Southern Company confirms April 2 spin-off date for Mirant

Southern Company (NYSE:SO) announced today that it has received a favorable supplemental ruling from the Internal Revenue Service regarding its tax-free spin-off of Mirant Corporation (NYSE:MIR).

The company stated previously that the tax-free spin-off was contingent upon receipt of this ruling. Now, all necessary conditions for the spin-off have been met.

A total of 272 million shares, or 80.3 percent of Mirant, will be distributed on April 2, 2001, to Southern Company shareholders of record as of 5 PM EST on March 21, 2001.

Based on the number of shares of Southern Company common stock that are expected to be outstanding as of the record date, each shareholder will receive slightly less than .4 of a share of Mirant for every share of Southern Company common stock they own. The actual distribution ratio will be determined on the record date by dividing the number of Mirant shares to be distributed by the number of shares of Southern Company common stock outstanding.

Southern Company shareholders as of the record date will receive whole shares of Mirant and cash payments for fractional shares. The cash payments will be taxable. Shareholders will also receive a statement containing information about the spin-off.

Mirant owns more than 20,000 megawatts of electric generating capacity around the world, including about 14,000 megawatts in the United States with another 9,000 megawatts under advanced development.

Southern Company subsidiaries serve more than 3.8 million retail customers and millions more through the wholesale market.
