Re: ASA chapter absorption
 

In my experience living through corporate mergers, there's really no such thing. Somebody wins and somebody loses. I highly doubt that if a big NPC sorority "merged" with a small sorority there would be any combining of ritual, colors, whatever. They might take that opportunity to change their logo or mascot or something, but that would really just be to update or get rid of something nobody liked anyway. Or as in the example of a certain bank I used to do travel for, they took a perfectly good logo and made it into a godawful one, even though it STILL didn't accommodate any of the other bank's image.

And I believe they share one other campus.

I determined that it was definitely the AST/Pi Phi combination that I had discovered a couple years ago, with Pi Phi recently colonizing at NYU.

And AST only shares 1 or 2 campuses with ADPi, AEPhi, and Theta as well.

Corporations and sororities are two vastly different things.

If giant NPC group XYZ merged with teeny regional group ABC and basically screwed ABC over, the ABC alumnae (in this day & age of the internet) could really make XYZ's name mud.

In the case of the bank you cited, most people, even if they don't like the new "image" probably stayed with it just becuase it's more of a pain in the ass to change than it is to stay where you are. Sororities aren't like that. If someone goes into rush and has seen a zillion things about how XYZ is a bunch of jerks, it's going to affect her opinion. If it effects enough people's opinions, XYZ will suffer in membership numbers and revenue.

Based on what 33 said, there have been fraternity mergers in the past which have done a lot to try to keep aspects of both alive. Lambda Chi Alpha comes to mind.

Exactly the one I was thinking of. Aspects of Theta Kappa Nu's arms, including its motto, were incorporated into Lambda Chi's arms, its badge was incorporated into Lambda Chi's associate member pin, and its rituals became (with some condensation and adaption) Lambda Chi's associate member ceremony.

I know that some groups, when they've absorbed locals, have used the local's letters as the chapter designation.
