(1) | Recorded at cost plus accrued interest, which approximates fair value.
(2) | Amounts may be redeemed on a daily basis with the original issuer.
(3) | Recorded at fair value as determined by quoted market prices (see amounts presented in the table of financial assets and liabilities measured at fair value within this Note).
(4) | Recorded at amortized cost plus accrued interest, which approximates fair value. U.S. Treasury securities included in short-term investments are held-to-maturity investments with maturity dates of less than one year.
​ The Company’s long-term financial instruments are presented in the table of financial assets and liabilities measured at fair value within this Note. ​ Concentrations of Credit Risk of Financial Instruments The Company is potentially subject to concentrations of credit risk related to its cash, cash equivalents, and short-term investments. The Company reduces credit risk by maintaining its cash deposits and short-term investments in accounts and certificates of deposit which are primarily FDIC-insured, or in direct obligations of the U.S. government. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At December 31, 2022 and 2021, cash, cash equivalents, and short-term investments totaling $99.4 million and $42.6 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government. ​ ​ Fair value and carrying value disclosures of financial instruments as of December 31 are presented in the following table: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021 |

New England Pension Fund withdrawal liability(3) | ​ | ​ | 20,100 | ​ | ​ | 18,911 | ​ | ​ | 20,769 | ​ | ​ | 23,521 | ​
​ | ​ | $ | 284,723 | ​ | $ | 276,689 | ​ | $ | 246,299 | ​ | $ | 249,458 | ​
(1) | The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on London Inter-Bank Offered Rate (“LIBOR”), plus a margin, for the year ended December 31, 2021 through October 7, 2022, and effective October 7, 2022, Secured Overnight Financing Rate (“SOFR”), plus a margin, is considered to be priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).
(2) | Fair value of the notes payable was determined using a present value income approach based on quoted interest rates from lending institutions with which the Company would enter into similar transactions (Level 2 of the fair value hierarchy).
(3) | ABF Freight’s multiemployer pension plan obligation with the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”) was restructured under a transition agreement effective on August 1, 2018, which resulted in a related withdrawal liability. The fair value of the outstanding withdrawal liability is equal to the present value of the future withdrawal liability payments, discounted at an interest rate of 5.3% and 3.1% at December 31, 2022 and 2021, respectively, determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy). As of December 31, 2022, the outstanding withdrawal liability totaled $20.1 million, of which $0.7 million and $19.4 million were recorded in accrued expenses and other long-term liabilities, respectively.
​ ​ Assets and Liabilities Measured at Fair Value on a Recurring Basis ​ The following table presents the assets and liabilities that are measured at fair value on a recurring basis: ​

(1) | Included in cash and cash equivalents.
(2) | Nonqualified deferred compensation plan investments consist of U.S. and international equity mutual funds, government and corporate bond mutual funds, and money market funds which are held in a trust with a third-party brokerage firm. Included in other long-term assets, with a corresponding liability reported within other long-term liabilities.
(3) | Included in other long-term assets or other long-term liabilities. The fair values of the interest rate swaps were determined by discounting future cash flows and receipts based on expected interest rates observed in market interest rate curves adjusted for estimated credit valuation considerations reflecting nonperformance risk of the Company and the counterparty, which are generally considered to be in Level 3 of the fair value hierarchy. However, the Company assessed Level 3 inputs as insignificant to the valuation at December 31, 2022 and 2021, and considers the interest rate swap valuations in Level 2 of the fair value hierarchy.
(4) | Included in other long-term liabilities, based on when expected payouts become due. The estimated fair value of contingent consideration for the earnout agreement related to the November 2021 acquisition of MoLo was determined by assessing Level 3 inputs. The Level 3 assessments utilize a Monte Carlo simulation with inputs including scenarios of estimated revenues and earnings before interest, taxes, depreciation and amortization to be achieved for the applicable performance periods, volatility factors applied to the simulations, and the discount rate applied, which was 14.0% and 9.0% as of December 2022 and 2021, respectively. Changes in the significant unobservable inputs might result in a significantly higher or lower fair value at the reporting date.
​ The following table provides the changes in fair value of the liabilities measured at fair value using inputs categorized in Level 3 of the fair value hierarchy: ​
