Final answer:
Arthur must affiliate with a registered investment adviser to become an IAR but does not have to terminate his agent registration. He can be associated with different firms for his IAR and agent roles, subject to approval.
Step-by-step explanation:
Under the provisions of the Uniform Securities Act, if Arthur wishes to become an investment adviser representative (IAR), he must affiliate with a registered investment adviser. It is not a requirement to terminate his registration as an agent with Fast Execution Brokers (FEB). Therefore, the correct answer to Arthur's query would be that he can still direct client securities transactions to FEB as an agent, but to earn fees for giving advice as an IAR, he must be affiliated with a registered investment adviser. However, this does not preclude him from being an agent and an IAR for different firms, as long as the firms are aware of and approve the dual registration.
When planning to speak with the manager of the local branch of National Investment Advisers, Inc. (NIAI) about becoming an IAR, Arthur should clarify these points and discuss the potential compliance and conflict of interest concerns that might arise with dual registration.
