Dear Sirs/Madams,

 
PROPOSED ISSUE BY NEWDAY FUNDING MASTER ISSUER PLC OF SERIES 2025-2 OF CREDIT CARD RECEIVABLES-BACKED FLOATING AND/OR FIXED RATE SECURITIES (the “Issue”)
 
We have performed the procedures enumerated below on certain credit card receivables (the “Loan Pool”), which were agreed to by the Issuer, the Transferor, the Co-Arranger, the Arrangers, the Joint Lead Managers, the Dealers and the other Dealers (as defined in the Engagement Letter). The procedures were performed to assist you in evaluating the validity of certain characteristics of the Loan Pool. This agreed upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. The appropriateness of these procedures is solely the responsibility of the Issuer, the Transferor, the Co-Arranger, the Arrangers, the Joint Lead Managers and the Dealers. Consequently, we make no representation regarding the appropriateness of the procedures described below either for the purpose for which this report has been requested or for any other purpose.

This report (the “Asset Agreed Upon Procedures Report”) is addressed to the Board of Directors of the Issuer, the Board of Directors of the Transferor, the Co-Arranger, the Arrangers, the Joint Lead Managers and the Dealers identified in the Engagement Letter who have agreed to participate in the proposed Issue.

These procedures were established with the Issuer and the Transferor, and the appropriateness of the procedures is solely the responsibility of the Issuer, the Transferor, the Co-Arranger, the Arrangers, the Joint Lead Managers and the Dealers as discussed above. The Issuer and the Transferor shall be solely responsible for providing accurate and complete information requested by Deloitte necessary to perform the procedures. Deloitte has no responsibility for the accuracy or completeness of the information provided by or on behalf of the Issuer and the Transferor, even if Deloitte had reason to know or should have known of such inaccuracy or incompleteness.

The procedures that we performed and our findings are as follows:

1.
Scope of our work and factual findings

The procedures performed were as defined in Appendix 3 of the Engagement Letter (the “Agreed Upon Procedures”).

The Transferor provided us with a data file ‘OB_FINAL_OUTPUT_AUP_List_31Mar2025.csv’ (the “First Pool Run”) containing an account number for each of the 1,602,261 credit card receivables in the Loan Pool.

2



A random sample of 459 loans was selected from the First Pool Run using the sampling approach below (the “Sample”).

The Transferor then provided us with the data file ‘DT_ob_2025_sample_479.xlsx’ containing information for each loan in the Sample (the “Sample Pool”) as at 31 March 2025 (the “Cut-off Date”).

We have carried out the Agreed Upon Procedures on the Sample Pool during the period 14 to 24 April 2025.

The sampling approach

Sampling confidence is the probability that the actual errors, within a total population, are contained within the range of an estimate. Precision is the range of that estimate. The precision limit is the estimated maximum predicted number of errors within the total population. Sampling confidence and precision are stated in percentages.

Attribute sampling is a method of assessing the rate of occurrences of a specified attribute in a population and requires agreed upon procedures in relation to certain characteristics of a random sample of individual loans. In this case the Agreed Upon Procedures related to the documentation and procedures that support the Sample Pool contained in the First Pool Run.

Our method of calculating attribute sample sizes is based on the binomial probability distribution.
Statistical tests can only provide estimates of the error.

The procedures we have undertaken, set out in paragraphs 2.1 to 2.11 under the pool agreed upon procedures section below, have been limited to confirming that the selected attribute from the First Pool Run information relating to the Sample Pool agreed to the original loan documentation or copies thereof provided to us in the loan file. We are entitled to assume that the loan documentation is correct and we have not sought to independently verify this information. The loan documentation used in these Agreed upon Procedures was the Credit Agreement, Experian screenshot, NewServe and Vision, the primary systems of record (together, the “System”).

Objectives

On the assumption that the information in the First Pool Run is a complete and accurate representation of the Loan Pool, the sample sizes chosen were designed with the objective of us being able to state that there is a 99% confidence that not more than 1% of the population of the First Pool Run contained an error in the relevant attribute. Where errors were found in the Sample Pool, we have re-calculated the percentage errors that there might be in the First Pool Run and noted the revised percentage below. It is for you to ensure you understand this basis of reporting and to determine whether the errors are acceptable to you and for the purposes of the Issue.

2.
Pool agreed upon procedures

For each loan in the Sample Pool, we carried out the following agreed upon procedures and have given a confidence and precision percentage for each procedure.

For the purposes of this report, the failure of a single attribute is termed an error. We report our findings, which are the factual results of the agreed upon procedures performed:

2.1
Primary Cardholder’s Name
 
2.1.1
For each loan in the Sample Pool, we confirmed whether the primary cardholder’s full name shown in the Sample Pool substantially agreed to the primary cardholder’s full name on the Credit Agreement or the Experian screenshot.

We found that the primary cardholder’s full name substantially agreed to the Credit Agreement or the Experian screenshot, with no exception.
 
As a result of the procedure performed there is a 99% confidence that not more than 1% of the First Pool Run contained errors.
