PROFESSIONAL INVESTMENT       The investment managers at First American National Bank are experienced 
MANAGEMENT                    investment professionals  who oversee the investments in each mutual fund.

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

DEDICATED CUSTOMER            Account information is available from helpful representatives.
SERVICE                       Just call 1-800-852-0045.

AUTOMATIC INVESTMENTS         Investments can be made once or twice a month with automatic transfers
                              from your checking account to your Fund account.

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.*

AUTOMATIC WITHDRAWALS         Automatic withdrawals from your Fund account can be made and credited

                              additional shares of a Fund.

DAILY REDEMPTIONS             Shares are redeemable each business day (at the net asset value per
                              share, which may be worth more or less than your original cost,
                              next determined after receipt of your redemption request) by mail,
                              telephone or bank wire.

 *Dollar Cost Averaging does not assure a profit and does not protect against 
  loss in declining markets. You should consider your financial ability to
  continue your investment program during periods of extreme share price
  fluctuations.
**Exchange privileges may be modified or discontinued by the Funds at any time.
  Upon redemption, shares may be worth more or less than their original cost.

LETTER FROM THE CHIEF INVESTMENT OFFICER
- --------------------------------------------------------------------------------
 
To Our Shareholders:
 
I am pleased to send you the ISG Funds' annual report for the 12 months ended
December 31, 1998, a truly historic year for the markets and our fund families.
 
The most notable event, among many of significant happenings, was the merger
between our AmeriStar Portfolios and DG Investor Series, creating the ISG Funds
on December 14, 1998. With the reorganization complete, we now manage more than
$2.8 billion in mutual fund assets.
 
Aside from giving us a considerably larger presence in the mutual fund industry,
the consolidation enables us to offer you 19 separate mutual funds--including
five exceptionally diversified "strategic portfolios" that cut across the entire
risk/reward spectrum--with which to build your portfolio. The merger between two
experienced investment advisers also has enhanced our management expertise and
research capabilities. Also, we anticipate that operating efficiencies resulting
from the merger will lead to lower administration costs and will improve the
service we provide to you, our shareholders.
 
Finally, amidst all the organizational changes that have taken place, I
certainly do not want to overlook the outstanding performance turned in by many
of our funds. Three of our stock funds--the Large-Cap Equity Fund, the Capital
Growth Fund and the Equity Income Fund--surpassed their benchmarks, as did our
Government Income Fund. The Large-Cap Equity Fund further enjoyed the
distinction of being awarded five stars, the highest possible rating, from
Morningstar, for the three- and five-year periods ended December 31, 1998.
Morningstar is an independent rating agency recognized for its risk-adjusted
performance ratings.(1)
 
STOCKS DEFIED THE LAW OF GRAVITY
 
The Dow Jones Industrial Average added 18.15%; the Standard & Poor's 500 Stock
Index(2) rose 28.74%; and the Nasdaq Composite Index(3) posted a blistering
39.63% gain. Among the major equity averages, only the Russell 2000 Stock
Index(4) lost ground, falling 2.6% for the year. But such eye-catching results
did not come without profound anxiety. The first half of the year proceeded
smoothly enough, with large-cap stocks garnering much of the attention and
attracting the lion's share of fresh capital into the market. Although
continuing concerns about the crises still swirling throughout Asia began to
chip away at investors' confidence, the Dow managed to set a new high in
mid-July. But when the full glare of summer arrived, it brought along a double
dose of trouble. First, Russia's economy imploded, with Yeltsin's government
devaluing the ruble and defaulting on $40 billion of debt, most of it held by
Western banks. Then the international credit crunch that followed sparked a new
crisis: the near-collapse of Long-Term Capital Management, a highly leverage
hedge fund with billions of dollars of paper losses in its portfolio. The
possibility that the hedge fund's troubles could damage the world's fixed-income
markets so rattled investors that the Federal Reserve Board (Fed) took the
remarkable step of engineering a bailout.
 
It did not help matters that the Clinton Administration was embroiled in
scandal. The gloom was thick in just about every market in the world, and most
investments lost considerable value--except for U.S. Treasury bonds, whose
quality attracted a flood of cash. As stocks hit bottom in August, the Dow and
the S&P 500 were down nearly 20% from their earlier peaks, and the Russell 2000
had lost 36% from its high.
 
But then the stock market, as it has done so many times in the last 15 years,
reversed course, dug itself out of its hole and proceeded to set new highs.
Aided in no small measure by the Federal Reserve's decision to cut interest
rates not once, but three times in four months, stocks ended the year on a
cheery note. And as I write this letter in the middle of January, the market has
continued its upward move, with the tech-laden Nasdaq sector surging into record
territory.

(1) Morningstar proprietary ratings reflect risk-adjusted performance through
    12/31/98. The ratings are subject to change every month. Past performance is
    no guarantee of future results. Morningstar ratings are calculated from a
    fund's three-, five- and ten-year returns (with fee adjustments) in excess
    of 90-day Treasury Bill returns, and a risk factor that reflects fund
    performance below 90-day Treasury bill returns. The Fund received 5 stars
    for the three-and-five year periods. It was rated among 2,802 and 1,702
    domestic equity funds for the three- and five-year periods, respectively.
    Ten percent of the funds in a rating category receive 5 stars; 22.5% receive
    4 stars; 35% receive 3 stars; 22.5% receive 2 stars; and 10% receive 1 star.
(2) The Standard & Poor's 500 Stock Index is an unmanaged index generally
    representative of the stock market as a whole. The index does not reflect
    expenses associated with a mutual fund, such as investment management and
    fund accounting fees. The Fund's performance reflects the deduction of fees
    for these value-added services.
(3) The Nasdaq Composite Index is a market capitalization price only index that
    tracks the performance of domestic common stocks traded on the regular
    Nasdaq market as well as National Market System traded foreign common stocks
    and American Depository Receipts.
(4) The Russell 2000 Stock Index is an unmanaged index generally representative
    of the performance of small-capitalization stocks. The index is unmanaged
    and does not reflect the deduction of expenses associated with a mutual
    fund, such as investment management and fund accounting fees. The Fund's
    performance reflects the deduction of fees for these value-added services.

LETTER FROM THE CHIEF INVESTMENT OFFICER -- (continued)
- --------------------------------------------------------------------------------
 
BONDS OFFERED A WELCOME REFUGE
 
There were times this year when, to hold a portfolio of bonds--especially
long-term Treasuries--was to feel like a winner. Throughout 1998, declining
interest rates and low inflation provided fixed-income investors with
historically handsome returns, on an inflation-adjusted basis. And when stock
markets around the world began to fall apart, the stability and interest-bearing
benefits of bonds were never more apparent.
 
When all was said and done, both long-term and short-term interest rates fell
significantly, which is always good news for bondholders. Fixed-income
securities may not always look as "attractive" as stocks, but their value as an
effective diversification tool continues to be proven again and again.
 
THE YEAR AHEAD IS FULL OF "INSURMOUNTABLE OPPORTUNITIES"
 
So what now? In 1999, will stocks rise yet again, continuing to redefine
time-honored concepts of fundamental valuation analysis? Or will they sink
beneath the weight of declining corporate earnings, political unrest and a
financial maelstrom that seems to have leaped across the oceans, from Asia and
Russia to Latin America? We would not be surprised to find it tougher to make
money over the next 12 months.
 
At the same time, we feel it would be foolish to be overly cautious;
indiscriminate caution has not been rewarded in recent years. Also, our
valuation model is fairly neutral, meaning we feel no panic about the coming
months. Despite the fact that many large-cap growth stocks are valued at levels
we suspect may be insupportable in the long run, we continue to find attractive
buying opportunities. And we are still positive about many factors that are
positively impacting financial assets, including a steady flow of cash into
stocks and bonds.
 
In the words of that sporting sage, Yogi Berra, "we are faced with
insurmountable opportunities." Risk is part of the landscape. So is the chance
to achieve a stable and secure future, through prudent investments in stocks and
bonds. That is our mission, and our responsibility to you, our shareholders.
 
We thank you for your support.
 
Sincerely,
 
/s/ Frederick S. Crown Jr.

 INVESTMENT GOAL
 The ISG money market funds seek to provide as high a level of current income
 as is consistent with the preservation of capital and the maintenance of
 liquidity. Each fund seeks its objective by investing in:
 PRIME MONEY MARKET FUND -- A broad range of U.S. Government, bank and
 corporate short-term, money market obligations.
 U.S. TREASURY MONEY MARKET FUND -- U.S. Treasury securities and 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. Actions taken by the Federal Reserve were the driving force behind the
gradual decline in yields among all money market funds. For quite some time, the
Fed had kept the fed funds rate (the rate banks charge one another for overnight
loans) artificially high. As late as last August, the rate was 5.50%, which kept
debt instruments on the short end of the yield curve--where our Funds operate -
in a fairly tight range, despite significant volatility among longer-term notes
and bonds.
 
Then, beginning in September, the Fed initiated a concerted effort to ease
credit, and lowered the fed funds rate three times, down to its present level of
4.75%. Consequently, yields declined on the short-term paper we favor.
 
As of December 31, 1998, the average maturity of the Prime Money Market Fund was
24 days; for the U.S. Treasury Money Market Fund, it was 55 days.
 
Q. WHAT IS YOUR OUTLOOK FOR THE NEXT 12 MONTHS?
 
A. We believe the Fed will be very cautious when it comes to lowering short-term
rates further. The U.S. economy is still strong, and easier credit could pump
too much cash into the monetary system, sparking inflation. As always, we will
continue to pursue the highest possible yields consistent with relative safety
of principal.

investment at $1.00 per share, it is possible to lose money by investing in the
Fund.

- ---------------------------------------------------------------
 INVESTMENT GOAL
 The Fund seeks to provide investors with high current income without assuming
 undue risk. The Fund 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 1-5-Year Government Bond Index. This
 Fund is suitable for investors seeking regular monthly income without undue
 risk to principal.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING 1998?
 
A. Despite some volatility in the market throughout the year, the Fund delivered
solid returns. For the 12 months ended December 31, 1998, the Fund produced a
total return of 6.69% (Class A shares at NAV).(1) In comparison, the Merrill
Lynch 1-5-Year Government Bond Index, produced a total return of 7.67%.
 
It is also important to recognize income yield to shareholders. As of December
31, 1998, the Fund's 30-day SEC yield was 4.32% (Class A shares at NAV),
compared to 5.46% at the end of 1997. The yield percentages are annualized. We
achieved our objectives while maintaining an average credit quality of AAA (as
rated by Standard & Poor's). As of December 31, 1998, the Fund's average
maturity was 2.6 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. The two most important factors were our maturity structure and the
international crises that afflicted Russia, Asia and South America.
 
With the Fund having a maturity structure longer than our benchmark, the Merrill
Lynch 1-5-Year Government Bond Index, it was reasonable to expect that the
year's overall decline in interest rates would be more productive to our total
return. But markets do not always behave as investors believe they will. When
troubles abroad threatened the safety of foreign bonds, the result was a
stampeding "flight to quality," with U.S. Treasury bonds almost exclusively
being the securities of choice. Consequently, there was a broad sell-off of all
other types of bonds, including U.S. agency securities. Because we held more
government agency securities, and fewer Treasuries, than our benchmark, we
underperformed.
 
Fortunately, we believe a reversal of this unusual situation should occur, which
would boost the Fund's performance relative to our benchmark.
 
Q. WITH ALL THIS MOVEMENT IN THE MARKET, WHAT STEPS DID YOU TAKE TO HELP
INCREASE CURRENT INCOME?
 
A. Our key strategy was to sell Treasury notes and buy government agency notes,
which yielded considerably more income. For example, we sold Treasuries and
bought Tennessee Valley Authority notes (5.3% of the Fund's net assets), which
offered an additional .65% in yield. We also sold Treasury notes and bought
notes issued by the Federal Farm Credit Bank (12.8%), which netted an additional
 .34% in yield.*
 
As of December 31, 1998, 47.2% of the Fund's portfolio was invested in Treasury
securities, with 49.0% invested in government agencies and 3.8% in cash and cash
equivalents.*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We are essentially positive on the bond market. In our opinion, it is
unlikely that we will have another dramatic decline in interest rates, as we did
in 1998. We see many factors that are positive for bonds: the continuing secular
trend in disinflation, the very low levels of commodity prices, excessive global
production capacity, technological efficiencies and demographic trends. All of
these circumstances favor low inflation, which is good for fixed-income
investors.
 
This is not to say that there are not negative factors that pose risks to the
bond market. The most prominent of these are shortages in the domestic labor
force, which can run up costs and spark inflation; the introduction of the new
euro currency in Europe, which could make U.S. debt less desirable; and the
possibility of an overheating U.S. economy.
 
But in general, we feel that bonds should remain stable, with the yields of
long-term Treasuries remaining in the range of 4.5% to 5.5%.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 3/3/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12b-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12b-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 12/14/98 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The ISG Limited Term U.S. Government Fund commenced operations on 2/28/97
through a transfer of assets from certain collective trust fund ("commingled")
accounts managed by First American National Bank, using materially equivalent
investment objectives, policies and methodologies as the Fund. The quoted
performance of the Fund includes performance of the commingled accounts for
periods prior to the Fund's commencement of operations, as adjusted to reflect
the expenses associated with the Fund. 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 also reflects
reinvestment of dividends and capital gain distributions.
 
The Fund's performance is compared to the Merrill Lynch 1-5-Year Government Bond
Index, which is generally representative of the performance of government bonds
in that maturity range with a rating of at least Baa. The Index is unmanaged and
does not reflect the expenses associated with a mutual fund, such as investment
management and fund accounting fees. The Fund's performance reflects the
deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

 INVESTMENT GOAL
 The Fund seeks to provide investors with current income without assuming undue
 risk. It invests primarily in securities guaranteed as to payment of principal
 and interest by the U.S. Government, its agencies or instrumentalities. This
 Fund is suitable for investors seeking regular monthly income without undue
 risk to principal.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING 1998?
 
A. Despite all the turmoil we saw in the credit markets during the period, and
perhaps because of it, the Fund turned in a very satisfactory performance. For
the 12 months ended December 31, 1998, the Fund produced a total return of 8.95%
(Class A shares at NAV).(1) In comparison, the Merrill Lynch
Government/Corporate Master Index, produced a total return of 9.53%. We achieved
our objectives while maintaining an average credit quality of AAA. As of
December 31, 1998, the Fund's average maturity was 8.6 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. A number of significant events had an impact on interest rates and bond
prices. First there was a series of international crises--particularly the
economic meltdown last summer in Russia, which resulted in that country
defaulting on its debt. Then came the collapse of the huge hedge fund, Long-Term
Capital Management, which threatened to throw the world's markets into chaos.
 
These events frightened a lot of investors into selling every type of debt
security except U.S. Treasury securities, and pouring cash into Treasuries.
Funds overweighted in Treasuries, such as ours, profited from this set of
circumstances.
 
We also benefited from favorable interest-rate moves. Over the course of the
year, the long-term Treasury yields fell more than one percent, a substantial
change, with most of that coming in the last six months. Additionally, the
Federal Reserve cut short-term interest rates three times in the last four
months of the year. As rates fall, bond prices generally rise, and this also
helped the Fund's performance.
 
Q. WHAT STRATEGIES DID YOU EMPLOY?
 
A. We extended our maturity and duration slightly during the year. Normally, we
are not comfortable making big interest-rate bets, but we anticipated that
interest rates could remain stable or fall, and we wanted to be in the position
to profit from such a move. When rates did fall, investors focused on the types
of Treasury securities we owned, and therefore the Fund's NAV rose.
 
Because many of our shareholders are seeking high current income, we also took
steps to lock in better yields. We bought noncallable government agency
bonds--such as those offered by Fannie Mae--which provided significantly higher
income than similar Treasury issues.
 
During much of the year, roughly 20% to 25% of the Fund's assets were invested
in corporate bonds. As of December 31, 1998, 83.2% of the Fund's portfolio was
invested in U.S. Treasury, government agency and mortgage pass-through
securities, with 13.9% invested in corporate debt and 2.9% in cash equivalents.*
 
Q. WHAT IS YOUR OUTLOOK?
 
A. We continue to be positive on the bond market. In our opinion, it is unlikely
that we will have another dramatic decline in interest rates as we did in 1998.
We see many factors that are positive for bonds: the continuing secular trend in
disinflation, the very low levels of commodity prices, excessive global
production capacity, technological efficiencies and demographic trends. All of
these circumstances favor low inflation, which is good for fixed-income
investors.
 
This is not to say that there are not negative factors that pose risks to the
bond market. The most prominent of these are shortages in the domestic labor
force, which can run up costs and spark inflation; the introduction of the new
euro currency in Europe, which could make U.S. debt less desirable; and the
possibility of an overheating U.S. economy.
 
But, in general, we feel that bonds should remain stable, with yields on
long-term Treasuries remaining in the range of 4.5% to 5.5%.

  Since Inception 8/3/92.................       6.89%
</TABLE>
 
The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
The quoted returns reflect the performance from 8/3/92 to 12/14/98 of the DG
Government Income Fund, an open-end investment company that was the predecessor
fund to the ISG Government Income Fund.
 
The Institutional Share class was initially offered on 12/14/98 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The Fund's performance is compared to the Merrill Lynch Corporate/Government
Master Index, which is generally representative of the performance of corporate
and U.S. Government bonds. The index is unmanaged and does not reflect the
expenses associated with a mutual fund, such as investment management and fund
accounting fees. The Fund's performance reflects the deduction of fees for these
value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

      The Government Income Fund invests primarily in securities issued or
      guaranteed by the U.S. Government, its agencies and
      instrumentalities, and also may invest in investment-grade U.S.
      dollar-denominated, fixed income securities of other issuers. The
      Fund is designed to provide current income without assuming undue
      risk. The Fund's adviser has latitude in deciding how assets are
      invested among corporate and government obligations. As a result,
      the Fund enjoys flexibility to make the most of changing market
      conditions.

      maturities greater that 20 years.

 INVESTMENT GOAL
 The Fund seeks to provide investors with current income exempt from federal
 income tax. The Fund invests primarily in investment-grade municipal
 obligations issued by state and local entities across the United States.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. For the 12 months ended December 31, 1998, the Fund produced a total return
of 5.33% (Class A Shares at NAV).(1) In comparison, the Fund's benchmarks, the
Lipper Municipal General Bond Index(2) and the Lehman Brothers Municipal Bond
Index, produced a total return of 5.62% and 5.84%, respectively.
 
We achieved our objectives while maintaining an average credit quality of AA1
(as rated by Moody's) and AA+ (Standard & Poor's). As of December 31, 1998, the
Fund's average maturity was 5.7 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. Bonds, in general, performed well in 1998, and it was a pretty strong year
for municipal bonds, as well. Our Fund benefited from this positive environment
for fixed-income securities.
 
A succession of near-calamitous events throughout the world--including the
economic crisis in Russia and the near collapse of the Long-Term Capital
Management hedge fund--had a major impact on fixed-income securities, and the
resulting volatility trickled down to the municipal bond market. But we profited
from the fact that the structure of our Fund performed particularly well in this
climate of uncertainty. We held a number of higher-coupon, noncallable bonds,
and some longer term, discounted issues that reacted positively and rose in
price. We took advantage of the circumstances and sold a number of our holdings
for prices well in excess of what we paid for them.
 
Q. WHAT ARE A FEW OF YOUR FAVORITE BONDS IN THE FUND?
 
A. We like the Seattle, Washington, 6.25%, due 2010 (1.0% of the Fund's net
assets). The bond has a good coupon and is noncallable; the issuer cannot call
the bond back before maturity. And it is not a run-of-the-mill variety of
bond--it is something of a specialty issue--and, in our opinion, would easily
sell if we chose to do so. Another favorite is the Massachusetts Bay Transit,
4.75%, due 2017 (1.7%). This bond is trading at a discount, due to the length of
the bond and the lower coupon, and it fits very nicely in our Fund.*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We believe we should have a good year in the municipal markets. It is
possible that we could see some volatility, just as we did in 1998; many
economic questions throughout the world have not been answered, and uncertainty
leads to fluctuations in rates and prices.
 
We have begun 1999 in a positive direction, but we would not be surprised to see
a pullback sometime in the near future. But the trend for interest rates is
down, which will help all fixed-income securities, including municipal bonds.
Our diversification across regional lines should help to provide additional
stability.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
The quoted returns reflect the performance from 12/29/92 to 12/14/98 of the DG
Municipal Income Fund, an open-end investment company that was the predecessor
fund to the ISG Municipal Income Fund.
 
The Institutional Share class was initially offered on 12/14/98 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The Fund's performance is compared to the Lehman Brothers Municipal Bond Index,
which is generally representative of the performance of investment-grade,
fixed-rate, long-term municipal bonds. The index is unmanaged and does not
reflect the expenses associated with a mutual fund, such as investment
management and fund accounting fees. The Fund's performance reflects the
deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

</TABLE>
 
- ---------------------------------------------------------------
- ---------------------------------------------------------------
 
 INVESTMENT GOAL
 The Fund seeks to provide investors with current income exempt from federal
 and Tennessee state income taxes without assuming undue risk. The Fund
 invests primarily in investment-grade Tennessee municipal obligations that
 generally have a duration of under five years, producing an effective
 average Fund maturity ranging between three and five years.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. For the 12 months ended December 31, 1998, the Fund produced a total return
of 3.76% (Class A shares at NAV).(1) In comparison, the Lehman Brothers
Municipal 1-5-Year Index produced a total return of 5.84%.
 
It is also important to recognize income yield to shareholders. As of December
31, 1998, the Fund's 30-day SEC yield was 2.53% (Class Shares A at NAV). For
investors in the 36% federal income tax bracket, that is equivalent to a taxable
yield of 3.83%. The yield percentages are annualized.
 
We achieved our objectives while maintaining an average credit quality of AA1
(as rated by Moody's) and AA+ (Standard & Poor's). As of December 31, 1998, the
Fund's average maturity was 4.0 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. A succession of near-calamitous events throughout the world--including the
economic crisis in Russia and the collapse of the Long-Term Capital Management
hedge fund--had a major impact on fixed-income securities, and the resulting
volatility trickled down to the municipal bond market.
 
Bonds, in general, performed well in 1998, and it was a pretty strong year for
municipal bonds, as well. Our Fund benefited from this positive environment for
fixed-income securities.
 
Closer to home, Tennessee's economy remained fairly strong, although it slowed
down a bit from its previously torrid pace. Supply was kind of a nonevent for
the year as a whole; generally, the supply of new muni issues in the state
remained at comfortable levels throughout 1998.
 
Q. WHAT ARE A FEW OF YOUR FAVORITE BONDS IN THE FUND?
 
A. We like the Rutherford County, 6.00%, due in 2004 (7.4% of the Fund's net
assets). This bond is on the longer end of our spectrum. It offers a good coupon
and is noncallable; the issuer cannot call it back before maturity. Also, there
are not a lot of Rutherford County bonds in the market, which, in our opinion,
would make this paper easy to sell if we chose to do so. Another favorite is
Montgomery County, 5.10%, due 2011 (3.7%). This bond is not callable until 2008
and has performed well for us.*
 
Q. WHAT IS YOUR OUTLOOK FOR THE REMAINDER OF 1999?
 
A. We believe we should have a good year in the municipal markets, including
Tennessee. It is possible that we could see some volatility, just as we did in
1998; many economic questions throughout the world have not been answered, and
uncertainty leads to fluctuations in rates and prices.
 
We have begun 1999 in a positive direction, but we would not be surprised to see
a pullback sometime in the near future. But the trend for interest rates is
down, which will help all fixed-income securities, including munis.
 
- ---------------
(1) Including the 3.00% sales load, the Fund's return was 0.68% for the period.
 
* The Fund's portfolio composition is subject to change.
 
Regional funds may be subject to additional risk, since the companies they
invest in are located in one geographical location.
 
The Fund's income may be subject to certain state and local taxes and, depending
on your tax status, the federal alternative minimum tax.

  THE DATA FOR CLASS B SHARES PRIMARILY PRESENTS THE
  RESULTS OF THE CLASS A SHARES. ACTUAL CLASS B SHARES
  AVERAGE ANNUAL TOTAL RETURN AND HYPOTHETICAL GROWTH
  RESULTS WOULD HAVE BEEN LOWER. SEE NOTES BELOW.

 
 
The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 2/3/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12b-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12b-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The ISG Limited Term Tennessee Tax-Exempt Fund commenced operations on 2/28/97
through a transfer of assets from certain collective trust fund ("commingled")
accounts managed by First American National Bank, using materially equivalent
investment objectives, policies and methodologies as the Fund. The quoted
performance of the Fund includes performance of the commingled accounts for
periods prior to the Fund's commencement of operations, as adjusted to reflect
the expenses associated with the Fund. 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 also reflects
reinvestment of dividends and capital gain distributions.
 
The Fund's performance is compared to the Lehman Brothers Municipal 1-5-Year
Index, an unmanaged index that is generally representative of municipal bonds
with maturities between 1 and 5 years. The index is unmanaged and does not
reflect the expenses associated with a mutual fund, such as investment
management and fund accounting fees. The Fund's performance reflects the
deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

      The Limited Term Tennessee Tax-Exempt Fund invests primarily in a
      portfolio of investment-grade Tennessee municipal obligations that,
      under normal market conditions, have a duration of under five years
      and an effective average portfolio maturity ranging between 3 and 5
      years. With an emphasis on quality, the Fund seeks to generate
      current income that is exempt from federal and Tennessee state
      income taxes without undue risk to principal.

- ---------------------------------------------------------------
- ---------------------------------------------------------------
 INVESTMENT GOAL
 The Fund seeks to provide investors with current income exempt from federal
 and Tennessee state income taxes without assuming undue risk. The Fund invests
 primarily in investment-grade Tennessee municipal obligations and is suitable
 for Tennessee residents seeking monthly state income exempt from both federal
 and Tennessee personal income taxes. The Fund affords greater diversification
 and liquidity than most investors would achieve by purchasing municipal
 securities directly.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. For the 12 months ended December 31, 1998, the Fund produced a total return
of 4.25% (Class A shares at NAV).(1) In comparison, the Fund's benchmarks, the
Lipper States Intermediate Municipal Average(2) and the Lehman Brothers
Municipal 10-Year Index, produced a total return of 5.08% and 6.11%,
respectively.
 
It is also important to recognize income yield to shareholders. As of December
31, 1998, the Fund's 30-day SEC yield was 2.82% (Class A Shares at NAV). For
investors in the 36% federal income tax bracket, that is equivalent to a taxable
yield of 4.41%. The yield percentages are annualized.
 
We achieved our objectives while maintaining an average credit quality of AA1
(as rated by Moody's) and AA+ (Standard & Poor's). As of December 31, 1998, the
Fund's average maturity was 8.4 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. Bonds, in general, performed well in 1998, and it was a pretty strong year
for municipal bonds, as well. Our Fund benefited from this positive environment
for fixed-income securities.
 
We switched gears late in the first quarter and early in the second quarter.
Seeking more tax-exempt income for our shareholders, we emphasized buying
noncallable bonds, or longer-term callable bonds with higher coupons (interest
payments). The driving force behind this mild shift in our strategy was our
understanding that the majority of our shareholders are most interested in
tax-free income.
 
A succession of near-calamitous events throughout the world--including the
economic crisis in Russia and the near-collapse of the Long-Term Capital
Management hedge fund--had a major impact on fixed-income securities, and the
resulting volatility trickled down to the municipal bond market. It was our
belief that the type of higher-coupon bonds we were buying were more likely to
hold up better in a volatile environment, and indeed, our increased yields
served us well during market fluctuations.
 
Closer to home, Tennessee's economy remained fairly strong, although it slowed
down a bit from its previously torrid pace. Supply was kind of a nonevent for
the year as a whole; generally, the supply of new muni issues in the state
remained at comfortable levels throughout 1998.
 
We also took steps to make this an all-Tennessee fund; we sold most of our
out-of-state holdings and used the proceeds to buy Tennessee municipal bonds.
The vast majority of our shareholders are residents of Tennessee, and we wanted
to give them the greatest possible tax advantage.
 
Q. WHAT ARE A FEW OF YOUR FAVORITE BONDS IN THE FUND?
 
A. Among our favorite bonds is the Dickson County, 6.25%, due 2008 (1.4% of the
Fund's net assets). The bond provides a nice amount of income, and it is
noncallable, so the issuer cannot take it back before it matures. Also, there
are not many Dickson County bonds in the market. If the time came and we wanted
to make a change, in our opinion, this bond would be easy to sell. At the longer
end of the market, we like the Blount County, 5.00%, due 2019 (1.0%). For most
of the year, it was trading at a discount. As interest rates moved lower, we
picked up some price appreciation. It is a callable bond, but the bond is not
callable until 2008, so we have some call protection.*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We believe we should have a good year in the municipal markets, including
Tennessee. It is possible that we could see some volatility, just as we did in
1998; many economic questions throughout the world have not been answered, and
uncertainty leads to fluctuations in rates and prices.
 
We have begun 1999 in a positive direction, but we would not be surprised to see
a pullback sometime in the near future. But the trend for interest rates is
down, which will help all fixed-income securities, including municipal bonds.
 
- ---------------
(1) Including the 3.00% sales load, the Fund's return was 1.18% for the period.
 
(2) The Lipper States Intermediate Municipal Average is comprised of managed
    funds that invest in municipal debt issues that have dollar-weighted average
    maturities of five to ten years and are exempt from taxation on a specified
    city or state basis.
 
* The Fund's portfolio composition is subject to change.
 
Regional funds may be subject to additional risk, since the companies they
invest in are located in one geographical location.
 
The Fund's income may be subject to certain state and local taxes and, depending
on your tax status, the federal alternative minimum tax.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 2/24/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12B-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 10/3/97 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The ISG Tennessee Tax-Exempt Fund commenced operations on 3/28/94 through a
transfer of assets from certain collective trust fund ("commingled") accounts
managed by First American National Bank, using materially equivalent investment
objectives, policies and methodologies as the Fund. The quoted performance of
the Fund includes performance of the commingled accounts for periods prior to
the Fund's commencement of operations, as adjusted to reflect the expenses
associated with the Fund. 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 also reflects reinvestment of
dividends and capital gain distributions.
 
The Fund's performance is compared to the Lehman Brothers Municipal 10-Year
Index, an unmanaged index that includes municipal bonds issued within the last
five years by municipalities throughout the United States, with maturities of at
least one year, but no more than 12 years, and a credit quality of at least Baa.
The Index is unmanaged and does not reflect the expenses associated with a
mutual fund, such as investment management and fund accounting fees. The Fund's
performance reflects the deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

 INVESTMENT GOAL
 The Fund 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 less than four years. This Fund is suitable for investors seeking
 regular monthly income without undue risk to principal.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING 1998?
 
A. Despite some volatility in the market throughout the year, the Fund delivered
solid returns. For the 12 months ended December 31, 1998, the Fund produced a
total return of 6.48% (Class A shares at NAV).(1) In comparison, the Merrill
Lynch 1-5-Year Government/Corporate Bond Index produced a total return of 9.53%.
 
It is also important to recognize income yield to shareholders. As of December
31, 1998, the Fund's 30-day SEC yield was 4.06% (Class A shares at NAV),
compared to 5.92% at the end of 1997. The yield percentages are annualized. We
achieved our objectives while maintaining an average credit quality of AA-(rated
by Standard & Poor's). As of December 31, 1998, the Fund's average maturity was
3.1 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. The two most important factors were our maturity structure and the
international crises that afflicted Russia, Asia and South America.
 
With the Fund having a maturity structure longer than our benchmark, the Merrill
Lynch 1-5-Year Government/Corporate Bond Index, it was reasonable to expect that
the year's overall decline in interest rates would be more productive to our
total return. But markets do not always behave as investors believe they will.
When troubles abroad threatened the safety of foreign bonds, the result was a
stampeding "flight to quality," with U.S. Treasury bonds almost exclusively
being the securities of choice. Consequently, there was a broad sell-off of all
other types of bonds, including U.S. government agency securities. Because we
held more corporate bonds and government agencies bonds, and fewer Treasuries,
than our benchmark (which held approximately 85% Treasuries), we underperformed
the benchmark.
 
Fortunately, we believe a reversal of this unusual situation should occur, which
would boost the Fund's performance relative to our benchmark.
 
Q. WITH ALL THIS MOVEMENT IN THE MARKET, WHAT STEPS DID YOU TAKE TO HELP
INCREASE CURRENT INCOME?
 
A. Our key strategy was to sell Treasury notes and buy higher-yielding corporate
securities, which yielded considerably more income. For example, we sold
Treasuries and bought bonds issued by AutoZone (2.2% of the Fund's net assets),
and Anheuser-Busch notes (1.4%). AutoZone offered more than 1% in additional
yield, and Anheuser-Busch netted an additional 1.73% yield.
 
As of December 31, 1998, 72.3% of the Fund's portfolio was invested in corporate
bonds, with a total of 25.8% invested in Treasury, government agency and
mortgage pass-through securities, and 1.9% in cash equivalents.*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We are essentially positive on the bond market. In our opinion, it is
unlikely that we will have another dramatic decline in interest rates as we did
in 1998. We see many factors that are positive for bonds: the continuing secular
trend in disinflation, the very low levels of commodity prices, excessive global
production capacity, technological efficiencies and demographic trends. All of
these circumstances favor low inflation, which is good for fixed-income
investors.
 
This is not to say that there are not negative factors that pose risks to the
bond market. The most prominent of these are shortages in the domestic labor
force, which can run up costs and spark inflation; the introduction of the new
euro currency in Europe, which could make U.S. debt less desirable; and the
possibility of an overheating U.S. economy.
 
But in general, we feel that bonds could remain stable, with yields on long-term
Treasuries remaining in the range of 4.5% to 5.5%. If anything, we believe there
is a greater probability that yields could fall to the lower end of this range
than rise.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 2/4/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12B-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 10/3/97 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The ISG Limited Term Income Fund commenced operations on 3/28/94 through a
transfer of assets from certain collective trust fund ("commingled") accounts
managed by First American National Bank, using materially equivalent investment
objectives, policies and methodologies as the Fund. The quoted performance of
the Fund includes performance of the commingled accounts for periods prior to
the Fund's commencement of operations, as adjusted to reflect the expenses
associated with the Fund. 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 also reflects reinvestment of
dividends and capital gain distributions.
 
The Fund's performance is compared to the Merrill Lynch 1-5-Year
Government/Corporate Bond Index, which is generally representative of the
performance of government and corporate bonds in that maturity range with a
rating of at least Baa. The index is unmanaged and does not reflect the expenses
associated with a mutual fund, such as investment management and fund accounting
fees. The Fund's performance reflects the deduction of fees for these
value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

 INVESTMENT GOAL
 The Fund 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 average maturities of 8 to 13 years. This Fund is suitable for
 investors seeking regular monthly income without undue risk to principal.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. Despite some volatility in the market throughout the year, the Fund delivered
historically solid returns. For the 12 months ended December 31, 1998, the Fund
produced a total return of 8.28% (Class A shares at NAV).(1) In comparison, the
Merrill Lynch Corporate/Government Master Index, produced a total return of
9.53%.
 
It is also important to recognize income yield to shareholders. As of December
31, 1998, the Fund's 30-day SEC yield was 4.11% (Class A shares at NAV),
compared to 5.89% at the end of 1997. The yield percentages are annualized. We
achieved our objectives while maintaining an average credit quality of A+ (rated
by Standard & Poor's). As of December 31, 1998, the Fund's average maturity was
11.8 years.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. The two most important factors were our maturity structure and the
international crises that afflicted Russia, Asia and South America.
 
With the Fund having a maturity structure longer than our benchmark, the Merrill
Lynch Corporate/Government Master Index, it was reasonable to expect that the
year's overall decline in interest rates would be more productive to our total
return. But markets do not always behave as investors believe they will. When
troubles abroad threatened the safety of foreign bonds, the result was a
stampeding "flight to quality", with U.S. Treasury bonds almost exclusively
being the securities of choice. Consequently, there was a broad sell-off of all
other types of bonds, including U.S. government agency securities. Because we
held more corporates and government agency bonds, and fewer Treasuries, than our
benchmark (which held 68% Treasuries), we underperformed the benchmark.
 
Fortunately, we believe a reversal of this unusual situation should occur, which
would boost the Fund's performance relative to Treasuries and our benchmark.
 
Q. WITH ALL THIS MOVEMENT IN THE MARKET, WHAT STRATEGIES DID YOU EMPLOY TO HELP
INCREASE CURRENT INCOME?
 
A. First, we sold Treasuries and bought corporate bonds, which yielded
considerably more income. One example was Caterpillar Tractor bonds (3.1% of the
Fund's net assets), which yielded nearly one percent more than the Treasuries we
sold. We also liquidated Freddie Mac notes and bought corporate notes issued by
AutoZone (2.5%), which offered an additional .63% more than the Freddie Mac
securities.*
 
Second, we swapped one corporate note for another when the yields between them
got out of line. For example, we sold BancOne notes and bought securities issued
by Anheuser-Busch (2.9%). This particular trade netted an additional .50% in
yield, for what we believe to be no additional credit risk.*
 
As of December 31, 1998, 87.2% of the Fund's portfolio was invested in corporate
bonds, with a total of 10.5% invested in U.S. Treasury, government agency and
mortgage pass-through securities, 1.1% in taxable municipal bonds and 1.2% in
cash equivalents.*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We are essentially positive on the bond market. Although it is unlikely that
we will have another dramatic decline in interest rates, as we did in 1998, we
see many factors that are positive for bonds: the continuing secular trend in
disinflation, the very low levels of commodity prices, excessive global
production capacity, technological efficiencies and demographic trends. All of
these circumstances favor low inflation, which is good for fixed-income
investors.
 
This is not to say that there are not some negative factors that pose risks to
the bond market. The most prominent of these are shortages in the domestic labor
force, which can run up costs and spark inflation; the introduction of the new
euro currency in Europe, which could make U.S. debt less desirable; and the
possibility of an overheating U.S. economy.
 
But in general, we feel that bonds should remain stable, with yields on
long-term Treasuries remaining in the range of 4.5% to 5.5%. If anything, we
believe there is a greater probability that yields could fall to the lower end
of this range than that they could rise.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 2/4/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12B-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 10/3/97 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The ISG Income Fund commenced operations on 4/1/96 through a transfer of assets
from certain collective trust fund ("commingled") accounts managed by First
American National Bank, using materially equivalent investment objectives,
policies and methodologies as the Fund. The quoted performance of the Fund
includes performance of the commingled accounts for periods prior to the Fund's
commencement of operations, as adjusted to reflect the expenses associated with
the Fund. 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 also reflects reinvestment of dividends and
capital gains distributions.
 
The Fund's performance is compared to the Merrill Lynch Corporate/Government
Master Index, which is generally representative of the performance of corporate
and U.S. Government bonds. The index is unmanaged and does not reflect expenses
associated with a mutual fund, such as investment management and fund accounting
fees. The Fund's performance reflects the deduction of fees for these
value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

The Income Fund invests primarily in investment-grade, U.S. dollar denominated
fixed-income securities of domestic and foreign issuers. The Fund is designed to
provide current income without assuming undue risk. The Fund's adviser has
latitude in deciding how assets are invested among corporate and government
obligations. As a result, the Fund enjoys flexibility to make the most of
changing market conditions.

 INVESTMENT GOAL
 The Fund seeks to provide investors with current income and capital
 appreciation. The Fund invests primarily in dividend-paying equity securities
 of domestic issuers that are expected to provide reasonable income and may
 have capital appreciation potential.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. For the 12 months ended December 31, 1998, the Fund's total return was 19.46%
(Class A shares at NAV).(1) In comparison, the Lipper Equity Income Fund
Index(2) rose 11.78%, and the Standard & Poor's 500 Stock Index rose 28.74% for
the period.
 
We were very satisfied with the Fund's total return. We not only outperformed
the Lipper Equity Income Fund Index by nearly 8%, but did so while providing
shareholders with healthy yields. Strong capital appreciation helped
shareholders, while higher-than-average current income smoothed out some of the
market's volatility.
 
Q. WHAT FACTORS LED TO THESE STRONG RETURNS?
 
A. The three primary sectors for an equity income fund such as ours are energy,
financial services and utilities. In 1998, none of these sectors did
particularly well; energy stocks were especially lethargic. Because we were not
able to depend on our traditional areas, we relied on successful stock picking
within other sectors.
 
We had some very good stock picks such as: Wal-Mart Stores (1.2% of the Fund's
net assets), which we owned the entire year, and which was up 106% in 1998.
Other big winners included General Electric (2.0%), Pitney Bowes (1.9%), United
Technologies (1.8%), McGraw-Hill (0.1%) and Fannie Mae (3.1%). Some of our
pharmaceutical stocks did very well, such as Schering-Plough (2.3%), Glaxo
Wellcome PLC (2.7%) and Abbott Labs (1.7%). Xerox (1.2%), IBM (0.6%) and
Automatic Data Processing (2.4%) were among our leading technology holdings. A
lot of these winners were among our top 10 holdings throughout the year, and
they really drove the Fund's performance.*
 
Q. WITH THE FUND'S STRONG TOTAL RETURN, WERE YOU ABLE TO PROVIDE SHAREHOLDERS
WITH AN ABOVE-AVERAGE YIELD?
 
A. Yes. As of December 31, 1998, the Fund's yield was 2.3%, versus 1.3% for the
S&P 500. This relatively high yield cushioned the Fund against some of the
volatility we saw during the year, particularly during the market correction in
August and September. During that time, the Fund went down less than the general
market. Our yield was boosted by our significant holdings in the utility sector
and in real estate investment trusts (REITs). Overall, REITs were poor
performers in 1998, but they did provide steady income, which was especially
comforting when the market turned down. We feel very positive about REITs going
forward. We believe REITs offer the potential for good total returns during the
next year--an attractive combination of capital appreciation and generous
income. Many REITs are available with yields in the 7% range, supported by the
requirement that REITs must pay out 95% of their earnings each year to their
shareholders.
 
Q. WHAT IS YOUR STRATEGY FOR 1999?
 
A. We expect to see more volatility and uncertainty in the markets. A number of
factors -- such as fallout from President Clinton's impeachment trial, economic
weakness in South America and Asia, and continued concerns about growth in the
U.S. economy -- could strike the financial markets.
 
With all of these potential perils, we will attempt to focus on companies that
have reasonably predictable earnings -- not just for the next year, but looking
out for five years or more. We believe we can make a reasonable assumption about
the predictability of earnings for such companies as Fannie Mae (3.1%), Dayton
Hudson (3.1%), PepsiCo (2.6%) and Campbell's Soup (2.1%). Even if the political
and economic situations remain unsettled, people will still buy houses, drink
soda pop and eat snack food.*

(1) Including the 4.75% sales load, the Fund's return was 13.76% for the period.
 
(2) The Lipper Equity Income Fund Index is comprised of managed funds that are
    generally representative of funds that invest more than 60% of their assets
    in equities.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 2/3/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12B-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 10/3/97 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The ISG Equity Income Fund commenced operations on 2/28/97 through a transfer of
assets from certain collective trust fund ("commingled") accounts managed by
First American National Bank, using materially equivalent investment objectives,
policies and methodologies as the Fund. The quoted performance of the Fund
includes performance of the commingled accounts for periods prior to the Fund's
commencement of operations, as adjusted to reflect the expenses associated with
the Fund. 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 also reflects reinvestment of dividends and
capital gains distributions.
 
The Fund's performance is compared to the Standard & Poor's 500 Stock Index, a
broad measure of the stock market as a whole. The index is unmanaged and does
not reflect the expenses associated with a mutual fund, such as investment
management and fund accounting fees. The Fund's performance reflects the
deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

 INVESTMENT GOAL
 The Fund seeks to provide investors with long-term capital appreciation by
 investing primarily in large-capitalization stocks (market caps over $1
 billion). The Fund's holdings are typically characterized by higher-
 than-average returns on equity, superior long-term earnings-per-share
 growth rates, and consistent earnings generation. This Fund is suitable for
 investors who are investing for the long-term and are willing to assume the
 additional risk of investing in growth stocks in return for potentially
 higher total returns.
 
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. We outperformed our long-term benchmark by a considerable margin. For the 12
months ended December 31, 1998, the Fund's total return was 37.87% (Class A
Shares at NAV).(1) In comparison, the Standard & Poor's 500 Stock Index
generated a 28.74% total return.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. During the period, large-caps as a group outperformed smaller issues, while
growth-style stocks generally outperformed value stocks. With our orientation
directed at large-cap growth stocks, we very much benefited from these disparate
market trends. Over full market cycles, we expect the stocks in our Fund to
average significantly higher earnings-per-share growth rates than those of the
S&P 500. Such a robust growth rate differential has been generously rewarded in
recent years and will likely continue to be so favored in the future, we
believe.
 
We believe our Fund's outperformance also was enhanced by other facets of our
investment strategy. For one thing, we are very single-minded in our approach to
selecting and buying stocks. If a potential candidate is not a growth stock, we
do not buy it. We never knowingly stray from having a 100% true growth
portfolio. We also believe in giving our companies ample time to perform. Our
annual turnover rate is in the neighborhood of 5%, which means that, on average,
we hold stocks for approximately 20 years. We are long-term investors; we do not
waiver from our strategy in an attempt to seize upon and benefit from short-term
trends.
 
Additionally, we focus on a relatively small number of good companies whose
managements' have demonstrated, over long periods of time, the ability to
realize the full growth potential of their companies, year in and year out.
 
Finally, we do not rotate our holdings from one economic sector to another. We
are more or less indifferent to sector weighting, with the exception being our
belief that certain sectors of the U. S. economy are more likely than others to
offer the type of growth opportunities we pursue over time. Taken in consort,
all of these factors contributed to our having such a good year in 1998.
 
Q. WHAT STOCKS PERFORMED WELL FOR YOU?
 
A. The Consumer Cyclicals sector did very well for us. We enjoyed significant
market gains from such holdings as Gap Stores (1.3% of the Fund's net assets),
Home Depot (3.2%) and Wal-Mart Stores (2.3%). Another consumer-related area,
Consumer Staples, was productive, although not universally so. Solid returns
were posted by Walgreen (4.1%), McDonald's (2.9%) and Albertson's (1.5%).*
 
Still another economic sector that will, we believe, continue to offer a great
opportunity for long-term growth is Health Care. During the last 12 months, we
owned a number of Healthcare winners, including Amgen (1.1%), Pfizer (3.2%),
Schering-Plough (3.6%), Medtronic (2.6%) and Merck (2.9%).*
 
Possibly most importantly, we have been, and are still, very optimistic about
the Fund's largest economic sector, Technology, and its great potential for the
future. Some of our most productive "tech" holdings over the last year were
Lucent Technologies (1.5%), Sun Microsystems (1.3%), Microsoft (3.2%), Oracle
(0.9%), IBM (4.3%), Compaq (4.0%), Applied Materials (1.1%) and Automatic Data
Processing (2.6%).*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We believe that the first quarter is likely to be stronger than most
prognosticators now expect. However, later in the year, there could very well be
some slowing in the economy. How will that relative weakness be reflected in the
stock market and in the issues we hold? Most likely, all other things being
equal, our stocks will trade in sympathy, but not necessarily in union, with the
overall market and the broad market indicators.
 
However, in the long run, the success of our Fund may have a good deal more to
do with interest rate direction than with earnings-per-share growth rates. In
our opinion, the extended and dramatic decline in interest rates largely
explains why growth-style stocks have done so well during the last 15 years. We
feel that interest rates will be the major determinant to future growth stock
performance. Nevertheless, we will continue to buy the stocks that we believe
are likely to outperform our benchmark in the long run, companies whose
earnings-per-share are relatively consistent from year to year, and of higher
relative predictability than our benchmark's earnings-per-share pattern.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
The quoted returns reflect the performance from 8/3/92 to 12/14/98 of the DG
Equity Fund, an open-end investment company that was the predecessor fund to the
ISG Large-Cap Equity Fund.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 12/15/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12B-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 12/14/98 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The Fund's performance is compared to the Standard & Poor's 500 Stock Index, a
broad measure of the stock market as a whole. The index is unmanaged and does
not reflect the expenses associated with a mutual fund, such as investment
management and fund accounting fees. The Fund's performance reflects the
deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

- ---------------------------------------------------------------
 INVESTMENT GOAL
 The Fund seeks to provide investors with 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 Fund 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 DID THE FUND PERFORM DURING THE PERIOD?
 
A. It was a good time to be invested in a growth fund. For the 12 months ended
December 31, 1998, the Fund's total return was 32.05% (Class A Shares at
NAV).(1) In comparison, the Lipper Growth Fund Index(2) was up 25.69%, and the
Standard & Poor's 500 Stock Index rose 28.74%.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. Our outperformance had as much to do with the stocks we
avoided -- particularly during the second half of the year -- as with the stocks
we owned. We had decreased our holdings in basic industry and energy stocks,
which helped, as both sectors badly underperformed the market. At the same time,
we were overweighted in three areas that did very well: technology, health care
and consumer cyclicals, the latter being comprised mostly of specialty
retailers. Because we were overweighted in three sectors that did much better
than the overall market, it is easy to understand why we did so well.
 
Another factor that helped us was our decision, some time late in the second
quarter, to lighten up on our small- and mid-capitalization stocks. By the end
of the year, we had only a small weighting in stocks with market caps under $8
billion. The decision to focus almost exclusively on large-cap stocks was very
deliberate and proved to be correct. Not only did growth stocks outperform value
stocks, but large-caps outperformed smaller issues by a wide margin.
 
Q. SO WITHIN SPECIFIC SECTORS, YOU SOLD SMALLER NAMES AND BOUGHT BIGGER ONES?
 
A. Yes. For example, in health care, we sold HEALTHSOUTH, Boston Scientific and
Centocor, and took new positions in Eli Lilly (1.8% of the Fund's net assets)
and Merck (1.4%). In the consumer cyclicals area, we sold Barnes &
Noble -- which was hurt by competitors, such as Amazon.com -- and Office Depot,
and bought Gap Stores (1.3%) and Best Buy (1.3%). And in technology, we added
several new names, including Hewlett Packard (2.3%), Xerox (2.0%) and America
Online (1.1%). America Online was particularly helpful; in the last four months
of the year, the stock tripled in price. In a related area, telecommunications,
we added MCI Worldcom (2.9%), which is second only to AT&T in long-distance
telecommunications; we think that, from the standpoint of technological
expertise, MCI Worldcom is in the forefront of its industry. *
 
Q. YOUR STRATEGY WAS TO BUY BIG AND BUY GROWTH?
 
A. Yes, and one more thing. We also felt, early in the year, that large
multinational companies would not necessarily do well. Consequently, we
liquidated positions that we felt could be hurt due to the turmoil in Asia and
elsewhere.
 
It was a stock-picker's market for just about the entire year. To outperform our
benchmark, you had to pick the right stocks, and we were fortunate to be right
most of the time.
 
Q. WHAT'S YOUR OUTLOOK FOR 1999?
 
A. The biggest wild card in the short run will be what the new euro currency
conversion will mean for American companies. We think it could end up creating
more competition for companies in the United States; that situation could
warrant more caution about the large multi-nationals. There also could be
consequences for the U.S. dollar -- which, in turn, could have implications for
our bond market and for stocks. If the dollar becomes significantly weak against
the new euro, the result could be higher interest rates and inflationary
pressure here in the United States.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 2/5/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES (WITHOUT SALES CHARGE)
PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE HIGHER 12B-1
FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC AND HIGHER
12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH FIGURES WOULD
HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 10/3/97 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The ISG Capital Growth Fund commenced operations on 4/1/96 through a transfer of
assets from certain collective trust fund ("commingled") accounts managed by
First American National Bank, using materially equivalent investment objectives,
policies and methodologies as the Fund. The quoted performance of the Fund
includes performance of the commingled accounts for periods prior to the Fund's
commencement of operations, as adjusted to reflect the expenses associated with
the Fund. 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 also reflects reinvestment of dividend and
capital gain distributions.
 
The Fund's performance is compared to the Standard & Poor's 500 Stock Index, a
broad measure of the stock market as a whole. The index is unmanaged and does
not reflect the expenses associated with a mutual fund, such as investment
management and fund accounting fees. The Fund's performance reflects the
deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

- ---------------------------------------------------------------
 INVESTMENT GOAL
 The Fund aggressively seeks to provide investors with the potential to achieve
 a high level of total return through investments in smaller, domestic,
 high-growth companies with small capitalizations. The Fund is most 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 DID THE FUND PERFORM DURING THE PERIOD?
 
A. It was a tough year for small-cap stocks. For the 12 months ended December
31, 1998, the Fund's total return was -7.20% (Class A shares at NAV).(1) In
comparison, the Russell 2000 Stock Index returned -2.55% for the period.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. Small-cap stocks, in general, underperformed large-cap issues. In our view,
the Fund has tended to outperform in years with positive market returns and
underperform in years with negative market returns. Because this was a negative
year for the types of stocks we select, we found the climate especially
challenging. In particular, our holdings in the oil and oil field service areas
hindered performance. When energy prices collapsed in late summer and early
fall, we were hurt by our exposure to those sectors.
 
However, we stayed true to our investment objective; unlike some other small-cap
funds, we did not chase after larger names just because they had momentum. This
past year, as always, we remained disciplined in our approach.
 
Q. WHAT IS YOUR INVESTMENT APPROACH?
 
A. We start by looking for stocks with a minimum of 20% growth in revenues
and/or earnings; that is our minimum cut. Beyond that, we are strong believers
in "growth at a reasonable price." We stay away from stocks with excessively
high price-to-earnings ratios, and we follow a bottom-up approach. We do our
homework, researching as many companies as we can find, that meet our basic
criteria. From a working list of approximately 100 companies, we perform
rigorous fundamental analysis and attempt to own between 40 and 60 of these
best-known stocks.
 
We also look at initial public offerings, or IPOs, because we think those are
the new growth companies for the future. And we try to take advantage of
inefficiencies in the market, identifying stocks that are under pressure for
various reasons that, we believe, will not adversely affect their earnings going
forward.
 
At the same time, if we think a stock we own is overvalued, we will sell it and
wait for the price to come back down. We also maintain a strict sell discipline,
and we will sell a stock if its earnings projections fall or its relative price
strength weakens.
 
Q. WHAT STOCKS PERFORMED WELL FOR YOU?
 
A. One stock that did well for us was Terex Corp. (3.4% of the Fund's net
assets), which is in the crane and equipment-lifting business. Arterial Vascular
Engineering (2.6%) has been a great stock for us; it recently was bought out by
Medtronics. In the restaurant group, Outback Steakhouse (2.2%) and Brinker
International (1.2%) did well. Other stocks that helped us were Cree Research
(5.9%), which is in the semiconductor business, and Insight Enterprises (3.2%),
which sells computers and computer peripherals through telemarketing and over
the Internet.*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. We are very optimistic of the coming year. The reason is, we believe the
valuations in the small-cap market are extremely attractive, versus the
overbought levels we see in some of the large-cap stocks. We believe there
continues to be plenty of money coming into the stock market and that investors
will realize that the growth they want is in small-company stocks.

+ Small-capitalization funds typically carry additional risks since smaller
  companies generally have a higher risk of failure. Historically, smaller
  companies' stocks have experienced a greater degree of market volatility than
  large company stocks on average.
 
 (1) Including the 4.75% sales load, the Fund's return was -11.60% for the
     period.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
The quoted returns reflect the performance from 8/1/94 to 12/14/98 of the DG
Opportunity Fund (the "Predecessor Fund"), an open-end investment company that
was the predecessor fund to the ISG Small-Cap Opportunity Fund.
 
PERFORMANCE FOR THE CLASS B SHARES, WHICH COMMENCED OPERATIONS ON 12/21/98, IS
BASED ON THE HISTORICAL PERFORMANCE OF THE CLASS A SHARES, (WITHOUT SALES
CHARGE) PRIOR TO THAT DATE. CLASS A SHARES PERFORMANCE DOES NOT REFLECT THE
HIGHER 12B-1 FEES OR THE CONTINGENT DEFERRED SALES CHARGE (CDSC). HAD THE CDSC
AND HIGHER 12B-1 FEES BEEN INCORPORATED, TOTAL RETURN AND HYPOTHETICAL GROWTH
FIGURES WOULD HAVE BEEN LOWER.
 
The Institutional Share class was initially offered on 12/14/98 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The Predecessor Fund commenced operations on 8/1/94 through a transfer of assets
from certain collective trust fund ("commingled") accounts managed by Deposit
Guaranty Corp., using materially equivalent investment objectives, policies and
methodologies as the Fund. The quoted performance of the Fund includes
performance of the commingled accounts for periods prior to the Fund's
commencement of operations, as adjusted to reflect the expenses associated with
the Fund. 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 also reflects reinvestment of dividends and
capital gain distributions.
 
The Fund's performance is compared to the Russell 2000 Stock Index, an unmanaged
index generally representative of the performance of small-capitalization
stocks. The Index is unmanaged and does not reflect expenses associated with a
mutual fund, such as investment management and fund accounting fees. The Fund's
performance reflects the deduction of fees for these value-added services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

LAZARD INTERNATIONAL EQUITY INVESTMENT TEAM
Portfolio Manager
ISG International Equity Fund+
 
- ---------------------------------------------------------------
- ---------------------------------------------------------------
 INVESTMENT GOAL
 The Fund seeks to provide investors with capital appreciation. The Fund
 invests primarily in the equity securities of foreign issuers that the Fund
 manager considers undervalued based on their return on total capital or
 equity. The Fund expects to invest primarily in the stocks of companies
 located in developed foreign countries. However, the Fund may invest up to
 25% of its assets in companies located or doing significant business, in
 emerging markets.
- ---------------------------------------------------------------
 
Q. HOW DID THE FUND PERFORM DURING THE PERIOD?
 
A. For the 12 months ended December 31, 1998, the Fund's total return was 9.47%
(Class A shares at NAV).(1) In comparison, the MSCI EAFE Index rose 20.33%.
 
Q. WHAT FACTORS AFFECTED YOUR PERFORMANCE?
 
A. Financial markets in 1998 were highlighted by record-high stock prices, as
well as by financial crises, unprecedented corporate consolidation and the dawn
of the European Monetary Union.
 
Mergers, acquisitions and restructuring drove many equity markets to all-time
highs in July. However, the Russian government's default on its debt, coupled
with a devaluation of the ruble, triggered margin calls on leveraged investments
throughout the world. This sharp sell-off caused a ripple effect of additional
margin calls, and forced sales of liquid assets that destabilized both emerging
and developed markets. The financial collapse of the Long-Term Capital
Management hedge fund, along with a rash of corporate profit warnings, further
damaged investors' faith in the markets.
 
However, three successive rate cuts by the U.S. Federal Reserve Board, and a
coordinated Europe-wide rate cut, restored stability. Corporate activity
resumed, and investors returned, sending international equity markets up more
than 20% during the fourth quarter. Our Fund participated in this rally to
finish up the year solidly.
 
Q. HOW DIVERSIFIED WAS THE FUND ACROSS THE WORLD'S MARKETS?
 
A. One significant advantage the Fund offers shareholders is the opportunity to
invest in many countries, sectors and individual companies, with a single
investment vehicle.
 
As of December 31, 1998, approximately 22.2% of the Fund's portfolio were
invested in the United Kingdom, 15.8% in France, 16.0% in Japan, 8.3% in
Germany, 7.4% in Sweden, 7.4% in Switzerland, 6.0% in Spain, 6.2% in Italy and
3.0% in the Netherlands. Our remaining assets were invested in Australia,
Denmark, Finland, Hong Kong, Singapore and Malaysia.*
 
The Fund's top five holdings were Vivendi (3.0% of the Fund's net assets),
British Aerospace PLC (2.7%), Allied Zurich AG (2.7%), Telefonica de Espana
(2.4%) and Telecom Italia SpA (2.3%).*
 
Q. WHAT IS YOUR OUTLOOK FOR 1999?
 
A. Many economies throughout the world, especially those of Russia and most
Asian and South American countries, continue to be roiled by uncertainty and
crisis. In developed nations, competitive pressures on margins should continue
in 1999. Top-line revenues may not be secure, as pricing power could be nearly
nonexistent and the global outlook could remain uncertain.
 
With the advent of the new European Monetary Union, which began January 1, 1999,
the trend toward mergers and restructurings should continue. The
mergers-and-acquisitions activity we have seen in the United States and Europe
may be joined by more of the same in Asia and Latin America if the economies in
these regions can stabilize and attract foreign capital. Although the financial
crises of the last two years suggest that caution would be prudent, we feel that
investment opportunities could arise as select companies take action to improve
their financial productivity.

The charts above represent a comparison of a hypothetical $10,000 investment in
the indicated share class versus a similar investment in the Fund's benchmark.
 
The quoted returns reflect the performance from 8/15/97 to 12/14/98 of the DG
International Equity Fund, an open-end investment company that was the
predecessor fund to the ISG International Equity Fund.
 
The Institutional Share class was initially offered on 12/14/98 and reflects the
historical performance of the Class A Shares (without sales charge) prior to
that date.
 
The Fund's performance is compared to the MSCI EAFE Index, which is unmanaged
and is generally representative of the performance of stock markets in those
regions. The index is unmanaged and does not reflect the expenses associated
with a mutual fund, such as investment management and fund accounting fees. The
Fund's performance reflects the deduction of fees for these value-added
services.
 
PAST PERFORMANCE IS NOT A PREDICTION OF FUTURE RESULTS. THE FUND'S INVESTMENT
RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL PURCHASE PRICE.

     The Funds are authorized to issue three classes of shares as follows:

(formerly known as the Investor Shares) and Class B Shares (except for the
Treasury Money Market Fund which does not offer Class B Shares and the Limited
Term Tennessee Tax-Exempt Fund which does not currently offer Institutional
Shares). At December 31, 1998, the Government Income Fund, the Municipal Income
Fund and the International Equity Fund had no Class B shares outstanding and
therefore no operations for such shares are shown. Class A Shares are subject to
an initial sales charge imposed at the time of purchase and Class B Shares are
subject to a contingent deferred sales charge at the time of redemption, as
described in the Funds' prospectus. Class A and Class B Shares bear distribution
(12b-1) fees (except for the Government Income Fund, the Municipal Income Fund,
the Large-Cap Equity Fund, the Small-Cap Opportunity Fund and International
Equity Fund, which did not bear 12b-1 fees until January 1, 1999). Class B
Shares bear shareholder servicing fees. Class A and Institutional Shares bear
shareholder servicing fees (except for the Limited Term U.S. Government Fund,
the Limited Term Tennessee Tax-Exempt Fund, the Tennessee Tax-Exempt Fund, the
Limited Term Income Fund, the Income Fund, The Equity Income Fund and the
Capital Growth Fund, which did not bear shareholder servicing fees until January
1, 1999). Each class has identical rights and privileges except with respect to
the distribution (12b-1) fees paid by Class A and Class B Shares, the
shareholder servicing fees paid by each respective class, voting matters
affecting a single class of shares and the exchange privileges of each class of
shares.
 
     At December 31, 1998, there were 25 billion shares of the Funds' $0.001 par
value common stock authorized, of which each Fund's shares are classified into
Class A Shares, Class B Shares and Institutional Shares.

for shares of the ISG Fund. Each DG Fund listed below transferred all of its
assets and liabilities to the corresponding ISG Fund identified opposite its

NOTE 4 -- SIGNIFICANT ACCOUNTING POLICIES
 
     The following is a summary of significant accounting policies followed by
the Funds in preparation of their financial statements. The policies are in
conformity with generally accepted accounting principles (GAAP). 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 Funds' 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.
 
     The Variable Net Asset Value Funds' 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. Investments in foreign securities of the International Equity Fund
are valued based on quotations from the primary market in which they are traded.
Investment companies are valued at the published net asset value per share. Debt
securities with remaining maturities of 60 days or less are normally valued at
amortized cost, which approximates market value. 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. The
differences between cost and market values of such investments are reflected as
unrealized appreciation or depreciation.

                               DECEMBER 31, 1998
 
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 (when applicable), is accrued daily. Dividend income is recorded on
the ex-dividend date.
 
C)  Repurchase Agreements:
 
     The Funds may invest in repurchase agreements from financial institutions,
such as banks and broker-dealers approved by the Board of Directors. The Funds'
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 Funds 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. Accordingly, the Funds could
receive less than the carrying value upon the sale of the underlying collateral
securities.
 
D)  Securities Purchased on a When-Issued Basis:
 
     Each Fund may purchase securities on a "when-issued" basis. When-issued
securities are securities purchased for delivery beyond the normal settlement
date at a stated price and/or yield, thereby, involving the risk that the price
and/or yield obtained may be more or less than those available in the market
when delivery takes place. At the time a Fund makes the commitment to purchase a
security on a when-issued basis, the Fund records the transaction and reflects
the value of the security in determining net asset value. Normally, the
settlement date occurs within one month of the purchase. A segregated account is
established and the Funds maintain cash and marketable securities at least equal
in value to commitments for when-issued securities. Securities purchased on a
when-issued basis do not earn income until settlement date.
 
E)  Foreign Currency Translation:
 
     The market value of investment securities, other assets and liabilities of
the International Equity Fund denominated in a foreign currency are translated
into U.S. dollars at the current exchange rate. Purchases and sales of
securities, income receipts and expense payments are translated into U.S.
dollars at the exchange rate on the dates of the 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 gains or losses
from investments.
 
     Reported net realized foreign exchange gains or losses arise from sales and
maturities of fund securities, sales of foreign currencies, currency exchange
fluctuations between the trade and settlement dates of securities transactions,
and the difference between the amounts of assets and liabilities recorded and
the U.S. dollar equivalent of the amounts actually received or paid. Net
unrealized foreign exchange gains and losses arise from changes in the value of
assets and liabilities, including investments in securities, resulting from
changes in currency exchange rates.
 
F)  Risks Associated with Foreign Securities and Currencies:
 
     Investments in securities of foreign issuers carry certain risks not
ordinarily associated with investments in securities of domestic issuers. Such
risks include future political and economic developments, and the possible
imposition of exchange controls or other foreign governmental laws and
restrictions. In addition, with respect to certain countries, there is the
possibility of expropriation of assets, confiscatory taxation, political or
social instability or diplomatic developments which could adversely affect
investments in those countries.

                               DECEMBER 31, 1998
 
     Certain countries may also impose substantial restrictions on investments
in their capital markets by foreign entities, including restrictions on
investments in issuers or industries deemed sensitive to relevant national
interests. These factors may limit the investment opportunities available to the
International Equity Fund or result in a lack of liquidity and high price
volatility with respect to securities of issuers from developing countries.
 
G)  Forward Currency Contracts:
 
     The International Equity Fund may enter into a forward currency contract
("forward") which is an agreement between two parties to buy and sell a currency
at a set price on a future date. The market value of the forward fluctuates with
changes in currency exchange rates. The forward is marked-to-market daily and
the change in market value is recorded by the Fund as unrealized appreciation or
depreciation. When the forward is closed, the Fund records a realized gain or
loss equal to the difference between the value at the time it was opened and the
value at the time it was closed. The Fund could be exposed to risk if a
counterparty is unable to meet the terms of a forward or if the value of the
currency changes unfavorably.
 
     Forwards may involve market or credit risk in excess of the amounts
reflected on the Fund's statement of assets and liabilities. The gain or loss
from the difference between the cost of original contracts and the amount
realized upon the closing of such contracts is included in net realized
gains/losses from investment and foreign currency transactions. Fluctuations in
the value of forwards held are recorded for financial reporting purposes as
unrealized gains and losses by the Fund. There were no forwards open at December
31, 1998.
 
H)  Securities Lending:
 
     To generate additional income, the Funds may lend up to 33 1/3% of
securities in which they are invested pursuant to agreements requiring that the
loan be continuously secured by cash, U.S. government or U.S. government agency
securities, shares of an investment trust or mutual fund, or any combination of
cash and such securities as collateral equal at all times to at least 100% of
the market value plus accrued interest on the securities lent. The Funds
continue to earn interest and dividends on securities lent while simultaneously
seeking to earn interest on the investment of collateral.
 
     When cash is received as collateral for securities loaned, the Funds may
invest such cash in short-term U.S. government securities, repurchase
agreements, or other short-term corporate securities. The cash or subsequent
short-term investments are recorded as assets of the Funds, offset by a
corresponding liability to repay the cash at the termination of the loan. In
addition, the short-term securities purchased with the cash collateral are
included in the accompanying schedules of portfolio investments. Fixed income
securities received as collateral are not recorded as an asset or liability of
the Fund because the Fund does not have effective control of such securities.
 
     There may be risks of delay in recovery of the securities or even loss of
rights in the collateral should the borrower of the securities fail financially.
However, loans will be made only to borrowers deemed by the adviser to be of
good standing and creditworthy under guidelines established by the Board of
Directors and when, in the judgment of the adviser, the consideration which can
be earned currently from such securities loans justifies the attendant risks.
Loans are subject to termination by the Funds or the borrower at any time, and
are, therefore, not considered to be illiquid investments. According to GAAP, a
statement of cash flows is presented if the Fund lent out, on average, more than
10% of net assets during the year. Under this guideline, a statement of cash
flows is presented for the Equity Income Fund and Capital Growth Fund. As of
December 31, 1998, the following Funds had securities with the following market
values on loan:

     The loaned securities were fully collateralized by cash which was invested
in U.S. government securities, commercial paper and repurchase agreements at
December 31, 1998.
 
I)  Expenses:
 
     The Funds 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 Funds account separately for the assets, liabilities and operations of
each Fund. Direct expenses of a Fund are charged to that Fund while general Fund
or Company expenses are allocated among the ISG Funds and the Company's other
series based on the relative net assets of each Fund and series.
 
J)  Federal Income Taxes:
 
     For federal income tax purposes, each Fund 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
Fund to meet the requirements of the Code applicable to regulated investment
companies, including the requirement that they distribute substantially all of
their income and capital gains to shareholders. Therefore, no federal income tax
provision is required.
 
     For federal income tax purposes, the following Funds have capital loss
carryovers as of December 31, 1998, which are available to offset future capital
gains, if any, on securities transactions to the extent provided for in the
Code:

K)  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 Treasury Money
Market Fund, Prime Money Market Fund, Limited Term U.S. Government Fund, Limited
Term Tennessee Tax-Exempt Fund, Tennessee Tax-Exempt Fund, Limited Term Income
Fund and Income Fund. Dividends are declared and paid monthly for the Government
Income Fund, Municipal Income Fund and Equity Income Fund. Dividends if, any,
are declared and paid quarterly for the Large-Cap Equity Fund, Capital Growth
Fund and Small-Cap Opportunity Fund. Dividends, if any, are declared and
distributed annually for International Equity Fund. For all Funds, distributions
of net realized gains, if any, will be paid at least annually.
 
     Dividends and distributions are recorded on the ex-dividend date.
Distributions from net investment income and from net realized gains are
determined in accordance with federal income tax regulations that may differ
from GAAP. These "book/tax" differences are either considered temporary or
permanent in nature. To the extent these differences are permanent in nature,
such amounts are reclassified within the composition of net assets based on
their federal tax-basis treatment; temporary differences do not require
reclassification.
 
     As of December 31, 1998, the following reclassifications have been made to
increase (decrease) such amounts with offsetting adjustments made to capital:

We conducted our audits in accordance with generally accepted auditing

reasonable assurance about whether the financial statements and 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. Our procedures included verification of securities owned as of
December 31, 1998, by confirmation with the custodian, correspondence with
brokers and other appropriate audit 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 financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the aforementioned funds comprising The Infinity Mutual Funds, Inc. -- ISG
Funds as of December 31, 1998, the results of their operations and their cash
