Who could buy it? The only apparent contenders would be Intel, TSMC, GloFo or Samsung.
However, while Intel has cash of $20 billion, it has debt of $13 billion and may not be in a position to acquire it.
TSMC says it doesn't want to operate foreign fabs.
GloFo's owners are said to be getting impatient with the company.
So that leaves Samsung which gets its core technology from IBM under the Common Platform Alliance and uses that technology to successfully manufacture in the USA.
The big question now is: what will happen to the Common Platform Alliance?
Other companies which get their core process technology from IBM under the Common Platform Alliance are: GloFo, UMC, ST, Renesas, NEC, Frrescale, Toshiba and Infineon.
It is thought that IBM sold about $1.75 billion worth of semiconductors for a loss of $130 million last year and will lose about the same this year on revenues of $1.45 billion.
