As you learned in the previous chapters, Current Designs has two main product linescomposite kayaks, which are handmade and very labor-intensive, and rotomolded kayaks, which require less labor but employ more expensive equipment. Current Designs' controller, Diane Buswell, is now evaluating several different methods of assigning overhead to these products. It is important to ensure that costs are appropriately assigned to the company's products. At the same time, the system that is used must not be so complex that its costs are greater than its benefits. Diane has decided to use the following activities and costs to evaluate the methods of assigning overhead. Activity, Cost: Designing new models $121,100, Creating and testing prototypes 152,000, Creating molds for kayaks 188,500, Operating oven for the rotomolded kayaks 40,000, Operating the vacuum line for the composite kayaks 28,000, Supervising production employees 180,000, Curing time (the time that is needed for the chemical processes to finish before the next step in the production process; many of these costs are related to the space required in the building) 190,400, Total $900,000. As Diane examines the data, she decides that the cost of operating the oven for the rotomolded kayaks and the cost of operating the vacuum line for the composite kayaks can be directly assigned to each of these product lines and do not need to be allocated with the other costs. Instructions: For purposes of this analysis, assume that Current Designs uses $234,000 in direct labor costs to produce 1,000 composite kayaks and $286,000 in direct labor costs to produce 4,000 rotomolded kayaks each year. (a) One method of allocating overhead would allocate the common costs to each product line by using an allocation basis such as the number of employees in working on each type of kayak or the amount of factory space used for the production of each type of kayak. Diane knows that about 50% of the area of the plant and 50% of the employees work on the composite kayaks, and the remaining space and other employees work on the rotomolded kayaks. Using this information, and remembering that the cost of operating the oven and vacuum line have been directly assigned, determine the total amount to be assigned to the composite kayak line and the rotomolded kayak line, and the amount to be assigned to each of the units in each line. (b) Another method of allocating overhead is to use direct labor dollars as an allocation basis. Remembering that the costs of the oven and the vacuum line have been assigned directly to theproduct lines, allocate the remaining costs using direct labor dollars as the allocation basis. Then, determine the amount of overhead that should be assigned to each unit of each product line using this method. (d) Which of the three methods do you think Current Designs should use? Why
