Someone asked about this program. Now that it's public info, I can share limited details, see SEC filing for more info. Multi Year RSU is a program where you will be given 4 separate grants but all at once (each grant vest over 4 years). CA employees probably haven't dreamt of the numbers they will see in those grants - don't argue, take my word for it and thank me in early to mid Jan.
However, these are essentially golden handcuffs. If you survive, they are all yours... Key here is, you have to still do an assessment as to whether you can survive and if $$ is a motivating factor for you. Broadcom treatment of CA is no different than previous acquisitions (been there...), yet they have industry lowest turnover, think why ;)
For me personally, I went thru this 5 years ago, for whatever reason I took the risk, survived, and paid off 2 houses,,, I don't come to office to make a dent in the world, for me it's a means to an end. However, your mileage may vary :)
Though I will tell you this, looking at a huge $$ chunk sitting in your Fidelity account will be too tempting to walk away from - yet I urge you to do a pros/cons assessment, based on your risk profile. Still don't expect hugs from management, or other touchy feely perks, but simply sh*t load of money in the form of stocks and bonus. Based on my experience (biased view!), Broadcom gets bad name because CEO doesn't lie thru his teeth, he tells what he will do and he does it, as opposed to other CEOs, who are simply too nice, will say all the good things you want to hear, and same end result - you are still a number, Broadcom tells you that in your face, other CEOs make you "feel" otherwise and yet here you are....
Good luck to all and welcome to roller coaster named Broadcom.
