NZX director Neil Paviour-Smith told the High Court the company spent no more than A$10 million on developing the Clear Grain Exchange but rejected former owner Ralec's claims that amounted to just one-tenth of what it had promised to invest.
Paviour-Smith, who is also managing director of brokerage Forsyth Barr, is the first witness to be called before the hearing, which is expected to last another eight weeks. He began giving evidence on Friday and will be the only NZX director to appear, although former chairman Andrew Harmos and former chief executive Mark Weldon are scheduled to give evidence in the coming weeks.
NZX claims Clear's former owners, Grant Thomas and Dominic Pym, and their companies Ralec Commodities and Ralec Interactive, misled NZX with "wildly inaccurate" forecasts when it bought Australian Clear Grain Exchange, a commodities trading platform, in October 2009.
Ralec subsequently counterclaimed. It claims NZX, which bought the platform for A$7 million ($7.5 million) with the potential for a further A$14 million of earnouts, failed to fund the exchange sufficiently.
NZX is suing for between A$20.7 million and A$37.6 million, and Ralec has countered with a suit totalling A$14 million plus bonuses.
