A credit card company has classified its customers into the following types for customer profitability analysis:
1. Applies for credit card in response to a low introductory interest rate; transfers balance to new account, but when the low introductory rate expires, the customer transfers the balance to an account with a different credit card company that has offered a low introductory rate.
2. Charges a large dollar volume of purchases; pays balance in full and on time each month.
3. Carries a high balance; pays only the minimum required payment but pays regularly with occasional late payment.
4. Carries a high balance; pays at least the minimum required payment but does not pay in full and always pays on time.
5. Carries a low balance; pays at least the minimum required payment but does not pay in full and always pays on time.
6. Does not use the account but does not close the account.
The following facts pertain to the credit card company’s operations:
• Merchants pay the credit card company a percentage of the dollar sales on each credit card transaction.
• Customers pay no interest on charges for purchases if the balance is paid in full and on time each month.
• The credit card company charges a late fee if the customer’s payment is late.
• The credit card company incurs costs to send statements to inactive customers.
