What is the difference between first lien and second lien?

Both hold security over the same assets. The first lien is repaid in full from those assets before the second lien receives anything, and an intercreditor agreement usually stops the second-lien lenders from enforcing or contesting the first lien's sale for a period. Because the second lien takes losses before the first lien does, it is priced higher. In leverage terms, first-lien leverage counts only the first-lien debt; a second-lien lender reads total leverage down to and including its own loan.

Is second-lien debt secured?

Yes. A second-lien loan has a charge over the borrower's assets, usually the same assets as the first lien, but it ranks behind. In a recovery it is paid from what the security realises after the first lien is repaid, and ahead of unsecured creditors and, usually, mezzanine lenders. If the assets fetch less than the first-lien debt, the security yields nothing and the second-lien lender claims for the shortfall as an unsecured creditor, though many European intercreditor agreements make it hand what it receives to the first-lien lenders until they are paid.

What is a standstill period in a second-lien loan?

It is a period after a default during which the second-lien lenders agree not to enforce their security, so that the first-lien lenders can decide whether to waive, restructure or sell. The length is negotiated and differs by deal and market. A standstill commonly ends early if the first-lien lenders start enforcing themselves or the borrower enters an insolvency process, and the second-lien lenders may then act only within what the intercreditor agreement allows.

Why would a borrower choose a second-lien loan over mezzanine?

Usually because it is cheaper. Security reduces the lender's expected loss, so a second-lien loan is priced below mezzanine and typically pays cash interest without warrants that dilute the owners. It costs the borrower a heavier burden on its assets and a second secured creditor to negotiate with in a downturn. A mezzanine loan may suit a borrower whose cash flow cannot carry cash interest, because its interest can often be capitalised.

Second-Lien Loan: a Worked Example

Same security, second in line, first to lose.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED 2026-11-07 · 6 MIN READ

// THE SHORT ANSWER

A second-lien lender holds a charge over exactly what the senior lenders hold, and agrees to take nothing from it until they are repaid. That makes its loan a thin, exposed slice: it is secured, so it ranks ahead of every unsecured creditor and any mezzanine lender behind it, but a modest fall in the business's value can leave it with nothing while the first lien recovers in full. A credit reader on either side of the line therefore reads the same numbers differently. The first-lien lender sees a cushion; the second-lien lender sees how little value stands between it and a total loss.

PART OF What Your Bank Holds as Security

// 01 — WHY A LENDER TAKES SECOND PLACE

A buyer that needs more debt than the senior lenders will provide has three common ways to fill the gap: more equity, an unsecured or mezzanine loan behind the senior, or a second-lien loan secured on the same assets. The second lien is usually the cheapest of the junior options for the borrower because its lender has security, and the most acceptable to the senior lenders because their claim on that security comes first.

The second-lien lender accepts its place because security still matters in the outcomes that are not a total loss. If the business is sold for more than the first-lien debt, the surplus goes to the second lien before any unsecured creditor, mezzanine lender or shareholder sees it. Its price sits above first-lien debt and below mezzanine, which is roughly where that risk falls.

// 02 — HOW THE RANKING IS MADE

The ranking is set by contract. Without one, priority between two charges over the same assets would turn on each market's default rules, such as the order of registration under the New Zealand and Australian personal property securities regimes, which need not match the deal. An intercreditor agreement between the two lender groups and the borrower sets the order in which enforcement proceeds are applied, and commonly adds three restrictions on the second-lien lenders: they may not enforce for a standstill period after a default unless the first lien has started enforcing; they may not challenge the first lien's security or its conduct of a sale; and they must release their security when the first lien sells the assets in an enforcement, so that a buyer takes them clean.

The form differs by market. In UK and European deals the two classes usually share one security package held by a security trustee, and the intercreditor agreement often subordinates the second lien's payments as well as its security, with payment blocks after a senior default. US deals more often give the second lien its own security documents and collateral agent, and the agreement subordinates the liens without subordinating the right to be paid. In New Zealand and Australia, where personal property securities legislation lets a secured party agree to rank behind another (section 70 of New Zealand's Act, section 61 of Australia's), the order is set by a deed of priority or an intercreditor agreement, recorded where needed against the registrations.

// 03 — THE EXAMPLE

A sponsor-backed provider of security alarm monitoring, constructed for this page like every figure in it, earns EBITDA of US$30m from monitoring contracts. Its operating company owes US$110m on a first-lien term loan and drawn revolver at a margin of 4.25%, and US$40m on a second-lien loan at 7.50%. Both are secured on all its assets under one intercreditor agreement. The margins and amounts are the example's.

First-lien leverage: 110 ÷ 30 = 3.67×

Total leverage: 150 ÷ 30 = 5.00×

Value after costs First lien Second lien

US$160m 110 of 110 100% 40 of 40 100%

US$135m 110 of 110 100% 25 of 40 63%

US$100m 100 of 110 91% 0 of 40 0%

Between the first and third rows the value falls by US$60m. The first-lien lenders lose US$10m of it, or 9% of their claim; the second-lien lender loses all US$40m. That asymmetry is the second lien's risk in one table, and it is why the second-lien lender reads its exposure on the slice between 3.67 and 5.00 times EBITDA rather than on the business as a whole. At a value of US$135m its security returns US$25m; had the loan been unsecured, it would have shared that sum with the operating company's suppliers and other unsecured creditors. The table leaves out claims such as some employee entitlements and, in the UK, the share of floating-charge realisations set aside for unsecured creditors, which in each market can come ahead of parts of a lender's security.

// 04 — HOW IT DIFFERS FROM MEZZANINE

Mezzanine finance usually ranks behind second-lien debt. It is often unsecured or holds only a junior share pledge, is subordinated in payment so its interest stops when the senior is in default, and is priced higher, often with payment-in-kind interest or warrants over the equity. A second-lien loan, by contrast, generally pays cash interest and holds a charge over the operating assets.

The distinction is narrower in UK and European deals, where second-lien payments are often subordinated too, and wider in US deals, where the second lien's claim to be paid usually ranks equally with the first lien's and only its claim on the collateral comes second. A reader who sees the label should open the intercreditor agreement before assuming which kind of junior debt it is.

// 05 — WHERE IT DECIDES A FILE

For the first-lien lender, the second lien is a cushion of loss-absorbing debt beneath it, but also a second creditor with a seat at every restructuring. Its file reads the standstill period, the release mechanics and how much new first-lien debt the agreement lets the borrower add ahead of the second lien. Each of those decides whether the first lien can sell the business quickly when it must.

For the second-lien lender, the reading is a valuation question. It asks what the business is worth in a forced sale, not on the sponsor's multiple, and how much headroom above the first-lien debt that leaves. A second-lien loan sized against a buyout price can find, in a weak year, that its whole claim sits above the value of the business while it waits out a standstill it agreed to.

What is the difference between first lien and second lien?: Both hold security over the same assets. The first lien is repaid in full from those assets before the second lien receives anything, and an intercreditor agreement usually stops the second-lien lenders from enforcing or contesting the first lien's sale for a period. Because the second lien takes losses before the first lien does, it is priced higher.

Is second-lien debt secured?: Yes. A second-lien loan has a charge over the borrower's assets, usually the same assets as the first lien, but it ranks behind. In a recovery it is paid from what the security realises after the first lien is repaid, and ahead of unsecured creditors and, usually, mezzanine lenders. If the assets fetch less than the first-lien debt, the security yields nothing and the second-lien lender claims for the shortfall as an unsecured creditor, though many European intercreditor agreements make it hand what it receives to the first-lien lenders until they are paid.
What is a standstill period in a second-lien loan?: It is a period after a default during which the second-lien lenders agree not to enforce their security, so that the first-lien lenders can decide whether to waive, restructure or sell.

It costs the borrower a heavier burden on its assets and a second secured creditor to negotiate with in a downturn. A mezzanine loan may suit a borrower whose cash flow cannot carry cash interest, because its interest can often be capitalised.
