Mirant Writes Off Chile's Edelnor, Seeks Buyer

LCG, Oct. 22, 2001--Mirant Corp. of the United States said on Friday it would write off its entire investment in Chilean power company Empresa Electrica del Norte Grande S.A. (Edelnor), and would seek a buyer for the money-losing company.

The announcement came following decisions by Electroandina, a Chilean utility, and AES Corp. of the U.S. to cancel their bids to acquire control of Edelnor by buying the Chilean company's debt for about a two-thirds discount.

Mirant has said for some time that it would not invest any new money in Edelnor and confirmed Friday that liquidity was a major problem for its Chilean unit.

Mirant also said it could give no assurance that Edelnor would be able to make interest payments due on December 15.
