Merrill Lynch - Not Totally Gone

We all know that Merrill Lynch has been bought over by the Bank of America. I don't really follow the financial news so I am not sure if the office in Singapore has shut down completely.
Anyway, I saw the Merrill Lynch sign up on a rooftop of a building when I was in the cable car from Sentosa to Mount Faber.

It is supposed to be hidden from public view (unless you get an aerial view like I did). I guess they have no idea what to do with the sign?

The things you can find up on roof tops.
