Item 2.02 Results of Operations and Financial Condition.
On August 3, 2012, Alliant Energy Corporation (“Alliant Energy”) issued a press release announcing its earnings for the second quarter ended June 30, 2012. 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 income from continuing operations and earnings per share from continuing operations for the second quarter ended June 30, 2012 excluding regulatory-related credits from Wisconsin Power and Light Company rate case decision in June 2012. Alliant Energy included in the press release income from continuing operations and earnings per share from continuing operations for the second quarter ended June 30, 2011 excluding tax benefits from Wisconsin tax legislation, net regulatory-related charges and credits from Interstate Power and Light Company electric rate case decisions in June 2011, a charge related to Alliant Energy's Cash Balance Pension Plan, and regulatory asset impairments. Alliant Energy believes these non-GAAP financial measures (financial measures not prepared in accordance with accounting principles generally accepted in the United States of America) are useful to investors because they provide an alternate measure to better understand and compare across periods the operating performance of Alliant Energy without the distortion of items that management believes are not normally associated with ongoing operations, and also 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 income from continuing operations, as adjusted, to determine incentive compensation.
In addition, Alliant Energy included in the press release Interstate Power and Light Company, Wisconsin Power and Light Company, Alliant Energy Corporate Services, Inc., utility and Alliant Energy Corporate Services, Inc., and non-regulated and parent earnings per share from continuing operations for the second quarter ended June 30, 2012 and 2011. Alliant Energy believes these non-GAAP financial measures 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 and Alliant Energy Corporate Services, Inc. earnings per share from continuing operations to determine incentive compensation.
