Second Lien
Also called: second lien loan · 2L
A second-lien loan is senior debt secured on the same collateral as a first-lien loan but ranking behind it, so second-lien lenders are paid from collateral proceeds only after first-lien claims are satisfied.
The second-lien lender takes the same security package as the first-lien lender but agrees to stand behind it in line for whatever the collateral fetches. Unlike mezzanine or subordinated debt, a second-lien loan is not usually subordinated in right of payment. In a US bankruptcy, if the collateral does not cover it, the unpaid part is generally an unsecured claim that ranks alongside the company's other unsecured creditors.
How second lien ranks
The ranking comes from the intercreditor agreement between first- and second-lien lenders. It typically provides:
- Enforcement standstill. Second-lien lenders may not enforce on collateral for a set period while the first lien acts.
- Turnover. Collateral proceeds received out of order are passed to first-lien creditors.
- Lien release. Second liens are released when first-lien lenders sell collateral in an enforcement.
- Insolvency waivers. Second-lien lenders agree in advance not to oppose certain first-lien-approved steps, such as debtor-in-possession financing.
- Purchase option. Second-lien lenders may buy out the first-lien debt at par.
In US practice, a "silent second" is a second lien whose holders have waived by contract most of the rights they could otherwise exercise in a bankruptcy case. In a US bankruptcy case, a subordination agreement is enforceable to the same extent as under applicable nonbankruptcy law (11 U.S.C. 510(a)). The extent of the waivers is the main negotiation point.
Second lien vs mezzanine
Both sit below first-lien debt, but they rank in different ways:
- Second lien is subordinated only as to collateral. It keeps an equal right of payment and is usually a floating-rate cash-pay loan.
- Mezzanine is usually unsecured or third-ranking, subordinated in right of payment, often pays part of its interest as payment-in-kind (PIK), and sometimes carries warrants.
The difference matters most when there are material assets outside the collateral, as the example shows.
Terms and pricing
Second-lien loans pay a higher margin than first lien. They typically carry longer non-call or prepayment-premium periods (call protection), and covenants that are absent or set with a cushion to the first-lien tests. In sponsor deals, a second lien is often held by a single lender or a small club of credit funds.
Many such structures have been replaced by unitranche facilities. A unitranche combines the first- and second-lien layers into one first-lien loan; lenders can then split it internally through an agreement among lenders.
How LPs assess second-lien exposure
- Check the attachment point: first-lien leverage, which is where second-lien losses begin.
- Check the detachment point: total secured leverage.
- Read the intercreditor waivers, because they determine how much influence the second lien has in a restructuring.
- Expect wider recovery dispersion than for first lien. A small change in enterprise value at default can move a second-lien recovery from full to near zero.
Worked example
Illustrative lien subordination, not payment subordination
Assume a US Chapter 7 liquidation, ignoring costs and priority claims. At default the collateral is worth $300m. First-lien debt is $250m and second-lien debt is $100m. The second lien recovers $50m from collateral and has a $50m deficiency claim. The company also has $20m of assets outside the collateral package and $30m of unsecured trade claims. The deficiency claim is an unsecured claim (11 U.S.C. 506(a)(1)) and shares those $20m pro rata with the trade claims (section 726(a)(2) and (b)): 50/80 × $20m = $12.5m. The second-lien recovery is $62.5m, or 62.5%. Had the second-lien debt instead been subordinated in right of payment to all other creditors, the $20m would have gone first to the $30m of trade claims, and its recovery would have stopped at $50m, or 50%.
Examples are illustrative; figures are not market data.
Not the same as
- Mezzanine Debt: Mezzanine is usually subordinated in right of payment and unsecured. Second lien is subordinated only as to collateral.
- First-Out / Last-Out: A last-out tranche is junior by agreement among lenders inside one first-lien facility. Second lien is a separate facility with its own lien.
- Subordinated Debt: Subordinated debt yields priority in payment from all sources. Second lien yields only the shared collateral.
Common mistakes
- Calling second lien "subordinated debt" without qualification. It is lien-subordinated, not payment-subordinated.
- Ignoring the intercreditor waivers, which can leave a second-lien lender with little influence in a restructuring.
- Assuming the deficiency claim is worthless. Its value depends on unencumbered assets and on the other unsecured claims.
Edge cases
- A second-lien loan to a company with no assets outside the collateral behaves economically like payment-subordinated debt.
- Some "second-lien" notes in the bond market share collateral with first-lien loans under a separate collateral-trust or intercreditor arrangement; read the documents.
