Final answer:
In a perpetuity, returns are earned annually and last indefinitely.
Step-by-step explanation:
In a perpetuity, the returns are earned annually.
A perpetuity is a type of investment that provides a series of identical cash flows that go on indefinitely.
For example, if you invest in a perpetuity that pays $1000 annually with an interest rate of 5%, you will receive $1000 every year for as long as the investment exists.
