Item 6.0204 ~~Change~~Failure to make a Required Distribution. The Certificate Administrator made distributions to the Certificateholders on the December 12, 2022 Distribution Date. The Certificate Administrator was notified on December 14, 2022 of ~~Servicer~~a orpayment ~~Trustee~~revision to the Class D and Class E Certificateholders. The payment revisions were made to reflect the payoff of a Mortgage Loan, and resulted in additional principal payments to the Class D Certificateholders in the amount of $9,979,212.49 and additional principal payments to the Class E Certificateholders in the amount of $46,008.85. The additional payments were made to the Class D and Class E Certificateholders on December 16, 2022.

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”) and as certificate administrator/paying agent (in such capacity, the “Certificate Administrator”) under the pooling and servicing, dated as of December 1, 2012, among UBS Commercial Mortgage Securitization Corp., as depositor, Wells Fargo Bank, National Association, as master servicer, Rialto Capital Advisors, LLC, as special servicer, Trimont Real Estate Advisors, Inc., as operating advisor, and U.S. Bank N.A., as trustee, certificate administrator, paying agent and custodian, relating to the UBS-Barclays Commercial Mortgage Trust 2012-C4 filed as Exhibit 4 to the registrant’s Current Report on Form 8-K filed on December 20, 2012 (the “Pooling and Servicing Agreement”). In connection therewith, U.S. Bank N.A. transferred its duties, rights and liabilities with such roles under the relevant transaction agreements to U.S. Bank Trust Co. U.S. Bank N.A. will continue to act as custodian (in such capacity, the “Custodian”) under the Pooling and Servicing Agreement.

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. The Trustee will maintain the accounts of the issuing entity in the name of the Trustee at 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, and its office for certificate transfer purposes is at 111 Fillmore Avenue, St. Paul, Minnesota 55107, Attention: Bondholder Services.

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.

The Certificate Administrator shall make each monthly statement available to the holders via the trustee’s internet website at https://pivot.usbank.com. Holders with questions may direct them to the trustee’s bondholder services group at (800) 934-6802.

As of June 30, 2022, U.S. Bank (and its affiliate U.S. Bank Trust National Association) was acting as trustee, registrar and securities administrator on 364 issuances of commercial mortgage-backed securities with an outstanding aggregate principal balance of approximately $324,376,900,000.

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.

Under the terms of the Pooling and Servicing Agreement, U.S. Bank Trust Co. is responsible for securities administration, which includes pool performance calculations, distribution calculations and the preparation of monthly distribution reports. The distribution reports will be reviewed by an analyst and then by a supervisor using a transaction-specific review spreadsheet. Any corrections identified by the supervisor will be corrected by the analyst and reviewed by the supervisor. The supervisor also will be responsible for the timely delivery of reports to the administration unit for processing all cashflow items. As securities administrator, U.S. Bank Trust Co. is also responsible for the preparation and filing of all REMIC tax returns on behalf of the issuing entity and the preparation of monthly reports on Form 10-D, certain current reports on Form 8-K and annual reports on Form 10-K that are required to be filed with the Securities and Exchange Commission on behalf of the issuing entity. In the past three years, the securities administrator has not made material changes to the policies and procedures of its securities administration services for commercial mortgage-backed securities.

U.S. Bank N.A. will act as Custodian of the mortgage files pursuant to the Pooling and Servicing Agreement. As Custodian, U.S. Bank N.A. is responsible for holding the mortgage files on behalf of the Trustee. U.S. Bank N.A. will hold the Loan Documents in a custodial vault located in 1133 Rankin Street, Suite 100, St. Paul, MN 55116. The mortgage files are tracked electronically to identify that they are held by the Custodian pursuant to the Pooling and Servicing Agreement. U.S. Bank N.A. uses a barcode tracking system to track the location of, and owner or secured party with respect to, each file that it holds as Custodian, including the mortgage files held as on behalf of the Trustee. As of June 30, 2022, U.S. Bank held approximately 12,681,000 document files for approximately 980 entities and has been acting as a custodian for over 35 years.
