This begins with addressing climate change by achieving net-zero carbon emissions for the Company’s operations and through its value chain by no later than 2030 UPC supports communities through various initiatives intended to give back and promote goodwill. UPC has provided support to numerous non-for-profit organizations over the past several years that champion noble causes including youth education, work force development, medical care/research, domestic violence shelters / prevention, child-care services, and many others Governance UPC is committed to increase the representation of women, people of color, and other underrepresented groups on its Board and Management Team. UPC’s goal is to add at least two new Directors to its Board over the next couple of election cycles to improve overall diversity at the highest level of corporate governance UPC will increase its capital allocated toward ESG focused investment vehicles and opportunities from 0% up to 10% of total stockholders’ equity attributable to UIHC stockholders. This is one of the most powerful ways an insurance company like UPC can drive progress by doing its part to ensure capital is more available and cost effective to those who practice sustainability Trust Accountability Integrity Persistence Teamwork Bias to Action
