The SEC designated EMMA as the official repository for municipal securities disclosures in 2009. The SEC oversees the MSRB. The MSRB is a self-regulatory organization whose mission is to protect investors, state and local governments and other municipal entities, and the public interest by promoting a fair and efficient municipal securities market. Neither the SEC nor the MSRB review the disclosure documents prior to their posting on EMMA. [1]
