The Trustee
Pension Master Trusts have a board of Trustees who have various legal duties, including making sure the pension scheme is run in the best interests of its members. At SEI, we refer to our Trustee board as ‘the Trustee’. The Trustee and our staff provide a high quality, affordable service that offers choice and flexibility not commonly seen in pensions.
Meet the Trustee
The Trustee is a corporate trustee (SEI Trustees Limited) to which individual Trustee Directors are appointed. SEI Trustees Limited has been the Trustee of the SEI Master Trust since 2007. We’re pleased to introduce the current Trustee Directors.
