In December 2006, we reached an agreement to sell our natural-gas fired merchant generation facility, Armstrong.
The sale is expected to close in the first quarter of 2007. As a result of this pending sale, the results of operations for this facility will no longer be included in our results from continuing operations. Our ratios of earnings to fixed charges
for prior years have been recast to conform to this presentation. On February 27, 2007, an affiliate acquired from Armstrong, a majority equity interest in exchange for a reduction in net amounts owed to the affiliate of approximately $207 million.
Immediately following this transaction, we sold our remaining minority interest in Armstrong to the affiliate.
