In financial theory, if there is a choice between two mutually exclusive alternatives, the one yielding the higher NPV should be selected. A positive net present value indicates that the projected earnings generated by a project or investment (in present dollars) exceeds the anticipated costs (also in present dollars).
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
When NPV demonstrates a positive value, it indicates that the project is expected to generate value. Conversely, if NPV shows a negative value, the project is expected to lose value. In essence, IRR signifies the rate of return attained when the NPV of the project reaches a neutral state, precisely at the point where NPV breaks even. [4]

Like the internal rate of return, the modified internal rate of return is not valid for ranking projects of different sizes, because a larger project with a smaller modified internal rate of return may have a higher net present value. However, there exist variants of the modified internal rate of return which can be used for such comparisons ...
Determination of the after-tax NPV of the investment; Calculation of the after-tax NPV of the operating cost stream; Applying a sinking fund amortization factor to the after-tax amount of any salvage value. In mathematical notation, for assets subject to the general half-year rule of CCA calculation, this is expressed as:
Calculating the net present value, , of a stream of cash flows consists of discounting each cash flow to the present, using the present value factor and the appropriate number of compounding periods, and combining these values. [1]
A risk premium can also be attached to the hurdle rate if management feels that specific opportunities inherently contain more risk than others that could be pursued with the same resources. A common method for evaluating a hurdle rate is to apply the discounted cash flow method to the project, which is used in net present value models. The ...
