If I remember correctly, BV is now about $0.35 per share? So, P/BV is about 0.8.
The low hanging fruit is now gone. My guess is, there is still 20-50% upside left.
I looked through my notes. In FY15, it was trading at NACV at one point. All PPE were free! In hindsight, I should've taken an even bigger position. LOL.
