Because the selling securityholders may, pursuant to the Prospectus and Prospectus Supplement, offer all or some portion of the Notes they presently hold, no estimate can be given as to the amount of the Notes that will be held by the selling securityholders upon termination of any such sales. In addition, the selling securityholders identified in this Prospectus Supplement or the Prospectus may have sold, transferred or otherwise disposed of all or a portion of their Notes since the date on which they provided the information regarding their Notes, and requested registration thereof, in transactions exempt from the registration requirements of the Securities Act. Accordingly, since certain other selling securityholders may have purchased such Notes and also requested registration thereof, the aggregate amount of Notes listed under the caption “Selling Security Holders” in the Prospectus and Prospectus Supplement may exceed the total amount of Notes issued by the Company. See “Plan of Distribution.”
The Company may from time to time, in accordance with the Registration Rights Agreement, include additional selling securityholders or update the amount of securities held by selling securityholders in future supplements to the Prospectus.
