Final answer:
The coupon date is not typically included in the description of a corporate fixed income security; rather, the issuer, coupon rate, and maturity date are the standard elements. option (C)
Step-by-step explanation:
The data element that is NOT typically included in the description of a corporate fixed income security, such as a bond, is the coupon date. The typical elements included in the description of a bond are the issuer, who is responsible for paying back the debt; the coupon rate, which is the interest rate the bond will pay; and the maturity date, which is the date on which the bond will mature and the issuer must repay the bond's principal amount.
The coupon date is less commonly specified because coupon payments on fixed income securities often adhere to a standard schedule that is understood upon issuance, such as semi-annual or annual payments, and does not need to be elaborated in every description of the security.
