Tolls provide the Concessionaire with the revenues required to recoup the cost of investments service and repay the debt and meet capital and operating costs.
All capital regardless of whether it comes from debt or equity sources has a cost associated with it. There would therefore be an impact on the level of tolls whichever source capital is used.
Recognizing however that the cost of debt is normally different to that of equity different ratios of debt and equity in the capital structure will have different levels of impact on tolls.
