Make versus buy, activity-based costing. The Svenson Corporation manufactures cellular modems. It manufactures its own cellular modem circuit boards (CMCB), an important part of the cellular modem. It reports the following cost information about the costs of making CMCBs in 2014 and the expected costs in 2015:

Svenson manufactured 8,000 CMCBs in 2014 in 40 batches of 200 each. In 2015, Svenson anticipates needing

10,000 CMCBs. The CMCBs would be produced in 80 batches of 125 each.

The Minton Corporation has approached Svenson about supplying CMCBs to Svenson in 2015 at $300

per CMCB on whatever delivery schedule Svenson wants.

1. Calculate the total expected manufacturing cost per unit of making CMCBs in 2015.

2. Suppose the capacity currently used to make CMCBs will become idle if Svenson purchases CMCBs

from Minton. On the basis of financial considerations alone, should Svenson make CMCBs or buy them

from Minton? Show your calculations.

3. Now suppose that if Svenson purchases CMCBs from Minton, its best alternative use of the capacity

currently used for CMCBs is to make and sell special circuit boards (CB3s) to the Essex Corporation.

Svenson estimates the following incremental revenues and costs from CB3s:

On the basis of financial considerations alone, should Svenson make CMCBs or buy them from

Minton? Show your calculations.
