The PPP contract between the Procuring Authority and the Project Company sets out the investment fees at 54% of the gross revenue earned, paid to the Procuring Authority on a quarterly basis. Additionally, the Procuring Authority transferred the collection of the "departure tax" to the Project Company, which is then to be counted as part of the gross revenue to be shared. There was no payment mechanism during the construction phase.

The revenue and financial performance is calculated through quarterly reports submitted by the Project Company. As of the time of the interview for this case study, the annual income for the Procuring Authority was USD $120 million from direct tax and USD $130 million in investment fees.
