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

Market conditions were challenging for the high-yield market throughout most of the 12-month reporting period as the credit crisis and concerns about the economy kept volatility high and led investors to favor less risky assets. Although the pace of economic growth rose to 3.3 percent in the second quarter of 2008, after measuring just 0.9 percent in the first quarter and –0.2 percent in the last quarter of 2007, the overall economic picture remained weak. Job numbers weakened and the housing market remained in the doldrums. Accelerating food and energy prices have taken a toll on consumers as well, causing confidence to dwindle and promptin g concerns about inflation. These factors, coupled with ongoing writedowns by several financial institutions and restricted credit and liquidity, weighed heavily on investor sentiment.

The Federal Reserve (the "Fed") took several steps to help ease the pressure on the market, including a long series of reductions in the target federal funds rate, the last of which took place in April when the rate was cut to 2.0 percent. Although the slowing economy was still a concern, rising inflationary pressures prompted the Fed to maintain interest rates thereafter. The Fed's intervention briefly calmed the markets and resulted in an upsurge in high yield performance in April and May, but following the announcement of additional financial sector writedowns in June and growing recession fears, the market retreated again as high yield spreads moved wider. At the end of August, high yield spreads stood at 829 basis points over Treasuries, significantly wider than historical long-term averages. As a result, high yield bonds underperformed Treasury securities, though they still outpaced equities for the reporting year. As woul d be expected in this environment, higher-quality high yield bonds outperformed lower-quality issues. With regard to sectors, the wireless communications, healthcare and environmental sectors were the top performers in the high yield market, while finance companies, gaming and automotive turned in the worst performance. New issue volume slowed considerably, measuring approximately $50 billion in the first eight months of 2008 — only 40 percent of the volume for the same period last year.

Performance Analysis

All share classes of Morgan Stanley High Yield Securities Inc. outperformed the Lehman Brothers U.S. Corporate High Yield-2% Issuer Cap Index and the Lipper High

2

Current Yield Bond Funds Index for the 12 months ended August 31, 2008, assuming no deduction of applicable sales charges.

The Fund's defensive credit quality positioning was a major contributor to performance for the period. We maintained a higher overall credit quality within the portfolio than that of the Lehman Brothers U.S. Corporate High Yield-2% Issuer Cap Index for most of the reporting period. This positioning was beneficial as the uncertain environment led to a flight to quality that helped higher-rated securities outpace those with lower credit ratings. As high yield spreads moved to levels considerably wider than long-term averages late in the period, we began to increase the Fund's credit exposure to a more neutral position.

An overweight allocation and strong security selection in healthcare, the second best performing sector for the period, utilities, and energy were additive to returns. An underweight exposure to companies in the homebuilding industry was also beneficial as the housing slump has dampened its performance.

The Fund's holdings in mortgage securities, however, hindered performance somewhat. The Fund's exposure to the sector is relatively small, but given the ongoing decline in mortgage securities in the wake of the subprime market meltdown and the fact that these securities are not included in the Lehman Brothers U.S. Corporate High Yield-2% Issuer Cap Index, this position detracted from relative performance.

As of the end of the reporting period, the Fund's major sector overweights relative to the Lehman Brothers U.S. Corporate High Yield-2% Issuer Cap Index were in the healthcare, chemicals, and utility sectors. The Fund's major sector underweights relative to the Index were in building products/home builders, manufacturing, and aerospace/defense.

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 ("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 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. Securities rated below Baa or BBB are commonly known as "junkbonds." 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/msim 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.

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 (formerly Class D) has no sales charge.

(1)  The Lehman Brothers U.S. Corporate High Yield - 2% Issuer Cap Index is the 2% Issuer Cap component of the Lehman Brothers 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 03/01/08 – 08/31/08.

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@
	03/01/08		08/31/08		03/01/08 – 08/31/08

Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,016.29	$	8.92

Hypothetical (5% annual return before expenses)	$	1,000.00	$	1,017.55	$	7.66

  @  Expenses are equal to the Fund's annualized expense ratios of 1.76%, 2.26%, 2.36% and 1.51% for Class A, Class B, Class C and Class I shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

  @@  Formerly Class D shares. Renamed Class I shares effective March 31, 2008.

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 Adviser (as defined herein) under the advisory agreement, including portfolio management, investment research and equity and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Adviser under the administration agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Adviser's expense. (The 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 provided by non-affiliated advisers as reported to the Bo ard 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 Relative to Comparable Funds Managed by Other Advisers

On a regular basis, the Board reviews the performance of all funds in the Morgan Stanley Fund Complex, including the Fund, compared to their peers, paying specific attention to the underperforming funds. In addition, the Board specifically reviewed the Fund's performance for the one-, three- and five-year periods ended December 31, 2007, as shown in a report provided by Lipper (the "Lipper Report"), compared to the performance of comparable funds selected by Lipper (the "performance peer group"). The Board also discussed with the Adviser the performance goals and the actual results achieved in managing the Fund. The Board concluded that the Fund's performance was competitive with that of its performance peer group.

Fees Relative to Other Proprietary Funds Managed by the Adviser with Comparable Investment Strategies

The Board reviewed the advisory and administrative fee (together, the "management fee") rate paid by the Fund under the Management Agreement. The Board noted that the management fee rate was comparable to the management fee rates charged by the Adviser to other proprietary funds it manages with investment strategies comparable to those of the Fund taking into account the scope of the services provided.

9

Fees and Expenses Relative to Comparable Funds Managed by Other Advisers

The Board reviewed the management fee rate and total expense ratio of the Fund as compared to the average management fee rate and average total expense ratio for funds, selected by Lipper (the "expense peer group"), managed by other advisers with investment strategies comparable to those of the Fund, as shown in the Lipper Report. The Board concluded that the Fund's total expense ratio, although higher than the peer group average, was acceptable as the management fee rate was competitive with that of its expense peer group.

Breakpoints and Economies of Scale

The Board reviewed the structure of the Fund's management fee schedule under the Management Agreement and noted that it includes breakpoints. The Board also reviewed the level of the Fund's management fee and noted that the fee, as a percentage of the Fund's net assets, would decrease as net assets increase because the management fee includes breakpoints. The Board concluded that the Fund's management fee would reflect economies of scale as assets increase.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and 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. Based on its review of the information it received, the Board concluded that the profits earned by the Adviser and affiliates were not excessive in light of the advisory, administrative and other services provided to the Fund.

Fall-Out Benefits

The Board considered so-called "fall-out benefits" derived by the Adviser and affiliates from their relationship with the Fund and the Morgan Stanley Fund Complex, such as sales charges on sales of Class A shares and "float" benefits derived from handling of checks for purchases and sales of Fund shares, through a broker-dealer affiliate of the Adviser and "soft dollar" benefits (discussed in the next section). The Board also considered that, from time to time, the Adviser may, directly or indirectly, effect trades on behalf of certain Morgan Stanley Funds through various electronic communications networks or other alternative trading systems in which the Adviser's affiliates have ownership interests and/or board seats. The Board also considered that a broker-dealer affiliate of the Adviser receives from the Fund 12b-1 fees for distribution and shareholder services. The Board concluded that the fall-out benefits were relatively small and the sales charges and 12b-1 fees were competitive with those of other broker-dealers.

10

Soft Dollar Benefits

The Board considered whether the Adviser realizes any benefits from commissions paid to brokers who execute securities transactions for the Fund ("soft dollars"). The Board noted that the Fund invests only in fixed income securities, which do not generate soft dollars.

Adviser Financially Sound and Financially Capable of Meeting the Fund's Needs

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement.

Historical Relationship Between the Fund and the Adviser

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 it is beneficial for the Fund to continue its relationship with the Adviser.

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.

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. Effective March 31, 2008, Class D shares were renamed Class I shares.

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 is 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 asked 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 asked 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 asked 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 e xchanges, 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 asked price do not reflect a security's market value, portfolio securities are valued at their fair value as

31

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

determined in good faith under procedures established by and under the general supervision of the 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, includi ng the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close 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.

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 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 Contracts — 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 or 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 investment securities, other assets and liabilities and forward foreign currency contracts ("forward contracts") are

32

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

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 gain/loss on foreign exchange transactions. Pursuant to U.S. federal income tax regulations, certain foreign exchange gains/losses included in realized and unrealized gain/loss 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 the appropriate exchange rates. The resultant unrealized exchange gains and losses are recorded as unrealized foreign currency gain or loss. The Fund records realiz ed 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. Credit Default Swaps — A credit default swap is an agreement between two parties to exchange the credit risk of an issuer. The Fund may purchase credit protection on the referenced obligation of the credit default swap ("Buy Contract"), or provide credit protection on the referenced obligation of the credit default swap ("Sale Contract"). 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 or a failure to pay outstanding obligations 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. If a credit event occurs, the seller pays to the buyer an agreed amount which approximates the notional amount of the swap contract as di sclosed in the table following the Portfolio of Investments. During the term of the swap agreement, the Fund receives or pays periodic fixed payments from or to the respective counterparty calculated at the agreed upon interest rate applied to the notional amount. These periodic payments are accrued daily and recorded as realized gains or losses in the Statement of Operations. In addition, upon termination of the swap contract, gains and losses are also realized. Any upfront payment received or paid by the Fund is recorded as assets/liabilities on the Fund's books. The Fund may pay or receive cash to collateralize credit default swap contracts. This cash collateral is recorded as assets/liabilities on the Fund's books. Any cash received may be invested in Morgan Stanley Institutional Liquidity Fund.

G. Interest Rate Swaps — Interest rate swaps involve the exchange of commitments to pay and receive interest based on a notional principal amount. Net periodic interest payments to be received or paid are accrued daily and are recorded as realized gains or losses in the Statement of Operations. The Fund may pay or receive cash to collateralize interest rate swap contracts. This cash collateral is recorded as assets/liabilities on the Fund's books. Any cash received may be invested in Morgan Stanley Institutional Liquidity Funds.

33

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

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, 2008 are $37,270,440 and $38,874,129, respectively. The Fund has the right under the lending agreement to recover the securities from the borrower.

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 adopted the provisions of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on February 28, 2008. FIN 48 sets forth a minimum threshold for fina ncial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not result in any 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, 2008, 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.

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

2. Investment Advisory/ Administration Agreements

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

34

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

determined at the close of each business day: 0.42% to the portion of the daily net assets not exceeding $500 million; 0.345% to the portion of the daily net assets exceeding $500 million but not exceeding $750 million; 0.295% to the portion of the daily net assets exceeding $750 million but not exceeding $1 billion; 0.27% to the portion of the daily net assets exceeding $1 billion but not exceeding $2 billion; 0.245% to the portion of the daily net assets exceeding $2 billion but not exceeding $3 billion; and 0.22% to the portion of the daily net assets exceeding $3 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.

3. 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 $64,705,065 at August 31, 2008.

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, 2008, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.25% and 0.85%, respectively.

35

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

The Distributor has informed the Fund that for the year ended August 31, 2008, it received contingent deferred sales charges from certain redemptions of the Fund's Class A shares, Class B shares and Class C shares of $148, $120,229 and $1,130, respectively and received $13,762 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.

4. Security Transactions and Transactions with Affiliates

The Fund invests in Morgan Stanley Institutional Liquidity 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 Money Market Portfolio — Institutional Class with respect to assets invested by the Fund in Morgan Stanley Institutional Liquidity Money Market Portfolio — Institutional Class. For the year ended August 31, 2008, advisory fees paid were reduced by $4,129 relating to the Fund's investment in Morgan Stanley Institutional Liquidity Money Market Portfolio — Institutional Class. Income distributions earned by the Fund are recorded as dividends from affiliate in the Statement of Operations and totaled $154,216 for the year ended August 31, 2008. During the year ended August 31, 2008, cost of purchases and sales of investments in Morgan Stanley Institutional Liquidity Money Market Portfolio — Institutional Class aggregated $77,632,995 and $81,455,054, respectively.

The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended August 31, 2008, aggregated $49,151,801 and $81,497,877, 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, 2008, included in Directors' fees and expenses in the Statement of Operations amounted to $15,065. At August 31, 2008, the Fund had an accrued pension liability of $120,004 which is included in accrued expenses 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

36

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

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.

5. Purposes of and Risks Relating to Certain Financial Instruments

The Fund may purchase 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.

To hedge against adverse interest rates, the Fund may purchase and sell interest rate futures contracts ("futures contracts").

Forward and 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 underlying securities or currencies. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

The Fund may enter into interest rate 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. Interest rate 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 a 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.

The Fund may invest in mortgage securities. These are fixed income securities that derive their value from or represent interests in a pool of mortgages or mortgage securities. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of a mortgage-backed security and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include sub-prime mortgages. Sub-prime mortgages refer to loans

37

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their mortgages.

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.

7. 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, 2008			FOR THE YEAR ENDED AUGUST 31, 2007
Ordinary income	$	12,305,934		$	15,946,517
As of August 31, 2008, the tax-basis components of accumulated losses were as follows:
Undistributed ordinary income	$	2,929,643
Undistributed long-term gains		—
Net accumulated earnings		2,929,643
Capital loss carryforward*		(1,914,345,162	)
Post-October losses		(9,306	)
Temporary differences		(1,368,842	)
Net unrealized depreciation		(330,623,258	)
Total accumulated losses	$	(2,243,416,925	)

*During the year ended August 31, 2008, the Fund utilized $72,054 of its net capital loss carryforward. As of August 31, 2008, the Fund had a net capital loss carryforward of $1,914,345,162, to offset future capital gains to the extent provided by regulations, which will expire according to the following schedule.

AMOUNT		EXPIRATION
$	89,299,249	August 31, 2009
	245,944,739	August 31, 2010
	568,502,378	August 31, 2011

	46,805,231	August 31, 2014
	21,799,070	August 31, 2015

As of August 31, 2008, the Fund had temporary book/tax differences primarily attributable to post-October losses (foreign currency losses incurred after October 31 within the taxable year which are

39

Morgan Stanley High Yield Securities Inc.

Notes to Financial Statements  nAugust 31, 2008 continued

deemed to arise on the first business day of the Fund's next taxable year), interest on bonds in default and book amortization of discounts on debt securities.

Permanent differences, primarily due to losses on paydowns and foreign currency, gains on 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, 2008:

ACCUMULATED UNDISTRIBUTED NET INVESTMENT INCOME		ACCUMULATED NET REALIZED LOSS		PAID-IN-CAPITAL
$	1,141,063	$	68,643,919	$	(69,784,982	)

8. 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.

9. Accounting Pronouncement

In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

On March 19, 2008, FASB released Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB statements No. 133 ("SFAS 161"). SFAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of SFAS 161 is required for fiscal years beginning after November 15, 2008 and interim periods within those fiscal years. At this time, management is evaluating the implications of SFAS 161 and its impact on the financial statements has not yet been determined.

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, 2008, and the related statements of operations for the year then ended and 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, 2008, by correspondence with the custodian 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, 2008, 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.

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:
