Plan d’Epargne pour la Retraite Collectif (PERCO) account
Collective pension savings scheme which allows the employees of a company or group of companies to save, in some cases with help from their employer, by investing in transferable securities. Employees enjoy favourable tax treatment in exchange for their savings being blocked, generally until the retirement age. The sums paid are therefore blocked until the employee retires, barring exceptional circumstances explicitly provided by law.
