This Schedule 13D relates to the common stock, par value $0.01 per share, of Saga Communications, a Delaware corporation (the "Issuer"). Unless the context otherwise requires, references herein to "Securities" or "Shares" are to such common stock of the Issuer. Item 1. Security and Issuer. This statement on Schedule 13D relates to the Common Stock of the Company, and is being filed pursuant to Rules 13d?1 and 13d?5 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The address of the principal executive offices of the Issuer is 73 Kercheval Avenue, Grosse Pointe Farms, Michigan 48236. Item 2. Identity and Background. (a) Avenir is an investment advisor registered with the Securities & Exchange Commission under the Investment Advisers Act of 1940, as amended. Avenir is a Virginia Corporation. (b) The address of the principal business and principal office of Avenir is 1725 K St NW, Suite 401, Washington DC, 20006. (c) The principal business of Avenir is to serve as an investment manager to various clients, institutions (including qualified retirement plans), and endowment funds. (d) During the last five years, Avenir has not been convicted in a criminal proceeding (e) During the last five years, Avenir has not been a party to any civil or administrative proceeding involving any alleged violations of any securities law. (f) United States Item 3. Source and Amount of Funds or Other Consideration. The Securities of the Issuer were primarily acquired on behalf of the investment advisory clients of Avenir under sole or shared discretionary authority granted Avenir. In addition, Avenir and/or its principal officers and employees purchased Shares in the Issuer for their personal accounts. The aggregate amount of funds used to purchase the Securities reported in this filing totaled approximately $19,296,637. In addition, none of the proceeds used to purchase the Securities were expressly provided through borrowings, though certain accounts managed by Avenir may carry margin balances from time to time. 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 Avenir has sole discretionary investment or voting power, as well as on behalf of accounts of Avenir and the employees of Avenir. All purchases of Securities were made for investment purposes only, in the ordinary course of business of Avenir as a registered investment advisor. Avenir may purchase additional Securities on behalf of clients and its own employees in the future, or may sell all or a part of the current holdings of the Securities. Avenir 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, Avenir 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. SCHEDULE 13D ------------------ ------------------ CUSIP No. 786598102 Page 4 of 6 Pages ------------------ ------------------ Avenir 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, Avenir 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, Avenir may desire to participate in discussions with the particular portfolio company's management or with third parties about significant matters in which Avenir 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, Avenir may elect to file Schedule 13D, or to convert an existing 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 necessary flexibility to discuss any such actions or transactions with any such third parties or with the Issuer's management, Avenir is filing Schedule 13D. Avenir will thus be able to discuss any such proposals with the respective third parties and/or with management of the Issuer as a means of fulfilling its fiduciary duties to its clients. As the result of this filing on Schedule 13D, and depending on the circumstances, Avenir and its clients could support one or more of the actions or transactions described in clauses (a) through (j) of Item 4 of the Schedule 13D form. Item 5. Interest In Securities Of The Issuer (a) The aggregate number and percentage of Securities to which this Schedule 13D relates is 1,440,322 shares of the common stock of the Issuer, constituting approximately 7.96% of the 18,098,028 shares outstanding. (b) Avenir 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, for which Avenir generally makes recommendations with respect thereto. (c) All purchase or sale transactions in the Securities during the past sixty days are set forth on Schedule I. (d) The investment advisory clients of Avenir 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. (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 Avenir are established in written investment advisory agreements between clients and Avenir, which are entered into in the normal and usual course of the business of Avenir 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 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, Avenir 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".
