The United States Federal Deposit Insurance Corp. defines the term Sub-Prime as the credit characteristics of the personal borrowers. Subprime borrowers were the delinquent borrowers who caused charge-offs, judgments and bankruptcies, all because of their payment delinquencies.
In addition to that, it had also been noticed that the majority of the borrowers who had taken loans against property mortgages did not have the repayment capacity. In fact, subprime borrowers are these types of borrowers. These loans, hence, had a higher risk of default.
