Accounts Receivable
ACCOUNTS RECEIVABLE
Credit is extended based upon an evaluation of the customer’s financial condition and, while collateral is not required, the Company periodically receives surety bonds that guarantee payment. Credit terms are consistent with industry standards and practices. The amounts of trade accounts receivable at September 30, 2017 and December 31, 2016 have been reduced by an allowance for doubtful accounts of $2,138 and $1,417, respectively.
