                               CHAIRMAN'S LETTER

                                                                October 10, 1997

Dear Shareholder:

We are pleased to present this annual report for Vista Tax Free Income Fund,
Vista New York Tax Free Income Fund and Vista California Intermediate Tax Free
Fund for the year ended August 31, 1997. Inside, you'll find information on the
performance of each fund along with a report from the portfolio management
team.

EXCEPTIONAL U.S. ECONOMY CHALLENGES TRADITIONAL THINKING

During the reporting year, the U.S. economy painted a near-perfect picture, one
characterized by substantial economic growth, excellent corporate performance,
strong job creation and the absence of inflationary pressures. This combination
of factors challenged the traditional economic view that a growing economy and
low unemployment inevitably lead to inflation and higher interest rates. Over
the course of the year, the yield on the 30-year Treasury bond fell from 7.11%
to 6.61%.

Against this backdrop, bond investors were highly sensitive to each report on
the economy's performance. This created occasional periods of volatility as
they anticipated whether the strong growth would cause inflation to erupt.
Other factors in the municipal bond markets were the general lack of supply,
improving state and local finances and concerns that lower interest rates would
entice issuers to refund higher-yielding debt.

This environment proved challenging for Vista's tax free portfolio management
team, but I'm pleased to report that the management team fulfilled their
mission of providing you with competitive yields and relative stability over
the one year period. On behalf of the management team and everyone at Vista, I
thank you for the confidence you've placed in us. We look forward to serving
your investment needs for many years to come.

Sincerely,

/s/ FERGUS REID

Fergus Reid
Chairman

PERFORMANCE

Vista Tax Free Income Fund, which seeks to provide tax-exempt income through a
portfolio of higher-quality municipal bonds of varying maturities, had a total
return of 9.14% for the year ended August 31, 1997 (Class A shares, without
sales charge). This compares to a return of 8.83% for the Lipper General
Municipal Debt Funds Average and 9.24% for the unmanaged Lehman Municipal Bond
Index.

STRATEGY

With the positive economic background creating occasional periods of interest
rate volatility as market participants reacted to each new report on the
economy's strength, the management team focused its efforts on analyzing and
finding value in specific securities.  During the first half of the year,
states continued to benefit from higher-than-expected tax revenues thanks to
the expanding national economy. As a result, the Fund generally shifted assets
from city and county bonds to state-appropriated debt.

This trend towards better finances accelerated and expanded as 1997 progressed
and led the independent ratings agencies to upgrade the credit ratings of many
types of municipal bond issuers. These upgrades, along with low supply and high
demand, led to a narrowing of the yield differential between higher- and
lower-quality securities. In this environment, the management team felt there
was little yield incentive to take on the credit risk associated with
lower-quality, investment grade bonds and, therefore, upgraded the Fund's
overall credit quality.

OUTLOOK

As the reporting year ended, the management team was expecting a significant
new supply of municipal bonds. This could have the effect of raising municipal
bond yields and making the market more attractive to new investors. Another
major factor moving forward will be the heavy volume of pre-refunded bonds in
1998. With so many investors needing to re-invest the proceeds, the management
team expects a strong demand for new issues. Following the successful strategy
of the past year, the focus will remain on active management as the management
team seeks to add value through research and analysis of individual securities.

PERFORMANCE

Vista New York Tax Free Income Fund, which seeks to provide triple tax-exempt
income through a portfolio of higher-quality, longer term municipal bonds, had
a total return of 8.85% for the year ended August 31, 1997 (Class A shares,
without sales charge). This compares to a return of 10.12% for the Lipper New
York Tax Exempt Municipal Debt Funds Average and 9.24% for the unmanaged Lehman
Municipal Bond Index.

STRATEGY

Unlike most states in the country, New York municipal bond issuers introduced a
significant new supply into the market during the reporting year. This
supply-rich environment, combined with improving state and local finances, led
the management team to take a very active approach in analyzing and identifying
individual securities.

Early in the reporting year, the management team focused on state-appropriated
debt as well as water and sewer bonds. But as the year progressed, so did the
credit characteristics of many cities and towns in the state. With the
plentiful supply of attractively-priced new issues of both state and local
bonds, the management team took advantage of opportunities to increase yield.
While some of these bonds underperformed over the short term, the strategy
eventually proved beneficial as the market was able to digest the heavy supply.

OUTLOOK

As the reporting year ended, the management team was expecting a significant
new supply of municipal bonds. This could have the effect of raising municipal
bond yields and making the market more attractive to new investors. Another
major factor moving forward will be the heavy volume of pre-refunded bonds in
1998. With so many investors needing to re-invest the proceeds, the management
team expects continued strong demand for new issues. Following the successful
strategy of the past year, the focus will remain on active management as the
management team seeks to add value through research and analysis of individual
securities.

PERFORMANCE

Vista California Intermediate Tax Free Fund, which seeks to provide double
tax-exempt income through a portfolio of higher-quality, intermediate-term
municipal bonds, had a total return of 7.46% for the year ended August 31, 1997
(Class A shares, without sales charge). This compares to a return of 7.29% for
the Lipper California Intermediate Municipal Debt Funds Average and 9.74% for
the Lehman California Municipal Bond Index.

STRATEGY

The California economy continued to improve throughout the reporting year, as
did the scarce supply of new issues in the market. As a result, the portfolio
management team focused on analyzing and finding value in specific securities
and repositioning among sectors. In the first half of the fiscal year, the Fund
favored state-issued bonds and essential service revenue sectors over the
general obligation debt of cities and counties. The management team also sold
the bonds of high-cost electric power providers due to credit concerns.

As the reporting year progressed, the trend towards better finances accelerated
and expanded. This led the independent ratings agencies to upgrade the credit
rating of the State of California and other California issuers. These upgrades,
along with low supply and high demand, led to a narrowing of the yield
differential between higher- and lower-quality securities. In this environment,
the management team felt there was little yield incentive to take on the credit
risk associated with lower-quality bonds. Therefore, management sold bonds with
less desirable coupons or call provisions and bought better-structured and
higher-quality bonds without giving up much yield.

OUTLOOK

As the reporting year ended, the management team was expecting heavy volume of
pre-refunded bonds in 1998. With so many investors needing to re-invest the
proceeds, the management team expects continued strong demand for new issues.
Following the successful strategy of the past year, the focus will remain on
active management as the management team seeks to add value through research
and analysis of specific securities.

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS
 
1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES--Mutual Fund Trust (the
"Trust") was organized as a Massachusetts business trust, and is registered
under the Investment Company Act of 1940, as amended, as an open-end,
non-diversified management investment company. Vista Tax Free Income Fund
("TFI"), Vista New York Tax Free Income Fund ("NYTFI"), and Vista California
Intermediate Tax Free Fund ("CITF") (collectively the "Funds"), are three
separate portfolios of the Trust.
 
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 TFI and NYTFI Funds offer two classes of shares, referred to as Class A
Shares and Class B Shares. Class B Shares were first available on November 4,
1993. 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 expenses and each class has exclusive
voting rights with respect to its distribution plan.
 
The following is a summary of significant accounting policies followed by the
Funds:
 
    A.   Valuation of investments--Fixed income securities (other than
    short-term obligations), including listed issues, are valued using matrix
    pricing systems of a major dealer in bonds which take into account factors
    such as institutional-size trading in similar groups of securities, yield,
    quality, coupon rate, maturity, type of issue, trading characteristics and
    other market data, without exclusive reliance upon quoted exchange or
    over-the-counter prices. 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.
 
    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,
    sub-custodian or a bank with which the custodian bank has entered into a
    sub-custodian 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 into an insolvency proceeding, realization of the collateral by the
    Trust may be delayed or limited.
 
    C.   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 and accretion of discount.
 
    D.   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 U.S. Treasury futures contracts as a hedge against
    market volatility while maintaining a tax exempt income stream.

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS (continued)
 
    As of August 31, 1997, the Funds had no outstanding futures contracts.
 
    E.   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.
 
    F.   Distributions to shareholders--Dividends are distributed in the form of
    additional shares of the Fund or, at the election of the shareholder, in
    cash (subject to the policies of the Shareholder Servicing Agent) on the
    last business day of the month. The net investment income of each Fund is
    determined daily and (substantially all) is declared as a dividend to
    shareholders of record at the time of such declaration. 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 will 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.
 
    G.   Allocation of income and expenses--Expenses directly attributable to a
    Fund are charged to that Fund; expenses directly attributable to a
    particular class are charged directly to such class, 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
    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 "Advisor") acts as the
    investment adviser to the Funds. 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
    accrued daily and paid monthly at an annual rate equal to 0.30% of each
    Fund's 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, 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 0.15% of each Fund'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, each Shareholder Servicing Agent receives a fee.
    The fee is computed daily and paid monthly at an annual rate of 0.25% of the
    average daily net assets of each Fund.
 
    Except as described below, since inception of the Trust, Chase and certain
    affiliates have been the only Shareholder Servicing Agents. In 1996, certain
    Class A Shareholders of TFI entered into a Shareholder Servicing arrangement
    with Charles Schwab & Co. Chase's Shareholder Servicing charges amounted to
    $204,606 for TFI. The Shareholder Servicing Agents voluntarily waived all or
    a portion of their fees as outlined in Note 2.E. below.
 
                                                                              31

    C.   Distribution and Sub-administration fees--Pursuant to a Distribution
    and Sub-administration Agreement, Vista Fund Distributors, Inc. ("VFD" or
    the "Distributor"), a wholly-owned subsidiary of the BISYS Group Inc.
    (BISYS), 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 for all Funds and Class B for TFI and NYTFI in accordance with Rule
    12b-1 under the 1940 Act.
 
    The Distribution Plans provide that each Fund shall pay distribution fees at
    annual rates not to exceed 0.25% of each Fund's average daily net assets for
    Class A shares and 0.75% for Class B shares.
 
    The Distributor voluntarily waived all or a portion of distribution 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 at a
    fee computed at an annual rate equal to 0.10% of the respective Fund's
    average daily net assets. The Administrator voluntarily waived all or a
    portion of its administration fees as outlined in Note 2.E. below.
 
    E.   Waivers of fees--For the year ended August 31, 1997, the Adviser,
    Shareholder Servicing Agents, Distributor and Administrator voluntarily
    waived fees for each of the Funds as follows:

At August 31, 1997, Tax Free Income Fund had a net capital loss carryover of
approximately $2,031,000 which will be available through August 31, 2003 to
offset future capital gains to the extent provided by regulations. During the
fiscal year ended August 31, 1997, TFI and NYTFI utilized capital loss
carryovers of approximately $2,059,000 and $641,000, respectively. To the extent
that any net capital loss carryovers are used to offset future capital gains, it
is probable that the gains so offset will not be distributed to shareholders.

REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Trustees and Shareholders of
Mutual Fund Trust
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the selected per share data and ratios for a share of
beneficial interest outstanding present fairly, in all material respects, the
financial position of Vista Tax Free Income Fund, Vista New York Tax Free Income
Fund and Vista California Intermediate Tax Free Fund (separate portfolios of
Mutual Fund Trust, hereafter referred to as the "Trust") at August 31, 1997, the
results of each of their operations for the year then ended, the changes in each
of their net assets for each of the two years in the period then ended and the
selected per share data and ratios for a share of beneficial interest
outstanding for each of the periods presented, in conformity with generally
accepted accounting principles. These financial statements and selected per
share data and ratios for a share of beneficial interest outstanding (hereafter
referred to as "financial statements") are the responsibility of the Trust's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at August 31, 1997 by correspondence with the
custodian and the application of alternative auditing procedures where
securities purchased had not been received, provide a reasonable basis for the
opinion expressed above.

U.S. economic growth and supply and demand issues were the primary drivers of
the short-term tax-free market during the reporting year.

- - The Federal Reserve Board adjusted the Federal Funds rate only once, a 0.25%
  increase in March, 1997.

- - Over the course of the year, the yield on the one-year Treasury bill declined
  from 5.90% to 5.56%.

                                                                October 10, 1997

Dear Shareholder:

We are pleased to present this annual report on each of the Vista Tax-Free
Money Market Funds. Inside, you'll find current seven-day yields and taxable
equivalent yields for each fund as of August 29, 1997, as well as listings of
current holdings.

EXCEPTIONAL U.S. ECONOMY CHALLENGES TRADITIONAL THINKING

During the reporting year, the U.S. economy painted a near-perfect picture, one
characterized by substantial economic growth, excellent corporate performance,
strong job creation and the absence of inflationary pressures. This combination
of factors challenged the traditional economic view that a growing economy and
low unemployment inevitably lead to inflation and higher interest rates.

While bond markets remained highly sensitive to any signs of inflation
throughout the year-and the Federal Reserve Board raised the Federal Funds rate
in March as a preemptive strike-both inflation and interest rates were trending
downward as the reporting year ended. For tax-free money market funds, supply
and demand issues also proved challenging throughout the year as investors
continued to use the funds as a short-term home for assets ultimately intended
for taxes or long-term investments.

In this environment of fluctuating assets and changing perceptions of economic
growth, Vista's portfolio management team kept a strong focus on maintaining
your fund's stability, liquidity and attractive yield. On behalf of the
management team and everyone at Vista, I thank you for the confidence you've
placed in us. We look forward to serving your investment needs for many years
to come.

Sincerely,

/s/ FERGUS REID

(1) Past performance is not a guarantee of future results.  Yields will
    fluctuate.  An investment is neither insured nor guaranteed by the U.S.
    government and there can be no assurance that the funds will maintain a
    stable Net Asset Value of $1.00 per share.

(2) The yield for Vista Shares reflects the voluntary waiver of certain
    expenses and the assumption of certain expenses otherwise payable by the
    Fund. Without waivers, the yield would have been 2.85%. This voluntary
    waiver may be modified or terminated at any time, which would reduce
    performance.

(3) Taxable equivalent yields are calculated based on the SEC yield divided by
    1 minus the effective tax rate. The effective federal tax rate used for
    this illustration is 39.6%.

    A portion of the Fund's income may be subject to the Alternative Minimum
    Tax (AMT), and some investors may be subject to certain state and local
    taxes.

(1) Past performance is not a guarantee of future results.  Yields will
    fluctuate.  An investment is neither insured nor guaranteed by the U.S.
    government and there can be no assurance that the funds will maintain a
    stable Net Asset Value of $1.00 per share.

(2) The yield for Vista Shares reflects the voluntary waiver of certain
    expenses and the assumption of certain expenses otherwise payable by the
    Fund. Without waivers, the yield would have been 2.77%. This voluntary
    waiver may be modified or terminated at any time, which would reduce
    performance.

(3) Taxable Equivalent Yields are calculated based on the SEC yield divided by
    1 minus the effective tax rate. The effective combined federal, state and
    local tax rate used for this illustration is 46.6%.

    A portion of the Fund's income may be subject to the Alternative Minimum
    Tax (AMT), and some investors may be subject to certain state and local
    taxes.

(1) Past performance is not a guarantee of future results.  Yields will
    fluctuate.  An investment is neither insured nor guaranteed by the U.S.
    government and there can be no assurance that the funds will maintain a
    stable Net Asset Value of $1.00 per share.

(2) The yield for Vista Shares reflects the voluntary waiver of certain
    expenses and the assumption of certain expenses otherwise payable by the
    Fund. Without waivers, the yield would have been 2.56%. This voluntary
    waiver may be modified or terminated at any time, which would reduce
    performance.

(3) Taxable equivalent yields are calculated based on the SEC Yield divided by
    1 minus the effective tax rate. The effective combined federal, and state
    tax rate used in this illustration is 46.24%.

    A portion of the Fund's income may be subject to the Alternative Minimum
    Tax (AMT), and some investors may be subject to certain state and local
    taxes.

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES--Mutual Fund Trust ("MFT")
(the "Trust") is organized as a Massachusetts business trust, and registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), as an
open-end, management investment company. Vista Tax Free Money Market Fund
("TFMM"), Vista New York Tax Free Money Market Fund ("NYTFMM") and Vista
California Tax Free Money Market Fund ("CATFMM") are separate portfolios of MFT.
Collectively all of these funds are referred to as "Money Market Funds" or
individually as the "Fund".
 
The funds offer various classes of shares as follows:
 
<TABLE>
<CAPTION>
                    Fund                               Classes Offered
- --------------------------------------------    ------------------------------
<S>                                             <C>
TFMM........................................    Vista, Premier, Institutional
NYTFMM......................................    Vista
CATFMM......................................    Vista
</TABLE>
 
All classes of shares have equal rights as to earnings, assets and voting
privileges except that each class may bear different transfer agent,
distribution, shareholder servicing and fund servicing expenses, and each class
has exclusive voting rights with respect to its distribution plan and
shareholder servicing agreement.
 
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--Money market instruments are valued at
    amortized cost which approximates market value. The Trust's use of amortized
    cost is subject to the Trust's compliance with certain conditions as
    specified under Rule 2a-7 of the 1940 Act.
 
    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,
    sub-custodian or a bank in 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 into an insolvency proceeding, realization of the collateral by the
    Trust may be delayed or limited.
 
    C.   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 consists of coupon interest accrued less the
    amortization of any premiums on the investments of the Funds.
 
    D.   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 a Fund's distributable
    net income, including 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.
 
    E.   Distributions to shareholders--Each Fund declares and records a
    dividend of substantially all of its net investment income on each business
    day. Such dividends are paid or re-invested monthly in each respective
    Fund's shares on the payable dates. 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 income 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.
 
    F.   Income and expenses--Expenses directly attributable to a Fund are
    charged to that Fund; expenses directly attributable to a particular class
    are charged directly to such class. Other expenses are allocated
    proportionately among the Funds within the Trust in relation to the net
    assets of each Fund or on another reasonable basis. 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.
 
2.  FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
    A.   Investment advisory fee--Pursuant to separate Investment Advisory
    Agreements, The Chase Manhattan Bank, ("Chase" or "Advisor") acts as the
    investment adviser to the Funds. Chase is a direct wholly-owned subsidiary
    of The Chase Manhattan Corporation. As investment adviser, Chase supervises
    the investments of each Fund and for such services is paid a fee. The fee is
    accrued daily and paid monthly at an annual rate equal to 0.10% of the
    average daily net assets for each respective Fund. The Advisor 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, other than the Vista Tax Fee Money
    Market Fund, 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
    0.03% of each Fund's average daily net assets.
 
    Texas Commerce Bank, National Association ("TCB") is the sub-investment
    adviser to the Vista Tax Free Money Market Fund pursuant to a Sub-Investment
    Advisory Agreement between Chase and TCB. TCB 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 0.03% of the Fund's average daily
    net assets.
 
    B.   Shareholder and Fund servicing fees--The Trust adopted an
    Administrative Service 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, each Shareholder Servicing
    Agent receives a fee. The fee is computed daily and paid monthly at an
    annual rate of 0.35% and 0.25% of the average daily net assets of the Vista
    Class and Premier Class, respectively.
 
    No Fund Servicing fee was paid for the Institutional Shares.
 
    Since inception of the Trust, Chase and certain of its affiliates have been
    the only Shareholder Servicing Agents. 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 the Distribution
    and Sub-administration Agreements, Vista Fund Distributors, Inc. ("VFD" or
    the "Distributor"), a wholly-owned subsidiary of the BISYS Group, Inc.
    ("BISYS"), 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 plans of distribution under the 1940 Act for the
    Vista Shares (the "Vista Plan"). There are no distribution plans for the
    Premier or Institutional Shares. Vista Plan pays the Distributor a
    distribution fee. The fee is
 
                                                                              47

    computed daily and paid monthly at an annual rate of 0.10% of the average
    daily net assets of Vista Class of each Fund.
 
    D.   Administration fee--Pursuant to the Administration Agreements, Chase
    (the "Administrator") provides certain administration services and
    facilities to each Fund at a fee computed at the annual rate equal to 0.05%
    of the respective Fund's average daily net assets.
 
    E.   Waivers of fees--For the year ended August 31, 1997, the Advisor,
    Shareholder and Fund Servicing Agents voluntarily waived fees for each of
    the Funds as follows:

    F.   Other--Certain officers of the Trust are officers of VFD or of its
    parent corporation, BISYS.
 
    In addition, Chase provides portfolio accounting and custody services for
    the Funds. Such amounts are presented in the Statement of Operations as
    custodian fees.
 
3.  FEDERAL INCOME TAX MATTERS--At August 31, 1997, Tax Free Money Market Fund,
New York Tax Free Money Market Fund and California Tax Free Money Market Fund
had net capital loss carryovers of approximately $386,000, $35,000 and $15,000,
respectively. Such losses will be available to offset future capital gains and
will expire between August 31, 2001 and 2005. During the fiscal year ended
August 31, 1997, NYTFMM utilized capital loss carryovers of approximately
$15,000. To the extent that any net capital losses are used to offset future
capital gains, it is probable that the gains so offset will not be distributed
to shareholders.

5.  CONCENTRATION OF CREDIT RISK--TFMM, NYTFMM and CATFMM, invest substantially
all of their assets in a diversified portfolio of debt obligations issued by
states, territories and possessions of the United States and by the District of
Columbia, and by their political subdivisions and duly constituted authorities,
with NYTFMM primarily investing in issuers in the State of New York, and CATFMM
primarily investing in issuers in the State of California. As of August 31,
1997, TFMM invested approximately 17.6% of its assets in issuers in the state of
Texas. The issuers' abilities to meet their obligations may be affected by
economic or political developments in a specific state or region.

defined benefit pension plan covering all independent trustees of the Funds who
will have served as an independent trustee 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 year ended August 31, 1997, included in

REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Trustees and Shareholders of
Mutual Fund Trust
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the selected per share data and ratios for a share of
beneficial interest outstanding present fairly, in all material respects, the
financial position of Vista Tax Free Money Market Fund, Vista New York Tax Free
Money Market Fund and Vista California Tax Free Money Market Fund (separate
portfolios of Mutual Fund Trust, hereafter referred to as the "Trust") at August
31, 1997, the results of each of their operations for the year then ended, the
changes in each of their net assets for each of the two years in the period then
ended, and the selected per share data and ratios for a share of beneficial
interest outstanding for each of the periods presented, in conformity with
generally accepted accounting principles. These financial statements and
selected per share data and ratios for a share of beneficial interest
outstanding (hereafter referred to as "financial statements") are the
responsibility of the Trust's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at August 31, 1997 by
correspondence with the custodian and the application of alternative auditing
procedures where securities purchased had not been received, provide a
reasonable basis for the opinion expressed above.

                                   HIGHLIGHTS

increase in March, 1997.

- - Over the course of the year, the yield on the one-year Treasury bill declined

                               CHAIRMAN'S LETTER

                                                                October 10, 1997
Dear Shareholder:

We are pleased to present this annual report on each of the taxable Vista money
market funds. Inside, you'll find current seven-day yields for each fund as of
August 29, 1997 as well as listings of current holdings.

EXCEPTIONAL U.S. ECONOMY CHALLENGES TRADITIONAL THINKING

During the reporting year, the U.S. economy painted a near-perfect picture, one
characterized by substantial economic growth, excellent corporate performance,
strong job creation and the absence of inflationary pressures. This combination
of factors challenged the traditional economic view that a growing economy and
low unemployment inevitably lead to inflation and higher interest rates.

Against this backdrop, bond investors were highly sensitive to each report on
the economy's performance. This created occasional periods of volatility as
they anticipated whether the Federal Reserve Board would make a preemptive
strike against inflation.  Ultimately, the Fed acted only once, raising the
Federal Funds rate slightly in March and effectively driving the yield on the
one-year Treasury bill to its highest point of the year. Rates subsequently
fell, however, and continued on a generally-downward trend as it became clear
that the Fed would not act again without clear and sustainable signs of
inflation.

This environment proved challenging for Vista's portfolio management team, but
I'm pleased to report that they fulfilled their mission of providing you with
competitive yields and a high degree of safety and stability. On behalf of the
management team and everyone at Vista, I thank you for the confidence you've
placed in us. We look forward to serving your investment needs for many years
to come.

Sincerely,

/s/ FERGUS REID
Fergus Reid
Chairman

1 Past performance is not a guarantee of future results. Yields will fluctuate.
  An investment is neither insured nor guaranteed by the U.S. government and
  there can be no assurance that the funds will maintain a stable Net Asset
  Value of $1.00 per share.

2 The yields for Vista Shares and Premier Shares reflect the voluntary waiver
  of certain expenses and the assumption of certain expenses otherwise payable
  by the Fund. Without waivers, the yields for Vista Shares would have been
  4.78% and for Premier Shares 4.69%. This voluntary waiver may be modified or
  terminated at any time, which would reduce the funds' performance.

1  Past performance is not a guarantee of future results. Yields will
   fluctuate. An investment is neither insured nor guaranteed by the U.S.
   government and there can be no assurance that the funds will maintain a
   stable Net Asset Value of $1.00 per share.

2  The yield for Vista Shares reflects the voluntary waiver of certain expenses
   and the assumption of certain expenses otherwise payable by the Fund.
   Without waivers, the yield would have been 4.76%. This voluntary waiver may
   be modified or terminated at any time, which would reduce the fund's
   performance.

1 Past performance is not a guarantee of future results. Yields will fluctuate.
  An investment is neither insured nor guaranteed by the U.S. government and
  there can be no assurance that the funds will maintain a stable Net Asset
  Value of $1.00 per share.

2 The yields for Vista Shares and Premier Shares reflect the voluntary waiver
  of certain expenses and the assumption of certain expenses otherwise payable
  by the Fund. Without waivers, the yields for Vista Shares would have been
  4.82% and 5.12% for Premier Shares. This voluntary waiver may be modified or
  terminated at any time, which would reduce the funds' performance.

1 Past performance is not a guarantee of future results. Yields will fluctuate.
  An investment is neither insured nor guaranteed by the U.S. government and
  there can be no assurance that the funds will maintain a stable Net Asset
  Value of $1.00 per share.

2 The yields for Vista and Premier Shares reflect the voluntary waiver of
  certain expenses and the assumption of certain expenses otherwise payable by
  the Fund. Without waivers, the yields would have been 5.05% for Vista Shares
  and 5.18% for Premier Shares.  This voluntary waiver may be modified or
  terminated at any time, which would reduce the funds' performance.

1 Past performance is not a guarantee of future results. Yields will fluctuate.
  An investment is neither insured nor guaranteed by the U.S. government and
  there can be no assurance that the funds will maintain a stable Net Asset
  Value of $1.00 per share.

2 The yields for B Shares and Premier Shares reflect the voluntary waiver of
  certain expenses and the assumption of certain expenses otherwise payable by
  the Fund. Without waivers, the yields would have been 4.24% for B Shares and
  5.22% for Premier Shares. This voluntary waiver may be modified or terminated
  at any time, which would reduce the funds' performance.

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS
- ---------------------------------------------------------------------
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES--Mutual Fund Trust ("MFT")
(the "Trust") is organized as a Massachusetts business trust, and registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), as an
open-end, management investment company. Vista 100% U.S. Treasury Securities
Money Market Fund ("USTSMM"), Vista U.S. Government Money Market Fund ("USGMM"),
Vista Treasury Plus Money Market Fund ("TPMM"), Vista Federal Money Market Fund
("FMM"), Vista Cash Management Fund ("CMMM"), and Vista Prime Money Market Fund
("PMM") are separate portfolios of MFT. Collectively all of these funds are
referred to as "Money Market Funds" or individually as the "Fund".
 
The funds offer various classes of shares as follows:

</TABLE>
 
- ---------------
 * Commenced May 6, 1996.
** Commenced June 3, 1996.
 
All classes of shares have equal rights as to earnings, assets and voting
privileges except that each class may bear different transfer agent,
distribution, shareholder servicing and fund servicing expenses, and each class
has exclusive voting rights with respect to its distribution plan and
shareholder servicing agreement.
 
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--Money market instruments are valued at
    amortized cost which approximates market value. The Trust's use of amortized
    cost is subject to the Trust's compliance with certain conditions as
    specified under Rule 2a-7 of the 1940 Act.
 
    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,
    sub-custodian or a bank in 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 into an insolvency proceeding, realization of the collateral by the
    Trust may be delayed or limited. In the event the buyer of securities under
    a reverse repurchase agreement files for bankruptcy or becomes insolvent,
    the Trust's use of proceeds of the agreement may be restricted pending a
    determination by the other party, or its trustee or receiver, whether to
    enforce the Trust's obligation to repurchase the securities. The Trust's use
    of the proceeds of the reverse repurchase agreement may also effectively be
    restricted pending such decision.
 
    At August 31, 1997, there were no open reverse repurchase agreements.
 
    C.   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 consists of coupon interest accrued and amortization
    of premium and discount earned.
 
                                                                              45

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS (continued)
- ---------------------------------------------------------------------
 
    D.   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 a Fund's distributable
    net income, including 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.
 
    E.   Distributions to shareholders--Each Fund declares and records a
    dividend of substantially all of its net investment income on each business
    day. Such dividends are paid or re-invested monthly in each respective
    Fund's shares on the payable dates. 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 income
    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.
 
    F.   Income and expenses--Expenses directly attributable to a Fund are
    charged to that Fund; expenses directly attributable to a particular class
    are charged directly to such class. Other expenses are allocated
    proportionately among the Funds within the Trust in relation to the net
    assets of each Fund or on another reasonable basis. 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.
 
2.  FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
    A.   Investment advisory fee--Pursuant to separate Investment Advisory
    Agreements, The Chase Manhattan Bank, ("Chase" or "Advisor") acts as the
    investment adviser to the Funds. Chase is a direct wholly-owned subsidiary
    of The Chase Manhattan Corporation. As investment adviser, Chase supervises
    the investments of each Fund and for such services is paid a fee. The fee is
    accrued daily and paid monthly at an annual rate equal to 0.10% of the
    average daily net assets for each respective Fund.
 
    Chase Asset Management, Inc. ("CAM"), a registered investment adviser, is
    the sub-investment adviser to each Fund, other than the Vista Cash
    Management Fund, 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 0.03% of each Fund's average daily net assets.
 
    Texas Commerce Bank, National Association ("TCB") is the sub-investment
    adviser to the Vista Cash Management Fund pursuant to a Sub-Investment
    Advisory Agreement between Chase and TCB. TCB 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 0.03% of the Fund's average daily
    net assets.
 
    B.   Shareholder and Fund servicing fees--The Trust, on May 6, 1996, adopted
    new Administrative Service Plans which, among other things, provide that the
    Trust on behalf of the Funds may obtain the services of one or more
    Shareholder Servicing Agents. For its services, each Shareholder Servicing
    Agent receives a fee. The fee is computed daily and paid monthly at an
    annual rate of 0.35%, 0.25% and 0.25% of the average daily net assets of the
    Vista, Premier and B Shares Class of each Fund. The Shareholder Servicing
    Agents voluntarily waived fees in the amount of $2,264,209, $3,007,989,
    $1,664,171, $457,964, $660,012 and $357,329 for the USTSMM, USGMM, TPMM,
    FMM, CMMM and PMM respectively.
 
    No Fund Servicing fee was paid for the Institutional Shares.

- ---------------------------------------------------------------------
 
    Since inception of the Trust, (except as described below) Chase and certain
    of its affiliates have been the only Shareholder Servicing Agents. Certain
    Premier Shareholders of the CMMM and FMM entered into a Shareholder
    Servicing arrangement with Capital Network Services and Charles Schwab & Co.
 
    C.   Distribution and sub-administration fees--Pursuant to the Distribution
    and Sub-administration Agreements, Vista Fund Distributors, Inc. ("VFD" or
    the "Distributor"), a wholly-owned subsidiary of the BISYS Group, Inc.
    ("BISYS"), 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 plans of distribution under the 1940 Act for the
    Premier Shares of USGMM (the "Premier Plan"), for the Vista Shares (the
    "Vista Plan") except for CMMM, and for the B Shares of the PMM (the "B
    Plan"). There are no distribution plans for the Institutional Shares. The
    Premier, Vista and B Shares Plans pay the Distributor a distribution fee.
    The fee is computed daily and paid monthly at an annual rate of: 0.10% of
    the average daily net assets of the Vista Class of each Fund (except CMMM),
    0.10% of the average daily net assets of the USGMM Premier Class and 0.75%
    of the average daily net assets of the B Shares of PMM.
 
    D.   Administration fee--Pursuant to the Administration Agreements, Chase
    (the "Administrator") provides certain administration services and
    facilities to each Fund at a fee computed at the annual rate equal to 0.05%
    of the respective Fund's average daily net assets.
 
    E.   Other--The Distributor voluntarily reimbursed the Funds for certain
    expenses in the amount of $9,429, $34,563, $2,681 for the USTSMM, TPMM and
    PMM, respectively.
 
    Certain officers of the Trust are officers of VFD or of its parent
    corporation, BISYS.
 
    In addition, Chase provides portfolio accounting and custody services for
    the Funds. Such amounts are presented in the Statement of Operations as
    custodian fees.

REPORT OF INDEPENDENT ACCOUNTANTS
- ---------------------------------------------------------------------
 
To the Trustees and Shareholders of
Mutual Fund Trust
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the selected per share data and ratios for a share of
beneficial interest outstanding present fairly, in all material respects, the
financial position of Vista 100% U.S. Treasury Securities Money Market Fund,
Vista U.S. Government Money Market Fund, Vista Treasury Plus Money Market Fund,
Vista Federal Money Market Fund, Vista Cash Management Fund and Vista Prime
Money Market Fund (separate portfolios of Mutual Fund Trust, hereafter referred
to as the "Trust") at August 31, 1997, the results of each of their operations
for the year then ended, the changes in each of their net assets for each of the
two years in the period then ended (for the year ended August 31, 1997 and for
the period December 1, 1995 through August 31, 1996 for Vista Cash Management
Fund and Vista 100% U.S. Treasury Securities Money Market Fund), and the
selected per share data and ratios for a share of beneficial interest
outstanding for each of the periods presented, in conformity with generally
accepted accounting principles. These financial statements and selected per
share data and ratios for a share of beneficial interest outstanding (hereafter
referred to as "financial statements") are the responsibility of the Trust's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at August 31, 1997 by correspondence with the
custodian and the application of alternative auditing procedures where
securities purchased had not been received, provide a reasonable basis for the
opinion expressed above.
