SEC Extends Broker-Dealer Responsibility Rule Comment Period a Month. The Securities and Exchange Commission has extended until June 18 the comment period for its Amendments to Financial Responsibility Rules for Broker-Dealers. The proposed changes to Rule 15c3-3 and Rule 15c3-1 would allow large treasury money market funds to be used as special reserves and collateral for brokerage firms. The proposal also includes a dramatic increase in disclosure requirements for lower-yielding brokerage "sweep" accounts to banks. Commments to date may be seen here. Federated Investors, which spearheaded the money fund-related changes, and counsel Dechert LLPexpressed disappointment in the rules as currently written, saying, "Unfortunately, we believe that the proposed changes ... fall short of the needs of the marketplace."
