Loeb, an individual ("Mr. Loeb", and together with the Management Company and the Offshore Fund, the "Reporting Persons"). This Amendment No. 1 relates to the Common Stock, par value $0.001 per share, of Acorda Therapeutics, Inc., a Delaware corporation (the "Company"). Unless the context otherwise requires, references herein to the "Common Stock" are to such Common Stock of the Company. The Management Company is the investment manager or adviser to a variety of hedge funds and managed accounts (such funds and accounts, collectively, including but not limited to Offshore Fund, the "Funds"). The Funds directly own the Common Stock to which this Schedule 13D relates, and the Management Company and Mr. Loeb may be deemed to have beneficial ownership over such Common Stock by virtue of the authority granted to them by the Funds to vote and to dispose of the securities held by the Funds, including the Common Stock. Item 3. Source and Amount of Funds or Other Consideration. Item 3 of the Schedule 13D is hereby amended and restated as follows: The Funds expended an aggregate of approximately $12,281,278 of their own investment capital to acquire the 1,000,000 shares of Common Stock held by them. Offshore Fund expended an aggregate of approximately $7,966,978 of its own investment capital to acquire its 661,400 shares of Common Stock. The Funds effect purchases of securities primarily through margin accounts maintained for them with Bear, Stearns Securities Corp. and Goldman, Sachs & Co., which may extend margin credit to the Funds as and when required to open or carry positions in the margin accounts, subject to applicable Federal margin regulations, stock exchange rules and the firm's credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts. Item 4. Purpose of Transaction. The Reporting Persons have reduced their beneficial ownership of the Common Stock, while still maintaining substantial beneficial ownership, in order to reallocate capital to other investment opportunities within the biotechnology industry. 5 Item 5. Interest in Securities of the Issuer. Item 5 of the Schedule 13D is hereby amended and restated as follows: (a) As of the date of this Schedule 13D, the Management Company beneficially owns 1,000,000 shares of Common Stock (the "Shares"). The Shares represent 4.1% of the 24,126,972 shares of Common Stock outstanding as of April 30, 2007, as reported in the Company's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2007. The percentages used herein and in the rest of this statement are calculated based upon this number of outstanding shares. As of the date of this Schedule 13D, the Offshore Fund directly beneficially owns 661,400 shares of Common Stock, which represent 2.7% of the outstanding shares of Common Stock. None of the other individual Funds owns a number of shares of Common Stock representing more than 5% of such total. (b) The Management Company and Mr. Loeb share voting and dispositive power over the 1,000,000 shares of Common Stock held directly by the Funds. The Management Company, Mr. Loeb and Offshore Fund share voting power and dispositive power over the 661,400 shares of Common Stock held by Offshore Fund. (c) Schedule A hereto sets forth certain information with respect to transactions by the Funds, at the direction of the Reporting Persons, in the Common Stock during the past 60 days. Schedule B hereto sets forth certain information with respect to transactions by the Offshore Fund, at the direction of the Management Company and Mr. Loeb, in the Common Stock during the past 60 days. All of the transactions set forth on Schedule A and Schedule B were effected in the NASDAQ Global Market. Except as set forth on Schedule A and Schedule B, during the last 60 days there were no transactions in the Common Stock effected by the Reporting Persons, nor, to the best of their knowledge, any of their directors, executive officers, general partners or members. (d) Other than the Funds which directly hold the Shares, and except as set forth in this Item 5, no person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares. (e) Each of the Reporting Persons ceased to be the beneficial owner of more than five percent of the total outstanding Common Stock on May 22, 2007.
