| Accounting Policies [Abstract] | ' | ' |
| Cash and Cash Equivalents, Policy [Policy Text Block] | ' | ' |
| Cash Equivalents |
| Cash equivalents consist of highly liquid investments with a maturity of three months or less at the time of purchase. Fair value of cash equivalents approximates carrying value. |
| Receivables, Policy [Policy Text Block] | ' | ' |
| Trade and Other Receivables, net |
| Trade and other receivables are recorded net of an allowance for doubtful accounts. Trade and other receivables include amounts billed and currently due from customers, amounts currently due but unbilled, certain estimated contract changes and amounts retained by the customer pending contract completion. Unbilled amounts are generally billed and collected within one year. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company records the allowance for doubtful accounts based on prior experience and for specific collectibility matters when they arise. The Company writes off balances against the reserve when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. |
| Trade and other receivables, net comprised of the following: |

| Inventory, Policy [Policy Text Block] | ' | ' |
| Inventories |
| The Company records inventories at the lower of cost (average-cost or specific-identification methods) or market. Costs on long-term contracts and programs in progress represent recoverable costs incurred for production or contract-specific facilities and equipment, allocable operating overhead and advances to suppliers. Pursuant to contract provisions, agencies of the U.S. Government and certain other customers have title to, or a security interest in, inventories related to such contracts as a result of advances, performance-based payments, and progress payments. The Company reflects those advances and payments as an offset against the related inventory balances. The Company expenses general and administrative costs related to products and services provided essentially under commercial terms and conditions as incurred. The Company determines the costs of inventories by the first-in, first-out or average cost methods. |
| Work-in-process inventory includes capitalized pre-production costs. Company policy allows for the capitalization of pre-production costs after it establishes a contractual arrangement with a customer that explicitly states that the cost of recovery of pre-production costs is allowed. |
| Customer Advances and Progress Payments for Long-term Contracts or Programs [Policy Text Block] | ' | ' |
| Advance Payments and Progress Payments |
| Advance payments and progress payments received on contracts-in-process are first offset against related contract costs that are included in inventory, with any excess amount reflected in current liabilities under the Accrued expenses caption within the accompanying Consolidated Balance Sheets. |
| Property, Plant and Equipment, Policy [Policy Text Block] | ' | ' |
| Property and Equipment |
| Property and equipment, which includes equipment under capital lease and leasehold improvements, are recorded at cost and depreciated over the estimated useful lives of the related assets, or the lease term if shorter in the case of leasehold improvements, by the straight-line method. Buildings and improvements are depreciated over a period of 15 to 39.5 years, and machinery and equipment are depreciated over a period of 7 to 15 years (except for furniture, fixtures and computer equipment which are depreciated over a period of 3 to 10 years). |
| Goodwill and Intangible Assets, Policy [Policy Text Block] | ' | ' |
| Goodwill and Intangible Assets |
| The Company accounts for purchased goodwill and intangible assets in accordance with Accounting Standards Codification ("ASC") 350, Intangibles—Goodwill and Other. Under ASC 350, purchased goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives. Upon acquisition, critical estimates are made in valuing acquired intangible assets, which include but are not limited to: future expected cash flows from customer contracts, customer lists, and estimating cash flows from projects when completed; tradename and market position, as well as assumptions about the period of time that customer relationships will continue; and discount rates. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from the assumptions used in determining the fair values. |
| The Company's operating segments of Aerostructures, Aerospace Systems and Aftermarket Services are also its reporting units. The Chief Executive Officer and the Chief Financial Officer comprise the Company's Chief Operating Decision Maker ("CODM"). The Company's CODM evaluates performance and allocates resources based upon review of segment information. Each of the operating segments is comprised of a number of operating units which are considered to be components. The components, for which discrete financial information exists, are aggregated for purposes of goodwill impairment testing. The Company's acquisition strategy is to acquire companies that complement and enhance the capabilities of the operating segments of the Company. Each acquisition is assigned to either the Aerostructures reporting unit, the Aerospace Systems reporting unit or the Aftermarket Services reporting unit. The goodwill that results from each acquisition is also assigned to the reporting unit to which the acquisition is allocated, because it is that reporting unit which is intended to benefit from the synergies of the acquisition. |
| The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed using a two-step approach required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit. |
| The first step of the quantitative test is to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further work is required and no impairment loss is recognized. If the carrying amount exceeds the fair value, then the second step is required to be completed, which involves allocating the fair value of the reporting unit to each asset and liability, with the excess being applied to goodwill. An impairment loss occurs if the amount of the recorded goodwill exceeds the implied goodwill. The determination of the fair value of our reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. We are required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments. |
| When performing the two-step quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses, and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of our reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. |
| We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal years 2014, 2013 or 2012. In the fourth quarter of fiscal 2014, the Company chose to perform the quantitative assessment, in lieu of the qualitative assessment for each of the Company's three reporting units, which indicated that the fair value of the reporting unit exceeded its carrying amount, including goodwill. |
| As of March 31, 2014 and 2013, the Company had a $438,400 indefinite-lived intangible asset associated with the tradenames acquired in the acquisitions of Vought Aircraft Industries, Inc. ("Vought") and Embee Inc. ("Embee"). The Company assesses whether indefinite-lived intangible assets impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If based on this qualitative assessment, the Company determines it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed to determine whether an indefinite-lived intangible asset impairment exists. We test the indefinite-lived intangible assets for impairment by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess of the carrying value over the amount of fair value is recognized as an impairment. |
| We incurred no impairment of indefinite-lived intangible assets as a result of our annual indefinite-lived intangible assets impairment tests in fiscal years 2014, 2013 or 2012. In the fourth quarter of fiscal 2014, the Company chose to perform the quantitative assessment, in lieu of the qualitative assessment, for each of the Company's indefinite-lived intangible assets, which indicated that the fair value of the indefinite-lived intangible assets exceeded its carrying amount. |
| Finite-lived intangible assets are amortized over their useful lives ranging from 5 to 32 years. The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Intangible assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the carrying amount is less than the estimated fair value, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset. |
| During the fiscal year ended March 31, 2012, a $2,870 fair value adjustment was recorded due to the reduction of the fair value of a contingent earnout liability associated with a prior acquisition due to changes in the projected earnings over the respective earnout periods. The Company also considered these changes in projected earnings to be an indicator of impairment of the long-lived assets directly related to this acquisition and, as a result, tested these long-lived assets for recoverability and concluded that the asset group was recoverable. For the fiscal years ended March 31, 2014, 2013 and 2012, exclusive of the charges recorded in connection with the assets held for sale, there were no reductions to the remaining useful lives and no write-downs of long-lived assets, including intangible assets, were required. |
| Deferred Charges, Policy [Policy Text Block] | ' | ' |
| Deferred Financing Costs |
| Financing costs are deferred and amortized to Interest expense and other in the accompanying Consolidated Statements of Income over the related financing period using the effective interest method or the straight-line method when it does not differ materially from the effective interest method. Deferred financing costs, net of accumulated amortization of $19,499 and $22,906, respectively, are recorded in Other, net in the accompanying Consolidated Balance Sheets as of March 31, 2014 and 2013. Make-whole payments in connection with early debt retirements are classified as cash flows used in financing activities. |
| Acquired Contract Liabilities, net [Policy Text Block] | ' | ' |
| Acquired Contract Liabilities, net |
| In connection with the acquisition of Vought, the Company assumed existing long-term contracts. Based on a review of these contracts, the Company concluded that the terms of certain contracts were either more or less favorable than could be realized in market transactions as of the date of the acquisition. As a result, the Company recognized acquired contract liabilities, net of acquired contract assets of $124,548 at the acquisition date of Vought based on the present value of the difference between the contractual cash flows of the executory contracts and the estimated cash flows had the contracts been executed at the acquisition date. The liabilities principally relate to long-term life of program contracts that were initially executed by Vought over 15 years ago, as well as loss contracts for which Vought had recognized significant pre-acquisition contract loss reserves. |
| In connection with the acquisition of GPECS, the Company assumed existing long-term contracts. Based on a review of these contracts, the Company concluded that the terms of certain contracts were either more or less favorable than could be realized in market transactions as of the date of the acquisition. As a result, the Company recognized acquired contract liabilities, net of acquired contract assets of $113,117 at the acquisition date of GPECS based on the present value of the difference between the contractual cash flows of the executory contracts and the estimated cash flows had the contracts been executed at the acquisition date. The liabilities principally relate to long-term life of program contracts that were initially executed by GPECS 5 to 8 years ago. |
| In connection with the acquisition of Primus Composites ("Primus"), the Company assumed existing long-term contracts. Based on a review of the long-term contracts of Primus, the Company concluded that the terms of certain contracts to be either more or less favorable than could be realized in market transactions as of the date of the acquisition. As a result, the Company recognized provisional acquired contract liabilities, net of acquired contract assets of $26,280 at the acquisition date based on the present value of the difference between the contractual cash flows of the executory contracts and the estimated cash flows had the contracts been executed at the acquisition date. The net liabilities principally relate to long-term life of program contracts were initially executed by Primus 5 to 8 years ago. |
| The Company measured these net liabilities under the measurement provisions of ASC 820, Fair Value Measurements and Disclosures, which is based on the price to transfer the obligation to a market participant at the measurement date, assuming that the net liabilities will remain outstanding in the marketplace. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each long-term contracts can materially impact our results of operations. |
| The acquired contract liabilities, net for Vought, GPECS and Primus are being amortized as non-cash revenues over the terms of the respective contracts. The Company recognized net amortization of contract liabilities of $42,629, $25,457 and $26,684 in the fiscal years ended March 31, 2014, 2013 and 2012, respectively, and such amounts have been included in revenues in results of operations. The balance of the liability as of March 31, 2014 is $141,505 and, based on the expected delivery schedule of the underlying contracts, the Company estimates annual amortization of the liability as follows: 2015—$30,775; 2016—$26,914; 2017—$21,596; 2018—$16,772; and 2019—$17,055. |
| Revenue Recognition | ' | ' |
| Revenue Recognition |
| Revenues are generally recognized in accordance with the contract terms when products are shipped, delivery has occurred or services have been rendered, pricing is fixed or determinable, and collection is reasonably assured. The Company's policy with respect to sales returns and allowances generally provides that the customer may not return products or be given allowances, except at the Company's option. Accruals for sales returns, other allowances and estimated warranty costs are provided at the time of shipment based upon past experience. |
| A significant portion of the Company's contracts are within the scope of ASC 605-35, Revenue—Construction-Type and Production-Type Contracts, and revenue and costs on contracts are recognized using the percentage-of-completion method of accounting. Accounting for the revenue and profit on a contract requires estimates of (1) the contract value or total contract revenue, (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract's scope of work and (3) the measurement of progress towards completion. Depending on the contract, the Company measures progress toward completion using either the cost-to-cost method or the units-of-delivery method, with the great majority measured under the units-of-delivery method. |
| | | | | | | |
| • | Under the cost-to-cost method, progress toward completion is measured as the ratio of total costs incurred to estimated total costs at completion. Costs are recognized as incurred. Profit is determined based on estimated profit margin on the contract multiplied by progress toward completion. Revenue represents the sum of costs and profit on the contract for the period. | | | | | | |
| | | | | | | |
| • | Under the units-of-delivery method, revenue on a contract is recorded as the units are delivered and accepted during the period at an amount equal to the contractual selling price of those units. The costs recorded on a contract under the units-of-delivery method are equal to the total costs at completion divided by the total units to be delivered. As contracts can span multiple years, the Company often segments the contracts into production lots for the purposes of accumulating and allocating cost. Profit is recognized as the difference between revenue for the units delivered and the estimated costs for the units delivered. | | | | | | |
| Adjustments to original estimates for a contract's revenues, estimated costs at completion and estimated total profit are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur. These estimates are also sensitive to the assumed rate of production. Generally, the longer it takes to complete the contract quantity, the more relative overhead that contract will absorb. The impact of revisions in cost estimates is recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period in which they become probable ("forward losses") and are first offset against costs that are included in inventory, with any remaining amount reflected in accrued contract liabilities in accordance with ASC 605-35. Revisions in contract estimates, if significant, can materially affect results of operations and cash flows, as well as valuation of inventory. Furthermore, certain contracts are combined or segmented for revenue recognition in accordance with ASC 605-35. |
| For the fiscal year ended March 31, 2014, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year decreased operating income, net income and earnings per share by approximately $(53,166), $(35,121) and $(0.67), respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2014 included gross favorable adjustments of approximately $14,341 and gross unfavorable adjustments of approximately $(67,507). For the fiscal year ended March 31, 2013, cumulative catch-up adjustments resulting from changes in estimates decreased operating income, net income and earnings per share by approximately $(14,560), $(9,350) and $(0.18), respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2013 included gross favorable adjustments of approximately $15,913 and gross unfavorable adjustments of approximately $(30,473). For the fiscal year ended March 31, 2012, cumulative catch-up adjustments resulting from changes in estimates increased operating income, net income and earnings per share by approximately $18,264 $11,755 and $0.23, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2012 included gross favorable adjustments of approximately $29,549 and gross unfavorable adjustments of approximately $(11,285). |
| Amounts representing contract change orders or claims are only included in revenue when such change orders or claims have been settled with the customer and to the extent that units have been delivered. Additionally, some contracts may contain provisions for revenue sharing, price re-determination, requests for equitable adjustments, change orders or cost and/or performance incentives. Such amounts or incentives are included in contract value when the amounts can be reliably estimated and their realization is reasonably assured. |
| Although fixed-price contracts, which extend several years into the future, generally permit the Company to keep unexpected profits if costs are less than projected, the Company also bears the risk that increased or unexpected costs may reduce profit or cause the Company to sustain losses on the contract. In a fixed-price contract, the Company must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs the Company will incur in performing these contracts and in projecting the ultimate level of revenue that may otherwise be achieved. |
| Failure to anticipate technical problems, estimate delivery reductions, estimate costs accurately or control costs during performance of a fixed-price contract may reduce the profitability of a fixed-price contract or cause a loss. The Company believes that it has recognized adequate provisions in the financial statements for losses on fixed-price contracts, but cannot be certain that the contract loss provisions will be adequate to cover all actual future losses. |
| While the Company is currently projecting its recurring production contracts to be profitable, there is still a substantial amount of risk similar to what the Company has experienced on certain programs. Particularly, the Company's ability to manage risks related to supplier performance, execution of cost reduction strategies, hiring and retaining skilled production and management personnel, quality and manufacturing execution, program schedule delays and many other risks, will determine the ultimate performance of these programs. |
| For example, significant cost growth experienced on the 747-8 program during fiscal 2014 resulted in lower than expected margins during the year, but the current year deliveries were still profitable. We have assessed the profitability of future production related to the 747-8 program and currently project that the program will continue to be profitable. However, if significant cost growth is experienced and cost reduction strategies are not successfully implemented, profit margin on the 747-8 program could continue to deteriorate or a loss might be incurred on future recurring production blocks. |
| Included in net sales of the Aerostructures and Aerospace Systems group is the non-cash amortization of acquired contract liabilities recognized as fair value adjustments through purchase accounting of various acquisitions. For the fiscal years ended March 31, 2014, 2013 and 2012, the Company recognized $42,629, $25,457 and $26,684, respectively, in net sales in the accompanying Consolidated Statements of Income. |
| The Aftermarket Services Group provides repair and overhaul services, certain of which services are provided under long-term power-by-the-hour contracts, comprising approximately 5% of the segment's net sales. The Company applies the proportional performance method to recognize revenue under these contracts. Revenue is recognized over the contract period as units are delivered based on the relative value in proportion to the total estimated contract consideration. In estimating the total contract consideration, management evaluates the projected utilization of its customer's fleet over the term of the contract, in connection with the related estimated repair and overhaul servicing requirements to the fleet based on such utilization. Changes in utilization of the fleet by customers, among other factors, may have an impact on these estimates and require adjustments to estimates of revenue to be realized |
| Shipping and Handling Cost, Policy [Policy Text Block] | ' | ' |
| Shipping and Handling Costs |
| The cost of shipping and handling products is included in cost of products sold |
| Research and Development Expense, Policy [Policy Text Block] | ' | ' |
| Research and Development Expense |
| Research and development expense (which includes certain amounts subject to reimbursement from customers) was approximately $61,657, $61,270 and $50,116 for the fiscal years ended March 31, 2014, 2013 and 2012, respectively |
| Pension and Other Postretirement Plans, Nonpension Benefits, Policy [Policy Text Block] | ' | ' |
| Retirement Benefits |
| Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension income (expense) is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension income (expense). The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset gains (losses) affects the calculated value of plan assets and, ultimately, future pension income (expense). |
| The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service. |
| Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable. |
| As required under ASC 715, Compensation - Retirement Benefits, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs. |
| At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency |
| Fair Value of Financial Instruments, Policy [Policy Text Block] | ' | ' |
| Fair Value Measurements |
| Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its interest rate swap (see Note 10) and to its pension and postretirement plan assets (see Note 15) |
| Foreign Currency Transactions and Translations Policy [Policy Text Block] | ' | ' |
| Foreign Currency Translation |
| The determination of the functional currency for the Company's foreign subsidiaries is made based on appropriate economic factors. The functional currency of the Company's subsidiaries Triumph Aviation Services—Asia and Triumph Structures—Thailand is the U.S. dollar since that is the currency in which that entity primarily generates and expends cash. The functional currency of the Company's remaining subsidiaries is the local currency, since that is the currency in which those entities primarily generate and expend cash. Assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resultant translation adjustments are included in accumulated other comprehensive income (see Note 13). Gains and losses arising from foreign currency transactions of these subsidiaries are included in net income |
| Income Tax, Policy [Policy Text Block] | ' | ' |
| Income Taxes |
| The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized. The Company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes in its consolidated statements of income |
| Description of New Accounting Pronouncements Not yet Adopted [Text Block] | ' | ' |
| Recently Issued Accounting Pronouncements |
| In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2013-11 ("ASU") 2013-11, Presentation of Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). ASU 2013-11 provides that a liability related to an unrecognized tax benefit would be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. In that case, the liability associated with the unrecognized tax benefit is presented in the financial statements as a reduction to the related deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. The provisions of ASU 2013-11 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of the provisions of ASU 2013-11 is not expected to have a material impact on the Company's consolidated financial statements. |
| In February 2013, The FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 201-02"). ASU 2013-02 amended ASC 220 to require companies to report, in one place, information about reclassifications out of other comprehensive income (loss) to net income by their respective income statement line item. For items not reclassified to net income in their entirety, the Company is required to reference other disclosures that provide greater detail about these reclassifications. The Company adopted the guidance effective April 1, 2013. Other than the additional disclosures, the adoption of the guidance did not have an impact on the Company's financial statements. |
| In July 2012,The FASB issued authoritative guidance included in ASC Topic 350. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is impaired, as a basis for determining whether it is necessary to perform the quantitative impairment test described in FASB ASC Topic 350. The Company elected to early adopt the guidance for the annual impairment test performed during the year ended March 31, 2013. This guidance did not have a material impact on the Company's consolidated balance sheets, statements of income, or statements of cash flows. |
| Stock-Based Compensation | ' | ' |
| Stock-Based Compensation |
| The Company recognizes compensation expense for share-based awards based on the fair value of those awards at the date of grant. Stock-based compensation expense for fiscal years ended March 31, 2014, 2013 and 2012 was $4,653, $6,367 and $4,988, respectively. The benefits of tax deductions in excess of recognized compensation expense were $39, $4,628 and $1,880 for fiscal years ended March 31, 2014, 2013 and 2012, respectively. Included in the stock-based compensation for fiscal years ended March 31, 2014 and 2013, is $0 and $1,649, respectively, classified as a liability as of March 31, 2014 and 2013 associated with each year's grant. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to employees. Upon the exercise of stock options or vesting of restricted stock, the Company first transfers treasury stock, then will issue new shares. (see Note 16 for further details. |
| Cash Flow, Supplemental Disclosures [Text Block] | ' | ' |
| Supplemental Cash Flow Information |
