Item 2. Properties

Our principal offices are located at 400 South LaSalle Street, Chicago, Illinois 60605. Through our wholly-owned subsidiary, Cboe Building Corporation, we own the building in which our principal offices are located and occupy approximately 300,000 square feet of this building.

In addition to our principal offices, we have space located at 8050 Marshall Drive, Lenexa, Kansas, where we lease approximately 61,900 square feet of space. The lease on this space expires in February 2027 and contains two five-year renewal options, as well as a one-time option to terminate in November 2019 if certain contingencies under the lease are met. We have an office located at 17 State Street, New York, New York, where we lease approximately 21,000 square feet of space, which expires in April 2024, and contains one five-year renewal option. The disaster recovery sites in the United States are located in Kansas City, Missouri and Secaucus, New Jersey. In addition, we have agreements with a primary data center in Secaucus, New Jersey and a secondary data center in Chicago, Illinois. Our principal offices in the United Kingdom are at 11 Monument Street, London, where we lease approximately 10,300 square feet of office space, which expires in March 2027. Our work area recovery space is available on invocation with a specialist provider. In Europe, our primary data center is in Slough, England. The secondary data center for Cboe Europe is in Park Royal, London. We operate a back-up location for our London operations in the United Kingdom. We also maintain leased locations in California, Florida, Singapore, Amsterdam, and Hong Kong.

We believe that our properties are in good operating condition and adequately serve our current business operations. Generally, our properties are not earmarked for use by a particular segment. Instead, most of our properties are used by two or more segments. We also anticipate that suitable additional or alternative space will be available at commercially reasonable terms for future expansion to the extent necessary.
