Online brokerage firm Ameritrade is reporting the resignation of its co-chief information officer Mok Choe.
In a brief statement, Ameritrade says Choe is leaving the company "to pursue another opportunity". His fellow co-chief Raymond Dury remains as leader of Ameritrade's technology group. A permanent decision on the vacant position will be made in the near future, says the brokerage.
Choe and Dury were given the co-CIO roles during a major organisational reshuffle in June, which also marked the departure of incumbent CIO Joe Ditmore.
