Sounds to me like someone is sitting around thinking up new and creative ways to get more money out of the examiner's pocket.  Now, the way it was explained to me, an E & O policy is a "claims-made" policy which covers any claims made during the time the policy is in force.  Only when there is a lapse in coverage is a prior claim excluded from the policy.

You didn't say what company you're with, but I got good service and a reasonable rate from State Farm.
