Inventory

Inventories are priced at the lower of cost, determined on a first-in, first-out basis, or net realizable value. Inventories include material, labor and factory overhead required in the production of our products.

Inventory obsolescence is examined on a regular basis. When determining our estimate of obsolescence, we consider inventory that has been inactive for five years or longer and the probability of using that inventory in future production. The obsolete inventory generally consists of Learjet parts and electrical components.

Inventory is comprised of the following, net of the estimate for obsolete inventory of $532 at October 31, 2025 and $558 at April 30, 2025.
