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 Activity Cost Pools Cost Drivers Employee training Direct labor dollars Typing and secretarial Number of reports/forms Computing Number of minutes Facility rental Number of employees Travel Per expense reports Estimated Overhead $217,500 76,400 204,000 146,000 81,100 $725,000 Estimated Use of Cost Drivers per Service Estimated Use of Cost Drivers Audit Tax $1,812,500 $1,108,000 $704,500 2,500 800 1,700 60,000 27,000 33,000 2218 Direct 56,000 25,300 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.
