Automated Customer Account Transfer Service (ACATS)

0.00 ( 0 votes )


The Automated Customer Account Transfer Service (ACATS) system automates and standardizes procedures for the transfer of assets in a customer account from one broker-dealer and/or bank to another. ACATS also has an interface with NSCC’s Fund/SERV that facilitates the transfer of mutual fund assets between two broker-dealers, or a broker-dealer and a fund company.

ACATS enables participants to efficiently and automatically enter, review, and generate instructions to settle the transfer of customer accounts. ACATS facilitates the transfer of many different types of assets, including equities, corporate and municipal bonds, unit investment trusts, mutual funds, options, annuities, and cash.

ACATS transactions are not guaranteed, and therefore are subject to reversal in the event of the default of a participant that is party to a transfer.

All qualified NSCC full service Members and DTC bank participants are eligible to use ACATS. Mutual Fund Service Members of NSCC are eligible to use the service on a limited basis, through the interface between ACATS and Fund/SERV.
