Inventories are valued at the lower of cost or net realizable value. The net realizable value of inventories were not recorded below cost as of December 31, 2019 and were recorded below cost by $1.0 million as of December 31, 2018; therefore we reduced the value of inventory in our Consolidated Financial Statements for this difference in 2018.

Materials and supplies include chemicals, maintenance supplies, and spare parts which will be consumed in the mining of trona ore and production of soda ash processes.
