Which entity are you speaking to questioner?
The DU-North America origins can be found here:

As to the DU-Philippines, they have no 'national' origins, they do not consider themselves as a national organization, merely as chapters of Delta Upsilon International Fraternity. If you want info on their chapters, check out one of their websites (posted earlier many times)
Hope this helps...
