Our Automated Investment Sweep can help you earn money overnight on idle checking account balances.  Every night, after all checks and deposits have cleared, excess funds are swept into an overnight investment account. The funds remain available at all times to cover checks and other withdrawals from the checking account. Earnings are credited daily to your account. Your checking account statement will detail all sweep activity. You can even use the sweep option to pay down or draw from a business line of credit. Sweep investments are not deposit accounts and are not insured by the FDIC.
