Fifteen years ago, Roop Industries sold $400 million of convertible bonds. The bonds had a 40-year maturity, a 5.75% coupon rate, and paid interest annually. They were sold at their $1,000 par value. The conversion price was set at $63.50, and the common stock price was $56 per share. The bonds were subordinated debentures and were given an A rating; straight nonconvertible debentures of the same quality yielded about 8.40% at the time Roop's bonds were issued.

1. Calculate the premium on the bonds that is, the percentage excess of the conversion price over the stock price at the time of issue. Do not round intermediate calculations. Round your answer to two decimal places.

2. What is Roop's annual before-tax interest savings on the convertible issue versus a straight-debt issue? Do not round intermediate calculations. Enter your answer in millions. For example, an answer of $25,500,000 should be entered as 25.5. Round your answer to two decimal places.

   $ million per year

3. At the time the bonds were issued, what was the value per bond of the conversion feature? Do not round intermediate calculations. Round your answer to the nearest cent.

   $ per bond

4. Suppose the price of Roop's common stock fell from $56 on the day the bonds were issued to $38.50 now, 15 years after the issue date (also assume the stock price never exceeded $63.50). Assume interest rates remained constant. What is the current price of the straight-bond portion of the convertible bond? Do not round intermediate calculations. Round your answer to the nearest cent. Enter all amounts as a positive number.
