and prospects, general economic conditions, other developments and additional investment opportunities. Depending on such assessments and in compliance with any applicable agreements, the Reporting Persons may acquire additional securities of the
Issuer or new securities of the Issuer, engage in any hedging or similar transactions with respect to the Issuers securities, or may determine to sell or otherwise dispose of all or some of the Issuers securities in the open market, as
applicable, in privately negotiated transactions, in transactions directly with the Issuer or otherwise. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices, the financial
condition, results of operations and prospects of the Issuer, alternative investment opportunities, general economic, financial market and industry conditions and other factors that the Reporting Persons may deem material to their investment
decision.
