INVESTMENT ADVISOR'S MESSAGE

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, 2007.
For this period, the Total Return US Treasury Fund, Inc. ('Total Return')
produced a +1.55% return; Managed Municipal Fund, Inc. ('Managed Municipal')
produced a +1.06% return; North American Government Bond Fund, Inc. ('North
American') produced a +1.65% return in its Class A Shares and a +1.32% return
in its Class C Shares; and ISI Strategy Fund ('Strategy') produced a +7.91%
return. These figures assume the reinvestment of dividends and capital gain
distributions, and exclude the impact of any sales charges.

   PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE AND IS NO GUARANTEE OF
FUTURE RESULTS. CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE
DATA QUOTED. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN
INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN ORIGINAL COST.
FOR THE MOST RECENT MONTH-END PERFORMANCE OF A FUND, PLEASE CALL (800) 955-7175.

DESCRIPTION OF FUND OBJECTIVES

   Total Return, Managed Municipal, North American and Strategy, (each a 'Fund'
and collectively, the 'Funds') are registered under the Investment Company Act
of 1940, as amended, as open-end management investment companies. The Funds are
organized as corporations under the laws of the state of Maryland.

   International Strategy & Investment, Inc. ('ISI') manages all four Funds.
Total Return's investment objective is to achieve a high level of total return
with relative stability of principal and, secondarily, high current income
consistent with an investment in securities issued by the United States
Treasury. Managed Municipal's investment objective is designed to provide a
high level of total return with relative stability of principal and,
secondarily, high current income exempt from federal income tax through
investment in a portfolio consisting primarily of tax-free municipal
obligations. North American's investment objective is designed to provide a
high level of current income, consistent with prudent investment risk.
Strategy's investment objective is designed to maximize total return through a
combination of long-term growth of capital and current income.

   We would like to welcome new investors to the ISI Funds and thank those who
have been with us for some time. We appreciate your confidence.

Sincerely,

/s/ R. Alan Medaugh

/1/ PAST PERFORMANCE IS NOT INDICATIVE OF FUTURE RESULTS. Investment return and
    principal value will fluctuate so that an investor's shares, when redeemed,
    may be worth more or less than their original cost. The performance
    information presented in the graph and table above does not reflect the
    deduction of taxes that a shareholder would pay on Fund distributions or
    the redemption of Fund shares. All performance assumes the reinvestment of
    dividends and capital gain distributions and includes the Fund's maximum
    3.00% sales charge. Distribution of the Fund's capital gains and non-US
    Treasury income may be subject to state and local taxes. Management is not
    aware of any single index that is truly representative of the Fund since
    its active maturity management policy allows the manager to adjust the
    weighted average maturity throughout each US Treasury sector. Currently the
    Fund's weighted average maturity is approximately 9.6 years. Performance
    would have been lower during the specified period if certain of the Fund's
    fees and expenses had not been waived.
/2/ The Fund's inception date is August 10, 1988. Benchmark returns are for the
    periods beginning August 31, 1988.
/3/ The Lehman Brothers Treasury Index is an unmanaged index reflecting the
    performance of all public Treasury obligations and does not focus on one
    particular segment of the Treasury market. The Lehman Brothers Intermediate
    Treasury Index is an unmanaged index reflecting the performance of US
    Treasury securities in the intermediate-term Treasury sector. The Lehman
    Brothers Long-Term Treasury Index is an unmanaged index reflecting the
    performance of US Treasury securities in the long-term Treasury sector.
    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
    dividends and capital gain distributions and includes the Fund's maximum
    3.00% sales charge. For certain investors, a portion of the Fund's income
    may be subject to Federal alternative minimum tax. Distribution of the
    Fund's income and capital gains may be subject to state and local taxes.
/2/ The Fund's inception date is February 26, 1990. Benchmark returns are for
    the periods beginning February 28, 1990.
/3/ The Lehman Brothers General Obligation Index is an unmanaged index
    reflecting general municipal market performance. The Lehman Brothers
    Prerefunded Municipal Bond Index, an unmanaged index, is a subcomponent of
    the main Lehman Brothers Municipal Bond Index, and contains only bonds from
    the main index that have been prerefunded or escrowed to maturity.
    Benchmark returns do not reflect expenses or sales charges that have been
    deducted from the Fund's returns.
/4/ The Consumer Price Index is a widely used measure of inflation.

                                                                               3

NORTH AMERICAN GOVERNMENT BOND FUND - ISI CLASS A AND ISI CLASS C SHARES
PERFORMANCE COMPARISON/1/


/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. Performance would have been lower
    during the specified period if certain of the Fund's fees and expenses had
    not been waived.
/2/ ISI Class A Shares inception date is January 15, 1993. Benchmark returns
    are for the periods beginning January 31, 1993.
/3/ ISI Class C Shares inception date is May 16, 2003. Cumulative and
    annualized returns for the Lehman Brothers Intermediate Treasury Index from
    May 31, 2003 through October 31, 2006 were 6.44% and 1.84%, respectively.
/4/ 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.
/5/ Reflects the performance of the Lehman Brothers Emerging Americas Index:
    Mexico Section through October 31, 2004 and the Citigroup US Broad
    Investment-Grade Bond Index Mexico Sector from that date through
    October 31, 2006 and the Lehman Brothers Global Aggregate Index: Mexico
    from October 31, 2006 through April 30, 2007. The Lehman Brothers Emerging
    Americas Index: Mexico Section has been discontinued. Lehman Brothers
    Emerging Americas Index: Mexico Section was an unmanaged sub-index of the
    Lehman Brothers Emerging Americas Index reflecting the performance of
    selected Mexican debt instruments with maturities of one year or more. The
    Citigroup US Broad Investment-Grade Bond Index Mexico Sector is an
    unmanaged sub-index of the Citigroup US Broad Investment-Grade Bond Index
    reflecting the performance of selected Mexican debt instruments with
    maturities of one year or more. The Lehman Brothers Global Aggregate Index:
    Mexico Section is an unmanaged sub-index of the Lehman Brothers Global
    Aggregate Index which provides a broad-based measure of the global
    investment-grade fixed income markets. The Mexican Section reflects the US
    dollar performance of selected Mexican government peso-denominated debt
    instruments with maturities of one year or more. Benchmark returns do not
    reflect expenses or sales charges that have been deducted from the Fund's
    returns.
/6/ The Consumer Price Index is a widely used measure of inflation.

                                                                              5

/1/ PAST PERFORMANCE IS NOT INDICATIVE OF FUTURE RESULTS. Investment return and
    principal value will fluctuate so that an investor's shares, when redeemed,
    may be worth more or less than their original cost. The performance
    information presented in the graph and table above does not reflect the
    deduction of taxes that a shareholder would pay on Fund distributions or
    the redemption of Fund shares. All performance assumes the reinvestment of
    dividends and capital gain distributions and includes the Fund's maximum
    3.00% sales charge. Performance would have been lower during the specified
    period if certain of the Fund's fees and expenses had not been waived.
/2/ The Fund's inception date is September 16, 1997. Benchmark returns are for
    the periods beginning September 30, 1997.
/3/ The Dow Jones Wilshire 5000 (Full Cap) Index is an unmanaged index that
    represents the broadest measure of the US equity market. Benchmark returns
    do not reflect expenses or sales charges that have been deducted from the
    Fund's returns.
/4/ The Consumer Price Index is a widely used measure of inflation.
/5/ Lipper figures represent the average total returns by all the mutual funds
    designated by Lipper, Inc. as falling into the category indicated. The
    Lipper Flexible Portfolio Funds category includes funds that allocate their
    investments across various asset classes, including domestic common stocks,
    bonds and money market instruments with a focus on total return. Benchmark
    returns do not reflect expenses or sales charges that have been deducted
    from the Fund's returns.

SHAREHOLDER EXPENSE EXAMPLE

   As a shareholder of a Fund, you incur two types of costs: (1) transaction
costs for certain share classes, including sales charges (loads) on purchase
payments or other distributions; and (2) ongoing costs, including management
fees, Rule 12b-1 distribution/shareholder service fees for certain share
classes and other Fund expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in a Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

   The following example is based on $1,000 invested on November 1, 2006 and
held for the six months through April 30, 2007.

   ACTUAL EXPENSES - The "Actual Return" rows in the following table provide
information about actual account values and actual expenses. You may use the
information, together with the amount you invested, to estimate the expenses
that you paid over the period. Simply divide your account value by $1,000 (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply the
result by the number in the "Expenses Paid During Period" column to estimate
the expenses you paid on your account during this period.

   HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES - The "Hypothetical Return"
rows in the following table provide information about hypothetical account
values and hypothetical expenses based on each Fund's actual expense ratio and
an assumed rate of return of 5% per year before expenses, which is not the
actual return of each Fund. The hypothetical account values and expenses may
not be used to estimate the actual ending account balance or expenses you paid
for the period. You may use this information to compare the ongoing cost of
investing in a Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder
reports of other funds.

   Expenses shown in the table are meant to highlight your ongoing costs only
and do not reflect any transactional costs, such as sales charges (loads).
Therefore, the "Hypothetical Return" rows in the table are useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. If these transactional costs were included, your costs
would have been higher.

                                                                              7

ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

A. ORGANIZATION

  Total Return US Treasury Fund, Inc. ('Total Return'), Managed Municipal Fund,
Inc. ('Managed Municipal'), North American Government Bond Fund, Inc. ('North
American') and ISI Strategy Fund, Inc. ('Strategy'), (each a 'Fund' and
collectively, the 'Funds') are registered under the Investment Company Act of
1940, as amended, as open-end management investment companies. The Funds are
organized as corporations under the laws of the State of Maryland.

  Total Return's investment objective is to achieve a high level of total
return with relative stability of principal and, secondarily, high current
income consistent with an investment in securities issued by the United States
Treasury. Managed Municipal's investment objective is to provide a high level
of total return with relative stability of principal and, secondarily, high
current income exempt from Federal income tax through investment in a portfolio
consisting primarily of tax-free municipal obligations. North American's
investment objective is designed to provide a high level of current income,
consistent with prudent investment risk. Strategy's investment objective is to
maximize total return through a combination of long-term growth of capital and
current income.

  Total Return, Managed Municipal and Strategy currently offer ISI Shares to
investors. North American offers ISI North American Government Bond Fund
Class A Shares ('ISI Class A Shares') and ISI North American Government Bond
Fund Class C Shares ('ISI Class C Shares'). ISI Shares and North American's ISI
Class A Shares are subject to a maximum front-end sales charge of 3.00%. A
contingent deferred sales charge of 1.00% is imposed on the sale of North
American's ISI Class C Shares if redeemed within the first year after purchase.

  Total Return, Managed Municipal and Strategy are authorized to issue
115,000,000, 55,000,000 and 25,000,000 shares, respectively, of ISI Shares at
$0.001 par value. North American is authorized to issue 50,000,000 ISI Class A
Shares and 5,000,000 ISI Class C Shares at $0.001 par value.

B. VALUATION OF SECURITIES

  Exchange traded securities and over-the-counter securities listed on the
NASDAQ National Market System for which market quotations are readily available
are valued each Fund business day using the last reported sales price or the
NASDAQ Official Closing Price ('NOCP'), provided by independent pricing
services as of the close of trading on the New York Stock Exchange (normally
4:00 p.m. Eastern time). In the absence of a sale or NOCP, such securities are
valued at the mean of the last bid and the last asked prices. Non-exchange
traded securities for which over-the-counter quotations are readily available
are generally valued at the mean between the last bid and last asked prices.
Money market instruments that mature in 60 days or less may be valued at
amortized cost unless the Fund's investment advisor believes another valuation
is more appropriate.

  When valuing securities for which market quotations are not readily available
or for which the market quotations that are available are considered
unreliable, the Funds determine a fair value in good faith under procedures
established by and under the general supervision of the Funds' Boards of
Directors (the 'Board'). The Funds may use these procedures to establish the
fair value of securities when, for example, a significant event occurs between
the time the market closes and the time as of which the Funds value their
investments if such an event is likely to affect the Fund's net asset value per
share. Fair valuation may also be used for securities that are subject to legal
or contractual restrictions on resale, securities for which no or limited
trading activity has occurred for a period of time, or securities that are
otherwise deemed to be illiquid (i.e., securities that cannot be disposed of
within seven days at approximately the price at which the security is currently
priced by the Funds).

34




ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED)


  If a fair value is required, the investment advisor or sub-advisor in the
case of Strategy, determines the value of the security until the Board meets to
establish the fair value of the security.

  As of April 30, 2007, there were no fair valued securities.

C. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

  Securities transactions are recorded on trade date. Realized gains and losses
are determined by comparing the proceeds of a sale or the cost of a purchase
with a specific offsetting transaction. Dividend income is recorded on the
ex-dividend date. Interest income, including amortization of premiums and
accretion of discounts, is accrued daily. Estimated expenses are also accrued
daily. With respect to North American, income, gains (losses) and common
expenses are allocated to each class based on its respective net assets. Class
specific expenses are charged directly to each class.

D. DISTRIBUTIONS

  Total Return declares a dividend daily, and Managed Municipal and North
American declare monthly dividends at fixed rates approved by the Funds' Board.
These dividends are paid monthly. To the extent that their net investment
income and short-term capital gains are less than the approved fixed rate, some
of their dividends may be paid from long-term capital gains or as a return of
shareholder capital. Strategy declares and pays dividends quarterly from its
net investment income. Net realized capital gains, if any, are distributed at
least annually. The Funds record dividends and distributions on the ex-dividend
date.

  A return of capital may occur for North American at October 31, 2007. The
exact amount, if any, is undeterminable at this time.

E. FEDERAL INCOME TAXES

  Each Fund has a policy to qualify as a regulated investment company under
subchapter M of the Internal Revenue Code and to distribute all its taxable
income. In addition, by distributing in each calendar year substantially all of
its net income, capital gains and other amounts, if any, the Funds will not be
subject to Federal excise taxes. Accordingly, no Federal income taxes have been
accrued.

F. FOREIGN CURRENCY TRANSLATION

  The Funds maintain their accounting records in US dollars. North American
determines the US dollar value of foreign currency-denominated assets,
liabilities and transactions by using prevailing exchange rates. In valuing
assets and liabilities, North American uses the prevailing exchange rate on
valuation date. In valuing security transactions, the receipt of income and the
payment of expenses, North American uses the prevailing exchange rate on the
transaction date.

  Net realized gains and losses on foreign currency transactions shown on North
American's financial statements result from the sale of foreign bonds and
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and from the difference between
the amounts of interest recorded on the Fund's books and the US dollar
equivalent of the amounts actually received or paid.

G. FORWARD FOREIGN CURRENCY CONTRACTS

  North American may use forward foreign currency contracts to manage foreign
exchange rate risk. The Fund may use these contracts to fix the US dollar value
of securities transactions for the period between the date of the transaction
and the date the security is received or delivered or to hedge the US dollar
value of securities that it already owns. The use of forward foreign currency
contracts does not eliminate fluctuations in the prices of the underlying
securities, but does establish a rate of exchange that can be achieved in the
future.

  The Fund determines the net US dollar value of forward foreign currency
contracts using prevailing exchange rates. As of April 30, 2007, there were no
open forward currency contracts.

                                                                             35




ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED)


H. REPURCHASE AGREEMENTS

  The Funds may make short-term investments in repurchase agreements that are
fully collateralized by US government securities. Under the terms of a
repurchase agreement, a financial institution sells fixed-income securities to
the Funds and agrees to buy them back on a specified day in return for the
principal amount of the original sale plus accrued interest. The custodial bank
holds the collateral in a separate account until the agreement matures. If the
value of the securities falls below the principal amount of the repurchase
agreement plus accrued interest, the financial institution deposits additional
collateral by the following business day. If the financial institution either
fails to deposit the required additional collateral or fails to repurchase the
securities as agreed, the Funds have the right to sell the securities and
recover any resulting loss from the financial institution. If the financial
institution enters into bankruptcy, the Funds' claims on the collateral may be
subject to legal proceedings.

I. ESTIMATES

  In preparing its financial statements in conformity with US generally
accepted accounting principles, management makes estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the period. Actual results
may be different.

NOTE 2 - NEW ACCOUNTING PRONOUNCEMENTS

  In June 2006, the Financial Accounting Standards Board ("FASB") issued
Financial Interpretation No. 48, "Accounting for Uncertainty in Income Taxes"
(the "Interpretation") which is effective for fiscal years beginning after
December 15, 2006, and is to be applied to all open tax years as of the
effective date. This Interpretation prescribes a minimum threshold for
financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded
disclosures. Management has recently begun to evaluate the application of the
Interpretation, and has not at this time determined the impact, if any,
resulting from its adoption on the Fund's financial statements.

  In September 2006, the FASB issued Statement of Financial Accounting
Standards No. 157 "Fair Value Measurements" (the "Statement") which is
effective for fiscal years beginning after November 15, 2007 and interim
periods within those fiscal years. This Statement defines fair value,
establishes a framework for measuring fair value in generally accepted
accounting principles, and expands disclosures about fair value measurements.
Management has recently begun to evaluate the application of the Statement, and
has not at this time determined the impact, if any, resulting from its adoption
on the Fund's financial statements.

NOTE 3 - FEES AND TRANSACTIONS WITH AFFILIATES AND OTHER SERVICE PROVIDERS

  International Strategy & Investment, Inc. ('ISI') is the Funds' 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 an annual fee based on its average
daily net assets, which is calculated daily and paid monthly at the annual rate
of 0.40%.

  ISI has contractually agreed to waive its fees and/or reimburse expenses of
North American through February 28, 2008, to the extent necessary, to limit the
expenses of ISI Class C Shares to 1.85% of the class' average daily net assets.
For the six months ended April 30, 2007, there were no fees waived.

  Los Angeles Capital Management and Equity Research, Inc. ('LA Capital
Management') is Strategy's

ISI FUNDS NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

Sub-Advisor and is responsible for managing the common stocks in the Fund's
portfolio. The Sub-Advisor is paid by ISI, not the Fund.

  The Northern Trust Company is the Funds' Custodian.

  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. For the six months
ended April 30, 2007, North American Class A Shares did not pay any shareholder
servicing fees.

  For the six months ended April 30, 2007, ISI Group earned commissions on
sales of ISI Shares of Total Return, Managed Municipal, and Strategy of $959,
$1,807 and $10,396, respectively, and $5,926 on sales of ISI Class A Shares of
North American. ISI Group retained $430 of the back-end sales charges on the
sale of ISI Class C Shares of North American.

  EJV Financial Services, LLC ("EJV") provides certain compliance support
services to the Fund's Chief Compliance Officer. Edward J. Veilleux, Vice
President of the Funds is also a principal of EJV.

  Citigroup Fund Services, LLC ('Citigroup') serves as the Funds'
Administrator, Accountant, and Transfer Agent. For its services, Citigroup
receives a combined fee based on the aggregate average net assets of the Funds
(subject to a minimum monthly fee) and monthly fees per open shareholder
account. Average net asset-based fees are calculated daily and all fees are
paid monthly.

NOTE 4 - FEDERAL INCOME TAX AND INVESTMENT TRANSACTIONS

  The Funds determine their net investment income and capital gain
distributions in accordance with income tax regulations, which may differ from
US generally accepted accounting principles.

  As of October 31, 2006, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:



- ------------------------------------------------------------------------------------------------------
                  Undistributed                 Undistributed                Unrealized

North American             -              -               -            -     (3,703,499)   (3,703,499)

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


  The difference between book basis and tax basis unrealized appreciation
(depreciation) for Strategy was primarily due to wash sales.

                                                                             37

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 US government securities. An investment in Canada or
Mexico may be affected by developments unique to those countries. These
developments may not affect the US economy or the prices of US government
securities in the same manner. In addition, the value of bonds issued by non-US
governments may be affected by adverse international political and economic
developments that may not impact the value of US government securities.

NOTE 6 - CONTRACTUAL OBLIGATIONS

  In the ordinary course of business, the Funds enter into contracts that
contain a variety of indemnifications. Each Fund's maximum exposure under these
arrangements is unknown. However, the Funds have not had prior claims or losses
pursuant to these indemnification provisions and expect the risk of loss
thereunder to be remote.

NOTE 7 - OTHER INFORMATION

  On April 30, 2007, one shareholder held approximately 12% of the outstanding
shares of North American. This shareholder is an omnibus account, which is held
on behalf of several individual shareholders.

NOTE 8 - PROXY VOTING INFORMATION

  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

Fund's proxy voting record for the 12-month period ended June 30, 2006 is

NOTE 9 - AVAILABILITY OF QUARTERLY PORTFOLIO SCHEDULE

the operation of the Public Reference Room may be obtained by

NOTE 10 - CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

  Effective December 14, 2005, the Funds replaced Ernst & Young LLP ("E & Y")
with Briggs Bunting & Dougherty, LLP as the Funds' independent registered
public accounting firm by action of the Funds' Board of Directors and upon the
recommendation of the Audit and Compliance Committee of the Board. E & Y's
reports on each Fund's financial statements for the fiscal years ended October
31, 2004 and October 31, 2005 contained no adverse opinion or disclaimer of
opinion nor were they qualified or modified as to the uncertainty, audit scope,
or accounting principles.

  During the Fund's fiscal years ended October 31, 2004 and October 31, 2005,
(i) there were no disagreements with E & Y on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure, which disagreements, if not resolved to the satisfaction of E & Y,
would have caused it to make reference to the subject matter of disagreements
in connection with its report on each Fund's financial statements for such
year, and (ii) there were no "reportable events" of the kind described in Item
304 (a) (1) (v) of Regulation S-K under the Securities Exchange Act of 1934, as
amended.
