The ''expected net present value'' (ENPV) and ''the expected net present value to expected investment ratio'' are two highly recommended economic parameters for comparing and ranking projects, primarily because these concepts take into account the uncertainty and help in predicting outcomes of program inventories. They are particularly useful as exploration measures and less so for development projects.
