The main headline of an article about Constellation Energy Group Inc. in Saturday's editions could have led readers to believe the company was considering the sale of the bulk of Baltimore Gas and Electric Co. The company might consider the sale only of its transmission lines, which represent just a small portion of the utility's business. In addition, the article incorrectly reported the company's forecast for second-quarter earnings per share. The correct forecast is for second-quarter earnings of 50 to 55 cents per share. The Sun regrets the error.
