What is EMMA?

in the municipal securities market. EMMA provides investors with key information
about municipal securities, free of charge. The information on EMMA is presented
in a manner specifically tailored for retail, non-professional investors who may

What Documents and Data Are Available On EMMA?
EMMA houses 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 college savings plans 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 their debt at
a lower interest rate), and 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, are available
on EMMA as well.
All of the documents and data on EMMA are accessible in an integrated display that
provides comprehensive information for each municipal security. For more information about finding documents and data on EMMA, click on the links below.

What is the MSRB?
EMMA is a service of the MSRB, the self-regulatory organization that protects investors, issuers of municipal securities and entities whose credit stands behind municipal securities, and public pension plans by promoting a fair and efficient municipal market. The MSRB fulfills this mission by regulating securities firms, banks and municipal advisors that engage in municipal securities and advisory activities. The MSRB has operated under Congressional mandate with oversight by the Securities and Exchange Commission since 1975.
The MSRB collaborates with the Securities and Exchange Commission, Financial Industry Regulatory Authority, Federal Deposit Insurance Corporation, Federal Reserve System, and Office of the Comptroller of the Currency, all of which enforce compliance with MSRB rules among brokers, dealers, municipal advisors and banks.
