('Total Return') produced a +1.55% return; Managed Municipal Fund, Inc. ('Managed Municipal') produced a +1.06% return; North American Government Bond Fund, Inc. ('North American') produced a +1.65% return in its Class A Shares and a +1.32% return in its Class C Shares; and ISI Strategy Fund ('Strategy') produced a +7.91% return. These figures assume the reinvestment of dividends and capital gain distributions, and exclude the impact of any sales charges. PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE AND IS NO GUARANTEE OF FUTURE RESULTS. CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE DATA QUOTED. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN ORIGINAL COST. FOR THE MOST RECENT MONTH-END PERFORMANCE OF A FUND, PLEASE CALL (800) 955-7175. DESCRIPTION OF FUND OBJECTIVES Total Return, Managed Municipal, North American and Strategy, (each a 'Fund' and collectively, the 'Funds') are registered under the Investment Company Act of 1940, as amended, as open-end management investment companies. The Funds are organized as corporations under the laws of the state of Maryland. International Strategy & Investment, Inc. ('ISI') manages all four Funds. Total Return's investment objective is to achieve a high level of total return with relative stability of principal and, secondarily, high current income consistent with an investment in securities issued by the United States Treasury. Managed Municipal's investment objective is designed to provide a high level of total return with relative stability of principal and, secondarily, high current income exempt from federal income tax through investment in a portfolio consisting primarily of tax-free municipal obligations. North American's investment objective is designed to provide a high level of current income, consistent with prudent investment risk. Strategy's investment objective is designed to maximize total return through a combination of long-term growth of capital and current income. We would like to welcome new investors to the ISI Funds and thank those who have been with us for some time. We appreciate your confidence. Sincerely, /s/ R. Alan Medaugh R.

-------------------------------------------------------------------------------------------------------------------- /1/ PAST PERFORMANCE IS NOT INDICATIVE OF FUTURE RESULTS. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. The performance information presented in the graph and table above does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. All performance assumes the reinvestment of dividends and capital gain distributions and includes the Fund's maximum 3.00% sales charge. Distribution of the Fund's capital gains and non-US Treasury income may be subject to state and local taxes. Management is not aware of any single index that is truly representative of the Fund since its active maturity management policy allows the manager to adjust the weighted average maturity throughout each US Treasury sector. Currently the Fund's weighted average maturity is approximately 9.6 years. Performance would have been lower during the specified period if certain of the Fund's fees and expenses had not been waived. /2/ The Fund's inception date is August 10, 1988. Benchmark returns are for the periods beginning August 31, 1988. /3/ The Lehman Brothers Treasury Index is an unmanaged index reflecting the performance of all public Treasury obligations and does not focus on one particular segment of the Treasury market. The Lehman Brothers Intermediate Treasury Index is an unmanaged index reflecting the performance of US Treasury securities in the intermediate-term Treasury sector. The Lehman Brothers Long-Term Treasury Index is an unmanaged index reflecting the performance of US Treasury securities in the long-term Treasury sector.

Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. The performance information presented in the graph and table above does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. All performance assumes the reinvestment of dividends and capital gain distributions and includes the Fund's maximum 3.00% sales charge. For certain investors, a portion of the Fund's income may be subject to Federal alternative minimum tax. Distribution of the Fund's income and capital gains may be subject to state and local taxes. /2/ The Fund's inception date is February 26, 1990. Benchmark returns are for the periods beginning February 28, 1990. /3/ The Lehman Brothers General Obligation Index is an unmanaged index reflecting general municipal market performance. The Lehman Brothers Prerefunded Municipal Bond Index, an unmanaged index, is a subcomponent of the main Lehman Brothers Municipal Bond Index, and contains only bonds from the main index that have been prerefunded or escrowed to maturity. Benchmark returns do not reflect expenses or sales charges that have been deducted from the Fund's returns. /4/ The Consumer Price Index is a widely used measure of inflation. 3 NORTH AMERICAN

------------------------------------------------------------------------------------------------------ /1/ PAST PERFORMANCE IS NOT INDICATIVE OF FUTURE RESULTS. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. The performance information presented in the graph and table above does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. All performance assumes the reinvestment of dividends and capital gain distributions and includes the Fund's maximum 3.00% sales charge. Performance would have been lower during the specified period if certain of the Fund's fees and expenses had not been waived. /2/ The Fund's inception date is September 16, 1997. Benchmark returns are for the periods beginning September 30, 1997. /3/ The Dow Jones Wilshire 5000 (Full Cap) Index is an unmanaged index that represents the broadest measure of the US equity market. Benchmark returns do not reflect expenses or sales charges that have been deducted from the Fund's returns. /4/ The Consumer Price Index is a widely used measure of inflation. /5/ Lipper figures represent the average total returns by all the mutual funds designated by Lipper, Inc. as falling into the category indicated. The Lipper Flexible Portfolio Funds category includes funds that allocate their investments across various asset classes, including domestic common stocks, bonds and money market instruments with a focus on total return. Benchmark returns do not reflect expenses or sales charges that have been deducted from the Fund's returns. 6 SHAREHOLDER EXPENSE EXAMPLE As a shareholder of a Fund, you incur two types of costs: (1) transaction costs for certain share classes, including sales charges (loads) on purchase payments or other distributions; and (2) ongoing costs, including management fees, Rule 12b-1 distribution/shareholder service fees for certain share classes and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The following example is based on $1,000 invested on November 1, 2006 and held for the six months through April 30, 2007. ACTUAL EXPENSES - The "Actual Return" rows in the following table provide information about actual account values and actual expenses. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid During Period" column to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES - The "Hypothetical Return" rows in the following table provide information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the actual return of each Fund. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. Expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the "Hypothetical Return" rows in the table are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If these transactional costs were included, your costs would have been higher. 7 SHAREHOLDER EXPENSE EXAMPLE BEGINNING ENDING EXPENSES PAID ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE DURING EXPENSE NOVEMBER 1, 2006 APRIL 30, 2007 PERIOD/(1)/ RATIO - -------------------------------------------------------------------------------------------- TOTAL RETURN US TREASURY FUND Actual Return $1,000.00 $1,015.50 $3.80 0.76% Hypothetical Return $1,000.00 $1,021.03 $3.81 0.76% MANAGED MUNICIPAL FUND Actual Return $1,000.00 $1,010.58 $4.59 0.92% Hypothetical Return $1,000.00 $1,020.23 $4.61 0.92% NORTH AMERICAN GOVERNMENT BOND FUND ISI CLASS A SHARES Actual Return $1,000.00 $1,016.48 $5.40 1.08% Hypothetical Return $1,000.00 $1,019.44 $5.41 1.08% NORTH AMERICAN GOVERNMENT BOND FUND ISI CLASS C SHARES Actual Return $1,000.00 $1,013.20 $8.59 1.72% Hypothetical Return $1,000.00 $1,016.27 $8.60 1.72% ISI STRATEGY FUND Actual Return $1,000.00 $1,079.12 $5.36 1.04% Hypothetical Return $1,000.00 $1,019.64 $5.21 1.04% - -------------------------------------------------------------------------------- (1)Equals the Fund's annualized expense ratio for the period, multiplied by the average account value over the period, multiplied by the number of days in most recent fiscal half-year, divided by 365 to reflect the half-year period. 8 ISI FUNDS PORTFOLIO PROFILES (AS A % OF TOTAL NET ASSETS) (UNAUDITED) APRIL 30, 2007 TOTAL RETURN US TREASURY FUND US Treasury Obligations 96.66% Repurchase Agreements 1.90% Other Assets and Liabilities 1.44% ------- 100.00% MANAGED MUNICIPAL FUND Aaa* 75.10% Aa* 22.15% Repurchase Agreements 1.18% Other Assets and Liabilities 1.57% ------- 100.00% * Ratings are based on Moody's Investor Services, Inc.

See Notes to Financial Statements. 33 ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED) NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES A. ORGANIZATION Total Return US Treasury Fund, Inc. ('Total Return'), Managed Municipal Fund, Inc. ('Managed Municipal'), North American Government Bond Fund, Inc. ('North American') and ISI Strategy Fund, Inc. ('Strategy'), (each a 'Fund' and collectively, the 'Funds') are registered under the Investment Company Act of 1940, as amended, as open-end management investment companies. The Funds are organized as corporations under the laws of the State of Maryland. Total Return's investment objective is to achieve a high level of total return with relative stability of principal and, secondarily, high current income consistent with an investment in securities issued by the United States Treasury. Managed Municipal's investment objective is to provide a high level of total return with relative stability of principal and, secondarily, high current income exempt from Federal income tax through investment in a portfolio consisting primarily of tax-free municipal obligations. North American's investment objective is designed to provide a high level of current income, consistent with prudent investment risk. Strategy's investment objective is to maximize total return through a combination of long-term growth of capital and current income. Total Return, Managed Municipal and Strategy currently offer ISI Shares to investors. North American offers ISI North American Government Bond Fund Class A Shares ('ISI Class A Shares') and ISI North American Government Bond Fund Class C Shares ('ISI Class C Shares'). ISI Shares and North American's ISI Class A Shares are subject to a maximum front-end sales charge of 3.00%. A contingent deferred sales charge of 1.00% is imposed on the sale of North American's ISI Class C Shares if redeemed within the first year after purchase. Total Return, Managed Municipal and Strategy are authorized to issue 115,000,000, 55,000,000 and 25,000,000 shares, respectively, of ISI Shares at $0.001 par value. North American is authorized to issue 50,000,000 ISI Class A Shares and 5,000,000 ISI Class C Shares at $0.001 par value. B. VALUATION OF SECURITIES Exchange traded securities and over-the-counter securities listed on the NASDAQ National Market System for which market quotations are readily available are valued each Fund business day using the last reported sales price or the NASDAQ Official Closing Price ('NOCP'), provided by independent pricing services as of the close of trading on the New York Stock Exchange (normally 4:00 p.m. Eastern time). In the absence of a sale or NOCP, such securities are valued at the mean of the last bid and the last asked prices. Non-exchange traded securities for which over-the-counter quotations are readily available are generally valued at the mean between the last bid and last asked prices. Money market instruments that mature in 60 days or less may be valued at amortized cost unless the Fund's investment advisor believes another valuation is more appropriate. When valuing securities for which market quotations are not readily available or for which the market quotations that are available are considered unreliable, the Funds determine a fair value in good faith under procedures established by and under the general supervision of the Funds' Boards of Directors (the 'Board'). The Funds may use these procedures to establish the fair value of securities when, for example, a significant event occurs between the time the market closes and the time as of which the Funds value their investments if such an event is likely to affect the Fund's net asset value per share. Fair valuation may also be used for securities that are subject to legal or contractual restrictions on resale, securities for which no or limited trading activity has occurred for a period of time, or securities that are otherwise deemed to be illiquid (i.e., securities that cannot be disposed of within seven days at approximately the price at which the security is currently priced by the Funds). 34 ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED) If a fair value is required, the investment advisor or sub-advisor in the case of Strategy, determines the value of the security until the Board meets to establish the fair value of the security. As of April 30, 2007, there were no fair valued securities. C. SECURITIES TRANSACTIONS AND INVESTMENT INCOME Securities transactions are recorded on trade date. Realized gains and losses are determined by comparing the proceeds of a sale or the cost of a purchase with a specific offsetting transaction. Dividend income is recorded on the ex-dividend date. Interest income, including amortization of premiums and accretion of discounts, is accrued daily. Estimated expenses are also accrued daily. With respect to North American, income, gains (losses) and common expenses are allocated to each class based on its respective net assets. Class specific expenses are charged directly to each class. D. DISTRIBUTIONS Total Return declares a dividend daily, and Managed Municipal and North American declare monthly dividends at fixed rates approved by the Funds' Board. These dividends are paid monthly. To the extent that their net investment income and short-term capital gains are less than the approved fixed rate, some of their dividends may be paid from long-term capital gains or as a return of shareholder capital. Strategy declares and pays dividends quarterly from its net investment income. Net realized capital gains, if any, are distributed at least annually. The Funds record dividends and distributions on the ex-dividend date. A return of capital may occur for North American at October 31, 2007. The exact amount, if any, is undeterminable at this time. E. FEDERAL INCOME TAXES Each Fund has a policy to qualify as a regulated investment company under subchapter M of the Internal Revenue Code and to distribute all its taxable income. In addition, by distributing in each calendar year substantially all of its net income, capital gains and other amounts, if any, the Funds will not be subject to Federal excise taxes. Accordingly, no Federal income taxes have been accrued. F. FOREIGN CURRENCY TRANSLATION The Funds maintain their accounting records in US dollars. North American determines the US dollar value of foreign currency-denominated assets, liabilities and transactions by using prevailing exchange rates. In valuing assets and liabilities, North American uses the prevailing exchange rate on valuation date. In valuing security transactions, the receipt of income and the payment of expenses, North American uses the prevailing exchange rate on the transaction date. Net realized gains and losses on foreign currency transactions shown on North American's financial statements result from the sale of foreign bonds and foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and from the difference between the amounts of interest recorded on the Fund's books and the US dollar equivalent of the amounts actually received or paid. G. FORWARD FOREIGN CURRENCY CONTRACTS North American may use forward foreign currency contracts to manage foreign exchange rate risk. The Fund may use these contracts to fix the US dollar value of securities transactions for the period between the date of the transaction and the date the security is received or delivered or to hedge the US dollar value of securities that it already owns. The use of forward foreign currency contracts does not eliminate fluctuations in the prices of the underlying securities, but does establish a rate of exchange that can be achieved in the future. The Fund determines the net US dollar value of forward foreign currency contracts using prevailing exchange rates. As of April 30, 2007, there were no open forward currency contracts. 35 ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED) H. REPURCHASE AGREEMENTS The Funds may make short-term investments in repurchase agreements that are fully collateralized by US government securities. Under the terms of a repurchase agreement, a financial institution sells fixed-income securities to the Funds and agrees to buy them back on a specified day in return for the principal amount of the original sale plus accrued interest. The custodial bank holds the collateral in a separate account until the agreement matures. If the value of the securities falls below the principal amount of the repurchase agreement plus accrued interest, the financial institution deposits additional collateral by the following business day. If the financial institution either fails to deposit the required additional collateral or fails to repurchase the securities as agreed, the Funds have the right to sell the securities and recover any resulting loss from the financial institution. If the financial institution enters into bankruptcy, the Funds' claims on the collateral may be subject to legal proceedings. I. ESTIMATES In preparing its financial statements in conformity with US generally accepted accounting principles, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results may be different. NOTE 2 - NEW ACCOUNTING PRONOUNCEMENTS In June 2006, the Financial Accounting Standards Board ("FASB") issued Financial Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" (the "Interpretation") which is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the effective date. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management has recently begun to evaluate the application of the Interpretation, and has not at this time determined the impact, if any, resulting from its adoption on the Fund's financial statements. In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" (the "Statement") which is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. This Statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. Management has recently begun to evaluate the application of the Statement, and has not at this time determined the impact, if any, resulting from its adoption on the Fund's financial statements.

Investing in Canadian and Mexican government securities may have different risks than investing in US government securities. An investment in Canada or Mexico may be affected by developments unique to those countries. These developments may not affect the US economy or the prices of US government securities in the same manner. In addition, the value of bonds issued by non-US governments may be affected by adverse international political and economic developments that may not impact the value of US government securities. NOTE 6 - CONTRACTUAL OBLIGATIONS In the ordinary course of business, the Funds enter into contracts that contain a variety of indemnifications. Each Fund's maximum exposure under these arrangements is unknown. However, the Funds have not had prior claims or losses pursuant to these indemnification provisions and expect the risk of loss thereunder to be remote.
