[Bushido19]

First of all, the word doesn't exist. It's an aberration of the Spanish language has been popularized mainly by banks ("Aperturar" una cuenta bancaria").

The action of the verb "Abrir" (To Open) is "Apertura" (Opening). There is no need to get creative and make a new verb "Aperturar" (Openingen?). I was really surprised to find that word in your dictionary, conjugated and the whole nine yards.

Moreover, the three links you have on the bottom (Look up aperturar on RAE.es, Look up aperturar on MerriamWebster.com, Look up aperturar on Dictionary.com) gives you as a result "The word "aperturar" is not in the dictionary".
