I know Business Accounts are not covered under REG E, but:
1. what do most financial institutions do when a Business Account has an unauthorized ATM withdrawal, POS Purchase or an unauthorized ACH debit hit their account and they dispute it.
2. In the case of an ACH dispute on a Business account does the business eat the loss and the FI just tries to process the disputed transaction as an unauthorized ACH but does not issue a provisional credit? When and if the funds are returned by the other FI the bank would then credit the business acoount?
