MICROSOFT CORPORATION

NOTES TO FINANCIAL STATEMENTS
(Unaudited)
--------------------------------------------------------------------------------

Basis of Presentation

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, as well as the
accounting changes to adopt Statement of Financial Accounting Standards (SFAS)
133, Accounting for Derivative Instruments and Hedging Activities, SFAS 141,
Business Combinations, and SFAS 142, Goodwill and Other Intangible Assets,
necessary for their fair presentation in conformity with U.S. generally accepted
accounting principles. Preparing financial statements requires management to
make estimates and assumptions that affect the reported amounts of assets,
liabilities, revenue, and expenses. Examples include provisions for returns,
concessions and bad debts, and the length of product life cycles and building
lives. Actual results may differ from these estimates. 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 Management's Discussion and
Analysis and financial statements and notes thereto included in the Microsoft
Corporation 2001 Form 10-K. Certain reclassifications have been made for
consistent presentation.

Accounting Changes

Effective July 1, 2000, Microsoft adopted SFAS 133, which establishes accounting
and reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities. The adoption
of SFAS 133 resulted in a pre-tax reduction to income of $560 million ($375
million after-tax) and a pre-tax reduction to other comprehensive income (OCI)
of $112 million ($75 million after-tax).

Effective July 1, 2001, Microsoft adopted SFAS 141 and SFAS 142. SFAS 141
requires business combinations initiated after June 30, 2001 to be accounted for
using the purchase method of accounting. It also specifies the types of acquired
intangible assets that are required to be recognized and reported separate from
goodwill. SFAS 142 requires that goodwill and certain intangibles no longer be
amortized, but instead tested for impairment at least annually. There was no
impairment of goodwill upon adoption of SFAS 142.

Net income and earnings per share for the second quarter and first six months of
fiscal 2001 adjusted to exclude amortization expense (net of taxes) is as
follows:

During the second quarter and first six months of fiscal 2002, no goodwill was
acquired, impaired, or written off. As of December 31, 2001, Desktop and
Enterprise Software and Services goodwill was $1.10 billion, Consumer Software,
Services, and Devices goodwill was $256 million, and Consumer Commerce
Investments goodwill was $151 million.

All of Microsoft's acquired intangible assets are subject to amortization. There
were no material acquisitions of intangible assets during the second quarter of
fiscal 2002. During the first six months of fiscal 2002, the Company acquired
$28 million in contract-based intangible assets, $13 million in technology-based
intangible assets, and $1 million in marketing-related and other intangible
assets, which will be amortized over approximately 3 years. No significant
residual value is estimated for these intangible assets. Intangible assets
amortization expense was $51 million for the second quarter of fiscal 2002 and
$99 million for the first six months of fiscal 2002. The components of
intangible assets were as follows:

=================================================================================================================


Amortization expense for the net carrying amount of intangible assets at
December 31, 2001 is estimated to be $90 million for the remainder of fiscal
2002, $125 million in fiscal 2003, $88 million in fiscal 2004, $38 million in
fiscal 2005, and $3 million in fiscal 2006.

Earnings Per Share

Basic earnings per share is computed on the basis of the weighted average number
of common shares outstanding. Diluted earnings per share is computed on the
basis of the weighted average number of common shares outstanding plus the
effect of outstanding put warrants using the "reverse treasury stock" method and
outstanding stock options using the "treasury stock" method.

The components of basic and diluted earnings per share were as follows:

Revenue Recognition

Revenue from products licensed to original equipment manufacturers (OEMs) has
historically been recorded when OEMs ship licensed products to their customers.
With the introduction of Windows XP in the second quarter of

--------------------------------------------------------------------------------


                                       6



fiscal 2002 and the implementation of a new internet-based system for granting
licenses to OEMs on a just in time basis, revenue for certain products is
recorded when the OEMs receive the licensed product, rather than when they ship
licensed products to their customers. The effect of this change in the second
quarter of fiscal 2002 was not material.

A portion of Microsoft's revenue is earned ratably over the product life cycle
or, in the case of subscriptions, over the period of the license agreement. End
users receive certain elements of the Company's products over a period of time.
These elements include browser technologies and technical support. Consequently,
Microsoft's earned revenue reflects the recognition of the fair value of these
elements over the product's life cycle. The percentage of revenue recognized
ratably ranges from approximately 15% to 25% of Windows desktop operating
systems and approximately 10% to 20% of desktop applications, depending on the
terms and conditions of the license and prices of the elements. Product life
cycles are currently estimated at three years for Windows operating systems and
18 months for desktop applications. The Company also sells subscriptions to
certain products via maintenance and certain organization license agreements.

At December 31, 2001, unearned revenue was $6.62 billion, compared to $5.12
billion at December 31, 2000. Desktop Applications unearned revenue was $2.88
billion, compared to $1.94 billion at December 31, 2000. Desktop Platforms
unearned revenue was $2.96 billion, compared to $2.49 billion at December 31,
2000. Enterprise Software and Services unearned revenue was $493 million,
compared to $393 million at December 31, 2000. Unearned revenue associated with
Consumer Software, Services, and Devices and Other was $287 million, compared to
$304 million a year ago.

Stockholders' Equity

The Company repurchases its common shares in the open market to provide shares
for issuance to employees under stock option and stock purchase plans. During
the December quarter, the Company repurchased 2.7 million shares of common stock
for $141 million, compared to 22.8 million shares for $1.5 billion in the
comparable quarter of the prior year. For the first six months of fiscal 2002,
the Company repurchased 24.3 million shares of common stock for $1.3 billion,
compared to 48.2 million shares of common stock for $3.2 billion in the
comparable period of the prior year. In addition, 2.6 million shares of common
stock were acquired in the second quarter of fiscal 2002 under a structured
stock repurchase transaction. The Company entered into the structured stock
repurchase transaction in fiscal 2001 and agreed to acquire 5.1 million of its
shares (half in October 2001 and half in June 2002) in exchange for an up-front

Contingencies

The Company is a defendant in U.S. v. Microsoft, a lawsuit filed by the
Antitrust Division of the U.S. Department of Justice (DOJ) and a group of
eighteen state Attorneys General alleging violations of the Sherman Act and
various state antitrust laws. After the trial, the District Court entered
Findings of Fact and Conclusions of Law stating that Microsoft had violated
Sections 1 and 2 of the Sherman Act and various state antitrust laws. A Judgment
was entered on June 7, 2000 ordering, among other things, the breakup of
Microsoft into two companies. The Judgment was stayed pending an appeal. On June
28, 2001, the U.S. Court of Appeals for the District of Columbia Circuit

--------------------------------------------------------------------------------


                                       7



affirmed in part, reversed in part, and vacated the Judgment in its entirety and
remanded the case to the District Court for a new trial on one Section 1 claim
and for entry of a new judgment consistent with its ruling. In its ruling, the
Court of Appeals substantially narrowed the bases of liability found by the
District Court, but affirmed some of the District Court's conclusions that
Microsoft had violated Section 2. On September 6, 2001, the plaintiffs announced
that on remand they will not ask the Court to break Microsoft up, that they will
seek imposition of conduct remedies, and that they will not retry the one
Section 1 claim returned to the District Court by the Court of Appeals. On
October 12, 2001, the trial court held a status conference and entered orders
requiring the parties to engage in settlement discussions until November 2,
2001. Microsoft entered into a settlement with the United States on November 2,
2001. Nine states (New York, Ohio, Illinois, Kentucky, Louisiana, Maryland,
Michigan, North Carolina and Wisconsin) agreed to settle on substantially the
same terms on November 6, 2001. Nine states and the District of Columbia
continue to litigate the remedies phase of United States v. Microsoft. The Court
will now decide whether to approve the settlement as being in the public
interest. With respect to the non-settling states remedies proceeding, the Court
has scheduled an evidentiary hearing to begin on March 11, 2002. The
non-settling States are seeking imposition of a remedy that would impose much
broader restrictions on Microsoft's business than the proposed settlement with
the Department of Justice and nine other states.

In other ongoing investigations, the DOJ and several state Attorneys General
have requested information from Microsoft concerning various issues. In
addition, the European Commission has instituted proceedings in which it alleges
that Microsoft has failed to disclose information that Microsoft competitors
claim they need to interoperate fully with Windows 2000 clients and servers and
has engaged in discriminatory licensing of such technology. The remedies sought,
though not fully defined, include mandatory disclosure of Microsoft Windows
operating system technology and imposition of fines. Microsoft denies the
European Commission's allegations and intends to contest the proceedings
vigorously.

A large number of overcharge class action lawsuits have been initiated against
Microsoft. These cases allege that Microsoft has competed unfairly and
unlawfully monopolized alleged markets for operating systems and certain
software applications and seek to recover alleged overcharges that the
complaints contend Microsoft charged for these products. Microsoft believes the
claims are without merit and is vigorously defending the cases. To date,
Microsoft has won dismissals of all claims for damages by indirect purchasers
under Federal law and in 15 separate state court proceedings. Claims on behalf
of foreign purchasers have also been dismissed. Plaintiffs have appealed most of
these rulings. While no trials or other proceedings have been held concerning
any liability issues, courts in several states have ruled that these cases may
proceed as class actions, while one court has denied class certification status
to the claims in that state proceeding. On November 20, 2001, Microsoft
announced that it and lead counsel for the Federal plaintiffs reached an
agreement to settle all of these cases. On January 11, 2002, the District Court
announced its decision not to approve the proposed settlement. The Company has
recorded a contingent liability of approximately $660 million representing
Management's estimate of the costs of resolving the contingency. The Company
intends to continue vigorously defending these lawsuits.

Netscape Communications Inc., a subsidiary of AOL-Time Warner Inc., filed an
antitrust law suit against Microsoft on January 22, 2002 in Federal court in the
District of Columbia, alleging a number of claims relating to competition with
Netscape's Navigator browser. Netscape seeks injunctive relief, treble damages
and its fees and costs. Microsoft denies these allegations and will vigorously
defend this action.

A purported class action employment discrimination case filed in October 2000 in
Federal court in Seattle, Washington against Microsoft, Donaldson v. Microsoft,
was denied class certification status by a Federal judge on November 16, 2001.
The Donaldson plaintiffs purported to represent a nationwide class of current
and former African American and female Microsoft employees and alleged that
Microsoft's compensation, evaluation, and promotion policies were discriminatory
with respect to the plaintiffs in violation of Title VII of the 1964 Civil
Rights Act and 42 U.S.C. ss. 1981. The court disagreed, finding no statistical
support for plaintiffs' allegations and held that Microsoft's managerial system
is not flawed. Following the court's ruling, the parties resolved their
differences and the case is expected to be dismissed shortly.

The Securities and Exchange Commission is conducting a non-public investigation
into the Company's accounting reserve practices. Microsoft is also subject to
various legal proceedings and claims that arise in the ordinary course of
business.

Management currently believes that resolving these matters will not have a
material adverse impact on the Company's financial position or its results of
operations.
