This Amendment No. 6 is filed to report changes in the beneficial ownership of shares by David D. Smith, Frederick G. Smith, J. Duncan Smith and Robert E. Smith, each of whom is a member of the group, as defined in the original filing, as amended.

Item 1.	Security and Issuer


Item 2.	Identity and Background


Item 3.	Source and Amount of Funds or Other Consideration


Item 4.	Purpose of Transaction


Item 5.	Interest in Securities of the Issuer

(a - b) The following table sets forth the aggregate number and percentage of shares of Class A common stock and Class B common stock owned individually by each member of the group as of March 22, 2006. Holders of Class B common stock may exchange their shares of Class B common stock into Class A common stock at any time and therefore, each share of Class B common stock represents beneficial ownership of one share of Class A common stock. Except as noted, each person has sole power to vote or direct the vote and to dispose or direct the disposition of all of the shares set forth below and no other person is known to have the right to receive or the pow er to direct the receipt of dividends from, or the proceeds from the sale of, such securities. By virtue of the Stockholders’ Agreement dated April 19, 2005 by and among David D. Smith, Frederick G. Smith, J. Duncan Smith and Robert E. Smith (the “Stockholders’ Agreement”), each member of the group is required to vote all of his Class A and Class B common stock in favor of the other members of the group to cause their election as directors. The Stockholders’ Agreement is substantially similar to the Stockholders’ Agreement dated June 12, 1996 among David D. Smith, Frederick G. Smith, J. Duncan Smith and Robert E. Smith, which expired on July 31, 2005. Consequently, each member may be deemed to beneficially own the shares of common stock individually owned by the other members. Nevertheless, each member of the group disclaims beneficial ownership of the shares owned by the other members of the group.

(1) As of March 16, 2006, there were 38,348,331 shares of Class B common stock outstanding.

(2) The first four rows of this column set forth the percentage of Class A common stock each reporting person would beneficially own if he converted his shares of Class B common stock to Class A common stock and the other reporting persons did not.

As of March 16, 2006, there were 47,321,012 shares of Class A common stock outstanding.

(3) Holders of Class A common stock are entitled to one vote per share and holders of Class B common stock are entitled to ten votes per share except for votes relating to “going private” and certain other transactions. Holders of both classes of common stock will vote together as a single class on all matters presented for a vote, except as otherwise may be required by Maryland law, and holders of Class B common stock may exchange their shares of Class B common stock into Class A common stock at any time. This column sets forth the voting power each reporting person has on the matters on which shares of Class B common stock have ten votes per share, and the voting power the reporting persons as a group have on such matters.

(4) The first four rows of this column set forth the voting power each reporting person would have on matters on which the shares of Class B common stock have ten votes per share if he converted his shares of Class B common stock to Class A common stock and the other reporting persons did not. The last row in this column shows the voting power

the reporting persons as a group would have if they all converted their shares of Class B common stock into shares of Class A common stock.

(5) In addition to his shares of Class B common stock, David D. Smith owns 30,000 shares of Class A common stock directly, 5,840 shares of Class A common stock indirectly through trusts for the benefit of his children, of which he is the custodian, 3,391.8 shares of Class A common stock under the issuer’s 401(k) plan and he may acquire an additional 450,000 shares of Class A common stock upon exercise of options.

Duncan Smith for the benefit of his children of which he is not the trustee. In addition to his shares of Class B common stock, J. Duncan Smith owns 3,188.5 shares of Class A common stock under the issuer’s 401(k) plan.

(8) The shares of Class B common stock include 291,049 shares of Class B common stock held in an irrevocable trust established by Robert E. Smith for the benefit of family members of which he is the trustee but do not include 390,650 shares of Class B common stock held in an irrevocable trust established by Robert E. Smith for the benefit of his children of which he is not the trustee. In addition to his shares of Class B common stock, Robert E. Smith owns 20,000 shares of Class A common stock directly, may acquire 10,000 shares of Class A common stock upon exercise of options and owns 355.8 shares of Class A common stock under the issuer’s 401(k) plan.
