Business Combinations [Abstract]
Acquisitions Of Businesses	Acquisitions of Businesses Acquisitions are accounted for utilizing the acquisition method of accounting and the prices paid for them are allocated to their respective assets and liabilities based upon the estimated fair value of such assets and liabilities at the dates of their respective acquisition by us. During the first nine months of 2023, we acquired seven companies for total consideration of $92.8 million. Such acquisitions include: (a) a national energy efficiency specialty services firm, the results of operations of which have been included in our United States building services segment, and (b) six companies that enhance our presence in geographies where we have existing operations, the results of operations of which were de minimis, consisting of: (i) two companies that have been included within our Unites States mechanical construction and facilities services segment, one of which provides mechanical and pipe fabrication services, and one of which provides fire protection services, both in the Midwestern region of the United States, and (ii) four mechanical services companies in the Western and Midwestern regions of the United States, that have been included within our United States building services segment. In connection with these acquisitions, we acquired working capital of $9.1 million and other net liabilities of $6.7 million, including certain deferred tax liabilities, and have preliminarily ascribed $34.2 million to goodwill and $56.2 million to identifiable intangible assets. We expect that $23.2 million of the goodwill and identifiable intangible assets acquired in connection with these 2023 acquisitions will be deductible for tax purposes. During calendar year 2022, we acquired six companies for total consideration of $100.8 million. Such acquisitions include: (a) a company that provides electrical construction services in the Greater Boston area, the results of operations of which have been included in our United States electrical construction and facilities services segment, and (b) five companies that enhance our presence in geographies where we have existing operations, the results of operations of which were de minimis, consisting of: (i) two companies that provide fire protection services in the Northeastern and Southern regions of the United States, respectively, and that have been included within our United States mechanical construction and facilities services segment, (ii) two companies that specialize in either building automation and controls or mechanical services in the Southwestern and Southern regions of the United States, respectively, and that have been included within our United States building services segment, and (iii) a company that provides electrical construction services in the Midwestern region of the United States and that has been included within our United States electrical construction and facilities services segment. In connection with these acquisitions, we acquired working capital of $7.1 million and other net liabilities of $1.1 million, and have ascribed $28.9 million to goodwill and $65.9 million to identifiable intangible assets. We expect that all of the goodwill and identifiable intangible assets acquired in connection with these 2022 acquisitions will be deductible for tax purposes. The purchase price allocations for the businesses acquired in 2023 are preliminary and subject to change during their respective measurement periods. As we finalize such purchase price allocations, adjustments may be recorded relating to finalization of intangible asset valuations, tax matters, or other items. Although not expected to be significant, such adjustments may result in changes in the valuation of assets and liabilities acquired. The purchase price allocations for the businesses acquired in 2022 have been finalized during their respective measurement periods with an insignificant impact.
