14. Concentration of Credit Risk

Credit Risk

Financial Instruments, which potentially subject the Company to concentration of credit risk, consist principally of cash and cash equivalents, and trade receivables. Concentration of credit risk with respect to trade receivables is generally diversified due to the large number of entities comprising the Company's customer base and their dispersion across geographic areas principally within the United States and international. The Company routinely address the financial strength of its customer and, as a consequence, believes that its receivable credit risk exposure is limited. The Company does not require customers to post collateral.
