A guaranteed return of dollars. What those dollars are worth is not guaranteed. Imagine Tesla would hand out a certain type of share that after 10 years turns into 2 shares. Nobody would call that a risk free return. Because you don't know how much dollars you will get for those two shares. The same with dollars. You don't know how much Tesla shares you will get for those dollars.
