The Association of Investment Companies (AIC) is an organization that was established in 1932 with the goal of representing investment trusts, which are the oldest form of collective investment. Today, the AIC represents a wide range of investment companies, investment trusts, VCTs, and other closed-ended funds. The AIC aims to ensure that closed-ended investment companies are understood and considered by every investor.

The AIC provides extensive support to their members through regulatory and lobbying work, offering information and resources to member company directors. They also assist investors by providing information, research, and tools to help them make informed decisions when utilizing closed-ended investment companies in their portfolios.

Additionally, the AIC promotes their members to investors through various means, such as communications work, training activities, and their website. Through events, newsletters, and other communications, the AIC engages with both their members and investors. They facilitate connections between members and investors, and also work with platforms and advisors to provide information and training.

Furthermore, the AIC engages with the wider financial community through industry participation, working groups, and lobbying efforts.
