Options trading entails significant risk and is not appropriate for all customers. It is important that investors read Characteristics and Risks of Standardized Options before engaging in any options trading strategies. Options transactions are often complex and may involve the potential of losing the entire investment in a relatively short period of time. Certain complex options strategies carry additional risk, including the potential for losses that may exceed the original investment amount. Supporting documentation for any claims, if applicable, will be furnished upon request.

The past performance of a security or financial product does not guarantee future results or returns. Customers should consider their investment objectives and risks carefully before investing in options. Because of the importance of tax considerations to all options transactions, the customer considering options should consult their tax advisor as to how taxes affect the outcome of each options strategy.
