We have traditionally experienced high customer concentration, resulting in large accounts receivable from individual customers. The determination for the creditworthiness of these customers and whether or not an allowance is appropriate could have a significant impact on our results of operations for any quarter. As of March 31, 2013 one customer represented approximately 22% of accounts receivable. At December 31, 2012 one customer represented approximately 16% of accounts receivable.
