PNC Investments uses the Broker Call Rate. The Broker Call Rate will change without prior notice. When the Broker Call Rate changes during an interest period, interest will be calculated according to the number of days each rate was effective during that period. You will be provided 30 days advanced notice of any change to the schedule of charges other than that of the Base Lending Rate. There is no repayment schedule, but interest is posted to your account monthly and requests for additional margin may be made if market conditions warrant or otherwise at the discretion of PNC Investments and/or its clearing agent Pershing per the terms of your Margin Agreement. This is neither an offer to sell nor a solicitation of an offer to buy any of these securities. This data appears for informational purposes only.
