(a)  Included in Non-qualified benefit plan assets is the cash surrender value of insurance policies on various individuals that are associated with the Company. The carrying amount of these insurance policies approximates their fair value and is considered Level 2 inputs.

​

(b) Valuation models are calibrated to initial trade price. Subsequent valuations are based on observable inputs to the valuation model (e.g. interest rates and credit spreads). Model inputs are changed only when corroborated by market data. A credit risk adjustment is made on each swap using observable market credit spreads. Thus, inputs used to determine fair value of the interest rate swap are Level 2 inputs.  Interest rate swaps of $4,074 and $6,797 at March 31, 2021 are included in Accrued expenses and other current liabilities and Other long-term liabilities, respectively.  Interest rate swaps of $4,075 and $8,998 at December 31, 2020 are included in Accrued expenses and other current liabilities and Other long-term liabilities, respectively.

​

(c)  The fair value of the Company’s long-term debt, including current maturities, is estimated using discounted cash flows based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements, which is a Level 2 input for all periods presented. Meanwhile, long-term debt is recorded at carrying amount, net of discount and deferred debt issuance costs, as disclosed on the face of the balance sheet.
