This Practice Note examines the key regulatory requirements to consider when changing the trustee of an authorised unit trust (AUT), including the procedure for changing the trustee, the process for selecting a new trustee, and the related disclosure and notification requirements. For the purposes of the Financial Conduct Authority (FCA) Handbook, ‘depositary’, in relation to an AUT, means the trustee. What is an authorised unit trust An AUT is a type of investment fund and, pursuant to section 237(3) of the Financial Services and Markets Act 2000 (FSMA 2000), a unit trust scheme which is authorised by an order in force under section 243 of FSMA 2000. An AUT may be a undertaking for the collective investment of transferable securities (UCITS), a non-UCITS retail scheme (NURS), a qualified investor scheme (QIS), a long–term asset fund (LTAF) or a charity authorised investment fund. In certain respects, the FCA’s rules in relation to AUTs differ depending on its classification. For more information, see Practice Note: Authorised unit trusts (AUTs)—What is an AUT? Changing
