INVESTMENT POLICIES AND INVESTMENT PORTFOLIO
 
Investment Policies
 
  The investment objectives and certain fundamental investment policies of the
Fund are described in the Prospectus. The Fund, as a fundamental policy, may
not, without the approval of the holders of a majority of its shares:
 
    (1) With respect to 75% of its total assets, purchase the securities of
  any issuer (except securities issued or guaranteed by the United States
  government or any of its agencies or instrumentalities) if, as a result,
  (i) more than 5% of the Fund's total assets would be invested in securities
  of that issuer or (ii) the Fund would hold more than 10% of the outstanding
  voting securities of that issuer.
 
    (2) Borrow money, except that the Fund may (i) borrow money from banks
  for temporary or emergency purposes (but not for leverage or the purchase
  of investments) and (ii) engage in other transactions permissible under the
  Investment Company Act of 1940 that may involve a borrowing (such as
  obtaining such short-term credits as are necessary for the clearance of
  transactions, engaging in delayed-delivery transactions, or purchasing
  certain futures and options), provided that the combination of (i) and (ii)
  shall not exceed 33 1/3% of the value of the Fund's total assets (including
  the amount borrowed), less the Fund's liabilities (other than borrowings).
 
    (3) Act as an underwriter of another issuer's securities, except to the
  extent that the Fund may be deemed to be an underwriter within the meaning
  of the Securities Act of 1933 in connection with the purchase and sale of
  portfolio securities.
 
    (4) Make loans to other persons, except through (i) the purchase of debt
  securities permissible under the Fund's investment policies, (ii)
  repurchase agreements, or (iii) the lending of portfolio securities,
  provided that no such loan of portfolio securities may be made by the Fund
  if, as a result, the aggregate of such loans would exceed 33 1/3% of the
  value of the Fund's total assets.
 
    (5) Purchase or sell physical commodities unless acquired as a result of
  ownership of securities or other instruments (but this shall not prevent
  the Fund from purchasing or selling options, futures contracts, or other
  derivative instruments, or from investing in securities or other
  instruments backed by physical commodities).
 
    (6) Purchase or sell real estate unless acquired as a result of ownership
  of securities or other instruments (but this shall not prohibit the Fund
  from purchasing or selling securities or other instruments backed by real
  estate or of issuers engaged in real estate activities).
 
                                      S-2
<PAGE>
 
    (7) Issue senior securities, except as permitted under the Investment
  Company Act of 1940.
 
    (8) Purchase the securities of any issuer if, as a result, 25% or more of
  the Fund's total assets would be invested in the securities of issuers
  whose principal business activities are in the same industry (except that
  this restriction shall not be applicable to securities issued or guaranteed
  by the U.S. government or any of its agencies or instrumentalities).
  Electric company securities, natural gas company securities, and
  telecommunications company securities shall each be considered securities
  of issuers in separate industries for the purpose of this restriction.
 
  Except for restriction (2), if a percentage restriction is adhered to at the
time of investment, a later increase in percentage resulting from a change in
market value of the investment or the total assets will not constitute a
violation of that restriction.
 
  The foregoing fundamental policies, together with the investment objective of
the Fund, cannot be changed without approval by holders of a "majority of the
Fund's outstanding voting shares." As defined in the Investment Company Act of
1940, this means the vote of (i) 67% or more of the Fund's shares present at a
meeting, if the holders of more than 50% of the Fund's shares are present or
represented by proxy or (ii) more than 50% of the Fund's shares, whichever is
less.
 
  In addition to the fundamental investment policies listed above, the Fund is
also subject to the following non-fundamental restrictions and policies, which
may be changed by the Board of Directors without shareholder approval.
 
  The Fund may not:
 
    (1) Sell securities short, unless the Fund owns or has the right to
  obtain securities equivalent in kind and amount to the securities sold at
  no added cost, and provided that transactions in options, futures
  contracts, options on futures contracts, or other derivative instruments
  are not deemed to constitute selling securities short.
 
    (2) Purchase securities of open-end or closed-end investment companies
  except in compliance with the Investment Company Act of 1940 or any
  exemptive relief obtained thereunder.
 
    (3) Enter into futures contracts or related options or forward contracts,
  if more than 30% of the Fund's net assets would be represented by futures
  contracts or more than 5% of the Fund's net assets would be committed to
  initial margin deposits and premiums on futures contracts and related
  options.
 
    (4) Purchase securities when borrowings exceed 5% of its total assets. If
  due to market fluctuations or other reasons, the value of the Fund's assets
  falls below 300% of its borrowings, the Fund will reduce its borrowings
  within 3 business days. To do this, the Fund may have to sell a portion of
  its investments at a time when it may be disadvantageous to do so.
 
    (5) Invest in illiquid securities if, as a result of such investment,
  more than 15% of the Fund's net assets would be invested in illiquid
  securities.
 
    (6) Purchase securities of companies for the purpose of exercising
  control.

INVESTMENT POLICIES AND TECHNIQUES
 
  The following information supplements, and should be read in conjunction
with, the discussion of the Fund's investment objectives, policies and
techniques that are described in the Prospectus.
 
Investments in Fixed-Income Securities
 
  As described in the Prospectus, the Fund invests a majority of its assets
primarily in fixed-income securities of varying maturities. At least 65% of the
Fund's assets in fixed-income securities are investment grade quality.
Investment grade quality securities are securities which are rated at the time
of purchase within the four highest grades (Baa or BBB or better) by Moody's
Investors Service, Inc. ("Moody's"), by Standard and Poor's Corporation
("S&P"), by Fitch Investors Service, Inc. ("Fitch"), or by Duff & Phelps Inc.
("D&P") or are unrated fixed-income securities which, in the opinion of Nuveen
Advisory Corp. ("NAC"), are of comparable quality to bonds rated within the
four highest grades by Moody's, S&P, Fitch, or D&P. The Fund may also invest up
to 20% of its bonds in dollar-denominated securities of foreign issuers whose
headquarters are located in a country that is a member of the Organization for
Economic Cooperation and Development.
 
  The Fund may invest up to 35% of its net assets in a combination of (a)
fixed-income securities that are not investment grade quality, or (b) fixed
maturity preferred stock. Securities rated below investment grade are commonly
known as "high-yield," "high risk" or "junk" bonds which typically offer higher
yields but involve greater risks, including the possibility of default or
bankruptcy, and increased market volatility. The Fund limits its below-
investment grade quality to those that are either rated BB/Ba or B by at least
one of the national rating agencies or are unrated but judged to be comparable
in quality by NAC. Lastly, the Fund may invest in temporary investments as
described below. See Appendix A for more information about ratings by Moody's,
S&P, Fitch and D&P.
 
  NAC looks for bonds that appear especially attractive on a relative value
basis, and concentrate on those with intermediate-term characteristics that we
believe offer the best balance of current income and capital preservation
potential. Securities that are undervalued or that represent undervalued market
sectors are securities that, in NAC's opinion, are worth more than the value
assigned to them in the marketplace. Securities of particular types or purposes
may be undervalued because there is a temporary excess of supply in that market
sector, or because of a general decline in the market price of securities in
the market sector for reasons that do not apply to the particular securities
that are considered undervalued. The Fund's investment in undervalued
securities will be based on NAC's belief that their prices should ultimately
reflect their true value. In seeking undervalued securities, the Fund may
purchase underrated securities. Underrated securities are those whose ratings
do not, in NAC's opinion, reflect their true value. Such securities may be
underrated because of the time that has elapsed since their rating was assigned
or reviewed, or because of positive factors that may not have been fully taken
into account by rating agencies, or for other similar reasons.
 
  Fixed-income securities include securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government securities");
foreign government bonds; corporate debt securities (other than convertible
bonds); and corporate commercial paper; preferred stocks with stated
maturities; mortgage-backed and other asset-backed securities; inflation-
indexed bonds issued by both governments and corporations; structured notes,
including hybrid or "indexed" securities, and loan participations; delayed
funding loans and revolving credit facilities; bank certificates of deposit,
fixed time deposits and bankers' acceptances; repurchase agreements and reverse
repurchase agreements; debt securities issued by states or local governments
and their agencies, authorities and other instrumentalities; obligations of
foreign governments or their subdivisions, agencies and instrumentalities;
obligations of international agencies or supranational entities; and similar
instruments. Fixed income securities may have fixed, variable, or floating
rates of interest including rates of interest that vary inversely at a multiple
of a designated or floating rate, or that vary according to changes in relative
values of currencies. The Fund may invest all of its assets in derivative
instruments or in mortgage- or
 
                                      S-4
<PAGE>
 
asset-backed securities. The Fund may adhere to its investment policy by
entering into a series of purchase and sale contracts or utilizing other
investment techniques by which it may obtain market exposure to the securities
in which it primarily invests. Some of the fixed income securities in which the
Fund may invest are described in further detail below.
 
  Loans Participations. The Fund may invest in loan participations, which may
have speculative characteristics, when the investment adviser believes such
investments offer the possibility of long-term appreciation in value. Loan
participations are interests in floating or variable rate senior loans to U.S.
corporations, partnerships, and other entities that operate in a variety of
industries and geographic regions. An investment in loan participations carries
a high degree of risk and may have the consequence that interest payments with
respect to such securities may be reduced, deferred, suspended, or eliminated
and may have the further consequence that principal payments may likewise to
reduced, deferred, suspended or canceled, causing the loss of the entire amount
of the investment. In addition, most loan participations are illiquid. To the
extent that loan participations are deemed to be illiquid, they will be subject
to the Fund's 15% restriction on investments in illiquid securities.
 
  Loans in which the Fund will purchase participation interests may pay
interest at rates which are periodically redetermined on the basis of a base
lending rate plus a premium. These base lending rates are generally the Prime
Rate offered by a major U.S. bank, the London Inter-Bank Offered Rate, the
Certificate of Deposit rate or other base lending rates used by commercial
lenders. The loans typically have the most senior position in a borrower's
capital structure, although some loans may hold an equal ranking with other
senior securities of the borrower. Although the loans generally are secured by
specific collateral, the Fund may invest in loans which are not secured by any
collateral. Uncollateralized loans pose a greater risk of nonpayment of
interest or loss of principal than do collateralized loans. The collateral
underlying a collateralized loan may consist of assets that may not be readily
liquidated, and there is no assurance that the liquidation of such assets would
satisfy fully a borrower's obligation under a loan. The Fund is not subject to
any restrictions with respect to the maturity of the loans in which it
purchases participation interests.
 
  The loans in which the Fund will purchase participation interests generally
are not rated by nationally recognized statistical rating organizations.
Ratings of other securities issued by a borrower do not necessarily reflect
adequately the relative quality of a borrower's loans. Therefore, although the
investment adviser may consider such ratings in determining whether to invest
in a particular loan, such ratings will not be the determinative factor in the
investment adviser's analysis.
 
  The loans are not readily marketable and may be subject to restrictions on
resale. Participation interests in the loans generally are not listed on any
national securities exchange or automated quotation system and no regular
market has developed for such interests. Any secondary purchases and sales of
loan participations generally are conducted in private transactions between
buyers and sellers. Many of the loans in which the Fund expects to purchase
interests are of a relatively large principal amount and are held by a
relatively large number of owners which, in the investment adviser's opinion,
should enhance the relative liquidity of such interests.
 
  When acquiring a loan participation, the Fund will have a contractual
relationship only with the lender (typically an entity in the banking, finance
or financial services industries), not with the borrower. The Fund has the
right to receive payments of principal and interest to which it is entitled
only from the lender selling the loan participation and only upon receipt by
such lender of such payments from the borrower. In connection with purchasing
loan participations, the Fund generally will have no right to enforce
compliance by the borrower with the terms of the loan agreement, nor any rights
with respect to any funds acquired by other lenders through set-off against the
borrower, and the Fund may not directly benefit from the collateral supporting
the loan in which it has purchased the loan participation. As a result, the
Fund may assume the credit risk of both the borrower and the lender selling the
loan participation. In the event of insolvency of the lender selling a loan
participation, the Fund may be treated as a general creditor of such lender,
and may not benefit from any set-off between such lender and the borrower.

  Non-Investment Grade Debt Securities ("Junk Bonds"). The Fund may invest in
junk bonds. Junk bonds, while generally offering higher yields than investment
grade securities with similar maturities, involve greater risks, including the
possibility of default or bankruptcy. They are regarded as predominantly
speculative with respect to the issuer's capacity to pay interest and repay
principal. The special risk considerations in connection with investments in
these securities are discussed below. Refer to Appendix A of this Statement of
Additional Information for a discussion of securities ratings.
 
    (1) Effect of Interest Rates and Economic Changes. The junk bond market
  is relatively new and its growth has paralleled a long economic expansion.
  As a result, it is not clear how this market may withstand a prolonged
  recession or economic downturn. Such an economic downturn could severely
  disrupt the market for and adversely affect the value of such securities.
 
    All interest-bearing securities typically experience appreciation when
  interest rates decline and depreciation when interest rates rise. In
  addition, the market values of junk bond securities tend to reflect
  individual corporate developments to a greater extent than do the market
  values of higher rated securities, which react primarily to fluctuations in
  the general level of interest rates. Junk bond securities also tend to be
  more sensitive to economic conditions than are higher rated securities. As
  a result, they generally involve more credit risk than securities in the
  higher rated categories. During an economic downturn or a sustained period
  of rising interest rates, highly leveraged issuers of junk bond securities
  may experience financial stress and may not have sufficient revenues to
  meet their payment obligations. The risk of loss due to default by an
  issuer of these securities is significantly greater then by an issuer of
  higher rated securities because such securities are generally unsecured and
  are often subordinated to other creditors. Further, if the issuer of a junk
  bond security defaults, the Fund may incur additional expenses to seek
  recovery. Periods of economic uncertainty and changes would also generally
  result in increased volatility in the market prices of these and thus in
  the Fund's net asset value.
 
    As previously stated, the value of a junk bond security will generally
  decrease in a rising interest rate market and, accordingly, so will the
  Fund's net asset value. If the Fund experiences unexpected net redemptions
  in such a market, it may be forced to liquidate a portion of its portfolio
  securities without regard to their investment merits. Due to the limited
  liquidity of junk bond securities, the Fund may be forced to liquidate
  these securities at a substantial discount. Any such liquidation would
  reduce the Fund's asset base over which expenses could be allocated and
  could result in a reduced rate of return for the Fund.
 
    (2) Payment Expectations. Junk bond securities typically contain
  redemption, call, or prepayment provisions that permit the issuer of
  securities containing such provisions to redeem the securities at its
  discretion. During periods of falling interest rates, issuers of these
  securities are likely to redeem or prepay the securities and refinance them
  with debt securities with a lower interest rate. To the extent an issuer is
  able to refinance the securities, or otherwise redeem them, the Fund may
  have to replace the securities with a lower yielding securities, which
  could result in a lower return for the Fund.
 
    (3) Credit Ratings. Credit ratings are issued by credit rating agencies
  and are indicative of the rated securities' safety of principal and
  interest payments. They do not, however, evaluate the market value risk of
  junk bond securities and, therefore, may not fully reflect the true risks
  of such an investment. In addition, credit rating agencies may not make
  timely changes in a rating to reflect changes in the economy or in the
  condition of the issuer that affect the value of the security.
  Consequently, credit ratings are used only as a preliminary indicator of
  investment quality. Investments in junk bonds will depend more upon credit
  analysis by NAC than investments in investment grade debt securities. NAC
  employs its own credit research and analysis, which includes a study of the
  issuer's existing debt, capital structure, ability to service debts pay
  dividends, sensitivity to economic conditions, operating history, and
  current earnings trend. NAC
 
                                      S-6
<PAGE>
 
  continually monitors the Fund's investments and carefully evaluates whether
  to dispose of or to retain junk bond securities whose credit ratings or
  credit quality may have changed.
 
    (4) Liquidity and Valuation. The Fund may have difficulty disposing of
  certain junk bond securities because there may be a thin trading market for
  such securities. Not all dealers maintain markets in all junk bond
  securities. As a result, there is no established retail secondary market
  for many of these securities. The Fund anticipates that such securities
  could be sold only to a limited number of dealers or institutional
  investors. To the extent a secondary trading market does exist, it is
  generally not as liquid as the secondary market for higher rated
  securities. The lack of a liquid secondary market may have an adverse
  impact on the market price of the security. The lack of a liquid secondary
  market for certain securities may also make it more difficult for the Fund
  to obtain accurate market quotations for purposes of valuing its
  securities. Market quotations are generally available on many junk bond
  issues only from a limited number of dealers and may not necessarily
  represent firm bids of such dealers or prices for actual sales. During
  periods of thin trading, the spread between bid and asked prices is likely
  to increase significantly. In addition, adverse publicity and investor
  perceptions, whether or not based on fundamental analysis, may decrease the
  value and liquidity of junk bond securities, especially in a thinly traded
  market.
 
  Pass-Through Securities. The Fund may invest in various fixed-income
obligations backed by a pool of mortgages or other assets. The pass-through
securities in which the Fund may invest are each described below.
 
    (1) "Mortgage-backed securities" are issued both by U.S. government
  agencies, including the Government National Mortgage Association (GNMA),
  the Federal National Mortgage Association (FNMA), and the Federal Home Loan
  Mortgage Corporation (FHLMC), and by private entities. The payment of
  interest and principal on securities issued by U.S. government agencies is
  guaranteed by the full faith and credit of the U.S. government (in the case
  of GNMA securities) or the issuer (in the case of FNMA and FHLMC
  securities). However, the guarantees do not apply to the market prices and
  yields of these securities, which vary with changes in interest rates.
  Mortgage-backed securities issued by private entities are structured
  similarly to mortgage-backed securities issued by GNMA, FNMA, and FHLMC.
  These securities and the underlying mortgages are not guaranteed by
  government agencies. However, these securities generally are structured
  with one or more types of credit enhancement by a third party. Mortgage-
  backed securities permit borrowers to prepay their underlying mortgages.
  Prepayments by borrowers on underlying obligations can alter the effective
  maturity of these instruments.
 
    (2) "Collateralized mortgage obligations" (CMOs) are also backed by a
  pool of mortgages or mortgage loans, which are divided into two or more
  separate bond issues. CMOs issued by U.S. government agencies are backed by
  agency mortgages, while privately issued CMOs may be backed by either
  government agency mortgages or private mortgages. Payments of principal and
  interest are passed through to each bond at varying schedules resulting in
  bonds with different coupons, effective maturities, and sensitivities to
  interest rates. In fact, some CMOs may be structured in a way that when
  interest rates change the impact of changing prepayment rates on these
  securities' effective maturities is magnified.
 
    (3) "Commercial mortgage-backed securities" are backed by mortgages of
  commercial property, such as hotels, office buildings, retail stores,
  hospitals, and other commercial buildings. These securities may have a
  lower prepayment risk than other mortgage-related securities because
  commercial mortgage loans generally prohibit or impose penalties on
  prepayments of principal. In addition, commercial mortgage-related
  securities often are structured with some form of credit enhancement or
  protect against potential losses on the underlying mortgage loans. Many of
  the risks of investing in commercial mortgage-backed securities reflect the
  risks of investing in the real estate securing the underlying mortgage
  loans, including the effects of local and other economic conditions on real
  estate markets, the ability of tenants to make loan payments, and the
  ability of a property to attract and retain tenants.
 
                                      S-7
<PAGE>
 
    (4) "Asset-backed securities" are backed by other assets such as credit
  card, automobile or consumer loan receivables, retail installment loans, or
  participations in pools of leases. Credit support for these securities may
  be based on the underlying assets and/or provided through credit
  enhancement by a third party. The values of these securities are sensitive
  to changes in the credit quality of the underlying collateral. The credit
  strength of the credit enhancement, changes in interest rates, and at times
  the financial condition of the issuer. Some asset-backed securities also
  may receive prepayments, which can change the securities' effective
  maturities.
 
    (5) Other Mortgage-Related Securities. The Fund may invest in real estate
  investment conduits which are issued in portions or tranches with varying
  maturities and characteristics. Some tranches may only receive the interest
  paid on the underlying mortgages (IOs) and others may only receive the
  principal payments (POs). The values of IOs and POs are extremely sensitive
  to interest rate fluctuations and prepayment rates, and IOs are also
  subject to the risk of early repayment of the underlying mortgages, which
  will substantially reduce or eliminate interest payments. To the extent
  that the Fund invests in IOs and POs, its does not intend to invest more
  than 5% of its assets in such securities.
 
  Inflation-Indexed Bonds. The Fund may invest in inflation-indexed bonds
issued by the U.S. Government, its agencies or instrumentalities, or by private
corporations. The principal value of this type of bond is periodically adjusted
according to changes in the rate of inflation. The interest rate is generally
fixed at issuance; however, interest payments are based upon an inflation
adjusted principal value. For example, in a period of falling inflation,
principal value will be adjusted downward, reducing the interest payable.
 
  Repayment of the original bond principal upon maturity (as adjusted for
inflation) is guaranteed in the case of U.S. Treasury inflation indexed bonds,
even during a period of deflation. However, the current market value of the
bonds is not guaranteed and will fluctuate. The Fund may also invest in other
bonds which may or may not provide a similar guarantee. If a guarantee of
principal is not provided, the adjusted principal value of the bond repaid at
maturity may be less than the original principal.
 
  Other Considerations. Obligations of issuers are subject to the provisions of
bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Bankruptcy Reform Act of 1978. In addition, the
obligations of such issuers may become subject to the laws enacted in the
future by Congress, state legislatures or referenda extending the time for
payment of principal or interest, or both, or imposing other constraints upon
enforcement of such obligations or upon municipalities to levy taxes. There is
also the possibility that, as a result of legislation or other conditions, the
power or ability or any issuer to pay, when due, the principal of an interest
on its securities may be materially affected.
 
  During temporary defensive periods (e.g., times when, in NAC's opinion, the
ability of the Fund to meet its long-term investment objectives and preserve
the asset value of the Fund may be adversely affected by significant adverse
market, economic, political, or other circumstances), and in order to keep cash
on hand fully invested, the Fund may invest any percentage of its assets in
temporary investments. For further information, see "Short-Term Investments"
below.
 
Equity Securities
 
  Under normal market conditions, the Fund invests at least 25% of its assets
in equity securities of mid- and large-cap companies with market
capitalizations of at least $1 billion ("Equity Securities"). Equity Securities
include, but are not limited to, common stocks, preferred stocks having no
stated maturity, warrants to purchase common stocks or preferred stocks,
securities convertible into common or preferred stocks, such as convertible
bonds and debentures, and other securities with equity characteristics.
 
                                      S-8
<PAGE>
 
  In addition, the Fund may invest up to 20% of its equity allocation in
dollar-denominated equity securities of foreign issuers, including American
Depository Receipts ("ADRs") as described in "Foreign Securities" below.
 
  Convertible Bonds. A convertible debt security is a bond, debenture, note, or
other security that entitles the holder to acquire common stock or other equity
securities of the same or a different issuer. A convertible security generally
entitles the holder to receive interest paid or accrued until the convertible
security matures or is redeemed, converted or exchanged. Before conversion,
convertible securities have characteristics similar to non-convertible debt
securities. Convertible securities rank senior to common stock in a
corporation's capital structure and, therefore, generally entail less risk than
the corporation's common stock, although the extent to which such risk is
reduced depends in large measure upon the degree to which the convertible
security sells above its value as a fixed income security.
 
  A convertible security may be subject to redemption at the option of the
issuer at a predetermined price. If a convertible security held by the Fund is
called for redemption, the Fund would be required to permit the issuer to
redeem the security and convert it to underlying common stock, or would sell
the convertible security to a third party. The convertible securities in which
the Fund may invest must be rated at least BBB by S&P, D&P, or Fitch, or at
least Baa by Moody's.
 
  Eurodollar Convertibles. The Fund may invest in eurodollar convertibles.
Eurodollar convertibles are fixed-income securities of a foreign issuer that
are issued in U.S. dollars outside the U.S. and are convertible into or
exchangeable for specified equity securities.
 
Cash Equivalents and Short-Term Instruments
 
  Short-Term Fixed Income Securities. The Fund may invest up to 20% of its
assets in cash equivalents and short-term fixed-income securities under normal
market conditions, or to keep cash on hand fully invested. In addition, for
temporary defensive purposes, the Fund may invest up to 100% of its total
assets in such instruments. Short-term fixed-income securities are defined to
include, without limitation, the following:
 
    (1) U.S. government securities, including bills, notes and bonds
  differing as to maturity and rates of interest that are either issued or
  guaranteed by the U.S. Treasury or by U.S. government agencies or
  instrumentalities. U.S. government agency securities include securities
  issued by (a) the Federal Housing Administration, Farmers Home
  Administration, Export-Import Bank of the United States, Small Business
  Administration, and the Government National Mortgage Association, whose
  securities are supported by the full faith and credit of the United States;
  (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the
  Tennessee Valley Authority, whose securities are supported by the right of
  the agency to borrow from the U.S. Treasury; (c) the Federal National
  Mortgage Association, whose securities are supported by the discretionary
  authority of the U.S. government to purchase certain obligations of the
  agency or instrumentality; and (d) the Student Loan Marketing Association,
  whose securities are supported only by its credit. While the U.S.
  government provides financial support to such U.S. government-sponsored
  agencies or instrumentalities, no assurance can be given that it always
  will do so since it is not so obligated by law. The U.S. government, its
  agencies, and instrumentalities do not guarantee the market value of their
  securities. Consequently, the value of such securities may fluctuate. In
  addition, the Fund may invest in sovereign debt obligations of foreign
  countries. A sovereign debtor's willingness or ability to repay principal
  and interest in a timely manner may be affected by a number of factors,
  including its cash flow situation, the extent of its foreign reserves, the
  availability of sufficient foreign exchange on the date a payment is due,
  the relative size of the debt service burden to the economy as a whole, the
  sovereign debtor's policy toward principal international lenders and the
  political constraints to which it may be subject.

    (2) Certificates of Deposit issued against funds deposited in a bank or a
  savings and loan association. Such certificates are for a definite period
  of time, earn a specified rate of return, and are normally negotiable. If
  such certificates of deposit are non-negotiable, they will be considered
  illiquid securities and be subject to the Fund's applicable restriction on
  investment in illiquid securities. The issuer of a certificate of deposit
  agrees to pay the amount deposited plus interest to the bearer of the
  certificate on the dated specified thereon. Under current FDIC regulations,
  the maximum insurance payable as to any one certificate of deposit is
  $100,000; therefore, certificates of deposit purchased by the Fund may not
  be fully insured.
 
    (3) Bankers' acceptances, which are short-term credit instruments used to
  finance commercial transactions. Generally, an acceptance is a time draft
  drawn on a bank by an exporter or an importer to obtain a stated amount of
  funds to pay for specific merchandise. The draft is then "accepted" by a
  bank that, in effect, unconditionally guarantees to pay the face value of
  the instrument on its maturity date. The acceptance may then be held by the
  accepting bank as an asset or it may be sold in the secondary market at the
  going rate of interest for a specific maturity.
 
    (4) Repurchase agreements, which involve purchases of debt securities. At
  the time the Fund purchases securities pursuant to a repurchase agreement,
  it simultaneously agrees to resell and redeliver such securities to the
  seller, who also simultaneously agrees to buy back the securities at a
  fixed price and time. This assures a predetermined yield for the Fund
  during its holding period, since the resale price is always greater than
  the purchase price and reflects an agreed-upon market rate. Such actions
  afford an opportunity for the Fund to invest temporarily available cash.
  The Fund may enter into repurchase agreements only with respect to
  obligations of the U.S. government, its agencies or instrumentalities;
  certificates of deposit; or bankers' acceptances in which the Fund may
  invest. Repurchase agreements may be considered loans to the seller,
  collateralized by the underlying securities. The risk to the Fund is
  limited to the ability of the seller to pay the agreed-upon sum on the
  repurchase date; in the event of default, the repurchase agreement provides
  that the Fund is entitled to sell the underlying collateral. If the value
  of the collateral declines after the agreement is entered into, and if the
  seller defaults under a repurchase agreement when the value of the
  underlying collateral is less than the repurchase price, the Fund could
  incur a loss of both principal and interest. The investment adviser
  monitors the value of the collateral at the time the action is entered into
  and at all times during the term of the repurchase agreement. The
  investment adviser does so in an effort to determine that the value of the
  collateral always equals or exceeds the agreed-upon repurchase price to be
  paid to the Fund. If the seller were to be subject to a federal bankruptcy
  proceeding, the ability of the Fund to liquidate the collateral could be
  delayed or impaired because of certain provisions of the bankruptcy laws.
 
    (5) Bank time deposits, which are monies kept on deposit with banks or
  savings and loan associations for a stated period of time at a fixed rate
  of interest. There may be penalties for the early withdrawal of such time
  deposits, in which case the yields of these investments will be reduced.
 
    (6) Commercial paper, which consists of short-term unsecured promissory
  notes, including variable rate master demand notes issued by corporations
  to finance their current operations. Master demand notes are direct lending
  arrangements between the Fund and a corporation. There is no secondary
  market for such notes. However, they are redeemable by the Fund at any
  time. The investment adviser will consider the financial condition of the
  corporation (e.g., earning power, cash flow, and other liquidity ratios)
  and will continuously monitor the corporation's ability to meet all of its
  financial obligations, because the Fund's liquidity might be impaired if
  the corporation were unable to pay principal and interest on demand.
  Investments in commercial paper will be limited to commercial paper rated
  in the two highest categories by a major rating agency or unrated
  commercial paper which is, in the opinion of the investment adviser, of
  comparable quality.

Duration and Portfolio Maturity
 
  In administering the Fund's investments, NAC currently intends that the
average portfolio duration of the Fund will normally vary within a three- to
six-year time frame based upon NAC's forecast for interest rates. Duration is
an indicator of the expected volatility of a bond position in response to
changes in interest rates. In calculating duration, the Fund measures the
average time required to receive all cash flows associated with those debt
securities representing payments of principal and interest by considering the
timing, frequency and amount of payment expected from each portfolio debt
security. The higher the duration, the greater the gains and losses when
interest rates change. Duration generally is a more accurate measure of
potential volatility with a portfolio composed of high-quality debt securities,
such as U.S. Government securities, municipal securities and high-grade U.S.
corporate bonds, than with lower-grade securities.
 
  NAC may use several methods to manage the duration of the Fund's bond
position in order to increase or decrease its exposure to changes in interest
rates. First, NAC may adjust duration by adjusting the mix of debt securities
held by the Fund. For example, if NAC intends to shorten duration, it may sell
debt instruments that individually have a long duration and purchase other debt
instruments that individually have a shorter duration. Among the factors that
will affect a debt security's duration are the length of time to maturity, the
timing of interest and principal payments, and whether the terms of the
security give the issuer of the security the right to call the security prior
to maturity. Second, NAC may adjust bond duration using derivative
transactions, especially with interest rate futures and options contracts. For
example, if NAC wants to lengthen the duration of the Fund's bond position, it
could purchase interest rate futures contracts instead of buying longer-term
bonds or selling shorter-term bonds. Similarly, during periods of lower
interest rate volatility, NAC may use a technique to extend duration in the
event rates rise by writing an out-of-the-money put option and receiving
premium income with the expectation that the option could be exercised. In
managing duration, the use of such derivatives may be faster and more efficient
than trading portfolio securities.
 
  Weighted average effective maturity is another indicator of potential
volatility used by NAC with respect to the Fund's bond portfolio, although for
certain types of debt securities, such as high quality debt securities, it is
not as accurate as duration in quantifying potential volatility. Weighted
average effective maturity is the average of all maturities of the individual
debt securities held by the Fund, weighted by the market value of each
security. Generally, the longer the weighted average effective maturity, the
more bond prices will vary in response to changes in interest rates.
 
  The Fund buys bonds with different maturities in pursuit of its investment
objective, but maintains under normal market conditions a bond portfolio with
an overall weighted average effective maturity of 5 to 10 years. Preferred
stocks with fixed maturities, which are classified as fixed-income securities
for asset allocation purposes as previously described, are not treated as bonds
for purposes of the average effective maturity limits. These preferred stocks
are generally expected to constitute a substantial portion of the fund's fixed-
income allocation. A bond's effective maturity may be significantly shorter
than its stated maturity due to certain features (such as puts, an adjustable
coupon, or a prepayment schedule or expected prepayment rate, but not a call
provision) that cause the bond to experience the same price volatility as a
shorter-maturity but otherwise comparable bond. For example, a mortgage-backed
security with a 30-year stated maturity but structured to have an expected
maturity of 7 years will generally experience price changes due to market
interest rate movements similar to an ordinary bond with a 7-year maturity.
Consequently, the Fund portfolio's average stated maturity could be
significantly longer than 10 years but, because its average effective maturity
will be less than 10 years, Fund shares should under normal market conditions
experience price volatility similar to an ordinary bond with a stated maturity
of less than 10 years. Is it possible that, if market interest rates were to
rise rapidly and substantially, the Fund will experience somewhat more
volatility than a bond with a stated maturity of less than 10 years.
 
                                      S-11
<PAGE>
 
  The policy of having a weighted average portfolio effective maturity of 5 to
10 years will not limit the effective maturity of any particular bond, and one
or more portfolio bonds may have effective maturities less than 5 years or
greater than 10 years so long as the weighted average effective maturity
remains between 5 and 10 years.
 
  The average effective maturity policy will apply at all times, even though
changes to the average effective maturity may result from market changes
independent of any portfolio changes. For example, if the average effective
maturity rises above 10 years not because of portfolio changes but rather
because market changes have lengthened the effective maturities of certain
bonds in the portfolio, the adviser will promptly adjust the portfolio to bring
the average below 10 years. The average effective maturity may occasionally
fall below 5 years during a temporary defensive period in response to adverse
market conditions, or because cash on hand awaiting investment in long-term
bonds is invested in short-term securities which tend to lower the portfolio's
overall average effective maturity.
 
Hedging Strategies
 
  General Description of Hedging Strategies. The Fund may engage in hedging
activities. NAC may cause the Fund to utilize a variety of financial
instruments, including options, futures contracts (sometimes referred to as
"futures"), forward contracts, and options on futures contracts to attempt to
hedge the Fund's holdings.
 
  Hedging or derivative instruments on securities generally are used to hedge
against price movements in one or more particular securities positions that the
Fund owns or intends to acquire. Such instruments may also be used to "lock-in"
realized but unrecognized gains in the value of portfolio securities. Hedging
strategies, if successful, can reduce the risk of loss by wholly and partially
offsetting the negative effect of unfavorable price movements in the
investments being hedged. However, hedging strategies can also reduce the
opportunity for gain by offsetting the positive effect of favorable price
movements in the hedged investments. The Fund may also use derivative
instruments to manage the risks of its assets. Risk management strategies
include, but are not limited to, facilitating the sale of Fund securities,
managing the effective maturity or duration of debt obligations that the Fund
holds, establishing a position in the derivatives markets as a substitute for
buying or selling certain securities or creating or alerting exposure to
certain asset classes, such as debt and foreign securities. The use of
derivative instruments may provide a less expensive, more expedient, or more
specifically focused way for the Fund to invest than would "traditional"
securities (i.e., stocks or bonds). The use of hedging instruments is subject
to applicable regulations of the Securities and Exchange Commission (the
"SEC"), the several options and futures exchanges upon which they are traded,
the Commodity Futures Trading Commission (the "CFTC") and various state
regulatory authorities. In addition, the Fund's ability to use hedging
instruments will be limited by tax considerations.
 
  General Limitation on Futures and Options Transactions. The Corporation has
filed a notice of eligibility for exclusion from the definition of the term
"commodity pool operator" with the CFTC and the National Futures Association,
which regulate trading in the futures markets. In accordance with Rule 4.5 of
the regulations under the Commodities Exchange Act (the "CEA"), the notice of
eligibility for the Fund includes a representation that the Fund will use
futures contracts and related options solely for "bona fide hedging" purposes
within the meaning of CFTC regulations. The Fund may, however, hold other
positions in futures contracts and related options that do not qualify as a
bona fide hedging position if the aggregate initial margin deposits and
premiums required to establish these positions, less the amount by which any
such futures contracts and related options positions are "in the money," do not
exceed 5% of the Fund's net assets. Adherence to these guidelines does not
limit the Fund's risk to 5% of its assets. In addition to the foregoing
guidelines, the Fund may not enter into options, futures, or options on futures
transactions if more than 30% of its net assets would be committed to such
instruments.
 
  The foregoing limitations are not fundamental policies of the Fund and may be
changed without shareholder approval as regulatory agencies permit. Various
exchanges and regulatory authorities have undertaken
 
                                      S-12
<PAGE>
 
reviews of options and futures trading in light of market volatility. Among the
possible actions that have been presented are proposals to adopt new or more
stringent daily price fluctuation limits for futures and options transactions
and proposals to increase the margin requirements for various types of futures
transactions.
 
  Asset Coverage for Futures and Options Positions. The Fund will comply with
the regulatory requirements of the SEC and the CFTC with respect to coverage of
options and futures positions by registered investment companies and, if the
guidelines so require, will set aside cash, U.S. government securities, high
grade liquid debt securities and/or other liquid assets permitted by the SEC
and CFTC in a segregated custodial account in the amount prescribed. Securities
held in a segregated account cannot be sold while the futures or options
position is outstanding, unless replaced with other permissible assets, and
will be marked-to-market daily.
 
  Options. The Fund may use options for any lawful purpose consistent with its
investment objectives such as hedging or managing risk but not for speculation.
An option is a contract in which the "holder" (the buyer) pays a certain amount
(the "premium") to the "writer" (the seller) to obtain the right, but not the
obligation, to buy from the writer (in a "call") or sell to the writer (in a
"put") a specific asset at an agreed upon price (the "strike price" or
"exercise price") at or before a certain time (the "expiration date"). The
holder pays the premium at inception and has no further financial obligation.
The holder of an option will benefit from favorable movements in the price of
the underlying asset but is not exposed to corresponding losses due to adverse
movements in the value of the underlying asset. The writer of an option will
receive fees or premiums but is exposed to losses due to changes in the value
of the underlying asset. The Fund may purchase (buy) or write (sell) put and
call options on assets, such as securities, currencies, commodities, and
indices of debt and equity securities ("underlying assets") and enter into
closing transactions with respect to such options to terminate an existing
position. Options used by the Fund may include European-, American- and
Bermuda-style options. If an option is exercisable only at maturity, it is a
"European" option; if it is also exercisable prior to maturity, it is an
"American" option; if it is exercisable only at certain times, it is a
"Bermuda" option.
 
  The Fund may purchase and write put and call options and enter into closing
transactions with respect to such options to terminate an existing position.
The purchase of call options serves as a long hedge, and the purchase of put
options serves as a short hedge. Writing put or call options can enable the
Fund to enhance income by reason of the premiums paid by the purchaser of such
options. Writing call options serves as a limited short hedge because declines
in the value of the hedged investment would be offset to the extent of the
premium received for writing the option. If the security appreciates to a price
higher than the exercise price of the call option, however, it can be expected
that the option will be exercised and the Fund will be obligated to sell the
security at less than its market value or will be obligated to purchase the
security at a price greater than that at which the security must be sold under
the option. All or a portion of any assets used as cover for OTC options
written by the Fund would be considered illiquid to the extent described under
"Investment Policies and Techniques--Illiquid Securities." Writing put options
serves as a limited long hedge because increases in the value of the hedged
investment would be offset to the extent of the premium received for writing
the option. If the security depreciates to a price lower than the exercise
price of the put option, it can be expected that the put option will be
exercised and the Fund will be obligated to purchase the security at more than
its market value.
 
  The value of an option position will reflect, among other things, the
historical price volatility of the underlying investment, the current market
value of the underlying investment, the time remaining until expiration, the
relationship of the exercise price to the market price of the underlying
investment, and general market conditions.
 
  The Fund may effectively terminate its right or obligation under an option by
entering into a closing transaction. For example, the Fund may terminate its
obligation under a call or put option that it has written by purchasing an
identical call or put option; this is known as a closing purchase transaction.
Conversely, the Fund may terminate a position in a put or call option it had
purchased by writing an identical put or call option; this
 
                                      S-13
<PAGE>
 
is known as a closing sale transaction. Closing transactions permit the Fund to
realize the profit or limit the loss on an option position prior to its
exercise or expiration.
 
  The Fund may purchase or write both exchange-traded and OTC options.
Exchange-traded options are issued by a clearing organization affiliated with
the exchange on which the option is listed that, in effect, guarantees
completion of every exchange-traded option transaction. In contrast, OTC
options are contracts between the Fund and the other party to the transaction
("counterparty") (usually a securities dealer or a bank) with no clearing
organization guarantee. Thus, when the Fund purchases or writes an OTC option,
it relies on the counter party to make or take delivery of the underlying
investment upon exercise of the option. Failure by the counter party to do so
would result in the loss of any premium paid by the Fund as well as the loss of
any expected benefit of the transaction.
 
  The Fund's ability to establish and close out positions in exchange-listed
options depends upon the existence on a liquid market for such instruments. The
Fund intends to purchase or write only those exchange-traded options for which
there appears to be a liquid secondary market. However, there can be no
assurance that such a market will exist at any particular time. Closing
transactions can be made for OTC options only by negotiating directly with the
counter party, or by a transaction in the secondary market if any such market
exists. Although the Fund will enter into OTC options only with counter parties
that are expected to be capable of entering into closing transactions, there is
no assurance that the Fund will in fact be able to close at OTC options at
favorable prices prior to expiration. In the event of insolvency of the counter
party, the Fund may be unable to close out an OTC option position at any time
prior to its expiration. If the Fund were unable to effect a closing
transaction for an option it had purchased, it would have to exercise the
option to realize any profit.
 
  The Fund also may engage in options transactions on indices in much the same
manner as the options on securities discussed above, except the index options
may serve as a hedge against overall fluctuations in the securities market in
general. The writing and purchasing of options is a highly specialized activity
that involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions. An imperfect correlation
between the options and securities markets may detract from the effectiveness
of attempted hedging. For instance, the Fund's ability to effectively hedge all
or a portion of the securities in its portfolio, in anticipation of or during a
market decline through transactions in put options on indices, depends on the
degree to which price movements in the underlying index correlate with the
price movements of the securities held by the Fund. Inasmuch as the Fund's
securities will not duplicate the components of an index, the correlation will
not be perfect. Consequently, the Fund will bear the risk that the prices of
its securities being hedged will not move in the same amount as the prices of
its put options on the indexes. It is also possible that there may be a
negative correlation between the index and the Fund's securities which would
result in a loss on both such securities and the options on indexes acquired by
the Fund. The purchase of index options also involves the risk that the premium
and transaction costs paid by the Fund in purchasing an option will be lost as
a result of unanticipated movements in prices of the securities comprising the
index on which the option is based.
 
  The hours of trading for options may not conform to the hours during which
the underlying securities are traded. To the extent that the options markets
close before the markets for the underlying securities, significant price and
rare movements can take place in the underlying markets that cannot be
reflected in the options markets. Options transactions may result in
significantly higher transaction costs and portfolio turnover for the Fund.
 
  Federal Income Tax Treatment of Options. Certain option transactions have
special federal income tax results for the Fund. Expiration of a call option
written by the Fund will result in short-term capital gain. If the call option
is exercised, the Fund will realize a gain or loss from the sale of the
security covering the call option and, in determining such gain or loss, the
option premium will be included in the proceeds of the sale.
 
  If the Fund writes options, or purchases puts that are subject to the loss
deferral rules of Section 1092 of the Internal Revenue Code of 1986, as amended
(the "Code"), any losses on such options transactions, to the
 
                                      S-14
<PAGE>
 
extent they do not exceed the unrecognized gains on the securities covering the
options, may be subject to deferral until the securities covering the options
have been sold.
 
  In the case of transactions involving "nonequity options," as defined in Code
Section 1256, the Fund will treat any gain or loss arising from the lapse,
closing out or exercise of such positions as 60% long-term and 40% short-term
capital gain or loss as required by Section 1256 of the Code. In addition, such
positions must be marked-to-market as of the last business day of the year, and
gain or loss must be recognized for federal income tax purposes in accordance
with the 60%/40% rule discussed above even though the position has not been
terminated. A "nonequity option" includes an option with respect to any group
of stocks or a stock index if there is in effect a designation by the CFTC of a
contract market for a contract based on such group of stock or indexes. For
example, options involving stock indexes such as the S&P 500 Index would be
"nonequity options" within the meaning of Code Section 1256.
 
  Futures Contracts. The Fund may enter into futures contracts (hereinafter
referred to as "Futures" or "Futures Contracts"), including index Futures as a
hedge against movements in the securities markets, in order to establish more
definitely the effective return on securities held or intended to be acquired
by the Fund, to manage risk or for other purposes permissible under the CEA.
The Fund's hedging may include sales of Futures as an offset against the effect
of expected declines in the prices of securities and purchases of Futures as an
offset against the effect of expected increases in the prices of securities.
The Fund will not enter into Futures Contracts which are prohibited under the
CEA and will, to the extent required by regulatory authorities, enter only into
Futures Contracts that are traded on a national futures exchanges and are
standardized as to maturity date and underlying financial instrument. The
principal interest rate Futures exchanges in the United States are the Board of
Trade of the City of Chicago and the Chicago Mercantile Exchange. Futures
exchanges and trading are regulated under the CEA by the CFTC.
 
  An interest rate futures contract provides for the future sale by one party
and purchase by another party of a specified amount of a specific financial
instrument (e.g., a debt security) or currency for a specified price at a
designated date, time and place. An index Futures Contract is an agreement
pursuant to which the parties agree to take or make delivery of an amount of
cash equal to the difference between the value of the index at the close of the
last trading day of the contract and the price at which the index Futures
Contract was originally written. Transaction costs are incurred when a Futures
Contract is bought or sold and margin deposits must be maintained. A Futures
Contract may be satisfied by delivery or purchase, as the case may be, of the
instrument or by payment of the change in the cash value of the index. More
commonly, Futures Contracts are closed out prior to delivery by entering into
an offsetting transaction in a matching Futures Contract. Although the value of
an index might be a function of the value of certain specified securities, no
physical delivery of those securities is made. If the offsetting purchase price
is less than the original sale price, a gain will be realized; if it is more, a
loss will be realized. Conversely, if the offsetting sale price is more than
the original purchase price, a gain will be realized; if it is less, a loss
will be realized. The transaction costs must also be included in these
calculations. There can be no assurance, however, that the Fund will be able to
enter into an offsetting transaction with respect to a particular Futures
Contract at a particular time. If the Fund is not able to enter into an
offsetting transaction, the Fund will continue to be required to maintain the
margin deposits on the Futures Contract.
 
  Margin is the amount of funds that must be deposited by the Fund with its
custodian in a segregated account in the name of the futures commission
merchant in order to indicate Futures trading and to maintain the Fund's open
positions in Futures Contracts. A margin deposit is intended to ensure the
Fund's performance of the Futures Contract. The margin required for a
particular Futures Contract is set by the exchange on which the Futures
Contract is traded and may be significantly modified from time to time by the
exchange during the term of the Futures Contract. Futures Contracts are
customarily purchased and sold on margins that my range upward from less than
5% of the value of the Futures Contract being traded.
 
 
                                      S-15
<PAGE>
 
  If the price of an open Futures Contract changes (by increase in the case of
a sale or by decrease in the case of a purchase) so that the loss on the
Futures Contract reaches a point at which the margin on deposit does not
satisfy margin requirements, the broker will require an increase in the margin.
However, if the value of a position increases because of favorable price
changes in the Futures Contract so that the margin deposit exceeds
the required margin, the broker will pay the excess to the Fund. In computing
daily net asset value, the Fund will mark to market the current value of its
open Futures Contracts. The Fund expects to earn interest income on its margin
deposits.
 
  Because of the low margin deposits required, Futures trading involves an
extremely high degree of leverage. As a result, a relatively small price
movement in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example, if at the time of purchase, 10% of
the value of the Futures Contract is deposited as margin, a subsequent 10%
decrease in the value of the Futures Contract would result in a total loss of
the margin deposit, before any deduction for the transaction costs, if the
account were then closed out. A 15% decrease would result in a loss equal to
150% of the original margin deposit, if the Futures Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess
of the amount initially invested in the Futures Contract. However, the Fund
would presumably have sustained comparable losses if, instead of the Futures
Contract, it had invested in the underlying financial instrument and sold it
after the decline.
 
  Most United States Futures exchanges limit the amount of fluctuation
permitted in Futures Contract prices during a single trading day. The day limit
establishes the maximum amount that the price of a Futures Contract may vary
either up or down from the previous day's settlement price at the end of a
trading session. Once the daily limit has been reached in a particular type of
Futures Contract, no trades may be made on that day at a price beyond that
limit. The daily limit governs only price movement during a particular trading
day and therefore does not limit potential losses, because the limit may
prevent the liquidation of unfavorable positions. Futures Contracts prices have
occasionally moved to the daily limit for several consecutive trading days with
little or no trading, thereby preventing prompt liquidation of Futures
positions and subjecting some Futures traders to substantial losses.
 
  There can be no assurance that a liquid market will exist at a time when the
Fund seeks to close out a Futures position. The Fund would continue to be
required to meet margin requirements until the position is closed, possibly
resulting in a decline in the Fund's net asset value. In addition, many of the
contracts discussed above are relatively new instruments without a significant
trading history. As a result, there can be no assurance that an active
secondary market will develop or continue to exist.
 
  A public market exists in Futures Contracts covering a number of indexes,
including, but not limited to, the Standard & Poor's 500 Index, the Standard &
Poor's 100 Index, the NASDAQ 100 Index, the Value Line Composite Index and the
New York Stock Exchange Composite Index.
 
  Options on Futures. The Fund may also purchase or write put and call options
on Futures contracts and enter into closing transactions with respect to such
options to terminate an existing position. A futures option gives the holder
the right, in return of the premium paid, to assume a long position (call) or
short position (put) in a Futures Contract at a specified exercise price prior
to the expiration of the option. Upon exercise of a call option, the holder
acquires a long position in the Futures Contract and the writer is assigned the
opposite short position. In the case of a put option, the opposite is true.
Prior to exercise or expiration, a futures option may be closed out by an
offsetting purchase or sale of a futures option of the same series.
 
  The Fund may use options on Futures Contracts in connection with hedging
strategies. Generally, these strategies would be applied under the same market
and market sector conditions in which the Fund uses put and call options on
securities or indexes. The purchase of put options on Futures contracts is
analogous to the
 
                                      S-16
<PAGE>
 
purchase of puts on securities or indexes so as to hedge the Fund's securities
holdings against the risk of declining market prices. The writing of a call
option or the purchasing of a put option on a Futures Contract constitutes a
partial hedge against declining prices of the securities which are deliverable
upon exercise of the Futures contract. If the futures price at expiration of a
written call option is below the exercise price, the Fund will retain the full
amount of the option premium which provides a partial hedge against any decline
that may have occurred in the Fund's holdings of securities. If the futures
price when the option is exercised is above the exercise price, however, the
Fund will incur a loss, which may be offset, in whole or in part, by the
increase in the value of the securities held by the Fund that were being
hedged. Writing a put option or purchasing a call option on a Futures Contract
serves as a partial hedge against an increase in the value of the securities
the Fund intends to acquire.
 
  As with investments in Futures Contracts, the Fund is required to deposit and
maintain margin with respect to put and call options on Futures Contracts
written by it. Such margin deposits will vary depending on the nature of the
underlying Futures Contract (and the related initial margin requirements), the
current market value of the option, and other futures positions held by the
Fund. The Fund will set aside in a segregated account at the Fund's custodian
liquid assets, such as cash, U.S. government securities or other high grade
liquid debt obligations equal in value to the amount due on the underlying
obligation. Such segregated assets will be marked-to market daily, and
additional assets will be placed in the segregated account whenever the total
value of the segregated account falls below the amount due on the underlying
obligation.
 
  The risks associated with the use of options on Futures Contracts include the
risk that the Fund may close out its position as a writer of an option only if
a liquid secondary market exists for such options, which cannot be assured. The
Fund's successful use of options on Futures Contracts depends on NAC's ability
to correctly predict the movement in prices of Futures Contracts and the
underlying instruments, which may prove to be incorrect. In addition, there may
be imperfect correlation between the instruments being hedged and the Futures
Contract subject to the option. Certain characteristics of the futures market
might increase the risk that movements in the prices of futures contracts or
options on futures contracts might not correlate perfectly with movements in
the prices of the investment being hedged. For example, all participants in the
futures and options on futures contracts markets are subject to daily variation
margin calls and might be compelled to liquidate futures or options on futures
contracts positions whose prices are moving unfavorably to avoid being subject
to further calls. These liquidations could increase the price volatility of the
instruments and distort the normal price relationship between the futures or
options and the investments being hedged. Also, because of initial margin
deposit requirements in the futures markets are less onerous than margin
requirements in the securities markets, there might be increased participation
by speculators in the futures markets. This participation also might cause
temporary price distortions. In addition, activities of large traders in both
the futures and securities markets involving arbitrage, "program trading," and
other investments strategies might result in temporary price distortions.
 
  Federal Income Tax Treatment of Futures Contracts. For federal income tax
purposes, the Fund is required to recognize as income for each taxable year its
net unrealized gains and losses on Futures Contracts as of the end of the year,
as well as gains and loses actually realized during the year. Except for
transactions in Futures Contracts that are classified as part of a "mixed
straddle" under Code Section 1256, any gain or loss recognized with respect to
a Futures Contract is considered to be 60% long-term capital gain or loss and
40% short-term capital gain or loss, without regard to the holding period of
the Futures Contract. In the case of a Futures transaction not classified as a
"mixed straddle," the recognition of losses may be required to be deferred to a
later taxable year.
 
  Sales of Futures Contracts that are intended to hedge against a change in the
value of securities held by the Fund may affect the holding period of such
securities and, consequently, the nature of the gain or loss on such securities
upon disposition.
 
                                      S-17
<PAGE>
 
  The Fund will distribute to shareholders annually any net capital gains which
have been recognized for federal income tax purposes (including unrealized
gains at the end of the Fund's fiscal year) on Futures transactions. Such
distributions will be combined with distributions of capital gains realized on
the Fund's other investments and shareholders will be advised of the nature of
the payments.
 
  Risks and Special Considerations Concerning Derivatives. The use of
derivative instruments involves certain general risks and considerations as
described below. The specific risks pertaining to certain types of derivative
instruments are described in the sections that follow.
 
    (1) Market Risk. Market risk is the risk that the value of the underlying
  assets may go up or down. Adverse movements in the value of an underlying
  asset can expose the Fund to losses. Market risk is the primary risk
  associated with derivative transactions. Derivative instruments may include
  elements of leverage and, accordingly, fluctuations in the value of the
  derivative instrument in relation to the underlying asset may be magnified.
  The successful use of derivative instruments depends upon a variety of
  factors, particularly the investment adviser's ability to predict movements
  of the securities, currencies, and commodities markets, which may require
  different skills than predicting changes in the prices of individual
  securities. There can be no assurance that any particular strategy adopted
  will succeed. A decision to engage in a derivative transaction will reflect
  the investment adviser's judgment that the derivative transaction will
  provide value to the Fund and its shareholders and is consistent with the
  Fund's objectives, investment limitations, and operating policies. In
  making such a judgment, the investment adviser will analyze the benefits
  and risks of the derivative transaction and weigh them in the context of
  the Fund's overall investments and investment objective.
 
    (2) Credit Risk. Credit risk is the risk that a loss may be sustained as
  a result of the failure of a counterpart to comply with the terms of a
  derivative instrument. The counterparty risk for exchange-traded
  derivatives is generally less than for privately-negotiated or OTC
  derivatives, since generally a clearing agency, which is the issuer or
  counterparty to each exchange-traded instrument, provides a guarantee of
  performance. For privately-negotiated instruments, there is no similar
  clearing agency guarantee. In a all transactions, the Fund will bear the
  risk that the counterparty will default, and this could result in a loss of
  the expected benefit of the derivative transaction and possibly other
  losses to the Fund. The Fund will enter into transactions in derivative
  instruments only within counterparties that the investment adviser
  reasonably believes are capable of performing under the contract.
 
    (3) Correlation Risk. Correlation risk is the risk that there might be an
  imperfect correlation, or even no correlation, between price movements of a
  derivative instrument and price movements of investments being hedged. When
  a derivative transaction is used to completely hedge another position,
  changes in the market value of the combined position (the derivative
  instrument plus the position being hedged) resulted from an imperfect
  correlation between the price movements of the two instruments. With a
  perfect hedge, the value of the combined position remains unchanged with
  any change in the price of the underlying assert. With an imperfect hedge,
  the value of the derivative instrument and its hedge are not perfectly
  correlated. For example, if the value of a derivative instrument used in a
  short hedge (such as writing a call option, buying a put option or selling
  a futures contract) increased by less than the decline in value of the
  hedged investments, the hedge would not be perfectly correlated. This might
  occur due to factors unrelated to the value of the investments being
  hedged, such as speculative or other pressures on the markets in which
  these instruments are traded. The effectiveness of hedges using instruments
  on indices will depend, in part, on the degree of correlation between price
  movements in the index and the price movements in the investments being
  hedged.
 
    (4) Liquidity Risk. Liquidity risk is the risk that a derivative
  instrument cannot be sold, closed out, or replaced quickly at or very close
  to its fundamental value. Generally, exchange contracts are very liquid
 
                                      S-18
<PAGE>
 
  because the exchange clearinghouse is the counterparty of every contract.
  OTC transactions are less liquid than exchange-traded derivatives since
  they often can only be closed out with the other party to the transactions.
  The Fund might be required by applicable regulatory requirements to
  maintain assets as "cover," maintain segregated accounts, and/or make
  margin payments when it takes positions in derivative instruments involving
  obligations to third parties (i.e., instruments other than purchase
  options). If the Fund is unable to close out its positions in such
  instruments, it might be required to continue to maintain such assets or
  accounts or make such payments until the position expires, matures, or is
  closed out. These requirements might impair the Fund's ability to sell a
  security or make an investment at a time when it would otherwise be
  favorable to do so, or require that the Fund sell a portfolio security at a
  disadvantageous time. The Fund's ability to sell or close out a position in
  an instrument prior to expiration or maturity depends upon the existence of
  a liquid secondary market or, in the absence of such a market, the ability
  and willingness of the counterparty to enter into a transaction closing out
  the position. Due to liquidity risk, there is no assurance that any
  derivatives position can be sold or closed out at a time and price that is
  favorable to the Fund.
 
    (5) Legal Risk. Legal risk is the risk of loss caused by the
  unenforceability of a party's obligations under the derivative. While a
  party seeking price certainty agrees to surrender the potential upside in
  exchange for downside protection, the party taking the risk is looking for
  a positive payoff. Despite this voluntary assumption of risk, a
  counterparty that has lost money in a derivative transaction may try to
  avoid payment by exploiting various legal uncertainties about certain
  derivative products.
 
    (6) Systemic or "Interconnection" Risk. Systemic or interconnection risk
  is the risk that a disruption in the financial markets will cause
  difficulties for all market participants. In other words, a disruption in
  one market will spill over into other markets, perhaps creating a chain
  reaction. Much of the OTC derivatives market takes place among the OTC
  dealers themselves, thus creating a large interconnected web of financial
  obligations. This interconnectedness raises the possibility that a default
  by one large dealer could create losses for other dealers and destabilize
  the entire market for OTC derivative instruments.
 
Other Investment Policies and Techniques
 
  Illiquid Securities. The Fund may invest in illiquid securities (i.e.,
securities that are not readily marketable). For purposes of this restriction,
illiquid securities include, but are not limited to, restricted (securities the
disposition of which is restricted under the federal securities laws),
securities that may only be resold pursuant to Rule 144A under the Securities
Act of 1933, as amended (the "Securities Act"), but that are deemed to be
illiquid; and repurchase agreements with maturities in excess of seven days.
However, the Fund will not acquire illiquid securities if, as a result, such
securities would comprise more than 15% of the value of the Fund's net assets.
The Board of Directors or its delegate has the ultimate authority to determine,
to the extent permissible under the federal securities laws, which securities
are liquid or illiquid for purposes of this 15% limitation. The Board of
Directors has delegated to NAC the day-to-day determination of the illiquidty
of any security, although it has retained oversight and ultimate responsibility
for such determinations. Although no definitive liquidity criteria are used,
the Board of Directors has directed NAC to look to such factors as (i) the
nature of the market for a security (including the institutional private resale
market; the frequency of trades and quotes for the security; the number of
dealers willing to purchase or sell the security; and the amount of time
normally needed to dispose of the security, the method of soliciting offers and
the mechanics of transfer), (ii) the terms of certain securities or other
instruments allowing for the disposition to a third party or the issuer thereof
(e.g., certain repurchase obligations and demand instruments), and (iii) other
permissible relevant facts.
 
  Restricted securities may be sold only in privately negotiated transactions
or in a public offering with respect to which a registration statement is in
effect under the Securities Act. Where registration is required, the Fund may
be obligated to pay all or part of the registration expenses and a considerable
period may elapse between the
 
                                      S-19
<PAGE>
 
time of the decision to sell and the time the Fund may be permitted to sell a
security under an effective registration statement. If, during such a period,
adverse market conditions were to develop, the Fund might obtain a less
favorable price than that which prevailed when it decided to sell. Illiquid
securities will be priced at fair value as determined in good faith by the
Board of Directors or its delegate. If, through the appreciation of illiquid
securities or the depreciation of liquid securities, the Fund should be in a
position where more than 15% of the value of its net assets are invested in
illiquid securities, including restricted securities which are not readily
marketable, the Fund will take such steps as is deemed advisable, if any, to
protect liquidity.
 
  Dollar Roll Transactions. The Fund may enter into "dollar roll" transactions,
which involve the sale of pass-through securities together with a commitment to
purchase similar, but not identical, securities at a later date. The Fund
assumes the rights and risks of ownership, including the risk of price and
yield fluctuations as of the time of the agreement.
 
  Warrants. The Fund may invest in warrants if, after giving effect thereto,
not more than 5% of its net assets will be invested in warrants other than
warrants acquired in units or attached to other securities. Of such 5%, not
more than 2% of its assets at the time of purchase may be invested in warrants
that are not listed on the New York Stock Exchange or the American Stock
Exchange. Investing in warrants is purely speculative in that they have no
voting rights, pay no dividends, and have no rights with respect to the assets
of the corporation issuing them. Warrants basically are options to purchase
equity securities at a specific price for a specific period of time. They do
not represent ownership of the securities but only the right to buy them.
Warrants are issued by the issuer of the security, which may be purchased on
their exercise. The prices of warrants do not necessarily parallel the prices
of the underlying securities.
 
  When-Issued Securities. The Fund may from time to time purchase securities on
a "when-issued" or other delayed-deliver basis. The price of securities
purchased in such transactions is fixed at the time the commitment to purchase
is made, but delivery and payment for the securities take place at a later
date. Normally, the settlement date occurs within 45 days of the purchase.
During the period between the purchase and settlement, no payment is made by
the Fund to the issuer and no interest is accrued on debt securities or
dividend income is earned on equity securities, although the Fund continues to
earn income on the assets that will be used to pay for the securities. Delayed-
delivery commitments involve a risk of loss if the value of the security to be
purchased declines prior to the settlement date, which risk is in addition to
the risk of decline in value of the Fund's other assets. While securities
purchased in delayed-delivery transactions may be sold prior to the settlement
date, the Fund intends to purchase such securities with the purpose of actually
acquiring them. At the time the Fund makes the commitment to purchase a
security in a delayed-delivery transaction, it will record the transaction and
reflect the value of the security in determining its net asset value. The Fund
does not believe that net asset value will be adversely affected by purchases
of securities in delayed-delivery transactions.
 
  The Fund will maintain cash, U.S. government securities, and high grade
liquid debt securities equal in value to commitments for delayed-delivery
securities. Such segregated securities will mature or, if necessary, be sold on
or before the settlement date. When the time comes to pay for delayed-delivery
securities, the Fund will meet its obligations form then-available cash flow,
sale of the securities held in the segregated account described above, sale of
other securities, or, although it would not normally expect to do so, from the
sale of the delayed-delivery securities themselves (which may have a market
value greater or less than the Fund's payment obligation).
 
  Foreign Securities. The Fund will limit foreign bond investments to 20% of
its bonds, and will invest only in U.S. dollar-denominated securities of
foreign issuers whose headquarters are located in a country that is (i) rated
investment grade quality by Moody's Investors Service, Standard & Poor's, Duff
& Phelp's or Fitch Investors Service or (ii) a member of the Organization for
Economic Cooperation and Development. The Fund may also invest up to 20% of its
equity allocation in foreign securities traded in the U.S., including ADRs.
 
                                      S-20
<PAGE>
 
  Foreign securities are affected by the fact that in many countries there is
less publicly available information about issuers than is available in the
reports and ratings published about companies in the U.S. and companies may not
be subject to uniform accounting, auditing and financial reporting standards.
Other risks inherent in foreign investments include expropriation; confiscatory
taxation; withholding taxes on dividends and interest; less extensive
regulation of foreign brokers, securities markets and issuers; diplomatic
developments; and political or social instability. Foreign economies may differ
favorably or unfavorably from the U.S. economy in various respects, and many
foreign securities are less liquid and their prices tend to be more volatile
than comparable U.S. securities. From time to time, foreign securities may be
difficult to liquidate rapidly without adverse price effects.
 
  Subject to its investment objectives and policies, the Fund may invest in
foreign securities by purchasing depositary receipts, including ADRs.
Generally, ADRs, in registered form, are denominated in U.S. dollars and are
designed for use in the U.S. securities markets. For purposes of the Fund's
investment policies, ADRs are deemed to have the same classification as the
underlying securities they represent, except that ADRs shall be treated as
indirect foreign investments. Thus, an ADR representing ownership of common
stock will be treated as common stock. ADRs do not eliminate all of the risks
associated with directly investing in the securities of foreign issuers.
 
  Depositary receipts may be available through "sponsored" or "unsponsored"
facilities. A sponsored facility is established jointly by a depositary and the
issuer of the security underlying the receipt. An unsponsored facility may be
established by a depositary without participation by the issuer of the security
underlying the receipt. There are greater risks associated with holding
unsponsored depositary receipts. For example, if the Fund holds an unsponsored
depositary receipt, it will generally bear all of the costs of establishing the
unsponsored facility.
In addition, the depositary of an unsponsored facility frequently is under no
obligation to distribute shareholder communications received from the issuer of
the deposited security or to pass through to the holders of the receipts voting
rights with respect to the deposited securities.
 
  Foreign Currency Transactions. The Fund may engage in foreign currency
forward contracts, options, and futures transactions. The Fund will enter into
foreign currency transactions for hedging and other permissible risk management
purposes only. Foreign currency futures and options contracts are traded in the
U.S. on regulated exchanges such as the Chicago Mercantile Exchange, the Mid-
America Commodities Exchange, and the Philadelphia Stock Exchange. If the Fund
invests in a currency futures or options contract, it must make a margin
deposit to secure performance of such contract. With respect to investments in
currency futures contracts, the Fund may also be required to make a variation
margin deposit because the value of futures contracts fluctuates from purchase
to maturity. In addition, the Fund may segregate assets to cover their futures
contracts obligations.
 
    (1) Currency Risks. The exchange rates between the U.S. dollar and
  foreign currencies depend upon such factors as supply and demand in the
  currency exchange markets, international balances of payments, governmental
  intervention, speculation, and other economic and political conditions.
  Although the Fund values its assets daily in U.S. dollars, the Fund may not
  convert its holdings of foreign currencies to U.S. dollars daily. The Fund
  may incur conversion costs when it converts its holdings to another
  currency. Foreign exchange dealers may realize a profit on the difference
  between the price at which the Fund buy and sell currencies. The Fund will
  engage in foreign currency exchange transactions in connection with its
  portfolio investments. The Fund will conduct its foreign currency exchange
  transactions either on a spot (i.e., cash) basis at the spot rate
  prevailing in the foreign currency exchange market or through forward
  contracts to purchase or sell foreign contracts.
 
    (2) Forward Foreign Currency Exchange Contracts. The Fund may enter into
  forward currency exchange contracts. Forward foreign currency exchange
  contracts may limit potential gains that could result from a
 
                                      S-21
<PAGE>
 
  positive change in such currency relationships. The investment adviser
  believes that it is important to have the flexibility to enter into forward
  foreign currency exchange contracts whenever it determines that it is in
  the Fund's best interest to do so. The Fund will not speculate in foreign
  currency exchange.
 
    The Fund will not enter into forward currency exchange contracts or
  maintain a net exposure in such contracts that it would be obligated to
  deliver an amount of foreign currency in excess of the value of its
  portfolio securities or other assets denominated in that currency or, in
  the case of a "cross-hedge," denominated in a currency or currencies that
  the investment adviser believes will tend to be closely correlated with
  that currency with regard to price movements. Generally, the Fund will not
  enter into a forward foreign currency exchange contract with a term longer
  than one year.
 
    (3) Foreign Currency Options. A foreign currency option provides the
  option buyer with the right to buy or sell a stated amount of foreign
  currency at the exercise price on a specified date or during the option
  period. The owner of a call option has the right, but not the obligation,
  to buy the currency. Conversely, the owner of a put option has the right,
  but not the obligation, to sell the currency. When the option is exercised,
  the seller (i.e., writer) of the option is obligated to fulfill the terms
  of the sold option. However, either the seller or the buyer may, in the
  secondary market, close its position during the option period at any time
  prior to expiration.
 
    A call option on foreign currency generally rises in value if the
  underlying currency appreciates in value, and a put option on a foreign
  currency generally rises in value if the underlying currency depreciates in
  value. Although purchasing a foreign currency option can protect the Fund
  against an adverse movement in the value of a foreign currency, the option
  will not limit the movement in the value of such currency. For example, if
  the Fund held securities denominated in a foreign currency that was
  appreciating and had purchased a foreign currency put to hedge against a
  decline in the value of the currency, the Fund would not have to exercise
  its put option. Likewise, if the Fund entered into a contract to purchase a
  security denominated in foreign currency and, in conjunction with that
  purchase, purchased a foreign currency call option to hedge against a rise
  in value of the currency, and if the value of the currency instead
  depreciated between the date of purchase and the settlement date, the Fund
  would not have to exercise its call. Instead, the Fund could acquire in the
  spot market the amount of foreign currency needed for settlement.
 
    (4) Special Risks Associated with Foreign Currency Options. Buyers and
  sellers of foreign currency options are subject to the same risks that
  apply to options generally. In addition, there are certain risks associated
  with foreign currency options. The markets in foreign currency options are
  relatively new, and the Fund's ability to establish and close out positions
  on such options is subject to the maintenance of a liquid secondary market.
  Although the Fund will not purchase or write such options unless and until,
  in the opinion of the investment adviser, the market for them has developed
  sufficiently to ensure that the risks in connection with such options are
  not greater than risks in connection with the underlying currency, there
  can be no assurance that a liquid secondary market will exist for a
  particular option at any specific time.
 
    In addition, options on foreign currencies are affected by all of those
  factors that influence foreign exchange rates and investments generally.
  The value of a foreign currency option depends upon the value of the
  underlying currency relative to the U.S. dollar. As a result, the price of
  the option position may vary with changes in the value of either or both
  currencies and may have no relationship to the investment merits of a
  foreign security. Because foreign currency transactions occurring in the
  interbank market involve substantially larger amounts than those that may
  be involved in the use of foreign currency options, investors may be
  disadvantaged by having to deal in an odd lot market (generally consisting
  of transactions of less than $1 million) for the underlying foreign
  currencies at prices that are less favorable than for round lots.
 
                                      S-22
<PAGE>
 
    There is no systematic reporting of last sale information for foreign
  currencies or any regulatory requirements that quotations available through
  dealers or other market sources be firm or revised on a timely basis.
  Available quotation information is generally representative of very large
  transactions in the interbank market and thus may not reflect relatively
  smaller transactions (i.e., less than $1 million) where rates may be less
  favorable. The interbank market in foreign currencies is a global, around-
  the clock market. To the extent that the U.S. options markets are closed
  while the markets for the underlying currencies remain open, significant
  price and rate movements may take place in the underlying markets that
  cannot be reflected in the options markets until they reopen.
 
    (5) Foreign Currency Futures Transactions. By using foreign currency
  futures contracts and options on such contracts, the Fund may be able to
  achieve many of the same objectives as they would through the use of
  forward foreign currency exchange contracts. The Fund may be able to
  achieve these objectives possibly more effectively and at a lower cost by
  using futures transactions instead of forward foreign currency exchange
  contracts.
 
    (6) Special Risks Associated with Foreign Currency Futures Contracts and
  Related Options. Buyers and sellers of foreign currency futures contracts
  are subject to the same risks that apply to the use of futures generally.
  In addition, there are risks associated with foreign currency futures
  contracts and their use as a hedging device similar to those associated
  with options on currencies, as described above.
 
  Options on foreign currency futures contracts may involve certain additional
risks. Trading options on foreign currency futures contracts is relatively new.
The ability to establish and close out positions on such options is subject to
the maintenance of a liquid secondary market. To reduce this risk, the Fund
will not purchase or write options on foreign currency futures contracts unless
and until, in the opinion of the investment adviser, the market for such
options has developed sufficiently that the risks in connection with such
options are not greater than the risks in connection with transactions in the
underlying foreign currency futures contracts. Compared to the purchase or sale
of foreign currency futures contracts, the purchase of call or put options on
futures contracts involves less potential risk to the Fund because the maximum
amount at risk is the premium paid for the option (plus transaction costs).
However, there may be circumstances when the purchases of a call or put option
on a futures contract would result in a loss, such as when there is no movement
in the price of the underlying currency or futures contract.
 
  Lending of Portfolio Securities. The Fund may lend its portfolio securities,
up to 33 1/3% of its total assets, including collateral received, to broker-
dealers or institutional investors. Such loans will be secured continuously by
collateral at least equal to the value of the securities lent by "marking to
market" daily. The Fund will continue to receive the equivalent of the interest
or dividends paid by the issuer of the securities lent and will retain the
right to call, upon notice, the lent securities. The Fund may also receive
interest on the investment of the collateral or a fee from the borrower as
compensation for the loan. As with other extensions of credit, there are risks
of delay in recovery or even loss of rights in the collateral should the
borrower of the securities fail financially. However, loans will be made only
to firms deemed by the investment adviser to be of good standing.
 
  Portfolio Turnover. Under normal market conditions, the Fund expects to be
relatively low in order to reduce trading costs and realization of taxable
capital gains. In the event the Fund were to have a turnover rate of 100% of
more in any year, it would result in the payment by the Fund of increased
brokerage costs and could result in the payment by shareholders of increased
taxes on realized investment gains.

MANAGEMENT
 
 
  The management of the Corporation, including general supervision of the
duties performed for the Fund under the investment management agreement, is the
responsibility of its Board of Directors. The Corporation currently has eight
directors, two of whom are "interested persons" (as the term "interested
persons" is defined in the Investment Company Act of 1940) and six of whom are
"disinterested persons." The names and business addresses of the directors and
officers of the Corporation and their principal occupations and other
affiliations during the past five years are set forth below, with those
directors who are "interested persons" of the Corporation indicated by an
asterisk.

  NAC is a wholly owned subsidiary of John Nuveen & Co. Incorporated
("Nuveen"), the Fund's principal underwriter. Nuveen and its affiliates have
sponsored or underwritten more than $60 billion of investment company
securities. Over 1,300,000 individuals have invested to date in Nuveen
investment products. Founded in 1898, Nuveen is a subsidiary of The John Nuveen
Company which, in turn, is approximately 78% owned by The St. Paul Companies,
Inc. ("St. Paul"). St. Paul is located in St. Paul, Minnesota and is
principally engaged in providing property-liability insurance through
subsidiaries.
 
  NAC's portfolio managers call upon the resources of Nuveen's Research
Department.
 
  The Fund, the other Nuveen funds, NAC and other related entities have adopted
a code of ethics which essentially prohibits all Nuveen fund management
personnel, including Nuveen fund portfolio managers, from engaging in personal
investments which compete or interfere with, or attempt to take advantage of,
the Fund's anticipated or actual portfolio transactions, and is designed to
assure that the interests of Fund shareholders are placed before the interests
of Nuveen personnel in connection with personal investment transactions.

PORTFOLIO TRANSACTIONS
 
  NAC is responsible for decisions to buy and sell securities for the Fund and
for the Placement of the Fund's securities business, the negotiation of the
commissions to be paid on brokered transactions, the prices for principal
trades in securities, and the allocation of portfolio brokerage and principal
business. It is the policy of NAC to seek the best execution at the best
security price available with respect to each transaction, and with respect to
each brokered transaction, in light of the overall quality of brokerage and
research services provided. The best price to the Fund means the best net price
without regard to the mix between purchase or sale price and commission, if
any. Purchases may be made from underwriters, dealers, and, on occasion, the
issuers. Commissions will be paid on the Fund's futures and options
transactions, if any. The purchase price of portfolio securities purchased from
an underwriter or dealer may include underwriting commissions and dealer
spreads. The Fund may pay mark-ups on principal transactions. In selecting
broker-dealers and in negotiating commissions, the portfolio manager considers,
among other things, the firm's reliability, the quality of its execution
services on a continuing basis and its financial condition. Brokerage will not
be allocated based on the sale of a Fund's shares.
 
  Section 28(e) of the Securities Act of 1934 ("Section 28(e)") permits an
investment adviser, under certain circumstances, to cause an account to pay a
broker or dealer who supplies brokerage and research services a commission for
effecting a transaction in excess of the amount of commission another broker or
dealer would have charged for effecting the transaction. Brokerage and research
services include (a) furnishing advice as to the value of securities, the
advisability of investing, purchasing or selling securities, and the
availability of securities or purchasers or sellers of securities; (b)
furnishing analyses and reports concerning issuers, industries, securities,
economic factors and trends, portfolio strategy, and the performance of
accounts; and (c) effecting securities transactions and performing functions
incidental thereto (such as clearance, settlement and custody).
 
  In light of the above, in selecting brokers, NAC considers investment and
market information and other research, such as economic, securities and
performance measurement research, provided by such brokers, and the quality and
reliability of brokerage services, including execution capability, performance,
and financial responsibility. Accordingly, the commissions charged by any such
broker may be greater than the amount another firm might charge if NAC
determines in good faith that the amount of such commissions is reasonable in
relation to the value of the research information and brokerage services
provided by such broker to NAC or the Fund. NAC believes that the research
information received in this manner provides the Fund with benefits by
supplementing the research otherwise available to the Fund. The Management
Agreement provide that such higher commission will not be paid by the Fund
unless NAC determines in good faith that the amount is reasonable in relation
to the services provided. The investment advisory fees paid by the Fund to NAC
are not reduced as a result of receipt by NAC of research services.
 
  NAC places portfolio transactions for other advisory accounts managed by it.
Research services furnished by firms through with the Fund effects its
securities transactions may be used by NAC in servicing all of its accounts;
not all of such services may be used by NAC in connection with the Fund. NAC
believes it is not possible to measure separately the benefits from research
services to each of the accounts (including the Fund) managed by it. Because
the volume and nature of the trading activities of the accounts are not
uniform, the amount of commissions in excess of those charged by another broker
paid by each account for brokerage and research services will vary. However,
NAC believes such costs to the Fund will not be disproportionate to the
benefits received by the Fund on a continuing basis. NAC seeks to allocate
portfolio transactions equitably whenever concurrent decisions are made to
purchase or sell securities by the Fund and another advisory account. In some
cases, this procedure could have an adverse effect on the price or the amount
of securities available to the Fund. In making such allocation between the Fund
and other advisory accounts, the main factors considered by NAC are the
respective investment objectives, the relative size of portfolio holdings of
the same or
 
                                      S-30
<PAGE>
 
comparable securities, the availability of cash for investment and the size of
investment commitments generally held.
 
  For the year ended June 30, 1998, the Fund paid brokerage commissions of
$51,714, $81,938 and $62,962, respectively.
 
  Under the 1940 Act, the Fund may not purchase portfolio securities from any
underwriting syndicate of which Nuveen is a member except under certain limited
conditions set forth in Rule 10f-3. The Rule sets forth requirements relating
to, among other things, the terms of a security purchased by the Fund, the
amount of securities that may be purchased in any one issue and the assets of
the Fund that may be invested in a particular issue. In addition, purchases of
securities made pursuant to the terms of the Rule must be approved at least
quarterly by the Board of Directors, including a majority of the directors who
are not interested persons of the Corporation.
 
NET ASSET VALUE
 
  As stated in the Prospectus, the net asset value of the shares of the Fund
will be determined separately for each class of the Fund's shares by The Chase
Manhattan Bank, the Fund's custodian, as of the close of trading (normally 4:00
p.m. Eastern Time) on each day on which the New York Stock Exchange (the
"Exchange") is normally open for trading. The Exchange is not open for trading
on New Year's Day, Washington's Birthday, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The net asset
value per share of a class of shares of the Fund will be computed by dividing
the value of the Fund's assets attributable to the class, less the liabilities
attributable to the class, by the number of shares of the class outstanding.
 
  In determining net asset value for the Fund, the Fund's custodian utilizes
the valuations of portfolio securities furnished by a pricing service approved
by the directors. Securities for which quotations are not readily available are
valued at fair value as determined by the pricing service using methods which
include consideration of the following: yields or prices of fixed-income
securities of comparable quality, type of issue, coupon, maturity and rating;
indications as to value from dealers; and general market conditions. The
pricing service may employ electronic data processing techniques and/or a
matrix system to determine valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Corporation under the
general supervision of the Board of Directors.
 
FEDERAL INCOME TAX MATTERS
 
  The following discussion of federal income tax matters is based upon the
advice of Bell, Boyd & Lloyd, counsel to the Corporation.
 
  The Fund intends to qualify under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code") for tax treatment as a regulated investment
company. In order to qualify as a regulated investment company, the Fund must
satisfy certain requirements relating to the source of its income,
diversification of its assets, and distributions of its income to shareholders.
First, the Fund must derive at least 90% of its annual gross income (including
tax-exempt interest) from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock or
securities, foreign currencies or other income (including but not limited to
gains from options and futures) derived with respect to its business of
investing in such stock or securities (the "90% gross income test"). Second,
the Fund must diversify its holdings so that, at the close of each quarter of
its taxable year, (i) at least 50% of the value of its total assets is
comprised of cash, cash items,
 
                                      S-31
<PAGE>
 
United States Government securities, securities of other regulated investment
companies and other securities limited in respect of any one issuer to an
amount not greater in value than 5% of the value of its total assets and to not
more than 10% of the outstanding voting securities of such issuer, and (ii) not
more than 25% of the value of the total assets is invested in the securities of
any one issuer (other than United States Government securities and securities
of other regulated investment companies) or two or more issuers controlled by
the Fund and engaged in the same, similar or related trades or businesses.
 
  As a regulated investment company, the Fund will not be subject to federal
income tax in any taxable year for which it distributes at least 90% of the sum
of (i) its "investment company taxable income" (which includes dividends,
taxable interest, taxable original issue discount and market discount income,
income from securities lending, net short-term capital gain in excess of long-
term capital loss, and any other taxable income other than "net capital gain"
(as defined below) and is reduced by deductible expenses) and (ii) its net tax-
exempt interest (the excess of its gross tax-exempt interest income over
certain disallowed deductions). The Fund may retain for investment its net
capital gain (which consists of the excess of its net long-term capital gain
over its short-term capital loss). However, if the Fund retains any net capital
gain or any investment company taxable income, it will be subject to tax at
regular corporate rates on the amount retained. If the Fund retains any capital
gain, it may designate the retained amount as undistributed capital gains in a
notice to its shareholders who, if subject to federal income tax on long-term
capital gains, (i) will be required to include in income for federal income tax
purposes, as long-term capital gain, their shares of such undistributed amount,
and (ii) will be entitled to credit their proportionate shares of the tax paid
by the Fund against their federal income tax liabilities if any, and to claim
refunds to the extent the credit exceeds such liabilities. For federal income
tax purposes, the tax basis of shares owned by a shareholder of the Fund will
be increased by an amount equal under current law to the difference between the
amount of undistributed capital gains included in the shareholder's gross
income and the tax deemed paid by the Shareholder under clause (ii) of the
preceding sentence. The Fund intends to distribute at least annually to its
shareholders all or substantially all of its net tax-exempt interest and any
investment company taxable income and net capital gain.
 
  Treasury regulations permit a regulated investment company, in determining
its investment company taxable income and net capital gain, i.e., the excess of
net long-term capital gain over net short-term capital loss for any taxable
year, to elect (unless it has made a taxable year election for excise tax
purposes as discussed below) to treat all or part of any net capital loss, any
net long-term capital loss or any net foreign currency loss incurred after
October 31 as if it had been incurred in the succeeding year.
 
  Distributions by the Fund of net interest received from certain taxable
temporary investments (such as certificates of deposit, commercial paper and
obligations of the U.S. Government, its agencies and instrumentalities) and net
short-term capital gains realized by the Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional shares.
Any net long-term capital gains realized by the Fund and distributed to
shareholders in cash or additional shares, will be taxable to shareholders as
long-term capital gains regardless of the length of time investors have owned
shares of the Fund. Distributions by the Fund that do not constitute ordinary
income dividends or capital gain dividends will be treated as a return of
capital to the extent of (and in reduction of) the shareholder's tax basis in
his or her shares. Any excess will be treated as gain from the sale of his or
her shares, as discussed below.
 
  If the Fund engages in hedging transactions involving financial futures and
options, these transactions will be subject to special tax rules, the effect of
which may be to accelerate income to a Fund, defer the Fund's losses, cause
adjustments in the holding periods of the Fund's securities, convert long-term
capital gains into short-term capital gains and convert short-term capital
losses into long-term capital losses. These rules could therefore affect the
amount, timing and character of distributions to shareholders.
 
                                      S-32
<PAGE>
 
  Prior to purchasing shares in the Fund, an investor should carefully consider
the impact of dividends or distributions which are expected to be or have been
declared, but not paid. Any dividend or distribution declared shortly after a
purchase of such shares prior to the record date will have the effect of
reducing the per share net asset value by the per share amount of the dividend
or distribution.
 
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during the following
January, will be treated as having been distributed by the Fund (and received
by the shareholders) on December 31.
 
  The redemption or exchange of the shares of the Fund normally will result in
capital gain or loss to the shareholders. Generally, a shareholder's gain or
loss will be long-term gain or loss if the shares have been held for more than
one year. Present law taxes both long- and short-term capital gains of
corporations at the rates applicable to ordinary income. For non-corporate
taxpayers, however, net capital gains (i.e., the excess of net long-term
capital gain over net short-term capital loss) with respect to securities will
be taxed at a maximum rate of 20%, while short-term capital gains and other
ordinary income will be taxed at a maximum rate of 39.6%. Because of the
limitations on itemized deductions and the deduction for personal exemptions
applicable to higher income taxpayers, the effective tax rate may be higher in
certain circumstances.
 
  All or a portion of a sales charge paid in purchasing shares of the Fund
cannot be taken into account for purposes of determining gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to
the extent shares of the Fund or another fund are subsequently acquired without
payment of a sales charge pursuant to the reinvestment or exchange privilege.
Any disregarded portion of such charge will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. In addition, no
loss will be allowed on the redemption or exchange of shares of the Fund if the
shareholder purchases other shares of the Fund (whether through reinvestment of
distributions or otherwise) or the shareholder acquires or enters into a
contract or option to acquire securities that are substantially identical to
shares of the Fund within a period of 61 days beginning 30 days before and
ending 30 days after such redemption or exchange. If disallowed, the loss will
be reflected in an adjustment to the basis of the shares acquired.
 
  In order to avoid a 4% federal excise tax, the Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
realized capital gains over its realized capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year) and 100% of
any taxable ordinary income and the excess of realized capital gains over
realized capital losses for the prior year that was not distributed during such
year and on which the Fund paid no federal income tax. For purposes of the
excise tax, a regulated investment company may reduce its capital gain net
income (but not below its net capital gain) by the amount of any net ordinary
loss for the calendar year. The Fund intends to make timely distributions in
compliance with these requirements and consequently it is anticipated that it
generally will not be required to pay the excise tax.
 
  If in any year the Fund should fail to qualify under Subchapter M for tax
treatment as a regulated investment company, the Fund would incur a regular
corporate federal income tax upon its income for that year, and distributions
to its shareholders would be taxable to shareholders as ordinary dividend
income for federal income tax purposes to the extent of the Fund's earnings and
profits.
 
  The Fund is required in certain circumstances to withhold 31% of taxable
dividends and certain other payments paid to non-corporate holders of shares
who have not furnished to the Fund their correct taxpayer identification number
(in the case of individuals, their social security number) and certain
certifications, or who are otherwise subject to backup withholding.

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

PERFORMANCE INFORMATION
 
  The Fund may quote its yield, distribution rate, average annual total return
or cumulative total return in reports to shareholders, sales literature and
advertisements each of which will be calculated separately for each class.
 
  In accordance with a standardized method prescribed by rules of the SEC,
yield is computed by dividing the net investment income per share earned during
the specified one month or 30-day period by the maximum offering price per
share on the last day of the period, according to the following formula:

                                  (a-b) 
                          Yield=2[(---) +1)/6/ -1]
                                  (cd )
 
  In the above formula, a = dividends and interest earned during the period; b
= expenses accrued for the period (net of reimbursements); c = the average
daily number of shares outstanding during the period that were entitled to
receive dividends; and d = the maximum offering price per share on the last day
of the period. In the case of Class A shares, the maximum offering price
includes the current maximum front-end sales charge of 5.25%.
 
  In computing yield, the Fund follows certain standardized accounting
practices specified by SEC rules. These practices are not necessarily
consistent with those that the Fund uses to prepare its annual and interim
financial statements in conformity with generally accepted accounting
principles. Thus, yield may not equal the income paid to shareholders or the
income reported in the Fund's financial statements.
 
  The Fund may from time to time in its advertising and sales materials report
a quotation of its current distribution rate. The distribution rate represents
a measure of dividends distributed for a specified period. Distribution rate is
computed by taking the most recent monthly dividend per share, multiplying it
by 12 to annualize it, and dividing by the appropriate price per share (e.g.,
net asset value for purchases to be made without a load such as reinvestments
from Nuveen Defined Portfolios, or the maximum public offering price). The
distribution rate differs from yield and total return and therefore is not
intended to be a complete measure of performance. Distribution rate may
sometimes differ from yield because the Fund may be paying out more than its
earning and because it may not include the effect of amortization of bond
premiums to the extent such premiums arise after the bonds were purchased.
   
  The distribution rates as of June 30, 1998, based on the maximum public
offering price then in effect for the Fund, and assuming the imposition of the
maximum sales charge for Class A Shares of 5.25%, were 4.66% for Class A Shares
and 4.33% for Class C Shares. The maximum sales charge for Class A Shares
currently in effect is 5.75%.     
 
  All total return figures assume the reinvestment of all dividends and measure
the net investment income generated by, and the effect of any realized and
unrealized appreciation or depreciation of, the underlying investments in the
Fund over a specified period of time. Average annual total return figures are
annualized and therefore represent the average annual percentage change over
the specified period. Cumulative total return figures are not annualized and
represent the aggregate percentage or dollar value change over a stated period
of time. Average annual total return and cumulative total return are based upon
the historical results of the Fund and are not necessarily representative of
the future performance of the Fund.
 
  The average annual total return quotation is computed in accordance with a
standardized method prescribed by SEC rules. The average annual total return
for a specific period is found by taking a hypothetical, $1,000 investment
("initial investment") in Fund shares on the first day of the period, reducing
the amount to reflect the maximum sales charge, and computing the "redeemable
value" of that investment at the end of the period. The redeemable value is
then divided by the initial investment, and this quotient is taken to the Nth
root (N representing the number of years in the period) and 1 is subtracted
from the result, which is then
 
                                      S-35
<PAGE>
 
expressed as a percentage. The calculation assumes that all income and capital
gains distributions have been reinvested in Fund shares at net asset value on
the reinvestment dates during the period. Average annual and cumulative total
returns may also be presented in advertising and sales literature without the
inclusion of sales charges.
 
  Total returns for the oldest class of the Fund reflect actual performance for
all periods. For other classes, total returns reflect actual performance for
periods since class inception, and the oldest class's performance for periods
prior to inception, adjusted for the differences in sales charges and fees
(where such fees are higher in the newer class) between the classes.
 
  The inception dates for each class of the Fund's shares are as follows:

*Since inception returns are reflected since the change in investment

  Class A Shares of the Fund are sold at net asset value plus a current maximum
sales charge of 5.75% of the offering price. This current maximum sales charge
will typically be used for purposes of calculating performance figures. Yield,
returns and net asset value of each class of shares of the Fund will fluctuate.
Factors affecting the performance of the Fund include general market
conditions, operating expenses and investment management. Any additional fees
charged by a securities representative or other financial services firm would
reduce returns described in this section. Shares of the Fund are redeemable at
net asset value, which may be more or less than original cost.
 
  In reports or other communications to shareholders or in advertising and
sales literature, the Fund may also compare their performance with that of: (1)
the Consumer Price Index ; (2) other fixed-income mutual funds or equity mutual
fund indexes as reported by Lipper Analytical Services, Inc. ("Lipper"),
Morningstar, Inc. ("Morningstar"), Wiesenberger Investment Companies Service
("Wiesenberger") and CDA Investment Technologies, Inc. ("CDA") or similar
independent services which monitor the performance of mutual funds, or other
industry or financial publications such as Barron's, Changing Times, Forbes and
Money Magazine. Performance comparisons by these indexes, services or
publications may rank mutual funds over different periods of time by means of
aggregate, average, year-by-year, or other types of total return and
performance figures. Any given performance quotation or performance comparison
should not be considered as representative of the performance of the Fund for
any future period.
 
  There are differences and similarities between the investments which the Fund
may purchase and the investments measured by the indexes and reporting services
which are described herein. The Consumer Price Index is generally considered to
be a measure of inflation. Lipper, Morningstar, Wiesenberger and CDA are
 
                                      S-36
<PAGE>
 
widely recognized mutual fund reporting services whose performance calculations
are based upon changes in net asset value with all dividends reinvested and
which do not include the effect of any sales charges.
 
  The Fund may from time to time in its advertising and sales materials compare
its current yield or total return with the yield or total return on taxable
investments such as corporate or U.S. Government bonds, bank certificates of
deposit (CDs) or money market funds. These taxable investments have investment
characteristics that differ from those of the Fund. U.S. Government bonds, for
example, are long-term investments backed by the full faith and credit of the
U.S. Government, and bank CDs are generally short-term. FDIC-insured
investments, which pay fixed principal and interest but are subject to
fluctuating rollover rates. Money market funds are short-term investments with
stable net asset values, fluctuating yields and special features enhancing
liquidity.

ADDITIONAL INFORMATION ON THE PURCHASE AND REDEMPTION OF FUND SHARES
 
  As described in the Prospectus, the Fund provides you with alternative ways
of purchasing Fund shares based upon your individual investment needs and
preferences.
 
  Each class of shares of the Fund represents an interest in the same portfolio
of investments. Each class of shares is identical in all respects except that
each class bears its own class expenses, including distribution and
administration expenses, and each class has exclusive voting rights with
respect to any distribution or service plan applicable to its shares. As a
result of the differences in the expenses borne by each class of shares, net
income per share, dividends per share and net asset value per share will vary
among the Fund's classes of shares. There are no conversion, preemptive or
other subscription rights, except that Class B shares automatically convert
into Class A shares as described below.
 
  Shareholders of each class will share expenses proportionately for services
that are received equally by all shareholders. A particular class of shares
will bear only those expenses that are directly attributable to that class,
where the type or amount of services received by a class varies from one class
to another. For example, class-specific expenses generally will include
distribution and service fees.
 
  The expenses to be borne by specific classes of shares may include (i)
transfer agency fees attributed to a specific class of shares, (ii) printing
and postage expenses related to preparing and distributing materials such as
shareholder reports, prospectuses and proxy statements to current shareholders
of a specific class of shares, (iii) SEC and state securities registration fees
incurred by a specific class, (iv) the expense of administrative personnel and
services required to support the shareholders of a specific class of shares,
(v) litigation or other legal expenses relating to a specific class of shares,
(vi) directors' fees or expenses incurred as a result of issues relating to a
specific class of shares, (vii) accounting expenses relating to a specific
class of shares and (viii) additional incremental expenses subsequently
identified and determined to be property allocated to one or more classes of
shares.
 
Initial and Subsequent Purchases of Shares
 
  You may buy Fund shares through Authorized Dealers or by calling or directing
your financial adviser to call Nuveen toll-free at 800-257-8787. You may pay
for your purchases by Federal Reserve draft or by check made payable to
"Dividend and Growth Fund, Class [A], [B], [C], [R]"' delivered to the
financial adviser through whom the investment is to be made for forwarding to
Nuveen Investor Services. When making your initial investment, you must also
furnish the information necessary to establish you Fund account by completing
and enclosing with your payment the application form attached to the Prospectus
(the "Application Form"). After your initial investment, you may make
subsequent purchases at any time by forwarding to your financial adviser or
Nuveen Investor Services a check, in the amount of your purchase, made payable
to "Dividend and Growth Fund, Class [A], [B], [C], [R]," and indicating on the
check your account number. All payments need to be in U.S. dollars and should
be sent directly to Nuveen Investor Services at P.O. Box 5186, Bowling Green
Station, New York, NY 10004-5186. A check drawn on a foreign bank or payable
other than to the order of your Fund generally will not be acceptable. You may
also wire Federal Funds directly to Nuveen Investor Services, but you may be
charge a fee for this. For instructions on how to make Fund purchases by wire
transfer, call Nuveen toll-free at 800-257-8787.
 
Purchase Price
 
  The price at which you purchase a class of Fund shares is based on the next
calculation of the net asset value for that share class after the order is
placed. The net asset value per share of each share class is determined as of
the close of trading (normally 4:00 p.m. Eastern Time) on each day the New York
Stock Exchange is open for business. See "Net Asset Value," for a description
of how net asset value is calculated.

Minimum Investment Requirements
 
  The minimum initial investment is $3,000 per Fund share class ($1,000 for a
Traditional/Roth IRA Account; $500 for an Education IRA Account), $50 through
systematic investment plan accounts and $500 for accounts opened through fee-
based programs for which the program sponsor has established a single master
account with the Fund's transfer agent and performs all sub-accounting services
related to that account. Additional purchases may be in amounts of $50 or more.
These minimums may be changed at any time by the Fund. There are exceptions to
these minimums for shareholders who qualify under reinvestment programs.
 
Systematic Investment Programs
 
  The Fund offers you several opportunities to capture the benefits of "dollar
cost averaging" through systematic investment programs. In a regularly followed
dollar cost averaging program, you would purchase more shares when Fund share
prices are lower and fewer shares when Fund share prices are higher, so that
the average price paid for Fund shares is less than the average price of the
Fund shares over the same time period. Dollar cost averaging does not assure
profits or protect against losses in a steadily declining market. Since dollar
cost averaging involves continuous investment regardless of fluctuating price
levels, you should consider your financial ability to continue investing in
declining as well as rising markets before deciding to invest in this way. The
Fund offers two different types of systematic investment programs:
 
  Systematic Investment Plan. The initial minimum investment for a systematic
investment plan is $50, once you have established a Fund account, you may make
regular investments in an amount of $50 or more each month by authorizing
Nuveen Investor Services to draw preauthorized checks on your bank account.
There is no obligation to continue payments and you may terminate your
participation at any time at your discretion. No charge in additional to the
applicable sales charge is made in connection with this Plan, and there is no
cost to your Fund. To obtain an application form for the Systematic Investment
Plan, check the applicable box on the Application Form or call Nuveen toll-free
at 800-257-8787.
 
  Payroll Direct Deposit Plan. Once you have established a Fund account, you
may, with your employer's consent, make regular investments in Fund shares of
$25 or more per pay period (meeting the monthly minimum of $50) by authorizing
your employer to deduct this amount automatically from your paycheck. There is
no obligation to continue payments and you may terminate your participation at
any time at your discretion. No charge in addition to the applicable sales
charge is made for this Plan, and there is no cost to your Fund. To obtain an
application form for the Payroll Direct Deposit Plan, check the applicable box
on the Application Form or call Nuveen toll-free at 800-257-8787.
 
Class A Shares
 
  Class A Shares may be purchased at a public offering price equal to the
applicable net asset value per share plus an up-front sales charge imposed at
the time of purchase as set forth in the Prospectus. Shareholders may qualify
for a reduced sales charge, or the sales charge may be waived in its entirety,
as described below. Class A Shares are also subject to an annual service fee of
 .25%. See "Distribution and Service Plan." Set forth below is an example of the
method of computing the offering price of the Class A Shares. The example
assumes a purchase on June 30, 1998 of Class A Shares from the Fund aggregating
less than $50,000 subject to the schedule of sales charges set forth in the
current Prospectus at a price based upon the net asset value of the Class A
Shares.

(*) Nuveen pays Authorized Dealers a commission equal to the sum of 1.00% of
    the first $2.5 million, plus 0.50% of the next $2.5 million, plus 0.25% of
    any amount over $5 million. Unless the Authorized Dealer waived the
    commission, you may be assessed a contingent deferred sales charge (CDSC)
    of 1.00% if you redeem any of your Class A Shares within 18 months of
    purchase. The CDSC is calculated on the lower of your purchase price or
    redemption proceeds.
 
REDUCTION OR ELIMINATION OF UP-FRONT SALES CHARGE ON CLASS A SHARES
 
  Rights of Accumulation. You may qualify for a reduced sales charge on a
purchase of Class A Shares of the Fund if the amount of your purchase, when
added to the value that day of all of your prior purchases of shares of the
Fund or of another Nuveen Mutual Fund, or Nuveen exchange-traded fund, or units
of a Nuveen Defined Portfolio, on which an up-front sales charge or ongoing
distribution fee is imposed, or is normally imposed, falls within the amounts
stated in the Class A Sales Charges and Commissions table in "How to Select a
Purchase Option" in the Prospectus. You or your financial adviser must notify
Nuveen or the Fund's transfer agent of any cumulative discount whenever you
plan to purchase Class A Shares of the Fund that you wish to qualify for a
reduced sales charge.
 
  Letter of Intent. You may qualify for a reduced sales charge on a purchase of
Class A Shares of the Fund if you plan to purchase Class A Shares of Nuveen
Mutual Funds over the next 13 months and the total amount of your purchases
would, if purchased at one time, qualify you for one of the reduced sales
charges shown in the Class A Sales Charges and Commissions table in "How to
Select a Purchase Option" in the Prospectus. In order to take advantage of this
option, you must complete the applicable section of the Application Form or
sign and deliver either to an Authorized Dealer or to the Fund's transfer agent
a written Letter of Intent in a form acceptable to Nuveen. A Letter of Intent
states that you intend, but are not obligated, to purchase over the next 13
months a stated total amount of Class A shares that would qualify you for a
reduced sales charge shown above. You may count shares of a Nuveen Mutual Fund
that you already own on which you paid an up-front sales charge or an ongoing
distribution fee and any Class B or Class C Shares of a Nuveen Mutual Fund that
you purchase over the next 13 months towards completion of your investment
program, but you will receive a reduced sales charge only on new Class A Shares
you purchase with a sales charge over the 13 months. You cannot count towards
completion of your investment program Class A Shares that you purchase without
a sales charge through investment of distributions from a Nuveen Mutual Fund or
a Nuveen Defined Portfolio, or otherwise.
 
                                      S-40
<PAGE>
 
  By establishing a Letter of Intent, you agree that your first purchase of
Class A Shares of the Fund following execution of the Letter of Intent will be
at least 5% of the total amount of your intended purchases. You further agree
that shares representing 5% of the total amount of your intended purchases will
be held in escrow pending completion of these purchases. All dividends and
capital gains distributions on Class A Shares held in escrow will be credited
to your account. If total purchases, less redemptions, prior to the expiration
of the 13 month period equal or exceed the amount specified in your Letter of
Intent, the Class A Shares held in escrow will be transferred to your account.
If the total purchases, less redemptions, exceed the amount specified in your
Letter of Intent and thereby qualify for a lower sales charge than the sales
charge specified in your Letter of Intent, you will receive this lower sales
charge retroactively, and the difference between it and the higher sales charge
paid will be used to purchase additional Class A Shares on your behalf. If the
total purchases, less redemptions, are less than the amount specified, you must
pay Nuveen an amount equal to the difference between the amounts paid for these
purchases and the amounts which would have been paid if the higher sales charge
had been applied. If you do not pay the additional amount within 20 days after
written request by Nuveen or your financial adviser, Nuveen will redeem an
appropriate number of your escrowed Class A Shares to meet the required
payment. By establishing a Letter of Intent, you irrevocably appoint Nuveen as
attorney to given instructions to redeem any or all of your escrowed shares,
with full power of substitution in the premises.
 
  You or your financial adviser must notify Nuveen or the Fund's transfer agent
whenever you make a purchase of Fund shares that you wish to be covered under
the Letter of Intent option.
 
  Reinvestment of Nuveen Defined Portfolio Distributions. You may purchase
Class A Shares without an up-front sales charge by reinvestment of
distributions from any of the various defined portfolios sponsored by Nuveen.
In addition, you may also invest the proceeds from termination of such defined
portfolios into Class A Shares at NAV. There is no initial or subsequent
minimum investment requirement for such reinvestment purchases.
 
  Group Purchase Programs. If you are a member of a qualified group, you may
purchase Class A Shares of the Fund or of another Nuveen Mutual Fund at the
reduced sales charge applicable to the group's purchases taken as a whole. A
"qualified group" is one which has previously been in existence, has a purpose
other than investment, has ten or more participating members, has agreed to
include Fund sales publications in mailings to members and has agreed to comply
with certain administrative requirements relating to its group purchases.
 
  Under any group purchase program, the minimum initial investment in Class A
Shares of the Fund or portfolio for each participant is $50 provided that the
group invests at least $3,000 in the Fund, and the minimum monthly investment
in Class A Shares of the Fund or portfolio by each participant in the program
is $50. No certificate will be issued for any participant's account. All
dividends and other distributions by the Fund will be reinvested in additional
Class A Shares of the Fund. No participant may utilize a systematic withdrawal
program.
 
  To establish a group purchase program, both the group itself and each
participant must fill out special application materials, which the group
administrator may obtain from the group's financial adviser, by calling Nuveen
toll-free at (800) 257-8787.
 
  Class A shares of the Fund may be purchased at net asset value without a
sales charge, and may be purchased by the following categories of investors:
 
  . investors purchasing $1,000,000 or more
 
  . officers, directors and former directors of the Corporation or any fund
    sponsored by Nuveen, any parent company of Nuveen or subsidiaries
    thereof;
 
  . bona fide, full-time and retired employees and directors of Nuveen, any
    parent company of Nuveen, and subsidiaries thereof, or their immediate
    family members;
 
                                      S-41
<PAGE>
 
  . any person who, for at least 90 days, has been an officer, director or
    bona fide employee of any Authorized Dealer, or their immediate family
    members;
 
  . officers and directors of bank holding companies that make Fund shares
    available directly or through subsidiaries or bank affiliates or their
    immediate family members;
 
  . bank or broker-affiliated trust departments investing funds over which
    they exercise exclusive discretionary investment authority and that are
    held in a fiduciary, agency, advisory, custodial or similar capacity;
 
  . investors purchasing on a periodic fee, asset-based fee or no transaction
    fee basis through a broker-dealer sponsored mutual fund purchase program;
    and
 
  . clients of investment advisers, financial planners or other financial
    intermediaries that charge periodic or asset-based fees for their
    services.
 
  . any eligible employer-sponsored qualified defined contribution retirement
    plan. Eligible plans are those with at least 25 employees and which
    either (a) make an initial purchase of one or more Nuveen Mutual Funds
    aggregating $500,000 or more or (b) execute a Letter of Intent to
    purchase in the aggregate $500,000 or more of fund shares. Nuveen will
    pay Authorized Dealers a sales commission on such purchases equal to
    1.00% of the first $2.5 million, plus .50% of the next $2.5 million, plus
    .25% of any amount purchased over $5.0 million. For this category of
    investors a contingent deferred sales charge of 1% will be assessed on
    redemptions within 18 months of purchase, unless waived.
 
  For investors that purchased Class A Shares at net asset value because they
purchased such shares through an eligible employer-sponsored qualified defined
contribution plan or because the purchase amount equaled or exceeded $1 million
and the Authorized Dealer did not waive the sales commission, a contingent
deferred sales charge of 1.00% will be assessed on redemptions within 18 months
of purchase.
 
  Any Class A Shares purchased pursuant to a special sales charge waiver must
be acquired for investment purposes and on the condition that they will not be
transferred or resold except through redemption by the Fund. You or your family
adviser must notify Nuveen or the Fund's transfer agent whenever you make a
purchase of Class A Shares of the Fund that you wish to be covered under these
special sales charge waivers.
 
  Class A Shares of the Fund may be issued at net asset value without a sales
charge in connection with the acquisition by the Fund of another investment
company. All purchases under the special sales charge waivers will be subject
to minimum purchase requirements as established by the Fund.
 
  In determining the amount of your purchase of Class A Shares of the Fund that
may qualify for a reduced sales charge, the following purchases may be
combined: (1) all purchases by a trustee or other fiduciary for a single trust,
estate or fiduciary account; (2) all purchases by individuals and their
immediate family members (i.e., their spouses, parents, children, grandparents,
grandchildren parents-in-law, sons- and daughters-in-law, siblings, a sibling's
spouse, and a spouse's siblings); or (3) all purchases made through a group
purchase program as described above.
 
Class B Shares
 
You may purchase Class B Shares at a public offering price equal to the
applicable net asset value per share without any up-front sales charge. Since
Class B Shares are sold without an initial sales charge, the full amount of
your purchase payment will be invested in Class B Shares. Class B Shares are
subject to an annual distribution fee of .75% to compensate Nuveen for its
costs in connection with the sale of Class B Shares, and are also subject to an
annual service fee of .25% to compensate Authorized Dealers for providing you
with ongoing financial advice and other account services.
 
                                      S-42
<PAGE>
 
  You may be subject to a CDSC if you redeem your Class B shares prior to the
end of the sixth year after purchase. See "Reduction or Elimination of
Contingent Deferred Sales Charge" below. Nuveen compensates Authorized Dealers
for sales of Class B Shares at the time of sale at the rate of 4.00% of the
amount of Class B Shares purchased, which represents a sales commission of
3.75% plus an advance on the first year's annual service fee of .25%.
 
  Class B Shares acquired through the reinvestment of dividends are not subject
to a CDSC. Any CDSC will be imposed on the lower of the redeemed shares' cost
or net asset value at the time of redemption.
 
  Class B Shares will automatically convert to Class A Shares eight years after
purchase. The purpose of the conversion is to limit the distribution fees you
pay over the life of your investment. All conversions will be done at net asset
value without the imposition of any sales load, fee, or other charge, so that
the value of each shareholder's account immediately before conversion will be
the same as the value of the account immediately after conversion. Class B
Shares acquired through reinvestment of distributions will convert into Class A
Shares based on the date of the initial purchase to which such shares relate.
For this purpose, Class B Shares acquired through reinvestment of distributions
will be attributed to particular purchases of Class B Shares in accordance with
such procedures as the Board of Directors may determine from time to time.
Class B Shares that are converted to Class A Shares will remain subject to an
annual service fee that is identical in amount for both Class B Shares and
Class A Shares. Since net asset value per share of the Class B Shares and the
Class A Shares may differ at the time of conversion, a shareholder may receive
more or fewer Class A Shares than the number of Class B Shares converted. Any
conversion of Class B Shares into Class A Shares will be subject to the
continuing availability of an opinion of counsel or a private letter ruling
from the Internal Revenue Service to the effect that the conversion of shares
would not constitute a taxable event under federal income tax law. Conversion
of Class B Shares into Class A Shares might be suspended if such an opinion or
ruling were no longer available.
 
Class C Shares
 
  You may purchase Class C Shares without any up-front sales charge at a price
equal to their net asset value. Class C Shares are subject to an annual
distribution fee of .75% to compensate Nuveen for its costs in connection with
the sale of Class C Shares. Class C Shares are also subject to an annual
service fee of .25% to compensate Authorized Dealers for providing you with on-
going financial advice and other account services. Nuveen compensates
Authorized Dealers for sales of Class C Shares ar the time of the sale at a
rate of 1% of the amount of Class C Shares purchased, which represents a sales
commission of .75% plus an advance on the first year's annual service fee of
 .25%. See "Distribution and Service Plan."
 
  Redemptions of Class C Shares within 12 months of purchase may be subject to
a CDSC of 1% of the lower of the purchase price or redemption proceeds. Because
Class C Shares do not convert to Class A Shares and continue to pay an annual
distribution fee indefinitely, Class C Shares should normally not be purchased
by an investor who expects to hold shares for significantly longer than eight
years.
 
  Holders of Class C Shares acquired on or before January 31, 1997 can convert
those shares to Class A Shares of the Fund at the shareholder's affirmative
request six years after date of purchase. Holders of Class C Shares must submit
their request to the transfer agent no later than the last business day of the
71st month following the month in which they purchased their Class C shares.
Holders of Class C Shares purchased after that date will not have the option to
convert those shares to Class A Shares.

Class R Share Purchase Eligibility
 
  Class R Shares are available for single purchases of $2.5 million or more and
for purchases using dividends and capital gains distributions on Class R
Shares. Class R Shares also are available for the following categories of
investors:
 
  . officers, directors and former directors of the Corporation and their
    immediate family members or trustees/directors of any fund, sponsored by
    Nuveen, any parent company of Nuveen and subsidiaries thereof and their
    immediate family members;
 
  . bona fide, full-time and retired employees and directors of Nuveen, any
    parent company of Nuveen, and subsidiaries thereof, or their immediate
    family members;
 
  . any person who, for at least 90 days, has been an officer, director or
    bona fide employee of any Authorized Dealer, or their immediate family
    members;
 
  . officers and directors of bank holding companies that make Fund shares
    available directly or through subsidiaries or bank affiliates, or their
    immediate family members;
 
  . bank or broker-affiliated trust departments investing funds over which
    they exercise exclusive discretionary investment authority and that are
    held in a fiduciary, agency, advisory, custodial or similar capacity;
 
  . investors purchasing on a periodic fee, asset-based fee or no transaction
    fee basis through a broker-dealer sponsored mutual fund purchase program;
 
  . clients of investment advisers, financial planners or other financial
    intermediaries that charge periodic or asset-based fees for their
    services.
 
  . Any shares purchased by investors falling within any of the first four
    categories listed above must be acquired for investment purposes and on
    the condition that they will not be transferred or resold except through
    redemption by the fund.
 
  In addition, purchasers of Nuveen Defined Portfolios may reinvest their
distributions from such defined portfolios in Class R Shares, if, before
September 6, 1994, such purchasers had elected to reinvest distributions in
Nuveen Fund shares. Shareholders may exchange their Class R Shares of any
Nuveen Fund into Class R Shares of any other Nuveen Fund. Also, you may
exchange Class R Shares of the Fund for Class A Shares without a sales charge
if the current net asset value of those Class R Shares is at least $3,000 or
you already own Class A Shares of the Fund.
 
  The reduced sales charge programs may be modified or discontinued by the
Funds at any time. To encourage their participation, the Fund waives the sales
charge on Class A Shares and offers Class R Shares to trustees and officers of
the Corporation and other affiliated persons of the Corporation and Nuveen as
noted above.
 
  If you are eligible to purchase either Class R Shares or Class A Shares
without a sales charge at net asset value, you should be aware of the
differences between these two classes of shares. Class A Shares are subject to
an annual service fee to compensate Authorized Dealers for providing you with
ongoing account service. Class R Shares are not subject to a distribution or
service fee and, consequently, holders of Class R Shares may not receive the
sale types or levels of services from Authorized Dealers. In choosing between
Class A Shares and Class R Shares, you should weigh the benefits of the
services to be provided by Authorized Dealers against the annual service fee
imposed upon the Class A Shares.
 
  For more information about the purchase of Class A Shares or reduced sales
charge programs, or to obtain the required application forms, call Nuveen toll-
free at (800) 257-8787.

Reduction or Elimination of Contingent Deferred Sales Charge
 
  Class A Shares are normally redeemed at net asset value, without any
Contingent Deferred Sales Charge ("CDSC"). However, in the case of Class A
Shares purchased at net asset value because the purchase amount exceeded $1
million, where the Authorized Dealer did not waive the sales commission, a CDSC
of 1% is imposed on any redemption within 18 months of purchase. In the case of
Class B Shares redeemed within six years of purchase, a CDSC is imposed,
beginning at 5% for redemptions within the first year, declining to 4% for
redemptions within years two and three, and declining by 1% each year
thereafter until disappearing after the sixth year. Class C Shares are redeemed
at net asset value, without any CDSC, except that a CDSC of 1% is imposed upon
redemption of Class C Shares that are redeemed within 12 months of purchase.
 
  In determining whether a CDSC is payable, the Fund will first redeem shares
not subject to any charge, or that represent an increase in the value of the
Fund account due to capital appreciation, and then will redeem shares held for
the longest period, unless the shareholder specifies another order. No CDSC is
charged on shares purchased as a result of automatic reinvestment of dividends
or capital gains paid. In addition, no CDSC will be charged on exchanges of
shares into another Nuveen Mutual Fund or Nuveen money market fund. The holding
period is calculated on a monthly basis and begins the first day of the month
in which the order for investment is received. The CDSC is calculated based on
the lower of the redeemed shares' cost or net asset value at the time of the
redemption and is deducted from the redemption proceeds. Nuveen receives the
amount of any CDSC shareholders pay. If Class A, Class B or Class C shares
subject to a CDSC are exchanged for shares of a Nuveen money market fund, the
CDSC would be imposed on the subsequent redemption of those money market fund
shares, and the period during which the shareholder holds the money market fund
shares would be counted in determining the remaining duration of the CDSC. The
Fund may elect not to so count the period during which the shareholder held the
money market fund shares, in which event the amount of any applicable CDSC
would be reduced in accordance with applicable SEC rules by the amount of any
12b-1 plan payments to which those money market funds shares may be subject.
 
  The CDSC may be waived or reduced under the following circumstances: (i) in
the event of total disability (as evidenced by a determination by the federal
Social Security Administration) of the shareholder (including a registered
joint owner) occurring after the purchase of the shares being redeemed; (ii) in
the event of the death of the shareholder (including a registered joint owner);
(iii) for redemptions made pursuant to a systematic withdrawal plan, up to 12%
annually of the current market value; (iv) involuntary redemptions caused by
operation of law; (v) redemptions in connection with a payment of account or
plan fees, (vi) redemptions in connection with the exercise of a reinstatement
privilege whereby the proceeds of a redemption of the Fund's shares subject to
a sales charge are reinvested in shares of certain funds within a specified
number of days; and (vii) redemptions in connection with the exercise of the
Fund's right to redeem all shares in an account that does not maintain a
certain minimum balance or the Board of Directors has determined may have
material adverse consequences to the shareholders of the Fund.
 
  In addition, the CDSC will be waived in connection with the following
redemptions of shares held by an employer-sponsored qualified defined
contribution retirement plan: (i) partial or complete redemptions in connection
with a distribution without penalty under Section 72(t) of the Internal Revenue
Code ("Code") from a retirement plan: (a) upon attaining age 59 1/2, (b) as
part of a series of substantially equal periodic payments, or (c) upon
separation from service and attaining age 55; (ii) partial or complete
redemptions in connection with a qualifying loan or hardship withdrawal; (iii)
complete redemptions in connection with termination of employment, plan
termination or transfer to another employer's plan or IRA; and (iv) redemptions
resulting from the return of an excess contribution. The CDSC will also be
waived in connection with the following redemptions of shares held in an IRA
account: (i) for redemptions made pursuant to an IRA systematic withdrawal
based on the shareholder's life expectancy including, but not limited to,
substantially
 
                                      S-45
<PAGE>
 
equal periodic payments described in Code Section 72(t)(A)(iv) prior to age 59;
and (ii) for redemption to satisfy required minimum distributions after age 70
from an IRA account (with the maximum amount subject to this waiver being based
only upon the shareholder's Nuveen IRA accounts).
 
Shareholder Programs
 
Exchange Privilege
 
  You may exchange shares of a class of the Fund for shares of the same class
of any other Nuveen Mutual Fund with reciprocal exchange privileges, at net
asset value without a sales charge, by sending a written request to the Fund,
c/o Nuveen Investor Services, P.O. Box 5186, Bowling Green Station, New York,
NY 10274-5186. Similarly, Class A, Class B, Class C and Class R Shares of other
Nuveen Mutual Funds may be exchanged for the same class of shares of the Fund
at net asset value without a sales charge. Exchanges of shares from any Nuveen
money market fund will be made into Class A Shares, Class B Shares, Class C
Shares or Class R Shares (if eligible) of the Fund at the public offering
price. If, however, a sales charge has previously been paid on the investment
represented by the exchanged shares (i.e., the shares to be exchanged were
originally issued in exchange for shares on which a sales charge was paid), the
exchange of shares from a Nuveen money market fund will be made into shares of
the Fund at net asset value. All share classes may be exchanged for shares of
any Nuveen money market fund.
 
  If you exchange shares subject to a CDSC, no CDSC will be charged at the time
of the exchange. However, if you subsequently redeem the shares acquired
through the exchange, the redemption may be subject to a CDSC, depending on
when you purchased your original shares and the CDSC schedule of the fund from
which you exchanged your shares.
 
  The shares to be purchased must be offered in your state of residence and you
must have held the shares you are exchanging for at least 15 days. The total
value of exchanged shares must at least equal the minimum investment
requirement of the Nuveen Mutual Fund being purchased. For federal income tax
purposes, any exchange constitutes a sale and purchase of shares and may result
in capital gain or loss. Before making any exchange, you should obtain the
Prospectus for the Nuveen Mutual Fund you are purchasing and read it carefully.
If the registration of the account for the Fund is not exactly the same as that
of the fund account from which the exchange is made, written instructions from
all holders of the account from which the exchange is being made must be
received, with signatures guaranteed by a member of an approved Medallion
Guarantee Program or in such other manner as may be acceptable to the Fund. You
may also exchange shares by telephone if you authorize telephone exchanges by
checking the applicable box on the Application Form or by calling Nuveen toll-
free at 800-257-8787 to obtain an authorization form. The exchange privilege
may be modified or discontinued by the Fund at any time.
 
  The exchange privilege is not intended to permit the Fund to be used as a
vehicle for short-term trading. Excessive exchange activity may interfere with
portfolio management, raise expenses, and otherwise have an adverse effect on
all shareholders. In order to limit excessive exchange activity and in other
circumstances where Fund management believes doing so would be in the best
interest of the Fund, the Fund reserves the right to revise or terminate the
exchange privilege, or limit the amount or number of exchanges or reject any
exchange. Shareholders would be notified of any such action to the extent
required by law.
 
Reinstatement Privilege
 
  If you redeemed Class A, Class B or Class C Shares of the Fund or any other
Nuveen Mutual Fund that were subject to a sales charge or a CDSC, you have up
to one year to reinvest all or part of the full amount of the redemption in the
same class of shares of the Fund at net asset value. This reinstatement
privilege can be
 
                                      S-46
<PAGE>
 
exercised only once for any redemption, and reinvestment will be made at the
net asset value next calculated after reinstatement of the appropriate class of
Fund shares. If you reinstate shares that were subject to a CDSC, your holding
period as of the redemption date also will be reinstated for purposes of
calculating a CDSC. The federal income tax consequences of any capital gain
realized on a redemption will not be affected by reinstatement, but a capital
loss may be disallowed in whole or in part depending on the timing, the amount
of the reinvestment and the fund from which the redemption occurred.
 
Fund DirectSM
 
  You can use Fund Direct to link your Fund account to your account at a bank
or other financial institution. Fund Direct enables you to transfer money
electronically between these accounts and perform a variety of account
transactions. These include purchasing shares by telephone, investing through a
Systematic Investment Plan, and sending dividends, distributions, redemption
payments or Systematic Withdrawal Plan payments directly to your bank account.
Please refer to the Application Form for details, or call Nuveen Investor
Services at 800-257-8787 for more information.
 
  Fund Direct privileges may be requested via an application you obtain by
calling 800-257-8787. Fund Direct privileges will apply to each shareholder
listed in the registration on your account as well as to your Authorized Dealer
representative of record unless and until Nuveen Investor Services receives
written instructions terminating or changing those privileges. After you
establish Fund Direct for your account, any change of bank account information
must be made by signature-guaranteed instructions to Nuveen Investor Services
signed by all shareholders who own the account.
 
  Purchases may be made by telephone only after your account has been
established. To purchase shares in amounts up to $250,000 through a telephone
representative, call Nuveen Investor Services at 800-257-8787. The purchase
payment will be debited from your bank account.
 
Redemption
 
  You may redeem shares by sending a written request for redemption directly to
the Fund, c/o Nuveen Investor Services, P.O. Box 5186, Bowling Green Station,
New York 10274-5186, accompanied by duly endorsed certificates, if issued.
Requests for redemption and share certificates, if issued, must be signed by
each shareholder and, if the redemption proceeds exceed $50,000 or are payable
other than to the shareholder of record at the address of record (which address
may not have changed in the preceding 60 days), the signature must be
guaranteed by a member of an approved Medallion Guarantee Program or in such
other manner as may be acceptable to the Fund. You will receive payment based
on the net asset value per share next determined after receipt by the Fund of a
properly executed redemption request in proper form. A check for the redemption
proceeds will be mailed to you within seven days after receipt of your
redemption request. For accounts registered in the name of a broker-dealer,
payment will be forwarded within three business days. However, if any shares to
be redeemed were purchased by check within 15 days prior to the date the
redemption request is received, the Fund will not mail the redemption proceeds
until the check received for the purchase of shares has cleared, which may take
up to 15 days.
 
Telephone and Electronic Redemptions
 
  If you have authorized telephone redemption and your account address has not
changed within the last 60 days, you can redeem shares that are held in non-
certificate form by calling Nuveen Investor Services at 800-257-8787. While you
or anyone authorized by you may make telephone redemption requests, redemption
 
                                      S-47
<PAGE>
 
checks will be issued only in the name of the shareholder of record and will be
mailed to the address of record. If your telephone request is received prior to
4:00 p.m. eastern time, the redemption check will normally be mailed the next
business day. For requests received after 4:00 p.m. eastern time, the
redemption will be effected at 4:00 p.m. eastern time the following business
day and the check will normally be mailed on the second business day after the
request.
 
  If you have authorized electronic fund redemption or established Fund Direct
privileges, you can take advantage of the following expedited redemption
procedures to redeem shares held in non-certificate form that are worth at
least $1,000. You may make electronic fund redemption requests through a phone
representative or Fund Direct redemption requests by calling Nuveen Investor
Services at 800-257-8787. If a redemption request is received by 4:00 p.m.
eastern time, the redemption will be made as of 4:00 p.m. that day. If the
redemption request is received after 4:00 p.m. eastern time, the redemption
will be made as of 4:00 p.m. the following business day. Proceeds of electronic
fund redemptions will normally be wired on the second business day following
the redemption, but may be delayed one additional business day if the Federal
Reserve Bank of Boston or the Federal Reserve Bank of New York is closed on the
day redemption proceeds would ordinarily be wired. The Fund reserves the right
to charge a fee for electronic fund redemption. Proceeds of redemptions through
Fund Direct will normally be wired to your Fund Direct bank account on the
second or third business day after the redemption.
 
  Before you may redeem shares electronically by phone or through Fund Direct,
you need to complete the telephone redemption authorization section of the
Application Form or the Fund Direct application form and return it to Nuveen
Investor Services. If you did not authorize telephone redemption when you
opened your account, you may obtain a telephone redemption authorization form
by writing the Fund or by calling Nuveen Investor Services toll-free at 800-
257-8787. Proceeds from electronic share redemptions will be transferred by
Federal Reserve wire only to the commercial bank account specified by the
shareholder on the Application Form. You need to send a written request to
Nuveen Investor Services in order to establish multiple accounts, or to change
the account or accounts designated to receive redemption proceeds. These
requests must be signed by each account owner with signatures guaranteed by a
member of an approved Medallion Guarantee Program or in such other manner as
may be acceptable to the Fund. Further documentation may be required from
corporations, executors, trustees or personal representatives.
 
  For the convenience of shareholders, the Fund has authorized Nuveen as its
agent to accept orders from financial advisers by wire or telephone for the
redemption of Fund shares. The redemption price is the first net asset value of
the appropriate share class determined following receipt of an order placed by
the financial adviser. The Fund makes payment for the redeemed shares to the
securities representatives who placed the order promptly upon presentation of
required documents with signatures guaranteed as described above. Neither the
Fund nor Nuveen charges any redemption fees other than any CDSC as described
above. However, your financial adviser may charge you for serving as agent in
the redemption of shares.
 
  The Fund reserves the right to refuse telephone redemptions and, at its
option, may limit the timing, amount or frequency of these redemptions.
Telephone redemption procedures may be modified or terminated at any time, on
30 days' notice, by the Fund. The Fund, Chase Global Funds Services Company,
the Funds' shareholder services agent ("Chase Global"), and Nuveen will not be
liable for following telephone instructions reasonably believed to be genuine.
The Fund employs procedures reasonably designed to confirm that telephone
instructions are genuine. These procedures include recording all telephone
instructions and requiring up to three forms of identification prior to acting
upon a caller's instructions. If the Fund does not follow reasonable procedures
for protecting shareholders against loss on telephone transactions, it may be
liable for any losses due to unauthorized or fraudulent telephone instructions.

APPENDIX A
 
RATINGS OF INVESTMENTS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group ("S&P") rating symbols and their meanings (as
published by S&P) follows:
 
                                 LONG TERM DEBT
 
  An S&P corporate or municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers,
or lessees.
 
  The debt rating is not a recommendation to purchase, sell, or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor.
 
  The ratings are based on current information furnished by the issuer or
obtained by S&P from other sources it considers reliable. S&P does not perform
an audit in connection with any rating and may, on occasion, rely on unaudited
financial information. The ratings may be changed, suspended, or withdrawn as a
result of changes in, or unavailability of, such information, or based on other
circumstances.
 
  The ratings are based, in varying degrees, on the following considerations:
 
    1. Likelihood of default--capacity and willingness of the obligor as to
  the timely payment of interest and repayment of principal in accordance
  with the terms of the obligation;
 
    2. Nature of and provisions of the obligation;
 
    3. protection afforded by, and relative position of, the obligation in
  the event of bankruptcy, reorganization, or other arrangement under the
  laws of bankruptcy and other laws affecting creditors' rights.
 
INVESTMENT GRADE
 
AAA  Debt rated 'AAA' has the highest rating assigned by S&P. Capacity to pay
     interest and repay principal is extremely strong.
 
AA   Debt rated 'AA' has a very strong capacity to pay interest and repay
     principal, and differs from the highest-rated issues only in small
     degree.
 
A    Debt rated 'A' has a strong capacity to pay interest and repay principal
     although it is somewhat more susceptible to the adverse effects of
     changes in circumstances and economic conditions than debt in higher-
     rated categories.
 
BBB  Debt rated 'BBB' is regarded as having an adequate capacity to pay
     interest and repay principal. Whereas it normally exhibits adequate
     protection parameters, adverse economic conditions or changing
     circumstances are more likely to lead to a weakened capacity to pay
     interest and repay principal for debt in this category than in higher-
     rated categories.
 
SPECULATIVE GRADE RATING
 
  Debt rated 'BB,' 'B,' 'CCC,' 'CC' and 'C' is regarded as having predominantly
speculative characteristics, with respect to capacity to pay interest and repay
principal. 'BB' indicates the least degree of speculation and 'C' the highest.
While such debt will likely have some quality and protective characteristics
these are outweighed by major uncertainties or major exposures to adverse
conditions.
 
BB  Debt rated 'BB' has less near-term vulnerability to default than other
    speculative issues. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which
 
                                      A-1
<PAGE>
 
     could lead to inadequate capacity to meet timely interest and principal
     payments. the 'BB' rating category is also used for debt subordinated to
     senior debt that is assigned an actual or implied 'BBB-' rating.
 
B    Debt rated 'B' has a greater vulnerability to default but currently has
     the capacity to meet interest payments and principal repayments. Adverse
     business, financial, or economic conditions will likely impair capacity
     or willingness to pay interest and repay principal.
 
     The 'B' rating category is also used for debt subordinated to senior debt
     that is assigned an actual or implied 'BB' or 'BB-' rating.
 
CCC  Debt rated 'CCC' has a currently identifiable vulnerability to default
     and is dependent upon favorable business, financial, and economic
     conditions to meet timely payment of interest and repayment of principal.
     In the event of adverse business, financial, or economic conditions, it
     is not likely to have the capacity to pay interest and repay principal.
 
     The 'CCC' rating category is also used for debt subordinated to senior
     debt that is assigned an actual or implied 'B' or 'B-' rating.
 
CC   The rating 'CC' typically is applied to debt subordinated to senior debt
     that is assigned an actual or implied 'CCC' debt rating.
 
C    The rating 'C' typically is applied to debt subordinated to senior debt
     which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating
     may be used to cover a situation where a bankruptcy petition has been
     filed, but debt service payments are continued.
 
CI   The rating 'CI' is reserved for income bonds on which no interest is
     being paid.
 
D    Debt rated 'D' is in payment default. The 'D' rating category is used
     when interest payments or principal payments are not made on the date due
     even if the applicable grace period has not expired, unless S&P believes
     that such payments will be made during such grace period. The 'D' rating
     also will be used upon the filling of a bankruptcy petition if debt
     service payments are jeopardized.
 
     Plus (+) or Minus (-): the ratings from 'AA' to 'CCC' may be modified by
     the addition of a plus or minus sign to show relative standing within the
     major rating categories.
 
     Provisional Ratings: the letter "p" indicates that the rating is
     provisional. A provisional rating assumes the successful completion of
     the project financed by the debt being rated and indicates that payment
     of debt service requirements is largely or entirely dependent upon the
     successful and timely completion of the project. This rating, however,
     while addressing credit quality subsequent to completion of the project,
     makes no comment on the likelihood of, or the risk of default upon
     failure of, such completion. The investor should exercise judgment with
     respect to such likelihood and risk.
 
L    The letter 'L' indicates that the rating pertains to the principal amount
     of those bonds to the extent that the underlying deposit collateral is
     federally insured by the Federal Savings & Loan Insurance Corp. or the
     Federal Deposit Insurance Corp.* and interest is adequately
     collateralized. In the case of certificates of deposit, the letter "L'
     indicates that the deposit, combined with other deposits being held in
     the same right and capacity, will be honored for principal and accrued
     pre-default interest up to the federal insurance limits within 30 days
     after closing of the insured institution or, in the event that the
     deposit is assumed by a successor insured institution, upon maturity.
 
NR   Indicates no rating has been requested, that there is insufficient
     information on which to base a rating, or that S&P does not rate a
     particular type of obligation as a matter of policy.
 
 
                                      A-2
<PAGE>
 
                                COMMERCIAL PAPER
 
  An S&P commercial paper rating is a current assessment of the likelihood of
timely payment of debt having an original maturity of no more than 365 days.
 
  Ratings are graded into several categories, ranging from "A-1" for the
highest quality obligations to "D" for the lowest. These categories are as
follows:
 
A-1  This designation indicates that the degree of safety regarding timely
     payment is strong. Those issues determined to possess extremely strong
     safety characteristics are denoted with a plus sign (+) designation.
 
A-2  Capacity for timely payment on issues with this designation is
     satisfactory. However, the relative degree of safety is not as high as
     for issues designated "A-1."
 
A-3  Issues carrying this designation have adequate capacity for timely
     payment. They are, however, somewhat more vulnerable to the adverse
     effects of changes in circumstances than obligations carrying the higher
     designations.
 
B    Issues rated "B" are regarded as having only speculative capacity for
     timely payment.
 
C    This rating is assigned to short-term debt obligations with a doubtful
     capacity for payment.
 
D    Debt rated "D" is in payment default. The "D" rating category is used
     when interest payments or principal payments are not made on the date
     due, even if the applicable grace period has not expired, unless S&P
     believes that such payments will be made during such grace period.
 
  A commercial rating is not a recommendation to purchase, sell, or hold a
security inasmuch as it does not comment as to market price or suitability for
a particular investor. The ratings are based on current information furnished
to S&P by the issuer or obtained by S&P from other sources it considers
reliable. S&P does not perform an audit in connection with any rating and may,
on occasion, rely on unaudited financial information. the ratings may be
changed, suspended, or withdrawn as a result of changes in or unavailability of
such information or based on other circumstances.
 
  MOODY'S INVESTORS SERVICE, INC.--A brief description of the applicable
Moody's Investors Service, Inc. ("Moody's") rating symbols and their meanings
(as published by Moody's) follows:
 
                                 LONG TERM DEBT
 
Aaa  Bonds which are rated Aaa are judged to be of the best quality. They
     carry the smallest degree of investment risk and are generally referred
     to as "gilt edge." Interest payments are protected by a large or by an
     exceptionally stable margin and principal is secure. While the various
     protective elements are likely to change, such changes as can be
     visualized are mostly unlikely to impair the fundamentally strong
     position of such issues.
 
Aa   Bonds which are rated Aa are judged to be of high quality by all
     standards. Together with the Aaa group they comprise what are generally
     known as high grade bonds. They are rated lower than the best bonds
     because margins of protection may not be as large as in Aaa securities or
     fluctuation of protective elements may be of greater amplitude or there
     may be other elements present which make the long-term risks appear
     somewhat larger than in Aaa securities.
 
A    Bonds which are rated A possess many favorable investment attributes and
     are to be considered as upper medium grade obligations. Factors giving
     security to principal and interest are considered adequate, but elements
     may be present which suggest a susceptibility to impairment sometime in
     the future.
 
Baa  Bonds which are rated Baa are considered as medium grade obligations,
     i.e., they are neither highly protected nor poorly secured. Interest
     payments and principal security appear adequate for the present,
 
                                      A-3
<PAGE>
 
     but certain protective elements may be lacking or may be
     characteristically unreliable over any great length of time. Such bonds
     lack outstanding investment characteristics and in fact have speculative
     characteristics as well.
 
Ba   Bonds which are rated Ba are judged to have speculative elements; their
     future can not be considered as well assured. Often the protection of
     interest and principal payments may be very moderate and thereby, not
     well safeguarded during both good and bad times over the future.
     Uncertainty of position characterizes bonds in this class.
 
B    Bonds which are rated B generally lack characteristics of the desirable
     investment. Assurance of interest and principal payments or of
     maintenance of other terms of the contract over any long period of time
     may be small.
 
Caa  Bonds which are rated Caa are of poor standing. Such issues may be in
     default, or there may be present elements of danger with respect to
     principal or interest.
 
Ca   Bonds which are rated Ca represent obligations which are speculative in a
     high degree. Such issues are often in default or have other marked
     shortcomings.
 
C    Bonds which are rated C are the lowest rated class of bonds, and issues
     so rated can be regarded as having extremely poor prospects of ever
     attaining any real investment standing.
 
     Bonds for which the security depends upon the completion of some act or
     the fulfillment of some condition are rated conditionally. These are
     bonds secured by (a) earnings of projects under construction, (b)
     earnings of projects unseasoned in operation experience, (c) rentals
     which begin when facilities are completed, or (d) payments to which some
     other limiting condition attaches. Parenthetical rating denotes probable
     credit stature upon completion of construction or elimination of basis of
     condition.
 
NOTE: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
      possess the strongest investment attributes are designated by the symbols
      Aa1, A1, Baa1, Ba1, and B1.
 
                                COMMERCIAL PAPER
 
  Issuers rated PRIME-1 (or related supporting institutions) have a superior
capacity for repayment of senior short-term promissory obligations. Prime-1
repayment capacity will often be evidenced by many of the following
characteristics:
 
  -- Leading market positions in well-established industries.
 
  -- High rates of return on funds employed.
 
  -- Conservative capitalization structure with moderate reliance on debt and
  ample asset protection.
 
  -- Broad margins in earnings coverage of fixed financial charges and high
  internal cash generation.
 
  -- Well-established access to a range of financial markets and assured
  sources of alternate liquidity.
 
  Issuers rated PRIME-2 (or related supporting institutions) have a strong
capacity for repayment of senior short-term promissory obligations. This will
normally be evidenced by many of the characteristics cited above but to a
lesser degree. Earnings trends and coverage ratios, while sound, may be more
subject to variation. Capitalization characteristics, while still appropriate,
may be more affected by external conditions. Ample alternate liquidity is
maintained.
 
  Issuers rated PRIME-3 (or related supporting institutions) have an acceptable
capacity for repayment of senior short-term promissory obligations. The effect
of industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial
leverage.
 
                                      A-4
<PAGE>
 
  Issuers rated NOT PRIME do not fall within any of the Prime rating
categories.
 
  DUFF & PHELPS, INC.--A brief description of the applicable Duff & Phelps,
Inc. ("D&P") ratings symbols and their meanings (as published by D&P) follows:
 
                                 LONG TERM DEBT
 
  These ratings represent a summary opinion of the issuer's long-term
fundamental quality. Rating determination is based on qualitative and
quantitative factors which may vary according to the basic economic and
financial characteristics of each industry and each issuer. Important
considerations are vulnerability to economic cycles as well as risks related to
such factors as competition, government action, regulation, technological
obsolescence, demand shifts, cost structure, and management depth and
expertise. The projected viability of the obligor at the trough of the cycle is
a critical determination.
 
  Each rating also takes into account the legal form of the security, (e.g.,
first mortgage bonds, subordinated debt, preferred stock, etc.). The extent of
rating dispersion among the various classes of securities is determined by
several factors including relative weightings of the different security classes
in the capital structure, the overall credit strength of the issuer, and the
nature of covenant protection.
 
  The Credit Rating Committee formally reviews all ratings once per quarter
(more frequently, if necessary). Ratings of 'BBB-' and higher fall within the
definition of investment grade securities, as defined by bank and insurance
supervisory authorities. Structured finance issues, including real estate,
asset-backed and mortgage-backed financings, use this same rating scale. Duff &
Phelps Credit Rating claims paying ability ratings of insurance companies use
the same scale with minor modification in the definitions. Thus, an investor
can compare the credit quality of investment alternatives across industries and
structural types. A "Cash Flow Rating" (as noted for specific ratings)
addresses the likelihood that aggregate principal and interest will equal or
exceed the rated amount under appropriate stress conditions.

                            SHORT-TERM DEBT RATINGS
 
  Duff & Phelps' short-term ratings are consistent with the rating criteria
used by money market participants. The ratings apply to all obligations with
maturities of under one year, including commercial paper, the uninsured portion
of certificates of deposit, unsecured bank loans, master notes, bankers
acceptances, irrevocable letters of credit, and current maturities of long-term
debt. Asset-backed commercial paper is also rated according to this scale.
 
  Emphasis is placed on liquidity which is defined as not only cash from
operations but also access to alternative sources of funds including trade
credit, bank lines, and the capital markets. An important consideration is the
level of an obligor's reliance on short-term funds on an ongoing basis.
 
  The distinguishing feature of Duff & Phelps Credit Ratings' short-term
ratings is the refinement of the traditional '1' category. The majority of
short-term debt issuers carry the highest rating, yet quality differences exist
within that tier. As a consequence, Duff & Phelps Credit Rating has
incorporated gradations of '1+' (one plus) and '1-' (one minus) to assist
investors in recognizing those differences.
 
  These ratings are recognized by the SEC for broker-dealer requirements,
specifically capital computation guidelines. These ratings meet Department of
labor ERISA guidelines governing pension and profit-sharing investments. State
regulators also recognize the ratings of Duff & Phelps Credit Rating for
insurance company investment portfolios.

 D-1+   HIGH GRADE
        Highest certainty of timely payment. Short-term liquidity, including
        internal operating factors and/or access to alternative sources of

  FITCH INVESTORS SERVICE, INC.--A brief description of the applicable Fitch
Investors Service, Inc. ("Fitch") ratings symbols and meanings (as published by
Fitch) follows:
 
                                 LONG TERM DEBT
 
  Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.
 
  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength and credit quality.
 
  Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guaranties unless otherwise indicated.
 
  Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
  Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.
 
  Fitch ratings are based on information obtained from issuers, other obligors,
underwriters, their experts, and other sources Fitch believes to be reliable.
Fitch does not audit or verify the truth or accuracy of such information.
Ratings may be changed, suspended or withdrawn as a result of changes in, or
the unavailability of, information or for other reasons.
 
<TABLE>
 <C> <S>
 AAA Bonds considered to be investment grade and of the highest credit quality.
     The obligor has an exceptionally strong ability to pay interest and repay
     principal, which is unlikely to be affected by reasonably foreseeable
     events.
 AA  Bonds considered to be investment grade and of very high credit quality.
     The obligor's ability to pay interest and repay principal is very strong,
     although not quite as strong as bonds rated 'AAA'. Because bonds rated in
     the 'AAA' and 'AA' categories are not significantly vulnerable to
     foreseeable future developments, short-term debt of the issuers is
     generally rated 'F-1+'.
</TABLE>
 
                                      A-7
<PAGE>
 
<TABLE>
 <C> <S>
 A   Bonds considered to be investment grade and of high credit quality. The
     obligor's ability to pay interest and repay principal is considered to be
     strong but may be more vulnerable to adverse changes in economic
     conditions and circumstances than bonds with higher ratings.
 BBB Bonds considered to be investment grade and of satisfactory credit
     quality. The obligor's ability to pay interest and repay principal is
     considered to be adequate. Adverse changes in economic conditions and
     circumstances, however, are more likely to have adverse impact on these
     bonds and, therefore, impair timely payment. The likelihood that the
     ratings of these bonds will fall below investment grade is higher than for
     bonds with higher ratings.
</TABLE>
 
  Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
('BB' to 'C') represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ('DDD' to 'D') is an
assessment of the ultimate recovery value through reorganization or
liquidation.
 
  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength.
 
  Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories can not fully reflect the
differences in the degrees of credit risk.
 
<TABLE>
 <C>   <S>
 BB    Bonds are considered speculative. The obligor's ability to pay interest
       and repay principal may be affected over time by adverse economic
       changes. However, business and financial alternatives can be identified
       which could assist the obligor in satisfying its debt service
       requirements.
 B     Bonds are considered highly speculative. While bonds in this class are
       currently meeting debt service requirements, the probability of
       continued timely payment of principal and interest reflects the
       obligor's limited margin of safety and the need for reasonable business
       and economic activity throughout the life of the issue.
 CCC   Bonds have certain identifiable characteristics which, if not remedied,
       may lead to default. The ability to meet obligations requires an
       advantageous business economic environment.
 CC    Bonds are minimally protected. Default in payment of interest and/or
       principal seems probable over time.
 C     Bonds are in imminent default in payment of interest or principal.
 DDD,  Bonds are in default on interest and/or principal payments. Such bonds
 DD    are extremely speculative and should be valued on the basis of their
 AND D ultimate recovery value in liquidation or reorganization of the obligor.
       'DDD' represents the highest potential for recovery of these bonds, and
       'D' represents the lowest potential for recovery.
</TABLE>
 
                               SHORT-TERM RATINGS
 
  Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally up to three years, including
commercial paper, certificate of deposit, medium-term notes, and municipal and
investment notes.
 
                                      A-8

  The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.
 
<TABLE>
 <C>  <S>
 F-1+ EXCEPTIONALLY STRONG CREDIT QUALITY Issues assigned this rating are
      regarded as having the strongest degree of assurance for timely payment.
 F-1  VERY STRONG CREDIT QUALITY Issues assigned this rating reflect an
      assurance of timely payment only slightly less in degree than issues
      rated 'F-1+'.
 F-2  GOOD CREDIT QUALITY Issues assigned this rating have a satisfactory
      degree of assurance for timely payment, but the margin of safety is not
      as great as for issues assigned 'F-1+' and 'F-1' ratings.
 F-3  FAIR CREDIT QUALITY Issues assigned this rating have characteristics
      suggesting that the degree of assurance for timely payment is adequate;
      however, near-term adverse changes could cause these securities to be
      rated below investment grade.
 F-S  WEAK CREDIT QUALITY Issues assigned this rating have characteristics
      suggesting a minimal degree of assurance for timely payment and are
      vulnerable to near-term adverse changes in financial and economic
      conditions.
 D    DEFAULT Issues assigned this rating are in actual or imminent payment
      default.
 LOC  The symbol LOC indicates that the rating is based on a letter of credit
      issued by a commercial bank.
