That is normal for all sorts of financial organizations, to not put the name on an office building. If they do, they get customers wandering into the lobby thinking it's a retail branch looking for services. Bigger problem for banks, but investment firms get that too. I once worked for Citibank in an owned but unlabeled building.

Basically it's the same reason that Wal-Mart doesn't put its name on a distribution warehouse facility. People would try to walk in thinking it's a store.
