7. Andy Hornby
Andy Hornby was considered to be a rising star in the financial world. He was respected and admired, graduating at the top of his class at Harvard. Unfortunately, he made a few missteps at HBOS, a banking and insurance firm in the United Kingdom; he took over as chief executive, along with Halifax. His mismanagement of finances and attempt to apply the same terms and conditions as the Bank of Scotland led to HBOS being taken over by the Lloyds TBS Group. In 2013, the Banking Standards Commission recommended barring Hornby from all future roles in the financial sector.
