SUBSEQUENT EVENTS	NOTE 19 SUBSEQUENT EVENTS On January 14, 2022, Artesian Wastewater Management completed its agreement to acquire Tidewater Environmental Services, Inc., or TESI, a wholly-owned subsidiary of Middlesex Water Company, or Middlesex, that provides regulated wastewater services in Delaware. Artesian Wastewater purchased all of the stock of TESI from Middlesex for $6.4 million in cash and other consideration, including forgiveness of a $2.1 million intercompany note due from Middlesex. This acquisition more than doubled the number of wastewater customers served in Sussex County, Delaware. The Delaware Public Service Commission approved this transaction with TESI on October 27, 2021. The Company is still gathering information related to this acquisition and will record the preliminary purchase price allocation in the first quarter of 2022 and finalize the allocation by the end of 2022, once the valuation of assets acquired has been completed.. On February 7, 2022, Artesian Water Company entered into an interest rate lock agreement, or the Agreement, with CoBank, ACB, or CoBank. The Company is seeking to finance a $30 million principal amount First Mortgage Bond, or the Bond. The Agreement allows for a maturity period of 25 years and a fixed interest rate of 4.43% per annum, or the Fixed Rate, for the Bond. The Agreement is effective through May 7, 2022, or the Settlement Date. Pursuant to the Agreement, the Bond is not subject to redemption based on mortgage style amortization. Interest on the outstanding principal balance will be payable quarterly on the 30th day of January, April, July and October each year. The proceeds from the sale of the Bond shall be used to pay down outstanding lines of credit of Artesian Water, with any additional proceeds used to fund future capital investments in Artesian Water. Closing on the debt financing is subject to approval by the DEPSC. Also pursuant to the Agreement, the Company agrees to pay to CoBank, on demand, a broken funding charge if the Company does not, for any reason whatsoever, borrow the entire $30 million principal amount on or before the Settlement Date. The broken funding charge shall be in an amount equal to the present value of the sum of all losses and expenses incurred by CoBank in retiring, liquidating, or reallocating any debt, obligation, or cost incurred or allocated by CoBank to fund or hedge the Fixed Rate. On February 16, 2022, Artesian Water Company signed an agreement, or the Asset Purchase Agreement, to purchase from the Town of Clayton, a Delaware municipality, or Clayton, substantially all of the operating assets of Clayton’s water system, including Clayton’s exclusive franchise territory and the right to provide water service to Clayton’s existing customers, or the Water System. Pursuant to the terms of the Asset Purchase Agreement, Clayton shall transfer to Artesian Water all of Clayton’s right, title and interest in and to substantially all of the municipal water utility, plant and equipment, associated real property, contracts, easements and permits possessed by Clayton at closing related to the Water System. The total purchase price is $5.0 million, less the current payoff amount of any secured debt or debt associated with the Water System. Closing on this transaction is pending due diligence and approval by the Delaware Public Service Commission related to the transfer of exclusive franchise territory. The Asset Purchase Agreement contains customary representations, warranties, covenants and closing conditions for agreements of like type.
