What is an investment decision rule?
When faced with new investments and projects, firms have to decide whether to invest in them or not. The characteristics of a good investment decision rule are:
 First, a good investment decision rule has to maintain a fair balance between allowing a manager analyzing a project to bring in his or her subjective assessments into the decision, and ensuring that different projects are judged consistently. Thus, an investment decision rule that is too mechanical (by not allowing for subjective inputs) or too malleable (where managers can bend the rule to match their biases) is not a good rule.

The cash flows from each year are added to find out the point in time at which the cumulative cash flows equal the initial investment.

Book Rate of Return (BRR): This is a rate of return measure based on accounting earnings and is defined as the ratio of book income to book assets.
