He isn't CEO of Flint, he's CFO, Corporate Secretary and Chairman of the Board. I'm guessing Bernard Fried is CEO.

Mr. Browne is also currently Chairman of the Board, Corporate Secretary and acting Chief Financial Officer for Flint Telecom Group, Inc. (“Flint”).
Also, from the email in the stickies, he signs as Chairman:-
