Significant Customers

Sales to significant customers that represented more than 10 percent of total revenues are as follows:

	Year ended December 31,
	2012		2011
Customer A	17.5	%	19.2	%
Customer B	*		10.9	%
Total	17.5	%	30.1	%

* Sales didn't exceed 10% of the revenue.

The following table summarizes the percentage of total gross accounts receivable from significant customers:

	As of December 31,
	2012		2011
Customer A	20.3	%	25.0	%
Customer B	*		14.4	%
Total	20.3	%	39.4	%

These customers facilitate product sales to a large number of end-users, none of which is known to account for more than 10 percent of the Company’s revenue from product sales. Nevertheless, the loss of one or more of these customers could reduce revenue and have a material adverse effect on the Company’s business and results of operations.
