Answer:
Bonds
Step-by-step explanation:
Bonds fit all of Marlon's needs since:
- He can know the interest rate up front, e.g. the coupon rate of the bond, or the market rate if the bond is purchased at a premium or discount.
- Some bonds have a very remote maturity date, up to 30 years (e.g. US securities) and that is a long period of time.
- Even though Marlon can cash his money before the bond matures (he can sell them), it is something that takes a few days and must be done by a broker.
- Bonds are very secure investments, specially US securities which are considered the most secure investment in the world, but even corporate bonds are considered secure. In case the firm goes is liquidated, bondholders receive their money before preferred stockholders and common stockholders.
