PD retention based on first time approval?

[pzb01]

Dear All,

I am going thru a situation where my first I140- EB2 is approved around Feb 2012 thru company A , this is active for a long period and withdrawn in OCT 2015 . After it gets withdrawal , company B got me an approved I140-EB2 on July 2016 with PD retention. 

Now I moved to company C on NOV-2016 . Company C has started my GC filings . If Company B withdraw my I 140 immediately , still my 2012 PD from first employer retains? Please advice ..
