<!--The following narrative describes the information containted in the data fields filed on Schedule AL of Form ABS-EE.  The number refers to the field name and the description refers to the description of the field set forth in Item 1125 of Regulation AB. If a field does not include an explanatory narrative, the depositor has determined that the description of the field in Item 1125 of Regulation AB is self-explantory. In some cases, the depositor omitted a field because the requirement is inapplicable to the receivables or to the transaction.  In those cases, the depositor has described the reason why that field is inapplicable. If a receivable has been repurchased by the depositor or the servicer in the prior reporting period, all of the fields related to the repurchased receivable will be omitted. To the extent that the sum of the data contained in a field for each receivable will equal an item included in the servicer's monthly report to securityholders (the "Servicer Report") filed on Form 10-D, the depositor will identify those fields in the related description.
Field - Description
6 - Origination Date (Item 3(c)(2))
The date specified in this field is the date the contract was signed by the related obligor.
7 - Original Loan Amount (Item 3(c)(3))
The amount specified in this field means, with respect to a receivable, the aggregate amount advanced toward the purchase price of the financed vehicle, including accessories, insurance premiums, service and warranty contracts andother items customarily financed as part of retail automobile instalement sale contracts and repurchase money loans and related costs.
8 - Orginal Loan Term (Item 3(c)(4))
The number specified in this field represents the number of months from and including the origination date to and including the original maturity date for the related receivable.  If the origination date occurs in, or any payment is due in, a specified month, that month will be included in this calculation.  For example, if the receivable was originated on January 31, the first payment is due on March 1 and the loan matures on September 1, the original loan term will be reported as 9 months.  The methodology used to populate this field differs from the original term as disclosed in the prospectus, which treats the term as the number of contractually required monthly payments to be received from the related obligor.
9 - Loan Maturity Date (Item 3(c)(5))
The date specified in this field represents the current expected final maturity date of the related receivable, including any permitted extensions.  If this field is omitted, the related receivable was charged-off or paid in full during the reporting period.
10 - Original interest rate (Item 3(c)(6))
The interest rate specified in this field is the interest rate that was effective at the time of origination for the related receivable and reflects any corrections to the original interest rate as reflected in a customer correction letter.
15 - Underwriting indicator (Item 3(c)(11))
The underwriting indicator field will be marked "true" if there are no exceptions to the underwriting criteria described below. If the related receivable at origination was originated with an exception to the underwriting criteria of Ally Bank as described below, the underwriting indicator field will be marked "false".
Ally Bank acquires or originates the receivables in the ordinary course of business from participating automobile and light truck dealers in accordance with the requirements of its agreements with dealers.
Ally Bank's process of acquiring receivables begins, in general, with the application by a customer for financing of a motor vehicle at the point of purchase from a participating dealer. Applications are initiated through websites established and maintained by the sponsor or its affilates or third parties.  Prior to December 31,2014, applications could also have been initiated by fax.
Ally Bank and Ally Financial currently use an underwriting process in which applications are reviewed solely by Ally Financial credit underwriters.  These credit underwriters use Ally Bank's underwriting standards when evaluating applications on behalf of Ally Bank. For receivables originated prior to May 2011, all applications were initially reviewed by Ally Financial, and then applications intended for Ally Bank were reviewed separately by Ally Bank. As the underwriting is done on behalf of Ally Bank and as Ally Bank retains the right to review all contracts and require Ally Financial to purchase any that fail to meet Ally Bank's standards, we generally refer to Ally Bank rather than Ally Financial when describing the underwriting process.
The application evaluation process begins wiht the placement of each application intio on of 14 analytical categories or "segments," based on specified aspects of the applicant's credit profile and, in many cases, whether the related vehicle is new or used. Ally Bank then evaluates each application by applying a proprietary credit scoring algorithm, which it refers to as a "scorecard," tailored to the applicable segment. Ally Financial designed the scorecards with assistance from a third party credit scoring company. Inputs used by the scorecards vary, but typically include, among other items: (1) severity and aging of delinquency; (2) number of credit inquiries; (3) loan-to-value ratio; and (4) payment-to-income ratio.  The scorecards are reviewed and updated on a periodic basis in order to account for changes in the perceived impact of specific inputs on applicant creditworthiness. The most recent scorecard redevelopment was implemented in January 2015.
The output of the proprietary scorecard is referred to as the "Ally score." The Ally score predicts the statistical likelihood that a loss will occur with respect to that receivable, but does not predict the performance of any receivable with certainty. Ally Bank uses the Ally score and other credit scores to sort applicants into 28 tier grades. Concurrently with this process, Ally Bank takes other steps to gather information regarding the applicant, such as checking lists maintained by the Office of Foreign Assets Control and performing fraud and duplicate application checks.
Once the information is gathered, Ally Bank analyzes the application to determine whether to approve it and other to repurchase the receivable. These determinations are made judgmentally on the basis of all the information available to Ally Bank, including the following:
the applicant's credit tier and Ally score,
the prospective purchaser's experience in managing instalment and revolving debt,
the asset value of the vehicle and the loan-to-value ratio for the receivable,
the term of the receivable, and
the prospective purchaser's ability to pay.
Ally Bank's standards also require physical damage insurance to be in place on each financed vehicle at the time of origination.
Applications are first evaluated through an automated process. Applications are approved or declined and credit decisions are made either entirely through the automated process or through the automated process followed by a manual review by a credit underwriter. Ally Bank developed its automated process in order to expedite the review of applications. The automated process uses an algorithm to approve applications with various combinations of credit factors that Ally Bank has observed over time will receive credit underwriter approval. As a result, there are many clusters of credit factors that will lead to an automated approval, rather than one or a few sets of benchmark characteristics. Final approval based solelyon automated approval, without manual review, is limited to the higher quality credit tiers. However, even in the highest quality credit tier, a significant portion of approved applications are approved by credit underwriters rather than by the automated process.
For approved applications, buy rates applicable to the instalment sale contracts are assigned on the basis of the Ally score in accordance with pricing tiers that are managed by Ally Financial and Ally Bank.
The sponsor may use programs developed and maintained by the sponsor or third parties that would allow it to complete the entire contracting process electronically. The resulting contracts will be electronically signed by the related obligors and maintained by the sponsor or third parties in electronic form only.
Ally Bank has established a series of policies, or "underwriting criteria," that apply to the review of a credit application. The underwriting criteria contain guidelines for many attributes of an application, such as a maximum loan-to-value ratio, maximum payment-to-income ratio and minimum credit score and, for lower credit quality applicants, maximum debt-to-income ratio. For used vehicles, additional guidelines exist for vehicle model year and mileage. Some, but not all, of these guidelines will vary according to the credit tier of the applicant or the term of the proposed contract, with a higher credit tier or a shorter contract term generally having a more permissive guideline.
Credit underwriters have a limited ability to approve exceptions to the guidelines contained in the underwriting criteria. Exceptions to the credit policies must be approved by credit underwriters with appropriate credit authority. Approved applicants that do not comply with all credit guidelines typically have strong compensating factors that indicat a high ability of the application to repay the receivable, such as a co-obligor, a lower loan-to-value ratio or a shorter loan term. Examples of underwriting exceptions may include allowing a longer term or a greater ratio of payment to income, debt to income or loan to value than the standard allowances for such criteria or allowing higher mileage or an earlier model year for a used vehicle. Ally Bank monitors exceptions to the guidelines, with the goals of limiting exceptions to a small portion of approved applications and rarely permitting more than a single exception for any contract.
16 - Grace period (Item 3(c)(12))
The number specified in this field represents the number of months from and including the origination date to but excluding the first payment date.  For example, if the origination date is January 31 and the first payment date is March 1, the grace period will be 2 months.
18 - Subvented (Item 3(c)(14))
If the value in the subvented field is equal to "1," the related receivable is a "subvented receivable." Some receivables are orginated under incentive programs sponsored by vehicle manufacturers, for which the financing rates are below the standard rates at which Ally Bank otherwise offers financing under retail contracts. Those receivables are referred to as subvented receivables.
Because the rates on the subvented receivables are lower than would otherwise be offered by Ally Bank, Ally Bank purchases those subvented receivables from the dealers and the applicable manufacturer pays the present value of the difference between the customer's subvented rate and Ally Bank's standard rate to Ally Financial on behalf of the dealer selling the related vehicle and Ally Finanical forwards such amount to Ally Bank.
Subvention is not taken into account by Ally Bank when determining the credit scoring.
The prospectus does not report cash subvention as a subvented receivable; however, [this filed will show cash subvention, indicated as a "2," if the obligor received cash in connection with the purchase of the related vehicle.
19 - Vehicle Manufacturer (Item 3(d)(1))
The vehicle manufacturer is the brand name of the related manufacturer and not the corporate parent of the manufacturer.  For example, Chevrolet or Cadillac will be included instead of General Motors.
21 - New or used (Item 3(d)(3))
For purposes of the new or used field, a demonstration or a loaner vehicle will be classified as a new vehicle.  Generally, the first time a dealer sells a vehicle to a consumer, the vehicle will be treated as a new vehicle.
23 - Vehicle type (Item 3(d)(5))
The methodology used to populate the vehicle type field conforms with the methodology used in creating the tables set forth in "The Receivables Pool" in the prospectus; however, for purposes of the prospectus disclosure, sport utility vehicles will be classified as trucks.
24 - Vehicle value (Item 3(d)(6))
The vehicle value field is populated based on the information contained in field number 25 below.
25 - Source of vehicle value (Item 3(d)(7))
If the source of vehicle value field is "invoice price," the vehicle value identified in field 24 above will be the sum of the manufacturer invoice price and the invoice price for any dealer installed accessories. With respect to used vehicles, the vehicle value is generally either based on the NADA guide, which will be marked "other," or the Kelley Blue Book.
26 - Obligor credit score type (Item 3(e)(1))
The data in the obligor credit score type field will be "Not Available" or "None" if the related obligor is a business without an individual co-obligor and there is no commercial bureau score available.  In the case of a business obligor without a co-obligor, a commercial bureau score will be included in this field if it is available.  If the related obligor is a business with a co-obligor that has a consumer bureau score, that co-obligor's consumer bureau score will be reported.  The obligor credit score type will differ from the prospectus because the prospectus classifies the obligor on the receivable as a business even if there is an individual co-obligor with a consumer bureau score.
27 - Obligor credit score (Item 3(e)(2))
If there is more than one obligor on the receivable, only the primary obligor's credit score will be reported in the obligor credit score field, unless the primary obligor is a business obligor with an individual co-obligor, in which case the individual co-obligor's score will be reported.  The credit score reported in this field will otherwise be the credit score described in field 26 above.
28 - Obligor income verification level (Item 3(e)(3))
In some cases, income will be "not stated, not verified," which is generally as a result of the credit application not including the relevant information when it was submitted.  With respect to a receivable with a business obligor that also has an individual co-obligor, the verification level attributable to the individual co-obligor is reported for this field.  If a receivable with a business obligor does not also have an individual co-obligor, the financial information of the related business may be reviewed and will be reported in this field.
29 - Obligor employment verification (Item 3(e)(4))
In some cases, employment will be "not stated, not verified," which is generally as a result of the credit application not including the relevant information when it was submitted.  In the case of a business obligor without an individual co-obligor, a "1" will generally be reported in this field because no employment verification has been completed.
31 - Payment-to-income ratio (Item 3(e)(6))
The payment-to-income ratio field is calculated based on the obligor's monthly self-reported gross income, including any income reported by a co-obligor.  The payment amount used in the calculation will not be reduced for refundable add on products. If the payment-to-income ratio field is omitted, the related receivable does not contain sufficient information to calculate the payment-to-income ratio or the related obligor is a business and does not have an individual co-obligor.
32 - Geographic location of obligor (Item 3(e)(7))
The geographic location of obligor field is populated with the last reported home address of the related obligor. Military postal codes including AA, AP and AE may be used in this field for those obligors with a related military address. Geographic location is based on the billing address of the obligors on the receivables.
33 - Asset added indicator (Item 3(f))(1))
This field will be marked "true" for all receivables in the report related to the month in which the closing date occurs.  It will generally be marked "false" for all receivables at all other times.
34 - Remaining term to maturity (Item 3(f)(2))
For both the initial period and subsequent monthly periods, the remaining term to maturity field is generated by counting the number of months from the month following the reporting period end date to, and including, the current maturity date of the related receivable.  The remaining term to maturity field is adjusted for any modifications to the final maturity of the receivable, including as a result of any extensions or due date changes. The methodology used to populate this field differs from the remaining term to maturity as disclosed in the prospectus, which treats the term as the number of contractually required monthly payments to maturity to be received from the related obligor.
35 - Modification indicator - reporting period (Item 3(f)(3))
The reporting period modification indicator field will be marked "true" for any receivable with respect to which there has been any modification to the original terms of the receivable in the reporting period, including the annual percentage rate, the amount financed and the term. Payment extensions as a result of a holiday, an administrative extension, a natural disaster or a reschedule will be reported as "true," in addition to required reductions under the Servicemembers Civil Relief Act of 2003.
37 - Reporting Period Beginning Loan Balance Amount (Item 3(f)(5))
The reporting period beginning loan balance amount field is populated using the amount financed of the related receivable at the beginning of the reporting period and is not the discounted receivables principal balance. The sum of the data points included for this field, except for receivables where a date is included in field 56, will equal the "Aggregate Receivables Face Amount-Beginning Balance" in section 5(A) of the Servicer Report.
38 - Next Reporting Period Payment Amount Due (Item 3(f)(6))
The next reporting period payment amount due field will be less than the monthly payment amount if the receivable is paid ahead.  If the amount in the field is equal to 0.00, no payment is due in the following month. If the receivable is past due, the amount in this field will be greater than the monthly payment amount for the receivable.  None of the fees accrued in connection with a late payment are included in this field.
39 - Reporting Period Interest Rate Percentage (Item 3(f)(7))
The reporting period interest rate percentage represents the interest rate that was effective at the beginning of the reporting period.
42 - Servicing fee - flat fee (Item 3(f)(10))
The servicing fee - flat fee field will be omitted because it is inapplicable.
43 - Other loan-level servicing fee(s) retained by servicer (Item 3(f)(11))
The supplemental servicing fees that are described below are not paid out of collections on the receivables and will not be included in the other loan-level servicing fee(s) retained by servicer field. The fees paid to the administrator do not relate to the loan-level servicing fees and are not included in this field.
Supplemental servicing fees include late fees, prepayment charges and other administrative fees and expenses collected during the month and investment earnings on the trust accounts.
44 - Other assessed but uncollected servicer fees (Item 3(f)(12))
The servicer will be entiltled to a supplemental servicing fee, which will not be paid out of collections, and will include late fees, prepayment charges and other administrative fees and expenses collected during the month and investment earnings on the trust accounts. Although supplemental servicing fees will not be payable to the issuing entity, the supplemental servicing fees are included in the other assessed but uncollected servicer fees field.  The fees included in this field represent the excess of cumulative fees charged since origination, including late charges and fees on active accounts over fees paid, fees waived, fees charged off and fees capitalized into the principal balance of the receivable.
45 - Scheduled Interest Amount (Item 3(f)(13))
The scheduled interest amount field is calculated for the initial period between the origination date and one month prior to the first payment due date based on the actual number of days elapsed during this period and a 365 day year and for each period thereafter, based on an amortization schedule created at loan origination based on the actual number of days in each month and a 365 day year. This field is not affected by any previous payment activity.
46 - Scheduled Principal Amount (Item 3(f)(14))
The scheduled principal amount field is calculated based on an amortization schedule determined at loan origination and is not affected by previous payment activity.
47 - Other Principal Adjustment Amount (Item 3(f)(15))
A negative number in the other principal adjustment amount field reflects an increasing principal balance. Prepayments will not be reflected in this field.  Any number in this field is only related to the reporting period and is not an aggregate amount outside of the reporting period.  If a payment is reversed, it will be reflected with a negative number in the amount of such reversal in this field.
48 - Reporting period ending actual balance (Item 3(f)(16))
The amount reported in the reporting period ending actual balance field for any receivables that have been paid in full or charged off will be 0.00 for the month in which it occurs.  For any month after a receivable has been paid in full or charged off, this field will be omitted. The sum of the data points included for this field, except for receivables where a date is included in field 56, will equal the "Aggregate Receivables Face Amount-Ending Balance" in section 5(A) of the Servicer Report.
49 - Reporting Period Scheduled Payment Amount (Item 3(f)(17))
The reporting period scheduled payment amount field is calculated based on an amortization schedule at loan origination and is not affected by previous payment activity and does not include any fees payable by the obligor. This field will generally equal the sum of fields 45 and 46 for each receivable.
50 - Total Actual Amount Paid (Item 3(f)(18))
For purposes of the total actual amount paid field, any warranty payments paid as a result of a repurchase of a receivable will not be included.  This field generally reflects the amount the issuing entity will receive from a payment on the receivable, which can include insurance proceeds related to a financed vehicle.  This field will generally will equal the sum of fields 51, 52 and 53 for each receivable.
51 - Actual Interest Collected Amount (Item 3(f)(19))
The actual interest collected amount is calculated based on the reporting period beginning loan balance amount and the reporting period interest percentage rate. The actual interest collected amount may differ from the reporting period scheduled interest payment. A zero in the actual interest collected amount field represents that (a) no payment was collected, (b) the reporting period interest percentage rate is 0.0%, or (c) the collections for the period resulted in a negative value (returned check with no offsetting collection amount). The sum of the amount shown in this field for each receivable and the sum of the amount shown in field 52 for each receivable will not equal the amount specified under "Receipts During the Period" in Section 4 of the Servicer Report due to the exclusion of the net negative values in this field.
52 - Actual Principal Collected Amount (Item 3(f)(20))
The actual principal collected amount is calculated based on the reporting period beginning loan balance amount, the reporting period interest percentage rate and the actual payment collected. The actual principal collected may differ from the reporting period scheduled principal payment. A zero in the actual principal collected amount field represents that (a) no payment was collected, (b) no portion of the collected payment applied to principal, or (c) the collections for the period resulted in a negative value (returned check with no offsetting collection amount). The sum of the amount shown in this field for each the amount specified under "Receipts During the Period" in Section 4 of the Servicer Report due to the exclusion of net negative values in this field.
53 - Actual Other Collected Amount (Item 3(f)(21))
The actual other collected amount reflects the portion of the collected payment applied to fees, including insufficient funds fees, late charges and extension fees. A zero in the actual other collected amount field indicates that either (a) no portion of the collected payment represented other collected amounts or (b) the collections representing other amounts netted to a negative value. All of these fees are retained by the servicer as supplemental servicing fees. The servicer is entitled to the supplemental servicing fees, which includes late fees, prepayment charges and other administrative fees and expenses collected during the month and investment earnings on the trust accounts. The sum of the amount shown in this field for each receivable will not equal the amount specified under "Supplemental Servicing Fees" in Section 4 of the Servicer Report due to exclusion or net negative values.
54 - Servicer advanced amount (Item 3(f)(22))
This field has been omitted because it is inapplicable.
55 - Interest Paid Through Date (Item 3(f)(23))
The interest paid through date is the date of the last applied payment with respect to a receivable and will not necessarily match the date interest is paid through for such receivable on a scheduled basis. If no payment was received during the reporting period, the interest paid through date reflects the date of the last applied payment.
56 - Zero balance loans - effective date (Item 3(f)(24)(i))
This field will be omitted until a loan balance has been reduced to zero.
The date specified in this field is the date the loan balance was reduced to zero during the reporting period.
57 - Zero balance loans - code(Items 3(f)(24)(II))
This field will be omitted until a loan balance has been reduced to zero.
The zero balance loans code will be reported following the reduction of a loan balance to zero during the reporting period. This code indicates the reason the loan balance was reduced to zero.
58 - Current delinquency status (Item 3(f)(25))
A "delinquent receivable" is a receivable for which payment of the required payment amount within $25 has not been received by the servicer by the payment due date as of the end of the monthly period. The number in the current deliquency status field reflects the number of days past due for a deliquent receivable. A zero in the current delinquency status field indicates a receivable is not a delinquent receivable. Charged off loans are not considered to be "delinquent receivables." The number in the current delinquency status field will be greater than zero but less than 30 prior to it being included in the Servicer Report because the Servicer Report does not report delinquencies until a payment is 30 days past due. If the number in the current delinquency status field is greater than 31, the sum of those receivables in each delinquency band will equal the "Delinquency Stratification-Total Accounts" in Section 6(B) of the Servicer Report, and the sum of the reporting period ending actual balance in field 48, except for receivables where a date is included in field 56, will equal the "Delinquency Stratification-Total Balance" in Section 6(B) of the Servicer Report.
60 - Most Recent Servicing Transfer Received Date (Item 3(g)(2))
This field will be omitted because the servicer has continuously serviced each of the receivables since the related origination date and no servicing transfer has occurred.
61 - Asset Subject to Demand (Item 3(h))
A "true" in the asset subject demand indicator field indicates a receivable is subject to a third party repurchase demand. All other receivables, including those receivables subject to voluntary, administrative or servicer repurchases, will be marked "false."
62 - Status of asset subject to demand (Item 3(h)(1))
This field will be omitted until a demand by a third party to repurchase receivables is received.
The asset subject demand status code will be reported following a third party repuchase demand. A "98" in the asset subject demand status code field indicates a third party repurchase demand that has been made and is being processed or investigated.
63 - Repurchase Amount (Item 3(h)(2))
This field will be omitted until a demand by a third party to repurchase receivables is received.
The repurchase amount will be reported following a third party repurchase demand. A zero in the repuchase amount field indicates that the related third party repuchase demand is pending, in dispute or being processed or investigated, or that such demand has been rejected or withdrawn.
64 - Demand Resolution Date (Item 3(h)(3))
This field will be omitted until a demand by a third party to repurchase is received.
The demand resolution date will be reporting following a third party repurchase demand. The date in the demand resolution date field reflects the date that the related receivable was repuchased or replaced or that the third party repurchase demand was withdrawn or rejected. A zero in the demand resolution date field indicates that the related third party repurchase demand is pending, in dispute or being processed or investigated.
65 - Repurchaser (Item 3(h)(4))
This field will be omitted until a demand by a third party to repurchase receivables is received.
This field specifies the name of the third party who has demanded a repurchase of receivables.
66 - Repurchase or Replacement Reason(Item 3(h)(5))
This field will be omitted until a demand by a third party to repurchase receivables for a breach of representations and warranties is received and code "98" or "99" is used in field 62.
67 - Charged off Principal Amount (Item 3(i)(1))
The charged off principal amount field reflects the amount of principal charged off with respect to the receivable during the current reporting period, net of applicable liquidation expenses and other out-of-pocket costs related to liquidation, not to exceed $300 per receivable or such greater amount as the servicer determines necessary in accordance with its customary procedures to refurbish and dispose of a financed vehicle. The sum of teh data points included for this field, except for receivables where a date is included in field 56, will equal the "Charge-Off Rate-Net Charge-Offs-Current" in section 6(A) of the Servicer Report.
68 - Amounts Recovered (Item 3(i)(2))
The amounts recovered field reflects all amounts received from the obligors for a charged-off receivable during the current reporting period. The sum of the amount shown in this field for each receivable and the sum of the amount shown in field 72 for each receivable will equal the amound of specified under "Liquidation Proceeds (Recoveries) Less Liquidation Expenses" in Section 4 of teh Servicer Report.
69 - Modification Type Code (Item 3(j)(1))
For a receivable modified pursuant to the Servicemembers Civil Relief Act of 2003, the modification type code "1" is used. For a fully rewritten receivable, the modification type code "1, 3" is used. If the modification type code includes a "1," "2" or "3," the related receivable will be repurchased during the following reporting period.  Generally the servicer will repurchase a receivable modified to comply with the Servicemembers Civil Relief Act of 2003.
70 - Payment Extension (Item 3(j)(2))
This field indicates the number of months a loan was extended during the reporting period.
71 - Repossessed (Item 3(k)
A "true" in the repossessed indicator field indicates that a vehicle has been repossessed during the current reporting period or during a prior reporting period. If a receivable is reinstated after the related vehicle is repossessed, a "false" will be in the repossessed indicator field.
72 - Repossessed Proceeds Amount (Item 3(k)(1))
The repossessed proceeds amount field reflects the amount of proceeds with respect to a repossessed vehicle received during the current reporting period, including insurance proceeds, net of related fees and liquidation expenses. The sum of the amount shown in this field for each receivable and the sum of the amount shown in field 68 for each receivable will equal the amount specified under "Liquidation Proceeds (Recoveries) Less Liquidation Expenses" in Section 4 of the Servicer Report.
