US online brokerage TD Ameritrade says its chief operating officer (COO) David Kelley is leaving the company.
Kelley joined TD Ameritrade five years ago, becoming COO in 2008, responsible for overseeing operations and technology, including back-office support for retail client service and the institutional and clearing business units.
In a Securities and Exchange Commission filing, the firm says Kelley's employment was terminated on 20 January, effective of the 28th. A brief statement says he has left to "pursue other opportunities".
Commenting on the departing executive, Fred Tomczyk, president and CEO, TD Ameritrade, says: "He has built a strong technology and operations platform for the company and we are in a good position to transition and increase focus on our front end technology."
According to the Wall Street Journal, the company has been hit by several technology problems over the last few months, affecting both its main platform and the thinkorswim system.
