<prompt> Human: A previous employer small, private company provided me with stock certificates. I quit a little over a year ago and they have reached out asking if Id be willing to sell the stock back. I am willing. They indicated that the first step is a phone call with the CEO to discuss. Anyone gone through this before and have some advice about what I should expect? Im assuming the CEO would like to buy them back for as little as possible and has little incentive otherwise. Am I wrong about this?  <response>: Check your employment contract first.
