You are looking at two firms in the same industry. High Performance Tire Co. has a profit margin of 10% and All-Year Tires has a profit margin of 8%. High Performance Tire Co.'s total debt to total capital ratio [measured as (Short-term debt + Long-term debt)/(Debt + Preferred stock + Common equity)] is 70% versus one of 20% for All-Year Tires. Based only on these two facts, you cannot reach a conclusion as to which firm is better managed, because the difference in debt, not better management, could be the cause of High Performance Tire Co.'s higher profit margin.
