Ronaldio Corporation plans to issue a $$1,000$ par value, $20-$year noncallable bond with a $7\mathrm{.}00\%$ annual coupon, paid semiannually.$$ The company's marginal tax rate is $44\mathrm{.}00\%,$ but Congress is considering a change in the corporate tax rate to $34\%.$ By how much would the component cost of debt used to calculate the WACC change if the new tax rate was adopted?
