The Securities and Exchange Commission ("Commission") is adopting rule amendments that require self-regulatory organizations ("SROs") to file proposed rule changes electronically with the Commission, rather than in paper form. In addition, the Commission is requiring SROs to post all proposed rule changes, as well as current and complete sets of their rules, on their Web sites. The Commission is also requiring all participants in National Market System Plans ("NMS Plans") to arrange for posting on a designated Web site a current and complete version of the NMS Plan. Finally, the Commission is making certain technical amendments to the requirements for SRO rule changes. Together, the amendments are designed to modernize the SRO rule filing process by making it more efficient and cost effective. The amendments also should improve the transparency of the rule filing process and assure that all SRO members and other interested persons have ready access to an accurate, up-to-date version of SRO rules.
