Dear Shareholder:
 
We are pleased to present this Semi-Annual Report for the following Vista Fixed
Income Funds for the six months ended April 30, 1997:
 
    - U.S. Treasury Income Fund
    - U.S. Government Securities Fund
    - Bond Fund
    - Short-Term Bond Fund
 
Inside, you'll find information on the performance of each fund over the past
six months along with a market overview and portfolio commentary.
 
ECONOMIC GROWTH REPORTS CONTINUE TO DRIVE FIXED INCOME MARKETS
 
Over the six month period, the yield on the 30-year U.S. Treasury bond rose from
6.65% to 6.95%. However, this slight change masks a high degree of volatility in
fixed income markets resulting from changing perceptions of the strength of the
U.S. economy.
 
As the period began, long-term interest rates were falling as the market rallied
sharply on reports of a slowing economy. The turning point in yields came in
early December 1996 in response to weaker demand and fears that the Federal
Reserve Board might raise interest rates to quell financial market speculation.
For the next several months, the market was inconsistent as investors reacted to
each new report on the economy's strength and attempted to determine the Fed's
stance. By the end of February, with the economy showing unexpectedly strong
growth, it was widely expected that the Fed would raise the Federal Funds rate
at its March meeting to cool the economy and preempt inflation, which it did. As
the reporting period ended, rates were again trending downward but remained
volatile given uncertainty over the sustainability of economic growth and future
Fed actions.
 
MANAGING YOUR MONEY IN A VOLATILE ENVIRONMENT
 
Vista's fixed income management team relied on a variety of tools to manage your
investment during the reporting period. Although interest rate trends are always
an important consideration, the main ways your management team adds value are
through analyzing the relative value of different types of fixed income
securities and carefully assessing the credit, structure and liquidity risks of
individual securities. In this way, Vista seeks to provide you with investments
that can meet your needs in any interest rate environment.
 
We appreciate the confidence you have placed in us and look forward to serving
your investment needs for many years to come. If you have any questions, please
call your investment professional or 1-800-34-VISTA.
 
Sincerely,
/s/ Fergus Reid
Fergus Reid
Chairman

VISTA U.S. TREASURY INCOME FUND
 
Vista U.S. Treasury Income Fund, which seeks to provide income through a
portfolio of high-quality U.S. Treasury Bonds, had a total return of 0.83% for
the six months ended April 30, 1997 (Class A Shares, without sales charges).
 
FUND TAKES ADVANTAGE OF NOVEMBER RALLY
 
The management team began the period expecting that moderating economic growth
would lead to lower interest rates, and thus positioned the Fund to have a
slightly-longer duration than the duration of its benchmark, the Lehman Treasury
Bond Index. This stance proved beneficial as the market rallied in November.
Although the management team ended 1996 by forecasting that the economy would
accelerate in early 1997, it nonetheless maintained the slightly-long duration
in anticipation of moderating economic growth and continued benign inflation
later
in 1997.
 
The slightly-long duration continued through February when rates began rising.
At this point the management team reduced duration to neutral and adopted a
barbell strategy to take advantage of points of value along the yield curve. The
barbell strategy, which involved investments at the short and long ends of the
yield curve while avoiding bonds with medium-term maturities, helped the Fund
perform well in March's rising interest rate environment.
 
ECONOMIC GROWTH, FED ACTIONS WILL DETERMINE BOND MARKET COURSE
 
As the reporting period ended, the Fund was maintaining a cautiously-neutral
benchmark duration. This defensive stance was designed to protect shareholders
from the effects of any further action by the Federal Reserve Board on
short-term interest rates. Given its expectation that economic growth will cool
down as 1997 progresses, the management team intends to extend to a
slightly-longer duration than the duration of its benchmark and take advantage
of continued market volatility caused by managing duration within an expected
narrow trading range.

Past performance is not predictive of future performance. Investment return and
principal value will fluctuate with market conditions. When shares are redeemed,
they may be worth more or less than their original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class A
shares of Vista U.S. Treasury Income Fund, the Lipper General U.S. Government
Funds Average and the Lehman Treasury Bond Index from September 30, 1987 to
April 30, 1997. The Fund's performance includes a 4.50% sales charge and assumes
the reinvestment of all dividends and capital gains. Also, certain fees were
waived during the period. Had they not been waived, total returns would have
been lower. The Fund commenced operations on 9/8/87. Class B Shares were
introduced on 11/4/93. Investors should note that information presented for
Class B prior to their introduction is based upon historical expenses of the
predecessor Class A Shares, which are lower than the actual expenses of the
Class B Shares. Additionally, annualized figures have been restated to reflect
the maximum 5% contingent deferred sales charge that applies to the Fund's B
Shares.
 
The Lipper General U.S. Government Funds Average represents the average
performance of a universe of 167 actively managed U.S. government income funds.
Lipper is an independent mutual fund performance monitor whose results are based
on total return and do not reflect a sales charge.
 
The Lehman Treasury Bond Index is a replica (or model) of the U.S. government
treasury securities market. The index is unmanaged and reflects the reinvestment
of dividends. An individual cannot invest in the index.

VISTA U.S. GOVERNMENT SECURITIES FUND
 
Vista U.S. Government Securities Fund, which seeks income and capital
appreciation by investing in a portfolio of high-quality, long-term U.S.
government and agency bonds, provided shareholders with a total return of 1.21%
for the six months ended April 30, 1997 (Class A Shares, without sales charges).
 
MANAGEMENT TEAM PURSUES ACTIVE MANAGEMENT IN A VOLATILE ENVIRONMENT
 
In seeking to provide you with favorable returns on your investment in any
interest rate environment, the management team's most important tool is its
relative value analysis. This analysis seeks to determine which
securities -- either U.S. Treasuries or mortgage-backed issues -- are likely to
outperform in a given environment. Further, the relative value analysis guides
the management team in selecting the duration of individual securities based on
different points of value along the yield curve.
 
This relative value analysis led the management team to begin the period with an
overweight allocation to mortgage-backed securities. These securities' higher
yields, combined with a neutral portfolio duration, left the Fund well
positioned for November's moderate rally.
 
FUND SHIFTS TO MORTGAGES IN LATE 1996
 
At the end of 1996, the relative value analysis pointed the management team in
the direction of mortgage-backed securities. This helped the Fund perform well
as markets fluctuated in early 1997 and, subsequently, as rates began a moderate
uptrend in February. At that point, the management team reduced duration to
neutral and adopted a barbell strategy that sought to take advantage of stronger
relative values at the short and long ends of the yield curve.
 
As the reporting period ended, the Fund took profits on some of its mortgage
securities but maintained slightly-overweight allocation to the sector. By early
May, the management team was considering a more aggressive move back to
mortgages given that the market had begun to exhibit signs of settling yet again
into a trading range. In such an environment, the extra yield provided by
mortgage-backed securities tends to help overall performance.

Past performance is not predictive of future performance. Investment return and
principal value will fluctuate with market conditions. When shares are redeemed,
they may be worth more or less than their original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class I
shares of Vista U.S. Government Securities Fund, the Lipper General U.S.
Government Funds Average and the Merrill Lynch Government Index and a composite
of the Merrill Lynch Government and Corporate Indexes from February 28, 1993 to
April 30, 1997. The Fund's performance does not include a sales charge and
assumes the reinvestment of all dividends and capital gains. The Fund commenced
operations on 2/19/93. Class A Shares were introduced on 5/6/96. Investors
should note that information presented for Class A Shares prior to their
introduction is based upon historical expenses of the predecessor Class I
Shares, which are lower than the actual expenses of the Class A Shares.
Additionally, annualized figures have been restated to reflect the initial 4.50%
sales charge that applies to the Fund's A Shares. Class I shares have a
$1,000,000 minimum initial deposit and carry no sales charge. Also, certain fees
were waived during the period. Had they not been waived, total returns would
have been lower.
 
The Lipper General U.S. Government Funds Average represents the performance of a
universe of 167 actively managed U.S. government income mutual funds. Lipper is
an independent mutual fund performance monitor whose results are based on total
return and do not reflect a sales charge.
 
The Merrill Lynch (ML) Government Index consists of bonds with a maturity
greater than or equal to one year. The ML Mortgage Master Index consists of
fixed-rate corporate interest-bearing bonds. The indexes are unmanaged and
reflect reinvestment of dividends. An individual cannot invest in an index.

VISTA BOND FUND
 
Vista Bond Fund, which seeks to provide a high level of current income through a
portfolio of investment-grade government, asset-backed and corporate bonds, had
a total return of 1.30% for the six months ended April 30, 1997 (Class A shares,
without sales charges).
 
RELATIVE VALUE ANALYSIS KEY TO MANAGEMENT DECISIONS
 
In seeking to provide you with favorable returns on your investment in any
interest rate environment, the management team's most important tool is its
relative value analysis. This analysis seeks to determine which market
sector -- U.S. Treasuries, mortgage-backed or corporate securities -- is likely
to outperform in a given environment. The relative value analysis also guides
the management team in selecting the duration of the portfolio based on
different points of value along the yield curve. Additionally, the management
team carefully analyzes each potential investment for credit, structure and
liquidity risks, and uses this analysis to determine whether each security is
over- or under-valued in the market.
 
This relative value analysis led the management team to begin the period with an
overweight allocation to mortgage-backed securities. These securities' higher
yields, combined with a neutral portfolio duration, left the Fund well
positioned for November's moderate rally.
 
FUND SHIFTS EMPHASIS TO MORTGAGES AND SELECTED CORPORATE SECURITIES IN LATE 1996
 
At the end of 1996, the relative value analysis pointed the management team in
the direction of mortgage-backed securities as well as selected corporate
securities. This helped the Fund perform well as mortgages and corporates were
the top-performing sectors in early 1997 and, subsequently, as rates began a
moderate uptrend in February. At that point, the management team reduced
duration to neutral and adopted a barbell strategy that sought to take advantage
of stronger relative values at the short and long ends of the yield curve.
 
As the reporting period ended, the Fund took profits on some of its
mortgage-backed securities but maintained a relatively-neutral sector
allocation. By early May, the management team was considering a more aggressive
move back into mortgage-backed and corporate securities given that the market
had begun to exhibit signs of settling yet again into a trading range. In such
an environment, the extra yield provided by these sectors tends to help overall
performance.

Past performance is not predictive of future performance. Investment return and
principal value will fluctuate with market conditions. When shares are redeemed,
they may be worth more or less than their original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class I
shares of Vista Bond Fund, the Lipper Corporate Debt BBB-Rated Funds Average and
the Lehman Aggregate Bond Index from November 30, 1990 to April 30, 1997. The
Fund's performance assumes reinvestment of all dividends and capital gains and
does not include a sales charge. Class I shares have a $1,000,000 minimum
initial deposit and carry no sales charge. The Fund commenced operations on
11/30/90. Class A and B Shares were introduced on 5/6/96. Investors should note
that information presented for Class A and Class B Shares prior to their
introduction is based upon historical expenses of the predecessor Class I
Shares, which are lower than the actual expenses of the Class A Shares and Class
B Shares. Additionally, annualized figures have been restated to reflect the
maximum initial 4.50% sales charge on Class A Shares and the maximum 5%
contingent deferred sales charge that applies to the Fund's B Shares. Also,
certain fees were waived during the period. Had they not been waived, total
returns would have been lower.
 
The Lipper Corporate Debt BBB-Rated Funds Average represents the average
performance of a universe of 91 actively managed BBB-rated corporate debt funds.
Lipper is an independent mutual fund performance monitor whose results are based
on total return and do not reflect a sales charge.
 
The Lehman Aggregate Bond Index is composed of the Lehman Government/Corporate
Index and the Mortgage-Backed Securities Index and includes U.S. Treasury
issues, agency issues, corporate bond issues and mortgage-backed securities. The
index is unmanaged and reflects the reinvestment of dividends. An individual
cannot invest in the index.

VISTA SHORT-TERM BOND FUND
 
Vista Short-Term Bond Fund, which seeks current income by investing in a
portfolio of short-term corporate and government securities, provided
shareholders with a total return of 2.13% for the six months ended April 30,
1997 (Class A shares, without sales charges).
 
MANAGEMENT TEAM TAKES ADVANTAGE OF FUND'S FLEXIBILITY
 
In seeking to provide you with relative price stability as well as high current
income on your investment, the management team has the flexibility to choose
from a wide range of short-term securities and to adjust the fund's duration to
take advantage of different points of value along the short-term yield curve. In
seeking to do so, the management team relies on its relative value analysis and
ability to analyze the credit, structural and liquidity characteristics of
individual fixed-income securities.
 
Using these tools, the management team began the period with an overweight
allocation to asset-backed securities, which tend to perform better during
market rallies. These securities' higher yields, combined with a neutral
portfolio duration, left the Fund well positioned for November's moderate rally.
 
FUND CUTS DURATION AS ECONOMIC GROWTH STRENGTHENS
 
At the end of 1996, the relative value analysis pointed the management team in
the direction of mortgage-backed securities as well as selected corporate
securities, whose higher yields are often beneficial in neutral-to-slightly
rising interest rate environments. This helped the Fund perform well during the
fluctuating markets in early 1997 and, subsequently, as rates began a moderate
uptrend in February. At that point, the management team also reduced duration to
neutral and moved more into the two-year maturities to take advantage of the
steepness at the short end of the yield curve.
 
As the reporting period ended, the Fund was maintaining a relatively-neutral
duration while continuing to emphasize mortgage-backed and corporate securities.
Given the management team's ability to analyze different types of risks, the
Fund will continue to use mortgage-backed, asset-backed and corporate securities
to enhance yield while maintaining a strong focus on relative stability of
principal.

Past performance is not predictive of future performance. Investment return and
principal value will fluctuate with market conditions. When shares are redeemed,
they may be worth more or less than their original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class I
shares of Vista Short-Term Bond Fund, the Lipper Short Investment Grade Debt
Funds Average and the Lehman Brothers 1-3 year Government Bond Index from
November 30, 1990 to April 30, 1997. The Fund's performance assumes reinvestment
of all dividends and capital gains and does not include a sales charge. The Fund
commenced operations on 11/30/90. Class A Shares were introduced on 5/6/96.
Investors should note that information presented for Class A Shares prior to
their introduction is based upon historical expenses of the predecessor Class I
Shares, which are lower than the actual expenses of the Class A Shares.
Additionally, annualized figures have been restated to reflect the maximum 1.50%
sales charge that applies to the Fund's A Shares. Class I Shares have a
$1,000,000 minimum initial deposit and carry no sales charges. Also, certain
fees were waived during the period. Had they not been waived, total returns
would have been lower.
 
The Lipper Short-Term Investment Grade Debt Funds Average represents the average
performance of a universe of 96 actively managed short investment grade debt
funds. Lipper is an independent mutual fund performance monitor whose results
are based on total return and do not reflect a sales charge.
 
The Lehman Brothers 1-3 Year Government Bond Index is composed of bonds covered
by the Government Bond Index with maturities of one to three years. The index is
unmanaged and reflects the reinvestment of dividends. An individual cannot
invest directly in the index.

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS April 30, 1997 (unaudited)
- --------------------------------------------------------------------------------
1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES -- Mutual Fund Group (the
"Trust") was organized on May 11, 1987 as a Massachusetts Business Trust, and is
registered under the Investment Company Act of 1940, as amended, (the "1940
Act") as an open-end management investment company. Vista U.S. Treasury Income
Fund ("VUSTI") (formerly the Vista U.S. Government Income Fund), Vista U.S.
Government Securities Fund ("VUSGS"), Vista Bond Fund ("VBF"), and Vista
Short-Term Bond Fund ("VSTBF"), collectively, the "Funds", are four separate
portfolios of The Trust.
 
The Funds offer various classes of shares as follows:
 
<TABLE>
<CAPTION>
 Fund                                    Classes Offered
- ------     ---------------------------------------------------------------------------
<S>        <C>
VUSTI      Class A, Class B
VUSGS      Class A, Institutional
VBF        Class A, Class B, Institutional
VSTBF      Class A, Institutional
</TABLE>
 
Class A shares generally provide for a front-end sales charge while Class B
shares provide for a contingent deferred sales charge. No sales charges are
assessed with respect to the Institutional Class. All classes of shares have
equal rights as to earnings, assets and voting privileges except that each class
may bear different distribution fees and each class has exclusive voting rights
with respect to its distribution plan.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.
 
    The following is a summary of significant accounting policies followed by
    the Funds:
 
    A.   Valuation of investments -- Bonds and other fixed income securities
    (other than short-term obligations), including listed issues, are valued on
    the basis of valuations supplied by pricing services or by matrix pricing
    systems of a major dealer in bonds. Short-term debt securities with 61 days
    or more to maturity at time of purchase are valued, through the 61st day
    prior to maturity, at market value based on quotations obtained from market
    makers or other appropriate sources; thereafter, the value on the 61st day
    is amortized on a straight-line basis over the remaining number of days to
    maturity. Short-term investments with 60 days or less to maturity at time of
    purchase are valued at amortized cost, which approximates market. Portfolio
    securities for which there are no such quotations or valuations are valued
    at fair value as determined in good faith by or at the direction of the
    Trustees.
 
    B.   Repurchase agreements -- It is the Trust's policy that repurchase
    agreements are fully collateralized by U.S. Treasury and Government Agency
    securities. All collateral is held by the Trust's custodian bank,
    subcustodian, or a bank with which the custodian bank has entered into a
    subcustodian agreement, or is segregated in the Federal Reserve Book Entry
    System. In connection with transactions in repurchase agreements, if the
    seller defaults and the value of the collateral declines, or if the seller
    enters an insolvency proceeding, realization of the collateral by the Trust
    may be delayed or limited.
 
    C.   Futures contracts -- When a Fund enters into a futures contract, it
    makes an initial margin deposit in a segregated account, either in cash or
    liquid securities. Thereafter, the futures contract is marked to market and
    the Fund makes (or receives) additional cash payments daily to the broker.
    Changes in the value of the contract are recorded as unrealized
    appreciation/depreciation until the contract is closed or settled.
 
    The Funds may enter into futures contracts only on exchanges or boards of
    trade. The exchange or board of trade acts as the counterparty to each
    futures transaction, therefore, the Fund's credit risk is limited to failure
    of the exchange or board of trade.
 
    As of April 30, 1997, the Funds had no outstanding futures contracts.
 
    D.   Written options -- When a Fund writes an option an amount equal to the
    premium received by the Fund is included in the Fund's Statement of Assets
    and Liabilities as an asset and corresponding liability. The amount of the
    liability is adjusted daily to reflect the
 
                                       21

    current market value of the written options and the change is recorded in a
    corresponding unrealized gain or loss account. When a written option expires
    on its stipulated expiration date, or when a closing transaction is entered
    into, the related liability is extinguished and the Fund realizes a gain (or
    loss if the cost of the closing transaction exceeds the premium received
    when the option was written).
 
    The VUSTI writes options on U.S. Treasury futures. These options are settled
    for cash and subject the Fund to market risk in excess of the amounts that
    are reflected in the Statement of Assets and Liabilities. The Fund, however,
    is not subject to credit risk on written options as the counterparty has
    already performed its obligation by paying a premium at the inception of the
    contract.
 
    As of April 30, 1997, VUSTI had no outstanding written options.
 
    E.   Security transactions and investment income -- Investment transactions
    are accounted for on the trade date (the date the order to buy or sell is
    executed). Securities gains and losses are calculated on the identified cost
    basis. Interest income is determined on the basis of coupon interest accrued
    adjusted for amortization of premiums, except VUSTI, and accretion of
    discounts.
 
    F.   Expenses -- Expenses directly attributable to a Fund are charged to
    that Fund; other expenses of the Trust are allocated proportionately among
    each of the Funds within the Trust in relation to the net assets of each
    Fund or on another reasonable basis. Expenses directly attributable to a
    particular class are charged directly to such class. In calculating net
    asset value per share of each class, investment income, realized and
    unrealized gains and losses and expenses other than class specific expenses
    are allocated daily to each class of shares based upon the proportion of net
    assets of each class at the beginning of each day.
 
    G.   Organization costs -- Organization and initial registration costs
    incurred in connection with establishing the Funds have been deferred and
    are being amortized on a straight-line basis over a sixty month period
    beginning at the commencement of operations of each Fund.
 
    H.   Federal income taxes -- Each Fund is treated as a separate taxable
    entity for Federal income tax purposes. The Trust's policy is to comply with
    the provisions of the Internal Revenue Code applicable to regulated
    investment companies and to distribute to shareholders all of its
    distributable net investment income, and net realized gain on investments.
    In addition, the Trust intends to make distributions as required to avoid
    excise taxes. Accordingly, no provision for Federal income or excise tax is
    necessary.
 
    I.   Distributions to shareholders -- Dividends and distributions paid to
    shareholders are recorded on the ex-dividend date. The amount of dividends
    and distributions from net investment income and net realized capital gains
    is determined in accordance with Federal income tax regulations, which may
    differ from generally accepted accounting principles. To the extent these
    "book/tax" differences are permanent in nature, (i.e., that they result from
    other than timing of recognition -- "temporary differences") such amounts
    are reclassified within the capital accounts based on their Federal
    tax-basis treatment. Dividends and distributions which exceed net investment
    income or net realized capital gains for financial reporting purposes but
    not for tax purposes are reported as distributions in excess of net
    investment income or net realized capital gains.
 
    J.   Dollar rolls -- The funds (with the exception of VUSTI) enter into
    dollar rolls in which the Funds sell mortgage-backed securities for delivery
    in the current month and simultaneously contract to repurchase substantially
    similar (same type, coupon and maturity) securities on a specified future
    date. During the roll period, the Funds forgo principal and interest paid on
    the securities. The Funds are compensated by the interest earned on the cash
    proceeds of the initial sale and a fee earned for entering into the roll
    transaction. The fee is amortized into income over the duration of the roll
    transaction.

7.   ACQUISITION -- On May 6, 1996, The Vista U.S. Government Securities Fund
acquired the net assets of the Hanover U.S. Government Fund in a tax-free
reorganization. At the time of the reorganization, the acquired Fund had
approximately $81 million in net assets. The Vista Fund had no assets and no
activity prior to the acquisition. The information included in the financial
statements for VUSGS for the period prior to May 6, 1996 relates to the
predecessor Hanover Fund.
 
Also on May 6, 1996, the Vista Short-Term Bond Fund acquired all the net assets
(approximately $9.5 million) of the Hanover Short Term U.S. Government Fund
pursuant to a plan of reorganization approved by Hanover Fund shareholders in
April of 1996. The acquisition was accomplished by a tax-free exchange of
shares, whereby the Hanover Shareholders surrendered 976,558 shares (net assets
of $9.5 million) of the Hanover Short Term U.S. Government Fund in exchange for
944,428 shares of the Vista Short-Term Bond Fund. The post-merger net assets of
the combined Fund were approximately $46,118,000.

Dear Shareholder:
 
We are pleased to present the semi-annual reports for the following Vista
International Funds for the six months ended April 30, 1997:
 
<TABLE>
    <S>                                    <C>
    - International Equity Fund            - Japan Fund
    - European Fund                        - Southeast Asian Fund
</TABLE>
 
EUROPEAN MARKETS FORGE AHEAD WHILE JAPANESE STOCKS FALTER
 
Global equity markets diverged on hemispheric lines during the six months ended
April 30, 1997, with markets in the United States, Europe and Latin America
posting robust gains while those in Japan and most of Southeast Asia turning in
negative performance.
 
As measured by the MSCI Europe Index, European equity markets had a dollar-based
total return of 11.96% for the six-month period as investors responded
positively to generally lower interest rates and improving corporate
performance. Despite low interest rates in Japan, however, the situation was far
different as the stock market continued to suffer from a lack of widespread
economic growth and concerns over new taxes. For the period, the Tokyo SE
(Topix) 1st Section declined (-7.05%) sharply.
 
LATIN AMERICAN EQUITY RETURNS AMONG WORLD'S BEST
 
Latin American equity markets were clearly world beaters during the reporting
period, with the MSCI Latin American Index gaining 25.42% as the Brazilian
market led the way. These high returns were not matched in the emerging markets
of Southeast Asia, however, as concerns about US interest rates held most
regional markets down.
 
While it is impossible to predict the performance of these international markets
over the short term, it's clear that more and more of the world's population is
embracing capitalist enterprise and the financial markets. This is creating
excellent long-term prospects for diversified investors who are able to tolerate
occasional periods of volatility.
 
We appreciate that you have chosen Vista to manage your international
investments and look forward to serving your investment needs for many years to
come.
 
Sincerely,
/s/ Fergus Reid
Fergus Reid
Chairman

VISTA EUROPEAN FUND
 
Vista European Fund, which seeks long-term growth of capital by investing
primarily in the common stocks of established companies in Western Europe,
provided shareholders with a total return of 13.37% (Class A Shares, without
sales charges) for the six months ended April 30, 1997.
 
Throughout the reporting period, European markets were supported by improvements
in economic growth, a continuation of relaxed monetary policies, low inflation
and further corporate restructuring that led to many positive earnings
surprises. The Fund's management team was able to take advantage of these trends
to a large extent, outperforming its benchmark while overcoming the effects of a
stronger dollar.
 
FUND BEGINS REDUCING FINANCIAL SECTOR HOLDINGS
 
The Fund began the period heavily weighted in financial and other interest-rate
sensitive sectors. This positioning resulted from the management team's positive
view of prospects for European Monetary Union and the downward pressure on
interest rates as countries sought to meet the Maastricht criteria. However, as
signs of stronger economic growth began to appear in late 1996 and early 1997,
the management team took profits on its interest rate-sensitive holdings in
favor of investments in companies it believed most likely to benefit from faster
growth.
 
Throughout the reporting period, the Fund maintained its emphasis on
restructuring companies, especially those with the potential to provide positive
earnings surprises. This focus proved beneficial as the general trend towards
restructuring picked up steam throughout the continent, especially in France and
Germany. The management team considers restructuring to be representative of a
sea change in the way European companies do business and, therefore, intends to
maintain a restructuring emphasis for the foreseeable future.
 
FUND EFFECTIVELY MANAGES CURRENCY RISK
 
Given that the Fund is U.S. dollar denominated, but invests primarily in
non-dollar securities, the growing strength of the dollar relative to most
European currencies was of primary importance to the management team. In
understanding the full impact of the rising dollar, remember that while it cuts
into the gains of U.S. investors after the effects of currency conversion are
taken into account, it also makes the American-bound exports of companies in
which the Fund invests more competitive. The management team's decision to use
currency hedges was an important factor in the Fund's performance in early 1997,
as were investments in companies it believed would benefit through exports.
 
As we've said before, this is an exciting time in Europe. Although there will
certainly be periods of uncertainty on the way to monetary union and the full
restructuring of European business, your management team maintains a bullish
outlook on the future and intends to help you profit from it.

Past performance is no guarantee of future results. Investment returns and
principal value will fluctuate so that an investor's shares, when redeemed, may
be worth more or less than the original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class A
shares of Vista European Fund, the Lipper European Equity Funds Average and the
MSCI Europe Index from 11/30/95 through 4/30/97. The Fund's performance includes
a 4.75% sales charge and assumes the reinvestment of all dividends and capital
gains. Also, certain fees were waived during the period. Had they not been
waived, total returns would have been lower.
 
The Lipper European Equity Funds Average represents the average performance of a
universe of 69 actively managed mutual funds that invest in European stocks.
Lipper is an independent mutual fund performance monitor whose results are based
on total return and do not reflect a sales charge.
 
The MSCI Europe Index is unmanaged and is a replica (or model) of the
performance of the European equity markets; return figures assume the
reinvestment of dividends. An individual cannot invest in the index.
 
International investing involves a greater degree of risk and increased
volatility. Changes in currency exchange rates and differences in accounting and
taxation policies outside the U.S. can raise or lower returns. Also, some
overseas markets may not be as politically and economically stable as the United
States and other nations.

VISTA SOUTHEAST ASIAN FUND
 
Vista Southeast Asian Fund, which seeks long-term growth of capital by investing
in the stocks of companies located in the Pacific Rim (excluding Japan), had a
total return of -0.04% (Class A shares, without sales charges) for the six-month
period ended April 30, 1997.
 
FUND FOCUSES ON COUNTRY SELECTION
 
The Fund benefited throughout the reporting period from a very careful approach
to country selection. Hong Kong and Malaysian companies, the region's best
performers, were overweighted during most of the period, although holdings in
Malaysia were reduced during the first four months of 1997. Perhaps more
importantly, the Fund avoided investments in the poorly-performing Thailand
market due to concern over that country's fiscal situation.
 
Another major factor in many Southeast Asian markets, during the latter part of
the reporting period, was the volatility in U.S. interest rates. With many of
these countries' rates tied closely to those in the US, the management team
believes a sustained advance may require a clarification of US interest rate
direction.
 
The management team is confident that the impending Chinese takeover of Hong
Kong, the region's largest market, should be relatively smooth given China's
stated desire to have Hong Kong retain its position as a center of global
commerce. In fact, the Fund ended the reporting period overweight in Hong Kong
based on attractive price-to-earnings growth characteristics.
 
SOUTHEAST ASIAN MARKETS NO LONGER MOVE IN TANDEM
 
The major lesson for investors during the period was in the performance
divergence among markets in the region. Gone are the days when Southeast Asian
markets rose and fell together, as countries' differing economic policies and
favored industries now cause their markets to perform in unique ways. This
divergence places a premium on the Fund's disciplined approach to country and
security selection.

This chart illustrates comparative performance for $10,000 invested in Class A
shares of Vista Southeast Asian Fund, the Lipper Pacific Ex-Japan Funds Average
and the MSCI Pacific Ex-Japan Index from 11/30/95 through 4/30/97. The Fund's
performance includes a 4.75% sales charge and assumes the reinvestment of all

Had they not been waived, total returns would have been lower.
 
The Lipper Pacific Ex-Japan Funds Average represents the average performance of
a universe of 86 actively managed mutual funds that invest in Asian stock

performance monitor whose results are based on total return and do not reflect a
sales charge.
 
The MSCI Pacific Ex-Japan Index is unmanaged and is a replica (or model) of the
performance of the Pacific region equity markets, excluding Japan. Total return
figures assume the reinvestment of dividends. An individual cannot invest in the
Index.
 
International investing involves a greater degree of risk and increased
volatility. Changes in currency exchange rates and differences in accounting and
taxation policies outside the U.S. can raise or lower returns. Also, some
overseas markets may not be as politically and economically stable as the United
States and other nations.

VISTA JAPAN FUND
 
Vista Japan Fund, which seeks long-term growth of capital by investing in the
stocks of companies located in Japan, provided shareholders with a total return
of 0.82% for the six months ended April 30, 1997 (Class A shares, without sales
charges).
 
OUTSTANDING PERFORMANCE IN A TOUGH MARKET
 
While the Fund's returns may appear minimal in comparison to those achieved
elsewhere in the world, it is quite impressive when one considers that the broad
Japanese market had a return of -7.05%, as measured by the Tokyo SE (Topix) 1st
Section Index.
 
This tremendous outperformance was achieved for two reasons. First, the
management team correctly anticipated that the yen would continue to weaken
against the dollar. It, therefore, made extensive use of currency hedging to
offset the negative effects of the falling yen on U.S. investors. The yen also
played a part in the second key performance driver, which was the management
team's focus on large Japanese exporting companies that tend to benefit when the
yen is relatively weak.
 
JAPANESE STOCKS FINALLY SHOW SIGNS OF A TURNAROUND
 
As the reporting period ended, Japanese stocks were finally beginning to show
signs of the long-awaited turnaround. However, the management team remains
highly cautious given its belief that the Japanese market continues to be caught
in a one step forward, two steps back mode and will ultimately require sustained
economic growth for a general advance.
 
Given this cautious view, the Fund ended the reporting period with a
broadly-diversified portfolio of Japanese securities and a significant amount of
protective currency and other hedges. Among the signs the management team is
looking for, before taking a more bullish stance, is widespread participation in
the profits currently being earned only by the largest companies.
 
Despite the fact that Japan's equity markets have performed poorly for the past
few years, the management team continues to be attracted by Japan's unique
strengths: the world's second-largest economy, strong corporations, a
highly-educated population and its unparalleled access to the world's
fastest-growing economies.

VISTA INTERNATIONAL EQUITY FUND
 
Vista International Equity Fund, which seeks long-term growth of capital by
investing in the common stocks of established overseas companies, provided
shareholders with a total return of 4.55% (Class A shares, without sales
charges) for the six months ended April 30, 1997.
 
FUND MAINTAINS ITS OVERWEIGHTING IN EUROPE
 
During a generally positive period for international equities, the Fund was able
to outperform its benchmark by overweighting European equities while limiting
exposure to the poorly-performing Japanese market.
 
Within Europe, markets were bolstered by improvements in economic growth, a
continuation of relaxed monetary policies, low inflation and further corporate
restructuring that led to many positive earnings surprises. The restructuring
theme, in particular, remained evident in the Fund's holdings and was beneficial
to overall performance.
 
Moving forward, the management team believes that the resumption of strong
economic growth will be essential for progress in the Japanese equity markets.
Until such growth is evident, the Fund will remain underweight in the country's
securities.
 
MANAGEMENT TEAM CONTINUES TO BUILD POSITIONS IN LATIN AMERICA AND SOUTHEAST ASIA
 
With Latin American markets performing well, the Fund added to its positions in
the region. In doing so, it focused on companies the management team believes
will benefit from the ongoing process of economic reform. A slightly-overweight
position was also maintained in Southeast Asia, with specific emphasis on Hong
Kong-based companies, which the management team believes are well-positioned on
a valuation basis. In both Latin America and Southeast Asia, a high degree of
selectivity is being applied to both country and individual security decisions.
 
The management team believes that international markets offer long-term U.S.
investors significant opportunities for capital appreciation. Using Vista's
disciplined international stock management system, which includes tools that
help smooth out the effects of currency fluctuations, the Fund will continue to
be a source for a diversified portfolio of high-quality overseas investments.

Past performance is not predictive of future performance. Investment return and
principal value will fluctuate with market conditions. When shares are redeemed,
they may be worth more or less than their original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class A
shares of Vista International Equity Fund, the Lipper International Funds
Average and the MSCI EAFE Index from 12/31/92 to 4/30/97. The Fund's performance
includes a 4.75% sales charge and assumes the reinvestment of all dividends and
capital gains. Also, certain fees were waived during the period. Had they not
been waived, total returns would have been lower. The Fund commenced operations
on 12/31/92. Class B Shares were introduced on 11/15/93. Investors should note
that information presented for Class B prior to their introduction is based upon
historical expenses of the predecessor Class A Shares, which are lower than the
actual expenses of the Class B Shares. Additionally, annualized figures have
been restated to reflect the maximum 5% contingent deferred sales charge that
applies to the Fund's B Shares.
 
The Lipper International Funds Average represents the average performance of a
universe of 375 actively managed international stock funds. Lipper is an
independent mutual fund performance monitor whose results are based on total
return and do not reflect a sales charge.
 
The MSCI EAFE (Europe, Australia, Far East) Index is unmanaged and is a replica
(or model) of the performance of the world's equity markets, excluding the U.S.
and Canada. An individual cannot invest in the Index.
 
International investing involves special risks. Changes in currency exchange
rates and differences in accounting and taxation policies outside the U.S. can
raise or lower returns. Also, some overseas markets may not be as politically
and economically stable as the U.S. or other nations.

VISTA MUTUAL FUNDS
 
NOTES TO FINANCIAL STATEMENTS April 30, 1997 (unaudited)
- --------------------------------------------------------------------------------
1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES -- Mutual Fund Group (the
"Trust") was organized on May 11, 1987 as a Massachusetts Business Trust, and is
registered under the Investment Company Act of 1940, as amended, (the "1940
Act") as an open-end management investment company. Vista European Fund ("VEF"),
Vista Southeast Asian Fund ("VSEAF"), Vista Japan Fund ("VJF") and Vista
International Equity Fund ("VIEF") collectively, the "Funds", are four separate
series of the Trust. VEF, VSEAF and VJF commenced operations on November 2,
1995. The Funds each offer two classes of shares. Class A shares generally
provide for a front-end sales charge while Class B shares provide for a
contingent deferred sales charge. All classes of shares have equal rights as to
earnings, assets and voting privileges except that each class may bear different
distribution fees and each class has exclusive voting rights with respect to its
distribution plan.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.
 
The following is a summary of significant accounting policies followed by the
Funds:
 
    A.   VIEF
 
    Since inception, the VIEF has utilized the Master Feeder Fund Structure.
    VIEF seeks to achieve its investment objective by investing all of its
    investable assets of the Fund in the International Equity Portfolio, (the
    "Portfolio"). The Portfolio, like the Fund, is an open-end management
    investment company having the same investment objectives as the Fund. As of
    April 30, 1997 VIEF owned 99.99% of the Portfolio. The financial statement
    of the Portfolio, including the portfolio of investments, are included
    elsewhere in this report and should be read in conjunction with the
    financial statements of the Fund.
 
       1.   Valuation of Investments -- VIEF records its investment in the
       Portfolio at value. Securities of the Portfolio are recorded at value as
       more fully discussed in the notes to those financial statements.
 
       2.   Foreign Currency Translations -- The books and records of the
       Portfolio are maintained in U.S. dollars, the foreign currency
       translation policy is more fully discussed in the notes to those
       financial statements.
 
       3.   Investment Income -- VIEF records daily its pro-rata share of the
       Portfolio's income, expenses, and realized and unrealized gains and
       losses. In addition, the Fund accrues its own expenses daily as incurred.
       Realized gain/losses and changes in unrealized appreciation/depreciation
       represent the Fund's share of such elements allocated from the Portfolio.
 
    B.   VEF, VSEAF and VJF
 
       1.   Valuation of Investments -- Equity securities, purchased options and
       futures are valued at the last sale price on the exchange on which they
       are primarily traded, including the NASDAQ National Market. Securities
       for which sale prices are not available and other over-the-counter
       securities are valued at the last quoted bid price. Bonds and other fixed
       income securities (other than short-term obligations), including listed
       issues, are valued on the basis of valuations supplied by pricing
       services or by matrix pricing systems of a major dealer in bonds.
       Short-term debt securities with 61 days or more to maturity at time of
       purchase are valued, through the 61st day prior to maturity, at market
       value based on quotations obtained from market makers or other
       appropriate sources; thereafter, the value on the 61st day is amortized
       on a straight-line basis over the remaining number of days to maturity.
       Short-term investments with 60 days or less to maturity at time of
       purchase are valued at amortized cost, which approximates market.
       Portfolio securities for which there are no such quotations or valuations
       are valued at fair value as determined in good faith by or at the
       direction of the Trustees.
 
       2.   Repurchase Agreements -- It is the Trust's policy that repurchase
       agreements are fully collateralized by U.S. Treasury and Government
       Agency securities. All collateral is held by the Trust's custodian bank,
       subcustodian, or a bank with which the custodian bank has entered into a
       subcustodian agreement, or is segregated in the Federal Reserve Book
       Entry System. In connection with transactions in repur-

       chase agreements, if the seller defaults and the value of the collateral
       declines, or if the seller enters an insolvency proceeding, realization
       of the collateral by the Trust may be delayed or limited.
 
       3.   Futures Contracts -- When a fund enters into a futures contract, it
       makes an initial margin deposit in a segregated account, either in cash
       or liquid securities. Thereafter, the futures contract is marked to
       market and the fund makes (or receives) additional cash payments daily to
       the broker. Changes in the value of the contract are recorded as
       unrealized appreciation/depreciation until the contract is closed or
       settled.
 
       The Funds may enter into futures contracts only on exchanges or boards of
       trade. The exchange or board of trade acts as the counterparty to each
       futures transaction, therefore, the Fund's credit risk is limited to
       failure of the exchange or board of trade.
 
       The Funds invest in stock index futures contracts for the purpose of
       hedging the Fund against share price volatility, which purpose may or may
       not be achieved. When the Fund is not fully invested in the securities
       market, it may enter into "long" positions in futures or options
       contracts in order to gain rapid market exposure that may in part or
       entirely offset increases in the cost of securities intended for
       purchase. Use of futures contracts subject the Fund to risk of loss in
       excess of amounts shown on the Statement of Assets and Liabilities, up to
       the amount of the value of the futures contracts as shown in the
       Portfolio of Investments at April 30, 1997.
 
       4.   Written Options -- When a fund writes an option on a futures
       contract, an amount equal to the premium received by the fund is included
       in the fund's Statement of Assets and Liabilities as an asset and
       corresponding liability. The amount of the liability is adjusted daily to
       reflect the current market value of the written option and the change is
       recorded in a corresponding unrealized gain or loss account. When a
       written option expires on its stipulated expiration date, or when a
       closing transaction is entered into, the related liability is
       extinguished and the fund realizes a gain (or loss if the cost of the
       closing transaction exceeds the premium received when the option was
       written).
 
       The Funds write options on stock index securities futures. These options
       are settled for cash and subject the Funds to market risk in excess of
       the amounts that are reflected in the Statement of Assets and
       Liabilities. The Funds, however, are not subject to credit risk on
       written options as the counterparty has already performed its obligation
       by paying a premium at the inception of the contract.
 
       As of April 30, 1997 the Funds had no outstanding written options.
 
       5.   Foreign Currency Translation -- The books and records of the Funds
       are maintained in U.S. dollars. Foreign currency amounts are translated
       into U.S. dollars at the official exchange rates, or at the mean of the
       current bid and asked prices, of such currencies against the U.S. dollar
       as quoted by a major bank, on the following basis:
 
            a.   Market value of investment securities and other assets and
            liabilities: at the closing rate of exchange at the balance sheet
            date.
 
            b.   Purchases and sales of investment securities, income and
            expenses: at the rates of exchange prevailing on the respective
            dates of such transactions.
 
       Although the net assets of the Funds are presented at the foreign
       exchange rates and market values at the close of the periods, the Funds
       do not isolate that portion of the results of operations arising as a
       result of changes in the foreign exchange rates from the fluctuations
       arising from changes in the market prices of securities held during the
       year. Similarly, the Funds do not isolate the effect of changes in
       foreign exchange rates from the fluctuations arising from changes in the
       market prices of long-term debt securities sold during the year.
       Accordingly, such realized foreign currency gains (losses) are included
       in the reported net realized gains (losses) on security transactions.
 
       Reported realized foreign exchange gains or losses arise from disposition
       of foreign currency, currency gains or losses realized between the trade
       and settlement dates on securities transactions, and the difference
       between the amounts of dividends, interest, and foreign withholding taxes
       recorded on the Funds' books on the transaction date and the U.S. dollar
       equivalent of the amounts actually received or

       paid. Unrealized foreign exchange gains and losses arise from changes
       (due to the changes in the exchange rate) in the value of foreign
       currency and other assets and liabilities denominated in foreign
       currencies which are held at period end.
 
       6.   Forward Foreign Currency Exchange Contracts -- The Funds may enter
       into forward foreign currency contracts (obligations to purchase or sell
       foreign currency in the future on a date and price fixed at the time the
       contracts are entered into) to hedge the fund against fluctuations in the
       value of its assets or liabilities due to change in the value of foreign
       currencies. Each day the forward contract is open, changes in the value
       of the contract are recognized as unrealized gains or losses by "marking
       to market". When the forward contract is closed, or the delivery of the
       currency is made or taken, the Fund records a realized gain or loss equal
       to the difference between the proceeds from (or cost of) the closing
       transaction and the fund's basis in the contract. The Funds are subject
       to off-balance sheet risk to the extent of the value of the contracts for
       purchases of currency and in an unlimited amount for sales of currency.
 
       7.   Security Transactions and Investment Income -- Investment
       transactions are accounted for on the trade date (the date the order to
       buy or sell is executed). Securities gains and losses are calculated on
       the identified cost basis. Interest income is accrued as earned. Dividend
       income is recorded on the ex-dividend date.
 
    C.   General Policies
 
       1.   Organization Costs -- Organization and initial registration costs
       incurred in connection with establishing the VIEF have been deferred and
       are being amortized on a straight-line basis over a sixty month period
       beginning at the commencement of operations of each Fund.
 
       2.   Federal Income Taxes -- Each Fund is treated as a separate taxable
       entity for Federal income tax purposes. The Trust's policy is to comply
       with the provisions of the Internal Revenue Code applicable to regulated
       investment companies and to distribute to shareholders all of its
       distributable net investment income, and net realized gain on
       investments. In addition, the Trust intends to make distributions as
       required to avoid excise taxes. Accordingly, no provision for Federal
       income or excise tax is necessary.
 
       3.   Distributions to Shareholders -- Dividends and distributions paid to
       shareholders are recorded on the ex-dividend date. The amount of
       dividends and distributions from net investment income and net realized
       capital gains is determined in accordance with Federal income tax
       regulations, which may differ from generally accepted accounting
       principles. To the extent these "book/tax" differences are permanent in
       nature, (i.e., that they result from other than timing of recognition --
       "temporary differences") such amounts are reclassified within the capital
       accounts based on their Federal tax-basis treatment. The adjustments for
       the Funds relate primarily to the character for tax purposes of certain
       short-term gains or losses. Dividends and distributions which exceed net
       investment income or net realized capital gains for financial reporting
       purposes but not for tax purposes are reported as distributions in excess
       of net investment income or net realized capital gains.
 
       4.   Expenses -- Expenses of the Trust directly attributable to a Fund
       are charged to that Fund; other expenses are allocated proportionately
       among each Fund within the Trust in relation to the net assets of each
       Fund or on another reasonable basis. In calculating the net asset value
       per share of each class, investment income, realized and unrealized gains
       and losses and expenses other than class specific expenses, are allocated
       daily to each class of shares based upon the proportion of net assets of
       each class at the beginning of each day.
 
2.   FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
    A.   Investment Advisory Fee -- Pursuant to separate Investment Advisory
    Agreements, The Chase Manhattan Bank, ("Chase" or the "Adviser") acts as the
    Investment Adviser to the VEF, VSEAF and VJF. Chase is a direct wholly-owned

    sub-administration services to the Trust, including providing officers,

    daily net assets of each Fund. The Trustees have adopted Distribution Plans
    (the "Distribution Plans") for Class A and B shares of the funds in
    accordance with Rule 12b-1 under the 1940 Act. The Class A Distribution
    Plans provide that each Fund shall pay distributions fees, including
    payments to the Distributor, at annual rates not to exceed 0.25% of the
    average daily net assets of the Class A Shares of each Fund for distribution
    services. The Class B Distribution Plan provides that each Fund shall pay
    distribution fees, including payments to the Distributor, at an annual rate
    not to exceed 0.75% of the average annual net assets of the Class B Shares
    for distribution services.
 
    The Distributor voluntarily waived all or a portion of sub-administration
    fees as outlined in Note 2.E. below.
 
    D.   Administration Fee -- Pursuant to an Administration Agreement, Chase
    (the "Administrator") provides certain administration services to the Trust.

    VSEAF, and VJF a fee computed at the annual rate equal to 0.10% of the
    respective Fund's average daily net assets and from VIEF at the annual rate

NOTES TO FINANCIAL STATEMENTS April 30, 1997 (unaudited) (continued)
- --------------------------------------------------------------------------------
 
8.   CONCENTRATIONS -- At April 30, 1997, substantially all of the Fund's net
assets consist of securities of issuers which are denominated in foreign
currencies. Changes in currency exchange rates will affect the value of and
investment income from such securities. Substantially all of VSEAF's net assets
consists of securities which are subject to greater price volatility, limited
capitalization and liquidity, and higher rates of inflation than securities of
companies based in the United States. In addition, certain Asian securities may
be subject to substantial governmental involvement in the economy and greater
social economic and political uncertainty.
 
9.   RETIREMENT PLAN -- The Funds have adopted an unfunded noncontributory
defined benefit pension plan covering all independent trustees of the Funds who
will have served as independent trustees for at least five years at the time of
retirement. Benefits under this plan are based on compensation and years of
service. Pension expenses for the six months ended April 30, 1997, included in
Trustees Fees and Expenses in the Statement of Operations, and accrued pension
liability included in other accrued liabilities, respectively, in the Statement
of Assets and Liabilities were as follows:

NOTES TO FINANCIAL STATEMENTS April 30, 1997 (unaudited)
- --------------------------------------------------------------------------------
1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES -- International Equity
Portfolio ("the Portfolio") is separately registered under the Investment
Company Act of 1940, as amended, as a non-diversified, open end management
investment company organized as a trust under the laws of the State of New York.
The declaration of trust permits the Trustees to issue beneficial interests in
the Portfolio. The Portfolio commenced operations on December 29, 1992.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.
 
    The following is a summary of significant accounting policies followed by
    the Portfolio:
 
    A.   Valuation of Investments -- Equity securities, purchased options and
    futures are valued at the last sale price on the exchange on which they are
    primarily traded, including the NASDAQ National Market. Securities for which
    sale prices are not available and other over-the-counter securities are
    valued at the last quoted bid price. Bonds and other fixed income securities
    (other than short-term obligations), including listed issues, are valued on
    the basis of valuations supplied by pricing services or by matrix pricing
    systems of a major dealer in bonds. Short-term debt securities with 61 days
    or more to maturity at time of purchase are valued, through the 61st day
    prior to maturity, at market value based on quotations obtained from market
    makers or other appropriate sources; thereafter, the value on the 61st day
    is amortized on a straight-line basis over the remaining number of days to
    maturity. Short-term investments with 60 days or less to maturity at time of
    purchase are valued at amortized cost, which approximates market. Portfolio
    securities for which there are no such quotations or valuations are valued
    at fair value as determined in good faith by or at the direction of the
    Trustees.
 
    B.   Repurchase Agreements -- It is the Trust's policy that repurchase
    agreements are fully collateralized by U.S. Treasury and Government Agency
    securities. All collateral is held by the Trusts' custodian bank,
    subcustodian, or a bank with which the custodian bank has entered into a
    subcustodian agreement, or is segregated in the Federal Reserve Book Entry
    System. In connection with transactions in repurchase agreements, if the
    seller defaults and the value of the collateral declines, or if the seller
    enters an insolvency proceeding, realization of the collateral by the Trusts
    may be delayed or limited.
 
    C.   Forward Foreign Currency Exchange Contracts -- The Portfolio may enter
    into forward foreign currency contracts (obligations to purchase or sell
    foreign currency in the future on a date and price fixed at the time the
    contracts are entered into) to hedge the Portfolio against fluctuations in
    the value of its assets or liabilities due to change in the value of foreign
    currencies. Each day the forward contract is open, changes in the value of
    the contract are recognized as unrealized gains or losses by "marking to
    market". When the forward contract is closed, or the delivery of the
    currency is made or taken, the Portfolio records a realized gain or loss
    equal to the difference between the proceeds from (or cost of) the closing
    transaction and the Portfolio's basis in the contract. The Portfolio is
    subject to off-balance sheet risk to the extent of the value of the
    contracts for purchases of currency and in an unlimited amount for sales of
    currency.
 
    D.   Foreign Currency Translation -- The books and records of the Portfolio
    are maintained in U.S. dollars. Foreign currency amounts are translated into
    U.S. dollars at the official exchange rates, or at the mean of the current
    bid and asked prices, of such currencies against the U.S. dollar as quoted
    by a major bank, on the following basis:
 
       1.   Market value of investment securities and other assets and
       liabilities: at the closing rate of exchange at the balance sheet date.
 
       2.   Purchases and sales of investment securities, income and expenses:
       at the rates of exchange prevailing on the respective dates of such
       transactions.
 
    Although the net assets of the Portfolio are presented at the foreign
    exchange rates and market values at the close of the periods, the Portfolio
    does not isolate that portion of the results of operations arising as a
    result of changes in the foreign exchange rates from the fluctuations
    arising from changes in the market prices of securities sold during the
    year. Accordingly, realized foreign currency gains (losses) are included in
    the reported net realized losses on security transactions.

NOTES TO FINANCIAL STATEMENTS April 30, 1997 (unaudited) (continued)
- --------------------------------------------------------------------------------
 
    Reported realized foreign exchange gains or losses arise from disposition of
    foreign currency, currency gains or losses realized between the trade and
    settlement dates on securities transactions, and the difference between the
    amounts of dividends, interest, and foreign withholding taxes recorded on
    the Portfolio's books on the transaction date and the U.S. dollar equivalent
    of the amounts actually received or paid. Unrealized foreign exchange gains
    and losses arise from changes (due to the changes in the exchange rate) in
    the value of foreign currency and other assets and liabilities denominated
    in foreign currencies which are held at period end.
 
    E.   Futures Contracts -- When the Portfolio enters into a futures contract,
    it makes an initial margin deposit in a segregated account, either in cash
    or liquid securities. Thereafter, the futures contract is marked to market
    and the Portfolio makes (or receives) additional cash payments daily to the
    broker. Changes in the value of the contract are recorded as unrealized
    appreciation/depreciation until the contract is closed or settled.
 
    The Portfolio invested a portion of its liquid assets in long stock index
    futures contracts to more fully participate in the market. Use of futures
    contracts subject the Portfolio to risk of loss in excess of amounts shown
    on the Statement of Assets and Liabilities, up to the amount of the value of
    the contract.
 
    The Portfolio may enter into futures contracts only on exchanges or boards
    of trade. The exchange or board of trade acts as the counterparty to each
    futures transaction, therefore, the Portfolio's credit risk is limited to
    failure of the exchange or board of trade.
 
    As of April 30, 1997, the Portfolio held futures contracts as listed in the
    Portfolio of Investments.
 
    F.   Written Options -- When the Portfolio writes an option on a futures
    contract, an amount equal to the premium received by the Portfolio is
    included in the Portfolio's Statement of Assets and Liabilities as an asset
    and corresponding liability. The amount of the liability is adjusted daily
    to reflect the current market value of the written options and the change is
    recorded in a corresponding unrealized gain or loss account. When a written
    option expires on its stipulated expiration date, or when a closing
    transaction is entered into, the related liability is extinguished and the
    Portfolio realizes a gain (or loss if the cost of the closing transaction
    exceeds the premium received when the option was written).
 
    The Portfolio writes options on stock index securities futures. These
    options are settled for cash and subject the Portfolio to market risk in
    excess of the amounts that are reflected in the Statement of Assets and
    Liabilities. The Portfolio, however, is not subject to credit risk on
    written options as the counterparty has already performed its obligation by
    paying a premium at the inception of the contract.
 
    As of April 30, 1997 the Portfolio had no outstanding written options.
 
    G.   Security Transactions and Investment Income -- Investment transactions
    are accounted for on the trade date (the date the order to buy or sell is
    executed). Securities gains and losses are calculated on the identified cost
    basis. Interest income is accrued as earned. Dividend income is recorded on
    the ex-dividend date.
 
    H.   Organization Costs -- Organization and initial registration costs
    incurred in connection with establishing the Portfolio have been deferred
    and are being amortized on a straight-line basis over a sixty month period
    beginning at the commencement of operations of the Portfolio.
 
    I.   Federal Income Taxes -- The Portfolio intends to continue qualify as a
    partnership and therefore net income and net realized gains are taxed to the
    partners. Accordingly, no tax provision is recorded by the Portfolio. The
    investors in the Portfolio must take into account their proportionate share
    of the Portfolio's income, gains, losses, deductions, credits and tax
    preference items in computing their federal income tax liability, without
    regard to whether they have received any cash distributions from the
    Portfolio. The Portfolio does not intend to distribute to investors its net
    investment income or its net realized gains, if any. It is intended that the
    Portfolio will be managed in such a way that investors in the Portfolio will
    be able to satisfy the requirements of subchapter M of the Internal Revenue
    Code to be taxed as regulated investment companies.

2.   FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
    A.   Investment Advisory Fee -- Pursuant to an Investment Advisory
    Agreement, The Chase Manhattan Bank, ("Chase" or the "Adviser") acts as the
    Investment Adviser to the Portfolio. Chase is a direct wholly-owned
    subsidiary of The Chase Manhattan Corporation. As Investment Adviser, Chase
    supervises the investments of the Portfolio and for such services is paid a

Dear Shareholder:
 
We are pleased to present this Semi-Annual Report for the following Vista U.S.
Equity Funds for the six months ending April 30, 1997:
 
<TABLE>
    <S>                              <C>
    - American Value Fund            - Growth & Income Fund
    - Balanced Fund                  - Large Cap Equity Fund
    - Capital Growth Fund            - Small Cap Equity Fund
    - Equity Income Fund
</TABLE>
 
POSITIVE ECONOMIC FACTORS DRIVE U.S. STOCKS HIGHER
 
The environment for equities during the period was quite positive, as a
combination of buoyant economic growth, strong corporate earnings and low
inflation drove stock prices higher. The largest U.S. stocks continued to lead
the way, with the S&P 500 Index of large company stocks posting a 14.71% gain
during the period. These outstanding returns, however, were not equaled further
down the capitalization curve as the S&P Mid Cap 400 Index had a 6.88% gain and
the Russell 2000 Index of smaller company stocks returned just 1.61%. This
performance divergence was intensified by the high levels of market volatility,
which caused investors to favor the blue chips as a defensive measure, as well
as by the increasing use of S&P 500 Index funds, which by their nature created
heavy demand for the stocks in the index.
 
BOND MARKETS ONCE AGAIN EXPERIENCE VOLATILITY
 
U.S. fixed income markets remained sensitive to fears, as yet unrealized, that
the high levels of economic growth would prove inflationary. Although interest
rates were falling in response to moderating economic growth as the period
began, the trend reversed in early 1997 as stronger economic growth reports were
issued. Rates peaked around the time the Federal Reserve Board raised interest
rates on March 25th.
 
Regardless of which direction the markets take over the short term, we share
your enthusiasm for investing in the future of corporate America. Our portfolio
management team has worked hard to provide you with investments to help you
reach your financial goals, and will continue to do so in the future. We thank
you for the trust you've placed in Vista, and encourage you to call us at
1-800-34-VISTA if you have any questions.
 
Sincerely,
/s/ Fergus Reid

Chairman

VISTA GROWTH AND INCOME FUND
 
Vista Growth and Income Fund, which seeks capital growth and current income by
investing primarily in common stocks, had a total return of 10.10% (Class A
shares, without sales charges) for the six month period ended April 30, 1997.
 
SECTOR AND INDIVIDUAL STOCK DECISIONS KEY TO PERFORMANCE
 
During the reporting period, the Fund's performance was supported by effective
sector allocations. In late 1996, the Fund benefited from its overweight
positions in financial and technology stocks, but the management team
subsequently began cutting the financial exposure due to less-compelling
valuations. The technology overweight was maintained, however, with specific
emphasis on communications, networking and software companies.
 
As the reporting period progressed, the management team correctly anticipated
that economic growth would accelerate and, therefore, began favoring companies
in sectors such as capital goods, which tend to do well in a growing economy.
Exposure to the energy sector was also increased based on more attractive
valuations.
 
MID-CAP STOCKS CONTINUE TO LAG
 
Exposure to mid-cap stocks has always been a unique characteristic of the Fund
and, in the past, these mid-cap investments have typically supported overall
performance. During this reporting period in which large caps dominated,
however, the Fund's mid-cap holdings held back performance. The management team
continues to believe that mid-cap stocks are attractively valued and, over the
long term, should outperform.
 
Expecting economic growth to moderate as 1997 progresses, the management team is
placing particular emphasis on companies which it believes can maintain
profitability in a slower-growth environment.

VISTA CAPITAL GROWTH FUND
 
Vista Capital Growth Fund, which seeks to provide capital growth through a
portfolio that consists primarily of the common stocks of mid-sized companies,
posted a total return of 4.73% for the six months ended April 30, 1997 (Class A
shares, without sales charge).
 
The Fund was affected by the high levels of volatility among small- and mid-cap
stocks during the reporting period, but still managed to provide shareholders
with a solid, positive return. This was achieved through effective sector
positioning and individual stock selection.
 
FINANCIAL AND TECHNOLOGY STOCKS KEY TO LATE 1996 PERFORMANCE
 
The Fund began the period benefiting strongly from overweight positions in the
financial and technology sectors, positions which were taken based on the
management team's belief that economic growth would slow in the fall of 1996.
Vista's stock selection system proved especially helpful in the technology area,
as the Fund profited from holdings which had been purchased at attractive prices
during last summer's volatility.
 
As 1996 ended with the management team expecting accelerating economic growth,
the Fund began taking profits on its technology holdings and also reducing
exposure to financial stocks. Many of these assets were repositioned in cyclical
sectors such as capital goods. This shift was based on valuation concerns as
well as the fact that, historically, interest-rate sensitive sectors (i.e.,
financials) tend to suffer in a stronger economy while cyclical sectors have
historically outperformed.
 
FUND MAINTAINS A STRICT VALUE DISCIPLINE
 
As small- and mid-cap stocks experienced widespread weakness in early 1997, the
Fund maintained its strict value discipline. The management team took advantage
of falling stock prices to purchase what it believed were high-quality stocks at
newly-attractive prices, particularly in the technology area. Underlying many of
the investment selections was the belief that the market will eventually reward
companies exhibiting the ability to maintain earnings growth, especially in the
moderating economic environment Vista's research forecasts for later in 1997.
 
As the reporting period ended, small- and mid-cap stock prices had begun
recovering and were beginning to show signs of re-establishing their historic
market leadership. Although the Fund has performed very well during the
large-cap dominated rally that began in 1995, the management team believes it is
particularly well positioned for an environment that focuses more intensively on
valuation and visible earnings growth.

VISTA SMALL CAP EQUITY FUND
 
Vista Small Cap Equity Fund, which seeks capital growth by investing in small
cap common stocks, had a total return of -4.73% (Class A Shares, without sales
charges) for the six months ended April 30, 1997.
 
MANAGING IN A DIFFICULT PERIOD FOR SMALLER STOCKS
 
Although the Fund has been an outstanding performer since its inception in 1995,
it was unable to overcome the weakness in small cap issues during the reporting
period. The market was particularly harsh in March of 1997, when it uniformly
punished small company stocks with little regard for individual companies'
business prospects. Relying on Vista's disciplined five-step stock management
system, the management team was able to take advantage of the volatility to buy
what it believed were high-quality companies at newly-attractive prices.
 
The Fund began the period reducing a large cash position created by strong
investor interest, and throughout the period maintained relative diversification
by industry sector. As small cap prices fell, however, the manager was able to
increase holdings in growth-oriented technology and health care companies whose
prices had previously been too high for the Fund to purchase given its focus on
undervalued stocks.
 
As the reporting period ended, small-cap stock prices had begun recovering and
were beginning to show signs of re-establishing their historic market
leadership. Going forward, the management team believes that compelling
valuations make this an outstanding time for small cap investments.
 
FUND CLOSES TO NEW INVESTORS
 
With the Fund reaching $500 million in assets, it was closed to new investors on
January 20, 1997. This action was taken, in accordance with the Fund's
prospectus, to ensure that the manager has sufficient flexibility in the small
cap market.

VISTA EQUITY INCOME FUND
 
The Vista Equity Income Fund, which seeks to provide current income plus
opportunities for capital growth by investing primarily in income-producing
equity securities, delivered a total return of 12.74% for the six months ended
April 30, 1997 (Class A shares, without sales charge).
 
REITs HELPED FUND DELIVER INCOME & CAPITAL APPRECIATION
 
The Fund was successful in achieving its objective through the use of a barbell
strategy. Using this strategy, the management team invests in two types of
securities: those with high dividend yields as well as those which the
management team believes offer the potential for capital appreciation.
 
The Fund began the reporting period with a continued overweight position in Real
Estate Investment Trusts (REITs), which helped the Fund gain both high income
and capital appreciation for most of 1996. By the end of the year, however, the
management team had begun cutting REIT exposure as many of these holdings had
reached Vista's 1997 price targets.
 
FUND RE-FOCUSED FOR FASTER GROWTH IN EARLY 1997
 
Early in 1997, correctly anticipating accelerating economic growth, the
management team completed a shift from interest rate-sensitive sectors such as
financials and REITs to those which tend to perform better in a growing economy.
Additionally, on a valuation basis, the Fund began rebuilding its exposure to
the energy sector. While these energy holdings have lagged the market, their
valuations remain attractive given individual company considerations.
 
The management team expects that volatility will continue to define the stock
market. In such an environment, the Fund's barbell strategy is particularly
useful for overall total return because high levels of income can help offset
falling prices. At the same time, Vista's disciplined stock management system
identifies attractively-valued companies which provide the potential for capital
appreciation.

the Standard & Poor's 500 Stock Index from July 31, 1993 through April 30, 1997.
The Fund's performance includes a 4.50% sales charge and assumes the
reinvestment of all dividends and capital gains. The Fund commenced operations
on 7/15/93. Class B Shares were introduced on 5/6/96. Investors should note that
information presented for Class B Shares prior to their introduction is based
upon historical expenses of the predecessor Class A Shares, which are lower than
the actual expenses of the Class B Shares. Additionally, annualized figures have
been restated to reflect the maximum 5% contingent deferred sales charge that
applies to the Fund's B Shares. Also, certain fees were waived during the
period. Had they not been waived, total returns would have been lower.
 
The Lipper Equity Income Funds Average represents the average performance of a
universe of 181 actively managed mutual funds that invest in income-producing
equity securities. Lipper is an independent mutual fund performance monitor
whose results are based on total return and do not reflect a sales charge.

VISTA LARGE CAP EQUITY FUND
 
Vista Large Cap Equity Fund, which seeks to provide capital growth through a
portfolio of large cap common stocks, provided shareholders with a total return
of 11.16% (Class A shares, without sales charges) for the six months ended April
30, 1997.
 
MARKET ENVIRONMENT FAVORS LARGE CAP COMPANIES
 
The Fund participated strongly in a market environment that favored the largest
companies. In late 1996, the Fund benefited from its overweight positions in
financial and technology stocks, but the management team subsequently began
cutting the financial exposure due to less-compelling valuations. The technology
overweight was maintained, however, with specific emphasis on communications,
networking and software companies.
 
As the reporting period progressed, the management team correctly anticipated
that economic growth would accelerate and, therefore, began favoring companies
in sectors such as capital goods, which tend to do well in a growing economy.
Exposure to the energy sector was also increased based on more attractive
valuations.
 
MANAGEMENT TEAM MAINTAINS FOCUS ON VALUATION
 
While the Fund has clearly benefited from the market's large cap bias, the
management team has continued to apply Vista's disciplined five-step stock
management system to help protect shareholders against overpaying for individual
holdings. By maintaining a widely-diversified approach and focusing on
individual stock selection, the management team looks to use periods of
volatility to buy high-quality holdings at what it believes are attractive
prices.

VISTA AMERICAN VALUE FUND
 
Vista American Value Fund, which seeks to maximize total return by investing in
a portfolio of well-established U.S. company equity securities, provided
shareholders with a total return of 6.08% for the six-month period ended April
30, 1997.
 
LARGEST US STOCKS POST STRONGEST PERFORMANCE
 
Over the past six months, investors continued to concentrate their purchases in
a select group of the largest, most liquid stocks in the S&P 500, and these
companies continued to produce the strongest gains during the period.
 
This performance disparity resulted in a significant divergence in the
underlying valuations of many individual stocks. As a group, the largest 100
companies in the S&P 500 Index, which includes many of the largest consumer
non-durable and technology companies, were selling at more than 19 times
earnings, over five times book value and almost two-and-a-half times sales. The
advisor to the Fund did not consider these valuations attractive in relation to
the group's long-term earnings capability. As such, the Fund did not have
significant exposure to this select group, causing its lag against the S&P 500,
which returned 14.71% for the period.
 
This contrasts with the smallest 100 companies in the S&P 500, many of which are
well-established, more economically sensitive businesses. As a group, these
companies were selling for ten times earnings, a little over two times book
value and about one times sales. The Fund's advisor considered these valuations
more attractive relative to long-term earning capability. This resulted in the
Fund being overweight in areas such as basic materials, financial services and
consumer cyclicals.
 
On April 30, common stocks represented 90.2% of the portfolio, which was
diversified among 44 issues in 11 broad economic sectors. The top five stock
holdings at period end included Allstate, Supervalu, Louisiana Pacific, Stratus
Computer and Merck.
 
A FOCUS ON POTENTIAL LONG-TERM PRICE APPRECIATION
 
Fund holdings are selected for their long-term potential and are often unpopular
with other investors. In some cases, considerable time may elapse before their
values are recognized by other investors, which can result in these issues
becoming market leaders. The Fund's advisor continues to seek attractive issues
in the capital goods, communication services and consumer cyclical sectors.

VISTA BALANCED FUND
 
Vista Balanced Fund, which seeks to provide capital growth plus current income
by investing in a portfolio of high-quality stocks, bonds and convertible
securities, had a total return of 6.38% (Class A shares, without sales charges)
for the six months ended April 30, 1997.
 
SLIGHT ALLOCATION SHIFTS SEEK TO INCREASE RETURNS
 
The Fund's management team made tactical shifts throughout the reporting period
to capitalize on the changing relative values of stocks, bonds and cash.
 
On the equity side, the Fund's performance was supported by effective sector
allocations. In late 1996, the Fund benefited from its overweight positions in
financial and technology stocks, but the management team subsequently began
cutting the financial exposure due to less-compelling valuations. The technology
overweight was maintained, however, with specific emphasis on communications,
networking and software companies.
 
As the reporting period progressed, the management team correctly anticipated
that economic growth would accelerate and, therefore, began favoring companies
in cyclical sectors such as capital goods which tend to do well in a growing
economy. Exposure to the energy sector was also increased based on more
attractive valuations.
 
MORTGAGE-BACKED AND CORPORATE SECURITIES EMPHASIZED
 
On the fixed-income side, the Fund began the reporting period with a slight
overweighting of mortgage-backed securities as well as selected corporate
securities. This emphasis helped the Fund perform well as mortgages and
corporates were the top-performing sectors in early 1997 and, subsequently, as
rates began an uptrend in February. At that point, the management team reduced
duration to neutral and adopted a barbell strategy that sought to take advantage
of stronger relative values at the short and long ends of the yield curve. As
the reporting period ended, the Fund took profits on some of its mortgage-backed
securities but maintained a relatively-neutral sector allocation.
 
Moving forward, the management team expects economic growth in the U.S. to
moderate and, therefore, anticipates significant opportunities in both the stock
and bond markets.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES -- Mutual Fund Group ( the
"Trust") was organized on May 11, 1987 as a Massachusetts Business Trust, and is
registered under the Investment Company Act of 1940, as amended, (the "1940
Act") as an open-end management investment company. Vista Growth and Income Fund
("VGIF"), Vista Capital Growth Fund ("VCGF"), Vista Small Cap Equity Fund
("VSCEF"), Vista Equity Income Fund ("VEIF"), Vista Large Cap Equity Fund
("VLCEF") (formerly Vista Equity Fund), Vista American Value Fund ("VAVF") and
Vista Balanced Fund ("VBAL"), collectively, the "Funds", are seven separate
series of The Trust. The Funds offer various classes of shares as follows:
 
<TABLE>
<CAPTION>
 Fund                                          Classes Offered
- ------                  -------------------------------------------------------------
<S>                     <C>
VGIF                    Class A, Class B, Institutional
VCGF                    Class A, Class B, Institutional
VSCEF                   Class A, Class B, Institutional
VEIF                    Class A, Class B
VLCEF                   Class A, Class B, Institutional
VAVF                    Class A
VBAL                    Class A, Class B
</TABLE>
 
Class A shares, with the exception of VAVF, generally provide for a front-end
sales charge while Class B shares provide for a contingent deferred sales
charge. All classes of shares have equal rights as to earnings, assets and
voting privileges except that each class may bear different distribution fees
and each class has exclusive voting rights with respect to its distribution
plan. No sales charges are assessed with respect to the Institutional Class.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates.
 
The following is a summary of significant accounting policies followed by the
Funds:
 
    A.   VGIF and VCGF
 
    Effective November 29, 1993, VGIF and VCGF adopted the Master Feeder Fund
    structure through the contribution of their investment assets to their
    respective portfolios in exchange for beneficial interests in such
    portfolios of an equal value. Prior thereto each Fund owned individual
    investment securities. VGIF and VCGF seek to achieve their investment
    objective by investing all of their investable assets in the Growth and
    Income Portfolio and the Capital Growth Portfolio respectively (the
    "Portfolios") which like the Funds, are open-end management investment
    companies having the same investment objectives as the Funds. As of April
    30, 1997 VGIF and VCGF owned 94.82% and 99.99% of the Growth and Income
    Portfolio, and of the Capital Growth Portfolio, respectively. The financial
    statements of each Portfolio, including the portfolio of investments, are
    included elsewhere in this report and should be read in conjunction with the
    financial statements of the Funds.
 
       1.   Valuation of investments -- VGIF and VCGF record their investments
       in their respective Portfolios at value. Securities of the Portfolios are
       recorded at value as more fully discussed in the notes to those financial
       statements.
 
       2.   Investment income and expenses -- VGIF and VCGF record daily their
       pro-rata share of the respective Portfolio's income, expenses, and
       realized and unrealized gains and losses. In addition, the Funds accrue
       their own expenses daily as incurred. Realized gains/losses and changes
       in unrealized appreciation/depreciation represent the Fund's share of
       such elements allocated from the portfolio.
 
    B.   VSCEF, VEIF, VLCEF, VAVF and VBAL
 
       1.   Valuation of investments -- Equity securities, purchased options and
       futures are valued at the last sale price on the exchange on which they
       are primarily traded, including the NASDAQ National Market. Securities
       for which sale prices are not available and other over-the-counter
       securities are valued at the last quoted bid price. Bonds and other fixed
       income securities (other than short-term obligations), including listed
       issues, are valued on the basis of valuations supplied by pricing

       services or by matrix pricing systems of a major dealer in bonds.
       Short-term debt securities with 61 days or more to maturity at time of
       purchase are valued, through the 61st day prior to maturity, at market
       value based on quotations obtained from market makers or other
       appropriate sources; thereafter, the value on the 61st day is amortized
       on a straight-line basis over the remaining number of days to maturity.
       Short-term investments with 60 days or less to maturity at time of
       purchase are valued at amortized cost, which approximates market.
       Portfolio securities for which there are no such quotations or valuations
       are valued at fair value as determined in good faith by or at the
       direction of the Trustees.
 
       2.   Repurchase agreements -- It is the Trust's policy that repurchase
       agreements are fully collateralized by U.S. Treasury and Government
       Agency securities. All collateral is held by the Trust's custodian bank,
       subcustodian, or a bank with which the custodian bank has entered into a
       subcustodian agreement, or is segregated in the Federal Reserve Book
       Entry System. In connection with transactions in repurchase agreements,
       if the seller defaults and the value of the collateral declines, or if
       the seller enters an insolvency proceeding, realization of the collateral
       by the Trust may be delayed or limited.
 
       3.   Futures contracts -- When a Fund enters into a futures contract, it
       makes an initial margin deposit in a segregated account, either in cash
       or liquid securities. Thereafter, the futures contract is marked to
       market and the fund makes (or receives) additional cash payments daily to
       the broker. Changes in the value of the contract are recorded as
       unrealized appreciation/depreciation until the contract is closed or
       settled.
 
       The Funds invest in stock index futures contracts for the purpose of
       hedging the Fund against share price volatility, which purpose may or may
       not be achieved. When the Fund is not fully invested in the securities
       market, it may enter into "long" positions in futures or options
       contracts in order to gain rapid market exposure that may in part or
       entirely offset increases in the cost of securities intended for
       purchase. Use of futures contracts subject the Fund to risk of loss in
       excess of amounts shown on the Statement of Assets and Liabilities, up to
       the amount of the value of the futures contracts as shown in the
       Portfolio of Investments at April 30, 1997.
 
       The Fund may enter into futures contracts only on exchanges or boards of
       trade. The exchange or board of trade acts as the counterparty to each
       futures transaction, therefore, the Fund's credit risk is limited to
       failure of the exchange or board of trade.
 
       4.   Written options -- When a Fund writes an option on a futures
       contract, an amount equal to the premium received by the Fund is included
       in the Fund's Statement of Assets and Liabilities as an asset and
       corresponding liability. The amount of the liability is adjusted daily to
       reflect the current market value of the written options and the change is
       recorded in a corresponding unrealized gain or loss account. When a
       written option expires on its stipulated expiration date, or when a
       closing transaction is entered into, the related liability is
       extinguished and the Fund realizes a gain (or loss if the cost of the
       closing transaction exceeds the premium received when the option was
       written).
 
       The VSCEF writes options on stock index securities futures. These options
       are settled for cash and subject the Fund to market risk in excess of the
       amounts that are reflected in the Statement of Assets and Liabilities.
       The Fund, however, is not subject to credit risk on written options as
       the counterparty has already performed its obligation by paying a premium
       at the inception of the contract.
 
       As of April 30, 1997 the Funds had no outstanding written options.
 
       5.   Security transactions and investment income -- Investment
       transactions are accounted for on the trade date (the date the order to
       buy or sell is executed). Securities gains and losses are calculated on
       the identified cost basis. Interest income is accrued as earned. Dividend
       income is recorded on the ex-dividend date.
 
       6.   Dollar Rolls -- VBAL enters into dollar rolls in which the Fund
       sells mortgage-backed securities for delivery in the current month and
       simultaneously contracts to repurchase substantially similar (same type,
       coupon and maturity) securities on a specified future date. During the
       roll period, the Fund forgoes principal and interest paid on the
       securities. The Fund is compensated by the interest earned on the cash
 
                                       53

       proceeds of the initial sale and a fee earned for entering into the roll
       transaction. The fee is amortized into income over the duration of the
       roll transaction.
 
    C.   General Policies
 
       1.   Organization costs -- Organization and initial registration costs
       incurred in connection with establishing the Funds have been deferred and
       are being amortized on a straight-line basis over a sixty month period
       beginning at the commencement of operations of each Fund.
 
       2.   Federal income taxes -- Each Fund is treated as a separate taxable
       entity for Federal income tax purposes. The Trust's policy is to comply
       with the provisions of the Internal Revenue Code applicable to regulated
       investment companies and to distribute to shareholders all of its
       distributable net investment income, and net realized gain on
       investments. In addition, the Trust intends to make distributions as
       required to avoid excise taxes. Accordingly, no provision for Federal
       income or excise tax is necessary.
 
       3.   Distributions to shareholders -- Dividends and distributions paid to
       shareholders are recorded on the ex-dividend date. The amount of
       dividends and distributions from net investment income and net realized
       capital gains is determined in accordance with Federal income tax
       regulations, which may differ from generally accepted accounting
       principles. To the extent these "book/tax" differences are permanent in
       nature, (i.e., that they result from other than timing of
       recognition -- "temporary differences") such amounts are reclassified
       within the capital accounts based on their Federal tax-basis treatment.
       The adjustments for the Funds relate primarily to the character for tax
       purposes of certain short-term gains or losses. Dividends and
       distributions which exceed net investment income or net realized capital
       gains for financial reporting purposes but not for tax purposes are
       reported as distributions in excess of net investment income or net
       realized capital gains.
 
       4.   Expenses -- Expenses directly attributable to a Fund are charged to
       that Fund; other expenses are allocated proportionately among each Fund
       within the Trust in relation to the net assets of each Fund or on another
       reasonable basis. In calculating the net asset value per share of each
       class, investment income, realized and unrealized gains and losses and
       expenses other than class specific expenses, are allocated daily to each
       class of shares based upon the proportion of net assets of each class at
       the beginning of each day.
 
2.   FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
    A.   Investment advisory fee -- Pursuant to separate Investment Advisory
    Agreements, The Chase Manhattan Bank, ("Chase" or the "Adviser") acts as the
    Investment Adviser to the VSCEF, VEIF, VLCEF, VAVF, and VBAL. Chase is a
    direct wholly-owned subsidiary of The Chase Manhattan Corporation. As
    Investment Adviser, Chase supervises the investments of the Funds and for
    such services is paid a fee. The fee is computed daily and paid monthly at
    an annual rate equal to 0.50% for VBAL, 0.65% for VSCEF and 0.40% for VEIF
    and for VLCEF; and 0.70% for VAVF of the average daily net assets. The
    Adviser, voluntarily waived all or a portion of its fees as outlined in Note
    2.E. below.
 
    Chase Asset Management, Inc. ("CAM"), a registered investment adviser, is
    the sub-investment adviser to each Fund, with the exception of VAVF,
    pursuant to a Sub-Investment Advisory Agreement between CAM and Chase. CAM
    is a wholly owned subsidiary of Chase and is entitled to receive a fee,
    payable by Chase from its advisory fee, at an annual rate equal to 0.20% of
    VEIF and VLCEF; 0.25% of VBAL; and 0.30% of VSCEF's of average daily net
    assets.
 
    VanDeventer and Hoch, a registered investment adviser is the sub-investment
    advisor for VAVF pursuant to a Sub-Investment Advisory Agreement with Chase
    and is paid a fee by Chase at an annual rate equal to 0.35% of the VAVF's
    average daily net assets.
 
    B.   Shareholder servicing fees -- The Trust has adopted an Administrative
    Services Plan which, among other things, provides that the Trust on behalf
    of the Funds may obtain the services of one or more Shareholder Servicing
    Agents. For its services, the Shareholder Servicing Agents receive a fee
    that is computed daily and paid monthly at an annual rate equal to 0.25% of
    the average daily net assets of each of the classes of the funds with the
 
                                       54

    exception of the Class A Shares of the VSCEF. The VSCEF is charged a fee
    from non-affiliated shareholder serving agents not to exceed 0.25% of the
    net assets of the Class. For the six months ended April 30, 1997, Chase's
    Shareholder Servicing charges amounted to: VGIF: $2,629,007, VCGF:
    $1,364,080, VSCEF: $273,578, VEIF: $2,590, VLCEF: $134,493, VAVF: $0, and
    VBAL: $12,584.
 
    The Shareholder Servicing Agents have voluntarily waived all or a portion of
    their fees as outlined in Note 2.E. below.
 
    C.   Distribution and sub-administration fees -- Pursuant to a Distribution
    and Sub-Administration Agreement, Vista Fund Distributors, Inc. (the
    "Distributor"), a wholly owned subsidiary of The BISYS Group, Inc., acts as
    the Trust's exclusive underwriter and promotes and arranges for the sale of
    each Fund's shares. In addition, the Distributor provides certain
    sub-administration services to the Trust, including providing officers,
    clerical staff and office space for an annual fee of 0.05% of the average
    daily net assets of each Fund.
 
    The Trustees have adopted Distribution Plans (the "Distribution Plans") for
    Class A and B (with the exception of VAVF) for the VGIF, VCGF, VSCEF, VEIF,
    VLCEF, VAVF, and VBAL in accordance with Rule 12b-1 under the 1940 Act.
    There is no Distribution Plan for the Institutional Classes. The Class A
    Distribution Plans provide that each Fund shall pay distribution fees,
    including payments to the Distributor, at annual rates not to exceed 0.25%
    of the average daily net assets of the Class A Shares of each Fund with the
    exception of VGIF and VCGF which pay 0.20% for distribution services. The
    Class B Distribution Plan provides that each Fund shall pay distribution
    fees, including payments to the Distributor, at an annual rate not to exceed
    0.75% of the average annual net assets of the Class B Shares for
    distribution services.
 
    Under Class A Distribution Plans for VGIF and VCGF, the Class A shares are
    also permitted to pay an additional fee at an annual rate not to exceed
    0.05% of its average daily net assets in anticipation of, or as
    reimbursement for, expenses incurred in connection with print or electronic
    media advertising in connection with the sale of Fund shares. The maximum
    compensation paid by the Class A shares under the Class A Distribution Plan
    would be at an annual rate of 0.25% of its average daily net assets.
 
    The Distributor voluntarily waived all or a portion of distribution fees and
    sub-administration fees as outlined in Note 2.E. below.
 
    D.   Administration fee -- Pursuant to an Administration Agreement, Chase
    (the "Administrator") provides certain administration services to the Trust.

    VEIF, VAVF, VBAL and VLCEF a fee computed at the annual rate equal to 0.10%
    of the respective Fund's average daily net assets and from VGIF and VCGF, a
    fee computed at the annual rate equal to 0.05% of the respective Fund's
    average daily net assets. The Administrator voluntarily waived all or a
    portion of the administration fees as outlined in Note 2.E. below.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES -- Growth and Income
Portfolio ("GIP") and Capital Growth Portfolio ("CGP"), (the "Portfolios") are
separately registered under the Investment Company Act of 1940, as amended, as
non-diversified, open end management investment companies organized as trusts
under the laws of the State of New York. Each declaration of trust permits the
Trustees to issue beneficial interests in the respective Portfolios. The GIP and
the CGP commenced operations on November 29, 1993.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that

results could differ from those estimates.
 
    The following is a summary of significant accounting policies followed by
    the Portfolios:
 
    A.   Valuation of investments -- Equity securities, purchased options and
    futures are valued at the last sale price on the exchange on which they are
    primarily traded, including the NASDAQ National Market. Securities for which
    sale prices are not available and other over-the-counter securities are
    valued at the last quoted bid price. Bonds and other fixed income securities
    (other than short-term obligations), including listed issues, are valued on
    the basis of valuations supplied by pricing services or by matrix pricing
    systems of a major dealer in bonds. Short-term debt securities with 61 days
    or more to maturity at time of purchase are valued, through the 61st day
    prior to maturity, at market value based on quotations obtained from market
    makers or other appropriate sources; thereafter, the value on the 61st day
    is amortized on a straight-line basis over the remaining number of days to
    maturity. Short-term investments with 60 days or less to maturity at time of
    purchase are valued at amortized cost, which approximates market. Portfolio
    securities for which there are no such quotations or valuations are valued
    at fair value as determined in good faith by or at the direction of the
    Trustees.
 
    B.   Repurchase agreements -- It is the Portfolios' policy that repurchase
    agreements are fully collateralized by U.S. Treasury and Government Agency
    securities. All collateral is held by the Trusts' custodian bank,
    subcustodian, or a bank with which the custodian bank has entered into a
    subcustodian agreement, or is segregated in the Federal Reserve Book Entry
    System. In connection with transactions in repurchase agreements, if the
    seller defaults and the value of the collateral declines, or if the seller
    enters an insolvency proceeding, realization of the collateral by the Trusts
    may be delayed or limited.
 
    C.   Futures contracts -- When a Portfolio enters into a futures contract,
    it makes an initial margin deposit in a segregated account, either in cash
    or liquid securities. Thereafter, the futures contract is marked to market
    and the portfolio makes (or receives) additional cash payments daily to the
    broker. Changes in the value of the contract are recorded as unrealized
    appreciation/depreciation until the contract is closed or settled.
 
    The GIP invested a portion of its liquid assets in long stock index futures
    contracts to more fully participate in the market. Use of futures contracts
    subject the Portfolio to risk of loss up to the amount of the value of the
    contract.
 
    The Portfolio may enter into futures contracts only on exchanges or boards
    of trade. The exchange or board of trade acts as the counterparty to each
    futures transaction, therefore, the Portfolio's credit risk is limited to
    failure of the exchange or board of trade.
 
    As of April 30, 1997, the Portfolios had no outstanding futures contracts.
 
    D.   Written options -- When a Portfolio writes an option on a futures
    contract, an amount equal to the premium received by the Portfolio is
    included in the portfolio's Statement of Assets and Liabilities as an asset
    and corresponding liability. The amount of the liability is adjusted daily
    to reflect the current market value of the written options and the change is
    recorded in a corresponding unrealized gain or loss account. When a written
    option expires on its stipulated expiration date, or when a closing
    transaction is entered into, the related liability is extinguished and the
    Portfolio realizes a gain (or loss if the cost of the closing transaction
    exceeds the premium received when the option was written).

    The GIP writes options on stock index securities futures. These options are
    settled for cash and subject the Portfolio to market risk in excess of the
    amounts that are reflected in the Statement of Assets and Liabilities. The
    Portfolio, however, is not subject to credit risk on written options as the
    counterparty has already performed its obligation by paying a premium at the
    inception of the contract.
 
    As of April 30, 1997 the Portfolios had no outstanding written options.
 
    E.   Security transactions and investment income -- Investment transactions
    are accounted for on the trade date (the date the order to buy or sell is
    executed). Securities gains and losses are calculated on the identified cost
    basis. Interest income is accrued as earned. Dividend income is recorded on
    the ex-dividend date.
 
    F.   Organization costs -- Organization and initial registration costs
    incurred in connection with establishing the Portfolios have been deferred
    and are being amortized on a straight-line basis over a sixty month period
    beginning at the commencement of operations of each Portfolio.
 
    G.   Federal income taxes -- The Portfolios intend to continue to qualify as
    partnerships and therefore net income and net realized gains are taxed to
    the partners. Accordingly, no tax provisions are recorded by the Portfolios.
    The investors in the Portfolios must take into account their proportionate
    share of the Portfolios' income, gains, losses, deductions, credits and tax
    preference items in computing their federal income tax liability, without
    regard to whether they have received any cash distributions from the
    Portfolio. The Portfolios do not intend to distribute to investors their net
    investment income or their net realized gains, if any. It is intended that
    the Portfolios will be managed in such a way that investors in the portfolio
    will be able to satisfy the requirements of subchapter M of the Internal
    Revenue Code to be taxed as regulated investment companies.
 
2.   FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
    A.   Investment advisory fee -- Pursuant to separate Investment Advisory
    Agreements, The Chase Manhattan Bank ("Chase" or the "Adviser") acts as the

    Chase Asset Management, Inc. ("CAM"), a registered investment adviser, is
    the sub-investment adviser to each of the Portfolios pursuant to a
    Sub-Investment Advisory Agreement between CAM and Chase. CAM is a wholly
    owned subsidiary of Chase and is entitled to receive a fee, payable by Chase
    from its advisory fee, at an annual rate equal to 0.20% of each Portfolio's
    average daily net assets.
 
    B.   Custodial fees -- Chase, as Custodian provides safekeeping services for
    the Portfolios' securities. Compensation for such services are presented in
    the Statement of Operations as custodian fees.
 
    C.   Administration fee -- Pursuant to an Administration Agreement, Chase
    (the "Administrator") provides certain administration services to the
    Trusts. For these services and facilities, the Administrator receives from
    each Portfolio a fee computed at the annual rate equal to 0.05% of the
    respective Portfolio's average daily net assets.
