"This will allow us to give comprehensive feedback to all shareholders on the benefits and the risks, and this way our farmers can see if it is something that might suit them in the future," he said.
The pilot was launched earlier this year, giving farmers the opportunity to lock in between 10-75 per cent of their milk supply at the opening season's milk price forecast, which was $7.00 per kg.
Turner said Fonterra recognised that every farming business was different.
While most farmers could live with the market volatility, there were times when some farmers would prefer more certainty, he said.
"It enables farmers to know exactly where they stand with a percentage of their production and this can help with future planning," Turner said. GMP also allowed the co-op to lock in fixed contract prices with its customers.
"This means even if commodity prices drop and the milk price also drops, those customers will continue to pay the fixed price for their products, which supports the GMP price and means there is no risk to the Co-op," he said.
