Tiger Manufacturing makes a component called A1030. This component is manufactured only when ordered by a customer, so Tiger keeps no inventory of A1030. The list price is $155 per unit, but customers who place "large" orders receive a 14% discount on price. The customers are manufacturing firms. Currently, the salespeople decide whether an order is large enough to qualify for the discount. When the product is finished, it is packed in cases of 10. If the component needs to be exchanged or repaired, customers can come back within 10 days for free exchange or repair.The full cost of manufacturing a unit of A1030 is $120. In addition, Tiger incurs customer-level costs. Customer-level cost-driver rates are:

Order taking	$280	per order
Product handling	$14	per case
Rush order processing	$600	per rush order
Exchange and repair costs	$65	per unit

1.	Calculate the customer-level operating income for these five customers. Prepare a customer-profitability analysis by ranking the customers from most to least profitable.
