Acquisitions	ACQUISITIONS 2016 Acquisitions Effective December 1, 2015, we acquired all of the outstanding stock of Westway Services Holdings (2014) Ltd. (“Westway”), a provider of technical engineering services to customers in the United Kingdom, for a purchase price of $81.0 million. We accounted for this acquisition under the acquisition method of accounting. Accordingly, we allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values, and recorded the excess of the purchase price as goodwill. As of April 30, 2016, the valuation of the intangible assets was incomplete. As such, the purchase price allocation reflects preliminary amounts of net assets acquired, including other intangible assets. These net assets are subject to adjustments within the measurement period, which is not to exceed one year from the acquisition date. We recorded preliminary goodwill of $45.1 million, which is primarily attributable to projected long-term margin improvement through expansion of our technical services business to new and existing clients in the United Kingdom. Goodwill also reflects our identification of buyer-specific synergies that we anticipate will be realized by the reduction of duplicative positions, back office functions, professional fees, and other services.
