(1)	Our registration of these securities does not necessarily mean that the selling securityholders will sell any or all of the securities. The total principal amount of notes and shares of common stock issuable upon exchange of notes listed in the table may be more than $252,695,000 and 8,095,842 shares, respectively, because certain of the selling securityholders may have sold, transferred or otherwise disposed of all or a portion of their notes in transactions exempt from the registration requirements of the Securities Act since the date on which they provided information regarding their notes for inclusion in this table. The maximum principal amount of notes and number of shares of common stock issuable upon exchange of the notes that may be sold under this prospectus will not exceed $252,695,000 and 8,095,842 shares, respectively.
(2)	Figures in this column assume that the selling securityholder will fully exchange the notes for shares of Holdings’ class B common stock held by them.
(3)	Pursuant to the terms of the indenture governing the terms of the notes, no fractional shares will be issued upon exchange. Instead of fractional shares, the holders of the notes will receive cash in an amount equal to the same fraction of the closing sale price of the class B common stock as set forth on the New York Stock Exchange on the business day preceding the day the notes are exchanged into shares of class B common stock. Therefore, the total sum of shares listed in this column are less than the total shares of class B common stock being registered pursuant to the registration statement of which this prospectus is a part.
(4)	Figures in this column do not include the shares of class B common stock issuable upon exchange of the notes listed in the column to the right.
(5)	This selling securityholder is an affiliate of a registered broker-dealer and has advised us that it purchased the notes in the ordinary course of business and, at the time of the purchase of the notes, had no agreements or understandings directly or indirectly with any person to distribute the notes or the underlying shares of class B common stock.
