​ At December 31, 2023 and 2022, the fair value of long-term debt, including the current portion, was approximately $1,013,795 and $1,009,020, respectively, which was determined using available market information and methodologies requiring judgment. The carrying value of this debt at such dates was $1,102,771 and $1,121,435, respectively. Since judgment is required in interpreting market information, the fair value of the debt is not necessarily the amount which could be realized in a current market exchange. Senior Unsecured Notes On April 1, 2015 and October 20, 2016, the Company entered into separate Note Purchase Agreements pursuant to which it issued senior unsecured notes (the "Notes") through a private placement. Interest on the Notes is paid semi-annually. The proceeds of the Notes were used for general corporate purposes. The Notes contain certain affirmative and negative covenants. As of December 31, 2023, the Company was in compliance with all of its debt covenants relating to the Notes. The maturity and interest rates of the 2015 Notes and 2016 Notes are as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Amount |  | Maturity Date |  | Interest Rate |
2015 Notes |  | ​ |  |  |  |  |  | ​

​ The Company’s total weighted average effective interest rate and remaining weighted average term, inclusive of the 2015 Notes and 2016 Notes, is 3.3% and 10.4 years, respectively. Term Loan On November 29, 2022, the Company entered into a term loan in the aggregate principal amount of $400,000 (the “Term Loan”), which was borrowed in full. The Term Loan matures on November 29, 2025. The Term Loan bears an interest at a rate based on SOFR, plus a margin ranging from 0.75% to 1.75% based on the Company’s consolidated net leverage ratio. The proceeds of the Term Loan were used to pay a portion of the purchase price in connection with the acquisition of Fori. The agreement governing the Term Loan (the “Term Loan Credit Agreement”) contains representations and warranties, as well as customary affirmative, negative and financial covenants for credit facilities of this type, including limitations on the Company and its subsidiaries with respect to liens, investments, distributions, mergers and acquisitions, dispositions of assets and transactions with affiliates. The Term Loan Credit Agreement requires the Company to maintain a minimum consolidated fixed charges coverage ratio and maximum consolidated net leverage ratio. As of December 31, 2023, the Company was in compliance with all of its covenants. Revolving Credit Agreement On April 23, 2021, the Company amended and restated the agreement governing its line of credit by entering into the Second Amended and Restated Credit Agreement (“Credit Agreement”). The Credit Agreement has a line of credit totaling $500,000, has a term of 5 years with a maturity date of April 23, 2026 and may be increased, subject to certain conditions including the consent of its lenders, by an additional amount up to $150,000. On March 8, 2023, the Credit Agreement was amended to replace the LIBOR rate to a term secured overnight finance rate (“SOFR”); as such, the interest rate on borrowings is based on SOFR plus a spread of 0.85% to 1.85% based on (1) the Company’s net leverage ratio and (2) a credit spread adjustment. The Credit Agreement contains customary representations and warranties, as well as customary affirmative, negative and financial covenants for credit facilities of this type (subject to negotiated baskets and exceptions), including limitations on the Company and its subsidiaries with respect to liens, investments, distributions, mergers and acquisitions, dispositions of assets and transactions with affiliates. As of December 31, 2023, the Company was in compliance with all of its covenants and had no outstanding borrowings under the Credit Agreement. The Company has other lines of credit and debt agreements totaling $89,145. As of December 31, 2023 the Company was in compliance with all of its covenants and had $2,435 outstanding at December 31, 2023. Other Maturities of long-term debt, including payments for amounts due banks, for the five years succeeding December 31, 2023 are $2,439 in 2024, $500,005 in 2025, $0 in 2026, $0 in 2027, $100,000 in 2028 and $500,000 thereafter. Total interest paid was $29,340 in 2023, $23,547 in 2022 and $23,752 in 2021. The difference between interest paid and interest expense is due to the accrual of interest associated with the Senior Unsecured Notes and interest rate derivative contracts discussed in Note 14.
