Bethesda Mining In order to decide whether our company should undertake the project‚ we should refer to the project’s NPV and IRR. NPV indicates the possible profit (net cash flow) which the project will yield in future‚ a positive NPV suggests that company can earn profit from the investment and vice versa.
