Yes. But what payouts have taken place?
Dick, I have no idea, but I suspect none at all, nada, zip. My opinion is that indemnity insurance has been foisted upon us by insurance companies and is taken out by gullible folk who believe in the fear propagated by the insurance and legal industry.
It is also my opinion that with insurance you are more likely to get sued. If you don't have it, it could be just too hard for the "percentage of win" lawyer.
In 40 years of self employment in variety of industries I have never had a policy. I see no reason to change my stance.
