Item 6.02. Change of Servicer or Trustee.

Pursuant to an Assignment and Assumption Agreement, dated as of January 28, 2022, between U.S. Bank National
Association, a national banking association ("U.S. Bank N.A."), and U.S. Bank Trust Company, National
Association, a national banking association ("U.S. Bank Trust Co."), and as a result of the transfer of
substantially all of U.S. Bank N.A.'s corporate trust business to U.S. Bank Trust Co., effective as of
October 17, 2022, U.S. Bank Trust Co. succeeded U.S. Bank N.A. as trustee (in such capacity, the "Trustee")
under the pooling and servicing, dated as of March 1, 2012, among Deutsche Mortgage & Asset Receiving
Corporation, as depositor, Wells Fargo Bank, National Association, as master servicer, KeyBank National
Association as successor to CWCapital Asset Management LLC, as special servicer, U.S. Bank N.A., as
trustee, Deutsche Bank Trust Company Americas, as certificate administrator, paying agent and custodian,
and Park Bridge Lender Services LLC, as operating advisor, relating to the COMM 2012-LC4 Mortgage
Trust filed as Exhibit 4.1 to the registrant's Current Report on Form 8-K filed on
August 14, 2012 (the "Pooling and Servicing Agreement").  In connection therewith, U.S. Bank N.A.
transferred its duties, rights and liabilities with such role under the relevant transaction agreements
to U.S. Bank Trust Co.

U.S. Bank N.A. made a strategic decision to reposition its corporate trust business by transferring
substantially all of its corporate trust business to its affiliate, U.S. Bank Trust Co., a non-depository
trust company (U.S. Bank N.A. and U.S. Bank Trust Co. are collectively referred to herein as "U.S. Bank.").
Upon U.S. Bank Trust Co.'s succession to the business of U.S. Bank N.A., it became a wholly owned subsidiary
of U.S. Bank N.A.

U.S. Bancorp, with total assets exceeding $591 billion as of June 30, 2022, is the parent company of U.S.
Bank N.A., the fifth largest commercial bank in the United States.  As of June 30, 2022, U.S. Bancorp
operated over 2,200 branch offices in 26 states. A network of specialized U.S. Bancorp offices across
the nation provides a comprehensive line of banking, brokerage, insurance, investment, mortgage, trust
and payment services products to consumers, businesses, and institutions.

U.S. Bank has one of the largest corporate trust businesses in the country with office locations in
48 domestic and 2 international cities.  The Pooling and Servicing Agreement will be administered from
U.S. Bank's corporate trust office located at 190 South LaSalle Street, 7th floor, Mail code
MK-IL-SL7C, Chicago, IL 60603.

U.S. Bank has provided corporate trust services since 1924.  As of June 30, 2022, U.S. Bank was
acting as trustee with respect to over 122,000 issuances of securities with an aggregate outstanding
principal balance of over $5.5 trillion.  This portfolio includes corporate and municipal bonds,
mortgage-backed and asset-backed securities and collateralized debt obligations.

As of June 30, 2022, U.S. Bank (and its affiliate U.S. Bank Trust National Association) was acting
as trustee on 538 issuances of commercial mortgage-backed securities with an outstanding aggregate
principal balance of approximately $395,381,100,000.

U.S. Bank N.A. and other large financial institutions have been sued in their capacity as
trustee or successor trustee for certain residential mortgage-backed securities ("RMBS") trusts.
The complaints, primarily filed by investors or investor groups against U.S. Bank N.A. and
similar institutions, allege the trustees caused losses to investors as a result of alleged
failures by the sponsors, mortgage loan sellers and servicers to comply with the governing
agreements for these RMBS trusts.  Plaintiffs generally assert causes of action based upon
the trustees' purported failures to enforce repurchase obligations of mortgage loan sellers
for alleged breaches of representations and warranties, notify securityholders of purported
events of default allegedly caused by breaches of servicing standards by mortgage loan
servicers and abide by a heightened standard of care following alleged events of default.

U.S. Bank N.A. 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, that
it has meritorious defenses, and it has contested and intends to continue contesting the
plaintiffs' claims vigorously.  However, U.S. Bank N.A. 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.

On March 9, 2018, a law firm purporting to represent fifteen Delaware statutory trusts (the
"DSTs") that issued securities backed by student loans (the "Student Loans") filed a lawsuit
in the Delaware Court of Chancery against U.S. Bank N.A. in its capacities as indenture
trustee and successor special servicer, and three other institutions in their respective
transaction capacities, with respect to the DSTs and the Student Loans.  This lawsuit is
captioned The National Collegiate Student Loan Master Trust I, et al. v. U.S. Bank National
Association, et al., C.A. No. 2018-0167-JRS (Del. Ch.) (the "NCMSLT Action").  The complaint,
as amended on June 15, 2018, alleged that the DSTs have been harmed as a result of purported
misconduct or omissions by the defendants concerning administration of the trusts and special
servicing of the Student Loans.  Since the filing of the NCMSLT Action, certain Student Loan
borrowers have made assertions against U.S. Bank N.A. concerning special servicing that appear
to be based on certain allegations made on behalf of the DSTs in the NCMSLT Action.

U.S. Bank N.A. has filed a motion seeking dismissal of the operative complaint in its
entirety with prejudice pursuant to Chancery Court Rules 12(b)(1) and 12(b)(6) or, in the
alternative, a stay of the case while other prior filed disputes involving the DSTs and
the Student Loans are litigated.  On November 7, 2018, the Court ruled that the case should
be stayed in its entirety pending resolution of the first-filed cases.  On January 21, 2020,
the Court entered an order consolidating for pretrial purposes the NCMSLT Action and three
other lawsuits pending in the Delaware Court of Chancery concerning the DSTs and the Student
Loans, which remains pending.

U.S. Bank N.A. denies liability in the NCMSLT Action and believes it has performed its
obligations as indenture trustee and special servicer in good faith and in compliance in
all material respects with the terms of the agreements governing the DSTs and that it has
meritorious defenses.  It has contested and intends to continue contesting the plaintiffs'
claims vigorously.
