Explanation of Responses:

( 1 )The transactions reported in this Form 4 were executed by the reporting person's investment advisor in a managed account as part of the investment advisor's implementation of a managed investment strategy involving the securities of multiple issuers. These managed accounts are held in a trust for which the reporting person is a trustee and/or beneficiary. The reporting person was unaware of the transactions at the time they occurred and did not exercise any investment control over the purchases and sales.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
