Providence Industries has an outstanding debenture of $25 million that was issued when flotation costs could be expensed immediately. It carries a coupon rate of 10 percent and has 15 years to maturity. Currently, similar risk bonds are yielding 9 percent over a 15-year period, and Providence is wondering if a refunding would be economically sound. The existing debenture has a call premium of 5 percent at present. It is estimated that a new issue would require underwriting costs of $470,000 and other costs of $80,000. No overlap period would be required. Providence Industries has a tax rate of 25 percent. Its cost of capital is 16 percent. a-1. Compute the discount rate.
