At the end of each business day, transactions are processed in what is known as nightly processing. We start with your account’s current balance as of the end of the prior business day. Your current balance will first be reduced by "pending" withdrawals, such as debit card transactions that we have authorized but not yet paid. Then, we subtract holds placed on a deposit to your account and holds placed due to legal process. The resulting balance becomes your available balance which will be used in nightly processing.
Next, transactions will be sorted into groups and prioritized by Group (items in Group 1 would post before items in Group 2 and items in Group 2 would post before items in Group 3, etc.). Within each group, items will be posted by time authorized (e.g. when you got gas with your debit card), performed (e.g. when you took money out at the ATM), received (e.g. when your gym debited your monthly membership fee) or processed by the bank. When items are received at the same time, we will post those in "low to high", or ascending, dollar amount order.
