Inventory Disclosure [Abstract] |
Inventories | Inventories Inventories at September 30 consist of:
| 2021 |  | 2020
Raw materials and supplies | $ | 4,111 |  |  | $ | 6,548 |
Work-in-process | 3,560 |  |  | 3,786 |
Finished goods | 4,875 |  |  | 5,235 |
Total inventories | $ | 12,546 |  |  | $ | 15,569 |
If the FIFO method had been used for the entire Company, inventories would have been $9,210 and $8,286 higher than reported at September 30, 2021 and 2020, respectively. LIFO expense was $924 in fiscal 2021 and a LIFO benefit was $10 in fiscal 2020. In fiscal 2021, 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 approximately $156 during fiscal 2021. 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.
