In the opinion of management, the accompanying balance sheets and related interim statements of income, cash flows, and stockholders’ equity include all adjustments, consisting only of normal recurring items, necessary for their fair presentation in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. Examples include: estimates of loss contingencies, product warranties, product life cycles, product returns, and stock-based compensation forfeiture rates; assumptions such as the elements comprising a software arrangement, including the distinction between upgrades/enhancements and new products; when technological feasibility is achieved for our products; the potential outcome of future tax co nsequences of events that have been recognized in our financial statements or tax returns; estimating the fair value and/or goodwill impairment for our reporting units; and determining when investment impairments are other-than-temporary. Actual results and outcomes may differ from management’s estimates and assumptions. Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with information included in the Microsoft Corporation 2007 Form 10-K. BASIS OF CONSOLIDATION,The financial statements include the accounts of Microsoft Corporation and its subsidiaries. Intercompany transactions and balances have been eliminated. Equity investments in which we exercise significant influence but do not exercise control and are not the primary beneficiary are accounted for using the equity method. Investments in which we are not able to exercise significant influence over the investee and which do not have readily determinable fair values are accounted for under the cost method. RECENT ACCOUNTING PRONOUNCEMENT, On July 1, 2007, we adopted the provisions of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN 48"), Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109, which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under FIN 48, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, c lassification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. Upon adoption, we recognized a $395 million charge to our beginning retained deficit as a cumulative effect of a change in accounting principle. See Note 13 -- Income Taxes. On July 1, 2007, we adopted the Emerging Issues Task Force Issue No. 06-2 ("EITF 06-2"), Accounting for Sabbatical Leave and Other Similar Benefits Pursuant to FASB Statement No. 43. EITF 06-2 requires companies to accrue the costs of compensated absences under a sabbatical or similar benefit arrangement over the requisite service period. Upon adoption, we recognized a $17 million charge to our beginning retained deficit as a cumulative effect of a change in accounting principle. In February 2007, the FASB issued Statement of Financial Accounting Standards ("SFAS") No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. SFAS No. 159 gives us the irrevocable option to carry many financial assets and liabilities at fair values, with changes in fair value recognized in earnings. SFAS No. 159 is effective for us beginning July 1, 2008, although early adoption is permitted. We are currently assessing the potential impact that electing fair value measurement would have on our financial statements. In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. This statement does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. SFAS No. 157 is effective for us beginning July 1, 2008. We are currently assessing the potential impact that adoption of this statement would have on our financial statements. NOTE 2 INVENTORIES 290000000 435000000 252000000 148000000 636000000 544000000 NOTE 3 EARNINGS PER SHARE,Basic earnings per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options, stock awards, and shared performance stock awards. Components of basic and diluted earnings per share were as follows: The following shares attributable to outstanding stock options were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. In addition, the following shared performance stock awards have been excluded from the calculation of diluted earnings per share because the number of shares ultimately issued is contingent on our performance against metrics established for the performance period. 133000000 81000000 137000000 677000000 4000000 9000000 NOTE 4 UNEARNED REVENUE, The components of unearned revenue were as follows: 8489000000 9334000000 1731000000 1839000000 1352000000 1473000000 2673000000 2875000000 3449000000 3652000000 5080000000 5771000000 370000000 348000000 NOTE 5, STOCKHOLDERS' EQUITY, On July 20, 2006, we announced that our Board of Directors authorized two new share repurchase programs: a $20.0 billion tender offer that was completed on August 17, 2006 and authorization for up to an additional $20.0 billion ongoing share repurchase program with an expiration of June 30, 2011. Under the tender offer, we repurchased approximately 155 million shares of common stock, or 1.5% of our common shares outstanding, for approximately $3.8 billion at a price per share of $24.75. On August 18, 2006, we announced that the authorization for the $20.0 billion ongoing share repurchase program had been increased by approximately $16.2 billion. As a result, we are authorized to repurchase additional shares in an amount up to $36.2 billion through June 30, 2011. As of September 30, 2007, approximately $12.8 billion remained of the $36.2 billion approved repurchase amount. All repurchases were made using cash resources. The rep urchase program may be suspended or discontinued at any time without notice. In any period, cash used in financing activities related to common stock repurchased may differ from the comparable change in stockholders’ equity, reflecting timing differences between the recognition of share repurchase transactions and their settlement for cash. We repurchased the following shares of common stock under the above-described repurchase plans: 81000000 285000000 2300000000 7000000000 NOTE 6 INVESTMENT INCOME AND OTHER, The components of investment income and other were as follows: NOTE 7 PRODUCT WARRANTIES, We provide for the estimated costs of hardware and software warranties at the time the related revenue is recognized. For hardware warranty, we estimate the costs based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific hardware warranty terms and conditions vary depending upon the product sold and country in which we do business, but generally include technical support, parts, and labor over a period generally ranging from 90 days to three years. For software warranty, we estimate the costs to provide bug fixes, such as security patches, over the estimated life of the software. The changes in our aggregate product warranty liabilities, which are included in other current liabilities and other long-term liabilities on our balance sheets, were as follows: 850000000 82000000 11000000 -86000000 857000000 NOTE 8 CONTINGENCIES In March 2004, the European Commission issued a decision in its competition law investigation of us. The Commission concluded that we infringed European competition law by refusing to license to our competitors certain protocol technology in the Windows server operating systems and by including streaming media playback features in Windows desktop operating systems. The Commission ordered us to license the protocol technology to our competitors and to develop and make available a version of the Windows desktop operating system that does not include specified media playback software. The Commission also fined us €497 million ($605 million). We appealed the decision to the Court of First Instance. In July 2006, the European Commission determined that we had not complied with the technical documentation requirements of the 2004 Decision, and fined us €281 million ($351 million). We have appe aled this fine to the Court of First Instance. We have expensed and paid both fines, pending resolution of appeals. In March 2007, the European Commission announced a new statement of objections. The new statement of objections claims that the pricing terms we proposed for licensing certain server protocol technology as required by the March 2004 decision are "not reasonable." The statement of objections threatens to impose new fines of up to €500,000 ($706,075) per day from December 2005 to June 2006, up to €2 million ($2.8 million) per day from June to July 2006, and up to €3 million ($4.2 million) per day beginning August 2006. The maximum amount of the potential fine as of October 22, 2007 is $2.1 billion. On September 17, 2007, the Court of First Instance affirmed the European Commission’s 2004 decision in almost all respects. On October 22, 2007, following discussions between the Commission and Microsoft, the Commission announced that steps we had taken brought us into full compliance with the March 2004 Decision. We announced the same day that we would not appeal the decision of the Court of First Instance to the European Court of Justice. On October 24, 2007, we announced that we had discontinued our appeals of two other Commission decisions, including the July 2006 Decision imposing a fine. In December 2005, the Korean Fair Trade Commission ("KFTC") ruled that we abused a market dominant position and engaged in unfair trade practices under the Korean Fair Trade Act. The KFTC stated we violated the Act by building instant messaging and media player features into the Windows PC operating system and streaming media technologies into the Windows server operating system. The KFTC imposed a fine of approximately $34 million which we have expensed and paid. The KFTC’s order issued in February 2006 held that our integration of these media and messaging features into the Windows PC and server operating systems was an abuse of monopoly power and unlawful tying in violation of the Korean Fair Trade Act. The order required us to develop and distribute in Korea versions of Windows XP and its successors that do not include Windows Media Player or Windows Messenger functionality. We also may distribute a second modified version of Windows that contains the media and messenger features, as long as it includes promotional links to certain competing media players and instant messengers. We appealed the KFTC’s decision to the Seoul High Court. In May 2006, the KFTC denied our motion for reconsideration of its ruling, but also dropped the element of its ruling that prohibited us from including media player or instant messaging functionality in any product other than the Windows client operating system for which we have a 50% or greater market share. In October 2007, we submitted a request to the Seoul High Court to withdraw our appeal of the ruling, which was approved by the court and ends the litigation. We are subject to a Consent Decree and Final Judgment that resolved lawsuits brought by the U.S. Department of Justice, 18 states, and the District of Columbia in two separate actions. The Consent Decree imposed various constraints on our Windows operating system businesses. Portions of the Consent Decree are scheduled to expire in November 2007 and we voluntarily agreed to extend expiration of other elements of the Consent Decree to November 2009. On October 16, 2007, some states filed a motion with the U.S. District Court for the District of Columbia seeking to have most of the provisions of the Final Judgment in the action to which they are party extended for five years. This motion is pending. On October 19, 2007, the U.S. Department of Justice and other states advised the Court that they will not seek any extension of the Final Judgments to which they are party. In other ongoing investigations, various foreign governments and several state attorneys general have requested information from us concerning competition, privacy, and security issues. A large number of antitrust and unfair competition class action lawsuits have been filed against us in various state, federal and Canadian courts on behalf of various classes of direct and indirect purchasers of our PC operating system and certain other software products. We obtained dismissals of damages claims of indirect purchasers under federal law and in 15 states. Courts refused to certify classes in two additional states. We have reached agreements to settle all claims that have been made to date in 19 states. Under the settlements, generally class members can obtain vouchers that entitle them to be reimbursed for purchases of a wide variety of platform-neutral computer hardware and software. The total value of vouchers that we may issue varies by state. We will make available to certain schools a percentage of those vouchers that are not issued or claimed (one-half to two-thirds depending on the state). The total value of vouchers we ultimately issue will depend on the number of class members who make claims and are issued vouchers. The maximum value of vouchers to be issued is approximately $2.7 billion. The actual costs of these settlements will be less than that maximum amount, depending on the number of class members and schools that are issued and redeem vouchers. The settlements in all states have received final court approval. Cases in Arizona, Mississippi and Canada have not been settled. We estimate the total cost to resolve all of these cases will range between $1.7 billion and $1.9 billion. The actual cost depends on factors such as the quantity and mix of products for which claims will be made, the number of eligible class members who ultimately use the vouchers, the nature of hardware and software that is acquired using the vouchers, and the cost of administering the claims. At September 30, 2007, we have recorded a liability related to these claims of approximately $1.0 billion, which reflects our estimated exposure of $1.7 billion less payments made to date of approximately $626 million, mostly for administrative expenses and legal fees. In November 2004, Novell, Inc. filed a complaint in U.S. District Court in Utah, now consolidated with other cases in Maryland, asserting antitrust and unfair competition claims against us related to Novell’s ownership of WordPerfect and other productivity applications during the period between June 1994 and March 1996. In June 2005, the trial court granted our motion to dismiss four of six claims of the complaint. Both parties appealed, and in October 2007, the court of appeals affirmed the decision of the trial court, remanding the case to that court for further proceedings. We are vigorously defending more than 45 patent infringement cases. In the case of Eolas Technologies, Inc. and University of California v. Microsoft, filed in U.S. District Court in Illinois in 1999, the plaintiffs alleged infringement by the browser functionality of Windows. In January 2004, the trial court entered final judgment of $565 million, and entered an injunction against distribution of any new infringing products, but stayed execution of the judgment and the injunction pending our appeal. We appealed and in March 2005 the U.S. Court of Appeals for the Federal Circuit reversed the decision and vacated the judgment, based on certain evidentiary rulings of the trial court. The appellate court also reversed the trial court’s decision that the inventors had not engaged in inequitable conduct. The parties have agreed to a settlement pursuant to which Microsoft has taken a license to t he Eolas patents. The settlement did not have a significant financial statement impact. Microsoft and Alcatel-Lucent Matters. Microsoft and Alcatel-Lucent are parties to a number of legal proceedings relating to certain patents of each of the companies. Some of these actions began before the merger of Alcatel and Lucent in 2006. For simplicity, we refer to the post-merger entity of Alcatel-Lucent throughout the following discussion. In 2003, we filed an action in U.S. District Court in California seeking a declaratory judgment that we do not infringe certain Alcatel-Lucent patents. Alcatel-Lucent has asserted claims under these patents against computer manufacturers that sell computers with our operating system and application software pre-installed. In February 2007, the jury returned a verdict in Alcatel-Lucent’s favor in the first of a series of patent trials, and awarded $1.5 billion in damages. In September 2007, on our motions for judgment as a matter of law, the trial court overturned the jury verdict and entered orders dismissing plaintiff’s claims on multiple grounds. Alcatel-Lucent has appealed. The trial court previously dismissed Alcatel-Lucent’s claims with respect to a second group of patents and two patents in a third grouping. Trial on a consolidated group of all remaining patents is scheduled to begin in February 2008. In March 2006, Alcatel-Lucent filed a lawsuit against us in U.S. District Court in California, claiming the Xbox 360 violates one of its patents. In response, we asserted counterclaims that Alcatel-Lucent infringes 10 Microsoft patents by its sales of various products. The case has been set for trial in April 2008. In November 2006, Alcatel-Lucent filed two patent infringement cases against us in U.S. District Court in Texas, asserting Mediaroom and various networking functionalities violate seven of its patents. In April 2007, we asserted infringement counterclaims based on four of our patents relating to functionality similar to that accused by Alcatel-Lucent. The trial on all of the patents is set for January 2009. In February 2007, we filed a complaint against Alcatel-Lucent with the International Trade Commission claiming Alcatel-Lucent is infringing four Microsoft patents related to our unified communications technology and seeking to prevent the import of certain Alcatel-Lucent unified communications products into the U.S. Trial of this matter began in October 2007. In April 2007, the Multimedia Patent Trust filed a complaint against Microsoft, Dell, and Gateway in San Diego, California accusing the parties of infringing three video-related patents that originally belonged to Alcatel-Lucent. Alcatel-Lucent created the Multimedia Patent Trust prior to the companies’ merger and transferred the patents at issue to the trust. The actual costs to resolve these cases will depend upon many factors such as the outcome of post-trial motions, any appeals, and the results of the remaining trials. In Z4 Technologies, Inc. v. Microsoft, filed in U.S. District Court in Texas in September 2004, the plaintiff alleged that Microsoft Windows and Office product activation functionality violates its patent rights. In April 2006, the jury rendered a $115 million verdict against us. In August 2006, the trial court increased damages by $25 million pursuant to the jury’s finding of willful infringement and awarded Z4 $2 million in attorneys’ fees. We have appealed the verdict. In Veritas Operating Corporation v. Microsoft, filed in U.S. District Court in Washington in May 2006, a subsidiary of Symantec filed an action asserting trade secret misappropriation, breach of contract, and patent infringement relating to certain storage technologies. The case is scheduled for trial in May 2008. Adverse outcomes in some or all of the matters described in this section may result in significant monetary damages or injunctive relief against us that would adversely affect distribution of our operating system or application products. We may enter into material settlements because of these risks. We are also subject to a variety of other claims and suits that arise from time to time in the ordinary course of our business. Although management currently believes that resolving claims against us, individually or in aggregate, will not have a material adverse impact on our financial position, our results of operations, or our cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. As of September 30, 2007, we had accrued aggregate liabilities of approximately $700 million in other current liabilities and approximately $650 million in other long-term liabilities for all of the contingent matters described in this note. While we intend to vigorously defend these matters, there exists the possibility of adverse outcomes that we estimate could be up to $4.1 billion in aggregate beyond recorded amounts. Were unfavorable final outcomes to occur, there exists the possibility of a material adverse impact on our financial position and on the results of operations for the period in which the effects become reasonably estimable. NOTE 9 SEGMENT INFORMATION SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, establishes standards for reporting information about operating segments. This standard requires segmentation based on our internal organization and reporting of revenue and operating income based upon internal accounting methods. Our financial reporting systems present various data for management to operate the business, including internal profit and loss statements prepared on a basis not consistent with U.S. GAAP. The segments are designed to allocate resources internally and provide a framework to determine management responsibility. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is o ur Chief Executive Officer. Our five segments are Client; Server and Tools; Online Services Business; Microsoft Business Division; and Entertainment and Devices Division. We have recast certain prior period amounts to conform to the way we internally manage and monitor performance at the segment level in fiscal year 2008. Segment revenue and operating income/(loss) was as follows: Because of our integrated business structure, operating costs included in one segment may benefit other segments, and therefore these segments are not designed to measure operating income or loss directly related to the products included in each segment. Inter-segment cost commissions are estimated by management and used to compensate or charge each segment for such shared costs and to incent shared efforts. Management will continually evaluate the alignment of product development organizations, sales organizations, and inter-segment commissions for segment reporting purposes, which may result in changes to segment allocations in future periods. Reconciling amounts include adjustments to conform with U.S. GAAP and corporate-level activity not specifically attributed to a segment. Significant internal accounting policies that differ from U.S. GAAP relate to revenue recognition, income statement classification, and accelerated amortization for depreciation, stock awards, and performance-based stock awards. In addition, certain revenue and expenses are excluded from segments or included in corporate-level activity, including certain legal settlements and accruals for legal contingencies. Significant reconciling items were as follows: Corporate-level activity excludes stock-based compensation expense and revenue reconciling amounts presented separately in those line items. 4045000000 3315000000 2902000000 2496000000 671000000 536000000 4108000000 3423000000 1928000000 1010000000 108000000 31000000 3244000000 2683000000 886000000 802000000 -262000000 -99000000 2660000000 2229000000 134000000 -145000000 -744000000 -996000000 -1006000000 -940000000 186000000 -58000000 -19000000 4000000 NOTE 10 ACQUISITIONS On August 10, 2007, we acquired all of the outstanding shares of aQuantive, Inc. for $5.9 billion which was paid primarily in cash. Headquartered in Seattle, Washington, aQuantive is a digital marketing company which we expect will play a key role in the future development of our advertising business. We also believe the acquisition will help us build and support next-generation advertiser and publisher solutions in environments such as cross media planning, video-on-demand, and internet protocol television. aQuantive, Inc. was consolidated into our results of operations starting August 10, 2007, the acquisition date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of the acquisition: As a result of this acquisition, we recorded $5.3 billion of goodwill in our Online Services Business operating segment. Of the $938 million of acquired intangible assets, $24 million was assigned to in-process research and development assets and was expensed during the quarter. The remaining acquired intangible assets include $476 million of customer relationships with a weighted average life of six years, $327 million of technology-based intangible assets with a weighted average useful life of four years, and $111 million of other intangible assets with a weighted average life of five years. In addition to aQuantive, we acquired four other entities during the three months ended September 30, 2007 for total consideration of $147 million which was paid primarily in cash. All of the entities were consolidated within Microsoft starting on their respective acquisition dates. Pro forma results of operations have not been presented because the effects of these acquisitions, individually and in aggregate, were not material to our consolidated results of operations. 342000000 273000000 6000000 50000000 938000000 5270000000 109000000 7000000 6995000000 37000000 683000000 338000000 80000000 1138000000 5857000000 NOTE 11 GOODWILL During the three months ended September 30, 2007, we recorded $5.4 billion of goodwill resulting from the five acquisitions described in Note 10 -- Acquisitions. None of the amount recorded as goodwill is expected to be deductible for tax purposes. The purchase price allocation for all of the acquisitions is preliminary and subject to revision as more detailed analyses are completed and additional information about fair value of assets and liabilities become available. Any change in the fair value of the net assets of the acquired company will change the amount of the purchase price allocable to goodwill. 77000000 580000000 552000000 3132000000 419000000 0 70000000 5330000000 0 -9000000 5391000000 77000000 650000000 5882000000 3132000000 410000000 NOTE 12 INTANGIBLE ASSETS The components of finite-lived intangible assets are as follows: Acquired intangibles are generally amortized on a straight-line basis over their weighted average lives. Intangible assets amortization expense was $102 million for the quarter ended September 30, 2007 and $38 million for the quarter ended September 30, 2006. The estimated future amortization expense related to intangible assets as of September 30, 2007 is expected to be $335 million for the remainder of fiscal year 2008, $422 million for fiscal year 2009, $373 million for fiscal year 2010, $296 million for fiscal year 2011, and $292 million for fiscal year 2012 and thereafter. 1003000000 1260000000 601000000 161000000 3025000000 747000000 1307000000 45000000 50000000 465000000 256000000 795000000 551000000 116000000 1718000000 NOTE 13 INCOME TAXES On July 1, 2007, we adopted the provisions of FIN 48, Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109, which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under FIN 48, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. Adopting FIN 48 had the following impact on our financial statements: increased current assets by $228 million, long-term assets by $1.1 billion, long-term liabilities by $2.1 billion, and our retained deficit by $395 million; and decreased our income taxes payable by $394 million. As of July 1, 2007, we had $7.1 billion of unrecognized tax benefits of which $5.3 billion, if recognized, would affect our effective tax rate. Our policy is to include interest and penalties related to unrecognized tax benefits in income tax expense. As of July 1, 2007 we had accrued interest related to uncertain tax positions of $863 million, net of federal income tax benefit, on our balance sheet. We are currently under audit by the IRS for tax years 2000 through 2006. While it is possible that the first audit cycle, 2000 through 2003, may conclude in the next 12 months and that the unrecognized tax benefits we have recorded in relation to this audit may change compared to the liabilities recorded for the period, it is not possible to estimate the effect, if any, of any amount of such change during the next 12 months to previously recorded uncertain tax positions. We are subject to income tax in many jurisdictions outside the United States, none of which are individually material to our financial position, statement of cash flows, or results of operations. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Special Note About Forward-Looking Statements Certain statements in Management’s Discussion and Analysis ("MDandA"), other than purely historical information, including estimates, projections, statements relating to our business plans, objectives and expected operating results, and the assumptions upon which those statements are based, are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements generally are identified by the words "believe," "project," "expect," "anticipate," "estimate," "intend," "strategy," "plan," "may," "should," "will," "would," "will be," "will continue," "will likely result," and similar expressions. Forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties which may cause actual results to differ materially from the forward-looking statements. A detailed discussion of these and oth er risks and uncertainties that could cause actual results and events to differ materially from such forward-looking statements is included in the section entitled "Risk Factors" (refer to Part II, Item 1A). We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events, or otherwise. OVERVIEW The following MDandA is intended to help the reader understand the results of operations and financial condition of Microsoft Corporation. MDandA is provided as a supplement to, and should be read in conjunction with, our financial statements and the accompanying notes to the financial statements ("Notes"). We develop, manufacture, license, and support a wide range of software products for many computing devices. Our software products include operating systems for servers, PCs, and intelligent devices; server applications for distributed computing environments; information worker productivity applications; business solutions applications; and software development tools. We provide consulting and product support services, and we train and certify system integrators and developers. We sell the Xbox video game console and games, the Zune digital music and entertainment device, PC games, and PC peripherals. Online communication and information services are delivered through our MSN portals, channels around the world, and through our search products. Our revenue historically has fluctuated quarterly and has generally been the highest in the second quarter of our fiscal year due to corporate calendar year-end spending trends in our major markets and holiday season spending by consumers. Our Entertainment and Devices Division is particularly seasonal as its products are aimed at the consumer market and are in highest demand during the holiday shopping season. Typically, the Entertainment and Devices Division has generated over 40% of its yearly segment revenues in our second fiscal quarter. In fiscal year 2007, our revenue was highest in the third quarter due to the recognition of $1.7 billion of revenue previously deferred from the Express Upgrade to Windows Vista and Microsoft Office Technology Guarantee programs and pre-shipments of Windows Vista and the 2007 Microsoft Office system. The technology guarantee programs provided customers who purchased current products with free or discounted rights to Windows Vista and the 2007 Microsoft Office system wh en those products became available to consumers. We believe the seasonality of revenue is likely to continue in the future consistent with our experience prior to fiscal year 2007. All growth and percentage comparisons refer to the three months ended September 30, 2007 as compared to the three months ended September 30, 2006 unless otherwise noted. 0.27 0.32 SUMMARY Revenue growth was driven primarily by increased Xbox console and game sales, licensing of Windows Vista and the 2007 Microsoft Office system, and increased revenue associated with Windows Server and SQL Server. Revenue from licensing of Windows Vista and the 2007 Microsoft Office system reflects growth in our OEM channel and growth from Enterprise Agreement licenses. Foreign currency exchange rates accounted for a $205 million or two percentage point increase in revenue during the quarter. Operating income growth was driven primarily by the increased revenue, partially offset by increased Xbox 360 product costs, warranty expenses, and inventory write-downs; data center costs in our Online Services Business; increased Windows Vista product costs; and increased sales and marketing expenses. The increase in sales and marketing expenses was primarily driven by increased headcount-related expenses and marketing costs related to corporate events and our retail channel. Total headcount-related expenses increased 6%, driven by a 12% increase in headcount over the past twelve months and an increase in salaries and benefits for existing headcount, partially offset by decreased stock-based compensation expense. Worldwide macroeconomic factors have a strong correlation to business and consumer demand for our software, services, games, and Internet service offerings. We expect a broad continuation of economic conditions and demand during the remainder of fiscal year 2008. We also expect continued double digit revenue growth. Given our product launches in the second half of fiscal year 2007, we expect revenue growth to be higher in the first half of fiscal year 2008 than in the second half. We estimate worldwide PC shipments will grow between 10% and 12%. We expect a continued favorable impact from changes in year-over-year foreign currency exchange rates in fiscal year 2008. We expect our operating income growth rate to continue to exceed our revenue growth rate. SEGMENT PRODUCT REVENUE/OPERATING INCOME (LOSS) Revenue and operating income/(loss) amounts in this section are presented on a basis consistent with U.S. GAAP and include certain reconciling items attributable to each of the segments. Segment information appearing in Note 9 -- Segment Information is presented on a basis consistent with our current internal management reporting, in accordance with Statement of Financial Accounting Standards ("SFAS") No. 131, Disclosures about Segments of an Enterprise and Related Information. Certain corporate-level activity has been excluded from segment operating results and is analyzed separately. Prior period amounts have been recast to conform to the way we internally manage and monitor performance at the segment level in fiscal year 2008. Client Client offerings consist of premium edition and standard Windows operating systems. Premium offerings are those that include additional functionality and are sold at a price above our standard versions. Premium offerings include Windows XP Professional, XP Media Center Edition, XP Tablet PC Edition, Vista Business, Vista Home Premium, and Vista Ultimate. Standard Windows operating systems include Windows XP Home and Windows Vista Home Basic. Client revenue growth correlates with the growth of purchases of PCs from OEMs that pre-install versions of Windows operating systems because the OEM channel accounts for approximately 80% of total Client revenue. The differences between unit growth rates and revenue growth rates from year to year are affected by changes in the mix of OEM Windows operating systems licensed with premium edition operating systems as a percentage of total OEM Windows operating systems licensed ("OEM premium mix"), changes in the geographical mix, and changes in the channel mix of products sold by large, multi-national OEMs versus those sold by local and regional system builders. Client revenue increased primarily reflecting licensing of Windows Vista. OEM revenue increased $706 million or 25% driven by 20% growth in OEM license units. Revenue from commercial and retail licensing of Windows operating systems increased $116 million or 23% primarily due to strong sales from Enterprise Agreements and legalization efforts in Russia, China, and other emerging markets. The OEM Premium Mix increased 16 percentage points to 75% driven by increased consumer premium mix. Based on our estimates, total worldwide PC shipments from all sources grew 14% to 16% driven by demand in both emerging and mature markets. Client operating income increased reflecting the increased revenue and decreased research and development expenses, partially offset by increased cost of revenue and sales and marketing expenses. Research and development expenses decreased $70 million or 23% primarily reflecting decreased headcount-related expenses. Cost of revenue increased $109 million or 102% driven by Windows Vista product costs while sales and marketing expenses increased $78 million or 36% primarily reflecting increased headcount-related expenses associated with our corporate sales force. Headcount-related expenses decreased 21%, driven by a 7% decrease in headcount over the past twelve months due to the redeployment of resources upon the completion of Windows Vista development and decreased stock-based compensation expense. For the remainder of fiscal year 2008, we expect continued strength in OEM revenue growth, in line with strength in the PC market. We expect PC shipments to grow 10% to 12% for fiscal year 2008. We believe that PC unit growth rates will be higher in the consumer segment than in the business segment and higher in emerging markets than in mature markets. 4138000000 3316000000 0.25 3367000000 2660000000 0.27 Server and Tools Server and Tools offerings consist of server software licenses and client access licenses ("CAL") for Windows Server, Microsoft SQL Server, and other server products. It also includes developer tools, training, certification, Microsoft Press, Premier and Professional product support services, and Microsoft Consulting Services. Server and Tools concentrates on licensing products, applications, tools, content and services that make information technology professionals and developers more productive and efficient. We use multiple channels for licensing including pre-installed OEM versions, licenses through partners, and licenses directly to end customers. We sell licenses both as one-time licenses and as multi-year volume licenses. Server and Tools revenue increased reflecting growth in both product and services revenue. Server and server application revenue (including CAL revenue) and developer tools, training, and certificate revenue increased $262 million or 13% primarily driven by growth in new and recurring volume licensing of Windows Server and SQL Server products and reflects broad adoption of the Windows Platform and applications. Consulting, Premier and Professional product support services revenue increased $142 million or 32% primarily due to higher demand for consulting and support services in corporate enterprises. Foreign currency exchange rates accounted for a $65 million or two percentage point increase in revenue. Server and Tools operating income increased primarily reflecting the increased revenue, partially offset by increased sales and marketing expenses and cost of revenue for services. Sales and marketing expenses increased $133 million or 18% primarily reflecting increased headcount-related expenses associated with our corporate sales force. Cost of revenue increased $76 million or 15% reflecting the growth in services provided. Headcount-related expenses increased 4%, driven by a 15% increase in headcount over the past twelve months and an increase in salaries and benefits for existing headcount, partially offset by decreased stock-based compensation expense. We expect continued revenue growth in both product and services offerings related to the release of new versions of Visual Studio, Windows Server, and SQL Server products. 2900000000 2496000000 0.16 962000000 771000000 0.25 Online Services Business The Online Services Business ("OSB") provides personal communications services, such as e-mail and instant messaging, online information offerings, such as Live Search, and the MSN portals and channels around the world. OSB also provides a variety of online services such as MSN Internet Access and MSN Premium Web Services. We earn revenue primarily from online advertising, from consumers and partners through subscriptions and transactions generated from online paid services, and from MSN narrowband Internet access subscribers. We continue to launch new online initiatives and expect to do so in the future. In the first quarter of fiscal year 2008, we launched a new release of Windows Live Search and a beta version of Windows Live Suite and updated the MSN Video Services. During the quarter ended September 30, 2007, we completed our acquisition of aQuantive, Inc. for consideration of $5.9 billion. We expect aQuantive, Inc., a digital marketing company, to play a key role in the future development of our advertising business. We believe the acquisition will help us build and support next-generation advertiser and publisher solutions in environments such as cross media planning, video-on-demand, and internet protocol television. aQuantive, Inc. was consolidated into our results of operations starting August 10, 2007, the acquisition date. OSB revenue increased driven primarily by online advertising revenue which grew $120 million or 33% to $487 million. This increase reflects growth in our existing online advertising business for search, home page, email, and messaging services and includes $29 million of aQuantive online advertising revenue. During the quarter, we also recognized $51 million of aQuantive advertising agency revenue. The increase in revenue was partially offset by a $33 million or 32% decrease in access revenue. As of September 30, 2007 and 2006, we had approximately 405 million and 340 million Windows Live IDs, respectively. OSB operating loss increased driven primarily by increased cost of revenue, increased sales and marketing expenses, and increased research and development expenses, partially offset by the increased revenue. OSB operating loss includes a $58 million loss from aQuantive, including a $24 million in-process research and development write-off and $30 million of amortization of intangible assets. The $151 million or 63% increase in cost of revenue was primarily driven by increased data center costs, online content expenses, and aQuantive-related expenses. Sales and marketing expenses increased $69 million or 42% primarily due to increased marketing costs and amortization of customer-related intangible assets, while research and development expenses increased $60 million or 28% primarily as a result of increased headcount-related expenses and product development costs. Headcount-related expenses increased 10%, driven by a 20% increase in headcount over the past twelve months and an increase in salaries and benefits for existing headcount, partially offset by decreased stock-based compensation expense. For the remainder of fiscal year 2008, we expect continued growth in online advertising revenue as the portals, channels, and communications services continue to expand globally and the overall Internet advertising market continues to expand. Online advertising revenue is expected to benefit from our acquisition of aQuantive while revenue from narrowband Internet Access is expected to continue to decline. 671000000 536000000 0.25 -264000000 -102000000 Microsoft Business Division Microsoft Business Division ("MBD") offerings consist of the Microsoft Office system and Microsoft Dynamics business solutions. Microsoft Office system products are designed to increase personal, team, and organization productivity through a range of programs, services, and software solutions. Growth of revenue from the Microsoft Office system offerings, which generate over 90% of MBD revenue, depends on our ability to add value to the core Office product set and to continue to expand our product offerings in other information worker areas such as enterprise content management, collaboration, unified communications, and business intelligence. Microsoft Dynamics products provide business solutions for financial management, customer relationship management, supply chain management, and analytics applications for small and mid-size businesses, large organizations, and divisions of global enterprises. We evaluate our results based upon the nature of the end user in two primary parts: business revenue which inclu des Microsoft Office system revenue generated through volume licensing agreements and Microsoft Dynamics revenue, and consumer revenue which includes revenue from retail packaged product sales and OEM revenue. MBD revenue increased primarily reflecting licensing of the 2007 Microsoft Office system. Business revenue increased $663 million or 25% primarily as a result of growth in volume licensing agreement revenue and strong transactional license sales to businesses. The increase in business revenue also included an 18% increase in Microsoft Dynamics customer billings. Consumer revenue increased $29 million or 4% as a result of strong retail packaged product sales partially offset by a reduction of licenses sold through OEMs. Foreign currency exchange rates accounted for a $93 million or two percentage point increase in revenue. MBD operating income increased reflecting the increased revenue, partially offset by increased sales and marketing expenses of $152 million or 22% and increased cost of revenue of $49 million or 29%. The increase in sales and marketing expenses primarily reflects increased headcount-related expenses associated with our corporate sales force. The increase in cost of revenue primarily reflects an increase in online costs related to the recent acquisition of Tellme Networks. Headcount-related expenses decreased 2%, driven by a decrease in stock-based compensation expense, partially offset by a 4% increase in headcount over the past twelve months and an increase in salaries and benefits for existing headcount. For the remainder of fiscal year 2008, we expect revenue to continue to increase over the prior year due to the strong performance of 2007 Microsoft Office system. We continue to develop plans to grow revenue in new areas such as unified communications and through our existing portfolio of Microsoft Dynamics products. 4111000000 3419000000 0.20 2694000000 2227000000 0.21 Entertainment and Devices Division The The Entertainment and Devices Division ("EDD") products include the Microsoft Xbox video game console system, PC games, consumer software and hardware products, the Zune digital music and entertainment device, Mediaroom (our internet protocol television software), the Windows Mobile software platform, the Windows Embedded device operating system, and Windows Automotive. The success of video game consoles is determined by console innovation and quality, the portfolio of video game content for the console, online offerings, and the market share of the console. We believe that the functionality of the Xbox 360 console, games portfolio, and online offerings are well positioned relative to competitive consoles. EDD revenue increased primarily due to increased Xbox 360 console and game sales. Xbox and PC game revenue increased $895 million or 148% as a result of increased Xbox 360 console sales, video game sales led by Halo 3, and Xbox 360 accessory sales. We shipped 1.8 million Xbox 360 consoles in the current quarter as compared to 0.9 million consoles in the first quarter of fiscal year 2007. Halo 3 was launched in September 2007 and generated approximately $330 million of revenue during the quarter. Increased revenue from sales of consumer hardware products, the Windows Mobile software platform, and Zune was offset by decreased revenue from Mediaroom. EDD operating income increased primarily due to the increased revenue, partially offset by increased cost of revenue and increased sales and marketing expenses. Cost of revenue increased $584 million or 99% primarily driven by the increase in consoles sold and increased Xbox 360 console warranty expenses and inventory write-downs. Sales and marketing expenses increased $49 million or 23% primarily related to Xbox 360, including Halo 3, and Zune. Headcount-related expenses increased 6%, reflecting a 7% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by decreased stock-based compensation expense. For the remainder of fiscal year 2008, we expect revenue to increase due to the increased sales of Xbox 360 consoles and related games, accessories, and services, and sales of Zune products. Revenue from existing mobility and embedded devices is expected to increase due to unit volume increases of Windows Mobile software driven by increased market demand for phone-enabled devices and Windows Embedded operating systems. 19290000000 1011000000 0.91 165000000 -142000000 Corporate-Level Activity Certain corporate-level results are not allocated to our segments. Those results include expenses related to corporate operations related to broad-based sales and marketing, product support services, human resources, legal, finance, information technology, corporate development and procurement activities, research and development and other costs, and legal settlements and contingencies. Corporate-level expenses increased primarily reflecting increased headcount-related expenses, partially offset by decreased costs for legal settlements and legal contingencies. Headcount-related expenses increased 15%, driven by an 8% increase in headcount and an increase in salaries and benefits for existing headcount. We incurred $40 million in legal charges during the three months ended September 30, 2007, compared with $87 million in legal charges during the three months ended September 30, 2006. -1006000000 -940000000 0.07 Cost of Revenue Cost of revenue includes manufacturing and distribution costs for products sold and programs licensed, operating costs related to product support service centers and product distribution centers, costs incurred to support and maintain Internet-based products and services, warranty costs, inventory write-downs, and costs associated with the delivery of consulting services. Cost of revenue increased primarily driven by an increase in Xbox-related costs (increased product costs, warranty costs, and inventory write-downs), increased OSB data center costs, increased Windows Vista product costs, and costs associated with the growth in consulting services. 0.58 0.19 0.16 0.03 Research and Development Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related expenses associated with product development. Research and development expenses also include third-party development and programming costs, localization costs incurred to translate software for international markets, and the amortization of purchased software code and services content. The increase in research and development expenses was primarily driven by increased headcount-related expenses of 1%, which reflects a 7% increase in headcount and an increase in salaries and benefits for existing headcount, offset by a decrease in stock-based compensation expense. 0.03 0.13 0.17 -0.04 Sales and Marketing Sales and marketing expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related expenses associated with sales and marketing personnel and advertising, promotions, trade shows, seminars, and other programs. Sales and marketing expenses increased primarily as a result of increased headcount-related expenses and marketing costs related to corporate events and our retail channel. Headcount-related expenses increased 12%, reflecting both an 8% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. 0.19 0.19 0.20 -0.01 General and Administrative General and administrative costs include payroll, employee benefits, stock-based compensation expense and other headcount-related expenses associated with finance, legal, facilities, certain human resources, other administrative headcount, and legal and other administrative fees. General and administrative costs increased primarily reflecting increased consulting and professional fees, partially offset by decreased legal settlements expense. We incurred $40 million in legal charges during the three months ended September 30, 2007, compared with $87 million in legal charges during the three months ended September 30, 2006. Headcount-related expenses increased 4%, reflecting both a 14% increase in headcount and an increase in salaries and benefits for existing headcount. 0.08 0.05 0.06 -0.01 Investment Income, Income Taxes, and Other Investment Income and Other The components of investment income and other were as follows: Dividends and interest income declined, reflecting a decline in the average balance of dividend and interest-bearing investments coupled with lower interest rates received on our fixed-income investments. Net recognized gains decreased primarily due to fewer gains on the sale of equity investments and losses on sales of fixed-income investments in the current period as compared to gains in the prior period. Other-than-temporary impairments were not material in both the three months ended September 30, 2007 and in the prior period. Other of $128 million includes the correction of several immaterial items from prior periods. We experienced net gains on equity derivatives, interest rate derivatives, and commodity derivatives in the current period as compared to net losses in the prior period. Additionally, net losses on foreign exchange contracts were similar in both the current and prior periods. We use derivative instruments to manage exposures and to facilitate portfolio diversification related to interest rates, equity and commodity prices, and foreign currency markets. Gains and losses arising from derivatives not designated as accounting hedges are in large part economically offset by unrealized losses and gains, respectively, in the underlying securities which are recorded as a component of other comprehensive income. Net losses related to foreign currency contracts include changes in time value of options used to hedge anticipated foreign currency revenues. We lend certain fixed-income and equity securities to increase investment returns. The loaned securities continue to be carried as investments on our balance sheet. Collateral and/or security interest is determined based upon the underlying security and the creditworthiness of the borrower. Cash collateral is recorded as an asset with a corresponding liability. We anticipate that the magnitude of securities loaned under this program will remain relatively consistent during the fiscal year. 239000000 369000000 151000000 363000000 36000000 -156000000 -128000000 -9000000 Income Taxes Our effective tax rate was 31% for the three months ended September 30, 2007 and 2006. On July 1, 2007, we adopted the provisions of FIN 48, Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109, which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under FIN 48, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. Adopting FIN 48 had the following impact on our financial statements: increased current assets by $228 million, long-term assets by $1.1 billion, long-term liabilities by $2.1 billion, and our retained deficit by $395 million; and decreased our income taxes payable by $394 million. As of July 1, 2007, we had $7.1 billion of unrecognized tax benefits of which $5.3 billion, if recognized, would affect our effective tax rate. Our policy is to include interest and penalties related to unrecognized tax benefits in income tax expense. As of July 1, 2007, we had accrued interest related to uncertain tax positions of $863 million, net of federal income tax benefit, on our balance sheet. Financial Condition Cash and equivalents and short-term investments totaled $21.6 billion as of September 30, 2007, compared with $23.4 billion as of June 30, 2007. Equity and other investments were $9.7 billion as of September 30, 2007, compared with $10.1 billion as of June 30, 2007. Our investments consist primarily of fixed-income securities, diversified among industries and individual issuers. Our investments are generally liquid and investment grade. The portfolio is invested predominantly in U.S.-dollar-denominated securities, but also includes foreign-denominated securities in order to diversify financial risk. The portfolio is primarily invested in short-term securities to facilitate rapid deployment for immediate cash needs. As a result of the special dividend paid in the second quarter of fiscal year 2005 and shares repurchased, our retained deficit, including accumulated other comprehensive income, was $28.6 billion at September 30, 2007. Our retained deficit is not expected to impact our future ability to operate or pay dividends given our continuing profitability and strong cash and financial position. Unearned Revenue Unearned revenue from volume licensing programs represents customer billings, paid either upfront or annually at the beginning of each billing coverage period, that are accounted for as subscriptions with revenue recognized ratably over the billing coverage period. For certain other licensing arrangements, revenue attributable to undelivered elements, including free post-delivery telephone support and the right to receive unspecified upgrades/enhancements of Microsoft Internet Explorer on a when-and-if-available basis for Windows XP, is based on the sales price of those elements when sold separately and is recognized ratably on a straight-line basis over the life cycle of the related product. Other unearned revenue includes services, Microsoft Dynamics business solution products, Xbox Live subscriptions, advertising, and TV platform for which we have been paid upfront and earn the revenue when we provide the service or software, or otherwise meet the revenue recognition criteria. Unearned revenue as of September 30, 2007 decreased $1.1 billion from June 30, 2007, reflecting recognition of unearned revenue from multi-year licensing that outpaced multi-year licensing deferrals by $845 million, a $108 million decrease in revenue deferred for undelivered elements, and a $121 million decrease primarily in unearned revenue for services and subscription services. The following table outlines the expected recognition of unearned revenue as of September 30, 2007: See Note 4 -- Unearned Revenue (Part I, Item 1). 4052000000 2992000000 1952000000 791000000 1785000000 Cash Flows Cash flow from operations for the three months ended September 30, 2007, increased $1.8 billion from the first quarter of fiscal year 2007 to $5.9 billion, due to increased cash collections from customers reflecting our continued revenue growth and $2.8 billion from conversion of accounts receivable to cash. The increase also includes an $845 million reduction in cash used for other current assets reflecting the inventory and product costs cash outflow in the first quarter of fiscal year 2007 related to Xbox 360 consoles. Cash used for financing was $3.2 billion in the first quarter of fiscal year 2008, a decrease of $5.0 billion from the corresponding period in fiscal year 2007. The decrease reflects $2.9 billion of common stock repurchases in the three months ended September 30, 2007, compared with $7.7 billion in the prior year that included the impact of our tender offer completed on August 17, 2006. Cash used for investing was $2.3 billion in the first quarter of fiscal year 2008, as compared with cash provided by investing of $6.5 billion in the first quarter of fiscal year 2007. This $8.7 billion decrease in cash from investing activities includes a $5.1 billion increase in cash paid for acquisition of companies, reflecting the purchase of aQuantive in the first quarter of fiscal year 2008, and a $3.2 billion decrease in cash from combined investment purchases, sales, and maturities. We have no material long-term debt. Stockholders’ equity at September 30, 2007, was $32.1 billion. We will continue to invest in sales, marketing, product support infrastructure, and existing and advanced areas of technology. Additions to property and equipment will continue, including new facilities, data centers, and computer systems for research and development, sales and marketing, support, and administrative staff. We have operating leases for most U.S. and international sales and support offices and certain equipment. We have not engaged in any related party transactions or arrangements with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity or the availability of requirements for capital resources. On July 20, 2006, we announced that our Board of Directors authorized two new share repurchase programs: a $20.0 billion tender offer that was completed on August 17, 2006 and authorization for up to an additional $20.0 billion ongoing share repurchase program with an expiration of June 30, 2011. Under the tender offer, we repurchased approximately 155 million shares of common stock, or 1.5% of our common shares outstanding, for approximately $3.8 billion at a price per share of $24.75. On August 18, 2006, we announced that the authorization for the $20.0 billion ongoing share repurchase program had been increased by approximately $16.2 billion. As a result, we are authorized to repurchase additional shares in an amount up to $36.2 billion through June 30, 2011. As of September 30, 2007, approximately $12.8 billion remained of the $36.2 billion approved repurchase amount. Our Board of Directors declared the following dividends: (1) This dividend was included in other current liabilities on our balance sheet as of September 30, 2007. We believe existing cash and equivalents and short-term investments, together with funds generated from operations, should be sufficient to meet operating requirements, regular quarterly dividends, and planned share repurchases. Our philosophy regarding the maintenance of a balance sheet with a large component of cash and short-term investments, as well as equity and other investments, reflects our views on potential future capital requirements relating to research and development, creation and expansion of sales distribution channels, investments and acquisitions, share dilution management, legal risks, and challenges to our business model. We regularly assess our investment management approach in view of our current and potential future needs. 2007-09-12 0.11 2007-11-15 1029000000 2007-12-13 2006-09-13 0.10 2007-11-16 980000000 2006-12-14 Off-Balance Sheet Arrangements We provide indemnifications of varying scope and amount to certain customers against claims of intellectual property infringement made by third parties arising from the use of our products. We evaluate estimated losses for such indemnifications under SFAS No. 5, Accounting for Contingencies, as interpreted by FASB Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. We consider factors such as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. To date, we have not encountered material costs as a result of such obligations and have not accrued any material liabilities related to such indemnifications in our financial statements. RECENT ACCOUNTING PRONOUNCEMENTS On July 1, 2007, we adopted the provisions of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN 48"), Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109, which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under FIN 48, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. Upon adoption, we recognized a $395 million charge to our begi nning retained deficit as a cumulative effect of a change in accounting principle. See Note 13 -- Income Taxes (Part I, Item 1). On July 1, 2007, we adopted the Emerging Issues Task Force Issue No. 06-2 ("EITF 06-2"), Accounting for Sabbatical Leave and Other Similar Benefits Pursuant to FASB Statement No. 43. EITF 06-2 requires companies to accrue the costs of compensated absences under a sabbatical or similar benefit arrangement over the requisite service period. Upon adoption, we recognized a $17 million charge to our beginning retained deficit as a cumulative effect of a change in accounting principle. In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. SFAS No. 159 gives us the irrevocable option to carry many financial assets and liabilities at fair values, with changes in fair value recognized in earnings. SFAS No. 159 is effective for us beginning July 1, 2008, although early adoption is permitted. We are currently assessing the potential impact that electing fair value measurement would have on our financial statements. In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. This statement is effective for us beginning July 1, 2008. We currently are assessing the potential impact that adoption of SFAS No. 157 would have on our financial statements. APPLICATION OF CRITICAL ACCOUNTING POLICIES Our financial statements and accompanying notes are prepared in accordance with U.S. GAAP. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. These estimates and assumptions are affected by management’s application of accounting policies. Critical accounting policies for us include revenue recognition, impairment of investment securities, impairment of goodwill, accounting for research and development costs, accounting for contingencies, accounting for income taxes, and accounting for stock-based compensation. We account for the licensing of software in accordance with American Institute of Certified Public Accountants Statement of Position ("SOP") 97-2, Software Revenue Recognition. The application of SOP 97-2 requires judgment, including whether a software arrangement includes multiple elements, and if so, whether vendor-specific objective evidence ("VSOE") of fair value exists for those elements. For some of our products, customers receive certain elements of our products over a period of time. These elements include free post-delivery telephone support and the right to receive unspecified upgrades/enhancements of Microsoft Internet Explorer on a when-and-if-available basis. The fair value of these elements is recognized over the estimated life cycle for the Windows XP and previous PC operating systems. For Windows Vista, there are no significant undelivered elements and accordingly, no license revenue is deferred for Windows Vista sales. Changes to the elements in a software arrangement, the ability to identif y VSOE for those elements, the fair value of the respective elements, and changes to a product’s estimated life cycle could materially impact the amount of earned and unearned revenue. Judgment also is required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products. SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, and SAB Topic 5M, Accounting for Noncurrent Marketable Equity Securities, provide guidance on determining when an investment is other-than-temporarily impaired. Investments are reviewed quarterly for indicators of other-than-temporary impairment. This determination requires significant judgment. In making this judgment, we employ a systematic methodology quarterly that considers available quantitative and qualitative evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, we evaluate, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and our intent and ability to hold the investment. We also consider specific adverse conditions related to the financial health of and business outlook for the investee, including industry and sector performance, changes in technology, operational and financing cash flow facto rs, and rating agency actions. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis in the investment is established. If market, industry, and/or investee conditions deteriorate, we may incur future impairments. SFAS No. 142, Goodwill and Other Intangible Assets, requires that goodwill be tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (July 1 for us) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition or sale or disposition of a significant portion of a reporting unit. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. The fair value of each reporting unit is estimated using a discounted cash flow methodology. This requires significant judgments including e stimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, the useful life over which cash flows will occur, and determination of our weighted average cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit. We allocate goodwill to reporting units based on the reporting unit expected to benefit from the combination. We evaluate our reporting units on an annual basis and, if necessary, reassign goodwill using a relative fair value allocation approach. We account for research and development costs in accordance with applicable accounting pronouncements, including SFAS No. 2, Accounting for Research and Development Costs, and SFAS No. 86, Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed. SFAS No. 86 specifies that costs incurred internally in researching and developing a computer software product should be charged to expense until technological feasibility has been established for the product. Once technological feasibility is established, all software costs should be capitalized until the product is available for general release to customers. Judgment is required in determining when technological feasibility of a product is established. We have determined that technological feasibility for our software products is reached after all high-risk development issues have been resolved through coding and testing. This is generally shortly before the products are released to manufacturing. We determined that technological fea sibility was reached with Windows Vista and the 2007 Microsoft Office system during the second quarter of fiscal year 2007 and accordingly, we capitalized approximately $120 million of software development costs. The amortization of these costs will be included in cost of revenue over the estimated life of the products. Previously, costs incurred prior to technological feasibility were not material and were expensed as incurred. The outcomes of legal proceedings and claims brought against us are subject to significant uncertainty. SFAS No. 5, Accounting for Contingencies, requires that an estimated loss from a loss contingency such as a legal proceeding or claim should be accrued by a charge to income if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. Disclosure of a contingency is required if there is at least a reasonable possibility that a loss has been incurred. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Changes in these factors could materially impact our results of operations, financial position, or our cash flows. SFAS No. 109, Accounting for Income Taxes, establishes financial accounting and reporting standards for the effect of income taxes. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position, results of operations, or cash flows. Accruals for uncertain tax positions are provided for in accordance with the requirements of FIN 48. We account for stock-based compensation in accordance with SFAS No. 123(R), Share-Based Payment. Under the fair value recognition provisions of this statement, share-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period. Determining the fair value of share-based awards at the grant date requires judgment, including estimating expected dividends. In addition, judgment is also required in estimating the amount of share-based awards that are expected to be forfeited. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted. We account for product warranties in accordance with SFAS No. 5, Accounting for Contingencies. We provide for the estimated costs of hardware and software warranties at the time the related revenue is recognized. For hardware warranty, we estimate the costs based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific hardware warranty terms and conditions vary depending upon the product sold and country in which we do business, but generally include technical support, parts, and labor over a period generally ranging from 90 days to three years. For software warranty, we estimate the costs to provide bug fixes, such as security patches, over the estimated life of the software. We reevaluate our estimates at least quarterly to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to foreign currency, interest rate, fixed-income, equity, and commodity price risks. A portion of these risks is hedged, but fluctuations could impact our results of operations, financial position, and cash flows. We hedge a portion of anticipated revenue and accounts receivable exposure to foreign currency fluctuations, primarily with option contracts. We monitor our foreign currency exposures daily to maximize the overall effectiveness of our foreign currency hedge positions. Principal currencies hedged include the euro, Japanese yen, British pound, and Canadian dollar. Fixed-income securities and interest rate derivatives are subject primarily to interest rate risk. The portfolio is diversified and structured to minimize credit risk. Securities held in our equity and other investments portfolio and equity derivatives are subject to price risk, and are generally not hedged. However, we use put-call collars to hedge our price risk on certain equity securities that are held primarily for strat egic purposes. Commodity derivatives held for the purpose of portfolio diversification are subject to commodity price risk. We use a value-at-risk ("VaR") model to estimate and quantify our market risks. VaR is the expected loss, for a given confidence level, in fair value of our portfolio due to adverse market movements over a defined time horizon. The VaR model is not intended to represent actual losses in fair value, but is used as a risk estimation and management tool. The model used for currencies, equities, and commodities is geometric Brownian motion, which allows incorporation of optionality with regard to these risk exposures. For interest rate risk, exposures such as key rate durations and spread durations are used in calculations that reflect the principle that fixed-income security prices revert to maturity value over time. VaR is calculated by computing the exposures of each holding’s market value to a range of over 1,000 equity, fixed-income, foreign exchange, and commodity risk factors. The exposures are then used to compute the parameters of a distribution of potential changes in the total market value of all holdings, taking into account the weighted historical volatilities of the different rates and prices and the weighted historical correlations among the different rates and prices. The VaR is then calculated as the total loss that will not be exceeded at the 97.5 percentile confidence level or, alternatively stated, the losses could exceed the VaR in 25 out of 1,000 cases. Several risk factors are not captured in the model, including liquidity risk, operational risk, credit risk, and legal risk. Certain securities in our equity portfolio are held for strategic purposes. We hedge the value of a portion of these securities through the use of derivative contracts such as put-call collars. In these arrangements, we hedge a security’s equity price risk below the purchased put strike and forgo most or all of the benefits of the security’s appreciation above the sold call strike. We also hold equity securities for general investment return purposes. We have incurred material impairment charges related to these securities in previous periods. The VaR amounts disclosed below are used as a risk management tool and reflect an estimate of potential reductions in fair value of our portfolio. Losses in fair value over the specified holding period can exceed the reported VaR by significant amounts and can also accumulate over a longer time horizon than the specified holding period used in the VaR analysis. VaR amounts are not necessarily reflective of potential accounting losses, including determinations of other-than-temporary losses in fair value in accordance with U.S. GAAP. VaR numbers are shown separately for interest rate, currency rate, equity price, and commodity price risks. These VaR numbers include the underlying portfolio positions and related hedges. We use historical data to estimate VaR. Given the reliance on historical data, VaR is most effective in estimating risk exposures in markets in which there are no fundamental changes or shifts in market conditions. An inherent limitation in VaR is that the distribution of past changes in market risk factors may not produce accurate predictions of future market risk. The following table sets forth the one-day VaR for substantially all of our positions as of and for the three months ended September 30, 2007, and as of June 30, 2007: Total one-day VaR for the combined risk categories was $126 million at September 30, 2007 and $95 million at June 30, 2007. The total VaR is 34% less at September 30, 2007, and 39% less at June 30, 2007, than the sum of the separate risk categories in the above table due to the diversification benefit of the overall portfolio. 36000000 91000000 58000000 7000000 34000000 77000000 56000000 6000000 37000000 98000000 60000000 7000000 31000000 60000000 52000000 5000000 34000000 55000000 60000000 7000000 ITEM 4. CONTROLS AND PROCEDURES Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures as required by Exchange Act Rule 13a-15(b) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these disclosure controls and procedures are effective. There were no changes in our internal control over financial reporting during the quarter ended September 30, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 1. LEGAL PROCEEDINGS On September 17, 2007, the European Union Court of First instance affirmed in almost all respects the 2004 decision of the European Commission against Microsoft under European competition law, leaving in place a previously-levied fine of €497 million ($605 million). The primary issues on appeal were integration of media player functionality into the Windows operating system and the requirement to license Windows communication protocols to competing server operating system vendors. On October 22, 2007, following discussions between the Commission and Microsoft, the Commission announced that steps we had taken brought us into full compliance with the March 2004 Decision. We announced the same day that we would not appeal the decision of the Court of First Instance to the European Court of Justice. On October 24, 2007, we announced that we had discontinued our appeals of two other Commission decisions, including the July 2006 Decision imposing a fine. In September 2007, in the patent infringement lawsuit brought by Alcatel-Lucent, the U.S. District Court in San Diego, California overturned a $1.5 billion jury verdict against us and entered orders dismissing plaintiff’s claims on multiple grounds. Alcatel-Lucent has appealed. See Note 8 -- Contingencies (Part I, Item 1) for more information about these and other legal proceedings in which we are involved. ITEM 1A. RISK FACTORS Our operations and financial results are subject to various risks and uncertainties, including those described below, that could adversely affect our business, financial condition, results of operations, cash flows, and trading price of our common stock. Challenges to our business model may reduce our revenues and operating margins. Our business model has been based upon customers paying a fee to license software that we developed and distributed. Under this license-based software model, software developers bear the costs of converting original ideas into software products through investments in research and development, offsetting these costs with the revenue received from the distribution of their products. In recent years, certain "open source" software business models have evolved into a growing challenge to our license-based software model. Open source commonly refers to software whose source code is subject to a license allowing it to be modified, combined with other software and redistributed, subject to restrictions set forth in the license. A number of commercial firms compete with us using an open source business model by modifying and then distributing open source software to end users at nominal cost and earning revenue on complementary services and products. These firms do not have to bear the full costs of research and dev elopment for the software. A prominent example of open source software is the Linux operating system. Although we believe our products provide customers with significant advantages in security, productivity, and total cost of ownership, the popularization of the open source software model continues to pose a significant challenge to our business model, including continuing efforts by proponents of open source software to convince governments worldwide to mandate the use of open source software in their purchase and deployment of software products. To the extent open source software gains increasing market acceptance, sales of our products may decline, we may have to reduce the prices we charge for our products, and revenue and operating margins may consequently decline. Another development is the software-as-a-service business model, by which companies provide applications, data, and related services over the Internet. Providers use primarily advertising or subscription-based revenue models. Recent advances in computing and communications technologies have made this model viable and enabled the rapid growth of some of our competitors. We are devoting significant resources toward developing our own competing software plus services strategies. It is uncertain whether these strategies will prove successful. We face intense competition. We continue to experience intense competition across all markets for our products and services. Our competitors range in size from Fortune 100 companies to small, specialized single-product businesses and open source community-based projects. Although we believe the breadth of our businesses and product portfolio are a competitive advantage, our competitors that are focused on narrower product lines may be more effective in devoting technical, marketing, and financial resources to compete with us. In addition, barriers to entry in our businesses generally are low and products, once developed, can be distributed broadly and quickly at relatively low cost. Open source software vendors are devoting considerable efforts to developing software that mimics the features and functionality of our products. In response to competition, we are developing versions of our products with basic functionality that are sold at lower prices than the standard versions. These competitive pressures may result in decreased sales volumes, price reductions, and/or increased operating costs, such as for marketing and sales incentives, resulting in lower revenue, gross margins and operating income. We may not be able to adequately protect our intellectual property rights. Protecting our global intellectual property rights and combating unlicensed copying and use of software and other intellectual property is difficult. While piracy adversely affects U.S. revenue, the impact on revenue from outside the U.S. is more significant, particularly in countries where laws are less protective of intellectual property rights. Similarly, the absence of harmonized patent laws makes it more difficult to ensure consistent respect for patent rights. Throughout the world, we actively educate consumers about the benefits of licensing genuine products and obtaining indemnification benefits for intellectual property risks, and we educate lawmakers about the advantages of a business climate where intellectual property rights are protected. However, continued educational and enforcement efforts may fail to enhance revenue. Reductions in the legal protection for software intellectual property rights or additional compliance burdens could both adversely affect revenue. Third parties may claim we infringe their intellectual property rights. From time to time we receive notices from others claiming we infringe their intellectual property rights. The number of these claims may grow. To resolve these claims we may enter into royalty and licensing agreements on less favorable terms, stop selling or redesign affected products, or pay damages to satisfy indemnification commitments with our customers. Such agreements may cause operating margins to decline. We have made and expect to continue making significant expenditures to settle claims related to the use of technology and intellectual property rights as part of our strategy to manage this risk. We may not be able to protect our source code from copying if there is an unauthorized disclosure of source code. Source code, the detailed program commands for our operating systems and other software programs, is critical to our business. Although we license portions of our application and operating system source code to a number of licensees, we take significant measures to protect the secrecy of large portions of our source code. If an unauthorized disclosure of a significant portion of our source code occurs, we could potentially lose future trade secret protection for that source code. This could make it easier for third parties to compete with our products by copying functionality, which could adversely affect our revenue and operating margins. Unauthorized disclosure of source code could also increase the security risks described in the next paragraph. Security vulnerabilities in our products could lead to reduced revenues or to liability claims. Maintaining the security of computers and computer networks is a critical issue for us and our customers. Hackers develop and deploy viruses, worms, and other malicious software programs that attack our products. Although this is an industry-wide problem that affects computers across all platforms, it affects our products in particular because hackers tend to focus their efforts on the most popular operating systems and programs and we expect them to continue to do so. We devote significant resources to address security vulnerabilities through: * engineering more secure products; * enhancing security and reliability features in our products; * helping our customers make the best use of our products and services to protect against computer viruses and other attacks; * improving the deployment of software updates to address security vulnerabilities; * investing in mitigation technologies that help to secure customers from attacks even when such software updates are not deployed; and * providing customers online automated security tools, published security guidance, and security software such as firewalls, anti-virus, and other security software. The cost of these steps could reduce our operating margins. Despite these efforts, actual or perceived security vulnerabilities in our products could lead some customers to seek to return products, to reduce or delay future purchases, or to use competing products. Customers may also increase their expenditures on protecting their existing computer systems from attack, which could delay adoption of new technologies. Any of these actions by customers could adversely affect our revenue. In addition, actual or perceived vulnerabilities may lead to claims against us. Although our license agreements typically contain provisions that eliminate or limit our exposure to such liability, there is no assurance these provisions will be held effective under applicable laws and judicial decisions. We are subject to government litigation and regulatory activity that affects how we design and market our products. As a leading global software maker, we receive close scrutiny from government agencies under U.S. and foreign competition laws. Some jurisdictions also provide private rights of action for competitors or consumers to assert claims of anti-competitive conduct. For example, we have been involved in the following actions. Lawsuits brought by the U.S. Department of Justice, 18 states, and the District of Columbia in two separate actions were resolved through a Consent Decree that took effect in November 2001 and a Final Judgment entered in November 2002. These proceedings imposed various constraints on our Windows operating system businesses. These constraints include limits on certain contracting practices, mandated disclosure of certain software program interfaces and protocols, and rights for computer manufacturers to limit the visibility of certain Windows features in new PCs. Although we believe we are in full compliance with these rules, if we fail to comply with them, additional restrictions could be imposed on us that would adversely affect our business. In March 2004, the European Commission ordered us to create new versions of Windows that do not include certain multimedia technologies and to provide our competitors with specifications for how to implement certain proprietary Windows communications protocols in their own products. In September 2007, the European Court of First Instance dismissed our appeal of this ruling. The design of these special versions of Windows and the terms on which we make our protocol technology available are closely regulated by the Commission. The product design aspect of the Commission decision may limit our ability to innovate in Windows in the future, diminish the developer appeal of the Windows platform, and increase our product development costs. The availability of protocol licenses may enable competitors to develop software products that better mimic the functionality of our own products which could result in decreased sales of our products. In February 2006, the Korean Fair Trade Commission ("KFTC") issued a ruling requiring us to offer two versions of Windows PC operating systems, one with Windows Media Player and instant messaging software removed and another with those functionalities included but also including promotional links to competing software products. These remedies could adversely affect the utility and competitive position of Windows PC operating systems in Korea. Government regulatory actions and court decisions may hinder our ability to provide the benefits of our software to consumers and businesses, thereby reducing the attractiveness of our products and the revenues that come from them. New legal actions could be initiated at any time, either by these or other governments or private claimants, including with respect to new versions of Windows or other Microsoft products. The outcome of such legal actions could adversely affect us in a variety of ways, including: * We may have to choose between withdrawing products from certain geographies to avoid fines or designing and developing alternative versions of those products to comply with government rulings, which may entail removing functionality that customers want or developers rely on. * We may be required to make available licenses to our proprietary protocol technologies on terms that do not reflect their fair market value or do not protect our associated intellectual property. * If not reversed or limited on appeal, the rulings described above may be cited as a precedent in other competition law proceedings. Our software and services online offerings are subject to government regulation of the Internet domestically and internationally in many areas including user privacy, telecommunications, data protection, and online content. The application of these laws and regulations to our business is often unclear and sometimes may conflict. Compliance with these regulations may involve significant costs or require changes in business practices that result in reduced revenue. Noncompliance could result in penalties being imposed on us or orders that we stop doing the alleged noncompliant activity. Our business depends largely on our ability to attract and retain talented employees. Our business is based on successfully attracting and retaining talented employees. The market for highly skilled workers and leaders in our industry is extremely competitive. We are limited in our ability to recruit internationally by restrictive domestic immigration laws. If we are less successful in our recruiting efforts, or if we are unable to retain key employees, our ability to develop and deliver successful products and services may be adversely affected. Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution. Delays in product development schedules may adversely affect our revenues. The development of software products is a complex and time-consuming process. New products and enhancements to existing products can require long development and testing periods. Significant delays in new product releases or significant problems in creating new products could adversely affect our revenue. We make significant investments in new products and services that may not be profitable. We have made and will continue to make significant investments in research, development, and marketing for new products, services, and technologies, including Windows Vista, the 2007 Microsoft Office system, Xbox 360, Live Search, Windows Server, Zune, and Windows Live. Investments in new technology are inherently speculative. Commercial success depends on many factors including innovativeness, developer support, and effective distribution and marketing. We may not achieve significant revenue from new product and service investments for a number of years, if at all. Moreover, new products and services may not be profitable, and even if they are profitable, operating margins for new products and businesses may not be as high as the margins we have experienced historically. Adverse economic conditions may harm our business. Inflation, softness in corporate information technology spending, or other changes in general economic conditions that affect demand for computer hardware or software could adversely affect our revenue or our investment portfolio. If overall market demand for PCs, servers, and other computing devices declines significantly, or consumer or corporate spending for such products declines, our revenue will be adversely affected. In addition, our revenue would be unfavorably impacted if customers reduce their purchases of new software products or upgrades because new offerings such as Windows Vista and the 2007 Microsoft Office system are not perceived as providing significant new functionality or other value to prospective purchasers. We have claims and lawsuits against us that may result in adverse outcomes. We are subject to a variety of claims and lawsuits. Adverse outcomes in some or all of the claims pending against us may result in significant monetary damages or injunctive relief against us that could adversely affect our ability to conduct our business. Although management currently believes that resolving all of these matters, individually or in the aggregate, will not have a material adverse impact on our financial position, results of operations, or cash flows, the litigation and other claims are subject to inherent uncertainties and management’s view of these matters may change in the future. There exists the possibility of a material adverse impact on our financial position, results of operations, and cash flows for the period in which the effect of an unfavorable final outcome becomes probable and reasonably estimable. We may have additional tax liabilities. We are subject to income taxes in both the United States and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are regularly under audit by tax authorities. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. The results of an audit or litigation could have a material effect on our income tax provision, net income, or cash flows in the period or periods for which that determination is made. Our consumer hardware products may experience quality or supply problems. Our hardware products such as the Xbox 360 console are highly complex and can have defects in design, manufacture, or associated software. We could incur significant expenses, lost revenue, and reputational harm if we fail to detect or effectively address such issues through design, testing, or warranty repairs. We obtain some components of our hardware devices from sole suppliers. If a component delivery from a sole-source supplier is delayed or becomes unavailable or industry shortages occur, we may be unable to obtain replacement supplies on a timely basis, resulting in reduced sales. Either component shortages or excess inventory may require us to record charges to cost of revenue. Xbox 360 consoles are assembled in Asia; disruptions in the supply chain may result in console shortages that would affect our revenues and operating margins. If our goodwill or amortizable intangible assets become impaired we may be required to record a significant charge to earnings. Under generally accepted accounting principles, we review our amortizable intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is tested for impairment at least annually. Factors that may be considered a change in circumstances indicating that the carrying value of our goodwill or amortizable intangible assets may not be recoverable include a decline in stock price and market capitalization, reduced future cash flow estimates, and slower growth rates in our industry. We may be required to record a significant charge to earnings in our financial statements during the period in which any impairment of our goodwill or amortizable intangible assets is determined, negatively impacting our results of operations. We operate a global business that exposes us to additional risks. We operate in over 100 countries and a significant part of our revenue comes from international sales. Pressure to make our pricing structure uniform might require that we reduce the sales price of our software in the United States and other countries. Operations outside the United States may be affected by changes in trade protection laws, policies and measures, and other regulatory requirements affecting trade and investment; changes in regulatory requirements for software; social, political, labor or economic conditions in a specific country or region; and difficulties in staffing and managing foreign operations. Although we hedge a portion of our international currency exposure, significant fluctuations in exchange rates between the U.S. dollar and foreign currencies may adversely affect our net revenues. Catastrophic events or geo-political conditions may disrupt our business. A disruption or failure of our systems or operations in the event of a major earthquake, weather event, cyber-attack, terrorist attack, or other catastrophic event could cause delays in completing sales, providing services or performing other mission-critical functions. Our corporate headquarters, a significant portion of our research and development activities, and certain other critical business operations are located in the Seattle, Washington area, and we have other business operations in the Silicon Valley area of California, both of which are near major earthquake faults. A catastrophic event that results in the destruction or disruption of any of our critical business or information technology systems could severely affect our ability to conduct normal business operations and, as a result, our operating results could be adversely affected. Abrupt political change, terrorist activity, and armed conflict pose a risk of general economic disruption in affected countries, thus increasing our operating cost s. These conditions may lend additional uncertainty to the timing and budget for technology investment decisions by our customers. Acquisitions and joint ventures may have an adverse effect on our business. We expect to continue making acquisitions or entering into joint ventures as part of our long-term business strategy. These transactions involve significant challenges and risks including that the transaction does not advance our business strategy, that we don’t realize a satisfactory return on the investment we make, or that we experience difficulty in the integration of new employees, business systems, and technology, or diversion of management's attention from our other businesses. These factors could adversely affect our operating results or financial condition. Improper disclosure of personal data could result in liability and harm our reputation. We store and process significant amounts of personally identifiable information. It is possible that our security controls over personal data, our training of employees and vendors on data security, and other practices we follow may not prevent the improper disclosure of personally identifiable information. Such disclosure could harm our reputation and subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue. Our software products also enable our customers to store and process personal data. Perceptions that our products do not adequately protect the privacy of personal information could inhibit sales of our products. Other risks that may affect our business. Other factors that may affect our performance may include sales channel disruption, such as the bankruptcy of a major distributor, and our ability to implement operating cost structures that align with revenue growth. (c) STOCK REPURCHASES On July 20, 2006, we announced that our Board of Directors authorized two new share repurchase programs: a $20.0 billion tender offer that was completed on August 17, 2006 and authorization for up to an additional $20.0 billion ongoing share repurchase program that expires on June 30, 2011. Under the tender offer, we repurchased approximately 155 million shares of common stock, or 1.5% of our common shares outstanding, for approximately $3.8 billion at a price per share of $24.75. On August 18, 2006, we announced that the authorization for the $20.0 billion ongoing share repurchase program had been increased by approximately $16.2 billion. As a result, we are authorized to repurchase additional shares in an amount up to $36.2 billion through June 30, 2011. The repurchase program may be suspended or discontinued at any time without prior notice. During the first quarter of fiscal year 2008, we repurchased 80.6 million shares for $2.3 billion under the plans described in this paragraph. The transactions occu rred in open market purchases and pursuant to a trading plan under Rule 10b5-1. 22064586 29.91 22064586 14478000000 3700000 28.39 3700000 14373000000 54833400 28.88 54833400
