What it means
European investors buy funds built as companies with a special power: their capital breathes. The SICAV, an investment company with variable capital, issues and redeems its own shares continuously at asset value.
The variable capital is the point: unlike a normal company, a SICAV needs no formalities to grow or shrink its share count, so the fund simply prints new shares for buyers and cancels them for sellers. Luxembourg built its fund industry on the form: the CSSF-published law on undertakings for collective investment defines the SICAV among the vehicles it licenses, alongside the contractual fund, the FCP.
The structure pairs with UCITS: a SICAV authorised under the UCITS directive can be sold across the European Union on a single passport, which is why Luxembourg and Dublin became the world's fund factories. Governance follows company law: shareholders elect a board, the board appoints the manager and custodian, and the custody rule, assets held by an independent depositary, is the investor's structural protection.
The sub-fund architecture multiplies the efficiency: one SICAV can host dozens of umbrella sub-funds, each with its own strategy and currency, sharing one legal shell and one set of service providers. For the investor the experience is simple: buy and sell at net asset value on dealing days, with the company itself, not a market maker, standing on the other side of every trade.
For a non-finance reader, a SICAV is a company whose only business is holding your investments, sized automatically to exactly what its shareholders have put in. The cross-border business is the industry's scale secret: funds domiciled in Luxembourg and Ireland are distributed worldwide, and the SICAV form's familiarity reassures regulators and platforms from Singapore to Santiago.
Costs concentrate where the structure allows: one depositary, one administrator, and one auditor can serve an entire umbrella, which is why sub-funds are the cheapest way to launch a strategy in Europe. The governance question survives the plumbing: a board that oversees dozens of sub-funds must police conflicts across them, and the independence of directors is the discipline that keeps the shell honest.
In practice
Real-world examples.
Example
A manager passports one Luxembourg SICAV across the EU, hosting three bond strategies as sub-funds of a single shell. Each sub-fund has its own investment policy and currency. The manager files one set of corporate and regulatory documents instead of three.
Example
Shares are created and cancelled at net asset value daily, with capital adjusting automatically to flows. An investor in Milan subscribes on Monday and a pension fund redeems on Tuesday, both at the dealing-day price. No board resolution is needed for either trade.
Example
An independent depositary holds the portfolio, separating the assets from the manager's own fate. If the manager were to fail, the securities would still sit with the depositary in the fund's name. Investors can see the depositary named in the fund's prospectus.
Formula
Calculation
Net asset value per share = (Sub-fund assets - Sub-fund liabilities) / Shares in issue. The mechanics: shares are issued and redeemed at net asset value per share on dealing dates, capital varies automatically with flows, and umbrella structures segregate assets and liabilities by sub-fund.
Worked example with fictional figures. A bond sub-fund holds assets of $52,000,000 and has liabilities of $2,000,000, so net assets are $50,000,000. With 5,000,000 shares in issue, net asset value per share is $50,000,000 / 5,000,000 = $10.00.
An investor subscribes $1,000,000. The SICAV issues $1,000,000 / $10.00 = 100,000 new shares, so net assets rise to $51,000,000 and shares in issue rise to 5,100,000. Net asset value per share is still $51,000,000 / 5,100,000 = $10.00.
Another investor then redeems 200,000 shares and receives 200,000 x $10.00 = $2,000,000. Net assets fall to $49,000,000, shares in issue fall to 4,900,000, and net asset value per share remains $49,000,000 / 4,900,000 = $10.00. The flows changed the size of the fund, not the price per share, which is why the capital is called variable. Fees and dealing charges would adjust the amounts in practice.Case study
Seen in the real world.
This case study is fictional and illustrative. A made-up London asset manager wants to sell its bond strategies to clients in Paris, Milan, and Madrid. Its lawyers present the standard map: a Luxembourg SICAV with an umbrella of three sub-funds, UCITS-authorised, passported across the Union on one approval. The mechanics charm the operations team: a Milanese investor's subscription creates new shares at that day's net asset value, a redemption the following month cancels shares the same way, and no board resolution, filing, or capital-change formality ever interrupts the flow.
The custody structure answers the compliance question before it is asked: the portfolio sits with an independent depositary bank, legally separate from the manager, so the SICAV's failure would strand the manager but not the assets. Five years on, the manager's retrospective counts the structure's quiet wins: one legal vehicle hosts strategies it could never have afforded to register separately, and the passport turned European expansion from a legal project into a sales one. The general counsel's summary enters the firm's playbook: the SICAV is boring corporate plumbing that behaves like infrastructure, and the day you stop noticing your fund structure is the day you chose it well.
Watch out
Common mistakes.
- Confusing it with a closed-end fund; a SICAV issues and cancels shares at NAV, so no premium or discount to asset value arises.
- Assuming one fund per company; umbrella SICAVs host many sub-funds, and the segregation between them is the feature, not an accident.
- Overlooking the depositary; investor protection rests on independent custody, and the manager never holds the assets itself.
