The types of claims are dependent upon the nature of the corporation. For public companies, claims are primarily due to lawsuits by shareholders after financial difficulties, with a 2011 Towers Watson survey finding that 69% of publicly traded company respondents had a claim for a shareholder lawsuit in the past 10 years as opposed to 21% of private companies respondents. Other claims arise from shareholder-derivative actions, creditors (particularly after entering the zone of insolvency), customers, regulators (including those that would bring civil and criminal charges), and competitors (for anti-trust or unfair trade practice allegations). For nonprofits, claims are typically related to employment practice and less commonly regulatory or other fiduciary claims. For private companies, claims are often from competitors or customers for antitrust or deceptive business practices and one survey of 451 executives found that lawsuits cost an average of $308,475.
