Inventories

5. Inventories

Inventories are valued at the lower of cost or market for last-in, first-out (“LIFO”) inventory and lower of cost or net realizable value for first-in, first-out (“FIFO”) inventory. Approximately 40 percent of inventories are valued using the LIFO method of determining cost. All other inventories are valued using the FIFO method of determining cost. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on inventory levels and costs at that time. Accordingly, interim LIFO calculations must be based on management’s estimates of expected year-end inventory levels and costs. Because these calculations are subject to many factors beyond management’s control, annual results may differ from interim results as they are subject to the final year-end LIFO inventory valuation. No adjustment to the LIFO reserve was recorded for the quarters ended June 30, 2022 or 2021.
