Problem 5-15A Effect of automation on overhead allocation Bombay Rug Company makes two types of rugs, seasonal and all-purpose. Both types of rugs are handmade, but the seasonal rugs require significantly more labor because of their decorative designs. The annual number of rugs made and the labor hours required to make each type of rug follow. Seasonal All-Purpose Number of rugs 2,400 5,600 Number of direct labor hours 120,000 168,000 Totals 8,000 288,000 Required a. Assume that annual overhead costs total $172,800. Select the appropriate cost driver and determine the amount of overhead to allocate to each type of rug b. Bombay automates the seasonal rug line, which results in a dramatic decline in labor usage and allows the company to make 2,400 rugs in only 12,000 hours. Bombay continues to make the all-purpose rugs the same way as before. The number of rugs made and the labor hours required to make them after automation follow. Seasonal All-Purpose Totals Number of rugs 2,400 12,000 5,600 168,000 8,000 180,000 Number of direct labor hours Overhead costs are expected to increase to $216,000 as a result of the automation. Allocate the increased overhead cost to the two types of rugs using direct labor hours as the allocation base and comment on the appropriateness of the allocation
