Galt Motors currently produces 500,000 electric motors a year and expects output levels
to remain steady in the future. It buys armatures from an outside supplier at a price of
$2.50 each. The plant manager believes that it would be cheaper to make these
armatures rather than buy them. Direct in-house production costs are estimated to be
only $1.80 per armature. The necessary machinery would cost $700,000 and would be
obsolete in 10 years. This investment would be depreciated to zero for tax purposes
using a 10-year straight line depreciation. The plant manager estimates that the
operation would require additional working capital of $40,000 but argues that this sum
can be ignored since it is recoverable at the end of the ten years. The expected proceeds
from scrapping the machinery after 10 years are estimated to be $10,000. Galt Motors
pays tax at a rate of 35% and has an opportunity cost of capital of 14%.
The IRR for Galt Motors of manufacturing the armatures in house is closest to:
A) 48%
B) 49%
C) 50%
D) 53%
Consider the following two projects:
Assume that projects A and B are mutually exclusive. The correct investment decision
and the best rational for that decision is to
A) invest in project A since NPVB< NPVA.
