(a) Included in other assets is the cash surrender value of insurance policies on various individuals that are associated with the Company. The carrying amounts of these insurance policies approximates their fair value.

(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 $335 and $1,650 at December 31, 2016 are included in accrued expenses and other current liabilities and other long-term liabilities, respectively.  Interest rate swaps of $286 and $1,215 at December 31, 2015 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, as disclosed on the face of the balance sheet.

(d) Included in accrued expenses and other current liabilities and other long term liabilities in the amounts of $194 and $442, respectively, at December 31, 2016 is the fair value of an obligation for a portion of the potential earn out acquired in conjunction with the acquisition of Henderson. Included in accrued expenses and other current liabilities and other long term liabilities in the amounts of $319 and $442, respectively, at December 31, 2015 is the fair value of an obligation for a portion of the potential earn out acquired in conjunction with the acquisition of Henderson. Fair value is based upon Level 3 discounted cash flow analysis using key inputs of forecasted future sales as well as a growth rate reduced by the market required rate of return.

(e) Included in accrued expenses and other current liabilities in the amount of $1,606 at December 31, 2015 is the fair value of an obligation for the potential earn out incurred in conjunction with the acquisition of substantially all of TrynEx Inc.’s (“TrynEx”) assets. Fair value is based upon Level 3 inputs of a monte carlo simulation analysis using key inputs of forecasted future sales and financial performance as well as a growth rate reduced by the market required rate of return. See reconciliation of liability included below:

(f) Included in Accrued expenses and other current liabilities and Other long term liabilities in the amounts of $5,487 and $4,886, respectively, at December 31, 2016 is the fair value of an obligation for a portion of the potential earn out incurred in conjunction with the acquisition of Dejana.   The carrying amount of the earn out approximates its fair value.  Fair value is based upon Level 3 inputs of a real options approach where gross sales were simulated in a risk-neutral framework using Geometric Brownian Motion, a well-accepted model of stock price behavior that is used in option pricing models such as the Black-Scholes option pricing model, using key inputs of forecasted future sales and financial performance as well as a risk adjusted expected growth rate adjusted appropriately based on its correlation with the market.  See reconciliation of liability included below:
