The procedures we were instructed by the Company to perform and the associated findings are as follows:
| A. | We randomly selected a sample of 150 Receivables from the Data File (the “Sample Receivables”) using a random sampling tool. For purposes of this procedure, the Company did not inform us of the basis they used to determine the number of Receivables we were instructed to randomly select from the Data File. |
| B. | For each Sample Receivable, we compared the specified attributes in the Data File listed below to or using the corresponding information included in the Receivable File, utilizing the Instructions, as applicable. The Company indicated that the absence of any of the information in the Receivable File or the inability to agree the indicated information from the Data File to the Receivable File for each of the attributes identified, utilizing the Instructions as applicable, constituted an exception. The Receivable File documents are listed in the order of priority, with the highest priority document listed first. |

| 1. | Title Document. We were instructed by the Company to observe that one of the Acceptable Company Names appeared on the Title Document as the Lien Holder, Owner, Security Interest Holder, or Secured Party. | |
| 2. | Proof of Insurance. The Company instructed us to consider an Insurance Document to be acceptable proof of insurance. The Company further instructed us that no Insurance Document was required for Sample Receivables with the characteristics listed below because its underwriting policy does not require proof of insurance for these receivable types: |

| (i) | Stip Tier 1 (Type “ST01” on the Analysis 1 screen in the Company’s servicing system) | |
| (ii) | Stip Tier 2 (Type “ST02” on the Analysis 1 screen in the Company’s servicing system) or Stip Tier 3 (Type “ST03” on the Analysis 1 screen in the Company’s servicing system) for which: |
| a. | the Loan Application Update screen in the Company's servicing system indicated that the signed contract was received prior to April 1, 2024, or | |
| b. | the Credit Report Inquiry screen in the Company’s servicing system indicated the customer had an open automobile or mortgage loan and the value in the “Program” column in the Data File was “PREF.” |
As such, the absence of an Insurance Document for Sample Receivables with these receivable types was not considered an exception.
| 3. | Signed Credit Application (not applicable to direct loans). We make no representation regarding the authenticity of the obligor’s signature(s). |
We found such information to be present.
