Informatica discovered the error, which had been applied consistently since the fourth quarter of 1999, in the course of responding to the SEC's review of the Form S-3 Registration Statement filed October 14, 2003 in connection with the acquisition of Striva Corporation. Immediately upon discovery, Informatica reviewed this matter with the SEC and began applying the proper allocation methodology for the fourth quarter 2003. License revenues generated during the fourth quarter of 2003 were properly recorded at $27.4 million before the net cumulative impact of the error from prior periods. The net cumulative impact over the four plus year period and the impact for any quarter or annual period are not material. Informatica will not be amending any of its periodic reports already filed with the SEC or revising any results prior to 2003. As a result of discussions with the SEC staff, and since Informatica has not yet filed its 2003 Form 10-K, Informatica is adjusting certain of its previously announced results of operations for the quarters and fiscal year 2003 to reflect the impact of the error in the allocation of revenue during 2003, and the cumulative impact of the correction for previous periods. The adjustments to the previously announced 2003 quarterly results will be reflected in the notes to Informatica's consolidated financial statements for the year ended December 31, 2003 to be filed on Form 10-K. The correction to the allocation methodology and the resulting adjustments will not impact Informatica's current guidance for revenue and earnings for the first quarter or fiscal year 2004. The impact of the error is detailed in the attached table. In the event that there are additional questions in connection with this matter, Informatica will be holding a conference call today beginning at 2:30 p.m. PST. A live Webcast of the conference call will be available at http://www.informatica.com/investor. A replay of the call will also be available by dialing 617-801-6888, reservation number 67141446. This press release contains forward-looking statements regarding the Company's guidance for revenue and earnings for the first quarter of 2004 and the year ended December 31, 2004. Factors that could cause actual results to differ materially include uncertainty regarding the pace of IT capital spending, the level of demand for the Company's products, the integration of the Company's recent acquisition of Striva Corporation with the rest of the Company's operations, risks associated with rapid technological change, as well as additional risk factors described in the Company's annual report on Form 10-K for the year ended December 31, 2002 and updated in the Company's report on Form 10-Q for the quarter ended September 30, 2003. The Company assumes no duty to update the information in this release.
