_________

(a)For ComEd, the change in current period provision for expected credit losses is primarily a result of increased receivable balances.

(b)For BGE, DPL and ACE, the change in current period provision for expected credit losses is primarily a result of decreased receivable balances.

(c)For Pepco the change in current period provision for expected credit losses is primarily a result of receivables increasing at a slower pace versus the prior period.

(d)For PECO and BGE the change in write-offs is primarily a result of increased disconnection activities.

(e)For PHI, ACE, and Pepco, write-offs are primarily attributable to the termination of the moratorium in the service territory for each operating company, which beginning in 2020, prevented customer disconnections for non-payment. Disconnection activities across the service territories resumed from September 2020 through January 2022, resulting in write-offs of aged accounts receivable.

(f)For DPL, the change in write-offs is primarily attributable to unfavorable customer payment behavior.

(g)Recoveries were not material to the Registrants.
