Encumbered and Overburdened Question

[Furansisuco]

In the Pag 157 i have the rules for Encumbered and Overburned, but a have a question
encumbered - take a –5 penalty to Strength- and Dexterity-based checks.
Overburdened - take a –5 penalty to Strength- and Dexterity-based checks.
This penaltys are stackable?

I know the AC and movement speeds penalty.

They are untyped, so mechanically they should stack fine. And logically, they ought to stack.
