FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS |
FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS | NOTE B – FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS ​ Financial Instruments ​ The following table presents the components of cash and cash equivalents and short-term investments: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | March 31 | ​ | December 31 |
​ | ​ | 2025 | ​ | 2024 |
​ | ​ | (in thousands) | ​
Cash and cash equivalents | ​ | ​ | ​ | ​ | ​ | ​ | ​
Cash deposits(1) | ​ | $ | 55,945 | ​ | $ | 83,048 | ​
Money market funds(2) | ​ |  | 18,177 | ​ |  | 44,396 | ​
Total cash and cash equivalents | ​ | $ | 74,122 | ​ | $ | 127,444 | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Short-term investments | ​ | ​ | ​ | ​ | ​ | ​ | ​
Certificates of deposit(3) | ​ | $ | 24,552 | ​ | $ | 29,759 | ​
​
(1) | Recorded at cost plus accrued interest, which approximates fair value.
(2) | 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).
(3) | Recorded at cost plus accrued interest, which approximates fair value due to its short-term nature and is categorized in Level 2 of the fair value hierarchy.
​ 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 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 March 31, 2025 and December 31, 2024, cash deposits and short-term investments totaling $38.0 million and $51.7 million, respectively, were not FDIC‑insured. The Company also holds money market funds, which are invested in U.S. government securities and repurchase agreements collateralized solely by U.S. government securities. ​ Fair Value Disclosure of Financial Instruments Fair value disclosures are made in accordance with the following hierarchy of valuation techniques based on whether the inputs of market data and market assumptions used to measure fair value are observable or unobservable: ​
| ● | Level 1 — Quoted prices for identical assets and liabilities in active markets.
| ● | Level 2 — Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
| ● | Level 3 — Unobservable inputs (based on the Company’s market assumptions) that are significant to the valuation model.
​ Fair value and carrying value disclosures of financial instruments are presented in the following table: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | March 31 | ​ | December 31 | ​
​ |  | 2025 |  | 2024 |
​ | ​ | (in thousands) | ​
​ | ​ | ​ | Carrying |  | ​ | Fair |  | ​ | Carrying |  | ​ | Fair | ​

Credit Facility(1) | ​ | $ | 25,000 | ​ | $ | 25,000 | ​ | $ | — | ​ | $ | — | ​
Notes payable(2) | ​ |  | 189,220 | ​ |  | 189,070 | ​ |  | 189,134 | ​ |  | 187,675 | ​
New England Pension Fund withdrawal liability(3) | ​ | ​ | 18,483 | ​ | ​ | 16,916 | ​ | ​ | 18,671 | ​ | ​ | 16,783 | ​
​ | ​ | $ | 232,703 | ​ | $ | 230,986 | ​ | $ | 207,805 | ​ | $ | 204,458 | ​
​
(1) | The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on Secured Overnight Financing Rate (“SOFR”), plus a margin, 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 5.8% and 6.0% at March 31, 2025 and December 31, 2024, respectively, determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy). As of March 31, 2025, the outstanding withdrawal liability totaled $18.5 million, of which $0.8 million was recorded in accrued expenses, and the remaining portion was recorded in other long-term liabilities.
​ 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) | The estimated fair value of contingent consideration related to the acquisition of MoLo is determined by assessing Level 3 inputs. The Level 3 assessments utilize a Monte Carlo simulation with inputs including scenarios of estimated revenues and expenses to be achieved for the applicable performance period, volatility factors applied to the simulation, and the discount rate applied, which was 12.9% as of December 31, 2024. Fair value of the contingent consideration was qualitatively assessed as of March 31, 2025, which involved analyzing the likelihood of achieving adjusted EBITDA thresholds, as defined by the Agreement and Plan of Merger for our acquisition of MoLo. Changes in the significant unobservable inputs might result in a significantly higher or lower fair value at the reporting date.
​ ​ ​ Assets Measured at Fair Value on a Nonrecurring Basis ​ The Company remeasures certain assets on a nonrecurring basis upon events or changes in circumstances that indicate the carrying amount may not be recoverable. During the first quarter of 2024, the Company was notified that Phantom Auto was ceasing operations due to liquidity concerns from failing to secure additional funding from investors or lenders. As a result, the Company assessed the likelihood of recovering its investment as remote and recorded a pre-tax, noncash impairment charge of $28.7 million, to write off the equity investment in Phantom Auto, which was recognized below the operating income line in “Other, net” within “Other income (costs).”
