A second-lien loan is a secured term loan that shares the same collateral package as the first-lien debt but sits behind it in lien priority. It gets paid from collateral proceeds after the first-lien is made whole and before unsecured creditors and equity. It is not mezzanine debt and it is not payment-subordinated paper. The subordination sits purely in lien priority.
Why it exists is straightforward. Sponsors want to maximize leverage without giving up control. First-lien lenders will accept a junior lien if intercreditor rules prevent the second-lien from disrupting enforcement or jumping the queue. Second-lien lenders accept lower control and lower expected recovery in exchange for a higher coupon. That is the bargain and it drives how these loans are structured, documented, and priced.
What a Second-Lien Loan Really Is
In practical terms, a second-lien loan funds like a standard term loan, takes the same guarantees and security as the first-lien, and relies on an intercreditor agreement to define rights in stress. The second-lien lender’s payoff depends on first-lien discipline and collateral value continuity. If the first-lien grows or leakage shrinks the collateral pool, the second-lien migrates backward and recoveries fall.
Market Backdrop and Recovery Math
Rates set the floor and the mood. By late 2024, three-month Term SOFR hovered near 5.35 percent and three-month Euribor near 3.93 percent. Higher bases push all-in coupons up and make every 100 basis points of rate volatility matter. In the United States, middle-market first-lien direct lending printed roughly low-teens all-in in Q3 2024. Across Europe, senior secured yields sat in low double digits, with second-lien in the mid-teens. Long-run recovery data frames the spread and the size discipline: first-lien term loans have historically averaged materially higher ultimate recoveries than second-lien, with the junior tranche often posting low-teens average recoveries over long windows.
The practical implication is simple. When pricing a second-lien loan, underwrite to recovery, not just default odds. If a portfolio of deals delivers mid-teens averages, the last dollar of junior secured debt behaves like equity on the way down. That reality should inform spread, OID, and call protection, and it should push lenders to diligence collateral leakage closely.
Capital Stack Patterns – US vs. Europe
Capital structure norms affect where second-lien debt slots and how much room it has to breathe.
United States: borrower-friendly stacking
- Working capital first: An ABL or cash-flow revolver often carries super-priority on receivables and inventory.
- First-lien term loan: Syndicated TLB or private credit, frequently covenant-lite with incurrence tests.
- Second-lien term loan: Junior by lien with limited independent enforcement rights.
- Optional juniors: Subordinated or holdco debt can sit below.
First-lien headroom is often set on total net leverage with generous EBITDA addbacks and equity cure capacity. That leaves space to add a second-lien earlier in the cycle.
Europe: super senior on top, tighter headroom
- Super senior RCF: Controls cash dominion and hedging, ranking above senior term debt.
- Senior secured term: LMA-style documents dominate even in private deals.
- Second-lien term: Sized later and smaller due to tighter leverage tests and a taller stack.
European underwriting leans on senior net leverage and fixed charge coverage. EBITDA adjustments tend to be narrower after recent scrutiny. The outcome is a smaller, later second-lien that is more remote in the waterfall, which reduces early cash draw risk but raises remoteness in stress.
Intercreditor Terms That Decide Control
Control lives in intercreditor agreements. The US and Europe reach similar rank outcomes through different mechanics.
United States: LSTA-influenced patterns
- Standstill: After first-lien acceleration, a 90-180 day standstill typically applies before junior collateral enforcement. Payment blockages are narrow and triggered by defined events. The standstill falls away if the first-lien waives the default or actively enforces.
- Waterfall: Collateral proceeds pay administrative costs, then the first-lien in full, then the second-lien. ABLs and hedge banks may have super-priority inside the first-lien via collateral trust provisions.
- Bankruptcy: First-lien lenders control adequate protection and section 363 sale direction. Second-lien turns over adequate protection that reduces first-lien collateral value and agrees to support a first-lien-led sale within set parameters. Priming DIPs are not opposed if they respect the lien order; the junior seeks junior adequate protection.
- Amendments: The second-lien cannot change collateral documents or releases in a way that binds the first-lien without first-lien consent.
Europe: English-law, trust-based architecture
- Security agent and trust: A security agent holds security on trust, with a ranking and priority of payments section and turnover clause ordering distributions. Parallel debt is used in certain civil law jurisdictions.
- Instructing group: A Senior Instructing Group directs enforcement. Juniors cannot instruct until a 90-180 day standstill expires, with the timeline calibrated by asset type.
- Restructuring plans: UK Part 26A Restructuring Plans allow cross-class cramdown if juniors are no worse off than the relevant alternative.
- Super senior priority: Super senior RCFs and hedging rank above the senior term. Second-lien sits below all senior secured claims.
Net effect: second-lien is behind on control in both regions. The US leans on Chapter 11 DIPs and section 363 sales, while English law provides a faster share pledge enforcement path and court-driven cramdowns. In tight valuations, active second-lien committees can influence outcomes, but they do not drive the bus.
Funding Mechanics and Cash Flows
Second-lien loans primarily fund at closing. Delayed draw tranches exist but are usually capped and tied to intercreditor conditions. Cash pay is standard. PIK toggles appear in pressured refinancings and often carry strict guardrails to avoid leakage.
Mandatory prepayments usually follow first-lien triggers but only pay down the second-lien after the senior is satisfied. Asset sale and insurance sweeps go to the seniors first. Some private deals include first-lien-only excess cash flow sweeps, so the second-lien relies on maturity or a takeout absent a refi.
Collateral coverage nominally mirrors the first-lien, but leakage is the real battleground. In the US, investment baskets and ratio builders can move assets like IP or receivables into unrestricted subsidiaries, shrinking the pool supporting both liens. Intercreditors rarely block leakage directly, so the fight sits in the first-lien credit agreement. Europe tends to hold firmer on topco shares and core cash accounts, and unrestricted subsidiaries are rarer. The bottom line is the same: diligence coverage and leakage more than headlines.
Docs Checklist and Negotiation Hotspots
Expect a full junior secured package that mirrors the senior with a separate collateral agent and a negotiated intercreditor. The friction points drive downside economics:
- Standstill mechanics: Shorter, certain, and with automatic fall-away if the first-lien sits on its hands is worth real spread.
- DIP and adequate protection: Secure a role, budget, and junior adequate protection, and limit turnover of benefits that are not strictly tied to priming.
- First-lien incremental: Cap pari growth or price the priming risk. Uncapped senior growth pushes juniors backward fast.
- Release authority: Seek vetoes or floors on collateral and guarantee releases in low-proceeds sales. A pure senior-only release right can whipsaw recovery.
Economics, Pricing, and Breakeven Math
Price second-lien in components: base rate, spread, OID, fees, call protection, and documentation risk. With higher bases, premiums matter more than headline coupons.
- United States: Second-lien spreads often run 200-350 bps over the first-lien, with 100-300 bps of OID based on size and risk. With first-lien all-in in the low teens in Q3 2024, second-lien for sponsor-backed middle-market issuers frequently lands in the mid-teens all-in.
- Europe: Second-lien coupons commonly sit in the mid-teens, supported by Euribor floors, OID, and step-ups.
Upfront fees of 1.5-3.0 percent are typical in the US. Call protection in syndicated junior loans often runs a 101 soft call for 6-12 months, while private placements can include make-wholes and stepped calls. European loans commonly set 101 for 12 months, and privately placed junior secured notes follow bond-style schedules.
Fresh angle – a fast breakeven test: assume a 3-year average life, mid-teens all-in yield, and a 15 percent downside recovery. If you expect a 20 percent cumulative default probability over 3 years, you need roughly 500-600 bps of annual excess return over a senior comp to justify the tail risk. If documentation leaves priming wide open or leakage unchecked, widen OID or reduce size until the breakeven clears your hurdle.
Sizing and Headroom – Simple Rules
Size to cash interest coverage that survives normalization, not just the sponsor case. In 2024-2025, many US private credit shops targeted 1.8x-2.2x recurring cash interest coverage at close for junior secured tranches. In Europe, super senior headroom and minimum liquidity often bind before pure coverage tests. Three quick checks help avoid re-trades:
- Rate sensitivity: Run plus or minus 100 bps on SOFR or Euribor. At a 5-handle base rate, that move can swing coverage meaningfully.
- EBITDA haircut: Apply a haircut for addbacks and leakage if unrestricted subsidiaries, non-guarantor baskets, or generous adjustments exist.
- Waterfall reality: In stress, super senior RCFs and hedges pay first. Adjust proceeds before assigning second-lien any value.
Accounting, Tax, and Regulatory Notes
Under US GAAP and IFRS, second-lien debt is usually held at amortized cost unless embedded derivatives require bifurcation. OID and fees accrete through the effective interest method. Reporting cadence usually tracks the first-lien with added junior-specific limits on restricted payments, liens, and junior debt incurrence.
Tax treatment is standard for secured loans. Non-US lenders may access the US portfolio interest exemption with proper paperwork. Interest limitation rules such as US section 163(j) and EU or UK ATAD can cap deductibility when coupons are higher. Hybrid mismatch rules rarely bite plain-vanilla junior secured loans, but fund vehicles and co-invest SPVs deserve a check. Regulated managers should align KYC or AML processes and sanctions controls with senior agent standards. Syndicated junior notes rely on private placement exemptions and transfer restrictions to QIBs or professional clients.
Real Risks and Edge Cases
- Priming or uptiering: First-lien open market exchanges or non-pro rata uptiers can push new money above you. The intercreditor rarely stops this. Control the risk in the first-lien docs or price it.
- Dropdowns: Transfers of IP, cash, or receivables into unrestricted subsidiaries melt second-lien value fast. Tighten baskets or assume more leakage in sizing.
- Release rights: Senior-only authority to release collateral and guarantees in low-proceeds sales can crater recovery. Seek de minimis proceeds floors and arm’s-length process checks.
- Venue dynamics: Chapter 11 turns on DIPs and section 363 sales plus turnover. UK Plans can cross-class cramdown with valuation support. Prepare valuation work early.
- Transfer limits: Overwide DQ lists suppress liquidity for the second-lien. Push for sunsets or reasonableness standards.
Portfolio tip: limit correlated junior exposure across the same sponsor or first-lien agent when first-lien docs share permissive incremental and leakage features. Priming risk clusters by sponsor playbook.
US vs. Europe – Practical Differences
- Enforcement: US processes rely on court-driven DIPs and sales. Europe blends share pledge enforcement with court-led cramdowns. First-lien makes the early call in both.
- Governance center: US governance sits in the first-lien credit agreement with the intercreditor enforcing rank and timing. Europe’s intercreditor is the playbook via SIG thresholds and standstills.
- Super senior height: Europe’s super senior RCF and hedging create a taller stack above second-lien. US ABL super-priority is common but not universal.
- Information flow: US syndicated formats limit junior access and consultation. European private deals allow more bespoke junior protections when you anchor the ticket.
Alternatives and When They Fit
- Second-out unitranche: Similar economics inside one facility governed by an agreement among lenders. Cleaner enforcement is a plus, though first-out versus second-out fights can still be sharp without a strong agent. See unitranche loans for structure and pricing.
- Mezzanine or holdco PIK: Higher pricing and worse recoveries due to structural subordination. Useful when operating company security is constrained.
- Preferred equity: Faster and flexible for the borrower, but you trade away security and remedies.
If the trade tilts toward unitranche in your market, compare term dynamics across regions in US vs Europe unitranche analyses.
Execution Timeline You Can Actually Hit
A repeat sponsor second-lien can close in 4-6 weeks on a tested playbook:
- Weeks 1-2: Align term sheet with first-lien capacity and intercreditor guardrails across sponsor, first-lien agent, junior lead, and counsel.
- Weeks 2-4: Negotiate intercreditor standstill, DIP language, turnover, release authority, and senior incremental caps.
- Weeks 2-4: Map collateral and diligence leakage paths, engaging local counsel as needed.
- Weeks 3-5: Document credit agreement and security, settle conditions precedent, perfect liens, and obtain opinions.
- Weeks 5-6: Coordinate funding with senior draws and any takeouts.
Decision Screens That Improve Returns
- Coverage first: Size to recurring cash interest coverage after a conservative EBITDA haircut and a plus 100 bps rate stress. Check minimum liquidity, including committed RCF availability, post-close.
- Cap senior growth: Secure hard caps on first-lien incremental or widen OID if not available.
- Standstill certainty: Lock a 90-120 day period with automatic fall-away if the first-lien does not act or waives the default.
- Release protections: Tie collateral releases to arm’s-length sales or confirmed plans with a proceeds floor for junior consent.
- European fit: For smaller, later juniors, see European second-lien deals and calibrate size to super senior headroom.
Conclusion
Second-lien is a tool for extending leverage while keeping sponsor control intact, but its value lives in the intercreditor and the first-lien document set, not in the marketing deck. Underwrite like an owner on the downside: treat the last dollar as equity-sensitive, insist on real intercreditor caps and standstill discipline, and size to stressed cash coverage after leakage. If documents leave priming and releases wide open, you are underwriting sponsor behavior more than collateral, so price, protect, or pass. For broader market context on origination and enforcement norms, complementary reads on direct lending in private credit and intercreditor agreements and lien subordination can help sharpen your playbook.
