OTHER EVENTS On May 19, 2003, Sierra Pacific Resources ("SPR"), the parent corporation of Sierra Pacific Power Company (the "Company"), issued a press release announcing that the Public Utilities Commission of Nevada ("PUCN") approved the previously-announced stipulated agreement that gives electric ratepayers served by the Company in northern Nevada a rate decrease of $9.8 million, or an overall 1.4 percent decrease, beginning June 1, 2003. The agreement reached by SPR, the staff of the PUCN, the State Attorney General's Bureau of Consumer Protection, and a coalition of major utility customers also calls for a rate decrease of $19.8 million, or an overall 2.7% decrease, the following year, commencing June 1, 2004. The agreement was filed with the PUCN last week as the PUCN was due to begin hearings in the Company's annual deferred energy case. The stipulated agreement also included the following significant provisions: - - The Company will reduce its deferred energy balance by $45 million dollars, from a balance of approximately $15.4 million collectible from customers to a balance of approximately $29.6 million payable to customers. This will result in an after tax write-off of approximately $29.3 million for the Company. - - The Company will discontinue accruing carrying charges on deferred energy balances that it is already collecting from customers and on the $29.6 million amount payable to customers as a result of this decision. - - The Company's base tariff energy rate will remain at the rate currently in effect. - - Contingent contract termination payments are deferred for consideration to a future Company filing. - - All parties to the stipulation agree to commence discussions no later than July 1, 2003, to address the merits of performance based ratemaking. - - The parties have consented to the dismissal of the civil cases on file with the First Judicial District Court in Nevada that address the PUCN decision on the Company's previous deferred energy filing. A copy of the press release, dated May 19, 2003, is attached as Exhibit 99.1 hereto. ITEM 7.
