Note 4. Research, Development and Engineering

Garrett conducts research, development, and engineering (“RD&E”) activities, which consist primarily of the development of new products and product applications. RD&E costs are included in Cost of goods sold. Customer reimbursements are netted against gross RD&E expenditures as they are considered a recovery of cost. RD&E costs are charged to expense as incurred unless the Company has a contractual guarantee of reimbursement from the customer, in which case the related costs are capitalized. Total RD&E expenses, net of customer reimbursements, amounted to the following:
