Ace Industrial Machines issued 195,000 zero coupon bonds four years ago. The bonds originally had 30 years to maturity with a yield to maturity of 5.2 percent. Interest rates have recently decreased, and the bonds now have a yield to maturity of 4.9 percent. If the company has a $73 million market value of equity, what weight should it use for debt when calculating the cost of capital? (Do not round intermediate calculations and round your answer to 4 decimal places, e.g., .1616.)
