American International Group's (AIG) property/casualty insurance headquarters building in lower Manhattan is nameless after the removal of the AIG logo from its facade, a spokeswoman said Tuesday.

AIG announced in early March that it had formed a new holding company named AIU Holdings Inc. for its worldwide property/casualty insurance operations. The name was taken from AIG's well-known international brand, American International Underwriters, but it isn't necessarily the name the company will settle on for marketing purposes, said Christine Pretto, an AIG spokeswoman.

For now, the building at 175 Water Street in lower Manhattan won't carry a signature name, Pretto said, as the company goes through the process of settling on what its marketing image will be.

AIG is currently in the process of breaking up its global insurance and financial services businesses to repay its goverment bailout loans.
