A new limited broker/dealer classification framework at the federal level has been created as the result of a recent SEC Order approving a FINRA rule proposal seeking to address the longstanding industry desire for augmented exemptive relief and/or limited registration classifications for broker/dealers that restrict their activities to certain designated corporate finance transactions. The new federal broker/dealer registration category known as Capital Acquisition Brokers (“CABs”), which some observers have dubbed a “lite” form of broker/dealer registration, is the latest development in this area of securities regulation, and follows a recent string of federal and state no-action letters providing exemptive relief to so-called Mergers and Acquisitions (“M&A”) Brokers. However, enthusiasm for the new CAB Rules should be tempered somewhat in that: (1) the CAB Rules do not provide exemptive relief—i.e., they do not allow firms to avoid registration but instead set up a form of registration that is meant to be somewhat less onerous; (2) CAB registration still requires that CAB firms adhere to many of the same strictures required of full broker/dealers; and (3) opting to be regulated as a CAB may require reassessment as time goes on to the extent that a firm’s business activities change. While formally approved by the SEC, FINRA’s CAB Rules are not as yet effective. FINRA will publish the effective date in an upcoming Regulatory Notice.
