The Federal Deposit Insurance Corporation (FDIC) acted as the Receiver for certain insured banks, handling the closure and asset liquidation of these institutions. The FDIC has completed its duties, distributed necessary dividends, and subsequently appointed FDIC-Corporate to handle any remaining documentation. As of the listed termination dates, the receiverships are officially closed, and the entities no longer exist legally. This action is backed by the authority of U.S. law.
Simple Explanation
The FDIC, like a caretaker for banks that couldn't keep going, has finished its job of closing them down and handling their left-behind stuff, so now there's nothing left for these banks to do. They have given the job of looking after any leftover paperwork to another part of FDIC, meaning these banks are like toys that got put away and don't get to play anymore.
