10-K) and (ii) replace the attestation report of NDNB Assurance LLP on Rialto Capital Advisors, LLC’s assessment of compliance with the servicing criteria for asset-backed securities with the attestation report of Deloitte & Touche LLP, dated

other changes have been made to the Original Form 10‐K.  This Amendment No. 1 does not reflect subsequent events occurring after the original filing date of the Original Form 10-K.



The MSC 2015-UBS8 mortgage pool includes the following mortgage loans, each of which is serviced pursuant to
a separate pooling and servicing agreement (each, an “Outside Pooling and Servicing Agreement”):



·the WPC Department Store Portfolio mortgage loan, which is serviced pursuant to
the BACM 2015-UBS7 pooling and servicing agreement attached hereto as Exhibit 4.2;



·the Cape May Hotels mortgage loan and the Charles River North mortgage loan,
which are serviced pursuant to the CSAIL 2015-C3 pooling and servicing agreement attached hereto as Exhibit 4.3;



·the Gulfport Premium Outlets mortgage, which is serviced pursuant to the MSBAM
2016-C29 pooling and servicing agreement attached hereto as Exhibit 4.4; and



·the Grove City Premium Outlets mortgage, which is serviced pursuant to the BACM
2016-UBS10 pooling and servicing agreement attached hereto as Exhibit 4.5.



Except as set forth below, each of the parties to each pooling and servicing agreement listed in the Exhibit
Index both (1) participates in the servicing function for purposes of Item 1122 of Regulation AB and (2) constitutes a servicer that meets the criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB for purposes of Item 1123 of Regulation
AB:



·The trustee under a pooling and servicing agreement has a nominal role with
respect to the mortgage pool securitized pursuant to such pooling and servicing agreement. The trustee’s only servicing function is the contingent obligation to make certain advances if the master servicer under such pooling and servicing agreement
fails to do so, while all other servicing functions are performed by other parties. The trustee under each of the pooling and servicing agreements listed in the Exhibit Index has confirmed to the registrant that it has not made any such contingent
advances during the reporting period, and consequently, each such trustee does not participate in the servicing function for purposes of Item 1122 of Regulation AB, nor does it perform the functions of a servicer for purposes of the definition of
“servicer” under Item 1101 of Regulation AB or for purposes of Item 1123 of Regulation AB.



·The certificate administrator under a pooling and servicing agreement performs
various payment administration functions solely for the securitization governed by such pooling and servicing agreement and the mortgage pool securitized pursuant to such pooling and servicing agreement and does not have any obligations with respect to
any other transaction. Consequently, the certificate administrator under an Outside Pooling and Servicing Agreement does not participate in the servicing function for purposes of Item 1122 of Regulation AB, nor does it perform the functions of a servicer
for purposes of the definition of “servicer” under Item 1101 of Regulation AB or for purposes of Item 1123 of Regulation AB.



·The operating advisor under a pooling and servicing agreement represents the
interests of senior certificateholders in the transaction governed by such pooling and servicing agreement and is responsible for monitoring the performance of the special servicer under such pooling and servicing agreement and producing certain reports
to certificateholders relating to the resolution of the mortgage pool securitized pursuant to such pooling and servicing agreement. The operating advisor under a pooling and servicing agreement does not have any obligations with respect to any other
transaction and is solely obligated to perform loan reporting functions with respect to the securitization governed by such pooling and servicing agreement.  Consequently, the operating advisor under an Outside Pooling and Servicing Agreement
neither participates in the servicing function for purposes of Item 1122 of Regulation AB nor performs the functions of a servicer for purposes of the definition of “servicer” under Item 1101 of Regulation AB or for purposes of Item 1123 of
Regulation AB. In addition, while the operating advisor under a pooling and servicing agreement has certain reporting obligations in respect of the related mortgage pool, it has no obligation to collect or disburse funds in respect of the mortgage pool
or to administer any of the underlying mortgage loans.  Consequently, the operating advisor under a pooling and servicing agreement participates in the servicing function for purposes of Item 1122 of Regulation AB, but is not responsible for the
“management or collection of the pool assets or making allocations or distributions to holders of the asset-backed securities” within the meaning of “servicer” under Item 1101 of Regulation AB and does not perform the functions of
a servicer for purposes of Item 1123 of Regulation AB.



·Wells Fargo Bank, National Association is the master servicer under the MSBAM
2016-C29 pooling and servicing agreement, pursuant to which the Gulfport Premium Outlets mortgage loan is serviced, and the master servicer under BACM 2016-UBS10 pooling and servicing agreement, pursuant to which the Grove City Premium Outlets mortgage
loan is serviced.  Because Wells Fargo Bank, National Association is not the MSC 2015-UBS8 master servicer, is not affiliated with any sponsor and services only the Gulfport Premium Outlets mortgage loan and the Grove City Premium Outlets mortgage
loan, which collectively constitute more than 5% but less than 10% of the mortgage pool, Wells Fargo Bank, National Association, as MSBAM 2016-C29 master servicer and BACM 2016-UBS10 master servicer, constitutes a reporting “servicing function
participant” for purposes of Item 1122 of Regulation AB, as specified in the Instruction 3 to Item 1122, but does not constitute a reporting “servicer” for purposes of Item 1123 of Regulation AB, as specified in the Instruction to Item
1123.



·LNR Partners, LLC is the special servicer under the BACM 2015-UBS7 pooling and
servicing agreement, pursuant to which the WPC Department Store Portfolio mortgage loan is serviced. Because LNR Partners, LLC is not the MSC 2015-UBS8 special servicer, is not affiliated with any sponsor and services only the WPC Department Store
Portfolio mortgage loan, which constitutes less than 5% of the mortgage pool, LNR Partners, LLC, as BACM 2015-UBS7 special servicer, does not constitute a reporting “servicing function participant” for purposes of Item 1122 of Regulation AB,
as specified in the Instruction 3 to Item 1122, and does not constitute a reporting “servicer” for purposes of Item 1123 of Regulation AB, as specified in the Instruction to Item 1123.



·U.S. Bank National Association is the custodian under the BACM 2015-UBS7 pooling and
servicing agreement, pursuant to which the WPC Department Store Portfolio mortgage loan is serviced. Because U.S. Bank National Association is not the MSC 2015-UBS8 custodian, is not affiliated with any sponsor and services only the WPC Department Store
Portfolio mortgage loan, which constitutes less than 5% of the mortgage pool, U.S. Bank National Association, as BACM 2015-UBS7 custodian, does not constitute a reporting “servicing function participant” for purposes of Item 1122 of
Regulation AB, as specified in the Instruction 3 to Item 1122, and does not constitute a reporting “servicer” for purposes of Item 1123 of Regulation AB, as specified in the Instruction to Item 1123.



·Aegon USA Realty Advisors, LLC is the special servicer with respect to the Charles River Plaza North mortgage loan (following the replacement by the related controlling note holder in 2016 of Rialto Capital
Advisors, LLC as the special servicer with respect to such mortgage loan) under the CSAIL 2015-C3 pooling and servicing agreement.  Because Aegon USA Realty Advisors, LLC is not the MSC 2015-UBS8 special servicer, is not affiliated with any sponsor
and services only the Charles River Plaza North mortgage loan, which constitutes less than 5% of the mortgage pool, Aegon USA Realty Advisors, LLC, as CSAIL 2015-C3 special servicer, does not constitute a reporting “servicing function
participant” for purposes of Item 1122 of Regulation AB, as specified in the Instruction 3 to Item 1122, and does not constitute a reporting “servicer” for purposes of Item 1123 of Regulation AB, as specified in the Instruction to Item
1123.



In addition, each of the following parties engaged the services of certain servicing function participants
and sub-servicers for the reporting period, as set forth below:



·Wells Fargo Bank, National Association, as master servicer under the MSBAM
2016-C29 pooling and servicing agreement, pursuant to which the Gulfport Premium Outlets mortgage loan is serviced, and the master servicer under the BACM 2016-UBS10 pooling and servicing agreement, pursuant to which the Grove City Premium Outlets
mortgage loan is serviced, engaged the services of (i) CoreLogic Commercial Real Estate Services, Inc. and National Tax Search, LLC, in each case as a servicing function participant in respect of the Gulfport Premium Outlets mortgage loan and the Grove
City Premium Outlets mortgage loan for the reporting period, and (ii) Midland Loan Services, a Division of PNC Bank, National Association, as a servicing function participant in respect of the Gulfport Premium Outlets mortgage loan and the Grove City
Premium Outlets mortgage loan for the reporting period.

ADDITIONAL DISCLOSURE ITEMS FOR REGULATION AB



Item 1112(b) of Regulation AB, Significant Obligor Financial Information.



Not applicable.



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



No entity or group of affiliated entities provides any enhancement or other support for the certificates as described
under Item 1114 (a) of Regulation AB.



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



No entity or group of affiliated entities provides any derivative instruments for the certificates as described under

Item 1117 of Regulation AB, Legal Proceedings.



The registrant knows of no legal proceeding pending against the sponsors, depositor, trustee, issuing entity, servicer contemplated by Item
1108(a)(3) of Regulation AB, originator contemplated by Item 1110(b) of Regulation AB, or other party contemplated by Item 1100(d)(1) of Regulation AB, or of which any property of the foregoing is the subject, that is material to security holders, other
than as disclosed in the prospectus of the issuing entity filed in a 424(b)(5) filing dated December 15, 2015, and other than as follows:



Since June 18, 2014, a group of institutional investors have filed civil complaints in the Supreme Court of the State
of New York, New York County, and later the U.S. District Court for the Southern District of New York against Wells Fargo Bank, N.A., (“Wells Fargo Bank”) in its capacity as trustee for certain residential mortgage backed securities
(“RMBS”) trusts. The complaints against Wells Fargo Bank alleged that the trustee caused losses to investors and asserted 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
included money damages in an unspecified amount, reimbursement of expenses, and equitable relief. Wells Fargo Bank has reached an agreement, in which it denies any wrongdoing, to resolve these claims on a classwide basis for the 271 RMBS trusts currently
at issue. The settlement agreement is subject to court approval. Separate lawsuits against Wells Fargo Bank making similar allegations filed by certain other institutional investors concerning 57 RMBS trusts in New York federal and state court are not
covered by the agreement. 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.



In addition to the information regarding this Item that has been disclosed in the prospectus of the issuing entity
filed in a 424(b)(5) filing dated December 15, 2015, (i) Wells Fargo Bank, National Association, the master servicer under the MSBAM 2016-C29 pooling and servicing agreement, pursuant to which the Gulfport Premium Outlets mortgage loan is serviced, and
the master servicer under the BACM 2016-UBS10 pooling and servicing agreement, pursuant to which the Grove City Premium Outlets mortgage loan is serviced, is also the MSBAM 2015-UBS8 custodian and the custodian under each Outside Pooling and Servicing
Agreement pursuant to which the outside serviced mortgage loans (other than the WPC Department Store Portfolio mortgage loan) are currently serviced; and (ii) Rialto Capital Advisors, LLC, the special servicer under the MSC 2015-UBS8 pooling and
servicing agreement, the special servicer under the MSBAM 2016-C29 pooling and servicing agreement, pursuant to which the Gulfport Premium Outlets mortgage loan is serviced, and special servicer under the BACM 2016-UBS10 pooling and servicing agreement,
pursuant to which the Grove City Premium Outlets mortgage loan is serviced, is also the special servicer for the Cape May Hotels mortgage loan, which is serviced under the CSAIL 2015-C3 pooling and servicing agreement. On November 30, 2018, Rialto
Capital Advisors, LLC (“RCA”) was acquired by investment funds managed by Stone Point Capital LLC, in partnership with the management team of RCA's affiliates.  Situs Holdings, LLC, the trust advisor under the MSBAM 2015-UBS8 pooling and
servicing agreement, is a wholly owned subsidiary of an affiliated entity of Stone Point Capital LLC.



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



The reports on assessment of compliance with the servicing criteria for asset-backed securities and the related
attestation reports on such assessments of compliance are attached hereto under Item 15.



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



Material Instance of Noncompliance



In certain instances, the Schedule AL Files (Item 1125 of Regulation AB) were not reported in accordance with
the terms specified in the transaction agreements, in conflict with Item 1122(d)(3)(i): “Reports to investors, including those to be filed with the Commission, are maintained in accordance with the transaction agreements and applicable Commission
requirements. Specifically, such reports: (A) Are prepared in accordance with timeframes and other terms set forth in the transaction agreements”.  The noncompliance consisted of omitted or inaccurately reported numbers due to the following:
(1) the initial setup files contained information at the asset level, and Midland was required to manually compile the information to present it at the loan level as required by Schedule AL; and (2) certain reporting requirements required manual
processing by Midland, including the use of various data computation formulas, quality control checks and analysis.



The identified instances did not involve the servicing of assets included in this
securitization.



Steps Taken to Remedy the Material Instance of Noncompliance



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