INTEREST RATES AND BOND
VALUATION
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
NOTE: Most problems do not explicitly list a par value for bonds. Even though a bond can have any par
value, in general, corporate bonds in the United States will have a par value of $1,000. We will use this
par value in all problems unless a different par value is explicitly stated.
3.
The price of any bond is the PV of the interest payment, plus the PV of the par value. Notice this
problem assumes an annual coupon. The price of the bond will be:
P = $75({1 – [1/(1 + .0875)]
10
} / .0875) + $1,000[1 / (1 + .0875)
10
] = $918.89
We would like to introduce shorthand notation here. Rather than write (or type, as the case may be)
the entire equation for the PV of a lump sum, or the PVA equation, it is common to abbreviate the
equations as:
