INVENTORIES INVENTORIES
We used the last-in, first-out (LIFO) method of valuing inventories for 32 percent and 33 percent of total inventories at September 30, 2024 and June 30, 2024, respectively. Inventory valuations under the LIFO method are based on an annual determination of quantities and costs as of June 30 of each year; therefore, the interim LIFO valuations are based on our projections of expected year-end inventory levels and costs and are subject to any final year-end LIFO inventory adjustments.
