No amounts were in excess of coverage at December 31, 2018 and 2017. The Company has not incurred any losses on these accounts. The Company extends credit to customers on an unsecured basis in the normal course of business.

The Company analyzes historical bad debts and contract losses, customer concentrations, and customer credit-worthiness when evaluating the adequacy of the allowances.
