- Liquidity Pool: this is the "main pool" in CRIS, and the one courts most commonly use. As the name suggests, it is the most liquid of the pools (though all pools are managed to have sufficient daily liquidity).
- Minors' Pool: this pool is used specifically for cases where funds are being held on behalf of an adjudicated minor's case. Since such funds are often held for a year or more, this pool holds longer-duration Treasuries than the Liquidity Pool. Minors' cases may also be deposited in the Liquidity Pool, depending on the court's preference.
- Disputed Ownership Fund (DOF) Pool: this pool is specifically for 28 U.S.C. Section 1335 interpleader cases, where the owner of the funds is undetermined. The IRS requires that quarterly taxes be withheld and remitted on the interest earned in such cases. This pool relieves courts of the obligation to appoint a tax administrator for cases deposited in the pool, as taxes are withheld prior to earnings being allocated to the cases. Note that 28 U.S.C. Section 1335 interpleader cases that have certain types of payments, other than attorney's filing fees, would need to have a tax administrator appointed and be deposited in the Liquidity Pool.
