While historically,
unit trusts were favoured legal vehicles for investment, in the 1990s it was felt that the UK government should allow a corporate form that could repurchase its own shares without the standard restrictions in the
Companies Act. The
Open-Ended Investment Companies (Investment Companies with Variable Capital) Regulations 1996 first introduced the OEIC, on 11 November 1996 which came into force on 6 January 1997. They were enacted under the
European Communities Act 1972 section 2(1) and were therefore known as the "ECA Regulations". The Securities and Investment Board (predecessor to the
FCA) regulations, the
Financial Services (Open-Ended Investment Companies) Regulations 1997 were approved by the SIB Board on 16 January 1997 and came into effect as from that date. The first commercial OEIC was launched by
Threadneedle Asset Management in 1997. These regulations only allow investment in
transferable securities (e.g., listed securities, other
collective investment schemes, or
certificates of deposit). This ensured that OEICs fell within the scope of the
Undertakings for Collective Investment in Transferable Securities Directives (
UCITS). With the advent of a single regulator, the FSA, the previous regulations were replaced by the Open-Ended Investment Companies Regulations 2001 under the
Financial Services and Markets Act 2000 section 262. These changes brought the formation of OEICs under control of the FSA and removed the automatic inclusion of an ICVC under the UCITS directive allowing scope for non-UCITS investments (e.g., money market funds, property funds and funds of funds). The changes ensure a level playing field for unit trusts and OEICs. The FSA was split into two during 2013 and the FSA became the Financial Conduct Authority (FCA) for small and medium-sized firms with the Bank of England taking on responsibility for larger firms with systemic impact. ==Legal structure==
