Debt and Credit Markets

The acquisition debt stack as a stack: senior secured, unitranche and first-out/last-out, second lien and mezzanine, seller paper, SBA 7(a), covenants and SOFR-era pricing, leverage metrics, and the inter-lender agreements that decide who gets paid first.

Who this is for

You are assembling or underwriting the debt behind an acquisition, and the number you commit to has to survive a credit committee and a downside case.

How is acquisition debt structured, and what sits where in the stack?

Acquisition debt is a stack ordered by who gets paid when cash runs short: senior secured facilities first, then unitranche debt split into first-out and last-out tranches, then second lien and mezzanine, then seller paper. Intercreditor agreements rather than the instrument names decide the actual payment order, and covenants decide when that order stops being hypothetical.1,2,3

Most published treatments of leveraged finance are a list of instruments. A deal is not a list of instruments; it is one structure in which each piece is priced against the others and an intercreditor document decides what happens when it goes wrong. This hub is organized as a stack — instrument, pricing, covenant, and inter-lender position — and it is kept current, because the single most checkable weakness in the competitive corpus is that it is not.

Straight answers

Is the 6x leverage guidance still in effect?

No — the OCC and the FDIC rescinded the 2013 Interagency Guidance on Leveraged Lending on 5 December 2025. The guidance had identified total debt above 6.0x EBITDA as raising supervisory concern for most industries, and the 2014 implementation FAQs were already explicit that 6.0x was not a bright-line test. Two points survive the rescission: the Federal Reserve did not join the withdrawal, and a lender's own credit policy is what actually constrains a given deal. As of 30 July 2026 this is the current position.

Is the borrower a party to the AAL?

Typically no — the borrower is usually not a party to the Agreement Among Lenders. The AAL sits between the lenders in a unitranche facility and allocates the interest and fee skim between first-out and last-out tranches, enforcement direction rights, protective-advance caps, additional-debt limits, amendment voting by tranche, and the events that shift the waterfall. The borrower signs one credit agreement at a blended rate and does not see the split.

Sources: T3-05 · T2-07

What's the difference between an AAL and an intercreditor agreement?

An intercreditor agreement governs relations between separate facilities with different lien or payment priorities; an AAL governs relations inside a single unitranche facility that the borrower experiences as one loan. The distinction matters at enforcement: with an intercreditor, the borrower has two agreements and two sets of remedies; with an AAL, it has one, and the tranche fight happens without it.

How much equity injection does an SBA 7(a) acquisition loan require?

SOP 50 10 8, effective 1 June 2025, requires a minimum 10% equity injection on a full change of ownership. A seller note may count toward that injection only if it is on full standby, and only up to half of the required injection — so a 10% requirement can be met with 5% cash and a 5% standby seller note, not with a standby note alone. This is what closed the zero-down SBA acquisition window.

Can you still buy a business with no money down using an SBA loan?

No. SOP 50 10 8 reinstated a minimum 10% equity injection on a full change of ownership, which ends the zero-down structure that circulated in the prior window. Half of the injection can come from a seller note on full standby; the rest is real equity.

What is SOFR and what does a SOFR rate mean?

SOFR is the Secured Overnight Financing Rate published by the Federal Reserve Bank of New York, and it is the floating-rate base for essentially all US leveraged loans after the LIBOR transition. Because it is an overnight secured rate rather than a term unsecured one, loan documents reference it through a term or averaged convention with a spread adjustment, and the day-count and averaging conventions are set by the publisher rather than by the lender.

What is a debt service coverage ratio and what do lenders require?

DSCR measures cash available for debt service against required debt service over a period, and it is the sizing constraint that binds in acquisition lending at the lower end of the market — more often than a leverage multiple does. SBA-backed acquisition lending under SOP 50 10 8 is underwritten on coverage, which is why an SBA-financed buyer's maximum price falls out of a coverage test rather than a comparable multiple.

Cornerstone answers

Each block below opens a cornerstone page in one of this hub's pillars: the passage, the takeaways, and — where a figure is published — the row-by-row provenance and confidence tier behind it.

Credit agreement covenants that matter in a downturn

In a downturn, three features of a credit agreement decide what happens: whether the financial covenants are maintenance-tested or incurrence-tested, how EBITDA is defined inside the agreement rather than in the model, and who has the right to act on a default. Maintenance covenants are tested every quarter regardless of activity, so they trip first. Incurrence covenants only bind when the borrower takes an action, which means a declining business can breach nothing until it needs something.

  • Ask which covenants can be tripped by the business simply getting worse. Maintenance tests bite automatically; incurrence tests only bind when you want to do something.
  • Covenant-lite usually means no maintenance test on the term loan plus a springing test on the revolver — which can put the revolver lender in the only seat with live leverage.
  • The EBITDA definition inside the agreement gives or takes more headroom than the ratio level does. Read it together with the compliance certificate.
  • Coverage tests catch amortization that leverage tests ignore. An amortizing facility has less room to absorb an earnings decline than a bullet at the same multiple.
  • The excess cash flow sweep decides whether a recovery deleverages the lender or funds your plan.
  • Payment blockage and standstill live between the lenders, not in your credit agreement. In a unitranche you may not even be a party to the agreement that governs enforcement against you.
  • The six-times leverage figure is historical supervisory framing. The OCC and FDIC rescinded the 2013 guidance on 5 December 2025 — source current capacity to dated market data instead.

Unitranche vs senior and mezzanine: how the stack gets chosen

A unitranche is a single blended facility that replaces a separate senior and subordinated structure, priced between the two and usually sliced internally into first-out and last-out tranches. A senior-plus-mezzanine structure keeps them separate: cheaper senior money, then subordinated debt carrying warrants. The choice turns on how many lender relationships you want to manage, how much certainty you need at close, and which provider is willing to underwrite your business at all.

  • Order any capital structure by waterfall position first, then ask who provides each layer. The provider decides your covenants, your diligence burden and your workout behaviour.
  • A unitranche does not remove complexity; it moves it into an agreement among lenders that the borrower is typically not a party to.
  • An agreement among lenders sits inside one facility. An intercreditor agreement sits between separate facilities. They are not interchangeable.
  • Where the structure is a single-lender unitranche plus a super-priority revolver, the revolver sits ahead of the unitranche in the waterfall.
  • The mezzanine warrant closes the gap between the coupon a borrower can service and the return the lender needs. Negotiating the coupon alone rarely moves the total.
  • Lenders count preferred equity as equity and mezzanine as debt for leverage purposes — which is frequently the entire reason one is chosen over the other.
  • Under a government-guaranteed small-business acquisition loan, a seller note counts toward the required equity injection only on full standby for the life of the loan and only for at most half the injection.

The stack, ordered by waterfall position Rows are ordered by position in the payment waterfall, which is the graph's ordering for the debt-capital-structure pillar — not by prevalence, popularity, or cost. Columns are the five attributes that define an instrument in this taxonomy, including the provider column the competitive corpus omits. Confidence is 'primary' where a fetched source states the attribute, 'structural' where the row is taxonomy synthesis from the node graph.

Method The instrument table is ordered by waterfall position, not by cost, prevalence or preference, and the ordering comes from the graph rather than from editorial judgement. Each row states the confidence level and the sources behind its attributes.

Debt capacity: sizing leverage for an acquisition

Debt capacity for an acquisition is sized two ways, and the two do not agree. A leverage-multiple approach applies a multiple to adjusted EBITDA and is the cash-flow lending convention. A coverage approach asks whether cash available for debt service covers the required payments with a cushion, and it is what actually governs small acquisition loans, asset-based facilities and government-guaranteed structures. The two produce different answers on the same business, and the binding one is whichever your lender uses.

  • Two sizing methods exist and they disagree systematically. Multiple-based sizing ignores everything below EBITDA; coverage-based sizing is what small acquisition loans actually run on.
  • Capital-intensive and working-capital-hungry businesses support less debt than their EBITDA multiple implies. The gap is the cash costs the multiple ignores.
  • Negotiate the EBITDA definition, not just the multiple. It governs every covenant test for the life of the facility and decides whether add-ons can be given pro-forma effect.
  • Ask which lender types will look at this business before asking what leverage the market supports. Each type underwrites to a different constraint.
  • Build the sources-and-uses table before the letter of intent. It is the arithmetic that decides whether the price is fundable at all.
  • Under the small-business operating procedures effective 1 June 2025, a complete change of ownership needs a ten per cent minimum equity injection, and a standby seller note can fund at most half of it.
  • Model the personal guaranty and the residence lien as real terms, not as paperwork. They change the risk of the transaction, not only its cost.
  • Ability to pay is a bid ceiling, not a value. And six times total debt to EBITDA is historical supervisory framing — the guidance behind it was rescinded on 5 December 2025.

Method The worked example compares two sizing methods on identical inputs to isolate the difference between them. It asserts no multiple, cushion or advance rate, because the dossier establishes none, and directs current market levels to dated datasets with their vintage attached.
