Item 5. Other Information

On February 13, 2002, the Federal Energy Regulatory Commission (FERC) issued an order commencing a fact-finding investigation of potential manipulation of electric and natural gas prices in California energy markets. On May 8, 2002, the FERC requested data and information with respect to certain trading strategies that companies may have engaged in. Specifically, the requests inquired as to whether or not certain trading strategies were the same or similar to those of Enron Corporation and its affiliates. This request was made to all sellers of wholesale electricity and/or ancillary services to the California Independent System Operator and/or the California Power Exchange during the period 2000 and 2001, including Avista Corporation and Avista Energy.

On May 22, 2002, Avista Corporation and Avista Energy filed their responses to this request. In their responses, Avista Corporation and Avista Energy deny improper California trading activities. Avista Corporation’s press release is filed as exhibit 99(a).
