The gross amount of reportable transactions is defined as the total dollar amount of all reportable payment transactions for each participating payee. This amount is calculated without considering any adjustments for credits, cash equivalents, discount amounts, fees, refunded amounts, or any other amounts. The dollar amount of each transaction is determined on the date of the transaction.
