Layering means putting distance between an owner and an asset by inserting companies. Each company is lawfully registered, each is individually explicable, and each one adds a separate legal process to anyone trying to establish who is at the end of the chain.
The technique is not about any single company being secret. It is about the cost of following the chain. Establishing the ownership of a company in one jurisdiction may take a day. Establishing it through five companies in four jurisdictions, two of which require a formal mutual legal assistance request, can take years — and the structure can be rearranged faster than the requests can be answered.
How it works
The FATF and Egmont Group study of beneficial ownership concealment, built on an analysis of 106 case studies1 , finds that shell companies are the most common type of legal person used in schemes designed to obscure beneficial ownership2 , and that money may flow through multiple layers of shell companies before reaching its destination3 . (An earlier version of this page said the study identified layering as the most common concealment method; what it identifies is shell companies as the most common vehicle.)
Ownership is divided vertically. The operating company is owned by a holding company, which is owned by another holding company, which is owned by a trust or foundation, which is administered by a corporate trustee. At no point is the beneficial owner a registered shareholder of anything.
Ownership is also divided horizontally. Rather than one parent holding a hundred per cent, several parties hold minority stakes, so that no single filing shows control and no single threshold is crossed.
The jurisdictions are chosen for the gaps between them rather than for secrecy in the abstract. A chain that runs through a jurisdiction with no public beneficial ownership register, then one that permits corporate directors, then one whose company law recognises nominee arrangements, produces a structure in which each link is opaque in a different way and no single reform closes it.
The role of the corporate director
A recurring feature is the corporate director: a company appointed as director of another company. Where this is permitted, the natural person who actually directs the subsidiary need never be named in any filing, because the directing entity is itself a company whose own directors may be corporate. FATF lists the unrestricted use of legal persons as directors4 among the features that enable concealment, and several jurisdictions have restricted it for that reason.
What layering does not do
Layering conceals ownership. It does not conceal money movement, and this is the practical limit on its effectiveness. Funds still have to reach the beneficial owner eventually, and the payment that does so is visible to whichever institution processes it. Structures that survive scrutiny for years are usually those in which value is extracted through mechanisms that look like ordinary commerce — management fees, intercompany loans, licence royalties, consultancy contracts — rather than through dividends.
How it is caught
Three approaches recur in the public record.
The first is bulk data. Company registers, where they are open and machine-readable, allow the whole population of companies to be searched for shared officers, shared addresses and shared incorporation dates. A structure designed to be invisible to a single lookup is often obvious in aggregate, because the same formation agent built two hundred of them the same way.
The second is the document leak. The ICIJ Offshore Leaks archives and comparable disclosures contain precisely the material that layering is designed to keep out of registers: nominee agreements, declarations of trust, client correspondence and instruction letters. Much of the public understanding of how these structures are built comes from that material.
The third is the follow-the-money approach, which ignores the corporate chain entirely and reconstructs control from payments, guarantees and mandates. FATF’s finding is that those concealing ownership typically exercise control through a combination of direct and indirect control5 rather than one or the other, and that control can be exerted via third parties6 — intermediaries, family members, associates and nominees. Control established that way is visible in mandates and instructions rather than in the register.
