(1) Includes measurement period adjustments related to current and prior year acquisitions. Goodwill acquired during the period was $0.4 million. No goodwill has been allocated to our Nitrogen Production or Foods segments, which consist of investments accounted for under the equity method. During the years ended August 31, 2016 and 2015, we had acquisitions which resulted in $9.8 million and $0.4 million of goodwill, respectively, for which we paid cash consideration of $11.9 million and $305.2 million, respectively. These acquisitions were primarily within our Ag segment and were not material, individually or in aggregate, to our consolidated financial statements. During the year ended August 31, 2016, we disposed of a business resulting in a reduction of $0.7 million of goodwill. There were no business disposals resulting in decreases to goodwill during fiscal 2015. Intangible assets subject to amortization primarily include customer lists, trademarks and non-compete agreements, and are amortized over their respective useful lives (ranging from 2 to 30 years).
