Jean-François Théodore, deputy chief executive of the newly merged NYSE Euronext, was paid less than a fifth of the amount earned by his new boss John Thain last year.

Théodore earned €1.33m ($1.81m) as chief executive of Euronext, according to the exchange's annual report published last week. Thain, chief executive of the combined exchange, earned more than five times as much as chief executive of NYSE Group, taking home $9.36m (€6.9m).
