The SEC issued a proposal to amend its requirements relating to rule changes requested by self-regulatory organizations (SROs), such as the securities and commodities exchanges ( www.sec.gov/rules/proposed/34-49505.htm ). The proposal aims to modernize and increase the efficiency of the rule-filing process by requiring SROs to submit recommended changes to the commission only in electronic form and to post all proposed modifications—as well as current and complete sets of their rules—on their Web sites. Comments are due June 4.
