Item 1.01 Entry into a Material Definitive Agreement

 

On May 24, 2006, the Registrant (the “Guarantor”) entered into an Amended and Restated Guaranty dated as of May 24, 2006, in favor of Wygen Funding, Limited Partnership (“Lessor”).

Under the terms of the original Guarantee, the Registrant guaranteed the obligations of the Registrant’s subsidiary, Black Hills Wyoming, Inc. (the “Lessee”), pursuant to the Lease Agreement for the Wygen I plant with Wygen Funding (the “Lessor”) dated as of July 20, 2001, which was filed as Exhibit 10.33 to the Registrant’s Form 10-K for 2001, and is incorporated herein by reference. Wygen Funding is considered a variable interest entity and the Lessee is considered the primary beneficiary, therefore the variable interest entity has been consolidated by the Registrant in its consolidated financial statements since 2003. Approximately $128 million of Lessor debt is currently included in the Registrant’s consolidated balance sheet, which is comprised of $111.1 million of Tranche A debt due June 30, 2006 and $17.2 million of Tranche B debt due June 30, 2008. The maturity of the Tranche A debt has been extended from June 30, 2006 to June 30, 2008.

The Amended and Restated Guarantee amends the financial covenants to conform them to the financial covenants in the Registrant’s existing revolving credit facility and to include the extension of Tranche A debt under the guarantee.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

 

The information required by this item is included in Item 1.01.
