Fannie Mae Provides Date for Refinitiv Index Name Change in Single-Family MBS Disclosures

Effective March 25, 2024, Fannie Mae will replace the index name "Refinitiv USD IBOR Cash Fallback" with "FTSE USD IBOR Cash Fallback" in its Single-Family mortgage-backed security (MBS) disclosures. This update reflects the London Stock Exchange Group's (LSEG) decision to retire the Refinitiv brand, replacing "Refinitiv" with "FTSE" in its interest rate product names, as announced in 2023.

Beginning March 25, 2024, the following index name changes will be effective in Fannie Mae's Single-Family MBS disclosures. There will be no other changes to the management or administration of these products; Refinitiv continues to be the administrator for these rates and the RIC codes will remain the same. Additionally, Fannie will be updating its Single-Family ARM MBS Subtypes to reflect the new name. With the update to our subtypes on March 25, 2024, Fannie Mae will also be removing the individual files in text format (.txt) from its ARM MBS Subtype webpage; however, Subtype information will still be available in the .csv format.
