On October 26th, the SEC provided notice of the Municipal Securities Rulemaking Board's filing of a proposed rule change amending Rule G-16, on periodic compliance examination, in order to permit the examination of brokers, dealers, and municipal securities dealers that are members of the Financial Industry Regulatory Authority at least once each four calendar years, rather than at least once each two calendar years as currently prescribed by Rule G-16. Further, the MSRB proposed a rule change consisting of amendments to Rule G-9, on preservation of records, which would require dealers to retain certain records for four years, rather than three years as currently prescribed by Rule G-9. Comments should be submitted on or before November 22, 2011. SEC Release No. 34-65631.
