Solutions to Questions and Problems
NOTE: All end of chapter problems were solved using a spreadsheet. Many problems require multiple
steps. Due to space and readability constraints, when these intermediate steps are included in this
solutions manual, rounding may appear to have occurred. However, the final answer for each problem is
found without rounding during any step in the problem.
Basic
1. The yield to maturity is the required rate of return on a bond expressed as a nominal annual interest
rate. For noncallable bonds, the yield to maturity and required rate of return are interchangeable
2. Price and yield move in opposite directions; if interest rates rise, the price of the bond will fall. This

3. The price of any bond is the PV of the interest payments, plus the PV of the par value. Notice this
problem assumes an annual coupon. The price of the bond will be:
We would like to introduce shorthand notation here. Rather than write (or type, as the case may be)
which stands for Present Value Interest Factor
which stands for Present Value Interest Factor of an Annuity
These abbreviations are shorthand notation for the equations in which the interest rate and the
4. Here we need to find the YTM of a bond. The equation for the bond price is:
Notice the equation cannot be solved directly for R. Using a spreadsheet, a financial calculator, or
trial and error, we find:
If you are using trial and error to find the YTM of the bond, you might be wondering how to pick an
Approximate YTM = [Annual interest payment + (Price difference from par/Years to maturity)]/
[(Price + Par value)/2]
Solving for this problem, we get:
This is not the exact YTM, but it is close, and it will give you a place to start.

CHAPTER 7 - 4
5. Here we need to find the coupon rate of the bond. All we need to do is to set up the bond pricing
equation and solve for the coupon payment as follows:
Solving for the coupon payment, we get:
The coupon payment is the coupon rate times par value. Using this relationship, we get:
6. To find the price of this bond, we need to realize that the maturity of the bond is 14 years. The bond
was issued 1 year ago, with 15 years to maturity, so there are 14 years left on the bond. Also, the
7. Here we are finding the YTM of a semiannual coupon bond. The bond price equation is:
Since we cannot solve the equation directly for R, using a spreadsheet, a financial calculator, or trial
and error, we find:
Since the coupon payments are semiannual, this is the semiannual interest rate. The YTM is the APR
of the bond, so:
8. Here we need to find the coupon rate of the bond. All we need to do is to set up the bond pricing
equation and solve for the coupon payment as follows:
Solving for the coupon payment, we get:
Since this is the semiannual payment, the annual coupon payment is:
page-pf5
CHAPTER 7 - 5
And the coupon rate is the annual coupon payment divided by par value, so:
9. To find the price of a zero coupon bond, we need to find the value of the future cash flows. With a
zero coupon bond, the only cash flow is the par value at maturity. We find the present value
assuming semiannual compounding to keep the YTM of a zero coupon bond equivalent to the YTM
of a coupon bond, so:
10. To find the price of this bond, we need to find the present value of the bond’s cash flows. So, the
price of the bond is:
11. To find the price of this bond, we need to find the present value of the bond’s cash flows. So, the
price of the bond is:
12. The approximate relationship between nominal interest rates (R), real interest rates (r), and inflation
(h) is:
R r + h
The Fisher equation, which shows the exact relationship between nominal interest rates, real interest
rates, and inflation is:
(1 + R) = (1 + r)(1 + h)

rates, and inflation is:

14. The Fisher equation, which shows the exact relationship between nominal interest rates, real interest
rates, and inflation is:
(1 + R) = (1 + r)(1 + h)
15. The Fisher equation, which shows the exact relationship between nominal interest rates, real interest
rates, and inflation is:
(1 + R) = (1 + r)(1 + h)
16. The coupon rate, located in the second column of the quote, is 4.500 percent. The bid price is:
The previous day’s ask price is found by:
Previous day’s asked price = 127.4375 = 127.4375%
17. This is a premium bond because it sells for more than 100 percent of face value. The dollar asked
price is:
The current yield is the annual coupon payment divided by the price, so:
Current yield = Annual coupon payment/Price
page-pf7
CHAPTER 7 - 7
The bid-ask spread is the difference between the bid price and the ask price, so:
In dollars, the bid-ask spread is:
Intermediate
18. Here we are finding the YTM of annual coupon bonds for various maturity lengths. The bond price
equation is:
P = C(PVIFAR%,t) + $1,000(PVIFR%,t)
X: P0 = $37(PVIFA3.4%,26) + $1,000(PVIF3.4%,26) = $1,051.24
P1 = $37(PVIFA3.4%,24) + $1,000(PVIF3.4%,24) = $1,048.69
P13 = $1,000
Y: P0 = $34(PVIFA3.7%,26) + $1,000(PVIF3.7%,26) = $950.45
P1 = $34(PVIFA3.7%,24) + $1,000(PVIF3.7%,24) = $952.82

CHAPTER 7 - 8
All else held equal, the premium over par value for a premium bond declines as maturity approaches,
and the discount from par value for a discount bond declines as maturity approaches. This is called
“pull to par. In both cases, the largest percentage price changes occur at the shortest maturity
lengths.
Also, notice that the price of each bond when no time is left to maturity is the par value, even though
the purchaser would receive the par value plus the coupon payment immediately. This is because we
calculate the clean price of the bond.
19. Any bond that sells at par has a YTM equal to the coupon rate. Both bonds sell at par, so the initial
YTM on both bonds is the coupon rate, 7.3 percent. If the YTM suddenly rises to 9.3 percent:
The percentage change in price is calculated as:
Percentage change in price = (New price – Original price)/Original price
If the YTM suddenly falls to 5.3 percent:
PSam = $36.50(PVIFA2.65%,6) + $1,000(PVIF2.65%,6) = $1,054.81
All else the same, the longer the maturity of a bond, the greater is its price sensitivity to changes in
interest rates.

20. Initially, at a YTM of 6 percent, the prices of the two bonds are:
If the YTM rises from 6 percent to 8 percent:
The percentage change in price is calculated as:
Percentage change in price = (New price – Original price)/Original price
If the YTM declines from 6 percent to 4 percent:
PJ = $15(PVIFA2%,28) + $1,000(PVIF2%,28) = $893.59
All else the same, the lower the coupon rate on a bond, the greater is its price sensitivity to changes
in interest rates.
21. The current yield is:
Current yield = Annual coupon payment/Price
The bond price equation for this bond is:
Using a spreadsheet, financial calculator, or trial and error we find:

CHAPTER 7 - 10
This is the semiannual interest rate, so the YTM is:
The effective annual yield is the same as the EAR, so using the EAR equation from the previous
chapter:
22. The company should set the coupon rate on its new bonds equal to the required return. The required
return can be observed in the market by finding the YTM on the outstanding bonds of the company.
So, the YTM on the bonds currently sold in the market is:
Using a spreadsheet, financial calculator, or trial and error we find:
This is the semiannual interest rate, so the YTM is:
23. Accrued interest is the coupon payment for the period times the fraction of the period that has passed
since the last coupon payment. Since we have a semiannual coupon bond, the coupon payment per
And we calculate the clean price as:
Clean price = Dirty price – Accrued interest
