DUFOUR is an investment foundation that serves the collective management and investment of the pension assets entrusted to it by pension funds. It is subject to the supervision of the Occupational Pension Supervisory Commission (OAK BV). DUFOUR sees itself as a platform for investment strategies with a real estate focus.
