Investment Advisor’s Message 4/30/2011

Dear Shareholder:

I am pleased to present the semi-annual report to shareholders for the ISI Funds. This report covers the six-month reporting period ended April 30, 2011. For this period, the Total Return US Treasury Fund, Inc. (‘Total Return’) produced a -2.46% return; Managed Municipal Fund, Inc. (‘Managed Municipal’) produced a -1.05% return in its Class A Shares and a -0.83 return in its Class I Shares; North American Government Bond Fund, Inc. (‘North American’) produced a -0.13% return in its Class A Shares, a -0.37% return in its Class C Shares, and a +0.15% return in its Class I Shares; and ISI Strategy Fund (‘Strategy’) produced a +13.72% 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) 882-8585.

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,

R. Alan Medaugh

President

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. Distributions 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 6.51 years.
2	The Fund’s inception date is August 10, 1988. Benchmark returns are for the periods beginning August 31, 1988.
3	The Barclays Capital 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 Barclays Capital Intermediate Treasury Index is an unmanaged index reflecting the performance of US Treasury securities in the intermediate-term Treasury sector. The Barclays Capital Long-Term Treasury Index is an unmanaged index reflecting the performance of US Treasury securities in the long-term Treasury sector. Benchmark returns do not reflect expenses or sales charges that have been deducted from the Fund’s returns.

Shareholder Expense Examples (Unaudited)

As a shareholder of the Funds, you may incur two types of cost; (1) transaction costs, 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 (November 1, 2010) and held for the entire period (April 30, 2011).

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 costs 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.

*	Non-income producing security.

Gross Unrealized Appreciation	$	16,754,146
Gross Unrealized Depreciation		(1,698,124	)
Net Unrealized Appreciation	$	15,056,022

The difference between the federal income tax cost of portfolio investments and the Schedule of Investments cost is due to certain timing differences in the recognition of capital gains and losses under income tax regulations and accounting principles generally accepted in the United States. These timing differences are temporary in nature and are due to the tax deferral of losses on wash sales.

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 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 and Strategy each currently offer a single class of shares (ISI Shares) to investors. Managed Municipal offers two classes of shares – ISI Class A Shares and ISI Class I Shares. North American offers three classes of shares – ISI Class A Shares, ISI Class C Shares and ISI Class I 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 of purchase.

Total Return and Strategy are authorized to issue 115,000,000 and 25,000,000 shares, respectively, of ISI Shares at $0.001 par value. Managed Municipal is authorized to issue 50,000,000 ISI Class A Shares and 5,000,000 ISI Class I Shares at $0.001 par value. North American is authorized to issue 50,000,000 ISI Class A Shares, 5,000,000 ISI Class C Shares and 5,000,000 ISI Class I 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

46

ISI Funds

Notes to Financial Statements (continued)

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. Debt securities may be valued at prices supplied by a Fund’s pricing agent based on broker or dealer supplied valuations or matrix pricing, a method of valuing securities by reference to the value of other securities with similar characteristics such as rating, interest rate, and maturity. 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 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, 2011, there were no fair valued securities.

Accounting principles generally accepted in the United States (“GAAP”) establish a single authoritative definition of fair value, set out a frame work for measuring fair value and require additional disclosures about fair value measurements.

Various inputs are used in determining the value of each Fund’s investments. These inputs are summarized in the three broad levels listed below:

Level 1 – quoted prices in active markets for identical securities

Level 2 – other significant observable inputs

Level 3 – significant unobservable inputs

The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

See Strategy’s Schedule of Investments for a listing of the common stocks valued using Level 1 inputs by industry type.

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 and

48

ISI Funds

Notes to Financial Statements (continued)

Managed Municipal, 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 distributions daily, and North American declares monthly distributions at fixed rates approved by the Board. These distributions are paid monthly. To the extent that a Fund’s net investment income is less than an approved fixed rate, some of its distributions may be designated as a return of 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. As provided therein in any fiscal year in which a Fund so qualifies and distributes at least 90% of its net taxable income, the Fund (but not its shareholders) will be relieved of Federal income tax on the income distributed. 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 or excise taxes have been accrued.

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 in 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 in the net change in unrealized appreciation/depreciation on investments.

49

ISI Funds

Notes to Financial Statements (continued)

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.

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 U.S. government 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.

I.  Estimates

In preparing its financial statements in conformity with GAAP, 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 – Fees and Transactions with Affiliates

International Strategy & Investment, Inc. (“ISI”) is the Funds’ investment advisor. As compensation for ISI’s 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. As compensation for ISI’s advisory services, 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.

50

ISI Funds

Notes to Financial Statements (continued)

ISI has contractually agreed to reimburse expenses with respect to Class C Shares of North American through February 29, 2012 to the extent necessary to limit the annual ordinary operating 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, 2011, ISI was not required to 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.

International Strategy & Investment Group, Inc. (“ISI Group”), an affiliate of ISI, is the distributor for the Funds. Total Return, Managed Municipal (ISI Class A Shares, only) 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 of 0.25% of 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 rates of 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, 2011, ISI Group earned commissions on sales of ISI Shares of Total Return, Managed Municipal and Strategy of $1,657, $3,474 and $3,121, respectively, and earned commissions of $2,451 on sales of ISI Class A Shares of North American. ISI Group retained $1,932 of contingent deferred sales charges on redemptions of ISI Class C Shares of North American during the six months ended April 30, 2011.

State Street Bank and Trust Company (“State Street”) is the administrator of the Funds. State Street is responsible for providing certain administrative services to the Funds, and assists in managing and supervising all aspects of the general day-to-day business activities and operations of the Fund other than investment advisory activities, including maintaining the books and records of the Fund, and preparing certain reports and other documents required by federal and/or state laws and regulations. For the performance of these services, the Funds pay State Street an annual fee of $300,000. This fee is allocated among the Funds based on the relative net assets of each Fund.

State Street is the fund accountant and fund custodian, and State Street is responsible for safeguarding and controlling the Funds’ cash and securities, handling the delivery of securities and collecting interest and dividends on the Fund’s investments. State Street as fund accounting agent is responsible for maintaining the books and records and calculating the daily net asset value of the Fund. For Fund accounting services, the Funds pay State Street an annual base fee of $180,000. For Fund custodian services, the Funds pay State Street an annual base fee of 1 (one) basis point on net assets, plus other asset-based fees that vary according to the number of positions and transactions, plus out-of-pocket fees.

51

ISI Funds

Notes to Financial Statements (continued)

State Street also serves as transfer agent for the Funds and is responsible for the issuance, transfer and redemption of shares and the opening, maintenance and servicing of shareholder accounts. For these services State Street receives an annual amount of $65,000, allocated among the Funds based on the relative net assets of each Fund and 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. In addition, the Funds reimburse State Street for its out-of-pocket expenses including, but not limited to, postage and supplies.

EJV Financial Services, LLC (“EJV”) 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. The Funds pay EJV $18,750 quarterly for providing CCO services. This fee is allocated among the Funds based on the relative net assets of each Fund. In addition, the Funds reimburse EJV for any reasonable out-of-pocket expenses relating to these compliance services.

The Funds pay each independent Director an annual fee of $15,000. The Audit Committee Chairman and Chairman of the Board receive an annual fee of $17,000 and $19,000 respectively. In addition each independent Director receives $1,000 for each Board meeting attended. The Funds also reimburse each of the Directors for out-of-pocket expenses incurred in connection with attending the Board of Directors’ meetings. Certain officers of the Funds are also officers or employees of the above named service providers, and during their terms of office, receive no compensation from the Funds.

Note 3 – Federal Income Tax

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 GAAP. 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 GAAP.

During the periods ended April 30, 2011 and October 31, 2010, the tax character of distributions paid by each of the Funds was as follows:

Strategy		399,163	*		809,407		—		—		—		—

* A portion of the ordinary income is short-term gains that are taxed as ordinary income for tax purposes. However, these short-term gains may be offset by losses incurred through October 31, 2011 and therefore could be treated as return of capital.

The Funds recognize the tax benefits or expenses of uncertain tax positions only when the position is “more likely than not” to be sustained assuming examination by tax authorities. Management has reviewed each Fund’s tax positions taken on Federal and state income tax returns for all open tax years (tax years ended October 31, 2007 through October 31, 2010) and concluded that no provision for unrecognized tax benefits or expenses is required in these financial statements.

As of October 31, 2010, the components of distributable earnings (accumulated deficit) on a tax basis were as follows:

	Total Return			Managed Municipal			North American			Strategy
Undistributed ordinary income	$	76,573		$	126,576		$	314,696		$	9,755
Undistributed tax-exempt income		—			102,319			—			—

Total	$	4,430,783		$	5,177,366		$	6,137,132		$	3,698,733

As of October 31, 2010, Strategy had capital loss carryforwards of $5,592,059, of which $989,548 expires October 31, 2016, $4,076,771 expires October 31, 2017, and $525,740 expires October 31, 2018. These capital loss carryforwards may be utilized in the current and future years to offset net realized capital gains, if any, prior to distributing such gains to shareholders.

Notes to Financial Statements (continued)

The difference between the federal income tax cost of portfolio investments and the financial statement cost for Strategy is due to certain timing differences in the recognition of capital gains or losses under income tax reporting regulations and GAAP. These “book/tax” differences are temporary in nature and are primarily due to the tax deferral of losses on wash sales.

Note 4 – Investment Transactions

The aggregate cost of purchases and proceeds from sales of investments, other than short-term obligations, for the six months ended April 30, 2011 were as follows:

	Non-US Government Obligations				US Government Obligations
	Purchases		Sales		Purchases		Sales
Total Return	$	—	$	—	$	11,008,594	$	12,201,484
Managed Municipal		4,298,955		8,094,380		—		—
North American		—		11,817,763		23,920,652		12,568,281
Strategy		17,562,765		13,678,628		800,625		890,297

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 – Recent Accounting Pronouncement

In January 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2010-06 “Improving Disclosures about Fair Value Measurements.” ASU No. 2010-06 amends FASB Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, to require additional disclosures regarding fair value measurements. Certain disclosures required by ASU No.

Notes to Financial Statements (continued)

2010-06 are effective for interim and annual reporting periods beginning after December 31, 2009 and others for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. Management is currently evaluating the impact ASU No. 2010-06 will have on the Funds’ financial statement disclosures and has determined no disclosure is necessary, other than is noted below.

Note 8 – Subsequent Events

GAAP requires the Funds to recognize in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed as of the date of the Statements of Assets and Liabilities. For non-recognized subsequent events that must be disclosed to keep the financial statements from being misleading, the Funds are required to disclose the nature of the event as well as an estimate of its financial effect, or a statement that such an estimate cannot be made. Management has evaluated subsequent events through the issuance of these financial statements and has determined no disclosure is necessary other than is noted below.

On May 31, 2011 North American Class A Shares, Class C Shares, and Class I Shares, Managed Municipal Class A Shares and Class I Shares, and Total Return ISI Shares paid a distribution of $0.016, $0.013, $0.018, $0.0226, $0.0248, and $0.015, respectively, per share in net investment income related to the period ended May 31, 2011.
