APG, the €424bn asset manager for Dutch civil service pension fund ABP, has announced that chief executive Dick Sluimers is to resign next year.

Sluimers, who is 62 years old, has served for 25 years at ABP and APG, where he has been chief executive since 2008.

He said it was a “natural time” to step down, as the reorganisation programme at APG, kicked off in 2012, was now nearing its conclusion.

After he resigns, Sluimers said he would dedicate himself to various advisory and management activities.

He is already a member of the board of directors at AkzoNobel and Atradius/Atradius Credit Insurance, among other positions.

APG has not yet decided who Sluimers’s successor will be.

Sources at Dutch financial new daily FD and IPE sister publication Pensioen Pro have mooted Angelien Kemna, chief finance and risk officer at APG, as a possible successor.

Roderick Munsters, who recently stepped down as chief executive at Robeco, and who was CIO at APG between 2005 and 2009, was also mentioned by FD sources.

APG is administrator and asset manager for ABP, the Dutch pension fund for government workers, as well as several other Dutch pension funds, including those for construction workers, cleaners and housing associations.

It manages €417bn in assets for 4.5m pension fund participants.
