Inventories at September 30 consist of:
20242023
Raw materials and supplies$1,044 $944 
Work-in-process3,419 1,977 
Finished goods1,767 1,626 
Total inventories$6,230 $4,547 
If the FIFO method had been used for the entire Company, inventories would have been $10,496 and $9,634 higher than reported at September 30, 2024 and 2023, respectively. LIFO expense was $862 in fiscal 2024 and benefit of $305 in fiscal 2023.
Results showed a reduction of inventory resulting in liquidations of LIFO inventory quantities. The estimated liquidation of LIFO inventory quantities results in a projected increase in cost of goods sold of $610 and $1,476 during fiscal 2024 and 2023, respectively. These inventories were carried in prior periods at the then prevailing costs, which were accurate at the time, but differ from the current manufacturing cost and/or material costs.
The allocation of production costs to inventory are based on a normal range of capacity in production. The amount of cost allocated to each unit of production is not increased as a consequence of low production or idle capacity. As a result, the Company recorded idle cost of $1,412 and $2,149 for the years ended September 30, 2024 and 2023, respectively.
