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 December 31, 2021 and 2020, cash, cash equivalents, and short-term investments totaling $42.6 million and $156.4 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:

(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. 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 3.1% and 2.6% at December 31, 2021 and 2020, respectively, determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy). As of December 31, 2021, the outstanding withdrawal liability totaled $20.8 million, of which $0.7 million and $20.1 million was recorded in accrued expenses and other long-term liabilities, respectively.

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, 2021 and 2020 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 an earn-out 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 9.0% as of December 2021. A 100 basis point decrease in the discount rate would increase the liability by $4.2 million. Subsequent changes to fair value as a result of recurring assessments will be recognized in operating income.

Assets Measured at Fair Value on a Nonrecurring Basis

There were no assets remeasured on a nonrecurring basis at December 31, 2021 or 2020.
