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 May 13, 2002, Reliant Resources, Inc. ("RRI"), a majority-owned subsidiary of Reliant Energy, Incorporated ("REI"), announced its preliminary findings of its review of certain trading transactions involving simultaneous purchases and sales with the same counterparty at the same price. While RRI is still completing a review of its trading transactions, it believes that it has engaged in transactions that had the effect of increasing its revenues by approximately 10% over the years 1999, 2000 and 2001. The management of RRI and REI, as well as their accounting and legal resources, have been very involved in the review of these transactions and RRI's accounting policies. For the reasons set forth herein, and because the attention of the relevant personnel that prepare REI's and RRI's Form 10-Q has been diverted from that task, REI is not able to timely file its Form 10-Q without unreasonable or undue effort, expense or burden. -2-
