A credit score is a number that represents an estimate of an individual's financial creditworthiness as calculated by a statistical model. A credit score attempts to quantify the likelihood that a prospective borrower will fail to repay a loan or other credit obligation satisfactorily. A credit score is based on a subset of the information in an individual's credit report. Lenders such as banks and credit card companies use credit scores to manage the risk posed by lending money to consumers. Examples of such uses include determining who qualifies for a loan, assigning an interest rate, assigning credit limits, and managing accounts that are already open (for example, treatment of accounts that are in default). The use of credit or identity scoring prior to authorizing access or granting credit is an implementation of a trusted system.
