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:

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

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.

Procedures performed and our associated findings

1.
As instructed by the Sponsor, on behalf of the Depositor, we randomly selected a sample of 1,000 Receivables from the Receivable Listing 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 Receivable Listing File.

For the purpose of the procedures described in this report, the 1,000 Sample Receivables are referred to as Sample Receivable Numbers 1 through 1,000.

2.
For each device payment plan agreement on the Receivable Listing File and Data File, we compared the receivable number, as shown on the Receivable Listing File, to the corresponding receivable number, as shown on the Data File, and noted that:
a.
All of the Receivables (including the Sample Receivables) were included on both the Receivable Listing File and Data File and
b.
No device payment plan agreement other than the Receivables were included on the Receivable Listing File or Data File.

3.
For each Sample Receivable, we

a.
Compared the Sample Characteristics listed on Exhibit 1 to Attachment A, as shown on the Data File, to the corresponding information located on, or to the corresponding information we recalculated using information located on, the Sources, 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(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 payment frequency, as shown on the Data File, was “monthly.”

For the purpose of recalculating and comparing the number of device payments on account Sample Characteristic for Sample Receivable Number 124, the Sponsor, on behalf of the Depositor, instructed us to add the:

For the purpose of comparing the current loan balance Sample Characteristic for each Sample Receivable (except for Sample Receivable Numbers 448, 582, 584 and 788), the Sponsor, on behalf of the Depositor, instructed us to use the System Screen Shots as the Source or recalculate the current loan balance by subtracting the:
a.
TOT_APPLIED_PMT_AMT from
b.
INSTALL_LOAN_AMT,
both as shown on the Vision Files, (and in accordance with any other applicable note(s)).

For the purpose of recalculating and comparing the current loan balance Sample Characteristic for Sample Receivable Numbers 448, 582, 584 and 788, the Sponsor, on behalf of the Depositor, instructed us to subtract the sum of the corresponding RECEIVED_AMT, all as shown on the Current Loan Balance Schedule, from the original loan amount, as shown on the Vision Files.
