A corporate bond bought at a discount will provide a capital gain at maturity, as the investor receives the par value, which is higher than the purchase price. The feedback from the document states:
"Bond prices are quoted using an index with a base value of 100. A bond trading at 100 is said to be trading at face value, or par. A bond trading below par, say at a price of 98, is said to be trading at a discount... So if you buy a bond at a discount, at maturity, you will receive the par or face value. The difference between the discounted price and the par value received at maturity is considered a capital gain."

According to the MFDA Rules, a Dealing Representative must not accept any purchase orders from a client until the Branch Manager or other designated person has reviewed and approved the New Client Application Form (NCAF) for the client. This is to ensure that the Dealing Representative has obtained and verified all the necessary information about the client, such as identity, investment objectives, risk tolerance, financial situation, and suitability of investments. The review and approval of the NCAF must be completed before any trades are executed for the client, unless there are exceptional circumstances that justify a delay. In this case, Quintin should have waited for Lupita's approval of the NCAF before placing the purchase order for Reginald.
