Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | 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 intercompany transactions and balances have been eliminated in consolidation. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Certain prior period amounts have been reclassified to conform to the current period presentation. Actual results could differ from management’s estimates. (b)Revenue Recognition In accordance with Accounting Standard Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers”, we account for a contract with a customer when there is a legally enforceable contract, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. We have determined that we have two operating segments, which are the sleep and respiratory disorders sector of the medical device industry (“Sleep and Respiratory Care”) and the supply of business management software as a service to out-of-hospital care providers (“SaaS”). Our Sleep and Respiratory Care revenue relates primarily to the sale of our products that are therapy-based equipment. Some contracts include additional performance obligations such as the provision of extended warranties and provision of data for patient monitoring. Our SaaS revenue relates to the provision of software access with ongoing support and maintenance services as well as professional services such as training and consulting. Disaggregation of revenue See Note 13 – Segment Information for our net revenue disaggregated by segment, product and region for the years ended June 30, 2023, 2022 and 2021. Performance obligations and contract balances Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied; generally, this occurs with the transfer of risk and/or control of our products at a point in time. For products in our Sleep and Respiratory Care business, we transfer control and recognize a sale when products are shipped to the customer in accordance with the contractual shipping terms. For our SaaS business, revenue associated with cloud-hosted services are recognized as they are provided. We defer the recognition of a portion of the consideration received when performance obligations are not yet satisfied. Consideration received from customers in advance of revenue recognition is classified as deferred revenue. Performance obligations resulting in deferred revenue in our Sleep and Respiratory Care business relate primarily to extended warranties on our devices and the provision of data for patient monitoring. Performance obligations resulting in deferred revenue in our SaaS business relate primarily to the provision of software access with maintenance and support over an agreed term and material rights associated with future discounts upon renewal of some SaaS contracts. Generally, deferred revenue will be recognized over a period of one year to five years. Our contracts do not contain significant financing components. The following table summarizes our contract balances as of June 30, 2023 and 2022 (in thousands):

Transaction price determination Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. In our Sleep and Respiratory Care segment, the amount of consideration received and revenue recognized varies with changes in marketing incentives (e.g. rebates, discounts, free goods) and returns offered to our customers and their customers. When we give customers the right to return eligible products and receive credit, returns are estimated based on an analysis of our historical experience. However, returns of products, excluding warranty-related returns, have historically been infrequent and insignificant. We adjust the estimate of revenue at the earlier of when the most likely amount of consideration can be estimated, the amount expected to be received changes, or when the consideration becomes fixed. We offer our Sleep and Respiratory Care customers cash or product rebates based on volume or sales targets measured over quarterly or annual periods. We estimate rebates based on each customer’s expected achievement of its targets. In accounting for these rebate programs, we reduce revenue ratably as sales occur over the rebate period by the expected value of the rebates to be returned to the customer. Rebates measured over a quarterly period are updated based on actual sales results and, therefore, no estimation is required to determine the reduction to revenue. For rebates measured over annual periods, we update our estimates each quarter based on actual sales results and updated forecasts for the remaining rebate periods. We participate in programs where we issue credits to our Sleep and Respiratory Care distributors when they are required to sell our products below negotiated list prices if we have preexisting contracts with the distributors' customers. We reduce revenue for future credits at the time of sale to the distributor, which we estimate based on historical experience using the expected value method. We also offer discounts to both our Sleep and Respiratory Care as well as our SaaS customers as part of normal business practice and these are deducted from revenue when the sale occurs. When Sleep and Respiratory Care or SaaS contracts have multiple performance obligations, we generally use an observable price to determine the stand-alone selling price by reference to pricing and discounting practices for the specific product or service when sold separately to similar customers. Revenue is then allocated proportionately, based on the determined stand-alone selling price, to each performance obligation. An allocation is not required for many of our Sleep and Respiratory Care contracts that have a single performance obligation, which is the shipment of our therapy-based equipment. Accounting and practical expedient elections We have elected to account for shipping and handling activities associated with our Sleep and Respiratory Care segment as a fulfillment cost within cost of sales, and record shipping and handling costs collected from customers in net revenue. We have also elected for all taxes assessed by government authorities that are imposed on and concurrent with revenue-producing transactions, such as sales and value added taxes, to be excluded from revenue and presented on a net basis. We have adopted two practical expedients including the “right to invoice” practical expedient, which allows us to recognize revenue in the amount of the invoice when it corresponds directly with the value of performance completed to date and which is relevant for some of our SaaS contracts. The second practical expedient adopted permits relief from considering a significant financing component when the payment for the good or service is expected to be one year or less. (c)Concentration of Credit Risk and Significant Customers Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, derivatives and trade receivables. Our cash and cash equivalents are generally held with large, diverse financial institutions to reduce the amount of exposure to any single financial institution. Our derivative contracts are transacted with various financial institutions with high credit standings and any exposure to counterparty credit-related losses in these contracts is largely mitigated with collateralization and master-netting agreements. The risk with respect to trade receivables is mitigated by credit evaluations we perform on our customers, the short duration of our payment terms for the significant majority of our customer contracts and by the diversification of our customer base. No single customer accounted for 10% or more of our total revenues for any of the periods presented. (d) Fair Value of Financial Instruments 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. We measure our financial instruments at fair value at each reporting period using a fair value hierarchy that requires that we maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value: Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Other inputs that are directly or indirectly observable in the marketplace. Level 3 - Unobservable inputs that are supported by little or no market activity. The carrying value of cash equivalents, accounts receivable and accounts payable, approximate their fair value because of their short-term nature. The carrying value of long-term debt related to our Revolving Credit and Term Credit Agreements 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. The carrying value of long-term debt related to our Senior Notes can differ to its fair value as the principal amounts outstanding are subject to fixed interest rates as outlined in Note 8 - Debt. Foreign currency hedging instruments are marked to market and therefore reflect their fair value. In addition, we measure investments in publicly held equity securities and privately held equity securities for which there has been an observable price change in an identical or similar security, at fair value. We do not hold or issue financial instruments for trading purposes. (e)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. (f)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). (g)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 years to ten years except for buildings which are depreciated over an estimated useful life of forty years and leasehold improvements, which we amortize over the shorter of the useful life or the lease term. We charge maintenance and repairs to expense as we incur them. Depreciation expense for property, plant, and equipment was $84.7 million, $81.0 million, and $78.4 million for the years ended June 30, 2023, 2022 and 2021, respectively. (h)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 ten 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 years to fifteen years. We take into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists and, at least annually, evaluate the recoverability of intangible assets. We have not identified any impairment of intangible assets during any of the periods presented. (i)Goodwill We conduct our annual review for goodwill impairment during the final quarter of the fiscal year. Our goodwill impairment review is performed at our reporting unit level, which is one level below our operating segments and involves 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. The factors we consider include, but are 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. Fair value is determined based on estimated discounted cash flows. A goodwill impairment charge is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. If a reporting unit’s fair value exceeds the carrying value, no further work is performed and no impairment charge is necessary. During the annual reviews for the years ended June 30, 2023, 2022 and 2021, we completed a Step 0 or Qualitative assessment and determined it was more likely than not that the fair value of our reporting units exceeded their carrying amounts, including goodwill, and therefore goodwill was not impaired. (j)Equity investments We have equity investments in privately and publicly held companies that are unconsolidated entities. The following discusses our accounting for investments in marketable equity securities, non-marketable equity securities, and investments accounted for under the equity method. Our marketable equity securities are publicly traded stocks measured at fair value and classified within Level 1 in the fair value hierarchy because we use quoted prices for identical assets in active markets. Marketable equity securities are recorded in prepaid expenses and other current assets on the consolidated balance sheets. Non-marketable equity securities consist of investments in privately held companies without readily determinable fair values and are recorded in prepaid taxes and other non-current assets on the consolidated balance sheets. Non-marketable equity securities are reported at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. We assess non-marketable equity securities at least quarterly for impairment and consider qualitative and quantitative factors including the investee's financial metrics, product and commercial outlook and cash usage. All gains and losses on marketable and non-marketable equity securities, realized and unrealized, are recognized in gain (loss) on equity investments as a component of other income (loss), net on the consolidated statements of income. Equity investments whereby we have significant influence but not control over the investee and are not the primary beneficiary of the investee’s activities, are accounted for under the equity method. Under this method, we record our share of gains or losses attributable to equity method investments as a component of other income (loss), net on the consolidated statements of income. (k)Research and Development We record all research and development expenses in the period we incur them. (l)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. (m)Foreign Exchange Risk Management We may use derivative financial instruments, specifically foreign cross-currency swaps, purchased foreign currency call options, collars and forward contracts to mitigate exposure from certain foreign currency risk. No derivatives are used for trading or speculative purposes. We do not require or are not required to pledge collateral for the derivative instruments. Fair Value and Net Investment Hedging On November 17, 2022, we executed foreign cross-currency swaps as net investment hedges and fair value hedges in designated hedging relationships with either the foreign denominated net asset balances or the foreign denominated intercompany loan as the hedged items. All derivatives are recorded at fair value as either an asset or liability. Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the hedged item. The purpose of the cross-currency swaps for the fair value hedge is to mitigate foreign currency risk associated with changes in spot rates on foreign denominated intercompany debt between USD and EUR. For these hedges, we excluded certain components from the assessment of hedge effectiveness that are not related to spot rates. For fair value hedges that qualify and are designated for hedge accounting, the change in fair value of the derivative is recorded in the same line item as the hedged item, other, net, in the consolidated statement of income. The initial fair value of hedge components excluded from the assessment of effectiveness is recognized in the statement of income under a systematic and rational method over the life of the hedging instrument and is presented in interest (expense) income, net. Any difference between the change in the fair value of the hedge components excluded from the assessment of effectiveness and the amounts recognized in earnings is recorded as a component of other comprehensive income. The purpose of the cross-currency swaps for the net investment hedge is to mitigate foreign currency risk associated with changes in spot rates on the net asset balances of our foreign functional subsidiaries. For net investment hedges that qualify and are designated for hedge accounting, the change in fair value of the derivative is recorded in cumulative translation adjustment within other comprehensive loss and reclassified into earnings when the hedged net investment is either sold or substantially liquidated. The initial fair value of components excluded from the assessment of hedge effectiveness will be recognized in interest (expense) income, net. The notional value of outstanding foreign cross-currency swaps was $1,046.6 million at June 30, 2023. These contracts mature at various dates prior to December 31, 2029. Non-Designated Hedges We transact business in various foreign currencies, including a number of major European currencies as well as the Australian and Singapore dollars. We have foreign currency exposure through both our Australian and Singapore manufacturing activities, and international sales operations. We have established a foreign currency hedging program using purchased foreign currency call options, collars 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 two years. The purpose of this hedging program is to economically manage the financial impact of foreign currency exposures denominated mainly in Euros, and 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. All movements in the fair value of the foreign currency instruments are recorded within other, net in our consolidated statements of income. The notional value of the outstanding non-designated hedges was $954.7 million and $602.0 million at June 30, 2023 and June 30, 2022, respectively. These contracts mature at various dates prior to December 15, 2024. We classified the fair values of all hedging instruments as Level 2 measurements within the fair value hierarchy. We are exposed to credit-related losses in the event of non-performance by counter parties to financial instruments. We minimize counterparty credit risk by entering into derivative transactions with major financial institutions and we do not expect material losses as a result of default by our counterparties. (n)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. We recognize the impact of a tax position in the consolidated financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions are reflected in income tax expense. (o)Provision for Warranty We provide for the estimated cost of product warranties on our Sleep and Respiratory Care products 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. (p)Allowance for Credit Losses We maintain an allowance for credit losses on customer receivables based on our historical write-off experience, an assessment of our customers’ financial conditions and available information that is relevant to assessing the collectability of cash flows, which includes current conditions and forecasts about future economic conditions. Customer receivables are charged against the allowance when they are deemed uncollectible. We are also contingently liable, within certain limits, in the event of a customer default, to independent financing companies in connection with customer financing 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. (q)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, 2023, 2022 and 2021. (r)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.
