Activity-Based Supplier Costing

Bowman Company manufactures cooling systems. Bowman produces all the parts necessary for its product except for one electronic component, which is purchased from two local suppliers: Manzer Inc. and Buckner Company. Both suppliers are reliable and seldom deliver late; however, Manzer sells the component for $89 per unit, while Buckner sells the same component for $86. Bowman purchases 80% of its components from Buckner because of its lower price. The total annual demand is 4,000,000 components.

To help assess the cost effect of the two components, the following data were collected for supplier-related activities and suppliers:

I. Activity Data

	Activity Cost
Inspecting components (sampling only)	$825,000
Reworking products (due to failed component)	6,170,000
Warranty work (due to failed component)	9,670,000

II. Supplier Data

	Manzer Inc.	Buckner Company
Unit purchase price	$89	$86
Units purchased	800,000	3,200,000
Sampling hours*	80	3,920
Rework hours	360	5,640
Warranty hours	800	15,200

* Sampling inspection for Manzers product has been reduced because the reject rate is so low.

Required:

1. Calculate the cost per component for each supplier, taking into consideration the costs of the supplier-related activities and using the current prices and sales volume. (Note: Round the intermediate calculations to the whole number for the following activity rates: "Reworking products" and "Warranty work". Round the unit cost to two decimal places.)

Manzer Inc.	$fill in the blank 1per unit
Buckner Company	$fill in the blank 2per unit

2a. Suppose that Bowman loses $4,464,000 in sales per year because it develops a poor reputation due to defective units attributable to failed components. Using warranty hours, assign the cost of lost sales to each supplier.

Manzer	$fill in the blank 3
Buckner	$fill in the blank 4

2b. By how much would this change the cost of each supplier's component? Round your answers to the nearest cent.
