1.  Projected consolidated net income per share for the current fiscal year :  13.69 yen


Supplementary information on the results (January 1, 2001 through June 30, 2001)

     The Company's sales revenues are mainly derived from licensing of its
products, upgrading of its products and patterns files and post-contract support
including customer support. Until the end of FY 2000, the Company and Trend
Micro Incorporated (Taiwan) had recognized sales revenues from customer support
(which was included in post-contract support) at the beginning of the relevant
support period. Effective from FY 2001, the method of the revenue recognition
has been changed and sales revenues from customer support are deferred through
Deferred revenue under Current liabilities and Non-current liabilities over the
relevant support period.

     For convenience of comparison, the results for the year ending June 30,
2001, are presented in two ways. Results based on the accounting policies
applied from the first half of consolidated fiscal year, assumed results based
on the accounting policies applied until the previous consolidated fiscal year
and its differential are stated in the table below.

2.  Management Policy and Business Results

Trend Micro Group's Basic Management Policy
-------------------------------------------

   Since its founding, Trend Micro has provided "peace of mind" to all users of
computer networks and the Internet by offering anti-virus and Internet content
security solutions. Upholding the slogan "Your Internet VirusWall," we have
become a reliable partner to both corporate users and individual customers,
working to block computer viruses, SPAM (unwanted e-mail) and malicious codes
(harmful programs created in such programs as JAVA and Active X), as well as to
protect users from offensive URLs. We continue to contribute to the development
of the networked society in Japan and globally by offering network security
solutions and devices. We believe that our ongoing efforts to protect users'
computer systems and expand our global client base will lead to an increase in
shareholders' value.

Basic Policy on the Distribution of Profits
-------------------------------------------

   Although Trend Micro has steadily increased its profits in the past few
years, we believe that the Internet security market has only begun its
full-fledged expansion and that our market share has not stabilized in relation
to our U.S. competitors. Our larger rivals may well concentrate their management
resources to further enlarge their market share. Since our business areas are
more concentrated on anti-virus solutions than other competitors with
diversified Internet security solutions, we also face the possibility of larger
profit fluctuations in the short term.

   In this business environment the most critical management challenges are to
strengthen our financial structure and management foundation and aggressively
develop new business operations in order to maintain our competitiveness in the
market. Our priority, therefore, is to accumulate reserves, which means
withholding dividends for the time being. These reserves will be continuously
invested in research and development, an area that needs to be further
strengthened.

Medium and Long-Term Management Strategy
----------------------------------------

   Corporate IT investment has plateaued with the slowdown in the U.S. and
European economies. Chilled by this decrease in IT investment, the business
climate surrounding Trend Micro is not bright. However, we expect network
security solutions, including anti-virus measures, to continue gaining in
importance, as more and more corporate users become dependent on using networks,
and their systems' problems consequently subject them to huge losses, both in
financial terms and opportunity costs. Thus the network security market is
expected to grow steadily in the medium-to-long term. To take advantage of this
opportunity, we are focusing on maintaining our competitive edge against major
U.S. rival companies and expanding our global market share. Utilizing our global
resources and networks spanning the United States, Europe and Taiwan, we will
continue to strengthen our sales channels, improve brand awareness and corporate
image and accelerate the development of products that meet customer needs.

   The IT industry is evolving rapidly in conjunction with its constantly
changing technology. The next generation of Internet-related technologies,
including broadband, mobile communications and open platforms such as Linux,
will likely bring about dramatic changes in the network environment. We must
seize the opportunities afforded by this high-paced technological evolution, in
advance of our major U.S. competitors, while strengthening our management
structure and further increasing our operational efficiency.

Summary of Consolidated Financial Results for the First Half of FY2001
----------------------------------------------------------------------

   The six-month period under review saw a slowdown in demand within the IT
industry, primarily the result of declining corporate IT spending in Japan,
Europe and the United States. The corporate spending cuts also put the damper on
demand for network security solutions, which have been positioned as a high
priority in IT investment. Although the business environment has been harsh and
we expect some ups and downs in the short term, we believe the network security
market will enjoy steady growth over the medium and long term, as corporations
continue to increase IT investment in advanced networks and the renewal of core
business systems.

   The demand for sophisticated, specialized security solutions has risen as
corporations combat the disturbing spread of computer viruses and unauthorized
access tools programmed by hackers. Last year malicious viruses, including MTX,
HYBRIS and MAGISTR, reportedly infected many systems, while such harmful
programs as Worm and Trojan Horse were also deployed to wreak damage. At the
same time, we have begun seeing more cases in which hackers have gained access
to systems by using computerviruses. As the line begins to blur between
antidotes to viruses and protection against unauthorized access, demand is
growing for more comprehensive security measures.

   During the first half of FY2001, Trend Micro significantly increased
contracts for its Virus Buster Corporate Edition (Office Scan), winning not only
large companies but also medium and small companies. Sales of InterScan, our
anti-virus software for Internet servers, rose steadily, in response to the more
frequent virus infections spread via e-mail.


As a highly specialized anti-virus solutions provider, we have pioneered
post-contract support services, called "Premium Support," introducing them
before our major competitors in the industry. This service is in response to the
trend among large corporate users to select a vendor based not only on the
performance of its anti-virus software but also on the quality of support the
vendor offers during the license period to swiftly alert customers to new
viruses. In our outsourced Internet service operations, we were able to team up
with additional ISPs (internet service providers) to expand our client base for
anti-virus solutions, despite the inhospitable business environment for ISPs and
the entire telecommunications industry.

We made a crucial strategic move in reorganizing our security appliance server
operations, which had been handled by our subsidiary ipTrend Incorporated. This
unit faced fundamental problems in building a solid client base of small- and
medium-sized companies for its Linux- and Unix-based security appliance servers,
as these smaller companies have been hit the hardest by Japan's economic slump.
IpTrend's Linux and Unix hardware-related technology has played an important
role in the development of our next-generation anti-virus product for consumers,
Gatelock, and continues to be a crucial part of our group. However, the
company's ipStax security appliance server business for small- and medium-sized
companies urgently needed a restructuring review. We decided to dissolve ipTrend
and integrate its operations into Trend Micro, while strategically reorganizing
its operations and utilizing its technology in our anti-virus products. This
integration and reorganization resulted in our writing off the entire goodwill
of 2,000 million yen as a one-time amortization charge during the first half of
FY2001. This goodwill had been recognized as a portion of the purchase price
when we acquired ipTrend (formery Nippon Unisoft).

Starting with the first quarter of FY2001, Trend Micro (Japan) and Trend Micro
Incorporated (Taiwan) changed their accounting method for revenues from
post-contract support services. Sales revenues for these services had been
booked at the beginning of the support period; the new method defers the
recognition of sales revenues from support services and recognizes as revenue
over the support period. This new accounting treatment will reflect these
transactions more accurately, and has been applied to all our financial filings
with the Securities and Exchange Commission (SEC), including our Form 20-F
filing, which was submitted on June 29, 2001. The conversion to deferred revenue
recognition resulted in an extraordinary loss of 3,009 million yen for our
half-year results.

During the first half of FY2001, Trend Micro posted consolidated sales of 12,939
million yen, an increase of 34.8 percent over the same period last year.
Consolidated ordinary income increased 1.1 percent to 3,004 million yen, while
net loss resulted 1,376 million yen.
Sales in all geographical areas grew steadily during the first half of FY2001.
Sales in Japan posted an increase of 66.1 percent to 7,540 million yen, while
operating income from these sales rose to 4,725 million yen, up 92.7 percent
from the comparable period in FY2000. U.S. sales increased 37.3 percent to 4,899
million yen, with operating income totaling 302 million yen, a 76.9 percent
decrease. In Europe, sales increased 49.6 percent to 2,804 million yen, and
operating loss resulted 46 million yen. Taiwan sales increased 61.2 percent to
1,963 million yen, with operating losses of 28 million yen. Other areas posted
combined sales of 789 million yen, a 48.1 percent increase, and operating income
of 17 million yen, down 85.6 percent.

Prospects for FY2001
--------------------

   We expect the economies of Japan, Europe and the United States to continue
their sluggish performance in 2001, further restraining corporate spending on
IT. While the near-term business environment is expected to be bleak, we believe
corporate investment in network security solutions will continue to expand over
the medium and long term. The earnings estimates for FY2001 that follow are
based on a steady upward demand for network security despite the harsh economic
environment.

Consolidated sales: 29,000 million yen(+ 32.8 %)
Consolidated ordinary income: 8,200 million yen(+ 12.0 %)
Consolidated net income: 1,800 million (- 61.9 %)
Earnings projections are calculated based on estimated major currency exchange
rates of $1 = 115 yen and 1 EUR = 105 yen.

                                                  (3) Change in revenue recognition method for Post Contract Customer Support
                                                      Service (PCS)

                                                      Basically, The product license agreement, which the parent company and its
                                                      subsidiaries contract with the end-user, states the article for PCS (customer
                                                      support and upgrading of products and its pattern files).

                                                      Until previous consolidated fiscal year, whole revenue of the parent company
                                                      and Trend Micro Incorporated (Taiwan) applied to each product license
                                                      agreement including a portion of PCS revenue had been recognized when the
                                                      license is delivered to user. Effective current consolidated fiscal year, the
                                                      revenue recognition method for portion of PCS has changed as follows. Portion
                                                      of PCS revenue is recognized separately from total revenue and it is deferred
                                                      as Deferred revenues under Current liabilities and Non-current liabilities
                                                      based on contracted period. Deferred revenue is finally recognized for the
                                                      contracted period evenly.

                                                      As per the tendency of the parent company and Trend Micro Incorporated
                                                      (Taiwan) that the ratio of site license products revenue (to corporation user)
                                                      is getting larger than as before compare with package products revenue (to
                                                      private user), the ratio of a portion of PCS revenue is increased. As the
                                                      result of the above, the companies adopt new revenue recognition policy on
                                                      PCS, in order to recognize proper periodic profits and losses accurately. On
                                                      the other hand, there is no change for the recognition by the subsidiaries in
                                                      USA and Europe, the policy has been applied in the past and carried it over
                                                      for those subsidiaries.

                                                      According to the above change, PCS revenue (3,009,009 thousand yen), which
                                                      should be deferred by the parent company and Taiwan subsidiary as of the
                                                      beginning of the current fiscal year applied to the prior year's revenues, is
                                                      stated as Losses on prior year adjustment under Unusual losses at the first
                                                      half of current consolidated period. Effect of change in method resulted in
                                                      decrease of Sales, Operating income and Ordinary income by 492,660 thousand
                                                      yen and in increase of losses before taxes by 3,501,670 thousand yen.

                                                      The effect on segment information is described in (Segment Information).

     Basic policies for derivative transactions

     A corporate policy of Trend Micro Group does not engage in derivative
transactions. However, the interest cap trading and the interest rate swap had
been made by ipTrend Incorporated (Tokyo, Chuo-ku), during fiscal year 2000,
before the company's acquisition. These transactions had been made to avoid
risks for interest rate fluctuation. The borrowing applied to the hedge was paid
completely, when ipTrend Incorporated became a consolidated subsidiary.
Although, these transactions are not in completion as of June 30, 2001, the
company expects them to be settled with high degree of certainly. Trend Micro
Group has no intention of changing. The contractor for the interest cap trading
and the interest rate swap is the financial institution, which is trustworthy
institution. No expectation is required for future losses because of any
defaults.

(Significant subsequent events)

Members of the Trend Micro, Inc. board meeting on August 3, 2001 decided to
transfer the business of the consolidated subsidiary ipTrend Inc (Chuo-ku,
Tokyo) (100% Trend Micro controlling share) to Trend Micro and to IPSQUARE Inc
(no human or capital relation to Trend Micro); the board also decided to
commence dissolution and liquidation procedures of ipTrend (Chuo-ku). As for
ipTrend (Taiwan), a 99.9%-owned subsidiary of ipTrend (Chuo-ku) and a
consolidated subsidiary of Trend Micro, all the business will be transferred to
Trend Micro (Taiwan) (99.9% Trend Micro controlling share) and will be
liquidated.

1    Corporate profile of ipTrend Inc. (Chuo-ku, Tokyo)
     Address: 2-13-9 Ningyo-cho, Nihonbashi, Chuo-ku, Tokyo, Japan
     Representative: Mahendra Negi
     Business description: Providing Internet platform-related products and
     services
     Capital: 218 million yen
     Acquisition value of the shares: 2.8 billion yen
2    Business, properties, and liabilities to be transferred
     2.1  IPSQUARE Inc.
          Real-time OS Project and equipment, works in progress, and sales
          deposits involved in the project
     2.2  Trend Micro, Inc.
          All business and properties other than those mentioned above and the
          same amount of liabilities (Trend Micro will take over all the
          liabilities from third persons.)
3    Transfer price
     Transfer price will be calculated by the fair market value on the day of
     transfer.
4    Business transferring schedules
     Business transfer contracted on August 3, 2001
     Business transfer to be implemented by August 31, 2001
5    Dissolution date: September 3, 2001
6    Completion date for liquidation: December 2001
7    Reasons for dissolution and liquidation:
     To restructure the operations of ipTrend and improve efficiency of the
     group because the market of appliance servers for small and medium-sized
     businesses has not expanded fast enough.
8    Influence on Trend Micro in terms of consolidated business results
     8.1  The consolidated adjustment account incurred by acquisition of
          ipTrend's stock has been added up to intangible fixed assets and
          extinguished evenly for five years. With the decision of dissolution
          and liquidation, the unamortized balance of two billion yen will be
          extinguished across the board, and added up as an extraordinary loss
          during Trend Micro's interim consolidated fiscal period.
     8.2  It is expected that the influence on consolidated business results of
          Trend Micro by partial transfer of business of ipTrend (Chuo-ku) to
          IPSQUARE should be minor.

Supplementary information on the results (January 1, 2001 through June30, 2001)

The Company's sales revenues are mainly derived from licensing of its products,
upgrading of its products and patterns files and post-contract support including
customer support. Until the end of FY 2000, the Company had recognized sales
revenues from customer support (which was included in post-contract support) at
the beginning of the relevant support period. Effective from FY 2001, the method
of the revenue recognition has been changed and sales revenues from customer
support are deferred through Deferred revenue under Current liabilities and
Non-current liabilities over the relevant support period.

For convenience of comparison, the result for the year ending June 30, 2001, are
presented in two ways. Result based on the accounting policies applied from the
first half of fiscal year, assumed result based on the accounting policies
applied until the previous fiscal year and its differential are stated in the
below.

                                                        employees.

                                                        The Company has adopted incentive plans where warrants to purchase parent

                                                        all of the warrants. Compensation costs are measured at repurchase costs of

                                                  (3)   Change of policy and method of revenue recognition for PostContract
                                                        Customer Support Service (PCS)

                                                        Basically, The product license agreement, which the company contract with
                                                        the end-user, states the article for PCS (customer support and upgrading of
                                                        products and its pattern files).

                                                        Till previous fiscal year, whole revenue of the company applied to each
                                                        product license agreement including a portion of PCS revenue had been
                                                        recognized when the license is delivered to user. From the first half of
                                                        current fiscal year, the revenue recognition method for portion of PCS is
                                                        changed as follows. Portion of PCS revenue is recognized separately from
                                                        whole revenue and it is deferred as Deferred revenues under Current
                                                        liabilities and Non-current liabilities based on contracted period. Deferred
                                                        revenue is finally recognized for the contracted period evenly.

                                                        As per the tendency of the company that the ratio of site license products
                                                        revenue (to corporation user) is getting larger than as before compared with
                                                        package products revenue (to private user), the ratio of a portion of PCS
                                                        revenue is increased. As the result of the above, the companies adopt new
                                                        revenue recognition policy on PCS, in order to recognize proper periodic
                                                        profits and losses accurately.

                                                        According to the above change, PCS revenue 2,800,962 thousand yen, which
                                                        should be deferred by the company as of the beginning of the current fiscal
                                                        year applied to the prior year's revenues, is stated as Losses on prior year
                                                        adjustment under Unusual losses at the first half of current period. And it
                                                        resulted in a decrease of Operating income and Ordinary income by 545,816

(2) FY 2001 (As of June 30, 2001)

Subsidiaries and affiliaties : No fair market value



(Significant subsequent events)

Members of the Trend Micro, Inc. board meeting on August 3, 2001 decided to
transfer the business of the consolidated subsidiary ipTREND Inc (Chuo-ku,
Tokyo) (100% Trend Micro controlling share) to Trend Micro and to IPSQUARE Inc
(no human or capital relation to Trend Micro); the board also decided to
commence dissolution and liquidation procedures of ipTREND (Chuo-ku). As for
ipTREND (Taiwan), a 99.9%-owned subsidiary of ipTREND (Chuo-ku) and a
consolidated subsidiary of Trend Micro, all the business will be transferred to
Trend Micro (Taiwan) (99.9% Trend Micro controlling share) and will be
liquidated.

1    Corporate profile of ipTREND Inc. (Chuo-ku, Tokyo)
     Address: 2-13-9 Ningyo-cho, Nihonbashi, Chuo-ku, Tokyo, Japan
     Representative: Mahendra Negi
     Business description: Providing Internet platform-related products and
     services
     Capital: 218 million yen
     Acquisition value of the shares: 2.8 billion yen
2    Business, properties, and liabilities to be transferred
     2.1  IPSQUARE Inc.
          Real-time OS Project and equipment, works in progress, and sales
          deposits involved in the project
     2.2  Trend Micro, Inc.
          All business and properties other than those mentioned above and the
          same amount of liabilities (Trend Micro will take over all the
          liabilities from third persons.)
3    Transfer price
     Transfer price will be calculated by the fair market value on the day of
     transfer.
4    Business transferring schedules
     Business transfer contracted on August 3, 2001
     Business transfer to be implemented by August 31, 2001
5    Dissolution date: September 3, 2001
6    Completion date for liquidation: December 2001
7    Reasons for dissolution and liquidation:
     To restructure the operations of ipTREND and improve efficiency of the
     group because the market of appliance servers for small and medium-sized
     businesses has not expanded fast enough.
8    Influence on Trend Micro in terms of business results
     8.1  With the business transfer, dissolution, and liquidation of ipTREND
          with excessive liabilities as of June 30, 2001, the loan from Trend
          Micro is expected to be abandoned. Accordingly, 370 million yen will
          be added up as an allowance for doubtful accounts, and the whole value
          of the stock of ipTREND (2.8 billion yen) will be written down, which
          will be added as an extraordinary loss in this interim fiscal period.
     8.2  It is expected that the influence on business results of Trend Micro
          by partial transfer of business of ipTREND should be minor.
