English Translation of Excerpts from Quarterly Securities Report Filed in Japan

This document is an English translation of selected information included in the Quarterly Securities Report for the quarter ended June 30, 2018 filed by Mitsubishi UFJ Financial Group, Inc. (“MUFG” or “we”) with the Kanto Local Financial Bureau, the Ministry of Finance of Japan, on August 14, 2018 (the “Quarterly Securities Report”). An English translation of certain information included in the Quarterly Securities Report was previously submitted in a report on Form 6-K dated August 2, 2018. Accordingly, this document should be read together with the previously submitted report.

The Quarterly Securities Report has been prepared and filed in Japan in accordance with applicable Japanese disclosure requirements as well as generally accepted accounting principles in Japan (“J-GAAP”). There are significant differences between J-GAAP and generally accepted accounting principles in the United States. In addition, the Quarterly Securities Report is intended to update prior disclosures filed by MUFG in Japan and discusses selected recent developments in the context of those prior disclosures. Accordingly, the Quarterly Securities Report may not contain all of the information that is important to you. For a more complete discussion of the background to information provided in the Quarterly Securities Report disclosure, please see our annual report on Form 20-F for the fiscal year ended March 31, 2018 and the other reports filed with or submitted to the U.S. Securities and Exchange Commission by MUFG.

Risks Relating to Our Business

We describe below some major developments and changes to update our risk factor disclosure previously included in our annual securities report for the fiscal year ended March 31, 2018 filed in Japan on June 28, 2018. The updates below are not a complete update of the prior disclosure, but instead intended to explain only the significant developments and changes that we believe may have a material impact on the risks to our business and other risks. The discussion below contains forward-looking statements, which, unless specifically described otherwise, reflect our understanding as of the date of filing of the Quarterly Securities Report. On April 1, 2018, our major subsidiary, The Bank of Tokyo-Mitsubishi UFJ, Ltd., was renamed MUFG Bank, Ltd.

The numbering of the subheading of the risk disclosure below corresponds to the numbering of the subheading of the same risk disclosure in “Risks Relating to Our Business” in our most recent annual securities report filed in Japan.

We conduct our business subject to ongoing regulations and associated compliance risks (including the effects of changes in laws, regulations, policies and voluntary codes of practice in Japan and other markets where we operate). In the current regulatory environment, we are subject to various regulatory inquiries or investigations from time to time in connection with various aspects of our business and operations. Our compliance risk management systems and programs may not be fully effective in preventing all violations of laws, regulations and rules.

Our failure to comply with all applicable laws and regulations, including those relating to money laundering, financial crimes, and other inappropriate or illegal transactions, may lead to penalties, fines, public reprimands, damage to reputation, issuance of business improvement and other administrative orders, enforced suspension of operations or, in extreme cases, withdrawal of authorization to operate. These consequences may harm our reputation resulting in loss of customer or market confidence in us or otherwise in deterioration of our business environment, and may adversely affect our business and results of operations. Our ability to obtain regulatory approvals for future strategic initiatives may also be adversely affected.

In December 2012, Bank of Tokyo-Mitsubishi UFJ agreed to make a payment to the Office of Foreign Assets Control of the U.S. Department of the Treasury, or OFAC, to settle potential civil liability for apparent violations of certain U.S. sanctions regulations from 2006 to 2007. In addition, in June 2013, Bank of Tokyo-Mitsubishi UFJ entered into a consent agreement with the New York State Department of Financial Services, or NYDFS, to resolve issues relating to certain U.S. dollar payments that were routed through New York from 2002 to 2007. Under the terms of the agreement with NYDFS, Bank of Tokyo-Mitsubishi UFJ agreed to make a civil monetary payment to NYDFS and retain an independent consultant to conduct a compliance review of the relevant controls and related matters in Bank of Tokyo-Mitsubishi UFJ’s current operations. In addition, in November 2014, Bank of Tokyo-Mitsubishi UFJ entered into a consent agreement with NYDFS to resolve issues relating to instructions given to PricewaterhouseCoopers LLP, or PwC, and the disclosures made to NYDFS in connection with Bank of Tokyo-Mitsubishi UFJ’s 2007 and 2008 voluntary investigation of Bank of Tokyo-Mitsubishi UFJ’s U.S. dollar clearing activity toward countries under U.S. economic sanctions. Bank of Tokyo-Mitsubishi UFJ had hired PwC to conduct a historical transaction review report in connection with that investigation. Under the terms of the agreement with NYDFS, Bank of Tokyo-Mitsubishi UFJ made a payment of the stipulated amount to NYDFS, and agreed to take actions on persons involved in the matter at that time, relocate its U.S. BSA/AML and OFAC sanctions compliance programs to New York, and extend, if regarded as necessary by NYDFS, the period during which an independent consultant is responsible for assessing Bank of Tokyo-Mitsubishi UFJ’s internal controls regarding compliance with applicable laws and regulations related to U.S. economic sanctions. On November 9, 2017, Bank of Tokyo-Mitsubishi UFJ entered into a Stipulation and Consent to the Issuance of a Consent Order with the U.S. Office of the Comptroller of the Currency, or OCC, under which Bank of Tokyo-Mitsubishi UFJ agreed to the entry by the OCC of a Consent Order that includes remedial terms and conditions that are substantively the same as those included in the consent agreements that Bank of Tokyo-Mitsubishi UFJ had reached with NYDFS in June 2013 and November 2014. This Consent Order, which the OCC executed, enables the OCC to supervise MUFG Bank’s plans to enhance its internal controls and compliance program relating to OFAC sanctions requirements. The Stipulation and Consent with the OCC followed MUFG’s conversion of the U.S. Branches and Agencies of MUFG Bank and Mitsubishi UFJ Trust and Banking Corporation, including MUFG Bank’s New York Branch, from state-licensed branches and agencies under the supervision of state regulatory agencies, including NYDFS, to federally licensed branches and agencies under the supervision of the OCC. MUFG Bank is undertaking necessary actions relating to these matters. In addition, MUFG Bank is currently engaged in litigation with NYDFS with regard to the conversion of its New York Branch license as well as purported violations of law alleged to have occurred prior to the federal license conversion. These developments or other similar events may result in additional regulatory actions against us or agreements to make significant settlement payments.

We have received requests and subpoenas for information from government agencies in some jurisdictions that are conducting investigations into past submissions made by panel members, including us, to the bodies that set various interbank benchmark rates as well as investigations into foreign exchange related practices of global financial institutions. We are cooperating with these investigations and have been conducting an internal investigation among other things. In connection with these matters, we and other panel members and global financial institutions have been named as defendants in a number of civil lawsuits, including putative class actions, in the United States. These developments or other similar events may expose us to significant adverse financial and other consequences.

In July 2018, Mitsubishi UFJ Morgan Stanley Securities Co., Ltd., or MUMSS, our consolidated subsidiary, received an order from the Japanese Ministry of Finance suspending the special entitlements of MUMSS as a Japanese Government Bond Market Special Participant, and also received an order from the Japanese Financial Services Agency imposing an administrative monetary penalty, each based on a finding of market manipulation relating to 10-year Japanese government bond futures.

The amounts above represent gross amounts before the deduction of allowance for credit losses.

(Litigation)

In the ordinary course of business, MUFG is subject to various litigation and regulatory matters. In accordance with applicable accounting guidance, MUFG establishes a Reserve for Contingent Losses arising from litigation and regulatory matters when they are determined to be probable in their occurrences and the probable loss amount can be reasonably estimated. Based upon current knowledge and consultation with counsel, management believes the eventual outcome of such litigation and regulatory matters, where losses are probable and the probable loss amounts can be reasonably estimated, would not have a material adverse effect on the MUFG’s financial position, results of operations or cash flows.

Management also believes the amount of loss that is reasonably possible, but not probable, from various litigation and regulatory matters is not material to MUFG’s financial position, results of operations or cash flows.

MUFG’s reporting segments are business units of MUFG which its Executive Committee, the decision-making body for the execution of its business operations, regularly reviews to make decisions regarding allocation of management resources and evaluate performance.

MUFG makes and executes unified group-wide strategies based on customer characteristics and the nature of business. Accordingly, MUFG has adopted customer-based and business-based segmentation, which consists of the following reporting segments: Retail & Commercial Banking Business Group, Japanese Corporate & Investment Banking Business Group, Global Corporate & Investment Banking Business Group, Global Commercial Banking Business Group, Asset Management & Investor Services Business Group, Global Markets Business Group and Other.

MUFG reorganized its previous business groups (Retail Banking Business Group, Corporate Banking Business Group, Global Business Group, Trust Assets Business Group and Global Markets Business Group) to realize the MUFG group’s collective strengths more effectively through integrated group-wide business operations under the medium-term business plan that was commenced in the three months ended June 30, 2018, and changed its reporting segments to the current segmentation based on the reorganized business groups.

The business segment information for the three months ended June 30, 2017 has been restated to reflect the foregoing changes in the reporting segments.

Based on a resolution of the Board of Directors on May 15, 2018, MUFG cancelled own shares on July 20, 2018 in accordance with the provisions of Article 178 of the Company Act.

On August 3, 2018, MUFG Bank, Ltd. (the “Bank”), a consolidated subsidiary of MUFG, increased its equity interest in PT Bank Danamon Indonesia, Tbk. (“Danamon”) to 40.0% by acquiring an additional 20.1% of the outstanding shares of Danamon from Asia Financial (Indonesia) Pte. Ltd. (“AFI”) and other entities (together with AFI, the “Sellers”). As a result, Danamon became an equity method affiliate of MUFG and the Bank.

The Bank intends to establish an integrated and comprehensive services platform that serves as a gateway for clients wishing to make inroads into Indonesia’s burgeoning economy as well as local companies keen on expanding into the region. This investment is also expected to strategically allow the Bank to benefit from Danamon’s foothold in the developing local retail and small and medium enterprises (SME) segments to deepen its banking franchise in Indonesia.

The Bank entered into conditional share purchase agreements with the Sellers on December 26, 2017 to acquire an aggregate equity interest of 73.8% in Danamon, subject to applicable regulatory approvals.

This strategic investment by the Bank will be executed in three steps. Upon the completion of the three steps, Danamon will be a consolidated subsidiary of MUFG and the Bank.
