On March 7, the Financial Industry Regulatory Authority published Regulatory Notice 18-09, which expands the criteria FINRA will use to designate member firms that must participate in business continuity and disaster recovery testing (BC/DR testing). Regulation SCI requires FINRA to designate firms that must participate in BC/DR testing.  Regulatory Notice 18-09 indicates that the following firms must engage in BC/DR testing: firms that account for at least 5 percent or more of the average dollar volume of Treasury securities reported to the Trade Reporting and Compliance Engine (TRACE) over the six-month period preceding the designation (provided that the cumulative dollar volume represented by all such firms amounts to at least 50 percent of all dollar volume in Treasury securities reported to TRACE during the applicable six-month period).  The Regulatory Notice indicates that FINRA expects to make designations in April and that testing will occur in October.
