Capitalization [Abstract]
Capitalization	Note 5 – Capitalization At-the-Market Offering On October 14, 2022, the Company entered into at-the market sales agreements (“ATM”) with third-party sales agents, under which the Company may offer and sell shares of its common stock, from time to time, at its option, having an aggregate gross offering price of up to $500,000 pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-255235). The Company intends to use the net proceeds from the sales of shares through the ATM for working capital, capital expenditures, water and wastewater utility acquisitions and repaying outstanding indebtedness. As of the date of this report, the Company has not sold any shares under the ATM. 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. 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 per unit cash installments of $0.75 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. This 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 represented unsecured senior obligations of the Company. Certain holders of the tangible equity units had early settled their prepaid stock purchase contracts prior to the due date, and, in exchange, the Company issued shares of its common stock. 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 each mandatorily settled for 1.18758 shares of the Company’s common stock, and in the aggregate the Company issued 7,863,354 shares of its common stock. Additionally, the final quarterly installment payment was made, which resulted in the complete pay-off of the amortizing notes. Long-term Debt and Loans Payable In October 2022, Aqua Pennsylvania issued $125,000 of first mortgage bonds due in 2052 with interest rates of 4.50%. The proceeds from these bonds were used to repay existing indebtedness and for general corporate purposes. On May 20, 2022, the Company issued $500,000 of long-term debt (the “Senior Notes”), less expenses of $5,815, due in 2052 with an interest rate of 5.30%. The Company used the net proceeds from the issuance of Senior Notes to (1) to repay $49,700 of borrowings under the Aqua Pennsylvania’s 364-day revolving credit facility and $410,000 of borrowings under the Company’s existing five year unsecured revolving credit facility, and (2) for general corporate purposes. On June 30, 2022, the following debt amendments were executed: (1) Peoples Natural Gas Companies amended its 364-day revolving credit agreement primarily to increase the amount of the facility from $100,000 to $300,000 and to update the termination date of the facility to June 29, 2023, and (2) Aqua Pennsylvania amended its 364-day revolving credit agreement primarily to update the termination date of the facility to June 29, 2023 to coincide with the term of the Peoples Natural Gas Companies’ facility.
