What is the competitive situation faced by Wilkerson?
Given some apparent problems with Wilkerson's cost system, should executives abandon overhead assignment to products entirely by adopting a contribution margin approach in which manufacturing overhead is treated as a period expense? Why or why not?
Prepare the following calculations. Create a table using Excel to show your answers with details support your answer. Be sure to use $ signs where appropriate. Copy and paste as picture into Word document.
Calculate the unit product cost for each product using the direct-labor-based cost allocation system.
Calculate the unit product cost for each product using activity based costing to allocate the cost of manufacturing overhead, as well as profitability for each product line. Overhead cost pools include machine, setup, receiving/scheduling, engineering support and packing/shipping products.
Compare your work in question 3a. and 3b. above. Why have cost shifts occurred?
