@mkm is fully right. This company has 30000 employees, 15000 only in SD, say in California. They have fired 1500 here in this round in this state. Take a look at the thread @SMTpXbN. Some employee said 85% of CPU team in Austin has been vaporised. Very rough estimate: If there are, say, 20000 employees in US, and if you extrapolate through the numbers in California only, then it is around at least 2000+ in this round. So, about 500 employees have not been reported officially yet. This is roughly 25% of this round's head cut.
For 1B$ cost saving even with unreported numbers, say, 2000 is not enough to survive. More are coming!!!
