                       INVESTMENT OBJECTIVES AND POLICIES

                                    BOND FUND

     Bond  Fund's  investment  objective  is to  provide a high level of current
income  consistent  with  preservation  of capital.  Such  objective  may not be
changed without shareholder approval. There can be no assurance that Bond Fund's
investment objective will be attained.

     Bond Fund pursues its  objective by  investing  primarily in a  diversified
portfolio  of  investment  grade  bonds and other  debt  securities  of  similar
quality.  Investment grade securities are those securities rated within the four
highest  grades  assigned by Moody's  Investors  Service,  Inc.  ("Moody's")  or
Standard & Poor's Corporation ("S&P").

   
     Bond  Fund may also  invest  in below  investment  grade  securities.  Such
securities are commonly  referred to as junk bonds.  Bond Fund currently intends
to limit such  investments  to 15% of its total assets and not to invest in junk
bonds  rated lower than B by Moody's or S&P.  Securities  rated in the medium to
lower  rating  of  categories  of  nationally   recognized   statistical  rating
organizations  and unrated  securities of comparable  quality are  predominately
speculative  with respect to the capacity to pay interest and repay principal in
accordance  with the  terms of the  security  and  generally  involve  a greater
volatility of price than securities in higher rating categories. See "Investment
Objectives  and  Policies"  in  the  Statement  of  Additional  Information  for
additional information regarding ratings of debt securities.  In purchasing such
securities,  Bond Fund will rely on IAI's  judgment,  analysis and experience in
evaluating the  creditworthiness of an issuer of such securities.  IAI will take
into consideration,  among other things, the issuer's financial  resources,  its
sensitivity  to economic  conditions  and trends,  its  operating  history,  the
quality  of the  issuer's  management  and  regulatory  matters.  Please see the
section  "Additional  Information" for further information on the credit quality
of securities owned by Bond Fund.
    

     Other debt  securities in which Bond Fund may invest  include,  but are not
limited to, securities of, or guaranteed by, the United States  Government,  its
agencies  or   instrumentalities,   bank   certificates  of  deposit,   bankers'
acceptances,  debt securities of foreign issuers,  and commercial paper rated at
least Prime-2 by Moody's or A-2 by S&P or otherwise  issued by companies  having
an outstanding  unsecured debt issue  currently  rated A or better by Moody's or
S&P. Bond Fund may also invest in U.S. Treasury inflation-protection securities.
The value of such inflation-protection  securities is adjusted for inflation and
periodic  interest  payments are in amounts  equal to a fixed  percentage of the
inflation-adjusted  value of the principal.  Under normal market conditions,  at
least 65% of Bond Fund's total assets will be invested in debt  obligations  and
government  securities with maturities at the time of acquisition of one year or
more.

     Although  Bond Fund  generally  will not make  direct  purchases  of common
stock,  Bond  Fund may  purchase  preferred  stock and  convertible  securities.
Preferred  stock are  securities  that the represent an ownership  interest in a
corporation  and that  give the owner a prior  claim  over  common  stock on the
company's  earnings or assets.  Convertible  securities are debt  obligations of
corporations  convertible  into or  exchangeable  for equity  securities or debt
obligations  that  carry with them the right to acquire  equity  securities,  as
evidenced by warrants attached to such securities,  or acquired as part of units
of the  securities.  The risks  associated with investing in preferred stock and
convertible  securities are different from those  traditionally  associated with
investments  in debt  securities.  Such risks are  similar  instead to the risks
associated with  investments in equity  securities,  including the risk that the
value of the equity security will fluctuate in response to the activities of the
issuing  company or in response to general  market and/or  economic  conditions.
Bond Fund will limit its  investments in such  securities to a maximum of 10% of
its net assets.

     Bond Fund may  invest in  securities  issued by  foreign  issuers,  whether
dollar-denominated  or not, including  securities issued or guaranteed by one or
more foreign  governments or any of their  political  subdivisions,  agencies or
instrumentalities,  including  obligations of supranational  entities,  that are
determined by IAI to be of comparable  quality to the other obligations in which
Bond Fund may invest.  Bond Fund currently intends to invest no more than 25% of
the value of its total assets in  non-dollar  denominated  securities of foreign
issuers.

     Bond Fund may employ certain other investment  techniques,  as described in
the  section  "Other  Fund  Investment  Techniques."  Please see the  Prospectus
section "Fund Risk Factors" and the Statement of Additional  Information section
"Investment  Objectives  and Policies" for a discussion of the risks  associated
with investing in Bond Fund.

                                 GOVERNMENT FUND

     The investment  objectives of Government  Fund are to provide  shareholders
with a high level of current income and with preservation of capital. In seeking
to achieve its objectives,  Government Fund will invest its assets  primarily in
securities issued, guaranteed or collateralized by the United States Government,
its agencies or  instrumentalities  whether or not backed by the "full faith and
credit"  pledge of the United States  Government  and in  repurchase  agreements
pertaining  to such  securities.  Such  securities  may  include  U.S.  Treasury
inflation-protection   securities.   The  value  of  such   inflation-protection
securities  is adjusted  for  inflation  and periodic  interest  payments are in
amounts  equal  to a fixed  percentage  of the  inflation-adjusted  value of the
principal.  IAI anticipates  that each of Government  Fund's  objectives will be
given  approximately  equal  consideration in the selection of Fund investments.
Government Fund's investment  objectives may not be changed without  shareholder
approval. There can be no assurance that Government Fund's investment objectives
will be attained.

     Under normal market conditions, Government Fund will invest at least 65% of
its total assets in  securities  issued,  guaranteed  or  collateralized  by the
United States  Government,  its agencies or  instrumentalities  (excluding,  for
purposes of calculating this minimum, CMOs as described below, which are secured
by obligations of the U.S. Government, its agencies or instrumentalities but are
issued by private issuers), including:


     1. United States Treasury  obligations,  such as Treasury Bills (which have
original  maturities of one year or less),  Treasury  Notes (which have original
maturities  of one  to ten  years)  and  Treasury  Bonds  (which  have  original
maturities generally greater than ten years);

     2. Obligations of United States Government  agencies and  instrumentalities
which are  secured by the full faith and credit of the United  States  Treasury,
such  as  Government  National  Mortgage  Association  ("Ginnie  Mae")  modified
pass-through certificates;

     3. Obligations  which are secured by the right of the issuer to borrow from
the United States Treasury,  such as securities  issued by the Federal Financing
Bank or the United States Postal Service; and

     4. Obligations  which are supported by the credit of the government  agency
or  instrumentality  itself  (but are not backed by the full faith and credit of
the United  States  Government)  such as  securities  of the  Federal  Home Loan
Mortgage   Corporation   ("Freddie  Mac")  or  the  Federal  National   Mortgage
Association ("Fannie Mae"), including pass-through  securities and participation
certificates thereof.

                                      7
<PAGE>


     Guarantees as to the timely payment of principal and interest do not extend
to the  value or yield of such  securities  nor do they  extend  to the value of
Government  Fund's shares.  In the case of securities in which  Government  Fund
invests that are not backed by the "full faith and credit" of the United  States
Government,  the  investor  must  look  principally  to the  agency  issuing  or
guaranteeing the obligation for ultimate repayment and may not be able to assert
a claim against the United States  Government  itself in the event the agency or
instrumentality  does not meet its commitment.  Except as specifically set forth
below, there are no percentage limitations with regard to the purchase of any of
Government Fund's investments.

     The  dollar-weighted  average maturity of Government  Fund's portfolio will
generally  not  exceed,  and may be  substantially  less  than,  ten  years.  As
discussed below, mortgage-related securities generally have an average life less
than their  maturity.  Because of  variations in  prepayment  rights,  it is not
possible  to  accurately  predict  the  life  of a  particular  mortgage-related
investment.  For purposes of determining the dollar-weighted average maturity of
Government Fund's portfolio, IAI will consider the statistical average remaining
life of mortgage-related securities.

     The mortgage-related securities in which Government Fund may invest include
pass-through   securities.   Mortgage  pass-through  securities  are  issued  by
government  agencies  such as Ginnie  Mae,  Freddie  Mac and  Fannie  Mae.  Such
securities are formed when mortgages are pooled together and undivided interests
in the  pool  are  sold to  investors  (such  as  Government  Fund)  by  various
governmental  and  government-related  organizations.  The  cash  flow  from the
underlying mortgages is "passed through" to the holders of the securities in the
form of monthly payments of interest, principal and prepayments.  Timely payment
of the  principal and interest on such  securities  is guaranteed  either by the
full faith and credit of the United States  Government (as in the case of Ginnie
Mae  securities)  or by the agency  itself  (as in the case of  Freddie  Mac and
Fannie Mae securities). In addition, Government Fund may invest up to 35% of its
assets in  securities  of private  issuers that are  collateralized  by pools of
mortgages issued or guaranteed by the United States Government,  its agencies or
instrumentalities,  called collateralized mortgage obligations ("CMOs"). CMOs of
private issuers,  even though collateralized by Government  securities,  are not
guaranteed by the U.S.  Government or any agency or  instrumentality of the U.S.
Government.  Government Fund will invest in privately  issued CMOs only if rated
at the time of investment Aaa by Moody's Investors Service, Inc. ("Moody's"), or
AAA by Standard & Poor's Corporation  ("S&P").  CMOs are more fully described in
the  Statement  of  Additional  Information  under  "Investment  Objectives  and
Policies--Mortgage-Backed Securities."

     The average life of such mortgage pools varies with the maturities of
the underlying mortgage instruments. In addition, a pool's term may be shortened
by  unscheduled  or early  payments of principal and interest on the  underlying
mortgages.  The  occurrence  of  mortgage  prepayment  is  affected  by  factors
including the level of interest rates, general economic conditions, the location
and  age  of  the  mortgage  and  other  social  and   demographic   conditions.
Accordingly, the life of an individual mortgage-related security is likely to be
substantially  shorter  than  the  stated  maturity  of  the  mortgages  in  the
underlying  pool.  Yields on  mortgage-related  securities are typically  quoted
based on the maturity of the underlying  instruments and the associated  average
life assumption. Actual prepayment experience may cause the yield to differ from
the assumed average life yield. See the Statement of Additional  Information for
more information about the characteristics of these instruments.

     Instrumentalities  of the United States Government which issue or guarantee
securities in which Government Fund may invest include,  but are not limited to,
the Federal Farm Credit System, the Student Loan Marketing Association,  Federal
Home Loan  Banks,  Federal  Land Banks,  Freddie  Mac and Fannie Mae.  Since the
United States  Treasury is not obligated by law to provide support to all United
States Government instrumentalities and agencies, Government Fund will invest in
securities  issued  by  such   instrumentalities  and  agencies  only  when  IAI
determines  that the credit risk with respect to the  instrumentality  or agency
does not make its securities unsuitable investments for Government Fund.

                                      8
<PAGE>


     Government  Fund may also  invest in  non-U.S.  Government  bonds and other
fixed income securities including fixed income securities issued by corporations
and foreign entities,  whether  dollar-denominated  or not, securities issued or
guaranteed  by one or  more  foreign  governments  or  any  of  their  political
subdivisions,  agencies or  instrumentalities,  and obligations of supranational

determined by IAI to be of comparable quality.  For a description of Moody's and
S&P ratings, see Appendix A to the Statement of Additional Information.

     Government  Fund  may  employ  certain  other  investment  techniques,   as
described  in the section  "Other Fund  Investment  Techniques."  Please see the
Prospectus   section  "Fund  Risk  Factors"  and  the  Statement  of  Additional
Information section "Investment Objectives and Policies" for a discussion of the
risks associated with investing in Government Fund.

OTHER FUND INVESTMENT TECHNIQUES

REPURCHASE AGREEMENTS

     Each Fund is permitted  to invest in  repurchase  agreements.  A repurchase
agreement is a contract by which a Fund  acquires  the  security  ("collateral")
subject to the  obligation of the seller to  repurchase  the security at a fixed
price and date (within seven days). A repurchase agreement may be construed as a
loan under  relevant law. The Funds may enter into  repurchase  agreements  with
respect  to  any  securities  which  they  may  acquire  consistent  with  their
investment  policies  and  restrictions.  The  Funds'  custodian  will  hold the
securities  underlying  any  repurchase  agreement in a segregated  account.  In
investing in repurchase agreements, the Funds' risk is limited to the ability of
the  seller  to pay the  agreed-upon  price at the  maturity  of the  repurchase
agreement. In the opinion of IAI, such risk is not material,  since in the event
of default, barring extraordinary circumstances,  the Funds would be entitled to
sell the underlying  securities or otherwise  receive adequate  protection under
federal bankruptcy laws for their interest in such securities.  However,  to the
extent that proceeds  from any sale upon a default are less than the  repurchase
price,  the Funds could suffer a loss. In addition,  the Funds may incur certain
delays in obtaining direct ownership of the collateral.

WHEN-ISSUED/DELAYED DELIVERY TRANSACTIONS

     Each Fund may purchase  securities on a "when-issued"  or delayed  delivery
basis and purchase or sell securities on a "forward commitment" basis. When such
transactions  are  negotiated,  the price is fixed at the time the commitment is
made,  but delivery and payment for the  securities  take place at a later date.
Normally,  the settlement  date occurs within two months after the  transaction,
but delayed settlements beyond two months may be negotiated.  At the time a Fund
enters into a  transaction  on a  when-issued  or forward  commitment  basis,  a
segregated  account  consisting  of  cash,   government   securities  or  liquid
high-grade  debt  securities  equal to the value of the  when-issued  or forward
commitment  securities will be established and maintained with the custodian and
will be marked to the market daily.  During the period  between a commitment and
settlement, no payment is made for the securities and, thus, no interest accrues
to the  purchaser  from the  transaction.  If a Fund  disposes  of the  right to
acquire a when-issued security prior to its acquisition or disposes of its right
to deliver or receive against a forward commitment,  it can incur a gain or loss
due to market  fluctuation.  The use of  when-issued  transactions  and  forward
commitments  enables a Fund to hedge  against  anticipated  changes in  interest
rates and  prices.  A Fund may also enter  into such  transactions  to  generate
incremental income. In some instances,  the third-party seller of when-issued or
forward commitment securities may determine prior to the settlement date that it
will be unable or unwilling to meet its existing transaction commitments without
borrowing securities.  If advantageous from a yield perspective,  a Fund may, in
that event, agree to resell its purchase commitment to the third-party seller at
the current market price on the date of sale and concurrently enter into another
purchase  commitment for such securities at a later date. As an inducement for a
Fund to "roll over" its  purchase  commitment,  a Fund may receive a  negotiated
fee.  As to each Fund,  no more than 20% of its net assets  may be  invested  in
when-issued,  delayed delivery or forward commitment  transactions,  and of such
20%,  no more than  one-half  (i.e.,  10% of its net  assets) may be invested in
when-issued,  delayed delivery or forward  commitment  transactions  without the
intention  of  actually  acquiring  securities  (i.e.,  dollar  rolls or  "roll"
transactions).  For additional information on roll transactions, see "Investment

                                      9
<PAGE>

Objectives  and  Policies  --  Dollar  Rolls"  in the  Statement  of  Additional
Information.

ILLIQUID SECURITIES

     Each Fund may  invest up to 15% of its net  assets in  securities  that are
considered  illiquid because of the absence of a readily available market or due
to legal or contractual  restrictions.  However,  certain restricted  securities
that are not registered for sale to the general public but that can be resold to
institutional  investors may be considered liquid pursuant to guidelines adopted
by the Board of Directors.  The institutional  trading market is relatively new,
and the liquidity of a Fund's  investments could be impaired if trading does not
develop or declines.

ZERO COUPON OBLIGATIONS

     Each Fund may also invest in zero coupon obligations of the U.S. Government
or its agencies,  tax exempt issuers and corporate issuers,  including rights to
stripped coupon and principal payments ("STRIPS"). Zero coupon bonds do not make
regular interest payments;  rather, they are sold at a discount from face value.
Principal and accreted discount (representing interest accrued but not paid) are
paid at maturity. STRIPS are debt securities that are stripped of their interest
after the  securities  are issued,  but otherwise are  comparable to zero coupon
bonds. The market values of strips and zero coupon bonds generally  fluctuate in
response   to  changes  in   interest   rates  to  a  greater   degree  than  do
interest-paying securities of comparable term and quality.

MORTGAGE-BACKED SECURITIES

     Each Fund may invest in pass-through  securities  which are sold by various
private,   governmental  and  government-related   organizations.   Pass-through
securities  are formed  when  mortgages  and other debt  instruments  are pooled
together and undivided  interests in the pool are sold to investors  such as the
Funds. The cash flow from the underlying debt instruments is "passed through" to
the  holders  of the  securities  in the form of  periodic  (generally  monthly)
payments of interest,  principal  and  prepayments.  Prepayments  occur when the
holder of an individual  debt  instrument  prepays the  remaining  principal and
interest before the final scheduled payment month.  Therefore,  each Fund may be
subject to a higher rate of  prepayments  during  periods of declining  interest
rates when mortgages and other debt instruments may be more frequently prepaid.

     Mortgage pass-through securities include (1) obligations of U.S. government
agencies and instrumentalities which are secured by the full faith and credit of
the U.S.  Treasury such as Government  National  Mortgage  Association  ("GNMA")
pass-through certificates; (2) obligations which are secured by the right of the
issuer to borrow from the  Treasury,  such as  securities  issued by the Federal
Financing  Bank,  the  Federal  Home Loan  Banks and the  United  States  Postal
Service;  and (3)  obligations  which have the principal  and interest  payments
guaranteed  by the  government  agency or  instrumentality  itself  (but are not
backed by the full faith and credit of the U.S. government),  such as securities
of the Federal  National  Mortgage  Association  ("FNMA")  and Federal Home Loan
Mortgage Corporation ("FHLMC"); and (4) obligations of private corporations.

ASSET-BACKED SECURITIES

     Each Fund may invest in types of  asset-backed  securities  which represent
forms of  consumer  credit  such as  automobile  and  credit  card  receivables,
manufactured  (mobile) home loans, home improvement loans and home equity loans.
Asset-backed  securities  are generally  privately  issued and pass through cash
flows to investors. Generally, asset-backed securities include many of the risks
associated with mortgage-related securities. In general, however, the collateral
supporting  asset-backed  securities is of shorter  maturity than mortgage loans
and  is  less  likely  to  experience  substantial   prepayments.   Asset-backed
securities   involve  certain  risks  that  are  not  posed  by  mortgage-backed
securities,  resulting mainly from the fact that asset-backed  securities do not
usually  contain  the  complete  benefit of a security  interest  in the related
collateral. For example, credit card receivables generally are unsecured and the
debtors are entitled to the protection of a number of state and federal consumer
credit laws, including the bankruptcy laws, some of which may reduce the ability
to obtain full payment.  In the case of automobile  receivables,  due to various

                                       10
<PAGE>

legal and economic factors,  proceeds for repossessed  collateral may not always
be sufficient to support payments on these securities.

ADJUSTING INVESTMENT EXPOSURE

     Each Fund may, but is not required to,  utilize  various  other  investment
strategies as described  below to hedge  various  market risks (such as interest
rates,  currency  exchange  rates,  and broad or  specific  fixed-income  market
movements),  to manage the effective  maturity or duration of a Fund's portfolio
or to enhance  potential gain.  These strategies may be executed through the use
of derivative  contracts.  Such  strategies are generally  accepted as a part of
modern portfolio  management and are regularly utilized by many mutual funds and
other institutional  investors.  Techniques and instruments may change over time
as new instruments and strategies are developed or regulatory changes occur.

     In the course of pursuing these investment strategies,  a Fund may purchase
and  sell   exchange-listed  and   over-the-counter  put  and  call  options  on
securities,  fixed-income indices and other financial instruments,  purchase and
sell  financial  futures  contracts  and  options  thereon,  enter into  various
interest  rate  transactions  such as swaps  and  enter  into  various  currency
transactions  such as currency forward  contracts,  currency futures  contracts,
currency swaps or options on currencies or currency futures.

     Such  techniques  and  instruments  may be used without limit to attempt to
protect against possible changes in the market value of securities held in or to
be  purchased  for a Fund's  portfolio  resulting  from  securities  markets  or
currency exchange rate fluctuations, to protect a Fund's unrealized gains in the
value of its portfolio securities, to facilitate the sale of such securities for
investment  purposes,  to manage the effective  maturity or duration of a Fund's
portfolio,  or to establish a position in the derivatives markets as a temporary
substitute for  purchasing or selling  particular  securities.  Some may also be
used to enhance  potential gain although no more than 5% of a Fund's assets will
be  committed  to  techniques  and  instruments  entered  into  for  non-hedging
purposes.  Any or all of these investment techniques may be used at any time and
in any combination, and there is no particular strategy that dictates the use of
one technique  rather than another,  as use of any technique or instruments is a
function of numerous  variables  including market  conditions.  The ability of a
Fund to utilize these  techniques and  instruments  successfully  will depend on
IAI's ability to predict  pertinent market  movements,  which cannot be assured.
Each Fund will comply with applicable regulatory  requirements when implementing
these  strategies,  techniques and instruments.  Such techniques and instruments
involving  financial  futures and options  thereon  will be  purchased,  sold or
entered into only for bona fide hedging, risk management or portfolio management
purposes and not for speculative purposes.

TEMPORARY INVESTMENTS

     Each Fund reserves the right,  as a temporary  defensive  measure,  such as
during periods of adverse market  conditions or when debt  securities are deemed
overvalued,  to hold up to 100% of its total assets in cash or cash  equivalents
and short-term securities, including money market securities.

BORROWING

   
     Each Fund may borrow from banks (or through reverse repurchase  agreements)
for temporary or emergency  purposes.  If a Fund borrows money,  its share price
may be subject to greater fluctuation until the borrowing is paid off. If a Fund
makes  additional  investments  while  borrowings are  outstanding,  this may be
considered a form of leverage.  Each Fund  currently has a line of credit with a
bank at the prime  interest rate. To the extent funds are drawn against the line
of credit, securities are held in a segregated account. No compensating balances
or commitment  fees are required  under the lines of credit.  Each Fund does not
intend its borrowings to exceed 5% of its net assets.
    
                                       11
<PAGE>


PORTFOLIO TURNOVER

     Each Fund will dispose of securities  without  regard to the time they have
been held when such action appears advisable to management either as a result of
securities  having reached a price  objective,  or by reason of developments not
foreseen  at the  time of the  investment  decision.  Since  investment  changes
usually will be made without reference to the length of time a security has been
held, a significant number of short-term transactions may result. Accordingly, a
Fund's  annual  portfolio  turnover  rate  cannot  be  anticipated  and  may  be
relatively  high, as the rates were for Bond and  Government  Funds for the last
fiscal year. High turnover rates (100% or more) increase  transaction costs, and
may increase taxable capital gains.  Each Fund's historical  portfolio  turnover
rates are set forth in the section "Financial Highlights.

     Further  information  regarding these and other  techniques is contained in
the Statement of Additional Information.

FUND RISK FACTORS

INTEREST RATE RISK

     As a mutual fund investing in fixed-income securities, each Fund is subject
to interest rate risk. Interest rate risk is the potential for a decline in bond
prices due to rising interest rates. In general, bond prices vary inversely with
interest  rates.   When  interest  rates  rise,  bond  prices   generally  fall.
Conversely,  when interest rates fall, bond prices generally rise. The change in
price  depends on  several  factors,  including  the bond's  maturity  date.  In
general,  bonds with longer maturities are more sensitive to changes in interest
rates than bonds with shorter  maturities.  In managing a Fund,  IAI will adjust
the  duration of the  investment  portfolio  in response to economic  and market
conditions.  Duration is generally  considered a better measure of interest rate
risk than is maturity.  Duration is a measure of the expected change in value of
a fixed income security (or portfolio) for a given change in interest rates. For
example,  if interest rates rise by one percent,  the market value of a security
(or portfolio) having a duration of two generally will fall by approximately two
percent. In some situations, the standard duration calculation does not properly
reflect the interest rate risk of a security.  In such situations,  IAI will use
more  sophisticated  analytical  techniques,  such  as  modeling  principal  and
interest payments based upon historical  experience or expected  volatility,  to
arrive at an effective duration that incorporates the additional  variables into
the  determination of interest rate risk. These techniques may involve estimates
of future economic  parameters which may vary from actual future  outcomes.  IAI
anticipates the following  duration ranges for the Funds: Bond Fund - 3.5 to 7.5
years;  and  Government  Fund  -  2.5  to  5  years.  These  ranges  are  merely
expectations  as of the date of this  Prospectus.  Such ranges may change due to
market conditions and other economic factors.  Therefore,  the expected duration
ranges do not limit IAI in how it manages each Fund.

     These principals of interest rate risk also apply to U.S. Treasury and U.S.
Government agency securities.  As with other bond investments,  U.S.  Government
securities  will rise and fall in value as  interest  rates  change.  A security
backed by the U.S. Treasury or the full faith and credit of the United States is
guaranteed  only as to the timely payment of interest and principal when held to
maturity.  The current market prices for such  securities are not guaranteed and
will fluctuate.

CREDIT RISK

     Each Fund is also  subject  to credit  risk.  Credit  risk,  also  known as
default  risk,  is the  possibility  that a bond issuer will fail to make timely
payments of interest or principal to the Fund. The credit risk of a Fund depends
on the quality of its investments.  Reflecting their higher risks, lower-quality
bonds generally offer higher yields (all other factors being equal).

                                       12
<PAGE>


CALL RISK

     Each Fund is also subject to call risk. Call risk is the  possibility  that
corporate  bonds  held  by a  Fund  will  be  repaid  prior  to  maturity.  Call
provisions, common in many corporate bonds held by a Fund, allow bond issuers to
redeem bonds prior to maturity (at a specified  price).  When interest rates are
falling,  bond issuers often  exercise these call  provisions,  paying off bonds
that carry  high  stated  interest  rates and often  issuing  new bonds at lower
rates.  For a Fund,  the result would be that bonds with high interest rates are
"called"  and  must  be  replaced  with  lower-yielding  instruments.  In  these
circumstances, the income of a Fund would decline.

FOREIGN INVESTMENT RISK FACTORS

     Investments in foreign  securities involve risks that are different in some
respects from  investments  in securities of U.S.  issuers,  such as the risk of
fluctuations in the value of the currencies in which they are  denominated,  the
risk of adverse political and economic developments and, with respect to certain
countries,  the possibility of  expropriation,  nationalization  or confiscatory
taxation  or  limitations  on the  removal  of funds or other  assets of a Fund.
Securities  of some foreign  companies  are less liquid and more  volatile  than
securities of  comparable  domestic  companies.  There also may be less publicly
available  information about foreign issuers than domestic issuers,  and foreign
issuers  generally  are not  subject to the  uniform  accounting,  auditing  and
financial reporting standards, practices and requirements applicable to domestic
issuers.  Because  a Fund can  invest  in  securities  denominated  or quoted in
currencies  other than the U.S.  dollar,  changes in foreign  currency  exchange
rates may affect the value of  securities  in the  portfolio.  Foreign  currency
exchange  rates are  determined  by forces of supply and  demand in the  foreign
exchange markets and other economic and financial conditions affecting the world
economy.  A decline in the value of any  particular  currency  against  the U.S.
dollar  will cause a decline in the U.S.  dollar  value of a Fund's  holdings of
securities  denominated in such currency and,  therefore,  will cause an overall
decline in a Fund's net asset value and net investment income and capital gains,
if any, to be distributed in U.S. dollars to shareholders by a Fund.  Delays may
be encountered in settling  securities  transactions in certain foreign markets,
and a Fund will incur costs in converting  foreign currencies into U.S. dollars.
Custody charges are generally higher for foreign securities.

RISKS ASSOCIATED WITH ADJUSTING INVESTMENT EXPOSURE

     The  techniques  and  instruments   described  in  the  section  "Adjusting
Investment Exposure", including derivative contracts, have risks associated with
them  including  possible  default  by  the  other  party  to  the  transaction,
illiquidity  and, to the extent  IAI's view as to certain  market  movements  is
incorrect, the risk that the use of such techniques and instruments could result
in losses  greater  than if they had not been used.  Use of put and call options
may  result  in  losses  to a Fund,  force  the sale or  purchase  of  portfolio
securities  at  inopportune  times or for prices higher than (in the case of put
options) or lower than (in the case of call  options),  current  market  values,
limit the amount of  appreciation a Fund can realize on its investments or cause
a Fund  to  hold a  security  it  might  otherwise  sell.  The  use of  currency
transactions  can result in a Fund  incurring  losses as a result of a number of
factors including the imposition of exchange controls, suspension of settlements
or the inability to deliver or receive a specified currency.  The use of options
and futures  transactions  entails  certain  other  risks.  In  particular,  the
variable degree of correlation  between price movements of futures contracts and
price  movements  in  the  related  portfolio  position  of a Fund  creates  the
possibility  that losses on the hedging  instrument may be greater than gains in
the value of a Fund's position. In addition, futures and options markets may not
be liquid in all circumstances and certain over-the-counter options may not have
markets.  As a result, in certain markets, a Fund might not be able to close out
a transaction without incurring  substantial losses, if at all. Although the use
of futures  contracts  and  options  transactions  for  hedging  should  tend to
minimize the risk of loss due to a decline in the value of the hedged  position,
at the same time they tend to limit any  potential  gain which might result from
an increase  in value of such  position.  Finally,  the daily  variation  margin
requirements  for futures  contracts  would create a greater  ongoing  potential
financial risk than would purchases of options, where the exposure is limited to
the  cost of the  initial  premium.  Losses  resulting  from  the  use of  these
techniques would reduce net asset value,  and possibly  income,  and such losses
can be greater than if the techniques and instruments had not been utilized.

                                       13
<PAGE>

MANAGER RISK

     IAI manages  each Fund  according  to the  traditional  methods of "active"
investment management,  which involve the buying and selling of securities based
upon economic,  financial and market analysis and investment  judgment.  Manager
risk  refers  to the  possibility  that  IAI may  fail to  execute  each  Fund's
investment strategy effectively.  As a result, each Fund may fail to achieve its
stated objective.

PREPAYMENT RISKS

     To the  extent  they  invest in  mortgage-backed  securities,  each Fund is
subject to prepayment risk. Prepayment risk is the possibility that, as interest
rates fall,  homeowners are more likely to refinance their home mortgages.  When
home mortgages are refinanced, the principal on GNMA certificates held by a Fund
is "prepaid" earlier than expected.  A Fund must then reinvest the unanticipated
principal in new GNMA  certificates,  or other  securities,  just at a time when
interest rates on new mortgage investments are falling.

     Prepayment risk has two important effects on a Fund:

     - When interest  rates fall and  additional  mortgage  prepayments  must be
reinvested at lower interest rates, the income of a Fund will be reduced.

     - When interest rates fall, prices on GNMA securities will not rise as much
as comparable Treasury bonds, as bond market investors anticipate an increase in
mortgage prepayments and a likely decline in income.

RISKS OF LOWER-RATED DEBT SECURITIES

     Bond Fund may invest in debt  securities  commonly  known as "junk"  bonds.
Such securities are subject to higher risks and greater market fluctuations than
are lower-yielding,  higher-rated  securities.  The price of junk bonds has been
found  to be less  sensitive  to  changes  in  prevailing  interest  rates  than
higher-rated investments, but is likely to be more sensitive to adverse economic
changes or individual  corporate  developments.  During an economic  downturn or
substantial  period of rising  interest  rates,  highly  leveraged  issuers  may
experience  financial  stress  which would  adversely  affect  their  ability to
service  their  principal  and  interest  payment  obligations,  to  meet  their
projected business goals or to obtain additional financing.  If the issuers of a
fixed-income  security  owned by a Fund were to  default,  such Fund might incur
additional expenses to seek recovery. The risk of loss due to default by issuers
of junk bonds is  significantly  greater than that associated with  higher-rated
securities  because such  securities  generally are unsecured and frequently are
subordinated to the prior payment of senior indebtedness.  In addition,  periods
of economic  uncertainty  and change can be  expected to result in an  increased
volatility of market  prices of junk bonds and a  concomitant  volatility in the
net asset value of a share of a Fund.

     The  secondary  market for junk bonds is less  liquid  than the markets for
higher quality securities and, as such, may have an adverse effect on the market
prices of  certain  securities.  The  limited  liquidity  of the market may also
adversely  affect the  ability  of a Fund to arrive at a fair value for  certain
junk  bonds at  certain  times and could  make it  difficult  for a Fund to sell
certain securities. For a description of Moody's and S&P ratings, see Appendix A
to the Statement of Additional Information.

INVESTMENT RESTRICTIONS

     Each Fund is subject to certain other investment  policies and restrictions
described  in the  Statement  of  Additional  Information,  some  of  which  are
fundamental and may not be changed without the approval of the shareholders of a
Fund. Each Fund is a diversified investment company and has a fundamental policy
that, with respect to 75% of its total assets, it may not invest more than 5% of
its total assets in any one issuer. Each Fund, also as fundamental policies, may
not invest 25% or more of its assets in any one industry and may borrow only for
temporary  or  emergency  purposes in an amount not  exceeding  one-third of its
total  assets.  Please refer to the Statement of  Additional  Information  for a
further discussion of each Fund's investment restrictions.

                                   MANAGEMENT
   
     Bond  Fund  was  created  on  August  18,  1977,  as a  separate  portfolio
represented by a separate class of common stock of IAI Investment Funds I, Inc.,
a Minnesota  corporation created on April 22, 1977.  Government Fund was created
on April 6, 1992 as a separate portfolio represented by separate class of common
stock of IAI Investment Funds VI, Inc., a Minnesota corporation created on April
30,  1991.  Under  Minnesota  law,  each Fund's  Board of Directors is generally
responsible for the overall operation and management of each Fund. IAI serves as
the investment  adviser of each Fund. IAI also  furnishes  investment  advice to
other concerns including other investment companies,  pension and profit sharing
plans, foundations,  religious, educational and charitable institutions, trusts,
municipalities  and  individuals,  having total assets in excess of $15 billion.
IAI's  ultimate  corporate  parent is  Lloyds  TSB Group  plc,  a  publicly-held
financial services  organization  headquartered in London,  England.  Lloyds TSB
Group plc is one of the largest personal and corporate financial services groups
in the United  Kingdom  and is engaged in a wide range of  activities  including
commercial and retail banking. The address of IAI is that of the Funds.

     Pursuant  to  a  written   agreement   with  each  Fund  (the   "Management
Agreement"),  IAI provides each Fund with  investment  advisory  services and is
responsible for the overall  management of each Fund's business  affairs subject
to the  authority  of the Board of  Directors.  The  Management  Agreement  also
provides  that,  except for  brokerage  commissions  and other  expenditures  in
connection with the purchase and sale of portfolio securities,  interest and, in
certain circumstances,  taxes and extraordinary expenses, IAI shall pay all of a
Fund's operating  expenses.  As compensation under the Management  Agreement for
the most recent  fiscal year,  each Fund paid IAI 1.10% of its average daily net
assets. The Management Agreement further provides that IAI will either reimburse
a Fund for the fees and  expenses it pays to directors  who are not  "interested
persons"  of a Fund or reduce its fee by an  equivalent  amount.  Because IAI is
paying Fund operating expenses, these fees represent each Fund's total expenses.
With respect to certain of the services  for which it is  responsible  under the
Management  Agreement,  IAI may  also  pay  directly  or  indirectly  qualifying
broker-dealers,  financial  institutions  and other  entities for providing such
services to Fund shareholders.  IAI shall not be liable for any loss suffered by
a Fund in the absence of willful  misfeasance,  bad faith or  negligence  in the
performance of its duties and obligations.

     Each Fund is managed by a team of IAI  investment  professionals.  The team
leads for each Fund are as follows.

     Larry Hill and Stephen Coleman are  responsible for Bond Fund's  day-to-day
investment  decisions.  Mr.  Hill is IAI's Chief  Fixed  Income  Officer and has
managed  Bond Fund since  joining  IAI in 1984.  Mr.  Coleman  is a Senior  Vice
President  of IAI and has  served  as a fixed  income  portfolio  manager  since
joining IAI in 1987.  Mr.  Coleman has been  involved in Bond Fund's  management
since mid-1996.

     Scott Bettin is responsible  for Government  Fund's  day-to-day  investment
decisions.  Mr.  Bettin is a Senior  Vice  President  of IAI and has served as a
fixed income portfolio manager since joining IAI in 1987. Mr. Bettin has managed
Government Fund since its inception.
    


                                       15

     The Funds and IAI have adopted a Code of Ethics,  which restricts  personal
investing  practices  by  employees  of IAI  and  its  affiliates.  Among  other
provisions,   the  Code  of  Ethics  requires  that  employees  with  access  to
information  about the purchase or sale of securities  in the Funds'  portfolios
obtain  preclearance before executing personal trades. With respect to portfolio
managers  and  other  investment   personnel,   the  Code  of  Ethics  prohibits
acquisition  of  securities  in an initial  public  offering,  as well as profit
derived from the purchase and sale of the same security within 60 calendar days.
These provisions are designed to ensure that the interests of Fund  shareholders
come before the interests of the people who manage the Funds.
    

   
     Consistent  with the  Rules  of  Conduct  of the  National  Association  of
Securities  Dealers,  Inc.,  IAI may consider  sales of shares of a Fund, or any
other IAI Mutual Fund, as a factor in the selection of broker-dealers to execute
a Fund's securities transactions.
    


                             INVESTMENT PERFORMANCE

     From  time to time,  each Fund may  advertise  performance  data  including
monthly,  quarterly,  yearly or cumulative  total return,  average  annual total
return and yield figures.  All such figures are based on historical earnings and
performance  and are not intended to be  indicative of future  performance.  The
investment  return  on and  principal  value  of an  investment  in a Fund  will
fluctuate,  so that an investor's  shares,  when redeemed,  may be worth more or
less than their original cost.

     Total return is the change in value of an investment in a Fund over a given
period,  assuming  reinvestment of any dividends and capital gains. A cumulative
total  return  reflects  actual  performance  over a stated  period of time.  An
average annual total return is a  hypothetical  rate of return that, if achieved
annually,  would have produced the same  cumulative  total return if performance
had been constant over the entire period.

     Yield  refers to the income  generated  by an  investment  in a Fund over a
given  period  of time,  expressed  as an annual  percentage  rate.  Yields  are
calculated  according to a standard that is required for all bond funds. Because
this differs from other accounting  methods,  the quoted yield may not equal the
income actually paid to  shareholders.  The tax equivalent  yield is computed by
dividing  the  portion  of the yield  that is  tax-exempt  by one minus a stated
income tax rate and adding the  product to that  portion,  if any,  of the yield
that is not tax-exempt.

     For additional  information  regarding the calculation of such total return
and yield figures,  see "Investment  Performance" in the Statement of Additional
Information. Further information about the performance of the Funds is contained
in the Funds' Annual Report to shareholders which may be obtained without charge
from the Funds.

     Comparative  performance  information  may be  used  from  time  to time in
advertising or marketing a Fund's shares,  including data on the  performance of
other  mutual  funds,  indexes or averages  of other  mutual  funds,  indexes of
related  financial  assets or data, and other  competing  investment and deposit
products available from or through other financial institutions. The composition
of these  indexes,  averages or  products  differs  from that of the Funds.  The
comparison  of  a  Fund  to  an  alternative  investment  should  be  made  with
consideration  of differences in features and expected  performance.  A Fund may
also note its  mention in  newspapers,  magazines,  or other  media from time to
time.  The Funds assume no  responsibility  for the  accuracy of such data.  For
additional  information on the types of indexes,  averages and periodicals  that
might be  utilized by the Funds in  advertising  and sales  literature,  see the
section "Investment Performance" in the Statement of Additional Information.

                   COMPUTATION OF NET ASSET VALUE AND PRICING

     Each  Fund is open  for  business  each  day the New  York  Stock  Exchange
("NYSE") is open. IAI normally calculates a Fund's net asset value ("NAV") as of
the close of business of the NYSE, normally 3 p.m. Central time.


                                       16
<PAGE>

     A Fund's NAV is the value of a single share.  The NAV is computed by adding
up the value of a Fund's  investments,  cash, and other assets,  subtracting its
liabilities, and then dividing the result by the number of shares outstanding.

     A Fund's  investments  with remaining  maturities of 60 days or less may be
valued on the basis of  amortized  cost.  This  method  minimizes  the effect of
changes in a security's market value. Other portfolio  securities and assets are
valued  primarily on the basis of market  quotations  or, if quotations  are not
readily available,  by a method that the Board of Directors believes  accurately
reflects fair value.  Foreign  securities  are valued on the basis of quotations
from the primary market in which they are traded,  and are  translated  from the
local currency into U.S. dollars using current exchange rates.

     The offering price (price to buy one share) and redemption  price (price to
sell one share) are referred to as a Fund's NAV.


                               PURCHASE OF SHARES

GENERAL

     Each Fund  offers  its  shares  continually  to the public at the net asset
value of such shares.  Shares may be purchased  directly  from a Fund or through
certain security dealers who have responsibility to promptly transmit orders and
may charge a  processing  fee,  provided  that the Fund  whose  shares are being
purchased  is duly  registered  in the state of the  purchaser's  residence,  if
required,   and  the  purchaser   otherwise   satisfies   the  Fund's   purchase
requirements.  No sales load or  commission  is charged  investors in connection
with the purchase of Fund shares.

     The minimum  initial  investment to establish a retail account with the IAI
Family of Funds is $5,000. Such initial investment may be allocated among a Fund
and other  funds in the IAI Family of Funds as  desired,  provided  that no less
than $1,000 is allocated to any one fund. The minimum initial investment for IRA
accounts is $2,000,  provided  that the minimum  amount that may be allocated to
any one fund is  $1,000.  Once the  account  minimum  has been  met,  subsequent
purchases  can be made in a Fund for $100 or more.  Such  minimums may be waived
for participants in the IAI Investment Club.

     Investors may satisfy the minimum  investment  requirement by participating
in the STAR  Program.  Participation  in the STAR  Program  requires  an initial
investment  of $1,000 per Fund and a commitment to invest an aggregate of $5,000
within 24 months. If a STAR Program  participant does not invest an aggregate of
$5,000 in the IAI Family of Funds  within 24  months,  IAI may,  at its  option,
redeem such shareholder's interest. Investors wishing to participate in the STAR
Program should contact a Fund to obtain a STAR Program application.

   
     To purchase shares,  forward the completed  application and a check payable
to "IAI Funds" to a Fund.  Third party  checks will not be accepted  for initial
account investments. Upon receipt, your account will be credited with the number
of full and fractional shares which can be purchased at the net asset value next
determined after receipt of the purchase order by a Fund.
    

     Purchases of shares are subject to acceptance or rejection by a Fund on the
same day the purchase  order is received and are not binding  until so accepted.
It is the  policy  of  the  Funds  and  the  Underwriter  to  keep  confidential
information  contained  in the  application  and  regarding  the  account  of an
investor or potential investor in the Funds.

     All correspondence relating to the purchase of shares should be directed to
the office of the Funds, P.O. Box 357, Minneapolis, Minnesota 55440 or, if using
overnight   delivery,   to  3700  First  Bank  Place,  601  Second  Ave.  South,
Minneapolis,  Minnesota  55402.  For  assistance in completing  the  application
please contact IAI Mutual Fund Shareholder Services at 1-800-945-3863.

BANK WIRE PURCHASES

     Shares may be purchased  by having your bank wire  federal  funds (funds of
the Federal Reserve System) to a Norwest Bank, Minnesota.

     Wire orders will be accepted only on days your bank, the transfer  agent, a
Fund and Norwest  Bank  Minnesota  are open for  business.  The payment  must be
received  by a Fund  before the close of  business to be credited to you account
that day.  Otherwise,  it will be  processed  the next  business  day.  The wire
purchase will not be considered  made until the wired amount is received and the
purchase  is  accepted  by such Fund.  If the wire order  does not  contain  the
information  stated below, such Fund may reject it. Any delays that may occur in
wiring federal funds,  including  delays in processing by the banks, are not the
responsibility of such Fund or the transfer agent.

     You must pay any charges  assessed by your bank for the wire service.  If a
wire order is rejected,  all money received by the Fund, less any costs incurred
by the Fund or the transfer agent in rejecting it, will be returned promptly.

     If the wire order is for a new  account,  you should  call IAI  Shareholder
Services at  1-800-945-3863  to advise them of the  investment  and to obtain an
account  number  and  instructions.  The wire  should be sent to:  Norwest  Bank
Minnesota,  Routing Number  091000019,  Minneapolis,  Minnesota,  Credit to: IAI
Mutual Funds Account Number 6355002264. It should state the following:

   
        "For further credit to personal account # ________________ (your
        account number) for ____________________________ (your name) and
                        __________________ (Fund name)."
    

     A completed application must be sent to and received by the Fund before the
wire is sent.

     If the wire order is an  addition  to an  existing  account,  the wire must
include the information required above for the new accounts. As soon as the wire
is sent,  you should call IAI  Shareholder  Services,  as described  above,  and
advise  them of  your  name,  your  account  number  and  the  name of the  bank
transmitting the federal funds.


                                RETIREMENT PLANS

     Shares of Bond and Government Funds may be an appropriate investment medium
for various Retirement Plans. Persons desiring information about establishing an
Individual  Retirement Account (IRA) (for employed persons and their spouses) or
other Retirement Plans should contact the Fund at 1-800-945-3863. All Retirement
Plans involve a long-term  commitment of assets and are subject to various legal
requirements and restrictions. The legal and tax implications may vary according
to the  circumstances of the individual  investor.  Therefore,  you are urged to
consult  with an attorney or tax advisor  prior to the  establishment  of such a
plan.

                            AUTOMATIC INVESTMENT PLAN
   
     Investors may arrange to make regular  investments of $100 or more per fund
on a monthly  basis,  effective  as of the 4th and/or 18th day of each month (or
the next business  day),  through  automatic  deductions  from their checking or
savings accounts.  Such investors may, of course,  terminate their participation
in the Automatic  Investment Plan at any time upon written notice to a Fund. Any
changes or instructions to terminate existing Automatic Investment Plans must be
received by the last business day of the preceding  month in which the change or
termination is to take place. Investors participating in an Automatic Investment
Plan will receive  quarterly  confirmations  of all  transactions and dividends.
Investors  interested in participating  in the Automatic  Investment Plan should
complete the Automatic Investment Plan application and return it to a Fund.

                              REDEMPTION OF SHARES

     Registered  holders of Fund shares may at any time require a Fund to redeem
their shares upon their  written  request.  All  correspondence  relating to the
redemption of shares should be directed to the office of IAI Mutual Funds,  P.O.
Box 357, Minneapolis,  Minnesota 55440. Shareholders may redeem shares by phone,
subject to a limit of $50,000,  provided such  shareholders have authorized such
Fund to accept  telephone  instructions.  For assistance in redeeming  shares by
phone,   please   contact  the  IAI  Mutual   Funds   Shareholder   Services  at
1-800-945-3863.

   
     Certificates presented for redemption must be endorsed on the back with the
signature  of the person  whose  name  appears  on the  certificate  and must be
signature guaranteed. If no certificate has been issued, redemption instructions
must be signed by the person(s) in whose name the shares are registered.  If the
redemption  proceeds  are to be paid or  mailed  to any  person  other  than the
shareholder of record or if redemption proceeds are in excess of $50,000, a Fund
will require that the signature on the written  instructions  be guaranteed by a
participant in a signature guarantee program, which may include certain national
banks or  trust  companies  or  certain  member  firms  of  national  securities
exchanges.  (Notarization by a Notary Public is NOT ACCEPTED.) If the shares are
held of record in the name of a corporation,  partnership, trust or fiduciary, a
Fund may require  additional  evidence of authority prior to accepting a request
for redemption.
    

     For shareholders who established  receiving  proceeds by Federal Funds Wire
at the time they opened their account,  telephone  instructions will be accepted
for  redemption  of amount up to $50,000  ($1,000  Minimum) and proceeds will be
wired on the next business day to a predesignated bank account.  Wire redemption
requests  will only be processed  on days your bank,  the  transfer  agent,  the
Portfolios and Norwest Bank Minnesota are open for business.

     In order to add this feature to an existing  account or to change  existing
bank account information,  please submit a letter of instructions including your
bank  information  to IAI  Shareholder  Services  at the  address  listed in the
section  "Additional  Information."  The letter must be signed by all registered
owners, and their signatures must be guaranteed.

     Your account will be charged a fee of $10 each time redemption proceeds are
wired to your bank.  Your bank may also charge you a fee for receiving a Federal
Funds Wire.

     Neither the transfer agent nor any of the Portfolios can be responsible for
the efficiency of the Federal Funds wire system or the shareholder's bank.

     The redemption proceeds received by the investor are based on the net asset
value next determined after  redemption  instructions in good order are received
by a Fund.  Since the value of shares redeemed is based upon the value of a Fund
investment  at the time of  redemption,  it may be more or less  than the  price
originally paid for the shares.

   
     If  redemptions  of Fund shares are arranged and  settlement  is made at an
investor's  election through a member of the National  Association of Securities
Dealers,  Inc.  or another  financial  intermediary,  such  entity  may,  at its
discretion, charge a fee for that service.
    

     Payment for shares redeemed will ordinarily be made within seven days after
a request for  redemption  has been made.  Normally a Fund will mail payment for
shares redeemed on the business day following receipt of the redemption request.
A Fund will not send  redemption  proceeds  until  checks  (including  certified
checks or cashiers  checks)  received in payment for shares have cleared,  which
may take up to ten days or more.


                                    19
<PAGE>



     Following a redemption or transfer request, if the value of a shareholder's
interest in a Fund falls below $500, such Fund reserves the right to redeem such
shareholder's entire interest and remit such amount. Such a redemption will only
be effected  following:  (a) a  redemption  or transfer by a  shareholder  which
causes the value of such shareholder's interest in such Fund to fall below $500;
(b) the mailing by such Fund to such  shareholder  of a notice of  intention  to
redeem;  and (c) the  passage  of at  least  six  months  from  the date of such
mailing,  during which time the investor  will have the  opportunity  to make an
additional  investment  in such Fund to  increase  the value of such  investor's
account to at least $500.

   
     Each Fund reserves the right, if conditions  exist which make cash payments
undesirable,  to honor any request for redemption or repurchase  order by making
payment in whole or in part in readily  marketable  securities  chosen by a Fund
and valued as they are for purposes of  computing  the Fund's net asset value (a
redemption-in-kind).  If payment is made in securities,  a shareholder may incur
transaction expenses in converting these securities to cash.
    

                               EXCHANGE PRIVILEGE

     The Exchange  Privilege enables  shareholders to purchase,  in exchange for
shares of a Fund, shares of certain other funds managed by IAI. These funds have
different investment objectives from the Funds. Shareholders may exchange shares
of a Fund for shares of another  fund  managed  by IAI,  provided  that the fund
whose  shares  will  be  acquired  is  duly  registered  in  the  state  of  the
shareholder's  residence,  if required,  and the shareholder otherwise satisfies
the fund's purchase  requirements.  Although the Funds do not currently charge a
fee for use of the  Exchange  Privilege,  they reserve the right to do so in the
future.

     Because excessive trading can hurt Fund performance and shareholders, there
is a limit of four  exchanges  out of each Fund per  calendar  year per account.
Accounts  under common  ownership or control,  including  accounts with the same
taxpayer  identification  number,  will be counted  together for purposes of the
four exchange limit.  Each Fund reserves the right to temporarily or permanently
terminate  the Exchange  Privilege  of any investor who exceeds this limit.  The
limit may be modified for certain  retirement plan accounts,  as required by the
applicable plan document and/or relevant  Department of Labor  regulations,  and
for Automatic Exchange Plan  participants.  Each Fund also reserves the right to
refuse or limit exchange  purchases by any investor if, in IAI's judgment,  such
Fund  would be unable to invest the money  effectively  in  accordance  with its
investment  objectives and policies, or would otherwise potentially be adversely
affected.

     Fund shareholders  wishing to exercise the Exchange Privilege should notify
a Fund in writing or,  provided  such  shareholders  have  authorized  a Fund to
accept telephone instructions, by telephone. At the time of the exchange, if the
net asset  value of the shares  redeemed  in  connection  with the  exchange  is
greater than the  investor's  cost, a taxable  capital gain will be realized.  A
capital loss will be realized if at the time of the exchange the net asset value
of the shares  redeemed in the exchange is less than the investor's  cost.  Each
Fund  reserves the right to  terminate  or modify the Exchange  Privilege in the
future.

                             AUTOMATIC EXCHANGE PLAN
   
     Investors may arrange to make regular exchanges of $100 or more between any
of the funds in the IAI Mutual Fund Family on a monthly  basis.  Exchanges  will
take  place at the  closing  price of the fifth  day of each  month (or the next
business day).  Shareholders  are responsible for making sure sufficient  shares
exist in the Fund account from which the exchange takes place.  If there are not
sufficient funds in a Fund account to meet the requested  exchange  amount,  the
Automatic  Exchange  Plan will be  suspended.  Shareholders  may not close  Fund
accounts  through the Automatic  Exchange Plan.  Investors  participating in the
Automatic Exchange Plan will receive quarterly confirmations of all transactions
and dividends.  Investors  interested in participating in the Automatic Exchange
Plan should complete the Automatic  Exchange Plan portion of their  application.
For assistance in completing the application contact IAI Mutual Fund Shareholder
Services at 1-800-945-3863.

<PAGE>

                          AUTHORIZED TELEPHONE TRADING

     Investors can transact account exchanges and redemptions via the
telephone by completing  the  Authorized  Telephone  Trading  section of the IAI
Mutual  Fund  application  and  returning  it to a  Fund.  Investors  requesting
telephone  trading  privileges  will be provided with a personal  identification
number ("PIN") that must  accompany any  instructions  by phone.  Shares will be
redeemed  or  exchanged  at the  next  determined  net  asset  value.  Telephone
redemption  proceeds are subject to a $50,000  limit and must be made payable to
the owner(s) of record and delivered to the address of record.

     In order  to  confirm  that  telephone  instructions  for  redemptions  and
exchanges  are  genuine,  the  Funds  have  established  reasonable  procedures,
including  the  requirement  that a  personal  identification  number  accompany
telephone  instructions.  If a Fund or the transfer  agent fails to follow these
procedures, such Fund may be liable for losses due to unauthorized or fraudulent
instructions.  To the extent the reasonable procedures are followed, none of the
Funds, their transfer agent, IAI, or any affiliated broker/dealer will be liable
for any loss, injury,  damage, or expense for acting upon telephone instructions
believed  to  be  genuine,  and  will  otherwise  not  be  responsible  for  the
authenticity of any telephone instructions, and, accordingly, the investor bears
the  risk  of  loss  resulting  from  telephone   instructions.   All  telephone
redemptions and exchange requests will be tape recorded.

                         SYSTEMATIC CASH WITHDRAWAL PLAN
   
     Each Fund has available a Systematic  Cash Withdrawal Plan for any investor
desiring to follow a program of  systematically  withdrawing  a fixed  amount of
money from an  investment in shares of a Fund.  Payments  under the plan will be
made monthly or  quarterly in amounts of $100 or more.  Shares will be sold with
the  closing  price of the 15th of the  applicable  month (or the next  business
day).  To  provide  funds  for  payment,  a Fund  will  redeem  as many full and
fractional  shares as  necessary  at the  redemption  price,  which is Net Asset
Value.  The  holder of a  Systematic  Cash  Withdrawal  Plan  must  have  income
dividends and any capital gains distributions  reinvested in full and fractional
shares  at  net  asset  value.  Investors  participating  in a  Systematic  Cash
Withdrawal Plan will receive  quarterly  confirmations  of all  transactions and
dividends.
    

     Payments under this plan,  unless pursuant to a retirement plan, should not
be considered income. Withdrawal payments may exceed dividends and distributions
and, to this extent,  there will be a reduction  in the  investor's  equity.  An
investor should also understand that this plan cannot insure profit, nor does it
protect against any loss in a declining market.  Careful consideration should be
given to the amount withdrawn each month.  Excessive withdrawals could lead to a
serious  depletion of equity,  especially  during  periods of  declining  market
values. Fund management will be available for consultation in this matter.

     Plan application forms are available through the Funds. If you would
like  assistance  in  completing  the   application   contact  IAI  Mutual  Fund
Shareholder Services at 1-800-945-3863.

                     DIVIDENDS, DISTRIBUTIONS AND TAX STATUS

     The  policy of each Fund is to pay  dividends  from net  investment  income
monthly and to make  distributions of realized capital gains, if any,  annually.
However,  provisions  in the  Internal  Revenue  Code of 1986,  as amended  (the
"Code"),  may result in  additional  net  investment  income and  capital  gains
distributions  by a Fund.  When you open an account,  you should specify on your
application how you want to receive your  distributions.  Each Fund offers three
options: Full Reinvestment--your dividend and capital gain distributions will be
automatically  reinvested  in  additional  shares of such  Fund;  Capital  Gains
Reinvestment--your  capital gain distributions will be automatically reinvested,
but your  income  dividend  distribution  will be paid in cash;  and  Cash--your
income  dividends  and  capital  gain   distributions  will  be  paid  in  cash.
Distributions  taken in cash can be sent via check or  transferred  directly  to
your  account at any bank,  savings and loan or credit union that is a member of
the Automated  Clearing House (ACH) network.  UNLESS INDICATED  OTHERWISE BY THE
SHAREHOLDER,  THE FUND WILL  AUTOMATICALLY  REINVEST ALL SUCH DISTRIBUTIONS INTO
FULL AND FRACTIONAL SHARES AT NET ASSET VALUE.

                                       16
<PAGE>

     The Funds'  Directed  Dividend  service allows you to invest your dividends
and/or capital gain distributions directly into another IAI Mutual Fund. Contact
IAI Mutual Fund Shareholder Services at 1-800-945-3863 for details.

     Each Fund  intends to  qualify  as a  regulated  investment  company  under
Subchapter M of the Code during the current taxable year. If so qualified,  each
Fund will not be subject to federal  income tax on income that it distributes to
its shareholders.

     Distributions are subject to federal income tax, and may also be subject to
state or local taxes. If you live outside the United States,  your distributions
could also be taxed by the country in which you reside.  Your  distributions are
taxable  when they are paid,  whether you take them in cash or reinvest  them in
additional shares.

   
     For federal income tax purposes,  each Fund's income and short-term capital
gain distributions are taxed as dividends;  long-term capital gain distributions
designated  as capital  gain  dividends  are taxed as long-term  capital  gains,
regardless  of the  length of time for which the shares  have been held.  In the
case of shareholders who are  individuals,  estates,  or trusts,  each Fund will
designate  the portion of each  capital  gain  dividend  that must be treated as
mid-term  capital  gain  ("28%  gain") and the  portion  that must be treated as
long-term  capital gain ("20%  gain").  Upon  redemption of shares of a Fund the
shareholder  will  generally  recognize  a  capital  gain or loss  equal  to the
difference  between the amount realized on the redemption and the  shareholder's
adjusted  basis in such shares.  For corporate  shareholders,  such gain or loss
will be long-term  gain or loss if the shares were held more than one year.  For
shareholders who are individuals,  estates,  or trusts, the gain or loss will be
considered  long-term (20% gain) if the shareholder has held the shares for more
than 18 months and mid-term  (28% gain) if the  shareholder  has held the shares
for more than one year but not more than 18 months.  
    

   
     On or  before  January  31 of each  year,  IAI will  send you and the IRS a
statement  showing the amount of each taxable  distribution  you received in the
previous  year.  Whenever  you  sell  shares  of a Fund,  IAI  will  send  you a
confirmation  statement  showing  how many  shares  you sold and at what  price.
However,  it is up to you or your tax  preparer to  determine  whether this sale
resulted in a capital gain and, if so, the amount of tax to be paid.  Be sure to
keep your  regular  account  statements;  the  information  they contain will be
essential in calculating the amount of your capital gains.
    

   
     Unless you are investing in a tax-deferred  retirement  account (such as an
IRA),  it is not to your  advantage  to buy shares of a Fund  shortly  before it
makes a distribution, because part of your investment will come back to you as a
taxable  distribution.  This is known as "buying a dividend."  For  example:  on
December 15, you invest $5,000, buying 250 shares for $20 each. If a Fund pays a
distribution  of $1 per share on December  16, its share price would drop to $19
(not counting market change). You would still have only $5,000 (250 shares x $19
= $4,750 in share value, plus 250 shares x $1 = $250 in distributions),  but you
would owe tax on the $250 distribution you received,  even if you had reinvested
the  dividends in more  shares.  To avoid  "buying a  dividend,"  check a Fund's
distribution schedule before you invest.
    

     The  foregoing  relates to federal  income  taxation as in effect as of the
date of this  Prospectus.  For a more detailed  discussion of the federal income
tax  consequences  of investing in shares of the Funds,  see "Tax Status" in the
Statement of Additional Information.

                           DESCRIPTION OF COMMON STOCK

     All shares of each Fund have equal rights as to  redemption,  dividends and
liquidation,  and will be fully paid and nonassessable when issued and will have
no preemptive or conversion rights.

     The shares of each Fund have noncumulative  voting rights, which means that
the holders of more than 50% of the shares  voting for the election of directors
can elect 100% of the directors if they choose to do so. On some issues, such as
the election of directors,  all shares of each  corporation vote together as one
series.  On an issue affecting only a particular  series,  such as voting on the
Advisory Agreement, only the approval of a particular series is required to make
the agreement effective with respect to such series.

     Annual or periodically  scheduled regular meetings of shareholders will not
be held except as required by law. Minnesota corporation law does not require an
annual  meeting;  instead,  it provides  for the Board of  Directors  to convene
shareholder  meetings  when it deems  appropriate.  In  addition,  if a  regular
meeting  of  shareholders  has not been held  during the  immediately  preceding
fifteen months,  shareholders holding three percent or more of the voting shares
of each  Fund may  demand a  regular  meeting  of  shareholders  of such Fund by
written  notice of  demand  given to the Chief  Executive  Officer  or the Chief
Financial  Officer of such Fund.  Within thirty days after receipt of the demand
by one of those  officers,  the Board of Directors shall cause a regular meeting
of shareholders to be called and held no later than ninety days after receipt of
the demand,  all at the expense of such Fund. An annual  meeting will be held on
the  removal of a director or  directors  of a Fund if  requested  in writing by
holders of not less than 10% of the outstanding shares of a Fund.

     The shares of each Fund are transferable by endorsement of the
certificate if held by the  shareholders,  or if the certificate is held by such
Fund, by delivery to such Fund of transfer  instructions.  Transfer instructions
or  certificates  should be  delivered to the office of such Fund. A Fund is not
bound to recognize any transfer until it is recorded on the stock transfer books
maintained by such Fund.

                             ADDITIONAL INFORMATION
   
     Each Fund sends to its shareholders a six-month unaudited and an annual
audited financial report, each of which includes a list of investment securities
held.  You will also receive an account  statement  quarterly and a consolidated
transaction  statement  and  updated  prospectus  annually.  Please  read  these
materials carefully as they will help you understand each Fund and your account.
To reduce the volume of mail you  receive,  only one copy of most Fund  reports,
such as a Fund's Annual Report,  may be mailed to your  household  (same surname
and address). Please call IAI Mutual Fund Shareholder Services at 1-800-945-3863
if you wish to receive additional shareholder reports.
    

   
     Carefully  review all the  information  relating  to  transactions  on your
statements  and  confirmations  to ensure that your  instructions  were acted on
properly.  Please notify us immediately in writing if there is an error.  If you
fail to provide  notification  of an error  with  reasonable  promptness,  i.e.,
within 30 days of  non-automatic  transactions  or within 30 days of the date of
your consolidated quarterly statement, in the case of automatic transactions, we
will deem you to have ratified the transaction.
    

     In the opinion of the staff of the Securities and Exchange Commission,  the
use of this  combined  Prospectus  may  possibly  subject all Funds to a certain
amount of liability  for any losses  arising out of any statement or omission in
this  Prospectus  regarding  a  particular  Fund.  In the  opinion of the Funds'
management,  however,  the risk of such liability is not materially increased by
the use of a combined Prospectus.

   
     The  investment  advisory,  transfer  agency  and  administrative  services
provided to each Fund byt IAI, depend on the smooth  functioning of its computer
systems. Many computer software systems in use today cannot distinguish the year
2000 from the year 1900  because of the way dates are  encoded  and  calculated.
That failure could have a negative impact on handling securities trades, pricing
and account services.  IAI has been actively working on necessary changes to its
computer systems to deal with the year 2000 and expects that its systems will be
adapted in time for that event, although there cannot be assurance of success.
    

     Shareholder  inquiries  should be  directed  to the Funds at the  telephone
number or mailing address listed on the back inside cover of this Prospectus.

   
     The following  table sets forth the  percentage  of securities  holdings by
rating category based upon a weighted  monthly average for the fiscal year ended
November 30, 1997 for IAI Bond Fund. The Government Fund did not hold 5% or more
of its assets in bonds rated below investment grade for the most recent year.

circumstances, taxes and extraordinary expenses). Additional information on such
agreement  is set forth in the  section  "Management"  and in the  Statement  of
Additional Information.

                        INVESTMENT OBJECTIVE AND POLICIES

     The Fund's investment objective is to provide shareholders with a high
level of total return  derived from a combination  of capital  appreciation  and
current income. Such objective may not be changed without shareholder  approval.
There can be no assurance that the Fund's investment objective will be attained.

     The Fund  pursues its  objective by  investing  primarily in a  diversified
portfolio  of  investment  grade  bonds and other  debt  securities  of  similar
quality.  Investment grade securities are those securities rated within the four
highest  grades  assigned by Moody's  Investors  Service,  Inc.  ("Moody's")  or
Standard & Poor's Corporation ("S&P").

   
     The  Fund may  also  invest  in below  investment  grade  securities.  Such
securities are commonly referred to as junk bonds. The Fund currently intends to
limit  such  investments  to 15% of its total  assets  and not to invest in junk
bonds  rated lower than B by Moody's or S&P.  Securities  rated in the medium to
lower  rating  of  categories  of  nationally   recognized   statistical  rating
organizations  and unrated  securities of comparable  quality are  predominately
speculative  with respect to the capacity to pay interest and repay principal in
accordance  with the  terms of the  security  and  generally  involve  a greater
volatility of price than securities in higher rating categories. See "Investment
Objective  and  Policies"  in  the  Statement  of  Additional   Information  for
additional information regarding ratings of debt securities.  In purchasing such
securities,  the Fund will rely on IAI's  judgment,  analysis and  experience in
evaluating the  creditworthiness of an issuer of such securities.  IAI will take
into consideration,  among other things, the issuer's financial  resources,  its
sensitivity  to economic  conditions  and trends,  its  operating  history,  the
quality  of the  issuer's  management  and  regulatory  matters.  Please see the
section  "Additional  Information" for further information on the credit quality
of securities owned by the Fund.
    

     Other debt  securities in which the Fund may invest include  securities of,
or   guaranteed   by,  the   United   States   Government,   its   agencies   or
instrumentalities,  debt securities of foreign issuers and commercial paper. The
Fund may also invest in U.S. Treasury inflation-protection securities. The value
of such  inflation-protection  securities is adjusted for inflation and periodic
interest   payments  are  in  amounts  equal  to  a  fixed   percentage  of  the
inflation-adjusted  value of the principal.  Under normal market conditions,  at
least 65% of the Fund's  total assets will be invested in debt  obligations  and
government  securities with maturities at the time of acquisition of one year or
more.

     Although the Fund generally will not make direct purchases of common stock,
the Fund may purchase  preferred  stock and  convertible  securities.  Preferred
stocks are securities that represent an ownership  interest in a corporation and
that give the owner a prior claim over common stock on the company's earnings or
assets.  Convertible securities are debt obligations of corporations convertible
into or exchangeable  for equity  securities or debt obligations that carry with
them the right to acquire equity  securities,  as evidenced by warrants attached
to such  securities,  or acquired as part of units of the securities.  The risks
associated  with  investing in preferred  stock and  convertible  securities are
different  from  those   traditionally   associated  with  investments  in  debt
securities.  Such  risks  are  similar  instead  to the  risks  associated  with
investments  in  equity  securities,  including  the risk  that the value of the
equity  security  will  fluctuate in response to the  activities  of the issuing
company or in response to general market and/or  economic  conditions.  The Fund
will limit its  investments  in such  securities  to a maximum of 10% of its net
assets.

     The Fund may employ certain other  investment  techniques,  as described in
the  section  "Other  Fund  Investment  Techniques."  Please see the  Prospectus
section "Fund Risk Factors" and the Statement of Additional  Information section
"Investment  Objective and  Policies"  for a discussion of the risks  associated
with investing in the Fund.

OTHER FUND INVESTMENT TECHNIQUES

REPURCHASE AGREEMENTS

     The Fund is  permitted  to invest in  repurchase  agreements.  A repurchase
agreement is a contract by which the Fund  acquires the security  ("collateral")
subject to the  obligation of the seller to  repurchase  the security at a fixed
price and date (within seven days). A repurchase agreement may be construed as a
loan under  relevant  law. The Fund may enter into  repurchase  agreements  with
respect to any securities  which it may acquire  consistent  with its investment
policies  and  restrictions.  The  Fund's  custodian  will  hold the  securities
underlying any  repurchase  agreement in a segregated  account.  In investing in
repurchase  agreements,  the Fund's risk is limited to the ability of the seller
to pay the agreed-upon price at the maturity of the repurchase agreement. In the
opinion  of IAI,  such  risk is not  material,  since in the  event of  default,
barring  extraordinary  circumstances,  the Fund would be  entitled  to sell the
underlying  securities or otherwise  receive  adequate  protection under federal
bankruptcy laws for its interest in such securities. However, to the extent that
proceeds from any sale upon a default are less than the  repurchase  price,  the
Fund could suffer a loss.  In  addition,  the Fund may incur  certain  delays in
obtaining direct ownership of the collateral.

WHEN-ISSUED/DELAYED DELIVERY TRANSACTIONS

     The Fund may purchase  securities on a  "when-issued"  or delayed  delivery
basis and purchase or sell securities on a "forward commitment" basis. When such
transactions  are  negotiated,  the price is fixed at the time the commitment is
made,  but delivery and payment for the  securities  take place at a later date.
Normally,  the settlement  date occurs within two months after the  transaction,
but delayed  settlements  beyond two months may be  negotiated.  At the time the
Fund enters into a transaction on a when-issued or forward  commitment  basis, a
segregated  account  consisting  of  cash,   government   securities  or  liquid
high-grade  debt  securities  equal to the value of the  when-issued  or forward
commitment  securities will be established and maintained with the custodian and
will be marked to the market daily.  During the period  between a commitment and
settlement, no payment is made for the securities and, thus, no interest accrues
to the  purchaser  from the  transaction.  If the Fund  disposes of the right to
acquire a when-issued security prior to its acquisition or disposes of its right
to deliver or receive against a forward commitment,  it can incur a gain or loss
due to market  fluctuation.  The use of  when-issued  transactions  and  forward
commitments  enables the Fund to hedge against  anticipated  changes in interest
rates and  prices.  The Fund may also enter into such  transactions  to generate
incremental income. In some instances,  the third-party seller of when-issued or
forward commitment securities may determine prior to the settlement date that it
will be unable or unwilling to meet its existing transaction commitments without
borrowing securities. If advantageous from a yield perspective, the Fund may, in
that event, agree to resell its purchase commitment to the third-party seller at
the current market price on the date of sale and concurrently enter into another
purchase  commitment  for such  securities at a later date. As an inducement for
the Fund to "roll  over"  its  purchase  commitment,  the  Fund  may  receive  a
negotiated  fee.  No more than 20% of the Fund's net assets may be  invested  in
when-issued,  delayed delivery or forward commitment  transactions,  and of such
20%,  no more than  one-half  (i.e.,  10% of its net  assets) may be invested in
when-issued,  delayed delivery or forward  commitment  transactions  without the
intention  of  actually  acquiring  securities  (i.e.,  dollar  rolls or  "roll"
transactions).  For additional information on roll transactions, see "Investment
Objectives  and  Policies  --  Dollar  Rolls"  in the  Statement  of  Additional
Information.

ILLIQUID SECURITIES

     The Fund may  invest  up to 15% of its net  assets in  securities  that are
considered  illiquid because of the absence of a readily available market or due
to legal or contractual  restrictions.  However,  certain restricted  securities
that are not registered for sale to the general public but that can be resold to
institutional  investors may be considered liquid pursuant to guidelines adopted
by the Board of Directors.  The institutional  trading market is relatively new,
and the  liquidity of the Fund's  investments  could be impaired if trading does
not develop or declines.

<PAGE>


ZERO COUPON OBLIGATIONS

     The Fund may also invest in zero coupon obligations of the U.S.  Government
or its agencies,  tax exempt issuers and corporate issuers,  including rights to
stripped coupon and principal payments ("STRIPS"). Zero coupon bonds do not make
regular interest payments;  rather, they are sold at a discount from face value.
Principal and accreted discount (representing interest accrued but not paid) are
paid at maturity. STRIPS are the components of debt securities that are stripped
of their interest after the securities are issued,  but otherwise are comparable
to zero  coupon  bonds.  The  market  values of  STRIPS  and zero  coupon  bonds
generally fluctuate in response to changes in interest rates to a greater degree
than do interest-paying securities of comparable term and quality.

MORTGAGE-BACKED SECURITIES

     The Fund may invest in  pass-through  securities  which are sold by various
private,   governmental  and  government-related   organizations.   Pass-through
securities  are formed  when  mortgages  and other debt  instruments  are pooled
together and undivided  interests in the pool are sold to investors  such as the
Fund. The cash flow from the underlying debt  instruments is "passed through" to
the  holders  of the  securities  in the form of  periodic  (generally  monthly)
payments of interest,  principal  and  prepayments.  Prepayments  occur when the
holder of an individual  debt  instrument  prepays the  remaining  principal and
interest before the final scheduled  payment month.  Therefore,  the Fund may be
subject to a higher rate of  prepayments  during  periods of declining  interest
rates when mortgages and other debt instruments may be more frequently prepaid.

     Mortgage pass-through securities include (1) obligations of U.S. government
agencies and instrumentalities which are secured by the full faith and credit of
the U.S.  Treasury such as Government  National  Mortgage  Association  ("GNMA")
pass-through certificates; (2) obligations which are secured by the right of the
issuer to borrow from the  Treasury,  such as  securities  issued by the Federal
Financing  Bank,  the  Federal  Home Loan  Banks and the  United  States  Postal
Service;  and (3)  obligations  which have the principal  and interest  payments
guaranteed  by the  government  agency or  instrumentality  itself  (but are not
backed by the full faith and credit of the U.S. government),  such as securities
of the Federal  National  Mortgage  Association  ("FNMA")  and Federal Home Loan
Mortgage Corporation ("FHLMC"); and (4) obligations of private corporations.

ASSET-BACKED SECURITIES

     The Fund may invest in types of  asset-backed  securities  which  represent
forms of  consumer  credit  such as  automobile  and  credit  card  receivables,
manufactured  (mobile) home loans, home improvement loans and home equity loans.
Asset-backed  securities  are generally  privately  issued and pass through cash
flows to investors. Generally, asset-backed securities include many of the risks
associated with mortgage-related securities. In general, however, the collateral
supporting  asset-backed  securities is of shorter  maturity than mortgage loans
and  is  less  likely  to  experience  substantial   prepayments.   Asset-backed
securities   involve  certain  risks  that  are  not  posed  by  mortgage-backed
securities,  resulting mainly from the fact that asset-backed  securities do not
usually  contain  the  complete  benefit of a security  interest  in the related
collateral. For example, credit card receivables generally are unsecured and the
debtors are entitled to the protection of a number of state and federal consumer
credit laws, including the bankruptcy laws, some of which may reduce the ability
to obtain full payment.  In the case of automobile  receivables,  due to various
legal and economic factors,  proceeds for repossessed  collateral may not always
be sufficient to support payments on these securities.

                                       7
<PAGE>


FOREIGN SECURITIES

     The Fund may  invest in  securities  issued  by  foreign  issuers,  whether
dollar-denominated  or not, including  securities issued or guaranteed by one or
more foreign  governments or any of their  political  subdivisions,  agencies or
instrumentalities,  including  obligations of supranational  entities,  that are
determined by IAI to be of comparable  quality to the other obligations in which
the Fund may invest.

ADJUSTING INVESTMENT EXPOSURE

     The Fund may, but is not  required to,  utilize  various  other  investment
strategies as described  below to hedge  various  market risks (such as interest
rates,  currency  exchange  rates,  and broad or  specific  fixed-income  market
movements), to manage the effective maturity or duration of the Fund's portfolio
or to enhance  potential gain.  These strategies may be executed through the use
of derivative  contracts.  Such  strategies are generally  accepted as a part of
modern portfolio  management and are regularly utilized by many mutual funds and
other institutional  investors.  Techniques and instruments may change over time
as new instruments and strategies are developed or regulatory changes occur.

     In the  course  of  pursuing  these  investment  strategies,  the  Fund may
purchase and sell  exchange-listed and  over-the-counter put and call options on
securities,  fixed-income indices and other financial instruments,  purchase and
sell  financial  futures  contracts  and  options  thereon,  enter into  various
interest  rate  transactions  such as swaps  and  enter  into  various  currency
transactions  such as currency forward  contracts,  currency futures  contracts,
currency swaps or options on currencies or currency futures.

     Such  techniques  and  instruments  may be used without limit to attempt to
protect against possible changes in the market value of securities held in or to
be purchased  for the Fund's  portfolio  resulting  from  securities  markets or
currency exchange rate  fluctuations,  to protect the Fund's unrealized gains in
the value of its portfolio securities, to facilitate the sale of such securities
for  investment  purposes,  to manage the effective  maturity or duration of the
Fund's  portfolio,  or to establish a position in the  derivatives  markets as a
temporary substitute for purchasing or selling particular  securities.  Some may
also be used to enhance  potential  gain  although no more than 5% of the Fund's
assets  will be  committed  to  techniques  and  instruments  entered  into  for
non-hedging  purposes.  Any or all of these investment  techniques maybe used at
any time  and in any  combination,  and  there is no  particular  strategy  that
dictates the use of one technique  rather than another,  as use of any technique
or instruments is a function of numerous variables  including market conditions.
The ability of the Fund to utilize these techniques and instruments successfully
will depend on IAI's ability to predict pertinent market movements, which cannot
be assured.  The Fund will comply with applicable  regulatory  requirements when
implementing these strategies,  techniques and instruments.  Such techniques and
instruments  involving  financial futures and options thereon will be purchased,
sold or entered into only for bona fide  hedging,  risk  management or portfolio
management purposes and not for speculative purposes.

TEMPORARY INVESTMENTS

     The Fund  reserves the right,  as a temporary  defensive  measure,  such as
during periods of adverse market  conditions or when debt  securities are deemed
overvalued,  to hold up to 100% of its total assets in cash or cash  equivalents
and short-term securities, including money market securities.

BORROWING
   
     The Fund may borrow from banks (or through reverse  repurchase  agreements)
for temporary or emergency purposes.  If the Fund borrows money, its share price
may be subject to greater  fluctuation  until the  borrowing is paid off. If the
Fund makes additional investments while borrowings are outstanding,  this may be
considered a form of leverage.  The Fund  currently  has a line of credit with a
bank at the prime  interest rate. To the extent funds are drawn against the line
of credit, securities are held in a segregated account. No compensating balances
or  commitment  fees are  required  under the line of credit.  The Fund does not
intend its borrowings to exceed 5% of its total assets.

<PAGE>


PORTFOLIO TURNOVER

     The Fund will dispose of  securities  without  regard to the time they have
been held when such action appears advisable to management either as a result of
securities  having reached a price  objective,  or by reason of developments not
foreseen  at the  time of the  investment  decision.  Since  investment  changes
usually will be made without reference to the length of time a security has been
held, a significant number of short-term  transactions may result.  Accordingly,
the Fund's  annual  portfolio  turnover  rate cannot be  anticipated  and may be
relatively  high, as it was for the last fiscal year.  High turnover rates (100%
or more) increase transaction costs, and may increase taxable capital gains. The
Fund's  historical  portfolio  turnover  rates  are  set  forth  in the  section
"Financial Highlights."

     Further  information  regarding these and other  techniques is contained in
the Statement of Additional Information.

                                FUND RISK FACTORS

INTEREST RATE RISK

     As a mutual fund investing in fixed-income securities,  the Fund is subject
to interest rate risk. Interest rate risk is the potential for a decline in bond
prices due to rising interest rates. In general, bond prices vary inversely with
interest  rates.   When  interest  rates  rise,  bond  prices   generally  fall.
Conversely,  when interest rates fall, bond prices generally rise. The change in
price  depends on  several  factors,  including  the bond's  maturity  date.  In
general,  bonds with longer maturities are more sensitive to changes in interest
rates than bonds with shorter maturities.  In managing the Fund, IAI will adjust
the  duration of the  investment  portfolio  in response to economic  and market
conditions.  Duration is generally  considered a better measure of interest rate
risk than is maturity.  Duration is a measure of the expected change in value of
a fixed income security (or portfolio) for a given change in interest rates. For
example,  if interest rates rise by one percent,  the market value of a security
(or portfolio) having a duration of two generally will fall by approximately two
percent. In some situations, the standard duration calculation does not properly
reflect the interest rate risk of a security.  In such situations,  IAI will use
more  sophisticated  analytical  techniques,  such  as  modeling  principal  and
interest payments based upon historical  experience or expected  volatility,  to
arrive at an effective duration that incorporates the additional  variables into
the  determination of interest rate risk. These techniques may involve estimates
of future economic  parameters which may vary from actual future  outcomes.  IAI
anticipates  that the  duration of the Fund will be from 3.5 to 7.5 years.  This
range is merely an expectation as of the date of this Prospectus. Such range may
change due to market  conditions  and other  economic  factors.  Therefore,  the
expected duration range does not limit IAI in how it manages the Fund.

CREDIT RISK

     The Fund is also subject to credit risk. Credit risk, also known as default
risk, is the possibility that a bond issuer will fail to make timely payments of
interest or  principal  to the Fund.  The credit  risk of a Fund  depends on the
quality of its investments.  Reflecting their higher risks,  lower-quality bonds
generally offer higher yields (all other factors being equal).

CALL RISK

     The Fund is also subject to call risk.  Call risk is the  possibility  that
corporate  bonds  held by the  Fund  will be  repaid  prior  to  maturity.  Call
provisions,  common in many corporate bonds held by the Fund, allow bond issuers
to redeem bonds prior to maturity (at a specified  price).  When interest  rates
are falling, bond issuers often exercise these call provisions, paying off bonds
that carry  high  stated  interest  rates and often  issuing  new bonds at lower
rates. For the Fund, the result would be that bonds with high interest rates are
"called"  and  must  be  replaced  with  lower-yielding  instruments.  In  these
circumstances, the income of the Fund would decline.

                                       9
<PAGE>

LOWER-RATED DEBT SECURITIES

     The Fund may invest in debt securities commonly known as "junk" bonds. Such
securities are subject to higher risks and greater market  fluctuations than are
lower-yielding,  higher-rated securities. The price of junk bonds has been found
to be less sensitive to changes in prevailing  interest rates than  higher-rated
investments,  but is likely to be more sensitive to adverse  economic changes or
individual  corporate  developments.  During an economic downturn or substantial
period of  rising  interest  rates,  highly  leveraged  issuers  may  experience
financial  stress which would  adversely  affect their  ability to service their
principal and interest  payment  obligations,  to meet their projected  business
goals or to  obtain  additional  financing.  If the  issuers  of a  fixed-income
security  owned by the Fund were to  default,  the Fund might  incur  additional
expenses  to seek  recovery.  The risk of loss due to default by issuers of junk
bonds is significantly greater than that associated with higher-rated securities
because such securities  generally are unsecured and frequently are subordinated
to the prior payment of senior  indebtedness.  In addition,  periods of economic
uncertainty  and change can be expected to result in an increased  volatility of
market prices of junk bonds and a concomitant  volatility in the net asset value
of a share of the Fund.

     The  secondary  market for junk bonds is less  liquid  than the markets for
higher quality securities and, as such, may have an adverse effect on the market
prices of  certain  securities.  The  limited  liquidity  of the market may also
adversely  affect the  ability of the Fund to arrive at a fair value for certain
junk bonds at certain  times and could  make it  difficult  for the Fund to sell
certain securities. For a description of Moody's and S&P ratings, see Appendix A
to the Statement of Additional Information.

PREPAYMENT RISKS

     To the extent it invests in mortgage-backed securities, the Fund is subject
to prepayment risk.  Prepayment risk is the possibility  that, as interest rates
fall,  homeowners are more likely to refinance their home  mortgages.  When home
mortgages are refinanced, the principal on GNMA certificates held by the Fund is
"prepaid"  earlier than expected.  The Fund must then reinvest the unanticipated
principal in new GNMA  certificates,  just at a time when interest  rates on new
mortgage investments are falling.

     Prepayment risk has two important effects on the Fund:

     - When interest  rates fall and  additional  mortgage  prepayments  must be
reinvested at lower interest rates, the income of the Fund will be reduced.

     - When interest rates fall, prices on GNMA securities will not rise as much
as comparable Treasury bonds, as bond market investors anticipate an increase in
mortgage prepayments and a likely decline in income.

FOREIGN INVESTMENT RISK FACTORS

     Investments in foreign  securities involve risks that are different in some
respects from  investments  in securities of U.S.  issuers,  such as the risk of
fluctuations in the value of the currencies in which they are  denominated,  the
risk of adverse political and economic developments and, with respect to certain
countries,  the possibility of  expropriation,  nationalization  or confiscatory
taxation or  limitations  on the  removal of funds or other  assets of the Fund.
Securities  of some foreign  companies  are less liquid and more  volatile  than
securities of  comparable  domestic  companies.  There also may be less publicly
available  information about foreign issuers than domestic issuers,  and foreign
issuers  generally  are not  subject to the  uniform  accounting,  auditing  and
financial reporting standards, practices and requirements applicable to domestic
issuers.  Because  the Fund can invest in  securities  denominated  or quoted in
currencies  other than the U.S.  dollar,  changes in foreign  currency  exchange
rates may affect the value of  securities  in the  portfolio.  Foreign  currency
exchange  rates are  determined  by forces of supply and  demand in the  foreign
exchange markets and other economic and financial conditions affecting the world
economy.  A decline in the value of any  particular  currency  against  the U.S.
dollar will cause a decline in the U.S.  dollar value of the Fund's  holdings of

                                       10
<PAGE>

securities  denominated in such currency and,  therefore,  will cause an overall
decline in the  Fund's net asset  value and net  investment  income and  capital
gains,  if any, to be distributed in U.S.  dollars to  shareholders by the Fund.
Delays may be encountered in settling securities transactions in certain foreign
markets,  and the Fund will incur costs in converting  foreign  currencies  into
U.S. dollars. Custody charges are generally higher for foreign securities.

RISKS ASSOCIATED WITH ADJUSTING INVESTMENT EXPOSURE

     The  techniques  and  instruments   described  in  the  section  "Adjusting
Investment Exposure", including derivative contracts, have risks associated with
them  including  possible  default  by  the  other  party  to  the  transaction,
illiquidity  and, to the extent  IAI's view as to certain  market  movements  is
incorrect, the risk that the use of such techniques and instruments could result
in losses  greater  than if they had not been used.  Use of put and call options
may  result  in losses to the Fund,  force  the sale or  purchase  of  portfolio
securities  at  inopportune  times or for prices higher than (in the case of put
options) or lower than (in the case of call  options),  current  market  values,
limit the amount of  appreciation  the Fund can  realize on its  investments  or
cause the Fund to hold a security it might  otherwise  sell. The use of currency
transactions  can result in the Fund incurring losses as a result of a number of
factors including the imposition of exchange controls, suspension of settlements
or the inability to deliver or receive a specified currency.  The use of options
and futures  transactions  entails  certain  other  risks.  In  particular,  the
variable degree of correlation  between price movements of futures contracts and
price  movements  in the  related  portfolio  position  of the Fund  creates the
possibility  that losses on the hedging  instrument may be greater than gains in
the value of the Fund's position.  In addition,  futures and options markets may
not be liquid in all circumstances and certain  over-the-counter options may not
have markets.  As a result,  in certain  markets,  the Fund might not be able to
close  out a  transaction  without  incurring  substantial  losses,  if at  all.
Although  the use of futures  contracts  and  options  transactions  for hedging
should  tend to  minimize  the risk of loss due to a decline in the value of the
hedged  position,  at the same time they tend to limit any potential  gain which
might  result  from an increase in value of such  position.  Finally,  the daily
variation  margin  requirements  for futures  contracts  would  create a greater
ongoing  potential  financial  risk than would  purchases of options,  where the
exposure is limited to the cost of the initial  premium.  Losses  resulting from
the use of these  techniques  would reduce net asset value, and possibly income,
and such losses can be greater than if the  techniques and  instruments  had not
been utilized.

MANAGER RISK

     IAI  manages  the Fund  according  to the  traditional  methods of "active"
investment management,  which involve the buying and selling of securities based
upon economic,  financial and market analysis and investment  judgment.  Manager
risk  refers  to the  possibility  that  IAI may  fail  to  execute  the  Fund's
investment strategy  effectively.  As a result, the Fund may fail to achieve its
stated objective.

INVESTMENT RESTRICTIONS

     The Fund is subject to certain other  investment  policies and restrictions
described  in the  Statement  of  Additional  Information,  some  of  which  are
fundamental and may not be changed  without the approval of the  shareholders of
the Fund.  The Fund is a  diversified  investment  company and has a fundamental
policy  that,  with respect to 75% of its total  assets,  it may not invest more
than 5% of its total  assets in any one issuer.  The Fund,  also as  fundamental
policies,  may not invest 25% or more of its assets in any one  industry and may
borrow only for  temporary  or  emergency  purposes  in an amount not  exceeding
one-third  of its total  assets.  Please refer to the  Statement  of  Additional
Information for a further discussion of the Fund's investment restrictions.

                                   MANAGEMENT
   
     The Fund was  created  on  September  27,  1993,  as a  separate  portfolio
represented by a separate class of common stock of IAI Investment Funds I, Inc.,
a Minnesota  corporation  created on April 22, 1977.  Under  Minnesota  law, the
Fund's Board of Directors is generally responsible for the overall operation and
management of the Fund. IAI serves as the investment  adviser and manager of the
Fund  pursuant  to a  written  agreement  (the  "Management  Agreement").  IAI's
ultimate  corporate  parent is Lloyds TSB Group plc, a  publicly-held  financial
services organization  headquartered in London, England. Lloyds TSB Group plc is
one of the largest  personal  and  corporate  financial  services  groups in the
United Kingdom and is engaged in a wide range of activities including commercial
and retail  banking.  IAI also  furnishes  investment  advice to other  concerns
including  other  investment  companies,   pension  and  profit  sharing  plans,
foundations,   religious,  educational  and  charitable  institutions,   trusts,
municipalities  and  individuals,  having total assets in excess of $15 billion.
The address of IAI is that of the Fund.
    

   
     IAI provides the Fund with investment  advisory services and is responsible
for the  overall  management  of the  Fund's  business  affairs  subject  to the
authority of the Board of  Directors.  The  Management  Agreement  also provides
that, except for brokerage commissions and other expenditures in connection with
the  purchase  and  sale  of  portfolio  securities,  interest  and  in  certain
circumstances,  taxes and  extraordinary  expenses,  IAI  shall  bear all of the
Fund's operating expenses. As compensation for these services, the Fund paid IAI
0.50% of its  average  daily net assets for the fiscal year ended  November  30,
1997. With respect to certain of the services for which it is responsible  under
the  Management  Agreement,  IAI may also directly or indirectly  pay qualifying
broker-dealers,  financial  institutions  and other  entities for providing such
services to Fund shareholders.  IAI shall not be liable for any loss suffered by
the Fund in the absence of willful misfeasance, bad faith or gross negligence in
performance of its duties and obligations.
    

     The Fund is managed by a team of IAI investment professionals.  Larry Hill,
Timothy  Palmer and Scott  Bettin  are  responsible  for the  Fund's  day-to-day
investment  decisions.  Mr. Hill and Mr.  Palmer have been  responsible  for the

     The Fund and IAI have adopted a Code of Ethics,  which  restricts  personal
investing  practices  by  employees  of IAI  and  its  affiliates.  Among  other
provisions,   the  Code  of  Ethics  requires  that  employees  with  access  to
information  about the purchase or sale of securities  in the Fund's  portfolios
obtain  preclearance before executing personal trades. With respect to portfolio
managers  and  other  investment   personnel,   the  Code  of  Ethics  prohibits
acquisition  of securities  in an initial  public  offering,  as well as profits
derived from the purchase and sale of the same security within 60 calendar days.
These  provisions  are  designed  to  ensure  that  the  interests  of the  Fund
shareholders come before the interests of the people who manage the Fund.
    

                             INVESTMENT PERFORMANCE

     From  time to time  the  Fund  may  advertise  performance  data  including
monthly,  quarterly,  yearly or cumulative  total return,  average  annual total
return and yield figures.  All such figures are based on historical earnings and
performance  and are not intended to be  indicative of future  performance.  The
investment  return  on and  principal  value of an  investment  in the Fund will
fluctuate,  so that an investor's  shares,  when redeemed,  may be worth more or
less than their original cost.

     Total  return is the  change in value of an  investment  in the Fund over a
given  period,  assuming  reinvestment  of any dividends  and capital  gains.  A
cumulative  total return  reflects  actual  performance  over a stated period of
time. An average annual total return is a  hypothetical  rate of return that, if
achieved  annually,  would have  produced  the same  cumulative  total return if
performance had been constant over the entire period.

                                       12
<PAGE>

     Yield refers to the income  generated by an  investment  in the Fund over a
given  period  of time,  expressed  as an annual  percentage  rate.  Yields  are
calculated  according  to a  standard  that is  required  for all stock and bond
funds.  Because this differs from other accounting methods, the quoted yield may
not equal the income actually paid to shareholders.

     For additional  information  regarding the calculation of such total return
and yield figures,  see "Investment  Performance" in the Statement of Additional
Information.  Further information about the performance of the Fund is contained
in the Fund's Annual Report to shareholders which may be obtained without charge
from the Fund.

     Comparative  performance  information  may be  used  from  time  to time in
advertising or marketing the Fund's shares, including data on the performance of
other  mutual  funds,  indexes or averages  of other  mutual  funds,  indexes of
related  financial  assets or data, and other  competing  investment and deposit
products available from or through other financial institutions. The composition
of these  indexes,  averages  or  products  differs  from that of the Fund.  The
comparison  of the  Fund  to an  alternative  investment  should  be  made  with
consideration of differences in features and expected performance.  The Fund may
also note its  mention in  newspapers,  magazines,  or other  media from time to
time.  The Fund assumes no  responsibility  for the  accuracy of such data.  For
additional  information on the types of indexes,  averages and periodicals  that
might be  utilized  by the Fund in  advertising  and sales  literature,  see the
section "Investment Performance" in the Statement of Additional Information.

                   COMPUTATION OF NET ASSET VALUE AND PRICING

     The Fund is open for business each day the New York Stock Exchange ("NYSE")
is open.  IAI normally  calculates  the Fund's net asset value ("NAV") as of the
close of business of the NYSE, normally 3 p.m. Central time.

     The  Fund's  NAV is the value of a single  share.  The NAV is  computed  by
adding  up  the  value  of the  Fund's  investments,  cash,  and  other  assets,
subtracting  its  liabilities,  and then  dividing  the  result by the number of
shares outstanding.

     The Fund's investments with remaining  maturities of 60 days or less at the
date of initial  investment may be valued on the basis of amortized  cost.  This
method  minimizes  the effect of changes in a  security's  market  value.  Other
portfolio  securities  and assets are  valued  primarily  on the basis of market
quotations  or, if quotations  are not readily  available,  by a method that the
Board of Directors believes accurately  reflects fair value.  Foreign securities
are valued on the basis of quotations  from the primary market in which they are
traded,  and are  translated  from the local  currency  into U.S.  dollars using
current exchange rates.

     The offering price (price to buy one share) and redemption  price (price to
sell one share) are the Fund's NAV next computed  after receipt by the Fund of a
purchase or redemption order.


                               PURCHASE OF SHARES

GENERAL

     The Fund offers its shares continually to the public at the net asset value
of such  shares.  Shares  may be  purchased  directly  from the Fund or  through
certain security dealers who have responsibility to promptly transmit orders and
may  charge a  processing  fee.  No  sales  load or  commission  is  charged  in
connection with the purchase of Fund shares.

                                       13
<PAGE>


     The  minimum  initial  investment  in the Fund is $2  million.  The minimum
investment  requirement may be waived or lowered for  investments  effected on a
group  basis by certain  entities  and their  employees,  such as  pursuant to a
payroll deduction plan.

     Shares may be purchased  for cash or in exchange for  securities  which are
permissible  investments  of the  Fund,  subject  to  IAI's  discretion  and its
determination  that  the  securities  are  acceptable.  Securities  accepted  in
exchange  will be  valued  on the  basis of  market  quotations  or,  if  market
quotations are not available,  by a method that IAI believes accurately reflects
fair value.  In  addition,  securities  accepted in exchange  are required to be
liquid securities that are not restricted as to transfer.

     Purchases of shares are subject to  acceptance  or rejection by the Fund on
the same  day the  purchase  order  is  received  and are not  binding  until so
accepted.  It is the  policy  of  the  Fund  to  keep  confidential  information
contained  in the  application  and  regarding  the  account of an  investor  or
potential  investor  in the  Fund.  All  funds  will be  invested  in  full  and
fractional shares of the Fund. Share certificates will not be issued.

     All correspondence relating to the purchase of shares should be directed to
the office of the Fund, P.O. Box 357, Minneapolis,  Minnesota 55440 or, if using
overnight delivery, to 3700 First Bank Place, 601 2nd Avenue South, Minneapolis,
Minnesota 55402. For assistance in completing the application please contact IAI
Mutual Fund Shareholder Services at 1-800-945-3863.

BANK WIRE PURCHASES

     Shares may be purchased  by having your bank wire  federal  funds (funds of
the Federal Reserve System) to Norwest Bank, Minnesota.

     Wire orders will be accepted  only on days your bank,  the transfer  agent,
the Fund and Norwest Bank  Minnesota are open for business.  The payment must be
received  by the Fund before the close of business to be credited to you account
that day.  Otherwise,  it will be  processed  the next  business  day.  The wire
purchase will not be considered  made until the wired amount is received and the
purchase  is  accepted  by the Fund.  If the wire  order  does not  contain  the
information  stated below,  the Fund may reject it. Any delays that may occur in
wiring federal funds,  including  delays in processing by the banks, are not the
responsibility of the Fund or the transfer agent.

     You must pay any charges  assessed by your bank for the wire service.  If a
wire order is rejected,  all money received by the Fund, less any costs incurred
by the Fund or the transfer agent in rejecting it, will be returned promptly.

     If the wire order is for a new  account,  you should  call IAI  Shareholder
Services at  1-800-945-3863  to advise them of the  investment  and to obtain an
account  number  and  instructions.  The wire  should be sent to:  Norwest  Bank
Minnesota,  Routing Number  091000019,  Minneapolis,  Minnesota,  Credit to: IAI
Mutual Funds Account Number 6355002264. It should state the following:

   
       "For further credit to personal account # ___________________ (your
          account number) for ________________________ (your name) and
                        __________________ (Fund name)."
    

     A completed application must be sent to and received by the Fund before the
wire is sent.

     If the wire order is an  addition  to an  existing  account,  the wire must
include the information required above for the new accounts. As soon as the wire
is sent,  you should call IAI  Shareholder  Services,  as described  above,  and
advise  them of  your  name,  your  account  number  and  the  name of the  bank
transmitting the federal funds.

                                RETIREMENT PLANS

     Shares of the Fund may be an  appropriate  investment  medium  for  various
retirement plans.  Persons desiring information about establishing an Individual
Retirement  Account  (IRA) (for  employed  persons  and their  spouses) or other
retirement plans should contact the Fund at 1-800-945-3863. All retirement plans
involve a  long-term  commitment  of assets and are  subject  to  various  legal
requirements and restrictions. The legal and tax implications may vary according
to the  circumstances of the individual  investor.  Therefore,  you are urged to
consult  with an attorney or tax advisor  prior to the  establishment  of such a
plan.

                              REDEMPTION OF SHARES

     Registered  holders  of Fund  shares  may at any time  require  the Fund to
redeem their shares upon their written request.  All correspondence  relating to
the  redemption  of shares should be directed to the office of IAI Mutual Funds,
P.O. Box 357,  Minneapolis,  Minnesota 55440.  Shareholders may redeem shares by
phone, subject to a limit of $50,000, provided such shareholders have authorized
the Fund to accept telephone instructions. For assistance in redeeming shares by
phone,   please   contact  the  IAI  Mutual   Funds   Shareholder   Services  at
1-800-945-3863.

     Redemption  instructions  must be made by the  person(s)  in whose name the
shares are  registered.  If the redemption  proceeds are to be paid or mailed to
any person other than the shareholder of record or if redemption proceeds are in
excess of  $50,000,  the Fund will  require  that the  signature  on the written
instructions  be guaranteed by a participant in a signature  guarantee  program,
which may include  certain  national banks or trust  companies or certain member
firms of national securities exchanges.  (Notarization by a Notary Public is NOT
ACCEPTED.)  If the  shares  are held of  record  in the  name of a  corporation,
partnership,  trust or fiduciary,  the Fund may require  additional  evidence of
authority prior to accepting a request for redemption.

     For shareholders who established  receiving  proceeds by Federal Funds Wire
at the time they opened their account,  telephone  instructions will be accepted
for  redemption  of amount up to $50,000  ($1,000  Minimum) and proceeds will be
wired on the next business day to a predesignated bank account.  Wire redemption
requests will only be processed on days your bank, the transfer agent,  the Fund
and Norwest Bank Minnesota are open for business.

     In order to add this feature to an existing account or to change
existing  bank  account  information,  please  submit a letter  of  instructions
including your bank information to IAI Shareholder Services.  The letter must be
signed by all registered owners, and their signatures must be guaranteed.

     Your account will be charged a fee of $10 each time redemption proceeds are
wired to your bank.  Your bank may also charge you a fee for receiving a Federal
Funds wire.

     Neither  the  transfer  agent  nor  the  Fund  can be  responsible  for the
efficiency of the Federal Funds wire system or the shareholder's bank.

     The redemption proceeds received by the investor are based on the net asset
value next determined after  redemption  instructions in good order are received
by the Fund.  Since the value of shares  redeemed is based upon the value of the
Fund investment at the time of redemption, it may be more or less than the price
originally paid for the shares.

   
     If purchases and  redemption of Fund shares are arranged and  settlement is
made at an investor's  election through a member of the National  Association of
Securities Dealers, Inc. or another financial intermediary,  such entity may, at
its discretion, charge a fee for that service.
    

                                       15
<PAGE>


     Payment for shares redeemed will ordinarily be made within seven days after
a request for redemption has been made.  Normally the Fund will mail payment for
shares redeemed on the business day following receipt of the redemption request.
The Fund will not send  redemption  proceeds until checks  (including  certified
checks or cashiers  checks)  received in payment for shares have cleared,  which
may take up to ten days or more.

     Following a redemption or transfer request, if the value of a shareholder's
interest  in the Fund falls  below $2 million,  the Fund  reserves  the right to
redeem  such  shareholder's  entire  interest  and  remit  such  amount.  Such a
redemption  will only be effected  following:  (a) a redemption or transfer by a
shareholder which causes the value of such shareholder's interest in the Fund to
fall below $2  million;  (b) the  mailing by the Fund to such  shareholder  of a
notice of intention  to redeem;  and (c) the passage of at least sixty days from
the  date of such  mailing,  during  which  time  the  investor  will  have  the
opportunity  to make an additional  investment in the Fund to increase the value
of such investor's account to at least $2 million.

   
     The Fund reserves the right,  if conditions  exist which make cash payments
undesirable,  to honor any request for redemption or repurchase  order by making
payment in whole or in part in readily marketable  securities chosen by the Fund
and valued as they are for purposes of  computing  the Fund's net asset value (a
redemption-in-kind).  If payment is made in securities,  a shareholder may incur
transaction expenses in converting these securities to cash.
    

                          AUTHORIZED TELEPHONE TRADING

     Investors can transact account  exchanges and redemptions via the telephone
by completing the Authorized  Telephone  Trading  section of the IAI Mutual Fund
application and returning it to the Fund. Investors requesting telephone trading
privileges will be provided with a personal  identification  number ("PIN") that
must accompany any  instructions by phone.  Shares will be redeemed or exchanged
at the next determined net asset value. All proceeds must be made payable to the
owner(s) of record and delivered to the address of record.

     In order  to  confirm  that  telephone  instructions  for  redemptions  and
exchanges are genuine, the Fund has established  reasonable procedures including
the  requirement  that a  personal  identification  number  accompany  telephone
instructions. If the Fund or the transfer agent fail to follow these procedures,
the  Fund  may  be  liable  for  losses  due  to   unauthorized   or  fraudulent
instructions.  To the extent the reasonable procedures are followed, none of the
Fund, its transfer agent, IAI or any affiliated broker/dealer will be liable for
any loss,  injury,  damage or expense  for acting  upon  telephone  instructions
believed  to  be  genuine  and  will  otherwise  not  be  responsible   for  the
authenticity of any telephone instructions and, accordingly,  the investor bears
the  risk  of  loss  resulting  from  telephone   instructions.   All  telephone
redemptions and exchange requests will be tape recorded.


                     DIVIDENDS, DISTRIBUTIONS AND TAX STATUS

     The  policy  of the Fund is to pay  dividends  from net  investment  income
monthly and to make  distributions of realized capital gains, if any,  annually.
However,  provisions  in the  Internal  Revenue  Code of 1986,  as amended  (the
"Code"),  may result in  additional  net  investment  income and  capital  gains
distributions by the Fund. When you open an account,  you should specify on your
application how you want to receive your distributions.  Normally,  all dividend
and capital gain distributions are automatically reinvested in additional shares
of the Fund.

     The Fund  intends to qualify for tax  purposes  as a  regulated  investment
company under the Code during the current  taxable  year.  If so qualified,  the
Fund will not be subject to federal  income tax on income that it distributes to
its shareholders.

     Distributions   are  subject  to  federal   income  tax  in  the  hands  of
shareholders subject to tax, and may also be subject to state or local taxes. If
you live outside the United States,  your  distributions  could also be taxed by
the country in which you reside.  Your  distributions  are taxable when they are
paid, whether you take them in cash or reinvest them in additional shares.

                                       16
<PAGE>

   
     For federal income tax purposes,  the Fund's income and short-term  capital
gain distributions are taxed as dividends;  long-term capital gain distributions
designated  as capital  gain  dividends  are taxed as  long-term  capital  gain,
regardless  of the  length of time for which the shares  have been held.  In the
case of shareholders  who are  individuals,  estates,  or trusts,  the Fund will
designate  the portion of each  capital  gain  dividend  that must be treated as
mid-term  capital  gain  ("28%  gain") and the  portion  that must be treated as
long-term  capital gain ("20% gain").  Upon  redemption of shares of the Fund, a
shareholder  will  generally  recognize  a  capital  gain or loss  equal  to the
difference  between the amount realized on the redemption and the  shareholder's
adjusted  basis in such shares.  For corporate  shareholders,  such gain or loss
will be long-term  gain or loss if the shares were held more than one year.  For
shareholders who are individuals,  estates,  or trusts, the gain or loss will be
considered  long-term (20% gain) if the shareholder has held the shares for more
than 18 months and mid-term  (28% gain) if the  shareholder  has held the shares
for more than one year but not more than 18 months.
    

     Generally,  dividends and capital gain distributions with respect to shares
held by a  tax-deferred  or  qualified  pension  plan,  such as an IRA,  Section
403(b)(7)  retirement plan or corporate pension or profit sharing plan, will not
be  taxable  to the plan.  Distributions  from such  plans  will be  taxable  to
individual  participants  under  applicable  tax  rules  without  regard  to the
character of the income earned by the qualified plan. If you participate in such
a plan, consult your plan  administrator,  your plan's Summary Plan Description,
or  a  professional   tax  advisor   regarding  the  tax  consequences  of  your
participation in the plan, and of any plan contributions or withdrawals.

   
     Unless you are investing in a tax-deferred  retirement  account (such as an
IRA),  it is not to your  advantage to buy shares of the Fund shortly  before it
makes a distribution, because part of your investment will come back to you as a
taxable  distribution.  This is known as "buying a dividend."  For  example:  on
December 15, you invest $5,000, buying 250 shares for $20 each. If the Fund pays
a distribution of $1 per share on December 16, its share price would drop to $19
(not counting market change). You would still have only $5,000 (250 shares x $19
= $4,750 in share value, plus 250 shares x $1 = $250 in distributions),  but you
would owe tax on the $250 distribution you received,  even if you had reinvested
the  dividends in more shares.  To avoid  "buying a dividend,"  check the Fund's
distribution schedule before you invest.
    
   
     The  foregoing  relates to federal  income  taxation as in effect as of the
date of this  Prospectus.  For a more detailed  discussion of the federal income
tax  consequences  of investing  in shares of the Fund,  see "Tax Status" in the
Statement of Additional Information.
    

                           DESCRIPTION OF COMMON STOCK

     All shares of the Fund have equal rights as to  redemption,  dividends  and
liquidation,  and will be fully paid and nonassessable when issued and will have
no preemptive or conversion rights.

     The shares of the Fund have noncumulative  voting rights,  which means that
the holders of more than 50% of the shares  voting for the election of directors
can elect 100% of the directors if they choose to do so. On some issues, such as
the election of  directors,  all shares of IAI  Investment  Funds I, Inc.,  vote
together as one series. On an issue affecting only a particular series,  such as
voting on an investment  advisory  agreement,  only the approval of a particular
series is required to make the agreement effective with respect to such series.

                                       17
<PAGE>


     Annual or periodically  scheduled regular meetings of shareholders will not
be held except as required by law. Minnesota corporation law does not require an
annual  meeting;  instead,  it provides  for the Board of  Directors  to convene
shareholder  meetings  when it deems  appropriate.  In  addition,  if a  regular
meeting  of  shareholders  has not been held  during the  immediately  preceding
fifteen months,  shareholders holding three percent or more of the voting shares
of the Fund may demand a regular  meeting of shareholders of the Fund by written
notice of demand  given to the chief  executive  officer or the chief  financial
officer of the Fund.  Within  thirty days after  receipt of the demand by one of
those  officers,  the  Board of  Directors  shall  cause a  regular  meeting  of
shareholders  to be called and held no later than ninety  days after  receipt of
the demand,  all at the expense of the Fund.  An annual  meeting will be held on
the removal of a director or  directors  of the Fund if  requested in writing by
holders of not less than 10% of the outstanding shares of the Fund.


                              COUNSEL AND AUDITORS

     The firm of Dorsey & Whitney  LLP,  220 South  Sixth  Street,  Minneapolis,
Minnesota 55402, provides legal counsel to the Fund. KPMG Peat Marwick LLP, 4200
Norwest Center, Minneapolis, Minnesota 55402, serves as the independent auditors
for the Fund.


             CUSTODIAN, TRANSFER AGENT AND DIVIDEND DISBURSING AGENT
   
     The Custodian for the Fund is Norwest Bank Minnesota, N.A., Norwest Center,
Sixth  and  Marquette,  Minneapolis,  Minnesota  55479.  IAI acts as the  Fund's
transfer agent,  dividend  disbursing agent and IRA Custodian,  at P.O. Box 357,
Minneapolis, Minnesota 55440.
    

                             ADDITIONAL INFORMATION
   
     The Fund sends to its  shareholders  a  six-month  unaudited  and an annual
audited financial report, each of which includes a list of investment securities
held.  You will also receive an account  statement  quarterly and a consolidated
transaction  statement  and  updated  prospectus  annually.  Please  read  these
materials  carefully as they will help you understand the Fund and your account.
To reduce the volume of mail you  receive,  only one copy of most Fund  reports,
such as the Fund's Annual Report,  may be mailed to your household (same surname
and address). Please call IAI Mutual Fund Shareholder Services at 1-800-945-3863
if you wish to receive additional shareholder reports.
    

   
     Carefully  review all the  information  relating  to  transactions  on your
statements  and  confirmations  to ensure that your  instructions  were acted on
properly.  Please notify us immediately in writing if there is an error.  If you
fail to provide  notification  of an error  with  reasonable  promptness,  i.e.,
within 30 days of  non-automatic  transactions  or within 30 days of the date of
your consolidated quarterly statement, in the case of automatic transactions, we
will deem you to have ratified the transaction.
    

   
     The  investment  advisory,  transfer  agency  and  administrative  services
provided to the Fund by IAI,  depend on the smooth  functioning  of its computer
systems. Many computer software systems in use today cannot distinguish the year
2000 from the year 1900  because of the way dates are  encoded  and  calculated.
That failure could have a negative impact on handling securities trades, pricing
and account services.  IAI has been actively working on necessary changes to its
computer  systems to deal with the year 2000 and expects  that  systems  will be
adapted in time for that event, although there cannot be assurance of success.
    

     Shareholder  inquiries  should  be  directed  to the Fund at the  telephone
number or mailing address listed on the inside back cover of this Prospectus.

                        INVESTMENT OBJECTIVE AND POLICIES

     The  investment  objective  and policies of IAI Bond Fund (the "Bond Fund")
and IAI Government Fund ("Government  Fund") are summarized on the front page of
the Prospectus and in the text of the Prospectus  under  "Investment  Objectives
and Policies."  Investors  should  understand that all  investments  have a risk
factor.  There can be no guarantee  against loss resulting from an investment in
the Funds, and there can be no assurance that a Fund's investment  policies will
be successful, or that its investment objective will be attained. Certain of the
investment practices of the Funds are further explained below.

REPURCHASE AGREEMENTS

     The Funds may invest in repurchase agreements relating to the securities in
which it may invest. A repurchase  agreement involves the purchase of securities
with the condition that, after a stated period of time, the original seller will
buy back the securities at a  predetermined  price or yield. A Fund's  custodian
will have custody of, and will hold in a segregated account, securities acquired
by such Fund under a repurchase agreement or other securities as collateral.  In
the case of a security registered on a book entry system, the book entry will be
maintained  in a Fund's  name or that of its  custodian.  Repurchase  agreements
involve certain risks not associated with direct investments in securities.  For
example, if the seller of the agreement defaults on its obligation to repurchase
the  underlying  securities  at a time  when  the  value of the  securities  has
declined,  a Fund may incur a loss upon disposition of such  securities.  In the
event that  bankruptcy  proceedings  are commenced with respect to the seller of
the  agreement,  a Fund's  ability to dispose of the  collateral  to recover its
investment may be restricted or delayed.  While  collateral will at all times be
maintained  in an amount  equal to the  repurchase  price  under  the  agreement
(including  accrued  interest due  thereunder),  to the extent proceeds from the
sale of collateral  were less than the  repurchase  price, a Fund could suffer a
loss.

REVERSE REPURCHASE AGREEMENTS

     The  Funds  may  invest  in  reverse  repurchase  agreements  as a form  of
borrowing.  In  a  reverse  repurchase  agreement,  a  fund  sells  a  portfolio
instrument to another party, such as a bank or broker-dealer, in return for cash
and agrees to repurchase the instrument at a particular  price and time. While a
reverse repurchase  agreement is outstanding,  a Fund will maintain  appropriate
liquid assets in a segregated  custodial  account to cover its obligation  under
the agreement. The Funds will enter into reverse repurchase agreements only with
parties  whose  creditworthiness  has  been  found  satisfactory  by  Investment
Advisers,  Inc. ("IAI"), the Funds' investment adviser and manager. As a result,
such  transactions  may increase  fluctuations in the market value of the Fund's
assets  and may be viewed  as a form of  leverage.  The  Funds do not  currently
intend  to  invest  more  than  5% of  its  net  assets  in  reverse  repurchase
agreements.

SECURITIES OF FOREIGN ISSUERS

     Each of Bond and  Government  Funds may  invest in  securities  of  foreign
issuers in accordance with its investment objectives and policies.  Investing in
foreign securities may result in greater risk than that incurred by investing in
domestic  securities.  There is generally  less publicly  available  information
about foreign issuers comparable to reports and ratings that are published about
companies in the United States. Also, foreign issuers are not subject to uniform
accounting  and  auditing  and  financial  reporting  standards,  practices  and
requirements   comparable  to  those  applicable  to  United  States  companies.
Furthermore,  volume and  liquidity in most foreign bond markets is less than in
the United  States and at times  volatility  of price can be greater than in the
United States. There is generally less government  supervision and regulation of
foreign bond markets, brokers and companies than in the United States.

     With respect to certain  foreign  countries,  there is the  possibility  of
adverse changes in investment or exchange control regulations,  expropriation or
confiscatory taxation,  limitations on the removal of funds or other assets of a
Fund,  political or social instability,  or diplomatic  developments which could
affect  United  States  investments  in those  countries.  Moreover,  individual
foreign  economies may differ  favorably or unfavorably  from the United States'
economy in such respects as growth of gross national product, rate of inflation,
capital  reinvestment,   resource   self-sufficiency  and  balance  of  payments
position.

                                       2
<PAGE>

     Bond and  Government  Funds are not aware at this time of the  existence of
any investment or exchange control regulations which might substantially  impair
their operations as described in the Prospectus and this Statement of Additional
Information.  It should be noted,  however,  that this situation could change at
any time.

     The dividends and interest payable on certain of a Fund's foreign portfolio
securities may be subject to foreign  withholding  taxes,  thus reducing the net
amount of income  available for  distribution to such Fund's  shareholders.  The
expense  ratio  of a Fund  should  not be  materially  affected  by such  Fund's
investment in foreign securities.

U.S. TREASURY INFLATION PROTECTION SECURITIES

     Both the Bond Fund and the Government Fund may purchase  securities  issued
by   the   United   States    government,    which    include   U.S.    Treasury
inflation-protection securities.

     Inflation-protection   securities  are  a  type  of  marketable  book-entry
security issued by the United States Department of Treasury  ("Treasury") with a
nominal  return  linked to the  inflation  rate in prices.  Inflation-protection
securities are auctioned and issued on a quarterly basis on the 15th of January,
April,  July, and October.  They have been issued as 10-year  notes,  with other
maturities  added  thereafter.  The  index  used  to  measure  inflation  is the
non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All
Urban Consumers ("CPI-U").

     The value of the principal ia adjusted for inflation,  and every six months
the security will pay interest,  which is an amount equal to a fixed  percentage
of the inflation-adjusted value of the principal. The final payment of principal
of the security will not be less than the original par amount of the security at
issuance.

     The  principal  of the  inflation-protection  security  is  indexed  to the
non-seasonally  adjusted  CPI-U. To calculate the  inflation-adjusted  principal
value for a particular valuation date, the value of the principal at issuance is
multiplied by the index ratio applicable to that valuation date. The index ratio
for any date is the ratio of the  reference  CPI  applicable to such date to the
reference CPI applicable to the original issue date.  Semiannual coupon interest
is determined by multiplying the inflation-adjusted principal amount by one-half
of the stated rate of interest on each interest payment date.

     Inflation-adjusted  principal  or the  original  par amount,  whichever  is
larger,  will be paid  on the  maturity  date  as  specified  in the  applicable
offering announcement.  If at maturity the inflation-adjusted  principal is less
than the original  principal value of the security an additional  amount will be
paid at  maturity  so that the  additional  amount  plus the  inflation-adjusted
principal  equals  the  original  principal  amount.  Some  inflation-protection
securities may be stripped into principal and interest  components.  In the case
of a stripped security,  the holder of the stripped principal would receive this
additional  amount.  The final interest payment,  however,  will be based on the
final inflation-adjusted principal value, not the original par amount.

     The reference CPI for the first day of any calendar  month is the CPI-U for
the third preceding calendar month. (For example, the reference CPI for December
1 is the CPI-U  reported for  September  of the same year,  which is released in
October.)  The  reference  CPI for any other day of the month is calculated by a
linear  interpolation  between the reference CPI  applicable to the first day of
the month and the  reference  CPI  applicable  to the first day of the following
month.

                                       3
<PAGE>


     Any revisions the Bureau of Labor Statistics (or successor agency) makes to
any  CPI-U  number  that  has  been  previously  released  will  not be  used in
calculations of the value of outstanding inflation-protection securities. In the
case that the CPI-U for a  particular  month is not  reported by the last day of
the  following  month,  the Treasury  will announce an index number based on the
last  year-over-year  CPI-U  inflation rate available.  Any  calculations of the
Treasury's payment  obligations on the  inflation-protection  security that need
that  month's  CPI-U  number will be based on the index number that the Treasury
has  announced.  If the CPI-U is based to a different  year,  the Treasury  will
continue to use the CPI-U  series based on the base  reference  period in effect
when the  security  was first  issued  as long as that  series  continues  to be
published.    If   the   CPI-U   is   discontinued   during   the   period   the
inflation-protection security is outstanding, the Treasury will, in consultation
with  the  Bureau  of Labor  Statistics  (or  successor  agency),  determine  an
appropriate substitute index and methodology for linking the discontinued series
with the new price index series. Determinations of the Secretary of the Treasury
in this regard are final.

     Inflation-protection  securities  will be held and transferred in either of
two book-entry systems:  the commercial  book-entry system (TRADES) and TREASURY
DIRECT.  The securities will be maintained and transferred at their original par
amount, i.e., not at their  inflation-adjusted  value. STRIPS components will be
maintained  and  transferred  in TRADES at their value based on the original par
amount of the fully constituted security.

LENDING PORTFOLIO SECURITIES

     In order to  generate  additional  income,  the  Funds  may lend  portfolio
securities to broker-dealers,  banks or other financial borrowers of securities.
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,  a Fund  will only  enter  into  loan  arrangements  with
broker-dealers,  banks  or  other  institutions  which  IAI has  determined  are
creditworthy under guidelines established by the Funds' Board of Directors.  The
Funds may also  experience  a loss if,  upon the failure of a borrower to return
loaned  securities,  the  collateral is not  sufficient in value or liquidity to
cover the value of such loaned securities  (including accrued interest thereon).
However,  a Fund will  receive  collateral  in the form of cash,  United  States
Government securities,  certificates of deposit or other high-grade,  short-term
obligations or  interest-bearing  cash equivalents equal to at least 102% of the
value  of  the  securities  loaned.  The  value  of  the  collateral  and of the
securities  loaned  will be marked to market on a daily  basis.  During the time
portfolio  securities are on loan, the borrower pays a Fund an amount equivalent
to any  dividends or interest paid on the  securities  and a Fund may invest the
cash collateral and earn additional  income or may receive an agreed upon amount
of interest income from the borrower.  However,  the amounts  received by a Fund
may be reduced by finders' fees paid to broker-dealers and related expenses.

ILLIQUID SECURITIES

     Each Fund may also  invest up to 15% of its net assets in  securities  that
are considered  illiquid because of the absence of a readily available market or
due to legal or contractual restrictions. However, certain restricted securities
that are not  registered  for sale to the  general  public that can be resold to
institutional  investors may be considered liquid pursuant to guidelines adopted
by the Board of Directors. In the case of a Rule 144A Security, such security is
deemed to be liquid if:

     (1) IAI reasonably expects to be able to resell the security to a qualified
institutional  buyer, as defined in paragraph  (a)(1) of Rule 144A, who is aware
of  the  Fund's  reliance  upon  Rule  144A  in  selling  the  security  without
registration, as required by paragraph (d)(2) of Rule 144A;

     (2) the  Rule  144A  Security  is not (a) of the same  class as  securities
listed on any  national  securities  exchange or quoted in NASDAQ as  determined
under  paragraph  (d)(3)(i)  of Rule  144A,  or (b) a security  of a  registered
investment company (other than a closed-end investment company); and

                                       4
<PAGE>


     (3) the issuer (a) is a foreign government  eligible to register securities
under  Schedule B of the  Securities  Act of 1933,  (b) is a company  that files
periodic  reports under the Securities  Act of 1934 on Forms 8-K, 10-Q,  10-K or
20-F or provides information under Rule 12g3-2(b) thereunder,  or (c) has agreed
in writing to provide the holder and any prospective  purchaser of the Rule 144A
Security  with  reasonably  current  financial  information  as  required  under
paragraph (d)(4)(i) of Rule 144A.

     Other  securities  are  deemed  to be  liquid  if IAI  determines  that the
security can be disposed of within seven days in the ordinary course of business
at  approximately  the amount at which the Funds have valued the  instrument for
purposes of calculating a Fund's net asset value. In making this  determination,
IAI will consider such factors as may be relevant to a Fund's ability to dispose
of the security,  including  but not limited to, the following  factors (none of
which, standing alone, would necessarily be determinative):

     1. the frequency of trades and quotes for the security;

     2. the number of dealers  willing to purchase or sell the  security and the
number of potential purchasers;

     3. dealer undertakings to make a market in the security; and

     4. the  nature of the  security  and the nature of the  marketplace  trades
(e.g.,  the time  needed to dispose of the  security,  the method of  soliciting
offers and the mechanics of transfer).

     It is  not  possible  to  predict  with  assurance  the  maintenance  of an
institutional  trading market for such  securities and the liquidity of a Fund's
investments could be impaired if trading declines.

VARIABLE OR FLOATING RATE INSTRUMENTS

     Each  Fund may  invest in  variable  or  floating  rate  instruments.  Such
instruments  (including notes purchased  directly from issuers) bear variable or
floating  interest  rates and carry rights that permit holders to demand payment
of the unpaid  principal  balance  plus  accrued  interest  from the  issuers or
certain financial  intermediaries.  Floating rate securities have interest rates
that change  whenever there is a change in a designated base rate while variable
rate  instruments  provide for a specified  periodic  adjustment in the interest
rate. These formulas are designed to result in a market value for the instrument
that approximates its par value.

DELAYED-DELIVERY TRANSACTIONS

     Each Fund may buy and sell securities on a delayed-delivery  or when-issued
basis.  These  transactions  involve a commitment  by a Fund to purchase or sell
specific securities at a predetermined price or yield, with payment and delivery
taking  place after the  customary  settlement  period for that type of security
(and more than seven days in the future).  Typically, no interest accrues to the
purchaser  until the  security  is  delivered.  Each Fund may  receive  fees for
entering into delayed-delivery transactions.

     When purchasing  securities on a delayed-delivery  basis, each Fund assumes
the  rights  and  risks of  ownership,  including  the risk of price  and  yield
fluctuations.  Because a Fund is not  required to pay for  securities  until the
delivery  date,  these risks are in addition to the risks  associated  with such
Fund's other investments.  If a Fund remains  substantially  fully invested at a
time when delayed  delivery  purchases  are  outstanding,  the  delayed-delivery
purchases may result in a form of leverage. When delayed-delivery  purchases are
outstanding,  a Fund will set aside  appropriate  liquid  assets in a segregated
custodial  account  to cover its  purchase  obligations.  When a Fund has sold a
security on a delayed-delivery  basis, such Fund does not participate in further
gains  or  losses  with  respect  to the  security.  If  the  other  party  to a
delayed-delivery  transaction fails to deliver or pay for the securities, a Fund
could miss a favorable price or yield opportunity, or could suffer a loss.

     Each Fund may  renegotiate  delayed-delivery  transactions  after  they are
entered into,  and may sell  underlying  securities  before they are  delivered,
which may result in capital gains or losses.

                                       5
<PAGE>


DOLLAR ROLLS

     In connection  with its ability to purchase  securities on a when-issued or
forward  commitment  basis,  a Fund may enter into "dollar  rolls" in which such
Fund sells  securities  for  delivery  in the current  month and  simultaneously
contracts with the same  counterparty to repurchase  similar (same type,  coupon
and maturity) but not  identical  securities on a specified  future date. A Fund
gives up the right to receive  principal  and  interest  paid on the  securities
sold.  However, a Fund would benefit to the extent of any difference between the
price received for the  securities  sold and lower forward price for the futures
purchase plus any fee income  received.  Unless such benefits  exceed the income
and capital appreciation that would have been realized on the securities sold as
part of the dollar roll,  the use of this technique will diminish the investment
performance  of a Fund  compared  with what  such  performance  would  have been
without  the use of  dollar  rolls.  Each  Fund  will  hold  and  maintain  in a
segregated  account until the settlement date cash,  government  securities,  or
liquid  high-grade  debt  securities  in an  amount  equal  to the  value of the
when-issued or forward commitment securities.  The benefits derived from the use
of dollar rolls may depend,  among other  things,  upon IAI's ability to predict
interest  rates  correctly.  There is no  assurance  that  dollar  rolls  can be
successfully  employed.  In  addition,  the use of dollar  rolls by a Fund while
remaining  substantially  fully invested increases the amount of a Fund's assets
that are subject to market  risk to an amount  that is greater  than such Fund's
net asset value, which could result in increased volatility of the price of such
Fund's shares.

MORTGAGE-BACKED SECURITIES

     Each Fund may purchase mortgage-backed  securities issued by government and
non-government  entities such as banks,  mortgage  lenders,  or other  financial
institutions.  A  mortgage-backed  security may be an  obligation  of the issuer
backed by a mortgage or pool of mortgages or a direct  interest in an underlying
pool of  mortgages.  Some  mortgage-backed  securities,  such as  collateralized
mortgage  obligations or CMOs, make payments of both principal and interest at a
variety  of  intervals;   others  make   semiannual   interest   payments  at  a
predetermined  rate and repay  principal  at  maturity  (like a  typical  bond).
Mortgage-backed  securities are based on different types of mortgages  including
those on  commercial  real  estate or  residential  properties.  Other  types of
mortgage-backed  securities  will likely be developed in the future,  and a Fund
may  invest in them if IAI  determines  they are  consistent  with  such  Fund's
investment objective and policies.

     The value of  mortgage-backed  securities  may  change due to shifts in the
market's  perception  of issuers.  In  addition,  regulatory  or tax changes may
adversely  affect  the  mortgage  securities  market as a whole.  Non-government
mortgage-backed  securities  may  offer  higher  yields  than  those  issued  by
government  entities,  but also may be  subject to greater  price  changes  than
government  issues.  Mortgage-backed  securities are subject to prepayment risk.
Prepayment,  which  occurs when  unscheduled  or early  payments are made on the
underlying  mortgages,  may shorten the effective maturities of these securities
and may lower their total returns.

STRIPPED MORTGAGE-BACKED SECURITIES

     Government   and  Bond  Funds  may  invest  in   stripped   mortgage-backed
securities.  Such  securities  are created  when a U.S.  government  agency or a
financial  institution  separates  the interest and  principal  components  of a
mortgage-backed security and sells them as individual securities.  The holder of
the  "principal-only"  security (PO) receives the principal payments made by the
underlying  mortgage-backed  security,  while the holder of the  "interest-only"
security (IO) receives interest payments from the same underlying security.  The
prices of stripped  mortgage-backed  securities may be particularly  affected by
changes in interest  rates.  As interest  rates fall,  prepayment  rates tend to
increase, which tends to reduce prices of IOs and increase prices of POs. Rising
interest rates can have the opposite effect.

                                       6
<PAGE>


ASSET-BACKED SECURITIES

     Government and Bond Funds may invest in stripped  asset-backed  securities.
Asset-backed   securities   represent  interests  in  pools  of  consumer  loans
(generally  unrelated  to  mortgage  loans)  and most  often are  structured  as
pass-through securities. Interest and principal payments alternately depend upon
payment of the underlying  loans by individuals,  although the securities may be
supported  by  letters  of credit  or other  credit  enhancements.  The value of
asset-backed securities may also depend on the creditworthiness of the servicing
agent  for  the  loan  pool,  the  originator  of the  loans,  or the  financial
institution providing the credit enhancement.

ZERO COUPON BONDS

     Each Fund may invest in zero coupon  bonds.  Zero coupon  bonds do not make
interest  payments;  instead,  they are sold at a deep  discount from their face
value and are redeemed at face value when they mature. Because zero coupon bonds
do not pay current income, their prices can be very volatile when interest rates
change.  In  calculating  its  dividends,  a Fund takes into account as income a
portion of the  difference  between a zero coupon bond's  purchase price and its
face value.

     A  broker-dealer  creates a derivative  zero by separating the interest and
principal  components  of a U.S.  Treasury  security  and  selling  them  as two
individual  securities.  CATS (Certificates of Accrual on Treasury  Securities),
TIGRs (Treasury  Investment  Growth Receipts),  and TRs (Treasury  Receipts) are
examples of derivative zeros.

     The Federal  Reserve Bank creates  STRIPS  (Separate  Trading of Registered
Interest and Principal of  Securities)  by separating the interest and principal
components of an outstanding  U.S.  Treasury bond and selling them as individual
securities. Bonds issued by the Resolution Funding Corporation (REFCORP) and the
Financing  Corporation  (FICO) can also be separated in this  fashion.  Original
issue  zeroes  are  zero  coupon  securities   originally  issued  by  the  U.S.
government, a government agency, or a corporation in zero coupon form.

LOWER-RATED DEBT SECURITIES

     Issuers of high yield  securities may be highly  leveraged and may not have
available to them more traditional  methods of financing.  Therefore,  the risks
associated  with acquiring the securities of such issuers  generally are greater
than is the case with higher rated securities.  For example,  during an economic
downturn or a sustained  period of rising interest rates,  issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly  leveraged.  During such  periods,  such issuers may not have
sufficient  revenues to meet their interest  payment  obligations.  The issuer's
ability  to service  its debt  obligations  also may be  adversely  affected  by
specific  issuer  developments  or  the  issuer's  inability  to  meet  specific
projected business forecasts or the unavailability of additional financing.  The
risk of loss due to  default  by the  issuer is  significantly  greater  for the
holders of high yield  securities  because such  securities may be unsecured and
may be subordinated to other creditors of the issuer.

     High yield  securities  frequently  have call or redemption  features which
would permit an issuer to  repurchase  the security  from a Fund. If a call were
exercised by the issuer  during a period of  declining  interest  rates,  a Fund
likely  would  have to  replace  such  called  security  with a  lower  yielding
security,  thus decreasing the net investment  income to a Fund and dividends to
shareholders.

     A Fund may have  difficulty  disposing  of certain  high  yield  securities
because there may be a thin trading  market for such  securities.  The secondary
trading  market  for high yield  securities  is  generally  not as liquid as the
secondary market for higher rated securities. Reduced secondary market liquidity
may have an adverse  impact on market  price and a Fund's  ability to dispose of
particular  issues  when  necessary  to meet such Fund's  liquidity  needs or in
response  to  a  specific   economic  event  such  as  a  deterioration  in  the
creditworthiness of the issuer.

                                       7
<PAGE>


     Adverse  publicity  and  investor  perceptions,  which  may not be based on
fundamental  analysis,  also may decrease the value and  liquidity of high yield
securities,  particularly in a thinly traded market. Factors adversely affecting
the market  value of high yield  securities  are  likely to  adversely  affect a
Fund's net asset value. In addition, a Fund may incur additional expenses to the
extent it is required to seek recovery upon a default on a portfolio  holding or
participate in the restructuring of the obligation.

SWAP AGREEMENTS

     Each  Fund  may  enter  into  swap  agreements.   Swap  agreements  can  be
individually  negotiated  and  structured  to include  exposure  to a variety of
different types of investments or market factors.  Depending on their structure,
swap  agreements  may  increase  or  decrease  a  Fund's  exposure  to  long- or
short-term  interest  rates (in the U.S. or abroad),  foreign  currency  values,
mortgage  securities,  corporate  borrowing  rates,  or  other  factors  such as
security  prices or inflation  rates.  Swap  agreements  can take many different
forms  and are  known  by a  variety  of  names.  A Fund is not  limited  to any
particular  form of swap agreement if IAI determines it is consistent  with such
Fund's investment objectives and policies.

     Swap  agreements will tend to shift a Fund's  investment  exposure from one
type of  investment  to  another.  For  example,  if a Fund  agrees to  exchange
payments in dollars for payments in foreign  currency,  the swap agreement would
tend to  decrease a Fund's  exposure to U.S.  interest  rates and  increase  its
exposure to foreign currency and interest rates. Depending on how they are used,
swap  agreements  may  increase or decrease the overall  volatility  of a Fund's
investments and its share price.

     The most  significant  factor in the  performance of swap agreements is the
change in the specific interest rate, currency,  or other factors that determine
the amounts of payments due to and from a Fund.  If a swap  agreement  calls for
payments by a Fund,  such Fund must be prepared to make such  payments when due.
In addition,  if the counterparty's  creditworthiness  declined,  the value of a
swap agreement would be likely to decline, potentially resulting in losses. Each
Fund expects to be able to eliminate its exposure under swap  agreements  either
by assignment  or other  disposition,  or by entering  into an  offsetting  swap
agreement with the same party or a similarly creditworthy party.

     Each Fund will maintain appropriate liquid assets in a segregated custodial
account to cover its current obligations under swap agreements. If a Fund enters
into a swap  agreement  on a net basis,  it will  segregate  assets with a daily
value at least equal to the excess,  if any, of such Fund's accrued  obligations
under the swap  agreement  over the  accrued  amount  such Fund is  entitled  to
receive  under the  agreement.  If a Fund enters into a swap  agreement on other
than a net basis, it will segregate assets with a value equal to the full amount
of such Fund's accrued obligations under the agreement.

INDEXED SECURITIES

     Bond and Government Funds may purchase  securities whose prices are indexed
to the prices of other  securities,  securities  indexes,  currencies,  precious
metals or other commodities,  or other financial indicators.  Indexed securities
typically,  but not  always,  are debt  securities  or  deposits  whose value at
maturity or coupon rate is determined  by reference to a specific  instrument or
statistic.  Gold-indexed  securities,  for  example,  typically  provide  for  a
maturity value that depends on the price of gold,  resulting in a security whose
price  tends  to rise and  fall  together  with  gold  prices.  Currency-indexed
securities typically are short-term to  intermediate-term  debt securities whose
maturity  values or interest  rates are determined by reference to the values of
one or more specified foreign currencies,  and may offer higher yields than U.S.
dollar-denominated securities of equivalent issuers. Currency-indexed securities
may be positively  or  negatively  indexed;  that is, their  maturity  value may
increase when the specified  currency value  increases,  resulting in a security
that performs similarly to a foreign-denominated  instrument,  or their maturity
value may decline  when  foreign  currencies  increase,  resulting in a security
whose price  characteristics  are similar to a put on the  underlying  currency.
Currency-indexed  securities may also have prices that depend on the values of a
number of different foreign currencies relative to each other.

                                       8
<PAGE>


     The  performance  of indexed  securities  depends to a great  extent on the
performance  of the security,  currency,  or other  instrument to which they are
indexed,  and may also be  influenced  by interest  rate changes in the U.S. and
abroad.  At the same time,  indexed  securities  are subject to the credit risks
associated  with the  issuer of the  security,  and  their  values  may  decline
substantially if the issuer's creditworthiness  deteriorates.  Recent issuers of
indexed  securities  have  included  banks,   corporations,   and  certain  U.S.
government  agencies.  IAI will use its judgment in determining  whether indexed
securities should be treated as short-term  instruments,  bonds, stocks, or as a
separate asset class for purposes of a Fund's investment policies,  depending on
the individual characteristics of the securities. Indexed securities may be more
volatile than the underlying instruments.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS

     Bond and  Government  Funds  may  invest in loans  and  other  direct  debt
instruments.  Direct  debt  instruments  are  interests  in  amounts  owed  by a
corporate,  governmental,  or other  borrower  to lenders or lending  syndicates
(loans and loan participations), to suppliers of goods or services (trade claims
or other receivable),  or to other parties.  Direct debt instruments are subject
to a Fund's policies regarding the quality of debt securities.

     Purchasers of loans and other forms of direct indebtedness depend primarily
upon the creditworthiness of the borrower for payment of principal and interest.
Direct debt  instruments  may not be rated by any nationally  recognized  rating
service.  If a Fund does not receive scheduled interest or principal payments on
such indebtedness,  a Fund's share price and yield could be adversely  affected.
Loans that are fully secured offer a Fund more protection than an unsecured loan
in the event of non-payment of scheduled interest or principal.  However,  there
is no assurance  that the  liquidation  of collateral  from a secured loan would
satisfy the  borrower's  obligation,  or that the  collateral can be liquidated.
Indebtedness of borrowers whose  creditworthiness is poor involves substantially
greater risks, and may be highly  speculative.  Borrowers that are in bankruptcy
or restructuring may never pay off their  indebtedness,  or may pay only a small
fraction of the amount owed.  Direct  indebtedness of developing  countries will
also involve a risk that the governmental entities responsible for the repayment
of the debt may be unable,  or  unwilling,  to pay interest and repay  principal
when due.

     Investments in loans through direct assignment of a financial institution's
interests  with respect to a loan may involve  additional  risks to a Fund.  For
example,  if a loan  is  foreclosed,  a Fund  could  become  part  owner  of any
collateral,  and would bear the costs and liabilities associated with owning and
disposing of the collateral.  In addition, it is conceivable that under emerging
legal theories of lender liability,  a Fund could be held liable as a co-lender.
Direct debt  instruments  may also involve a risk of  insolvency  of the lending
bank or other  intermediaries.  Direct debt instruments that are not in the form
of securities may offer less legal  protection to the Fund in the event of fraud
or  misrepresentation.  In the absence of definitive regulatory guidance, a Fund
relies on IAI's  research  in an  attempt  to avoid  situations  where  fraud or
misrepresentation could adversely affect such Fund.

     A loan is often administered by a bank or other financial  institution that
acts as agent for all holders.  The agent  administers the terms of the loan, as
specified in the loan  agreement.  Unless,  under the terms of the loan or other
indebtedness,  a Fund has direct recourse  against the borrower,  it may have to
rely on the agent to apply  appropriate  credit remedies against a borrower.  If
assets held by the agent for the benefit of a Fund were determined to be subject
to the claims of the agent's  general  creditors,  such Fund might incur certain
costs and  delays in  rendering  payment on the loan or loan  participation  and
could suffer a loss of principal or interest.

     Bond and  Government  Funds limit the amount of the assets that they invest
in any one issuer or in issuers within the same industry.  For purposes of these
limitations,  a Fund  generally  will  treat the  borrower  as the  "issuer"  of
indebtedness held by such Fund. In the case of loan participations  where a bank
or other lending institution serves as financial intermediary between a Fund and
the  borrower,  if the  participation  does not  shift to such  Fund the  direct
debtor/creditor relationship with the borrower, SEC interpretations require such
Fund,  in  appropriate  circumstances,  to treat both the lending  bank or other
lending institution and the borrower as "issuers" for the purpose of determining
whether  such Fund has  invested  more  than 5% of its total  assets in a single
issuer.  Treating the financial  intermediary as an issuer of  indebtedness  may
restrict  a  Fund's  ability  to  invest  in  indebtedness  related  to a single
financial  intermediary,  or a  group  of  intermediaries  engaged  in the  same
industry,  even if the underlying  borrowers  represent many different companies
and industries.

EXTENDIBLE NOTES

     Government  Fund is permitted to invest in  extendible  notes in accordance
with its  investment  objectives  and  policies.  An  extendible  note is a debt
arrangement  under  which the holder,  at its option,  may require the issuer to
repurchase the note for a  predetermined  fixed price at one or more times prior
to the ultimate  maturity date of the note.  Typically,  an  extendible  note is
issued at an interest  rate that can be adjusted at fixed times  throughout  its
term.  At the same times as the  interest  rate is adjusted  by the issuer,  the
holder of the note is  typically  given the option to "put" the note back to the
issuer at a  predetermined  price (e.g.,  at 100% of the  outstanding  principal
amount  plus  unpaid  accrued   interest)  if  the  extended  interest  rate  is
undesirable to the holder. This option to put the note back to the issuer (i.e.,
to require  the  issuer to  repurchase  the note)  provides  the holder  with an
optional  maturity  date that is shorter  than the actual  maturity  date of the
note.

     Extendible  notes may be issued with maturity  dates in excess of ten years
from the date of issuance.  However,  if such  extendible  notes  provide for an
optional  maturity  date of ten  years or less,  then such  notes are  deemed by
Government  Fund to have been issued for the  shorter  optional  maturity  date.
Investment in extendible  notes is not expected to have a material impact on the
effective portfolio maturity of Government Fund.

     An investment in an extendible  note is liquid,  and the note may be resold
to another investor prior to its optional maturity date at its market value. The
market  value of an  extendible  note  with a given  optional  maturity  date is
determined  and  fluctuates  in a similar  manner as the market value of a fixed
maturity  note  with a  maturity  equivalent  to the  optional  maturity  of the
extendible  note.  Compared  to fixed  term notes of the same  issuer,  however,
extendible  notes with  equivalent  optional  maturities  generally yield higher
returns without a material increase in risk to Government Fund.

     The  creditworthiness  of the issuers of extendible  notes is monitored and
rated by  Moody's  and by S&P.  The  creditworthiness  of such  issuers  is also
monitored by IAI. Government Fund does not have a current intention of investing
in the coming year more than 5% of its net assets in extendible notes.

FOREIGN CURRENCY TRANSACTIONS

     Bond and Government Funds may hold foreign  currency  deposits from time to
time and may  convert  dollars and foreign  currencies  in the foreign  exchange
markets.  Currency conversion involves dealer spreads and other costs,  although
commissions  usually are not  charged.  Currencies  may be  exchanged  on a spot
(i.e.,  cash) basis,  or by entering into forward  contracts to purchase or sell
foreign currencies at a future date and price.  Forward contracts  generally are
traded in an  interbank  market  conducted  directly  between  currency  traders
(usually large commercial  banks) and their customers.  The parties to a forward
contract may agree to offset or terminate the contract  before its maturity,  or
may hold the  contract  to  maturity  and  complete  the  contemplated  currency
exchange.

     Such Funds may use currency forward  contracts to manage currency risks and
to facilitate  transactions  in foreign  securities.  The  following  discussion
summarizes  the  principal  currency  management  strategies  involving  forward
contracts that could be used by the Funds.

     In connection with purchases and sales of securities denominated in foreign
currencies,  a Fund may enter into currency forward  contracts to fix a definite
price for the purchase or sale in advance of the trade's  settlement  date. This
technique  is  sometimes  referred to as a  "settlement  hedge" or  "transaction
hedge."  IAI  expects to enter into  settlement  hedges in the normal  course of
managing a Fund's  foreign  investments.  A Fund  could also enter into  forward
contracts  to purchase  or sell a foreign  currency  in  anticipation  of future
purchases or sales of securities  denominated in foreign  currency,  even if the
specific investments have not yet been selected by IAI.

                                       10
<PAGE>


     Each Fund may also use forward  contracts to hedge against a decline in the
value of existing investments denominated in foreign currency. For example, if a
Fund owned  securities  denominated  in pounds  sterling,  it could enter into a
forward  contract  to sell pounds  sterling in return for U.S.  dollars to hedge
against possible declines in the pound's value. Such a hedge, sometimes referred
to as a  "position  hedge,"  would tend to offset  both  positive  and  negative
currency  fluctuations but would not offset changes in security values caused by
other factors.  A Fund could also hedge the position by selling another currency
expected to perform similarly to the pound sterling -- for example,  by entering
into a forward  contract to sell  Deutschemarks  or European  Currency  Units in
return for U.S. dollars.  This type of hedge,  sometimes referred to as a "proxy
hedge,"  could offer  advantages in terms of cost,  yield,  or  efficiency,  but
generally  would not hedge  currency  exposure as  effectively as a simple hedge
into U.S.  dollars.  Proxy hedges may result in losses if the  currency  used to
hedge does not perform  similarly to the currency in which the hedged securities
are denominated.

     Under certain conditions,  SEC guidelines require mutual funds to set aside
appropriate  liquid assets in a segregated  custodial  account to cover currency
forward  contracts.  As required  by SEC  guidelines,  each Fund will  segregate
assets to cover currency forward contracts, if any, whose purpose is essentially
speculative.  Each Fund will not  segregate  assets to cover  forward  contracts
entered into for hedging purposes, including settlement hedges, position hedges,
and proxy hedges.

     Successful use of forward currency  contracts will depend on IAI's skill in
analyzing and predicting  currency values.  Forward  contracts may substantially
change a Fund's  investment  exposure to changes in currency exchange rates, and
could  result  in  losses  to a  Fund  if  currencies  do  not  perform  as  IAI
anticipates.  For  example,  if a  currency's  value rose at a time when IAI had
hedged a Fund by selling that currency in exchange for dollars,  such Fund would
be unable to participate in the currency's appreciation.  If IAI hedges currency
exposure  through proxy hedges,  a Fund could realize  currency  losses from the
hedge and the security  position at the same time if the two  currencies  do not
move in tandem.  Similarly,  if IAI  increases  a Fund's  exposure  to a foreign
currency,  and that currency's  value  declines,  such Fund will realize a loss.
There is no  assurance  that IAI's use of  forward  currency  contracts  will be
advantageous  to a Fund or  that  it will  hedge  at an  appropriate  time.  The
policies described in this section are non-fundamental policies of the Funds.

LIMITATIONS ON FUTURES AND OPTIONS TRANSACTIONS

     Each  Fund  has  filed a  notice  of  eligibility  for  exclusion  from the
definition of the term  "commodity  pool  operator"  with the Commodity  Futures
Trading Commission (CFTC) and the National Futures  Association,  which regulate
trading in the futures  markets,  before  engaging in any  purchases or sales of
futures contracts or options on futures  contracts.  Each Fund intends to comply
with Section 4.5 of the  regulations  under the Commodity  Exchange  Act,  which
limits the extent to which a Fund can commit assets to initial  margin  deposits
and option premiums.

     The above  limitations  on a Fund's  investments  in futures  contracts and
options,  and such  Fund's  policies  regarding  futures  contracts  and options
discussed  elsewhere in this Statement of Additional  Information may be changed
as regulatory agencies permit. With respect to positions in commodity futures or
commodity  option  contracts  which do not come within the meaning and intent of
bona fide hedging in the CFTC rules,  the aggregate  initial margin and premiums
required  to  establish  such  positions  will not  exceed  five  percent of the
liquidation  value of a Fund's portfolio,  after taking into account  unrealized
profits and unrealized  losses on any such  contracts it has entered into;  and,
provided  further,  that in the case of an  option  that is  in-the-money,  such
amount may be excluded in computing such 5 percent.

FUTURES CONTRACTS

     When a Fund purchases a futures contract, it agrees to purchase a specified
underlying  instrument at a specified  future date.  When a Fund sells a futures
contract,  it agrees to sell the  underlying  instrument  at a specified  future
date.  The price at which the  purchase and sale will take place is fixed when a
Fund enters into the contract.  Some currently  available  futures contracts are
based on specific securities, such as U.S. Treasury bonds or notes, and some are
based on  indexes  of  securities  prices,  such as the  Standard  & Poor's  500
Composite Stock Price Index (S&P 500).  Futures can be held until their delivery
dates,  or can be  closed  out  before  then if a  liquid  secondary  market  is
available.

                                       11
<PAGE>

     The value of a futures  contract  tends to increase  and decrease in tandem
with the  value of its  underlying  instrument.  Therefore,  purchasing  futures
contracts will tend to increase a Fund's exposure to positive and negative price
fluctuations  in the  underlying  instrument,  much as if it had  purchased  the
underlying  instrument  directly.  When a Fund  sells  a  futures  contract,  by
contrast,  the value of its  futures  position  will tend to move in a direction
contrary to the  market.  Selling  futures  contracts,  therefore,  will tend to
offset  both  positive  and  negative  market  price  changes,  much  as if  the
underlying instrument had been sold.

FUTURES MARGIN PAYMENTS

     The purchaser or seller of a futures contract is not required to deliver or
pay for the underlying instrument unless the contract is held until the delivery
date.  However,  both the purchaser and seller are required to deposit  "initial
margin" with a futures  broker,  known as a futures  commission  merchant (FCM),
when the contract is entered into.  Initial margin  deposits are typically equal
to a percentage of the contract's value. If the value of either party's position
declines,  that party will be required  to make  additional  "variation  margin"
payments  to settle the change in value on a daily  basis.  The party that has a
gain may be  entitled to receive  all or a portion of this  amount.  Initial and
variation margin payments do not constitute  purchasing securities on margin for
purposes of a Fund's investment  limitations.  In the event of the bankruptcy of
an FCM that  holds  margin  on behalf of a Fund,  such Fund may be  entitled  to
return of margin  owed to it only in  proportion  to the amount  received by the
FMC's other customers, potentially resulting in losses to such Fund.

PURCHASING PUT AND CALL OPTIONS

     By  purchasing  a put  option,  a Fund  obtains  the  right  (but  not  the
obligation) to sell the option's underlying  instrument at a fixed strike price.
In return for this right,  a Fund pays the current  market  price for the option
(known  as the  option  premium).  Options  have  various  types  of  underlying
instruments,  including specific  securities,  indexes of securities prices, and
futures  contracts.  A Fund may  terminate  its  position in a put option it has
purchased by allowing it to expire or by exercising the option. If the option is
allowed  to  expire,  a Fund will lose the  entire  premium  it paid.  If a Fund
exercises the option, it completes the sale of the underlying  instrument at the
strike price. A Fund may also terminate a put option  position by closing it out
in the  secondary  market at its current  price,  if a liquid  secondary  market
exists.

     The buyer of a typical  put option can expect to realize a gain if security
prices fall substantially.  However,  if the underlying  instrument's price does
not fall enough to offset the cost of  purchasing  the  option,  a put buyer can
expect to suffer a loss (limited to the amount of the premium paid, plus related
transaction costs).

     The  features  of call  options  are  essentially  the same as those of put
options,  except  that the  purchaser  of a call  option  obtains  the  right to
purchase,  rather than sell,  the underlying  instrument at the option's  strike
price.  A call buyer  typically  attempts  to  participate  in  potential  price
increases  of the  underlying  instrument  with risk  limited to the cost of the
option if security prices fall. At the same time, the buyer can expect to suffer
a loss if  security  prices do not rise  sufficiently  to offset the cost of the
option.

WRITING PUT AND CALL OPTIONS

     When a Fund  writes  a put  option,  it  takes  the  opposite  side  of the
transaction from the option's  purchaser.  In return for receipt of the premium,
such Fund  assumes  the  obligation  to pay the  strike  price for the  option's
underlying  instrument if the other party to the option  chooses to exercise it.
When  writing an option on a futures  contract a Fund would be  required to make
margin payments to an FCM as described above for futures  contracts.  A Fund may
seek to  terminate  its  position in a put option it writes  before  exercise by
closing  out the option in the  secondary  market at its current  price.  If the
secondary  market is not liquid for a put  option a Fund has  written,  however,
such Fund must  continue to be prepared to pay the strike price while the option
is  outstanding,  regardless  of price  changes,  and must continue to set aside
assets to cover its  position.  If  security  prices  rise,  a put writer  would
generally expect to profit,  although its gain would be limited to the amount of
the premium it received.

                                       12
<PAGE>


     If security  prices remain the same over time, it is likely that the writer
will also  profit,  because it should be able to close out the option at a lower
price.  If security  prices fall,  the put writer would expect to suffer a loss.
This loss should be less than the loss from purchasing the underlying instrument
directly,  however,  because the premium  received for writing the option should
mitigate the effects of the decline.

     Writing a call  option  obligates  a Fund to sell or deliver  the  option's
underlying  instrument,  in return for the strike  price,  upon  exercise of the
option.  The  characteristics  of writing  call  options are similar to those of
writing put  options,  except  that  writing  calls  generally  is a  profitable
strategy  if prices  remain  the same or falls.  Through  receipt  of the option
premium,  a call writer  mitigates the effects of a price  decline.  At the same
time,  because  a call  writer  must  be  prepared  to  deliver  the  underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.

COMBINED POSITIONS

     Each Fund may purchase and write options in combination with each other, or
in combination with futures or forward contracts,  to adjust the risk and return
characteristics of the overall position.  For example, a Fund may purchase a put
option and write a call option on the same  underlying  instrument,  in order to
construct a combined position whose risk and return  characteristics are similar
to selling a futures contract.  Another possible combined position would involve
writing a call  option at one strike  price and buying a call  option at a lower
price,  in order to reduce the risk of the written call option in the event of a
substantial price increase.  Because combined options positions involve multiple
trades,  they result in higher  transaction  costs and may be more  difficult to
open and close out.

CORRELATION OF PRICE CHANGES

     Because there are a limited number of types of exchange-traded  options and
futures contracts,  it is likely that the standardized  contracts available will
not match a Fund's current or  anticipated  investments  exactly.  Each Fund may
invest in options and  futures  contracts  based on  securities  with  different
issuers,  maturities,  or other  characteristics from the securities in which it
typically  invests,  which involves a risk that the options or futures  position
will not track the performance of such Fund's other investments.

     Options  and  futures  prices  can also  diverge  from the  prices of their
underlying  instruments,  even if the  underlying  instruments  match  a  Fund's
investments  well.  Options and futures  prices are  affected by such factors as
current and anticipated  short-term interest rates, changes in volatility of the
underlying instrument,  and the time remaining until expiration of the contract,
which may not affect  security  prices the same way.  Imperfect  correlation may
also result from differing  levels of demand in the options and futures  markets
and the  securities  markets,  from  structural  differences  in how options and
futures and securities are traded, or from imposition of daily price fluctuation
limits or  trading  halts.  A Fund may  purchase  or sell  options  and  futures
contracts  with a greater or lesser value than the securities it wishes to hedge
or intends to  purchase in order to attempt to  compensate  for  differences  in
volatility  between the contract and the  securities,  although  this may not be
successful  in all  cases.  If price  changes  in a Fund's  options  or  futures
positions are poorly  correlated with its other  investments,  the positions may
fail to  produce  anticipated  gains or result in losses  that are not offset by
gains in other investments.

LIQUIDITY OF OPTIONS AND FUTURES CONTRACTS

     There  is no  assurance  a  liquid  secondary  market  will  exist  for any
particular  options or futures contract at any particular time. Options may have
relatively low trading volume and liquidity if their strike prices are not close
to the  underlying  instrument's  current  price.  In  addition,  exchanges  may
establish daily price fluctuation limits for options and futures contracts,  and
may halt  trading if a contract's  price moves upward or downward  more than the
limit in a given day. On volatile trading days when the price  fluctuation limit
is reached or a trading  halt is  imposed,  it may be  impossible  for a Fund to
enter into new  positions  or close out  existing  positions.  If the  secondary
market for a  contract  is not liquid  because  of price  fluctuation  limits or
otherwise,  it could prevent prompt  liquidation of unfavorable  positions,  and
potentially  could require a Fund to continue to hold a position  until delivery
or expiration  regardless of changes in its value. As a result,  a Fund's access
to other  assets  held to cover its options or futures  positions  could also be
impaired.


                                       13
OTC OPTIONS

     Bond and Government  Funds may engage in OTC options  transactions.  Unlike
exchange-traded  options,  which are standardized with respect to the underlying
instrument,  expiration  date,  contract  size,  and strike price,  the terms of
over-the-counter  options  (options  not  traded  on  exchanges)  generally  are
established  through  negotiation  with the other party to the option  contract.
While this type of  arrangement  allows a Fund greater  flexibility to tailor an
option to its needs,  OTC options  generally  involve  greater  credit risk than
exchange-traded  options,  which are guaranteed by the clearing  organization of
the exchanges where they are traded.

OPTIONS AND FUTURES RELATING TO FOREIGN CURRENCIES

     Bond and  Government  Funds may engage in options and futures  transactions
relating  to foreign  currencies.  Currency  futures  contracts  are  similar to
forward currency  exchange  contracts,  except that they are traded on exchanges
(and have margin  requirements)  and are  standardized  as to contract  size and
delivery date. Most currency  futures  contracts call for payment or delivery in
U.S.  dollars.  The underlying  instrument of a currency option may be a foreign
currency,  which  generally  is  purchased  or  delivered  in exchange  for U.S.
dollars, or may be a futures contract.  The purchaser of a currency call obtains
the right to purchase the underlying  currency,  and the purchaser of a currency
put obtains the right to sell the underlying currency.

     The uses and risks of  currency  options and futures are similar to options
and futures  relating to securities or indexes,  as discussed  above. A Fund may
purchase and sell currency  futures and may purchase and write currency  options
to increase or decrease its exposure to different foreign currencies. A Fund may
also purchase and write currency  options in conjunction with each other or with
currency futures or forward  contracts.  Currency futures and options values can
be expected to correlate with exchange rates,  but may not reflect other factors
that affect the value of a Fund's  investments.  A currency hedge,  for example,
should  protect a  yen-denominated  security from a decline in the yen, but will
not protect a Fund against a price decline  resulting from  deterioration in the
issuer's  creditworthiness.  Because  the value of a Fund's  foreign-denominated
investments  changes in response to many factors other than exchange  rates,  it
may not be possible  to match the amount of currency  options and futures to the
value of a Fund's investments exactly over time.

ASSET COVERAGE FOR FUTURES AND OPTIONS POSITIONS

     Each Fund will comply with  guidelines  established  by the  Securities and
Exchange  Commission with respect to coverage of options and futures  strategies
by mutual funds,  and if the  guidelines  so require will set aside  appropriate
liquid  assets in a  segregated  custodial  account  in the  amount  prescribed.
Securities  held in a  segregated  account  cannot be sold while the  futures or
option  strategy is  outstanding,  unless they are replaced with other  suitable
assets.  As a  result,  there  is a  possibility  that  segregation  of a  large
percentage  of a Fund's  assets could impede  portfolio  management  or a Fund's
ability to meet redemption requests or other current obligations.


                             INVESTMENT RESTRICTIONS

     As indicated in the  Prospectus,  each Fund is subject to certain  policies
and  restrictions  which  are  "fundamental"  and  may  not be  changed  without
shareholder  approval.  Shareholder  approval  consists  of the  approval of the
lesser of (i) more than 50% of the outstanding  voting  securities of a Fund, or
(ii) 67% or more of the voting securities present at a meeting if the holders of
more than 50% of the  outstanding  voting  securities of the Fund are present or
represented  by proxy.  Limitations  1 through  8 below are  deemed  fundamental
limitations.  The  remaining  limitations  set forth  below  serve as  operating
policies  of each  Fund and may be  changed  by the Board of  Directors  without
shareholder approval.

                                       14

     Each Fund may not:

     1. Purchase the  securities of any issuer if such purchase  would cause the
Fund to fail to meet the  requirements  of a  "diversified  company"  as defined
under the Investment Company Act of 1940, as amended (the "1940 Act").

     2.  Purchase  the   securities  of  any  issuer  (other  than   "Government
securities" as defined under the 1940 Act) if, as a result, more than 25% of the
value  of the  Fund's  total  assets  would be  invested  in the  securities  of
companies whose principal business activities are in the same industry.

     For purposes of applying this restriction, a Fund will not
purchase securities, as defined above, such that 25% or more of the value of the
Fund's total assets are invested in the securities of companies  whose principal
business activities are in the same industry.

     3. Issue any senior securities,  except as permitted by the 1940 Act or the
Rules and Regulations of the Securities and Exchange Commission.

     4. Borrow  money,  except from banks for  temporary or  emergency  purposes
provided that such  borrowings may not exceed 33-1/3% of the value of the Fund's
net assets (including the amount  borrowed).  Any borrowings that come to exceed
this  amount  will be reduced  within  three  days (not  including  Sundays  and
holidays) to the extent  necessary to comply with the 33-1/3%  limitation.  This
limitation  shall not  prohibit  the Fund from  engaging  in reverse  repurchase
agreements,  making  deposits  of assets to margin  or  guarantee  positions  in
futures,   options,  swaps  or  forward  contracts,  or  segregating  assets  in
connection with such agreements or contracts.

     To the extent a Fund engages in reverse repurchase agreements, because such
transactions  are  considered  borrowing,   reverse  repurchase  agreements  are
included in the 33-1/3% limitation.

     5. Act as an  underwriter  of  securities of other  issuers,  except to the
extent that in connection with the disposition of portfolio  securities the Fund
may be deemed to be an underwriter under applicable laws.

     6. Purchase or sell real estate unless acquired as a result of ownership of
securities or other  instruments.  This  restriction  shall not prevent the Fund
from  investing  in  securities  or other  instruments  backed by real estate or
securities of companies engaged in the real estate business.

     7.  Purchase  or sell  commodities  other than  foreign  currencies  unless
acquired as a result of  ownership  of  securities.  This  limitation  shall not
prevent the Fund from purchasing or selling options,  futures, swaps and forward
contracts  or from  investing  in  securities  or other  instruments  backed  by
commodities.

     For purposes of applying this restriction, "commodities" shall be deemed to
include commodity contracts.

     8. Make loans to other persons except to the extent not  inconsistent  with
the 1940  Act or the  Rules  and  Regulations  of the  Securities  and  Exchange
Commission.  This  limitation  does not apply to purchases of commercial  paper,
debt  securities  or  repurchase  agreements,  or to the  lending  of  portfolio
securities.

     9.  Purchase  securities  on margin,  except  that the Fund may obtain such
short-term  credits as may be necessary  for the clearance of purchases or sales
of securities and provided that margin payments in connection with  transactions
in  options,  futures,  swaps  and  forward  contracts  shall  not be  deemed to
constitute purchasing securities on margin.

     10.  Sell  securities  short,  unless  it owns or has the  right to  obtain
securities  equivalent  in kind and amount to the  securities  sold  short,  and
provided that  transactions in options,  swaps and forward futures contracts are
not deemed to constitute selling securities short.

     For purposes of applying this restriction,  a Fund will not sell securities
short  except to the extent that it  contemporaneously  owns or has the right to
obtain at no added cost securities identical to those sold short.

                                       15
<PAGE>

     11.   Except  as  part  of  a  merger,   consolidation,   acquisition,   or
reorganization,  invest  more than 5% of the  value of its  total  assets in the
securities  of any one  investment  company or more than 10% of the value of its
total assets,  in the  aggregate,  in the  securities of two or more  investment
companies, or acquire more than 3% of the total outstanding voting securities of
any one investment company.

     12.  Mortgage,  pledge or  hypothecate  its  assets  except  to the  extent
necessary to secure  permitted  borrowings.  This  limitation  does not apply to
reverse  repurchase  agreements or in the case of assets  deposited to margin or
guarantee positions in futures, options, swaps or forward contracts or placed in
a segregated account in connection with such contracts.

     13.  Participate  on a joint or a joint and several basis in any securities
trading account.

     14. Invest more than 15% of its net assets in illiquid investments.

     15. Invest directly in interests (including  partnership interests) in oil,
gas or other mineral  exploration or development leases or programs,  except the
Fund may purchase or sell securities issued by corporations engaging in oil, gas
or other mineral exploration or development business.

     Any of a Fund's investment  policies set forth under "Investment  Objective
and  Policies"  in the  Prospectus,  or any  restriction  set forth  above under
"Investment  Restrictions"  which involves a maximum percentage of securities or
assets (other than  Restriction 4) shall not be considered to be violated unless
an  excess  over the  percentage  occurs  immediately  after an  acquisition  of
securities  or  utilization  of assets and results  there from.  With respect to
Restriction  14, each Fund is under a  continuing  obligation  to ensure that it
does not violate the maximum  percentage either by acquisition or by virtue of a
decrease in the value of a Fund's liquid assets.

PORTFOLIO TURNOVER
   
     The  portfolio  turnover  rate is  calculated  by  dividing  the  lesser of
purchases or sales of portfolio securities for the particular fiscal year by the
monthly  average of the value of portfolio  securities  owned by the Fund during
the same fiscal year. "Portfolio securities" for purposes of this calculation do
not include securities with a maturity date of less than twelve (12) months from
the date of investment. A 100% portfolio turnover rate would occur, for example,
if the lesser of the value of purchases or sales of portfolio  securities  for a
particular  year  were  equal to the  average  monthly  value  of the  portfolio
securities  owned during such year. Each Fund's  historical  portfolio  turnover
rates  are set  forth in the  Prospectus  section  "Financial  Highlights".  The
increases in the portfolio  turnover rates for Bond Fund and Government Fund for
the last fiscal year were due to  increased  usage of mortgage  dollar rolls and
new  issue   corporates.   Both  of  these   strategies   provided  more  profit
opportunities  than  normal  last year.  Dollar  rolls  become  attractive  when
mortgage  origination and  refinancing  activity rises (as it did last year with
the drop in interest  rates).  Thus, IAI was able to roll mortgages almost every
month.  Corporate  bond new issue  volume was large  enough to set a record last
year. Thus, IAI was able to buy the new issue,  capture the excess return,  then
sell into the  secondary  market.  Turnover  was high because if more issues are
purchased, more concessions can be captured.
    

                             INVESTMENT PERFORMANCE

     Advertisements  and  other  sales  literature  for each  Fund may  refer to
monthly,  quarterly,  yearly,  cumulative and average annual total return.  Each
such  calculation  assumes all  dividends  and capital  gain  distributions  are
reinvested at net asset value on the appropriate reinvestment dates as described
in the Prospectus,  and includes all recurring fees, such as investment advisory
and management fees,  charged as expenses to all shareholder  accounts.  Each of
monthly,  quarterly  and yearly  total return are computed in the same manner as
cumulative total return, as set forth below.

                                       16
<PAGE>



     Cumulative  total  return is  computed by finding  the  cumulative  rate of
return over the period  indicated  in the  advertisement  that would  equate the
initial  amount  invested  to the  ending  redeemable  value,  according  to the
following formula:

                           CTR = (ERV-P) 100
                                  -----
                                    P

         Where:            CTR      =       Cumulative total return;
                           ERV      =       ending redeemable value at the end
                                            of the period of a hypothetical
                                            $1,000 payment made at the 
                                            beginning of such period; and
                           P        =       initial payment of $1,000

     Average  annual  total  return is computed  by finding  the average  annual
compounded rates of return over the periods indicated in the advertisement  that
would  equate  the  initial  amount  invested  to the ending  redeemable  value,
according to the following formula:


                           P(1+T)n = ERV

         Where:            P        =       a hypothetical initial payment of
                                            $1,000;
                           T        =       average annual total return;
                           n        =       number of years; and
                           ERV      =       ending redeemable value at the end
                                            of the period of a hypothetical
                                            $1,000 payment made at the 
                                            beginning of such period.

     The Fund may quote yield figures from time to time. The "yield" is computed
by dividing the net  investment  income per share earned  during a 30-day period
(using the average  number of shares  entitled to receive  dividends) by the net
asset value per share on the last day of the period.  The yield formula provides
for semiannual  compounding  which assumes that net investment  income is earned
and  reinvested  at a constant  rate and  annualized  at the end of a  six-month
period.  A  "tax-equivalent  yield" is computed  by dividing  the portion of the
yield that is  tax-exempt  by one minus a stated  income tax rate and adding the
product to that portion, if any, of the yield that is not tax-exempt.

                  The yield formula is as follows:

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

                  Where:   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.
                           d = the net asset value of the Fund.

     In advertising and sales literature,  each Fund may compare its performance
with that of other  mutual  funds,  indexes or averages of other  mutual  funds,
indexes of related financial assets or data, and other competing  investment and
deposit  products  available from or through other financial  institutions.  The
composition of these indexes,  averages or products differs from that of a Fund.
The  comparison  of a Fund to an  alternative  investment  should  be made  with
consideration of differences in features and expected performance.

         The  indexes  and  averages  noted  below  will be  obtained  from  the
indicated sources or reporting services, which the Fund believes to be generally
accurate. Each Fund may also note its mention in newspapers, magazines, or other
media from time to time.  However,  each Fund assumes no responsibility  for the
accuracy of such data.

     For example,  (1) a Fund's  performance or P/E ratio may be compared to any
one or a  combination  of the  following:  (i) other  groups  of  mutual  funds,
including the IAI Funds,  tracked by: (A) Lipper  Analytical  Services,  Inc., a
widely  used  independent  research  firm which  ranks  mutual  funds by overall
performance,  investment objectives, and assets; (B) Morningstar,  Inc., another
widely used  independent  research firm which rates mutual  funds;  or (C) other
financial or business  publications,  which may include, but are not limited to,
Business  Week,  Money  Magazine,  Forbes and Barron's,  which  provide  similar
information;  (ii) the Salomon Brothers Broad Investment Grade Index;  (iii) the
Shearson  Lehman  Brothers   Government/Corporate   Bond  Index;  and  (iv)  the
performance  of U.S.  government  and  corporate  bonds,  notes and bills.  (The
purpose  of  these  comparisons  would be to  illustrate  historical  trends  in
different market sectors so as to allow potential investors to compare different
investment  strategies.);  (2) the Consumer  Price Index (measure for inflation)
may be used to assess the real rate of return from an investment in a Fund;  (3)
other U.S. government  statistics such as GNP, and net import and export figures
derived from  governmental  publications,  e.g., The Survey of Current Business,

                                       18
<PAGE>

may be  used  to  illustrate  investment  attributes  of a Fund  or the  general
economic  business,  investment,  or  financial  environment  in  which  a  Fund
operates;  (4) the effect of  tax-deferred  compounding  on a Fund's  investment
returns,  or on returns in general,  may be illustrated by graphs,  charts, etc.
where such graphs or charts would compare, at various points in time, the return
from an  investment  in a Fund (or returns in general) on a  tax-deferred  basis
(assuming  reinvestment  of capital gains and dividends and assuming one or more
tax rates) with the return on a taxable basis;  and (5) the instruments in which
a Fund  invests  may be  compared  to  relevant  indices  or surveys in order to
evaluate a Fund's  historical  performance  or current or  potential  value with
respect to the particular instruments.

MANAGEMENT AGREEMENT

     Effective April 1, 1996,  pursuant to a Management  Agreement  between each
Fund and IAI,  IAI has  agreed to  provide  each Fund  with  investment  advice,
statistical  and  research  facilities,  and  certain  equipment  and  services,
including,  but not limited to,  office space and necessary  office  facilities,
equipment,  and the services of required personnel and, in connection therewith,
IAI has the sole  authority and  responsibility  to make and execute  investment
decisions  for each Fund within the framework of a Fund's  investment  policies,
subject to review by the  directors of a Fund.  In  addition,  IAI has agreed to
provide or arrange  for the  provision  of all  required  administrative,  stock
transfer, redemption, dividend disbursing,  accounting, and shareholder services
including,  without limitation,  the following:  (1) the maintenance of a Fund's
accounts,  books and records;  (2) the calculations of the daily net asset value
in  accordance  with a Fund's  current  Prospectus  and  Statement of Additional
Information;  (3) daily and periodic reports;  (4) all information  necessary to
complete tax returns,  questionnaires and other reports requested by a Fund; (5)
the  maintenance  of stock  registry  records;  (6) the  processing of requested
account  registration  changes,   stock  certificate  issuances  and  redemption
requests; and (7) the administration of payments and dividends and distributions
declared by a Fund; (8) answering shareholder  questions,  (9) providing reports
and other information and (10) other services  designed to maintain  shareholder
accounts. IAI may also pay qualifying broker-dealers, financial institutions and
other entities that provide such services.  In return for these  services,  each
Fund has agreed to pay IAI an annual fee as a percentage  of the Fund's  average
daily net assets as set forth below:

                   For the first $100 million                  1.10%

                   Above $250 million                          1.00%
</TABLE>


     Under the Management Agreement,  except for brokerage commissions and other
expenditures in connection  with the purchase and sale of portfolio  securities,
interest  expense,  and,  subject to the specific  approval of a majority of the
disinterested  directors of a Fund, taxes and  extraordinary  expenses,  IAI has
agreed to pay all of a Fund's other costs and expenses,  including, for example,
costs  incurred  in the  purchase  and sale of  assets,  taxes,  charges  of the
custodian of a Fund's  assets,  costs of reports and proxy material sent to Fund
shareholders,  fees paid for independent accounting and legal services, costs of
printing  Prospectuses  for Fund  shareholders  and registering a Fund's shares,
postage, insurance premiums, and costs of attending investment conferences.  The
Management  Agreement further provides that IAI will either reimburse a Fund for
the fees and expenses it pays to directors who are not "interested persons" of a
Fund or reduce its fee by an equivalent  amount.  IAI is not liable for any loss
suffered  by a Fund  in  the  absence  of  willful  misfeasance,  bad  faith  or
negligence in the performance of its duties and obligations.

   
     As of November  30,  1997,  Bond Fund had  $68,620,361  in net assets,  and
Government  Fund had  $18,912,867  in net  assets.  For the  fiscal  year  ended
November 30, 1997, Bond Fund and Government Fund paid IAI $812,134 and $261,333,
respectively,  pursuant to the Management  Agreement.  For the fiscal year ended
November 30, 1996, Bond Fund and Government Fund paid IAI $570,078 and $272,519,
respectively, pursuant to the Management Agreement.
    

PRIOR AGREEMENTS
   
     Effective March 31, 1996, the Investment  Advisory  Agreement  between each
Fund and IAI was terminated and replaced by the Management  Agreement  described
above.

     Under the Investment Advisory  Agreements,  each Fund had agreed to pay IAI
an advisory fee at an annual rate of .55% of the Fund's average net assets.  For
the fiscal  years ended  November  30, 1995 and 1996  (i.e.,  December  31, 1995
through   March  31,  1996),   Bond  Fund  paid  IAI  $441,516,   and  $141,722,
respectively,  under the Advisory Agreement. For those same periods,  Government
Fund paid IAI $238,633 and $84,410 under the Advisory Agreement.

DURATION OF AGREEMENTS

     Each Management Agreement will terminate  automatically in the event of its
assignment.  In  addition,  each  Agreement  is  terminable  at any time without
penalty by the Board of Directors of a Fund or by vote of a majority of a Fund's
outstanding  voting  securities on not more than 60 days' written notice to IAI,
and by IAI on 60 days' notice to a Fund. Each Agreement shall continue in effect
from year to year only so long as such  continuance is specifically  approved at
least  annually  by either  the Board of  Directors  of the Fund or by vote of a
majority of the  outstanding  voting  securities,  provided that in either event
such continuance is also approved by the vote of a majority of directors who are
not parties to the  Agreement  or  interested  persons of such  parties  cast in
person at a meeting called for the purpose of voting on such approval.

                                CUSTODIAL SERVICE
   
     The custodian for the Funds is Norwest Bank Minnesota, N.A. Norwest Center,
Sixth  and  Marquette,  Minneapolis,  MN  55479.  Norwest  has  entered  into an
agreement with Morgan Stanley Trust Company, 1 Pierrepont Plaza,  Brooklyn,  New
York ("Morgan  Stanley") which enables Bond and Government  Funds to utilize the
subcustodian  and  depository  network  of  Morgan  Stanley.   
    

               PORTFOLIO TRANSACTIONS AND ALLOCATION OF BROKERAGE

     Most of each  Fund's  portfolio  transactions  are  effected  with  dealers
without the payment of brokerage  commissions  but at a net price which  usually
includes a spread or markup. In effecting such portfolio  transactions on behalf
of a Fund,  IAI seeks the most  favorable  net  price  consistent  with the best
execution.  However,  frequently  IAI  selects a dealer  to effect a  particular
transaction  without  contacting  all  dealers  who might be able to effect such
transaction  because of the  volatility of the bond market and the desire of IAI
to accept a  particular  price for a security  because the price  offered by the
dealer meets its guidelines for profit, yield or both.

     So long as IAI believes that it is obtaining the best net price  (including
the spread or markup) consistent with the best execution, as described above, it
gives  consideration  in placing  portfolio  transactions to dealers  furnishing
research,  statistical information, or other services to IAI. This allows IAI to
supplement its own investment  research activities and enables IAI to obtain the
views and  information  of  individuals  and research  staffs of many  different
securities firms prior to making investment  decisions for a Fund. To the extent
portfolio  transactions are effected with dealers who furnish research  services
to it, IAI  receives a benefit  which is not  capable  of  evaluation  in dollar
amounts.

   
     Consistent  with the  Rules  of  Conduct  of the  National  Association  of
Securities Dealers,  Inc. and subject to the policies set forth in the preceding
paragraphs  and such other  policies as the Board of  Directors  of the Fund may
determine,  IAI may consider  sales of shares of a Fund, or any IAI Mutual Fund,
as a factor in the selection of  broker-dealers to execute the Fund's securities
transactions.
    

     IAI believes that most research  services  obtained by it generally benefit
one or more of the  investment  companies  or other  accounts  which it manages.
Research  services  obtained from  transactions in fixed income securities would
primarily  benefit the managed funds investing such fixed income  securities and
managed accounts investing in fixed income securities.

                    NET ASSET VALUE AND PUBLIC OFFERING PRICE

     The portfolio securities in which each Fund invests fluctuate in value, and
hence, for each Fund, the net asset value per share also fluctuates.

   
     The net asset value per share of a Fund is determined  once daily as of the
close of trading on the New York Stock  Exchange on each  business  day on which
the New York  Stock  Exchange  is open for  trading,  and may be  determined  on
additional  days  as  required  by the  Rules  of the  Securities  and  Exchange
Commission.  The New York Stock Exchange is closed,  and the net asset value per
share of a Fund is not  determined,  on the  following  national  holidays:  New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,  Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
    

   
     On November 30,  1997,  the net asset value and public  offering  price per
share of each Fund was calculated as follows:

BOND FUND

NAV =     Net Assets ($68,620,361)            =     $9.49
          -----------------------------
          Shares Outstanding (7,229,457)

GOVERNMENT FUND

NAV =     Net Assets ($18,912,867)             =     $9.80
          ------------------------------
          Shares Outstanding (1,929,269)

    


   
     Each Fund has  authorized  one or more  brokers  to  accept  on its  behalf
purchase  and  redemption  orders and such brokers are  authorized  to designate
other  intermediaries  to  accept  purchase  and  redemption  orders on a Fund's
behalf.  Each Fund will be deemed to have  received  a  purchase  or  redemption
norder  when an  authorized  broker or, if  applicable,  a  broker's  authorized
designee,  accepts the order.  In such  circumstances,  customer  orders will be
priced at a Fund's NAV next  computed  after they are accepted by an  authorized
broker or the broker's authorized designee.
    

                       PURCHASES AND REDEMPTIONS IN KIND
   
     In extraordinary circumstances, Fund shares may be purchased for cash or in
exchange for securities which are permissible  investments of a Fund, subject to
IAI's  discretion and its  determination  that the  securities  are  acceptable.
Securities  accepted  in  exchange  will  be  valued  on  the  basis  of  market
quotations,  or if market  quotations  are not  available,  by a method that IAI
believes  accurately  reflects fair value. In addition,  securities  accepted in
exchange  are required to be liquid  securities  that are not  restricted  as to
transfer.  Also in extraordinary  circumstances,  Fund shares may be redeemed in
exchange for readily marketable  securities held by a Fund.  Securities redeemed
in  exchange  will be valued on the  basis of  market  quotations,  or if market
quotations are not available,  by a method that IAI believes accurately reflects
fair value.
    

                                   TAX STATUS

     The tax status of the Funds and the distributions of the Funds in the hands
of  the  shareholders  are  summarized  in  the  Prospectus  under   "Dividends,
Distributions and Tax Status."

     It is not expected  that  distributions  from any of the Funds will qualify
for the dividends received deduction in the case of corporate shareholders since
the  distributions   will  not  be  derived  from  dividends  paid  by  domestic
corporations.

   
     If Fund  shares are sold or  otherwise  disposed of more than one year from
the date of  acquisition,  the difference  between the price paid for the shares
and the sales price  generally will result in long-term  capital gain or loss to
the Fund  shareholder  if, as is usually the case, the Fund shares are a capital
asset in the hands of the Fund  shareholder at that time. For  shareholders  who
are  individuals,  estates,  or  trusts,  the  gain or loss  will be  considered
long-term  (20%  gain) if the  shareholder  has held the shares for more than 18
months and mid-term (28% gain) if the  shareholder  has held the shares for mroe
than one year but not more than 18 months. However, under a special provision in
the Internal Revenue Code of 1986, as amended (the "Code"),  if Fund shares with
respect to which a long-term  capital gain  distribution  has been,  or will be,
made are held for six months or less, any loss on the sale or other  disposition
of  such  shares  will  be  long-term   capital  loss  to  the  extent  of  such
distribution.
    


                                       25

<PAGE>

     Ordinarily,   distributions   and  redemption   proceeds   earned  by  Fund
shareholders are not subject to withholding of federal income tax. However, each
Fund is required to withhold 31% of a shareholder's distributions and redemption
proceeds upon the occurrence of certain events  specified in Section 3406 of the
Code and regulations promulgated thereunder. These events include the failure of
a  Fund  shareholder  to  supply  the  Fund  with  such  shareholder's  taxpayer
identification  number,  and the failure of a Fund  shareholder who is otherwise
exempt from  withholding to properly  document such  shareholder's  status as an
exempt recipient. Additionally,  distributions may be subject to state and local
income taxes,  and the treatment  thereunder  may differ from the federal income
tax consequences discussed above.

     Under the Code,  each Fund will be subject to a  non-deductible  excise tax
equal to 4% of the  excess,  if any,  of the  amount of  investment  income  and
capital gains required to be distributed  pursuant to the Code for each calendar
year over the amount  actually  distributed.  In order to avoid this excise tax,
each Fund  generally  must declare  dividends by the end of each  calendar  year
representing  98% of each Fund's  ordinary income for such calendar year and 98%
of its  capital  gain  net  income  (both  long-term  and  short-term)  for  the
twelve-month  period ending October 31 of the same calendar year. The excise tax
is not imposed,  however,  on  undistributed  income that is already  subject to
corporate  income tax. It is each Fund's policy not to distribute  capital gains
until capital loss carryovers, if any, either are utilized or expire.

     In the case of Bond and  Government  Funds,  income  received  from sources
within foreign  countries may be subject to withholding  and other taxes imposed
by such  countries.  Tax conventions  between  certain  countries and the United
States may reduce or eliminate  such taxes.  It is  impossible  to determine the
effective  rate of foreign tax  applicable  to such income in advance  since the
precise  amount of a Fund's  assets to be invested in various  countries  is not
known. Any amount of taxes paid by Bond or Government Fund to foreign  countries
will reduce the amount of income  available  to such Fund for  distributions  to
shareholders.

     If either Fund invests in zero coupon obligations upon their issuance, such
obligations  will  have  original  issue  discount  in the  hands  of the  Fund.
Generally, the original issue discount equals the difference between the "stated
redemption  price at maturity" of the  obligation and its "issue price" as those
terms are  defined in the Code.  If the Fund  acquires  an already  issued  zero
coupon bond from another  holder,  the bond will have original issue discount in
the Fund's hands,  equal to the difference between the "adjusted issue price" of
the bond at the time the Fund acquires it (that is, the original  issue price of
the bond plus the amount of  original  issue  discount  accrued to date) and its
stated  redemption  price at  maturity.  In each case,  the Fund is  required to
accrue as ordinary  interest  income a portion of such original  issue  discount
even though it receives no cash currently as interest payment on the obligation.
If a Fund invests in U.S. Treasury  inflation-protection  securities, it will be
required to treat as  original  issue  discount  any  increase in the  principal
amount of the securities that occurs during the course of its taxable year. If a
Fund purchases such inflation-protection  securities that are issued in stripped
form  either as  stripped  bonds or  coupons,  it will be  treated  as if it had
purchased a newly issued debt instrument having original issue discount.

   
     Because the Funds are required to distribute substantially all of their net
investment income in order to be taxed as regulated investment  companies,  they
may be required to distribute  an amount  greater than the total cash income the
Fund actually receives. Accordingly, in order to make the required distribution,
the Fund may be required  to borrow or to  liquidate  securities.  
    

     Except for the transactions a Fund has identified as hedging  transactions,
each Fund is required for federal income tax purposes to recognize as income for
each  taxable  year its net  unrealized  gains and losses on futures  contracts,
options,  and forward  currency  contracts as of the end of the year, as well as
those actually  realized  during the year.  Except for  transactions  in futures
contracts, options, or forward currency contracts that are classified as part of
a "mixed  straddle,"  gain or loss  recognized  with respect to such contract or
contracts  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
contract.  In the case of a transaction  classified as a "mixed  straddle",  the
recognition of losses may be deferred to a later taxable year.


                                       26

<PAGE>

     Sales of futures contracts, options, or forward currency contracts that are
intended to hedge against a change in the value of securities or currencies held
by a Fund may affect the holding  period of such  securities or currencies  and,
consequently,  the nature of the gain or loss on such  securities  or currencies
upon disposition.

   
     It is expected  that any net gain  realized from the closing out of futures
contracts,  options,  or forward currency contracts will be considered gain from
the sale of securities  or  currencies  and,  therefore,  qualifying  income for
purposes of the requirement that a regulated  investment company derive at least
90% of its gross income from  dividends,  interest and certain  types of payment
related to its  investment in stock or securities.
     

     Any realized gain or loss on closing out a futures  contracts,  option,  or
forward currency contract such as a forward  commitment for the purchase or sale
of foreign currency will generally  result in a recognized  capital gain or loss
for tax purposes. Code Section 988 may also apply to forward currency contracts.
Under  Section 988,  each foreign  currency  gain or loss is generally  computed
separately  and  treated  as  ordinary  income or loss.  In the case of  overlap
between  Sections 1256 and 988, special  provisions  determine the character and
timing of any income,  gain or loss.  The Funds will attempt to monitor  Section
988 transactions to avoid an adverse tax impact.

     The foregoing is a general and abbreviated summary of the Code and Treasury
regulations in effect as of the date of the Funds' Prospectus and this Statement
of Additional Information as applicable to the Fund and their shareholders.  The
foregoing relates solely to federal income tax law applicable to "U.S. persons,"
i.e., U.S. citizens and residents and U.S. domestic corporations,  partnerships,
trusts and estates.  Shareholders  who are not U.S.  persons are  encouraged  to
consult a tax adviser  regarding the income tax consequences of acquiring shares
of a Fund.

                        LIMITATION OF DIRECTOR LIABILITY

     Under Minnesota law, each Fund's Board of Directors owes certain  fiduciary
duties  to the Fund  and to its  shareholders.  Minnesota  law  provides  that a
director "shall  discharge the duties of the position of director in good faith,
in a manner the director  reasonably  believes to be in the best interest of the
corporation,  and with the care an ordinarily  prudent person in a like position
would exercise under similar circumstances." Fiduciary duties of a director of a
Minnesota  corporation include,  therefore,  both a duty of "loyalty" (to act in
good faith and act in a manner  reasonably  believed to be in the best interests
of the  corporation)  and a duty of "care"  (to act with the care an  ordinarily
prudent person in a like position  would exercise under similar  circumstances).
Minnesota  law  authorizes  corporations  to  eliminate  or limit  the  personal
liability  of a director to the  corporation  or its  shareholders  for monetary
damages  for breach of the  fiduciary  duty of "care."  Minnesota  law does not,
however,  permit a corporation to eliminate or limit the liability of a director
(i) for any breach of the director's duty of "loyalty" to the corporation or its
shareholders,  (ii)  for acts or  omissions  not in good  faith or that  involve
intentional  misconduct or a knowing  violation of law, (iii) for  authorizing a
dividend,  stock repurchase or redemption or other  distribution in violation of
Minnesota  law or for violation of certain  provisions  of Minnesota  securities
laws, or (iv) for any  transaction  from which the director  derived an improper
personal benefit. The Articles of Incorporation of IAI Investment Funds I, Inc.,
and IAI Investment Fund VI, Inc. limit the liability of directors to the fullest
extent permitted by Minnesota statutes, except to the extent that such liability
cannot be limited as provided in the  Investment  Company Act of 1940 (which Act
prohibits  any  provisions  which  purport to limit the  liability  of directors
arising from such directors' willful  misfeasance,  bad faith, gross negligence,
or  reckless  disregard  of the duties  involved in the conduct of their role as
directors).

                                       27
<PAGE>

     Minnesota  law  does  not  eliminate  the  duty of  "care"  imposed  upon a
director.  It only authorizes a corporation to eliminate  monetary liability for
violations of that duty. Minnesota law, further,  does not permit elimination or
limitation  of liability of "officers"  of the  corporation  for breach of their
duties as officers  (including  the liability of directors who serve as officers
for  breach  of their  duties  as  officers.)  Minnesota  law  does  not  permit
elimination  or  limitation of the  availability  of equitable  relief,  such as
injunctive  or  rescissionary  relief.  Further,  Minnesota  law does not permit
elimination or limitation of a director's  liability under the Securities Act of
1933 or the Securities  Exchange Act of 1934, and it is uncertain whether and to
what extent the elimination of monetary  liability would extend to violations of
duties imposed on directors by the Investment  Company Act of 1940 and the rules
and regulations adopted under such Act.

                                   APPENDIX A

                           RATINGS OF DEBT SECURITIES

RATINGS BY MOODY'S

CORPORATE BONDS

     Aaa.  Bonds 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 most  unlikely  to impair the
fundamentally strong position of such issues.

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

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

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

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

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

                                      A-1
<PAGE>


     Conditional  Ratings. The designation "Con." followed by a rating indicates
bonds for which the  security  depends  upon the  completion  of some act or the
fulfillment  of some  condition.  These are bonds  secured  by (a)  earnings  of
projects under  construction,  (b) earnings or projects  unseasoned in operating
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:  Moody's  applies  numerical  modifiers  1, 2,  and 3 in the Aa and A
classifications  of its corporate bond rating  system.  The modifier 1 indicates
that the security  ranks in the higher end of its generic rating  category;  the
modifier 2 indicates a mid-range ranking;  and the modifier 3 indicates that the
issue ranks in the lower end of its generic  rating  category.  With  respect to
municipal  securities,  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

     Moody's  employs  the  following  three  designations,  all  judged  to  be
investment grade, to indicate the relative repayment capacity of rated issuers:

     Prime  - 1  Superior  ability  for  repayment  of  senior  short-term  debt
obligations

     Prime  -  2  Strong  ability  for  repayment  of  senior   short-term  debt
obligations

     Prime - 3  Acceptable  ability  for  repayment  of senior  short-term  debt
obligations

     If an issuer  represents to Moody's that its Commercial  Paper  obligations
are supported by the credit of another entity or entities, Moody's, in assigning
ratings to such  issuers,  evaluates  the  financial  strength of the  indicated
affiliated   corporations,   commercial  banks,  insurance  companies,   foreign
governments,  or other  entities,  but only as one  factor in the  total  rating
assessment.


RATINGS BY S&P

CORPORATE BONDS

     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 higher 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.

                                      A-2
<PAGE>

     BB. Debt rated BB has less  near-term  vulnerability  to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,  financial,  or  economic  conditions  which  could  lead  to
inadequate capacity to meet timely interest and principal payments.

     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-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.

     CC. Debt rated CC is typically  applied to debt subordinated to senior debt
which is assigned an actual or implied CCC debt rating.

     C. The rating C typically applied to debt subordinated to senior debt which
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.

     C1. The rating C1 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 will be used upon
the filing of a bankruptcy petition if debt service payments are jeopardized.

     In order to provide more detailed indications of credit quality, S&P's bond
letter ratings  described above (except for the AAA category) may be modified by
the  addition  of a plus or a minus sign to show  relative  standing  within the
rating category.

COMMERCIAL PAPER

     A. This highest rating category  indicates the greatest capacity for timely
payment. Issues in this category are further defined with the designations 1, 2,
and 3 to indicate the relative degree to safety.

     A-1. This designation  indicates that the degree of safety regarding timely
payment is either  overwhelming  or very  strong.  Those  issues  determined  to
possess overwhelming safety characteristics are designed A-1+.

     A-2.  Capacity  for timely  payments  on issues  with this  designation  is
satisfactory.  However,  the  relative  degree  of  safety is not as high as for
issues designed A-1.

     A-3. Issues  carrying this  designation  have adequate  capacity for timely
repayment.  They are, however, more vulnerable to the adverse effects of changes
in circumstances than obligations carrying the higher designations.

                        INVESTMENT OBJECTIVE AND POLICIES

     The investment  objective and policies of IAI Institutional  Bond Fund (the
"Fund") are  summarized on the front page of the  Prospectus  and in the text of
the  Prospectus  under  "Investment  Objective and Policies."  Investors  should
understand  that all investments  have a risk factor.  There can be no guarantee
against  loss  resulting  from an  investment  in the Fund,  and there can be no
assurance that the Fund's  investment  policies will be successful,  or that its
investment  objective will be attained.  Certain of the investment  practices of
the Fund are further explained below.

REPURCHASE AGREEMENTS

     The Fund may invest in repurchase  agreements relating to the securities in
which it may invest. A repurchase  agreement involves the purchase of securities
with the condition that, after a stated period of time, the original seller will
buy back the securities at a predetermined  price or yield. The Fund's custodian
will have custody of, and will hold in a segregated account, securities acquired
by the Fund under a repurchase  agreement or other securities as collateral.  In
the case of a security registered on a book entry system, the book entry will be
maintained in the Fund's name or that of its  custodian.  Repurchase  agreements
involve certain risks not associated with direct investments in securities.  For
example, if the seller of the agreement defaults on its obligation to repurchase
the  underlying  securities  at a time  when  the  value of the  securities  has
declined, the Fund may incur a loss upon disposition of such securities.  In the
event that  bankruptcy  proceedings  are commenced with respect to the seller of
the  agreement,  the Fund's  ability to dispose of the collateral to recover its
investment may be restricted or delayed.  While  collateral will at all times be
maintained  in an amount  equal to the  repurchase  price  under  the  agreement
(including  accrued  interest due  thereunder),  to the extent proceeds from the
sale of collateral were less than the repurchase  price, the Fund could suffer a
loss.

REVERSE REPURCHASE AGREEMENTS

     The  Fund  may  invest  in  reverse  repurchase  agreements  as a  form  of
borrowing.  In  a  reverse  repurchase  agreement,  a  fund  sells  a  portfolio
instrument to another party, such as a bank or broker-dealer, in return for cash
and agrees to repurchase the instrument at a particular  price and time. While a
reverse  repurchase  agreement  is  outstanding,   the  Fund  will  comply  with
guidelines  established by the Securities and Exchange Commission  regarding the
segregation of assets.  The Fund will enter into reverse  repurchase  agreements
only  with  parties  whose  creditworthiness  has  been  found  satisfactory  by
Investment  Advisers,  Inc. ("IAI"),  the Fund's investment adviser and manager.
Such  transactions  may increase  fluctuations in the market value of the Fund's
assets  and may be viewed  as a form of  leverage.  The Fund does not  currently
intend  to  invest  more  than  5% of  its  net  assets  in  reverse  repurchase
agreements.

SECURITIES OF FOREIGN ISSUERS

     The Fund may invest in securities of foreign issuers in accordance with its
investment  objectives and policies.  Investing in foreign securities may result
in greater risk than that incurred by investing in domestic securities. There is
generally less publicly  available  information about foreign issuers comparable
to reports and ratings that are published  about companies in the United States.
Also,  foreign  issuers are not subject to uniform  accounting  and auditing and
financial reporting  standards,  practices and requirements  comparable to those
applicable to United States companies. Furthermore, volume and liquidity in most
foreign bond markets is less than in the United  States and at times  volatility
of price can be  greater  than in the United  States.  There is  generally  less
government  supervision  and  regulation  of foreign bond  markets,  brokers and
companies than in the United States.

                                       2
<PAGE>


     With respect to certain  foreign  countries,  there is the  possibility  of
adverse changes in investment or exchange control regulations,  expropriation or
confiscatory  taxation,  limitations  on the removal of funds or other assets of
the Fund,  political or social  instability,  or diplomatic  developments  which
could affect United States investments in those countries.  Moreover, individual
foreign  economies may differ  favorably or unfavorably  from the United States'
economy in such respects as growth of gross national product, rate of inflation,
capital  reinvestment,   resource   self-sufficiency  and  balance  of  payments
position.

     The Fund is not aware at this time of the  existence of any  investment  or
exchange control regulations which might substantially  impair the operations of
the Fund as  described  in the  Prospectus  and  this  Statement  of  Additional
Information.  It should be noted,  however,  that this situation could change at
any time.

     The  dividends  and  interest  payable on  certain  of the  Fund's  foreign
portfolio  securities may be subject to foreign withholding taxes, thus reducing
the net amount of income available for distribution to the Fund's  shareholders.
The expense  ratio of the Fund should not be  materially  affected by the Fund's
investment in foreign securities.

U.S. TREASURY INFLATION PROTECTION SECURITIES

     The  Bond  Fund  may  purchase  securities  issued  by  the  United  States
government, which include U.S. Treasury inflation-protection securities.

     Inflation-protection   securities  are  a  type  of  marketable  book-entry
security issued by the United States Department of Treasury  ("Treasury") with a
nominal  return  linked to the  inflation  rate in prices.  Inflation-protection
securities are auctioned and issued on a quarterly basis on the 15th of January,
April,  July, and October.  They have been issued as 10-year  notes,  with other
maturities  added  thereafter.  The  index  used  to  measure  inflation  is the
non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All
Urban Consumers ("CPI-U").

     The value of the principal is adjusted for inflation,  and every six months
the security will pay interest,  which is an amount equal to a fixed  percentage
of the inflation-adjusted value of the principal. The final payment of principal
of the security will not be less than the original par amount of the security at
issuance.

     The  principal  of the  inflation-protection  security  is  indexed  to the
non-seasonally  adjusted  CPI-U. To calculate the  inflation-adjusted  principal
value for a particular valuation date, the value of the principal at issuance is
multiplied by the index ratio applicable to that valuation date. The index ratio
for any date is the ratio of the  reference  CPI  applicable to such date to the
reference CPI applicable to the original issue date.  Semiannual coupon interest
is determined by multiplying the inflation-adjusted principal amount by one-half
of the stated rate of interest on each interest payment date.

     Inflation-adjusted  principal  or the  original  par amount,  whichever  is
larger,  will be paid  on the  maturity  date  as  specified  in the  applicable
offering announcement.  If at maturity the inflation-adjusted  principal is less
than the original  principal value of the security an additional  amount will be
paid at  maturity  so that the  additional  amount  plus the  inflation-adjusted
principal  equals  the  original  principal  amount.  Some  inflation-protection
securities may be stripped into principal and interest  components.  In the case
of a stripped security,  the holder of the stripped principal would receive this
additional  amount.  The final interest payment,  however,  will be based on the
final inflation-adjusted principal value, not the original par amount.

     The reference CPI for the first day of any calendar  month is the CPI-U for
the third preceding calendar month. (For example, the reference CPI for December
1 is the CPI-U  reported for  September  of the same year,  which is released in
October.)  The  reference  CPI for any other day of the month is calculated by a
linear  interpolation  between the reference CPI  applicable to the first day of
the month and the  reference  CPI  applicable  to the first day of the following
month.

                                       3
<PAGE>

     Any revisions the Bureau of Labor Statistics (or successor agency) makes to
any  CPI-U  number  that  has  been  previously  released  will  not be  used in
calculations of the value of outstanding inflation-protection securities. In the
case that the CPI-U for a  particular  month is not  reported by the last day of
the  following  month,  the Treasury  will announce an index number based on the
last  year-over-year  CPI-U  inflation rate available.  Any  calculations of the
Treasury's payment  obligations on the  inflation-protection  security that need
that  month's  CPI-U  number will be based on the index number that the Treasury
has  announced.  If the CPI-U is based to a different  year,  the Treasury  will
continue to use the CPI-U  series based on the base  reference  period in effect
when the  security  was first  issued  as long as that  series  continues  to be
published.    If   the   CPI-U   is   discontinued   during   the   period   the
inflation-protection security is outstanding, the Treasury will, in consultation
with  the  Bureau  of Labor  Statistics  (or  successor  agency),  determine  an
appropriate substitute index and methodology for linking the discontinued series
with the new price index series. Determinations of the Secretary of the Treasury
in this regard are final.

     Inflation-protection  securities  will be held and transferred in either of
two book-entry systems:  the commercial  book-entry system (TRADES) and TREASURY
DIRECT.  The securities will be maintained and transferred at their original par
amount, i.e., not at their  inflation-adjusted  value. STRIPS components will be
maintained  and  transferred  in TRADES at their value based on the original par
amount of the fully constituted security.

LENDING PORTFOLIO SECURITIES

     In order  to  generate  additional  income,  the  Fund  may lend  portfolio
securities to broker-dealers,  banks or other financial borrowers of securities.
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,  the Fund will only  enter  into loan  arrangements  with
broker-dealers,  banks  or  other  institutions  which  IAI has  determined  are
creditworthy under guidelines established by the Fund's Board of Directors.  The
Fund may also  experience  a loss if,  upon the  failure of a borrower to return
loaned  securities,  the  collateral is not  sufficient in value or liquidity to
cover the value of such loaned securities  (including accrued interest thereon).
However,  the Fund will receive  collateral  in the form of cash,  United States
Government securities,  certificates of deposit or other high-grade,  short-term
obligations or  interest-bearing  cash equivalents equal to at least 102% of the
value  of  the  securities  loaned.  The  value  of  the  collateral  and of the
securities  loaned  will be marked to market on a daily  basis.  During the time
portfolio  securities  are on  loan,  the  borrower  pays  the  Fund  an  amount
equivalent to any dividends or interest paid on the  securities and the Fund may
invest the cash collateral and earn  additional  income or may receive an agreed
upon amount of interest income from the borrower.  However, the amounts received
by the Fund may be reduced by finders' fees paid to  broker-dealers  and related
expenses.

ILLIQUID SECURITIES

     The Fund may also invest up to 15% of its net assets in securities that are
considered  illiquid because of the absence of a readily available market or due
to legal or contractual  restrictions.  However,  certain restricted  securities
that are not  registered  for sale to the  general  public that can be resold to
institutional  investors may be considered liquid pursuant to guidelines adopted
by the Board of Directors. In the case of a Rule 144A Security, such security is
deemed to be liquid if:

     (1) IAI reasonably expects to be able to resell the security to a qualified
institutional  buyer, as defined in paragraph  (a)(1) of Rule 144A, who is aware
of  the  Fund's  reliance  upon  Rule  144A  in  selling  the  security  without
registration, as required by paragraph (d)(2) of Rule 144A;

     (2) the  Rule  144A  Security  is not (a) of the same  class as  securities
listed on any  national  securities  exchange or quoted in NASDAQ as  determined
under  paragraph  (d)(3)(i)  of Rule  144A,  or (b) a security  of a  registered
investment company (other than a closed-end investment company); and

                                       4
<PAGE>


     (3) the issuer (a) is a foreign government  eligible to register securities
under  Schedule B of the  Securities  Act of 1933,  (b) is a company  that files
periodic  reports under the Securities  Act of 1934 on Forms 8-K, 10-Q,  10-K or
20-F or provides information under Rule 12g3-2(b) thereunder,  or (c) has agreed
in writing to provide the holder and any prospective  purchaser of the Rule 144A
Security  with  reasonably  current  financial  information  as  required  under
paragraph (d)(4)(i) of Rule 144A.

     Other  securities  are  deemed  to be  liquid  if IAI  determines  that the
security can be disposed of within seven days in the ordinary course of business
at  approximately  the amount at which the Funds have valued the  instrument for
purposes  of   calculating   the  Fund's  net  asset   value.   In  making  this
determination,  IAI will  consider such factors as may be relevant to the Fund's
ability to dispose of the security,  including but not limited to, the following
factors (none of which, standing alone, would necessarily be determinative):

     1. the frequency of trades and quotes for the security;

     2. the number of dealers  willing to purchase or sell the  security and the
number of potential purchasers;

     3. dealer undertakings to make a market in the security; and

     4. the  nature of the  security  and the nature of the  marketplace  trades
(e.g.,  the time  needed to dispose of the  security,  the method of  soliciting
offers and the mechanics of transfer).

     It is  not  possible  to  predict  with  assurance  the  maintenance  of an
institutional trading market for such securities and the liquidity of the Fund's
investments could be impaired if trading declines.

VARIABLE OR FLOATING RATE INSTRUMENTS

     Such  instruments  (including  notes purchased  directly from issuers) bear
variable or floating  interest rates and may carry rights that permit holders to
demand payment of the unpaid  principal  balance plus accrued  interest from the
issuers or certain  financial  intermediaries.  Floating  rate  securities  have
interest rates that change  whenever there is a change in a designated base rate
while variable rate instruments  provide for a specified periodic  adjustment in
the interest  rate.  These formulas are designed to result in a market value for
the instrument that approximates its par value.

DELAYED-DELIVERY TRANSACTIONS

     The Fund may buy and sell securities on a  delayed-delivery  or when-issued
basis. These  transactions  involve a commitment by the Fund to purchase or sell
specific securities at a predetermined price or yield, with payment and delivery
taking  place after the  customary  settlement  period for that type of security
(and more than seven days in the future).  Typically, no interest accrues to the
purchaser  until  the  security  is  delivered.  The Fund may  receive  fees for
entering into delayed-delivery transactions.

     When purchasing  securities on a  delayed-delivery  basis, the Fund assumes
the  rights  and  risks of  ownership,  including  the risk of price  and  yield
fluctuations.  Because the Fund is not required to pay for securities  until the
delivery  date,  these risks are in addition  to the risks  associated  with the
Fund's other investments.  If the Fund remains substantially fully invested at a
time when delayed  delivery  purchases  are  outstanding,  the  delayed-delivery
purchases may result in a form of leverage. When delayed-delivery  purchases are
outstanding,  the Fund will comply with guidelines established by the Securities
and Exchange  Commission  regarding the segregation of assets. When the Fund has
sold a security on a  delayed-delivery  basis,  the Fund does not participate in
further  gains or losses with respect to the  security.  If the other party to a
delayed-delivery  transaction  fails to deliver or pay for the  securities,  the
Fund could miss a favorable price or yield opportunity, or could suffer a loss.

     The Fund  may  renegotiate  delayed-delivery  transactions  after  they are
entered into,  and may sell  underlying  securities  before they are  delivered,
which may result in capital gains or losses.

DOLLAR ROLLS

     In connection  with its ability to purchase  securities on a when-issued or
forward  commitment  basis,  the Fund may enter into "dollar rolls" in which the
Fund sells  securities  for  delivery  in the current  month and  simultaneously
contracts with the same  counterparty to repurchase  similar (same type,  coupon
and maturity) but not identical  securities on a specified future date. The Fund
gives up the right to receive  principal  and  interest  paid on the  securities
sold.  However,  the Fund would benefit to the extent of any difference  between
the price  received  for the  securities  sold and lower  forward  price for the
futures purchase plus any fee income  received.  Unless such benefits exceed the
income and capital  appreciation that would have been realized on the securities
sold as part of the dollar roll,  the use of this  technique  will  diminish the
investment  performance  of the Fund compared with what such  performance  would
have been without the use of dollar rolls.  The Fund will hold and maintain in a
segregated  account until the settlement date cash,  government  securities,  or
liquid  high-grade  debt  securities  in an  amount  equal  to the  value of the
when-issued or forward commitment securities.  The benefits derived from the use
of dollar rolls may depend,  among other  things,  upon IAI's ability to predict
interest  rates  correctly.  There is no  assurance  that  dollar  rolls  can be
successfully  employed.  In addition,  the use of dollar rolls by the Fund while
remaining substantially fully invested increases the amount of the Fund's assets
that are subject to market risk to an amount that is greater than the Fund's net
asset  value,  which could result in  increased  volatility  of the price of the
Fund's shares.

MORTGAGE-BACKED SECURITIES

     The Fund may purchase  mortgage-backed  securities issued by government and
non-government  entities such as banks,  mortgage  lenders,  or other  financial
institutions.  A  mortgage-backed  security may be an  obligation  of the issuer
backed by a mortgage or pool of mortgages or a direct  interest in an underlying
pool of  mortgages.  Some  mortgage-backed  securities,  such as  collateralized
mortgage  obligations or CMOs, make payments of both principal and interest at a
variety  of  intervals;   others  make   semiannual   interest   payments  at  a
predetermined  rate and repay  principal  at  maturity  (like a  typical  bond).
Mortgage-backed  securities are based on different types of mortgages  including
those on  commercial  real  estate or  residential  properties.  Other  types of
mortgage-backed  securities will likely be developed in the future, and the Fund
may  invest  in them if IAI  determines  they are  consistent  with  the  Fund's
investment objective and policies.

     The value of  mortgage-backed  securities  may  change due to shifts in the
market's  perception  of issuers.  In  addition,  regulatory  or tax changes may
adversely  affect  the  mortgage  securities  market as a whole.  Non-government
mortgage-backed  securities  may  offer  higher  yields  than  those  issued  by
government  entities,  but also may be  subject to greater  price  changes  than
government  issues.  Mortgage-backed  securities are subject to prepayment risk.
Prepayment,  which  occurs when  unscheduled  or early  payments are made on the
underlying  mortgages,  may shorten the effective maturities of these securities
and may lower their total returns.

STRIPPED MORTGAGE BACKED SECURITIES

     Such  securities are created when a U.S.  government  agency or a financial
institution separates the interest and principal components of a mortgage-backed
security  and  sells  them  as   individual   securities.   The  holder  of  the
"principal-only"  security  (PO)  receives the  principal  payments  made by the
underlying  mortgage-backed  security,  while the holder of the  "interest-only"
security (IO) receives interest payments from the same underlying security.  The
prices of stripped  mortgage-backed  securities may be particularly  affected by
changes in interest  rates.  As interest  rates fall,  prepayment  rates tend to
increase, which tends to reduce prices of IOs and increase prices of POs. Rising
interest rates can have the opposite effect.

                                       6
<PAGE>


ASSET-BACKED SECURITIES

     Asset-backed  securities  represent  interests  in  pools  of  consumer  or
commercial loans or payment streams (generally  unrelated to mortgage loans) and
often are structured as pass-through securities. Interest and principal payments
alternately depend upon payment of the underlying loans by individuals, although
the   securities  may  be  supported  by  letters  of  credit  or  other  credit
enhancements.  The  value of  asset-backed  securities  may also  depend  on the
creditworthiness of the servicing agent for the loan pool, the originator of the
loans, or the financial institution providing the credit enhancement.

ZERO COUPON BONDS

     Zero coupon bonds do not make interest payments;  instead, they are sold at
a deep  discount  from their face value and are redeemed at face value when they
mature. Because zero coupon bonds do not pay current income, their prices can be
very volatile when interest rates change. In calculating its dividends, the Fund
takes into account as income a portion of the  difference  between a zero coupon
bond's purchase price and its face value.

     A  broker-dealer  creates a derivative  zero by separating the interest and
principal  components  of a U.S.  Treasury  security  and  selling  them  as two
individual  securities.  CATS (Certificates of Accrual on Treasury  Securities),
TIGRs (Treasury  Investment  Growth Receipts),  and TRs (Treasury  Receipts) are
examples of derivative zeros.

     The Federal  Reserve Bank creates  STRIPS  (Separate  Trading of Registered
Interest and Principal of  Securities)  by separating the interest and principal
components of an outstanding  U.S.  Treasury bond and selling them as individual
securities. Bonds issued by the Resolution Funding Corporation (REFCORP) and the
Financing  Corporation  (FICO) can also be separated in this  fashion.  Original
issue  zeroes  are  zero  coupon  securities   originally  issued  by  the  U.S.
government, a government agency, or a corporation in zero coupon form.

LOWER-RATED DEBT SECURITIES

     Issuers of high yield  securities may be highly  leveraged and may not have
available to them more traditional  methods of financing.  Therefore,  the risks
associated  with acquiring the securities of such issuers  generally are greater
than is the case with higher rated securities.  For example,  during an economic
downturn or a sustained  period of rising interest rates,  issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly  leveraged.  During such  periods,  such issuers may not have
sufficient  revenues to meet their interest  payment  obligations.  The issuer's
ability  to service  its debt  obligations  also may be  adversely  affected  by
specific  issuer  developments  or  the  issuer's  inability  to  meet  specific
projected business forecasts or the unavailability of additional financing.  The
risk of loss due to  default  by the  issuer is  significantly  greater  for the
holders of high yield  securities  because such  securities may be unsecured and
may be subordinated to other creditors of the issuer.

     High yield  securities  frequently  have call or redemption  features which
would permit an issuer to repurchase  the security from the Fund. If a call were
exercised by the issuer during a period of declining  interest  rates,  the Fund
likely  would  have to  replace  such  called  security  with a  lower  yielding
security, thus decreasing the net investment income to the Fund and dividends to
shareholders.

     The Fund may have  difficulty  disposing of certain  high yield  securities
because there may be a thin trading  market for such  securities.  The secondary
trading  market  for high yield  securities  is  generally  not as liquid as the
secondary market for higher rated securities. Reduced secondary market liquidity
may have an adverse  impact on market price and the Fund's ability to dispose of
particular  issues  when  necessary  to meet the  Fund's  liquidity  needs or in
response  to  a  specific   economic  event  such  as  a  deterioration  in  the
creditworthiness of the issuer.

                                       7
<PAGE>


     Adverse  publicity  and  investor  perceptions,  which  may not be based on
fundamental  analysis,  also may decrease the value and  liquidity of high yield
securities,  particularly in a thinly traded market. Factors adversely affecting
the market value of high yield  securities  are likely to  adversely  affect the
Fund's net asset value. In addition,  the Fund may incur additional  expenses to
the extent it is required to seek recovery upon a default on a portfolio holding
or participate in the restructuring of the obligation.

SWAP AGREEMENTS

     Swap  agreements can be  individually  negotiated and structured to include
exposure  to a variety of  different  types of  investments  or market  factors.
Depending  on their  structure,  swap  agreements  may  increase or decrease the
Fund's  exposure to long- or short-term  interest rates (in the U.S. or abroad),
foreign  currency values,  mortgage  securities,  corporate  borrowing rates, or
other factors such as security  prices or inflation  rates.  Swap agreements can
take many different  forms and are known by a variety of names.  The Fund is not
limited  to any  particular  form  of swap  agreement  if IAI  determines  it is
consistent with the Fund's investment objectives and policies.

     Swap agreements will tend to shift the Fund's investment  exposure from one
type of  investment  to  another.  For  example,  if the Fund agrees to exchange
payments in dollars for payments in foreign  currency,  the swap agreement would
tend to decrease  the Fund's  exposure to U.S.  interest  rates and increase its
exposure to foreign currency and interest rates. Depending on how they are used,
swap  agreements  may increase or decrease the overall  volatility of the Fund's
investments and its share price.

     The most  significant  factor in the  performance of swap agreements is the
change in the specific interest rate, currency,  or other factors that determine
the amounts of payments due to and from the Fund. If a swap agreement  calls for
payments by the Fund,  the Fund must be prepared to make such payments when due.
In addition,  if the counterparty's  creditworthiness  declined,  the value of a
swap agreement would be likely to decline,  potentially resulting in losses. The
Fund expects to be able to eliminate its exposure under swap  agreements  either
by assignment  or other  disposition,  or by entering  into an  offsetting  swap
agreement with the same party or a similarly  creditworthy  party.  While a swap
agreement is outstanding,  the Fund will comply with  guidelines  established by
the Securities and Exchange Commission regarding the segregation of assets.

INDEXED SECURITIES

     The Fund may purchase  securities whose prices are indexed to the prices of
other  securities,  securities  indexes,  currencies,  precious  metals or other
commodities,  or other financial indicators.  Indexed securities typically,  but
not always,  are debt  securities or deposits  whose value at maturity or coupon
rate  is  determined  by  reference  to  a  specific  instrument  or  statistic.
Gold-indexed  securities,  for example,  typically  provide for a maturity value
that depends on the price of gold,  resulting in a security whose price tends to
rise and fall together with gold prices.  Currency-indexed  securities typically
are short-term to  intermediate-term  debt  securities  whose maturity values or
interest  rates  are  determined  by  reference  to the  values  of one or  more
specified   foreign   currencies,   and  may  offer  higher   yields  than  U.S.
dollar-denominated securities of equivalent issuers. Currency-indexed securities
may be positively  or  negatively  indexed;  that is, their  maturity  value may
increase when the specified  currency value  increases,  resulting in a security
that performs similarly to a foreign-denominated  instrument,  or their maturity
value may decline  when  foreign  currencies  increase,  resulting in a security
whose price  characteristics  are similar to a put on the  underlying  currency.
Currency-indexed  securities may also have prices that depend on the values of a
number of different foreign currencies relative to each other.

     The  performance  of indexed  securities  depends to a great  extent on the
performance  of the security,  currency,  or other  instrument to which they are
indexed,  and may also be  influenced  by interest  rate changes in the U.S. and
abroad.  At the same time,  indexed  securities  are subject to the credit risks
associated  with the  issuer of the  security,  and  their  values  may  decline
substantially if the issuer's creditworthiness  deteriorates.  Recent issuers of
indexed  securities  have  included  banks,   corporations,   and  certain  U.S.
government  agencies.  IAI will use its judgment in determining  whether indexed
securities should be treated as short-term  instruments,  bonds, stocks, or as a
separate asset class for purposes of the Fund's investment  policies,  depending
on the individual  characteristics of the securities.  Indexed securities may be
more volatile than the underlying instruments.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS

     Direct debt  instruments  are  interests  in amounts  owed by a  corporate,
governmental, or other borrower to lenders or lending syndicates (loans and loan
participations),  to  suppliers  of goods or  services  (trade  claims  or other
receivable),  or to other parties.  Direct debt  instruments  are subject to the
Fund's policies regarding the quality of debt securities.

     Purchasers of loans and other forms of direct indebtedness depend primarily
upon the creditworthiness of the borrower for payment of principal and interest.
Direct debt  instruments  may not be rated by any nationally  recognized  rating
service.  If the Fund does not receive scheduled  interest or principal payments
on such  indebtedness,  the  Fund's  share  price and yield  could be  adversely
affected.  Loans that are fully secured offer the Fund more  protection  than an
unsecured loan in the event of  non-payment of scheduled  interest or principal.
However, there is no assurance that the liquidation of collateral from a secured
loan would satisfy the  borrower's  obligation,  or that the  collateral  can be
liquidated.  Indebtedness of borrowers whose  creditworthiness  is poor involves
substantially  greater risks, and may be highly speculative.  Borrowers that are
in bankruptcy or restructuring may never pay off their indebtedness,  or may pay
only a small  fraction of the amount owed.  Direct  indebtedness  of  developing
countries will also involve a risk that the  governmental  entities  responsible
for the repayment of the debt may be unable,  or unwilling,  to pay interest and
repay principal when due.

     Investments in loans through direct assignment of a financial institution's
interests with respect to a loan may involve  additional  risks to the Fund. For
example,  if a loan is  foreclosed,  the Fund  could  become  part  owner of any
collateral,  and would bear the costs and liabilities associated with owning and
disposing of the collateral.  In addition, it is conceivable that under emerging
legal  theories  of  lender  liability,  the  Fund  could  be held  liable  as a
co-lender.  Direct debt instruments may also involve a risk of insolvency of the
lending bank or other  intermediaries.  Direct debt  instruments that are not in
the form of securities may offer less legal  protection to the Fund in the event
of fraud or misrepresentation. In the absence of definitive regulatory guidance,
the Fund relies on IAI's research in an attempt to avoid  situations where fraud
or misrepresentation could adversely affect the Fund.

     A loan is often administered by a bank or other financial  institution that
acts as agent for all holders.  The agent  administers the terms of the loan, as
specified in the loan  agreement.  Unless,  under the terms of the loan or other
indebtedness,  the Fund has direct recourse against the borrower, it may have to
rely on the agent to apply  appropriate  credit remedies against a borrower.  If
assets  held by the agent for the  benefit  of the Fund  were  determined  to be
subject to the claims of the  agent's  general  creditors,  the Fund might incur
certain costs and delays in rendering payment on the loan or loan  participation
and could suffer a loss of principal or interest.

     The Fund  limits the amount of the assets that it invests in any one issuer
or in issuers within the same industry.  For purposes of these limitations,  the
Fund generally will treat the borrower as the "issuer" of  indebtedness  held by
the  Fund.  In the case of loan  participations  where a bank or  other  lending
institution serves as financial  intermediary between the Fund and the borrower,
if the  participation  does not  shift to the  Fund the  direct  debtor/creditor
relationship  with the  borrower,  SEC  interpretations  require  the  Fund,  in
appropriate  circumstances,  to treat  both the  lending  bank or other  lending
institution and the borrower as "issuers" for the purpose of determining whether
the Fund has  invested  more  than 5% of its total  assets  in a single  issuer.
Treating a financial  intermediary as an issuer of indebtedness may restrict the
Fund's  ability  to  invest  in  indebtedness  related  to  a  single  financial
intermediary, or a group of intermediaries engaged in the same industry, even if
the underlying borrowers represent many different companies and industries.

FOREIGN CURRENCY TRANSACTIONS

     The Fund may  hold  foreign  currency  deposits  from  time to time and may
convert dollars and foreign currencies in the foreign exchange markets. Currency
conversion involves dealer spreads and other costs, although commissions usually
are not charged. Currencies may be exchanged on a spot (i.e., cash) basis, or by
entering  into forward  contracts to purchase or sell  foreign  currencies  at a
future date and price.  Forward  contracts  generally are traded in an interbank
market  conducted  directly  between  currency traders (usually large commercial
banks)  and their  customers.  The  parties to a forward  contract  may agree to
offset or terminate the contract  before its maturity,  or may hold the contract
to maturity and complete the contemplated currency exchange.

     The Fund may use currency forward contracts to manage currency risks and to
facilitate   transactions  in  foreign  securities.   The  following  discussion
summarizes  the  principal  currency  management  strategies  involving  forward
contracts that could be used by the Fund.

     In connection with purchases and sales of securities denominated in foreign
currencies, the Fund may enter into currency forward contracts to fix a definite
price for the purchase or sale in advance of the trade's  settlement  date. This
technique  is  sometimes  referred to as a  "settlement  hedge" or  "transaction
hedge."  IAI  expects to enter into  settlement  hedges in the normal  course of
managing the Fund's foreign investments.  The Fund could also enter into forward
contracts  to purchase  or sell a foreign  currency  in  anticipation  of future
purchases or sales of securities  denominated in foreign  currency,  even if the
specific investments have not yet been selected by IAI.

     The Fund may also use forward  contracts to hedge  against a decline in the
value of existing investments  denominated in foreign currency.  For example, if
the Fund owned securities  denominated in pounds sterling, it could enter into a
forward  contract  to sell pounds  sterling in return for U.S.  dollars to hedge
against possible declines in the pound's value. Such a hedge, sometimes referred
to as a  "position  hedge,"  would tend to offset  both  positive  and  negative
currency  fluctuations but would not offset changes in security values caused by
other  factors.  The Fund  could  also hedge the  position  by  selling  another
currency expected to perform similarly to the pound sterling -- for example,  by
entering  into a forward  contract to sell  Deutschemarks  or European  Currency
Units in return for U.S. dollars. This type of hedge, sometimes referred to as a
"proxy hedge," could offer  advantages in terms of cost,  yield,  or efficiency,
but generally would not hedge currency exposure as effectively as a simple hedge
into U.S.  dollars.  Proxy hedges may result in losses if the  currency  used to
hedge does not perform  similarly to the currency in which the hedged securities
are denominated.

     Under certain conditions, SEC guidelines require mutual funds to set
aside  appropriate  liquid  assets in a  segregated  custodial  account to cover
currency  forward  contracts.  As  required  by SEC  guidelines,  the Fund  will
segregate assets to cover currency forward  contracts,  if any, whose purpose is
essentially  speculative.  The Fund will not  segregate  assets to cover forward
contracts  entered  into for  hedging  purposes,  including  settlement  hedges,
position hedges, and proxy hedges.

     Successful use of forward currency  contracts will depend on IAI's skill in
analyzing and predicting  currency values.  Forward  contracts may substantially
change the Fund's investment exposure to changes in currency exchange rates, and
could  result  in  losses  to the  Fund  if  currencies  do not  perform  as IAI
anticipates.  For  example,  if a  currency's  value rose at a time when IAI had
hedged the Fund by selling that currency in exchange for dollars, the Fund would
be unable to participate in the currency's appreciation.  If IAI hedges currency
exposure  through proxy hedges,  the Fund could realize currency losses from the
hedge and the security  position at the same time if the two  currencies  do not
move in tandem.  Similarly,  if IAI increases  the Fund's  exposure to a foreign
currency,  and that  currency's  value  declines,  the Fund will realize a loss.
There is no  assurance  that IAI's use of  forward  currency  contracts  will be
advantageous  to the Fund or that it will  hedge  at an  appropriate  time.  The
policies described in this section are non-fundamental policies of the Fund.

LIMITATIONS ON FUTURES AND OPTIONS TRANSACTIONS

     The  Fund  has  filed a  notice  of  eligibility  for  exclusion  from  the
definition of the term  "commodity  pool  operator"  with the Commodity  Futures
Trading Commission (CFTC) and the National Futures  Association,  which regulate
trading in the futures  markets,  before  engaging in any  purchases or sales of
futures  contracts or options on futures  contracts.  The Fund intends to comply
with Section 4.5 of the  regulations  under the Commodity  Exchange  Act,  which
limits the extent to which the Fund can commit assets to initial margin deposits
and option premiums.

     The above  limitations on the Fund's  investments in futures  contracts and
options,  and the  Fund's  policies  regarding  futures  contracts  and  options
discussed  elsewhere in this Statement of Additional  Information may be changed
as regulatory agencies permit. With respect to positions in commodity futures or
commodity  option  contracts  which do not come within the meaning and intent of
bona fide hedging in the CFTC rules,  the aggregate  initial margin and premiums
required  to  establish  such  positions  will not  exceed  five  percent of the
liquidation value of the Fund's portfolio,  after taking into account unrealized
profits and unrealized  losses on any such  contracts it has entered into;  and,
provided  further,  that in the case of an  option  that is  in-the-money,  such
amount may be excluded in computing such 5 percent.

FUTURES CONTRACTS

     When the Fund  purchases  a  futures  contract,  it agrees  to  purchase  a
specified underlying  instrument at a specified future date. When the Fund sells
a futures contract,  it agrees to sell the underlying  instrument at a specified
future  date.  The price at which the purchase and sale will take place is fixed
when the Fund  enters  into  the  contract.  Some  currently  available  futures
contracts  are based on  specific  securities,  such as U.S.  Treasury  bonds or
notes, and some are based on indexes of securities prices,  such as the Standard
& Poor's 500  Composite  Stock Price Index (S&P 500).  Futures can be held until
their  delivery  dates,  or can be closed out before then if a liquid  secondary
market is available.

     The value of a futures  contract  tends to increase  and decrease in tandem
with the  value of its  underlying  instrument.  Therefore,  purchasing  futures
contracts  will tend to increase  the Fund's  exposure to positive  and negative
price fluctuations in the underlying instrument, much as if it had purchased the
underlying  instrument  directly.  When the Fund  sells a futures  contract,  by
contrast,  the value of its  futures  position  will tend to move in a direction
contrary to the  market.  Selling  futures  contracts,  therefore,  will tend to
offset  both  positive  and  negative  market  price  changes,  much  as if  the
underlying instrument had been sold.

FUTURES MARGIN PAYMENTS

     The purchaser or seller of a futures contract is not required to deliver or
pay for the underlying instrument unless the contract is held until the delivery
date.  However,  both the purchaser and seller are required to deposit  "initial
margin" with a futures  broker,  known as a futures  commission  merchant (FCM),
when the contract is entered into.  Initial margin  deposits are typically equal
to a percentage of the contract's value. If the value of either party's position
declines,  that party will be required  to make  additional  "variation  margin"
payments  to settle the change in value on a daily  basis.  The party that has a
gain may be  entitled to receive  all or a portion of this  amount.  Initial and
variation margin payments do not constitute  purchasing securities on margin for
purposes of the Fund's investment limitations. In the event of the bankruptcy of
an FCM that  holds  margin on behalf of the Fund,  the Fund may be  entitled  to
return of margin  owed to it only in  proportion  to the amount  received by the
FMC's other customers, potentially resulting in losses to the Fund.

PURCHASING PUT AND CALL OPTIONS

     By  purchasing  a put  option,  the Fund  obtains  the  right  (but not the
obligation) to sell the option's underlying  instrument at a fixed strike price.
In return for this right,  the Fund pays the current market price for the option
(known  as the  option  premium).  Options  have  various  types  of  underlying
instruments,  including specific  securities,  indexes of securities prices, and
futures  contracts.  The Fund may  terminate its position in a put option it has
purchased by allowing it to expire or by exercising the option. If the option is
allowed to expire,  the Fund will lose the entire  premium it paid.  If the Fund
exercises the option, it completes the sale of the underlying  instrument at the
strike price.  The Fund may also  terminate a put option  position by closing it
out in the secondary  market at its current price, if a liquid  secondary market
exists.

     The buyer of a typical  put option can expect to realize a gain if security
prices fall substantially.  However,  if the underlying  instrument's price does
not fall enough to offset the cost of  purchasing  the  option,  a put buyer can
expect to suffer a loss (limited to the amount of the premium paid, plus related
transaction costs).

     The  features  of call  options  are  essentially  the same as those of put
options,  except  that the  purchaser  of a call  option  obtains  the  right to
purchase,  rather than sell,  the underlying  instrument at the option's  strike
price.  A call buyer  typically  attempts  to  participate  in  potential  price
increases  of the  underlying  instrument  with risk  limited to the cost of the
option if security prices fall. At the same time, the buyer can expect to suffer
a loss if  security  prices do not rise  sufficiently  to offset the cost of the
option.

WRITING PUT AND CALL OPTIONS

     When the Fund  writes a put  option,  it  takes  the  opposite  side of the
transaction from the option's  purchaser.  In return for receipt of the premium,
the Fund  assumes  the  obligation  to pay the  strike  price  for the  option's
underlying  instrument if the other party to the option  chooses to exercise it.
When writing an option on a futures  contract the Fund would be required to make
margin payments to an FCM as described above for futures contracts. The Fund may
seek to  terminate  its  position in a put option it writes  before  exercise by
closing  out the option in the  secondary  market at its current  price.  If the
secondary  market is not liquid for a put option the Fund has written,  however,
the Fund must  continue to be prepared to pay the strike  price while the option
is  outstanding,  regardless  of price  changes,  and must continue to set aside
assets to cover its  position.  If  security  prices  rise,  a put writer  would
generally expect to profit,  although its gain would be limited to the amount of
the premium it received.

     If security  prices remain the same over time, it is likely that the writer
will also  profit,  because it should be able to close out the option at a lower
price.  If security  prices fall,  the put writer would expect to suffer a loss.
This loss should be less than the loss from purchasing the underlying instrument
directly,  however,  because the premium  received for writing the option should
mitigate the effects of the decline.

     Writing a call option  obligates  the Fund to sell or deliver the  option's
underlying  instrument,  in return for the strike  price,  upon  exercise of the
option.  The  characteristics  of writing  call  options are similar to those of
writing put  options,  except  that  writing  calls  generally  is a  profitable
strategy  if prices  remain  the same or falls.  Through  receipt  of the option
premium,  a call writer  mitigates the effects of a price  decline.  At the same
time,  because  a call  writer  must  be  prepared  to  deliver  the  underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.

<PAGE>


COMBINED POSITIONS

     The Fund may purchase and write options in combination  with each other, or
in combination with futures or forward contracts,  to adjust the risk and return
characteristics  of the overall position.  For example,  the Fund may purchase a
put option and write a call option on the same underlying  instrument,  in order
to  construct  a combined  position  whose risk and return  characteristics  are
similar to selling a futures contract.  Another possible combined position would
involve  writing a call option at one strike price and buying a call option at a
lower price, in order to reduce the risk of the written call option in the event
of a substantial  price increase.  Because  combined options  positions  involve
multiple  trades,  they  result  in  higher  transaction  costs  and may be more
difficult to open and close out.

CORRELATION OF PRICE CHANGES

     Because there are a limited number of types of exchange-traded  options and
futures contracts,  it is likely that the standardized  contracts available will
not match the Fund's current or anticipated  investments  exactly.  The Fund may
invest in options and  futures  contracts  based on  securities  with  different
issuers,  maturities,  or other  characteristics from the securities in which it
typically  invests,  which involves a risk that the options or futures  position
will not track the performance of the Fund's other investments.

     Options  and  futures  prices  can also  diverge  from the  prices of their
underlying  instruments,  even if the  underlying  instruments  match the Fund's
investments  well.  Options and futures  prices are  affected by such factors as
current and anticipated  short-term interest rates, changes in volatility of the
underlying instrument,  and the time remaining until expiration of the contract,
which may not affect  security  prices the same way.  Imperfect  correlation may
also result from differing  levels of demand in the options and futures  markets
and the  securities  markets,  from  structural  differences  in how options and
futures and securities are traded, or from imposition of daily price fluctuation
limits or trading  halts.  The Fund may  purchase  or sell  options  and futures
contracts  with a greater or lesser value than the securities it wishes to hedge
or intends to  purchase in order to attempt to  compensate  for  differences  in
volatility  between the contract and the  securities,  although  this may not be
successful  in all cases.  If price  changes  in the  Fund's  options or futures
positions are poorly  correlated with its other  investments,  the positions may
fail to  produce  anticipated  gains or result in losses  that are not offset by
gains in other investments.

LIQUIDITY OF OPTIONS AND FUTURES CONTRACTS

     There  is no  assurance  a  liquid  secondary  market  will  exist  for any
particular  options or futures contract at any particular time. Options may have
relatively low trading volume and liquidity if their strike prices are not close
to the  underlying  instrument's  current  price.  In  addition,  exchanges  may
establish daily price fluctuation limits for options and futures contracts,  and
may halt  trading if a contract's  price moves upward or downward  more than the
limit in a given day. On volatile trading days when the price  fluctuation limit
is reached or a trading halt is imposed,  it may be  impossible  for the Fund to
enter into new  positions  or close out  existing  positions.  If the  secondary
market for a  contract  is not liquid  because  of price  fluctuation  limits or
otherwise,  it could prevent prompt  liquidation of unfavorable  positions,  and
potentially could require the Fund to continue to hold a position until delivery
or expiration regardless of changes in its value. As a result, the Fund's access
to other  assets  held to cover its options or futures  positions  could also be
impaired.

OTC OPTIONS

     Unlike exchange-traded  options, which are standardized with respect to the
underlying  instrument,  expiration  date,  contract size, and strike price, the
terms of  over-the-counter  options (options not traded on exchanges)  generally
are established through negotiation with the other party to the option contract.
While this type of arrangement allows the Fund greater  flexibility to tailor an
option to its needs,  OTC options  generally  involve  greater  credit risk than
exchange-traded  options,  which are guaranteed by the clearing  organization of
the exchanges where they are traded.

                                       13

OPTIONS AND FUTURES RELATING TO FOREIGN CURRENCIES

     Currency  futures  contracts  are  similar  to  forward  currency  exchange
contracts,   except  that  they  are  traded  on  exchanges   (and  have  margin
requirements)  and are  standardized as to contract size and delivery date. Most
currency  futures  contracts call for payment or delivery in U.S.  dollars.  The
underlying  instrument  of a currency  option may be a foreign  currency,  which
generally is purchased  or delivered in exchange for U.S.  dollars,  or may be a
futures contract. The purchaser of a currency call obtains the right to purchase
the underlying  currency,  and the purchaser of a currency put obtains the right
to sell the underlying currency.

     The uses and risks of  currency  options and futures are similar to options
and futures relating to securities or indexes,  as discussed above. The Fund may
purchase and sell currency  futures and may purchase and write currency  options
to increase or decrease its exposure to different foreign  currencies.  The Fund
may also purchase and write currency  options in conjunction  with each other or
with currency futures or forward contracts.  Currency futures and options values
can be expected to correlate  with  exchange  rates,  but may not reflect  other
factors that affect the value of the Fund's  investments.  A currency hedge, for
example,  should protect a  yen-denominated  security from a decline in the yen,
but  will  not  protect  the  Fund  against  a  price  decline   resulting  from
deterioration in the issuer's creditworthiness.  Because the value of the Fund's
foreign-denominated  investments  changes in response to many factors other than
exchange rates,  it may not be possible to match the amount of currency  options
and futures to the value of the Fund's investments exactly over time.

ASSET COVERAGE FOR FUTURES AND OPTIONS POSITIONS

     The Fund will comply with  guidelines  established  by the  Securities  and
Exchange  Commission with respect to coverage of options and futures  strategies
by mutual funds,  and if the  guidelines  so require will set aside  appropriate
liquid  assets in a  segregated  custodial  account  in the  amount  prescribed.
Securities  held in a  segregated  account  cannot be sold while the  futures or
option  strategy is  outstanding,  unless they are replaced with other  suitable
assets.  As a  result,  there  is a  possibility  that  segregation  of a  large
percentage of the Fund's assets could impede portfolio  management or the Fund's
ability to meet redemption requests or other current obligations.


                             INVESTMENT RESTRICTIONS

     As indicated in the Prospectus, the Fund is subject to certain policies and
restrictions which are "fundamental" and may not be changed without  shareholder
approval.  Shareholder  approval  consists of the  approval of the lesser of (i)
more than 50% of the outstanding  voting  securities of the Fund, or (ii) 67% or
more of the voting  securities  present at a meeting if the holders of more than
50% of the outstanding  voting securities of the Fund are present or represented
by proxy. Limitations 1 through 8 below are deemed fundamental limitations.  The
remaining  limitations  set forth below serve as operating  policies of the Fund
and may be changed by the Board of Directors without shareholder approval.

     The Fund may not:

     1. Purchase the  securities of any issuer if such purchase  would cause the
Fund to fail to meet the  requirements  of a  "diversified  company"  as defined
under the Investment Company Act of 1940, as amended (the "1940 Act").

     As  currently  defined  in the  1940  Act,  "diversified  company"  means a
management company which meets the following  requirements:  at least 75% of the
value of its  total  assets is  represented  by cash and cash  items  (including
receivables),  Government  securities,  securities of other investment companies
and other securities for the purposes of this calculation  limited in respect of
any one  issuer to an amount  not  greater  in value than 5% of the value of the
total assets of such management company and not more than 10% of the outstanding
voting securities of such issuer.

                                       14
<PAGE>

         2.  Purchase  the  securities  of any issuer  (other  than  "Government
securities" as defined under the 1940 Act) if, as a result, more than 25% of the
value  of the  Fund's  total  assets  would be  invested  in the  securities  of
companies whose principal business activities are in the same industry.

     For  purposes  of applying  this  restriction,  the Fund will not  purchase
securities,  as defined above,  such that 25% or more of the value of the Fund's
total  assets are  invested  in the  securities  of  companies  whose  principal
business activities are in the same industry.

     3. Issue any senior securities,  except as permitted by the 1940 Act or the
Rules and Regulations of the Securities and Exchange Commission.

     4. Borrow  money,  except from banks for  temporary or  emergency  purposes
provided that such  borrowings may not exceed 33-1/3% of the value of the Fund's
net assets (including the amount  borrowed).  Any borrowings that come to exceed
this  amount  will be reduced  within  three  days (not  including  Sundays  and
holidays) to the extent  necessary to comply with the 33-1/3%  limitation.  This
limitation  shall not  prohibit  the Fund from  engaging  in reverse  repurchase
agreements,  making  deposits  of assets to margin  or  guarantee  positions  in
futures,   options,  swaps  or  forward  contracts,  or  segregating  assets  in
connection with such agreements or contracts.  To the extent the Fund engages in
reverse  repurchase   agreements,   because  such  transactions  are  considered
borrowing, reverse repurchase agreements are included in the 33 1/3% limitation.

     5. Act as an  underwriter  of  securities of other  issuers,  except to the
extent that in connection with the disposition of portfolio  securities the Fund
may be deemed to be an underwriter under applicable laws.

     6. Purchase or sell real estate unless acquired as a result of ownership of
securities or other  instruments.  This  restriction  shall not prevent the Fund
from  investing  in  securities  or other  instruments  backed by real estate or
securities of companies engaged in the real estate business.

     7. Purchase or sell commodities other than foreign currencies unless
acquired as a result of  ownership  of  securities.  This  limitation  shall not
prevent the Fund from purchasing or selling options,  futures, swaps and forward
contracts  or from  investing  in  securities  or other  instruments  backed  by
commodities.

     For purposes of applying this restriction, "commodities" shall be deemed to
include commodity contracts.

     8. Make loans to other persons except to the extent not  inconsistent  with
the 1940  Act or the  Rules  and  Regulations  of the  Securities  and  Exchange
Commission.  This  limitation  does not apply to purchases of commercial  paper,
debt  securities  or  repurchase  agreements,  or to the  lending  of  portfolio
securities.

     9.  Purchase  securities  on margin,  except  that the Fund may obtain such
short-term  credits as may be necessary  for the clearance of purchases or sales
of securities and provided that margin payments in connection with  transactions
in  options,  futures,  swaps  and  forward  contracts  shall  not be  deemed to
constitute purchasing securities on margin.

     10.  Sell  securities  short,  unless  it owns or has the  right to  obtain
securities  equivalent  in kind and amount to the  securities  sold  short,  and
provided that  transactions in options,  swaps and forward futures contracts are
not deemed to constitute selling securities short.

     For  purposes  of  applying  this  restriction,  the  Fund  will  not  sell
securities short except to the extent that it contemporaneously  owns or has the
right to obtain at no added cost securities identical to those sold short.

reorganization,  invest  more than 5% of the  value of its  total  assets in the
securities  of any one  investment  company or more than 10% of the value of its
total assets,  in the  aggregate,  in the  securities of two or more  investment
companies, or acquire more than 3% of the total outstanding voting securities of
any one investment company.

     12.  Mortgage,  pledge or  hypothecate  its  assets  except  to the  extent
necessary to secure  permitted  borrowings.  This  limitation  does not apply to
reverse  repurchase  agreements or in the case of assets  deposited to margin or
guarantee positions in futures, options, swaps or forward contracts or placed in
a segregated account in connection with such contracts.

gas or other mineral  exploration or development leases or programs,  except the
Fund may purchase or sell securities issued by corporations engaging in oil, gas
or other mineral exploration or development business.

     Any of the Fund's investment policies set forth under "Investment Objective
and  Policies"  in the  Prospectus,  or any  restriction  set forth  above under
"Investment  Restrictions"  which involves a maximum percentage of securities or
assets (other than  Restriction 4) shall not be considered to be violated unless
an  excess  over the  percentage  occurs  immediately  after an  acquisition  of
securities  or  utilization  of assets and results  there from.  With respect to
Restriction 14, the Fund is under a continuing obligation to ensure that it does
not violate  the  maximum  percentage  either by  acquisition  or by virtue of a
decrease in the value of the Fund's liquid securities.

PORTFOLIO TURNOVER
   
     The  portfolio  turnover  rate is  calculated  by  dividing  the  lesser of
purchases or sales of portfolio securities for the particular fiscal year by the
monthly  average of the value of portfolio  securities  owned by the Fund during
the same fiscal year. "Portfolio securities" for purposes of this calculation do
not include securities with a maturity date of less than twelve (12) months from
the date of investment. A 100% portfolio turnover rate would occur, for example,
if the lesser of the value of purchases or sales of portfolio  securities  for a
particular  year  were  equal to the  average  monthly  value  of the  portfolio
securities  owned during such year.  The Fund's  portfolio  turnover rate is set
forth in the Prospectus  section "Financial  Highlights".  The Fund's relatively
high portfolio turnover rate for the last fiscal year was due to increased usage
of mortgage  dollar  rolls and new issue  corporates.  Both of these  strategies
provided more profit  opportunities  than normal last year.  Dollar rolls become
attractive when mortgage  origination and refinancing  activity rises (as it did
last year with the drop in interest rates). Thus, IAI was able to roll mortgages
almost  every month.  Corporate  bond new issue volume was large enough to set a
record  last year.  New issues are often  priced at a  concession  to  secondary
issues  in order  to sell the  deal.  Thus,  IAI was able to buy the new  issue,
capture the excess  return,  then sell into the secondary  market.  Turnover wsa
high because if more issues are purchased, more concessions can be captured.
    

                             INVESTMENT PERFORMANCE

     Advertisements  and  other  sales  literature  for the  Fund  may  refer to
monthly,  quarterly,  yearly,  cumulative and average annual total return.  Each
such  calculation  assumes all  dividends  and capital  gain  distributions  are
reinvested at net asset value on the appropriate reinvestment dates as described
in the Prospectus,  and includes all recurring fees, such as investment advisory
and management fees,  charged as expenses to all shareholder  accounts.  Each of
monthly,  quarterly  and yearly  total return are computed in the same manner as
cumulative total return, as set forth below.

     Cumulative  total  return is  computed by finding  the  cumulative  rate of
return over the period  indicated  in the  advertisement  that would  equate the
initial  amount  invested  to the  ending  redeemable  value,  according  to the
following formula:


                           CTR = (ERV-P) 100
                                  -----
                                    P

         Where:            CTR      =       Cumulative total return;
                           ERV      =       ending redeemable value at the end 
                                            of the period of a hypothetical
                                            $1,000 payment made at the 
                                            beginning of such period; and
                           P        =       initial payment of $1,000

                                       16
<PAGE>

     Average  annual  total  return is computed  by finding  the average  annual
compounded rates of return over the periods indicated in the advertisement  that
would  equate  the  initial  amount  invested  to the ending  redeemable  value,
according to the following formula:

                           P(1+T)n = ERV

         Where:            P        =       a hypothetical initial payment 
                                            of $1,000;
                           T        =       average annual total return;
                           n        =       number of years; and
                           ERV      =       ending redeemable value at the end 
                                            of the period of a hypothetical
                                            $1,000 payment made at the 
                                            beginning of such period.

     The Fund may quote yield figures from time to time. The "yield" is computed
by dividing the net  investment  income per share earned  during a 30-day period
(using the average  number of shares  entitled to receive  dividends) by the net
asset value per share on the last day of the period.  The yield formula provides
for semiannual  compounding  which assumes that net investment  income is earned
and  reinvested  at a constant  rate and  annualized  at the end of a  six-month
period.

     The yield formula is as follows:

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

                  Where:   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.
                           d = the net asset value of the Fund at the end of the
                               period.
   
     The Fund's  yearly  total  returns as of December  31st of each year are as
follows:  1993 - (.84%);  1994 - (4.24%);  1995 - 15.69%;  1996 - 4.62%;  1997 -
8.49%.  The average annual total returns of the Fund for the year ended November
30, 1997 and for the period from the Fund's inception (November 1, 1993) through
November 30, 1997 were 5.97% and 5.28%, respectively.  For the thirty-day period
ended November 30, 1997, the Fund's yield was 6.09%.
    

     In advertising and sales  literature,  the Fund may compare its performance
with that of other  mutual  funds,  indexes or averages of other  mutual  funds,
indexes of related financial assets or data, and other competing  investment and
deposit  products  available from or through other financial  institutions.  The
composition  of these  indexes,  averages or products  differs  from that of the
Fund.  The comparison of the Fund to an  alternative  investment  should be made
with consideration of differences in features and expected performance.

     The indexes and averages  noted below will be obtained  from the  indicated
sources or reporting services, which the Fund believes to be generally accurate.
The Fund may also note its mention in newspapers, magazines, or other media from
time to time.  However,  the Fund assumes no responsibility  for the accuracy of
such data.

     For example, (1) the Fund's performance or P/E ratio may be compared to any
one or a  combination  of the  following:  (i) other  groups  of  mutual  funds,
including the IAI Funds,  tracked by: (A) Lipper  Analytical  Services,  Inc., a
widely  used  independent  research  firm which  ranks  mutual  funds by overall
performance,  investment objectives, and assets; (B) Morningstar,  Inc., another
widely used  independent  research firm which rates mutual  funds;  or (C) other
financial or business  publications,  which may include, but are not limited to,
Business  Week,  Money  Magazine,  Forbes and Barron's,  which  provide  similar
information;  (ii) the Salomon Brothers Broad Investment Grade Index;  (iii) the
Shearson  Lehman  Brothers   Government/Corporate   Bond  Index;  and  (iv)  the
performance  of U.S.  government  and  corporate  bonds,  notes and bills.  (The
purpose  of  these  comparisons  would be to  illustrate  historical  trends  in

                                       17

different market sectors so as to allow potential investors to compare different
investment  strategies.);  (2) the Consumer  Price Index (measure for inflation)
may be used to assess the real rate of return  from an  investment  in the Fund;
(3) other  U.S.  government  statistics  such as GNP,  and net import and export
figures  derived from  governmental  publications,  e.g.,  The Survey of Current
Business,  may be used to  illustrate  investment  attributes of the Fund or the
general economic  business,  investment,  or financial  environment in which the
Fund  operates;  (4)  the  effect  of  tax-deferred  compounding  on the  Fund's
investment  returns,  or on returns in general,  may be  illustrated  by graphs,
charts,  etc.  where such graphs or charts would  compare,  at various points in
time,  the return  from an  investment  in the Fund (or returns in general) on a
tax-deferred  basis  (assuming  reinvestment  of capital gains and dividends and
assuming one or more tax rates) with the return on a taxable basis;  and (5) the
instruments  in which the Fund  invests may be  compared to relevant  indices or
surveys in order to evaluate  the Fund's  historical  performance  or current or
potential value with respect to the particular instruments.

     No compensation  is paid by the Fund to any of its officers.  Directors who
are not  affiliated  with IAI receive from the IAI Mutual Funds a $15,000 annual
retainer,  $2,500  for each  Board  meeting  attended,  $3,600  for  each  Audit
Committee  meeting  attended  (as  applicable)  and $1,800  for each  Securities
Valuation  Committee meeting  attended.  The Fund will pay its pro rata share of
these  fees  based  on its net  assets.  Such  unaffiliated  directors  also are
reimbursed for expenses incurred in connection with attending meetings.

     The Board of Directors for each of the Funds has approved a Code of Ethics.
The Code permits  access persons to engage in personal  securities  transactions
subject to  certain  policies  and  procedures.  Such  procedures  prohibit  the
acquiring of any  securities in an initial  public  offering.  In addition,  all
securities  acquired through private  placement must be pre-cleared.  Procedures
have been adopted which would implement blackout periods for certain securities,
as well as a ban on short-term trading profits. Additional policies prohibit the
receipt of gifts in  certain  instances.  Procedures  have been  implemented  to
monitor  employee  trading.  Each  access  person of the  Adviser is required to
certify  annually  that they have read and  understood  the Code of  Ethics.  An
annual report is provided to the Funds' Board of Directors  summarizing existing
procedures and changes,  identifying  material  violations and  recommending any
changes needed.

INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES AGREEMENT

     Pursuant to the Investment  Advisory and Administrative  Services Agreement
between  the Fund and IAI,  IAI has agreed to provide  the Fund with  investment
advice, statistical and research facilities, and certain equipment and services,
including,  but not limited to,  office space and necessary  office  facilities,
equipment,  and the services of required personnel and, in connection therewith,
IAI has the sole  authority and  responsibility  to make and execute  investment
decisions for the Fund within the framework of the Fund's  investment  policies,
subject to review by the directors of the Fund.  In addition,  IAI has agreed to
provide to the Fund all required  administrative,  stock  transfer,  redemption,
dividend disbursing and accounting services including,  without limitation,  the
following:  (1) the maintenance of the Fund's accounts,  books and records;  (2)
the  calculations  of the daily net asset  value in  accordance  with the Fu
 .nd's
current  Prospectus  and  Statement  of  Additional  Information;  (3) daily and
periodic  reports;  (4) all  information  necessary  to  complete  tax  returns,
questionnaires  and other reports  requested by the Fund; (5) the maintenance of
stock registry  records;  (6) the processing of requested  account  registration
changes,  stock  certificate  issuances  and  redemption  requests;  and (7) the
administration of payments of dividends and distributions  declared by the Fund.
In return  for such  services,  the Fund has agreed to pay IAI a fee of .50% per
year of the Fund's average daily net assets.

   
     As of November 30, 1997, the Fund had net assets of  $108,366,952.  For the
fiscal  years  ended  November  30,  1995,  1996,  and  1997,  the Fund paid IAI
$446,744,  $489,868,  and  $437,589,  respectively,  pursuant to the  Management
Agreement.

     Except for brokerage  commissions and other expenditures in connection with
the purchase and sale of portfolio securities, interest expense, and, subject to
the specific approval of a majority of the disinterested  directors of the Fund,
taxes and extraordinary  expenses, IAI has agreed to pay all of the Fund's other
costs and expenses,  including,  for example, costs incurred in the purchase and
sale of assets,  taxes,  charges of the custodian of the Fund's assets, costs of
reports and proxy material sent to Fund shareholders,  fees paid for independent
accounting  and  legal  services,   costs  of  printing  Prospectuses  for  Fund
shareholders and registering the Fund's shares,  postage,  fees to Directors who
are not  "interested  persons"  of the Fund,  insurance  premiums,  and costs of
attending investment conferences. IAI is not liable for any loss suffered by the
Fund in the absence of willful misfeasance, bad faith or gross negligence in the
performance of its duties and obligations.

     The  Investment   Advisory  and  Administrative   Services  Agreement  will
terminate  automatically  in the  event  of its  assignment.  In  addition,  the
Agreement is terminable at any time without penalty by the Board of Directors of
the Fund or by vote of a majority of the Fund's outstanding voting securities on
not more than 60 days'  written  notice to IAI, and by IAI on 60 days' notice to
the Fund. The Agreement  shall continue in effect from year to year only so long
as such  continuance  is  specifically  approved at least annually by either the
Board of  Directors  of the  Fund or by vote of a  majority  of the  outstanding
voting  securities,  provided  that in either  event  such  continuance  is also
approved  by the vote of a  majority  of  directors  who are not  parties to the
Agreement  or  interested  persons of such  parties  cast in person at a meeting
called for the purpose of voting on such approval.

     Although  investment  decisions  for the Fund are made  independently  from
those of the other funds and accounts as to which IAI gives  investment  advice,
it may occasionally develop that the same security is suitable for more than one
fund  and/or  other  account.  If and when more  than one fund or other  account
simultaneously  purchase or sell the same  security,  the  transactions  will be
averaged as to price and allocated as to amount in accordance with  arrangements
equitable to such funds and accounts.  The simultaneous  purchase or sale of the
same securities by more than one fund or by any fund and other accounts may have
detrimental  effects on the Fund,  as they may affect the price paid or received
by a fund or the size of the position obtainable by a fund.

                                CUSTODIAL SERVICE

   
     The custodian for the fund is Norwest Bank Minnesota,  N.A. Norwest Center,
Sixth  and  Marquette,  Minneapolis,  MN  55479.  Norwest  has  entered  into an
agreement with Morgan Stanley Trust Company, 1 Pierrepont Plaza,  Brooklyn,  New
York ("Morgan  Stanley") which enables the Fund to utilize the  subcustodian and
depository  network  of  Morgan  Stanley.  
    

               PORTFOLIO TRANSACTIONS AND ALLOCATION OF BROKERAGE

     Most of the Fund's portfolio transactions are effected with dealers without
the payment of brokerage commissions but at a net price which usually includes a
spread or markup.  In effecting  such  portfolio  transactions  on behalf of the
Fund, IAI seeks the most favorable net price consistent with the best execution.
However,  frequently  IAI  selects a dealer to effect a  particular  transaction
without  contacting  all dealers  who might be able to effect  such  transaction
because of the  volatility  of the bond market and the desire of IAI to accept a
particular  price for a security  because the price  offered by the dealer meets
its guidelines for profit, yield or both.

     So long as IAI believes that it is obtaining the best net price  (including
the spread or markup) consistent with the best execution, as described above, it
gives  consideration  in placing  portfolio  transactions to dealers  furnishing
research,  statistical information, or other services to IAI. This allows IAI to
supplement its own investment  research activities and enables IAI to obtain the
views and  information  of  individuals  and research  staffs of many  different
securities  firms  prior to making  investment  decisions  for the Fund.  To the

                                       21
<PAGE>

extent  portfolio  transactions  are effected with dealers who furnish  research
services to it, IAI  receives a benefit  which is not capable of  evaluation  in
dollar amounts.

   
     Consistent  with the  Rules  of  Conduct  of the  National  Association  of
Securities Dealers,  Inc. and subject to the policies set forth in the preceding
paragraphs  and such other  policies as the Board of  Directors  of the Fund may
determine,  IAI may  consider  sales of shares  of the  Fund,  or any of the IAI
Mutual  Funds,  as a factor in the  selection of  broker-dealers  to execute the
Fund's securities transactions.
    

     IAI believes that most research  services  obtained by it generally benefit
one or more of the  investment  companies  or other  accounts  which it manages.
Research  services  obtained from  transactions in fixed income securities would
primarily  benefit the managed funds investing such fixed income  securities and
managed accounts investing in fixed income securities.

                                  CAPITAL STOCK
   
     The  Fund is a  separate  portfolio  of IAI  Investment  Funds I,  Inc.,  a
corporation  organized on April 22,  1977,  pursuant to the laws of the State of
Minnesota,  whose  shares of common  stock are  currently  issued in two  series
(Series A and B). Each share of a series is entitled to participate  pro rata in
any dividends and other  distributions of such series and all shares of a series
have  equal  rights in the event of  liquidation  of that  series.  The Board of
Directors of IAI  Investment  Funds I, Inc., is empowered  under the Articles of
Incorporation  of such  company to issue other  series of the  company's  common
stock without shareholder approval. IAI Investment Funds I, Inc., has authorized
10,000,000,000  shares of $.01 par value  common  stock to be issued as Series B
common shares. The investment  portfolio  represented by such shares is referred
to as IAI  Institutional  Bond  Fund.  As of  November  30,  1997,  the Fund had
11,415,204 shares outstanding.

     As of _________, 1998, no person held of record or, to the knowledge of the
Fund,  beneficially owned more than 5% of the Fund's outstanding shares,  except
as set forth in the following table:

     In addition,  as of ________,  1998, the Fund's officers and directors as a

                    NET ASSET VALUE AND PUBLIC OFFERING PRICE

     The portfolio  securities in which the Fund invests fluctuate in value, and
hence, for the Fund, the net asset value per share also fluctuates.

   
     The net asset  value per share of the Fund is  determined  once daily as of
the close of trading  on the New York Stock  Exchange  on each  business  day on
which the New York Stock Exchange is open for trading,  and may be determined on
additional  days  as  required  by the  Rules  of the  Securities  and  Exchange
Commission.  The New York Stock Exchange is closed,  and the net asset value per
share of the Fund is not determined,  on the following  national  holidays:  New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,  Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
    

                                       22
<PAGE>


   
     On November 30,  1997,  the net asset value and public  offering  price per
share of the Fund was calculated as follows:

NAV =     Net Assets ($108,366,952)      =    $9.49
          -------------------------
          Shares Outstanding (11,415,204)
    

   
     The Fund  has  authorized  one or more  brokers  to  accept  on its  behalf
purchase  and  redemption  orders and such brokers are  authorized  to designate
other  intermediaries  to accept  purchase and  redemption  orders on the Fund's
behalf.  The Fund will be deemed to have received a purchase or redemption order
when an authorized  broker or, if applicable,  a broker's  authorized  designee,
accepts the order. In such circumstances,  customer orders will be priced at the
Fund's NAV next computed after they are accepted by an authorized  broker or the
broker's authorized designee.
                                       
                                   TAX STATUS

     The tax status of the Fund and the distributions of the Fund are summarized
in the Prospectus under "Dividends, Distributions and Tax Status."

     Under  the  Internal  Revenue  Code  of  1986,  as  amended  (the  "Code"),
individual  shareholders may not exclude any amount of  distributions  from Fund
gross income that is derived from dividends;  corporate  shareholders,  however,
are permitted to deduct 70% of qualifying  dividend  distributions from domestic
corporations.  Since  most  of the  dividends  paid  by  the  Fund  will  not be
attributable  to dividends  paid by domestic  corporations,  it is expected that
only a small  portion  of  dividends  paid  to  corporate  shareholders  will be
eligible for the dividends  received deduction in the hands of shareholders that
are   corporations.   Distributions   designated   as  long-term   capital  gain
distributions  will be taxable to all  shareholders  as long-term  capital gains
regardless of how long the shareholder has held the shares.  Such  distributions
will not be eligible for the dividends received deduction referred to above.

   
     If Fund  shares are sold or  otherwise  disposed of more than one year from
the date of  acquisition,  the difference  between the price paid for the shares
and the sales price  generally will result in long-term  capital gain or loss to
the Fund  shareholder  if, as is usually the case, the Fund shares are a capital
asset in the hands of the Fund  shareholder at that time. For  shareholders  who
are  individuals,  estates,  or  trusts,  the  gain or loss  will be  considered
long-term  (20%  gain) if the  shareholder  has held the shares for more than 18
months and mid-term (28% gain) if the  shareholder  has held the shares for more
than one year but not more than 18 months. However, under a special provision in
the  Code,  if Fund  shares  with  respect  to which a  long-term  capital  gain
distribution  has been,  or will be,  made are held for six months or less,  any
loss on the sale or other  disposition of such shares will be long-term  capital
loss to the extent of such distribution.
    

     Ordinarily,   distributions   and  redemption   proceeds   earned  by  Fund
shareholders are not subject to withholding of federal income tax. However,  the
Fund is required to withhold 31% of a shareholder's distributions and redemption
proceeds upon the occurrence of certain events  specified in Section 3406 of the
Code and regulations promulgated thereunder. These events include the failure of
a  Fund  shareholder  to  supply  the  Fund  with  such  shareholder's  taxpayer
identification  number,  and the failure of a Fund  shareholder who is otherwise
exempt from  withholding to properly  document such  shareholder's  status as an
exempt recipient. Additionally,  distributions may be subject to state and local
income taxes,  and the treatment  thereunder  may differ from the federal income
tax consequences discussed above.

     Under the Code,  the Fund will be  subject to a  non-deductible  excise tax
equal to 4% of the  excess,  if any,  of the  amount of  investment  income  and
capital gains required to be distributed  pursuant to the Code for each calendar
year over the amount  actually  distributed.  In order to avoid this excise tax,
the Fund  generally  must  declare  dividends by the end of each  calendar  year
representing 98% of the Fund's ordinary income for such calendar year and 98% of
its capital gain net income (both long-term and short-term) for the twelve-month
period  ending  October  31 of the same  calendar  year.  The  excise tax is not
imposed,  however, on undistributed  income that is already subject to corporate
income  tax.  It is the Fund's  policy not to  distribute  capital  gains  until
capital loss carryovers, if any, either are utilized or expire.

     Income  received from sources  within  foreign  countries may be subject to
withholding and other taxes imposed by such countries.  Tax conventions  between
certain  countries and the United States may reduce or eliminate such taxes.  It
is impossible to determine the effective  rate of foreign tax applicable to such
income in advance since the precise  amount of a Fund's assets to be invested in
various  countries is not known. Any amount of taxes paid by the Fund to foreign
countries  will  reduce  the  amount  of  income   available  to  the  Fund  for
distributions to shareholders.

                                       23
<PAGE>


     If the Fund  invests  in zero  coupon  obligations  or  STRIPS  upon  their
issuance, such obligations will have original issue discount in the hands of the
Fund.  Generally,  the original issue discount equals the difference between the
"stated redemption price at maturity" of the obligation and its "issue price" as
those terms are defined in the Code. If the Fund acquires an already issued zero
coupon bond or STRIPS from another  holder,  the bond will have  original  issue
discount in the Fund's  hands,  equal to the  difference  between the  "adjusted
issue price" of the bond at the time the Fund acquires it (that is, the original
issue price of the bond plus the amount of original  issue  discount  accrued to
date) and its stated  redemption  price at maturity.  In each case,  the Fund is
required to accrue as ordinary  interest income a portion of such original issue
discount  even though it receives no cash  currently as interest  payment on the
obligation.   If  the  Fund  invests  in  U.S.   Treasury   inflation-protection
securities, it will be required to treat as original issue discount any increase
in the principal  amount of the securities  that occurs during the course of its
taxable year. If the Fund purchases such  inflation-protection  securities  that
are issued in  stripped  form either as  stripped  bonds or coupons,  it will be
treated as if it had purchased a newly issued debt  instrument  having  original
issue discount.

   
     Because  the Fund is required to  distribute  substantially  all of its net
investment income in order to be taxed as a regulated investment company, it may
be required to distribute an amount  greater than the total cash income the Fund
actually receives.  Accordingly, in order to make the required distribution, the
Fund may be required to borrow or to liquidate  securities.  
    

     Except  for  the   transactions   the  Fund  has   identified   as  hedging
transactions,  the Fund is required for federal income tax purposes to recognize
as income for each taxable year its net  unrealized  gains and losses on futures
contracts,  options, and forward currency contracts as of the end of the year as
well as those actually  realized  during the year.  Except for  transactions  in
futures contracts,  options or forward currency contracts that are classified as
part of a  "mixed  straddle,"  gain  or loss  recognized  with  respect  to such
contract or contracts 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
contract.  In the case of a transaction  classified as a "mixed  straddle,"  the
recognition of losses may be deferred to a later taxable year.

     Sales of futures contracts, options, or forward currency contracts that are
intended to hedge against a change in the value of securities or currencies held
by the Fund may affect the holding period of such  securities or currencies and,
consequently,  the nature of the gain or loss on such  securities  or currencies
upon disposition.

   
     It is expected  that any net gain  realized from the closing out of futures
contracts,  options,  or forward currency contracts will be considered gain from
the sale of securities  or  currencies  and,  therefore,  qualifying  income for
purposes of the requirement that a regulated  investment company derive at least
90% of its gross income from  dividends,  interest and certain  types of payment
related to its investment in stocks or securities.
    

     Any unrealized gain or loss on closing out a futures  contracts,  option or
forward currency contract such as forward commitment for the purchase or sale of
foreign currency will generally result in a recognized  capital gain or loss for
tax  purposes.  Code Section 988 may also apply to forward  currency  contracts.
Under  Section 988,  each foreign  currency  gain or loss is generally  computed
separately  and  treated  as  ordinary  income or loss.  In the case of  overlap
between  Section 1256 and 988,  special  provisions  determine the character and
timing of any income, gain or loss. The Fund will attempt to monitor Section 988
transactions to avoid an adverse tax impact.

     The foregoing is a general and abbreviated summary of the Code and Treasury
regulations in effect as of the date of the Fund's Prospectus and this Statement
of Additional  Information.  The foregoing  relates solely to federal income tax
law applicable to "U.S.  persons,"  i.e.,  U.S.  citizens and residents and U.S.
domestic corporations,  partnerships,  trusts and estates.  Shareholders who are
not U.S.  persons are  encouraged to consult a tax adviser  regarding the income
tax consequences of acquiring shares of the Fund.

                        LIMITATION OF DIRECTOR LIABILITY

     Under  Minnesota law, the Fund's Board of Directors owes certain  fiduciary
duties  to the Fund  and to its  shareholders.  Minnesota  law  provides  that a
director "shall  discharge the duties of the position of director in good faith,
in a manner the director  reasonably  believes to be in the best interest of the
corporation,  and with the care an ordinarily  prudent person in a like position
would exercise under similar circumstances." Fiduciary duties of a director of a
Minnesota  corporation include,  therefore,  both a duty of "loyalty" (to act in
good faith and act in a manner  reasonably  believed to be in the best interests
of the  corporation)  and a duty of "care"  (to act with the care an  ordinarily
prudent person in a like position  would exercise under similar  circumstances).
Minnesota  law  authorizes  corporations  to  eliminate  or limit  the  personal
liability  of a director to the  corporation  or its  shareholders  for monetary
damages  for breach of the  fiduciary  duty of "care."  Minnesota  law does not,
however,  permit a corporation to eliminate or limit the liability of a director
(i) for any breach of the director's duty of "loyalty" to the corporation or its
shareholders,  (ii)  for acts or  omissions  not in good  faith or that  involve
intentional  misconduct or a knowing  violation of law, (iii) for  authorizing a
dividend,  stock repurchase or redemption or other  distribution in violation of
Minnesota  law or for violation of certain  provisions  of Minnesota  securities
laws, or (iv) for any  transaction  from which the director  derived an improper
personal benefit. The Articles of Incorporation of IAI Investment Funds I, Inc.,
limit the  liability of directors to the fullest  extent  permitted by Minnesota
statutes, except to the extent that such liability cannot be limited as provided
in the Investment  Company Act of 1940 (which Act prohibits any provisions which
purport to limit the liability of directors arising from such directors' willful
misfeasance,  bad faith,  gross negligence,  or reckless disregard of the duties
involved in the conduct of their role as directors).

     Minnesota  law  does  not  eliminate  the  duty of  "care"  imposed  upon a
director.  It only authorizes a corporation to eliminate  monetary liability for
violations of that duty. Minnesota law, further,  does not permit elimination or
limitation  of liability of "officers"  of the  corporation  for breach of their
duties as officers  (including  the liability of directors who serve as officers
for  breach  of their  duties  as  officers.)  Minnesota  law  does  not  permit
elimination  or  limitation of the  availability  of equitable  relief,  such as
injunctive  or  rescissionary  relief.  Further,  Minnesota  law does not permit
elimination or limitation of a director's  liability under the Securities Act of
1933 or the Securities  Exchange Act of 1934, and it is uncertain whether and to
what extent the elimination of monetary  liability would extend to violations of
duties imposed on directors by the Investment  Company Act of 1940 and the rules
and regulations adopted under such Act.

                           RATINGS OF DEBT SECURITIES

RATINGS BY MOODY'S

CORPORATE BONDS

     Aaa.  Bonds 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 most  unlikely  to impair the
fundamentally strong position of such issues.

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

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

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

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

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

     Conditional  Ratings. The designation "Con." followed by a rating indicates
bonds for which the  security  depends  upon the  completion  of some act or the
fulfillment  of some  condition.  These are bonds  secured  by (a)  earnings  of
projects under  construction,  (b) earnings or projects  unseasoned in operating
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.

                                      A-1
<PAGE>


Note:  Moody's  applies  numerical  modifiers  1,  2,  and  3 in  the  Aa  and A
classifications  of its corporate bond rating  system.  The modifier 1 indicates
that the security  ranks in the higher end of its generic rating  category;  the
modifier 2 indicates a mid-range ranking;  and the modifier 3 indicates that the
issue ranks in the lower end of its generic  rating  category.  With  respect to
municipal  securities,  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

     Moody's  employs  the  following  three  designations,  all  judged  to  be
investment grade, to indicate the relative repayment capacity of rated issuers:

     Prime  - 1  Superior  ability  for  repayment  of  senior  short-term  debt
obligations

     Prime  -  2  Strong  ability  for  repayment  of  senior   short-term  debt
obligations

     Prime - 3  Acceptable  ability  for  repayment  of senior  short-term  debt
obligations

     If an issuer  represents to Moody's that its Commercial  Paper  obligations
are supported by the credit of another entity or entities, Moody's, in assigning
ratings to such  issuers,  evaluates  the  financial  strength of the  indicated
affiliated   corporations,   commercial  banks,  insurance  companies,   foreign
governments,  or other  entities,  but only as one  factor in the  total  rating
assessment.


RATINGS BY S&P

CORPORATE BONDS

     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 higher 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.

     BB. Debt rated BB has less  near-term  vulnerability  to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,  financial,  or  economic  conditions  which  could  lead  to
inadequate capacity to meet timely interest and principal payments.

     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-rating.

                                      A-2
<PAGE>

     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.

     CC. Debt rated CC is typically  applied to debt subordinated to senior debt
which is assigned an actual or implied CCC debt rating.

     C. The rating C typically applied to debt subordinated to senior debt which
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.

     C1. The rating C1 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 will be used upon
the filing of a bankruptcy petition if debt service payments are jeopardized.

     In order to provide more detailed indications of credit quality, S&P's bond
letter ratings  described above (except for the AAA category) may be modified by
the  addition  of a plus or a minus sign to show  relative  standing  within the
rating category.

COMMERCIAL PAPER

     A. This highest rating category  indicates the greatest capacity for timely
payment. Issues in this category are further defined with the designations 1, 2,
and 3 to indicate the relative degree to safety.

     A-1. This designation  indicates that the degree of safety regarding timely
payment is either  overwhelming  or very  strong.  Those  issues  determined  to
possess overwhelming safety characteristics are designed A-1+.

     A-2.  Capacity  for timely  payments  on issues  with this  designation  is
satisfactory.  However,  the  relative  degree  of  safety is not as high as for
issues designed A-1.

     A-3. Issues  carrying this  designation  have adequate  capacity for timely
repayment.  They are, however, more vulnerable to the adverse effects of changes
in circumstances than obligations carrying the higher designations.
