Explanation of Responses:

Remarks:

Amendment is being filed because transactions were originally reported early - as occurring on 5/20-5/22 (the dates the gifts were authorized). Broker actually process gifts and transferred shares on 5/26-5/28/20. In addition, one gift was erroneously undereported as 679 shares, but was actually for 1,359 shares.
