Want a piece of the Empire State Building? You may soon be able to have one.

DealBook reports that the owner of the building, the Malkin family, has included the New York City skyscraper in a new I.P.O. filing aimed at simplifying its sprawling real estate holdings. The landmark is the crown jewel of the offering that includes shares in 12 buildings in New York and Connecticut.

The move will allow the Malkins to convert the equity held by other investors into stock in the new company, Empire State Realty Trust.
