Here is some additional information I found:
A customer must notify its bank of unauthorized payments "promptly" after receipt of its statement and discovery of the facts. UCC § 4-406(c). If it does not do so, it may not recover to the extent of any loss the delay caused the bank. UCC § 4-406(d)(1). Where a series of forgeries is involved, the customer's failure to use due care in examining its statement and notifying the bank of unauthorized items can be a defense if notification would have prevented payment on subsequent forgeries. UCC § 4-406(d)(2). However, in either instance, if the bank pays the item in bad faith or is itself negligent in paying the item, that fact may leave all or some portion of the loss with the bank. UCC § 4-406(e).
If the customer does not report an unauthorized signature within one year after receipt of its monthly statement, it is precluded from raising the claim, whether or not negligence was involved. UCC § 4-406(f). Some courts have permitted the deposit agreement to shorten this outside limit for reporting unauthorized payments to as little as 14 days and to have the reporting period commence to run on the date of mailing, rather than the date of receipt of the statement by the customer. The only requirement for this type of contractual reduction of the one year reporting period is that the shorter period be reasonable and be clearly disclosed to the customer.
In my opinion, the customer's normal period for raising disputes can be extended to one year in instances in which the bank did not exercise ordinary care in handling the account. Whether or not the bank exercised ordinary care is something that can only be determined in court, but failure to police maker signatures at all on accounts will probably be deemed a lack of ordinary care on the bank's part.
