INVESTMENT ADVISOR'S MESSAGE

- --------------------------------------------------------------------------------

Dear Shareholder:

I am pleased to present the semi-annual report to shareholders of the ISI Funds.
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

(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
      9.0 years.

(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.  Benchmark  returns  do not  reflect  expenses  or sales
      charges that have been deducted from the Fund's returns.


                                                                               3

(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
      sales  charges,  if  applicable.  ISI Class A shares have a maximum  3.00%
      sales charge. ISI Class C Shares have a maximum 1.00% contingent  deferred
      sales charge in the first year, which is eliminated thereafter.

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.

NOTES TO FINANCIAL STATEMENTS
APRIL 30, 2008 (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 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.

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

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.

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:

      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.

      The  difference  between  book  and  tax  basis  unrealized   appreciation

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.
