has changed in 1970 where new innovative concept of tranching was introduced in issuing the securities (tranched securities). These tranched securities are sold to investors. Kaptan and Telang (2002)

(Uzun and Web, 2007) makes understanding of asset securitization more simple through an illustration of the process of asset securitization, banks which are financial intermediaries in capital market has various types of assets such as mortgage loans, car loans, leasing contracts etc on their balance sheets. These assets are not marketable so these are illiquid assets. Banks, to get rid of these illiquid assets and to attain financial freedom in lending search for new techniques. This innovative method of converting these illiquid assets in to liquid assets technique is called asset securitization. So asset securitization plays a major role in converting these illiquid assets in to cash flows (liquid assets).

Uzun and Web, also provide information on what kind of assets the banks securitize. These authors explain this as, the process of asset securitization starts with banks deciding which assets they want to securitize for example mortgage loans.

Investors invest on these securities and investment risk is directly interrelated to credit quality of loan borrowers whose loans are offered as collateral for the securities. To boost the demand for these securities the SPV enhances credit quality by process called over collateralization and subordination.

Over collateralization, is the process in which credit quality is improved by giving payment guarantee by insurer. So if there is any principal or interest default it is insured there by making investors clear in mind that there is no risk involved in investing in these securities. Over collateralization is one way of credit enhancement but the principle way of credit enhancement is done by subordination.
