PolyPlas Engineering Company Ltd manufactures plastic components for the car industry. The usual approach to overhead allocation adopted by the company, using machine hours as the sole cost driver, results in the following total cost per unit: 124.6 for product X; 115.11 for product Y and 159.6 for product W. The above product specifications are key plastic component of the car industry. However, a recently recruited management accountant of the company is concerned about the companys sole reliance on a volume-driven allocation base and suggested to management the need for him to be allowed to prepare an ABC analysis of product costs for the companys directors, and to make some recommendations based on his findings. The accountant relied on the following available budgeted information for the three key plastic components of the company to present the activity-based cost analysis.

	W per unit	X per unit	Y per unit
Selling price	200	183	175
Direct material	50	40	35
Direct labour	30	35	30
Units produced and sold	20 000	30 000	36 000

The total number of activities for each of the three products for the period is as follows:

	W	X	Y
Number of purchase requisitions	2 400	3 600	4 000
Number of set-ups	480	520	600

Overhead costs have been analysed as follows:

Receiving/inspecting quality assurance 2 800 000

Production scheduling/machine set-up 2 400 000

Required:

Calculate the total cost per unit of each product using an ABC approach. You should use your judgement to choose suitable cost drivers, based on the information provided in the question.

(24 marks)

Calculate the budgeted prot per unit for each of the three products using activity-based budgeting and traditional costing.

By comparing the solutions between (a) and the volume-driven total cost per unit for the three key plastic components, briefly explain how ABC can address the distortions of product costing linked to traditional cost accounting.

(10 marks)

Traditional costing system can make a considerable contribution to the under costing and over costing of products. Briefly discuss the effect of the above on sales and market.
