The Company performs a lower of cost or net realizable value analysis on inventory to determine if the net realizable values of certain inventories are less than their carrying value, which is attributable primarily to decreases in market prices of corn and ethanol. Based on the lower of cost or net realizable value analysis, as a component of cost of goods sold, the Company recorded a loss on ethanol inventories of approximately $949,000 and $1,488,000 for the three months ended April 30, 2020 and 2019, respectively, and approximately $2,151,000 and $765,000 for the six months ended April 30, 2020 and 2019, respectively. Based on the lower of cost or net realizable value analysis, as a component of cost of goods sold, the Company recorded a loss on corn inventories of approximately $1,087,000 and $71,000 for the three months ended April 30, 2020 and 2019, respectively, and approximately $1,213,000 and $95,000 for the six months ended April 30, 2020 and 2019, respectively.
