(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, cash equivalents 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 2018 and 2017 were as follows:

	Percent of Total Revenues
Significant Customer	2018			2017
A		36	%		28	%
B		17	%		14	%
C		12	%		9	%
D		<10	%		<10	%

As of December 29, 2018, the Company had trade accounts receivable due from these four customers that accounted for 61% of total trade accounts receivable as of that date. No other customer balances constitute 10% or more of accounts receivable at December 29, 2018. 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 2018 and 2017:

	Percent of Total Revenues
Country	2018			2017
United States of America		33	%		30	%
Germany		53	%		42	%
Other		14	%		28	%

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 67% and 70% of total revenue in 2018 and 2017, respectively.

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