Pension funds, foundations, Central 2nd-Pillar Office: who does what.

The Swiss occupational pension system looks like an archipelago: 1,380 active pension funds, ~340 vested benefits foundations, and a central supplementary institution that acts as a safety net. If you do not know who handles what, you do not know where to look when an asset disappears.

Overview: three institutions, three roles

1. The pension fund — your active years

This is the institution that collects your contributions every month while you are an employee. Three common variants:

• Employer fund — specific to a single company (typically the large ones: UBS, Nestlé, SBB, Roche…). Very organized, but inflexible: if you change employer, the money must leave.
• Branch or collective fund — covers several employers in the same sector (Swisscanto, Profond, Vita Joint Foundation…). Very common among SMEs.
• Public-law fund — for civil servants of a canton, municipality, or public institutions (CPEG in Geneva, BVK in Zurich…).

Whatever the type, the principle is the same: as long as you work for the affiliated employer, that fund holds your assets. When you leave, it has 6 months to transfer your assets to your new fund. If you have none, it transfers them to a vested benefits foundation that you specify.

2. The vested benefits foundation — the waiting room

A vested benefits foundation is a specialized body whose sole job is to hold LPP assets between two professional phases. There are about 340 in Switzerland, almost all tied to a bank or insurance company.

Three moments when your assets land there:

1. You leave a job without having another within 6 months.
2. You take a sabbatical or a long break without staying affiliated to your former fund.
3. You leave Switzerland for the EU/EFTA and the mandatory part of your LPP must remain in Switzerland (details here).

The foundation typically offers two products: a vested benefits account (savings, interest rate) or a policy (insurance with additional guarantees). We compare the two in our article account vs vested benefits policy.

3. The supplementary institution — the official safety net

The supplementary institution is unique in Switzerland. Officially called Stiftung Auffangeinrichtung BVG (Supplementary Institution LPP Foundation), it is headquartered in Zurich. It performs three functions:

1. Forced affiliation of employers who have not found a fund.
2. Default reception of orphan assets when an insured person gives no instruction when leaving their employer.
3. Lost-asset search service via the Central 2nd-Pillar Office (based in Berne), a centralized desk that queries all LPP actors in Switzerland.

According to Auffangeinrichtung BVG (2024 report), about CHF 6 billion sit dormant on ~950,000 contactless accounts. Not a marginal statistic.

The typical journey of an asset

Let's follow a fictional but representative journey:

1. 2014: Camille starts at Banque Cantonale Vaudoise. Contributions paid to the BCV Pension Fund.
2. 2017: Camille moves to Nestlé. Assets transferred to the Nestlé Pension Fund.
3. 2020: 18-month break for a personal project. Assets transferred to the Credit Suisse vested benefits foundation on Camille's instruction.
4. 2022: Back to work at Roche. Camille forgets to ask for the transfer from the CS foundation. The Roche Pension Fund opens a new account with the new contributions only.
5. 2025: Camille moves back to France. The Roche fund account is split: the mandatory part goes into vested benefits in Switzerland, the extra-mandatory part is paid out. But the CS account from 2020 still sleeps.

Three years later, in 2028, Camille will discover by chance this CS account she had forgotten. This is exactly what the Central 2nd-Pillar Office and the foundations let you find, provided you query them all.

How to tell them apart on your documents

Got a pension letter? To identify who it is:

• If the institution carries a company or branch name ("X Pension Fund", "Pensionskasse Y", "Z Collective Foundation"): it is a pension fund. You are there because you work (or worked) there.
• If the institution carries a bank name with "vested benefits" / "Freizügigkeit" in its title (e.g., "UBS Freizügigkeit Stiftung", "BCV Vested Benefits Foundation"): it is a vested benefits foundation. You have assets waiting there.
• If the institution is the "Auffangeinrichtung BVG" or the "Central 2nd-Pillar Office": it is the supplementary institution. This means your assets were placed there by default at some point — never a bad sign in itself, but often the sign of a step without instruction on your side.
