Item 2. Properties

We lease office space facilities for our corporate headquarters in Norwalk, Connecticut, United States of America. We lease additional space, including office space and data center facilities in various locations around the world, to support our operations, the largest being the headquarters of our Booking.com business in Amsterdam, Netherlands. Other than the office building for the future headquarters of the Booking.com brand that is currently under construction in the Netherlands and the associated land-use rights (see the section "Land-use rights" within Note 2 to our Consolidated Financial Statements for more details, which is incorporated into this Item 2 by reference thereto), we did not own any real estate at December 31, 2018.

We believe that our existing facilities are adequate to meet our current requirements, and that suitable additional or substitute space will be available as needed to accommodate any further expansion of corporate operations.
