Soon after taking the reins of MF Global in 2010, Jon S. Corzine visited the Wall Street firm’s Chicago offices for the first time, greeting the brokers, analysts and sales staff there.
One broker, Cy Monley, caught Mr. Corzine’s eye. Unknown to MF Global’s top management in New York, the employee, whose job was to match buyers and sellers in energy derivatives, was also trading a small account on the side, using the firm’s capital.
“How are you making money on side bets? What else are you guys doing to make money here?” Mr. Corzine asked enthusiastically, his eyes widening, the broker recalled. The new chief executive grabbed a seat and spent an hour questioning Mr. Monley as other top executives from New York hovered impatiently nearby.
