Will my whole share for that company be counted as loss?

I backtested my very simple low PE strategy and it recorded pretty impressive CAGR of 58.6% for 20 years of backtest period. (But fitness score is only 2.2. I don't know how to improve this score. ;-P) 

I wonder if there were companies that were delisted in the backtest period and how it was handled by QC.
