Securitization is a process where long-term financial assets like loans are pooled together and converted into marketable securities that can be sold to investors. This provides the originator with cash while transferring the credit risk to the investors. The document discusses the parties and stages involved including identification of assets, transfer to a special purpose vehicle, issuing securities to investors, and redemption upon repayment or default of underlying assets. Guidelines are provided on selecting high quality assets and ensuring proper structures, risk ratings, and regulations are in place for a successful securitization program.
