INVESTMENT MANAGEMENT

Welcome, Shareholder:

In this report, you’ll learn about how your investment in Morgan Stanley Mid-Cap Value Fund performed during the semiannual period. We will provide an overview of the market conditions, and discuss some of the factors that affected performance during the reporting period. In addition, this report includes the Fund’s financial statements and a list of Fund investments.

This material must be preceded or accompanied by a prospectus for the fund being offered.

Market forecasts provided in this report may not necessarily come to pass. There is no assurance that the Fund will achieve its investment objective. The Fund is subject to market risk, which is the possibility that market values of securities owned by the Fund will decline and, therefore, the value of the Fund’s shares may be less than what you paid for them. Accordingly, you can lose money investing in this Fund. Please see the prospectus for more complete information on investment risks.

The performance of the Fund’s four share classes varies because each has different expenses. The Fund’s total returns assume the reinvestment of all distributions but do not reflect the deduction of any applicable sales charges. Such costs would lower performance. See Performance Summary for standardized performance and benchmark information.

Market Conditions

In the six-month period ended February 28, 2010, investors continued to gain confidence in an economic recovery, despite mixed economic data in the U.S. and several reminders that the global recovery remained fragile. The broad equity market rose for the period overall.

Although the worst of the financial crisis and economic recession seems to have passed, the recovery still faces many headwinds, most notably lingering high unemployment rates and the still-weak real estate market. While corporate earnings continued to reflect improvement relative to expectations, the improvements were generally attributable to aggressive cost cutting rather than growth in real demand. In early 2010, credit tightening by the Chinese government and the enormous budget deficits in Greece and several other European Union nations raised fears about the strength of the global economy.

However, an uptick in merger and acquisition activity and initial public offerings helped offset some of these concerns. Weakness in the U.S. dollar also supported the market’s rise as cheaper-priced goods in the U.S. bolstered exports. Overall, investors generally shrugged off negative news, contributing to the broad market’s gain for the period.

Performance Analysis

Morgan Stanley Mid-Cap Value Fund Class A, Class B and Class I shares outperformed and Class C shares underperformed the Russell Midcap^® Value Index (the “Index”), and all share classes outperformed the Lipper Mid-Cap Value Funds Index for the six months ended February 28, 2010, assuming no deduction of applicable sales charges.

The top contributors to the Fund’s outperformance relative to the Index included the technology sector. The Fund held an overweight position in the sector and benefited from stock selection in an information technology services provider, which rallied after an announcement that it would be acquired, as well as several software and hardware holdings that performed well during the period. The consumer staples sector also added to relative returns. Within the sector, a holding in a cosmetics company with strong revenue growth in overseas markets and recovering domestic business contributed positively. In the energy sector, a holding in an oil and gas exploration and production company produced gains, as the stock price appreciated on an acquisition announcement.

Although all sectors in the Fund and the Index had positive returns on an absolute basis during the period, performance in some of the Fund’s sectors lagged behind that of the Index. Underweight positions in both the materials and consumer discretionary sectors dampened relative performance. Both sectors performed well as investors expected the global economic recovery to spur demand. Had the portfolio held larger weightings in these sectors, the Fund would have participated more fully in their appreciation. The health care sector was another source of relative weakness. The Fund primarily held a mix of health care equipment and health care services stocks, but had less exposure to some of the better-performing health care services stocks during the period.

There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the Fund in the future.

Investment Strategy

The Fund will normally invest at least 80 percent of its assets in common stock and other equity securities, including depositary receipts and securities convertible into common stock, of companies traded on a U.S. securities exchange with market capitalizations that fall within the range of companies included in the Russell Midcap^® Value Index. As of November 30, 2009, these market capitalizations ranged between $251 million and $13.4 billion. In pursuing its investment objective, the Fund’s “Investment Adviser,” Morgan Stanley Investment Advisors Inc., seeks attractively valued companies experiencing a change that the Investment Adviser believes could have a positive impact on a company’s outlook, such as a change in management, industry dynamics or operational efficiency. In determining whether securities should be sold, the Investment Adviser considers a number of factors, including appreciation to fair value, fundamental changes in the company or changes in economic or market trends. The Investment Adviser may purchase stocks that typically do not pay dividends. The Fund may also use derivative instruments as discussed in the Fund’s prospectus. These derivative instruments will be counted toward the 80 percent policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

Performance data quoted represents past performance, which is no guarantee of future results and current performance may be lower or higher than the figures shown. For most recent month-end performance figures, please visit www.morganstanley.com/im or speak with your Financial Advisor. Investment returns and principal value will fluctuate and fund shares, when redeemed, may be worth more or less than their original cost. The table does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Performance for Class A, Class B, Class C, and Class I shares will vary due to differences in sales charges and expenses. See the Fund’s current prospectus for complete details on fees and sales charges. Expense ratios are as of each Fund’s fiscal year end as outlined in the Fund’s current prospectus.


*		The maximum front-end sales charge for Class A is 5.25%.

**		The maximum contingent deferred sales charge (CDSC) for Class B is 5.0%. The CDSC declines to 0% after six years. For periods greater than eight years, returns do not reflect conversion to Class A shares eight years after the end of the calendar month in which shares were purchased. The conversion feature is currently suspended because the total annual operating expense ratio of Class B is currently lower than that of Class A. See “Conversion Feature” for Class B shares in “Share Class Arrangements” of the Prospectus for more information.

†		The maximum contingent deferred sales charge for Class C is 1.0% for shares redeemed within one year of purchase.

††		Class I has no sales charge.

(1)		The Russell Midcap^® Value Index measures the performance of the mid-cap value segment of the U.S. equity universe. It includes those Russell Midcap^® Index companies with lower price-to-book ratios and lower forecasted growth values. The Russell Midcap^® Index is a subset of the Russell 1000^® Index and includes approximately 800 of the smallest securities in the Russell 1000^® Index, which in turn consists of approximately 1,000 of the largest U.S. securities based on a combination of market capitalization and current index membership. The Index is unmanaged and its returns do not include any sales charges or fees. Such costs would lower performance. It is not possible to invest directly in an index.

(2)		The Lipper Mid-Cap Value Funds Index is an equally weighted performance index of the largest qualifying funds (based on net assets) in the Lipper Mid-Cap Value Funds classification. The Index, which is adjusted for capital gains distributions and income dividends, is unmanaged and should not be considered an investment. There are currently 30 funds represented in this Index. The Fund was in the Lipper Mid-Cap Value Funds classification as of the date of this report.

(3)		Figure shown assumes reinvestment of all distributions and does not reflect the deduction of any sales charges.

(4)		Figure shown assumes reinvestment of all distributions and the deduction of the maximum applicable sales charge. See the Fund’s current prospectus for complete details on fees and sales charges.

Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and (2) ongoing costs, including advisory fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 09/01/09 – 02/28/10.

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of the table is useful in comparing ongoing costs, and will not help you determine the relative total cost of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.


	Beginning		Ending		Expenses Paid
	Account Value		Account Value		During Period@
					09/01/09 –
	09/01/09		02/28/10		02/28/10
Class A
Actual (13.85% return)	$	1,000.00	$	1,138.50	$	8.59
Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,016.76	$	8.10

Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,018.00	$	6.85


@		Expenses are equal to the Fund’s annualized expense ratios of 1.62%, 1.96%, 2.37% and 1.37% for Class A, Class B, Class C and Class I shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). If the Fund had borne all of its expenses, the annualized expense ratios would have been 1.63%, 1.97%, 2.38% and 1.38% for Class A, Class B, Class C and Class I shares, respectively.

Morgan Stanley Mid-Cap Value Fund

Notes to Financial Statements - February 28, 2010 (unaudited)

1. Organization and Accounting Policies

Morgan Stanley Mid-Cap Value Fund (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company. The Fund’s investment objective is above-average total return. The Fund was organized as a Massachusetts business trust on April 12, 2001 and commenced operations on October 29, 2001.

The Fund offers Class A shares, Class B shares, Class C shares and Class I shares. The four classes are substantially the same except that most Class A shares are subject to a sales charge imposed at the time of purchase and some Class A shares, and most Class B shares and Class C shares are subject to a contingent deferred sales charge imposed on shares redeemed within eighteen months, six years and one year, respectively. Class I shares are not subject to a sales charge. Additionally, Class A shares, Class B shares and Class C shares incur distribution expenses.

Morgan Stanley announced on October 19, 2009 that it has entered into a definitive agreement to sell substantially all of its retail asset management business to Invesco Ltd. (“Invesco”), a leading global investment management company. The Trustees of the Fund approved an Agreement and Plan of Reorganization (the “Plan”). Pursuant to the Plan, substantially all of the assets of the Fund would be combined with those of a newly organized mutual fund advised by an affiliate of Invesco Ltd. (the “New Fund”). Pursuant to the Plan, shareholders of the Fund would become shareholders of the New Fund, receiving shares of such New Fund equal to the value of their holdings in the Fund. The Plan is subject to the approval of the Fund’s shareholders at a special meeting of shareholders anticipated to be held during the second quarter of 2010.

The following is a summary of significant accounting policies:

A. Valuation of Investments — (1) an equity portfolio security listed or traded on the New York Stock Exchange (“NYSE”) or American Stock Exchange or other exchange is valued at its latest sale price prior to the time when assets are valued; if there were no sales that day, the security is valued at the mean between the last reported bid and ask price; (2) an equity portfolio security listed or traded on the Nasdaq is valued at the Nasdaq Official Closing Price; if there were no sales that day, the security is valued at the mean between the last reported bid and ask price; (3) all other portfolio securities for which over-the-counter market quotations are readily available are valued at the mean between the last reported bid and ask price. In cases where a security is traded on more than one exchange, the security is valued on the exchange designated as the primary market; (4) for equity securities traded on foreign exchanges, the last reported sale price or the latest bid price may be used if there were no sales on a particular day; (5) when market quotations are not readily available including circumstances under which Morgan Stanley Investment Advisors Inc. (the “Investment Adviser”) determines that the latest sale price, the bid price or the mean between the

Morgan Stanley Mid-Cap Value Fund

Notes to Financial Statements - February 28, 2010 (unaudited) continued

last reported bid and ask price do not reflect a security’s market value, portfolio securities are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Fund’s Trustees. Occasionally, developments affecting the closing prices of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the foreign market on which the securities trade) and the close of business on the NYSE. If developments occur during such periods that are expected to materially affect the value of such securities, such valuations may be adjusted to reflect the estimated fair value of such securities as of the close of the NYSE, as determined in good faith by the Fund’s Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trustees of the Fund; (6) certain portfolio securities may be valued by an outside pricing service approved by the Fund’s Trustees; (7) investments in open-end mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close of each business day; and (8) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost, which approximates market value.

B. Accounting for Investments — Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Dividend income and other distributions are recorded on the ex-dividend date. Discounts are accreted and premiums are amortized over the life of the respective securities and are included in interest income. Interest income is accrued daily as earned.

C. Multiple Class Allocations — Investment income, expenses (other than distribution fees), and realized and unrealized gains and losses are allocated to each class of shares based upon the relative net asset value on the date such items are recognized. Distribution fees are charged directly to the respective class.

D. Federal Income Tax Policy — It is the Fund’s policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. The Fund files tax returns with the U.S. Internal Revenue Service, New York State and New York City. The Fund recognizes the tax effects of a tax position taken or expected to be taken in a tax return only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date. The more-likely-than-not threshold must continue to be met in each reporting period to support continued recognition of the benefit. The difference between the tax benefit recognized in the financial statements for a tax position taken and the tax benefit claimed in the income tax return is referred to as an unrecognized tax benefit. There are no unrecognized tax benefits in the accompanying financial statements. If applicable, the Fund recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in

Morgan Stanley Mid-Cap Value Fund

Notes to Financial Statements - February 28, 2010 (unaudited) continued

the Statement of Operations. Each of the tax years filed in the four-year period ended August 31, 2009, remains subject to examination by taxing authorities.

E. Dividends and Distributions to Shareholders — Dividends and distributions to shareholders are recorded on the ex-dividend date.

F. Use of Estimates — The preparation of financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates.

G. Subsequent Events — The Fund considers events or transactions that occur after the date of the Statement of Assets and Liabilities but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements.

2. Fair Valuation Measurements

Fair value is defined as the price that the Fund would receive to sell an investment or pay to transfer a liability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. GAAP utilizes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Fund’s investments. The inputs are summarized in the three broad levels listed below.


	•	Level 1 — unadjusted quoted prices in active markets for identical investments

	•	Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

	•	Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each security.

3. Investment Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement with the Investment Adviser, the Fund pays an advisory fee, accrued daily and payable monthly, by applying the following annual rates to the net assets of the Fund

Morgan Stanley Mid-Cap Value Fund

Notes to Financial Statements - February 28, 2010 (unaudited) continued

determined at the close of each business day: 0.72% to the portion of the daily net assets not exceeding $1 billion and 0.65% to the portion of the daily net assets exceeding $1 billion.

Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the “Administrator”), an affiliate of the Investment Adviser, the Fund pays an administration fee, accrued daily and payable monthly, by applying the annual rate of 0.08% to the Fund’s daily net assets.

Under an agreement between the Administrator and State Street Bank and Trust Company (“State Street”), State Street provides certain administrative services to the Fund. For such services, the Administrator pays State Street a portion of the fee the Administrator receives from the Fund.

4. Plan of Distribution

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the “Distributor”), an affiliate of the Investment Adviser and Administrator. The Fund has adopted a Plan of Distribution (the “Plan”) pursuant to Rule 12b-1 under the Act. The Plan provides that the Fund will pay the Distributor a fee which is accrued daily and paid monthly at the following annual rates: (i) Class A – up to 0.25% of the average daily net assets of Class A shares; (ii) Class B – up to 1.0% of the average daily net assets of Class B shares; and (iii) Class C – up to 1.0% of the average daily net assets of Class C shares.

In the case of Class B shares, provided that the Plan continues in effect, any cumulative expenses incurred by the Distributor but not yet recovered may be recovered through the payment of future distribution fees from the Fund pursuant to the Plan and contingent deferred sales charges paid by investors upon redemption of Class B shares. Although there is no legal obligation for the Fund to pay expenses incurred in excess of payments made to the Distributor under the Plan and the proceeds of contingent deferred sales charges paid by investors upon redemption of shares, if for any reason the Plan is terminated, the Trustees will consider at that time the manner in which to treat such expenses. The Distributor has advised the Fund that there were no excess expenses at February 28, 2010. For the six months ended February 28, 2010, the distribution fee was accrued for Class B at an annual rate of 0.59%.

As February 28, 2010, included in the Statement of Assets and Liabilities, is a receivable from the Fund’s Distributor which represents payments due to be reimbursed to the Fund under the Plan. Because the Plan is what is referred to as a “reimbursement plan”, the Distributor reimburses to the Fund any 12b-1 fees collected in excess of the actual distribution expenses incurred. This receivable represents this excess amount as of February 28, 2010.

In the case of Class A shares and Class C shares, expenses incurred pursuant to the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily net assets of Class A or Class C, respectively, will not be reimbursed by the Fund through payments in any subsequent year, except that expenses representing a gross sales credit to Morgan Stanley Financial Advisors and other authorized financial representatives at the

Morgan Stanley Mid-Cap Value Fund

Notes to Financial Statements - February 28, 2010 (unaudited) continued

time of sale may be reimbursed in the subsequent calendar year. For the six months ended February 28, 2010, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.25% and 1.0%, respectively.

The Distributor has informed the Fund that for the six months ended February 28, 2010, it received contingent deferred sales charges from certain redemptions of the Fund’s Class A shares, Class B shares and Class C shares of $3, $3,105 and $311, respectively and received $773 in front-end sales charges from sales of the Fund’s Class A shares. The respective shareholders pay such charges which are not an expense of the Fund.

5. Security Transactions and Transactions with Affiliates

The Fund invests in Morgan Stanley Institutional Liquidity Funds – Money Market Portfolio – Institutional Class, an open-end management investment company managed by an affiliate of the Investment Adviser. Investment advisory fees paid by the Fund are reduced by an amount equal to the advisory and administrative service fees paid by Morgan Stanley Institutional Liquidity Funds – Money Market Portfolio – Institutional Class with respect to assets invested by the Fund in Morgan Stanley Institutional Liquidity Funds – Money Market Portfolio – Institutional Class. For the six months ended February 28, 2010, advisory fees paid were reduced by $2,779 relating to the Fund’s investment in Morgan Stanley Institutional Liquidity Funds – Money Market Portfolio – Institutional Class. Income distributions earned by the Fund are recorded as “dividends from affiliate” in the Statement of Operations and totaled $3,103 for the six months ended February 28, 2010. During the six months ended February 28, 2010, the cost of purchases and sales of investments in Morgan Stanley Institutional Liquidity Funds – Money Market Portfolio – Institutional Class aggregated $23,545,074 and $22,299,302, respectively.

The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the six months ended February 28, 2010 aggregated $30,202,158 and $38,664,130, respectively. Included in the aforementioned transactions are sales of $957,540 with other Morgan Stanley funds resulting in net realized losses of $148,773.

For the six months ended February 28, 2010, the Fund incurred brokerage commissions of $7,605 with Morgan Stanley & Co., Inc. an affiliate of the Investment Adviser, Administrator and Distributor, for portfolio transactions executed on behalf of the Fund.

For the six months ended February 28, 2010, the Fund incurred brokerage commissions of $1,524 with Citigroup, Inc., an affiliate of the Investment Adviser, Administrator and Distributor, for portfolio transactions executed on behalf of the Fund.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and Distributor, is the Fund’s transfer agent.

Morgan Stanley Mid-Cap Value Fund

Notes to Financial Statements - February 28, 2010 (unaudited) continued

The Fund has an unfunded Deferred Compensation Plan (the “Compensation Plan”) which allows each independent Trustee to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Trustees. Each eligible Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund.

6. Federal Income Tax Status

The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations which may differ from GAAP. These “book/tax” differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in-capital.

As of August 31, 2009, the Fund had temporary book/tax differences primarily attributable to post-October losses (capital losses incurred after October 31 within the taxable year which are deemed to arise on the first business day of the Fund’s next taxable year), and capital loss deferrals on wash sales.

8. New Accounting Pronouncement

On January 21, 2010, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2010-06. The ASU amends Accounting Standards Codification 820 to add new requirements for disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements. It also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques in Level 2 and Level 3 fair value measurements. The application of ASU 2010-06 is required for fiscal years and interim periods beginning after December 15, 2009, except for disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements, which are required for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. At this time, the Fund’s management is evaluating the implications of ASU 2010-06 on the Fund’s financial statements.

This Policy applies to current and former individual clients of Morgan Stanley Distributors Inc., as well as current and former individual investors in Morgan Stanley mutual funds and related companies.

This Policy is not applicable to partnerships, corporations, trusts or other non-individual clients or account holders, nor is this Policy applicable to individuals who are either beneficiaries of a trust for which we serve as trustee or participants in an employee benefit plan administered or advised by us. This Policy is, however, applicable to individuals who select us to be a custodian of securities or assets in individual retirement accounts, 401(k) accounts, 529 Educational Savings Accounts, accounts subject to the Uniform Gifts to Minors Act, or similar accounts.

This Policy describes what non-public personal information we collect about you, how we collect it, when we may share it with others, and how others may use it. It discusses the steps you may take to limit our sharing of information about you with affiliated Morgan Stanley companies (“affiliated companies”). It also discloses how you may limit our affiliates’ use of shared information for marketing purposes. Throughout this Policy, we refer to the non-public information that personally identifies you or your accounts as “personal information.”
