On Wednesday, the U.S. Securities and Exchange Commission published proposed Regulation MC under the Securities Exchange Act of 1934, intended to mitigate conflicts of interest for security-based swap clearing agencies, security-based swap execution facilities and national securities exchanges that post or make available for trading security-based swaps. Under proposed Regulation MC, the agencies, facilities and exchanges noted above would be required to adopt ownership and voting limitations as well as certain governance requirements. Comments are being accepted by the SEC for 30 days after the date of the proposal's publication in the Federal Register.

The SEC also adopted an interim final rule requiring that security-based swap transactions that were entered into before the July 21, 2010 signing of the Dodd-Frank Act (and which had not expired as of that date) be reported to the SEC or a registered security-based swap data repository. According to SEC Chairman Mary Schapiro, "[t]his interim final rule provides a means for the Commission to gain a better understanding of the security-based swap markets, including their size and scope".
