Describe four levels of a cost hierarchy.
What are the key reasons for product cost differences between simple costing systems and ABC systems?
What are the main costs and limitations of implementing ABC systems?
Why is it important to classify costs into a cost hierarchy?
United Savings Bank (USB) is examining the profitability of its Premier Account, a combined savings and checking account. Depositors receive a \(2 \%\) annual interest rate on their average deposit. USB earns an interest rate spread of \(3 \%\) (the difference between the rate at which it lends money and the rate it pays depositors) by lending money for home-loan purposes at \(5 \%\). Thus, USB would gain \(\$ 60\) on the interest spread if a depositor had an average Premier Account balance of \(\$ 2,000\) in \(2017(\$ 2,000 \times 3 \%=\$ 60)\). The Premier Account allows depositors unlimited use of services such as deposits, withdrawals, checking accounts, and foreign currency drafts. Depositors with Premier Account balances of \(\$ 1,000\) or more receive unlimited free use of services. Depositors with minimum balances of less than \(\$ 1,000\) pay a \(\$ 22\) -a-month service fee for their Premier Account. Assume Lindell and Colston always maintain a balance above \(\$ 1,000\), whereas Welker always has a balance below \(\$ 1,000\) 1\. Compute the 2017 profitability of the Lindell, Welker, and Colston Premier Accounts at USB. 2\. Why might USB worry about the profitability of individual customers if the Premier Account product offering is profitable as a whole? 3\. What changes would you recommend for USB's Premier Account?
