The ICAV Act — Irish Collective Asset-management Vehicles Act 2015
The ICAV is Ireland's bespoke corporate fund vehicle — a body corporate with variable capital that is registered and regulated by the Central Bank of Ireland, not the Companies Registration Office. It can be authorised as a UCITS or an AIF, and — the point that made it — it can elect US "check-the-box" treatment that the older plc investment company could not. Sponsors pick it because it sits outside most of the Companies Act plumbing built for trading companies, and because a US-taxable investor base can treat it as a partnership or disregarded entity rather than a foreign corporation.
Scope and the core mechanism
The ICAV Act 2015 creates a standalone corporate form for collective investment. An ICAV is not a company incorporated under the Companies Act 2014 — it is a distinct body corporate that comes into existence when the Central Bank of Ireland registers it. The Central Bank confirms this dual role explicitly: it acts as registrar for ICAVs (the incorporation step introduced in March 2015), and that "the registrar function of the Central Bank is a separate function to the authorisation process." Once registered, an ICAV that is an AIF is authorised under the ICAV Act itself; an ICAV that is a UCITS is authorised under the European Communities (UCITS) Regulations 2011. So the same body registers the vehicle and regulates the fund — one door, two functions.
The defining feature is variable capital: the ICAV issues and redeems shares at net asset value (NAV), so its share capital always equals the value of its assets. This dispenses with the company-law machinery around maintenance of capital — share premium, capital reduction procedures, distributable-reserves tests — that is irrelevant to an open-ended fund but expensive to comply with. It can be structured as a single fund or as an umbrella with multiple sub-funds under one legal entity.
Key provisions
| Provision | What it says | The practical point |
|---|---|---|
| Registration by the Central Bank | An ICAV is incorporated on registration by the Central Bank of Ireland, which maintains a public Register of Registered ICAVs and a Register of Charges. | Your incorporator is your regulator. No CRO filing, no separate company-registry track — the fund authority owns the corporate lifecycle. |
| Variable capital (shares at NAV) | Share capital equals NAV at all times; shares are issued and redeemed to reflect the value of assets under management. | Subscriptions and redemptions happen without capital-maintenance friction — no capital-reduction court process to shrink the fund. |
| UCITS or AIF | The same corporate form can be authorised as a UCITS or as an AIF, on separate authorisation tracks after registration. | One vehicle type covers both retail (UCITS) and alternative (AIF) strategies — you choose the product regime, not the entity type. |
| Segregated-liability umbrella | An ICAV may be an umbrella with sub-funds; the Act provides for segregation of liability between sub-funds (exact section — see To verify). | A creditor of one sub-fund cannot, in principle, reach the assets of another — the "ring-fence" that lets one platform host unrelated strategies. |
| Dis-application of company-law rules | The ICAV is not subject to much of the Companies Act apparatus built for trading companies — e.g. an ICAV can dispense with the requirement to hold an annual general meeting, and is not required to spread investment risk at the entity level the way a plc investment company is. | Lower ongoing admin. Fewer mandatory meetings, no entity-level diversification rule bolted on top of the fund's own investment restrictions. |
| US check-the-box classification | An ICAV is an "eligible entity" for US federal tax purposes and can elect to be treated as a partnership (or a disregarded entity if single-shareholder) rather than a corporation (US mechanics — see To verify). | US-taxable investors can get flow-through treatment, avoiding a layer of entity-level tax — the single biggest reason the ICAV displaced the plc for US-facing funds. |
Amendment history
| Date | Instrument | What changed |
|---|---|---|
| 2015 | Irish Collective Asset-management Vehicles Act 2015 (No. 2 of 2015) | Original Act — created the ICAV and the Central Bank's registrar function (commenced March 2015). |
| 2020 | Investment Limited Partnerships (Amendment) Act 2020 | Amended the ICAV Act among other funds legislation (precise ICAV Act sections amended — see To verify). |
| Later SIs | Various statutory instruments (see To verify) | Consult the Law Reform Commission revised Act for the consolidated, up-to-date text with annotations. |
What it works with
The ICAV is the container; the product regime and manager rules sit on top. Its most common alternative-fund form is the QIAIF — a Qualifying Investor AIF housed in an ICAV is the workhorse Irish private-funds structure. The partnership alternative is the ILP (Investment Limited Partnership), which the 2020 Act modernised and which suits closed-ended private-equity and credit strategies where LPs want a partnership rather than a corporate. When an ICAV is an AIF, its manager sits under AIFMD — the ICAV Act governs the vehicle, AIFMD governs the AIFM running it. ICAVs are a standard wrapper for loan-originating funds, and feature in any domicile comparison against Luxembourg's SICAV/RAIF. For managers below the AIFMD thresholds, see sub-threshold AIFM for how the lighter regime interacts with the vehicle.
The gotcha: "it's just a company" is the trap. Because the ICAV was deliberately carved out of the Companies Act, your company-law instincts mislead — there is no CRO, the constitutional document and its amendment mechanics follow the ICAV Act (not Companies Act) rules, and the Central Bank is both registrar and regulator, so corporate changes can carry a fund-authorisation dimension a plain company wouldn't. Separately, the check-the-box advantage is only an advantage if the US election is made correctly and on time — treat it as a US tax filing with its own mechanics and deadlines, not a feature that switches on automatically because you chose an ICAV.
To verify
- US check-the-box mechanics — that the ICAV is an "eligible entity" and the election/timing rules (Form 8832; default classification; deadline relative to the entity's first relevant US tax year). Confirm against IRS entity-classification guidance and current US tax advice — this page states the mechanism, not the current filing specifics.
- Segregated-liability section — the precise section of the ICAV Act 2015 providing segregation of liability between sub-funds, and any limits on it. Confirm against the revised Act.
- AGM dispensation and entity-level risk-spreading — the exact ICAV Act sections that allow an ICAV to dispense with the AGM and that disapply the plc-style risk-spreading requirement. Confirm section numbers against the Act text.
- Amendment detail — which ICAV Act sections the Investment Limited Partnerships (Amendment) Act 2020 amended, and any later statutory instruments. Confirm against the Law Reform Commission consolidated text.
