The following table presents the components of cash and cash equivalents and short-term investments:

(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 primarily in FDIC-insured accounts and placing its short-term investments primarily in FDIC-insured certificates of deposit. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At March 31, 2021 and December 31, 2020, cash, cash equivalents, and short-term investments totaling $152.9 million and $156.4 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government.

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 (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:

(1)	The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on LIBOR, plus a margin, that 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 (see in Note I to the consolidated financial statements in Item 8 of the Company’s 2020 Annual Report on Form 10-K). 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 3.4% and 2.6% at March 31, 2021 and December 31, 2020, respectively, determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy). Included in other long-term liabilities with the current portion included in accrued expenses.

(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 considered to be in Level 3 of the fair value hierarchy. The Company assessed Level 3 inputs as insignificant to the valuation at March 31, 2021 and December 31, 2020 and considers the interest rate swap valuations in Level 2 of the fair value hierarchy.
