New FINRA TRACE Symbols for GNMB Bonds

July 23, 2012

On Monday July 30, 2012, as part of data maintenance, FINRA will update the FINRA TRACE symbol for approximately 30,000 Agency Pass-Through Mortgage Backed securities (MBS) Ginnie Mae securities. As a result, these Ginnie Mae II TRACE symbols (GNMB) will be converted to GNMA. This change will ensure consistent base issuer symbols for these Ginnie Mae securities.

Please note, as is currently the case, the security will be indicated as Ginnie Mae I or Ginnie Mae II in the Security Description field. Current GNMA symbols will not be affected by this change.

Because of the very large number of securities affected by this change this event will not be available via the Securitized Products Daily List. Users are encouraged to download the Securitized Products Security Master Files in order to process the changes to the affected securities.

Please contact FINRA Product Management or call (866) 899-2107 with questions about this notice.
