Every layer in a holding chain must answer a question the layer above cannot.

The chain between a fund and its asset is drawn as a column of boxes, and the column grows. A holding company for the treaty. A second for the lender, who wants a clean company to take security over. A third because the state the asset sits in requires a domestic holder of a particular category. A fourth because counsel in the fourth jurisdiction suggested a blocker for a characteristic nobody has since been able to name. A fifth because the co-investor wanted its own entry point. By the time the asset is bought there are five entities between the fund and it, each with a board, an audit, a filing calendar, a bank account and a substance requirement, and nobody in the room can say what two of them are for. The chain was drawn by accretion, one adviser at a time, and nobody read it as a whole, because reading it as a whole is nobody's job unless the manager makes it somebody's.

This note sets out the test every layer must pass, the five functions a layer can legitimately serve and how each is evidenced, what a layer costs to run, what a layer binds at exit and in the middle years, why chains grow and who grows them, how a chain is read as a whole, the shortest chain for a land platform and for a cross-border position, a comparison, a worked chain as a type, cases, what each party holds, the sequence, questions, terms and what to read.

The test

For each layer, name the question it answers that the layer above it cannot. The question is asked of every layer, including the ones that seem obvious, and it is asked in writing, because a function that cannot be written down is not a function.

If the answer is a treaty, name the treaty and the article, and confirm with the tax adviser, in the adviser's own name, that the layer's substance will be enough for the treaty to apply and that the layer's purpose would survive the principal-purpose test most treaties now carry. If the answer is a lender, name the security the lender takes at that layer and why it cannot take it one layer up: a clean company with no other creditors, a jurisdiction whose registry records the pledge, an enforcement route the lender's counsel has used. If the answer is a holder category, name the state's rule and the category the layer satisfies, and confirm with counsel in the state that the registry will record the layer as that category. If the answer is ring-fencing, name the liability being fenced and the law that makes the fence hold. If the answer is a co-investor's or a parallel's entry point, name the agreement that requires it. If there is no answer, the layer is a cost with no function, and it is removed before it is formed.

The test is asked again whenever anything changes. A treaty renegotiated, a lender refinanced out, a state's ownership law amended, a co-investor bought out, and a layer that answered a question last year may answer none this year.

The five functions

A treaty function. The layer is resident in a jurisdiction whose treaty with the asset's state reduces withholding on dividends or interest, or removes the asset state's tax on a gain. The function is evidenced by the adviser's opinion and by the substance the opinion is conditional on: resident directors, meetings, decisions, beneficial ownership of what the layer receives, and a purpose beyond the treaty.

A security function. The layer is the company over which the lender takes its security, chosen because it is clean, because its jurisdiction's registry records the security and because the enforcement route is known. The function is evidenced by the facility and the security documents, and by the lender's counsel's confirmation that the layer is where the security should sit.

A category function. The layer is the person the asset's state permits to hold the asset: a Saudi vehicle within the 2025 law's categories, a Qatari company in a named area, a Kuwaiti licensed scheme, an Indian construction-development company. The function is evidenced by the state's instrument and counsel's confirmation of the registry's practice.

A ring-fencing function. The layer separates one asset's liabilities from another's: one company per parcel, so that a parcel's encumbrances, consents and lender do not reach the next. The function is evidenced by the separation itself and by the absence of cross-guarantees.

A structural function. The layer is where a co-investor, a parallel vehicle or a joint venture partner enters, because the agreement between them requires a company they both hold. The function is evidenced by the shareholders' agreement.

A layer may serve two functions, and the best chains have layers that do. A layer that serves none is removed.

What a layer costs to run

The cost is in the running rather than the formation. Directors who must actually meet, in the jurisdiction, with a quorum resident there and papers read there. Accounts prepared by somebody who is present, audited, and filed on the jurisdiction's calendar. A registered office, a corporate services provider, a bank account whose opening takes a quarter and whose maintenance requires the provenance file to be refreshed annually. A substance requirement that in both centres and in most onshore states is tested by a regulator or a tax authority with the power to look through. Tax filings in the layer's jurisdiction. And the legal cost of every amendment above or below that reaches the layer.

A layer that fails the substance test does worse than nothing. It is the layer the authority looks through, and the look-through reaches the structure above it: the treaty position claimed at that layer is lost, the residence asserted there is denied, and the facts found there are evidence about the layers beside it. A chain of five with substance at none is a drawing.

What a layer binds

Every layer is a consent at exit. A sale of the asset, a sale of the holding company, a distribution in kind and a refinancing each pass through each layer's board, each layer's lender and, where the layer is in a state that regulates it, each layer's regulator. A chain of five is five sets of board minutes, up to five lender consents and up to five regulatory notifications for one transaction. An exit that was planned for a chain of two has been planned for a different structure.

A layer also binds the middle years. A refinancing at the asset level that would have needed one lender's consent needs every layer's board to approve the new security. A co-investor admitted beneath a layer needs a shareholders' agreement at that layer. A change of manager reaches every layer's management agreement. A change in a layer's own jurisdiction's law, a new substance rule, a new filing, reaches the chain.

Substance, layer by layer

Substance at a layer means the layer actually does what a company in its jurisdiction does. Resident directors who are not the manager's employees, or not only them, with a quorum the manager's people cannot make alone. Board meetings held in the jurisdiction, with papers circulated before, deliberation minuted, conflicts recorded and decisions taken rather than ratified. A registered office and a corporate services provider with staff present. A bank account operated from the jurisdiction. Accounts prepared and audited there. Contracts in the layer's own name, signed by its own directors on its own resolutions. For a treaty layer, the retention of what it receives and a board decision to distribute, so that it is the beneficial owner rather than a conduit. For a category layer, the compliance with the state's conditions on the category, the registration and the filings.

Each of those is a line in the layer's row of the table, with a party who produces it and an annual cost, and a layer whose row is blank in the substance column is a layer that will be looked through. The structure paper names the corporate services provider for each layer, the directors, the meeting calendar, and the budget, because substance is a budget line before it is a fact.

The minute book as the chain's evidence

The minute book of each layer is the evidence that the layer existed in fact and not only on paper, and it is read by every party that tests the chain. The tax authority reads it for residence and beneficial ownership: did the board decide, where, on what papers. The lender's counsel reads it for authority: did the board validly approve the security, within its powers, with a quorum. The buyer's counsel reads it for validity: was every acquisition, financing and disposal approved by the right body. The regulator reads it for substance. A minute book that shows an annual circular resolution approving accounts shows a layer that decided nothing, and every party that reads it reaches the same conclusion.

The minute book that holds shows, for each decision the chain required, a meeting in the jurisdiction, the papers, the directors present, the deliberation, the conflicts declared, the decision and the authority. It is kept by the corporate services provider under an agreement that names what it must contain, and it is reviewed annually by the manager's compliance function against the table.

Where it surfaces

At the refinancing, when every layer's board must approve the new security and three have not met since formation.

At the source state's inquiry, when the treaty layer's minutes show it was managed from the manager's office.

At exit, when the buyer's counsel asks the function of a layer and nobody can answer.

At the regulator's substance review, when a centre company's presence is tested against the facts.

At the distribution in kind, when the asset must pass up through five boards, each of which must resolve.

The cost of getting it wrong

A chain formed by accretion costs, over ten years, the running cost of every layer it did not need, which for two unnecessary layers is two boards, two audits, two offices and two substance budgets for a decade. It costs the positions lost at the layers nobody staffed: a treaty benefit denied, a residence relocated, a security questioned. It costs the exit: a buyer's discount for layers it must take and diligence, and the delay while each layer's consents are obtained. And it costs the middle years: every refinancing, admission and change reaching five boards instead of three. The reading of the chain as a whole costs a week before any layer is formed.

Why chains grow

Chains grow because each adviser solves its own problem with a company. The tax adviser adds the treaty layer. The lender's counsel adds the security layer. Counsel in the asset's state adds the domestic holder. The co-investor's counsel adds the joint entry. Each addition is correct for its purpose and nobody is responsible for the whole, because nobody is paid for the whole. The manager, who bears the cost of the whole, sees the chain only when it is drawn, and by then each layer has an adviser who will defend it.

The cure is a single reading of the chain before any layer is formed, by the party responsible for the structure, asking the test of each layer with every adviser's answer in one document. The reading collapses layers that serve the same function, removes layers that serve none, and produces a chain whose every entity has a stated function, a stated cost and a stated consent at exit.

Reading a chain as a whole

The reading produces a table: one row per layer, with its jurisdiction, its function, the instrument that evidences the function, the adviser who stands behind it, its annual running cost, its substance requirement and the party who produces it, and its consent at each exit route. A row with an empty function column is removed. Two rows with the same function are collapsed. A row whose substance requirement has no party named is a layer nobody will run. The table is the chain, and the drawing is its illustration.

The shortest chain for a land platform

A land platform's chain is three layers because three questions need answering. One company per parcel, seated in the parcel's state in the permitted category, ring-fencing title, encumbrances, consents and the parcel's lender, and sold alone when the exit is parcel by parcel. A portfolio holder above the parcel companies, consolidating, carrying the concentration limits, and sold whole when the exit is the portfolio; seated in a centre or onshore as the lender, the acquirer and the tax adviser can each read. The platform itself, holding the register. A fourth layer appears only where a treaty, a lender or a co-investor requires it, and it is named as such.

The shortest chain for a cross-border position

A fund's position in an operating company in a Gulf state is usually two layers below the fund: a holding company in the fund's centre or in a treaty jurisdiction, serving the treaty function and the security function together, and the domestic company the state's category requires, serving the category function. A blocker is added only where a characteristic must be blocked and the adviser has named it. A chain longer than three below the fund is read twice.

A timeline, as a type

Month one: the asset is identified; the tax adviser, the lender's counsel, counsel in the asset's state and the co-investor's counsel each propose a layer. Month two: the chain is read as a whole; the table is produced; two layers are collapsed and one removed; the advisers confirm their functions on the shortened chain. Month three: the layers are formed with their providers, directors and meeting calendars named; the substance budget is approved. Month four: the acquisition, approved at each layer's board in the jurisdiction, minuted. Year two: the refinancing; three boards approve the new security on papers, within a month. Year four: the asset state's ownership law changes; the table is re-read; the domestic holder's category is confirmed as still required. Year six: exit; the buyer's counsel reads three minute books and the table, and prices the chain at no discount.

The structure paper's page

The structure paper's chain page is the table, with a column added for the exit routes and a row for each layer's consent on each. Beneath it, the substance budget by layer and year. Beneath that, the advisers' confirmations, each signed for its own layer. The page is the answer to the buyer's counsel, the lender's counsel, the regulator and the tax authority, and it is the document the manager's successor reads in year six to learn what the chain is for. It is prepared once, before formation, and updated on every change, and a chain without it is a chain whose functions live in five advisers' heads.

Collapsing a layer that exists

A layer found to serve no function after formation is collapsed, and the collapse is itself a transaction: a transfer of the layer's asset, the shares of the layer below, to the layer above, with the registry's recording, the lender's consent where the layer carries security, the tax adviser's reading of the transfer in the layer's jurisdiction and the layer's liquidation under its own law. It costs less than ten years of running the layer and more than not having formed it. The structure paper carries the collapse as a step with a date where the reading finds a layer to remove, and the cheapest collapse is the one done before the asset is bought.

The parallel and the feeder as layers

A parallel vehicle beside the fund, and a feeder above it, are layers in the same sense and pass the same test. The parallel answers a question the main fund cannot: a holder whose tax, regulatory or domicile position requires a separate vehicle. The feeder answers a question the master cannot: a holder who must hold through a vehicle in a particular place. Each has a function, a cost and a consent at exit, and each is read on the table beside the chain beneath. A parallel formed for a holder who could have been admitted to the main fund, or a feeder formed for convenience, is a layer without a function and is removed before it is formed.

The chain and the register

The register reads the chain too, before it subscribes. An institutional holder's counsel asks for the structure chart and, increasingly, for the function of each layer, because the holder's own tax position depends on the chain's and the holder's own regulator asks about the vehicles its money passes through. A chain the manager can explain in a table is a chain the holder's counsel can clear in a week; one the manager explains as "what counsel advised" is a chain the holder's counsel diligences itself, at the manager's cost in time.

A chain, as a type

A fund holds an operating company in a Gulf state. The first draft of the chain has five layers: a centre company, a treaty company in a third jurisdiction, a blocker in a fourth, a domestic holder, and a co-investment company between the treaty company and the blocker. The reading asks the test of each. The centre company serves the fund's own residence and the lender's security; it stays. The treaty company's treaty is the same one the centre's state has with the asset state; the layer is collapsed into the centre company, which takes the treaty function with the substance it already has. The blocker's characteristic cannot be named by anyone; it is removed. The domestic holder is the category; it stays. The co-investment company is required by the co-investor's agreement; it stays, and the co-investor enters at the centre company instead, which the agreement is amended to permit. The chain is three: the centre company with treaty, security and co-investment functions; the domestic holder with the category; and the operating company. Two boards, two audits and two substance requirements are removed before they are formed, and the exit test runs through three consents rather than five.

Four cases, as types

A fund holds an operating company in a Gulf state through four companies: a centre company for the fund's own reasons, a treaty company in a third jurisdiction, a blocker in a fourth, and a domestic holder. At exit the buyer's counsel asks the function of the blocker, and nobody can answer; the buyer prices it as a company it must take and diligence, and the treaty company's substance, on inspection, consists of a circular resolution a year, so the treaty position is lost in the same diligence.

A fund holds a parcel of land through one company per parcel, a portfolio holder in a centre and the platform itself. Each layer has a stated function: the parcel companies ring-fence title and security, the portfolio holder carries the concentration limits and is the thing sold when the exit is the portfolio whole, the platform holds the register. The chain is three because three questions needed answering, and the buyer at exit reads a table rather than a drawing.

A fund's chain is read again in year four after the source state amends its ownership law. The domestic holder is now a category the state no longer requires, and the layer is collapsed before the exit rather than explained at it, with the lender's consent obtained on the same reading.

A fund forms a chain by accretion, with each adviser's layer, and runs it for six years with substance at two of five layers. At the refinancing in year six every board must approve the new security; three boards have not met since formation; the lender's counsel finds the chain cannot validly grant what the lender asks, and the refinancing is delayed by two quarters while the chain is re-papered.

What each party holds

The manager holds the reading of the chain as a whole, the table, and the decision to form each layer.

Each adviser holds the function its layer serves and the opinion or document that evidences it.

The lender holds the security function and the layer it sits at.

Counsel in the asset's state holds the category function and the registry's practice.

The directors of each layer hold its substance and its minutes.

The buyer at exit holds the table, which it prices, or the drawing, which it discounts.

The sequence

1. The chain is drawn with a function, a cost and a consent at exit stated beside every layer, before any layer is formed.
2. Every layer without a stated function is removed, and layers with the same function are collapsed.
3. Each remaining function is tested with the adviser whose opinion or document it relies on.
4. The substance each layer must produce is named with the party who produces it and the annual cost.
5. The exit test is run through every layer, so that the consents at exit are known before the asset is bought.
6. The test is re-run on any change in treaty, lender, ownership law, co-investor or manager.

Questions a manager asks

Is a short chain always better. A chain is as long as its functions require and no longer; a chain of four with four functions is right, and a chain of two with one function is one too long.

Can a layer serve two functions. The best ones do: a centre company that is resident for the treaty and clean for the lender; a parcel company that is the category and the ring-fence. Collapsing layers onto shared functions is where most of the saving is.

What if two advisers disagree about a layer. Then the layer's function is in dispute, and the manager decides on the written answers, because the manager pays for the layer.

How often is the chain re-read. On every change that reaches it, and at least annually, because substance is produced every year or not at all.

Does the buyer at exit really read the chain. Its counsel reads every layer's function, minute book and consents, and prices what it finds; a table answers in a day, a drawing in a quarter.

What about a layer the register requires. A holder that requires its own entry point has required a structural function, and the layer serves it; the cost is the holder's to understand.

Terms used

Layer: a company in the chain between the fund and the asset.

Function: the question a layer answers that the layer above cannot: treaty, security, category, ring-fencing or structural.

Substance: the facts, directors, meetings, decisions, records, that make a layer what it claims to be.

Look-through: an authority's treatment of a layer as transparent for want of substance or purpose.

Consent at exit: the approval a layer's board, lender or regulator must give to an exit route.

The table: the reading of the chain as a whole, one row per layer, which replaces the drawing.

What to read

The tax adviser's opinion and its conditions; the lender's security requirements by layer; each state's ownership and registry rules; each jurisdiction's substance requirements; the shareholders' agreements that require structural layers.
