Loeb, an individual ("Mr. Loeb" and, together with the Management Company, the "Reporting Persons"). This Amendment No. 1 relates to the Ordinary Common Stock, par value $0.01 per share, of Magellan Health Services, Inc., a Delaware corporation (the "Company"). Unless the context otherwise requires, references herein to the "Common Stock" are to such Ordinary 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, the "Funds"). The Funds directly own the Common Stock to which this Amendment No. 1 relates, and the Reporting Persons 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. Capitalized terms used herein and not otherwise defined have the meanings ascribed thereto in the Schedule 13D. Item 3. Source and Amount of Funds or Other Consideration. Item 3 of the Schedule 13D is hereby amended by deleting the entirety of the text thereof and replacing it with the following: The Funds expended an aggregate of approximately $44,166,429 of their own investment capital to acquire the 2,338,790 shares of Common Stock held by them (the "Shares"). The Shares were acquired in exchange for certain bonds and rights held by the Funds in connection with the Company's reorganization under Chapter 11 of Title 11 of the United States Code. The Funds effect purchases of securities primarily through margin accounts maintained for them with Bear, Stearns Securities Corp. 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. Item 4 of the Schedule 13D is hereby amended by deleting the entirety of the text thereof and replacing it with the following: 4 The purpose of the acquisition of the Shares by the Funds is for investment. The Funds recently acquired 23,790 shares based on a distribution from prior bond holdings with conversion rights to equity. The Reporting Persons may cause the Funds to make further acquisitions of Common Stock from time to time or to dispose of any or all of the shares of Common Stock held by the Funds at any time. The Reporting Persons are engaged in the investment business. In pursuing this business, the Reporting Persons analyze the operations, capital structure and markets of companies, including the Company, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies (often at the invitation of management). From time to time, one or more of the Reporting Persons may hold discussions with third parties or with management of such companies in which the Reporting Person may suggest or take a position with respect to potential changes in the operations, management or capital structure of such companies as a means of enhancing shareholder value. Such suggestions or positions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Exchange Act, including, without limitation, such matters as disposing of or selling all or a portion of the company or acquiring another company or business, changing operating or marketing strategies, adopting or not adopting certain types of anti-takeover measures and restructuring the company's capitalization or dividend policy. Except as set forth above, and in the Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions required to be described in Item 4 of Schedule 13D. Each of the Reporting Persons may, at any time, review or reconsider its position with respect to the Company and formulate plans or proposals with respect to any of such matters, but has no present intention of doing so. Item 5. Interest in Securities of the Issuer. Item 5 of the Schedule 13D is hereby amended by deleting the entirety of the text thereof and replacing it with the following: (a) As of the date of this Amendment No. 1, the Management Company beneficially owns 2,338,790 shares of Common Stock. The Management Company shares voting and dispositive power over such holdings with Mr. Loeb and with the Funds. The Shares represent 8.7% of the approximate total of 26.9 million shares of Common Stock outstanding as reported in the Company's Form 10-Q for the period ended June 30, 2004. None of the individual Funds owns a 5 number of shares of Common Stock equal to or greater than 5% of such total Common Stock outstanding. (b) The Management Company and Mr. Loeb share voting and dispositive power over the 2,338,790 shares of Common Stock held directly by the Funds. (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 sixty days. All of the transactions set forth on Schedule A were effected directly with the Company as part of the Company's reorganization. Except as set forth above, since the filing of the Schedule 13D 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) Not applicable. Item 7. Material to be Filed as Exhibits. 1.
