Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	(2) Summary of Significant Accounting Policies  (a) Basis of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation.  The preparation of financial statements in conformity with U.S. generally accounting principles requires management estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from management’s estimates. (b) Revenue Recognition We generally record revenue on product sales at the time of shipment, which is when title transfers to the customer. We do not record revenue on product sales which require customer acceptance until we receive acceptance. We initially defer service revenue received in advance from service contracts and recognize that deferred revenue ratably over the life of the service contract. We initially defer revenue we receive in advance from rental unit contracts and recognize that deferred revenue ratably over the life of the rental contract. Otherwise, we recognize revenue from rental unit contracts ratably over the life of the rental contract. We include in revenue freight charges we bill to customers. We charge all freight-related expenses to cost of sales. Taxes assessed by government authorities that are imposed on and concurrent with revenue-producing transactions, such as sales and value added taxes, are excluded from revenue.  We do not recognize revenues to the extent that we offer a right of return or other recourse with respect to the sale of our products, other than returns for product defects or other warranty claims, nor do we recognize revenues if we offer variable sale prices for subsequent events or activities. However, as part of our sales processes we may provide upfront discounts for large orders, one-time special pricing to support new product introductions, sales rebates for centralized purchasing entities or price-breaks for regular order volumes. We record the costs of all such programs as an adjustment to revenue at the time the related revenue is recognized. Our products are predominantly therapy-based equipment and require no installation. Therefore, we have no installation obligations. For multiple-element arrangements, we allocate arrangement consideration to the deliverables by use of the relative selling price method. The selling price used for each deliverable is based on vendor–specific objective evidence.  We also generate revenue from time-based licensing of our software and associated services. In most instances, revenue is generated under sales agreements with multiple elements comprising subscription fees and professional services, which typically have contract terms of one to three years. We evaluate each element in these multiple-element arrangements to determine whether they represent a separate unit of accounting and recognize each element as the services are performed.  (c) Cash and Cash Equivalents Cash equivalents include certificates of deposit and other highly liquid investments and we state them at cost, which approximates market. We consider investments with original maturities of 90 days or less to be cash equivalents for purposes of the consolidated statements of cash flows.  Our cash and cash equivalents balance at June 30, 2017 , include $276.5 million in cash which is subject to notice periods of up to 90 days. The se cash balances earn interest rates above normal term deposit rates otherwise available and are held at highly rated financial institutions.  (d) Inventories We state inventories at the lower of cost (determined principally by the first-in, first-out method) or net realizable value. We include material, labor and manufacturing overhead costs in finished goods and work-in-process inventories. We review and provide for any product obsolescence in our manufacturing and distribution operations by assessing throughout the year individual products and components (based on estimated future usage and sales).  (e) Property, Plant and Equipment We record property, plant and equipment, including rental and demonstration equipment at cost. We compute depreciation expense using the straight-line method over the estimated useful lives of the assets. Useful lives are generally two to ten years except for buildings which are depreciated over an estimated useful life of 40 years and leasehold improvements, which we amortize over the lease term. We charge maintenance and repairs to expense as we incur them. (f) Intangible Assets We capitalize the registration costs for new patents and amortize the costs over the estimated useful life of the patent, which is generally five years. If a patent is superseded or a product is retired, any unamortized costs are written off immediately.  We amortize all of our other intangible assets on a straight-line basis over their estimated useful lives, which range from two to fifteen years. We evaluate the recoverability of intangible assets periodically and take into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists. We have not identified any impairment of intangible assets during any of the periods presented. (g) Goodwill We conducted our annual review for goodwill impairment during the final quarter of the year ended June 30, 2017 . Our goodwill impairment tests are performed at our reporting unit level which is one level below our operating segment. Fair value is determined based on estimated discounted cash flows. Our goodwill impairment review involved the following steps: Step 0 or Qualitative assessment – Evaluate qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Factors considered included, but were not limited to, macroeconomic conditions, industry and market considerations, cost factors, overall financial performance or events-specific to that reporting unit. If or when we determine it is more likely than not that the fair value of a reporting unit is less than the carrying amount, including goodwill, we would move to Step 1 of the quantitative method.  Step 1 - Compare the fair value for each reporting unit to its carrying value, including goodwill. For each reporting unit where the carrying value, including goodwill, exceeds the reporting unit’s fair value, move on to Step 2. If a reporting unit’s fair value exceeds the carrying value, no further work is performed and no impairment charge is necessary.  Step 2 - Allocate the fair value of the reporting unit to its identifiable tangible and non-goodwill intangible assets and liabilities. This will derive an implied fair value for the goodwill. Then, compare the implied fair value of the reporting unit’s goodwill with the carrying amount of the reporting unit’s goodwill. If the carrying amount of the reporting unit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess.  The results of our review indicated that no impaired goodwill exists as the fair value for each reporting unit exceeded its carrying value. (h) Foreign Currency The consolidated financial statements of our non-U.S. subsidiaries, whose functional currencies are other than the U.S. dollar, are translated into U.S. dollars for financial reporting purposes. We translate assets and liabilities of non-U.S. subsidiaries whose functional currencies are other than the U.S. dollar at period end exchange rates, but translate revenue and expense transactions at average exchange rates for the period. We recognize cumulative translation adjustments as part of comprehensive income, as detailed in the consolidated statements of comprehensive income, and include those adjustments in accumulated other comprehensive income in the consolidated balance sheets until such time the relevant subsidiary is sold or substantially or completely liquidated. We reflect gains and losses on transactions denominated in other than the functional currency of an entity in our results of operations.  (i) Research and Development We record all research and development expenses in the period we incur them. (j) Financial Instruments The carrying value of financial instruments, such as cash equivalents, accounts receivable and accounts payable, approximate their fair value because of their short-term nature. The carrying value of long-term debt approximates its fair value as the principal amounts outstanding are subject to variable interest rates that are based on market rates which are regularly reset. Foreign currency hedging instruments are marked to market and therefore reflect their fair value. We do not hold or issue financial instruments for trading purposes. The fair value of financial instruments is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. (k) Foreign Exchange Risk Management We enter into various types of foreign exchange contracts in managing our foreign exchange risk, including derivative financial instruments encompassing forward exchange contracts and foreign currency options. The purpose of our foreign currency hedging activities is to protect us from adverse exchange rate fluctuations with respect to net cash movements resulting from the sales of products to foreign customers and Australian and Singapore manufacturing activities. We enter into foreign exchange contracts to hedge anticipated sales and manufacturing costs, principally denominated in Australian and Singapore dollars, and Euros. The terms of such foreign exchange contracts generally do not exceed three years. We have determined our hedge program to be a non-effective hedge as defined. We record the foreign currency derivatives portfolio at fair value and include it in other assets and accrued expenses in our consolidated balance sheets. We do not offset the fair value amounts recognized for foreign currency derivatives. We classify purchases of foreign currency derivatives and proceeds received from the exercise of foreign currency derivatives as an investing activity within our consolidated statements of cash flows. We record all movements in the fair value of the foreign currency derivatives within other income, net in our consolidated statements of income.  (l) Income Taxes We account for income taxes under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using the enacted tax rates we expect to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  (m) Provision for Warranty We provide for the estimated cost of product warranties at the time the related revenue is recognized. We determine the amount of this provision by using a financial model, which takes into consideration actual historical expenses and potential risks associated with our different products. We use this financial model to calculate the future probable expenses related to warranty and the required level of the warranty provision. Although we engage in product improvement programs and processes, our warranty obligation is affected by product failure rates and costs incurred to correct those product failures. Should actual product failure rates or estimated costs to repair those product failures differ from our estimates, we would be required to revise our estimated warranty provision.  ( n ) Allowance for Doubtful Accounts We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments, which results in bad debt expense. We determine the adequacy of this allowance by periodically evaluating individual customer receivables, considering a customer’s financial condition, credit history and current economic conditions. We are also contingently liable, within certain limits, in the event of a customer default, to independent leasing companies in connection with customer leasing programs. We monitor the collection status of these installment receivables and provide for estimated losses separately under accrued expenses within our consolidated balance sheets based upon our historical collection experience with such receivables and a current assessment of our credit exposure.  ( o ) Impairment of Long-Lived Assets We periodically evaluate the carrying value of long-lived assets to be held and used, including certain identifiable intangible assets, when events and circumstances indicate that the carrying amount of an asset may not be recovered. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If assets are considered to be impaired, we recognize as the impairment the amount by which the carrying amount of the assets exceeds the fair value of the assets. We report assets to be disposed of at the lower of the carrying amount or fair value less costs to sell.  We did not recognize impairment charges in relation to long-lived assets during the fiscal years ended June 30, 2017 and 2015, but during the fiscal year ended June 30, 2016 , we recognized $ 2.8 million of impairment charges.  ( p ) Contingencies  We record a liability in the consolidated financial statements for loss contingencies when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. When determining the estimated loss or range of loss, significant judgment is required to estimate the amount and timing of a loss to be recorded.

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	(3) New Accounting Pronouncements  (a) Recently issued accounting standards not yet adopted  ASU No. 2014-09, “Revenue from Contracts with Customers” In May, 2014, the FASB issued Accounting Standards Update (ASU), ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Since its initial release, the FASB has issued several amendments to the standard, which include clarification of accounting guidance related to identification of performance obligations, intellectual property licenses, and principal vs. agent considerations. ASU 2014-09 and all subsequent amendments (collectively, the “ new revenue recognition standards ” ) will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The guidance also requires improved disclosures on the nature, amount, timing, and uncertainty of revenue that is recognized.  We formed an implementation team in fiscal year June 30, 2017 to oversee adoption of the new revenue recognition standards. The implementation team has commenced the diagnostic phase of its project which has included composition and detailed review of our contract portfolio and selection of sample contracts for assessment which, we expect to complete in the second quarter of the year ending June 30, 2018 . T here are a number of steps in the team ’ s project plan that remain to be completed including: finalizing contract reviews, evaluating the impact, and working through required changes to systems, business processes and controls to support the adoption of the new revenue recognition standards. W e expect there will be changes to our accounting policies to align with terminology and concepts in the new revenue recognition standards as well as increased disclosures relating to our revenue streams, contract-related balances and contract details.  The new revenue recognition standard is effective for us beginning in the first quarter of the fiscal year ending June 30, 2019 and early application is permitted for annual or interim periods beginning after December 15, 2016 . The new guidance can be applied retrospectively to each prior reporting period presented, or retrospectively with the cumulative effect of the change recognized at the date of the initial application. Assuming the impact is not material, we expect to adopt the new revenue recognition standards using the modified retrospective method with an adjustment to beginning retained earnings for the cumulative effect of the change.  ASU No. 2016-01, "Financial Instruments - Overall" In January 2016, the FASB issued Accounting Standards Update ASU No. 2016-01, "Financial Instruments - Overall" (Topic 825-10). The amendments address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments, and require equity securities to be measured at fair value with changes in fair value recognized through net income. The amendments also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment for impairment quarterly at each reporting period. The amendments in ASU 2016-01 will be effective for our first quarter of the fiscal year ending June 30, 2019. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with prospective adoption of the amendments related to equity securities without readily determinable fair values existing as of the date of adoption. We are currently assessing the impact as this standard will be relevant for our Cost-Method Investments.  ASU No. 2016-02, “Leases” In February 2016, the FASB issued Accounting Standard Update ASU No. 2016-02, “Leases” (Topic 842). Under the new guidance, lessees are required to recognize a right-of-use asset and a lease liability on the balance sheet for all leases, other than those that meet the definition of a short-term lease. This update will establish a lease asset and lease liability by lessees for those leases classified as operating under current GAAP. Leases will be classified as either operating or finance under the new guidance. Operating leases will result in straight-line expense in the income statement, similar to current operating leases, and finance leases will result in more expense being recognized in the earlier years of the lease term, similar to current capital leases. For lessors, the update will more closely align lease accounting to comparable guidance in the new revenue standards described.  The new standard is effective for us beginning in the first quarter of the fiscal year ending June 30, 2020 and early application is not permitted. ASU 2016-02 will be adopted on a modified retrospective transition basis for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the impact of this standard on its consolidated financial statements and expect to commence an implementation project during the fiscal year ending June 30, 2018. While the formal impact assessment has not commenced, we expect this amendment will affect the way we account for operating leases where we are the lessee (as described above), require reassessment of how we account for revenue where we are the lessor and will result in increased disclosures for all lease arrangements.  ASU No. 2016-16 , “ Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory ” In October 2016, the FASB iss ued Accounting Standard Update ASU No. 2016-16, “Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory” (Topic 740). Under the new guidance , an entity is required to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory. ASU 2016-1 6 will be effective for the first quarter of our fiscal year ending June 30, 2019 , with early adoption permitted. I f we enter into transactions within the scope of the standard, it could result in additional deferred tax balances being recognized at the time of the transfer.  (b) Recently adopted accounting pronouncements  ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs" In April, 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs". ASU 2015-03 more closely align s the presentation of debt issuance costs under U.S. GAAP with the presentation under comparable I nternational F inancial R eporting Standards , or IFRS, by requiring that debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability. As of July 1, 2016, we adopted ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs" which amended ASC 835-30, Interest – Imputation of Interest. As a result of the adoption , $2.2 million was reclassified from other assets and $0.6 million and $1.6 million we recognised in short-term debt and long-term debt , respectively in the company’s consolidated balance sheet as of June 30, 2016. The adoption of this guidance did not impact the company’s consolidated statements of income, comprehensive income, stockholders’ equity or cash flows.  ASU No. 2015-11, “Simplifying the Measurement of Inventory” In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory” which requires an entity to measure inventory within the scope of this ASU 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. The amendments in this guidance more closely align the measurement of inventory in GAAP with the measurement of inventory in IFRS. This accounting guidance was effective for us beginning in the first quarter of our fiscal year ending, June 30, 2018, however we have elected to early-adopt this amendment which can only be adopted on a prospective basis. There has been no impact on our consolidated financial statements and related disclosures as a result of this adoption.  ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” On March 30, 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting”, which requires companies to recognize additional tax benefits or expenses related to the vesting or settlement of employee share-based awards (the difference between the actual benefit for tax purposes and the tax benefit initially recognized for financial reporting purposes) as income tax benefit or expense in earnings, rather than in additional paid-in capital, in the reporting period in which they occur. This ASU also requires companies to classify cash flows resulting from employee share-based payments, including the additional tax benefits or expenses related to the vesting or settlement of share-based awards, as cash flows from operating activities rather than financing activities. Although this change will reduce some of the administrative complexities of tracking share-based awards, it will increase the volatility of our income tax expense and cash flows from operations. The new standard is effective for annual reporting periods beginning after December 15, 2016, with early adoption permitted. We elected to early adopt this ASU during the fourth quarter of fiscal year 2016 and we re therefore required to report the impacts as though the ASU had been adopted on July 1, 2015, the beginning of our fiscal year, and to reflect the tax benefit as a discrete item within each of the respective interim reporting periods. Accordingly, we recognized additional income tax benefits as an increase to earnings of $6.1 million and $11.2 million during the year s ended June 30, 2017 and June 30, 2016, respectively. We also recognized additional income tax benefits as an increase to operating cash flows of $9.2 million and $14.5 million for the year s ended June 30, 2017 and June 30, 2016, respectively. The new accounting standard did not impact any periods prior to July 1, 2015, as we applied the changes on a prospective basis.

Earnings Per Share [Abstract]
Earnings Per Share	(4) Earnings Per Share We compute basic earnings per share by dividing the net income available to common stockholders by the weighted average number of shares of common stock outstanding. For purposes of calculating diluted earnings per share, the denominator includes both the weighted average number of shares of common stock outstanding and the number of dilutive common stock equivalents such as stock options and restricted stock units.  The weighted average number of outstanding stock options and restricted stock units not included in the computation of diluted earnings per share were 173,000 , 297,000 a nd 62,000 f or the years ended June 30, 2017, 2016 and 2015 , respectively, as the effect would have been anti-dilutive. Basic and diluted earnings per share for the years ended June 30, 2017, 2016 and 2015 are calculated as follows (in thousands except per share data):    2017 2016 2015  Numerator:  Net Income, used in calculating diluted earnings per share $ 342,284 $ 352,409 $ 352,886   Denominator:  Basic weighted-average common shares outstanding 141,360 140,242 140,468  Effect of dilutive securities:  Stock options and restricted stock units 1,093 1,427 2,219  Diluted weighted average shares 142,453 141,669 142,687  Basic earnings per share $ 2.42 $ 2.51 $ 2.51  Diluted earnings per share $ 2.40 $ 2.49 $ 2.47

Cost-Method Investments [Abstract]
Cost-Method Investments	 (8) Cost-Method Investments  The aggregate carrying amount of our cost-method investments at June 30, 2017 and June 30, 2016 , included within our other long-term assets on our consolidated balance sheets, was $ 38.3 million and $ 33.8 million, respectively.  We periodically evaluate the carrying value of our cost-method investments, when events and circumstances indicate that the carrying amount of an asset may not be recovered. We determine the fair value of our cost-method investments to evaluate whether impairment losses shall be recorded using Level 3 inputs. These investments include our holdings in privately held service and research companies that are not exchange traded and therefore not supported with observable market prices. However, these investments are valued by reference to their net asset values which can be market supported and unobservable inputs including future cash flows. We have determined, that the fair value of our cost-method investments exceed their carrying values.  The following table shows a reconciliation of the changes in our cost-method investments during the years ended June 30, 2017 and June 30, 2016 (in thousands):    2017 2016  Balance at the beginning of the period $ 33,815 $ 25,600  Investments 6,464 8,965  Impairment of investments (1,955) (750)  Balance at the end of the period $ 38,324 $ 33,815

On April 4, 2016, in connection with our acquisition of Brightree LLC (“Brightree”), we entered into a first amendment to the revolving credit agreement to increase the size of the revolving credit facility from $700 million to $1 billion, with an uncommitted option to increase the revolving credit facility by an additional $300 million, and to make other modifications to provide for the acquisition of Brightree. On January 9, 2017, we entered into a second amendment to our agreement with our existing lenders, including MUFG Union Bank, N.A. as successor in interest to Union Bank, N.A., as Administrative Agent, Joint Lead Arranger, Swing Line Lender and L/C Issuer; and HSBC Bank USA, National Association, as Syndication Agent and Joint Lead Arranger. The second amendment, among other things, increases the size of our senior unsecured revolving credit facility from $1.0 billion to $1.3 billion, with an uncommitted option to increase the revolving credit facility by an additional $300 million. The credit facility terminates on October 31, 2018 , when all unpaid principal and interest under the loans must be repaid. The outstanding principal amount due under the credit facility will bear interest at a rate equal to LIBOR plus 1.0% to 2.0% (depending on the then-applicable leverage ratio). At June 30, 2017 , the interest rate that was being charged on the outstanding principal amount was 2.7% . A commitment fee of 0.15% to 0.25% (depending on the then-applicable leverage ratio) applies on the unused portion of the credit facility. The credit facility also includes a $25 million sublimit for letters of credit.  Our obligations under the revolving credit agreement (as amended) are unsecured but are guaranteed by certain of our direct and indirect U. S. subsidiaries, including ResMed Corp., ResMed Motor Technologies Inc., Birdie Inc., Inova Labs, Inc., Brightree, Brightree Services LLC, Brightree Home Health & Hospice LLC and Strategic AR LLC, under an unconditional guaranty. The credit agreement contains customary covenants, including certain financial covenants and an obligation that we maintain certain financial ratios, including a maximum leverage ratio of funded debt to EBITDA (as defined in the credit agreement) and an interest coverage ratio.  At June 30, 2017 , we were in compliance with our debt covenants and there was $ 1,080.0 million outstanding under the revolving credit facility. We expect to satisfy all of our liquidity requirements through a combination of cash on hand, cash generated from operations and debt facilities.  Term Loan  On April 4, 2016, in connection with the Brightree acquisition, we also entered into the term loan credit agreement providing a $300 million senior unsecured one -year term loan credit facility.  The proceeds from the funding of the term loan credit facility were used to pay a portion of the acquisition consideration for the Brightree acquisition, as well as to pay fees and expenses in connection with the acquisition, the amendment to the revolving credit agreement and the t erm l oan c redit a greement. On March 30, 2017 we drew down $300 million from the revolving credit facility to pay off all outstanding amounts under the term loan credit facility, in advance of the scheduled termination of the term loan credit facility on April 3, 2017.

Stockholders' Equity [Abstract]
Stockholders' Equity	(12) Stockholders’ Equity  Common Stock. On February 21, 2014, our board of directors approved a new share repurchase program, authorizing us to acquire up to an aggregate of 20.0 million shares of our common stock. The program allows us to repurchase shares of our common stock from time to time for cash in the open market, or in negotiated or block transactions, as market and business conditions warrant and subject to applicable legal requirements. The 20.0 million shares the new program authorizes us to purchase are in addition to the shares we repurchased on or before February 21, 2014 under our previous programs. There is no expiration date for this program, and the program may be accelerated, suspended, delayed or discontinued at any time at the discretion of our board of directors. All share repurchases since February 21, 2014 have been executed in accordance with this program. We temporarily suspended our share repurchase program due to recent acquisitions. Accordingly, we did no t repurchase any shares during the year ended June 30, 2017 . However, we expect to resume the share repurchase program during fiscal year 2018 . As noted above, we did not repurchase any shares during the year ended June 30, 2017. During the year ended June 30, 2016 , we repurchased 1.9 million shares at a cost of $ 1 0 2. 1 million prior to the temporary suspension of the share repurchase program . As of June 30, 2017 , we have repurchased a total of 41.1 million shares at a cost of $ 1 . 5 billion . Shares that are repurchased are classified as “treasury stock pending future use” and reduce the number of shares outstanding used in calculating earnings per share. At June 30, 2017 , 13.6 million additional shares can be repurchased under the approved share repurchase program.  Preferred Stock. In April 1997, our board of directors authorized 2,000,000 shares of $ 0.01 par value preferred stock. No such shares were issued or outstanding at June 30, 2017 . Stock Options and Restricted Stock Units. We have granted stock options and restricted stock units to personnel, including officers and directors, in accordance with the ResMed Inc. 2009 Incentive Award Plan (the “2009 Plan”). These options and restricted stock units vest over one to four years and the options have expiration dates of seven years from the date of grant. We have granted the options with an exercise price equal to the market value as determined at the date of grant.  The maximum number of shares of our common stock authorized for issuance under the 2009 Plan is 43.7 million . The number of securities remaining available for future issuance under the 2009 Plan at June 30, 2017 is 11.6 million . The number of shares of our common stock available for issuance under the 2009 Plan will be reduced by (i) 2.8 shares for each one share of common stock delivered in settlement of any “full-value award,” which is any award other than a stock option, stock appreciation right or other award for which the holder pays the intrinsic value and (ii) one share for each share of common stock delivered in settlement of all other awards. The maximum number of shares, which may be subject to awards granted under the 2009 Plan to any individual during any calendar year, may not exceed 3 million shares of our common stock (except in a participant’s initial year of hiring up to 4.5 million shares of our common stock may be granted).  At June 30, 2017 , there was $73.2 million in unrecognized compensation costs related to unvested stock-based compensation arrangements. This is expected to be recognized over a weighted average period of 2.3 years. The aggregate intrinsic value of the stock-based compensation arrangements outstanding and exercisable at June 30, 2017 and June 30, 2016 was $194.5 million and $164.9 million, respectively.

Employee Stock Purchase Plan (the “ESPP”). Under the ESPP, we offer participants the right to purchase shares of our common stock at a discount during successive offering periods. Each offering period under the ESPP will be for a period of time determined by the board of directors’ compensation committee of no less than 3 months and no more than 27 months. The purchase price for our common stock under the ESPP will be the lower of 85 % of the fair market value of our common stock on the date of grant or 85 % of the fair market value of our common stock on the date of purchase. An individual participant cannot subscribe for more than $ 25,000 in common stock during any calendar year. At June 30, 2017 , the number of shares remaining available for future issuance under the ESPP is 0.8 million shares.

The valuation allowance at June 30, 2017 relates to a provision for uncertainty of the utilization of net operating loss carryforwards of $12.1 million and capital loss and other items of $3.2 million. We believe that it is more likely than not that the benefits of deferred tax assets, net of any valuation allowance, will be realized.  A substantial portion of our manufacturing operations and administrative functions in Malaysia and Singapore operate under various tax holidays and tax incentive programs that will expire in whole or in part at various dates through June 30, 202 0. The end of c ertain tax holidays may be extended if specific conditions are met. The net impact of these tax holidays and tax incentive programs increased our net earnings by $19.5 million ( $0.14 per diluted share) for the year ended June 30, 2017 and $19.2 million ( $0.14 per diluted share) for the year ended June 30, 2016 .  At June 30, 2017 , applicable U.S. federal income taxes and foreign withholding taxes have not been provided on the accumulated earnings of foreign subsidiaries that are expected to be permanently reinvested. The total amount of these undistributed earnings at June 30, 2017 amounted to approximately $1.5 billion. If these earnings had not been permanently reinvested, deferred taxes of approximately $358 million would have been recognized in the consolidated financial statements.  In accounting for uncertainty in income taxes, we recognize a tax benefit in the financial statements for an uncertain tax position only if management’s assessment is that the position is “more likely than not” (that is, a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term “tax position” refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for annual periods. The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statements of income. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets. Based on all known facts and circumstances and current tax law, we believe the total amount of unrecognized tax benefits on June 30, 2017 , is not material to our results of operations, financial condition or cash flows, and if recognized, would not have a material impact on our effective tax rate .  Our income tax returns are based on calculations and assumptions subject to audit by various tax authorities. In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws. We regularly assess the potential outcomes of examinations by tax authorities in determining the adequacy of our provision for income taxes. We are currently under audit by the Australian Taxation Office for the tax years 2009 to 2013 . Although we do not believe that any material adjustments will result from this audit , the outcome of tax audits cannot be predicted with certainty. Any final assessment resulting from tax audits may result in material changes to our past or future taxable income, tax payable or deferred tax assets, and may require us to pay penalties and interest that could materially adversely affect our financial results.

Segment Information [Abstract]
Segment Information	(15) Segment Information We predominantly operate in a single operating segment, which is the sleep and respiratory disorders sector of the medical device industry. Due to the acquisition of Brightree LLC in April 2016, our operations now include the supply of business management software and services to medical equipment and home health providers. However, these operations, both in terms of revenue and profit, are not material to our global operations and therefore have not been separately reported as a segment.  Sales of device s for each of the years ended June 30, 2017, 2016 and 2015 , were $ 1,161.0 million , $ 1,064.2 million and $ 975.9 million, respectively. Sales of masks and other accessories for each of the years ended June 30, 2017, 2016 and 2015 , were $ 767.7 million , $745.6 million and $703.0 million, respectively. We allocate revenue to a geographic area based on where the products are shipped to or where the services are performed.

Stock-Based Employee Compensation [Abstract]
Stock-Based Employee Compensation	(16) Stock-based Employee Compensation  We measure the compensation expense of all stock-based awards at fair value on the grant date. We estimate the fair value of stock options and purchase rights granted under the ESPP using the Black-Scholes valuation model. The fair value of restricted stock units is equal to the market value of the underlying shares as determined at the grant date less the fair value of dividends that holders are not entitled to, during the vesting period. We recognize the fair value as compensation expense using the straight-line method over the service period for awards expected to vest.  We estimate the fair value of stock options granted under our stock option plans and purchase rights granted under the ESPP using the following assumptions:      Fiscal Year Ended June 30,  2017 2016  Stock options:  Weighted average grant date fair value $ 10.89 $ 12.18  Weighted average risk-free interest rate 1.61% 1.66%  Expected life in years 4.9 4.9  Dividend yield 2.02% - 2.29% 2.06% - 2.09%  Expected volatility 25% 27%  ESPP purchase rights:  Weighted average grant date fair value $ 12.50 $ 13.61  Weighted average risk-free interest rate 0.5% 0.2%  Expected life in years 6 months 6 months  Dividend yield 1.92% - 2.27% 1.96% - 2.14%  Expected volatility 23% 23% - 32%   During the fiscal years ended June 30, 2017 and June 30, 2016 , we granted 243,000 and 208,000, performance restricted stock units (“PRSUs”), which contain a market condition, with the ultimate realizable number of PRSUs dependent on relative total stockholder return over a three -year period, up to a maximum amount to be issued under the award of 200 % of the original grant. The weighted average grant date fair value of PRSUs granted during the fiscal years 2017 and 2016 was estimated at $51.60 and $53.11 per PRSU, respectively, using a Monte-Carlo simulation valuation model.

Legal Actions And Contingencies	(19) Legal Actions and Contingencies  Litigation In the normal course of business, we are subject to routine litigation incidental to our business. While the results of this litigation cannot be predicted with certainty, we believe that their final outcome will not, individually or in aggregate, have a material adverse effect on our consolidated financial statements taken as a whole.  Contingent Obligations Under Recourse Provisions  We use independent leasing companies to provide financing to certain customers for the purchase of our products. In some cases, we are contingently liable in the event of a customer default, to the leasing companies, within certain limits, for unpaid installment receivables transferred to the leasing companies. The gross amount of receivables sold, with recourse, during the fiscal years 2017 and 2016 , amounted to $ 99.3 million and $67.1 million, respectively. The maximum potential amount of contingent liability under these arrangements at June 30, 2017 and June 30, 2016 , were $27.5 million, and $12.9 million, respectively. The recourse liability recognized by us at June 30, 2017 and June 30, 2016 in relation to these arrangements was $1.4 million and $0.7 million, respectively.

Fair Value Measurements [Abstract]
Fair Value Measurements	(20) Fair Value Measurements  In determining the fair value measurements of our financial assets and liabilities, we consider the principal and most advantageous market in which we transact and consider assumptions that market participants would use when pricing the financial asset or liability. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.  The hierarchies of inputs are as follows:  • Level 1: Input prices quoted in an active market for identical financial assets or liabilities;  • Level 2: Inputs other than prices quoted in Level 1, such as prices quoted for similar financial assets and liabilities in active markets, prices for identical assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and  • Level 3: Input prices quoted that are significant to the fair value of the financial assets or liabilities which are not observable nor supported by an active market.  The following table summarizes our financial assets and liabilities, as at June 30, 2017 and June 30, 2016 using the valuation input hierarchy (in thousands):     Level 1 Level 2 Level 3 Total  Balances at June 30, 2017  Foreign currency hedging instruments, net $ - $ 2,760 $ - $ 2,760  Business acquisition contingent consideration $ - $ - $ (1,580) $ (1,580)  Balances at June 30, 2016  Foreign currency hedging instruments, net $ - $ 4,185 $ - $ 4,185  Business acquisition contingent consideration $ - $ - $ (10,450) $ (10,450)  We determine the fair value of our financial assets and liabilities as follows:  Foreign currency options – These financial instruments are valued using third-party valuation models based on market observable inputs, including interest rate curves, on-market spot currency prices, volatilities and credit risk.  Contingent consideration – These liabilities include the fair value estimates of additional future payments that may be required for some of our previous business acquisitions based on the achievement of certain performance milestones. Each potential future payment is valued using the estimated probability of achieving each milestone, which is then discounted to present value.  During the year ended June 30, 2017 we recognized a charge of $10.1 million representing additional contingent consideration associated with the acquisition of Curative Medical Technology Inc. (“Curative Medical”), following the achievement of performance milestones under the purchase agreement which exceeded our earlier expectations.  The following is a reconciliation of changes in the fair value of contingent consideration during fiscal years ended June 30, 2017 and June 30, 2016 (in thousands):    2017 2016  Balance at the beginning of the period $ (10,450) $ (1,584)  Acquisition date fair value of contingent consideration (1,580) (13,107)  Changes in fair value included in operating income (10,076) 2,986  Payments 20,142 1,228  Foreign currency translation adjustments 384 27  Balance at the end of the period $ (1,580) $ (10,450)  We did not have any significant non-financial assets or liabilities measured at fair value on June 30, 2017 or June 30, 2016 .

Derivative Instruments And Hedging Activities [Abstract]
Derivative Instruments And Hedging Activities	(21) Derivative Instruments and Hedging Activities  We transact business in various foreign currencies, including a number of major European currencies as well as the Australian and Singapore dollars. We have significant foreign currency exposure through both our Australian and Singaporean manufacturing activities, and international sales operations. We have established a foreign currency hedging program using purchased currency options and forward contracts to hedge foreign-currency-denominated financial assets, liabilities and manufacturing cash flows. The terms of such foreign currency hedging contracts generally do not exceed three years. The goal of this hedging program is to economically manage the financial impact of foreign currency exposures denominated mainly in Euros, Australian and Singapore dollars . Under this program, increases or decreases in our foreign currency denominated financial assets, liabilities, and firm commitments are partially offset by gains and losses on the hedging instruments. We do not designate these foreign currency contracts as hedges. We have determined our hedge program to be a non-effective hedge as defined under the FASB issued authoritative guidance. All movements in the fair value of the foreign currency instruments are recorded within o ther income, net in our consolidated statements of income and through changes in our operating assets and liabilities within our consolidated statements of cash flows . We do not enter into financial instruments for trading or speculative purposes.  We held foreign currency instruments with notional amounts totaling $ 568.2 million and $ 612.2 million at June 30, 2017 and June 30, 2016 , respectively, to hedge foreign currency fluctuations. These contracts mature at various dates prior to June 30, 201 9 .  The following table summarizes the amount and location of our derivative financial instruments as of June 30, 2017 and June 30, 2016 (in thousands):      June 30, 2017 June 30, 2016 Balance Sheet Caption  Foreign currency hedging instruments $ 2,614 $ 2,346 Other assets - current  Foreign currency hedging instruments 1,273 2,082 Other assets - non current  Foreign currency hedging instruments (1,127) (243) Accrued expenses  $ 2,760 $ 4,185    The following table summarizes the amount and location of gains (losses) associated with our derivative financial instruments and other foreign-currency-denominated transactions for the fiscal year s ended June 30, 2017 and June 30, 2016 , respectively (in thousands):     Gain /(Loss) Recognized Income Statement Caption  Year Ended June 30,  2017 2016  Foreign currency hedging instruments $ 1,812 $ (5,192) Other, net  Other foreign-currency-denominated transactions 3,622 9,361 Other, net  $ 5,434 $ 4,169 Other, net  We are exposed to credit-related losses in the event of non-performance by counter parties to financial instruments.

Business Combinations [Abstract]
Business Combinations	(22) Business Combinations  Fiscal year ended June 30, 2017  On May 31, 2017 , we completed the acquisition of assets in Conduit Technology, LLC (“Conduit”), a provider of documentation and workflow solutions. On June 30, 2017 , we completed the acquisition of assets in AllCall Connect, LLC (“AllCall”), a provider of a live-calling solution for CPAP patient resupply. These acquisitions have been accounted for as business combinations using purchase accounting and are included in our consolidated financial statements from their respective acquisition dates. The acquisitions, individually and collectively, are not considered a material business combination and accordingly pro forma information is not provided. The acquisitions were funded through cash on-hand.  We have not yet completed the purchase price allocations associated with the Conduit and AllCall acquisitions. We expect to complete our Conduit and AllCall purchase price allocations during the quarter ending September 30, 2017. We do not believe that the completion of this work will materially modify the preliminary purchase price allocation for Conduit or AllCall. The cost of the acquisitions was allocated to the assets acquired and liabilities assumed based on estimates of their fair values at the date of acquisition. The goodwill recognized as part of these acquisitions, which is deductible for tax purposes, mainly represents the synergies that are unique to our combined businesses and the potential for new products and services to be developed in the future. The fair values of assets acquired and liabilities assumed, and the estimated useful lives of intangible assets acquired are as follows (in thousands):    Preliminary Intangible assets - useful life  Current assets $ -  Property, plant and equipment 69  Trade names 100 3 years  Non-compete 520 1 - 3 years  Developed technology 1,800 5 years  Customer relationships 2,160 5 years  Goodwill 2,000  Assets acquired $ 6,649  Current liabilities (60)  Total liabilities assumed $ (60)  Net assets acquired $ 6,589  During the year ended June 30, 2017 we did no t record material acquisition-related expenses.  Fiscal year ended June 30, 2016  Brightree  On April 4, 2016 we completed the acquisition of Brightree LLC (“Brightree”), a provider of cloud-based clinical and business management software for the post-acute care industry, for a total purchase consideration paid of $802 million. This acquisition has been accounted for as a business combination using purchase accounting and included in our consolidated financial statements from April 4, 2016. The acquisition was funded through cash on-hand, funds available from the existing revolving credit facility, an increase in the size of our revolving credit facility from $700 million to $1 billion and we also entered into a $300 million senior unsecured one -year term loan credit facility.  We completed the purchase price allocation in relation to this acquisition during the quarter ended March 31, 2017. The cost of the acquisition was allocated to the assets acquired and liabilities assumed based on estimates of their fair values at the date of acquisition. The goodwill recognized as part of these acquisitions, which is deductible for tax purposes, mainly represents the synergies that are unique to our combined businesses and the potential for new products and services to be developed in the future. The fair values of assets acquired and liabilities assumed, and the estimated useful lives of intangible assets acquired, are as follows (in thousands):      Brightree Adjustments Final Intangible assets - useful life  Current assets $ 13,868 1,442 15,310  Property, plant and equipment 1,045 - 1,045  Trade names 28,700 - 28,700 10 years  In-process research and development 4,100 - 4,100 n/a  Developed technology 114,700 - 114,700 5 to 6 years  Customer relationships 51,000 - 51,000 10 to 15 years  Goodwill 602,090 906 602,996  Assets acquired $ 815,503 $ 2,348 $ 817,851  Current liabilities (9,399) - (9,399)  Deferred revenue (4,571) - (4,571)  Deferred tax liabilities - - -  Total liabilities assumed $ (13,970) $ - $ (13,970)  Net assets acquired $ 801,533 $ 2,348 $ 803,881  The acquisition is considered a material business combination and accordingly unaudited pro forma information presented below for the fiscal years ended June 30, 2016 and 2015, include the effects of pro forma adjustments as if the acquisition of Brightree occurred on July 1, 2014. The pro forma results were prepared using the acquisition method of accounting and combine our historical results and Brightree’s for the fiscal years ended June 30, 2016 and 2015, including the effects of the business combination, primarily amortization expense related to the fair value of identifiable intangible assets acquired, interest expense associated with the financing obtained by us in connection with the acquisition, and the elimination of incurred acquisition-related costs.  The pro forma financial information presented below is not necessarily indicative of the results of operations that would have been achieved if the acquisition occurred at the beginning of the earliest period presented, nor is it intended to be a projection of future results.      Unaudited Proforma Consolidated Results Years Ended June 30,  (In thousands, except per share information) 2016 2015  Revenue $ 1,931,257 $ 1,780,727  Net income attributable to stockholders $ 354,565 $ 347,563  Basic earnings per share $ 2.53 $ 2.47  Diluted earnings per share $ 2.54 $ 2.44  The unaudited pro forma consolidated results for the years ended June 30, 2016, and 2015 reflect primarily the following pro forma pre-tax adjustments:  · Addition of net amortization expense related to the fair value of identifiable intangible assets acquired of $19.9 million and $26.2 million for the years ended June 30, 2016 and June 30, 2015, respectively. · Addition of net interest expense associated with debt that was issued to finance the acquisition of $16.1 million and $16.5 million for the years ended June 30, 2016 and June 30, 2015, respectively. · Elimination of pre-tax acquisition-related costs totaling $4.1 million from the results for the year ended June 30, 2016. · Addition of net income tax expense of $1.3 million for the year ended June 30, 2016 and elimination of net income tax expense of $3.1 million for the year ended June 30, 2015, respectively.  Although Brightree and its U.S. subsidiaries had historically elected to be treated as a partnership for U.S. Federal and state income tax purposes, and therefore, no income tax expense or benefit was previously recognized by Brightree in the U.S., the pro forma financial information assumes that Brightree’s historical income tax expense is based on a U.S. statutory rate of 37% . Brightree’s historical income tax expense was a benefit of $1.2 million and $0.4 million for the twelve months ended June 30, 2016 and 2015, respectively. The effective tax rate of the combined company could be significantly different depending on post-acquisition activities, such as the tax treatment applicable to each entity and the geographical mix of taxable income affecting state and foreign taxes, among other factors.  Other Acquisitions  On October 2, 2015 , we completed the acquisition of 100% of the shares in Curative Medical Technology Inc., a leading provider of non-invasive ventilation and sleep-disordered breathing medical devices and accessories in China. Curative Medical has its manufacturing base in Suzhou, China, offices in Beijing, Germany and the United States, and a distributor network throughout China and in other select markets. On November 6, 2015 , we completed the acquisition of 100% of the shares in Maribo Medico A/S, a distributor of medical equipment for treating, diagnosing, and managing sleep-disordered breathing and other respiratory disorders in Denmark and the Nordics. On November 30, 2015 , we completed the acquisition of 100% of the shares in Bennett Precision Tooling Pty Ltd, an Australian based company that designs and manufactures tools specializing in applications for Liquid Silicon Rubber. On January 29, 2016 , we completed the acquisition of 100% of the shares in Inova Labs Inc. (“Inova Labs”), a medical device company specializing in the development and commercialization of innovative oxygen therapy products. These acquisitions have been accounted for as business combinations using purchase accounting and are included in our consolidated financial statements from their respective acquisition dates. The acquisitions, individually and collectively, are not considered a material business combination and accordingly pro forma information is not provided. The acquisitions were funded through cash on-hand and by drawing on our existing credit facility.  We have completed the purchase price allocation in relation to all these acquisitions. The cost of the acquisitions was allocated to the assets acquired and liabilities assumed based on estimates of their fair values at the date of acquisition. The goodwill recognized as part of these acquisitions, which is not deductible for tax purposes, mainly represents the synergies that are unique to our combined businesses and the potential for new products and services to be developed in the future. The fair values of assets acquired and liabilities assumed, and the estimated useful lives of intangible assets acquired are as follows (in thousands):     Preliminary Adjustments Final Intangible assets - useful life  Current assets $ 49,370 3,184 52,554  Property, plant and equipment 5,294 - 5,294  Trade names 17,400 - 17,400 7 years  Non-compete 1,400 - 1,400 5 years  Developed technology 20,515 585 21,100 5 years  Customer relationships 37,303 600 37,903 5 to 8 years  Goodwill 194,216 (3,551) 190,665  Assets acquired $ 325,498 $ 818 $ 326,316  Current liabilities (21,147) (370) (21,517)  Debt assumed (21,201) - (21,201)  Deferred revenue (4,283) - (4,283)  Deferred tax liabilities (19,207) (448) (19,655)  Total liabilities assumed $ (65,838) $ (818) $ (66,656)  Net assets acquired $ 259,660 $ - $ 259,660   During the year ended June 30, 2016 , we recorded $ 5.3 million in acquisition-related expenses.

Summary Of Significant Accoun33

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Jun. 30, 2017
Summary Of Significant Accounting Policies [Abstract]
Basis Of Consolidation	Basis of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation.  The preparation of financial statements in conformity with U.S. generally accounting principles requires management estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from management’s estimates.
Revenue Recognition	Revenue Recognition We generally record revenue on product sales at the time of shipment, which is when title transfers to the customer. We do not record revenue on product sales which require customer acceptance until we receive acceptance. We initially defer service revenue received in advance from service contracts and recognize that deferred revenue ratably over the life of the service contract. We initially defer revenue we receive in advance from rental unit contracts and recognize that deferred revenue ratably over the life of the rental contract. Otherwise, we recognize revenue from rental unit contracts ratably over the life of the rental contract. We include in revenue freight charges we bill to customers. We charge all freight-related expenses to cost of sales. Taxes assessed by government authorities that are imposed on and concurrent with revenue-producing transactions, such as sales and value added taxes, are excluded from revenue.  We do not recognize revenues to the extent that we offer a right of return or other recourse with respect to the sale of our products, other than returns for product defects or other warranty claims, nor do we recognize revenues if we offer variable sale prices for subsequent events or activities. However, as part of our sales processes we may provide upfront discounts for large orders, one-time special pricing to support new product introductions, sales rebates for centralized purchasing entities or price-breaks for regular order volumes. We record the costs of all such programs as an adjustment to revenue at the time the related revenue is recognized. Our products are predominantly therapy-based equipment and require no installation. Therefore, we have no installation obligations. For multiple-element arrangements, we allocate arrangement consideration to the deliverables by use of the relative selling price method. The selling price used for each deliverable is based on vendor–specific objective evidence.  We also generate revenue from time-based licensing of our software and associated services. In most instances, revenue is generated under sales agreements with multiple elements comprising subscription fees and professional services, which typically have contract terms of one to three years. We evaluate each element in these multiple-element arrangements to determine whether they represent a separate unit of accounting and recognize each element as the services are performed. 
Cash And Cash Equivalents	Cash and Cash Equivalents Cash equivalents include certificates of deposit and other highly liquid investments and we state them at cost, which approximates market. We consider investments with original maturities of 90 days or less to be cash equivalents for purposes of the consolidated statements of cash flows.  Our cash and cash equivalents balance at June 30, 2017 , include $276.5 million in cash which is subject to notice periods of up to 90 days. The se cash balances earn interest rates above normal term deposit rates otherwise available and are held at highly rated financial institutions. 
Inventories	Inventories We state inventories at the lower of cost (determined principally by the first-in, first-out method) or net realizable value. We include material, labor and manufacturing overhead costs in finished goods and work-in-process inventories. We review and provide for any product obsolescence in our manufacturing and distribution operations by assessing throughout the year individual products and components (based on estimated future usage and sales).
Property, Plant And Equipment	Property, Plant and Equipment We record property, plant and equipment, including rental and demonstration equipment at cost. We compute depreciation expense using the straight-line method over the estimated useful lives of the assets. Useful lives are generally two to ten years except for buildings which are depreciated over an estimated useful life of 40 years and leasehold improvements, which we amortize over the lease term. We charge maintenance and repairs to expense as we incur them.
Intangible Assets	Intangible Assets We capitalize the registration costs for new patents and amortize the costs over the estimated useful life of the patent, which is generally five years. If a patent is superseded or a product is retired, any unamortized costs are written off immediately.  We amortize all of our other intangible assets on a straight-line basis over their estimated useful lives, which range from two to fifteen years. We evaluate the recoverability of intangible assets periodically and take into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists. We have not identified any impairment of intangible assets during any of the periods presented.
Goodwill	Goodwill We conducted our annual review for goodwill impairment during the final quarter of the year ended June 30, 2017 . Our goodwill impairment tests are performed at our reporting unit level which is one level below our operating segment. Fair value is determined based on estimated discounted cash flows. Our goodwill impairment review involved the following steps: Step 0 or Qualitative assessment – Evaluate qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Factors considered included, but were not limited to, macroeconomic conditions, industry and market considerations, cost factors, overall financial performance or events-specific to that reporting unit. If or when we determine it is more likely than not that the fair value of a reporting unit is less than the carrying amount, including goodwill, we would move to Step 1 of the quantitative method.  Step 1 - Compare the fair value for each reporting unit to its carrying value, including goodwill. For each reporting unit where the carrying value, including goodwill, exceeds the reporting unit’s fair value, move on to Step 2. If a reporting unit’s fair value exceeds the carrying value, no further work is performed and no impairment charge is necessary.  Step 2 - Allocate the fair value of the reporting unit to its identifiable tangible and non-goodwill intangible assets and liabilities. This will derive an implied fair value for the goodwill. Then, compare the implied fair value of the reporting unit’s goodwill with the carrying amount of the reporting unit’s goodwill. If the carrying amount of the reporting unit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess.  The results of our review indicated that no impaired goodwill exists as the fair value for each reporting unit exceeded its carrying value.
Foreign Currency	Foreign Currency The consolidated financial statements of our non-U.S. subsidiaries, whose functional currencies are other than the U.S. dollar, are translated into U.S. dollars for financial reporting purposes. We translate assets and liabilities of non-U.S. subsidiaries whose functional currencies are other than the U.S. dollar at period end exchange rates, but translate revenue and expense transactions at average exchange rates for the period. We recognize cumulative translation adjustments as part of comprehensive income, as detailed in the consolidated statements of comprehensive income, and include those adjustments in accumulated other comprehensive income in the consolidated balance sheets until such time the relevant subsidiary is sold or substantially or completely liquidated. We reflect gains and losses on transactions denominated in other than the functional currency of an entity in our results of operations. 
Research And Development	Research and Development We record all research and development expenses in the period we incur them.
Financial Instruments	Financial Instruments The carrying value of financial instruments, such as cash equivalents, accounts receivable and accounts payable, approximate their fair value because of their short-term nature. The carrying value of long-term debt approximates its fair value as the principal amounts outstanding are subject to variable interest rates that are based on market rates which are regularly reset. Foreign currency hedging instruments are marked to market and therefore reflect their fair value. We do not hold or issue financial instruments for trading purposes. The fair value of financial instruments is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
Foreign Exchange Risk Management	Foreign Exchange Risk Management We enter into various types of foreign exchange contracts in managing our foreign exchange risk, including derivative financial instruments encompassing forward exchange contracts and foreign currency options. The purpose of our foreign currency hedging activities is to protect us from adverse exchange rate fluctuations with respect to net cash movements resulting from the sales of products to foreign customers and Australian and Singapore manufacturing activities. We enter into foreign exchange contracts to hedge anticipated sales and manufacturing costs, principally denominated in Australian and Singapore dollars, and Euros. The terms of such foreign exchange contracts generally do not exceed three years. We have determined our hedge program to be a non-effective hedge as defined. We record the foreign currency derivatives portfolio at fair value and include it in other assets and accrued expenses in our consolidated balance sheets. We do not offset the fair value amounts recognized for foreign currency derivatives. We classify purchases of foreign currency derivatives and proceeds received from the exercise of foreign currency derivatives as an investing activity within our consolidated statements of cash flows. We record all movements in the fair value of the foreign currency derivatives within other income, net in our consolidated statements of income.
Income Taxes	Income Taxes We account for income taxes under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using the enacted tax rates we expect to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
Provision For Warranty	Provision for Warranty We provide for the estimated cost of product warranties at the time the related revenue is recognized. We determine the amount of this provision by using a financial model, which takes into consideration actual historical expenses and potential risks associated with our different products. We use this financial model to calculate the future probable expenses related to warranty and the required level of the warranty provision. Although we engage in product improvement programs and processes, our warranty obligation is affected by product failure rates and costs incurred to correct those product failures. Should actual product failure rates or estimated costs to repair those product failures differ from our estimates, we would be required to revise our estimated warranty provision.
Allowance For Doubtful Accounts	Allowance for Doubtful Accounts We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments, which results in bad debt expense. We determine the adequacy of this allowance by periodically evaluating individual customer receivables, considering a customer’s financial condition, credit history and current economic conditions. We are also contingently liable, within certain limits, in the event of a customer default, to independent leasing companies in connection with customer leasing programs. We monitor the collection status of these installment receivables and provide for estimated losses separately under accrued expenses within our consolidated balance sheets based upon our historical collection experience with such receivables and a current assessment of our credit exposure. 
Impairment Of Long-Lived Assets	Impairment of Long-Lived Assets We periodically evaluate the carrying value of long-lived assets to be held and used, including certain identifiable intangible assets, when events and circumstances indicate that the carrying amount of an asset may not be recovered. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If assets are considered to be impaired, we recognize as the impairment the amount by which the carrying amount of the assets exceeds the fair value of the assets. We report assets to be disposed of at the lower of the carrying amount or fair value less costs to sell.  We did not recognize impairment charges in relation to long-lived assets during the fiscal years ended June 30, 2017 and 2015, but during the fiscal year ended June 30, 2016 , we recognized $ 2.8 million of impairment charges.
Contingencies	Contingencies  We record a liability in the consolidated financial statements for loss contingencies when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. When determining the estimated loss or range of loss, significant judgment is required to estimate the amount and timing of a loss to be recorded.
