In April of 2015, FutureFuel acquired additional historical line space on a pipeline for $1,408. The acquired line space was recorded as an intangible asset with an indefinite life as there was no foreseeable limit on the time period over which it is expected to contribute to cash flows. The carrying value of the asset was $1,408 and $0, respectively, as of December 30, 2015 and 2014. The Company tested the intangible asset for impairment in accordance with codification ASC 350-30-35-18 through 35-20 and no impairment was necessary for either period.
