Collective Investment Trusts
A Collective Investment Trust (CIT) is a pooled group of trust accounts operated by a trust company or a bank. Collective Investment Trusts combine the assets of various individuals and organizations to create a larger, well-diversified portfolio.  Many individual employees encounter CITs through their investment in employer provided contributory retirement plans. There are two types of CITs:
- A1 Fund: A fund of grouped assets contributed by either the holding bank or affiliated banks for the exclusive purpose of investment and reinvestment. These funds are usually called Collective Investment Funds.
- A2 Fund: A fund of grouped assets contributed by pension, profit sharing, retirement, or other trusts that are exempt from federal income tax. This is the plan type that most employees encounter.
