2.1 Mezzanine and second lien

PC101 3.1 placed two kinds of junior debt in the capital stack: second lien loans, secured but behind the first lien, and mezzanine debt, usually unsecured and below all secured debt. This lesson looks at them as investment strategies. Both sit between senior loans and equity, earn more than senior debt, and lose money sooner when a company struggles.

Some credit managers run dedicated mezzanine or junior capital funds; others hold junior positions inside broader opportunistic funds. Analysts need to know how these instruments earn their return and where the risk lies. LP-side analysts need to tell cash yield from PIK and equity upside when comparing funds. Investor relations and product teams, and service providers such as administrators and valuation agents, deal with PIK accruals and warrant values that don't show up in a simple interest calculation.

Where they sit

Recall Northfield Components, the fictional industrial parts maker from PC101 3.1:

Layer	Amount ($m)	Security
First lien term loan	200	First-priority lien
Second lien term loan	75	Lien on the same collateral, ranked second
Mezzanine debt	50	Unsecured, subordinated
Preferred equity	25	None
Common equity (sponsor)	150	None

When Northfield was sold for $260m, the first lien recovered 100%, the second lien 80% and the mezzanine nothing. The junior layers are where losses land first once the equity is gone.

Second lien: secured, but second

A second lien loan shares the first lien's collateral, but an intercreditor agreement says the first lien is repaid in full from that collateral before the second lien gets anything. The second lien is still secured. If the collateral is worth more than the first lien, the second lien has a real claim on the excess, ahead of any unsecured creditors.

Second lien loans commonly:

• pay floating-rate cash interest at a higher spread than the first lien, as in lesson 1.2's illustrative stack (first lien at SOFR + 450 bps, second lien at SOFR + 800 bps);
• have a similar or slightly longer maturity than the first lien;
• give the second lien lender limited rights to act in a default until the first lien has been dealt with, as set out in the intercreditor agreement.

Unitranche loans have replaced many second lien loans in the middle market (lesson 1.2), but second lien still appears, especially in larger deals.

Mezzanine: subordinated, with more ways to earn

Mezzanine debt usually has no lien. It's subordinated: the mezzanine lender agrees by contract to be repaid only after the senior debt. It commonly has a longer maturity than the senior loans, often with no principal due until the end.

Because it takes more risk, mezzanine earns its return in several ways:

• Cash interest, often at a fixed rate rather than floating.
• PIK interest, added to the loan balance and paid at maturity (PC101 3.2). This eases the borrower's cash burden but defers the lender's return.
• Warrants or an equity co-invest: rights to buy shares, or a direct equity stake alongside the sponsor, which give the lender a share of the upside if the company does well.
• Call protection and fees, which reward the lender if the loan is repaid early.

A worked mezzanine return

The following example is illustrative.

Hollin Bay Capital's opportunistic fund lends $30m of mezzanine debt to a sponsor-backed company for 5 years. It pays 12% cash interest plus 2% PIK, compounding annually. The PIK is added to the balance, and cash interest is charged on the growing balance.

Year	Opening balance	Cash interest (12%)	PIK added (2%)	Closing balance	Cash to lender
1	$30.000m	$3.600m	$0.600m	$30.600m	$3.600m
2	$30.600m	$3.672m	$0.612m	$31.212m	$3.672m
3	$31.212m	$3.745m	$0.624m	$31.836m	$3.745m
4	$31.836m	$3.820m	$0.637m	$32.473m	$3.820m
5	$32.473m	$3.897m	$0.649m	$33.122m	$37.019m

In year 5 the lender receives the last cash interest of $3.897m plus the full balance of $33.122m, which includes all the accrued PIK.

IRR without warrants: 14.00%. That's the 12% cash rate plus the 2% PIK. Because the PIK compounds and the cash interest is charged on the growing balance, the whole 14% compounds like a single rate.

IRR with warrants: 15.42%. Suppose the lender also holds warrants that are worth $3m when the company is sold at the end of year 5. Adding $3m to the year-5 cash flow lifts the IRR to 15.42%.

Three things to notice:

• Much of the return arrives late. About $18.73m of cash interest is paid over five years, but $3.122m of PIK and the whole $3m of warrant value arrive only at exit. If the company fails before then, the lender loses the PIK as well as its principal.
• The warrants add less than they seem. $3m is 10% of the loan, but received only at the end of year 5 it adds about 1.4 percentage points a year to the IRR, not 2 or 10.
• Warrant value is uncertain. It depends entirely on the company's equity value at exit. In a weak outcome, the warrants can be worth nothing.

Why recoveries are lower and pricing higher

Junior lenders are paid only from what's left after the senior debt. That has three effects.

Recoveries are lower and more variable. In Northfield's $260m sale, the mezzanine got nothing. Had Northfield sold for $300m instead, $25m would have been left after the first and second lien, and the mezzanine would have recovered 50%. A small change in the company's value makes a large difference to a junior lender's recovery, from nothing to half to all of its claim. For a first lien lender, the same change made no difference.

Losses come sooner. The equity cushion below mezzanine is thinner than the cushion below the first lien, so a smaller fall in value reaches it.

Control is weaker. Intercreditor and subordination terms commonly limit what junior lenders can do in a default, such as enforcing on collateral or blocking a restructuring, until the senior lenders are dealt with. PC301 covers these terms.

This is why junior debt is priced higher. Using PC101 4.1's formula, loss rate ≈ default rate × (1 − recovery rate), a lower recovery raises the expected loss even if the default rate is the same. The higher spread, PIK and warrants have to pay for that. Lesson 6.1 compares expected losses across strategies.

Key terms

• Second lien: a loan secured by the same collateral as the first lien but ranked behind it.
• Intercreditor agreement: a contract between lender groups that sets their priority and rights.
• Mezzanine debt: junior debt, usually unsecured and subordinated, often with cash and PIK interest and sometimes warrants.
• Subordinated: agreed by contract to be repaid only after more senior debt.
• PIK interest: interest added to the loan balance instead of paid in cash, compounding until repayment.
• Warrant: a right to buy a company's shares at a set price, giving the lender a share of the upside.
• Equity co-invest: a direct equity stake a lender takes alongside the sponsor.

Key takeaways

• Second lien is secured but ranks behind the first lien; mezzanine is usually unsecured and subordinated to all secured debt.
• Mezzanine earns a return from cash interest, PIK and sometimes warrants or an equity co-invest.
• In the worked example, 12% cash plus 2% PIK returns 14.00%, and $3m of warrant value at exit lifts that to 15.42%.
• Much of a mezzanine return, the PIK and any equity upside, arrives only at exit.
• Junior lenders recover less and less predictably, so they need higher pricing to cover expected losses.
