PART II - RULES 12b-25(b) AND (c) [X] If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate) (a) The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense; (b) The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q, or portion thereof will be filed on or before the fifth calendar day following the prescribed due date; and (c) The accountant's statement or other exhibit required by Rule 12b-25(c) has been attached if applicable. PART III - NARRATIVE State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, or the transition report or portion thereof, could not be filed within the prescribed time period. On February 5, 2002, Reliant Energy, Incorporated (the "Company") announced that it would be restating its earnings for the second and third quarter of 2001, and that as a result of the restatement, it would be delaying the release of its fourth quarter and year 2001 earnings. The restatement related to a correction in the accounting treatment for a series of four structured transactions that were inappropriately accounted for as cash flow hedges for the period of May 2001 through September 2001, rather than as derivatives with changes in fair value recognized through the income statement. The Company's management, as well as its accounting and legal resources, were very involved in the restatement process through mid-March 2002, at which time the Company released its fourth quarter and year 2001 earnings. As part of the restatement, these resources were also focused on amending the Quarterly Reports on Form 10-Q for the quarters ended June 30, 2001 and September 30, 2001, as well as preparing and filing numerous reports with the Securities and Exchange Commission that were related to the restatement, rather than on preparing the Annual Report on Form 10-K for the year ended December 31, 2001 (the "Form 10-K"). For the reasons set forth herein, and because the attention of the relevant personnel that prepare the Form 10-K was diverted from that task, the Company is not able to timely file its Form 10-K without unreasonable or undue effort, expense or burden. -2-
