Infratil hit a record $5.26 and ended the day up 3.5 per cent at $5.20 on a volume of 655,000 shares, in line with its 90-day average of 661,000. The infrastructure investment firm said the independent valuation of its 48 percent stake in CDC Data Centres rose by as much as $700 million in the latest year, which meant manager Morrison & Co would receive a bigger incentive fee.
Goodson said it was a double-edged sword for Infratil investors, because while the increased valuation was backed by strong future cash flow, it crystallised the performance fee for the manager.
