127.Section 37(1) provides that the new statutory powers of investment, acquisition of land and to appoint agents, nominees and custodians in Parts II – IV of the Act do not apply to trustees of authorised unit trusts. An authorised unit trust is a unit trust scheme declared by order of the Secretary of State to be such for the purposes of the Financial Services Act 1986 (Financial Services Act 1986 section 207(1)). A unit trust scheme is a collective investment scheme under which the property in question is held on trust for the participants (Financial Services Act 1986 section 75(8)). A collective investment scheme is broadly speaking an arrangement with respect to any property which is intended to enable the persons taking part to participate in or receive profits or income arising from the acquisition, holding, management or disposal of the property or sums paid out of such profits or income (Financial Services Act 1986 section 75(1)). The Secretary of State will only issue an order declaring a unit trust to be an authorised unit trust if he is satisfied that the scheme and, in particular, the trust deed complies with the requirements of regulations made as to – amongst other matters – the powers and duties of the manager and the trustee of the scheme (Financial Services Act 1986 sections 78 and 81). Authorised unit trusts therefore have no need of the new powers conferred by Parts II – IV of the Act. An authorisation order under section 78 of the Financial Services Act 1986 Act can be revoked under section 79 of that Act.
