INVESTMENT MANAGEMENT

Welcome, Shareholder:

In this report, you'll learn about how your investment in Morgan Stanley High Yield Securities Inc. performed during the annual 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.

Fund Report

Total Return for the 12 Months Ended August 31, 2009

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

The fiscal year ended August 31, 2009 was composed of two distinct periods in terms of market performance. During the first period, or the last four months of 2008, the credit crisis was at its peak. Following the bankruptcy of Lehman Brothers and the government takeover of Fannie Mae and Freddie Mac in September, the credit markets seized up. Over the next several weeks the credit crisis intensified while at the same time, fears of a severe economic recession emerged. Together these factors led to a significant sell-off of risky assets that continued through the end of the year and as a result, for the period from September 1 through December 31, 2008, the high yield bond market declined 24.35 percent, as measured by the Barclays Capital U.S. Corporate High Yield-2% Issuer Cap Index (the "Index").

Year to date, however, has been a completely different story. As we entered the year, signs of economic stabilization began to appear, credit concerns eased, consumer confidence improved, and investors began to take on risk again, spurring a rebound in high yield bond prices that continued through the end of the reporting period. Year-to-date through the end of August, the high yield bond market gained 41.44 percent (as measured by the Index), which more than made up for the losses experienced in the last four months of 2008 and resulted in a 7.0 percent Index return for the 12-month reporting period. More than $15 billion in new money has flowed into the high yield asset class year-to-date, sparking a resurgence of the new issue market, with many issuers pricing new bonds this year.

Industry returns for the period varied widely. The best performing industries within the Index for the 12-month reporting period were insurance (+53.5 percent), financials (+41.1 percent) and transportation (+13.3 percent), while the worst performers were basic industry (–5.6 percent), communications (–2.7 percent), and utilities (–2.3 percent).

Performance Analysis

All share classes of Morgan Stanley High Yield Securities Inc. underperformed the Barclays Capital U.S. Corporate High Yield-2% Issuer Cap Index (the "Index") and outperformed the Lipper High Current Yield Bond Funds

2

Index for the 12 months ended August 31, 2009, assuming no deduction of applicable sales charges.

The primary contributor to the Fund's underperformance relative to the Index was the portfolio's more defensive positioning. Throughout the period, the Fund had an emphasis on higher quality issuers with strong asset values. In addition, the Fund has de-emphasized highly cyclical (or economically sensitive) industries and focused on more stable industry groups that have performed relatively well throughout an economic cycle. This strategy benefited performance as the market declined and the riskiest segments of the market experienced the most significant losses. More recently, however, the Fund's defensive positioning has detracted from returns as the lowest quality issuers have experienced the most dramatic positive returns. For the overall period, therefore, this positioning was a drag on relative performance.

From an industry perspective, the Fund benefited from an underweight in the building materials industry as this segment underperformed, and from an overweight in the health care industry which performed relatively well. Conversely, overweights in media and cable and an underweight in the automotive industry detracted from relative performance for the period.

The market turbulence over the past year has created opportunities for high yield investors and we continue to find compelling values within the asset class. We remain concerned over the lowest quality issuers in the market as we believe they remain vulnerable in a rising default environment. In our view, there are more compelling risk/reward opportunities within higher quality issuers in the market and therefore, the Fund continues to emphasize higher quality bonds.

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 fixed-income securities (including zero coupon securities) rated below Baa by Moody's Investors Service, Inc. ("Moody's") or below BBB by Standard & Poor's Rating Group, a division of The McGraw-Hill Companies, Inc. ("S&P"), or in non-rated securities considered by the Fund's "Investment Adviser," Morgan Stanley Investment Advisors Inc., to be appropriate investments for the Fund. Such securities may also include "Rule 144A" securities, which are subject to resale restrictions. Shareholders of the Fund will receive at least 60 days' prior notice of any changes in this policy. 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. Sec urities rated below Baa or BBB are commonly known as "junk bonds." There are no minimum quality ratings for investments, and as such the Fund may invest in securities which no longer make payments of interest or principal, including defaulted securities.

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 graph and table do 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.

Prior to July 28, 1997 the Fund offered only one class of shares. Because the distribution arrangement for Class A most closely resembled the distribution arrangement applicable prior to the implementation of multiple classes (i.e., Class A is sold with a front-end sales charge), historical performance information has been restated to reflect the actual maximum sales charge applicable to Class A (i.e., 4.25%) as compared to the 5.50% sales charge in effect prior to July 28, 1997. In addition, Class A shares are now subject to an ongoing 12b-1 fee which is reflected in the restated performance for that class.

Because all shares of the Fund held prior to July 28, 1997 were designated Class I shares (formerly Class D shares), the Fund's historical performance has been restated to reflect the absence of any sales charge.

*  The maximum front-end sales charge for Class A is 4.25%.

**  The maximum contingent deferred sales charge (CDSC) for Class B is 5.0%. The CDSC declines to 0% after six years. Effective April 2005, Class B shares will generally convert to Class A shares approximately eight years after the end of the calendar month in which the shares were purchased. Performance for periods greater than eight years reflects this conversion.

†  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 Barclays Capital U.S. Corporate High Yield – 2% Issuer Cap Index is the 2% Issuer Cap component of the Barclays Capital U.S. Corporate High Yield Index which covers the U.S. dollar-denominated, non-investment grade, fixed-rate, taxable corporate bond market. Securities are classified as high-yield if the middle rating of Moody's, Fitch, and S&P is Ba1/BB+/BB+ or below. The Index excludes Emerging Markets debt. 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 High Current Yield Bond Funds Index is an equally weighted performance index of the largest qualifying funds (based on net assets) in the Lipper High Current Yield Bond 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 High Current Yield Bond 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 redemption fees; 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 03/01/09 – 08/31/09.

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) and redemption fees. 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 Account Value		Ending Account Value		Expenses Paid During Period@
	03/01/09		08/31/09		03/01/09 – 08/31/09
Class A
Actual (32.48% return)	$	1,000.00	$	1,324.80	$	12.89
Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,014.12	$	11.17
Class B
Actual (31.75% return)	$	1,000.00	$	1,317.50	$	15.77
Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,011.59	$	13.69
Class C
Actual (32.18% return)	$	1,000.00	$	1,321.80	$	16.39
Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,011.09	$	14.19

Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,015.38	$	9.91

  @  Expenses are equal to the Fund's annualized expense ratios of 2.20%, 2.70%, 2.80% and 1.95% for Class A, Class B, Class C and Class I shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

Investment Advisory Agreement Approval

Nature, Extent and Quality of Services

The Board reviewed and considered the nature and extent of the investment advisory services provided by the Investment Adviser (as defined herein) under the advisory agreement, including portfolio management, investment research and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Fund's Administrator (as defined herein) under the administration agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Investment Adviser's expense. (The Investment Adviser and the Administrator together are referred to as the "Adviser" and the advisory and administration agreements together are referred to as the "Management Agreement.") The Board also compared the nature of the services provided by the Adviser with similar services pr ovided by non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper").

The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the advisory and administrative services to the Fund. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Fund. The Board also concluded that the overall quality of the advisory and administrative services was satisfactory.

Performance, Fees and Expenses of the Fund

The Board reviewed the performance, fees and expenses of the Fund compared to its peers, as determined by Lipper, and to appropriate benchmarks where applicable. The Board discussed with the Adviser the performance goals and the actual results achieved in managing the Fund. When considering a fund's performance, the Board and the Adviser place emphasis on trends and longer-term returns (focusing on one-year, three-year and five-year performance, as of December 31, 2008, as applicable). When a fund underperforms its benchmark and/or its peer group average, the Board and the Adviser discuss the causes of such underperformance and, where necessary, they discuss specific changes to investment strategy or investment personnel. The Board noted that the Fund's performance was better than its peer group average for the one-, three- and five-year periods. The Board discussed with the Adviser the level of the advisory and administration f ees (together, the "management fee") for this Fund relative to comparable funds advised by the Adviser and compared to its peers as determined by Lipper. In addition to the management fee, the Board also reviewed the Fund's total expense ratio. The Board noted that while the management fee was lower than the peer group average, the total expense ratio was higher than the peer group average. After discussion, the Board concluded that the Fund's management fee and performance were competitive with the peer group average, and the total expense ratio was acceptable.

9

Economies of Scale

The Board considered the size and growth prospects of the Fund and how that relates to the Fund's total expense ratio and particularly the Fund's management fee rate, which includes breakpoints. In conjunction with its review of the Adviser's profitability, the Board discussed with the Adviser how a change in assets can affect the efficiency or effectiveness of managing the Fund and whether the management fee level is appropriate relative to current and projected asset levels and/or whether the management fee structure reflects economies of scale as asset levels change. The Board has determined that its review of the actual and potential economies of scale of the Fund support its decision to approve the Management Agreement.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and its affiliates during the last year from their relationship with the Fund and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. The Board has determined that its review of the analysis of the Adviser's expenses and profitability supports its decision to approve the Management Agreement.

Other Benefits of the Relationship

The Board considered other benefits to the Adviser and its affiliates derived from their relationship with the Fund and other funds advised by the Adviser. These benefits may include, among other things, "float" benefits derived from handling of checks for purchases and sales, research received by the Adviser generated from commission dollars spent on funds' portfolio trading and fees for distribution and/or shareholder servicing. The Board reviewed with the Adviser each of these arrangements and the reasonableness of its costs relative to the services performed. The Board has determined that its review of the other benefits received by the Adviser or its affiliates supports its decision to approve the Management Agreement.

Resources of the Adviser and Historical Relationship Between the Fund and the Adviser

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board also reviewed and considered the historical relationship between the Fund and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Fund's operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement and that it is beneficial for the Fund to continue its relationship with the Adviser.

10

Other Factors and Current Trends

The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Fund's Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Fund's business.

General Conclusion

After considering and weighing all of the above factors, the Board concluded that it would be in the best interest of the Fund and its shareholders to approve renewal of the Management Agreement for another year. In reaching this conclusion the Board did not give particular weight to any single factor referenced above. The Board considered these factors over the course of numerous meetings, some of which were in executive session with only the Independent Board members and their counsel present. It is possible that individual Board members may have weighed these factors differently in reaching their individual decisions to approve the Management Agreement.

1. Organization and Accounting Policies

Morgan Stanley High Yield Securities Inc. (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 seeks as a primary objective to earn a high level of current income. As a secondary objective, the fund seeks capital appreciation but only to the extent consistent with its primary objective. The Fund was incorporated in Maryland on June 14, 1979 and commenced operations on September 26, 1979. On July 28, 1997, the Fund converted to a multiple class share structure.

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.

The Fund will assess a 2% redemption fee, on Class A shares, Class B shares, Class C shares, and Class I shares, which is paid directly to the Fund, for shares redeemed or exchanged within thirty days of purchase, subject to certain exceptions. The redemption fee was designed to protect the Fund and its remaining shareholders from the effects of short-term trading.

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 design ated 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) credit default/interest rate swaps are marked-to-market daily based upon quotations from market makers; (6) futures are valued at the latest price published by the commodities exchange on which they trade; (7) 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 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

25

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

Fund's Directors. 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 Directors or by the Investment Adviser using a pricing service and/or procedures approved by the Directors of the Fund; (8) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Directors; (9) investments in open-end mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the c lose of each business day; and (10) 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 except where collection is not expected.

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. Futures — A futures contract is an agreement between two parties to buy and sell financial instruments or contracts based on financial indices at a set price on a future date. Upon entering into such a contract, the Fund is required to pledge to the broker cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as variation margin are recorded by the Fund as unrealized gains and losses. Upon closing of the contract, the Fund realizes a gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

E. Foreign Currency Translation and Forward Foreign Currency Contracts — The books and records of the Fund are maintained in U.S. dollars as follows: (1) the foreign currency market value of

26

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

investment securities, other assets and liabilities and forward foreign currency contracts ("forward contracts") are translated at the exchange rates prevailing at the end of the period; and (2) purchases, sales, income and expenses are translated at the exchange rates prevailing on the respective dates of such transactions. The resultant exchange gains and losses are recorded as realized and unrealized gains/losses on forward foreign exchange contracts and foreign currency translations. Pursuant to U.S. federal income tax regulations, certain foreign exchange gains/losses included in realized and unrealized gains/losses are included in or are a reduction of ordinary income for federal income tax purposes. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in the market prices of the securities. Forward contracts are valued daily at th e appropriate exchange rates. The resultant unrealized exchange gains and losses are recorded as unrealized foreign currency gains or losses. The Fund records realized gains or losses on delivery of the currency or at the time the forward contract is extinguished (compensated) by entering into a closing transaction prior to delivery.

F. Swaps — The Fund may enter into credit default swap contracts, a type of credit derivative, for hedging purposes or to gain exposure to a credit or index of credits in which the Fund may otherwise invest. A credit default swap is an agreement between two parties to exchange the credit risk of an issuer or index of issuers. A buyer of a credit default swap is said to buy protection by paying periodic fees in return for a contingent payment from the seller if the issuer has a credit event such as bankruptcy, a failure to pay outstanding obligations or deteriorating credit while the swap is outstanding. A seller of a credit default swap is said to sell protection and thus collects the periodic fees and profits if the credit of the issuer remains stable or improves while the swap is outstanding. The seller in a credit default swap contract would b e required to pay an agreed upon amount, to the buyer in the event of an adverse credit event of the issuer. This agreed-upon amount approximates the notional amount of the swap and is estimated to be the maximum potential future payment that the seller could be required to make under the credit default swap contract. In the event of an adverse credit event, the seller generally does not have any contractual remedies against the issuer or any other third party. However, if a physical settlement is elected, the seller would receive the defaulted credit and, as a result, become a creditor of the issuer.

The current credit rating of each individual issuer serves as indicator of the current status of the payment/performance risk of the credit derivative. Alternatively, for credit default swaps on an index of credits, the quoted market prices and current values serve as an indicator of the current status of the payment/performance risk of the credit derivative. Generally, lower credit ratings and increasing market values, in absolute terms, represent a deterioration of the credit and a greater likelihood of an adverse credit event of the issuer.

27

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

The Fund accrues for the periodic fees on credit default swaps on a daily basis as earned with the net amount accrued recorded within realized gains/losses on swap contracts on the Statement of Operations. Net unrealized gains are recorded as an asset or net unrealized losses are reported as a liability on the Statement of Assets and Liabilities. The change in value of the swap contracts is reported as unrealized gains or losses on the Statement of Operations. Payments received or made upon entering into a credit default swap contract, if any, are recorded as realized gains or losses on the Statement of Operations upon termination or maturity of the swap. Credit default swaps may involve greater risks than if a Fund had invested in the issuer directly. Credit default swaps are subject to general market risk, counterparty risk and credit risk.

The Fund may also enter into interest rate swaps and asset swaps (where parties combine the purchase or sale of a bond/note with an interest rate swap) ("swaps") primarily to preserve a return or spread on a particular investment or portion of its portfolio, as a duration management technique or to protect against any increase in the price of securities the Fund anticipates purchasing at a later date. Swaps are contractual agreements to exchange periodic interest payment streams calculated on a predetermined notional principal amount. Swaps generally involve one party paying a fixed interest rate and the other party paying a variable rate. The Fund will usually enter into swaps on a net basis, i.e, the two payment streams are netted out in a cash settlement on the payment date or date specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The Fund accrues the net amount with respect to each swap on a daily basis. This net amount is recorded within realized gains/losses on swap contracts on the Statement of Operations. Risk may arise as a result of the potential inability of the counterparties to meet the terms of the contracts.

Swap agreements are not entered into or traded on exchanges and there is no central clearing or guaranty function for swaps. Therefore, swaps are subject to the risk of default or non-performance by the counterparty. If there is a default by the counterparty to a swap agreement, the Fund will have contractual remedies pursuant to the agreements related to the transaction. Counterparties are required to pledge collateral daily (based on the valuation of each swap) on behalf of the Fund with a value approximately equal to the amount of any unrealized gain. Reciprocally, when the Fund has an unrealized loss on a swap contract, the Fund has instructed the custodian to pledge cash or liquid securities as collateral with a value approximately equal to the amount of the unrealized loss. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate. For cash collateral received, the Fund pays a mon thly fee to the counterparty based on the effective rate for Federal Funds.

G. Senior Loans — The Fund invests in Senior Loans to Borrowers. Senior Loans are typically structured by a syndicate of lenders ("Lenders"), one or more of which administers the Senior Loan on behalf of the Lenders ("Agent"). Lenders may sell interests in Senior Loans to third parties

28

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

("Participations") or may assign all or a portion of their interest in a Senior Loan to third parties ("Assignments"). Senior Loans are exempt from registration under the Securities Act of 1933. Presently, Senior Loans are not readily marketable and are often subject to restrictions on resale.

H. Security Lending — The Fund may lend securities to qualified financial institutions, such as broker-dealers, to earn additional income. Any increase or decrease in the fair value of the securities loaned that might occur and any interest earned or dividends declared on those securities during the term of the loan would remain in the Fund. The Fund receives cash or securities as collateral in an amount equal to or exceeding 100% of the current fair value of the loaned securities. The collateral is marked-to-market daily, by the securities lending agent, to ensure that a minimum of 100% collateral coverage is maintained.

Based on pre-established guidelines, the securities lending agent invests any cash collateral that is received in high-quality short-term investments. Securities lending income is generated from the earnings on the invested collateral and borrowing fees, less any rebates owed to the borrowers and compensation to the lending agent.

The value of loaned securities and related collateral outstanding at August 31, 2009 were $23,665,575 and $24,917,944, respectively. The Fund received cash collateral which was subsequently invested in Repurchase Agreements and Morgan Stanley Institutional Liquidity Funds as reported in the Portfolio of Investments. The Fund has the right under the lending agreement to recover the securities from the borrower on demand.

I. 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 follows the provisions of the Financial Accounting Standards Board ("FASB") Interpretation No. 48, Accounting for Uncertainty in Income Taxes ("FIN 48"). FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. 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 the Statement of Operations. Each of the tax years in the four year period ended August 31, 2009, remains subject to examination by taxing authorities.

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

29

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

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

L. 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 October 29, 2009, the date of issuance of these financial statements.

2. Fair Valuation Measurements

The Fund adopted FASB Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), effective September 1, 2008. In accordance with SFAS 157, 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. SFAS 157 establishes 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.

The following is the summary of the inputs used as of August 31, 2009 in valuing the Fund's investments carried at value:

On April 9, 2009, FASB issued Staff Position No. 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly ("FSP 157-4"). FSP 157-4 provides additional guidance for estimating fair value in accordance with SFAS 157, when the volume and level of activity for the asset or liability have significantly decreased. FSP 157-4 also requires additional disaggregation of the current SFAS 157 required disclosures. FSP 157-4 is effective for interim and annual reporting periods ending after June 15, 2009. The Fund has adopted the provisions of FSP 157-4 as of August 31, 2009 and it did not have a material impact on the Fund's financial statements.

3. Derivative Financial Instruments

The Fund adopted FASB Standard No. 161, Disclosures about Derivative Instruments and Hedging Activities ("SFAS 161"), effective March 1, 2009. SFAS 161 is intended to improve financial reporting about derivative instruments by requiring enhanced disclosures to enable investors to better understand how and why the Fund uses derivative instruments, how these derivative instruments are accounted for and their effects on the Fund's financial position and results of operations.

A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index.

The Fund may use derivative instruments for a variety of reasons, such as to attempt to protect the Fund against possible changes in the market value of its portfolio or to manage the Fund's foreign currency exposure or to generate potential gain. All of the Fund's portfolio holdings, including derivative instruments, are marked-to-market each day with the change in value reflected in unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a contract. In these instances, the recognition of gain or loss is postponed until the disposal of the security underlying the contract. Risk may arise as a result of the potential inability of the counterparties to meet the terms of their contracts.

Summarized below are specific types of derivative financial instruments used by the Fund.

Forward Foreign Currency Contracts The Fund may enter into forward contracts for many purposes, including to facilitate settlement of foreign currency denominated portfolio transactions or to manage foreign currency exposure associated with foreign currency denominated securities. Forward contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the foreign exchange rates underlying the forward contracts. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

32

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

During the year ended August 31, 2009, the cost of purchases and the proceeds from sales of forward foreign currency contracts were $1,383,904 and $2,114,274, respectively.

Futures To hedge against adverse interest rate, the Fund may purchase and sell interest rate futures contracts ("futures contracts"). These futures contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the value of the underlying securities. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

Transactions in futures contracts for the year ended August 31, 2009, were as follows:

	NUMBER OF CONTRACTS
Futures, outstanding at beginning of the period		475
Futures opened		149
Futures closed		(624	)
Futures, outstanding at end of the period		—

Swaps The Fund may enter into interest rate swaps and asset swaps (where parties combine the purchase or sale of a bond/note with an interest rate swap) ("swaps") and may purchase or sell interest rate caps, floors and collars. The Fund expects to enter into these transactions primarily to manage interest rate risk, hedge portfolio positions and preserve a return or spread on a particular investment or portion of its portfolio. The Fund may also enter into these transactions to protect against any increase in the price of securities the Fund anticipates purchasing at a later date. Swap transactions are subject to market risk, risk of default by the other party to the transaction, risk of imperfect correlation and manager risk. Such risks may exceed the related amounts shown in the Statement of Assets and Liabilities.

The Fund may enter into credit default swaps for hedging purposes, to add leverage to its portfolio or to gain exposure to a credit in which the Fund may otherwise invest. Credit default swaps may involve greater risks than if the Fund had invested in the issuer directly. Credit default swaps are subject to general market risk, counterparty risk and credit risk. If the Fund is a buyer and no credit event occurs, it will lose its investment. In addition, if the Fund is a seller and a credit event occurs, the value of the referenced obligation received by the Fund coupled with the periodic payments previously received may be less than the maximum payout amount it pays to the buyer, resulting in a loss to the Fund.

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.

5. 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 0.75% of the average daily net assets of Class B shares; and (iii) Class C — up to 0.85% 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 Directors will consider at that time the manner in which to treat such expenses. The Distributor has advised the Fund that such excess amounts totaled $65,853,588 at August 31, 2009.

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 0.85% 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 time of sale may be reimbursed in the subsequent calendar year. For the year ended August 31, 2009, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.25% and 0.85%, respectively.

The Distributor has informed the Fund that for the year ended August 31, 2009, it received contingent deferred sales charges from certain redemptions of the Fund's Class A shares, Class B shares and Class C shares of $142, $53,646 and $628, respectively and received $10,095 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.

6. 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 year ended August 31, 2009, advisory fees paid were reduced by $6,420 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 $ 33,146 for year ended August 31, 2009. During the year ended August 31, 2009, the cost of purchases and sales of investments in Morgan Stanley Institutional Liquidity Funds – Money Market Portfolio – Institutional Class aggregated $219,438,929 and $214,202,908, respectively.

At August 31, 2009, the Fund held a repurchase agreement with Citigroup Inc, an affiliate of the Investment Adviser, Administrator and Distributor since June 1, 2009, with a value of $1,463,569 in connection with cash collateral received from securities lending.

The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended August 31, 2009, aggregated $100,329,803, and $121,687,662 respectively.

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

The Fund has an unfunded noncontributory defined benefit pension plan covering certain independent Directors of the Fund who will have served as independent Directors for at least five years at the time of retirement. Benefits under this plan are based on factors which include years of service and compensation. The Directors voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003. Aggregate pension costs for the year ended August 31, 2009, included in "directors' fees and expenses" in the Statement of Operations amounted to $15,023. At August 31, 2009, the Fund had an accrued pension liability of $116,078, which is included in "accrued expenses and other payables" in the Statement of Assets and Liabilities.

The Fund has an unfunded Deferred Compensation Plan (the "Compensation Plan") which allows each independent Director to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Directors. Each eligible Director 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.

8. Purposes of and Risks Relating to Certain Financial Instruments

The Fund may lend securities to qualified financial institutions, such as broker-dealers, to earn additional income. Risks in securities lending transactions are that a borrower may not provide additional collateral when required or return the securities when due, and that the value of the short-term investments will be less than the amount of cash collateral plus any rebate that is required to be returned to the borrower.

9. Expense Offset

The expense offset represents a reduction of the fees and expenses for interest earned on cash balances maintained by the Fund with the transfer agent. For the year ended August 31, 2009, the Fund did not have an expense offset.

10. 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 generally accepted accounting principles. 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.

The tax character of distributions paid was as follows:

	FOR THE YEAR ENDED AUGUST 31, 2009			FOR THE YEAR ENDED AUGUST 31, 2008
Ordinary income	$	11,766,478		$	12,305,934
As of August 31, 2009, the tax-basis components of accumulated losses were as follows:
Undistributed ordinary income	$	2,038,387
Undistributed long-term gains		—
Net accumulated earnings		2,038,387
Capital loss carryforward		(1,831,201,462	)
Post-October losses		(70,760,759	)
Temporary differences		(1,342,118	)
Net unrealized depreciation		(264,467,856	)
Total accumulated losses	$	(2,165,733,808	)

38

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

As of August 31, 2009, the Fund had a net capital loss carryforward of $1,831,201,462, to offset future capital gains to the extent provided by regulations, which will expire according to the following schedule.

AMOUNT		EXPIRATION
$	245,944,739	August 31, 2010
	568,502,378	August 31, 2011
	758,434,573	August 31, 2012

	21,799,070	August 31, 2015
	6,155,549	August 31, 2017

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), capital loss deferrals on wash sales, interest on bonds in default, dividend payable and book amortization of premiums on debt securities.

Permanent differences, primarily due to losses on paydowns, gains on foreign currency and swaps, tax adjustments on debt securities sold by the Fund and an expired capital loss carryforward, resulted in the following reclassifications among the Fund's components of net assets at August 31, 2009:

ACCUMULATED UNDISTRIBUTED NET INVESTMENT INCOME			ACCUMULATED NET REALIZED LOSS		PAID-IN-CAPITAL
$	(2,548,544	)	$	91,751,024	$	(89,202,480	)

11. Accounting Pronouncements

In May 2009, FASB issued Statement of Financial Accounting Standards No. 165, Subsequent Events ("SFAS 165"), which is intended to establish general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS 165 is effective for interim or annual financial periods ending after June 15, 2009. The Fund has adopted the provisions of SFAS 165 as of August 31, 2009. Although the adoption of SFAS 165 did not materially impact its financial position, results of operations or changes in net assets, the Fund is now required to provide additional disclosures, which are included in Note 1.

In June 2009, FASB issued SFAS No. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles — a replacement of FASB Statement No. 162 ("SFAS 168"). SFAS 168 will become the source of authoritative U.S. Generally Accepted Accounting

39

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2009 continued

Principles recognized by the FASB to be applied by nongovernmental entities. Once in effect, all of the Codification's content will carry the same level of authority, effectively superseding FASB Statement No. 162. SFAS 168 is effective for financial statements issued for interim and annual periods ending after September 15, 2009. The Fund does not anticipate that SFAS 168 will have a material impact on its financial statements.

12. Reverse Stock Split

As of the close of business on June 19, 2009, the Fund implemented a 1:10 reverse stock split. This reverse stock split effectively decreased the number of outstanding shares for the Fund. As a result, shareholders' accounts reflect proportionally fewer shares with a higher net asset value per share. While the number of shares declined, neither the Fund's holdings nor the total value of shareholders' investments was affected. Per share data in the financial highlights prior to June 19, 2009, has been adjusted to give effect to this reverse stock split.

13. Subsequent Event

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. As a result, the Investment Adviser expects to propose to the Board of Directors of the Fund that it approve a reorganization of the Fund into a newly organized mutual fund advised by an affiliate of Invesco. It is the Investment Adviser's current expectation that the newly organized Invesco fund would be managed by the same portfolio management team which currently manages the Fund. If approved by the Board, the reorganization would be submitted to the shareholders for their approval.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of
Morgan Stanley High Yield Securities Inc.:

We have audited the accompanying statement of assets and liabilities of Morgan Stanley High Yield Securities Inc. (the "Fund"), including the portfolio of investments, as of August 31, 2009, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2009, by correspondence with the custodian, agent bank and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Morgan Stanley High Yield Securities Inc. as of August 31, 2009, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities that are greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and Board of Trustees in the absence of such designation or identification

APPENDIX A

AUDIT COMMITTEE

AUDIT AND NON-AUDIT SERVICES

PRE-APPROVAL POLICY AND PROCEDURES

OF THE

MORGAN STANLEY RETAIL AND INSTITUTIONAL FUNDS

AS ADOPTED AND AMENDED JULY 23, 2004,(1)

1.Statement of Principles

The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor’s independence from the Fund.

The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee’s administration of the engagement of the independent auditor.  The SEC’s rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid.  Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee (“general pre-approval”); or require the specific pre-approval of the Audit Committee or its delegate (“specific pre-approval”).  The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors.  As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors.  Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee.

The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee.  The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise.  The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee.  The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations.

(1)This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the “Policy”), adopted as of the date above, supersedes and replaces all prior versions that may have been adopted from time to time.

The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities.  It does not delegate the Audit Committee’s responsibilities to pre-approve services performed by the Independent Auditors to management.

The Fund’s Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors’ independence.

2.Delegation

As provided in the Act and the SEC’s rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members.  The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

3.Audit Services

The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee.  Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund’s financial statements.  These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit.  The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items.

In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide.  Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings.

The Audit Committee has pre-approved the Audit services in Appendix B.1.  All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

4.Audit-related Services

Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund’s financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors.  Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC’s rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services.  Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters

not classified as “Audit services”; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR.

The Audit Committee has pre-approved the Audit-related services in Appendix B.2.  All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

5.Tax Services

The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor’s independence, and the SEC has stated that the Independent Auditors may provide such services.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3.  All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

6.All Other Services

The Audit Committee believes, based on the SEC’s rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted.  Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC’s rules on auditor independence.

The Audit Committee has pre-approved the All Other services in Appendix B.4.  Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

7.Pre-Approval Fee Levels or Budgeted Amounts

Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee.  Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee.  The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services.

8.Procedures

All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund’s Chief Financial Officer and must include a detailed description of the services to be

rendered.  The Fund’s Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee.  The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors.  Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund’s Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence.

The Audit Committee has designated the Fund’s Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy.  The Fund’s Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring.  Both the Fund’s Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund’s Chief Financial Officer or any member of management.

9.Additional Requirements

The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor’s independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence.

10.Covered Entities

Covered Entities include the Fund’s investment adviser(s) and any entity controlling, controlled by or under common control with the Fund’s investment adviser(s) that provides ongoing services to the Fund(s).  Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund’s audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund.  This list of Covered Entities would include:

EXHIBIT 12 A

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND SENIOR FINANCIAL OFFICERS
ADOPTED SEPTEMBER 28, 2004, AS AMENDED SEPTEMBER 20, 2005, DECEMBER 1, 2006, JANUARY 1, 2008 , SEPTEMBER 25, 2008 AND APRIL 23, 2009

I.This Code of Ethics (the “Code”) for the investment companies within the Morgan Stanley complex identified in Exhibit A (collectively, “Funds” and each, a “Fund”) applies to each Fund’s Principal Executive Officer, President, Principal Financial Officer and Treasurer (or persons performing similar functions) (“Covered Officers” each of whom are set forth in Exhibit B) for the purpose of promoting:

·honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships.

·full, fair, accurate, timely and understandable disclosure in reports and documents that a company files with, or submits to, the Securities and Exchange Commission (“SEC”) and in other public communications made by the Fund;

·compliance with applicable laws and governmental rules and regulations;

·prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

·accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.  Any question about the application of the Code should be referred to the General Counsel or his/her designee (who is set forth in Exhibit C).

II.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview.  A “conflict of interest” occurs when a Covered Officer’s private interest interferes, or appears to interfere, with the interests of, or his service to, the Fund.  For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940 (“Investment Company Act”) and the Investment Advisers Act of 1940 (“Investment Advisers Act”).  For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as “affiliated persons” (as defined in the Investment Company Act) of the Fund.  The Fund’s and its investment adviser’s compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions.  This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside the parameters of this Code, unless or until the General Counsel determines that any violation of such programs and procedures is also a violation of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts may arise from, or as a result of, the contractual relationship between the Fund and its investment adviser of which the Covered Officers are also officers or employees.  As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund or for the investment adviser, or for both), be involved in establishing policies and implementing decisions that will have different effects on the Fund and its investment adviser.  The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the investment adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Fund.  Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically.  In addition, it is recognized by the Funds’ Boards of Directors/Trustees (“Boards”) that the Covered Officers may also be officers or employees of one or more other investment companies covered by this or other codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act.  The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive.  The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must not:

·use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally (directly or indirectly);

·cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fund; or

·use material non-public knowledge of portfolio transactions made or contemplated for, or actions proposed to be taken by, the Fund to trade

personally or cause others to trade personally in contemplation of the market effect of such transactions.

Each Covered Officer must, at the time of signing this Code, report to the General Counsel all affiliations or significant business relationships outside the Morgan Stanley complex and must update the report annually.

Conflict of interest situations should always be approved by the General Counsel and communicated to the relevant Fund or Fund’s Board.  Any activity or relationship that would present such a conflict for a Covered Officer would likely also present a conflict for the Covered Officer if an immediate member of the Covered Officer’s family living in the same household engages in such an activity or has such a relationship.  Examples of these include:

·service or significant business relationships as a director on the board of any public or private company;

·accepting directly or indirectly, anything of value, including gifts and gratuities in excess of $100 per year from any person or entity with which the Fund has current or prospective business dealings, not including occasional meals or tickets for theatre or sporting events or other similar entertainment; provided it is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

·any ownership interest in, or any consulting or employment relationship with, any of the Fund’s service providers, other than its investment adviser, principal underwriter, or any affiliated person thereof; and

·a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer’s employment, such as compensation or equity ownership.

III.Disclosure and Compliance

·Each Covered Officer should familiarize himself/herself with the disclosure and compliance requirements generally applicable to the Funds;

·each Covered Officer must not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund’s Directors/Trustees and auditors, or to governmental regulators and self-regulatory organizations;

·each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Funds and their investment advisers with the goal of promoting full, fair, accurate,

timely and understandable disclosure in the reports and documents the Funds file with, or submit to, the SEC and in other public communications made by the Funds; and

·it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV.Reporting and Accountability

Each Covered Officer must:

·upon adoption of the Code (thereafter as applicable, upon becoming a Covered Officer), affirm in writing to the Boards that he has received, read and understands the Code;

·annually thereafter affirm to the Boards that he has complied with the requirements of the Code;

·not retaliate against any other Covered Officer, other officer or any employee of the Funds or their affiliated persons for reports of potential violations that are made in good faith; and

·notify the General Counsel promptly if he/she knows or suspects of any violation of this Code.  Failure to do so is itself a violation of this Code.

The General Counsel is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation.  However, any waivers(2) sought by a Covered Officer must be considered by the Board of the relevant Fund or Funds.

The Funds will follow these procedures in investigating and enforcing this Code:

·the General Counsel will take all appropriate action to investigate any potential violations reported to him;

·if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action;

·any matter that the General Counsel believes is a violation will be reported to the relevant Fund’s Audit Committee;

(2)Item 2 of Form N-CSR defines “waiver” as “the approval by the registrant of a material departure from a provision of the code of ethics.”

·if the directors/trustees/managing general partners who are not “interested persons” as defined by the Investment Company Act (the “Independent Directors/Trustees/Managing General Partners”) of the relevant Fund concur that a violation has occurred, they will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to dismiss the Covered Officer or other appropriate disciplinary actions;

·the Independent Directors/Trustees/Managing General Partners of the relevant Fund will be responsible for granting waivers of this Code, as appropriate; and

·any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

V.Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder.  Insofar as other policies or procedures of the Funds, the Funds’ investment advisers, principal underwriters, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code unless any provision of this Code conflicts with any applicable federal or state law, in which case the requirements of such law will govern.  The Funds’ and their investment advisers’ and principal underwriters’ codes of ethics under Rule 17j-1 under the Investment Company Act and Morgan Stanley’s Code of Ethics are separate requirements applying to the Covered Officers and others, and are not part of this Code.

VI.Amendments

Any amendments to this Code, other than amendments to Exhibits A, B or C, must be approved or ratified by a majority vote of the Board of each Fund, including a majority of Independent Directors/Trustees/Managing General Partners.

VII.Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly.  Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Independent Directors/Trustees/Managing General Partners of the relevant Fund or Funds and their counsel, the relevant Fund or Funds and their counsel and the relevant investment adviser and its counsel.

VIII.Internal Use

The Code is intended solely for the internal use by the Funds and does not constitute an admission, by or on behalf of any Fund, as to any fact, circumstance, or legal conclusion

I have read and understand the terms of the above Code.  I recognize the responsibilities and obligations incurred by me as a result of my being subject to the Code.  I hereby agree to abide by the above Code.
