Division A manufactures electronic circuit boards. The boards can be sold either to Division of the same company or to outside customers. Last year, the following activity occurred Division A:
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 $100 in additional variable cost per instrument and then sold the instruments for $300 each.
1. Prepare income statements for Division A, Division B, and the company as a whole.
2. Assume that Division A’s manufacturing capacity is 20,000 circuit boards. Next year, Division B wants to purchase 5,000 circuit boards from Division A rather than 4,000. (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 1,000 additional circuit boards to Division B or continue to sell them to outside customers? Explain.
