The following table presents the fair value hierarchy, pre-impairment value, inventory impairment charges and fair value for our assets measured on a nonrecurring basis for the nine months ended August 31, 2019 and the year ended November 30, 2018 (in thousands): 

		August 31, 2019							November 30, 2018
