At December 31, 2014, restricted cash of $31.3 million was recorded within other long-term assets on our balance sheet. This amount was held in the rabbi trust and was a portion of the required funding for the rabbit trust that was triggered by the announcement of the proposed merger with Wisconsin Energy Corporation. See Note 2, Proposed Merger with Wisconsin Energy Corporation, for more information about the proposed merger. See Note 18, Employee Benefit Plans, for more information on the rabbi trust funding requirements.
