We have performed the procedures enumerated in Attachment A, which were agreed to and acknowledged as appropriate by the Depositor, Sponsor, USAA, SMBC Nikko Securities America, Inc., J.P. Morgan Securities LLC, TD Securities (USA) LLC and U.S. Bancorp Investments, Inc.

This report may not be suitable for any other purpose. The procedures performed may not address all of the items of interest to a user of the report and may not meet the needs of all users of the report and, as such, users are responsible for determining whether the procedures performed are appropriate for their purposes. The appropriateness of these procedures is solely the responsibility of the Specified Parties identified in this report. No other party acknowledged the appropriateness of the procedures. Consequently, we make no representation regarding the appropriateness of the procedures described in Attachment A, either for the purpose for which this report has been requested or for any other purpose.

The procedures performed and our associated findings are included in Attachment A.

The procedures included in Attachment A were limited to comparing, recalculating or observing, as applicable, certain information that is further described in Attachment A. The Depositor is responsible for the Subject Matter, Preliminary Data File, Source Documents, Sample Characteristics and the determination of the instructions, assumptions and methodologies that are described herein. We were not requested to perform, and we have not performed, any procedures other than those listed in Attachment A. We have not verified, and we make no representation as to, the accuracy, completeness or reasonableness of the Source Documents or any other information provided to us, or that we were instructed to obtain, as applicable, by the Sponsor, on behalf of the Depositor, upon which we relied in forming our findings. Accordingly, we make no representation and express no opinion or conclusion as to (a) the existence of the Preliminary Receivables or Receivables, (b) questions of legal or tax interpretation or (c) the appropriateness, accuracy, completeness or reasonableness of any instructions, assumptions or methodologies provided to us by the Sponsor, on behalf of the Depositor, that are described in this report.

This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants (the “AICPA”). An agreed-upon procedures engagement involves the practitioner performing specific procedures that the Specified Parties have agreed to and acknowledged to be appropriate for the purpose of the engagement and reporting on findings based on the procedures performed. We were not engaged to, and did not, conduct an examination to express an opinion or a review to express a conclusion in accordance with attestation standards established by the AICPA on any of the items referred to herein. Accordingly, we do not express such an opinion or conclusion. Had we performed additional procedures, other matters might have come to our attention that would have been reported to you.

The agreed-upon procedures described in this report were not performed for the purpose of:

 

a.	Satisfying any criteria for due diligence published by a nationally recognized statistical rating organization (a “rating agency”) or

 

b.	Making any findings with respect to:

 

i.

Whether the origination of the Receivables conformed to, or deviated from, stated underwriting or credit extension guidelines, standards, criteria or other requirements,

 

ii.

The value of the collateral securing the Receivables,

 

iii.

Whether the originator(s) of the Receivables complied with federal, state or local laws or regulations or

 

iv.

Any other factor or characteristic of the Receivables that would be material to the likelihood that the issuer of the Notes will pay interest and principal in accordance with applicable terms and conditions.

We are required to be independent of the Depositor and to meet our other ethical responsibilities, as applicable, for agreed-upon procedures engagements set forth in the Preface: Applicable to All Members and Part 1 – Members in Public Practice of the Code of Professional Conduct established by the AICPA. Independence requirements for agreed-upon procedures engagements are less restrictive than independence requirements for audit and other attestation services.

This report is intended solely for the information and use of the Specified Parties and is not intended to be, and should not be, used by anyone other than the Specified Parties. It is not intended to be, and should not be, used by any other person or entity, including investors and rating agencies, who are not identified in the report as Specified Parties but who may have access to this report as required by law or regulation.

Procedures performed and our associated findings

 

1.

As instructed by the Sponsor, on behalf of the Depositor, we randomly selected a sample of 100 Preliminary Receivables from the Preliminary Data File (the “Sample Receivables”). For the purpose of this procedure, the Sponsor, on behalf of the Depositor, did not inform us as to the basis for how they determined the number of Sample Receivables or the methodology they instructed us to use to select the Sample Receivables from the Preliminary Data File.

For the purpose of the procedures described in this report, the 100 Sample Receivables are referred to as Sample Receivable Numbers 1 through 100.

 

2.	For each Sample Receivable, as applicable, we:

 

a.

Compared the Sample Characteristics listed on Exhibit 1 to Attachment A, as shown on the Preliminary Data File, to the corresponding information located in, or to the corresponding information we recalculated using information located in, the Source Documents, subject to the instructions, assumptions and methodologies provided by the Sponsor, on behalf of the Depositor, described in the notes to Exhibit 1 to Attachment A. The Source Document(s) that we were instructed by the Sponsor, on behalf of the Depositor, to use for each Sample Characteristic are shown on Exhibit 1 to Attachment A. All such compared information was found to be in agreement.

 

b.

Observed that the Contract contained a signature or typed electronic signature in the borrower signature section of such Contract. We performed no procedures to determine the validity of the signature or typed electronic signature contained in the borrower signature section of the Contract.

 

c.

Observed that the Contract contained truth-in-lending disclosure information.

 

d.

Observed that the System Screen Shots contained a lien status code of “3,” which the Sponsor, on behalf of the Depositor, indicated is evidence:

 

(i)

Of a lien status of “lien perfected” and

 

(ii)

That the Sponsor or USAA was the lien holder.

We performed no procedures to determine the validity of the lien status code in the System Screen Shots.

 

e.

Observed:

 

(i)

The existence of a Subvention Program Document if the PCD_SUBVENTION1 (“subvention”) was “CBSS” or ”NCPO,” as shown on the Preliminary Data File, or

 

(ii)

That the System Screen Shots contained an Auto DR of “Y” if the subvention was “ACH,” as shown on the Preliminary Data File.
