The Canada Pension Plan Investment Board (CPPIB) on Wednesday announced changes to its roster of senior executives.

Mining executive Neil Beaumont is joining the pension giant as its senior managing director and chief financial and risk officer. Beaumont, who was most recently vice president finance minerals America at BHP Billiton, succeeds Benita Warmbold. She will retire on Aug. 31.

Additionally, Ed Cass, who was previously senior managing director and chief investment strategist at CPPIB, has been appointed global head of real assets, effective July 15. He replaces Graeme Eadie, who will “continue to work with CPPIB in a general management role with a focus on investment approval processes,” CPPIB says in its announcement.

Geoffrey Rubin will take over from Cass as chief investment strategist. He will also join the CPPIB’s senior management team as senior managing director. Previously, he was managing director, head of portfolio construction and research.

“These appointments demonstrate the deep pool of world-class talent we have at CPPIB, and reflect our succession planning and ability to recruit top talent to support the growth and evolution of the CPP Fund,” says Mark Machin, president and CEO, in a statement.
