Raw materials and supplies$1,416 $1,044 
Work-in-process1,325 3,419 
Finished goods1,451 1,767 
Total inventories$4,192 $6,230 
If the FIFO method had been used for the entire Company, inventories would have been $10,897 and $10,496 higher than reported at September 30, 2025 and 2024, respectively. LIFO expense was $401 and $862 in fiscal 2025and 2024, respectively.
Results showed a reduction of inventory resulting in liquidations of LIFO inventory quantities in fiscal 2024. The estimated liquidation of LIFO inventory quantities results in a projected increase in cost of goods sold of nil and $610 during fiscal 2025 and 2024, 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 within cost of goods sold line within the Statements of Operations in amount of $992 and $1,412 for the years ended September 30, 2025 and 2024, respectively.
