CHICAGO (CBS) —  The former John Hancock building could be getting its old name back.

Real estate firm Sterling Bay had a contract to buy the building at 875 N. Michigan Ave. for more than $300 million. The company removed the John Hancock name from the building earlier this year.

But Sterling Bay now says the deal has been terminated.

That means the 100-story skyscraper and its naming rights are back in the hand of longtime owner Hearn Company.
