When a capitalization requires more proceeds than a senior lender will advance and a sponsor would prefer not to sell additional common equity, the gap is often filled with mezzanine debt or preferred equity. The two are frequently discussed as interchangeable, and in economic summary they can look similar: a fixed or accruing return, a position senior to common equity, and limited participation in residual upside. The distinctions that matter in a workout, however, are structural, and they are decided when the documents are drafted.
What follows describes structures as they are commonly encountered. Terms vary substantially among transactions, lenders and capital providers. The characterization of any particular investment — together with its priority, the remedies available to each party, and how it is treated in a workout or an insolvency proceeding — depends on the transaction structure, the governing documents and applicable law. It is not determined by the label the parties put on it.
Position in the capital stack
Both instruments occupy the space between the senior mortgage loan and the sponsor’s common equity. A mezzanine loan is typically made to the entity that owns the property-owning borrower — the mezzanine borrower is the parent, not the property owner. Preferred equity is typically an equity investment made into the property owner or into a holding company above it, admitting the capital provider as a member or partner with a preferred return and priority distribution rights.
That difference — lending to the owner of the borrower versus investing into the ownership structure — drives most of what follows.
Debt and equity characteristics
Mezzanine debt is generally documented as a loan: a note, a loan agreement, a pledge, and the covenants and events of default that accompany secured lending. It carries a stated interest rate, a maturity date, and an unconditional obligation to repay. Preferred equity is generally documented in the operating or partnership agreement, or in an amendment to it, and takes the form of a priority return and a priority right to distributions rather than an unconditional promise of repayment.
The distinction is not always clean. Preferred equity can be structured with mandatory redemption dates, accruing returns and remedies that make it function much like debt, and some instruments described as preferred equity are close to debt in substance. Whether a given instrument is treated as debt or equity for tax, bankruptcy, accounting or regulatory purposes is a fact-specific question that should be analyzed on its own terms rather than assumed from the label.
Collateral and structural differences
A mezzanine lender is typically secured by a pledge of the equity interests in the property-owning borrower. It does not hold a mortgage on the real property, and it does not have a lien on the asset itself. Its collateral is the ownership interest one level up.
A preferred equity investor generally holds no lien at all. Its protection comes from the governance and economic provisions of the operating agreement — priority distributions, consent rights over major decisions, and rights that expand upon defined trigger events. In some transactions a preferred investor also holds a pledge of the common member’s interests, which moves the structure closer to mezzanine debt in practical effect.
Remedies and control rights
The remedy sets differ meaningfully, and this is often the reason a senior lender prefers one structure over the other.
- A mezzanine lender’s principal remedy is typically a foreclosure on the pledged equity under Article 9 of the Uniform Commercial Code. A UCC sale can generally be conducted on a considerably shorter timeline than a mortgage foreclosure, and the purchaser takes the equity subject to the existing senior mortgage debt.
- A preferred equity investor’s remedies are ordinarily contractual and governance-based. On a triggering event these commonly include removal of the common member as managing member, assumption of control over major decisions, forced sale or refinancing rights, and an increase in the accrual rate.
- Both structures frequently include guaranties from the sponsor covering defined conduct, and those guaranties often mirror the recourse carve-outs found in the senior loan.
- In each case, the practical value of a remedy depends on how quickly it can be exercised and what consents are required to exercise it.
Intercreditor and recognition issues
Neither structure operates in isolation from the senior lender. Where mezzanine debt is used, the relationship is ordinarily governed by an intercreditor agreement between the senior lender and the mezzanine lender. Where preferred equity is used, the senior lender’s requirements typically appear in a recognition agreement, or in the senior loan documents themselves.
These agreements address a recurring set of questions: whether and when the subordinate party may exercise remedies; what notice and cure rights it has with respect to senior loan defaults; whether it may purchase the senior loan and on what terms; who is an acceptable transferee following a change of control; whether replacement guarantors must be delivered and who qualifies; and how the senior lender’s transfer covenants and single-purpose entity requirements apply to a change at the subordinate level. Negotiating these points late in a transaction is a common source of delay, because the senior lender’s approval is required and its credit and legal review runs on its own timeline.
Return structures
Mezzanine debt commonly carries a stated rate, sometimes with a portion paid currently and a portion accruing, and may include exit fees, minimum multiple provisions or prepayment protection. Preferred equity commonly carries a preferred return that may be paid currently to the extent of available cash flow and otherwise accrue and compound, together with a redemption obligation and, in some structures, limited participation in residual proceeds.
Because a preferred return is generally payable from available cash flow rather than as an unconditional obligation, the accrual and compounding mechanics, and the consequences of failing to redeem by a target date, warrant close attention. Two instruments quoted at similar rates can produce very different outcomes depending on how unpaid amounts accrue and what happens when a redemption date passes.
Senior lender considerations
Senior lenders are not indifferent to what sits above them in the ownership structure. Their concerns commonly include the identity and qualifications of any party that could take control of the borrower, the continuity of the single-purpose entity and separateness covenants, the effect of a change of control on existing guaranties, and whether the subordinate party’s remedies could disrupt the operation of the property or the servicing of the senior loan. Some senior lenders and securitization programs will accommodate one structure more readily than the other, and some will require that any subordinate capital be documented in a specified form. These constraints are worth identifying before the subordinate capital is priced.
When each structure may be considered
The selection is usually driven by a combination of senior lender requirements, the capital provider’s own mandate and preferences, tax and accounting considerations for both sides, and the speed and certainty of the remedies each party expects to need. Some capital providers are organized to hold debt and not equity, or the reverse. Some senior loan documents permit one and prohibit the other. In transactions where the senior lender will not permit a pledge of the borrower’s equity, preferred equity may be the only structure available; where a capital provider requires the speed of a UCC remedy, mezzanine debt may be preferred.
A practical takeaway
Preferred equity and mezzanine debt are best evaluated on their documents rather than on their labels. The economic summary in a term sheet rarely reveals the differences that determine what happens if the asset underperforms. The provisions worth reading closely are the collateral, the trigger events, the remedy timeline, the treatment of accrued and unpaid amounts, and the senior lender’s intercreditor or recognition requirements — because those, rather than the stated rate, describe what each party actually holds.
