Nuveen High Yield Municipal Bond Fund

Fund Overview

Investment Objectives

The investment objective of the fund is to provide high current income exempt
from regular federal income taxes. Capital appreciation is a secondary
objective when consistent with the fund's primary objective.

How the Fund Pursues Its Objectives

The fund invests substantially all of its assets in municipal bonds. Under
normal circumstances, the adviser invests at least 65% of the fund's net assets
in medium-to low-quality bonds (BBB/Baa or lower) as rated by Standard & Poor's,
Moody's Investors Service, Duff & Phelps, or Fitch IBCA, Inc, or if unrated,
judged to be of comparable quality. The fund may invest up to 10% of its net
assets in defaulted municipal bonds. The fund may buy securities that pay
interest at rates that float inversely with changes in prevailing interest
rates. The fund may also make forward commitments in which the fund agrees to
buy a security in the future at a price agreed upon today.

The fund's investment adviser uses a research-intensive investment process to
identify high-yielding municipal bonds that offer attractive value in terms of
their current yields, prices, credit quality, liquidity and future prospects.

What are the Risks of Investing in the Fund?

An investment in the fund is subject to credit risk, interest rate risk and
diversification risk. Credit risk is the risk that a municipal bond issuer will
default or be unable to pay principal and interest. Because the fund invests in
lower rated municipal bonds, commonly referred to as "high yield," "high risk"
or "junk" bonds, which are considered to be speculative, the credit risk is
heighten ed for the fund. Interest rate risk is the risk that interest rates
will rise, causing municipal bond prices to fall. Interest rate risk may be
increased by the fund's investment in inverse floating rate securities and
forward commitments because of the leveraged nature of these investments. As a
"non-diversified" fund, the fund may invest more of its assets in a single
issuer than a "diversified" fund. Greater concentration may increase the
variability of the fund's net asset value. As with any mutual fund investment,
loss of money is a risk of investing.

Is This Fund Right for You?

The fund may be appropriate for you if you are seeking to:

  . earn monthly tax-free dividends; or
  . increase your after-tax income potential and are willing to accept a greater
    degree of risk.

You should not invest in this fund if you are seeking to:

  . avoid share price fluctuation;

  . avoid the risks associated with low-quality municipal bonds; or
  . invest through an IRA or 401(k) plan.

How the Fund Has Performed

The fund does not have a performance history for a full calendar year.

The Benefits of High Yield Municipal Bond Funds
-----------------------------------------------

As interest rates have declined over the past several years, municipal high
yield bond funds have provided higher taxable-equivalent yields and more income
than funds investing in higher-rated corporate and U.S. Treasury bonds (see
chart below). The information in the chart below gives some indication of the
difference in yield among high yield municipal bond funds, like the fund,
A-rated corporate bond funds and U.S. treasury bond funds. For investors
comfortable bearing greater risk in pursuing higher yield, high yield municipal
bond funds can be an important source of additional income in your portfolio.

High yield municipal bond funds, A-rated corporate bond funds and general U.S.
treasury bond funds are represented by the Lipper High-Yield Municipal Debt
Funds Index, Lipper A-Rated Corporate Bond Index and the Lipper General U.S.
Treasury Bond Index, respectively. The distribution yield of the High-Yield
Municipal Bond Funds is computed on a taxable-equivalent basis assuming a 31%
tax rate. A taxable equivalent yield is the current yield you would need to earn
on a taxable investment to equal a stated tax-free yield on a municipal
investment. High-yield municipal bonds carry a greater risk of default than
either A-rated corporate bonds or U.S. treasury bonds. U.S. treasury bonds are
backed by the U.S. government and thus carry a minimal amount of credit risk.
The chart above does not present taxable-equivalent yields for U.S. treasury
bonds, which are exempt from state income taxes, since the tax benefit varies
across states and is modest in most states. The high yield municipal bond fund
yields shown do not represent the past performance or predict the future yields
of the fund.

Nuveen All-American Municipal Bond Fund

Fund Overview

Investment Objective

The investment objective of the fund is to provide you with as high a level of
current interest income exempt from regular federal income taxes as is
consistent with preservation of capital.

How the Fund Pursues Its Objective

The fund purchases only quality municipal bonds that are rated investment grade
(AAA/Aaa to BBB/Baa) at the time of purchase by independent rating agencies.
The fund may buy non-rated municipal bonds if the fund's investment adviser
judges them to be investment grade.

The fund's investment adviser uses a value-oriented strategy and looks for
higher-yielding and undervalued long-term municipal bonds that offer potentially
above-average total return.

The fund seeks to limit risk by buying investment grade quality bonds in a
variety of industry sectors and by diversifying its investment portfolio
geographically.

What are the Risks of Investing in the Fund?

The principal risks of investing in the fund are interest rate risk and credit
risk. Interest rate risk is the risk that interest rates will rise, causing
bond prices to fall. Credit risk is the risk that an issuer of a municipal bond
will be unable to make interest and principal payments. In general, lower rated
municipal bonds carry greater credit risk. As with any mutual fund investment,
loss of money is a risk of investing.

Is This Fund Right For You?

The fund may be a suitable investment for you if you seek to:

  . Earn regular monthly tax-free dividends;
  . Preserve investment capital over time;

  . Reduce taxes on investment income; or
  . Set aside money systematically for retirement, estate planning or college
    funding.

You should not invest in this fund if you seek to:

  . Pursue long-term growth;
  . Invest through an IRA or 401(k) plan; or
  . Avoid fluctuations in share price.

How the Fund Has Performed

The chart and table below illustrate annual fund returns for each of the past
ten years as well as annualized fund and index returns for the one-, five- and
ten-year periods ending December 31, 1999. This information is intended to help
you assess the variability of fund returns over the past ten years (and
consequently, the potential rewards and risks of a fund investment). Past
performance is not necessarily an indication of future performance.

consistent with preservation of capital.

How the Fund Pursues Its Objective

The fund purchases only quality municipal bonds that are rated investment grade
(AAA/Aaa to BBB/Baa) at the time of purchase by independent rating agencies. The
fund may buy non-rated municipal bonds if the fund's investment adviser judges
them to be investment grade.

The fund's investment adviser uses a value-oriented strategy and looks for
higher-yielding and undervalued municipal bonds that offer potentially above-
average total return. The adviser invests in a diversified portfolio of
investment-grade quality bonds of various maturities with a weighted average
duration of between three and ten years. The adviser intends to maintain
portfolio duration within a defined range (currently between 4.5 and seven
years) over time in order to be classified as an intermediate fund.

The fund seeks to limit risk by buying investment grade quality bonds in a
variety of industry sectors and by diversifying its invest ment portfolio
geographically.

What are the Risks of Investing in the Fund?

The principal risks of investing in the fund are interest rate risk and credit
risk. Interest rate risk is the risk that interest rates will rise, causing
bond prices to fall. Credit risk is the risk that an issuer of a municipal bond
will be unable to make interest and principal payments. In general, lower rated
municipal bonds carry greater credit risk. As with any mutual fund investment,
loss of money is a risk of investing.

Is This Fund Right For You?

The fund may be a suitable investment for you if you seek to:

 .  Earn regular monthly tax-free dividends;
 .  Preserve investment capital over time;

 .  Reduce taxes on investment income; or
 .  Set aside money systematically for retirement, estate planning or college
   funding.

You should not invest in this fund if you seek to:

 .  Pursue long-term growth;
 .  Invest through an IRA or 401(k) plan; or
 .  Avoid fluctuations in share price.


How the Fund Has Performed

The chart and table below illustrate annual fund returns for each of the past
ten years as well as annualized fund and index returns for the one-, five- and
ten-year periods ending December 31, 1999. This information is intended to help
you assess the variability of fund returns over the past ten years (and
consequently, the potential rewards and risks of a fund investment). Past
performance is not necessarily an indication of future performance.

Nuveen Intermediate Municipal Bond Fund

Fund Overview


See "Introduction - Proposed Merger" for important information regarding the
fund.

Investment Objective

The investment objective of the fund is to provide you with as high a level of
current interest income exempt from regular federal income taxes as is
consistent with preservation of capital.

How the Fund Pursues Its Objective

The fund purchases only quality municipal bonds that are rated investment grade
(AAA/Aaa to BBB/Baa) at the time of purchase by independent rating agencies.
The fund may buy non-rated municipal bonds if the fund's investment adviser
judges them to be investment grade.

The fund's investment adviser uses a value-oriented strategy and looks for
higher-yielding and undervalued intermediate-term municipal bonds that offer
potentially above-average total return.

The fund seeks to limit risk by buying investment grade quality bonds in a
variety of industry sectors and by diversifying its investment portfolio
geographically.

What are the Risks of Investing in the Fund?

The principal risks of investing in the fund are interest rate risk and credit
risk. Interest rate risk is the risk that interest rates will rise, causing
bond prices to fall. Credit risk is the risk that an issuer of a municipal bond
will be unable to make interest and principal payments. In general, lower rated
municipal bonds carry greater credit risk. As with any mutual fund investment,
loss of money is a risk of investing.

Is This Fund Right For You?

The fund may be a suitable investment for you if you seek to:
  .  Earn regular monthly tax-free dividends;
  .  Preserve investment capital over time;
  .  Reduce taxes on investment income; or
  .  Set aside money systematically for retirement, estate planning or college
     funding.

You should not invest in this fund if you seek to:
  .  Pursue long-term growth;
  .  Invest through an IRA or 401(k) plan; or
  .  Avoid fluctuations in share price.

How the Fund Has Performed


The chart and table below illustrate annual fund returns for each of the past
seven years as well as annualized fund and index returns for the one- and five-
year and since inception periods ending December 31, 1999. This information is
intended to help you assess the variability of fund returns over the past seven
years (and consequently, the potential rewards and risks of a fund investment).
Past performance is not necessarily an indication of future performance.

Nuveen Limited Term Municipal Bond Fund

Fund Overview

Investment Objective

The investment objective of the fund is to provide you with as high a level of
current interest income exempt from regular federal income taxes as is
consistent with preservation of capital.

How the Fund Pursues Its Objective

The fund purchases only quality municipal bonds that are rated investment grade
(AAA/Aaa to BBB/Baa) at the time of purchase by independent rating agencies.
The fund may buy non-rated municipal bonds if the fund's investment adviser
judges them to be investment grade.

The fund's investment adviser uses a value-oriented strategy and looks for
higher-yielding and undervalued limited-term municipal bonds that offer
potentially above-average total return.

The fund seeks to limit risk by buying investment grade quality bonds in a
variety of industry sectors and by diversifying its investment portfolio
geographically.

What are the Risks of Investing in the Fund?

The principal risks of investing in the fund are interest rate risk and credit
risk. Interest rate risk is the risk that interest rates will rise, causing
bond prices to fall. Credit risk is the risk that an issuer of a municipal bond
will be unable to make interest and principal payments. In general, lower rated
municipal bonds may carry greater credit risk. As with any mutual fund
investment, loss of money is a risk of investing.

Is This Fund Right For You?

The fund may be a suitable investment for you if you seek to:

    .    Earn regular monthly tax-free dividends;
    .    Preserve investment capital over time;
    .    Reduce taxes on investment income; or
    .    Set aside money systematically for retirement, estate planning or
         college funding.

You should not invest in this fund if you seek to:

    .    Pursue long-term growth;

    .    Invest through an IRA or 401(k) plan; or
    .    Avoid fluctuations in share price.

How the Fund Has Performed

The chart and table below illustrate annual fund returns for each of the past
ten years as well as annualized fund and index returns for the one-, five- and
ten-year periods ending December 31, 1999. This information is intended to help
you assess the variability of fund returns over the past ten years (and
consequently, the potential rewards and risks of a fund investment). Past
performance is not necessarily an indication of future performance.

What Securities We Invest In


Each fund's investment objective may not be changed without shareholder
approval. The following investment policies may be changed by the Board of
Trustees without shareholder approval unless otherwise noted in this prospectus
or the Statement of Additional Information.

Municipal Bonds

The funds invest primarily in municipal bonds that pay interest that is exempt
from regular federal income tax. Income from these bonds may be subject to the
federal alternative minimum tax.

States, local governments and municipalities issue municipal bonds to raise
money for various public purposes such as building public facilities,
refinancing outstanding obligations and financing general operating expenses.
These bonds include general obligation bonds, which are backed

                                         Section 2  How We Manage Your Money  15
<PAGE>

by the full faith and credit of the issuer and may be repaid from any revenue
source, and revenue bonds, which may be repaid only from the revenue of a
specific facility or source.

The funds may purchase municipal bonds that represent lease obligations. These
carry special risks because the issuer of the bonds may not be obligated to
appropriate money annually to make payments under the lease. In order to reduce
this risk, the funds will only purchase these bonds where the issuer has a
strong incentive to continue making appropriations until maturity.

In evaluating municipal bonds of different credit qualities or maturities,
Nuveen Advisory takes into account the size of yield spreads. Yield spread is
the additional return the funds may earn by taking on additional credit risk or
interest rate risk. For example, yields on low quality bonds are higher than
yields on high quality bonds because investors must be compensated for incurring
the higher credit risk associated with low quality bonds. If yield spreads do
not provide adequate compensation for the additional risk associated with low
quality bonds, the funds will buy bonds of relatively higher quality. Similarly,
in evaluating bonds of different maturities, Nuveen Advisory evaluates the
comparative yield available on these bonds. If yield spreads on long-term bonds
do not compensate the funds adequately for the additional interest rate risk the
funds must assume, the funds will buy bonds of relatively shorter maturity. In
addition, municipal bonds in a particular industry may provide higher yields
relative to their risk compared to bonds in other industries. If that occurs, a
fund may buy relatively more bonds from issuers in that industry. In that case,
the fund's portfolio composition would change from time to time.

Credit Quality

The All-American, Insured, Intermediate Duration, Intermediate and Limited Term
Funds purchase only quality municipal bonds that are either rated investment
grade (AAA/Aaa to BBB/Baa) by independent rating agencies at the time of
purchase or are non-rated but judged to be investment grade by Nuveen Advisory.
Each such fund, except the Insured Fund, will invest at least 80% of its net
assets in investment-grade quality municipal bonds. The Insured Fund will
invest at least 65% of its net assets in insured municipal bonds, and will
invest at least 80% of its net assets in municipal bonds that are either insured
or backed by U.S. Government securities.

High Yield Fund. Under normal circumstances, at least 65% of the High Yield
Fund's net assets will be invested in medium- to low-quality municipal bonds
rated BBB/Baa or lower by Standard & Poor's, Moody's Investors Service, Duff &
Phelps, or Fitch IBCA, Inc., or if unrated, judged by Nuveen Advisory to be of
comparable quality. The High Yield Fund may invest up to 10% of its net assets
in defaulted municipal bonds. "Defaulted" means that the bond's issuer has not
paid principal or interest on time. Municipal bonds that are rated below
investment grade (BB/Ba or lower) are commonly known as "high yield," "high
risk" or "junk" bonds. They typically offer higher yields but involve greater
risks, including the possibility of default or bankruptcy, and increased market
price volatility.

The High Yield Fund may invest in higher quality municipal bonds (those rated
AAA/Aaa to A or, if unrated, judged by Nuveen Advisory to be of

16  Section 2  How We Manage Your Money
<PAGE>


comparable quality) or in short-term, high-quality investments. The High Yield
Fund may do this as a temporary defensive measure, in response to unusual market
conditions, when there is a lack of acceptable lower rated bonds or at times
when yield spreads do not justify the increased risks of investing in lower
rated bonds. If the High Yield Fund invests in higher quality municipal bonds,
it may not be able to achieve its investment objectives.

Portfolio Maturity and Duration

Each fund buys municipal bonds with different maturities in pursuit of its
investment objectives, but maintains under normal market conditions an
investment portfolio with an overall weighted average maturity within a defined
range. The Limited Term Fund maintains a weighted average portfolio maturity of
1 to 7 years. The Intermediate Fund maintains a weighted average portfolio
maturity of 5 to 10 years. The High Yield, Insured and All-American Funds are
long-term funds and normally maintain a weighted average portfolio maturity of
15 to 30 years.

The Intermediate Duration Fund maintains a weighted average portfolio duration
of 3 to 10 years. Maturity measures the time until a bond makes its final
payment. Duration measures the bond's expected life on a present value basis,
taking into account the bond's yield, interest payments and final maturity.
Duration is a reasonably accurate measure of a bond's price sensitivity to
changes in interest rates. The longer the duration of a bond, the greater the
bond's price sensitivity is to changes in interest rates. The adviser intends to
maintain the Intermediate Duration Fund's duration within a defined range
(currently between 4.5 and 7 years) over time in order to be classified as an
intermediate fund.

Inverse Floating Rate Securities

Each fund may invest up to 15% of its total assets in municipal securities whose
coupons vary inversely with changes in short-term tax-exempt interest rates and
which thus are a leveraged investment in an underlying municipal bond (or
securities with similar economic characteristics). These securities present
special risks for two reasons: (1) if short-term interest rates rise (fall), the
income the fund earns on the inverse floating rate security will fall (rise);
and (2) if long-term interest rates rise (fall), the value of the inverse
floating rate security will fall (rise) more than the value of the underlying
bond because of the leveraged nature of the investment. These securities
generally are illiquid. The funds will seek to buy these securities at
attractive values and yields that more than compensate the funds for their
higher income and price volatility and reduced liquidity.

Forwards and Delayed-Delivery Settlement

Each fund may enter into contracts to purchase securities for a specified price
at a future date later than the normal settlement date. If the delayed
settlement takes place less than 61 days after purchase, it is referred to as a
"delayed-delivery" transaction. Newly issued municipal bonds sold on a "when-
issued" basis represent a common form of delayed-delivery transaction. If
settlement takes place more than 60 days after purchase, the transaction is
called a "forward." These transactions involve an element of risk because the
value of the security to be purchased may decline before the settlement
date.


                                         Section 2  How We Manage Your Money  17
<PAGE>


Municipal "forwards" pay higher interest rates after settlement than standard
bonds, to compensate the buyer for bearing market risk but deferring income
during the settlement period, and can often be bought at attractive prices and
yields. If a fund knows that a portfolio bond will, or is likely to, be called
or mature on a specific future date, the fund may buy a forward settling on or
about that date to replace the called or maturing bond and "lock in" a currently
attractive interest rate. Also, the High Yield Fund may invest up to 15% of its
assets in forwards that do not serve to replace a specific bond.

Insurance (Insured Fund)

The Insured Fund primarily purchases insured municipal bonds. Insured municipal
bonds are either covered by individual, permanent insurance policies (obtained
either at the time of issuance or subsequently) or covered "while in fund" under
a master portfolio insurance policy purchased by a fund. Insurance guarantees
only the timely payment of interest and principal on the bonds; it does not
guarantee the value of either individual bonds or fund shares.

Portfolio insurance policies are effective only so long as the Insured Fund
continues to own the covered bond, and the price the fund would receive upon
sale of such a bond would not benefit from the insurance. Insurers under master
portfolio insurance policies currently include MBIA Insurance Corp., Ambac
Assurance Corporation, Financial Security Assurance, Inc. and Financial Guaranty
Insurance Company. The Insured Fund's investment adviser may obtain master
policies from other insurers, but only from insurers that specialize in insuring
municipal bonds and whose claims-paying ability is rated Aaa or AAA by Moody's
or S&P. Insurers are responsible for making their own assessment of the
insurability of a municipal bond.

The Insured Fund can invest up to 20% of its net assets in uninsured municipal
bonds that are backed by an escrow containing sufficient U.S. Government or
U.S. Government agency securities to ensure timely payment of principal and
interest. These bonds are normally regarded as having the credit characteristics
of the underlying U.S. Government-backed securities.

Short-Term Investments

Under normal market conditions, each fund may invest up to 20% of net assets in
short-term, high quality municipal bonds. See "How We Manage Risk--Hedging and
Other Defensive Investment Strategies." The funds may invest in short-term, high
quality taxable securities if suitable short-term municipal bonds are not
available at reasonable prices and yields. If the funds invest in taxable
securities, they may not achieve their investment objective. For more
information on eligible short-term investments, see the Statement of Additional
Information.

How We Select Investments

Nuveen Advisory selects municipal bonds for the funds based upon its assessment
of a bond's relative value in terms of current yield, price, credit quality and
future prospects. Nuveen Advisory is supported by Nuveen's award-winning team of
specialized research analysts who review municipal securities available for
purchase, monitor the continued creditworthiness of


18  Section 2  How We Manage Your Money
<PAGE>

each fund's municipal investments, and analyze economic, political and
demographic trends affecting the municipal markets. We utilize these resources
to identify municipal bonds with favorable characteristics we believe are not
yet recognized by the market. We then select those higher-yielding and
undervalued municipal bonds that we believe represent the most attractive
values.

Portfolio Turnover

A fund buys and sells portfolio securities in the normal course of its
investment activities. The proportion of the fund's investment portfolio that is
sold and replaced with new securities during a year is known as the fund's
portfolio turnover rate. The funds intend to keep portfolio turnover relatively
low in order to reduce trading costs and the realization of taxable capital
gains. Each fund, however, may make limited short-term trades to take advantage
of market opportunities or reduce market risk.

What the Risks Are

Risk is inherent in all investing. Investing in a mutual fund -- even the most
conservative -- involves risk, including the risk that you may receive little or
no return on your investment or even that you may lose part or all of your
investment. Therefore, before investing you should consider carefully the
following risks that you assume when you invest in these funds. Because of
these and other risks, you should consider an investment in any of these funds
to be a long-term investment.

Credit risk: Each fund is subject to credit risk. Credit risk is the risk that
an issuer of a municipal bond will be unable to meet its obligation to make
interest and principal payments due to changing financial or market conditions.
Credit risk is higher for the High Yield Fund because it invests in lower-rated
municipal bonds.

Interest rate risk: Because the funds invest in fixed-income securities, the
funds are subject to interest rate risk. Interest rate risk is the risk that
the value of a fund's portfolio will decline because of rising interest rates.
Interest rate risk is generally lower for shorter-term investments and higher
for longer-term investments.

Income risk: The risk that the income from a fund's portfolio will decline
because of falling market interest rates. This can result when the fund invests
the proceeds from new share sales, or from matured or called bonds, at market
interest rates that are below the portfolio's current earnings rate. Also, if a
fund invests in inverse floating rate securities, whose income payments vary
inversely with changes in short-term market rates, the fund's income may
decrease if short-term interest rates rise.

Inflation risk: The risk that the value of assets or income from investments
will be less in the future as inflation decreases the value of money. As
inflation increases, the value of the fund's assets can decline as can the value
of the fund's distributions.


                                         Section 2  How We Manage Your Money  19

<PAGE>

How We Manage Risk

In pursuit of its investment objectives, each fund assumes investment risk,
chiefly in the form of interest rate and credit risk. The funds limit this
investment risk generally by restricting the type and maturities of municipal
bonds they purchase, and by diversifying their investment portfolios
geographically as well as across different industry sectors.

The Insured Fund also limits investment risk by primarily buying insured
municipal bonds.

Investment Limitations

The funds have adopted certain investment limitations (based on total assets)
that cannot be changed without shareholder approval and are designed to limit
your investment risk and maintain portfolio diversification. Each fund may not
have more than:

 .    5% in securities of any one issuer (except for U.S. Government securities
     or for 25% of each fund's total assets). This limitation does not apply to
     the High Yield Fund.

 .    25% in any one industry such as electric utilities or health care.

 .    10% in borrowings (33% if used to meet redemptions).

Hedging and Other Defensive Investment Strategies

Each fund may invest up to 100% in cash equivalents and short-term investments
as a temporary defensive measure in response to adverse market conditions, or to
keep cash on hand fully invested. During these periods, the weighted average
maturity of a fund's investment portfolio may fall below the defined range
described under "Portfolio Maturity."

Each fund may also use various investment strategies designed to limit the risk
of bond price fluctuations and to preserve capital. These hedging strategies
include using financial futures contracts, options on financial futures, or
options based on either an index of long-term tax-free securities or on debt
securities whose prices, in Nuveen Advisory's opinion, correlate with the prices
of the funds' investments. The funds, however, have no present intent to use
these strategies.

Section 3  How You Can Buy and Sell Shares

We offer four classes of fund shares, each with a different combination of sales
charges, fees, eligibility requirements and other features. Your financial
advisor can help you determine which class is best for you. We offer a number of
services for your convenience. Please see the Statement of Additional
Information for further details.

What Share Classes We Offer

Class A Shares

You can buy Class A shares at the offering price, which is the net asset value
per share plus an up-front sales charge. You may qualify for a reduced sales
charge, or the sales charge may be waived, as described in "How to Reduce Your
Sales Charge." Class A shares are also subject to an annual service fee of .20%
which compensates your financial advisor for providing ongoing service to you.
Nuveen retains the up-front sales charge and the service fee on accounts with
no authorized dealer of record. The up-front Class A sales charge for the
Intermediate Duration, Insured, High Yield and All-American Funds is as follows:

1. You can buy $1 million or more of Class A shares at net asset value without
an up-front sales charge. Nuveen pays authorized dealers of record on these
share purchases a sales commission of 1.00% (0.75% and 0.50%, respectively, for
the Intermediate and Limited Term funds) of the first $2.5 million, plus .50% of
the next $2.5 million, plus .25% (0.50% for the Intermediate Fund) of the amount
over $5.0 million. If you redeem your shares within 18 months of purchase, you
may have to pay a Contingent Deferred Sales Charge ("CDSC") of 1% (0.75% and
0.50%, respectively, for the Intermediate and Limited Term funds) of either your
purchase price or your redemption proceeds, whichever is lower. You do not have
to pay this CDSC if your financial advisor has made arrangements with Nuveen and
agrees to waive the commission.

Class B Shares

You can buy Class B shares at the offering price, which is the net asset value
per share without any up-front sales charge so that the full amount of your
purchase is invested in the fund. However, you will pay annual distribution and
service fees of .95% of average daily assets. The annual .20% service fee
compensates your financial advisor for providing ongoing service to you. Nuveen
retains the service and distribution fees on accounts with no authorized dealer
of record. The annual .75% distribution fee compensates Nuveen for paying your
financial advisor a 4% up-front sales commission, which includes an advance of
the first year's service fee. If you sell your shares within six years of
purchase, you will normally have to pay a CDSC based on either your purchase
price or what you sell your shares for, whichever amount is lower, according to
the following schedule. You do not pay a CDSC on any Class B shares you purchase
by reinvesting dividends. The Intermediate Fund and the Limited Term Fund do not
currently offer Class B shares.

Class B shares automatically convert to Class A shares eight years after you buy
them so that the distribution fees you pay over the life of your investment are
limited. You will continue to pay an annual service fee on any converted Class B
shares.

Class C Shares

You can buy Class C shares at the offering price, which is the net asset value

service fees of .75% (.55% for the Limited Term Fund). The annual .20% service
fee compensates your financial advisor for providing ongoing service to you.
Nuveen retains the service and distribution fees on accounts with no authorized
dealer of record. The annual .55% (.35% for the Limited Term Fund) distribution
fee reimburses Nuveen for paying your

financial advisor an ongoing sales commission. Nuveen advances the first year's
service and distribution fees. If you sell your shares within 12 months of
purchase, you will normally have to pay a 1% CDSC based on your purchase or sale
price, whichever is lower. You do not pay a CDSC on any Class C shares you
purchase by reinvesting dividends.

Class R Shares

You may purchase Class R shares only under limited circumstances, at the
offering price, which is the net asset value on the day of purchase. In order
to qualify, you must be eligible under one of the programs described in "How to
Reduce Your Sales Charge" (below) or meet certain other purchase size criteria.
Class R shares are not subject to sales charges or ongoing service or
distribution fees. Class R shares have lower ongoing expenses than the other
classes.

How to Reduce Your Sales Charge

We offer a number of ways to reduce or eliminate the up-front sales charge on
Class A shares or to qualify to purchase Class R shares.

Class A Sales Charge Reductions
 . Rights of accumulation
 . Letter of intent
 . Group purchase

Class A Sales Charge Waivers
 . Nuveen Defined Portfolio or Exchange-Traded Fund reinvestment
 . Certain employees and directors of Nuveen or employees of authorized dealers
 . Bank trust departments

Class R Eligibility
 . Certain employees and directors of Nuveen or employees of authorized dealers
 . Bank trust departments


In addition, Class A shares at net asset value and Class R shares may be
purchased through registered investment advisers, certified financial planners
and registered broker-dealers who charge asset-based or comprehensive "wrap"
fees for their services. Please refer to the Statement of Additional Information
for detailed program descriptions and eligibility requirements. Additional
information is available from your financial adviser or by calling (800) 257-
8787. Your financial advisor can also help you prepare any necessary application
forms. You or your financial advisor must notify Nuveen at the time of each
purchase if you are eligible for any of these programs. The funds may modify or
discontinue these programs at any time.

How to Buy Shares

Fund shares may be purchased on any business day, which is any day the New York
Stock Exchange is open for business and normally ends at 4 p.m. New York time.
Generally, the Exchange is closed on weekends and national holidays. The share
price you pay will depend on when Nuveen receives your order. Orders received
before the close of trading on a business day will receive that day's closing
share price, otherwise you will receive the next business day's price.

                                  Section 3  How You Can Buy and Sell Shares  23
<PAGE>


Through a Financial Advisor

You may buy shares through your financial advisor, who can handle all the
details for you, including opening a new account. Financial advisors can also
help you review your financial needs and formulate long-term investment goals
and objectives. In addition, financial advisors generally can help you develop a
customized financial plan, select investments and monitor and review your
portfolio on an on-going basis to help assure your investments continue to meet
your needs as circumstances change. Financial advisors are paid for on-going
investment advice and services either from fund sales charges and fees or by
charging you a separate fee in lieu of a sales charge. If you do not have a
financial advisor, call (800) 257-8787 and Nuveen can refer you to one in your
area.

By Mail

You may open an account and buy shares by mail by completing the enclosed
application and mailing it along with your check to: Nuveen Investor Services,
P.O. Box 5186, Bowling Green Station, New York, NY 10274-5186. No third party
checks will be accepted.

Investment Minimums

The minimum initial investment is $3,000 ($50 through systematic investment plan
accounts) and may be lower for accounts opened through certain fee-based
programs. Subsequent investments must be in amounts of $50 or more. The funds
reserve the right to reject purchase orders and to waive or increase the
minimum investment requirements.

Systematic Investing

Systematic investing allows you to make regular investments through automatic
deductions from your bank account, directly from your paycheck, or by
exchanging shares from another mutual fund account. The minimum automatic
deduction is $50 per month. There is no charge to participate in each fund's
systematic investment plan. You can stop the deductions at any time by notifying
the fund in writing. To participate in systematic investing, simply complete
the appropriate section of the account application form or submit an Account
Update Form.

From Your Bank Account

You can make systematic investments of $50 or more per month by authorizing us
to draw preauthorized checks on your bank account.

From Your Paycheck

With your employer's consent, you can make systematic investments of $25 or more
per pay period (meeting the monthly minimum of $50) by authorizing your employer
to deduct monies from your paycheck.

Systematic Exchanging

You can make systematic investments by authorizing Nuveen to exchange shares
from one Nuveen mutual fund account into another identically registered Nuveen
account of the same share class.

24  Section 3  How You Can Buy and Sell Shares
<PAGE>

The chart below illustrates the benefits of systematic investing based on a
$3,000 initial investment and subsequent monthly investments of $100 over 20
years. The example assumes you earn a return of 4%, 5% or 6% annually on your
investment and that you reinvest all dividends. These annual returns do not
reflect past or projected fund performance.

                             [GRAPH APPEARS HERE]

                             [PLOT POINTS TO COME]

Invested Principal     Compounded 4%     Compounded 5%     Compounded 6%

One of the benefits of systematic investing is dollar cost averaging. Because
you regularly invest a fixed amount of money over a period of years regardless
of the share price, you buy more shares when the price is low and fewer shares
when the price is high. As a result, the average share price you pay should be
less than the average share price of fund shares over the same period. To be
effective, dollar cost averaging requires that you invest over a long period of
time, and does not assure that you will profit.

Systematic Withdrawal

If the value of your fund account is at least $10,000, you may request to have
$50 or more withdrawn automatically from your account. You may elect to receive
payments monthly, quarterly, semi-annually or annually, and may choose to
receive a check, have the monies transferred directly into your bank account
(see "Special Services--Fund Direct" below), paid to a third party or sent
payable to you at an address other than your address of record. You must
complete the appropriate section of the account application or Account Update
Form to participate in the fund's systematic withdrawal plan.

You should not establish systematic withdrawals if you intend to make concurrent
purchases of Class A, B or C shares because you may unnecessarily pay a sales
charge or CDSC on these purchases.

Special Services

To help make your investing with us easy and efficient, we offer you the
following services at no extra cost.

Exchanging Shares

You may exchange fund shares into an identically registered account at any time
for an appropriate class of another Nuveen mutual fund available in your state.
Your exchange must meet the minimum purchase requirements of the fund into which
you are exchanging. You may have to pay a sales charge when exchanging shares
that you purchased without a sales charge for shares that are sold with a sales
charge. Please consult the Statement of Additional Information for details.

The exchange privilege is not intended to allow you to use a fund for short-term
trading. Because excessive exchanges may interfere with portfolio management,
raise fund operating expenses or otherwise have an adverse effect on other
shareholders, each fund reserves the right to revise or suspend the exchange
privilege, limit the amount or number of exchanges, or reject any exchange.

The funds may change or cancel their exchange policy at any time upon 60 days'
notice. Because an exchange is treated for tax purposes as a purchase and sale,
and any gain may be subject to tax, you should consult your tax advisor about
the tax consequences of exchanging your shares.

Fund Direct/SM/

The Fund Direct Program allows you to link your fund account to your bank
account, transfer money electronically between these accounts, and perform a
variety of account transactions, including purchasing shares by telephone and
investing through a systematic investment plan. You also may have dividends,
distributions, redemption payments or systematic withdrawal plan payments sent
directly to your bank account. Your financial advisor can help you complete the
forms for these services, or you can call Nuveen at (800) 257-8787 for copies of
the necessary forms.

Reinstatement Privilege

If you redeem fund shares, you may reinvest all or part of your redemption
proceeds up to one year later without incurring any additional charges. You may
only reinvest into the same share class you redeemed. If you paid a CDSC, we
will refund your CDSC and reinstate your holding period. You may use this
reinstatement privilege only once for any redemption.

How to Sell Shares

You may sell (redeem) your shares on any business day. You will receive the
share price next determined after Nuveen has received your properly completed
redemption request. Your redemption request must be received before the close of
trading for you to receive that day's price. If you are selling shares purchased
recently with a check, you will not receive your redemption proceeds until your
check has cleared. This may take up to ten business days from your purchase
date. While the funds do not charge a redemption fee, you may be assessed a
CDSC, if applicable. When you redeem Class A, Class B, or Class C shares subject
to a CDSC, the fund will first redeem any shares that are not subject to a
CDSC, and then redeem the shares you have owned for the longest period of time,
unless you ask the fund to redeem your shares in a different order. No CDSC is
imposed on shares you buy through the reinvestment of dividends and capital

<PAGE>

gains. The holding period is calculated on a monthly basis and begins on the
first day of the month in which you buy shares. When you redeem shares subject
to a CDSC, the CDSC is calculated on the lower of your purchase price or
redemption proceeds, deducted from your redemption proceeds, and paid to
Nuveen. The CDSC may be waived under certain special circumstances as described
in the Statement of Additional Information.


Through Your Financial Advisor

You may sell your shares through your financial advisor who can prepare the
necessary documentation. Your financial advisor may charge for this.

By Telephone

If you have authorized telephone redemption privileges, you can redeem your
shares by calling (800) 257-8787. Telephone redemptions are not available if
you own shares in certificate form and may not exceed $50,000. Checks will only
be issued to you as the shareholder of record and mailed to your address of
record. If you have established Fund Direct privileges, you may have redemption
proceeds transferred electronically to your bank account. We will normally mail
your check the next business day.

An Important Note About Telephone Transactions

Although Nuveen Investor Services has certain safeguards and procedures to
confirm the identity of callers, it will not be liable for losses resulting from
following telephone instructions it reasonably believes to be genuine. Also you
should verify your trade confirmations immediately upon receipt.

By Mail

You can sell your shares at any time by sending a written request to the
appropriate fund, c/o Nuveen Investor Services, P.O. Box 5186, Bowling Green
Station, New York, NY 10274-5186. Your request must include the following
information:

 . The fund's name;

 . Your name and account number;

 . The dollar or share amount you wish to redeem;

 . The signature of each owner exactly as it appears on the account;

 . The name of the person to whom you want your redemption proceeds paid (if
  other than to the shareholder of record);

 . The address where you want your redemption proceeds sent (if other than the
  address of record);

 . Any certificates you have for the shares; and

 . Any required signature guarantees.

We will normally mail your check the next business day, but in no event more
than seven days after we receive your request. If you purchased your shares by
check, your redemption proceeds will not be mailed until your check has cleared.
Guaranteed signatures are required if you are redeeming more than $50,000, you
want the check payable to someone other than the shareholder of record or you
want the check sent to another address (or the address of record has been
changed within the last 60 days). Signature guarantees must be obtained from a
bank, brokerage firm or other financial intermediary that is a member of an
approved Medallion Guarantee Program or that is otherwise approved by a fund. A
notary public cannot provide a signature guarantee.

Redemptions In-Kind

The funds generally pay redemption proceeds in cash. Under unusual conditions
that make cash payment unwise and for the protection of existing shareholders,
the funds may pay all or a portion of your redemption proceeds in securities or
other fund assets. Although it is unlikely that your shares would be redeemed
in-kind, you would probably have to pay brokerage costs to sell the securities
distributed to you, as well as taxes on any capital gains from that sale.

An Important Note About Involuntary Redemption

From time to time, the funds may establish minimum account size requirements.
The funds reserve the right to liquidate your account upon 30 days' written
notice if the value of your account falls below an established minimum. The
funds presently have set a minimum balance of $100 unless you have an active
Nuveen Defined Portfolio reinvestment account. You will not be assessed a CDSC
on an involuntary redemption.

Section 4  General Information

To help you understand the tax implications of investing in the funds, this
section includes important details about how the funds make distributions to
shareholders. We discuss some other fund policies, as well.

Dividends, Distributions and Taxes

The funds pay tax-free dividends monthly. If the funds realize capital gains or
ordinary income subject to regular federal income tax, the funds will pay any
taxable capital gains or other taxable distributions once a year in December.
The funds declare dividends monthly to shareholders of record as of the ninth of
each month, usually payable the first business day of the following month.

Payment and Reinvestment Options

The funds automatically reinvest your dividends in additional fund shares unless
you request otherwise. You may request to have your dividends paid to you by
check, deposited directly into your bank account, paid to a third party, sent to
an address other than your address of record or reinvested in shares of another
Nuveen mutual fund. For further information, contact your financial advisor or
call Nuveen at (800) 257-8787.

Taxes and Tax Reporting

Because the funds invest primarily in municipal bonds, the regular monthly
dividends you receive will be exempt from regular federal income tax. All or a
portion of these dividends, however, may be subject to state and local taxes or
to the federal alternative minimum tax (AMT).

Although the funds do not seek to realize taxable income or capital gains, the
funds may realize and distribute taxable income or capital gains from time to
time as a result of the funds' normal investment activities. The funds'
distributions of these amounts are taxed as ordinary income or capital gains
(which may be taxable at different rates depending on the length of time the
fund holds its assets). Dividends from the funds' long-term capital gains are
taxable as capital gains, while dividends from short-term capital gains and net
investment income are generally taxable as ordinary income. The tax you pay on a
capital gains distribution depends generally on how long the fund has held the
portfolio securities it sold. It does not depend on how long you have owned your
fund shares. Taxable dividends do not qualify for a dividends received deduction
if you are a corporate shareholder.

Early in each year, you will receive a statement detailing the amount and nature
of all dividends and capital gains that you were paid during the prior year. If
you hold your investment at the firm where you purchased your fund shares, you
will receive the statement from that firm. If you hold your shares directly at
the fund, Nuveen will send you the statement. The tax status of your dividends
is not affected by whether you reinvest your dividends or elect to receive them
in cash.


28  Section 4  General Information
<PAGE>

If you receive social security or railroad retirement benefits, you should
consult your tax advisor about how an investment in the fund may affect the
federal taxation of your benefits.

Please note that if you do not furnish us with your correct Social Security
number or employer identification number, federal law requires the fund to
withhold federal income tax from your distributions and redemption proceeds,
currently at a rate of 31%.

Please consult the Statement of Additional Information and your tax advisor for
more information about taxes.


Buying or Selling Shares Close to a Record Date

Buying fund shares shortly before the record date for a taxable dividend is
commonly known as "buying the dividend." The entire dividend may be taxable to
you even though a portion of the dividend effectively represents a return of
your purchase price. Similarly, if you sell or exchange fund shares shortly
before the record date for a tax-exempt dividend, a portion of the price you
receive may be treated as a taxable capital gain even though it reflects tax-
free income earned but not yet distributed by the fund.


Taxable Equivalent Yields

The taxable equivalent yield is the current yield you would need to earn on a
taxable investment in order to equal a stated federal tax-free yield on a
municipal investment. To assist you to more easily compare municipal investments
like the funds with taxable alternative investments, the table below presents
the taxable equivalent yields for a range of hypothetical federal tax-free
yields and tax rates:


Taxable Equivalent Of Tax-Free Yields

                To Equal a Tax-Free Yield of:
--------------------------------------------------------------------------------
                4.00%       4.50%       5.00%       5.50%       6.00%

Tax Bracket:    A Taxable Investment Would Need to Yield:
--------------------------------------------------------------------------------
   28.0%        5.56%       6.25%       6.94%       7.64%       8.33%
--------------------------------------------------------------------------------
   31.0%        5.80%       6.52%       7.25%       7.97%       8.70%
--------------------------------------------------------------------------------
   36.0%        6.25%       7.03%       7.81%       8.59%       9.37%
--------------------------------------------------------------------------------
   39.6%        6.62%       7.45%       8.28%       9.11%       9.93%
--------------------------------------------------------------------------------

The yields and tax rates shown above are hypothetical and do not predict your
actual returns or effective tax rate. For more detailed information, see the
Statement of Additional Information or consult your tax advisor.


Distribution and Service Plans

Nuveen serves as the selling agent and distributor of the funds' shares. In this
capacity, Nuveen manages the offering of the funds' shares and is responsible
for all sales and promotional activities. In order to reimburse Nuveen for its
costs in connection with these activities, including compensation paid to
authorized dealers, each fund has adopted a distribution and service plan under
Rule 12b-1 under the Investment Company Act of 1940. (See "How to Choose a Share
Class" for a description of the distribution and service fees paid under this
plan.)

Nuveen receives the distribution fee for Class B and Class C shares primarily
for providing compensation to authorized dealers, including

                                              Section 4  General Information  29
<PAGE>

Nuveen, in connection with the distribution of shares. Nuveen uses the service
fee for Class A, Class B, and Class C shares to compensate authorized dealers,
including Nuveen, for providing on-going account services to shareholders. These
services may include establishing and maintaining shareholder accounts,
answering shareholder inquiries, and providing other personal services to
shareholders. These fees also compensate Nuveen for other expenses, including
printing and distributing prospectuses to persons other than shareholders, and
preparing, printing, and distributing advertising and sales literature and
reports to shareholders used in connection with the sale of shares. Because
these fees are paid out of the funds' assets on an on-going basis, over time
these fees will increase the cost of your investment and may cost you more than
paying other types of sales charges.

Nuveen periodically undertakes sales promotion programs with authorized dealers
and may pay them the full applicable sales charge as a commission. In addition,
Nuveen may provide support at its own expense to authorized dealers in
connection with sales meetings, seminars, prospecting seminars and other events
at which Nuveen presents its products and services. Under certain circumstances,
Nuveen also will share with authorized dealers up to half the costs of
advertising that features the products and services of both parties. The
Statement of Additional Information contains further information about these
programs.


Net Asset Value

The price you pay for your shares is based on the fund's net asset value per
share which is determined as of the close of trading (normally 4:00 p.m. New
York time) on each day the New York Stock Exchange is open for business. Net
asset value is calculated for each class by taking the market value of the
class' total assets, including interest or dividends accrued but not yet
collected, less all liabilities, and dividing by the total number of shares
outstanding. The result, rounded to the nearest cent, is the net asset value per
share. All valuations are subject to review by the funds' Board of Trustees or
its delegate.

In determining net asset value, expenses are accrued and applied daily and
securities and other assets for which market quotations are available are
valued at market value. The prices of municipal bonds are provided by a pricing
service and based on the mean between the bid and asked price. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on prices of comparable
municipal bonds.


Fund Service Providers

The custodian of the assets of the funds is The Chase Manhattan Bank, 4 New York
Plaza, New York, NY 10004-2413. Chase also provides certain accounting services
to the funds. The funds' transfer, shareholder services and dividend paying
agent, Chase Global Funds Services Company, P.O. Box 5186, New York, NY 10274-
5186, performs bookkeeping, data processing and administrative services for the
maintenance of shareholder accounts.

Section 5  Financial Highlights


The financial highlights table is intended to help you understand a fund's
financial performance for the past 5 years. Certain information reflects
financial results for a single fund share. The total returns in the table
represent the rate that an investor would have earned on an investment in a fund
(assuming reinvestment of all dividends and distributions). This information has
been audited by Arthur Andersen LLP, whose report, along with the funds'
financial statements, are included in the SAI and annual report, which is
available upon request.

INVESTMENT POLICIES AND INVESTMENT PORTFOLIO

Investment Policies

  The investment objectives and certain fundamental investment policies of each
Fund are described in the Prospectus. Each of the Funds, as a fundamental
policy, may not, without the approval of the holders of a majority of the
shares of that Fund:

    (1) Invest in securities other than Municipal Obligations and short-term
  securities, as described in the Prospectus. Municipal Obligations are
  municipal bonds that pay interest that is exempt from regular federal
  income taxes.

    (2) Invest more than 5% of its total assets in securities of any one
  issuer, except this limitation shall not apply to securities of the United
  States Government or to the investment of 25% of such Fund's assets (this
  subparagraph (2) does not apply to the High Yield Fund).

    (3) Borrow money, except from banks for temporary or emergency purposes
  and not for investment purposes and then only in an amount not exceeding
  (a) 10% of the value of its total assets at the time of borrowing or (b)
  one-third of the value of the Fund's total assets including the amount
  borrowed, in order to meet redemption requests which might otherwise
  require the untimely disposition of securities. While any such borrowings
  exceed 5% of such Fund's total assets, no additional purchases of
  investment securities will be made by such Fund. If due to market
  fluctuations or other reasons, the value of the Fund's assets falls below
  300% of its borrowings, the Fund will reduce its borrowings within 3
  business days. To do this, the Fund may have to sell a portion of its
  investments at a time when it may be disadvantageous to do so.

    (4) Pledge, mortgage or hypothecate its assets, except that, to secure
  borrowings permitted by subparagraph (2) above, it may pledge securities
  having a market value at the time of pledge not exceeding 10% of the value
  of the Fund's total assets.

    (5) Issue senior securities as defined in the Investment Company Act of
  1940, except to the extent such issuance might be involved with respect to
  borrowings described under item (3) above or with respect to transactions
  involving futures contracts or the writing of options within the limits
  described in the Prospectus and this Statement of Additional Information.

    (6) Underwrite any issue of securities, except to the extent that the
  purchase or sale of Municipal Obligations in accordance with its investment
  objective, policies and limitations, may be deemed to be an underwriting.

    (7) Purchase or sell real estate, but this shall not prevent any Fund
  from investing in Municipal Obligations secured by real estate or interests
  therein or foreclosing upon and selling such security.

    (8) Purchase or sell commodities or commodities contracts or oil, gas or
  other mineral exploration or development programs, except for transactions
  involving futures contracts within the limits described in the Prospectus
  and this Statement of Additional Information.

    (9) Make loans, other than by entering into repurchase agreements and
  through the purchase of Municipal Obligations or temporary investments in
  accordance with its investment objective, policies and limitations.

    (10) Make short sales of securities or purchase any securities on margin,
  except for such short-term credits as are necessary for the clearance of
  transactions.

                                      S-2
<PAGE>

    (11) Write or purchase put or call options, except to the extent that the
  purchase of a stand-by commitment may be considered the purchase of a put,
  and except for transactions involving options within the limits described
  in the Prospectus and this Statement of Additional Information.

    (12) Invest more than 25% of its total assets in securities of issuers in
  any one industry; provided, however, that such limitations shall not be
  applicable to Municipal Obligations issued by governments or political
  subdivisions of governments, and obligations issued or guaranteed by the
  U.S. Government, its agencies or instrumentalities.

    (13) Purchase or retain the securities of any issuer other than the
  securities of the Fund if, to the Fund's knowledge, those trustees of the
  Trust, or those officers and directors of Nuveen Advisory Corp. ("Nuveen
  Advisory"), who individually own beneficially more than 1/2 of 1% of the
  outstanding securities of such issuer, together own beneficially more than
  5% of such outstanding securities (this subparagraph (13) does not apply to
  the High Yield Fund).

  In addition, each Fund, as a non-fundamental policy, may not invest more than
15% of its net assets in "illiquid" securities, including repurchase agreements
maturing in more than seven days.

  For the purpose of applying the limitations set forth in paragraph (2) above,
an issuer shall be deemed the sole issuer of a security when its assets and
revenues are separate from other governmental entities and its securities are
backed only by its assets and revenues. Similarly, in the case of a non-
governmental user, such as an industrial corporation or a privately owned or
operated hospital, if the security is backed only by the assets and revenues of
the non-governmental user, then such non-governmental user would be deemed to
be the sole issuer. Where a security is also backed by the enforceable
obligation of a superior or unrelated governmental entity or other entity
(other than a bond insurer), it shall also be included in the computation of
securities owned that are issued by such governmental or other entity.

  Where a security is guaranteed by a governmental entity or some other
facility, such as a bank guarantee or letter of credit, such a guarantee or
letter of credit would be considered a separate security and would be treated
as an issue of such government, other entity or bank. Where a security is
insured by bond insurance, it shall not be considered a security issued or
guaranteed by the insurer; instead the issuer of such security will be
determined in accordance with the principles set forth above. The foregoing
restrictions do not limit the percentage of the Fund's assets that may be
invested in securities insured by any single insurer.

  The foregoing restrictions and limitations, as well as a Fund's policies as
to ratings of portfolio investments, will apply only at the time of purchase of
securities, and the percentage limitations will not be considered violated
unless an excess or deficiency occurs or exists immediately after and as a
result of an acquisition of securities, unless otherwise indicated.

  The foregoing fundamental investment policies, together with the investment
objective of each Fund, cannot be changed without approval by holders of a
"majority of the Fund's outstanding voting shares." As defined in the
Investment Company Act of 1940, this means the vote of (i) 67% or more of the
Fund's shares present at a meeting, if the holders of more than 50% of the
Fund's shares are present or represented by proxy, or (ii) more than 50% of the
Fund's shares, whichever is less.

  The Nuveen Municipal Trust, formerly Nuveen Flagship Municipal Trust (the
"Trust") is an open-end management series investment company organized as a
Massachusetts business trust on July 1, 1996. Each of the Funds is an open-end
management investment company organized as a series of the Trust. The Trust is
an open-end management series company under SEC Rule 18f-2. Each Fund is a
separate series issuing its own shares. The Trust currently has six series: the
Nuveen Intermediate Duration Municipal Bond Fund, formerly Nuveen Municipal
Bond Fund (originally incorporated in Maryland on October 8, 1976, reorganized
as a

                                      S-3
<PAGE>


Massachusetts business trust on June 12, 1995, and name changed on or about
August 28, 2000), the Nuveen Insured Municipal Bond Fund (formerly a series of
the Nuveen Insured Tax-Free Bond Fund, Inc., a Minnesota corporation
incorporated on July 14, 1986); the Nuveen All-American Municipal Bond Fund,
formerly Nuveen Flagship All-American Municipal Bond Fund (formerly the
Flagship All-American Tax Exempt Fund, a series of the Flagship Tax Exempt
Funds Trust); the Nuveen Intermediate Municipal Bond Fund, formerly Nuveen
Flagship Intermediate Municipal Bond Fund (formerly the Flagship Intermediate
Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the Nuveen
Limited Term Municipal Bond Fund, formerly Nuveen Flagship Limited Term
Municipal Bond Fund (formerly the Flagship Limited Term Tax Exempt Fund, a
series of the Flagship Tax Exempt Funds Trust); and the Nuveen High Yield
Municipal Bond Fund. All of the Funds except the High Yield Fund are
diversified for purposes of the Investment Company Act of 1940.

  The Board of Trustees of the Trust is authorized to issue an unlimited number
of shares in one or more series or "Funds," which may be divided into classes
of shares. The six series authorized and outstanding are divided into four
classes of shares designated Class A Shares, Class B Shares, Class C Shares and
Class R Shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund. Each class of shares has equal rights as
to voting, redemption, dividends and liquidation, except that each bears
different class expenses, including different distribution and service fees,
and each has exclusive voting rights with respect to any distribution or
service plan applicable to its shares. There are no conversion, preemptive or
other subscription rights, except that Class B Shares automatically convert
into Class A Shares, as described herein. The Board of Trustees of the Trust
has the right to establish additional series and classes of shares in the
future, to change those series or classes and to determine the preferences,
voting powers, rights and privileges thereof.

  The Trust is not required and does not intend to hold annual meetings of
shareholders. Shareholders owning more than 10% of the outstanding shares of
the Fund have the right to call a special meeting to remove Trustees or for any
other purpose.

  Certain matters under the Investment Company Act of 1940 which must be
submitted to a vote of the holders of the outstanding voting securities of a
series company shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding voting securities of
each Fund affected by such matter.

  The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of a trust may, under
certain circumstances, be held personally liable as partners for its
obligations. However, the Declaration of Trust contains an express disclaimer
of shareholder liability for acts or obligations of the Trust and requires that
notice of this disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Trust or the Trustees. The Declaration of Trust
further provides for indemnification out of the assets and property of the
Trust for all loss and expense of any shareholder personally liable for the
obligations of the Trust. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
both inadequate insurance existed and the Trust itself were unable to meet its
obligations. The Trust believes the likelihood of these circumstances is
remote.

Portfolio Securities

  As described in the Prospectus, each Fund invests primarily in a portfolio of
Municipal Obligations issued within the 50 states and certain U.S. possessions
and territories. In general, Municipal Obligations include debt obligations
issued by states, cities and local authorities to obtain funds for various
public purposes, including construction of a wide range of public facilities
such as airports, bridges, highways, hospitals, housing, mass transportation,
schools, streets and water and sewer works. Industrial development bonds and
pollution control

                                      S-4
<PAGE>

bonds that are issued by or on behalf of public authorities to finance various
privately-rated facilities are included within the term Municipal Obligations
if the interest paid thereon is exempt from federal income tax.

  The investment assets of the Intermediate Duration, Insured, All-American,
Intermediate, and Limited Term Funds will consist of (1) Municipal Obligations
which are rated at the time of purchase within the four highest grades (Baa or
BBB or better) by Moody's Investors Service, Inc. ("Moody's"), by Standard and
Poor's Corporation ("S&P") or by Fitch, Inc. ("Fitch"), (2) unrated Municipal
Obligations which, in the opinion of Nuveen Advisory, have credit
characteristics equivalent to bonds rated within the four highest grades by
Moody's, S&P or Fitch, and (3) temporary investments as described below, the
income from which may be subject to state income tax or to both federal and
state income taxes. The investment assets of the High Yield Fund will consist
of (1) Municipal Obligations rated BBB/Baa or lower (at least 65%), (2) unrated
Municipal Obligations Nuveen Advisory judges of equivalent quality, and (3)
temporary investments, the income from which may be subject to state income tax
or both state and federal income taxes. Under normal circumstances, the High
Yield Fund will invest at least 65% of its assets in medium- to low-quality
bonds rated BBB/Baa or lower by S&P, Moody's or Fitch or are unrated fixed-
income securities which, in the opinion of Nuveen Advisory, are of comparable
quality. As a temporary defensive measure, in response to unusual market
conditions, lack of acceptable supply or times when yield spreads do not
justify the increased risks of investing in these securities, the Fund may
invest in higher quality Municipal Obligations (those rated AAA/Aaa to A or, if
unrated, judged by Nuveen Advisory to be of comparable quality) or in short-
term, high-quality investments. The Fund may invest up to 10% of its net assets
in defaulted Municipal Obligations. "Defaulted" means that the municipal bond's
issuer has not paid principal or interest on time. See Appendix A for more
information about ratings by Moody's, S&P, and Fitch.

  As described in the Prospectus, each Fund may invest in Municipal Obligations
that constitute participations in a lease obligation or installment purchase
contract obligation (hereafter collectively called "lease obligations") of a
municipal authority or entity. Although lease obligations do not constitute
general obligations of the municipality for which the municipality's taxing
power is pledged, a lease obligation is ordinarily backed by the municipality's
covenant to budget for, appropriate and make the payments due under the lease
obligation. However, certain lease obligations contain "non-appropriation"
clauses which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. Although nonappropriation lease obligations are
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. A Fund will seek to minimize the special
risks associated with such securities by only investing in those
nonappropriation leases where Nuveen Advisory has determined that the issuer
has a strong incentive to continue making appropriations and timely payment
until the security's maturity. Some lease obligations may be illiquid under
certain circumstances. Lease obligations normally provide a premium interest
rate which along with regular amortization of the principal may make them
attractive for a portion of the assets of the Funds.

  Obligations of issuers of Municipal Obligations are subject to the provisions
of bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors. In addition, the obligations of such issuers may become subject to
the laws enacted in the future by Congress, state legislatures or referenda
extending the time for payment of principal and/or interest, or imposing other
constraints upon enforcement of such obligations or upon municipalities to levy
taxes. There is also the possibility that, as a result of legislation or other
conditions, the power or ability of any issuer to pay, when due, the principal
of and interest on its Municipal Obligations may be materially affected.

  High Yield Fund. Non-Investment Grade Debt Securities ("Junk Bonds"). Under
normal circumstances, at least 65% of the High Yield Fund's net assets will be
invested in medium- to low-quality Municipal Obligations.

                                      S-5
<PAGE>


Municipal Obligations rated below investment grade (BB/Ba or lower) are
commonly known as "high-yield," "high risk" or "junk" bonds. Junk bonds, while
generally offering higher yields than investment grade securities with similar
maturities, involve greater risks, including the possibility of default or
bankruptcy. They are regarded as predominantly speculative with respect to the
issuer's capacity to pay interest and repay principal. The special risk
considerations in connection with investments in these securities are discussed
below. Refer to Appendix A of this Statement of Additional Information for a
discussion of securities ratings.

    (1) Effect of Interest Rates and Economic Changes. The junk bond market
  is relatively new and its growth has paralleled a long economic expansion.
  As a result, it is not clear how this market may withstand a prolonged
  recession or economic downturn. Such an economic downturn could severely
  disrupt the market for and adversely affect the value of such securities.

    All interest-bearing securities typically experience appreciation when
  interest rates decline and depreciation when interest rates rise. In
  addition, the market values of junk bond securities tend to reflect
  individual corporate developments to a greater extent than do the market
  values of higher rated securities, which react primarily to fluctuations in
  the general level of interest rates. Junk bond securities also tend to be
  more sensitive to economic conditions than are higher rated securities. As
  a result, they generally involve more credit risk than securities in the
  higher rated categories. During an economic downturn or a sustained period
  of rising interest rates, highly leveraged issuers of junk bond securities
  may experience financial stress and may not have sufficient revenues to
  meet their payment obligations. The risk of loss due to default by an
  issuer of these securities is significantly greater than by an issuer of
  higher rated securities because such securities are generally unsecured and
  are often subordinated to other creditors. Further, if the issuer of a junk
  bond security defaults, the Fund may incur additional expenses to seek
  recovery. Periods of economic uncertainty and changes would also generally
  result in increased volatility in the market prices of these and thus in
  the Fund's net asset value.

    The value of a junk bond security will generally decrease in a rising
  interest rate market and, accordingly, so will the Fund's net asset value.
  If the Fund experiences unexpected net redemptions in such a market, it may
  be forced to liquidate a portion of its portfolio securities without regard
  to their investment merits. Due to the limited liquidity of junk bond
  securities, the Fund may be forced to liquidate these securities at a
  substantial discount. Any such liquidation would reduce the Fund's asset
  base over which expenses could be allocated and could result in a reduced
  rate of return for the Fund.

    (2) Payment Expectations. Junk bond securities typically contain
  redemption, call, or prepayment provisions that permit the issuer of
  securities containing such provisions to redeem the securities at its
  discretion. During periods of falling interest rates, issuers of these
  securities are likely to redeem or prepay the securities and refinance them
  with debt securities with a lower interest rate. To the extent an issuer is
  able to refinance the securities, or otherwise redeem them, the Fund may
  have to replace the securities with a lower yielding securities, which
  could result in a lower return for the Fund.

    (3) Credit Ratings. Credit ratings are issued by credit rating agencies
  and are indicative of the rated securities' safety of principal and
  interest payments. They do not, however, evaluate the market value risk of
  junk bond securities and, therefore, may not fully reflect the true risks
  of such an investment. In addition, credit rating agencies may not make
  timely changes in a rating to reflect changes in the economy or in the
  condition of the issuer that affect the value of the security.
  Consequently, credit ratings are used only as a preliminary indicator of
  investment quality. Investments in junk bonds will depend more upon credit
  analysis by Nuveen Advisory than investments in investment grade debt
  securities. Nuveen Advisory employs its own credit research and analysis,
  which includes a study of the issuer's existing debt, capital structure,
  ability to service debts and pay dividends, sensitivity to economic
  conditions, operating history, and current earnings trend. Nuveen Advisory
  continually monitors the Fund's investments and carefully

                                      S-6
<PAGE>


  evaluates whether to dispose of or to retain junk bond securities whose
  credit ratings or credit quality may have changed.

    (4) Liquidity and Valuation. The High Yield Fund may have difficulty
  disposing of certain junk bond securities because there may be a thin
  trading market for such securities. Not all dealers maintain markets in all
  junk bond securities. As a result, there is no established retail secondary
  market for many of these securities. The Fund anticipates that such
  securities could be sold only to a limited number of dealers or
  institutional investors. To the extent a secondary trading market does
  exist, it is generally not as liquid as the secondary market for higher
  rated securities. The lack of a liquid secondary market may have an adverse
  impact on the market price of the security. The lack of a liquid secondary
  market for certain securities may also make it more difficult for the Fund
  to obtain accurate market quotations for purposes of valuing its
  securities. Market quotations are generally available on many junk bond
  issues only from a limited number of dealers and may not necessarily
  represent firm bids of such dealers or prices for actual sales. During
  periods of thin trading, the spread between bid and asked prices is likely
  to increase significantly. In addition, adverse publicity and investor
  perceptions, whether or not based on fundamental analysis, may decrease the
  value and liquidity of junk bond securities, especially in a thinly traded
  market.

  The High Yield Fund may invest up to 10% of its net assets in defaulted
Municipal Obligations. Municipal Obligations in the lowest rating categories
may be in default and are generally regarded as having poor prospects of
attaining any real investment standing. A default or expected default in a
Municipal Obligation owned by the Fund could result in a significant decline in
the value of that Municipal Obligation.

Investments in Inverse Floating Rate Securities

  The Funds may invest in inverse floating rate municipal securities or
"inverse floaters", whose rates vary inversely to interest rates on a specified
index or on another instrument. Such securities involve special risks as
compared to conventional fixed-rate bonds. Should short-term interest rates
rise, a fund's investment in inverse floaters likely would adversely affect the
fund's earnings and distributions to shareholders. Also, because changes in the
interest rate on the other security or index inversely affect the rate of
interest received on an inverse floater, and because inverse floaters
essentially represent a leveraged investment in a long-term bond, the value of
an inverse floater is generally more volatile than that of a conventional
fixed-rate bond having similar credit quality, redemption provisions and
maturity. Although volatile in value, inverse floaters typically offer the
potential for yields substantially exceeding the yields available on fixed-rate
bonds with comparable credit quality, coupon, call provisions and maturity. The
markets for such securities may be less developed and have less liquidity than
the markets for conventional securities. Each Fund, as a non-fundamental policy
that may be changed by the Board of Trustees, will not invest more than 15% of
its total assets in inverse floaters.

Insurance

  Each insured Municipal Obligation held by the Nuveen Insured Municipal Bond
Fund will either be (1) covered by an insurance policy applicable to a specific
security and obtained by the issuer of the security or a third party at the
time of original issuance ("Original Issue Insurance"), (2) covered by an
insurance policy applicable to a specific security and obtained by the Fund or
a third party subsequent to the time of original issuance ("Secondary Market
Insurance"), or (3) covered by a master municipal insurance policy purchased by
the Fund ("Portfolio Insurance"). The Fund currently maintains a policy of
Portfolio Insurance with MBIA Insurance Corporation, Ambac Assurance
Corporation, Financial Security Assurance Inc., and Financial Guaranty
Insurance Company, and may in the future obtain other policies of Portfolio
Insurance, depending on the availability of such policies on terms favorable to
the Fund. However, the Fund may determine not to obtain such policies and to
emphasize investments in Municipal Obligations insured under Original Issue
Insurance or Secondary Market Insurance. In any event, the Fund will only
obtain policies of Portfolio Insurance issued by

                                      S-7
<PAGE>

insurers whose claims-paying ability is rated Aaa by Moody's Investors Service,
Inc. ("Moody's") or AAA by Standard & Poor's Corporation ("S&P"). The Fund
currently intends to obtain insurance polices only from mono-line insurers
specializing in insuring municipal debt. Municipal Obligations covered by
Original Issue Insurance or Secondary Market Insurance are themselves typically
assigned a rating of Aaa or AAA, as the case may be, by virtue of the Aaa or
AAA claims-paying ability of the insurer and would generally be assigned a
lower rating if the ratings were based primarily upon the credit
characteristics of the issuer without regard to the insurance feature. By way
or contrast, the ratings, if any, assigned to Municipal Obligations insured
under Portfolio Insurance will be based primarily upon the credit
characteristics of the issuers without regard to the insurance feature, and
will generally carry a rating that is below Aaa or AAA. While in the portfolio
of the Fund, however, a Municipal Obligation backed by Portfolio Insurance will
effectively be of the same quality as a Municipal Obligation issued by an
issuer of comparable credit characteristics that is backed by Original Issue
Insurance or Secondary Market Insurance.

  The Fund's policy of investing in Municipal Obligations insured by insurers
whose claims-paying ability is rated Aaa or AAA will apply only at the time of
the purchase of a security, and a Fund will not be required to dispose of
securities in the event Moody's or S&P, as the case may be, downgrades its
assessment of the claims-paying ability of a particular insurer or the credit
characteristics of a particular issuer. In this connection, it should be noted
that in the event Moody's or S&P or both should down-grade its assessment of
the claims-paying ability of a particular insurer, it could also be expected to
downgrade the ratings assigned to Municipal Obligations insured under Original
Issue Insurance or Secondary Market Insurance issued by such insurer, and
Municipal Obligations insured under Portfolio Insurance issued by such insurer
would also be of reduced quality in the portfolio of the Fund. Moody's and S&P
continually assess the claims-paying ability of insurers and the credit
characteristics of issuers, and there can be no assurance that they will not
downgrade their assessments subsequent to the time the Fund purchases
securities.

  In addition to insured Municipal Obligations, the Fund may invest in
Municipal Obligations that are entitled to the benefit of an escrow or trust
account which contains securities issued or guaranteed by the U.S. Government
or U.S. Government agencies, backed by the full faith and credit of the United
States, and sufficient in amount to ensure the payment of interest and
principal on the original interest payment and maturity dates ("collateralized
obligations"). These collateralized obligations generally will not be insured
and will include, but are not limited to, Municipal Obligations that have been
(1) advance refunded where the proceeds of the refunding have been used to
purchase U.S. Government or U.S. Government agency securities that are placed
in escrow and whose interest or maturing principal payments, or both, are
sufficient to cover the remaining scheduled debt service on the Municipal
Obligations, and (2) issued under state or local housing finance programs which
use the issuance proceeds to fund mortgages that are then exchanged for U.S.
Government or U.S. Government agency securities and deposited with a trustee as
security for the Municipal Obligations. These collateralized obligations are
normally regarded as having the credit characteristics of the underlying U.S.
Government or U.S. Government agency securities. Collateralized obligations
will not constitute more than 20% of the Fund's assets.

  Each insured Municipal Obligation in which the Fund invests will be covered
by Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
There is no limitation on the percentage of the Fund's assets that may be
invested in Municipal Obligations insured by any given insurer.

  Original Issue Insurance. Original Issue Insurance is purchased with respect
to a particular issue of Municipal Obligations by the issuer thereof or a third
party in conjunction with the original issuance of such Municipal Obligations.
Under such insurance, the insurer unconditionally guarantees to the holder of
the Municipal Obligation the timely payment of principal and interest on such
obligation when and as such payments shall become due but shall not be paid by
the issuer, except that in the event of any acceleration of the

                                      S-8
<PAGE>

due date of the principal by reason of mandatory or optional redemption (other
than acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the payments guaranteed may be made in such amounts and at such
times as payments of principal would have been due had there not been such
acceleration. The insurer is responsible for such payments less any amounts
received by the holder from any trustee for the Municipal Obligation issuers or
from any other source. Original Issue Insurance does not guarantee payment on
an accelerated basis, the payment of any redemption premium (except with
respect to certain premium payments in the case of certain small issue
industrial development and pollution control Municipal Obligations), the value
of the shares of the Fund, the market value of Municipal Obligations, or
payments of any tender purchase price upon the tender of the Municipal
Obligations. Original Issue Insurance also does not insure against nonpayment
of principal of or interest on Municipal Obligations resulting from the
insolvency, negligence or any other act or omission of the trustee or other
paying agent for such obligations.

  In the event that interest on or principal of a Municipal Obligation covered
by insurance is due for payment but is unpaid by the issuer thereof, the
applicable insurer will make payments to its fiscal agent (the "Fiscal Agent")
equal to such unpaid amounts of principal and interest not later than one
business day after the insurer has been notified that such nonpayment has
occurred (but not earlier than the date such payment is due). The Fiscal Agent
will disburse to the Fund the amount of principal and interest which is then
due for payment but is unpaid upon receipt by the Fiscal Agent of (i) evidence
of the Fund's right to receive payment of such principal and interest and (ii)
evidence, including any appropriate instruments of assignment, that all of the
rights to payment of such principal or interest then due for payment shall
thereupon vest in the insurer. Upon payment by the insurer of any principal or
interest payments with respect to any Municipal Obligations, the insurer shall
succeed to the rights of the Fund with respect to such payment.

  Original Issue Insurance remains in effect as long as the Municipal
Obligations covered thereby remain outstanding and the insurer remains in
business, regardless of whether the Fund ultimately disposes of such Municipal
Obligations. Consequently, Original Issue Insurance may be considered to
represent an element of market value with respect to the Municipal Obligations
so insured, but the exact effect, if any, of this insurance on such market
value cannot be estimated.

  Secondary Market Insurance. Subsequent to the time of original issuance of a
Municipal Obligation, the Fund or a third party may, upon the payment of a
single premium, purchase insurance on such Municipal Obligation. Secondary
Market Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and remains in effect as long as the Municipal
Obligation covered thereby remain outstanding, the holder of such Municipal
Obligation does not voluntarily relinquish the Secondary Market Insurance and
the insurer remains in business, regardless of whether the Fund ultimately
disposes of such Municipal Obligation.

  One of the purposes of acquiring Secondary Market Insurance with respect to a
particular Municipal Obligation would be to enable the Fund to enhance the
value of such Municipal Obligation. The Fund, for example, might seek to
purchase a particular Municipal Obligation and obtain Secondary Market
Insurance with respect thereto if, in the opinion of Nuveen Advisory, the
market value of such Municipal Obligation, as insured, would exceed the current
value of the Municipal Obligation without insurance plus the cost of the
Secondary Market Insurance. Similarly, if the Fund owns but wishes to sell a
Municipal Obligation that is then covered by Portfolio Insurance, the Fund
might seek to obtain Secondary Market Insurance with respect thereto if, in the
opinion of Nuveen Advisory, the net proceeds of a sale by the Fund of such
obligation, as insured, would exceed the current value of such obligation plus
the cost of the Secondary Market Insurance.

  Portfolio Insurance. Portfolio Insurance guarantees the payment of principal
and interest on specified eligible Municipal Obligations purchased by the Fund.
Except as described below, Portfolio Insurance generally provides the same type
of coverage as is provided by Original Issue Insurance or Secondary Market
Insurance. Municipal

                                      S-9
<PAGE>

Obligations insured under one Portfolio Insurance policy would generally not be
insured under any other policy purchased by the Fund. A Municipal Obligation is
eligible for coverage under a policy if it meets certain requirements of the
insurer. Portfolio Insurance is intended to reduce financial risk, but the cost
thereof and compliance with investment restrictions imposed under the policy
will reduce the yield to shareholders of the Fund.

  If a Municipal Obligation is already covered by Original Issue Insurance or
Secondary Market Insurance, then such Municipal Obligation is not required to
be additionally insured under any policy of Portfolio Insurance that the Fund
may purchase. All premiums respecting Municipal Obligations covered by Original
Issue Insurance or Secondary Market Insurance are paid in advance by the issuer
or other party obtaining the insurance.

  Portfolio Insurance policies are effective only as to Municipal Obligations
owned by and held by the Fund, and do not cover Municipal Obligations for which
the contract for purchase fails. A "when-issued" Municipal Obligation will be
covered under a Portfolio Insurance policy upon the settlement date of the
issue of such "when-issued" Municipal Obligation. In determining whether to
insure Municipal Obligations held by the Fund, an insurer will apply its own
standards, which correspond generally to the standards it has established for
determining the insurability of new issues of Municipal Obligations. See
"Original Issue Insurance" above.

  Each Portfolio Insurance policy will be noncancellable and will remain in
effect so long as the Fund is in existence, the Municipal Obligations covered
by the policy continue to be held by the Fund, and the Fund pays the premiums
for the policy. Each insurer will generally reserve the right at any time upon
90 days' written notice to the Fund to refuse to insure any additional
securities purchased by the Fund after the effective date of such notice. The
Board of Trustees will generally reserve the right to terminate each policy
upon seven days' written notice to an insurer if it determines that the cost of
such policy is not reasonable in relation to the value of the insurance to the
Fund.

  Each Portfolio Insurance policy will terminate as to any Municipal Obligation
that has been redeemed from or sold by the Fund on the date of such redemption
or the settlement date of such sale, and an insurer shall not have any
liability thereafter under a policy as to any such Municipal Obligation, except
that if the date of such redemption or the settlement date of such sale occurs
after a record date and before the related payment date with respect to any
such Municipal Obligation, the policy will terminate as to such Municipal
Obligation on the business day immediately following such payment date. Each
policy will terminate as to all Municipal Obligations covered thereby on the
date on which the last of the covered Municipal Obligations mature, are
redeemed or are sold by the Fund.

  One or more policies of Portfolio Insurance may provide the Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance") with respect to a
Municipal Obligation that is to be sold by the Fund. The Fund would exercise
the right to obtain Permanent Insurance upon payment of a single, predetermined
insurance premium payable from the proceeds of the sale of such Municipal
Obligation. It is expected that the Fund will exercise the right to obtain
Permanent Insurance for a Municipal Obligation only if, in the opinion of
Nuveen Advisory, upon such exercise the net proceeds from the sale by the Fund
of such obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance.

  The Permanent Insurance premium with respect to each such obligation is
determined based upon the insurability of each such obligation as of the date
of purchase by the Fund and will not be increased or decreased for any change
in the creditworthiness of such obligation unless such obligation is in default
as to payment or principal or interest, or both. In such event, the Permanent
Insurance premium shall be subject to an increase predetermined at the date of
purchase by the Fund.

  The Fund generally intends to retain any insured securities covered by
Portfolio Insurance that are in default or in significant risk of default and
to place a value on the insurance, which ordinarily will be the difference
between the market value of the defaulted security and the market value of
similar securities of minimum investment grade (i.e., rated BBB) that are not
in default. In certain circumstances, however, Nuveen Advisory may determine
that an alternative value for the insurance, such as the difference between the
market value of the defaulted security and either its par value or the market
value of securities of a similar nature that are not in default or in
significant risk of default, is more appropriate. To the extent that the Fund
holds such defaulted securities, it may be limited in its ability to manage its
investment portfolio and to purchase other Municipal Obligations. Except as
described above with respect to securities covered by Portfolio Insurance that
are in default or subject to significant risk of default, the Funds will not
place any value on the insurance in valuing the Municipal Obligations that it
holds.

  Because each Portfolio Insurance policy will terminate as to Municipal
Obligations sold by the Fund on the date of sale, in which event the insurer
will be liable only for those payments of principal and interest that are then
due and owing (unless Permanent Insurance is obtained by the Fund), the
provision for this insurance will not enhance the marketability of securities
held by the Fund, whether or not the securities are in default or in
significant risk of default. On the other hand, since Original Issue Insurance
and Secondary Market Insurance generally will remain in effect as long as
Municipal Obligations covered thereby are outstanding, such insurance may
enhance the marketability of such securities, even when such securities are in
default or in significant risk of default, but the exact effect, if any, on
marketability cannot be estimated. Accordingly, the Funds may determine to
retain or, alternatively, to sell Municipal Obligations covered by Original
Issue Insurance or Secondary Market Insurance that are in default or in
significant risk of default.

  Premiums for a Portfolio Insurance policy are paid monthly, and are adjusted
for purchases and sales of Municipal Obligations covered by the policy during
the month. The yield on the Fund is reduced to the extent of the insurance
premiums it pays. Depending upon the characteristics of the Municipal
Obligations held by the Fund, the annual premium rate for policies of Portfolio
Insurance is estimated to range from .15% to .30% of the value of the Municipal
Obligations covered under the policy. Because the majority of the Municipal
Obligations in the Fund were not covered by policies of Portfolio Insurance
during the year ended April 30, 1999, premium expenses as a percentage of the
value of Municipal Obligations held by the Fund for such period were .00%.

  Set forth below is information about the various municipal bond insurers with
whom the Nuveen Insured Municipal Bond Fund currently maintains policies of
Portfolio Insurance.

  Ambac Assurance Corporation ("Ambac Assurance")

  Ambac Assurance Corporation ("Ambac Assurance") is a Wisconsin-domiciled
stock insurance corporation regulated by the Office of the Commissioner of
Insurance of the State of Wisconsin and licensed to do business in 50 states,
the District of Columbia, the Territory of Guam and the Commonwealth of Puerto
Rico, with admitted assets of approximately $4,031,000,000 (unaudited) and
statutory capital of approximately $2,474,000,000 (unaudited) as of March 31,
2000. Statutory capital consists of Ambac Assurance's policyholders' surplus
and statutory contingency reserve. Standard & Poor's Ratings Services, a
division of The McGraw-Hill Companies, Moody's Investors Service and Fitch,
Inc. have assigned a triple-A financial strength rating to Ambac Assurance.

  Ambac Assurance has obtained a ruling from the Internal Revenue Service to
the effect that the insuring of an obligation by Ambac Assurance will not
affect the treatment for federal income tax purposes of interest on such
obligation and that insurance proceeds representing maturing interest paid by
Ambac Assurance under policy provisions substantially identical to those
contained in its municipal bond insurance policy shall be treated for federal
income tax purposes in the same manner as if such payments were made by the
issuer of the Bonds.

  The Insurer's policy unconditionally and irrevocably guarantees to the Nuveen
Insured Municipal Bond Fund the full and complete payment required to be made
by or on behalf of the issuer to the applicable paying agent or its successor
of an amount equal to (i) the principal of (either at the stated maturity or by
advancement of maturity pursuant to a mandatory sinking fund payment) and
interest on, the Municipal Obligations as such payments shall become due but
shall not be so paid (except that in the event of any acceleration of the due
date of such principal by reason of mandatory or optional redemption or
acceleration resulting from default or otherwise, other than any advancement of
maturity pursuant to a mandatory sinking fund payment, the payments guaranteed
by the Insurer's policy shall be made in such amounts and at such times as such
payments of principal would have been due had there not been any such
acceleration) and (ii) the reimbursement of any such payment which is
subsequently recovered from the Fund pursuant to a final judgment by a court of
competent jurisdiction that such payment constitutes an avoidable preference to
the Fund within the meaning of any applicable bankruptcy law (a "Preference").

  The Insurer's policy does not insure against loss of any prepayment premium
which may at any time be payable with respect to any Municipal Obligation. The
Insurer's policy does not, under any circumstance, insure against loss relating
to: (i) optional or mandatory redemptions (other than mandatory sinking fund
redemptions); (ii) any payments to be made on an accelerated basis; (iii)
payments of the purchase price of Municipal Obligations upon tender thereof; or
(iv) any Preference relating to (i) through (iii) above. The Insurer's policy
also does not insure against nonpayment of principal of or interest on the
Municipal Obligations resulting from the insolvency, negligence or any other
act or omission of any paying agent for the Municipal Obligations.

  With respect to small issue industrial development bonds and pollution
control revenue bonds covered by the policy, the Insurer guarantees the full
and complete payments required to be made by or on behalf of an issuer of such
bonds if there occurs pursuant to the terms of the bonds an event which results
in the loss of the tax-exempt status of interest on such bonds, including
principal, interest or premium payments payable thereon, if any, as and when
required to be made by or on behalf of the issuer pursuant to the terms of such
bonds.

  When the Insurer receives from the paying agent or the Fund, (1) telephonic
or telegraphic notice (subsequently confirmed in writing by registered or
certified mail), or (2) written notice by registered or certified mail, that a
required payment of any insured amount which is then due has not been made, the
Insurer on the due date of such payment or within one business day after
receipt of notice of such nonpayment, whichever is later, will make a deposit
of funds, in an account with State Street Bank and Trust Company, N.A., in New
York, New York, or its successor, sufficient for the payment of any such
insured amounts which are then due. Upon presentment and surrender of such
Municipal Obligations or presentment of such other proof of ownership of the
Municipal Obligations, together with any appropriate instruments of assignment
to evidence the assignment of the insured amounts due on the Municipal
Obligations as are paid by the Insurer, and appropriate instruments to effect
the appointment of the Insurer as agent for the Fund in any legal proceeding
related to payment of insured amounts on Municipal Obligations, such
instruments being in a form satisfactory to State Street Bank and Trust
Company, N.A., State Street Bank and Trust Company, N.A. shall disburse to the
Fund or the paying agent payment of the insured amounts due on such Municipal
Obligations, less any amount held by the paying agent for the payment of such
insured amounts and legally available therefor.

  Financial Guaranty Insurance Company ("Financial Guaranty")

  The Portfolio Insurance Policy is non-cancellable except for failure to pay
the premium. The premium rate for each purchase of a security covered by the
Portfolio Insurance Policy is fixed for the life of the Insured Bond. The
insurance premiums are payable monthly by the Fund and are adjusted for
purchases, sales and payments prior to maturity of Insured Bonds during the
month. In the event of a sale of any Insured Bond by the Fund or payment
thereof prior to maturity, the Portfolio Insurance policy terminates as to such
Insured Bond.

                                      S-13
<PAGE>

  Under the provisions of the Portfolio Insurance Policy, Financial Guaranty
unconditionally and irrevocably agrees to pay to State Street Bank and Trust
Company, or its successor, as its agent (the "Fiscal Agent"), that portion of
the principal of and interest on the Insured Bonds which shall become due for
payment but shall be unpaid by reason of nonpayment by the issuer of the
Insured Bonds. The term "due for payment" means, when referring to the
principal of an Insured Bond, its stated maturity date or the date on which it
shall have been called for mandatory sinking fund redemption and does not refer
to any earlier date on which payment is due by reason of call for redemption
(other than by mandatory sinking fund redemption), acceleration or other
advancement of maturity and means, when referring to interest on an Insured
Bond, the stated date for payment of interest. In addition, the Portfolio
Insurance Policy covers nonpayment by the issuer that results from any payment
of principal or interest made by such issuer on the Insured Bond to the Fund
which has been recovered from the Fund or its shareholders pursuant to the
United States Bankruptcy Code by a trustee in bankruptcy in accordance with a
final, nonappealable order of a court having competent jurisdiction.

  Financial Guaranty will make such payments to the Fiscal Agent on the date
such principal or interest becomes due for payment or on the business day next
following the day on which Financial Guaranty shall have received notice of
nonpayment, whichever is later. The Fiscal Agent will disburse the Trustee the
face amount of principal and interest which is then due for payment but is
unpaid by reason of nonpayment by the issuer, but only upon receipt by the
Fiscal Agent of (i) evidence of the Trustee's right to receive payment of the
principal or interest due for payment and (ii) evidence, including any
appropriate instruments of assignment, that all of the rights to payment of
such principal or interest due for payment thereupon shall vest in Financial
Guaranty. Upon such disbursement, Financial Guaranty shall become the owner of
the Insured Bond, appurtenant coupon or right to payment of principal or
interest on such Insured Bond and shall be fully subrogated to all of the
Trustee's rights thereunder, including the right to payment, thereof.

  In determining whether to insure municipal securities held in the Fund,
Financial Guaranty will apply its own standards which are not necessarily the
same as the criteria used in regard to the selection of securities by the Fund.

  Certain of the municipal securities insured under the Portfolio Insurance
Policy may also be insured under an insurance policy obtained by the issuer of
such municipal securities. The premium for any insurance policy or policies
obtained by an issuer or Insured Bonds has been paid in advance by such issuer
and any such policy or policies are non-cancellable and will continue in force
so long as the Insured Bonds so insured are outstanding. Financial Guaranty has
also agreed, if requested by the Funds on or before the fifth day preceding the
1st day of any month, to insure to maturity Insured Bonds sold by the Trustee
during the month immediately following such request of the Fund. The premium
for any such insurance to maturity provided by Financial Guaranty is paid by
the Fund and any such insurance is non-cancellable and will continue in force
so long as the Bonds so insured are outstanding.

  Financial Guaranty is a wholly-owned subsidiary of FGIC Corporation (the
"Corporation"), a Delaware holding company. The Corporation is a subsidiary of
General Electric Capital Corporation ("GE Capital"). Neither the Corporation
nor GE Capital is obligated to pay the debts of or the claims against Financial
Guaranty. Financial Guaranty is a monoline financial guaranty insurer domiciled
in the State of New York and subject to regulation by the State of New York
Insurance Department. As of March 31, 2000, the total capital and surplus of
Financial Guaranty was $1.281 billion. Financial Guaranty prepares financial
statements on the basis of both statutory accounting principles and generally
accepted accounting principles. Copies of such financial statements may be
obtained by writing to Financial Guaranty at 115 Broadway, New York, New York
10006, Attention: Communications Department (telephone number: (212) 312-3000)
or to the New York State Insurance Department at 25 Beaver Street, New York,
New York 10004-2319, Attention: Financial Condition Property/Casualty Bureau
(telephone number: (212) 480-5187).

  The policies of insurance obtained by the Fund from Financial Guaranty and
the negotiations in respect thereof represent the only relationship between
Financial Guaranty and the Fund. Otherwise neither Financial Guaranty nor its
parent, FGIC Corporation, or any affiliate thereof has any significant
relationship, direct or indirect, with the Funds or the Board of Trustees of
the Funds.

  The above municipal bond insurers have insurance claims-paying ability
ratings of AAA from S&P and Aaa from Moody's. Financial Guaranty also has an
insurance claims-paying ability rating of AAA from Fitch.

  An S&P insurance claims-paying ability rating is an assessment of an
operating insurance company's financial capacity to meet obligations under an
insurance policy in accordance with its terms. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by S&P.
Capacity to honor insurance contracts is adjudged by S&P to be extremely strong
and highly likely to remain so over a long period of time. A Moody's insurance
claims-paying ability rating is an opinion of the ability of an insurance
company to repay punctually senior policyholder obligations and claims. An
insurer with an insurance claims-paying ability rating of Aaa is adjudged by
Moody's to be of the best quality. In the opinion of Moody's, the policy
obligations of an insurance company with an insurance claims-paying ability
rating of Aaa carry the smallest degree of credit risk and, while the financial
strength of these companies is likely to change, such changes as can be
visualized are most unlikely to impair the company's fundamentally strong
position.

  An insurance claims-paying ability rating by S&P or Moody's does not
constitute an opinion on any specific contract in that such an opinion can only
be rendered upon the review of the specific insurance contract. Furthermore, an
insurance claims-paying ability rating does not take into account deductibles,
surrender or cancellation penalties or the timeliness of payment, nor does it
address the ability of a company to meet nonpolicy obligations (i.e., debt
contracts).

  The assignment of ratings by S&P or Moody's to debt issues that are fully or
partially supported by insurance policies, contracts or guarantees is a
separate process form the determination of claims-paying ability ratings. The
likelihood of a timely flow of funds from the insurer to the trustee for the
bondholders is a key element in the rating determination for such debt issues.

  S&P's and Moody's ratings are not recommendations to buy, sell or hold the
Municipal Obligations insured by policies issued by Ambac Assurance, Financial
Security, MBIA or Financial Guaranty and such ratings may be subject to
revision or withdrawal at any time by the rating agencies. Any downward
revision or withdrawal of either or both ratings may have an adverse effect on
the market price of the Municipal Obligations insured by policies issued by
Ambac Assurance, Financial Security, MBIA or Financial Guaranty.

  S&P's ratings of Ambac Assurance, Financial Security, MBIA and Financial
Guaranty should be evaluated independent of Moody's ratings. Any further
explanation as to the significance of the ratings may be obtained only from the
applicable rating agency. See Appendix A for more information about ratings by
Moody's, S&P, and Fitch.

Portfolio Trading and Turnover

  The Funds will make changes in their investment portfolio from time to time
in order to take advantage of opportunities in the municipal market and to
limit exposure to market risk. The Funds may also engage to a limited extent in
short-term trading consistent with their investment objective. Securities may
be sold in anticipation of market decline or purchased in anticipation of
market rise and later sold. In addition, a security may be sold and another of
comparable quality purchased at approximately the same time to take advantage
of what Nuveen Advisory believes to be a temporary disparity in the normal
yield relationship between the two securities. Each Fund may make changes in
its investment portfolio in order to limit its exposure to changing market
conditions. Changes in a Fund's investments are known as "portfolio turnover."
While it is impossible to

                                      S-15
<PAGE>

predict future portfolio turnover rates, the annual portfolio turnover rate for
each of the Funds is generally not expected to exceed 75%. However, each Fund
reserves the right to make changes in its investments whenever it deems such
action advisable and, therefore, a Fund's annual portfolio turnover rate may
exceed 75% in particular years depending upon market conditions.

  The portfolio turnover rates for the Funds, for the 1999 and 2000 fiscal
year-end of each Fund as indicated, were

When-Issued or Delayed-Delivery Securities

  Each Fund may purchase and sell Municipal Obligations on a when-issued or
delayed-delivery basis. When-issued and delayed-delivery transactions arise
when securities are purchased or sold with payment and delivery beyond the
regular settlement date. (When-issued transactions normally settle within 15-45
days.) On such transactions the payment obligation and the interest rate are
fixed at the time the buyer enters into the commitment. The commitment to
purchase securities on a when-issued or delayed-delivery basis may involve an
element of risk because the value of the securities is subject to market
fluctuation, no interest accrues to the purchaser prior to settlement of the
transaction, and at the time of delivery the market value may be less than
cost. At the time a Fund makes the commitment to purchase a Municipal
Obligation on a when-issued or delayed-delivery basis, it will record the
transaction and reflect the amount due and the value of the security in
determining its net asset value. Likewise, at the time a Fund makes the
commitment to sell a Municipal Obligation on a delayed-delivery basis, it will
record the transaction and include the proceeds to be received in determining
its net asset value; accordingly, any fluctuations in the value of the
Municipal Obligation sold pursuant to a delayed-delivery commitment are ignored
in calculating net asset value so long as the commitment remains in effect. The
Funds will maintain designated readily marketable assets at least equal in
value to commitments to purchase when-issued or delayed-delivery securities,
such assets to be segregated by the Custodian specifically for the settlement
of such commitments. The Funds will only make commitments to purchase Municipal
Obligations on a when-issued or delayed-delivery basis with the intention of
actually acquiring the securities, but the Funds reserve the right to sell
these securities before the settlement date if it is deemed advisable. If a
when-issued security is sold before delivery any gain or loss would not be tax-
exempt. The Funds commonly engage in when-issued transactions in order to
purchase or sell newly-issued Municipal Obligations, and may engage in delayed-
delivery transactions in order to manage its operations more effectively.

  Each Fund also may buy when-issued and delayed-delivery securities that
settle more than 60 days after purchase. These transactions are called
"forwards." Municipal "forwards" pay higher interest after settlement than
standard bonds, to compensate the buyer for bearing market risk but deferring
income during the settlement period, and often can be bought at attractive
prices and yields. If a Fund knows that a portfolio bond will, or is likely to,
be called or mature on a specific future date, the Fund may buy forwards
settling on or

                                      S-16
<PAGE>


about that date to replace the called or maturing bond and "lock in" a
currently attractive interest rate. The High Yield Fund also may invest up to
15% of its assets in forwards that do not serve to replace a specific portfolio
bond.

Hedging and Other Defensive Actions

  Each Fund may periodically engage in hedging transactions. Hedging is a term
used for various methods of seeking to preserve portfolio capital value by
offsetting price changes in one investment through making another investment
whose price should tend to move in the opposite direction. It may be desirable
and possible in various market environments to partially hedge the portfolio
against fluctuations in market value due to interest rate fluctuations by
investment in financial futures and index futures as well as related put and
call options on such instruments. Both parties entering into an index or
financial futures contract are required to post an initial deposit of 1% to 5%
of the total contract price. Typically, option holders enter into offsetting
closing transactions to enable settlement in cash rather than take delivery of
the position in the future of the underlying security. Each Fund will only sell
covered futures contracts, which means that the Fund segregates assets equal to
the amount of the obligations.

  These transactions present certain risks. In particular, the imperfect
correlation between price movements in the futures contract and price movements
in the securities being hedged creates the possibility that losses on the hedge
by a Fund may be greater than gains in the value of the securities in such
series' portfolio. In addition, futures and options markets may not be liquid
in all circumstances. As a result, in volatile markets, a Fund may not be able
to close out the transaction without incurring losses substantially greater
than the initial deposit. Finally, the potential daily deposit requirements in
futures contracts create an ongoing greater potential financial risk than do
options transactions, where the exposure is limited to the cost of the initial
premium. Losses due to hedging transactions will reduce yield. Net gains, if
any, from hedging and other portfolio transactions will be distributed as
taxable distributions to shareholders.

  No Fund will make any investment (whether an initial premium or deposit or a
subsequent deposit) other than as necessary to close a prior investment if,
immediately after such investment, the sum of the amount of its premiums and
deposits would exceed 5% of such series' net assets. Each series will invest in
these instruments only in markets believed by the investment adviser to be
active and sufficiently liquid. For further information regarding these
investment strategies and risks presented thereby, see Appendix B to this
Statement of Additional Information.

  Each Fund reserves the right for liquidity or defensive purposes (such as
thinness in the market for municipal securities or an expected substantial
decline in value of long-term obligations), to temporarily invest up to 20% of
its assets in obligations issued or guaranteed by the U.S. Government and its
agencies or instrumentalities, including up to 5% in adequately collateralized
repurchase agreements relating thereto. Interest on each instrument is taxable
for federal income tax purposes and would reduce the amount of tax-free
interest payable to shareholders.

Other Investment Policies and Techniques of the High Yield Fund

  Illiquid Securities

  The High Yield Fund may invest in illiquid securities (i.e., securities that
are not readily marketable). For purposes of this restriction, illiquid
securities include, but are not limited to, restricted securities (securities
the disposition of which is restricted under the federal securities laws),
securities that may only be resold pursuant to Rule 144A under the Securities
Act of 1933, as amended (the "Securities Act"), but that are deemed to be
illiquid; and repurchase agreements with maturities in excess of seven days.
However, the Fund will not acquire illiquid securities if, as a result, such
securities would comprise more than 15% of the value of the Fund's net

                                      S-17
<PAGE>


assets. The Board of Trustees or its delegate has the ultimate authority to
determine, to the extent permissible under the federal securities laws, which
securities are liquid or illiquid for purposes of this 15% limitation. The
Board of Trustees has delegated to Nuveen Advisory the day-to-day determination
of the illiquidity of any fixed-income security, although it has retained
oversight and ultimate responsibility for such determinations. Although no
definitive liquidity criteria are used, the Board of Trustees has directed
Nuveen Advisory to look to such factors as (i) the nature of the market for a
security (including the institutional private resale market; the frequency of
trades and quotes for the security; the number of dealers willing to purchase
or sell the security; and the amount of time normally needed to dispose of the
security, the method of soliciting offers and the mechanics of transfer), (ii)
the terms of certain securities or other instruments allowing for the
disposition to a third party or the issuer thereof (e.g., certain repurchase
obligations and demand instruments), and (iii) other permissible relevant
facts.

  Restricted securities may be sold only in privately negotiated transactions
or in a public offering with respect to which a registration statement is in
effect under the Securities Act. Where registration is required, the Fund may
be obligated to pay all or part of the registration expenses and a considerable
period may elapse between the time of the decision to sell and the time the
Fund may be permitted to sell a security under an effective registration
statement. If, during such a period, adverse market conditions were to develop,
the Fund might obtain a less favorable price than that which prevailed when it
decided to sell. Illiquid securities will be priced at fair value as determined
in good faith by the Board of Trustees or its delegate. If, through the
appreciation of illiquid securities or the depreciation of liquid securities,
the Fund should be in a position where more than 15% of the value of its net
assets are invested in illiquid securities, including restricted securities
which are not readily marketable, the Fund will take such steps as is deemed
advisable, if any, to protect liquidity.

  Structured Notes

  The High Yield Fund may invest in structured notes, including "total rate of
return swaps" with rates of return determined by reference to the total rate of
return on one or more loans references in such notes. The rate of return on a
structured note may be determined by applying a multiplier to the rate of total
return on the referenced loan or loans. Application of a multiplier is
comparable to the use of leverage which magnifies the potential for gain and
the risk of loss because a relatively small decline in the value of a
referenced note could result in a relatively large loss in the value of the
structured note.

  Mortgage-Backed Securities

  The High Yield Fund may invest in fixed-income obligations backed by a pool
of mortgages. Mortgage-backed securities are issued both by U.S. government
agencies, including the Government National Mortgage Association (GNMA) the
Federal National Mortgage Association (FNMA) and the Federal Home Loan Mortgage
Corporation (FHLMC) and by private entities. The payment of interest and
principal on securities issued by U.S. government agencies is guaranteed by the
full faith and credit of the U.S. government (in the case of GNMA securities)
or the issuer (in the case of FNMA and FHLMC securities). However, the
guarantees do not apply to the market prices and yields of these securities,
which vary with changes in interest rates. Mortgage-backed securities issued by
private entities are structured similarly to mortgage-backed securities issued
by GNMA, FNMA and FHLMC. These securities and the underlying mortgages are not
guaranteed by government agencies. However, these securities generally are
structured with one or more types of credit enhancement by a third party.
Mortgage-backed securities permit borrowers to prepay their underlying
mortgages. Prepayments by borrowers on underlying obligations can alter the
effective maturity of these instruments.

  Zero Coupon Bonds

  The High Yield Fund may invest in zero coupon bonds. A zero coupon bond is a
bond that does not pay interest for its entire life. The market prices of zero
coupon bonds are affected to a greater extent by changes in prevailing levels
of interest rates and thereby tend to be more volatile in price than securities
that pay interest periodically. In addition, because the Fund accrues income
with respect to these securities prior to the receipt of such interest, it may
have to dispose of portfolio securities under disadvantageous circumstances in
order to obtain cash needed to pay income dividends in amounts necessary to
avoid unfavorable tax consequences.

  Standby Commitments

  The High Yield Fund may obtain standby commitments when it purchases
Municipal Obligations. A standby commitment gives the holder the right to sell
the underlying security to the seller at an agreed-upon price on certain dates
or within a specified period. The Fund will acquire standby commitments solely
to facilitate portfolio liquidity and not with a view to exercising them at a
time when the exercise price may exceed the current value of the underlying
securities. If the exercise price of a standby commitment held by the Fund
should exceed the current value of the underlying securities, the Fund may
refrain from exercising the standby commitment in order to avoid causing the
issuer of the standby commitment to sustain a loss and thereby jeopardizing the
Fund's business relationship with the issuer. The Fund will enter into standby
commitments only with banks and securities dealers that, in the opinion of
Nuveen Advisory, present minimal credit risks. However, if a securities dealer
or bank is unable to meet its obligation to repurchase the security when the
Fund exercises a standby commitment, the Fund might be unable to recover all or
a portion of any loss sustained from having to sell the security elsewhere.
Standby commitments will be valued at zero in determining the Fund's net asset
value.

  Lending of Portfolio Securities

  The High Yield Fund may lend its portfolio securities, up to 33 1/3% of its
total assets, including collateral received, to broker-dealers or institutional
investors. Such loans will be secured continuously by collateral at least equal
to the value of the securities lent by "marking to market" daily. The Fund will
continue to receive the equivalent of the interest or dividends paid by the
issuer of the securities lent and will retain the right to call, upon notice,
the lent securities. The Fund may also receive interest on the investment of
the collateral or a fee from the borrower as compensation for the loan. As with
other extensions of credit, there are risks of delay in recovery or even loss
of rights in the collateral should the borrower of the securities fail

Temporary or Short-Term Investments

  The Prospectus discusses briefly the ability of the Funds to invest a portion
of their assets in federally tax-exempt or taxable temporary or short-term
investments. Temporary investments will not exceed 20% of a Fund's assets
except when made for defensive purposes. The Funds will invest only in taxable
temporary investments that are either U.S. Government securities or are rated
within the highest grade by Moody's, S&P, or Fitch and mature within one year
from the date of purchase or carry a variable or floating rate of interest. See
Appendix A for more information about ratings by Moody's, S&P, and Fitch.

  The Funds may invest in the following federally tax-exempt temporary
investments:

    Bond Anticipation Notes (BANs) are usually general obligations of state
  and local governmental issuers which are sold to obtain interim financing
  for projects that will eventually be funded through the sale of long-term
  debt obligations or bonds. The ability of an issuer to meet its obligations
  on its BANs is primarily dependent on the issuer's access to the long-term
  municipal bond market and the likelihood that the proceeds of such bond
  sales will be used to pay the principal and interest on the BANs.

                                      S-19
<PAGE>

    Tax Anticipation Notes (TANs) are issued by state and local governments
  to finance the current operations of such governments. Repayment is
  generally to be derived from specific future tax revenues. Tax anticipation
  notes are usually general obligations of the issuer. A weakness in an
  issuer's capacity to raise taxes due to, among other things, a decline in
  its tax base or a rise in delinquencies, could adversely affect the
  issuer's ability to meet its obligations on outstanding TANs.

    Revenue Anticipation Notes (RANs) are issued by governments or
  governmental bodies with the expectation that future revenues from a
  designated source will be used to repay the notes. In general, they also
  constitute general obligations of the issuer. A decline in the receipt of
  projected revenues, such as anticipated revenues from another level of
  government, could adversely affect an issuer's ability to meet its
  obligations on outstanding RANs. In addition, the possibility that the
  revenues would, when received, be used to meet other obligations could
  affect the ability of the issuer to pay the principal and interest on RANs.

    Construction Loan Notes are issued to provide construction financing for
  specific projects. Frequently, these notes are redeemed with funds obtained
  from the Federal Housing Administration.

    Bank Notes are notes issued by local government bodies and agencies as
  those described above to commercial banks as evidence of borrowings. The
  purposes for which the notes are issued are varied but they are frequently
  issued to meet short-term working capital or capital-project needs. These
  notes may have risks similar to the risks associated with TANs and RANs.

    Tax-Exempt Commercial Paper (Municipal Paper) represents very short-term
  unsecured, negotiable promissory notes, issued by states, municipalities
  and their agencies. Payment of principal and interest on issues of
  municipal paper may be made from various sources, to the extent the funds
  are available therefrom. Maturities of municipal paper generally will be
  shorter than the maturities of TANs, BANs or RANs. There is a limited
  secondary market for issues of municipal paper.

  Certain Municipal Obligations may carry variable or floating rates of
interest whereby the rate of interest is not fixed, but varies with changes in
specified market rates or indices, such as a bank prime rate or a tax-exempt
money market index.

  While these various types of notes as a group represent the major portion of
the tax-exempt note market, other types of notes are occasionally available in
the marketplace and the Fund may invest in such other types of notes to the
extent permitted under its investment objective, policies and limitations. Such
notes may be issued for different purposes and may be secured differently from
those mentioned above.

  The Funds may also invest in the following taxable temporary investments:

    U.S. Government Direct Obligations are issued by the United States
  Treasury and include bills, notes and bonds.

    --Treasury bills are issued with maturities of up to one year. They are
     issued in bearer form, are sold on a discount basis and are payable at
     par value at maturity.

    --Treasury notes are longer-term interest bearing obligations with
     original maturities of one to seven years.

    --Treasury bonds are longer-term interest-bearing obligations with
     original maturities from five to thirty years.

  U.S. Government Agencies Securities--Certain federal agencies have been
established as instrumentalities of the United States Government to supervise
and finance certain types of activities. These agencies include, but are

                                      S-20
<PAGE>

not limited to, the Bank for Cooperatives, Federal Land Banks, Federal
Intermediate Credit Banks, Federal Home Loan Banks, Federal National Mortgage
Association, Government National Mortgage Association, Export-Import Bank of
the United States, and Tennessee Valley Authority. Issues of these agencies,
while not direct obligations of the United States Government, are either backed
by the full faith and credit of the United States or are guaranteed by the
Treasury or supported by the issuing agencies' right to borrow from the
Treasury. There can be no assurance that the United States Government itself
will pay interest and principal on securities as to which it is not legally so
obligated.

  Certificates of Deposit (CDs)--A certificate of deposit is a negotiable
interest bearing instrument with a specific maturity. CDs are issued by banks
in exchange for the deposit of funds and normally can be traded in the
secondary market, prior to maturity. The Fund will only invest in U.S. dollar
denominated CDs issued by U.S. banks with assets of $1 billion or more.

  Commercial Paper--Commercial paper is the term used to designate unsecured
short-term promissory notes issued by corporations. Maturities on these issues
vary from a few days to nine months. Commercial paper may be purchased from
U.S. corporations.

  Other Corporate Obligations--The Funds may purchase notes, bonds and
debentures issued by corporations if at the time of purchase there is less than
one year remaining until maturity or if they carry a variable or floating rate
of interest.

  Repurchase Agreements--A repurchase agreement is a contractual agreement
whereby the seller of securities (U.S. Government or Municipal Obligations)
agrees to repurchase the same security at a specified price on a future date
agreed upon by the parties. The agreed upon repurchase price determines the
yield during a Fund's holding period. Repurchase agreements are considered to
be loans collateralized by the underlying security that is the subject of the
repurchase contract. The Funds will only enter into repurchase agreements with
dealers, domestic banks or recognized financial institutions that in the
opinion of Nuveen Advisory present minimal credit risk. The risk to the Funds
is limited to the ability of the issuer to pay the agreed-upon repurchase price
on the delivery date; however, although the value of the underlying collateral
at the time the transaction is entered into always equals or exceeds the
agreed-upon repurchase price, if the value of the collateral declines there is
a risk of loss of both principal and interest. In the event of default, the
collateral may be sold but a Fund might incur a loss if the value of the
collateral declines, and might incur disposition costs or experience delays in
connection with liquidating the collateral. In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security,
realization upon the collateral by a Fund may be delayed or limited. Nuveen
Advisory will monitor the value of collateral at the time the transaction is
entered into and at all times subsequent during the term of the repurchase
agreement in an effort to determine that the value always equals or exceeds the
agreed upon price. In the event the value of the collateral declined below the
repurchase price, Nuveen Advisory will demand additional collateral from the
issuer to increase the value of the collateral to at least that of the
repurchase price. Each of the Funds will not invest more than 10% of its assets
in repurchase agreements maturing in more than seven days.

(1) The compensation paid (but not including amounts deferred) to the
    independent trustees for the fiscal year ended April 30, 2000 for services
    to the Trust.

(2) Pursuant to a deferred compensation agreement with the Trust, deferred
    amounts are treated as though an equivalent dollar amount has been invested
    in shares of one or more eligible Nuveen Funds. The amounts provided are
    the total deferred fees (including the return from the assumed investment
    in the eligible Nuveen Funds) payable from the Trust.

(3) Based on the compensation paid (including any amounts deferred) to the
    independent trustees for the fiscal year ended April 30, 2000 for services
    to the open-end and closed-end funds advised by NAC.

  Each trustee who is not affiliated with NAC receives a $60,000 annual
retainer for serving as a director or trustee of all funds for which NAC serves
as investment adviser or manager and a $1,000 fee per day plus expenses for
attendance at all meetings held on a day on which a regularly scheduled Board
meeting is held, a $1,000 fee per day plus expenses for attendance in person or
a $500 fee per day plus expenses for attendance by telephone at a meeting held
on a day which no regular Board meeting is held and a $250 fee per day plus
expenses for attendance in person or by telephone at a meeting of the Executive
Committee held solely to declare dividends. The annual retainer, fees and
expenses are allocated among the funds for which NAC serves as investment
adviser or manager on the basis of relative net asset sizes. The Trust requires
no employees other than its officers, all of whom are compensated by NAC or
Nuveen.

  The John Nuveen Company (JNC) maintains charitable contributions programs to
encourage the active support and involvement of individuals in the civic
activities of their community. These programs include a matching contributions
program and a direct contributions program. The independent trustees of the
funds managed by NAC are eligible to participate in the charitable
contributions program of JNC. Under the matching program, JNC will match the
personal contributions of a trustee to Section 501(c)(3) organizations up to an
aggregate maximum amount of $10,000 during any calendar year. Under its direct
(non-matching) program, JNC makes contributions to qualifying Section 501(c)(3)
organizations, as approved by the Corporate

                                      S-25

Contributions Committee of JNC. The independent trustees are also eligible to
submit proposals to the committee requesting that contributions be made under
this program to Section 501(c)(3) organizations, identified by the trustee, in
an aggregate amount not to exceed $5,000 during any calendar year. Any
contribution made by JNC under the direct program is made solely at the
discretion of the Corporate Contributions Committee.

  The officers and trustees of each Fund, in the aggregate, own less than 1% of
the shares of the Fund.

  The following table sets forth the percentage ownership of each person, who,
as of August 1, 2000, owns of record, or is known by Registrant to own of
record or beneficially 5% or more of any class of a Fund's shares.

  *Fund commenced operations on June 7, 1999.

  In addition to the management fee of Nuveen Advisory, each Fund pays all
other costs and expenses of its operations and a portion of the Trust's general
administrative expenses allocated in proportion to the net assets of each Fund.

  Nuveen Advisory is a wholly owned subsidiary of Nuveen Investments
("Nuveen"), the Funds' principal underwriter. Nuveen is sponsor of the Nuveen
Defined Portfolios, and is the principal underwriter for the Nuveen Mutual
Funds, and has served as co-managing underwriter for the shares of the Nuveen
Exchange-Traded Funds. Over 1,300,000 individuals have invested to date in
Nuveen's funds and Defined Portfolios. Founded in 1898, Nuveen is a subsidiary
of The John Nuveen Company which, in turn, is approximately 78% owned by The
St. Paul Companies, Inc. ("St. Paul"). St. Paul is located in St. Paul,
Minnesota and is principally engaged in providing property-liability insurance
through subsidiaries. Effective January 1, 1997, The John Nuveen Company
acquired Flagship Resources Inc., and as part of that acquisition, Flagship
Financial, the adviser to the Flagship Funds, was merged with Nuveen Advisory.

  The Funds, the other Nuveen funds, Nuveen Advisory, and other related
entities have adopted a code of ethics which essentially prohibits all Nuveen
fund management personnel, including Nuveen fund portfolio managers, from
engaging in personal investments which compete or interfere with, or attempt to
take advantage of, a Fund's anticipated or actual portfolio transactions, and
is designed to assure that the interests of Fund shareholders are placed before
the interests of Nuveen personnel in connection with personal investment
transactions.

PORTFOLIO TRANSACTIONS

  Nuveen Advisory is responsible for decisions to buy and sell securities for
the Funds and for the placement of the Funds' securities business, the
negotiation of the prices to be paid for principal trades and the allocation of
its transactions among various dealer firms. Portfolio securities will normally
be purchased directly from an underwriter or in the over-the-counter market
from the principal dealers in such securities, unless it appears that a better
price or execution may be obtained elsewhere. Portfolio securities will not be
purchased from Nuveen or its affiliates except in compliance with the
Investment Company Act of 1940.


                                      S-31
<PAGE>

  The Funds expect that substantially all portfolio transactions will be
effected on a principal (as opposed to an agency) basis and, accordingly, do
not expect to pay any brokerage commissions. Purchases from underwriters will
include a commission or concession paid by the issuer to the underwriter, and
purchases from dealers will include the spread between the bid and asked price.
Given the best price and execution obtainable, it will be the practice of the
Funds to select dealers which, in addition, furnish research information
(primarily credit analyses of issuers and general economic reports) and
statistical and other services to Nuveen Advisory. It is not possible to place
a dollar value on information and statistical and other services received from
dealers. Since it is only supplementary to Nuveen Advisory's own research
efforts, the receipt of research information is not expected to reduce
significantly Nuveen Advisory's expenses. While Nuveen Advisory will be
primarily responsible for the placement of the business of the Funds, the
policies and practices of Nuveen Advisory in this regard must be consistent
with the foregoing and will, at all times, be subject to review by the Board of
Trustees.

  Nuveen Advisory reserves the right to, and does, manage other investment
accounts and investment companies for other clients, which may have investment
objectives similar to the Funds. Subject to applicable laws and regulations,
Nuveen Advisory will attempt to allocate equitably portfolio transactions among
the Funds and the portfolios of its other clients purchasing or selling
securities whenever decisions are made to purchase or sell securities by a Fund
and one or more of such other clients simultaneously. In making such
allocations the main factors to be considered will be the respective investment
objectives of the Fund and such other clients, the relative size of portfolio
holdings of the same or comparable securities, the availability of cash for
investment by the Fund and such other clients, the size of investment
commitments generally held by the Fund and such other clients and opinions of
the persons responsible for recommending investments to the Fund and such other
clients. While this procedure could have a detrimental effect on the price or
amount of the securities available to the Funds from time to time, it is the
opinion of the Board of Trustees that the benefits available from Nuveen
Advisory's organization will outweigh any disadvantage that may arise from
exposure to simultaneous transactions.

  Under the Investment Company Act of 1940, the Funds may not purchase
portfolio securities from any underwriting syndicate of which Nuveen is a
member except under certain limited conditions set forth in Rule 10f-3. The
Rule sets forth requirements relating to, among other things, the terms of an
issue of Municipal Obligations purchased by a Fund, the amount of Municipal
Obligations which may be purchased in any one issue and the assets of a Fund
which may be invested in a particular issue. In addition, purchases of
securities made pursuant to the terms of the Rule must be approved at least
quarterly by the Board of Trustees, including a majority of the trustees who
are not interested persons of the Trust.

NET ASSET VALUE

  As stated in the Prospectus, the net asset value of the shares of the Funds
will be determined separately for each class of the Funds' shares by The Chase
Manhattan Bank, the Funds' custodian, as of the close of trading (normally 4:00
p.m. Eastern Time) on each day on which the New York Stock Exchange (the
"Exchange") is normally open for trading. The Exchange is not open for trading
on New Year's Day, Washington's Birthday, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The net asset
value per share of a class of shares of a Fund will be computed by dividing the
value of the Fund's assets attributable to the class, less the liabilities
attributable to the class, by the number of shares of the class outstanding.

  In determining net asset value for the Funds, the Funds' custodian utilizes
the valuations of portfolio securities furnished by a pricing service approved
by the trustees. Securities for which quotations are not readily available
(which constitute a majority of the securities held by the Funds) are valued at
fair value as determined by the pricing service using methods which include
consideration of the following: yields or prices of municipal

                                      S-32
<PAGE>

bonds of comparable quality, type of issue, coupon, maturity and rating;
indications as to value from dealers; and general market conditions. The
pricing service may employ electronic data processing techniques and/or a
matrix system to determine valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Trust under the general
supervision of the Board of Trustees.

TAX MATTERS

Federal Income Tax Matters

  The following discussion of federal income tax matters is based upon the
advice of Morgan, Lewis & Bockius LLP, counsel to the Trust.

  Each Fund intends to qualify under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code") for tax treatment as a regulated investment
company. In order to qualify as a regulated investment company, a Fund must
satisfy certain requirements relating to the source of its income,
diversification of its assets, and distributions of its income to shareholders.
First, a Fund must derive at least 90% of its annual gross income (including
tax-exempt interest) from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock or
securities, foreign currencies or other income (including but not limited to
gains from options and futures) derived with respect to its business of
investing in such stock or securities (the "90% gross income test"). Second, a
Fund must diversify its holdings so that, at the close of each quarter of its
taxable year, (i) at least 50% of the value of its total assets is comprised of
cash, cash items, United States Government securities, securities of other
regulated investment companies and other securities limited in respect of any
one issuer to an amount not greater in value than 5% of the value of a Fund's
total assets and to not more than 10% of the outstanding voting securities of
such issuer, and (ii) not more than 25% of the value of the total assets is
invested in the securities of any one issuer (other than United States
Government securities and securities of other regulated investment companies)
or two or more issuers controlled by a Fund and engaged in the same, similar or
related trades or businesses.

  As a regulated investment company, a Fund will not be subject to federal
income tax in any taxable year for which it distributes at least 90% of the sum
of (i) its "investment company taxable income" (which includes dividends,
taxable interest, taxable original issue discount and market discount income,
income from securities lending, net short-term capital gain in excess of long-
term capital loss, and any other taxable income other than "net capital gain"
(as defined below) and is reduced by deductible expenses) and (ii) its net tax-
exempt interest (the excess of its gross tax-exempt interest income over
certain disallowed deductions). A Fund may retain for investment its net
capital gain (which consists of the excess of its net long-term capital gain
over its short-term capital loss). However, if a Fund retains any net capital
gain or any investment company taxable income, it will be subject to tax at
regular corporate rates on the amount retained. If a Fund retains any capital
gain, such Fund may designate the retained amount as undistributed capital
gains in a notice to its shareholders who, if subject to federal income tax on
long-term capital gains, (i) will be required to include in income for federal
income tax purposes, as long-term capital gain, their shares of such
undistributed amount, and (ii) will be entitled to credit their proportionate
shares of the tax paid by such Fund against their federal income tax
liabilities if any, and to claim refunds to the extent the credit exceeds such
liabilities. For federal income tax purposes, the tax basis of shares owned by
a shareholder of the Fund will be increased by an amount equal under current
law to the difference between the amount of the includible gain and the tax
deemed paid by the shareholder in respect of such shares. Each Fund intends to
distribute at least annually to its shareholders all or substantially all of
its net tax-exempt interest and any investment company taxable income and net
capital gain.

                                      S-33
<PAGE>

  Treasury regulations permit a regulated investment company, in determining
its investment company taxable income and net capital gain, i.e., the excess of
net long-term capital gain over net short-term capital loss for any taxable
year, to elect (unless it has made a taxable year election for excise tax
purposes as discussed below) to treat all or part of any net capital loss, any
net long-term capital loss or any net foreign currency loss incurred after
October 31 as if they had been incurred in the succeeding year.

  Each Fund also intends to satisfy conditions (including requirements as to
the proportion of its assets invested in Municipal Obligations) that will
enable it to designate distributions from the interest income generated by
investments in Municipal Obligations, which is exempt from regular federal
income tax when received by such Fund, as exempt-interest dividends.
Shareholders receiving exempt-interest dividends will not be subject to regular
federal income tax on the amount of such dividends. Insurance proceeds received
by a Fund under any insurance policies in respect of scheduled interest
payments on defaulted Municipal Obligations will be excludable from federal
gross income under Section 103(a) of the Code. In the case of non-appropriation
by a political subdivision, however, there can be no assurance that payments
made by the insurer representing interest on "non-appropriation" lease
obligations will be excludable from gross income for federal income tax
purposes.

  Distributions by a Fund of net interest received from certain taxable
temporary investments (such as certificates of deposit, commercial paper and
obligations of the U.S. Government, its agencies and instrumentalities) and net
short-term capital gains realized by a Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional shares.
If a Fund purchases a Municipal Obligation at a market discount, any gain
realized by the Fund upon sale or redemption of the Municipal Obligation will
be treated as taxable interest income to the extent such gain does not exceed
the market discount, and any gain realized in excess of the market discount
will be treated as capital gains. Any net long-term capital gains realized by a
Fund and distributed to shareholders in cash or additional shares, will be
taxable to shareholders as long-term capital gains regardless of the length of
time investors have owned shares of a Fund. Distributions by a Fund that do not
constitute ordinary income dividends, exempt-interest dividends, or capital
gain dividends will be treated as a return of capital to the extent of (and in
reduction of) the shareholder's tax basis in his or her shares. Any excess will
be treated as gain from the sale of his or her shares, as discussed below.

  If a Fund has both tax-exempt and taxable income, it will use the "average
annual" method for determining the designated percentage that is taxable income
and designate the use of such method within 60 days after the end of the Fund's
taxable year. Under this method, one designated percentage is applied uniformly
to all distributions made during the Fund's taxable year. The percentage of
income designated as tax-exempt for any particular distribution may be
substantially different from the percentage of the Fund's income that was tax-
exempt during the period covered by the distribution.

  If a Fund engages in hedging transactions involving financial futures and
options, these transactions will be subject to special tax rules, the effect of
which may be to accelerate income to a Fund, defer a Fund's losses, cause
adjustments in the holding periods of a Fund's securities, convert long-term
capital gains into short-term capital gains and convert short-term capital
losses into long-term capital losses. These rules could therefore affect the
amount, timing and character of distributions to shareholders.

  Because the taxable portion of a Fund's investment income consists primarily
of interest, none of its dividends, whether or not treated as exempt-interest
dividends, is expected to qualify under the Internal Revenue Code for the
dividends received deductions for corporations.

  Prior to purchasing shares in a Fund, the impact of dividends or
distributions which are expected to be or have been declared, but not paid,
should be carefully considered. Any dividend or distribution declared shortly
after a purchase of such shares prior to the record date will have the effect
of reducing the per share net asset value by the per share amount of the
dividend or distribution.

                                      S-34
<PAGE>

  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during the following
January, will be treated as having been distributed by a Fund (and received by
the shareholders) on December 31.

  The redemption or exchange of the shares of a Fund normally will result in
capital gain or loss to the shareholders. Generally, a shareholder's gain or
loss will be long-term gain or loss if the shares have been held for more than
one year. Present law taxes both long- and short-term capital gains of
corporations at the rates applicable to ordinary income. For non-corporate
taxpayers, however, net capital gains (i.e., the excess of net long-term
capital gain over net short-term capital loss) will be taxed at a maximum
marginal rate of 20%, while short-term capital gains and other ordinary income
will be taxed at a maximum marginal rate of 39.6%. Because of the limitations
on itemized deductions and the deduction for personal exemptions applicable to
higher income taxpayers, the effective tax rate may be higher in certain
circumstances.

  All or a portion of a sales charge paid in purchasing shares of a Fund cannot
be taken into account for purposes of determining gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to
the extent shares of a Fund or another fund are subsequently acquired without
payment of a sales charge pursuant to the reinvestment or exchange privilege.
Any disregarded portion of such charge will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. Moreover, losses
recognized by a shareholder on the redemption or exchange of shares of a Fund
held for six months or less are disallowed to the extent of any distribution of
exempt-interest dividends received with respect to such shares and, if not
disallowed, such losses are treated as long-term capital losses to the extent
of any distributions of long-term capital gains made with respect to such
shares. In addition, no loss will be allowed on the redemption or exchange of
shares of a Fund if the shareholder purchases other shares of such Fund
(whether through reinvestment of distributions or otherwise) or the shareholder
acquires or enters into a contract or option to acquire securities that are
substantially identical to shares of a Fund within a period of 61 days
beginning 30 days before and ending 30 days after such redemption or exchange.
If disallowed, the loss will be reflected in an adjustment to the basis of the
shares acquired.

  It may not be advantageous from a tax perspective for shareholders to redeem
or exchange shares after tax-exempt income has accrued but before the record
date for the exempt-interest dividend representing the distribution of such
income. Because such accrued tax-exempt income is included in the net asset
value per share (which equals the redemption or exchange value), such a
redemption could result in treatment of the portion of the sales or redemption
proceeds equal to the accrued tax-exempt interest as taxable gain (to the
extent the redemption or exchange price exceeds the shareholder's tax basis in
the shares disposed of) rather than tax-exempt interest.

  In order to avoid a 4% federal excise tax, a Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
realized capital gains over its realized capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year) and 100% of
any taxable ordinary income and the excess of realized capital gains over
realized capital losses for the prior year that was not distributed during such
year and on which such Fund paid no federal income tax. For purposes of the
excise tax, a regulated investment company may reduce its capital gain net
income (but not below its net capital gain) by the amount of any net ordinary
loss for the calendar year. The Funds intend to make timely distributions in
compliance with these requirements and consequently it is anticipated that they
generally will not be required to pay the excise tax.

  If in any year a Fund should fail to qualify under Subchapter M for tax
treatment as a regulated investment company, the Fund would incur a regular
corporate federal income tax upon its income for that year (other than interest
income from Municipal Obligations), and distributions to its shareholders would
be taxable to

                                      S-35
<PAGE>

shareholders as ordinary dividend income for federal income tax purposes to the
extent of the Fund's available earnings and profits.

  Because the Funds may invest in private activity bonds, the interest on which
is not federally tax-exempt to persons who are "substantial users" of the
facilities financed by such bonds or "related persons" of such "substantial
users," the Funds may not be an appropriate investment for shareholders who are
considered either a "substantial user" or a "related person" within the meaning
of the Code. For additional information, investors should consult their tax
advisers before investing in a Fund.

  Federal tax law imposes an alternative minimum tax with respect to both
corporations and individuals. Interest on certain Municipal Obligations, such
as bonds issued to make loans for housing purposes or to private entities (but
not for certain tax-exempt organizations such as universities and non-profit
hospitals), is included as an item of tax preference in determining the amount
of a taxpayer's alternative minimum taxable income. To the extent that a Fund
receives income from Municipal Obligations subject to the alternative minimum
tax, a portion of the dividends paid by it, although otherwise exempt from
federal income tax, will be taxable to shareholders to the extent that their
tax liability is determined under the alternative minimum tax regime. The Funds
will annually supply shareholders with a report indicating the percentage of
Fund income attributable to Municipal Obligations subject to the federal
alternative minimum tax.

  In addition, the alternative minimum taxable income for corporations is
increased by 75% of the difference between an alternative measure of income
("adjusted current earnings") and the amount otherwise determined to be the
alternative minimum taxable income. Interest on all Municipal Obligations, and
therefore all distributions by the Funds that would otherwise be tax-exempt, is
included in calculating a corporation's adjusted current earnings.

  Tax-exempt income, including exempt-interest dividends paid by a Fund, will
be added to the taxable income of individuals receiving social security or
railroad retirement benefits in determining whether a portion of that benefit
will be subject to federal income tax.

  The Code provides that interest on indebtedness incurred or continued to
purchase or carry shares of any Fund is not deductible. Under rules used by the
IRS for determining when borrowed funds are considered used for the purpose of
purchasing or carrying particular assets, the purchase of shares of a Fund may
be considered to have been made with borrowed funds even though such funds are
not directly traceable to the purchase of shares.

  The Funds are required in certain circumstances to withhold 31% of taxable
dividends and certain other payments paid to non-corporate holders of shares
who have not furnished to the Funds their correct taxpayer identification
number (in the case of individuals, their social security number) and certain
certifications, or who are otherwise subject to backup withholding.

  The foregoing is a general and abbreviated summary of the provisions of the
Code and Treasury Regulations presently in effect as they directly govern the
taxation of the Fund and its shareholders. For complete provisions, reference
should be made to the pertinent Code sections and Treasury Regulations. The
Code and Treasury Regulations are subject to change by legislative or
administrative action, and any such change may be retroactive with respect to
Fund transactions. Shareholders are advised to consult their own tax advisors
for more detailed information concerning the federal taxation of the Funds and
the income tax consequences to their shareholders.

PERFORMANCE INFORMATION

  The historical investment performance of the Funds may be shown in the form
of "yield," "taxable equivalent yield," "average annual total return,"
"cumulative total return" and "taxable equivalent total return" figures, each
of which will be calculated separately for each class of shares.

  In accordance with a standardized method prescribed by rules of the
Securities and Exchange Commission ("SEC"), yield is computed by dividing the
net investment income per share earned during the specified one month or 30-day
period by the maximum offering price per share on the last day of the period,
according to the following formula:

                            Yield=2[(a-b +1)/6/ -1]
                                        cd

  In the above formula, a = dividends and interest earned during the period; b
= expenses accrued for the period (net of reimbursements); c = the average
daily number of shares outstanding during the period that were entitled to
receive dividends; and d = the maximum offering price per share on the last day
of the period. In the case of Class A shares, the maximum offering price
includes the current maximum front-end sales charge of 4.2% (3.0% for the
Intermediate Municipal Bond Fund and 2.5% for the Limited Term Municipal Bond
Fund).

  In computing yield, the Funds follow certain standardized accounting
practices specified by SEC rules. These practices are not necessarily
consistent with those that the Funds use to prepare their annual and interim
financial statements in conformity with generally accepted accounting
principles. Thus, yield may not equal the income paid to shareholders or the
income reported in a Fund's financial statements.

  Taxable equivalent yield is computed by dividing that portion of the yield
which is tax-exempt by the remainder of (1 minus the stated federal income tax
rate, taking into account the deductibility of state taxes for federal income
tax purposes) and adding the product to that portion, if any, of the yield that
is not tax exempt.

  The taxable equivalent yields quoted below are based upon (1) the stated
federal income tax rate and (2) the yields for the 30-day period quoted in the

  The Funds may from time to time in their advertising and sales materials
report a quotation of their current distribution rate. The distribution rate
represents a measure of dividends distributed for a specified period.
Distribution rate is computed by taking the most recent monthly tax-free income
dividend per share, multiplying it by 12 to annualize it, and dividing by the
appropriate price per share (e.g., net asset value for purchases to be made
without a load such as reinvestments from Nuveen Defined Portfolios, or the
maximum public offering price). The distribution rate differs from yield and
total return and therefore is not intended to be a complete measure of
performance. Distribution rate may sometimes differ from yield because a Fund
may be paying out more than it is earning and because it may not include the
effect of amortization of bond premiums to the extent such premiums arise after
the bonds were purchased.

  The distribution rates as of the period quoted, based on the maximum public
offering price then in effect for the Funds, and assuming the imposition of the
maximum sales charge for Class A Shares of 4.2% for the Nuveen Intermediate
Duration Municipal Bond Fund, the Nuveen Insured Municipal Bond Fund, Nuveen
High Yield Municipal Bond Fund and the Nuveen All-American Municipal Bond Fund;
the maximum sales charge for Class A Shares of 3.0% for the Nuveen Intermediate
Municipal Bond Fund; and the maximum sales charge for Class A Shares of 2.5%
for the Nuveen Limited Term Municipal Bond Fund, were as follows:

  Average annual total return quotation is computed in accordance with a
standardized method prescribed by SEC rules. The average annual total return
for a specific period is found by taking a hypothetical, $1,000 investment
("initial investment") in Fund shares on the first day of the period, reducing
the amount to reflect the maximum sales charge, and computing the "redeemable
value" of that investment at the end of the period. The redeemable value is
then divided by the initial investment, and this quotient is taken to the Nth
root (N representing the number of years in the period) and 1 is subtracted
from the result, which is then expressed as a percentage. The calculation
assumes that all income and capital gains distributions have been reinvested in
Fund shares at net asset value on the reinvestment dates during the period.

  Total returns for the oldest class of each fund reflect actual performance
for all periods. For other classes, total returns reflect actual performance
for periods since class inception, and the oldest class's performance for
periods prior to inception, adjusted for the differences in sales charges and
fees between the classes.

   * Fund commenced operations on June 7, 1999.

  Calculation of cumulative total return is not subject to a prescribed
formula. Cumulative total return for a specific period is calculated by first
taking a hypothetical initial investment in Fund shares on the first day of the
period, deducting (in some cases) the maximum sales charge, and computing the
"redeemable value" of that investment at the end of the period. The cumulative
total return percentage is then determined by subtracting the initial
investment from the redeemable value and dividing the remainder by the initial
investment and expressing the result as a percentage. The calculation assumes
that all income and capital gains distributions by

the Fund have been reinvested at net asset value on the reinvestment dates
during the period. Cumulative total return may also be shown as the increased
dollar value of the hypothetical investment over the period. Cumulative total
return calculations that do not include the effect of the sales charge would be
reduced if such charge were included.

  Calculation of taxable equivalent total return is also not subject to a
prescribed formula. The taxable equivalent total return of a tax-exempt fund
represents the pre-tax total return a hypothetical taxable fixed-income
investment paying the same after-tax income as the tax-exempt fund (based on an
assumed income tax rate) and otherwise experiencing the same investment
performance as the tax-exempt fund would have provided. This figure can
facilitate the comparison of otherwise comparable taxable and tax-exempt funds.
Taxable equivalent total return for a specific period is calculated by first
taking a hypothetical initial investment in Fund shares on the first day of the
period, computing the total return for each calendar year in the period in the
manner described above, and increasing the total return for each such calendar
year by the amount of additional income that a taxable fund would need to have
generated to equal the income on an after-tax basis, at a specified income tax
rate (usually the highest marginal federal tax rate), calculated as described
above under the discussion of "taxable equivalent yield." The resulting amount
for the calendar year is then divided by the initial investment amount to
arrive at a "taxable equivalent total return factor" for the calendar year. The
taxable equivalent total return factors for all the calendar years are then
multiplied together and the result is then annualized by taking its Nth root (N
representing the number of years in the period) and subtracting 1, which
provides a taxable equivalent total return expressed as a percentage.

  Using the 39.6% maximum marginal federal tax rate for 2000, the annual
taxable equivalent total return for the Nuveen Intermediate Duration Municipal
Bond Fund's Class R Shares for the ten-year period ended April 30, 2000, was
10.42%.

  Class A Shares of the Funds are sold at net asset value plus a current
maximum sales charge of 4.20% of the offering price (3.0% for the Intermediate
Municipal Bond Fund and 2.5% for the Limited Term Municipal Bond Fund). This
current maximum sales charge will typically be used for purposes of calculating
performance figures. Yield, returns and net asset value of each class of shares
of the Funds will fluctuate. Factors affecting the performance of the Funds
include general market conditions, operating expenses and investment
management. Any additional fees charged by a securities representative or other
financial services firm would reduce returns described in this section. Shares
of the Funds are redeemable at net asset value, which may be more or less than
original cost.

  In reports or other communications to shareholders or in advertising and
sales literature, the Funds may also compare their performance with that of:
(1) the Consumer Price Index or various unmanaged bond indexes such as the
Lehman Brothers Municipal Bond Index and the Salomon Brothers High Grade
Corporate Bond Index and (2) other fixed income or municipal bond mutual funds
or mutual fund indexes as reported by Lipper Analytical Services, Inc.
("Lipper"), Morningstar, Inc. ("Morningstar"), Wiesenberger Investment
Companies Service ("Wiesenberger") and CDA Investment Technologies, Inc.
("CDA") or similar independent services which monitor the performance of mutual
funds, or other industry or financial publications such as Barron's, Changing
Times, Forbes and Money Magazine. Performance comparisons by these indexes,
services or publications may rank mutual funds over different periods of time
by means of aggregate, average, year-by-year, or other types of total return
and performance figures. Any given performance quotation or performance
comparison should not be considered as representative of the performance of the
Funds for any future period.

  Each Fund may from time to time in its advertising and sales materials
compare its current yield or total return with the yield or total return on
taxable investments such as corporate or U.S. Government bonds, bank
certificates of deposit (CDs) or money market funds. These taxable investments
have investment characteristics that differ from those of the Funds. U.S.
Government bonds, for example, are long-term investments backed by the full
faith and credit of the U.S. Government, and bank CDs are generally short-term,
FDIC-insured investments, which pay fixed principal and interest but are
subject to fluctuating rollover rates. Money market funds are short-term
investments with stable net asset values, fluctuating yields and special
features enhancing liquidity.

  There are differences and similarities between the investments which the
Funds may purchase and the investments measured by the indexes and reporting
services which are described herein. The Consumer Price Index is generally
considered to be a measure of inflation. The CDA Mutual Fund-Municipal Bond
Index is a weighted performance average of other mutual funds with a federally
tax-exempt income objective. The Salomon Brothers High Grade Corporate Bond
Index is an unmanaged index that generally represents the performance of high
grade long-term taxable bonds during various market conditions. The Lehman
Brothers Municipal Bond Index is an unmanaged index that generally represents
the performance of high grade intermediate and long-term municipal bonds during
various market conditions. Lipper calculates municipal bond fund averages based
on average maturity and credit quality. Morningstar rates mutual funds by
overall risk-adjusted performance, investment objectives, and assets. Lipper,
Morningstar, Wiesenberger and CDA are widely recognized mutual fund reporting
services whose performance calculations are based upon changes in net asset
value with all dividends reinvested and which do not include the effect of any
sales charges. The market prices and yields of taxable and tax-exempt bonds
will fluctuate. The Funds primarily invest in investment grade Municipal
Obligations in pursuing their objective of as high a level of current interest
income which is exempt from federal and state income tax as is consistent, in
the view of the Funds' management, with preservation of capital.

  The Funds may also compare their taxable equivalent total return performance
to the total return performance of taxable income funds such as treasury
securities funds, corporate bond funds (either investment grade or high yield),
or Ginnie Mae funds. These types of funds, because of the character of their
underlying securities, differ from municipal bond funds in several respects.
The susceptibility of the price of treasury bonds to credit risk is far less
than that of municipal bonds, but the price of treasury bonds tends to be
slightly more susceptible to change resulting from changes in market interest
rates. The susceptibility of the price of investment grade corporate bonds and
municipal bonds to market interest rate changes and general credit changes is
similar. High yield bonds are subject to a greater degree of price volatility
than municipal bonds resulting from changes in market interest rates and are
particularly susceptible to volatility from credit changes. Ginnie Mae bonds
are generally subject to less price volatility than municipal bonds from credit
concerns, due primarily to the fact that the timely payment of monthly
installments of principal and interest are backed by the full faith and credit
of the U.S. Government, but Ginnie Mae bonds of equivalent coupon and maturity
are generally more susceptible to price volatility resulting from market
interest rate changes. In addition, the volatility of Ginnie Mae bonds due to
changes in market interest rates may differ from municipal bonds of comparable
coupon and maturity because bonds of the sensitivity of Ginnie Mae prepayment
experience to change in interest rates.

ADDITIONAL INFORMATION ON THE PURCHASE AND REDEMPTION OF FUND SHARES

  As described in the Prospectus, the Funds provide you with alternative ways
of purchasing Fund shares based upon your individual investment needs and
preferences.

  Each class of shares of a Fund represents an interest in the same portfolio
of investments. Each class of shares is identical in all respects except that
each class bears its own class expenses, including distribution and
administration expenses, and each class has exclusive voting rights with
respect to any distribution or service plan applicable to its shares. As a
result of the differences in the expenses borne by each class of shares, net
income per share, dividends per share and net asset value per share will vary
among a Fund's classes of shares.

  Shareholders of each class will share expenses proportionately for services
that are received equally by all shareholders. A particular class of shares
will bear only those expenses that are directly attributable to that class,
where the type or amount of services received by a class varies from one class
to another. For example, class-specific expenses generally will include
distribution and service fees.

  The minimum initial investment is $3,000 per fund share class ($50 if you
establish a systematic investment plan) and may be lower for accounts opened
through fee-based programs for which the program sponsor has established a
single master account with the fund's transfer agent and performs all sub-
accounting services related to that account.

  Class A Shares may be purchased at a public offering price equal to the
applicable net asset value per share plus an up-front sales charge imposed at
the time of purchase as set forth in the Prospectus. Shareholders may qualify
for a reduced sales charge, or the sales charge may be waived in its entirety,
as described below. Class A Shares are also subject to an annual service fee of
 .20%. See "Distribution and Service Plans." Set forth below is an example of
the method of computing the offering price of the Class A shares of a Fund. The
example assumes a purchase on April 30, 2000 of Class A shares from the Nuveen
Insured Municipal Bond Fund aggregating less than $50,000 subject to the
schedule of sales charges set forth in the Prospectus at a price based upon the
net asset value of the Class A shares.

Reduction or Elimination of Up-Front Sales Charge on Class A Shares

  Rights of Accumulation. You may qualify for a reduced sales charge on a
purchase of Class A Shares of any Fund if the amount of your purchase, when
added to the value that day of all of your prior purchases of shares of any
Fund or of another Nuveen Mutual Fund, or Nuveen exchange-traded fund, or units
of a Nuveen Defined Portfolio, on which an up-front sales charge or ongoing
distribution fee is imposed, or is normally imposed, falls within the amounts
stated in the Class A Sales Charges and Commissions table in "How You Can Buy
and Sell Shares" in the Prospectus. You or your financial advisor must notify
Nuveen or the Fund's transfer agent of any cumulative discount whenever you
plan to purchase Class A Shares of a Fund that you wish to qualify for a
reduced sales charge.

  Letter of Intent. You may qualify for a reduced sales charge on a purchase of
Class A Shares of any Fund if you plan to purchase Class A Shares of Nuveen
Mutual Funds over the next 13 months and the total amount of your purchases
would, if purchased at one time, qualify you for one of the reduced sales
charges shown in the Class A Sales Charges and Commissions table in "How You
Can Buy and Sell Shares" in the Prospectus. In order to take advantage of this
option, you must complete the applicable section of the Application Form or
sign and deliver either to an Authorized Dealer or to the Fund's transfer agent
a written Letter of Intent in a form acceptable to Nuveen. A Letter of Intent
states that you intend, but are not obligated, to purchase over the next 13
months a stated total amount of Class A shares that would qualify you for a
reduced sales charge shown above. You may count shares of a Nuveen Mutual Fund
that you already own on which you paid an up-front sales charge or an ongoing
distribution fee and any Class B or Class C Shares of a Nuveen Mutual Fund that
you purchase over the next 13 months towards completion of your investment
program, but you will receive a reduced sales charge only on new Class A Shares
you purchase with a sales charge over the 13 months. You cannot count towards
completion of your investment program Class A Shares that you purchase without
a sales charge through investment of distributions from a Nuveen Mutual Fund,
Nuveen Exchange-Traded Fund or a Nuveen Defined Portfolio, or otherwise.

  By establishing a Letter of Intent, you agree that your first purchase of
Class A Shares of a Fund following execution of the Letter of Intent will be at
least 5% of the total amount of your intended purchases. You further agree that
shares representing 5% of the total amount of your intended purchases will be
held in escrow pending completion of these purchases. All dividends and capital
gains distributions on Class A Shares held in escrow will be credited to your
account. If total purchases, less redemptions, prior to the expiration of the
13 month period equal or exceed the amount specified in your Letter of Intent,
the Class A Shares held in escrow will be transferred to your account. If the
total purchases, less redemptions, exceed the amount specified in your Letter
of Intent and thereby qualify for a lower sales charge than the sales charge
specified in your Letter of Intent, you will receive this lower sales charge
retroactively, and the difference between it and the higher sales charge paid
will be used to purchase additional Class A Shares on your behalf. If the total
purchases, less redemptions, are less than the amount specified, you must pay
Nuveen an amount equal to the difference between the amounts paid for these
purchases and the amounts which would have been paid if the higher sales charge
had been applied. If you do not pay the additional amount within 20 days after
written request by Nuveen or your financial adviser, Nuveen will redeem an
appropriate number of your escrowed Class A Shares to meet the required
payment. By establishing a Letter of Intent, you irrevocably appoint Nuveen as
attorney to give instructions to redeem any or all of your escrowed shares,
with full power of substitution in the premises.

  You or your financial adviser must notify Nuveen or the Fund's transfer agent
whenever you make a purchase of Fund shares that you wish to be covered under
the Letter of Intent option.

  Reinvestment of Nuveen Defined Portfolio Distributions. You may purchase
Class A Shares without an up-front sales charge by reinvestment of
distributions from any of the various Defined Portfolios sponsored by Nuveen.
There is no initial or subsequent minimum investment requirement for such
reinvestment purchases.


                                      S-46
<PAGE>

  Group Purchase Programs. If you are a member of a qualified group, you may
purchase Class A Shares of any Fund or of another Nuveen Mutual Fund at the
reduced sales charge applicable to the group's purchases taken as a whole. A
"qualified group" is one which has previously been in existence, has a purpose
other than investment, has ten or more participating members, has agreed to
include Fund sales publications in mailings to members and has agreed to comply
with certain administrative requirements relating to its group purchases.

  Under any group purchase program, the minimum initial investment in Class A
Shares of any particular Fund or portfolio for each participant is $50,
provided that a group invests at least $3,000 and, the minimum monthly
investment in Class A Shares of any particular Fund or portfolio by each
participant in the program is $50. No certificate will be issued for any
participant's account. All dividends and other distributions by a Fund will be
reinvested in additional Class A Shares of the same Fund. No participant may
utilize a systematic withdrawal program.

  To establish a group purchase program, both the group itself and each
participant must fill out the appropriate application materials, which the
group administrator may obtain from the group's financial adviser, by calling
Nuveen toll-free at (800) 257-8787.

  Reinvestment of Redemption Proceeds from Unaffiliated Funds Subject to Merger
or Closure. You may also purchase Class A Shares at net asset value without a
sales charge if the purchase takes place through a broker-dealer and represents
the reinvestment of the proceeds of the redemption of shares of one or more
registered investment companies not affiliated with Nuveen that are subject to
merger or closure. You must provide appropriate documentation that the
redemption occurred not more than one year prior to the reinvestment of the
proceeds in Class A Shares, and that you either paid an up-front sales charge
or were subject to a contingent deferred sales charge in respect of the
redemption of such shares of such other investment company.

  Class A Shares of a Fund may be purchased at net asset value without a sales
charge by the following categories of investors:

  . investors purchasing $1,000,000 or more; Nuveen may pay Authorized
    Dealers on Class A sales of $1.0 million and above up to an additional
    0.25% of the purchase amounts.

  . officers, trustees and former trustees of the Nuveen and former Flagship
    Funds;
  . bona fide, full-time and retired employees and directors of Nuveen, any
    parent company of Nuveen, and subsidiaries thereof, or their immediate
    family members;
  . any person who, for at least 90 days, has been an officer, director or
    bona fide employee of any Authorized Dealer, or their immediate family
    members;
  . officers and directors of bank holding companies that make Fund shares
    available directly or through subsidiaries or bank affiliates or their
    immediate family members;
  . bank or broker-affiliated trust departments investing funds over which
    they exercise exclusive discretionary investment authority and that are
    held in a fiduciary, agency, advisory, custodial or similar capacity;
  . investors purchasing on a periodic fee, asset-based fee or no transaction
    fee basis through a broker-dealer sponsored mutual fund purchase program;
  . clients of investment advisers, financial planners or other financial
    intermediaries that charge periodic or asset-based fees for their
    services;
   any eligible employer-sponsored qualified defined contribution retirement
   plan. Eligible plans are those with at least 25 employees and which either
   (a) make an initial purchase of one or more Nuveen Mutual Funds
   aggregating $500,000 or more or (b) execute a Letter of Intent to purchase
   in the aggregate

                                      S-47
<PAGE>


   $500,000 or more of fund shares. Nuveen will pay Authorized Dealers a
   sales commission on such purchases equal to 1% of the first $2.5 million,
   plus 0.50% of the next $2.5 million, plus 0.25% of any amount purchased
   over $5.0 million. For this category of investors a contingent deferred
   sales charge of 1% will be assessed on redemptions within 18 months of
   purchase, unless waived. Municipal bond funds are not a suitable
   investment for individuals investing in retirement plans.

  Also, investors will be able to buy Class A shares at net asset value by
using the proceeds of sales of Nuveen Exchange-Traded fund shares or the
termination/maturity proceeds from Nuveen Defined Portfolios. You must provide
Nuveen appropriate documentation that the fund sale or Defined Portfolio
termination/maturity occurred not more than one year prior to reinvestment. In
addition, investors also may buy Class A shares at net asset value without a
sales charge by directing their monthly dividends from Nuveen Exchange-Traded
funds.

  Holders of Class C Shares acquired on or before January 31, 1997 can convert
those shares to Class A Shares of the same fund at the shareholder's
affirmative request six years after date of purchase. Holders of Class C Shares
must submit their request to the transfer agent no later than the last business
day of the 71st month following the month in which they purchased their shares.
Holders of Class C Shares purchased after that date will not have the option to
convert those shares to Class A Shares.

  Class B Shares will automatically convert to Class A Shares eight years after
purchase. The purpose of the conversion is to limit the distribution fees you
pay over the life of your investment. All conversions will be done at net asset
value without the imposition of any sales load, fee, or other charge, so that
the value of each shareholder's account immediately before conversion will be
the same as the value of the account immediately after conversion. Class B
Shares acquired through reinvestment of distributions will convert into Class A
Shares based on the date of the initial purchase to which such shares relate.
For this purpose, Class B Shares acquired through reinvestment of distributions
will be attributed to particular purchases of Class B Shares in accordance with
such procedures as the Board of Trustees may determine from time to time. Class
B Shares that are converted to Class A Shares will remain subject to an annual
service fee that is identical in amount for both Class B Shares and Class A
Shares. Since net asset value per share of the Class B Shares and the Class A
Shares may differ at the time of conversion, a shareholder may receive more or
fewer Class A Shares than the number of Class B Shares converted. Any
conversion of Class B Shares into Class A Shares will be subject to the
continuing availability of an opinion of counsel or a private letter ruling
from the Internal Revenue Service to the effect that the conversion of shares
would not constitute a taxable event under federal income tax law. Conversion
of Class B Shares into Class A Shares might be suspended if such an opinion or
ruling were no longer available.

  Any Class A Shares purchased pursuant to a special sales charge waiver must
be acquired for investment purposes and on the condition that they will not be
transferred or resold except through redemption by the Funds. You or your
financial advisor must notify Nuveen or the Fund's transfer agent whenever you
make a purchase of Class A Shares of any Fund that you wish to be covered under
these special sales charge waivers.

  Class A Shares of any Fund may be issued at net asset value without a sales
charge in connection with the acquisition by a Fund of another investment
company. All purchases under the special sales charge waivers will be subject
to minimum purchase requirements as established by the Funds.

  In determining the amount of your purchases of Class A Shares of any Fund
that may qualify for a reduced sales charge, the following purchases may be
combined: (1) all purchases by a trustee or other fiduciary for a single trust,
estate or fiduciary account; (2) all purchases by individuals and their
immediate family members (i.e., their spouses, parents, children, grandparents,
grandchildren, parents-in-law, sons-and daughters-in-law, siblings, a sibling's
spouse, and a spouse's siblings); or (3) all purchases made through a group
purchase program as described above.

  Class R Share Purchase Eligibility. Class R Shares are available for
purchases of $10 million or more and for purchases using dividends and capital
gains distributions on Class R Shares. Class R Shares also are available for
the following categories of investors:

  . officers, trustees and former trustees of the Nuveen and former Flagship
    Funds and their immediate family members or trustees/directors of any
    fund, sponsored by Nuveen, any parent company of Nuveen and subsidiaries
    thereof and their immediate family members;
  . bona fide, full-time and retired employees and directors of Nuveen, any
    parent company of Nuveen, and subsidiaries thereof, or their immediate
    family members;

  . officers, directors or bona fide employees of any investment advisory
    partner of Nuveen that provides sub-advisory services for a Nuveen
    product, or their immediate family members;
  . any person who, for at least 90 days, has been an officer, director or
    bona fide employee of any Authorized Dealer, or their immediate family
    members;
  . officers and directors of bank holding companies that make Fund shares
    available directly or through subsidiaries or bank affiliates, or their
    immediate family members;
  . bank or broker-affiliated trust departments investing funds over which
    they exercise exclusive discretionary investment authority and that are
    held in a fiduciary, agency, advisory, custodial or similar capacity;
  . investors purchasing on a periodic fee, asset-based fee or no transaction
    fee basis through a broker-dealer sponsored mutual fund purchase program;

  . clients of investment advisors, financial planners or other financial
    intermediaries that charge periodic or asset-based fees for their
    services;

  Any shares purchased by investors falling within any of the first five
categories listed above must be acquired for investment purposes and on the
condition that they will not be transferred or resold except through redemption
by the fund.

  In addition, purchasers of Nuveen Defined Portfolios may reinvest their
distributions from such Defined Portfolios in Class R Shares, if, before
September 6, 1994, such purchasers of Nuveen unit investment trusts had elected
to reinvest distributions in Nuveen Fund shares (before June 13, 1995 for
Nuveen Municipal Bond Fund shares). Shareholders may exchange their Class R
Shares of any Nuveen Fund into Class R Shares of any other Nuveen Fund.

  The reduced sales charge programs may be modified or discontinued by the
Funds at any time.
  If you are eligible to purchase either Class R Shares or Class A Shares
without a sales charge at net asset value, you should be aware of the
differences between these two classes of shares. Class A Shares are subject to
an annual service fee to compensate Authorized Dealers for providing you with
ongoing account service. Class R Shares are not subject to a distribution or
service fee and, consequently, holders of Class R Shares may not receive the
sale types or levels of services from Authorized Dealers. In choosing between
Class A Shares and Class R Shares, you should weigh the benefits of the
services to be provided by Authorized Dealers against the annual service fee
imposed upon the Class A Shares.
  For more information about the purchase of Class A Shares or reduced sales
charge programs, or to obtain the required application forms, call Nuveen toll-
free at (800) 257-8787.

Reduction or Elimination of Contingent Deferred Sales Charge

  Class A Shares are normally redeemed at net asset value, without any
Contingent Deferred Sales Charge ("CDSC"). However, in the case of Class A
Shares purchased at net asset value on or after July 1, 1996 because

                                      S-49
<PAGE>

the purchase amount exceeded $1 million, where the Authorized Dealer did not
waive the sales commission, a CDSC of 1% is imposed on any redemption within 18
months of purchase. In the case of Class B Shares redeemed within six years of
purchase, a CDSC is imposed, beginning at 5% for redemptions within the first
year, declining to 4% for redemptions within years two and three, and declining
by 1% each year thereafter until disappearing after the sixth year. Class C
Shares are redeemed at net asset value, without any CDSC, except that a CDSC of
1% is imposed upon redemption of Class C Shares that are redeemed within 12
months of purchase.

  In determining whether a CDSC is payable, a Fund will first redeem shares not
subject to any charge and then will redeem shares held for the longest period,
unless the shareholder specifies another order. No CDSC is charged on shares
purchased as a result of automatic reinvestment of dividends or capital gains
paid. In addition, no CDSC will be charged on exchanges of shares into another
Nuveen Mutual Fund or Nuveen money market fund. The holding period is
calculated on a monthly basis and begins the first day of the month in which
the order for investment is received. The CDSC is calculated based on the lower
of the redeemed shares' cost or net asset value at the time of the redemption
and is deducted from the redemption proceeds. Nuveen receives the amount of any
CDSC shareholders pay. If Class A or Class C shares subject to a CDSC are
exchanged for shares of a Nuveen money market fund, the CDSC would be imposed
on the subsequent redemption of those money market fund shares, and the period
during which the shareholder holds the money market fund shares would be
counted in determining the remaining duration of the CDSC. The Fund may elect
not to so count the period during which the shareholder held the money market
fund shares, in which event the amount of any applicable CDSC would be reduced
in accordance with applicable rules by the amount of any 12b-1 plan payments to
which those money market funds shares may be subject.

  The CDSC may be waived or reduced under the following seven special
circumstances: 1) redemptions within one year following the death or
disability, as defined in Section 72(m)(7) of the Internal Revenue Code of
1986, as amended, of a shareholder; 2) in whole or in part for redemptions of
shares by shareholders with accounts in excess of specified breakpoints that
correspond to the breakpoints under which the up-front sales charge on Class A
Shares is reduced pursuant to Rule 22d-1 under the Act; 3) redemptions of
shares purchased under circumstances or by a category of investors for which
Class A Shares could be purchased at net asset value without a sales charge; 4)
in connection with the exercise of a reinstatement privilege whereby the
proceeds of a redemption of a Fund's shares subject to a sales charge are
reinvested in shares of certain Funds within a specified number of days; 5) in
connection with the exercise of a Fund's right to redeem all shares in an
account that does not maintain a certain minimum balance or that the applicable
board has determined may have material adverse consequences to the shareholders
of such Fund; 6) involuntary redemptions caused by operation of law; 7)
redemptions in connection with a payment of account or plan fees; 8)
redemptions made pursuant to a Fund's systematic withdrawal plan, up to 1%
monthly, 3% quarterly, 6% semiannually or 12% annually of an account's net
asset value depending on the frequency of the plan as designated by the
shareholder; and 9) redemptions of Classes A, B or C Shares if the proceeds are
transferred to an account managed by another Nuveen Adviser and the adviser
refunds the advanced service and distribution fees to Nuveen. If a Fund waives
or reduces the CDSC, such waiver or reduction would be uniformly applied to all
Fund shares in the particular category. In waiving or reducing a CDSC, the
Funds will comply with the requirements of Rule 22d-1 of the Investment Company
Act of 1940, as amended.

Shareholder Programs

Exchange Privilege

  You may exchange shares of a class of the Fund for shares of the same class
of any other Nuveen Mutual Fund with reciprocal exchange privileges, at net
asset value without a sales charge, by sending a written request to the Fund,
c/o Nuveen Investor Services, P.O. Box 5186, Bowling Green Station, New York,
NY 10274-5186.

                                      S-50
<PAGE>


Similarly, Class A, Class B, Class C and Class R Shares of other Nuveen Mutual
Funds may be exchanged for the same class of shares of the Fund at net asset
value without a sales charge. Exchanges of shares from any Nuveen money market
fund will be made into Class A Shares, Class B Shares, Class C Shares or Class
R Shares (if eligible) of the Fund at the public offering price. If, however, a
sales charge has previously been paid on the investment represented by the
exchanged shares (i.e., the shares to be exchanged were originally issued in
exchange for shares on which a sales charge was paid), the exchange of shares
from a Nuveen money market fund will be made into shares of the Fund at net
asset value. All shares may be exchanged for shares of any Nuveen Money market
fund.

  If you exchange shares subject to a CDSC, no CDSC will be charged at the time
of the exchange. However, if you subsequently redeem the shares acquired
through the exchange, the redemption may be subject to a CDSC, depending on
when you purchased your original shares and the CDSC schedule of the fund from
which you exchanged your shares.

  The shares to be purchased must be offered in your state of residence and you
must have held the shares you are exchanging for at least 15 days. The total
value of exchanged shares must at least equal the minimum investment
requirement of the Nuveen Mutual Fund being purchased. For federal income tax
purposes, any exchange constitutes a sale and purchase of shares and may result
in capital gain or loss. Before making any exchange, you should obtain the
Prospectus for the Nuveen Mutual Fund you are purchasing and read it carefully.
If the registration of the account for the Fund you are purchasing is not
exactly the same as that of the fund account from which the exchange is made,
written instructions from all holders of the account from which the exchange is
being made must be received, with signatures guaranteed by a member of an
approved Medallion Guarantee Program or in such other manner as may be
acceptable to the Fund. You may also exchange shares by telephone if you
authorize telephone exchanges by checking the applicable box on the Application
Form or by calling Nuveen Investor Services toll-free 800-257-8787 to obtain an
authorization form. The exchange privilege may be modified or discontinued by
the Fund at any time.

  The exchange privilege is not intended to permit the Fund to be used as a
vehicle for short-term trading. Excessive exchange activity may interfere with
portfolio management, raise expenses, and otherwise have an adverse effect on
all shareholders. In order to limit excessive exchange activity and in other
circumstances where Fund management believes doing so would be in the best
interest of the Fund, the Fund reserves the right to revise or terminate the
exchange privilege, or limit the amount or number of exchanges or reject any
exchange. Shareholders would be notified of any such action to the extent
required by law.

Reinstatement Privilege

  If you redeemed Class A, Class B or Class C Shares of the Fund or any other
Nuveen Mutual Fund that were subject to a sales charge or a CDSC, you have up
to one year to reinvest all or part of the full amount of the redemption in the
same class of shares of the Fund at net asset value. This reinstatement
privilege can be exercised only once for any redemption, and reinvestment will
be made at the net asset value next calculated after reinstatement of the
appropriate class of Fund shares. If you reinstate shares that were subject to
a CDSC, your holding period as of the redemption date also will be reinstated
for purposes of calculating a CDSC and the CDSC paid at redemption will be
refunded. The federal income tax consequences of any capital gain realized on a
redemption will not be affected by reinstatement, but a capital loss may be
disallowed in whole or in part depending on the timing, the amount of the
reinvestment and the fund from which the redemption occurred.

General Matters

  The Funds may encourage registered representatives and their firms to help
apportion their assets among bonds, stocks and cash, and may seek to
participate in programs that recommend a portion of their assets be invested in
tax-free, fixed income securities.

                                      S-51
<PAGE>

  In addition to the types of compensation to dealers to promote sales of fund
shares that are described in the prospectus, Nuveen may from time to time make
additional reallowances only to certain authorized dealers who sell or are
expected to sell certain minimum amounts of shares of the Nuveen Mutual Funds
during specified time periods. Promotional support may include providing sales
literature to and holding informational or educational programs for the benefit
of such Authorized Dealers' representatives, seminars for the public, and
advertising and sales campaigns. Nuveen may reimburse a participating
Authorized Dealer for up to one-half of specified media costs incurred in the
placement of advertisements which jointly feature the Authorized Dealer and
Nuveen Funds and Nuveen Defined Portfolios.

  Such reimbursement will be based on the number of Nuveen Fund shares sold,
the dollar amounts of such sales, or a combination of the foregoing, during the
prior calendar year according to an established schedule. Any such support or
reimbursement would be provided by Nuveen out of its own assets, and not out of
the assets of the Funds, and will not change the price an investor pays for
shares or the amount that a Fund will receive from such a sale.

  To help advisors and investors better understand and most efficiently use the
Fund to reach their investment goals, the Funds may advertise and create
specific investment programs and systems. For example, this may include
information on how to use the Funds to accumulate assets for future education
needs or periodic payments such as insurance premiums. The Funds may produce
software or additional sales literature to promote the advantages of using the
Funds to meet these and other specific investor needs.

  The Funds have authorized one or more brokers to accept on their behalf
purchase and redemption orders. Such brokers are authorized to designate other
intermediaries to accept purchase and redemption orders on the Funds' behalf.
The Funds will be deemed to have received a purchase or redemption order when
an authorized broker or, if applicable, a broker's authorized designee accepts
the order. Customer orders received by such broker (or their designee) will be
priced at the Funds' net asset value next computed after they are accepted by
an authorized broker (or their designee). Orders accepted by an authorized
broker (or their designee) before the close of regular trading on the New York
Stock Exchange will receive that day's share price; orders accepted after the
close of trading will receive the next business day's share price.

  Exchanges of shares of a Fund for shares of a Nuveen money market fund may be
made on days when both funds calculate a net asset value and make shares
available for public purchase. Shares of the Nuveen money market funds may be
purchased on days on which the Federal Reserve Bank of Boston is normally open
for business. In addition to the holidays observed by the Fund, the Nuveen
money market funds observe and will not make fund shares available for purchase
on the following holidays: Martin Luther King's Birthday, Columbus Day and
Veterans Day.

  In addition, you may exchange Class R Shares of any Fund for Class A Shares
of the same Fund without a sales charge if the current net asset value of those
Class R Shares is at least $3,000 or you already own Class A Shares of that
Fund.

  Each Fund may suspend the right of redemption, or delay payment to redeeming
shareholders for more than seven days, when the New York Stock Exchange is
closed (not including customary weekend and holiday closings); when trading in
the markets a Fund normally uses is restricted, or the SEC determines that an
emergency exists so that trading of a Fund's portfolio securities or
determination of a Fund's net assets value is not reasonably practical; or the
SEC by order permits the suspension of the right of redemption or the delay in
payment to redeeming shareholders for more than seven days.

  The Funds have reserved the right to redeem in kind (that is, to pay
redemption requests in cash and portfolio securities, or wholly in portfolio
securities), although the Funds have no present intention to redeem in kind.
The Funds voluntarily have committed to pay in cash all requests for redemption
by any shareholder,

                                      S-52
<PAGE>

limited as to each shareholder during any ninety-day period to the lesser of
$250,000 or 1% of the net asset value of a Fund at the beginning of the ninety-
day period.

  Shares will be registered in the name of the investor or the investor's
financial advisor. A change in registration or transfer of shares held in the
name of a financial advisor may only be made by an order in good form from the
financial advisor acting on the investor's behalf. Share certificates will only
be issued upon written request to the Funds' transfer agent. No share
certificates will be issued for fractional shares.

  A fee of 1% of the current market value of any shares represented by a
certificate will be charged if the certificate is lost, stolen, or destroyed.
The fee is paid to Seaboard Surety Company for insurance of the lost, stolen,
or destroyed certificate.

  For more information on the procedure for purchasing shares of a Fund and on
the special purchase programs available thereunder, see "How to Buy Shares" in
the Prospectus.

  Nuveen serves as the principal underwriter of the shares of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution
agreement with the Nuveen Flagship Municipal Trust, dated February 1, 1997 and
last renewed on July 31, 2000 ("Distribution Agreement"). Pursuant to the
Distribution Agreement, the Trust appointed Nuveen to be its agent for the
distribution of the Funds' shares on a continuous offering basis. Nuveen sells
shares to or through brokers, dealers, banks or other qualified financial
intermediaries (collectively referred to as "Dealers"), or others, in a manner
consistent with the then effective registration statement of the Trust.
Pursuant to the Distribution Agreement, Nuveen, at its own expense, finances
certain activities incident to the sale and distribution of the Funds' shares,
including printing and distributing of prospectuses and statements of
additional information to other than existing shareholders, the printing and
distributing of sales literature, advertising and payment of compensation and
giving of concessions to Dealers. Nuveen receives for its services the excess,
if any, of the sales price of the Funds' shares less the net asset value of
those shares, and reallows a majority or all of such amounts to the Dealers who
sold the shares; Nuveen may act as such a Dealer. Nuveen also receives
compensation pursuant to a distribution plan adopted by the Trust pursuant to
Rule 12b-1 and described herein under "Distribution and Service Plan." Nuveen
receives any CDSCs imposed on redemptions of Shares.

  The aggregate amounts of underwriting commissions with respect to the sale of
Fund shares and the amount thereof retained by Nuveen were as follows (all
figures are to the nearest thousand):

DISTRIBUTION AND SERVICE PLAN

  The Funds have adopted a plan (the "Plan") pursuant to Rule 12b-1 under the
Investment Company Act of 1940, which provides that Class B Shares and Class C
Shares will be subject to an annual distribution fee, and that Class A Shares,
Class B Shares and Class C Shares will be subject to an annual service fee.
Class R Shares will not be subject to either distribution or service fees.

  The distribution fee applicable to Class B and Class C Shares under each
Fund's Plan will be payable to reimburse Nuveen for services and expenses
incurred in connection with the distribution of Class B and Class C Shares,
respectively. These expenses include payments to Authorized Dealers, including
Nuveen, who are brokers of record with respect to the Class B and Class C
Shares, as well as, without limitation, expenses of printing and distributing
prospectuses to persons other than shareholders of the Fund, expenses of
preparing, printing and distributing advertising and sales literature and
reports to shareholders used in connection with the sale of Class B and Class C
Shares, certain other expenses associated with the distribution of Class B and
Class C Shares, and any distribution-related expenses that may be authorized
from time to time by the Board of Trustees.

  The service fee applicable to Class A Shares, Class B Shares and Class C
Shares under each Fund's Plan will be payable to Authorized Dealers in
connection with the provision of ongoing account services to shareholders.
These services may include establishing and maintaining shareholder accounts,
answering shareholder inquiries and providing other personal services to
shareholders.

  Each Fund may spend up to .20 of 1% per year of the average daily net assets
of Class A Shares as a service fee under the Plan applicable to Class A Shares.
Each Fund may spend up to .75 of 1% per year of the average daily net assets of
Class B Shares as a distribution fee and up to .20 of 1% per year of the
average daily net assets of Class B Shares as a service fee under the Plan
applicable to Class B Shares. Each Fund may spend up to .55 of 1% per year of
the average daily net assets of Class C Shares as a distribution fee and up to
 .20 of 1% per year of the average daily net assets of Class C Shares as a
service fee under the Plan applicable to Class C Shares.

  For the fiscal year ended April 30, 2000, 100% of service fees and
distribution fees were paid out as compensation to authorized dealers.

  Under each Fund's Plan, the Fund will report quarterly to the Board of
Trustees for its review all amounts expended per class of shares under the
Plan. The Plan may be terminated at any time with respect to any class of
shares, without the payment of any penalty, by a vote of a majority of the
trustees who are not "interested persons" and who have no direct or indirect
financial interest in the Plan or by vote of a majority of the outstanding
voting securities of such class. The Plan may be renewed from year to year if
approved by a vote of the Board of Trustees and a vote of the non-interested
trustees who have no direct or indirect financial interest in the Plan cast in
person at a meeting called for the purpose of voting on the Plan. The Plan may
be continued only if the trustees who vote to approve such continuance
conclude, in the exercise of reasonable business judgment and in light of their
fiduciary duties under applicable law, that there is a reasonable likelihood
that the Plan will benefit the Fund and its shareholders. The Plan may not be
amended to increase materially the cost which a class of shares may bear under
the Plan without the approval of the shareholders of the affected class, and
any other material amendments of the Plan must be approved by the non-
interested trustees by a vote cast in person at a meeting called for the
purpose of considering such amendments. During the continuance of the Plan, the
selection and nomination of the non-interested trustees of the Trust will be
committed to the discretion of the non-interested trustees then in office.

APPENDIX A

Ratings of Investments

  Standard & Poor's Ratings Group--A brief description of the applicable
Standard & Poor's Ratings Group ("S&P") rating symbols and their meanings (as
published by S&P) follows:

                              Long Term Debt

  An S&P corporate or municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers,
or lessees.

  The debt rating is not a recommendation to purchase, sell, or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor.

  The ratings are based on current information furnished by the issuer or
obtained by S&P from other sources it considers reliable. S&P does not perform
an audit in connection with any rating and may, on occasion, rely on unaudited
financial information. The ratings may be changed, suspended, or withdrawn as a
result of changes in, or unavailability of, such information, or based on other
circumstances.

  The ratings are based, in varying degrees, on the following considerations:

    1. Likelihood of default--capacity and willingness of the obligor as to
  the timely payment of interest and repayment of principal in accordance
  with the terms of the obligation;

    2. Nature of and provisions of the obligation;

    3. protection afforded by, and relative position of, the obligation in
  the event of bankruptcy, reorganization, or other arrangement under the
  laws of bankruptcy and other laws affecting creditors' rights.

Investment Grade

AAA

   Debt rated "AAA' has the highest rating assigned by S&P. Capacity to pay
   interest and repay principal is extremely strong.

AA

   Debt rated "AA' has a very strong capacity to pay interest and repay
   principal, and differs from the highest-rated issues only in small
   degree.

A

   Debt rated "A' has a strong capacity to pay interest and repay principal
   although it is somewhat more susceptible to the adverse effects of
   changes in circumstances and economic conditions than debt in higher-
   rated categories.

BBB

   Debt rated "BBB' is regarded as having an adequate capacity to pay
   interest and repay principal. Whereas it normally exhibits adequate
   protection parameters, adverse economic conditions or changing
   circumstances are more likely to lead to a weakened capacity to pay
   interest and repay principal for debt in this category than in higher-
   rated categories.

Speculative Grade Rating

  Debt rated "BB,' "B,' "CCC,' "CC' and "C' is regarded as having predominantly
speculative characteristics, with respect to capacity to pay interest and repay
principal. "BB' indicates the least degree of speculation and "C' the highest.
While such debt will likely have some quality and protective characteristics
these are outweighed by major uncertainties or major exposures to adverse
conditions.

                                      A-1
<PAGE>


BB

   Debt rated "BB' has less near-term vulnerability to default than other
   speculative issues. However, it faces major ongoing uncertainties or
   exposure to adverse business, financial, or economic conditions which
   could lead to inadequate capacity to meet timely interest and principal
   payments. The "BB' rating category is also used for debt subordinated to
   senior debt that is assigned an actual or implied "BBB-' rating.

B

   Debt rated "B' has a greater vulnerability to default but currently has
   the capacity to meet interest payments and principal repayments. Adverse
   business, financial, or economic conditions will likely impair capacity
   or willingness to pay interest and repay principal. The "B' rating
   category is also used for debt subordinated to senior debt that is
   assigned an actual or implied "BB' or "BB-' rating.

CCC

   Debt rated "CCC' has a currently identifiable vulnerability to default
   and is dependent upon favorable business, financial, and economic
   conditions to meet timely payment of interest and repayment of principal.
   In the event of adverse business, financial, or economic conditions, it
   is not likely to have the capacity to pay interest and repay principal.

   The "CCC' rating category is also used for debt subordinated to senior
   debt that is assigned an actual or implied "B' or "B-' rating.

CC

   The rating "CC' typically is applied to debt subordinated to senior debt
   that is assigned an actual or implied "CCC' debt rating.

C

   The rating "C' typically is applied to debt subordinated to senior debt
   which is assigned an actual or implied "CCC-' debt rating. The "C' rating
   may be used to cover a situation where a bankruptcy petition has been
   filed, but debt service payments are continued.

CI

   The rating "CI' is reserved for income bonds on which no interest is
   being paid.

D

   Debt rated "D' is in payment default. The "D' rating category is used
   when interest payments or principal payments are not made on the date due
   even if the applicable grace period has not expired, unless S&P believes
   that such payments will be made during such grace period. The "D' rating
   also will be used upon the filling of a bankruptcy petition if debt
   service payments are jeopardized.

   Plus (+) or Minus (-): the ratings from "AA' to "CCC' may be modified by
   the addition of a plus or minus sign to show relative standing within the
   major rating categories.

   Provisional Ratings: the letter "p" indicates that the rating is
   provisional. A provisional rating assumes the successful completion of
   the project financed by the debt being rated and indicates that payment
   of debt service requirements is largely or entirely dependent upon the
   successful and timely completion of the project. This rating, however,
   while addressing credit quality subsequent to completion of the project,
   makes no comment on the likelihood of, or the risk of default upon
   failure of, such completion. The investor should exercise judgment with
   respect to such likelihood and risk.

L

   The letter "L' indicates that the rating pertains to the principal amount
   of those bonds to the extent that the underlying deposit collateral is
   federally insured by the Federal Savings & Loan Insurance Corp. or the
   Federal Deposit Insurance Corp.* and interest is adequately
   collateralized. In the case of certificates of deposit, the letter "L'
   indicates that the deposit, combined with other deposits being held in
   the same right and capacity, will be honored for principal and accrued
   pre-default interest up to the federal insurance limits within 30 days
   after closing of the insured institution or, in the event that the
   deposit is assumed by a successor insured institution, upon maturity.

NR

   Indicates no rating has been requested, that there is insufficient
   information on which to base a rating, or that S&P does not rate a
   particular type of obligation as a matter of policy.

                                      A-2

                             Commercial Paper

  An S&P commercial paper rating is a current assessment of the likelihood of
timely payment of debt having an original maturity of no more than 365 days.

  Ratings are graded into several categories, ranging from "A-1" for the
highest quality obligations to "D" for the lowest. These categories are as
follows:

A-1

   This designation indicates that the degree of safety regarding timely
   payment is strong. Those issues determined to possess extremely strong
   safety characteristics are denoted with a plus sign (+) designation.

A-2

   Capacity for timely payment on issues with this designation is
   satisfactory. However, the relative degree of safety is not as high as
   for issues designated "A-1."

A-3

   Issues carrying this designation have adequate capacity for timely
   payment. They are, however, somewhat more vulnerable to the adverse
   effects of changes in circumstances than obligations carrying the higher
   designations.

B

   Issues rated "B" are regarded as having only speculative capacity for
   timely payment.

C

   This rating is assigned to short-term debt obligations with a doubtful
   capacity for payment.

D

   Debt rated "D" is in payment default. The "D" rating category is used
   when interest payments or principal payments are not made on the date
   due, even if the applicable grace period has not expired, unless S&P
   believes that such payments will be made during such grace period.

  A commercial rating is not a recommendation to purchase, sell, or hold a
security inasmuch as it does not comment as to market price or suitability for
a particular investor. The ratings are based on current information furnished
to S&P by the issuer or obtained by S&P from other sources it considers
reliable. S&P does not perform an audit in connection with any rating and may,
on occasion, rely on unaudited financial information. the ratings may be
changed, suspended, or withdrawn as a result of changes in or unavailability of
such information or based on other circumstances.

  Moody's Investors Service, Inc.--A brief description of the applicable
Moody's Investors Service, Inc. ("Moody's") rating symbols and their meanings
(as published by Moody's) follows:

                              Long Term Debt

Aaa

   Bonds which are rated Aaa are judged to be of the best quality. They
   carry the smallest degree of investment risk and are generally referred
   to as "gilt edge." Interest payments are protected by a large or by an
   exceptionally stable margin and principal is secure. While the various
   protective elements are likely to change, such changes as can be
   visualized are mostly unlikely to impair the fundamentally strong
   position of such issues.

Aa

   Bonds which are rated Aa are judged to be of high quality by all
   standards. Together with the Aaa group they comprise what are generally
   known as high grade bonds. They are rated lower than the best bonds
   because margins of protection may not be as large as in Aaa securities or
   fluctuation of protective elements may be of greater amplitude or there
   may be other elements present which make the long-term risks appear
   somewhat larger than in Aaa securities.

A

   Bonds which are rated A possess many favorable investment attributes and
   are to be considered as upper medium grade obligations. Factors giving
   security to principal and interest are considered adequate, but elements
   may be present which suggest a susceptibility to impairment sometime in
   the future.

                                      A-3
<PAGE>


Baa

   Bonds which are rated Baa are considered as medium grade obligations,
   i.e., they are neither highly protected nor poorly secured. Interest
   payments and principal security appear adequate for the present, but
   certain protective elements may be lacking or may be characteristically
   unreliable over any great length of time. Such bonds lack outstanding
   investment characteristics and in fact have speculative characteristics
   as well.

Ba

   Bonds which are rated Ba are judged to have speculative elements; their
   future can not be considered as well assured. Often the protection of
   interest and principal payments may be very moderate and thereby, not
   well safeguarded during both good and bad times over the future.
   Uncertainty of position characterizes bonds in this class.

B

   Bonds which are rated B generally lack characteristics of the desirable
   investment. Assurance of interest and principal payments or of
   maintenance of other terms of the contract over any long period of time
   may be small.

Caa

   Bonds which are rated Caa are of poor standing. Such issues may be in
   default, or there may be present elements of danger with respect to
   principal or interest.

Ca

   Bonds which are rated Ca represent obligations which are speculative in a
   high degree. Such issues are often in default or have other marked
   shortcomings.

C

   Bonds which are rated C are the lowest rated class of bonds, and issues
   so rated can be regarded as having extremely poor prospects of ever
   attaining any real investment standing.

   Bonds for which the security depends upon the completion of some act or
   the fulfillment of some condition are rated conditionally. These are
   bonds secured by (a) earnings of projects under construction, (b)
   earnings of projects unseasoned in operation experience, (c) rentals
   which begin when facilities are completed, or (d) payments to which some
   other limiting condition attaches. Parenthetical rating denotes probable
   credit stature upon completion of construction or elimination of basis of
   condition.

  Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa1,
A1, Baa1, Ba1, and B1.

                             Commercial Paper

  Issuers rated Prime-1 (or related supporting institutions) have a superior
capacity for repayment of senior short-term promissory obligations. Prime-1
repayment capacity will often be evidenced by many of the following
characteristics:

  --Leading market positions in well-established industries.

  --High rates of return on funds employed.

  --Conservative capitalization structure with moderate reliance on debt and
   ample asset protection.

  --Broad margins in earnings coverage of fixed financial charges and high
   internal cash generation.

  --Well-established access to a range of financial markets and assured
   sources of alternate liquidity.

  Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of senior short-term promissory obligations. This will
normally be evidenced by many of the characteristics cited above but to a
lesser degree. Earnings trends and coverage ratios, while sound, may be more
subject to variation. Capitalization characteristics, while still appropriate,
may be more affected by external conditions. Ample alternate liquidity is
maintained.

                                      A-4
<PAGE>


  Issuers rated Prime-3 (or related supporting institutions) have an acceptable
capacity for repayment of senior short-term promissory obligations. The effect
of industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial
leverage.

  Issuers rated Not Prime do not fall within any of the Prime rating
categories.


  On June 1, 2000, Fitch IBCA, Inc. and Duff & Phelps, Inc. merged. The
combined company name is Fitch, Inc. ("Fitch") and both companies' ratings
systems have been combined into a single rating system. A brief description of
the applicable Fitch ratings symbols and meanings (as published by Fitch)
follows:

                              Long Term Debt

  Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.

  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength and credit quality.

  Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guaranties unless otherwise indicated.

  Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.

  Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.

  Fitch ratings are based on information obtained from issuers, other obligors,
underwriters, their experts, and other sources Fitch believes to be reliable.
Fitch does not audit or verify the truth or accuracy of such information.
Ratings may be changed, suspended or withdrawn as a result of changes in, or
the unavailability of, information or for other reasons.

AAA

   Bonds considered to be investment grade and of the highest credit
   quality. The obligor has an exceptionally strong ability to pay interest
   and repay principal, which is unlikely to be affected by reasonably
   foreseeable events.

AA

   Bonds considered to be investment grade and of very high credit quality.
   The obligor's ability to pay interest and repay principal is very strong,
   although not quite as strong as bonds rated "AAA". Because bonds rated in
   the "AAA" and "AA" categories are not significantly vulnerable to
   foreseeable future developments, short-term debt of the issuers is
   generally rated "F-1+".

A

   Bonds considered to be investment grade and of high credit quality. The
   obligor's ability to pay interest and repay principal is considered to be
   strong but may be more vulnerable to adverse changes in economic
   conditions and circumstances than bonds with higher ratings.

BBB

   Bonds considered to be investment grade and of good credit quality. The
   obligor's ability to pay interest and repay principal is considered to be
   adequate. Adverse changes in economic conditions and circumstances,
   however, are more likely to have adverse impact on these bonds and,
   therefore, impair

                                      A-5
<PAGE>


   timely payment. The likelihood that the ratings of these bonds will fall
   below investment grade is higher than for bonds with higher ratings.

  Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
("BB" to "C") represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or
liquidation.

  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength.

  Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories can not fully reflect the
differences in the degrees of credit risk.

BB

   Bonds are considered speculative. The obligor's ability to pay interest
   and repay principal may be affected over time by adverse economic
   changes. However, business and financial alternatives can be identified
   which could assist the obligor in satisfying its debt service
   requirements.

B

   Bonds are considered highly speculative. While bonds in this class are
   currently meeting debt service requirements, the probability of continued
   timely payment of principal and interest reflects the obligor's limited
   margin of safety and the need for reasonable business and economic
   activity throughout the life of the issue.

CCC

   Bonds have certain identifiable characteristics which, if not remedied,
   may lead to default. The ability to meet obligations requires an
   advantageous business economic environment.

CC

   Bonds are minimally protected. Default in payment of interest and/or
   principal seems probable over time.

C

   Bonds are in imminent default in payment of interest or principal.

DDD DD and D

   Bonds are in default on interest and/or principal payments. Such bonds DD
   are extremely speculative and should be valued on the basis of their and
   D ultimate recovery value in liquidation or reorganization of the
   obligor. "DDD" represents the highest potential for recovery of these
   bonds, and "D" represents the lowest potential for recovery.

                               Short-Term Ratings

  Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally up to three years, including
commercial paper, certificate of deposit, medium-term notes, and municipal and
investment notes.

  The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.

F-1+

   Exceptionally Strong Credit Quality Issues assigned this rating are
   regarded as having the strongest degree of assurance for timely payment.

F-1

   Very Strong Credit Quality Issues assigned this rating reflect an
   assurance of timely payment only slightly less in degree than issues
   rated "F-1+".

                                      A-6
<PAGE>


F-2

   Good Credit Quality Issues assigned this rating have a satisfactory
   degree of assurance for timely payment, but the margin of safety is not
   as great as for issues assigned "F-1+" and "F-1" ratings.

F-3

   Fair Credit Quality Issues assigned this rating have characteristics
   suggesting that the degree of assurance for timely payment is adequate;
   however, near-term adverse changes could cause these securities to be
   rated below investment grade.

B

   Speculative issues assigned this rating have minimal capacity for timely
   payments and are vulnerable to near-term changes in financial and
   economic conditions.

C

   High default risk issues where default is a real possibility. Capacity
   for making timely payments is solely reliant upon a sustained, favorable
   business and economic environment.

D

   Default Issues assigned this rating are in actual or imminent payment
   default.



  Subsequent to its purchase by a Fund, an issue may cease to be rated or its
rating may be reduced below the minimum required for purchase by such Fund.
Neither event requires the elimination of such obligation from a Fund's
portfolio, but Nuveen Advisory will consider such an event in its determination
of whether the Fund should continue to hold such obligation.

APPENDIX B

DESCRIPTION OF HEDGING TECHNIQUES

  Set forth below is additional information regarding the various Funds'
defensive hedging techniques and use of repurchase agreements.

Futures and Index Transactions

  Financial Futures. A financial future is an agreement between two parties to
buy and sell a security for a set price on a future date. They have been
designed by boards of trade which have been designated "contracts markets" by
the Commodity Futures Trading Commission ("CFTC").

  The purchase of financial futures is for the purpose of hedging a Fund's
existing or anticipated holdings of long-term debt securities. When a Fund
purchases a financial future, it deposits in cash or securities an "initial
margin" of between 1% and 5% of the contract amount. Thereafter, the Fund's
account is either credited or debited on a daily basis in correlation with the
fluctuation in price of the underlying future or other requirements imposed by
the exchange in order to maintain an orderly market. The Fund must make
additional payments to cover debits to its account and has the right to
withdraw credits in excess of the liquidity, the Fund may close out its
position at any time prior to expiration of the financial future by taking an
opposite position. At closing a final determination of debits and credits is
made, additional cash is paid by or to the Fund to settle the final
determination and the Fund realizes a loss or gain depending on whether on a
net basis it made or received such payments.

  The sale of financial futures is for the purpose of hedging a Fund's existing
or anticipated holdings of long-term debt securities. For example, if a Fund
owns long-term bonds and interest rates were expected to increase, it might
sell financial futures. If interest rates did increase, the value of long-term
bonds in the Fund's portfolio would decline, but the value of the Fund's
financial futures would be expected to increase at approximately the same rate
thereby keeping the net asset value of the Fund from declining as much as it
otherwise would have.

  Among the risks associated with the use of financial futures by the Funds as
a hedging device, perhaps the most significant is the imperfect correlation
between movements in the price of the financial futures and movements in the
price of the debt securities which are the subject of the hedge.

  Thus, if the price of the financial future moves less or more than the price
of the securities which are the subject of the hedge, the hedge will not be
fully effective. To compensate for this imperfect correlation, the Fund may
enter into financial futures in a greater dollar amount than the dollar amount
of the securities being hedged if the historical volatility of the prices of
such securities has been greater than the historical volatility of the
financial futures. Conversely, the Fund may enter into fewer financial futures
if the historical volatility of the price of the securities being hedged is
less than the historical volatility of the financial futures.

  The market prices of financial futures may also be affected by factors other
than interest rates. One of these factors is the possibility that rapid changes
in the volume of closing transactions, whether due to volatile markets or
movements by speculators, would temporarily distort the normal relationship
between the markets in the financial future and the chosen debt securities. In
these circumstances as well as in periods of rapid and large price movements.
The Fund might find it difficult or impossible to close out a particular
transaction.

  Options on Financial Futures. The Funds may also purchase put or call options
on financial futures which are traded on a U.S. Exchange or board of trade and
enter into closing transactions with respect to such options to terminate an
existing position. Currently, options can be purchased with respect to
financial futures on U.S.

                                      B-1
<PAGE>

Treasury Bonds on The Chicago Board of Trade. The purchase of put options on
financial futures is analogous to the purchase of put options by a Fund on its
portfolio securities to hedge against the risk of rising interest rates. As
with options on debt securities, the holder of an option may terminate his
position by selling an option of the same Fund. There is no guarantee that such
closing transactions can be effected.

Index Contracts

  Index Futures. A tax-exempt bond index which assigns relative values to the
tax-exempt bonds included in the index is traded on the Chicago Board of Trade.
The index fluctuates with changes in the market values of all tax-exempt bonds
included rather than a single bond. An index future is a bilateral agreement
pursuant to which two parties agree to take or make delivery of an amount of
cash--rather than any security--equal to specified dollar amount times the
difference between the index value at the close of the last trading day of the
contract and the price at which the index future was originally written. Thus,
an index future is similar to traditional financial futures except that
settlement is made in cash.

  Index Options. The Funds may also purchase put or call options on U.S.
Government or tax-exempt bond index futures and enter into closing transactions
with respect to such options to terminate an existing position. Options on
index futures are similar to options on debt instruments except that an option
on an index future gives the purchaser the right, in return for the premium
paid, to assume a position in an index contract rather than an underlying
security at a specified exercise price at any time during the period of the
option. Upon exercise of the option, the delivery of the futures position by
the writer of the option to the holder of the option will be accompanied by
delivery of the accumulated balance of the writer's futures margin account
which represents the amount by which the market price of the index futures
contract, at exercise, is less than the exercise price of the option on the
index future.

  Bond index futures and options transactions would be subject to risks similar
to transactions in financial futures and options thereon as described above. No
series will enter into transactions in index or financial futures or related
options unless and until, in the Adviser's opinion, the market for such
instruments has developed sufficiently.

Repurchase Agreements

  A Fund may invest temporarily up to 5% of its assets in repurchase
agreements, which are agreements pursuant to which securities are acquired by
the Fund from a third party with the understanding that they will be
repurchased by the seller at a fixed price on an agreed date. These agreements
may be made with respect to any of the portfolio securities in which the Fund
is authorized to invest. Repurchase agreements may be characterized as loans
secured by the underlying securities. The Fund may enter into repurchase
agreements with (i) member banks of the Federal Reserve System having total
assets in excess of $500 million and (ii) securities dealers, provided that
such banks or dealers meet the creditworthiness standards established by the
Fund's Board of Trustees ("Qualified Institutions"). The Adviser will monitor
the continued creditworthiness of Qualified Institutions, subject to the
oversight of the Fund's board of trustees.

  The use of repurchase agreements involves certain risks. For example, if the
seller of securities under a repurchase agreement defaults on its obligation to
repurchase the underlying securities, as a result of its bankruptcy or
otherwise, the Fund will seek to dispose of such securities, which action could
involve costs or delays. If the seller becomes insolvent and subject to
liquidation or reorganization under applicable bankruptcy or other laws, the
Fund's ability to dispose of the underlying securities may be restricted.
Finally, it is possible that the Fund may not be able to substantiate its
interest in the underlying securities. To minimize this risk, the

                                      B-2
<PAGE>

securities underlying the repurchase agreement will be held by the custodian at
all times in an amount at least equal to the repurchase price, including
accrued interest. If the seller fails to repurchase the securities, the Fund
may suffer a loss to the extent proceeds from the sale of the underlying
securities are less than the repurchase price.

  The resale price reflects the purchase price plus an agreed upon market rate
of interest which is unrelated to the coupon rate or date of maturity of the
purchased security. The collateral is marked to market daily. Such agreements
permit the Fund to keep all its assets earning interest while retaining
"overnight" flexibility in pursuit of investments of a longer-term nature.

DEAR
Shareholder,

Chairman of the Board

As personal wealth continues to grow at an ever-increasing rate, people are
realizing the power of their investments to do good and to make a difference in
their families and communities now and for generations to come.

Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams -- the things that matter most to you and how you
can make them happen -- or make them better.


Through a well-crafted financial plan, you have the chance to shape future
generations -- to broaden your sphere of influence -- to leave your legacy.


As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality -- for yourself and future generations.

Family Wealth Management  Too often, family wealth management is thought of in
one dimension -- as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.

     We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values.

A Trusted Resource  As you face some of the most important, lasting decisions
you and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices -- choices that affect not only your loved ones today, but those your
legacy will touch in the future.

     Your financial advisor can provide sound financial insight, an integrated
approach to your investments and can serve as a knowledgeable friend with your
family's best interests at heart.

     In addition, we believe the potential presence of inflation and price

NUVEEN INTERMEDIATE DURATION MUNICIPAL BOND FUND
NUVEEN INSURED MUNICIPAL BOND FUND

From the Portfolio Managers' Perspective

A rising interest rate backdrop muted municipal bond returns during the 12
months ended April 30, 2000. Tom Spalding, portfolio manager of Nuveen
Intermediate Duration Municipal Bond Fund and Steve Krupa, portfolio manager of
Nuveen Insured Municipal Bond Fund, discuss the economic environment in which
the funds participated, as well as their funds' performance and key investment
strategies.

Q  What factors determined the municipal bond market's performance during the
12-month fiscal period ended April 30, 2000?

Tom  Persistent inflation worries and rising interest rates put pressure on
nearly all bonds, including municipal securities. The Federal Reserve Board
(the Fed) raised short-term interest rates five times over the past year by a
total of 125 basis points (1.25 percentage points) in an attempt to curb
economic growth and stifle inflationary pressures. Bond yields moved higher in
response to climbing rates, and bond prices -- which move opposite their yields
-- generally declined. (The Fed raised short-term interest rates a sixth time
after the fund's fiscal year ended -- bringing the short-term interest rate to
6.50%.)

Steve  Rising interest rates had a mixed effect on municipal bond supply and
demand, which also was a key determinant in municipal bond performance. Supply
dwindled as fewer municipal issuers found it economically advantageous to
refinance older debt as interest rates rose.

     In addition, many municipal issuers enjoyed budget surpluses thanks to the
overall strength of national, regional and local economies. As a result of their
diminished need for financing, many issuers cut back on issuing new debt.

     Demand, unfortunately, remained rather spotty throughout the year.
Initially, investors gravitated to the red-hot stock market, generally avoiding
fixed income securities in the process.

     When the stock market cooled in the early months of 2000 and municipal bond
yields rose to 6%, demand for municipals was stronger. The municipal bond
market performed better in the first quarter due to increased demand from
individual investors who wished to balance their portfolios with more fixed
income investments.

Q  How did Nuveen Intermediate Duration Municipal Bond Fund perform?

TOM  For the 12-month period ended April 30, 2000, the total return for Class A
shares at net asset value was -2.02%. The fund outperformed the Lipper General
Municipal Debt category, which returned -3.31%, but underperformed the Lehman
Brothers Municipal Bond Index, which returned 0.92%.*
     Shareholders in the 31% federal income tax bracket would have had to earn a
total return of 0.14% on a taxable investment to have earned the equivalent of
their fund's tax-exempt total return for the one-year period.
     As of April 30, 2000, the fund's SEC 30-day yield was 4.91%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 7.12% on
a taxable investment.

Q  What key strategies did you and your team use in managing the fund during the
year?

TOM  Maintaining a competitive distribution yield was a key focus for us. In an
effort to achieve that goal, we remained fully invested in intermediate- and
long-term bonds. They generally offered higher yields than shorter-term
securities and helped the fund optimize its tax-exempt dividend.
      Rising market interest rates and bond yields also presented us with some
attractive opportunities to trade older, lower-coupon bonds for current, high-
coupon bonds. A good example of this type of opportunity occurred when we sold
some bonds issued by New York City and replaced them with bonds issued by
Illinois Health.
      In making those and other trades, we looked for opportunities to improve
the fund's call protection. That provides a measure of protection against
having to surrender a high-yielding bond to the issuer before maturity.
      We also continued to focus on higher quality bonds, holding roughly 79% of
the portfolio in AAA/U.S. guaranteed or AA-rated bonds.

Q  Which bonds performed well during the past year? Which holdings were
disappointments?

Tom  Bonds that were refunded or bought back by their issuers performed
particularly well. Recently, for example, we sold back our holdings in bonds
issued by the Intermountain Power Agency at a significant premium over market
prices. We invested the proceeds from the sale into bonds that had lower
duration--or reduced interest-rate sensitivity--and had yields that were
higher than those sold.

     Healthcare bonds, on the other hand, were disappointing throughout most of
the past 12 months. Reduced Medicare payments and heightened competition
weighed heavily on hospitals and other healthcare facilities. We take a very
selective approach, concentrating on those hospitals that we believe can thrive
in response to increased competition.


Q  Turning to you, Steve, how did Nuveen Insured Municipal Bond Fund perform
during this fiscal period?

STEVE  For the 12-month period ended April 30, 2000, the total return for Class
A shares at net asset value was -2.19%. The fund outperformed the Lipper
General Municipal Debt category, which returned -3.12%, but underperformed the
Lehman Brothers Insured Municipal Bond Index, which returned -1.65%.**
     Shareholders in the 31% federal income tax bracket would have had to earn
a total return of 0.04% on a taxable investment to have earned the equivalent
of their fund's tax-exempt total return for the 12-month period.
     As of April 30, 2000, the fund's SEC 30-day yield was 4.74%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 6.87% on
a taxable investment.

Q  To what do you attribute the fund's performance and what were your key
strategies?

STEVE  Through our active management discipline, we took advantage of
opportunities that rising interest rates and higher bond yields afforded us. For
example, we added value by executing tax loss swaps, selling bonds at a loss in
order to buy higher-yielding bonds. As rates rose, prices on some of the fund's
holdings fell. When we sold several of the fund's holdings, tax losses were
incurred.
     These tax loss trades had two benefits for the fund. First, the
realized tax loss can be used to offset realized capital gains for up to eight
years. Furthermore, they helped increase tax-exempt income to the fund. In one
such swap in the first quarter of 2000, we sold New York City Water bonds and
captured a tax loss and then bought New York City Urban Development Corporation
bonds, which provided additional tax-free income.

<PAGE>

Q  Where else did you find value?

STEVE  We found particular value in the insured specialty sector. A specialty
state is a state with high state income taxes, such as California and New York.
Normally, municipal bonds issued in these states are more expensive than the
national norm (and, therefore, offer lower yields) because of the increased
demand for these bonds from income-tax payers in that state.
     In the final three months of 1999, however, new issue supply was large and
issuers in several specialty states had to offer their bonds at yields
comparable to national municipal bonds. We took advantage of this unusual market
dynamic to purchase several specialty state bonds for the fund.
     As supply abated in the first quarter of 2000 and the availability of bonds
became more limited, specialty state bonds generally performed well.

Q  What is your outlook for the coming months?

STEVE  From a historical perspective, municipals are priced attractively
relative to their Treasury counterparts. (Of course, Treasuries are backed by
the full faith and credit of the U.S. government.) To the extent that investors
seek out value in the bond market, municipals could benefit.

TOM  In addition to Federal Reserve policy, the near term outlook for municipals
will be influenced by the level of new issuance in the market. Our view is that
the municipal market could continue to be bolstered by diminished supply, as
long as demand remains constant or improves.

+ Class R shares returns are actual. Class A, B and C share returns are actual
for the period since class inception; returns prior to class inception are Class
R share returns adjusted for differences in sales charges and expenses, which
are primarily differences in distribution and service fees. Class A shares have
a 4.2% maximum sales charge. Class B shares have a CDSC that begins at 5% for
redemptions during the first year after purchase and declines periodically to 0%
over the following five years. Class B shares automatically convert to Class A

/[_]/The Index Comparison shows the change in value of a $10,000 investment in
the Class A shares of the Nuveen fund compared with the Lehman Brothers
Municipal Bond Index. The Lehman Municipal Bond Index is comprised of a broad
range of investment-grade municipal bonds, and does not reflect any initial or
ongoing expenses. The Nuveen fund return depicted in the chart reflects the
initial maximum sales charge applicable to A shares (4.20%) and all ongoing fund
expenses. For periods prior to inception of Class A shares, performance reflects
Class R share performance adjusted for differences in expenses, which are
primarily differences in distribution and service fees.

Returns are historical and do not guarantee future performance. Investment
returns and principal value will fluctuate so that when shares are redeemed,
they may be worth more or less than their original cost. Performance of classes
will differ. For additional information, please see the fund prospectus.

 Terms To Know
--------------------------------------------------------------------------------

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond A bond issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a tax-exempt investment.

+Class R shares returns are actual. Class A, B and C share returns are actual
for the period since class inception; returns prior to class inception are
Class R share returns adjusted for differences in sales charges and expenses,
which are primarily differences in distribution and service fees. Class A shares
have a 4.2% maximum sales charge. Class B shares have a CDSC that begins at 5%
for redemptions during the first year after purchase and declines periodically
to 0% over the following five years. Class B shares automatically convert to
Class A shares eight years after purchase. Class C shares have a 1% CDSC for
redemptions within one year, which is not reflected in the one-year total
return.

/[_]/The Index Comparison shows the change in value of a $10,000 investment in
the Class A shares of the Nuveen fund compared with the Lehman Brothers
Municipal Bond Index. The Lehman Municipal Bond Index is comprised of a broad
range of investment-grade municipal bonds, and does not reflect any initial or
ongoing expenses. The Nuveen fund return depicted in the chart reflects the
initial maximum sales charge applicable to A shares (4.20%) and all ongoing
fund expenses. For periods prior to inception of Class A shares, performance
reflects Class R share performance adjusted for differences in expenses, which
are primarily differences in distribution and service fees.

Returns are historical and do not guarantee future performance. Investment
returns and principal value will fluctuate so that when shares are redeemed,
they may be worth more or less than their original cost. Performance of classes
will differ. For additional information, please see the fund prospectus.

--------------------------------------------------------------------------------
 Terms To Know
--------------------------------------------------------------------------------

The following are a few terms used throughout this report.

Duration  A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Federal Fund Rates  The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond  A bond issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield  A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield  The return an investor would have to realize on a
fully taxable investment to equal the stated yield on a tax-exempt investment.

Notes to Financial Statements


1. General Information and Significant Accounting Policies

The Nuveen Flagship Municipal Trust (the "Trust") is an open-end diversified
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Intermediate Duration Municipal Bond
Fund ("Intermediate Duration Municipal Bond") and the Nuveen Insured Municipal
Bond Fund ("Insured Municipal Bond") (collectively, the "Funds"), among others.
The Trust was organized as a Massachusetts business trust on July 1, 1996.

Each fund seeks to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

Effective November 24, 1999, Nuveen Municipal Bond Fund ("Municipal Bond")
changed its name to Nuveen Intermediate Duration Municipal Bond Fund. Also
effective November 24, 1999, the fund will invest in a diversified portfolio of
investment grade quality bonds of various maturities with a weighted average
duration of between three and 10 years. Both changes were approved by the Board
of Trustees of Municipal Bond on November 4, 1999.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Funds' Board of Trustees. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
April 30, 2000, Intermediate Duration Municipal Bond and Insured Municipal Bond
had outstanding when-issued purchase commitments of $8,585,983 and $15,851,324,
respectively.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared monthly as a dividend and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount realized from investment transactions. The
Funds currently consider significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, each Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal income tax, to retain such tax-exempt
status when distributed to the shareholders of the Funds. All monthly tax-exempt
income dividends paid during the fiscal year ended April 30, 2000, have been
designated Exempt Interest Dividends. Net realized capital gain and market
discount distributions are subject to federal taxation.

Insurance

Insured Municipal Bond invests in municipal securities which are either covered
by insurance or backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Fund's shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Fund ultimately disposes of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Fund. Accordingly, neither the prices used in determining the market value
of the underlying municipal securities nor the net asset value of the Fund's
shares include value, if any, attributable to the Portfolio Insurance. Each
policy of the Portfolio Insurance does, however, give the Fund the right to
obtain permanent insurance with respect to the municipal security covered by the
Portfolio Insurance policy at the time of its sale.

Flexible Sales Charge Program

Each Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available only under limited circumstances, or by specified classes
of investors.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Funds are authorized to invest in
such financial instruments, and may do so in the future, they did not make any
such investments during the fiscal year ended April 30, 2000.

Expense Allocation

Expenses of each Fund that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby the custodian fees
and expenses are reduced by credits earned on each Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

6. Management Fee and Other Transactions with Affiliates

Under the Trust's investment management agreement with Nuveen Advisory Corp.
(the "Adviser"), a wholly owned subsidiary of The John Nuveen Company, each
Fund pays an annual management fee, payable monthly, at the rates set forth
below which are based upon the average daily net assets of each Fund as
follows:

<TABLE>
<CAPTION>

Average Daily Net Assets                Management Fee
---------------------------------------------------------
<S>                                     <C>
For the first $125 million                  .5000 of 1%
For the next $125 million                   .4875 of 1
For the next $250 million                   .4750 of 1
For the next $500 million                   .4625 of 1
For the next $1 billion                     .4500 of 1
For net assets over $2 billion              .4250 of 1
=========================================================
</TABLE>

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Trust pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its officers, all of whom receive remuneration for their services
to the Trust from the Adviser or its affiliates.

The Adviser has agreed to waive part of its management fees or reimburse certain
expenses of each Fund in order to limit total expenses to .75 of 1% of the
average daily net asset value of Intermediate Duration Municipal Bond and .975
of 1% of the average daily net asset value of Insured Municipal Bond, excluding
any 12b-1 fees applicable to Class A, B and C Shares. The Adviser may also
voluntarily agree to reimburse additional expenses from time to time, which may
be terminated at any time at its discretion.

During the fiscal year ended April 30, 2000, John Nuveen & Co Incorporated (the
"Distributor"), a wholly-owned subsidiary of The John Nuveen Company, collected
sales charges on purchases of Class A Shares of approximately $278,100 and
$229,000 for Intermediate Duration Municipal Bond and Insured Municipal Bond,
respectively, of which approximately $259,600 and $229,000, respectively, were
paid out as concessions to authorized dealers. The Distributor also received
12b-1 service fees on Class A Shares, substantially all of which were paid to
compensate authorized dealers for providing services to shareholders relating to
their investments.

During the fiscal year ended April 30, 2000, the Distributor compensated
authorized dealers directly with approximately $215,300 and $359,600 in
commission advances at the time of purchase for Intermediate Duration Municipal
Bond and Insured Municipal Bond, respectively. To compensate for commissions
advanced to authorized dealers, all 12b-1 service fees collected on Class B
Shares during the first year following a purchase, all 12b-1 distribution fees
collected on Class B Shares, and all 12b-1 service and distribution fees
collected on Class C Shares during the first year following a purchase are
retained by the Distributor. During the fiscal year ended April 30, 2000, the
Distributor retained approximately $118,300 and $154,800 in such 12b-1 fees for
Intermediate Duration Municipal Bond and Insured Municipal Bond, respectively.
The remaining 12b-1 fees charged to the Funds were paid to compensate authorized
dealers for providing services to shareholders relating to their investments.
The Distributor also retained approximately $94,500 and $105,400 of CDSC on
share redemptions for Intermediate Duration Municipal Bond and Insured Municipal
Bond, respectively, during the fiscal year ended April 30, 2000.

7. Composition of Net Assets

</TABLE>

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. Government or U.S. Government agency
securities, either of which ensure the timely payment of principal and interest
in the event of default (37% for Intermediate Duration Municipal Bond and 100%
for Insured Municipal Bond). Such insurance or escrow, however, does not
guarantee the market value of the municipal securities or the value of the
Funds' shares.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Flagship Municipal Trust:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of the Nuveen Intermediate Duration Municipal Bond
Fund and Nuveen Insured Municipal Bond Fund (two of the portfolios constituting
the Nuveen Flagship Municipal Trust (a Massachusetts business trust)), as of
April 30, 2000, and the related statements of operations, statements of changes
in net assets and the financial highlights for the periods indicated thereon.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of April 30, 2000, by correspondence with the custodian and brokers. As
to securities purchased but not received, we requested confirmation from brokers
and, when replies were not received, we carried out alternative auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Intermediate Duration Municipal Bond Fund and Nuveen Insured Municipal Bond Fund
of the Nuveen Flagship Municipal Trust as of April 30, 2000, and the results of
their operations, the changes in their net assets and their financial highlights
for the periods indicated thereon in conformity with accounting principles
generally accepted in the United States.

DEAR

Shareholder,

As personal wealth continues to grow at an ever-increasing rate, people are
realizing the power of their investments to do good and to make a difference in
their families and communities now and for generations to come.

Setting financial goals is an important first step toward building wealth. At
Nuveen Investments, we believe those goals should not be considered ends in
themselves. Rather, you and your financial advisor's focus should be on
realizing your life's dreams -- the things that matter most to you and how you
can make them happen -- or make them better.

Through a well-crafted financial plan, you have the chance to shape future
generations -- to broaden your sphere of influence -- to leave your legacy.

As you develop that plan, you'll want to consider the different ways your
success can benefit others. You may find that you want to create a new set of
goals to achieve this. Working with your financial advisor, you have the ability
to make those dreams a reality -- for yourself and future generations.

Family Wealth Management Too often, family wealth management is thought of in
one dimension -- as the stewardship of your household's financial resources. At
Nuveen Investments, we think of family wealth management as the map to help you
reach your financial, and your life's, destinations. It's a multi-faceted
strategy to plan for not just your needs, but the needs of future generations.
     We are dedicated to helping you and your financial advisor develop a family
wealth management strategy unique to you and your goals and values.

A Trusted Resource  As you face some of the most important, lasting decisions
you and your family will make, you'll want to draw upon the support, counsel and
objectivity of a trusted advisor. That's because your financial advisor has the
expertise and access to other professionals who can help you make informed
choices -- choices that affect not only your loved ones today, but those your
legacy will touch in the future.

     Your financial advisor can provide sound financial insight, an integrated
approach to your investments and can serve as a knowledgeable friend with your
family's best interests at heart.

                                                            ANNUAL REPORT page 1
<PAGE>

     In addition, we believe the potential presence of inflation and price
swings in the markets reinforce the importance of working with an advisor,
staying focused on the long term and adhering to your financial plan.  With a
sound plan in place, you may be better positioned to weather the markets' ups
and downs.

     In fact, you may be reading this report at the suggestion of your financial
advisor. We've prepared the following interview to let you know what the
investment and research management teams have done during your fund's fiscal
period.

     For more information on any Nuveen investment, including a prospectus,
contact your financial advisor. Or call Nuveen at (800) 621-7227 or visit our
Internet site at www.nuveen.com. Please read the prospectus carefully before you
invest or send money.

     Since 1898, Nuveen has been synonymous with investments that stand the test
of time. We are committed to maintaining that reputation and working with
financial advisors to provide investment solutions that help individuals achieve
their lives dreams. Thank you for your continued confidence.

Sincerely,

Tim Schwertfeger

NUVEEN FLAGSHIP FLORIDA MUNICIPAL BOND FUND

From the Portfolio Managers' Perspective
--------------------------------------------------------------------------------

For nearly a year, the Federal Reserve Board (the Fed) has continued on a track
to raise interest rates in an attempt to stymie inflation. These "tightening"
measures put pressure on nearly all bonds, including municipal securities. Rick
Huber, portfolio manager of the Nuveen Flagship All-American Municipal Bond Fund
and Nuveen Flagship Limited Term Municipal Bond Fund, and Paul Brennan,
portfolio manager of Nuveen Flagship Intermediate Municipal Bond Fund, discuss
the economic environment in which the funds participated, as well as their
funds' performance and key investment strategies

+ The Morningstar ratings are overall for the municipal bond category and relate
to Class A shares only; the other classes may vary. Morningstar proprietary
ratings reflect historical risk-adjusted performance as of 4/30/00 and are
subject to change every month. Past performance is no guarantee of future
results. Ratings are calculated from the funds' three-, five-, and 10-year
average annual returns (if applicable) in excess of 90-day Treasury bill
returns, with appropriate fee adjustments, and a risk factor that reflects fund
performance below 90-day T-bill returns.

Nuveen Flagship All-American Municipal Bond Fund received 3 stars for the 3-and
5-year periods and 4 stars for the 10-year period.

The Nuveen Intermediate Fund received 3 stars for the 3-year period and 4 stars
for the 5-year period.

The Nuveen Flagship Limited Term Fund received 4 stars for the 3- and 5-year
periods and 5 stars for the 10-year period.

The top 10% of the funds in a broad asset class receive five stars, and the next
22.5% receive four stars, and the next 35% receive three stars. The funds were
rated among 1,692 funds for the three-year period, 1,438 for the five-year
period and 405 for the 10-year period.

Performance figures are quoted for Class A shares at net asset value. Comments
cover the fiscal 12-month period ended April 30, 2000. The views expressed
reflect those of the portfolio management team and are subject to change at any
time, based on market and other conditions.

A voluntary expense limitation was in place for Nuveen Intermediate Municipal
Bond Fund during the period. Total return would have been less.


Q    How would you describe the overall fixed-income investing environment
during the past 12 months?

Rick Rising interest rates translated into a difficult bond market environment.
The Fed raised interest rates five times during the past 12 months, lifting the
federal funds rates -- the rate banks charge each other for overnight loans --to
6%, a five-year high. After the fund's fiscal annual period ended, a sixth hike
followed on May 16, bringing the fed funds rate to 6.50%.

     These moves were intended to curb the strong U.S. economy and stifle any
inflationary pressures that might be brewing as a result. Bond yields rose in
response, and their prices -- which generally move in the opposite direction of
their yields -- posted losses.

PAUL Supply and demand also played a role in determining municipal bond returns
during the past 12 months.

     On a positive note, the supply of municipal bonds dwindled as rising rates
extinguished opportunities for issuers to refinance or refund older, more
expensive debt. In addition, the strength of national and local economies
translated into higher revenues and tax collections for many municipalities,
thereby reducing their debt financing needs. These developments translated into
a 40% reduction of the supply of municipals in the first quarter of 2000,
compared to the same quarter a year earlier.

     Demand, on the other hand, was spotty. Lured by the red-hot returns of
technology and other stocks, investors generally avoided fixed-income
investments throughout most of 1999. In early 2000, however, the demand for
municipals became strong again when technology stocks experienced a downturn and
municipal bond yields touched 6%.

subject to change.

     1  The Lipper Peer Group returns represent the total return of the 274
        funds in the Lipper General Municipal Debt Funds category for the period
        from May 1, 1999, through April 30, 2000. The returns assume
        reinvestment of dividends and do not reflect any applicable sales
        charges.

     2  The Lehman Brothers Municipal Bond Indices are comprised of a broad
        range of investment-grade municipal bonds and do not reflect any initial
        or ongoing expenses.

     3  Taxable equivalent yield/total return represents the yield/total return
        on a taxable investment necessary to equal the yield/total return of the
        Nuveen Fund on an after-tax basis. The taxable-equivalent yield shown is
        based on the 30-day SEC yield and a federal income tax rate of 31%. The
        taxable equivalent total return is based on the fund's one-year total
        return and the 31% federal income tax rate.

     4  The Lipper Peer Group returns represent the return of the 41 funds in
        the Short-Intermediate Municipal Debt Funds category for the period from
        May 1, 1999, through April 30, 2000. The returns assume reinvestment of
        dividends and do not reflect any applicable sales charges.


Q How did Nuveen Flagship All-American Municipal Bond Fund perform during the
period?

RICK For the 12-month period ended April 30, 2000, the fund reported a total
return of -4.48% for Class A shares on net asset value. In comparison, the
Lipper General Municipal Bond Peer Group reported a total return of -3.31% for
the same one-year period, and the Lehman Brothers Municipal Bond Index reported
a return of -0.92%./1/, /2/ Shareholders in the 31% federal income tax bracket
would have to earn a total return of -2.21% on a taxable investment to have
earned the equivalent of their fund's tax-exempt total return for the one-year
period./3/

     As of April 30, 2000, the fund's SEC 30-day yield was 5.41%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 7.84% on
a taxable investment./3/

Q How did Nuveen Flagship Limited Term Municipal Bond Fund perform during its
fiscal period?

RICK For the 12-month period ended April 30, 2000, the total return for Class A
shares on net asset value was -0.57%. In comparison, the Lipper Short-
Intermediate Municipal Debt Fund Peer Group returned 0.16% and the Lehman
Brothers Municipal Bond Index (5-year) reported a return of 0.36%./2/, /4/
Shareholders in the 31% federal income tax bracket would have to earn a total
return of 1.43% on a taxable investment to have earned the equivalent of their
fund's tax-exempt total return for the one-year period./3/

     As of April 30, 2000, the fund's SEC 30-day yield was 4.64%. For investors
in the federal income tax bracket, that is equivalent to a yield of 6.72% on a
taxable investment./3/

Q What investment strategies did you employ during the past year?

RICK To maintain a competitive distribution yield, each fund had significant
holdings in BBB-rated and non-rated securities, which generally lagged their
higher-quality counterparts during the past year. As interest rates rose,
investors' aversion to risk seemingly intensified, and lower-quality and non-
rated municipal bonds fell out of favor. This occurred despite the fact that the
strong U.S. economy meant improving credit fundamentals for many issuers of BBB-
rated and non-rated bonds.

     In response to investors' ongoing avoidance of lower-quality bonds, we
reduced our stake in them over the past six months. That said, we continue to
hold some selected BBB-rated and non-rated hospital, industrial development and
utility bonds because they offered attractive yields and the potential to
outpace higher-rated securities if they move back into favor.

Q Where did you find attractive opportunities during the period?

RICK We capitalized on the recent rise in interest rates and the resulting
decline in bond prices to improve All-American's tax efficiency. As rates rose,
prices on some of the fund's holdings fell. By selling certain bonds at a loss,
we created tax-loss carryforwards that can be used to offset current and/or
future realized capital gains. An additional benefit of these transactions is
that we used the proceeds from the sale of bonds to finance purchases of new
bonds with higher income streams.

ANNUAL REPORT page 4
<PAGE>

Q Paul, what can you tell us about Nuveen Flagship Intermediate Municipal Bond
Fund's performance?

PAUL The fund reported a total return of -2.17% for the 12-month period ended
April 30, 2000 for Class A shares on net asset value. In comparison, the Lipper
National Intermediate Municipal Fund category reported a -1.17% total return for
the 12-month period and the Lehman Brothers Municipal Bond Index (7-year)
returned -0.03%./2/,/5/ Shareholders in the 31% federal income tax bracket would
have had to earn a total return of -0.08% on a taxable investment to have earned
the equivalent of their fund's tax-exempt total return for the 12-month
period./3/

     As of April 30, 2000, the fund's SEC 30-day yield was 4.97%. For investors
in the 31% federal income tax bracket, that is equivalent to a yield of 7.20% on
a taxable investment./3/

     The fund's lag stemmed mostly from our focus on maximizing distribution
yield by maintaining a somewhat longer duration than our peers. Duration is a
measure of a bond's interest rate sensitivity; the longer a bond's duration, the
more its share price will fall when rates rise and vice versa. Among
intermediate maturity bonds, an investor typically can pick up a fair amount of
additional yield for moving out each successive year of maturity. With interest
rates on the rise as they were during the fiscal period, however, the fund's
longer duration detracted from performance.

Q What were some of your other key strategies?

PAUL Like Nuveen Flagship All-American and Nuveen Flagship Limited Term
Municipal Bond Fund, we identified several opportunities to do some tax loss
swapping. When we made those trades, we looked to improve the fund's overall
call protection, which can help insulate the fund from the inopportune
redemption of bonds that can occur when interest rates fall.

     Recently, for example, we purchased bonds issued by the City of Chicago,
the District of Columbia and Boone McHenry Dekalb School District, all of which
carried call protection in excess of 10 years.

     We also maintained a significant position in non-rated bonds and those
rated BBB, which is at the lower end of the investment grade credit rating
scale, as judged by Standard & Poor's and Moody's Investors Service.

     As Rick explained, a lack of demand caused these bonds to underperform
their higher-quality counterparts over the past year. But we think that the pain
they suffered in response was overdone, and that selected non- and BBB-rated
securities offer the potential to outperform. Furthermore, they offer a very
attractive yield advantage over higher-rated securities, although they do carry
more risk.

Q  What's ahead for the municipal market and these three Nuveen Flagship
municipal bond funds?

RICK  At the end of the period, bond prices seemingly reflected investors'
expectations for further interest rate hikes. Aside from interest rates, supply
and demand conditions will also play a role in the performance of municipal
bonds. We expect supply to remain low, a consequence of higher interest rates.
Demand is more of an unknown. As we mentioned in the beginning, investors
generally avoided fixed-income investments of all types during 1999 in favor of
stocks. If the trend we've seen in early 2000 continues and investors continue
to seek out more fixed-income investments, municipals could benefit.

   investment-grade municipal bonds and do not reflect any initial or ongoing
   expenses.

   taxable investment necessary to equal the yield of the Nuveen Fund on an
   after-tax basis. The taxable-equivalent yield shown is based on the 30-day
   SEC yield and a federal income tax rate of 31%. The taxable equivalent total
   return is based on the fund's one-year total return and the 31% federal tax
   rate.

   the Lipper Intermediate Municipal Debt Funds category for the period from May
   1, 1999, through April 30, 2000. The returns assume reinvestment of dividends
   and do not reflect any applicable sales charges.

 . The Index Comparison shows the change in value of a $10,000 investment in the
  Class A shares of the Nuveen fund compared with the Lehman Brothers Municipal
  Bond Index. The Lehman Municipal Bond Index is comprised of a broad range of
  investment-grade municipal bonds, and does not reflect any initial or ongoing
  expenses. The Nuveen fund return depicted in the chart reflects the initial
  maximum sales charge applicable to A shares (4.20%) and all ongoing fund
  expenses.

Returns are historical and do not guarantee future performance. Investment
returns and principal value will fluctuate so that when shares are redeemed,
they may be worth more or less than their original cost. Performance of classes
will differ. For additional information, please see the fund prospectus.

Terms To Know

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Fed Tightening When the Federal Reserve is following tight money policy, it is
essentially decreasing the money supply by increasing the fed funds rate and
making money more expensive to borrow. The intention is to slow the growth of
the economy and curtail inflation.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond A debt issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a
tax-exempt investment.

 Terms To Know

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Fed Tightening When the Federal Reserve is following tight money policy, it is
essentially decreasing the money supply by increasing the fed funds rate and
making money more expensive to borrow. The intention is to slow the growth of
the economy and curtail inflation.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond A debt issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a tax-exempt investment.

NUVEEN HIGH YIELD MUNICIPAL BOND FUND

From the Portfolio Manager's Perspective
------------------------------------------------------------------------------

1 The Lipper Peer Group returns represent the total return of the 57 funds in
  the Lipper High Yield Municipal Debt Funds category for the period from June
  30, 1999, through April 30, 2000 and the 59 funds in the Lipper category for
  the year-to-date period ending April 30, 2000. The Lipper return is compared
  to Nuveen High Yield Municipal Bond Fund's performance since its inception
  June 7, 1999. The fund's return from June 30, 1999 to April 30, 2000, was
  0.16%. The returns assume reinvestment of dividends and do not reflect any
  applicable sales charges.

Investment by the fund in lower-rated and nonrated securities presents greater
risk of loss of principal than investments in investment-grade securities.

Performance figures are quoted for Class A shares at net asset value. Comments
cover the period from the fund's inception on June 7, 1999, through its fiscal
year end, April 30, 2000. The views expressed reflect those of the portfolio
management team and are subject to change at any time, based on market and other
conditions.

A voluntary expense limitation was in place for Nuveen High Yield Municipal Bond
Fund during the period.

Nuveen High Yield Municipal Bond Fund features portfolio management by Nuveen
Investment Management, a team of portfolio managers and research analysts
committed to a disciplined, research-oriented investment strategy. To help you
understand the fund's performance during its fiscal year ending April 30, 2000,
we spoke with Steve Peterson, lead portfolio manager of the fund.

Q The Nuveen High Yield Municipal Bond Fund began operations on June 7, 1999.
-
The fund reported a total return of -2.69% from its inception through April 30,
2000. Although not posting a positive return, the fund did outperform the Lipper
High Yield Municipal Debt Fund category average of -3.03.1 It looks like high
yield municipal bond funds in general had a tough time. What happened in this
market over the period?

STEVE The municipal bond market had a very challenging year in 1999. New
-----
issuance was stagnant, and demand was flat. The stock market frenzy throughout
1999 kept investors' attention, not the fixed income market. The residual
effects of that frenzy seemed to keep investors coming back for more, even amid
the unprecedented amount of volatility in the Dow Jones Industrial Average and
the Nasdaq Composite Index during the first four months of 2000.

       Although stocks took a beating, we still didn't see the "flight-to-
quality" into bonds that we usually expect when the stock market goes sour.
There was a definite lack of interest in the bond market -- and high yield
municipals in particular -- throughout the period. But that wasn't a bad thing
at all, in our opinion. In fact, we were able to take advantage of a market full
of opportunities to find attractive value and yields and even increase the
fund's dividend rate.

Q For this fund, you look for municipal bonds that are undervalued and
-
therefore selling at attractive prices or yields. So during this period, you
really saw the out-of-favor high yield municipal market as full of potential?

STEVE Yes. The entire high yield municipal market was out of favor, with both
-----
issuance and demand down, but we still found very viable bond issues for the
fund. Our overreaching goal in any environment is to find bonds that we believe
are mispriced, that through our research we determine offer strong potential.

Q Do you have any specific examples?
-

STEVE Ohio Bayshore is a great example. It's a small independent power plant
-----
under construction that, when completed, should provide some of the lowest cost
power in Ohio, a state that generally has had very high-cost energy. The project
was behind schedule, which was why this issue was out of favor. But the reason
for the delay was simply that the tight labor market made welders and
construction workers who were available to work hard to come by. That, in our
opinion, was the temporary result of a

 ANNUAL REPORT page 10
<PAGE>

strong economy, not a reflection of poor management. These bonds were issued
with attractive yields at 7.75% to 8%.

     We also continued to find potential in the embattled healthcare sector,
still under pressure from cuts in federal Medicare and Medicaid reimbursement,
aggressive HMO pricing and the move from inpatient to outpatient care. But even
in these conditions, we feel healthcare is something people will always need,
and those organizations that have positioned themselves favorably can offer very
attractive bond issues while remaining competitive.

     One such example is Kentucky Appalachian Regional Healthcare. This issue
was backed by six Kentucky and Virginia hospitals and offered a yield of nearly
9.5%. Keep in mind that's a tax-free yield; the equivalent yield on a similar
taxable bond would be close to 16%. We believe this security offered exceptional
value since these hospitals offer essential services and are insulated from
competition due to their rural location -- the nearest competing hospital is
more than an hour-and-a-half away. Their overall debt level was also very
moderate, which impressed us.

     It was impressive yields such as these that allowed us to increase the
dividend during the fiscal period.


Q Typically, a rising interest rate environment is not a very favorable one for
-
bonds, yet if we look at the year-to-date period as of April 30, 2000 -- a
period in which the Federal Reserve (the Fed) raised rates twice -- the fund
returned 2.01%, versus the Lipper category average for the same period of
0.64%.1 The fund's tax-free return even outpaced the stock market -- negative
0.04% measured by the S&P 500 Index.2 How do you explain this?

STEVE The stock market tends to operate on a different level than that of the
-----
bond market. Particularly during the first part of 2000, investors seemed to
take it to an entirely different plane. It seemed to be based on random guesses
on where prices would go, with little regard for fundamentals like profits and
cash flows. Bonds, on the other hand, are priced according to factors like
interest rates and credit quality of issuers.

     The high yield municipal bond market itself began a rebound after a rocky
1999. The very structure of high yield municipal bonds makes them less sensitive
to changing interest rates. Their sensitivity lies more in the credit quality of
the issuer, otherwise known as credit risk.  While higher credit risk is
inherent in a high yield fund, we work to mitigate credit risk for the fund
through thorough analysis and sometimes even by negotiating structure directly
with the issuer.

     Since no one but Chairman Alan Greenspan's Fed has any control over
interest rates, we tried to minimize the fund's exposure to interest rate risk
wherever possible. We consciously sought out bonds that offered shorter
maturities to help decrease the fund's duration, which is a measure of how
sensitive the fund is to interest rate risk. A shorter duration means less
interest rate sensitivity -- important in this environment.

Another factor in this market was the yield differential between lower-rated
bonds, such as those the fund invests in, and higher-rated bonds. The wider this
differential -- or "spread" -- the more affordable high yield municipals are,
and therefore the more the potential for gains, even factoring in the higher
risk potential.

For example, one bond we bought recently paid a yield premium of 375 basis
points -- or nearly four percentage points -- over an otherwise similar higher-
rated bond. One year ago we were seeing spreads of only 100 to 125 basis points,
or around one percent difference in yields.

Q What is your outlook for the near future in the high yield municipal bond
-
market?

STEVE Throughout the coming months, we plan to maintain the fund's duration at
-----
or near its current low level to help keep its sensitivity to interest rates
down.

      However, we are optimistic that future Fed interest rate increases will be
relatively modest. It is our experience that Fed rate increases take about 12 to
18 months to have their intended effect on the economy, so the impact should
begin to emerge soon.

 Terms To Know

The following are a few terms used throughout this report.

Duration A mathematical measure of the price sensitivity of a bond fund's
portfolio to changes in interest rates. Duration is stated in years; typically
the shorter the duration, the less price and return variability you can expect
in the fund's price per share as interest rates change.

Federal Fund Rates The interest rate charged by banks to lend to other banks
needing overnight loans; this figure is the most sensitive indicator of the
direction of interest rates.

Municipal Bond An IOU issued by a state, city, or other municipality to finance
public works such as the construction of roads or schools. The interest is
usually free from federal income tax and may be free from state and local taxes
as well.

SEC Yield A standardized measure of the current net market yields on a mutual
fund's investment portfolio.

Taxable Equivalent Yield The return an investor would have to realize on a fully
taxable investment to equal the stated yield on a tax-exempt investment.

3 Taxable-equivalent yield/total return represents the yield/total return on a
taxable investment necessary to equal the yield/total return of the Nuveen fund
on an after-tax basis. The taxable equivalent yield shown is based on the 30-day
SEC yield and a federal income tax rate of 31%. The taxable equivalent total
return is based on the fund's one-year total return and the 31% federal tax
rate.

All-American, Intermediate and Limited Term seek to provide high tax-free income
and preservation of capital through investments in diversified portfolios of
quality municipal bonds.

High Yield invests substantially all of its assets in municipal bonds for high
current income exempt from regular federal income taxes and capital
appreciation. Under normal circumstances, at least 65% of the Fund's assets will
be invested in medium to low-quality municipal bonds and may also invest in
defaulted municipal bonds, inverse floating rate securities, municipal forwards
and short-term municipal investments.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
accounting principles generally accepted in the United States.

Securities Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Trustees. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
April 30, 2000, All-American had an outstanding when-issued purchase commitment
of $6,195,660. There were no such outstanding purchase commitments in any of the
other Funds.

Investment Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared monthly as a dividend and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Federal Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Funds
currently consider significant net realized capital gains and/or market discount
as amounts in excess of $.001 per share. Furthermore, each Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal income tax, to retain such tax-exempt status when
distributed to the shareholders of the Funds. All monthly tax-exempt income
dividends paid during the fiscal year ended April 30, 2000, have been designated
Exempt Interest Dividends. Net realized capital gain and market discount
distributions are subject to federal taxation.

Flexible Sales Charge Program

Each Fund offers Class A, C and R Shares. All-American and High Yield also offer
Class B Shares. Class A Shares are sold with a sales charge and incur an annual
12b-1 service fee. Class A Share purchases of $1 million or more are sold at net
asset value without an up-front sales charge but may be subject to a contingent
deferred sales charge ("CDSC") if redeemed within 18 months of purchase. Class B
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class B Shares agrees to pay a CDSC of up
to 5% depending upon the length of time the shares are held by the investor
(CDSC is reduced to 0% at the end of six years). Class B Shares convert to Class
A Shares eight years after purchase. Class C Shares are sold without a sales
charge but incur annual 12b-1 distribution and service fees. An investor
purchasing Class C Shares agrees to pay a CDSC of 1% if Class C Shares are
redeemed within one year of purchase. Class R Shares are not subject to any
sales charge or 12b-1 distribution or service fees. Class R Shares are available
only under limited circumstances, or by specified classes of investors.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Funds are authorized to invest in
such financial instruments, and may do so in the future, they did not make any
such investments during the fiscal year ended April 30, 2000.

Expense Allocation

Expenses of each Fund that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby the custodian fees
and expenses are reduced by credits earned on each Fund's cash on deposit with
the bank. Such deposit arrangements are an alternative to overnight investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period. Actual
results may differ from those estimates.

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. Government or U.S. Government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default (33% for All-American, 33% for Intermediate, 31% for
Limited Term and 5% for High Yield). Such insurance or escrow, however, does not
guarantee the market value of the municipal securities or the value of any of
the Funds' shares.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Flagship Municipal Trust:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of Nuveen Flagship All-American Municipal Bond Fund,
Nuveen Flagship Intermediate Municipal Bond Fund, Nuveen Flagship Limited Term
Municipal Bond Fund and Nuveen High Yield Municipal Bond Fund (collectively, the
"Funds") (four of the portfolios constituting the Nuveen Flagship Municipal
Trust (a Massachusetts business Trust)), as of April 30, 2000, and the related
statements of operations, statements of changes in net assets and the financial
highlights for the periods indicated thereon. These financial statements and
financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the Funds
for the years ended April 30, 1997 and prior were audited by other auditors
whose report dated June 13, 1997, expressed an unqualified opinion on those
financial highlights.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of April 30, 2000, by correspondence with the custodian and brokers. As
to securities purchased but not received, we requested confirmation from
brokers, and when replies were not received, we carried out alternative auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Flagship All-American Municipal Bond Fund, Nuveen Flagship Intermediate
Municipal Bond Fund, Nuveen Flagship Limited Term Municipal Bond Fund and Nuveen
High Yield Municipal Bond Fund of the Nuveen Flagship Municipal Trust as of
April 30, 2000, the results of their operations, the changes in their net
assets, and their financial highlights for the periods indicated thereon in
conformity with accounting principles generally accepted in the United States.

Item 24: Persons Controlled by or under Common Control with Registrant
Not applicable.

Item 25: Indemnification
Section 4 of Article XII of Registrant's Amended and Restated Declaration of
Trust provides as follows:

Subject to the exceptions and limitations contained in this Section 4, every
person who is, or has been, a Trustee, officer, employee or agent of the Trust,
including persons who serve at the request of the Trust as directors, trustees,
officers, employees or agents of another organization in which the Trust has an
interest as a shareholder, creditor or otherwise (hereinafter referred to as a
"Covered Person"), shall be indemnified by the Trust to the fullest extent
permitted by law against liability and against all expenses reasonably incurred
or paid by him in connection with any claim, action, suit or proceeding in
which he becomes involved as a party or otherwise by virtue of his being or
having been such a Trustee, director, officer, employee or agent and against
amounts paid or incurred by him in settlement thereof.

No indemnification shall be provided hereunder to a Covered Person:

  (a) against any liability to the Trust or its Shareholders by reason of a
  final adjudication by the court or other body before which the proceeding
  was brought that he engaged in willful misfeasance, bad faith, gross
  negligence or reckless disregard of the duties involved in the conduct of
  his office;

  (b) with respect to any matter as to which he shall have been finally
  adjudicated not to have acted in good faith in the reasonable belief that
  his action was in the best interests of the Trust; or

  (c) in the event of a settlement or other disposition not involving a final
  adjudication (as provided in paragraph (a) or (b)) and resulting in a
  payment by a Covered Person, unless there has been either a determination
  that such Covered Person did not engage in willful misfeasance, bad faith,
  gross negligence or reckless disregard of the duties involved in the
  conduct of his office by the court or other body approving the settlement
  or other disposition or a reasonable determination, based on a review of
  readily available facts (as opposed to a full trial-type inquiry), that he
  did not engage in such conduct:

    (i) by a vote of a majority of the Disinterested Trustees acting on the
    matter (provided that a majority of the Disinterested Trustees then in
    office act on the matter); or

    (ii) by written opinion of independent legal counsel.

The rights of indemnification herein provided may be insured against by
policies maintained by the Trust, shall be severable, shall not affect any
other rights to which any Covered Person may now or hereafter be entitled,
shall continue as to a person who has ceased to be such a Covered Person and
shall inure to the benefit of the heirs, executors and administrators of such a
person. Nothing contained herein shall affect any rights to indemnification to
which Trust personnel other than Covered Persons may be entitled by contract or
otherwise under law.

Expenses of preparation and presentation of a defense to any claim, action,
suit or proceeding subject to a claim for indemnification under this Section 4
shall be advanced by the Trust prior to final disposition thereof upon receipt
of an undertaking by or on behalf of the recipient to repay such amount if it
is ultimately determined that he is not entitled to indemnification under this
Section 4, provided that either:

  (a) such undertaking is secured by a surety bond or some other appropriate
  security or the Trust shall be insured against losses arising out of any
  such advances; or

                                      C-2
<PAGE>

  (b) a majority of the Disinterested Trustees acting on the matter (provided
  that a majority of the Disinterested Trustees then in office act on the
  matter) or independent legal counsel in a written opinion shall determine,
  based upon a review of the readily available facts (as opposed to a full
  trial-type inquiry), that there is reason to believe that the recipient
  ultimately will be found entitled to indemnification.

As used in this Section 4, a "Disinterested Trustee" is one (x) who is not an
Interested Person of the Trust (including, as such Disinterested Trustee,
anyone who has been exempted from being an Interested Person by any rule,
regulation or order of the Commission), and (y) against whom none of such
actions, suits or other proceedings or another action, suit or other proceeding
on the same or similar grounds is then or has been pending.

As used in this Section 4, the words "claim," "action," "suit" or "proceeding"
shall apply to all claims, actions, suits, proceedings (civil, criminal,
administrative or other, including appeals), actual or threatened; and the word
"liability" and "expenses" shall include without limitation, attorneys' fees,
costs, judgments, amounts paid in settlement, fines, penalties and other
liabilities.

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

The trustees and officers of the Registrant are covered by an Investment Trust
Errors and Omission policy in the aggregate amount of $20,000,000 (with a
maximum deductible of $500,000) against liability and expenses of claims of
wrongful acts arising out of their position with the Registrant, except for
matters which involved willful acts, bad faith, gross negligence and willful
disregard of duty (i.e., where the insured did not act in good faith for a
purpose he or she
reasonably believed to be in the best interest of Registrant or where he or she
shall have had reasonable cause to believe this conduct was unlawful).

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to the officers, trustees or controlling persons of the
Registrant pursuant to the Declaration of Trust of the Registrant or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by an officer or trustee or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such officer, trustee or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of
whether such indemnification by it is against public policy as expressed in the
Act and will be governed by the final adjudication of such issue.
