The following data refer to the successful Munger division of Buffett, Inc. Munger makes and
sells high-end cordless drills. The drills sell for $80 each, and Munger expects sales of 300,000
units in 2014. Munger’s annual fixed costs are $4 million. The variable cost per drill is $48.
Buffett evaluates Munger based on residual income. The total investment attributed to
Munger is $16 million, and Buffett has a required rate of return on investment of 20%.
Ignore taxes and depreciation expense. Answer each of the following parts independently,
unless otherwise stated.
Required:
1. What is the expected residual income in 2014?
2. Munger receives an external special order for 100,000 units at $60 each. If the order is
accepted, Munger will have to incur incremental fixed costs of $850,000 and invest an
additional $2 million in various assets.
What is the effect on Munger’s residual income of accepting the order?
3. One of the components Munger manufactures for its drill has a variable cost of $4. An
outside vendor has offered to supply the 300,000 units required at a cost of $5.25 per unit. If
the component is purchased outside, fixed costs will decline by $200,000 and assets with a
book value of $760,000 will be sold at book value.
Will Munger decide to make or buy the component? Explain your answer.
4. One of Munger’s regular customers asks for a special drill made of tempered steel. The
customer requires 15,000 drills. Munger estimates its variable cost for these special units at
$54 apiece. Munger will also have to undertake new investment of $1,500,000 to produce the
drills.
What is the minimum selling price that will make the deal acceptable to Munger?
