Production Sharing Contracts regulatory

"has signed, with the Republic of Côte d’Ivoire and PETROCI Holding, Production Sharing Contracts"

Production sharing contracts are agreements between a government and an energy company that define how revenue or physical output from an oil or gas project is divided after production costs are recovered. For investors, they matter because the split, cost recovery rules and fiscal terms determine how much of the project's revenue the company keeps versus what goes to the state — like a recipe that dictates how a cake is baked and who gets which slices.
