The Calgary Company is thinking of modifying its working capital assets policy

The Calgary Company is thinking of modifying its working capital assets policy. Fixed assets are $600,000, sales are projected at $3 million, the EBIT/sales ratio is projected at 15 percent, the interest rate is 10 percent on all debt, the federal-plus-state tax rate is 40 percent, and Calgary plans to maintain a 50 percent debt-to-assets ratio. Three alternative current asset policies are under consideration; 40, 50 and 60 percent of projected sales. What is the expected return on equity under each alternative?
