            LOW MINIMUM INVESTMENT    Initial investments in the Portfolios can be as low as
                                      $1,000.

            DOLLAR COST AVERAGING     Dollar Cost Averaging is a means of investing by which you
                                      invest a fixed dollar amount on a consistent basis. You
                                      invest whether the financial markets are high or low. As a
                                      result, you buy more shares when prices are low and fewer
                                      when prices are high. In this way, you can achieve a lower
                                      average cost per share.*

LETTER FROM THE CHIEF INVESTMENT OFFICER
- --------------------------------------------------------------------------------
 
To Our Shareholders:
 
I'm pleased to present the AmeriStar Mutual Fund's semiannual report for the six
months ended June 30, 1997.
 
"How Sweet It Is," exclaimed the late Jackie Gleason at the beginning of his
weekly television variety show in the 1960s. That description could be used to
characterize the fundamentals of the U.S. economy and the financial markets in
the summer of 1997. The economy's rate of growth has subsided to a moderate
level; inflation remains comparatively low; the bond market is rallying as
interest rates decline; and the stock market continues to set records.
 
Things are so good that it may be appropriate to be even more alert and well
prepared, since this is when negative surprises can have the most dramatic
impact. The investment community is happy and puzzled that, despite a seven-year
economic expansion, inflation is not yet a problem. As long as inflation
expectations remain low, the bond market should continue to provide average
returns.
 
Meanwhile, corporate profits are continuing to advance at a healthy clip; the
federal budget deficit is shrinking; and a capital gains tax cut has been signed
by the President. After peaking in mid-April, interest rates began to fall.
Between mid-April and mid-June, the stock market rose 23%, one of the sharpest
advances for a two-month period in this century. If the market holds these gains
through the end of 1997, it will mark the third consecutive year of 20% plus
gains, a feat accomplished only one other time this century.
 
The financial services, health-care and technology sectors outperformed the S&P
500 Index for the six-month period, while consumer cyclicals, basic materials
and utilities underperformed. Large-capitalization stocks continued to
outperform the small- and mid-cap universe, but by a smaller margin than in
1996. Growth stocks outperformed value stocks.
 
However, the lofty valuation of the stock market leaves no room for
disappointment on any of the major variables -- interest rates, inflation and
profits. Thus, the market is highly vulnerable to negative news. As a result, we
remain defensive in our investment strategies, taking profits in stocks that we
believe have become overvalued. For reinvestment, we are seeking out those
companies that have sound financial characteristics but, for one reason or
another, have lagged the market.
 
To give you even more investment alternatives, we have introduced three new
mutual funds during the period, the Dividend Growth Portfolio, the Limited
Duration Tennessee Tax Free Portfolio and the Limited Duration U.S. Government
Portfolio. We're very happy to report that the Dividend Growth Portfolio and the
Capital Growth Portfolio handily beat their investment benchmarks during the
period.
 
Thanks for the opportunity to help you meet your investment goals.
 
Sincerely,
 
/s/ Frederick S. Crown Jr., CFA

        Prime Money Market Portfolio            Market Portfolio
 
 INVESTMENT GOAL
 The AmeriStar money market portfolios seek to provide as high a level of
 current income as is consistent with the preservation of capital and the
 maintenance of liquidity. Each Portfolio seeks its objective by investing in:
 PRIME MONEY MARKET PORTFOLIO -- A broad range of U.S. Government, bank and
 corporate short-term money-market obligations.
 U.S. TREASURY MONEY MARKET PORTFOLIO -- U.S. Treasury securities, other
 obligations that are guaranteed as to principal and interest by the U.S.
 Government and related repurchase agreements.*
 
Q. WHAT FACTORS AFFECTED THE PERFORMANCE OF THE MONEY MARKET FUNDS?*
 
A. Mixed economic indicators and the uncertainty of if and when the Federal
Reserve Board would push interest rates higher kept short-term rates fairly
stable during much of the period. When the Fed raised rates 0.25% on March 25,
investors initially believed that the move would be just one of several. Since
the average maturities of the Funds were fairly short at the end of March, the
Funds were able to extend their maturities and quickly take advantage of the
rate increase. The Fed chose not to increase rates a second time at its May
meeting.

Q. WHAT FACTORS COULD AFFECT THE FUNDS IN THE MONTHS AHEAD?
 
A. The main factor affecting the Funds, of course, will be the direction of
interest rates. Currently, the continuing strength of the economy has not
precipitated a commensurate increase in inflation, and the Federal Reserve seems
inclined to just watch the situation for now. Any indications of inflation
pressures could cause the Federal Reserve to re-evaluate its position. Our
strategy will continue to keep maturities shorter than average, since yields on
longer maturities are not significantly higher -- and in some cases are actually
lower -- than yields on shorter maturity securities.

   Yields will vary with market conditions, and past
   performance is no guarantee of future results.
</TABLE>
 
- ---------------------------------------------------------------
 
Persistently large cash balances held by money market managers industry-wide,
combined with low issuance, continues to contribute to the low interest-rate
environment. This is especially true in the Treasury market, where a decrease in
the government's Treasury bill issuance has caused those rates to decline
sharply over the past few months. In the absence of Fed action, it is likely
that rates paid on short-term instruments will actually decline rather than
remain stable due to these supply/demand factors.
 
- ---------------
* An investment in the AmeriStar Money Market Portfolios is neither insured nor
  guaranteed by the U.S. Government. Yields will fluctuate, and there is no
  assurance that the Portfolios will be able to maintain a stable net asset
  value of $1.00 per share.

                    Capital Growth
                    Portfolio
 
===============================================================
 INVESTMENT GOAL
 The Portfolio seeks to provide investors with the potential to achieve
 long-term capital growth by investing primarily in the equity securities of
 domestic issuers whose earnings are growing faster than the economy as a
 whole. It invests primarily in large U.S. companies with market
 capitalizations of at least $500 million. This Portfolio is suitable for
 investors who are investing for the long term and are comfortable assuming the
 additional risk of investing in stocks in exchange for potentially higher
 total returns.
- ---------------------------------------------------------------
 
Q. HOW WOULD YOU ASSESS THE PORTFOLIO'S PERFORMANCE FOR THE PERIOD?
 
A. We're very pleased with our performance, which exceeded the average of growth
funds, as measured by Lipper Analytical. The AmeriStar Capital Growth
Portfolio's total return was 16.21%* for the six months ended June 30, 1997. In
comparison, the Lipper Growth Fund Index was up 15.40%, and the Standard &
Poor's 500 Index was up 20.62%. The Lipper Growth Fund Index is an index of
managed funds that is generally representative of growth stock funds. The S&P
500 is an unmanaged index that is considered to be generally representative of
the U.S. stock market as a whole.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. Growth stocks continued to do well relative to other sectors of the market.
Another positive trend was the substantial rally in the bond market. After
boosting short-term interest rates a quarter point on March 25, the Federal
Reserve Board decided against a second interest rate increase in May. As a
result, our interest-sensitive stocks in the financial services industry
outperformed other stocks that are less sensitive to interest rates. Other areas
that performed well included pharmaceutical and technology stocks.
 
Q. WHERE DO YOU SEE THE NEXT AREAS OF GROWTH?
 
A. Recently, we have added funds to our telecommunications area. Stocks such as
Lucent Technologies (2.0% of the portfolio) and BellSouth (2.3%) have performed
strongly and continue to appear very attractive.** With energy prices coming
down, we also have begun to add transportation companies. Recently, we added
Southwest Airlines (2.2%) because we like their discount strategy and strong
management.
 
Because of the continuing trend toward consolidation, we continue to emphasize
financial services. Recently, we added Wachovia Bank (2.1%), a very well-run
bank that has lagged other banks in stock price performance. The company has
made some excellent banking acquisitions in the Virginia market. We would prefer
to see banks buy other banks and not get into the brokerage industry. That type
of diversification recalls the banking industry's disastrous move into real
estate in the 1970s at the real estate market's peak.
 
Q. WHAT AREAS ARE YOU AVOIDING?
 
A. We've avoided the consumer cyclical stocks such as the retailers, as well as
basic industry companies that are susceptible to an economic slowdown. In
addition, as oil prices softened in the second quarter, we began to cut back on
energy companies. As a defensive measure, we have added another ten companies in
an effort to further diversify the portfolio.
 
Q. WHAT'S YOUR OUTLOOK?
 
A. Last December, Federal Reserve Chairman Alan Greenspan accused investors of
"irrational exuberance" in their desire to own stocks. However, we believe that
investor exuberance is quite rational. The economic environment is truly ideal.
Inflation has come down -- and we may actually be in a deflationary environment.
We have had favorable corporate profit growth in the first and second quarters.
Due to the robust economy and the tax revenues it generates, the federal budget
deficit is shrinking faster than anyone expected. In addition, the capital gains
tax rate will be cut, which is favorable for growth stocks in particular.

                    Dividend Growth
                    Portfolio
 
===============================================================================
INVESTMENT GOAL

The Portfolio seeks to provide investors with current income and capital
appreciation. This Portfolio will invest primarily in dividend-paying equity
securities of domestic issuers that are expected to provide reasonable income
and may have capital appreciation potential.  

- -------------------------------------------------------------------------------
Q. WHAT IS THE PURPOSE OF THIS NEW FUND?
 
A. Our goal is to provide above-average income first and capital appreciation
second. The types of stocks in the portfolio are generally household names that
pay a significant dividend. Examples include Bristol-Myers Squibb (2.1% of the
portfolio), Exxon (1.2%) and McGraw-Hill (1.9%).** We would like to achieve a
dividend yield in the Portfolio of one percentage point over the S&P 500 Index,
which is currently yielding 1.7%. Although the Portfolio began operations on
February 28, 1997, it was actually converted from an existing common trust fund
that had been in existence for more than ten years.
 
Q. HOW WOULD YOU ASSESS THE PORTFOLIO'S PERFORMANCE FOR THE PERIOD?
 
A. Because of some very good stock selections in the first quarter, the
portfolio's total return for the six months ended June 30, 1997 was 18.26%,*
substantially greater than the Lipper Equity Income Index, which was up 15.40%.
The Lipper Equity Income Index is an unmanaged index generally representative of
funds that invest over 60% of assets in equities.
 
Since we are trying to provide above-average equity income, we are going to have
a high percentage of energy, financial and utility shares. Energy and
particularly financial stocks were generally strong in the first half. In
addition, a stock such as McGraw-Hill (1.9%), which is in the college textbook
publishing business, is benefiting from demographic trends. Texas and
California, the two biggest markets for educational materials, are in the
process of ordering new books for students. The stock was up 32% during the
period.
 
Q. WHAT IS THE PORTFOLIO'S STRATEGY FOR ACHIEVING ABOVE-AVERAGE DIVIDEND INCOME?
 
A. In addition to searching for large-and mid-cap stocks paying above-average
dividends, we are also investing in convertible securities and real estate
investment trusts (REITs). For example, Equity Residential Properties (1.9%),
the largest apartment REIT in the country, is producing a current yield of 5.2%.
We also own a convertible bond issued by Hilton Hotels (0.9%) that offers a 3%
yield and most of the appreciation potential of Hilton's common stock. However,
we chose not to invest in the stock because it does not pay a dividend. It is
important to be very selective in purchasing convertible bonds, because there
are many convertibles in the marketplace issued by companies that are not doing
well.**
 
Q. WHAT IS YOUR STRATEGY FOR THE NEXT SIX MONTHS?
 
A. We're starting to realize some profits in the large-capitalization companies
whose prices have risen sharply. We're reinvesting those profits in sectors and
stocks that appear relatively undervalued. For example, we recently added Duke
Energy (2.0%), a North Carolina utility, which has risen just 5% this year. The
stock offers a 4% dividend yield, and we believe that the company has good
long-term prospects. Utilities are defensive when a market correction occurs.
We're also starting to emphasize more mid-cap companies that have good business
niches. An example is Johnson Controls (1.5%), a manufacturer of automobile
parts, heating, air conditioning and other climate controls. We believe that our
strategy of emphasizing dividends will help to cushion the Portfolio in the
event of a stock market sell-off later in 1997.
 
- ---------------
  * Including the 3.00% sales load, the Portfolio's return was 14.68% for the
    period.
 
    The quoted performance of the AmeriStar Dividend Growth Portfolio includes
    performance of certain collective trust fund ("Commingled") accounts advised
    by First American National Bank, for periods dating back to 12/31/86 and
    prior to the mutual fund's commencement of operations on 2/28/97, as
    adjusted to reflect the expenses associated with the mutual funds. The
    Commingled accounts were not registered with the Securities and Exchange
    Commission and, therefore, were not subject to the investment restrictions
    imposed by law on registered mutual funds. If the Commingled accounts had
    been registered, the Commingled accounts' performance may have been
    adversely affected. The performance shown reflects the deduction of fees for
    value-added services associated with a mutual fund, such as investment
    management and accounting fees. The performance also reflects reinvestment
    of all dividends and capital-gains distributions.

                    Portfolio
 
===============================================================================
 INVESTMENT GOAL
 The Portfolio seeks to provide investors with current income without assuming
 undue risk. It invests primarily in investment-grade U.S. dollar-denominated
 fixed-income securities of domestic and foreign issuers with maturities of any
 length. This Portfolio is suitable for investors seeking regular monthly
 income without undue risk to principal.
- -------------------------------------------------------------------------------
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE FIRST HALF OF 1997?
 
A. Due to a volatile interest rate environment in the first quarter, the Core
Income Portfolio produced a total return of 2.14%* for the six-months ended June
30, 1997. In comparison, the Merrill Lynch Corporate/Government Index, an
unmanaged benchmark, produced a total return of 2.79%. The Merrill Lynch
Corporate/Government Master Index is generally representative of U.S. Treasury
and Agency bonds and investment-grade corporate bonds. Total return equals yield
plus or minus the change in the Portfolio's net asset value during the period.
The total return percentage is not annualized.
 
It is also important to recognize income yield to shareholders. As of June 30,
1997, the Portfolio's 30-day SEC yield was 5.86%** at NAV, compared to 5.30% at
the end of 1996. The yield percentage is annualized.
 
Q. WHAT FACTORS AFFECTED THE PORTFOLIO'S PERFORMANCE?
 
A. Two factors affected the Portfolio: the stronger-than-expected economy in the
first quarter and the volatile interest rate environment. In the first quarter,
the Gross Domestic Product grew a sizzling 5.9%. In response, the Federal
Reserve Board increased short-term interest rates from 5.25% to 5.50%.
Meanwhile, the 30-year U.S. Treasury bond peaked at 7.17% before easing to 6.78%
at June 30, 1997. Bond prices move inversely to interest rates.
 
The reason for the interest rate volatility is that since World War II, economic
expansions have been followed by higher inflation, so many bond investors
thought rates would move higher. Yet, we're in the seventh year of an expansion,
and inflation is actually coming down. Another thing that is unusual is that the
Federal Reserve Board typically raises interest rates more than once. Investors
were expecting the Fed to boost rates at least one more time during the second
quarter, but rates pushed lower after the Fed made no changes.
 
Q. WHAT WAS YOUR STRATEGY DURING THE PERIOD?
 
A. In the corporate portfolio, we were able to add yield by purchasing bonds
issued by IBM (1.7% of the portfolio) and Reliance Electric (2.0%). In one
instance, we had a choice between IBM and Eli Lilly; we sold Lilly and bought
IBM because it was yielding 0.60% over Treasuries (whereas Eli Lilly was
yielding only 0.35% over Treasuries). And yet, both companies have fairly
similar credit ratings.***
 
We have avoided the tobacco bonds for a long time for obvious reasons. Even with
the recent agreement between the states and the tobacco companies, we don't
think we are adequately compensated for the risk of owning them. The details of
the agreement are still too uncertain.
 
Q. WHAT IS YOUR OUTLOOK?
 
A. From a credit standpoint, the financial and industrial sectors are doing very
well. Many more bonds have received credit upgrades than downgrades. A lot of
these companies have issued stock and have bolstered the equity on their balance
sheets.
 
Nevertheless, the financial markets remain event driven and volatile. A negative
economic report or a sudden upward spike in inflation could again prompt the Fed
to increase interest rates as they did in March. Even the perception of a
possible move by the Fed would likely be enough to send yields toward the upper
end of our expected trading range. However, barring a strong resurgence in the
economy or in the rate of inflation, we feel that the previous high of 7.17% for
the 30-year Treasury bond will hold.

                    Limited Duration
                    Income Portfolio
 
===============================================================================
 INVESTMENT GOAL
 The Portfolio seeks to provide investors with current income without assuming
 undue risk. It invests primarily in investment-grade, U.S. dollar-denominated
 fixed-income securities of domestic and foreign issuers that generally have a
 duration of under four years. This Portfolio is suitable for investors seeking
 regular monthly income without undue risk to principal.
- -------------------------------------------------------------------------------
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE FIRST HALF OF 1997?
 
A. Due to rising interest rates in the first quarter, the Limited Duration
Income Portfolio produced a total return of 2.6% for the six-months ended June
30, 1997.* In comparison, the Merrill Lynch 1-5 Year Corporate/Government Index,
an unmanaged benchmark, produced a total return of 2.9%. The index is a broad
performance measure of bonds with maturities in the one-to-five-year range.
Total return equals yield plus or minus the change in the Portfolio's net asset
value during the period. The total return percentage is not annualized.
 
It is also important to recognize income yield to shareholders. As of June 30,
1997, the Portfolio's 30-day SEC yield was 5.65%** at NAV compared to 5.22% as
of December 31, 1996. The yield percentage is annualized.
 
Q. WHAT FACTORS AFFECTED THE PORTFOLIO'S PERFORMANCE?
 
A. Two factors affected the Portfolio: the stronger-than-expected economy in the
first quarter and the volatile interest rate environment. In the first quarter,
the Gross Domestic Product grew a sizzling 5.9%. In response, the Federal
Reserve Board boosted short-term interest rates from 5.25% to 5.50%. Meanwhile,
the five-year U.S. Treasury bond moved from a yield of 6.21% on December 31,
1996, to 6.86% on April 14, 1997. Because the economy slowed in the second
quarter, and the Fed decided not to raise short-term interest rates a second
time, and the five-year U.S. Treasury bond yield eased to 6.14% by June 30,
1997. Bond prices move inversely to interest rates.
 
The reason for the interest-rate volatility is that since World War II, economic
expansions have been followed by higher inflation, so many investors thought
that rates would move higher. Yet, we're in the seventh year of an expansion,
and inflation is actually coming down. Another thing that is unusual is that the
Federal Reserve Board typically raises interest rates more than once. Investors
were expecting the Fed to boost rates at least one more time during the second
quarter, but rates pushed lower after the Fed made no changes.
 
Q. WHAT STRATEGIES HAVE YOU EMPLOYED?
 
A. In an effort to boost the Portfolio's yield, we have shifted some money away
from U.S. Government bonds and into high-grade corporate bonds. Some of the more
attractive names are in banking and finance. For instance, we recently sold some
U.S. Treasury bonds to purchase Bankers Trust bonds (1.45% of the portfolio) due
in 2001. In doing so, we picked up nearly one percentage point in yield.***
 
Q. HOW HAS THE SHRINKING FEDERAL BUDGET DEFICIT AFFECTED THE MARKET?
 
A. Consider that foreign buyers purchased $268 billion worth of U.S. Treasury
securities in the first quarter, during which time the U.S. Government issued
only $72 billion in new bonds. Interest rates are falling because the national
debt is growing less rapidly and foreigners are coming in and soaking up what
debt there is. The Japanese will continue to buy our bonds as long as their
ten-year treasury pays only 2.5% while ours pays more than 6%.
 
Q. WHAT IS YOUR OUTLOOK?
 
A. It depends on the strength of the economy. The bond market performs well as
long as GDP growth stays in the 2% to 2.5% range. But if we start growing at 3%
to 4%, particularly since the economy is at full employment already, then
interest rates will likely rise again.

                    U.S. Government
                    Portfolio
 
===============================================================================
 INVESTMENT GOAL
 The Portfolio seeks to provide investors with high current income without
 assuming undue risk. This Portfolio will invest primarily in a portfolio of
 U.S. Government securities that, under normal market conditions, has a
 duration that approximates that of the Merrill Lynch Government 1- to 5-Year
 Bond Index.
- -------------------------------------------------------------------------------
 
Q. WHAT IS THE PURPOSE OF THIS NEW FUND?
 
A. This is an opportunity to invest in a relatively short-term fund of U.S.
Government, agency and selected mortgage-backed securities. Without corporate
securities, the Portfolio offers higher credit quality but somewhat lower yield.
The average maturity of the Portfolio is about three years.
 
Although this is a new mutual fund, it is not a new portfolio. The Limited
Duration U.S. Government Portfolio began operations on February 28, 1997,
through a transfer of assets from a trust fund managed by First American
National Bank, which used substantially the same investment objective and
methods.
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE FIRST HALF OF 1997?
 
A. The Limited Duration U.S. Government Portfolio produced a total return of
2.3%.* In comparison, the Merrill Lynch 1-5 Year Government Bond Index, an
unmanaged benchmark, produced a total return of 2.8%. The index is a broad
performance measure of government bonds with maturities in the one-to-five-year
range. Total return equals yield plus or minus the change in the Portfolio's net
asset value during the period. The total return percentage is not annualized.
 
It is also important to recognize income yield to shareholders. As of June 30,
1997, the Portfolio's 30-day SEC yield at NAV was 5.25%.** The yield percentage
is annualized.
 
Q. WHAT FACTORS AFFECTED THE PORTFOLIO'S PERFORMANCE?
 
A. Two factors affected the Portfolio: the stronger-than-expected economy in the
first quarter and the volatile interest rate environment. In the first quarter,
the Gross Domestic Product grew a sizzling 5.9%. In response, the Federal
Reserve Board boosted short-term interest rates from 5.25% to 5.50%. Meanwhile,
the five-year U.S. Treasury bond moved from a yield of 6.21% on December 31,
1996, to 6.86% on April 14 and back down to 6.14% on June 30, 1997. Bond prices
move inversely to interest rates.
 
Q. WHAT IS YOUR STRATEGY?
 
A. Because interest rates fell in the second quarter, one of our goals has been
to find ways to increase the Portfolio's yield. Agency securities and bonds that
are callable typically offer higher yields. In the second quarter, interest
rates have been falling. As a result, we de-emphasized mortgage-backed
securities -- particularly those with higher coupons -- because they have a
tendency to be refinanced when rates fall.***
 
Q. WHAT IS YOUR OUTLOOK?
 
A. There are four developments that bode well for the bond market and lower
interest rates. One is the globalization of the economy. Investments should not
rely solely upon domestic capacity, whether it's labor, materials or
manufacturing capacity. That has had a great disinflationary impact on our
markets. The second is the revolutionary impact of computer technology on cost
efficiencies. Thirdly, the change in demographics is very real. With the aging
population, people are saving and investing huge amounts of money. Finally,
there has been a major change in inflationary psychology. Fifteen years ago,
people thought that you better buy now or the price is going up. Now, you've got
the reverse. Why buy now when the price may be lower tomorrow? This is why we're
in the seventh year of an economic recovery and the consumer price index is
falling.

    operations of 2/28/97, as adjusted to reflect the expenses associated with
    the mutual funds. The Commingled accounts were not registered with the
    Securities and Exchange Commission and, therefore, were not subject to the
    investment restrictions imposed by law on registered mutual funds. If the

    the deduction of fees for value-added services associated with a mutual

                    Tax Exempt
                    Bond Portfolio
 
===============================================================================
 INVESTMENT GOAL
 The Portfolio seeks to provide investors with current income exempt from
 federal and Tennessee State income taxes without assuming undue risk. The
 Portfolio invests primarily in investment-grade Tennessee municipal
 obligations and is suitable for Tennessee residents seeking monthly interest
 income exempt from both federal and Tennessee personal income taxes.*** The
 Portfolio affords greater diversification and liquidity than most investors
 would achieve by purchasing municipal securities directly.
- -------------------------------------------------------------------------------
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE FIRST HALF OF 1997?
 
A. The Portfolio produced a total return of 1.57%* for the six months ended June
30, 1997. In comparison, the Portfolio's unmanaged benchmark, the Lehman
Brothers Municipal 10-Year Index, produced a total return of 3.27%. The index is
a broad performance measure of municipal bonds with intermediate-term
maturities. Total return equals yield plus or minus the change in the
Portfolio's net asset value during the period. The total return percentage is
not annualized.
 
It is also important to recognize income yield to shareholders. As of June 30,
1997, the Portfolio's 30-day SEC yield at NAV was 4.19%.** For investors in the
36% federal income tax bracket, that is equivalent to a taxable yield of
6.55%.*** The yield percentage is annualized.
 
Q. WHAT FACTORS AFFECTED THE PORTFOLIO'S PERFORMANCE?
 
A. The municipal bond market continues to be volatile, reacting very strongly to
any perceived shift in the economy. As a result, the Portfolio's NAV fluctuated
significantly during the period.
 
The municipal market did not offer much additional yield for longer maturities
or lower credit quality. Beyond 15-year maturities, municipal bond yields were
relatively flat out to 30 years. In addition, we didn't believe we would be
adequately compensated for buying bonds with credit ratings below A.
 
Another factor exerting downward pressure on yields was the lack of supply of
bonds. In Tennessee, there has been a 30% decline over the last year in the
supply of municipal bond paper. Many municipalities are at their legislative
borrowing limit, without going back to the voters to request an increase. In
addition, many bonds issued prior to the Tax Reform Act of 1986 with ten year
call provisions were finally called out of the marketplace.
 
Q. WHAT TYPES OF BONDS HAVE YOU PURCHASED RECENTLY?
 
A. We are geared toward the conservative investor looking for stability of
principal and income, not stretching for yield. As a result, our strategy has
been to match our benchmark of ten years and stick with the high-quality general
obligation and essential revenue bonds. For instance, we recently purchased Knox
County 5% bonds maturing in 2015. Although the bonds are callable, the bonds
will likely trade to the longer maturity date unless interest rates fall
dramatically. In a period of falling interest rates, bonds with longer
maturities appreciate the most. Another recent purchase was Shelby County for
Methodist Hospitals 6.25% due 2008. The bonds are attractive because they have a
high coupon and are not callable. In addition, if interest rates rise, the high
coupon cushions the bond's price decline.
 
Q. WHAT IS YOUR OUTLOOK?
 
A. The market was strong in late June and early July and is probably due for a
moderate correction. However, as unemployment remains low and inflation
continues at desirable levels, we remain positive on the municipal bond market
over the long term.

                    Portfolio
 
===============================================================================
 INVESTMENT GOAL
 The Portfolio seeks to provide investors with current income exempt from
 Federal and Tennessee income taxes without assuming undue risk. This Portfolio
 will invest primarily in a portfolio of investment grade Tennessee Municipal
 Obligations that, under normal market conditions, has a duration of under five
 years and an effective average portfolio maturity ranging between three and
 five years.
 
- -------------------------------------------------------------------------------
Q. WHAT IS THE PURPOSE OF THIS NEW FUND?
 
A. The Portfolio is designed to earn a higher rate of return than a tax-free
money market fund without much fluctuation in net asset values. We accomplish
this by investing in high-quality tax-exempt securities with an average maturity
of five years or less.
 
Although this is a new mutual fund, it is not a new portfolio. The Limited
Duration Tennessee Tax Free Portfolio began operations on February 28, 1997,
through a transfer of assets from certain trust fund accounts managed by First
American National Bank, using substantially the same investment objective and
methods.
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE FIRST HALF OF 1997?
 
A. The Portfolio produced a total return of 1.71%* for the six months ended June
30, 1997. In comparison, the Portfolio's unmanaged benchmark, the Lehman
Brothers Municipal 1-5 Year Index, produced a total return of 2.42%. The index
is a broad performance measure of municipal bonds with short-term maturities.
Total return equals yield plus or minus the change in the Portfolio's net asset
value during the period. The total return percentage is not annualized.
 
It is also important to recognize income yield to shareholders. As of June 30,
1997, the Portfolio's 30-day SEC yield at NAV was 3.77%**. For investors in the
36% federal income tax bracket, that is equivalent to a taxable yield of
5.89%.*** The yield percentage is annualized.
 
Q. WHAT FACTORS AFFECTED THE PORTFOLIO'S PERFORMANCE?
 
A. On the plus side, the relationship between yields on Tennessee tax-exempts
and U.S. Treasuries are quite favorable on maturities up to five years. However,
it was difficult to obtain higher yields than that offered on the highest
quality bonds. Since the market did not compensate us for taking additional
credit risk, we focused on higher credit quality issues.
 
Another factor exerting downward pressure on yields was the lack of supply of
bonds. In Tennessee, there has been a 30% decline over the last year in the
supply of municipal bonds. Many municipalities are at their legislative
borrowing limit, without going back to the voters to request an increase. In
addition, many bonds issued prior to the Tax Reform Act of 1986 with 10-year
call provisions were finally called out of the marketplace.
 
Q. WHAT TYPES OF BONDS HAVE YOU PURCHASED RECENTLY?
 
A. One recent purchase was Johnson City, Tennessee, 6.75% due 2016 but
pre-refunded to 2002. A pre-refunding is a procedure in which a bond issuer
issues a second bond when rates are lower to pay off the first bond on a
particular date. The proceeds from the second bond are safely invested, usually
in U.S. Treasuries, timed to mature at the pre-refunded date. Because of the
pre-refunding, the bonds are rated AAA.
 
Q. WHAT IS YOUR OUTLOOK?
 
A. The market was strong in late June and early July and is probably due for a
moderate correction. However, as unemployment remains low and inflation
continues at desirable levels, I'm positive on the municipal bond market over
the long term.

THE INFINITY MUTUAL FUNDS, INC.
AMERISTAR FUNDS
- --------------------------------------------------------------------------------
 
NOTES TO FINANCIAL STATEMENTS
JUNE 30, 1997 (UNAUDITED)
- --------------------------------------------------------------------------------
 
NOTE 1 -- GENERAL
 
     The Infinity Mutual Funds, Inc. (the "Fund") was organized as a Maryland
corporation on March 6, 1990 and is registered under the Investment Company Act
of 1940, as amended (the "Act"), as an open-end, management investment company.
The Fund operates as a series company currently comprising twelve portfolios.
The accompanying financial statements and notes relate to the AmeriStar Prime
Money Market Portfolio, the AmeriStar U.S. Treasury Money Market Portfolio, the
AmeriStar Capital Growth Portfolio, the AmeriStar Dividend Growth Portfolio, the
AmeriStar Core Income Portfolio, the AmeriStar Limited Duration Income
Portfolio, the AmeriStar Limited Duration U.S. Government Portfolio, the
AmeriStar Tennessee Tax Exempt Bond Portfolio, and the AmeriStar Limited
Duration Tennessee Tax Free Portfolio (together the "Portfolios").
 
     The Prime Money Market Portfolio and U.S. Treasury Money Market Portfolio
both seek to provide investors with as high a level of current income as is
consistent with the preservation of capital and the maintenance of liquidity.
The Prime Money Market Portfolio invests in short-term money market instruments
consisting of securities issued or guaranteed by the U.S. Government or its
agencies or instrumentalities. The U.S. Treasury Money Market Portfolio invests
only in U.S. Treasury securities and in other securities guaranteed as the
principal and interest by the U.S. Government. The Capital Growth Portfolio
seeks to provide investors with capital growth by investing primarily in the
equity securities of domestic issuers. The Dividend Growth Portfolio seeks to
provide investors with current income and capital appreciation. This Portfolio
will invest primarily in dividend-paying equity securities of domestic issuers
which are expected to provide reasonable income and may have capital
appreciation potential. The Core Income Portfolio seeks to provide investors
with current income without assuming undue risk. This Portfolio will invest
primarily in investment grade, U.S. dollar denominated fixed-income securities
of domestic and foreign issuers. Under normal market conditions, the Core Income
Portfolio will invest in a portfolio of securities, except when maintaining a
temporary defensive position, that has an effective duration of 50% to 150% of
that of the Merrill Lynch Corporate Government Master Index. The Limited
Duration Income Portfolio's investment objective is to provide investors with
current income without assuming undue risk. This Portfolio will invest primarily
in investment grade, U.S. dollar denominated fixed-income securities of domestic
and foreign issuers. Under normal market conditions, the
Limited Duration Income Portfolio will invest in a portfolio of securities that
has a duration of under four years. The Limited Duration U.S. Government
Portfolio seeks to provide investors with high current income without assuming
undue risk. This Portfolio will invest primarily in a portfolio of U.S.
Government securities that, under normal market conditions, has an effective
duration that approximates that of the Merrill Lynch Government 1 to 5 Year Bond
Index. The Tennessee Tax Exempt Bond Portfolio's investment objective is to
provide investors with current income exempt from federal and Tennessee income
taxes without assuming undue risk. This Portfolio will invest primarily in
investment grade Tennessee Municipal Obligations without regard to maturity. The
Limited Duration Tennessee Tax Free Portfolio seeks to provide investors with
current income exempt from Federal and Tennessee income taxes without assuming
undue risk. This Portfolio will invest primarily in a portfolio of investment
grade Tennessee Municipal Obligations that, under normal market conditions, has
a duration of under five years and an effective average portfolio maturity
ranging between three and five years.
 
     The Portfolios are authorized to issue two classes of shares as follows:
Investor Shares and Trust Shares. Investor Shares and Trust Shares are
substantially the same, except that Investor Shares bear the fees that are
payable under the plans adopted by the Fund's Board of Directors. Under the
shareholder services plan (the "Shareholder Service Plan") for the Prime Money
Market Portfolio and U.S. Treasury Money Market Portfolio (the "Money Market
Portfolios"), fees are payable at an annual rate of 0.25% of each Money Market
Portfolio's average daily net assets represented by Investor Shares. Under the
plan adopted pursuant to Rule 12b-1 under the Act (the "Distribution Plan"), the
Capital Growth Portfolio, the Dividend Growth Portfolio, the Core Income
Portfolio, the Limited Duration Income Portfolio, the Limited Duration U.S.
Government Portfolio, Tennessee Tax Exempt Bond Portfolio and the Limited
Duration Tennessee Tax Free Portfolio (the "Variable Net Asset Value
Portfolios") pay fees at an annual rate of 0.25% of each Variable Net Asset
Value Portfolio's average daily net assets represented by Investor Shares. As of
June 30, 1997, the Variable Net Asset Value Portfolios only offer Investor
Shares.
 
     At June 30, 1997, there were 2.0 billion shares of the Money Markets
Portfolios' $0.001 par value common stock authorized, of which each Portfolio's
shares are classified into Investor Shares (500 million shares authorized per
Portfolio)

and Trust Shares (500 million shares authorized per Portfolio). There were 3.5
billion shares of the Variable Net Asset Value Portfolios' $0.001 par value
common stock authorized, of which each Portfolio's shares are classified into
Investor Shares (250 million shares authorized per Portfolio) and Trust Shares
(250 million shares authorized per Portfolio).
 
NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES
 
     The following is a summary of significant accounting policies followed by
the Portfolios in preparation of their financial statements. The policies are in
conformity with generally accepted accounting principles. The preparation of
financial statements 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 income and expenses for the
period. Actual results could differ from those estimates.
 
A)  Security Valuation:
 
     The Money Market Portfolios' securities are valued at amortized cost, which
approximates market value. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost. In addition, the Money Market Portfolios may not a) purchase
any instrument with a remaining maturity greater than 397 days unless such
investment is subject to a demand feature, or b) maintain a dollar-weighted
average portfolio maturity which exceeds 90 days.
 
     The Variable Net Asset Value Portfolios' investments are valued each
business day using available market quotations or at fair value as determined by
one or more independent pricing services (collectively, the "Service") approved
by the Board of Directors. The Service may use available market quotations,
employ electronic data processing techniques and/or a matrix system to determine
valuations. Restricted securities and securities for which market quotations are
not readily available, if any, are valued at fair value using methods approved
by the Board of Directors. Debt securities with remaining maturities of 60 days
or less are normally valued at amortized cost, which approximates market value.
The amortized cost method involves valuing a security at its cost on the date of
purchase or, in the case of securities purchased more than 60 days to maturity,
at their market value each day until the 61st day prior to maturity, and there
after assuming a constant amortization to maturity of the difference between the
principal amount due at maturity and such valuation.
 
B)  Security Transactions and Investment Income:
 
     Security transactions are recorded on trade date. Realized gains and losses
from sales of investments are calculated on the identified cost basis. Interest
income, including accretion of discount and amortization of premium on
investments, is accrued daily. Dividend income is recorded on the ex-dividend
date.
 
C)  Repurchase Agreements:
 
     The Portfolios' custodian and other banks acting in a sub-custodian
capacity take possession of the collateral pledged for investments in repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default on the obligation to repurchase, the
Portfolios have the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings.
 
D)  Expenses:
 
     The Portfolios incurred certain costs in connection with their
organization. These costs were deferred and are being amortized on a
straight-line basis over five years from their commencement of operations. The
Fund accounts separately for the assets, liabilities and operations of each
Portfolio. Direct expenses of a Portfolio are charged to that Portfolio while
general Fund expenses are allocated among the Fund's respective portfolios based
on the relative net assets of each Portfolio. At June 30, 1997, deferred
organization costs were $23,045, $24,160 $9,069, $5,959, $2,981, $21,692,
$2,261, $21,599 and $2,586 for the Prime Money Market Portfolio, the U.S.
Treasury Money Market Portfolio, the Capital Growth Portfolio, the Dividend
Growth Portfolio, the Core Income Portfolio, the Limited Duration Income
Portfolio, the Limited Duration U.S. Government Portfolio, the Tennessee Tax
Exempt Bond Portfolio and the Limited Duration Tennessee Tax Free Portfolio,
respectively.
 
E)  Federal Income Taxes:
 
     For federal income tax purposes, each Portfolio is treated as a separate
entity for the purpose of determining its qualification as a regulated
investment company under the Internal Revenue Code (the "Code"). It is the
policy of each Portfolio to meet the requirements of the Code applicable to
regulated investment companies, including the requirement

that they distribute substantially all of their income to shareholders.
Therefore, no federal income tax provision is required.
 
     At December 31, 1996, capital loss carryovers are available to offset
future net realized gains on securities transactions to the extent provided for
in the Code. Such capital loss carryover are detailed as follows:

</TABLE>
 
F)  Dividends and Distributions to Shareholders:
 
     Dividends are declared daily to shareholders of record at the close of
business on the day of declaration and are paid monthly for the Prime Money
Market Portfolio, U.S. Treasury Money Market Portfolio, Core Income Portfolio,
Limited Duration Income Portfolio, Limited Duration U.S. Government Portfolio,
Tennessee Tax Exempt Bond Portfolio and the Limited Duration Tennessee Tax Free
Portfolio. Dividends are declared and paid quarterly for the Capital Growth
Portfolio. Dividends are declared and paid monthly for the Dividend Growth
Portfolio. For all Portfolios, distributions of net realized gains, if any, will
be paid at least annually. Dividends and distributions are recorded on the
exdividend date. Distributions from net investment income and from net realized
gains are determined in accordance with income tax regulations which may differ
from generally accepted accounting principles. Timing differences relating to
shareholder distributions have been reclassified to paid-in-capital. These
differences are primarily due to deferrals of certain losses and expiring
capital loss carryovers.
 
G)  Other:
 
     Each Portfolio maintains a cash balance with its custodian and receives a
reduction of its custody fees for the amounts of interest earned on such
uninvested cash balances. For financial reporting purposes for the six months
ended June 30, 1997, there were no reductions in custodian fees and expenses
paid by third parties. There was no effect on net investment income. Each
Portfolio could have invested such cash amounts, if any, in an income producing
asset if it had not agreed to a reduction of fees and expenses under the expense
offset arrangement with its custodian.
