In September 2014, the Company acquired Rumsey Environmental, LLC (“Rumsey”), which provides solid waste collection services in western Alabama, for aggregate total cash consideration of $16,000 and contingent consideration of $1,891. Contingent consideration represents the fair value of up to $2,000 of amounts payable to the former owners based on the achievement of certain operating targets specified in the asset purchase agreement. The fair value of the contingent consideration was determined using probability assessments of the expected future cash flows over the two-year period in which the obligation is expected to be settled, and applying a discount rate of 2.8%. The Company also acquired three individually immaterial non-hazardous solid waste collection, transfer and disposal businesses during the nine months ended September 30, 2014. The Company acquired six individually immaterial non-hazardous solid waste collection businesses during the nine months ended September 30, 2013. Cash consideration for the acquisition of the business of R360 Environmental Solutions, Inc. (“R360”) in October 2012 included payment for the estimated net working capital of $18,906, as defined in the acquisition agreement, which was subject to final adjustment subsequent to the close of the acquisition. In March 2013, Waste Connections received $18,000 from the former owners of R360 due to the final adjustment to the net working capital that was estimated at the closing date. During the nine months ended September 30, 2014 and 2013, the Company incurred $1,384 and $974, respectively, of acquisition-related costs. These expenses are included in Selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Net Income.
