For problem which involve more than a simple "accept or reject" decision, the application of two criteria: 1) The rate of return approach and 2) The present value approach , as they are generally defined, often yield contradictory or ambiguous results. The purpose of this paper is to explore the the reasons for these contradictions or ambiguities and to reformulate this general approach to measuring investment worth so that it always provides a unique and correct basis for decision making.
