Inventories

Inventories are valued at the lower of cost and net realizable value. Cost is principally determined using the first-in, first-out method. Our gross used truck inventory was $253 million at January 31, 2020 compared to $200 million at October 31, 2019, offset by reserves of $53 million and $37 million, respectively.
