15. Sale of Energy Systems Division

        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, 2013 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 (loss) income, net of tax of the Energy Systems division is presented as discontinued operations. The Company continues to incur legal and other expenses related to this discontinued operation. Expenses for the year ended December 31, 2013 also include amounts related to an indemnification claim for matters relating to various customer contracts that sold (see Note 17). In addition, the Company recorded a gain of $0.3 million in the year ended December 31, 2012 related to recovery of awards from Benz Air litigation. There was no revenue included within discontinued operations for the years ended December 31, 2013 or 2012.
