When Unregulated Structures Make Sense in Luxembourg

As the investment landscape continues to evolve, fund managers and investors are increasingly focused on solutions that balance efficiency, flexibility and cost control.

Flexibility, speed and efficiency in a changing investment environment

While established fund structures such as Specialised Investment Funds (SIFs), Reserved Alternative Investment Funds (RAIFs) and Société d’Investissement à Capital Variable (SICAV), an investment company with variable capital, remain central to large-scale fundraising and broader investor distribution, non- Alternative Investment Fund (AIF) structures are gaining momentum.

In particular, GP-led Société en Commandite Spéciale (SCSp), a special limited partnership, arrangements are proving to be an effective alternative for a wide range of strategies, including club deals, co-investments and first-time fund launches.

Luxembourg has played a central role in this shift, offering a legal and operational framework that supports tailored structuring without unnecessary complexity.

A flexible and practical structuring option

Luxembourg’s success as a fund domicile has long been rooted in flexibility. The SCSp is a clear example.

Inspired by Anglo-Saxon limited partnerships, the SCSp offers a highly customisable framework in which most terms are defined contractually between the parties. There are no predefined investment restrictions or minimum capital requirements for an unregulated SCSp, subject to the structure not falling within a regulated product regime or otherwise triggering applicable AIFMD requirements, and governance arrangements can be shaped to reflect the specific objectives of the strategy and investor group.

From a tax perspective, the SCSp is generally treated as tax transparent, which aligns well with international private market structures and investor expectations.

Light, fast and cost efficient

Operational simplicity is a key driver behind the growing use of non AIF structures.

In many cases, provided the structure does not qualify as an AIF or fall within a regulated product regime, there is no requirement for Commission de Surveillance du Secteur Financier (CSSF) approval, no obligation to appoint an authorised Alternative Investment Fund Manager (AIFM) and fewer ongoing regulatory and reporting obligations. This can significantly reduce both time to market and ongoing operating costs.

For managers launching new strategies, testing investor appetite or executing transactions with a defined group of participants, this lighter framework can offer a meaningful advantage.

Well suited to club deals and co-investments

Non-AIF GP-led SCSp structures are particularly effective for club deals involving a limited number of known investors.

They allow managers and sponsors to agree bespoke governance, economic and reporting terms without the constraints associated with regulated fund frameworks. This makes them well suited to focused investment strategies, joint ventures and co investment opportunities where speed and alignment are critical.

A strong and growing market trend

Luxembourg remains one of the largest fund centres globally, with a substantial volume of assets under management across traditional and alternative strategies. Within this ecosystem, the use of flexible partnership structures has continued to grow, particularly in private equity, private debt and real assets.

This trend reflects a broader market preference for structures that combine contractual freedom with a well understood and credible legal environment.

Start simple and scale over time

For many managers, non-AIF structures also offer a natural entry point into Luxembourg’s fund ecosystem.

An unregulated SCSp can be used to establish a track record, execute initial investments and build investor relationships. As the strategy matures and fundraising expands, the structure can later be transitioned into, or restructured as, a RAIF or other suitable regulated or semi-regulated vehicle to support wider distribution.

This ability to evolve over time is one of the key reasons non AIF structures continue to attract interest.

Conclusion

Non AIF structures in Luxembourg offer a compelling combination of flexibility, speed and efficiency. For managers and investors seeking a practical and cost conscious approach, particularly in the context of club deals, co investments or emerging strategies, they represent a well established and increasingly popular option within the broader Luxembourg fund landscape.
