EXPLANATORY NOTES
Wells Fargo Bank, National Association, as Master Servicer of the subject
transaction did not provide an assessment of compliance with respect to Item
1122(d)(3)(iii). At the time the Pooling and Servicing Agreement was
entered into, it was intended that either the master servicer or the certificate
administrator would perform this servicing function.  In fact, Item
1122(d)(3)(iii) of Regulation AB was performed by the certificate
administrator, and is included in the assessment of compliance with
applicable servicing criteria and accountants' attestation report of the
certificate administrator for the subject transaction.

U.S. Bank National Association acts as trustee of the mortgage loans
serviced under the Pooling and Servicing Agreement.  Pursuant to the
Pooling and Servicing Agreement, the trustee is required to provide an
assessment of compliance with applicable servicing criteria solely with
respect to Item 1122(d)(2)(iii) of Regulation AB (regarding advances of
funds or guarantees regarding collections, cash flows or distributions, and
any interest or other fees charged for such advances, are made, reviewed and
approved as specified in the transaction agreements).  However, during the
reporting period, the trustee did not perform any servicing function with
respect to the servicing criteria specified in Item 1122(d)(2)(iii) of
Regulation AB.  The master servicer or the special servicer, to the extent
required, performed the servicing function identified with respect to Item
1122(d)(2)(iii) of Regulation AB, and each such party included Item
1122(d)(2)(iii) of Regulation AB in the assessment of compliance with
applicable servicing criteria and accountant's attestation report for the
subject transaction.  As a result, this Annual Report on Form 10-K does not
include an assessment of compliance with applicable servicing criteria of the
trustee. One or more other servicers of the mortgage loans serviced under the
Pooling and Servicing Agreement have delivered one or more assessments of
compliance with respect to Item 1122(d)(2)(iii) of Regulation AB.

This Annual Report on Form 10-K includes assessments of compliance with
applicable servicing criteria and accountants' attestation reports from
CoreLogic Commercial Real Estate Services, Inc. and National Tax Search,
LLC.  These entities were engaged by the master servicer under the Pooling
and Servicing Agreement to remit tax payments received from the escrow
accounts of borrowers to local taxing authorities, to report tax amounts due,
to verify tax parcel information, and to verify non-escrow tax payments.
These servicing functions are included within the servicing criteria set forth
in Items 1122(d)(4)(xi) and 1122(d)(4)(xii) of Regulation AB.  Therefore,
under the principles-based definition of "servicer" set forth in Item 1101(j)
of Regulation AB that looks to the functions that an entity performs, these
vendors are "servicers" for the purposes of Item 1122 of Regulation AB.  See
Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

In August and September 2016, actions were taken intended to terminate Rialto
Capital Advisors, LLC ("Rialto") as special servicer and to appoint
KeyBank National Association ("KeyBank") as successor special servicer
under the Pooling and Servicing Agreement. On September 13, 2016,
Rialto received notice from the Trustee that it had been terminated as
special servicer and that KeyBank had been appointed as replacement
special servicer, effective as of September 12, 2016. Consistent with that
notice, the name of the special servicer was changed by the Certificate
Administrator from Rialto to KeyBank on the monthly distribution date
statements attached to the monthly Asset-Backed Issuer Distribution
Reports on Form 10-D for the months of October, November and December 2016
and January 2017. While conducting its due diligence in connection with the
preparation of this Annual Report on Form 10-K for the 2016 reporting period,
the registrant determined that certain of the documents required for such
termination and appointment, including notices, legal opinions and
disclosures, were, in fact, missing, defective or otherwise failed to
satisfy the requirements of the Pooling and Servicing Agreement.

On February 9, 2017, Rialto was advised that, through no fault of Rialto,
the requirements of the Pooling and Servicing Agreement relating to its
replacement had not been satisfied. Rialto was, and has been, Special
Servicer under the Pooling and Servicing Agreement since replacing
CWCapital Asset Management LLC as Special Servicer on October 7, 2014.
Accordingly, the monthly distribution date statement attached to the
monthly Asset-Backed Issuer Distribution Reports on Form 10-D for February
2017 indicated that Rialto, not KeyBank, was the special servicer of
the issuing entity. On March 8, 2017, the registrant and the other relevant
parties executed a Notice and Acknowledgement acknowledging that
any attempted termination of Rialto as special servicer and appointment of
KeyBank as successor special servicing failed to satisfy the requirements
of the Pooling and Servicing Agreement, and thus no such termination and
appointment occurred. On March 24, 2017, the Trustee delivered a notice of
rescission of notice of special servicer replacement rescinding its
September 13, 2016 notice. The registrant subsequently filed amended
monthly Asset-Backed Issuer Distribution Reports on Form 10-D/As for the
months of October, November, and December 2016 and January 2017 indicating
that Rialto, not KeyBank was the special servicer during those monthly
reporting periods.

Rialto's report on assessment of compliance with servicing criteria for
asset-backed securities, and servicer compliance statement, and the
attestation report on assessment of compliance with servicing criteria for
asset-backed securities of Rialto's accountants for the reporting period are
included in this Annual Report on Form 10-K as Exhibits 33.2, 35.2 and 34.2,
respectively. As indicated in such exhibits, Rialto took such actions as
were necessary to provide such exhibits. No Servicing Transfer Events
occurred during the period September 12, 2016 through December 31,
2016; there were no Specially Serviced Loans included in the issuing
entity at the commencement of, or during such period. KeyBank has advised
the registrant that during such period, the only action taken by KeyBank
as purported Special Servicer was a consent to a lease amendment
respecting a J.C. Penney Lease relating to the Plaza de Sol Loan. KeyBank
did not receive any compensation under the Pooling and Servicing
Agreement for giving such consent. KeyBank provided Rialto with the
relevant materials applicable to such consent. On March 29, 2017, the
registrant delivered a notice, acknowledged by Rialto, to the Master
Servicer, informing the Master Servicer that Rialto concurred in and
ratified the consent action taken by KeyBank.

To ensure compliance with the applicable reporting requirements of the
Securities Exchange Act of 1934, as amended, with respect to future
transfers of special servicing, the Certificate Administrator has agreed
with the registrant (i) that the Certificate Administrator will forward to
the registrant any notices it receives regarding any transfer or proposed
transfer of special servicing, including notices from a directing holder,
and (ii) to expand and clearly define the roles of the personnel at the
Certificate Administrator who receive information relating to transfers
or proposed transfers of special servicing, and instruct them how and
when to forward any such information to the registrant.

The Square One Mall Mortgage Loan (Loan Number 1 on Annex A-1 of the

period ended December 31, 2016.

Item 1114(b)(2) of Regulation AB, Significant Enhancement Provider Financial

as described under Item 1114(a) of Regulation AB.


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

No entity or group of affiliated entities provides any derivative
instruments or other support for the certificates within this transaction
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 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 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 March 19, 2012 pursuant to Rule 424(b)(5).

asset-backed securities and related attestation reports on such
assessments of compliance with respect to the mortgage loans are attached
