This assignment delves into the concept of company valuation, focusing particularly on the debt-to-equity ratio as a measure of leverage. It explains how a high debt-to-equity ratio can indicate operational efficiency but also poses financial risks if profits don't cover borrowing costs. The assignment further discusses the optimal capital structure for maximizing company value, where a balanced mix of equity and debt minimizes the weighted average cost of capital (WACC). It emphasizes that the total value of a company comprises preferred equity, common equity, and debt, and any changes in these components affect the overall valuation.
