I was a Fluor employee and stockholder in 2000 when Fluor divested itself of Massey Energy. I have several years of 401k forms showing ownership of Massey stock. Then nothing. What happened to my stock?
Massy was purchased by Alpha Natural Resources (ANR). I think they issued stock.
You should now have ANR in your 401k, if not you were paid outright...and be glad cuz ANR on rough times.
Massey Energy was purchased by another company, I think in 2011. You were probably paid for your stock at that time. You can probably get more details by searching for Massey Energy in Wikepedia.
