Preferred Income Strategies Fund, Inc. Preferred and Corporate Income Strategies Fund, Inc. Preferred Income Strategies Fund, Inc. Announcement to Shareholders On February 15, 2006, BlackRock, Inc. ("BlackRock") and Merrill Lynch & Co., Inc. ("Merrill Lynch") entered into an agreement to contribute Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. and certain affiliates (including Fund Asset Management, L.P. and Merrill Lynch Investment Managers International Limited), to BlackRock to create a new independent company that will be one of the world's largest asset management firms with over $1 trillion in assets under management (based on combined assets under management as of March 31, 2006). The transaction is expected to close in the third quarter of 2006, at which time the new company will operate under the BlackRock name. The Funds' Board of Directors has approved a new investment advisory agreement with BlackRock Advisors, Inc. or its successor ("BlackRock Advisors") on substantially the same terms and for the same advisory fee as the current investment advisory agreement with the Investment Adviser. If the new agreement is approved by the Funds' shareholders, BlackRock Advisors is expected to become the Funds' investment adviser upon the closing of the transaction between Merrill Lynch and BlackRock. The Benefits and Risks of Leveraging The Funds utilize leverage through the issuance of Preferred Stock. The concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest or dividend rates on the Preferred Stock, which normally will be lower than the income earned by each Fund on its longer-term portfolio investments. To the extent that the total assets of each Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, each Fund's Common Stock shareholders will be the beneficiaries of the incremental yield. Leverage creates risks for holders of Common Stock including the likelihood of greater net asset value and market price volatility. In addition, there is the risk that fluctuations in the dividend rates on any Preferred Stock may reduce the Common Stock's yield and negatively impact its net asset value and market price. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, each Fund's net income will be greater than if leverage had not been used. Conversely, if the income from the securities purchased is not sufficient to cover the cost of leverage, each Fund's net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Stock shareholders will be reduced.

On February 15, 2006, Merrill Lynch announced plans to combine the firm's investment advisory business, including MLIM, with another highly regarded investment manager -- BlackRock, Inc. ("BlackRock"). We believe this merger of asset management strength will benefit our investors. MLIM is a leading investment management organization with over $576 billion in assets under management globally and 2,757 employees in 17 countries. It offers over 100 investment strategies in vehicles ranging from mutual funds to institutional portfolios. BlackRock is one of the largest publicly traded investment management firms in the United States with $463.1 billion in assets under management and 1,839 employees. It manages assets on behalf of institutional and individual investors worldwide through a variety of equity, fixed income, liquidity and alternative investment products. At the completion of the transaction, which is expected in the third quarter of this year, the resultant firm will be a top-10 investment manager worldwide with over $1 trillion in assets under management.* The combined company will provide a wider selection of high-quality investment solutions across a range of asset classes and investment styles. MLIM and BlackRock possess complementary capabilities that together create a well-rounded organization uniting some of the finest money managers in the industry. At the same time, the firms share similar values and beliefs -- they are focused on delivering excellence on behalf of clients, and both make investment performance their single most important mission. In short, the merger only reinforces our commitment to shareholders. Most of MLIM's investment products -- including mutual funds, separately managed accounts, annuities and variable insurance funds -- eventually will carry the "BlackRock" name. As a shareholder in one or more MLIM-advised mutual funds, you will receive a proxy package in the coming weeks in connection with this transaction. After you receive this information, should you have any questions or concerns, do not hesitate to contact your financial advisor. As always, we thank you for entrusting us with your investment assets, and we look forward to continuing to serve your investment needs with even greater strength and scale as the new BlackRock. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Chief Investment Officer Merrill Lynch Investment Managers * $1.039 trillion in assets under management as of March 31, 2006. Data, including assets under management, are as of March 31, 2006. SEMI-ANNUAL REPORTS APRIL 30, 2006 3 A Discussion With Your Funds' Portfolio Managers The Funds outperformed their benchmark for the six-month period, benefiting from their relatively long spread durations and our use of hedging strategies, which we employed in an effort to reduce the negative effects of rising interest rates. Describe the market and economic environment during the period. The yield curve did not change significantly during the past six months, remaining relatively flat. The spread between two-year and 10-year U.S. Treasury notes was 20 basis points (.20%) at April 30, 2006, just three basis points more than six months ago. The yield on the two-year note rose from 4.40% at October 31, 2005, to 4.87% at period-end, while the yield on the 10-year note rose from 4.57% to 5.07% over the same period. The Federal Reserve Board (the Fed) increased short-term interest rates in four increments of .25% during the period, pushing the target federal funds rate to 4.75% at April 30, 2006. Shortly after the end of the period, the Fed increased short-term interest rates by another .25%, bringing the target rate to 5%. Record-high oil prices and strong gross domestic product (GDP) growth continued to stoke fears of increased inflation. GDP expanded at an estimated annualized rate of 4.8% in the first quarter of 2006, up significantly from the 1.7% and 3.5% annualized growth rates in the fourth quarter and full year 2005, respectively. Although core inflation remained moderate during the period, energy prices were volatile, falling sharply in the fourth quarter of 2005, then climbing significantly during the first quarter of 2006. How did the Funds perform during the period? For the six-month period ended April 30, 2006, the Common Stock of Merrill Lynch Preferred Income Strategies Fund, Inc. had net annualized yields of 7.62% and 8.68%, based on a period-end per share net asset value of $21.67 and a per share market price of $19.02, respectively, and $.819 per share income dividends. For the same period, the total investment return on the Fund's Common Stock was +1.57%, based on a change in per share net asset value from $22.26 to $21.67, and assuming reinvestment of all distributions. The Common Stock of Merrill Lynch Preferred and Corporate Income Strategies Fund, Inc. had net annualized yields of 7.87% and 8.64% during the past six months, based on a period-end per share net asset value of $21.87 and a per share market price of $19.91, respectively, and $.853 per share income dividends. The total investment return on the Fund's Common Stock was +2.11% for the six-month period, based on a change in per share net asset value from $22.36 to $21.87, and assuming reinvestment of all distributions. For the same period, the Funds' benchmark, the Merrill Lynch Preferred Stock Fixed Rate Index, returned +.86%, while the broader-market Merrill Lynch U.S. Corporate Master Index and the Merrill Lynch U.S. Treasury/Agency Master Index returned +.04% and +.15%, respectively. For a description of the Funds' total investment returns based on a change in the per share market value of the Funds' Common Stock (as measured by the trading price of the Funds' shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section of this report. As closed-end funds, the Funds' shares may trade in the secondary market at a premium or discount to the Funds' net asset values. As a result, total investment returns based on changes in the market value of the Funds' Common Stock can vary significantly from total investment returns based on changes in the Funds' net asset values. What factors most influenced the Funds' performance? The credit markets were strong during the period as yield spreads tightened versus Treasury issues. In addition, long-duration corporate bonds outperformed their short-duration counterparts. Therefore, the Funds' overweight positions in longer-duration credits helped to drive their outperformance of the benchmark. The Funds' long spread durations relative to the benchmark also had a positive effect on performance. Spread duration is a measurement of the effect of a 100 basis point increase or reduction in the yield spread of a fixed income security versus U.S. Treasury issues of comparable maturities. In addition, the Funds' performance for the period benefited considerably from our use of net asset value hedges to shorten the portfolios' durations in an effort to reduce the risk of loss in value associated with rising interest rates. We maintained our view that the Fed would continue to raise short-term interest rates gradually, forcing long-term rates higher. The portfolios' underweight positions in short-term callable trust-preferred securities (TruPS), which performed well during the period, detracted somewhat from performance. TruPS are fixed income securities that have characteristics 4 SEMI-ANNUAL REPORTS APRIL 30, 2006 of both stocks and bonds. They have early redemption features, make quarterly fixed interest payments and mature at face value. A company creates TruPS by establishing a trust and issuing debt to the new entity. The company may realize significant federal income tax benefits because the interest paid to the trust is tax deductible. What changes were made to the portfolios during the period? We reduced the portfolios' durations -- which already were shorter than that of their benchmark -- by approximately five years. However, we maintained the Funds' relatively long spread durations. We also continued to trim the Funds' exposure to the banking sector as the yield curve remained relatively flat. Banks earn profits on the spreads between the interest rates they pay to depositors and the rates they charge for loans. Therefore, a flat or narrow yield curve squeezes their profit margins. In addition, we trimmed our holdings in dividends received deduction (DRD) preferred securities, which pay dividends that qualify for the lower maximum federal income tax rate of 15%. (Dividends earned from other types of preferred securities are taxed at an investor's marginal income tax rate, which can be as high as 33%.) Under the DRD provision of the federal tax code, eligible U.S. corporations that receive qualified dividends from other U.S. corporations may deduct 70% of the total U.S. corporate dividends received from their federal taxable income. DRDs offer lower nominal yields than taxable securities of comparable maturities because of their tax advantages. Consequently, we reduced our exposure to these issues in an effort to increase the gross yields of the Funds. How would you characterize the Funds' positioning at the close of the period? We continued to position the Funds in an effort to mitigate the decline in their net asset values resulting from the negative effects of rising interest rates. The preferred stock market has significant exposure to securities issued by financial companies. Therefore, we retained the Funds' sizeable allocations to the financial sector, although the portfolios are underweight relative to the benchmark in these securities. Our largest absolute weightings at the end of the period were in banking and insurance issues, which comprised approximately 47% and 39% of the net assets of Preferred Income Strategies Fund and Preferred and Corporate Income Strategies Fund, respectively. The portfolios are well diversified among issuers, and we intend to maintain this diversification. At April 30, 2006, Preferred Income Strategies Fund and Preferred and Corporate Income Strategies Fund each had a leveraged position of approximately 37%. (For a more complete explanation of the benefits and risks of leveraging, see page 2 of this report to shareholders.) Also at period-end, each Fund carried an average credit rating of Baa1 from Moody's Investors Service, unchanged from the rating at October 31, 2005.

Significant Accounting Policies: Preferred and Corporate Income Strategies Fund, Inc. and Preferred Income Strategies Fund, Inc. (the "Funds" or individually as the "Fund") are registered under the Investment Company Act of 1940, as amended, as diversified, closed-end management investment companies. The Funds' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Funds' Common Stock shares are listed on the New York Stock Exchange ("NYSE") under the symbol PSW for Preferred and Corporate Income Strategies Fund, Inc. and PSY for Preferred Income Strategies Fund, Inc. The following is a summary of significant accounting policies followed by the Funds. (a) Valuation of investments -- Debt securities are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Funds under the general direction of the Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Funds. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sales price in the case of exchange-traded options. In the case of options traded in the OTC market, valuation is the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by each Fund from a pricing service or counterparty. Short-term investments with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value, under which method the investment is valued at cost and any premium or discount is amortized on a straight line basis to maturity. Valuation of other short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Repurchase agreements are valued at cost plus accrued interest. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Funds. Equity securities that are held by the Funds, which are traded on stock exchanges or the Nasdaq National Market, are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Directors of the Funds. Long positions traded in the OTC market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price obtained from one or more dealers or pricing services approved by the Board of Directors of the Funds. Short positions traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Generally, trading in foreign securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation in each of the Fund's net asset value. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Fund's Board of Directors or by the Investment Adviser using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) Derivative financial instruments -- Each Fund may engage in various portfolio investment strategies both to increase the return of each Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. 22 SEMI-ANNUAL REPORTS APRIL 30, 2006 Notes to Financial Statements (continued) o Options -- Each Fund may write and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. o Financial futures contracts -- Each Fund may purchase or sell financial futures contracts and options on such futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. 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 value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized 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. o Swaps -- Each Fund may enter into swap agreements, which are over-the-counter contracts in which the Fund and a counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. (c) Income taxes -- It is each 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. Therefore, no federal income tax provision is required. (d) Security transactions and investment income -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The Funds amortize all premiums and discounts on debt securities. (e) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (f) Securities lending -- Each Fund may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Fund may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Fund could experience delays and costs in gaining access to the collateral. The Fund also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral.

Investment Advisory Agreement and Transactions with Affiliates: Each Fund has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM").

This is not a prospectus. The Funds leverage their Common Stock to provide Common Stock shareholders with potentially higher rates of return.
