Question:

Case Construction Company, a three-year-old business, provides contracting and construction services to a variety of clients. Given that each construction job is different from the others, Susan Byrd, the company?s accountant, decided to use a job-order costing system to allocate costs to the different jobs. She decided to use construction labour-hours as the basis for overhead allocation. In December 2013, she estimated the following amounts for the year 2014:

Direct materials .................................. $14,560,000Construction labour ............................ $ 9,800,000Overhead .............................................. $ 7,510,000Construction labour-hours ...................... 500,000

Byrd recorded the following for the second quarter of 2014 for the three jobs that the company started and completed during the quarter.

2. Tyler Case, the company?s CEO, recently returned from a seminar on activity-based costing and instructed Kalagnanam to consider implementing the new system. As a first step, he instructed her to analyze the overhead costs for 2015. Through her research she was able to derive the following breakdown of the estimated overhead costs for 2015:

She also documented the following activity on the three jobs during the first quarter of 2015 (in addition to the construction labour-hours consumed by the three jobs):

Calculate the following:

a. The activity rates for each of the five activities.

b. The total cost of each job using activity-based costing.

3. Both Kalagnanam and Case are wondering if using activity-based costing will eliminate the existence of under- or overapplied overhead. As a managerial accountant, explain to them whether the use of activity-based costing will always result in zero under- or overapplied overhead.
