Explanation
Keith would not have to register as an agent since he is a salaried employee of a county in Massachusetts selling county-issued bonds to the public. He is not representing a broker-dealer; he is not receiving a commission on the bonds he sells; and he is selling exempt (government-issued) securities. John receives a commission on his sales, so he is considered to be an agent. Stefan is a sales representative employed by a broker-dealer, which makes him an agent under USA guidelines. Even though Preetham is part-owner of the broker-dealer for which he is effecting transactions, he is acting as an agent in doing so.
