Seattle Health Plans currently uses zero-debt financing. Its operating profit is $2 million, and it pays taxes at a 25 percent rate. It has $9 million in assets and, because it is all-equity financed, $9 million in equity. Suppose the firm is considering replacing 57 percent of its equity financing with debt financing that bears an interest rate of 7 percent. What impact would the new capital structure have on the firm's ROE (return on equity)?

(Enter your answer as a percentage, rounded to 2 decimal places. If ROE would increase, enter your answer as a positive number. If ROE would decrease, enter your answer as a negative number. Do not include % sign. For example an increase in ROE of 12.3456% would be entered as 12.35.)
