Lamar Company manufactures two products, Product K9 and Product L43. Product L43 is
of fairly recent origin, having been developed as an attempt to enter a market closely
related to that of Product K9. Product L43 is the more complex of the two products,
requiring 2.0 hours of direct labor time per unit to manufacture compared to 1.0 hour of
direct labor time for Product K9. Product L43 is produced on an automated production
line.
Overhead currently is applied to the products on the basis of direct labor-hours. The
company estimated it would incur $510,000 in manufacturing overhead costs and produce
10,000 units of Product L43 and 40,000 units of Product K9 during the current year.
Unit costs for materials and labor are:
Product K9
Product L43

$11
$24
Direct labor

Required:
a. Compute the predetermined overhead rate under the current method, and determine
the unit product cost of each product for the current year.
b. The company is considering the use of activity-based costing as an alternative to its
traditional costing method for manufacturing overhead. Data relating to the company's
activity cost pools for the current year are given below:

Harrison Industries has an activity-based costing system with three activity cost pools-
Processing, Batch Setup, and Other. The company's overhead costs, which consist of
factory utilities and indirect labor, are allocated to the cost pools in proportion to the
activity cost pools' consumption of resources. Costs in the Processing cost pool are
assigned to products based on machine-hours (MHs) and costs in the Batch Setup cost
pool are assigned to products based on the number of batches. Costs in the Other cost
pool are not assigned to products. Data concerning the two products and the company's
costs and activity-based costing system appear below:
