Mordecai bought a 3-year 15% Treasury bond on 8 May 2020 at a yield of j2 = 18.6% p.a. Coupons can be reinvested at j2 = 14.0% p.a. The bond will be redeemed at par on the maturity date (face value $100).
a. Calculate the total accumulated value at maturity generated by this bond if Mordecai holds it to maturity and reinvests all coupon payments received at the available rate.
b. Calculate the total realised compound yield (TRCY) of this bond.
c. Decompose the total accumulated value generated by this bond into: original purchase price, coupons, interest on coupons, and capital gain/loss.
d. If Mordecai holds the bond for 2 years and sells it for a yield of j2 = 18.8% p.a., calculate the holding period yield (HPY).
e. Calculate duration of this bond if it is held to maturity.
f.Use the concept of modified duration to estimate the price of the bond if the yield to maturity increases to j2 = 18.7% p.a. im- mediately after Mordecai buys the bond.
g. ]What fixed liability could Mordecai be reasonably confident of paying off in 2 1/2 years’ time? Why? I don't really know how to do part E,F and G, other parts are done
Purchase price of the bond can be calculated using the formula |
PV=(Coupon pmt.*(1-(1+Yield)^-n)/Yield)+(FV/(1+Yield)^n) |
where, coupon pmt.=100*15%/2=$ 7.5 per semi-annual period |
Yield= semi-annual yield = 18.6%/2=9.3% per s/a period |
n= no.of periods to maturity, ie. 3*2=6 s/a periods |
& FV= Face value=$ 100 |
so, PV/Price=(7.5*(1-1.093^-6)/0.093)+(100/1.093^6)= |
92.00 |
S/a period | Coupons recd. | Interest income on re-inv. Of coupons | Face value | Total | FV F at 9.3% per period | FV at end yr. 3 | |

b. Realised compound yield= (Total accumulation/Purchase price)^(1/holding period)-1 |
ie. (160.01/92)^(1/3)-1= |
20.26% |
c..Total accumulated value | 160.01 |

Int. on coupons | 2.625 |
Total accumulated value | 207.64 |
Original purchase price | 92.00 |

d.To find selling price at end of 2 yrs. At the given yield of 18.8% p.a. | |
92=(7.5*(1-1.094^-4)/0.094)+(SP/1.094^4)= | |

91.9971 | 460.0115 |
(Macaulay)Duration of the bond=PV of Time- weighted CFs/Current Market value |
ie. 460.0115/91.9971= |
5.000 |
f. Using the concept of modified duration to estimate the price of the bond if the yield to maturity increases to 18.7%, that is by (18.7%-18.6%=) 0.1% or 0.001 |
Modified duration=Macaulay duration/(1+0.093)= |
ie. 5.00/1.093= |
4.5746 |
Approximate change in price= 4.5746*0.001= |
0.0045746 |
So, when the yield increases to 18.7%, the estimated price will be |
92*(1-0.004575)= |
91.58 |
g. Fixed liability Mordecai could be reasonably confident of paying off in 2 1/2 years’ time= |
By looking at the duration & modified duration, we can see that weighted average time when all the cash flows of the bond are received is 5 semi-annual periods, ie 2.5 years. |
So, Mordecai could reasonably be confident of paying off $ 160 of fixed liability (as in a. above) ---in this 2 1/2 years’ time----as , by that time all monies from the bond would have been received---along with his investment income. |
