What are senior secured notes?
Senior secured notes are bonds that combine two protections at once. Senior means they rank ahead of subordinated and unsecured debt in repayment priority. Secured means they are backed by a lien on specific collateral — often the same assets pledged to the company's loans. Together, those features make them the safest debt a company issues in the bond market.
They sit alongside or just behind a borrower's bank loans in the capital structure. In a leveraged financing, a sponsor often funds an acquisition with a mix of secured term loans and senior secured notes, then layers riskier unsecured or subordinated bonds beneath them.
Because they carry the strongest claim, senior secured notes pay the lowest coupon of any bond a given issuer offers. Investors accept less yield in exchange for collateral backing and priority — the inverse of high-yield notes lower in the stack.
Where they sit and how they behave
Priority is the whole point. In a default, claims are paid top-down, and senior secured noteholders sit near the top.
- Collateral first. If the company defaults, secured creditors are repaid from the proceeds of the pledged collateral before any unsecured claim sees a dollar.
- Lien ranking. Notes can be first-lien (first claim on the collateral) or second-lien (behind the first-lien debt but still ahead of unsecured). First-lien notes are safer and price tighter.
- Intercreditor terms. An intercreditor agreement governs how secured lenders and noteholders share collateral, enforce rights, and split recoveries.
- Fixed coupon, bullet maturity. Like most bonds, they typically pay a fixed coupon and repay principal in a single bullet at maturity, rather than amortizing.
Why issuers use them
Senior secured notes let a borrower raise long-dated, fixed-rate debt at a lower coupon than it would pay on unsecured bonds, because the collateral and priority reduce the lender's risk. For a sponsor, that means cheaper financing for the secured tranche and a fixed cost that does not float with SOFR.
The trade-off is encumbrance: pledging collateral to the notes limits what is available to secure future borrowing, and the indenture's covenants constrain additional debt, liens, and asset sales. Issuers weigh the lower coupon against the flexibility they give up by tying up collateral.
