Andrew J. (A.J.) Cederoth, executive vice president and chief financial officer of Navistar International Corp., will leave the company at the end of the month, Navistar announced.

The company said Cederoth’s departure is part of a “planned transition to a new CFO.” Cederoth, 48, has served as the company’s CFO since September 2009.

James M. Moran, Navistar senior vice president and treasurer, will oversee the company’s financial operations and functions on an interim basis, while the company finalizes its appointment of a new CFO from outside the company.

“I want to thank A. J. for his many contributions during his 23 years at Navistar, particularly the leadership he displayed this past year in helping to create, implement and drive significant progress in our turnaround plan,” said Troy A. Clarke, Navistar’s president and CEO. “I also appreciate the support A. J. provided during this CFO transition process. He has had a distinguished career at Navistar and we wish him well in his future endeavors.”
