The common stock and debt of Northern Sludge are valued at $$58$ million and $$42$ million, respectively. Investors currently require a

$16\mathrm{.}9\%$ return on the common stock and an $6\mathrm{.}8\%$ return on the debt. If Northern Sludge issues an additional $$22$ million of common

stock and uses this money to retire debt, what happens to the expected return on the stock? Assume that the change in capital

structure does not affect the interest rate on Northern's debt and that there are no taxes.
