CUSIP NO. 38911N107 SCHEDULE 13D Page 6 of 17 Pages Item 1. Security and Issuer. This statement relates to American Depository Shares ("ADSs") representing shares of common stock, par value Won 500 per share (the "Common Stock"), of Gravity Co., Ltd., a corporation organized under the laws of the Republic of Korea ("Gravity"). Each ADS represents one-fourth of one share of Common Stock. Gravity's principal executive office is located at 14th Floor, Meritz Tower, 825-2 Yeoksam-Dong, Gangnam-Gu, Seoul, 135-934, Korea. Item 2. Identity and Background. This statement is being filed by: (i) Moon Capital Master Fund Ltd., a Cayman Islands exempted company (the "Master Fund"), with respect to ADSs directly owned by it; (ii) Moon Capital Management LP, a Delaware limited partnership (the "Investment Manager"), which serves as the investment manager of the Master Fund, with respect to ADSs directly owned by the Master Fund; (iii) JWM Capital LLC, a Delaware limited liability company (the "IMGP"), which serves as the general partner of the Investment Manager, with respect to ADSs directly owned by the Master Fund; (iv) Mr. John W. Moon ("Mr. Moon"), who serves as the managing member of the IMGP with respect to ADSs directly owned by the Master Fund. The Master Fund, the Investment Manager, the IMGP and Mr. Moon are hereinafter sometimes collectively referred to as the "Reporting Persons". Any disclosures made herein with respect to persons or entities other than the Reporting Persons are made on information and belief. By virtue of the communications among the Reporting Persons and representatives of Ramius Capital Group, LLC and certain of its affiliates (collectively the "Ramius Entities") as to the matters more fully described in Item 4 and the Sharing Agreement, dated as of March 28, 2006, between the Reporting Persons and the Ramius Entities as to the sharing of certain information and expenses attached as an exhibit to this Schedule 13D, the Reporting Persons may be deemed to be a "group" with the Ramius Entities for purposes of the Securities Exchange Act of 1934, as amended (the "Act"). Although the Reporting Persons do not affirm that such a group has been formed, this disclosure is being made to ensure compliance with the Act. On the basis of information provided to the Reporting Persons by the Ramius Entities, the Reporting Persons believe that the Ramius Entities are the beneficial owners of an aggregate of 1,756,372 ADSs representing approximately 6.3% of the outstanding shares of Common Stock. The Reporting Persons expressly disclaim beneficial ownership of securities held by any person or entity other than the various accounts under the Reporting Persons' management and control. The securities reported herein as being beneficially owned by the Reporting Persons do not include any CUSIP NO. 38911N107 SCHEDULE 13D Page 7 of 17 Pages securities held by the Ramius Entities (including but not limited to accounts or entities under its control) or any other person or entity other than the various entities and accounts under the Reporting Persons' management and control. The address of the business office of each of the Reporting Persons is 499 Park Avenue, 8th Floor, New York, NY 10022. Each of the Investment Manager and the IMGP is organized under the laws of the State of Delaware. The Master Fund is organized under the laws of the Cayman Islands. Mr. Moon is a citizen of the United States of America. The name, business address and present principal occupation or employment (including the name and address of the corporation or organization in which such employment is conducted) of each executive officer and director of the Master Fund and Moon Capital Global Equity Offshore Fund Ltd., a Cayman Islands limited company and the controlling person of the Master Fund (the "Offshore Fund"), is set forth in Schedule A to this statement and is incorporated herein by reference in its entirety. To the undersigned's knowledge, all such persons are citizens of the United States unless otherwise noted in Schedule A. During the last five years, none of the Reporting Persons nor, to undersigned's knowledge, the Offshore Fund or any of Master Fund's or Offshore Fund's executive officers or directors has (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration. All of the funds used to purchase the ADSs described in this Schedule 13D came from investment funds under management of the Investment Manager. Item 4. Purpose of Transaction. The Reporting Persons purchased their ADSs based on their belief that the Common Stock underlying the ADSs at the time of purchase were substantially undervalued and represented an attractive investment opportunity. The Reporting Persons originally acquired their Gravity securities for investment purposes in the ordinary course of business, and have previously reported their ownership of ADSs on Schedule 13G. The Reporting Persons are filing this Schedule 13D to reflect the formation of the Committee (as defined below) with the other members of the Committee and to reflect the Committee's intention to take certain actions as described in this Item 4. The Reporting Persons and the Ramius Entities have formed The Gravity Committee for Fair Treatment of Minority Shareholders (the "Committee") to protect the rights of minority shareholders of Gravity (Nasdaq: GRVY) and to maximize the value of the Common Stock. The Committee believes that Gravity's Board of Directors (the "Gravity Board") CUSIP NO. 38911N107 SCHEDULE 13D Page 8 of 17 Pages approved transactions that may have benefited Taizo Son and other entities affiliated with Taizo Son or SOFTBANK Corp. ("SOFTBANK"), including GungHo Online Entertainment ("GungHo") (JP: 3765), to the potential detriment of Gravity's minority shareholders. Based on public filings, the Committee believes that Taizo Son beneficially owns approximately 52.4% of Gravity's Common Stock. In addition, based on public filings, the Committee believes that Taizo Son owns approximately 82% of Asian Groove, Inc., which owns approximately 32% of GungHo, and that SOFTBANK owns approximately 45% of GungHo. SOFTBANK's President, Masayoshi Son, is Taizo Son's brother. In August 2005, according to public filings, an affiliate of Taizo Son, with financing facilitated by Masayoshi Son or his affiliates, purchased a 52.4% interest in Gravity from Mr. Jung Ryool Kim, Gravity's founder, and certain members of his family (the "Controlling Purchase"). The purchase price of $24.70 per ADS represented a premium of over three times the then current share price. According to GungHo's 2005 financial statements, substantially all of GungHo's revenue was derived from products licensed from or sold and licensed to Gravity with 82% of the revenue generated by the license from Gravity of the popular online game Ragnarok, which license expires in August 2006. The Committee believes that the $24.70 per ADS price paid by the Taizo Son affiliate in the Controlling Purchase indicates that Ragnarok, among other things, is extremely important to GungHo's business. The Committee also believes that changes in the Gravity Board and management since the completion of the Controlling Purchase may have been effected to protect GungHo's interests, to the potential detriment of Gravity's minority shareholders. The Committee intends to examine, among other things, potential conflicts of interest among members of the Gravity Board, several related party transactions entered into between Gravity and entities affiliated with Taizo Son or SOFTBANK, and the potential for future conflicts of interest in transactions between Gravity and entities affiliated with Taizo Son or SOFTBANK. In particular, the Committee believes that Taizo Son and the Gravity Board may have conflicts of interest and may not seek to maximize value for all Gravity shareholders in upcoming negotiations for a renewal of the license for Ragnarok, Gravity's main revenue driver. GungHo's license of Ragnarok expires in August 2006. The Committee is also concerned that the Gravity Board may not authorize management to solicit alternative bidders for the Ragnarok license to create maximum value for Gravity shareholders. In order to maximize the value of Gravity's Common Stock and in order to protect the rights of minority shareholders, the Committee, among other things, may: o Hold discussions with holders of Common Stock in Korea, with the possible future inclusion of these holders in the Committee; o Consider converting all or a portion of their ADSs into Common Stock; o Seek to nominate independent members to the Gravity Board, potentially at a special Extraordinary General Meeting of Shareholders to monitor Gravity's negotiations of the Ragnarok license and to establish and oversee an auction CUSIP NO. 38911N107 SCHEDULE 13D Page 9 of 17 Pages process to determine whether alternative parties might offer terms superior to those offered by GungHo; o Seek to negotiate with Taizo Son a resolution whereby Taizo Son or one of his affiliates offers to acquire all the Common Stock held by the minority shareholders; and/or o If necessary, commence litigation against Gravity, its management and/or the Gravity Board in Japan, Korea and/or in the United States. In the event that entities affiliated with Taizo Son or SOFTBANK offer to buy the Common Stock of the minority shareholders, the Committee intends to only entertain a proposal that offers fair value and is made available to all Gravity minority shareholders. The Committee notes that, according to public filings, an affiliate of Taizo Son, with financing facilitated by Masayoshi Son or his affiliates, paid $24.70 per ADS in the Controlling Purchase. The Committee believes that Gravity's prospects are strong and that Gravity has significant potential for additional licensing revenues from games not yet released, including, among others, Requiem and Ragnarok 2. The Committee has retained Hannuri Partners as legal counsel in Korea. Certain members of the Committee have retained Schulte Roth & Zabel LLP and Chadbourne & Parke LLP as legal counsel in the United States. Certain members of the Committee entered into the Sharing Agreement, as more fully described in Item 6. The Reporting Persons may, alone or with others, communicate with or pursue discussions with Gravity, and with other shareholders and other third parties, with respect to the matters described above and potentially with respect to other matters of concern with respect to the Reporting Persons' investment in the ADSs. Except to the extent set forth above, or in any other Item hereof, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the matters set forth in Item 4 of Schedule 13D. However, the Reporting Persons may, at any time and from time to time, review or reconsider their position with respect to Gravity, and formulate (and modify) plans or proposals with respect to any such matters. The Reporting Persons intend to review their investment in Gravity on a continuing basis and may engage in discussions with management, the Gravity Board, other shareholders of Gravity and other relevant parties concerning the business, operations, board composition, management, strategy and future plans of Gravity. Depending on various factors including, without limitation, Gravity's financial position and strategic direction, the outcome of the discussions and actions referenced in this Item 4, actions taken by the Gravity Board, the price levels of the ADSs and/or the Common Stock, availability of funds, subsequent developments affecting Gravity, Gravity's business, other investment and business opportunities available to the Reporting Persons, conditions in the securities market, general economic and industry conditions and other factors that the Reporting Persons may deem relevant from time to time, the Reporting Persons may maintain their investment at current levels or may in the future take such actions with respect to their investment in Gravity as they deem appropriate CUSIP NO. 38911N107 SCHEDULE 13D Page 10 of 17 Pages including, without limitation, purchasing additional ADSs and/or shares of Common Stock or selling some or all of their ADSs and/or shares of Common Stock, engaging in short selling of or any hedging or similar transactions with respect to the ADS and/or Common Stock, or changing their intention with respect to any and all matters referred to in this Item 4. Any acquisition or disposition of ADSs and/or shares of Common Stock, or short sale or other hedging transaction with respect to the ADSs and/or shares of Common Stock, by the Reporting Persons may be effected through open market or privately negotiated transactions, or otherwise.
