Payments due in 2024 include payback of the committed line of credit. The committed line of credit is reviewed annually, and upon favorable outcome, would likely be extended for another year. Payments due in 2024 also include potential payments of $12,000 on the variable rate bonds (due 2029) which would only be payable if all bonds were tendered and could not be remarketed, or in the event the Company was unable to, or chose not to, renew the letter of credit backing the bonds. There is currently no such indication of this happening. Fixed Rate Long-Term Debt The 8.43% Senior Notes, Series D had a maturity date of December 18, 2022. The Company retired the $7,500 notes using funds available under its line of credit. Variable Rate Long-Term Debt On May 7, 2008, the PEDFA issued $12,000 aggregate principal amount of PEDFA Exempt Facilities Revenue Refunding Bonds, Series A of 2008 (the “Series A Bonds”) for the Company’s benefit pursuant to the terms of a trust indenture, dated as of May 1, 2008, between the PEDFA and Manufacturers and Traders Trust Company, as trustee. The PEDFA then loaned the proceeds of the offering of the Series A Bonds to the Company pursuant to a loan agreement, dated as of May 1, 2008, between the Company and the PEDFA. The loan agreement provides for a $12,000 loan with a maturity date of October 1, 2029. Amounts outstanding under the loan agreement are the Company’s direct general obligations. The proceeds of the loan were used to redeem the PEDFA Exempt Facilities Revenue Bonds, Series B of 2004 (the “2004 Series B Bonds”). The 2004 Series B Bonds were redeemed because the bonds were tendered and could not be remarketed due to the downgrade of the bond insurer’s credit rating. Borrowings under the loan agreement bear interest at a variable rate as determined by PNC Capital Markets, as remarketing agent, on a periodic basis elected by the Company, which has currently elected that the interest rate be determined on a weekly basis. The remarketing agent determines the interest rate based on the current market conditions in order to determine the lowest interest rate which would cause the Series A Bonds to have a market value equal to the principal amount thereof plus accrued interest thereon. The variable interest rate under the loan agreement averaged 1.25% in 2022 and 0.07% in 2021. As of December 31, 2022 and 2021, the interest rate was 3.75% and 0.13%, respectively. The holders of the $12,000 Series A Bonds may tender their bonds at any time. When the bonds are tendered, they are subject to an annual remarketing agreement, pursuant to which a remarketing agent attempts to remarket the tendered bonds according to the terms of the indenture. In order to keep variable interest rates down and to enhance the marketability of the Series A Bonds, the Company entered into a Reimbursement, Credit and Security Agreement with PNC Bank, National Association (“the Bank”) dated as of May 1, 2008. This agreement provides for a direct pay letter of credit issued by the Bank to the trustee for the Series A Bonds. The Bank is responsible for providing the trustee with funds for the timely payment of the principal and interest on the Series A Bonds and for the purchase price of the Series A Bonds that have been tendered or deemed tendered for purchase and have not been remarketed. The Company’s responsibility is to reimburse the Bank the same day as regular interest payments are made, and within fourteen months for the purchase price of tendered bonds that have not been remarketed. The reimbursement period for the principal is immediate at maturity, upon default by the Company, or if the Bank does not renew the Letter of Credit. The current expiration date of the Letter of Credit is June 30, 2024. It is reviewed annually for a potential extension of the expiration date. The Company may elect to have the Series A Bonds redeemed, in whole or in part, on any date that interest is payable for a redemption price equal to the principal amount thereof plus accrued interest to the date of redemption. The Series A Bonds are also subject to mandatory redemption for the same redemption price in the event that the IRS determines that the interest payable on the Series A Bonds is includable in gross income of the holders of the bonds for federal tax purposes. Interest Rate Swap Agreement In connection with the issuance of the PEDFA 2004 Series B Bonds, the Company entered into an interest rate swap agreement with a counterparty, in the notional principal amount of $12,000. The Company elected to retain the swap agreement for the 2008 Series A Bonds. Interest rate swap agreements derive their value from underlying interest rates. These transactions involve both credit and market risk. The notional amounts are amounts on which calculations, payments, and the value of the derivative are based. Notional amounts do not represent direct credit exposure. Direct credit exposure is limited to the net difference between the calculated amounts to be received and paid, if any. Such difference, which represents the fair value of the swap, is reflected on the Company’s balance sheets. See Note 7 for additional information regarding the fair value of the swap. The interest rate swap will terminate on the maturity date of the 2008 Series A Bonds (which is the same date as the maturity date of the loan under the loan agreement), unless sooner terminated pursuant to its terms. In the event the interest rate swap terminates prior to the maturity date of the 2008 Series A Bonds, either the Company or the swap counterparty may be required to make a termination payment to the other based on market conditions at such time. The Company is exposed to credit-related losses in the event of nonperformance by the counterparty. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures, and does not expect the counterparty to default on its obligations. Notwithstanding the terms of the swap agreement, the Company is ultimately obligated for all amounts due and payable under the loan agreement. The interest rate swap agreement contains provisions that require the Company to maintain a credit rating of at least BBB- with Standard & Poor’s. On August 9, 2022, Standard & Poor’s affirmed the Company’s credit rating at A-, with a stable outlook and adequate liquidity. If the Company’s rating were to fall below this rating, it would be in violation of these provisions, and the counterparty to the derivative could request immediate payment if the derivative was in a liability position. The Company’s interest rate swap was in a liability position as of December 31, 2022. If a violation was triggered on December 31, 2022, the Company would have been required to pay the counterparty approximately $719. The Company’s interest rate swap agreement provides that it pays the counterparty a fixed interest rate of 3.16% on the notional amount of $12,000. In exchange, the counterparty pays the Company a floating interest rate (based on 59% of the U.S. Dollar one-month LIBOR rate) on the notional amount. In the fourth quarter of 2022, the Company amended the interest rate swap agreement and changed the floating interest rate to 59% of the daily simple Secured Overnight Financing Rate, or SOFR, plus a spread adjustment of 11.448 basis points commencing upon the discontinuance of LIBOR in 2023. No other terms or conditions of the interest rate swap agreement were modified. The floating interest rate paid to the Company is intended, over the term of the swap, to approximate the variable interest rate on the loan agreement and the interest rate paid to bondholders, thereby managing its exposure to fluctuations in prevailing interest rates. The Company’s net payment rate on the swap averaged 2.04% in 2022 and 3.10% in 2021. As of December 31, 2022, there was a spread of 122 basis points between the variable rate paid to bondholders and the variable rate received from the swap counterparty, which equated to an overall effective rate of 4.38% (including variable interest and swap payments). As of December 31, 2021, there was a spread of 7 basis points which equated to an overall effective rate of 3.23% (including variable interest and swap payments). Line of Credit Borrowings As of December 31, 2022, the Company maintained a $50,000 unsecured, committed line of credit at an interest rate of LIBOR plus 1.05% with an unused commitment fee and an interest rate floor. In the third quarter of 2022, the Company renewed its committed line of credit and extended the maturity date to September 2024. As part of the renewal, the interest rate changed from LIBOR plus 1.05% to a successor rate of SOFR plus 1.17% on January 1, 2023, in advance of the likely discontinuation of LIBOR in 2023. No other terms or conditions of the line of credit agreement were modified. Average borrowings outstanding under the lines of credit were $13,428 in 2022 and $11,487 in 2021. The average cost of borrowings under the lines of credit was 2.11% during 2022 and 1.30% during 2021. The weighted average interest rate on the line of credit borrowings was 5.17% as of December 31, 2022 and 1.30% as of December 31, 2021. The Company utilizes a cash management account that is directly connected to its line of credit. Excess cash generated automatically pays down outstanding borrowings under the line of credit. If there are no outstanding borrowings, the cash is used as an earnings credit to reduce banking fees. Likewise, if additional funds are needed beyond what is generated internally, funds are automatically borrowed under the line of credit. The Company borrowed $29,740 and $29,320 under its line of credit and incurred a cash overdraft of $3,175 and $1,746, which was recorded in accounts payable, as of December 31, 2022 and 2021, respectively. Debt Covenants and Restrictions The terms of the debt agreements carry certain covenants and limit in some cases the Company’s ability to borrow additional funds, to prepay its borrowings and include certain restrictions with respect to declaration and payment of cash dividends and the Company’s acquisition of its stock. Under the terms of the most restrictive agreements, the Company cannot borrow in excess of 60% of its utility plant, and cumulative payments for dividends and acquisition of stock since December 31, 1982 may not exceed $1,500 plus net income since that date. As of December 31, 2022, none of the earnings retained in the business are restricted under these provisions. The Company’s debt is unsecured. The Company’s line of credit requires it to maintain a minimum equity to total capitalization ratio (defined as the sum of equity plus funded debt) and a minimum interest coverage ratio (defined as net income plus interest expense plus income tax expense divided by interest expense). As of December 31, 2022, the Company was in compliance with these covenants.
