Chapter 20 – External Growth through Mergers
11. Portfolio effect of a merger (LO20-4) Assume the Knight Corporation is considering the
acquisition of Day Inc. The expected earnings per share for the Knight Corporation will be
$4.00 with or without the merger. However, the standard deviation of the earnings will go
from $2.40 to $1.60 with the merger because the two firms are negatively correlated.
a. Compute the coefficient of variation for the Knight Corporation before and after the
merger (consult Chapter 13 to review statistical concepts if necessary).
b. Discuss the possible impact on Knight’s postmerger P/E ratio, assuming investors are
risk-averse.

12. Portfolio consideration and risk aversion (LO20-4) General Meters is considering two
mergers. The first is with Firm A in its own volatile industry, the auto speedometer
industry, while the second is a merger with Firm B in an industry that moves in the
opposite direction (and will tend to level out performance due to negative correlation).
a Compute the mean, standard deviation, and coefficient of variation for both investments
(refer to Chapter 13 if necessary).
