1. Find the present value of a payment stream of $100 per year for the first fifteen years and $200 per year for the next five years, given a 12% discount rate.

There are two streams of cash flow - $100 and $200. We find the present value separately for the two and then add them up. Both the streams are an annuity and so we use the PVIFA table to get the PV factor and find the present value.

a. $100 for 15 years. This starts at the beginning and so

PV = 100 X PVIFA (15,12%) = 100 X 6.8109 = $681.09

b. We get $200 each year from year 16 onwards for 5 years. We first find the PV in year 15 and then again discount to now

PV in year 15 = 200 X PVIFA (5,12%) = 200 X 3.6048 = 720.96

Now this is a lump sum which we can discount to get the PV today

PV today = 720.96/(1+12%)^15 = 131.72

Total PV = 681.09+131.72 = $812.80

2.A company stock was priced at $15 per share two years ago. The stock sold for $13 last year and now it sells for $18. What was the total return for owning this company stock ...
