Winkle, Kotter, and Zale is a small law firm that contains 10 partners and 12 support persons. The firm employs a job-order costing system to accumulate costs chargeable to each client, and it is organized into two departmentsthe Research and Documents Department and the Litigation Department. The firm uses predetermined overhead rates to charge the costs of these departments to its clients. At the beginning of the current year, the firm's management made the following estimates for the year:

	Department
	Research and Documents				Litigation
Research-hours		20,200				-
Direct attorney-hours		9,100				16,100
Materials and supplies	$	18,100			$	4,900
Direct attorney cost	$	429,600			$	800,100
Departmental overhead cost	$	686,800			$	312,039

The predetermined overhead rate in the Research and Documents Department is based on research-hours, and the rate in the Litigation Department is based on direct attorney cost.

The costs charged to each client are made up of three elements: materials and supplies used, direct attorney costs incurred, and an applied amount of overhead from each department in which work is performed on the case.
