Lewis and Stark is a public accounting firm that offers two primary services, auditing and tax$-$retum 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 overbead 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 the purposes of analysis and comparison. The following overhead data are collected to develop the comparison.
