Notes To Financial Statements [Abstract]
Nature of Operations	Nature of Operations and Summary of Significant Accounting Policies Nature of Operations STERIS plc (“Parent”) was organized in 2014 under the name Solar New HoldCo Limited as a private limited company for the purpose of effecting under the laws of England and Wales the combination (“Combination”) of STERIS Corporation, an Ohio corporation (“Old STERIS”), and Synergy Health plc, a public limited company organized under the laws of England and Wales (“Synergy”). Effective November 2, 2015 the Parent was re-registered as a public company under the name STERIS plc and the Combination closed. As a result of the Combination closing, STERIS plc became the ultimate parent company of Old STERIS and Synergy. Synergy has been re-registered under the name of Synergy Health Limited. STERIS offers Customers capital equipment products, such as sterilizers and surgical tables; connectivity solutions such as operating room integration; consumable products, such as detergents, gastrointestinal endoscopy accessories, barrier product solutions, and other products and services, including: equipment installation and maintenance, microbial reduction of medical devices, instrument and scope repair solutions, among other services. Our fiscal year ends on March 31. References in this Quarterly 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: Interim Financial Statements We prepared the accompanying unaudited consolidated financial statements of the Company according to accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. This means that they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Our unaudited interim consolidated financial statements contain all material adjustments (including normal recurring accruals and adjustments) management believes are necessary to fairly state our financial condition, results of operations, and cash flows for the periods presented. These interim consolidated financial statements should be read together with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended March 31, 2017 dated May 26, 2017 . The Consolidated Balance Sheet at March 31, 2017 was derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Principles of Consolidation We use the consolidation method to report our investment in our subsidiaries. Therefore, 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. Investments in equity of unconsolidated affiliates, over which the Company has significant influence, but not control, over the financial and operating polices, are accounted for primarily using the equity method. These investments are immaterial to the Company's Consolidated Financial Statements. Use of Estimates We make certain estimates and assumptions when preparing financial statements according to U.S. GAAP that affect the reported amounts of assets and liabilities at the financial statement dates and the reported amounts of revenues and expenses during the periods presented. These estimates and assumptions involve judgments with respect to many factors that are difficult to predict and are beyond our control. Actual results could be materially different from these estimates. We revise the estimates and assumptions as new information becomes available. This means that operating results for the three and six month periods ended September 30, 2017 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year ending March 31, 2018. Recently Issued Accounting Standards Impacting the Company Recently issued accounting standards impacting the Company are presented in the following table: Standard Date of Issuance Description Date of Adoption Effect on the financial statements or other significant matters Standards that have recently been adopted ASU 2016-07, "Investments - Equity Method and Joint Ventures, Simplifying the Transition to the Equity Method of Accounting" (Topic 323) March 2016 The update replaces the previous requirement to retroactively adopt the equity method. The new standard requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The standard is effective for annual periods beginning after December 15, 2016 and interim periods within that period. Early adoption is permitted. First Quarter Fiscal 2018 The prospective adoption of this standard did not have a material impact on our consolidated statements of financial position, results of operations and cash flows. ASU 2015-11, "Inventory - Simplifying the Measurement of Inventory" (Topic 330) July 2015 The standard requires an entity to measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted. First Quarter Fiscal 2018 The prospective adoption of this standard did not have a material impact on our consolidated statements of financial position, results of operations and cash flows. Standards that have yet to be adopted ASU 2014-09, "Revenue from Contracts with Customers" and subsequently issued amendments May 2014 The standard will replace existing revenue recognition standards and significantly expand the disclosure requirements for revenue arrangements. It may be adopted either retrospectively or on a modified retrospective basis to new contracts and existing contracts with remaining performance obligations as of the effective date. The standard update is effective for annual periods beginning after December 15, 2017 and interim periods within that period. Early adoption is not permitted before the original public entity effective date of December 15, 2016. N/A We have started the implementation process, including a review of Customer contracts, and we are continuing to evaluate and quantify the potential impacts that the standard may have on our consolidated statements of financial position, results of operations, and related disclosures. We currently anticipate adopting this standard using the modified-retrospective method. ASU 2016-01, "Financial Instruments - Overall - Recognition and Measurement of Financial Assets and Liabilities" January 2016 The standard changes how equity investments are measured and the presentation of changes in the fair value of financial liabilities measured under the fair value option. Presentation and disclosure requirements for financial instruments are also affected. Entities will be required to measure equity investments that do not result in consolidation and are not recorded under the equity method at fair value with changes in fair value recognized in net income. The standard clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale securities. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position, results of operations and cash flows. ASU 2016-02, "Leases" (Topic 842) February 2016 The update will require lessees to record all leases, whether finance or operating, on the balance sheet. An asset will be recorded to represent the right to use the leased asset, and a liability will be recorded to represent the lease obligation. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within that period. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position, results of operations and cash flows. ASU 2016-15, "Statement of Cash Flows" (Topic 230) August 2016 This update provides guidance on the following several specific cash flow issues: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. The standard is effective for annual periods beginning after December 15, 2017 and interim periods within that period. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statement of cash flows. ASU 2016-16, "Income Taxes, Intra-Entity Transfers of Assets Other Than Inventory" October 2016 The update improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The new standard requires the recognition of income tax consequences resulting from an intra-entity transfer of an asset other than inventory when the transfer occurs. The standard is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated financial statements. ASU 2017-04, "Intangibles - Goodwill and Other, Simplifying the Test for Goodwill Impairment" (Topic 350) January 2017 This update eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedures that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments of this standard, an entity would perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The loss should not exceed the total amount of goodwill allocated to that reporting unit. Tax effects should be considered. The standard is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. N/A We are in process of evaluating the impact that the standard will have on our annual goodwill impairment test. ASU 2017-07 "Compensation - Retirement Benefits - Improving the Presentation of Net Periodic Pension and Net Periodic Postretirement Benefit Cost" (Topic 715) March 2017 This standard requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside the subtotal of income from operations, if one is presented. The standard is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position and results of operations. ASU 2017-09 "Compensation - Stock Compensation" (Topic 718) May 2017 The update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This standard is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position, results of operations and cash flows. A detailed description of our significant and critical accounting policies, estimates, and assumptions is included in our consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2017 dated May 26, 2017 . Our significant and critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2017 .

Inventories, Net	Inventories, Net We use the last-in, first-out (“LIFO”) and first-in, first-out (“FIFO”) cost methods to value inventory. Inventory valued using the LIFO cost method is stated at the lower of cost or market. Inventory valued using the FIFO cost method is stated at the lower of cost or net realizable value. An actual valuation of inventory under the LIFO method is made only at the end of the fiscal year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and are subject to the final fiscal year-end LIFO inventory valuation. Inventory costs include material, labor, and overhead. Inventories, net consisted of the following: September 30, March 31, Raw materials $ 73,961 $ 65,300 Work in process 30,933 26,538 Finished goods 158,265 140,559 LIFO reserve (17,640 ) (16,706 ) Reserve for excess and obsolete inventory (20,724 ) (17,854 ) Inventories, net $ 224,795 $ 197,837

Income Tax Disclosure [Abstract]
Income Tax Expense	Income Tax Expense The effective income tax rates for the three month periods ended September 30, 2017 and 2016 were 26.2% and 31.8% , respectively. The effective income tax rates for the six month periods ended September 30, 2017 and 2016 were 24.1% and 27.0% , respectively. During the prior year, the tax rates were higher due to non-deductible losses on divestitures. Income tax expense is provided on an interim basis based upon our estimate of the annual effective income tax rate, adjusted each quarter for discrete items. In determining the estimated annual effective income tax rate, we analyze various factors, including projections of our annual earnings and taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, our ability to use tax credits and net operating loss carry forwards, and available tax planning alternatives. We operate in numerous taxing jurisdictions and are subject to regular examinations by various United States federal, state and local, as well as non-United States jurisdictions. We are no longer subject to United States federal examinations for years before fiscal 2015 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 2012. 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 effect on our consolidated financial statements.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	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 effect 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. 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. Civil, criminal, regulatory or other proceedings involving our products or services 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 effect our business, performance, prospects, value, financial condition, and results of operations. For additional information regarding these matters, see the following portions of our Annual Report on Form 10-K for the year ended March 31, 2017 dated May 26, 2017 : Item 1 titled “Business - Information with respect to our Business in General - Government Regulation”, and the “Risk Factors” in Item 1A titled "Product related regulations and claims". 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 non-U.S. 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. We describe income taxes further in Note 7 to our consolidated financial statements titled, “Income Tax Expense” in this Quarterly Report on Form 10-Q. Additional information regarding our contingencies is included in Item 2 titled, “Management’s Discussion and Analysis of Financial Conditions and Results of Operations" under "Contingencies".

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information We operate and report our financial information in four reportable business segments: Healthcare Products, Healthcare Specialty Services, Life Sciences, and Applied Sterilization Technologies. Corporate, which is presented separately, contains costs that are associated with being a publicly traded company and certain other corporate costs. Our Healthcare Products segment offers infection prevention and procedural solutions for healthcare providers worldwide, including consumable products, equipment maintenance and installation services, and capital equipment. Our Healthcare Specialty Services segment provides a range of specialty services for healthcare providers including hospital sterilization services, and instrument and scope repairs. Linen Management Services were divested in fiscal 2017. Our Life Sciences segment offers consumable products, equipment maintenance and specialty services for pharmaceutical manufacturers and research facilities, and capital equipment. Our Applied Sterilization Technologies segment offers contract sterilization and laboratory services for medical device and pharmaceutical Customers and others. Certain minor organizational changes were made to better align with our Customers, resulting in several smaller operations shifting among the segments. The prior period revenues and operating income measures have been recast for comparability. The accounting policies for reportable segments are the same as those for the consolidated Company. Management evaluates performance and allocates resources based on a segment operating income measure. Operating income (loss) for each segment is calculated as the segment’s gross profit less direct expenses and indirect cost allocations, which result 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. Products and services are transferred between segments at cost. Corporate includes certain unallocated corporate costs related to being a publicly traded company and legacy pension and post-retirement benefits. Segment operating income excludes certain adjustments which include acquisition related costs, amortization of acquired intangibles, restructuring costs and other charges that management believes may or may not recur with similar materiality or impact on operating income in future periods. Management believes that by excluding these items they gain better insight and greater transparency of the operating performance of the segments, thus aiding them in more meaningful financial trend analysis and operational decision making. For the three and six months ended September 30, 2017 , revenues from a single Customer did not represent ten percent or more of any reportable segment’s revenues. Additional information regarding our segments is included in our consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2017 , dated May 26, 2017 .

Earnings Per Share [Abstract]
Earnings Per Share	Ordinary shares We calculate basic earnings per share based upon the weighted average number of shares outstanding. We calculate diluted earnings per share based upon the weighted average number of shares outstanding plus the dilutive effect of share equivalents calculated using the treasury stock method. The following is a summary of shares and share equivalents outstanding used in the calculations of basic and diluted earnings per share: Three Months Ended September 30, Six Months Ended September 30, Denominator (shares in thousands): 2017 2016 2017 2016 Weighted average shares outstanding—basic 85,199 85,851 85,145 85,944 Dilutive effect of share equivalents 670 482 650 482 Weighted average shares outstanding and share equivalents—diluted 85,869 86,333 85,795 86,426 Options to purchase the following number of 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 shares during the periods, so including these options would be anti-dilutive: Three Months Ended September 30, Six Months Ended September 30, (shares in thousands) 2017 2016 2017 2016 Number of share options 416 627 492 496 Preferred Shares Pursuant to an engagement letter dated October 23, 2015, we issued 100,000 preferred shares, par value of £0.10 each, for an aggregate consideration of approximately $15 , in satisfaction of debt owed to a service provider. The holders of the preferred shares are entitled to a fixed cumulative preferential annual dividend of 5 percent on the amount paid periodically on the preferred shares respectively held by them. On a return of capital of the Company whether on liquidation or otherwise, the holders of the preferred shares shall be entitled to receive the sum of £0.10 per preferred share plus any accrued but unpaid dividends out of the assets of the Company available for distribution to its shareholders, but will not be entitled to any further participation in the assets of the Company. The holders of the preferred shares will have no right to attend, speak or vote, whether in person or by proxy, at any general meeting of the Company or any meeting of a class of members of the Company in respect of the preferred shares and will not be entitled to receive any notice of meetings.

Repurchases of shares	Repurchases of Ordinary Shares On August 9, 2016, the Company announced that its Board of Directors had authorized the purchase of up to $300 million of our ordinary shares. We may enter into share repurchase contracts until August 2, 2021 to effect these purchases. Shares may be repurchased from time to time through open market transactions, including 10b5-1 plans. The repurchase program may be suspended or discontinued at any time. During the first half of fiscal 2018 , we repurchased 184,547 of our ordinary shares for the aggregate amount of $15,685 pursuant to this authorization. During the first half of fiscal 2018 , we obtained 101,135 of our ordinary shares in the aggregate amount of $5,600 in connection with share based compensation award programs.

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 shares for grants, at the discretion of the Compensation Committee of the Board of Directors, or the Board of Directors, to officers, directors, and key employees in the form of stock options, restricted shares, restricted share units, stock appreciation rights and share grants. We satisfy share award incentives through the issuance of new ordinary shares. Stock options provide the right to purchase our shares at the market price on the date of grant, subject to the terms of the option plan 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 in some cases earlier if the option holder is no longer employed by us. Restricted shares and restricted share units generally cliff vest after a 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 September 30, 2017 , 4,995,098 shares remained available for grant under the long-term incentive plan. The fair value of stock option 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 the first six months of fiscal 2018 and 2017: Fiscal 2018 Fiscal 2017 Risk-free interest rate 2.01% 1.29% Expected life of options 5.7 years 5.7 years Expected dividend yield of stock 1.58% 1.54% Expected volatility of stock 22.08% 22.92% 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 2.25% and 1.85% was applied in fiscal 2018 and 2017 , 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: Number of Options Weighted Average Exercise Price Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at March 31, 2017 1,945,274 $ 50.28 Granted 429,360 77.75 Exercised (227,914 ) 34.53 Forfeited (15,817 ) 66.56 Outstanding at September 30, 2017 2,130,903 $ 57.38 6.9 years $ 66,102 Exercisable at September 30, 2017 1,241,541 $ 47.50 5.5 years $ 50,776 We estimate that 865,781 of the non-vested stock options outstanding at September 30, 2017 will ultimately vest. The aggregate intrinsic value in the table above represents the total pre-tax difference between the $88.40 closing price of our ordinary shares on September 30, 2017 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 ordinary shares. The total intrinsic value of stock options exercised during the first six months of fiscal 2018 and fiscal 2017 was $10,243 and $3,386 , respectively. Net cash proceeds from the exercise of stock options were $7,726 and $2,494 for the first six months of fiscal 2018 and fiscal 2017 , respectively. The weighted average grant date fair value of stock option grants was $15.51 and $13.42 for the first six months of fiscal 2018 and fiscal 2017 , 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 therefore, are classified as liabilities. The fair value of the outstanding SARS as of September 30, 2017 and 2016 was $1,853 and $2,001 , respectively. A summary of the non-vested restricted share and share unit activity is presented below: Number of Restricted Shares Number of Restricted Share Units Weighted-Average Grant Date Fair Value Non-vested at March 31, 2017 780,526 34,013 $ 60.87 Granted 224,169 23,259 77.53 Vested (189,141 ) (19,676 ) 53.42 Forfeited (27,151 ) (660 ) 68.45 Non-vested at September 30, 2017 788,403 36,936 $ 67.51 Restricted shares granted are valued based on the closing stock price at the grant date. The value of restricted shares and units that vested during the first six months of fiscal 2018 was $11,155 . As of September 30, 2017 , there was a total of $44,525 in unrecognized compensation cost related to non-vested share-based compensation granted under our share-based compensation plan. We expect to recognize the cost over a weighted average period of 2.31 years .

Product Warranties Disclosures [Abstract]
Product Warranty Disclosure	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 first half of fiscal 2018 were as follows: Warranties Balance, March 31, 2017 $ 6,861 Warranties issued during the period 5,668 Settlements made during the period (5,953 ) Balance, September 30, 2017 $ 6,576 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 $32,955 and $32,136 as of September 30, 2017 and March 31, 2017 , 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 revenue is excluded from the table presented above.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure	Derivatives and Hedging 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 may also enter into commodity swap contracts to hedge price changes in nickel that impact raw materials included in our cost of revenues. During the first quarter of fiscal 2018, we also entered into forward foreign currency contracts in order to hedge a portion of our expected non-U.S. dollar denominated earnings against our reporting currency, the U.S. dollar. These foreign currency exchange contracts will mature during fiscal 2018. We did not elect hedge accounting for these forward foreign currency contracts; however, we may seek to apply hedge accounting in future scenarios. We do not use derivative financial instruments for speculative purposes. None of these contracts are 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 September 30, 2017 , we held foreign currency forward contracts to buy 127.2 million Mexican pesos, 16.4 million Canadian dollars and 7.7 million Brazilian reais; and to sell 7.7 million euros and 3.2 million British pounds sterling. At September 30, 2017 , we held commodity swap contracts to buy 310.1 thousand pounds of nickel.

We designate portions of foreign currency denominated intercompany loans as hedges of portions of net investments in foreign operations. Net debt designated as non-derivative net investment hedging instruments totaled $65.1 million at September 30, 2017 . These hedges are designed to be fully effective and any associated gain or loss is recognized in Accumulated Other Comprehensive Income and will be reclassified to income in the same period when a gain or loss related to the net investment in the foreign operation is included in income.

Fair Value Disclosures [Abstract]
Fair Value, Measurement Inputs, Disclosure [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 September 30, 2017 and March 31, 2017 : Fair Value Measurements Carrying Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Level 1 Level 2 Level 3 September 30 March 31 September 30 March 31 September 30 March 31 September 30 March 31 Assets: Cash and cash equivalents $ 295,628 $ 282,918 $ 295,628 $ 282,918 $ — $ — $ — $ — Forward and swap contracts (1) 502 160 — — 502 160 — — Investments (2) $ 15,610 12,552 15,610 12,552 — — — — Liabilities: Forward and swap contracts (1) $ 1,247 $ 35 $ — $ — $ 1,247 $ 35 $ — $ — Deferred compensation plans (2) 1,732 1,677 1,732 1,677 — — — — Long term debt (3) $ 1,445,297 1,478,361 — — $ 1,463,984 1,496,966 — — Contingent consideration obligations (4) 8,336 4,451 — — — — 8,336 4,451 (1) 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. (2) We maintain a frozen domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of payment of previously earned 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 who made deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)). We also hold an investment in the common stock of Servizi Italia, S.p.A, a leading provider of integrated linen washing and outsourced sterile processing services to hospital Customers. Changes in the value of the investment are recognized each period based on the fair value of the investment. (3) 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. (4) Contingent consideration obligations arise from 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 September 30, 2017 are summarized as follows: Contingent Consideration Balance at March 31, 2017 $ 4,451 Additions 5,310 Payments (1,535 ) Currency translation adjustments 110 Balance at September 30, 2017 $ 8,336 Information regarding our investments is as follows: Investments at September 30, 2017 and March 31, 2017 Cost Unrealized Gains (2) Unrealized Losses (2) Fair Value September 30 March 31 September 30 March 31 September 30 March 31 September 30 March 31 Available-for-sale securities: Marketable equity securities and other (1) $ 11,037 $ 11,037 $ 2,939 $ — $ — $ (72 ) $ 13,976 $ 10,965 Mutual funds 1,059 1,091 575 496 — — 1,634 1,587 Total available-for-sale securities $ 12,096 $ 12,128 $ 3,514 $ 496 $ — $ (72 ) $ 15,610 $ 12,552 (1) Our marketable equity securities have been in a unrealized loss position for less than 12 months.

Nature of Operations and Summary of Significant Accounting Policies Accounting Policies (Policies)	6 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation We use the consolidation method to report our investment in our subsidiaries. Therefore, 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. Investments in equity of unconsolidated affiliates, over which the Company has significant influence, but not control, over the financial and operating polices, are accounted for primarily using the equity method. These investments are immaterial to the Company's Consolidated Financial Statements.
Use of Estimates	Use of Estimates We make certain estimates and assumptions when preparing financial statements according to U.S. GAAP that affect the reported amounts of assets and liabilities at the financial statement dates and the reported amounts of revenues and expenses during the periods presented. These estimates and assumptions involve judgments with respect to many factors that are difficult to predict and are beyond our control. Actual results could be materially different from these estimates. We revise the estimates and assumptions as new information becomes available. This means that operating results for the three and six month periods ended September 30, 2017 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year ending March 31, 2018.
Recently Issued Accounting Standards Impacting the Company	Recently Issued Accounting Standards Impacting the Company Recently issued accounting standards impacting the Company are presented in the following table: Standard Date of Issuance Description Date of Adoption Effect on the financial statements or other significant matters Standards that have recently been adopted ASU 2016-07, "Investments - Equity Method and Joint Ventures, Simplifying the Transition to the Equity Method of Accounting" (Topic 323) March 2016 The update replaces the previous requirement to retroactively adopt the equity method. The new standard requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The standard is effective for annual periods beginning after December 15, 2016 and interim periods within that period. Early adoption is permitted. First Quarter Fiscal 2018 The prospective adoption of this standard did not have a material impact on our consolidated statements of financial position, results of operations and cash flows. ASU 2015-11, "Inventory - Simplifying the Measurement of Inventory" (Topic 330) July 2015 The standard requires an entity to measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and should be applied prospectively. Early adoption is permitted. First Quarter Fiscal 2018 The prospective adoption of this standard did not have a material impact on our consolidated statements of financial position, results of operations and cash flows. Standards that have yet to be adopted ASU 2014-09, "Revenue from Contracts with Customers" and subsequently issued amendments May 2014 The standard will replace existing revenue recognition standards and significantly expand the disclosure requirements for revenue arrangements. It may be adopted either retrospectively or on a modified retrospective basis to new contracts and existing contracts with remaining performance obligations as of the effective date. The standard update is effective for annual periods beginning after December 15, 2017 and interim periods within that period. Early adoption is not permitted before the original public entity effective date of December 15, 2016. N/A We have started the implementation process, including a review of Customer contracts, and we are continuing to evaluate and quantify the potential impacts that the standard may have on our consolidated statements of financial position, results of operations, and related disclosures. We currently anticipate adopting this standard using the modified-retrospective method. ASU 2016-01, "Financial Instruments - Overall - Recognition and Measurement of Financial Assets and Liabilities" January 2016 The standard changes how equity investments are measured and the presentation of changes in the fair value of financial liabilities measured under the fair value option. Presentation and disclosure requirements for financial instruments are also affected. Entities will be required to measure equity investments that do not result in consolidation and are not recorded under the equity method at fair value with changes in fair value recognized in net income. The standard clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale securities. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position, results of operations and cash flows. ASU 2016-02, "Leases" (Topic 842) February 2016 The update will require lessees to record all leases, whether finance or operating, on the balance sheet. An asset will be recorded to represent the right to use the leased asset, and a liability will be recorded to represent the lease obligation. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within that period. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position, results of operations and cash flows. ASU 2016-15, "Statement of Cash Flows" (Topic 230) August 2016 This update provides guidance on the following several specific cash flow issues: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. The standard is effective for annual periods beginning after December 15, 2017 and interim periods within that period. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statement of cash flows. ASU 2016-16, "Income Taxes, Intra-Entity Transfers of Assets Other Than Inventory" October 2016 The update improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The new standard requires the recognition of income tax consequences resulting from an intra-entity transfer of an asset other than inventory when the transfer occurs. The standard is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated financial statements. ASU 2017-04, "Intangibles - Goodwill and Other, Simplifying the Test for Goodwill Impairment" (Topic 350) January 2017 This update eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedures that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments of this standard, an entity would perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The loss should not exceed the total amount of goodwill allocated to that reporting unit. Tax effects should be considered. The standard is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. N/A We are in process of evaluating the impact that the standard will have on our annual goodwill impairment test. ASU 2017-07 "Compensation - Retirement Benefits - Improving the Presentation of Net Periodic Pension and Net Periodic Postretirement Benefit Cost" (Topic 715) March 2017 This standard requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside the subtotal of income from operations, if one is presented. The standard is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position and results of operations. ASU 2017-09 "Compensation - Stock Compensation" (Topic 718) May 2017 The update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This standard is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. N/A We are in the process of evaluating the impact that the standard will have on our consolidated statements of financial position, results of operations and cash flows.

(2) We maintain a frozen domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of payment of previously earned 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 who made deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)). We also hold an investment in the common stock of Servizi Italia, S.p.A, a leading provider of integrated linen washing and outsourced sterile processing services to hospital Customers. Changes in the value of the investment are recognized each period based on the fair value of the investment. (3) 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. (4) Contingent consideration obligations arise from 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.

[1]	(1) 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.
[2]	We maintain a frozen domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of payment of previously earned 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 who made deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)). We also hold an investment in the common stock of Servizi Italia, S.p.A, a leading provider of integrated linen washing and outsourced sterile processing services to hospital Customers. Changes in the value of the investment are recognized each period based on the fair value of the investment.
[3]	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.
[4]	Contingent consideration obligations arise from 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.
