The year, which opened with geopolitical turmoil, unrelenting economic uncertainty and a dismal continuation of a three-year equity market slump, vigorously reversed course in the months that followed. As we entered 2004, the equity markets maintained their positive momentum from year-end 2003. For the six-month and 12-month periods ended January 31, 2004, the Standard & Poor's (S&P) 500 Index returned +15.23% and +34.57%, respectively. In the fixed income markets, investors willing to accept the greatest risk were rewarded the most. The high yield market, for example, provided a return of +12.07% over the past six months and +26.96% for the 12-month period ended January 31, 2004, as measured by the Credit Suisse First Boston High Yield Index. At this time, the major signposts indicate that we are seeing a shift from economic growth fueled primarily by fiscal and monetary stimulus to a broader-based, self-sustaining economic expansion. Gross domestic product growth, which peaked at an annualized rate of 8.2% in the third quarter of 2003, is estimated at a more sustainable 4% in the fourth quarter. That level of growth is expected to repeat itself in the first quarter of 2004. For its part, the Federal Reserve Board has reiterated its willingness to keep short-term interest rates at current low levels to ensure the economy's strength. Accompanying the increase in economic activity was an improvement in corporate earnings. By the end of January, 298 of the S&P 500 companies had reported their fourth-quarter results, and 67.4% of those exceeded expectations. In the meantime, the American consumer, who continued to spend despite the faltering economy, may get further incentive from another round of Federal tax refunds in 2004. At Merrill Lynch Investment Managers, we believe the events and efforts of 2003 leave us with a much stronger economy and recent optimism suggests it is time for investors to consider what can go right in 2004. We encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. 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/ Terry K. Glenn Terry K. Glenn President and Trustee MERRILL LYNCH NATURAL RESOURCES TRUST JANUARY 31, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager The Trust outperformed the benchmark S&P 500 Index for the period mainly because of strong performance from its positions in natural gas supply companies. How did the Trust perform during the period in light of the existing market conditions? For the six-month period ended January 31, 2004, Merrill Lynch Natural Resources Trust's Class A, Class B, Class C and Class I Shares had total returns of +19.85%, +19.42%, +19.43% and +20.00%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 6 and 7 of this report to shareholders.) For the same period, the Trust's unmanaged benchmark, the Standard & Poor's (S&P) 500 Index, returned +15.23%, and its comparable Lipper category of Natural Resources Funds had an average return of +24.57%. (Funds in this Lipper category invest primarily in natural resources stocks.) The Trust's outperformance of the S&P 500 Index is attributed primarily to an overweight position in the natural gas supply subsector. Stocks in this area benefited as natural gas prices generally rose during the period. Detracting from performance, particularly relative to the Lipper Natural Resources Funds peer group, were low returns from our equity holdings in the oil service sector, where earnings lagged expectations due to restrained spending by the energy industry despite high oil and gas prices. In addition, share prices of metals and mining stocks soared during the period, and those funds focused on these sectors generally outperformed more diversified natural resources funds. While energy stocks languished, a strong rally in mining shares helped propel many of the pure materials-oriented funds in the Lipper group. What changes were made to the portfolio during the period? We continued to invest in gas-leveraged exploration and production companies in the United States and Canada. In the United States, we added to our holdings in Energy Partners, Ltd. and Burlington Resources Inc. In Canada, we initiated positions in Ketch Resources Ltd. and StarPoint Energy Ltd. and added to our existing holding in Atlas Energy Ltd. We also established a position in Nexen Inc., a senior Canadian independent company that has diversified away from Yemen and now has promising exploration prospects in the Gulf of Mexico and the Alberta oil sands. In an effort to gain exposure to the materials sector, we purchased Canico Resource Corp., which we believe has positive nickel prospects. We also added Northern Orion Resources Inc., given its copper and gold production potential. We reduced our position in Celanese AG, a global industrial chemicals company, following its acquisition bid from the Blackstone Group LP. We sold our shares in Agnico-Eagle Mines Limited following the company's continued operating and production problems at its LaRonde mine. We trimmed our positions in Impact Energy Inc. and Olympia Energy Inc. given their lower-than-expected gas production growth. We also sold Cequel Energy Inc. following the stock's strong performance. Finally, in recognition of an improving economy, we modestly increased the portfolio's cyclical exposure with purchases of several metals and gold production companies. 4 MERRILL LYNCH NATURAL RESOURCES TRUST JANUARY 31, 2004 How would you characterize the Trust's position at the close of the period? We continued to position the Trust to benefit from the very tight supply-and-demand dynamics in the North American natural gas markets. Gas production in both the United States and Canada appeared to decline in 2003, despite a resurgence in gas-drilling activity. Given that the solutions to the natural gas supply problem are at least two to three years away, we believe investments in gas producers and oil service companies leveraged to gas drilling activity will provide attractive returns. Even with milder weather conditions, the price of natural gas failed to break below the mid $4 per thousand cubic feet level, and modest cold weather sent it back above $7 per thousand cubic feet. We believe a hot summer or normal-to-cold winter will lead to continued strength in natural gas prices. As of January 31, 2004, 90.7% of the Trust's net assets was invested in stocks and 9.3% in cash equivalents. More than 85% of the portfolio's stock investments were in energy-related companies, with the remaining equity holdings primarily in metals, forest products and precious metals companies. Robert M.

Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com to obtain more current performance information. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gains distributions at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

See Notes to Financial Statements. MERRILL LYNCH NATURAL RESOURCES TRUST JANUARY 31, 2004 17 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements 1. Significant Accounting Policies: Merrill Lynch Natural Resources Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended, as a non-diversified, open-end management investment company. The Trust's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The Trust offers multiple classes of shares. Shares of Class A and Class I are sold with a front-end sales charge. Shares of Class B and Class C may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A, Class B and Class C Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its account maintenance and distribution expenditures. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses on investments and foreign currency transactions are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Trust. (a) Valuation of investments -- Equity securities that are held by the Trust 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, 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 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 Trustees of the Trust. Long positions 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 Trustees of the Trust. Short positions 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. Options written are valued at 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 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. Swap agreements are valued daily based upon quotations from market makers. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. 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 are valued at cost plus accrued interest. The Trust employs pricing services to provide certain securities prices for the Trust. 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 Trustees of the Trust, including valuations furnished by the pricing services retained by the Trust, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Trust's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. 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 New York Stock Exchange ("NYSE"). The values of such securities used in computing the net asset value of the Trust'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 of the Trust'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 Trust's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trust's Board of Trustees. 18 MERRILL LYNCH NATURAL RESOURCES TRUST JANUARY 31, 2004 Notes to Financial Statements (continued) (b) Repurchase agreements -- The Trust invests in U.S. government securities pursuant to repurchase agreements. Under such agreements, the counterparty agrees to repurchase the security at a mutually agreed upon time and price. The Trust takes possession of the underlying securities, marks to market such securities and, if necessary, receives additional securities daily to ensure that the contract is fully collateralized. If the counterparty defaults and the fair value of the collateral declines, liquidation of the collateral by the Trust may be delayed or limited. (c) Derivative financial instruments -- The Trust may engage in various portfolio investment strategies both to increase the return of the Trust 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 Forward foreign exchange contracts -- The Trust may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Trust as an unrealized gain or loss. When the contract is closed, the Trust records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. o Options -- The Trust may purchase and write covered call options and put options. When the Trust writes an option, an amount equal to the premium received by the Trust 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 Trust enters into a closing transaction), the Trust 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 greater than the premiums paid or received). Written and purchased options are non-income producing investments. (d) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. (e) Income taxes -- It is the Trust'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. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends, and capital gains at various rates. (f) 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. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Trust has determined the ex-dividend dates. Interest income is recognized on the accrual basis. (g) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (h) Dividends and distributions -- Dividends and distributions paid by the Trust are recorded on the ex-dividend dates. MERRILL LYNCH NATURAL RESOURCES TRUST JANUARY 31, 2004 19 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) (i) Securities lending -- The Trust 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 Trust and any additional required collateral is delivered to the Trust on the next business day. Where the Trust receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Trust typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Trust 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 Trust 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 Trust could experience delays and costs in gaining access to the collateral. The Trust 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 Trust has entered into an Investment Advisory Agreement with Merrill Lynch Investment Managers, L.P. ("MLIM"). The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Trust has also entered into a Distribution Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc. MLIM is responsible for the management of the Trust's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Trust. For such services, the Trust pays a monthly fee of .60%, on an annual basis, of the average daily value of the Trust's net assets. MLIM has entered into a Sub-Advisory Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM U.K."), an affiliate of MLIM, pursuant to which MLAM U.K. provides investment advisory services to MLIM with respect to the Trust. There is no increase in the aggregate fees paid by the Trust for these services. Pursuant to the Distribution Plans adopted by the Trust in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Trust pays the Distributor ongoing account maintenance and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: - -------------------------------------------------------------------------------- Account Distribution Maintenance Fee Fee - -------------------------------------------------------------------------------- Class A ................................ .25% -- Class B ................................ .25% .75% Class C ................................ .25% .75% - -------------------------------------------------------------------------------- Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account maintenance and distribution services to the Trust. The ongoing account maintenance fee compensates the Distributor and MLPF&S for providing account maintenance services to Class A, Class B and Class C shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B and Class C shareholders. 20 MERRILL LYNCH NATURAL RESOURCES TRUST JANUARY 31, 2004 Notes to Financial Statements (continued) For the six months ended January 31, 2004, FAMD earned underwriting discounts and MLPF&S earned dealer concessions on sales of the Trust's Class A and Class I Shares as follows: - -------------------------------------------------------------------------------- FAMD MLPF&S - -------------------------------------------------------------------------------- Class A ............................ $ 4,499 $53,122 Class I ............................ $ 51 $ 605 - -------------------------------------------------------------------------------- For the six months ended January 31, 2004, MLPF&S received contingent deferred sales charges of $9,818 and $1,530 relating to transactions in Class B and C Shares, respectively. The Trust has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to MLPF&S or its affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, 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 Trust, invest cash collateral received by the Trust for such loans, among other things, in a private investment company managed by MLIM or in registered money market funds advised by MLIM or its affiliates. As of January 31, 2004, the Trust lent securities with a value of $1,742,388 to MLPF&S or its affiliates.
