Alternative investment companies (ASI) have for several years remained one of the most widely used tools for organising private investments, venture capital, and family office structures. In practice, however, an increasingly common model is one in which an ASI does not raise capital from a broad group of investors, but instead serves primarily a single entity or a single investor family.

It is precisely at the intersection of these two functions — investment fund and private wealth vehicle — that the most significant regulatory questions arise. The boundary between professional investment activity and a structure serving solely to manage one’s own assets is often far less clear than many investors assume.

In practice, the issues extend well beyond formalities. The way an ASI is designed has a direct bearing on supervisory, tax, and compliance risks, as well as on the ability to raise further capital or execute investment transactions.

ASI as a Modern Family Office

One of the main reasons for the growing popularity of the ASI is its structural flexibility. This construction allows investments to be organised in a relatively efficient manner across:

  • start-ups,
  • VC and PE funds,
  • real estate,
  • alternative assets,
  • private companies,
  • technology projects.

In practice, an ASI is increasingly fulfilling a role similar to that of a professional family office — that is, a platform for the long-term management of private or family wealth.

For post-exit investors, owners of capital groups, or successors to family businesses, an ASI often becomes a tool that allows them to:

  • separate investment assets from operational activity,
  • establish organised governance,
  • pursue a professional investment policy,
  • prepare the structure for succession or future investment rounds.

This does not mean, however, that every ASI with a single dominant investor automatically falls outside the regulator’s interest.

The Dominant Investor vs. the Classic Fund Model

The classic fund model is based on raising capital from multiple investors (LPs), with assets being professionally managed by a manager (ASI manager — ZASI, or an internal model).

In the case of an ASI built for a single investor, the situation differs:

  • capital comes from a single source,
  • the investment strategy is subordinated to the economic interest of a single beneficiary,
  • the structure often has a long-term and succession-oriented character.

The mere presence of a single investor does not in itself constitute a breach of the regulations. The problem arises, however, when an ASI ceases to fulfil the function of a professional investment vehicle and begins to serve exclusively as a passive asset holder.

It is precisely in this area that the greatest regulatory risk emerges.

When an ASI Begins to Resemble a Private Wealth Vehicle

In practice, supervisory authorities and financial institutions are increasingly analysing not only the formal structure of an ASI, but above all its actual economic function.

The risk increases significantly when:

  • there is no real investment policy,
  • investments are exclusively passive in nature,
  • investment decisions are made outside the formal governance framework,
  • the ASI manager (ZASI) fulfils a purely “technical” function,
  • the structure lacks genuine operational substance.

In such cases, the question may arise as to whether the construction in question is genuinely pursuing the objectives proper to an ASI, or merely making use of the regulatory “wrapper” of an investment fund.

Regulatory Risks in Single-Investor ASI Structures

Risk of sham investment activity

One of the most significant risks is a situation in which the ASI’s activity does not constitute professional investment management, but amounts solely to the maintenance of private assets.

In practice, structures that tend to be particularly problematic are those:

  • without a real investment process,
  • without documented governance,
  • without investment activity consistent with the fund’s policy.

Such models may be regarded as artificial constructions lacking adequate economic substance.

Risk relating to the ASI manager (ZASI)

In many family office structures, the ASI manager exists purely in a formal capacity, while actual investment decisions are made by the investor or their advisers.

This is one of the most frequently identified risks during:

  • due diligence,
  • compliance audits,
  • AML/KYC reviews,
  • investment processes.

The absence of genuine exercise of management functions by the ZASI may lead to the entire model being called into question.

AML and compliance risks

An ASI — even one operating solely for a single investor — remains an entity subject to compliance obligations. These relate in particular to:

  • AML/KYC procedures,
  • identification of beneficial owners,
  • monitoring of financial flows,
  • regulatory reporting.

In practice, many family office structures marginalise these obligations, treating the ASI as a private investment holding. This is one of the most common mistakes.

Tax risks

Tax considerations are also of growing importance, particularly in the context of:

  • General Anti-Avoidance Rules (GAAR),
  • economic substance,
  • the genuine commercial purpose of the structure,
  • flows between the ASI and a family foundation or holding company.

The more the structure resembles a private wealth vehicle devoid of genuine investment activity, the greater the risk that its tax effects will be challenged.

Where Do the Boundaries of Permissibility Lie?

There is no single formal “test” that automatically distinguishes a professional ASI from a private investment vehicle. In practice, the totality of circumstances is what matters most.

The following factors carry the greatest weight:

Genuine investment activity

An ASI should pursue an active investment policy consistent with its adopted strategy.

Professional governance

Relevant factors include:

  • investment committees,
  • decision-making procedures,
  • investment documentation,
  • compliance policies.

Economic substance

Analysis is increasingly focused on:

  • who actually manages the investments,
  • where decisions are taken,
  • whether the structure has a genuine business rationale.

Consistency of documentation

Of key importance are:

  • the investment policy,
  • investment agreements,
  • relations with the ZASI,
  • corporate documentation.

ASI for a Single Investor – When Does Such a Structure Make Sense?

A well-designed ASI can be a highly effective tool for:

  • private investors,
  • post-exit founders,
  • business families,
  • family office structures,
  • alternative investors.

The prerequisite for safety, however, is that the entire model is properly designed — not only from a formal perspective, but above all from an operational, regulatory, and tax standpoint.

In practice, the greatest problems arise not when an ASI has a single investor, but when the entire construction has been created solely “on paper”.

Conclusion

An ASI for a single investor can serve as a modern family office and a professional investment vehicle. The mere concentration of capital does not in itself constitute a regulatory problem.

What is of critical importance, however, is whether the structure conducts genuine investment activity, has appropriate governance in place, and satisfies the requirements of compliance and economic substance.

In practice, the boundary between an investment fund and a private wealth vehicle runs not at the level of formal structure, but at the level of the actual manner in which the entire investment model operates.
