Concentration of Risk
Financial instruments which potentially subject the Company to credit risk consist primarily of cash, cash equivalents and trade receivables.
The Company maintains cash and cash equivalents with various major financial institutions. Cash equivalents include investments in commercial paper of companies with high credit ratings, investments in money market securities and securities backed by the U.S. Government. At times such amounts may exceed the F.D.I.C. limits. The Company limits the amount of credit exposure with any one financial institution and believes that no significant concentration of credit risk exists with respect to cash investments.
Trade receivables subject the Company to the potential for credit risk with customers. To reduce credit risk, the Company performs ongoing evaluations of its customers' financial condition.
