Yes, your account should contain a balance based on the final buyout price of the stock, minus any maintenance fees.
I had 100 Shares of Toys R Us stock in a Sharebuilder account. I haven't logged on in 10+ years. They are down for maintanence so I can't check until morning. Anyways, Toys R Us was bought out in 2006. Does that mean I'll have cash in my account?
