Automated Customer Account Transfer
The transfer of securities from one account to another at a separate bank or brokerage. This may be done for any security or derivative: stocks, bonds, options, and futures may all be transferred via ACAT. However, each ACAT occurs over the Automated Customer Account Transfer System, which is only open to institutions eligible for membership in the National Securities Clearing Corporation and member banks of the Depository Trust Company.
