Based on the results of the procedures performed, there is a 95.0% confidence level that the maximum estimated error occurrence rate for each of the attributes across the entire population of 7,157 Student Loans in the Data File does not exceed 5.0%.

We were engaged by the Company to perform this agreed-upon procedures engagement. We conducted our engagement in accordance with attestation standards established by the American Institute of Certified Public Accountants, which involves us performing the specific procedures agreed to and acknowledged above and reporting on findings based on performing those procedures. We were not engaged to, and did not, conduct an examination or review, the objective of which would be the expression of an opinion or conclusion, respectively, on the specified attributes in the Data File. 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.

We are required to be independent of the Responsible Party and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements related to our agreed-upon procedures engagement.

The procedures performed were applied based on the information included in the Data File and Provided Information, without verification or evaluation of such information by us; therefore, we express no opinion or any other form of assurance regarding (i) the reasonableness of the information provided to us by the Responsible Party, (ii) the physical existence of the Student Loans, (iii) the reliability or accuracy of the Provided Information which was used in our procedures, or (iv) matters of legal interpretation.

The procedures performed were not intended to address, nor did they address: (i) the conformity of the origination of the Student Loans to stated underwriting or credit extension guidelines, standards, criteria or other requirements, (ii) the value of collateral securing any such Student Loans being securitized, (iii) the compliance of the originator of the Student Loans with federal, state, and local laws and regulations, or (iv) any other factor or characteristic of the Student Loans that would be material to the likelihood that the issuer of the asset-backed securities will pay interest and principal in accordance with applicable terms and conditions. The procedures performed were not intended to satisfy any criteria for due diligence published by the nationally recognized statistical rating organizations (“NRSROs”).

The terms of our engagement are such that we have no responsibility to update this report because of events and circumstances that may subsequently occur.

This report is intended solely for the information and use of the Specified Parties.

	d) Recompute the Current Principal Balance as follows:
	i. Add any applicable Repayment Fee (shown under the “RPMT FEE” field on #ED2 Screen) or applicable Capitalized Interest (shown under the “CAP INT” field on #ED2 Screen) to the “ACCOUNT BALANCE” column on #CSS Screen, and subtract any applicable disbursement amount (shown under the “DISBURSEMENT” field on #CSS Screen or the #CDS Screen), applicable adjustment (shown under the “ADJUSTMENT” field on #CSS Screen or the #CDS Screen), or applicable disbursement return amount (shown under the “MEMO TEXT” field on #CMS Screen);

	ii. Subtract any amount indicated in the “RETRO PROCESSING” field on #ED2 Screen and any additional principal payment applied after the Cutoff Date, identified by subtracting the recalculated accrued interest (“Interest Rate” field on #CSS Screen multiplied by the number of days from the start of the CYCLE DATE on #EDH Screen to the day before the date of the first Payment under the “PAYMENT” field on #CSS Screen or the #CDS Screen, multiplied by the “ACCOUNT BALANCE” column on #CSS Screen) from the first Payment made under the “PAYMENT” field on #CSS Screen or the #CDS Screen; and,
	iii. Subtract any principal paid amount in the “PRINCIPAL PAID” field from the Amortized Payment History Schedule after the last transaction date reflected in the #CSS Screen but before the Cutoff Date.
Remaining Term	Recompute as follows:
	(i) Subtract the Cutoff Date from either (1) the date one month after the “MATURITY DT” field on #EDH Screen, or (2) the date indicated in the notation of status change on #CIS Screen.
	(ii) Divide the result by the average number of days in a month (i.e., 30.4375, based on 365.25 days in a year).
	(iii) If the Cutoff Date was later than the “DUE DATE” field on #EDH Screen, subtract one month from (ii).
School Type	School Type is considered to be “No” (not undergraduate) if the school name in the “underwritten_education_ school_ name” field in the Data File indicates either (i) the underwritten school is a high school or (ii) “NULL” and the “is_parent_plus” field in the Data File indicates “Yes.”
School Name	School Name is considered to be
	• The school name with the most recent, highest completed degree, in the “Educations” section of the Verify Report Page.
	• The name of the borrower’s parent’s high school if (i) the school name in the “underwritten_education_school_name” field in the Data File is a high school and (ii) the “is_parent_plus” field in the Data File indicates “Yes.”
	• “No” if the “Educations” section of the Verify Report Page or the “Underwritten Education Degree” field in the Application Underwriting Snapshot Page indicates “incomplete_grads.”
School Name appearing in Title IV Federal Aid Programs	Instructions are listed in order of priority until the attribute was agreed:
	a) Compare the school name under the “underwritten_education_school_name” field in the Data File to the corresponding information on the Title IV Federal School Code List.
	b) Compare the U.S. Department of Education’s Office of Postsecondary

	Education (OPE) code under the “underwritten_ education_opeid” field in the Data File to the “SchoolCode” field in the Title IV Federal School Code List.
	c) Observe whether the school name under the “underwritten_education_ school_name” field in the Data File appeared in the “Institution_Name” field in the Accredited Programs List.
	d) Observe whether the school name under the “underwritten_education_ school_name” field in the Data File appears in the “Educations” section of the Verify Report Page or “Underwritten Education School Name” field in the Application Underwriting Snapshot Page for Selected Student Loans.
	In the event the school name in the “underwritten_education_school_name” field in the Data File indicates the underwritten school is a high school or “NULL,” observe if the “is_parent_plus” field in the Data File indicates “Yes,” which represents Parent Plus loan and therefore the parent’s highest achieved education was used to originate the loan. If the highest achieved education is high school or “NULL,” the parent did not possess a collegiate degree, and there would be no corresponding OPE code for the loan within the Title IV Federal School Code List or Accredited Programs List.
	In the event the school name in the “underwritten_education_school_name” field in the Data File indicates the school is a satellite campus, but the Title IV Federal School Code List or the Accredited Programs List designation is not available at the satellite campus level, compare the name of the college or university to which the satellite campus relates to the Title IV Federal School Code List or the Accredited Programs List.
School Degree	School Degree is considered to be:
	• The most recent, highest completed degree, in the “Educations” section of the Verify Report Page.
	• “Masters” or “MD” if the “Educations” section of the Verify Report Page or the “Underwritten Education Degree” field in the Application Underwriting Snapshot Page indicates “medical_other” or “DO,” respectively.
	• “NonGrad” if the “Educations” section of the Verify Report Page or the “Underwritten Education Degree” field in the Application Underwriting Snapshot Page indicates “incomplete_grads.”
	• “High School” if (i) the school name in the “underwritten_education_ degree” field in the Data File is a high school and (ii) the “is_parent_plus” field in the Data File indicates “Yes.”
