This positive performance was delivered in the context of strong global merger activity, fueled by strengthening economies in Europe, Asia, and South America. In North America, merger activity in both the U.S. and Canada remains particularly robust, and continues to account for a majority of the deals in which we have invested over the past year. Deal spreads, the return potential associated with each of the transactions in which we invest, have continued to improve over the past 12 months, driven in large part by an uptrend, though slight, in short-term interest rates. Additionally, the large pool of merger transactions announced globally allows us to invest opportunistically in those transactions that offer the best risk-adjusted returns, based on our research. We expect interest rates to remain relatively stable over the months ahead, supported by continued strong growth in the world's major economies. ACCELERATING GLOBAL CONSOLIDATION While most of today's headlines focus on the impact of the large private equity firms and, up until recently, the abundance of inexpensive financing available to finance "going private" transactions, the trends underlying global consolidation among strategic operators are the more important story, in our opinion. The underlying factors that fuel consolidation among strategic operators across the economic spectrum from energy and commodities, to financial, technology and healthcare industries are taking hold in Europe and Asia at an accelerating pace. Legal and regulatory hurdles to cross border mergers continue to ease, accompanied by less nationalistic resistance to foreign buyers from the governments of countries within the European community. Booming economies in China, India, as well as many of the emerging markets are forcing both state-owned and private firms to look beyond their borders to meet their needs for energy, commodities, and building related materials in order to maintain infrastructure growth. We expect these trends to continue, and with it, further consolidation opportunities in the years ahead. We're excited about the opportunities that we're witnessing outside of North America, and expect that the Fund's portfolio will reflect these trends as we invest a greater portion of assets overseas. HOSTILE BIDDING Over the past year we've witnessed an increase in the level of hostile bidding (buyers going directly to shareholders with offers without first reaching agreement with the target's board of directors) taking place in the marketplace. Topping bidders (buyers that offer shareholders a 1 higher price in an attempt to break up an already existing deal between the target and a different buyer) are also showing up with greater frequency as well. We attribute this in part to the competitive aspects of consolidation, as operators within an industry become aggressive bidders to avoid being "left behind" in a marketplace where their competitors are gaining scale. Strategic operators are also moving more aggressively in order to pre-empt the private equity buyers that are ever more present in today's environment, in an attempt to acquire a strategic asset before they fall prey to a leveraged buyout transaction. The upside for arbitrageurs, such as the Arbitrage Fund, is the opportunity to benefit from the potentially greater returns associated with such activity. Thus far in 2007, the Fund has witnessed close to a dozen of the transactions in which we have invested become the subject of higher bids. In many instances, the presence of a hostile bidder will many times force the target company into the hands of a friendly buyer or "white knight". While difficult to predict which targets might attract additional expressions of interest, we expect this trend to continue, fueled in part by the fact that in a global environment, potential bidders can surface from anywhere on the globe. THE ROLE OF PRIVATE EQUITY As mentioned above, the role of the large private equity firms in today's merger environment continues to be significant. With relatively low interest rates and capital markets around the globe receptive to financing these leveraged buyouts, the number and dollar value of transactions involving private equity firms continues to hit record levels. These "going private" transactions have taken place across all industries, from utilities to gaming, from hospitals to semiconductors, and every industry in between. The deals have gotten larger as well. During the past 6 months, we've witnessed ever larger deals involving private equity: Equity Office Properties by Blackstone Group ($36 billion), Clear Channel Communications by Bain Capital and Thomas H. Lee Partners ($27 billion), First Data Corp. and TXU Corp by KKR & Co. ($29 billion and $30 billion respectively), Harrah's Entertainment by Apollo and Texas Pacific Group ($16 billion), and BCE Inc. by Providence Equity ($30 billion), among others. The high level of activity driven by these private equity shops creates opportunities for the Fund to profit. On many occasions, we've witnessed strategic buyers enter into a competitive process with these private buyers to purchase assets. These bidding wars can pay off handsomely for investors. As long as the credit markets remain receptive to financing deals and interest rates remain stable, we expect private equity to play a continued role in consolidation going forward. There are some clouds on the horizon however. The risks associated with private equity deals can be substantial. In those instances where private equity has no existing businesses in the field related to the target, the driving force behind the deal is primarily geared toward generating financial gains through leverage. In the event the target company stumbles or experiences deteriorating fundamentals prior to the deal closing, the private equity buyer may terminate the deal, thus leaving investors with considerable financial downside. Likewise, factors out of the target company's control, such as rising interest rates or difficult credit markets, may prevent the buyer from obtaining the financing necessary to close the transaction. Thus, when investing in a private equity deal, investors generally face elevated risks. The Fund approaches these deals with caution, paying great attention to the level of leverage 2 inherent in the transaction and strategic rationale behind the deal. The returns may appear attractive relative to deals involving strategic buyers, but the risks may not be worth taking. LOOKING AHEAD As we enter the second half of 2007, our outlook remains upbeat. The opportunities for investment across the globe are attractive. Economic growth and the factors driving consolidation across Europe and Asia remain strong. Thus far in 2007, over $2 trillion deals have been announced worldwide, and we expect volumes to remain healthy over the balance of the year.We remain focused on achieving the best risk-adjusted returns available in the marketplacefor our investors, with an emphasis on capital preservation. As always, we appreciate your continued support. Sincerely, /s/ John S. Orrico John S.

See accompanying notes to financial statements. 20 THE ARBITRAGE FUND Notes to the Financial Statements May 31, 2007 - -------------------------------------------------------------------------------- 1. 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 0.25% 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 security's primary trading market is temporarily closed at a time when under normal 21 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- 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 5). 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, 2007, proceeds from redemption fees were $3,514 in Class R and $3,761 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 deferred wash sale losses, deferred post October foreign currency loss and constructive gain from sale of securities. The tax character of dividends and distributions declared during the years ended May 31, 2007 and May 31, 2006 was as follows: - -------------------------------------------------------------------------------- Year Ordinary Long-Term Total Ended Income Capital Gains Distributions - -------------------------------------------------------------------------------- 5/31/07 $6,723,349 $89,346 $6,812,695 5/31/06 -- -- -- - -------------------------------------------------------------------------------- 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. 22 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- 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 Statement 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 agreements. 23 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- Details of swap agreements open at May 31, 2007 are included in the Fund's Portfolio of Investments and Schedule of Securities Sold Short. As of May 31, 2007, the Fund had long and short equity swap contracts outstanding of $3,500,826 and $214,226, 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, 2007: - -------------------------------------------------------------------------------- Cost of portfolio investments (including securities sold short and written options) $146,491,671 ============ Gross unrealized appreciation $ 6,410,733 Gross unrealized depreciation (4,348,693) ------------ Net unrealized appreciation 2,062,040 Net unrealized depreciation on translation of assets and liabilities in foreign currencies (491,355) Undistributed ordinary income 6,350,051 Post October losses (336,519) Post October currency losses (1,357,326) Other temporary differences (1,011,811) ------------ Total distributable earnings $ 5,215,080 ============ - -------------------------------------------------------------------------------- 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, mark-to-market on open forwards, disallowed losses on tax straddles and gains on the constructive sale of securities. For the year ended May 31, 2007, the Fund reclassified net investment losses of $545,293 to accumulated net realized gain (loss) 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 operating loss and reclassification of short sale related dividend expense to capital loss, has no effect on the Fund's net assets or net asset value per share. 24 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- 2. INVESTMENT TRANSACTIONS During the year ended May 31, 2007, 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 $720,165,885 and $655,684,099, respectively. A summary of put and call option contracts written during the year ended May 31, 2007 is as follows: - -------------------------------------------------------------------------------- OPTION OPTION CONTRACTS PREMIUMS - -------------------------------------------------------------------------------- Options outstanding at beginning of year 4,917 $ 663,271 Options written 29,603 5,315,206 Options canceled in a closing purchase transaction (4,382) (556,386) Options exercised (14,434) (3,580,712) Options expired (13,433) (1,670,674) ------------- ------------- Options outstanding at end of year 2,271 $ 170,705 ============= ============= - -------------------------------------------------------------------------------- 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, 2007, the Adviser waived $294,255 of its advisory fee. 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, 2007, the Adviser may in the future recapture from the Fund fees waived and expenses reimbursed totaling $1,012,947 of which $294,255 expires May 31, 2010, $320,997 expires May 31, 2009, and $397,695 expires May 31, 2008. 25 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- Certain officers of the Trust are also officers of the Adviser. Effective October 1, 2004, the Vice President of the Trust also serves as Chief Compliance Officer ("CCO") of the Trust and of the Adviser. The Fund pays the Adviser 15% of the CCO's salary for providing CCO services. ADMINISTRATION AGREEMENT Under the terms of an Administration Agreement, SEI Investments Global Funds Services ("SIGFS") supplies administrative and regulatory services to the Fund, supervises the preparation of tax returns, and coordinates the preparation of reports to shareholders and filings with the Securities and Exchange Commission and state securities authorities. For the performance of these administrative services including fund accounting services, SIGFS receives a monthly fee at an annual rate of 0.10% of the Fund's average daily net assets up to $500 million; and 0.08% of such assets in excess of $500 million, subject to a minimum fee of $150,000 per year. For the year ended May 31, 2007, SIGFS was paid $169,364 under the administration agreement. Certain officers of the Trust are also officers of SIGFS. Such officers are paid no fees by the Trust for serving as officers of the Trust. 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, DST receives from the Fund a monthly complex minimum fee, including two CUSIPs, at an annual rate of $50,000 per year. For each CUSIP thereafter, an additional fee is applied at a minimum fee of $17,500 per CUSIP per year. For the year ended May 31, 2007, DST was paid $106,929 under the transfer agent and shareholder services agreement. 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 0.25% annually of the average daily net assets allocable to Class R shares. During the year ended May 31, 2007, the Fund paid Class R distribution expenses of $203,890 pursuant to the Plan. 26 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- 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. 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, 2007 2006 - -------------------------------------------------------------------------------- CLASS R Shares sold 2,579,669 2,018,023 Shares issued in reinvestment of distributions 251,399 -- Shares redeemed (3,891,401) (6,414,977) ------------ ------------ Net decrease in shares outstanding (1,060,333) (4,396,954) Shares outstanding at beginning of year 6,885,427 11,282,381 ------------ ------------ Shares outstanding at end of year 5,825,094 6,885,427 ============ ============ CLASS I Shares sold 2,093,615 2,334,068 Shares issued in reinvestment of distributions 242,227 -- Shares redeemed (2,149,524) (3,379,310) ------------ ------------ Net increase (decrease) in shares outstanding 186,318 (1,045,242) Shares outstanding at beginning of year 6,869,014 7,914,256 ------------ ------------ Shares outstanding at end of year 7,055,332 6,869,014 ============ ============ - -------------------------------------------------------------------------------- 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. 27 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- 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 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, 2007. 28 THE ARBITRAGE FUND Notes to the Financial Statements (Continued) May 31, 2007 - -------------------------------------------------------------------------------- 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 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. 9. NEW ACCOUNTING PRONOUNCEMENTS On July 13, 2006, the Financial Accounting Standards Board ("FASB") released FASB INTERPRETATION NO. 48, "ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. The Fund will not be required to adopt FIN 48 until November 30, 2007. As of May 31, 2007, the Fund has not evaluated the impact that will result from adopting FIN 48. In September 2006, FASB issued STATEMENT ON FINANCIAL ACCOUNTING STANDARDS ("SFAS") NO. 157, "FAIR VALUE MEASUREMENTS." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of May 31, 2007, the Fund does not believe the adoption of SFAS No. 157 will impact the amounts reported in the financial statements, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements reported on the Statement of Changes in Net Assets for a fiscal period. 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 portfolio of investments as of May 31, 2007, and the related statement of operations for the year then ended, the statements 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. The Trust is not required to have, nor were we 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, 2007 by correspondence with the custodian and brokers or by other appropriate auditing procedures where brokers have not replied to our confirmation requests. 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, 2007, 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 LLP PHILADELPHIA, PENNSYLVANIA JULY 13, 2007 30 THE ARBITRAGE FUND Disclosure of Fund Expenses (Unaudited) - -------------------------------------------------------------------------------- All mutual funds have operating expenses. As a shareholder of a mutual fund, your investment is affected by these ongoing costs, which include (among others) costs for portfolio management, administrative services, and shareholder reports like this one. It is important for you to understand the impact of these costs on your investment returns. Operating expenses such as these are deducted from a mutual fund's gross income and directly reduce its final investment return. These expenses are expressed as a percentage of a mutual fund's average net assets; this percentage is known as a mutual fund's expense ratio. The following examples use the expense ratio and are intended to help you understand the ongoing costs (in dollars) of investing in your Fund and to compare these costs with those of other mutual funds. The examples 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 following page illustrates your Fund's costs in two ways. o ACTUAL FUND RETURN. This section helps you to estimate the actual expenses after fee waivers that your Fund incurred over the period. The "Expenses Paid During Period" column shows the actual dollar expense cost incurred by a $1,000 investment in the Fund, and the "Ending Account Value" number is derived from deducting that expense cost from the Fund's gross investment return. You can use this information, together with the actual amount you invested in the Fund, to estimate the expenses you paid over that period. Simply divide your actual account value by $1,000 to arrive at a ratio (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply that ratio by the number shown for your Fund under "Expenses Paid During Period." o HYPOTHETICAL 5% RETURN. This section helps you compare your Fund's costs with those of other mutual funds. It assumes that the Fund had an annual 5% return before expenses during the year, but that the expense ratio (Column 3) for the period is unchanged. This example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to make this 5% calculation. You can assess your Fund's comparative cost by comparing the hypothetical result for your Fund in the "Expenses Paid During Period" column with those that appear in the same charts in the shareholder reports for other mutual funds. Note: Because the return is set at 5% for comparison purposes -- NOT your Fund's actual return -- the account values shown may not apply to your specific investment. 31 THE ARBITRAGE FUND Disclosure of Fund Expenses (Unaudited) (Continued) - -------------------------------------------------------------------------------- THE ARBITRAGE FUND -- CLASS R - ------------------------------------------------------------------------------------------- BEGINNING ENDING ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE EXPENSE EXPENSES PAID DECEMBER 1, 2006 MAY 31, 2007 RATIOS DURING PERIOD* - ------------------------------------------------------------------------------------------- Based on Actual Fund Return $1,000.00 $1,045.70 2.43% $12.39 Based on Hypothetical 5% Return (before expenses) $1,000.00 $1,012.81 2.43% $12.19 - ------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's Class R annualized expense ratio 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 Fund'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) - -------------------------------------------------------------------------------- On March 27, 2007 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 recognized that the Fund's overall expense ratio is higher than the average of comparably managed funds but concluded 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, the fees are 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. 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's performance warranted continuation of the investment advisory agreement. 34 THE ARBITRAGE FUND Trustees' Renewal of Advisory Agreement (Unaudited) (Continued) - -------------------------------------------------------------------------------- ECONOMIES OF SCALE AND ANCILLARY BENEFITS The Board concluded, given the size of the Fund's assets 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 research derived from these trades was useful 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. The Trustees, in turn, elect the officers of the Fund to actively supervise its day-to-day operations. The officers have been elected for an annual term. The following are the Trustees and executive officers of the Fund: TRUSTEE/ POSITION HELD LENGTH OF EXECUTIVE OFFICER ADDRESS AGE WITH THE TRUST TIME SERVED - ------------------------------------------------------------------------------------------------------------------- *John S.
