These percentages indicate that some companies have directors who don't understand their responsibilities as the representatives of shareholders. The shareholders of those companies should be asking the directors how they govern an organization without a good understanding of the risks the company is facing and without knowledge of a systematic approach to identifying, assessing, monitoring, and mitigating excessive risk-taking.
I trust that none of the directors who participated in the survey were on the board of a financial services company. Although directors are not expected to understand every nuance of every line of business or to oversee every transaction, they do have responsibility for setting the tone regarding their corporations' risk-taking and establishing an effective monitoring program.
