Answer:
6.75%
Step-by-step explanation:
Current price = Annual coupon*Present value of annuity factor (7.1%,12) +1000*Present value of discounting factor (7.1%,12)
972 = Annual coupon*7.900528111+$1000*0.439062504
Annual coupon = (972-439.062504)/7.900528111
=$67.46(Approx)
Coupon rate = Annual coupon/Face value
= $67.46/1000
= 6.75%(Approx).
NOTE:
1.Present value of annuity = Annuity [1-(1+interest rate) ^-time period]/rate
= Annual coupon [1-(1.071) ^-12]/0.071
= Annual coupon*7.900528111
2.Present value of discounting factor=1000/1.071^12
= $1000*0.439062504
