Employees shall use AUI property, facilities, equipment and services only for official and authorized purposes. These restrictions apply whether the items are owned, loaned or provided to AUI in some other manner. The use of property, facilities, equipment or services by any person, subcontractor, vendor or client for commercial purposes or for personal financial gain is strictly prohibited. In general, employees may not use AUI facilities or services to order and pay for items for their personal use. In instances where personal expenses are inadvertently, or unavoidably, charged to an AUI account (e.g., by an employee on an AUI business trip) the employee shall reimburse AUI promptly.
