Hybrid instruments can materially shift WACC and leverage ratios. The safest approach - and the most defensible - is to classify them based on their contractual cash flow features and seniority, not their accounting label.
Why Hybrids Matter
Misclassifying a hybrid as pure debt understates WACC. Misclassifying it as pure equity can overstate leverage capacity. Both errors have meaningful consequences for valuation and credit analysis.
Perpetual or Tier 1 Sukuk
Perpetual sukuk with subordinated claims and discretionary (deferrable) distributions sit at the boundary between debt and equity. Because these instruments share features with both:
- Assign partial equity credit - the common approach is to test equity credit of 0%, 50%, and 100%, and show WACC sensitivity across that range
- Do not treat them as simple vanilla debt in the WACC weights
For bank-issued Tier 1 capital sukuk, the regulatory treatment provides useful guidance on the equity/debt split, though valuation treatment and regulatory capital treatment do not always align.
Shareholder Funding
Loans from controlling shareholders or related parties require careful classification. The key questions are:
- Is there a defined repayment obligation?
- Is the instrument subordinated to other creditors?
- Are payments discretionary or contractually required?
If the instrument behaves like equity in substance - discretionary payments, no fixed maturity, deeply subordinated - treat part of it as equity in the capital structure and document the reasoning.
Convertibles
Convertible instruments (bonds or sukuk with conversion rights) are best handled through scenario analysis:
- Debt-only scenario - instruments convert at maturity only if forced
- Equity conversion scenario - instruments convert upon a trigger or election
Avoid treating conversion as a single-point forecast. Show both scenarios in the WACC weights and the resulting valuation range.
Presenting Results
Show WACC under different equity credit assumptions for any hybrid in the capital structure. This keeps the model honest and makes the uncertainty visible to any reviewer.
