RESPONSE: The Accounts Receivable Sale program is a cost effective approach of funding the cost of carrying customer receivables on the Company s balance sheet. The alternative to factoring accounts receivable would be a working capital addition to rate base at the Company authorized rate of return. The Idaho authorized ROR is culTently 8.98% and the Company requested ROR is 9.82%. Program fees were approximately 1.8% during the 2002 test year on an average balance of approximately $61 million. The difference between the Company requested ROR of 9.82% and the NR Sale program fees would have been approximately 050,000 during the test year. The current treatment of fees as customer accounting related costs has been in place since 1988.
