After you file

Thank you so much. Let me provide most updated information:  I was recently informed that the company has closed and filed form 966 "Corporate Dissolution or Liquidation" - do I need to report anything to IRS because of that? So, in 2015 I was given stock which has been vesting over the period of 2 years which technically didn't end yet but the company has already been closed...
Should I expect anything sent to me by the company for a purposes of reporting with my taxes for the year 2016 because I was given those stocks?
