I don't think they are. The character is over-encumbered, so I don't need to worry about dexterity bonus, but plate mail is AC 3, plate mail and shield is AC 2. There are also: +2 for the magic part of the platemail +2 for the magic part of the shield +2 for whatever cloak he has +1 for Dwarf Booties of some sort +1 for a ring. That adds up to 8, or -8 from the AC which should be AC -6 How does the sheet get -9?
