A debt limitation may take a variety of forms, depending on the circumstances of the debt issue. For financially sound firms, lenders may only want to maintain the current levels of leverage and implement a covenant relating to the debt-service coverage ratio. This would allow the firm to borrow more funds when it increases its net income.
If the firm appears risky, lenders may not want it to incur additional debt. The covenant may specify a maximum level of debt, despite any growth in operations. In more extreme cases, the lenders may demand that no additional debt be incurred until their bonds are repaid.
