Concentration Risk Credit Risk
ConcentrationRiskCreditRisk
|
The geographic concentration of our customers did not contribute significantly to our overall exposure to credit risk. We periodically review customers' credit ratings, financial statements, and historical payment performance and require them to provide collateral or other security as needed. Credit risk exposure at WE, WPS, WG, PGL, and NSG is mitigated by their recovery mechanisms for uncollectible expense discussed in Note 1(d), Operating Revenues. As a result, we did not have any significant concentrations of credit risk at December 31, 2021. In addition, there were no customers that accounted for more than 10% of our revenues for the year ended December 31, 2021 | |
