Item 2.02Results of Operations and Financial Condition.

On October 30, 2009, Alliant Energy Corporation (“Alliant Energy”) issued a press release announcing its earnings for the third quarter ended September 30, 2009. A copy of such press release is furnished as Exhibit 99.1 and is incorporated by reference herein.

Alliant Energy included in the press release third quarter 2009 income from continuing operations and earnings per share from continuing operations excluding a one-time non-cash charge related to Alliant Energy’s tender offer for its Exchangeable Senior Notes due 2030 (Notes) and utility, non-regulated and parent earnings (losses) per share from continuing operations, which are non-GAAP (accounting principles generally accepted in the United States of America) financial measures.  Alliant Energy believes income from continuing operations and earnings per share from continuing operations excluding the charge related to the tender offer for the Notes is useful to investors because it provides an alternate measure to better understand and compare across periods the operating performance of Alliant Energy without the distortion of a non-cash charge that Alliant Energy does not expect to recur in future periods and to provide additional information about Alliant Energy’s operations on a basis consistent with the measures that management uses to manage its operations and evaluate its performance.  Alliant Energy believes utility, non-regulated and parent earnings (losses) per share from continuing operations are useful to investors because they facilitate an understanding of segment performance and trends and provide additional information about Alliant Energy’s operations on a basis consistent with the measures that management uses to manage its operations and evaluate its performance.  Alliant Energy’s management also uses utility earnings per share from continuing operations to determine incentive compensation.
