The permissible debt to equity ratio of a joint venture is regulated depending on the size of the joint venture. In situations where the sum of debt and equity is less than US$ 3 million, equity must constitute 70% of the total investment. In joint ventures where the sum of the debt and equity is more than US$ 3 million but less than US$ 10 million, then equity must constitute at least half of the total investment. In cases where the sum of the debt and equity is more than US$ 10 million but less than US$ 30 million, 40% of the total investment must be in the form of equity. When the total investment exceeds US$ 30 million, at least a third of total investment must be equity.
