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, WG, and WPS 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 March 31, 2020, $684.6 million, or 58.2%, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses. In addition, in a March 24, 2020 order, the PSCW authorized the deferral of credit losses at WE, WG, and WPS for commercial and industrial customers, to the extent these losses exceed the amount included in rates, as a result of the COVID-19 pandemic and the actions WE, WG, and WPS have been required to take to ensure

essential utility services are available to customers during the public health emergency. Furthermore, pursuant to an April 15, 2020 order addressing certain impacts of the COVID-19 pandemic, the MPSC authorized all Michigan utilities to defer, for potential future recovery, uncollectible expense incurred on or after March 24, 2020 that exceeds the amounts being recovered in rates. The additional protections related to our March 31, 2020 accounts receivable and unbilled revenue balances provided by these orders are still being assessed and are not reflected in the percentages in the above table or related note. See Note 21, Regulatory Environment, for more information.
