formula and computation

1. If a company has a $1,000 face value bond with a 6% semi annual coupon that is trading at $975, then is the YTM more likely to be 5.5% or 6.5% ? 2. Calculate the effective annual rate of the cost of the bond in Question 1. 3. If this same company had a \$60 million bank loan with a current interest rate of 7%, and had 40,000 bonds on issue, what is the after tax cost of debt? (Assume the tax rate is 30%.)
