Section 1254.7 - Credit Score Assessment(a)Requirement for Credit Score Assessment. An Enterprise will undertake a Credit Score Assessment of each application that the Enterprise determines to be complete. An Enterprise must determine whether an application passes the Credit Score Assessment.(b)Testing for Credit Score Assessment. An Enterprise must conduct statistical tests for accuracy and reliability that use one or more industry standard statistical tests for demonstrating divergence among borrowers' propensity to repay using the industry standard definition of default, applied to mortgages purchased by an Enterprise (including subgroups), as identified by the Enterprise.(c)Criteria for Credit Score Assessment. The Credit Score Assessment is based on the following criteria:(1)Testing for accuracy. A credit score model is accurate if it produces a credit score that appropriately reflects a borrower's propensity to repay a mortgage loan in accordance with its terms, permitting a credit score user to rank order the risk that the borrower will not repay the obligation in accordance with its terms relative to other borrowers.(i)Initial Credit Score Assessment. For the Credit Score Assessment of applications submitted in response to the initial solicitation under § 1254.5(e) , a credit score model meets the test for accuracy if it produces credit scores that meet a benchmark established by the Enterprise in the initial Credit Score Solicitation, as demonstrated by appropriate testing.(ii)Subsequent Credit Score Assessments. For the Credit Score Assessment of applications submitted in response to any later solicitation under this part, a credit score model meets the test for accuracy if it produces credit scores that are more accurate than the credit scores produced by any credit score model that is required by the Enterprise at the time the test is conducted, as demonstrated by appropriate testing.(2)Testing for reliability. A credit score model is reliable if it produces credit scores that maintain accuracy through the economic cycle. The Credit Score Assessment must evaluate whether a new credit score model produces credit scores that are at least as reliable as the credit scores produced by any credit score model that is required by the Enterprise at the time the test is conducted, as demonstrated by appropriate testing. Testing for reliability must demonstrate accuracy at a minimum of two points in the economic cycle when applied to mortgages purchased by an Enterprise (including subgroups), as identified by the Enterprise.(3)Testing for integrity. A credit score model has integrity if, when producing a credit score, it uses relevant data that reasonably encompasses the borrower's credit history and financial performance. The Credit Score Assessment must evaluate whether a credit score model applicant has demonstrated that the model has integrity, based on appropriate testing or requirements identified by the Enterprise (which may address, for example, the level of aggregation of data or whether observable data has been omitted or discounted when producing a credit score).(4)Other requirements. An Enterprise may establish requirements for the Credit Score Assessment in addition to the criteria established by FHFA.(c)Third-party testing. Testing required for the Credit Score Assessment may be conducted by:(2) An independent third party selected or approved by an Enterprise.(d)Timing of Credit Score Assessment.(1) An Enterprise must notify the applicant when the Enterprise begins the Credit Score Assessment. The Credit Score Assessment will begin no earlier than the close of the solicitation time period, unless FHFA has determined that an Enterprise should begin a Credit Score Assessment sooner. The Credit Score Assessment will extend for 180 days. FHFA may authorize not more than two extensions of time for the Credit Score Assessment, which shall not exceed 30 days each, upon a written request and showing of good cause by the Enterprise.(2) An Enterprise must provide notice to the applicant within 30 days of a determination that the application has passed the Credit Score Assessment.
