Tanım:
Securitization is the process of selling non-conventional loan packages to investors (public or private) who represent an interest in the cash flow generated by asset-backed loans. Loans are sold to a trustee (for cash), who in turn sells the loan (in bond form) to investors.

The process of pooling certain assets, of a company or a financial institution, which have regular repayment schedules, eg, housing mortgages, credit card loans, etc., and using them as collateral for the issue of the asset-backed securities to be distributed to investors

Securitization is the process of pooling various types of debt-mortgages, car loans, or credit card debt-and packaging them as bonds, which are then sold to investors. These bonds may also be known as asset-backed securities because the interest and return of principal they promise are based on the value of the underlying assets. Those assets could be the property, such as cars or homes purchased with the original loans, or accounts receivable, which are monies owed to the lender.
