(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 2015, 2014 and 2013 were as follows:

	Percent of Total Revenues
Significant Customer	2015			2014			2013
A		27	%		38	%		42	%
B		23	%		21	%		23	%
C		10	%		10	%		8	%

As of December 26, 2015, the Company had trade accounts receivable due from these three customers that accounted for 63% 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.

The Company’s revenue was derived from the following countries in 2015, 2014, and 2013:

	Percent of Total Revenues
Country	2015			2014			2013
United States of America		21	%		20	%		16	%
Germany		50	%		59	%		65	%
Other		29	%		21	%		19	%

Many of the Company’s customers based in the United States conduct design, purchasing and payable functions in the United States, but manufacture overseas. Revenue generated from shipments made to customers’ locations outside the United States accounted for 80%, 80% and 84% of total revenue in 2015, 2014 and 2013, respectively.

All of the Company’s long-lived assets and operations are located in the United States.
