Loral Space & Communications Inc, which holds a majority stake in Canadian satellite communications company Telesat Holdings Inc, has selected private equity firm Apax Partners LLP and two Canadian pension funds to negotiate a sale of Telesat, reports Reuters. The move marks a key step in an auction process for Loral, in which investors who covet control of Telesat need to bring another shareholder, Public Sector Pension Investment Board (PSP), onboard. The three parties chosen by Loral - Apax, the Canada Pension Plan Investment Board and the Ontario Teachers Pension Plan - are now expected to negotiate with PSP about a deal. At stake is a leveraged buyout that could reach US$6 billion to US$7 billion.
