401(k) not fully vested at time of acquisition
Unfortunately, the money that is not vested is not yours.  It belongs to your employer.  They have promised to give it to you after you have been with the company for a certain length of time, but if you aren't still with the company after that time, no matter what the reason, the money never becomes yours. Sorry to hear about this.  It would have been nice if your company had waived the vesting requirement like this guy's employer did, but I don't think they are required to do so, unfortunately. If it's a lot of money, you could ask an attorney, but as @JoeTaxpayer said, AT&T and IBM probably know what they are doing.
