Record Types

The receiving firm enters the transfer instructions into the ACATS systems. When a mutual fund is involved, ACATS sends these instructions (via 018 records) to Fund/SERV. Fund/SERV then transmits the 018 records to the fund. These records provide the instructions of how to re-register the assets in a customer’s account held at that mutual fund.

The following are the record types used to communicate information between ACATS and Fund/SERV:
