ROE = NI/EBT * EBT/EBIT * EBIT/Revenue * Asset Turnover * Company Equity Multiplier
-15.76% = 76.00% * 138.12% * -7.17% * 48.70% * 4.65



ROA = Net Profit Margin * Asset Turnover
-3.67% = -7.53% * 48.70%



The company's tax burden is (Net income ÷ Pretax profit). This is the proportion of the company's profits retained after paying income taxes. [NI/EBT]
The company's interest burden is (Pretax income ÷ EBIT). This will be 1.00 for a firm with no debt or financial leverage. [EBT/EBIT]
The company's operating income margin or return on sales (ROS) is (EBIT ÷ Revenue). This is the operating income per dollar of sales. [EBIT/Revenue]
The company's asset turnover (ATO) is (Revenue ÷ Average Total Assets).
The company's equity multiplier is (Average Total Assets ÷ Average Total Equity). This is a measure of financial leverage.

ROE = (Profit margin)*(Asset turnover)*(Equity multiplier) = (Net profit/Sales)*(Sales/Average Total Assets)*(Average Total Assets/Average Equity) = (Net Profit/Equity)
