Does armor penetration have a limit?

I know ( or at least I think I know) that armor pen works by:

(Armor - Armor Pen.) / (Armor + 100) [Correct me if I'm wrong pls]

So what if you get negative armor form armor pen., what does that mean?

ex. Base Amor is 20.
Armor Pen. is 25

Without Armor Pen. damage reduction is:
(20) / (120) = 16.7%

With Armor Pen. damage reduction is:
(-5) / (120) = -4.2%

Do you take extra damage?

Please correct me if I'm wrong with my concept and please don't link me to the FAQ page cause the discussion on Armor Pen. is not clear.

yeah you will take more damage but then again...
i played on corki with 2-3 black cleavers.
i went to dragon, gattling gun, and started hitting dragon, dragon had large amount of negative armor. did 400+ damage with base damage of 300.
i would safely assume yes.

Armor Penetration can't reduce it below 0.

Armor Reduction can.

In your example, it becomes 0%.
