"The balancing 30% project equity required for initial Development Costs will be funded by STB. STB will be entitled to recoup 50% of this equity as a preferential payment from 50% of the Project cashflows (subject to ongoing funding requirements of CMSC) that would have otherwise been available to all equity holders"

The way I understand it, 50% of profit goes to STB until 50% of their debt is serviced.
