Basis Of Presentation [Abstract]
Basis Of Presentation	Note 1 – Basis of Presentation The accompanying unaudited consolidated balance sheets and statements of capitalization of Essential Utilities, Inc. and subsidiaries (collectively, the “Company”, “we”, “us” or “our”) at March 31, 2022, and the unaudited consolidated statements of operations and comprehensive income, of cash flows, and of equity for the three months ended March 31, 2022 and 2021, have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim reporting and the rules and regulations for reporting on Quarterly Reports on Form 10-Q. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. Interim results are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, consisting of only recurring accruals, which are necessary to present a fair statement of its consolidated balance sheets, consolidated statements of equity, consolidated statements of operations and comprehensive income, and consolidated cash flow for the periods presented, have been made. The preparation of financial statements often requires the selection of specific accounting methods and policies. Further, significant estimates and judgments may be required in selecting and applying those methods and policies in the recognition of the assets and liabilities in its consolidated balance sheets, the revenues and expenses in its consolidated statements of operations and comprehensive income, and the information that is contained in its summary of significant accounting policies and notes to consolidated financial statements. Making these estimates and judgments requires the analysis of information concerning events that may not yet be complete and of facts and circumstances that may change over time. Accordingly, actual amounts or future results can differ materially from those estimates that the Company includes currently in its consolidated financial statements, summary of significant accounting policies, and notes. In the preparation of these financial statements and related disclosures, we have assessed the impact that the COVID-19 pandemic has had on our estimates, assumptions, forecasts, and accounting policies. Because of the essential nature of our business, we do not believe the COVID-19 pandemic had a material impact on our estimates, assumptions and forecasts used in the preparation of our financial statements, although we continue to monitor this closely. As the COVID-19 pandemic is continuing to evolve, future events and effects related to the COVID-19 pandemic cannot be determined with precision, and actual results could significantly differ from our estimates or forecasts. There have been no changes to the summary of significant accounting policies previously identified in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Revenues from Contracts with Customers – These revenues are composed of four main categories: water, wastewater, natural gas, and other. Water revenues represent revenues earned for supplying customers with water service. Wastewater revenues represent revenues earned for treating wastewater and releasing it into the environment. Natural gas revenues represent revenues earned for the gas commodity and delivery of natural gas to customers. Other revenues are associated fees that relate to our utility businesses but are not water, wastewater, or natural gas revenues. Refer to the description below for a discussion of the performance obligation for each of these revenue streams.

Tariff Revenues – These revenues are categorized by customer class: residential, commercial, fire protection, industrial, gas transportation, other water and other wastewater. The rates that generate these revenues are approved by the respective state utility commission, and revenues are billed cyclically and accrued for when unbilled. The regulated natural gas rates are set and adjusted for increases or decreases in our purchased gas costs through purchased gas adjustment mechanisms. Purchased gas adjustment mechanisms provide us with a means to recover purchased gas costs on an ongoing basis without filing a rate case. Other water and other wastewater revenues consist primarily of fines, penalties, surcharges, and availability lot fees. Our performance obligation for tariff revenues is to provide potable water, wastewater treatment service, or delivery and sale of natural gas to customers. This performance obligation is satisfied over time as the services are rendered. The amounts that the Company has a right to invoice for tariff revenues reflect the right to consideration from the customers in an amount that corresponds directly with the value transferred to the customer for the performance completed to date.

Other Utility Revenues – Other utility revenues represent revenues earned primarily from: antenna revenues, which represents fees received from telecommunication operators that have put cellular antennas on our water towers; billing contracts, which represent fees earned from municipalities for performing billing services; fees earned from developers for accessing our water mains; miscellaneous service revenue from gas distribution operations; gas processing and handling revenue; sales of natural gas at market-based rates and contracted fixed prices; sales of gas purchased from third parties; and other gas marketing activities. The performance obligations vary for these revenues, but all are primarily recognized over time as the service is delivered.

Alternative Revenue Program:

Water / Wastewater Revenues: These revenues represent the difference between the actual billed utility volumetric water and wastewater revenues for Aqua Illinois and the revenues set in the last Aqua Illinois rate case. In accordance with the Illinois Commerce Commission, we recognize revenues based on the target amount established in the last rate case, and then record either a regulatory asset or liability based on the cumulative annual difference between the target and actual amounts billed, which results in either a payment from customers or a refund due to customers. The cumulative annual difference is either refunded to customers or collected from customers over a nine-month period.

Natural Gas Revenues: These revenues represent the weather-normalization adjustment (“WNA”) mechanism in place for our natural gas customers served in Kentucky. The WNA serves to minimize the effects of weather on the Company’s results for its residential and small commercial natural gas customers. This regulatory mechanism adjusts revenues earned for the variance between actual and normal weather and can have either positive (warmer than normal) or negative (colder than normal) effects on revenues. Customer bills are adjusted in the December through April billing months, with rates adjusted for the difference between actual revenues and revenues calculated under this mechanism billed to the customers.

These revenue programs represent a contract between the utility and its regulators, not customers, and therefore are not within the scope of the Financial Accounting Standards Board’s (“FASB”) accounting guidance for recognizing revenue from contracts with customers.

Other and Eliminations – Other and eliminations consist of our non-regulated market-based revenues and intercompany eliminations for revenue billed between our subsidiaries. Our non-regulated operations consist of utility service line protection solutions and repair services to households and gas marketing and production activities. Revenues are primarily recognized over time as service is delivered.

Acquisitions [Abstract]

Acquisitions

Note 3 – Acquisitions

Water and Wastewater Utility Acquisitions - Completed

In March 2022, the Company acquired the wastewater system of Lower Makefield Township, which serves approximately 11,000 customer connections in Lower Makefield, Falls and Middletown townships, and Yardley Borough, Bucks County, Pennsylvania, for a cash purchase price of $53,000.

In August 2021, the Company acquired the water utility system assets of The Commons Water Supply, Inc., which serves 992 customers in Harris County, Texas, and the wastewater utility system assets of the Village of Bourbonnais, which serves approximately 6,500 customers in Kankakee County, Illinois. The total cash purchase prices for these utility systems were $4,000 and $32,100, respectively.

The purchase price allocation for these acquisitions consisted primarily of acquired property, plant and equipment.

The pro forma effect of the utility systems acquired is not material either individually or collectively to the Company’s results of operations.

Water and Wastewater Utility Acquisitions – Pending Completion

In December 2021, the Company entered into a purchase agreement to acquire the water utility assets of the Southern Oaks Water System, which serves approximately 740 customers for $3,300. In October 2021, the Company entered into a purchase agreement to acquire the wastewater utility assets of the City of Beaver Falls, Pennsylvania which consists of approximately 7,600 customers for $41,250. In July 2021, the Company entered into a purchase agreement to acquire the water utility assets of Shenandoah Borough, Pennsylvania which consists of approximately 2,930 customers for $12,000. In April 2021, the Company entered into a purchase agreement to acquire certain water or wastewater utility assets of Oak Brook, Illinois which consists of approximately 4,000 customers for $12,500. In January 2021, the Company entered into purchase agreements to acquire, in separate transactions, the wastewater utility system assets of East Whiteland Township, Pennsylvania and Willistown Township, Pennsylvania which consist of approximately 10,500 customers for $72,400.

The purchase price for these pending acquisitions are subject to certain adjustments at closing, and are subject to regulatory approval, including the final determination of the fair value of the rate base acquired. We plan to finance the purchase price of these acquisitions by utilizing our revolving credit facility until permanent debt and common equity are secured. The closings of our acquisitions of East Whiteland Township, Willistown Township, and Oak Brook are expected to occur in the second half of 2022. The closings of our Shenandoah Borough, Beaver Falls, and Southern Oaks acquisitions are expected to occur in the first quarter of 2023. Closing for our utility acquisitions are subject to the timing of the respective regulatory approval processes.

DELCORA Purchase Agreement

In September 2019, the Company entered into a purchase agreement to acquire the wastewater utility system assets of the Delaware County Regional Water Quality Control Authority (“DELCORA”), which consists of approximately 16,000 customers, or the equivalent of 198,000 retail customers, in 42 municipalities in Southeast Pennsylvania for $276,500. In May 2020, Delaware County, Pennsylvania filed a lawsuit alleging that DELCORA does not have the legal authority to establish and fund a customer trust with the net proceeds of the transaction. In December 2020, the judge in the Delaware County Court lawsuit issued an order that (1) the County cannot interfere with the purchase agreement between DELCORA and the Company; (2) the County cannot terminate DELCORA prior to the closing of the transaction; and (3) the establishment of the customer trust was valid. Delaware County appealed this decision to Commonwealth Court of Pennsylvania. On March 3, 2022, the Commonwealth Court issued a decision finding that Delaware County can dissolve the Authority if it so chooses, but the purchase agreement must be upheld regardless of who is operating the system. The case was remanded back to the trial court for the entry of an order consistent with the Commonwealth Court’s opinion.

The administrative law judges in the regulatory approval process recommended that the Company’s application be denied, and subsequently, the Company provided exceptions to the recommended decision. On March 30, 2021, the Pennsylvania Public Utility Commission (“PUC”) ruled that the case be remanded back to the Office of Administrative Law Judge and vacated the original administrative law judges’ recommended decision (“2021 Order”). This 2021 Order was also appealed to the Commonwealth Court by Delaware County, and a decision is expected in the next several months.

After the PUC issued the 2021 Order, on April 16, 2021, the administrative law judge issued an order staying the proceeding until the Delaware County Court lawsuit is final and unappealable. On March 25, 2022, the Company sent a letter notifying the PUC of the March 3, 2022 Commonwealth Court decision and requested that the PUC move forward with processing the application. Several parties responded to the Company’s letter and referenced the issues in the second appeal before Commonwealth Court regarding the 2021 Order.

The purchase price for this pending acquisition is subject to certain adjustments at closing, and is subject to regulatory approval, including the final determination of the fair value of the rate base acquired. We plan to finance the purchase price of this acquisition by the issuance of common stock and by utilizing our revolving credit facility until permanent debt is secured. Closing of our acquisition of DELCORA is expected to occur in late 2022 or early 2023, subject to the timing of the regulatory approval process and Delaware County’s on-going litigation.

Note 4 – Goodwill

The following table summarizes the changes in the Company’s goodwill, by business segment:



	Regulated Water		Regulated Natural Gas		Other		Consolidated
Balance at December 31, 2021	$	58,527	$	2,277,447	$	4,841	$	2,340,815

Balance at March 31, 2022	$	58,527	$	2,277,447	$	4,841	$	2,340,815

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 or on a voluntary basis, 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.

Forward Equity Sale

In August 2020, the Company entered into a forward equity sale agreement for 6,700,000 shares of common stock with a third party (the “forward purchaser”). In connection with the forward equity sale agreement, the forward purchaser borrowed an equal number of shares of the Company’s common stock from stock lenders and sold the borrowed shares to the public. The Company did not receive any proceeds from the sale of its common stock by the forward purchaser until settlement of the shares underlying the forward equity sale agreement. The actual proceeds to be received by the Company would have varied depending upon the settlement date, the number of shares designated for settlement on that settlement date, and the method of settlement. The forward equity sale agreement was accounted for as an equity instrument and was recorded at a fair value of $0 at inception. The fair value was not adjusted as the Company continued to meet the accounting requirements for equity instruments.

On August 9, 2021, the Company settled the forward equity sale agreement in full by physical share settlement. The Company issued 6,700,000 shares and received cash proceeds of $299,739 at a forward price of $44.74 per share. Pursuant to the agreement, the forward price was computed based upon the initial forward price of $46.00 per share, adjusted for a floating interest rate factor equal to a specified daily rate less a spread and scheduled dividends during the term of the agreement. The Company used the proceeds received upon settlement of the forward equity sale agreement to fund general corporate purposes, including for water and wastewater utility acquisitions, working capital and capital expenditures. The forward equity sale agreement has now been completely settled, and there are no additional shares subject to the forward equity sale agreement.

Tangible Equity Units

On April 23, 2019, the Company issued $690,000, less expenses of $16,358, of its tangible equity units (the “Units”), with a stated amount of $50.00 per unit. This issuance was part of the permanent financing to close the Peoples Gas Acquisition.

Each Unit consisted of a prepaid stock purchase contract and an amortizing note, each issued by the Company. As of March 31, 2022, the balance of the stock purchase contracts was 7,603,234. During April 2022, 981,919 stock purchase contracts were early settled by the holders of the contracts, resulting in the issuance of 1,166,107 shares of the Company’s common stock. On May 2, 2022, the remaining 6,621,315 stock purchase contracts were settled for 1.18758 shares of the Company’s common stock for each stock purchase contract, and in aggregate the Company issued 7,863,354 shares of its common stock. The amortizing notes had an initial principal amount of $8.62909, or $119,081 in aggregate, and yielded interest at a rate of 3.00% per year, and paid equal quarterly cash installments of $0.75000 per amortizing note (except for the July 30, 2019 installment payment, which was $0.80833 per amortizing note), that constituted a payment of interest and a partial repayment of principal, and which cash payment in the aggregate was equivalent to 6.00% per year with respect to each $50.00 stated amount of the Units. The amortizing notes represent unsecured senior obligations of the Company. The final quarterly installment payment was made on May 2, 2022, which resulted in the complete pay-off of the amortizing notes.

Long-term Debt and Loans Payable

On April 15, 2021, the Company’s operating subsidiary, Aqua Ohio, Inc., issued $100,000 of first mortgage bonds, of which $50,000 is due in 2031 and $50,000 is due in 2051, with interest rates of 2.37% and 3.35%, respectively. The proceeds from these bonds were used for general corporate purposes and to repay existing indebtedness. Further, on April 19, 2021, the Company issued $400,000 of long-term debt, less expenses of $4,010, which is due in 2031, with an interest rate of 2.40%. The Company used the proceeds from this issuance to repay $50,000 of borrowings under the Aqua Pennsylvania revolving credit facility, and the balance was used to repay in full the borrowings under its existing five year unsecured revolving credit agreement.

Financial Instruments [Abstract]

Financial Instruments

Note 6 – Financial Instruments

The Company follows the FASB’s accounting guidance for fair value measurements and disclosures, which defines fair value and establishes a framework for using fair value to measure assets and liabilities. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:


l	Level 1: unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access;

l	Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted market prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in non-active markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or

l	Level 3: inputs that are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. There have been no changes in the valuation techniques used to measure fair value, or asset or liability transfers between the levels of the fair value hierarchy for the quarter ended March 31, 2022.

Financial instruments are recorded at carrying value in the financial statements and approximate fair value as of the dates presented. The fair value of these instruments is disclosed below in accordance with current accounting guidance related to financial instruments.

The fair value of loans payable is determined based on its carrying amount and utilizing Level 1 methods and assumptions. As of March 31, 2022 and December 31, 2021, the carrying amount of the Company’s loans payable was $79,743 and $65,000, respectively, which equates to their estimated fair value. The fair value of cash and cash equivalents, is determined based on Level 1 methods and assumptions. As of March 31, 2022 and December 31, 2021, the carrying amounts of the Company's cash and cash equivalents was $58,298 and $10,567, respectively, which equates to their fair value. The Company’s assets underlying the deferred compensation and non-qualified pension plans are determined by the fair value of mutual funds, which are based on quoted market prices from active markets utilizing Level 1 methods and assumptions. As of March 31, 2022 and December 31, 2021, the carrying amount of these securities was $27,282 and $28,576, respectively, which equates to their fair value, and is reported in the consolidated balance sheet in deferred charges and other assets.

Unrealized gain and losses on equity securities held in conjunction with our non-qualified pension plan is as follows:



	Three Months Ended

	2022		2021
Net gain (loss) recognized during the period on equity securities	$	(278)	$	248
Less: net gain / loss recognized during the period on equity securities sold during the period		-		-
Unrealized gain (loss) recognized during the reporting period on equity securities still held at the reporting date	$	(278)	$	248

The net gain (loss) recognized on equity securities is presented on the consolidated statements of operations and comprehensive income on the line item “Other.”

The carrying amounts and estimated fair values of the Company’s long-term debt is as follows:

The fair value of long-term debt has been determined by discounting the future cash flows using current market interest rates for similar financial instruments of the same duration utilizing Level 2 methods and assumptions.

The Company’s customers’ advances for construction have a carrying value of $104,403 as of March 31, 2022, and $103,619 as of December 31, 2021. Their relative fair values cannot be accurately estimated because future refund payments depend on several variables, including new customer connections, customer consumption levels, and future rates. Portions of these non-interest-bearing instruments are payable annually through 2032, and amounts not paid by the respective contract expiration dates become non-refundable. The fair value of these amounts would, however, be less than their carrying value due to the non-interest-bearing feature.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Net Income Per Common Share [Abstract]

Net Income Per Common Share

Note 7 – Net Income per Common Share

Basic net income per common share is based on the weighted average number of common shares outstanding and the weighted average minimum number of shares to be issued upon settlement of the stock purchase contracts issued under the tangible equity units. Diluted net income per common share is based on the weighted average number of common shares outstanding, potentially dilutive shares, and the expected number of shares to be issued upon settlement of the stock purchase contracts issued under the tangible equity units, based on the applicable market value of our common stock. The dilutive effect of employee stock-based compensation and shares issuable under the forward equity sale agreement (from the date the Company entered into the forward equity sale agreement to the settlement date) are included in the computation of diluted net income per common share. The dilutive effect of stock-based compensation and shares issuable under the forward equity sale agreement are calculated using the treasury stock method and expected proceeds upon exercise or issuance of the stock-based compensation and settlement of the forward equity sale agreement. The treasury stock method assumes that the proceeds from stock-based compensation and settlement of the forward equity sale agreement are used to purchase the Company’s common stock at the average market price during the period. The following table summarizes the shares, in thousands, used in computing basic and diluted net income per common share:



	Three Months Ended
	March 31,
	2022	2021
Average common shares outstanding during the period for basic computation	261,952	254,565
Effect of dilutive securities:
Forward equity sale agreement	-	3
Employee stock-based compensation	479	401
Average common shares outstanding during the period for diluted computation	262,431	254,969

For the three months ended March 31, 2022 and 2021, the average common shares outstanding during the period for basic computation includes the weighted-average impact of 9,029,461 and 9,091,179 shares, respectively, based on the minimum number of shares to be issued in April 2022 upon settlement of the stock purchase contracts issued in April 2019 under the tangible equity units.

For the three months ended March 31, 2022 and 2021, all of the Company’s outstanding employee stock options were included in the calculations of diluted net income per share as the calculated cost to exercise employee stock options was less than the average market price of the Company’s common stock during these periods. Additionally, the dilutive effect of performance share units and restricted share units granted are included in the Company’s calculation of diluted net income per share.

Stock-Based Compensation

Note 8 – Stock-based Compensation

Under the Company’s Amended and Restated Equity Compensation Plan (the “Plan”) approved by the Company’s shareholders on May 2, 2019, to replace the 2004 Equity Compensation Plan, stock options, stock units, stock awards, stock appreciation rights, dividend equivalents, and other stock-based awards may be granted to employees, non-employee directors, and consultants and advisors. The Plan authorizes 6,250,000 shares for issuance under the Plan. A maximum of 3,125,000 shares under the Plan may be issued pursuant to stock awards, stock units and other stock-based awards, subject to adjustment as provided in the Plan. During any calendar year, no individual may be granted (i) stock options and stock appreciation rights under the Plan for more than 500,000 shares of Company stock in the aggregate or (ii) stock awards, stock units or other stock-based awards under the Plan for more than 500,000 shares of Company stock in the aggregate, subject to adjustment as provided in the Plan. Awards to employees and consultants under the Plan are made by a committee of the Board of Directors of the Company, except that with respect to awards to the Chief Executive Officer, the committee recommends those awards for approval by the non-employee directors of the Board of Directors. In the case of awards to non-employee directors, the Board of Directors makes such awards. At March 31, 2022, 1,785,479 shares were still available for issuance under the Plan. No further grants may be made under the Company’s 2004 Equity Compensation Plan.

Performance Share Units – A performance share unit (“PSU”) represents the right to receive a share of the Company’s common stock if specified performance goals are met over the three year performance period specified in the grant, subject to exceptions through the respective vesting period, which is generally three years. Each grantee is granted a target award of PSUs and may earn between 0% and 200% of the target amount depending on the Company’s performance against the performance goals. The following table provides compensation expense for PSUs:



	Three Months Ended
	March 31,
	2022		2021
Stock-based compensation within operations and maintenance expenses	$	1,650	$	1,641
Income tax benefit		467		462

The following table summarizes the PSU transactions for the three months ended March 31, 2022:



	Number	Weighted
	of	Average
	Share Units	Fair Value
Nonvested share units at beginning of period	355,384	$	42.19
Granted	160,245		42.31
Forfeited	(3,161)		46.39
Nonvested share units at end of period	512,468		42.20

A portion of the fair value of PSUs was estimated at the grant date based on the probability of satisfying the market-based conditions using the Monte Carlo valuation method, which assesses probabilities of various outcomes of market conditions. The other portion of the fair value of the PSUs is based on the fair market value of the Company’s stock at the grant date, regardless of whether the market-based condition is satisfied. The per unit weighted-average fair value at the date of grant for PSUs granted during the three months ended March 31, 2022 and 2021 was $42.31 and $43.23, respectively. The fair value of each PSU grant is amortized monthly into compensation expense on a straight-line basis over their respective vesting periods, generally 36 months. The accrual of compensation costs is based on the Company’s estimate of the final expected value of the award and is adjusted as required for the portion based on the performance-based condition. The Company assumes that forfeitures will be minimal, and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the PSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the PSUs. The recording of compensation expense for PSUs has no impact on net cash flows.

Restricted Stock Units – A restricted stock unit (“RSU”) represents the right to receive a share of the Company’s common stock. RSUs are eligible to be earned at the end of a specified restricted period, which is generally three years, beginning on the date of grant. The Company assumes that forfeitures will be minimal and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the RSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the RSUs. The following table provides the compensation expense and income tax benefit for RSUs:



	Three Months Ended
	March 31,
	2022		2021
Stock-based compensation within operations and maintenance expenses	$	777	$	604
Income tax benefit		219		169

The following table summarizes the RSU transactions for the three months ended March 31, 2022:



	Number	Weighted
	of	Average
	Stock Units	Fair Value
Nonvested stock units at beginning of period	193,687	$	43.76
Granted	71,570		45.10
Stock units vested and issued	(54,079)		36.63
Forfeited	(653)		43.77
Nonvested stock units at end of period	210,525		46.08

The per unit weighted-average fair value at the date of grant for RSUs granted during the three months ended March 31, 2022 and 2021 was $45.10 and $44.44, respectively.

Stock Options – A stock option represents the option to purchase a number of shares of common stock of the Company as specified in the stock option grant agreement at the exercise price per share as determined by the closing market price of our common stock on the grant date. Stock options are exercisable in installments of 33% annually, starting one year from the grant date and expire 10 years from the grant date, subject to satisfaction of designated performance goals. The fair value of each stock option is amortized into compensation expense using the graded-vesting method, which results in the recognition of compensation costs over the requisite service period for each separately vesting tranche of the stock options as though the stock options were, in substance, multiple stock option grants. The following table provides the compensation cost and income tax benefit for stock-based compensation related to stock options:



	Three Months Ended
	March 31,
	2022		2021
Stock-based compensation within operations and maintenance expenses	$	100	$	211
Income tax benefit		28		60

The fair value of options was estimated at the grant date using the Black-Scholes option-pricing model. The following assumptions were used in the application of this valuation model:


	2022
Expected term (years)		5.48
Risk-free interest rate		1.92%
Expected volatility		26.50%
Dividend yield		2.37%
Grant date fair value per option	$	9.34

The Company did not grant stock options during the quarter ended March 31, 2021.

Historical information was the principal basis for the selection of the expected term and dividend yield. The expected volatility is based on a weighted-average combination of historical and implied volatilities over a time period that approximates the expected term of the option. The risk-free interest rate was selected based upon the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option.

The following table summarizes stock option transactions for the three months ended March 31, 2022:



		Weighted		Weighted
		Average		Average	Aggregate
		Exercise		Remaining	Intrinsic
	Shares	Price		Life (years)	Value
Outstanding at beginning of period	813,492	$	35.37

Exercisable at end of period	783,723	$	35.37	6.6	$	12,351,503

Restricted Stock – Restricted stock awards provide the grantee with the rights of a shareholder, including the right to receive dividends and to vote such shares, but not the right to sell or otherwise transfer the shares during the restriction period. Restricted stock awards result in compensation expense that is equal to the fair market value of the stock on the date of the grant and is amortized ratably over the restriction period. The Company expects forfeitures of restricted stock to be de minimis. The following table provides the compensation cost and income tax benefit for stock-based compensation related to restricted stock:

The following table summarizes restricted stock transactions for the three months ended March 31, 2022:

The Company did not grant restricted stock for the three months ended March 31, 2022.

Stock Awards – Stock awards represent the issuance of the Company’s common stock, without restriction. The issuance of stock awards results in compensation expense that is equal to the fair market value of the stock on the grant date and is expensed immediately upon grant. The following table provides the compensation cost and income tax benefit for stock-based compensation related to stock awards:

Rate Activity

Note 10 – Rate Activity

On January 3, 2022, the Company’s natural gas operating division in Kentucky received an order from the Kentucky Public Service Commission resulting in an increase of $5,238 in annual revenues, and new rates went into effect on January 4, 2022.

On August 20, 2021, the Company’s regulated water and wastewater operating subsidiary in Pennsylvania, Aqua Pennsylvania, filed an application with the Pennsylvania Public Utility Commission designed to increase rates by $97,685 or 17.9% on an annual basis. The Company anticipates a final order to be issued by May 2022.

Base rate cases are also underway for our water and wastewater utility operating divisions in Ohio.

During the first three months of 2022, the Company’s two other water utility operating divisions in Ohio were granted base rate increases designed to increase total operating revenues on an annual basis by $1,378. Further, during the first three months of 2022, the Company received approval to bill infrastructure rehabilitation surcharges designed to increase total operating revenues on an annual basis by $6,789 in its water and wastewater utility operating divisions in Pennsylvania, North Carolina, and Illinois.

Segment Information [Abstract]

Segment Information

Note 12 – Segment Information

The Company has twelve operating segments and two reportable segments. The Regulated Water segment is comprised of eight operating segments representing its water and wastewater regulated utility companies, which are organized by the states where the Company provides water and wastewater services. The eight water and wastewater utility operating segments are aggregated into one reportable segment, because each of these operating segments has the following similarities: economic characteristics, nature of services, production processes, customers, water distribution or wastewater collection methods, and the nature of the regulatory environment. The Regulated Natural Gas segment is comprised of one operating segment representing natural gas utility companies, acquired in the Peoples Gas Acquisition, for which the Company provides natural gas distribution services.

In addition to the Company’s two reportable segments, we include three of our operating segments within the Other category below. These segments are not quantitatively significant and are comprised of our non-regulated natural gas operations, Aqua Infrastructure, and Aqua Resources. Our non-regulated natural gas operations consist of utility service line protection solutions and repair services to households and the operation of gas marketing and production entities. Prior to the October 30, 2020 sale of our investment in joint venture, Aqua Infrastructure provided non-utility raw water supply services for firms in the natural gas drilling industry. Aqua Resources offers, through a third party, water and sewer service line protection solutions and repair services to households. In addition to these segments, Other is comprised of business activities not included in the reportable segments, corporate costs that have not been allocated to the Regulated Water and Regulated Natural Gas segments, and intersegment eliminations. Corporate costs include general and administrative expenses, and interest expense. The Company reports these corporate costs within Other as they relate to corporate-focused responsibilities and decisions and are not included in internal measures of segment operating performance used by the Company to measure the underlying performance of the operating segments. The Regulated Water and Regulated Natural Gas segments report interest expense that includes long-term debt that was pushed-down to the regulated operating subsidiaries from Essential Utilities, Inc.

The following table presents information about the Company’s reportable segments:

Commitments And Contingencies [Abstract]

Commitments And Contingencies

Note 13 – Commitments and Contingencies

The Company is routinely involved in various disputes, claims, lawsuits and other regulatory and legal matters, including both asserted and unasserted legal claims, in the ordinary course of business. The status of each such matter, referred to herein as a loss contingency, is reviewed and assessed in accordance with applicable accounting rules regarding the nature of the matter, the likelihood that a loss will be incurred, and the amounts involved. As of March 31, 2022, the aggregate amount of $16,577 is accrued for loss contingencies and is reported in the Company’s consolidated balance sheet as other accrued liabilities and other liabilities. These accruals represent management’s best estimate of probable loss (as defined in the accounting guidance) for loss contingencies or the low end of a range of losses if no single probable loss can be estimated. For some loss contingencies, the Company is unable to estimate the amount of the probable loss or range of probable losses. Further, the Company has insurance coverage for certain of these loss contingencies, and as of March 31, 2022, estimates that approximately $2,385 of the amount accrued for these matters are probable of recovery through insurance, which amount is also reported in the Company’s consolidated balance sheet as deferred charges and other assets, net.

During a portion of 2019, the Company initiated a do not consume advisory for some of its water customers in one division served by the Company’s Illinois subsidiary. During the second quarter of 2021, an immaterial amount was accrued for the portion of the fine or penalty that we determined to be probable and estimable of being incurred. In addition, on September 3, 2019, two individuals, on behalf of themselves and those similarly situated, commenced an action against the Company’s Illinois subsidiary in the State court in Will County, Illinois related to this do not consume advisory. The complaint seeks class action certification, attorney's fees, and "damages, including, but not limited to, out of pocket damages, and discomfort, aggravation, and annoyance” based upon the water provided by the Company’s subsidiary to a discrete service area in University Park, Illinois. The complaint contains allegations of damages as a result of supplied water that exceeded the standards established by the federal Lead and Copper Rule. The complaint is in the discovery phase and class certification has not been granted. The Company is vigorously defending against this claim. A claim for the expenses incurred has been submitted to the Company’s insurance carrier for potential recovery of a portion of these costs, and on August 3, 2020, the Company received $2,874 in insurance proceeds. The Company continues to assess the potential loss contingency on this matter. While the final outcome of this claim cannot be predicted with certainty, and unfavorable outcomes could negatively impact the Company, at this time in the opinion of management, the final resolution of this matter is not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Although the results of legal proceedings cannot be predicted with certainty, other than disclosed above, there are no other pending legal proceedings to which the Company or any of its subsidiaries is a party or to which any of its properties is the subject that are material or are expected to have a material effect on the Company’s financial position, results of operations, or cash flows.

In addition to the aforementioned loss contingencies, the Company self-insures its employee medical benefit program, and maintains stop-loss coverage to limit the exposure arising from these claims. The Company’s reserve for these claims totaled $2,470 at March 31, 2022 and represents a reserve for unpaid claim costs, including an estimate for the cost of incurred but not reported claims.

Income Taxes [Abstract]

Income Taxes

Note 14 – Income Taxes

The Company’s effective tax rate was (9.5)% and 2.5% for the three months ended March 31, 2022 and 2021, respectively. The decrease in the effective tax rate for the first quarter is primarily attributed to an increase in our income tax benefit associated with the tax deduction for qualifying infrastructure and the amortization of the customer surcredit tax repair catch-up adjustment during the first quarter of 2022 in our Regulated Natural Gas segment. The statutory Federal tax rate is 21% for the three months ended March 31, 2022 and 2021. For states with a corporate net income tax, the state corporate net income tax rates range from 2.5% to 9.99% for all periods presented. In determining its interim tax provision, the Company reflects its estimated permanent and flow-through tax differences for the taxable year, including the basis difference for the adoption of the tangible property regulations. Qualifying utility asset improvement costs and the amortization of excess deferred income taxes caused the year-to-date effective tax rate to be significantly different from the statutory rate in both 2021 and 2022.

On March 16, 2020, the Company completed the Peoples Gas Acquisition. On March 31, 2020, the Company changed the method of tax accounting for certain qualifying infrastructure investments at its Peoples Natural Gas subsidiary, its largest natural gas subsidiary in Pennsylvania. This change allows a tax deduction for qualifying utility asset improvement costs that were formerly capitalized for tax purposes. Consistent with the Company’s accounting for differences between book and tax expenditures in Pennsylvania, the Company is utilizing the flow-through method to account for this timing difference. In addition, the Company calculated the income tax benefits for qualifying capital expenditures made prior to March 16, 2020 (“catch-up adjustment”) and has recorded a regulatory liability for $160,655 for these income tax benefits. On May 6, 2021, the Pennsylvania Public Utility Commission approved a settlement order which stipulates, among other points, that the catch-up adjustment be provided to utility customers over a five-year period, and the Company can continue to use flow-through accounting for the current tax repair benefit until its next base rate case. The five-year customer surcredit for the catch-up adjustment was initiated in August 2021. During the first quarter of 2022, $12,487 of income tax benefits were amortized as refunds were being made to Peoples Natural Gas customers. In addition, the Company contributed $500 to a customer-bill payment assistance program in July 2021 and in December 2021 provided $5,000 in relief to past-due accounts for natural gas customers impacted by the COVID-19 pandemic through a rate credit fulfilling this requirement.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Recent Accounting Pronouncements

Note 15 – Recent Accounting Pronouncements

Pronouncements to be adopted upon the effective date:

In October 2021, the FASB issued accounting guidance on accounting for acquired revenue contracts with customers in a business combination. The guidance specifies for all acquired revenue contracts, regardless of their timing of payment, the circumstances in which the acquirer should recognize contract assets and contract liabilities that are acquired in a business combination, as well as how to measure those contract assets and contract liabilities. The updated accounting guidance is effective for fiscal years beginning after December 15, 2022 with early adoption permitted. The Company is evaluating the requirements of the updated guidance to determine the impact of adoption.

Pronouncement adopted during the year:

In August 2020, the FASB issued updated accounting guidance on accounting for convertible instruments and contracts in an entity’s own equity. The updated guidance reduces the number of accounting models for convertible debt and convertible preferred stock instruments and makes certain disclosure amendments intended to improve the information provided to users. Additionally, the guidance also amends the derivative guidance for the “own stock” scope exception, which exempts qualifying instruments from being accounted for as derivatives if certain criteria are met. Further, the standard changes the way certain convertible instruments are treated when calculating earnings per share. As permitted, we adopted this updated guidance on January 1, 2022, which did not have a material impact on our consolidated financial statements.
