The Company relies extensively on computer systems to manage its business, including to provide services to Curbline Properties and the Company's joint ventures. While the Company maintains some of its own critical information technology systems, it also depends on third parties to provide important information technology services relating to several key business functions, such as payroll, human resources, electronic communications and certain finance functions. These systems are subject to damage or interruption from power outages, facility damage, computer or telecommunications failures, computer viruses, security breaches, vandalism, natural disasters, catastrophic events, human error and potential cyber threats, including phishing attacks, ransomware and other sophisticated cyber-attacks. Although the Company and such third parties employ a number of measures to prevent, detect and mitigate cyber threats, including password protection, firewalls, backup servers, threat monitoring and periodic penetration testing, the techniques used to obtain unauthorized access change frequently and there is no guarantee that such efforts will be successful. Should they occur, these threats could compromise the confidential information of the Company's tenants, employees, third-party vendors, joint ventures and other counterparties (including Curbline Properties); disrupt the Company's business operations and the availability and integrity of data in the Company's systems; and result in litigation, violation of applicable privacy and other laws, investigations, actions, fines or penalties. In the event of damage or disruption to the Company's business due to these occurrences, the Company may not be able to successfully and quickly recover all of its critical business functions, assets and data. Furthermore, while the Company maintains insurance, the coverage may not sufficiently cover all types of losses, claims or fines that may arise. For additional information see Item 1. "Business-Information Technology and Cybersecurity" in Part I of this Annual Report on Form 10-K.
