ResMed Inc. (referred to herein as “we”, “us”, “our” or the “Company”) is a Delaware corporation formed in March 1994 as a holding company for the ResMed Group. Through our subsidiaries, we design, manufacture and market equipment for the diagnosis and treatment of sleep-disordered breathing and other respiratory disorders, including obstructive sleep apnea. Our manufacturing operations are located in Australia, Singapore, France, Germany and the United States. Major distribution and sales sites are located in the United States, Germany, France, the United Kingdom, Switzerland, Australia, Norway and Sweden.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three months ended September 30, 2011 are not necessarily indicative of the results that may be expected for the year ending June 30, 2012.

The condensed consolidated financial statements for the three months ended September 30, 2011 and 2010 are unaudited and should be read in conjunction with the consolidated financial statements and notes thereto included in our Form 10-K for the year ended June 30, 2011.

The condensed 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 accounting principles generally accepted in the United States requires management estimates and assumptions that affect amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from management’s estimates.

We generally record revenue on product sales at the time of shipment, when title transfers to the customer. We do not record revenue on product sales which require customer acceptance until we receive acceptance. We record royalty revenue from license agreements when earned. 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 initially defer revenue from sale of marketing and distribution rights and recognize that deferred revenue ratably over the life of the 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. Our products are predominantly therapy-based equipment and require no installation. Therefore, we have no significant installation obligations.

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 condensed consolidated financial statements.

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).

We record property, plant and equipment, including rental 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 forty years and leasehold improvements, which we amortize over the lease term. We charge maintenance and repairs to expense as we incur them.

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 product that is retired, any unamortized costs are written off immediately.

We amortize other intangible assets on a straight-line basis over their estimated useful lives, which range from two to nine 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 amortize all of our intangible assets. We have not identified any impairment of intangible assets during any of the periods presented.

We conducted our annual review for goodwill impairment during the final quarter of fiscal 2011. In conducting our review of goodwill impairment, we identified 10 reporting units, being components of our operating segment. The fair value for each reporting unit was determined based on estimated discounted cash flows. Our goodwill impairment review involved the following process:

The results of Step 1 of our annual review indicated that no impaired goodwill exists as the fair value for each reporting unit significantly exceeded its carrying value.

The consolidated financial statements of our non-U.S. subsidiaries, whose functional currencies are other than U.S. dollars, 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 Note 4, and included those adjustments in accumulated other comprehensive income in the condensed consolidated balance sheets until 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.

All research and development costs are expensed in the period incurred.

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 930,468 and 182,459 for the three months ended September 30, 2011 and 2010, respectively, as the effect would have been anti-dilutive. Basic and diluted earnings per share for the three months ended September 30, 2011 and 2010 are calculated as follows (in thousands except per share data):

The carrying value of financial instruments, such as cash and 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 option contracts 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.

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 our Australian manufacturing activities. We enter into foreign currency option contracts to hedge anticipated sales and manufacturing costs, principally denominated in Australian dollars and Euros. The terms of such foreign currency option contracts generally do not exceed three years.

We have determined our hedge program to be a non-effective hedge as defined under the FASB issued authoritative guidance. We record the foreign currency derivatives portfolio at fair value and include it in other assets in our condensed 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 condensed consolidated statements of income.

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.

Management determines the appropriate classification of our investments in debt and equity securities at the time of purchase and re-evaluates such determination at each balance sheet date. We classify as available-for-sale debt securities for which we do not intend, or are not able to hold to maturity. We carry securities available-for-sale at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income.

Estimated future warranty costs related to certain products are charged to operations in the period in which the related revenue is recognized. We include the liability for warranty costs in accrued expenses in our condensed consolidated balance sheets. Changes in the liability for warranty costs for the three months ended September 30, 2011 and 2010 are as follows (in thousands):

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. During the three months ended September 30, 2011 and 2010, we recognized an impairment charge of $Nil and $2.3 million, respectively, relating to impaired long-lived assets that were no longer in use.

The aggregate carrying amount of our cost-method investments at September 30, 2011 and June 30, 2011, was $3.1 million and $4.3 million, respectively. During the three months ended September 30, 2011 we remeasured a previously held equity interest to its acquisition-date fair value as a result of acquiring the remaining interest as part of a business combination and recognized a resulting gain of $2.1 million in Other Income in the condensed consolidated statement of income. See Note 13 for additional information. 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 have determined that the carrying value of our cost method investments do not exceed their estimated fair values.

We have granted stock options and restricted stock units to personnel, including officers and directors, under the ResMed Inc. 2009 Incentive Award Plan (the “2009 Plan”), the 2006 Incentive Award Plan, as amended and the Amended and Restated ResMed Inc. 2006 Incentive Award Plan. These options and restricted stock units expire seven years after the grant date and vest over one or four years. We granted the options with the exercise prices equal to the market value as determined at the date of grant. We have also offered to our personnel, including officers, the right to purchase shares of our common stock at a discount under the ResMed Inc. 2009 Employee Stock Purchase Plan (the “ESPP”).

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 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. 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 assuming no dividends and using the following assumptions:

The risk-free interest rate assumption we use is based upon U.S. Treasury yield curve at the time of grant appropriate for the expected life of the awards. Expected volatilities are based on a combination of historical volatilities of our stock and the implied volatilities from tradeable options of our stock corresponding to the expected term of the options. We use a combination of the historic and implied volatilities as the addition of the implied volatility is more representative of our future stock price trends. While there is a tradeable market of options on our common stock less emphasis is placed on the implied volatility of these options due to the relative low volumes of these traded options and the difference in the terms compared to our employee options. In order to determine the estimated period of time that we expect employees to hold their stock options, we use historical rates by employee groups.

In September 2011, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. Under the amendments in this standard, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We will be required to adopt this standard for interim and annual reporting periods beginning after December 15, 2011. We do not expect the adoption of this standard in fiscal year 2012 to have a material impact on our condensed consolidated financial statements.

In June 2011, the FASB issued authoritative guidance with respect to the presentation of other comprehensive income in financial statements. The main provisions of the standard provide that an entity that reports other comprehensive income has the option to present comprehensive income in either a single statement or in a two-statement approach. A single statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income. In the two-statement approach, an entity must present the components of net income and total net income in the first statement, followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income. We will be required to adopt this standard for interim and annual reporting periods beginning after December 15, 2011. We do not expect the adoption of this standard in fiscal year 2012 to have a material impact on our condensed consolidated financial statements.

Inventories were comprised of the following at September 30, 2011 and June 30, 2011 (in thousands):

Accumulated other comprehensive income was comprised of foreign currency translation gains of $200.2 million at September 30, 2011 and $324.4 million at June 30, 2011.

We do not provide for U.S. income taxes on foreign currency translation adjustments since we do not provide for such taxes on undistributed earnings of foreign subsidiaries.

Property, plant and equipment were comprised of the following as of September 30, 2011 and June 30, 2011 (in thousands):

Long-term debt at September 30, 2011, and June 30, 2011 consists of the following (in thousands):

Credit Facility

On February 10, 2011, we entered into a credit agreement with lenders, including Union Bank, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, HSBC Bank USA, National Association, as Syndication Agent and Union Bank, N.A., HSBC Bank USA, National Association, Commonwealth Bank of Australia and Wells Fargo Bank, N.A. The credit agreement provides a $300 million three-year revolving credit facility, with an uncommitted option to increase the credit facility by an additional $100 million. The credit facility also includes a $10 million sublimit for letters of credit. The credit facility terminates on February 10, 2014, at which time 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, at our option, either (i) LIBOR plus 1.5% to 2.0% (depending on the applicable leverage ratio) or (ii) a base rate, as defined in the Credit Agreement, plus 0.5% to 1.0% (depending on the applicable leverage ratio). Commitment fees of 0.25% to 0.375% (depending on the applicable leverage ratio) apply on the unused portion of the credit facility. When we executed the credit agreement, we used a portion of the credit facility to repay the outstanding balance under our previously existing revolving credit facility with Union Bank, N.A., which was then terminated.

Our obligations under the credit agreement are secured by (a) the corporate stock we hold in our subsidiaries ResMed Corp., ResMed Motor Technologies Inc. (“ResMed Motor”) and ResMed Assembly US Inc., (“ResMed US”), and (b) up to 65% of the ownership interests we hold in our subsidiary ResMed EAP Holdings LLC (“ResMed EAP”). Our obligations under the credit agreement are also guaranteed by our subsidiaries ResMed Corp, ResMed US and ResMed Motor. The credit agreement contains customary covenants, including certain financial covenants and an obligation that we maintain certain financial ratios, including a maximum ratio of Funded Debt to EBITDA (each as defined in the credit agreement), an interest coverage ratio and a maximum amount of annual capital expenditures. The entire principal amount of the credit facility and any accrued but unpaid interest may be declared immediately due and payable if an event of default occurs. Events of default include failure to make payments when due, a default in the performance of any covenants in the credit agreement or related documents or certain changes of control of us or our subsidiaries ResMed Corp., ResMed US, ResMed Motor, ResMed Limited, ResMed Holdings Ltd/LLC or ResMed EAP.

At September 30, 2011 we were in compliance with our debt covenants and there was $130.0 million outstanding under the credit agreement.

Prepayment Facility

During the year ended June 30, 2010, ResMed EPN Limited, our wholly-owned UK subsidiary, obtained access to a Prepayment Facility with HSBC Invoice Finance (UK) Limited that provides for a cash advance facility up to a total commitment of 5 million British Pounds Sterling. These advances are limited to 75% of secured outstanding sales invoices. At September 30, 2011, there were no amounts outstanding under this facility.

Assumed External Debt

As part of our acquisition of 100% of the shares of Gruendler GmbH on August 1, 2011, detailed in Note 13, we assumed debt of 4.7 million Euros. The debt comprises a number of loan agreements of varying terms with financial institutions and venture capital financiers. We repaid 1.8 million Euros during the three months ended September 30, 2011 and expect to settle the remaining outstanding loans within the next twelve months. Accordingly, all these loans have been treated as current liabilities in our condensed consolidated balance sheets. At September 30, 2011, there was 2.9 million Euros outstanding in respect of these loans.

Common Stock. On August 24, 2011, our board of directors approved a new share repurchase program, authorizing us to acquire up to an aggregate of 20.0 million shares of ResMed Inc. 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. This program canceled and replaced our previous share repurchase program authorized on May 27, 2009 pursuant to which we had repurchased 9,952,274 shares. These were in addition to the 6,622,907 shares repurchased under an earlier program authorized on June 6, 2002. The new program authorizes us to purchase in addition to the shares we repurchased under our previous programs. There is no expiration date for this program. All share repurchases since August 24, 2011 have been executed in accordance with this program.

During the three months ended September 30, 2011, we repurchased 4.4 million shares at a cost of $124.7 million. At September 30, 2011, we have repurchased a total of 18.5 million shares at a cost of $629.3 million. 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 September 30, 2011, 18.1 million additional shares can be repurchased under the approved share repurchase program.

Preferred Stock. In April 1997, the Board of Directors authorized 2,000,000 shares of $0.01 par value preferred stock. No such shares were issued or outstanding at September 30, 2011 and June 30, 2011.

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 2009 Plan. These options and restricted stock units have expiration dates of seven years from the date of grant and vest over one or four years. 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 22,921,650. The number of securities remaining available for future issuance under the 2009 Plan at September 30, 2011 is 5,351,788. The number of shares of our common stock available for issuance under the 2009 Plan will be reduced by (i) two (2.0) 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 3,000,000 shares of our common stock (except in a participant’s initial year of hiring up to 4,500,000 shares of our common stock may be granted).

At September 30, 2011, there was $53.9 million in unrecognized compensation costs related to unvested stock-based compensation arrangements. This is expected to be recognized over a weighted average period of 2.7 years. The aggregate intrinsic value of the stock-based compensation arrangements outstanding and exercisable at September 30, 2011 was $163.3 million and $78.6 million, respectively. The aggregate intrinsic value of the options exercised during the three months ended September 30, 2011 and 2010, was $5.6 million and $11.6 million, respectively.

Employee Stock Purchase Plan (the “ESPP”). The ESPP was approved at the annual meeting of our stockholders on November 18, 2009, as an amendment to the previously approved employee stock purchase plan. 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 September 30, 2011, the number of shares remaining available for future issuance under the ESPP is 775,000.

During the three months ended September 30, 2011, we recognized $0.5 million of stock-based compensation expense associated with the ESPP.

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:

The following table summarizes our financial assets and liabilities, as at September 30, 2011, using the valuation input hierarchy (in thousands):

We determine the fair value of our financial assets as follows:

Cash and cash equivalents – The valuation used for our cash and other money market funds are derived from quoted market prices due to their short term nature and there is an active market for these financial instruments.

Cost-method investments – These investments include our holdings in privately held service companies 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.

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.

The following table shows a reconciliation of the changes in the three months ended September 30, 2011 for fair value measurements using significant unobservable inputs (thousands):

We did not have any significant non-financial assets or liabilities measured at fair value on September 30, 2011 or June 30, 2011.

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 condensed consolidated financial statements taken as a whole.

During September and October 2004, we began receiving tax assessment notices for the audit of one of our German subsidiaries by the German tax authorities for the years 1996 through 1998. Certain aspects of these assessment notices are being contested in German tax court. As the outcome of these proceedings cannot be predicted with certainty, any tax issues resolved in a manner not consistent with our expectations may require us to adjust our provision for income tax in the period of resolution. However, the estimate of the range of loss or possible loss in relation to the tax assessment notices for the years which are being contested is immaterial to our condensed consolidated financial statements when taken as a whole.

In February 2007, the University of Sydney commenced legal action in the Federal Court of Australia against us, claiming breach of a license agreement and infringement of certain intellectual property. The claim has been amended to include an allegation of breach of confidentiality. The university is seeking various types of relief, including an injunction against manufacturing, supplying, offering for sale, selling or exporting certain mask devices, payment of license fees, damages or an account of profits, interest, costs and declaration of a constructive trust over and assignment of certain intellectual property. In October 2007, we filed a defense denying the university’s claim, as well as a cross-claim against the university seeking an order for rectification of the contract and alleging the university violated the Australian Trade Practices Act. The matter is ongoing. Given the inherent uncertainty and unpredictability of litigation and due to the status of this legal action, no range of loss or possible loss can be reasonably estimated at this time. However, we do not expect the outcome of this matter to have a material adverse effect on our condensed consolidated financial statements when taken as a whole.

In March 2011, SMRT LLC filed suit against us in California Superior Court. SMRT is a former customer of ours, and the complaint alleges various claims arising out of our decision to stop selling product to SMRT. The complaint alleges claims for violation of state anti-trust and unfair competition laws, as well as various tortious interference claims. We filed a demurrer to the complaint, which the court granted in part and denied in part. SMRT later filed an amended complaint, alleging substantially the same claims. On October 17 we filed our answer, as well as a cross-complaint to collect outstanding accounts receivable. The matter is ongoing. Given the inherent uncertainty and unpredictability of litigation and due to the status of this legal action, no range of loss or possible loss can be reasonably estimated at this time. However, we do not expect the outcome of this matter to have a material adverse effect on our condensed consolidated financial statements when taken as a whole.

Litigation, Continued

In June 2011, Geltight Enterprises, LLC filed a complaint for patent infringement against us in the United States District Court Western District of Washington at Seattle. This Complaint alleges that we infringe Geltight’s United States patent related to gel mask technology. On October 14, 2011, the court dismissed Geltight’s claims against ResMed, with prejudice, with each side to bear its own costs. We do not expect the resolution of this matter to have a material adverse effect on our condensed consolidated financial statements when taken as a whole.

Contingent Obligations Under Recourse Provisions

We use independent leasing companies for the purpose of providing finance to certain customers for the purchase of our products. In some cases, we are contingently liable to the leasing companies in the event of a customer default, within certain limits, for unpaid installment receivables transferred to the leasing companies. The gross amount of receivables sold under these arrangements for the three months ended September 30, 2011 amounted to $3.2 million. The maximum potential amount of contingent liability under these arrangements at September 30, 2011 was $5.0 million. The recourse liability we recognized at September 30, 2011, in relation to these arrangements was $0.6 million.

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 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 other income, net in our consolidated statements of income. We do not enter into financial instruments for trading or speculative purposes.

We held foreign currency instruments with notional amounts totaling $433.0 million and $309.9 million at September 30, 2011 and June 30, 2011, respectively, to hedge foreign currency fluctuations. These contracts mature at various dates prior to September 30, 2014.

The fair value and effect of derivative instruments on our consolidated financial statements were as follows:

We are exposed to credit-related losses in the event of non-performance by counter parties to financial instruments. The credit exposure of foreign currency derivatives at September 30, 2011 and June 30, 2011 was $4.8 million and $14.8 million, respectively, which represents the positive fair value of our foreign currency derivatives. These values are included in the current and non-current balances of other assets on the condensed consolidated balance sheets. We minimize counterparty credit risk by entering into derivative transactions with major financial institutions and, as such, we do not expect material losses as a result of default by our counterparties.

On July 5, 2011 we acquired the remaining 87% of the outstanding shares of BiancaMed Ltd. (“BiancaMed”), an Irish medical technology company, that has developed and is marketing a convenient, non-contact device to monitor sleep and breathing in the home and hospital. We previously held 13% of the outstanding shares of BiancaMed which was recorded within cost-method investments. In conjunction with the acquisition of BiancaMed we re-measured the previously held equity interest to its acquisition-date fair value of $4.3 million based on the difference between the fair value of 100% of BiancaMed’s shares less the fair value of the consideration transferred, excluding any control premium. As a result we recognized a gain of $2.1 million in Other Income during the three months ended September 30, 2011. The acquisition has been accounted for as a business combination using purchase accounting and is included in our consolidated financial statements from July 5, 2011. The acquisition is not considered a material business combination and was funded through cash on-hand. We have not incurred any material acquisition related costs.

On August 1, 2011 we acquired 100% of the outstanding shares of Gruendler GmbH, a developer and manufacturer of medical humidification products. These humidifiers can be used with a wide range of ventilators, from neonatal and pediatric, to non-invasive pressure support, to those used in the intensive care unit. Under the purchase agreement, we may also be required to make additional future payments of up to 5.5 million Euros based on the achievement of certain performance milestones following the acquisition. The acquisition has been accounted for as a business combination using purchase accounting and is included in our consolidated financial statements from August 1, 2011. The acquisition is not considered a material business combination and was funded through cash on-hand. We have not incurred any material acquisition related costs.

The cost of the acquisitions have been allocated to the assets acquired and liabilities assumed based on estimates of their respective fair values at the date of acquisition. We have not yet completed the purchase price allocation, as certain income tax related matters and the appraisals associated with the valuation of certain intangible assets are not yet complete. We do not believe that the completion of this work will materially modify the preliminary purchase price allocation. We expect to complete our purchase price allocation in the quarter ending December 31, 2011. The goodwill recognized as part of these acquisitions 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 following table summarizes the aggregated preliminary purchase price allocation of the assets acquired and liabilities assumed at the date of acquisitions based on an independent appraisal and internal studies (in thousands):

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

The following is an overview of our results of operations for the three months ended September 30, 2011. Management’s discussion and analysis (“MD&A”) of financial condition and results of operations is intended to help the reader understand the results of operations and financial condition of ResMed Inc. MD&A is provided as a supplement to, and should be read in conjunction with condensed consolidated financial statements and notes, included in this report.

We are a leading developer, manufacturer and distributor of medical equipment for treating, diagnosing, and managing sleep-disordered breathing (“SDB”) and other respiratory disorders. During the three months ended September 30, 2011, we continued our efforts to build awareness of the consequences of untreated SDB, and to grow our business in this market. In our efforts, we have attempted to raise awareness through market and clinical initiatives highlighting the relationship between sleep-disordered breathing/obstructive sleep apnea and co-morbidities, such as cardiac disease, diabetes, hypertension and obesity, as well as the dangers of sleep apnea in regard to occupational health and safety, especially in the transportation industry.

We are committed to ongoing investment in research and development and product enhancements. During the three months ended September 30, 2011, we invested $26.2 million on research and development activities. Since the development of continuous positive airway pressure (“CPAP”) therapy, we have developed a number of innovative products for SDB and other respiratory disorders including airflow generators, diagnostic products, mask systems, headgear and other accessories. Our new product release schedule remains active across both our mask and flow generator categories. We have recently introduced the Stellar™ ventilation device, the S9 VPAP™ series of bilevel devices, the Mirage™ FX mask and the Quattro™ FX mask. We are taking steps to increase awareness of the health dangers of sleep-disordered breathing by sponsoring educational programs targeted at the primary care physician community. We believe these efforts should further increase awareness of both doctors and patients about the relationship between sleep-disordered breathing, obstructive sleep apnea and co-morbidities such as cardiac disease, diabetes, hypertension and obesity. We believe these efforts should also support our efforts to inform the community of the dangers of sleep apnea in occupational health and safety, especially in the transport industry.

During the three months ended September 30, 2011, our net revenue increased by 12% when compared to the three months ended September 30, 2010. Gross margin was 58.8% for the three months ended September 30, 2011 compared to 61.7% for the three months ended September 30, 2010. Diluted earnings per share for the three months ended September 30, 2011 was $0.33 per share, compared to $0.36 per share for the three months ended September 30, 2010.

At September 30, 2011 our cash and cash equivalents totaled $610.1 million, our total assets were $1.9 billion and our stockholders’ equity was $1.5 billion.

In order to provide a framework for assessing how our underlying businesses performed excluding the effect of foreign currency fluctuations, we provide certain financial information on a “constant currency basis”, which is in addition to the actual financial information presented. In order to calculate our constant currency information, we translate the current period financial information using the foreign currency exchange rates that were in effect during the previous comparable period. However, constant currency measures should not be considered in isolation or as an alternative to U.S. dollars measures that reflect current period exchange rates, or to other financial measures calculated and presented in accordance with U.S. GAAP.

Net Revenue

Net revenue increased for the three months ended September 30, 2011 to $314.8 million compared to $282.0 million for the three months ended September 30, 2010, an increase of $32.8 million or 12%. The increase in net revenue is primarily attributable to the strong growth in our masks and accessories sales. Movements in international currencies against the U.S. dollar positively impacted revenues by approximately $10.6 million during the three months ended September 30, 2011. Excluding the impact of favorable foreign currency movements, net revenue for the three months ended September 30, 2011 increased by 8% compared to the three months ended September 30, 2010.

Net revenue in North and Latin America increased for the three months ended September 30, 2011 to $169.3 million from $155.6 million for the three months ended September 30, 2010, an increase of 9%. We believe this increase predominantly reflects growth in the overall sleep-disordered breathing market and growth generated from our recent product releases including the S9 bilevel flow generators and the Quattro FX and Mirage FX masks. Net international revenue, which includes all markets outside North and Latin America, for the three months ended September 30, 2011, increased to $145.5 million from $126.4 million for the three months ended September 30, 2010, an increase of 15%. Excluding the impact of movements in international currencies, international sales grew by 7% compared to the three months ended September 30, 2010. We believe this increase in sales outside North and Latin America predominantly reflects growth in the overall sleep-disordered breathing market and growth generated from our recent product releases including the S9 bilevel flow generators and the Quattro FX and Mirage FX masks.

Net revenue from the sales of flow generators, including humidifiers, for the three months ended September 30, 2011 totaled $171.0 million, an increase of 6% compared to the three months ended September 30, 2010 of $161.8 million, including decreases of 2% in North and Latin America and increases of 12% internationally. Net revenue from the sales of masks and other accessories for the three months ended September 30, 2011 totaled $143.8 million, an increase of 20% compared to the three months ended September 30, 2010 of $120.2 million, including increases of 19% in North and Latin America and 21% internationally. Excluding the impact of favorable currency movements, international revenue increased by 5% and 12% for flow generators and masks and other accessories, respectively, for the three months ended September 30, 2011 compared to the three months ended September 30, 2010. Except for the decrease in sales of flow generators in North and Latin America, which were mainly due to the decline in our CPAP flow generator sales, we believe the increases primarily reflect growth in the overall sleep-disordered breathing market and contributions from new products.

The following table summarizes the percentage movements in our net revenue for the three months ended September 30, 2011 compared to the three months ended September 30, 2010:

Gross Profit

Gross profit increased for the three months ended September 30, 2011 to $185.1 million from $174.0 million for the three months ended September 30, 2010, an increase of $11.1 million or 6%. Gross profit as a percentage of net revenue for the three months ended September 30, 2011 decreased to 58.8% from 61.7% for the three months ended September 30, 2010. The decline in gross margins for the three months ended September 30, 2011 is primarily due to unfavorable movements in foreign currencies, predominantly the appreciation of the Australian dollar against the U.S. dollar as the majority of our manufacturing labor and overhead is denominated in Australian dollars, and declines in our average selling prices. These negative impacts were partially offset by positive impacts associated with a favorable change in product mix, as sales of our higher margin products represented a higher proportion of our sales and cost savings attributable to manufacturing and supply chain improvements.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased for the three months ended September 30, 2011 to $94.2 million from $84.8 million for the three months ended September 30, 2010, an increase of $9.4 million or 11%. Selling, general and administrative expenses, as a percentage of net revenue, were 29.9% for the three months ended September 30, 2011 compared to 30.1% for the three months ended September 30, 2010.

The increase in selling, general and administrative expenses was primarily due to the net appreciation of international currencies against the U.S. dollar, which increased our expenses by approximately $5.4 million for the three months ended September 30, 2011, as reported in U.S. dollars. The increase in selling, general and administrative expenses was also due to an increase in the number of sales and administrative personnel to support our growth and other expenses related to the increase in our sales. As a percentage of net revenue, we expect our future selling, general and administrative expense to be approximately 30%.

Research and Development Expenses

Research and development expenses increased for the three months ended September 30, 2011 to $26.2 million from $19.7 million for the three months ended September 30, 2010, an increase of $6.5 million or 33%. Research and development expenses, as a percentage of net revenue, were 8.3% for the three months ended September 30, 2011, compared to 7.0% for the three months ended September 30, 2010.

The increase in research and development expenses was primarily due to an increase in the number of research and development personnel, consulting and contractor expenses and an increase in materials and tooling costs incurred to facilitate development of new products. The increase in research and development expenses was also due to the net appreciation of the Australian dollar against the U.S. dollar, which increased our expenses by approximately $2.9 million for the three ended September 30, 2011, as reported in U.S. dollars. As a percentage of net revenue, we expect our future research and development expenses to be approximately 8%.

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets for the three months ended September 30, 2011 totaled $3.8 million, as compared to $2.0 million for the three months ended September 30, 2010. The increase in amortization expense is mainly attributable to our recent acquisitions.

Donations to Foundation

For the three months ended September 30, 2011 we donated $Nil to the ResMed Foundation (the “Foundation”), as compared to $1.0 million for the three months ended September 30, 2010. The Foundation was established primarily to promote research into the deleterious medical consequences of untreated sleep-disordered breathing and to increase public and physician awareness of the importance of sleep and respiratory health throughout the world.

Other Income, Net

Other income, net for the three months ended September 30, 2011 was $5.6 million, compared to $10.2 million for the three months ended September 30, 2010. The decrease in other income, net, during the three months ended September 30, 2011, was predominantly due to losses on foreign currency and hedging transactions. This impact was partly offset by an increase in interest income, net, due to additional cash balances and an increase in interest rates on Australian dollar denominated deposits. Other income, net was also favorably impacted by a gain of $2.1 million on re-measurement of a previously held equity interest to its acquisition-date fair value as a result of the acquisition of BiancaMed.

Income Taxes

Our effective income tax rate of approximately 24.0% for the three months ended September 30, 2011 was lower than our effective income tax rate of approximately 25.9% for the three months ended September 30, 2010. The lower effective income tax rate was primarily due to a change in the geographic mix of our taxable income.

We continue to benefit from the lower Australian and Singapore corporate tax rates and certain Australian research and development tax benefits because we generate the majority of our taxable income in Australia.

Net Income

As a result of the factors above, our net income for the three months ended September 30, 2011 was $50.5 million or $0.33 per diluted share compared to net income of $56.7 million or $0.36 per diluted share for the three months ended September 30, 2010, a decrease of 11% and 8%, respectively, over the three months ended September 30, 2010.

Liquidity and Capital Resources

As of September 30, 2011 and June 30, 2011, we had cash and cash equivalents of $610.1 million and $735.3 million, respectively. Working capital was $917.1 million and $1,083.6 million at September 30, 2011 and June 30, 2011, respectively.

Liquidity and Capital Resources, Continued

As of September 30, 2011 and June 30, 2011, our cash and cash equivalent balances held within the United States amounted to $16.8 million and $111.2 million, respectively. Our remaining cash and cash equivalent balances at September 30, 2011 and June 30, 2011, of $593.3 million and $624.1 million, respectively, were held by our non-U.S. subsidiaries, indefinitely invested outside the United States. Our cash and cash equivalent balances are held at highly rated financial institutions. Should we repatriate our cash and cash equivalent balances held outside the U.S., we would have to adjust the income tax provision in the period any such repatriation were to occur.

Inventories at September 30, 2011 were $188.0 million, a decrease of $26.3 million or 12% over the September 30, 2010 balance of $214.2 million. The decrease in inventories mainly reflects a general improvement in inventory management compared to September 30, 2010.

Accounts receivable at September 30, 2011 were $251.1 million, an increase of $25.3 million or 11% over the September 30, 2010 accounts receivable balance of $225.8 million. Accounts receivable days outstanding of 71 days at September 30, 2011 increased by 1 day compared to the 70 days at September 30, 2010. Our allowance for doubtful accounts as a percentage of total accounts receivable at September 30, 2011 and June 30, 2011 was 4.0%. To date we have not experienced any significant decline in the credit quality of our customers and it remains broadly consistent with our past experience.

At September 30, 2011, no capital lease obligations exist. Details of contractual obligations at September 30, 2011 are as follows:
