EXERCISE 7-7 First-Stage Allocations L07-20 The operations vice president of Security Home Bank has been interested in investigating the efficiency of the bank's operations. She has been particularly concerned about the costs of handling routine transactions at the bank and would like to compare these costs at the bank's various branches.

While the bank maintains meticulous records of wages and other costs, there has been no attempt thus far to show how those costs are relate s are related to the various services provided by the bank.

In particular, she would like to know the cost of opening an account, the cost of processing deposits and withdrawals, and the cost of processing other customer transactions The Westfield branch of Security Home Bank has submitted the following cost data for last year: Teller wages Assistant branch manager salary Branch manager salary Total $160,000 75,000 80,000 $315,000 Virtually all other costs of the branch-rent, depreciation, utilities, and so on-are organization-sustaining costs that cannot be meaningfully assigned to individual customer transactions such as depositing checks. In addition to the cost data above, the employees of the Westfield branch have been interviewed concerning how their time was distributed last year across the activities included in the activity-based costing study. The results of those interviews appear below: Distribution of Resource Consumption Across Activities Processing Teller wages Assistant branch manager salary Branch manager salary Processing Opening Deposits and Accounts Withdrawals 5% 65% 15% 5% 5% 0% Other Customer Other Transactions Activities 20% 10% 30% 50% 10% 85% Total 100% 100% 100% Required: Prepare the first stage allocation for the activity-based costing study.
