Robert Talevski, who oversaw $550 million in private equity investments at Telstra Super, left the $11 billion corporate superannuation fund last Thursday.

Hired by Telstra Super in April 2010 from investment consultancy JANA Investment Advisers, Talevski left the fund on Thursday 22 March without serving notice, say people familiar with the matter who requested anonymity.

Brian Jacobs, spokesman for the Melbourne-based fund, confirmed Talevski’s exit but would not explain why he left or say who now manages the fund’s private equity assets. Talevski did not respond to a voicemail message seeking comment.

As portfolio manager of global private markets investments, Talevski was responsible for about $550 million that Telstra Super invested with 19 private equity managers.

Previously, Talevski worked for three years as an investment consultant at JANA, which has provided investment advice to Telstra Super since early 2009.
