The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended (“Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

This statement (this “Amendment”) amends the Statement of Beneficial Ownership on Schedule 13D, filed on October 23, 2008, as amended by the first amendment thereto, filed on October 30, 2008, the second amendment thereto, filed on May 22, 2009, the third amendment thereto, filed on June 11, 2009, the fourth amendment thereto, filed on April 1, 2010, the fifth amendment thereto, filed on May 3, 2010, the sixth amendment thereto, filed on November 9, 2010, the seventh amendment thereto, filed on April 25, 2011, the eighth amendment thereto, filed on July 1, 2011, the ninth amendment thereto, filed on October 4, 2013, the tenth amendment thereto, filed on April 7, 2016, the eleventh amendment thereto, filed on November 28, 2017 and the twelfth amendment thereto, filed on March 5, 2018 (the “Schedule 13D”), by Mitsubishi UFJ Financial Group, Inc. (“MUFG”), a joint stock company incorporated in Japan, with respect to shares of common stock (the “Common Stock”) of Morgan Stanley, a Delaware corporation (the “Company”). Capitalized terms used and not defined in this Amendment shall have the meanings set forth in the Schedule 13D. Except as specifically provided herein, this Amendment does not modify any of the information previously reported in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

In addition to the 432,017,152 shares of Common Stock held by MUFG directly, as of April 11, 2018, certain affiliates of MUFG held in the aggregate 3,067,557 shares of Common Stock (the “Managed Shares”) solely in a fiduciary capacity as the trustee of trust accounts or as the manager of investment funds, other investment vehicles and managed accounts. MUFG disclaims beneficial ownership of the Managed Shares.

Item 4: Purpose of Transaction

MUFG has entered into a sales plan (the “Plan”) with the Company and Morgan Stanley & Co. LLC (“MS & Co.”) to sell shares of Common Stock to the Company, through its agent MS & Co., as part of the Company’s share repurchase program. MUFG, the Company and MS & Co. entered into the Plan on April 18, 2018, after the Company released its quarterly financial results for the first quarter of 2018. The Plan is only intended to maintain MUFG’s ownership percentage of the Common Stock below 24.9% in order to comply with MUFG’s passivity commitments to the Board of Governors of the Federal Reserve System. MUFG’s ownership percentage increases as the outstanding number of shares of Common Stock is reduced as the Company purchases Common Stock under its share repurchase program.

Under the Plan, MUFG intends to sell Common Stock to the Company during each Quarterly Plan Period (as defined in the Plan). Such sales under the Plan may occur on any Sale Day (as defined in the Plan) during a Quarterly Plan Period, and the number of shares of Common Stock that MUFG will sell to the Company on any Sale Day is equal to a specified percentage multiplied by the number of shares the Company had previously repurchased during such period from other shareholders under its share repurchase program. The purchase price per share on each Sale Day will equal the average price per share paid by the Company for those shares it repurchased from other shareholders during such period.

The Plan may be suspended or terminated (i) by MUFG at any time for any reason by prior written notice from MUFG to the Company or (ii) by the Company by prior written notice to MUFG (a) after the end of a Quarterly Plan Period and prior to the beginning of the next Quarterly Plan Period and (b) at any time if the Company is prohibited from purchasing Common Stock by legal, contractual or regulatory restrictions applicable to it or its affiliates. The Plan is filed as Exhibit 99.20 to this Amendment and is hereby incorporated by reference herein.

Item 5. Interest in Securities of the Issuer

(a)    Rows (7) through (11) and (13) of the cover pages to this Amendment are hereby incorporated by reference. For purposes of calculating the percentages set forth on the cover pages of this Amendment, the number of shares outstanding is assumed to be 1,773,948,460 (which is the number of shares of Common Stock outstanding as of March 26, 2018, as reported by the Company in their Schedule 14A filed on April 6, 2018).

As of April 18, 2018, MUFG beneficially owns 432,017,152 shares of Common Stock.

In addition, MUFG may be deemed to be the beneficial owner of the Managed Shares. MUFG disclaims beneficial ownership of the Managed Shares.

The shares of Common Stock beneficially owned by MUFG (if MUFG is deemed to have beneficial ownership over the Managed Shares) represent approximately 24.53% of the outstanding shares of Common Stock.

(b)    Subject to the right of clients to withdraw their assets, including the Managed Shares managed by MUFG’s affiliates, MUFG has the sole power to vote or direct the vote and to dispose or to direct the disposition of shares of Common Stock beneficially owned by it as indicated in rows (7) through (11) and (13) of the cover pages to this Amendment.

(c)    Except as described herein, neither MUFG nor, to its knowledge, any of its directors or executive officers has engaged in any transactions in shares of the Company’s Common Stock in the past 60 days except transactions in a fiduciary capacity as described under Item 3.

(d)    No other person is known by MUFG to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any shares of the Company’s securities beneficially owned by MUFG, except that, if MUFG is deemed to have beneficial ownership of the Managed Shares, dividends and the proceeds from the sale of Managed Shares will be the property of the customers for whom such Managed Shares are managed.

(e)    Not applicable.

On and after the date hereof and so long as this Sales Plan has not been terminated pursuant to Paragraph F, Morgan Stanley agrees with Seller as follows:

1. During each Quarterly Plan Period, Morgan Stanley will (i) notify Seller in writing promptly if, based on its internal monthly share count worksheets, the aggregate number of Shares that Morgan Stanley has repurchased under its share repurchase program has caused Seller’s percentage of ownership of the Shares to be 24.5% or greater and (ii) use commercially reasonable efforts to cooperate with Seller to implement measures to reduce Seller’s percentage of ownership of the Shares to less than 24.5%, including designating one or more Business Days during the relevant Quarterly Plan Period as Sale Days.

1. Subject to Paragraph F, on each Sale Day, Seller agrees to sell and Morgan Stanley agrees to purchase, through its agent MS & Co., a number of Shares equal to the Number of Shares for such Sale Day (each such sale, a “Sale”) unless Morgan Stanley determines after consultation with qualified outside counsel that it would be illegal for Morgan Stanley to do so.

2. On the Settlement Date for each Sale, (i) Seller shall authorize MS & Co. to transfer a number of Deposited Shares equal to such Number of Shares to an account of Morgan Stanley, and (ii) MS & Co., as an agent of Morgan Stanley, shall make a payment in immediately available funds to the account designated by Seller pursuant to Paragraph G.3 below in an amount equal to the product of (x) the Number of Shares for the Sale Day for such Sale and (y) the Sale Price for such Sale.

5. The parties hereto agree that, absent any change in applicable law, the Sales of Shares pursuant to this Sales Plan shall be treated for U.S. federal income tax purposes as distributions governed by Section 301 of the Internal Revenue Code of 1986, as amended. The MS Entities shall be entitled to deduct and withhold from any amount payable to Seller pursuant to this Sales Plan such amounts as either MS Entity is required to deduct and withhold with respect to the making of such payment under any provision of U.S. federal, state, local or non-U.S. law, and taking into account the relevant provisions of any applicable income tax treaty as reflected on any duly completed IRS Form W-8BEN-E (or applicable successor form or any similar form prepared and provided under state, local or non-U.S. law) provided by Seller to the MS Entities. If any amount is so withheld, such amounts shall be treated for all purposes of this Sales Plan as having been paid to Seller.

This Sales Plan may not be suspended or terminated except in accordance with Paragraphs F.1 and F.2 below.

1. This Sales Plan may be suspended or terminated by Seller at any time for any reason by prior written notice from Seller sent to MS & Co’s compliance office by e-mail, facsimile or overnight mail at the address or fax number set forth in Paragraph G.3 below and received by MS & Co’s compliance office at least one Business Day prior to the Business Day on which this Sales Plan is to be suspended or terminated; provided, however, that Seller’s suspension or termination of this Sales Plan shall not relieve it from its obligation to settle any then pending Sale transaction. If such notice is made with respect to a suspension, rather than a termination, it shall indicate the anticipated duration of the restriction. The Sales by Seller of the Shares to Morgan Stanley shall resume under this Sales Plan promptly after receipt of notice from Seller that Sales may resume.

2. This Sales Plan may be suspended or terminated by Morgan Stanley (i) after the end of a Quarterly Plan Period and prior to the beginning of the next Quarterly Plan Period or (ii) at any time if Morgan Stanley has determined after consultation with qualified outside counsel that it is prohibited from purchasing the Shares by a legal, contractual or regulatory restriction applicable to it or its affiliates (including any such restriction relating to its possession of material nonpublic information about Morgan Stanley or the Shares). In either such case Morgan Stanley shall deliver a written notice to Seller by e-mail, facsimile or overnight mail at the address or fax number set forth in Paragraph G.3 below at least one Business Day prior to the Business Day on which this Sales Plan is to be suspended or terminated; provided, however, that Morgan Stanley’ suspension or termination of this Sales Plan shall not relieve it from its obligation to settle any then pending Sale transaction. If such notice is made with respect to a suspension, rather than a termination, it shall indicate the anticipated duration of the restriction.

1. The parties hereto acknowledge and agree that this Sales Plan is a “securities contract,” as such term is defined in Section 741(7) of Title 11 of the United States Code (the “Bankruptcy Code”), entitled to all the protections given to such contracts under the Bankruptcy Code.

2. This Sales Plan may be amended by Seller only upon the written consent of Morgan Stanley.

3. (a) All notices to the MS Entities under this Sales Plan shall be given to MS & Co. by e-mail, facsimile or overnight mail as specified below:

Seller agrees to notify MS & Co. in writing of any changes to the contact information provided.

[                ]

In addition, all other notices to Seller under this Sales Plan shall be given to Seller by e-mail, facsimile or overnight mail as specified below:

[                ]

    (c) Seller designates the following account for payments to Seller by MS & Co., as an agent of Morgan Stanley, pursuant to Paragraph E.2, which designation Seller may change at any time for any reason by notifying MS & Co. in writing:

[                ]

4. Seller’s rights and obligations under this Sales Plan may not be assigned or delegated without the written permission of Morgan Stanley, and any MS Entity’s rights and obligations under this Sales Plan may not be assigned or delegated without the written permission of Seller. Any attempted or purported assignment or delegation in violation hereof shall be null and void.

5. This Sales Plan may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

6. If any provision of this Sales Plan is or becomes inconsistent with any applicable law, rule or regulation, that provision will be deemed modified or, if necessary, rescinded in order to comply with the relevant law, rule or regulation. All other provisions of this Sales Plan will continue and remain in full force and effect. This Sales Plan shall be interpreted to comply with requirements of Rule 10b5-1(c) under the Exchange Act.
