Adjustment to value inventory at cost on the LIFO method(317,382)(344,312)
$940,808 $769,403 
Inventories include $276.3 million and $275.5 million recorded on the FIFO method at December 31, 2023 and 2022, respectively, and $158.7 million and $201.4 million recorded on the average cost method at December 31, 2023 and 2022, respectively. During 2022, we implemented an inventory management program which resulted in permanent reductions of inventories valued under the LIFO method. This resulted in liquidations of inventory layers carried at costs prevailing in prior years and thereby decreased cost of goods sold by $83.0 million for the year ended December 31, 2022.
