Box 660164 * Dallas, Texas 75266-0164 214-777-1277 Becky Hall Director, Investor Relations April 3, 1997 Dear Financial Community, On March 31, 1997, the Public Utility Commission of Texas (PUCT) issued a Final Order that lowered the retail base rates of Central Power and Light Company (CPL) by approximately $27 million from the level existing prior to CPL placing into effect higher bonded rates in May 1996. The PUCT also ordered CPL to lower its rates by an additional $16 million in 1998 and another $16 million in 1999. In addition, rate case expenses are currently scheduled for hearing on April 14, 1997 with a final order due no later than May 30, 1997. The financial impact of the Final Order is currently being analyzed. We plan to provide the financial impact of the rate order as soon as the effect has been determined. The following information is based upon CPL's preliminary review of the PUCT final order, PUCT staff's workpapers and CPL's understanding of relevant underlying assumptions in those documents and materials.
