Evaluate the following statements regarding annuities and perpetuities: Statement 1: A Perpetual Annuity, or perpetuity, is an infinite series of regular cash flows continuing forever; its present value is calculated by dividing the periodic payment by the periodic discount rate. Statement 2: If a perpetuity has growing cash flows (at a fixed percentage), the present value is calculated by subtracting the growth rate from the discount rate in the denominator. Statement 3: The present value of a deferred annuity is calculated by first finding the value of the annuity at the start of the payments and then discounting that value to the actual present day. Identify the correct statement regarding their conceptual and mathematical validity:
- 1Statements 2 and 3 are correct, but Statement 1 is incorrect.
