018 . The BEAT provisions in the Tax Reform Act eliminate the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. The BEAT tax had no impact on the Company's consolidated financial statements for the years ended March 31, 2019 and 2018 . The FDII provisions of the Act provide an incentive to domestic corporations in the form of a lower tax rate on income derived from tangible and intangible products and services in foreign markets. This lower tax rate is accomplished via an additional tax deduction based on a percentage of qualifying sales. The FDII deduction provided the Company an additional tax benefit of $ 945,000 in the year ended March 31, 2019 . SAB 118 measurement period adjustments On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. We applied the guidance in SAB 118 when accounting for the enactment-date effects of the Act in 2017 and throughout 2018. At December 31, 2017, we had not completed our accounting for all of the enactment-date income tax effects of the Act under ASC 740, Income Taxes, for the following aspects: remeasurement of deferred tax assets and liabilities and one-time transition tax. As of December 31, 2018, we completed our accounting for all of the enactment-date income tax effects of the Act, the impacts of which are summarized below. One-time transition tax The one-time transition tax is based on our total post-1986 earnings and profits ("E&P"), the tax on which we previously substantially deferred from U.S. income taxes under U.S. law. We recorded a provisional amount for our one-time transition tax liability for each of our foreign subsidiaries, resulting in a transition tax liability of $ 1,500,000 at March 31, 2018. Upon further analysis of the Act, Notices and regulations issued and proposed by the U.S. Department of the Treasury and the Internal Revenue Service, we finalized our calculations of the transition tax liability during the quarter ended December 31, 2018. We decreased our March 31, 2018 provisional amount of $ 1,500,000 to zero, the effect of which is included as a component of income tax expense in fiscal 2019. Deferred tax assets and liabilities As of December 31, 2017 we remeasured certain deferred tax assets and liabilities based on the rates at which they were expected to reverse in the future (which was generally 21 %), by recording a provisional amount of $ 16,128,000 . Based upon further analysis completed during the measurement period, we reduced this estimate by $ 26,000 during the year ended March 31, 2018. No further adjustments were made to this provisional amount during the measurement period. Global intangible low-taxed income The Company has elected to account for Global Intangible Low Taxed Income ("GILTI") tax in the period in which it is incurred, and therefore has not recorded any deferred tax impacts of GILTI in its consolidated financial statements for the year ended March 31, 2019 or 2018 . As noted above, the current year GILTI tax had no effect on our annual effective tax rate. The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate to income from continuing operations before income tax expense. The sources and tax effects of the differences were as follows: Year Ended March 31, 2019 2018 2017 Statutory federal income tax rate (1) 21.00 % 31.55 % 35.00 % Expected tax at statutory rate $ 11,108 $ 15,676 $ 4,560 Effect of Tax Reform Act (2), (3) (1,500 ) 17,602 — State income taxes net of federal benefit 1,728 (37 ) 893 Foreign taxes at rates other than statutory federal rate (145 ) (2,667 ) (1,921 ) Net loss on sale of businesses (5) 4,041 — — Permanent items (1,694 ) (2,220 ) 2,521 Valuation allowance (4) 13,190 (104 ) (829 ) Foreign tax credits (4) (15,371 ) — — Research and development credits (1,411 ) (612 ) (643 ) Other 375 (18 ) (538 ) Actual tax provision expense $ 10,321 $ 27,620 $ 4,043 (1) For fiscal 2018, represents the blended rate of 35 percent for the first three quarters of the fiscal year and 21 percent for the fourth quarter. (2) For fiscal 2018, represents the discrete expense of the one-time transition tax ( $1,500,000 ) and the remeasurement of our net U.S. deferred tax assets at the new lower U.S. corporate income tax rate ($ 16,102,000 ). (3) For fiscal 2019, represents the discrete benefit of the reduction of the one-time transition tax of $ 1,500,000 recorded in fiscal 2018 to zero. (4) For fiscal 2019, primarily represents foreign tax credits generated by the one-time transition tax calculation and valuation allowance as the Company believes their utilization is uncertain. (5) For fiscal 2019, represents losses on sales of businesses that are not deductible for income tax purposes. The provision for income tax expense (benefit) consisted of the following: Year Ended March 31, 2019 2018 2017 Current income tax expense (benefit): United States Federal $ (1,663 ) $ 1,109 $ 41 State taxes 394 402 217 Foreign 12,548 6,141 3,296 Deferred income tax expense (benefit): United States 5,873 21,177 5,797 Foreign (6,831 ) (1,209 ) (5,308 ) $ 10,321 $ 27,620 $ 4,043 The Company applies the liability method of accounting for income taxes as required by ASC Topic 740, “Income Taxes.” The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows: March 31, 2019 2018 Deferred tax assets: Federal net operating loss carryforwards $ 21,990 $ 26,450 State and foreign net operating loss carryforwards 8,069 10,376 Employee benefit plans 27,955 28,390 Insurance reserves 3,204 3,578 Accrued vacation and incentive costs 4,766 4,625 Federal tax credit carryforwards 17,685 2,476 Equity compensation 2,285 2,285 Other 4,449 3,666 Valuation allowance (16,881 ) (4,671 ) Deferred tax assets after valuation allowance 73,522 77,175 Deferred tax liabilities: Property, plant, and equipment (2,429 ) (2,785 ) Intangible assets (63,468 ) (72,210 ) Total deferred tax liabilities (65,897 ) (74,995 ) Net deferred tax assets (liabilities) $ 7,625 $ 2,180 The net deferred tax asset increased in fiscal 2019 primarily as a result of the amortization of certain intangible assets, offset by the utilization of federal and state net operating losses and the net increase to foreign tax credits after valuation allowance. The gross amount of the Company’s deferred tax assets were $90,403,000 and $81,846,000 at March 31, 2019 and 2018 , respectively. The valuation allowance includes $ $2,372,000 , $3,837,000 , and $4,370,000 related to foreign net operating losses at March 31, 2019 , 2018 , and 2017 , respectively. The increase in the domestic valuation allowance is primarily due to uncertainty related to the utilization of certain foreign tax credits generated by the one-time transition tax. The decrease in the foreign valuation allowance is primarily due to the use of net operating losses which had valuation allowances recorded against them for certain foreign subsidiaries of the Company. The Company’s foreign subsidiaries have net operating loss carryforwards that expire in periods ranging from five years to indefinite. The federal net operating losses arose from the acquisition of Magnetek and have expiration dates ranging from 2020 through 2035. The state net operating losses have expiration dates ranging from 2019 through 2038. The federal tax credits have expiration dates ranging from 2032 to indefinite. Deferred income taxes are classified within the consolidated balance sheets based on the following breakdown: March 31, 2019 2018 Net non-current deferred tax assets $ 27,707 $ 32,442 Net non-current deferred tax liabilities (20,082 ) (30,262 ) Net deferred tax assets (liabilities) $ 7,625 $ 2,180 Net non-current deferred tax liabilities are included in other non-current liabilities. Income from continuing operations before income tax expense includes foreign subsidiary income of $14,362,000 , $25,144,000 , and $3,071,000 for the years ended March 31, 2019 , 2018 , and 2017 , respectively. As of March 31, 2019 , the Company had approximately $114,000,000 of undistributed earnings of foreign subsidiaries. These earnings are considered to be permanently invested in operations outside the U.S. with the exception of the current earnings from two foreign subsidiaries. Any repatriation of these amounts would not be expected to result in a material increase to income tax expense due to the one-time transition tax and the new U.S. territorial tax system. Determination of the amount of unrecognized deferred U.S. income tax liability with respect to such earnings is not practicable. During fiscal 2018, the Company adopted ASU No. 2016-09. There were shares of common stock issued through restricted stock units, the exercise of non-qualified stock options, or through the disqualifying disposition of incentive stock options in the years ended March 31, 2019 and 2018 . The tax effect to the Company from these share transactions during fiscal 2019 and 2018 was a reduction to income tax expense of ($ 1,129,000 ) and ( $1,230,000 ), respectively. Changes in the Company’s uncertain income tax positions, excluding the related accrual for interest and penalties, are as follows: 2019 2018 2017 Beginning balance $ 592 $ 975 $ 1,092 Additions for tax positions of the current year 550 444 — Reductions for prior year tax positions (141 ) — — Settlements — — — Foreign currency translation (65 ) 20 (9 ) Lapses in statutes of limitation — (847 ) (108 ) Ending balance $ 936 $ 592 $ 975 The Company had $38,000 and $33,000 accrued for the payment of interest and penalties at March 31, 2019 and 2018 , respectively. The Company recognizes interest expense or penalties related to uncertain tax positions as a part of income tax expense in its consolidated statements of operations. All of the unrecognized tax benefits as of March 31, 2019 would impact the effective tax rate if recognized. The Company and its subsidiaries file income tax returns in the U.S., various state, local, and foreign jurisdictions. The Internal Revenue Service has completed an examination of the Company’s U.S. income tax returns for fiscal 2015 resulting in no adjustments. The Company has no current U.S. income tax examinations or audits. The Company’s major tax jurisdictions are the United States and Germany. With few exceptions, the Company is no longer subject to tax examinations by tax authorities in the United States for tax years prior to March 31, 2016 and in Germany for tax years prior to March 31, 2011. The Company has a current tax examination in Germany for fiscal years 2012 to 2014. The Company anticipates that total unrecognized tax benefits will change due to the expiration of statutes and the enactment of legislation in certain foreign jurisdictions prior to March 31, 2020.

Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss is as follows: March 31, 2019 2018 Foreign currency translation adjustment – net of tax $ (25,355 ) $ (8,647 ) Pension liability – net of tax (55,601 ) (49,889 ) Postretirement obligations – net of tax 1,847 1,372 Split-dollar life insurance arrangements – net of tax (1,391 ) (1,462 ) Derivatives qualifying as hedges – net of tax (2,552 ) (1,515 ) Net unrealized investment gain – net of tax — 883 Accumulated other comprehensive loss $ (83,052 ) $ (59,258 ) The deferred taxes related to the adjustments associated with the items included in accumulated other comprehensive loss, net of deferred tax asset valuation allowances, were $2,566,000 , $(6,848,000) , and $(5,579,000) for fiscal 2019 , 2018 , and 2017 respectively. Refer to Note 17 for discussion of the deferred tax asset valuation allowance. In the period subsequent to our initial recording of the valuation allowance in fiscal 2011, increases and decreases to both the deferred tax assets associated with items in accumulated other comprehensive loss, and the valuation allowance, have been recorded as offsets to comprehensive income. As a result of the Act as described in Note 17, the Company recorded as an offsetting entry a $(9,477,000) stranded tax effect in the minimum pension liability component and a $(194,000) stranded tax effect in the split dollar life insurance arrangement component of other comprehensive income in fiscal 2018. The stranded tax effect related to the other post retirement obligations component was not material. As a result of the recording of a deferred tax asset valuation allowance in fiscal 2011, the Company recorded as an offsetting entry a $10,006,000 stranded tax effect in the minimum pension liability component, $935,000 stranded tax effect in the other post retirement obligations component and a $747,000 stranded tax effect in the split dollar life insurance arrangement component of other comprehensive income. With the reversal of that valuation allowance in fiscal 2013, the Company recorded the reversal of the valuation allowance as a reduction of income taxes in the consolidated statement of operations. As a result of the recording of a deferred tax asset valuation allowance in fiscal 2005, the Company recorded as an offsetting entry a $534,000 stranded tax effect in the minimum pension liability component of other comprehensive income. With the reversal of that valuation allowance in fiscal 2006, the Company recorded the reversal of the valuation allowance as a reduction of income taxes in the consolidated statement of operations. The stranded tax effects described above are in accordance with ASC Topic 740, “Income Taxes” even though the impact of the act and the deferred tax asset valuation allowance described above were initially established as an adjustment to comprehensive income. This amount will remain indefinitely as a component of accumulated other comprehensive loss. As described in Note 22, the Company is evaluating the impact ASU 2018-02 will have accumulated other comprehensive income. Refer to Note 22 for additional information.

New Accounting Standards [Abstract]
Effects of New Accounting Pronouncements	Effects of New Accounting Pronouncements In March 2019, the FASB issued ASU No. 2019-01, "Codification Improvements: Leases (Topic 842)." The ASU clarifies transition disclosure requirements, specifically that entities are not subject to the transition disclosure requirements in ASC 250 related to the effect on income of an accounting change on certain interim period information. The ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted no earlier than when the entity adopts ASC 842. In December 2018, the FASB issued ASU No. 2018-20, "Narrow-Scope Improvements for Lessors (Topic 842)." The ASU gives lessors elections to account for the following under the new lease standard: sales taxes and other similar taxes collected from lessees, lessor costs paid directly by a lessee, and recognition of variable payments for contracts with lease and nonlease components. The ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted no earlier than when the entity adopts ASC 842. In July 2018, the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements." Under the ASU, entities may elect not to recast the comparative periods presented when transitioning to ASC 842 and lessors may elect not to separate lease and nonlease components when certain conditions are met. The ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted no earlier than when the entity adopts ASC 842. In July 2018, the FASB issued ASU No. 2018-10, "Codification Improvements to Topic 842." Under the ASU, various aspects within ASC 842 were improved, such as the rate implicit in the lease, lessee's reassessment of lease classification, lease term and purchase option, as well as many others aspects of the guidance. The ASU is effective when the entity adopts ASC 842. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." This standard will require all leases with durations greater than twelve months to be recognized on the balance sheet as right-of-use ("ROU") assets and leases liabilities. This ASU is effective for interim and annual reporting periods beginning after December 15, 2018, although early adoption is permitted. The Company will adopt ASC 842 in fiscal 2020 using the modified retrospective transition approach whereas prior periods will not be restated, therefore, presented in accordance with the previous lease standard (ASC 840). The Company intends to utilize the transition practical expedients that are permitted with the new standard when elected as a package, which allows the Company to not reassess the lease classification of existing leases. The Company will also elect the practical expedient to not separate lease and nonlease components from the ROU asset and leases liability as well as the practical expedient to not record leases with an initial term of 12 months or less (short-term leases) on the balance sheet. We are currently updating existing lease policies and developing new controls and business processes to comply with the new standard. The Company expects the ROU assets and lease liabilities to be less than 5% of total assets. During the first quarter of fiscal 2020 the Company will finalize its accounting assessment and quantification of the impact on the Company’s financial statements and corresponding disclosures. In November 2018, the FASB issued ASU No. 2018-19, "Codification Improvements to Topic 326: Financial Instruments - Credit Losses." The ASU changes the effective date of ASU 2016-13, Financial Instruments - Credit Losses, to fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact the standard will have on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. We are currently evaluating the impact the standard will have on our consolidated financial statements. In August 2018, the U.S. Securities and Exchange Commission ("SEC") issued its rule Disclosure Update and Simplification ("DUSTR") to eliminate, modify, or integrate into other SEC requirements certain disclosure rules. The DUSTR is part of the SEC’s overall project to improve disclosure effectiveness and is intended to simplify compliance without significantly altering the total mix of information provided to investors. In a limited number of situations, the DUSTR expanded the disclosure requirements. For example, an analysis of changes in stockholders’ equity will now be required for the current and comparative quarter and year-to-date interim periods. The DUSTR rules became effective on November 5, 2018 and must be applied to any filings after that date. The Company adopted this rule during the quarter ended December 31, 2018. In August 2018, the FASB issued ASU No. 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (Topic 350)." The ASU amends ASC 350 to include in its scope implementation costs of a Cloud Computing Arrangement ("CCA") that is a service contract and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA that is considered a service contract. The ASU is effective for fiscal years beginning after December 15, 2019 with early adoption permitted. The Company adopted the standard on a prospective basis effective July 1, 2018. The standard did not have a material impact on the financial statements for the twelve months ended as of March 31, 2019. In August 2018, the FASB issued ASU No. 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plan (Topic 715)." The ASU amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans such as a narrative description describing the reasons for significant gains and losses affecting the benefit obligation for the period and the removal of disclosing amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost over the next year. The ASU is effective for fiscal years beginning after December 15, 2020 with early adoption permitted. We anticipate this standard will change the disclosures in the Net Periodic Benefit Cost footnote in the Company's Form 10-K upon adoption. In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820)." The ASU changes the fair value measurement disclosure requirements including new, eliminated, and modified disclosure requirements of ASC 820. For instance, the ASU requires the addition of disclosures for Level 3 fair value measurements with unrealized gains and losses included in other comprehensive income and disclosure of the range of the weighted average used to develop significant unobservable inputs for Level 3 measurements. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years, with early adoption permitted for any eliminated or modified disclosures. We anticipate this standard will modify the disclosures in the Derivative Instruments footnote upon adoption. In July 2018, the FASB issued ASU No. 2018-09, "Codification Improvements." The ASU amendments represent changes to clarify, correct errors in, or make minor improvements to the Accounting Standards Codification ("Codification"). The amendments make the Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. The transition and effective date guidance is based on the facts and circumstances of each amendment, however, many of the amendments in the ASU have transition guidance with effective dates for fiscal years beginning after December 15, 2018 for public business entities. The standard did not have a material impact on the financial statements for the twelve months ended as of March 31, 2019. In June 2018, the FASB issued ASU No. 2018-07, "Improvements to Nonemployee Share-Based Payment Accounting (Topic 550 and 718)." The standard simplifies the accounting for share-based payments granted to nonemployees for goods and services. Under the ASU, most of the guidance on such payments to nonemployees (accounted for under ASC 550) would be aligned with the requirements for share-based payments granted to employees (accounted for under ASC 718). The ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted no earlier than when the entity adopts ASC 606. We do not anticipate that this standard will have a material effect on the consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASU amends ASC 220, Income Statement — Reporting Comprehensive Income, to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. In addition, under the ASU, an entity will be required to provide certain disclosures regarding stranded tax effects. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact the standard will have on our consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, "Targeted Improvements to Accounting for Hedging Activities (Topic 815)." The standard better aligns an entity’s financial reporting for hedging relationships with risk management activities and reduces the complexity for the application of hedge accounting. Changes include the ability to elect to perform subsequent effectiveness assessments qualitatively and the elimination of the concept of recognizing periodic hedge ineffectiveness for cash flow hedges. The ASU is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact the standard will have on our consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, "Compensation - Stock Compensation (Topic 718)." The standard provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The ASU is effective for fiscal years beginning after December 15, 2017 and interim periods within the fiscal year, with early adoption permitted. The Company adopted this standard effective April 1, 2018 and the standard did not have a significant impact on the Company's consolidated financial statements. On April 1, 2018, the Company adopted ASU No. 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (Topic 715)." The standard requires the current-service-cost component be disaggregated from the other components of net benefit cost. The current service cost is now presented with current compensation costs for related employees and the other components of net benefit cost is presented in Other (income) expense, net. In accordance with the ASU, the Company adopted the standard on a retrospective basis to all periods presented. As a result, the Company reclassified other components of net periodic benefit cost from Cost of products sold and General and administrative expenses to Other (income) expense, net in the amount of $1,768,000 and $2,248,000 on the Consolidated Statements of Operations for the twelve months ended March 31, 2018 and 2017, respectively. As a basis for the retrospective application of the ASU, the practical expedient was applied which permits the use of amounts disclosed for the various components of net periodic benefit cost in Note 13. In February 2017, the FASB issued ASU No. 2017-05, "Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (Topic 606)." The standard clarifies the scope of nonfinancial asset derecognition to include in-substance nonfinancial assets thereby requiring the nonfinancial asset to be derecognized in a partial sale transactions when the company no longer has a controlling financial interest in a subsidiary and control of the asset is transferred in accordance with ASC 606. The ASU amends industry specific guidance to align with the new revenue standard (ASC 606). The effective date is aligned with the new revenue standard, which is effective for fiscal years beginning after December 15, 2017. As described in Note 4, the Company adopted this standard effective April 1, 2018 and the standard did not have a significant impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, "Clarifying the Definition of a Business (Topic 805)." The amendment narrows the definition of a business as the guidance requires that when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or group of similar identifiable assets, the asset is not a business. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company adopted this standard effective April 1, 2018 and the standard did not have a significant impact on the Company's consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, "Restricted Cash (Topic 230)." The standard clarifies the classification and presentation of restricted cash in the statement of cash flows. The standard requires that restricted cash and restricted cash equivalents be included in the cash and cash equivalent balance in the statement of cash flows. Further, a reconciliation between the balance sheet and statement of cash flows is required when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Therefore, transfers between these balances should no longer be presented as a cash flow activity. The Company adopted this standard effective April 1, 2018. The following table provides a reconciliation of Cash and cash equivalents and Restricted Cash reported within the Consolidated Balance Sheets that agree to the total of the amount presented in the Consolidated Statements of Cash Flows (in thousands): March 31, 2019 March 31, 2018 March 31, 2017 Cash and cash equivalents at end of period, shown in the Consolidated Balance Sheets $ 71,093 $ 63,021 $ 77,591 Restricted cash within Prepaid expenses and other — 294 588 Restricted cash within Other assets 250 250 250 Total Cash, cash equivalents, and restricted cash at end of period, shown in the Consolidated Statements of Cash Flows $ 71,343 $ 63,565 $ 78,429 In October 2016, the FASB issued ASU No. 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory (Topic 740)." The standard requires immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted this standard effective April 1, 2018 and the standard did not have a significant impact on the Company's consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments (Topic 230)." The standard clarifies the classification of certain cash receipts and cash payments in the statement of cash flows. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted this standard effective April 1, 2018 and the standard did not have a significant impact on the Company's Consolidated Statements of Cash Flows. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The update addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments, including the Company's marketable securities. Under the new guidance, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. There will no longer be an available-for-sale classification for equity securities with readily determinable fair values. The Company adopted this standard effective April 1, 2018 and was applied on a modified retrospective basis through a cumulative effect adjustment of $888,000 to the beginning balance of retained earnings. Refer to Note 7 for additional information.

Accounting Principles and Pra_2

Accounting Principles and Practices (Policies)	12 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Advertising	Advertising Costs associated with advertising are expensed as incurred and are included in Selling expense in the Consolidated Statements of Operations.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers as cash equivalents all highly liquid investments with an original maturity of three months or less.
Concentration of Labor	Concentrations of Labor Approximately 10% of the Company’s employees are represented by three separate U.S. collective bargaining agreements which expire May 2020 , April 2021, and September 2021 .
Consolidation	Consolidation These consolidated financial statements include the accounts of the Company and its global subsidiaries; all significant intercompany accounts and transactions have been eliminated.
Schedule of Equity Method Investments [Line Items]	Equity Method Investment The Company has an investment in Eastern Morris Cranes Company Limited ("EMC") whose principal activity is to manufacture various electrical overhead traveling cranes. This investment represents a minority ownership interest that is accounted for under the equity method of accounting since the Company has significant influence over the investee. As a result, the Company records its portion of the gains and losses incurred by this entity in Investment (income) loss in the Consolidated Statements of Operations.
Foreign Currency Translations	Foreign Currency Translations The Company translates foreign currency financial statements as described in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 830, “Foreign Currency Matters.” Under this method, all items of income and expense are translated to U.S. dollars at average exchange rates during the year. All assets and liabilities are translated to U.S. dollars at the year-end exchange rate. Gains or losses on translations are recorded in accumulated other comprehensive loss in the shareholders’ equity section of the balance sheet. The functional currency is the foreign currency in which the foreign subsidiaries conduct their business. Gains and losses from foreign currency transactions are reported in foreign currency exchange loss (gain).
Goodwill	Goodwill Goodwill is not amortized but is tested for impairment at least annually, or more frequently if indicators of impairment exist, in accordance with the provisions of ASC Topic 350-20-35-1. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. The fair value of a reporting unit is determined using a discounted cash flow methodology. The Company’s reporting units are determined based upon whether discrete financial information is available and reviewed regularly, whether those units constitute a business, and the extent of economic similarities and interdependencies between those reporting units for purposes of aggregation. The Company’s reporting units identified under ASC Topic 350-20-35-33 are at the component level, or one level below the reporting segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting – Disclosure.” As of March 31, 2019, the Company’s one segment is subdivided into two reporting units. Further, the Company adopted ASU No. 2017-04, "Simplifying the Test for Goodwill Impairment (Topic 350)," in fiscal 2018, therefore, is no longer required to compare the implied fair value of goodwill with its carrying value amount as part of step two of the goodwill test. An impairment charge is the amount by which the carrying value is greater than the reporting unit's fair value (step one). When the Company evaluates the potential for goodwill impairment, it assesses a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for its products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value or if economic or other business factors indicate that the fair value of our reporting units may have declined since our last quantitative test, the Company performs a quantitative test. To perform the quantitative impairment test, the Company uses the discounted cash flow method to estimate the fair value of the reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating profit margins and cash flows, the terminal growth rate, and the discount rate. The Company projects revenue growth rates, operating margins and cash flows based on each reporting unit’s current business, expected developments and operational strategies over a five-year period. In estimating the terminal growth rate, the Company considers its historical and projected results, as well as the economic environment in which its reporting units operate. The discount rates utilized for each reporting unit reflect the Company’s assumptions of marketplace participants’ cost of capital and risk assumptions, both specific to the reporting unit and overall in the economy. The Company performed its qualitative assessment as of February 28, 2019 and determined that the quantitative goodwill impairment test was not required for the Rest of Products reporting unit. Based on various conditions in the current fiscal year, such as financial performance, macroeconomic conditions, and other company specific events, the Rest of Products reporting unit's fair value was likely not less than its applicable carrying value. The qualitative assessment for the Duff-Norton reporting unit indicated that a quantitative test should be performed. Based on results of the quantitative impairment test for the Duff-Norton reporting unit, the Company determined the fair value was not less than its carrying value. See Note 9 for further discussion of goodwill and intangible assets.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company assesses impairment of its long-lived assets in accordance with the provisions of ASC Topic 360 “Property, Plant, and Equipment.” This statement requires long-lived assets, such as property and equipment and purchased intangibles subject to amortization, to be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to estimated undiscounted future cash flows expected to be generated by the asset group over its remaining useful life. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized equal to the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. The fair values are determined in accordance with ASC 820. In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Asset grouping requires a significant amount of judgment. Accordingly, facts and circumstances will influence how asset groups are determined for impairment testing. In assessing long-lived assets for impairment, management considered the Company’s product line portfolio, customers and related commercial agreements, labor agreements and other factors in grouping assets and liabilities at the lowest level for which identifiable cash flows are independent. The Company considers projected future undiscounted cash flows, trends and other factors in its assessment of whether impairment conditions exist. While the Company believes that its estimates of future cash flows are reasonable, different assumptions regarding such factors as future production volumes, customer pricing, economics, and productivity and cost initiatives, could significantly affect its estimates. In determining fair value of long-lived assets, management uses management estimates, discounted cash flow calculations, and appraisals where necessary. Other than the impairment on Held for Sale Businesses, discussed in Note 3, no impairment was recorded related to long-lived assets in the current year.
Intangible Assets	Intangible Assets At acquisition, the Company estimates and records the fair value of purchased intangible assets which primarily consist of trade names, customer relationships, and technology. The fair values are estimated based on management’s assessment as well as independent third party appraisals. Such valuations may include a discounted cash flow of anticipated revenues resulting from the acquired intangible asset. Amortization of intangible assets with finite lives is recognized over their estimated useful lives using an amortization method that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise realized. The straight line method is used for customer relationships. As a result of the negligible attrition rate in our customer base, the difference between the straight line method and attrition method is not considered significant. The estimated useful lives for our intangible assets range from 1 to 25 years. Similar to goodwill, indefinite-lived intangible assets (including trademarks on our acquisitions) are tested for impairment on an annual basis. When the Company evaluates the potential for impairment of intangible assets, it assesses a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for its products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value or if economic or other business factors indicate that the fair value of our indefinite-lived intangible assets may have declined since our last quantitative test, the Company performs a new quantitative test. The methodology used to value trademarks is the relief from royalty method. The recorded book value of these trademarks in excess of the calculated fair value triggers an impairment. The key estimate used in this calculation consists of an overall royalty rate applied to the sales covered by the trademark. After performing a qualitative assessment as of February 28, 2019 , it was determined that the trademarks were not impaired.
Inventories	Inventories Inventories are valued at the lower of cost and net realizable value. Cost of approximately 36% and 30% of inventories at March 31, 2019 and March 31, 2018 , respectively, have been determined using the LIFO (last-in, first-out) method. Costs of other inventories have been determined using the FIFO (first-in, first-out) or average cost method. FIFO cost approximates replacement cost. Costs in inventory include components for direct labor and overhead costs.
Marketable Securities	Marketable Securities The Company’s marketable securities, which consist of equity and fixed income securities, are recorded at fair value. As described in Note 7, in the first quarter of fiscal 2019 the Company adopted ASU 2016-01 whereas all equity investments (including certain fixed income securities) in unconsolidated entities are measured at fair value through earnings. Therefore, gains and losses on marketable securities are no longer recorded in Shareholders' equity on the Consolidated Balance Sheets, rather, are realized within Investment (income) loss on the Consolidated Statements of Operations. Estimated fair value is based on published trading values at the balance sheet dates. The cost of securities sold is based on the specific identification method. Interest and dividend income are also included in Investment (income) loss on the Consolidated Statements of Operations. The marketable securities are carried as long-term assets since they are held for the settlement of the Company’s general and products liability insurance claims filed through CM Insurance Company, Inc., a wholly owned captive insurance subsidiary. The marketable securities are not available for general working capital purposes.
Property, Plant and Equipment	Property, Plant, and Equipment Property, plant, and equipment are stated at cost and depreciated principally using the straight-line method over their respective estimated useful lives (buildings and building equipment— 15 to 40 years; machinery and equipment— 3 to 18 years). When depreciable assets are retired, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operating results.
Research and Development	Research and Development With the acquisitions of Magnetek in September 2015 and STAHL CraneSystems (“STAHL”) in January 2017, the Company expects research and development ("R&D") costs to factor more prominently into its cost structure. Therefore, R&D costs are presented on the Consolidated Statement of Operations in order to provide transparency into these costs. Consistent with prior periods, the Company continues to account for R&D expenses in accordance with the provisions of ASC 730 and are expensed as incurred.
Revenue Recognition, Accounts Receivable and Concentration of Credit Risk	Revenue Recognition, Accounts Receivable, and Concentration of Credit Risk As described in Note 4, the Company adopted ASC 606, "Revenue from Contracts with Customers," in fiscal 2019. Revenue from contracts with customers for standard products is recognized when legal title and significant risk and rewards has transferred to the customer, which is generally at the time of shipment. This is the point in time when control is deemed to transfer to the customer. The Company also sells custom engineered products and services which are contracts that are typically completed within one quarter but can extend beyond one year in duration. The Company generally recognizes revenue for customer engineered products upon satisfaction of its performance obligation under the contract which typically coincides with project completion which is when the products and services are controlled by the customer. Control is typically achieved at the later of when legal title and significant risk and rewards have transferred to the customer or the customer has accepted the asset. For both standard products and custom engineered products, the transaction price is based upon the price stated in either the purchase order or contract. Refer to Note 4 for further details. Additionally, the Company performs ongoing credit evaluations of its customers’ financial condition, but generally does not require collateral to support customer receivables. The credit risk is controlled through credit approvals, limits, and monitoring procedures. Accounts receivable are reported at net realizable value and do not accrue interest. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends, and other factors. Accounts receivable are charged against the allowance for doubtful accounts once all collection efforts have been exhausted. The Company does not routinely permit customers to return product. However, sales returns are permitted in specific situations and typically include a restocking charge or the purchase of additional product.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs are a component of cost of products sold.
Share-based Compensation	Stock-Based Compensation The Company records stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation.” This standard requires all equity-based payments to employees, including grants of employee stock options, to be recognized in the Consolidated Statements of Operations based on the grant date fair value of the award. Stock compensation expense is included in Cost of products sold, Selling, and General and administrative expense depending on the nature of the service of the employee receiving the award. The Company uses a straight-line method of attributing the value of stock compensation expense, subject to minimum levels of expense, based on vesting. See Note 15 for further discussion of stock-based compensation.
Leases	Leases All leases are reviewed for capital or operating classification at their inception. Rent expense for leases that contain scheduled rent increases is recognized on a straight-line basis over the lease term.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Warranties	Warranties The Company offers warranties for certain products it sells. The specific terms and conditions of those warranties vary depending upon the product sold and the country in which the Company sold the product. As noted in the Revenue Recognition note (Note 4), the Company offers standard warranties which are typically 12 months in duration for standard products and 24 to 36 months for custom engineered products. These are assurance-type warranties that do not qualify as separate performance obligations under ASC 606. The Company estimates the costs that may be incurred under its standard warranties, based largely upon actual warranty repair costs history, and records a liability in the amount of such costs in the month that revenue is recognized. The resulting accrual balance is reviewed during the year. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rate of warranty claims, and cost per claim. Changes in the Company’s product warranty accrual are as follows:

[1]	21. Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss is as follows: March 31, 2019 2018Foreign currency translation adjustment – net of tax $(25,355) $(8,647)Pension liability – net of tax (55,601) (49,889)Postretirement obligations – net of tax 1,847 1,372Split-dollar life insurance arrangements – net of tax (1,391) (1,462)Derivatives qualifying as hedges – net of tax (2,552) (1,515)Net unrealized investment gain – net of tax — 883Accumulated other comprehensive loss $(83,052) $(59,258) The deferred taxes related to the adjustments associated with the items included in accumulated other comprehensive loss, net of deferred tax asset valuation allowances, were $2,566,000, $(6,848,000), and $(5,579,000) for fiscal 2019, 2018, and 2017 respectively. Refer to Note 17 for discussion of the deferred tax asset valuation allowance. In the period subsequent to our initial recording of the valuation allowance in fiscal 2011, increases and decreases to both the deferred tax assets associated with items in accumulated other comprehensive loss, and the valuation allowance, have been recorded as offsets to comprehensive income.As a result of the Act as described in Note 17, the Company recorded as an offsetting entry a $(9,477,000) stranded tax effect in the minimum pension liability component and a $(194,000) stranded tax effect in the split dollar life insurance arrangement component of other comprehensive income in fiscal 2018. The stranded tax effect related to the other post retirement obligations component was not material.As a result of the recording of a deferred tax asset valuation allowance in fiscal 2011, the Company recorded as an offsetting entry a $10,006,000 stranded tax effect in the minimum pension liability component, $935,000 stranded tax effect in the other post retirement obligations component and a $747,000 stranded tax effect in the split dollar life insurance arrangement component of other comprehensive income. With the reversal of that valuation allowance in fiscal 2013, the Company recorded the reversal of the valuation allowance as a reduction of income taxes in the consolidated statement of operations. As a result of the recording of a deferred tax asset valuation allowance in fiscal 2005, the Company recorded as an offsetting entry a $534,000 stranded tax effect in the minimum pension liability component of other comprehensive income. With the reversal of that valuation allowance in fiscal 2006, the Company recorded the reversal of the valuation allowance as a reduction of income taxes in the consolidated statement of operations. The stranded tax effects described above are in accordance with ASC Topic 740, “Income Taxes” even though the impact of the act and the deferred tax asset valuation allowance described above were initially established as an adjustment to comprehensive income. This amount will remain indefinitely as a component of accumulated other comprehensive loss. As described in Note 22, the Company is evaluating the impact ASU 2018-02 will have accumulated other comprehensive income. Refer to Note 22 for additional information.The activity by year related to investments, including reclassification adjustments for activity included in earnings are as follows (all items shown net of tax): Year Ended March 31, 2019 2018 2017Net unrealized investment gain (loss) at beginning of year $888 $699 $631Unrealized holdings gain (loss) arising during the period — 189 173Reclassification adjustments for gain included in earnings — — (105)Adoption of ASU 2016-01 (888) — —Net change in unrealized gain (loss) on investments (888) 189 68Net unrealized investment gain at end of year $— $888 $699Changes in accumulated other comprehensive income by component for the year ended March 31, 2019 are as follows (in thousands): March 31, 2019 Unrealized Investment Gain Retirement Obligations Foreign Currency Change in Derivatives Qualifying as Hedges TotalBeginning balance net of tax $888 $(49,984) $(8,647) $(1,515) (59,258)Other comprehensive income (loss) before reclassification — (6,720) (16,708) 16,943 (6,485)Amounts reclassified from other comprehensive loss to net income — 1,559 (17,980) (16,421)Adoption of ASU 2016-01 (888) — — — (888)Net current period other comprehensive (loss) income (888) (5,161) (16,708) (1,037) (23,794)Ending balance net of tax $— $(55,145) $(25,355) $(2,552) $(83,052)Details of amounts reclassified out of accumulated other comprehensive loss for the year ended March 31, 2019 are as follows (in thousands):Details of AOCL Components Amount reclassified from AOCL Affected line item on consolidated statement of operations Net pension amount unrecognized $2,189 (1) 2,189 Total before tax (630) Tax benefit $1,559 Net of tax Change in derivatives qualifying as hedges $23 Cost of products sold (1,111) Interest expense (25,024) Foreign currency (26,112) Total before tax 8,132 Tax benefit $(17,980) Net of tax(1)These accumulated other comprehensive loss components are included in the computation of net periodic pension cost.
