On October 9, the SEC announced publication of a Risk Alert and FAQs to remind broker-dealers of their obligations when they engage in unregistered transactions on behalf of their customers. The publication of the staff guidance was accompanied by the announcement of an enforcement action against two firms for improperly selling billions of shares of penny stocks through such unregistered offerings. The Risk Alert summarizes deficiencies that were discovered by the SEC’s Office of Compliance Inspections and Examinations (OCIE) during a targeted sweep of 22 broker-dealers frequently involved in the sale of microcap securities.
