  SIGNIFICANT CUSTOMERS

The Company sells its products primarily through 

third

-party distributors and value-added resellers, and directly to original equipment manufacturers, original design manufacturers and electronic manufacturing service providers. The following table summarizes those customers with sales equal to or greater than 

10%

 of the Company's total revenue, or with accounts receivable balances greater than 

10%

 of the Company’s total accounts receivable:

	Revenue									Accounts Receivable
	Year Ended December 31,									December 31,
Customer	2018			2017			2016			2018			2017

B (distributor)		10	%		*			*			16	%		*
C (distributor)		*			10	%		*			*			*
D (value-added reseller)		*			*			*			*			15	%

* Represents less than

10%.

The Company’s agreements with these 

third

-party distributors and value-added reseller were made in the ordinary course of business and 

may 

be terminated with or without cause by these customers with advance notice. Although the Company 

may 

experience a short-term disruption in the distribution of its products and a short-term decline in revenue if its agreement with any of these customers was terminated, the Company believes that such termination would 

not

 have a material adverse effect on its financial statements because it would be able to engage alternative distributors, resellers and other distribution channels to deliver its products to end customers within a short period following the termination of the agreement with the customer.
