Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position of Columbus McKinnon Corporation (the Company) at December 31, 2018 , the results of its operations for the three and nine month periods ended December 31, 2018 and December 31, 2017 , and cash flows for the nine months ended December 31, 2018 and December 31, 2017 , have been included. Results for the period ended December 31, 2018 are not necessarily indicative of the results that may be expected for the year ending March 31, 2019 . The balance sheet at March 31, 2018 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Columbus McKinnon Corporation annual report on Form 10-K for the year ended March 31, 2018 . The Company is a leading global designer, manufacturer and marketer of hoists, actuators, rigging tools, digital power control systems, and other material handling products, which efficiently and safely move, lift, position, and secure materials. Key products include hoists, rigging tools, crane components, actuators, digital power control and delivery systems, elevator application drive systems, and explosion-protected hoists. The Company’s material handling products are sold globally, principally to third party distributors through diverse distribution channels, and to a lesser extent directly to end-users. During the three and nine month periods ended December 31, 2018 , approximately 53% and 54% of sales, respectively, were to customers in the United States.

Business Combination, Step Acquisition [Abstract]
Acquisitions	2. Acquisitions and Disposals 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. 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 "Held for Sale Businesses") as they are 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, described below. During the quarter ended December 31, 2018, the Company continued to actively pursue the sale of the remaining two Held for Sale Businesses and expects the sale of each business to occur in fiscal 2019. As such, the businesses continue to meet the criteria as being held for sale as of December 31, 2018 in accordance with Accounting Standards Codification (“ASC”) 360-10-45-9, "Property, Plant, and Equipment." The businesses are not deemed significant to be considered discontinued operations. When businesses or assets 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 $1,103,000 during the three months ended December 31, 2018 . An impairment loss has been recorded on the remaining held for sale businesses in the amount of $27,753,000 during the nine months ended December 31, 2018 , of which $16,653,000 was recorded during the three months ended December 31, 2018 . The third quarter impairment loss of $16,653,000 included a $9,835,000 reduction to property, plant, and equipment and a $6,818,000 reduction to inventory. Both the gain and impairment loss were recorded in Net loss on held for sale businesses on the Condensed Consolidated Statements of Operations and Retained Earnings. The impairment loss was recognized to reduce the carrying value of the two remaining held for sale businesses to their current fair values less estimated costs to sell. The amount of the loss was determined based on the fair value calculation described in Note 4. The Company will continue to update the analysis each reporting period as additional information becomes available. Additionally, net sales and pre-tax income for the three Held for Sale Businesses was $8,983,000 and $29,320,000 and $990,000 and $3,106,000 for the three and nine months ended December 31, 2018 and $9,178,000 and $27,824,000 and $(61,000) and $388,000 for the three and nine months ended December 31, 2017 , respectively. The following table represents the carrying amounts of the two businesses classified as held for sale before impairment (in thousands): December 31, 2018 ASSETS: (unaudited) Current assets: Cash and cash equivalents $ 362 Trade accounts receivable 1,796 Inventories 11,084 Prepaid expenses and other 57 Total current assets 13,299 Property, plant, and equipment, net 13,793 Goodwill 7,304 Other intangibles, net 1,810 Deferred taxes on income 211 Total assets $ 36,417 LIABILITIES AND SHAREHOLDER'S EQUITY: Current liabilities: Trade accounts payable $ 929 Accrued liabilities 1,533 Total current liabilities 2,462 Other non current liabilities 1,932 Total liabilities 4,394 Total shareholder's equity 32,023 Total liabilities and shareholder's equity $ 36,417 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. $200,000 is included in Cost of Products sold on the Condensed Consolidated Statements of Operations and Retained Earnings during the three months ended December 31, 2018 related to the plant closure.

Revenue Recognition [Abstract]
Revenue from Contract with Customer [Text Block]	3. Revenue Recognition Transition In May 2014, the Financial Accounting Standards Board (“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 for the three and nine months ended December 31, 2018 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 information 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 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. 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, the Company determined that while there is no alternative use for most custom engineered products, the Company 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, 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 Condensed Consolidated Balance Sheets. When the related performance obligation is satisfied and revenue is recognized, the contract liability is released into income. The following table illustrates the balance and related activity for customer advances in the nine months ending December 31, 2018 (in thousands): Customer advances (contract liabilities) March 31, 2018, beginning balance 15,909 Additional customer advances received 32,552 Revenue recognized from customer advances (36,024 ) Other (1) (1,081 ) December 31, 2018, ending balance $ 11,356 (1) Other includes the impact of foreign currency translation As of December 31, 2018 , 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 December 31, 2018 . 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 three and nine months ending December 31, 2018 (in thousands): Three Months Ended Nine Months Ended Net Sales by Product Grouping December 31, 2018 December 31, 2018 Industrial Products $ 92,073 $ 287,809 Crane Solutions $ 93,190 $ 280,333 Engineered Products $ 23,512 $ 61,659 All other $ 8,640 $ 29,748 Total $ 217,415 $ 659,549 Industrial products include: manual chain hoists, electrical chain hoists, rigging/ clamps, industrial winches, and high capacity hooks. Crane solutions products include: wire rope hoists, drives and controls, crane kits and components, jib cranes, and workstations. Engineered products include: linear and mechanical actuators, lifting tables, rail projects, and actuations systems. The All other product grouping primarily includes: tire shredders, overhead bridge, jib and gantry cranes, and other standard motion control products. 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 Condensed 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.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB 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 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 acquired in connection with the acquisition of Magnetek 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 Condensed Consolidated Balance Sheets. The carrying value of the Company’s Term Loan and senior debt approximate fair value based on current market interest rates for debt instruments of similar credit standing and, consequently, their fair values are based on Level 2 inputs. The following table provides information regarding financial assets and liabilities measured or disclosed at fair value (in thousands): Fair value measurements at reporting date using December 31, Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description 2018 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) measured at fair value: Marketable securities $ 6,951 $ 6,951 $ — $ — Annuity contract 2,255 — 2,255 — Derivative Assets (Liabilities): Foreign exchange contracts 131 — 131 — Interest rate swap asset 2,869 — 2,869 — Cross currency swap liability (22,319 ) — (22,319 ) — Cross currency swap asset 2,408 — 2,408 — Disclosed at fair value: Term loan $ (317,325 ) $ — $ (317,325 ) $ — Fair value measurements at reporting date using March 31, Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description 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 ) $ — The Company does not have any non-financial assets and liabilities that are recognized at fair value on a recurring basis. At December 31, 2018 , the Term loan has 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. During fiscal 2019 , the Company terminated certain employees in connection with its overall STAHL CraneSystems ("STAHL") integration plan. For the nine months ended December 31, 2018 the Company incurred $1,602,000 in severance and other employee termination costs, all of which were incurred in the first quarter. The costs incurred were calculated at fair value on a non-recurring basis using Level 3 inputs which included expected payments. Of the severance and other termination costs previously accrued, $516,000 is unpaid at December 31, 2018 and included within accrued liabilities on the Company's Condensed Consolidated Balance Sheet. As described in Note 2, the Company has classified the assets and liabilities of certain businesses as held for sale. As a result of this classification during the first quarter of fiscal 2019, 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 Step 1 goodwill impairment test. The interim Step 1 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 Step 1 goodwill impairment test for the Rest of Products reporting unit did not indicate that goodwill was impaired. The Company is required to record assets and liabilities of its Held for Sale Businesses at the lower of their carrying amount or fair value less cost to sell. For the purposes of this analysis, fair value is based on the estimated selling price of the assets held for sale. Based on this analysis, the Company recorded a $27,753,000 impairment charge on its Held for Sale Businesses during the first nine months of fiscal 2019, of which $16,653,000 was recorded during the three months ended December 31, 2018. The additional impairment charge recorded during the three months ended December 31, 2018 was due to a further reduction in the estimated selling price of the assets held for sale. The impairment charge was offset by a gain on the completed sale of the Company's Tire Shredder business of $1,103,000 as presented on the Condensed Consolidated Statements of Operations and Retained Earnings. Refer to Note 2 for additional details. Please refer to the 2018 10-K for a full description of the assets and liabilities measured on a non-recurring basis that are included in the Company's March 31, 2018 balance sheet.

Accordingly, interim LIFO calculations must necessarily be based on management's estimates of expected year-end inventory levels and costs. Because these are subject to many factors beyond management's control, estimated interim results are subject to change in the final year-end LIFO inventory valuation. Net inventories were reduced $2,258,000 and $6,818,000 at December 31, 2018 as a result of the sale of the Tire Shredder business and the impairment of inventory at the remaining held for sale businesses, both of which occurred during the three months ended December 31, 2018 , respectively. Refer to Note 2 for additional details.

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 accounting) 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 Condensed Consolidated Statements of Operations and Retained Earnings. The Company adopted this standard on a modified retrospective basis. A cumulative effect adjustment 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 for unrealized gains and losses were losses of $422,000 and $317,000 in the three and nine months ended December 31, 2018 . Consistent with prior periods, the estimated fair value is based on quoted market prices at the balance sheet dates. The cost of securities sold is based on the specific identification method. Interest and dividend income are included in Investment (income) loss in the Condensed Consolidated Statements of Operations and Retained Earnings. Marketable securities are carried as long-term assets since they are held for the settlement of the Company’s general and product 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 not material in the three and nine months ended December 31, 2017 . 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 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 $230,000 and $402,000 in the three and nine months ended December 31, 2018 , respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill and indefinite lived trademarks are not amortized but are 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 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.” The Company has four reporting units as of December 31, 2018 and March 31, 2018 . Only two of the four reporting units carried goodwill at December 31, 2018 and March 31, 2018 . The Duff-Norton reporting unit (which designs, manufactures and sources mechanical and electromechanical actuators and rotary unions) had goodwill of $9,636,000 and $9,721,000 at December 31, 2018 and March 31, 2018 , respectively, and the Rest of Products reporting unit (representing the hoist, chain, forgings, digital power, motion control, manufacturing, and distribution businesses) had goodwill of $317,215,000 and $337,713,000 at December 31, 2018 and March 31, 2018 , respectively. Refer to the 2018 10-K for information regarding our annual goodwill and indefinite lived trademark impairment evaluation. Future impairment indicators, such as declines in forecasted cash flows, may cause impairment charges. Impairment charges could be based on such factors as the Company’s stock price, forecasted cash flows, assumptions used, control premiums or other variables. As described in Note 2, the Company has classified the assets and liabilities of certain businesses as held for sale. As a result of this classification during fiscal 2019 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. This analysis was performed during the first quarter of fiscal 2019. The net assets of the Rest of Products reporting unit were measured on a non-recurring basis in order to perform a Step 1 goodwill impairment test. The interim Step 1 goodwill impairment test for Rest of Products did not indicate that goodwill was impaired. The Company is required to record assets and liabilities of its Held for Sale Businesses at the lower of their carrying amount or fair value less cost to sell. Based on this analysis, the Company recorded a $27,753,000 impairment charge on its Held for Sale Businesses during the nine months ended December 31, 2018 , of which $6,174,000 was recorded as a reduction to goodwill during the first quarter of fiscal 2019. No additional reduction to goodwill was recorded during the third quarter. A summary of changes in goodwill during the nine months ended December 31, 2018 is as follows (in thousands): Balance at April 1, 2018 $ 347,434 Held for Sale Impairment (see Note 2) (6,174 ) Currency translation (14,409 ) Balance at December 31, 2018 $ 326,851 Goodwill is recognized net of accumulated impairment losses of $113,174,000 and $107,000,000 as of December 31, 2018 and March 31, 2018 , respectively. The increase at December 31, 2018 relates to the assets held for sale as described above. Identifiable intangible assets acquired in a business combination are amortized over their estimated useful lives. Identifiable intangible assets are summarized as follows (in thousands): December 31, 2018 March 31, 2018 Gross Carrying Amount Accumulated Amortization Net Gross Carrying Amount Accumulated Amortization Net Trademark $ 6,338 $ (4,149 ) $ 2,189 $ 5,875 $ (3,299 ) $ 2,576 Indefinite lived trademark 47,403 — 47,403 48,874 — 48,874 Customer relationships 185,386 (33,311 ) 152,075 199,045 (27,887 ) 171,158 Acquired technology 46,777 (9,694 ) 37,083 46,898 (7,436 ) 39,462 Other 3,454 (2,752 ) 702 3,936 (2,242 ) 1,694 Total $ 289,358 $ (49,906 ) $ 239,452 $ 304,628 $ (40,864 ) $ 263,764 Customer relationships with a gross carrying amount of $2,815,000 and accumulated amortization of $957,000 have been written off during the first nine months of fiscal 2019, in connection with the $27,753,000 impairment charge on the Held for Sale Businesses described above. Further, other intangible assets with a gross carrying amount of $226,000 and accumulated amortization of $211,000 have also been written off during the first nine months of fiscal 2019 as a result of the assets held for sale. The Company’s intangible assets that are considered to have finite lives are amortized. The weighted-average amortization periods are 14 years for trademarks, 18 years for custom er relationships, 18 years for acquired technology, 6 y ears for other, and 18 y ears in total. Trademarks with a carrying value of $47,403,000 as of December 31, 2018 have an indefinite useful life and are therefore not being amortized. Total amortization expense was $3,701,000 and $3,908,000 for the three month periods ended December 31, 2018 and 2017 , respectively. Total amortization expense was $11,358,000 and $11,547,000 for the nine month periods ended December 31, 2018 and 2017 , respectively. Based on the current amount of identifiable intangible assets and current exchange rates, the estimated annual amortization expense is approximately $15,000,000 for fiscal years 2019 through 2023.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	8. 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 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 foreign currency derivatives not designated as cash flow hedges, all changes in market value are recorded as a foreign currency exchange loss (gain) 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 December 31, 2018 . 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 December 31, 2018 , the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of December 31, 2018 , it could have been required to settle its obligations under these agreements at amounts which approximate the December 31, 2018 fair values reflected in the table below. During the nine months ended December 31, 2018 , the Company was not in default of any of its derivative obligations. As of December 31, 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 $202,478,000 , and all of the contracts mature by January 31, 2022. From its December 31, 2018 balance of AOCL, the Company expects to reclassify approximately $1,001,000 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 $3,460,000 , and all of the contracts mature by March 31, 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 $11,896,000 and all contracts mature by December 31, 2019. From its December 31, 2018 balance of AOCL, the Company expects to reclassify approximately $99,000 out of AOCL during the next 12 months based on the expected 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 $209,828,000 as of December 31, 2018 . 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. The ineffective portion was not material and was recognized in current period interest expense. From its December 31, 2018 balance of AOCL, the Company expects to reclassify approximately $892,000 out of AOCL, and into interest expense, during the next 12 months.

Stock options and performance shares with respect to 131,000 common shares for the nine months ended December 31, 2018 were not included in the computation of diluted earnings per share because they were antidilutive. Stock options, restricted stock units, and performance shares with respect to 1,393,000 common shares for the three months ended December 31, 2017 were not included in the computation of diluted loss per share because they were antidilutive as a result of the Company's net loss attributed to the enactment of the Tax Cuts and Jobs Act (the Act). For the nine months ended December 31, 2017, 68,000 common shares were excluded because they were antidilutive. For the three and nine months ended December 31, 2018 , an additional 153,000 contingently issuable shares were not included in the computation of diluted earnings per share because a performance condition had not yet been met. For the three and nine months ended December 31, 2017 an additional 127,000 in contingently issuable shares were not included in the computation of diluted earnings per share because a performance condition had not yet been met. During fiscal 2017, the shareholders of the Company approved the 2016 Long Term Incentive Plan (“2016 LTIP”). 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 2016 LTIP 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.

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 the 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 $13,487,000 as of December 31, 2018 , of which $9,913,000 is included in Other non current liabilities and $3,574,000 included in Accrued liabilities. The liability for accrued general and product liability costs are funded in part by investments in marketable securities (see Note 6). The per occurrence limits on the self-insurance for general and product liability coverage to the Company 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. 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 December 31, 2018 a total of $889,000 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 December 31, 2018 . 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 $5,877,000 , which has been reflected as a liability in the consolidated financial statements as of December 31, 2018 . 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 of $430,000 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 $6,253,000 , which has been reflected as a liability in the consolidated financial statements as of December 31, 2018 . 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 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 $944,000 which has been reflected as a liability in the consolidated financial statements at December 31, 2018 . 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 $2,200,000 (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 $3,000,000 (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 $7,700,000 (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 $3,200,000 (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 the first nine months of 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 off-site locations. Its remediation activities as a potentially responsible party were not material in the first nine months of 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 $163,000 at December 31, 2018 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 $293,000 for all environmental matters related to Magnetek in the consolidated financial statements as of December 31, 2018 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 December 31, 2018 the Company has recorded a reserve of $168,000 for legal costs incurred to date and expected to be incurred related to this matter.

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes Income tax expense as a percentage of income from continuing operations before income tax expense was 134% and 213% in the quarters ended December 31, 2018 and December 31, 2017 , respectively, and 29% and 65% for the nine-month periods then ended, respectively. Typically these percentages vary from the U.S. statutory rate primarily due to varying effective tax rates at the Company's foreign subsidiaries, and the jurisdictional mix of taxable income for these subsidiaries. Income tax expense as a percentage of income from continuing operations for the three and nine months ended December 31, 2018 were increased by 215% and 15% , respectively, as a result of recording a valuation allowance against deferred tax assets in connection with the impairment loss on held for sale assets described in Note 2. Additionally, income tax expense as a percentage of income from continuing operations for the three and nine months ended December 31, 2018 was decreased by 100% and 7% , respectively, as a result of the reversal of valuation allowances in certain foreign jurisdictions and the final accounting for the one-time transition tax pursuant to Staff Accounting Bulletin No. 118 ("SAB 118"), as discussed below. Income tax expense as a percentage of income from continuing operations for the three and nine months ended December 31, 2017 were increased by 200 and 48 percentage points, respectively, as a result of accounting for the enactment of the Tax Cuts and Jobs Act on December 22, 2017 (the "Act"). The Company estimates that the effective tax rate related to continuing operations will be approximately 27% to 29% for fiscal 2019 . SAB 118 measurement period 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, one-time transition tax, and tax on global intangible low-taxed income. At December 31, 2018, we have now completed our accounting for all of the enactment-date income tax effects of the Act. 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 from continuing operations in the third quarter 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 three months ended December 31, 2018. No further adjustments were made to this provisional amount during the measurement period. Global intangible low-taxed income (GILTI) 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, 2018, or during the three months ended December 31, 2018. We have included the effect of the current year GILTI tax in our annual effective tax rate. Refer to the Company’s consolidated financial statements included in its 2018 10-K for further information on income taxes.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Effects of New Accounting Pronouncements	Effects of New Accounting Pronouncements 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. 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. We continue to gather lease agreements in order to maintain a complete list and are in process of developing key estimates required upon adoption. We are currently evaluating the impact that the standard will have on our consolidated financial statements. Information about our undiscounted future lease payments and the timing of those payments is included in Note 17 of our 2018 10-K. 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, 2021, including interim periods within those fiscal years. 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. Therefore, the Company adopted this rule during the quarter ended December 31, 2018. See the Condensed Consolidated Statement of Stockholders' Equity. 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 three or nine months ended as of December 30, 2018. 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. We are currently evaluating the impact the standard will have on our consolidated financial statements. 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 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 $463,000 and $1,251,000 on the Condensed Consolidated Statements of Operations and Retained Earnings for the three and nine months ended December 31, 2017. 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 10. 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. 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 Condensed Consolidated Balance Sheets that agree to the total of the amount presented in the Condensed Consolidated Statements of Cash Flows (in thousands): December 31, 2018 December 31, 2017 Cash and cash equivalents at end of period, shown in the Condensed Consolidated Balance Sheets $ 58,079 $ 64,598 Restricted cash within Prepaid expenses and other — 294 Restricted cash within Other assets 250 250 Total Cash, cash equivalents, and restricted cash at end of period, shown in the Condensed Consolidated Statements of Cash Flows $ 58,329 $ 65,142 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 Condensed 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 6 for additional information.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Policy Text Block]	In May 2014, the Financial Accounting Standards Board (“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 for the three and nine months ended December 31, 2018 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	8. 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 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 foreign currency derivatives not designated as cash flow hedges, all changes in market value are recorded as a foreign currency exchange loss (gain) 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 December 31, 2018 . 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 December 31, 2018 , the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of December 31, 2018 , it could have been required to settle its obligations under these agreements at amounts which approximate the December 31, 2018 fair values reflected in the table below. During the nine months ended December 31, 2018 , the Company was not in default of any of its derivative obligations. As of December 31, 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 $202,478,000 , and all of the contracts mature by January 31, 2022. From its December 31, 2018 balance of AOCL, the Company expects to reclassify approximately $1,001,000 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 $3,460,000 , and all of the contracts mature by March 31, 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 $11,896,000 and all contracts mature by December 31, 2019. From its December 31, 2018 balance of AOCL, the Company expects to reclassify approximately $99,000 out of AOCL during the next 12 months based on the expected 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 $209,828,000 as of December 31, 2018 . 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. The ineffective portion was not material and was recognized in current period interest expense. From its December 31, 2018 balance of AOCL, the Company expects to reclassify approximately $892,000 out of AOCL, and into interest expense, during the next 12 months.

Revenue from Contract with Customer [Text Block]	3. Revenue Recognition Transition In May 2014, the Financial Accounting Standards Board (“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 for the three and nine months ended December 31, 2018 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 information 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 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. 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, the Company determined that while there is no alternative use for most custom engineered products, the Company 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, 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 Condensed Consolidated Balance Sheets. When the related performance obligation is satisfied and revenue is recognized, the contract liability is released into income. The following table illustrates the balance and related activity for customer advances in the nine months ending December 31, 2018 (in thousands): Customer advances (contract liabilities) March 31, 2018, beginning balance 15,909 Additional customer advances received 32,552 Revenue recognized from customer advances (36,024 ) Other (1) (1,081 ) December 31, 2018, ending balance $ 11,356 (1) Other includes the impact of foreign currency translation As of December 31, 2018 , 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 December 31, 2018 . 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 three and nine months ending December 31, 2018 (in thousands): Three Months Ended Nine Months Ended Net Sales by Product Grouping December 31, 2018 December 31, 2018 Industrial Products $ 92,073 $ 287,809 Crane Solutions $ 93,190 $ 280,333 Engineered Products $ 23,512 $ 61,659 All other $ 8,640 $ 29,748 Total $ 217,415 $ 659,549 Industrial products include: manual chain hoists, electrical chain hoists, rigging/ clamps, industrial winches, and high capacity hooks. Crane solutions products include: wire rope hoists, drives and controls, crane kits and components, jib cranes, and workstations. Engineered products include: linear and mechanical actuators, lifting tables, rail projects, and actuations systems. The All other product grouping primarily includes: tire shredders, overhead bridge, jib and gantry cranes, and other standard motion control products. 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 Condensed 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.
