What is AIFMD Annex IV reporting?
AIFMD Annex IV reporting is the periodic regulatory reporting that Alternative Investment Fund Managers (AIFMs) must submit to their National Competent Authority (NCA) under Article 24 of the Alternative Investment Fund Managers Directive (Directive 2011/61/EU). The name comes from Annex IV of Commission Delegated Regulation (EU) No 231/2013 (the “AIFMR”), which sets out the pro-forma reporting template. NCAs pass the data to ESMA and the ESRB to monitor systemic risk in the alternative investment fund industry.
Legal basis and guidance
The obligation rests on three layers of text that you should read together:
- Directive 2011/61/EU, Article 24 — the primary obligation. Article 24(1) covers markets and instruments traded and the main exposures of each AIF; Article 24(2) covers detailed risk, liquidity and concentration information; Article 24(4) adds information where an AIF employs leverage on a substantial basis.
- Commission Delegated Regulation (EU) No 231/2013, Articles 110-111 and Annex IV — the reporting frequency, content and the actual template fields.
- ESMA Guidelines (ESMA/2014/869) and the ESMA IT technical guidance / data-quality validation rules — the field-by-field definitions, code lists and the XML schema used for filing. This guide cites the numbered ESMA guideline paragraphs throughout.
Who has to report?
Both authorised AIFMs (above the thresholds of Article 3(2) AIFMD) and registered “sub-threshold” AIFMs (Article 3(3)(d)) report, although sub-threshold managers file a reduced dataset. Reporting is done per AIFM (the AIFM-level file) and per AIF managed or marketed in the EEA (one AIF file per fund, and where relevant per sub-fund of an umbrella).
Reporting frequency
Frequency depends on assets under management (AuM) and leverage, as set out in Article 110 AIFMR. The commonly applied matrix is:
| AIFM / AIF profile | Reporting frequency |
|---|---|
| Registered (sub-threshold) AIFM under Art. 3(3)(d) | Annually |
| Authorised AIFM, total AuM ≤ €100m | Annually |
| Authorised AIFM, total AuM €100m–€1bn | Half-yearly |
| Authorised AIFM, total AuM > €1bn | Quarterly |
| Any individual AIF whose AuM > €500m | Quarterly (for that AIF) |
| Unleveraged AIF investing in non-listed companies/issuers to acquire control | Annually |
Deadlines: reports are due within one month of the end of the reporting period; funds of funds get an extra 15 days. When an AIFM's or AIF's frequency or content obligation changes mid-year, the transition is reported using the change codes in Appendix E and the status-change matrices in Appendices F–G. Always confirm the exact cut-off and any national add-ons with your NCA (in Luxembourg, the CSSF).
How the report is structured
The dataset is delivered as an XML file that validates against the ESMA schema and passes the ESMA data-quality engine (DQEF) rules. Conceptually it is split into the templates covered by this guide:
| File | Legal basis | Question range | Purpose |
|---|---|---|---|
| AIFM file | Art. 24(1) | 1–38 | Manager-level identification, principal markets/instruments, total AuM |
| AIF file — 24(1) | Art. 24(1) | 1–120 | Fund identification, strategy, main exposures, geography, investor concentration |
| AIF file — 24(2) | Art. 24(2) | 121–280 | Detailed exposures, market/counterparty/liquidity risk, historical performance |
| AIF file — 24(4) | Art. 24(4) | 281–299 | Leverage, borrowing, rehypothecation, controlled structures |
Each field below is documented with four layers: Theory (what it is and its legal basis), ESMA guidelines (the specific reporting guidance), an Example (a concrete illustration) and Practical guidance (how to complete it and common pitfalls). The Theory and ESMA-guidelines layers are grounded in Directive 2011/61/EU, Delegated Regulation (EU) No 231/2013, the ESMA guidelines (ESMA/2014/869), the field text of the reporting template and the ESMA XSD schemas; the Example layer is an illustrative construction written to aid understanding, not a quotation from ESMA. Reference code lists are collected in the appendices. Monetary values are reported in the base currency of the AIF unless stated otherwise, with the EUR conversion carried in the file.
The XML file in practice (technical)
Each submission validates against the ESMA XSD schema — this guide reflects the AIFMD_DATMAN (manager) and AIFMD_DATAIF (fund) schemas, v1.2, plus the shared AIFMD_REPORTING_DataTypes types. The root element (AIFMReportingInfo / AIFReportingInfo) carries three attributes — ReportingMemberState, Version (the schema version) and CreationDateAndTime (UTC) — and then one or more records:
- Reporting record (
AIFMRecordInfo/AIFRecordInfo): a normal report. The filing type isINITfor an initial filing orAMNDto amend one already submitted. - Cancellation record (
CancellationAIFMRecordInfo/CancellationAIFRecordInfo): withdraws a previously submitted report, identified by the national code(s), reporting period type and year, withCancelledRecordFlag = C.
Corrections are therefore made with AMND — not by incrementing a version number — and full withdrawals with a cancellation record. The technical enumerations (filing types, content types, period types and the AIFM/AIF reporting-category codes) are collected in Appendix H.

AIFMD II and the future of Annex IV reporting
AIFMD II — Directive (EU) 2024/927, amending the AIFMD and the UCITS Directive — entered into force in April 2024 with a transposition deadline of 16 April 2026. It materially expands supervisory reporting: the current Annex IV dataset will be broadened (for example more granular delegation, liquidity-management-tool, and loan-origination data), and Article 24 is being amended so that reporting is no longer limited to the “principal” markets and instruments.
The detailed new template will be set by Regulatory and Implementing Technical Standards (RTS/ITS) developed by ESMA, with the revised reporting expected to apply after the technical standards are finalised (widely anticipated around 2027). Until the new standards take effect, the fields described in this guide — based on Delegated Regulation (EU) No 231/2013 and ESMA/2014/869 — remain the applicable template. FUND XP tracks the AIFMD II implementing measures and updates client reporting ahead of each go-live.
Action point: if you report today under the current template, budget for a data-model extension rather than a replacement — most existing fields carry over, but new data points (notably liquidity management tools and delegation arrangements) will need to be sourced from systems that may not feed your reporting today.

What is AIFMD Annex IV reporting?
It is the periodic transparency report AIFMs file with their National Competent Authority under Article 24 of Directive 2011/61/EU, using the template in Annex IV of Delegated Regulation (EU) No 231/2013. It describes each AIF's markets, instruments, exposures, leverage, liquidity and risk profile so regulators can monitor systemic risk.
Who has to file an Annex IV report?
Both authorised AIFMs (above the Article 3(2) thresholds) and registered sub-threshold AIFMs under Article 3(3)(d). Authorised managers report a full dataset; sub-threshold managers report a reduced set. A report is filed at manager level (AIFM file) and for each AIF managed or marketed in the EEA.
How often must the report be submitted?
Depending on assets under management and leverage: annually, half-yearly or quarterly. As a rule of thumb, authorised AIFMs above €1bn report quarterly, €100m–€1bn half-yearly, and any single AIF above €500m is reported quarterly. Reports are due within one month of period end (six weeks for funds of funds).
What is the difference between Article 24(1), 24(2) and 24(4) reporting?
Article 24(1) captures identification and the principal markets, instruments and exposures. Article 24(2) adds detailed risk, liquidity, counterparty and concentration data. Article 24(4) applies only where an AIF uses leverage on a substantial basis (gross leverage above 3× NAV) and covers borrowing, leverage measures and controlled structures.
In which format is the report filed?
As an XML file that validates against the ESMA reporting schema and passes ESMA's data-quality validation rules. Monetary amounts are reported in the AIF's base currency, with EUR conversion carried in the file. Most NCAs, including the CSSF in Luxembourg, accept the XML through a dedicated transmission channel.
What is 'leverage on a substantial basis'?
Under Article 111 AIFMR, leverage is employed on a substantial basis when the AIF's exposure calculated under the gross method exceeds three times its net asset value. When that threshold is crossed, the Article 24(4) fields (leverage sources, borrowing and controlled structures) must be completed.
How are assets under management (AuM) calculated for reporting?
Per Articles 2 and 10 AIFMR (guideline ¶51): value every position, then add the leverage-inclusive exposure — derivatives are converted into the market value of an equivalent position in the underlying. AuM is always reported in EUR using the ECB conversion rate as at the last business day of the period; where no ECB rate exists, the AIFM states the rate used.
What happens when an AIF's or AIFM's reporting obligation changes mid-year?
You report the transition using a change code. The before/after status is mapped in the AIFM matrix (Appendix F, 72 cases) and the AIF matrix (Appendix G, 2,352 cases), and the resulting periods are governed by the frequency change codes in Appendix E (YQ, YH, HQ, QY, QH, NQ…). For example, an AIFM moving from yearly to quarterly reporting in Q1 reports Q1–Q2 first, then Q3 and Q4 separately (code YQ).
Do I report at share-class level?
No — reporting is at AIF (fund/sub-fund) level. Share classes only appear for identification (Q33–40): you list each class's ISIN/SEDOL/national codes, but returns, NAV and exposures are reported for the AIF as a whole, not per class (guideline ¶129).
How do feeder funds and umbrella structures report?
Each sub-fund of an umbrella is generally reported as a separate AIF. A feeder AIF identifies its master(s) at Q41–44 and, where relevant, looks through to the master's exposures. Both the umbrella name and the sub-fund name are reported for identification (guideline ¶52).
What if I have to rely on estimates or assumptions?
Disclose them in the assumptions section (Q14–15), referencing the question number concerned. Where you report a “0” value for a risk measure, ESMA expects you to explain why (guideline ¶111). Assumptions must be applied consistently period to period.
Does AIFMD II change Annex IV reporting?
Yes. Directive (EU) 2024/927 expands the dataset and removes the limitation to 'principal' markets and instruments. The detailed new template will be defined by ESMA technical standards, expected to apply around 2027. The current template remains applicable until then.
Where do I get the asset-type, strategy and status codes?
They are ESMA-defined code lists. This guide reproduces the key ones in the appendices: the asset-type taxonomy (Appendix A), investment strategy codes (B), investor group codes (C), risk-measure codes (D) and the frequency/status change codes (E–G).
