and reduce risk. New CEOs result from non-routine turnovers have more concerns because
they do not have much track records with and trust from the board. The coefficient of routine
CEO turnover is not significantly related to change in reinsurance demand when compared to
insurers without CEO turnover in all Models. Because new routine CEOs are familiar with
the direction of the board, they tend to follow the original reinsurance decision as well. This
result is rejects Hypothesis 2. Other results of Table 4 show that corporate governance and
control variables which are statistically significant are similar to those in Table 3.
