INVESTMENT IN ATC

Our wholly-owned subsidiary, Rainy River Energy, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains electric transmission assets in parts of Wisconsin, Michigan, Minnesota and Illinois. ATC rates are FERC-approved and are based on a 12.2 percent return on common equity dedicated to utility plant. We account for our investment in ATC under the equity method of accounting. As of March 31, 2013, our equity investment in ATC was $109.0 million ($107.3 million at December 31, 2012). In the first quarter of 2013, we invested $0.4 million in ATC, and on April 29, 2013, we invested an additional $1.2 million. We expect to make additional investments of approximately $1.5 million in 2013.
