Annex IV Reporting Explained: A Practical Guide for AIFMs

For Alternative Investment Fund Managers (AIFMs), regulatory reporting is an unavoidable part of operating within the European alternative investment landscape. One of the most significant and detailed reporting obligations under the Alternative Investment Fund Managers Directive (AIFMD) is Annex IV reporting.

Though time consuming and burdensome, Annex IV reporting plays a critical role in regulatory oversight and risk monitoring across the EU. Understanding what to report, the authorities to report to , and how to accurately compile reporting fields is essential for complying with regulatory requirements and avoiding regulatory concerns.

This guide breaks down Annex IV reporting in a clear and practical way, helping AIFMs understand their obligations and in turn navigate the reporting process with confidence.

What Is Annex IV Reporting?

Annex IV reporting refers to the periodic regulatory reporting obligation set out under Article 24 of the AIFMD, using the reporting templates prescribed in Annex IV of the Directive.

In simple terms, Annex IV requires AIFMs to submit structured regulatory information about:

• The AIFM itself
• The alternative investment funds (AIFs) it manages or markets
• Investment activity, risk exposure, leverage, and liquidity

These reports are submitted to the relevant National Competent Authority (NCA), such as the Malta Financial Services Authority in Malta (MFSA), through a regulator-specific submission portal.

The reporting format is generally XML-based and follows technical standards issued by European Securities and Markets Authority (ESMA).

Why Does Annex IV Reporting Matter?

The primary objective of Annex IV reporting is to give regulators visibility and transparency over the alternative investment fund sector.

Through Annex IV data, regulators are able to:

• Monitor systemic risk within the AIF market
• Assess leverage levels and liquidity profiles
• Identify concentration and counterparty risks
• Evaluate potential threats to financial stability at both fund and manager level

Annex IV reporting shall not be seen as ‘just a compliance exercise’. Inaccurate or inconsistent data can raise supervisory concerns, trigger follow-up questions, or lead to regulatory findings.

Who Is Required to File Annex IV Reports?

Annex IV reporting applies to AIF managers domiciled in the EU and may also apply to AIF managers domiciled outside of the EU.

EU AIFMs

EU-authorised AIFMs must submit Annex IV reports for:

• Each AIF they manage
• Each reporting period applicable to their structure

The above shall be submitted to the EU-authorised AIFM relevant Competent Authority

Non-EU AIFMs

Non-EU AIFMs may also be subject to Annex IV reporting in instances where they market AIFs in the EU under National Private Placement Regimes (NPPRs).

In such case, it is important to note that a separate Annex IV report is required in each EU jurisdiction where the AIF is marketed.
 For example, a non-EU AIFM marketing a fund in Germany, the Netherlands, and Ireland must typically submit three separate Annex IV filings to three different NCAs.

This multi-jurisdiction requirement can significantly increase the reporting burden for non-EU managers.

What Information Is Included in an Annex IV Report?

Annex IV reports are data-heavy and highly structured. They include, among other things:

• AIFM information (authorisation details, regulatory status)
• AIF details (structure, strategy, domicile)
• Assets under management (AUM)
• Investment strategies and geographic exposure
• Leverage calculations, including:
  • Gross method
  • Commitment method
• Liquidity profiles of assets and liabilities
• Counterparty exposure
• Risk concentration metrics

Regulators expect this information to be:

• Accurate
• Consistent with offering documents and financial statements
• Aligned with the AIFM’s risk management framework

Reporting Frequency: How Often Do AIFMs Need to File?

Annex IV reporting frequency depends on several factors, including:

• The size of the AIF
• The investment strategy
• Whether the AIF uses leverage

An AIFM may be required to file Annex IV reports:

• Annually
• Semi-annually
• Quarterly

Determining the correct frequency is critical. Filing too infrequently can lead to non-compliance, while filing unnecessarily often can create avoidable operational burden.

Annex IV Reporting Deadlines

Annex IV reports must be submitted within 30 calendar days from the end of the reporting period.

For example:

• A reporting period ending 31 December 2024 must generally be submitted by 30 January 2025

Deadlines are strict, and regulators expect filings to be both timely and accurate.

What Happens If Annex IV Reports Are Late or Incorrect?

Failure to submit accurate and timely Annex IV reports may result in:

• Regulatory queries or supervisory follow-ups
• Requests for resubmission or clarification
• Administrative penalties
• Increased regulatory scrutiny

Repeated issues can also impact the regulator’s view of an AIFM’s governance, risk management, and compliance culture.

Why Annex IV Reporting Is Often Challenging

Although the reporting framework is harmonised at EU level, implementation varies across jurisdictions.

Common challenges include:

• Different NCA submission portals
• Jurisdiction-specific validation rules
• Data gaps between administrators, portfolio managers, and depositaries
• Complex leverage and liquidity calculations
• Changes in fund structure or strategy mid-period

For non-EU AIFMs and managers with multiple funds, these challenges can quickly multiply.

How Professional Annex IV Reporting Support Helps

Many AIFMs choose to seek specialist support for Annex IV reporting, particularly where:

• Multiple jurisdictions are involved
• Internal resources are limited
• Fund structures are complex

Professional support typically covers:

• Applicability and scoping assessments
• Data collection and validation
• XML report preparation
• Consistency checks against regulatory standards
• Ongoing advisory support as strategies evolve

This approach helps reduce regulatory risk while allowing internal teams to focus on core investment and operational activities.

Annex IV reporting is a central component of AIFMD compliance and a key regulatory tool for monitoring the alternative investment fund sector. While the process can be complex, a clear understanding of the requirements, combined with the right expertise, makes compliance far more manageable.

For AIFMs, getting Annex IV reporting right is not just about meeting deadlines. It is about demonstrating transparency, sound risk management, and strong regulatory governance.
