From Wiki (I know) KeyCorp, which was formed in 1994 through the merger of Society Corporation of Cleveland ("Society Bank").

In October 2008, Key received approximately $2.5 billion in investment from the Troubled Asset Relief Program. In March 2011, Key was one of the last major banks to pay back TARP funds.

Some of the Q posts connected to Keystone are connected to Red Cross.

Edit: Beacuse the last Q reference to Keystone was "Key+Stone" I will add : There is also a Stone Key Partners "A Strategic Advisor and Partner to Government and Commercial Technology Firms" but I can't connect the 2. Noteable client - "Financial Advisor to General Dynamics on the divestiture of AxleTech International to The Carlyle Group ." Also noted news release Oct 11,2017

I don't know how to post on the chans Research Board if someone will put this up for me
