                               SEPTEMBER 30, 2005

                                                               November 16, 2005

Dear Fellow Shareholder:

  As previously reported, The Merger Fund(R) showed a gain of 5.9% in its
fiscal year ended September 2005.  A healthy level of M&A activity provided the
Fund with a tailwind during much of this period, but we did encounter a few
pockets of turbulence that weighed on our results.  More specifically, of the
approximately 200 arbitrage situations in which we held positions during fiscal
2005, 12, or about 6%, were either terminated, renegotiated or put at risk by
issues that remained unresolved at the end of September.  In fiscal 2004,
roughly 10% of our investments fell into the "troubled" category.  We'd like to
think that this year-over-year improvement was due entirely to better deal
selection on our part, but a long career in merger arbitrage has taught us that
a little luck doesn't hurt, either.  Rounding out the list of the most important
drivers of the Fund's performance, arbitrage spreads-the percentage profit to be
made on successful deals-were generally a little more favorable in the 12 months
ended September.  Because many arbitrageurs use borrowed funds to enhance
returns, the upward trend in short-term interest rates has led to higher rate-
of-return requirements and wider spreads on newly announced deals.

  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 more than 98% of the dollar value of our equity holdings, while
unsolicited, or hostile, takeover attempts accounted for less than 2%.  The
latter figure, which is down from 5% a year earlier, indicates that hostile
deals continue to make up a relatively small percentage of total M&A activity.
Many would-be acquirers apparently have concluded that friendly takeovers are
hard enough to get right and that hostile deals are even more problematic.  Such
concerns are well-founded.  As we have noted on numerous occasions over the
years, for a hostile takeover attempt to succeed, the stars must be in perfect
alignment  for the bidder, and such opportunities come around about as often as
Halley's Comet.  Not only are target companies routinely protected by poison
pills, staggered boards and other takeover defenses that have withstood legal
challenge, but many companies have also chosen to be legally domiciled in states
whose corporate-governance statutes are especially unfriendly to hostile
suitors.  Presumed by the courts to be acting in their shareholders' best
interests, corporate boards are generally free to reject unsolicited offers out
of hand, even richly valued bids that would have the support of those very same
shareholders.  Only a highly motivated acquirer willing to wage a protracted
battle can hope to prevail against the "just say no" defense, and even with such
a commitment, victory is not assured; at the eleventh hour, a white knight may
agree to pay more and steal the prize.  In last year's annual report, we wrote
about Oracle's dogged pursuit of PeopleSoft, an effort that eventually succeeded
but only after the buyer invested 19 months in the process.  This year's award
for the most-persistent suitor goes to Omnicare, which finally was able to
acquire rival NeighborCare after a struggle that lasted 14 months.  To put this
award in perspective, however, there were very few other candidates.

  Chart 2 shows that approximately 88% 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.
At the end of September, financial transactions represented about 12% of our
arbitrage investments, up from 7% a year earlier and the highest level since we
started keeping this statistic in 1996.   Although there are multiple
explanations for the fact that financial players now account for a bigger share
of M&A activity, at the top of the list is the vast pile of cash available for
leveraged deals.  Buyout firms are estimated to have access to as much as $150
billion in uncommitted equity capital.  These funds, in turn, can be leveraged
several times over with debt financing.  And the increased willingness of
financial buyers to work together on certain deals-seven private-equity firms
took part in the $11 billion purchase of SunGard Data Systems-means that even
larger targets can be pursued, with the result that relatively few publicly
traded companies are too big to be taken private.  These "club" deals also help
to avoid bidding contests among private-equity shops.  Another reason for the
upturn in going-private deals is that a growing number of corporate executives
have become frustrated with the burdens of public ownership, including
compliance with Sarbanes-Oxley, an unprecedented degree of scrutiny by
regulators and the financial press, shareholder activism and Wall Street's
obsession with short-term results.  For these executives, the choice between
continuing to operate in a goldfish bowl and taking a shot at  making serious
money with a successful LBO may not be that close a call.  From a merger-
arbitrage perspective, we tend to prefer strategic deals to LBOs because the
latter have historically been a little more accident-prone, and we adjust our
rate-of-return requirements accordingly.

  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 shows that when it comes
to deal-making, cash is king.  Mergers and acquisitions involving at least some
cash make up 73% of the Fund's portfolio, while all-stock transactions account
for just 13%, down from 33% two years ago.  The growing preference for cash can
be explained by the same factors that we discussed in last year's annual report:
the reluctance of many acquirers to issue new shares at what they 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, especially when borrowing
costs remain relatively low; the upturn in going-private transactions, in which
the target's shareholders receive only cash; and the preference of some sellers
for cash deals, whose value is unaffected by fluctuations in equity prices.
Another factor is at work this year.  Corporate balance sheets are bulging with
cash, and using a portion of it to make acquisitions may be a strategically
attractive option for many companies.  Spending excess cash for takeovers can
serve another purpose, as well.  Cash-heavy balance sheets sometimes attract
activist shareholders who demand large stock buybacks or special dividends,
options that may not be in the company's best interests on a longer-term basis.
In evaluating potential arbitrage investments for the Fund, the mix of cash and
stock to be received is generally not that important to us, but deal terms do
impact our hedging strategies.  When investing in stock-for-stock mergers with
fixed exchange ratios, we 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.

  Chart 4 shows our investments grouped by economic sector.  The Fund's
holdings continue to be fairly well diversified, with no sector accounting for
more than 20% of the portfolio.  For the second year in a row, healthcare deals
represent the largest percentage of our investments, while the financial-
services sector, historically a fertile area for M&A, has moved into second
place.  The biggest change from fiscal 2004 is the decline in the Fund's
exposure to telecommunications, a sector which last year represented 18% of our
holdings but now accounts for just 4%.  The past year saw a number of large
telecom mergers, but few of these deals appeared to offer compelling arbitrage
opportunities, and we chose to invest elsewhere.  The consumer non-durables
sector, which includes food and beverage companies, clothing manufacturers and
suppliers of other consumer staples, now represents the Fund's third-largest
exposure, up from just 6% a year earlier.  Because we take a "bottom- up"
approach to deal selection, the issues that are specific to a given merger or
takeover play a much greater role in our analysis than such "macro" factors as
the sector in which the companies operate.  Having said that, we do attempt to
diversify our investments by industry group in order to make the Fund less
vulnerable to systemic risk, or the risk that unexpected industry-specific
events could adversely impact a number of pending deals at the same time.

  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 2005,
approximately 86% of the deals in our portfolio involved U.S.-based targets,
while 14% involved targets located in Canada, Europe and Asia.  A year earlier,
non-U.S. deals accounted for about 9% of our investments.  Although The Merger
Fund(R) has the resources and expertise to invest globally, we recognize that
foreign deals play out against a different political, corporate-governance and
regulatory backdrop than comparable transactions in the U.S., and the Fund won't
invest overseas unless we have done our homework and have a firm handle on the
risks involved.  Speaking of risks, the Fund routinely hedges 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.  The chart indicates that M&A activity has recovered
smartly from the depressed levels of 2002 but remains well below the record pace
seen in the 1998-2000 period, when the annual volume of corporate
reorganizations averaged close to $1.5 trillion.  Of the many reasons for the
recent strength in deal-making, probably the most important is the return of
confidence to corporate boardrooms.  A few years ago, executives had to deal
with the aftermath of 9/11 and the attendant economic and geopolitical
uncertainties.  At about the same time, a wave of accounting scandals raised
questions about the adequacy of Corporate America's financial controls, and
directors were reluctant to greenlight acquisitions until they could be assured
that their own house was in order and that the financial statements of potential
targets could be relied upon.  Now that the U.S. economy has shown its
resiliency-even in the face of record trade and budget deficits and soaring
energy prices-and accounting-related concerns have been addressed, executives
are better able to focus on how to position their companies for the long term.
This is a process that often involves consideration of mergers, acquisitions or
some other type of corporate reorganization.  Investment bankers have another
reason to be optimistic these days.  An increasing number of newly announced
transactions are being well-received by investors.  Transformational deals that
take the acquirer in an entirely new direction or acquisitions dependent on
aggressive assumptions regarding revenue synergies are still a hard sell, but
straightforward combinations that promise realistic cost savings are now often
given the benefit of the doubt, especially if the takeover premium is not too
generous.  Absent an external shock to the system, we expect that M&A activity
will remain strong and that the Fund will have a good supply of new deals in
which to invest.
                                      Sincerely,

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, 1995.  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, 2005

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 4/01/05 - 9/30/05.

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, 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.

                                THE MERGER FUND
                       NOTES TO THE FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2005

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, 2005 fair-valued long
securities represented 5.95% of investments, at value.  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 swap contracts, and unrealized gains or losses on Section 1256 contracts,
which were realized, for tax purposes, at September 30, 2005. 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 decreased accumulated net investment loss by $5,053,286, reduced realized
accumulated gains by $7,405,945, and increased paid-in capital by $2,352,659.
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.   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.

N.   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 $5,795,579 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 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 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.

NOTE 4 -- SHARES OF BENEFICIAL INTEREST

     The Trustees have the authority to issue an unlimited amount of shares of
beneficial interest without par value.

     Changes in shares of beneficial interest were as follows:

NOTE 7 -- DISTRIBUTION PLAN

     The Fund has adopted an Amended and Restated Plan of Distribution (the

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,
2005, the Fund incurred $3,425,548 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

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.  For the period October 1, 2004 to September 30, 2005, the
interest rate on the outstanding principal amount was the Federal Funds Rate
plus 0.75% (weighted average rate of 4.32% during the year ended September 30,

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, 2005, the Fund had the following open equity swap
contracts:


                                                                                    UNREALIZED APPRECIATION

            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, of cash flows 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, 2005,
the results of its operations for the year then ended, the changes in its net
assets for each of the two years in the period then ended and the financial
highlights for each of the five years in the period then ended, 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, 2005 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

least one audit committee financial expert serving on its audit committee.
Michael J. Downey and James P. Logan, III are audit committee financial experts
and are considered to be independent as each term is defined in Item 3 of

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.
- -----------------------------------------------

The registrant has engaged its principal accountant to perform audit services
and tax services during the past two fiscal years. "Audit services" refer to
performing an audit of the registrant's annual financial statements or services
that are normally provided by the accountant in connection with statutory and
regulatory filings or engagements for those fiscal years. "Tax services" refer
to professional services rendered by the principal accountant for tax
compliance, tax advice, and tax planning.  The following table details the
aggregate fees billed or expected to be billed for each of the last two fiscal
years for audit fees and tax fees by the principal accountant.

All Other Fees

The audit committee has adopted pre-approval policies and procedures that
require the audit committee to pre-approve all audit and non-audit services of
the registrant, including services provided to any entity affiliated with the
registrant.  The audit committee approved 100% of the tax services provided by
the registrant's principal accountant.  All of the principal accountant's hours
spent on auditing the registrant's financial statements were attributed to work
performed by full-time permanent employees of the principal accountant.

There were no non-audit fees billed by the registrant's accountant for services
to the registrant and to the registrant's investment adviser, and any entity
controlling, controlled by, or under common control with the investment adviser
