Item 2. Properties During 2019, we initiated a plan to consolidate and reduce the number of our facilities worldwide. This included plans to provide a new customer experience center for product demonstration and training, relocate and consolidate our laboratories, server farms and Cloud service infrastructure and condense research and development, sales, marketing, business operations and administrative functions into our new Plano campus. In February 2021, we relocated our corporate headquarters to our new 32 Table of Contents facility in Plano, Texas. We also lease smaller (under 50,000 square feet) office space in various countries around the world for sales, marketing, research and development/engineering, and customer services and support staff, as well as for warehouse purposes. We are exiting certain of these facilities. We believe our remaining facilities will be adequate for our current needs and that suitable additional space will be available as needed.
