Training Objectives

The purpose of this training is to:

• Provide an overview of Ginnie Mae’s MISMO adoption effort

• Introduce the MISMO Compliant Pool Delivery Dataset (PDD)

• Demonstrate the Validation & Testing Tool (VTT)

• Guide Issuers and Vendors toward the available resources and support

Introduction to Ginnie Mae’s MISMO Adoption Effort

Pool Delivery Dataset (PDD)

MISMO v3.3-compliant XML-formatted data for Single Family pools

Single Family Pool Delivery Module (SFPDM)

New production application for PDD submissions to replace GinnieNET

</>Validation and Testing Tool (VTT)

New testing application for validating PDD structural and data qualifications

I M P L E M E N TAT I O N F E AT U R E S

Ginnie Mae seeks to adopt the Mortgage Industry Standards Maintenance Organization (MISMO) standard for its Single Family issuance pool delivery data.

• Similar to other MISMO compliant datasets, such as the Government Sponsored Enterprises’ (GSEs) Uniform Loan Delivery Dataset (ULDD)

• Created data requirements and technology for submission of the Pool Delivery Dataset (PDD)

Focus of today’s training presentation

4

• PDD data is formatted based on MISMO v3.3 XML schema definitions.

• PDD-specific XML schema definitions (XSDs) and documented XPATHs indicate where each data element should appear in the PDD structure.

The PDD is based on ULDD structure and data requirements, with some key similarities and differences:

Comparison of Data ElementsUnique to PDD

• User submits pool-level data, such as loan count and UPB aggregates (ULDD only contains loan-level data)

Similar with ULDD

• Similar hierarchical XML structure

• Concepts like XPATH, Conditionality, and Loan States apply in the same way

Although the PDD is new to deliver single family pool and loan data for Ginnie Mae securitization, it will be familiar to those that have worked with MISMO standards and deliver the ULDD to the GSEs

Validation & Testing Tool (VTT) Overview

The PDD Validation and Testing Tool is available within the MyGinnieMae portal and is intended for Issuers to test and validate their PDD submission files prior to processing by the SFPDM.

Validations on structure and content are performed via a two-step process:1. Structural validations verify XML file structure and data formats2. Business Rule validations validate the file’s adherence to Ginnie Mae’s

Business Rules.

Users with the following functional roles will automatically have VTT access:

• SF-Loan Delivery and Pooling Basic User

• SF-Loan Delivery and Pooling Authorized Signer

Other users can request the SF-VTT Access from their Organization AdminsVendors should reach out to GinnieMae_MISMO_Support@hud.gov for instructions to access the VTT.

Purpose

Process

Access

Ginnie Mae has released the VTT to all Single Family Issuers for immediate use. LOS Vendors also have access to VTT upon request.*

*If you use an LOS Vendor to deliver pools to Ginnie Mae and have not provided Ginnie Mae with which Vendor / product your organization uses, please send an email to GinnieMae_MISMO_Support@hud.gov with that information.

PDD SUPPORT

PDD VALIDATION

Ginnie Mae encourages Issuers to recreate the XML Samples in PDD Implementation Guide Appendices B and C.

Please Note: These samples have been updated in the January 2021 release.

Ginnie Mae is available to support Issuers and Vendors throughout the PDD development and testing process.

Issuers and Vendors have access to validate their PDD test files through VTT. Ginnie Mae will work with Issuers/Vendors to understand adoption progress and best practices of PDD development and testing.
