An investment trust is a form of collective investment found mostly in the United Kingdom. Investment trusts are closed-end funds and are constituted as public limited companies. In many respects, the investment trust was the progenitor of the investment company in the U.S.The name is somewhat misleading, given that (according to law) an investment "trust" is not in fact a "trust" in the legal sense at all, but a separate legal person or a company. This matters for the fiduciary duties owed by the board of directors and the equitable ownership of the fund's assets.
In the United Kingdom, the term "investment trust" has a strict meaning under tax law. However, the term is more commonly used within the UK to include any closed-ended investment company, including venture capital trusts (VCTs). The Association of Investment Companies is the trade association representing investment trusts and VCTs.
