When placing an order on their PEA, one enters the ISIN code of Unibail-Rodamco-Westfield, and the broker refuses the transaction. The message is terse: security not eligible. For a company listed on the CAC 40, this situation is surprising. It is explained by a combination of fiscal and legal barriers that the merger with Westfield in 2018 has made almost irreversible.
The SIIC status, the first barrier against the PEA for Unibail
The equity savings plan reserves its tax envelope for companies subject to corporate tax under common law conditions. Unibail-Rodamco-Westfield falls under the regime of Listed Real Estate Investment Companies (SIIC), a system that exempts the real estate company from corporate tax on the portion of its profits distributed as mandatory dividends.

This derogatory regime places URW outside the fiscal perimeter of the PEA. The AMF, in its recommendation position DOC-2018-12 (updated in June 2024), equates most listed real estate companies to fiscally transparent vehicles in regard to the PEA. Therefore, the administration and financial intermediaries have been treating URW shares as ineligible securities uniformly since 2025.
The Council of State has also confirmed this strict interpretation in a ruling dated February 22, 2024 (decision no. 470306). Even though the case concerned an energy company, tax experts now cite this jurisprudence to justify the lasting exclusion of securities subject to a derogatory regime similar to that of the SIIC. It is clear why including Unibail shares in a PEA remains impossible despite its presence in the CAC 40 index.

Westfield merger and headquarters in the Netherlands: the additional layer
Before June 2018, the former Unibail-Rodamco share (code FR0000124711) was a company under French law. The merger with the Australian group Westfield changed everything. On June 4, 2018, the former share disappeared, and a new security appeared: Unibail-Rodamco-Westfield NV, registered in the Netherlands and simultaneously listed on Euronext Amsterdam and Euronext Paris.
The head office is located in Amsterdam. The PEA accepts companies whose headquarters are in the European Union, so the Dutch domicile does not pose a problem in itself. The real blockage comes from the combination: Dutch headquarters plus derogatory tax regime distance URW from eligibility criteria on two simultaneous axes.
The mechanism of dual shares
The restructuring created a setup known as “twin action” or dual shares. A significant portion of the distributed income comes from subsidiaries and OPCIs not subject to corporate tax. The URW memo for PEA shareholders, updated in 2025, specifies that this architecture makes the security incompatible with the rules of the equity savings plan.
In practice, one faces a group with two legal heads whose revenue flows largely escape common French tax law. Brokers have no margin for interpretation: the security is blocked upstream by eligibility filters.
Practical consequences for PEA holders
If you hold old Unibail-Rodamco shares purchased before the merger, the situation has varied depending on the broker. Some have automatically withdrawn the shares from the PEA upon conversion. Others temporarily left the shares in the envelope, creating a regulatory gray area. Since then, most intermediaries have regularized the situation.
For investors wishing to hold URW today, the options boil down to a few alternatives:
- An ordinary securities account, which allows the purchase of URW shares without restriction but subjects dividends and capital gains to the standard tax scale (flat tax or progressive tax scale)
- A life insurance contract in units of account, with some insurers offering supports that include listed real estate companies, with favorable taxation beyond eight years of holding
- Sector-specific real estate ETFs eligible for the PEA, which replicate a basket of European real estate companies but do not include URW directly due to its ineligibility
The dividend yield of URW remains attractive to many investors, which explains the recurring frustration surrounding this exclusion from the PEA.
PEA-eligible real estate ETFs: a real alternative to Unibail?
Several ETFs replicating European real estate indices are housed in PEA envelopes. They do not offer direct exposure to URW but allow capturing the performance of the publicly traded real estate sector in Europe with the tax advantage of the equity savings plan.
The limitation of these ETFs lies in their composition. URW has a significant weight in European real estate indices, and its absence from a PEA-eligible ETF alters the risk and return profile of the product. One does not achieve the same exposure as holding the security directly in a securities account.
Check eligibility before placing an order
Before buying a stock or an ETF in a PEA, checking the ISIN code with your broker remains the most reliable method. Automatic filters are not infallible (feedback on this point varies across platforms), and some updates to reference databases can create temporary discrepancies.
The exclusion of Unibail from the PEA is neither a technical bug nor an arbitrary decision. It results from a derogatory tax regime (SIIC), a legal restructuring post-Westfield, and a jurisprudence that locks in the strict interpretation of eligibility criteria. As long as the group maintains this status, the situation will not change.
