Dear JP Morgan, page-28

There appears to be some confusion in your post Henry.
The original post was referenced from last year in regards to a major shareholder of JP Morgan announcing a 5% substantial holding in GXY today as a personal nod to the OP.
The parties listed in the announcement are subsidiaries of Blackrock Group that have accumulated the stock.
JP Morgan has no relevant interest in the announcement other than it's quoted status as another Blackrock investment along with many other large corporations.
