SEC
In September 2010, Flannery and James D. Hopkins, former head of SSgA North American Product Engineering, were charged with misleading investors about the risks and concentration of subprime investments in State Street bonds funds. Flannery and Hopkins opted not to settle and were cleared of all charges in October 2011 by Brenda Murray, the chief administrative law judge of the SEC. She determined that the SEC did not show how Flannery and Hopkins' interactions with investors had broken any securities laws. In her decision, Judge Murray noted that “Flannery has had an unblemished record in the industry and those who have worked with him believe him to be unusually honest, capable, and ethical.”
