"Fonterra remains in a strong financial position and any damages award will not affect our ability to operate. We will share further details with the market, our farmers and staff as soon as practical," he said.
Fonterra, in August 2013, said products used in infant formula and sports drinks might contain botulism. The news made headlines around the world but it later turned out to be a false alarm.
In the aftermath, Danone cancelled supply agreements with Fonterra and launched a $1 billion lawsuit against the dairy co-op.
Danone alleged Fonterra breached the Fair Trading Act and wanted damages expected to exceed €630 million.
But that High Court action was deferred at Fonterra's request so arbitration in Singapore could occur first.
Arbitration is similar to a civil court contest, but its confidential nature is attractive to parties that don't want a dispute aired in public.
In Fonterra's last annual report, the company said: "Uncertainty exists regarding the outcome of the proceedings. Fonterra has provided $11 million in respect of the Danone claims, which represents the maximum contractual liability to Danone."
Fonterra's units last traded on the NZX at $6.36 per unit, having gained 45c or 7.6 per cent over the last 12 months.
