Non-Agency Securitization Techniques and Structures

While the issuance of mortgage-backed securities virtually stopped in the wake of the financial crisis, it has recently begun to grow rapidly due largely to the popularity of Non-Qualified (non-QM) loans. Since these loans are not eligible for securitization by Ginnie Mae, Fannie Mae, or Freddie Mac, they are issued as non-agency or “private-label” transactions. However, these transactions do not receive any form of government guarantee or credit enhancement, which means that the credit support for the senior bonds must be built into its structure. Understanding the workings of these structures is therefore critical to managing fixed-income portfolios and assets.The session will first help students understand how the market for non-agency MBS functions and how it and the agency market(s) are related. It will introduce students to the concept of “structured” MBS and why they are created for both agencies- and non-agency-eligible loans. The course will introduce credit-structure concepts including “subordination” and how the structure, as well as the pricing of its elements, dictates the economics of the transaction. Finally, the session will discuss how mortgage credit evolves over time and how structures are designed to account for this evolution.Areas Covered Agency and non-agency MBS productsAgency and non-agency MBS marketsStructured MBS basicsMBS structuring techniquesTime tranching vs credit tranchingSenior/subordinate structuresMortgage credit evolution and “adverse selection”Course Level - IntermediateWho Should AttendEmployees of mortgage lenders Bankers Bond InvestorsRegulatorsTopic BackgroundA description of the securitization mechanisms used to distribute mortgage loans that cannot be securitized through Agency channels.
