(1) These expected credit losses are deferred as regulatory costs on the balance sheets, as these amounts are ultimately recovered in rates. Amounts include uncollectible costs for hardship accounts and other customer receivables, including uncollectible amounts related to uncollectible energy supply costs. The increases in the allowance for uncollectible hardship accounts at Eversource and CL&P in 2023 primarily relate to increased customer enrollment in disconnection prevention programs in Connecticut.
