Alliant Energy also affirms 2007 earnings guidance MADISON, Wis., Dec. 20 /PRNewswire-FirstCall/ -- Alliant Energy Corporation (NYSE: LNT) announced today that its board of directors has approved an increase in its 2008 expected annual common stock dividend to $1.40 per share from the current annual dividend of $1.27 per share. Payment of the 2008 quarterly dividends will be subject to the actual dividend declaration by the board of directors, which is expected in January for the initial quarterly dividend. The increase is consistent with the Company's previously announced desire to achieve a targeted dividend payout ratio of 60 to 70 percent of the earnings of its utility subsidiaries. (Logo: http://www.newscom.com/cgi-bin/prnh/20020405/LNTLOGO) "The Board is pleased to announce this increase," said William D. Harvey, Alliant Energy's Chairman, President and CEO. "It is quite satisfying to raise the dividend by more than 10% while remaining committed to meeting the ongoing capital requirements of the company and growing our earnings."
