A depositary is an independent regulated entity appointed by certain investment funds to provide asset safekeeping, oversee key fund operations and help ensure compliance with applicable regulatory requirements.
In Luxembourg, depositary oversight is required for many Alternative Investment Fund (AIF) structures under the Alternative Investment Fund Managers Directive (AIFMD) framework, depending on the fund, the Alternative Investment Fund Manager’s (AIFM’s) status and the applicable marketing regime. Its role is to support investor protection by introducing an independent control layer over asset ownership, cash flows and compliance with fund documentation.
Core responsibilities
For alternative investment funds holding non financial assets, depositary responsibilities typically include:
Asset record keeping and ownership verification for assets other than financial instruments
Cash flow monitoring, ensuring that investor subscriptions and fund cash movements are properly controlled
Oversight duties, including checks on investment activity against fund documentation and applicable regulations
The depositary acts independently from the fund manager and administrator and performs its role in the interests of investors.
Who can act as a depositary in Luxembourg?
In Luxembourg, depositary services must be provided by entities authorised and supervised by the Commission de Surveillance du Secteur Financier (CSSF).
For alternative investment funds investing in illiquid or non financial assets, this role may be performed by a Professional Depositary of Assets Other Than Financial Instruments (PDAOFI), subject to specific regulatory and organisational requirements.
A formal depositary agreement governs the relationship, setting out access rights, reporting obligations and information flows.
What is depositary lite?
In specific AIFMD marketing scenarios, a depositary lite model may apply, including where non-EU AIFMs market certain EU or non-EU alternative investment funds (AIFs) into EU jurisdictions under National Private Placement Rules (NPPR).
This model provides essential AIFMD-aligned oversight while reflecting the nature of the underlying assets and the distribution model.
How the depositary fits within the Luxembourg ecosystem
The depositary operates alongside other service providers but maintains a clearly defined and independent role.
It interacts with:
AIFMs, in relation to oversight and reporting
Fund administrators, for access to accounting, NAV and investor information
Auditors and legal advisers, to support transparency and regulatory compliance
The depositary does not make investment decisions or commercially approve transactions. Instead, it performs ex post oversight checks to verify that activities are carried out in accordance with fund documentation and applicable regulations.
