| Nature of Operations and Summary of Significant Accounting Policies | NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations. STERIS Corporation, an Ohio corporation, together with its subsidiaries, develops, manufactures, and markets infection prevention, contamination control, microbial reduction, and procedural support products and services for healthcare, pharmaceutical, scientific, research, industrial, and governmental Customers throughout the world. As used in this annual report, STERIS Corporation and its subsidiaries together are called “STERIS,” the “Company,” “we,” “us,” or “our,” unless otherwise noted. We operate in three reportable business segments: Healthcare, Life Sciences, and STERIS Isomedix Services (“Isomedix”). We describe our operating segments in note 12 titled, "Business Segment Information". Our fiscal year ends on March 31. References in this Annual Report to a particular “year” or “year-end” mean our fiscal year. The significant accounting policies applied in preparing the accompanying consolidated financial statements of the Company are summarized below: Principles of Consolidation. The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. We eliminate inter-company accounts and transactions when we consolidate these accounts. Use of Estimates. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and related notes to financial statements. Actual results could differ from those estimates. On an ongoing basis, we revise the estimates and assumptions as new information becomes available. Cash Equivalents and Supplemental Cash Flow Information. Cash equivalents are all highly liquid investments with a maturity of three months or less when purchased. We invest our excess cash in short-term instruments including money market funds and time deposits with major banks and financial institutions. We select investments in accordance with the criteria established in our investment policy. Our investment policy specifies, among other things, maturity, credit quality and concentration restrictions with the objective of preserving capital and maintaining adequate liquidity. Information supplementing our Consolidated Statements of Cash Flows is as follows:
Revenue Recognition. We recognize revenue for products when ownership passes to the Customer, which is based on contract or shipping terms and for services when the service is provided to the Customer. Our Customers include end users as well as dealers and distributors who market and sell our products. Our revenue is not contingent upon resale by the dealer or distributor. We have no further obligations related to bringing about resale and our standard return and restocking fee policies are applied. Revenues are reported net of sales and value-added taxes collected from Customers. We also have individual Customer contracts that offer discounted pricing. Dealers and distributors may be offered sales incentives in the form of rebates. We reduce revenue for discounts and estimated returns, rebates, and other similar allowances in the same period the related revenues are recorded. Returns, rebates, and similar allowances are estimated based on historical experience and trend analysis. In transactions that contain multiple elements, such as when products, maintenance services, and other services are combined, we recognize revenue as each product is delivered or service is provided to the Customer. We allocate the total arrangement consideration to each element based on its relative fair value, based on the price for the product or service when it is sold separately. We offer preventative maintenance agreements to our Customers with contract terms of one to five years which require us to maintain and repair our products during this time. Amounts received under these Customer contracts are initially recorded as deferred service revenues and then recognized as service revenues ratably over the contract term. Accounts Receivable. Accounts receivable are presented at their face amount, less allowances for sales returns and uncollectible accounts. Accounts receivable consist of amounts billed and currently due from Customers and amounts earned but unbilled. We generally obtain and perfect security interest in products sold in the United States when we have a concern with the Customer's risk profile. We maintain an allowance for uncollectible accounts receivable for estimated losses in the collection of amounts owed by Customers. We estimate the allowance based on analyzing a number of factors, including amounts written off historically, Customer payment practices, and general economic conditions. We also analyze significant Customer accounts on a regular basis and record a specific allowance when we become aware of a specific Customer’s inability to pay. As a result, the related accounts receivable are reduced to an amount that we reasonably believe is collectible. We maintain an allowance for sales returns based upon known returns and estimated returns for both capital equipment and consumables. We estimate returns of capital equipment and consumables based upon recent historical experience less the estimated inventory value of the returned goods. Inventories, net. Inventories are stated at the lower of their cost or market value. We determine cost based upon a combination of the last-in, first-out (“LIFO”) and first-in, first-out (“FIFO”) cost methods. For inventories valued using the LIFO method, we believe that the use of the LIFO method results in a matching of current costs and revenues. Inventories valued using the LIFO method represented approximately 38.6% and 37.7% of total inventories at March 31, 2013 and 2012, respectively. Inventory costs include material, labor, and overhead. If we had used only the FIFO method of inventory costing, inventories would have been $18,944 and $18,158 higher than those reported at March 31, 2013 and 2012, respectively. We review the net realizable value of inventory on an ongoing basis, considering factors such as deterioration, obsolescence, and other items. We record an allowance for estimated losses when the facts and circumstances indicate that particular inventories will not be usable. If future market conditions vary from those projected, and our estimates prove to be inaccurate, we may be required to write-down inventory values and record an adjustment to cost of revenues. Property, Plant, and Equipment. Our property, plant, and equipment consists of land and land improvements, buildings and leasehold improvements, machinery and equipment, information systems, radioisotope (cobalt-60), and construction in progress. Property, plant, and equipment are presented at cost less accumulated depreciation and depletion. We capitalize additions and improvements. Repairs and maintenance are charged to expense as they are incurred. Land is not depreciated and construction in progress is not depreciated until placed in service. Depreciation of most assets is computed on the cost less the estimated salvage value by using the straight-line method over the estimated remaining useful lives. Depletion of radioisotope is computed using the annual decay factor of the material, which is similar to the sum-of-the-years-digits method. We generally depreciate or deplete property, plant, and equipment over the useful lives presented in the following table:
When we sell, retire, or dispose of property, plant, and equipment, we remove the asset’s cost and accumulated depreciation from our Consolidated Balance Sheets. We recognize the net gain or loss on the sale or disposition in the Consolidated Statements of Income in the period when the transaction occurs. Interest. We capitalize interest costs incurred during the construction of long-lived assets. We capitalized interest costs of $585 and $705 for the years ended March 31, 2013 and 2012, respectively. Total interest expense for the years ended March 31, 2013, 2012, and 2011 was $15,675, $12,065, and $12,000, respectively. Identifiable Intangible Assets. Our identifiable intangible assets include product technology rights, trademarks, licenses, and Customer relationships. We record these assets at cost, or when acquired as part of a business acquisition, at estimated fair value. We generally amortize identifiable intangible assets over periods ranging from 5 to 20 years using the straight-line method. Our intangible assets also include indefinite-lived assets including certain trademarks and tradenames that were acquired in fiscal 2013. These assets will be tested periodically for impairment. Investments. Investments in marketable securities are stated at fair value and are included in "Other assets" on the Consolidated Balance Sheets. Unrealized gains and losses on marketable securities classified as available-for-sale are recorded in Accumulated Other Comprehensive Income (Loss). Asset Impairment Losses. Property, plant, equipment, and identifiable intangible assets are reviewed for impairment when indicators of impairment exist and circumstances indicate that the carrying value of such assets may not be recoverable. Impaired assets are recorded at the lower of carrying value or estimated fair value. We conduct this review on an ongoing basis and, if an impairment exists, we record the loss in the Consolidated Statements of Income during that period. Acquisitions of Business. Assets acquired and liabilities assumed in a business combination are accounted for at fair value on the date of acquisition. Costs related to the acquisition are expensed as incurred. Goodwill. We perform our annual impairment test for goodwill in the third quarter of each year. We may consider qualitative indicators of the fair value of a reporting unit when it is unlikely that a reporting unit has impaired goodwill. We may also utilize a discounted cash flow analysis that requires certain assumptions and estimates be made regarding market conditions and our future profitability. In those circumstances we test goodwill for impairment by reviewing the book value compared to the fair value at the reporting unit level. We calculate the fair value of our reporting units based on the present value of estimated future cash flows. Considerable management judgment is necessary to evaluate the impact of operating and macroeconomic changes and to estimate future cash flows to measure fair value. Assumptions used in our impairment evaluations, such as forecasted growth rates and cost of capital, are consistent with internal projections and operating plans. We believe such assumptions and estimates are also comparable to those that would be used by other marketplace participants. SYSTEM 1 Rebate Program. The Accrued SYSTEM 1 Rebate Program (the “Rebate Program”), initially recognized during the first quarter of fiscal 2011, was based upon the quantity of SYSTEM 1 processors eligible for rebates and the estimated value of rebates to be provided upon their return. The rebate portion of the Rebate Program was recognized as contra-revenue consistent with other returns and allowances offered to Customers. The estimated costs to facilitate the disposal of the returned SYSTEM 1 processors was recognized as cost of revenues. Both components were recorded as current liabilities. The key assumptions involved in the estimates associated with the Rebate Program included: the number and age of SYSTEM 1 processors eligible for rebates under the Rebate Program, the number of Customers that would elect to participate in the Rebate Program, the proportion of Customers that would choose each rebate option, and the estimated per unit costs of disposal. The Rebate Program ended August 2, 2012. Customers utilized rebates totaling approximately $66,600 on orders placed since the initiation of the Rebate Program. The costs associated with the Rebate Program were lower than originally estimated because fewer Customers elected to participate in the Rebate Program than anticipated. The remaining recorded accrual is $210 as of March 31, 2013. Self-Insurance Liabilities. We record a liability for self-insured risks that we retain for general and product liabilities, workers’ compensation, and automobile liabilities based on actuarial calculations. We use our historical loss experience and actuarial methods to calculate the liability. This liability includes estimates for both losses and incurred but not reported claims. We review the assumptions used to calculate the estimated liability at least annually to evaluate the adequacy of the amount recorded. We maintain insurance policies to cover losses greater than our estimated liability, which are subject to the terms and conditions of those policies. We are also self-insured for employee medical claims. We estimate a liability for incurred but not reported claims based upon recent claims experience. Benefit Plans. We sponsor defined benefit pension and other post-retirement welfare benefit plans for certain former employees. We determine our costs and obligations related to these plans by evaluating input from third-party professional advisors. These costs and obligations are affected by assumptions including the discount rate, expected long-term rate of return on plan assets, the annual rate of change in compensation for eligible employees, estimated changes in costs of healthcare benefits, and other factors. We review the assumptions used on an annual basis. We recognize an asset for the overfunded status or a liability for the underfunded status of defined benefit pension and post-retirement benefit plans in our consolidated balance sheets. This amount is measured as the difference between the fair value of plan assets and the benefit obligation (the projected benefit obligation for pension plans and the accumulated post-retirement benefit obligation for other post-retirement benefit plans). Changes in the funded status of the plans are recorded in other comprehensive income in the year they occur. We measure plan assets and obligations as of the balance sheet date. We provide additional information about our pension and other post-retirement welfare benefits plans in note 10 to our consolidated financial statements titled, “Benefit Plans.” Fair Value of Financial Instruments. Except for long-term debt, our financial instruments are highly liquid or have short-term maturities. We provide additional information about the fair value of our financial instruments in note 18 titled, “Fair Value Measurements.” Foreign Currency Translation. Most of our operations use their local currency as their functional currency. Financial statements of international subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for revenues, expenses, gains and losses. Translation adjustments for international subsidiaries whose local currency is their functional currency are recorded as a component of accumulated other comprehensive income (loss) within shareholders’ equity. Transaction gains and losses resulting from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency are recognized as incurred in the accompanying Consolidated Statements of Income, except for certain inter-company balances designated as long-term investments. Forward and Swap Contracts. We enter into foreign currency forward contracts to hedge assets and liabilities denominated in foreign currencies, including inter-company transactions. We do not use derivative financial instruments for speculative purposes. These contracts are marked to market, with gains and losses recognized within “Selling, general, and administrative expenses” or "Cost of revenues" in the accompanying Consolidated Statements of Income. Warranty. Warranties are provided on the sale of certain of our products and services and an accrual for estimated future claims is recorded at the time revenue is recognized. We estimate warranty expense based primarily on historical warranty claim experience. Shipping and Handling. We record shipping and handling costs in costs of revenues. Shipping and handling costs charged to Customers are recorded as revenues in the period the product revenues are recognized. Advertising Expenses. Costs incurred for communicating, advertising and promoting our products are generally expensed when incurred as a component of Selling, General and Administrative Expense. We incurred $6,880, $5,857, and $6,013 of advertising costs during the years ended March 31, 2013, 2012, and 2011, respectively. Research and Development. We incur research and development costs associated with commercial products and expense these costs as incurred. If a Customer reimburses us for research and development costs, the costs are charged to the related contracts as costs of revenues. Income Taxes. Our income tax expense includes United States federal, state and local, and foreign income taxes, and is based on reported pre-tax income. We defer income taxes for all temporary differences between pre-tax financial and taxable income and between the book and tax basis of assets and liabilities. We record valuation allowances to reduce net deferred tax assets to an amount that we expect will more-likely-than-not be realized. In making such a determination, we consider all available information, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the valuation allowance which would reduce the provision for income taxes and the effective tax rate. We evaluate uncertain tax positions in accordance with a two-step process. The first step is recognition: The determination of whether or not it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, we presume that the position will be examined by the appropriate tax authority and that the tax authority will have full knowledge of all relevant information. The second step is measurement: A tax position that meets the more-likely-than-not threshold is measured to determine the amount of benefit to recognize in the financial statements. The measurement process requires the determination of the range of possible settlement amounts and the probability of achieving each of the possible settlements. The tax position is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. No tax benefits are recognized for positions that do not meet the more-likely-than-not threshold. Tax positions that previously failed to meet the more-likely-than-not threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which the threshold is no longer met. We describe income taxes further in note 9 to our consolidated financial statements titled, “Income Taxes.” Medical Device Excise Tax. The Medical Device Excise Tax became effective January 1, 2013. The excise tax was mandated by the 2010 health care reform legislation and assesses a 2.3% tax on the sale or use of certain medical devices that are sold or manufactured in the United States. Many of our products are subject to the excise tax. The tax is included in cost of revenues in the period of sale. Share-Based Compensation. We describe share-based compensation in note 15 to our consolidated financial statements titled, “Share-Based Compensation.” We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. We record liability awards at fair value each reporting period and the change in fair value is reflected as share-based compensation expense in our Consolidated Statements of Income. The expense is classified as cost of goods sold, selling, general and administrative expenses or research and development expenses in a manner consistent with the employee’s compensation and benefits. These costs are recognized in the Consolidated Statement of Income over the period during which an employee is required to provide service in exchange for the award. Excess tax benefits realized from the exercise of stock options are reported as a financing cash inflow. Restructuring. We have recognized restructuring expenses as incurred. In addition, the property, plant, and equipment associated with the related facilities were assessed for impairment as performed on an annual basis. Asset impairment and accelerated depreciation expenses primarily relate to inventory write-downs for rationalized products and adjustments in the carrying value of the closed facilities to their estimated fair value. In addition, the remaining useful lives of other property, plant, and equipment associated with the related operations were reevaluated based on the respective restructuring plan, resulting in the acceleration of depreciation and amortization of certain assets. Recently Issued Accounting Standards Impacting the Company In February 2013, the FASB issued an accounting standards update titled "Presentation of Comprehensive Income: Reclassification Out of Accumulated Other Comprehensive Income," amending Accounting Standards Codification ASC Topic 220, "Comprehensive Income". This amended guidance requires an entity to report information about the amounts reclassified out of accumulated other comprehensive income (AOCI) by component. In addition, for significant items reclassified from AOCI to net income in their entirety, during the same reporting period, entities are required to report the effect on the line items on the face of the statement where net income is presented, or in the notes. For significant items that are not classified to net income in their entirety, entities are required to cross-reference to other disclosures that provide additional information about those amounts. The standards update is effective prospectively for fiscal periods beginning after December 15, 2012, with early adoption permitted. We anticipate adoption of the new standard during the first quarter of our fiscal year 2014. The anticipated adoption of this standard is not expected to impact our consolidated financial position, results of operations or cash flows. In July 2012, the FASB issued an accounting standards update titled "Testing Indefinite-Lived Intangible Assets" for Impairment," amending certain sections of Subtopic 350-30 Intangibles-Goodwill and Other-General Intangibles Other than Goodwill. This amended guidance allows an entity to first assess qualitative factors to determine if 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 its qualitative assessment an entity concludes it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, quantitative impairment testing is required. However, if an entity concludes otherwise, quantitative impairment testing is not required. The standards update is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The anticipated adoption of this standard is not expected to impact our consolidated financial position, results of operations or cash flows. In June 2011, the FASB issued an accounting standard update titled "Presentation of Comprehensive Income," amending Accounting Standards Codification ASC Topic 220, "Comprehensive Income." This guidance requires that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance became effective retrospectively for the interim periods and annual periods beginning after December 15, 2011. As required by the standard, Consolidated Statements of Comprehensive Income have been presented. The adoption of this standard did not have an impact on our consolidated financial position, results of operations or cash flows. |

| Restructuring | RESTRUCTURING The following summarizes our restructuring plans announced in prior fiscal years. We recognize restructuring expenses as incurred. In addition, we assess the property, plant and equipment associated with the related facilities for impairment. Fiscal 2010 Restructuring Plan. During the fourth quarter of fiscal 2010 we adopted a restructuring plan primarily related to the transfer of the remaining operations in our Erie, Pennsylvania facility to the U.S. headquarters in Mentor, Ohio and the consolidation of our European Healthcare manufacturing operations into two central locations within Europe (the “Fiscal 2010 Restructuring Plan”). In addition, we rationalized certain products and eliminated certain positions. Since the inception of the Fiscal 2010 Restructuring Plan, we have incurred pre-tax expenses totaling $8,176 related to these actions, of which $7,072 was recorded as restructuring expenses and $1,104 was recorded in cost of revenues. We do not expect to incur any significant additional restructuring expenses related to this plan. These actions are intended to enhance profitability and improve efficiencies. Fiscal 2008 Restructuring Plan. During the fourth quarter of fiscal 2008, we adopted a restructuring plan primarily focused on our North American operations (the “Fiscal 2008 Restructuring Plan”). As part of this plan, we announced the closure of two sales offices and the rationalization of certain products. We also reduced the workforce in certain support functions. Across all of our reporting segments approximately 90 employees, primarily located in North America, were directly impacted. These restructuring actions were designed to enhance profitability and improve efficiency by reducing ongoing operating costs. Since the inception of the Fiscal 2008 Restructuring Plan, we have recorded pre-tax expenses totaling $13,892 of which $10,233 was recorded as restructuring expenses and $3,659 was recorded in cost of revenues. We do not expect to incur any significant additional restructuring expenses related to the Fiscal 2008 Restructuring Plan. The following tables summarize our total pre-tax restructuring expenses for fiscal 2013, fiscal 2012 and fiscal 2011:
(1) Includes $150 in charges recorded in cost of revenues on Consolidated Statements of Income. Liabilities related to restructuring activities are recorded as current liabilities on the accompanying Consolidated Balance Sheets within “Accrued payroll and other related liabilities” and “Accrued expenses and other.” The following table summarizes our liabilities related to these restructuring activities:
(2) Certain amounts reported include the impact of foreign currency movements relative to the U.S. dollar.
(1) Includes curtailment benefit of $1,336 related to International defined benefit plan. Additional information is included in note 10, "Benefit Plans." (2) Certain amounts reported include the impact of foreign currency movements relative to the U.S. dollar. |

| Goodwill and Intangible Assets Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Goodwill | GOODWILL AND INTANGIBLE ASSETS Goodwill is tested annually for impairment. Further, goodwill is reviewed for impairment whenever events or changes in circumstances indicate there may be a possible permanent loss of value. We performed our annual impairment tests for goodwill and indefinite life intangible assets during the third quarter of fiscal 2013. These tests confirmed that the fair value of STERIS’s reporting units and indefinite life intangible assets exceed their respective carrying values and that no impairment loss was required to be recognized in fiscal 2013 or for any prior periods. Future impairment tests will be performed annually in the fiscal third quarter, or sooner if a triggering event occurs. Changes to the carrying amount of goodwill for the years ended March 31, 2013 and 2012 were as follows:
The fiscal 2013 increase in goodwill associated with the Healthcare segment resulted from the acquisitions of United States Endoscopy Group, Inc., Spectrum Surgical Instruments Corp, Total Repair Express, and the remaining interest in VTS Medical Systems, LLC, as described in Note 4 to our consolidated financial statements titled, "Business Acquisitions". The decrease associated with Life Science segment resulted from foreign currency fluctuations. The fiscal 2012 increase in goodwill associated with the Healthcare segment resulted from the acquisition of a privately held company with operations located near Sao Paulo, Brazil which designs and manufactures small, medium, and large sterilizers used by public hospitals, clinics, dental offices and industrial companies (e.g., research laboratories and pharmaceutical research and production companies). The fiscal 2012 increase in goodwill associated with the Isomedix segment resulted from the acquisition of a privately held company with lab operations in Minneapolis, Minnesota which provides validation services to our Customers and is a natural extension of our Isomedix segment. Information regarding our intangible assets is as follows:
Certain trademarks and tradenames acquired in fiscal 2013 are indefinite-lived assets. Total amortization expense for finite-lived intangible assets was $13,068, $7,726, and $6,617 for the years ended March 31, 2013, 2012, and 2011, respectively. Based upon the current amount of intangible assets subject to amortization, the amortization expense for each of the five succeeding fiscal years is estimated to be as follows:
The estimated annual amortization expense presented in the preceding table has been calculated based upon March 31, 2013 foreign currency exchange rates. |

| Business Acquisition [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Business Combination Disclosure [Text Block] | BUSINESS ACQUISTIONS United States Endoscopy Group, Inc. In August 2012, we completed the acquisition of all the outstanding shares of capital stock of United States Endoscopy Group, Inc. (“US Endoscopy”). The purchase price was approximately $270,000, plus a working capital adjustment of $2,145, which adjustment was paid during the third quarter of fiscal year 2013. In addition, we purchased all real estate used in the US Endoscopy business for approximately $7,000, including properties owned by two US Endoscopy affiliates. We did not assume any existing debt in connection with the purchases. The purchases were financed by a combination of cash on hand and borrowings under our existing credit facility. US Endoscopy is being integrated into the Healthcare segment. We recorded acquisition related costs of $4,006, before tax, which are reported in selling, general and administrative expenses. We anticipate that the acquisition will qualify for a joint election tax benefit under Section 338(h)(10) of the Internal Revenue Code, which allows goodwill and intangibles to be fully deductible for tax purposes. The intangible assets acquired consist of trademarks, trade names and developed technologies, which will be amortized on a straight line basis over thirteen to fifteen years, with the exception of the US Endoscopy trade name which has an indefinite life. Spectrum Surgical Instruments Corp and Total Repair Express In October 2012, we purchased two privately-owned businesses: Spectrum Surgical Instruments Corp ("Spectrum") and Total Repair Express ("TRE"), providers of surgical instrument repair services and instrument care products to hospitals and surgery centers in the United States. The aggregate purchase price of approximately $110,000, including contingent consideration, was financed with borrowings under the existing credit facility. The purchase price remains subject to a working capital adjustment as of March 31, 2013. The instrument repair business is being integrated into the Healthcare business segment. We recorded acquisition related costs of $2,283, before tax, which are reported in selling, general and administrative expenses. We anticipate that the acquisition of Spectrum will qualify for a joint election tax benefit under Section 338(h)(10) of the Internal Revenue Code, which allows goodwill and intangibles to be fully deductible for tax purposes. The intangible assets acquired consist of trademarks, customer relationships and non-compete arrangements, which will be amortized on a straight line basis over one to fifteen years with the exception of the Spectrum tradename which has an indefinite life. VTS Medical Systems, LLC In December 2012, we purchased the remaining interests in our VTS Medical Systems, LLC ("VTS") joint venture. The joint venture began in fiscal 2009, and we increased our ownership of the joint venture to just under 50% during fiscal 2011. The fair value of our equity interest held in VTS immediately before the date of acquisition was $22,034, which approximated fair value. With this final investment, VTS is now a wholly-owned subsidiary of STERIS and is being integrated into the Healthcare business segment. We purchased the remaining interests for a total of approximately $19,000, comprised of cash at closing and deferred cash payments to be paid over a ten year period. We recorded acquisition related costs of $27, before tax, which are reported in selling, general and administrative expenses. We consolidated VTS for the first time in the third quarter of fiscal 2013. The Consolidated Financial Statements include the operating results of USE, Spectrum, TRE and VTS from the date of acquisitions. Pro-forma results of operations for fiscal 2013 and 2012 periods have not been presented because the effects of the acquisition were not material to our financial results. The table below summarizes the allocation of the purchase price to the net assets acquired based on fair values at the acquisition dates for our fiscal 2013 acquisitions. For VTS, the table below includes the net assets included in the consolidated balance sheet including the allocation of the purchase price, based on estimated fair values at the closing date.
(1) Purchase price allocation is still preliminary as of March 31, 2013, as valuations of intangible assets acquired have not been finalized. |

| Debt | DEBT Indebtedness was as follows:
In February 2013, we issued $100,000 of senior notes in a private placement to certain institutional investors in an offering that was exempt from the registration requirements of the Securities Act of 1933. Of the $100,000 of notes, $47,500 have a maturity of nine years and 10 months at an annual interest rate of 3.20%, an additional $40,000 have a maturity of 11 years and 10 months at an annual interest rate of 3.35%, and the remaining $12,500 have a maturity of 14 years and 10 months at an annual interest rate of 3.55%. These borrowings were used primarily for the repayment of existing credit facility debt. The agreements governing these notes contain a financial covenant, including limitations on debt. In December 2012, we issued $100,000 in senior notes in a private placement to certain institutional investors in an offering that was exempt from the registration requirements of the Securities Act of 1933. Of the $100,000 of notes, $47,500 have a maturity of 10 years at an annual interest rate of 3.20%, an additional $40,000 have a maturity of 12 years at an annual interest rate of 3.35%, and the remaining $12,500 have a maturity of 15 years at an annual interest rate of 3.55%. These borrowings were used primarily for the repayment of existing credit facility debt. The agreements governing these notes contain a financial covenant, including limitations on debt. On August 15, 2008, we issued $150,000 of senior notes in a private placement to certain institutional investors in an offering that was exempt from the registration requirements of the Securities Act of 1933. We have used and will use the proceeds for general corporate purposes, including repayment of debt, capital expenditures, acquisitions, dividends, and share repurchases. Of the $150,000 in senior notes, $30,000 have a maturity of five years at an annual interest rate of 5.63%, another $85,000 have a maturity of 10 years at an annual interest rate of 6.33%, and the remaining $35,000 have a maturity of 12 years at an annual interest rate of 6.43%. The agreements governing these notes contain financial covenants, including limitations on debt and a minimum consolidated net worth requirement. In December 2003, we issued $100,000 of senior notes, of which $60,000 currently remain outstanding, in a private placement to certain institutional investors in an offering that was exempt from the registration requirements of the Securities Act of 1933. Of the outstanding notes, $40,000 have a maturity of 10 years at an annual interest rate of 5.25%, and the remaining $20,000 have a maturity of 12 years at an annual interest rate of 5.38%. The agreements governing these notes contain financial covenants, including limitations on debt and a minimum consolidated net worth requirement. On April 13, 2012 we signed a Third Amended and Restated Credit Agreement (the "Credit Agreement") with KeyBank National Association, as administrative agent (“Agent”) for the lenders from time to time party thereto ("Lenders") and such Lenders. The Credit Agreement amended, restated and replaced our previous credit agreement. The Credit Agreement initially provided a $300,000 credit facility, and was amended in October 2012 to increase the credit facility to $400,000 (which may be increased by up to an additional $100,000 in specified circumstances, and subject to certain Lender consent requirements) for borrowings and letters of credit, and will mature April 13, 2017. The aggregate unpaid principal amount of all borrowings, to the extent not previously repaid, is repayable on that date. Borrowings also are repayable at such other earlier times as may be required under or permitted by the terms of the Credit Agreement. Borrowings bear interest at floating rates based upon the Base Rate (as defined) or fixed rates based upon the Eurodollar Rate or Alternate Currency Rate (as defined), plus the Applicable Margin (as defined) in effect from time to time under the Credit Agreement based upon the Company's Leverage Ratio (as defined). Interest on floating rate loans is payable quarterly in arrears and interest on fixed rate loans is payable at the end of the relevant interest period therefor, but in no event less frequently than every three months. The Credit Agreement also requires the payment of a facility fee on the total facility commitment amount, which fee is determined based on the Company's Leverage Ratio. There is no premium or penalty for prepayment of floating rate loans but prepayments of fixed rate loans may be subject to a prepayment fee. The Credit Agreement also permits the Company to make short term "Swing Loan" borrowings from the Agent in an aggregate amount not to exceed $35,000 outstanding at any time. Swing Loans bear interest at the Agent's cost of funds plus the applicable margin in effect from time to time. The Credit Agreement requires the Company to maintain compliance with certain financial covenants, including a maximum Leverage Ratio and a minimum Interest Coverage Ratio. The Company's obligations under the Credit Agreement are unsecured but guaranteed by its material domestic subsidiaries. As of March 31, 2013, $82,290 of indebtedness was outstanding under the Credit Agreement. At March 31, 2013, we were in compliance with all financial covenants associated with our indebtedness. The combined annual aggregate amount of maturities of our outstanding debt by fiscal year is as follows:

| Income Tax Expense (Benefit) | NCOME TAXES Income from continuing operations before income taxes was as follows:
The components of the provision for income taxes related to income from continuing operations consisted of the following:
The total provision for income taxes can be reconciled to the tax computed at the United States federal statutory tax rate as follows:
Unrecognized Tax Benefits. We classify uncertain tax positions and related interest and penalties as long-term liabilities within “Other liabilities” in our accompanying Consolidated Balance Sheets, unless they are expected to be paid within 12 months, in which case, the uncertain tax positions would be classified as current liabilities within “Accrued income taxes.” We recognize interest and penalties related to unrecognized tax benefits within “Income tax expense” in our accompanying Consolidated Statements of Income. A reconciliation of the beginning and ending balances of the total amounts of unrecognized tax benefits is as follows:
The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate is $9,362 at March 31, 2013 and $1,242 at March 31, 2012. In addition, we believe that it is reasonably possible that unrecognized tax benefits may decrease by up to $9,355 within 12 months of March 31, 2013, primarily as a result of audit settlements and the lapse of statute of limitations. For the years ended March 31, 2013 and 2012, current income tax expense includes (benefit) expense of $(659) and $(631) for interest, and (benefit) expense of $(33) and $(16) for penalties, respectively. In total, as of March 31, 2013 and 2012, we have recognized a liability for interest of $276 and $936 and penalties of $31 and $64, respectively. We operate in numerous taxing jurisdictions and are subject to regular examinations by various United States federal, state and local, as well as foreign jurisdictions. We are no longer subject to United States federal examinations for years before fiscal 2012 and, with limited exceptions, we are no longer subject to United States state and local, or non-United States, income tax examinations by tax authorities for years before fiscal 2008. We remain subject to tax authority audits in various jurisdictions wherever we do business. We do not expect the results of these examinations to have a material adverse affect on our consolidated financial statements. Deferred Taxes. The significant components of the deferred tax assets and liabilities recorded in our accompanying balance sheets at March 31, 2013 and 2012 were as follows:
At March 31, 2013, we had federal operating loss carryforwards of $1,449, which can be utilized subject to certain limitations, and foreign operating loss carry forwards of $50,469. Substantially all of the foreign carryforwards have a definite expiration period and will expire if unused between fiscal years 2014 and 2020. In addition, we have recorded tax benefits of $964 related to state operating loss carryforwards. At March 31, 2013, we had $75 of tax credit carryforwards. These credit carryforwards expire between fiscal 2017 and fiscal 2026. We review the need for a valuation allowance against our deferred tax assets. A valuation allowance of $12,428 has been applied to a portion of the net deferred tax assets because we do not believe it is more-likely-than-not that we will receive future benefit. The valuation allowance increased during fiscal 2013 by $586. At March 31, 2013, cumulative undistributed earnings of international operations amounted to approximately $207,800. These earnings are indefinitely reinvested in international operations. Accordingly, no provision has been made for deferred taxes related to the future repatriation of such earnings, nor is it practicable to determine the amount of this liability. At March 31, 2013, we had a current prepaid income tax position. This was mainly due to the timing of U.S. Federal income tax estimated payments and a prior year overpayment carryforward. |

| Benefit Plans | BENEFIT PLANS We provide defined benefit pension plans for certain former manufacturing and plant administrative personnel throughout the world as determined by collective bargaining agreements or employee benefit standards set at the time of acquisition of certain businesses. In addition to providing pension benefits to certain employees, we sponsor an unfunded post-retirement welfare benefits plan for two groups of United States retirees; including the same retirees who receive pension benefits under the United States defined benefit pension plan. Benefits under this plan include retiree life insurance and retiree medical insurance, including prescription drug coverage. During the second quarter of fiscal 2009, we amended our United States post-retirement welfare benefits plan, reducing the benefits to be provided to retirees under the plan and increasing their share of the costs. The amendments resulted in a decrease of $46,001 in the accumulated post-retirement benefit obligation. The impact of this change was recognized in our Consolidated Balance Sheets in fiscal 2009 and is being amortized as a component of the annual net periodic benefit cost over a period of approximately thirteen years. A defined benefit pension plan is also provided to the employees of our former Pieterlen, Switzerland manufacturing facility. Restructuring actions related to the Pieterlen, Switzerland manufacturing facility were taken as part of the Fiscal 2010 Restructuring Plan. These actions resulted in workforce reductions that resulted in curtailments and complete settlement of the plan as the vested benefits of affected employees were substantially settled. We recognize the funded status of our defined benefit pension and post-retirement benefit plans in our Consolidated Balance Sheets, with a corresponding adjustment to accumulated other comprehensive income, net of tax. The funded status is measured as of March 31 each year and is calculated as the difference between the fair value of plan assets and the benefit obligation (which is the projected benefit obligation for pension plans and the accumulated post-retirement benefit obligation for post-retirement benefit plans). Accumulated comprehensive income (loss) represents the net unrecognized actuarial losses and unrecognized prior service cost. These amounts will be recognized in net periodic benefit cost as they are amortized. We will recognize future changes to the funded status of these plans in the year the change occurs, through other comprehensive income. Obligations and Funded Status. The following table reconciles the funded status of the defined benefit pension plans and the other post-retirement medical benefit plan to the amounts recorded on our Consolidated Balance Sheets at March 31, 2013 and 2012, respectively. Benefit obligation balances presented in the following table reflect the projected benefit obligations for our defined benefit pension plans and the accumulated other post-retirement benefit obligation for our post-retirement medical benefit plan. The measurement date of our defined benefit pension plans and other post-retirement medical benefit plan is March 31, for both periods presented.
Amounts recognized in the consolidated balance sheets consist of the following:
The pre-tax amount of unrecognized actuarial net loss and unamortized prior service cost included in accumulated other comprehensive (loss) income at March 31, 2013 was $(38,141) and $29,632, respectively. During fiscal 2014, we will amortize the following pre-tax amounts from accumulated other comprehensive income:
Defined benefit plans with an accumulated benefit obligation exceeding the fair value of plan assets had the following plan assets and obligations at March 31, 2013 and 2012:
Defined benefit plans with a projected benefit obligation exceeding the fair value of plan assets had the following plan assets and obligations at March 31, 2013 and 2012:
Components of Net Periodic Benefit Cost and Other Amounts Recognized in Other Comprehensive Income. Components of the annual net periodic benefit cost of our defined benefit pension plans and our other post-retirement medical benefit plan were as follows:
Assumptions Used in Calculating Benefit Obligations and Net Periodic Benefit Cost. The following table presents significant assumptions used to determine the projected benefit obligations at March 31:
The following table presents significant assumptions used to determine the net periodic benefit costs for the years ended March 31:
The net periodic benefit cost and the actuarial present value of projected benefit obligations are based upon assumptions that we review on an annual basis. These assumptions may be revised annually based upon an evaluation of long-term trends, as well as market conditions that may have an impact on the cost of providing benefits. We develop our expected long-term rate of return on plan assets assumptions by evaluating input from third-party professional advisors, taking into consideration the asset allocation of the portfolios and the long-term asset class return expectations. We develop our discount rate assumptions by evaluating input from third-party professional advisors, taking into consideration the current yield on country specific investment grade long-term bonds which provide for similar cash flow streams as our projected obligations. We have made assumptions regarding healthcare costs in computing our other post-retirement benefit obligation. The assumed rates of increase generally decline ratably over a five-year period from the assumed current year healthcare cost trend rate to the assumed long-term healthcare cost trend rate noted below.
To determine the healthcare cost trend rates, we evaluate a combination of information, including ongoing claims cost monitoring, annual statistical analyses of claims data, reconciliation of forecasted claims against actual claims, review of trend assumptions of other plan sponsors and national health trends, and adjustments for plan design changes, workforce changes, and changes in plan participant behavior. A one-percentage-point change in assumed healthcare cost trend rates (including medical, prescription drug, and long-term rates) would have had the following effect at March 31, 2013:
Plan Assets. Our United States and Switzerland defined benefit pension plans are funded. The following table presents the targeted asset allocation of plan assets at March 31, 2013 and the actual allocation of plan assets at March 31, 2013 and 2012 for these plans:
The long-term target allocations in the preceding table reflect our asset class return expectations and tolerance for investment risk within the context of the pension plans’ long-term benefit obligations. Investment policies, strategies, and long-term target allocations are developed on a plan specific and country specific basis. We continually challenge the long-term target asset allocations and support the allocations by an analysis that incorporates historical and expected returns by asset class as well as volatilities across asset classes and our liability profile. Due to market conditions and other factors, actual asset allocations may vary from the long-term target allocations presented in the preceding table. Plan assets for our U.S. defined benefit plan are managed by outside investment managers pursuant to investment policy guidelines established by the Company for the plan. If asset allocations move outside of the target ranges, the portfolios are rebalanced. For the purpose of the above analysis, debt and equity securities include fixed income and equity security mutual funds, respectively. At March 31, 2013 and 2012, the plans’ assets did not include investments in STERIS common shares. Financial instruments included in pension plan assets are categorized into three tiers. These tiers include a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology as follows: Level 1 - Quoted prices for identical assets in active markets. Level 2 - Quoted prices for similar assets in active markets with inputs that are observable, either directly or indirectly. Level 3 - Unobservable prices or inputs in which little or no market data exists. The fair value of our pension benefits plan assets at March 31, 2013 and 2012 by asset category is as follows:
Cash Flows. We contribute amounts to our defined benefit pension plans at least equal to the minimum amounts required by applicable employee benefit laws and local tax laws. We have recorded liabilities for amounts greater than the required funding levels on our accompanying Consolidated Balance Sheets. As of March 31, 2013, we do not expect to make additional contributions to the U.S. qualified defined benefit pension plan in fiscal 2014. Based upon the actuarial assumptions utilized to develop our benefit obligations at March 31, 2013, the following benefit payments are expected to be made to plan participants:
The Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Act”) provides a prescription drug benefit for Medicare beneficiaries, a benefit we provide to Medicare eligible retirees covered by our post-retirement benefits plan. We have concluded that the prescription drug benefit provided in our post-retirement benefit plan is considered to be actuarially equivalent to the benefit provided under the Act and thus qualifies for the subsidy under the Act. Benefits are subject to a per capita per month cost cap and any costs above the cap become the responsibility of the retiree. The subsidy is applied to reduce the retiree responsibility. As a result, the expected future subsidy no longer reduces our accumulated post-retirement benefit obligation and net periodic benefit cost. We collected subsidies totaling approximately $400 and $420, during fiscal 2013 and fiscal 2012, respectively, which reduced the retiree responsibility for costs in excess of the caps established in the post-retirement benefit plan. Defined Contribution Plans. We maintain a 401(k) defined contribution plan for eligible United States employees and a similar savings plan for Canadian employees. We provide a match on a specified portion of an employee’s contribution. The United States plan assets are held in trust and invested as directed by the plan participants. The Canadian plan assets are held by insurance companies. The aggregate fair value of plan assets was $362,850 at March 31, 2013. At March 31, 2013, the plan held 780,044 STERIS common shares with a fair value of $32,458. We paid dividends of $592, $545, and $498 to the plan and participants on STERIS common stock held by the plan for the years ended March 31, 2013, 2012, and 2011, respectively. We contributed $7,974, $7,771, and $7,990, to the defined contribution plan for the years ended March 31, 2013, 2012, and 2011, respectively. We also maintain a domestic non-qualified deferred compensation plan covering certain employees, which formerly allowed for the deferral of compensation for an employee-specified term or until retirement or termination. Employee contributions to this plan were $443 and $237 in fiscal 2012, and fiscal 2011, respectively. The Plan was amended in fiscal 2012 to disallow deferrals of salary payable in 2012 and subsequent calendar years and of commissions and other incentive compensation payable in respect of the 2013 and subsequent fiscal years. We hold investments in mutual funds to satisfy future obligations of the plan. We account for these assets as available-for-sale securities and they are included in “Other assets” on our accompanying Consolidated Balance Sheets, with a corresponding liability for the plan’s obligation recorded in “Accrued expenses and other.” The aggregate value of the assets was $3,139 and $3,032 at March 31, 2013 and March 31, 2012, respectively. Realized gains and losses on these investments are recorded in “Interest and miscellaneous income” within “Non-operating expenses” on our accompanying Consolidated Statements of Income. Changes in the fair value of the assets are recorded in other comprehensive income on our accompanying balance sheets. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Schedule of Loss Contingencies by Contingency [Text Block] | COMMITMENTS AND CONTINGENCIES We are, and will likely continue to be, involved in a number of legal proceedings, government investigations, and claims, which we believe generally arise in the course of our business, given our size, history, complexity, and the nature of our business, products, Customers, regulatory environment, and industries in which we participate. These legal proceedings, investigations and claims generally involve a variety of legal theories and allegations, including, without limitation, personal injury (e.g., slip and falls, burns, vehicle accidents), product liability or regulation (e.g., based on product operation or claimed malfunction, failure to warn, failure to meet specification, or failure to comply with regulatory requirements), product exposure (e.g., claimed exposure to chemicals, asbestos, contaminants, radiation), property damage (e.g., claimed damage due to leaking equipment, fire, vehicles, chemicals), commercial claims (e.g., breach of contract, economic loss, warranty, misrepresentation), financial (e.g., taxes, reporting), employment (e.g., wrongful termination, discrimination, benefits matters), and other claims for damage and relief. We believe we have adequately reserved for our current litigation and claims that are probable and estimable, and further believe that the ultimate outcome of these pending lawsuits and claims will not have a material adverse affect on our consolidated financial position or results of operations taken as a whole. Due to their inherent uncertainty, however, there can be no assurance of the ultimate outcome or effect of current or future litigation, investigations, claims or other proceedings (including without limitation the matters discussed below). For certain types of claims, we presently maintain insurance coverage for personal injury and property damage and other liability coverages in amounts and with deductibles that we believe are prudent, but there can be no assurance that these coverages will be applicable or adequate to cover adverse outcomes of claims or legal proceedings against us. As previously disclosed, we received a warning letter (the “warning letter”) from the FDA on May 16, 2008 regarding our SYSTEM 1® sterile processor and the STERIS 20 sterilant used with the processor (sometimes referred to collectively in the FDA letter and in this note 11 as the “device”). Among other matters, the warning letter included the FDA's assertion that significant changes or modifications had been made in the design, components, method of manufacture, or intended use of the device beyond the FDA's 1988 clearance, such that the FDA believed a new premarket notification submission (known within FDA regulations as a 510(k) submission) should have been made, and the assertion that our failure to make such a submission resulted in violations of applicable law. After ongoing discussions with the FDA, in April 2010 we reached agreement with the FDA on the terms of a consent decree (“Consent Decree”). On April 19, 2010, a Complaint and Consent Decree were filed in the U.S. District Court for the Northern District of Ohio, and on April 20, 2010, the Court approved the Consent Decree. In general, the Consent Decree addresses regulatory matters regarding SYSTEM 1, restricts further sales of SYSTEM 1 processors in the U.S., defines certain documentation and other requirements for continued service and support of SYSTEM 1 in the U.S., prohibits the sale of liquid chemical sterilization or disinfection products in the U.S. that do not have FDA clearance, describes various process and compliance matters, and defines penalties in the event of violation of the Consent Decree. The Consent Decree also provided the terms under which we temporarily continued to support our Customers' use of SYSTEM 1 in the U.S., including the sale of consumables, parts and accessories and service for a transition period, (the “Transition Plan”), which included the “SYSTEM 1 Rebate Program” (the “Rebate Program”). In April 2010, we began to offer rebates in the form of cash or future purchase credits to U.S. Customers that purchased SYSTEM 1 processors directly from us or who were users of SYSTEM 1 at the time the Rebate Program was introduced and who returned their units. In addition, we provided credits for the return of SYSTEM 1 consumables in unbroken packaging and within shelf life and for the unused portion of SYSTEM 1 service contracts. The Rebate Program ended August 2, 2012. Customers utilized rebates totaling approximately $66,600 on orders placed since the initiation of the Rebate Program. The costs associated with the Rebate Program were lower than originally estimated because fewer Customers elected to participate in the Rebate Program than anticipated. The remaining recorded accrual is $210 as of March 31, 2013. The Consent Decree has defined the resolution of a number of issues regarding SYSTEM 1, and we believe our actions with respect to SYSTEM 1, including the Transition Plan, were and are not recalls, corrections or removals under FDA regulations. However, there is no assurance that these or other claims will not be brought or that judicial, regulatory, administrative or other legal or enforcement actions, notices or remedies will not be pursued, or that action will not be taken in respect of the Consent Decree, the Transition Plan, SYSTEM 1, or otherwise with respect to regulatory or compliance matters, as described in this note 11 and in various portions of Item 1A. of Part I of this Annual Report on Form 10-K for the year ended March 31, 2013. On February 5, 2010, a complaint was filed by a Customer that claimed to have purchased two SYSTEM 1 devices from STERIS, Physicians of Winter Haven LLC d/b/a Day Surgery Center v. STERIS Corp., Case No. 1:1-cv-00264-CAB (N.D. Ohio). The complaint alleged statutory violations, breaches of various warranties, negligence, failure to warn, and unjust enrichment and Plaintiff sought class certification, damages, and other legal and equitable relief including, without limitation, attorneys' fees and an order requiring STERIS to replace, recall or adequately repair the product and/or to take appropriate regulatory action. On February 7, 2011 we entered into a settlement agreement in which we agreed, among other things, to provide various categories of economic relief for members of the settlement class and not object to plaintiff's counsel's application to the court for attorneys' fees and expenses up to a specified amount. Certification of a settlement class was approved and final approval of the settlement was given by the court in the first quarter of fiscal 2012. During the third quarter of fiscal 2011, we recorded in operating expenses a pre-tax charge of approximately $19,796 related to the settlement of these proceedings. The assumptions regarding the amount of this charge included, among others, the portion of class members participating in the settlement and their choice of the categories of economic relief available for such members. The claim submission deadline was December 31, 2012. As a result during fiscal 2013, we adjusted the liability related to the SYSTEM 1 class action settlement. The pretax adjustments amounted to $16,782, and were recorded as reductions to operating expenses. The remaining recorded accrual is $43 as of March 31, 2013 and is based on actual claims submitted through March 31, 2013. On May 31, 2012, our Albert Browne Limited subsidiary received a warning letter from the FDA regarding chemical indicators manufactured in the United Kingdom. These devices are intended for the monitoring of certain sterilization and other processes. The FDA warning letter states that the agency has concerns regarding operational business processes. We do not believe that the FDA's concerns are related to product performance, or that they result from Customer complaints. We have reviewed our processes with the agency and finalized our remediation measures, and are awaiting FDA reinspection. We do not currently believe that the impact of this event will have a material adverse effect on our financial results. Other civil, criminal, regulatory or other proceedings involving our products or services also could possibly result in judgments, settlements or administrative or judicial decrees requiring us, among other actions, to pay damages or fines or effect recalls, or be subject to other governmental, Customer or other third party claims or remedies, which could materially affect our business, performance, prospects, value, financial condition, and results of operations. For additional information regarding these matters, see the following portions in this Annual Report on Form 10-K for the fiscal year ended March 31, 2013: “Business - Information with respect to our Business in General - Government Regulation”, and the “Risk Factor” titled “We may be adversely affected by product liability claims or other legal actions or regulatory or compliance matters, including the Warning Letter and Consent Decree” and the "Risk Factor” titled “Compliance with the Consent Decree may be more costly and burdensome than anticipated.” From time to time, STERIS is also involved in legal proceedings as a plaintiff involving contract, patent protection, and other claims asserted by us. Gains, if any, from these proceedings are recognized when they are realized. We are subject to taxation from United States federal, state and local, and foreign jurisdictions. Tax positions are settled primarily through the completion of audits within each individual jurisdiction or the closing of statutes of limitation. Changes in applicable tax law or other events may also require us to revise past estimates. Changes in applicable tax law or other events may also require us to revise past estimates. We describe income taxes further in Note 9 to our consolidated financial statements titled, “Income Tax Expense” in this Annual Report on Form 10-K. Additional information regarding our contingencies is included in Item 7 of Part II titled, “Management’s Discussion and Analysis of Financial Conditions and Results of Operations,” and in Item 3 of Part I titled, “Legal Proceedings” contained in this Annual Report on Form 10-K. As of March 31, 2013 and 2012, our commercial commitments totaled $45,804 and $38,264, respectively. Commercial commitments include standby letters of credit, letters of credit required as security under our self-insured risk retention policies, and other potential cash outflows resulting from an event that requires payment by us. Approximately $5,961 and $6,261, respectively, of the totals at March 31, 2013 and 2012 relate to letters of credit required as security under our self-insured risk retention policies. As of March 31, 2013 and 2012, we had minimum purchase commitments with suppliers for raw material purchases totaling $59,358 and $27,440, respectively. |

| Business Segment Information | We operate and report in three business segments: Healthcare, Life Sciences, and Isomedix. Corporate and other, which is presented separately, contains the Defense and Industrial business unit plus costs that are associated with being a publicly traded company and certain other corporate costs. Our Healthcare segment manufactures and sells capital equipment, accessory, consumable, and service solutions to healthcare providers, including acute care hospitals, and surgery and gastrointestinal centers. These solutions aid our Customers in improving the safety, quality, and productivity of their surgical, sterile processing, gastrointestinal, and emergency environments. Our Life Sciences segment manufactures and sells engineered capital equipment, formulated cleaning chemistries, and service solutions to pharmaceutical companies, and private and public research facilities around the globe. Our Isomedix segment operates through a network of facilities located in North America. We sell a comprehensive array of materials processing services using gamma irradiation, and ethylene oxide (“EO”) technologies. We provide microbial reduction services based on Customer specifications to companies that supply products to the healthcare, industrial, and consumer products industries. Financial information for each of our segments is presented in the following table. Operating income (loss) for each segment is calculated as the segment’s gross profit less direct expenses and indirect cost allocations, which results in the full allocation of all distribution and research and development expenses, and the partial allocation of corporate costs. These allocations are based upon variables such as segment headcount and revenues. In addition, the Healthcare segment is responsible for the management of all but one manufacturing facility and uses standard cost to sell products to the Life Sciences segment. Corporate and other includes the gross profit and direct expenses of the Defense and Industrial business unit, as well as certain unallocated corporate costs related to being a publicly traded company and legacy pension and post-retirement benefits. The accounting policies for reportable segments are the same as those for the consolidated Company. For the year ended March 31, 2013, revenues from a single Customer did not represent ten percent or more of any reportable segment’s revenues.
(1) Includes an increase of $22,367 in fiscal 2013, an increase of $15,306 in fiscal 2012 and a reduction of $102,313 in fiscal 2011, resulting from the SYSTEM 1 Rebate Program. (2) Includes an increase of $23,640 in fiscal 2013, an increase of $17,403 in fiscal 2012 and a reduction of $110,004 in fiscal 2011, resulting from SYSTEM 1 Rebate Program, and an increase of $16,782 in fiscal year 2013 and a reduction of $19,796 in fiscal 2011, resulting from the class action settlement. For the year ended March 31, 2013, pre-tax restructuring expenses of $(565) are included in the operating results of the Healthcare segment. For the year ended March 31, 2012, pre-tax restructuring expenses of $644 are included in the operating results of the Healthcare segment. For the year ended March 31, 2011, pre-tax restructuring expenses of $1,020, $190 and $142 are included in the operating results of the Healthcare, Life Sciences and Isomedix segments, respectively. Assets include the current and long-lived assets directly attributable to the segment based on the management of the location or on utilization. Certain corporate assets were allocated to the reportable segments based on revenues. Assets attributed to sales and distribution locations are only allocated to the Healthcare and Life Sciences segments. Corporate and other includes assets directly attributable to the Defense and Industrial business unit, as well as certain unallocated amounts related to being a publicly traded company. Total assets associated with the Healthcare segment have increased substantially during fiscal 2013, as a result of several business acquisitions as described in Note 4 to our consolidated financial statements titled, "Business Acquisitions". Individual facilities, equipment, and intellectual properties are utilized for production by both the Healthcare and Life Sciences segments at varying levels over time. As a result, an allocation of total assets, capital expenditures, and depreciation and amortization is not meaningful to the individual performance of the Healthcare and Life Sciences segments. Therefore, their respective amounts are reported together.
Financial information for each of our United States and international geographic areas is presented in the following table. Revenues are based on the location of these operations and their Customers. Property, plant and equipment, net are those assets that are identified within the operations in each geographic area.

| Earnings Per Share [Text Block] | We calculate basic earnings per common share based upon the weighted average number of common shares outstanding. We calculate diluted earnings per share based upon the weighted average number of common shares outstanding plus the dilutive effect of common share equivalents calculated using the treasury stock method. The following is a summary of common shares and common share equivalents outstanding used in the calculations of basic and diluted earnings per share:
Options to purchase the following number of common shares were outstanding but excluded from the computation of diluted earnings per share because the combined exercise prices, unamortized fair values, and assumed tax benefits upon exercise were greater than the average market price for the common shares during the periods, so including these options would be anti-dilutive:

| Schedule of Treasury Stock by Class [Text Block] | REPURCHASES OF COMMON SHARES In March 2008, we announced that the Company’s Board of Directors provided authorization to repurchase up to $300,000 of STERIS common shares. The March 2008 common share repurchase authorization does not have a stated maturity date. Under this authorization, we may purchase shares from time to time through open market purchases, including transactions pursuant to Rule 10b5-1 plans, or privately negotiated transactions. Under the stock repurchase authorization provided by our Board of Directors, we repurchased 204,349 of our common shares during fiscal 2013 in the aggregate amount of $6,830, representing an average price of $33.42 per common share. During fiscal 2012, we paid an aggregate amount of $55,942 for the repurchase of 1,851,510 of our common shares, representing an average price of $30.21 per common share. During fiscal 2011, we paid an aggregate amount of $29,462 for the repurchase of 925,848 of our common shares, representing an average price of $31.82 per common share. We obtained 52,893 of our common shares during fiscal 2013 in the aggregate amount of $1,172 in connection with stock based compensation award programs. We obtained 22,927 of our common shares during fiscal 2012 in the aggregate amount of $808 in connection with these programs. We obtained 15,224 of our common shares during fiscal 2011 in the aggregate amount of $503 in connection with these programs. At March 31, 2013, $111,630 of STERIS common shares remained authorized for repurchase pursuant to the most recent Board approved repurchase authorization (the March 2008 Board Authorization). Also, 11,280,510 common shares were held in treasury at March 31, 2013. |

| Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-Based Compensation | SHARE-BASED COMPENSATION We maintain a long-term incentive plan that makes available common shares for grants, at the discretion of the Compensation Committee of the Board of Directors, to officers, directors, and key employees in the form of stock options, restricted shares, restricted share units, and stock appreciation rights. Stock options provide the right to purchase our common shares at the market price on the date of grant, subject to the terms of the option plans and agreements. Generally, one-fourth of the stock options granted become exercisable for each full year of employment following the grant date. Stock options granted generally expire 10 years after the grant date, or earlier if the option holder is no longer employed by us, unless the option holder has attained age 55 and has at least five years of service upon termination. Restricted shares and restricted share units generally may cliff vest after a three or four year period or vest in tranches of one-fourth of the number granted for each full year of employment after the grant date. As of March 31, 2013, 3,949,453 shares remained available for grant under the long-term incentive plan. The fair value of share-based compensation awards was estimated at their grant date using the Black-Scholes-Merton option pricing model. This model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable, characteristics that are not present in our option grants. If the model permitted consideration of the unique characteristics of employee stock options, the resulting estimate of the fair value of the stock options could be different. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in our Consolidated Statements of Income. The expense is classified as cost of goods sold or selling, general and administrative expenses in a manner consistent with the employee’s compensation and benefits. The following weighted-average assumptions were used for options granted during fiscal 2013, fiscal 2012 and fiscal 2011:
The risk-free interest rate is based upon the U.S. Treasury yield curve. The expected life of options is reflective of historical experience, vesting schedules and contractual terms. The expected dividend yield of stock represents our best estimate of the expected future dividend yield. The expected volatility of stock is derived by referring to our historical stock prices over a time frame similar to that of the expected life of the grant. An estimated forfeiture rate of 1.83%, 2.08% and 2.27% was applied in fiscal 2013, 2012 and 2011, respectively. This rate is calculated based upon historical activity and represents an estimate of the granted options not expected to vest. If actual forfeitures differ from this calculated rate, we may be required to make additional adjustments to compensation expense in future periods. The assumptions used above are reviewed at the time of each significant option grant, or at least annually. A summary of share option activity is as follows:
We estimate that 728,201 of the non-vested stock options outstanding at March 31, 2013 will ultimately vest. The aggregate intrinsic value in the table above represents the total pre-tax difference between the $41.61 closing price of our common shares on March 31, 2013 over the exercise prices of the stock options, multiplied by the number of options outstanding or outstanding and exercisable, as applicable. The aggregate intrinsic value is not recorded for financial accounting purposes and the value changes daily based on the daily changes in the fair market value of our common shares. The total intrinsic value of stock options exercised during the years ended March 31, 2013, 2012 and 2011 was $10,071, $2,846 and $6,669, respectively. Net cash proceeds from the exercise of stock options were $23,019, $5,723 and $12,730 for the years ended March 31, 2013, 2012 and 2011, respectively. The tax benefit from stock option exercises was $2,058, $1,514 and $2,525 for the years ended March 31, 2013, 2012 and 2011, respectively. The weighted average grant date fair value of stock option grants was $7.32, $9.31 and $8.80 for the years ended March 31, 2013, 2012 and 2011, respectively. Stock appreciation rights (“SARS”) carry generally the same terms and vesting requirements as stock options except that they are settled in cash upon exercise and the employee is not required to make payment to exercise and therefore, are classified as liabilities. The fair value of the outstanding SARS as of March 31, 2013 and 2012 was $1,253 and $854, respectively. The fair value of outstanding SARs is revalued at each reporting date and the related liability and expense are adjusted appropriately. A summary of the non-vested restricted share activity is presented below:
Restricted shares granted are valued based on the closing stock price at the grant date. The value of restricted shares that vested during fiscal 2013 was $3,167. Cash settled restricted share units carry generally the same terms and vesting requirements as stock settled restricted share units except that they are settled in cash upon vesting and therefore, are classified as liabilities. The fair value of outstanding cash-settled restricted share units as of March 31, 2013 and 2012 was $1,405 and $1,313, respectively. The fair value of each cash-settled restricted share unit is revalued at each reporting date and the related liability and expense are adjusted appropriately. As of March 31, 2013, there was a total of $15,816 in unrecognized compensation cost related to non-vested share-based compensation granted under our share-based compensation plans. We expect to recognize the cost over a weighted average period of 2.49 years. |

| Product Warranty Disclosure [Text Block] | FINANCIAL AND OTHER GUARANTEES We generally offer a limited parts and labor warranty on capital equipment. The specific terms and conditions of those warranties vary depending on the product sold and the countries where we conduct business. We record a liability for the estimated cost of product warranties at the time product revenues are recognized. The amounts we expect to incur on behalf of our Customers for the future estimated cost of these warranties are recorded as a current liability on the accompanying Consolidated Balance Sheets. Factors that affect the amount of our warranty liability include the number and type of installed units, historical and anticipated rates of product failures, and material and service costs per claim. We periodically assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary. Changes in our warranty liability during the periods presented are as follows:
We also sell product maintenance contracts to our Customers. These contracts range in terms from one to five years and require us to maintain and repair the product over the maintenance contract term. We initially record amounts due from Customers under these contracts as a liability for deferred service contract revenue on the accompanying Consolidated Balance Sheets within “Accrued expenses and other.” The liability recorded for such deferred service revenue was $35,258, $43,252 and $28,230 as of March 31, 2013, March 31, 2012 and March 31, 2011, respectively. Such deferred revenue is then amortized on a straight-line basis over the contract term and recognized as service revenue on our accompanying Consolidated Statements of Income. The activity related to the liability for deferred service contract revenues is excluded from the table presented above. |

| Derivative Instruments and Hedging Activities Disclosure [Text Block] | FORWARD AND SWAP CONTRACTS From time to time, we enter into forward contracts to hedge potential foreign currency gains and losses that arise from transactions denominated in foreign currencies, including inter-company transactions. We also enter into commodity swap contracts to hedge price changes in a certain commodity that impacts raw materials included in our cost of revenues. We do not use derivative financial instruments for speculative purposes. These contracts are not designated as hedging instruments and do not receive hedge accounting treatment; therefore, changes in their fair value are not deferred but are recognized immediately in the Consolidated Statements of Income. At March 31, 2013, we held foreign currency forward contracts to buy 79.7 million Mexican pesos and 12.5 million Canadian dollars. At March 31, 2013, we held commodity swap contracts to buy 103 thousand pounds of nickel.

| Fair Value Disclosures [Text Block] | FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. We estimate the fair value of financial assets and liabilities using available market information and generally accepted valuation methodologies. The inputs used to measure fair value are classified into three tiers. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring the entity to develop its own assumptions. The following table shows the fair value of our financial assets and liabilities at March 31, 2013 and March 31, 2012:
(1) Money market fund holdings are classified as level two as active market quoted prices are not available. (2) The fair values of forward and swap contracts are based on period-end forward rates and reflect the value of the amount that we would pay or receive for the contracts involving the same notional amounts and maturity dates. (3) We maintain a domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of compensation for an employee-specified term or until retirement or termination. Amounts deferred can be allocated to various hypothetical investment options (compensation deferrals have been frozen under the plan). We hold investments to satisfy the future obligations of the plan. Changes in the value of the investment accounts are recognized each period based on the fair value of the underlying investments. Employees making deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)). (4) We estimate the fair value of our long-term debt using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. (5) Contingent consideration obligations arise from prior business acquisitions. The fair values are based on discounted cash flow analyses reflecting the possible achievement of specified performance measures or events and captures the contractual nature of the contingencies, commercial risk, and the time value of money. Contingent consideration obligations are classified in the consolidated balance sheets as accrued expense (short-term) and other liabilities (long-term), as appropriate based on the contractual payment dates. The changes in Level 3 assets and liabilities measured at fair value on a recurring basis at March 31, 2013 are summarized as follows:

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates, Policy | Use of Estimates. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and related notes to financial statements. Actual results could differ from those estimates. On an ongoing basis, we revise the estimates and assumptions as new information becomes available. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents, Policy | Cash Equivalents and Supplemental Cash Flow Information. Cash equivalents are all highly liquid investments with a maturity of three months or less when purchased. We invest our excess cash in short-term instruments including money market funds and time deposits with major banks and financial institutions. We select investments in accordance with the criteria established in our investment policy. Our investment policy specifies, among other things, maturity, credit quality and concentration restrictions with the objective of preserving capital and maintaining adequate liquidity. Information supplementing our Consolidated Statements of Cash Flows is as follows:

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition, Policy | Revenue Recognition. We recognize revenue for products when ownership passes to the Customer, which is based on contract or shipping terms and for services when the service is provided to the Customer. Our Customers include end users as well as dealers and distributors who market and sell our products. Our revenue is not contingent upon resale by the dealer or distributor. We have no further obligations related to bringing about resale and our standard return and restocking fee policies are applied. Revenues are reported net of sales and value-added taxes collected from Customers. We also have individual Customer contracts that offer discounted pricing. Dealers and distributors may be offered sales incentives in the form of rebates. We reduce revenue for discounts and estimated returns, rebates, and other similar allowances in the same period the related revenues are recorded. Returns, rebates, and similar allowances are estimated based on historical experience and trend analysis. In transactions that contain multiple elements, such as when products, maintenance services, and other services are combined, we recognize revenue as each product is delivered or service is provided to the Customer. We allocate the total arrangement consideration to each element based on its relative fair value, based on the price for the product or service when it is sold separately. We offer preventative maintenance agreements to our Customers with contract terms of one to five years which require us to maintain and repair our products during this time. Amounts received under these Customer contracts are initially recorded as deferred service revenues and then recognized as service revenues ratably over the contract term. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Trade and Other Accounts Receivable, Policy | Accounts Receivable. Accounts receivable are presented at their face amount, less allowances for sales returns and uncollectible accounts. Accounts receivable consist of amounts billed and currently due from Customers and amounts earned but unbilled. We generally obtain and perfect security interest in products sold in the United States when we have a concern with the Customer's risk profile. We maintain an allowance for uncollectible accounts receivable for estimated losses in the collection of amounts owed by Customers. We estimate the allowance based on analyzing a number of factors, including amounts written off historically, Customer payment practices, and general economic conditions. We also analyze significant Customer accounts on a regular basis and record a specific allowance when we become aware of a specific Customer’s inability to pay. As a result, the related accounts receivable are reduced to an amount that we reasonably believe is collectible. We maintain an allowance for sales returns based upon known returns and estimated returns for both capital equipment and consumables. We estimate returns of capital equipment and consumables based upon recent historical experience less the estimated inventory value of the returned goods. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventory, Policy | Inventories, net. Inventories are stated at the lower of their cost or market value. We determine cost based upon a combination of the last-in, first-out (“LIFO”) and first-in, first-out (“FIFO”) cost methods. For inventories valued using the LIFO method, we believe that the use of the LIFO method results in a matching of current costs and revenues. Inventories valued using the LIFO method represented approximately 38.6% and 37.7% of total inventories at March 31, 2013 and 2012, respectively. Inventory costs include material, labor, and overhead. If we had used only the FIFO method of inventory costing, inventories would have been $18,944 and $18,158 higher than those reported at March 31, 2013 and 2012, respectively. We review the net realizable value of inventory on an ongoing basis, considering factors such as deterioration, obsolescence, and other items. We record an allowance for estimated losses when the facts and circumstances indicate that particular inventories will not be usable. If future market conditions vary from those projected, and our estimates prove to be inaccurate, we may be required to write-down inventory values and record an adjustment to cost of revenues. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property, Plant and Equipment, Policy | Property, Plant, and Equipment. Our property, plant, and equipment consists of land and land improvements, buildings and leasehold improvements, machinery and equipment, information systems, radioisotope (cobalt-60), and construction in progress. Property, plant, and equipment are presented at cost less accumulated depreciation and depletion. We capitalize additions and improvements. Repairs and maintenance are charged to expense as they are incurred. Land is not depreciated and construction in progress is not depreciated until placed in service. Depreciation of most assets is computed on the cost less the estimated salvage value by using the straight-line method over the estimated remaining useful lives. Depletion of radioisotope is computed using the annual decay factor of the material, which is similar to the sum-of-the-years-digits method. We generally depreciate or deplete property, plant, and equipment over the useful lives presented in the following table:
When we sell, retire, or dispose of property, plant, and equipment, we remove the asset’s cost and accumulated depreciation from our Consolidated Balance Sheets. We recognize the net gain or loss on the sale or disposition in the Consolidated Statements of Income in the period when the transaction occurs. Interest. We capitalize interest costs incurred during the construction of long-lived assets. We capitalized interest costs of $585 and $705 for the years ended March 31, 2013 and 2012, respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Goodwill and Intangible Assets, Policy | Identifiable Intangible Assets. Our identifiable intangible assets include product technology rights, trademarks, licenses, and Customer relationships. We record these assets at cost, or when acquired as part of a business acquisition, at estimated fair value. We generally amortize identifiable intangible assets over periods ranging from 5 to 20 years using the straight-line method. Goodwill. We perform our annual impairment test for goodwill in the third quarter of each year. We may consider qualitative indicators of the fair value of a reporting unit when it is unlikely that a reporting unit has impaired goodwill. We may also utilize a discounted cash flow analysis that requires certain assumptions and estimates be made regarding market conditions and our future profitability. In those circumstances we test goodwill for impairment by reviewing the book value compared to the fair value at the reporting unit level. We calculate the fair value of our reporting units based on the present value of estimated future cash flows. Considerable management judgment is necessary to evaluate the impact of operating and macroeconomic changes and to estimate future cash flows to measure fair value. Assumptions used in our impairment evaluations, such as forecasted growth rates and cost of capital, are consistent with internal projections and operating plans. We believe such assumptions and estimates are also comparable to those that would be used by other marketplace participants. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Investment, Policy | Investments. Investments in marketable securities are stated at fair value and are included in "Other assets" on the Consolidated Balance Sheets. Unrealized gains and losses on marketable securities classified as available-for-sale are recorded in Accumulated Other Comprehensive Income (Loss). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Impairment or Disposal of Long-Lived Assets, Policy | Asset Impairment Losses. Property, plant, equipment, and identifiable intangible assets are reviewed for impairment when indicators of impairment exist and circumstances indicate that the carrying value of such assets may not be recoverable. Impaired assets are recorded at the lower of carrying value or estimated fair value. We conduct this review on an ongoing basis and, if an impairment exists, we record the loss in the Consolidated Statements of Income during that period. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Business Combinations Policy | Acquisitions of Business. Assets acquired and liabilities assumed in a business combination are accounted for at fair value on the date of acquisition. Costs related to the acquisition are expensed as incurred. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| SYSTEM 1 Rebate Program | SYSTEM 1 Rebate Program. The Accrued SYSTEM 1 Rebate Program (the “Rebate Program”), initially recognized during the first quarter of fiscal 2011, was based upon the quantity of SYSTEM 1 processors eligible for rebates and the estimated value of rebates to be provided upon their return. The rebate portion of the Rebate Program was recognized as contra-revenue consistent with other returns and allowances offered to Customers. The estimated costs to facilitate the disposal of the returned SYSTEM 1 processors was recognized as cost of revenues. Both components were recorded as current liabilities. The key assumptions involved in the estimates associated with the Rebate Program included: the number and age of SYSTEM 1 processors eligible for rebates under the Rebate Program, the number of Customers that would elect to participate in the Rebate Program, the proportion of Customers that would choose each rebate option, and the estimated per unit costs of disposal. The Rebate Program ended August 2, 2012. Customers utilized rebates totaling approximately $66,600 on orders placed since the initiation of the Rebate Program. The costs associated with the Rebate Program were lower than originally estimated because fewer Customers elected to participate in the Rebate Program than anticipated. The remaining recorded accrual is $210 as of March 31, 2013. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Liability Reserve Estimate, Policy | Self-Insurance Liabilities. We record a liability for self-insured risks that we retain for general and product liabilities, workers’ compensation, and automobile liabilities based on actuarial calculations. We use our historical loss experience and actuarial methods to calculate the liability. This liability includes estimates for both losses and incurred but not reported claims. We review the assumptions used to calculate the estimated liability at least annually to evaluate the adequacy of the amount recorded. We maintain insurance policies to cover losses greater than our estimated liability, which are subject to the terms and conditions of those policies. We are also self-insured for employee medical claims. We estimate a liability for incurred but not reported claims based upon recent claims experience. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Pension and Other Postretirement Plans, Policy | Benefit Plans. We sponsor defined benefit pension and other post-retirement welfare benefit plans for certain former employees. We determine our costs and obligations related to these plans by evaluating input from third-party professional advisors. These costs and obligations are affected by assumptions including the discount rate, expected long-term rate of return on plan assets, the annual rate of change in compensation for eligible employees, estimated changes in costs of healthcare benefits, and other factors. We review the assumptions used on an annual basis. We recognize an asset for the overfunded status or a liability for the underfunded status of defined benefit pension and post-retirement benefit plans in our consolidated balance sheets. This amount is measured as the difference between the fair value of plan assets and the benefit obligation (the projected benefit obligation for pension plans and the accumulated post-retirement benefit obligation for other post-retirement benefit plans). Changes in the funded status of the plans are recorded in other comprehensive income in the year they occur. We measure plan assets and obligations as of the balance sheet date. We provide additional information about our pension and other post-retirement welfare benefits plans in note 10 to our consolidated financial statements titled, “Benefit Plans.” |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value of Financial Instruments, Policy | Fair Value of Financial Instruments. Except for long-term debt, our financial instruments are highly liquid or have short-term maturities. We provide additional information about the fair value of our financial instruments in note 18 titled, “Fair Value Measurements.” |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Foreign Currency Transactions and Translations Policy | Foreign Currency Translation. Most of our operations use their local currency as their functional currency. Financial statements of international subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for revenues, expenses, gains and losses. Translation adjustments for international subsidiaries whose local currency is their functional currency are recorded as a component of accumulated other comprehensive income (loss) within shareholders’ equity. Transaction gains and losses resulting from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency are recognized as incurred in the accompanying Consolidated Statements of Income, except for certain inter-company balances designated as long-term investments. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivatives, Policy | Forward and Swap Contracts. We enter into foreign currency forward contracts to hedge assets and liabilities denominated in foreign currencies, including inter-company transactions. We do not use derivative financial instruments for speculative purposes. These contracts are marked to market, with gains and losses recognized within “Selling, general, and administrative expenses” or "Cost of revenues" in the accompanying Consolidated Statements of Income. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Standard Product Warranty, Policy | Warranty. Warranties are provided on the sale of certain of our products and services and an accrual for estimated future claims is recorded at the time revenue is recognized. We estimate warranty expense based primarily on historical warranty claim experience. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Shipping and Handling Cost, Policy | Shipping and Handling. We record shipping and handling costs in costs of revenues. Shipping and handling costs charged to Customers are recorded as revenues in the period the product revenues are recognized. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Advertising Costs, Policy | Advertising Expenses. Costs incurred for communicating, advertising and promoting our products are generally expensed when incurred as a component of Selling, General and Administrative Expense. We incurred $6,880, $5,857, and $6,013 of advertising costs during the years ended March 31, 2013, 2012, and 2011, respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Research and Development Expense, Policy | Research and Development. We incur research and development costs associated with commercial products and expense these costs as incurred. If a Customer reimburses us for research and development costs, the costs are charged to the related contracts as costs of revenues. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Tax, Policy | Income Taxes. Our income tax expense includes United States federal, state and local, and foreign income taxes, and is based on reported pre-tax income. We defer income taxes for all temporary differences between pre-tax financial and taxable income and between the book and tax basis of assets and liabilities. We record valuation allowances to reduce net deferred tax assets to an amount that we expect will more-likely-than-not be realized. In making such a determination, we consider all available information, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the valuation allowance which would reduce the provision for income taxes and the effective tax rate. We evaluate uncertain tax positions in accordance with a two-step process. The first step is recognition: The determination of whether or not it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, we presume that the position will be examined by the appropriate tax authority and that the tax authority will have full knowledge of all relevant information. The second step is measurement: A tax position that meets the more-likely-than-not threshold is measured to determine the amount of benefit to recognize in the financial statements. The measurement process requires the determination of the range of possible settlement amounts and the probability of achieving each of the possible settlements. The tax position is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. No tax benefits are recognized for positions that do not meet the more-likely-than-not threshold. Tax positions that previously failed to meet the more-likely-than-not threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which the threshold is no longer met. We describe income taxes further in note 9 to our consolidated financial statements titled, “Income Taxes.” |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Medical Device Excise Tax | Medical Device Excise Tax. The Medical Device Excise Tax became effective January 1, 2013. The excise tax was mandated by the 2010 health care reform legislation and assesses a 2.3% tax on the sale or use of certain medical devices that are sold or manufactured in the United States. Many of our products are subject to the excise tax. The tax is included in cost of revenues in the period of sale. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-based Compensation, Option and Incentive Plans Policy | Share-Based Compensation. We describe share-based compensation in note 15 to our consolidated financial statements titled, “Share-Based Compensation.” We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. We record liability awards at fair value each reporting period and the change in fair value is reflected as share-based compensation expense in our Consolidated Statements of Income. The expense is classified as cost of goods sold, selling, general and administrative expenses or research and development expenses in a manner consistent with the employee’s compensation and benefits. These costs are recognized in the Consolidated Statement of Income over the period during which an employee is required to provide service in exchange for the award. Excess tax benefits realized from the exercise of stock options are reported as a financing cash inflow. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Costs Associated with Exit or Disposal Activities or Restructurings, Policy | Restructuring. We have recognized restructuring expenses as incurred. In addition, the property, plant, and equipment associated with the related facilities were assessed for impairment as performed on an annual basis. Asset impairment and accelerated depreciation expenses primarily relate to inventory write-downs for rationalized products and adjustments in the carrying value of the closed facilities to their estimated fair value. In addition, the remaining useful lives of other property, plant, and equipment associated with the related operations were reevaluated based on the respective restructuring plan, resulting in the acceleration of depreciation and amortization of certain assets. |

| Schedule of Business Acquisitions, by Acquisition | We consolidated VTS for the first time in the third quarter of fiscal 2013. The Consolidated Financial Statements include the operating results of USE, Spectrum, TRE and VTS from the date of acquisitions. Pro-forma results of operations for fiscal 2013 and 2012 periods have not been presented because the effects of the acquisition were not material to our financial results. The table below summarizes the allocation of the purchase price to the net assets acquired based on fair values at the acquisition dates for our fiscal 2013 acquisitions. For VTS, the table below includes the net assets included in the consolidated balance sheet including the allocation of the purchase price, based on estimated fair values at the closing date.
(1) Purchase price allocation is still preliminary as of March 31, 2013, as valuations of intangible assets acquired have not been finalized. |

| Fair Value, Measurement Inputs, Disclosure [Table Text Block] | The following table shows the fair value of our financial assets and liabilities at March 31, 2013 and March 31, 2012:
(1) Money market fund holdings are classified as level two as active market quoted prices are not available. (2) The fair values of forward and swap contracts are based on period-end forward rates and reflect the value of the amount that we would pay or receive for the contracts involving the same notional amounts and maturity dates. (3) We maintain a domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of compensation for an employee-specified term or until retirement or termination. Amounts deferred can be allocated to various hypothetical investment options (compensation deferrals have been frozen under the plan). We hold investments to satisfy the future obligations of the plan. Changes in the value of the investment accounts are recognized each period based on the fair value of the underlying investments. Employees making deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)). (4) We estimate the fair value of our long-term debt using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. (5) Contingent consideration obligations arise from prior business acquisitions. The fair values are based on discounted cash flow analyses reflecting the possible achievement of specified performance measures or events and captures the contractual nature of the contingencies, commercial risk, and the time value of money. Contingent consideration obligations are classified in the consolidated balance sheets as accrued expense (short-term) and other liabilities (long-term), as appropriate based on the contractual payment dates. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets. Reference 1: http://www.xbrl.org/2003/role/presentationRef

This element represents the amount of any change, including any differences arising upon settlement, recognized during the reporting period in the value of a liability, arising from an item of contingent consideration, assumed in a business combination.

- Definition
This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets. Reference 1: http://www.xbrl.org/2003/role/presentationRef
