Security and Issuer The class of equity security to which this statement on Schedule 13D relates is the Common Stock (the "Securities") of CenturyLink, Inc., a Louisiana corporation (the "Issuer" or the "Company"). The Issuer has its principal executive offices located at 100 CenturyLink Drive, Monroe, Louisiana 71203. 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, Longleaf Partners Small-Cap Fund, and Longleaf Partners Global Fund, series of Longleaf Partners Funds Trust, a registered investment company organized as a Massachusetts business trust and having four series or portfolios. Longleaf Partners Fund, Longleaf Partners Small-Cap Fund, and Longleaf Partners Global Fund may be reached c/o Southeastern Asset Management, Inc., 6410 Poplar Avenue, Suite 900, Memphis, Tennessee 38119. 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 the Longleaf Partners Funds 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 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 the Longleaf Partners Funds, nor Mr. Hawkins has been convicted in any criminal proceeding. (e) During the last five years, neither Southeastern nor the Longleaf Partners Funds, 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; Longleaf Partners Funds Trust, of which the Longleaf Partners Funds are a series, is a Massachusetts business trust. Mr. Hawkins is a citizen of the United States. The names, business addresses, and principal occupations of each director and executive officer of Southeastern, and each Trustee of the Longleaf Partners Funds 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 $1,086,659,813 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. 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 a 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. In this situation Southeastern is switching from a filing on Schedule 13G to 13D as we have more direct conversations with the Company about adding directors to the board. Southeastern believes that the dividend cut was not the best way to address balance sheet concerns, so will seek to add directors who not only bring fiber and network expertise but who also have deep financial expertise. Southeastern believes that the Company's fiber assets are extremely undervalued in the stock market, especially considering the metrics which entities such as infrastructure funds and cable companies have paid in recent private transactions for fiber assets. Therefore Southeastern intends to talk to such infrastructure funds, to cable companies, and to any other verticals who are heavy users of fiber networks but may want to own such networks or parts of them. In light of such private market interest, we believe the preferred way to improve the balance sheet should be through asset sales. Southeastern seeks to add directors who will bring expertise to such discussions. If asset sales are more likely in the intermediate term than the short-term, then Southeastern believes that separate target stocks should be considered for the fiber network business and for the Consumer business. Such target stocks, or tracking stocks, would highlight the value in the two disparate parts of CenturyLink, would provide a path towards eventual actual separation of these segments, and would add capital allocation flexibility for the Company. Southeastern is very supportive of Jeff Storey and his team operationally, and only seeks to affect and improve the Company's capital allocation decision making. We may from time to time and at any time in the future, depending on various factors, take such actions with respect to our investment in the Securities as we deem appropriate at the time including, but are not limited to: (i) acquiring additional Securities and/or other equity, debt, notes, other securities, including but not limited to derivative or other instruments that are based upon or relate to the value of the Securities in the open market, through private transactions or otherwise; (ii) disposing of any or all of the Securities in the open market, through private transactions or otherwise; (iii) entering into agreements or understandings with other shareholders or stakeholders of CenturyLink with respect to the voting, holding and/or disposition of Securities; or (iv) proposing or considering any one or more of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D. To obtain the flexibility to discuss various alternatives, including any of the actions or transactions enumerated in clauses a through j of Item 4 of Schedule 13D, with the Issuer's management or with third parties, Southeastern is converting its ownership filing on Schedule 13G to a filing on Schedule 13D. Item 5. Interest In Securities Of The Issuer (a) The aggregate number and percentage of Securities to which this Schedule 13D relates is 67,403,179 shares of the common stock of the Issuer, constituting approximately 6.2% of the 1,080,659,270 shares outstanding. Common % of outstanding Shares Common Shares Held ___________________________________________________________________ Voting Authority Sole: 23,527,706 2.2% Shared: 40,347,155* 3.7% None: 3,528,318 0.3% Total 67,403,179 6.2% *Consists of shares owned by Longleaf Partners Fund, Longleaf Partners Small-Cap Fund, and Longleaf Partners Global Fund, series of Longleaf Partners Funds Trust, an open-end management investment company registered under the Investment Company Act of 1940, and other advisory clients.

(b) Southeastern generally has the sole power to dispose of or to direct the disposition of the Securities held for discretionary accounts of its investment clients, and may be granted the sole power to vote or direct the vote of such Securities; such powers may be retained by or shared with the respective clients for shared or non-discretionary accounts. Shares held by any Series of Longleaf Partners Funds Trust are reported in the "shared" category. (c) Purchase or sale transactions in the Securities during the past sixty days are disclosed on Schedule II. (d) The investment advisory clients of Southeastern have the sole right to receive and, subject to notice, to withdraw the proceeds from the sale of the Securities, and the sole power to direct the receipt of dividends from any of the Securities held for their respective accounts. Such clients may also terminate the investment advisory agreements without penalty upon appropriate notice. Southeastern does not have an economic interest in any of the Securities reported herein. (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 6 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".
