**Item 1117 of Regulation AB, Legal Proceedings.**

The registrant knows of no material pending legal proceedinginvolving the trust or any party related to the trust, other than routinelitigation incidental to the duties of those respective parties, and thefollowing, with respect to Wells Fargo Bank, National Association, as trustee,certificate administrator and custodian, and RAIT Funding, LLC, as loan seller:

Since June 18, 2014, a group of institutional investors havefiled civil complaints in the Supreme Court of the State of New York, New YorkCounty, and later the U.S. District Court for the Southern District of New Yorkagainst Wells Fargo Bank, N.A., (“Wells Fargo Bank”) in its capacity as trusteefor certain residential mortgage backed securities (“RMBS”) trusts.  The complaintsagainst Wells Fargo Bank alleged that the trustee caused losses to investorsand asserted causes of action based upon, among other things, the trustee'salleged failure to: (i) notify and enforce repurchase obligations of mortgageloan sellers for purported breaches of representations and warranties, (ii)notify investors of alleged events of default, and (iii) abide by appropriatestandards of care following alleged events of default. Relief sought includedmoney damages in an unspecified amount, reimbursement of expenses, andequitable relief. Wells Fargo Bank has reached an agreement, in which it deniesany wrongdoing, to resolve these claims on a classwide basis for the 271 RMBStrusts currently at issue.  The settlement agreement is subject to courtapproval.  Separate lawsuits against Wells Fargo Bank making similarallegations filed by certain other institutional investors concerning 57 RMBStrusts in New York federal and state court are not covered by theagreement.  With respect to the foregoing litigations, Wells Fargo Bankbelieves plaintiffs' claims are without merit and intends to contest the claimsvigorously, but there can be no assurances as to the outcome of the litigationsor the possible impact of the litigations on Wells Fargo Bank or the RMBStrusts.

On September 20, 2017, RAIT Preferred Funding II, Ltd., orRAIT II, filed an amended complaint against CWCapital Asset Management, LLC, orCWCapital, Wells Fargo Bank N.A., or Wells Fargo, and U.S. Bank N.A., or U.S.Bank. This action concerns a loan, or the mortgage loan, to a non-partyborrower, or the borrower, in 2007.  RAIT II purchased $18,500,000 of themortgage loan for which it held a promissory note, or note B.  U.S. Bankis the trustee for a securitization trust that purchased the remaining$190,000,000 of the mortgage loan and for which it held a promissory note, ornote A.  CWCapital is the special servicer and Wells Fargo is the masterservicer for the mortgage loan (including note A and note B).  Theparties’ rights and obligations are governed by, among other things, a poolingand servicing agreement and a co-lender agreement.  The mortgage loan wasrepaid in May of 2017, and the defendants have alleged that RAIT II was notentitled to receive any payoff of principal under note B pursuant to thesubordination and other provisions of the co-lender agreement.  In theamended complaint, RAIT II alleges, among other things, that the defendantsbreached certain of its obligations under the operative documents and RAIT IIshould have received, among other things, all of its $18.5 million principalunder note B.  The court denied defendants’ motion to dismiss RAIT II’samended complaint, and the parties are now in the midst of the discovery phaseof the litigation.  RAIT Partnership, L.P. served as the collateralmanager and servicer for RAIT II.  

**Item 1119 of Regulation AB, Affiliations and CertainRelationships and Related Transactions.**

The information regarding this Item has been previouslyprovided in a prospectus supplement of the Registrant relating to the issuingentity filed on August 28, 2015 pursuant to Rule 424(b)(5).

**Item 1122 of Regulation AB, Compliance with ApplicableServicing Criteria.**

The reports on assessments of compliance with the servicingcriteria for asset-backed securities and related attestation reports on suchassessments of compliance with respect to the mortgage loans are attachedhereto under Item 15 to this Annual Report on Form 10-K.

The reports on assessments of compliance with the servicingcriteria for asset-backed securities and related attestation reports on suchassessments of compliance with respect to the Brunswick Portfolio MortgageLoan, which is being serviced and administered pursuant to the pooling andservicing agreement for the JPMBB 2015-C30 Transaction, are attached heretounder Item 15 to this Annual Report on Form 10-K.

The report on assessment of compliance with applicableservicing criteria furnished pursuant to Item 1122 of Regulation AB by MidlandLoan Services, a Division of PNC Bank National Association discloses that amaterial instance of noncompliance occurred, as described below:

Material Instance of Noncompliance

In certain instances, the ScheduleAL Files (Item 1125 of Regulation AB) were not reported in accordance with theterms specified in the transaction agreements, in conflict with Item1122(d)(3)(i): “Reports to investors, including those to be filed with theCommission, are maintained in accordance with the transaction agreements andapplicable Commission requirements. Specifically, such reports: (A) Areprepared in accordance with timeframes and other terms set forth in thetransaction agreements”.  The noncompliance consisted of omitted orinaccurately reported numbers due to the following: (1) the initial setup filescontained information at the asset level, and Midland was required to manuallycompile the information to present it at the loan level as required by ScheduleAL; and (2) certain reporting requirements required manual processing byMidland, including the use of various data computation formulas, qualitycontrol checks and analysis.

The identified instances did notinvolve the servicing of assets included in this securitization.

Steps Taken to Remedy the Material Instance of Noncompliance

Midland is currently remediating theSchedule AL reporting for the CMBS transactions found to be incorrect, and willbe making improvements to its systems, processes and procedures to support itsSchedule AL reporting obligations.
