Determining my Eidolon's AC Bonus

[hangarflying]

Hello everyone,

My summoner is 2nd level, and the eidolon has 2 HD. HL says my eidolon's AC is 18, and gives me an AC breakdown of +2 Dex, +6 natural. From what I can calculate, I should have:

+2 Dex
+2 natural (from the quadruped base form)
+2 natural (from the improved natural armor evolution)

I cannot, for the life of me, think of where I'm getting the extra +2 natural armor. Any ideas where I can look to find that?

APG pg. 59 - table 2-9 - eidolons get an armor bonus as their summoner levels. It's +2 at 2nd level.

DOH! I read that too and forgot to include it in my mental calculations. I guess I need to write things down! Thanks!
