Commitment to the Environment, Social, and Governance Framework Mimecasters recognize that our commitment to global community resilience will only succeed with an equally robust commitment to protecting our environment and the conservation of natural resources. We remain committed to measuring, mitigating, and reducing our carbon footprint through energy efficiency measures at each of our facilities. We must fully comply with applicable environmental laws and regulations, including those related to recycling and the disposal of wastes. We expect third parties with which we partner to share these commitments. Mimecast is committed to supporting the communities in which we work and live. Although we work tirelessly to deliver cyber resilience more cost effectively, more simply, and more comprehensively than any other vendor by innovating through cloud technology, we also work to build more resilience in our world together through corporate donations, employee gift matching, and volunteerism. We publish our Modern Slavery Act Disclosure Statement to demonstrate our commitment to supporting and promoting human rights in our supply chain and in the communities in which we live and operate. Mimecast has implemented key governance policies designed to demonstrate and enforce our commitment to supporting the resilience of our global community. Questions?
