MINNESOTA MUNICIPAL INCOME PORTFOLIO

Minnesota Municipal Income Portfolio is a non-diversified, closed-end 
investment company. The fund's investment objective is to provide high 
current income exempt from both regular federal income tax and state of 
Minnesota personal income tax, consistent with preservation of capital. To 
realize this objective, the fund invests in a wide range of Minnesota 
municipal securities rated investment grade or of comparable quality when 
purchased. These securities may include municipal derivative securities, such 
as inverse floating rate and inverse interest-only municipal securities, 
which may be more volatile than traditional municipal securities in certain 
market conditions. As with other mutual funds, there can be no assurance this 
fund will achieve its investment objective. Since its inception on June 25, 
1993, the fund has been rated Af by Standard & Poor's Mutual Funds Rating 
Group (S&P).* Fund shares trade on the American Stock Exchange and the 
Chicago Stock Exchange under the symbol MXA.

*THE FUND IS RATED Af, WHICH MEANS THE FUND'S INVESTMENTS HAVE AN OVERALL CREDIT
QUALITY OF A. CREDIT QUALITIES ARE ASSESSED BY STANDARD & POOR'S MUTUAL FUNDS
RATING GROUP. S&P DOES NOT EVALUATE THE MARKET RISK OF AN INVESTMENT WHEN

                          AVERAGE ANNUAL TOTAL RETURNS


PERIODS ENDED JANUARY 31, 1996

[GRAPH]

Average annual total return figures are through January 31, 1996, and are 
based on the change in net asset value (NAV) and reflect the reinvestment of 
distributions but do not reflect sales charges. NAV-based performance is used 
to measure investment management results.

Average annual total return figures based on the change in market price for 
the one-year and since inception periods ended January 31, 1996, were 15.74% 
and 0.25%. These figures also assume reinvested distributions and do not 
reflect sales charges.

The Lipper General Municipal Bond Funds: Leveraged Average represents the 
average total return, with distributions reinvested, of similar funds as 
characterized by Lipper Analytical Services.

Past performance does not guarantee future results. The investment return and 
market value of an investment will fluctuate so that fund shares, when sold, 
may be worth more or less than their original cost.

March 15, 1996

Dear Shareholders:

THE NET ASSET VALUE TOTAL RETURN FOR MINNESOTA MUNICIPAL INCOME PORTFOLIO FOR 
THE ONE-YEAR PERIOD ENDED JANUARY 31, 1996, WAS 27.27%.* This assumes 
distributions were reinvested and does not include sales charges. In 
comparison, the Lipper General Municipal Bond Funds: Leveraged Average had a 
return of 18.55% during the same one-year period. The fund's higher return 
was primarily due to its longer effective duration which resulted from its 
holdings of inverse floating rate and inverse interest-only municipal 
securities, which are discussed further on page 3. This longer effective 
duration resulted in greater price volatility which proved beneficial in last 
year's declining interest rate environment. Based on market price, the fund's 
total return for the one-year period ended January 31 was 15.74%, which 
assumes distributions were reinvested and does not include sales charges. 

THE FUND'S NET ASSET VALUE INCREASED FROM $11.96 ON JANUARY 31, 1995, TO 
$14.32 ON JANUARY 31, 1996. The fund, along with other municipal bond 
investments, was well-rewarded during the year due to decreasing interest 
rates and declining supplies of both new municipal bond issues and 
outstanding municipal bonds. Municipal investors enjoyed strong returns 
despite competition from a robust stock market and ongoing concerns about 
proposed tax reforms (see page 7 for more information). Although these 
factors caused the municipal bond market to slightly lag the Treasury bond 
market, on an after-tax basis most

AND MARKET VALUE OF AN INVESTMENT WILL FLUCTUATE SO THAT FUND SHARES, WHEN 
SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

municipal investors likely found their tax-exempt yields to be higher than 
the yields of their taxable counterparts. Although we expect to see further 
market volatility in 1996 - due to the ongoing tax-reform debate - we believe 
the municipal market will benefit this year from a declining supply of 
outstanding bonds and a strong demand for municipal issues.

DUE TO A REDUCTION IN THE FUND'S NET INVESTMENT INCOME, THE FUND'S COMMON 
MONTHLY DISTRIBUTION WAS REDUCED FROM 6.9375 CENTS PER SHARE TO 6.3125 CENTS 
PER SHARE BEGINNING IN DECEMBER. The fund had been paying out to common and 
preferred shareholders more than it was earning; therefore, we had been 
drawing from the fund's dividend reserve to help maintain the common stock 
dividend. As a result, the fund's Dividend Committee lowered the common stock 
dividend to bring it in line with the fund's actual earnings. Since December 
when the dividend was reduced, we have been earning the 6.3125 cents per 
share dividend. 

THE DROP IN THE FUND'S INCOME WAS LARGELY BECAUSE WE PURCHASED A 3% POSITION 
IN FLOATING RATE MUNICIPAL SECURITIES TO OFFSET THE PRICE VOLATILITY OF A 
PORTION OF THE FUND'S INVERSE FLOATING RATE MUNICIPAL SECURITIES.  Both the 
inverse floating rate and inverse interest-only securities, which represented 
approximately 8% of

PREFERRED STOCK

Preferred stock pays dividends at a specified 
rate and has preference over common stock in 
the payments of dividends and the liquidation 
of assets. Rates paid on preferred stock are 
reset every seven days and are based on 
short-term tax-exempt interest rates. Preferred 
shareholders accept these short-term rates in 
exchange for low credit risk (shares of 
preferred stock are rated AAA by Moody's and 
S&P) and high liquidity (shares of preferred 
stock trade at par and are remarketed every 
seven days). The proceeds from the sale of 
preferred stock are invested at intermediate- 
and long-term tax-exempt rates. Because these 
intermediate- and long-term rates are normally 
higher than the short-term rates paid on 
preferred stock, common shareholders benefit by 
receiving higher dividends and/or an increase 
to the dividend reserve. However, the risk of 
having preferred stock is that if short-term 
rates rise higher than intermediate- and 
long-term rates, creating an inverted yield 
curve, common shareholders may receive a lower 
rate of return than if their fund did not have 
any preferred stock outstanding. This type of 
economic environment is unusual and 
historically has been short term in nature. 
Investors should also be aware that the 
issuance of preferred stock results in the 
leveraging of common stock which increases the 
volatility of both the net asset value of the 
fund and the market value of shares of common 
stock.

total assets on January 31, assist the fund in achieving its objective of
earning high current income. However, these securities also have a
disproportionate impact on the fluctuations in the fund's net asset value and
income level. When interest rates rise, the value of and income from these
securities could decline to a greater extent than traditional municipal
securities. However, as rates fall, as they did in 1995, the increased
volatility of these securities can have a disproportionately positive impact on
the fund's net asset value and income. While the purchase of the floating rate
securities lessened the fund's volatility, it also reduced the income generated
by the inverse floating rate securities. 

IN ADDITION, OVER THE PAST 12 MONTHS THE FUND'S ISSUANCE OF PREFERRED STOCK HAS
ADDED SLIGHTLY LESS INCOME THAN IN THE PAST; HOWEVER, IT IS STILL ALLOWING US TO
PAY A HIGHER DIVIDEND TO COMMON STOCK SHAREHOLDERS THAN IF THE FUND DID NOT HAVE
PREFERRED STOCK OUTSTANDING. While long-term interest rates have remained higher
than short-term rates, income in the fund has decreased because long-term tax-
exempt rates have fallen to a greater extent than short-term tax-exempt rates,
creating somewhat of a flatter yield curve. This had the effect of keeping the
cost of the fund's preferred stock relatively high and reducing the income
available for common shareholders. Typically, the money raised by the issuance
of preferred stock is reinvested by the fund at long-term rates that are higher
than

EFFECTIVE DURATION

Effective duration estimates the interest rate 
risk of a security, in other words, how much 
the value of the security is expected to change 
with a given change in interest rates. The 
longer a security's effective duration, the 
more sensitive its price is to changes in 
interest rates. For example, if interest rates 
increased by 1%, the market value of a bond 
with an effective duration of five years would 
decrease by about 5%, with all other factors 
being constant.

It is important to understand that, while a 
valuable measure, effective duration is based 
on certain assumptions and has several 
limitations. It is more effective as a measure 
of interest rate risk when interest rate 
changes are small, rapid and occur equally 
across all the different points of the yield 
curve. In addition, effective duration is 
difficult to calculate precisely especially in 
the case of a bond that is callable prior to 
maturity.


the short-term rates paid to preferred shareholders. (The average rate paid on
the fund's preferred stock was 3.00% on March 15.) In the past, this has allowed
the fund to earn higher income than the monthly common stock dividend it paid
out and to build up a dividend reserve. However, as the difference between
short-term and long-term rates has narrowed, the additional income provided by
the preferred stock decreased.

MINNESOTA CONTINUES TO ENJOY A DIVERSE ECONOMY, WHICH LESSENS THE CONCERN OF
GEOGRAPHIC DIVERSIFICATION THAT MANY OTHER STATE-SPECIFIC FUNDS EXPERIENCE. No
single company or industry dominates in Minnesota; seven industries each account
for 8% to 20% of the state's economy. As a result, Minnesota usually has less
severe cycles of expansion and recession than most other states and even the
United States as a whole. The state's unemployment rate is typically lower than
the national average. Also, the credit quality of many Minnesota school district
issues has been raised by a program that allows school districts to apply for
state guarantees. This enables the school districts to receive the state's AA
credit rating and reduces the school districts' cost of borrowing.

OUR PROPRIETARY CREDIT ANALYSIS ON THE FUND'S HOLDINGS HAS HELPED THE FUND AVOID
ANY PAYMENT DEFAULTS. We continue to manage credit risk, or the risk of failure
of an issuer to make payment, through extensive due diligence and credit
analysis prior to purchasing bonds as well as while the bonds are held in the
portfolio. This research, which goes beyond the ratings given by Moody's or

S&P, helps ensure we maintain the quality of the portfolio. While we have not 
experienced any problems associated with payment defaults so far, this fund, 
and any fund investing in municipal securities, continues to have credit 
risk, and the failure of an issuer to make payments could result in a 
decrease in net asset value and a decrease in the income earned by the fund.

WE DON'T EXPECT TO MAKE ANY MAJOR CHANGES TO THE FUND IN THE NEXT FEW MONTHS. 
We believe the fund's current structure along with the current market 
environment should continue to provide municipal bond investors with 
attractive opportunities.

Thank you for investing in Minnesota Municipal Income Portfolio. We will 
continue to dedicate our efforts to helping you achieve your financial goals. 

Sincerely,

                           TAX REFORM PROPOSALS

Tossing out the current U.S. tax code and replacing it with a simpler tax 
system continues to be a hot issue among politicians in 1996. One proposal in 
particular - the flat tax - has been the most popular among congressional 
leaders and presidential candidates.

While there are many varying flat tax proposals, they all share some common 
elements of which municipal bond investors should be aware. Many flat tax 
proposals would only tax income from wages and salary and would exempt from 
tax the interest, dividends and capital gains earned on investments and real 
estate. Proponents of a flat tax argue that this would encourage more people 
to save money and would be good for investments. However, opponents of a flat 
tax say it would hurt tax-exempt municipal bond investors because municipal 
bonds currently have interest yields that are lower than taxable interest 
yields since the interest paid on municipal bonds is free from federal income 
tax. If all interest income were free of taxes, the advantage of investing in 
municipal securities would be eliminated and their prices would likely fall 
because municipal bonds pay lower interest yields than taxable bonds with 
similar maturities and credit quality. 

Most flat tax proposals would also do away with current deductions, 
exemptions and credits such as interest on home mortgage loans, charitable 
contributions, state and local taxes, and medical expenses. 

In spite of tax reform's increased popularity, many outspoken critics of a 
flat tax have emerged. These include Jerry Brown, the former governor of 
California, who was one of the first proponents of the flat tax. He stated 
that the flat tax by itself would not balance the budget, which is one 
benefit flat tax proponents are touting. The budget could only possibly be 
balanced with an additional wealth tax, Brown said.

Other critics agree that the flat tax proposal is unfair. The U.S. tax system 
has always been based on a graduated system, where those with more money pay 
more taxes because of their ability to do so. Homeowners and municipal bond 
investors and issuers, among others, have also begun to realize that they 
have too much to lose not to challenge this issue.

We anticipate that the flat tax debate will continue during 1996 but will 
subside after the November elections. In the meantime, we will continue to 
closely monitor this issue. We encourage you to keep an eye on the tax reform 
debate as well, but strongly suggest you continue to take advantage of the 
tax-free income that can be earned by investing in municipal bonds.

                         NOTES TO FINANCIAL STATEMENTS
 
(1) ORGANIZATION
                Minnesota Municipal Income Portfolio Inc. (the fund) is
                registered under the Investment Company Act of 1940 (as amended)
                as a non-diversified, closed-end management investment company.
                Shares of the fund are listed on the American Stock Exchange and
                the Chicago Stock Exchange. The fund will seek to achieve its
                investment objective by investing in Minnesota municipal
                obligations rated investment grade or of comparable quality when
                purchased.
(2) SIGNIFICANT
    ACCOUNTING
    POLICIES
                INVESTMENTS IN SECURITIES
                The values of fixed income securities are determined using
                pricing services or prices quoted by independent brokers. Open
                financial futures contracts are valued at the last settlement
                price. When market quotations are not readily available,
                securities are valued at fair value according to methods
                selected in good faith by the board of directors. Short-term
                securities with maturities of 60 days or less are valued at
                amortized cost which approximates market value.
 
                Securities transactions are accounted for on the date the
                securities are purchased or sold. Realized gains and losses are
                calculated on the identified-cost basis. Interest income,
                including amortization of bond discount and premium computed on
                a level-yield basis, is accrued daily.
 
                The fund concentrates its investments in Minnesota and,
                therefore, may have more credit risks related to the economic
                conditions of Minnesota than a portfolio with a broader
                geographical diversification.
 
                FUTURES TRANSACTIONS
                In order to gain exposure to or protect against changes in the
                market, the fund may buy and sell financial futures contracts
                and related options. Risks of entering into futures contracts
                and related options include the possibility there may be an
                illiquid market and that a change in the value of the contract
                or option may not correlate with changes in the value of the
                underlying securities.
 
                Upon entering into a futures contract, the fund is required to
                deposit either cash or securities in an amount (initial margin)
                equal to a certain percentage of the contract value. Subsequent
                payments (variation margin) are made or received by the fund
                each day. The variation margin payments are equal to the daily
                changes in the
 
                                       11

                         NOTES TO FINANCIAL STATEMENTS
                contract value and are recorded as unrealized gains and losses.
                The fund recognizes a realized gain or loss when the contract is
                closed
                or expires.
 
                SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
                Delivery and payment for securities that have been purchased by
                the fund on a forward-commitment or when-issued basis can take
                place a month or more after the transaction date. During this
                period, such securities do not earn interest, are subject to
                market fluctuations and may increase or decrease in value prior
                to their delivery. The fund maintains, in a segregated account
                with its custodian, assets with a market value equal to the
                amount of its purchase commitments. The purchase of securities
                on a when-issued or forward-commitment basis may increase the
                volatility of the fund's NAV to the extent the fund makes such
                purchases while remaining substantially fully invested. As of
                January 31, 1996, the fund had no outstanding when-issued or
                forward committments.
 
                FEDERAL TAXES
                The fund intends to comply with the requirements of the Internal
                Revenue Code applicable to regulated investment companies and to
                distribute all of its taxable income to shareholders. Therefore,
                no income tax provision is required. In addition, on a
                calendar-year basis, the fund will distribute substantially all
                of its taxable net investment income and realized gains, if any,
                to avoid payment of any federal excise taxes.
 
                Net investment income and net realized gains (losses) may differ
                for financial statement and tax purposes primarily because of
                market discount amortization and the deferral of "wash sale"
                transactions. The character of distributions made during the
                year from net investment income or net realized gains may also
                differ from their ultimate characterization for federal income
                tax purposes. In addition, due to the timing of dividend
                distributions, the fiscal year in which amounts are distributed
                may differ from the year that the income or realized gains
                (losses) were recorded by the fund.
 
                On the statement of assets and liabilities, as a result of
                permanent book-to-tax differences, reclassification adjustments
                have been made to decrease undistributed net investment income
                and accumulated net realized loss on investments by $3,288.

                         NOTES TO FINANCIAL STATEMENTS
 
                DISTRIBUTIONS TO SHAREHOLDERS
                Distributions from net investment income are made on a monthly
                basis for common shareholders and a weekly basis for preferred
                stock shareholders. Common stock distributions are recorded as
                of the close of business on the ex-dividend date, and preferred
                stock dividends are accrued daily. Realized capital gains, if
                any, will be distributed on an annual basis. Distributions are
                payable in cash or, for common shareholders, pursuant to the
                fund's dividend reinvestment plan, reinvested in additional
                shares of the fund's common stock. Under the plan, common shares
                will be purchased in the open market. Prior to amendment of this
                plan, effective November 23, 1994, the fund could issue new
                shares for reinvestment of distributions under certain
                circumstances.
 
                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 and disclosure of contingent assets
                and liabilities at the date of the financial statements and the
                reported results of operations during the reporting period.
                Actual results could differ from those estimates.
 
(3) REMARKETED
    PREFERRED STOCK
                The fund has issued and, as of January 31, 1996, has outstanding
                1,244 shares of remarketed preferred stock (622 shares in class
                "M" and 622 shares in class "W") ("RP-Registered Trademark-")
                with a liquidation preference of $25,000 per share. The dividend
                rate on the RP-Registered Trademark- is adjusted every seven
                days (on Mondays for class "M" and on Wednesdays for class "W")
                as determined by the remarketing agent. On January 31, 1996, the
                dividend rates were 3.28% and 3.30% for class "M" and "W",
                respectively.
 
(4) SECURITIES
    TRANSACTIONS
                Purchases of securities and proceeds from sales, other than
                temporary investments in short-term securities, for the year
                ended January 31, 1996, were $11,115,903 and $11,433,365,
                respectively.

(5) FEES AND
    EXPENSES
                The fund has entered into the following agreements with Piper
                Capital Management Incorporated (the adviser and administrator):
                The investment advisory agreement provides the adviser with a
                monthly investment management fee calculated at the annualized
                rate of 0.35% of the fund's average weekly net assets (computed
                by subtracting liabilities, which exclude preferred stock, from
                the value of the total assets of the fund). For its fee, the
                adviser will provide investment advice and, in general, conduct
                the management and investment activity of the fund.
 
                The administration agreement provides the administrator with a
                monthly fee in an amount equal to an annualized rate of 0.15% of
                the fund's average weekly net assets (computed by subtracting
                liabilities, which exclude preferred stock, from the value of
                the total assets of the fund). For its fee, the administrator
                will provide certain reporting, regulatory and record-keeping
                services for the fund.
 
                The fund has entered into a remarketing agent agreement with
                Merrill Lynch, Pierce, Fenner & Smith (the remarketing agent).
                The remarketing agreement provides the remarketing agent with a
                monthly fee in an amount equal to an annualized rate of 0.25% of
                the fund's average amount of RP-Registered Trademark-
                outstanding. For its fee, the remarketing agent will remarket
                shares of RP-Registered Trademark- tendered to it, on behalf of
                shareholders thereof, and will determine the applicable dividend
                rate for each seven-day dividend period.
 
                In addition to the advisory, administrative, and remarketing
                agent fees, the fund is responsible for paying most other
                operational expenses including outside directors' fees and
                expenses; custodian and registration fees; printing and
                shareholder reports; transfer agent fees and expenses; legal,
                auditing and accounting services; insurance, interest and other
                miscellaneous expenses.
 
(6) CAPITAL LOSS
    CARRYOVER
                For federal income tax purposes, the fund had a capital loss
                carryover of $3,107,759 as of January 31, 1996, which if not
                offset by subsequent capital gains, will expire in the years
                2002 through 2004. It is unlikely the board of directors will
                authorize a distribution of any net realized capital gains until
                the available capital loss carryover has been offset or expires.

(7) RETIREMENT OF
    FUND SHARES
                The fund's board of directors voted to discontinue the share
                repurchase program effective February 6, 1996. Under this
                program, repurchases could only be made when the previous day's
                closing market price was trading at a discount from net asset
                value. Daily repurchases were limited to 25% of the previous
                four weeks average daily trading volume on the American Stock
                Exchange. Under the plan, cumulative repurchases in the fund
                could not exceed 3% of the total shares originally issued.
                Pursuant to the plan, the fund had cumulatively repurchased and
                retired 19,500 shares as of January 13, 1996, which represents
                0.5% of the shares originally issued.

THE BOARD OF DIRECTORS AND SHAREHOLDERS

These financial statements and the financial highlights are the responsibility
of the fund's management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.
 
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 the 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. Investment securities held in custody are confirmed to us by the
custodian. 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 the financial highlights referred
to above present fairly, in all material respects, the financial position of
Minnesota Municipal Income Portfolio Inc. as of January 31, 1996, and the
results of its operations for the year then ended, the changes in its net assets

                            FEDERAL TAX INFORMATION
 
            Fiscal Year Ended January 31, 1996
 
            Federal tax information is presented as an aid to you in
            reporting distributions. Please consult a tax adviser on
            how to report these distributions at the state and local
            levels.
 
            SOURCE OF DISTRIBUTIONS
            During the year ended January 31, 1996, 100% of the
            fund's distributions were derived from interest on
            municipal securities and qualify as exempt-interest
            dividends for federal and state tax purposes.
 
            FEDERAL TAXATION
            Exempt-interest dividends are exempt from federal income
            taxes and should not be included in your gross income,
            but need to be reported on your income tax return for
            informational purposes.

SHARE REPURCHASE PROGRAM
Your fund's board of directors has voted to discontinue the share repurchase
program, effective February 6, 1996. The program had enabled the fund to 'buy
back' shares of its common stock in the open market.
 
TERMS AND CONDITIONS OF THE DIVIDEND REINVESTMENT PLAN
As a shareholder, you may choose to participate in your fund's Dividend
Reinvestment Plan. It is a convenient and economical way to buy additional
shares of the fund by automatically reinvesting dividends and capital gains. The
plan is administered by Investors Fiduciary Trust Company (IFTC), the plan
agent.
 
ELIGIBILITY/PARTICIPATION
You may join the plan at any time. Reinvestment of distributions will begin with
the next distribution paid, provided your enrollment card is received at least
10 days before the record date for that distribution.
 
If your shares are in certificate form, you may join the plan directly and have
your distributions reinvested in additional shares of the fund. To enroll in
this plan, call IFTC at 1-800-543-1627. If your shares are registered in your
brokerage firm's name or another name, ask the holder of your shares how you may
participate.
 
Banks, brokers or nominees, on behalf of their beneficial owners who wish to
reinvest dividend and capital gain distributions, may participate in the plan by
informing IFTC at least 10 days before each share's dividend and/or capital
gains distribution.
 
PLAN ADMINISTRATION
Beginning no more than five business days before the dividend payment date, IFTC
will buy shares of the fund on the American Stock Exchange or elsewhere on the
open market.
 
The fund will not issue any new shares in connection with the plan. All
reinvestments will be at a market price plus a pro rata share of any brokerage
commissions, which may be more or less than the fund's net asset value per
share. The number of shares allocated to you is determined by dividing the
amount of the dividend or distribution by the applicable price per share.
 
There is no direct charge for reinvestment of dividends and capital gains since
IFTC fees are paid by the fund. However, each participant pays a pro rata
portion of the brokerage commissions. Brokerage charges are expected to be lower
than those for

individual transactions because shares are purchased for all participants in
blocks. As long as you continue to participate in the plan, distributions paid
on the shares in your term trust account will be reinvested.
 
IFTC maintains accounts for plan participants holding shares in certificate
form. You will receive a monthly statement detailing total dividend and capital
gain distributions, date of investment, shares acquired, price per share, and
total shares held in your account, both certificate-form shares and unissued
shares acquired through the plan.
 
TAX INFORMATION
Distributions reinvested in additional shares of the fund are subject to income
tax, just as they would be if received in cash. In general, the tax basis of
such shares will equal the price paid by IFTC plus the pro rata share of any
commission. Each January, you will receive IRS Form 1099 regarding the federal
tax status of the prior year's distributions.
 
PLAN WITHDRAWAL
If you hold your shares in certificate form, you may terminate your
participation in the plan at any time by giving written notice to IFTC. If your
shares are registered in your brokerage firm's name, you may terminate your
participation via verbal or written instructions to your investment
professional. Written instructions should include your name and address as they
appear on the certificate or account.
 
If notice is received at least 10 days before the record date, all future
distributions will be paid directly to the shareholder of record.
 
If your shares are in certificate form and you discontinue your participation in
the plan, you (or your nominee) will receive an additional certificate for all
full shares and a check for any fractional shares in your account.
 
PLAN AMENDMENT/TERMINATION
The fund reserves the right to amend or terminate the plan. Should the plan be
terminated, participants will be notified in writing at least 90 days before the
record date for the next dividend or distribution. The plan may also be amended
or terminated by IFTC with at least 90 days' written notice to participants in
the plan.
 
Any questions about the plan should be directed to your investment professional
or to Investors Fiduciary Trust Company, P.O. Box 419432, Kansas City, Missouri
64141, 1-800-543-1627.

In an effort to reduce costs to our shareholders, we have
implemented a process to reduce duplicate mailings of
the fund's shareholder reports. This householding
process should allow us to mail one report to each
address where one or more registered shareholders with
the same last name reside. If you would like to have
additional reports mailed to your address, please call our
Shareholder Services area at 1 800 866-7778, or mail
