Capital Acquisition Brokers

Capital Acquisition Brokers (CABs) are firms that engage in a limited range of activities, including: 

  • Advising companies and private equity funds on capital raising and corporate restructuring, and
  • Acting as placement agents for sales of unregistered securities to institutional investors under limited conditions.

Firms that elect to be governed under the CAB rule set are not permitted, among other things, to carry or maintain customer accounts, handle customers’ funds or securities, accept customers’ trading orders, or engage in proprietary trading or market-making.

Rule Book

The CAB rules become effective on April 14, 2017. In order to provide new CAB applicants with lead time to apply for FINRA membership and obtain the necessary qualifications and registrations, CAB Rules 101-125 will become effective on January 3, 2017. 


FINRA encourages qualifying member firms and new firms to consider converting to CAB status.  Switching to CAB status will help ensure that qualifying firms will be governed by a regulatory structure that is better suited to the limited nature of their business.

On January 3, 2017, FINRA will begin accepting applications for firms wishing to register as Capital Acquisition Brokers.  This includes:

  • firms that are not broker-dealers but wish to register as CABs, and
  • existing FINRA member firms wishing to elect CAB status.

To select CAB status, a current firm must contact its regulatory coordinator and request to change its Membership Agreement.  A new firm must file a New Membership Agreement.  In the membership agreement, firms must represent that their activities will be limited to those permitted for CABs and that they agree to comply with the CAB rules.  

Testing the waters?

Firms that currently operate as full-service broker-dealers may convert to CAB status and then return to their former status within a year if they prefer full-service status.  Firms that revert to full status within a year are not required to file a Continuing Membership Application.
