Looking back at the letter enclosed in last year's Annual Report, one cannot help but observe what a difference a year makes. In that letter, we noted that signs of a healthy merger arbitrage market were at hand and that although the widening of spreads might provide a minor or temporary drag on returns, the situation of negligible dealflow and low interest rates was rapidly reversing itself to the benefit of merger arbitrage. In fact, it was and, as a result, the Fund's Class R Shares generated a return of 7.15% for the 12 months ending May 31, 2006. Since our last Annual Report to you, the two key drivers of profits in merger arbitrage: (1) higher interest rates and (2) normalized dealflow (in that order) have indeed improved substantially. Short term rates are double what they were in June 2004, and more than quadruple where they stood in January 2004. Since profit margins (i.e. spreads) in merger arbitrage track short term rates, we believe the profit potential in merger arbitrage is considerably greater than it has been at any time since 2000. Similarly, though less critically, dealflow is at record levels. In fact, during the past 12 months we have witnessed a greater level of merger transactions (both in number of transactions and dollar value) than we have seen in half a decade. We expect this trend to continue through the balance of this year, driven in large part by globalization of the world's major economies. We say, however, that record dealflow, while clearly a boon for arbitrageurs, is "less critical" because whether or not deal volume breaks records or continues at current levels, The Arbitrage Fund is well positioned to profit from the wider spreads that result from higher short term interest rates as long as deal volume remains within historical norms. It is also worth noting in the current volatile market that mergers occur in both up markets and down ones and that some of the best acquisition opportunities may frequently appear in difficult or volatile markets. For these reasons, we are pleased to report to you that our predictions regarding an improved merger arbitrage environment have proven accurate and our efforts have borne fruit in the form of improved returns. We strongly believe that the merger market remains in the first stage of an extended recovery both at home and abroad and that that recovery will continue for several years to come. Record dealflow or not, we believe higher and more stable short term interest rates are here to stay, and that should bode well for the Fund's performance. 1 We thank you for your continued support and renew again our commitment to provide our shareholders with capital appreciation consistent with the overriding principle of capital preservation. Please also know that, as always, we welcome your calls. Sincerely, /s/ John S. Orrico John S.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES The Arbitrage Fund (the "Trust") was organized as a Delaware business trust on December 22, 1999 and is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company issuing its shares in series, each series representing a distinct portfolio with its own investment objective and policies. The one series presently authorized is The Arbitrage Fund (the "Fund"), a diversified series, which offers two classes of shares. Class R shares and Class I shares commenced operations on September 17, 2000 and October 17, 2003, respectively. The investment objective of the Fund is to achieve capital growth by engaging in merger arbitrage. The Fund's two classes of shares, Class R and Class I, represent interests in the same portfolio of investments and have the same rights, but differ primarily in the expenses to which they are subject and the investment eligibility requirements. Class R shares are subject to an annual distribution fee of up to ..25% of the Fund's average daily net assets attributable to Class R shares, whereas Class I shares are not subject to any distribution fees. The following is a summary of the Fund's significant accounting policies: USE OF ESTIMATES - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. VALUATION OF INVESTMENTS - The Fund's portfolio securities are valued as of the close of business of the regular session of the New York Stock Exchange ("NYSE") (normally 4:00 p.m., Eastern time). Common stocks and other securities, including open short positions, that are traded on a securities exchange are valued at the last quoted sales price at the close of regular trading on the day the valuation is made. Securities which are quoted by NASDAQ are valued at the NASDAQ Official Closing Price. Price information on listed stocks is taken from the exchange where the security is primarily traded. Securities which are listed on an exchange but which are not traded on the valuation date are valued at the mean of the most recent bid and asked prices. Put and call options and securities traded in the over-the-counter market are valued at the mean of the most recent bid and asked prices. Unlisted securities for which market quotations are readily available are valued at the latest quoted bid price. Other assets and securities for which no quotations are readily available are valued at fair value as determined in good faith under the supervision of the Board of Trustees of the Trust. Some of the more common reasons that may necessitate that a security be valued at fair value include: the security's trading has been halted or suspended; the security has been delisted from a national exchange; the 20 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- security's primary trading market is temporarily closed at a time when under normal conditions it would be open; or the security's primary pricing source is not able or willing to provide a price. Such methods of fair valuation may include, but are not limited to: multiple of earnings, multiple of book value, discount from market of a similar freely traded security, purchase price of a security, subsequent private transactions in the security or related securities, or a combination of these and other factors. Foreign securities are translated from the local currency into U.S. dollars using currency exchange rates supplied by a quotation service (see Note 6). SHARE VALUATION - The net asset value per share of each class of shares of the Fund is calculated daily by dividing the total value of the Fund's assets attributable to that class, less liabilities attributable to that class, by the number of shares of that class outstanding. The offering price and redemption price per share of each class of the Fund is equal to the net asset value per share, except that, shares of each class are subject to a redemption fee of 2% if redeemed within 90 days of the date of purchase. For the year ended May 31, 2006, proceeds from redemption fees were $27,885 in Class R and $147 in Class I. INVESTMENT INCOME - Interest income is accrued as earned. Dividend income and expense are recorded on the ex-dividend date. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - Dividends arising from net investment income and net capital gain distributions, if any, are declared and paid at least annually to shareholders of the Fund. The amount of distributions from net investment income and net realized gains are determined in accordance with Federal income tax regulations which may differ from accounting principles generally accepted in the United States of America. These "book/tax" differences are either temporary or permanent in nature and are primarily due to losses deferred due to wash sales. The tax character of distributions declared during the years ended May 31, 2006 and May 31, 2005 was as follows: - -------------------------------------------------------------------------------- Year Ordinary Long-Term Total Ended Income Capital Gains Distributions - -------------------------------------------------------------------------------- 5/31/06 $ -- $ -- $ -- 5/31/05 $ 10,778,315 $ 1,146,281 $ 11,924,596 - -------------------------------------------------------------------------------- ALLOCATION BETWEEN CLASSES - Investment income earned, realized capital gains and losses, and unrealized appreciation and depreciation are allocated daily to each class of shares based upon its proportionate shares of total net assets of the Fund. Class specific expenses are charged directly to the class incurring the expense. Common expenses which are not attributable to a specific class are allocated daily to each class of shares based upon its proportionate share of total net assets of the Fund. 21 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- SECURITY TRANSACTIONS - Security transactions are accounted for on trade date. Gains and losses on securities sold are determined on a specific identification basis. SHORT POSITIONS - The Fund may sell securities short for economic 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 sold, but not yet purchased, may require purchasing the securities 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. The amount of the collateral is required to be adjusted daily to reflect changes in the value of the securities sold short. WRITTEN OPTION TRANSACTIONS - The Fund may write (sell) covered call options to hedge portfolio investments. Put options may 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 average of the current bid and asked price reported 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). EQUITY SWAP CONTRACTS - The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk. An 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. 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. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the Fund's custodian and/or counterparty's broker. Risks may exceed amounts recognized on the Statements of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap 22 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- agreements. Details of swap agreements open at May 31, 2006 are included in the Fund's Portfolio of Investments and Schedule of Securities Sold Short. As of May 31, 2006, the Fund had long and short equity swap contracts outstanding of $8,746,603 and $865,303, respectively. FEDERAL INCOME TAX - It is the Fund's policy to comply with the special provisions of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. As provided therein, in any fiscal year in which a Fund so qualifies and distributes at least 90% of its taxable net income, the Fund (but not the shareholders) will be relieved of Federal income tax on the income distributed. Accordingly, no provision for income taxes has been made. In order to avoid imposition of the excise tax applicable to regulated investment companies, it is also the Fund's intention to declare as dividends in each calendar year at least 98% of its net investment income (earned during the calendar year) and 98% of its net realized capital gains (earned during the twelve months ended October 31) plus undistributed amounts from prior years. The following information is computed on a tax basis for each item as of May 31, 2006: - -------------------------------------------------------------------------------- Cost of portfolio investments (including securities sold short and written options) $164,010,164 ============ Gross unrealized appreciation $ 6,742,792 Gross unrealized depreciation (4,956,989) Net unrealized appreciation 1,785,803 Net unrealized depreciation on translation of assets and liabilities in foreign currencies (12,069) Undistributed ordinary income 6,724,077 Undistributed long-term capital gain 89,346 Post October losses (4,041,193) Post October currency losses (1,861,087) Other temporary differences (4,061) ------------ Total distributable earnings $ 2,680,816 ============ - -------------------------------------------------------------------------------- The difference between the Federal income tax cost of portfolio investments and the cost reported on the Statement of Assets and Liabilities is due to the tax deferral of losses on wash sales. For the fiscal year ended May 31, 2006, the fund utilized capital loss carryforwards of $1,501,235 to offset net realized capital gains. For the year ended May 31, 2006, the Fund reclassified net investment losses of $915,862 and accumulated net realized losses of $258,357 to paid-in-capital on the Statement of Assets and Liabilities. Such reclassification, the result of permanent differences between financial statement and income tax reporting requirements primarily attributable to reclassification of long term capital gain distributions on Real Estate Investment Trust securities, gains and losses on certain foreign currency related transactions and net 23 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- operating loss and reclassification of short sale related dividend expense to capital loss, have no effect on the Fund's net assets or net asset value per share. 2. INVESTMENT TRANSACTIONS During the year ended May 31, 2006, cost of purchases and proceeds from sales and maturities of investment securities, other than short-term investments, U.S. government securities, options and short positions, amounted to $882,137,360 and $756,576,849, respectively. A summary of put and call option contracts written during the year ended May 31, 2006 is as follows: - -------------------------------------------------------------------------------- OPTION OPTION CONTRACTS PREMIUMS - -------------------------------------------------------------------------------- Options outstanding at beginning of year 3,730 $ 463,871 Options written 69,933 8,961,085 Options canceled in a closing purchase transaction (18,780) (2,922,207) Options exercised (25,368) (3,499,941) Options expired (24,598) (2,339,537) ----------- ----------- Options outstanding at end of year 4,917 $ 663,271 =========== =========== - -------------------------------------------------------------------------------- 3. TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISORY AGREEMENT The Fund's investments are managed by Water Island Capital, LLC (the "Adviser") under the terms of an Investment Advisory Agreement. Under the Investment Advisory Agreement, the Fund pays the Adviser a fee, which is computed and accrued daily and paid monthly, at the annual rate of 1.50% of the Fund's average daily net assets. Until August 31, 2012, the Adviser has contractually agreed to waive its advisory fee and/or reimburse the Fund's other expenses to the extent that total operating expenses (exclusive of interest, taxes, dividends on short positions, brokerage commissions and other costs incurred in connection with the purchase or sale of portfolio securities) exceed the annual rate of 1.95% of the Fund's average daily net assets attributable to Class R shares and 1.70% of the Fund's average daily net assets attributable to Class I shares. Accordingly, for the year ended May 31, 2006, the Adviser waived $318,096 of its advisory fee and reimbursed the Fund for $1,740 and $1,161 of Class R and Class I expenses, respectively. The Adviser is permitted to recapture fees waived or expenses reimbursed to the extent actual fees and expenses for a period are less than the expense limitation of each class, provided, however, that the Adviser shall only be entitled to recapture such amounts for a period of three years from the end of the fiscal year during which such amount was waived or reimbursed. As of May 31, 2006, the Adviser may in the future recapture from the Fund 24 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- fees waived and expenses reimbursed totaling $940,941 of which $320,997 expires May 31, 2009, $397,695 expires May 31, 2008, and $222,249 expires May 31, 2007. Certain officers of the Trust are also officers of the Adviser.

For the period June 1, 2005 through July 24, 2005, Ultimus was paid $36,283 under the administration agreement. TRANSFER AGENT AND SHAREHOLDER SERVICES AGREEMENT Under the terms of a Transfer Agent and Shareholder Services Agreement between the Trust and DST Systems, Inc. ("DST"), DST maintains the records of each shareholder's account, answers shareholders' inquiries concerning their accounts, processes purchases and redemptions of Fund shares, acts as dividend and distribution disbursing agent and performs other shareholder service functions.

For these services Ultimus received from the Fund a monthly fee at an annual rate of $20 per account, subject to a minimum fee of $1,500 per month for each class of shares.

FUND ACCOUNTING AGREEMENT Prior to July 25, 2005, under the terms of a Fund Accounting Agreement between the Trust and Ultimus, Ultimus calculated the daily net asset value per share and maintained the financial books and records of the Fund. For these services, Ultimus received from the Fund a monthly fee of $3,500, plus an asset based fee equal to .01% of the Fund's average daily net assets up to $500 million and ..005% of such assets in excess of $500 million.

In addition, the Fund reimbursed certain out-of-pocket expenses incurred by Ultimus in obtaining valuations of the Fund's portfolio securities. DISTRIBUTION AGREEMENT The Fund has adopted a plan of distribution pursuant to Rule 12b-1 under the 1940 Act (the "Plan") for Class R shares, which permits Class R to pay for expenses incurred in the distribution and promotion of Class R shares. Under the Plan, Class R may pay compensation to any broker-dealer with whom the Distributor or the Fund, on behalf of Class R shares, has entered into a contract to distribute Class R shares, or to any other qualified financial services firm, for distribution and/or shareholder-related services with respect to shares held or purchased by their respective customers in connection with the purchase of shares attributable to their efforts. The amount of payments under the Plan in any year shall not exceed .25% annually of the average daily net assets allocable to Class R shares. During the year ended May 31, 2006, the Fund paid Class R distribution expenses of $273,965 pursuant to the Plan. Under the terms of a Distribution Agreement between the Trust and SEI Investments Distribution, Co. (the "Distributor"), the Distributor serves as principal underwriter and national distributor for the shares of the Fund. The Fund's shares are sold on a no-load basis and, therefore, the Distributor receives no sales commissions or sales loads for providing services to the Fund. The Distributor is an affiliate of SEI Investments Global Funds Services. Prior to July 25, 2005 Ultimus Fund Distributors, LLC served as the Fund's principal underwriter and distributor. 26 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- 4. CAPITAL SHARE TRANSACTIONS Proceeds and payments on capital shares as shown in the Statement of Changes in Net Assets are the result of the following capital share transactions for the years shown: - -------------------------------------------------------------------------------- YEAR YEAR ENDED ENDED MAY 31, MAY 31, 2006 2005 - -------------------------------------------------------------------------------- CLASS R Shares sold 2,018,023 3,553,278 Shares issued in reinvestment of distributions -- 572,406 Shares redeemed (6,414,977) (11,968,047) ------------ ------------- Net decrease in shares outstanding (4,396,954) (7,842,363) Shares outstanding at beginning of year 11,282,381 19,124,744 ------------ ------------- Shares outstanding at end of year 6,885,427 11,282,381 ============ ============= CLASS I Shares sold 2,334,068 4,445,038 Shares issued in reinvestment of distributions -- 359,150 Shares redeemed (3,379,310) (10,390,377) ------------ ------------- Net decrease in shares outstanding (1,045,242) (5,586,189) Shares outstanding at beginning of year 7,914,256 13,500,445 ------------ ------------- Shares outstanding at end of year 6,869,014 7,914,256 ============ ============= - -------------------------------------------------------------------------------- 5. FOREIGN CURRENCY TRANSLATION Amounts denominated in or expected to settle in foreign currencies are translated to U.S. dollars based on exchange rates on the following basis: A. The market values of investment securities and other assets and liabilities are translated at the closing rate of exchange each day. B. Purchases and sales of investment securities and income and expenses are translated at the rate of exchange prevailing on the respective dates of such transactions. C. The Fund does not isolate that portion of the results of operations caused by changes in foreign exchange rates on investments from those caused by changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gains or losses on investments. Reported net realized foreign exchange gains or losses arise from 1) purchases and sales of foreign currencies, 2) currency gains or losses realized between the trade and settlement dates on securities transactions and 3) the difference between the amounts of 27 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- dividends, interest and foreign withholding taxes recorded on the Fund's books, and the U.S. dollar equivalent of the amounts actually received or paid. Reported net unrealized foreign exchange gains and losses arise from changes in the value of assets and liabilities, other than investment securities, resulting from changes in exchange rates. 6. CONTINGENCIES AND COMMITMENTS The Fund indemnifies the Trust's officers and trustees for certain liabilities that might arise from their performance of their duties to the Fund. Additionally, in the normal course of business the Fund enters into contracts that contain a variety of representations and warranties and which provide general indemnifications. 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. 7. SECURITIES LENDING In order to generate additional income, the Fund may, from time to time, lend its portfolio securities to broker-dealers, banks or institutional borrowers of securities. The Fund must receive 100% collateral in the form of cash or U.S. government securities. This collateral must be valued daily and, should the market value of the loaned securities increase, the borrower must furnish additional collateral to the Fund. During the time portfolio securities are on loan, the borrower pays the Fund any dividends or interest paid on such securities. Loans are subject to termination by the Fund or the borrower at any time. While the Fund does not have the right to vote securities on loan, it has the right to terminate the loan and regain the right to vote if that is considered important with respect to the investment. In the event the borrower defaults in its obligation to the Fund, the Fund bears the risk of delay in the recovery of its portfolio securities and the risk of loss of rights in the collateral. The Fund will only enter into loan arrangements with broker-dealers, banks or other institutions which the Adviser has determined are creditworthy under guidelines established by the Trustees. There were no securities on loan as of May 31, 2006. During the year ended May 31, 2006, the Fund earned $1,778 in securities lending income. 8. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS The Fund enters into forward foreign currency exchange contracts as a way of managing foreign exchange rate risk. The Fund may enter into these contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date as a hedge or cross-hedge against either specific transactions or portfolio positions. The objective of the Fund's foreign currency hedging transactions is to reduce risk that the U.S. dollar value of the Fund's securities denominated in foreign currency will decline in value due to changes in 28 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2006 - -------------------------------------------------------------------------------- foreign currency exchange rates. All foreign currency exchange contracts are "marked-to market" daily at the applicable translation rates resulting in unrealized gains or losses. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. 29 THE ARBITRAGE FUND Report of Independent Registered Public Accounting Firm - -------------------------------------------------------------------------------- TO THE BOARD OF TRUSTEES AND SHAREHOLDERS THE ARBITRAGE FUND We have audited the accompanying statement of assets and liabilities of The Arbitrage Fund (the "Fund"), including the schedules of investments as of May 31, 2006, and the related statement of operations for the year then ended, the statement of changes in 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. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Trust's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of May 31, 2006 by correspondence with the custodian and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of The Arbitrage Fund as of May 31, 2006, 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. TAIT, WELLER & BAKER PHILADELPHIA, PENNSYLVANIA JULY 10, 2006 30 THE ARBITRAGE FUND About Your Fund's Expenses (Unaudited) - -------------------------------------------------------------------------------- We believe it is important for you to understand the impact of costs on your investment. As a shareholder of a mutual fund, you incur two types of costs: (1) transaction costs, including redemption fees; and (2) ongoing costs, including management fees, distribution (12b-1) fees, and other fund expenses. The following examples are 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. A mutual fund's expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the 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 examples below are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. The table on the next page illustrates the Fund's costs in two ways: ACTUAL FUND RETURN - This section helps you to estimate the actual expenses that you paid over the period. The "Ending Account Value" shown is derived from the Fund's actual return, and the third column shows the dollar amount of operating expenses that would have been paid by an investor who started with $1,000 in the Fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, 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 given for the Fund under the heading "Expenses Paid During Period." HYPOTHETICAL 5% RETURN - This section is intended to help you compare the Fund's costs with those of other mutual funds. It assumes that the Fund had an annual return of 5% before expenses during the period shown, but that the expense ratio is unchanged. In this case, because the return used is not the Fund's actual return, the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess the Fund's costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other mutual funds. Note that expenses shown in the table are meant to highlight and help you compare ongoing costs only. The Fund does not charge a front-end sales load. However, a redemption fee of 2% is applied on the sale of shares held within 90 days of the date of purchase and does not apply to the redemption of shares acquired through reinvestment of dividends and other distributions. The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions. More information about the Fund's expenses, including annual expense ratios since inception, can be found in this report. For additional information on operating expenses and other shareholder costs, please refer to the Fund's prospectus. 31 THE ARBITRAGE FUND About Your Fund's Expenses (Unaudited) (Continued) - -------------------------------------------------------------------------------- THE ARBITRAGE FUND - CLASS R - -------------------------------------------------------------------------------- BEGINNING ENDING ACCOUNT VALUE ACCOUNT VALUE EXPENSES PAID DECEMBER 1, 2005 MAY 31, 2006 DURING PERIOD* - -------------------------------------------------------------------------------- Based on Actual Fund Return $1,000.00 $1,051.20 $11.46 Based on Hypothetical 5% Return (before expenses) $1,000.00 $1,013.76 $11.25 - -------------------------------------------------------------------------------- * Expenses are equal to the Arbitrage Fund - Class R annualized expense ratio of 2.24% for the period, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period).

Information regarding how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge upon request by calling toll-free 1-800-295-4485, or on the SEC's website at http://www.sec.gov. The Trust files a complete listing of portfolio holdings for the Fund with the SEC as of the first and third quarters of each fiscal year on Form N-Q. The filings are available upon request, by calling 1-800-295-4485. Furthermore, you may obtain a copy of the filing on the SEC's website at http://www.sec.gov. The Trust's Forms N-Q may also be reviewed and copied at the SEC's Public Reference Room in Washington, D.C., and information on the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330. 33 THE ARBITRAGE FUND Trustees' Renewal Of Advisory Agreement (Unaudited) - -------------------------------------------------------------------------------- The Board of Trustees (the "Board") of The Arbitrage Fund (the "Fund"), including a majority of its independent Trustees, approved the continuance of the Fund's investment advisory agreement with Water Island Capital, LLC, the Fund's investment adviser (hereafter referred to as the "Adviser"). The board determined that continuance of the investment advisory agreement was in the best interests of the Fund and its shareholders. The Board based its decision upon its most recent review of the Adviser's investment personnel, portfolio management process, and performance. The Board discussed the factors below, among others. However, no single factor determined whether the Board approved the continuation of the investment advisory agreement. Rather, it was the totality of the factors that led to the decision. NATURE, EXTENT, AND QUALITY OF SERVICES The Board considered the experience of the personnel managing the Fund's assets as well as the quality of the Fund's investment management over both short- and long-term periods. The Board concluded the Adviser has provided high quality consistent service to the Fund and its shareholders. COST The Board considered the Fund's overall expense ratio, comparing it to other similarly managed mutual funds. In its consideration of the Fund's overall expense ratio, the Board also considered the Adviser's long term commitment to cap operating expenses by waiving a portion of its advisory fee. The Board during its review of costs considered the Fund's advisory fee, comparing the fee to other funds offering similar investment strategies. The Board concluded even though the Fund's overall expense ratio is higher than the average of comparably managed funds, they believe shareholders are receiving a quality investment option for a reasonable price. The Board also concluded that although the advisory fees payable to the Adviser are in the higher range of fees for other comparably managed funds, they believe the fees to be reasonable given the quality of services provided by the Adviser and the complexity of investment strategies implemented by the Adviser. PROFITABILITY OF ADVISER The Board considered the Adviser's profitability with regards to its management of the Fund, concluding that the Adviser's profitability was not excessive and therefore was a secondary factor in connection with the evaluation of advisory fees paid by the Fund. 34 ARBITRAGE FUND Trustees' Renewal Of Advisory Agreement (Unaudited) (Continued) - -------------------------------------------------------------------------------- INVESTMENT PERFORMANCE The Board considered the Fund's short- and long-term performance, including any periods of outperformance or underperformance of relevant benchmarks and peer groups. The Board concluded that the Fund has performed consistent with its investment strategy. The Fund's returns have trailed the average performance of its peer group as well the broad U.S. stock market (as measured by the S&P 500 Index) over the short-term (1 year) while performance when measured over a longer term (4 + years) has exceeded the average performance of its peer group as well the broad U.S. stock market. Information about the Fund's historical performance can be found on page 3 of this Annual Report. ECONOMIES OF SCALE AND ANCILLARY BENEFITS The Board concluded that as a result of the significant decrease in Fund assets over the past year, at the present time it would not be relevant to consider the extent to which economies of scale would be realized as the Fund grows, and whether fee levels reflect potential future economies of scale. The Board also considered the "ancillary benefits" to the Adviser, viewing these as secondary factors in connection with the evaluation of the reasonableness of the advisory fees paid by the Fund. The Board did consider the level of soft dollar activity, concluding that as a result of the Fund being the Adviser's only client, benefits derived from these trades are going directly to the Fund and its shareholders. 35 THE ARBITRAGE FUND Board of Trustees and Officers (Unaudited) - ------------------------------------------------------------------------------------------------------ Overall responsibility for management of the Fund rests with the Board of Trustees. The Trustees serve during the lifetime of the Trust and until its termination, or until death, resignation, retirement or removal.
