Adding MIP Data to MBS Daily Loan Level New Issuance File
Published Date: 11/16/2015

Ginnie Mae is enhancing the disclosure of Ginnie II program information by providing Multiple Issuer Pools (MIP) in the MBS Daily (Loan Level) file, File Name: “”. MIP data will be added to this file, beginning with December 2015 New Issuances. No changes to the MBS Loan Level Daily layout are required. The scheduled publish time of 9 AM for this file will remain the same.

A Ginnie Mae II MIP is a single pool in which one or more Issuers participate and submit loans throughout the month. The combined loan packages are used to back a single issuance of securities. The MIP loan packages are aggregated by coupon rate and term, and the Multiple Issuer Pool is finalized.

MIP Finalization: A Multiple Issuer Pool can potentially increase in size over the course of the month, until MIP finalization. The disclosure file published four business days prior to the end of the month (and thereafter) will reflect finalized MIP pools (the “” files published on December 28th, 2015 - January 4th, 2016 are examples of files containing finalized MIPs).
