Inventories are valued at the lower of cost or net realizable value. The net realizable value of inventories were below recorded costs by approximately $0.1 million as of June 30, 2017 without similar adjustments required as of December 31, 2016; therefore we reduced the value of inventory in our Condensed Consolidated Financial Statements for this difference in 2017.
