Certara, Inc. 10-K

Item 2. Properties. As of December 31, 2020, we had 45 offices in 14 countries, with our headquarters located in Princeton, New Jersey. We lease or sublease all of our offices. None of our facilities are used for anything other than general office use. We believe that our facilities are adequate for our operations and that suitable additional space will be available when needed. Because of the COVID-19 pandemic, in March 2020, we temporarily closed all of our offices. As of December 31, 2020, the majority of our offices remained closed, and we have instituted a protocol for assessing the need to re-open any facilities and determining what safety measures are required or recommended by local health authorities to re-open such facilities. For the few offices that we have re-opened, we maintain the required safety measures, and strictly limit the number of employees who may be in an office at any time. We believe our employees have been able to maintain 48 Table of Contents the same level of productivity in a remote working environment as they did prior to the pandemic. We expect that most of our offices will re-open in some capacity once the current pandemic has abated. As of December 31, 2020, our material operating locations, which we define as the facilities we lease with more than 10,000 square feet, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ APPROXIMATE ​ LEASE EXPIRATION LOCATION SQUARE FOOTAGE DATES Wilmington, Delaware, USA ​ 18,250 ​ 2/28/2027 Princeton, New Jersey, USA 17,560 6/30/2025 Makati, Philippines 16,710 10/31/2022 Sheffield, UK 13,910 1/28/2028 Raleigh, North Carolina, USA 11,560 2/28/2022 ​ ​
