Footwear firm Crocs has announced that Russell C Hammer has resigned as its chief financial officer effective 31 December 2010.

Hammer is to join a Chicago based public company as its chief financial officer, and Crocs said a search for his successor was underway.

President and chief executive officer, John McCarvel, said: "I want to thank Russ for his many contributions and wish him well in his new role and location closer to his family. Looking forward, we are excited about both our near- and long-term growth prospects and I am very confident that the financial team we have in place is up to the task of managing the CFO responsibilities until a successor is found."
