NEW YORK, NY - NOVEMBER 30: The Empire State Building, one of the world's most iconic buildings, is viewed on November 30, 2011 in New York City. Malkin Holdings LLC., the family-owned company that supervises the portfolio of office properties that includes the Empire State Building, has filed notice with the Securities and Exchange Commission acknowledging that it may become a publicly traded company. The filing could pave the way for an Initial Public Offering, or IPO, thus making the Empire State Building part of a publicly traded real estate investment company.
