        On October 1, 2009, the Company sold all significant assets of Applied Utility Systems, Inc., which comprised the Company’s Energy Systems division, for up to $10.0 million, including $8.6 million in cash and contingent consideration of $1.4 million. Of the contingent consideration, $0.5 million was contingent upon Applied Utility Systems being awarded certain projects and $0.9 million is retention against certain project and contract warranties and other obligations. The Company has not recognized any of the contingent consideration as of December 31, 2012 and will only do so if the contingencies are resolved favorably. The $0.5 million of contingent consideration that was contingent on the award of certain projects was not earned and will not be paid.

The Company continues to incur legal and other expenses related to this discontinued operation.
