Concentration of Credit Risk

(14) Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, trade receivables and note receivable. The Company maintains its cash and cash equivalents in financial institutions and brokerage accounts. To the extent that such deposits exceed the maximum insurance levels, they are uninsured. In regard to trade receivables, the Company performs ongoing evaluations of its customers' financial condition as well as general economic conditions and, generally, requires no collateral from its customers.
