Chris Liddell announced that he will leave General Motors on April 1.

In a press release Thursday morning, the company stressed  Liddell is stepping down after completing the largest public stock offering in history and stabilizing the company's financial operations.

 Liddell joined the car maker in January, 2010 and led the company's financial and accounting operations on a global basis.  

"Chris was a major contributor during a pivotal time in the company's history," said Dan Akerson, GM chairman and CEO.  "He guided the company's IPO process and established a good financial foundation for the future."

Akerson also credited Liddell in part for GM's sustained profitability, strengthened balance sheet and elimination of material weakness in the financial reporting process.

Liddell will be succeeded by Dan Ammann, currently GM's vice president, finance and treasurer.

"Dan's depth of knowledge of the financial community and our business will be instrumental as we continue to earn the trust of global investors and customers," said Akerson.  "He is held in high regard on Wall Street and within the company and, as we move our financial strategy forward, his credibility and leadership will be invaluable."

GM said Ammann has played a major role in the key financial decisions at the new GM.  He is also said to have been actively engaged in setting the financial strategy and reducing debt.  

Ammann joined GM in March, 2010, leading the company's Treasurer's Office. Prior to GM, Ammann was managing director and head of Industrials Investment Banking for Morgan Stanley and was instrumental in many high profile assignments spanning a variety of technology, service, and manufacturing clients.

GM has not named a successor for Ammann in GM's Treasurer's Office.
