Jun. 15--TXU Corp. filed documents Thursday that put a slightly higher price on the planned buyout of the Dallas-based power company and detailed the participation of the various private-equity groups, investment bankers and lenders involved in the deal

The investment group seeking to buy TXU will pay $46.7 billion for the state's biggest electric utility, compared with the previous estimate of $45 billion. Also, TXU's management expects the company's profit, a record $2.55 billion last year, to dip sl ghtly in 2007 before rising to $3.3 billion by 2011, according to TXU's filing with the Securities and Exchange Commission. Texas Energy Future Holdings L.P., as the investment group is known, intends to pay $8 billion in cash toward the purchase price, Dallas-based TXU said in its disclosure to the Securities and Exchange Commission. In addition, the buyers will assume exis ing debt and also have commitments for just over $37 billion in debt financing from lenders Citibank, JPMorgan Chase Bank, Goldman Sachs, Lehman Bros.

and Morgan Stanley. The deal, which could be the biggest buyout ever when completed, is expected to close during the year's fourth quarter, the filing says. The company has not set a date for shareholders to vote on the deal. Most of the debt used in the transaction will be secured by "substantially all of the assets" of Texas Competitive Electric Holdings, which will be the new name given to TXU's deregulated generating, retail, wholesale and trading operations. Texas Energ Future Holdings has already pledged that TXU's regulated business, Oncor Electric Delivery Co., will not incur any new debt as a result of the buyout.

TXU got a boost Wednesday when the Texas Commission on Environmental Quality approved the company's plan to build the Oak Grove coal-fired power plant southeast of Waco. The company's shares (ticker: TXU) rose Thursday about 1 percent to $67.72, approac ing the $69.25 a share buyout price. According to the SEC filing, investment-banking firm Credit Suisse valued the firm under three scenarios, based on how many coal-fired power plants TXU were to build. The scenarios were no new coal plants, five new plants or 10 new plants. At the time, XU had announced plans to build 11 coal-fired plants, a move that environmental and municipal interests criticized.

Texas Energy Future Holdings later agreed to cancel eight of the plants if it succeeds in buying TXU. Credit Suisse's initial valuations ranged from a low of $50.42 a share, assuming no new plants, and a high of $67.34, assuming five new plants. Another valuation using different natural gas prices produced values ranging from $52.99 to $70.99. Yet anoth r valuation, this one by investment banker Lazard Frères, valued the company's shares at between $56.32 and $67.78. TXU management projected that the company would earn a net profit of $2.3 billion in 2007, rising steadily to $3.3 billion in 2011.
