Mirant Corporation Files for Bankruptcy Protection

LCG, July 15, 2003Facing an $1.1 billion payment, Mirant Corp. filed for bankruptcy protection late yesterday.

The Atlanta-based company filed its petition in U.S. Bankruptcy Court in Fort Worth, Texas, and has roughly $20.6 billion in assets and $11.4 billion in debt. The company said it had $1.17 billion in cash as of July 11 and has acquired a commitment for $500 million in debtor-in-possession financing.

According to Marce Fuller, Mirant president and chief executive officer, slow market conditions and a failure to obtain the timely support of [Mirants] key lenders, contributed to the decision to seek protection. The company lost $2.4 billion last year, and auditors found $188 million in overstated income. Allegations of market manipulation have also hurt the company.

Mirant is canceling its offer to exchange 2.5 percent convertible debentures due 2021 and its 7.4 percent senior notes due 2004, and Mirant Americas Generation LLC is terminating its offer to exchange 7.625 percent senior notes due 2006.

Mirant owns power generation and natural gas assets, as well as energy risk management and marketing capabilities.
