OPTIMAL CAPITAL STRUCTURE The optimal capital structure for a company should be the mix of equity‚ debt and hybrid instruments that minimizes the overall cost of funding‚ i.e. it should minimize the company’s weighted average cost of capital. In practice‚ however‚ it is not possible to specify this optimal capital structure exactly‚ for any individual company. It clearly makes sense to obtain funds at the lowest possible cost. In the long run‚ debt is cheaper than equity. However‚ when a company’s
