                                   HIGHLIGHTS

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%.

                               CHAIRMAN'S LETTER

                                                                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.

</TABLE>

(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

    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.
 
6.  TRUSTEE COMPENSATION--The Funds have adopted an unfunded noncontributory
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
Trustees Fees and Expenses in the Statement of Operations, and accrued pension
liability included in other accrued liabilities, in the Statement of Assets and
Liabilities were as follows:

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

Changing perceptions of the strength of U.S. economic growth were the primary
drivers of short-term interest rates 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 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 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 yield would have been 4.93% for Vista Shares
   and 5.04% 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 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.

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:

 * 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.
 
3.  FEDERAL INCOME TAX MATTERS--During the fiscal year ended August 31, 1997,
PMM utilized capital loss carryovers of approximately $11,000.
 
                                                                              47

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 (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), 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. The selected per share data 
and ratios for a share of beneficial interest outstanding of Vista Cash 
Management Fund and Vista 100% U.S. Treasury Securities Money Market Fund for 
each of the three years in the period ended November 30, 1995 were audited by 
other independent accountants whose report dated January 19, 1996 expressed an 
unqualified opinion on the selected per share data and ratios for a share of 
beneficial interest outstanding.
