Comment on the comparative total costs per unit under traditional costing and ABC.

Problem P4-1B, Waves Galore, Inc. manufactures hair curlers and
blow-dryers. The handheld hair curler is Waves Galore’s high volume
product, 80,000 units annually. It is a “large barrel”, 20-watt,
triple-heat appliance designed to appeal to the teenage market segment
with its glow-in-the-dark handle. The handheld blow-dryer is Waves
Galore’s lower-volume product, 40,000 units annually. IT is a
three-speed, 2,000 watt appliance with a “cool setting” and a removable
filter. It also is designed for the teen market. Both products
require 1 hour of direct labor for completion. Therefore, total annual
direct labor hours are 120,000 (80,000 + 40,000). Expected annual
manufacturing overhead is $441,600. Thus, the predetermined overhead
rate is $3.65 per direct labor hour. The direct material cost per unit
is $5.25 for the hair curler and 9.75 for the blow-dryer. The
direct labor cost is $8.00 per unit for the hair curler and
Waves Galore purchases most of its parts from suppliers and
assembles the finished products at its Fargo, North Dakota plant. It
recently adopted activity-based costing, which after year-end will
totally replace its traditional direct labor-based cost accounting
system. Waves Galore has identified the following six activity cost
pools and related cost drivers and has assembled the following
Activity Cost Pool Cost Driver Estimated Overhead Expected Use of Cost Drivers Expected Use of Drivers by Product
Curlers Dryers
Purchasing Orders $57,500 500 170 330
Receiving Pounds 42,000 140,000 58,000 82,000

(a) Under traditional product costing, compute the total unit cost
of both products. Prepare a single comparative schedule of the
individual costs by products, in the format provided below.
(b) Under ABC, prepare a schedule showing the computations
of the activity-based overhead rates (per cost driver).
(c) Prepare a schedule assigning each activity’s overhead cost pool
to each product based on the use of cost drivers. (Include a computation
of overhead cost per unit, rounding to the nearest cent.)
(d) Compute the total cost per unit for each product under ABC.
(e) Classify each of the activities as a value-added activity or a non-value-added activity.
(f)(1) Comment on the comparative overhead cost per unit for the two products under ABC.
(f)(2) Comment on the comparative total costs per unit under traditional costing and ABC.
