The transactional fee pool accumulates on a daily basis and the yield payment is calculated on the last day of the month. The end-of-day balance is used to calculate all yields.
However, the KVT yield accrues daily, prior to payment, and is paid to the KVT holder of record on the last day of the calendar month. This means that any KVT transferred during the month is transferred with the accrued yield and the end-of-month payment is made to the new holder.
