In this video, we walk through a bond valuation problem involving a perpetuity. The scenario involves a series of $140 payments every five years, starting in year one, with a quoted discount rate of 8.3378%, compounded quarterly. The goal is to calculate the present value of this perpetuity, which spans multiple years. We cover important concepts like adjusting quoted rates to effective annual rates and periodic rates, as well as the nuances of perpetuity valuation, such as how payments spanning several years affect the calculation. By the end, you'll understand how to adjust the discount rate for multi-year perpetuities and how to calculate present value effectively.
