Structure
HoldCo vs OpCo debt
OpCo debt sits at the company that owns the assets and earns the cash. HoldCo debt sits one level above it, behind every creditor of the trading business, and is repaid only from what the trading company is permitted to pay up.
Also called structural subordination · holdco debt · opco debt · upstream guarantee · holdco PIK
Structural subordination is measured in company law, not in a contract. Distance from the assets is the risk.
| Claim | Position |
|---|---|
| OpCo trade creditors | At the assets |
| OpCo secured debt | Direct security |
| OpCo junior debt | Same company |
| HoldCo debt | One level up |
| Shareholders | Furthest |
General position under a typical UK group structure. Not legal advice; the position depends on the group and the documents.
Where each sits
OpCo is the operating company: the entity that owns the assets, employs the people, holds the contracts and earns the cash. HoldCo is the company that owns the shares in OpCo, usually with no trading operations of its own.
OpCo debt is lent to the trading company. It has direct claims against the business, and where it is secured it holds a debenture over the assets themselves. HoldCo debt is lent one level up, to a company whose only meaningful asset is a shareholding.
That difference is not a matter of contractual ranking. It is a consequence of company law: a creditor of the parent has no claim against the subsidiary's assets, and shareholders rank behind creditors on a winding up. HoldCo debt is therefore behind every OpCo creditor, including trade creditors, by structure rather than by agreement.
What structural subordination means
Contractual subordination is an agreement between creditors of the same company about who is paid first. Structural subordination needs no agreement at all: it follows from where the debt sits in the group.
If OpCo is wound up, its assets pay its own creditors. Only what remains after every OpCo creditor is satisfied, including trade creditors and the tax authority, flows up to HoldCo as a shareholder distribution. A HoldCo lender is therefore recovering out of residual equity value, which is a materially different proposition from lending against the assets.
The practical consequence is that HoldCo debt is riskier than junior OpCo debt even where the junior OpCo debt is contractually subordinated. The junior OpCo lender is at least in the queue at the company that owns things. The HoldCo lender is not in that queue at all.
Cash has to be allowed up before it can service HoldCo debt. Four separate things can stop it.
| Constraint | How often it binds |
|---|---|
| Tax on the distribution | Plannable |
| Directors' duties | 20–42 on the scale |
| Distributable reserves | Law, not cash |
| Permitted payment basket | Usually binds |

Upstream guarantees, and why they exist
The obvious way to close the gap is for OpCo to guarantee the HoldCo debt, and to grant security. That converts a structurally subordinated claim into a direct one.
This is why upstream guarantees appear so often in group financings, and why an OpCo senior lender resists them so firmly. A guarantee from the trading company puts the HoldCo lender into the same queue as the senior lender, which is precisely what the senior lender priced against.
Where upstream guarantees are given, they usually come with limitations: capped at an amount, subordinated in right of payment to the senior debt, and constrained by corporate benefit requirements, since the directors of OpCo must be able to justify giving a guarantee for a debt that benefits its parent rather than itself. In practice at £3-15m the senior lender's permitted-debt provisions frequently prohibit them outright.
Dividend trickle-up
Absent a guarantee, the HoldCo lender is repaid only from cash that OpCo is permitted to pay upward. That path has four separate gates, and any one of them can close it.
Distributable reserves must exist. This is a company law test on accumulated realised profits, not on cash: a company with money in the bank and no distributable reserves cannot lawfully pay a dividend. A business that has made losses, or that carries a large amortisation charge from an acquisition, can be cash-generative and reserve-poor at the same time.
The directors must be able to justify the payment consistently with their duties. The distribution must fall within the permitted payments basket in the OpCo facility, and no payment blockage arising from a default may be in force. And the payment carries whatever tax consequences the structure produces.
Of the four, the permitted payments basket is the one that most often binds, because it is sized by the senior lender at signing to a level that suits them rather than to whatever the HoldCo debt requires.
Why HoldCo debt is usually PIK
It follows directly from the trickle-up problem. A holding company with no trading operations has no cash of its own, so any cash coupon has to be funded by a distribution from OpCo, which depends on gates the HoldCo lender does not control.
Accruing the interest instead removes that dependency for the life of the facility. The balance compounds and the whole amount falls due at maturity or on exit, by which point either the business has been sold or a refinancing is being arranged, and cash is available from the transaction rather than from a quarterly distribution.
So HoldCo notes are commonly all-PIK rather than split cash-and-PIK, which is the more usual construction on OpCo mezzanine. The consequence for the borrower is that the amount repayable at exit is materially larger than the amount advanced, and it is paid out of enterprise value rather than trading cash.
The same £2m of EBITDA carries very different total leverage once a HoldCo layer is added on top.
| Structure | Total leverage |
|---|---|
| OpCo senior only (£6m) | 3x |
| Plus £1m HoldCo | 3.5x |
| Plus £2m HoldCo | 4x |

Why a structure uses one
Almost always to reach leverage the senior lender will not underwrite directly.
On a business with £2m of EBITDA, an OpCo senior facility of £6m is 3.0 times, comfortably inside the bank senior band. Adding £1m at HoldCo lifts aggregate leverage to 3.5 times, and £2m lifts it to 4.0 times, without the senior lender's own test moving at all. The senior lender is measuring its own debt against earnings; the HoldCo layer is invisible to that calculation unless the definitions capture it.
That is the appeal in a buyout where the equity cheque would otherwise be larger, and it is also the risk. Aggregate leverage of 4.0 times serviced partly by accruing debt is a more fragile structure than 4.0 times of unitranche, because the accretion continues regardless of performance and the exit has to clear the whole stack.
What the senior lender will insist on
An OpCo senior lender presented with a HoldCo layer above them will usually require several things, and a borrower should expect them rather than treat them as obstruction.
No upstream guarantee or security from OpCo. A subordination or intercreditor deed regulating what HoldCo may receive and when. A payment blockage suspending distributions while a senior default subsists. Confirmation that the HoldCo debt is non-cash-paying, or that any cash pay is inside the permitted payments basket. And frequently a requirement that the HoldCo debt matures after the senior debt, so the senior facility is not refinanced under pressure from a junior maturity.
That last point is worth checking specifically. A HoldCo instrument maturing before the senior facility creates a moment where the group must refinance the junior layer while the senior lender holds all the cards, which is a poor position by construction.
What a borrower should check
Five things, and they are all in the documents rather than the term sheet.
Whether the OpCo facility's leverage definition captures the HoldCo debt. If it does, the HoldCo layer consumes senior covenant headroom and the structure is tighter than it appears. If it does not, the senior test is measured on senior debt alone and the aggregate position sits outside the covenant.
The size of the permitted payments basket and whether it is sufficient to service any cash element. The relative maturities. Whether accrued PIK at HoldCo counts as debt anywhere in the OpCo covenant. And what happens on a sale: whether the HoldCo debt is repayable from proceeds ahead of shareholders and on what terms.
The last one is where the economics land. HoldCo debt is repaid out of enterprise value, so every pound of accreted balance is a pound less of equity proceeds, and the accretion runs for the whole hold whether or not the business performs.
Common questions
What is the difference between HoldCo and OpCo debt?
OpCo debt is lent to the trading company that owns the assets and earns the cash, with direct claims against the business. HoldCo debt is lent to the parent whose only meaningful asset is a shareholding in OpCo, so it has no direct claim on the assets at all.
What does structural subordination mean?
That a claim ranks behind another because of where it sits in the group, not because of any agreement. A creditor of the parent has no claim against the subsidiary's assets, and shareholders rank behind creditors on a winding up, so HoldCo debt sits behind every OpCo creditor including trade creditors by structure alone.
Is HoldCo debt riskier than junior OpCo debt?
Generally yes, even where the OpCo junior debt is contractually subordinated. The junior OpCo lender is at least in the queue at the company that owns the assets. The HoldCo lender is not in that queue at all, and recovers only from residual value flowing up as a shareholder distribution.
What is an upstream guarantee?
A guarantee given by the trading company for debt borrowed by its parent, which converts a structurally subordinated claim into a direct one. Senior lenders resist them firmly because they put the HoldCo lender into the same queue the senior lender priced against, and at £3-15m the permitted-debt provisions often prohibit them outright.
Why is HoldCo debt usually PIK?
Because a holding company with no trading operations has no cash of its own. A cash coupon would have to be funded by a distribution from OpCo, which depends on distributable reserves, directors' duties, the permitted payments basket and any payment blockage. Accruing the interest removes that dependency until maturity or exit.
What stops cash moving up to the HoldCo?
Four gates. Distributable reserves must exist, which is a company law test on accumulated profits rather than on cash. The directors must justify the payment. It must fall inside the OpCo facility's permitted payments basket with no payment blockage in force. And it carries whatever tax the structure produces. The permitted payments basket is the one that most often binds.
Why would a structure use a HoldCo layer at all?
To reach leverage the senior lender will not underwrite directly. On £2m of EBITDA, £6m of OpCo senior is 3.0 times; adding £2m at HoldCo takes aggregate leverage to 4.0 times without the senior lender's own test moving. That reduces the equity cheque, and it makes the structure more fragile because the accretion continues regardless of performance.
What should I check in a HoldCo structure?
Whether the OpCo leverage definition captures the HoldCo debt, the size of the permitted payments basket, the relative maturities — the HoldCo debt should mature after the senior facility, not before — whether accrued PIK counts as debt in the OpCo covenant, and how the HoldCo debt is repaid on a sale, since every pound of accreted balance is a pound less of equity proceeds.
