                               SEPTEMBER 30, 2004

                                                               November 16, 2004

Dear Fellow Shareholder:

  The Merger Fund(R) showed a gain in fiscal 2004 but fell short of its rate-
of-return targets.  As previously reported, the Fund's NAV rose 2.0% in the 12
months ended September.  While merger activity continued to recover in the
period, an unusual number of failed, renegotiated, seriously delayed or
otherwise troubled transactions weighed on our performance.  Out of the 106 new
arbitrage investments that we made in fiscal 2004, 16, or about 15%, fell into
one of the above categories.  For perspective, during the prior fiscal year, we
experienced only one broken deal and few other takeovers that caused us anxious
moments.  Since it's likely that whatever got into the water supply to cause so
many troubled mergers this past year has been flushed out of the system by now,
we believe that our fiscal 2004 results were more of an aberration than a
predictor of things to come.  Fiscal 2005 is off to a good start, and we hope
that it will be a year in which The Merger Fund(R) handily meets its investment
objectives.

  As is customary in these annual reports, we have included a series of charts
which reflect the nature of the arbitrage opportunities in which the Fund has
recently invested.  Chart 1 shows that as of September 30, friendly transactions
represented slightly more than 95% of the dollar value of our equity holdings,
while unsolicited, or hostile, takeover attempts accounted for about 5%.  The
latter figure, which is up marginally from the prior year's level, indicates
that hostile deals continue to represent a relatively small percentage of M&A
activity.  Although there are numerous explanations for the scarcity of
unsolicited takeover attempts, the fundamental reality facing hostile bidders is
that the odds of success are low.  Most of the common takeover defenses, such as
poison pills and staggered boards, have withstood legal challenge, and a target
company remains free to "just say no," even when presented with a richly valued
offer that a majority of its shareholders would willingly accept.  And should
the target conclude that remaining independent is no longer an option, there is
still no guarantee that the original suitor will ultimately prevail; a competing
bid by a white knight may well carry the day.

  Oracle's long-running effort-17 months and counting-to acquire PeopleSoft
illustrates some of the critical factors that can determine the outcome of a
hostile bid.  To fend off its unwanted suitor, PeopleSoft augmented its standard
arsenal of takeover defenses with a novel "customer assurance program." Under
this plan, Oracle would be on the hook to PeopleSoft's customers for more than
$2 billion should it fail to support their existing software following a
takeover.  PeopleSoft also actively lobbied federal and state regulators to
block the deal on antitrust grounds, and the company's independence appeared
secure when the Department of Justice subsequently filed suit against the
transaction.  Instead of giving up, however, Oracle chose to take the DOJ to
court.  Following a trial on the merits of the government's antitrust case, a
federal judge ruled in favor of Oracle and allowed its offer to proceed.  Only a
highly committed acquirer would have challenged the DOJ, and Oracle, led by its
strong-willed CEO, Larry Ellison, has repeatedly demonstrated its willingness to
stay the course.  Oracle has also been helped by the fact that PeopleSoft's
business has deteriorated since the offer was launched-making it harder for
PeopleSoft to convince its shareholders that they would be better off if the
takeover failed-and by the apparent absence of other potential bidders that
could realize the same synergies.  But despite all of these advantages, the
battle is not yet over.  Absent a negotiated transaction, Oracle may have to
wait until next spring to gain control of PeopleSoft's board and complete the
takeover.  This ongoing saga is a cautionary tale for all but the most highly
motivated and well-positioned suitors contemplating a hostile transaction.

  Chart 2 shows that approximately 93% of the acquisitions in which the Fund
has recently invested are strategic in nature, meaning combinations that involve
a corporate buyer-typically operating in the same industry as the target-whose
objective in doing the transaction is to enhance shareholder value on a longer-
term basis.  The rest are financial deals, mostly going-private transactions in
which an investor group that includes the target's management uses large amounts
of borrowed money to buy out the public shareholders.  In most cases, the goal
in such highly leveraged deals is to pay down debt and then either sell or IPO
the company, ideally within a relatively short time frame of just a few years.
The Fund's 7% exposure to financial transactions at the end of September
compares with an absence of holdings in this category a year earlier.  What's
changedo  To begin with, the stringent recordkeeping and corporate governance
requirements of the Sarbanes-Oxley law, coupled with a more intrusive and less
forgiving regulatory environment, may be causing a growing number of executives
to conclude that the benefits of public ownership are overrated.  Stated another
way, a CEO who worries that he might be just a headline away from needing the
services of an outplacement specialist-or worse, an attorney-may be more
receptive to the idea of taking his company private.  Leveraged-buyout firms
also appear to be benefiting from the fact that many publicly traded companies,
under pressure from an investment community that favors growth stories, are no
longer content to operate-let alone buy-businesses that may generate steady cash
flow but which have limited growth prospects.  For an LBO player, however, even
a business that is clearly in decline can represent an attractive investment
opportunity if the company's cash flow can be milked for a sufficiently long
period of time.  It is not surprising, therefore, that some of this year's
largest financial deals have involved no-growth businesses such as video
rentals, movie theaters and bowling alleys.  Another factor behind the upturn in
LBO activity has been the ability of the leading players to attract massive
amounts of equity capital from institutional investors.  Thanks to the ready
availability of low-cost debt financing, these funds can be leveraged several
times over, in some cases giving buyout firms the firepower to outbid their
strategic competitors.  From a merger-arbitrage standpoint, we have always
favored strategic deals over LBOs on the assumption that the former are less
accident-prone.  Last year's experience did little to make us think otherwise.
Although 14 of the Fund's 16 troubled deals involved strategic buyers, the two
LBOs that ran into problems represented a relatively large percentage of the
financial transactions in which we invested.

  Chart 3 shows the type of consideration to be received by the selling
company's shareholders in transactions in which The Merger Fund(R) held
positions at the end of September.  This year's chart looks considerably
different from the one included in our 2003 annual report.  More specifically,
cash, not stock, now appears to be the preferred deal currency.  A year ago,
all-stock transactions represented about 33% of the dollar value of our equity
investments, while all-cash deals accounted for just 23%.  Now, however, all-
stock transactions are only 21% of the total, and the percentage of all-cash
deals has nearly doubled to 44%.  Looked at another way, Chart 3 shows that
mergers and takeovers involving at least some cash make up 70% of the Fund's
portfolio.  A year earlier, the comparable figure was 54%.  A number of factors
appear to account for this shift in deal consideration, including the reluctance
of many acquirers to issue new shares at what they still consider to be
unattractive price levels; the fact that takeovers are often more accretive to
the buyer's bottom line when done as all-cash deals; the upturn in going-private
transactions, in which the target's shareholders typically receive only cash;
and the preference of some sellers for cash deals, whose value is unaffected by
the vagaries of the stock market.  As arbitrageurs, it matters little to us
whether we are to receive cash or stock; other issues are given much greater
weight in deciding whether to invest in any given corporate reorganization.
Nonetheless, deal terms do affect the Fund's hedging strategies.  When investing
in stock-for-stock mergers with fixed exchange ratios, we typically attempt to
lock in the arbitrage spread by selling short the acquirer's shares at the same
time that a long position is established in the target.  In this way, the Fund
is hedged against a decline in the acquirer's stock price prior to the close of
the transaction.  The use of such hedging strategies helps explain why the
performance of The Merger Fund(R) is largely uncorrelated with moves in the
market averages.

  Chart 4 shows our investments grouped by economic sector.  Again this year,
the Fund's holdings are well diversified, with no sector accounting for more
than 18% of the portfolio.  Healthcare, which at the end of fiscal 2003
represented our third-largest exposure, has moved to first place, while
telecommunications has jumped from seventh place to second.  Rounding out the
top three is financial services, the sector that over the years has provided us
with the largest number of arbitrage opportunities.  In the same way that the
type of consideration to be received is not high on our list of criteria for
selecting the Fund's investments, the economic sector in which the target
company operates is typically a secondary factor in our decision-making process.
More important to us, among other things, are the strategic rationale for the
transaction, the degree to which the parties are committed to bringing the
process to a close, the way in which the merger agreement is written, antitrust
and other regulatory issues and the buyer's deal-making history.

  Chart 5 shows the Fund's arbitrage investments grouped by the geographic
region in which the target company is domiciled.  At the end of fiscal 2003, 91%
of the deals in our portfolio involved U.S.-based targets, while another 4%
involved acquisitions of Canadian companies.  Although European transactions
totaled less than 4% of our investments as of September, earlier in the fiscal
year such deals accounted for a significantly larger percentage of the Fund's
holdings.  The Merger Fund(R) has the resources and expertise to invest
globally, and we routinely look at non-U.S. transactions as part of our effort
to identify compelling arbitrage opportunities.  It is true that investing
overseas often requires us to deal with a different set of political, governance
and regulatory issues, but we are careful not to get involved in a foreign
transaction unless we have done our homework and understand how the game is
played.  We also regularly hedge the currency risk in cross-border deals, so
that fluctuations in exchange rates rarely have a material impact on our
returns.

  Chart 6 shows the total dollar value of mergers and acquisitions in the U.S.,
by quarter, since 1991.  M&A activity, which peaked at an annual rate of $1.4-
$1.5 trillion in each of the years 1998, 1999 and 2000, bottomed at about $250
billion in 2002.  Calendar 2003 saw deal volume rebound 33%, and the recovery is
accelerating this year, with merger activity running at more than double 2003
levels.  Following a period in which many corporate executives were focused on
internal issues and wary of the economic and geopolitical outlook, confidence
appears to be returning to the boardroom.  And with it comes a greater
willingness to think strategically, a process that often includes a review of
potential corporate reorganizations.  Another constraint on deal-making over the
past several years has been the failure of many earlier transactions to deliver
the promised benefits to shareholders.  Against this background, Wall Street has
shown a tendency to penalize companies undertaking high-profile acquisitions,
especially if the deal is viewed as transformational in nature.  It comes as
good news, therefore, that a number of recently announced mergers and takeovers
have been well received by investors.  The more deals that generate positive
feedback, the easier it is for would-be acquirers to pull the trigger.  Overall,
we expect that M&A activity will continue to strengthen in the months ahead.

  In many respects, fiscal 2004 was an eventful year for The Merger Fund(R).
The Fund's investment adviser agreed to reduce its management fees, Morningstar
awarded us its highest grade for fund governance, our net assets reached an all-
time high and we closed the Fund to new investors.  As The Merger Fund(R)
approaches its 16th anniversary, we thank our shareholders for their continued
support and encouragement.  May the Fund's best years be yet to come!

The Merger Fund            1.99%         1.49%         5.30%        8.02%

The Standard & Poor's 500 Index (S&P 500) is a capitalization-weighted index,
representing the aggregate market value of the common equity of 500 stocks
primarily traded on the New York Stock Exchange.  This chart assumes an initial
gross investment of $10,000 made on September 30, 1994.  Returns shown include
the reinvestment of all dividends.  Past performance is not predictive of future
performance.  The graph and table do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Investment return and principal value will fluctuate, so that your shares, when
redeemed, may be worth more or less than the original cost.

THE MERGER FUND
EXPENSE EXAMPLE
SEPTEMBER 30, 2004

As a shareholder of the Fund, you incur two types of costs: (1) redemption fees
and (2) ongoing costs, including management fees; distribution and/or service
fees; and other Fund expenses. This Example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.  The Example is
based on an investment of $1,000 for the period 4/1/04 - 9/30/04.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. Although the Fund charges no sales load or
transaction fees, you will be assessed fees for outgoing wire transfers,
returned checks and stop-payment orders at prevailing rates charged by U.S.
Bancorp Fund Services, LLC, the Fund's transfer agent.  If you request that a
redemption be made by wire transfer, a $15.00 fee will be charged by the Fund's
transfer agent.  You will be charged a redemption fee equal to 2.00% of the net
amount of the redemption if you redeem your shares less than 30 calendar days
after you purchase them.  IRA accounts will be charged a $15.00 annual
maintenance fee.  To the extent the Fund invests in shares of other investment
companies as part of its investment strategy, you will indirectly bear your
proportionate share of any fees and expenses charged by the underlying funds in
which the Fund invests in addition to the expenses of the Fund.  Actual expenses
of the underlying funds are expected to vary among the various underlying funds.
These expenses are not included in the example below.  The example below
includes, but is not limited to, management fees, shareholder servicing fees,
fund accounting, custody and transfer agent fees.  However, the example below
does not include portfolio trading commissions and related expenses, interest
expense or dividends on short positions held by the Fund and other extraordinary
expenses as determined under generally accepted accounting principles.  You may
use the information in this line, together with the amount you invested, to
estimate the expenses that you paid over the period. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number in the first line under the heading
entitled "Expenses Paid During Period'' to estimate the expenses you paid on
your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.  Please note that the expenses shown in the table are meant
to highlight your ongoing costs only and do not reflect any transactional costs,
such as redemption fees. Therefore, the second line of the table is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

(1)<F17>  Net investment income before interest expense and dividends on short
          positions for the years ended September 30, 2004, 2003, 2002, 2001 and
          2000, was $0.00, $0.01, $0.16, $0.27 and $0.47, respectively.
(2)<F18>  Net investment income per share is calculated using ending balances
          prior to consideration of adjustments for permanent book and tax
          differences.
(3)<F19>  Net investment income per share represents net investment income for
          the respective period divided by the monthly average shares of
          beneficial interest outstanding throughout each period.
(4)<F20>  As a result of recent changes in generally accepted accounting
          principles, the Fund has reclassified periodic payments made under
          equity swap agreements, previously included within dividend income,
          interest expense on equity swap contracts, and dividends on short
          positions, as a component of realized gain (loss) in the statement of
          operations.  The effect of this reclassification was to increase
          (reduce) the net investment income ratio for the years ending

          and 0.26%, respectively, and net investment income per share by
          $(0.01), $(0.01), $(0.05), and $0.04, respectively.  This
          reclassification also reduced the ratio of interest expense and
          dividends on short positions for the years ended September 30, 2003,
          2002, 2001 and 2000 by 0.33%, 0.05%, 0.02%, and 0.31%, respectively.

                                THE MERGER FUND
                       NOTES TO THE FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2004

NOTE 1 -- ORGANIZATION

     The Merger Fund (the "Fund") is a no-load, open-end, non-diversified
investment company organized as a trust under the laws of the Commonwealth of
Massachusetts on April 12, 1982, and registered under the Investment Company Act
of 1940, as amended (the "1940 Act"). The Fund was formerly known as the Risk
Portfolio of The Ayco Fund. In January of 1989, the Fund's fundamental policies
were amended to permit the Fund to engage exclusively in merger arbitrage. At
the same time, Westchester Capital Management, Inc. became the Fund's investment
adviser, and the Fund began to do business as The Merger Fund. Merger arbitrage
is a highly specialized investment approach generally designed to profit from
the successful completion of proposed mergers, takeovers, tender offers,
leveraged buyouts, liquidations and other types of corporate reorganizations.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

A.   Investment Valuation

     Securities listed on the NASDAQ National Market are valued at the NASDAQ
Official Closing Price ("NOCP").  Other listed securities are valued at the last
sales price on the exchange on which such securities are primarily traded or, in
the case of options, at the higher of the intrinsic value of the option or the
last reported composite sales price. Securities not listed on an exchange and
securities for which there are no transactions are valued at the average of the
closing bid and asked prices.  When pricing options, if no sales are reported or
if the last sale is outside the bid and asked parameters, the higher of the
intrinsic value of the option or the mean between the last reported bid and
asked prices will be used.  Securities for which there are no such valuations
are valued at fair value as determined in good faith by management under the
supervision of the Board of Trustees. The Adviser (as defined herein) reserves
the right to value securities, including options, at prices other than last-sale
prices, intrinsic value prices, or the average of closing bid and asked prices
when such prices are believed unrepresentative of fair market value as
determined in good faith by the Adviser.  When fair-valued pricing is employed,
the prices of securities used by the Fund to calculate its NAV may differ from
quoted or published prices for the same securities. In addition, due to the
subjective and variable nature of fair value pricing, it is possible that the
value determined for a particular asset may be materially different from the
value realized upon such asset's sale. At September 30, 2004, the Adviser did
not fair value any long securities.  Investments in United States government
securities (other than short-term securities) are valued at the average of the
quoted bid and asked prices in the over-the-counter market. Short-term
investments are carried at amortized cost, which approximates market value.

B.   Short Positions

     The Fund may sell securities or currencies short for hedging purposes. For
financial statement purposes, an amount equal to the settlement amount is
included in the Statement of Assets and Liabilities as an asset and an
equivalent liability. The amount of the liability is subsequently marked-to-
market to reflect the current value of the short position. Subsequent
fluctuations in the market prices of securities or currencies sold, but not yet
purchased, may require purchasing the securities or currencies at prices which
may differ from the market value reflected on the Statement of Assets and
Liabilities.

     The Fund is liable for any dividends payable on securities while those
securities are in a short position. As collateral for its short positions, the
Fund is required under the 1940 Act to maintain assets consisting of cash, cash
equivalents or liquid securities. These assets are required to be adjusted daily
to reflect changes in the value of the securities or currencies sold short.

C.   Transactions with Brokers for Short Sales

     The Fund's receivable from brokers for proceeds on securities sold short
and deposit at brokers for short sales are with three major securities dealers.
The Fund does not require the brokers to maintain collateral in support of the
receivable from the broker for proceeds on securities sold short.

D.   Federal Income Taxes

     No provision for federal income taxes has been made since the Fund has
complied to date with the provisions of the Internal Revenue Code applicable to
regulated investment companies and intends to continue to so comply in future
years and to distribute investment company net taxable income and net capital
gains to shareholders. Additionally, the Fund intends to make all required
distributions to avoid federal excise tax.

E.   Written Option Accounting

     The Fund writes (sells) covered call options to hedge portfolio
investments. Uncovered put options can also be written by the Fund as part of a
merger arbitrage strategy involving a pending corporate reorganization. When the
Fund writes (sells) an option, an amount equal to the premium received by the
Fund is included in the Statement of Assets and Liabilities as an asset and an
equivalent liability. The amount of the liability is subsequently marked-to-
market to reflect the current value of the option written. By writing an option,
the Fund may become obligated during the term of the option to deliver or
purchase the securities underlying the option at the exercise price if the
option is exercised. Option contracts are valued at the higher of the intrinsic
value of the option or the last sales price reported on the date of valuation.
If no sale is reported or if the last sale is outside the parameters of the
closing bid and asked prices, the option contract written is valued at the
higher of the intrinsic value of the option or the mean between the last
reported bid and asked prices on the day of valuation. When an option expires on
its stipulated expiration date or the Fund enters into a closing purchase
transaction, the Fund realizes a gain or loss if the cost of the closing
purchase transaction differs from the premium received when the option was sold
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is eliminated. When an option is exercised,
the premium originally received decreases the cost basis of the security (or
increases the proceeds on a sale of the security), and the Fund realizes a gain
or loss from the sale of the underlying security.

F.   Purchased Option Accounting

     The Fund purchases put options to hedge portfolio investments. Call options
may be purchased only for the purpose of closing out previously written covered
call options. Premiums paid for option contracts purchased are included in the
Statement of Assets and Liabilities as an asset. Option contracts are valued at
the higher of the intrinsic value of the option or the last sales price reported
on the date of valuation. If no sale is reported or if the last sale is outside
the parameters of the closing bid and asked prices, the option contract
purchased is valued at the higher of the intrinsic value of the option or the
mean between the last reported bid and asked prices on the day of valuation.
When option contracts expire or are closed, realized gains or losses are
recognized without regard to any unrealized gains or losses on the underlying
securities.

G.   Forward Currency Exchange Contracts

     The Fund may enter into forward currency exchange contracts obligating the
Fund to deliver and receive a currency at a specified future date. Forward
contracts are valued daily, and unrealized appreciation or depreciation is
recorded daily as the difference between the contract exchange rate and the
closing forward rate applied to the face amount of the contract. A realized gain
or loss is recorded at the time the forward contract is closed.

H.   Distributions to Shareholders

     Dividends from net investment income and net realized capital gains, if
any, are declared and paid annually. Income and capital gain distributions are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. These differences are due primarily to
wash loss deferrals, constructive sales, straddle loss deferrals, adjustments on
equity swaps, and unrealized gains or losses on Section 1256 contracts, which
were realized, for tax purposes, at September 30, 2004. Accordingly,
reclassifications are made within the net asset accounts for such amounts, as
well as amounts related to permanent differences in the character of certain
income and expense items for income tax and financial reporting purposes. The
Fund may utilize earnings and profits deemed distributed to shareholders on
redemption of shares as part of the dividends-paid-deduction.

I.   Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

J.   Foreign Securities

     Investing in securities of foreign companies involves special risks and
considerations not typically associated with investing in U.S. companies. These
risks include revaluation of currencies and adverse political and economic
developments. Moreover, securities of many foreign companies and their markets
may be less liquid and their prices more volatile than those of securities of
comparable U.S. companies.

K.   Foreign Currency Translations

     The books and records of the Fund are maintained in U.S. dollars. Foreign
currency transactions are translated into U.S. dollars on the following basis:
(i) market value of investment securities, assets and liabilities at the daily
rates of exchange, and (ii) purchases and sales of investment securities,
dividend and interest income and certain expenses at the rates of exchange
prevailing on the respective dates of such transactions. For financial reporting
purposes, the Fund does not isolate changes in the exchange rate of investment
securities from the fluctuations arising from changes in the market prices of
securities. However, for federal income tax purposes, the Fund does isolate and
treat as ordinary income the effect of changes in foreign exchange rates on
realized gain or loss from the sale of investment securities and payables and
receivables arising from trade-date and settlement-date differences.

L.   When-Issued Securities

     The Fund may sell securities on a when-issued or delayed-delivery basis.
Although the payment and interest terms of these securities are established at
the time the Fund enters into the agreement, these securities may be delivered
for cash proceeds at a future date. The Fund records sales of when-issued
securities and reflects the values of such securities in determining net asset
value in the same manner as other open short-sale positions. The Fund segregates
and maintains at all times cash, cash equivalents or other liquid securities in
an amount at least equal to the market value for when-issued securities.

M.   Reporting of Swap Contracts

     As a result of a recent FASB Emerging Issues Task Force consensus and
subsequent related SEC staff guidance, the Fund has reclassified periodic
payments made under equity swap agreements, previously included within dividend
income, interest expense on equity swap contracts, and dividends on short
positions, as a component of realized gain (loss) in the statement of
operations.  For consistency, similar reclassifications have been made to
amounts appearing in the previous year's statement of changes in net assets and
the per-share amounts in the previous years' financial highlights.  The previous
years' net-investment-income ratios in the financial highlights have also been
modified accordingly.  This reclassification increased (decreased) net
investment income by $(1,045,740), $(467,783), $(3,719,964) and $2,045,083 for
the years ended September 30, 2003, 2002, 2001, and 2000, respectively, but had
no effect on the Fund's net asset value, either in total or per share.  The
reclassification of net investment income was offset by an increase (decrease)
in net realized gains.

N.   Guarantees and Indemnifications

     In the normal course of business, the Fund enters into contracts with
service providers that contain general indemnification clauses.  The Fund's
maximum exposure under these arrangements is unknown, as this would involve
future claims that may be made against the Fund that have not yet occurred.
However, based on experience, the Fund expects the risk of loss to be remote.

O.   Other

     Investment and shareholder transactions are recorded on the trade date.
Realized gains and losses from security transactions are recorded on the
identified cost basis. Dividend income and distributions to shareholders are
recorded on the ex-dividend date. Interest is accounted for on the accrual
basis. Investment income includes $2,494,025 of interest earned on receivables
from brokers for proceeds on securities sold short and deposits. The Fund may
utilize derivative instruments such as options, forward currency exchange
contracts and other instruments with similar characteristics to the extent that
they are consistent with the Fund's investment objectives and limitations. The
use of these instruments may involve additional investment risks, including the
possibility of illiquid markets or imperfect correlation between the value of
the instruments and the underlying securities.

NOTE 3 -- AGREEMENTS

     The Fund's investment adviser is Westchester Capital Management, Inc. (the
"Adviser") pursuant to an investment advisory agreement dated January 31, 1989.
Under the terms of this agreement, the Adviser is entitled to receive a fee,
calculated daily and payable monthly, at the annual rate of 1.00% of the Fund's
average daily net assets. Effective August 1, 2004, the Adviser agreed to
voluntarily waive 0.10% of its fee at net asset levels between $1.5 billion
through $2 billion.  When net assets of the Fund exceed $2 billion, the Adviser
has voluntarily agreed to waive 0.20% of its fee.  Certain officers of the Fund
are also officers of the Adviser.

     U.S. Bancorp Fund Services, LLC, a subsidiary of U.S. Bancorp, a publicly
held bank holding company, serves as transfer agent, administrator and
accounting services agent for the Fund. U.S. Bank, N.A. serves as custodian for
the Fund.

     Distribution services are performed pursuant to distribution contracts with
broker-dealers and other qualified institutions.  Prior to its resignation on
June 30, 2003, Mercer Allied Company, L.P. served as the Fund's principal
underwriter.  The Fund has not had a principal underwriter since such date.

NOTE 7 -- DISTRIBUTION PLAN

     The Fund has adopted a Plan of Distribution (the "Plan") dated July 1,
1993, as amended, pursuant to Rule 12b-1 under the 1940 Act. Under the Plan, the
Fund will compensate broker-dealers or qualified institutions with whom the Fund
has entered into a contract to distribute Fund shares ("Dealers"). Under the
Plan, the amount of such compensation paid in any one year shall not exceed
0.25% annually of the average daily net assets of the Fund, which may be payable
as a service fee for providing recordkeeping, subaccounting, subtransfer agency
and/or shareholder liaison services. For the year ended September 30, 2004, the
Fund incurred $3,547,045 pursuant to the Plan.

     The Plan will remain in effect from year to year provided such continuance
is approved at least annually by a vote either of a majority of the Trustees,
including a majority of the non-interested Trustees, or a majority of the Fund's
outstanding shares.

NOTE 8 -- CREDIT FACILITY

     Custodial Trust Company has made available to the Fund a $230 million
credit facility (subject to increase under certain conditions) pursuant to a
Loan and Security Agreement ("Agreement") dated March 18, 1992 (subsequently
amended) for the purpose of purchasing portfolio securities. The Agreement can
be terminated by either the Fund or Custodial Trust Company with three months'
prior notice. As collateral for the loan, the Fund is required under the 1940
Act to maintain assets consisting of cash, cash equivalents or liquid
securities. The assets are required to be adjusted daily to reflect changes in
the amount of the loan outstanding.  During the year ended September 30, 2004
the Fund did not have any borrowings outstanding under the Agreement.

NOTE 9 -- FORWARD CURRENCY EXCHANGE CONTRACTS

     At September 30, 2004, the Fund had entered into "position hedge" forward
currency exchange contracts that obligated the Fund to deliver or receive
currencies at a specified future date. The net unrealized depreciation of

NOTE 10 -- EQUITY SWAP CONTRACTS

     The Fund has entered into both long and short equity swap contracts with
multiple broker-dealers. A long equity swap contract entitles the Fund to
receive from the counterparty any appreciation and dividends paid on an
individual security, while obligating the Fund to pay the counterparty any
depreciation on the security as well as interest on the notional amount of the
contract at a rate equal to LIBOR plus 25 to 100 basis points. A short equity
swap contract obligates the Fund to pay the counterparty any appreciation and
dividends paid on an individual security, while entitling the Fund to receive
from the counterparty any depreciation on the security as well as interest on
the notional value of the contract at a rate equal to LIBOR less 25 to 100 basis
points.

     The Fund may also enter into equity swap contracts whose value is
determined by the spread between a long equity position and a short equity
position. This type of swap contract obligates the Fund to pay the counterparty
an amount tied to any increase in the spread between the two securities over the
term of the contract. The Fund is also obligated to pay the counterparty any
dividends paid on the short equity holding as well as any net financing costs.
This type of swap contract entitles the Fund to receive from the counterparty
any gains based on a decrease in the spread as well as any dividends paid on the
long equity holding and any net interest income.

     Fluctuations in the value of an open contract are recorded daily as a net
unrealized gain or loss. The Fund will realize a gain or loss upon termination
or reset of the contract. Either party, under certain conditions, may terminate
the contract prior to the contract's expiration date.

     Credit risk may arise as a result of the failure of the counterparty to
comply with the terms of the contract. The Fund considers the creditworthiness
of each counterparty to a contract in evaluating potential credit risk. The
counterparty risk to the Fund is limited to the net unrealized gain, if any, on
the contract, along with dividends receivable on long equity contracts and
interest receivable on short equity contracts. Additionally, risk may arise from
unanticipated movements in interest rates or in the value of the underlying
securities. At September 30, 2004, the Fund had the following open equity swap
contracts:


                                                                              UNREALIZED APPRECIATION

     For the year ended September 30, 2004, the Fund realized gains of
$27,492,357 upon the termination of equity swap contracts.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of
The Merger Fund

In our opinion, the accompanying statement of assets and liabilities, including
the schedules of investments, of securities sold short, and of options written,
and the related statements of operations and of changes in net assets and the
financial highlights present fairly, in all material respects, the financial
position of The Merger Fund (the "Fund") at September 30, 2004, the results of
its operations, the changes in its net assets and its financial highlights for
the periods presented, in conformity with accounting principles generally
accepted in the United States of America.  These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund'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 the standards of the
Public Company Accounting Oversight Board (United States).  Those standards
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 September 30, 2004, by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

As discussed in Note 2M to the financial statements, the Fund changed its method
of accounting for amounts received and payments made under equity swap
agreements in 2004.
