Beginning on September 7th (the 4th Business day of the month) at 7:30 PM, Ginnie Mae will begin publishing a new HMBS Supplemental file (named “HSuppl_YYYYMM.txt”) on the Disclosure Data Download
page. The purpose of this file is to provide data for current-period values for the Security Interest Rate for active, HMBS Fixed Rate “RF” Pool Type pools. The file will be provided in the Other
section on the Disclosure Data Download
page. The HMBS Supplemental file layout and sample file are attached for reference.
Background: Field 9, the “Pool Interest Rate”, on the Factor II files (factorA2_YYYYMM.zip and factorB2_YYYYMM.zip) currently provides the original interest rate and not the current-period interest rate for HMBS “RF” Pool Types.
A future enhancement to the G2 Factor files will correct the “Pool Interest Rate” (field 9) for HMBS “RF” Pool Types; until then, the “HSuppl_YYYYMM.txt” file will provide the interest rate as of the Report Period. Note that there is no change to the Factor files related to this bulletin and that this bulletin only relates to HMBS “RF” Pool Types.
