3 years ago, an investor purchased a $1000 face, 4.5% semiannual coupon bond with 7 years to maturity priced to yield at 6.5% for $888.94. The reinvestment income that must be generated over the life of the bond for the investor to realize a yield of 6.5% is closest to: a) $72 b) $76 c) $80 d) $83

is the answer b?

how did you figure out the answer?

it is C?? 79.4947 - Dinesh S

dinesh can you post your calculations?

I am going with B: $76 PMT = -22.5 (4.5%/2 * 1000) PV = 0 i = 3.25% (6.5/2) n = 14 (Semiannual pay) FV = ? —> $391 22.5 \* 14 = 315 (Gross amount of coupons) Reinvestment income required = $391.02 - $315 = $76

florinpop, delhirocks this is what I did … 22.5 \* 14 = 315 (Gross Coupon Income) CF0 = 0 C01 = 22.5 (4.5/2*1000) F01 = 13 [14 -1 because you don’t get any interest on the 14th Coupon Payment] I = 3.25 (6.5/2) CPT -> NPV = 235.505 So the difference would be Interest income = 315 - 235.505 = 79.495 Don’t know if anything of this is correct… barthezz, what is the correct answer? - Dinesh S

I just dont know how correct it is to compare sum of cupons at different times with a future or present value first of all the bond has 7 years all togheter or was bought 3y ago and has 7 y to maturity? If it has a life of 7y isn’t the yield 6.5% already? thanks

Logic behind it is this: You are receiving $22.5 every 6 months, which you are taking out as cash, you are not reinvesting them. Therefore, you will get the 6.5% return only if you reinvest those $22.5 payments at 6.5%. So, just calculate the futyre value of those payments at 6.5%, and consider only the return generated by them. That is, their future value minus their sum (14*$22.5), that’s the reinvestment income you need to have to get the 6.5% promised rate. So, in reality when it says you get a return of 6.5%, it is not really correct, unless you assume that you reinvest the payments you receive at the same rate . Dreary

B. Coupon Payments = 315 Yield of 6.5 == >888.94 (1.0325^14)= 1391 Face Value at Maturity = 1000 Reinvestment Income = 1391 – 1000 -315 = 76

Dinesh…I think you get coupon along with the last payment. So if its a 2 year semiannual pay Note @ 5%, its CF will be 50, 50, 50 & 1,050. dinesh.sundrani Wrote: ------------------------------------------------------- > florinpop, delhirocks this is what I did … > > 22.5 \* 14 = 315 (Gross Coupon Income) > > CF0 = 0 > C01 = 22.5 (4.5/2*1000) > F01 = 13 [14 -1 because you don’t get any interest > on the 14th Coupon Payment] > I = 3.25 (6.5/2) > CPT -> NPV = 235.505 > > So the difference would be Interest income = 315 - > 235.505 = 79.495 > > Don’t know if anything of this is correct… > barthezz, what is the correct answer? > > - Dinesh S
