Description of the change of the recognition policy

Until the end of FY 2000, the Company (Japan) and Trend Micro Incorporated (Taiwan) booked revenue for Premium Support and other post-contract customer support services at the beginning of the support period. Effective from FY 2001, the method of recognizing this revenue recognition has been changed and sales revenues from customer support are deferred over the relevant support period. Under Japanese GAAP, Trend Micro is not required to restate its financial statements because of a change in its revenue recognition policy and has chosen not to do so in this case.

Financial Outlook

Trend Micro expects consolidated net revenue for the fiscal year 2002 of 40,000 million yen, ordinary income of 13,000 million yen and net income of 7,300 million yen. For the first quarter of the fiscal year 2002, the company estimates consolidated net revenue will be between 8,500 million yen and 9,100 million yen, ordinary income between 2,300 million yen and 2,700 million yen and net income between 1,300 million yen and 1,500 million yen.
