On October 1st, the SEC provided notice of the Municipal Securities Rulemaking Board's filing of a proposed amendment to MSRB Rule G-47, on time of trade disclosure obligations, proposed revisions to MSRB Rule G-19, on suitability of recommendations and transactions, proposed MSRB Rules D-15 and G-48, on sophisticated municipal market professionals, and the proposed deletion of interpretive guidance. The changes would consolidate guidance and harmonize Rule G-19 with the Financial Industry Regulatory Authority's suitability rule. Comments should be submitted within 21 days after publication in the Federal Register, which is expected shortly. SEC Release No. 34-70593.
