(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 3 and 4 of this report to shareholders.) The Trust's unmanaged benchmarks, the Morgan Stanley Capital International Natural Resources Index and the Standard & Poor's 500 Index, had total returns of -6.75% and -5.26%, respectively for the six-month period. The Trust's relative outperformance was a result of our focus on companies exposed to North American natural gas production, as well as oil service companies that are leveraged to natural gas drilling activity. For the past three years, our commodity research indicated that increasingly rapid depletion of natural gas would lead to reduced supplies of natural gas that we believed would lead to a strong natural gas pricing environment. We believe that this supply and demand imbalance point was reached in 2002, and that natural gas prices most likely will trade at significantly higher levels than their historic range for at least the next few years. U.S. production of natural gas appears to have fallen by 5% in 2002, and there is the potential that production could fall again in 2003 unless drilling activity increases significantly from current levels. The number of rigs drilling for natural gas has gradually recovered to the mid-700 level from a low of 612 reached in April 2002. However, even when rig activity peaked at 1,058 in July 2001, gas production only increased by 1.5% that year. Current activity with 300 fewer rigs drilling for gas implies that production may continue to fall. In addition, Canadian exports of natural gas that rose during the past decade to balance U.S. demand may also have peaked. Canadian production is estimated to have fallen by 1% last year, and a weather-shortened drilling season this winter may result in fewer well completions than planned. In addition, increasing demand for Canadian gas needed for Canada's heavy oil production could reduce imports into our markets. Inventories of natural gas have the potential to reach record low levels this year. While we started the winter heating season with 3.2 trillion cubic feet (TCF) in storage, we now have 838 billion cubic feet (BCF), or 1,003 BCF below last year's level and 500 BCF below the five-year average. Continued normal winter weather could see storage decline below the record low level of 697 BCF seen in 1996. Given current production rates, it is going to be difficult to refill storage prior to the next heating season. If the industry refilled at the average injection rate of the past five years, natural gas in storage would only reach 2.5 TCF, a level that would not meet winter heating needs without interrupting gas deliveries to industrial customers. We anticipate that there will likely be significant closures of petrochemical, fertilizer and methanol plants that are not going to be viable at current gas prices above $6.00 per thousand cubic feet. Despite this demand loss, we believe that the need to refill storage prior to the next heating season will see gas prices exceeding the $5.00 per thousand cubic feet level into the spring of 2004. As of January 31, 2003, the Trust had 87% of its assets invested in energy-related sectors, up 7% from its energy exposure at the end of the prior fiscal year. We have continued to seek natural gas investments in both the United States and Canada. The Trust has reached its limit of 25% of assets in U.S. exploration and production companies, but we are continuing to buy gas-leveraged companies in Canada with 18% of our assets invested in that area. Many of the management teams of Canadian companies that were acquired in 2001 have returned to found new companies, and they are having success in growing production from Canada's less mature gas fields. In addition, they have been able to acquire assets that some power companies have needed to sell to restore eroded balance sheets. We believe that the better growth prospects for the small Canadian producers will 1 Merrill Lynch Natural Resources Trust January 31, 2003 attract additional interest as the crisis in natural gas supply gains investor attention. Oil service companies and drilling contractors combined are 27% of the Trust's assets. These sectors should begin to benefit from increased spending by the oil industry, although the recovery has been sluggish since many of the power and trading companies have reduced exploration and development spending because of their poor financial conditions following the decline in power prices and trading volumes. We had below-benchmark exposure to the large integrated oil companies, as depressed refining and petrochemical margins offset the benefit received from high oil prices. At January 31, 2002, the balance of Trust assets were invested in basic material companies, including investments made in gold mining companies. Strong demand from China has buoyed demand for many commodities, and basic material companies have seen relative strength in the share prices as a result. The price of gold has jumped to the highest price it has seen since 1996. Gold demand and supply balance improved in the market during the past year as a result of the decline in the dollar improving gold's affordability in local currency terms of other countries, as well as falling interest rates reducing the incentive for producers to hedge. In addition, gold production declined for the first time in years as capital available to small gold miners has declined from the financial markets. Given these improved fundamentals, the gold price has regained its traditional safe-haven status in times of turmoil. Market Outlook We anticipate that investment in resources will continue to be volatile in 2003, and may be subject to deterioration in global economic activity. Therefore, we believe that our focus on investments in North America natural gas will continue to offer the best prospects for total return. Natural gas prices recently spiked to over $9 per thousand cubic feet, and we believe that they will remain high given limited new supply sources for the next several years. While the restart of some liquefied natural gas (LNG) terminals will provide a modest supply boost in 2003, new LNG terminals face issues including permitting construction problems and long construction lead times. Pipelines to carry gas from Alaska and Canada's Northwest Territories will not be completed until 2007 or 2008 at the earliest. Therefore, we believe that our natural gas investments have the potential to offer continued attractive returns. As of January 31, 2003, the Trust's portfolio had 99.4% of net assets invested in equities and 0.6% in cash and cash equivalents. Approximately 87% of investments were energy related, with the remaining major investments in metals, gold mining and forest product companies. As a result of our focus on North American natural gas, the Trust was primarily invested in U.S. and Canadian-domiciled companies. In Conclusion We thank you for your continued support and interest in Merrill Lynch Natural Resources Trust, and we look forward to sharing our investment outlook and strategies with you in our next report to shareholders.

In addition, Class C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. o Class D Shares incur a maximum initial sales charge of 5.25% and an account maintenance fee of 0.25% (but no distribution fee). None of the past results shown should be considered a representation of future performance. 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. 14 Merrill Lynch Natural Resources Trust January 31, 2003 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 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 four classes of shares under the Merrill Lynch Select Pricing(SM) System. Shares of Class A and Class D 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 B, Class C and Class D 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 -- Portfolio securities that are traded on stock exchanges are valued at the last sale 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. Securities traded in the over-the-counter market are valued at the last available bid price prior to the time of valuation. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated by or under the authority of the Trustees of the Trust as the primary market. Securities that are traded both in the over-the-counter market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. In the case of options traded in the over-the-counter market, valuation is the last asked price (options written) or the last bid price (options purchased). Short-term securities are valued at amortized cost, which approximates market value. Other investments are stated at market value. Securities and other assets for which market value quotations are not available are valued at their fair value as determined in good faith by or under the direction of the Trustees of the Trust. (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 to increase or decrease the level of risk to which the Trust is exposed more quickly and efficiently than transactions in other types of instruments. 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 is authorized to 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 Fund 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 can 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 15 Merrill Lynch Natural Resources Trust January 31, 2003 NOTES TO FINANCIAL STATEMENTS (continued) 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. (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. 16 Merrill Lynch Natural Resources Trust January 31, 2003 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 B ................................ .25% .75% Class C ................................ .25% .75% Class D ................................ .25% -- - -------------------------------------------------------------------------------- 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 B, Class C and Class D 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. For the six months ended January 31, 2003, FAMD earned underwriting discounts and MLPF&S earned dealer concessions on sales of the Trust's Class A and Class D Shares as follows: - -------------------------------------------------------------------------------- FAMD MLPF&S - -------------------------------------------------------------------------------- Class A .............................. $ 19 $ 353 Class D .............................. $ 303 $4,497 - -------------------------------------------------------------------------------- For the six months ended January 31, 2003, MLPF&S received contingent deferred sales charges of $28,634 and $874 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. As of January 31, 2003, the Trust lent securities with a value of $2,139,900 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, LLC or in registered money market funds advised by MLIM or its affiliates. For the six months ended January 31, 2003, MLIM, LLC received $2,234 in securities lending agent fees. In addition, MLPF&S received $4,781 in commissions on the execution of portfolio security transactions for the Trust for the six months ended January 31, 2003. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Trust's transfer agent. For the six months ended January 31, 2003, the Trust reimbursed MLIM $1,160 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of MLIM, PSI, MLAM U.K., FDS, FAMD, and/or ML & Co. 3.
