It's also interesting that Triway's capex is projected to be the highest in 2017. $116M. Higher than in 2018 ($111) and higher than in 2019 ($94M). (Page 39, 10-Q).
SIAF will receive the bulk of that. Let's make it $100M. Then we can deduce that SIAF's profit from consultancy in 2017 should be close to $30M (or 30%).
That probably has to do with design work, license fees, ground-leveling etc.
