SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE AND BENCHMARK INFORMATION. MARKET CONDITIONS In the early months of the reporting period, the economy continued to show resilience, inflation remained in check and the equity market improved. Together, these factors provided support for the high yield market, helping to keep returns in positive territory despite a declining appetite for corporate credit risk and rising interest rates. In the first quarter of 2006, the high yield market benefited from a rekindled investor interest in adding risk, which was fueled by continued solid economic growth and a briskly rising equity market. The healthy gains in the high yield market came despite declining Treasury prices, tight credit spreads, moderate new issuance and outflows from mutual funds. Against this backdrop, the riskiest segment of the bond market -- securities rated CCC and below -- had the best showing, outperforming higher-quality issues. Although returns dipped in the second quarter, the high yield market still fared better than most other asset classes, including equities. The low positive returns of the high yield market came despite robust new issuance, increased market volatility and lower Treasury prices. Lower-rated bonds continued to outperform their higher-rated counterparts, with CCC-rated securities turning in the best returns. In the last months of the reporting period, high yield prices rebounded nicely as investors appeared confident that good economic growth and loose credit conditions would continue to be positive for high yield credits. High yield bonds again outpaced equities. However, because of their high correlation to Treasuries, which rallied in July, higher-quality fixed-income securities posted better overall returns than lower-rated, high yield bonds. Of note, the Federal Open Market Committee (the "Fed") finally paused in its two-year long series of interest-rate increases, electing not to raise the target federal funds rate at its August meeting. Industry returns varied considerably across individual sectors, many of which were significantly influenced by individual companies. For example, the aerospace sector benefited from a rebound in airline issues, while poor performance of auto-related companies hindered the transportation sector. In the second half of the period, however, transportation and manufacturing were the best performing sectors due to strong gains by the auto industry. In July, the health care sector was hurt by 2 <Page> the announcement that HCA, one of the larger issuers in high yield, had agreed to be bought out in a highly leveraged transaction. PERFORMANCE ANALYSIS Morgan Stanley High Yield Securities Inc. underperformed the Lehman Brothers U.S. Corporate High Yield-2% Issuer Cap Index (the "Index"), the CSFB High Yield Index and the Lipper High Current Yield Bond Funds Index for the 12 months ended August 31, 2006, assuming no deduction of applicable sales charges. In general, the Fund was overweighted versus the Index in the chemicals and food/tobacco sectors, and underweighted in utilities throughout the reporting year which detracted from performance. Early in the period, the Fund was also underweight versus the Index in the transportation sector, which was beneficial to performance given the struggles in the auto industry. From January through August, the Fund had an overweight in transportation companies relative to the Index, which helped performance as the sector rebounded. Strong security selection in the sector, as well as in the utilities sector, also added to performance. On a less positive note, security selection in forest products detracted from performance. Regarding credit risk, the Fund's overall average credit quality was in line with the Index early in the period but its yield-to-maturity was comparatively lower, signifying less relative credit risk. We began reducing the risk in the portfolio in order to take advantage of our belief that high yield prices may move lower and that spreads, which were tighter than historical averages, may widen. We continued this defensive strategy throughout the duration of the reporting period, which tempered the Fund's returns from February through May, but was additive to performance over the last three months of the period when higher-rated bonds outperformed lower-quality issues.

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 D 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 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. + THE MAXIMUM CONTINGENT DEFERRED SALES CHARGE FOR CLASS C IS 1.0% FOR SHARES REDEEMED WITHIN ONE YEAR OF PURCHASE. ++ CLASS D HAS NO SALES CHARGE.

SEE THE FUND'S CURRENT PROSPECTUS FOR COMPLETE DETAILS ON FEES AND SALES CHARGES. ~ ENDING VALUE ASSUMING A COMPLETE REDEMPTION ON AUGUST 31, 2006. 7 <Page> 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 03/01/06 - 08/31/06. 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. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD * ------------- ------------- --------------- 03/01/06 - 03/01/06 08/31/06 08/31/06 ------------- ------------- --------------- CLASS A Actual (2.75% return) $1,000.00 $1,027.50 $6.49 Hypothetical (5% annual return before expenses) $1,000.00 $1,018.80 $6.46 CLASS B Actual (1.91% return) $1,000.00 $1,019.10 $9.01 Hypothetical (5% annual return before expenses) $1,000.00 $1,016.28 $9.00 CLASS C Actual (1.86% return) $1,000.00 $1,018.60 $9.51 Hypothetical (5% annual return before expenses) $1,000.00 $1,015.78 $9.50 CLASS D Actual (2.88% return) $1,000.00 $1,028.80 $5.22 Hypothetical (5% annual return before expenses) $1,000.00 $1,020.06 $5.19 </Table> - ---------- * EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 1.27%, 1.77%, 1.87% AND 1.02% FOR CLASS A, CLASS B, CLASS C AND CLASS D SHARES, RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 184/365 (TO REFLECT THE ONE-HALF YEAR PERIOD). IF THE FUND HAD BORNE ALL OF ITS EXPENSES THAT WERE REIMBURSED OR WAIVED BY THE INVESTMENT ADVISER AND ADMINISTRATOR, THE ANNUALIZED EXPENSE RATIOS WOULD HAVE BEEN 1.36%, 1.86%, 1.96% AND 1.11% FOR CLASS A, CLASS B, CLASS C AND CLASS D SHARES, RESPECTIVELY. 8 <Page> 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 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 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 provided 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 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 November 30, 2005, 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. When a fund underperforms its performance peer group, the Board discusses with the Adviser the causes of the underperformance and, where necessary, specific changes to the fund's investment strategy or investment personnel. The Board concluded that the Fund can reasonably be expected to be competitive with that of its performance peer group based on recent action taken or proposed to be taken by the Adviser with respect to the Fund's investment strategy and/or investment personnel. 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 <Page> 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 management fee rate and total expense ratio were competitive with those 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. 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 float benefits were relatively small and the sales charges and 12b-1 fees were competitive with those of other broker-dealers. 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 primarily in fixed income securities, which do not generate soft dollars. 10 <Page> 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 noted that the Adviser's operations remain profitable, although increased expenses in recent years have reduced the Adviser's profitability. 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. 11 <Page> MORGAN STANLEY HIGH YIELD SECURITIES INC.

NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2006 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 D 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 D 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 D shares, which is paid directly to the Fund, for shares redeemed within thirty days of purchase. 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 exchanges, the last reported sale price or the latest bid price may be used if there were no sales on a particular day; (5) when market quotations are not readily available including circumstances under which Morgan Stanley Investment Advisors Inc. (the "Investment Adviser") determines that the latest sale price, the bid price or the mean between the last reported bid and asked price do not reflect a security's market value, portfolio securities are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Fund's 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 26 <Page> 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; (6) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Directors; and (7) 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. Interest income is accrued daily except where collection is not expected. C. Repurchase Agreements -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated entities managed by the Investment Adviser, may transfer uninvested cash balances into one or more joint repurchase agreement accounts. These balances are invested in one or more repurchase agreements and are collateralized by cash, U.S. Treasury or federal agency obligations. The Fund may also invest directly with institutions in repurchase agreements. The Fund's custodian receives the collateral, which is marked-to-market daily to determine that the value of the collateral does not decrease below the repurchase price plus accrued interest. D. 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. 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 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 27 <Page> 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 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. Federal Income Tax Policy -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Accordingly, no federal income tax provision is required. G. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. H. 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 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. Effective November 18, 2005, the Investment Adviser has agreed to cap the Fund's operating expenses (except for brokerage and 12b-1 fees) for one year by assuming the Fund's "other expenses" and/or waiving the Fund's advisory fees, and the Administrator has agreed to waive the Fund's administrative fees, to the extent such operating expenses on an annualized basis exceed 1.02% of the average daily net assets of the Fund. 28 <Page> 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; (ii) Class B -- up to 0.75% of the average daily net assets of Class B; and (iii) Class C -- up to 0.85% of the average daily net assets of Class C. 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 $59,613,113 at August 31, 2006. 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, 2006, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.25% and 0.83%, respectively. The Distributor has informed the Fund that for the year ended August 31, 2006, it received contingent deferred sales charges from certain redemptions of the Fund's Class A shares, Class B shares and Class C shares of $390, $437,127 and $2,249, respectively and received $23,079 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 cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended August 31, 2006, aggregated $87,641,860 and $220,145,465, respectively. Included in the aforementioned transactions are sales of $25,026,228 with other Morgan Stanley funds, including realized gains of $178,943. 29 <Page> 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 included in Directors' fees and expenses in the Statement of Operations amounted to $16,458. At August 31, 2006, the Fund had an accrued pension liability of $129,232 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 they receive for serving on the Board of Directors. Each eligible Director generally may elect to have their deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Fund. An affiliated company is a company in which the Fund has ownership of at least 5% of the voting securities at any point during the fiscal year. Transactions with such companies during the year ended August 31, 2006 were as follows: <Table> <Caption> REALIZED ISSUER PURCHASES SALES GAIN INCOME VALUE - ------ --------- ---------- ---------- -------- ------- Catalina Restaurant Group (Common Stock) -- $4,232,639 $1,083,999 -- -- Catalina Restaurant Group (Preferred Stock) (units) -- 2,283,061 20,349 $673,821 -- Catalina Restaurant Group (Warrants) -- 460,296 460,296 -- -- Catalina Restaurant Group (escrow) -- -- 159,492(1) -- $ 0 American Restaurant Group Holding, Inc.

Purposes of and Risks Relating to Certain Financial Instruments 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. 30 <Page> 6.

Expense Offset The expense offset represents a reduction of the transfer agent fees and expenses for earnings on cash balances maintained by the Fund. 8. 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. 31 <Page> The tax character of distributions paid was as follows: FOR THE YEAR FOR THE YEAR ENDED ENDED AUGUST 31, 2006 AUGUST 31, 2005 --------------- --------------- Ordinary Income $23,902,815 $35,262,301 =========== =========== As of August 31, 2006, the tax-basis components of accumulated losses were as follows: Undistributed ordinary income $ 1,668,546 Undistributed long-term gains -- --------------- Net accumulated earnings 1,668,546 Capital loss carryforward* (1,987,313,218) Post-October losses (26,120,036) Temporary differences (1,168,118) Net unrealized depreciation (317,242,389) --------------- Total accumulated losses $(2,330,175,215) =============== *As of August 31, 2006, the Fund had a net capital loss carryforward of $1,987,313,218 of which $24,919,181 will expire on August 31, 2007, $69,856,779 will expire on August 31, 2008, $89,299,249 will expire on August 31, 2009, $245,944,739 will expire on August 31, 2010, $568,502,378 will expire on August 31, 2011, $758,434,573 will expire on August 31, 2012, $183,559,922 will expire on August 31, 2013 and $46,796,397 will expire on August 31, 2014 to offset future capital gains to the extent provided by regulations. As of August 31, 2006, 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), interest on bonds in default and book amortization of discounts on debt securities and permanent book/tax differences primarily attributable to tax adjustments on debt securities sold by the Fund and an expired capital loss carryforward. To reflect reclassifications arising from the permanent differences, paid-in-capital was charged $12,603,314, accumulated undistributed net investment income was credited $103,472 and accumulated net realized loss was credited $12,499,842. 9. Legal Matters The Investment Adviser, certain affiliates of the Investment Adviser, certain officers of such affiliates and certain investment companies advised by the Investment Adviser or its affiliates, including the Fund, were named as defendants in a consolidated class action. This consolidated action also named as defendants certain individual Trustees and Directors of the Morgan Stanley funds. The consolidated amended complaint, filed in the United States District Court for the Southern District of New York on April 16, 2004, generally alleged that defendants, including the Fund, violated their statutory disclosure 32 <Page> obligations and fiduciary duties by failing properly to disclose (i) that the Investment Adviser and certain affiliates of the Investment Adviser allegedly offered economic incentives to brokers and others to recommend the funds advised by the Investment Adviser or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Investment Adviser or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their alleged efforts to recommend these funds to investors. The complaint sought, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. On July 2, 2004 defendants moved to dismiss the action. On March 9, 2005, plaintiffs filed a Motion for Leave to File a Supplemental Pleading that would, among other things, expand the allegations and alleged class. On April 14, 2006, the Court granted defendants' motion to dismiss in its entirety, with prejudice. Additionally, plaintiffs' Motion for Leave to File a Supplemental Pleading was denied. The time for plaintiffs to appeal the orders granting defendants' motion to dismiss and denying plaintiffs' motion for supplemental pleading has expired. This case is now concluded. 10. New Accounting Pronouncements In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Fund will adopt FIN 48 during 2007 and the impact to the Fund's financial statements, if any, is currently being assessed. In addition, 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. 33 <Page> MORGAN STANLEY HIGH YIELD SECURITIES INC.

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, 2006, 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, 2006, by correspondence with the custodian. 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, 2006, 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.

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. <Page> 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 <Page> 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 <Page> 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.
