Two corporate bonds, issued respectively by F Ltd and G Ltd, have the same face value of$10,000 and the same term to maturity of 7 years. F Ltd’s bonds have a coupon rate of 8% perannum, payable half-yearly, and G Ltd’s bonds have a coupon rate of 7.8% per annum, payablebi-monthly (that is, every 2 months). Calculate the effective annual return (EAR) on each bond.
