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 (except with respect to those mortgage loans for which Midland Loan Services, a
Division of PNC Bank, National Association is the primary servicer)  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.SeeCompliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

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 U.S. Bank National Association, as trustee, and Wells Fargo Bank, National Association, as certificate administrator and custodian:

Since 2014 various plaintiffs or groups of plaintiffs, primarily investors, have filed claims against U.S. Bank National Association (“U.S. Bank”),
in its capacity as trustee or successor trustee (as the case may be) under certain residential mortgage-backed securities ("RMBS") trusts.  The plaintiffs or plaintiff groups have filed substantially similar complaints against other RMBS trustees,
including Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and Wells Fargo.  The complaints against U.S. Bank allege the trustee caused losses to investors as a result of alleged failures by the sponsors, mortgage loan sellers and servicers
for these RMBS trusts and assert causes of action based upon the trustee's purported failure to enforce repurchase obligations of mortgage loan sellers for alleged breaches of representations and warranties concerning loan quality.  The complaints
also assert that the trustee failed to notify securityholders of purported events of default allegedly caused by breaches of servicing standards by mortgage loan servicers and that the trustee purportedly failed to abide by a heightened standard of care
following alleged events of default.

Currently U.S. Bank is a defendant in multiple actions alleging individual or class action claims against the trustee with respect to multiple trusts as
described above with the most substantial case being:BlackRock Balanced Capital Portfolioet al v. U.S. Bank National Association, No. 605204/2015 (N.Y. Sup. Ct.) (class action alleging claims with
respect to approximately 770 trusts) and its companion caseBlackRock Core Bond Portfolio et al v. U.S Bank National Association, No. 14-cv-9401 (S.D.N.Y.).  Some of the trusts implicated in the aforementioned Blackrock cases, as well as other trusts, are involved in actions brought by separate groups of plaintiffs related to no more than 100
trusts per case.

U.S. Bank cannot assure you as to the outcome of any of the litigation, or the possible impact of these litigations on the trustee or the RMBS trusts. However,
U.S. Bank denies liability and believes that it has performed its obligations under the RMBS trusts in good faith, that its actions were not the cause of losses to investors and that it has meritorious defenses, and it intends to contest the
plaintiffs’ claims vigorously.

On June 18, 2014, a group of institutional investors filed a civil complaint in the Supreme Court of the State
of New York, New York County, against Wells Fargo Bank, N.A. (“Wells Fargo Bank”) in its capacity as trustee under 276 residential mortgage backed securities (“RMBS”) trusts, which was later amended on July 18, 2014, to increase
the number of trusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motion to voluntarily dismiss the state court action without prejudice. That same day, a group of institutional investors filed a putative class action complaint in the
United States District Court for the Southern District of New York (the “District Court”) against Wells Fargo Bank, alleging claims against the bank in its capacity as trustee for 274 RMBS trusts (the “Federal Court Complaint”).
In December 2014, the plaintiffs’ motion to voluntarily dismiss their original state court action was granted. As with the prior state court action, the Federal Court Complaint is one of six similar complaints filed contemporaneously against RMBS
trustees (Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and US Bank) by a group of institutional investor plaintiffs. The Federal Court Complaint against Wells Fargo Bank alleges that the trustee caused losses to investors and asserts causes of
action based upon, among other things, the trustee's alleged failure to: (i) notify and enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, (ii) notify investors of alleged events of default,
and (iii) abide by appropriate standards of care following alleged events of default. Relief sought includes money damages in an unspecified amount, reimbursement of expenses, and equitable relief. Other cases alleging similar causes of action have been
filed against Wells Fargo Bank and other trustees in the District Court by RMBS investors in these and other transactions, and these cases against Wells Fargo Bank are proceeding before the same District Court judge. A similar complaint was also filed
May 27, 2016 in New York state court by a different plaintiff investor. On January 19, 2016, an order was entered in connection with the Federal Court Complaint in which the District Court declined to exercise jurisdiction over 261 trusts at issue in the
Federal Court Complaint; the District Court also allowed plaintiffs to file amended complaints as to the remaining, non-dismissed trusts, if they so chose, and three amended complaints have been filed. On December 17, 2016, the investor plaintiffs in the
261 trusts dismissed from the Federal Court Complaint filed a new complaint in New York state court (the “State Court Complaint”). In September 2017, Royal Park Investments SA/NV (“Royal Park”), one of the plaintiffs in the
District Court cases against Wells Fargo Bank, filed a putative class action complaint relating to two trusts seeking declaratory and injunctive relief and money damages based on Wells Fargo Bank’s indemnification from trust funds for legal fees
and expenses Wells Fargo Bank incurs or has incurred in defending the District Court case filed by Royal Park. With respect to the foregoing litigations, Wells Fargo Bank believes plaintiffs' claims are without merit and intends to contest the claims
vigorously, but there can be no assurances as to the outcome of the litigations or the possible impact of the litigations on Wells Fargo Bank or the RMBS trusts.

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 June 26,
2012 pursuant to Rule 424(b)(5).
