In a regulatory filing with the US Securities and Exchange Commission on Thursday, Yahoo! said Jorgensen would be leaving the firm and added that the search has started for a new CFO.
Jorgensen would remain with the company as the CFO through a transition period, the filing added.
The development comes amid reports suggesting that the newly appointed Yahoo! chief Carol Bartz would soon be announcing a corporate reorganisation of the company.
Bartz took over the reins of the internet major in January.
On the other hand, Yahoo! India's CEO for Research & Development (R&D) Sharad Sharma has decided to quit the company.
Sharma would be replaced by Shoubick Mukherjee as the new R&D head.
Shares of Yahoo! closed at 12.98 dollars on the Nasdaq on Thursday.
