In various fields there is a problem with people who retire or close down their businesses with ‘tail insurance.’  The problem is that a liability issue can come up much later.  Much of the coverage that’s sold only covers suits that are later reported for injuries that occur during the policy period.  It’s hard or doctors or persons producing lasting products to get coverage for an injury that occurs after the policy expires but is  caused by an action that occured while the person was in business.
