BUSINESS COMBINATIONS

We acquired one solid waste collection, transfer and processing business in our Eastern region, Complete Disposal Company, Inc. and its subsidiary United Material Management of Holyoke, Inc. (collectively, "Complete"), which provides residential and roll-off collection services, operates a construction and demolition processing facility, and operates a solid waste transfer station with both truck and rail transfer capabilities during the three months ended March 31, 2018. We also acquired one solid waste collection business in our Western region during the three months ended March 31, 2018. In the three months ended March 31, 2017, we acquired one solid waste collection business in our Western region. The operating results of these businesses are included in the accompanying unaudited consolidated statements of operations from each date of acquisition, and the purchase price has been allocated to the net assets acquired based on fair values at each date of acquisition, with the residual amounts recorded as goodwill. Acquired intangible assets other than goodwill that are subject to amortization include client lists and non-compete covenants. Such assets are amortized over a five to ten year period from the date of acquisition. All amounts recorded to goodwill, except amounts related to the Complete acquisition, are expected to be deductible for tax purposes.
