Canada's Potash Corp of Saskatchewan , the  world's largest fertilizer producer, is sizing up its chances of gaining control  of the four other fertilizer companies in which it holds minority stakes, Chief  Executive Officer Jochen Tilk said on Wednesday.
Saskatoon,  Saskatchewan-based Potash Corp is reviewing its $4.5-billion worth of minority  stakes in China's Sinofert Holdings Ltd, Israel Chemicals, Jordan's Arab Potash  Co PLC and Chile's SQM.
"The strategic objective is to obtain some  control or participation in the companies," Tilk, who took over as CEO five  months ago, said at a Citi investor conference in New York. "We see them as  opportunities, but we're also mindful that we can't be (in) minority investments  forever unless we have a plan going forward."
The company has long said  it wants majority stakes, but is now conducting a formal review of the  investments. Tilk said he is content with the influence Potash holds at Arab  Potash and Sinofert.
No decisions have been made, and Potash Corp would  not take any action without consulting the companies involved, Tilk  said.
It tried to buy control of Israel Chemicals under previous CEO Bill  Doyle, but was rebuffed in 2013 by the Israeli government, which holds a golden  share in the company.
