Analysts expect the Rumpel Felt Company to generate EBIT of $20 million annually in perpetuity (starting in one year). Rumpel is all-equity financed and its stockholders require a return of 7%. If Rumple borrows $80 million (interest-only in perpetuity) with a cost of debt of 3%, what return will the stockholders require? Assume Rumpel operates in Utopia where corporate taxes are zero.
