The top portion of the notice does have the 3 items needed for the error, 1. Name and account #, 2. Description of the error and, 3. Dollar amount of the error.
I feel though that it is the long form only because it's quite lengthy and then goes into incorporating the Reg E timelines for investigation, provisional credit, timeframe for new accounts, etc...
So, if it is the long form and the customer already received their statement, I don't believe we would have to add the Notice again, with a reprint of their statement, as they have already recevied it.
Although, I would feel more comfortable just incorporating it across the board so that I know it's not going to cause problems.
