Note 7 - Concentration of Credit Risk

Concentration of credit risk with respect to trade accounts receivable is generally limited due to the large number of entities comprising the Company's customer base. The Company performs ongoing credit evaluations and provides an allowance for potential credit losses against the portion of accounts receivable which is estimated to be uncollectible. Such losses have historically been within management's expectations. During the three months ended March 31, 2014, there were two customers whose purchases represented more than 10% of the Company’s consolidated net sales. During the three ended March 31, 2013, there was one customer whose purchases represented more than 10% of the Company’s consolidated net sales, respectively. Sales to these customers for the three months ended March 31, 2014 and 2013 are as follows:
