Goodwill [Abstract]
Goodwill	Note 4 – Goodwill The following table summarizes the changes in the Company’s goodwill, by business segment: Regulated Water Regulated Natural Gas Other ConsolidatedBalance at December 31, 2020 $ 58,659 $ 2,261,047 $ 4,841 $ 2,324,547Goodwill acquired - - - -Measurement period purchase price allocation adjustments - 16,400 - 16,400Reclassification to utility plant acquisition adjustment (111) - - (111)Balance at September 30, 2021 $ 58,548 $ 2,277,447 $ 4,841 $ 2,340,836 The measurement period purchase price allocation adjustments resulted from the completion of the Peoples Gas Acquisition on March 16, 2020, which resulted in goodwill of $2,277,447 which was subject to adjustment over the one year measurement period that ended on March 15, 2021. Refer to Note 3 – Acquisitions for information about the goodwill attributed to our Regulated Natural Gas segment. ‎ The reclassification of goodwill to utility plant acquisition adjustment results from a mechanism approved by the applicable utility commission. The mechanism provides for the transfer over time, and the recovery through customer rates, of goodwill associated with some acquisitions upon achieving specific objectives. Goodwill is not amortized but is tested for impairment annually, or more often, if circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount. When testing goodwill for impairment, the Company may assess qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, and entity specific events, for some or all of our reporting units to determine whether it’s more likely than not that the fair value of a reporting unit is less than its carrying amount. Alternatively, based on our assessment of the qualitative factors previously noted, we may perform a quantitative goodwill impairment test by determining the fair value of a reporting unit. If we perform a quantitative test and determine that the fair value of a reporting unit is less than its carrying amount, we would record an impairment loss for the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. The Company performed a quantitative assessment for its annual test of the goodwill attributable to its Regulated Natural Gas reporting unit as of July 31, 2021. We estimated the fair value of the reporting unit by weighting results from the market approach and the income approach. Key assumptions in the valuation methodologies for goodwill included growth rates, terminal value, discount rates, and comparable multiples from publicly traded companies in our industry. Based on our analysis, we determined that the fair values of our Regulated Natural Gas reporting unit exceeded their carrying values, indicating none of its goodwill was impaired. The Company performed a qualitative assessment for its Regulated Water and Aqua Resources reporting units as of July 31, 2021, and concluded that it is more likely than not that the fair value of each reporting unit, which has goodwill recorded, exceeded its carrying amount, indicating that none of their goodwill was impaired.
