AC. - Asociacion Nacional del Notariado Mexicano, a.c.

[k2bdx]

I'm translating a document from Mexico. There is a label on the document, which says "Asociacion Nacional del Notariado Mexicano, a.c."
I'm guessing that the a. means Asociacion, but what does the c. mean?
Gracias de antemano...

Probably means Asociación Civil. Let's wait from a Mexican forero to confirm, but I'm 99% sure.
