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%**.

It typically provides:","- **Enforcement standstill.** Second-lien lenders may not enforce on collateral for a set period while the first lien acts.\n- **Turnover.** Collateral proceeds received out of order are passed to first-lien creditors.\n- **Lien release.** Second liens are released when first-lien lenders sell collateral in an enforcement.\n- **Insolvency waivers.** Second-lien lenders agree in advance not to oppose certain first-lien-approved steps, such as debtor-in-possession financing.\n- **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."]},{"heading":"Second lien vs mezzanine","paragraphs":["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.\n- **[Mezzanine](/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."]},{"heading":"Terms and pricing","paragraphs":["Second-lien loans pay a higher margin than first lien. They typically carry longer non-call or prepayment-premium periods ([call protection](/glossary/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deals, a second lien is often held by a single lender or a small club of credit funds.","Many such structures have been replaced by [unitranche](/glossary/unitranche) facilities.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](/glossary/first-out-last-out)."]},{"heading":"How LPs assess second-lien exposure","paragraphs":["- Check the attachment point: first-lien leverage, which is where second-lien losses begin.\n- Check the detachment point: total secured leverage.\n- Read the intercreditor waivers, because they determine how much influence the second lien has in a restructuring.\n- Expect wider recovery dispersion than for first lien.
