Dutch trust office TMF Group has put itself up for sale, the Financieele Dagblad says on Friday.

TMF says in a small note on its website that it has brought in Goldman Sachs to look at ‘strategic options, which could include a sale or stock exchange listing’.

This means that four of the five top Dutch trust offices will have changed hands in a short length of time, the FD says. Last year Intertrust was floated and Orangefield and SGG were sold to foreign players. Number 5, Citco, is still owned by the Smeets family.

Trust offices manage the affairs of multinational companies and rich private individuals and have a central role in developing corporate tax evasion strategies by dealing with the paperwork on behalf of international conglomerates to establish and administer letterbox companies.

The number of Dutch letterbox firms – so called because they only exist on paper – rose 17% to 14,425 over the past two years, the Volkskrant said last October.

Meanwhile, the NRC reports that Citco has rejected an invitation by the parliamentary finance committee to attend a special hearing on the Dutch trust sector. TMF and Intertrust are both sending their chief executives to the Netherlands to be questioned by MPs.
