Yahoo is in the process of reorganizing and trying once more to reinvigorate its core advertising, search, and services businesses.  However, challenges for the company remain as it continues to trail Google in market share.

This week it was revealed that Yahoo Inc. Chief Financial Officer Blake Jorgensen will be leaving the company.  Mr. Jorgensen will be just the latest in a string of high profile departures, starting with former CEO and Yahoo cofounder Jerry Yang's departure and the takeover of Carol Bartz as CEO six weeks ago.

Yahoo is currently in the hunt for a new CFO.  In the meantime, Mr. Jorgensen will stay onboard to aid in the transition.  The move was discovered in U.S. Securities and Exchange Commission filings.

Mr. Jorgensen attended Stanford University and received his M.B.A. from Harvard University in 1988.  He then worked in the finance industry for many years, working as Co-Director of Investment Banking at Thomas Weisel Partners from 2002 to 2007.  Mr. Jorgensen joined Yahoo in 2007, and has been in charge of the company's finances ever since.

Mr. Jorgensen announced last Wednesday that Yahoo was open to selling just its search business.  This was precisely what Microsoft wanted to buy last year.   However, those times have come and gone and with Microsoft dealing with its own challenges, Yahoo now seems without any who particularly desires it -- in pieces or as a whole.
