Question

Division A manufactures electronic circuit boards. The boards can be sold either to Division B of the same company or to outside customers. Last year, the following activity occurred in Division A:

Selling price per circuit board	$	178
Variable cost per circuit board	$	119
Number of circuit boards:
Produced during the year		21,100
Sold to outside customers		15,500
Sold to Division B		5,600

  
Sales to Division B were at the same price as sales to outside customers. The circuit boards purchased by Division B were used in an electronic instrument manufactured by that division (one board per instrument). Division B incurred $200 in additional variable cost per instrument and then sold the instruments for $610 each.

Required:

1. Prepare income statements for Division A, Division B, and the company as a whole.

2. Assume Division A’s manufacturing capacity is 21,100 circuit boards. Next year, Division B wants to purchase 6,600 circuit boards from Division A rather than 5,600. (Circuit boards of this type are not available from outside sources.) From the standpoint of the company as a whole, should Division A sell the additional 1,000 circuit boards to Division B or continue to sell them to outside customers?
