    <remarks>On the original filing date 6/16/2021, the sale transaction on 6/15/2021 listed the incorrect transaction code as &quot;P&quot; in Table I column 3.  This transaction code should have been listed as &quot;S&quot;.  This Form 4A is being submitted as an amendment to that Form 4 filed on 6/16/2021.</remarks>
