(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 June 30, 2002, the net mark to market gain from FAS
No. 133 was $53 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 $184 million.); (4) Discontinued operations.
(The schedule excludes net loss of discontinued operations of $300 million
consisting mainly of Termocandelaria, IB Valley, Power Direct,
telecommunications businesses in Brazil and US, Fifoots, Eletronet, Cilcorp and
NewEnergy.); (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: (2.89%) CILCO to Net Income and (7.61%) 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.
