Under revised Article 4, a bank is no longer required to include the customer's canceled checks when it sends monthly statements to the customer. Some of you may remember when banks sent checks back to the account holder after being processed. If you don't, ask your parents about it. They may shed some light on the practice and their preferences since it ceased. A bank may simply itemize the checks (by number, date, and amount). It may provide photocopies of the checks as well but is not required to do so. What implications do these rules have for bank customers in terms of liability for unauthorized signatures and endorsements? Discuss fully.
