# 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.

ALTSS-CREDIT-008

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](https://altss.com/glossary/mezzanine-debt)** 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](https://altss.com/glossary/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](https://altss.com/glossary/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](https://altss.com/glossary/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.
