The capital stack refers to the layers of debt and equity that are used to finance a project or company. In the context of energy and infrastructure projects, the capital stack can be complex and involve multiple layers of financing. Understanding how these layers interact is crucial for project financing and holdco finance.
The capital stack typically consists of senior debtsubordinated debt and equity. Senior debt has the highest seniority and is typically secured by the project’s assets. Subordinated debt has a lower seniority and is often used to finance specific aspects of the project. Equity is the most junior layer and represents the ownership stake in the project.
Seniority and Covenants
Seniority refers to the order in which creditors are repaid in the event of default. In a typical capital stack, senior debt is repaid first, followed by subordinated debt, and finally equity. Covenants are agreements between the borrower and lender that restrict the borrower’s actions and ensure that the loan is repaid. Covenants can include requirements for debt-to-equity ratiosinterest coverage ratios and cash flow projections.
Cash Waterfalls
A cash waterfall is a mechanism for distributing cash flows from the project to the various layers of the capital stack. The cash waterfall typically prioritizes senior debt repayments, followed by subordinated debt, and finally equity distributions. The cash waterfall is designed to ensure that the project’s cash flows are used to repay debt and cover expenses before distributing profits to equity holders.
Mapping Risks to the Right Tranche
Mapping risks to the right tranche involves identifying the specific risks associated with the project and allocating them to the appropriate layer of the capital stack. For example, construction risk may be allocated to the equity layer, while operational risk may be allocated to the subordinated debt layer. By mapping risks to the right tranche, lenders and investors can better manage their exposure to risk and ensure that the project is financed in a way that is consistent with its risk profile.
Case Studies
Energy and infrastructure projects often involve complex capital stacks with multiple layers of debt and equity. For example, a wind farm project may involve senior debt from a commercial bank, subordinated debt from a private equity firm, and equity from a group of investors. The cash waterfall for the project would prioritize senior debt repayments, followed by subordinated debt, and finally equity distributions. By understanding how the capital stack works and mapping risks to the right tranche, lenders and investors can better manage their exposure to risk and ensure that the project is financed in a way that is consistent with its risk profile.
