DBRS Releases Report on Cablevision & CSC Holdings, Inc.

Dominion Bond Rating Service (“DBRS”) has today issued a credit rating report covering Cablevision Systems Corporation (“Cablevision” or the “Company”) and its wholly owned financing subsidiary, CSC Holdings, Inc. The report discusses the rating analysis behind DBRS’s recent rating changes which placed these issuers’ ratings “Under Review with Negative Implications”. This action followed the Dolan family’s proposal to privatize its cable business and spin off its media assets under Rainbow Media Holdings LLC.

Today’s report and the June 20, 2005, press release are both available at www.dbrs.com.
