This is just my guess - my guess is originally everyone thought we need to make $2 for 90 days...then when we fell below $2, gnbt must have consulted Donohoe and nasdaq and they must have done some research and told Gnbt that the application was still ok because we met 90 days of $2 in 2017 and 2018...also it makes sense to me that the PPS they look at is before the split.

Just a guess.
