Introduction to Debt Financing
Understanding the Debt Capital Structure
The Debt Capital Structure
Overview:
- Debt financing comes in multiple layers, each with different risk/return profiles
- Structure follows "seniority waterfall"—who gets paid first in distress matters
- Higher in capital structure = lower risk = lower return (and vice versa)
- Most transactions use multiple tranches to optimize cost of capital
The Debt Capital Structure
Senior Secured Debt
Lowest risk, first claim on assets
Second Lien Debt
Secured but subordinated
Unsecured Debt / Senior Notes
No collateral claim
The Debt Capital Structure
Subordinated Debt / Mezzanine
Higher risk, equity-like features
Equity
Highest risk, residual claims
The Debt Capital Structure
Key Principle:
Each layer prices according to its recovery prospects in bankruptcy—senior secured debt recovers most, equity recovers least
- Senior secured lenders have first claim on collateral (assets pledged as security)
- Unsecured creditors rank behind all secured debt but ahead of subordinated debt and equity
- Equity holders are last in line and only receive value after all debt is repaid
- This hierarchy determines pricing: lower risk = lower yield, higher risk = higher yield
Revolving Credit Facilities (Revolvers)
What is it?
- Committed line of credit that can be drawn, repaid, and re-drawn during the term
- Typically 3-5 year maturity with option to extend
- Borrower pays commitment fee on undrawn portion (0.25-0.50%)
- Acts as liquidity backstop and working capital financing
Revolving Credit Facilities (Revolvers)
Key characteristics:
- Senior secured with first lien on all assets
- Floating rate tied to SOFR (Secured Overnight Financing Rate)
- Usage-based pricing—only pay interest when drawn
- Covenants: Maintenance covenants tested quarterly (most restrictive)
Revolving Credit Facilities (Revolvers)
Typical uses:
- Working capital fluctuations (seasonal inventory, receivables)
- Short-term liquidity needs and operational flexibility
- Letter of credit issuance for trade finance
- Bridge financing until permanent capital is arranged
Pricing example: SOFR + 250-400 bps depending on leverage, plus 0.25-0.50% commitment fee
Term Loan A (TLA)
What is it?
- Amortizing senior secured term loan with scheduled principal repayments
- Typically 5-7 year maturity
- Held primarily by commercial banks
- Designed for strategic acquisitions and conservative capital structures
Term Loan A (TLA)
Key characteristics:
- Senior secured with pro-rata claim alongside revolver
- Amortizing: 5-15% annual principal payments (deleverages over time)
- Floating rate (SOFR + spread)
- Maintenance covenants: Tested quarterly, similar to revolver
Term Loan A (TLA)
Typical uses:
- Strategic acquisitions by investment-grade or near-investment-grade companies
- General corporate purposes and refinancing existing debt
- Companies that want to maintain strong credit profiles
Term Loan A (TLA)
Differentiator:
Conservative structure with steady deleveraging—banks comfortable because debt balance decreases predictably
Pricing example: SOFR + 150-300 bps depending on credit profile
Term Loan B (TLB) / Institutional Loans
What is it?
- Non-amortizing (or minimal amortization) term loan sold to institutional investors
- Typically 7-8 year maturity
- The workhorse of LBO financing—highest leverage layer
- Held by CLOs (Collateralized Loan Obligations), mutual funds, hedge funds
Term Loan B (TLB) / Institutional Loans
Key characteristics:
- Senior secured with first lien (pari passu with TLA/revolver if present)
- Minimal amortization: 1% per year or bullet repayment at maturity
- Floating rate (SOFR + spread)
- Incurrence covenants only: No quarterly maintenance tests—only triggered if specific actions taken
Term Loan B (TLB) / Institutional Loans
Typical uses:
- LBO financing (majority of debt stack in PE deals)
- Dividend recapitalizations (refinance to pay dividends to sponsors)
- High-leverage refinancings
Term Loan B (TLB) / Institutional Loans
Why institutional investors buy it:
- Higher yields than investment-grade bonds
- Floating rate protects against rising rates
- Senior secured = better recovery in default than unsecured bonds
- Liquid secondary market for trading positions
Pricing example: SOFR + 400-600 bps for B/B- credits
High-Yield Bonds / Senior Notes
What is it?
- Unsecured debt issued in public or private (144A) bond markets
- Typically 7-10 year maturity
- Fixed-rate coupon paid semi-annually
- No collateral claim on assets (subordinated to secured debt in bankruptcy)
High-Yield Bonds / Senior Notes
Key characteristics:
- Unsecured (behind all secured debt in recovery waterfall)
- Fixed rate (e.g., 6.5% coupon paid twice yearly)
- Callable: Issuer can refinance after 3-5 years (often at premium)
- Incurrence covenants: Similar to TLB—only tested when taking specific actions
High-Yield Bonds / Senior Notes
Typical uses:
- LBO financing alongside TLB (provides "cushion" below secured debt)
- Refinancing existing unsecured debt
- Funding acquisitions when secured lending capacity exhausted
- Companies with limited tangible assets to pledge (service businesses, tech)
High-Yield Bonds / Senior Notes
Trade-off:
- Higher cost than secured debt (7-10% yields for single-B credits)
- But flexible covenants and longer maturity provide operational freedom
- Fixed rate = predictable interest expense but no benefit if rates fall
Pricing example: 6.5-9.5% fixed coupon depending on rating (B to CCC)
Second Lien Debt
What is it?
- Secured debt with junior claim on same collateral as first lien debt
- Typically 8 year maturity (longer than TLB)
- Sits between senior secured and unsecured debt in capital structure
- Less common post-2008 (unitranche and high-yield often preferred)
Second Lien Debt
Key characteristics:
- Secured but subordinated to first lien holders on same collateral
- Higher yield than first lien (compensates for subordination)
- Typically minimal amortization or bullet repayment
- Incurrence covenants (less restrictive than first lien)
Second Lien Debt
Typical uses:
- LBO financing when first lien capacity is exhausted
- Refinancing existing second lien or subordinated debt
- Companies needing additional secured capacity without diluting first lien
Second Lien Debt
Why less common now:
- Unitranche structures combine first and second lien into single facility
- High-yield bonds often provide similar economics with more flexibility
- Market preference for simpler capital structures
Pricing example: SOFR + 600-900 bps (higher than TLB due to subordination)
Unitranche Debt
What is it?
- Single "tranche" combining first and second lien characteristics
- Provided by direct lenders (BDCs, credit funds) not traditional banks
- Typically 6-7 year maturity
- Increasingly popular for middle-market LBOs ($10-500M EBITDA companies)
Unitranche Debt
Key characteristics:
- First lien secured on all assets (simpler structure than separate first/second lien)
- Blended pricing: One rate averaging what first and second lien would cost separately
- Flexible structure: Can customize amortization, PIK options, equity kickers
- Incurrence covenants with one maintenance covenant (often just leverage test)
Unitranche Debt
Typical uses:
- Middle-market LBOs where speed and certainty matter
- Situations requiring flexible documentation and relationship lending
- Borrowers willing to pay premium for simplified one-lender structure
Unitranche Debt
Advantages over traditional senior/junior structure:
- Single negotiation (not coordinating banks + second lien investors)
- Faster execution (one credit committee, one set of documents)
- More flexible during operational issues (one lender to work with, not multiple constituencies)
- Higher leverage often available (6-7x vs 4-5x from banks)
Pricing example: SOFR + 550-750 bps all-in (blending what would be L+400 first lien + L+800 second lien)
Mezzanine Debt / Subordinated Notes
What is it?
- Unsecured subordinated debt with equity-like features
- Typically 8-10 year maturity
- Highest layer of debt before equity in capital structure
- Bridges gap between senior debt capacity and equity check size
Mezzanine Debt / Subordinated Notes
Key characteristics:
- Unsecured and subordinated to all other debt (lowest priority)
- PIK toggle option: Can pay interest in-kind (adding to principal) instead of cash during early years
- Equity kicker: Often includes warrants for 5-15% equity ownership
- Minimal covenants: Typically none—operates like quasi-equity
Mezzanine Debt / Subordinated Notes
Typical uses:
- Highly leveraged LBOs where debt capacity maximized
- Growth capital for companies not yet profitable (cash interest burden problematic)
- Recap transactions where sponsors extract value but preserve leverage headroom
- Distressed situations where senior lenders won't provide more capital
Mezzanine Debt / Subordinated Notes
Return profile:
- Current yield: 10-15% cash interest (or PIK)
- Equity upside: Warrants provide additional 3-8% IRR if exit successful
- Total return target: 15-20% IRR
Risk: Lowest recovery in bankruptcy (often zero after senior claims satisfied)
Bridge Loans
What is it?
- Short-term financing (typically 6-12 months, extendable to 2 years)
- Intended to be temporary until permanent financing is arranged
- Used when closing needs to happen before long-term debt is syndicated
- "Bridges" timing gap between transaction close and capital markets access
Bridge Loans
Key characteristics:
- Senior secured typically (same priority as permanent TLB)
- High cost: SOFR + 600-800 bps plus ticking fees (0.50-1.00% per quarter if not refinanced)
- Takeout commitment: Often comes with committed longer-term financing to refinance bridge
- Short maturity: Forces urgency to refinance into permanent capital
Bridge Loans
Typical uses:
- LBO closings where high-yield bond syndication not complete at close
- Strategic M&A where timing critical and permanent structure being finalized
- Acquisition financing during market volatility (bond markets closed temporarily)
Bridge Loans
Why not just wait for permanent financing:
- Competitive deal processes require certainty and speed
- Seller won't wait for 6-8 week syndication process
- Market windows close—better to close on bridge and refinance later
Economic reality: Expensive insurance policy—if not refinanced, costs escalate dramatically (ticking fees designed to force action)
Asset-Based Lending (ABL)
What is it?
- Revolving credit facility secured by specific current assets (not all enterprise assets)
- Borrowing base calculated from eligible receivables and inventory
- Availability fluctuates with working capital levels
- Administered by specialized lenders who monitor collateral closely
Asset-Based Lending (ABL)
Key characteristics:
- Secured by current assets only: Receivables (advance rates: 80-90%), inventory (40-60%)
- Borrowing base: Can only draw up to % of eligible collateral value
- Monthly/weekly reporting: Must provide detailed collateral reports (aging, dilution, inventory turns)
- Lower leverage: Typically 2-3x EBITDA but could be higher availability based on assets
Asset-Based Lending (ABL)
Typical uses:
- Companies with substantial working capital (retail, distribution, manufacturing)
- Cyclical businesses where EBITDA fluctuates but current assets more stable
- Distressed situations where cash flow unreliable but tangible assets exist
- Supplement to cash flow loans when additional liquidity needed
Asset-Based Lending (ABL)
Advantages:
- Available when cash flow loans won't work (losses, restructuring, turnarounds)
- Flexibility—availability grows as business grows inventory/receivables
- Often survives bankruptcy (lenders secured by liquid assets, keep lending through Chapter 11)
Pricing example: SOFR + 200-400 bps (cheaper than cash flow loans for similar risk—better collateral)
Payment-in-Kind (PIK) Features
What is it?
- Structural feature allowing borrower to pay interest by issuing more debt instead of cash
- "PIK toggle" gives borrower choice each period: pay cash or PIK
- Compounds over time—deferred interest accrues and itself bears interest
- Common in mezzanine, sometimes in high-yield bonds
Payment-in-Kind (PIK) Features
Key characteristics:
- Preserves cash: Borrower conserves cash during early years or weak periods
- Debt grows: Principal balance increases by amount of PIK'd interest
- Higher rate: PIK interest rate typically 100-200 bps higher than cash interest rate
- Maturity wall risk: Large balloon payment at maturity if heavily PIK'd
Payment-in-Kind (PIK) Features
Typical uses:
- Growth companies that are cash flow negative or breakeven
- LBOs of cyclical businesses (PIK during downturns, cash during upturns)
- Highly leveraged deals where initial cash interest burden too heavy
- Distressed exchanges (amend-and-extend transactions to avoid default)
Payment-in-Kind (PIK) Features
Example:
- $10M mezzanine note at 12% cash / 14% PIK
- Year 1: Elect PIK → Owe $1.4M interest → Add to principal → New balance $11.4M
- Year 2: Elect PIK on $11.4M → Owe $1.596M → New balance $12.996M
- After 5 years of PIK: ~$19.3M owed (nearly doubled)
Lender perspective: Higher return but reinvestment risk—not receiving cash to redeploy
How to Choose the Right Debt Structure
Company characteristics:
- Asset intensity: Tangible assets → ABL possible; intangibles → cash flow lending
- Cash flow stability: Predictable → term loans; volatile → revolvers + conservative leverage
- Size: Large companies → bond markets; middle market → direct lenders; small → banks
How to Choose the Right Debt Structure
Transaction type:
- LBO: Maximize leverage → TLB + high-yield + mezzanine, aggressive structure
- Strategic M&A: Preserve flexibility → TLA + modest bonds, conservative structure
- Growth capital: Future-focused → Unitranche with PIK, flexible covenants
How to Choose the Right Debt Structure
Market conditions:
- Strong markets: Covenant-lite, higher leverage, tight spreads
- Weak markets: Maintenance covenants, lower leverage, wide spreads
- Rate environment: Rising rates favor floating (SOFR + spread); falling rates favor fixed (bonds)
How to Choose the Right Debt Structure
Cost vs. flexibility trade-off:
- Cheaper debt = more restrictions: Bank TLA with maintenance covenants, amortization
- Expensive debt = more freedom: Mezzanine/PIK with no covenants, long maturity
The optimal structure:
Balances cost of capital with operational flexibility needed to execute business plan
