(1) Our exposure to credit losses for certain regulated utility customers is mitigated by regulatory mechanisms we have in place. Specifically, rates related to all of the customers in our Illinois segment, as well as the residential rates of WE, WPS, and WG in our Wisconsin segment, include riders or other mechanisms for cost recovery or refund of uncollectible expense based on the difference between the actual provision for credit losses and the amounts recovered in rates. As a result, at June 30, 2026, $882.1 million, or 57.7%, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses. See Note 24, Regulatory Environment, for more information on PGL and NSG's UEA rider for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and amounts recovered in rates.

On a consolidated basis, there was a $20.6 million decrease in the allowance for credit losses at June 30, 2025, compared to January 1, 2025. This decrease was largely driven by customer write-offs in Wisconsin in addition to a decrease in past due account balances that we believe was related to a continued focus on collection efforts and the lower energy bills typically seen in the spring and summer months, enabling customers to pay down their arrears. After a customer is disconnected for a period of time without payment on their account, we will write off that customer balance.
