Last month, Fonterra cut its farmgate milk price forecast for the current season to $4.70 per kg of milk solids - down from previous forecast of $5.30 a kg - due to sharply lower market prices.
Combined with the previously announced estimated dividend range of 25-35 cents per share, Fonterra's cash payout is forecast at $4.95 to $5.05 a kg for 2014/15.
Fonterra's thinking centres on wholemilk prices recovering to their long-run average of around US$3500 a tonne.
Falling oil prices, geopolitical uncertainty in Russia and Ukraine, and subdued demand from China have all contributed to sharply weaker prices since the start of last year.
