Hertz Global Holdings (HTZG.Q) is now officially in the hunt for a permanent chief financial officer. The company announced that Elyse Douglas, who is the company's CFO as well as executive vice president, will step down effective Oct. 1. She will, however, remain with the company in an advisory capacity until the end of the year. In the press release announcing the resignation, the car-rental giant said only that she was resigning for "personal reasons."

Filling the role on an interim basis will be David Rosenberg, currently CFO of Hertz International. He has been with the company since 2009 and before that held various finance executive positions at such concerns as Ralph Lauren and Nabisco, now owned by Mondelez International.

Hertz said it is evaluating both external and internal candidates to be its next permanent CFO.
