Class B include items which low demanded and have smaller effect than class A. Lastly, class C has least effects on inventory value, high value and rarely ordered, so that firm store small amount of class C because of high cost.
Firm usually apply this method bases on Pareto principal, which is called 80/20 rule. This means most of firm realizes that 80 percentages of their revenue come from their top 20 percentage total items which is presented as class A. Hence, firm can set optimal ratio between classes. A typical ratio is 70/20/10 for class A/B/C.

For example, if account receivable cannot be collected on time, firm need precautionary cash to pay for their operating cost. In addition, with problems with inventory such as thief or fire, firm need cash to buy material immediately to continuously producing process and make orders delivers on time. Therefore, back-up money play important role in stable firm. Usually, risky firm have more motivation to divide cash for precautionary purpose than less risky ones. With this motive in mind, managers usually apply Baumol's approach. According this model, managers can determine optimal cash balance, upper and lower limit which cash balance is allowed to fluctuate. Hence, if cash balance reach to these limit, it will be
