Which of the following is not a requirement for an agent regarding FINRA Securities registration to sell certain insurance products?

In the context of FINRA regulations concerning securities registration, it's essential to understand that certain insurance products are classified as securities, and selling these products typically requires an agent to hold specific licenses.

Variable life insurance is a hybrid product that combines life insurance with an investment component, making it subject to securities regulations. Consequently, agents must register with FINRA to sell variable life insurance. Similarly, mutual funds are considered securities and their sale also requires proper registration and licensing.

On the other hand, traditional life insurance and modified whole life insurance are standard insurance products that do not involve the investment characteristics found in variable products. Therefore, an agent can sell these types of insurance without the need for FINRA registration. This distinguishes modified whole life insurance as a product that does not require the same regulatory oversight as variable products or mutual funds.

Thus, the correct choice is modified whole life insurance because it does not require an agent to obtain FINRA securities registration, making it less complex from a regulatory perspective compared to the other options listed.
