Item 1115(b) of Regulation AB, Certain Derivatives Instruments (Financial

No entity or group of affiliated entities provides any derivative

as described under Item 1115 of Regulation AB.


Item 1117 of Regulation AB, Legal Proceedings.

The registrant knows of no material pending legal proceeding involving the
trust or any party related to the trust, other than routine litigation
incidental to the duties of those respective parties, and the following,
with respect to Deutsche Bank Trust Company Americas, as trustee,
certificate administrator and custodian.

Deutsche Bank Trust Company Americas ("DBTCA") and Deutsche Bank National
Trust Company ("DBNTC") have been sued by investors in civil litigation
concerning their role as trustees of certain RMBS trusts.

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. 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. 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. 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 Trustee, Certificate Administrator and Custodian under the
Pooling and Servicing Agreement for this transaction.


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

The information regarding this Item has been previously provided in a
prospectus supplement of the Registrant relating to the issuing entity
filed on September 26, 2012 pursuant to Rule 424(b)(5).

The reports on assessments of compliance with the servicing criteria for
asset-backed securities and related attestation reports on such assessments
of compliance with respect to the mortgage loans are attached hereto under
Item 15 to this Annual Report on Form 10-K. Attached as Schedule II to the
Pooling and Servicing Agreement incorporated by reference as Exhibit 4 to
this Annual Report on Form 10-K is a chart identifying the entities
participating in a servicing function for the transaction responsible for
each applicable servicing criteria set forth in Item 1122(d).
