Item 2.01	Entry into a Material Definitive Agreement
On March 28, 2013, Wisconsin Public Service Corporation (WPS) acquired all of the equity interests in Fox Energy Company LLC from Fox Energy OP, L.P., a subsidiary of GE, and Fox River Power, LLC, a subsidiary of Tyr Energy, Inc. The purchase included the Fox Energy Center, a 593-megawatt combined-cycle electric generating facility located in Kaukauna, Wisconsin, and associated contracts. WPS paid $391.6 million to purchase Fox Energy Company LLC, subject to post-closing working capital adjustments. Prior to the purchase, WPS supplied natural gas for the facility and purchased 500 megawatts of capacity and the associated energy output under a tolling agreement. WPS paid $50.0 million for the early termination of the tolling agreement. The purchase was financed with a combination of short-term debt and cash flow from operations. The short-term debt will be replaced later in 2013 with long-term financing.
