On February 12, 2018, John Hancock Insurance requested that its name and logos throughout the building’s interior be removed immediately; John Hancock had not had a naming-rights deal with the skyscraper's owners since 2013. Until a new naming-rights deal is finalized, the skyscraper will be known as "875 North Michigan Avenue".
