Where the information is sufficient only to establish a range of probable liability, and no point within the range is more likely than any other, it is the Company’s policy to accrue the lower end of the range.

While the Company and many businesses generally have returned to normal operating practices, this remains an evolving situation. The timing for recovery of businesses and local economies, resurgences or mutations of the virus, and any potential future shutdowns remains unknown. Throughout the COVID-19 pandemic, the Company has continued to provide essential services to our customers. Both the Company and NJNG continue to have sufficient liquidity to meet their current obligations and business operations remain fundamentally unchanged at this time. The Company will continue to monitor developments affecting its employees, customers, and operations and take additional steps to address the COVID-19 pandemic and its impacts, as necessary. The Company considered the impacts of COVID-19 on the assumptions and estimates used and determined that there have been no material adverse impacts on the Company’s results of operations as of September 30, 2022.</span></div>
