Investment Advisory Committee

The function of the Investment Advisory Committee (IAC) is to provide an independent source of views on market developments. The IAC meets quarterly to broadly assess developments in and around financial markets and evaluate their potential impact on asset allocation and strategy over the medium and the long term. The IAC also challenges the team by asking questions, playing devil’s advocate and suggesting areas that could be further developed to better serve clients.

The IAC is composed of both internal and external members. External members are nominated to one-year terms. Currently, John Shakeshaft has the chairmanship, Martin Pereboom and Joost Rietvelt are members of the committee. Corestone’s CIO Paul van Gent and Head of Research Sadruddin Rejeb represent the investment team of the company.
