As noted six months ago, we are in the process of redesigning your Shareholder
Reports to include even more information about your Fund, its current investment
strategy and how it is performing. In order to launch this new design at your
Fund's year-end, we are planning to introduce the new format with your next
Annual Report.
 
                                                                  April 10, 1997
 
Dear Shareholder:
 
We are pleased to present this semi-annual report for Vista Tax-Free Income
Fund, Vista New York Tax Free Income Fund and Vista California Intermediate Tax
Free Income Fund for the six months ended February 28, 1997. Inside, you'll find
information on the performance of each fund over the past six months along with
a market overview and portfolio commentary.
 
ECONOMIC GROWTH REPORTS CONTINUE TO DRIVE FIXED INCOME MARKETS
 
Over the six-month period, the yield on the 30-year U.S. Treasury bond declined
from 7.12% to 6.87% as fixed income markets continued to be driven by concerns
about the strength of the economy. In the fall, markets rallied strongly on
reports of a slowing economy. However, by mid-February, signs of a stronger
economy emerged and long-term rates began trending upward. As the reporting
period ended, most market participants expected the Federal Reserve Board to
raise the Federal Funds rate in a pre-emptive strike against potential
inflation.
 
MARKETS REACT TO IMPROVING STATE FINANCES & CONCERNS OVER WELFARE REFORM
 
Actions in Washington once again had a large impact on municipal bonds. Most
recently, the passage of Federal welfare reform has created concerns about the
ability of cities and counties with high welfare caseloads to meet their
obligations, especially in California and New York. When combined with improving
state finances, these concerns led many investors to favor state-appropriated
debt over that of cities and counties.
 
POSITIVE TOTAL RETURNS IN A VOLATILE ENVIRONMENT
 
Despite the volatile interest rate environment, each of the Vista Tax Free Funds
delivered a positive total return over the reporting period. This was due in
large part to the expertise and intensive work of our experienced team of
portfolio managers and analysts.
 
We appreciate the confidence you have placed in us and look forward to serving
your investment needs for many years to come. If you have any questions, please
call your investment professional or 1-800-34-VISTA.
 
Sincerely,

/s/ Fergus Reid
Fergus Reid
Chairman

Vista Tax Free Income Fund
 
Vista Tax Free Income Fund, which seeks to provide tax-exempt income through a
portfolio of higher-quality municipal bonds of varying maturities, finished the
six months ended February 28, 1997 with a total return of 5.53% (Class A,
without sales charge). This positive performance was achieved during a period of
rapidly-changing interest rate expectations.
 
INTEREST RATES FALL, THEN RISE
 
The six months began with interest rates falling in response to reports of an
economic slowdown. At that time, a slightly-long duration helped the Fund
participate in the market rally. As 1996 ended, however, the Fund's management
team began shortening duration with the expectation that economic growth would
accelerate. This stance proved to be correct.
 
While making slight adjustments to the portfolio in response to economic growth,
the management team's main emphasis remained on analyzing and finding value in
specific securities. In late 1996, for example, the management team sold off
holdings in the bonds of high-cost electric power providers based on credit
concerns. This move later proved beneficial for shareholders, as many of these
securities were downgraded by the ratings agencies.
 
FUND FAVORS STATE DEBT
 
Two main factors led the management team to generally shift assets from city and
county bonds to state-appropriated debt. The first was an ongoing concern over
the effect welfare reform would have on the finances of cities and counties,
particularly in areas with high welfare rolls such as California and New York.
Additionally, states continued to benefit from higher-than-expected tax revenues
thanks to the expanding national economy, leading several states to receive
upgrades from the ratings agencies.
 
As the reporting period ended, the Fund's portfolio continued to reflect the
management team's cautious stance with regard to interest rates and was slightly
underweight in New York on a tactical basis due to a tremendous amount of new
supply of state debt. Moving forward, the management team will continue to apply
in-depth research in search of high-quality securities that the team believes
may provide the most value for shareholders.

Vista New York Tax Free Income Fund
 
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,
finished the six months ended February 28, 1997 with a total return of 4.99%
(Class A, without sales charge). This positive performance was achieved during a
period of significant new supply in the market and rapidly-changing interest
rate expectations.
 
SCARCITY OF NEW ISSUES ENDS
 
Supply and demand factors, always important in the muni bond market, played a
major role in the investment management team's decision-making. Throughout the
reporting period, there was significant new supply of New York issues, causing
the state's bonds to underperform the general municipal market.
 
Several positive trends, however, offset the negative impact of this supply.
These included strong demand from property and casualty insurance companies,
increased retail investor interest and improving state finances. The management
team took advantage of the new supply to upgrade the overall credit quality of
the portfolio with emphasis on water and sewer bonds as well as
state-appropriated debt.
 
MANAGEMENT TEAM ANTICIPATES HIGHER INTEREST RATES
 
The six months began with interest rates falling in response to reports of an
economic slowdown. At this time, a slightly-long duration helped the Fund
participate in the market rally. As 1996 ended, however, the Fund's management
team began shortening duration with the expectation that economic growth would
accelerate.
 
Moving forward, there is a possibility that New York state general obligation
debt will be upgraded by the ratings agencies. Therefore, as the quarter ended,
the management team was actively searching for issues which would potentially
benefit from improving credit quality trends in a supply-rich market.

Vista California Intermediate Tax Free Income Fund
 
As the California economy continued to improve, Vista California Intermediate
Tax Free Income Fund finished the six months ended February 28, 1997 with a
total return of 4.38% (Class A, without sales charge). The Fund seeks to provide
double tax-exempt income through a portfolio of higher-quality,
intermediate-term municipal bonds.
 
WELFARE REFORM CONCERNS LEAD TO FOCUS ON STATE DEBT
 
Throughout the reporting period, the management team favored state-issued bonds
as well as those of essential-service revenue sectors over the general
obligation debt of cities and counties. The main reason for this bias was
ongoing concern over the potential effects of welfare reform on municipalities
given California's high welfare demands and number of immigrants.
 
Supply of new issues during the reporting period was thin, and the major
activity in the portfolio involved repositioning among sectors. Specifically,
the management team sold the bonds of high-cost electric power providers due to
credit concerns. This move helped performance, as many of these securities were
later downgraded by the ratings agencies. Additionally, the Fund continued to
favor water and sewer bonds.
 
A FOCUS ON INDIVIDUAL SECURITIES IN AN UNCERTAIN INTEREST RATE ENVIRONMENT
 
Expecting that interest rates will be volatile in the months ahead, the
management team ended the reporting period in search of credits that tend to be
more stable, such as high-quality housing bonds. Moving forward, the management
team will continue to apply in-depth research in search of high-quality
securities it believes may provide the most value for shareholders.

future performance. Investment return and principal will fluctuate with market
conditions. When shares are redeemed, they may be worth more or less than their
original cost.
 
This chart illustrates comparative performance for $10,000 invested in Class A
shares of the Vista California Intermediate Tax Free Income Fund, the unmanaged
Lehman Municipal Bond Index and the Lipper California Intermediate Funds Average
from July 15, 1993 to February 28, 1997. The Fund's performance includes a 4.50%
sales charge and assumes the reinvestment of all dividends and capital gains.
The performance of the average and the index does not include a sales charge and
has been adjusted to reflect reinvestment of all dividends and, for the Average,
capital gains.
 
A portion of the Fund's income may be subject to the Alternative Minimum Tax,
and some investors may be subject to certain state and local taxes.
 
The Fund is currently waiving fees. This voluntary waiver may be modified or
terminated at any time, which would reduce performance.
 
The Lehman Municipal Bond Index is a total return performance benchmark for the
long-term, investment grade tax-exempt bond market. Bonds included in the Lehman
Municipal Bond Index are representative of the market.
 
The Lipper California Intermediate Municipal Debt Funds Average represents the
average performance of a universe of 32 actively managed California tax-exempt
municipal bond funds. Lipper is an independent mutual fund performance monitor
whose results are based on total return and do not reflect a sales charge.

VISTA MUTUAL FUNDS
NOTES TO FINANCIAL STATEMENTS (unaudited)
- --------------------------------------------------------------------------------
 
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.
 
    As of February 28, 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
 
                                       20

    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
    $104,114 for TFI. The Shareholder Servicing Agents voluntarily waived all or
    a portion of their fees as outlined in Note 2.E. below.
 
    C.   Distribution and Sub-administration fees -- Pursuant to a Distribution
    and Sub-administration Agreement, Vista Fund Distributors, Inc. ("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.

August 31, 2003. During the fiscal year ended August 31, 1996, TFI, NYTFI and
CITF utilized capital loss carryovers of approximately $820,000, $185,000 and
$289,000, 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.

As noted six months ago, we are in the process of redesigning your Shareholder
Reports to include even more information about your Fund, its current investment
strategy and how it is performing. In order to launch this new design at your
Fund's year-end, we are planning to introduce the new format with your next
Annual Report.
 
                                                                  April 10, 1997
Dear Shareholder:
 
We are pleased to present this semi-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 such fund as of February 28, 1997 as well as listings of
current holdings.
 
MANAGING YOUR MONEY IN A CHANGING INTEREST RATE ENVIRONMENT
 
Over the six-month period, the yield on the one-year U.S. Treasury bill declined
from 5.89% to 5.67%. However, this rather benign overview masks a
highly-volatile environment dominated by changing perceptions of the strength of
U.S. economic growth as well as the market's anticipation of Federal Reserve
Board policy changes.
 
At the beginning of the period, reports of a slowing economy led many market
participants to believe that the Fed would not raise interest rates and, as a
result, the yield on the one-year T-bill fell to a low of 5.35% at the end of
November, 1996. The turning point in yields came in early December in response
to weaker demand and fears that the Fed might raise interest rates. The market
became inconsistent as investors reacted to each new report on the economy's
strength and attempted to determine the Fed's stance. By the time Fed Chairman
Greenspan testified before Congress in February, it was clear that he was set to
raise the Federal Funds rate to preempt any wage inflation.
 
SUPPLY & DEMAND FACTORS DOMINATE TAX FREE MONEY MARKETS
 
As usual, the yields available on the securities in your funds were
highly-dependent on supply and demand factors. Since many investors use tax-free
money market funds as a parking place for dollars they'll eventually use for
longer-term investments or to pay taxes, each fund's invested assets fluctuate
substantially. Additionally, there are traditional times of the year when
short-term tax free instruments mature, requiring that your fund re-invest at
prevailing interest rates. Together, these factors create a challenging job for
Vista's tax-free money market management team -- one I'm pleased to note they

(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) No fees are being waived for the Premier Shares and Institutional Shares of
    Vista Tax Free Money Market Fund. All other yields reflect the voluntary
    waiver of certain expenses and the assumption of certain expenses otherwise
    payable by the Fund. This voluntary waiver may be modified or terminated at
    any time, which would reduce the funds' performance.
 
(3) A portion of the funds' income may be subject to the Alternative Minimum Tax
    (AMT), and some investors may be subject to certain state and local taxes.
 
(4) Taxable Equivalent Yields are calculated based on the SEC Yield divided by 1
    minus the effective tax rate. Effective combined federal, state and/or local
    tax rates for Tax Free Money Market, New York Tax Free Money Market and
    California Tax Free Money Market are 36%, 40.56% and 42.40%, respectively.

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>

                          Fund                                     Classes Offered
- --------------------------------------------------------    ------------------------------

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 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.

</TABLE>
 
    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, 1996, 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, $50,000 and
$16,000, respectively. Such losses will be available to offset future capital
gains and will expire between August 31, 2001 and 2004. During the fiscal year
ended August 31, 1996, NYTFMM and TPMM utilized capital loss carryovers of
approximately $12,000 and $85,000, respectively. 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

As noted six months ago, we are in the process of redesigning your Shareholder
Reports to include even more information about your Fund, its current investment
strategy and how it is performing. In order to launch this new design at your
Fund's year-end, we are planning to introduce the new format with your next
Annual Report.
 
                                                                  April 10, 1997
Dear Shareholder:
 
We are pleased to present this semi-annual report on each of the taxable Vista
money market funds. Inside, you'll find current seven-day yields for each fund
as of February 28, 1997 as well as current holdings.
 
MANAGING YOUR MONEY IN A CHANGING INTEREST RATE ENVIRONMENT
 
Over the six-month period, the yield on the one-year U.S. Treasury bill declined
from 5.89% to 5.67%. However, this rather benign overview masks a
highly-volatile environment dominated by changing perceptions of the strength of
U.S. economic growth as well as the market's anticipation of Federal Reserve
Board policy changes.
 
At the beginning of the period, reports of a slowing economy led many market
participants to believe that the Fed would not raise interest rates. As a
result, the yield on the one-year T-bill fell to a low of 5.35% at the end of
November, 1996. In early December, however, weaker demand and fears that the Fed
might raise interest rates created a turning point for yields. The market became
inconsistent as investors reacted to each new report on the economy's strength
and attempted to determine the Fed's stance. By the time Fed Chairman Greenspan
testified before Congress in February, it was clear that he was set to raise the
Federal Funds rate to pre-empt any wage inflation.
 
ANTICIPATING MORE VOLATILITY
 
The Fed did indeed raise the Federal Funds rate by .25% after the reporting
period ended. Given the strong economy and Mr. Greenspan's history of combining
several small rate increases over a period of months, our forecasts call for at
least one more Fed increase to slow economic growth later in 1997.
 
The Vista money market management team has stayed true to a certain course: to
seek stability, liquidity and attractive yields, prudently taking advantage of
opportunities while seeking to protect the principal value of your short-term
funds. We appreciate the confidence you have placed in us and encourage you to
call your investment professional or 1-800-34-VISTA if you have any questions.
 
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) No fees are being waived for the Premier Shares and Institutional Shares of
    Vista 100% U.S. Treasury Securities Money Market Fund, Vista Treasury Plus
    Money Market Fund and Vista Federal Money Market Fund. No fees are being
    waived for the Institutional Shares of Vista U.S. Government Money Market
    Fund, Vista Federal Money Market Fund, Vista Cash Management Fund and Vista
    Prime Money Market Fund; all other yields reflect the voluntary waiver of
    certain expenses and the assumption of certain expenses otherwise payable by
    the Fund. This voluntary waiver may be modified or terminated at any time,
    which would reduce the funds' performance.

** Commenced June 3, 1996.

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 February 28, 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.
 
    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 $1,009,785, $1,506,179,
    $846,392, $260,675, $372,348 and $176,946 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.
 
    C.   Distribution and sub-administration fees -- Pursuant to the
    Distribution and Sub-administration Agreements, Vista Fund Distributors,
    Inc. ("VFD" or the "Distributor"), a
 
                                       30

- --------------------------------------------------------------------------------
 
    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 -- 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, 1996, Prime Money Market Fund
had net capital loss carryovers of approximately $11,000. Such losses will be
available to offset future capital gains and will expire between August 31, 2001
and 2004. During the fiscal year ended August 31, 1996, NYTFMM utilized capital
loss carryovers of approximately $12,000. 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.
