Interest accrued by your Treasury Account balance will be credited between the 15th and 17th of each month for the prior month's activity.
Interest is calculated based on the average monthly balance. Each day's ending balance is what is used to calculate that average monthly balance. Interest will accrue daily and will be posted to your account on a monthly basis based on a 30/365 day convention. The minimum average monthly balance in your Treasury Management Account required to earn interest is $25,000.00.
Treasury Account statements will be released by the 17th of each month in order to reflect that month's interest credit.
