The Equity Markets and Trading Committee of SIFMA provides comments to the Securities and Exchange Commission on proposed rule changes relating to New York Stock Exchange (NYSE) Rule 409(f),  Release No. 34-57045, File No. SR-FINRA-2007-037; Release No. 34-57046, File No. SR-NYSE-2007-118.  The proposed changes would delete the requirement that certain confirmations and correspondence reports include the name of the securities market on which the transaction is effected.  SIFMA fully supports the deletion of this requirement in light of new trading requirements under Regulation NMS and the operational challenges posed by such requirements for firms in having to capture the required information.
