Item 1. Changes in Control of Registrant. Not applicable. Item 2. Acquisition or Disposition of Assets. On December 5, 2000, Adirondack Hydro Development Corporation ("AHDC"), an indirect subsidiary of the Registrant, acquired a 19.8% limited partnership interest in each of Northern Electric Power Company, L.P. ("Northern Electric") and South Glens Falls Limited Partnership ("South Glens Falls") from Allstate Insurance Company and Allstate Life Insurance Company (collectively referred to as "Allstate") by paying approximately $4.2 million in cash. The acquisition was funded through the Registrant's subsidiaries' revolving credit facility pursuant to a Credit Agreement dated as of June 30, 2000, as amended, between Wyodak Resources Development Corp. and Black Hills Energy Capital, Inc., as joint and several borrowers, and the financial institutions thereto, as banks, and ABN Amro Bank N.V., as administrative agent. Northern Electric owns Hudson Falls, a hydroelectric facility located on the Hudson river near the Town of Moreau, in Saratoga and Washington Counties, New York. South Glens Falls owns a hydroelectric facility located on the Hudson River in the Village of South Glens Falls, Saratoga County, New York. Prior to the closing of this transaction, there was no material relationship between Allstate and the Registrant or any of its affiliates, any director or officer of the Registrant or any of their associates except that the Registrant through its subsidiaries owned a 0.5% general partnership interest and a 9.9% limited partnership interest in each of Northern Electric and South Glens Falls. In addition, the Registrant through its subsidiaries provides management, administrative and operating services at cost to Northern Electric and South Glens Falls. The purchase price was determined through arms-length negotiations between Allstate and AHDC. In addition to the above transaction, as described below, the Registrant also acquired several related businesses throughout 2000 including Indeck Capital, Inc. ("Indeck"). The acquisition of Indeck was previously reported on the Registrant's Form 8-K dated July 7, 2000. On July 7, 2000, the Registrant completed the acquisition of Indeck by merging it into Black Hills Energy Capital, a wholly owned subsidiary of the Registrant. At the time of the acquisition, Indeck owned varying interests in 14 operating independent power plants (including Hudson Falls and South Glens Falls) in California, New York, Massachusetts, Colorado and Idaho totaling approximately 350 MWs and managed fund equity of approximately $750 million in six power-related power funds. The power funds have investments in over 35 power projects throughout the United States and various foreign countries. The Indeck acquisition was a stock transaction, and was accounted for under the purchase method of accounting. The Registrant issued approximately 1.54 million shares of common stock (approximately 7 percent of the Registrant's common stock after the transaction) and 4,000 shares of convertible preferred stock to the shareholders of Indeck for a total consideration of approximately $38 million. In addition, the Registrant assumed approximately $40million of debt.Additional consideration, consisting of common and convertible preferred stock may be paid in the form of an earn-out over a four-year period. The earn-out consideration is based on the acquired company's earnings during such four year period and cannot exceed $35 million in total. The purchase price was determined through arms-length negotiations between the Registrant and Indeck's shareholders. The shareholders of Indeck were Gerald R. Forsythe, Michelle R. Fawcett, Marsha Fournier, Monica Breslow, Melissa S. Forsythe and John W. Salyer, Jr. Prior to the closing of the Indeck transaction, there was no material relationship between Indeck's shareholders and the Registrant or any of its affiliates, any director or officer of the Registrant or any of their associates except that the Registrant through its subsidiaries and Indeck jointly owned Black Hills Colorado, LLC and both parties held interests in Indeck North American Power Partners, L.P. and Indeck North American Power Fund, L.P. Black Hills Colorado owned 111 megawatts of combustion turbine generating facilities in the Front Range of Colorado.
