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 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 September 30, 2015 , the results of its operations for the three and six month periods ended September 30, 2015 and September 30, 2014 , and cash flows for the six months ended September 30, 2015 and September 30, 2014 , have been included. Results for the period ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending March 31, 2016 . The balance sheet at March 31, 2015 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. generally accepted accounting principles 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, 2015 . The Company is a leading designer, marketer and manufacturer of material handling products and services which efficiently and safely move, lift, position and secure material. Key products include hoists, rigging tools, cranes, and actuators. On September 2, 2015, the Company acquired 100% of the shares of Magnetek, Inc. (“Magnetek”), which is a global provider of digital power control systems that are used to control motion and power primarily in material handling, elevator, and mining applications. 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 six month periods ended September 30, 2015 , approximately 60% of sales were to customers in the United States.

Business Combination, Step Acquisition [Abstract]
Acquisitions	Acquisitions On December 30, 2014 the Company acquired 100% of the outstanding common shares of Stahlhammer Bommern GmbH (“STB”) located in Hamm, Germany, a privately-owned company with annual sales of approximately $16,000,000 . STB manufactures a large range of lifting tools and forged parts that are able to withstand particularly heavy, static and dynamic loads, including single and ramshorn lifting hooks. The Company believes STB is a strong strategic fit allowing further expansion of the rigging business globally. The results of STB are included in the Company’s consolidated financial statements from the date of acquisition. The acquisition of STB is not considered significant to the Company’s consolidated financial position and results of operations. The acquisition of STB was funded with existing cash. The purchase price has been preliminarily allocated to the assets acquired and liabilities assumed as of the date of acquisition. The excess consideration of $7,818,000 has preliminarily been recorded as goodwill. The identifiable intangible assets acquired include customer relationships of $2,957,000 , trademark and trade names of $1,301,000 , non-compete agreements of $221,000 , backlog of $74,000 , and patents of $82,000 . During the six month period ending September 30, 2015, the Company has increased the value of its customer relationships by $1,227,000 and decreased the liability for contingent consideration by $810,000 due to modifications made during the measurement period. Both of these adjustments have reduced goodwill at September 30, 2015 by $1,669,000 and increased long term deferred tax liabilities by $368,000 as of the opening balance sheet date. The weighted average life of the acquired identifiable intangible assets subject to amortization was estimated at 9 years at the time of acquisition. Goodwill recorded in connection with the acquisition is not deductible for income tax purposes. The terms of the acquisition require the Company to pay additional consideration to the seller if certain performance measures are met by STB. The potential additional consideration ranges from $0 to $3,681,000 . The Company had preliminarily estimated the fair value of the liability related to this contingent consideration to be $982,000 at March 31, 2015. The Company has adjusted this preliminary estimate to $172,000 during the six months ended September 30, 2015. This liability is included in the Company's consolidated balance sheet within other non-current liabilities. The value has been estimated by simulating the future performance of STB in a Geometric Brownian Motion model. Key assumptions used in this model include a volatility factor of 45% and a credit risk adjusted discount rate of 3% . External acquisition related costs totaling $150,000 were expensed in fiscal 2015. The preliminary assignment of purchase consideration to the assets acquired and liabilities assumed is as follows (in thousands): Working capital $ 9,444 Property, plant and equipment 13,616 Intangible assets 4,561 Other long term assets 67 Debt (6,487 ) Other liabilities (3,596 ) Goodwill 7,818 Total $ 25,423 At September 30, 2015 the Company revalued the contingent consideration based on updated performance forecasts. Based on this revaluation, the liability related to the contingent consideration has been reduced to $13,000 with the resulting gain recorded in cost of products sold on the Company's Condensed Consolidated Statements of Operations and Retained Earnings for the six months ended September 30, 2015. In connection with the acquisition of STB, the Company withheld $5,431,000 to be paid to the seller upon satisfaction of certain conditions. Of this amount, $5,431,000 and $822,000 is expected to be paid to the seller within one year of the periods ending September 30, 2015 and March 31, 2015, respectively. At March 31, 2015, $4,609,000 was expected to be paid to the seller in a time period exceeding one year. The Company has recorded assets on its condensed consolidated balance sheets of $5,431,000 and $822,000 within prepaid expenses and other at September 30, 2015 and March 31, 2015, respectively. Long term restricted cash of $4,609,000 is recorded in other assets at March 31, 2015. Further, the Company has recorded a short term liability to the seller of $5,431,000 and $822,000 within accrued liabilities at September 30, 2015 and March 31, 2015, respectively. A long term liability to the seller of $4,609,000 is recorded within other non current liabilities at March 31, 2015. On September 2, 2015, the Company completed its acquisition of Magnetek, a designer and manufacturer of digital power and motion control solutions for material handling, elevators, and mining applications with annual sales of approximately $112,000,000 . The transaction combines Magnetek's technology with the Company's broad line of lifting and positioning mechanical products to create a more comprehensive solution for customers. In connection with the acquisition, the Company completed a tender offer to acquire all of the outstanding shares of common stock of Magnetek at a purchase price of $50.00 per share in cash for a total acquisition value of $182,467,000 , net of cash acquired. The results of Magnetek included in the Company’s consolidated financial statements from the date of acquisition are net sales and loss from operations of $10,088,000 and $(592,000) , respectively. Magnetek's loss from operations includes acquisition related severance costs of $2,300,000 . These costs have been included in general and administrative expenses. Acquisition expenses incurred by the Company total $5,332,000 through September 30, 2015 and have been recorded in general and administrative expenses. In preparation for the Magnetek acquisition, on July 26, 2015 the Company, JPMorgan Chase Bank, N.A. (“JP Morgan Chase Bank”) and J.P. Morgan Securities LLC entered into a commitment letter in which JPMorgan Chase Bank committed to extend $75,000,000 of incremental revolving commitments to the Company’s existing credit agreement dated as of January 23, 2015. The incremental revolving commitment are on terms and conditions consistent with the Company’s existing revolving credit facility under the Credit Agreement. The Company drew upon its revolving credit facilities to fund the purchase price and fees associated with the acquisition of Magnetek. Revolver borrowings totaled $195,000,000 of which $15,000,000 had been repaid by end of the quarter ending September 30, 2015. The purchase price has been preliminarily allocated to the assets acquired and liabilities assumed as of the date of acquisition. The excess consideration of $54,782,000 has preliminarily been recorded as goodwill. The identifiable intangible assets acquired include customer relationships of $51,700,000 , engineered drawings of $28,494,000 , trademark and trade names of $26,600,000 , patents and technology of $10,060,000 , and in-process research and development of $160,000 . The weighted average life of the acquired identifiable intangible assets subject to amortization was estimated at 18 years at the time of acquisition. Goodwill recorded in connection with the acquisition is not deductible for income tax purposes. The preliminary assignment of purchase consideration to the assets acquired and liabilities assumed is as follows (in thousands): Cash $ 8,205 Working capital 19,276 Property, plant and equipment 6,689 Intangible assets 117,014 Other long term assets 3,796 Other long term liabilities (44,052 ) Deferred taxes, net 24,962 Goodwill 54,782 Total $ 190,672 For the STB and Magnetek acquisitions, goodwill represents future economic benefits arising from other assets acquired that do not meet the criteria for separate recognition apart from goodwill, including assembled workforce, growth opportunities and increased presence in the markets served by the target companies. See Note 3 for assumptions used in valuing of the intangible assets acquired. The following unaudited pro forma financial information presents the combined results of operations as if the acquisition of Magnetek had occurred as of April 1, 2014. The pro forma information includes certain adjustments, including depreciation and amortization expense, interest expense and certain other adjustments, together with related income tax effects. The pro forma amounts may not be indicative of the results that actually would have been achieved had the acquisitions occurred as of April 1, 2014 and are not necessarily indicative of future results of the combined companies (in thousands, except per share data): Three Months Ended Six Months Ended September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Net sales $ 163,902 $ 173,724 $ 326,461 $ 340,531 Net income $ 4,098 $ 11,346 $ 11,762 $ 17,596 Net income per share - Basic $ 0.20 $ 0.57 $ 0.59 $ 0.88 Net income per share - Diluted $ 0.20 $ 0.56 $ 0.58 $ 0.87

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 820 “Fair Value Measurements and Disclosures” establishes the standards for reporting financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value on a recurring basis (at least annually). Under these standards, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants at the measurement date. ASC Topic 820-10-35-37 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the valuation techniques that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is separated into three levels based on the reliability of inputs as follows: Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2 - Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly, involving some degree of judgment. Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The availability of observable inputs can vary and is affected by a wide variety of factors, including the type of asset/liability, whether the asset/liability is established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, assumptions are required to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Company primarily uses readily observable market data in conjunction with internally developed discounted cash flow valuation models when valuing its derivative portfolio and, consequently, the fair value of the Company’s derivatives is based on Level 2 inputs. The carrying amount of the Company's annuity contract 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 sheet. 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 September 30, Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description 2015 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) measured at fair value: Marketable securities $ 18,542 $ 18,542 $ — $ — Annuity contract 3,237 3,237 Derivative Assets (Liabilities): — — Foreign exchange contracts 330 330 Interest rate swap (1,406 ) (1,406 ) Contingent purchase consideration - See Note 2 (13 ) (13 ) Disclosed at fair value: Term loan and revolving credit facility $ (297,324 ) $ — $ (297,324 ) $ — Senior debt (2,002 ) — (2,002 ) — 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 2015 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) measured at fair value: Marketable securities $ 19,867 $ 19,867 $ — $ — Derivative assets (liabilities): Foreign exchange contracts 82 — 82 — Interest rate swap (955 ) — (955 ) — Contingent purchase consideration (982 ) — — (982 ) Disclosed at fair value: Term loan $ (124,442 ) $ — $ (124,442 ) $ — Senior debt (2,270 ) — (2,270 ) — At September 30, 2015, the term loan, revolver borrowings, and senior debt have been recorded at carrying value which approximates fair value. 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 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. Assets and liabilities that were measured on a non-recurring basis during the year ended March 31, 2015 include assets and liabilities acquired in connection with the acquisition STB described in Note 2. The long term debt of STB was measured at fair value and subsequently repaid prior to March 31, 2015. The estimated fair values allocated to the assets acquired and liabilities assumed relied upon fair value measurements based primarily on Level 3 inputs. The valuation techniques used to allocate fair values to working capital items; property, plant, and equipment; and identifiable intangible assets included the cost approach, market approach, and other income approaches. For STB, significant valuation inputs included an attrition rate of 10.0% for customer relationships and a royalty rate of 1.0% for trademark and trade names. Assets and liabilities that were measured on a non-recurring basis during the period ended September 30, 2015 include assets and liabilities acquired in connection with the acquisition Magnetek described in Note 2. The estimated fair values allocated to the assets acquired and liabilities assumed relied upon fair value measurements based primarily on Level 3 inputs. The valuation techniques used to allocate fair values to working capital items; property, plant, and equipment; and identifiable intangible assets included the excess earnings approach, cost approach, relief from royalty approach, and other income approaches. For Magnetek, significant valuation inputs included an attrition rate of 5.0% for customer relationships, a royalty rate of 2.5% for trademark and trade names, a royalty rate ranging from 3.5% to 5.0% for patented technology, engineering costs of $70.00 per hour and obsolescence factors ranging from 0% to 80% for engineered drawings, and a weighted average cost of capital of 11.6% . Additional assets and liabilities that were measured on a non-recurring basis during fiscal 2015 include the net assets of the Company’s Rest of Products. These measurements have been used to test goodwill for impairment on an annual basis under the provisions of ASC Topic 350-20-35-1 “Intangibles, Goodwill and Other – Goodwill Subsequent Measurement.” During fiscal 2015, Step 1 of the goodwill impairment test consisted of determining a fair value of the Company’s Rest of Products reporting unit. 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 of its Rest of Products reporting unit, 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 3.8% . 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 reporting units was determined to be 10.1% based upon an analysis of similar companies and their debt to equity mix, their related volatility and the size of their market capitalization.

An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. 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.

Marketable Securities [Abstract]
Marketable Securities	Marketable Securities All of the Company’s marketable securities, which consist of equity securities and fixed income securities, have been classified as available-for-sale securities and are therefore recorded at their fair values with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive loss in the shareholders’ equity section of the condensed consolidated balance sheet unless unrealized losses are deemed to be other-than-temporary. In such instances, the unrealized losses are reported in the condensed consolidated statements of operations and retained earnings within investment income. 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 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 products liability insurance claims filed through CM Insurance Company, Inc., a wholly owned captive insurance subsidiary. The marketable securities are not available for general working capital purposes. In accordance with ASC Topic 320-10-35-30 “Investments – Debt & Equity Securities – Subsequent Measurement,” the Company reviews its marketable securities for declines in market value that may be considered other-than-temporary. The Company generally considers market value declines to be other-than-temporary if there are declines for a period longer than six months and in excess of 20% of original cost, or when other evidence indicates impairment. We also consider the nature of the underlying investments, our intent and ability to hold the investments until their market values recover, and other market conditions in making this assessment. There were no other-than-temporary impairments for the three and six months ended September 30, 2015 or September 30, 2014 . During the three and six months ended September 30, 2014, investments that were previously written down were sold at a gain of $58,000 . There were no such gains or losses recorded for the three and six months ended September 30, 2015. The following is a summary of available-for-sale securities at September 30, 2015 (in thousands): Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Marketable securities $ 18,789 $ 124 $ 371 $ 18,542 The aggregate fair value of investments and unrealized losses on available-for-sale securities in an unrealized loss position at September 30, 2015 are as follows (in thousands): Aggregate Fair Value Unrealized Losses Securities in a continuous loss position for less than 12 months $ 5,902 $ 306 Securities in a continuous loss position for more than 12 months 4,124 65 $ 10,026 $ 371 The Company considered the nature of the investments, causes of previous impairments, the severity and duration of unrealized losses and other factors and determined that the unrealized losses at September 30, 2015 were temporary in nature. Net realized gains related to sales of marketable securities were $226,000 and $305,000 , in the three month periods ended September 30, 2015 and September 30, 2014 , respectively and $233,000 and $329,000 for the six month periods ended, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is not amortized but is tested for impairment at least annually, in accordance with the provisions of ASC Topic 350-20-35-1. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. The fair value of a reporting unit is determined using a discounted cash flow methodology. The Company’s reporting units are determined based upon whether discrete financial information is available and reviewed regularly, whether those units constitute a business, and the extent of economic similarities 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 September 30, 2015 and March 31, 2015. Only two of the four reporting units carried goodwill at September 30, 2015 and March 31, 2015 . The Duff-Norton reporting unit (which designs, manufactures and sources mechanical and electromechanical actuators and rotary unions) had goodwill of $9,607,000 and $9,563,000 at September 30, 2015 and March 31, 2015, respectively, and the Rest of Products reporting unit (representing the hoist, chain, and forgings design, manufacturing, and distribution businesses) had goodwill of $166,207,000 and $111,898,000 at September 30, 2015 and March 31, 2015, respectively. Both STB and Magnetek have been determined to be a part of the Rest of Products reporting unit. When we evaluate the potential for goodwill impairment, we assess a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for our products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a two-step impairment test. The Company performed its qualitative assessment as of February 28, 2015 for the Duff Norton reporting unit and determined that it was not more likely than not that the fair value of this reporting unit was less than that its applicable carrying value. Accordingly, the Company did not perform the two-step goodwill impairment test for the Duff Norton reporting unit. In accordance with ASC Topic 350-20-35-3, the measurement of impairment of goodwill consists of two steps. In the first step, the Company compares the fair value of each reporting unit to its carrying value. As part of the impairment analysis, the Company determines the fair value of each of its reporting units with goodwill using the income approach and market approach. The income approach uses a discounted cash flow methodology to determine fair value. This methodology recognizes value based on the expected receipt of future economic benefits. Key assumptions in the income approach include a free cash flow projection, an estimated discount rate, a long-term growth rate and a terminal value. These assumptions are based upon the Company’s historical experience, current market trends and future expectations. The Company performed step one of the two-step impairment test for the Rest of Products reporting unit as of February 28, 2015. Based on the results of the two-step impairment test, the Company determined that the Rest of Products reporting unit's fair value was not less than its applicable carrying value. Future impairment indicators, such as declines in forecasted cash flows, may cause additional significant 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. Identifiable intangible assets acquired in a business combination are amortized over their estimated useful lives. A summary of changes in goodwill during the three months ended September 30, 2015 is as follows (in thousands): Balance at April 1, 2015 $ 121,461 STB purchase accounting adjustment - See Note 2 (1,669 ) Acquisition of Magnetek - See Note 2 54,782 Currency translation 1,240 Balance at September 30, 2015 $ 175,814 Goodwill is recognized net of accumulated impairment losses of $107,000,000 as of September 30, 2015 and March 31, 2015, respectively. There were no goodwill impairment losses recorded in the three and six month periods ended September 30, 2015 and 2014. Identifiable intangible assets are summarized as follows (in thousands): September 30, 2015 March 31, 2015 Gross Carrying Amount Accumulated Amortization Net Gross Carrying Amount Accumulated Amortization Net Trademark $ 5,380 $ (2,242 ) $ 3,138 $ 4,656 $ (1,657 ) $ 2,999 Indefinite lived trademark 28,985 — 28,985 2,338 — $ 2,338 Customer relationships 68,978 (8,732 ) 60,246 15,653 (7,442 ) 8,211 Acquired technology 43,705 (527 ) 43,178 4,960 (218 ) $ 4,742 Other 1,440 (558 ) 882 1,251 (437 ) 814 Total $ 148,488 $ (12,059 ) $ 136,429 $ 28,858 $ (9,754 ) $ 19,104 A description of the intangible assets acquired in the Magnetek acquisition during fiscal year 2016 can be found in Note 2. The Company’s intangible assets that are considered to have finite lives are amortized. The weighted-average amortization periods are 18 years for trademarks, 17 years for customer relationships, 18 years for acquired technology, 11 years for other, and 18 years in total. Trademarks with a book value of $28,985,000 have an indefinite useful life and are therefore not being amortized. Total amortization expense was $994,000 and $576,000 for the three month periods ended September 30, 2015 and 2014, respectively. Total amortization expense was $1,587,000 and $1,165,000 for the six month periods ended September 30, 2015 and 2014, respectively. Based on the current amount of identifiable intangible assets, the estimated amortization expense is approximately $3,800,000 for fiscal year 2016 and approximately $4,900,000 for each of the fiscal years 2017 through 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company uses derivative instruments to manage selected foreign currency and interest rate exposures. The Company does not use derivative instruments for speculative trading purposes. All derivative instruments must be recorded on the balance sheet at fair value. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is recorded as accumulated other comprehensive gain (loss), or “AOCL,” and is reclassified to earnings when the underlying transaction has an impact on earnings. The ineffective portion of changes in the fair value of the derivative is reported in foreign currency exchange (gain) loss in the Company’s condensed consolidated statement of operations and retained earnings. For derivatives not classified as cash flow hedges, all changes in market value are recorded as a foreign currency exchange (gain) loss in the Company’s condensed consolidated statements of operations and retained earnings. The cash flow effects of derivatives are reported within net cash provided by operating activities. The Company has foreign currency forward agreements in place to offset changes in the value of intercompany loans to foreign subsidiaries due to changes in foreign exchange rates. The notional amount of these derivatives is $2,076,000 and all of the contracts mature by April 30, 2016. These contracts are marked to market each balance sheet date and are not designated as hedges. The Company has foreign currency option agreements to hedge a portion of booked intercompany inventory purchases denominated in a foreign currency. The notional amount of these derivatives is $714,000 and all contracts mature by November 30, 2015. 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 $15,514,000 and all contracts mature within 12 months of September 30, 2015 . From its September 30, 2015 balance of AOCL, the Company expects to reclassify approximately $87,000 out of AOCL during the next 12 months based on the underlying transactions of the sales of the goods purchased. On February 19, 2015, the Company entered into the Term Loan, which has a variable interest rate. The Company's desired capital structure, is comprised of 50-70% of fixed rate long-term debt and 30-50% of variable rate long-term debt. As such, the Company entered into an interest rate swap agreement that is designated as a cash flow hedge to hedge changes in interest expense due to changes in the interest rate of the senior secured term loan. The amortizing interest rate swap matures on February 19, 2020 and has a notional amount of $81,938,000 as of September 30, 2015. The effective portion of the change in fair value of the interest rate swap is reported in AOCL and will be reclassified to interest expense over the life of the underlying debt obligation. The ineffective portion was not material and was recognized in the current period interest expense. From its September 30, 2015 balance of AOCL, the Company expects to reclassify approximately $576,000 out of AOCL during the next 12 months. The Company is exposed to credit losses in the event of non-performance by the counterparty on its financial instruments. The counterparty has an investment grade credit rating. The Company anticipates that this counterparty will be able to fully satisfy their obligations under the contracts. The Company has derivative contracts with one counterparty as of September, 30, 2015. The Company's agreements with its counterparty contain provisions pursuant to which the Company could be declared in default of its derivative obligations. As of September 30, 2015, the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of September 30, 2015, it could have been required to settle its obligations under these agreements at amounts which approximate the September 30, 2015 fair values reflected in the table below. During the six months ended September 30, 2015, the Company was not in default of any of its derivative obligations.

Debt Disclosure [Abstract]
Debt	Debt Through January 23, 2015, the Company had access to borrow funds under a revolving credit facility ("Replaced Revolving Credit Facility"). The Replaced Revolving Credit Facility provided availability up to a maximum of $100,000,000 and had an initial term ending October 31, 2017 . Provided there was no default, the Company can request an increase in the availability of the Replaced Revolving Credit Facility by an amount not exceeding $75,000,000 , subject to lender approval. Commitment fees were payable against the unused portion of the Replaced Revolving Credit Facility based on the applicable rate. Interest on an outstanding borrowing drawn against the revolver was payable at varying rates depending on the type of outstanding borrowing and its associated interest rate plus its associated applicable rate. The two potential interest rates used were either a Base Rate (equivalent to a fluctuating rate per annum equal to the higher of (a) the Federal Funds Rate plus 1/2 of 1%, (b) the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its “prime rate.”, or (c) LIBOR plus 100 basis points) or a Eurocurrency Rate (equivalent to LIBOR plus a Mandatory Cost). The applicable rate was determined based on the pricing grid in the Replaced Revolving Credit Facility which varied based on the Company’s total leverage ratio and borrowing type through January 23, 2015. The mandatory cost was intended to compensate the lenders for the cost of European banking requirements. The Replaced Revolving Credit Facility was secured by all U.S. inventory, receivables, equipment, real property, subsidiary stock (limited to 65% of non-U.S. subsidiaries) and intellectual property. The corresponding credit agreement associated with the Replaced Revolving Credit Facility placed certain debt covenant restrictions on the Company, including certain financial requirements and restrictions on dividend payments, with which the Company was in compliance through January 23, 2015. Key financial covenants included a minimum fixed charge coverage ratio of 1.25 x, a maximum total leverage ratio, net of cash, of 3.50 x and maximum annual capital expenditures of $30,000,000 . Through February 19, 2015, the Company had outstanding $150,000,000 7 7/8% Senior Subordinated Notes due 2019 registered under the Securities Act of 1933, as amended (7 7/8% Notes). The offering price of the notes was 98.545% of par after adjustment for original issue discount. Provisions of the 7 7/8% Notes included, without limitation, restrictions on indebtedness, asset sales, and dividends and other restricted payments. On or after February 1, 2015, the 7 7/8% Notes were redeemable at the option of the Company, in whole or in part, at a redemption price of 103.938% , reducing to 101.969% and 100% on February 1, 2016 and February 1, 2017, respectively and were due February 1, 2019. In the event of a Change of Control (as defined in the indenture for such notes), each holder of the 7 7/8% Notes could require the Company to repurchase all or a portion of such holder’s 7 7/8% Notes at a purchase price equal to 101% of the principal amount thereof. The 7 7/8% Notes were guaranteed by certain existing and future U.S. subsidiaries and are not subject to any sinking fund requirements. On January 23, 2015, the Company, Columbus McKinnon Dutch Holdings 3 B.V. (“BV 3”), and Columbus McKinnon EMEA GmbH (“EMEA GMBH”) as borrowers (collectively referred to as the "Borrowers"), entered into a new credit agreement (the "New Credit Agreement"). The Borrowers entered into a new $150,000,000 New Revolving Credit Facility and established a new $125,000,000 delayed draw senior secured Term Loan. The Company’s Replaced Revolving Credit Facility was terminated in connection with this transaction. Both the New Revolving Credit Facility and the Term Loan have five-year terms maturing in 2020. The New Revolving Credit Facility has an initial term ending January 23, 2020 and the Term Loan has a term ending February 19, 2020. The terms of the New Credit Agreement include the following: • Term Loan: An aggregate $125,000,000 secured term loan facility which requires quarterly principal amortization of 2.5% with the remaining principal due at maturity date. • New Revolving Credit Facility: An aggregate $150,000,000 secured revolving credit facility which includes sublimits for the issuance of standby letters of credit, swingline loans and multi-currency borrowings in certain specified foreign currencies. • Fees and Interest Rates: Commitment fees and interest rates are determined on the basis of either a Eurocurrency rate or a Base rate plus an applicable margin based upon the Company's Total Leverage Ratio (as defined in the New Credit Agreement). • Accordion Feature: Provisions permitting a Borrower from time to time to increase the aggregate amount of the credit facility by up to $75,000,000 , with a minimum increase of $20,000,000 and with additional commitments from the Lenders, as they may agree, or new commitments from financial institutions acceptable to the Administrative Agent and the Company. • Prepayments: Provisions permitting a Borrower to voluntarily prepay either the Term Loan or New Revolving Credit Facility in whole or in part at any time, and provisions requiring certain mandatory prepayments of the Term Loan or New Revolving Credit Facility on the occurrence of certain events which will permanently reduce the commitments under the New Credit Agreement, each without premium or penalty, subject to reimbursement of certain costs of the Lenders. • Reduction of Commitment: A Borrower may irrevocably cancel, in whole or in part, the unutilized portion of the commitments under the New Credit Agreement in excess of any outstanding loans, the stated amount of all outstanding letters of credit and all unreimbursed amounts drawn under any letters of credit. • Covenants: Provisions containing covenants required of the Company and its subsidiaries including various affirmative and negative financial and operational covenants. Key financial covenants include a minimum fixed charge coverage ratio of 1.25 x; a maximum total leverage ratio, net of cash, of 3.50 x (which may be temporarily increased following a material acquisition, which may be elected two times over the course of the New Credit Agreement, (i) if financed by secured debt the total leverage rate as of the end of the fiscal quarter in which such material acquisition occurs and the three fiscal quarters immediately thereafter, shall not be greater than 4.00:1.00 and as of the end of any fiscal quarter thereafter, the total leverage ratio shall not be greater than 3.50:1.00, and (ii) if financed with unsecured or subordinated indebtedness, the total leverage ratio at the end of the fiscal quarter in which such material acquisition occurs and at the end of any fiscal quarter thereafter, shall not be greater than 4.50:1.00, and permit the secured leverage ratio, to be greater than 3.25:1.00), and maximum capital expenditures of $30 million per fiscal year ($40 million following a material acquisition) with the ability to transfer any unused portion of expenditure to the immediately following fiscal year. The New Revolving Credit Facility is secured by all U.S. inventory, receivables, equipment, real property, subsidiary stock (limited to 65% of non-U.S. subsidiaries) and intellectual property. The New Credit Agreement allows, but limits our ability to pay dividends. On February 19, 2015, the Company borrowed $124,442,000 under the Term Loan. The Term Loan proceeds were net of fees paid to the lenders of $558,000 which were accounted for as a debt discount. On February 23, 2015 the Company redeemed all of the outstanding $150 million of the 7 7/8% Notes. The aggregated price paid for the redemption was $156,630,000 , including a 3.938% call premium or $5,907,000 , and $723,000 of accrued interest on the Notes. The redemption was funded by the Term Loan and cash on hand. The cost of bond redemption on the Company's consolidated statements of operations includes the call premium, write-off of previously unamortized deferred financing costs, and other expenses. On September 2, 2015 the Company exercised the $75,000,000 Accordion Feature offered under the New Credit Agreement. The existing Lenders provided additional commitments for the incremental $75,000,000 , bringing the total available borrowing capacity under the New Revolving Credit facility to an aggregate of $225,000,000 . Additionally on September 2, 2015, the Company borrowed $195,000,000 under the New Revolving Credit facility. The proceeds were net of fees paid to the lenders of $943,000 which were accounted for as a debt discount. The company used $188,900,000 of the proceeds to purchase 100% of the stock of Magnetek as described in Note 2. The Company repaid $15,000,000 of the amount borrowed by September 30, 2015. The Company expects to repay an additional $40,000,000 of the amounts borrowed under the New Revolving Credit Facility over the next 12 months. $40,000,000 of the amounts borrowed have been recorded within the current portion of long term debt on the Company's condensed consolidated balance sheet with the remaining balance recorded as long term debt. The outstanding balance of the Term Loan was $118,750,000 as of September 30, 2015. The company made $3,125,000 of scheduled principal payments during the quarter ended September 30, 2015 and $6,250,000 during the six months ended September 30, 2015. The unused portion of the New Revolving Credit Facility totaled $39,036,000 net of outstanding borrowings of $180,000,000 and outstanding letters of credit of $5,964,000 as of September 30, 2015. The outstanding letters of credit at September 30, 2015 consisted of $1,659,000 in commercial letters of credit and $4,305,000 of standby letters of credit. The gross balances of deferred financing costs were $1,825,000 as of September 30, 2015 and March 31, 2015. The accumulated amortization balances were $243,000 and $61,000 as of September 30, 2015 and March 31, 2015 respectively. On June 22, 2007, the Company recorded a capital lease resulting from the sale and partial leaseback of its facility in Charlotte, NC under a 10 year lease agreement. The Company also has capital leases on certain production machinery and equipment. The outstanding balance on the capital lease obligations of $2,002,000 and $2,270,000 as of September 30, 2015 and March 31, 2015 respectively, are included in senior debt in the consolidated balance sheets. Unsecured and uncommitted lines of credit are available to meet short-term working capital needs for certain of our subsidiaries operating outside of the U.S. The lines of credit are available on an offering basis, meaning that transactions under the line of credit will be on such terms and conditions, including interest rate, maturity, representations, covenants and events of default, as mutually agreed between our subsidiaries and the local bank at the time of each specific transaction. As of September 30, 2015 , unsecured credit lines totaled approximately $8,047,000 , of which $0 was drawn. In addition, unsecured lines of $9,108,000 were available for bank guarantees issued in the normal course of business of which $4,080,000 was utilized.

Magnetek's Plan provides benefits to certain current and former employees of Magnetek. Future benefits under Magnetek's Plan have been frozen since 2003. As of September 2, 2015, the benefit obligation was actuarially determined to be $168,855,000 . The fair value of the Magnetek's Plan assets were $127,726,000 resulting in a long term pension liability of $41,129,000 included in other non current liabilities on the Company's condensed consolidated balance sheet. The Company expects to record net periodic pension income for Magnetek's Plan of $1,034,000 from the date of acquisition to March, 31, 2016. The Company currently plans to contribute approximately $5,933,000 to its pension plans in fiscal 2016. Starting in fiscal 2016, the Company changed the amortization period of its largest plan to the average remaining lifetime of inactive participants as a significant portion of the plan population is now inactive. This change increases the amortization period of the unrecognized gains and losses.

Stock options and performance shares with respect to 133,000 common shares for the three month period ended September 30, 2014 and 272,000 and 130,000 common shares for the six month periods ended September 30, 2015 and 2014, respectively were not included in the computation of diluted earnings per share for September 30, 2015 and 2014 because they were antidilutive. For the three and six months ended September 30, 2015 an additional 77,000 in contingently issuable shares were not included in the computation of diluted earnings per share because a performance condition had not yet been met. On July 26, 2010, the shareholders of the Company approved the 2010 Long Term Incentive Plan (“LTIP”). The Company grants share based compensation to eligible participants under the LTIP. The total number of shares of common stock with respect to which awards may be granted under the plan is 1,250,000 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. In connection with the acquisition of Magnetek, the Company agreed to continue the 2014 Stock Incentive Plan of Magnetek, Inc. (the "Magnetek Stock Plan"). In doing so, the Company has available under the Magnetek Stock Plan 397,602 of the Company's shares which can be granted to certain employees as stock based compensation. During the first six months of fiscal 2016 and 2015, a total of 10,665 and 62,816 shares of stock were issued upon the exercising of stock options related to the Company’s stock option plans. During the fiscal year ended March 31, 2015, 91,000 shares of restricted stock units vested and were issued. On October 26, 2015 the Company's Board of Directors declared a dividend of $0.04 per common share. The dividend will be paid on November 23, 2015 to shareholders of record on November 13, 2015. The dividend payment is expected to be approximately $800,000 . During fiscal 2015, the final quarterly loan payment was made by the Employee Stock Ownership Plan (ESOP) to the Company. There are no shares of collateralized common stock related to the ESOP loan outstanding at September 30, 2015.

Loss Contingencies

Loss Contingency [Abstract]
Loss Contingencies	Loss Contingencies 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 $6,700,000 and $11,200,000 using actuarial parameters of continued claims for a period of 37 years from September 30, 2015 . 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 $7,091,000 , which has been reflected as a liability in the consolidated financial statements as of September 30, 2015 . 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 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 $4,087,000 , which has been reflected as a liability in the consolidated financial statements as of September 30, 2015 . 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. In connection with the acquisition of Magnetek, the following loss contingencies have been assumed by the Company: 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 $1,523,000 which has been reflected as a liability in the consolidated financial statements at September 30, 2015. Litigation-Other In October 2010, Magnetek received a request for indemnification from Power-One, Inc. ("Power-One") for an Italian tax matter arising out of the sale of Magnetek's power electronics business to Power-One in October 2006. With a reservation of rights, Magnetek affirmed its obligation to indemnify Power-One for certain pre-closing taxes. The sale included an Italian company, Magnetek, S.p.A., and its wholly owned subsidiary, Magnetek Electronics (Shenzhen) Co. Ltd. (the “Power-One China Subsidiary”). The tax authority in Arezzo, Italy, issued a notice of audit report in September 2010 wherein it asserted that the Power-One China Subsidiary had its administrative headquarters in Italy with fiscal residence in Italy and, therefore, is subject to taxation in Italy. In November 2010, the tax authority issued a notice of tax assessment for the period of July 2003 to June 2004, alleging that taxes of approximately $2,100,000 (Euro $1,900,000) were due in Italy on taxable income earned by the Power-One China Subsidiary during this period. In addition, the assessment alleges potential penalties together with interest in the amount of approximately $2,900,000 (Euro $2,600,000) for the alleged failure of the Power-One China Subsidiary to file its Italian tax return. The Power-One China Subsidiary filed its response with the provincial tax commission of Arezzo, Italy in January 2011. The tax authority in Arezzo, Italy issued a tax inspection report in January 2011 for the periods July 2002 to June 2003 and July 2004 to December 2006 claiming that the Power-One China Subsidiary failed to file Italian tax returns for the reported periods. A hearing before the Tax Court was held in July 2012 on the tax assessment for the period of July 2003 to June 2004. In September 2012, the Tax Court ruled in favor of the Power-One China Subsidiary dismissing the tax assessment for the period of July 2003 to June 2004. In February 2013, the tax authority filed an appeal of the Tax Court's September 2012 ruling. The Regional Tax Commission of Florence heard the appeal of the tax assessment dismissal for the period of July 2003 to June 2004 and thereafter issued its ruling finding in favor of the tax authority. Magnetek believes the court’s decision was based upon erroneous interpretations of the applicable law and appealed the ruling to the Italian Supreme Court in April 2015. In August 2012, the tax authority in Arezzo, Italy issued notices of tax assessment for the periods July 2002 to June 2003 and July 2004 to December 2006, alleging that taxes of approximately $7,500,000 (Euro $6,700,000) were due in Italy on taxable income earned by the Power-One China Subsidiary together with an allegation of potential penalties in the amount of approximately $3,100,000 (Euro $2,800,000) for the alleged failure of the Power-One China Subsidiary to file its Italian tax returns. On June 3, 2015, the Tax Court ruled in favor of the Power-One China Subsidiary dismissing the tax assessments for the periods of July 2002 to June 2003 and July 2004 to December 2006. On July 27, 2015, the tax authority filed an appeal of the Tax Court's ruling of June 3, 2015. The Company believes it will be successful in its appeal and does not expect to incur a liability related to these tax 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 six months of fiscal year 2016. Magnetek has also been identified by the United States Environmental Protection Agency and certain state agencies as a potentially responsible party for cleanup costs associated with alleged past waste disposal practices at several previously utilized, owned or leased facilities and offsite locations. Its remediation activities as a potentially responsible party were not material in the first six months of fiscal year 2016. 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. The Company has recorded total liabilities of $1,139,000 for all environmental matters in the consolidated financial statements as of September 30, 2015. 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 $500,000 , included in the amount specified above, related to the Bridgeport facility, representing the best estimate of future site investigation costs and remediation costs which are expected to be incurred in the future. FOL's inability to satisfy its remaining obligations to the state of Connecticut related to the Bridgeport facility and any offsite disposal locations, or the discovery of additional environmental contamination at the Bridgeport facility could have a material adverse effect on Magnetek's financial position, cash flows or results of operations.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense as a percentage of income from continuing operations before income tax expense was 111% and 21% in the quarters ended September 30, 2015 and September 30, 2014 , respectively and 55% and 26% for the six-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. For the three and six months ended September 30, 2015, income taxes as a percentage of income before income taxes was higher than our projected rate for fiscal 2016 due to the effect of recording a deferred tax asset valuation allowance on the deferred tax assets of certain foreign subsidiaries of the Company. The effect of recording this valuation allowance resulted in an additional $1,997,000 of income tax expense for the three and six months ended September 30, 2015 and increased the effective tax rate by 51 and 14 percentage points for these same periods, respectively. For the three and six months ended September 30, 2014 income taxes as a percentage of income before income taxes was lower than our annual rate due to a tax regulation newly enacted in the prior year that resulted in the utilization of certain tax credits relating to previous fiscal years. The credits resulted in an income tax benefit of $1,431,000 for the three and six months ended September 30, 2014 and reduced the effective tax rate by 11 and 6 percentage points, respectively. We estimate that the effective tax rate related to continuing operations will be approximately 38% to 42% for fiscal 2016. The estimated fiscal year effective tax rate has increased from June 30, 2015 due to recording of the valuation allowance discussed above, and certain nondeductible expenses related to the acquisition of Magnetek.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Effects of New Accounting Pronouncements	Effects of New Accounting Pronouncements In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." The update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. The adjustments related to previous reporting periods since the acquisition date must be disclosed by income statement line item either on the face of the income statement or in the notes. The ASU is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2015. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11 (“ASU 2015-11”), “Simplifying the Measurement of Inventory”. ASU 2015-11 requires an entity to measure inventory that is within the scope of this ASU at the lower of cost and net realizable value. Existing impairment models will continue to be used for inventories that are accounted for using the last-in first-out (“LIFO”) method. ASU 2015-11 requires prospective adoption for inventory measurements for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. In June 2015, the FASB issued ASU No. 2015-10, "Technical Corrections and Updates." The amendments in this update cover a wide range of topics in the codification and are generally categorized as follows: Amendments Related to Differences between Original Guidance and the Codification; Guidance Clarification and Reference Corrections; Simplification; and, Minor Improvements. The amendments are effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2015. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. In May 2015, the FASB issued ASU 2015-08, "Business Combinations (Topic 805): Pushdown Accounting - Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115." The amendments in the ASU amend various SEC paragraphs included in the FASB’s Accounting Standards Codification to reflect the issuance of Staff Accounting Bulletin No. 115, or SAB 115. SAB 115 rescinds portions of the interpretive guidance included in the SEC’s Staff Accounting Bulletins series and brings existing guidance into conformity with ASU No. 2014-17, Business Combinations (Topic 805): Pushdown Accounting, which provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. We have adopted the amendments in ASU 2015-08 as the amendments in the update are effective upon issuance. The adoption of this standard did not have a significant effect on the Company's consolidated financial statements. In May 2015, the FASB issued ASU No. 2015-07, "Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)." The ASU provides guidance on the disclosures for investments in certain entities that calculate net asset value (NAV) per share (or its equivalent). The amendments remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share (or its equivalent) as a practical expedient. ASU No. 2015-07 is to be applied retrospectively and is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those fiscal years, with early application permitted. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement." The ASU provides guidance to entities about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the entity should account for the software license element of the arrangement consistent with the acquisition of other software license. If a cloud computing arrangement does not include a software license, the entity should account for the arrangement as a service contract. The guidance does not change GAAP for an entity's accounting for service contracts. The ASU is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2015. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-04, "Compensation – Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer's Defined Benefit Obligation and Plan Assets." The ASU provides the use of a practical expedient that permits the entity to measure defined benefit plans assets and obligations using the month-end that is closest to the entity's fiscal year-end and apply that practical expedient consistently from year to year. Further, if a contribution or significant event occurs between the month-end date used to measure defined benefit plan asset and obligations and an entity's fiscal year-end, the entity should adjust the measurement of defined plan assets and obligations to reflect of those contributions of significant events. However, an entity should not adjust the measurement of defined benefit plan asset and obligations for other events that occur between the month-end measurement and the entity's fiscal year-end that are not caused by the entity. The amendments are effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2015. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The guidance also requires retrospective application to all prior periods presented. ASU 2015-03 is effective for the first interim period for fiscal years beginning after December 15, 2015. In August 2015, the FASB issued ASU No. 2015-15, “Interest — Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting” (“ASU 2015-15”), which clarifies the treatment of debt issuance costs from line-of-credit arrangements after the adoption of ASU 2015-03. In particular, ASU 2015-15 clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of such arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis." This update is intended to improve certain areas of consolidation guidance by simplifying the consolidation evaluation process, and by placing more emphasis on risk of loss when determining a controlling financial interest. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2015. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40).” ASU 2014-15 addresses management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period." ASU 2014-12 requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures." ASU 2014-11 changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. ASU 2014-11 also requires new disclosures about transfers that are accounted for as sales in transactions that are economically similar to repurchase agreements and increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. This ASU is effective for the first interim or annual period beginning after December 15, 2014. The adoption of this standard did not have a significant effect on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which delays the effective date of ASU 2014-09 by one year. This ASU is now effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 changes the criteria for disposals to qualify as discontinued operations and requires new disclosures about disposals of both discontinued operations and certain other disposals that do not meet the new definition. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2014. The adoption of this standard did not have a significant effect on the Company's consolidated financial statements.

The Company generally considers market value declines to be other-than-temporary if there are declines for a period longer than six months and in excess of 20% of original cost, or when other evidence indicates impairment. We also consider the nature of the underlying investments, our intent and ability to hold the investments until their market values recover, and other market conditions in making this assessment.
