2. | BUSINESS COMBINATIONS
During the six months ended October 31, 2014, we acquired one solid waste hauling operation in each of the Eastern and Western regions, whereas, during the six months ended October 31, 2013, we acquired three solid waste hauling operations, two of which are located in the Western region and one of which is located in the Eastern region, and an industrial service management business (included in the Other segment). The operating results of these businesses are included in the accompanying 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. Intangible assets other than goodwill that are subject to amortization include acquired client lists and non-compete agreements, which are often negotiated as a part of our business combinations. These are amortized over a five to ten year period from the date of acquisition. Amounts recorded to goodwill are in most cases expected to be deductible for tax purposes. The purchase price paid for these acquisitions during the six months ended October 31, 2014 and 2013 and the allocation of the purchase price is as follows:
