(1) This schedule presents on a proforma basis, the results of operations of
AES excluding the aggregate (both subsidiaries and affiliates) South American
affiliates foreign currency losses of approximately $114 million after income
tax and mark to market gain from FAS No. 133 of approximately $35 million
after income tax. This schedule also excludes loss on discontinued operations
of $215 million consisting mainly of Termocandelaria, Ib Valley, Power Direct
and telecommunication businesses in Brazil, the United States and the AES
Fifoots Point generation facility in the United Kingdom. In addition,
effective January 1, 2002, AES adopted the 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. SFAS No. 142 adopts a fair value model for evaluating impairment of
goodwill in place of the recoverability model used previously. AES wrote-off
the goodwill associated with certain acquisitions where the current fair
market value of such businesses is less than the current carrying value of
the business, primarily as a result of reductions in fair value associated
with lower than expected growth in electricity consumption compared to the
original estimates made at the date of acquisition. If the excluded items are
taken into account, certain CILCO/CILCORP contributions to AES/CILCORP on a
consolidated basis would be different as follows: (6.62%) CILCO to Net Income
and (16.56%) CILCORP to Net Income.
