This is the quote:
"I don't see any scenario where they're responsible for less than 10% of the value destruction, so around $4 billion."
In my head, he is comparing the minimum size of ADLs value reduction to be 10% or 4 billion. 10% of 44 billion is 4,4 billion. In this comment he is not saying anything about the current value except that 10% of 44 is around 4.
How else can you read it?
