Revenue Recognition

Revenue from contracts with customers comprises the noninterest income earned by the Company in exchange for services provided to customers.  Income associated with customer contracts generally involve transaction prices that are fixed and performance obligations which are satisfied as services are rendered.  In most cases recognition occurs within a single financial reporting period as there is little or no judgement involved in the timing of revenues.  We generally act in a principal capacity, on our own behalf, in most of our contracts with customers.  In such transactions, we recognize revenue and the related costs to provide our services on a gross basis in our financial statements.  Service Charges on Deposit Accounts comprise charges on retail and business accounts.  Business customers can earn credits depending on account type and deposit balances maintained with the Company, which may be used to offset fees.  Fees and credits are based on predetermined, agreed-upon rates.  In some cases, we act in an agent capacity, deriving revenue through assisting other entities in transactions with our customers.  In such transactions, we recognize revenue and those related costs to provide services on a gross basis in our financial statements.  Debit card interchange income is derived from our customers’ use of various interchange and ATM/debit card networks which are the primary sources of revenue generated in an agent capacity.
