Warren Buffett Continues to Cut Constellation Energy Stake
Warren Buffett's Berkshire Hathaway is still chipping away at the almost 20 million shares of Constellation Energy it received last December as part of its break-up fee.

Berkshire's MidAmerican Energy Holdings had made a deal a few months before, at the height of the credit crisis, to buy Constellation. Constellation decided to go with France's ECF instead. It handed over the 20 million shares for changing its mind.

As of mid-February, Berkshire had sold over five million CEG shares for a total of $137 million. That brought its Constellation stake down to 14.8 million shares.

Today, an SEC filing lists another series of sales that brings Berkshire's stake down by 2.3 million shares to 12,476,154. That's 6.26 percent of Constellation shares outstanding, down from 7.45 percent in mid-February and 10 percent at the end of last year.

Here's a listing of the sales detailed in the latest filing:
