142) 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
Direct material $ 11 $ 24
Direct labor 6 12
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:
Total Activity
Activity Cost Pool Total Cost Product K9 Product L43
Total
Machine setups required $ 204,000 800 1,600 2,400
Purchase orders issued 43,500 500 100 600
Machine-hours required 105,000 7,000 10,500 17,500
Maintenance requests issued 157,500 650 850 1,500
$ 510,000
Using the data above, determine the unit product cost of each product for the current year.
c. What items of overhead cost make Product L43 so costly to produce according to the activity-
based costing system? What influence might the activity-based costing data have on
management’s opinions regarding the profitability of Product L43?
