These transactions were approved by the Issuer's board of directors pursuant to Rule 16b-3 under the Securities and Exchange Act of 1934, as amended. ( 2 )This holding was decreased by one share from the Form 4 filed by the reporting person on February 22, 2018, as a result of an accounting reconciliation. ( 3 )Mr. Duncan's daughter is the beneficiary of this trust. Mr. Duncan has no voting or investment power with respect to the trust and disclaims beneficial ownership of these shares.
