13. Acquisitions The Company accounts for acquisitions using the purchase method in accordance with ASC 805,  Business Combinations.  The results of operations of each acquisition have been included in the accompanying condensed consolidated financial statements as of the date of the acquisition. NEP On October 3, 2012, the Company acquired substantially all of the assets and certain obligations of Northeast Energy Partners, LLC ( NEP ) pursuant to an Asset Purchase Agreement (the  Asset Purchase Agreement ) between the Company, NEP, and its members. NEP is a Connecticut-based energy management and procurement company. The acquisition-date fair value of the consideration transferred totaled approximately $12.1 million. As part of the total consideration, NEP can earn up to $3,180,000 in contingent consideration if certain performance criteria are met post-acquisition. This potential contingent consideration consists of $2.5 million in cash and 153,153 shares of common stock and is due on December 31, 2013. The fair value of the contingent consideration was based on the weighted probability of achievement of certain revenue and earnings before interest, taxes, depreciation and amortization ( EBITDA ) levels for the 12-months ending September 30, 2013. The Company has valued this contingent payment at $2.2 million, which has been recorded within current liabilities as accrued contingent consideration. In initially measuring the fair value of the contingent consideration, the Company assigned probabilities to these performance criteria, based among other things on the nature of the performance criteria and the Company s due diligence performed at the time of the acquisition. The NEP acquisition operating results have been included within the Company s Energy procurement services segment since the date of acquisition and, therefore, discrete operating results are not maintained for its operations.
