This report covers the six-month reporting period ended April 30, 2008. For this period, the Total Return US Treasury Fund, Inc. (`Total Return') produced a +4.26% return; Managed Municipal Fund, Inc. (`Managed Municipal') produced a +2.39% return; North American Government Bond Fund, Inc. (`North American') produced a +4.54% return in its Class A Shares and a +4.22% return in its Class C Shares; and ISI Strategy Fund (`Strategy') produced a -7.71% 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 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 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. 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.

Benchmark returns do not reflect expenses or sales charges that have been deducted from the Fund's returns. 9 - -------------------------------------------------------------------------------- SHAREHOLDER EXPENSE EXAMPLES (UNAUDITED) - -------------------------------------------------------------------------------- As a shareholder of the Fund, you incur two types of cost: (1) transaction costs for certain share classes, including sales charges (loads); and (2) ongoing costs, including management fees, Rule 12b-1 distribution/shareholder service fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in each Fund and to compare these costs with the ongoing costs of investing in other mutual funds. A mutual fund's ongoing costs are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The expenses in the tables below are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. ACTUAL EXPENSES - "Actual Return" in the following table provides information about actual account values and actual expenses. You may use the information here, 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 - "Hypothetical Returns" in the following table provides 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 tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, "Hypothetical Returns" 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. 10 - -------------------------------------------------------------------------------- SHAREHOLDER EXPENSE EXAMPLE (UNAUDITED) (CONTINUED) - -------------------------------------------------------------------------------- TOTAL RETURN US TREASURY FUND BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID ANNUALIZED NOVEMBER 1, 2007 APRIL 30, 2008 DURING PERIOD(1) EXPENSE - ------------------------------------------------------------------------------------------------------------------- Based on Actual Fund Return.................... $1,000.00 $1,042.60 $3.97 0.78% Based on Hypothetical 5% Return................ $1,000.00 $1,020.98 $3.92 0.78% - ------------------------------------------------------------------------------------------------------------------- MANAGED MUNICIPAL FUND BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID ANNUALIZED NOVEMBER 1, 2007 APRIL 30, 2008 DURING PERIOD(1) EXPENSE - ------------------------------------------------------------------------------------------------------------------- Based on Actual Fund Return.................... $1,000.00 $1,023.90 $4.81 0.96% Based on Hypothetical 5% Return................ $1,000.00 $1,020.11 $4.80 0.96% - ------------------------------------------------------------------------------------------------------------------- NORTH AMERICAN GOVERNMENT BOND FUND CLASS A BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID ANNUALIZED NOVEMBER 1, 2007 APRIL 30, 2008 DURING PERIOD(1) EXPENSE - ------------------------------------------------------------------------------------------------------------------- Based on Actual Fund Return.................... $1,000.00 $1,045.40 $5.82 1.15% Based on Hypothetical 5% Return................ $1,000.00 $1,019.17 $5.75 1.15% - ------------------------------------------------------------------------------------------------------------------- NORTH AMERICAN GOVERNMENT BOND FUND CLASS C BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID ANNUALIZED NOVEMBER 1, 2007 APRIL 30, 2008 DURING PERIOD(1) EXPENSE - ------------------------------------------------------------------------------------------------------------------- Based on Actual Fund Return.................... $1,000.00 $1,042.20 $8.97 1.77% Based on Hypothetical 5% Return................ $1,000.00 $1,016.08 $8.85 1.77% - ------------------------------------------------------------------------------------------------------------------- ISI STRATEGY FUND BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID ANNUALIZED NOVEMBER 1, 2007 APRIL 30, 2008 DURING PERIOD(1) EXPENSE - ------------------------------------------------------------------------------------------------------------------- Based on Actual Fund Return.................... $1,000.00 $ 922.90 $4.72 0.99% Based on Hypothetical 5% Return................ $1,000.00 $1,019.95 $4.96 0.99% - ------------------------------------------------------------------------------------------------------------------- (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 the most recent fiscal half-year, divided by 366 to reflect the half-year period. 11 - -------------------------------------------------------------------------------- ISI FUNDS (UNAUDITED) - -------------------------------------------------------------------------------- PORTFOLIO PROFILES (AS A % OF NET ASSETS) APRIL 30, 2008 TOTAL RETURN US TREASURY FUND US Treasury Obligations 97.75% Repurchase Agreements 1.04% Other Assets and Liabilities 1.21% ------- 100.00% MANAGED MUNICIPAL FUND Aaa* 75.38% Aa* 19.59% US Treasury Obligations 1.99% Repurchase Agreements 2.09% Other Assets and Liabilities 0.95% ------- 100.00% * Ratings are from Moody's Investors, Inc.

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 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 a single class of shares (ISI Shares) to investors. North American offers ISI Class A Shares and ISI Class C Shares. ISI Shares and ISI Class A Shares are subject to a maximum front-end sales charge equal to 3.00%. A contingent deferred sales charge of 1.00% is imposed on the sale of 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 price or NOCP, such securities are valued at the mean of the last bid and the last asked prices. Non-exchange traded securities for which quotations are readily available are generally valued at the mean between the last bid and the 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. 39 - -------------------------------------------------------------------------------- ISI FUNDS - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) When valuing securities for which market quotations are not readily available or for which the market quotations that are readily 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 calculation of the net asset value per share, and the 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). If a fair value is required, the investment advisor, or the 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, 2008, 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 dividends daily, and North American declares monthly dividends at fixed rates approved by the Board. These dividends are paid monthly. To the extent that a Fund's net investment income is less than an approved fixed rate, some of its dividends may be designated as a return of shareholder capital. Managed Municipal declares and pays dividends monthly from its net investment income. 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. 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 of its taxable income. In addition, by distributing in each calendar year substantially all of its net investment income and net realized capital gains, a Fund will not be subject to Federal excise taxes. Accordingly, no Federal income taxes have been accrued. 40 - -------------------------------------------------------------------------------- ISI FUNDS - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) F. FOREIGN CURRENCY TRANSLATION The Funds maintain their accounting records in U.S. dollars. North American determines the U.S. dollar value of foreign currency-denominated assets, liabilities and transactions by using prevailing exchange rates. 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 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 North American's books and the U.S. dollar equivalent of the amounts actually received or paid. That portion of realized gains (losses) from security transactions that results from fluctuation in foreign currency exchange rates relating to the sale of foreign securities is not separately disclosed but is included with net realized gains (losses) from security transactions. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed but is included with net change in unrealized appreciation/depreciation on investments. 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 U.S. 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 U.S. 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. North American determines the net U.S. dollar value of the forward foreign currency contracts using prevailing exchange rates. As of April 30, 2008, there were no open forward currency contracts. H. REPURCHASE AGREEMENTS Each Fund may make short-term investments in repurchase agreements that are fully collateralized by U.S. government securities. Under the terms of a repurchase agreement, a financial institution sells fixed-income securities to a Fund 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, a Fund has the right to sell the securities and recover any resulting loss from the financial institution. If the financial institution enters into bankruptcy, a Fund's claim on the collateral may be subject to legal proceedings. 41 - -------------------------------------------------------------------------------- ISI FUNDS - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) I. ESTIMATES In preparing its financial statements in conformity with U.S. 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 September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of SFAS No. 157 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of April 30, 2008, the Funds do not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements. However, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements reported on the statement of changes in net assets for a fiscal period. NOTE 3 - FEES AND TRANSACTIONS WITH AFFILIATES International Strategy & Investment, Inc. ("ISI") is the Funds' investment advisor. As compensation for its advisory services, Total Return pays ISI an annual fee based on the Fund's average daily net assets, which is calculated daily and paid monthly at the following annual rates: 0.20% of the first $100 million, 0.18% of the next $100 million, 0.16% of the next $100 million, 0.14% of the next $200 million and 0.12% of the amount over $500 million. In addition, Total Return pays ISI 1.50% of the Fund's gross interest income. Managed Municipal, North American and Strategy each pay ISI a fee, which is calculated daily and paid monthly, at the annual rate of 0.40% of such Fund's average daily net assets. ISI contractually agreed to waive its advisory fees and/or reimburse expenses of North American through February 28, 2009 to the extent necessary to limit the expenses of ISI Class C Shares to 1.85% of the average daily net assets attributable to such shares. During the six months ended April 30, 2008, ISI did not waive any advisory fees. Los Angeles Capital Management and Equity Research, Inc. is Strategy's Sub-Advisor and is responsible for managing the common stocks in Strategy's portfolio. The Sub-Advisor is paid by ISI, not Strategy. 42 - -------------------------------------------------------------------------------- ISI FUNDS - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) ISI Group, Inc. ("ISI Group"), an affiliate of ISI, is the distributor for the Funds. Total Return, Managed Municipal and Strategy each pay ISI Group a distribution/shareholder service fee, pursuant to Rule 12b-1, that is calculated daily and paid monthly at the annual rate up to 0.25% of their average daily net assets. North American's ISI Class A Shares and ISI Class C Shares pay ISI Group a distribution/shareholder service fee, pursuant to Rule 12b-1, that is calculated daily and paid monthly at the annual rate up to 0.40% and 1.00% (which may include up to 0.25% for shareholder servicing fees for each class) of their average daily net assets, respectively. During the six months ended April 30, 2008, North American Class A shares did not pay any shareholder servicing fees. During the six months ended April 30, 2008, ISI Group earned commissions on sales of ISI Shares of Total Return, Managed Municipal, and Strategy of $2,723, $5,348 and $5,773, respectively, and $11,750 on sales of ISI Class A Shares of North American. ISI Group retained $11,821 of contingent deferred sales charges on the sale of ISI Class C Shares of North American. Ultimus Fund Solutions, LLC ("Ultimus") is the administrator and fund accountant for the Funds pursuant to the terms of a Mutual Fund Services Agreement. Ultimus supplies non-investment related statistical and research data, internal regulatory compliance services and executive and administrative services. Ultimus supervises the preparation of tax returns, reports to shareholders of the Funds, reports to and filings with the SEC and state securities commissions, and materials for meetings of the Board of Directors. Ultimus also calculates the net asset value per share of each Fund and provides information necessary to prepare the Funds' financial statements and tax returns. For the performance of these services, the Funds pay Ultimus a fee at the annual rate of 0.10% of the combined average value of the daily net assets up to $500 million, 0.075% of such assets from $500 million to $1 billion, and 0.06% of such assets in excess of $1 billion, subject to an annual minimum of $500,000. Under the terms of a Transfer Agent and Shareholder Services Agreement, Ultimus maintains the records of each shareholder's account, answers shareholders' inquiries concerning their accounts, processes purchases and redemptions of each Fund's shares, acts as dividend and distribution disbursing agent and performs other shareholder service functions. For these services, Ultimus receives a monthly fee from each Fund at an annual rate of $20 for each direct account and $15 for certain accounts established through financial intermediaries; provided, however, that the minimum monthly fee is $1,000. In addition, the Funds reimburse Ultimus for its out-of-pocket expenses including, but not limited to, postage and supplies. EJV Financial Services, LLC provides certain compliance services to the Funds. Edward J. Veilleux, Vice President and Chief Compliance Officer of the Funds, is also a principal of EJV Financial Services, LLC. 43 - -------------------------------------------------------------------------------- ISI FUNDS - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) NOTE 4 - FEDERAL INCOME TAX AND INVESTMENT TRANSACTIONS The Funds may periodically make reclassifications among certain capital accounts as a result of differences in the characterization and allocation of certain income and capital gain distributions determined annually in accordance with Federal tax regulations, which may differ from U.S. generally accepted accounting principles. These book/tax differences may be either temporary or permanent in nature. To the extent they are permanent, they are charged or credited to paid-in-capital, undistributed net investment income or accumulated net realized gains, as appropriate, in the period that the differences arose. The reclassifications have no impact on the net assets or net asset value per share of the Funds. The Funds determine their net investment income and capital gain distributions in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles. During the periods ended April 30, 2008 and October 31, 2007, the components of distributions on a tax basis were as follows: ORDINARY TAX-EXEMPT LONG-TERM RETURN OF INCOME INCOME CAPITAL GAINS CAPITAL ------------------------ ------------------------ ------------------------ ------------------------ APRIL 30, OCTOBER 31, APRIL 30, OCTOBER 31, APRIL 30, OCTOBER 31, APRIL 30, OCTOBER 31, 2008 2007 2008 2007 2008 2007 2008 2007 Total Return $2,250,582 $4,910,079 $ -- $ -- $ -- $ -- $ -- $ 104,188 Managed Municipal 25,203 72,962 1,856,286 2,371,360 286,768 720,919 -- -- North American 3,560,031 7,026,546 -- -- -- -- -- 172,948 Strategy 470,277 913,710 -- -- 4,220,675 1,880,666 -- -- FASB's Interpretation No. 48 ("FIN 48") "Accounting for Uncertainty in Income Taxes" provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken in the course of preparing each Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be booked as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Recent SEC guidance allows implementing FIN 48 in Fund net asset value calculations as late as the Fund's last such calculation in the first required financial statement reporting period. As a result, the Funds have adopted FIN 48 with this semi-annual report. Based on management's analysis, the adoption of FIN 48 does not have a material impact on the financial statements. The statue of limitations on the Funds' tax returns remains open for the years ended October 31, 2006 and October 31, 2007. 44 - -------------------------------------------------------------------------------- ISI FUNDS - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) As of April 30, 2008, the components of distributable earnings (accumulated losses) on a tax basis were as follows: CAPITAL UNDISTRIBUTED UNDISTRIBUTED UNDISTRIBUTED LOSS UNREALIZED TAX-EXEMPT ORDINARY LONG-TERM CARRY- APPRECIATION INCOME INCOME CAPITAL GAINS FORWARD (DEPRECIATION) TOTAL - ------------------------------------------------------------------------------------------------------------------- Total Return $ -- $ -- $ 220,806 $ -- $ (2,469) $ 218,337 Managed Municipal 148,523 2,795 101,773 -- 2,255,813 2,508,904 North American -- -- 1,111,883 -- 2,000,072 3,111,955 Strategy -- 27,592 -- (250,314) 9,401,791 9,179,069 As of October 31, 2007, Total Return and North American had capital loss carryforwards available to offset future realized gains. These losses expire in 2015. The difference between book and tax basis unrealized appreciation (depreciation) for Strategy was primarily due to wash sales. The aggregate cost of purchases and proceeds from sales of investments, other than short-term obligations, for the six months ended April 30, 2008, were as follows: NON-US GOVERNMENT OBLIGATIONS US GOVERNMENT OBLIGATIONS ----------------------------- ---------------------------- PURCHASES SALES PURCHASES SALES - -------------------------------------------------------------------------------- Total Return $ -- $ -- $ 10,641,250 $ 40,633,085 Managed Municipal 3,458,630 2,040,000 -- -- North American 10,394,227 22,588,662 18,079,063 30,551,211 Strategy 11,377,457 13,321,765 526,294 673,906 NOTE 5 - MARKET AND CREDIT RISK North American invests in Canadian and Mexican government securities. Investing in Canadian and Mexican government securities may have different risks than investing in U.S. government securities. An investment in Canada or Mexico may be affected by developments unique to those countries. These developments may not affect the U.S. economy or the prices of U.S. government securities in the same manner. In addition, the value of bonds issued by non-U.S. governments may be affected by adverse international political and economic developments that may not impact the value of U.S. 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 believe the risk of loss thereunder to be remote. NOTE 7 - OTHER INFORMATION On April 30, 2008, 1 shareholder account held approximately 10% of North American. This shareholder is an omnibus account, which is held on behalf of several individual shareholders. 45 - -------------------------------------------------------------------------------- NOTICE TO SHAREHOLDERS (UNAUDITED) - -------------------------------------------------------------------------------- PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that Strategy uses to determine how to vote proxies relating to securities held in Strategy's portfolio is available, without charge and upon request, by calling (800) 955-7175.
