The Company’s raw materials balance represents the majority of the inventory as the Company orders parts in quantity to fill orders. Work in process and finished products typically represent smaller portions of inventory as the Company does not historically hold finished products with the exception of assets transitioning to the lease fleet. The Company typically ships finished products as they are completed.
