Related Party Transactions [Abstract]

RELATED PARTY TRANSACTION

On December 28, 2016, we entered into a sublease for portions of our office space at 600 West Chicago to Uptake, Inc. ("Uptake"), a Lightbank LLC ("Lightbank") portfolio company. Eric Lefkofsky, our co-founder and Chairman of the Board, is a co-founder and owns a significant equity interest in Lightbank. The sublease was a market rate transaction on terms that we believe are no less favorable than would have been reached with an unrelated third party. The sublease extends through January 31, 2026 and sublease rentals over the entire term total approximately $18.2 million. Pursuant to our related party transaction policy, our Audit Committee approved the sublease. We recognized income from the sublease of $2.1 million, $2.1 million and $1.9 million for the years ended December 31, 2019, 2018 and 2017.
