On June 18, 2014, a group of investors, including funds managed by Blackrock Advisors, LLC,
PIMCO-Advisors, L.P., and others, filed a derivative action against DBNTC and DBTCA in New York State Supreme Court purportedly on behalf of and for the benefit of 544 private-label RMBS trusts asserting claims for alleged violations of the U.S.
Trust Indenture Act of 1939 (TIA), breach of contract, breach of fiduciary duty and negligence based on DBNTC and DBTCAs alleged failure to perform their duties as trustees for the trusts. Plaintiffs subsequently dismissed their state court
complaint and filed a derivative and class action complaint in the U.S. District Court for the Southern District of New York on behalf of and for the benefit of 564 private-label RMBS trusts, which substantially overlapped with the trusts at issue
in the state court action. The complaint alleges that the trusts at issue have suffered total realized collateral losses of U.S. $89.4 billion, but the complaint does not include a demand for money damages in a sum certain. DBNTC and DBTCA
filed a motion to dismiss, and on January 19, 2016, the court partially granted the motion on procedural grounds: as to the 500 trusts that are governed by Pooling and Servicing Agreements, the court declined to exercise jurisdiction. The court
did not rule on substantive defenses asserted in the motion to dismiss. On March 22, 2016, plaintiffs filed an amended complaint in federal court. In the amended complaint, in connection with 62 trusts governed by indenture agreements,
plaintiffs assert claims for breach of contract, violation of the TIA, breach of fiduciary duty, and breach of duty to avoid conflicts of interest. The amended complaint alleges that the trusts at issue have suffered total realized collateral losses
of U.S. $9.8 billion, but the complaint does not include a demand for money damages in a sum certain. On July 15, 2016, DBNTC and DBTCA filed a motion to dismiss the amended complaint. On January 23, 2017, the court granted in part
and denied in part DBNTC and DBTCAs motion to dismiss. The court granted the motion to dismiss with respect to plaintiffs conflict-of-interest claim, thereby
dismissing it, and denied the motion to dismiss with respect to plaintiffs breach of contract claim (except as noted below) and claim for violation of the TIA, thereby allowing those claims to proceed. On January 26, 2017, the parties
filed a joint stipulation and proposed order dismissing plaintiffs claim for breach of fiduciary duty. On January 27, 2017, the court entered the parties joint stipulation and ordered that plaintiffs claim for breach of
fiduciary duty be dismissed. On February 3, 2017, following a hearing concerning DBNTC and DBTCAs motion to dismiss on February 2, 2017, the court issued a short form order dismissing (i) plaintiffs representation and
warranty claims as to 21 trusts whose originators and/or sponsors had entered bankruptcy and the deadline for asserting claims against such originators and/or sponsors had passed as of 2009 and (ii) plaintiffs claims to the extent they
were premised upon any alleged pre-Event of Default duty to terminate servicers. On March 27, 2017, DBNTC and DBTCA filed an answer to the amended complaint. On January 26, 2018, Plaintiffs filed a
motion for class certification. DBNTC and DBTCAs opposition to Plaintiffs motion is due on March 26, 2018, and Plaintiffs reply is due on April 16, 2018. Discovery is ongoing.

On March 25, 2016, the BlackRock plaintiffs filed a state court action against DBTCA in the Superior Court of California, Orange
County with respect to 513 trusts. On May 18, 2016, plaintiffs filed an amended complaint with respect to 465 trusts, and included DBNTC as an additional defendant. The amended complaint asserts three causes of action: breach of
contract; breach of fiduciary duty; and breach of the duty to avoid conflicts of interest. Plaintiffs purport to bring the action on behalf of themselves and all other current owners of certificates in the 465 trusts. The amended complaint
alleges that the trusts at issue have suffered total realized collateral losses of U.S. $75.7 billion, but does not include a demand for money damages in a sum certain. On August 22, 2016, DBNTC and DBTCA filed a demurrer as to
Plaintiffs breach of fiduciary duty cause of action and breach of the duty to avoid conflicts of interest cause of action and motion to strike as to Plaintiffs breach of contract cause of action. On October 18, 2016, the court
granted DBNTC and DBTCAs demurrer, providing Plaintiffs with thirty days leave to amend, and denied DBNTC and DBTCAs motion to strike. Plaintiffs did not further amend their complaint and, on December 19, 2016, DBNTC and DBTCA
filed an answer to the amended complaint. On January 17, 2018, Plaintiffs filed a motion for class certification. DBNTC and DBTCAs opposition to Plaintiffs motion is due on March 16, 2018, and Plaintiffs reply is due on
April 16, 2018. Discovery is ongoing.

On September 27, 2017, DBTCA was added as a defendant to a case brought by certain special
purpose entities including Phoenix Light SF Limited in the U.S. District Court for the Southern District of New York, in which the plaintiffs previously alleged incorrectly that DBNTC served as trustee for all 43 of the trusts at issue. On
September 27, 2017, plaintiffs filed a third amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee for one of the 43 trusts at issue. DBNTC serves as trustee for the other 42 trusts at issue.
Plaintiffs third amended complaint brings claims for violation of the TIA; breach of contract; breach of fiduciary duty; negligence and gross negligence; violation of the Streit Act; and breach of the covenant of good faith. However, in the
third amended complaint, plaintiffs acknowledge that, before DBTCA was added to the case, the court dismissed plaintiffs TIA Act claims, negligence and gross negligence claims, Streit Act claims, claims for breach of the covenant of good
faith, and certain theories of plaintiffs breach of contract claims, and plaintiffs only include these claims to preserve any rights on appeal. Plaintiffs allege damages of hundreds of millions of dollars. On November 13,
2017, DBNTC and DBTCA filed an answer to the third amended complaint. Discovery is ongoing.

On November 30, 2017, DBTCA was added as
a defendant to a case brought by Commerzbank AG (Commerzbank) in the U.S. District Court for the Southern District of New York, in which Commerzbank previously alleged incorrectly that DBNTC served as trustee for all 50 of the trusts at
issue.

---

On November 30, 2017, Commerzbank filed a second amended complaint that names DBTCA as a
defendant in addition to DBNTC. DBTCA serves as trustee for 1 of the 50 trusts at issue. DBNTC serves as trustee for the other 49 trusts at issue. Commerzbanks second amended complaint brings claims for violation of the TIA; breach of
contract; breach of fiduciary duty; negligence; violation of the Streit Act; and breach of the covenant of good faith. However, in the second amended complaint, Commerzbank acknowledges that, before DBTCA was added to the case, the court dismissed
Commerzbanks TIA claims for the trusts governed by pooling and servicing agreements, as well as its Streit Act claims and claims for breach of the covenant of good faith, and Commerzbank only includes these claims to preserve any rights on
appeal. The second amended complaint alleges that DBNTC and DBTCA caused Commerzbank to suffer hundreds of millions of dollars in losses, but the complaint does not include a demand for money damages in a sum certain. On January 29,
2018, DBNTC and DBTCA filed an answer to the second amended complaint. Discovery is ongoing.

On December 30, 2015, IKB International,
S.A. in Liquidation and IKB Deutsche Industriebank A.G. (collectively, IKB), as an investor in 37 RMBS trusts, filed a summons with notice in the Supreme Court of the State of New York, New York County, against DBNTC and DBTCA as
trustees of the trusts. On May 27, 2016, IKB served its complaint asserting claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, violation of New Yorks Streit Act, violation of the
Trust Indenture Act, violation of Regulation AB, and violation of Section 9 of the Uniform Commercial Code. IKB alleges that DBNTC and DBTCA are liable for over U.S. $268 million in damages. On October 5, 2016, DBNTC and DBTCA,
together with several other trustees defending lawsuits by IKB, filed a joint motion to dismiss. On January 6, 2017, IKB filed a notice of discontinuance, voluntarily dismissing with prejudice all claims as to three trusts. As of
January 17, 2017, DBNTC and DBTCAs motion to dismiss has been briefed and is awaiting decision by the court. On June 20, 2017, the parties filed a stipulation, voluntarily dismissing with prejudice all claims as to four additional
trusts. Certain limited discovery is permitted to go forward while the motion to dismiss is pending.

It is DBTCAs belief that it has
no pending legal proceedings (including, based on DBTCAs present evaluation, the litigation disclosed in the foregoing paragraphs) that would materially affect its ability to perform its duties as indenture trustee under the Indenture and Sale
and Servicing Agreement for this transaction.

Substitute information provided in accordance with General
Instruction J to Form 10-K:

Item 1119 of Regulation AB. Affiliations and Certain
Relationships and Related Transactions.

Information required by Item 1119 of Regulation AB has been omitted from this report on Form 10-K in reliance on the Instruction to Item 1119.

Item 1122 of Regulation AB. Compliance with
Applicable Servicing Criteria.

Each of SC, the Subservicer and Deutsche Bank Trust Company Americas (each, a Servicing
Participant) have been identified by the issuing entity as parties participating in the servicing function with respect to the pool assets held by the issuing entity. Each of the Servicing Participants has completed a report on an
assessment of compliance with the servicing criteria applicable to it (each, a Report on Assessment), which Reports on Assessment are attached as exhibits to this Form 10-K. In addition, each
of the Servicing Participants has provided an attestation report (each, an Attestation Report) by one or more registered public accounting firms, which reports are also attached as exhibits to this Form
10-K.

Managements Assessment of Compliance for SC has identified material instances of
noncompliance for the 2017 fiscal year, one of which is a continuation of a material instance of noncompliance reported by the issuing entity in its annual report on Form 10-K filed March 30, 2017 and
relates to reports to investors delivered during or prior to March 2017.

Managements Assessment of Compliance for SC for the 2016
fiscal year identified a material instance of noncompliance related to the servicing criterion set forth in Item 1122(d)(3)(i)  reports to investors, including those to be filed with the Commission, were not maintained in accordance with the
transaction agreements and applicable Commission requirements. Specifically, reports to investors provided information that was not calculated in accordance with the terms specified in the transaction agreements. SC determined the existence of a
material instance of noncompliance in March 2017, and the material instance of noncompliance related to this instance for the 2017 fiscal year relates to reports to investors delivered during or prior to March 2017. The instance of noncompliance
described in this paragraph for both the 2016 and 2017 fiscal years, which does relate to the asset-backed securities covered in this Form 10-K and issued by the issuing entity, relates to two separate
matters:

Under the transaction agreements for the Platform, SC, as Servicer, is entitled to receive all Supplemental Servicing Fees as
additional servicing compensation, and such Supplemental Servicing Fees do not constitute Available Funds. However, SC included Supplemental Servicing Fees for certain transactions in the Platform under other amounts received and
included such amounts as part of Available Funds in the investor reports; for these transactions, Supplemental Servicing Fees were distributed in accordance with the payment priorities set forth in the related transaction agreements
rather than being retained by the Servicer.



6



---

To address this issue related to Supplemental Servicing Fees and the related instance of
noncompliance, SC stopped including Supplemental Servicing Fees as other amounts received for all transactions in the Platform beginning with the March 2017 collection period and began retaining such amounts as additional servicing
compensation as specified in the transaction agreements. SC believes that the inclusion of Supplemental Servicing Fees as available funds did not result in any material adverse effect on security holders.

Under the transaction agreements for the Platform, SC, as Servicer, is required to pay all expenses incurred by it in connection with its
activities as servicer other than expenses in connection with the sale of a repossessed vehicle, which may be netted from liquidation proceeds from such sale. For certain transactions in the Platform, SC did not net external costs associated
with repossession expenses attributable to financed vehicles sold after the related receivables have become defaulted receivables; for these transactions, SC paid such repossession expenses and the Liquidation Proceeds included in the
investor reports and distributed in accordance with the payment priorities set forth in the related transaction agreements were greater than they would have been had SC reduced the liquidation proceeds by the external costs associated with
repossession expenses in accordance with the transaction agreements for those transactions.

To address this issue related to repossession
expenses and the related instance of noncompliance, SC amended the transaction agreements for the effected transactions in the Platform to memorialize the agreement of the Servicer to pay such external costs of repossessions rather than netting such
amounts from sale proceeds from the disposition of repossessed financed vehicles. SC believes that the payment of external costs associated with repossession expenses by the Servicer and the failure to report Liquidation Expenses on the
investor reports net of such repossession expenses for certain transactions did not result in any material adverse effect on security holders.

Managements Assessment of Compliance for SC for the 2017 fiscal year identified an additional matter that resulted in a finding of a
material instance of noncompliance related to the servicing criterion set forth in Item 1122(d)(3)(i)  reports to investors, including those to be filed with the Commission, were not maintained in accordance with the transaction agreements and
applicable Commission requirements and Item 1122(d)(4)(iii)  any additions, removals or substitutions to the asset pool are made, reviewed and approved in accordance with any conditions or requirements in the transaction agreements. This
matter relates to the following circumstance:

The transaction agreements for each transaction in the Platform specify the repurchase price
to be paid by SC in connection with the repurchase of receivables from the issuing entity. In August 2017, the Servicer recalculated the accrued interest portion of the repurchase price paid in connection with the prior repurchase of receivables
from issuers included in the Platform and, after recalculating the amount of accrued interest owed, determined that there was an aggregate shortfall in the repurchase price paid for certain of the transactions in the Platform. The material instance
of noncompliance described in this paragraph does relate to the asset-backed securities covered by this Form 10-K and issued by the issuing entity.

To address this issue related to the repurchase price for receivables and the related instances of noncompliance, SC recalculated the
repurchase price for all affected transactions and made deposits on August 15, 2017 into the applicable collection account in an amount equal to the shortfall. Additionally, SC updated the related systems coding applicable to the methodology
for calculating the repurchase price in August 2017 to avoid future shortfalls. SC believes that the shortfall in the accrued interest portion of the repurchase price paid in connection with the prior repurchase of receivables and the subsequent
deposit of the shortfall into the applicable collection account did not result in any material adverse effect on security holders.



7



---

With respect to the instances of noncompliance described above, SC has implemented additional
procedures to confirm that calculations included in investor reports are completed as set forth in the transaction agreements and has implemented greater management oversight of reporting, enhanced quality assurance controls, and updated the related
systems coding applicable to calculations included in investor reports.

Item 1123 of Regulation AB. Servicer Compliance
Statements.

SC and the Subservicer have been identified by the issuing entity as the servicers with respect to the asset pool held by
the issuing entity. Each of SC and the Subservicer have completed a statement of compliance with applicable servicing criteria (each, a Compliance Statement) signed by an authorized officer. The Compliance Statements are
attached as exhibits to this Form 10-K.
