español al inglés Negocios/Finanzas Finanzas (general)

Here is the sentence I need to translate:

vTRANSMISION DE PROPIEDAD Y EXTINCION TOTAL DE FIDEICOMISIO, QUe CELEBRAN: BANCO NACIONAL DE MEXICO, S.A., INSTITUCION DE BANCA MULTIPLE, GRUPO FINANCIERO, DIVISION FIDUCIARIA (COMO FIDUCIARIO) LOS SEnORES ...

I figure it's "Banco Nacional de México, a full-service banking institution", but is it the financial group, fiduciary division (as the fiduciary) - or rather, trusteeship division (as the trustee), Mr. and Mrs.... X ... who are entering into the agreement? Could someone who understands banking help me? Who is the trustee? No son los señores X - y si es así, ¿qué tiene que ver el "grupo financiero"?

Thanks in advance,
