Answer: has not taken custody of the fund of the customer and must also keep a record of the check he or she received.
Step-by-step explanation:
From the question, we are told that an investment adviser is opening the mail and receives a check from a customer for $8,000, however the adviser shows no balance due from the customer - the check was mailed in error to the adviser. We are further told that five business days later, the investment adviser mails the check back to the customer.
Under NASAA rules, the investment adviser has not taken custody of the fund of the customer and must also keep a record of the check he or she received. The check was received but has been returned. He must also have a copy of the check in case there is argument of further explanation to be made.
