Starting AC for a Dragon?

[Denim N Leather]

I am statting out a few dragons for my current homebrew campaign and cannot see where the starting AC is for a dragon in their base stats; in Bestiary 1, it clearly states their Natural Armour bonus, but not the base AC, that I can see.

Any assistance would be appreciated.

Thanks!

Base AC for all creatures is 10. Everything else is a modifier, whether it be natural armor, shield, deflection, dodge, size, etc.
