All Participant Memorandum (APM)
APM 14-09: Ginnie Mae MISMO Adoption Update
Published Date: 6/30/2014 1:00 AM

Today, Ginnie Mae has published the complete set of Pool Delivery Dataset (PDD) technical implementation resources which includes the PDD Implementation Guide and all appendices. These resources replace and expand upon the previous version of the PDD Implementation Guide released on the Ginnie Mae website on March 31, 2014. The PDD is a component of Ginnie Mae’s commitment to align with the mortgage industry and adopt the MISMO standard for the transfer of pool delivery data. The PDD technical implementation resources are designed to facilitate Issuers’ transition from current flat files to future PDD XML files.

The PDD XML files will replace the existing electronic flat files for the data required on Forms HUD-11705 (Schedule of Subscribers and Ginnie Mae Guaranty Agreement) and HUD-11706 (Schedule of Pooled Mortgages) for single-family pool delivery.

In order to successfully implement the PDD, Issuers should:
  • Review the PDD technical implementation resources
  • Analyze their current systems and processes to determine the modifications necessary to generate the PDD XML files
  • Participate in Ginnie Mae training on the PDD XML submission process
  • Participate in Ginnie Mae integration testing and validation of PDD XML files

What is the Pool Delivery Dataset? Ginnie Mae has contributed to and leveraged the MISMO Residential Specifications Version 3.3 Reference Model to create the PDD. The PDD is a subset of the MISMO reference model data points and provides a comprehensive list of pool and loan level data points that will be required for electronic delivery of new single-family pool issuances. The PDD contains some unique data points that may not be included in other MISMO compliant datasets in the mortgage industry.

What does the MISMO Adoption Project encompass? The MISMO adoption effort will drive the modernization of Ginnie Mae’s systems and processes. This modernization effort includes the transition from flat files to PDD XML files as well as the development of the new Single Family Pool Delivery Module (SFPDM). Ginnie Mae’s SFPDM is the new application that will receive and validate the PDD XML files during the submission process. Ginnie Mae’s implementation plan provides for training, testing and adoption support for Issuers prior to delivery of PDD XML files.

Technical Implementation Resources

The PDD Implementation Guide is provided to assist Ginnie Mae Issuers in adopting the MISMO standards for delivery of single-family pool and loan data in the PDD XML format. Detailed technical specifications and usage scenarios are included in its Appendices. Ginnie Mae is also providing Quick Guides and Frequently Asked Questions (FAQs) to provide additional information. All resources are available on www.ginniemae.gov.
