German to English Law/Patents Real Estate

Hello,

This is from an office stamp in a real estate case in regard to a commercial lease in Switzerland:

I would assume this to be the lessee's rubber stamp, but I am not completely sure. The lessee is a company.

Kfz.
WE-I
WE-A
***ALV***
GWG
Wbg.
BM
GEPR.
ERL.

GWG is Gemeinnützige Wohn- und Siedlungsgesellschaft.
Wbg. is Wohnungsbaugenossenschaft.
Kfz, BM, ALV, WE-I and WE-A are currently unknown.
ALV might be Arbeitslosenversicherung, but how would that make sense here? Alleinvertretung? There is an agent involved.
GEPR.(üft)
ERL.(edigt)

Cheers,

Sebastian Witte
