This combined Form 8-K is separately filed by Alliant Energy Corporation, Interstate Power and Light Company and Wisconsin Power and Light Company. ITEM 4. CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT. On June 12, 2002, the Board of Directors of each of Alliant Energy Corporation, Interstate Power and Light Company and Wisconsin Power and Light Company (collectively, the "Companies"), upon the recommendation of their respective Audit Committees, dismissed Arthur Andersen LLP ("Andersen") as each of the Companies' independent accountants and engaged Deloitte & Touche LLP to serve as each of the Companies' independent accountants for 2002. Deloitte & Touche LLP will audit the financial statements of each of the Companies for the year ending December 31, 2002. Deloitte & Touche LLP will also audit the financial statements of the Alliant Energy Corporation 401(k) Savings Plan for the years ending December 31, 2001 and 2002. Andersen's reports on each of the Companies' consolidated financial statements for the years ended December 31, 2001 and 2000 did not contain an adverse opinion, disclaimer of opinion or qualification or modification as to uncertainty, audit scope or accounting principles. During the years ended December 31, 2001 and 2000 and the subsequent interim period, there were no disagreements between any of the Companies and Andersen on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of said former accountant, would have caused it to make a reference to the subject matter of such disagreements in connection with its reports ("Disagreements"). During the fiscal years ended December 31, 2001 and 2000 and the subsequent interim period, there were no reportable events (as described in Item 304(a)(1)(v) of Regulation S-K). Each of the Companies provided Andersen with a copy of the foregoing statements. Attached as Exhibits 16.1, 16.2 and 16.3 are copies of Andersen's letters, each dated June 12, 2002, regarding each of the Companies, stating its agreement with such statements. During each of the Companies' two most recent fiscal years and the subsequent interim period, none of the Companies consulted Deloitte & Touche LLP regarding the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on any of the Companies' consolidated financial statements, or any matter that was either the subject of a Disagreement or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
