be issued at the third year. The bond is redeemable at par on December 31, 2011<br />
at the end of 5 years. Required :<br />
(i) Estimate the current yield and the YTM of the bond.<br />
(ii) Calculate the duration of the NCD.<br />
(iii) Assuming that intermediate coupon payments are, not available for<br />
reinvestment calculate the realised yield on the NCD. (Nov. 2008)<br />
Answer 7<br />
(i) Current yield ( per half year ) = ---------x100 = 7.7778%<br />
90<br />
i.e. 7.7778x2 i.e. 15.5556 % p.a. half-yearly compounded.<br />
Calculation of YTM :<br />
Approximately rate of return = (80/5)/(90)] x 100= 17.78 p.a.<br />
Let YTM is 18% p.a. compounded half-yearly.<br />
Value of bond =<br />
7(annuity for 10 periods at 9%) + 100 ( PVF of period 10 at 9%)<br />
= 7 (6.418) + 100(0.422) = 87.13<br />
NPV at 18% ( compounded half yearly ) : 87.13 – 90 = - 2.87<br />
Let YTM is 17% p.a. compounded half-yearly.<br />
7 7 100<br />
Value of bond = ------- + …………… + -------- + ----------<br />
(1.085) 1 (1.085) 10 (1.085) 10<br />
= 90.16<br />
NPV at 17% ( compounded half yearly ) : 90.16 – 90 = 0.16<br />
0.16<br />
YTM (half-yearly) = 8.50 + -------------- x 0.50 = 8.5264<br />
0.16 – ( -2.87)<br />
YTM = 8.5264 x 2 = 17.05% p.a. half yearly compounded.<br />
