They are financial "wizards" looking at giant Excel spreadsheets in a land far away. Your boss doesn't have much say except to execute an order flowed to him. He gets a number and has to let that many go. I have also seen entire groups get the axe at one time.
So hopefully you are in the right group or your number doesn't come up, assuming you want to stay. All the people I worked with were also great people and very nice, but no affect on whether you stay or go.
