Note L - Financial Instruments and Fair Value Measurements
 
Financial Risk Management Objectives and Policies

The Company is exposed primarily to credit, interest rate and currency exchange rate risks which arise in the ordinary course of business.
 
Credit Risk
 
Credit risk is the potential financial loss resulting from the failure of a customer or counterparty to settle its financial and contractual obligations to the Company, as and when they become due. The primary credit risk for the Company is its accounts receivable due from customers. The Company has established credit limits for customers and monitors their balances to mitigate the risk of loss. As September 30, 2017 and December 31, 2016, there were no significant concentrations of credit risk. No single customer represented more than 10% of the Company's net accounts receivable as of September 30, 2017 or at December 31, 2016. The maximum exposure to credit risk is primarily represented by the carrying amount of the Company's accounts receivable.

Interest Rate Risk

The Company's exposure to the risk of changes in market interest rates relates primarily to the Company's debt, which bears interest at variable rates based on the LIBOR rate plus a margin spread of 1.75% to 2.50%. The Company has an interest rate swap with a notional amount of $15,306,250 on September 30, 2017 to convert a portion of its 2017 Term Loan from variable to fixed rates. The valuation of this swap is determined using the three month LIBOR rate index and mitigates the Company's exposure to interest rate risk.

Fair Value Measurements

Assets and liabilities that require fair value measurement are recorded at fair value using market and income valuation approaches and considering the Company's and counterparty's credit risk. The Company uses the market approach and the income approach to value assets and liabilities as appropriate. The assets or liabilities requiring fair value measurements on September 30, 2017 are as follows:

  
Fair Value
 
Level 1
 
Level 2
 
Level 3
Financial Liabilities
      Interest rate swap
 
 
$      82,302
 
 
$              --
 
 
$   82,302
 
 
$          --
Total liabilities
 
$      82,302
 
$              --
 
 $  82,302
 
$          --

The Company's interest rate swap is not an exchange-traded instrument. However, it is valued based on observable inputs for similar liabilities and accordingly is classified as Level 2. The amount of the interest rate swap is included in other accrued liabilities.
