To calculate the HPY, we need to find the interest rate that equates the price we paid for the bond
with the cash flows we received. The cash flows we received were $54 each year for two years,
31. The price of any bond (or financial instrument) is the PV of the future cash flows. Even though Bond
M makes different coupons payments, to find the price of the bond, we find the PV of the cash flows.
The PV of the cash flows for Bond M is:
32. In general, this is not likely to happen, although it can (and did). The reason this bond has a negative
YTM is that it is a callable U.S. Treasury bond. Market participants know this. Given the high coupon
33. To find the present value, we need to find the real weekly interest rate. To find the real return, we need
to use the effective annual rates in the Fisher equation. So, we find the real EAR is:
(1 + R) = (1 + r)(1 + h)
1 + .075 = (1 + r)(1 + .032)
r = .0417, or 4.17%
34. To answer this question, we need to find the monthly interest rate, which is the APR divided by 12.
We also must be careful to use the real interest rate. The Fisher equation uses the effective annual rate,
so, the real effective annual interest rates and the monthly interest rates for each account are:
Stock account:
(1 + R) = (1 + r)(1 + h)
1 + .07 = (1 + r)(1 + .04)
r = .0288, or 2.88%
APR = m[(1 + EAR)1/m – 1]
APR = 12[(1 + .0288)1/12 – 1]
APR = .0285, or 2.85%
Now we can find the future value of the retirement account in real terms. The future value of each
account will be:
Stock account:
FVA = C {(1 + r )t – 1]/r}
Bond account:
FVA = C {(1 + r )t – 1]/r}
The total future value of the retirement account will be the sum of the two accounts, or:
Account value = $1,196,731.96 + 170,316.78
Account value = $1,367,048.74
Now we need to find the monthly interest rate in retirement. We can use the same procedure that we
used to find the monthly interest rates for the stock and bond accounts, so:
Now we can find the real monthly withdrawal in retirement. Using the present value of an annuity
equation and solving for the payment, we find:
PVA = C({1 – [1/(1 + r)]t }/r )
35. In this problem, we need to calculate the future value of the annual savings after the five years of
operations. The savings are the revenues minus the costs, or:
Savings = Revenue – Costs
Since the annual fee and the number of members are increasing, we need to calculate the effective
growth rate for revenues, which is:
The revenue will grow at 9.18 percent, and the costs will grow at 2 percent, so the savings each year
for the next five years will be:
Year

Costs
Savings

$178,204.00
2
333,767.63
130,050.00
203,717.63
Now we can find the value of each year’s savings using the future value of a lump sum equation, so:
FV = PV(1 + r)t
Year

$178,204.00(1 + .09)4 =
