- 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, 2019

and

2018,

there were

two

customers 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, 2019

and

2018

are as follows:

	Three Months Ended					Three Months Ended
