Cautionary Statement With Respect to Forward-Looking Statements
 
       Statements made in this annual report with respect to Sony's plans,
strategies and beliefs and other statements that are not historical facts are
forward-looking statements about the future performance of Sony which are based
on management's assumptions and belief in light of the information currently
available to it and involve risks and uncertainties. Potential risks and
uncertainties include, without limitation; general economic conditions in Sony's
markets, particularly levels of consumer spending; exchange rates, particularly
between the yen and the U.S. dollar, and other currencies in which Sony makes
significant sales or in which Sony's assets and liabilities are denominated; and
Sony's ability to continue to win acceptance of its products and services, which
are offered in highly competitive markets characterized by continual new product
introductions, rapid developments in technology (particularly in the Electronics
business), and subjective and changing consumer preferences (particularly in the
Game, Music, and Picture businesses).

Item 1.   Description of Business
 
General
 
       The Company was established in Japan in May 1946 as Tokyo Tsushin Kogyo
Kabushiki Kaisha. In January 1958, it changed its name to Sony Kabushiki Kaisha
(Sony Corporation in English).
       Sony is engaged in the development, design, manufacture, and sale of
various kinds of electronic equipment, instruments, and devices for consumer and
industrial markets. Sony's principal manufacturing facilities are located in
Japan, the U.S., Europe, and Asia, and its products are marketed by sales
subsidiaries and unaffiliated local distributors throughout the world. In
addition to internationalizing its production operations, Sony has been
promoting the transfer of research and development activities and management
functions overseas to bring its overseas operations in even closer contact with
local communities.
       Sony develops, produces, manufactures, and markets home-use game consoles
and software, mainly through Sony Computer Entertainment (SCE).
       Sony is engaged in the development, production, manufacture, and
distribution of recorded music, in all commercial formats and musical genres
worldwide, through Sony Music Entertainment Inc. (SMEI), and, in Japan, through
Sony Music Entertainment (Japan) Inc. (SMEJ).
       Sony is also engaged in the development, production, manufacture,
marketing and distribution of image-based software, including film, video,
television, and new entertainment technologies principally through Sony Pictures
Entertainment (SPE).
       In addition, Sony conducts insurance and financing business mainly in
Japan and has begun to participate in new business activities including digital
broadcasting and internet-related business mainly in Japan.
 
Products and Services
 
       Sony has adopted Statement of Financial Accounting Standards No. 131,
commencing with the fiscal year ended March 31, 1998. As a result, financial
results will now be reported using a new operating segment configuration as
described below. The prior year's results have also been reclassified, to
conform to the new presentation.
 
       Operating segment configuration is as follows:

<S>                        <C>
Electronics                Primarily divided into "Electronics" and "Game"
Entertainment              Primarily divided into "Music" and "Pictures"
Insurance and Financing    "Insurance" separated, financing business moved to
                           newly created "Other"
</TABLE>
 
       Within the Electronics segment, the previous four product category
classifications, Audio Equipment, Video Equipment, Televisions, and Other
Products have been changed to the following five product categories: "Audio",
"Video", "Televisions", "Information and communications", and "Electronic
components and other". The most significant of these changes include the removal
of game operations from Other Products to a new, independent segment entitled
Game. A new product category, Information and communications, includes computer
displays (formerly in Televisions). Also included in this new product category
are personal computers, computer peripherals, and telephones (all formerly in
Other
 
                                        3

Products). The new Electronic components and other product category includes
remaining products from the Other Products category such as semiconductors,
electronic components, and batteries.
 
       The following table sets forth Sony's sales by the operating segments and
the new product categories.

Electronics
 
       Sony's electronic products are sold throughout the world under the
trademark "Sony", which has been registered in 210 countries and territories.
       In most cases, sales of Sony's electronic products are made to
subsidiaries of the Company located in the countries and territories where
Sony's products are sold, and these subsidiaries sell to local distributors and
dealers. In some locations, the Company sells directly to local distributors.
 
      Japan:
 
              In April 1997, the Company established Sony Marketing (Japan)
     Inc., by consolidating its consumer products marketing divisions, seven
     domestic sales subsidiaries and a sales administrative subsidiary.
              In April 1998, the Company transferred most of its broadcast- and
     industrial-use electronic products marketing and sales divisions in Japan
     to Sony Marketing (Japan) Inc.
              Sony Marketing (Japan) Inc. markets Sony's consumer electronic
     products through retailers in Japan, and markets Sony's broadcast- and
     industrial-use electronic products mainly to professional and industrial
     users in Japan.
 
      North America:
 
              Sony Electronics Inc. markets Sony's electronic products for both
     consumer-use and broadcast- and industrial-use in the U.S. Sony Electronics
     Inc. has 18 sales and distribution branches and offices throughout the U.S.
     In Canada, Sony markets its electronic products through Sony of Canada Ltd.
 
      Europe:
 
              In Europe, Sony's electronic products for both consumer-use and
     broadcast- and industrial-use are marketed through 14 sales subsidiaries,
     including Sony United Kingdom Limited, Sony Deutschland G.m.b.H. and Sony
     France S.A.
 
      Other Areas:
 
              In overseas areas other than North America and Europe, Sony's
     electronic products are marketed through 22 sales subsidiaries, including
     Sony Corporation of Hong Kong Limited, Sony Gulf FZE in United Arab
     Emirates, and Sony Comercio e Industria Ltda in Brazil. In areas where the
     Company has no subsidiary, it markets its products through local
     distributors.
 
Game
 
       SCE conducts the marketing and distribution of PlayStation game consoles
and related software. This business is conducted in Japan through SCE, in the
U.S. through Sony Computer Entertainment America Inc., and in Europe through
Sony Computer Entertainment Europe Limited.
 
Music
 
       SMEI and SMEJ market and distribute CDs, MDs, DVDs, LDs, records, and
pre-recorded audio and video cassettes.
 
                                        7
<PAGE>   8
 
       SMEI conducts this business in the U.S. under the "Columbia", "Epic",
"Sony Classical", and other labels. The Columbia House Company, a 50:50
partnership between SMEI and a subsidiary of Time Warner Inc., is engaged in
direct marketing of music and home-video products in the U.S. and Canada.
       SMEI's affiliates located outside the U.S. conduct this business in
countries other than the U.S. and Japan.
 
Pictures
 
       SPE, with its global operations in 67 countries, generally secures all
rights relating to the worldwide distribution of its internally produced motion
pictures, including rights for theatrical exhibition, home videocassette, DVD,
and LD distribution, pay and free television exhibition and other markets. SPE
may also acquire distribution rights to motion pictures produced by other
companies, and these rights may be limited to particular geographic regions or
specific forms of media. SPE uses its own distribution services business for the
U.S. theatrical release of its films and those acquired from and produced by
others.
       Outside the U.S., SPE generally distributes and markets its films through
one of its Columbia Tristar Film Distributors International subsidiaries.
However, in certain countries, SPE has joint distribution facilities with other
studios or arrangements with independent local distributors.
       The worldwide home video distribution of motion pictures, television
programs, and other video products of SPE (and those acquired or licensed from
others) is handled through Columbia TriStar Home Video.
       SPE produces television programming and licenses it to U.S. network
television for prime-time or daytime broadcast and, in certain instances, for
first-run syndication or directly to cable services. SPE also licenses rights to
its library of television programming and motion pictures to network affiliates
and independent stations in the U.S. and to international television stations
and other broadcasters throughout the world.
       In addition, SPE produces original language programming in key markets
around the world in conjunction with local partners. SPE currently develops
original programming in eight languages and during the year launched the AXN
branded channel, devoted to action/adventure programming, in Asia.
 
Insurance
 
       Sony Life conducts insurance business in Japan, using qualified Life
Planner financial consultants to serve customers. As of March 31, 1998, Sony
Life employed approximately 3,700 such consultants, of whom approximately 2,300
possess the AFP (Affiliated Financial Planner) certification from the Japan
Association for Financial Planners. Sony Life maintains an extensive service
network including 94 Life Planner branch offices, 23 regional sales offices, and
1,400 independent agencies at the end of March 1998.
 
Overseas Operations
 
       Sony has actively expanded its overseas production capabilities following
a general policy that products should be manufactured in the markets in which
they are sold. During the fiscal year ended March 31, 1998, Sony set up
additional manufacturing facilities in China. As of March 31, 1998, it operated
12 manufacturing facilities in the U.S., 11 in Europe, and 35 in other areas
outside Japan. Sony intends to further expand its overseas production to build a
corporate structure less susceptible to the impact of foreign exchange rate
fluctuations. In addition to internationalizing its manufacturing
 
                                        8
<PAGE>   9
 
operations, Sony continued to promote the localization of R&D, design, materials
and parts procurement, and management functions to bring its overseas operations
in even closer contact with local communities.
 
After-Sales Service
 
       Sony provides repair and servicing functions in the countries where its
electronic products are sold. In large markets such as Japan, the U.S., and
Europe, Sony provides these services through its own service centers, authorized
independent service centers and authorized servicing dealers, and its
subsidiaries; other markets are mainly serviced by authorized servicing dealers.
       In line with industry practice, almost all of Sony's electronic products
sold in Japan carry a warranty for a period of generally one year from the date
of purchase for repairs, free of charge, for malfunctions occurring in the
course of ordinary use. In the case of broadcast- and industrial-use products,
Sony maintains support contracts with customers in addition to warranties.
Overseas warranties are generally provided for various periods of time depending
on the product and the country where it is marketed.
       To further ensure customer satisfaction, Sony maintains customer
information centers in each market.
 
Competition
 
       In each of its principal product lines, Sony encounters intense
competition throughout the world. Sony believes, however, that in the aggregate
it competes successfully and has a major position in all of the principal
product lines in which it is engaged, although the strength of its position
varies with products and markets.
       In the Electronics business, Sony believes that its attractive product
planning, the high quality of its products, its record of innovative product
introductions and product improvements, and its extensive marketing and
servicing efforts are important factors in maintaining its competitive position.
       The Game business is a historically volatile and highly dynamic industry
affected by changing technology, limited platform life cycles, hit-or-miss
software titles, seasonality, consumer spending and other economic trends.
Sony's chief competitors in the field of hardware market their own game consoles
and software titles. In the software business, development of hit titles is
increasingly challenging.
       Success in the music entertainment business is dependent to a large
extent upon the artistic and creative abilities of employees and outside talent
and is subject to the vagaries of public taste. Although SMEI is one of the
largest recorded music companies in the world, its competitive position depends
on its continuing ability to attract and develop talent that can achieve a high
degree of public acceptance. In addition, the recorded music business continues
to be adversely affected by counterfeiting, piracy, and parallel imports.
       SPE faces intense competition from other major motion picture studios
and, to a lesser extent, from independent production companies for the attention
of the movie-going public worldwide. Competition in television production,
distribution, and syndication is also intense because available broadcast time
is limited and the audience is increasingly fragmented among broadcast, cable,
and other networks both in the U.S. and internationally. In addition, SPE faces
significant long-term competition in supplying television programming from U.S.
network productions and ownership of their own television programs.
       In the insurance business, as Japan begins the deregulation of the
insurance industry through the year 2001, the marketplace will likely become
increasingly product and price competitive with more newcomers entering the
business from other industries and from outside Japan. Although Sony Life has
 
                                        9
<PAGE>   10
 
competitive strengths in products and marketing, it is impossible to predict the
impact which deregulation of the insurance market will have on Sony Life's
business.
 
Research and Development
 
       Sony actively carries out R&D at each of its internal Electronics
companies to meet the diverse product-related needs of its various businesses.
However, strategic R&D relating to Sony, particularly the development of new key
technologies, is delegated to eight corporate laboratories -- the Research
Center, the Giga Byte Laboratory, the Media Processing Laboratory, the IT
Laboratory, the Advanced Design & Production Laboratory, the EP Laboratories,
the Platform Software Development Center, the System LSI Design Center -- as
well as the D21 Laboratory and the Algorithm Research Center. As part of Sony's
R&D operations restructuring, the Platform Software Development Center was
established on February 1, 1998, the Giga Byte Laboratory and the System LSI
Design Center on June 1, 1998, and the EP Laboratories on July 1, 1998. These
facilities are located in Tokyo and Kanagawa Prefecture in Japan and are
directly controlled by corporate headquarters. The R&D areas include such fields
as electronic materials technologies, basic devices, semiconductor technologies,
software and hardware architectures for information and network products,
optical discs and magnetic recording technologies, signal processing
technologies, computer technologies, as well as long-term R&D projects.
       In the U.S., Sony has supplementary research laboratories, which
specialize in R&D fields such as digital signal processing, DTV,
telecommunications, broadcasting systems, semiconductors, and display
technology. Sony also has additional development centers in the United Kingdom,
Germany, Belgium, and Singapore.
 
       R&D expenses were 257.3 billion yen in the fiscal year ended March 31,
1996; 282.6 billion yen in the fiscal year ended March 31, 1997; and 318.0
billion yen in the fiscal year ended March 31, 1998.
       Sony believes R&D activities are vital to its long-term growth in
electronics. Through its R&D activities, Sony has recently been developing:
 
- -   "Super Audio CD," a next generation music carrier based on Direct Stream
    Digital (DSD) which was co-developed with Philips Electronics. N.V. This is
    a new, high resolution digital encoding system that allows music recording
    of unprecedented quality.
 
- -   "AMInet (Advanced Multimedia Information Network)," a next-generation
    Internet architecture which maintains compatibility with current internet
    technology, for real-time transmission of continuous media and high-speed
    bulk data. AMInet was co-developed with Nippon Telegraph and Telephone
    Corporation and Keio University.
 
- -   "HiFD (High Capacity Floppy Disk)," a new 3.5-inch floppy disk system with a
    substantially more storage capacity than the current 3.5-inch floppy disk.
    HiFD drives will also be able to read from and write to existing 3.5-inch
    floppy disks (2DD/2HD). HiFD was co-developed with Fuji Photo Film Co., Ltd.

Patents and Licenses
 
       Sony has a number of patents in Japan and other countries, and licenses
granted from other firms. Sony considers a number of its license agreements to
be important to its business. Sony has license agreements with RCA Thomson
Licensing Corporation covering a wide range of its products, such as color
televisions, VTRs, and other related equipment. Sony has license agreements with
Lucent Technologies Inc. covering semiconductors and has cross license
agreements with Philips Electronics N.V. covering optical disc players and VTRs.
Sony also has license agreements with Matsushita Electric Industrial Co., Ltd.
and Victor Company of Japan Limited covering magnetic and optical recorder
products, Ampex Corporation covering video tape recorder related products, and
International Business Machines Corporation covering a wide range of information
processing products.
 
Sources of Supply
 
       Sony has been pursuing optimum procurement of raw materials, parts, and
components to be used in the production of its products on a global basis. These
items are purchased from various suppliers around the world. Generally, Sony
maintains multiple suppliers for every category of parts and components.
 
Employee Relations
 
       As of March 31, 1998, Sony had approximately 173,000 employees, of which
approximately 16% were members of labor unions. Approximately 69,000 employees
were located in Japan and 104,000 overseas. Sony considers its labor relations
to be very good.

Item 3.   Legal Proceedings
 
       In August 1998, the Securities and Exchange Commission issued a settled
cease-and-desist order which found that the Company had violated certain
periodic reporting requirements of the federal securities laws by making
inadequate disclosure concerning (i) Sony Pictures' net losses prior to the
quarter ended September 30, 1994 and (ii) the impact of those losses on the
Company's consolidated results for the fiscal year ended March 31, 1994 and the
quarter ended June 30, 1994. The Order also found that a former director, who
was at the time the General Manager of the Company's Capital Markets & Investor
Relations Division, was a cause of the Company's violations. The Order, to which
the Company and the former director consented without admitting or denying the
matters set forth therein, requires (i) an independent auditor to examine and
issue a written opinion on the Company's MD&A presentation for the fiscal year
ending March 31, 1999; (ii) the Company's Chief Financial Officer to ensure that
the Company's public financial disclosures comply with applicable requirements;
and (iii) compliance with applicable segment reporting requirements. In a
parallel civil action by the Commission, the Company, without admitting or
denying the allegations in the action, also consented to payment of a civil
penalty of 1 million U.S. dollars.
 
       On or about July 23, 1996, SMEI was served with an antitrust civil
investigation demand from the Office of the Attorney General of the State of
Florida seeking the production of documents in connection with an investigation
to determine whether there "is, has been or may be" a "conspiracy to fix the
prices" of compact discs ("CDs") or conduct consisting of "unfair methods of
competition" or "unfair trade practices" in the sale and marketing of CDs. No
allegations of unlawful conduct have been made against SMEI. By letter dated
January 8, 1998, SMEI was notified by the Office of the Attorney General of the
State of Florida that certain documents that SMEI had produced to its office
were shared under a confidentiality provision in the Florida statutes with the
Office of the Attorney General of the State of Illinois and the Office of the
Attorney General of the State of New York. To date, no action has been taken by
the Attorneys General of these states.
 
       By letter dated April 11, 1997, the Federal Trade Commission ("FTC")
advised SMEI of the existence of a preliminary investigation to determine
whether minimum advertised pricing programs used by major record distributors
constitute an unfair method of competition in violation of Section 5 of the
Federal Trade Commission Act. SMEI received a subpoena dated September 19, 1997
for the production of documents in connection with that investigation.
 
       On May 30, 1995, a purported class action was filed with the United
States District Court for the Central District of California, entitled Digital
Distribution Inc. d/b/a Compact Disc Warehouse v. CEMA Distribution, Sony Music
Entertainment, Inc., Warner Elektra Atlantic Corporation, UNI Distribution
Corporation, Bertelsmann Music Group, Inc. and PolyGram Group Distribution,
Inc., No. 95-3536. The plaintiff, representing a class of direct purchasers of
recorded music CDs, alleged that defendants violated the federal antitrust laws
by engaging in a conspiracy to fix the prices of CDs, and sought an injunction
and treble damages. On January 9, 1996, the defendants' motion to dismiss the
amended complaint was granted and the action was dismissed, with prejudice.
Plaintiff appealed the dismissal to the United States Court of Appeals for the
Ninth Circuit, No. 96-55264. On July 3, 1997, the United States Court of Appeals
for the Ninth Circuit reversed the dismissal of the amended complaint and
remanded the case to the District Court, holding that the amended complaint was
sufficient to meet the pleading requirements of the Federal Rules of Civil
Procedure and that the action should proceed. On October 29, 1997, the District
Court stayed proceedings in the action due to the filing on May 12, 1997 of a
Chapter 7 Petition under the U.S. Bankruptcy Code by plaintiff. After
 
                                       15
<PAGE>   16
 
further proceedings in the bankruptcy court on the part of plaintiff, the Court
lifted the stay and restored the matter to the docket. On August 25, 1998, SMEI
answered the amended complaint, denying its material allegations, asserting
affirmative defenses and demanding judgment against the plaintiffs.
 
       On September 30, 1997, a purported class action was commenced in the
United States District Court for the Central District of California entitled
Chandu Dani d/b/a Compact Disc Warehouse and Record Revolution v. EMI Music
Distribution, Inc., Sony Music Entertainment, Inc., Warner Elektra Atlantic
Corporation, Universal Music and Video Distribution, Bertelsmann Music Group,
Inc. and PolyGram Group Distribution, Inc., No. 97-7226. On October 16, 1997,
plaintiffs filed a first amended complaint. Plaintiffs, purporting to represent
a class of direct purchasers of CDs, allege that defendants violated the federal
and state antitrust laws by engaging in a conspiracy to fix the prices of CDs
and seek an injunction and treble damages. On December 22, 1997, SMEI answered
the amended complaint, denying its material allegations, asserting affirmative
defenses and demanding judgment against the plaintiffs.
 
       On October 21, 1997, an individual action was commenced in the United
States District Court for the Southern District of New York, entitled T. Obie,
Inc., d/b/a Chestnut Hill Company Disc v. EMI Music Distribution, Sony Music
Entertainment, Inc., Warner Elektra Atlantic Corporation, Universal Music and
Video Distribution, Bertelsmann Music Group, Inc. and PolyGram Group
Distribution, Inc., No. 97 Civ. 7764. The claims asserted are substantially the
same as those asserted in the Chandu Dani action. On January 16, 1998, SMEI
answered the complaint, denying its material allegations of the complaint,
asserting affirmative defenses and demanding judgment against plaintiffs.
 
       On December 2, 1997, a purported class action was commenced in the United
States District Court for the Central District of California entitled Third
Street Jazz and Rock Holding Corporation v. EMI Music Distribution, Inc., Sony
Music Entertainment Inc., Warner Elektra Atlantic Corporation, Universal Music
and Video Distribution, Bertelsmann Music Group, Inc. and PolyGram Group
Distribution, Inc., No. 97-8864. The claims asserted are substantially the same
as those asserted in the Chandu Dani action reported above. On January 20, 1998,
SMEI answered the complaint, denying its material allegations, asserting
affirmative defenses and demanding judgment against plaintiffs.
 
       On January 28, 1998, a purported class action was commenced in the United
States District Court for the Southern District of New York, entitled Nathan
Muchnick, Inc., v. Sony Music Entertainment, Inc., PolyGram Group Distribution,
Inc., Universal Music and Video Distribution, Warner Elektra Atlantic
Corporation and EMI Music Distribution, No. 98 Civ. 0612. The claims asserted
are substantially the same as those asserted in the Chandu Dani action reported
above. On February 23, 1998, SMEI answered the complaint, denying its
allegations, asserting affirmative defenses and demanding judgments against
plaintiffs.
 
       In April, 1998, the Judicial Panel on Multidistrict Litigation ("JPML")
directed that the Chandu Dani, Third Street Jazz, T. Obie and Nathan Muchnick
actions be coordinated for pretrial proceedings and assigned the coordinated
case to the United States District Court for the Central District of California.
In August, 1998, plaintiffs' counsel asked the JPML to add the Digital action to
the coordinated proceedings as a "Tag along" action.
 
       On February 17, 1998, a purported class action was commenced in the
Circuit Court of Cocke County, Tennessee at Newport, entitled Ottinger &
Silvery, et al. v. EMI Music Distribution, Inc., Sony
 
                                       16
<PAGE>   17
 
Music Entertainment, Inc., Warner Elektra Atlantic Corporation, UNI Distribution
Corporation, Bertelsmann Music Group, Inc. and PolyGram Group Distribution, Inc.
The action is brought on behalf of persons who from January 29, 1993 to the
present purchased CDs indirectly from the defendants in Alabama, Arizona,
California, the District Court of Columbia, Florida, Kansas, Maine, Michigan,
Minnesota, Mississippi, New Mexico, North Carolina, North Dakota, South Dakota,
Tennessee, West Virginia and Wisconsin, and alleges that the defendants are
engaged in a conspiracy to fix the prices of CDs, in violation of antitrust,
unfair trade practices and consumer protection statutes of each of those
jurisdictions. On May 11, 1998, SMEI and all of the other defendants moved to
dismiss the action.
 
       On October 24, 1996, the Italian Competition and Market Commission (the
"ICMC") commenced an investigation against Warner Music Italia S.p.A., PolyGram
Italia S.r.l., EMI Music Italy S.p.A., BMG Ricordi S.p.A., Sony Music
Entertainment S.p.A. and the Italian Music Industry Federation regarding prices
of CDs sold in Italy by those companies. On October 9, 1997, the ICMC issued an
administrative decision concluding, in part, that those record companies had
agreed on a uniform commercial structure for CDs sold to dealers. The ICMC
imposed monetary sanctions on each of the record companies identified above,
including a penalty against Sony Music Entertainment S.p.A. in the amount of
1,495,952,000 Italian Lira. Each of the record companies has appealed the ICMC's
order to the Regional Administrative Court of Lazio and the appeal remains
pending.
 
       In addition, the Company and certain of its subsidiaries are defendants
in several ongoing and pending lawsuits. However, based upon the information
currently available to both the Company and its legal counsel, management of the
Company believes that damages from such lawsuits, if any, would not have a
material effect on the Company's consolidated financial position.

       The primary markets for the Company's Common Stock are the Tokyo Stock
Exchange (the "TSE") in the form of Common Stock and the New York Stock Exchange
(the "NYSE") in the form of American Depositary Shares evidenced by American
Depositary Receipts ("ADRs"). Each American Depositary Share represents one

listed on the NYSE since 1970. The Company's ADRs are issued and exchanged by
Morgan Guaranty Trust Company of New York, as Depositary.
 
       At March 31, 1998, there were 407,195,271 shares of Common Stock
outstanding, of which 17,390,505 shares were in the form of ADRs and 56,613,393
shares were held of record in the form of Common Stock by residents in the U.S.
The number of registered ADR holders was 7,139 and the number of registered

Item 6.   Exchange Controls and Other Limitations Affecting Security Holders
 
(a) Japanese Foreign Exchange Controls
 
       Effective from April 1, 1998, the Foreign Exchange and Foreign Trade
Control Law was amended and the title of the statute was changed to the Foreign
Exchange and Foreign Trade Law. Under the amended Law, all aspects of
regulations on foreign exchange and foreign trade transactions which were
subject to licensing or other approval or prior notification requirements are,
with minor exception relating to certain inward direct investment (which is not
applicable to the Company's shares), now subject to the post facto reporting
requirements. However, the Minister of Finance has the power to impose a
licensing requirement for certain transactions in limited circumstances.
 
(b) Description of Common Stock
 
       Set forth below is certain information relating to the Common Stock of
the Company, including brief summaries of certain provisions of the Company's
Articles of Incorporation and Shares Handling Regulations, as currently in
effect, and of the Commercial Code of Japan relating to a joint stock company
(Kabushiki Kaisha) and certain related legislation.
 
General
 
       The presently authorized capital stock of the Company is 1,350,000,000
shares, which may be issued with a par value or without a par value. The
Commercial Code requires that shares be in registered form. Under the Commercial
Code shares are transferable by delivery of share certificates, but in order to
assert shareholders' rights against the Company, the transferee must have his
name registered in the Company's register of shareholders. All of the presently
outstanding shares of the Company are of a par value of 50 yen per share. The
Company may, by a resolution of the Board of Directors, convert par value shares
into non-par value shares or vice versa. Shareholders are required to file their
names, addresses and seals with The Toyo Trust and Banking Company, Limited, the
transfer agent for the Company's Common Stock, and shareholders not resident in
Japan are required to file a mailing address in Japan or appoint a resident
proxy in Japan; these requirements do not apply to the holders of ADRs.
 
       The central clearing system of share certificates under the Law
Concerning Central Clearing of Share Certificates and Other Securities of Japan
applies to the shares of Common Stock of the Company. Pursuant to this system a
holder of shares of Common Stock is able to choose, at his discretion, to
participate in this system and all certificates of shares of Common Stock
elected to be put into this system are deposited with the central clearing
system and all such shares are registered in the name of the clearing house in
the Company's register of shareholders. Each participating shareholder is in
turn registered in the register of beneficial shareholders and treated the same
way as shareholders registered in the Company's register of shareholders.
 
Dividends
 
       The Articles of Incorporation of the Company provide that the accounts
shall be closed on March 31 of each year and that dividends, if any, shall be
paid to the shareholders of record as of the end of such day. After the close of
the fiscal period, the Board of Directors prepares, among other things, a
proposed allocation of profits for dividends and other purposes; this proposal
is submitted to the Statutory Auditors of the Company and to independent
certified public accountants and then submitted for approval to the
 
                                       19
<PAGE>   20
 
ordinary general meeting of shareholders, which is normally held in June each
year. In addition to provisions for dividends, if any, and for the legal reserve
and other reserves, the allocation of profits customarily includes a bonus to
Directors and Statutory Auditors. In addition to annual dividends, the Board of
Directors of the Company may by its resolution declare a cash distribution
pursuant to Article 293-5 of the Commercial Code (an "interim dividend") to
shareholders who are registered in the Company's register of shareholders at the
end of each September 30, subject to the limitations described below.
 
       The Commercial Code provides that a company may not make any distribution
of profits by way of dividends or interim dividends for any fiscal year unless
it has set aside in its legal reserve an amount equal to at least one-tenth of
the amount paid by way of appropriation of retained earnings for such fiscal
period until the legal reserve is one-quarter of its stated capital. Under the
Commercial Code the Company is permitted to distribute profits by way of
year-end or interim dividends out of the excess of its net assets over the
aggregate of (i) its stated capital, (ii) its additional paid-in capital, (iii)
its accumulated legal reserve, (iv) the legal reserve to be set aside in respect
of the fiscal period concerned, and (v) the excess, if any, of unamortized
expenses incurred in preparation for commencement of business and in connection
with research and development expense over the aggregate of amounts referred to
in (ii), (iii) and (iv) above. If the Company has on its balance sheet a number
of shares of its Common Stock which the Company has acquired for the purpose of
transferring the same to its Directors and/or employees but such shares are yet
to be so transferred, the book value of such shares shall be deducted from the
amount available for payment of dividends. In the case of interim dividends, the
net assets are calculated by reference to the balance sheet as at the last
closing of the Company's accounts, but adjusted to reflect any subsequent
payment by way of appropriation of retained earnings and transfer to legal
reserve in respect thereof, provided that interim dividends may not be paid
where there is a risk that at the end of the fiscal year there might not be any
excess of net assets over the aggregate of the amounts referred to in (i), (ii),
(iii), (iv) and (v) above, and, in addition to the deduction referred to in the
immediately preceding sentence, if the Company's shareholders have adopted a
resolution for the Company's purchase of shares of its Common Stock for the
purpose of transferring the same to its Directors and/or employees or for the
purpose of retiring the same with retained earnings, the total amount of
purchase price authorized by such resolution shall, so long as such resolution
has not expired, and whether or not such purchase has been effected, be deducted
from the amount available for interim dividends.
 
       The Commercial Code, currently in effect, does not provide for "stock
dividends". However, under the Code, shareholders may by resolution transfer any
amount which is distributable as dividends to stated capital and the Board of
Directors may by resolution issue additional shares by way of a stock split up
to the aggregate par value equal to the amount so transferred; thus, the same
effect as a stock dividend can be achieved.
 
       In Japan the "ex-dividend" date and the record date for dividends precede
the date of determination of the amount of the dividend to be paid.
 
                                       20
<PAGE>   21
 
Transfer of Additional Paid-in Capital and Legal Reserve to Stated Capital and
Stock Splits (Free Share Distributions)
 
       When the Company issues new shares of Common Stock, the entire amount of
the issue price of such new shares is required to be accounted for as stated
capital, although the Company may account for an amount not exceeding one-half
of such issue price as additional paid-in capital (subject to the remainder
being not less than the total par value of the new shares being issued). The
Board of Directors may transfer the whole or any part of additional paid-in
capital and legal reserve to stated capital and grant to shareholders additional
shares of Common Stock free of charge by way of a stock split, without affecting
the par value thereof, with reference to the whole or any part of the amount of
additional paid-in capital and legal reserve so transferred to stated capital;
such additional shares may also be granted by reference to the amount
representing the portion of the issue price of shares of Common Stock in excess
of the par value thereof which has been accounted for as stated capital.
 
       The Commercial Code permits the Company to make a partially free
distribution to shareholders by way of a rights issue at a subscription price
per share which is less than the par value thereof if (a) the difference between
the subscription price and the par value does not exceed the amount of the
stated capital minus the aggregate par value of all outstanding shares, divided
by the number of new shares to be issued pursuant to such rights issue, (b) the
sum of the net assets of the Company (as appearing on the latest balance sheet)
and the total subscription price, divided by the number of the shares
outstanding immediately after the issue of the new shares, is at least 50 yen
and (c) the subscription rights are made transferable. In order to satisfy the
requirement mentioned in (a) above, the Board of Directors may transfer the
whole or any part of additional paid-in capital or legal reserve to stated
capital.
 
General Meeting of Shareholders
 
       The ordinary general meeting of shareholders to settle accounts of the
Company for each fiscal period is normally held in June each year in
Shinagawa-ku, Tokyo, Japan. In addition, the Company may hold an extraordinary
general meeting of shareholders whenever necessary by giving at least two weeks'
advance notice to shareholders.
 
       Notice of a shareholders' meeting setting forth the place, time and
purpose thereof, must be mailed to each shareholder having voting rights (or, in
the case of a non-resident shareholder, to his resident proxy or mailing address
in Japan) at least two weeks prior to the date set for the meeting.
 
       Any shareholder holding at least 300 units of shares or 1% of the total
number of outstanding shares for six months or more may propose a matter to be
considered at a general meeting of shareholders by submitting a written request
to a Representative Director at least six weeks prior to the date set for such
meeting.
 
Voting Rights
 
       A shareholder is entitled to one vote per share subject to the
limitations on voting rights set forth in the following paragraph and " "Unit"
Share System -- Voting rights of a holder of shares representing less than one
unit" below. Except as otherwise provided by law or by the Company's Articles of
Incorporation, a resolution can be adopted at a general meeting of shareholders
by a majority of the shares having voting rights represented at the meeting. The
Commercial Code and the Company's Articles of Incorporation provide, however,
that the quorum for the election of Directors and Statutory Auditors shall
 
                                       21
<PAGE>   22
 
not be less than one-third of the total number of outstanding shares having
voting rights. The Company's shareholders are not entitled to cumulative voting
in the election of Directors. A corporate shareholder, more than one-quarter of
whose outstanding shares are directly or indirectly owned by the Company, may
not exercise its voting rights in respect of the shares of the Company. The
Company has no voting rights with respect to its own Common Stock. Shareholders
may exercise their voting rights through proxies provided that the proxies are
also shareholders holding voting rights. The Company's shareholders also may
cast their votes in writing.
 
       The Commercial Code provides that in order to amend the Articles of
Incorporation and in certain other instances, including an increase in the total
number of shares authorized to be issued, a reduction of the stated capital, the
removal of a Director or Statutory Auditor, dissolution, merger (with an
exception of the merger of a small company) or consolidation of a corporation,
the transfer of the whole or an important part of the business, the taking over
of the whole of the business of any other corporation, any offering of new
shares at a "specially favorable" price (or any offering of convertible bonds or
debentures with "specially favorable" conversion conditions or of bonds or
debentures with warrants or rights to subscribe for new shares with "specially
favorable" conditions) to persons other than shareholders or granting to
Directors and/or employees rights to subscribe for new shares, the quorum shall
be a majority of the total number of shares having voting rights outstanding and
the approval of the holders of at least two-thirds of the shares having voting
rights represented at the meeting is required (the "special shareholders
resolution").
 
Subscription Rights
 
       Holders of the Company's Common Stock have no pre-emptive rights under
its Articles of Incorporation. Authorized but unissued shares may be issued at
such times and upon such terms as the Board of Directors determines, subject to
the limitations as to the offering of new shares at a "specially favorable"
price mentioned above. The Board of Directors may, however, determine that
shareholders shall be given subscription rights regarding a particular issue of
new shares, in which case such rights must be given on uniform terms to all
shareholders as at a record date of which not less than two weeks' public notice
must be given. Each of the shareholders to whom such rights are given must also
be given notice of the expiry thereof at least two weeks prior to the date on
which such rights expire.
 
       Rights to subscribe for new shares may be made generally transferable by
the Board of Directors. Whether the Company will make subscription rights
generally transferable in future rights offerings will depend upon the
circumstances at the time of such offerings. If subscription rights are not made
generally transferable, transfers by a non-resident of Japan or a corporation
organized under the laws of a foreign country or whose principal office is
located in a foreign country will be enforceable against the Company and third
parties only if the Company's prior written consent to each such transfer is
obtained. When such consent is necessary in the future for the transfer of
subscription rights, the Company intends to consent, on request, to all such
transfers by such a non-resident or foreign corporation.
 
       The 1997 amendments to the Commercial Code permit a company to provide in
its articles of incorporation that it may, by a special shareholders resolution,
grant to its directors and/or employees rights to subscribe for new shares if
there exists a justifiable reason. The Company has provided such a provision in
its Articles of Incorporation by amending them in June 1998, and, therefore,
may, if there exists a justifiable reason, by a special shareholders resolution
(which is effective for one year) grant to its Directors and/or employees rights
to subscribe for new shares (in aggregate (together with the number of shares
issuable upon exercise of all outstanding subscription rights which have been
granted to Directors
 
                                       22
<PAGE>   23
 
and/or employees, if any) not more than 10% of the total issued and outstanding
shares) to particular Directors and/or employees designated by such resolution,
which rights may be made exercisable not more than ten years from the resolution
in accordance with the terms approved by the resolution. Such special
shareholders resolution cannot be taken if shareholders have already adopted a
resolution for repurchase by the Company of its shares for the purpose of
transferring the same to its Directors and/or employees by way of a stock option
and any such stock option is outstanding unexercised. No such special
shareholders resolution has yet been taken by the Company's shareholders.
 
Dilution
 
       In the future it is possible that market conditions and other factors
might make a rights offering to shareholders at par or substantially below the
market price of shares of Common Stock desirable. If the number of shares
offered in a rights offering is substantial in relation to the number of shares
outstanding and the market price exceeds the subscription price at the time of
the offering, a shareholder who does not exercise and is unable otherwise to
realize the full value of his subscription rights would suffer economic dilution
of his equity interest in the Company. If the rights to subscribe for new shares
are granted to the Company's Directors and/or employees which rights are
exercisable at a price below the market price of the shares and the number of
shares issuable upon such exercise is substantial, existing shareholders' equity
interest in the Company will be diluted.
 
Liquidation Rights
 
       In the event of a liquidation of the Company, the assets remaining after
payment of all debts and liquidation expenses and taxes will be distributed
among the shareholders in proportion to the respective numbers of shares held.
 
Liability to Further Calls or Assessments
 
       All the Company's presently outstanding shares of Common Stock including
shares represented by the American Depository Shares are fully paid and
non-assessable.
 
Transfer Agent
 
       The Toyo Trust and Banking Company, Limited is the transfer agent for the
Company's Common Stock; as such transfer agent, it keeps the Company's register
of shareholders in its office at 10-11, Higashisuna 7-chome, Koto-ku, Tokyo,
Japan, and makes transfer of record ownership upon presentation of the
certificates representing the transferred shares.
 
Record Date
 
       March 31 is the record date for the Company's year-end dividends. The
shareholders who are registered as the holders of 100 shares or more in the
Company's register of shareholders at the end of each March 31 are also entitled
to exercise shareholders' rights at the ordinary general meeting of shareholders
with respect to the fiscal period ending on such March 31. September 30 is the
record date for interim dividends. In addition, the Company may set a record
date for determining the shareholders entitled to other rights and for other
purposes by giving at least two weeks' public notice.
 
                                       23
<PAGE>   24
 
       The price of the shares generally goes ex-dividend or ex-rights on
Japanese stock exchanges on the third business day prior to a record date (or if
the record date is not a business day, the fourth business day prior thereto),
for the purpose of dividends or rights offerings.
 
Repurchase by the Company of its Common Stock
 
       Except as otherwise permitted by the Commercial Code and the Law of
Special Exception to the Commercial Code Concerning Retirement of Shares enacted
in 1997 (the "Special Retirement Law") as set out below, the Company or any of
its subsidiaries cannot acquire the Company's Common Stock except by means of a
reduction of capital in the manner provided in the Commercial Code. The Company
may acquire its Common Stock in response to a shareholder's request for purchase
of his shares representing less than one unit. See " "Unit" Share
System -- Right of a holder of shares representing less than one unit to require
the Company to purchase such shares" below. Shares so purchased must be sold or
otherwise transferred to a third party within a reasonable period thereafter.
 
       The 1994 and 1997 amendments to the Commercial Code and the Special
Retirement Law enable the Company to acquire its Common Stock for the following
purposes, subject to the authorization of shareholders at an ordinary general
meeting (if the Articles of Incorporation provide that the shares may be
purchased for the purpose of retirement by resolution of the Board of Directors
if the Board deems it especially necessary to do so in view of general economic
condition, the business and financial condition of the Company and other
factors, by the resolution of the Board of Directors): (1) for the purpose of
transferring the same to its Directors and/or employees if there exists a
justifiable reason; and (2) for the purpose of retirement thereof with retained
earnings. Acquisition by the Company of shares of its Common Stock for the above
purposes is subject to, among other things, the following restrictions: (a) the
number of shares to be acquired may not exceed 10% of all issued and outstanding
shares (except in the case of purchase of shares for retirement pursuant to
shareholders' authorization); (b) total amount of purchase price may not exceed
the amount of the retained earnings available for dividend payment minus the
amount to be paid by way of appropriation of retained earnings for the fiscal
year and, if any amount of retained earnings is to be capitalized, such amount
(if the purchase is made pursuant to the resolution of the Board of Directors as
referred to in the parentheses above, one-half of such permitted amount); and
(c) acquisition shall be made through a stock exchange transaction or by way of
tender offer. No such acquisition pursuant to a resolution of the Board of
Directors may be made after the conclusion of the ordinary general meeting of
shareholders for the fiscal year ending immediately after the Board resolution.
The Company's shareholders have not given an authorization for the acquisition
of shares pursuant to (1) above. In June 1997, the Company amended its Articles
of Incorporation providing for the authority for the Company to purchase shares
of its Common Stock not exceeding 30,000,000 shares by resolution of the Board
of Directors for the purpose of retirement thereof with retained earnings. No
Board resolution has been made for this purpose.
 
       The Special Retirement Law was amended in March 1998 enabling the Company
to acquire its own shares for the purpose of retiring the same with additional
paid-in capital by resolution of the Board of Directors if the Articles of
Incorporation so provide and if the Board deems it especially necessary to do so
in view of general economic condition, the business and financial condition of
the Company and other factors. On June 26, 1998, the Company amended its
Articles of Incorporation providing for the authority for the Company to
purchase shares of its Common Stock not exceeding 30,000,000 shares with the
total purchase price not exceeding 400 billion yen by resolution of the Board of
Directors for the purpose of retiring the same with additional paid-in capital.
The acquisition of shares under this authorization is subject to the restriction
that (x) the total amount of the purchase price may not exceed
 
                                       24
<PAGE>   25
 
the total amount of additional paid-in capital and accumulated legal reserve
minus the amount equal to one-fourth of stated capital, and (y) if the aggregate
of the amounts of (i) through (v) referred to under "Dividends" above and the
amount of interim dividend distributed exceeds the net assets appearing on the
balance sheets as at the latest closing of the Company's accounts, no purchase
of shares for this purpose can be made. No Board resolution has been taken for
this purpose.
 
"Unit" Share System
 
Pursuant to the Commercial Code the Company has adopted 100 shares as one unit
of shares.
 
      Transferability of shares representing less than one unit
 
        Certificates for shares representing less than one unit may only be
     issued in certain limited circumstances. Since the transfer of shares
     normally requires delivery of the certificates therefor, fractions of a
     unit for which no share certificates are issued are not transferable.
     Shares representing less than one unit for which share certificates have
     been issued continue to be transferable, but the transfer may be registered
     in the Company's register of shareholders only if the transferee is already
     a registered shareholder (whether in respect of units or of shares
     representing less than one unit).
 
      Right of a holder of shares representing less than one unit to require the
Company to purchase such
     shares
 
        A holder of shares representing less than one unit may at any time
     require the Company to purchase such shares at their last reported sale
     price on the Tokyo Stock Exchange on the day when such request is made or,
     if no sale takes place on the Tokyo Stock Exchange on such day, the price
     at which the first sale of the shares is effected on the Tokyo Stock
     Exchange thereafter, less applicable brokerage commission. The usual
     securities transfer tax is applicable to such transactions.
 
      Other rights of a holder of shares representing less than one unit
 
        A holder of shares representing less than one unit has the following
     rights in respect of such shares: (i) the right to receive dividends
     (including interim dividends), (ii) the right to receive shares and/or cash
     by way of a stock split or upon consolidation or subdivision of shares or
     upon a capital decrease or merger of the Company, (iii) the right to be
     allotted subscription rights with respect to new shares, convertible bonds
     and bonds with warrants to subscribe for shares when such rights are
     granted to shareholders, (iv) the right to participate in the distribution
     of surplus assets in the event of the liquidation of the Company, and (v)
     the right to require the Company to issue replacement share certificates
     for lost, stolen or destroyed share certificates. All other rights,
     including voting rights, cannot be exercised with respect to shares
     representing less than one unit.
 
      Voting rights of a holder of shares representing less than one unit
 
        A holder of shares representing less than one unit cannot exercise any
     voting rights with respect to such shares. In calculating the quorum for
     various voting purposes, the aggregate number of shares representing less
     than one unit will be excluded from the number of outstanding shares. A
     holder of shares representing one or more whole units will have one vote
     for each such share, except as stated in "Voting Rights" above.
 
                                       25
<PAGE>   26
 
      Consolidation by operation of law of shares constituting one unit into one
share
 
        The unit share system is intended to be an interim measure with a view
     ultimately to achieve shares of a much higher denomination than at present.
     On a date to be specified by separate legislation, the shares comprising
     one unit will be deemed to be consolidated into one share. Presently it is
     not known when the bill specifying such date will be submitted to the
     Japanese parliament. If the consolidation takes place, the holder of any
     fractional share constituting one-hundredth of one share or any integral
     multiple thereof, which may result from such consideration, will be
     registered as the holder thereof in the register of fractional shares and
     the holder of any fraction representing less than a whole hundredth of one
     share will be entitled to receive a cash payment.
 
(c) Reporting of Substantial Shareholdings
 
       The Securities and Exchange Law of Japan, as amended, requires any person
who has become, beneficially and solely or jointly, a holder of more than 5% of
the total issued shares of a company listed on any Japanese stock exchange or
whose shares are traded on the over-the-counter market in Japan to file with the
Minister of Finance within five business days a report concerning such
shareholdings.
 
       A similar report must also be made in respect of any subsequent change of
1% or more in any such holding. For this purpose, shares issuable to such person
upon conversion of convertible securities or exercise of share subscription
warrants are taken into account in determining both the number of shares held by
such holder and the issuer's total issued share capital. Copies of each such
report must also be furnished to the issuer of such shares and all Japanese
stock exchanges on which the shares are listed or (in the case of shares traded
over-the-counter) the Japan Securities Dealers Association.
 
Item 7.   Taxation
 
       Generally, a non-resident of Japan or a non-Japanese corporation is
subject to Japanese withholding tax on dividends paid by a Japanese corporation.
Stock splits in themselves (whether for the purpose of making a free
distribution or dividend in shares), subject as set out below, are not subject
to Japanese income tax. However, a transfer of retained earnings or legal
reserve (but not additional paid-in capital) to stated capital is treated as a
dividend payment to shareholders for Japanese tax purposes and is, in general,
subject to Japanese income tax.
       Under the Income Tax Convention between the U.S. and Japan (the
"Convention"), the maximum rate of Japanese withholding tax that may be imposed
on dividends paid to a U.S. resident or corporation not having a "permanent
establishment" (as defined therein) in Japan is generally 15%.
       For purposes of the Convention and the U.S. Internal Revenue Code of
1986, as amended (the "Code"), U.S. holders of ADRs will be treated as the
owners of the Common Stock underlying the American Depositary Shares evidenced
by the ADRs. For purpose of this discussion, a "U.S. holder" is a holder that
(i) is a resident of the United States for purposes of the Convention, (ii) does
not maintain a permanent establishment or fixed base in Japan to which ADRs or
Common Stock are attributable and through which the beneficial owner carries on
or has carried on business (or in the case of an individual, performs or has
performed independent personal services) and (iii) who is not otherwise
ineligible for benefits under the Convention with respect to income and gain
derived in connection with the ADRs or Common Stock.
 
                                       26
<PAGE>   27
 
Japanese Taxation of Common Stock or ADRs
 
       In the absence of an applicable tax treaty, convention or agreement
reducing the maximum rate of withholding tax, the rate of Japanese withholding
tax on dividends paid by Japanese corporation to non-residents of Japan or
non-Japanese corporation is 20%.
       Gains derived by a non-resident of Japan or a non-Japanese corporation
from the sale of Common Stock or ADRs outside Japan, or from the sale of Common
Stock within Japan by a non-resident of Japan or by a non-Japanese corporation
not having a permanent establishment in Japan, are in general not subject to
Japanese income or corporation tax. Japanese inheritance or gift tax at
progressive rates may be payable by an individual who has acquired Common Stock
or ADRs as a legatee, heir or donee.
       If the Company purchases shares of its Common Stock by way of a tender
offer for the purpose of retirement with retained earnings as described under
"Item 6. Exchange Controls and Other Limitations Affecting Security Holders (b)
Description of Common Stock -- Repurchase by the Company of its Common Stock"
and so retires such shares, the selling shareholders are deemed to have received
a dividend in an amount equal to the selling price less the aggregate of the
stated capital and the additional paid-in capital attributable to the shares so
sold, except that if such retirement is made on or before March 31, 1999, no
such dividend is deemed to have been received but the entire profits realized by
the selling shareholders from such sales are treated as gains realized from the
ordinary sales of the shares and is subject to income tax or corporation tax, as
appropriate. In addition, when shares acquired by the Company (whether by way of
a tender offer or otherwise) for the purpose of retirement with retained
earnings are retired by the Company with retained earnings, the shareholders
existing at the time of such retirement are deemed to have received a dividend
in an amount equal to the amount of the stated capital attributable to the
retired shares and calculated in proportion to each shareholder's shares at the
time of such retirement, except that if such retirement is made on or before
March 31, 1999, no income tax is payable with respect to such portion deemed as
a dividend. If the Company purchases shares of its Common Stock for the purpose
of retirement with additional paid-in capital and so retires such shares, the
entire profits realized by the selling shareholders from such sales are treated
as gains realized from ordinary sales of the shares and is subject to income tax
or corporation tax, as appropriate. In this case, no taxable event is deemed to
accrue from such retirement to the shareholders existing at the time of
retirement.
 
United States Taxation of Common Stock or ADRs
 
       Dividends received by an U.S. holder of ADRs or Common Stock will be
includable in income as ordinary income for U.S. federal income tax purposes to
the extent paid out of current or accumulated earnings and profits of the
Company as determined for U.S. federal income tax purposes.
       Subject to limitations set out in the Code, a U.S. holder of ADRs or
Common Stock of the Company will be entitled to a credit for Japanese tax
withheld in accordance with the Convention from dividends paid by the Company.
For purposes of the foreign tax credit limitation, dividends will be foreign
source income, but will constitute "passive" or "financial services" income.
       Dividends paid by the Company to U.S. corporate holders of ADRs or Common
Stock will not be eligible for the dividends-received deduction.

Notes to Selected Financial Data:
 
1. Net income (loss) per share amounts were computed based on Statement of
   Financial Accounting Standards No. 128, "Earnings per Share" (FAS 128). All
   prior-period net income (loss) per share amounts have been restated to
   conform with FAS 128. FAS 128 requires presentation of basic and diluted net
   income per share on the face of the income statement. Under FAS 128, basic
   net income per share is computed based on the average number of shares of
   common stock outstanding during each period and diluted net income per share
   assumes the dilution that could occur if securities or other contracts to
   issue common stock were exercised or converted into common stock or resulted
   in the issuance of common stock. Refer to Note 2 and 3 of Notes to
   Consolidated Financial Statements.
 
2. During the fiscal year ended March 31, 1996, the Company changed its method
   of accounting for assessing the carrying values of intercompany foreign
   currency commitments to comply with the Emerging Issues Task Force Issue No.
   95-2. This did not have a material impact on results of operations for the
   years ended March 31, 1996, 1997, and 1998.
 
3. The consolidated results for the fiscal year ended March 31, 1995 reflect the
   write-off of goodwill of 265 billion yen in the Pictures segment and losses
   in the Pictures segment of approximately 50 billion yen arising from a
   combination of unusual items, such as abandoning a large number of projects
   in development and providing for settlement of outstanding lawsuits and
   contract claims.
 
4. Certain amounts at year-end for the prior years have been reclassified to
   conform to the 1998 presentation.
 
5. Cash dividends declared in U.S. dollars are based on the exchange rates at
   each respective payment date.

Item 9.   Management's Discussion and Analysis of Financial Condition and
Results of Operation
 
LIQUIDITY AND CAPITAL RESOURCES
 
Liquidity Management
 
       One of the most important policies of Sony's financial strategy is to
strengthen consolidated financial structure while keeping an appropriate level
of liquidity on hand. Aiming to strengthen financial structure, Sony has been
making efforts to redeem liabilities by utilizing cash and cash equivalents in
order to reduce the size of the balance sheet. In order to complement the
smaller liquidity resulting from making such efforts, Sony recently enhanced its
liquidity management by means of improving the committed credit facilities so
that it could eventually promote a credit-facility-oriented liquidity management
rather than a cash-based one.
       Sony generally maintains total liquidity equal to at least 80% of the
expected gross sales for the month in the year in which gross sales are expected
to be greatest plus 80% of debt redemption for the month in the year in which
total redemption are highest. In order to maintain a stable level of liquidity,
the Company entered into contracts with banks to establish committed credit
facilities for the first time in the fiscal year ended March 31, 1998. In
addition, Sony has maintained committed commercial paper (CP) backup lines of
its financial subsidiaries in the U.S. and Europe in order to maintain an
adequate level of liquidity in the regions.
       Sony selects banks on criteria in which banks rated "A" and "B" of
Moody's Bank Financial Strength ratings account for at least 70% of all
committed credit facilities and banks rated "C" for the remaining portion when
entering into backup and credit commitments. Sony conducts an annual review to
confirm that all banks continue to fulfill such rating conditions. In the fiscal
year ending March 31, 1999, Sony has set credit facilities amounting to
approximately 330 billion yen and apportioned the facilities among the Company
and its overseas subsidiaries in accordance with funding requirements of each
entity.
 
       Also, to further enhance Sony's liquidity, Sony is currently arranging a
U. S. 900 million dollar accounts receivable financing facility in the U.S. This
facility, whereby Sony securitizes its accounts receivables, enables Sony to
raise off-balance sheet funds.
 
Assets, Liability and Stockholders' Equity
 
       Total assets at March 31, 1998 were 6,403.0 billion yen, 12.7% more than
at the previous fiscal year-end. One reason for the increase was the yen's
depreciation at the end of the year compared with the previous fiscal year-end.
Among current assets, cash and time deposits rose mostly due to higher earnings,
and marketable securities increased as the Company raised short-term
investments. Notes and accounts receivable increased as sales grew with an
almost flat turnover ratio of trade receivables during the year. While growth in
sales resulted in increases in inventories, the inventory turnover ratio to cost
of sales (based on the average of inventories at March 31, 1997 and 1998)
improved by 0.22 months to 2.42 months resulting from efforts to shorten product
lead-times from manufacture to sale. The increase in investments and advances
was due to higher investment assets at Sony Life as insurance premium revenues
posted strong growth.
       Total current and long-term liabilities increased 8.7% to 4,461.7 billion
yen. Among current liabilities, short-term borrowings and debt declined sharply,
mainly due to the redemptions of medium-term notes (MTN) issued by a U.S.
subsidiary and maturing during the year. Repayment of MTN was refinanced through
the issuance of CP by the subsidiary. By the end of this fiscal year, most of
the outstanding CP was repaid using proceeds from the 1.5 billion U.S. dollar
Notes issued in March 1998.
 
                                       30
<PAGE>   31
 
Notes and accounts payable, trade and accounts payable, other and accrued
expenses increased due to the growth in Sony's businesses. Among long-term
liabilities, long-term debt increased only slightly despite the issuance of the
Notes because of the conversion of 146.5 billion yen of convertible bonds into
common stock during the year. As a result, total short- and long-term borrowings
and debt amounted to 1,303.8 billion yen, 8.7% less than the previous fiscal
year-end. The increase in accrued pension and severance costs resulted from a
reduction in the assumed discount rate used in developing projected benefit
obligations for Sony's Japanese plans, due to a decline in long-term interest
rates in Japan for the past few years, and from the minimum pension liability
recognized at March 31, 1998 (refer to Note 12 of Notes to Consolidated
Financial Statements). Future insurance policy benefits were higher because of
growth in insurance premium revenues at Sony Life.
       Stockholders' equity increased 24.4% to 1,815.6 billion yen, mostly
because of higher earnings and the conversion of convertible bonds. The ratio of
stockholders' equity to total assets increased by 2.7 percentage points, from
25.7% to 28.4%. Based on the number of shares outstanding at March 31, 1998,
stockholders' equity per share rose to 4,461.39 yen from 3,798.62 yen at the
previous fiscal year-end. In addition, the cumulative translation adjustment at
March 31, 1998 decreased in absolute amount to 140.7 billion yen from 181.2
billion yen at the previous fiscal year-end mainly due to the yen's
depreciation.
 
Cash Flows
 
       There was a net decrease in cash and cash equivalents at end of the year
of 5.2 billion yen, including the effect of exchange rate changes of 1.1 billion
yen, resulting in a balance of 423.3 billion yen at year-end.
       During the year, net cash provided by operating activities decreased to
612.4 billion yen from the previous fiscal year, mainly due to an increase in
inventories, decreases in accrued income and other taxes and other factors.
While the balance of inventories rose, the inventory turnover ratio to cost of
sales decreased, as is discussed in the assets, liabilities and stockholders'
equity section. The decrease in accrued income and other taxes was mainly due to
an increase in this account in the previous year, due to higher earnings at the
Company and its subsidiaries in Japan and smaller interim tax payments. Larger
interim tax payments in the fiscal year ended March 31, 1998 also contributed to
the decrease in accrued income and other taxes. Notes and accounts payable and
receivable increased; however, as was the case with inventories, both figures
decreased as a percentage of sales. Depreciation and amortization, including
amortization of goodwill and intangibles and deferred insurance acquisition
costs, rose 13.2% to 301.7 billion yen. This amount is broken down into tangible
assets for approximately 260 billion yen, goodwill and intangibles for
approximately 20 billion yen, and deferred insurance acquisition costs for
approximately 20 billion yen.
       During the year, net cash used in investing activities increased to 598.7
billion yen from the previous fiscal year, mainly due to higher payments for
purchases of fixed assets. Capital expenditures were up 26.8% to 378.1 billion
yen. Major components of the capital expenditures were approximately 70.0
billion yen in the semiconductor field, which was the largest amount, and
investments in such fields as displays and recording media. In the fiscal year
ending March 31, 1999, while Sony plans to maintain a high level of investment
in these business areas, total capital expenditures are expected to decrease.
Refer to the Major Agreements section for information on other investments and
loans.
       During the year, net cash used in financing activities decreased
significantly to 17.8 billion yen from the previous fiscal year. This was due to
a small net repayment of short-term borrowings, reflecting the substantial
demand for funds during the year mentioned above, compared to a significant net
repayment of short-term borrowings in the previous fiscal year. In addition,
proceeds from issuance of
 
                                       31
<PAGE>   32
 
debt, mainly of the Notes, increased from the previous fiscal year, while net
repayment of long-term debt also increased because of redemption, mainly of MTN
in the U.S.
 
Major Agreements
 
       This section details major agreements having an effect on liquidity or
earnings during the year and expected in the fiscal years ending March 31, 1999
and thereafter.
       In June 1997, the Company made an equity investment of approximately 5.0
billion yen in Japan Sky Broadcasting Co., Ltd. (JSkyB), a digital
communications satellite broadcaster. In May 1998, JSkyB and PerfecTV
Corporation completed their merger. As a result of this merger, the Company owns
11.375% of shares of the combined company, Japan Digital Broadcasting Services
Inc. Sony also invested a total of approximately 4.2 billion yen in broadcast
programming companies relating to the digital communications satellite
broadcasting business during the year. In the fiscal year ending March 31, 1999,
Sony plans to make additional investments of approximately 3.9 billion yen in
other broadcast programming companies. These communications satellite related
businesses are currently in start-up phases. Sony is committed to such new
business areas, and is required to make additional investments in accordance
with its share of equity.
       In October 1997, the Company and Toyoda Automatic Loom Works, Ltd.
jointly established S.T. Liquid Crystal Display Corp. for the purpose of
manufacturing next-generation LCD panels. During the year, Sony made an
investment in this firm of 4.0 billion yen. In the fiscal year ending March 31,
1999, Sony expects to make additional investments in this firm in the amount of
11.0 billion yen.
       In January 1998, Sony announced a plan to form a strategic alliance with
NextLevel Systems Inc. of the U.S. (now called General Instrument Corp.), to
jointly develop digital TV technologies, subject to definitive agreements. When
definitive agreements are reached, Sony plans to purchase 7.5 million shares of
General Instrument Corp. at a price of 25 U.S. dollars per share, resulting in a
total investment of approximately 187.5 million U.S. dollars.
       In May 1998, Loews Theatres Exhibition Group ("Loews Theatres"), a unit
of SPE, and Cineplex Odeon Corporation, a Canadian theatre chain, combined and
created Loews Cineplex Entertainment Corporation. In conjunction with the
combination, Sony received approximately 53.6 billion yen in cash from the
repayment of all of the intercompany debt of Loews Theatres, which was
refinanced with third party debt, and receipt of a dividend. Sony plans to use
these funds to reduce its U.S. debt and meet internal funding requirements. As a
result of the combination, SPE and certain of its subsidiaries owned 51.1%
(representing 49.9% of the voting shares) of Loews Cineplex Entertainment
Corporation. After giving effect to the public offering of shares of common
stock of Loews Cineplex Entertainment Corporation in August 1998, SPE and
certain of its subsidiaries currently own 38.5% of Loews Cineplex Entertainment
Corporation. The new company has been deconsolidated and Sony accounts for it on
the equity basis for the fiscal year ending March 31, 1999. The revenues and
operating income of Loews Theatres for the fiscal year ended March 31, 1998,
were approximately 56.3 billion yen and 2.5 billion yen, respectively. In
addition, Sony recorded a gain of approximately 4.8 billion yen on the
combination in the first quarter ended June 30, 1998.
       A building complex to house Sony's European headquarters, rental office
space, stores, residences, a movie and broadcasting museum with educational
facilities, and entertainment space is currently under construction in Berlin,
Germany. The structure is located in Potsdam Platz on a site that Sony purchased
from the City of Berlin. The developer of the building complex is a partnership
controlled by Sony, Tishman Speyer Properties, Inc. of the U.S., and Kajima
Corporation of Japan. Completion is scheduled for 2000. The budget for this
project is approximately 1.5 billion German marks. Of this amount, approximately
1.0 billion German marks will be procured by the partnership in the form of
project financing. In addition, Sony is constructing an entertainment complex
which includes stores and theatres
 
                                       32
<PAGE>   33
 
on a site in San Francisco, U.S.A. Completion is scheduled for 1999. The budget
for this project is approximately 85 million U.S. dollars. Sony also plans to
construct a similar entertainment complex in Tokyo, Japan, with completion
scheduled for 2000. Currently, the estimated budget for this project is
approximately 12.0 billion yen.
       In June 1998, Sony entered into an agreement with Fujitsu Limited to
jointly develop and manufacture next-generation semiconductor devices.
Manufacturing is scheduled to begin during the fiscal year ending March 31,
1999, and capital expenditures are estimated to total approximately 28.0 billion
yen.
       On August 12, 1998, SPE, together with certain partners, completed the
acquisition of Telemundo Group, Inc. (Telemundo), one of two Spanish-language
television broadcast companies currently operated in the United States. Through
a series of transactions, SPE now owns 50% of a newly formed company holding
Telemundo's network operations and 24.95% of an entity holding Telemundo's
station operations, including seven full-power UHF stations. SPE's initial
capital investment totaled approximately 15.1 billion yen.
 
RESULTS OF OPERATIONS
(The fiscal year ended March 31, 1998 compared to the fiscal year ended March
31, 1997)
 
Sales and Operating Revenue
 
       During the fiscal year ended March 31, 1998, Sony's consolidated sales
and operating revenue (herein referred to as "sales") increased in all business
segments. Along with the yen's depreciation, this resulted in a 1,092.4 billion
yen, or 19.3%, increase in sales compared with the previous fiscal year to
6,755.5 billion yen and the second consecutive fiscal year of record sales and
earnings.
 
Impact of Foreign Exchange Trends
 
       During the year, overseas (outside Japan) sales accounted for
approximately 73% of Sony's consolidated sales. During the year, the yen
depreciated approximately 8% against the U.S. dollar and 11% against the British
pound, but appreciated approximately 5% against the German mark, each in terms
of average rates, compared with the previous fiscal year. It is estimated that
sales and operating income would have been lower by approximately 291 billion
yen and 110 billion yen, respectively, than the reported figures if the average
value of the yen had remained the same as in the previous fiscal year. Note that
these estimates are obtained by simply applying the yen's average exchange rate
in the prior fiscal year to foreign currency denominated sales, cost of sales,
and selling, general and administrative expenses of the year under review.
Therefore, the estimate does not take into account the effect of foreign
exchange fluctuations on prices of products and production and sales costs in
each region of the world. Constant currency growth rates discussed in the
Results by Business Segment are also calculated as above.
       To minimize the adverse effects of foreign exchange fluctuations on its
financial results and to reduce inventory and cost, Sony promotes the
localization of material and parts procurement, design, and manufacturing
operations outside Japan. During the year, Sony expanded manufacturing
operations mainly in North America and Eastern Europe. Overseas activities
represented approximately 50% of total manufacturing output in Sony's
Electronics business. Sony employs foreign exchange forward contracts
and foreign currency option contracts to hedge against foreign exchange risks
that arise from the export and import transactions of the Company and its
consolidated subsidiaries. In addition, interest rate and currency swap
agreements are used in connection with certain foreign currency denominated
borrowings and debt.
 
                                       33
<PAGE>   34
 
Impact of the Asian Currency Turmoil and Weak Local Markets
 
       During the year, Asia accounted for approximately 13% of sales in Sony's
Electronics business, while comprising approximately 25% of manufacturing. About
63% of this manufacturing output in Asia was exported for sale outside the
region.
       Currency and economic turmoil occurred in Asia during the second half of
1997. The overall impact of this situation was positive for Sony's earnings
during the year, mainly due to a decline in costs in Asia, a major manufacturing
base for Sony. However the decline in Asian currencies is expected to lead to
aggressive price-cutting from competing companies with Asian production bases,
making it difficult for Sony to continue to benefit from the cost reductions
brought about by weakened Asian currencies.
       Sony's Electronics sales in Asia including China, Australia and New
Zealand in the fiscal year ended March 31, 1998 increased by 2% from the prior
year. During the year, sales results in Asian countries were mixed. Sony's sales
in Thailand were negatively impacted by the currency and economic turmoil.
Sony's sales in Hong Kong declined due to poor economic conditions. However,
Sony's sales in Indonesia and Malaysia increased, compared with the previous
year.
 
Impact of Sluggish Market Conditions in Brazil
 
       Sales in Brazil experienced a significant decline mainly due to lower
sales of color TVs and audio equipment because of a worsening economic
environment and bankruptcies of dealers.
 
Cost of Sales and Selling, General and Administrative Expenses
 
       During the year, cost of sales rose by 688.9 billion yen, or 17.5%, to
4,619.0 billion yen, mainly due to higher sales. However, the ratio of cost of
sales to consolidated sales improved 0.8 percentage point, to 71.5%. This
improvement was attributable to the sales growth, continuous cost reduction
efforts, the yen's depreciation against the U.S. dollar and a reduction in
manufacturing costs due to falling Asian currencies in the second half of the
fiscal year; this ratio was, however, adversely affected by reductions in sales
prices due to intense competition worldwide. Research and development expenses
charged to cost of sales increased by 35.5 billion yen, or 12.6%, to 318.0
billion yen, mainly due to increases in the semiconductor business, information
and communication business, and Game business, but declined by 0.3 percentage
point as a percentage of sales, to 4.9%. Research and development expenses for
the fiscal year ending March 31, 1999 are expected to exceed those of the year
under review, mainly due to higher expenses in business areas such as
broadcast-use equipment and digital network related equipment as well as the
semiconductor business.
       Selling, general and administrative expenses rose by 191.7 billion yen,
or 16.6%, to 1,345.6 billion yen, mainly due to sales growth as well as
increases in personnel expenses and advertising costs in the Game business, but
improved 0.4 percentage point as a percentage of sales, to 20.8%.
       Figures in the above two paragraphs do not include the Insurance segment
revenue and expenses.
 
                                       34
<PAGE>   35
 
Operating Income
 
       Operating income during the year grew by 149.9 billion yen, or 40.5%, to
520.2 billion yen. Despite an increased operating loss in the Other segment,
higher operating income in the Electronics, Music, Pictures, and Insurance
segments, and particularly strong results in the Game segment, contributed to
overall growth. Sales and operating income in the Game segment reached
approximately 10% and 22%, respectively, of Sony's consolidated sales and
operating income before elimination of intersegment transactions. As a
percentage of sales, operating income improved by 1.2 percentage points, to
7.7%.
 
Other Income and Expenses
 
       Other income decreased by 8.7 billion yen, or 9.4%, to 84.0 billion yen,
while other expenses remained at 150.4 billion yen about the same as that in the
previous fiscal year. The decline in other income is primarily due to a decrease
in the foreign exchange gain, net, compared with the previous fiscal year.
Foreign exchange gains and losses mainly arise from the difference between the
value of foreign currency denominated exports and imports when converted into
various currencies using prevailing exchange rates and the value at settlement
of these exports and imports. The rates used for settlement are primarily based
on foreign exchange forward contracts and foreign currency option contracts that
Sony employs to hedge risks from exchange rate fluctuations. Among other income
and expenses, interest and dividends increased, mainly because of an increase in
cash and time deposits and higher investment returns at overseas subsidiaries.
Interest expense decreased, mainly due to lower outstanding debt at overseas
subsidiaries. As a result, the balance of interest and dividend income less
interest expense improved by 9.9 billion yen to net interest expense of 41.5
billion yen.
 
Income Before Income Taxes
 
       Income before income taxes during the year rose by 141.3 billion yen, or
45.2%, to 453.7 billion yen.
 
Income Taxes
 
       Income taxes as a percentage of income before income taxes (the effective
tax rate) declined 5.0 percentage points, to 47.4%. The decline in the effective
tax rate is mainly attributable to a reduction in the loss incurred by
subsidiaries for which there was no tax benefit. Due to the reduction of the
Japanese statutory income tax rate, effective April 1, 1998, the new statutory
tax rate has been used in calculating the future expected tax effects of
temporary differences. The effect of the enacted change in tax rate, which
resulted in a reduction of income tax expenses, was insignificant (refer to Note
13 of Notes to Consolidated Financial Statements).
       The valuation allowance mainly relates to deferred tax assets of
consolidated subsidiaries in the U.S. with operating loss carryforwards for tax
purposes. Sony believes there is little likelihood that such deferred tax assets
will be realized.
 
Net Income
 
       Net income increased by 82.6 billion yen, or 59.2%, to 222.1 billion yen.
Basic net income per share was 557.7 yen and diluted net income per share was
483.4 yen. Net income represented 3.3% of sales, up 0.8 percentage point, and
the return on average stockholders' equity increased 3.0 percentage points, to
13.6%.

Results by Business Segment
 
       The following discussion is based on segment information (refer to Note
18 of Notes to Consolidated Financial Statements).
 
Electronics
 
       During the year, despite weak markets in Brazil and Asia, including
China, many successful products and the yen's depreciation helped to increase
Electronics sales by 558.5 billion yen, or 13.5% (up approximately 10% on a
constant currency basis), to 4,690.1 billion yen. Operating income increased by
75.2 billion yen, or 31.4%, to 314.5 billion yen, and as a percentage of sales
improved by 0.9 percentage point to 6.7%. Operating income was aided by the
yen's depreciation against the U.S. dollar and the decrease in manufacturing
costs due to the decline in the value of Asian currencies as well as sales
growth and the benefits of cost cutting. However, late in the fiscal year, the
business environment in Electronics became more difficult due to deterioration
in the semiconductor business and slowing sales in Southeast Asia. Sales in
Japan, where Sony had attained steady growth despite sluggish market conditions,
also slowed toward the end of the fiscal year.
       Breaking down Electronics sales to customers by product category, "Audio"
products sales grew by 97.8 billion yen, or 9.5%, to 1,127.8 billion yen due to
sales expansion of MiniDisc systems. However lower growth in sales of car audio
products and a decline in sales of Walkman headphone stereos partially offset
growth in this category. Sales also expanded by 54.3 billion yen, or 6.6%, to
870.9 billion yen in the "Video" category, as demand grew for home-use digital
camcorders and the Digital Mavica still camera. Although the highly successful
Wega series of color TVs in Japan, which incorporate flat-surface cathode ray
tubes, contributed to sales in "Televisions", the category overall increased by
only 5.0 billion yen, or 0.7%, to 709.0 billion yen, due to sluggishness in
Brazil and Asia, including China. Sales in the "Information and communications"
category increased by 130.3 billion yen, or 17.0%, to 894.8 billion yen, boosted
by the popularity of new VAIO notebook PCs in Japan, and expansion of digital
cellular phone sales in Japan, the U.S., and Europe. However, a slowing of
computer display sales caused by weakness in PC markets partially offset growth
in the category. In the "Electronic components and other" category, sales grew
by 159.7 billion yen, or 26.0%, to 774.9 billion yen primarily due to higher
sales in electronic components such as optical pickups, more than offsetting
declining demand for memory chips.
 
Game
 
       The Game business posted extremely strong results due to the popularity
of PlayStation game consoles and software worldwide. Sales increased by 303.3
billion yen, or 72.3% (up approximately 64% on a constant currency basis), to
722.6 billion yen. Operating income more than doubled from the previous fiscal
year, reaching 116.9 billion yen and rose by 2.6 percentage points, to 16.2% of
sales. In addition to strong growth in console sales outside Japan, sales of
software, which has a high profit margin, rose as a percentage of sales in the
Game business along with the growing number of consoles in use. During the year,
worldwide production shipments of PlayStation game consoles increased to 19.37
million units compared with 9.2 million units in the previous fiscal year. As of
March 31, 1998, cumulative production shipments to markets worldwide have
reached 32.82 million consoles and 236 million software units.
 
Music
 
       Sony's Music business continued to post strong results as revenue
increased by 102.6 billion yen, or 17.3% (up approximately 11% on a constant
currency basis), to 694.7 billion yen. Operating income
 
                                       36
<PAGE>   37
 
increased by 8.9 billion yen, or 19.6%, to 54.1 billion yen. As a percentage of
sales, operating income improved by 0.2 percentage point, to 7.8%. The Music
group performed strongly throughout most territories around the world. Global
bestsellers, combined with local artist successes worldwide, contributed to the
year's results, more than offsetting lower results from direct marketing
operations in the U.S.
 
Pictures
 
       Sony's Pictures business recorded strong results. Revenue increased by
204.6 billion yen, or 46.7% (up approximately 35% on a constant currency basis),
to 643.2 billion yen. Sales increased significantly over the prior year,
benefiting from record motion picture box office revenue and strong sell-
through video sales as well as the inclusion of 13 months of activity from March
1, 1997 to March 31, 1998 due to a change in the Pictures group fiscal year. In
television operations, the group benefited from continued strong performance
from its game shows and daytime programs as well as network and syndication
revenue. Operating income was up by 6.6 billion yen, or 22.9% to 35.5 billion
yen, but declined 1.1 percentage points, to 5.5% of sales. This was mainly due
to the start-up losses on new international television ventures and losses due
to the underutilization of its special effects studio.
 
Insurance
 
       The expansion of Sony's life insurance business in Japan led to growth in
insurance revenue during the year. Insurance revenue increased by 63.1 billion
yen, or 27.7%, to 291.1 billion yen. Operating income grew by 1.2 billion yen,
or 6.4%, to 20.3 billion yen but declined 1.4 percentage points, to 7.0% of
sales. The lower operating margin was primarily due to an increase in
amortization of deferred insurance acquisition costs and higher expenses such as
benefit payments at Sony Life. Expenses related to the acquisition of new
policies and other expenses that fluctuate in relation to such acquisitions are
accounted for as deferred insurance acquisition costs and amortized over the
premium-paying period of the insurance policies (refer to Notes 2 and 10 of
Notes to Consolidated Financial Statements). The amortization of deferred
insurance acquisition costs increased by 6.0 billion yen, or 37.7%, to 21.8
billion yen.
 
       In July 1997, Sony Life received a capital infusion from the Company,
increasing its capital by 28.0 billion yen to 50.0 billion yen. This action was
taken to ensure the ability to further preserve and enhance Sony Life's
soundness and to ensure the ability to adapt to changes in the operating
environment caused by Japan's Big Bang of financial deregulation. Furthermore,
taking advantage of growing opportunities created by deregulation, Sony is
evaluating the benefits of entering property and casualty insurance business in
Japan. Focusing on automobile insurance, Sony is aiming to enter this business
in the second half of the fiscal year ending March 31, 2000.
 
Other
 
       The Other segment consists of various operating activities including
customer financing, leasing, broadcasting, networking, and other businesses.
Sales in the Other segment grew by 7.9 billion yen, or 3.3%, to 248.2 billion
yen and the operating loss increased to 10.3 billion yen from the prior year's
operating loss of 1.4 billion yen. This increase in the operating loss was due
to higher costs incurred in the start-up of new businesses including location
based entertainment businesses, satellite distribution services, and
internet-related businesses.

Outlook
 
       The following outlook is based on current business conditions and
management's outlook and on the assumption that the average yen-dollar exchange
rate for the remainder of the fiscal year ending March 31, 1999, will be around
135 yen. It is anticipated that any favorable impact on operating income of a
depreciation of the yen from this assumption against various currencies in terms
of average rates would be very limited, mainly due to severe price competition
in the electronics business. While sales are expected to increase, Sony
estimates that earnings will be lower and recognizes that recent instability in
global financial markets, especially currency and stock markets, caused by Asian
currency turmoil since last year followed by the recent currency devaluation in
Russia, has been increasing uncertainty regarding Sony's sales and earnings
outlook. As for cash flows during the fiscal year ending March 31, 1999, net
cash provided by operating activities is anticipated to decrease, due to lower
earnings and larger increase of accounts receivable than that of accounts
payable resulting from reducing inventory as well as growing sales, while
depreciation and amortization is projected to be higher in the fiscal year
ending March 31, 1999. Cash used in investing activities is expected to decrease
from the previous year mainly through maintaining lower level of capital
expenditures and is to be covered by the net cash provided by operating
activities.
       In the Electronics segment, while sales in areas such as Brazil, Russia,
and Asia are forecast to be sluggish due to no foreseeable improvement in the
market conditions in these areas during the period, sales are expected to
increase overall, due to sales growth in Japan and Western Europe and the yen's
depreciation. However, intense price competition in broadcast- and
professional-use equipment, computer displays and cellular phones, as well as a
lack of improvement in semiconductor markets, will make it difficult in the
fiscal year ending March 31, 1999, to maintain the level of earnings generated
in the fiscal year ended March 31, 1998.
       In the Game segment, despite sales growth in the U.S. and Europe as well
as the yen's depreciation, lower sales in Japan and an increase in next
generation PlayStation-related R&D expenses are forecast to cause a slight
profit decline.
       In the Music segment, despite continuing sluggishness in worldwide CD
sales, growth outside Japan is expected to continue. While efforts in Japan are
underway to develop new and established artists, the operating environment in
that market remains challenging.
       In the Pictures segment, while earnings from "Godzilla" are less than
expected, contributions from carryover releases, other current year releases,
and the television business lead to a projection of relatively flat profit for
the fiscal year.
       The insurance segment is expected to post another year of solid growth
despite challenges posed by rising competition due to deregulation of financial
services in Japan.
       In the Other segment, new business areas such as satellite broadcasting
remain in start-up stages and cannot be expected to contribute to profit.
       In this business environment, Sony is continuing to work toward improving
its business results by efforts such as strengthening the competitiveness of its
products, carefully selecting investments, imposing more rigorous inventory
control, and raising the efficiency and effectiveness of operations through
enhancement of its supply chain management systems mainly in the Electronics
business.

(The fiscal year ended March 31, 1997 compared to the fiscal year ended March
31, 1996)
 
Sales and Operating Revenue
 
       During the fiscal year ended March 31, 1997, sales growth across all
businesses except the Other segment as well as the yen's depreciation led to a
1,070.6 billion yen, or 23.3%, increase in sales to 5,663.1 billion yen.
 
Impact of Foreign Exchange Trends
 
       During the year, overseas (outside Japan) sales accounted for
approximately 72% of Sony's consolidated sales. During the year, the yen
depreciated approximately 15% against the U.S. dollar, 7% against the German
mark, and 16% against the British pound, each in terms of average rates,
compared with the previous fiscal year. It is estimated that sales and operating
income would have been lower by approximately 520 billion yen and 150 billion
yen, respectively, than the reported figures if the average value of the yen had
remained the same as in the previous fiscal year. Note that these estimates are
obtained by simply applying the yen's average exchange rate in the prior fiscal
year to foreign currency denominated sales, cost of sales, and selling, general
and administrative expenses of the year under review. Therefore, the estimate
does not take into account the effect of foreign exchange fluctuations on prices
of products and production and sales costs in each region of the world. Constant
currency growth rates discussed in the Results by Business Segment are also
calculated as above.
 
Cost of Sales and Selling, General and Administrative Expenses
 
       During the year, cost of sales rose by 713.3 billion yen, or 22.2%, to
3,930.1 billion yen, mainly due to higher sales. However, the ratio of cost of
sales to consolidated sales improved 1.1 percentage points, to 72.3%. This
improvement was mostly attributable to a significant depreciation of the yen. In
some cases, this depreciation enabled Sony to lower effective sales prices to
preserve and increase its competitive edge, leading to higher sales and market
shares. Nevertheless, continuous efforts to cut costs resulted in a decline in
the cost of sales ratio. Research and development expenses charged to cost of
sales increased by 25.2 billion yen, or 9.8%, to 282.6 billion yen, mainly due
to increases in the information and communication business and semiconductor
business, but declined by 0.7 percentage point as a percentage of sales, to
5.2%.
       Selling, general and administrative expenses increased 216.0 billion yen,
or 23.0%, to 1,153.9 billion yen, mainly due to sales growth as well as
increases in personnel expenses and advertising costs in the Electronics
business and Game business, but improved 0.2 percentage point as a percentage of
sales, to 21.2%.
       Figures in the above two paragraphs do not include the Insurance segment
revenue and expenses.
 
Operating Income
 
       Operating income during the year increased by 135.0 billion yen, or
57.4%, to 370.3 billion yen. The Game segment began making a substantial
contribution to operating income, and operating income was higher in the
Electronics, Music, Pictures, and Insurance segments as well. Sales and
operating income in the Game segment reached approximately 7% and 15%,
respectively, of Sony's consolidated sales and operating income before
elimination of intersegment transactions. As a percentage of sales, operating
income improved by 1.4 percentage points, to 6.5%.
 
                                       39
<PAGE>   40
 
Other Income and Expenses
 
       Other income increased by 26.9 billion yen, or 40.9%, to 92.6 billion
yen, while other expenses decreased by 12.4 billion yen, or 7.6%, to 150.5
billion yen. These changes are primarily attributable to the foreign exchange
gain, net, posted during the year, following a substantial foreign exchange
loss, net, in the prior fiscal year. During the year, the exchange rates of the
yen at settlement of foreign currency denominated sales were about the same as
prevailing exchange rates at the date of the sales. However, yen exchange rates
for settlement of imports were higher than prevailing rates at the date of the
purchase, resulting in a foreign exchange gain. Among other income and expenses,
the balance of interest and dividend income less interest expense resulted in
net interest payments of 51.5 billion yen. This is 2.4 billion yen more than in
the previous year, mainly because of the yen's depreciation.
 
Income Before Income Taxes
 
       Income before income taxes during the year rose by 174.3 billion yen, or
126.1%, to 312.4 billion yen.
 
Income Taxes
 
       Income taxes as a percentage of income before income taxes (the effective
tax rate) declined 3.5 percentage points, to 52.4%. Both consolidated income
before income taxes and loss at subsidiaries, that have no tax benefit because
they were in a loss carryforward position, increased this year. Since increase
in consolidated income before income taxes was larger than increase in loss at
subsidiaries, the effective tax rate declined.
 
Net Income
 
       Net income increased by 85.2 billion yen, or 157.1%, to 139.5 billion
yen. Basic net income per share was 367.7 yen and diluted net income per share
was 309.2 yen. Net income represented 2.5% of sales, up 1.3 percentage points,
and the return on average stockholders' equity increased 5.6 percentage points,
to 10.6%.
 
Results by Business Segment
 
       The following discussion is based on segment information (refer to Note
18 of Notes to Consolidated Financial Statements).
 
Electronics
 
       During the year, growth in all product categories and the yen's
depreciation lifted Electronics sales by 666.2 billion yen, or 19.2% (up
approximately 8% on a constant currency basis), to 4,131.6 billion yen.
Operating income increased by 46.0 billion yen, or 23.8%, to 239.3 billion yen,
and as a percentage of sales improved by 0.2 percentage point to 5.8%. A higher
gross profit due to sales growth, the benefits of cost cutting, and the yen's
depreciation were major contributors.
       Breaking down Electronics sales to customers by product category, "Audio"
products sales increased by 129.6 billion yen, or 14.4%, to 1,030.0 billion yen
because of higher sales of MiniDisc systems and car audio products. Sales rose
by 85.5 billion yen, or 11.7%, to 816.6 billion yen in the "Video" category, as
demand grew for home-use camcorders. In "Televisions", sales increased in Japan,
the U.S. and Europe, but were lower in China and Russia. The result was an
increase of 150.1 billion yen, or 27.1%, to 704.1 billion yen. Although sales of
CD-ROM drives decreased, sales of computer displays
 
                                       40
<PAGE>   41
 
rose worldwide and sales of digital cellular phones were up in Japan, the U.S.
and Europe. This caused sales in the "Information and communications" category
to increase by 223.8 billion yen, or 41.4%, to 764.5 billion yen. In the
"Electronic components and other" category, sales were up by 58.2 billion yen,
or 10.4%, to 615.2 billion yen as growth in sales of lithium-ion batteries
offset weakness in memory chips and optical pickups.
 
Game
 
       Sales in the Game business more than doubled (up approximately 94% on a
constant currency basis) to 419.3 billion yen. Operating income was 57.0 billion
yen, compared with an operating loss of 8.9 billion yen in the previous fiscal
year. Sales growth of game consoles was strong in Japan as well as the U.S. and
Europe. There was also a substantial increase in software, which has a high
profit margin, as a percentage of sales in the Game business. During the year,
worldwide production shipments of PlayStation game consoles were 9.2 million
units.
 
Music
 
       Strong overseas results raised Music business revenue by 74.2 billion
yen, or 14.3% (up approximately 4% on a constant currency basis), to 592.1
billion yen. Operating income grew by 5.1 billion yen, or 12.7%, to 45.2 billion
yen. As a percentage of sales, operating income decreased by 0.1 percentage
point, to 7.6%. This decrease mainly reflects restructuring steps taken at SMEJ.
SMEJ revised its policy for releasing new titles and reduced the number of new
releases, causing earnings to fall.
 
Pictures
 
       Despite disappointing box office results from certain releases, results
in the Pictures business were supported by growth in sell-through video sales,
television operations, and licensing agreements involving SPE's filmed
entertainment library. As a result, revenue rose by 121.0 billion yen, or 38.1%
(up approximately 20% on a constant currency basis), to 438.6 billion yen.
Operating income increased by 5.1 billion yen, or 21.2%, to 28.9 billion yen,
but decreased by 0.9 percentage point to 6.6% as a percentage of sales.
 
Insurance
 
       The expansion of Sony's life insurance business in Japan caused insurance
revenue to increase by 21.0 billion yen, or 10.2%, to 227.9 billion yen.
Operating income surged 12.0 billion yen, or 168.4%, to 19.1 billion yen and
rose 5.0 percentage points, to 8.4% of sales. The improvement in the operating
margin mainly reflects a decrease in the addition to liability for future
insurance policy benefits in relation to the prior fiscal year when there was a
large increase in single premium life insurance policies, which require a
greater ratio of liability for future insurance policy benefits.
 
Other
 
       Sales in the Other segment decreased by 33.6 billion yen, or 12.3%, to
240.4 billion yen and the operating loss declined to 1.4 billion yen from the
prior year's operating loss of 6.1 billion yen. The prior year's loss was mostly
caused by the termination of a 16-bit game software business at an U.S.
subsidiary.

The Year 2000 Issue
 
       Until recently, computer programs were generally written using two digits
rather than four to define the applicable year. Accordingly, such programs may
be unable to distinguish properly between the year 1900 and the year 2000.
       Sony has initiated a comprehensive corporate-wide project to implement a
transition into the year 2000 for all internal information systems and Sony
products. In October 1997, Sony completed an identification and assessment
project in respect of the potential impact of the Year 2000 issue on Sony's
products, by May 1998, established a structure to enable it to address this
issue around the world. With plans continuing on schedule, Sony expects to
complete remediation of the Year 2000 issue for major internal information
systems by December 1998, although no assurance can be given of timely
completion of this project. Sony is also taking steps intended to ensure that
customers around the world will be able to depend on Sony products in and after
the year 2000. In the broadcast- and professional-use product field, Sony
continues to work with its customers to address the Year 2000 issue, and expects
completion by the end of March 1999, although no assurance can be given of
timely completion of this project.
       The external cost to modify all internal information systems for
compliance with the Year 2000 issue is estimated to be approximately 9.2 billion
yen, of which approximately 2.1 billion yen was expensed as incurred by the end
of the fiscal year ended March 31, 1998. Additionally, while extremely difficult
to estimate precisely, the cost to replace certain internal information systems,
including hardware equipment, relating to the Year 2000 issue is estimated to be
approximately 13 billion yen. This cost includes other elements such as
enhancement of functionality of current systems. The external cost associated
with the Year 2000 issue for all Sony products is currently expected to be
minimal. Sony expects total external cost of Year 2000 compliance would not have
a material adverse effect on consolidated operations and financial results.
       For major software and hardware which comprise Sony's information systems
and major non-IT systems such as production equipment which contain
microcontrollers, Sony has taken steps to assess the level of risk by acquiring
information from external vendors and, where necessary, asking for written
reports to confirm the status of compliance measures for the Year 2000 issue.
Sony is also addressing the information systems of external vendors by obtaining
confirmations from external service suppliers and tests are conducted where
necessary. However, given the reliance on the third party information as it
relates to their compliance programs and the difficulty of determining potential
errors on the part of external service suppliers, no assurance can be given that
Sony's information systems or operations will not be affected by mistakes, if
any, of third parties or third party failures to complete the Year 2000 project
on a timely basis.
       The cost of Sony's Year 2000 project and the date on which Sony believes
it will complete the necessary modifications are based on Sony's estimates,
which were derived utilizing numerous assumptions of future events, including
the continued availability of resources, third party modification plans and
other factors. Sony presently believes that the Year 2000 issue will not pose
significant operational problems for its internal information systems and
products. However, if the anticipated modifications and conversions are not
completed on a timely basis, or if the systems of other companies on which
Sony's systems and operations rely are not converted on a timely basis, the Year
2000 issue could have an adverse effect on Sony's operations.
       Sony recognizes the importance of readiness for potential worst case
scenarios. As a result, Sony is working to identify scenarios requiring
contingency plans; however, to date no such plans have been established.

Euro
 
       The January 1, 1999 scheduled adoption of the Euro will create a
single-currency market in much of Europe. For a transition period from January
1, 1999 to January 1, 2002, the existing local currencies are anticipated to
remain legal tender as denominations of the Euro.
       In March 1998, Sony completed a project to identify and assess the
potential impact of the adoption of the Euro on its operations. Sony is making
preparations to handle Euro invoices for transactions with third parties from
January 1999. Sony intends to take action in marketing areas as necessary to
deal with these ongoing changes. Regarding transactions within the Sony Group,
preparations are under way to enable all such transactions to be switched to the
Euro from the local currencies of EMU countries in April 1999, although no
assurance can be given that such transactions will be switched to the Euro by
such time. This will eliminate the need for foreign exchange commissions and
hedging expenses. Sony estimates that this will result in an annual cost saving
in Europe of approximately 20 million German marks.
       Due to the preparation for adoption of the Euro, Sony will need to
conduct a certain number of revisions to its information systems. Such revisions
have started and are proceeding on schedule to the anticipated completion date
of December 1998 for systems related to transactions with the third parties and
March 1999 for systems related to transactions within the Sony Group,
respectively. Sony expects the cost of such revisions would not have a material
adverse effect on consolidated operations and financial results. However, no
assurance can be given that such revisions will be completed on a timely basis.
       No policy change is expected on foreign exchange hedging for trades
between Europe and other regions as well as funding in Europe even after the
adoption of the Euro.
 
Item 9A.   Quantitative and Qualitative Disclosures About Market Risk
 
       The financial instruments including financial assets and liabilities that
Sony holds in the normal course of business are continuously exposed to
fluctuations in markets, such as currency exchange rates, interest rates, and
market prices of investments. In applying a consistent risk management strategy
in order to remove adverse effects caused by market fluctuations in the cash
flow value of these financial instruments, Sony hedges the market risk of these
financial assets and liabilities by using derivative financial instruments which
include foreign exchange forward contracts, foreign currency option contracts,
interest rate swap agreements, and interest rate and currency swap agreements.
Sony utilizes foreign exchange forward contracts and foreign currency option
contracts primarily to fix the value of cash flow resulting from accounts
receivable and payable and future transactions denominated in foreign currencies
in relation to the core currencies (Japanese yen, U.S. dollars, and German
marks) of Sony's major operating units. Interest rate swap agreements and
interest rate and currency swap agreements are used to diversify funding methods
and lower funding costs. Sony's basic policy is to use fixed interest rates when
procuring funds for investments having a long-term recovery period and variable
interest rates for funding requirements of a short-term nature, such as working
capital. The above swaps are utilized to enable Sony to choose between fixed and
variable interest rates depending on how the funds are to be used, as well as to
hedge foreign exchange risks that result when assets denominated in one currency
are funded by liabilities denominated in a different currency. Sony uses these
derivative financial instruments solely for risk hedging purposes as described
above, and no derivative transactions are held or used for trading purposes. In
addition, bond option contracts are used as an integral part of short-term
investing activities in order to fix the yields from bonds held by Sony Life to
certain ranges. Note that among the market risks described above, no specific
hedging activities are taken against the price
 
                                       43
<PAGE>   44
 
fluctuations of equity securities held by Sony as marketable securities (refer
to Notes 2 and 11 of Notes to Consolidated Financial Statements).
       Sony measures the effect of market fluctuations on the value of financial
instruments and derivatives by using Value-at-Risk (herein referred to as "VaR")
analysis. In order to comply with Item 9A disclosure requirements, Sony uses VaR
which measures a potential maximum amount of loss in fair value resulting from
adverse market fluctuations, for a selected period of time and at a selected
level of confidence. Sony uses the variance/co-variance model in calculation of
VaR. The calculation includes financial instruments such as cash and cash
equivalents, time deposits, marketable securities, non-lease short- and
long-term borrowings and debt, investments and advances and derivatives, held by
the Company and consolidated subsidiaries. Sony calculates VaR for one day from
the portfolio of financial instruments and derivatives as of March 31, 1998, at
a confidence level of 95%.
       Based on this assumption, Sony's consolidated VaR at March 31, 1998 is
calculated to be 6.9 billion yen, which indicates the potential maximum loss in
fair value resulting from market fluctuations in one day at a 95% confidence
level. By item, the VaR of currency exchange rate risk is calculated to be 7.2
billion yen which mainly consists of risks arising from the volatility of the
exchange rates between yen and U.S. dollars in which relatively large amount of
financial assets and liabilities and derivative transactions is maintained. VaR
of interest rate risk and stock price risk are calculated to be 3.4 billion yen
and 3.3 billion yen, respectively. The net VaR for Sony's entire portfolio is
smaller than the simple aggregate of VaR for each component of market risk. This
is due to the fact that market risk factors such as currency exchange rates,
interest rates, and stock prices are not completely independent, thus have the
effect of offsetting a portion of overall profits and losses.
       The calculated VaR does not include the effect of accounts receivable and
payable and anticipated transactions denominated in foreign currencies as of
March 31, 1998, that are the object of Sony's derivative hedging. Therefore, the
above amount of VaR does not reflect the full effect of the hedging activities
related to all of the underlying exposures and Sony expects that the actual risk
would be less than the disclosed VaR if those accounts receivable and payable
and anticipated transactions are taken into account in the calculation. The
disclosed VaR amount simply represents the calculated potential maximum loss on
the following day and by no means indicates an estimate of future loss.

COMPLIANCE WITH STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS
 
       Effective for the fiscal year ended March 31, 1998, Sony adopted
Statement of Financial Accounting Standards No. 131 (FAS 131). This resulted in
the reporting of business results based on new operating segments (refer to Note
18 of Notes to Consolidated Financial Statements). Segment information as well
as certain items in the consolidated statements of income in prior fiscal years
have been reclassified to conform to the presentation for the fiscal year ended
March 31, 1998.
       Sony also adopted FAS 128 during the fiscal year ended March 31, 1998.
FAS 128 requires presentation of basic and diluted net income per share on the
face of the statements of income (refer to Notes 2 and 3 of Notes to
Consolidated Financial Statements). Net income per share amounts in prior fiscal
years have been restated to conform with FAS 128.
       In June 1997, the FASB issued FAS 130, "Reporting Comprehensive Income".
This standard requires additional disclosures in the financial statements for
periods beginning after December 15, 1997, and will have no effect on Sony's
financial position or results of operations.
       In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use". This SOP, which is effective
for financial statements for fiscal years beginning after December 15, 1998,
provides guidance on accounting for the costs of computer software developed or
obtained solely to meet the company's internal needs. Sony adopted the SOP in
the first quarter of the year ending March 31, 1999. At this stage, it is not
possible to estimate the impact of adoption on Sony's financial statements for
the full fiscal year ending March 31,1999, although the effect of this change on
the first quarter results was not material.
       In June 1998, the FASB issued FAS 133, "Accounting for Derivative
Instruments and Hedging Activities". This standard, which is effective for
fiscal years beginning after June 15, 1999, requires all derivatives to be
recognized in the statement of financial position as either assets or
liabilities and measured at fair value. To implement this standard, all hedging
relationship must be reassessed. At this stage, it is not possible to estimate
the impact of adoption on Sony's financial position or results of operations.

Item 10.   Directors and Statutory Auditors of Registrant
 
       On June 27, 1997, the Company altered the composition of its Board of
Directors and at the same time introduced a new system of executive officers.
While the Company has been selecting appropriate and qualified persons mainly
from the management of Sony as candidates for directorship, the Company intends
to increase the number of outside Directors in order to reinforce the Board's
supervisory function on the conduct of business. The number of Directors was
reduced so that more active discussion may be conducted among Directors. Under
the new system of executive officers, the executive officers appointed by the
Board of Directors execute their respective assigned duties upon the delegation
of power and authority by the Representative Directors, who have unlimited
statutory authority and power to represent and act on behalf of the Company in
all respects, and assist the relevant Representative Directors in their
respective areas of responsibility. This new system was introduced with a view
to strengthening the executive function of officers headed by the Representative
Directors who are in charge of business operations in line with the basic
policies set by the Board of Directors and under the supervision of the Board of
Directors.
 
       On May 7, 1998, President Nobuyuki Idei became Co-Chief Executive Officer
(Co-CEO). In his role as Co-CEO, President Idei shares with Chairman and CEO
Norio Ohga the responsibility for overseeing management operations of the
Company.
 
       Set forth below are the names of the Company's Directors and Statutory
Auditors as of July 1, 1998.

                       Report of Independent Accountants
 
To the Stockholders and Board of Directors of
Sony Corporation (Sony Kabushiki Kaisha)
 
In our opinion, the consolidated financial statements listed in the accompanying
index present fairly, in all material respects, the financial position of Sony
Corporation and its consolidated subsidiaries at March 31, 1997 and 1998, and
the results of their operations and their cash flows for each of the three years
in the period ended March 31, 1998, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  Nature of operations:
 
The company is engaged in the development, design, manufacture, and sale of
various kinds of electronic equipment, instruments, and devices for consumer and
industrial markets. The company's principal manufacturing facilities are located
in Japan, the United States, Europe, and Asia, and its products are marketed by
sales subsidiaries and unaffiliated local distributors throughout the world. The
company also develops, produces, manufactures, and markets home-use game
consoles and software. The company is engaged in the development, production,
manufacture, and distribution of recorded music, in all commercial formats and
musical genres. The company is also engaged in the development, production,
manufacture and marketing of image-based software, including film, video, and
television. Further, the company conducts insurance operations principally
through a Japanese stock life insurance subsidiary. In addition to the above,
the company is engaged in customer financing and leasing business and has begun
to participate in new business activities including digital broadcasting,
information and communications, and others.
 
2.  Summary of significant accounting policies:
 
The parent company and its subsidiaries in Japan maintain their records and
prepare their financial statements in accordance with accounting principles
generally accepted in Japan while its foreign subsidiaries maintain their
records and prepare their financial statements in conformity with accounting
principles generally accepted in the countries of their domicile. Certain
adjustments and reclassifications, including those relating to the tax effects
of temporary differences, capitalization of stock purchase warrants, deferral of
insurance acquisition costs, the accrual of certain expenses and the accounting
for foreign currency translation, have been incorporated in the accompanying
consolidated financial statements to conform with accounting principles
generally accepted in the United States of America (U.S. GAAP). These
adjustments were not recorded in the statutory books of account.
 
                                       F-8

The preparation of financial statements in conformity with U.S. GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
Significant accounting policies are as follows:
 
Basis of consolidation and accounting for
  investments in affiliated companies -
 
The consolidated financial statements include the accounts of the parent company
and those of its majority-owned subsidiary companies. All intercompany
transactions and accounts are eliminated. Investments in 20% to 50% owned
companies are stated at cost plus equity in undistributed earnings; consolidated
net income includes the company's equity in current earnings/losses of such
companies, after elimination of unrealized intercompany profits.
 
On occasion, a subsidiary or affiliated company accounted for by the equity
method may issue its shares to third parties as either a public offering or upon
conversion of convertible debt to common stock at amounts per share in excess of
or less than the company's average per share carrying value. With respect to
such transactions, the resulting gains or losses arising from the change in
interest are recorded in income for the year the change in interest transaction
occurs.
 
The excess of the cost over the underlying net equity of investments in
subsidiaries and affiliated companies accounted for on an equity basis is
allocated to identifiable assets based on fair values at the date of
acquisition. The unassigned residual value of the excess of the cost over the
underlying net equity is recognized as goodwill.
 
Translation of foreign currencies -
 
All asset and liability accounts of foreign subsidiaries and affiliates are
translated into Japanese yen at appropriate year-end current rates and all
income and expense accounts are translated at rates that approximate those rates
prevailing at the time of the transactions. The resulting translation
adjustments are accumulated as a component of stockholders' equity.
 
Foreign currency receivables and payables are translated at appropriate year-end
current rates and the resulting translation gains or losses are taken into
income currently.
 
                                       F-9
<PAGE>   62
 
Revenue recognition -
 
Revenues from electronics, game and music sales are recognized when products are
shipped to customers.
 
Motion picture revenue is recognized beginning on the date of theatrical
exhibition. Revenue from television licensing agreements is recognized when the
motion picture or television series first becomes available for telecast.
Revenue from home videocassette sales is generally recognized on the date of
shipment.
 
Insurance premiums are reported as revenue when due from policyholders. Benefits
and expenses are associated with earned insurance premiums so as to result in
the recognition of profits over the life of the contracts. This association is
accomplished through a provision for liabilities for future benefits and
amortization of acquisition costs.
 
Cash and cash equivalents -
 
Cash and cash equivalents include all highly liquid investments, generally with
original maturities of three months or less, that are readily convertible to
known amounts of cash and are so near maturity that they present insignificant
risk of changes in value because of changes in interest rates.
 
Marketable securities -
 
Marketable securities consist of debt and equity securities. Debt securities and
equity securities designated as available-for-sale, whose fair values are
readily determinable, are carried at fair value with unrealized gains or losses
included as a component of stockholders' equity, net of applicable taxes. Debt
and equity securities classified as trading securities are carried at fair value
with unrealized gains or losses included in income. Debt securities that are
expected to be held-to-maturity are carried at amortized cost. Individual
securities classified as either available-for-sale or held-to-maturity are
reduced to net realizable value by a charge to income for other than temporary
declines in fair value. Realized gains and losses are determined on the average
cost method and are reflected in income.
 
Inventories -
 
Inventories in electronics, game and music are valued at cost, not in excess of
market, cost being determined on the "average cost" basis except for the cost of
finished products carried by certain subsidiary companies which is determined on
the "first-in, first-out" basis.
 
                                      F-10

Film costs include production, print, certain advertising costs and allocated
overhead. Film costs are amortized in the proportion that revenue for a period
relates to management's estimate of ultimate revenues.
 
Unamortized film costs are compared with estimated net realizable value on an
individual film basis and write-downs are recorded when indicated. Film costs
for motion pictures and television programs that are expected to be amortized
against revenues from primary markets are classified as current assets. Primary
markets for motion pictures include theatrical, home videocassette and pay
television. Primary markets for television programs include network and
first-run syndication. All other film costs are classified as noncurrent.
 
Property, plant and equipment and depreciation -
 
Property, plant and equipment is stated at cost. Depreciation of property, plant
and equipment is computed on the declining-balance method for the parent company
and Japanese subsidiaries and on the straight-line method for foreign subsidiary
companies at rates based on estimated useful lives of the assets according to
general class, type of construction and use. Significant renewals and additions
are capitalized at cost. Maintenance and repairs, and minor renewals and
betterments are charged to income as incurred.
 
Intangibles and goodwill -
 
Intangibles, which mainly consist of artist contracts and music catalogs, are
being amortized on a straight-line basis principally over 16 years and 21 years,
respectively.
 
Goodwill recognized in acquisitions accounted for as purchases is being
amortized on a straight-line basis principally over a 40-year period.
 
Deferred insurance acquisition costs -
 
Costs that vary with and are primarily related to acquiring new insurance
policies are deferred and are being amortized mainly over the premium-paying
period of the related insurance policies using assumptions consistent with those
used in computing policy reserves.
 
Future insurance policy benefits -
 
Future insurance policy benefits are computed based on actuarial assumptions.

Accounting for the impairment of long-lived assets -
 
The company's long-lived assets, including goodwill and identifiable
intangibles, held and used are reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of the assets may not
be recoverable. When the sum of expected future cash flows (undiscounted and
without interest charges) is less than the carrying amount of the asset, an
impairment loss is recognized, based on the fair value of the asset. The fair
value of goodwill is determined using a discounted cash flows analysis.
 
Income taxes -
 
The provision for income taxes is computed based on the pretax income included
in the consolidated statements of income. The asset and liability approach is
used to recognize deferred tax assets and liabilities for the expected future
tax consequences of temporary differences between the carrying amounts and the
tax bases of assets and liabilities.
 
Derivative financial instruments -
 
Derivative financial instruments, which include foreign exchange forward
contracts, foreign currency option contracts, interest rate swap agreements, and
interest rate and currency swap agreements, are used in the company's risk
management of foreign currency and interest rate risk exposures of its financial
assets and liabilities.
 
     Foreign exchange forward contracts:
 
     Foreign exchange forward contracts are used to limit exposure to losses,
     resulting from changes in foreign currency exchange rates, on accounts
     receivable and payable and anticipated transactions denominated in foreign
     currencies. Foreign exchange forward contracts which are designated and
     effective as hedges of such currency exchange rate risk on existing assets
     and liabilities are marked to market and included as an offset to foreign
     exchange gains/losses recorded on the existing assets and liabilities. Such
     contracts on anticipated transactions, including contracts used to hedge
     intercompany foreign currency commitments which do not qualify as firm
     commitments, are marked to market with changes in value recognized in
     foreign exchange gains/losses.
 
                                      F-12
<PAGE>   65
 
     Foreign currency option contracts:
 
     The company enters into purchased foreign currency option contracts to
     limit exposure to losses, resulting from changes in foreign currency
     exchange rates, on accounts receivable and anticipated transactions
     denominated in foreign currencies. The company also enters into written
     foreign currency option contracts, of which the majority are part of range
     forward contracts corresponding to the purchased foreign currency option
     contracts. The carrying values of all foreign currency option contracts are
     marked to market with changes in value recognized in foreign exchange
     gains/losses.
 
     Interest rate swap agreements and interest rate
       and currency swap agreements:
 
     The company enters into interest rate swap agreements or interest rate and
     currency swap agreements in order to lower funding costs, to diversify
     sources of funding and to limit the company's exposure to loss in relation
     to underlying debt instruments resulting from adverse fluctuations in
     interest rates or foreign currency exchange rates. The related interest
     differentials paid or received under the interest rate swap agreements and
     under the interest rate and currency swap agreements are recognized over
     the terms of the agreements in interest expense. Currency swap portions of
     the interest rate and currency swap agreements which are designated and
     effective as hedges of exposure to losses resulting from changes in foreign
     currency exchange rates on underlying debt denominated in foreign currency
     are marked to market and included as an offset to foreign exchange
     gains/losses on the underlying debt.
 
After an underlying hedged transaction is settled or ceases to exist, all
changes in fair value of related derivatives which have not been settled are
recognized in foreign exchange gains/losses.

Net income per share -
 
In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No.128 (FAS 128), "Earnings per
Share" (EPS), which replaces the presentation of primary earnings per share with
a presentation of basic EPS and also requires dual presentation of basic and
diluted EPS with an appropriate reconciliation of both computations. Basic EPS
is computed based on the average number of shares of common stock outstanding
during each period and diluted EPS assumes the dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock. Net income per
share is appropriately adjusted for any free distributions of common stock. FAS
128 was effective for both interim and annual periods ending after December 15,
1997. All prior-period EPS data presented have been restated to conform with FAS
128.
 
Free distribution of common stock -
 
On occasion, the company may make a free distribution of common stock which is
accounted for either by a transfer of the applicable par value from additional
paid-in capital to the common stock account or with no entry if free shares are
distributed from the portion of previously issued shares accounted for as excess
of par value in the common stock account. Under the Japanese Commercial Code, a
stock dividend can be effected by an appropriation of retained earnings to the
common stock account by resolution of the general stockholders' meeting,
followed by a free share distribution with respect to the amount appropriated by
resolution of the Board of Directors' Meeting.
 
Common stock issue costs -
 
Common stock issue costs are directly charged to retained earnings, net of tax,
in the accompanying consolidated financial statements as the Japanese Commercial
Code prohibits charging such stock issue costs to capital accounts which is the
prevailing practice in the United States of America.
 
Recent pronouncements -
 
     Comprehensive income:
 
     In June 1997, the FASB issued FAS 130, "Reporting Comprehensive Income".
     This standard requires additional disclosures in the financial statements
     for periods beginning after December 15, 1997, and will have no effect on
     the company's financial position or results of operations.

     Internal-use software:
 
     In March 1998, the American Institute of Certified Public Accountants
     issued Statement of Position (SOP) 98-1, "Accounting for the Costs of
     Computer Software Developed or Obtained for Internal Use". This SOP, which
     is effective for financial statements for fiscal years beginning after
     December 15, 1998, provides guidance on accounting for the costs of
     computer software developed or obtained solely to meet the company's
     internal needs. The company intends early adoption of the SOP in the first
     quarter of the year ending March 31, 1999. At this stage, it is not
     possible to estimate the impact of adoption on the company's financial
     statements for the year ending March 31, 1999.
 
     Derivative instruments and hedging activities (unaudited):
 
     In June 1998, the FASB issued FAS 133, "Accounting for Derivative
     Instruments and Hedging Activities". This standard, which is effective for
     fiscal years beginning after June 15, 1999, requires all derivatives to be
     recognized in the statement of financial position as either assets or
     liabilities and measured at fair value. To implement this standard, all
     hedging relationship must be reassessed. At this stage, it is not possible
     to estimate the impact of adoption on the company's financial position or
     results of operations.
 
Reclassifications -
 
Certain reclassifications of the financial statements and related footnote
amounts in the years ended March 31, 1996 and 1997 have been made to conform to
the presentation in the year ended March 31, 1998.

The basic agreements with certain banks in Japan include provisions that
collateral (including sums on deposit with such banks) or guarantors will be
furnished upon the banks' request and that any collateral furnished, pursuant to
such agreements or otherwise, will be applicable to all present or future
indebtedness to such banks.
 
10.  Insurance-related operations:
 
The company's stock life insurance subsidiary maintains accounting records as
noted in Note 2 in accordance with the accounting principles and practices
prescribed by the Japanese Ministry of Finance (the "MOF"), which vary in some
respects from U.S. GAAP. Those differences are mainly: that insurance
acquisition costs are deferred and amortized generally over the premium-paying
period of the insurance policies, that future policy benefits calculated locally
under the authorization of the MOF are comprehensively adjusted to a net level
premium method with certain adjustments of actuarial assumptions and that
deferred income taxes are not recognized under local accounting practices. For
purposes of preparing the consolidated financial statements, appropriate
adjustments have been made to reflect such items in accordance with U.S. GAAP.
 
The amounts of statutory net equity of the subsidiary as of March 31, 1997 and
1998 were 12,625 million yen and 40,625 million yen, respectively.
 
                                      F-23
<PAGE>   76
 
Deferred insurance acquisition costs -
 
Insurance acquisition costs to be deferred, such as commission expenses, medical
examination and inspection report fees, etc., vary with and are primarily
related to acquiring new insurance policies and are amortized mainly over the
premium-paying period of the related insurance policies using assumptions
consistent with those used in computing policy reserves. Amortization charged to
income for the years ended March 31, 1996, 1997 and 1998 amounted to 9,694
million yen, 15,855 million yen and 21,838 million yen, respectively.
 
Future insurance policy benefits -
 
Liabilities for future policy benefits are established in amounts adequate to
meet the estimated future obligations of policies in force. These liabilities
are computed by the net level premium method based upon estimates as to future
investment yield, mortality and withdrawals. Future policy benefits are computed
using interest rates ranging from approximately 2.75% to 6.25%, generally graded
down after 10 to 20 years. Mortality, morbidity and withdrawal assumptions for
all policies are based on either the life insurance subsidiary's own experience
or various actuarial tables. At March 31, 1997 and 1998, future insurance policy
benefits amounted to 528,204 million yen and 673,473 million yen, respectively.
 
11.  Financial instruments:
 
The company has certain financial instruments including financial assets and
liabilities and off-balance-sheet financial instruments incurred in the normal
course of business. In applying a consistent risk management strategy, the
company manages the exposure to market rate movements of its financial assets
and liabilities through the use of derivative financial instruments which
include foreign exchange forward contracts, foreign currency option contracts,
interest rate swap agreements and interest rate and currency swap agreements
designated as hedges. These instruments are executed with creditworthy financial
institutions, and virtually all foreign currency contracts are denominated in
U.S. dollars, German marks and other currencies of major countries. Although the
company may be exposed to losses in the event of nonperformance by
counterparties or interest and currency rate movements, it does not anticipate
significant losses due to the nature of its counterparties or the hedging
arrangements.
 
Following are explanatory notes regarding the financial assets and liabilities
and off-balance-sheet financial instruments.

Cash and cash equivalents, time deposits
  and notes and accounts receivable, trade -
 
In the normal course of business, substantially all cash and cash equivalents,
time deposits and notes and accounts receivable, trade, are highly liquid and
are carried at amounts which approximate fair value.
 
Notes and accounts payable, trade -
 
In the normal course of business, substantially all notes and accounts payable,
trade, are to be paid currently and their carrying amounts approximate fair
value.
 
Short-term borrowings and long-term debt -
 
The fair values of short-term borrowings and total long-term debt, including the
current portion, were estimated based on the discounted amounts of future cash
flows using the company's current incremental borrowing rates for similar
liabilities.
 
Derivative financial instruments -
 
The company utilizes foreign exchange forward contracts and foreign currency
option contracts primarily to fix the cash flow value resulting from accounts
receivable and payable and future transactions denominated in foreign currencies
in relation to the core currencies (Japanese yen, U.S. dollars, and German
marks) of the company's major operating units. Foreign exchange forward
contracts, the majority of which mature within three months, are used to hedge
this risk which is substantially associated with accounts receivable and payable
and anticipated transactions denominated in foreign currencies. The contracted
amounts outstanding at March 31, 1997 and 1998 were 756,294 million yen and
733,020 million yen, respectively. The fair values of these contracts were
estimated based on market quotations.
 
The company has entered into interest rate swap agreements and interest rate and
currency swap agreements which mature from 1998 to 2006 to reduce its exposure
to losses resulting from adverse fluctuations in interest rates or foreign
currency exchange rates on underlying debt instruments. At March 31, 1997 and
1998, the aggregate notional principal amounts of the interest rate swap
agreements were 176,705 million yen and 91,235 million yen, respectively, and
those of the interest rate and currency swap agreements were 300,269 million yen
and 430,297 million yen, respectively. The fair values of such agreements were
estimated based on the discounted amounts of net future cash flows.
 
                                      F-25
<PAGE>   78
 
The company has entered into purchased foreign currency option contracts in the
notional amounts of 196,990 million yen and 233,184 million yen at March 31,
1997 and 1998, respectively. The majority of these contracts expire within three
months of the balance sheet dates. The company has also entered into written
foreign currency option contracts in the notional amounts of 185,621 million yen
and 279,406 million yen at March 31, 1997 and 1998, respectively. The majority
of these contracts are part of range forward contract arrangements and expire in
the same month with the corresponding purchased foreign currency option
contracts described above. The fair values of such foreign currency options were
estimated based on values quoted by brokers.
 
A consolidated insurance subsidiary has entered into written government bond
option contracts as an integral part of short-term investing activities in order
to fix the yields from bonds on hand to certain ranges. All of these contracts
expire within two months of the balance sheet date and their notional principal
amounts were 204,945 million yen and 181,509 million yen at March 31, 1997 and
1998, respectively. For accounting purposes, those transactions do not qualify
for hedge accounting. Accordingly, those written bond option contracts were
marked to market. The fair values of such written bond option contracts were
estimated based on market quotations.

12.  Pension and severance plans:
 
Upon terminating employment, employees of the parent company and subsidiaries in
Japan are entitled, under most circumstances, to lump-sum indemnities or pension
payments as described below. For employees voluntarily retiring, under normal
circumstances, minimum payment is an amount based on current rates of pay and
lengths of service. In calculating the minimum payment for employees
involuntarily retiring, including employees retiring due to meeting mandatory
retirement age requirements, the company may grant additional benefits. With
respect to directors' resignations, lump-sum severance indemnities are
calculated using a similar formula and are normally paid subject to the approval
of the company's stockholders.

The parent company and most subsidiaries in Japan have contributory funded
defined benefit pension plans, which are pursuant to the Japanese Welfare
Pension Insurance Law. The contributory pension plans cover a portion of the
governmental welfare pension program, under which the contributions are made by
the companies and their employees, and an additional portion representing the
substituted noncontributory pension plans. Under the contributory pension plans,
the defined benefits representing the noncontributory portion of the plans, in
general, cover 60% of the indemnities under the existing regulations to
employees. The remaining indemnities are covered by severance payments by the
companies. The pension benefits are determined based on years of service and the
compensation amounts, as stipulated in the aforementioned regulations, are
payable at the option of the retiring employee in a lump-sum amount or on a
monthly pension. Contributions to the plans are funded through several financial
institutions in accordance with the applicable laws and regulations.
 
Most foreign subsidiaries have defined benefit pension plans or severance
indemnity plans which substantially cover all of their employees, under which
the cost of benefits is currently funded or accrued. Benefits awarded under
these plans are based primarily on current rate of pay and lengths of service.
 
Net pension and severance costs and the related pension plans' funded status
including the employees' contributory portion and rate assumptions are shown

As required under FAS 87 "Employers' Accounting for Pensions", the assumptions
are reviewed in accordance with changes in circumstances. Such changes in
assumptions are the primary reason for the fluctuation in the projected benefit
obligation and unrecognized net gains and losses.

Under FAS 87, the company has recorded a pension liability to cover the amount
of the projected benefit obligation in excess of plan assets, considering
unrealized items and the minimum pension liability. The minimum pension
liability which the company has recognized represents the excess of accumulated
benefits over plan assets and accrued pension cost. A corresponding amount was
recognized as an intangible asset to the extent of unrecognized prior service
cost, and the balance was recorded as a separate reduction of stockholders'
equity, net of tax.
 
The plan assets are invested primarily in interest bearing securities and listed
equity securities.

The company is subject to a number of different income taxes which, in the
aggregate, indicate a statutory rate in Japan of approximately 51%. Due to a
change in Japanese income tax regulations, effective April 1, 1998, the
statutory rate was reduced to approximately 48% and such amount has been used in
calculating the future expected tax effects of temporary differences. The effect
of the enacted change in the tax rate was insignificant.

The valuation allowance mainly relates to deferred tax assets of consolidated
subsidiaries with operating loss carryforwards for tax purposes that are not
expected to be realized. The net changes in the total valuation allowance for
the years ended March 31, 1996, 1997 and 1998 were increases of 28,174 million
yen, 3,902 million yen and 3,650 million yen, respectively.

At March 31, 1998, no deferred income taxes have been provided on undistributed
earnings of foreign subsidiaries not expected to be remitted in the foreseeable
future totaling 295,778 million yen, and on the gain on a subsidiary's sale of
stock of 61,544 million yen arising from the issuance of common stock of Sony
Music Entertainment (Japan) Inc. in a public offering to third parties in
November 1991, as the company does not anticipate any significant tax
consequences on possible future disposition of its remaining investment based on
its tax planning strategies. The unrecognized deferred tax liabilities as of
March 31, 1998 for such temporary differences amounted to 109,827 million yen.
 
Operating loss carryforwards for tax purposes of consolidated subsidiaries at
March 31, 1998 amounted to approximately 235,319 million yen and are available
as an offset against future taxable income of such subsidiaries. These
carryforwards expire at various dates primarily up to 15 years. Realization is
dependent on such subsidiaries generating sufficient taxable income prior to
expiration of the loss carryforwards. Although realization is not assured,
management believes it is more likely than not that all of the deferred tax
assets, less valuation allowance, will be realized. The amount of such net
deferred tax assets considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.

On November 20, 1991, the company made a free share distribution of 33,908,621
shares for which no accounting entry is required in Japan. Had the distribution
been accounted for in the manner adopted by companies in the United States of
America, 201,078 million yen would have been transferred from retained earnings
to the appropriate capital accounts.
 
Conversions of convertible debt into common stock are accounted for in
accordance with the provisions of the Japanese Commercial Code by crediting
approximately one-half of the conversion proceeds to the common stock account
and the remainder to the additional paid-in capital account.
 
The Japanese Commercial Code provides that an amount equal to at least 10% of
cash dividends and other distributions from retained earnings paid by the parent
company and its Japanese subsidiaries be appropriated as a legal reserve. The
amounts of statutory retained earnings of the parent company available for the
payments of dividends to stockholders as of March 31, 1997 and 1998 were 507,253
million yen and 555,643 million yen, respectively. These amounts include cash
dividends for the six-month periods ended March 31, 1997 and 1998, respectively,
which have been incorporated in the accompanying consolidated financial
statements.

The appropriations of retained earnings for the year ended March 31, 1998, which
have been incorporated in the accompanying consolidated financial statements,
will be proposed for approval at the general stockholders' meeting to be held on
June 26, 1998 and will be recorded in the statutory books of account, in
accordance with the Japanese Commercial Code, after stockholders' approval.
 
The ordinary general meeting of stockholders held on June 27, 1997 authorized
the company, pursuant to the Japanese regulations, to acquire and retire up to a
total not exceeding 30 million yen outstanding shares of its common stock with
its profit, on and after June 28, 1997, whenever deemed necessary by the Board
of Directors in view of general economic conditions, the company's business
performance and financial condition and other factors. At March 31, 1998, no
common stock had been acquired under this authorization.
 
On May 7, 1998, the company's Board of Directors resolved the following
proposals to be approved by the general stockholders' meeting to be held on June
26, 1998. The proposals resolve that (a) in addition to the shares discussed in
the preceding paragraph, on and after June 27, 1998, the company may, by a
resolution of the Board of Directors, acquire and retire up to a total not
exceeding 30 million yen outstanding shares of its common stock with its
additional paid-in capital at prices in total not exceeding 400 billion yen and
(b) the company may grant share subscription rights to directors and/or
employees pursuant to the Japanese regulations.
 
In February 1998, the company adopted a cash stock appreciation rights plan (the
"SARs") as an incentive plan for selected employees. Under the terms of the
plan, the SARs may be exercised during the period from 1999 until 2004. No
compensation expense was recognized for the SARs in the year ended March 31,
1998 as the company's stock price did not exceed the strike price of the SARs.
 
Retained earnings at March 31, 1998 include parent company and its consolidated
subsidiaries' equity in undistributed earnings of 20% to 50% owned companies
accounted for by the equity method in the amount of 18,566 million yen.

19.  Events (unaudited) subsequent to the date
       of the report of independent accountants:
 
In May 1998, Loews Theatres Exhibition Group (Loews Theatres), a unit of Sony
Pictures Entertainment (SPE), and Cineplex Odeon Corporation, a Canadian theatre
chain, combined and created Loews Cineplex Entertainment Corporation. In
conjunction with the combination, the company received approximately 53.6
billion yen in cash from the repayment of all of the intercompany debt of Loews
Theatres, which was refinanced with third party debt, and receipt of a dividend.
As a result of the combination, SPE and certain of its subsidiaries owned 51.1%
(representing 49.9% of the voting shares) of Loews Cineplex Entertainment
Corporation. After giving effect to the public offering of shares of common
stock of Loews Cineplex Entertainment Corporation in August 1998, SPE and
certain of its subsidiaries currently own 38.5% of Loews Cineplex Entertainment
Corporation. The new company has been deconsolidated and the company accounts
for it on the equity basis for the fiscal year ending March 31, 1999. The
revenues and operating income of Loews Theatres for the fiscal year ended March
31, 1998 were approximately 56.3 billion yen and 2.5 billion yen, respectively.
In addition, the company recorded a gain of approximately 4.8 billion yen on the
combination in the first quarter ended June 30, 1998.
 
On August 12, 1998, SPE, together with certain partners, completed the
acquisition of Telemundo Group, Inc. (Telemundo), one of two Spanish-language
television broadcast companies currently operated in the United States. Through
a series of transactions, SPE now owns 50% of a newly formed company holding
Telemundo's network operations and 24.95% of an entity holding Telemundo's
station operations, including seven full-power UHF stations. SPE's initial
capital investment totaled approximately 15.1 billion yen.
