You want to acquire a company or take over a business, but bank borrowing plus your own funds falls slightly short. Mezzanine is one option for filling that gap.

Mezzanine financing sits between ordinary loans and common equity.In exchange for lower recovery priority, providers receive higher interest or dividends and sometimes participate in share-price appreciation. Its defining feature is the ability to tailor burdens and returns between capital providers and recipients.

However, viewing it merely as convenient money covering what banks will not lend is risky. The number of parties to pay may increase without any change in the cash generated by the business. Together with our article explaining leverage, let us examine the financing structure.

1. Mezzanine is the “middle floor” of financing

“Mezzanine” means an intermediate floor in a building. In finance, it refers to capital between senior loans and common equity. The Development Bank of Japan's (DBJ) explanation lists subordinated loans, subordinated bonds, and preferred shares as examples.

This is a simplified comparison within one financing structure. Subordinated loans and preferred shares have different legal forms and rank relative to one another. Actual recovery priority depends on security, preferential claims, the borrowing entity, and contractual terms.

“Subordinated” does not mean the counterparty is inferior.It means allowing higher-ranking claims to be paid first when funds are insufficient, taking a later place in recovery.Thus, even when financing the same business, different layers incur losses in a different order.

2. Subordinated loans and preferred shares are similar, but different

A subordinated loan is debt; preferred shares are equity. The former carries contractual interest and repayment provisions; the latter has rights to dividends and residual assets under the articles and related terms. Preferred shares do not guarantee principal or dividends like a bank deposit.

DBJ describes preferred shares as receiving dividends and residual assets before common shares, while subordinated loans rank below other claims. Warrants or rights to convert into common shares may also be combined with them.

Adding mezzanine does not necessarily increase accounting equity.Contractual characteristics, accounting classification, and the equity credit assigned by banks or rating agencies must be considered separately.

For example, Tokyo Century's May 2024 presentation shows hybrid bonds treated as accounting liabilities while receiving partial equity credit for ratings. This describes that product, not a rule that all subordinated loans receive the same proportion of equity treatment.

3. Filling a JPY200 million gap in a JPY1 billion acquisition

Suppose an acquisition requires JPY1 billion. If JPY600 million is available as a senior loan and the buyer contributes JPY200 million in common equity, the shortfall is JPY200 million. Adding a JPY200 million subordinated mezzanine loan brings total funding to JPY1 billion.

JPY600 million senior debt + JPY200 million mezzanine + JPY200 million common equity = JPY1 billion

Canada's development bank BDC also presents mezzanine as a way to bridge the gap between the acquisition price and other financing. In exchange for higher costs than ordinary lending, repayment terms may be tailored to business cash flow.

However, acquiring a JPY1 billion company with JPY200 million of equity does not ensure success. The acquired business must pay interest on both loans, fund necessary capital expenditure and working capital, and ultimately repay the debt.

This approach also appears in PE-funded LBOs and business succession where a successor acquires shares. Sumitomo Mitsui Banking Corporation and DBJ's 2007 announcement expanding a mezzanine fund cited uses including M&A, business succession, and going private. This is not merely a new financial buzzword.

4. Who loses first? Comparing recoveries

Using the previous financing structure, compare the cash ultimately available for distribution. Exclude interest, taxes, and costs, and assume only JPY600 million of senior principal, JPY200 million of subordinated principal, and JPY200 million of common equity.

Common equity absorbs losses first, followed by mezzanine and then senior debt. If only JPY700 million remains, senior debt can recover all principal while mezzanine loses half its principal.

Conversely, even if JPY1.2 billion remains, a subordinated loan without equity participation still recovers only JPY200 million of principal, plus separately agreed interest and similar amounts.Priority over shareholders comes at the cost of less upside than shareholders receive. This asymmetry is the starting point for pricing mezzanine.

5. Look beyond interest rates: PIK, fees, and warrants

Mezzanine cost cannot be measured solely by annual cash interest. It may combine origination fees, additional payments at maturity or early repayment, and rights to acquire shares.

PIK: Adding interest to debt rather than paying it in cash

PIK (Payment in Kind) interest may be added to principal instead of paid in cash. The IMF's 2024 Global Financial Stability Report also notes that this supports near-term liquidity but increases the burden if performance does not recover.

For example, JPY200 million at 8% annually, entirely PIK and compounded annually for 5 years, grows to approximately JPY293.87 million. Zero cash interest does not eliminate the approximately JPY93.87 million cost. The question is whether exit proceeds or refinancing can cover the increased balance.

Warrants and similar rights: Including future equity value in compensation

Attaching warrants or similar rights lets capital providers potentially benefit from equity appreciation as well as interest. For borrowers, lower immediate cash payments may mean later dilution of common shareholders. Mezzanine does not guarantee freedom from dilution.

Instead of comparing quoted annual rates alone, comparehow much cash and equity value the contract transfersby the expected sale or repayment date. The 8% used here is an illustrative calculation, not a market benchmark or standard rate.

6. Being repaid later does not mean staying out of management

Because recovery ranks lower, providers may impose conditions on use of funds, additional borrowing, dividends, and asset sales. Even without voting rights, contractual consent rights and financial covenants can restrict management decisions. The same IMF report also describes private credit terms concerning leverage ratios, interest coverage, and restrictions on additional debt and dividends.

Check more than the number of years until repayment. Can interest be paid in ordinary circumstances? Are payments blocked if senior debt service encounters problems? Does early repayment incur costs? Whose consent is required after a covenant breach? Read loan agreements and intercreditor arrangements together.

Security and repayment priority are also different. Not every unsecured loan is mezzanine, and security does not guarantee full recovery. The recovery route also differs depending on whether the borrower is the operating company or a separate holding company.

7. Real estate mezzanine also starts with property value

Real estate acquisitions may also combine senior debt, mezzanine, and equity. Published materials from Star Asia Investment Corporation include examples of investing in mezzanine loan claims separately from real estate itself.

If a JPY1 billion property is acquired with JPY600 million senior debt, JPY200 million mezzanine, and JPY200 million equity, total loan principal equals 80% of the property price. However, being able to borrow 80% does not establish safety. If the property realizes only JPY700 million, half the mezzanine is lost in the simplified model above. Actual transactions also involve selling costs and unpaid interest.

During ownership, check what remains after rent covers operating expenses, senior principal and interest, and mezzanine payments. A thinner common-equity layer may increase equity returns but leaves less capacity to absorb vacancies, repairs, and rising interest rates.

8. Best suited to businesses that can explain their funding gap

Mezzanine is easier to consider where acquisitions or growth investment offer future earnings and ordinary debt and equity alone are difficult to arrange. Timing adjustments can also be useful, such as delaying repayment while post-acquisition integration costs arise.

However, adding debt does not solve persistent operating losses with no prospect of repayment. Additional common equity, a revised acquisition price, or postponed investment may be needed.

Providers should not select it solely for high yields either. They accept principal loss risk, deferred cash receipts, limited resale liquidity, and contractual complexity. Beyond assessing the target's value, they must determine whether that value will actually reach them through recovery.

Mezzanine bridges debt and equity while deciding who absorbs losses and how much.Use it not merely to maximize funding, but to align business cash generation with how long capital providers can wait. This supports sustainable financing.
