Calgary-based Advantage Oil & Gas (NYSE:AAV) needs a new CFO.

On Thursday, after close of trading, Advantage announced that Chief Financial Officer Mr. Kelly Drader has resigned from the company "to focus on his role as President and Chief Executive Officer of Longview Oil Corp," a company to which Advantage sold some of its oilfield properties in West Central Alberta, Southeast Saskatchewan, and the Lloydminster area of Saskatchewan.

Advantage Vice President for Finance is taking over Drader's duties in the capacity of Interim CFO, while a permanent replacement is sought.

Advantage continues to own a 45% stake in Longview, the company that Drader CEOs.
