Concentration of Credit Risk

12 Months Ended

Sep. 30, 2021

The Company’s cash and cash equivalents and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents are placed with financial institutions that management believes are of high credit quality. Accounts receivable is derived from revenue earned from customers located in the U.S. and internationally and generally do not require collateral. The Company’s trade receivables do not represent a significant concentration of credit risk at September 30, 2021 and 2020 due to the wide variety of customers and markets into which products are sold and their dispersion across geographic areas. The Company does perform ongoing credit evaluations of its customers and maintains an allowance for potential credit losses on trade receivables. As of and for the years ended September 30, 2021, 2020 and 2019, no customer accounted for more than 10% of net sales or net accounts receivable.

The Company operates predominantly in ten countries worldwide and provides a wide range of proven product brands and advanced water and wastewater treatment technologies, mobile and emergency water supply solutions and service contract options through its Integrated Solutions and Services and Applied Product Technologies segments. The Company is a multi-national business, but its sales and operations are primarily in the U.S. External sales to unaffiliated customers are transacted with the Company location that maintains the customer relationship.
