(Telecompaper) Altice announced an agreement to sell 30 percent of Cablevision to BC Partners and the Canada Pension Plan Investment Board. Altice agreed in September to buy the US cable operator for a total USD 17.7 billion. It will sell the 30 percent stake for USD 1.0 billion to the two partners, who also participated in Altice's takeover of the US cable operator Suddenlink. The shareholders agreement between Altice, BCP and CPPIB for Cablevision is on similar terms to the Suddenlink transaction announced in May, Altice said. The acquisition of Cablevision is expected to close in the first half of 2016, pending regulatory approvals.
