Acquisitions	4. Acquisitions On April 1, 2017, we acquired all of the issued and outstanding stock of BCH Holdings, Inc. and each of its wholly-owned subsidiaries (collectively “BCH”) for $121.3 million of which $97.0 million was allocated to goodwill and identifiable intangible assets. The total purchase price included $95.4 million in cash, $14.3 million in notes payable to former owners and an $11.6 million contingent earn-out obligation. BCH is an integrated, single-source provider of mechanical service, maintenance and construction with headquarters in Tampa, Florida and operations throughout the southeastern region of the United States, which reports as a separate operating location. We completed three acquisitions in the second quarter of 2018 and two acquisitions in the first quarter of 2018 with a total purchase price of $18.1 million for the six months ended June 30, 2018. In addition to the BCH acquisition, we completed four additional acquisitions in 2017. The total purchase price for these additional acquisitions, including earn-outs, was $9.4 million. These acquisitions were not material and were “tucked-in” with existing operations. The results of operations of acquisitions are included in our consolidated financial statements from their respective acquisition dates. Our consolidated balance sheet includes preliminary allocations of the purchase price to the assets acquired and liabilities assumed for the applicable acquisition pending the completion of the final valuation of intangible assets and accrued liabilities. The acquisitions completed in the current and prior year were not material, individually or in the aggregate. 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.
