Ted Dreyer,
I don't know why a statement message would be considered more clear and conspicuous than permanent language on the back of a required periodic statement. I don't think customer's pay attention to anything that appears on their statements unless they are specifically looking for something.
Seems to me that putting the language on periodic statements as a permanent feature would be a simple solution. However, as others have noted, we would have to do the same thing we have always done in the past and identify those customers that do not receive statements and mail the notice to them separately.
