*Degree of completion for conversion costs at the dates of the work-in-process inventories
a2,200 beginning inventory + 21,000 – 1,800 spoiled – 1,900 ending inventory = 19,500.
b6% (21,000 units started – 1,800 units spoiled) = 6% 19,200 = 1,152; beginning work-in-process inventory is
excluded because it was already 20% complete at March 1 and past the inspection point.
c6% (23,200 units – 1,800) = 6% 21,400 = 1,284 because all units passed the 40% completion inspection point in
March.
d6% 19,500 = 1,170 because 19,500 units are fully completed and inspected during March.
18-40 (20 min.) Job costing, rework.
Avid Corporation manufactures a sophisticated controller that is compatible with a variety of
gaming consoles. Excluding rework costs, the cost of manufacturing one controller is $220. This
consists of $120 in direct materials, $24 in direct manufacturing labor, and $76 in manufacturing
overhead. Maintaining a reputation for quality is critical to Avid. Any defective units identified at
the inspection point are sent back for rework. It costs Avid $72 to rework each defective controller,
including $24 in direct materials, $18 in direct manufacturing labor, and $30 in manufacturing
overhead.
In August 2014, Avid manufactured 1,000 controllers, 80 of which required rework. Of these
80 controllers, 50 were considered normal rework common to all jobs and the other 30 were
considered abnormal rework.
Required:
1. Prepare journal entries to record the accounting for both the normal and abnormal rework.
2. What were the total rework costs of controllers in August 2014?
3. Suppose instead that the normal rework is attributable entirely to Job #9, for 200 controllers
intended for Australia. In this case, what are the total and unit costs of the good units produced
for that job in August 2014? Prepare journal entries for the manufacture of the 200 controllers,
as well as the normal rework costs.

2. The issues related to the determination of the percentage of spoilage considered normal
are similar to the factors discussed in Chapter 17 regarding the importance of verifying the
