Practice Problem Worksheet Using Excel Formulas |
An understanding of bond characteristics and of bond cash flows is necessary to understand the time value of money effects on bonds and their valuation. Accordingly, it is recommended you employ your knowledge of time value of money principles (just studied in Week 2) and you also need to thoroughly read and understand Chapter 7, "Valuing Bonds," from your M: Finance text before reviewing the following problems and solutions. |
Bond Valuation |
Solving for the Bond Valuation: |
Bond Val 1) Here is a simple bond valuation problem: |
What is the price of a 8.0% coupon bond with 12 years left to maturity and a current market rate of interest of 6.8%. The correct answer is $1,097.37 determined below. Assume semi-annual interest payments and assume $1,000 par value, unless advised otherwise. |
Solution: First, identify this as a bond valuation problem and we are to find the bond's present value. (The bond's present value is requested by such wording as "what is the price" or "compute the price." Inferred in such statements is "what is the price NOW," i.e., what is it's present value.) |
Important Notice: Be advised most bonds usually pay interest on a semi-annual basis, assume this for any bond problem in this course unless you are advised otherwise. Accordingly, we will use the standard Excel, financial formula, and we will adjust our input figures to account for semi-annual compounding. |
Important Notice: Make the following adjustments to the inputs into the financial formula function to adjust for semi-annual compounding: |
|
1) Adjust the interest rate: The 6.8% annual market rate divided by 2 compounding periods per year equals a 3.4% semi-annual rate. Enter 3.4% as the interest rate. |
|
2) Adjust the number of time periods: In a 12 year annual time period, there are 24 semi-annual time periods (12 x 2 = 24) Enter 24 as the number of periods. |
|
3) Adjust the coupon (interest) payment: The 8.0% coupon equates to an annual coupon interest payment of $80. ($1,000 par value (assume $1,000 par unless otherwise indicated) times the 8.0% coupon rate = $80 annual interest payment. There are two semi-annual periods on a year, so adjust the $80 annual payment to reflect a $40 semi-annual payment. (Enter 40 as the payment.) |
|
4) FV and PV amounts do not require compounding frequency adjustments. |
Solution: Next identify the variables to be entered into the formula: |
The interest rate: The adjusted market rate of interest = 3.4% (or 0.034 expressed as a decimal) |
The number of time periods: The adjusted time periods are N = 24 |
The annuity payment: The adjusted annuity payment is $40: PMT = $40 |
The future value: FV = 1,000 (This represents the {future} value of the bond at maturity.) |
Solution: Next using the Excel, Formulas, Financial, PV formula that reads as follows: |
PV = (Int rate, Number of periods, annuity payment, Future Value) |
Solution inputting the numbers into the Excel PV formula in the exact order prescribed by the formula (click on Cell B56 to see the contents of the cell as inputted): |
PV = |
($1,097.37) |
(Note that PV is solved showing it as a negative number. This is because of the specific mathematical formula that is used to solve the equation and represents that $1,097.37 must be paid out (an outflow) in order to receive the series of $40 interest payment (inflow) and to receive the $1,000 par value payment (inflow) at maturity. Even though the Excel mathematical equation solves the PV as a negative number, one should simply refer to the PV as $1,097.37 … without reference to it as a negative number.) |
Bond Val 2) Here is a bond valuation practice problem: |
What is the price of a 7.0 percent coupon bond with 6 years left to maturity and a current market rate of interest of 8.2 percent. Assume interest payments are paid semiannually. The correct answer is $944.01 … determined below. |
PV = |
($944.01) |
Bond Val 3) Here is a bond valuation practice problem for a zero coupon bond: |
What is the price of a zero coupon bond that matures in 14 years and the market rate of interest of 6.4 percent. The correct answer is $413.97 … determined below. Assume semi-annual compounding. |
Calculate this problem the same as the above two bond valuation problems; however, there is no interest paid throughout the life of the bond (hence its name zero coupon.) So, enter "0" in the payment portion of the formula. |
PV = |
($413.97) |
Bond Yield to Maturity |
Solving for Bond Yield to Maturity |
BOND YTM 1) Here is a simple bond yield to maturity (YTM) problem: |
A 5.0 percent coupon bond with 9 years left to maturity is offered for sale at $952.52. What is this bond's yield to maturity. Assume interest payments are paid semiannually and the par value of the bond is $1,000. The correct yield to maturity answer is 5.68% … determined below. |
Solution: First, identify this is a bond yield to maturity problem (this is determined because we are asked to solve for the bond's yield to maturity.) |
|
Solution: Next identify the known variables and adjust for semi-annual compounding: |
The number of time periods: The adjusted time periods are N = 18 (9 x2) |
The annuity payment: The adjusted coupon payment is ($1,000 x .05 = $50); ($50 / 2) : PMT = $25 |
The present value: PV = 952.52 (This represents the current price {present value} of the bond.) Enter present value amount as a negative number to differentiate cash outflows from inflows. |
The future value: FV = 1,000 (This represents the {future} value of the bond at maturity.) |
Solution: Next using the Excel, Formulas, Financial, RATE formula that reads as follows: |
Rate = (Number of periods, coupon payment amount, Present Value {enter PV as a negative number to differentiate cash inflows from outflows}, Future Value) |
Partial solution inputting the numbers into the Excel RATE formula in the exact order prescribed by the formula (click on Cell C115 AND C116 to see the contents of the cell as inputted): |
semi annual RATE |
|
3% |
You need to adjust the C115 cell to allow showing additional decimals (at least 4 decimal places) as reflected in cell C116. |
semi annual RATE |
|
2.84% |
|
WARNING … WE ARE NOT YET FINISHED WITH THIS PROBLEM! |
What we have just calculated is a semi-annual rate. Since yield to maturity always means an annual return, we need to multiply the semi-annual rate to adjust for 2 semi-annual time periods per year. (2.84% x 2 = 5.68%) 5.68% reflects the bond's Yield to Maturity (YTM.) |
Bond YTM |
5.68% |
(Make sure you change the number of decimals in the formula cell so you show at least 4 decimal places as is shown to the left, otherwise, your response would show 6% and that is not sufficiently exact and would be marked as incorrect.) |
BOND YTM 2) Here is a bond yield to maturity (YTM) practice problem: |
A 8.5 percent coupon bond with 11 years remaining to maturity is priced for sale at $1,252.52. What is this bond's yield to maturity. Assume interest payments are paid semiannually. The correct yield to maturity answer is 5.42% … determined below. |
semi annual RATE |
|
3% |
You need to adjust the C137 cell to allow showing additional decimals (at least 4 decimal places) as reflected in cell C138. |
semi annual RATE |
|
2.71% |
What we have just calculated is a semi-annual rate. Since yield to maturity always means an annual return, we need to multiply the semi-annual rate to adjust for 2 semi-annual time periods per year. (2.71% x 2 = 5.42%) 5.42% reflects the bond's Yield to Maturity (YTM.) |
Bond YTM |
5.42% |
(Make sure you change the number of decimals in the formula cell so you show at least 4 decimal places as is shown to the left, otherwise, your response would show 5% and that is not sufficiently exact and would be marked as incorrect.) |
