US apparel firm Levi Strauss & Co has announced that its chief financial officer, Hans Ploos van Amstel, has decided to leave the company to pursue other career opportunities.

The company's corporate controller and principal accounting officer, Heidi Manes, will serve as CFO on an interim basis while the company recruits externally for a permanent replacement.

Ploos van Amstel has agreed to serve as its financial consultant for the next several months to help ensure a smooth transition.

Manes joined Levi's in 2002 from KPMG LLP and has held several leadership positions in its finance organisation so far.

"Heidi is steeped in the financial details of our global enterprise, and she played an integral role in developing our accounting policies, financial controls and external reporting practices," said Levi's chief executive officer John Anderson. "Heidi is well-positioned to lead the finance team through this transition."

Anderson also said: "Hans was a key contributor in strengthening the financial performance of the company during the past several years. He helped us to improve our capital structure, reduce costs and debt, and enhance our financial controls, accounting capabilities and reporting processes. We wish Hans the very best in his future endeavors."

Last month Levi's posted a 98% decline in second quarter income to US$1m, citing difficult economic conditions both in the Americas and further afield.

Its transition to a new enterprise resource planning system in the US negatively affected results too.

The jeans firm saw total quarterly revenue fall 8% to $936m, with sales in the Americas region down 20% to $477m on a constant currency basis, Europe down 4% to $268m and Asia Pacific nearly flat at $191m.
