Navistar announced it is restructuring its senior leadership team, along with the retirement of Jack Allen, executive vice president and chief operating officer.

Bill Kozek, president of Navistar’s North America truck and parts, has been promoted to president of truck and parts, and is adding global/export truck and parts sales, product planning and Navistar Defense to his current responsibilities.

Persio Lisboa, senior vice president and chief procurement officer, has been promoted to president of operations and is now also responsible for product development, manufacturing, and global businesses.

Walter Borst, executive vice president and chief financial officer, is adding business development, mergers and acquisitions, and corporate strategic planning responsibilities to his responsibilities.

“Today is a new beginning for Navistar," said Troy Clarke, Navistar president and CEO. "We are introducing a new leadership team and organization structure that will guide us into the future and enable us to accelerate our performance now that our turnaround is behind us."

The company also announced Jack Allen, executive vice president and chief operating officer since April 2013, is retiring after more than 33 years of service with Navistar.

"Jack has been an important leader at this company for more than three decades, and he played a critical role during our turnaround these past two years," Clarke said. "Now, we are counting on these three talented and energetic leaders to work with me and the rest of the organization to drive Navistar forward on its path to profitable growth."

All of the changes are effective immediately.

Borst joined Navistar in August 2013 from General Motors, where he most recently was the chairman, chief executive officer and president of GM Asset Management, responsible for managing approximately $85 billion in assets.

Kozek joined Navistar in May 2013 after more than 26 years with Paccar, where he served as vice president and general manager of the Peterbilt division, responsible for all aspects of Peterbilt's U.S. and Canadian operations.

Lisboa joined the company in 1988 in the marketing area of Maxion International Motores Brasil. Prior to roles in procurement, Lisboa served as vice president and general manager in the company's engine group, as well as several other leadership positions in South America.
