A DAY FOR BUYING OPPORTUNITIES


[PHOTO]
NOEL P. RAHN
CHAIRMAN


In life, traumatic events grip our attention, sometimes compelling us to make
quick decisions, often rewarding us for remaining calm. As time passes, we
collect ourselves and attain a perspective.

The stock market is a case in point. The last few days of October broke records
for points lost and gained--and for trading volume, which reached a billion
shares per day. But now that we've had some time to reflect, what really
happened? And what does it mean over the long term?

The problem began in Southeast Asia, as those booming economies increasingly
became overbuilt. Investors, seeing trouble ahead, withdrew their money, causing
downward pressure on currencies in Thailand and Malaysia. The governments
attempted to boost their currencies by raising interest rates. That caused
investors in these fragile stock markets to flee. Once the panic spread to Hong
Kong, investors throughout the world reacted.

In the United States, investors who were having a good year so far in 1997
decided to lock in their profits. Many of the best performers in recent years,
such as technology companies which do a great deal of business in Asia, were hit
hard. Small capitalization stocks held up better, as did large cap companies
such as retailers who do their business exclusively in the United States.

The October 27 sell-off was inevitably compared with the stock market of 1987.
But there really was no comparison. In percentage terms, this year's fireworks
amounted to a 7% drop. In comparison, the 1987 sell-off was 22% in one day.

But there are other fundamental differences too, which make the events of
October 27, 1997, much less worrisome. Ten years ago, inflation was in the
mid-single digits and rising. Today, some economists would argue that there is
no inflation at all--in fact, there even may be deflation. In 1987, interest
rates were in the double digits and rising. Today, the 30-year U.S. Treasury
bond yields about 6%. In 1987, the federal budget deficit was mushrooming.
Today, the deficit has virtually been wiped out, and there's talk of a surplus.
The American economy is much stronger today than it was a decade ago.

Perhaps most importantly, investors, rather than running scared and selling at
the bottom, increasingly look at days like October 27 as a buying opportunity.

Even with the events of late October, the stock market has turned in an
above-average performance for 1997. Historically, stocks have produced average
annual returns of 10-12%. Viewed over this decade, and since the bull market
began in 1982, investors have enjoyed truly excellent results.

We believe the turmoil that occurred on October 27 will prove to be a relatively
minor event. True, it was a very strong reaction to external events. But the
environment continues to be a good one for U.S. investors. The economy continues
to grow at a 3-4% rate without inflation. Interest rates are low and corporate
profits continue to grow, although more slowly than in recent years. And the
markets in Asia appear to have stabilized for now.

The recent volatility is a great reminder to dollar-cost average into the
markets. Mutual funds make it easy to invest a fixed amount of money
periodically. When the market is down, that fixed investment buys more shares at
bargain prices. Such an automatic process allows you to keep your long-term
perspective when days like October 27 inevitably occur.

                                CHAIRMAN'S LETTER
                           IAI INSTITUTIONAL BOND FUND


ECONOMIC OUTLOOK

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

Fundamentally, the U.S. economy remains in good shape. Growth is relatively
high, inflation is low, interest rates have fallen, the unemployment rate is at
its lowest level since the early 1970s and consumer confidence is near a record
high. Moreover, above trend growth and low inflation have essentially eliminated
the federal budget deficit. In addition, many states are experiencing surpluses
which are likely to be spent or rebated to taxpayers. The Fed is providing ample
liquidity and is unlikely to change this stance in the near future.

Despite these favorable domestic trends, Asian turmoil remains a major
uncertainty facing the economy in the first half of 1998. The worst of the
liquidity crises in that region is probably over. Yet the economic fallout
within the region still lies ahead. While many analysts fear these problems will
seriously impact the global economy, we believe the results will be much less
severe. For the U.S. economy, final demand should remain firm. Thus, we expect
growth to slow only marginally as a result of Asian events. However, distressed
Asian sellers will put fierce competitive pressures on manufacturing and
commodity based industries around the world. As a result, inflation in the U.S.
will remain below 2% for the first half of the year. Further growth, low
inflation and low interest rates will continue to provide a favorable background
for the financial markets in the months ahead.

Please read the Fund Managers' Review, which follows this letter, for a detailed
perspective on the Funds' 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

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 IAI Institutional Bond Fund gained 5.97% for the year ended November 30,
1997, while the Salomon Broad Investment Grade Bond Index, its benchmark,
returned 7.56% for the same period.

WERE THERE ANY SIGNIFICANT CHANGES?

The interest rate sensitivity of the Fund was reduced in August, but increased
in October following the flight-to-quality precipitated by the turmoil in
Southeast Asian markets. The Fund's exposure to Mortgage-backed securities
remained above the benchmark to take advantage of wider spreads. In addition,
the Corporate bond positions were reduced in the final quarter and non-dollar
bond exposure remained modest.

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

The biggest event during the past year was the collapse of several Asian
markets. Investors fled these countries in search of more stable and secure
investments. Supporting the rally was the continuation of non-inflationary
economic growth. From the end of August to the end of October, interest rates
fell 1/2% in response to this flight-to-quality. The Fund's shorter, more
conservative duration strategy and the underperformance of the Fund's corporate
bond holdings contributed to the Fund's underperformance during this period.

WHAT IS YOUR OUTLOOK FOR THE FUND?

Above average economic growth should persist, although expectations will be
dampened by financial market turbulence, particularly in Asia. Asian markets
continue to be volatile and recovery in those economies will be several quarters
in the future. However, as overseas markets stabilize, cyclical inflationary
pressures will re-emerge. Tight labor market conditions will continue to be a
concern for the market. Fed policy is still focused on controlling inflation. We
remain neutral to constructive on the bond market but are very conscious that
the next major move in rates is likely to be higher rather than lower. Given
today's lower yields and the probable direction of interest rates, a lower
return in 1998 is likely.

                                NOVEMBER 30, 1997


[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 is a separate portfolio of IAI Investment Funds I, Inc.
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. 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 the
IAI Institutional Bond Fund (the Fund).

Significant accounting policies followed by the Fund are summarized below:

SECURITY VALUATION

Investments in securities traded on national securities or international
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 can take place 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 risk 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.

<PAGE>


                          NOTES TO FINANCIAL STATEMENTS
                           IAI INSTITUTIONAL BOND FUND


                                NOVEMBER 30, 1997


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

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, which represents
the initial margin, which is 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.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

The Fund invests 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.

                          NOTES TO FINANCIAL STATEMENTS
                           IAI INSTITUTIONAL BOND FUND


                                NOVEMBER 30, 1997


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

Net investment income and net realized gains 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 increased by $521,365
and accumulated net realized gains have been decreased by $521,365.

For federal income tax purposes, the Fund has a capital loss carry-over of
approximately $193,000 at November 30, 1997, which, if not offset by subsequent
capital gains, will expire in 2002. It is unlikely the Board of Directors will
authorize a distribution of any net realized gains until the available capital
loss carryover is offset or expires.

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 as of the end of the calendar year. Additional capital
gains distributions as needed to comply with federal tax regulations are
distributed during the year.

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

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). Also, the Fund is committed to make
capital contributions, if requested by the Company.

The Fund has available a $30,000,000 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, 1997, the
Fund paid $5,692 in interest on the line of credit at an average rate of 8.50%.
There were no borrowings outstanding at November 30, 1997.

[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 and is paid monthly. The Management Agreement
further provides that Advisers will 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.

[4]   PURCHASES AND SALES OF SECURITIES

For the year ended November 30, 1997, purchases of securities and sales
proceeds, other than investments in short-term securities, for the Fund
aggregated $451,159,137 and $438,634,025, respectively.

[5]   OPEN FUTURES CONTRACTS

The financial futures contracts shown below were open as of November 30, 1997.
The market value of securities deposited to cover initial margin requirements
for the open positions at November 30, 1997, was $299,874. The unrealized
appreciation on these contracts is included in unrealized appreciation or
depreciation on investment securities.

                          INDEPENDENT AUDITORS' REPORT
                           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, 1997, 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 and sold but not received or delivered, 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, 1997, 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.
