Total Returns as of March 31, 2005 6-month 12-month ================================================================================================ U.S. equities (Standard & Poor's 500 Index) + 6.88% + 6.69% - ------------------------------------------------------------------------------------------------ Small-cap U.S. equities (Russell 2000 Index) + 8.00 + 5.41 - ------------------------------------------------------------------------------------------------ International equities (MSCI Europe Australasia Far East Index) +15.13 +15.06 - ------------------------------------------------------------------------------------------------ Fixed income (Lehman Brothers Aggregate Bond Index) + 0.47 + 1.15 - ------------------------------------------------------------------------------------------------ Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 1.21 + 2.67 - ------------------------------------------------------------------------------------------------ High yield bonds (Credit Suisse First Boston High Yield Index) + 3.39 + 7.84 - ------------------------------------------------------------------------------------------------ The U.S. economy continued to show resilience in the face of the Federal Reserve Board's (the Fed's) continued interest rate hikes and, more recently, higher oil prices. The Fed's measured tightening program brought the federal funds rate to 2.75% by period-end as the central bank continued its campaign to combat emergent inflation. In fact, business costs have been rising, which is beginning to put pressure on corporate profit margins. Consumer prices have been moving up as well, particularly in the areas of gasoline prices, healthcare costs, housing and education. U.S. equities ended 2004 in a strong rally, but stumbled into negative territory in the first quarter of 2005. On the positive side, corporations have been accelerating 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 later this year. International equities, especially in Asia, have benefited from higher economic growth rates. China, in particular, recorded growth of more than 9% in 2004. In the bond market, long-term interest rates finally began to inch higher while significant increases have been recorded on the short end. This resulted in a flattening of the yield curve throughout much of the current reporting period. At March 31, 2005, the two-year Treasury note yielded 3.80% and the 10-year note yielded 4.50%, a difference of 70 basis points (.70%). This compared to a spread of 151 basis points six months earlier and 226 basis points 12 months ago. 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. Robert C. Doll, Jr. President and Trustee WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 3 A Discussion With Your Fund's Portfolio Manager We maintained a relatively conservative approach throughout the year in recognition of rising interest rates, particularly in the short end of the yield curve. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended March 31, 2005, WCMA Government Securities Fund's Class 1, Class 2, Class 3 and Class 4 Shares paid shareholders net annualized dividends of .27%, .70%, 1.02% and 1.02%, respectively. For the six-month period ended March 31, 2005, the Fund's Class 1, Class 2, Class 3 and Class 4 Shares paid shareholders net annualized dividends of .50%, 1.11%, 1.43% and 1.43%, respectively. The Fund's seven-day yields as of March 31, 2005 were 1.14% for Class 1, 1.69% for Class 2, 2.01% for Class 3 and 2.01% for Class 4. The Fund's average portfolio maturity at March 31, 2005 was 41 days, compared to 47 days at September 30, 2004 and 60 days at March 31, 2004. We continued to employ a barbell strategy throughout the year. This involved emphasizing the very front end of the market (overnight and term financing) for liquidity and initially adding longer-dated securities for yield enhancement and price appreciation. As the Federal Reserve Board (the Fed) embarked on its "measured" monetary tightening campaign in June 2004, short-term interest rates began to rise -- and continued their advance throughout the Fund's fiscal year. This gave us reason to approach longer-dated securities with caution, as their market value tends to suffer more in a rising rate environment. As a result of managing the portfolio's average life and longer-dated holdings, the Fund was able to deliver highly competitive results relative to its peers. For the most part, the economy remained on solid footing throughout the past 12 months. Gross domestic product (GDP), which grew at an annualized rate of 4.5% in the first quarter of 2004, slowed to 3.3% in the second quarter before increasing to 4% in the third quarter and 3.8% in the fourth quarter. A similar level of GDP growth is expected in the first quarter of 2005. Gains in personal income contributed to GDP growth in 2004, although job creation has not been as robust as in previous economic recoveries. In the past several months, the major themes have centered on inflation and, in particular, the price of oil. Inflation appeared to pick up at the producer level, although a similar increase was not recorded at the consumer level. Nevertheless, the Fed continued to target higher interest rates to combat inflation expectations, bringing the federal funds rate to 2.75% by period-end. The Fed maintained its commitment to a measured monetary tightening program even in the face of rising oil prices, which many feared could increase inflationary pressures and threaten the economic growth forecasts at certain points throughout the period. However, the oil price shocks were largely absorbed by the markets. As short-term interest rates rose in symphony with the Fed's rate hikes, long-term interest rates remained stubbornly low, producing what Fed Chairman Alan Greenspan in February described as a "conundrum." The result was a considerable flattening of the yield curve over the past 12 months, with the two-year Treasury yield increasing 220 basis points (2.20%) while the 10-year Treasury yield increased just 65 basis points during the period. Notably, the short end of the curve has remained quite steep, with a 100 basis point spread between three-month and two-year Treasury securities at period-end. Issuance of Treasury securities continued to increase, largely to fund the significant twin deficits. Notably, the heavy supply continued to be absorbed by foreign interest in holding U.S. assets, despite the declining value of the U.S. dollar. The Treasury has remained prudent in its issuance of bills by adjusting the size of the weekly four-week bill as a cash management tool. In addition, the government's increased collection of both corporate and individual payroll taxes -- coincident with improving employment -- has helped offset the need for additional supply in the short end. How did you manage the portfolio during the period? Primarily, our approach to managing the Trust in this rising interest rate environment has been to maintain a relatively short average portfolio maturity. 4 WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 While we continued to manage the Trust by employing a barbelled approach throughout the period, we believed the two-year sector would give up the most ground in a rising interest rate environment. As a result, we did not participate in longer-dated securities and focused primarily on increasing our liquidity profile, namely in repurchase agreements and shorter-dated Treasury issues. We targeted one-year maturities as the fulcrum point of the yield curve and ultimately determined that the six-month to one-year sector offered the best opportunity for yield enhancement and price appreciation. At the short-end, we maintained approximately three-quarters of net assets in repurchase agreements, which comprised primarily overnight and one-week maturities. This sector resets to market rates much quicker than longer-dated securities while also allowing the Fund ample liquidity. How would you characterize the portfolio's position at the close of the period? Our positioning at period-end could be best described as "cautious." From a market perspective, the interesting question centers on when the Fed may become more data dependent in determining monetary policy. Consensus expectations at this point are that the Fed will continue its measured approach to rate increases until the federal funds rate reaches a "neutral" level (relative to inflation) in the area of 3.5%. This is likely to take us to at least mid-year, at which point the Fed may pause to consider the impact of its tightening program and evaluate future moves. While the deficits and the resultant heavy supply are here to stay, the Treasury has made it clear that any measurable increase in new debt will take place further out on the yield curve, particularly in the 10-year area. Given the recent employment situation and increased tax receipts this April (versus April 2004), we anticipate that Treasury bill supply may be reduced at the short end of the yield curve. This would create a steeper curve in the front end as well as lower financing rates for Treasury securities versus other investment vehicles. Still, new issuance should remain fairly robust, mostly in the long end. Less certain is whether employment will continue to improve and how much of inflation at the producer price level will be passed on to the consumer. We will continue to monitor developments on these fronts, and will look for opportunities to lengthen the portfolio's average maturity if the economy exhibits signs of faltering. The Trust's portfolio composition, as a percent of net assets, at the end of March and as of our last report to shareholders is detailed below: - -------------------------------------------------------------------------------- 3/31/05 9/30/04 - -------------------------------------------------------------------------------- Repurchase Agreements .......................... 75.5% 67.8% U.S. Government Obligations .................... 23.8 31.8 Other Assets Less Liabilities .................. 0.7 0.4 --------------------- Total .......................................... 100.0% 100.0% ===================== John Ng Vice President and Portfolio Manager April 6, 2005 WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 5 Disclosure of Expenses Shareholders of this Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses, including advisory fees, distribution fees including 12(b)-1 fees, and other Fund expenses. The following example (which is based on a hypothetical investment of $1,000 invested on October 1, 2004 and held through March 31, 2005) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds. The first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher. Expenses Paid Beginning Ending During the Period* Account Value Account Value October 1, 2004 to October 1, 2004 March 31, 2005 March 31, 2005 ========================================================================================================== Actual ========================================================================================================== Class 1 $1,000 $1,002.50 $7.99 - ---------------------------------------------------------------------------------------------------------- Class 2 $1,000 $1,005.50 $4.95 - ---------------------------------------------------------------------------------------------------------- Class 3 $1,000 $1,007.10 $3.35 - ---------------------------------------------------------------------------------------------------------- Class 4 $1,000 $1,007.10 $3.35 ========================================================================================================== Hypothetical (5% annual return before expenses)** ========================================================================================================== Class 1 $1,000 $1,016.95 $8.05 - ---------------------------------------------------------------------------------------------------------- Class 2 $1,000 $1,020.00 $4.99 - ---------------------------------------------------------------------------------------------------------- Class 3 $1,000 $1,021.59 $3.38 - ---------------------------------------------------------------------------------------------------------- Class 4 $1,000 $1,021.59 $3.38 - ---------------------------------------------------------------------------------------------------------- * For each class of the Fund, expenses are equal to the annualized expense ratio for the class (1.60% for Class 1, .99% for Class 2, .67% for Class 3 and .67% for Class 4), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). Because the Fund is a feeder fund, the expense table example reflects the expenses of both the feeder fund and the master fund in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half-year divided by 365. 6 WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 Statement of Assets and Liabilities WCMA Government Securities Fund As of March 31, 2005 ================================================================================================================= Assets - ----------------------------------------------------------------------------------------------------------------- Investment in Master Government Securities Trust (the "Trust"), at value (identified cost--$411,662,818) ... $ 411,153,982 Prepaid expenses ...................................... 46,575 ------------- Total assets .......................................... 411,200,557 ------------- ================================================================================================================= Liabilities - ----------------------------------------------------------------------------------------------------------------- Payables: Administrator ...................................... $ 75,770 Distributor ........................................ 72,789 Other affiliates ................................... 6,990 155,549 ------------- Accrued expenses ...................................... 70,042 ------------- Total liabilities ..................................... 225,591 ------------- ================================================================================================================= Net Assets - ----------------------------------------------------------------------------------------------------------------- Net assets ............................................ $ 410,974,966 ============= ================================================================================================================= Net Assets Consist of - ----------------------------------------------------------------------------------------------------------------- Class 1 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ................ $ 1,673,782 Class 2 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ................ 11,984,625 Class 3 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ................ 19,342,277 Class 4 Shares of beneficial interest, $.10 par value, unlimited number of shares authorized ................ 8,147,696 Paid-in capital in excess of par ...................... 370,335,422 Unrealized depreciation allocated from the Trust--net .

See Notes to Financial Statements. WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 13 Notes to Financial Statements WCMA Government Securities Fund 1. Significant Accounting Policies: WCMA Government Securities Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a no load, diversified, open-end management investment company. The Fund seeks to achieve its investment objective by investing all of its assets in the Master Government Securities Trust (the "Trust"), which has the same investment objective and strategies as the Fund. The value of the Fund's investment in the Trust reflects the Fund's proportionate interest in the net assets of the Trust. The performance of the Fund is directly affected by the performance of the Trust. The financial statements of the Trust, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. 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. The percentage of the Trust owned by the Fund at March 31, 2005 was 43.9%. The Fund is divided into four classes, designated Class 1, Class 2, Class 3 and Class 4. Each Class 1, Class 2, Class 3 and Class 4 share represents interests in the same assets of the Fund and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that each class bears certain expenses related to account maintenance and the distribution of such shares and the additional incremental transfer agency costs resulting from the conversion of shares and have exclusive voting with respect to matters relating to such account maintenance and distribution expenditures. Income, expenses (other than expenses attributed to a specific class) and realized and unrealized gains and losses on investments are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- The Fund records its investments in the Trust at fair value. Valuation of securities held by the Trust is discussed in Note 1a of the Trust's Notes to Financial Statements, which are included elsewhere in this report. (b) Investment income and expenses -- The Fund records daily its proportionate share of the Trust's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own income and expenses. (c) 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. (d) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions to shareholders -- The Fund declares dividends daily and reinvests daily such dividends (net of non-resident alien tax and backup withholding tax withheld) in additional fund shares at net asset value. Dividends and distributions are declared from the total of net investment income and net realized gain or loss on investments. (f) Investment transactions -- Investment transactions in the Trust are accounted for on a trade date basis. 2. Transactions with Affiliates: The Fund has entered into an Administration Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Fund pays a monthly fee at an annual rate of ..25% of the Fund's average daily net assets for the performance of administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. The Fund has adopted a Distribution Plan in compliance with Rule 12b-1 under the Investment Company Act of 1940, pursuant to which Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, receives account maintenance and distribution fees from the Fund. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares of the Fund as follows: - -------------------------------------------------------------------------------- Account Distribution Maintenance Fee Fee - -------------------------------------------------------------------------------- Class 1 ................................. .25% .75% Class 2 ................................. .25% .425% Class 3 ................................. .25% .125% Class 4 ................................. .25% .125% - -------------------------------------------------------------------------------- The ongoing account maintenance fee compensates MLPF&S for providing account maintenance services to shareholders. The ongoing distribution fee compensates MLPF&S for providing shareholder and distribution related services to shareholders. The Fund has entered into a contractual arrangement with FAM and MLPF&S to waive and/or reimburse a portion of the Fund's fees and expenses to ensure that the net expenses for the Fund's Class 2 Shares is .32% higher than 14 WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 Notes to Financial Statements (continued) WCMA Government Securities Fund that of CMA Government Securities Fund, and Class 3 and Class 4 Shares is equal to that of CMA Government Securities Fund. The fee/expense waiver or reimbursement includes account maintenance and distribution fees. This arrangement has a one-year term and is renewable. The Distributor has voluntarily agreed to waive a portion of its distribution fees in order to ensure that each class of shareholders receive a positive yield on each daily dividend. For the year ended March 31, 2005, FAM and MLPF&S have earned $1,153,881 and $2,188,306, respectively, of which $1,402,909 was waived and/or reimbursed. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. Interest is earned by the Fund from FDS based on the difference, if any, between estimated and actual daily beneficial share activity, which results in uninvested net proceeds from sales of Fund shares. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. 3. Beneficial Interest Transactions: Net increase (decrease) in net assets derived from beneficial interest transactions was $(129,873,585) and $541,257,315 for the years ended March 31, 2005 and March 31, 2004, respectively.

Report of Independent Registered Public Accounting Firm WCMA Government Securities Fund To the Shareholders and Board of Trustees of WCMA Government Securities Fund: We have audited the accompanying statement of assets and liabilities of WCMA Government Securities Fund as of March 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the respective periods then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of WCMA Government Securities Fund as of March 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the respective periods then ended, in conformity with U.S. generally accepted accounting principles.

See Notes to Financial Statements. 22 WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 Notes to Financial Statements Master Government Securities Trust 1. Significant Accounting Policies: Master Government Securities Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interest in the Trust, subject to certain limitations. The Trust'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 the estimates. The following is a summary of significant accounting policies followed by the Trust. (a) Valuation of investments -- Portfolio securities with remaining maturities of greater than sixty days, for which market quotations are readily available, are valued at market value. As securities transition from sixty-one to sixty days to maturity, the difference between the valuation existing on the sixty-first day before maturity and maturity value is amortized on a straight-line basis to maturity. Securities maturing sixty days or less from their date of acquisition are valued at amortized cost, which approximates market value. For the purpose of valuation, the maturity of a variable rate security is deemed to be the next coupon date on which the interest rate is to be adjusted. Other investments and assets for which market quotations are not available are valued at fair value as determined in good faith by or under the direction of the Trust's Board of Trustees. (b) Repurchase agreements -- The Trust may invest 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) Income taxes -- The Trust is classified as a partnership for federal income tax purposes. As such, each investor in the Trust is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Trust. Therefore, no federal income tax provision is required. It is intended that the Trust's assets will be managed so an investor in the Trust can satisfy the requirements of subchapter M of the Internal Revenue Code. (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. Interest income (including amortization of premium and discount) is recognized on the accrual basis. 2. Investment Advisory Agreement and Transactions with Affiliates: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("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 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 based upon the average daily value of the Trust's net assets, at the following annual rates: .25% of the Trust's average daily net assets not exceeding $500 million; .175% of the average daily net assets in excess of $500 million but not exceeding $1 billion; and .125% of the average daily net assets in excess of $1 billion. For the year ended March 31, 2005, the Trust reimbursed FAM $22,323 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, and/or ML & Co. WCMA GOVERNMENT SECURITIES FUND MARCH 31, 2005 23 Report of Independent Registered Public Accounting Firm Master Government Securities Trust To the Investors and Board of Trustees of Master Government Securities Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Government Securities Trust as of March 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the respective periods then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2005, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master Government Securities Trust as of March 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the respective periods then ended, in conformity with U.S. generally accepted accounting principles.
