                               PRESIDENT'S LETTER

DEAR SHAREHOLDER:

    The bulls were stopped this year, at least they were in professional
basketball as the Chicago Bulls failed to make the playoffs. However, in the
stock market, the bulls continued on a rampage. For the fifth year in a row, as
measured from July 1 to June 30, stocks were up more than 20% as the S & P 500
Index* advanced 22.8%. Bond investments did not fare as well as interest rates
rose in 1999's first half. The Merrill Lynch Domestic Master Bond index* had a
paltry 3.08% return over the past twelve months.

    Large capitalization stocks continued to dominate the equity markets in
performance terms as all major indices reached record levels. At current
valuation levels, the stock market appears to be expecting continuation of the
current economic environment. Inflation fears have ebbed and the rate of
inflation has eased to around 2% per year. Consumer confidence is at an all time
high and corporate profits continue to grow.

    Interest rates have backed up a bit on expectation that the Federal Reserve
Board would raise short-term rates. On June 30 the FOMC raised its target funds
rate by 25 basis points to 5%, but has no strong predisposition toward further
action in the near-term. The Fed had expressed concern about our full employment
economy and possible developing price pressures. While further tightening
remains a possibility, such action will depend on evidence that demand pressures
are raising the risks of inflation. In this environment Treasury bonds remain
locked in a 5 to 6 1/2% range.

                          IAA TRUST GROWTH FUND, INC.
                             INCEPTION DATE 4/21/66

The annualized total returns for the Fund for the period ended June 30, 1999,
are as follows:

<TABLE>
<CAPTION>
1 YEAR  5 YEARS  10 YEARS
- ------  -------  --------
<S>     <C>      <C>
26.10%  22.59%    14.43%
</TABLE>

These returns assume all dividends and capital gains distributions were
reinvested.

    The IAA Trust Growth Fund returned better than 26% over the past year. This
compares very favorably with the 18.9% return of the average growth mutual fund
and the 22.8% return of the S&P 500 index* over this same time span. Until
recently, the largest capitalization stocks have been driving overall market
performance and the Fund has benefited from its strong core of these stocks.
Additionally, as market leadership has recently shifted allowing better
performance from smaller capitalization stocks and economically sensitive
issues, the Fund's diversification in these market sectors has provided positive
results.

    By all conventional measures, today's stock market appears fully valued, if
not overvalued. In many respects, the market needs a continuation of steady
economic growth, low inflation and unemployment, and stable low interest rates
to maintain current valuations. Any event that clouds the economic outlook has
the potential to drive the market sharply lower; and individual stocks that have
fundamental disappointments can be punished severely. Increased volatility can
readily be seen in broad market indices and individual stock prices.

    Nevertheless, solid values can still be found in the market. The largest of
the large cap companies dominate measures of market valuation due to their sheer
size and weighted contribution to market indices. Smaller companies with good
growth prospects and reasonable valuation can still be found. Our strategy
continues to be one of seeking out the growth stocks that add value for our
shareholders. We will not ignore the largest companies, they drive overall
market results, but we will take all opportunities that can provide a benefit to
our shareholders.

                     IAA TRUST ASSET ALLOCATION FUND, INC.
                             INCEPTION DATE 12/7/78

The annualized total returns for the fund for the period ended June 30, 1999,
are as follows:

<TABLE>
<CAPTION>
1 YEAR  5 YEAR   10 YEAR
- ------  -------  --------
<S>     <C>      <C>
16.22%  15.69%    11.50%
</TABLE>

These returns assume all dividends and capital gains distributions were
reinvested.

    The IAA Trust Asset Allocation Fund just finished one of its best years
ever. Performance was very good on both a relative and absolute basis. For the
year, the Fund was up 16.2%. This compares very favorably to the average
flexible fund, which returned 10.5% over the same period.

    Increasing our exposure to stocks at the end of 1998 turned out to be a very
successful strategy. Since that time, the stock market has had one of its
strongest surges in history, with the S&P 500 Index* gaining about 45% off its
lows in August, 1998. Our performance was enhanced even more because we focused
on large capitalization stocks, which were the driving force behind the market's
strength. We also benefited from the great performance of a few key technology
holdings.

    Our bond position was reduced to accommodate our higher equity weighting.
The timing was excellent, as the bond market stalled over inflation fears. We
also shifted our holdings from U.S. Treasuries to corporate issues, which helped
our performance compared to some of our peers.

    The asset allocation as of June 30, 1999 was 60% stock, 36% bonds, and 4%
cash equivalents.

                      IAA TRUST TAX EXEMPT BOND FUND, INC.
                             INCEPTION DATE 12/7/78

The annualized total returns for the Fund for the period ended June 30, 1999,
are as follows:

<TABLE>
<CAPTION>
1 YEAR  5 YEARS  10 YEARS
- ------  -------  --------
<S>     <C>      <C>
2.14%    6.09%    6.06%
</TABLE>

These returns assume all dividends and capital gains distributions were
reinvested. Although the Fund's income is exempt from federal income tax, it may
be subject to state income taxation or the Federal alternative minimum tax.

    Over the past year, the IAA Trust Tax-Exempt Bond Fund changed from a
long-term to an intermediate-term municipal bond fund. The duration of the Fund
has been reduced from approximately seven years to five. We will no longer use
the Lehman Municipal Bond Index* but instead use the Lehman Seven-Year Municipal
Bond Index*.

    The Fund's one-year total return was 2.14%. This compares to the Lehman
Brothers Seven-Year Municipal Bond Index's* total return of 2.92%. The Lehman
Index* does not reflect investments in cash, the impact of any servicing,
investment management, or administrative expenses.

    The municipal market outperformed the U.S. Treasury market over the past
year. Yields on municipals declined during the second half of 1998 and though
higher in 1999, remained below their August, 1998 levels until May of this year.
At that time, the upward pressure on yields in the Treasury market began to take
a toll on the municipal market. As we go forward into the last six months of
1999, we look for municipals to continue to outperform Treasuries. Higher
interest rates make bonds attractive again to investors but not to issuers.
Should demand exceed supply, we could see better performance in the municipal
market.

                IAA TRUST TAXABLE FIXED INCOME SERIES FUND, INC.

                             MONEY MARKET SERIES**
                            INCEPTION DATE 10/26/81

    In the fall of 1998, the Federal Reserve imposed three 25-basis-point rate
cuts over a 49-day period in order to combat the effects of the global slowdown.
Reflective of reduced short-term interest rates, the IAA Trust Money Market
Series' 7-day yield decreased from 4.88% to 4.21% over the past fiscal year. The
12-month total return also decreased from 4.94% on June 30, 1998, to 4.54% on
June 30, 1999. The fiscal year ended with the global economy recovering and
attention being refocused on mounting inflationary pressures domestically. This
caused the Federal Reserve to increase short-term interest rates by 25 basis
points on June 30, 1999. Some argue that the Federal Reserve's quick action last
fall was one cut too many, and this action simply reverses the last cut. While
the Fed has openly stated a neutral policy, we believe they will continue to
keep a vigilant watch for any signs of inflation creeping into our economy.

                      SHORT-TERM GOVERNMENT BOND SERIES***
                             INCEPTION DATE 1/2/97

The annualized total returns for the Fund for the period ended June 30, 1999,
are as follows:

<TABLE>
<CAPTION>
1 YEAR  SINCE INCEPTION
- ------  ---------------
<S>     <C>
4.27%     5.18%
</TABLE>

These returns assume all dividends and capital gains distributions were
reinvested.

    Short duration bonds have outperformed long-maturity bonds the past year as
interest rates were rising. The star performers have been short mortgage and
asset-backed sectors that the Fund has been emphasizing. With higher interest
rates and a relatively flat yield curve, we are in the process of lengthening
the duration of the Fund. The majority of our purchases have been in the agency
sector. Agency bonds in today's market have attractive yield spreads versus
comparable Treasuries.

    It is entirely possible that inflation will remain low, the stock market
will cool, and the Federal Reserve will not be pressured to raise rates. Under
this scenario, the Fund would be a rewarding investment. Even if these events do
not transpire, the Fund, because of its short maturity structure, should weather
any downturns.

                            LONG-TERM BOND SERIES***
                             INCEPTION DATE 1/2/97

The annualized total returns for the Fund for the period ended June 30, 1999,
are as follows:

<TABLE>
<CAPTION>
1 YEAR  SINCE INCEPTION
- ------  ---------------
<S>     <C>
3.29%     6.38%
</TABLE>

These returns assume all dividends and capital gains distributions were
reinvested.

    Prices on most kinds of bonds have slumped this year, sending yields higher.
Bond investors are worried that the economy is growing too quickly, and that the
prospect of higher inflation might cause the Federal Reserve to unleash a string
of interest-rate increases. The yield of the bellwether 30 year Treasury bond
has jumped to 6.125% from 4.8% last fall. Rates are now at their highest levels
and prices at their lowest levels since late 1997.
<PAGE>   4

    However, there is light at the end of the tunnel. Today's rates give the
investor a very attractive real return over inflation. Picking the exact peak in
bond yields is an impossible task, but we may be close. If this is the case,
total returns on bonds for the next year could be attractive. In this higher
interest rate environment, the Fund is extending its average maturity and
increasing its holdings of Treasury securities. The average life of the Fund is
approximately 13 years and is AA quality. AA is a rating to individual bonds and
not the Fund.

                                   Sincerely,

                            [Ronald Warfield Photo]

IAA TRUST MUTUAL FUNDS -- NOTES TO FINANCIAL STATEMENTS June 30, 1999

- --------------------------------------------------------------------------------

NOTE (A) SIGNIFICANT ACCOUNTING POLICIES: The IAA Trust Mutual Funds represent
four separate funds, with one Fund containing three separate Series (referred to
herein as "Funds" or "Series"). Each of the Funds and Series has distinct
investment objectives and policies. The four Funds are as follows: IAA Trust
Growth Fund, Inc. ("Growth Fund"); IAA Trust Asset Allocation Fund, Inc. ("Asset
Allocation Fund"); IAA Trust Tax Exempt Bond Fund, Inc. ("Tax Exempt Bond
Fund"); and IAA Trust Taxable Fixed Income Series Fund, Inc. ("Taxable Fixed
Income Series Fund"), formerly known as IAA Trust Money Market Fund, Inc. The
Taxable Fixed Income Series Fund currently consists of the following three
separate investment Series: IAA Trust Money Market Series ("Money Market
Series"); IAA Trust Short-Term Government Bond Series ("Short-Term Government
Bond Series"); and IAA Trust Long-Term Bond Series ("Long-Term Bond Series").
The Short-Term Government Bond Series and the Long-Term Bond Series commenced
operations on January 2, 1997. The Funds are separately incorporated and
registered companies under the Investment Company Act of 1940 (the "Act"), as
amended, as diversified, open-ended management companies.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates. The
following is a summary of significant accounting policies consistently followed
by each Fund in the preparation of its financial statements.

    (1) SECURITY VALUATION: For the Growth Fund, the Asset Allocation Fund, the
    Tax Exempt Bond Fund, the Short-Term Government Bond Series and the
    Long-Term Bond Series, securities traded on national exchanges and
    over-the-counter securities listed in the NASDAQ National Market System are
    valued at the last reported sales price at the close of the New York Stock
    Exchange. Securities for which there have been no sales on such day are
    valued at the last reported bid price on such exchange. Over-the-counter
    securities not listed on the NASDAQ National Market System are valued at the
    mean of the current bid and asked prices. Fixed-income securities except
    short-term securities may be valued on the basis of prices provided by a
    pricing service when such prices are believed by the Advisor to reflect the
    fair market value of such securities. Short-term investments, such as those
    with a remaining maturity of 60 days or less, are valued at amortized cost,
    which approximates market value. For the Money Market Series, all securities
    are valued at amortized cost, which approximates market value. Under the
    amortized cost method, discounts and premiums are accreted and amortized
    ratably to maturity and are included in interest income.

    (2) INVESTMENT INCOME AND SECURITIES TRANSACTIONS: Dividend income is
    recorded on the ex-dividend date. Interest income is accrued daily.
    Securities transactions are accounted for on the trade date basis. Gains or
    losses on the sale of securities are determined by use of the specific
    identification method for both financial reporting and income tax purposes.

    (3) FEDERAL INCOME TAXES: The Funds have elected to be treated as "regulated
    investment companies" under Sub-chapter M of the Internal Revenue Code and
    to distribute substantially all of their net taxable income annually.
    Accordingly, no provisions for Federal income taxes have been made in the
    accompanying financial statements.

    (4) DIVIDENDS AND DISTRIBUTIONS: Dividends and distributions to shareholders
    are recorded on the ex-dividend date. Income distributions and capital gain
    distributions are determined in accordance with income tax regulations,
    which may differ from generally accepted accounting principles.

NOTE (B) DIVIDENDS FROM NET INVESTMENT INCOME AND DISTRIBUTIONS OF CAPITAL
GAINS: In the Growth Fund, net investment income from investment transactions is
declared and distributed to shareholders twice a year. The Asset Allocation
Fund, the Tax Exempt Bond Fund, the Short-Term Government Bond Series and the
Long-Term Bond Series, declare and distribute net investment income to
shareholders monthly. The Money Market Series declares dividends daily from its
net investment income, which are payable monthly. Dividends are automatically
reinvested in additional Fund shares, at the then current net asset value, for
those shareholders that have elected the reinvestment option. Net realized gains
from investment transactions, if any, of all Funds are generally distributed
twice a year.

NOTE (C) CAPITAL STOCK: At June 30, 1999, 10,000,000 shares of capital stock
were authorized for each of the Growth Fund, Asset Allocation Fund, and Tax
Exempt Bond Fund, each Fund having a par value of $1.00 per share. The
authorized capitalization of the Taxable Fixed Income Series Fund consists of
250,000,000 shares with the par value of $0.10 per share. 100,000,000 of this
Fund's

REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
OF IAA TRUST COMPANY MUTUAL FUNDS

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations, changes
in net assets, and the financial highlights present fairly, in all material
respects, the financial position of IAA Trust Company Mutual Funds (the "Funds")
(comprising, respectively, the IAA Trust Growth Fund, Inc., the IAA Trust Asset
Allocation Fund, Inc., the IAA Trust Exempt Bond Fund, Inc. and the IAA Trust
Taxable Fixed Income Series Fund, Inc., which includes the IAA Trust Money
Market Series (formerly known as the IAA Trust Money Market Fund, Inc.), the IAA
Trust Short-Term Government Bond Series and the IAA Trust Long-Term Bond Series)
at June 30, 1999, and the results of its operations, changes in its net assets,
and its financial highlights for each of the periods presented, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at June 30, 1999 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
