Answer:
Invoice price = $999.38
Step-by-step explanation:
DATA
coupon rate = 6.23%
clean price = $989
par value = $1,000
invoice price = ?
Solution
As mentioned above the interest is paid semi-annually and there are 4 months to the next coupon payment it means that the last coupon payment was made 2 months ago therefore the accrued interest will be paid for 2 months.
Working
6 months coupon payment = $1000 x 6.23% x 6/12
6 months coupon payment = $31.15
Accrued interest for 2 months = $31.15 x 2/6
Accrued interest for 2 months = $10.38
Invoice price = Clean price + Accrued interest
Invoice price = $989 + $10.38
Invoice price = $999.38
