To neglect this duty putsthose others at risk of consequences over which theyhave no control. Increasingly, governments and otherregulatory agencies are recognising the extent ofthese risks and, in the face of market failure to actappropriately, are embedding the obligations inlegislation and enforcing the legislation aggressively.Oversight of risk is a fundamental element ofgovernance for all types of organisation.
