Oscar Fabian, chief investment officer at VicSuper, is to retire from his full time executive role, effective August 31, 2016.

During his six years at VicSuper, Fabian evolved the investment philosophy and strategy including a major restructure of the investment portfolio into a core (an enhanced passive approach focused on things such as low volatility global equities) and satellite (focused on alpha) model.

He has expanded the team of investment advisers that VicSuper engages with, which a spokesperson for the $16 billion super fund says has led to the investment strategy being both innovative and sophisticated.

For example, environment, social and governance (ESG) factors have been integrated into the investment process to mitigate against long-term risks and take opportunities where appropriate.

Fabian also oversaw the establishment of an investment committee, which makes recommendations to the Trustee on investment policy, strategy and investment activities, as well as the review and monitoring of VicSuper’s investments.

Prior to VicSuper, Fabian was chief investment officer of National Australia Financial Management and then State Superannuation Financial Services (now called StatePlus).

“I would like to thank Oscar for all he’s achieved at VicSuper over the past six years. He has been instrumental in enhancing the fund’s investment model and performance, which is now better placed to deliver consistent, long term returns for our members,” said Michael Dundon, chief executive at VicSuper.

Fabian will be seeking non-executive directorships, as well as spending time farming and looking after his first grandchild who is due shortly.

VicSuper has commenced recruitment for a replacement for Fabian.
