THE MERGER FUND EXPENSE EXAMPLE MARCH 31, 2006 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 10/01/05 - 3/31/06. 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 MARCH 31, 2006 (UNAUDITED) 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 March 31, 2006 fair-valued long securities represented 1.97% 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 $6,630,000 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.

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 six months ended March 31, 2006, the Fund incurred $1,441,237 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 $400 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. For the period October 1, 2005 to March 31, 2006, the interest rate on the outstanding principal amount was the Federal Funds Rate plus 0.75% (weighted average rate of 4.86% during the six months ended March 31, 2006). Advances are collateralized by securities owned by the Fund and held separately in a special custody account pursuant to a Special Custody Agreement dated March 31, 1994. During the six months ended March 31, 2006, the Fund had an outstanding average daily balance of $160,195,099. The maximum amount outstanding during the six months ended March 31, 2006 was $355,058,000. At March 31, 2006, the Fund had a loan-payable balance of $0. 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. NOTE 9 -- FORWARD CURRENCY EXCHANGE CONTRACTS At March 31, 2006, 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.

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 March 31, 2006, the Fund had the following open equity swap contracts: UNREALIZED APPRECIATION TERMINATION DATE SECURITY SHARES (DEPRECIATION) ---------------- -------- ------ -------------- 6/30/06-7/15/06 BAA PLC 1,413,331 $ 198,014 9/10/06 BOC Group PLC 2,143,063 (422,473) 5/19/06 London Stock Exchange 200,000 (466,064) 4/21/06 London Stock Exchange 500,000 (729,000) 4/21/06 London Stock Exchange April Call (500,000) 625,575 5/19/06 London Stock Exchange May Call (200,000) 346,884 7/15/06 McClatchy Company (50,000) 53,523 4/21/06 Prudential April Call (250,000) 25,050 4/21/06 Prudential PLC 250,000 (75,700) 4/1/06 Schering April Call (272,600) (352,382) 4/1/06 Schering April Call (189,400) (209,161) 6/30/06 Telesystem International Wireless Inc. 904,334 69,724 6/30/06 Telesystem International Wireless Inc. 310,000 (285,939) 6/30/06 Telesystem International Wireless Inc. 2,940,190 (37,928) ----------- $(1,259,877) ----------- ----------- For the six months ended March 31, 2006, the Fund realized losses of $188,656 upon the termination of equity swap contracts. Such losses may have been offset by gains on related long or short equity positions or forward currency exchange contracts. THE MERGER FUND APPROVAL OF ADVISORY CONTRACT On January 21, 2006, at a meeting called for the purpose of voting on such approval, the Board of Trustees, including all of the Trustees who are not parties to the Advisory Contract or interested persons of any such party (the non-interested Trustees), approved the continuance of the Advisory Contract for the Fund. In so doing, the Board studied materials specifically relating to the Advisory Contract provided by the Adviser, counsel to the non-interested Trustees and counsel to the Fund. The Board considered a variety of factors, including the following: The Board considered the nature, extent and quality of the services to be provided by the Adviser to the Fund pursuant to the Advisory Contract, including the Adviser's competence and integrity; research capabilities; implementation and enforcement of compliance procedures and financial-reporting controls; and adherence to the Fund's investment objectives, policies and restrictions. The Board also reviewed the Adviser's methodology, research and analysis that it employs in selecting investments for the Fund. The Board considered the non- traditional nature of the Fund's investment approach, the specialized expertise and experience of the Fund's portfolio managers and the difficulty, were it warranted, of selecting an alternative adviser. The Board also evaluated the investment performance of the Fund relative to the S&P 500 Index over the last year, three years, five years and 10 years, and relative to the performance of alternative-investment mutual funds, including those that engage in merger arbitrage. Additionally, the Board reviewed information on the fee structure of the Advisory Contract, including the costs of the services to be provided and the profits to be realized by the Adviser and its affiliate from their relationship with the Fund, as evidenced by the Adviser's profitability analysis. The profitability analysis consisted of income and expenses by category for calendar years 2005 and 2004, less expenses allocated to other funds managed by the Adviser's affiliate, adjusted total expenses, net income, profit margin and profit margin before payments to fund supermarkets. The Board also reviewed comparisons of the rates of compensation paid to managers of funds in its peer group, Lipper data relating to average expenses and advisory fees for comparable funds and the benefit to the Adviser of the Fund's soft-dollar arrangements. It was noted that the Adviser's future profit margin is expected to decline modestly as the Adviser absorbs additional expenses for hardware and financial newswires. Based on the information provided, the Board determined that the Fund's fee structure is competitive with funds with similar investment goals and strategies. The Board considered the Fund's total expense ratio, contractual investment advisory fees, 12b-1 distribution expense and service-provider fee ratio compared to the industry average by quartile, within the appropriate Lipper benchmark category and Lipper category range. The Board also considered the amount and nature of fees paid by shareholders. The Board considered the fact that the Adviser has agreed to waive a portion of its fees and noted that the fee waiver could be discontinued at any time after January 31, 2007. The Adviser provided information on peer-group comparisons consisting of alternative-investment mutual funds, including those that engage in merger arbitrage. The materials compared each fund's investment strategies; management fee; expense ratio; total assets; whether a fund has a breakpoint, charges a sales load and is open to new investors; returns for the one year, three years, five years and 10 years ended December 31, 2005; and risk as measured by beta and standard deviation. It was noted that the Fund's management fees and expense ratio are within the average range compared to its peer funds. The Board considered the extent to which economies of scale would be realized with respect to operational costs as the Fund grows in the number of shareholders and assets under management, the existence of breakpoints previously established by the Adviser, and whether fee levels to be charged by the Adviser reflect these economies of scale for the benefit of Fund investors and are fair under the circumstances, which the Board, including all of the non- interested Trustees, believed to be the case. Based on its evaluation, in consultation with independent counsel, of all material aspects of the Advisory Contract, including the foregoing factors and such other information believed to be reasonably necessary to evaluate the terms of the Advisory Contract, the Board, including all of the non-interested Trustees voting separately, concluded that the continuation of the Advisory Contract would be in the best interest of the Fund's shareholders, and determined that the compensation to the Adviser provided for in the Advisory Contract is fair and reasonable.
