The Metropolitan Washington Airports Authority (Authority) LDBE Program provides opportunities to local small business firms without regard to race or sex. These LDBE firms are eligible for any Authority contract that requires LDBE participation. An LDBE is defined as a small business concern which is organized for profit and located within a 100-mile radius of Washington, DC's Zero Mile Marker. Those business entities located within cities and counties that fall partially within the aforementioned boundary are also eligible to participate in the Authority's LDBE program. The average annual gross receipts, based on the firm's last three years of receipts, must not exceed the small business size standard established by the Authority for the services or goods that will be provided in an Authority contract. The receipts of all affiliates are counted in determining size. Business concerns are affiliates of each other when, either directly or indirectly, (1) one concern controls or has the power to control the other, or (2) a third party (or parties) has the power to control both. Consideration is given to such factors as common ownership and management, contractual relationships and overlapping authority.
