Overhead items are accumulated in one overhead pool and allocated to the offices based on direct labor dollars. For 2010, this predetermined overhead rate was $1.90 for every direct labor dollar incurred. The overhead pool includes rent, depreciation, taxes, etc., regardless of which office incurred the expense. This method of accumulating costs forces the offices to absorb a portion of the overhead incurred by other offices.

Management is concerned with the results of the 2010 performance reports. During a review of overhead costs, it became apparent that many items of overhead are not correlated with direct labor dollars as previously assumed. Management decided that applying overhead based on activity based costing and direct tracing, when possible, should provide a more accurate picture of the profitability of each office. An analysis of the overhead revealed that the following dollars for rent, utilities, depreciation, and taxes could be traced directly to the office that incurred the overhead:

Morgantown
