Previously, on August 3, 2001, Trend Micro announced its Japanese GAAP financial
information for the same period. Significant differences between Japanese GAAP
and U.S. GAAP applicable to Trend Micro are summarized below.
Goodwill write-off (2,000 million yen), which is recognized as other expenses
under Japanese GAAP, is recognized as operating expenses under U.S. GAAP.
From the fiscal year ending December 31, 2001, Trend Micro and Trend Micro
Incorporated (Taiwan) have adopted the deferred revenue accounting for their
Post-contract Customer Support service for its Japanese GAAP financial reporting
purposes. The cumulative effect of adopting the deferred revenue accounting of
3,009 million yen is recorded as other expenses under Japanese GAAP. For its
U.S. GAAP reporting purposes, Trend Micro and Trend Micro Incorporated (Taiwan)
have historically adopted the deferred revenue accounting for their Post-
contract Customer Support service on a consistent basis.

                  NOTES TO CONSOLIDATED FINANCIAL INFORMATION
                  -------------------------------------------

                                  (Unaudited)

1.    Basis of presentation

     The consolidated financial information of Trend Micro Incorporated and its
subsidiaries (collectively "the Company") are unaudited. The financial
information has been prepared in accordance with U.S. GAAP. The unaudited
financial information furnished include all adjustments that are, in the opinion
of management, necessary to a fair statement of the results for the interim
periods presented. Operating results for the six months ended June 30, 2001 are
not necessarily indicative of the results for the year ended December 31, 2001.

2.    Recent pronouncements

     From the fiscal year beginning January 1, 2001, The Company adopted FAS
No. 133 "Accounting for Derivative Instruments and Hedging Activities" as
amended by FAS No. 138 "Accounting for Certain Derivative Instruments and
Certain Hedging Activities - an Amendment of FASB statement No. 133". FAS No.
133, as amended, establishes accounting and reporting standards for derivative
instruments. Specifically, FAS No. 133 requires an entity to recognize all
derivatives as either assets or liabilities in the balance sheet and to measure
those instruments at fair value. Additionally, the fair value adjustments will
affect either stockholders' equity or net income depending on whether the
derivative instrument qualifies as a hedge for accounting purposes and, if so,
the nature of the hedging activity. The adoption of FAS No. 133 did not have an
effect on the Company's financial position and results of operations.

     In July 2001, the Financial Accounting Standards Board issued FAS No. 141
"Business Combinations" and FAS No. 142 "Goodwill and Other Intangible Assets."
FAS No. 141 supersedes Accounting Principles Board Opinion ("APB") No. 16
"Business Combination" and FAS No. 38 "Accounting for Preacquisition
Contingencies of Purchases Enterprises." Under FAS No. 141, all business
combinations are required to be accounted for under a single method, the
purchase method. This new statement prohibits the use of the pooling-of-interest
method, which was previously permitted under APB No. 16, for business
combinations initiated after June 30, 2001. FAS No. 141 also established
criteria for the separate recognition of intangible assets acquired in a
business combination. FAS No. 142 supersedes APB No. 17 "Intangible Assets."
This new statement requires that goodwill no longer be amortized to earnings,
but instead be subject to periodic testing for impairment. FAS No. 142 is
effective for fiscal years beginning after December 15, 2001, with earlier
application permitted only in specified circumstances. The Company believes that
the adoption of FAS No. 141 and FAS No. 142 will not have a material effect on
the financial statements of the Company.

     In July 2001, the Financial Accounting Standards Board issued SFAS No. 143
"Accounting for Asset Retirement Obligations" ("FAS 143"). FAS No. 143 requires
the recognition of a liability for an asset retirement obligation in the period
in which it is incurred. When the liability is initially recorded, the carrying
amount of the related long-lived asset is correspondingly increased. Over time,
the liability is accreted to its present value and the related capitalized
charge is depreciated over the useful life of the asset. FAS No. 143 is
effective for fiscal years beginning after June 15, 2002. The Company is
evaluating the effect of the new standard on its financial position and results
of operations.

3.    U.S. dollar amounts

     U.S. dollar amounts presented in the financial information are included
solely for the convenience of the reader. These translations should not be
construed as representations that the yen amounts actually represent, or have
been or could be converted into, U.S. dollars. As the amounts shown in U.S.
dollars are for convenience only, the approximate current rate at June 29, 2001
((Yen)125.00 = U.S. $1) has been used for the purpose of presentation of the
U.S. dollar amounts in the accompanying consolidated financial information.

4.    Stock split

On February 15 2001, the Board of Directors of the Company decided and declared
a stock split in the ratio of two-for-one for which the record date was May 18,
2001. All prior share and per share amounts in the financial information and
accompanying notes have been restated to reflect this stock split.

5.    Net income per share

     Net income per share amounts were computed based on Statements of Financial
Accounting Standards No. 128. For the six months ended June 30, 2000 and 2001,
weighted average shares used for computation of basic net income per share were
130,011 thousand shares and 131,340 thousand shares, respectively, and the
weighted average shares used for diluted net income per share were 133,810
thousand shares and 133,676 thousand shares, respectively. The weighted average
shares outstanding for diluted net income per share calculation were increased
to include additional shares from the assumed exercise of stock warrants and
options which had dilutive effect.

vesting period which is generally 24 months. Approximately (Yen)397,467
thousand, (Yen)379,803 thousand and (Yen)101,528 thousand was amortized during
fiscal 1998, 1999 and 2000 respectively. The grants of October 17, 1997, July
29, 1999, June 26, 2000 March 19, 2001 and June 4, 2001 with respect to which

14.  Impairment of ipTrend Investment

In February 2000, the company acquired a controlling interest in ipTrend
Incorporated ("ipTrend"). ipTrend effectively became a wholly owned subsidiary
in November 2000, when the remaining minority interest was acquired. The total
purchase price was (Yen)2,800,000 thousand and (Yen)2,527,636 thousand was
allocated to goodwill. Recently, the company undertook a revaluation of its
investment in ipTrend and related business strategy and determined that the
investment was impaired. On August 3, 2001, the company approved the sale of the
main business of ipTrend to IPSQUARE, an unrelated third party, and subsequently
commenced liquidation of the subsidiary. Although a definitive agreement has not
been agreed between the parties, the company does not expect a significant gain
or loss on the sale of the business, apart from the goodwill write-off of
(Yen)2,253,559 thousand ($18,028 thousand). Goodwill amortization of (Yen)95,797
thousand and the write off of (Yen)2,253,559 thousand ($18,028 thousand) are
included in operating income for the six months ended June 30, 2000 and 2001,
respectively.
