BA13, my understanding is that you would report your final. You only report multiple (iv) if your situation doesn't meet any of the waterfall scenarios.
If a financial institution obtains two or more AUS results and the AUS generating one of those results corresponds to the loan type reported pursuant to § 1003.4(a)(2), the financial institution complies with § 1003.4(a)(35) by reporting that AUS name and result. For example, if a financial institution evaluates an application using the Federal Housing Administration's (FHA) Technology Open to Approved Lenders (TOTAL) Scorecard and subsequently evaluates the application with an AUS used to determine eligibility for a non-FHA loan, but ultimately originates an FHA loan, the financial institution complies with § 1003.4(a)(35) by reporting TOTAL Scorecard and the result generated by that system. If a financial institution obtains two or more AUS results and more than one of those AUS results is generated by a system that corresponds to the loan type reported pursuant to § 1003.4(a)(2), the financial institution identifies which AUS result should be reported by following the principle set forth below in comment 4(a)(35)-3.ii.
ii. If a financial institution obtains two or more AUS results and the AUS generating one of those results corresponds to the purchaser, insurer, or guarantor, if any, the financial institution complies with § 1003.4(a)(35) by reporting that AUS name and result. For example, if a financial institution evaluates an application with the AUS of Securitizer A and subsequently evaluates the application with the AUS of Securitizer B, but the financial institution ultimately originates a covered loan that it sells within the same calendar year to Securitizer A, the financial institution complies with § 1003.4(a)(35) by reporting the name of Securitizer A's AUS and the result generated by that system. If a financial institution obtains two or more AUS results and more than one of those AUS results is generated by a system that corresponds to the purchaser, insurer, or guarantor, if any, the financial institution identifies which AUS result should be reported by following the principle set forth below in comment 4(a)(35)-3.iii.
iii. If a financial institution obtains two or more AUS results and none of the systems generating those results correspond to the purchaser, insurer, or guarantor, if any, or the financial institution is following this principle because more than one AUS result is generated by a system that corresponds to either the loan type or the purchaser, insurer, or guarantor, the financial institution complies with § 1003.4(a)(35) by reporting the AUS result generated closest in time to the credit decision and the name of the AUS that generated that result. For example, if a financial institution evaluates an application with the AUS of Securitizer A, subsequently again evaluates the application with Securitizer A's AUS, the financial institution complies with § 1003.4(a)(35) by reporting the name of Securitizer A's AUS and the second AUS result. Similarly, if a financial institution obtains a result from an AUS that requires the financial institution to underwrite the loan manually, but the financial institution subsequently processes the application through a different AUS that also generates a result, the financial institution complies with § 1003.4(a)(35) by reporting the name of the second AUS that it used to evaluate the application and the AUS result generated by that system.
iv. If a financial institution obtains two or more AUS results at the same time and the principles in comment 4(a)(35)-3.i through .iii do not apply, the financial institution complies with § 1003.4(a)(35) by reporting the name of all of the AUSs used by the financial institution to evaluate the application and the results generated by each of those systems. For example, if a financial institution simultaneously evaluates an application with the AUS of Securitizer A and the AUS of Securitizer B, the financial institution complies with § 1003.4(a)(35) by reporting the name of both Securitizer A's AUS and Securitizer B's AUS and the results generated by each of those systems. In any event, however, the financial institution does not report more than five AUSs and five results. If more than five AUSs and five results meet the criteria in this principle, the financial institution complies with § 1003.4(a)(35) by choosing any five among them to report.
