The Parkstone Advantage Fund                                      June 30, 1997



Dear Shareholders:
 
We're pleased to report that the six months ended June 30, 1997, was a period
of strong growth for the financial markets, and for the Parkstone Advantage
Fund. Over the course of the six-month period ended June 30, 1997, the Dow
Jones Industrial Average gained over 1225 points. While bonds attracted less
attention and generated less excitement than stocks, they, too, posted posi-
tive returns for the period.
 
Much of this activity was fueled by investors who continued to invest in mu-
tual funds at record levels. During the first half of 1997 alone, net assets
under management in the Parkstone Advantage Funds grew by $10.4 million from
78.9 million to $89.3 million, an increase of 13.2%. Moreover, at the end of
March, assets under management by First of America Investment Corporation to-
taled some $14.3 billion dollars.
 
TURNING TO THE MARKETS . . .
 
After climbing relentlessly higher for two years, stocks took a dive in March
and April. Consensus opinion was that a substantial correction had begun. With
economic growth numbers so strong, the Federal Reserve had just raised inter-
est rates. Moreover, the expectation was that, somewhat like 1994, they would
continue to do so until the economy softened, and perhaps, to investors' way
of thinking, a recession ensued. But those glum feelings didn't last. Like a
phoenix rising from the ashes, the stock market went on to hit new all-time
record highs day after day throughout the second quarter of 1997.
 
In short, the market took a licking and kept right on ticking. Why? First and
foremost, after the 1/4% increase in March, the Federal Reserve reassessed its
position and has not moved since. This is most unusual for Alan Greenspan and
crew. But they have good reasons. Economic growth cooled from 5.9% in the
first quarter to a more moderate 2%-3% in the second. News on the inflation
front is also very good--the core Consumer Price Index rate of inflation for
the 12 months ending in May is now just 2.5%.
 
ABOUT AS GOOD AS IT GETS
 
Low inflation, declining interest rates, increasing corporate profits--why
shouldn't the stock market celebrate? Indeed, as things currently stand, cor-
porate profits have been substantially underestimated by the market. Not only
have companies failed to disappoint, they have, week after week, surprised
virtually everyone in the marketplace.
 
The bond market, too, has taken notice of strong corporate profits and the es-
sentially benign inflation environment. One year ago, 30-year Treasury bonds
were yielding 7.2%. Last week they yielded 6.63%. With the Federal deficit es-
timated to have continued to shrink to a level of under $100 billion--in fact,
perhaps as low as $50 billion in the current fiscal year--there may be room
for long-term and short-term interest rates to decline further. (Historically,
business cycles do not stop of their own accord, but tend to be subdued by
higher interest rates induced by the Federal Reserve and/or by some unforeseen
external event such as war or other cataclysmic event.) As a result, after
several years of fluctuating in response to every rumor, statistic and eco-
nomic bulletin, the bond markets experienced a relatively tranquil first half
of the year.
 
CAN IT GET BETTER?
 
All right, profits look good, inflation looks good, and stock market prices
have never been better. In fact, they are somewhat overvalued, aren't they?
Yes, from a fundamental perspective, things are a little scary. Dividend
yields are too low. Price/earnings ratios are hitting historic highs--and you
would think that, at some point, they will have to return to more realistic
ranges. Ah, that's the key--you would think.
 
There are times in stock market cycles when the dominant force is market psy-
chology, and, at the moment, psychology looks great. But, beware; it can shift
quickly, or it can buoy a market for years. During the entire decade of the
Sixties, the S&P 500 traded at a price/earnings ratio of between 15 and 20
times earnings. The entire decade--not six days, six months or six years, but
the entire decade!
 
HOW HIGH IS TOO HIGH?
 
The common denominator between then and now is a low inflation rate. During
the early Sixties, as measured by the Consumer Price Index, inflation was
4.5%. By

the mid to late Sixties, it was 3% or less. The conclusion is, although the
stock market may be near the higher end of historic valuations, it is not un-
precedented. With the current level of inflation and interest rates, this valu-
ation could continue for some time. Of course, there could be a nasty 10% to
15% market correction at any time, but there won't be a calamity unless senti-
ment shifts dramatically.
 
So how high could the market go? Some pundits think we've seen the high. Others
project the Dow at 10,000 by the middle of 1998, and 18,000 by 2005. The truth
of the matter is, no one really knows. But one thing we all do know is that
market sentiment can shift on a dime--for reasons big or very, very small.

The Parkstone Advantage Fund                                       June 30, 1997


MID CAPITALIZATION FUND
 
While the Dow average gained almost 1000 points during the six months ended
June 30, 1997, the advance was a relatively narrow one. As they have for some
time, investors continued to favor larger capitalization stocks--and often-
times, only the very biggest and best known of those. Moreover, investor senti-
ment also shifted away from growth stocks to value. As a result, many sound
mid-cap and small-cap growth stocks were overlooked--and left behind.
 
Even in this environment, however, the quality of several of the Fund holdings
won over investors. In the first half of '97 alone, Baan (2.0% of the portfo-
lio's assets), a company involved in enterprise resource planning systems,
soared 98%. McAfee rose 43%, and Tellabs climbed 48% over the same period.
Overall, however, the six months ended June 30, 1997, were frustrating ones as
mid-cap and small- cap companies labored in the shadow of the large- caps. For
the period, the Fund posted a return of 2.95% versus a return of 12.99% for the
S&P Mid-Cap 400, the industry benchmark.
 
OPPORTUNITIES ABOUND
 
Overlooked by investors as they stampeded to large-cap stocks over the past
year, small- and mid-cap stocks are now offering investors very real value. In
fact, in comparison to the blue chips, they can even be considered cheap. Obvi-
ously, there is the possibility that the larger stocks will experience a cor-
rection in the coming months--which would bring these stocks more in line with
the rest of the market.
 
But there is an equally strong possibility that we will see small- and mid-cap
stocks start to catch up with larger stocks. Given the valuations of the blue
chips, we believe it's only a matter of time before investors move to capital-
ize on many of the truly astounding bargains now available in other sectors of
the marketplace.
 
As of June 30, 1997, the top five holdings in the Fund's portfolio were
HEALTHSOUTH (3.6% of the Fund's assets), Service Corp. (3.2%), Hospitality
Franchise Systems, Inc. (3.1%), McAfee Associates (2.8%) and Sunamerica
(2.8%).*

SMALL CAPITALIZATION FUND/+/
 
Very simply, the six months ended June 30, 1997, were frustrating ones for
small-cap growth investors. The market roared to record highs--but gains were
concentrated in a handful of the largest companies. And while all other sectors
of the market were left behind in the stampede, the small-cap sector was tram-
pled. Moreover, despite their fundamental strength and solid prospects, small-
cap growth stocks fared the worst, as what attention investors paid to the sec-
tor focused on value-oriented companies.
 
Invested primarily in growth-oriented small-cap stocks, the Fund's performance
was impacted by this shift in market sentiment. For the six months ended June
30, 1997, the Fund posted a total return of -4.07% versus a return of 10.20%
for the Russell 2000, which is heavily weighted in value-oriented small-cap
stocks.
 
LOOKING TOWARD THE FUTURE
 
Regardless of market sentiment, the prospects for the small-cap growth sector
are very bright indeed. Out of the market's spotlight for almost two years,
these companies have continued to plug away--many growing at a rate as high as
35% a year. Their balance sheets are strong. Their long-term prospects are sol-
id. Yet, many have seen their stock prices fall, or even plummet.
 
Consequently, valuations in the small-cap growth sector, in comparison to the
large-caps, are now very, very cheap. Attractive opportunities abound in indus-
tries across the market, from health care and technology to financial services
and entertainment companies. In the months ahead, as the economy slows and in-
vestors' infatuation with large-cap issues fades, we expect investors will re-
alize this and return to the sector, seeking growth.
 
As of June 30, 1997, the top five holdings in the Fund's portfolio were Sanmina
(3.3% of the Fund's assets), Dura Pharmaceuticals (3.3%), Omnicare (3.1%), Con-
cord EFS (2.8%) and Regal Cinemas (2.4%).*

    on average.

INTERNATIONAL DISCOVERY FUND/+/
 
Few markets worldwide could compete with the U.S stock market as it continued
the longest and strongest bull run in its history. Nonetheless, the six months
ended June 30, 1997, were very profitable ones for international investors.
Moreover, to the surprise of nearly everyone, the Japanese market proved to be
the best performing major market in U.S. dollars in the second quarter of
1997. With approximately 24% of its assets invested in Japan, the Fund bene-
fited handsomely from the rebound.
 
Investments in Continental Europe also made solid contributions to performance
as economic activity--helped by the low-interest-rate, low-inflation environ-
ment--continued to pick up. While smaller markets throughout the Pacific Basin
region produced mixed results, activity in any one market was not dramatic
enough to impact performance one way or another. Consequently, for the six
months ended June 30, 1997, the Fund posted a return of 10.92% versus its
benchmark, the EAFE (Morgan Stanley Capital International Europe, Australia
and Far East) Index, which posted a return of 11.21% for the same period.
 
PROSPECTS WORLDWIDE ARE BRIGHT
 
Overshadowed by the fantastic performance of the U.S. stock market, markets
worldwide have made solid progress over the past year. In Europe, the driving
force behind stocks has been the prospect of economic union. To be eligible to
join the union, countries have had to implement fiscal and monetary policies
that have led to a low-interest-rate, low-inflationary environment. Whether
the union will materialize or not is still problematic--nonetheless, the fi-
nancial markets on the Continent are beginning to experience some of the bene-
fits of a united Europe.
 
Also in the news during the period was the British handover of Hong Kong to
China. Clearly, this has created a good deal of uncertainty in the Pacific Ba-
sin markets. But, the success of Hong Kong has not been lost on the Chinese
people, or on the Chinese government. We strongly believe that Hong Kong will
have a much greater influence on China than China does on Hong Kong. Early in
the next century, we expect China to become one of the economic powerhouses of
the world--and to offer investors truly enormous growth potential.
 
As of June 30, 1997, the Fund was widely diversified, with 89 holdings in 25
different markets. Approximately 42% of the portfolio's assets were invested
in Continental Europe, 24% in Japan, 9% in the United Kingdom, 8% in Latin
America, 4% in Canada and 11% in other smaller markets around the world.
 
As of the same date, the Fund's top five holdings were Rohm (2.5% of the port-
folio's assets), Takeda Chemical (2.5%), Telebras-Spons (2.2%), TDK Corp.
(2.2%) and Oce-Van Der Grinten (2.0%).*

The Parkstone Advantage Fund                                      June 30, 1997

 
BOND FUND
 
The six months ended June 30, 1997, were relatively quiet in the fixed-income
markets. Growth over the course of the period was stronger than anticipated,
but inflation pressures remained benign. Moreover, the Federal Reserve's move
to increase rates modestly in early spring quickly stamped out any sparks that
might have been threatening to ignite. Rates spurted higher briefly, then
gradually fell back as the economy showed signs of softening as the period
drew to a close.
 
Rather than attempting to chase rates and call each turn, we focused on yield
enhancement instead of on price appreciation. Also, the average maturity of
the portfolio was maintained at a level slightly under the industry average.
Given the strength of corporate balance sheets, corporate bonds were strong
performers throughout the period, and the Fund benefited from its heavy
weighting in the sector. Mortgage-backed securities also made a solid contri-
bution to performance. As a result, for the six months ended June 30, 1997,
the Fund performed in line with its benchmark, the Salomon Brothers Broad In-
dex, and produced a total return of 2.32%.
 
SUNNY SKIES, FEW CLOUDS
 
Barring a major disruption in the economy, we expect the environment in the
fixed-income markets to continue to be relatively calm over the next several
months. While the rate of corporate profit growth may decline, in balance
sheets are in the best shape they've been for years. News from markets outside
the United States is good, too. Finally, the market is now beginning to recog-
nize and adjust for the possibility that Federal borrowing needs may decline,
the budget deficit does actually shrink in the months ahead, opening the door
for lower rates. And, with the surprise element taken out of the equation, the
result is likely to be simply a firmer market for government bonds in the fu-
ture.
 
As of June 30, 1997, approximately 37% of the Fund's assets were invested in
corporate bonds, 14% in mortgage-backed and asset-backed securities, 23% in
U.S. Treasuries, with the remainder invested in agency-backed securities and
cash & cash equivalents. As of the same date, the average credit quality of
the portfolio was Aaa; the average maturity, 9.5 years.*

The Fund's performance is 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 Advantage Bond Fund reflects the deduction of fees for these value-
added services. Past performance is not predictive of future results. The total
return of the Fund does not reflect the effect of any insurance charges or the
annual maintenance fee. Such charges and expenses would reduce the performance
quoted. The investment return and NAV will fluctuate, so that an investor's
shares, when redeemed, may be worth more or less than the original cost.

Portfolio Performance Discussion, continued
- --------------------------------------------------------------------------------
The Parkstone Advantage Fund                                       June 30, 1997


PRIME OBLIGATIONS FUND/+/
 
Stronger than expected economic growth caused investors to keep a wary watch on
inflation numbers during the six months ended June 30, 1997. But, contrary to
historical precedent, increased economic activity did not increase inflationary
pressures. Nevertheless, the Federal Reserve hiked interest rates 1/4% in the
first quarter. Whatever inflation anxiety lingered in the marketplace was ef-
fectively doused. As a result, while some sectors of the market were more ac-
tive than others, the overall environment was relatively stable.
 
Clearly, much of investors' apprehensiveness regarding inflation has dissipated
in recent months as growth has weakened slightly. In fact, there is growing
sentiment in the marketplace for a lowering of rates. But, Federal Reserve ac-
tion has always trailed rather than led the markets, so a dramatic change in
this direction seems somewhat unlikely in the very near term. Nonetheless, with
the economy softening and inflation anxieties disappearing, minus a major
change in the environment, rates may drift lower of their own accord in the
months ahead.
 
Yet, given the economy's strength over the past two years, we expect to ap-
proach the marketplace cautiously in the weeks prior to the Federal Reserve's
August meeting. Maturities have been lengthened slightly. At the same time, we
have maintained the flexibility to respond quickly to any surprise the economy
might offer, or to increase rates by the Federal Reserve.
 
As of June 30, 1997, approximately 52.4% of the Fund's assets were invested in
commercial paper, with the remainder invested in overnight securities. The av-
erage maturity of the Fund's holdings was 60 days.*

*   The portfolio's composition is subject to change.
/+/ An investment in the Funds is neither insured nor guaranteed by the U.S.
    Government. Yields will fluctuate, and there can be no assurance that the
    Funds will be able to maintain a stable net asset value of $1.00 per share.

The Parkstone Advantage Fund                                       June 30, 1997
                                                                     (Unaudited)
 
1. ORGANIZATION:
 
 The Parkstone Advantage Fund (the "Company") is registered under the
 Investment Company Act of 1940, as amended, as a diversified, open-end
 investment company.
 
 The Company is authorized to issue an unlimited number of shares which are
 shares of beneficial interest without par value. The Company presently offers
 series of shares of the Prime Obligations Fund, Bond Fund, Mid Capitalization
 Fund (formerly known as the Equity Fund), Small Capitalization Fund and
 International Discovery Fund (collectively, "the Funds" and individually, a
 "Fund"). Sales of shares of the Fund may only be made to separate accounts of
 various life insurance companies ("Participating Insurance Companies"). As of
 June 30, 1997, the only Participating Insurance Company is Security Benefit
 Life Insurance Company. First of America Investment Corp. ("FIC"), a wholly-
 owned subsidiary of First of America Bank, serves as investment adviser to
 the Company.
 
 On April 30, 1997, the Board resolved that the name of the Trust's Equity
 Fund portfolio be, and thereby was, changed to the Mid Capitalization Fund.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
 The following is a summary of significant accounting policies followed by the
 Company 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 Prime Obligations Fund 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 amortized on a constant basis to the
  maturity of the security. In addition, the Prime Obligations Fund may not
  (a) purchase any investment 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 and foreign government bonds and U.S. Government securities of the
  Bond Fund, Mid Capitalization Fund, Small Capitalization Fund and
  International Discovery Fund (collectively, "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. Amortization of premium or
  discount is recognized on the sale or maturity of the security for the Bond
  Fund. Investments in foreign securities in the International Discovery Fund
  are valued based on quotations from the primary market in which they are
  traded. Investments in investment companies are valued at their net asset
  values as reported by such investment companies. 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 Advantage Fund                                       June 30, 1997
                                                                     (Unaudited)

  SECURITIES TRANSACTIONS AND RELATED INCOME:
 
  Securities transactions are accounted for on the date the security is
  purchased or sold (trade date). Interest income is recognized on the
  accrual basis. 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 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 date of each transaction.
 
  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. dollars 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 exchanges
  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 the underlying securities
  at a mutually agreed-upon date and price. The repurchase price generally
  equals the price paid by the Fund plus interest negotiated on the basis of
  current short-term rates, which may be more or less than the rate on the
  underlying collateral. 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.
 
  DIVIDENDS TO SHAREHOLDERS:
 
  For the Prime Obligations Fund, dividends of net investment income are
  declared daily and paid monthly and distributable net realized capital
  gains are declared and distributed at least annually.
 
  Dividends from net investment income and distributable realized capital
  gains are declared and paid at least annually for the variable net asset
  value funds. The character of distributions made during the year from net
  investment income or net realized gains may differ from their ultimate
  characterization for federal income tax purposes. These differences are
  primarily due to the recharacterization of foreign currency gains and
  losses.

The Parkstone Advantage Fund                                       June 30, 1997
                                                                     (Unaudited)

 
  FEDERAL INCOME TAXES:
 
  It is the policy of each of the Funds to 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 for the Company are prorated to the
  Funds on the basis of relative net assets.
 
3. INVESTMENT RISKS:
 
 The International Discovery Fund's investment in foreign securities may
 involve risks not present in domestic investments. Since foreign securities
 are denominated in foreign currencies and pay interest or dividends in
 foreign currencies, changes in the relationship of these currencies to the
 U.S. dollar can significantly affect the value of the investment and
 operations of the Fund. Foreign investments may also subject the Fund to
 foreign government exchange restrictions, expropriation, taxation or other
 political, social or economic developments, all of which could affect the
 market and/or credit risk of the investments.
 
4. PURCHASES AND SALES OF SECURITIES:
 
 Purchases and sales of securities (excluding short-term securities) for the
