Exercise 2

Job Costing in a Service Organization
At the beginning of the month, Arthur's Olde Consulting Corporation had two jobs in process that had the following costs assigned from previous months:

During the month, Jobs SY-400 and SY-403 were completed but not billed to customers. The completion costs for SY-400 required $8,400 in direct labor. For SY-403, $24,000 in labor was used.
During the month, the only new job, SY-404, was started but not finished. Total direct labor costs for all jobs amounted to $49,440 for the month. Overhead in this company refers to the cost of work that is not directly traced to particular jobs, including copying, printing, and travel costs to meet with clients. Overhead is applied at a rate of 60 percent of direct labor costs for this and previous periods. Actual overhead for the month was $30,000.
