The Investment Association is the trade body that represents UK investment managers. They claim to have 200 corporate members which collectively manage over £5.7 trillion on behalf of clients in the UK and around the world.
In 2015, the trade body Investment Management Association was renamed the Investment Association, following the merger between the IMA and the Investment Affairs division of the Association of British Insurers. The IMA was established in 2002 after a merger of the Association of Unit Trust and Investment Funds (AUTIF) and the Fund Managers Association. AUTIF, before 1993, was itself known as the Unit Trust Association and was established in 1959.
