(1) This schedule presents, on a proforma basis, the results of operations of
AES excluding the following items: (1) Mark to market effect of FAS No. 133.
(For the 12-month period ending September 30, 2002, the net mark to market
gain from FAS No. 133 was $83 million.); (2) Loss on sale or write-down of
investments. (In the second quarter of 2002, AES recorded an impairment
charge of $40 million on an equity method of investment in a
telecommunications company in Latin America, and a loss on the sale of an
equity method investment in a telecommunications company in Latin America of
approximately $14 million. In the first quarter of 2002, a subsidiary of AES
sold an available-for-sale security resulting in gross proceeds of $92
million. The realized loss on the sale was $50 million. Approximately $48
million of the loss related to recognition of previously unrealized losses
which had been recorded in other comprehensive income.); (3) Foreign currency
transaction losses. (Foreign currency transaction losses due to devaluation
in Brazilian Real and devaluation in the Argentina Peso offset by foreign
transaction gains in Venezuelan Bolivar. The net foreign currency transaction
loss is approximately $284 million.); (4) Discontinued operations. (The
schedule excludes net loss of discontinued operations of $513 million
consisting mainly of Termocandelaria, IB Valley, Power Direct,
telecommunications businesses in Brazil and US, Fifoots, Eletronet, Cilcorp,
NewEnergy and Medina Valley.); (5) Accounting change. (In April 2002, AES
adopted Derivative Implementation Group (DIG) Issue C-15 which established
specific guidelines for certain contracts to be considered normal purchases
and normal sales contracts. This resulted in a cumulative effect of an
accounting change increase to $127 million, net of income tax effects. On
January 1, 2002, AES adopted SFAS No. 142, "Goodwill and Other Intangible
Assets" which establishes accounting and reporting standards for goodwill and
other intangible assets. The adoption of SFAS No. 142 resulted in a
cumulative reduction to income of $473 million, net of income tax effects.);
(6) Provision for regulatory decision in Brazil. (AES has recorded the
retroactive regulatory decision by the Brazilian regulator depriving AES Sul
of amounts the company believes it was entitled to receive as a reduction in
revenue.) If the excluded amounts are taken into account, certain
CILCO/CILCORP contributions to AES/CILCORP on a consolidated basis would be
different as follows: (5.01%) CILCO to Net Income and (6.44%) CILCORP to Net
Income.

(2) For purposes of comparison with the prior period, the CILCORP and CILCO data
for gross revenues, net operating revenues and operating income were added to
AES consolidated data to arrive at AES/CILCORP amounts.
