__________
(a)For ACE, the increase is primarily a result of increased receivable balances.
(b)Recoveries were not material to the Registrants.
(c)For ACE, the increase is primarily a result of increased aging of receivables and a slight decrease in the expected recovery rate.
(d)For PECO, BGE, and DPL, the increase is primarily a result of increased receivable balances due to the increased aging of receivables.
(e)For PHI, Pepco and ACE, the increase is primarily as a result of increased receivable balances.
(f)For PECO, PHI, Pepco, and ACE, the increase in 2022 is primarily related to the termination of the moratoriums in Pennsylvania, the District of Columbia, and New Jersey, which beginning in March 2020, prevented customer disconnections for non-payment. With disconnection activities restarting in January 2022, write-offs of aging accounts receivable increased throughout the year.
(g)For PHI, Pepco, and ACE, the increase is primarily a result of increased aging of receivables and a slight decrease in the expected recovery rate.
