*The  ratios  of earnings  to fixed  charges  are influenced  by the  accrual of
 interest  expense  relating  to  supplier  refunds  payable  to  customers  and
 regulatory  accounts. Ratios which exclude interest related to supplier refunds
 and regulatory accounts are calculated  as shown in the preceding  computation,
 but  exclude from  fixed charges related  interest expense  during the relevant
 period to the extent of related interest income.
