Security and Issuer The class of equity security to which this statement on Schedule 13D relates is the common stock (the "Securities") of Chesapeake Energy Corporation, a Oklahoma corporation (the "Issuer"). The Issuer has its principal executive offices located at 6100 North Western Avenue, Oklahoma City, Oklahoma 73118. Item 2. Identity and Background Subparagraphs (a), (b), and (c). This statement is being filed by Southeastern Asset Management, Inc. ("Southeastern"), an investment advisor registered with the Securities & Exchange Commission under the Investment Advisers Act of 1940, as amended. The address of its principal office is 6410 Poplar Avenue, Suite 900, Memphis, Tennessee 38119. Southeastern serves as an investment advisor to various individual clients, institutions including qualified retirement plans), endowment funds and to Longleaf Partners Fund, a series of Longleaf Partners Funds Trust, a registered investment company organized as a Massachusetts business trust and having three series or portfolios. The Securities of the Issuer reported in Item 5 herein were acquired on behalf of the investment advisory clients of Southeastern Asset Management, Inc., including Longleaf Partners Fund, under sole or shared discretionary authority granted Southeastern. None of the Securities are owned by or on behalf of Southeastern or by any of its directors or officers, or any Trustees or officers of Longleaf. This statement is also being filed by Mr. O. Mason Hawkins, Chairman of the Board and Chief Executive Officer of Southeastern, in the event he could be deemed to be an indirect beneficial owner of the Securities reported by Southeastern through the exercise of voting control and/or dispositive power over the Securities as the result of his official positions or ownership of voting securities of Southeastern. Neither Southeastern nor Mr. Hawkins owns any Securities for its or his own account and each disclaims beneficial interest in any of the Securities reported herein. (d) During the last five years, neither Southeastern nor Mr. Hawkins has been convicted in any criminal proceeding. (e) During the last five years, neither Southeastern nor Mr. Hawkins has been a party to any civil or administrative proceeding involving any alleged violations of any securities laws. (f) Southeastern is a corporation organized and existing under the laws of the State of Tennessee. Mr. Hawkins is a citizen of the United States. The names, business addresses, and principal occupations of each director and executive officer of Southeastern are set forth in Schedule I. Item 3. Source and Amount of Funds or Other Consideration The respective investment advisory clients of Southeastern used approximately $2,291,531,554 in the aggregate to purchase the Securities reported in this filing. All assets used to purchase Securities were assets of these respective clients and none were assets of Southeastern. In addition, none of the proceeds used to purchase the Securities were provided through borrowings of any nature. Item 4. Purpose of Transaction The Securities reported in this filing have been purchased and held for investment purposes on behalf of client accounts over which Southeastern has either sole or shared discretionary investment or voting power. The Securities are reported by Southeastern and by Mr. O. Mason Hawkins, Chairman of the Board and Chief Executive Officer in the event that either should be deemed to be a member of a group under Section 13(d)(3) or the beneficial owner of these Securities under the provisions of subparagraph (b)of Rule 13d-3 under the Securities Exchange Act of 1934. Beneficial ownership on the part of Southeastern and Mr. Hawkins as members of a group or as beneficial owners is expressly disclaimed, as permitted by Rule 13d-4. All purchases of Securities were made for investment purposes only, in the ordinary course of business of Southeastern as a registered investment advisor. Southeastern may purchase additional Securities on behalf of clients in the future, or may sell all or a part of the current holdings of the Securities. Southeastern is engaged in the business of investment management of its clients' assets and pursues an investment philosophy of identifying undervalued situations and acquiring positions in undervalued companies on behalf of its clients. In pursuing this investment philosophy, Southeastern analyzes the operations, capital structure and markets of companies in which its clients invest and continuously monitors the business operations of such companies through analysis of financial statements and other public documents, through discussions with knowledgeable industry observers, and with management of such companies, often at management's invitation. Southeastern qualifies as an institution which may elect to file securities ownership reports required by the Securities Exchange Act of 1934 on Schedule 13G and, as a routine matter, Southeastern utilizes Schedule 13G for its reporting of the ownership positions held by its investment advisory clients. As the result of investment analysis or the occurrence of events, Southeastern may desire to participate in discussions with the particular portfolio company's management or with third parties about significant matters in which Southeastern may suggest possible courses of action to assist in building corporate intrinsic value per share or to cause the Company's true economic value to be recognized. In such situations, Southeastern may elect to convert a filing on Schedule 13G to a filing on Schedule 13D in order to be more active in corporate governance and management matters, and to have the ability to enter into discussions with third parties concerning proposed corporate transactions of a significant nature. To obtain the flexibility to discuss all options, including but not limited to any of the actions or transactions enumerated in clauses a through j of Item 4 of Schedule 13D, with the Issuer's management, Board of Directors and/or with third parties, Southeastern is hereby converting its ownership filing on Schedule 13G to a filing on Schedule 13D. Southeastern intends to discuss with management, the Board, as well as various third parties opportunities to maximize the value of the company for all shareholders. Item 5.

(e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer The powers of disposition with respect to Securities owned by discretionary private accounts of Southeastern are established in written investment advisory agreements between clients and Southeastern, which are entered into in the normal and usual course of the business of Southeastern as a registered investment advisor and which are generally applicable to all securities purchased for the benefit of each such discretionary private account. There are no special or different agreements relating to the Securities of the Issuer. The written investment advisory agreements with clients generally do not contain provisions relating to borrowing of funds to finance the acquisition of the Securities, acquisition of control, transfer of securities, joint ventures, or any of the other transactions listed in the instructions to Item 7 of Schedule 13D other than voting of proxies. In connection with voting, Southeastern may be allowed or directed to vote the proxies received by accounts classified as "discretionary" or "shared" accounts; such authority is generally retained by the clients for accounts classified as "non-discretionary".
