Other Events CILCORP Inc. (the Company), a holding company, is the parent of Central Illinois Light Company (CILCO). CILCO is a public utility under the laws of the State of Illinois and, as such, is subject to regulation by the Illinois Commerce Commission (ICC) and the Federal Energy Regulatory Commission. On December 12, 1994, the ICC issued a rate order designed to grant CILCO a $10.6 million, or 6.7%, annual increase in base rate gas revenues. The order represents approximately 75 percent of CILCO's original rate increase request. The new rates, designed to yield a return on common equity of 11.82 percent, are expected to go into effect the week of December 12, 1994. Reference is made to Form 10-K of CILCORP and CILCO for the year ended December 31, 1993, and Form 10-Q for the nine months ended September 30, 1994, under the heading CILCO Gas Rate Increase Request. As a part of its rate order, the ICC disallowed approximately $7.5 million of CILCO's investment in the Springfield cast iron renewal project. Of this amount, CILCO previously recorded a pre-tax charge of approximately $4.6 million against third quarter 1994 earnings. CILCO plans to record the remaining disallowance through a one-time, pre-tax charge of approximately $2.9 million against fourth quarter net income.
