Concentrations of Credit Risk

(10) Concentrations of Credit Risk, Significant Customers and Geographic Information

Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and trade accounts receivable. The Company maintains such cash deposits in a high credit quality financial institution.

The Company extends credit to customers who consist principally of microelectronics systems companies in the United States, Europe and Asia. The Company generally does not require collateral or other security as a condition of sale rather relying on credit approval, balance limitation and monitoring procedures to control credit risk of trade accounts receivable. Management conducts on-going credit evaluations of its customers, and historically the Company has not experienced any significant credit-related losses with respect to its trade accounts receivable.

Revenues from significant customers as a percentage of total revenues in 2011, 2010 and 2009 were as follows:

	Percent of Total Revenues
Significant Customer	2011	2010	2009
A	42%	34%	25%
B	15%	27%	24%
C	14%	7%	13%

As of December 31, 2011, the Company had trade accounts receivable due from these three customers that accounted for 67% of total trade accounts receivable as of that date. Management believes that any credit risks have been properly provided for in the accompanying financial statements.
