WHAT'S RIGHT WITH THIS MARKET

[PHOTO]
ROY C. GILLSON
PRESIDENT

The stock market has been on a roller coaster of late, and that naturally makes
people uneasy. But if you're a long-term investor, I would argue there are a lot
more good things influencing the market than bad things.

True, U.S. corporate earnings are flattening out, and that's putting a damper on
the stock market. When you buy a stock, you're buying a future stream of
dividends as well as a stronger company because most of the profits are being
reinvested. After double-digit growth during much of the 1990s, profits in 1998
are struggling. A major reason why profits are sluggish is the economic and
currency turmoil in Asia, which hurts U.S. companies doing business there.

Another reason for weak profit growth is the great job Corporate America has
done to become more efficient. After years of cost-cutting, there isn't much
cutting left to do. To enhance profits, companies must either boost prices or
sell more products and services. But with inflation at virtually zero, it's
tough to raise prices. So, profit growth must come through increased unit
volume.

And that's where the good news is likely to begin. Even with the dampening
effects of Asia, the U.S. economy is still basically healthy, making it possible
for U.S. corporations to sell more products and services here at home. True,
we're losing business in Asia, because the dollar is so strong compared to their
currencies. But what we're losing in Asia, we're gaining in Europe, as that
region of the world begins to enjoy U.S.-style prosperity. Europe will look even
stronger once the euro, the Continent's new single currency, begins to filter
through the economy.

Asia has helped keep inflation worries away, and that has kept interest rates
low. Recently, the 30-year Treasury bond yield reached its lowest level ever, as
global investors buy our securities for the greatest safety and liquidity.
Partly because of our low inflation environment, worldwide demand for U.S.
stocks and bonds continues to be strong.

Although 1998 was extremely volatile, the year turned out quite well, with the
Dow Jones Industrial Average up 18%. The Dow has more than doubled since 1995
and virtually tripled since the beginning of this decade. Where was the Dow in
1982? 800! Has the value of your house gone up by a factor of ten in fifteen
years? Probably not. The point is markets do not go up in a straight line, and
there is bound to be volatility. But if you're an investor for the long term,
you should be able to step back and see the good in this market.

                           IAI INSTITUTIONAL BOND FUND

ECONOMIC OUTLOOK

A summary of economic outlook as provided by Larry Hill, IAI's Chief Fixed
Income Officer, follows.

Growth in the U.S. economy is likely to remain firm in the months ahead. Over
the four quarters ending in September 1998, the real economy expanded by 3.5%
with inflation, as measured by the GDP deflator, or rose at an annualized rate
of only 1.0%. While the economy is likely to slow, it is hard to become too
negative on the outlook. There is little evidence of a recession on the horizon.
A modest slowdown is more likely, with real growth dropping to about 3.0% for
1999.

Some sectors of the economy are losing forward momentum. The manufacturing
sector is clearly showing signs of weakness. This sector is directly exposed to
the global glut of commodity goods. With weaker demand overseas, exports are
slowing while imports are rising. Corporate profits are being squeezed, which is
likely to reduce capital spending plans for 1999. These indicators all point to
moderately slower growth ahead.

Yet, growing evidence of economic deterioration--if this occurs--will prompt
further rate reduction. Having taken the first step to ease in three years, the
Fed is now sensitive to overseas conditions and the fluid economic environment.
If the economy appears to be stumbling, the Fed has plenty of room to drop rates
and will do so with little hesitation. Likewise, renewed turmoil in the markets
will also prompt Fed action. Thus our outlook for no recession is driven by our
confidence that the Fed can and will act if necessary.

Fed diligence is also a key ingredient for the markets. Subdued inflation and
the prospect of further cuts in short rates--if needed--will provide support for
bonds. Stock prices remain trapped in a tug-of-war between high valuations and
favorable liquidity. Only a select group of stocks have benefited from excess
liquidity. The stock market will be pulled up and down until one force overcomes
the other and sets the next trend.

Please read the Fund Managers' Review, which follows this letter, for a detailed
perspective on Fund performance and our strategy going forward. We appreciate
your continued trust and confidence in IAI. If there is any way we can serve you
better, please let us know by calling our toll-free Investor Services Hotline at

LARRY R. HILL, CFA
IAI INSTITUTIONAL BOND
FUND MANAGER

WHAT IS THE FUND'S OBJECTIVE?

The IAI Institutional Bond Fund seeks to provide a high level of total return
derived from a combination of capital appreciation and current income. This
objective is pursued by investing primarily in a diversified portfolio of U.S.
Government securities and investment- and non-investment- grade bonds and other
debt securities of similar quality. The Fund invests in a variety of maturities
and sectors which are varied depending on relative values in the marketplace at
a given point in time.

HOW HAS THE FUND PERFORMED?

The Fund gained 7.92% for the year ended November 30, 1998. This compares with
returns for the Lehman Brothers Aggregate Bond Index of 9.45% and the Salomon
Broad Investment Grade Bond Index of 9.49%.

WERE THERE ANY SIGNIFICANT CHANGES?

During the year, there were no major changes to the investment strategy. The
interest rate sensitivity of the Fund remained longer than the benchmark and
sector weightings continued to emphasize mortgages and corporates.

CAN YOU POINT TO ANY SPECIFIC MARKET FACTORS THAT INFLUENCED THE FUND'S
PERFORMANCE?

The continuing flight-to-quality from less stable markets combined with the
increased premium on liquidity caused by forced sales at some hedge funds led to
a discontinuity within the bond market. Treasury yields declined significantly
during both August and September. At the same time however, the yields on
corporates and mortgages declined only modestly. This widening of interest rate
spreads accounted for the majority of the performance shortfall for the Fund
during the year because the Fund's portfolio is comprised of more
mortgaged-backed securities and corporate bonds, and less Treasury securities,
relative to the benchmark.

WHAT IS YOUR OUTLOOK FOR THE FUND?

Markets will remain volatile until the excess leverage employed by foreign
businesses and hedge funds has been unwound. This process has been going on for
foreign businesses for some time, but hedge fund liquidations were just
beginning at the end of September. The Federal Reserve Board (the Fed) is trying
to prevent isolated cases of credit contraction from becoming a general economic
contraction. They have already acted to maintain ample liquidity by reducing the
Fed Funds rate by one-half percentage point.

     Corporate bonds, mortgages and asset-backed securities present tremendous
long-term value at current, near record yield spreads. While these sectors are
still under pressure from leveraged sellers, we are maintaining our overweight
positions to potentially earn exceptional returns over the longer term. We
remain diligent in evaluating the credit trends for corporate holdings and the
prepayment uncertainties for mortgage backed securities. The portfolio is well
diversified for the current volatile environment, giving us the flexibility to
take advantage of buying opportunities as they arise.

                                NOVEMBER 30, 1998


                                       (a)
Market value of securities is determined as described in Note 1 to the financial
statements, under "Security Valuation."

                                       (b)
Purchased on a when-issued basis. At November 30, 1998, the total cost of
securities purchased on a when-issued basis was $4,767,480.

                                       (c)

Security is partially pledged to cover initial margin on open futures contracts
(see Note 5 to financial statements).

                                       (d)
Foreign security cost and market values are stated in U.S. dollars. Principal
amounts are denominated in the foreign currency indicated parenthetically.

                                       (e)
Represents security sold within terms of a private placement memorandum exempt
from registration under Section 144A or 4(2) of the Securities Act of 1933.
These issues may only be sold to other qualified institutional buyers, and are
considered liquid under guidelines established by the Board of Directors.
The market value of such securities was $3,593,266 (7.3% of net assets) at
November 30,1998.

                                       (f)
Yankee represents dollar-denominated bonds issued in the United States by
foreign banks and corporations.

                                       (g)
Interest rate shown represents yield-to-maturity at date of purchase.

                                       (h)
The interest rate shown for Payment-in-Kind bonds (PIK bonds) represents
effective yield at November 30, 1998. PIK--Payment-in-Kind income is generally
paid by issuing additional par or shares of the security rather than paying
cash.

                                       (i)
A step bond is a security that remains zero-coupon until a predetermined date at
which time the stated coupon rate becomes payable at regular intervals. The
interest rate shown for step bonds represents the effective yield at November
30, 1998, based upon the estimated timing and amount of future interest and
principal payments.

                                       (j)
Represents a preferred security. Quantity is disclosed in units. One unit
represents 100 par.

                                       (k)
Represents security sold within terms of a private placement memorandum exempt
from registration under Section 144A of the Securities Act of 1933. This issue
was deemed illiquid at November 30, 1998, based on guidelines established by the
Board of Directors. The market value of this security was $690,000 (1.4% of net
assets) at November 30, 1998.

                                       (l)
At November 30, 1998, the cost of securities for federal income tax purposes and
the aggregate gross unrealized appreciation and depreciation based on that cost
were as follows:

[1]  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The IAI Mutual Funds are registered under the Investment Company Act of 1940 (as
amended) as diversified, open-end management investment companies. IAI
Institutional Bond Fund (Institutional Bond Fund) is a separate portfolio of IAI
Investment Funds I, Inc. The Fund's primary investment objective is to provide
shareholders with a high level of total return derived from a combination of
capital appreciation and current income. The Fund pursues its objective by
investing primarily in a diversified portfolio of U.S. Government securities and
investment- and non-investment-grade bonds and other debt securities of similar
quality. This report covers only Institutional Bond Fund (the Fund).

Significant accounting policies followed by the Fund are summarized below:

SECURITY VALUATION

Investments in securities traded on national or international securities
exchanges are valued at the last reported sales price at the close of each
business day. Securities traded on the over-the-counter market are valued at the
last reported sales price or if the last sales price is not available, the last
reported bid price. Such valuations are obtained from pricing services or are
supplied by dealers.

Debt securities for which quotations are not readily available are valued
primarily using dealer-supplied valuations or at their fair value as determined
in good faith using consistently applied procedures under the general
supervision of the Board of Directors.

Short-term securities with maturities of 60 days or less from the date of
initial acquisition are valued at amortized cost. Those with maturities greater
than 60 days from the date of initial acquisition are marked-to-market on a
daily basis.


SECURITIES PURCHASED ON A
WHEN-ISSUED BASIS

Delivery and payment for securities which have been purchased by the Fund on a
forward commitment or when-issued basis may occur a month or more after the
transaction date. During this period, such securities are subject to market
fluctuations and the Fund maintains, in a segregated account, assets with a
market value equal to the amount of its purchase commitments.

FUTURES AND OPTIONS
CONTRACTS

In order to increase exposure to and hedge against changes in the market, the
Fund may buy and sell futures contracts and options. The risks of entering into
futures and option contracts include the possibility that changes in the value
of these contracts may not correlate with changes in the underlying security.

Futures contracts are valued at the settlement price of the exchange on which
they are traded. Upon entering into a futures contract, the Fund is required to
deposit either cash or securities into a segregated account, representing the
initial margin, equal to a certain percentage of the contract value. Subsequent
changes in the value of the contract, or variation margin, are recorded daily as
unrealized gains or losses. Variation margin is paid or received in cash daily
by the Fund. The Fund realizes a gain or loss when the contract is closed or
expires.

Options traded on an exchange are valued using the last sale price, and those
traded over-the-counter are valued using dealer-supplied valuations, resulting
in unrealized appreciation or depreciation being recorded. The Fund will realize
a gain or loss upon expiration or closing of the option transaction. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

[1]          SUMMARY OF SIGNIFICANT ACCOUNTING
             POLICIES (CONT.)

FOREIGN CURRENCY
TRANSLATIONS AND FOREIGN
CURRENCY CONTRACTS

The Fund may invest in foreign securities. The market value of securities and
other assets and liabilities denominated in foreign currencies is translated
daily into U.S. dollars at the closing rate of exchange. Purchases and sales of
securities, income and expenses are translated at the exchange rate on the
transaction date and are recorded in realized and unrealized appreciation or
depreciation on foreign currency contracts.

Exchange gains and losses may also be realized between the trade and settlement
dates on security and foreign currency contract transactions. The Fund does not
isolate that portion of the results of operations resulting from changes in
foreign exchange rates on investments from the fluctuations arising from changes
in market prices of securities held. Such fluctuations are included with the net
realized and unrealized gain or loss from investments.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuations.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete the obligations of the contract.

FEDERAL TAXES

Since it is the Fund's policy to comply with the provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute all
of its taxable income to its shareholders, no provision for income taxes is
required. In order to avoid the payment of any federal excise taxes, the Fund is
required to distribute substantially all of its net investment income and net
realized gains on a calendar year basis.

Net investment income and net realized gains may differ for financial statement
and tax purposes primarily because of recognition of certain foreign currency
gains and losses as ordinary income and the deferral of "wash sale" losses for
tax purposes. The character of distributions made during the year for net
investment income or net realized gains may also differ from its ultimate
characterization for tax purposes.

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been decreased by $172,114
and accumulated net realized gains have been increased by $172,114.

SECURITY TRANSACTIONS AND
INVESTMENT INCOME

The Fund records security transactions on trade date, the date the securities
are purchased or sold. Dividend income is recorded on the ex-dividend date.
Interest income is accrued daily. The Fund amortizes discount purchased on
long-term bonds using the level yield method of amortization. Security gains and
losses are determined on the basis of identified cost, which is the same basis
used for federal income tax purposes.

DISTRIBUTIONS TO
SHAREHOLDERS

Distributions to shareholders are recorded on the record date. Distributions
from net investment income are made monthly. Capital gains, if any, are
primarily distributed at the end of the calendar year. Additional capital gains
distributions as needed to comply with federal tax regulations are distributed
during the year.


                                                                              17

[1]          SUMMARY OF SIGNIFICANT ACCOUNTING
             POLICIES (CONT.)

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts in the financial statements. Actual results could
differ from those estimates.

[2]   COMMITMENTS AND CONTINGENCIES

INSURANCE

For purposes of obtaining certain types of insurance coverage for the Fund and
its officers and directors, the Fund is a policyholder in an industry-sponsored
mutual insurance company (the Company). In connection with its obligation as a
policy holder, the Fund is committed to make future capital contributions, if
requested by the Company.

LINE OF CREDIT

The Fund has available a $9,375,000 line of credit with a bank at the prime
interest rate. To the extent funds are drawn against the line, securities are
held in a segregated account. No compensating balances or commitment fees are
required under the line of credit. During the year ended November 30, 1998, the
Fund paid $5,005 in interest on the line of credit at an average rate of 8.50%.
This interest is included in interest income on the Statement of Operations.
There were no borrowings outstanding at November 30, 1998.

[3]   FEES AND EXPENSES

Under terms of the Fund's Management Agreement, Investment Advisers, Inc.
(Advisers) is required to pay for all expenses of the Fund, except certain costs
(primarily those incurred in the purchase and sale of assets, taxes, interest
and extraordinary expenses), in return for the Fund paying an all inclusive
management fee (unified fee) to Advisers. The fee is equal to an annual rate of
0.50% of average daily net assets. This fee is paid monthly. The Management
Agreement further provides that Advisers will either reimburse the Fund for the
fees and expenses it pays to Directors who are not "interested persons" of the
Fund or reduce its fee by an equivalent amount.

                           IAI INSTITUTIONAL BOND FUND


THE BOARD OF DIRECTORS AND SHAREHOLDERS
IAI INVESTMENT FUNDS I, INC.:

We have audited the accompanying statement of assets and liabilities, including
the fund portfolio, of IAI Institutional Bond Fund (a portfolio within IAI
Investment Funds I, Inc.) as of November 30, 1998, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period then ended, and the financial
highlights for the periods presented on page 15 of the annual report. These
financial statements and the financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased but not received, we request confirmations
from brokers and where replies are not received, we carry out other appropriate
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and the financial highlights referred
to above present fairly, in all material respects, the financial position of IAI
Institutional Bond Fund at November 30, 1998, and the results of its operations,
the changes in its net assets and the financial highlights for the periods
stated in the first paragraph above, in conformity with generally accepted
accounting principles.
