Is it Time for a Financial Check-Up?

Now is a great time to sit down with your financial adviser and review your
financial plan. How can you make sure that your investment strategy is strong
enough to provide the income you need today and versatile enough to change as
your goals do? Here are some guidelines:

 .  Make sure you and your adviser understand your current situation. How have
   your goals, objectives and risk profile changed? What are your current tax
   concerns, interests, lifestyle?

 .  Revisit your current investment choices. If the value of one portion of your
   portfolio has grown substantially, it may be time to rebalance asset classes.

 .  Determine how your asset mix will be implemented. Changing your asset
   allocation is generally a gradual process. Make sure you and your adviser
   have a clear understanding of each other's responsibilities. Define and
   discuss what you want in terms of support from your adviser.

 .  Keep revisiting your plan. Don't assume that once you've revised your plan
    and reallocated your portfolio the process is finished.

It's recommended that you meet at least once a year with your financial adviser
- -- and usually more if there have been significant changes in interest rates,
tax laws, retirement plan distributions, lifestyle or health.

Even if things haven't changed, it makes good financial sense to keep in touch
with your adviser.

Dear Shareholder

Chairman of the Board

Wealth takes a lifetime to build. Once achieved, it should be preserved.

I'm pleased to share with you this performance report for the Nuveen Kansas,
Missouri and Wisconsin municipal bond funds. Over the past 12 months, each of
the funds continued to perform well and meet their objectives of providing you
with attractive tax-free income and strong after-tax total returns.

For many of our shareholders, this annual report represents the first time you
have received a consolidated report covering performance data for other Nuveen
funds in addition to your own. These consolidated reports are part of our
continuing efforts to control fund expenses; we achieve greater economies of
scale for our shareholders through reducing paper, printing and mailing costs.
By consolidating reports by region and incorporating several funds into one
booklet, we have lowered these administrative expenses and made owning shares in
a Nuveen fund more cost-efficient for you.

The Economy in Review

Fixed-income investments enjoyed bullish performance over the past year, as
declining interest rates and low inflation spurred a bond market rally. The
equity markets also exhibited continued strength despite recent volatility
sparked by Asia's financial problems and their possible effects on U.S.
corporate earnings. Although interest rates have trended slightly upward in
recent months, a year-to-date comparison shows that today's rates are
significantly lower than they were one year ago. As shown in the accompanying
chart, between the end of May 1997 and May 1998, the yield on the Bond Buyer 40,
an unmanaged index of long-term municipal bonds, fell from 5.74% to 5.22%.
                             
Much of the decline in interest rates resulted from expectations that the
financial problems of Asia would restrain the prices of imported goods and
reduce foreign demand for U.S. products and services, thereby keeping inflation
at moderate levels. These inflation expectations were largely fulfilled, as the
Consumer Price Index rose only 1.5% for the 12 months ended May 1998, remaining
at one of its lowest levels in years.

The Asian situation also provided additional strength to the bond market rally,
as many investors made a "flight to quality" by moving assets into high-quality
U.S. bonds in the face of the uncertainty in that region.

In coming months, we will continue to watch closely several key factors that are
likely to affect the future of the economy, including the demand for goods and
services, the availability of qualified employees, the strength of the dollar,
and indications from the Federal Reserve. With many investors still waiting for
the full impact of Asia's difficulties to show up in U.S. economic statistics,
the potential long-term effect of this crisis on American markets continues to
cause concern. We expect that the development of these factors will continue to
influence the tone of the fixed-income markets during the remainder of the year.

Municipal Market Review

As interest rates continued to decline over the past year, bond prices rose.
This price appreciation for the bonds in our portfolios contributed to strong
total returns for the year.

Another major factor in bond performance over the last 12 months was the
continued strength of the U.S. economy, which helped boost the credit quality of
many municipal bonds. With the improvements in the fundamental financial health
of many municipalities and revenue projects financed by bonds, major credit
rating agencies upgraded the credit quality of thousands of issuers over the
past year, while downgrading relatively few. These boosts in credit quality also
contributed to the funds' performance as upgraded bonds increased in value.

The combination of low interest rates and a strong economy set new issuance on a
record pace and stimulated a dramatic increase in the refinancing of existing
bonds as issuers sought to lower their interest costs. The first quarter of 1998
saw $68 billion of new municipal issuance, up 70% from the same period in 1997.
The flood of new issues continued with May's long-awaited sale of the first
segment of Long Island (New York) Power Authority's $7 billion offering, the
largest issuance in municipal bond history. Although the nationwide supply of
municipal bonds remained heavy, the supply of bonds in each state varied
according to local economic conditions. This level of issuance highlights the
value of Nuveen's expertise in the municipal market, as our portfolio management
teams worked diligently to sift through the available issues to select those
undervalued securities that would help the funds achieve their investment
objectives.

"Another major factor in bond performance over the last 12 months was the
 continued strength of the U.S. economy, which helped boost the credit quality
 of many municipal bonds."

Diversification: The Key
to a Better Portfolio

In view of current market conditions, we believe that investors will find
diversification to be an increasingly important investment strategy in the
months ahead. An appropriately diversified portfolio -- one that balances
different types of investments, levels of risk and tax management -- can help
cushion your portfolio against volatility and enhance your return potential.

Many investors select Nuveen's municipal bond funds because their emphasis
on dependable tax-free income and attractive after-tax returns makes them ideal
for building and sustaining long-term financial security. These funds also work
well with other Nuveen investments to create the foundation of a diversified,
well-balanced portfolio. In fact, recent studies by Nuveen Research have found
that portfolios combining municipal bonds and stocks generated higher after-tax
returns with lower levels of risk than similar portfolios combining stocks and
Treasury or corporate bonds.

We encourage you to talk to your financial adviser about Nuveen's range of
equity and balanced funds, including the Nuveen European Value Fund. This new
equity mutual fund offers a portfolio of quality European company stocks for
investors seeking long-term growth potential and international diversification.
The fund is just one of an ever-expanding range of Nuveen products and services
designed to help investors achieve diversification while building a tax-
efficient, risk-sensitive investment portfolio. If you'd like to learn more
about the Nuveen European Value Fund or any of our other investments, contact
your financial adviser or call Nuveen Investor Services at (800) 257-8787 for a
prospectus. Please read the information carefully before you invest.

When seeking quality investment solutions that withstand the test of time, we
hope that you continue to think of Nuveen. Today, more than ever, you can count
on Nuveen for a wide range of investments that can help you build a well-
balanced portfolio designed to achieve your financial goals. We thank you for
your continued confidence in us and our family of investments.

Sincerely,

/s/ Timothy R. Schwertfeger

Chairman of the Board

Nuveen Flagship Kansas Municipal Bond Fund

Portfolio Manager's Comments

Portfolio Manager Mike Davern discusses fund performance,
the municipal market, and key investment strategies for the Kansas fund.

Comments cover the one-year period ended May 31, 1998 and all
performance statistics are quoted for Class A shares on net asset value.

State Economic and Market Review

Reflecting the national trend, Kansas enjoyed both economic and employment
growth over the last year. The state's municipal market was remarkably active
for the first half of 1998, offering $904 million dollars of new issuance,
approximately 86% more than the same period last year. Should issuance continue
at this pace through the year, 1998 may be the first year to match the
historically high issuance levels experienced in 1992 and 1993. Education,
general purpose, health care and utility offerings continue to dominate new
issue volume, representing approximately 72% of issuance.

Fund Performance

For the year ended May 31, 1998, the total return on net asset value for the
Kansas Municipal Bond Fund was 9.32%, which is equivalent to a taxable return of
12.21% for investors in the 35.5% combined federal and state income tax bracket.
The fund's total return was in line with the annual return of 9.38% posted by
the unmanaged Lehman Brothers Municipal Bond Index, and significantly
outperformed its Lipper peer group average of 8.0%. The Kansas Municipal Bond
Fund was also ranked third of the 12 Kansas municipal bond funds followed by
Lipper. In addition, the fund provided a competitive tax-free yield of 4.55%,
which translates to a taxable yield of 7.05% for investors in the 35.5% combined
federal and state income tax bracket. Thanks to good call protection and a
number of higher-yielding bonds, the fund's dividend held steady through the
declining interest rate environment.

Key Strategies

There were several elements contributing to the fund's performance during the
past year. First was the Kansas fund's mid-range portfolio duration, which kept
performance in line with the index. Duration is a measure of the fund's price
volatility in relation to changes in interest rates. In addition to maintaining
a moderate duration, we focused on the call protection of the fund, avoiding
issues that would be called away in the event of a near-term change in interest
rates and could (if called away) affect income levels. With that in mind, we
avoided securities with shorter call dates, instead finding value in certain
well-structured health care issues, and in lower-rated but still investment-
quality securities. Nuveen's diligent research team helps us find these lower-
rated bonds that offer competitive yields and solid financial positions.

In addition, we felt that bonds in the 20-30 year maturity range seldom offered
enough incremental yield for taking on the additional interest rate risk
associated with these longer-maturity bonds. Instead, we sought attractive
opportunities among bonds with maturities of 15-20 years, which offered the best
values given their historical levels of volatility.

As of May 31, 1998, the fund's sector holdings were well-diversified, with 20%
of the portfolio invested in health care debt, 20% in limited tax obligation
issues, 13% in U.S. guaranteed bonds and 12% in multifamily housing securities.

Outlook for the Future

Going forward, we expect conditions in which we can extend the duration of the
portfolio, as well as further enhance its already good call protection.
Presently, narrow yield spreads between lower- and higher-rated securities
provide little reward for the incremental credit risk associated with lower-
rated bonds. However, we plan to take advantage of any BBB-rated securities with
competitive yields that become available over the next year. Overall, we will
continue to maintain the fund's current healthy diversification, which should be
aided by improving supply.

Nuveen Flagship Missouri Municipal Bond Fund

Portfolio Manager's Comments

Portfolio Manager Mike Davern discusses fund performance,
the municipal market, and key investment strategies for the Missouri fund.

Comments cover the one-year period ended May 31, 1998 and all
performance statistics are quoted for Class A shares on net asset value.




State Economic and Market Review

Missouri confirmed its AAA credit quality status as a municipal issuer with
another year of sound financial operations and economic growth. The state ended
fiscal year 1997 with a budget stabilization fund totaling approximately $370
million, or nearly 4% of general fund revenues. The general fund, fueled by
strong individual income tax and sales/use tax revenues, increased 18% to $1.7
billion. High levels of economic growth between 1995 and 1997 and increasing
personal incomes resulted in income tax revenues that surpassed the
constitutional state limit, and taxpayers were subsequently rewarded with a
refund totaling $695 million.

Missouri's economy remains diversified, with recent declines in manufacturing
employment replaced by job gains in the services sector. Lease revenue debt,
which constitutes nearly one-third of total bond issuance, is an important
component of financing state capital programs. Missouri debt should continue to
attract attention, as new issue volume-in line with national municipal
trends-increased 94% during the first quarter of 1998.

Fund Performance

For the year ended May 31, 1998, the total return on net asset value for the
Missouri Municipal Bond Fund was 9.32%, which is equivalent to a taxable return
of 12.18% for investors in the 35.1% combined federal and state income tax
bracket. The fund's total return was in line with the annual return of 9.38%
posted by the unmanaged Lehman Brothers Municipal Bond Index, and outperformed
its Lipper peer group average of 8.65%. The Missouri Municipal Bond Fund was
also ranked fourth of the 23 Missouri municipal bond funds followed by Lipper.
In addition, the fund provided a competitive tax-free yield of 4.40%, which
translates to a taxable yield of 6.78% for investors in the 35.1% combined
federal and state income tax bracket.

Key Strategies

There were several elements contributing to the fund's performance during the
past year. First was the Missouri fund's mid-range portfolio duration, which
kept performance in line with the index. Duration is a measure of the fund's
price volatility in relation to changes in interest rates. In addition to
maintaining a moderate duration, we focused on the call protection of the fund,
avoiding issues that would be called away in the event of a near-term change in
interest rates and may affect income levels. With that in mind, we found value
in several call-protected housing bond issues, as well as in tax obligation
debt.

In addition, we felt that bonds in the 20-30 year maturity range seldom offered
enough incremental yield for taking on the additional interest rate risk
associated with these longer-maturity bonds. Instead, we sought attractive
opportunities among bonds with maturities of 15-20 years, which offered the best
values given their historical levels of volatility.

As of May 31, 1998, the fund's sector holdings were well-diversified, in part
thanks to steady supply during the past year. Specifically, 17% of the portfolio
was invested in limited tax obligation bonds, 17% in health care securities, 13%
in U.S. guaranteed bonds and 11% in multifamily housing debt.

Outlook for the Future

Going forward, we expect conditions in which we can maintain the duration of the
portfolio, as well as its favorable call protection. Higher-quality issues will
continue to dominate the portfolio, because narrow yield spreads between lower-
and higher-rated securities provide little reward for assuming the increased
credit risk associated with lower-quality bonds. Overall, we will continue to
maintain the fund's current healthy diversification, which should be aided by
continuing strong supply.

Nuveen Flagship Wisconsin Municipal Bond Fund

Portfolio Manager's Comments

Portfolio Manager Mike Davern discusses fund performance,
the municipal market, and key investment strategies for the Wisconsin fund.

Comments cover the one-year period ended May 31, 1998 and all
performance statistics are quoted for Class A shares on net asset value.


State Economic and Market Review

Wisconsin boasted another strong fiscal year in 1997, resulting in a credit
rating upgrade for the state's general obligation debt by Standard and Poor's.
Fueled by strong national economic growth, financial operations remained stable,
with state tax revenues increasing 7.7% during 1997. Manufacturing employment,
representing 24% of total employment, reached an all-time high in August of
1997.

Although the state's debt burden is moderate overall, $450 million in short-term
debt has been issued so far during 1998 -- the largest short-term borrowing year
since 1992. In addition, new issue volume was up 26% during the first quarter of
1998 over the same period last year. Additional issuance during 1998 should
continue to attract investors in the municipal bond market. Despite the new
issuance, strict legislative requirements have limited the amount of new
issuance that is exempt from state income taxes. Given the high state income tax
rate and limited amount of state tax-exempt issuance, finding value in the
Wisconsin market remains a challenge. 

Fund Performance

The fund performed well over the past year, generating a total return on net
asset value of 10.19%, which is equivalent to a taxable return of 13.08% for
investors in the 35.7% combined federal and state income tax bracket. The fund's
total return outperformed the annual return of 9.38% posted by the unmanaged
Lehman Brothers Municipal Bond Index and far surpassed its Lipper peer group
average of 8.46%. The Wisconsin Municipal Bond Fund also ranked sixth among the
74 municipal bond funds in the Lipper "other states" category. In addition, the
fund provided a competitive tax-free yield of 4.66%, which is equivalent to a
taxable yield of 7.25% for investors in the 35.7% combined federal and state
income tax bracket. This excellent performance is quite impressive given the
limited amount of issuance that is double tax-exempt in the state.

Key Strategies

The fund's strong performance was due in part to its long portfolio duration,
which is a measure of price volatility in reaction to changes in interest rates.
The fund's duration of 8.60 years was longer than the Lehman Index's average
duration of 7.11 years. The longer duration allowed the fund to better
participate in this year's market rally, although it would have been more
adversely affected had there been a market downturn. In addition to maintaining
a longer duration, we focused on the call protection of the fund, avoiding
issues that might be called away at an inopportune time in order to protect the
fund's strong income levels.

We also took advantage of Nuveen's diligent research team to find value in non-
rated and lower-rated investment-quality bonds. Nuveen Research helps us find
these lower-rated bonds that offer competitive yields and solid financial
positions. Bonds from U.S. territories also played an important role in the
fund's solid performance. Because these bonds are exempt from both federal and
Wisconsin state taxes, they helped support the portfolio when issuance of state
tax-exempt bonds was thin, and their recent price appreciation contributed to
the fund's strong total returns for the year.

In addition, we felt that bonds in the 20-30 year maturity range seldom offered
enough incremental yield for taking on the additional interest rate risk
associated with these longer-maturity bonds. Instead, we sought attractive
opportunities among bonds with maturities of 15-20 years, which offered the best
values given their historical levels of volatility.

As of May 31, 1998, the fund's sector holdings were heavily weighted toward
limited tax obligation securities, which are among the only double-tax-exempt
securities in the state. They made up 46% of the portfolio. Other key sectors
included long-term care facility bonds at 10%, multifamily housing securities at
10% and utility bonds at 9%.

Outlook for the Future

Going forward, we expect conditions in which we can maintain the duration of the
portfolio, as well as its excellent call protection. Lower investment-grade and
non-rated issues will continue to represent at least a third of the portfolio
until more state tax-exempt issuance makes it possible to find attractive
opportunities in a wider range of securities.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Flagship Multistate Trust IV:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of Nuveen Flagship Kansas Municipal Bond Fund, Nuveen
Flagship Missouri Municipal Bond Fund, and Nuveen Flagship Wisconsin Municipal
Bond Fund (collectively, the "Funds") (three of the portfolios constituting the
Nuveen Flagship Multistate Trust IV (a Massachusetts business trust)), as of May
31, 1998, and the related statements of operations, statements of changes in net
assets and the financial highlights for the year then ended. 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
statements and financial highlights for the Funds for the years ended May 31,
1997 and prior were audited by other auditors whose report dated July 11, 1997,
expressed an unqualified opinion on those financial statements and financial
highlights.

We conducted our audits in accordance with generally accepted auditing
standards. 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 May
31, 1998, 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 Kansas Municipal Bond Fund, Nuveen Flagship Missouri Municipal Bond
Fund, and Nuveen Flagship Wisconsin Municipal Bond Fund of the Nuveen Flagship
Multistate Trust IV as of May 31, 1998, and the results of their operations, the
changes in their net assets, and the financial highlights for the year then
ended, in conformity with generally accepted accounting principles.

Notes to Financial Statements

1. General Information and Significant Accounting Policies

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

The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Funds, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses.  This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.

After the close of business on January 31, 1997, Flagship Kansas Triple Tax
Exempt Fund ("Flagship Kansas"), Flagship Missouri Double Tax Exempt Fund
("Flagship Missouri") and Flagship Wisconsin Double Tax Exempt Fund ("Flagship
Wisconsin") reorganized into the Trust and were renamed Nuveen Flagship Kansas
Municipal Bond Fund ("Kansas"), Nuveen Flagship Missouri Municipal Bond Fund
("Missouri") and Nuveen Flagship Wisconsin Municipal Bond Fund ("Wisconsin").
Prior to these reorganizations, Flagship Kansas, Flagship Missouri and Flagship
Wisconsin were each sub-trusts of the Flagship Tax Exempt Funds Trust.

The Funds seek to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

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

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 May
31, 1998, Kansas and Wisconsin had outstanding delayed delivery purchase
commitments of $967,500 and $1,555,881, respectively. Missouri had no such
outstanding purchase commitments.

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 as a dividend monthly 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.

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, the Funds intend to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal and designated  state income taxes, 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 May 31,
1998, 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, 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 1% 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 for purchases of over $1 million and in other limited
circumstances.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap, 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 May 31, 1998.

Expense Allocation

Expenses of the Funds 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.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles 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.

Organizational Expenses

The organizational expenses incurred on behalf of Kansas and Wisconsin
(approximately $42,800 and $98,000, respectively) are being reimbursed to the
Adviser on a straight-line basis over a period of five years and three years,
respectively. As of May 31, 1998, all of the organizational expenses of Kansas
and $65,392 of the organizational expenses of Wisconsin have been reimbursed.

The Adviser may voluntarily agree to reimburse expenses from time to time, which
may be terminated at any time at its discretion.

Wealth takes
a lifetime
to build.
Once achieved,
it should be
preserved.

I'm pleased to share with you this performance report for your Nuveen municipal
bond fund. Over the past 12 months, each of the funds in this report continued
to perform well and meet their objectives of providing you with attractive tax-
free income and strong after-tax total returns.

For many of our shareholders, this annual report represents the first time you
have received a consolidated report covering performance data for other Nuveen
funds in addition to your own. These consolidated reports are part of our
continuing efforts to control fund expenses; we achieve greater economies of
scale for our shareholders through reducing paper, printing and mailing costs.
By consolidating reports by region and incorporating several funds into one
booklet, we have lowered these administrative expenses and made owning shares in
a Nuveen fund more cost-efficient for you.

The Economy in Review

Fixed-income investments enjoyed bullish performance over the past year, as
declining interest rates and low inflation spurred a bond market rally.


The equity markets also exhibited continued strength despite recent volatility
sparked by Asia's financial problems and their possible effects on U.S.
corporate earnings. Although interest rates have trended slightly upward in
recent months, a year-to-date comparison shows that today's rates are
significantly lower than they were one year ago. As shown in the accompanying
chart, between the end of May 1997 and May 1998, the yield on the Bond Buyer 40,
an unmanaged index of long-term municipal bonds, fell from 5.74% to 5.22%.

Much of the decline in interest rates resulted from expectations that the
financial problems of Asia would restrain the prices of imported goods and
reduce foreign demand for U.S. products and services, thereby keeping inflation
at moderate levels. These inflation expectations were largely fulfilled, as the
Consumer Price Index rose only 1.5% for the 12 months ended May 1998, remaining
at one of

its lowest levels in years. The Asian situation also provided additional
strength to the bond market rally, as many investors made a "flight to quality"
by moving assets into high-quality U.S. bonds in the face of the uncertainty in
that region.

In coming months, we will continue to watch closely several key factors that are
likely to affect the future of the economy, including the demand for goods and
services, the availability of qualified employees, the strength of the dollar,
and indications from the Federal Reserve. With many investors still waiting for
the full impact of Asia's difficulties to show up in U.S. economic statistics,
the potential long-term effect of this crisis on American markets continues to
cause concern. We expect that the development of these factors will continue to
influence the tone of the fixed-income markets during the remainder of the year.

Municipal Market Review

As interest rates continued to decline over the past year, bond prices rose.
This price appreciation for the bonds in our portfolios contributed to strong
total returns for the year.

Another major factor in bond performance over the last 12 months was the
continued strength of the U.S. economy, which helped boost the credit quality of
many municipal bonds. With the improvements in the fundamental financial health
of many municipalities and revenue projects financed by bonds, major credit
rating agencies upgraded the credit quality of thousands of issuers over the
past year, while downgrading relatively few. These boosts in credit quality also
contributed to the funds' performance as upgraded bonds increased in value.

The combination of low interest rates and a strong economy set new issuance on a
record pace and stimulated a dramatic increase in the refinancing of existing
bonds as issuers sought to lower their interest costs. The first quarter of 1998
saw $68 billion of new municipal issuance, up 70% from the same period in 1997.
The flood of new issues continued with May's long-awaited sale of the first
segment of Long Island (New York) Power Authority's $7 billion offering, the
largest issuance in municipal bond history. Although the nationwide supply of
municipal bonds remained heavy, the supply of bonds in each state varied
according to local economic conditions. This level of issuance highlights the
value of Nuveen's expertise in the municipal market, as our portfolio management
teams worked diligently to sift through the available issues to select those
undervalued securities that would help the funds achieve their investment
objectives.

Diversification: The Key to a Better Portfolio

In view of current market conditions, we believe that investors will find
diversification to be an increasingly important investment strategy in the
months ahead. An appropriately diversified portfolio - one that balances
different types of investments, levels of risk and tax management - can help
cushion your portfolio against volatility and enhance your return potential.

Many investors select Nuveen's municipal bond funds because their emphasis on
dependable tax-free income and attractive after-tax returns makes them ideal for
building and sustaining long-term financial security. These funds also work well
with other Nuveen investments to create the foundation of a diversified, well-
balanced portfolio. In fact, recent studies by Nuveen Research have found that
portfolios combining municipal bonds and stocks generated higher after-tax
returns with lower levels of risk than similar portfolios combining stocks and
Treasury or corporate bonds.

We encourage you to talk to your financial adviser about Nuveen's range of
equity and balanced funds, including the Nuveen European Value Fund. This new
equity mutual fund offers a portfolio of quality European company stocks for
investors seeking long-term growth potential and international diversification.
The fund is just one of an ever-expanding range of Nuveen products and services
designed to help investors achieve diversification while building a tax-
efficient, risk-sensitive investment portfolio. If you'd like to learn more
about the Nuveen European Value Fund or any of our other investments, contact
your financial adviser or call Nuveen Investor Services at (800) 257-8787 for a
prospectus. Please read the information carefully before you invest.

When seeking quality investment solutions that withstand the test of time, we
hope that you continue to think of Nuveen. Today, more than ever, you can count
on Nuveen for a wide range of investments that can help you build a well-
balanced portfolio designed to achieve your financial goals. We thank you for
your continued confidence in us and our family of investments.

Sincerely,

Nuveen Flagship Kentucky Municipal Bond Fund

Portfolio Manager's Comments

Portfolio Manager Rick Huber discusses fund performance, the municipal market,
and key investment strategies for the Kentucky fund.

Comments cover the one-year period ended May 31, 1998 and all performance
statistics are quoted for Class A shares on net asset value.



State Economic and Market Review

Kentucky's stable financial and economic conditions continued through the first
half of 1998, as recognized by the state's AA credit rating from Standard &
Poor's. Although Kentucky has not issued general obligation debt since 1965, the
state actively issues appropriation-secured debt from several different 
agencies--all of which totaled $3 billion in issuance at fiscal year-end.

The commonwealth's new issue volume was up almost 15% during the first quarter
of 1998. Municipal bond investors anticipate a number of statewide projects
authorized for the 1996-1998 biennium, including $103 million of new debt to
fund new juvenile detention centers, state parks, and university projects. In
spite of this increased supply, good values were hard to find, as yield spreads
remained narrow between lower- and higher-rated securities.

Fund Performance

For the year ended May 31, 1998, the total return on net asset value for the
Kentucky Municipal Bond Fund was 9.00%, which is equivalent to a taxable return
of 11.93% for investors in the 35.1% combined federal and state income tax
bracket. The fund slightly underperformed the annual return of 9.38% posted by
the Lehman Brothers Municipal Bond Index, but surpassed its Lipper peer group
average of 8.55%. The discrepancy between the national Lehman Index and the
Lipper peer group average of Kentucky municipal bond funds highlights the
effects of the tight supply of long-term bonds in the Kentucky market. The
limited supply and high demand keep bond prices high and yields low compared
with other states that have better bond supplies to meet investor demand.

The fund maintained a portfolio duration similar to its benchmark (a 6.41
duration), which helped keep its performance in line with its peers despite the
difficulty in finding value in the market. Duration is a measure of the fund's
price volatility in relation to changes in interest rates.

Key Strategies

We worked during the year to improve the fund's diversification among different
sectors of the market and investment-grade credit quality levels. To that end,
we focused on reducing the fund's holdings in the health care sector, and at the
same time found attractive opportunities in some bonds issued by U.S.
territories (which are exempt from both federal and Kentucky state income
taxes). We also moved to improve the portfolio's protection against bond calls,
which decreases the likelihood that higher-paying bonds will be called away if
interest rate conditions change.

In addition, we felt that bonds in the 20-30 year maturity range seldom offered
enough incremental yield for taking on the additional interest rate risk
associated with these longer-maturity bonds. Instead, we sought attractive
opportunities among bonds with maturities of 15-20 years, which offered the best
values given their historical levels of volatility.

As of May 31, 1998, the fund's key sectors were limited tax obligation and
health care bonds, each of which comprised 23% of the portfolio. Other important
areas included utility bonds at 10% and U.S. guaranteed bonds at 9%.

Outlook for the Future

On July 1, 1998, Nuveen made several changes in the management of its mutual
funds to make more efficient use of staff resources and portfolio manager
expertise. As a result, Tom O'Shaughnessy assumed management responsibilities
for this fund. Tom is a 15-year veteran of Nuveen and an experienced investment
professional who has managed a range of other municipal bond funds.

Tom and his team anticipate a continued healthy state economy, which might
translate into strong bond supply in late 1998 or 1999. Until lower-rated bonds
offer more competitive yields, they will continue to seek value from small,
higher-rated bond issues. At the same time, they will continue to reduce the
fund's holdings in the health care sector and, in the event that bond supplies
and yield spreads improve, will attempt to extend portfolio duration somewhat.

Portfolio Manager's Comments

Portfolio Manager Rick Huber discusses fund performance, the municipal market,
and key investment strategies for the Kentucky Limited fund.

Comments cover the one-year period ended May 31, 1998 and all
performance statistics are quoted for Class A shares on net asset value.

State Economic and Market Review

Kentucky's stable financial and economic conditions continued through the first
half of 1998, as recognized by the state's AA credit rating from Standard &
Poor's. Although Kentucky has not issued general obligation debt since 1965, the
state actively issues appropriation-secured debt from several different
agencies--all of which totaled $3 billion in issuance at fiscal year-end.

The commonwealth's new issue volume was up almost 15% during the first quarter
of 1998. Kentucky municipal bond investors anticipate a number of statewide
projects authorized for the 1996-1998 biennium, including $103 million of new
debt to fund new juvenile detention centers, state parks, and university
projects. In spite of this increased supply, good values were hard to find, as
yield spreads remained narrow between lower- and higher-rated securities.

Fund Performance

For the year ended May 31, 1998, the total return on net asset value for the
Kentucky Limited Term Municipal Bond Fund was 6.53%, which is equivalent to a
taxable return of 8.97% for investors in the 35.1% combined federal and state
income tax bracket. The total return was in line with the annual return of 6.69%
posted by the unmanaged Lehman Brothers Five-Year Municipal Bond Index, and
surpassed the Lipper peer group average return of 5.71% for the short-
intermediate term municipal bond funds in the "other states" category. In
addition, the fund provided a competitive taxable equivalent yield of 6.01% for
investors in the 35.1% combined federal and state income tax bracket, and
maintained a steady dividend throughout the period.

Key Strategies

We worked this year to extend the fund's duration, a strategy that helped the
fund outperform its peers. Duration is a measure of the fund's price volatility
in relation to changes in interest rates. The fund's duration of 5.0 years was
longer than the Lehman Five-Year Municipal Bond Index's average duration of 4.05
years. The longer duration allowed the fund to better participate in this year's
market rally, although it would have been more adversely affected had there been
a market downturn. At the same time, we worked to improve the fund's
diversification among different sectors of the market and investment-grade
credit quality levels. To that end, we reduced the fund's holdings in the health
care sector, and at the same time found unique opportunities in the housing
sector.

In addition, we felt that high demand for bonds in the middle of the limited-
term maturity range reduced the selection of good values among those issues.
Instead, we sought attractive opportunities in longer-maturity bonds when
possible.

As of May 31, 1998, the fund was focused on two primary sectors: health care
(23%) and limited tax obligation bonds (22%). Other key holdings included
education and civic organization bonds at 14% and multifamily housing bonds at
10%.

Outlook for the Future

On July 1, 1998, Nuveen made several changes in the management of its mutual
funds to make more efficient use of staff resources and portfolio manager
expertise. As a result, Tom O'Shaughnessy assumed management responsibilities
for this fund. Tom is a 15-year veteran of Nuveen and an experienced investment
professional who has managed a range of other state and national municipal bond
funds.

Tom and his team anticipate a continued healthy state economy, which might
translate into strong bond supply in late 1998 or 1999. Until lower-rated bonds
offer more competitive yields, they will continue to seek value from small,
higher-rated bond issues. They believe the fund is well-positioned for the
coming year, although they will work toward reducing the fund's duration
slightly. At the same time, they expect the fund's steady cash flow to continue,
which will allow them to take advantage of good values and uncommon
opportunities that arise in the market.

Nuveen Flagship Michigan Municipal Bond Fund
Portfolio Manager's Comments

Portfolio Manager Mike Davern discusses fund performance, the municipal market,
and key investment strategies for the Michigan fund.

Comments cover the one-year period ended May 31, 1998 and all
performance statistics are quoted for Class A shares on net asset value.


State Economic and Market Review

Michigan's economy has remained healthy throughout 1997 and thus far in 1998,
resulting in credit upgrades for the state's general obligation debt by all
three major debt rating agencies. The upgrades were due in part to Michigan's
accumulated Budget Stabilization Fund reserves, which exceeded $1.2 billion in
1997. These reserves should provide a cushion against future economic downturns,
which are possible because of Michigan's continuing dependence on the cyclical
automobile manufacturing industry. Due in part to the strong national economy,
the state's unemployment rate has been lower than the national average for four
consecutive years, and per capita income has surpassed national averages for the
past two years.

Education spending remains Michigan's priority, with total state and local
funding for schools projected to grow to approximately $12 billion by 1999 - a
50% increase since 1990. Michigan's overall debt burden is manageable, despite a
doubling of new issuance volume during the first quarter of 1998. Investors can
expect additional debt issuance to fund the Michigan Department of
Transportation's Build Michigan II program, which is designed to finance the
rebuilding of the state's roads and bridges.

Fund Performance

For the year ended May 31, 1998, the total return on net asset value for the
Michigan Municipal Bond Fund was 8.95%, which is equivalent to a taxable return
of 11.69% for investors in the 34% combined federal and state income tax
bracket. The total return was in line with the annual return of 9.38% posted by
the Lehman Brothers Municipal Bond Index, and surpassed the average return of
8.72% for the peer group of Michigan municipal bond funds tracked by Lipper
Analytical Service, a nationally recognized performance measurement service. In
addition, the fund provided a competitive yield of 4.28%, which is Equivalent
to a taxable yield of 6.48% for investors in the 34% combined federal and state
income tax bracket.

Key Strategies

There were several elements contributing to the fund's performance during the
past year. First was the Michigan fund's conservative structure and shorter
portfolio duration going into the year, which kept the fund largely in line with
its peer group. Duration is a measure of the fund's price volatility in relation
to changes in interest rates. To offset its shorter duration, we focused on
maintaining longer call protection, avoiding issues that would hinder portfolio
performance by being called away because of a near-term change in interest
rates. Education bonds were plentiful this past year, while hospital bonds were
comparatively scarce. Nonetheless, we found good value in both areas in the past
year.

In addition, we felt that bonds in the 20-30 year maturity range seldom offered
enough incremental yield for taking on the additional interest rate risk
associated with these longer-maturity bonds. Instead, we sought attractive
opportunities among bonds with maturities of 15-20 years, which offered the best
values given their historical levels of volatility.

As of May 31, 1998, the fund's sector holdings were weighted toward health care
issues, which represented 24% of the portfolio. Other key sectors included U.S.
guaranteed bonds representing 17% of the portfolio, 16% in limited tax
obligation issues, and another 16% in general tax obligation issues.

Outlook for the Future

Going forward, we expect conditions in which we can lengthen the duration of the
portfolio and enhance its already favorable call protection. Higher-quality
issues will continue to dominate the portfolio, because lower-rated securities
currently provide little reward for assuming the additional credit risk.
Overall, we will continue to maintain the fund's current healthy
diversification, which should be aided by continuing strong supply.

Nuveen Flagship Ohio Municipal Bond Fund
Portfolio Manager's Comments

Portfolio Manager Walt Parker discusses fund performance, the municipal market,
and key investment strategies for the Ohio fund.

Comments cover the one-year period ended May 31, 1998 and all
performance statistics are quoted for Class A shares on net asset value.


State Economic and Market Review

Ohio's municipal market remained solid through the first half of 1998 with $3.6
billion of new issuance, a 54.4% increase over 1997 levels. General purpose,
health care and education offerings continue to dominate new issue volume,
representing approximately 66% of issuance.

Ohio school district financing continues to occupy the attention of municipal
market participants, as voters rejected a one percent sales tax increase
proposal intended to provide additional school funding last May. Also rejected
was a proposal that would have allowed the legislature to issue general
obligation bonds for school projects. As a consequence, bonds enhanced by the
Ohio School District Credit Enhancement Program continue to carry relatively
diverse ratings in comparison to bonds from other states with similar programs.

Fund Performance

The fund performed well, generating a total return on net asset value of 8.76%,
which is equivalent to a taxable return of 11.76% for investors in the 35.8%
combined federal and state income tax bracket. The fund outperformed the average
return of 8.57% for the peer group of Ohio municipal bond funds tracked by
Lipper Analytical Service, a nationally recognized performance measurement
service. However, it slightly underperformed the return of 9.38% posted by the
Lehman Brothers Municipal Bond Index, primarily due to its shorter duration of
6.44 years, compared with the Lehman Index duration of 7.11 years. Duration is a
measure of price volatility in reaction to changes in interest rates. Although
the shorter duration hindered the fund's ability to participate in this year's
market rally, it helped protect the fund from volatility and would help it to
outperform in a market downturn.

Key Strategies

Since the Ohio Municipal Bond Fund is among Nuveen's largest municipal funds, we
must buy bonds in larger blocks to affect the portfolio's performance.
Therefore, we looked to large issuers and heavy-issuance sectors to implement
many of our strategies during the year.

Through our in-depth research, we continued to uncover value investing
opportunities, as several portfolio holdings received credit upgrades or were
pre-refunded during the year. In a pre-refunding, bonds are essentially paid off
by their issuer and backed by U.S. Treasury securities, which typically leads to
price appreciation. Nuveen's diligent research team helped us find those
securities with the potential for credit upgrades and pre-refundings. That
strategy paid off this year, as evidenced by the fund's 68% holding in AAA rated
bonds and attractive total returns.

In addition, we felt that bonds in the 20-30 year maturity range seldom offered
enough incremental yield for taking on the additional interest rate risk
associated with these longer-maturity bonds. Instead, we sought attractive
opportunities among bonds with maturities of 15-20 years, which offered the best
values given their historical levels of volatility.

As of May 31, 1998, the fund's sector holdings were well-diversified, with 20%
of the portfolio invested in U.S. guaranteed issues (which are mostly pre-
refunded bonds), 18% in general tax obligation bonds, 15% in health care issues
and 11% in utility bonds.

Outlook for the Future

On July 1, 1998, Nuveen made several changes in the management of its mutual
funds to make more efficient use of staff resources and portfolio manager
expertise. As a result, Tom Futrell assumed management responsibilities for this
fund. Tom is a 15-year veteran of Nuveen and an experienced investment
professional who has managed a range of other municipal bond funds.

Tom and his team anticipate a continued strong state economy in the near future.
In addition, they expect the yield spread between lower- and higher-quality
bonds to remain tight. With that in mind, they will continue to seek value from
overlooked sectors and issues offering higher yields or strong appreciation
potential. Particular areas they will be monitoring include housing bonds and
issues subject to the alternative minimum tax (AMT), which offer better
opportunities in the current market environment.

Report of Independent Public Accountants


To the Board of Trustees and Shareholders of
Nuveen Flagship Multistate Trust IV:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of Nuveen Flagship Kentucky Municipal Bond Fund,
Nuveen Flagship Kentucky Limited Term Municipal Bond Fund, Nuveen Flagship
Michigan Municipal Bond Fund and Nuveen Flagship Ohio Municipal Bond Fund 
(collectively, the "Funds") (four of the portfolios constituting the Nuveen
Flagship Multistate Trust IV (a Massachusetts business trust)), as of May 31,
1998, and the related statements of operations, statements of changes in net
assets and the financial highlights for the year then ended. 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
statements and financial highlights for the Funds for the years ended May 31,
1997 and prior were audited by other auditors whose report dated July 11, 1997,
expressed an unqualified opinion on those financial statements and financial
highlights.

We conducted our audits in accordance with generally accepted auditing
standards. 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 May
31, 1998, 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 Kentucky Municipal Bond Fund, Nuveen Flagship Kentucky Limited Term
Municipal Bond Fund, Nuveen Flagship Michigan Municipal Bond Fund and Nuveen
Flagship Ohio Municipal Bond Fund of the Nuveen Flagship Multistate Trust IV as
of May 31, 1998, and the results of their operations, the changes in their net
assets, and the financial highlights for the year then ended, in conformity with
generally accepted accounting principles.

1. General Information and Significant Accounting Policies

The Nuveen Flagship Multistate Trust IV (the "Trust") is an open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust comprises the Nuveen Flagship Kentucky Municipal Bond Fund, the Nuveen
Flagship Kentucky Limited Term Municipal Bond Fund, the Nuveen Flagship Michigan
Municipal Bond Fund and the Nuveen Flagship Ohio Municipal Bond Fund (the
"Funds"), among others. The Trust was organized as a business trust on July 1,
1996.

The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Funds, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.

After the close of business on January 31, 1997, Flagship Kentucky Triple Tax
Exempt Fund ("Flagship Kentucky") and Flagship Kentucky Limited Term Municipal
Bond Fund ("Flagship Kentucky Limited Term") were reorganized into the Trust and
renamed Nuveen Flagship Kentucky Municipal Bond Fund ("Kentucky") and Nuveen
Flagship Kentucky Limited Term Municipal Bond Fund ("Kentucky Limited Term"),
respectively. Prior to these reorganizations, each Fund was a sub-trust of the
Flagship Tax Exempt Funds Trust.

After the close of business on January 31, 1997, Flagship Michigan Triple Tax
Exempt Fund ("Flagship Michigan") and Nuveen Michigan Tax-Free Value Fund
("Nuveen Michigan") reorganized into Nuveen Flagship Michigan Municipal Bond
Fund ("Michigan"). Prior to the reorganization, Flagship Michigan was a 
sub-trust of the Flagship Tax Exempt Funds Trust while Nuveen Michigan was a
series of the Nuveen Multistate Tax-Free Trust. Nuveen Michigan had a fiscal
year end of January 31 prior to being reorganized into Nuveen Flagship Michigan
which has retained the fiscal year end of Flagship Michigan.

After the close of business on January 31, 1997, Flagship Ohio Double Tax Exempt
Fund ("Flagship Ohio") and Nuveen Ohio Tax-Free Value Fund ("Nuveen Ohio")
reorganized into Nuveen Flagship Ohio Municipal Bond Fund ("Ohio"). Prior to the
reorganization, Flagship Ohio was a sub-trust of the Flagship Tax Exempt Funds
Trust while Nuveen Ohio was a series of the Nuveen Tax-Free Bond Fund, Inc.
Nuveen Ohio had a fiscal year end of February 28 prior to being reorganized into
Nuveen Flagship Ohio which has retained the fiscal year end of Flagship Ohio.

The Funds seek to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

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

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 May
31, 1998, Kentucky Limited Term and Michigan had outstanding when-issued
purchase commitments of $500,000 and $2,861,460, respectively. There were no
such outstanding purchase commitments in Kentucky and Ohio.

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.

<PAGE>
 
Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared as a dividend monthly 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.

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, the Funds intend to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal and designated state income taxes, 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 May 31,
1998, 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. Kentucky, Michigan and Ohio 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 1%
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
for purchases of over $1 million and in other limited circumstances.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap, 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 May 31, 1998.

Expense Allocation

Expenses of the Funds 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.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles 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.

Organizational Expenses

The organizational expenses incurred on behalf of Kentucky Limited Term
(approximately $29,400) are being reimbursed to the Adviser on a straight-line
basis over a period of three years. As of May 31, 1998, $19,595 has been
reimbursed.
