The Fund commenced operations on May 2, 2005. The Fund's investment objective is to seek capital appreciation over the long term by attempting to maximize risk-adjusted returns while minimizing volatility and maintaining a low correlation to the S&P 500 Index. The Fund is a fund of hedge funds that seeks to achieve its objective by deploying its assets primarily among a select group of portfolio managers who over time have produced attractive returns principally in the U.S. equity markets by employing an investing style known as "long/short." This style combines long investments with short sales in the pursuit of opportunities in rising or declining markets. Generally, such portfolio managers conduct their investment programs through unregistered investment vehicles and in other registered investment companies (collectively, the "Investment Funds"), in which the Fund invests as a limited partner, member or shareholder along with other investors. The Fund's Board of Directors (the "Directors") has overall responsibility to manage and control the business affairs of the Fund, including the exclusive authority to oversee and to establish policies regarding the management, conduct and operation of the Fund's business. The Directors have engaged Mellon Hedge Advisors LLC (the "Adviser"), a Delaware limited liability company, to provide investment advice regarding the selection of Investment Funds and to be responsible for the day-to-day management of the Fund. The Adviser is an indirect wholly owned subsidiary of The Bank of New York Mellon Corporation ("BNY Mellon"), and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (the "Advisers Act"). The Adviser has engaged Optima Fund Management LLC (the "Sub-Investment Adviser"), a registered investment adviser under the Advisers Act, to assist it in performing certain of its duties. Interests are offered solely to eligible investment management clients of the Wealth Management Group of BNY Mellon ("Investors") in private placement transactions exempt from registration under the Securities Act of 1933, as amended (the "1933 Act"). Initial and additional applications for interests in the Fund by Investors may be accepted at such times as the Fund may determine and are generally accepted monthly. The Fund reserves the right to reject any application for interests in the Fund. Interests of the Fund are not redeemable. The Fund from time to time may offer to repurchase interests pursuant to written tenders. These repurchases will be made at such times and on such terms as may be determined by the Directors, in their complete and exclusive discretion. The Adviser expects that it will recommend to the Directors that the Fund offer to repurchase interests from Investors twice each calendar year, near mid-year and year-end. Investors can transfer or assign their membership interests only (i) by operation of law pursuant to the death, bankruptcy, insolvency or dissolution of an Investor, or (ii) with the written consent of the Adviser, which may be withheld in its sole and absolute discretion. (2) SIGNIFICANT ACCOUNTING POLICIES: The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. 8 A. VALUATION OF THE FUND AND ITS INVESTMENTS Net asset value of the Fund will be determined by or at the direction of the Adviser as of the close of business at the end of each calendar month and on any other date the Directors may designate in accordance with the valuation principles set forth below or as may be determined from time to time pursuant to policies established by the Directors. The Directors have approved procedures pursuant to which the Fund will value its investments in Investment Funds at fair value. In accordance with these procedures, fair value as of the end of each calendar month and on any other date the Directors may designate and ordinarily will be the value determined as of such period for each Investment Fund in accordance with the Investment Fund's valuation policies and reported at the time of the Fund's valuation. As a general matter, the fair value of the Fund's interest in an Investment Fund will represent the amount that the Fund could reasonably expect to receive from an Investment Fund if the Fund's interest were redeemed at the time of valuation, based on information reasonably available at the time the valuation is made and that the Fund believes to be reliable. All valuations utilize financial information supplied by each Investment Fund and are net of management fees and performance incentive fees or allocations payable to the Investment Funds' managers or pursuant to the Investment Funds' agreements. In the event that an Investment Fund does not report a value to the Fund on a timely basis at the end of each calendar month, the Fund would determine the fair value of such Investment Fund based on the most recent value reported by the Investment Fund, as well any other relevant information available at the time the Fund values its portfolio. Short-term instruments with less than sixty days remaining to maturity are valued at amortized cost, which approximates market value. If the Fund acquires a short-term instrument with more than sixty days remaining to its maturity, it is valued at current market value until the sixtieth day prior to maturity and will then be valued at amortized cost upon the value on such date unless the Board determines during such sixty-day period that amortized cost does not represent fair value. Distributions received or withdrawals from Investment Funds, whether in the form of cash or securities, are first applied as a reduction of the investment's cost. B. SECURITIES TRANSACTIONS AND INCOME Securities transactions are recorded as of the trade date. Interest income is recorded on the accrual basis. Realized gains and losses from Investment Fund transactions are calculated on the identified cost basis. The Investment Funds in which the Fund invests do not regularly distribute income and realized gains from their underlying investment activity. Such undistributed amounts are captured in the value of the Investment Funds in the form of unrealized appreciation. C. FUND COSTS The Adviser bore the non-recurring initial offering and organizational costs of the Fund. The Fund bears all expenses incurred in the ongoing business of the Fund including, but not limited to, the following: all costs and expenses related to portfolio transactions and positions for the Fund's account; legal fees; accounting fees; costs of computing the Fund's net asset value, including valuation services provided by third parties; costs of insurance; a portion, as determined by the Board, of the compensation payable to the Fund's Chief Compliance Officer; certain printing costs; and expenses of meetings of the Board and Investors. 9 MELLON OPTIMA L/S STRATEGY FUND, LLC NOTES TO FINANCIAL STATEMENTS (UNAUDITED) D. INCOME TAXES The Fund is treated as a partnership for Federal income tax purposes. Accordingly, no provision is made by the Fund for Federal or state income taxes. For income tax purposes, each Investor will be treated as a partner of the Fund and, as such, will be taxed upon its distributive share of each item of the Fund's income, gain, loss and deductions allocated to the Fund (including from investments in other partnerships) for each taxable year of the Fund ending with or within the Investor's taxable year. Each item will have the same character to an Investor, and will generally have the same source (either United States or foreign), as though the Investor realized the item directly. Investors must report these items regardless of the extent to which, or whether, the Fund or Investors receive cash distributions for such taxable year, and thus may incur income tax liabilities unrelated to any distributions to or from the Fund. In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. 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. Management has evaluated the implications of FIN 48 and determined that it will not have any impact on the financial statements. The cost of investments for Federal income tax purposes is adjusted for items of accumulated taxable income allocated to the Fund from the Investment Funds. The allocated taxable income is reported to the Fund by the Investment Funds on each calendar year Schedules K-1. The aggregate cost of Investment Funds and the gross unrealized appreciation and depreciation on Investment Funds for federal income tax purposes as of September 30, 2007 are noted below. Federal tax cost of investment funds $ 481,538,482 ---------------- Gross unrealized appreciation 120,536,416 Gross unrealized depreciation -- ---------------- Net unrealized appreciation $ 120,536,416 ================ E. USE OF ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Fund to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Fund believes that the estimates utilized in preparing the Fund's financial statements are reasonable and prudent; however, actual results could differ from these estimates. F. SHORT-TERM INVESTMENTS Short-term investments consist of liquid investments with maturities of less than 90 days. The Fund had $10,902,049 invested in Dreyfus Institutional Preferred Plus Money Market Fund, an affiliated institutional money market fund, including $750,428 of segregated assets, which represents 5% of the estimated value of the June 30, 2007 tender offer. See note 9. 10 MELLON OPTIMA L/S STRATEGY FUND, LLC NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (3) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES: The Adviser provides investment advisory services to the Fund pursuant to an Investment Advisory Agreement. Pursuant to that agreement, the Fund pays the Adviser a monthly fee (the "Investment Advisory Fee") at the annual rate of 1.50% of the Fund's net assets. Pursuant to this agreement the Fund was charged $4,341,580 for the six months ended September 30, 2007. The Fund compensates Mellon Trust of New England, N.A. ("MTNE"), a wholly-owned direct subsidiary of BNY Mellon, under a Custody Agreement to provide custody services for the Fund. In consideration for these services, MTNE earns interest on balances, including disbursement balances and balances arising from purchase and sale transactions, and the Fund reimburses certain of MTNE's expenses. Pursuant to this agreement, the Fund was charged $8,693 for the six months ended September 30, 2007. The Fund has contracted with Mellon Investor Services LLC, a wholly owned subsidiary of BNY Mellon, to provide printing and fulfillment services for the Fund. Pursuant to this agreement, the Fund was charged $8,501 for the six months ended September 30, 2007, which is included in miscellaneous expenses on the Statement of Operations. The Fund reimburses BNY Mellon for a portion of the salary of the Fund's Chief Compliance Officer. Pursuant to this arrangement, the Fund was charged $14,250 for the six months ended September 30, 2007. No other director, officer or employee of Mellon Hedge Advisors, LLC or its affiliates receives any compensation from the Fund for serving as an officer or Director of the Fund. The Fund pays each Director who is not a director, officer or employee of the Adviser or its affiliates (an "Independent Director") an annual retainer and per meeting fees. The Fund also reimburses the Independent Directors for their reasonable out-of-pocket expenses. In addition, the Fund pays the legal fees for the independent counsel of the Independent Directors. The Directors do not receive any pension or retirement benefits from the Fund. (4) INVESTMENT TRANSACTIONS: During the six months ended September 30, 2007, the Fund had aggregate purchases and proceeds from sales of Investment Funds of $22,000,000 and $0, respectively. At September 30, 2007, the Fund had made advance investments of $3,500,000 in Intrepid Capital Fund (QP) and $3,500,000 in Maverick Fund USA, Ltd (5) INDEMNIFICATION: In the ordinary course of business, the Fund may enter into contracts or agreements that contain indemnifications or warranties. Future events could occur that lead to the execution of these provisions against the Fund. Based on its history and experience, management feels that the likelihood of such an event is remote. 11 MELLON OPTIMA L/S STRATEGY FUND, LLC NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (6) FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK: In the normal course of business, the Investment Funds in which the Fund invests trade various financial instruments and enter into various investment activities with off-balance sheet risk. These include, but are not limited to, short selling activities, writing option contracts, contracts for differences, and equity swaps. The Fund's risk of loss in these Investment Funds is limited to the value of these investments as reported by the Fund. (7) RISK FACTORS: An investment in the Fund involves a high degree of risk, including the risk that the entire amount invested may be lost. The Fund allocates assets to a select group of portfolio managers and invests in Investment Funds that invest in and actively trade securities and other financial instruments using a variety of strategies and investment techniques with significant risk characteristics, including the risks arising from the volatility of the equity, fixed income, commodity and currency markets, the risks of borrowings and short sales, the risks arising from leverage associated with trading in the equities, currencies and over-the-counter derivatives markets, the illiquidity of derivative instruments and the risk of loss from counter-party defaults. No guarantee or representation is made that the investment program will be successful. So as to satisfy certain prohibitions on affiliated transactions imposed by the 1940 Act, the Fund may limit its investment position in any one Investment Fund to less than 5% of the Investment Fund's outstanding voting securities. Alternatively, to facilitate investments in Investment Funds deemed attractive by the Adviser, the Fund may purchase non-voting securities of, or waive its right to vote some or all securities in, certain Investment Funds. In cases where the Fund purchases non-voting securities of, or waives its right to vote securities in, an Investment Fund, the Fund will not be able to vote on matters that required the approval of security holders of the Investment Fund, including matters that may be adverse to the Fund's and its Investors' interests. (8) NEW ACCOUNTING REQUIREMENTS: In September 2006, the 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.
