INVESTMENT ADVISOR'S REPORT:
- --------------------------------------------------------------------------------


Dear Shareholder:

     I am pleased to present the Semi-Annual  report to shareholders for the ISI
Funds.  This report  consolidates  the four funds into one  report.  This report
covers the six month reporting period ended April 30, 2003. For this period, the
Total Return US Treasury Fund, Inc. (`Total  Return')  produced a +2.80% return;
Managed  Municipal Fund, Inc.  (`Managed  Municipal')  produced a +3.50% return;
North American  Government Bond Fund, Inc. (`North American')  produced a +3.79%
return; and Strategy Fund (`Strategy')  produced a +3.96% return.  These figures
assume the reinvestment of dividend and capital gain distributions,  and exclude
the impact of any sales charges.

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 (the 'Act'), as amended, as open-end  management  investment
companies.  The Funds are organized as corporations  under the laws of the state
of Maryland.

     ISI  manages all four Funds for total  return  through  active  management.
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.

RECENT FUND EVENTS

     Effective October 31, 2002, North American changed its fiscal year end from
March 31 to October 31 and  Strategy  changed its fiscal year end from May 31 to
October 31. Total Return and Managed  Municipal already had an October 31 fiscal
year end.  These  changes to North  American and Strategy gave us the ability to
produce a combined annual and semi-annual report.

     For the six month reporting  period ended April 30, 2003, The Funds offered
only one class of shares to  investors:  ISI  Shares.  On May 16, 2003 the North
American  Fund  started  offering C Shares,  and the  existing  ISI Shares  were
redesignated as A Shares.

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
     dividend  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 10.7 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  obligations and does not focus on one particular
     segment of the Treasury  market.  The Lehman  Brothers  Long-Term  Treasury
     Index is an  unmanaged  index  reflecting  the  performance  of US Treasury
     securities  in  the  long-term   Treasury   sector.   The  Lehman  Brothers
     Intermediate   Treasury  Index  is  an  unmanaged   index   reflecting  the
     performance  of US Treasury  securities in the  intermediate-term  Treasury
     sector.  Benchmark  returns do not reflect  expenses or sales  charges that
     have been deducted from the Fund's returns.

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
     dividend 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.  For
     certain  investors,  a portion of the  Fund's  income may be subject to the
     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  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.  The Lehman Brothers  General  Obligation Index is an
     unmanaged index reflecting general municipal market performance. 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.

1    Past Performance is not indicative of future results. Investment return and
     principal 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 dividend and
     capital gain  distributions  and includes  the Fund's  maximum  3.00% sales
     charge.  Performance  does  not  reflect  the  deduction  of  taxes  that a
     shareholder  would pay on a fund  distribution  or the  redemption  of fund
     shares.  Performance  would have been lower during the specified periods if
     certain of the Fund's fees and expenses had not been waived.
2    The Fund's  inception date is January 15, 1993.  Benchmark  returns are for
     the periods beginning January 31, 1993.
3    The Lehman  Brothers  Intermediate  Treasury  Index is an  unmanaged  index
     reflecting   the   performance   of   US   Treasury   securities   in   the
     intermediate-term Treasury sector.
4    Lehman Brothers  Emerging  Americas  Index:  Mexico Section is an unmanaged
     sub-index of the Lehman  Brothers  Emerging  Markets Index  reflecting  the
     performance of selected  Mexican debt  instruments  with  maturities of one
     year or more. The  performance  information in the graph and table above is
     quoted in US dollars. Benchmark  returns do not reflect  expenses or sales
     charges that have been deducted from the Fund's returns.
5    The Consumer Price Index is a widely used measure of inflation.

1    PAST PERFORMANCE IS NOT INDICATIVE OF FUTURE RESULTS. Investment return and
     principal 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 dividend 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 Wilshire 5000 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  reported by all the
     mutual  funds  designated  by Lipper,  Inc.  as falling  into the  category
     indicated.

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 Strategy  Fund,  Inc.  (`Strategy'),  (each a `Fund' and
collectively,  the `Funds') are registered  under the Investment  Company Act of
1940 (the `Act'), 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 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.

     Effective October 31, 2002, North American changed its fiscal year end from
March 31 to October 31 and  Strategy  changed its fiscal year end from May 31 to
October 31.

     The Funds currently offer one class of shares to investors: ISI Shares. ISI
Shares in Total  Return,  Managed  Municipal,  North  American  and Strategy are
subject to a maximum  front-end  sales  charge of 3.00%.  Prior to February  28,
2002, Total Return and Managed Municipal offered Deutsche Asset Management Class
A Shares  (`Class A Shares') to  investors.  On February 28,  2002,  the Class A
Shares  were merged into the ISI  Shares.  On May 16, 2003 North  American  Fund
started offering C Shares and ISI Shares were redesigned as A Shares.

B.       VALUATION OF SECURITIES

         The Funds value their investments at market value.

         When valuing fixed income securities,  the Funds use the last bid price
prior to the  calculation of the Funds' net asset value.  If a current bid price
is not available, the Funds use the mean between the latest quoted bid and asked
prices.

         When valuing  listed  equity  securities,  Strategy  uses the last sale
price prior to the  calculation  of its net asset  value.  When  valuing  equity
securities that are not listed or that are listed but have not traded,  the Fund
use the bid price in the over-the-counter market.

         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'  Board  of
Directors.  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  the  Funds  value  their   investments.   After
consideration  of various  factors,  the Funds may value the securities at their
last reported price or at fair value. On April 30, 2003 Strategy had fair valued
securities,   which  are  footnoted   accordingly  in  the  Fund's  schedule  of
investments.

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.


                                                                              39



- --------------------------------------------------------------------------------
ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED-CONTINUED)
- --------------------------------------------------------------------------------

Estimated  expenses are also accrued  daily.  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 pays a daily  dividend  and,  Managed  Municipal and North
American  pay  monthly  dividends  at  rates  approved  by the  Funds'  Board of
Directors. To the extent that their net investment income and short-term capital
gains are less than the approved  rate, the Funds may pay some of their dividend
from  long-term  capital gains or as a return of shareholder  capital.  Strategy
pays  dividends  quarterly  from its net  investment  income and  annually  from
capital  gains.  An  additional  distribution  of net  realized  short-term  and
long-term capital gains earned by the Funds, if any, may be made annually to the
extent they exceed capital loss  carryforwards.  The Funds record  dividends and
distributions on the ex-dividend date

E.    FEDERAL INCOME TAXES

     The Funds each have a policy to qualify as a regulated investment companies
under the Internal  Revenue Code and to  distribute  substantially  all of their
taxable income to shareholders.  Accordingly,  no federal income taxes have been
accrued.

     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  accounting  principals
generally accepted in the United States.  These book/tax  differences are either
temporary or permanent in nature. To the extent these differences are permanent,
they are charged or credited to paid-in-capital or accumulated net realized gain
as appropriate, in the period that the differences arise.

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,
foreign  currencies,  currency  gains or losses  realized  between the trade and
settlement  dates on securities  transactions,  and the  difference  between the
amounts of interest  recorded on its 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 a securities  transaction  for the period between the date of the transaction
and the date of the  security is received  or  delivered  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. On April 30, 2003 there were no open
forward currency contracts.

ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED-CONTINUED)
- --------------------------------------------------------------------------------

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  accounting
principles  generally accepted in the United States,  management makes estimates
and assumptions. Actual results may be different.

Note 4 - 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 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  international
organizations  may be affected by adverse  international  political and economic
developments that may not impact the value of US government securities.


                                                                              43
