Automated Customer Account Transfer Service (ACATS)

ACATS automates the transfer of securities and account assets between U.S. brokerage firms.

The Automated Customer Account Transfer Service (ACATS) is a system designed to facilitate the seamless transfer of securities such as stocks, bonds, mutual funds, and options from one brokerage firm to another. Managed by the National Securities Clearing Corporation (NSCC), ACATS ensures a streamlined process for transferring customer accounts in a standardized and automated manner.

How ACATS Works

The ACATS system uses specific protocols to coordinate the transfer of assets. The process generally involves:

  • Initiation of Transfer: The customer requests the transfer through the receiving brokerage.
  • Validation: The receiving brokerage submits the transfer request to the sending brokerage.
  • Processing: Both brokerages reconcile the account details and validate holdings.
  • Transfer Completion: The securities and funds are moved to the customer’s account at the receiving brokerage.

Types of Transfers in ACATS

  • Full Transfers: Moving all account holdings from the current brokerage to a new one.
  • Partial Transfers: Moving specific assets or positions while leaving the rest intact with the current brokerage.

Transfer Timetable

ACATS typically completes transfers within six business days, though the duration may vary based on the complexities involved, such as the types of securities and the responsiveness of the brokerages.

Account Reconciliation

Both the sending and receiving brokerages perform meticulous account reconciliations to ensure all securities are accurately transferred, accounting for dividends, interest, or any pending transactions.

Individual Investors

Consider an individual investor who wishes to move their investment portfolio from one brokerage to another to take advantage of better service or lower fees:

  • Stocks and Bonds: Directly moved without needing to sell and repurchase, preserving the investor’s positions.
  • Mutual Funds and Options: Transferred efficiently, maintaining holdings.
