We will provide an overview of the market conditions, and discuss some of the factors that affected performance during the reporting period. In addition, this report includes the Fund's financial statements and a list of Fund investments. Market forecasts provided in this report may not necessarily come to pass. There is no assurance that the Fund will achieve its investment objective. The Fund is subject to market risk, which is the possibility that market values of securities owned by the Fund will decline and, therefore, the value of the Fund's shares may be less than what you paid for them. Accordingly, you can lose money investing in this Fund. FUND REPORT For the six-months ended March 31, 2005 MARKET CONDITIONS The six-month period under review began amid perceived softness in the economy in the minds of investors, brought on by lower-than-expected payroll gains. The Federal Open Market Committee reaffirmed its pledge to raise the federal funds target rate at a measured pace and did so incrementally at each of its meetings, raising the target rate 100 basis points, to 2.75 percent from 1.75 percent by the end of the period. The economic climate for corporate bonds during the period was generally positive, fueled by investors' continuing thirst for yield. Nonetheless, corporate bond yield spreads widened during the first quarter of 2005, with most of the damage coming in the auto sector. News that General Motors (GM) had lowered its earnings guidance for the remainder of 2005 brought on elevated fears that the automaker might lose its investment-grade credit rating. Yield spreads on GM bonds soared, with the company's longer maturity issues eventually surpassing the 500 basis-point level relative to equivalent treasuries. Other auto and auto-related issuers' yield spreads also widened, albeit not by the same magnitude as GM's spreads. PERFORMANCE ANALYSIS For the six-month period ended March 31, 2005, the net asset value (NAV) of Morgan Stanley Income Securities Inc. (ICB) decreased from $17.59 to $17.27 per share. Based on this change plus the reinvestment of dividends totaling $0.4875 per share, the Fund's total NAV return was 1.19 percent. ICB's value on the New York Stock Exchange (NYSE) decreased from $16.04 to $15.39 per share during the same period. Based on this change plus the reinvestment of dividends, ICB's total market return was -1.11 percent. ICB's share price was trading at a 10.89 percent discount to its NAV on March 31, 2005. Past performance is no guarantee of future results. Monthly dividends for the second quarter of 2005 declared in March remained unchanged at $0.08125 per share to reflect the Fund's current and projected earnings level. Within the corporate sector, the Fund benefited from its emphasis on insurance company debt and strong security selection in the paper and energy sectors. Paper, gaming/lodging, and energy remain the focus of the Fund's medium-quality strategy. Within the high-quality segment of the portfolio, the Fund remained focused on the insurance industry. We kept the Fund's overall interest-rate exposure trimmed during the period. This posture helped the Fund as interest rates rose across the short- and intermediate-portions of the yield curve. As interest rates declined during the initial phase of the review period, however, this position hampered the Fund's performance. The Fund's procedure for reinvestment of all dividends and distributions in common shares is through purchases in the open market. This method helps support the market value of the Fund's shares. In addition, we would like to remind you that the Directors have approved a procedure whereby the Fund may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase. - ---------------------------------------------------- There is no guarantee that any sectors mentioned will continue to perform well or be held by the Fund in the future. 2 <Table> <Caption> PORTFOLIO COMPOSITION* Corporate Bonds 76.3% U.S. Government Obligations 13.0 Asset-Backed Securities 4.1 Foreign Government Obligations 3.4 Short-Term Investments 3.2 </Table> <Table> <Caption> LONG-TERM CREDIT ANALYSIS AAA 20.5% AA 1.9 A 14.1 BBB 50.1 BB 11.7 B 1.7 </Table> Data as of March 31, 2005.

NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 (UNAUDITED) 1. Organization and Accounting Policies Morgan Stanley Income Securities Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The Fund's primary investment objective is to provide as high a level of current income as is consistent with prudent investment and, as a secondary objective, capital appreciation. The Fund commenced operations on April 6, 1973. The following is a summary of significant accounting policies: A. Valuation of Investments -- (1) certain portfolio securities may be valued by an outside pricing service approved by the Fund's Directors (2) 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; (3) futures are valued at the latest price published by the commodities exchange on which they trade; (4) when market quotations are not readily available or Morgan Stanley Investment Advisors Inc. (the "Investment Adviser") determines that the market quotations are not reflective of 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; and (5) 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. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily. 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. 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 17 Morgan Stanley Income Securities Inc. NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 (UNAUDITED) continued entering into such a contract, the Fund is required to pledge to the broker cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as variation margin are recorded by the Fund as unrealized gains and losses. Upon closing of the contract, the Fund realizes a gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. E. 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. F. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. G. 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 Effective November 1, 2004, pursuant to an Investment Advisory Agreement, the Fund pays an advisory fee, accrued weekly and payable monthly, by applying the following annual rates to the net assets of the Fund determined at the close of each business week: 0.42% to the portion of weekly net assets not exceeding $500 million and 0.35% to the portion of weekly net assets exceeding $500 million. Effective November 1, 2004, 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 weekly and payable monthly, by applying the annual rate of 0.08% to the Fund's weekly net assets. Prior to November 1, 2004, the Fund had retained the Investment Adviser to provide administrative services and to manage the investment of the Fund's assets pursuant to an investment management agreement pursuant to which the Fund paid the Investment Adviser a monthly management fee accrued weekly and payable monthly, by applying the following annual rate of 0.50% to the Fund's weekly net assets. 18 Morgan Stanley Income Securities Inc. NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 (UNAUDITED) continued 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales/prepayments of portfolio securities, excluding short-term investments, for the six months ended March 31, 2005 aggregated $44,131,427 and $50,413,742, respectively. Included in the aforementioned are purchases of U.S. Government securities of $21,676,511. Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator, is the Fund's transfer agent. At March 31, 2005, the Fund had transfer agent fees and expenses payable of approximately $1,700. 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. Aggregate pension costs for the six months ended March 31, 2005 included in Directors' fees and expenses in the Statement of Operations amounted to $3,744. At March 31, 2005, the Fund had an accrued pension liability of $61,782 which is included in accrued expenses in the Statement of Assets and Liabilities. On December 2, 2003, 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. 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 receives for serving on the Board of Directors. Each eligible Director generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. 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. 4. Dividends On March 29, 2005, the Fund declared the following dividends from net investment income: <Table> <Caption> AMOUNT RECORD PAYABLE PER SHARE DATE DATE --------- ------------ ------------- April 8, April 22, $0.08125 2005 2005 $0.08125 May 6, 2005 May 20, 2005 $0.08125 June 3, 2005 June 17, 2005 </Table> 19 Morgan Stanley Income Securities Inc.

Purpose of Risks Relating to Certain Financial Instruments To hedge against adverse interest rate and market risks, the Fund may enter into interest rate futures contracts ("future contracts"). These futures contracts involve element of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the value of underlying securities. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts. 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. As of September 30, 2004 the Fund had a net capital loss carryforward of $20,980,110 of which $1,742,631 will expire on September 30, 2009, $9,696,127 will expire on September 30, 2010 20 Morgan Stanley Income Securities Inc. NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 (UNAUDITED) continued and $9,541,352 will expire on September 30, 2011 to offset future capital gains to the extent provided by regulations. As of September 30, 2004, the Fund had temporary book/tax differences primarily attributable to book amortization of premiums on debt securities and mark-to-market of open futures contracts. 21 Morgan Stanley Income Securities Inc.

While the price of the Fund's shares is quoted in U.S. dollars, the Fund generally converts U.S. dollars to a foreign market's local currency to purchase a security in that market. If the value of the local currency falls relative to the U.S. dollar, the U.S. dollar value of the foreign security will decrease. This is true even if the foreign security's local price remains unchanged. The fund may invest up to 20% of its assets in U.S. dollar denominated high yield securities. High yield securities are commonly known as "junk bonds" and are likely to be more sensitive to adverse economic changes or individual corporate developments than higher rated securities. During an economic downturn or substantial period of rising interest rates, junk bond issuers, and in particular, highly leveraged issuers, may experience financial stress that would adversely affect their ability to service their principal and interest payment obligations, meet their projected business goals, or obtain additional financing, all of which may result in increased volatility of market prices of high yield securities and a corresponding volatility in the Fund's net asset value. 23 DIRECTORS Michael Bozic Charles A.
