The EMMA website is funded and operated by the Municipal Securities Rulemaking Board (MSRB), the self-regulatory organization charged by Congress with
promoting a fair and efficient municipal securities market. EMMA is designated by the U. S. Securities and Exchange Commission as the official source for
municipal securities data and disclosure documents. The website provides free public access to objective municipal market information and interactive
tools for investors, municipal entities and others. EMMA supports municipal market transparency but is not a platform for buying or selling bonds.
What is EMMA?
The EMMA website was established to increase the transparency of the municipal securities market by providing free public access to municipal securities
disclosures and data. EMMA provides investors, state and local governments and other market participants with key information and tools to put that
information into context. EMMA is an award-winning website, recognized by the National Federation of Municipal Analysts and the National Association
of State Treasurers' State Debt Management Network.

What Documents and Data Are Available on EMMA?
The SEC designated the EMMA website as the official repository for municipal securities disclosures in 2009. EMMA houses hundreds of thousands of
municipal disclosure documents that provide information for investors about municipal securities. These include offering documents, called official
statements, for most new offerings of municipal bonds, notes, 529 savings plans, ABLE programs and other municipal securities issued since 1990.
EMMA also provides access to advance refunding documents, which detail arrangements made when new bonds are issued to establish escrows to pay off
existing bonds (usually to refinance the old debt at a lower interest rate). Also available are continuing disclosure documents that describe material
information throughout the life of a bond and must be provided by municipal bond issuers. Additional disclosures that are voluntarily provided by
issuers may be available for some bonds.
EMMA also provides market transparency data, which includes real-time prices and yields at which bonds and notes are bought and sold, for most trades
occurring on or after January 31, 2005. Interest rates for municipal securities, including those for auction rate securities and variable rate demand
obligations, can be found on EMMA as well. Municipal market-wide trends and data are available in the market statistics section.
EMMA also provides free public access to market-wide information, including third-party yield curves and indices, a calendar of upcoming municipal
offerings scheduled to come to market and daily statistics on trading patterns. For more information about finding documents and data on EMMA, go to
the EMMA Help page.
