The Parkstone Group of Funds                                   December 31, 1997

Dear Shareholders:
 
While the markets experienced a few rocky moments during the six months ended
December 31, 1997, the period overall was a good one for investors in general
and for investors in the Parkstone Mutual Funds more specifically. Though
stocks took a dive in August, and then a breathtaking plunge in October, they
snapped back smartly from each within a matter of weeks. The bond markets, too,
gained ground as interest rates declined throughout the period--and as the
stock market grew more volatile, investors sought safety. Despite this
tumultuous environment, we are pleased to report that most of the Parkstone
Funds held their ground.
 
Moreover, investors' enthusiasm for stocks and bonds remained high. While not
at the breathtaking levels seen in 1996, money continued to stream into mutual
funds over the course of the period--and we're pleased to report that many of
these investors placed their confidence in the Parkstone Funds.
 
A TIME FOR CAUTION . . . AND OPTIMISM
 
Very simply, the past several years have been very good ones for stock
investors. But, much as we've said and expected for quite some time, the
markets have grown more volatile in recent weeks. As it has historically, the
law of gravity has begun to prevail. This, coupled with the crisis in Asia, has
created a very unpredictable environment. As a result, stocks have taken some
tumbles of late. In addition, they may take a few more in the months ahead,
before the situation sorts itself out and we see where different economies
around the world are headed.
 
Nevertheless, there is one thing we can be certain of: those who attempt to
second-guess the direction of the markets have seldom been as successful as
those who take a systematic, disciplined and long-term approach to investing.
That's why a long-term perspective is now more important then ever, yet more
difficult to maintain as the media headlines events in the financial markets
every night.
 
Nonetheless, now is a time to hold, not fold. In short, whatever happens in
Asia, we believe the U.S. financial markets are the strongest in the world--and
the best positioned to weather a storm. Historically, investors with the
fortitude to withstand the swings in price that such storms often bring have
been rewarded. And this may be the case this time as the fundamentals of our
economy are solid, and long-term prospects for U.S. corporations are bright.

The Parkstone Group of Funds                                   December 31, 1997

Dear Shareholders:
 
Historically, there is nothing the financial markets have hated quite as much
as uncertainty--and as we begin the New Year, there is certainly plenty to go
around. Worries about the impact of the turmoil in Asia, and about the
direction of U.S. interest rates and inflation, dominate the headlines. New
rumors about corporate profits surface hourly, and experts speculate as to how
long the investor psychology that fueled the spectacular growth of the mutual
fund industry--and, in turn, the stock market--can last.
 
The truth is, no matter how long each of these subjects is dissected or
debated, no one can foresee the future. It is clear, however, that in three of
the five world economic regions, economic growth is likely to remain at last
year's level or to expand more slowly than in 1997. Demand from these regions,
in particular Asia, have underpinned U.S. export growth over the past several
years. Therefore, our economy--already slowing--may slow further, but just how
much or for how long is impossible to predict precisely.
 
THE ASIAN FLU
 
Much of the uncertainty now, of course, is due to the situation in Asia. After
almost a decade of explosive growth, there is now substantially more production
capacity than there is worldwide demand for many products produced in Asia. Due
to the shaky state of financial institutions in the region, local consumers
find it difficult, if not impossible, to get credit, as do local businesses
that need credit to finance their operations. Galloping to the rescue, the
International Monetary Fund has presented a series of plans designed to
stabilize the stricken economies. Within the region, however, the preferred
solution seems to be to increase exports to the United States--where benevolent
American consumers will save Asia with their purchases.
 
However, U.S. consumers are unlikely to desire anything near the quantity of
goods likely to be forthcoming. Moreover, because their Asian trading partners
have less need for industrial inputs and their foreign consumers are no longer
in the position to purchase their products, U.S. corporations are likely to
find their own exports slowing, and, in some cases, even declining. Corporate
profits, of course, will be impacted--but keep in mind that over 50% of the
U.S. economy is service oriented. Many of the services provided by individuals
are unaffected by overseas pricing.
 
Nonetheless, events in Asia will have an impact this year and perhaps for the
next several years. This year, we believe our economy will grow at a rate of
2.5%, with corporate profits increasing about 6% or so. Both numbers are
smaller than those we have seen in the past several years--but we believe they
will still be increasing.
 
WHAT ABOUT THE MARKETS?
 
In recent weeks, U.S. interest rates have declined more than most experts in
the marketplace anticipated--and many pundits are projecting long-term rates
may go as low as 5%. While this has sparked more enthusiasm for bonds than we
have seen in several years, rates significantly below 5.5% are unlikely to be
sustained over the course of the year. At this point, however, the interest
rate decline has been critical to the stock market, where earnings estimates
are being reduced. Why? Because the interest rate declines help maintain the
current price/earnings ratio in the stock market, or increase it slightly,
which offsets any earnings decline.
 
This does not make for a buoyant stock market, but on the other hand, it
forestalls another serious correction. Moreover, it could provide a foundation
for further gains if there is positive economic news--particularly in the first
half of the year. Much, however, will depend on market psychology, which was
extremely favorable until the Asian mania reached its current level. Sentiment
now appears to be moving to a more neutral position--and could become negative,
depending on the severity of the effects the Asian Flu has on the U.S. economy.

IN ADDITION, THERE ARE A FEW WILD CARDS
 
Finally, based on the events of the past year, the Fed is now likely to
consider easing rather than increasing interest rates, which would help if the
environment grows less favorable. Also, we cannot lose sight of the fact that
1998 is a year of congressional elections. Typically, in an off-year election,
the opposition--in this case, the Republicans--will pick up additional seats in
Congress. We expect these elections to have little impact, but months of heated
rhetoric about spending lie ahead of us. Moreover, in politics, just like in
the financial markets, things can change in the wink of an eye.

The Parkstone Group of Funds                                   December 31, 1997

                          SMALL CAPITALIZATION FUND+

Ironically, the six months ended December 31, 1997, were the best of times and
the worst of times for growth-oriented small-cap companies and their investors.
A strong economy, benign inflation and declining interest rates created an
environment where many saw their earnings and revenues soar. Yet, investors
concerned with events overseas and the direction of interest rates continued to
overlook and undervalue small-capitalization companies in favor of large-caps.
Consequently, stock prices in the sector remained stable or even declined.
 
Nevertheless, some of our holdings made progress that was simply too
astonishing to ignore--and therefore, their stock prices did rise dramatically.
Pacific Gateway (2.0% of the portfolio's assets), an international telephone
company, climbed 90% over the six months. Despite bright spots like this,
however, the period overall was a discouraging one for growth-oriented small-
cap investors. For the six months ended December 31, 1997, the Fund produced a
total return of -2.17% (Investor A Shares).*
 
THE SPOTLIGHT WILL SHIFT
Despite current market sentiment, we remain very optimistic about the prospects
of growth-oriented small-cap stocks in general, and for our holdings in
particular. Out-of-favor now for more than two years, many of these companies
are growing at a rate three times faster than the market overall. Regarding our
holdings specifically, we anticipate that, on average, the companies held have
the potential to show a 40% gain in earnings in 1998 over 1997. Inevitably,
market sentiment could change--and when it does, we believe the Fund is very
well positioned to participate in the sector's comeback.
 
As of December 31, 1997, the top five holdings in the Fund's portfolio were
Dura Pharmaceuticals, Inc. (3.9%), Sanmina Corp. (3.6%), Rexall Sundown, Inc.
(2.8%), Veritas Software Corp. (2.6%) and Visio Corp. (2.6%).**
- -------
+  Small-cap funds typically carry additional risks since smaller companies
generally have a higher risk of failure. Historically, stocks of smaller
companies have experienced a greater degree of market volatility than stocks on
average.
*  The total return, with the maximum 4.50% sales charge, was - 6.58% for the
period.
** The Portfolio's composition is subject to change.

The Fund's performance is being compared to the Russell 2000 Stock Index, which
represents the performance of domestically traded common stocks of small to
mid-sized companies. The index is unmanaged and does not reflect the deduction
of fees associated with a mutual fund, such as investment management and fund
accounting fees. The performance of the Parkstone Small Capitalization Fund
reflects the deduction of fees for these value-added services. Past performance
is not indicative of future results. The investment return and NAV will
fluctuate, so that an investor's shares, when redeemed, may be worth more or
less than their original cost.

The Parkstone Group of Funds                                   December 31, 1997

                            MID CAPITALIZATION FUND

Turmoil in Asia and declining interest rates created an atmosphere of
uncertainty in the equity markets during the six months ended December 31,
1997. Given the volatile environment, investors sought liquidity, and,
therefore, preferred the largest and best-known names. The vast majority of
mid-cap and small-cap stocks--no matter how strong their fundamentals and lack
of international exposure--were simply left standing on the sidelines. In
addition, what little interest there was in the sectors favored value stocks
over growth.
 
As the year ended, however, the quality of some of the Fund's holdings
attracted attention. In the fourth quarter alone, Chancellor Media (2.40% of
the portfolio's assets) rose 42%, and Paychex (2.66%) gained 29%. Despite this,
performance was somewhat disappointing, due to the lackluster environment for
mid-cap and small-cap growth stocks. For the six months ended December 31,
1997, the Fund posted a total return of 9.04% (Investor A Shares).*
 
OVERLOOKED AND UNDERVALUED
Clearly, events have trended in favor of larger capitalization stocks over the
past year. First, as the stock market continued to rocket upwards, investors
sought safety. Then, as events in Asia unfolded, liquidity concerns dominated.
Therefore, despite the fact that many smaller and mid-capitalization companies
have little or no international exposure, they have been overlooked for more
than a year. In that time, many have experienced astonishing growth--and yet
their stock prices have remained stable or fallen.
 
Consequently, many truly outstanding opportunities abound--particularly in
healthcare, consumer stocks and selected areas of technology. Long term, their
growth prospects are very, very strong. At some point, the sheer strength of
these companies' fundamentals will draw investor interest again. Therefore, we
are making every effort to capitalize on the bargains available--and we are
very optimistic about the Fund's long-term prospects.
 
As of December 31, 1997, the top five holdings in the Fund's portfolio were
Service Corp. International (3.3%), Peoplesoft (3.2%), Cardinal Health (2.7%),
Health Management Associates (2.6%) and Paychex, Inc. (2.6%).**

                           LARGE CAPITALIZATION FUND

Large-capitalization stocks benefited from market sentiment in the six months
ended December 31, 1997. As interest rates fell and troubles increased in Asia,
investors sought quality and liquidity. In general, the biggest and best-known
names were popular, but more specifically, large-cap utility companies and
banks were the belles of the ball. Given the fact that these companies do not
offer investors much growth potential, our portfolio was underweighted in these
particular sectors.
 
Nevertheless, the Fund performed very well, as holdings in other sectors made
substantial contributions to performance. Among the strongest performers were
Pfizer (2.76% of the portfolio's assets), which gained 30% over the course of
the six months, and PeopleSoft (1.60%), which rose 30% in the fourth quarter
alone. Walgreen's (1.70%) and Automatic Data Processing (1.21%) also climbed
over 20% in the fourth quarter. Having no exposure in Asia, the Fund performed
well and posted a total return of 8.68% (Investor A Shares)* for the six months
ended December 31, 1997.
 
A VOLATILE ENVIRONMENT
Clearly, concerns over the impact of events in Asia on our economy and on U.S.
corporations is not likely to be alleviated any time soon. Consequently, we
expect that the market will remain very sensitive to conditions there--and any
earnings disappointments domestically--for some time to come. In such an
environment, liquidity and quality may continue to be paramount to investors.
 
Nevertheless, the U.S. economy remains healthy, with little evidence of
inflation. Interest rates are declining. In short, the foundation for future
earnings growth is in place. Therefore, we are optimistic about the long-term
prospects for the stock markets in general, and for our holdings in particular.
We would continue to see any major correction as a buying opportunity.
 
As of December 31, 1997, the top five holdings in the Fund's portfolio were
Cendant Corp. (2.9%), Pfizer, Inc. (2.8%), Cisco Systems (2.75), Eli Lilly &
Co. (2.6%) and Procter & Gamble Co. (2.5%).**

*  The total return, with the maximum 4.50% sales charge, was 3.80% for the
period.

                         INTERNATIONAL DISCOVERY FUND+

Asian markets collapsed in 1997, as what began as a ripple in February, when a
small property company in Thailand missed a payment on its foreign debt,
developed into a tidal wave of bankruptcies and currency devaluations
throughout the region by August. By late in the fourth quarter, investors in
Europe and North America were beginning to realize the severity of the economic
devastation in Asia, and the potential negative impact it might have on
corporate earnings in their home markets. Old-fashioned panic was in evidence
several days over the last three months, in London and New York as well as in
Tokyo and Hong Kong, as global stock markets suffered dramatic day-to-day
volatility.
 
Currencies also had a major impact on investment performance over the course of
the period, as the continued strength of the U.S. dollar significantly reduced
investment returns for U.S. based investors. Consequently, the combination of
declining Asian markets and weak currencies worked to produce a somewhat
disappointing return of -8.14% (Investor A Shares).*
 
LOOKING BEYOND ASIA
Going forward, 1998 promises to be a year of increased uncertainty, as the
Asian financial collapse will have a detrimental influence on foreign trade,
economic growth and corporate profits around the globe. The depth and longevity
of the global slowdown is dependent on the ability of the Asian countries to
put their houses in order and embark on sustainable growth trends. We are not
willing to believe the bottom in the smaller Asian markets has been reached
until we see evidence of currency stabilization and movements toward economic
restructuring in each of these countries. At the present time, such
developments are lacking.
 
Europe and Latin America, on the other hand, continue to offer strong
investment opportunities. Even though reduced exports to Asia will have a minor
negative impact on GDP strong consumer demand and low interest rates continue
to produce a favorable investment environment for continental Europe. The
developing economies of Latin America, although not immune from the troubles
occurring across the Pacific, have already experienced most of the problems
afflicting the Asian Tigers and appear to be better positioned to maintain
their underlying growth paths.
 
UNEARTHING OPPORTUNITY
The year 1998 begins with many more concerns about the global investment
outlook than prior years, but we believe this environment of uncertainty
provides the opportunity for high-quality companies to display superior
operating performance in the months ahead. Those are the types of companies we
always invest in, and we look forward to the year with a high measure of
confidence.
 
As of December 31, 1997, the top five holdings in the Fund's portfolio were SAP
Preferred (2.93%), Takeda Chemical (2.42%), Adidas (2.26%), Rohm (2.19%) and

The Parkstone Group of Fund                                   Decembers 31, 1997

                          CONSERVATIVE ALLOCATION FUND

While the year was a tumultuous one in the financial markets, it was a good one
all in all for the Fund. After watching employment numbers anxiously throughout
the spring, investors were finally convinced that inflation was not a problem.
Interest rates began to decline. Bonds gained ground throughout the summer. And
then, in the fall, on news of troubles in Asia, investors fled to safety and
quality--and large-cap stocks and high- quality fixed-income securities were
their investments of choice.
 
With sizable exposures in each of these sectors throughout the period, the Fund
was well-positioned to benefit, and did. Our portfolio, however, also held
positions in mid-capitalization stocks, which were trampled underfoot as
investors moved en masse to the larger cap sector over the course of the year.
Consequently, the Fund slightly lagged its industry averages. For the six
months ended December 31, 1997, the Fund produced a total return of 5.66%
(Institutional Shares), versus a return of 33.36% for the S&P 500 and a return
of 9.62% for the Salomon Brothers Broad Index.
 
A CAUTIOUSLY OPTIMISTIC OUTLOOK
We expect the months ahead to be good ones for the Fund. While we expect to see
some slowing in the coming year, our economy is growing and inflation is under
control. In short, the fundamentals are very strong--which may put further
downward pressure on interest rates. All of which provides a very solid
foundation for stocks, and may create an even more positive environment for
fixed-income investments in the months ahead. Consequently, while we will
approach cautiously, we are optimistic about prospects for the financial
markets in the months ahead.
 
As of December 31, 1997, approximately 27% of the fund's assets were invested
in stocks, 67% in bonds and notes with the remaining 6% held in cash or cash
equivalents. The fixed-income portion of the portfolio was widely diversified,
with exposures in corporate bonds, and mortgage-related and asset-backed
securities, as well as Treasury securities. The average maturity of these
holdings was 9.1 years. The top five holdings in the equity portion of the
portfolio were Peoplesoft (0.08%), Service Corp. Int'l (0.6%), Cardinal Health
(0.6%), SunAmerica, Inc. (0.6%) and Cendant Corp. (0.5%).*

The Parkstone Group of Funds                                   December 31, 1997

                            BALANCED ALLOCATION FUND

Despite the fact that the eventual impact of the Asian Flu on U.S. corporations
was unclear, investors sought the safety and quality of large-cap stocks in the
six months ended December 31, 1997. Over the course of the period, the 50
biggest U.S. stocks performed well, and international, mid-cap and small-cap
stocks--regardless of fundamental strength or growth prospects--were left
behind.
 
At the same time, declining interest rates and increased investor interest in
high-quality instruments sparked a rally in the fixed-income markets. However,
while bonds posted a solid return, they, too, lagged the S&P 500. In short,
with stock market sentiment so narrowly focused throughout the period, the
performance of widely diversified portfolios suffered--and ours was no
exception. For the six months ended December 31, 1997, the Fund produced a
total return of 4.62% (Investor A Shares). *
 
THE TIDE WILL TURN
 
Despite the events of the past several months, it is unrealistic to believe
that the market's infatuation with larger capitalization stocks will last
forever. Valuations in the sector are very high in comparison to small- and
mid-capitalization stocks. On a risk-adjusted basis, bonds, too, look very
attractive. In recent weeks, there has been evidence that investors are
beginning to recognize the values that exist in these sectors--and we expect to
see this trend accelerate as our economy slows. Therefore, we are optimistic
about the Fund's prospects in the months ahead.
 
As of December 31, 1997, approximately 48% of the fund's assets were invested
in stocks, 45% in bonds and the remaining 7% was held in cash or cash
equivalents. The fixed-income portion of the portfolio was widely diversified,
with exposures in corporate bonds, and mortgage-related and asset-backed
securities, as well as Treasury securities. The average maturity of these
holdings was 9.1 years. The top five holdings in the equity portion of the
portfolio were Peoplesoft (0.8%), Sun America, Inc. (0.7%), Service Corp.
International (0.7%), Cardinal Health (0.6%) and Dura Pharmaceuticals (0.6%).**

                           AGGRESSIVE ALLOCATION FUND

As the market roared to record levels in the first half of the year ended
December 31, 1997, investors sought the safety of big names. Then, as interest
rates plummeted and trouble arose in Asian currency markets, liquidity concerns
dominated. As a result, international, small-cap and mid-cap stocks--regardless
of their fundamental strength--wilted from neglect.
 
Throughout much of the period, approximately 67% of the Fund's assets were
invested in equities. While some of these holdings were invested in large-cap
companies, the portfolio also held a number of small- and mid-cap companies--as
well as a sizable component of international stocks. Consequently, because
market sentiment was so narrowly focused throughout the period, performance
suffered. For the year ended December 31, 1997, the Fund produced a total
return of 3.73% (Institutional Shares)*.
 
THE LONG-TERM PERSPECTIVE
Despite the events of the past several months, its unrealistic to believe that
the market's infatuation with larger capitalization stocks will last forever.
Valuations in the sector are very high in comparison to small- and mid-
capitalization stocks. In recent weeks, there's been evidence that investors
are beginning to recognize the values that exist in these sectors--and we
expect to see this trend accelerate as our economy slows. Moreover, as every
crises does, the troubles in Asia will produce a number of opportunities.
 
Consequently, we are optimistic about the Fund's prospects in the months ahead
and more committed than ever to a balanced approach to the marketplace.
Historically, such a strategy has helped to reduce volatility and increase the
potential for growth--and we have no reason to believe that this won't be the
case in the coming years.
 
As of December 31, 1997, approximately 66% of the fund's assets were invested
in stocks, 28% in bonds and the remaining 6% were held in cash or cash
equivalents. The fixed-income portion of the portfolio was widely diversified,
with exposures in corporate bonds, mortgage-related and asset-backed securities
as well as Treasury securities. The average maturity of these holdings was 9.1
years. The top five holdings in the equity portion of the portfolio were
Peoplesoft (1.1%), SunAmerica, Inc. (0.9%), Cardinal Health (0.9%), Service
Corp. Int'l (0.9%) and Dura Pharmaceuticals (0.8%).*

                               EQUITY INCOME FUND

\igh-quality, dividend-paying stocks were very popular during the six months
ended December 31, 1997. With interest rates declining and Asian financial
markets in trouble, investors sought safety. Financial services, utility and
energy stocks did particularly well in this environment. Heavily weighted in
these areas, the Fund benefited and produced a total return of 8.43% (Investor
A Shares) for the six months ended December 31, 1997.*
 
Among the strongest performers of the portfolio were its holdings in financial
services. Over the course of 1997, PNC (2.02%), First Tennessee (2.21%) and
Allstate Insurance (1.16%) all posted gains over 20%. Pharmaceuticals,
utilities and energy stocks also made solid contributions over the six months
and over the course of 1997.
 
INTERESTING TIMES AHEAD
With the situation in Asia still unraveling and investors unclear as to what
this means for the U.S. economy, we expect the year ahead to be a volatile one
for the stock market. At the same time, however, the U.S. economy remains
fundamentally sound; inflation is benign; and interest rates are declining.
 
Yes, the situation in Asia is worrisome. However, it is important to note that
while we do have holdings in the financial sector, most are smaller,
domestically oriented financial services companies unlikely to feel much impact
from any currency crises. The same holds true for our exposures in utilities,
consumer staples, retailing and health care. While our holdings in drug and oil
companies are somewhat more vulnerable, the Fund is not overweighted in either
area. Therefore, while the ride may be a little rockier than in the past, we
remain very optimistic about the Fund's prospects in the months ahead.
 
As of December 31, 1997, the top five holdings in the Fund's portfolio were
Bristol Myers Squibb Co. (3.5%), Eli Lilly & Co. (3.3%), JC Penney Co. (3.1%),
MBNA (3.1%) and Flowers Industries (3.1%).**

* The total return, with the maximum 4.50% sales charge, was 3.58% for the
period.
** The portfolio's composition is subject to change.

                             THE FIXED INCOME FUNDS
 
After playing second fiddle to stocks for several years, the bond markets took
center stage as sentiment shifted in the six months ended December 31, 1997.
Benign inflation, a growing economy and the prospect of the first federal
budget surplus in decades caused rates to drift downward throughout the summer
and early fall. Then, in October, with the stock market growing more volatile,
and word of the currency crisis in Asia, investors sought quality and safety.
Long-term interest rates moved decisively lower. Fixed-income securities across
the spectrum benefited--but, given investors' concerns, the high-quality
securities, particularly mortgaged-backed securities, were among the most
popular.
 
We expect the months ahead to be good ones for the bond markets. As events have
unfolded in Asia, it has become clear that the situation will take some time to
play itself out. While it is unclear just how the U.S. economy will be
impacted, it is apparent that we will see some slowing of growth. This would
put further downward pressure on rates--and create a very attractive
environment for bonds.
 
Regardless of our optimism, however, we expect to approach the marketplace
cautiously in the months ahead. In a declining environment, prepayment risk
historically has risen significantly--and given the technological advances of
the past several years, refinancing is a much more efficient and rapid process
today. Consequently, while the mortgage-backed sector did particularly well
over the past several months, prepayment risk may rise dramatically if rates
drop lower. In short, careful security selection will be critical to success in
the months ahead.
 
BOND FUND
Throughout the six months ended December 31, 1997, the Fund was positioned
conservatively. Despite the fact that mortgage-backed securities were
performing strongly, the Fund was underweighted in the sector. This was simply
because these securities did not represent good value on a fundamental basis--
as interest rates fell, little or no compensation was offered for growing
prepayment risk.
 
At the same time, however, as news of troubles in Asia reached the fixed-income
market, spreads widened in the corporate markets--and we seized a number of
very attractive opportunities there as the year ended. Therefore, for the six
months ended December 31, 1997, the Fund produced a total return of 5.93%
(Investor A Shares).*
 
As of December 31, 1997, approximately 60% of the Fund's assets were invested
in corporate bonds, 27% in mortgage-backed and asset-backed securities, and 7%
in U.S. Treasuries, with the remainder invested in agency-backed securities. As
of the same date, the average credit quality of the portfolio was Aaa; the
average maturity was 11.4 years.** Barring a significant change in the market
environment, no major changes are anticipated in the portfolio's allocation,
maturity or credit structures in the months ahead.

* The total return, with the maximum 4.00% sales charge, was 1.73% for the
period.
** The Portfolio's composition is subject to change.

The Fund's performance is being compared to the Salomon Brothers Broad Index,
which represents the performance of the overall bond market. The index is
unmanaged and does not reflect the deduction of fees associated with a mutual
fund, such as investment management and fund accounting fees. The performance
of the Parkstone Bond Fund reflects the deduction of fees for these value-added
services.
 
Past performance is not indicative of future results. The investment return and
NAV will fluctuate, so that an investor's shares, when redeemed, may be worth
more or less than their original cost.

The Parkstone Group of Funds                                   December 31, 1997


                           LIMITED MATURITY BOND FUND

Designed to provide investors with low volatility and higher returns than money
market funds, the Fund did its job well during the six months ended December
31, 1997. Invested primarily in corporate bonds and asset-backed securities,
the portfolio produced a total return of 2.99% (Investor A Shares)* for the
period.
 
Looking ahead, while we are optimistic about the prospects for the fixed-income
markets, opportunities in the shorter end of the curve may not be as plentiful
as in the longer end. Nevertheless, as the year drew to a close, corporate
securities performed very well, as balance sheets continued to strengthen, and
offered investors solid opportunities. At that time, we capitalized on several
corporate issues, and in the months ahead, we would hope to add further to our
weighting in the sector.
 
As of December 31, 1997, approximately 40% of the Fund's assets were invested
in corporate bonds, 13% in asset-backed securities, and 32% in U.S. Treasuries,
with the remainder invested in U.S. agency securities and Cash Equivalents. As
of the same date, the average credit quality of the portfolio was Aaa; the
average maturity 2.6 years.**

The Parkstone Group of Funds                                   December 31, 1997

                    INTERMEDIATE GOVERNMENT OBLIGATIONS FUND

Invested primarily in Treasury bonds and mortgage-backed securities, the Fund
performed very well over the period, as investors fled to quality. For the six
months ended December 31, 1997, the portfolio produced a total return of 4.34%
(Investor A Shares)*.
 
Nonetheless, as interest rates moved gradually lower, prepayment risks moved
upward--regardless of the fact that investors seemed content to ignore this
throughout much of 1997. In the months ahead, should interest rates decline,
those risks can only be expected to grow greater. Moreover, given the speed and
efficiency with which borrowers can now refinance, a change in sentiment that
once took several months to impact the marketplace could now take place within
a matter of days.
 
Therefore, in the months ahead, we expect to approach the markets cautiously.
Exposure in the mortgage-backed sector may be gradually peeled back in favor of
Treasury securities. As of December 31, 1997, approximately 69% of the Fund's
assets were invested in U.S. Treasury securities, with the remainder invested
in agency-backed and mortgage-backed securities. As of the same date, the
average maturity of the Fund's holdings was 4.1 years. **

The Parkstone Group of Funds                                   December 31, 1997

                          U.S. GOVERNMENT INCOME FUND

Invested primarily in government-assisted mortgage loans ten or more years old,
the Fund benefited from investor interest in mortgage-backed securities over
the six months ended December 31, 1997. Unlike other funds of this type,
however, the average maturity of the holdings in the portfolio is in the
intermediate range--and the strongest performers in the mortgage-backed sector
were concentrated in the longer end of the curve. Nonetheless, the period was a
good one for the Fund, which produced a return of 5.04% (Investor A Shares).*
 
Looking ahead, we believe the next few months will be good ones for the Fund.
While increasing prepayment risk clouds the future for much of the mortgage-
backed sector, the Fund's holdings have proven to be relatively impervious to
the ups and downs of interest rates over the years. Certainly, if rates fall to
record lows, the Fund will experience some refunding.
 
As of December 31, 1997, approximately 78% of the Fund's assets were invested
in mortgage-backed securities and commercial mortgage obligations, and 22% in
U.S. Treasury and agency securities. As of the same date, the average duration
of the Fund's holdings was 2.83 years.**
 
- -----------------
*The total return, with the maximum 4.00% sales charge, was 0.85% for the
period.
**The Portfolio's composition is subject to change.

                           THE TAX-FREE INCOME FUNDS

Much like the taxable markets, the municipal markets reacted to each number and
statistic reported and all rumors circulated during the six months ended
December 31, 1997. Moreover, as troubles grew in Asia and investors fled to
safety and liquidity, sentiment favored Treasury securities. Markets across the
country weakened, and municipals underperformed Treasury securities over the
course of the period.
 
Looking ahead, there's little reason to believe that the markets will cease
running the gamut of emotion in response to events at home and abroad.
Nonetheless, we are optimistic about the long-term prospects for the municipal
markets. Recent weakness has created a number of very attractive opportunities.
In addition, recent volatility in the stock market has increased investor
interest in fixed-income securities. We expect to see their popularity grow in
the years ahead as baby boomers move closer to retirement and seek the tax
benefits municipals offer.
 
THE MUNICIPAL BOND FUND
Supply of new securities was steady in municipal markets across the country
during the six months ended December 31, 1997. Given the fact that insurance is
now relatively cheap, over fifty percent of the new issues coming to market
were insured. As a result, credit spreads narrowed as the premiums to assume
additional risk vanished. In short, even if you were a die-hard opportunist,
you would have had a hard time finding opportunity in the marketplace.
 
As always, we focused our efforts on intermediate-term, higher quality
securities and approached the markets cautiously. As a result, while the
environment was somewhat volatile due to the problems in Asia, the Fund kept
pace with its peers. For the six months ended December 31, 1997, it posted a
total return of 4.29% (Investor A Shares).*
 
Barring a dramatic shift in the environment, no major changes are anticipated
in the Fund's credit or maturity structure in the months ahead. As of December
31, 1997, the average maturity of assets in the Fund's portfolio was 7.43
years; the average credit quality was AA. Widely diversified, the portfolio
held securities issued by more than 32 municipalities as of the same date.**

* The total return, with the maximum 4.00% sales charge, was 0.11% for the
period.

                          MICHIGAN MUNICIPAL BOND FUND

Bond insurance was also prevalent on new issues in Michigan during the six
months ended December 31, 1997. With insurance, these bonds traded lower in
yield and offered investors little incentive to purchase. Moreover, supply in
the Michigan market continued to be somewhat tight. Therefore, opportunities
worth the chase were rare during the period. Despite the environment, however,
the Fund performed well and posted a return of 4.58% (Investor A Shares)*.
 
Looking ahead, we expect the supply of new issues to increase very soon, as
many school bond elections are scheduled for February and March. In addition,
the recent slide in long-term rates may prompt many municipalities to consider
refunding outstanding debt. At the very least, greater supply will increase
flexibility; at the most, it will create opportunity. Therefore, we are
optimistic about the Fund's prospects in the months ahead.
 
As of December 31, 1997, the average maturity of assets in the Fund's portfolio
was 8.07 years; the average credit quality was AA. No more than 5% of the
Fund's assets are invested in any one issue.**

The Fund's performance is being compared to the Lehman Brothers Mutual Fund
Intermediate Index, which represents the performance of municipal bonds in that
maturity range. The index is unmanaged and does not reflect the deduction of
fees associated with a mutual fund, such as investment management and fund
accounting fees. The performance of the Parkstone Michigan Municipal Bond Fund
reflects the deduction of fees for these value-added services.
 
Past performance is not indicative of future results. The investment return and
NAV will fluctuate, so that an investor's shares, when redeemed, may be worth
more or less than their original cost.

                            THE MONEY MARKET FUNDS

Looking at strong job growth numbers, investors expected interest rates to
rise as the six months ended December 31, 1997, opened. However, inflationary
pressure failed to materialize, and rates drifted slightly lower. Then, in
October, when indications of trouble in the Asian markets appeared, the money
markets grew more volatile. When all was said and done, however, short-term
rates moved up and down within a relatively narrow range during the period.
 
Looking ahead, it is clear that Asia's problems will not be solved overnight.
Nonetheless, the impact on the U.S. economy may be minimal. What is more, once
this is apparent, investors may again focus on job growth--and realize that
unemployment is at the lowest levels seen in decades. While we do not expect
to see interest rates rise significantly any time soon, inflation anxiety may
return in the very near future.
 
As a result, we expect to approach the marketplace very cautiously in the
months ahead. Maturities may be lengthened slightly when attractive
opportunities to do so arise. In recent months, however, such opportunities
have been rare, as spreads did not justify additional risk.
 
 . THE PRIME OBLIGATIONS FUND: As of December 31, 1997, approximately 83.7% of
the Fund's assets were invested in commercial paper, with the remainder
invested in overnight securities. The average maturity of the Fund's holdings
was 45 days.*
 
 . THE U.S. GOVERNMENT OBLIGATIONS FUND: As of December 31, 1997, the Fund's
assets were invested in overnight securities, as well as in short-term agency
and Treasury securities. The average maturity of the portfolio was 38 days.*
 
 . THE TREASURY FUND: Approximately 83.1% of the Fund's assets were held in
repurchase agreements as of December 31, 1997, and the average maturity of the
portfolio was 28 days.*
 
 . THE TAX-FREE FUND: As of December 31, 1997, the average maturity of assets
in the Fund's portfolio was 55 days. As of the same date, assets were invested
primarily in high-quality variable-demand notes, tax-exempt commercial paper
and short-term bonds.*

The Parkstone Group of Funds                                   December 31, 1997
                                                                     (Unaudited)


1. ORGANIZATION:
 
 The Parkstone Group of Funds (the "Group") was organized on July 9, 1987, and

 Government Obligations Fund is to seek current income with preservation of
 capital by investing in U.S. Government securities with remaining maturities
 of twelve years or less. The investment objective of the U.S. Government
 Income Fund is to provide shareholders with a high level of current income
 consistent with prudent investment risk. The investment objective of the Bond
 Fund is to seek current income as well as preservation of capital by

 interest income which is exempt from federal income taxes as well as
 preservation of capital. The investment objective of the Michigan Municipal
 Bond Fund is to seek income which is exempt from federal income tax and
 Michigan state income and intangibles tax when received by certain
 Shareholders, and to seek preservation of capital. The investment objective

 conservation of capital, with a secondary objective of long-term capital
 growth. The investment objective of the Balanced Allocation Fund is to seek
 current income, long-term capital growth and conservation of capital. The

The Parkstone Group of Funds                                   December 31, 1997
                                                                     (Unaudited)

 
 The Group has issued three classes of Fund shares in the Prime Obligations
 Fund: Investor A Shares, Investor B Shares, and Institutional Shares and two
 classes of Fund shares in each of the U.S. Government Obligations Fund, the
 Tax-Free Fund and the Treasury Fund (collectively, "the money market funds"):
 Investor A Shares and Institutional Shares. The Group has issued four classes
 of Fund shares in each of the Small Capitalization Fund, the Mid
 Capitalization Fund, the Large Capitalization Fund, the International
 Discovery Fund, the Limited Maturity Bond Fund, the Intermediate Government
 Obligations Fund, the U.S. Government Income Fund, the Bond Fund, the
 Municipal Bond Fund, the Michigan Municipal Bond Fund, the Balanced
 Allocation Fund and the Equity Income Fund: Investor A Shares, Investor B
 Shares, Investor C Shares and Institutional Shares. The Group has only
 offered Institutional Shares for the Conservative Allocation Fund and the
 Aggressive Allocation Fund. The group has issued five classes of fund shares
 in the Emerging Markets Fund: Investor A Shares, Investor B Shares, Investor
 C Shares, Institutional Shares, and Investor Z Shares. The Investor A Shares
 of the Funds other than money market funds (collectively, "the variable net
 asset value Funds") are subject to initial sales charges imposed at the time
 of purchase, in accordance with the Funds' prospectuses. Certain redemptions
 of Investor B Shares made within five years of purchase and Investor C Shares
 made within one year of purchase are subject to contingent deferred sales
 charges in accordance with the Funds' prospectuses. The Investor Z Shares of
 the Emerging Markets Fund shall be offered at the then-current net asset
 value without the imposition of a front-end or contingent deferred sales
 charge. Each class of shares for each Fund has identical rights and
 privileges except with respect to distribution (12b-1) fees paid by the
 Investor A Shares, Investor B Shares and Investor C Shares, voting rights on
 matters affecting a single class of shares and the exchange privileges of
 each class of shares.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
 The following is a summary of significant accounting policies followed by the
 Group in the preparation of its financial statements. The policies are in
 conformity with generally accepted accounting principles. The preparation of
 financial statements requires management to make estimates and assumptions
 that affect the reported amounts of assets and liabilities at the date of the
 financial statements and the reported amounts of income and expenses for the
 period. Actual results could differ from those estimates.
 
  SECURITIES VALUATION:
 
  Investments of the money market funds are valued at either amortized cost,
  which approximates market value, or at original cost, which combined with
  accrued interest approximates market value. Under the amortized cost
  method, discount or premium is accreted or amortized on a constant basis to
  the maturity of the security. In addition, the money market funds may not
  (a) purchase any instrument with a remaining maturity greater than thirteen
  months unless such instrument is subject to a demand feature, or (b)
  maintain a dollar-weighted average portfolio maturity which exceeds 90
  days.
 
  Investments in common and preferred stocks, corporate bonds, commercial
  paper, municipal and foreign government bonds and U.S. Government
  securities of the variable net asset value funds are valued at their market
  values determined on the basis of the mean between the latest available bid
  and asked prices in the principal market (closing sales prices if the
  principal market is an exchange) in which such securities are normally
  traded. Investments in foreign securities in the International Discovery
  Fund, the Balanced Allocation Fund, the Aggressive Allocation Fund and the
  Emerging Markets Fund are valued based on quotations from the primary
  market in which they are traded. The differences between the cost and
  market values of investments held by the variable net asset value funds are
  reflected as either unrealized appreciation or depreciation.

The Parkstone Group of Funds                                   December 31, 1997
                                                                     (Unaudited)

 
  SECURITY TRANSACTIONS AND RELATED INCOME:
 
  Security transactions are accounted for on the date the security is
  purchased or sold (trade date). Interest income is recognized on the
  accrual basis and includes, where applicable, the pro rata amortization of
  premium or discount. Dividend income is recorded on the ex-dividend date.
  Gains or losses realized from sales of securities are determined by
  comparing the identified cost of the security lot sold with the net sales
  proceeds.
 
  FOREIGN CURRENCY TRANSLATION:
 
  The market value of investment securities, other assets and liabilities of
  the International Discovery Fund, Balanced Allocation Fund, Aggressive
  Allocation Fund and Emerging Markets 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 International Discovery Fund, Balanced Allocation Fund, Aggressive
  Allocation Fund and Emerging Markets Fund isolate that portion of the
  results of operations resulting from changes in foreign exchange rates from
  the fluctuation arising from changes in market prices of securities held.
 
  Reported net realized foreign exchange gains or losses arise from sales and
  maturities of portfolio 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.
 
  REPURCHASE AGREEMENTS:
 
  The Funds may acquire repurchase agreements from member banks of the
  Federal Deposit Insurance Corporation with capital, surplus and undivided
  profits in excess of $100,000,000 (as of the date of their most recently
  published financial statements) and from registered broker/dealers which
  FIC deems creditworthy under guidelines approved by the Board of Trustees,
  subject to the seller's agreement to repurchase such securities at a
  mutually agreed-upon date and price. The repurchase price generally equals
  the price paid by a Fund plus interest negotiated on the basis of current
  short-term rates, which may be more or less than the rate on the underlying
  portfolio securities. The seller, under a repurchase agreement, is required
  to maintain the value of collateral held pursuant to the agreement at not
  less than the repurchase price (including accrued interest). Securities
  subject to repurchase agreements are held by the Funds' custodian or
  another qualified custodian or in the Federal Reserve/Treasury book-entry
  system. Repurchase agreements are considered to be loans by a Fund under
  the 1940 Act.
 
  REVERSE REPURCHASE AGREEMENTS:
 
  The Funds may also enter into reverse repurchase agreements, pursuant to
  which the Funds would sell portfolio securities to financial institutions
  such as banks and broker-dealers, and agree to repurchase them at a
  mutually agreed-upon date and price. At the time a Fund enters into a
  reverse repurchase agreement, it will place in a segregated custodial
  account assets having a value equal to the repurchase price (including
  accrued interest), and will subsequently continually monitor the account to
  ensure that such equivalent value is maintained at all times. Reverse
  repurchase agreements are considered to be borrowings by a Fund under the
  1940 Act.

The Parkstone Group of Funds                                   December 31, 1997
                                                                     (Unaudited)

 
  FORWARD CURRENCY CONTRACTS:
 
  The Funds 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 a 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. A 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.
 
  LENDING PORTFOLIO SECURITIES:
 
  In order to generate additional income, the Funds, except the Treasury
  Fund, (subject to limitations) may lend their portfolio securities to
  broker-dealers, banks, or institutional borrowers of securities which have
  been determined creditworthy under guidelines established by the Group's
  Board of Trustees in exchange for 100% collateral consisting of cash or
  securities.
 
  During the time portfolio securities are on loan, the borrower pays the
  Fund any dividends or interest received on such securities. Loans are
  subject to termination by the Fund or the borrower at any time. While a
  Fund does not have the right to vote securities on loan, each Fund intends
  to terminate the loan and regain the right to vote if that is considered
  important with respect to the investment. In the event the borrower
  defaults in its obligation to a Fund, such Fund bears the risk of delay in
  the recovery of its portfolio securities and the risk of loss of rights in
  the collateral.
 
  At December 31, 1997, the following funds had loaned securities with the
  following market value (amounts in thousands):

  The loaned securities were fully collateralized with cash or securities on
  deposit with the Group's custodian.
 
  OPTIONS TRANSACTIONS:
 
  In order to hedge investment positions and facilitate buying and selling
  securities, the variable net asset value funds may purchase call and put
  options and may write covered call options on individual securities and
  futures contracts. By writing call options, the variable net asset value
  funds receive a premium and become obligated during the term of the option
  to sell securities at a set price if the option is exercised. The variable
  net asset value funds will write only covered options, thereby owning the
  underlying securities in the case of call options. To cover put options,

The Parkstone Group of Funds                                   December 31, 1997
                                                                     (Unaudited)


  the variable net asset value funds will segregate cash or securities with a
  value at least equal to the exercise price. The risk in writing options is
  that the market value of the underlying securities could move in the
  opposite direction from what is anticipated. The variable net asset value
  funds also have the additional risk of not being able to enter into a
  closing transaction if a liquid secondary market does not exist. The Small
  Capitalization Fund, the Mid Capitalization Fund, the Large Capitalization
  Fund, and the Equity Income Fund may also use index options. Options on
  indices are similar to options on a securities except that, rather than the
  right to take or make delivery of securities at a specified price, options
  on indices gives the holder the right to receive, upon exercise of the
  options, an amount of cash if the closing level of the indices upon which
  the options are based are greater than, in the case of a call, or less
  than, in the case of a put, the exercise price of the options. In contrast
  to exchange-traded options, the variable net asset value funds may also
  write over-the-counter options where the completion of the obligation is
  dependent upon the credit standing of the other party. Upon writing a
  covered option, an amount equal to the premium is recorded by the variable
  net asset value funds as an asset or liability.
 
  The asset or liability is marked-to-market each day to reflect the current
  value of the option, resulting in unrealized appreciation or depreciation.
  The variable net asset value funds will realize a gain or loss upon
  expiration or closing of the option transaction. When an option is
  exercised, the premium amount is added to the proceeds from selling call
  options or subtracted from the cost of purchasing put options.
 
  DIVIDENDS TO SHAREHOLDERS:
 
  Dividends from net investment income are declared daily and paid monthly
  for the money market funds. Dividends from net investment income, if any,
  are declared and paid monthly for the variable net asset value funds.
  Distributable net realized capital gains, if any, are declared and
  distributed annually.
 
  Dividends from net investment income and from net realized capital gains
  are determined in accordance with income tax regulations which may differ
  from generally accepted accounting principles. These differences are
  primarily due to differing treatments for mortgage-backed securities,
  foreign currency transactions, expiring capital loss carryforwards and
  deferrals of certain losses. Accordingly, timing differences relating to
  shareholder distributions are reflected in the components of net assets and
  permanent book and tax differences relating to shareholder distributions
  have been reclassified to additional paid-in capital.
 
  FEDERAL INCOME TAXES:
 
  It is the policy of each of the Funds to qualify or continue to qualify as
  a regulated investment company by complying with the provisions available
  to certain investment companies, as defined in applicable sections of the
  Internal Revenue Code, and to make distributions of net investment income
  and net realized capital gains sufficient to relieve it from all, or
  substantially all, federal income taxes.
 
  OTHER:
 
  Expenses that are directly related to one of the Funds are charged directly
  to that Fund. Other operating expenses of the Group are prorated to the
  Funds on the basis of relative net assets.
 
  RECLASSIFICATIONS:
 
  Certain reclassifications have been made to the prior year financial
  statements and financial highlights in order to conform to the current
  period presentation.
