Google, Facebook in talks with Twitter

Google and Facebook have held “low level” takeover talks with Twitter that values the social networking firm as high as $10 billion, it was reported yesterday.

According to the Wall Street Journal, executives at Twitter have held talks with executives at Facebook and Google in recent months about a possible takeover of the micro-blogging site.

Citing people familiar with the matter, the newspaper said other companies have also held similar talks.

“But what’s remarkable is the money that people familiar with the matter say frames the discussions with at least some potential suitors; an estimated valuation in the neighbourhood of $8 billion to $10 billion,” it said.

The paper said the talks have gone nowhere and that Google, Facebook and Twitter all declined to comment.

"The significant potential of this discovery, up-dip of Jubilee, will be appraised during 2011 and 2012 once the current drill-out campaign has been completed."

US jobless claims fall to 2½-year low

New US claims for unemployment benefits dropped to a two-and-a-half year low last week, offering assurance that the labour market was strengthening, despite January's poor jobs numbers.

Initial claims for state unemployment benefits fell 36,000 to a seasonally adjusted 383,000, the lowest since early July 2008, the Labour Department said.

"Anecdotally, we do hear that there is some improvement on the jobs front and this is another indication of that," said Tim Ghriskey, chief investment officer at Solaris Asset Management in New York.

A Labour Department official said claims were still unwinding some of the weather effects that pushed up applications last month.

The four-week moving average of unemployment claims fell 16,000 last week.
