Acquisitions	4. Acquisitions We completed two acquisitions in the first quarter of 2016. We acquired the remaining 40% noncontrolling interest in Environmental Air Systems, LLC (“EAS”) on January 1, 2016 for $46.6 million, including $42.0 million funded on the closing date plus a holdback, an earn-out that we will pay if certain financial targets are met after the acquisition date and a working capital adjustment. Due to our majority ownership and control over EAS on the acquisition date, the difference between the purchase price and the noncontrolling interest liability was recorded in Additional Paid-In Capital in our Balance Sheet. Additionally in the first quarter of 2016, we acquired 100% of the ShoffnerKalthoff family of companies (collectively, “Shoffner”), which reports as a separate operating location in the Knoxville, Tennessee area. Shoffner was included in our consolidated results of operations beginning on its acquisition date, which included revenue of $71.9 million. The acquisition date fair value of consideration transferred for this acquisition was $19.8 million, of which $14.8 million was allocated to goodwill and identifiable intangible assets. The purchase price included $15.5 million funded on the closing date plus a note payable to former owners, an earn-out that we will pay if certain financial targets are met after the acquisition date and a working capital adjustment. The acquisitions completed in the current year were not material, individually or in the aggregate. Other Acquisitions We completed various other acquisitions in 2016 and 2015 which were not material, individually or in the aggregate, and were “tucked-in” with existing operations. The total purchase price for the “tucked-in” acquisitions, including earn-outs, was $0.1 million in 2016 and $8.3 million in 2015. The results of operations of acquisitions are included in our consolidated financial statements from their respective acquisition dates. Additional contingent purchase price (“earn-out”) has been or will be paid if certain acquisitions achieve predetermined profitability targets. Such earn-outs are not subject to the continued employment of the sellers.
