Actual results could differ from these estimates, assumptions and judgments. The Company considers its critical accounting estimates to include (i) the application of regulatory accounting principles and the related determination and estimation of regulatory assets and liabilities, (ii) assumptions used in impairment testing of goodwill and long-lived assets, including regulatory assets, (iii) revenue recognition and the estimates used in the calculation of unbilled revenue, (iv) accounting for income taxes and the enacted Tax Cuts and Jobs Act (the “TCJA”), (v) benefit plan assumptions and (vi) the estimates and judgments used in determining loss contingencies. The Company’s critical accounting estimates that are particularly sensitive to change in the near term are amounts reported for regulatory assets and liabilities, goodwill, income taxes, benefit plan assumptions and contingency-related obligations.</font></div></div>
