Fund accounting in Luxembourg: who may keep the books, for which vehicle.

Fund accounting covers investment entries, reconciliations, net asset value (NAV) data and reporting. Provider eligibility depends on the vehicle, the functions assigned and the provider's status. Financial Services Luxembourg, a licensed accountant (auth. 10077274), supports accounting for eligible GPs, holdings, SPVs and other entities after assessing professional thresholds and the engagement. Agreed accounting data are provided to the authorised parties; the firm does not perform UCI administration or official NAV calculation. This page explains those responsibilities and the accounting work that may be entrusted to the firm.

In short

Fund accounting produces an investment vehicle's records and financial statements. It feeds NAV, investor accounts and reporting. The accounting and NAV calculation function forms part of UCI administration assigned to authorised providers; separating tasks does not remove the need to assess the vehicle's regime and the provider's eligibility.

Legal basis

The accounting framework depends on the vehicle's applicable legislation and constitutional documents: Lux GAAP (law of 19 December 2002 as amended), or IFRS where permitted. The RAIF (law of 23 July 2016), SIF (law of 13 February 2007), SICAR (law of 15 June 2004) and AIFM (law of 12 July 2013) regimes must be read with CSSF Circular 22/811, as amended by 25/900, and its FAQ. Financial Services Luxembourg acts within its licensed accountant scope (auth. 10077274, RCS B213987, VAT LU29299810), under AED AML/CFT supervision. This status does not constitute UCI administrator authorisation or permission to perform every fund function.

Key takeaway

  • Accounting feeds NAV and reporting; the vehicle's regime and the provider's status determine which functions it may perform.
  • Financial Services Luxembourg supports eligible entities and engagements within its professional scope; UCI administration and official NAV calculation remain with authorised parties.
  • The choice between Lux GAAP and IFRS depends first on the applicable accounting regime, then on the vehicle's documents and investor needs.
  • Capital calls, distributions, equalisation, waterfall and carried interest are booked and reported on the fund's schedule.
  • Financial Services Luxembourg coordinates with the AIFM, depositary and auditor; NAV deadlines are met, reserved acts stay with partners.
  • Pricing on a quote basis, depending on the vehicle, portfolio complexity and NAV frequency.

Technical definitions and responsibilities

Capital account

A capital account tracks a partner's position under the vehicle agreement and accounting framework: contributions, allocated results, expenses and distributions. Its balance is not automatically identical to a fund unit's net asset value.

Distribution waterfall

A distribution waterfall defines how distributable proceeds are allocated between investors and sponsors, potentially including return of capital, a preferred return and carried interest. Calculations depend on the LPA and must be documented and reviewed by the responsible parties.

What is fund accounting in Luxembourg?

Fund accounting produces the records feeding NAV calculation and investor reporting. Provider eligibility depends on the vehicle’s regime, the functions assigned and the provider’s own status. Falling below the AIFM thresholds does not remove the need to assess UCI administration rules and the provider’s professional scope.

What is the difference between fund accounting and fund administration?

Accounting and NAV calculation form one UCI administration function assigned to authorised providers, alongside registrar and transfer agency. Separating these tasks does not automatically make them unrestricted activities: provider eligibility and delegation requirements must be assessed for each assigned function under the applicable regulatory framework.

Is a RAIF subject to the Luxembourg standard chart of accounts?

A RAIF required to file financial data with the RCS is subject to the standard chart of accounts unless an exemption applies. CNC 19/018 excludes the prudential-supervision exemption but recognises the exemption for accounts prepared and published under IFRS as adopted by the European Union.

CSSF Circular 24/856 addresses NAV errors for UCITS, Part II UCIs, SIFs and SICARs, and certain ELTIFs, MMFs, EuVECAs and EuSEFs under its conditions. A RAIF can therefore be covered. Neither RAIF status nor the SCSp legal form alone establishes an exclusion; the vehicle’s applicable regime must be assessed.

What is fund accounting in Luxembourg?

Fund accounting is the bookkeeping of a Luxembourg investment vehicle and its holding structures, through to the calculation of net asset value (NAV) and investor reporting. It is the numerical foundation underpinning the valuation of units, distributions, regulatory reporting and the annual audit. Without rigorous fund accounting, neither the LPs nor the AIFM has a reliable picture of the vehicle's performance and position.

In Luxembourg, Europe's leading fund domicile, this discipline applies across the full range of vehicles: RAIF, SIF, SICAR, and also special limited partnership (SCSp) structures, very common in private equity and private debt. Each vehicle type has its own valuation and reporting constraints, but the heart of the discipline is the same: faithfully record investments, value them, prepare the NAV calculation and deliver clear information to investors.

Fund accounting goes well beyond data entry. It requires understanding the capital structure (commitments, calls, distributions), the profit-sharing mechanics (waterfall, carried interest, equalisation), and the requirements of the chosen accounting framework. It is technical accounting, sitting at the crossroads of fund law, finance and Luxembourg regulation.

Financial Services Luxembourg assesses accounting for eligible GPs, holdings, SPVs and other structures according to the engagement and professional thresholds. Fund administration, official NAV calculation, management, depositary services and audit remain assigned to authorised providers. Coordination does not transfer their regulated functions to the firm.

Fund accounting or fund administration: do not confuse the two

UCI administration comprises several functions, including accounting and NAV calculation assigned to authorised providers, as well as registrar and transfer agency. Calling a service accounting does not by itself place it outside the administration framework. Task allocation must comply with the rules governing the vehicle, provider and delegations.

Fund accounting, by contrast, focuses on the bookkeeping of the vehicle and its structures, the NAV inputs, capital accounts and reporting. It is the "numbers and NAV" block of the whole. Many structures, especially in private equity and private debt, need precisely this solid accounting block, with the AIFM or a dedicated agent handling the register and transfer side.

Financial Services Luxembourg accepts accounting work permitted for eligible entities. Agreed entries, reconciliations and data are supplied to the appointed parties. Valuation, official NAV calculation and approval, and the investor register remain under the responsibilities set by legislation and mandates; final approval by an AIFM does not remove a provider's obligation to verify its own eligibility.

Understanding this distinction matters when structuring your operating model: it determines who does what, where information flows, and how responsibilities are shared between the AIFM, the depositary, the administration and the fund's accounting.

Investment entries and valuation of positions

The day-to-day of fund accounting begins with investment entries: acquisitions and disposals of securities, loans and drawings in private debt, capital calls and repayments on holdings, accrued interest, capitalised acquisition costs. Every portfolio transaction must be recorded accurately, in the right currency, on the right date, with the appropriate accounting treatment under the chosen framework.

Next comes the valuation of positions. This is a decisive step, because the fair value of assets feeds directly into the NAV. In private equity and real estate, assets are unlisted: their valuation relies on models, comparable transactions or appraisals, and valuation responsibility lies with the AIFM under the AIFM framework. Fund accounting integrates these valuations, ensures their traceability and controls them against the entries.

For listed or liquid positions, valuation relies on market prices and reliable price sources. In every case, the fund accountant reconciles accounting positions with the depositary's and counterparties' inventories, identifies discrepancies and documents them. This audit trail is essential to NAV reliability and to a smooth annual audit.

For eligible entities within the structure, Financial Services Luxembourg records transactions and valuations supplied by the appointed responsible parties, retains supporting documents and records discrepancies. The accounting engagement is not a separate mandate to value the fund’s assets.

Net asset value (NAV) calculation and its controls

The NAV calculation, signed off by the authorised central administrator, is the culmination of fund accounting. The NAV represents the value of the fund's assets, less its liabilities and provisions, and is the basis for valuing the units or shares held by investors. It is the number LPs look at, the one underpinning subscriptions, redemptions, distributions and performance measurement.

The fund documents set the NAV calculation frequency, which may be daily, monthly, quarterly or semi-annual depending on the vehicle. The appointed parties aggregate positions, income, expenses and other adjustments by share class. Financial Services Luxembourg supplies only accounting data for eligible entities and reconciliations specified in its engagement letter; NAV calculation remains with the authorised provider.

NAV controls include positions, prices, exchange rates and movements between periods. They are performed by the parties assigned that function. Our accounting reconciliations and supporting documents evidence the items within the engagement and support those controls without replacing them.

NAV deadlines determine when each party must deliver its data. Financial Services Luxembourg organises delivery of the agreed accounting inputs and flags missing documents or discrepancies. The timetable and responsibilities are defined before the engagement begins.

Capital calls, distributions and equalisation

Closed-ended vehicles in private equity, private debt or real estate operate on the basis of commitments drawn down progressively. Fund accounting must faithfully reflect this capital lifecycle: capital calls (drawdowns), investments, income and repayments, then distributions to investors as disposals and cash flows come in.

Each capital call is booked per investor, consistent with their commitments and the called portion. Each distribution is allocated according to the mechanics set out in the LPA. This booking feeds the individual capital accounts, which track for each LP their commitments, capital called, capital repaid, distributions received and share of profit.

Equalisation is a particular mechanism of multi-closing funds. When new investors join the fund after the first closings, equalisation restores fairness between LPs: incoming investors compensate existing LPs for the elapsed period, often with an equalisation interest. Fund accounting calculates and records these equalisation flows, which can be technical and demand great precision.

Within accepted eligible engagements, Financial Services Luxembourg records capital movements and documents reconciliation to the instructions and evidence received. Capital call and distribution decisions, the investor register and distribution of information remain the responsibility of the appointed parties.

Waterfall, carried interest and capital accounts

Profit-sharing between LPs and the general partner follows a contractual mechanism, the distribution waterfall, defined in the LPA. It organises the order in which cash flows are distributed: return of capital, hurdle rate (preferred return), GP catch-up, then sharing of the surplus between LPs and GP. Fund accounting translates this cascade into figures at each distribution.

Carried interest is the share of capital gains accruing to the general partner or management team once the hurdle is met. Its calculation can be complex: deal-by-deal or whole-of-fund carried interest, with or without clawback, subject to escrow or not. Fund accounting calculates the carried interest due or provisioned, consistent with the waterfall and the LPA terms, and documents it for the audit.

Capital accounts are the synthesis, investor by investor, of all this mechanics: commitments, capital called and repaid, distributions, share of profit, interest and carried interest. They are the reference for each LP and a central element of investor reporting. Their accuracy is essential, as they translate directly the economic rights of each party.

Financial Services Luxembourg’s work on the waterfall, carried interest and capital accounts is defined in the engagement letter by eligible entity and available data. It documents accounting entries and reconciliations. Validation of investor entitlements and distributions remains with the parties designated in the fund documents.

Lux GAAP or IFRS: choosing the fund's accounting framework

Fund accounting can be prepared under Lux GAAP (Luxembourg) or under IFRS. The choice is not neutral: it depends on the fund documents, the type of investors, reporting expectations and, sometimes, the requirements of an institutional investor or a parent consolidating under IFRS.

Lux GAAP, based on the law of 19 December 2002 as amended, offers great flexibility and remains widely used for Luxembourg investment vehicles, particularly when they value their holdings at fair value. IFRS, for its part, are often preferred by funds whose international investors expect a comparable global framework, with precise consolidation and presentation rules.

The choice of framework structures the whole of fund accounting: treatment of financial instruments, fair-value measurement, presentation of equity and units, notes to the accounts. It must be set at set-up and applied consistently from one year to the next. Financial Services Luxembourg keeps and reports in the chosen framework, and can support the upstream thinking depending on your investor profile.

Where the vehicle sits within a group structure with entities to consolidate, fund accounting dovetails with consolidation work. We ensure consistency between the fund's accounts, those of the SPVs and, where relevant, the consolidated statements expected by investors or the top structure.

Investor reporting and LP reporting

Reporting is the visible purpose of fund accounting. Investors, and in particular the LPs of closed-ended funds, expect regular, clear and reliable information on the value of their units, their capital accounts, fund performance and the period's transactions. Quality reporting is a decisive trust factor in investor relations.

Investor reporting typically includes the NAV per share class, the statement of individual capital accounts, the summary of the period's calls and distributions, performance indicators (IRR, multiples) where expected, and commentary on transactions. Its form and frequency are set by the fund documents and the AIFM, from monthly to semi-annual depending on the vehicle.

Alongside investor reporting sits regulatory reporting, whose responsibility lies primarily with the AIFM, but which relies on the accounting data we produce. Fund accounting thus feeds the reporting chain, providing figures that are accurate, on time, and consistent from one production to the next.

Financial Services Luxembourg prepares agreed accounting reporting inputs for eligible entities and supplies them to the appointed responsible parties. Final content, approval and distribution of fund reporting follow the responsibilities set by the fund documents and provider mandates.

Coordination with the AIFM, depositary and auditor

A regulated Luxembourg fund operates as an ecosystem: the AIFM (manager), the depositary, the administration, the accounting and the auditor. Fund accounting is never an isolated activity: it continually dovetails with these parties, and the quality of coordination drives both meeting NAV deadlines and the smoothness of the close.

Within our engagement, we exchange agreed accounting data and supporting documents with the AIFM and administrator. Responsibility for valuation, official NAV calculation and regulatory reporting remains with the authorised parties under the legislation and mandates. Relevant cash and position reconciliations with the depositary are documented so that the fund's responsible parties can perform their controls.

We prepare accounts and audit evidence for entities covered by the engagement and respond to the approved statutory auditor’s requests. Financial Services Luxembourg is not the fund’s auditor: statutory audit remains reserved to the authorised professional. The file identifies our work and documents obtained from the other parties.

This coordination is precisely the added value of well-kept fund accounting. Beyond producing figures, it slots cleanly into the fund's regulated structure, respecting each party's role and meeting shared deadlines. Reserved acts stay with the duly qualified partners; Financial Services Luxembourg keeps the books and orchestrates the information flows around it.

Annual close, vehicle accounts and deadlines

The annual close is the high point of the fund's accounting cycle. It leads to the vehicle's annual accounts, prepared in the chosen framework (Lux GAAP or IFRS), with the notes and information expected by investors and the auditor. The fund accounting carried out throughout the year prepares this close, which must be both accurate and met on time.

The audit inputs we prepare correspond to the accepted entities and work: evidence of positions, valuations received, cash reconciliations and capital movements. NAV calculations and other documents produced by the fund’s providers are identified as such. Preparing a file does not constitute audit or certification.

Deadlines structure the entire year: NAV deadlines during the year, investor reporting deadlines, and the close and filing calendar at year-end. Financial Services Luxembourg drives this calendar, anticipates activity peaks and secures the upstream so that nothing is produced under pressure. Meeting deadlines protects the investor relationship and the vehicle's compliance.

At the end of the close, the vehicle has audited annual accounts, complete investor reporting and a consistent audit trail. This is the proof of well-controlled fund accounting, and the basis for a calm new year. Financial Services Luxembourg supports this cycle year after year, as a stable point of contact in your structure.

Why entrust your fund accounting to Financial Services Luxembourg?

Financial Services Luxembourg is a licensed accountant (authorisation 10077274, RCS B213987, VAT LU29299810), subject to AED AML/CFT supervision. The firm assesses accounting assignments for eligible GPs, holdings, SPVs and other entities. RAIF, SIF, SICAR or SCSp status alone does not establish eligibility: the vehicle's classification, functions and professional thresholds are assessed before acceptance.

The engagement letter specifies the entries, reconciliations, management reports and closing records to be produced for the accepted entities. Any investor accounts and contractual calculations are prepared only within that scope. The firm does not replace the UCI administrator or the provider responsible for official NAV calculation; management, regulatory valuation, depositary functions and audit remain with authorised parties.

We work as a dedicated, multilingual point of contact, able to liaise with a sponsor, an AIFM, a depositary and an auditor within a single file. Our demand for responsiveness and respect for deadlines, which characterises all our engagements, applies fully to fund accounting, where NAV punctuality is essential.

The exact scope, data delivery frequency and reporting requirements determine the cost: we quote after assessing the entities and requested work. The proposal identifies the accepted accounting services, coordination and work performed by authorised professionals, alongside our fund structuring and AIFM support services.

Scope my vehicle

The process, step by step

01

Vehicle scoping

We assess the vehicle's classification, the manager's status, the functions to be assigned and the licensed accountant's professional thresholds. The Lux GAAP or IFRS framework, parties and deadlines are then defined. The engagement letter identifies eligible entities, accepted work and the authorised providers' responsibilities.

02

Set-up

For the entities included in the engagement letter, we set up the chart of accounts, take over positions and opening balances and organise supporting documents. Capital account, waterfall and carried interest data are handled only within the accepted accounting scope and under the applicable documents.

03

Ongoing production

Within the accepted scope, we record transactions, incorporate valuations supplied by the appointed responsible parties and prepare agreed reconciliations and accounting data. Authorised providers perform NAV calculation, control and approval functions and regulatory reporting under their mandates.

04

Close & audit

We prepare accounts and supporting documents for the entities covered by the engagement and the agreed audit inputs. Responsibility for preparing, signing, auditing and filing the fund’s accounts remains allocated to the competent parties under the legislation and mandates.

FAQ

Frequently asked questions

What is the difference between fund accounting and fund administration?

Accounting and NAV calculation form one UCI administration function assigned to authorised providers; registrar and transfer agency are other components. Dividing tasks does not remove eligibility or delegation requirements. Financial Services Luxembourg undertakes eligible accounting work defined in the engagement letter; UCI administration and official NAV calculation remain assigned to authorised providers.

Which vehicles can you account for?

We assess GPs, holdings, SPVs and other entities within an investment structure according to their classification, obligations and the licensed accountant's professional thresholds. A fund or an unregulated SCSp is not automatically eligible for all our services. The AIFM, administrator and relevant advisers confirm the allocation of functions before the engagement begins.

Do you work in Lux GAAP or IFRS?

The framework follows the vehicle’s applicable rules first, then the permitted options and fund documents. For eligible engagements, we assess Lux GAAP or IFRS requirements. A RAIF required to file with the RCS generally falls under the standard chart of accounts; CNC 19/018 provides an exemption when its accounts are prepared and published under IFRS adopted by the European Union.

Do you prepare the net asset value (NAV) calculation?

We may prepare accounting data and reconciliations expressly included in an eligible engagement. UCI administration, official NAV calculation and finalisation remain with the authorised parties under the vehicle's regime and their mandates. Data frequency and delivery deadlines are agreed with them after the file is assessed.

Do you handle capital calls, distributions and equalisation?

Within the accounting scope of an eligible engagement, we record calls and distributions based on the decisions and evidence received and document reconciliations. Any requested equalisation work must be expressly scoped. Decisions, the investor register and distribution of notices remain with the appointed responsible parties.

Do you calculate the waterfall and carried interest?

Work on the waterfall, carried interest and capital accounts may be scoped as accounting work for an eligible entity. The engagement letter specifies the accepted data, calculations and reconciliations. They do not replace validation of investor entitlements or distributions by the appointed parties.

Are you the fund's auditor?

No. A fund’s statutory audit is reserved to the approved statutory auditor. Financial Services Luxembourg prepares only the accounts and audit inputs for entities covered by its accepted accounting engagement and liaises with the appointed auditor. Preparing documents and coordinating do not constitute audit or certification.

How do you coordinate with the AIFM and depositary?

We provide accounting data and supporting documents agreed with the AIFM, administrator and depositary within the accepted engagement. Valuation, official NAV calculation and regulatory reporting remain the responsibility of authorised parties under the legislation and mandates. Coordination is documented without treating data delivery as the performance of a regulated function.

Is Financial Services Luxembourg an expert-comptable?

Financial Services Luxembourg is a licensed accountant (authorisation 10077274, RCS B213987), subject to AED supervision for AML/CFT purposes. The "expert-comptable" title is a regulated title held by members of the Ordre des Experts-Comptables; for engagements that specifically require it, or for the statutory audit, we work with the duly qualified professionals while remaining your single point of contact for fund accounting.

How much does fund accounting cost at Financial Services Luxembourg?

Pricing is on a quote basis, as the cost depends on the vehicle type, portfolio complexity, the number of investors and the NAV calculation frequency. After a precise scoping of your fund and its deadlines, we provide a tailored proposal, with no hidden cost. First reply within 24 working hours, firm quote within 48 working hours of scoping.
