Last year Ann Arbor Corp had $125,000 of assets (which equals total invested capital), $305,000 of sales, $21,000 of net income, and a debt-to-total-capital ratio of 37.5%. The new CFO believes that a new computer program will enable the company to reduce costs and thus raise net income to $33,000. The firm finances using only debt and common equity. Assets, total invested capital, sales, and the debt-to-capital ratio would not be affected. By how much would the cost reduction improve the ROE? Do not round your intermediate calculations.
