Note 10 - 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 and nine months ended September 30, 2021 and 2020, there were two customers whose purchases represented more than 10% of the Company’s consolidated net sales. Sales to these customers for the three and nine months ended September 30, 2021 and 2020 are as follows:

	Three Months Ended					Three Months Ended
