Diversified Income Strategies Portfolio, Inc.

The Benefits and Risks of Leveraging

Diversified Income Strategies Portfolio, Inc. has the ability to utilize
leverage through borrowings or issuance of short-term debt securities or shares
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
rates, which normally will be lower than the income earned by the Fund on its
longer-term portfolio investments. To the extent that the total assets of the
Fund (including the assets obtained from leverage) are invested in
higher-yielding portfolio investments, the 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 interest rates on borrowings (or in the dividend rates
on any Preferred Stock, if the Fund were to issue 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, the 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, the 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.

A Letter From the President

Dear Shareholder

Financial markets broadly posted positive returns over the most recent reporting
period, with international equities providing some of the most impressive
results.

The U.S. economy has continued to show resilience in the face of the Federal
Reserve Board's (the Fed) continued interest rate hikes and, more recently,
higher oil prices. The Fed's measured tightening program recently brought the
federal funds rate to 2.75% en route to a more "neutral" short-term interest
rate target (relative to inflation). Since the U.S. presidential election,
progress has been monitored on many fronts in Washington, although concerns
remain about the structural problems of debt and deficits, as reflected by a
significant decline in the U.S. dollar.

U.S. equities ended 2004 in a strong rally, but remained in a fairly narrow
trading range for the first two months of 2005. Divergences were notable among
sectors, with energy emerging as a clear leader. On the positive side,
corporations have accelerated their hiring plans, capital spending remains
reasonably robust and merger-and-acquisition activity has increased. Offsetting
the positives are slowing corporate earnings growth, renewed energy price
concerns and the potential for an economic slowdown. International equities,
particularly in Asia, have benefited from higher economic growth rates (China
recorded growth of 9.3% in 2004), stronger currencies and relatively reasonable
valuations.

The major action in the bond market has been a flattening of the yield curve. As
short-term interest rates continued to rise, yields on the long end of the curve
remained relatively stable -- even declining at certain points since the Fed's
monetary tightening program began in June 2004. This phenomenon has been largely
attributed to continued foreign interest in U.S. bonds, which has served to
absorb much of the excess supply. By period-end, many believed long-term yields
were long overdue for a rise.

Looking ahead, the environment is likely to be a challenging one for investors,
with diversification and selectivity becoming increasingly important themes.
With this in mind, we encourage you to meet with your financial advisor to
review your goals and asset allocation and to rebalance your portfolio, as
necessary, to ensure it remains aligned with your objectives and risk tolerance.
As always, we thank you for trusting Merrill Lynch Investment Managers with your
investment assets, and we look forward to serving you in the months and years
ahead.

                                                Sincerely,


                                                /s/ Robert C. Doll, Jr.

       DIVERSIFIED INCOME STRATEGIES PORTFOLIO, INC.    FEBRUARY 28, 2005      3


A Discussion With Your Fund's Portfolio Manager

      We are pleased to provide you with this first shareholder report for
Diversified Income Strategies Portfolio, Inc. The Portfolio commenced trading on
the New York Stock Exchange on January 31, 2005.

What is the Portfolio's investment objective?

The Portfolio's objective is to provide shareholders with high current income.
We seek to achieve this objective by investing primarily in a diversified
portfolio of floating rate debt securities and instruments. The Portfolio also
may invest to a lesser extent in fixed rate debt securities and instruments. We
anticipate that a substantial portion of the Portfolio will consist of floating
rate and fixed rate debt securities that are rated below investment grade by the
established rating services, although the Portfolio also may invest in
investment grade securities.

Describe the recent market environment for high yield investing.

At the Portfolio's inception in January 2005, the high yield market had just
completed a year of solid performance. The Credit Suisse First Boston (CSFB)
High Yield Index returned 11% in calendar-year 2004, far lower than the 29%
return recorded in 2003, but still quite respectable. High yield bond issuance
in 2004 totaled $131 billion, slightly down from $133 billion in 2003. As in
2003, where 79% of proceeds were used to refinance existing debt, some 69% of
the proceeds went for refinancing in 2004 as corporate treasurers continued to
exploit cheaper financing opportunities. While the yield on the 10-year Treasury
note (which is the typical reference rate for high yield bonds) has not changed
appreciably over the past two years, the required spread off of Treasury
securities for high yield bonds has narrowed significantly. This spread
compression has been the principal driver of the high yield bond rally, and has
presented these refinancing opportunities. The high yield market momentum slowed
somewhat in 2005, with a year-to-date return of +1.31% as of February 28, 2005.

The market's appetite for risk was greater in 2004 than in 2003, as measured by
the major rating agencies. Issues rated B and lower accounted for 62% of 2004's
high yield bond volume compared to 63% for 2003, 54% for 2002 and 45% for 2001.
Moreover, CCC and split-CCC issuance was 7.2% in 2004 versus 3.0% in 2003 and
0.4% in 2002. Despite this, credit measures remained relatively intact.
Debt/EBITDA (earnings before interest, taxes, depreciation and amortization) in
2003 was 4.9 times versus 5.0 times in 2004. Interest coverage in 2003 was 2.5
times versus 2.7 times in 2004. The anomaly of better interest coverage despite
higher leverage is explained by compression-driven lower spreads for high yield
bonds. Default rates continued to decline in 2004 to 1.27% versus 4.13% in 2003
and 15.41% in 2002. While 2002 saw the highest default rate ever, 2004 saw the
lowest since 1997, according to CSFB.

How has the Portfolio performed since its inception?

Since inception (January 31, 2005) through February 28, 2005, the Common Stock
of Diversified Income Strategies Portfolio, Inc. had net annualized yields of
7.66% and 7.34%, based on a period-end per share net asset value of $19.16 and a
per share market price of $20.00, respectively, and $.117 per share income
dividends. Over the same period, the total investment return on the Portfolio's
Common Stock was +.31%, based on a change in per share net asset value from
$19.10 to $19.16.

For a description of the Portfolio's total investment return based on a change
in the per share market value of the Portfolio's Common Stock (as measured by
the trading price of the Portfolio's shares on the New York Stock Exchange), and
assuming reinvestment of dividends, please refer to the Financial Highlights
section of this report. As a closed-end fund, the Portfolio's shares may trade
in the secondary market at a premium or discount to the Portfolio's net asset
value. As a result, total investment returns based on changes in the market
value of the Portfolio's Common Stock can vary significantly from total
investment returns based on changes in the Portfolio's net asset value.


4      DIVERSIFIED INCOME STRATEGIES PORTFOLIO, INC.    FEBRUARY 28, 2005


How has the Portfolio been managed since its inception?

At period-end, it had been just one month since the Portfolio's inception, and
we have been working to invest the $254 million in proceeds raised during the
initial public offering. We are looking to invest the assets primarily in a
diversified portfolio of high yield (non-investment grade) debt securities that
pay a floating rate of interest. Floating rate debt securities include fixed
rate debt securities where the Portfolio has entered into certain derivative
transactions, including interest rate swaps, in an attempt to convert the fixed
rate payments into floating rate payments. We also have the ability to invest to
a lesser extent in fixed rate and investment grade securities, and are taking
advantage of the Portfolio's flexibility.

Since June 2004, the Federal Reserve Board (the Fed) has raised interest rates
25 basis points (.25%) at each of its meetings, bringing the federal funds rate
from 1% to 2.75%. The consensus view is that the Fed will continue its measured
monetary tightening program until the target rate reaches a point of
"neutrality," which most have placed in the area of 3% to 4%. Although long-term
interest rates have been slow to follow short-term interest rates higher -- a
market phenomenon that even Fed Chairman Alan Greenspan has called a "conundrum"
- -- we continue to believe that rising long-term interest rates are the primary
threat to investors in the high yield market. We believe a diversified portfolio
consisting primarily of floating rate securities can help investors protect
against the negative price impact of higher interest rates while still
participating in the higher yields available in the market.

We expect the Portfolio's ramp-up phase (the process of investing the initial
assets) to take us through March, and we look forward to providing a more
comprehensive discussion of portfolio activity in our next report to
shareholders.

12     DIVERSIFIED INCOME STRATEGIES PORTFOLIO, INC.    FEBRUARY 28, 2005


Notes to Financial Statements

1. Significant Accounting Policies:

Diversified Income Strategies Portfolio, Inc. (the "Fund") is registered under
the Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. Prior to commencement of operations on January
31, 2005, the Fund had no operations other than those relating to organizational
matters and the sale of 5,236 shares of Common Stock on January 18, 2005 to Fund
Asset Management, L.P. ("FAM") for $100,008. The Fund's 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 Fund determines and makes available for
publication the net asset value of its Common Stock on a daily basis. The Fund's
Common Stock is listed on the New York Stock Exchange ("NYSE") under the symbol
DVF.

(a) Corporate debt obligations -- The Fund invests principally in debt
obligations of companies, including Corporate Loans made by banks and other
financial institutions and both privately and publicly offered corporate bonds
and notes. Because agents and intermediaries are primarily commercial banks or
other financial institutions, the Fund's investment in Corporate Loans could be
considered concentrated in financial institutions.

(b) Valuation of investments -- Corporate Loans are valued in accordance with
guidelines established by the Board of Directors. Corporate Loans are valued at
the mean between the last available bid and asked prices from one or more
brokers or dealers as obtained from Loan Pricing Corporation. For the limited
number of Corporate Loans for which no reliable price quotes are available, such
Corporate Loans may be valued by Loan Pricing Corporation through the use of
pricing matrixes to determine valuations. If the pricing service does not
provide a value for a Corporate Loan, the Investment Adviser will value the
Corporate Loan at fair value, which is intended to approximate market value.

Securities that are held by the Fund that are traded on stock exchanges or the
Nasdaq National Market are valued at the last sale price or official close price
on the exchange on which such securities are traded, 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 ask price for
short positions. In cases where 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 Fund. Long positions in
securities traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or
Bulletin Board are valued at the last available bid price or yield equivalent
obtained from one or more dealers or pricing services approved by the Board of
Directors of the Fund. Short positions in securities traded in the OTC market
are valued at the last available ask 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. When the Fund writes an option, the
amount of the premium received is recorded on the books of the Fund as an asset
and an equivalent liability. The amount of the liability is subsequently valued
to reflect the current market value of the option written, based on the last
sale price in the case of exchange-traded options or, in the case of options
traded in the OTC market, the last ask price. Options purchased by the Fund are
valued at their last sale price in the case of exchange-traded options or, in
the case of options traded in the OTC market, the last bid price. The value of
swaps, including interest rate swaps, caps and floors, will be determined by
obtaining dealer quotations. Other investments, including futures contracts and
related options, are stated at market value. Obligations with remaining
maturities of 60 days or less are valued at amortized cost unless the Investment
Adviser believes that this method no longer produces fair valuations. Repurchase
agreements will be valued at cost plus accrued interest. The Fund employs
certain pricing services to provide securities prices for the Fund. Securities
and 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 Fund, including valuations furnished by the pricing services
retained by the Fund, which may use a matrix system for valuations. The
procedures of a pricing service and its valuations are reviewed by the officers
of the Fund under the general supervision of the Board of Directors. Such
valuations and procedures will be reviewed periodically by the Board of
Directors.

Generally, trading in foreign securities, as well as U.S. Government securities
and money market instruments, 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


       DIVERSIFIED INCOME STRATEGIES PORTFOLIO, INC.    FEBRUARY 28, 2005     13


Notes to Financial Statements (continued)

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 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.

(c) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the 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.

o     Financial futures contracts -- The 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     Options -- The 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 is less
      than or exceeds the premiums paid or received).

      Written and purchased options are non-income producing investments.

o     Swaps -- The 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 realized upon termination of the
      swap agreements. Swaps are marked-to-market daily based on dealer-supplied
      valuations 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.

(d) Income taxes -- 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.
Therefore, no federal income tax provision is required.

(e) 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. Interest income is recognized on the accrual basis. The
Fund amortizes all premiums and discounts on debt securities.

(f) Offering costs -- Direct expenses relating to the public offering of the
Fund's Common Stock were charged to capital at the time of issuance of the
shares.

(g) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates. The Fund may at times pay out less than the entire amount of
net investment income earned in any particular period and may at times pay out
such accumulated undistributed income


14     DIVERSIFIED INCOME STRATEGIES PORTFOLIO, INC.    FEBRUARY 28, 2005


Notes to Financial Statements (continued)

in other periods to permit the Fund to maintain a more stable level of
dividends.

(h) Securities lending -- The 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.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with FAM. The general
partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited
partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .75% of the Fund's average daily net assets plus the proceeds
of any outstanding borrowings used for leverage. During the Fund's start-up
phase, FAM elected to waive a portion of its management fee. For the period
January 31, 2005 to February 28, 2005, FAM earned fees of $125,677, of which
$100,541 was waived.

The Fund has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, or its affiliates.
Pursuant to that order, the Fund also has retained Merrill Lynch Investment
Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending
agent for a fee based on a share of the returns on investment of cash
collateral. MLIM, LLC may, on behalf of the Fund, invest cash collateral
received by the Fund for such loans, among other things, in a private investment
