Acquisitions of Businesses On January 4, 2017 and March 1, 2017 , we acquired two companies for a total consideration of $84.8 million .

The other company provides mobile mechanical services within the Western region of the United States, and its results have been included in our United States building services segment. In connection with these acquisitions, we acquired working capital of $9.6 million and other net assets of $0.3 million and have preliminarily ascribed $28.7 million to goodwill and $46.2 million to identifiable intangible assets. We expect that all of the acquired goodwill will be deductible for tax purposes. The purchase price allocations for the businesses acquired in 2017 are still preliminary and subject to change during their respective measurement periods. The acquisition of these businesses was accounted for by the acquisition method, and the prices paid for them have been allocated to their respective assets and liabilities, based upon the estimated fair value of their assets and liabilities at the dates of their respective acquisitions by us. On April 15, 2016 , we completed the acquisition of Ardent Services, L.L.C. and Rabalais Constructors, LLC (collectively, Ardent).

Under the terms of the transaction, we acquired 100% of Ardents equity interests for total consideration of $201.4 million . In connecti
