Structuring Infrastructure Debt Facilities

Designs infrastructure lending with mini-perm structures, cash sweep mechanics, and maintenance/distribution covenants for greenfield, brownfield, and PPP infrastructure projects.

When To Use

• Structuring senior secured project debt for infrastructure assets (transport, energy, water, social infrastructure)
• Designing mini-perm or fully-amortizing tenor profiles matched to concession/asset life
• Building covenant packages with maintenance tests, distribution lock-ups, and cash sweep triggers
• Analyzing existing infrastructure credit agreements for refinancing, restructuring, or amendment
• Evaluating debt sizing and sculpting against base-case and downside cash flow projections
• Advising on PPP availability-payment or toll-revenue financing structures

Inputs To Gather

• Project description: asset type, greenfield vs. brownfield, concession term or useful life, offtake/revenue model (contracted, merchant, availability-based)
• Financial model outputs: base-case and downside CFADS projections, construction draw schedule, target DSCR/LLCR/PLCR metrics
• Sponsor requirements: target leverage, equity IRR hurdles, distribution frequency preferences, refinancing intent
• Lender market context: bank vs. institutional debt, number of tranches, pricing benchmarks, hedging requirements
• Regulatory/concession constraints: permitted debt levels, step-in rights, change-of-control restrictions, government consent requirements [VERIFY jurisdiction-specific concession terms]
• Security package scope: asset pledges, assignment of project contracts, share pledges, direct agreements with counterparties

Workflow

1. Classify the project profile

   • Determine revenue type: contracted (PPA, offtake, availability payment) vs. merchant vs. hybrid
   • Identify construction risk allocation (EPC fixed-price, alliance, cost-plus)
   • Confirm concession/license term and tail period available for debt repayment

2. Size and sculpt the debt

   • Apply target DSCR to base-case CFADS to derive maximum annual debt service
   • Sculpt repayment profile to match projected cash flow shape (front-loaded, level, or back-loaded)
   • Stress-test under downside scenarios; confirm LLCR and PLCR meet lender minimums (typically LLCR ≥ 1.15–1.25x for contracted assets, ≥ 1.30–1.40x for merchant) [VERIFY against current market benchmarks]
   • Determine mini-perm tenor (typically 5–7 years with soft/hard refinancing triggers) vs. fully-amortizing tenor

3. Design the mini-perm structure (if applicable)

   • Set initial maturity with cash sweep step-ups beginning at the soft mini-perm date
   • Define cash sweep percentages: e.g., 50% of excess cash flow from soft date, stepping to 75–100% at hard mini-perm date
   • Specify margin ratchet or step-up mechanics post-soft mini-perm to incentivize refinancing
   • Address refinancing risk allocation — sponsor equity cure rights, market disruption provisions

4. Build the covenant package

   • Maintenance covenants: set ongoing DSCR floors (e.g., historical and projected DSCR ≥ 1.10–1.20x); specify measurement periods (trailing 12 months, forward-looking 12 months)
   • Distribution test: require minimum DSCR (e.g., ≥ 1.20x historical and projected) plus no outstanding defaults; include lock-up DSCR threshold below which distributions are blocked entirely
   • Reserve accounts: define required balances for debt service reserve (typically 6 months' debt service), maintenance reserve, and insurance proceeds account
   • Additional indebtedness test: cap incremental borrowing by leverage ratio or DSCR impact; require rating agency confirmation for rated transactions
   • Cash waterfall: specify priority of payments — O&M costs → senior debt service → reserve funding → cash sweep (if triggered) → subordinated debt → equity distributions

5. Structure the security package

   • First-priority security over project assets, real property interests, and material project accounts
   • Assignment of key project agreements (offtake/PPA, EPC, O&M, insurance)

Output

Produce a structured infrastructure debt facility report containing:

• Executive summary: asset overview, recommended debt quantum, tenor, and key terms
• Debt sizing table: annual CFADS, debt service, DSCR, LLCR, and PLCR under base and downside cases
• Term sheet outline: facility amount, tenor, amortization profile, mini-perm mechanics (if used), pricing, and key conditions precedent
• Covenant schedule: maintenance DSCR levels, distribution test thresholds, reserve requirements, cash sweep triggers with step-up percentages
• Cash waterfall diagram: sequential priority of payments from project revenue through equity distributions
• Security package summary: list of collateral, assignments, direct agreements, and perfection steps
• Risk flags: identified structural risks (refinancing risk, construction delay, revenue shortfall) with proposed mitigants

Quality Checks

• Confirm DSCR sculpting produces no period below the minimum maintenance covenant level under base case
• Verify LLCR and PLCR calculations use consistent discount rates and cash flow periods
• Check that cash sweep mechanics and distribution lock-up thresholds are internally consistent (lock-up DSCR < distribution DSCR < default DSCR)
• Ensure mini-perm soft/hard dates, margin step-ups, and sweep percentages align and create genuine refinancing incentive
• Validate that the security package covers all material project contracts and accounts; flag any unsecured exposures
• Confirm reserve account sizing matches debt service profile and lender market standards [VERIFY against comparable recent transactions]
• Cross-check covenant definitions (e.g., CFADS, permitted leakage, capital expenditure carve-outs) for consistency between financial model and legal documentation
