Item 1.01	Entry into a Material Definitive Agreement
On September 28, 2012, Wisconsin Public Service Corporation (WPS) entered into an agreement to acquire all of the equity interests in Fox Energy Company LLC. The purchase includes the Fox Energy Center, a 593-megawatt combined-cycle electric generating facility located in Kaukauna, Wisconsin, along with associated contracts. WPS currently supplies natural gas for the facility and purchases 500 megawatts of capacity and the associated electrical output under a tolling arrangement. The tolling arrangement will be terminated immediately prior to acquisition of the facility. WPS will pay $390 million to purchase Fox Energy Company LLC, subject to post-closing adjustments, primarily related to working capital. In addition, WPS will pay $50 million to terminate the existing tolling arrangement. The transaction is expected to close on or around April 1, 2013. The agreement is subject to the approval of the lenders who currently provide project financing for the sellers. Once the agreement receives lender approval, the transaction is also subject to state regulatory approvals, including cost recovery, federal regulatory approvals, and the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
Fox Energy Company LLC is owned by Fox Energy OP, L.P., a subsidiary of GE, and Fox River Power, LLC, a subsidiary of Tyr Energy, Inc.
