Lewis and Stark is a public accounting firm that offers two primary services, auditing and tax-return preparation. A controversy has developed between the partners of the two service lines as to who is contributing the greater amount to the bottom line. The area of contention is the assignment of overhead. The tax partners argue for assigning overhead on the basis of 40% of direct labor dollars, while the audit partners argue for implementing activity-based costing. The partners agree to use next year's budgeted data for purposes of analysis and comparison. The following overhead data are collected to develop the comparison Estimated Use of Cost Drivers per Service Audit Tax Estimated Use of Cost Drivers $1,785,000 Estimated Overhead $214,200 $1,140,000 $645,000 Activity Cost Pools Employee training Typing and secretarial Computing Facility rental Cost Drivers Direct labor dollars Number of reports/forms Number of minutes 76,300 2,500 800 1,700 60,000 27,000 33,000 200,400 142.000 Number of employees 40 22 18 Travel Per expense reports 81,100 Direct 56,000 25,300 $714,000 Using traditional product costing as proposed by the tax partners, compute the total overhead cost assigned to both services (audit and tax) of Lewis and Stark.
