(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 $385 and $3,874 at June 30, 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 and deferred debt issuance costs, as disclosed on the face of the balance sheet.

(d)  Included in accrued expenses and other current liabilities in the amount of $0 and  $2,032 at June 30, 2016 and June 30, 2015, respectively, is an obligation for a portion of the potential earn out incurred in conjunction with the acquisition of substantially all of the assets of TrynEx, Inc. (“TrynEx”).  The carrying amount of the earn out approximates its fair value.  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:

(e) Included in accrued expenses and other current liabilities and other long term liabilities in the amounts of $263 and $442, respectively, at June 30, 2016 is the fair value of an obligation for a portion of the potential earn out acquired in conjunction with the acquisition of Henderson Enterprise Group, Inc. (“Henderson”).   Included in accrued expenses and other current liabilities and other long term liabilities in the amounts of $272 and $442, respectively, at June 30, 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. See reconciliation of liability included below:
