Answer:
YTC = IRR = 12.844% (exact using excle of financial calculator)
using approximation formula: 12.72%
Step-by-step explanation:
The call premium means it were called at 107 of the face value
1,000 x 107/100 = 1,070
The investment was for 1,000
The bond yield a six years annuity of 120
and then called at 1,070
We need to know teh YTC:
Coupon payment =1,000 x 12% = 120
Call Price: 1070
Face Value: 1000
n: 6 years
YTC = 12.7214171%
This method is an aproximation to the YTC
To solve for the YTC we can use excel IRR funtion
we write
-1,000 (investment)
120
120
120
120
120
+1,070+120 = 1,190 (total cashflow at year 6 call price and coupon)
and we calculate IRR selecting this values:
which give us 12.844%
Which is close to our approximation.
