Platinum Asset Management's investment team has banked the rewards of a market-beating turn, extracting an additional $15 million in pay from the homegrown international fund manager.

Staff remuneration expenses surged 43.8 per cent to $49.2 million over 2017-18, which Platinum said was fair in light of "excellent" returns and recognition for outperformance delivered for the 12 and 36 months ruled off March 31. Most of it went to the business's investment team; Platinum has 98 staff, 31 of which are involved in stockpicking, and it manages more than $25 billion.
