NOTES TO FINANCIAL STATEMENTS

AT DECEMBER 31, 2018 AND 2017, AND FOR THE YEAR ENDED DECEMBER 31, 2018

The following summary of the Morgan Stanley 401(k) Plan (the “Plan”) is provided for general information purposes only. Participants should refer to the Plan document for more complete information. Terms used in this description have the same meaning as in the Plan document.

General  — The Plan is a profit-sharing plan that includes a “qualified cash or deferred arrangement” as described in Section 401(k) of the Internal Revenue Code of 1986, as amended (the “Code”), and is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). The Plan’s interest in the Morgan Stanley Stock Fund is designated as an employee stock ownership plan within the meaning of Code section 4975(e)(7) to the extent provided in the Plan.

Morgan Stanley Domestic Holdings, Inc. (the “Plan Sponsor”) is a corporation wholly owned by Morgan Stanley Capital Management, LLC, a limited liability company whose sole member is Morgan Stanley (the “Company”). As of December 31, 2018, Morgan Stanley Services Group Inc. (“MSSG”) was a corporation wholly owned by Morgan Stanley Services Holdings LLC, a limited liability company whose sole member was the Plan Sponsor (see Note 7). The Plan Sponsor has delegated certain functions to MSSG. The Company’s Chief Human Resources Officer or his or her delegate (the “Plan Administrator”) has the authority to control and manage the operation and administration of the Plan, make rules and regulations and take actions to administer the Plan. The Plan Administrator has delegated certain operational and administrative responsibilities to certain employees in the Company’s Human Resources department.

All of the Plan’s investments are held in a trust account (“trust account”) at The Northern Trust Company, N.A. (the “Trustee”).

Eligibility  — U.S. benefits-eligible employees, generally defined as full-time and part-time (regularly scheduled to work at least 50% of the Company’s standard work week) employees of participating companies are eligible to participate in the Plan upon hire.

Part-time employees who are regularly scheduled to work less than 50% of the Company’s standard work week may elect to commence participation in the Plan on the later of (A) the date their employment commences or (B) January 1, 2018, without regard to age.

Eligible participants who terminate employment and are later rehired by a participating company may participate in the Plan immediately upon rehire. Individuals who are (a) classified by a participating company as non-U.S. benefits-eligible workers, interns, summer associates, contingent workers, leased workers, independent contractors or consultants, regardless of whether or not such classification is subsequently upheld for any purpose by a court or federal, state or local administrative authority; (b) covered by a collective bargaining agreement with respect to which a participating company is a party, unless such agreement provides for participation in the Plan; (c) first hired or transferred to a participating company while in an hourly status on or after July 1, 2004; or (d) Puerto Rico residents, are not eligible to participate in the Plan.

Employee Contributions  — Eligible participants may elect to contribute before-tax or Roth after-tax contributions of 1% to 30% of eligible pay subject to Code limits ($18,500 for 2018). Those participants who have attained at least age 50 by the end of the year may elect an additional before-tax or Roth after-tax “Catch-Up Contribution” of 1% to 30% of eligible pay, subject to Code limits ($6,000 for 2018).

Certain eligible participants may also elect to contribute non-Roth after-tax contributions of 1% to 30% of eligible earnings. Participants eligible to make non-Roth after-tax contributions include eligible employees considered to be non-highly compensated employees (for 2018, employees who earned less than $305,000 during 2017). Participants may also contribute amounts representing eligible rollover distributions from other qualified retirement plans, excluding other qualified plans sponsored by the Company and its affiliates. All contributions are subject to certain Code limitations.

The Plan was amended effective January 17, 2018 to exclude from the definition of eligible pay a special one-time bonus payment (generally not to exceed $1,000) made to certain employees in the first calendar quarter of 2018.

Company Contributions  — In addition to the eligibility requirements for each type of Company Contribution described below, to be eligible for Company Contributions for any given Plan Year, a participant must be actively at work or on an authorized leave of absence on December 31 or, during the year, have terminated employment because of retirement or Release, become totally and permanently disabled or died. Company Contributions are generally credited to participant accounts during the first quarter of the year following the calendar year for which the contribution amounts are determined.

Company Match : The Plan-provided Company Match for 2018 was one dollar for each dollar of before-tax or Roth after-tax contributions that eligible participants contributed to the Plan, up to a maximum of 4% of eligible pay, up to the Code limit of $275,000. The maximum Company Match for 2018 was limited to $11,000. The Company Match is made at the discretion of the Plan Sponsor.

The 2018 Company Match contributions were invested according to each participant’s investment elections on file or in a default fund or funds, as selected by the Plan Administrator. The 2018 Company Match was $234,156,585, of which $6,783,579 was covered by forfeitures held by the trust account. The contribution was recorded as Employer contributions receivable at December 31, 2018 and paid in cash by the Company to the Plan in January 2019. The 2017 Company Match was $218,502,369 of which $6,052,392 was covered by forfeitures held by the trust account. The contribution was recorded as Employer contributions receivable at December 31, 2017 and paid in cash by the Company to the Plan in January 2018.

Fixed Contribution : Eligible employees with annualized base pay and eligible annual pay of $100,000 or less and who are not employed as Financial Advisors, Producing Assistant Branch Managers, Producing Branch Managers, or Producing Sales Managers (or equivalent title), Advisory Directors or Senior Advisors (or equivalent title) at December 31 and who are not Saxon employees of Morgan Stanley’s U.S. Residential Mortgage Business receive a Fixed Contribution of 2% of eligible pay regardless of whether they contribute to the Plan or receive a Company Match. The 2018 Fixed Contribution of $17,412,777 was recorded as Employer contributions receivable at December 31, 2018 and paid in cash by the Company in January 2019. The 2017 Fixed Contribution of $17,656,210 was recorded as Employer contributions receivable at December 31, 2017 and paid in cash by the Company in January 2018.

Citi Pension Transition Contributions : To be eligible for Citi Pension Transition Contributions, employees who transferred from Citigroup to the Company or its affiliates in connection with the formation of the Company’s Wealth Management business segment must have been notified by

Citigroup that their prior plan benefit opportunity qualified them for transition contributions under the Citigroup 401(k) Plan and they must have been at least age 45 with five or more years of service, including prior Citigroup service, at December 31, 2010. Citi Pension Transition Contributions may be available for up to 10 Plan Years, beginning with the 2011 Plan year, as determined by the Plan Sponsor, in its discretion.

The Citi Pension Transition Contributions are based on the one-time calculation Citigroup performed to determine the percentage of annual eligible pay for the annual transition contributions under the Citigroup 401(k) Plan. The 2018 Citi Pension Transition Contribution of $2,185,280 was recorded as Employer contributions receivable at December 31, 2018 and paid in cash by the Company in January 2019. The 2017 Citi Pension Transition Contribution of $2,216,371 was recorded as Employer contributions receivable at December 31, 2017 and paid in cash by the Company in January 2018.

Morgan Stanley Transition Contribution : Eligible employees are those who earned a Morgan Stanley pension benefit or received a 401(k) Plan Retirement Contribution during 2010 and at December 31, 2010 were employed by a participating company and at least age 45 with five or more years of service. Eligible employees receive a Morgan Stanley Transition Contribution regardless of whether or not they contribute to the Plan. Morgan Stanley Transition Contributions may be available under the Plan for up to 10 Plan Years as determined by the Plan Sponsor in its discretion, beginning with the 2011 Plan Year.

The Morgan Stanley Transition Contribution is based on a formula generally intended to provide 80% of (1) minus (2):

1. Under the Plan provisions in effect in 2010:

The estimated value of the benefit the employee would have earned under the Morgan Stanley Employees Retirement Plan (or what the employee would have received as a Retirement Contribution in the Plan), plus

The Company Match the employee would have received had the employee contributed 6% of eligible pay to the Plan (regardless of how much the employee actually contributed).

2. Under the Plan provisions in effect during the applicable Plan year:

The maximum Company Match available under the Plan (regardless of how much the employee actually contributed), plus

The employee’s Fixed Contribution for the Plan year, if applicable.

The 2018 Morgan Stanley Transition Contribution of $24,595,648 was recorded as Employer contributions receivable at December 31, 2018 and paid in cash by the Company in January 2019. The 2017 Morgan Stanley Transition Contribution of $25,601,028 was recorded as Employer contributions receivable at December 31, 2017 and paid in cash by the Company in January 2018.

Participant Accounts  — Individual accounts are maintained for each Plan participant. Each participant’s account is credited with the participant’s contributions, allocations of Company Contributions and Plan earnings, and charged with an allocation of Plan losses and administrative expenses not otherwise paid by the Plan Sponsor, and reduced by the amount of any benefit payments to such participant. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Investments  — Participants direct the investment of their contributions into various investment options offered by the Plan, which are subject to change from time to time. At December 31, 2018, the Plan offered six mutual funds, 20 commingled or collective trust funds, one employer stock fund, and 13 separately managed accounts.

The Plan is intended to meet the requirements of Section 404(c) of ERISA, with the result that participants, and no other fiduciaries, are responsible for the investment of their Plan accounts.

Employer Stock Provisions — The Morgan Stanley Stock Fund is invested primarily in “employer securities” (as defined in the Code), is designated an employee stock ownership plan to the extent provided in the Plan, and is subject to additional plan provisions, including the ability of eligible participants to elect to receive current cash dividend distributions relating to the Morgan Stanley Stock Fund.

Voting and Tender Rights  — Each participant may direct a vote on shares of Company common stock in the Morgan Stanley Stock Fund that are allocated to his or her Plan account. Each participant is to be notified prior to the time that voting rights are to be exercised. Unvoted shares, including shares held in the Plan’s forfeiture account, are to be voted in the same proportion as the total actual votes cast by participants with respect to shares held in the Morgan Stanley Stock Fund for or against the matter under consideration. Similar rules apply to tender or other similar rights appurtenant to Company common stock held in the Morgan Stanley Stock Fund, except that shares for which no tender direction is given by the participant will not be tendered. If there is a tender for less than all shares or if there are more tender directions than can be satisfied, participant shares are to be tendered on a pro rata basis.

Vesting  — Participants are vested immediately in their Employee Contributions plus earnings thereon. Generally, participants are vested in any Company Contributions upon the earlier of: (i) completion of three years of service, or (ii) termination of employment due to death, retirement, Release or Total and Permanent Disability, each as defined by the Plan. There is no partial vesting. A participant is always fully vested in dividends paid with respect to the Morgan Stanley Stock Fund.

Other — Certain reservists and persons who provide military service are entitled to additional rights under the Plan. Additional rules apply in the event that the Plan becomes top-heavy as described in the Code.

Forfeitures   — Forfeitures are used to reduce the year-end Company Contributions and pay certain Plan expenses.

Notes Receivable from Participants  — Generally, a participant may borrow up to the lesser of $50,000 or 50% of his/her vested Plan account. The loan is secured by the balance in the participant’s account and bears interest at a rate determined by the Plan Administrator. Fixed, Retirement and Transition Contributions, each as defined by the Plan, are not eligible for loans. Each loan processed incurs a $75 administrative fee. Generally, principal and interest are paid ratably through payroll deductions back to the individual participant’s account; participants may fully or partially pre-pay their loans without penalty. A participant may only have one outstanding loan at a time. Loans become due on termination of employment, except in the case of Release, in which case a participant may continue repayments for up to 12 months.

Domestic Relations Orders — Generally, participants who submit a domestic relations order for qualification incur a $750 qualification fee which is paid from the participant’s and alternate payee’s accounts.

Payment of Benefits  — Participants may elect to receive all or a portion of their vested account balance following termination of employment.

Participants may withdraw any vested amount allocated to their accounts while in service after attaining age 59-1/2. In the event of a hardship (as defined in the Plan), participants regardless of age may withdraw their vested Employee and Company Contributions to the extent permitted by the Plan. Voluntary Employee Contributions made before 1984 and after-tax Employee Contributions made after 1983 also may be withdrawn in service without regard to the participant’s age, subject to Plan terms. Payments are made in cash and/or in-kind in shares of Morgan Stanley stock at the direction of the participant. Non-hardship withdrawals are limited to eight per year.

A participant may elect to receive his or her vested interest in the Morgan Stanley Stock Fund in-kind. Shares are recorded electronically in book entry form on the records of the Company’s transfer agent, Broadridge Financial Solutions, Inc. The Company’s transfer agent prior to September 8, 2017 was Computershare.

Plan Termination  — Although it has not expressed any intent to do so, the Plan Sponsor (or its delegate, MSSG) has the right under the Plan to terminate the Plan subject to the provisions of ERISA. In such event, participants become fully vested in any Company Contributions to the extent required by the Code.

Basis of Accounting  — The Plan’s financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America.

Use of Estimates  — The preparation of financial statements requires Plan management to make estimates and assumptions regarding the valuation of certain financial instruments that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from the estimates and assumptions used.

Administrative Expenses  — Administrative expenses of the Plan are paid by the Plan, unless paid by the Plan Sponsor, as provided in the Plan document. The Plan Sponsor is under no obligation to pay the Plan’s administrative expenses.

Payment of Benefits  — Benefit payments to participants are recorded upon distribution. Amounts allocated to participants who elected to withdraw from the Plan during the years ended December 31, 2018 and 2017 generally were paid prior to the respective year end. Amounts requested in the plan year but paid subsequent to the plan year were not significant.

Risks and Uncertainties  — The Plan utilizes various investment options, including derivative instruments. Investments, in general, are exposed to various risks, such as interest rate, market liquidity and credit risks, as well as overall market volatility. Due to the level of risk associated with certain investments and the sensitivity of certain fair value estimates to changes in valuation assumptions, it is reasonably possible that changes in value of investments will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the financial statements.

Investment Valuation and Income Recognition  — Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on an accrual basis. The cost of Plan investments is based on the average cost method for individual securities. Dividends are recorded on the ex-dividend date.

Realized and unrealized gains and losses on the investments are reflected in Net investment income (loss)—Net appreciation (depreciation) in fair value of investments, and include the Plan’s gains and losses on investments bought and sold as well as held during the year. Management fees and operating expenses charged to each of the investment options under the Plan are deducted from income earned and are not separately reflected in the Statement of changes in net assets available for benefits. Consequently, management fees and operating expenses are reflected as a reduction of investment return for such investments.

The Plan’s investments and derivative instruments are measured at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date (see Note 6).

In determining fair value, the Plan uses various valuation approaches. A hierarchy for inputs is used in measuring fair value that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three levels wherein Level 1 represents quoted prices in active markets, Level 2 represents valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, and Level 3 consists of valuation techniques that incorporate significant unobservable inputs and, therefore, require the greatest use of judgment.

The availability of observable inputs can vary from product to product and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new and not yet established in the marketplace, the liquidity of markets and other characteristics particular to the product. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Plan in determining fair value is greatest for instruments categorized in Level 3 of the fair value hierarchy.

The Plan considers prices and inputs that are current at the measurement date, including during periods of market dislocation. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or Level 2 to Level 3 of the fair value hierarchy.

In certain cases, the inputs used to measure fair value may fall into different Levels of the fair value hierarchy. In such cases, for disclosure purposes, the Level of the fair value hierarchy within which the fair value measurement falls in its entirety is determined based on the lowest Level input that is significant to the fair value measurement in its entirety.

For assets and liabilities that are transferred between Levels in the fair value hierarchy during the period, fair values are ascribed as if the assets or liabilities had been transferred at the beginning of the period.

Notes Receivable from Participants  — Notes receivable from participants are measured at their unpaid principal balance. Interest is repaid monthly and any delinquent interest payments at December 31, 2018 and 2017 were not significant. Based on the terms of the Plan document, delinquent participant loans are recorded as distributions when a distributable event occurs.

Derivative instruments are permitted in the Plan’s separately managed account (“Separate Account”) portfolios only to the extent that they comply with all of the Plan’s policy guidelines, and are consistent

with the Plan’s risk and return objectives. In addition, derivative instruments may be used only if they are deemed to be more attractive than a similar direct investment in the underlying cash market, or if the investment vehicle is being used to manage the risk of the portfolio. Any use of derivative instruments may not result in exposure of the Plan to investment sectors that are otherwise prohibited under the investment guidelines.

The investment guidelines established with each Separate Account manager for the Plan set forth the guidelines for the commitments that an investment manager may make with respect to derivative instruments. Within the scope of the investment guidelines, the Plan may be invested in futures, options, swaps and forwards.

Market risk arises from adverse changes in the fair value of these contracts.

Futures and Options — The trust account held certain futures contracts on Eurodollars in separately managed accounts at December 31, 2018 within the PIMCO Core Fixed Income Fund, PIMCO Real Return Portfolio Fund, PIMCO Low Duration Fund and Morgan Stanley International Equity Fund and at December 31, 2017 within the PIMCO Core Fixed Income Fund, PIMCO Real Return Portfolio Fund and PIMCO Low Duration Fund. Both written and purchased options were held as underlying investments. When the investment manager purchases or writes an option, an amount equal to the premium paid or received by the Plan is recorded as an asset or liability and is subsequently adjusted to the current market value of the option written or purchased. The fair value of these investments at December 31, 2018 and 2017 was not significant and the changes in fair value are accounted for as part of Net appreciation (depreciation) in fair value of investments in the Statement of changes in net assets available for benefits.

Swaps  — Under the investment managers’ standard International Swap and Derivatives Association agreements, counterparty risk is limited by provisions which allow for the mutual exchange of collateral should a swap’s market value exceed $250,000. Further, the investment managers are instructed to restrict trading to only those counterparties with the largest capitalization and highest credit ratings in the industry. Investment manager policy is to execute swaps only with counterparties whose credit rating is A-/A3 or better, unless otherwise approved by the Plan. At December 31, 2018 and 2017, the investment assets held by the Plan included positions in several interest rate swaps, where fixed rates were paid to counterparties in exchange for floating rates, and credit default swaps. At December 31, 2018, the investment assets held by the Plan also included positions in total return swaps. These assets were held in Separate Accounts at December 31, 2018 within the PIMCO Core Fixed Income Fund, PIMCO Real Return Portfolio Fund, PIMCO Low Duration Fund and Morgan Stanley International Equity Fund and at December 31, 2017 within the PIMCO Core Fixed Income Fund, PIMCO Real Return Portfolio Fund, and PIMCO Low Duration Fund. The Plan also held in Separate Accounts several positions in inflation swaps at December 31, 2018 and 2017 within the PIMCO Real Return Portfolio Fund. The fair value of these investments at December 31, 2018 and 2017 was not significant and the changes in fair value are accounted for as part of Net appreciation (depreciation) in fair value of investments in the Statement of changes in net assets available for benefits.

Forwards  — The Plan may enter into forward foreign currency contracts in order to hedge certain foreign currency denominated investments. Forward foreign currency commitments are generally entered into with counterparties of high credit quality; therefore, the risk of nonperformance by the counterparties is considered negligible. Additionally, the Plan’s investment guidelines require that the forward foreign currency contracts be restricted in their application and used for economic hedging purposes. The Plan held positions in forward foreign currency contracts in Separate Accounts at December 31, 2018 in the PIMCO Real Return Portfolio Fund, Fidelity Institutional Asset Management Select International Small Growth Fund, Artisan International Growth Fund, PIMCO Low Duration

Fund, and Morgan Stanley International Equity Fund and at December 31, 2017 in the PIMCO Real Return Portfolio Fund, Fidelity Institutional Asset Management Select International Small Growth Fund, Artisan International Growth Fund and PIMCO Low Duration Fund. The Plan also held positions in forward equity contracts in Separate Accounts at December 31, 2018 in the Morgan Stanley International Equity Fund. The fair value of these investments at December 31, 2018 and 2017 was not significant and the changes in fair value are accounted for as part of Net appreciation (depreciation) in fair value of investments in the Statement of changes in net assets available for benefits.

Securities sold under agreements to repurchase (“repurchase agreements”) — The investment managers, BlackRock and PIMCO, entered into several repurchase agreements. The fair value of these investments at December 31, 2018 and 2017 was not significant and the changes in fair value are accounted for as part of Net appreciation (depreciation) in fair value of investments in the Statement of changes in net assets available for benefits.

There were 40 and 37 investment options, respectively, available in the Plan at December 31, 2018 and 2017, of which three and four, respectively, were managed by Morgan Stanley Investment Management, 36 and 32, respectively, were managed by third parties and one of which was an employer stock fund (the Morgan Stanley Stock Fund). All party-in-interest investment options are in the Morgan Stanley Stock Fund, Northern Trust Short-Term Investment Fund, the funds managed by Morgan Stanley Investment Management, an affiliate of the Plan Sponsor, and funds issued by PIMCO, Blackrock, Voya Financial Inc., AQR Capital Management, T. Rowe Price, William Blair, Rice Hall James, Artisan Partners, Fidelity Institutional Asset Management, Shenkman, and Thompson, Siegel & Walmsley.

At December 31, 2018 and 2017, the Plan held 37,084,930 shares and 37,851,013 shares, respectively, of Morgan Stanley common stock with a fair value of $1,470,417,474 and $1,986,042,651 respectively, and had net realized gains of $49,957,987 during 2018. The Plan earned dividend income of $40,998,018 on Morgan Stanley common stock for the year ended December 31, 2018. Eligible participants have the opportunity to elect to receive current cash payment of the dividends paid on the Morgan Stanley Stock Fund held within the Plan to the extent provided in the Plan.

At December 31, 2018 and 2017, the Plan held 195,000 shares and 235,300 shares, respectively, of Mitsubishi UFJ Financial Group common stock with a fair value of $956,027 and $1,726,160, respectively.

At December 31, 2018 and 2017, the Plan held investments in Registered Investment Companies issued by Morgan Stanley Investment Management with a fair value of $1,312,018,722 and $1,807,712,968 respectively, and had a net realized gain of $126,380,868 and generated dividend and interest income of $5,983,809 during 2018. At December 31, 2018, the Plan also held investments in a Collective Trust Fund issued by Morgan Stanley Investment Management with a fair value of $137,126,130.

Certain officers and employees of the Plan Sponsor (who may also be participants in the Plan) perform administrative services related to the operation, record keeping and financial reporting of the Plan. The Plan Sponsor pays these salaries and other administrative expenses on behalf of the Plan. Certain fees, including fees for the investment management services, to the extent not paid by the Plan Sponsor, are paid by the Plan. All direct and indirect fees paid by the Plan are considered party-in-interest transactions.

At December 31, 2018 and 2017, the Plan held notes receivable from participants for participant loans of $103,826,360 and $101,010,373, respectively, which are considered party-in-interest transactions.

The Internal Revenue Service determined and informed the Plan Sponsor by a letter dated May 22, 2018, that the Plan and its related trust account continue to be designed in accordance with the applicable provisions of the Code. The Plan has been amended since receiving this letter, however, the Plan Sponsor and the Plan Administrator believe the Plan is currently designed and operated in compliance with the applicable requirements of the Code.

The Plan Sponsor has analyzed the tax positions taken by the Plan, and has concluded that at December 31, 2018 and 2017, there are no uncertain tax positions taken by the Plan that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits of the Plan for any tax periods in progress. The Plan Sponsor believes the Plan is no longer subject to income tax examinations for years prior to 2013.

The following descriptions of the valuation methods and assumptions used by the Plan to determine the fair values of investments apply to investments held directly by the Plan.

Registered Investment Companies (“RIC’s”) – Mutual funds are registered with the Securities and Exchange Commission (“SEC”) and are intended to meet the requirements of the Investment Company Act of 1940 with respect to income distribution, fee structure, and diversification of assets. Mutual funds are generally marked to quoted prices or net asset value (“NAV”) and are categorized in Level 1 of the fair value hierarchy if based upon prices which are observable in an active market. The PIMCO International Bond (Unhedged) fund requires the Trustee to calculate the fair value since the fund has a daily interest rate factor that pays a monthly dividend and therefore the fund is categorized as Level 2 of the fair value hierarchy. The Plan generally prohibits the sale of these investment options within 30 days of a purchase into that investment option.

Separately Managed Accounts – The Plan holds investments in the Morgan Stanley Stock Fund (the “Fund”) holding Morgan Stanley common stock and containing a short-term investment fund to facilitate participant transactions into and out of the Fund. There are no unfunded commitments and no restricted redemption notice periods. The Company has specific rules that govern employee transactions in Morgan Stanley stock. Employees may transact in Morgan Stanley stock (including the Fund) only during a window period. Shorter window periods and prior approval requirements apply to those employees deemed Access Persons (as defined in the Company’s employee trading policy) by the Company. Access Persons who are members of the Company’s Management or Operating Committees are prohibited from selling the Fund within six months of a purchase.

The remaining Separate Accounts are professionally managed portfolios held by the Plan. The participants share in the appreciation and depreciation in proportion to their contribution to the Separate Account. Separate Accounts are administered and supervised by investment managers who decide how to invest funds contributed by investors, subject to written investment guidelines. At December 31, 2018 and 2017, the Plan’s Separate Accounts consisted of the T. Rowe Price U.S. Large-Cap Value Fund, the PIMCO Core Fixed Income Fund, the PIMCO Real Return Fund, the PIMCO Low Duration Fund, the Shenkman Capital High Yield Bond Fund, the Fidelity Institutional Asset Management Select International Small Cap Fund, the Artisan International Growth Fund, the BlackRock Government Short Term Investment Fund, the Thompson, Siegel & Walmsley Mid Cap Value Fund, the William Blair Small Cap Value Fund, the Voya Mid Cap Growth Fund, and the Rice Hall James Small Cap Opportunities Fund. At December 31, 2018, the Plan’s Separate Accounts also consisted of AQR

International Equity Fund. The Trustee is responsible for determining the Separate Accounts’ fair value. Terms of the agreements with the investment managers (“Investment Management Agreements”) for the Separate Accounts permit the termination of the Investment Management Agreements and the distribution of the Separate Accounts’ securities at fair value. There were no unfunded commitments and no restricted redemption notice periods. The Plan generally prohibits the sale of these investment options within 30 days of a purchase into that investment option.

A description of the valuation methods and assumptions applied to the major categories of the Fund and the Separate Accounts are as follows:

Corporate equities

Corporate equities, including Morgan Stanley common stock, are exchange-traded equity securities that are generally valued based on quoted prices from the exchange. To the extent these securities are actively traded, valuation adjustments are not applied. Corporate equities are categorized in Level 1 of the fair value hierarchy. Stapled securities, consisting of two or more corporate equity securities that are contractually bound to form a single salable unit that cannot be bought or sold separately, are categorized in Level 2 of the fair value hierarchy.

Cash and cash equivalents

Cash and cash equivalents are valued at cost, which approximates fair value and are categorized in Level 1 of the fair value hierarchy.

Government securities

Government securities are valued using factors which include but are not limited to market quotations, yields, maturities, and the bond’s terms and conditions. U.S. Treasury securities, valued using quoted market prices, are categorized in Level 1 of the fair value hierarchy. Callable agency-issued debt securities are valued by benchmarking model-derived prices to quoted market prices and trade data for comparable instruments. The fair value of agency mortgage pass-through pool securities is model-driven based on spreads of a comparable to be announced security. For index linked securities, the market price is adjusted daily by the appropriate index factor. The fair value of state and municipal government securities is determined using recently executed transactions, market price quotations or pricing models that factor in, where applicable, interest rates, bond or CDS spreads and volatility. Callable agency-issued debt securities, agency mortgage pass-through pool securities, index linked securities, and state and municipal government securities are generally categorized in Level 2 of the fair value hierarchy.

Corporate debt instruments

Corporate debt instruments are composed of corporate bonds, corporate loans and asset-backed securities. Corporate bonds and corporate loans are valued using factors which include but are not limited to recently executed transactions, observable market price quotations and spreads. Asset-backed securities may be valued based on price or spread data obtained from observed transactions or independent external parties such as vendors or brokers. When position-specific external price data are not observable, the fair value determination may require benchmarking to similar securities. For index linked securities, the market price is adjusted daily by the appropriate index factor. Corporate debt instruments are categorized in Level 2 of the fair value hierarchy.

Derivative investments

Depending on the product and terms of the transaction, the fair value of over-the-counter (“OTC”) derivative products can be either observed or modeled using a series of techniques and model inputs from comparable benchmarks, including closed-form analytic formulas, such as the Black-Scholes option-pricing model, and simulation models or a combination thereof. Many pricing models do not entail material subjectivity as the methodologies employed do not necessitate significant judgment, since

model inputs may be observed from actively quoted markets, as is the case for generic interest rate swaps and certain option contracts. Interest rate swaps are valued using observable inputs. Listed derivatives that are not actively traded are valued using the same approaches as those applied to OTC derivatives. Derivative investments are categorized in Level 2 of the fair value hierarchy.

Repurchase agreements

The fair value of repurchase agreements is computed using a standard cash flow discounting methodology. The inputs to the valuation include contractual cash flows and collateral funding spreads which are estimated using various benchmarks, interest rate yield curves and option volatilities. Repurchase agreements are categorized in Level 2 of the fair value hierarchy.

Collective Trust Funds – Each investment is administered and supervised by its respective investment manager who decides how to invest the contributed funds. The Collective Trust Funds do not have a readily determinable fair value. The fair values of participating units held in the Collective Trust Funds are valued by the investment managers at NAVs and recent transaction prices and therefore are not required to be categorized by Levels of the fair value hierarchy. If there is a fee accrual, the Trustee is responsible for determining the fair value. At December 31, 2018 and 2017, the Plan held investments in funds managed by State Street Global Advisors, BlackRock, Inc., Wellington Management, and PIMCO. At December 31, 2018, the Plan also held investments in funds managed by Morgan Stanley Investment Management. Terms of the applicable Collective Trust Fund Agreements and/or Investment Management Agreements permit the termination of the agreement and the receipt of the fund securities at fair value within 30 days. There were no unfunded commitments and no restricted redemption notice periods. Other than certain funds managed by State Street Global Advisors and BlackRock, Inc., from which the Plan does not restrict the frequency of redemptions, the Plan generally prohibits the sale of the Collective Trust Fund investment options within 30 days of a purchase into that investment option.

The following tables set forth by Level within the fair value hierarchy the Plan’s investment and derivative instrument assets and liabilities at fair value at December 31, 2018 and 2017. There were no transfers of investments between Levels for either year.
