Liddel to leave GM next month

General Motors says Chris Liddell will leave the company next month after roughly a year as the vice chairman and chief financial officer.

Liddel, 52, joined the automaker in January, 2010 to lead the company’s financial and accounting operations on a global basis ahead of the initial public offering.

“Chris was a major contributor during a pivotal time in the company’s history,” said Dan Akerson, GM chairman and CEO in a release today. 

“He guided the company’s IPO process and established a good financial foundation for the future.”

He will be succeeded by Dan Ammann, 38, current V-P of finance and treasurer.
