NOTE

2.

CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and accounts receivable. With regard to cash, we maintain our excess cash balances in checking accounts at primarily

two

financial institutions,

one

in the United States and

one

in China. The account in the United States

may

at times exceed federally insured limits. Of the

$399

in cash at

June 30, 2019,

approximately

$333

was held at banks located in China. We grant credit to customers in the normal course of business and do

not

require collateral on our accounts receivable.

Our largest customer has

two

divisions that together accounted for

10%

or more of our net sales during the

three

and

six

months ended

June 30, 2019

and

2018.

One division accounted for approximately

21%

and

22%

of net sales for the

three

and

six

months ended

June 30, 2019,

respectively, and approximately

21%

and

20%

for both the

three

and

six

months ended

June 30, 2018.

The other division accounted for approximately

2%

of net sales for both the

three

months and

six

ended

June 30, 2019,

and approximately

1%

net sales for both the

three

and

six

months ended

June 30, 2018.

Together they accounted for approximately

23%

and

24%

of net sales for the

three

and

six

months ended

June 30, 2019,

respectively, and approximately

22%

and

21%

of net sales for the

three

and

six

months ended

June 30, 2018,

respectively. Accounts receivable from the customer at

June 30, 2019

and

December 31, 2018

represented approximately

22%

and

16%

of our total accounts receivable, respectively.

Export sales represented approximately

17%

and

21%

of net sales for the

three

months ended

June 30, 2019

and

2018,

respectively. Export sales represented

18%

and

20%

of net sales for the

six

months ended

June 30, 2019
