Schedule of Commercial Paper Borrowings

The following table reflects the Registrants' commercial paper programs supported by the revolving credit agreements and bilateral credit agreements at December 31, 2023 and 2022:

	Credit Facility Size at December 31,					Outstanding Commercial Paper at December 31,				Average Interest Rate on Commercial Paper Borrowings at December 31,
Commercial Paper Issuer	2023(a)			2022(a)		2023		2022		2023		2022
Exelon(b)	$	4,000		$	4,000	$	1,624	$	1,938	5.58	%	4.77	%
ComEd	$	1,000		$	1,000	$	202	$	427	5.53	%	4.71	%
PECO	$	600		$	600	$	165	$	239	5.57	%	4.71	%
BGE	$	600		$	600	$	336	$	409	5.59	%	4.81	%
PHI(c)	$	900		$	900	$	394	$	414	5.60	%	4.78	%
Pepco	$	300	(d)	$	300	$	132	$	299	5.59	%	4.79	%

ACE	$	300	(d)	$	300	$	199	$	—	5.60	%	—	%

__________

(a)Excludes credit facility agreements arranged at minority and community banks. See below for additional information.

(b)Includes revolving credit agreements at Exelon Corporate with a maximum program size of $900 million as of December 31, 2023 and December 31, 2022. Exelon Corporate had $527 million in outstanding commercial paper as of December 31, 2023 and $449 million outstanding commercial paper as of December 31, 2022.

(c)Represents the consolidated amounts of Pepco, DPL, and ACE.

(d)The standard maximum program size for revolving credit facilities is $300 million each for Pepco, DPL and ACE based on the credit agreements in place. However, the facilities at Pepco, DPL, and ACE have the ability to flex to $500 million, $500 million, and $350 million, respectively. The borrowing capacity may be increased or decreased during the term of the facility, except that (i) the sum of the borrowing capacity must equal the total amount of the facility, and (ii) the aggregate amount of credit used at any given time by each of Pepco, DPL, or ACE may not exceed $900 million or the maximum amount of short-term debt the company is permitted to have outstanding by its regulatory authorities. The total number of the borrowing reallocations may not exceed eight per year during the term of the facility. In January 2024, this ability was utilized to increase ACE's program size to $350 million. As a result, the program size for Pepco did not change and DPL was decreased to $250 million, which prevents the aggregate amount of outstanding short-term debt from exceeding the $900 million limit.

Schedule of Aggregate Bank Commitments, Credit Facility Borrowings, and Available Capacity

The adders for the prime based borrowings and SOFR-based borrowings are presented in the following table:

	Exelon(a)	ComEd	PECO	BGE	Pepco	DPL	ACE
