Inventory Disclosure [Abstract] |
Inventories |
8 | Inventories
Inventories are valued at the lower of cost or net realizable value, with cost determined by the first-in, first-out ("FIFO") method for a majority of the company's inventories and the last-in, first-out ("LIFO") and average cost methods for all other inventories. The company establishes a reserve for excess, slow-moving, and obsolete inventory that is equal to the difference between the cost and estimated net realizable value for that inventory. These reserves are based on a review and comparison of current inventory levels to planned production, as well as planned and historical sales of the inventory. Inventories were as follows:
(Dollars in thousands) |  | January 31, 2020 |  | February 1, 2019 |  | October 31, 2019
Raw materials and work in process |  | $ | 188,235 |  |  | $ | 124,458 |  |  | $ | 179,967 |
Finished goods and service parts |  | 632,796 |  |  | 364,393 |  |  | 553,767 |
Total FIFO value |  | 821,031 |  |  | 488,851 |  |  | 733,734 |
Less: adjustment to LIFO value |  | 82,071 |  |  | 72,201 |  |  | 82,071 |
Total inventories, net |  | $ | 738,960 |  |  | $ | 416,650 |  |  | $ | 651,663 |
