CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING INFORMATION

This Report contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks
and  uncertainties  including,  among  others,  those  related  to  the  timing,  manner,  tax-free  nature  and  expected  benefits  associated  with  the  potential
separation  of Exelon’s competitive power generation  and  customer-facing  energy  business  from  its  six  regulated  electric  and  gas  utilities.  Words  such  as
“could,”  “may,”  “expects,”  “anticipates,”  “will,”  “targets,”  “goals,”  “projects,”  “intends,”  “plans,”  “believes,”  “seeks,”  “estimates,”  “predicts,”  and  variations  on
such words, and similar expressions that reflect our current views with respect to future events and operational, economic and financial performance, are
intended to identify such forward-looking statements.

The factors that could cause actual results to differ materially from the forward-looking statements made by the Registrants include those factors discussed
herein, including those factors discussed with respect to the Registrants discussed in (a) Part I, ITEM 1A. Risk Factors, (b) Part II, ITEM 7. Management’s
Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations,  (c)  Part  II,  ITEM  8.  Financial  Statements  and  Supplementary  Data:  Note  19,
Commitments  and  Contingencies,  and  (d)  other  factors  discussed  in  filings  with  the  SEC  by  the  Registrants.  Readers  are  cautioned  not  to  place  undue
reliance on these forward-looking statements, which apply only as of the date of this Report. None of the Registrants undertakes any obligation to publicly
release any revision to its forward-looking statements to reflect events or circumstances after the date of this Report.

On  February  21,  2021,  Exelon’s  Board  of  Directors  approved  a  plan  to  separate  the  Utility  Registrants  and  Generation,  creating  two  publicly  traded
companies with the resources necessary to best serve customers and sustain long-term investment and operating excellence. The separation gives each
company  the  financial  and  strategic  independence  to  focus  on  its  specific  customer  needs,  while  executing  its  core  business  strategy.  See  Note  26  —
Subsequent Events of the Combined Notes to Consolidated Financial Statements for additional information.

Business Services

Through its business services subsidiary, BSC, Exelon provides its subsidiaries with a variety of support services at cost, including legal, human resources,
financial,  information  technology,  and  supply  management  services.  PHI  also  has  a  business  services  subsidiary,  PHISCO,  which  provides  a  variety  of
support services at cost, including legal, accounting, engineering, customer operations, distribution and transmission planning, asset management, system
operations,  and  power  procurement,  to  PHI  operating  companies.  The  costs  of  BSC  and  PHISCO  are  directly  charged  or  allocated  to  the  applicable
subsidiaries. The results of Exelon’s corporate operations are presented as “Other” within the consolidated financial statements and include intercompany
eliminations unless otherwise disclosed.

Generation

Generation, one of the largest competitive electric generation companies in the United States as measured by owned and contracted MW, physically delivers
and markets power across multiple geographic regions through its customer-facing business, Constellation. Constellation sells electricity and natural gas,
including renewable energy, in competitive energy markets to both wholesale and retail customers. Generation leverages its energy generation portfolio to
ensure delivery of energy to both wholesale and retail customers under long-term and short-term contracts, and in wholesale power markets. Generation
operates  in  well-developed  energy  markets  and  employs  an  integrated  hedging  strategy  to  manage  commodity  price  volatility.  Generation's  fleet  also
provides geographic and supply source diversity. Generation’s customers include distribution utilities, municipalities, cooperatives, financial institutions, and
commercial,  industrial,  governmental,  and  residential  customers  in  competitive  markets.  Generation’s  customer-facing  activities  foster  development  and
delivery of other innovative energy-related products and services for its customers.

Generation is a public utility under the Federal Power Act and is subject to FERC’s exclusive ratemaking jurisdiction over wholesale sales of electricity and
the transmission of electricity in interstate commerce. Under the Federal Power Act, FERC has the authority to grant or deny market-based rates for sales of
energy,  capacity,  and  ancillary  services  to  ensure  that  such  sales  are  just  and  reasonable.  FERC’s  jurisdiction  over  ratemaking  includes  the  authority  to
suspend the market-based rates of utilities and set cost-based rates should FERC find that its previous grant of market-based rates authority is no longer
just  and  reasonable.  Other  matters  subject  to  FERC  jurisdiction  include,  but  are  not  limited  to,  third-party  financings;  review  of  mergers;  dispositions  of
jurisdictional facilities and acquisitions of securities of another public utility or an existing operational generating facility; affiliate transactions; intercompany
financings  and  cash  management  arrangements;  certain  internal  corporate  reorganizations;  and  certain  holding  company  acquisitions  of  public  utility  and
holding company securities.

RTOs and ISOs exist in a number of regions to provide transmission service across multiple transmission systems. FERC has approved PJM, MISO, ISO-
NE, and SPP as RTOs and CAISO and NYISO as ISOs. These entities are responsible for regional planning, managing transmission congestion, developing
wholesale  markets  for  energy  and  capacity,  maintaining  reliability,  market  monitoring,  the  scheduling  of  physical  power  sales  brokered  through  ICE  and
NYMEX, and the elimination or reduction of redundant transmission charges imposed by multiple transmission providers when wholesale customers take
transmission  service  across  several  transmission  systems.  ERCOT  is  not  subject  to  regulation  by  FERC  but  performs  a  similar  function  in  Texas  to  that
performed by RTOs in markets regulated by FERC.

Specific operations of Generation are also subject to the jurisdiction of various other Federal, state, regional, and local agencies, including the NRC, and
Federal and state environmental protection agencies. Additionally, Generation is subject to NERC mandatory reliability standards, which protect the nation’s
bulk power system against potential disruptions from cyber and physical security breaches.

Nuclear Facilities

Generation  has  ownership  interests  in  thirteen  nuclear  generating  stations  currently  in  service,  consisting  of  23  units  with  an  aggregate  of  18,880  MW  of
capacity. These stations include FitzPatrick located in Scriba, New York, which was acquired on March 31, 2017 and exclude TMI located in Middletown,
Pennsylvania,  which  permanently  ceased  generation  operations  on  September  20,  2019  and  Oyster  Creek  located  in  Forked  River,  New  Jersey,  which
permanently ceased generation operations on September 17, 2018 and was subsequently sold to Holtec International (Holtec) on July 1, 2019. Generation
wholly  owns  all  of  its  nuclear  generating  stations,  except  for  undivided  ownership  interests  in  three  jointly-owned  nuclear  stations:  Quad  Cities  (75%
ownership),  Peach  Bottom  (50%  ownership),  and  Salem  (42.59%  ownership),  which  are  consolidated  in  Exelon’s  and  Generation's  financial  statements
relative to its proportionate ownership interest in each unit, and a 50.01% membership interest in CENG, a joint venture with EDF, which wholly owns the
Calvert Cliffs and Ginna nuclear stations and Nine Mile Point Unit 1, in addition to an 82% undivided ownership interest in Nine Mile Point Unit 2. CENG is
100% consolidated in Exelon's and Generation's financial statements.

Table of Contents

Generation and EDF entered into a Put Option Agreement on April 1, 2014, pursuant to which EDF has an option to sell its 49.99% equity interest in CENG
to  Generation.  The  put  option  became  exercisable  on  January  1,  2016  and  may  be  exercised  any  time  until  June  30,  2022.  On  November  20,  2019,
Generation  received  notice  of  EDF’s  intention  to  exercise  the  put  option  and  sell  its  ownership  share  in  CENG  to  Generation  and  the  put  automatically
exercised on January 19, 2020 at the end of the sixty-day advance notice period. At this time, Generation cannot reasonably predict the ultimate purchase
price that will be paid to EDF for its interest in CENG. The transaction will require approval by the NYPSC and the FERC. The FERC approval was obtained
on July 30, 2020. From the date the put was exercised, the process and regulatory approvals could take one to two years to complete.

See ITEM 2. PROPERTIES for additional information on Generation's nuclear facilities, Note 2 — Mergers, Acquisitions, and Dispositions of the Combined
Notes to Consolidated Financial Statements for additional information on the disposition of Oyster Creek, and Note 23 — Variable Interest Entities of the
Combined Notes to Consolidated Financial Statements for additional information regarding the CENG consolidation.

Generation’s nuclear generating stations are all operated by Generation, with the exception of the two units at Salem, which are operated by PSEG Nuclear,
LLC  (PSEG  Nuclear),  an  indirect,  wholly  owned  subsidiary  of  PSEG.  In  2020,  2019,  and  2018  electric  supply  (in  GWh)  generated  from  the  nuclear
generating  facilities  was  62%,  64%,  and  68%,  respectively,  of  Generation’s  total  electric  supply,  which  also  includes  fossil,  hydroelectric,  and  renewable
generation and electric supply purchased for resale. Generation’s wholesale and retail power marketing activities are, in part, supplied by the output from the
nuclear generating stations. See ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
for additional information of Generation’s electric supply sources.

Nuclear Operations

Capacity  factors,  which  are  significantly  affected  by  the  number  and  duration  of  refueling  and  non-refueling  outages,  can  have  a  significant  impact  on
Generation’s results of operations. Generation’s operations from its nuclear plants have historically had minimal environmental impact and the plants have a
safe operating history.

Generation manages its scheduled refueling outages to minimize their duration and to maintain high nuclear generating capacity factors, resulting in a stable
generation  base  for  Generation’s  wholesale  and  retail  power  marketing  activities.  During  scheduled  refueling  outages,  Generation  performs  maintenance
and equipment upgrades in order to minimize the occurrence of unplanned outages and to maintain safe, reliable operations. During 2020, 2019, and 2018,
the nuclear generating facilities operated by Generation, achieved capacity factors of 95.4%, 95.7%, and 94.6%, respectively, at ownership percentage.

In addition to the maintenance and equipment upgrades performed by Generation during scheduled refueling outages, Generation has extensive operating
and security procedures in place to ensure the safe operation of the nuclear units. Generation also has extensive safety systems in place to protect the plant,
personnel, and surrounding area in the unlikely event of an accident or other incident.

Regulation of Nuclear Power Generation

Generation is subject to the jurisdiction of the NRC with respect to the operation of its nuclear generating stations, including the licensing for operation of
each  unit.  The  NRC  subjects  nuclear  generating  stations  to  continuing  review  and  regulation  covering,  among  other  things,  operations,  maintenance,
emergency planning, security, and environmental and radiological aspects of those stations. As part of its reactor oversight process, the NRC continuously
assesses  unit  performance  indicators  and  inspection  results  and  communicates  its  assessment  on  a  semi-annual  basis.  All  nuclear  generating  stations
operated  by  Generation  are  categorized  by  the  NRC  in  the  Licensee  Response  Column,  which  is  the  highest  of  five  performance  bands.  The  NRC  may
modify,  suspend,  or  revoke  operating  licenses  and  impose  civil  penalties  for  failure  to  comply  with  the  Atomic  Energy  Act  or  the  terms  of  the  operating
licenses.  Changes  in  regulations  by  the  NRC  may  require  a  substantial  increase  in  capital  expenditures  and/or  operating  costs  for  nuclear  generating
facilities.

Licenses

Generation has original 40-year operating licenses from the NRC for each of its nuclear units and has received 20-year operating license renewals from the
NRC for all its nuclear units except Clinton. PSEG has received 20-year operating license renewals for Salem Units 1 and 2. Peach Bottom has received a
second 20-year license

The operating license renewal process takes approximately four to five years from the commencement of the renewal process, which includes approximately
two years for Generation to develop the application and approximately two years for the NRC to review the application. Depreciation provisions are based on
the estimated useful lives of the stations, which reflect the first renewal of the operating licenses for all of Generation’s operating nuclear generating stations
except for Clinton, Peach Bottom, Byron, and Dresden. Clinton depreciation provisions are based on an estimated useful life of 2027 which is the last year of
the Illinois ZES. Peach Bottom depreciation provisions are based on estimated useful life of 2053 and 2054 for Unit 2 and Unit 3, respectively, which reflects
the second renewal of its operating licenses. Byron and Dresden depreciation provisions are based on the announced shutdown dates of September 2021
and November 2021, respectively. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information

Nuclear Waste Storage and Disposal

There are no facilities for the reprocessing or permanent disposal of SNF currently in operation in the United States, nor has the NRC licensed any such
facilities.  Generation  currently  stores  all  SNF  generated  by  its  nuclear  generating  facilities  on-site  in  storage  pools  or  in  dry  cask  storage  facilities.  Since
Generation’s  SNF  storage  pools  generally  do  not  have  sufficient  storage  capacity  for  the  life  of  the  respective  plant,  Generation  has  developed  dry  cask
storage facilities to support operations.

As  of  December  31,  2020,  Generation  had  approximately  87,100  SNF  assemblies  (21,600  tons)  stored  on  site  in  SNF  pools  or  dry  cask  storage  which
includes SNF assemblies at Zion Station, for which Generation retains ownership even though the responsibility for decommissioning Zion Station has been
assumed  by  another  party,  and  TMI,  which  is  no  longer  operational.  See  the  Decommissioning  section  below  for  additional  information  regarding  Zion
Station. All currently operating Generation-owned nuclear sites have on-site dry cask storage. TMI's on-site dry cask storage is projected to be in operation
in  2021.  On-site  dry  cask  storage  in  concert  with  on-site  storage  pools  will  be  capable  of  meeting  all  current  and  future  SNF  storage  requirements  at
Generation’s sites through the end of the license renewal periods and through decommissioning.

For a discussion of matters associated with Generation’s contracts with the DOE for the disposal of SNF, see Note 19 — Commitments and Contingencies of
the Combined Notes to Consolidated Financial Statements.

As a by-product of their operations, nuclear generating units produce LLRW. LLRW is accumulated at each generating station and permanently disposed of
at  licensed  disposal  facilities.  The  Federal  Low-Level  Radioactive  Waste  Policy  Act  of  1980  provides  that  states  may  enter  into  agreements  to  provide
regional disposal facilities for LLRW and restrict use of those facilities to waste generated within the region. Illinois and Kentucky have entered into such an
agreement, although neither state currently has an operational site and none is anticipated to be operational for the next ten years.

Generation ships its Class A LLRW, which represents 93% of LLRW generated at its stations, to disposal facilities in Utah and South Carolina, which have
enough storage capacity to store all Class A LLRW for the life of all stations in Generation's nuclear fleet. The disposal facility in South Carolina at present is
only receiving LLRW from LLRW generators in South Carolina, New Jersey (which includes Salem), and Connecticut.

Generation utilizes on-site storage capacity at all its stations to store and stage for shipping Class B and Class C LLRW. Generation has a contract through
2032  to  ship  Class  B  and  Class  C  LLRW  to  a  disposal  facility  in  Texas.  The  agreement  provides  for  disposal  of  all  current  Class  B  and  Class  C  LLRW
currently stored at each station as well as the Class B and Class C LLRW generated during the term of the agreement. However, because the production of
LLRW from Generation’s nuclear fleet will exceed the capacity at the Texas site (3.9 million curies for 15 years beginning in 2012), Generation will still be
required to utilize on-site storage at its stations for Class B and Class C LLRW. Generation currently has enough storage capacity to store all Class B and
Class C LLRW for the life of all stations in Generation’s nuclear fleet. Generation continues to pursue alternative disposal strategies for LLRW, including an
LLRW reduction program to minimize on-site storage and cost impacts.

Nuclear Insurance

Generation is subject to liability, property damage, and other risks associated with major incidents at all of its nuclear stations. Generation has reduced its
financial exposure to these risks through insurance and other industry risk-sharing provisions. See “Nuclear Insurance” within Note 19 — Commitments and
Contingencies of the Combined Notes to Consolidated Financial Statements for additional information.

For information regarding property insurance, see ITEM 2. PROPERTIES — Generation. Generation is self-insured to the extent that any losses may exceed
the amount of insurance maintained or are within the policy deductible for its insured losses. Such losses could have a material adverse effect on Exelon’s
and Generation’s future financial statements.

Decommissioning

NRC regulations require that licensees of nuclear generating facilities demonstrate reasonable assurance that funds will be available in specified minimum
amounts at the end of the life of the facility to decommission the facility. The ultimate decommissioning obligation will be funded by the NDT funds. See ITEM
7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF

additional information regarding Generation’s NDT funds and its decommissioning obligations.

Oyster  Creek  Decommissioning.  On  July  1,  2019,  Generation  completed  the  sale  with  Holtec  and  its  indirect  wholly  owned  subsidiary,  Oyster  Creek
Environmental Protection, LLC (OCEP), of Oyster Creek under which Holtec has assumed the responsibility for decommissioning. See Note 2 — Mergers,
Acquisitions, and Dispositions of the Combined Notes to Consolidated Financial Statements for additional information.

Zion  Station  Decommissioning.  On  September  1,  2010,  Generation  completed  an  ASA  with  EnergySolutions,  Inc.  and  its  wholly  owned  subsidiaries,
EnergySolutions,  LLC  and  ZionSolutions  under  which  ZionSolutions  has  assumed  responsibility  for  decommissioning  Zion  Station.  See  Note  10  —  Asset
Retirement Obligations of the Combined Notes to Consolidated Financial Statements for additional information.

Fossil and Renewable Facilities (including Hydroelectric)

Generation wholly owns all of its fossil and renewable generating stations, with the exception of: (1) Wyman; (2) certain wind project entities and a biomass
project entity with minority interest owners; and (3) EGRP which is owned 49% by another owner. See Note 23 — Variable Interest Entities of the Combined
Notes to Consolidated Financial Statements for additional information regarding EGRP which is a VIE. Generation’s fossil and renewable generating stations
are  all  operated  by  Generation,  with  the  exception  of  Wyman,  which  is  operated  by  a  third  party.  In  2020,  2019,  and  2018,  electric  supply  (in  GWh)
generated from owned fossil and renewable generating facilities was 9%, 11%, and 11%, respectively, of Generation’s total electric supply. The majority of
this  output  was  dispatched  to  support  Generation’s  wholesale  and  retail  power  marketing  activities.  On  December  8,  2020,  Generation  entered  into  an
agreement to sell a significant portion of Generation's solar business. See ITEM 2. PROPERTIES for additional information regarding Generation's electric
generating  facilities  and  Note  2  -  Mergers,  Acquisitions  and  Dispositions  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional
information on the sale of Generation's solar business.

Licenses

Fossil and renewable generation plants are generally not licensed, and, therefore, the decision on when to retire plants is, fundamentally, a commercial one.
FERC has the exclusive authority to license most non-Federal hydropower projects located on navigable waterways or Federal lands, or connected to the
interstate electric grid, which include Generation's Conowingo Hydroelectric Project (Conowingo) and Muddy Run Pumped Storage Facility Project (Muddy
Run). Muddy Run's license expires on December 1, 2055. On August 29, 2012, Generation submitted a hydroelectric license application to the FERC for a
new license for Conowingo. Based on the FERC procedural schedule, the FERC licensing process for Conowingo was not completed prior to the expiration
of  the  plant’s  license  on  September  1,  2014.  As  a  result,  on  September  10,  2014,  FERC  issued  an  annual  license  for  Conowingo,  effective  as  of  the
expiration of the previous license. The annual license renews automatically absent any further FERC action. The stations are currently being depreciated
over their estimated useful lives, which include actual and anticipated license renewal periods. See Note 3 — Regulatory Matters of the Combined Notes to
Consolidated Financial Statements for additional information on Conowingo.

Insurance

Generation maintains business interruption insurance for its renewable projects, but not for its fossil and hydroelectric operations unless required by contract
or  financing  agreements.  See  Note  17  —  Debt  and  Credit  Agreements  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional
information on financing agreements. Generation maintains both property damage and liability insurance. For property damage and liability claims for these
operations, Generation is self-insured to the extent that losses are within the policy deductible or exceed the amount of insurance maintained. Such losses
could have a material adverse effect on Exelon’s and Generation’s future financial conditions and their results of operations and cash flows. For information
regarding property insurance, see ITEM 2. PROPERTIES — Generation.

Includes the proportionate share of output where Generation has an undivided ownership interest in jointly-owned generating plants and includes the total output of plants
that are fully consolidated (e.g., CENG).  Nuclear generation for 2020 and 2019 includes physical volumes of 35,052 GWh and 35,745 GWh, respectively, for CENG.
Includes wind, hydroelectric, solar, and biomass generating assets.

(b)

The cycle of production and utilization of nuclear fuel includes the mining and milling of uranium ore into uranium concentrates, the conversion of uranium
concentrates  to  uranium  hexafluoride,  the  enrichment  of  the  uranium  hexafluoride,  and  the  fabrication  of  fuel  assemblies.  Generation  has  inventory  in
various forms and does not anticipate difficulty in obtaining the necessary uranium concentrates or conversion, enrichment, or fabrication services to meet
the nuclear fuel requirements of its nuclear units.

Natural gas is procured through long-term and short-term contracts, as well as spot-market purchases. Fuel oil inventories are managed so that in the winter
months sufficient volumes of fuel are available in the event of extreme weather conditions and during the remaining months to take advantage of favorable
market pricing.

Generation uses financial instruments to mitigate price risk associated with certain commodity price exposures, using both over-the-counter and exchange-
traded instruments. See ITEM 1A. RISK FACTORS, ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF  OPERATIONS,  Critical  Accounting  Policies  and  Estimates  and  Note  16  —  Derivative  Financial  Instruments  of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information regarding derivative financial instruments.

Table of Contents

Power Marketing

Generation’s  integrated  business  operations  include  physical  delivery  and  marketing  of  power.  Generation  largely  obtains  physical  power  supply  from  its
owned and contracted generation in multiple geographic regions. The commodity risks associated with the output from owned and contracted generation is
managed  using  various  commodity  transactions  including  sales  to  customers.  The  main  objective  is  to  obtain  low-cost  energy  supply  to  meet  physical
delivery  obligations  to  both  wholesale  and  retail  customers.  Generation  sells  electricity,  natural  gas,  and  other  energy  related  products  and  solutions  to
various  customers,  including  distribution  utilities,  municipalities,  cooperatives,  and  commercial,  industrial,  governmental,  and  residential  customers  in
competitive markets. Where necessary, Generation may also purchase transmission service to ensure that it has reliable transmission capacity to physically
move its power supplies to meet customer delivery needs.

Price and Supply Risk Management

Generation  also  manages  the  price  and  supply  risks  for  energy  and  fuel  associated  with  generation  assets  and  the  risks  of  power  marketing  activities.
Generation implements a three-year ratable sales plan to align its hedging strategy with its financial objectives. Generation may also enter into transactions
that are outside of this ratable sales plan. Generation is exposed to commodity price risk in 2021 and beyond for portions of its electricity portfolio that are
unhedged.  As  of  December  31,  2020,  the  percentage  of  expected  generation  hedged  for  the  Mid-Atlantic,  Midwest,  New  York,  and  ERCOT  reportable
segments  is  94%-97%  for  2021.  The  percentage  of  expected  generation  hedged  is  the  amount  of  equivalent  sales  divided  by  the  expected  generation.
Expected generation is the volume of energy that best represents our commodity position in energy markets from owned or contracted generation based
upon a simulated dispatch model that makes assumptions regarding future market conditions, which are calibrated to market quotes for power, fuel, load
following  products,  and  options.  Equivalent  sales  represent  all  hedging  products,  which  include  economic  hedges  and  certain  non-derivative  contracts,
including sales to the Utility Registrants to serve their retail load. A portion of Generation’s hedging strategy may be implemented through the use of fuel
products based on assumed correlations between power and fuel prices. The risk management group and Exelon’s RMC monitor the financial risks of the
wholesale  and  retail  power  marketing  activities.  Generation  also  uses  financial  and  commodity  contracts  for  proprietary  trading  purposes,  but  this  activity
accounts for only a small portion of Generation’s efforts. The proprietary trading portfolio is subject to a risk management policy that includes stringent risk
management limits. See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK for additional information.

Capital Expenditures

Generation’s business is capital intensive and requires significant investments primarily in nuclear fuel and energy generation assets. Generation’s estimated
capital expenditures for 2021 include Generation's share of the investment in the co-owned Salem plant and the total capital expenditures for CENG. See
ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS,  Liquidity  and  Capital
Resources, for additional information regarding projected 2021 capital expenditures.

Utility Registrants

Merger with Pepco Holdings, Inc.

On March 23, 2016, Exelon completed the merger among Exelon, Purple Acquisition Corp., a wholly owned subsidiary of Exelon (Merger Sub), and PHI. As
a result of that merger, Merger Sub was merged into PHI (the PHI merger) with PHI surviving as a wholly owned subsidiary of Exelon and EEDC, a wholly
owned  subsidiary  of  Exelon  which  also  owns  Exelon's  interests  in  ComEd,  PECO,  and  BGE  (through  a  special  purpose  subsidiary  in  the  case  of  BGE).
Following the completion of the PHI merger, Exelon, and PHI completed a series of internal corporate organization restructuring transactions resulting in the
transfer of PHI’s unregulated business interests to Exelon and Generation and the transfer of PHI, Pepco, DPL, and ACE to a special purpose subsidiary of
EEDC.

The  Utility  Registrants  have  the  necessary  authorizations  to  perform  their  current  business  of  providing  regulated  electric  and  natural  gas  distribution
services in the various municipalities and territories in which they now supply such services. These authorizations include charters, franchises, permits, and
certificates of public convenience issued by local and state governments and state utility commissions. ComEd's, BGE's (gas), Pepco DC's, and ACE's rights
are generally non-exclusive while PECO's, BGE's (electric), Pepco MD's, and DPL's rights are generally exclusive. Certain authorizations are perpetual while
others  have  varying  expiration  dates.  The  Utility  Registrants  anticipate  working  with  the  appropriate  governmental  bodies  to  extend  or  replace  the
authorizations prior to their expirations.

Utility Regulations

State  utility  commissions  regulate  the  Utility  Registrants'  electric  and  gas  distribution  rates  and  service,  issuances  of  certain  securities,  and  certain  other
aspects of the business. The following table outlines the state commissions responsible for utility oversight.

The Utility Registrants are public utilities under the Federal Power Act subject to regulation by FERC related to transmission rates and certain other aspects
of the utilities' business. The U.S. Department of Transportation also regulates pipeline safety and other areas of gas operations for PECO, BGE, and DPL.
Additionally,  the  Utility  Registrants  are  subject  to  NERC  mandatory  reliability  standards,  which  protect  the  nation's  bulk  power  system  against  potential
disruptions from cyber and physical security breaches.

Table of Contents

Seasonality Impacts on Delivery Volumes

The Utility Registrants' electric distribution volumes are generally higher during the summer and winter months when temperature extremes create demand
for either summer cooling or winter heating. For PECO, BGE, and DPL, natural gas distribution volumes are generally higher during the winter months when
cold temperatures create demand for winter heating.

ComEd, BGE, Pepco, and DPL Maryland have electric distribution decoupling mechanisms and BGE has a natural gas decoupling mechanism that eliminate
the  favorable  and  unfavorable  impacts  of  weather  and  customer  usage  patterns  on  electric  distribution  and  natural  gas  delivery  volumes.  As  a  result,
ComEd's,  BGE's,  Pepco's,  and  DPL's  Maryland  electric  distribution  revenues  and  BGE's  natural  gas  distribution  revenues  are  not  materially  impacted  by
delivery volumes. PECO's and DPL's Delaware electric distribution revenues and natural gas distribution revenues and ACE's electric distribution revenues
are impacted by delivery volumes.

Electric and Natural Gas Distribution Services

The Utility Registrants are allowed to recover reasonable costs and fair and prudent capital expenditures associated with electric and natural gas distribution
services  and  earn  a  return  on  those  capital  expenditures,  subject  to  commission  approval.  ComEd  recovers  costs  through  a  performance-based  rate
formula.  ComEd  is  required  to  file  an  update  to  the  performance-based  rate  formula  on  an  annual  basis.  PECO's,  BGE's,  and  DPL's  electric  and  gas
distribution costs and Pepco's and ACE's electric distribution costs have generally been recovered through traditional rate case proceedings. However, the
MDPSC  and  the  DCPSC  allow  utilities  to  file  multi-year  rate  plans.  In  certain  instances,  the  Utility  Registrants  use  specific  recovery  mechanisms  as
approved by their respective regulatory agencies.

ComEd, Pepco, and ACE customers have the choice to purchase electricity, and PECO, BGE, and DPL customers have the choice to purchase electricity
and  natural  gas  from  competitive  electric  generation  and  natural  gas  suppliers.  The  Utility  Registrants  remain  the  distribution  service  providers  for  all
customers  and  are  obligated  to  deliver  electricity  and  natural  gas  to  customers  in  their  respective  service  territories  while  charging  a  regulated  rate  for
distribution service. In addition, the Utility Registrants also retain significant default service obligations to provide electricity to certain groups of customers in
their respective service areas who do not choose a competitive electric generation supplier. PECO and BGE also retain significant default service obligations
to provide natural gas to certain groups of customers in their respective service areas who do not choose a competitive natural gas supplier. For natural gas,
DPL does not retain default service obligations for its residential customers.

For  customers  that  choose  to  purchase  electric  generation  or  natural  gas  from  competitive  suppliers,  the  Utility  Registrants  act  as  the  billing  agent  and
therefore do not record Operating revenues or Purchased power and fuel expense related to the electricity and/or natural gas. For customers that choose to
purchase  electric  generation  or  natural  gas  from  a  Utility  Registrant,  the  Utility  Registrants  are  permitted  to  recover  the  electricity  and  natural  gas
procurement  costs  without  mark-up  and  therefore  record  equal  and  offsetting  amounts  of  Operating  revenues  and  Purchased  power  and  fuel  expense
related to the electricity and/or natural gas. As a result, fluctuations in electricity or natural gas sales and procurement costs have no impact on the Utility
Registrants’ Net Income.

See ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, Results of Operations and
Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  regarding  electric  and  natural  gas
distribution services.

Procurement of Electricity and Natural Gas

The Utility Registrants' electric supply for its customers is primarily procured through contracts as required by their respective state commissions. The Utility
Registrants procure electricity supply from various approved bidders, including Generation. RTO spot market purchases and sales are utilized to balance the
utility electric load and supply as required. Charges incurred for electric supply procured through contracts with Generation are included in Purchased power
from affiliates on the Utility Registrants' Statements of Operations and Comprehensive Income.

PECO's,  BGE’s,  and  DPL's  natural  gas  supplies  are  purchased  from  a  number  of  suppliers  for  terms  of  up  to  three  years.  PECO,  BGE,  and  DPL  have
annual firm supply and transportation contracts of 132,000 mmcf, 264,000 mmcf and 61,000 mmcf, respectively. In addition, to supplement gas supply at
times  of  heavy  winter  demands  and  in  the  event  of  temporary  emergencies,  PECO,  BGE,  and  DPL  have  available  storage  capacity  from  the  following
sources:

(a) Natural  gas  from  underground  storage  represents  approximately  28%,  20%,  and  33%  of  PECO's,  BGE’s,  and  DPL's  2020-2021  heating  season  planned  supplies,

respectively.

PECO, BGE, and DPL have long-term interstate pipeline contracts and also participate in the interstate markets by releasing pipeline capacity or bundling
pipeline capacity with gas for off-system sales. Off-system gas sales are low-margin direct sales of gas to wholesale suppliers of natural gas. Earnings from
these activities are shared between the utilities and customers. PECO, BGE, and DPL make these sales as part of a program to balance its supply and cost
of natural gas. The off-system gas sales are not material to PECO, BGE, and DPL.

See  ITEM  7A.  QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET  RISK,  Commodity  Price  Risk  (All  Registrants),  for  additional
information regarding Utility Registrants' contracts to procure electric supply and natural gas.

Energy Efficiency Programs

The  Utility  Registrants  are  generally  allowed  to  recover  costs  associated  with  the  energy  efficiency  and  demand  response  programs  they  offer.  Each
commission approved program seeks to meet mandated electric consumption reduction targets and implement demand response measures to reduce peak
demand. The programs are designed to meet standards required by each respective regulatory agency.

ComEd  is  allowed  to  earn  a  return  on  its  energy  efficiency  costs.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial
Statements for additional information.

Capital Investment

The Utility Registrants' businesses are capital intensive and require significant investments, primarily in electric transmission and distribution and natural gas
transportation  and  distribution  facilities,  to  ensure  the  adequate  capacity,  reliability,  and  efficiency  of  their  systems.  See  ITEM  7.  MANAGEMENT'S
DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, Liquidity and Capital Resources, for additional information
regarding projected 2021 capital expenditures.

Transmission Services

Under  FERC’s  open  access  transmission  policy,  the  Utility  Registrants,  as  owners  of  transmission  facilities,  are  required  to  provide  open  access  to  their
transmission facilities under filed tariffs at cost-based rates approved by FERC. The Utility Registrants and their affiliates are required to comply with FERC’s
Standards  of  Conduct  regulation  governing  the  communication  of  non-public  transmission  information  between  the  transmission  owner’s  employees  and
wholesale merchant employees.

PJM is the regional grid operator and operates pursuant to FERC-approved tariffs. PJM is the transmission provider under, and the administrator of, the PJM
Open Access Transmission Tariff (PJM Tariff). PJM operates the PJM energy, capacity, and other markets, and, through central dispatch, controls the day-to-
day operations of the bulk power system for the region. The Utility Registrants are members of PJM and provide regional transmission service pursuant to
the PJM Tariff. The Utility Registrants and the other transmission owners in PJM have turned over control of certain of their transmission facilities to PJM,
and their transmission systems are under the dispatch control of PJM. Under the PJM Tariff, transmission service is provided on a region-wide, open-

The Registrants strive to create a workplace that is diverse, innovative, and safe for their employees. In order to provide the services and products that their
customers  expect,  the  Registrants  must  create  the  best  teams.  These  teams  must  reflect  the  diversity  of  the  communities  that  the  Registrants  serve.
Therefore, the Registrants strive to attract highly qualified and diverse talent and routinely review their hiring and promotion practices to ensure they maintain
equitable and bias free processes to neutralize any unconscious bias. The Registrants provide growth opportunities, competitive compensation and benefits,
and  a  variety  of  training  and  development  programs.  The  Registrants  are  committed  to  helping  employees  grow  their  skills  and  careers  largely  through
numerous  training  opportunities  in  technical,  safety  and  business  acumen  areas,  mentorship  programs,  and  continuous  feedback  and  development
discussions and evaluations. Employees are encouraged to thrive outside the workplace as well. The Registrants provide a full suite of wellness benefits
targeted at supporting work-life balance, physical, mental and financial health, and industry-leading paid leave policies.

The  Registrants  conduct  an  employee  engagement  survey  every  other  year  to  help  identify  their  successes  and  areas  where  they  can  grow.  The  survey
results are reviewed with senior management and the Exelon Board of Directors.

Environmental Regulation

General

The  Registrants  are  subject  to  comprehensive  and  complex  environmental  legislation  and  regulation  at  the  federal,  state,  and  local  levels,  including
requirements relating to climate change, air and water quality, solid and hazardous waste, and impacts on species and habitats.

The  Exelon  Board  of  Directors  is  responsible  for  overseeing  the  management  of  environmental  matters.  Exelon  has  a  management  team  to  address
environmental compliance and strategy, including the CEO; the Senior Vice President, Corporate Strategy & Chief Innovation and Sustainability Officer; the
Senior  Vice  President,  Competitive  Market  Policy;  and  the  Vice  President,  Corporate  Environmental  Strategy,  as  well  as  senior  management  of  the
Registrants. Performance of those individuals directly involved in environmental compliance and strategy is reviewed and affects compensation as part of the
annual individual performance review process. The Exelon Board of Directors has delegated to its Generation Oversight Committee and the Corporate

20

Table of Contents

Governance  Committee  the  authority  to  oversee  Exelon’s  compliance  with  health,  environmental,  and  safety  laws  and  regulations  and  its  strategies  and
efforts  to  protect  and  improve  the  quality  of  the  environment,  including  Exelon’s  internal  climate  change  and  sustainability  policies  and  programs,  as
discussed  in  further  detail  below.  The  respective  Boards  of  the  Utility  Registrants  oversee  environmental,  health,  and  safety  issues  related  to  these
companies.

Climate Change Mitigation

Exelon  supports  comprehensive  federal  climate  legislation,  including  a  cap-and-trade  program  for  GHG  emissions  that  addresses  the  urgent  need  to
substantially  reduce  national  GHG  emissions  while  providing  appropriate  protections  for  consumers,  businesses,  and  the  economy.  In  the  absence  of
comprehensive federal legislation, Exelon supports EPA moving forward with meaningful regulation of GHG emissions under the Clean Air Act.

The  Registrants  currently  are  subject  to,  and  may  become  subject  to  additional,  federal  and/or  state  legislation  and/or  regulations  addressing  GHG
emissions. Generation produces electricity predominantly from low- and zero-carbon generating facilities (such as nuclear, hydroelectric, natural gas, wind,
and solar PV) and neither owns nor operates any coal-fueled generating assets. Generation’s natural gas and biomass fired generating plants produce GHG
emissions,  most  notably  CO2.  However,  Generation’s  owned-asset  emission  intensity,  or  rate  of  carbon  dioxide  equivalent  (CO e)  emitted  per  unit  of
electricity generated, is among the lowest in the industry.

2

Other GHG emission sources associated with the Utility Registrants include natural gas (methane) leakage on the natural gas systems, sulfur hexafluoride
(SF6) leakage from electric transmission and distribution operations, refrigerant leakage from chilling and cooling equipment, and fossil fuel combustion in
motor vehicles. In addition, PECO, BGE, and DPL distribute natural gas and Generation sells natural gas at retail; and consumers’ use of such natural gas
produces GHG emissions.

International Climate Change Agreements. At the international level, the United States is a party to the United Nations Framework Convention on Climate
Change (UNFCCC). The Parties to the UNFCCC adopted the Paris Agreement at the 21st session of the UNFCCC Conference of the Parties (COP 21) on
December  12,  2015.  Under  the  Agreement,  which  became  effective  on  November  4,  2016,  the  parties  committed  to  try  to  limit  the  global  average
temperature  increase  and  to  develop  national  GHG  reduction  commitments.  On  November  4,  2020,  the  United  States  formally  withdrew  from  the  Paris
Agreement, retracting its commitment to reduce domestic GHG emissions by 26%-28% by 2025 compared with 2005 levels. However, on January 20, 2021,
President  Biden  accepted  the  Paris  Agreement,  which  resulted  in  the  United  States’  formal  re-entry  on  February  19,  2021.  The  Biden  administration  has
announced its intent to pursue ambitious GHG reductions in the United States and internationally.

Federal  Climate  Change  Legislation  and  Regulation.  It  is  highly  uncertain  whether  federal  legislation  to  significantly  reduce  GHG  emissions  will  be
enacted in the near-term. If such legislation were adopted, it would likely increase the value of Exelon's low-carbon fleet even though Exelon may incur costs
either  to  further  limit  or  offset  the  GHG  emissions  from  its  operations  or  to  procure  emission  allowances  or  credits.  Continued  inaction  could  negatively
impact the value of Exelon’s low-carbon fleet.

The Clean Power Plan and Affordable Clean Energy Rule. The EPA’s 2015 Clean Power Plan (CPP) established regulations addressing carbon dioxide
emissions from existing fossil-fired power plants under Clean Air Act Section 111(d). The CPP’s carbon pollution limits could be met through changes to the
electric  generation  system,  including  shifting  generation  from  higher-emitting  units  to  lower-  or  zero-emitting  units,  as  well  as  the  development  of  new  or
expanded zero-emissions generation. In July 2019, the EPA published its final Affordable Clean Energy rule, which repealed the CPP and replaced it with
less stringent emissions guidelines for existing fossil-fired power plants based on heat rate improvement measures that could be achieved within the fence
line  of  individual  plants.  Exelon,  together  with  a  coalition  of  other  electric  utilities,  filed  a  lawsuit  in  the  U.S.  Court  of  Appeals  for  the  D.C.  Circuit  on
September  6,  2019,  challenging  the  Affordable  Clean  Energy  rule  as  unlawful.  This  lawsuit  was  consolidated  with  separate  challenges  to  the  Affordable
Clean Energy rule filed by various states, non-governmental organizations, and business coalitions. On January 19, 2021, the U.S. Court of Appeals for the
D.C. Circuit held the Affordable Clean Energy Rule to be unlawful, vacated the rule, and remanded it to the EPA. The EPA has indicated it will promulgate
new GHG limits for existing power plants in accordance with the U.S. Court of Appeals for the D.C. Circuit's order.

State Climate Change Legislation and Regulation. A number of states in which the Registrants operate have state and regional programs to reduce GHG
emissions and renewable and other portfolio standards, which impact the power sector. See discussion below for additional information on renewable and
other  portfolio  standards.  As  the  nation’s  largest  generator  of  carbon-free  electricity,  Generation’s  fleet  supports  these  efforts  to  produce  safe,  reliable
electricity with minimal GHGs.

Eleven northeast and mid-Atlantic states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island,
Vermont, and Virginia) currently participate in the RGGI, which is in the process of strengthening its requirements. The program requires most fossil fuel-fired
power plants in the region to hold allowances, purchased at auction, for each ton of CO2 emissions. Non-emitting resources do not have to purchase or hold
these allowances. In October 2019, the Governor of Pennsylvania issued an Executive Order directing the PA DEP to begin a rulemaking process to allow
Pennsylvania to join the RGGI, with the goal of reducing carbon emissions from the electricity sector. On November 7, 2020, the PA DEP proposed its rule.

Broader state programs impact other sectors as well, such as New York’s Climate Leadership and Community Protection Act, which establishes statewide
emission limits; and Massachusetts’ Clean Energy and Climate Plan, which aims to reduce GHG emissions across all sectors through increased efficiency in
buildings  and  vehicles,  the  electrification  of  vehicles  and  thermal  conditioning  in  buildings,  and  the  replacement  of  carbon  intensive  fuels  with  renewable
energy sources.

While the Registrants cannot predict the nature of future regulations or how such regulations might impact future financial statements, Generation has a low
emission portfolio, and GHG restrictions would likely benefit zero- and low-emission generating units relative to higher-emission fossil fuel-fired generating
units.

In addition, Exelon facilities and operations are subject to the global impacts of climate change. Exelon believes its operations could be significantly affected
by the physical risks of climate change. See ITEM 1A. RISK FACTORS for additional information.

Renewable and Clean Energy Standards

Thirty states and the District of Columbia, incorporating the vast majority of states where Exelon operates, have adopted some form of renewable or clean
energy  procurement  requirement.  These  standards  impose  varying  levels  of  mandates  for  procurement  of  renewable  or  clean  electricity  (the  definition  of
which varies by state) and/or energy efficiency. These are generally expressed as a percentage of annual electric load, often increasing by year. The Utility
Registrants comply with these various requirements through purchasing qualifying renewables, implementing efficiency programs, acquiring sufficient credits
(e.g.,  RECs),  paying  an  alternative  compliance  payment,  and/or  a  combination  of  these  compliance  alternatives.  The  Utility  Registrants  are  permitted  to
recover  from  retail  customers  the  costs  of  complying  with  their  state  RPS  requirements,  including  the  procurement  of  RECs  or  other  alternative  energy
resources. Illinois, New York, and New Jersey adopted standards targeted at preserving the zero-carbon attributes of certain nuclear-powered generating
facilities.  Generation  owns  multiple  facilities  participating  in  these  programs  within  these  states.  Other  states  in  which  Exelon  operates  are  considering
similar programs.

See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

Air Quality

Mercury and Air Toxics Standards (MATS). In 2011, the EPA signed a final rule, known as MATS, to reduce emissions of hazardous air pollutants from
power  plants.  MATS  requires  coal-fired  power  plants  to  achieve  high  removal  rates  of  mercury,  acid  gases,  and  other  metals,  and  to  make  capital
investments  in  pollution  control  equipment  and  incur  higher  operating  expenses.  In  2016,  in  response  to  a  Supreme  Court  decision  requiring  the  EPA  to
consider  costs  in  determining  whether  it  was  appropriate  and  necessary  to  regulate  power  plant  emissions  of  hazardous  air  pollutants,  the  EPA  issued  a
supplemental finding that, after considering costs, it remained appropriate and necessary. On May 22, 2020, the EPA reversed course, publishing a final rule
revoking the "appropriate and necessary" finding underpinning MATS. A coal mining company filed a lawsuit in the U.S. Court of Appeals for the D.C. Circuit
seeking vacatur of MATS based on the EPA’s May 22, 2020 finding; on September 11, 2020, the U.S. Court of Appeals for the D.C. Circuit granted a motion
by Exelon and two other

22

Table of Contents

entities to intervene in that lawsuit to defend MATS, and on September 28, 2020, the U.S. Court of Appeals for the D.C. Circuit issued an Executive Order
holding this portion of the MATS litigation in abeyance. On July 21, 2020, Exelon and two other entities filed a lawsuit in the U.S. Court of Appeals for the
D.C. Circuit challenging the EPA’s May 22, 2020 rescission of the appropriate and necessary finding underpinning MATS. This portion of the case is also
being held in abeyance in response to the DOJ’s motion filed February 12, 2021. On January 20, 2021, President Biden issued an Executive Order directing
the EPA to reconsider its May 22, 2020 recission by August 2021; the EPA will likely re-affirm the finding that it is appropriate and necessary to regulate
power plant emissions of hazardous air pollutants. As a result, this litigation is likely to be rendered moot, and MATS will likely remain in place in the interim.

Water Quality

Under the federal Clean Water Act, NPDES permits for discharges into waterways are required to be obtained from the EPA or from the state environmental
agency  to  which  the  permit  program  has  been  delegated,  and  permits  must  be  renewed  periodically.  Certain  of  Exelon's  facilities  discharge  stormwater,
industrial wastewater, and/or cooling water into waterways and are therefore subject to these regulations and operate under NPDES permits.

Clean Water Act Section 316(b) is implemented through the NDPES program and requires that the cooling water intake structures at electric power plants
reflect the best technology available to minimize adverse environmental impacts. Generation’s power generation facilities with cooling water intake systems
are subject to the EPA’s Section 316(b) regulations finalized in 2014; the regulation’s requirements have been or will be addressed through renewal of these
facilities’ NPDES permits. Until the compliance requirements are determined by the applicable state permitting director on a site-specific basis for each plant,
Generation  cannot  estimate  the  effect  that  compliance  with  the  EPA’s  2014  rule  will  have  on  the  operation  of  its  generating  facilities  and  its  financial
statements.  Should  a  state  permitting  director  determine  that  a  facility  must  install  cooling  towers  to  comply  with  the  rule,  that  facility’s  economic  viability
could be called into question. However, the final rule does not mandate cooling towers and allows state permitting directors to require alternative, less costly
technologies and/or operational measures, based on a site-specific assessment of the feasibility, costs, and benefits of available options.

On July 28, 2016, the NJDEP issued a final permit for Salem that did not require the installation of cooling towers and allows Salem to continue to operate
utilizing  the  existing  cooling  water  system  with  certain  required  system  modifications.  However,  the  permit  is  being  challenged  by  an  environmental
organization, and if successful, could result in additional costs for Clean Water Act compliance. Potential cooling water system modification costs could be
material and could adversely impact the economic competitiveness of this facility.

Under Clean Water Act Section 404 and state laws and regulations, the Registrants may be required to obtain permits for projects involving dredge or fill
activities in Waters of the United States.

Where Registrants’ facilities are required to secure a federal license or permit for activities that may result in a discharge to covered waters, they may be
required to obtain a state water quality certification under Clean Water Act section 401.

Generation is also subject to the jurisdiction of the Delaware River Basin Commission and the Susquehanna River Basin Commission, regional agencies that
primarily regulate water usage.

Solid and Hazardous Waste and Environmental Remediation

CERCLA provides for response and removal actions coordinated by the EPA in the event of threatened releases of hazardous substances and authorizes
the EPA either to clean up sites at which hazardous substances have created actual or potential environmental hazards or to order persons responsible for
the  situation  to  do  so.  Under  CERCLA,  generators  and  transporters  of  hazardous  substances,  as  well  as  past  and  present  owners  and  operators  of
hazardous waste sites, are strictly, jointly and severally liable for the cleanup costs of hazardous waste at sites, many of which are listed by the EPA on the
National  Priorities  List  (NPL).  These  PRPs  can  be  ordered  to  perform  a  cleanup,  can  be  sued  for  costs  associated  with  an  EPA-directed  cleanup,  may
voluntarily  settle  with  the  EPA  concerning  their  liability  for  cleanup  costs,  or  may  voluntarily  begin  a  site  investigation  and  site  remediation  under  state
oversight. Most states have also enacted statutes that contain provisions substantially similar to CERCLA. Such statutes apply in many states where the
Registrants currently own or

23

Table of Contents

operate, or previously owned or operated, facilities, including Delaware, Illinois, Maryland, New Jersey, and Pennsylvania and the District of Columbia. In
addition, RCRA governs treatment, storage and disposal of solid and hazardous wastes and cleanup of sites where such activities were conducted.

The  Registrants’  operations  have  in  the  past,  and  may  in  the  future,  require  substantial  expenditures  in  order  to  comply  with  these  Federal  and  state
environmental laws. Under these laws, the Registrants may be liable for the costs of remediating environmental contamination of property now or formerly
owned by them and of property contaminated by hazardous substances generated by them. The Registrants own or lease a number of real estate parcels,
including parcels on which their operations or the operations of others may have resulted in contamination by substances that are considered hazardous
under  environmental  laws.  The  Registrants  and  their  subsidiaries  are,  or  could  become  in  the  future,  parties  to  proceedings  initiated  by  the  EPA,  state
agencies, and/or other responsible parties under CERCLA and RCRA or similar state laws with respect to a number of sites or may undertake to investigate
and remediate sites for which they may be subject to enforcement actions by an agency or third-party.

ComEd’s  and  PECO’s  environmental  liabilities  primarily  arise  from  contamination  at  former  MGP  sites.  ComEd,  pursuant  to  an  ICC  order,  and  PECO,
pursuant to settlements of natural gas distribution rate cases with the PAPUC, have an on-going process to recover environmental remediation costs of the
MGP  sites  through  a  provision  within  customer  rates.  BGE,  ACE,  Pepco,  and  DPL  do  not  have  material  contingent  liabilities  relating  to  MGP  sites.  The
amount to be expended in 2021 for compliance with environmental remediation related to contamination at former MGP sites and other gas purification sites
is estimated to be approximately $35 million which consists primarily of $30 million at ComEd.

As  of  December  31,  2020,  the  Registrants  have  established  appropriate  contingent  liabilities  for  environmental  remediation  requirements.  In  addition,  the
Registrants may be required to make significant additional expenditures not presently determinable for other environmental remediation costs.

See  Note  3  —  Regulatory  Matters  and  Note  19  —  Commitments  and  Contingencies  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information regarding the Registrants’ environmental matters, remediation efforts, and related impacts to the Registrants’ Consolidated Financial
Statements.

Each of the Registrants operates in a complex market and regulatory environment that involves significant risks, many of which are beyond that Registrant’s
direct control. Such risks, which could negatively affect one or more of the Registrants’ consolidated financial statements, fall primarily under the categories
below:

Market and Financial Factors primarily include:

•

•

•

the price of fuels, in particular the price of natural gas, which affects power prices,

the generation resources in the markets in which the Registrants operate,

the demand for electricity, reliability of service, and affordability in the markets where the Registrants conduct their business,

30

Table of Contents

•

•

•

the ability of the Registrants to operate their respective generating and transmission and distribution assets, their ability to access capital markets,
and the impacts on their results of operations due to the global outbreak (pandemic) of the 2019 novel coronavirus (COVID-19),

the impacts of on-going competition, and

emerging technologies and business models, including those related to climate change mitigation and transition to a low carbon economy.

Regulatory, Legislative, and Legal Factors primarily include changes to, and compliance with, the laws and regulations that govern:

•

•

•

•

•

the design of power markets,

ZEC programs,

utility regulatory business models,

environmental and climate policy, and

tax policy.

Operational Factors primarily include:

•

•

•

•

changes in the global climate could produce extreme weather events, which could put the Registrant’s facilities at risk, and such changes could also
affect the levels and patterns of demand for energy and related services,

the  safe,  secure,  and  effective  operation  of  Generation’s  nuclear  facilities  and  the  ability  to  effectively  manage  the  associated  decommissioning
obligations,

the ability of the Registrants to maintain the reliability, resiliency, and safety of their energy delivery systems, which could affect the operating costs
of the Registrants and the opinions of their customers and regulators, and

physical  and  cyber  security  risks  for  the  Registrants  as  the  owner-operators  of  generation,  transmission,  and  distribution  facilities  and  as
participants in commodities trading.

Risks Related to the Planned Separation primarily include:

•

•

•

the timing and conditions associated with required regulatory approvals, which may affect the costs to achieve the separation and its timing,

challenges to achieving the benefits of separation, including maintaining investment grade credit ratings, and

the risk that the separation could be treated as a taxable transaction to both Exelon and its shareholders.

There  may  be  further  risks  and  uncertainties  that  are  not  presently  known  or  that  are  not  currently  believed  by  the  Registrants  to  be  material  that  could
negatively affect its consolidated financial statements in the future.

Market and Financial Factors

Generation  is  exposed  to  price  volatility  associated  with  both  the  wholesale  and  retail  power  markets  and  the  procurement  of
nuclear and fossil fuel (Exelon and Generation).

Generation is exposed to commodity price risk for the unhedged portion of its electricity generation supply portfolio. Generation’s earnings and cash flows
are therefore exposed to variability of spot and forward market prices in the markets in which it operates.

31

Table of Contents

Price of Fuels. The spot market price of electricity for each hour is generally determined by the marginal cost of supplying the next unit of electricity to the
market during that hour. Thus, the market price of power is affected by the market price of the marginal fuel used to generate the electricity unit.

Demand  and  Supply.  The  market  price  for  electricity  is  also  affected  by  changes  in  the  demand  for  electricity  and  the  available  supply  of
electricity. Unfavorable economic conditions, milder than normal weather, and the growth of energy efficiency and demand response programs could each
depress  demand.  In  addition,  in  some  markets,  the  supply  of  electricity  could  often  exceed  demand  during  some  hours  of  the  day,  resulting  in  loss  of
revenue  for  base-load  generating  plants  such  as  Generation's  nuclear  plants.  Conversely,  new  demand  sources  such  as  electrification  of  transportation
could increase demand and change demand patterns.

Retail Competition. Generation’s retail operations compete for customers in a competitive environment, which affects the margins that Generation can earn
and the volumes that it is able to serve. In periods of sustained low natural gas and power prices and low market volatility, retail competitors can aggressively
pursue  market  share  because  the  barriers  to  entry  can  be  low  and  wholesale  generators  (including  Generation)  use  their  retail  operations  to  hedge
generation output.

The  impact  of  sustained  low  market  prices  or  depressed  demand  and  over-supply  could  be  emphasized  given  Generation’s  concentration  of  base-load
electric generating capacity within primarily two geographic market regions, namely the Midwest and the Mid-Atlantic. These impacts could adversely affect
Generation’s  ability  to  fund  regulated  utility  growth  for  the  benefit  of  customers,  reduce  debt  and  provide  attractive  shareholder  returns.  In  addition,  such
conditions  may  no  longer  support  the  continued  operation  of  certain  generating  facilities,  which  could  adversely  affect  Generation's  financial  statements
primarily through accelerated depreciation and amortization expenses and one-time charges. See Note 7 — Early Plant Retirements of the Combined Notes
to Consolidated Financial Statements for additional information.

Cost of Fuel. Generation depends on nuclear fuel and fossil fuels to operate most of its generating facilities. The supply markets for nuclear fuel, natural
gas, and oil are subject to price fluctuations, availability restrictions, and counterparty default.

Market Designs. The wholesale markets vary from region to region with distinct rules, practices, and procedures. Changes in these market rules, problems
with  rule  implementation,  or  failure  of  any  of  these  markets  could  adversely  affect  Generation’s  business.  In  addition,  a  significant  decrease  in  market
participation could affect market liquidity and have a detrimental effect on market stability.

The Registrants are potentially affected by emerging technologies that could over time affect or transform the energy industry (All
Registrants).

Some of these technologies include, but are not limited to, further development or applications of technologies related to shale gas production, renewable
energy  technologies,  energy  efficiency,  distributed  generation,  and  energy  storage  devices.  Such  developments  could  affect  the  price  of  energy,  levels  of
customer-owned generation, customer expectations, and current business models and make portions of our electric system power supply and transmission
and/or  distribution  facilities  obsolete  prior  to  the  end  of  their  useful  lives.  Such  technologies  could  also  result  in  further  declines  in  commodity  prices  or
demand  for  delivered  energy.  Each  of  these  factors  could  affect  the  Registrants’  consolidated  financial  statements  through,  among  other  things,  reduced
operating revenues, increased operating and maintenance expenses, increased capital expenditures, and potential asset impairment charges or accelerated
depreciation and decommissioning expenses over shortened remaining asset useful lives.

Market performance and other factors could decrease the value of NDT funds and employee benefit plan assets and could increase
the related employee benefit plan obligations, which then could require significant additional funding (All Registrants).

Disruptions in the capital markets and their actual or perceived effects on particular businesses and the greater economy could adversely affect the value of
the investments held within Generation’s NDTs and Exelon’s employee benefit plan trusts. The Registrants have significant obligations in these areas and
Exelon and Generation hold substantial assets in these trusts to meet those obligations. The asset values are subject to market fluctuations and will yield
uncertain returns, which could fall below the Registrants’ projected return rates. A decline in the market value of the NDT fund investments could increase
Generation’s funding requirements to

32

Table of Contents

decommission its nuclear plants. A decline in the market value of the pension and OPEB plan assets would increase the funding requirements associated
with  Exelon’s  pension  and  OPEB  plan  obligations.  Additionally,  Exelon’s  pension  and  OPEB  plan  liabilities  are  sensitive  to  changes  in  interest  rates.  As
interest rates decrease, the liabilities increase, potentially increasing benefit costs and funding requirements. Changes in demographics, including increased
numbers of retirements or changes in life expectancy assumptions or changes to Social Security or Medicare eligibility requirements could also increase the
costs and funding requirements of the obligations related to the pension and OPEB plans. See Note 10 — Asset Retirement Obligations and Note 15 —
Retirement Benefits of the Combined Notes to Consolidated Financial Statements for additional information.

The Registrants could be negatively affected by unstable capital and credit markets and increased volatility in commodity markets
(All Registrants).

The  Registrants  rely  on  the  capital  markets,  particularly  for  publicly  offered  debt,  as  well  as  the  banking  and  commercial  paper  markets,  to  meet  their
financial commitments and short-term liquidity needs. Disruptions in the capital and credit markets in the United States or abroad could negatively affect the
Registrants’ ability to access the capital markets or draw on their respective bank revolving credit facilities. The banks may not be able to meet their funding
commitments to the Registrants if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a
short  period of time. The inability to access capital  markets  or  credit  facilities,  and  longer-term  disruptions  in  the  capital  and  credit  markets  as  a  result  of
uncertainty, changing or increased regulation, reduced alternatives, or failures of significant financial institutions could result in the deferral of discretionary
capital expenditures, Generation’s ability to hedge effectively its generation portfolio, changes to Generation’s hedging strategy in order to reduce collateral
posting  requirements,  or  a  reduction  in  dividend  payments  or  other  discretionary  uses  of  cash.  In  addition,  the  Registrants  have  exposure  to  worldwide
financial  markets,  including  Europe,  Canada,  and  Asia.  Disruptions  in  these  markets  could  reduce  or  restrict  the  Registrants’  ability  to  secure  sufficient
liquidity or secure liquidity at reasonable terms. As of December 31, 2020, approximately 23%, 19%, and 18% of the Registrants’ available credit facilities
were  with  European,  Canadian,  and  Asian  banks,  respectively.  See  Note  17  —  Debt  and  Credit  Agreements  of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information on the credit facilities.

The  strength  and  depth  of  competition  in  energy  markets  depend  heavily  on  active  participation  by  multiple  trading  parties,  which  could  be  negatively
affected by disruptions in the capital and credit markets and legislative and regulatory initiatives that could affect participants in commodities transactions.
Reduced capital and liquidity and failures of significant institutions that participate in the energy markets could diminish the liquidity and competitiveness of
energy markets that are important to the respective businesses of the Registrants. Perceived weaknesses in the competitive strength of the energy markets
could  lead  to  pressures  for  greater  regulation  of  those  markets  or  attempts  to  replace  market  structures  with  other  mechanisms  for  the  sale  of  power,
including the requirement of long-term contracts.

If any of the Registrants were to experience a downgrade in its credit ratings to below investment grade or otherwise fail to satisfy
the  credit  standards  in  its  agreements  with  its  counterparties,  it  would  be  required  to  provide  significant  amounts  of  collateral
under its agreements with counterparties and could experience higher borrowing costs (All Registrants).

Generation’s business is subject to credit quality standards that could require market participants to post collateral for their obligations. If Generation were to
be downgraded or lose its investment grade credit rating (based on its senior unsecured debt rating) or otherwise fail to satisfy the credit standards of trading
counterparties, it would be required under its hedging arrangements to provide collateral in the form of letters of credit or cash, which could have a material
adverse effect upon its liquidity. The amount of collateral required to be provided by Generation at any point in time depends on a variety of factors, including
(1) the notional amount of the applicable hedge, (2) the nature of counterparty and related agreements, and (3) changes in power or other commodity prices.
In addition, if Generation were downgraded, it could experience higher borrowing costs as a result of the downgrade. Changes in ratings methodologies by
the credit rating agencies could also have a negative impact on the ratings of Generation.

Generation has project-specific financing arrangements and must meet the requirements of various agreements relating to those financings. Failure to meet
those arrangements could give rise to a project-specific financing default which, if not cured or waived, could result in the specific project being required to
repay the associated

33

Table of Contents

debt  or  other  borrowings  earlier  than  otherwise  anticipated,  and  if  such  repayment  were  not  made,  the  lenders  or  security  holders  would  generally  have
broad  remedies,  including  rights  to  foreclose  against  the  project  assets  and  related  collateral  or  to  force  the  Exelon  subsidiaries  in  the  project-specific
financings to enter into bankruptcy proceedings. The impact of bankruptcy could result in the impairment of certain project assets.

The Utility Registrants' operating agreements with PJM and PECO's, BGE's, and DPL's natural gas procurement contracts contain collateral provisions that
are  affected  by  their  credit  rating  and  market  prices.  If  certain  wholesale  market  conditions  were  to  exist  and  the  Utility  Registrants  were  to  lose  their
investment grade credit ratings (based on their senior unsecured debt ratings), they would be required to provide collateral in the forms of letters of credit or
cash, which could have a material adverse effect upon their remaining sources of liquidity. PJM collateral posting requirements will generally increase as
market prices rise and decrease as market prices fall. Collateral posting requirements for PECO, BGE, and DPL, with respect to their natural gas supply
contracts, will generally increase as forward market prices fall and decrease as forward market prices rise. If the Utility Registrants were downgraded, they
could experience higher borrowing costs as a result of the downgrade. In addition, changes in ratings methodologies by the agencies could also have an
adverse negative impact on the ratings of the Utility Registrants.

The  Utility  Registrants  conduct  their  respective  businesses  and  operate  under  governance  models  and  other  arrangements  and  procedures  intended  to
assure that the Utility Registrants are treated as separate, independent companies, distinct from Exelon and other Exelon subsidiaries in order to isolate the
Utility  Registrants  from  Exelon  and  other  Exelon  subsidiaries  in  the  event  of  financial  difficulty  at  Exelon  or  another  Exelon  subsidiary.  These  measures
(commonly referred to as “ring-fencing”) could help avoid or limit a downgrade in the credit ratings of the Utility Registrants in the event of a reduction in the
credit rating of Exelon. Despite these ring-fencing measures, the credit ratings of the Utility Registrants could remain linked, to some degree, to the credit
ratings  of  Exelon.  Consequently,  a  reduction  in  the  credit  rating  of  Exelon  could  result  in  a  reduction  of  the  credit  rating  of  some  or  all  of  the  Utility
Registrants. A reduction in the credit rating of a Utility Registrant could have a material adverse effect on the Utility Registrant.

See  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS  —  Liquidity  and  Capital
Resources — Credit Matters — Market Conditions and Security Ratings for additional information regarding the potential impacts of credit downgrades on
the Registrants’ cash flows.

Generation’s risk management policies cannot fully eliminate the risk associated with its commodity trading activities (Exelon and
Generation).

Generation’s asset-based power position as well as its power marketing, fuel procurement, and other commodity trading activities expose Generation to risks
of commodity price movements. Generation buys and sells energy and other products and enters into financial contracts to manage risk and hedge various
positions  in  Generation’s  power  generation  portfolio.  Generation  is  exposed  to  volatility  in  financial  results  for  unhedged  positions  as  well  as  the  risk  of
ineffective hedges. Generation attempts to manage this exposure through enforcement of established risk limits and risk management procedures. These
risk limits and risk management procedures may not work as planned and cannot eliminate all risks associated with these activities. Even when its policies
and procedures are followed, and decisions are made based on projections and estimates of future performance, results of operations could be diminished if
the judgments and assumptions underlying those decisions prove to be incorrect. Factors, such as future prices and demand for power and other energy-
related commodities, become more difficult to predict and the calculations become less reliable the further into the future estimates are made. As a result,
Generation  cannot  predict  the  impact  that  its  commodity  trading  activities  and  risk  management  decisions  could  have  on  its  consolidated  financial
statements.

Financial performance and load requirements could be negatively affected if Generation is unable to effectively manage its power
portfolio (Exelon and Generation).

A significant portion of Generation’s power portfolio is used to provide power under procurement contracts with the Utility Registrants and other customers.
To the extent portions of the power portfolio are not needed for that purpose, Generation’s output is sold in the wholesale power markets. To the extent its
power portfolio is not sufficient to meet the requirements of its customers under the related agreements, Generation must purchase power in the wholesale
power  markets.  Generation’s  financial  results  could  be  negatively  affected  if  it  is  unable  to  cost-effectively  meet  the  load  requirements  of  its  customers,
manage its power portfolio or effectively address the changes in the wholesale power markets.

The  impacts  of  significant  economic  downturns  or  increases  in  customer  rates,  could  lead  to  decreased  volumes  delivered  and
increased expense for uncollectible customer balances (All Registrants).

The impacts of significant economic downturns on the Utility Registrants' customers, such as less demand for products and services provided by commercial
and industrial customers, and the related regulatory limitations on residential service terminations, could result in an increase in the number of uncollectible
customer  balances.  Further,  increases  in  customer  rates,  including  those  related  to  increases  in  purchased  power  and  natural  gas  prices,  could  result  in
declines in customer usage and lower revenues for the Utility Registrants that do not have decoupling mechanisms.

Generation's  customer-facing  energy  delivery  activities  face  similar  economic  downturn  risks,  such  as  lower  volumes  sold  and  increased  expense  for
uncollectible customer balances.

See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK for additional information of the Registrants’ credit risk.

The Registrants' results could be negatively affected by the impacts of COVID-19 (All Registrants).

COVID-19  is  an  evolving  situation  that  could  lead  to  extended  disruption  of  economic  activity  in  the  Registrants’  respective  markets.  COVID-19  could
negatively affect the Registrants’ ability to operate their respective generating and transmission and distribution assets, their ability to access capital markets,
and their results of operations. The Registrants cannot predict the extent of the impacts of COVID-19, which will depend on future developments and which
are  highly  uncertain.  See  Item  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS  -
Executive Overview for additional information.

The Registrants could be negatively affected by the impacts of weather (All Registrants).

Weather  conditions  directly  influence  the  demand  for  electricity  and  natural  gas  and  affect  the  price  of  energy  commodities.  Temperatures  above  normal
levels in the summer tend to increase summer cooling electricity demand and revenues, and temperatures below normal levels in the winter tend to increase
winter heating electricity and gas demand and revenues. Moderate temperatures adversely affect the usage of energy and resulting revenues at PECO, DPL
Delaware,  and  ACE.  Due  to  revenue  decoupling,  BGE,  Pepco,  and  DPL  Maryland  recognize  revenues  at  MDPSC  and  DCPSC-approved  levels  per
customer, regardless of what actual distribution volumes are for a billing period and are not affected by actual weather with the exception of major storms.
ComEd’s customer rates are adjusted to eliminate the favorable and unfavorable impacts of weather and customer usage patterns on distribution revenue.

Extreme  weather  conditions  or  damage  resulting  from  storms  could  stress  the  Utility  Registrants'  transmission  and  distribution  systems,  communication
systems, and technology, resulting in increased maintenance and capital costs and limiting each company’s ability to meet peak customer demand. First and
third quarter financial results, in particular, are substantially dependent on weather conditions, and could make period comparisons less relevant.

Generation’s  operations  are  also  affected  by  weather,  which  affects  demand  for  electricity  as  well  as  operating  conditions.  To  the  extent  that  weather  is
warmer  in  the  summer  or  colder  in  the  winter  than  assumed,  Generation  could  require  greater  resources  to  meet  its  contractual  commitments.  Extreme
weather conditions or storms could affect the availability of generation and its transmission, limiting Generation’s ability to source or send power to where it is
sold.  In  addition,  drought-like  conditions  limiting  water  usage  could  impact  Generation’s  ability  to  run  certain  generating  assets  at  full  capacity.  These
conditions, which cannot be accurately predicted, could cause Generation to seek additional capacity at a time when wholesale markets are tight or to seek
to sell excess capacity at a time when markets are weak.

Climate change projections suggest increases to summer temperature and humidity trends, as well as more erratic precipitation and storm patterns over the
long-term in the areas where Registrants have generation, transmission, and distribution assets. The frequency in which weather conditions emerge outside
the current expected climate norms could contribute to weather-related impacts discussed above.

Long-lived assets, goodwill, and other assets could become impaired (All Registrants).

Long-lived assets represent the single largest asset class on the Registrants’ statements of financial position. In addition, Exelon, ComEd, and PHI have
material goodwill balances.

The Registrants evaluate the recoverability of the carrying value of long-lived assets to be held and used whenever events or circumstances indicating a
potential  impairment  exist.  Factors  such  as,  but  not  limited  to,  the  business  climate,  including  current  and  future  energy  and  market  conditions,
environmental regulation, and the condition of assets are considered.

ComEd and PHI perform an assessment for possible impairment of their goodwill at least annually or more frequently if an event occurs or circumstances
change that would more likely than not reduce the fair value of the reporting units below their carrying amount. Regulatory actions or changes in significant
assumptions,  including  discount  and  growth  rates,  utility  sector  market  performance  and  transactions,  projected  operating  and  capital  cash  flows  for
ComEd’s,  Pepco’s,  DPL’s,  and  ACE’s  business,  and  the  fair  value  of  debt,  could  potentially  result  in  future  impairments  of  Exelon’s,  ComEd's,  and  PHI’s
goodwill.

An  impairment  would  require  the  Registrants  to  reduce  the  carrying  value  of  the  long-lived  asset  or  goodwill  to  fair  value  through  a  non-cash  charge  to
expense by the amount of the impairment. See ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS  —  Critical  Accounting  Policies  and  Estimates,  Note  8 — Property,  Plant,  and  Equipment,  Note  12  —  Asset  Impairments  and  Note  13 —
Intangible Assets of the Combined Notes to the Consolidated Financial Statements for additional information on long-lived asset impairments and goodwill
impairments.

The Registrants could incur substantial costs in the event of non-performance by third-parties under indemnification agreements,
or when the Registrants have guaranteed their performance. Generation is exposed to other credit risks in the power markets that
are beyond its control (All Registrants).

The Registrants have entered into various agreements with counterparties that require those counterparties to reimburse a Registrant and hold it harmless
against  specified  obligations  and  claims.  To  the  extent  that  any  of  these  counterparties  are  affected  by  deterioration  in  their  creditworthiness  or  the
agreements  are  otherwise  determined  to  be  unenforceable,  the  affected  Registrant  could  be  held  responsible  for  the  obligations.  Each  of  the  Utility
Registrants has transferred its former generation business to a third party and in each case the transferee has agreed to assume certain obligations and to
indemnify the applicable Utility Registrant for such obligations. In connection with the restructurings under which ComEd, PECO, and BGE transferred their
generating assets to Generation, Generation assumed certain of ComEd’s, PECO’s, and BGE's rights and obligations with respect to their former generation
businesses.  Further,  ComEd,  PECO,  and  BGE  have  entered  into  agreements  with  third  parties  under  which  the  third-party  agreed  to  indemnify  ComEd,
PECO,  or  BGE  for  certain  obligations  related  to  their  respective  former  generation  businesses  that  have  been  assumed  by  Generation  as  part  of  the
restructuring.  If  the  third-party,  Generation,  or  the  transferee  of  Pepco's,  DPL's,  or  ACE’s  generation  facilities  experienced  events  that  reduced  its
creditworthiness or the indemnity arrangement became unenforceable, the applicable Utility Registrant could be liable for any existing or future claims. In
addition, the Utility Registrants have residual liability under certain laws in connection with their former generation facilities.

The Registrants have issued indemnities to third parties regarding environmental or other matters in connection with purchases and sales of assets and they
could incur substantial costs to fulfill their obligations under these indemnities.

The Registrants have issued guarantees of the performance of third parties, which obligate the Registrants to perform in the event that the third parties do
not  perform.  In  the  event  of  non-performance  by  those  third  parties,  the  Registrants  could  incur  substantial  cost  to  fulfill  their  obligations  under  these
guarantees.

In the bilateral markets, Generation is exposed to the risk that counterparties that owe Generation money or are obligated to purchase energy or fuel from
Generation, will not perform under their obligations for operational or financial reasons. In the event the counterparties to these arrangements fail to perform,
Generation  could be forced to purchase or sell energy  or  fuel  in  the  wholesale  markets  at  less  favorable  prices  and  incur  additional  losses,  to  the  extent
amounts, if any, were already paid to the counterparties. In the spot markets, Generation is

36

Table of Contents

exposed  to  risk  as  a  result  of  default  sharing  mechanisms  that  exist  within  certain  markets,  primarily  RTOs  and  ISOs.  Generation  is  also  a  party  to
agreements  with  entities  in  the  energy  sector  that  have  experienced  rating  downgrades  or  other  financial  difficulties.  In  addition,  Generation’s  retail  sales
subject it to credit risk through competitive electricity and natural gas supply activities to serve commercial and industrial companies, governmental entities
and  residential  customers.  Retail  credit  risk  results  when  customers  default  on  their  contractual  obligations.  This  risk  represents  the  loss  that  could  be
incurred due to the nonpayment of a customer’s account balance, as well as the loss from the resale of energy previously committed to serve the customer.

Regulatory, Legislative, and Legal Factors

Federal  or  state  legislative  or  regulatory  actions  could  negatively  affect  the  scope  and  functioning  of  the  wholesale  markets
(Exelon and Generation).

Approximately  70%  of  Generation’s  generating  resources,  which  include  directly  owned  assets  and  capacity  obtained  through  long-term  contracts,  are
located in the area encompassed by PJM. Generation’s future results of operations are impacted by (1) FERC’s and PJM's support for policies that favor the
preservation of competitive wholesale power markets and recognize the value of zero-carbon electricity and resiliency and for states' energy objectives and
policies (2) the absence of material changes to market structures that would limit or otherwise negatively affect Exelon or Generation. Generation could also
be affected by state laws, regulations, or initiatives to subsidize existing or new generation.

FERC’s requirements for market-based rate authority could pose a risk that Generation may no longer satisfy FERC’s tests for market-based rates.

The Registrants’ are highly regulated and could be negatively affected by regulatory and legislative actions (All Registrants).

Substantially all aspects of the businesses of the Registrants are subject to comprehensive Federal or state regulation and legislation.

Generation’s consolidated financial statements are significantly affected by its sales and purchases of commodities at market-based rates, as opposed to
cost-based or other similarly regulated rates and Federal and state regulatory and legislative developments related to emissions, climate change, capacity
market  mitigation,  energy  price  information,  resilience,  fuel  diversity,  and  RPS.  Legislative  and  regulatory  efforts  in  Illinois,  New  York,  and  New  Jersey  to
preserve the environmental attributes and reliability benefits of zero-emission nuclear-powered generating facilities through ZEC programs are or could be
subject to legal and regulatory challenges and, if overturned, could result in the early retirement of certain of Generation’s nuclear plants. See Note 3 —
Regulatory Matters and Note 7 — Early Plant Retirements of the Combined Notes to Consolidated Financial Statements for additional information.

The  Utility  Registrants'  consolidated  financial  statements  are  heavily  dependent  on  the  ability  of  the  Utility  Registrants  to  recover  their  costs  for  the  retail
purchase and distribution of power and natural gas to their customers.

Fundamental  changes  in  regulations  or  other  adverse  legislative  actions  affecting  the  Registrants’  businesses  would  require  changes  in  their  business
planning models and operations. The Registrants cannot predict when or whether legislative and regulatory proposals could become law or what their effect
will be on the Registrants.

Changes  in  the  Utility  Registrants'  respective  terms  and  conditions  of  service,  including  their  respective  rates,  are  subject  to
regulatory approval proceedings and/or negotiated settlements that are at times contentious, lengthy, and subject to appeal, which
lead  to  uncertainty  as  to  the  ultimate  result  and  which  could  introduce  time  delays  in  effectuating  rate  changes  (Exelon  and  the
Utility Registrants).

The  Utility  Registrants  are  required  to  engage  in  regulatory  approval  proceedings  as  a  part  of  the  process  of  establishing  the  terms  and  rates  for  their
respective  services.  These  proceedings  typically  involve  multiple  parties,  including  governmental  bodies  and  officials,  consumer  advocacy  groups,  and
various consumers of

37

Table of Contents

energy, who have differing concerns but who have the common objective of limiting rate increases or even reducing rates. Decisions are subject to appeal,
potentially leading to additional uncertainty associated with the approval proceedings. The potential duration of such proceedings creates a risk that rates
ultimately approved by the applicable regulatory body may not be sufficient for a Utility Registrant to recover its costs by the time the rates become effective.
Established  rates  are  also  subject  to  subsequent  prudency  reviews  by  state  regulators,  whereby  various  portions  of  rates  could  be  adjusted,  subject  to
refund or disallowed, including recovery mechanisms for costs associated with the procurement of electricity or gas, credit losses, MGP remediation, smart
grid infrastructure, and energy efficiency and demand response programs. In certain instances, the Utility Registrants could agree to negotiated settlements
related to various rate matters, customer initiatives, or franchise agreements. These settlements are subject to regulatory approval. The ultimate outcome
and timing of regulatory rate proceedings have a significant effect on the ability of the Utility Registrants to recover their costs or earn an adequate return.
See Note 3 — Regulatory Matters of the Combined Notes to the Consolidated Financial Statements for additional information.

NRC  actions  could  negatively  affect  the  operations  and  profitability  of  Generation’s  nuclear  generating  fleet  (Exelon  and
Generation).

Regulatory risk. A change in the Atomic Energy Act or the applicable regulations or licenses could require a substantial increase in capital expenditures or
could result in increased operating or decommissioning costs. Events at nuclear plants owned by others, as well as those owned by Generation, could cause
the NRC to initiate such actions.

Spent nuclear fuel storage. The approval of a national repository for the storage of SNF and the timing of such a facility opening, will significantly affect the
costs associated with storage of SNF and the ultimate amounts received from the DOE to reimburse Generation for these costs.

Any regulatory action relating to the timing and availability of a repository for SNF could adversely affect Generation’s ability to fully decommission its nuclear
units. Generation cannot predict what, if any, fee may be established in the future for SNF disposal. See Note 19 — Commitments and Contingencies of the
Combined Notes to Consolidated Financial Statements for additional information on the SNF obligation.

The  Registrants  could  be  subject  to  higher  costs  and/or  penalties  related  to  mandatory  reliability  standards,  including  the  likely
exposure of the Utility Registrants to the results of PJM’s RTEP and NERC compliance requirements (All Registrants).

The  Registrants  as  users,  owners,  and  operators  of  the  bulk  power  transmission  system,  including  Generation  and  the  Utility  Registrants,  are  subject  to
mandatory reliability standards promulgated by NERC and enforced by FERC. PECO, BGE, and DPL, as operators of natural gas distribution systems, are
also subject to mandatory reliability standards of the U.S. Department of Transportation. The standards are based on the functions that need to be performed
to ensure the bulk power system operates reliably and are guided by reliability and market interface principles. Compliance with or changes in the reliability
standards  could  subject  the  Registrants  to  higher  operating  costs  and/or  increased  capital  expenditures.  In  addition,  the  ICC,  PAPUC,  MDPSC,  DCPSC,
DPSC, and NJBPU impose certain distribution reliability standards on the Utility Registrants. If the Registrants were found not to be in compliance with the
Federal and state mandatory reliability standards, they could be subject to remediation costs as well as sanctions, which could include substantial monetary
penalties.

The  Registrants  could  incur  substantial  costs  to  fulfill  their  obligations  related  to  environmental  and  other  matters  (All
Registrants).

The businesses that the Registrants operate are subject to extensive environmental regulation and legislation by local, state, and Federal authorities. These
laws and regulations affect the manner in which the Registrants conduct their operations and make capital expenditures including how they handle air and
water  emissions,  hazardous  and  solid  waste,  and  activities  affecting  surface  waters,  groundwater,  and  aquatic  and  other  species.  Violations  of  these
requirements could subject the Registrants to enforcement actions, capital expenditures to bring existing facilities into compliance, additional operating costs
for remediation and clean-up costs, civil penalties and exposure to third parties’ claims for alleged health or property damages, or operating restrictions to
achieve  compliance.  In  addition,  the  Registrants  are  subject  to  liability  under  these  laws  for  the  remediation  costs  for  environmental  contamination  of
property now or formerly owned by the Registrants and of property

38

Table of Contents

contaminated  by  hazardous  substances  they  generated  or  released.  Remediation  activities  associated  with  MGP  operations  conducted  by  predecessor
companies  are  one  component  of  such  costs.  Also,  the  Registrants  are  currently  involved  in  a  number  of  proceedings  relating  to  sites  where  hazardous
substances  have  been  deposited  and  could  be  subject  to  additional  proceedings  in  the  future.  See  ITEM  1.  BUSINESS  —  Environmental  Regulation  for
additional information.

The Registrants could be negatively affected by challenges to tax positions taken, tax law changes, and the inherent difficulty in
quantifying potential tax effects of business decisions. (All Registrants).

The Registrants are required to make judgments in order to estimate their obligations to taxing authorities. These tax obligations include income, real estate,
sales  and  use, and employment-related taxes and  ongoing  appeal  issues  related  to  these  tax matters.  These  judgments  include  reserves  established  for
potential adverse outcomes regarding tax positions that have been taken that could be subject to challenge by the tax authorities. See Note 1 — Significant
Accounting Policies and Note 14 — Income Taxes of the Combined Notes to Consolidated Financial Statements for additional information.

The Registrants could be negatively affected by federal and state RPS and/or energy conservation legislation, along with energy
conservation by customers (All Registrants).

Changes to current state legislation or the development of Federal legislation that requires the use of clean, renewable, and alternate fuel sources could
significantly impact Generation and the Utility Registrants, especially if timely cost recovery is not allowed for Utility Registrants. The impact could include
increased costs and increased rates for customers.

Federal and state legislation mandating the implementation of energy conservation programs that require the implementation of new technologies, such as
smart meters and smart grid, could increase capital expenditures and could significantly impact the Utility Registrants consolidated financial statements if
timely cost recovery is not allowed. Furthermore, regulated energy consumption reduction targets and declines in customer energy consumption resulting
from the implementation of new energy conservation technologies could lead to a decline in the revenues of the Registrants. See ITEM 1. BUSINESS —
Environmental Regulation — Renewable and Clean Energy Standards for additional information.

Generation’s affiliation with the Utility Registrants, together with the presence of a substantial percentage of Generation’s physical
asset base within the Utility Registrants' service territories, could increase Generation’s cost of doing business to the extent future
complaints  or  challenges  regarding  the  Utility  Registrants'  retail  rates  result  in  settlements  or  legislative  or  regulatory
requirements funded in part by Generation (Exelon and Generation).

Generation has significant generating resources within the service areas of the Utility Registrants and makes significant sales to each of them. Those facts
tend  to  cause  Generation  to  be  directly  affected  by  developments  in  those  markets.  Government  officials,  legislators,  and  advocacy  groups  are  aware  of
Generation’s affiliation with the Utility Registrants and its sales to each of them. In periods of rising utility rates, particularly when driven by increased costs of
energy production and supply, those officials and advocacy groups could question or challenge costs and transactions incurred by the Utility Registrants with
Generation,  irrespective  of  any  previous  regulatory  processes  or  approvals  underlying  those  transactions.  These  challenges  could  increase  the  time,
complexity,  and  cost  of  the  associated  regulatory  proceedings,  and  the  occurrence  of  such  challenges  could  subject  Generation  to  a  level  of  scrutiny  not
faced by other unaffiliated competitors in those markets. In addition, government officials and legislators could seek ways to force Generation to contribute to
efforts to mitigate potential or actual rate increases, through measures such as generation-based taxes.

The  Registrants  could  be  subject  to  adverse  publicity  and  reputational  risks,  which  make  them  vulnerable  to  negative  customer
perception and could lead to increased regulatory oversight or other consequences (All Registrants).

The Registrants could be the subject of public criticism. Adverse publicity of this nature could render public service commissions and other regulatory and
legislative  authorities  less  likely  to  view  energy  companies  such  as  Exelon  and  its  subsidiaries  in  a  favorable  light,  and  could  cause  Exelon  and  its
subsidiaries to be susceptible

39

Table of Contents

to  less  favorable  legislative  and  regulatory  outcomes,  as  well  as  increased  regulatory  oversight  and  more  stringent  legislative  or  regulatory  requirements
(e.g. disallowances of costs, lower ROEs).

Legal proceedings could result in a negative outcome, which the Registrants cannot predict (All Registrants).

The Registrants are involved in legal proceedings, claims, and litigation arising out of their business operations. The material ones are summarized in Note
19 — Commitments and Contingencies of the Combined Notes to Consolidated Financial Statements. Adverse outcomes in these proceedings could require
significant expenditures, result in lost revenue, or restrict existing business activities.

Exelon  and  ComEd  have  received  requests  for  information  related  to  an  SEC  investigation  into  their  lobbying  activities.  The
outcome  of  the  investigations  could  have  a  material  adverse  effect  on  their  reputation  and  consolidated  financial  statements
(Exelon and ComEd).

On October 22, 2019, the SEC notified Exelon and ComEd that it had opened an investigation into their lobbying activities in the state of Illinois. Exelon and
ComEd have cooperated fully, including by providing all information requested by the SEC, and intend to continue to cooperate fully and expeditiously with
the SEC. The outcome of the SEC’s investigation cannot be predicted and could subject Exelon and ComEd to civil penalties, sanctions, or other remedial
measures. Any of the foregoing, as well as the appearance of non-compliance with anti-corruption and anti-bribery laws, could have an adverse impact on
Exelon’s  and  ComEd’s  reputations  or  relationships  with  regulatory  and  legislative  authorities,  customers,  and  other  stakeholders,  as  well  as  their
consolidated financial statements. See Note 19 — Commitments and Contingencies of the Combined Notes to Consolidated Financial Statements.

If  ComEd  violates  its  Deferred  Prosecution  Agreement  announced  on  July  17,  2020,  it  could  have  an  adverse  effect  on  the
reputation and consolidated financial statements of Exelon and ComEd (Exelon and ComEd).

On July 17, 2020, ComEd entered into a Deferred Prosecution Agreement (DPA) with the U.S. Attorney’s Office for the Northern District of Illinois (USAO) to
resolve  the  USAO’s  investigation  into  Exelon’s  and  ComEd’s  lobbying  activities  in  the  State  of  Illinois.  Exelon  was  not  made  a  party  to  the  DPA  and  the
investigation  by  the  USAO  into  Exelon’s  activities  ended  with  no  charges  being  brought  against  Exelon.  Under  the  DPA,  the  USAO  filed  a  single  charge
alleging  that  ComEd  improperly  gave  and  offered  to  give  jobs,  vendor  subcontracts,  and  payments  associated  with  those  jobs  and  subcontracts  for  the
benefit  of  the  Speaker  of  the  Illinois  House  of  Representatives  and  the  Speaker’s  associates,  with  the  intent  to  influence  the  Speaker’s  action  regarding
legislation  affecting  ComEd’s  interests.  The  DPA  provides  that  the  USAO  will  defer  any  prosecution  of  such  charge  and  any  other  criminal  or  civil  case
against ComEd in connection with the matters identified therein for a three-year period subject to certain obligations of ComEd, including, but not limited to,
the following: (i) payment to the United States Treasury of $200 million; (ii) continued full cooperation with the government’s investigation; and (iii) ComEd’s
adoption  and  maintenance  of  remedial  measures  involving  compliance  and  reporting  undertakings  as  specified  in  the  DPA.  If  ComEd  is  found  to  have
breached the terms of the DPA, the USAO may elect to prosecute, or bring a civil action against, ComEd for conduct alleged in the DPA or known to the
government, which could result in fines or penalties and could have an adverse impact on Exelon’s and ComEd’s reputation or relationships with regulatory
and  legislative  authorities,  customers  and  other  stakeholders,  as  well  as  their  consolidated  financial  statements.  See  Note  19  —  Commitments  and
Contingencies of the Combined Notes to Consolidated Financial Statements.

Generation’s financial performance could be negatively affected by risks arising from its ownership and operation of hydroelectric
facilities (Exelon and Generation).

FERC  has  the  exclusive  authority  to  license  most  non-Federal  hydropower  projects  located  on  navigable  waterways,  Federal  lands  or  connected  to  the
interstate electric grid. Generation cannot predict whether it will receive all the regulatory approvals for the renewed licenses of its hydroelectric facilities. If
FERC does not issue new operating licenses for Generation’s hydroelectric facilities or a station cannot be operated through the end of its operating license,
Generation’s  results  of  operations  could  be  adversely  affected  by  increased  depreciation  rates  and  accelerated  future  decommissioning  costs,  since
depreciation rates and decommissioning cost estimates currently include assumptions that license renewal will be received. Generation could also lose

40

Table of Contents

revenue and incur increased fuel and purchased power expense to meet supply commitments. In addition, conditions could be imposed as part of the license
renewal process that could adversely affect operations, could require a substantial increase in capital expenditures, could result in increased operating costs
or could render the project uneconomic. Similar effects could result from a change in the Federal Power Act or the applicable regulations due to events at
hydroelectric facilities owned by others, as well as those owned by Generation.

Operational Factors

The Registrants are subject to risks associated with climate change (All Registrants).

The Registrants periodically perform analyses to better understand how climate change could affect their facilities and operations. The Registrants primarily
operate in the Midwest and East Coast of the United States, areas that historically have been prone to various types of severe weather events, such that the
Registrants have well-developed response and recovery programs based on these historical events. However, the Registrants’ physical facilities could be
placed  at  greater  risk  of  damage  should  changes  in  the  global  climate  impact  temperature  and  weather  patterns,  resulting  in  more  intense,  frequent  and
extreme  weather  events,  unprecedented  levels  of  precipitation,  sea  level  rise,  increased  surface  water  temperatures,  and/or  other  effects.  In  addition,
changes to the climate may impact levels and patterns of demand for energy and related services, which could affect Registrants’ operations. Over time, the
Registrants  may  need  to  make  additional  investments  to  protect  facilities  from  physical  climate-related  risks  and/or  adapt  to  changes  in  operational
requirements as a result of climate change.

The  Registrants  also  periodically  perform  analyses  of  potential  pathways  to  reduce  power  sector  and  economy-wide  GHG  emissions  to  mitigate  climate
change. To the extent additional GHG reduction regulation or legislation becomes effective at the Federal and/or state levels, the Registrants could incur
costs to further limit the GHG emissions from their operations or otherwise comply with applicable requirements. To the extent such additional regulation or
legislation does not become effective, the potential competitive advantage offered by Registrant’s low-carbon emission profile may be reduced. See ITEM 1.
BUSINESS — Climate Change Mitigation.

Generation’s  financial  performance  could  be  negatively  affected  by  matters  arising  from  its  ownership  and  operation  of  nuclear
facilities (Exelon and Generation).

Nuclear capacity factors. Capacity factors for nuclear generating units, significantly affect Generation’s results of operations. Lower capacity factors could
decrease  Generation’s  revenues  and  increase  operating  costs  by  requiring  Generation  to  produce  additional  energy  from  primarily  its  fossil  facilities  or
purchase  additional  energy  in  the  spot  or  forward  markets  in  order  to  satisfy  Generation’s  obligations  to  committed  third-party  sales,  including  the  Utility
Registrants. These sources generally have higher costs than Generation incurs to produce energy from its nuclear stations.

Nuclear refueling outages. In general, refueling outages are planned to occur once every 18 to 24 months. The total number of refueling outages, along
with their duration, could have a significant impact on Generation’s results of operations. When refueling outages last longer than anticipated or Generation
experiences  unplanned  outages,  capacity  factors  decrease,  and  Generation  faces  lower  margins  due  to  higher  energy  replacement  costs  and/or  lower
energy sales and higher operating and maintenance costs.

Nuclear fuel quality. The quality of nuclear fuel utilized by Generation could affect the efficiency and costs of Generation’s operations. Remediation actions
could  result  in  increased  costs  due  to  accelerated  fuel  amortization,  increased  outage  costs,  and/or  increased  costs  due  to  decreased  generation
capabilities.

Operational risk. Operations at any of Generation’s nuclear generation plants could degrade to the point where Generation must shut down the plant or
operate at less than full capacity. If this were to happen, identifying and correcting the causes could require significant time and expense. Generation could
choose to close a plant rather than incur the expense of restarting it or returning the plant to full capacity. In either event, Generation could lose revenue and
incur increased fuel and purchased power expense to meet supply commitments.

For  plants  operated  but  not  wholly  owned  by  Generation,  Generation  could  also  incur  liability  to  the  co-owners.  For  nuclear  plants  not  operated  and  not
wholly  owned  by  Generation,  from  which  Generation  receives  a  portion  of  the  plants’  output,  Generation’s  results  of  operations  are  dependent  on  the
operational performance of the operators and could be adversely affected by a significant event at those plants. Additionally, poor operating

41

Table of Contents

performance  at  nuclear  plants  not  owned  by  Generation  could  result  in  increased  regulation  and  reduced  public  support  for  nuclear-fueled  energy.  In
addition,  closure  of  generating  plants  owned  by  others,  or  extended  interruptions  of  generating  plants,  or  failure  of  transmission  lines,  could  affect
transmission systems that could adversely affect the sale and delivery of electricity in markets served by Generation.

Nuclear major incident risk and insurance. The  consequences  of  a  major  incident  could  be  severe  and  include  loss  of  life  and  property  damage.  Any
resulting  liability  from  a  nuclear  plant  major  incident  within  the  United  States,  owned  or  operated  by  Generation  or  owned  by  others,  could  exceed
Generation’s  resources,  including  insurance  coverage.  Generation  is  a  member  of  an  industry  mutual  insurance  company,  NEIL,  which  provides  property
and business interruption insurance for Generation’s nuclear operations. Uninsured losses and other expenses, to the extent not recovered from insurers or
the nuclear industry, could be borne by Generation. Additionally, an accident or other significant event at a nuclear plant within the United States or abroad,
whether owned by Generation or others, could result in increased regulation and reduced public support for nuclear-fueled energy.

As required by the Price-Anderson Act, Generation carries the maximum available amount of nuclear liability insurance, $450 million for each operating site.
Claims  exceeding  that  amount  are  covered  through  mandatory  participation  in  a  financial  protection  pool.  In  addition,  the  U.S.  Congress  could  impose
revenue-raising measures on the nuclear industry to pay claims exceeding the $13.8 billion limit for a single incident.

See  Note  19  —  Commitments  and  Contingencies  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  of  nuclear
insurance.

Decommissioning obligation and funding. NRC regulations require that licensees of nuclear generating facilities demonstrate reasonable assurance that
funds will be available in certain minimum amounts at the end of the life of the facility to decommission the facility.

Generation recognizes as a liability the present value of the estimated future costs to decommission its nuclear facilities. The estimated liability is based on
assumptions in the approach and timing of decommissioning the nuclear facilities, estimation of decommissioning costs, and Federal and state regulatory
requirements. The costs of such decommissioning may substantially exceed such liability, as facts, circumstances or our estimates may change, including
changes in the approach and timing of decommissioning activities, changes in decommissioning costs, changes in Federal or state regulatory requirements
on  the  decommissioning  of  such  facilities,  other  changes  in  our  estimates  or  Generation’s  ability  to  effectively  execute  on  its  planned  decommissioning
activities.

Generation makes contributions to certain trust funds of the former PECO units based on amounts being collected by PECO from its customers and remitted
to  Generation.  While  Generation,  through  PECO,  has  recourse  to  collect  additional  amounts  from  PECO  customers  (subject  to  certain  limitations  and
thresholds), it has no recourse to collect additional amounts from utility customers for any of its other nuclear units if there is a shortfall of funds necessary
for  decommissioning.  If  circumstances  changed  such  that  Generation  would  be  unable  to  continue  to  make  contributions  to  the  trust  funds  of  the  former
PECO  units  based  on  amounts  collected  from  PECO  customers,  or  if  Generation  no  longer  had  recourse  to  collect  additional  amounts  from  PECO
customers  if  there  was  a  shortfall  of  funds  for  decommissioning,  the  adequacy  of  the  trust  funds  related  to  the  former  PECO  units  could  be  negatively
affected.

Should the expected value of the NDT fund for any former ComEd unit fall below the amount of the expected decommissioning obligation for that unit, the
accounting  to  offset  decommissioning-related  activities  in  the  Consolidated  Statement  of  Operations  and  Comprehensive  Income  for  that  unit  would  be
discontinued, the decommissioning-related activities would be recognized in the Consolidated Statements of Operations and Comprehensive Income, and
the  adverse  impact to Exelon’s and Generation’s  financial  statements  could  be  material.  Any  changes  to  the  existing  PECO  regulatory  agreements  could
impact Exelon’s and Generation’s ability to offset decommissioning-related activities within the Consolidated Statement of Operations and Comprehensive
Income, and the impact to Exelon’s and Generation’s financial statements could be material.

Forecasting trust fund investment earnings and costs to decommission nuclear generating stations requires significant judgment, and actual results could
differ significantly from current estimates. If the investments held by Generation’s NDT funds are not sufficient to fund the decommissioning of Generation’s
nuclear units, Generation could be required to take steps, such as providing financial guarantees through letters of credit or parent

42

Table of Contents

company guarantees or making additional contributions to the trusts, which could be significant, to ensure that the trusts are adequately funded and that
current and future NRC minimum funding requirements are met.

See Note 10 — Asset Retirement Obligations of the Combined Notes to Consolidated Financial Statements for additional information.

The Utility Registrants' operating costs are affected by their ability to maintain the availability and reliability of their delivery and
operational systems (Exelon and the Utility Registrants).

Failures of the equipment or facilities used in the Utility Registrants' delivery systems could interrupt the electric transmission and electric and natural gas
delivery, which could result in a loss of revenues and an increase in maintenance and capital expenditures. Equipment or facilities failures can be due to a
number of factors, including natural causes such as weather or information systems failure. Specifically, if the implementation of AMI, smart grid, or other
technologies in the Utility Registrants' service territory fail to perform as intended or are not successfully integrated with billing and other information systems,
or  if  any  of  the  financial,  accounting,  or  other  data  processing  systems  fail  or  have  other  significant  shortcomings,  the  Utility  Registrants'  financial  results
could  be  negatively  impacted.  In  addition,  dependence  upon  automated  systems  could  further  increase  the  risk  that  operational  system  flaws  or  internal
and/or external tampering or manipulation of those systems will result in losses that are difficult to detect.

Regulated  utilities,  which  are  required  to  provide  service  to  all  customers  within  their  service  territory,  have  generally  been  afforded  liability  protections
against claims by customers relating to failure of service. Under Illinois law, however, ComEd could be required to pay damages to its customers in some
circumstances involving extended outages affecting large numbers of its customers, which could be material.

The Registrants are subject to physical security and cybersecurity risks (All Registrants).

The Registrants face physical security and cybersecurity risks. Threat sources continue to seek to exploit potential vulnerabilities in the electric and natural
gas utility industry associated with protection of sensitive and confidential information, grid infrastructure, and other energy infrastructures, and such attacks
and disruptions, both physical and cyber, are becoming increasingly sophisticated and dynamic. Continued implementation of advanced digital technologies
increases  the  potentially  unfavorable  impacts  of  such  attacks.  A  security  breach  of  the  physical  assets  or  information  systems  of  the  Registrants,  their
competitors,  vendors,  business  partners  and  interconnected  entities  in  RTOs  and  ISOs,  or  regulators  could  impact  the  operation  of  the  generation  fleet
and/or  reliability  of  the  transmission  and  distribution  system  or  result  in  the  theft  or  inappropriate  release  of  certain  types  of  information,  including  critical
infrastructure  information,  sensitive  customer,  vendor,  and  employee  data,  trading  or  other  confidential  data.  The  risk  of  these  system-related  events  and
security  breaches  occurring  continues  to  intensify,  and  while  the  Registrants  have  been,  and  will  likely  continue  to  be,  subjected  to  physical  and  cyber-
attacks, to date none has directly experienced a material breach or disruption to its network or information systems or our service operations. However, as
such attacks continue to increase in sophistication and frequency, the Registrants may be unable to prevent all such attacks in the future. If  a  significant
breach were to occur, the reputation of the Registrants could be negatively affected, customer confidence in the Registrants or others in the industry could
be diminished, or the Registrants could be subject to legal claims, loss of revenues, increased costs, or operations shutdown. Moreover, the amount and
scope  of  insurance  maintained  against  losses  resulting  from  any  such  events  or  security  breaches  may  not  be  sufficient  to  cover  losses  or  otherwise
adequately compensate for any disruptions to business that could result.

The Utility Registrants' deployment of smart meters throughout their service territories could increase the risk of damage from an intentional disruption of the
system by third parties.

In addition, new or updated security regulations or unforeseen threat sources could require changes in current measures taken by the Registrants or their
business operations and could adversely affect their consolidated financial statements.

The Registrants’ employees, contractors, customers, and the general public could be exposed to a risk of injury due to the nature
of the energy industry (All Registrants).

Employees  and  contractors  throughout  the  organization  work  in,  and  customers  and  the  general  public  could  be  exposed  to,  potentially  dangerous
environments near the Registrants’ operations. As a result, employees,

43

Table of Contents

contractors, customers, and the general public are at some risk for serious injury, including loss of life. These risks include nuclear accidents, dam failure,
gas explosions, pole strikes, and electric contact cases.

Natural  disasters,  war,  acts  and  threats  of  terrorism,  pandemic,  and  other  significant  events  could  negatively  impact  the
Registrants' results of operations, their ability to raise capital and their future growth (All Registrants).

Generation’s fleet of power plants and the Utility Registrants' distribution and transmission infrastructures could be affected by natural disasters and extreme
weather events, which could result in increased costs, including supply chain costs. An extreme weather event within the Registrants’ service areas can also
directly  affect  their  capital  assets,  causing  disruption  in  service  to  customers  due  to  downed  wires  and  poles  or  damage  to  other  operating  equipment.
Natural disasters and other significant events increase the risk to Generation that the NRC or other regulatory or legislative bodies could change the laws or
regulations  governing,  among  other  things,  operations,  maintenance,  licensed  lives,  decommissioning,  SNF  storage,  insurance,  emergency  planning,
security, and environmental and radiological matters. In addition, natural disasters could affect the availability of a secure and economical supply of water in
some locations, which is essential for Generation’s continued operation, particularly the cooling of generating units.

The impact that potential terrorist attacks could have on the industry and on Exelon is uncertain. The Registrants face a risk that their operations would be
direct  targets  or  indirect  casualties  of  an  act  of  terror.  Any  retaliatory  military  strikes  or  sustained  military  campaign  could  affect  their  operations  in
unpredictable  ways,  such  as  changes  in  insurance  markets  and  disruptions  of  fuel  supplies  and  markets,  particularly  oil.  Furthermore,  these  catastrophic
events could compromise the physical or cybersecurity of Exelon’s facilities, which could adversely affect Exelon’s ability to manage its business effectively.
Instability in the financial markets as a result of terrorism, war, natural disasters, pandemic, credit crises, recession, or other factors also could result in a
decline in energy consumption or interruption of fuel or the supply chain. In addition, the implementation of security guidelines and measures has resulted in
and is expected to continue to result in increased costs.

The Registrants could be significantly affected by the outbreak of a pandemic. Exelon has plans in place to respond to a pandemic. However, depending on
the severity of a pandemic and the resulting impacts to workforce and other resource availability, the ability to operate Exelon's generating and transmission
and distribution assets could be affected.

In addition, Exelon maintains a level of insurance coverage consistent with industry practices against property, casualty and cybersecurity losses subject to
unforeseen occurrences or catastrophic events that could damage or destroy assets or interrupt operations. However, there can be no assurance that the
amount of insurance will be adequate to address such property and casualty losses.

The  Registrants’  businesses  are  capital  intensive,  and  their  assets  could  require  significant  expenditures  to  maintain  and  are
subject to operational failure, which could result in potential liability (All Registrants).

The  Registrants’  businesses  are  capital  intensive  and  require  significant  investments  by  Generation  in  electric  generating  facilities  and  by  the  Utility
Registrants  in  transmission  and  distribution  infrastructure  projects.  Equipment,  even  if  maintained  in  accordance  with  good  utility  practices,  is  subject  to
operational failure, including events that are beyond the Registrants’ control, and could require significant expenditures to operate efficiently. The Registrants
consolidated financial statements could be negatively affected if they were unable to effectively manage their capital projects or raise the necessary capital.
See  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS  —  Liquidity  and  Capital
Resources for additional information regarding the Registrants’ potential future capital expenditures.

The  Utility  Registrants'  respective  ability  to  deliver  electricity,  their  operating  costs,  and  their  capital  expenditures  could  be
negatively  impacted  by  transmission  congestion  and  failures  of  neighboring  transmission  systems  (Exelon  and  the  Utility
Registrants).

Demand for electricity within the Utility Registrants' service areas could stress available transmission capacity requiring alternative routing or curtailment of
electricity  usage.  Also,  insufficient  availability  of  electric  supply  to  meet  customer  demand  could  jeopardize  the  Utility  Registrants'  ability  to  comply  with
reliability standards and strain customer and regulatory agency relationships. As with all utilities, potential concerns over transmission

44

Table of Contents

capacity or generation facility retirements could result in PJM or FERC requiring the Utility Registrants to upgrade or expand their respective transmission
systems through additional capital expenditures.

PJM’s systems and operations are designed to ensure the reliable operation of the transmission grid and prevent the operations of one utility from having an
adverse  impact  on  the  operations  of  the  other  utilities.  However,  service  interruptions  at  other  utilities  may  cause  interruptions  in  the  Utility  Registrants’
service areas.

The  Registrants  consolidated  financial  statements  could  be  negatively  affected  if  they  fail  to  attract  and  retain  an  appropriately
qualified workforce (All Registrants).

Certain  events,  such  as  an  employee  strike,  loss  of  contract  resources  due  to  a  major  event,  and  an  aging  workforce  without  appropriate  replacements,
could lead to operating challenges and increased costs for the Registrants. The challenges include lack of resources, loss of knowledge and a lengthy time
period associated with skill development. In this case, costs, including costs for contractors to replace employees, productivity costs, and safety costs, could
arise.  The  Registrants  are  particularly  affected  due  to  the  specialized  knowledge  required  of  the  technical  and  support  employees  for  their  generation,
transmission, and distribution operations.

The  Registrants  could  make  acquisitions  or  investments  in  new  business  initiatives  and  new  markets,  which  may  not  be
successful or achieve the intended financial results (All Registrants).

Generation could continue to pursue growth in its existing businesses and markets and further diversification across the competitive energy value chain. This
could  include  investment  opportunities  in  renewables,  development  of  natural  gas  generation,  nuclear  advisory  or  operating  services  for  third  parties,
distributed generation, potential expansion of the existing wholesale gas businesses, and entry into LNG. Such initiatives could involve significant risks and
uncertainties,  including  distraction  of  management  from  current  operations,  inadequate  return  on  capital,  and  unidentified  issues  not  discovered  during
diligence performed prior to launching an initiative or entering a market. Additionally, it is possible that FERC, state public utility commissions or others could
impose certain other restrictions on such transactions. All of these factors could result in higher costs or lower revenues than expected, resulting in lower
than planned returns on investment.

The Utility Registrants face risks associated with their regulatory-mandated initiatives, such as smart grids and utility of the future. These risks include, but
are not limited to, cost recovery, regulatory concerns, cybersecurity, and obsolescence of technology. Such initiatives may not be successful.

The Registrants may not realize or achieve the anticipated cost savings through the cost management efforts (All Registrants).

The  Registrants’  future  financial  performance  and  level  of  profitability  is  dependent,  in  part,  on  various  cost  reduction  initiatives.  The  Registrants  may
encounter challenges in executing these cost reduction initiatives and not achieve the intended cost savings.

Risks Related to the Planned Separation (Exelon and Generation)

The planned separation is contingent upon regulatory approvals and satisfaction of other conditions and may not be completed in
accordance  with  the  expected  plans  or  anticipated  timeline,  or  at  all,  which  could  negatively  affect  Exelon’s  and  Generation’s
consolidated financial statements.

Exelon is targeting to complete the separation in the first quarter of 2022, subject to final approval by Exelon’s Board of Directors, a Form 10 registration
statement being declared effective by the SEC, regulatory approvals, and satisfaction of other conditions. The planned separation is subject to approval by
the FERC, NRC and NYPSC. There can be no assurance that any separation transaction will ultimately occur or, if one does occur, of its terms or timing. If
the planned separation is not completed or is delayed, Exelon’s and Generation’s consolidated financial statements may be materially adversely affected,
and the market price of Exelon’s common stock may be affected.

45

Table of Contents

The  plan  to  separate  into  two  publicly  traded  companies  will  involve  significant  time  and  expense,  which  could  disrupt  or
adversely affect our business.

The planned separation is complex in nature, and unanticipated developments or changes, including challenges in executing the separation, could delay or
prevent the completion of the proposed separation, or cause the separation to occur on terms or conditions that are different or less favorable than expected.
Additionally, Exelon’s Board of Directors, in its sole and absolute discretion, may decide not to proceed with the separation at any time prior to the distribution
date. The process of completing the proposed separation has been and is expected to continue to be time-consuming and involves significant costs and
expenses.

The  planned  separation  may  not  achieve  some  or  all  of  the  anticipated  benefits  and  each  separate  company  following  the
separation may underperform relative to Exelon’s expectations.

By separating the Utility Registrants and Generation, Exelon is creating two publicly traded companies with the resources necessary to best serve customers
and sustain long-term investment and operating excellence. The separate companies are expected to create value by having the strategic flexibility to focus
on their unique customer, market and community priorities. However, the planned separation may not provide such results on the scope or scale that Exelon
anticipates, and Exelon and Generation may not realize the anticipated benefits of the planned separation. Failure to do so could have a material adverse
effect on the financial statements of each separate company and their respective common stock price.

Following the planned separation, the companies anticipate to maintain investment grade credit ratings. Ratings are based upon assessments of multiple
factors, including a company’s credit metrics as well as industry and macroeconomic changes and trends. If a rating agency were to downgrade the rating
below investment grade, the separate companies’ borrowing costs would increase and their funding sources could decrease, which could have a material
adverse effect on the financial statements of the affected company.

The  common  stock  of  the  separately  publicly  traded  companies  following  the  separation  may  collectively  trade  at  a  value  less  than  the  price  at  which
Exelon’s common stock might have traded had the separation not occurred.

There could be significant liability if the planned spin-off is determined to be a taxable transaction.

Under  the  separation  plan,  Exelon  shareholders  will  retain  their  current  shares  of  Exelon  stock  and  receive  a  pro-rata  distribution  of  shares  of  the  new
company’s stock in a transaction that is expected to be tax-free to Exelon and its shareholders under Sections 355 and 368 of the IRC. Exelon will seek a
private letter ruling from the IRS regarding the tax-free nature of the transaction. Exelon will also seek from its tax advisors an opinion with respect to certain
U.S. federal income tax consequences of the spin-off. If the planned spin-off ultimately is determined to be taxable, the spin-off could be treated as a taxable
dividend to Exelon’s shareholders for U.S. federal income tax purposes, and Exelon’s shareholders could incur significant U.S. federal income tax liabilities.
In addition, Exelon would recognize a taxable gain to the extent that the fair market value of the new company’s stock exceeds its tax basis in such stock on
the date of the planned separation. Exelon will enter into a Tax Matters Agreement with the new company to address how post-separation issues will be
managed between the companies, as well as which company is responsible for taxes imposed as a result of the planned separation, if any.

See Note 26 — Subsequent Events of the Combined Notes to Consolidated Financial Statements for additional information on the planned separation.

__________
(a) All nuclear stations are boiling water reactors except Braidwood, Byron, Calvert Cliffs, Ginna, and Salem, which are pressurized water reactors.
(b) 100%, unless otherwise indicated.
(c) Base-load  units  are  plants  that  normally  operate  to  take  all  or  part  of  the  minimum  continuous  load  of  a  system  and,  consequently,  produce  electricity  at  an  essentially
constant rate. Intermittent units are plants with output controlled by the natural variability of the energy resource rather than dispatched based on system requirements.
Intermediate units are plants that normally operate to take load of a system during the daytime higher load hours and, consequently, produce electricity by cycling on and
off daily. Peaking units consist of lower-efficiency, quick response steam units, gas turbines and diesels normally used during the maximum load periods.

(d) For nuclear stations, capacity reflects the annual mean rating. Fossil stations and wind and solar facilities reflect a summer rating.
(e) Generation has announced it will permanently cease generation operations at Byron and Dresden nuclear facilities in 2021 and Mystic Unit 8 and 9 in 2024. See Note 7 —

Early Plant Retirements of the Combined Notes to the Consolidated Financial Statements for additional information.

(f) Net generation capacity is stated at proportionate ownership share.
(g) Reflects the prior sale of 49% of EGRP to a third party. See Note 23 — Variable Interest Entities of the Combined Notes to Consolidated Financial Statements for additional

information.

(h) On December 8, 2020, Generation entered into an agreement with an affiliate of Brookfield Renewable, for the sale of a significant portion of Generation's solar business.
The transaction is expected to be completed in the first half of 2021. See Note 2 — Mergers, Acquisitions, and Dispositions of the Combined Notes to the Consolidated
Financial Statements for additional information.

(i) Generation has deactivated the site and is evaluating for potential return of service or retirement beyond 2021.
(j) Reflects  Generation’s  interest  in  CENG,  a  joint  venture  with  EDF.  See  ITEM  1.  —  BUSINESS  —  Exelon  Generation  Company,  LLC  —  Nuclear  Facilities  for  additional

information.

(k) EGRP owns 100% of the Class A membership interests and a tax equity investor owns 100% of the Class B membership interests of the entity that owns the Bluestem

generating assets.

(l) Generation directly owns a 50% interest in the Albany Green Energy station and an additional 49% through the consolidation of a Variable Interest Entity.
(m) Generation has plans to retire and cease plant operations in 2021.

The  net  generation  capability  available  for  operation  at  any  time  may  be  less  due  to  regulatory  restrictions,  transmission  congestion,  fuel  restrictions,
efficiency of cooling facilities, level of water supplies, or generating units being temporarily out of service for inspection, maintenance, refueling, repairs, or
modifications required by regulatory authorities.

Generation maintains property insurance against loss or damage to its principal plants and properties by fire or other perils, subject to certain exceptions. For
additional  information  regarding  nuclear  insurance  of  generating  facilities,  see  ITEM  1.  BUSINESS  —  Exelon  Generation  Company,  LLC.  For  its  insured
losses,  Generation  is  self-insured  to  the  extent  that  any  losses  are  within  the  policy  deductible  or  exceed  the  amount  of  insurance  maintained.  Any  such
losses could have a material adverse effect in Generation’s consolidated financial condition or results of operations.

The Utility Registrants

The  Utility  Registrants'  electric  substations  and  a  portion  of  their  transmission  rights  are  located  on  property  that  they  own. A  significant  portion  of  their
electric transmission and distribution facilities are located above or underneath highways, streets, other public places, or property that others own. The Utility
Registrants believe that they have satisfactory rights to use those places or property in the form of permits, grants, easements, licenses, and franchise rights;
however, they have not necessarily undertaken to examine the underlying title to the land upon which the rights rest.

Transmission and Distribution

The Utility Registrants’ high voltage electric transmission lines owned and in service at December 31, 2020 were as follows:

earnings.  A  significant  loss  recorded  at  Generation,  ComEd,  PECO,  BGE,  PHI,  Pepco,  DPL,  or  ACE  may  limit  the  dividends  that  these  companies  can
distribute to Exelon.

ComEd has agreed in connection with a financing arranged through ComEd Financing III that ComEd will not declare dividends on any shares of its capital
stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinated debt securities issued to ComEd Financing III;
(2) it defaults on its

55

Table of Contents

guarantee of the payment of distributions on the preferred trust securities of ComEd Financing III; or (3) an event of default occurs under the Indenture under
which the subordinated debt securities are issued. No such event has occurred.

PECO has agreed in connection with financings arranged through PEC L.P. and PECO Trust IV that PECO will not declare dividends on any shares of its
capital stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinated debentures which were issued to PEC L.P.
or  PECO  Trust  IV;  (2)  it  defaults  on  its  guarantee  of  the  payment  of  distributions  on  the  Series  D  Preferred  Securities  of  PEC  L.P.  or  the  preferred  trust
securities of PECO Trust IV; or (3) an event of default occurs under the Indenture under which the subordinated debentures are issued. No such event has
occurred.

BGE is subject to restrictions established by the MDPSC that prohibit BGE from paying a dividend on its common shares if (a) after the dividend payment,
BGE’s equity ratio would be below 48% as calculated pursuant to the MDPSC’s ratemaking precedents or (b) BGE’s senior unsecured credit rating is rated
by two of the three major credit rating agencies below investment grade. No such event has occurred.

Pepco  is  subject  to  certain  dividend  restrictions  established  by  settlements  approved  in  Maryland  and  the  District  of  Columbia.  Pepco  is  prohibited  from
paying a dividend on its common shares if (a) after the dividend payment, Pepco's equity ratio would be below 48% as equity levels are calculated under the
ratemaking precedents of the MDPSC and DCPSC or (b) Pepco’s senior unsecured credit rating is rated by one of the three major credit rating agencies
below investment grade. No such event has occurred.

DPL is subject to certain dividend restrictions established by settlements approved in Delaware and Maryland. DPL is prohibited from paying a dividend on
its common shares if (a) after the dividend payment, DPL's equity ratio would be below 48% as equity levels are calculated under the ratemaking precedents
of the DPSC and MDPSC or (b) DPL’s senior unsecured credit rating is rated by one of the three major credit rating agencies below investment grade. No
such event has occurred.

ACE is subject to certain dividend restrictions established by settlements approved in New Jersey. ACE is prohibited from paying a dividend on its common
shares  if  (a)  after  the  dividend  payment,  ACE's  equity  ratio  would  be  below  48%  as  equity  levels  are  calculated  under  the  ratemaking  precedents  of  the
NJBPU or (b) ACE's senior unsecured credit rating is rated by one of the three major credit rating agencies below investment grade. ACE is also subject to a
dividend  restriction  which  requires  ACE  to  obtain  the  prior  approval  of  the  NJBPU  before  dividends  can  be  paid  if  its  equity  as  a  percent  of  its  total
capitalization, excluding securitization debt, falls below 30%. No such events have occurred.

Exelon’s  Board  of  Directors  approved  an  updated  dividend  policy  for  2021.  The  2021  quarterly  dividend  will  remain  the  same  as  the  2020  dividend  of
$0.3825 per share.

At December 31, 2020, Exelon had retained earnings of $16,735 million, including Generation’s undistributed earnings of $2,805 million, ComEd’s retained
earnings  of  $1,456  million  consisting  of  retained  earnings  appropriated  for  future  dividends  of  $3,095  million,  partially  offset  by  $1,639  million  of
unappropriated accumulated deficits, PECO’s retained earnings of $1,519 million, BGE’s retained earnings of $1,879 million, and PHI's undistributed losses
of $68 million.

Item 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Exelon

Executive Overview

Exelon is a utility services holding company engaged in the generation, delivery, and marketing of energy through Generation and the energy distribution and
transmission businesses through ComEd, PECO, BGE, Pepco, DPL, and ACE.

Exelon  has  eleven  reportable  segments  consisting  of  Generation’s  five  reportable  segments  (Mid-Atlantic,  Midwest,  New  York,  ERCOT,  and  Other  Power
Regions), ComEd, PECO, BGE, Pepco, DPL, and ACE. See Note 1 — Significant Accounting Policies and Note 5 — Segment Information of the Combined
Notes to Consolidated Financial Statements for additional information regarding Exelon's principal subsidiaries and reportable segments.

Exelon’s consolidated financial information includes the results of its eight separate operating subsidiary registrants, Generation, ComEd, PECO, BGE, PHI,
Pepco,  DPL,  and  ACE,  which,  along  with  Exelon,  are  collectively  referred  to  as  the  Registrants.  The  following  combined  Management’s  Discussion  and
Analysis  of  Financial  Condition  and  Results  of  Operations  summarizes  results  for  the  year  ended  December  31,  2020  compared  to  the  year  ended
December 31, 2019, and is separately filed by Exelon, Generation, ComEd, PECO, BGE, PHI, Pepco, DPL, and ACE. However, none of the Registrants
makes any representation as to information related solely to any of the other Registrants. For discussion of the year ended December 31, 2019 compared to
the year ended December 31, 2018, refer to ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS in the 2019 Form 10-K, which was filed with the SEC on February 11, 2020.

COVID-19. The Registrants have taken steps to mitigate the potential risks posed by the global outbreak (pandemic) of COVID-19. The Registrants provide
a  critical  service  to  our  customers  which  means  that  it  is  paramount  that  we  keep  our  employees  who  operate  our  businesses  safe  and  minimize
unnecessary risk of exposure to the virus. The Registrants have taken extra precautions for our employees who work in the field and for employees who
continue  to  work  in  our  facilities.  The  Registrants  have  implemented  work  from  home  policies  where  appropriate,  and  imposed  travel  limitations  on  their
employees. In addition, the Registrants have updated existing business continuity plans in the context of this pandemic.

The Registrants continue to implement strong physical and cyber-security measures to ensure that our systems remain functional in order to both serve our
operational needs with a remote workforce and keep them running to ensure uninterrupted service to our customers.

There  were  no  changes  in  internal  control  over  financial  reporting  in  2020  as  a  result  of  COVID-19  that  materially  affected,  or  are  reasonably  likely  to
materially affect, any of the Registrants’ internal control over financial reporting. See ITEM 9A. CONTROLS AND PROCEDURES for additional information.

Unfavorable economic conditions due to COVID-19 have impacted the demand for electricity and natural gas at Generation and the Utility Registrants, which
has resulted in a decrease in operating revenues.

As  a  result  of  COVID-19,  Generation  temporarily  suspended  interruption  of  service  for  all  retail  residential  customers  for  non-payment  and  temporarily
ceased  new  late  payment  fees  for  all  retail  customers  from  March  to  May  of  2020.  Starting  in  March  of  2020,  the  Utility  Registrants  also  temporarily
suspended customer disconnections for non-payment and temporarily ceased new late payment fees for all customers and restored service to customers
upon  request  who  were  disconnected  in  the  last  twelve  months.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial
Statements  for  additional  information  on  such  measures  at  the  Utility  Registrants.  At  Generation,  such  measures  resulted  in  an  increase  in  credit  loss
expense. ComEd and ACE recorded regulatory assets for the incremental credit loss expense based on existing mechanisms. BGE, PECO, Pepco, and DPL
also recorded regulatory assets for substantially all the incremental credit loss expense incurred in 2020. See Note 3 — Regulatory Matters of the Combined
Notes to Consolidated Financial Statements for additional information.

58

Table of Contents

Generation  and  the  Utility  Registrants  have  also  incurred  direct  costs  related  to  COVID-19  consisting  primarily  of  costs  to  acquire  personal  protective
equipment, costs for cleaning supplies and services, and costs to hire healthcare professionals to monitor the health of their employees. At Generation and
PECO, such costs are recorded as Operating and maintenance expense and are excluded from Adjusted (non-GAAP) Operating Earnings. At ComEd, BGE,
Pepco, DPL, and ACE, such costs are primarily recorded as regulatory assets. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated
Financial Statements for additional information.

The estimated impact to Generation’s and the Utility Registrants’ Net income is approximately $170 million and $75 million for the year ended December 31,
2020, respectively.

To  offset  the  unfavorable  impacts  from  COVID-19,  the  Registrants  identified  approximately  $250  million  in  cost  savings  across  Generation  and  the  Utility
Registrants in 2020. The cost savings achieved in 2020 were higher than originally anticipated.

The Registrants rely on the capital markets for publicly offered debt as well as the commercial paper markets to meet their financial commitments and short-
term liquidity needs. As a result of the disruptions in the commercial paper markets in March of 2020, Generation borrowed $1.5 billion on its revolving credit
facility to refinance commercial paper, which Generation repaid on April 3, 2020. Generation also entered into two short-term loan agreements in March of
2020 for an aggregate of $500 million. On April 8, 2020, Generation received approximately $500 million in cash after entering into an accounts receivable
financing arrangement. On April 24, 2020, Exelon Corporate entered into a credit agreement establishing a $550 million 364-day revolving credit facility to be
used as an additional source of short-term liquidity. In addition, the Registrants issued long-term debt of $5.3 billion and were able to successfully complete
their  planned  long-term  debt  issuances  in  2020.  See  Liquidity  and  Capital  Resources,  Note  17  —  Debt  and  Credit  Agreements,  and  Note  6  —  Accounts
Receivable of the Combined Notes to Consolidated Financial Statements for additional information.

The Registrants assessed long-lived assets, goodwill, and investments for recoverability and there were no material impairment charges recorded in 2020 as
a result of COVID-19. See Note 12 — Asset Impairments for additional information related to other impairment assessments in the third quarter of 2020.
Certain  assumptions  are  highly  sensitive  to  changes.  Changes  in  significant  assumptions  could  potentially  result  in  future  impairments,  which  could  be
material.

This is an evolving situation that could lead to extended disruption of economic activity in our markets. The Registrants will continue to monitor developments
affecting their workforce, customers, and suppliers and will take additional precautions that they determine to be necessary in order to mitigate the impacts.
The extent to which COVID-19 may impact the Registrants’ ability to operate their generating and transmission and distribution assets, the ability to access
capital markets, and results of operations, including demand for electricity and natural gas, will depend on the spread and proliferation of COVID-19 around
the world and future developments, which are highly uncertain and cannot be predicted at this time.

(a) Primarily includes eliminating and consolidating adjustments, Exelon’s corporate operations, shared service entities, and other financing and investing activities.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019. Net income attributable to common shareholders decreased by $973
million and diluted earnings per average common share decreased to $2.01 in 2020 from $3.01 in 2019 primarily due to:

•

•

•

•

•

•

•

•

•

•

•

One-time charges and accelerated depreciation and amortization associated with Generation's decisions in the third quarter of 2020 to early
retire Byron and Dresden nuclear facilities in 2021 and Mystic Units 8 and 9 in 2024, partially offset by the absence of accelerated depreciation
and amortization due to the early retirement of TMI in September 2019;

Impairment of the New England asset group;

Payments that ComEd made under the Deferred Prosecution Agreement. See Note 19 — Commitments and Contingencies of the Combined
Notes to Consolidated Financial Statements for additional information;

Lower capacity revenue;

Reduction in load due to COVID-19 at Generation;

Lower realized energy prices;

Higher nuclear outage days;

Impact of Generation's annual update to the nuclear ARO for Non-Regulatory Agreement Units;

Lower net unrealized and realized gains on NDT funds;

COVID-19 direct costs;

Lower electric distribution earnings from lower allowed ROE due to a decrease in treasury rates, partially offset by higher rate base at ComEd;

•

•

•

Higher storm costs related to the June 2020 and August 2020 storms at PECO, net of tax repairs, and related to the August 2020 storm at
DPL;

Unfavorable weather conditions at PECO, DPL Delaware, and ACE; and

A net increase in depreciation and amortization expense due to ongoing capital expenditures at PECO, BGE, Pepco, DPL, and ACE, partially
offset at Generation due to the impact of extending the operating license at Peach Bottom.

The decreases were partially offset by;

•

•

•

•

•

•

Higher mark-to-market gains;

Unrealized gains resulting from equity investments without readily determinable fair values that became publicly traded entities in the fourth
quarter and were fair valued based on quoted market prices of the stocks as of December 31, 2020;

Lower operating and maintenance expense at Generation primarily due to previous cost management programs, lower contracting costs, and
lower travel costs, partially offset by lower NEIL insurance distributions;

Lower nuclear fuel costs;

A tax benefit related to a settlement in the first quarter of 2020, partially offset by the absence of a tax benefit related to certain research and
development activities recorded in the fourth quarter of 2019 at Generation; and

Regulatory rate increases at BGE, DPL, and ACE.

Adjusted (non-GAAP) Operating Earnings. In addition  to net income, Exelon evaluates its operating  performance  using  the  measure  of  Adjusted  (non-
GAAP) operating earnings because management believes it represents earnings directly related to the ongoing operations of the business. Adjusted (non-
GAAP)  operating  earnings  exclude  certain  costs,  expenses,  gains  and  losses,  and  other  specified  items.  This  information  is  intended  to  enhance  an
investor’s overall understanding of year-to-year operating results and provide an indication of Exelon’s baseline operating performance excluding items that
are  considered  by  management  to  be  not  directly  related  to  the  ongoing  operations  of  the  business.  In  addition,  this  information  is  among  the  primary
indicators  management  uses  as  a  basis  for  evaluating  performance,  allocating  resources,  setting  incentive  compensation  targets,  and  planning  and
forecasting  of  future  periods.  Adjusted  (non-GAAP)  operating  earnings  is  not  a  presentation  defined  under  GAAP  and  may  not  be  comparable  to  other
companies’ presentations or deemed more useful than the GAAP information provided elsewhere in this report.

__________
Note:
Amounts may not sum due to rounding.
Unless otherwise noted, the income tax impact of each reconciling item between GAAP Net Income and Adjusted (non-GAAP) Operating Earnings is based on the marginal
statutory federal and state income tax rates for each Registrant, taking into account whether the income or expense item is taxable or deductible, respectively, in whole or in
part. For all items except the unrealized gains and losses related to NDT funds, the marginal statutory income tax rates for 2020 and 2019 ranged from 26.0% to 29.0%. Under
IRS regulations, NDT fund investment returns are taxed at different rates for investments if they are in qualified or non-qualified funds. The effective tax rates for the unrealized
gains and losses related to NDT funds were 52.1% and 47.3% for the years ended December 31, 2020 and 2019, respectively.

(a) Reflects the impact of net unrealized gains and losses on Generation’s NDT fund investments for Non-Regulatory and Regulatory Agreement Units. The impacts of the

Regulatory Agreement Units, including the associated income taxes, are contractually eliminated, resulting in no earnings impact.
In 2020, reflects an impairment at ComEd in the second quarter of 2020 related to the acquisition of transmission assets and an impairment of the New England asset
group  in  the  third  quarter  of  2020.  In  2019,  primarily  reflects  the  impairment  of  equity  method  investments  in  certain  distributed  energy  companies.  The  impact  of  such
impairment net of noncontrolling interest is $0.02.
In 2020, primarily reflects one-time charges and accelerated depreciation and amortization associated with Generation's decisions in the third quarter of 2020 to early retire
Byron and Dresden nuclear facilities in 2021 and Mystic Units 8 and 9 in 2024. In 2019, primarily reflects accelerated depreciation and amortization expenses associated
with the early retirement of the TMI nuclear facility and certain fossil sites and the loss on the sale of Oyster Creek to Holtec, partially offset by net realized gains related to
Oyster Creek's NDT fund investments, a net benefit associated with remeasurements of the TMI ARO, and a gain on the sale of certain wind assets.

nuclear ARO update for CENG units, partially offset by the impairment of certain equity investments in distributed energy companies.

Significant 2020 Transactions and Developments

Planned Separation

On  February  21,  2021,  Exelon’s  Board  of  Directors  approved  a  plan  to  separate  the  Utility  Registrants  and  Generation,  creating  two  publicly  traded
companies with the resources necessary to best serve customers and sustain long-term investment and operating excellence. The separation gives each
company  the  financial  and  strategic  independence  to  focus  on  its  specific  customer  needs,  while  executing  its  core  business  strategy.  See  Note  26  —
Subsequent Events of the Combined Notes to Consolidated Financial Statements for additional information.

Impacts of February 2021 Weather Events and Texas-based Generating Assets Outages

Beginning on February 15, 2021, Generation’s Texas-based generating assets within the ERCOT market, specifically Colorado Bend II, Wolf Hollow II, and
Handley,  experienced  periodic  outages  as  a  result  of  historically  severe  cold  weather  conditions.  In  addition,  those  weather  conditions  drove  increased
demand for service, limited the availability of natural gas to fuel power plants, and dramatically increased wholesale power and gas prices.

Exelon  and  Generation  estimate  the  impact  to  their  Net  income  for  the  first  quarter  of  2021  arising  from  these  market  and  weather  conditions  to  be
approximately $560 million to $710 million. The estimated impact includes favorable results in certain regions within Generation’s wholesale gas business.
The ultimate impact to Exelon’s and Generation’s consolidated financial statements may be affected by a number of factors, including final settlement data,
the impacts of customer and counterparty credit losses, any state sponsored solutions to address the financial challenges caused by the event, and litigation
and  contract  disputes  which  may  result.  Exelon  expects  to  offset  between  $410  million  and  $490  million  of  this  impact  primarily  at  Generation  through  a
combination of enhanced revenue opportunities, deferral of selected non-essential maintenance, and primarily one-time cost savings.

See Note 26 — Subsequent Events of the Combined Notes to Consolidated Financial Statements for additional information.

Agreement for Sale of Generation’s Solar Business

On December 8, 2020, Generation entered into an agreement with an affiliate of Brookfield Renewable, for the sale of a significant portion of Generation’s
solar  business,  including  360  megawatts  of  generation  in  operation  or  under  construction  across  more  than  600  sites  across  the  United  States,  for  a
purchase  price  of  $810  million.  Completion  of  the  transaction  is  expected  to  occur  in  the  first  half  of  2021.  Generation  will  retain  certain  solar  assets  not
included  in  this  agreement,  primarily  Antelope  Valley.  See  Note  2  —  Mergers,  Acquisitions,  and  Dispositions  of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information.

In August 2020, Generation announced that it intends to retire the Byron Generating Station in September 2021, Dresden Generating Station in November
2021,  and  Mystic  Units  8  and  9  at  the  expiration  of  the  cost  of  service  commitment  in  May  2024.  As  a  result,  in  the  third  quarter  of  2020,  Exelon  and
Generation recognized a $500 million impairment of its New England asset group and one-time non-cash charges for Byron, Dresden, and Mystic related to
materials  and  supplies  inventory  reserve  adjustments,  employee-related  costs,  and  construction  work-in-progress  impairments,  among  other  items.  In
addition, there will be ongoing annual financial impacts stemming from shortening the expected economic useful lives of these facilities, primarily related to
accelerated  depreciation  of  plant  assets  (including  any  ARC)  and  accelerated  amortization  of  nuclear  fuel.  Such  ongoing  charges  are  excluded  from
Adjusted (non-GAAP) Operating Earnings.

The  following  table  summarizes  the  incremental  expense  recorded  for  the  year  ended  December  31,  2020  and  the  estimated  amounts  of  incremental
expense expected to be incurred through the retirement dates.

(a) Actual results may differ based on incremental future capital additions, actual units of production for nuclear fuel amortization, future revised ARO assumptions, etc.
(b) Reflects incremental accelerated depreciation of plant assets, including any ARC.
(c) Reflects primarily the net impacts associated with the remeasurement of the ARO for Dresden. See Note 10 – Asset Retirement Obligations of the Combined Notes to

Consolidated Financial Statements for additional information.

(d) Reflects contractual offset for ARO accretion, ARC depreciation, and net impacts associated with the remeasurement of the ARO for Byron and Dresden. Based on the

regulatory agreement with the ICC, decommissioning-related activities are offset within Exelon's and Generation's Consolidated Statements of Operations and
Comprehensive Income as long as the net cumulative decommissioning-related activities result in a regulatory liability at ComEd. Recognition of a regulatory asset for
nuclear decommissioning-related activities at ComEd is not permissible. The offset results in an equal adjustment to the noncurrent payables to ComEd at Generation and
an adjustment to the regulatory liabilities at ComEd. See Note 10 – Asset Retirement Obligations of the Combined Notes to Consolidated Financial Statements for
additional information.

Deferred Prosecution Agreement

On July 17, 2020, ComEd entered into a Deferred Prosecution Agreement (DPA) with the U.S. Attorney’s Office for the Northern District of Illinois (USAO) to
resolve the USAO’s investigation into ComEd’s lobbying activities in the State of Illinois. Under the DPA, the USAO filed a single charge alleging that ComEd
improperly gave and offered to give jobs, vendor subcontracts, and payments associated with those jobs and subcontracts for the benefit of the Speaker of
the Illinois House of Representatives and the Speaker’s associates, with the intent to influence the Speaker’s action regarding legislation affecting ComEd’s
interests. The DPA provides that the USAO will defer any prosecution of such charge and any other criminal or civil case against ComEd in connection with
the matters identified therein for a three-year period subject to certain obligations of ComEd, including payment to the United States Treasury of $200 million,
with $100 million payable within thirty days of the filing of the DPA with the United States District Court for the Northern District of Illinois and an additional
$100 million within ninety days of such filing date. The payments will not be recovered in rates or charged to customers, and ComEd will not seek or accept
reimbursement or indemnification from any source other than Exelon. See Note 19 — Commitments and Contingencies for additional information.

Sales of Customer Accounts Receivable

On April 8, 2020, NER, a bankruptcy remote, special purpose entity, which is wholly owned by Generation, entered into an accounts receivable financing
facility  with  a  number  of  financial  institutions  and  a  commercial  paper  conduit  to  sell  certain  customer  accounts  receivables.  Generation  received
approximately $500 million of cash in accordance with the initial sale of approximately $1.2 billion receivables. See Note 6 — Accounts Receivable of the
Combined Notes to Consolidated Financial Statements for additional information.

Exelon’s Strategy and Outlook

On  February  21,  2021,  Exelon’s  Board  of  Directors  approved  a  plan  to  separate  the  Utility  Registrants  and  Generation,  creating  two  publicly  traded
companies with the resources necessary to best serve customers and sustain long-term investment and operating excellence. The separation gives each
company  the  financial  and  strategic  independence  to  focus  on  its  specific  customer  needs,  while  executing  its  core  business  strategy.  See  Note  26  —
Subsequent Events of the Combined Notes to Consolidated Financial Statements for additional information.

In 2021, the businesses remain focused on maintaining industry leading operational excellence, meeting or exceeding their financial commitments, ensuring
timely  recovery  on  investments  to  enable  customer  benefits,  supporting  enactment  of  clean  energy  policies,  and  continued  commitment  to  corporate
responsibility.

Exelon’s utility strategy is to improve reliability and operations and enhance the customer experience, while ensuring ratemaking mechanisms provide the
utilities  fair  financial  returns.  The  Utility  Registrants  only  invest  in  rate  base  where  it  provides  a  benefit  to  customers  and  the  community  by  improving
reliability and the service experience or otherwise meeting customer needs. The Utility Registrants make these investments at the lowest

66

Table of Contents

reasonable cost to customers. Exelon seeks to leverage its scale and expertise across the utilities platform through enhanced standardization and sharing of
resources and best practices to achieve improved operational and financial results. Additionally, the Utility Registrants anticipate making significant future
investments  in  smart  grid  technology,  transmission  projects,  gas  infrastructure,  and  electric  system  improvement  projects,  providing  greater  reliability  and
improved service for our customers and a stable return for the company.

Generation’s  competitive  businesses  create  value  for  customers  by  providing  innovative  energy  solutions  and  reliable,  clean,  and  affordable  energy.
Generation’s electricity generation strategy is to pursue opportunities that provide stable revenues and match supply to customers. Generation leverages its
energy generation portfolio to deliver energy to both wholesale and retail customers. Generation’s customer-facing activities foster development and delivery
of  other  innovative  energy-related  products  and  services  for  its  customers.  Generation  operates  in  well-developed  energy  markets  and  employs  an
integrated hedging strategy to manage commodity price volatility. Its generation fleet, including its nuclear plants which consistently operate at high capacity
factors, also provide geographic and supply source diversity. These factors help Generation mitigate the current challenging conditions in competitive energy
markets.

Various market, financial, regulatory, legislative and operational factors could affect the Registrants' success in pursuing their strategies. Exelon continues to
assess  infrastructure,  operational,  commercial,  policy,  and  legal  solutions  to  these  issues.  One  key  issue  is  ensuring  the  ability  to  properly  value  nuclear
generation assets in the market, solutions to which Exelon is actively pursuing in a variety of jurisdictions and venues. See ITEM 1A. RISK FACTORS for
additional information regarding market and financial factors.

Growth Opportunities

Management continually evaluates growth opportunities aligned with Exelon’s businesses, assets and markets, leveraging Exelon’s expertise in those areas
and offering sustainable returns.

Regulated Energy Businesses. The  Utility  Registrants  anticipate  investing  approximately  $27  billion  over  the  next  four  years  in  electric  and  natural  gas
infrastructure  improvements  and  modernization  projects,  including  smart  grid  technology,  storm  hardening,  advanced  reliability  technologies,  and
transmission projects, which is projected to result in an increase to current rate base of approximately $15 billion by the end of 2024. The Utility Registrants
invest  in  rate  base  where  beneficial  to  customers  and  the  community  by  increasing  reliability  and  the  service  experience  or  otherwise  meeting  customer
needs. These investments are made at the lowest reasonable cost to customers.

Competitive  Energy  Businesses.  Generation  continually  assesses  the  optimal  structure  and  composition  of  its  generation  assets  as  well  as  explores
wholesale and retail opportunities within the power and gas sectors. Generation’s strategy is to ensure appropriate valuation of its generation assets, in part
through  public  policy  efforts,  identify  and  capitalize  on  opportunities  that  match  supply  to  customers  as  a  means  to  provide  stable  earnings,  and  identify
emerging technologies where strategic investments provide the option for significant future growth or influence in market development.

Other Key Business Drivers and Management Strategies

Utility Rates and Rate Proceedings

The Utility Registrants file rate cases with their regulatory commissions seeking increases or decreases to their electric transmission and distribution, and
gas  distribution  rates  to  recover  their  costs  and  earn  a  fair  return  on  their  investments.  The  outcomes  of  these  regulatory  proceedings  impact  the  Utility
Registrants’  current  and  future  results  of  operations,  cash  flows,  and  financial  positions.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to
Consolidated Financial Statements for additional information on these regulatory proceedings.

Power Markets

Price of Fuels

The use of new technologies to recover natural gas from shale deposits is increasing natural gas supply and reserves, which places downward pressure on
natural gas prices and, therefore, on wholesale and retail power prices, which results in a reduction in Exelon’s revenues. Forward natural gas prices have
declined significantly

67

Table of Contents

over the last several years; in part reflecting an increase in supply due to strong natural gas production (due to shale gas development).

Section 232 Uranium Petition

On  January  16,  2018,  two  Canadian-owned  uranium  mining  companies  with  operations  in  the  U.S.  jointly  submitted  a  petition  to  the  U.S.  Department  of
Commerce  ("DOC")  seeking  relief  under  Section  232  of  the  Trade  Expansion  Act  of  1962  from  imports  of  uranium  products,  alleging  that  these  imports
threaten national security.

The United States Nuclear Fuel Working Group ("Working Group") report was made public on April 23, 2020. The Working Group report states that nuclear
power is intrinsically tied to national security, and promises that the U.S. government will take bold actions to strengthen all parts of the nuclear fuel industry
in the U.S. It recommends the Agreement Suspending the Antidumping Investigation on Uranium from the Russian Federation (the “Russian Suspension
Agreement”  or  "RSA")  be  extended  and  to  consider  reducing  the  amount  of  Russian  imports  of  nuclear  fuel.  The  Russian  Suspension  Agreement  is  the
historical resolution of a 1991 DOC investigation that found that the Russians had been selling or “dumping” cheap uranium products into the U.S. The RSA
has been amended several times in the intervening years to allow Russia to supply limited amounts of uranium products into the U.S. It was set to expire at
the end of 2020, but was amended on October 5, 2020 to extend for another 20 years.

The  Working  Group  report  should  be  viewed  as  policy  recommendations  that  may  be  implemented  by  executive  agencies,  congress,  and  or  regulatory
bodies. Exelon and Generation cannot currently predict the outcome of all of the policy changes recommended by the Working Group.

Complaint at FERC Seeking to Alter Capacity Market Default Offer Caps

On February 21, 2019, PJM's Independent Market Monitor (IMM) filed a complaint alleging that the number of performance assessment intervals used to
calculate  the  default  offer  cap  for  bids  to  supply  capacity  in  PJM  is  too  high,  resulting  in  an  overstated  default  offer  cap  that  obviates  the  need  for  most
sellers to seek unit-specific approval of their offers. The IMM claims that this allows for the exercise of market power. The IMM asks FERC to require PJM to
reduce the number of performance assessment intervals used to calculate the opportunity costs of a capacity supplier assuming a capacity obligation. This
would, in turn, lower the default offer cap and allow the IMM to review more offers on a unit-specific basis. It is too early to predict the final outcome of this
proceeding or its potential financial impact, if any, on Exelon or Generation.

Energy Demand

Load growth at the Utility Registrants is driven by recovery from COVID-19 impacts. ComEd and PECO are projecting modest growth in load of 2.5% and
1.8%, respectively, in 2021 as compared to reduced load in 2020. BGE, Pepco, DPL, and ACE are projecting slower growth as prolonged COVID-19 impacts
decrease load by (2.0)%, (0.8)%, (0.9)%, and (2.4)%, respectively, in 2021 compared to 2020.

Retail Competition

Generation’s retail operations compete for customers in a competitive environment, which affect the margins that Generation can earn and the volumes that
it is able to serve. Forward natural gas and power prices are expected to remain low and thus we expect retail competitors to stay aggressive in their pursuit
of market share, and that wholesale generators (including Generation) will continue to use their retail operations to hedge generation output.

Hedging Strategy

Exelon’s  policy  to  hedge  commodity  risk  on  a  ratable  basis  over  three-year  periods  is  intended  to  reduce  the  financial  impact  of  market  price  volatility.
Generation  is  exposed  to  commodity  price  risk  associated  with  the  unhedged  portion  of  its  electricity  portfolio.  Generation  enters  into  non-derivative  and
derivative  contracts,  including  financially-settled  swaps,  futures  contracts  and  swap  options,  and  physical  options  and  physical  forward  contracts,  all  with
credit-approved counterparties, to hedge this anticipated exposure. As of December 31, 2020, the percentage of expected generation hedged for the Mid-
Atlantic, Midwest, New York, and ERCOT reportable segments is 94%-97% for 2021. Generation has been and will continue to be proactive in using hedging
strategies to mitigate commodity price risk.

68

Table of Contents

Generation  procures  natural  gas  through  long-term  and  short-term  contracts  and  spot-market  purchases.  Nuclear  fuel  assemblies  are  obtained
predominantly through long-term uranium concentrate supply contracts, contracted conversion services, contracted enrichment services, or a combination
thereof,  and  contracted  fuel  fabrication  services.  The  supply  markets  for  uranium  concentrates  and  certain  nuclear  fuel  services  are  subject  to  price
fluctuations and availability restrictions. Approximately 60% of Generation’s uranium concentrate requirements from 2021 through 2025 are supplied by three
suppliers. In the event of non-performance by these or other suppliers, Generation believes that replacement uranium concentrate can be obtained, although
at prices that may be unfavorable when compared to the prices under the current supply agreements. Non-performance by these counterparties could have
a material adverse impact on Exelon’s and Generation’s consolidated financial statements.

See  Note  16  —  Derivative  Financial  Instruments  of  the  Combined  Notes  to  Consolidated  Financial  Statements  and  ITEM  7A.  QUANTITATIVE  AND
QUALITATIVE DISCLOSURES ABOUT MARKET RISK for additional information.

The Utility Registrants mitigate commodity price risk through regulatory mechanisms that allow them to recover procurement costs from retail customers.

Other Legislative and Regulatory Developments

Illinois Clean Energy Progress Act

On March 14, 2019, the Clean Energy Progress Act was introduced in the Illinois General Assembly to preserve Illinois’ clean energy choices arising from
FEJA and empower the IPA to conduct capacity procurements outside of PJM’s base residual auction process, while utilizing the FRR provisions in PJM's
tariffs  which  are  still  subject  to  penalties  and  other  obligations  under  the  PJM  tariffs.  The  most  significant  provisions  of  the  proposed  legislation  are  as
follows:  (1)  it  allows  the  IPA  to  procure  capacity  directly  from  clean  energy  resources  that  have  previously  sold  ZECs  or  RECs,  including  certain  of
Generation’s  nuclear  plants  in  Illinois,  or  from  new  clean  energy  resources,  (2)  it  establishes  a  goal  of  achieving  100%  carbon-free  power  in  the  ComEd
service territory by 2032, and (3) it implements reforms to enhance consumer protections in the state’s competitive retail electricity and natural gas markets,
including Generation’s retail customers. Energy legislation has also been proposed by other stakeholders in 2019 and 2020, including renewable resource
developers, environmental advocates, and coal-fueled generators. Lawmakers focused their efforts on understanding all of the various legislative proposals
with the goal of developing a single comprehensive energy package for ultimate consideration by the General Assembly and Governor Pritzker. Due to the
COVID-19 pandemic, the legislative calendar during 2020 was severely curtailed stalling progress on comprehensive energy legislation. The fall 2020 veto
session  was  cancelled.  The  next  opportunity  for  the  General  Assembly  to  consider  development  of  comprehensive  energy  legislation  appears  to  come
during the 2021 spring legislative session. Exelon and Generation will work with legislators and stakeholders and cannot predict the outcome or the potential
financial impact, if any, on Exelon or Generation.

Nuclear Powers Act of 2019

On April 12, 2019, the Nuclear Powers America Act of 2019 was introduced to the United States Congress, which expands the current investment tax credit
to existing nuclear power plants. The proposed legislation would provide a credit equal to 30% of continued capital investment in certain nuclear energy-
related expenditures, including capital expenses and nuclear fuel, starting from tax years 2019 through 2023. Thereafter, the credit rate would be reduced to
26% in 2024, 22% in 2025, and 10% in 2026 and beyond. To qualify for the credit, the plant must be currently operational and must have applied for an
operating  license  renewal  before  2026.    Exelon  and  Generation  are  working  with  legislators  and  stakeholders  and  cannot  predict  the  outcome  or  the
potential financial impact, if any, on Exelon or Generation.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with GAAP requires that management apply accounting policies and make estimates and assumptions
that  affect  results  of  operations  and  the  amounts  of  assets  and  liabilities  reported  in  the  financial  statements.  Management  believes  that  the  accounting
policies described below require significant judgment in their application, or incorporate estimates and assumptions that are inherently

69

Table of Contents

uncertain and that may change in subsequent periods. Additional information of the application of these accounting policies can be found in the Combined
Notes to Consolidated Financial Statements.

Nuclear Decommissioning Asset Retirement Obligations (Exelon and Generation)

Generation’s  ARO  associated  with  decommissioning  its  nuclear  units  was  $11.9  billion  at  December  31,  2020.  The  authoritative  guidance  requires  that
Generation estimate its obligation for the future decommissioning of its nuclear generating plants. To estimate that liability, Generation uses an internally-
developed, probability-weighted, discounted cash flow model which, on a unit-by-unit basis, considers multiple decommissioning outcome scenarios.

As a result of recent nuclear plant retirements in the industry, nuclear operators and third-party service providers are obtaining more information about costs
associated with decommissioning activities. At the same time, regulators are gaining more information about decommissioning activities which could result in
changes to existing decommissioning requirements. In addition, as more nuclear plants are retired, it is possible that technological advances will be identified
that  could  create  efficiencies  and  lead  to  a  reduction  in  decommissioning  costs.  The  availability  of  NDT  funds  could  impact  the  timing  of  the
decommissioning activities. Additionally, certain factors such as changes in regulatory requirements during plant operations or the profitability of a nuclear
plant  could  impact  the  timing  of  plant  retirements.  These  factors  could  result  in  material  changes  to  Generation’s  current  estimates  as  more  information
becomes available and could change the timing of plant retirements and the probability assigned to the decommissioning outcome scenarios.

The nuclear decommissioning obligation is adjusted on a regular basis due to the passage of time and revisions to the key assumptions for the expected
timing  and/or  estimated  amounts  of  the  future  undiscounted  cash  flows  required  to  decommission  the  nuclear  plants,  based  upon  the  following
methodologies and significant estimates and assumptions:

Decommissioning Cost Studies. Generation uses unit-by-unit decommissioning cost studies to provide a marketplace assessment of the expected costs
(in current year dollars) and timing of decommissioning activities, which are validated by comparison to current decommissioning projects within the industry
and other estimates. Decommissioning cost studies are updated, on a rotational basis, for each of Generation’s nuclear units at least every five years, unless
circumstances warrant more frequent updates. As part of the annual cost study update process, Generation evaluates newly assumed costs or substantive
changes in previously assumed costs to determine if the cost estimate impacts are sufficiently material to warrant application of the updated estimates to the
AROs across the nuclear fleet outside of the normal five-year rotating cost study update cycle.

Cost Escalation Factors. Generation uses cost escalation factors to escalate the decommissioning costs from the decommissioning cost studies discussed
above  through  the  assumed  decommissioning  period  for  each  of  the  units.  Cost  escalation  studies,  updated  on  an  annual  basis,  are  used  to  determine
escalation factors, and are based on inflation indices for labor, equipment and materials, energy, LLRW disposal, and other costs. All of the nuclear AROs
are adjusted each year for the updated cost escalation factors.

Probabilistic  Cash  Flow  Models.  Generation’s  probabilistic  cash  flow  models  include  the  assignment  of  probabilities  to  various  scenarios  for
decommissioning  cost  levels,  decommissioning  approaches,  and  timing  of  plant  shutdown  on  a  unit-by-unit  basis.  Probabilities  assigned  to  cost  levels
include  an  assessment  of  the  likelihood  of  costs  20%  higher  (high-cost  scenario)  or  15%  lower  (low-cost  scenario)  than  the  base  cost  scenario.  The
assumed decommissioning scenarios include the following three alternatives: (1) DECON which assumes decommissioning activities begin shortly after the
cessation  of  operation,  (2)  Shortened  SAFSTOR  generally  has  a  30-year  delay  prior  to  onset  of  decommissioning  activities,  and  (3)  SAFSTOR  which
assumes  the  nuclear  facility  is  placed  and  maintained  in  such  condition  that  the  nuclear  facility  can  be  safely  stored  and  subsequently  decontaminated
generally within 60 years after cessation of operations. In each decommissioning scenario, spent fuel is transferred to dry cask storage as soon as possible
until DOE acceptance for disposal.

The actual decommissioning approach selected once a nuclear facility is shutdown will be determined by Generation at the time of shutdown and may be
influenced by multiple factors including the funding status of the NDT fund at the time of shutdown.

The  assumed  plant  shutdown  timing  scenarios  include  the  following  four  alternatives:  (1)  the  probability  of  operating  through  the  original  40-year  nuclear
license term, (2) the probability of operating through an extended

70

Table of Contents

60-year nuclear license term (regardless of whether such 20-year license extension has been received for each unit), (3) the probability of a second, 20-year
license renewal for some nuclear units, and (4) the probability of early plant retirement for certain sites due to changing market conditions and regulatory
environments. As power market and regulatory environment developments occur, Generation evaluates and incorporates, as necessary, the impacts of such
developments into its nuclear ARO assumptions and estimates.

Generation’s probabilistic cash flow models also include an assessment of the timing of DOE acceptance of SNF for disposal. Generation currently assumes
DOE will begin accepting SNF in 2035. The SNF acceptance date assumption is based on management’s estimates of the amount of time required for DOE
to select a site location and develop the necessary infrastructure for long-term SNF storage. For additional information regarding the estimated date when
DOE will begin accepting SNF, see Note 19 — Commitments and Contingencies of the Combined Notes to Consolidated Financial Statements.

Discount  Rates.  The  probability-weighted  estimated  future  cash  flows  for  the  various  assumed  scenarios  are  discounted  using  credit-adjusted,  risk-free
rates  (CARFR)  applicable  to  the  various  businesses  in  which  each  of  the  nuclear  units  originally  operated.  Generation  initially  recognizes  an  ARO  at  fair
value and subsequently adjusts it for changes to estimated costs, timing of future cash flows and modifications to decommissioning assumptions. The ARO
is not required or permitted to be re-measured for changes in the CARFR that occur in isolation. Increases in the ARO as a result of upward revisions in
estimated  undiscounted  cash  flows  are  considered  new  obligations  and  are  measured  using  a  current  CARFR  as  the  increase  creates  a  new  cost  layer
within the ARO. Any decrease in the estimated undiscounted future cash flows relating to the ARO are treated as a modification of an existing ARO cost
layer and, therefore, is measured using the average historical CARFR rates used in creating the initial ARO cost layers. If Generation’s future nominal cash
flows  associated  with  the  ARO  were  to  be  discounted  at  current  prevailing  CARFR,  the  obligation  would  increase  from  approximately  $11.9  billion  to
approximately $15.0 billion.

Goodwill (Exelon, ComEd, and PHI)

As of December 31, 2020, Exelon’s $6.7 billion carrying amount of goodwill consists primarily of $2.6 billion at ComEd and $4 billion at PHI. These entities
are  required  to  perform  an  assessment  for  possible  impairment  of  their  goodwill  at  least  annually  or  more  frequently  if  an  event  occurs  or  circumstances
change that would more likely than not reduce the fair value of the reporting units below their carrying amount. A reporting unit is an operating segment or
one level below an operating segment (known as a component) and is the level at which goodwill is assessed for impairment. ComEd has a single operating
segment and reporting unit. PHI’s operating segments and reporting units are Pepco, DPL, and ACE. See Note 5 — Segment Information of the Combined
Notes to Consolidated Financial Statements for additional information. Exelon's and ComEd’s goodwill has been assigned entirely to the ComEd reporting
unit. Exelon's and PHI’s goodwill has been assigned to the Pepco, DPL, and ACE reporting units in the amounts of $2.1 billion, $1.4 billion, and $0.5 billion,
respectively. See Note 13 — Intangible Assets of the Combined Notes to Consolidated Financial Statements for additional information.

Entities assessing goodwill for impairment have the option of first performing a qualitative assessment to determine whether a quantitative assessment is
necessary.  As  part  of  the  qualitative  assessments,  Exelon,  ComEd,  and  PHI  evaluate,  among  other  things,  management's  best  estimate  of  projected
operating  and  capital  cash  flows  for  their  businesses,  outcomes  of  recent  regulatory  proceedings,  changes  in  certain  market  conditions,  including  the
discount rate and regulated utility peer EBITDA multiples, and the passing margin from their last quantitative assessments performed.

Application  of  the  goodwill  impairment  assessment  requires  management  judgment,  including  the  identification  of  reporting  units  and  determining  the  fair
value of the reporting unit, which management estimates using a weighted combination of a discounted cash flow analysis and a market multiples analysis.
Significant  assumptions  used  in  these  fair  value  analyses  include  discount  and  growth  rates,  utility  sector  market  performance  and  transactions,  and
projected operating and capital cash flows for ComEd’s, Pepco's, DPL's, and ACE's businesses and the fair value of debt.

While  the  2020  annual  assessments  indicated  no  impairments,  certain  assumptions  used  in  the  assessment  are  highly  sensitive  to  changes.  Adverse
regulatory actions or changes in significant assumptions could potentially result in future impairments of Exelon’s, ComEd's, or PHI’s goodwill, which could
be material.

See Note 1 — Significant Accounting Policies and Note 13 — Intangible Assets of the Combined Notes to Consolidated Financial Statements for additional
information.

Unamortized Energy Contract Assets and Liabilities (Exelon, Generation, and PHI)

Unamortized  energy  contract  assets  and  liabilities  represent  the  remaining  unamortized  balances  of  non-derivative  energy  contracts  that  Generation  has
acquired and the electricity contracts Exelon acquired as part of the PHI merger. The initial amount recorded represents the fair value of the contracts at the
time  of  acquisition.  At  Exelon  and  PHI,  offsetting  regulatory  assets  or  liabilities  were  also  recorded  for  those  energy  contract  costs  that  are  probable  of
recovery  or  refund  through  customer  rates.  The  unamortized  energy  contract  assets  and  liabilities  and  any  corresponding  regulatory  assets  or  liabilities,
respectively, are amortized over the life of the contract in relation to the expected realization of the underlying cash flows. Amortization of the unamortized
energy  contract  assets  and  liabilities  is  recorded  through  purchased  power  and  fuel  expense  or  operating  revenues,  depending  on  the  nature  of  the
underlying contract. See Note 3 — Regulatory Matters and Note 13 — Intangible Assets of the Combined Notes to Consolidated Financial Statements for
additional information.

Impairment of Long-Lived Assets (All Registrants)

All  Registrants  regularly  monitor  and  evaluate  the  carrying  value  of  long-lived  assets  and  asset  groups  for  recoverability  whenever  events  or  changes  in
circumstances  indicate  that  the  carrying  value  of  those  assets  may  not  be  recoverable.  Indicators  of  potential  impairment  may  include  a  deteriorating
business climate, including, but not limited to, declines in energy prices, condition of the asset, an asset remaining idle for more than a short period of time,
specific regulatory disallowance, advances in technology, plans to dispose of a long-lived asset

72

Table of Contents

significantly before the end of its useful life, and financial distress of a third party for assets contracted with them on a long-term basis, among others.

The  review  of  long-lived  assets  and  asset  groups  for  impairment  utilizes  significant  assumptions  about  operating  strategies  and  estimates  of  future  cash
flows,  which  require  assessments  of  current  and  projected  market  conditions.  For  the  generation  business,  forecasting  future  cash  flows  requires
assumptions regarding forecasted commodity prices for the sale of power and purchases of fuel and the expected operations of assets. A variation in the
assumptions used could lead to a different conclusion regarding the recoverability of an asset or asset group and, thus, could potentially result in material
future impairments. An impairment evaluation is based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets
or asset groups are largely independent of the cash flows of other assets and liabilities. For the generation business, the lowest level of independent cash
flows is determined by the evaluation of several factors, including the geographic dispatch of the generation units and the hedging strategies related to those
units  as  well  as  the  associated  intangible  assets  or  liabilities  recorded  on  the  balance  sheet.  The  cash  flows  from  the  generating  units  are  generally
evaluated at a regional portfolio level with cash flows generated from the customer supply and risk management activities, including cash flows from related
intangible assets and liabilities on the balance sheet. In certain cases, generating assets may be evaluated on an individual basis where those assets are
contracted  on  a  long-term  basis  with  a  third  party  and  operations  are  independent  of  other  generating  assets  (typically  contracted  renewables).  For  such
assets the financial viability of the third party, including the impact of bankruptcy on the contract, may be a significant assumption in the assessment.

On a quarterly basis, Generation assesses its long-lived assets or asset groups for indicators of impairment. If indicators are present for a long-lived asset or
asset group, a comparison of the undiscounted expected future cash flows to the carrying value is performed. When the undiscounted cash flow analysis
indicates  the  carrying  value  of  a  long-lived  asset  or  asset  group  is  not  recoverable,  the  amount  of  the  impairment  loss  is  determined  by  measuring  the
excess of the carrying amount of the long-lived asset or asset group over its fair value. The fair value of the long-lived asset or asset group is dependent
upon a market participant’s view of the exit price of the assets. This includes significant assumptions of the estimated future cash flows generated by the
assets  and  market  discount  rates.  Events  and  circumstances  often  do  not  occur  as  expected  resulting  in  differences  between  prospective  financial
information  and  actual  results,  which  may  be  material.  The  determination  of  fair  value  is  driven  by  both  internal  assumptions  that  include  significant
unobservable inputs (Level 3) such as revenue and generation forecasts, projected capital, and maintenance expenditures and discount rates, as well as
information from various public, financial and industry sources.

See Note 12 — Asset Impairments of the Combined Notes to Consolidated Financial Statements for a discussion of asset impairment assessments.

Depreciable Lives of Property, Plant, and Equipment (All Registrants)

The Registrants have significant investments in electric generation assets and electric and natural gas transmission and distribution assets. These assets
are generally depreciated on a straight-line basis, using the group, composite, or unitary methods of depreciation. The group approach is typically for groups
of  similar  assets  that  have  approximately  the  same  useful  lives  and  the  composite  approach  is  used  for  heterogeneous  assets  that  have  different  lives.
Under both methods, a reporting entity depreciates the assets over the average life of the assets in the group. The estimation of asset useful lives requires
management  judgment,  supported  by  formal  depreciation  studies  of  historical  asset  retirement  experience.  Depreciation  studies  are  generally  completed
every five years, or more frequently if required by a rate regulator or if an event, regulatory action, or change in retirement patterns indicate an update is
necessary.

For  the  Utility  Registrants,  depreciation  studies  generally  serve  as  the  basis  for  amounts  allowed  in  customer  rates  for  recovery  of  depreciation  costs.
Generally, the Utility Registrants adjust their depreciation rates for financial reporting purposes concurrent with adjustments to depreciation rates reflected in
customer rates, unless the depreciation rates reflected in customer rates do not align with management’s judgment as to an appropriate estimated useful life
or have not been updated on a timely basis. Depreciation expense and customer rates for ComEd, BGE, Pepco, DPL, and ACE include an estimate of the
future costs of dismantling and removing plant from service upon retirement. See Note 3 — Regulatory Matters of the Combined Notes to the Consolidated
Financial Statements for information regarding regulatory liabilities and assets recorded by ComEd, BGE, Pepco, DPL, and ACE related to removal costs.

73

Table of Contents

PECO’s  removal  costs  are  capitalized  to  accumulated  depreciation  when  incurred,  and  recorded  to  depreciation  expense  over  the  life  of  the  new  asset
constructed consistent with PECO’s regulatory recovery method. Estimates for such removal costs are also evaluated in the periodic depreciation studies.

At Generation, along with depreciation study results, management considers expected future energy market conditions and generation plant operating costs
and capital investment requirements in determining the estimated service lives of its generating facilities and reassesses the reasonableness of estimated
useful lives whenever events or changes in circumstances warrant. When a determination has been made that an asset will be retired before the end of its
current  estimated  useful  life,  depreciation  provisions  will  be  accelerated  to  reflect  the  shortened  estimated  useful  life,  which  could  have  a  material
unfavorable  impact  on  Exelon’s  and  Generation’s  future  results  of  operations.  See  Note  7  —  Early  Plant  Retirements  of  the  Combined  Notes  to  the
Consolidated Financial Statements for additional information.

Changes in estimated useful lives of electric generation assets and of electric and natural gas transmission and distribution assets could have a significant
impact  on  the  Registrants’  future  results  of  operations.  See  Note  1  —  Significant  Accounting  Policies  of  the  Combined  Notes  to  Consolidated  Financial
Statements for information regarding depreciation and estimated service lives of the property, plant, and equipment of the Registrants.

Defined Benefit Pension and Other Postretirement Employee Benefits (All Registrants)

Exelon sponsors defined benefit pension plans and OPEB plans for substantially all current employees. The measurement of the plan obligations and costs
of  providing  benefits  involves  various  factors,  including  the  development  of  valuation  assumptions  and  inputs  and  accounting  policy  elections.  When
developing  the  required  assumptions,  Exelon  considers  historical  information  as  well  as  future  expectations.  The  measurement  of  benefit  obligations  and
costs is affected by several assumptions including the discount rate, the long-term expected rate of return on plan assets, the anticipated rate of increase of
health care costs, Exelon's contributions, the rate of compensation increases, and the long-term expected investment rate credited to employees of certain
plans, among others. The assumptions are updated annually and upon any interim remeasurement of the plan obligations.

Pension  and  OPEB  plan  assets  include  equity  securities,  including  U.S.  and  international  securities,  and  fixed  income  securities,  as  well  as  certain
alternative investment classes such as real estate, private equity, and hedge funds.

Expected Rate of Return on Plan Assets. In determining the EROA, Exelon considers historical economic indicators (including inflation and GDP growth)
that impact asset returns, as well as expectation regarding future long-term capital market performance, weighted by Exelon’s target asset class allocations.
Exelon calculates the amount of expected return on pension and OPEB plan assets by multiplying the EROA by the MRV of plan assets at the beginning of
the year, taking into consideration anticipated contributions and benefit payments to be made during the year. In determining MRV, the authoritative guidance
for pensions and postretirement benefits allows the use of either fair value or a calculated value that recognizes changes in fair value in a systematic and
rational manner over not more than five years. For the majority of pension plan assets, Exelon uses a calculated value that adjusts for 20% of the difference
between fair value and expected MRV of plan assets. Use of this calculated value approach enables less volatile expected asset returns to be recognized as
a component of pension cost from year to year. For OPEB plan assets and certain pension plan assets, Exelon uses fair value to calculate the MRV.

Discount Rate. The discount rates are determined by developing a spot rate curve based on the yield to maturity of a universe of high-quality non-callable
(or callable with make whole provisions) bonds with similar maturities to the related pension and OPEB obligations. The spot rates are used to discount the
estimated future benefit distribution amounts under the pension and OPEB plans. The discount rate is the single level rate that produces the same result as
the spot rate curve. Exelon utilizes an analytical tool developed by its actuaries to determine the discount rates.

Mortality. The mortality assumption is composed of a base table that represents the current expectation of life expectancy of the population adjusted by an
improvement scale that attempts to anticipate future improvements in life expectancy. Exelon’s mortality assumption utilizes the SOA 2019 base table (Pri-
2012) and MP-2020 improvement scale adjusted to use Proxy SSA ultimate improvement rates.

In  general,  the  discount  rate  will  have  a  larger  impact  on  the  pension  and  OPEB  cost  and  obligation  as  the  rate  moves  closer  to  0%.  Therefore,  the  discount  rate
sensitivities  above  cannot  necessarily  be  extrapolated  for  larger  increases  or  decreases  in  the  discount  rate.  Additionally,  Exelon  utilizes  a  liability-driven  investment
strategy for its pension asset portfolio. The sensitivities shown above do not reflect the offsetting impact that changes in discount rates may have on pension asset returns.

See  Note  1  —  Significant  Accounting  Policies  and  Note  15  —  Retirement  Benefits  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information regarding the accounting for the defined benefit pension plans and OPEB plans.

Regulatory Accounting (Exelon and Utility Registrants)

For their regulated electric and gas operations, Exelon and the Utility Registrants reflect the effects of cost-based rate regulation in their financial statements,
which  is  required  for  entities  with  regulated  operations  that  meet  the  following  criteria:  (1)  rates  are  established  or  approved  by  a  third-party  regulator;
(2) rates are designed to recover the entities’ cost of providing services or products; and (3) a reasonable expectation that rates designed to recover costs
can  be  charged  to  and  collected  from  customers.  Regulatory  assets  represent  incurred  costs  that  have  been  deferred  because  of  their  probable  future
recovery from customers through regulated rates. Regulatory liabilities represent (1) revenue or gains that have been deferred because it is probable such
amounts  will  be  returned  to  customers  through  future  regulated  rates;  or  (2)  billings  in  advance  of  expenditures  for  approved  regulatory  programs.  If  it  is
concluded in a future period that a separable portion of operations no longer meets the criteria discussed above, Exelon and the Utility Registrants would be
required  to  eliminate  any  associated  regulatory  assets  and  liabilities  and  the  impact,  which  could  be  material,  would  be  recognized  in  the  Consolidated
Statements of Operations and Comprehensive Income.

The following table illustrates the gains (losses) that could result from the elimination of regulatory assets and liabilities and charges against OCI (dollars in
millions  before  taxes)  related  to  deferred  costs  associated  with  Exelon's  pension  and  OPEB  plans  that  are  recorded  as  regulatory  assets  in  Exelon's

See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  regarding  regulatory  matters,
including the regulatory assets and liabilities tables of Exelon and the Utility Registrants.

For  each  regulatory  jurisdiction  in  which  they  conduct  business,  Exelon  and  the  Utility  Registrants  assess  whether  the  regulatory  assets  and  liabilities
continue to meet the criteria for probable future recovery or refund at each balance sheet date and when regulatory events occur. This assessment includes
consideration  of  recent  rate  orders,  historical  regulatory  treatment  for  similar  costs  in  each  Registrant's  jurisdictions,  and  factors  such  as  changes  in
applicable  regulatory  and  political  environments.  If  the  assessments  and  estimates  made  by  Exelon  and  the  Utility  Registrants  for  regulatory  assets  and
regulatory liabilities are ultimately different than actual regulatory outcomes, the impact in their consolidated financial statements could be material.

Refer  to  the  revenue  recognition  discussion  below  for  additional  information  on  the  annual  revenue  reconciliations  associated  with  ICC-approved  electric
distribution and energy efficiency formula rates for ComEd, and FERC transmission formula rate tariffs for the Utility Registrants.

Accounting for Derivative Instruments (All Registrants)

The  Registrants  use  derivative  instruments  to  manage  commodity  price  risk,  foreign  currency  exchange  risk,  and  interest  rate  risk  related  to  ongoing
business  operations.  The  Registrants’  derivative  activities  are  in  accordance  with  Exelon’s  Risk  Management  Policy  (RMP).  See  Note  16  —  Derivative
Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional information.

The  Registrants  account  for  derivative  financial  instruments  under  the  applicable  authoritative  guidance.  Determining  whether  a  contract  qualifies  as  a
derivative requires that management exercise significant judgment, including assessing market liquidity as well as determining whether a contract has one or
more underlyings and one or more notional quantities. Changes in management’s assessment of contracts and the liquidity of their markets, and changes in
authoritative guidance, could result in previously excluded contracts becoming in scope of new authoritative guidance.

All derivatives are recognized on the balance sheet at their fair value, except for certain derivatives that qualify for, and are elected under, NPNS. Derivatives
entered  into  for  economic  hedging  and  for  proprietary  trading  purposes  are  recorded  at  fair  value  through  earnings.  For  economic  hedges  that  are  not
designated  for  hedge  accounting  for  the  Utility  Registrants,  changes  in  the  fair  value  each  period  are  generally  recorded  with  a  corresponding  offsetting
regulatory asset or liability given likelihood of recovering the associated costs through customer rates.

NPNS.  As  part  of  Generation’s  energy  marketing  business,  Generation  enters  into  contracts  to  buy  and  sell  energy  to  meet  the  requirements  of  its
customers.  These  contracts  include  short-term  and  long-term  commitments  to  purchase  and  sell  energy  and  energy-related  products  in  the  retail  and
wholesale markets with the intent and ability to deliver or take delivery. While some of these contracts are considered derivative financial instruments under
the authoritative guidance, certain of these qualifying transactions have been designated by Generation as NPNS transactions, which are thus not required
to  be  recorded  at  fair  value,  but  rather  on  an  accrual  basis  of  accounting.  Determining  whether  a  contract  qualifies  for  the  NPNS  requires  judgment  on
whether  the  contract  will  physically  deliver  and  requires  that  management  ensure  compliance  with  all  of  the  associated  qualification  and  documentation
requirements. Revenues and expenses on contracts that qualify as NPNS are recognized when the underlying physical transaction is completed. Contracts
that qualify for the NPNS are those for which physical delivery is probable, quantities are expected to be used or sold in the normal course of business over
a reasonable period of time, and the contract is not financially settled on a net basis. The contracts that ComEd has entered into with suppliers as part of
ComEd’s energy procurement process, PECO’s full requirement contracts under the PAPUC-approved DSP program, most of PECO’s natural gas supply
agreements,  all  of  BGE’s  full  requirement  contracts  and  natural  gas  supply  agreements  that  are  derivatives,  and  certain  Pepco,  DPL,  and  ACE  full
requirement contracts qualify for and are accounted for under the NPNS.

Commodity Contracts. Identification of a commodity contract as an economic hedge requires Generation to determine that the contract is in accordance
with the RMP. Generation reassesses its economic hedges on a regular basis to determine if they continue to be within the guidelines of the RMP.

76

Table of Contents

As a part of the authoritative guidance, the Registrants make estimates and assumptions concerning future commodity prices, load requirements, interest
rates,  the  timing  of  future  transactions  and  their  probable  cash  flows,  the  fair  value  of  contracts  and  the  expected  changes  in  the  fair  value  in  deciding
whether  or  not  to  enter  into  derivative  transactions,  and  in  determining  the  initial  accounting  treatment  for  derivative  transactions.  Under  the  authoritative
guidance  for  fair  value  measurements,  the  Registrants  categorize  these  derivatives  under  a  fair  value  hierarchy  that  prioritizes  the  inputs  to  valuation
techniques used to measure fair value.

Derivative contracts are traded in both exchange-based and non-exchange-based markets. Exchange-based derivatives that are valued using unadjusted
quoted prices in active markets are generally categorized in Level 1 in the fair value hierarchy.

Certain derivatives’ pricing is verified using indicative price quotations available through brokers or over-the-counter, on-line exchanges. The price quotations
reflect the average of the bid-ask mid-point from markets that the Registrants believe provide the most liquid market for the commodity. The price quotations
are  reviewed  and  corroborated  to  ensure  the  prices  are  observable  and  representative  of  an  orderly  transaction  between  market  participants.  The
Registrant’s derivatives are traded predominately at liquid trading points. The remaining derivative contracts are valued using models that consider inputs
such as contract terms, including maturity, and market parameters, and assumptions of the future prices of energy, interest rates, volatility, credit worthiness,
and  credit  spread.  For  derivatives  that  trade  in  liquid  markets,  such  as  generic  forwards,  swaps,  and  options,  the  model  inputs  are  generally  observable.
Such instruments are categorized in Level 2.

For derivatives that trade in less liquid markets with limited pricing information, the model inputs generally would include both observable and unobservable
inputs and are categorized in Level 3.

The Registrants consider nonperformance risk, including credit risk in the valuation of derivative contracts, including both historical and current market data
in its assessment of nonperformance risk, including credit risk. The impacts of nonperformance and credit risk to date have generally not been material to the
financial statements.

See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK and Note 18 — Fair Value of Financial Assets and Liabilities
and  Note  16  —  Derivative  Financial  Instruments  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  regarding  the
Registrants’ derivative instruments.

Taxation (All Registrants)

Significant  management  judgment  is  required  in  determining  the  Registrants’  provisions  for  income  taxes,  primarily  due  to  the  uncertainty  related  to  tax
positions taken, as well as deferred tax assets and liabilities and valuation allowances. The Registrants account for uncertain income tax positions using a
benefit recognition model with a two-step approach including a more-likely-than-not recognition threshold and a measurement approach based on the largest
amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement. Management evaluates each position based solely on the
technical  merits  and  facts  and  circumstances  of  the  position,  assuming  the  position  will  be  examined  by  a  taxing  authority  having  full  knowledge  of  all
relevant information. Significant judgment is required to determine whether the recognition threshold has been met and, if so, the appropriate amount of tax
benefits to be recorded in the Registrants’ consolidated financial statements.

The Registrants evaluate quarterly the probability of realizing deferred tax assets by reviewing a forecast of future taxable income and their intent and ability
to implement tax planning strategies, if necessary, to realize deferred tax assets. The Registrants also assess negative evidence, such as the expiration of
historical operating loss or tax credit carryforwards, that could indicate the Registrant's inability to realize its deferred tax assets. Based on the combined
assessment,  the  Registrants  record  valuation  allowances  for  deferred  tax  assets  when  it  is  more-likely-than-not  such  benefit  will  not  be  realized  in  future
periods.

Actual  income  taxes  could  vary  from  estimated  amounts  due  to  the  future  impacts  of  various  items,  including  future  changes  in  income  tax  laws,  the
Registrants’ forecasted financial condition and results of operations, failure to successfully implement tax planning strategies, as well as results of audits and
examinations  of  filed  tax  returns  by  taxing  authorities.  See  Note  14  —  Income  Taxes  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information.

Accounting for Loss Contingencies (All Registrants)

In the preparation of their financial statements, the Registrants make judgments regarding the future outcome of contingent events and record liabilities for
loss contingencies that are probable and can be reasonably estimated based upon available information. The amount recorded may differ from the actual
expense incurred when the uncertainty is resolved. Such difference could have a significant impact in the Registrants' consolidated financial statements.

Environmental Costs. Environmental investigation and remediation liabilities are based upon estimates with respect to the number of sites for which the
Registrants will be responsible, the scope and cost of work to be performed at each site, the portion of costs that will be shared with other parties, the timing
of the remediation work and changes in technology, regulations, and the requirements of local governmental authorities. Annual studies and/or reviews are
conducted  at  ComEd,  PECO,  BGE,  and  DPL  to  determine  future  remediation  requirements  for  MGP  sites  and  estimates  are  adjusted  accordingly.  In
addition, periodic reviews are performed at each of the Registrants to assess the adequacy of other environmental reserves. These matters, if resolved in a
manner different from the estimate, could have a significant impact in the Registrants’ consolidated financial statements. See Note 19 — Commitments and

Other,  Including Personal Injury Claims.  The  Registrants  are  self-insured  for  general  liability,  automotive  liability,  workers’  compensation,  and  personal
injury claims to the extent that losses are within policy deductibles or exceed the amount of insurance maintained. The Registrants have reserves for both
open  claims  asserted  and  an  estimate  of  claims  incurred  but  not  reported  (IBNR).  The  IBNR  reserve  is  estimated  based  on  actuarial  assumptions  and
analysis and is updated annually. Future events, such as the number of new claims to be filed each year, the average cost of disposing of claims, as well as
the numerous uncertainties surrounding litigation and possible state and national legislative measures could cause the actual costs to be higher or lower
than estimated. Accordingly, these claims, if resolved in a manner different from the estimate, could have a material impact in the Registrants’ consolidated
financial statements.

Revenue Recognition (All Registrants)

Sources of Revenue and Determination of Accounting Treatment. The Registrants earn revenues from various business activities including: the sale of
power  and  energy-related  products,  such  as  natural  gas,  capacity,  and  other  commodities  in  non-regulated  markets  (wholesale  and  retail);  the  sale  and
delivery of power and natural gas in regulated markets; and the provision of other energy-related non-regulated products and services.

The accounting treatment for revenue recognition is based on the nature of the underlying transaction and applicable authoritative guidance. The Registrants
primarily apply the Revenue from Contracts with Customers, Derivative and ARP guidance to recognize revenue as discussed in more detail below.

Revenue from Contracts with Customers. The Registrants recognize revenues in the period in which the performance obligations within contracts with
customers are satisfied, which generally occurs when power, natural gas, and other energy-related commodities are physically delivered to the customer.
Transactions of the Registrants within the scope of Revenue from Contracts with Customers generally include non-derivative agreements, contracts that are
designated as NPNS, sales to utility customers under regulated service tariffs, and spot-market energy commodity sales, including settlements with ISOs.

The determination of Generation’s and the Utility Registrants' retail power and natural gas sales to individual customers is based on systematic readings of
customer meters, generally on a monthly basis. At the end of each month, amounts of energy delivered to customers since the date of the last meter reading
are estimated, and corresponding unbilled revenue is recorded. The measurement of unbilled revenue is affected by the following factors: daily customer
usage measured by generation or gas throughput volume, customer usage by class, losses of energy during delivery to customers and applicable customer
rates.  Increases  or  decreases  in  volumes  delivered  to  the  utilities’  customers  and  favorable  or  unfavorable  rate  mix  due  to  changes  in  usage  patterns  in
customer  classes  in  the  period  could  be  significant  to  the  calculation  of  unbilled  revenue.  In  addition,  revenues  may  fluctuate  monthly  as  a  result  of
customers electing to use an alternate supplier, since unbilled commodity revenues are not recorded for these customers. Changes in the timing of meter
reading  schedules  and  the  number  and  type  of  customers  scheduled  for  each  meter  reading  date  also  impact  the  measurement  of  unbilled  revenue;
however,  total  operating  revenues  would  remain  materially  unchanged.  See  Note  1  —  Significant  Accounting  Policies  of  the  Combined  Notes  to
Consolidated Financial Statements for additional information.

Derivative Revenues. The Registrants record revenues and expenses using the mark-to-market method of accounting for transactions that are accounted
for  as  derivatives.  These  derivative  transactions  primarily  relate  to  commodity  price  risk  management  activities.  Mark-to-market  revenues  and  expenses
include: inception gains or losses on new transactions where the fair value is observable, unrealized gains and losses from changes in the fair value of open
contracts, and realized gains and losses.

Alternative  Revenue  Program  Accounting.  Certain  of  the  Utility  Registrants’  ratemaking  mechanisms  qualify  as  ARPs  if  they  (i)  are  established  by  a
regulatory order and allow for automatic adjustment to future rates, (ii) provide for additional revenues (above those amounts currently reflected in the price
of utility service) that are objectively determinable and probable of recovery, and (iii) allow for the collection of those additional revenues within 24 months
following the end of the period in which they were recognized. For mechanisms that meet these criteria, which include the Utility Registrants’ formula rate
mechanisms  and  revenue  decoupling  mechanisms,  the  Utility  Registrants  adjust  revenue  and  record  an  offsetting  regulatory  asset  or  liability  once  the
condition  or  event  allowing  additional  billing  or  refund  has  occurred.  The  ARP  revenues  presented  in  the  Utility  Registrants’  Consolidated  Statements  of
Operations  and  Comprehensive  Income  include  both:  (i)  the  recognition  of  “originating”  ARP  revenues  (when  the  regulator-specified  condition  or  event
allowing  for  additional  billing  or  refund  has  occurred)  and  (ii)  an  equal  and  offsetting  reversal  of  the  “originating”  ARP  revenues  as  those  amounts  are
reflected in the price of utility service and recognized as Revenue from Contracts with Customers.

ComEd  records  ARP  revenue  for  its  best  estimate  of  the  electric  distribution,  energy  efficiency,  distributed  generation  rebates,  and  transmission  revenue
impacts  resulting  from  future  changes  in  rates  that  ComEd  believes  are  probable  of  approval  by  the  ICC  and  FERC  in  accordance  with  its  formula  rate
mechanisms. BGE, Pepco, and DPL record ARP revenue for their best estimate of the electric and natural gas distribution revenue impacts resulting from
future changes in rates that they believe are probable of approval by the MDPSC and/or DCPSC in accordance with their revenue decoupling mechanisms.
PECO, BGE, Pepco, DPL, and ACE record ARP revenue for their best estimate of the transmission revenue impacts resulting from future changes in rates

Table of Contents

that they believe are probable of approval by FERC in accordance with their formula rate mechanisms. Estimates of the current year revenue requirement
are based on actual and/or forecasted costs and investments in rate base for the period and the rates of return on common equity and associated regulatory
capital  structure  allowed  under  the  applicable  tariff.  The  estimated  reconciliation  can  be  affected  by,  among  other  things,  variances  in  costs  incurred,
investments made, allowed ROE, and actions by regulators or courts.

See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

Allowance for Credit Losses on Customer Accounts Receivable (Utility Registrants)

Utility Registrants estimate the allowance for credit losses on customer receivables by applying loss rates developed specifically for each company based on
historical  loss  experience,  current  conditions,  and  forward-looking  risk  factors  to  the  outstanding  receivable  balance  by  customer  risk  segment.  Risk
segments  represent  a  group  of  customers  with  similar  forward-looking  credit  quality  indicators  and  risk  factors  that  are  comprised  based  on  various
attributes, including delinquency of their balances and payment history and represent expected, future customer behavior. Loss rates applied to the accounts
receivable balances are based on a historical average of charge-offs as a percentage of accounts receivable in each risk segment. The Utility Registrants'
customer accounts are generally considered delinquent if the amount billed is not received by the time the next bill is issued, which normally occurs on a
monthly  basis.  Utility  Registrants'  customer  accounts  are  written  off  consistent  with  approved  regulatory  requirements.  Utility  Registrants'  allowances  for
credit  losses  will  continue  to  be  affected  by  changes  in  volume,  prices,  and  economic  conditions  as  well  as  changes  in  ICC,  PAPUC,  MDPSC,  DCPSC,
DPSC, and NJBPU regulations.

Revenues Net of Purchased Power and Fuel Expense. The  basis  for  Generation's  reportable  segments  is  the  integrated  management  of  its  electricity
business that is located in different geographic regions, and largely representative of the footprints of ISO/RTO and/or NERC regions, which utilize multiple
supply sources to provide electricity through various distribution channels (wholesale and retail). Generation's hedging strategies and risk metrics are also
aligned  with  these  same  geographic  regions.  Generation's  five  reportable  segments  are  Mid-Atlantic,  Midwest,  New  York,  ERCOT,  and  Other  Power
Regions. See Note 5 — Segment Information of the Combined Notes to Consolidated Financial Statements for additional information on these reportable
segments.

The following business activities are not allocated to a region and are reported under Other: natural gas, as well as other miscellaneous business activities
that are not significant to overall operating revenues or results of operations. Further, the following activities are not allocated to a region and are reported in
Other: accelerated nuclear fuel amortization associated with nuclear decommissioning; and other miscellaneous revenues.

Generation  evaluates  the  operating  performance  of  electric  business  activities  using  the  measure  of  RNF.  Operating  revenues  include  all  sales  to  third
parties  and  affiliated  sales  to  the  Utility  Registrants.  Purchased  power  costs  include  all  costs  associated  with  the  procurement  and  supply  of  electricity
including capacity, energy,

Nuclear  Fleet  Capacity  Factor.  The  following  table  presents  nuclear  fleet  operating  data  for  the  Generation-operated  plants,  which  reflects  ownership
percentage of stations operated by Exelon, excluding Salem, which is operated by PSEG. The nuclear fleet capacity factor presented in the table is defined

Combined Notes to Consolidated Financial Statements for additional information.

Equity in losses of unconsolidated affiliates for the year ended December 31, 2020 compared to the same period in 2019 increased primarily due to the
impairment of equity method investments in certain distributed energy companies in the third quarter of 2019.

Net income attributable to noncontrolling interests for the year ended December 31, 2020 compared to the same period in 2019 decreased primarily due

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019. Net income decreased by $250 million primarily due to payments that
ComEd made under the Deferred Prosecution Agreement, an impairment charge resulting from acquisition of transmission assets, and lower allowed electric
distribution ROE due to a decrease in treasury rates, partially offset by higher electric distribution formula rate earnings (reflecting the impacts of higher rate
base). See Note 19 — Commitments and Contingencies of the Combined Notes to Consolidated Financial Statements for additional information related to

Energy Efficiency Revenue. FEJA provides for a performance-based formula rate, which requires an annual reconciliation of the revenue requirement in
effect to the actual costs that the ICC determines are prudently and reasonably incurred in a given year. Under FEJA, energy efficiency revenue varies from
year to year based upon fluctuations in the underlying costs, investments being recovered, and allowed ROE. Energy efficiency revenue increased for the
year ended December 31, 2020, as compared to the same period in 2019, primarily due to increased regulatory asset amortization which is fully recoverable.
See  Depreciation  and  amortization  expense  discussions  below  and  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial
Statements for additional information.

Distribution Revenue. EIMA and FEJA provide for a performance-based formula rate, which requires an annual reconciliation of the revenue requirement in
effect to the actual costs that the ICC determines are prudently and reasonably incurred in a given year. Electric distribution revenue varies from year to year
based upon fluctuations in the underlying costs (e.g., severe weather and storm restoration), investments being recovered, and allowed ROE. During the
year ended December 31, 2020, as compared to the same period in 2019, electric distribution revenue increased due to the impact of higher rate base and
higher fully recoverable costs, offset by lower allowed ROE due to a decrease in treasury rates. See Note 3 — Regulatory Matters of the Combined Notes to
Consolidated Financial Statements for additional information.

Transmission Revenue. Under a FERC-approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs,
capital  investments  being  recovered,  and  the  highest  daily  peak  load,  which  is  updated  annually  in  January  based  on  the  prior  calendar  year.  Generally,
increases/decreases in the highest daily peak load will result in higher/lower transmission revenue. During the year ended December 31, 2020, as compared
to the same period in 2019, transmission revenues remained relatively consistent. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated
Financial Statements for additional information.

Other Revenue primarily  includes  assistance  provided  to  other  utilities  through  mutual  assistance  programs.  The  increase  in  Other  revenue  for  the  year
ended December 31, 2020, as compared to the same period in 2019, primarily reflects mutual assistance revenues associated with storm restoration efforts.

Regulatory Required Programs represents revenues collected under approved riders to recover costs incurred for regulatory programs such as recoveries
under the credit loss expense tariff, environmental costs associated with MGP sites, and costs related to electricity, ZEC, and REC procurement. The riders
are designed to provide full and current cost recovery. The costs of these programs are included in Purchased power expense, Operating and maintenance
expense, Depreciation and amortization expense, and Taxes other than income. Customers have the choice to purchase electricity from competitive electric
generation suppliers. Customer choice programs do not impact the volume of deliveries as ComEd remains the distribution service provider for all customers
and charges a regulated rate for distribution service, which is recorded in Operating revenues. For customers that choose to purchase electric generation
from competitive suppliers, ComEd acts as the billing agent and therefore does not record Operating revenues or Purchased power expense related to the
electricity.  For  customers  that  choose  to  purchase  electric  generation  from  ComEd,  ComEd  is  permitted  to  recover  the  electricity,  ZEC,  and  REC
procurement costs without mark-up and therefore records equal and offsetting amounts in Operating revenues and Purchased power expense related to the
electricity, ZECs, and RECs.

See Note 5 — Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of ComEd's revenue disaggregation.

The increase of $57 million for the year ended December 31, 2020, as compared to the same period in 2019, in Purchased power expense is  offset  in
Operating revenues as part of regulatory required programs.

Weather. The demand for electricity and natural gas is affected by weather conditions. With respect to the electric business, very warm weather in summer
months and, with respect to the electric and natural gas businesses, very cold weather in winter months are referred to as “favorable weather conditions”
because these weather conditions result in increased deliveries of electricity and natural gas. Conversely, mild weather reduces demand. For the year ended
December  31,  2020  compared  to  the  same  period  in  2019,  Operating  revenues  related  to  weather  decreased  due  to  the  impact  of  unfavorable  weather
conditions in PECO's service territory.

Heating and cooling degree days are quantitative indices that reflect the demand for energy needed to heat or cool a home or business. Normal weather is
determined  based  on  historical  average  heating  and  cooling  degree  days  for  a  30-year  period  in  PECO’s  service  territory.  The  changes  in  heating  and
cooling  degree  days  in  PECO’s  service  territory  for  the  years  ended  December  31,  2020  compared  to  the  same  period  in  2019  and  normal  weather
consisted of the following:

Volume. Electric volume, exclusive of the effects of weather, for the year ended December 31, 2020 compared to the same period in 2019, increased due to
an increase in usage for residential customers during COVID-19 further increased by customer growth. Natural gas volume for the year ended December 31,
2020 compared to the same period in 2019, decreased on a net basis due to a decrease in usage for the commercial and industrial natural gas classes
during COVID-19.

Pricing  for  the  year  ended  December  31,  2020  compared  to  the  same  period  in  2019  increased  primarily  due  to  higher  overall  effective  rates  due  to
decreased usage across all major customer classes. Additionally, the increase represents revenue from higher natural gas distribution rates.

Transmission Revenue. Under a FERC approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs
and capital investments being recovered. PECO's transmission formula rate filing was approved in the fourth quarter of 2019.

Other Revenue primarily includes revenue related to late payment charges. Other revenues for the year ended December 31, 2020 compared to the same
period in 2019, decreased as PECO ceased new late fees for all customers and restored service to customers upon request who were disconnected in the
last twelve months beginning March of 2020.

Regulatory Required Programs  represents  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  energy
efficiency, PGC, and the GSA. The riders are designed to provide full and current cost recovery as well as a return. The costs of these programs are included
in Purchased power and fuel expense, Operating and maintenance expense, Depreciation and amortization expense, and Income taxes. Customers have
the choice to purchase electricity and natural gas from competitive electric generation and natural gas suppliers. Customer choice programs do not impact
the volume of deliveries as PECO remains the distribution service provider for all customers and charges a regulated rate for distribution service, which is
recorded in Operating revenues. For customers that choose to purchase electric generation or natural gas from competitive suppliers, PECO acts as the
billing  agent  and  therefore  does  not  record  Operating  revenues  or  Purchased  power  and  fuel  expense  related  to  the  electricity  and/or  natural  gas.  For
customers  that  choose  to  purchase  electric  generation  or  natural  gas  from  PECO,  PECO  is  permitted  to  recover  the  electricity,  natural  gas,  and  REC
procurement  costs  without  mark-up  and  therefore  records  equal  and  offsetting  amounts  in  Operating  revenues  and  Purchased  power  and  fuel  expense
related to the electricity, natural gas, and RECs.

See Note 5—Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of PECO's revenue disaggregation.

Revenue  Decoupling.  The  demand  for  electricity  and  natural  gas  is  affected  by  weather  and  customer  usage.  However,  Operating  revenues  are  not
impacted  by  abnormal  weather  or  usage  per  customer  as  a  result  of  a  bill  stabilization  adjustment  (BSA)  that  provides  for  a  fixed  distribution  charge  per
customer by customer class. While Operating revenues are not impacted by abnormal weather or usage per customer, they are impacted by changes in the
number of customers.

Distribution Revenue increased for the year ended December 31, 2020 compared to the same period in 2019, primarily due to the impact of higher natural
gas and electric distribution rates that became effective in December 2019.

Transmission Revenue. Under a FERC-approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs,
capital  investments  being  recovered,  and  the  highest  daily  peak  load,  which  is  updated  annually  in  January  based  on  the  prior  calendar  year.  Generally,
increases/decreases  in  the  highest  daily  peak  load  will  result  in  higher/lower  transmission  revenue.  Transmission  revenue  decreased  for  the  year  ended
December 31, 2020 compared to the same period in 2019, primarily due to the settlement agreement of transmission-related income tax regulatory liabilities,
partially  offset  by  higher  fully  recoverable  costs.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information.

Other  Revenue  includes  revenue  related  to  late  payment  charges,  mutual  assistance,  off-system  sales,  and  service  application  fees.  Other  revenue
decreased for the year ended December 31, 2020 compared to the same period in 2019, as BGE temporarily suspended customer disconnections for non-
payment  beginning  March  of  2020  and  temporarily  ceased  new  late  fees  for  all  customers  and  restored  service  to  customers  upon  request  who  were
disconnected in the last twelve months.

Regulatory  Required  Programs  represent  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as
conservation, demand response, STRIDE, and the POLR mechanism. The riders are designed to provide full and current cost recovery, as well as a return in
certain instances. The costs of these programs are included in Purchased power and fuel expense, Operating and maintenance expense, Depreciation and
amortization  expense,  and  Taxes  other  than  income  taxes.  Customers  have  the  choice  to  purchase  electricity  and  natural  gas  from  competitive  electric
generation and natural gas suppliers. Customer choice programs do not impact the volume of deliveries as BGE remains the distribution service provider for
all customers and charges a regulated rate for distribution service, which is recorded in Operating revenues. For customers that choose to purchase electric
generation or natural gas from competitive suppliers, BGE acts as the billing agent and therefore does not record Operating revenues or Purchased power
and fuel expense related to the electricity and/or natural gas. For customers that choose to purchase electric generation or natural gas from BGE, BGE is
permitted  to  recover  the  electricity  and  natural  gas  procurement  costs  from  customers  and  therefore  records  the  amounts  related  to  the  electricity  and/or
natural gas in Operating revenues and Purchased power and fuel expense. BGE recovers electricity and natural gas procurement costs from customers with
a slight mark-up.

and decreased expense resulting from an absence of an increase in environmental liabilities, and a gain on sale of land at Pepco in the fourth quarter of
2020,  partially  offset  by  an  increase  in  depreciation  and  amortization  expense,  an  increase  in  DPL  storm  costs  related  to  the  August  2020  storms  in
Delaware, an increase in credit loss expense primarily as a result of suspending customer disconnections partially offset by the regulatory asset recorded in
2020 related to incremental credit loss expense due to COVID-19, and unfavorable weather conditions in ACE and DPL Delaware's service territories.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019. Net income increased by $23 million primarily due to decreased expense
resulting from an absence of an increase in environmental liabilities, increased electric distribution revenues, and a gain on sale of land in the fourth quarter
of 2020, partially offset by an increase in depreciation and amortization expense and an increase in credit loss expense primarily as a result of suspending

Revenue Decoupling. The demand for electricity is affected by weather and customer usage. However, Operating revenues from electric distribution in both
Maryland and the District of Columbia are not impacted by abnormal weather or usage per customer as a result of a bill stabilization adjustment (BSA) that
provides  for  a  fixed  distribution  charge  per  customer  by  customer  class.  While  Operating  revenues  are  not  impacted  by  abnormal  weather  or  usage  per
customer, they are impacted by changes in the number of customers.

Distribution Revenue increased for the year ended December 31, 2020 compared to the same period in 2019, primarily due to higher electric distribution
rates in Maryland that became effective in August 2019 and customer growth in the District of Columbia.

Transmission Revenue. Under a FERC-approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs,
capital  investments  being  recovered,  and  the  highest  daily  peak  load,  which  is  updated  annually  in  January  based  on  the  prior  calendar  year.  Generally,
increases/decreases  in  the  highest  daily  peak  load  will  result  in  higher/lower  transmission  revenue.  Transmission  revenue  decreased  for  the  year  ended
December 31, 2020 compared to the same period in 2019 primary due to the settlement agreement of transmission-related income tax regulatory liabilities.
See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information.

Other  Revenue  includes  rental  revenue,  revenue  related  to  late  payment  charges,  mutual  assistance  revenues,  and  recoveries  of  other  taxes.  Other
revenue decreased for the year ended December 31, 2020 compared to the same period in 2019, as Pepco temporarily suspended customer disconnections
for non-payment beginning March of 2020 and temporarily ceased new late fees for all customers and restored services to customers upon request who
were disconnected in the last twelve months.

Regulatory  Required  Programs  represent  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  energy
efficiency programs, DC PLUG, and SOS procurement and administrative costs. The riders are designed to provide full and current cost recovery as well as
a return in certain instances. The costs of these programs are included in Purchased power expense, Operating and maintenance expense, Depreciation
and  amortization  expense,  and  Taxes  other  than  income  taxes.  Customers  have  the  choice  to  purchase  electricity  from  competitive  electric  generation
suppliers.  Customer  choice  programs  do  not  impact  the  volume  of  deliveries,  as  Pepco  remains  the  distribution  service  provider  for  all  customers  and
charges a regulated rate for distribution service, which is recorded in Operating revenues. For customers that choose to purchase electric generation from
competitive  suppliers,  Pepco  acts  as  the  billing  agent  and  therefore  does  not  record  Operating  revenues  or  Purchased  power  expense  related  to  the
electricity. For customers that choose to purchase electric generation from Pepco, Pepco is permitted to recover the electricity and REC procurement costs
from  customers  and  therefore  records  the  amounts  related  to  the  electricity  and  RECs  in  Operating  revenues  and  Purchased  power  expense.  Pepco
recovers electricity and REC procurement costs from customers with a slight mark-up.

See Note 5 - Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of Pepco's revenue disaggregation.

The decrease of $63 million for the year ended December 31, 2020 compared to the same period in 2019, in Purchased power expense is fully offset in
Operating revenues as part of regulatory required programs.

Interest expense, net increased for the year ended December 31, 2020 compared to the same period in 2019, primarily due to issuance of debt in June
2019, February 2020, and June 2020.

Gain on sales of assets for the year ended December 31, 2020 compared to the year ended December 31, 2019 increased due the sale of land in the
fourth quarter of 2020.

Effective income tax rates were (2.7)% and 6.2% for the years ended December 31, 2020 and 2019, respectively. The change is primarily related to the
settlement agreement of ongoing transmission-related income tax regulatory liabilities. See Note 3 — Regulatory Matters and Note 14 — Income Taxes of
the Combined Notes to Consolidated Financial Statements for additional information regarding the components of the change in effective income tax rates.

Revenue  Decoupling.  The  demand  for  electricity  is  affected  by  weather  and  customer  usage.  However,  Operating  revenues  from  electric  distribution  in
Maryland  are  not  impacted  by  abnormal  weather  or  usage  per  customer  as  a  result  of  a  bill  stabilization  adjustment  (BSA)  that  provides  for  a  fixed
distribution charge per customer by customer class. While Operating revenues from electric distribution in Maryland are not impacted by abnormal weather
or usage per customer, they are impacted by changes in the number of customers.

Weather. The demand for electricity and natural gas in Delaware is affected by weather conditions. With respect to the electric business, very warm weather
in summer months and, with respect to the electric and natural gas businesses, very cold weather in winter months are referred to as "favorable weather
conditions” because these weather conditions result in increased deliveries of electricity and natural gas. Conversely, mild weather reduces demand. During
the year ended December 31, 2020 compared to the same period in 2019, Operating revenues related to weather decreased primarily due to unfavorable
weather conditions in DPL's Delaware service territory.

Weather. The demand for electricity is affected by weather conditions. With respect to the electric business, very warm weather in summer months and very
cold weather in winter months are referred to as “favorable weather conditions” because these weather conditions result in increased deliveries of electricity.
Conversely, mild weather reduces demand. There was a decrease related to weather for the year ended December 31, 2020 compared to the same period
in 2019 due to the impact of unfavorable weather conditions in ACE's service territory.

partially  offset  by  higher  fully  recoverable  costs.  See  Note  3  —  Regulatory  Matters  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information.

Other Revenue includes rental revenue, service connection fees, and mutual assistance revenues.

Regulatory  Required  Programs  represent  revenues  collected  under  approved  riders  to  recover  costs  incurred  for  regulatory  programs  such  as  energy
efficiency programs, Societal Benefits Charge, Transition Bonds, and BGS procurement and administrative costs. The riders are designed to provide full and
current  cost  recovery  as  well  as  a  return  in  certain  instances.  The  costs  of  these  programs  are  included  in  Purchased  power  expense,  Operating  and
maintenance expense, Depreciation and amortization expense, and Taxes other than income taxes. Customers have the choice to purchase electricity from
competitive electric generation suppliers.

ACE

Customer  choice  programs  do  not  impact  the  volume  of  deliveries,  as  ACE  remains  the  distribution  service  provider  for  all  customers  and  charges  a
regulated rate for distribution service, which is recorded in Operating revenues. For customers that choose to purchase electric generation from competitive
suppliers,  ACE  acts  as  the  billing  agent  and  therefore  does  not  record  Operating  revenues  or  Purchased  power  expense  related  to  the  electricity.  For
customers  that  choose  to  purchase  electric  generation  from  ACE,  ACE  is  permitted  to  recover  the  electricity,  ZEC,  and  REC  procurement  costs  without
mark-up  and  therefore  records  equal  and  offsetting  amounts  in  Operating  revenues  and  Purchased  power  expense  related  to  the  electricity,  ZECs,  and
RECs.

See Note 5 - Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of ACE's revenue disaggregation.

The  increase  of  $1  million  for  the  year  ended  December  31,  2020  compared  to  same  period  in  2019,  in  Purchased  power  expense  is  fully  offset  in

Gain on sale of assets for year ended December 31, 2020 compared to same period in 2019 increased due to the sale of land in the first quarter of 2020.

Effective income tax rates were (57.7)% and 0.0% for the years ended December 31, 2020 and 2019, respectively. The change is primarily related to the
settlement  agreement  of  transmission-related  income  tax  regulatory  liabilities.  See  Note  3  —  Regulatory  Matters  and  Note  14  —  Income  Taxes  of  the
Combined Notes to Consolidated Financial Statements for additional information regarding the components of the change in effective income tax rates.

Liquidity and Capital Resources

All results included throughout the liquidity and capital resources section are presented on a GAAP basis.

The  Registrants’  operating  and  capital  expenditures  requirements  are  provided  by  internally  generated  cash  flows  from  operations,  the  sale  of  certain
receivables, as well as funds from external sources in the capital markets and through bank borrowings. The Registrants’ businesses are capital intensive
and require considerable capital resources. Each of the Registrants annually evaluates its financing plan, dividend practices,

108

Table of Contents

and  credit  line  sizing,  focusing  on  maintaining  its  investment  grade  ratings  while  meeting  its  cash  needs  to  fund  capital  requirements,  retire  debt,  pay
dividends,  fund  pension  and  OPEB  obligations,  and  invest  in  new  and  existing  ventures.  A  broad  spectrum  of  financing  alternatives  beyond  the  core
financing options can be used to meet its needs and fund growth including monetizing assets in the portfolio via project financing, asset sales, and the use of
other financing structures (e.g., joint ventures, minority partners, etc.). Each Registrant’s access to external financing on reasonable terms depends on its
credit  ratings  and  current  overall  capital  market  business  conditions,  including  that  of  the  utility  industry  in  general.  If  these  conditions  deteriorate  to  the
extent that the Registrants no longer have access to the capital markets at reasonable terms, the Registrants have access to credit facilities with aggregate
bank commitments of $10.6 billion. As a result of disruptions in the commercial paper markets due to COVID-19 in March of 2020, Generation borrowed
$1.5 billion on its revolving credit facility to refinance commercial paper. Generation repaid the $1.5 billion borrowed on the revolving credit facility on April 3,
2020 using funds from short-term loans issued in March 2020, cash proceeds from the sale of certain customer accounts receivable, and borrowings from
the  Exelon  intercompany  money  pool.  See  Note  6  —  Accounts  Receivable  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional
information on the sale of customer accounts receivable. See Executive Overview for additional information on COVID-19. The Registrants continue to utilize
their  credit  facilities  to  support  their  commercial  paper  programs,  provide  for  other  short-term  borrowings,  and  to  issue  letters  of  credit.  See  the  “Credit
Matters” section below for additional information. The Registrants expect cash flows to be sufficient to meet operating expenses, financing costs, and capital
expenditure requirements.

The  Registrants  primarily  use  their  capital  resources,  including  cash,  to  fund  capital  requirements,  including  construction  expenditures,  retire  debt,  pay
dividends,  fund  pension  and  OPEB  obligations,  and  invest  in  new  and  existing  ventures.  The  Registrants  spend  a  significant  amount  of  cash  on  capital
improvements  and  construction  projects  that  have  a  long-term  return  on  investment.  Additionally,  the  Utility  Registrants  operate  in  rate-regulated
environments in which the amount of new investment recovery may be delayed or limited and where such recovery takes place over an extended period of
time. See Note 17 — Debt and Credit Agreements of the Combined Notes to Consolidated Financial Statements for additional information of the Registrants’
debt and credit agreements.

Despite disruptions in the financial markets due to COVID-19, the Registrants issued long-term debt of $5.3 billion and were able to successfully complete
their planned long-term debt issuances in 2020.

NRC Minimum Funding Requirements (Exelon and Generation)

NRC  regulations  require  that  licensees  of  nuclear  generating  facilities  demonstrate  reasonable  assurance  that  sufficient  funds  will  be  available  in  certain
minimum amounts to decommission the facility. These NRC minimum funding levels are typically based upon the assumption that decommissioning activities
will  commence  after  the  end  of  the  current  licensed  life  of  each  unit.  If  a  unit  fails  the  NRC  minimum  funding  test,  then  the  plant’s  owners  or  parent
companies  would  be  required  to  take  steps,  such  as  providing  financial  guarantees  through  letters  of  credit  or  parent  company  guarantees  or  making
additional cash contributions to the NDT fund to ensure sufficient funds are available. See Note 10 - Asset Retirement Obligations of the Combined Notes to
Consolidated Financial Statements for additional information.

If a nuclear plant were to early retire there is a risk that it will no longer meet the NRC minimum funding requirements due to the earlier commencement of
decommissioning activities and a shorter time period over which the NDT funds could appreciate in value. A shortfall could require that Generation address
the  shortfall  by,  among  other  things,  obtaining  a  parental  guarantee  for  Generation’s  share  of  the  funding  assurance.  However,  the  amount  of  any
guarantees  or  other  assurance  will  ultimately  depend  on  the  decommissioning  approach,  the  associated  level  of  costs,  and  the  NDT  fund  investment
performance going forward. Within two years after shutting down a plant, Generation must submit a PSDAR to the NRC that includes the planned option for
decommissioning the site. Upon retirement, Dresden will have adequate funding assurance, however, due to the earlier commencement of decommissioning
activities and a shorter time period over which the NDT fund investments could appreciate in value, Byron may no longer meet the NRC minimum funding
requirements  and,  as  a  result,  the  NRC  may  require  additional  financial  assurance  including  possibly  a  parental  guarantee  from  Exelon.  Considering  the
different  approaches  to  decommissioning  available  to  Generation,  the  most  likely  estimates  currently  anticipated  could  require  financial  assurance  for
radiological decommissioning at Byron of up to $90 million.

109

Table of Contents

Upon  issuance  of  any  required  financial  guarantees,  each  site  would  be  able  to  utilize  the  respective  NDT  funds  for  radiological  decommissioning  costs,
which represent the majority of the total expected decommissioning costs. However, under the regulations, the NRC must approve an exemption in order for
Generation to utilize the NDT funds to pay for non-radiological decommissioning costs (i.e. spent fuel management and site restoration costs, if applicable).
If a unit does not receive this exemption, those costs would be borne by Generation without reimbursement from or access to the NDT funds. Accordingly,
based  on  current  projections  of  the  most  likely  decommissioning  approach,  it  is  expected  that  Dresden  would  not  require  supplemental  cash  from
Generation, but some portion of the Byron spent fuel management costs would need to be funded through supplemental cash from Generation. While the
ultimate  amounts  may  vary  and  could  be  offset  by  reimbursement  of  certain  spent  fuel  management  costs  under  the  DOE  settlement  agreement,
decommissioning for Byron may require supplemental cash from Generation of up to $185 million, net of taxes, over a period of 10 years after permanent
shutdown.

As of December 31, 2020, Exelon would not be required to post a parental guarantee for TMI Unit 1 under the SAFSTOR scenario which is the planned
decommissioning option as described in the TMI Unit 1 PSDAR filed by Generation with the NRC on April 5, 2019. On October 16, 2019, the NRC granted
Generation's exemption request to use the TMI Unit 1 NDT funds for spent fuel management costs. An additional exemption request would be required to
allow the funds to be spent on site restoration costs, which are not expected to be incurred in the near term.

Project Financing (Exelon and Generation)

Project financing is used to help mitigate risk of specific generating assets. Project financing is based upon a nonrecourse financial structure, in which project
debt is paid back from the cash generated by the specific asset or portfolio of assets. Borrowings under these agreements are secured by the assets and
equity of each respective project. The lenders do not have recourse against Exelon or Generation in the event of a default. If  a  specific  project  financing
entity does not maintain compliance with its specific debt financing covenants, there could be a requirement to accelerate repayment of the associated debt
or other project-related borrowings earlier than the stated maturity dates. In these instances, if such repayment was not satisfied, or restructured, the lenders
or security holders would generally have rights to foreclose against the project-specific assets and related collateral. The potential requirement to satisfy its
associated debt or other borrowings earlier than otherwise anticipated could lead to impairments due to a higher likelihood of disposing of the respective
project-specific  assets  significantly  before  the  end  of  their  useful  lives.  Additionally,  project  finance  has  credit  facilities.  See  Note  17  —  Debt  and  Credit
Agreements of the Combined Notes to Consolidated Financial Statements for additional information on nonrecourse debt and credit facilities.

Cash Flows from Operating Activities (All Registrants)

Generation’s  cash  flows  from  operating  activities  primarily  result  from  the  sale  of  electric  energy  and  energy-related  products  and  services  to  customers.
Generation’s  future  cash  flows  from  operating  activities  may  be  affected  by  future  demand  for  and  market  prices  of  energy  and  its  ability  to  continue  to
produce and supply power at competitive costs as well as to obtain collections from customers.

The  Utility  Registrants'  cash  flows  from  operating  activities  primarily  result  from  the  transmission  and  distribution  of  electricity  and,  in  the  case  of  PECO,
BGE, and DPL, gas distribution services. The Utility Registrants' distribution services are provided to an established and diverse base of retail customers.
The Utility Registrants' future cash flows may be affected by the economy, weather conditions, future legislative initiatives, future regulatory proceedings with
respect to their rates or operations, and their ability to achieve operating cost reductions.

See  Note  3  —  Regulatory  Matters  and  Note  19  —  Commitments  and  Contingencies  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information of regulatory and legal proceedings and proposed legislation.

Changes  in  the  Registrants'  cash  flows  from  operations  were  generally  consistent  with  changes  in  each  Registrant’s  respective  results  of  operations,  as
adjusted by changes in working capital in the normal course of business, except as discussed below. In addition, significant operating cash flow impacts for
the Registrants for 2020 and 2019 were as follows:

Cash Flows for additional information on income taxes.

Depending  upon  whether  Generation  is  in  a  net  mark-to-market  liability  or  asset  position,  collateral  may  be  required  to  be  posted  with  or
collected from its counterparties. In addition, the collateral posting and collection requirements differ depending on whether the transactions are
on an exchange or in the OTC markets.

During 2020, Exelon and Generation derecognized approximately $1.2 billion of accounts receivable. See Note 6 — Accounts Receivable for
additional information on the sales of customer accounts receivable.

Pension and Other Postretirement Benefits

Management considers various factors when making pension funding decisions, including actuarially determined minimum contribution requirements under
ERISA, contributions required to avoid benefit restrictions and at-risk status as defined by the Pension Protection Act of 2006 (the Act), management of the
pension obligation, and regulatory implications. The Act requires the attainment of certain funding levels to avoid benefit restrictions (such as an inability to
pay lump sums or to accrue benefits prospectively), and at-risk status (which triggers higher minimum contribution requirements and participant notification).
The projected contributions below reflect a funding strategy to make levelized annual contributions with the objective of achieving 100% funded status on an
ABO basis over time. This level funding strategy helps minimize volatility of future period required pension contributions. Based on this funding strategy and
current market conditions, which are subject to change, Exelon’s estimated annual qualified pension contributions will be approximately $500 million in 2021.
Unlike the qualified pension plans, Exelon’s non-qualified pension plans are not funded, given that they are not subject to statutory minimum contribution
requirements.

While OPEB plans are also not subject to statutory minimum contribution requirements, Exelon does fund certain of its plans. For Exelon's funded OPEB
plans, contributions generally equal accounting costs, however, Exelon’s management has historically considered several factors in determining the level of
contributions to its OPEB plans, including liabilities management, levels of benefit claims paid, and regulatory implications (amounts deemed prudent to meet
regulatory expectations and best assure continued rate recovery). The amounts below include benefit payments related to unfunded plans.

To  the  extent  interest  rates  decline  significantly  or  the  pension  and  OPEB  plans  earn  less  than  the  expected  asset  returns,  annual  pension  contribution
requirements in future years could increase. Conversely, to the extent interest rates increase significantly or the pension and OPEB plans earn greater than
the expected asset returns, annual pension and OPEB contribution requirements in future years could decrease. Additionally, expected contributions could
change if Exelon changes its pension or OPEB funding strategy.

Projected capital expenditures and other investments are subject to periodic review and revision to reflect changes in economic conditions and other factors.

Generation

Approximately  48%  of  projected  2021  capital  expenditures  at  Generation  are  for  the  acquisition  of  nuclear  fuel,  with  the  remaining  amounts  primarily
reflecting additions and upgrades to existing generation facilities (including material condition improvements during nuclear refueling outages). Generation
anticipates that it will fund capital expenditures with internally generated funds and borrowings.

Utility Registrants

Projected 2021 capital expenditures at the Utility Registrants are for continuing projects to maintain and improve operations, including enhancing reliability
and adding capacity to the transmission and distribution systems such as the Utility Registrants' construction commitments under PJM’s RTEP.

The Utility Registrants as transmission owners are subject to NERC compliance requirements. NERC provides guidance to transmission owners regarding
assessments  of  transmission  lines.  The  results  of  these  assessments  could  require  the  Utility  Registrants  to  incur  incremental  capital  or  operating  and
maintenance  expenditures  to  ensure  their  transmission  lines  meet  NERC  standards.  In  2010,  NERC  provided  guidance  to  transmission  owners  that
recommended  the  Utility  Registrants  perform  assessments  of  their  transmission  lines.  ComEd,  PECO,  and  BGE  submitted  their  final  bi-annual  reports  to
NERC in January 2014. PECO will be incurring incremental capital expenditures associated with this guidance following the completion of the assessments.
Specific  projects  and  expenditures  are  identified  as  the  assessments  are  completed.  PECO’s  forecasted  2021  capital  expenditures  above  reflect  capital
spending  for  remediation  to  be  completed  through  2021.  ComEd,  BGE,  Pepco,  DPL,  and  ACE  are  complete  with  their  assessments  and  do  not  expect
capital expenditures related to this guidance in 2021.

The Utility Registrants anticipate that they will fund their capital expenditures with a combination of internally generated funds and borrowings and additional
capital contributions from parent.

Long-term  debt,  net,  varies  due  to  debt  issuances  and  redemptions  each  year.  Refer  to  debt  issuances  and  redemptions  tables  below  for
additional information.

Changes in intercompany money pool are driven by short-term borrowing needs. Refer to more information regarding the intercompany money
pool below.

Exelon’s ability to pay dividends on its common stock depends on the receipt of dividends paid by its operating subsidiaries. The payments of
dividends to Exelon by its subsidiaries in turn depend on their results of operations and cash flows and other items affecting retained earnings.
See  Note  19  -  Commitments  and  Contingencies  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  on

Credit Matters (All Registrants)

The  Registrants  fund  liquidity  needs  for  capital  investment,  working  capital,  energy  hedging,  and  other  financial  commitments  through  cash  flows  from
continuing  operations,  public  debt  offerings,  commercial  paper  markets,  and  large,  diversified  credit  facilities.  The  credit  facilities  include  $10.6  billion  in
aggregate total commitments of which $7.7 billion was available to support additional commercial paper as of December 31, 2020, and of which no financial
institution  has  more  than  7%  of  the  aggregate  commitments  for  the  Registrants.  The  Registrants  had  access  to  the  commercial  paper  markets  and  had
availability  under their revolving credit facilities during  2020  to  fund  their  short-term  liquidity  needs,  when  necessary.  The  Registrants  routinely  review  the
sufficiency  of  their  liquidity  position,  including  appropriate  sizing  of  credit  facility  commitments,  by  performing  various  stress  test  scenarios,  such  as
commodity price movements, increases in margin-related transactions, changes in hedging levels, and the impacts of hypothetical credit downgrades. The
Registrants  have  continued  to  closely  monitor  events  in  the  financial  markets  and  the  financial  institutions  associated  with  the  credit  facilities,  including
monitoring credit ratings and outlooks, credit default swap levels, capital raising, and merger activity. See PART I. ITEM 1A. RISK FACTORS for additional
information regarding the effects of uncertainty in the capital and credit markets.

The Registrants believe their cash flow from operating activities, access to credit markets, and their credit facilities provide sufficient liquidity. If Generation
lost its investment grade credit rating as of December 31, 2020, it would have been required to provide incremental collateral of approximately $1.5 billion to
meet collateral obligations for derivatives, non-derivatives, normal purchases and normal sales contracts, and applicable payables and receivables, net of
the contractual right of offset under master netting agreements, which is well within the $4.7 billion of available credit capacity of its revolver.

The following table presents the incremental collateral that each Utility Registrant would have been required to provide in the event each Utility Registrant
lost its investment grade credit rating at December 31, 2020 and available credit facility capacity prior to any incremental collateral at December 31, 2020:

Exelon Credit Facilities

Exelon Corporate, ComEd, and BGE meet their short-term liquidity requirements primarily through the issuance of commercial paper. Generation and PECO
meet their short-term liquidity requirements primarily through the issuance of commercial paper and borrowings from the Exelon intercompany money pool.
Pepco,  DPL,  and  ACE  meet  their  short-term  liquidity  requirements  primarily  through  the  issuance  of  commercial  paper  and  borrowings  from  the  PHI
intercompany  money  pool.  PHI  Corporate  meets  its  short-term  liquidity  requirements  primarily  through  the  issuance  of  short-term  notes  and  the  Exelon
intercompany money pool. The  Registrants  may  use  their  respective  credit  facilities  for  general  corporate  purposes,  including  meeting  short-term  funding
requirements and the issuance of letters of credit.

See  Note  17  —  Debt  and  Credit  Agreements  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  of  the  Registrants’
credit facilities and short term borrowing activity.

Includes approximately $390 million, $205 million, and $184 million owed to unconsolidated affiliates of Exelon, ComEd, and PECO respectively. These special purpose
entities were created for the sole purposes of issuing mandatorily redeemable trust preferred securities of ComEd and PECO. See Note 23 — Variable Interest Entities of
the Combined Notes to Consolidated Financial Statements for additional information regarding the authoritative guidance for VIEs.

Security Ratings

The Registrants’ access to the capital markets, including the commercial paper market, and their respective financing costs in those markets, may depend
on the securities ratings of the entity that is accessing the capital markets.

The  Registrants’  borrowings  are  not  subject  to  default  or  prepayment  as  a  result  of  a  downgrading  of  securities,  although  such  a  downgrading  of  a
Registrant’s securities could increase fees and interest charges under that Registrant’s credit agreements.

As part of the normal course of business, the Registrants enter into contracts that contain express provisions or otherwise permit the Registrants and their
counterparties to demand adequate assurance of future performance when there are reasonable grounds for doing so. In accordance with the contracts and
applicable  contracts  law,  if  the  Registrants  are  downgraded  by  a  credit  rating  agency,  it  is  possible  that  a  counterparty  would  attempt  to  rely  on  such  a
downgrade as a basis for making a demand for adequate assurance of future performance, which could include the posting of collateral. See Note 16 —
Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional information on collateral provisions.

The  credit  ratings  for  Exelon  Corporate,  PECO,  BGE,  PHI,  Pepco,  DPL,  and  ACE  did  not  change  for  the  twelve  months  ended  December  31,  2020.  On
November 4, 2020, S&P revised its assessment of the strategic relationship between Exelon and Generation and subsequently lowered Generation's senior
unsecured debt rating to 'BBB' from 'BBB+'. On July 21, 2020, S&P lowered ComEd's long-term issuer credit rating from 'A-' to a 'BBB+'. S&P also affirmed
the current 'A' rating on ComEd's senior secured debt and 'A-2' short-term rating, which influences long and short-term borrowing cost.

Intercompany Money Pool

To provide an additional short-term borrowing option that will generally be more favorable to the borrowing participants than the cost of external financing,
both Exelon and PHI operate an intercompany money pool. Maximum amounts contributed to and borrowed from the money pool by participant and the net

Exelon, Generation, and the Utility Registrants have a currently effective combined shelf registration statement unlimited in amount, filed with the SEC, that
will expire in August 2022. The ability of each Registrant to sell securities off the shelf registration statement or to access the private placement markets will
depend on a number of factors at the time of the proposed sale, including other required regulatory approvals, as applicable, the current financial condition of
the Registrant, its securities ratings and market conditions.

(a)

Interest payments are estimated based on final maturity dates of debt securities outstanding at December 31, 2020 and do not reflect anticipated future refinancing, early
redemptions, or debt issuances. Variable rate interest obligations are estimated based on rates as of December 31, 2020.

(b) Capacity payments associated with contracted generation lease agreements are net of sublease and capacity offsets of $98 million, $55 million, $44 million, $44 million,

$44 million, and $179 million for 2021, 2022, 2023, 2024, 2025, and thereafter, respectively and $464 million in total.

(c) Purchase  power  obligations  primarily  include  expected  payments  for  REC  purchases  and  capacity  payments  associated  with  contracted  generation  agreements,  which

may be reduced based on plant availability. Expected payments exclude payments on renewable generation contracts that are contingent in nature.

(d) Represents commitments to purchase nuclear fuel, natural gas and related transportation, storage capacity, and services, including those related to CENG.
(e) Represents the future estimated value at December 31, 2020 of the cash flows associated with all contracts, both cancellable and non-cancellable, entered into between
Generation  and  third-parties  for  the  provision  of  services  and  materials,  entered  into  in  the  normal  course  of  business  not  specifically  reflected  elsewhere  in  this  table.

On April 8, 2020, Generation entered into an accounts receivable financing facility with a number of financial institutions and a commercial paper conduit to
sell certain receivables, which expires on April 7, 2021 unless renewed by the mutual consent of the parties in accordance with its terms. The facility allows
Generation to obtain financing at lower cost and diversify its sources of liquidity. See Note 6 — Accounts Receivable of the Combined Notes to Consolidated
Financial Statements for additional information.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The  Registrants are exposed to market risks associated  with  adverse  changes  in  commodity  prices,  counterparty  credit,  interest  rates,  and  equity  prices.
Exelon’s  RMC  approves  risk  management  policies  and  objectives  for  risk  assessment,  control  and  valuation,  counterparty  credit  approval,  and  the
monitoring and reporting of risk exposures. The RMC is chaired by the chief executive officer and includes the chief risk officer, chief strategy officer, chief
executive  officer  of  Exelon  Utilities,  chief  commercial  officer,  chief  financial  officer,  and  chief  executive  officer  of  Constellation.  The  RMC  reports  to  the
Finance and Risk Committee of the Exelon Board of Directors on the scope of the risk management activities.

127

Table of Contents

Commodity Price Risk (All Registrants)

Commodity  price  risk  is  associated  with  price  movements  resulting  from  changes  in  supply  and  demand,  fuel  costs,  market  liquidity,  weather  conditions,
governmental regulatory and environmental policies, and other factors. To the extent the total amount of energy Exelon generates and purchases differs from
the amount of energy it has contracted to sell, Exelon is exposed to market fluctuations in commodity prices. Exelon seeks to mitigate its commodity price
risk through the sale and purchase of electricity, fossil fuel, and other commodities.

Generation

Electricity available from Generation’s owned or contracted generation supply in excess of Generation’s obligations to customers, including portions of the
Utility Registrants' retail load, is sold into the wholesale markets. To reduce commodity price risk caused by market fluctuations, Generation enters into non-
derivative  contracts  as  well  as  derivative  contracts,  including  swaps,  futures,  forwards,  and  options,  with  approved  counterparties  to  hedge  anticipated
exposures. Generation uses derivative instruments as economic hedges to mitigate exposure to fluctuations in commodity prices. Generation expects the
settlement of the majority of its economic hedges will occur during 2021 through 2023.

In  general,  increases  and  decreases  in  forward  market  prices  have  a  positive  and  negative  impact,  respectively,  on  Generation’s  owned  and  contracted
generation positions which have not been hedged. Exelon's hedging program involves the hedging of commodity price risk for Exelon's expected generation,
typically on a ratable basis over three-year periods. As of December 31, 2020, the percentage of expected generation hedged for the Mid-Atlantic, Midwest,
New York, and ERCOT reportable segments is 94%-97% for 2021. The percentage of expected generation hedged is the amount of equivalent sales divided
by  the  expected  generation.  Expected  generation  is  the  volume  of  energy  that  best  represents  our  commodity  position  in  energy  markets  from  owned  or
contracted generation based upon a simulated dispatch model that makes assumptions regarding future market conditions, which are calibrated to market
quotes for power, fuel, load following products, and options. Equivalent sales represent all hedging products, which include economic hedges and certain
non-derivative contracts, including Generation’s sales to ComEd, PECO, BGE, Pepco, DPL, and ACE to serve their retail load.

A portion of Generation’s hedging strategy may be accomplished with fuel products based on assumed correlations between power and fuel prices, which
routinely  change  in  the  market.  Market  price  risk  exposure  is  the  risk  of  a  change  in  the  value  of  unhedged  positions.  The  forecasted  market  price  risk
exposure  for  Generation’s  entire  economic  hedge  portfolio  associated  with  a  $5  reduction  in  the  annual  average  around-the-clock  energy  price  based  on
December 31, 2020 market conditions and hedged position would be a decrease in pre-tax net income of approximately $15 million for 2021. Power price
sensitivities  are  derived  by  adjusting  power  price  assumptions  while  keeping  all  other  price  inputs  constant.  Generation  actively  manages  its  portfolio  to
mitigate market price risk exposure for its unhedged position. Actual results could differ depending on the specific timing of, and markets affected by, price
changes,  as  well  as  future  changes  in  Generation’s  portfolio.  See  Note  16  —  Derivative  Financial  Instruments  of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information.

Fuel Procurement

Generation  procures  natural  gas  through  long-term  and  short-term  contracts,  and  spot-market  purchases.  Nuclear  fuel  assemblies  are  obtained
predominantly through long-term uranium concentrate supply contracts, contracted conversion services, contracted enrichment services, or a combination
thereof,  and  contracted  fuel  fabrication  services.  The  supply  markets  for  uranium  concentrates  and  certain  nuclear  fuel  services  are  subject  to  price
fluctuations and availability restrictions. Supply market conditions may make Generation’s procurement contracts subject to credit risk related to the potential
non-performance  of  counterparties  to  deliver  the  contracted  commodity  or  service  at  the  contracted  prices.  Approximately  60%  of  Generation’s  uranium
concentrate requirements from 2021 through 2025 are supplied by three suppliers. In the event of non-performance by these or other suppliers, Generation
believes that replacement uranium concentrates can be obtained, although at prices that may be unfavorable when compared to the prices under the current
supply agreements. Non-performance by these counterparties could have a material adverse impact on Exelon’s and Generation’s financial statements.

Utility Registrants

ComEd entered into 20-year floating-to-fixed renewable energy swap contracts beginning in June 2012, which are considered an economic hedge and have
changes in fair value recorded to an offsetting regulatory asset or liability. ComEd has block energy contracts to procure electric supply that are executed
through a competitive procurement process, which are considered derivatives and qualify for NPNS, and as a result are accounted for on an accrual basis of
accounting. PECO, BGE, Pepco, DPL, and ACE  have  contracts  to  procure  electric  supply  that  are  executed  through  a  competitive  procurement  process.
BGE, Pepco, DPL, and ACE have certain full requirements contracts, which are considered derivatives and qualify for NPNS, and as a result are accounted
for on an accrual basis of accounting. Other full requirements contracts are not derivatives.

PECO, BGE, and DPL also have executed derivative natural gas contracts, which either qualify for NPNS or have no mark-to-market balances because the
derivatives are index priced, to hedge their long-term price risk in the natural gas market. The hedging programs for natural gas procurement have no direct
impact on their financial statements. PECO, BGE, Pepco, DPL, and ACE do not execute derivatives for speculative or proprietary trading purposes.

For additional information on these contracts, see Note 3 — Regulatory Matters and Note 16 — Derivative Financial Instruments of the Combined Notes to
Consolidated Financial Statements.

Trading and Non-Trading Marketing Activities

The following table detailing Exelon’s, Generation’s, and ComEd’s trading and non-trading marketing activities are included to address the recommended
disclosures by the energy industry’s Committee of Chief Risk Officers (CCRO).

The  following  table  provides  detail  on  changes  in  Exelon’s,  Generation’s,  and  ComEd’s  commodity  mark-to-market  net  asset  or  liability  balance  sheet
position from December 31, 2018 to December 31, 2020. It indicates the drivers behind changes in the balance sheet amounts. This table incorporates the
mark-to-market  activities  that  are  immediately  recorded  in  earnings.  This  table  excludes  all  NPNS  contracts  and  does  not  segregate  proprietary  trading
activity.  See  Note  16  —  Derivative  Financial  Instruments  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  on  the
balance sheet classification of the mark-to-market energy contract net assets (liabilities) recorded as of December 31, 2020 and 2019.

Fair Values

The following tables present maturity and source of fair value for Exelon, Generation, and ComEd mark-to-market commodity contract net assets (liabilities).
The tables provide two fundamental pieces of information. First, the tables provide the source of fair value used in determining the carrying amount of the
Registrants’  total  mark-to-market  net  assets  (liabilities),  net  of  allocated  collateral.  Second,  the  tables  show  the  maturity,  by  year,  of  the  Registrants’
commodity  contract  net  assets  (liabilities),  net  of  allocated  collateral,  giving  an  indication  of  when  these  mark-to-market  amounts  will  settle  and  either
generate  or  require  cash.  See  Note  18  —  Fair  Value  of  Financial  Assets  and  Liabilities  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information regarding fair value measurements and the fair value hierarchy.

Credit Risk (All Registrants)

The Registrants would be exposed to credit-related losses in the event of non-performance by counterparties that execute derivative instruments. The credit
exposure  of  derivative  contracts,  before  collateral,  is  represented  by  the  fair  value  of  contracts  at  the  reporting  date.  See  Note  16—Derivative  Financial
Instruments of the Combined Notes to Consolidated Financial Statements for a detailed discussion of credit risk.

The Utility Registrants

Credit risk for the Utility Registrants is governed by credit and collection policies, which are aligned with state regulatory requirements. The Utility Registrants
are  currently  obligated  to  provide  service  to  all  electric  customers  within  their  franchised  territories.  The  Utility  Registrants  record  an  allowance  for  credit
losses on customer receivables, based upon historical loss experience, current conditions, and forward-looking risk factors, to provide for the potential loss
from  nonpayment  by  these  customers.  The  Utility  Registrants  will  monitor  nonpayment  from  customers  and  will  make  any  necessary  adjustments  to  the
allowance  for  credit  losses  on  customer  receivables.  See  Note  1  —  Significant  Accounting  Policies  of  the  Combined  Notes  to  Consolidated  Financial
Statements  for  the  allowance  for  credit  losses  policy.  The  Utility  Registrants  did  not  have  any  customers  representing  over  10%  of  their  revenues  as  of
December 31, 2020. See Note 3 — Regulatory Matters of the

132

Table of Contents

Combined Notes to Consolidated Financial Statements for additional information regarding the regulatory recovery of credit losses on customer accounts
receivable.

As of December 31, 2020, the Utility Registrants net credit exposure to suppliers was immaterial. See Note 16 — Derivative Financial Instruments of the
Combined Notes to Consolidated Financial Statements.

Credit-Risk-Related Contingent Features (All Registrants)

Generation

As part of the normal course of business, Generation routinely enters into physical or financial contracts for the sale and purchase of electricity, natural gas,
and  other  commodities.  In  accordance  with  the  contracts  and  applicable  law,  if  Generation  is  downgraded  by  a  credit  rating  agency,  especially  if  such
downgrade  is  to  a  level  below  investment  grade,  it  is  possible  that  a  counterparty  would  attempt  to  rely  on  such  a  downgrade  as  a  basis  for  making  a
demand for adequate assurance of future performance. Depending on Generation’s net position with a counterparty, the demand could be for the posting of
collateral.  In  the  absence  of  expressly  agreed-to  provisions  that  specify  the  collateral  that  must  be  provided,  collateral  requested  will  be  a  function  of  the
facts and circumstances of the situation at the time of the demand. See Note 16 — Derivative Financial Instruments of the Combined Notes to Consolidated
Financial Statements for additional information regarding collateral requirements and Note 19 — Commitments and Contingencies of the Combined Notes to
Consolidated Financial Statements for additional information regarding the letters of credit supporting the cash collateral.

Generation transacts output through bilateral contracts. The bilateral contracts are subject to credit risk, which relates to the ability of counterparties to meet
their contractual payment obligations. Any failure to collect these payments from counterparties could have a material impact on Exelon’s and Generation’s
financial statements. As market prices rise above or fall below contracted price levels, Generation is required to post collateral with purchasers; as market
prices fall below contracted price levels, counterparties are required to post collateral with Generation. To post collateral, Generation depends on access to
bank  credit  facilities,  which  serve  as  liquidity  sources  to  fund  collateral  requirements.  See  ITEM  7.  Liquidity  and  Capital  Resources  —  Credit  Matters  —
Exelon Credit Facilities for additional information.

The Utility Registrants

As of December 31, 2020, the Utility Registrants were not required to post collateral under their energy and/or natural gas procurement contracts. See Note
3  —  Regulatory  Matters  and  Note  16  —  Derivative  Financial  Instruments  of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional
information.

RTOs and ISOs (All Registrants)

All Registrants participate in all, or some, of the established, wholesale spot energy markets that are administered by PJM, ISO-NE, NYISO, CAISO, MISO,
SPP,  AESO,  OIESO,  and  ERCOT.  ERCOT  is  not  subject  to  regulation  by  FERC  but  performs  a  similar  function  in  Texas  to  that  performed  by  RTOs  in
markets regulated by FERC. In these areas, power is traded through bilateral agreements between buyers and sellers and on the spot energy markets that
are administered by the RTOs or ISOs, as applicable. In areas where there is no spot energy market, electricity is purchased and sold solely through bilateral
agreements. For sales into the spot markets administered by an RTO or ISO, the RTO or ISO maintains financial assurance policies that are established and
enforced by those administrators. The credit policies of the RTOs and ISOs may, under certain circumstances, require that losses arising from the default of
one member on spot energy market transactions be shared by the remaining participants. Non-performance or non-payment by a major counterparty could
result in a material adverse impact on the Registrants’ financial statements.

Exchange Traded Transactions (Exelon, Generation, PHI, and DPL)

Generation enters into commodity transactions on NYMEX, ICE, NASDAQ, NGX, and the Nodal exchange ("the Exchanges"). DPL enters into commodity
transactions on ICE. The Exchange clearinghouses act as the counterparty to each trade. Transactions on the Exchanges must adhere to comprehensive
collateral and margining requirements. As a result, transactions on Exchanges are significantly collateralized and have limited counterparty credit risk.

133

Table of Contents

Interest Rate and Foreign Exchange Risk (Exelon and Generation)

Exelon  and  Generation  use  a  combination  of  fixed-rate  and  variable-rate  debt  to  manage  interest  rate  exposure.  Exelon  and  Generation  may  also  utilize
interest rate swaps to manage their interest rate exposure. A hypothetical 50 basis point increase in the interest rates associated with unhedged variable-
rate  debt  (excluding  Commercial  Paper)  and  fixed-to-floating  swaps  would  result  in  approximately  a  $2  million  decrease  in  Exelon  pre-tax  income  for  the
year ended December 31, 2020. To manage foreign exchange rate exposure associated with international energy purchases in currencies other than U.S.
dollars, Generation utilizes foreign currency derivatives, which are typically designated as economic hedges. See Note 16—Derivative Financial Instruments
of the Combined Notes to Consolidated Financial Statements for additional information.

Equity Price Risk (Exelon and Generation)

Exelon and Generation maintain trust funds, as required by the NRC, to fund certain costs of decommissioning its nuclear plants. As of December 31, 2020,
Generation’s NDT funds are reflected at fair value in its Consolidated Balance Sheets. The mix of securities in the trust funds is designed to provide returns
to be used to fund decommissioning and to compensate Generation for inflationary increases in decommissioning costs; however, the equity securities in the
trust funds are exposed to price fluctuations in equity markets, and the value of fixed-rate, fixed-income securities are exposed to changes in interest rates.
Generation actively monitors the investment performance of the trust funds and periodically reviews asset allocation in accordance with Generation’s NDT
fund investment policy. A hypothetical 25 basis points increase in interest rates and 10% decrease in equity prices would result in a $851 million reduction in
the fair value of the trust assets. This calculation holds all other variables constant and assumes only the discussed changes in interest rates and equity
prices.  See  Liquidity  and  Capital  Resources  section  of  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND
RESULTS OF OPERATIONS for additional information of equity price risk as a result of the current capital and credit market conditions.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Generation

General

Generation’s  integrated  business  consists  of  the  generation,  physical  delivery,  and  marketing  of  power  across  multiple  geographical  regions  through  its
customer-facing  business,  Constellation,  which  sells  electricity  and  natural  gas  to  both  wholesale  and  retail  customers.  Generation  also  sells  renewable
energy and other energy-related products and services. Generation has five reportable segments consisting of the Mid-Atlantic, Midwest, New York, ERCOT,
and Other Power Regions. These segments are discussed in further detail in ITEM 1. BUSINESS — Exelon Generation Company, LLC of this Form 10-K.

Executive Overview

A  discussion  of  items  pertinent  to  Generation’s  executive  overview  is  set  forth  under  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS — Exelon Corporation — Executive Overview of this Form 10-K.

Results of Operations

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019

A  discussion  of  Generation’s  results  of  operations  for  2020  compared  to  2019  is  set  forth  under  Results  of  Operations—Generation  in  EXELON
CORPORATION — Results of Operations of this Form 10-K.

Liquidity and Capital Resources

Generation’s  business  is  capital  intensive  and  requires  considerable  capital  resources.  Generation’s  capital  resources  are  primarily  provided  by  internally
generated  cash  flows  from  operations  and,  to  the  extent  necessary,  external  financing,  including  the  issuance  of  long-term  debt,  commercial  paper,
participation  in  the  intercompany  money  pool,  or  capital  contributions  from  Exelon.  Generation’s  access  to  external  financing  at  reasonable  terms  is
dependent  on  its  credit  ratings  and  general  business  conditions,  as  well  as  that  of  the  utility  industry  in  general.  If  these  conditions  deteriorate  to  where
Generation no longer has access to the capital markets at reasonable terms, Generation has credit facilities in the aggregate of $5.3 billion that currently
support its commercial paper program and issuances of letters of credit. 

See  EXELON  CORPORATION  —  Liquidity  and  Capital  Resources  and  Note  17  —  Debt  and  Credit  Agreements  of  the  Combined  Notes  to  Consolidated
Financial Statements of this Form 10-K for additional information.

Capital resources are used primarily to fund Generation’s capital requirements, including construction expenditures, retire debt, pay dividends, fund pension
and OPEB obligations, and invest in new and existing ventures. Generation spends a significant amount of cash on capital improvements and construction
projects that have a long-term return on investment.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management’s Report on Internal Control Over Financial Reporting

The management of Exelon Corporation (Exelon) is responsible for establishing and maintaining adequate internal control over financial reporting, as such
term is defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of
compliance with the policies or procedures may deteriorate.

Exelon’s  management  conducted  an  assessment  of  the  effectiveness  of  Exelon’s  internal  control  over  financial  reporting  as  of  December  31,  2020.  In
making  this  assessment,  management  used  the  criteria  in  Internal  Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission. Based on this assessment, Exelon’s management concluded that, as of December 31, 2020, Exelon’s internal
control over financial reporting was effective.

The  effectiveness  of  Exelon’s  internal  control  over  financial  reporting  as  of  December  31,  2020,  has  been  audited  by  PricewaterhouseCoopers  LLP,  an
independent registered public accounting firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Exelon Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the consolidated financial statements, including the related notes, as listed in the index appearing under Item 15(a)(1)(i), and the financial
statement schedules listed in the index appearing under Item 15(a)(1)(ii), of Exelon Corporation and its subsidiaries (the “Company”) (collectively referred to
as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2020, based on
criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in
conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and
for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial
Reporting appearing under Item 8. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's
internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective
internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,
evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing
such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over
financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company

160

Table of Contents

are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were
communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated
financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter
in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below,
providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Annual Nuclear Decommissioning Asset Retirement Obligations (ARO) Assessment

As described in Notes 1 and 10 to the consolidated financial statements, the Company has a legal obligation to decommission its nuclear generation stations
following the expiration of their operating licenses. To estimate its decommissioning obligation related to its nuclear generating stations for financial
accounting and reporting purposes, management uses a probability-weighted cash flow model, which on a unit-by-unit basis, considers multiple scenarios
that include significant estimates and assumptions such as decommissioning cost studies, cost escalation rates, probabilistic cash flow models and discount
rates. Management updates its ARO annually unless circumstances warrant more frequent updates, based on its review of updated cost studies and its
annual evaluation of cost escalation factors and probabilities assigned to various scenarios. As of December 31, 2020, the nuclear decommissioning ARO
was approximately $11.9 billion.

The principal considerations for our determination that performing procedures relating to the Company’s annual ARO assessment is a critical audit matter
are the significant judgment by management when estimating its decommissioning obligation; this in turn led to a high degree of auditor judgment,
subjectivity, and effort in performing procedures and evaluating the reasonableness of management’s cash flow model and significant assumptions related to
decommissioning cost studies. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls relating to management’s development of the inputs, assumptions, and
model used in management’s ARO assessment. These procedures also included, among others, testing management’s process for developing the ARO
estimates by evaluating the appropriateness of the cash flow model, testing the completeness and accuracy of data used by management, and evaluating
the reasonableness of management’s significant assumptions related to decommissioning cost studies. Professionals with specialized skill and knowledge
were used to assist in evaluating the results of decommissioning cost studies.

Impairment Assessment of Long-Lived Generation Assets

As described in Notes 1 and 12 to the consolidated financial statements, the Company evaluates the carrying value of long-lived assets or asset groups for
recoverability whenever events or changes in circumstances indicate that the carrying value of those assets may not be recoverable. Indicators of
impairment may include a deteriorating business climate, including, but not limited to, declines in energy prices, condition of the asset, or plans to dispose of
a long-lived asset significantly before the end of its useful life. Management determines if long-lived assets and asset groups are impaired by comparing the
undiscounted expected future cash flows to the carrying value. When the undiscounted cash flow analysis indicates a long-lived asset or asset group is not
recoverable, the amount of the impairment loss is determined by measuring the excess of the carrying amount of the long-lived asset or asset group over its
fair value. The expected future cash flows include significant unobservable inputs including revenue and generation forecasts, projected capital and
maintenance expenditures and discount rates. As of December 31, 2020, the total carrying value of long-lived generation assets subject to this evaluation
was approximately $22.2 billion.

161

Table of Contents

The principal considerations for our determination that performing procedures relating to the Company’s impairment assessment of long-lived generation
assets is a critical audit matter are the significant judgment by management in assessing the recoverability of these asset groups; this in turn led to a high
degree of auditor judgment, subjectivity and effort in performing procedures and evaluating the reasonableness of management’s significant assumptions
related to revenue and generation forecasts. In addition, the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls relating to management’s development of the inputs, assumptions, and
model used to estimate the recoverability and fair value of the Company’s long-lived generation asset groups. These procedures also included, among
others, testing management’s process for developing expected future cash flows for long-lived generation asset groups by evaluating the appropriateness of
the future cash flow model, testing the completeness and accuracy of the data used by management, and evaluating the reasonableness of management’s
significant assumptions related to revenue and generation forecasts. Professionals with specialized skill and knowledge were used to assist in evaluating the
reasonableness of revenue forecasts.

Accounting for the Effects of Rate Regulation

As described in Notes 1 and 3 to the consolidated financial statements, the Company applies the authoritative guidance for accounting for certain types of
regulation, which requires management to record in their consolidated financial statements the effects of cost-based rate regulation for entities with regulated
operations that meet the following criteria, (i) rates are established or approved by a third-party regulator; (ii) rates are designed to recover the entity’s cost of
providing services or products; and (iii) there is a reasonable expectation that rates designed to recover costs can be charged to and collected from
customers. The Company accounts for its regulated operations in accordance with regulatory and legislative guidance from the regulatory authorities having
jurisdiction under state public utility laws and the FERC under various Federal laws. Upon updates in material regulatory and legislative proceedings, where
applicable, management will record new regulatory assets or liabilities and will assess whether it is probable that its currently recorded regulatory assets and
liabilities will be recovered and settled, respectively, in future rates. As of December 31, 2020, there were approximately $10.0 billion of regulatory assets
and approximately $10.1 billion of regulatory liabilities.

The principal considerations for our determination that performing procedures relating to management’s accounting for the effects of rate regulation is a
critical audit matter are the high degree of audit effort to assess the impact of regulation on accounting for regulatory assets and liabilities and to evaluate the
complex audit evidence related to whether the regulatory assets and liabilities will be recovered and settled.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls relating to accounting for regulatory matters and evaluation of existing
regulatory assets and liabilities. These procedures also included, among others, obtaining the Company’s correspondence with regulators, evaluating the
reasonableness of management’s judgments regarding regulatory guidance and proceedings and the related accounting implications, and calculating
regulatory assets and liabilities based on provisions outlined in rate orders and other correspondence with regulators.

the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required
to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the financial statements and (ii) involved our
especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial
statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on
the accounts or disclosures to which it relates.

Accounting for the Effects of Rate Regulation

As described in Notes 1 and 3 to the financial statements, the Company applies the authoritative guidance for accounting for certain types of regulation,
which requires management to record in their financial statements the effects of cost-based rate regulation for entities with regulated operations that meet
the following criteria, (i) rates are established or approved by a third-party regulator; (ii) rates are designed to recover the entity’s cost of providing services or
products; and (iii) there is a reasonable expectation that rates designed to recover costs can be charged to and collected from customers. The Company
accounts for its regulated operations in

169

Table of Contents

accordance with regulatory and legislative guidance from the regulatory authorities having jurisdiction under state public utility laws and the FERC under
various Federal laws. Upon updates in material regulatory and legislative proceedings, where applicable, management will record new regulatory assets or
liabilities and will assess whether it is probable that its currently recorded regulatory assets and liabilities will be recovered and settled, respectively, in future
rates. As of December 31, 2020, there were approximately $649 million of regulatory assets and approximately $1,139 million of regulatory liabilities.

The principal considerations for our determination that performing procedures relating to management’s accounting for the effects of rate regulation is a
critical audit matter are the high degree of audit effort to assess the impact of regulation on accounting for regulatory assets and liabilities and to evaluate the
complex audit evidence related to whether the regulatory assets and liabilities will be recovered and settled.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial
statements. These procedures included testing the effectiveness of controls relating to accounting for regulatory matters and evaluation of existing regulatory
assets and liabilities. These procedures also included, among others, obtaining the Company’s correspondence with regulators, evaluating the
reasonableness of management’s judgments regarding regulatory guidance and proceedings and the related accounting implications, and calculating
regulatory assets and liabilities based on provisions outlined in rate orders and other correspondence with regulators.

We have audited the consolidated financial statements, including the related notes, as listed in the index appearing under Item 15(a)(6)(i), and the financial
statement schedule listed in the index appearing under Item 15(a)(6)(ii), of Pepco Holdings LLC and its subsidiaries (the “Company”) (collectively referred to
as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position
of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2020 in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board

applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to
error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our
audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the
effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

next  to  each  corresponding  disclosure.  When  appropriate,  the  Registrants  are  named  specifically  for  their  related  activities  and  disclosures.  Each  of  the
Registrant’s Consolidated Financial Statements includes the accounts of its subsidiaries. All intercompany transactions have been eliminated.

Through its business services subsidiary, BSC, Exelon provides its subsidiaries with a variety of support services at cost, including legal, human resources,
financial,  information  technology,  and  supply  management  services.  PHI  also  has  a  business  services  subsidiary,  PHISCO,  which  provides  a  variety  of
support services at cost, including legal, accounting, engineering, customer operations, distribution and transmission planning, asset management, system
operations,  and  power  procurement,  to  PHI  operating  companies.  The  costs  of  BSC  and  PHISCO  are  directly  charged  or  allocated  to  the  applicable
subsidiaries. The results of Exelon’s corporate operations are presented as “Other” within the consolidated financial statements and include intercompany
eliminations unless otherwise disclosed.

Exelon owns 100% of Generation, PECO, BGE, and PHI and more than 99% of ComEd. PHI owns 100% of Pepco, DPL, and ACE. Generation owns 100%
of its significant consolidated subsidiaries, either directly or

indirectly,  except  for  certain  consolidated  VIEs,  including  CENG  and  EGRP,  of  which  Generation  holds  a  50.01%  and  51%  interest,  respectively.  The
remaining interests in these consolidated VIEs are included in noncontrolling interests on Exelon’s and Generation’s Consolidated Balance Sheets. See Note
23 — Variable Interest Entities for additional information of Exelon’s and Generation’s consolidated VIEs.

The  Registrants  consolidate  the  accounts  of  entities  in  which  a  Registrant  has  a  controlling  financial  interest,  after  the  elimination  of  intercompany
transactions.  Where  the  Registrants  do  not  have  a  controlling  financial  interest  in  an  entity,  proportionate  consolidation,  equity  method  accounting,  or
accounting for investments in equity securities with or without readily determinable fair value is applied. The Registrants apply proportionate consolidation
when they have an undivided interest in an asset and are proportionately liable for their share of each liability associated with the asset. The Registrants
proportionately consolidate their undivided ownership interests in jointly owned electric plants and transmission facilities. Under proportionate consolidation,
the Registrants separately record their proportionate share of the assets, liabilities, revenues, and expenses related to the undivided interest in the asset.
The  Registrants  apply  equity  method  accounting  when  they  have  significant  influence  over  an  investee  through  an  ownership  in  common  stock,  which
generally  approximates  a  20%  to  50%  voting  interest.  The  Registrants  apply  equity  method  accounting  to  certain  investments  and  joint  ventures.  Under
equity method accounting, the Registrants report their interest in the entity as an investment and the Registrants’ percentage share of the earnings from the
entity  as  single  line  items  in  their  financial  statements.  The  Registrants  use  accounting  for  investments  in  equity  securities  with  or  without  readily
determinable  fair  values  if  they  lack  significant  influence,  which  generally  results  when  they  hold  less  than  20%  of  the  common  stock  of  an  entity.  Under
accounting for investments in equity securities with readily determinable fair values, the Registrants report their investment values based on quoted prices in
active markets and realized and unrealized gains and losses are included in earnings. Under accounting for investments in equity securities without readily
determinable  fair  values,  the  Registrants  report  their  investments  at  cost  adjusted  for  changes  from  observable  transactions  for  identical  or  similar
investments of the same issuer, less impairment, and changes in measurement are reported in earnings.

The accompanying consolidated financial statements have been prepared in accordance with GAAP for annual financial statements and in accordance with
the instructions to Form 10-K and Regulation S-X promulgated by the SEC.

COVID-19 (All Registrants)

The Registrants have taken steps to mitigate the potential risks posed by the global outbreak (pandemic) of the 2019 novel coronavirus (COVID-19). The
Registrants  provide  a  critical  service  to  their  customers  and  have  taken  measures  to  keep  employees  who  operate  the  business  safe  and  minimize
unnecessary risk of exposure to the virus, including extra precautions for employees who work in the field. The Registrants have implemented work from
home policies where appropriate and imposed travel limitations on employees. In addition, the Registrants have updated their existing business continuity
plans.

Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities
as  of  the  date  of  the  financial  statements  and  accompanying  notes,  and  the  amounts  of  revenues  and  expenses  reported  during  the  periods  covered  by
those  financial  statements  and  accompanying  notes.  Management  assessed  certain  accounting  matters  that  require  consideration  of  forecasted  financial
information, including, but not limited to, the Registrants' allowance for credit losses and the carrying value of goodwill and other long-lived assets, in context
with the information reasonably available to the Registrants and the unknown future impacts of COVID-19 as of December 31, 2020 and through the date of
this  report.  The  Registrants'  future  assessment  of  their  current  expectations  of  the  magnitude  and  duration  of  COVID-19,  as  well  as  other  factors,  could
result in material impacts to their consolidated financial statements in future reporting periods.

Use of Estimates (All Registrants)

The preparation of financial statements of each of the Registrants in conformity with GAAP requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes. Areas in which significant estimates have been made include, but are not
limited to, the accounting for nuclear decommissioning costs and other AROs, pension and OPEB, inventory reserves, allowance for credit losses, goodwill
and asset impairment assessments, derivative instruments, unamortized

225

energy contracts, fixed asset depreciation, environmental costs and other loss contingencies, taxes, and unbilled energy revenues. Actual results could differ
from those estimates.

Accounting for the Effects of Regulation (Exelon and the Utility Registrants)

For their regulated electric and gas operations, Exelon and the Utility Registrants reflect the effects of cost-based rate regulation in their financial statements,
which  is  required  for  entities  with  regulated  operations  that  meet  the  following  criteria:  1)  rates  are  established  or  approved  by  a  third-party  regulator;
(2) rates are designed to recover the entities’ cost of providing services or products; and (3) there is a reasonable expectation that rates designed to recover
costs  can  be  charged  to  and  collected  from  customers.  Exelon  and  the  Utility  Registrants  account  for  their  regulated  operations  in  accordance  with
regulatory  and  legislative  guidance  from  the  regulatory  authorities  having  jurisdiction,  principally  the  ICC,  PAPUC,  MDPSC,  DCPSC,  DPSC,  and  NJBPU,
under state public utility laws and the FERC under various Federal laws. Regulatory assets and liabilities are amortized and the related expense or revenue
is recognized in the Consolidated Statements of Operations consistent with the recovery or refund included in customer rates. Exelon's regulatory assets
and liabilities as of the balance sheet date are probable of being recovered or settled in future rates. If a separable portion of the Registrants' business was
no  longer  able  to  meet  the  criteria  discussed  above,  the  affected  entities  would  be  required  to  eliminate  from  their  consolidated  financial  statements  the
effects  of  regulation  for  that  portion,  which  could  have  a  material  impact  on  their  financial  statements.  See  Note  3  —  Regulatory  Matters  for  additional
information.

With the exception of income tax-related regulatory assets and liabilities, Exelon and the Utility Registrants classify regulatory assets and liabilities with a
recovery  or  settlement  period  greater  than  one  year  as  both  current  and  non-current  in  their  Consolidated  Balance  Sheets,  with  the  current  portion
representing the amount expected to be recovered from or refunded to customers over the next twelve-month period as of the balance sheet date.  Income
tax-related regulatory assets and liabilities are classified entirely as non-current in Exelon's and the Utility Registrants’ Consolidated Balance Sheets to align
with the classification of the related deferred income tax balances.

Exelon  and  the  Utility  Registrants  treat  the  impacts  of  a  final  rate  order  received  after  the  balance  sheet  date  but  prior  to  the  issuance  of  the  financial
statements as a non-recognized subsequent event, as the receipt of a final rate order is a separate and distinct event that has future impacts on the parties
affected by the order.

Revenues (All Registrants)

Operating Revenues. The Registrants’ operating revenues generally consist of revenues from contracts with customers involving the sale and delivery of
energy commodities and related products and services, utility revenues from ARP, and realized and unrealized revenues recognized under mark-to-market
energy  commodity  derivative  contracts.  The  Registrants  recognize  revenue  from  contracts  with  customers  to  depict  the  transfer  of  goods  or  services  to
customers in an amount that the entities expect to be entitled to in exchange for those goods or services. Generation’s primary sources of revenue include
competitive  sales  of  power,  natural  gas,  and  other  energy-related  products  and  services.  The  Utility  Registrants’  primary  sources  of  revenue  include
regulated electric and natural gas tariff sales, distribution, and transmission services. At the end of each month, the Registrants accrue an estimate for the
unbilled amount of energy delivered or services provided to customers.

ComEd  records  ARP  revenue  for  its  best  estimate  of  the  electric  distribution,  energy  efficiency,  and  transmission  revenue  impacts  resulting  from  future
changes in rates that ComEd believes are probable of approval by the ICC and FERC in accordance with its formula rate mechanisms. BGE, Pepco, and
DPL record ARP revenue for their best estimate of the electric and natural gas distribution revenue impacts resulting from future changes in rates that they
believe are probable of approval by the MDPSC and/or DCPSC in accordance with their revenue decoupling mechanisms. PECO, BGE, Pepco, DPL, and
ACE record ARP revenue for their best estimate of the transmission revenue impacts resulting from future changes in rates that they believe are probable of
approval by FERC in accordance with their formula rate mechanisms. See Note 3 — Regulatory Matters for additional information.

Option Contracts, Swaps, and Commodity Derivatives. Certain option contracts and swap arrangements that meet the definition of derivative instruments
are recorded at fair value with subsequent changes in fair value recognized as revenue or expense. The classification of revenue or expense is based on the
intent  of  the  transaction.  To  the  extent  a  Utility  Registrant  receives  full  cost  recovery  for  energy  procurement  and  related  costs  from  retail  customers,  it
records the fair value of its energy swap contracts with unaffiliated suppliers as well as

226

an  offsetting  regulatory  asset  or  liability  in  its  Consolidated  Balance  Sheets.  See  Note  3  —  Regulatory  Matters  and  Note  16  —  Derivative  Financial
Instruments for additional information.

Taxes Directly Imposed on Revenue-Producing Transactions. The  Registrants  collect  certain  taxes  from  customers  such  as  sales  and  gross  receipts
taxes, along with other taxes, surcharges, and fees, that are levied by state or local governments on the sale or distribution of electricity and gas. Some of
these taxes are imposed on the customer, but paid by the Registrants, while others are imposed on the Registrants. Where these taxes are imposed on the
customer, such as sales taxes, they are reported on a net basis with no impact to the Consolidated Statements of Operations and Comprehensive Income.
However, where these taxes are imposed on the Registrants, such as gross receipts taxes or other surcharges or fees, they are reported on a gross basis.
Accordingly,  revenues  are  recognized  for  the  taxes  collected  from  customers  along  with  an  offsetting  expense.  See Note  24  —  Supplemental  Financial
Information for Generation’s and the Utility Registrants' utility taxes that are presented on a gross basis.

Leases (All Registrants)

The Registrants adopted new accounting guidance issued by the FASB related to leases as of January 1, 2019. The Registrants recognize a ROU asset and
lease liability for operating and finance leases with a term of greater than one year. Operating lease ROU assets are included in Other deferred debits and
other assets and operating lease liabilities are included in Other current liabilities and Other deferred credits and other liabilities on the Consolidated Balance
Sheets. Finance lease ROU assets are included in Plant, property, and equipment, net and finance lease liabilities are included in Long-term debt due within
one year and Long-term debt on the Consolidated Balance Sheets. The ROU asset is measured as the sum of (1) the present value of all remaining fixed
and in-substance fixed payments using each Registrant’s incremental borrowing rate, (2) any lease payments made at or before the commencement date
(less any lease incentives received), and (3) any initial direct costs incurred. The lease liability is measured the same as the ROU asset, but excludes any
payments  made  before  the  commencement  date  and  initial  direct  costs  incurred.  Lease  terms  include  options  to  extend  or  terminate  the  lease  if  it  is
reasonably certain they will be exercised. The Registrants include non-lease components for most asset classes, which are service-related costs that are not
integral to the use of the asset, in the measurement of the ROU asset and lease liability.

Expense for operating leases and leases with a term of one year or less is recognized on a straight-line basis over the term of the lease, unless another
systematic and rational basis is more representative of the derivation of benefit from use of the leased property. Variable lease payments are recognized in
the period in which the related obligation is incurred and consist primarily of payments for purchases of electricity under contracted generation and are based
on the electricity produced by those generating assets. Operating lease expense and variable lease payments are recorded to Purchased power and fuel
expense for contracted generation or Operating and maintenance expense for all other lease agreements on the Registrants’ Statements of Operations and
Comprehensive Income. Expense for finance leases is primarily recorded to Operating and maintenance on the Utility Registrants’ Statements of Operations
and Comprehensive Income.

Income from operating leases, including subleases, is recognized on a straight-line basis over the term of the lease, unless another systematic and rational
basis is more representative of the pattern in which income is earned over the term of the lease. Variable lease payments are recognized in the period in
which the related obligation is performed and consist primarily of payments received from sales of electricity under contracted generation and are based on
the  electricity  produced  by  those  generating  assets.  Operating  lease  income  and  variable  lease  payments  are  recorded  to  Operating  revenues  on  the
Registrants’ Statements of Operations and Comprehensive Income.

The Registrants’ operating and finance leases consist primarily of contracted generation, real estate including office buildings, and vehicles and equipment.
The Registrants generally account for contracted generation in which the generating asset is not renewable as a lease if the customer has dispatch rights
and  obtains  substantially  all  of  the  economic  benefits.  For  new  agreements  entered  after  January  1,  2019,  the  Registrants  generally  do  not  account  for
contracted generation in which the generating asset is renewable as a lease if the customer does not design the generating asset. The Registrants account
for land right arrangements that provide for exclusive use as leases while shared use land arrangements are generally not leases. The Registrants do not
account for secondary use pole attachments as leases.

See Note 11 — Leases for additional information.

Note 1 — Significant Accounting Policies

Income Taxes (All Registrants)

Deferred Federal and state income taxes are recorded on significant temporary differences between the book and tax basis of assets and liabilities and for
tax benefits carried forward. Investment tax credits have been deferred in the Registrants’ Consolidated Balance Sheets and are recognized in book income
over the life of the related property. The Registrants account for uncertain income tax positions using a benefit recognition model with a two-step approach; a
more-likely-than-not recognition criterion; and a measurement approach that measures the position as the largest amount of tax benefit that is greater than
50%  likely  of  being  realized  upon  ultimate  settlement.  If  it  is  not  more-likely-than-not  that  the  benefit  of  the  tax  position  will  be  sustained  on  its  technical
merits, no benefit is recorded. Uncertain tax positions that relate only to timing of when an item is included on a tax return are considered to have met the
recognition threshold. The Registrants recognize accrued interest related to unrecognized tax benefits in Interest expense, net or Other, net (interest income)
and recognize penalties related to unrecognized tax benefits in Other, net in their Consolidated Statements of Operations and Comprehensive Income.

Cash and Cash Equivalents (All Registrants)

The Registrants consider investments purchased with an original maturity of three months or less to be cash equivalents.

Restricted Cash and Cash Equivalents (All Registrants)

Restricted  cash  and  cash  equivalents  represent  funds  that  are  restricted  to  satisfy  designated  current  liabilities.  As  of  December  31,  2020  and  2019,  the
Registrants' restricted cash and cash equivalents primarily represented the following items:

Registrant
Exelon
Generation

ComEd
PECO
BGE

PHI
Pepco
DPL
ACE

Description
Payment of medical, dental, vision, and long-term disability benefits, in addition to the items listed for Generation and the Utility Registrants.
Project-specific nonrecourse financing structures for debt service and financing of operations of the underlying entities.
Collateral held from suppliers associated with energy and REC procurement contracts, any over-recovered RPS costs and alternative compliance
payments received from RES pursuant to FEJA, and costs for the remediation of an MGP site.
Proceeds from the sales of assets that were subject to PECO’s mortgage indenture.
Proceeds from the loan program for the completion of certain energy efficiency measures and collateral held from energy suppliers.
Payment of merger commitments, collateral held from its energy suppliers associated with procurement contracts, and repayment of Transition
Bonds.
Payment of merger commitments and collateral held from energy suppliers.
Collateral held from energy suppliers.
Repayment of Transition Bonds and collateral held from energy suppliers.

Restricted cash and cash equivalents not available to satisfy current liabilities are classified as noncurrent assets. As of December 31, 2020 and 2019, the
Registrants'  noncurrent  restricted  cash  and  cash  equivalents  primarily  represented  ComEd’s  over-recovered  RPS  costs  and  alternative  compliance
payments received from RES pursuant to FEJA and costs for the remediation of an MGP site, and ACE’s repayment of Transition Bonds.

See Note 24 — Supplemental Financial Information for additional information.

Allowance for Credit Losses on Accounts Receivables (All Registrants)

The  allowance  for  credit  losses  reflects  the  Registrants’  best  estimates  of  losses  on  the  customers'  accounts  receivable  balances  based  on  historical
experience, current information, and reasonable and supportable forecasts.

The  allowance  for  credit  losses  for  Generation’s  retail  customers  is  based  on  accounts  receivable  aging  historical  experience  coupled  with  specific
identification  through  a  credit  monitoring  process,  which  considers  current  conditions  and  forward-looking  information  such  as  industry  trends,
macroeconomic factors, changes in the regulatory environment, external credit ratings, publicly available news, payment status, payment history, and the

228

Note 1 — Significant Accounting Policies

exercise of collateral calls. The allowance for credit losses for Generation wholesale customers is developed using a credit monitoring process, similar to that
used  for  retail  customers.  When  a  wholesale  customer’s  risk  characteristics  are  no  longer  aligned  with  the  pooled  population,  Generation  uses  specific
identification to develop an allowance for credit losses. Adjustments to the allowance for credit losses are recorded in Operating and maintenance expense
on Generation’s Consolidated Statements of Operations and Comprehensive Income.

The allowance for credit losses for the Utility Registrants’ customers is developed by applying loss rates for each Utility Registrant, based on historical loss
experience,  current  conditions,  and  forward-looking  risk  factors,  to  the  outstanding  receivable  balance  by  customer  risk  segment.  Utility  Registrants'
customer accounts are written off consistent with approved regulatory requirements. Adjustments to the allowance for credit losses are primarily recorded to
Operating and maintenance expense on the Utility Registrants' Consolidated Statements of Operations and Comprehensive Income or Regulatory assets
and liabilities on the Utility Registrants' Consolidated Balance Sheets. See Note 3 - Regulatory Matters for additional information regarding the regulatory
recovery of credit losses on customer accounts receivable.

The Registrants have certain non-customer receivables in Other deferred debits and other assets which primarily are with governmental agencies and other
high-quality counterparties with no history of default.  As such, the allowance for credit losses related to these receivables is not material.  The Registrants
monitor these balances and will record an allowance if there are indicators of a decline in credit quality.

Variable Interest Entities (Exelon, Generation, PHI, and ACE)

Exelon accounts for its investments in and arrangements with VIEs based on the following specific requirements:

•

•

•

requires an entity to qualitatively assess whether it should consolidate a VIE based on whether the entity has a controlling financial interest,

requires an ongoing reconsideration of this assessment instead of only upon certain triggering events, and

requires the entity that consolidates a VIE (the primary beneficiary) to disclose (1) the assets of the consolidated VIE, if they can be used to only
settle specific obligations of the consolidated VIE, and (2) the liabilities of a consolidated VIE for which creditors do not have recourse to the general
credit of the primary beneficiary.

See Note 23 — Variable Interest Entities for additional information.

Inventories (All Registrants)

Inventory is recorded at the lower of weighted average cost or net realizable value. Provisions are recorded for excess and obsolete inventory. Fossil fuel,
materials and supplies, and emissions allowances are generally included in inventory when purchased. Fossil fuel and emissions allowances are expensed
to purchased power and fuel expense when used or sold. Materials and supplies generally includes transmission, distribution, and generating plant materials
and are expensed to operating and maintenance or capitalized to property, plant, and equipment, as appropriate, when installed or used.

Debt and Equity Security Investments (Exelon and Generation)

Debt Security Investments. Debt securities are reported at fair value and classified as available-for-sale securities. Unrealized gains and losses, net of tax,
are reported in OCI.

Equity  Security  Investments  without  Readily  Determinable  Fair  Values.  Exelon  has  certain  equity  securities  without  readily  determinable  fair
values.  Exelon  has  elected  to  use  the  practicability  exception  to  measure  these  investments,  defined  as  cost  adjusted  for  changes  from  observable
transactions for identical or similar investments of the same issuer, less impairment. Changes in measurement are reported in earnings.

Equity Security Investments with Readily Determinable Fair Values. Exelon has certain equity securities with readily determinable fair values. For equity
securities held in NDT funds, realized and unrealized gains and losses, net of tax, on Generation’s NDT funds associated with the Regulatory Agreement
Units are included in regulatory liabilities at Exelon, ComEd, and PECO, in Noncurrent payables to affiliates at Generation and in

229

Table of Contents

(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

Noncurrent receivables from affiliates at ComEd and PECO. Realized and unrealized gains and losses, net of tax, on Generation’s NDT funds associated
with the Non-Regulatory Agreement Units are included in earnings at Exelon and Generation. Exelon's and Generation's NDT funds are classified as current
or  noncurrent  assets,  depending  on  the  timing  of  the  decommissioning  activities  and  income  taxes  on  trust  earnings.  For  all  other  equity  securities  with
readily  determinable  fair  values,  realized  and  unrealized  gains  and  losses  are  included  in  earnings  at  Exelon  and  Generation.  See  Note  3  —  Regulatory
Matters  for  additional  information  regarding  ComEd’s  and  PECO’s  regulatory  assets  and  liabilities  and  Note  18  —  Fair  Value  of  Financial  Assets  and
Liabilities and Note 10 — Asset Retirement Obligations for additional information.

Property, Plant, and Equipment (All Registrants)

Property, plant, and equipment is recorded at original cost. Original cost includes construction-related direct labor and material costs. The Utility Registrants
also include indirect construction costs including labor and related costs of departments associated with supporting construction activities. When appropriate,
original cost also includes capitalized interest for Generation, Exelon Corporate, and PHI and AFUDC for regulated property at the Utility Registrants. The
cost  of  repairs  and  maintenance,  including  planned  major  maintenance  activities  and  minor  replacements  of  property,  is  charged  to  Operating  and
maintenance expense as incurred.

Third parties reimburse the Utility Registrants for all or a portion of expenditures for certain capital projects. Such contributions in aid of construction costs
(CIAC)  are  recorded  as  a  reduction  to  Property,  plant,  and  equipment,  net.  DOE  SGIG  and  other  funds  reimbursed  to  the  Utility  Registrants  have  been
accounted for as CIAC.

For  Generation,  upon  retirement,  the  cost  of  property  is  generally  charged  to  accumulated  depreciation  in  accordance  with  the  composite  and  group
methods of depreciation. Upon replacement of an asset, the costs to remove the asset, net of salvage, are capitalized to gross plant when incurred as part of
the cost of the newly-installed asset and recorded to depreciation expense over the life of the new asset. Removal costs, net of salvage, incurred for property
that will not be replaced is charged to Operating and maintenance expense as incurred.

For the Utility Registrants, upon retirement, the cost of property, net of salvage, is charged to accumulated depreciation consistent with the composite and
group methods of depreciation. Depreciation expense at ComEd, BGE, Pepco, DPL, and ACE includes the estimated cost of dismantling and removing plant
from service upon retirement. Actual incurred removal costs are applied against a related regulatory liability or recorded to a regulatory asset if in excess of
previously collected removal costs. PECO’s removal costs are capitalized to accumulated depreciation when incurred and recorded to depreciation expense
over the life of the new asset constructed consistent with PECO’s regulatory recovery method.

Capitalized Software. Certain costs, such as design, coding, and testing incurred during the application development stage of software projects that are
internally developed or purchased for operational use are capitalized within Property, plant, and equipment. Similar costs incurred for cloud-based solutions
treated as service arrangements are capitalized within Other Current Assets and Deferred Debits and Other Assets. Such capitalized amounts are amortized
ratably over the expected lives of the projects when they become operational, generally not to exceed five years. Certain other capitalized software costs are
being amortized over longer lives based on the expected life or pursuant to prescribed regulatory requirements.

Capitalized Interest and AFUDC. During construction, Exelon and Generation capitalize the costs of debt funds used to finance non-regulated construction
projects. Capitalization of debt funds is recorded as a charge to construction work in progress and as a non-cash credit to interest expense.

AFUDC  is  the  cost,  during  the  period  of  construction,  of  debt  and  equity  funds  used  to  finance  construction  projects  for  regulated  operations.  AFUDC  is
recorded  to  construction  work  in  progress  and  as  a  non-cash  credit  to  an  allowance  that  is  included  in  interest  expense  for  debt-related  funds  and  other
income and deductions for equity-related funds. The rates used for capitalizing AFUDC are computed under a method prescribed by regulatory authorities.

See  Note  8  —  Property,  Plant,  and  Equipment,  Note  9  —  Jointly  Owned  Electric  Utility  Plant  and  Note  24  —  Supplemental  Financial  Information  for
additional information regarding property, plant and equipment.

(Dollars in millions, except per share data unless otherwise noted)

Note 1 — Significant Accounting Policies

Nuclear Fuel (Exelon and Generation)

The cost of nuclear fuel is capitalized within Property, plant, and equipment and charged to fuel expense using the unit-of-production method. Any potential
future SNF disposal fees will be expensed through fuel expense. Additionally, certain on-site SNF storage costs are being reimbursed by the DOE since a
DOE (or government-owned) long-term storage facility has not been completed. See Note 19 — Commitments and Contingencies for additional information
regarding the cost of SNF storage and disposal.

Nuclear Outage Costs (Exelon and Generation)

Costs associated with nuclear outages, including planned major maintenance activities, are expensed to Operating and maintenance expense or capitalized
to Property, plant, and equipment (based on the nature of the activities) in the period incurred.

Depreciation and Amortization (All Registrants)

Except for the amortization of nuclear fuel, depreciation is generally recorded over the estimated service lives of property, plant, and equipment on a straight-
line  basis  using  the  group,  composite  or  unitary  methods  of  depreciation.  The  group  approach  is  typically  for  groups  of  similar  assets  that  have
approximately  the  same  useful  lives  and  the  composite  approach  is  used  for  dissimilar  assets  that  have  different  lives.  Under  both  methods,  a  reporting
entity  depreciates  the  assets  over  the  average  life  of  the  assets  in  the  group.  ComEd,  BGE,  Pepco,  DPL,  and  ACE's  depreciation  expense  includes  the
estimated cost of dismantling and removing plant from service upon retirement, which is consistent with each utility's regulatory recovery method. PECO's
removal costs are capitalized to accumulated depreciation when incurred, and recorded to depreciation expense over the life of the new asset constructed
consistent  with  PECO's  regulatory  recovery  method.  The  estimated  service  lives  for  the  Registrants  are  based  on  a  combination  of  depreciation  studies,
historical retirements, site licenses, and management estimates of operating costs and expected future energy market conditions. See Note 7 — Early Plant
Retirements for additional information on the impacts of early plant retirements.

See Note 8 — Property, Plant, and Equipment for additional information regarding depreciation.

Amortization  of  regulatory  assets  and  liabilities  are  recorded  over  the  recovery  or  refund  period  specified  in  the  related  legislation  or  regulatory  order  or
agreement. When the recovery or refund period is less than one year, amortization is recorded to the line item in which the deferred cost or income would
have  originally  been  recorded  in  the  Utility  Registrants’  Consolidated  Statements  of  Operations  and  Comprehensive  Income.  Amortization  of  ComEd’s
electric distribution and energy efficiency formula rate regulatory assets and the Utility Registrants' transmission formula rate regulatory assets is recorded to
Operating revenues.

Amortization of income tax related regulatory assets and liabilities is generally recorded to Income tax expense. With the exception of the regulatory assets
and liabilities discussed above, when the recovery period is more than one year, the amortization is generally recorded to Depreciation and amortization in
the Registrants’ Consolidated Statements of Operations and Comprehensive Income.

See  Note  3  —  Regulatory  Matters  and  Note  24  —  Supplemental  Financial  Information  for  additional  information  regarding  Generation’s  nuclear  fuel  and
ARC, and the amortization of the Utility Registrants' regulatory assets.

Asset Retirement Obligations (All Registrants)

Generation  estimates  and  recognizes  a  liability  for  its  legal  obligation  to  perform  asset  retirement  activities  even  though  the  timing  and/or  methods  of
settlement  may  be  conditional  on  future  events.  Generation  generally  updates  its  nuclear  decommissioning  ARO  annually,  unless  circumstances  warrant
more  frequent  updates,  based  on  its  annual  evaluation  of  cost  escalation  factors  and  probabilities  assigned  to  the  multiple  outcome  scenarios  within  its
probability-weighted discounted cash flow models. Generation’s multiple outcome scenarios are generally based on decommissioning cost studies which are
updated, on a rotational basis, for each of Generation’s nuclear units at least every five years, unless circumstances warrant more frequent updates. AROs
are accreted throughout each year to reflect the time value of money for these present value obligations through a charge to Operating and maintenance
expense  in  the  Consolidated  Statements  of  Operations  and  Comprehensive  Income  for  Non-Regulatory  Agreement  Units  and  through  a  decrease  to
regulatory liabilities for Regulatory Agreement Units or, in the case of the Utility Registrants' accretion, through an increase to regulatory assets. See Note 10
— Asset Retirement Obligations for additional information.

Note 1 — Significant Accounting Policies

Guarantees (All Registrants)

If necessary, the Registrants recognize a liability at the time of issuance of a guarantee for the fair market value of the obligations they have undertaken by
issuing the guarantee. The liability is reduced or eliminated as the Registrants are released from risk under the guarantee. Depending on the nature of the
guarantee, the release from risk of the Registrant may be recognized only upon the expiration or settlement of the guarantee or by a systematic and rational
amortization method over the term of the guarantee. See Note 19 — Commitments and Contingencies for additional information.

Asset Impairments

Long-Lived  Assets  (All  Registrants).  The  Registrants  regularly  monitor  and  evaluate  the  carrying  value  of  long-lived  assets  and  asset  groups  for
recoverability  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  value  of  those  assets  may  not  be  recoverable.  Indicators  of
impairment may include a deteriorating business climate, including, but not limited to, declines in energy prices, condition of the asset, specific regulatory
disallowance, or plans to dispose of a long-lived asset significantly before the end of its useful life. The Registrants determine if long-lived assets and asset
groups are impaired by comparing the undiscounted expected future cash flows to the carrying value. When the undiscounted cash flow analysis indicates a
long-lived asset or asset group is not recoverable, the amount of the impairment loss is determined by measuring the excess of the carrying amount of the
long-lived asset or asset group over its fair value. See Note 12 — Asset Impairments for additional information.

Goodwill (Exelon, ComEd, and PHI). Goodwill represents the excess of the purchase price paid over the estimated fair value of the net assets acquired
and liabilities assumed in the acquisition of a business. Goodwill is not amortized, but is assessed for impairment at least annually or on an interim basis if an
event  occurs  or  circumstances  change  that  would  more  likely  than  not  reduce  the  fair  value  of  a  reporting  unit  below  its  carrying  value.  See  Note  13  —
Intangible Assets for additional information.

Equity  Method  Investments  (Exelon  and  Generation).  Exelon  and  Generation  regularly  monitor  and  evaluate  equity  method  investments  to  determine
whether  they  are  impaired.  An  impairment  is  recorded  when  the  investment  has  experienced  a  decline  in  value  that  is  other-than-temporary  in  nature.
Additionally, if the entity in which Generation holds an investment recognizes an impairment loss, Exelon and Generation would record their proportionate
share of that impairment loss and evaluate the investment for an other-than-temporary decline in value.

Debt  Security  Investments  (Exelon  and  Generation).  Declines  in  the  fair  value  of  debt  security  investments  below  the  cost  basis  are  reviewed
to determine if such declines are other-than-temporary. If the decline is determined to be other-than-temporary, the amount of the impairment loss is included
in earnings.

Equity Security Investments (Exelon and Generation). Equity investments with readily determinable fair values are measured and recorded at fair value
with any changes in fair value recorded through earnings. Investments in equity securities without readily determinable fair values are qualitatively assessed
for impairment each reporting period. If it is determined that the equity security is impaired on the basis of the qualitative assessment, an impairment loss will
be recognized in earnings to the amount by which the security’s carrying amount exceeds its fair value.

Derivative Financial Instruments (All Registrants)

All derivatives are recognized on the balance sheet at their fair value unless they qualify for certain exceptions, including the NPNS. For derivatives intended
to  serve  as  economic  hedges,  changes  in  fair  value  are  recognized  in  earnings  each  period.  Amounts  classified  in  earnings  are  included  in  Operating
revenue, Purchased power and fuel, Interest expense, or Other, net in the Consolidated Statements of Operations and Comprehensive Income based on the
activity the transaction is economically hedging. While the majority of the derivatives serve as economic hedges, there are also derivatives entered into for
proprietary trading purposes, subject to Exelon’s Risk Management Policy, and changes in the fair value of those derivatives are recorded in revenue in the
Consolidated Statements of Operations and Comprehensive Income. At the Utility Registrants, changes in fair value may be recorded as a regulatory asset
or  liability  if  there  is  an  ability  to  recover  or  return  the  associated  costs.  Cash  inflows  and  outflows  related  to  derivative  instruments  are  included  as  a
component of operating, investing, or financing cash flows in the Consolidated Statements of Cash Flows, depending on the nature of each transaction. On
July 1, 2018, Exelon and Generation de-designated its fair value and cash flow

hedges. See Note 3 — Regulatory Matters and Note 16 — Derivative Financial Instruments for additional information.

As part of Generation’s energy marketing business, Generation enters into contracts to buy and sell energy to meet the requirements of its customers. These
contracts include short-term and long-term commitments to purchase and sell energy and energy-related products in the energy markets with the intent and
ability to deliver or take delivery of the underlying physical commodity. NPNS are contracts where physical delivery is probable, quantities are expected to be
used  or  sold in the normal course of business over  a  reasonable  period  of  time  and  will  not  be  financially  settled.  Revenues  and  expenses  on  derivative
contracts  that  qualify,  and  are  designated,  as  NPNS  are  recognized  when  the  underlying  physical  transaction  is  completed.  While  these  contracts  are
considered derivative financial instruments, they are not required to be recorded at fair value, but rather are recorded on an accrual basis of accounting. See
Note 16 — Derivative Financial Instruments for additional information.

Retirement Benefits (All Registrants)

Exelon sponsors defined benefit pension plans and OPEB plans for essentially all current employees.

The  plan  obligations  and  costs  of  providing  benefits  under  these  plans  are  measured  as  of  December  31.  The  measurement  involves  various  factors,
assumptions, and accounting elections. The impact of assumption changes or experience different from that assumed on pension and OPEB obligations is
recognized  over  time  rather  than  immediately  recognized  in  the  Consolidated  Statements  of  Operations  and  Comprehensive  Income.  Gains  or  losses  in
excess of the greater of ten percent of the projected benefit obligation or the MRV of plan assets are amortized over the expected average remaining service
period of plan participants. See Note 15 — Retirement Benefits for additional information.

New Accounting Standards (All Registrants)

New Accounting Standards Adopted in 2020: In 2020, the Registrants adopted the following new authoritative accounting guidance issued by the FASB.

Impairment of Financial Instruments (Issued June 2016). Provides for a new Current Expected Credit Loss (CECL) impairment model for specified financial
instruments  including  loans,  trade  receivables,  debt  securities  classified  as  held-to-maturity  investments,  and  net  investments  in  leases  recognized  by  a
lessor. Under the new guidance, on initial recognition and at each reporting period, an entity is required to recognize an allowance that reflects its current
estimate of credit losses expected to be incurred over the life of the financial instrument based on historical experience, current conditions, and reasonable
and supportable forecasts. The standard was effective January 1, 2020 and requires a modified retrospective transition approach through a cumulative-effect
adjustment to retained earnings as of the beginning of the period of adoption. This standard is primarily applicable to Generation's and the Utility Registrants'
trade accounts receivables balances. The guidance did not have a significant impact on the Registrants' consolidated financial statements.

Goodwill Impairment (Issued January 2017). Simplifies  the  accounting  for  goodwill  impairment  by  removing  Step  2  of  the  current  impairment  assessment
model,  which  requires  calculation  of  a  hypothetical  purchase  price  allocation.  Under  the  revised  guidance,  goodwill  impairment  will  be  measured  as  the
amount  by  which  a  reporting  unit’s  carrying  value  exceeds  its  fair  value,  not  to  exceed  the  carrying  amount  of  goodwill  (currently  Step  1  of  the  two-step
impairment assessment). Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment assessment
is necessary. The standard was effective January 1, 2020 and must be applied on a prospective basis. Exelon, ComEd, and PHI adopted the new guidance
in  2020.  The  new  guidance  did  not  impact  Exelon's,  ComEd's,  and  PHI's  2020  annual  goodwill  impairment  assessments  as  they  performed  a  qualitative
assessment.

2. Mergers, Acquisitions, and Dispositions (Exelon and Generation)

CENG Put Option (Exelon and Generation)

Generation owns a 50.01% membership interest in CENG, a joint venture with EDF, which wholly owns the Calvert Cliffs and Ginna nuclear stations and
Nine Mile Point Unit 1, in addition to an 82% undivided ownership

Note 2 — Mergers, Acquisitions, and Dispositions

interest in Nine Mile Point Unit 2. CENG is 100% consolidated in Exelon's and Generation's financial statements. See Note 23 — Variable Interest Entities
for additional information.

On April 1, 2014, Generation and EDF entered into various agreements including a NOSA, an amended LLC Operating Agreement, an Employee Matters
Agreement, and a Put Option Agreement, among others. Under the amended LLC Operating Agreement, CENG made a $400 million special distribution to
EDF  and  committed  to  make  preferred  distributions  to  Generation  until  Generation  has  received  aggregate  distributions  of  $400  million  plus  a  return  of
8.50% per annum. Under the Put Option Agreement, EDF has the option to sell its 49.99% equity interest in CENG to Generation exercisable beginning on
January 1, 2016 and thereafter until June 30, 2022. On November 20, 2019, Generation received notice of EDF’s intention to exercise the put option to sell
its interest in CENG to Generation, and the put automatically exercised on January 19, 2020 at the end of the sixty-day advance notice period.

Under the terms of the Put Option Agreement, the purchase price is to be determined by agreement of the parties, or absent such agreement, by a third-
party arbitration process. The third parties determining fair market value of EDF’s 49.99% interest are to take into consideration all rights and obligations
under the LLC Operating Agreement and Employee Matters Agreement including but not limited to Generation’s rights with respect to any unpaid aggregate
preferred  distributions  and  the  related  return.  As  of  December  31,  2020,  the  total  unpaid  aggregate  preferred  distributions  and  related  return  owed  to
Generation is $619 million. At this time, Generation cannot reasonably predict the ultimate purchase price that will be paid to EDF for its interest in CENG.
The  transaction  will  require  approval  by  the  NYPSC  and  the  FERC.  The  FERC  approval  was  obtained  on  July  30,  2020.  The  process  and  regulatory
approvals are expected to close in the second half of 2021.

Agreement for Sale of Generation’s Solar Business (Exelon and Generation)

On December 8, 2020, Generation entered into an agreement with an affiliate of Brookfield Renewable, for the sale of a significant portion of Generation’s
solar business, including 360 megawatts of generation in operation or under construction across more than 600 sites across the United States. Under the
terms  of  the  transaction,  the  purchase  price  is  $810  million,  subject  to  certain  working  capital  and  other  post-closing  adjustments.  Generation  will  retain
certain solar assets not included in this agreement, primarily Antelope Valley.

As a result of the transaction, in the fourth quarter of 2020, Exelon and Generation reclassified the solar assets and liabilities on Exelon’s and Generation’s
Consolidated Balance Sheets as held for sale. The transaction is expected to result in an estimated pre-tax gain ranging from $75 million to $125 million.
The  gain  will  be  recorded  in  Gain  on  sales  of  assets  and  businesses  in  Exelon’s  and  Generation’s  Consolidated  Statements  of  Operations  and
Comprehensive Income upon completion of the transaction. Completion of the transaction contemplated by the sale agreement is subject to the satisfaction
of several closing conditions and is expected to occur in the first half of 2021. See Note 17 — Debt and Credit Agreements for additional information on the
SolGen nonrecourse debt included as part of the transaction.

Disposition of Oyster Creek (Exelon and Generation)

On July 31, 2018, Generation entered into an agreement with Holtec and its indirect wholly owned subsidiary, OCEP, for the sale and decommissioning of
Oyster Creek located in Forked River, New Jersey, which permanently ceased generation operations on September 17, 2018. Completion of the transaction
contemplated by the sale agreement was subject to the satisfaction of several closing conditions, including approval of the license transfer from the NRC and
other  regulatory  approvals,  and  a  private  letter  ruling  from  the  IRS,  which  were  satisfied  in  the  second  quarter  2019.  The  sale  was  completed  on  July  1,
2019. Exelon and Generation recognized a loss on the sale in the third quarter of 2019, which was immaterial.

Under the terms of the transaction, Generation transferred to OCEP substantially all the assets associated with Oyster Creek, including assets held in NDT
funds, along with the assumption of liability for all responsibility for the site, including full decommissioning and ongoing management of spent fuel until the
spent fuel is moved offsite. The terms of the transaction also include various forms of performance assurance for the obligations of OCEP to timely complete
the required decommissioning, including a parental guaranty from Holtec for all performance and payment obligations of OCEP, and a requirement for Holtec
to deliver a letter of credit to Generation upon the occurrence of specified events.

Note 2 — Mergers, Acquisitions, and Dispositions

Upon  remeasurement  of  the  Oyster  Creek  ARO,  Exelon  and  Generation  recognized  an  $84  million  and  a  $9  million  pre-tax  charge  to  Operating  and
maintenance expense in 2018 and in 2019, respectively. See Note 10 — Asset Retirement Obligations for additional information.

Disposition of Electrical Contracting Business (Exelon and Generation)

On  February  28,  2018,  Generation  completed  the  sale  of  its  interest  in  an  electrical  contracting  business  that  primarily  installs,  maintains,  and  repairs
underground and high-voltage cable transmission and distribution systems for $87 million, resulting in a pre-tax gain which is included within Gain on sales
of assets and businesses in Exelon's and Generation's Consolidated Statements of Operations and Comprehensive Income for the year ended December
31, 2018.

(a) Pursuant  to  EIMA  and  FEJA,  ComEd’s  electric  distribution  rates  are  established  through  a  performance-based  formula,  which  sunsets  at  the  end  of  2022.  The  electric
distribution formula rate includes decoupling provisions and, as a result, ComEd's electric distribution formula rate revenues are not impacted by abnormal weather, usage
per customer, or number of customers. ComEd is required to file an annual update to its electric distribution formula rate on or before May 1 , with resulting rates effective
in January of the following year. ComEd’s annual electric distribution formula rate update is based on prior year actual costs and current year projected capital additions
(initial year revenue requirement). The update also reconciles any differences between the revenue requirement in effect for the prior year and actual costs incurred from
the year (annual reconciliation).

st

ComEd’s 2020 approved revenue requirement above reflects an increase of $51 million for the initial year revenue requirement for 2020 and a decrease of $68 million
related to the annual reconciliation for 2018. The revenue requirement for 2020 and the revenue requirement for 2018 provides for a weighted average debt and equity
return on distribution rate

base of 6.51% inclusive of an allowed ROE of 8.91%, reflecting the monthly average yields for 30-year treasury bonds plus 580 basis points.

ComEd’s 2021 approved revenue requirement above reflects an increase of $50 million for the initial year revenue requirement for 2021 and a decrease of $64 million
related  to  the  annual  reconciliation  for  2019.  The  revenue  requirement  for  2021  and  the  revenue  requirement  for  2019  provide  for  a  weighted  average  debt  and  equity
return on distribution rate base of 6.28% inclusive of an allowed ROE of 8.38%, reflecting the monthly average yields for 30-year treasury bonds plus 580 basis points. See
table below for ComEd's regulatory assets associated with its electric distribution formula rate.

(b) Reflects a three-year cumulative multi-year plan for 2021 through 2023. The MDPSC awarded BGE electric revenue requirement increases of $59 million, $39 million, and
$42  million  in  2021,  2022,  and  2023,  respectively,  and  natural  gas  revenue  requirement  increases  of  $53  million,  $11  million,  and  $10  million  in  2021,  2022,  and  2023,
respectively. However, the MDPSC utilized certain tax benefits to fully offset the increases in 2021 so that customer rates will remain unchanged from 2020 to 2021. The
MDPSC has deferred a decision on whether to use certain tax benefits to offset the revenue requirement increases in 2022 and 2023 and BGE cannot predict the outcome.

(d) Requested increases are before New Jersey sales and use tax. ACE intends to put rates into effect on September 8, 2021, subject to refund.

Transmission Formula Rates (Exelon, PHI, and the Utility Registrants)

The Utility Registrants' transmission rates are each established based on a FERC-approved formula. ComEd, BGE, Pepco, DPL, and ACE are required to
file an annual update to the FERC-approved formula on or before May 15, and PECO is required to file on or before May 31, with the resulting rates effective
on  June  1  of  the  same  year.  The  annual  update  for  ComEd,  BGE,  DPL,  and  ACE  is  based  on  prior  year  actual  costs  and  current  year  projected  capital
additions (initial year revenue requirement). The annual update for PECO is based on prior year actual costs and current year projected capital additions,
accumulated  depreciation,  and  accumulated  deferred  income  taxes.  The  annual  update  for  Pepco  is  based  on  prior  year  actual  costs  and  current  year
projected  capital  additions,  accumulated  depreciation,  depreciation  and  amortization  expense,  and  accumulated  deferred  income  taxes.  The  update  for
ComEd, BGE, DPL, and ACE also reconciles any differences between the revenue requirement in effect beginning June 1 of the prior year and actual costs
incurred for that year (annual reconciliation). The update for PECO and Pepco also reconciles any differences between the actual costs and actual revenues
for the calendar year (annual reconciliation).

Energy Efficiency Formula Rate (Exelon and ComEd). FEJA allows ComEd to defer energy efficiency costs (except for any voltage optimization costs
which are recovered through the electric distribution formula rate) as a separate regulatory asset that is recovered through the energy efficiency formula rate
over the weighted average useful life, as approved by the ICC, of the related energy efficiency measures. ComEd earns a return on the energy efficiency
regulatory  asset  at  a  rate  equal  to  its  weighted  average  cost  of  capital,  which  is  based  on  a  year-end  capital  structure  and  calculated  using  the  same
methodology applicable to ComEd’s electric distribution formula rate. Beginning January 1, 2018 through December 31, 2030, the ROE that ComEd earns
on  its  energy  efficiency  regulatory  asset  is  subject  to  a  maximum  downward  or  upward  adjustment  of  200  basis  points  if  ComEd’s  cumulative  persisting
annual MWh savings falls short of or exceeds specified percentage benchmarks of its annual incremental savings goal. ComEd is required to file an update
to  its  energy  efficiency  formula  rate  on  or  before  June  1   each  year,  with  resulting  rates  effective  in  January  of  the  following  year.  The  annual  update  is
based  on  projected  current  year  energy  efficiency  costs,  PJM  capacity  revenues,  and  the  projected  year-end  regulatory  asset  balance  less  any  related
deferred income taxes (initial year revenue requirement). The update also reconciles any differences between the revenue requirement in effect for the prior
year  and  actual  costs  incurred  from  the  year  (annual  reconciliation).  The  approved  energy  efficiency  formula  rate  also  provides  for  revenue  decoupling
provisions similar to those in ComEd’s electric distribution formula rate.

asset and rate base of 6.28% inclusive of an allowed ROE of 8.38%, reflecting the monthly average yields for 30-year treasury bonds plus 580 basis points. The revenue
requirement for 2019 provides for a weighted average debt and equity return on the energy efficiency regulatory asset and rate base of 6.56% inclusive of an allowed ROE
of 8.96%, which includes an upward performance adjustment that can either increase or decrease the ROE. See table below for ComEd's regulatory assets associated with
its energy efficiency formula rate.

Maryland Regulatory Matters

The Maryland Strategic Infrastructure Development and Enhancement Program (Exelon and BGE). On December 1, 2017 (as amended on January
22, 2018), BGE filed an application with the MDPSC seeking approval for a new gas infrastructure replacement plan and associated surcharge, effective for
the  five-year  period  from  2019  through  2023.  On  May  30,  2018,  the  MDPSC  approved  with  modifications  a  new  infrastructure  plan  and  associated
surcharge, subject to BGE's acceptance of the Order. On June 1, 2018, BGE accepted the MDPSC Order and the associated surcharge became effective
January  2019.  The  five-year  plan  calls  for  capital  expenditures  over  the  2019-2023  timeframe  of  $732  million  with  an  associated  revenue  requirement  of
$200 million.

Cash Working Capital Order (Exelon and BGE). On November 17, 2016, the MDPSC rendered a decision in the proceeding to review BGE’s request to
recover its cash working capital (CWC) requirement for its POLR service, also known as SOS, as well as other components that make up the Administrative
Charge,  the  mechanism  that  enables  BGE  to  recover  its  SOS-related  costs.  The  Administrative  Charge  is  comprised  of  five  components:  CWC,
uncollectibles, incremental costs, return, and an administrative adjustment, which acts as a proxy for retail suppliers’ costs. The MDPSC accepted BGE's
positions on recovery of CWC and pass-through recovery of BGE’s actual uncollectibles and incremental costs. The order also grants BGE a return on the
SOS. Subsequently, the MDPSC Staff and residential consumer advocate sought clarification and appealed the amount of return awarded to BGE on the
SOS. On July 27, 2020, the Maryland Court of Special Appeals affirmed the circuit court’s judgment affirming the MDPSC’s decision. No party appealed the
decision to the Maryland Court of Appeals. Also, in BGE’s 2019 electric and gas distribution base rate proceeding, the MDPSC established a normalized
administrative adjustment. However, a group of electric suppliers appealed the MDPSC’s decision to the Circuit Court for Baltimore City. BGE cannot predict
the outcome of this appeal.

New Jersey Regulatory Matters

ACE Infrastructure Investment Program Filing (Exelon, PHI, and ACE). On February 28, 2018, ACE filed with the NJBPU the company’s IIP proposing to
seek recovery of a series of investments through a new rider mechanism, totaling $338 million, between 2019-2022 to provide safe and reliable service for
its customers. The IIP will allow for more timely recovery of investments made to modernize and enhance ACE’s electric system. On April 15, 2019, ACE
entered into a settlement agreement with other parties, which allows for a recovery totaling $96 million of reliability related capital investments from July 1,
2019 through June 30, 2023. On April 18, 2019, the NJBPU approved the settlement agreement.

Advanced Metering Infrastructure Filing (Exelon, PHI, and ACE). On August 26, 2020, ACE filed an application with the NJBPU as was required seeking
approval to deploy a smart energy network in alignment with New Jersey’s Energy Master Plan and Clean Energy Act. The proposal consists of estimated
costs totaling $220 million, with deployment taking place over a 3-year implementation period from approximately 2021 to 2024 that involves the installation
of an integrated system of smart meters for all customers accompanied by the requisite communications facilities and data management systems. ACE is
seeking  authority  to  recover  these  estimated  investments  through  a  combination  of  the  ACE  IIP  rider  mechanism  and  future  distribution  base  rates.  ACE
currently expects a decision in this matter in the third quarter of 2021 but cannot predict if the NJBPU will approve the application as filed.

Note 3 — Regulatory Matters

New  Jersey  Clean  Energy  Legislation  (Exelon,  PHI,  and  ACE). On  May  23,  2018,  New  Jersey  enacted  legislation  that  established  and  modified  New
Jersey’s  clean  energy  and  energy  efficiency  programs  and  solar  and  RPS.  On  the  same  day,  New  Jersey  enacted  legislation  that  established  a  ZEC
program  that  provides  compensation  for  nuclear  plants  that  demonstrate  to  the  NJBPU  that  they  meet  certain  requirements,  including  that  they  make  a
significant  contribution  to  air  quality  in  the  state  and  that  their  revenues  are  insufficient  to  cover  their  costs  and  risks.  Electric  distribution  utilities  in  New
Jersey,  including  ACE,  began  collecting  from  retail  distribution  customers,  through  a  non-bypassable  charge,  all  costs  associated  with  the  utility’s
procurement of the ZECs effective April 18, 2019. See Generation Regulatory Matters below for additional information.

Other Federal Regulatory Matters

Transmission-Related Income Tax Regulatory Assets (Exelon, ComEd, BGE, PHI, Pepco, DPL, and ACE). On December 13, 2016 (and as amended
on  March  13,  2017),  BGE  filed  with  FERC  to  begin  recovering  certain  existing  and  future  transmission-related  income  tax  regulatory  assets  through  its
transmission formula rate. BGE’s existing regulatory assets included (1) amounts that, if BGE’s transmission formula rate provided for recovery, would have
been previously amortized and (2) amounts that would be amortized and recovered prospectively. On November 16, 2017, FERC issued an order rejecting
BGE’s proposed revisions to its transmission formula rate to recover these transmission-related income tax regulatory assets. In the fourth quarter of 2017,
ComEd,  BGE,  Pepco,  DPL,  and  ACE  fully  impaired  their  associated  transmission-related  income  tax  regulatory  assets  for  the  portion  of  the  income  tax
regulatory assets that would have been previously amortized.

On  February  23,  2018  (as  amended  on  July  9,  2018),  ComEd,  Pepco,  DPL,  and  ACE  each  filed  with  FERC  to  revise  their  transmission  formula  rate
mechanisms to permit recovery of transmission-related income tax regulatory assets, including those amounts that would have been previously amortized
and recovered through rates had the transmission formula rate provided for such recovery.

On September 7, 2018, FERC issued orders rejecting 1) BGE’s rehearing request of FERC's November 16, 2017 order and 2) the February 23, 2018 (as
amended on July 9, 2018) filing by ComEd, Pepco, DPL, and ACE for similar recovery.

On November 2, 2018, BGE filed an appeal of FERC's September 7, 2018 order to the U.S. Court of Appeals for the D.C. Circuit. On March 27, 2020, the
U.S. Court of Appeals for the D.C. Circuit Court denied BGE’s November 2, 2018 appeal.

On  October  1,  2018,  ComEd,  BGE,  Pepco,  DPL,  and  ACE  submitted  filings  to  recover  ongoing  non-TCJA  amortization  amounts  and  credit  TCJA
transmission-related income tax regulatory liabilities to customers for the prospective period starting on October 1, 2018. On April 26, 2019, FERC issued an
order accepting ComEd's, BGE's, Pepco's, DPL's, and ACE's October 1, 2018 filings, effective October 1, 2018, subject to refund and established hearing
and settlement judge procedures. On April 24, 2020, ComEd, BGE, Pepco, DPL, ACE, and other parties filed a settlement agreement with FERC, which
FERC approved on September 24, 2020. The settlement agreement provides for the recovery of ongoing transmission-related income tax regulatory assets
and  establishes  the  amount  and  amortization  period  for  excess  deferred  income  taxes  resulting  from  TCJA.  The  settlement  resulted  in  a  reduction  to
Operating revenues and an offsetting reduction to Income tax expense in the second quarter of 2020.

Regulatory Assets and Liabilities

Regulatory  assets  represent  incurred  costs  that  have  been  deferred  because  of  their  probable  future  recovery  from  customers  through  regulated  rates.
Regulatory liabilities represent the excess recovery of costs or accrued credits that have been deferred because it is probable such amounts will be returned
to customers through future regulated rates or represent billings in advance of expenditures for approved regulatory programs.

Recovery/Refund Period

Return

Pension and OPEB

Primarily reflects the Utility Registrants' portion of deferred
costs, including unamortized actuarial losses (gains) and prior
service costs (credits), associated with Exelon's pension and
OPEB plans, which are recovered through customer rates
once amortized through net periodic benefit cost. Also,
includes the Utility Registrants' non–service cost components
capitalized in Property, plant and equipment, net on their
Consolidated Balance Sheets.

Pension and OPEB - merger
related

The deferred costs are amortized over the plan participants'
average remaining service periods subject to applicable
pension and OPEB cost recognition policies. See Note 15 —
Retirement Benefits for additional information. The capitalized
non–service cost components are amortized over the lives of
the underlying assets.

Deferred income taxes

Deferred income taxes that are recoverable or refundable
through customer rates, primarily associated with accelerated
depreciation, the equity component of AFUDC, and the
effects of income tax rate changes, including those resulting
from the TCJA. These amounts include transmission-related
regulatory liabilities that require FERC approval separate from
the transmission formula rate. See Transmission-Related
Income Tax Regulatory Assets section above for additional
information.

The deferred costs are
amortized over the plan
participants' average
remaining service periods
subject to applicable pension
and OPEB cost recognition
policies. See Note 15 —
Retirement Benefits for
additional information. The
capitalized non–service cost
components are amortized
over the lives of the underlying
assets.

Legacy Constellation - 2038

Legacy PHI - 2032

Over the period in which the
related deferred income taxes
reverse, which is generally
based on the expected life of
the underlying assets. For
TCJA, generally refunded over
the remaining depreciable life
of the underlying assets,
except in certain jurisdictions
where the commissions have
approved a shorter refund
period for certain assets not
subject to IRS normalization
rules.

COVID-19 (Exelon and the Utility Registrants). Starting in March of 2020, the Utility Registrants temporarily suspended customer disconnections for non-
payment and temporarily ceased new late payment fees for all customers and restored service to customers upon request who were disconnected in the last
twelve months. The duration and extent of these measures varies by jurisdiction. While these measures are no longer in place for some jurisdictions as of
December 31, 2020, they are expected to continue through the first quarter of 2021 in other jurisdictions. Typically, the Utility Registrants recover credit loss
expense  through  regulatory  required  programs  or  distribution  base  rate  cases.  ComEd  and  ACE  have  existing  mechanisms  for  recovery  of  credit  loss
expense. For those jurisdictions without an existing regulatory required program to recover credit loss expense, the Utility Registrants are pursuing strategies
to recover incremental costs being incurred as a result of COVID-19:

•

•

In  the  period  of  April  to  July  of  2020,  the  MDPSC,  the  DCPSC,  the  DPSC,  and  the  NJBPU  issued  orders  authorizing  the  creation  of  regulatory
assets to track incremental COVID-19 related costs.

In May of 2020, the PAPUC issued a Secretarial Letter authorizing the creation of regulatory assets to track incremental credit loss expense related
to COVID-19.

The Utility Registrants have also incurred direct costs related to COVID-19 consisting primarily of costs to acquire personal protective equipment, costs for
cleaning supplies and services, and costs to hire healthcare professionals to monitor the health of their employees.

The Utility Registrants have recorded regulatory assets for the impacts of COVID-19 reflecting primarily incremental credit losses and direct costs, partially
offset  by  a  decrease  in  travel  costs  at  BGE  and  PHI.  Refer  to  the  Regulatory  assets  table  above  for  amounts  as  of  December  31,  2020.  The  Utility
Registrants expect to seek recovery in upcoming distribution base rate cases.

Generation Regulatory Matters (Exelon and Generation)

Illinois Regulatory Matters

Zero Emission Standard. Pursuant to FEJA, on January 25, 2018, the ICC announced that Generation’s Clinton Unit 1, Quad Cities Unit 1, and Quad Cities
Unit 2 nuclear plants were selected as the winning bidders through the IPA's ZEC procurement event.

Generation executed the ZEC procurement contracts with Illinois utilities, including ComEd, effective January 26, 2018 and began recognizing revenue with
compensation for the sale of ZECs retroactive to the June 1, 2017 effective date of FEJA. The ZEC price was initially established at $16.50 per MWh of
production, subject to annual future adjustments determined by the IPA for specified escalation and pricing adjustment mechanisms designed to lower the
ZEC price based on increases in underlying energy and capacity prices. Illinois utilities are required to purchase all ZECs delivered by the zero-emissions
nuclear-powered generating facilities, subject to annual cost caps. For the initial delivery year, June 1, 2017 to May 31, 2018, and subsequent delivery year,
June 1, 2018 to May 31, 2019, the ZEC annual cost cap was set at $235 million (ComEd’s share is approximately $170 million). For subsequent delivery
years, the IPA-approved targeted ZEC procurement amounts will change based on forward energy and capacity prices. ZECs delivered to Illinois utilities in
excess of the annual cost cap may be paid in subsequent years if the payments do not exceed the prescribed annual cost cap for that year. During the first
quarter of 2018, Generation recognized $150 million of revenue related to ZECs generated from June 1, 2017 through December 31, 2017.

New Jersey Regulatory Matters

New Jersey Clean Energy Legislation. On May 23, 2018, New Jersey enacted legislation that established a ZEC program that provides compensation for
nuclear plants that demonstrate to the NJBPU that they meet certain requirements, including that they make a significant contribution to air quality in the
state  and  that  their  revenues  are  insufficient  to  cover  their  costs  and  risks.  Under  the  legislation,  the  NJBPU  will  issue  ZECs  to  qualifying  nuclear  power
plants and the electric distribution utilities in New Jersey, including ACE, will be required to purchase those ZECs. On April 18, 2019, the NJBPU approved
the award of ZECs to Salem 1 and Salem 2. Upon approval, Generation began recognizing revenue for the sale of New Jersey ZECs in the month they are
generated and has recognized $69 million and $53 million for the year ended December 31, 2020 and 2019, respectively. On May 15, 2019, New Jersey
Rate Counsel appealed the NJBPU's decision to the New Jersey Superior Court. Briefing has been completed, and on December 9, 2020, oral argument
took place. On October 1, 2020, PSEG and Generation filed applications seeking ZECs for the second eligibility period (June 2022 through May 2025). The
NJBPU  will  act  on  the  applications  by  the  end  of  April  2021.  Exelon  and  Generation  cannot  predict  the  outcome  of  the  appeal.  See  Note  7  -  Early  Plant
Retirements for additional information related to Salem.

Note 3 — Regulatory Matters

New York Regulatory Matters

New York Clean Energy Standard. On August 1, 2016, the NYPSC issued an order establishing the New York CES, a component of which is a Tier 3 ZEC
program  targeted  at  preserving  the  environmental  attributes  of  zero-emissions  nuclear-powered  generating  facilities  that  meet  the  criteria  demonstrating
public necessity as determined by the NYPSC to be Generation's FitzPatrick, Ginna, and Nine Mile Point nuclear facilities.

On  November  30,  2016  (as  amended  on  January  13,  2017),  a  group  of  parties  filed  a  Petition  in  New  York  State  court  seeking  to  invalidate  the  ZEC
program, which argued that the NYPSC did not have authority to establish the program, that it violated state environmental law and that it violated certain
technical  provisions  of  the  State  Administrative  Procedures  Act  when  adopting  the  ZEC  program.  On  January  22,  2018,  the  court  dismissed  the
environmental claims and the majority of the plaintiffs from the case but denied the motions to dismiss with respect to the remaining five plaintiffs and claims,
without  commenting  on  the  merits  of  the  case.  On  October  8,  2019,  the  court  dismissed  all  remaining  claims.  The  petitioners  filed  a  notice  of  appeal  on
November 4, 2019 and originally had until May 4, 2020 to file their brief. Due to COVID-19 related restrictions, the court extended the deadline to July 29,
2020. Petitioners did not file a brief by the deadline, so the case is deemed dismissed. Petitioners are permitted up to one year from July 29, 2020 to file a
motion to vacate the dismissal if they can show good cause for the delay.

See Note 7 — Early Plant Retirements for additional information related to Ginna and Nine Mile Point.

New England Regulatory Matters

Mystic Units 8 & 9 and Everett Marine Terminal Cost of Service Agreement (Exelon and Generation). On March 29, 2018, Generation notified grid
operator ISO-NE of its plans to early retire Mystic Units 8 and 9 absent regulatory reforms on June 1, 2022. On May 16, 2018, Generation made a filing with
FERC to establish cost-of-service compensation and terms and conditions of service for Mystic Units 8 & 9 for the period between June 1, 2022 - May 31,
2024. On December 20, 2018, FERC issued an order accepting the cost of service compensation, reflecting a number of adjustments to the annual fixed
revenue  requirement,  and  allowing  for  recovery  of  a  substantial  portion  of  the  costs  associated  with  the  adjacent  Everett  Marine  Terminal  acquired  by
Generation in October 2018. Those adjustments were reflected in a compliance filing made on March 1, 2019. In the December 20, 2018 order, FERC also
directed a paper hearing on ROE using a new methodology. On January 22, 2019, Exelon and several other parties filed requests for rehearing of certain
findings in the order.

On  July  17,  2020,  FERC  issued  three  orders,  which  together  affirmed  the  recovery  of  key  elements  of  Mystic's  cost  of  service  compensation,  including
recovery of costs associated with the operation of the Everett Marine Terminal. FERC directed a downward adjustment to the rate base for Mystic Units 8
and  9,  the  effect  of  which  will  be  partially  offset  by  elimination  of  a  crediting  mechanism  for  third  party  gas  sales  during  the  term  of  the  cost  of  service
agreement. A compliance filing was submitted on September 15, 2020 and is pending. Several parties filed protests to the compliance filing on the issue of
how gross plant in-service was calculated and Generation filed an answer to the protests on October 21, 2020. On July 28, 2020, FERC ordered additional
briefings in the ROE proceeding. On December 21, 2020, FERC issued an order on rehearing of the three July 17, 2020 orders, clarifying several cost of
service provisions.

On August 25, 2020, a group of New England generators filed a complaint against Generation seeking to extend the scope of the claw back provision in the
cost-of-service  agreement,  whereby  Generation  would  refund  certain  amounts  recovered  during  the  term  of  the  cost  of  service  if  it  returns  to  market
afterwards. On September 14, 2020, Generation filed an answer to the complaint arguing that the complaint is procedurally improper and a collateral attack
on  existing  FERC  orders,  and  pointing  out  that  the  ISO-NE  tariff  contains  protections  against  the  New  England  generators'  concerns  that  they  failed  to
mention.  On  September  28,  2020,  New  England  generators  filed  an  answer  to  Generation’s  answer.  Generation  cannot  predict  the  outcome  of  this
proceeding.

On June 10, 2020, Generation filed a complaint with FERC against ISO-NE on the grounds that ISO-NE failed to follow its tariff with respect to its evaluation
of Mystic for transmission security for the 2024 to 2025 Capacity Commitment Period (FCA 15) and that the modifications that ISO-NE made to its unfiled
planning  procedures  to  avoid  retaining  Mystic  should  have  been  filed  with  FERC  for  approval.  On  July  27,  2020,  ISO-NE  issued  a  memo  to  NEPOOL
announcing its determination pursuant to its unfiled planning procedures that Mystic Units 8 and 9 are not needed for FCA 15 for transmission security. It had
previously  determined  Mystic  Units  8  and  9  are  not  needed  for  fuel  security.  On  August  17,  2020,  FERC  issued  an  order  denying  the  complaint.  On
September 16,

2020, Generation filed a request for rehearing with FERC. On October 19, 2020, FERC denied rehearing by operation of law and on December 18, 2020,
Generation appealed to the U.S. Court of Appeals for the D.C. Circuit. The timing and the outcome of this proceeding is uncertain.

See Note 7 — Early Plant Retirements and Note 12 — Asset Impairments for additional information on the impacts of Generation’s August 2020 decision to
retire Mystic Units 8 & 9 upon expiration of the cost of service agreement.

Federal Regulatory Matters

PJM and NYISO MOPR Proceedings. PJM and NYISO capacity markets include a MOPR. If a resource is subjected to a MOPR, its offer is adjusted to
effectively remove the revenues it receives through a state government-provided financial support program - resulting in a higher offer that may not clear the
capacity market. Prior to December 19, 2019, the MOPR in PJM applied only to certain new gas-fired resources. Currently, the MOPR in NYISO applies only
to certain resources in downstate New York.

For  Generation’s  facilities  in  PJM  and  NYISO  that  are  currently  receiving  ZEC  compensation,  an  expanded  MOPR  would  require  exclusion  of  ZEC
compensation when bidding into future capacity auctions, resulting in an increased risk of these facilities not receiving capacity revenues in future auctions.

On December 19, 2019, FERC required PJM to broadly apply the MOPR to all new and existing resources including nuclear, renewables, demand response,
energy efficiency, storage, and all resources owned by vertically-integrated utilities. This greatly expands the breadth and scope of PJM’s MOPR, which is
effective  as  of  PJM’s  next  capacity  auction.  While  FERC  included  some  limited  exemptions,  no  exemptions  were  available  to  state-supported  nuclear
resources.

FERC  provided  no  new  mechanism  for  accommodating  state-supported  resources  other  than  the  existing  FRR  mechanism  (under  which  an  entire  utility
zone would be removed from PJM’s capacity auction along with sufficient resources to support the load in such zone). In response to FERC’s order, PJM
submitted a compliance filing on March 18, 2020 wherein PJM proposed tariff language interpreting and implementing FERC's directives, and proposed a
schedule for resuming capacity auctions that is contingent on the timing of FERC's action on the compliance filing.

On April 16, 2020, FERC issued an order largely denying most requests for rehearing of FERC's December 2019 order but granting a few clarifications that
required an additional PJM compliance filing which PJM submitted on June 1, 2020.

On October 15, 2020, FERC issued an order denying requests for rehearing of its April 16, 2020 order and accepting PJM’s two compliance filings, subject
to  a  further  compliance  filing  to  revise  minor  aspects  of  the  proposed  MOPR  methodology.  As  part  of  that  order,  FERC  also  accepted  PJM’s  proposal  to
condense the schedule of activities leading up to the next capacity auction. In November 2020, PJM announced that it will conduct its next capacity auction
beginning on May 19, 2021 and ending on May 25, 2021 and will post the results on June 2, 2021.

Because  neither  Illinois  nor  New  Jersey  have  implemented  an  FRR  program  in  their  PJM  zones,  the  MOPR  will  apply  in  that  next  capacity  auction  to
Generation's owned or jointly owned nuclear plants in those states receiving a benefit under the Illinois ZES, or the New Jersey ZEC program, as applicable,
increasing the risk that those units may not clear the capacity market.

Exelon is currently working with PJM and other stakeholders to pursue the FRR option as an alternative to the PJM capacity auction. If Illinois implements
the FRR option, Generation’s Illinois nuclear plants could be removed from PJM’s capacity auction and instead supply capacity, and be compensated under
the  FRR  program,  which  has  the  potential  to  mitigate  the  current  economic  distress  being  experienced  by  Generation's  nuclear  plants  in  Illinois,  as
discussed  in  Note  7  —  Early  Plant  Retirements.  Implementing  the  FRR  program  in  Illinois  will  require  both  legislative  and  regulatory  changes.  Whether
legislation is needed in New Jersey would depend on how the state chooses to structure an FRR program. Exelon cannot predict whether or when such
legislative and regulatory changes can be implemented.

Note 3 — Regulatory Matters

On February 20, 2020, FERC issued an order rejecting requests to expand NYISO’s version of the MOPR (referred to as buyer-side mitigation rules) beyond
its  current  limited  applicability  to  certain  resources  in  downstate.  However,  on  October  14,  2020,  two  natural  gas-fired  generators  in  New  York  filed  a
complaint  at  FERC  seeking  to  expand  the  MOPR  in  NYISO  to  apply  to  all  resources,  new  and  existing,  across  the  entire  NYISO  market.  Exelon  is
strenuously opposing expansion of FERC’s MOPR policies in the NYISO market. While it is too early in the proceeding to predict its outcome and there are
significant differences between the NYISO and PJM markets that would justify a different result, if FERC follows its MOPR precedent in PJM and applies the
MOPR in NYISO broadly as requested in the complaint, Generation’s facilities in NYISO that are receiving ZEC compensation may be at increased risk of
not clearing the capacity auction.

If Generation’s state-supported nuclear plants in PJM or NYISO are subjected to the MOPR or equivalent without compensation under an FRR or similar
program,  it  could  have  a  material  adverse  impact  on  Exelon's  and  Generation's  financial  statements,  which  Exelon  and  Generation  cannot  reasonably
estimate at this time.

Operating License Renewals

Conowingo  Hydroelectric  Project.  On  August  29,  2012,  Generation  submitted  a  hydroelectric  license  application  to  FERC  for  a  new  license  for  the
Conowingo Hydroelectric Project (Conowingo). In connection with Generation’s efforts to obtain a water quality certification pursuant to Section 401 of the
Clean  Water  Act  (401  Certification)  from  MDE  for  Conowingo,  Generation  has  been  working  with  MDE  and  other  stakeholders  to  resolve  water  quality
licensing issues, including: (1) water quality, (2) fish habitat, and (3) sediment.

On  April  21,  2016,  Generation  and  the  U.S.  Fish  and  Wildlife  Service  of  the  U.S.  Department  of  the  Interior  executed  a  settlement  agreement  (DOI
Settlement) resolving all fish passage issues between the parties.

On April 27, 2018, MDE issued its 401 Certification for Conowingo. As issued, the 401 Certification contains numerous conditions, including those relating to
reduction of nutrients from upstream sources, removal of all visible trash and debris from upstream sources, and implementation of measures relating to fish
passage, which could have a material, unfavorable impact on Exelon’s and Generation’s financial statements through an increase in capital expenditures
and operating costs if implemented. On May 25, 2018, Generation filed complaints in federal and state court, along with a petition for reconsideration with
MDE,  alleging  that  the  conditions  are  unfair  and  onerous  and  in  violation  of  MDE  regulations  and  state,  federal,  and  constitutional  law.  Generation  also
requested  that  FERC  defer  the  issuance  of  the  federal  license  while  these  significant  state  and  federal  law  issues  are  pending.  On  February  28,  2019,
Generation  filed  a  Petition  for  Declaratory  Order  with  FERC  requesting  that  FERC  issue  an  order  declaring  that  MDE  waived  its  right  to  issue  a  401
Certification  for  Conowingo  because  it  failed  to  timely  act  on  Conowingo’s  401  Certification  application  and  requesting  that  FERC  decline  to  include  the
conditions required by MDE in April 2018.

On  October  29,  2019,  Generation  and  MDE  filed  with  FERC  a  Joint  Offer  of  Settlement  (Offer  of  Settlement)  that  would  resolve  all  outstanding  issues
relating to the 401 Certification. Pursuant to the Offer of Settlement, the parties submitted Proposed License Articles to FERC to be incorporated by FERC
into the new license in accordance with FERC’s discretionary authority under the Federal Power Act. Among the Proposed License Articles are modifications
to river flows to improve aquatic habitat, eel passage improvements, and initiatives to support rare, threatened and endangered wildlife. If FERC approves
the Offer of Settlement and incorporates the Proposed License Articles into the new license without modification, then MDE would waive its rights to issue a
401  Certification  and  Generation  would  agree,  pursuant  to  a  separate  agreement  with  MDE  (MDE  Settlement),  to  implement  additional  environmental
protection, mitigation, and enhancement measures over the anticipated 50-year term of the new license. These measures address mussel restoration and
other ecological and water quality matters, among other commitments. Exelon’s commitments under the various provisions of the Offer of Settlement and
MDE Settlement are not effective unless and until FERC approves the Offer of Settlement, and issues the new license with the Proposed License Articles.

The financial impact of the DOI and MDE Settlements and other anticipated license commitments are estimated to be $11 million to $14 million per year, on
average, recognized over the new license term, including capital and operating costs. The actual timing and amount of the majority of these costs are not
currently  fixed  and  will  vary  from  year  to  year  throughout  the  life  of  the  new  license.  Generation  cannot  currently  predict  when  FERC  will  issue  the  new
license.  As  of  December  31,  2020,  $45  million  of  direct  costs  associated  with  Conowingo  licensing  efforts  have  been  capitalized.  Generation's  current
depreciation provision for Conowingo assumes renewal of the FERC license.

The  Registrants  recognize  revenue  from  contracts  with  customers  to  depict  the  transfer  of  goods  or  services  to  customers  at  an  amount  that  the  entities
expect to be entitled to in exchange for those goods or services. Generation’s primary sources of revenue include competitive sales of power, natural gas,
and  other  energy-related  products  and  services.  The  Utility  Registrants’  primary  sources  of  revenue  include  regulated  electric  and  gas  tariff  sales,
distribution, and transmission services. The performance obligations, revenue recognition, and payment terms associated with these sources of revenue are
further discussed in the table below. There are no significant financing components for these sources of revenue and no variable consideration for regulated
electric and gas tariff sales and regulated transmission services unless noted below.

Unless otherwise noted, for each of the significant revenue categories and related performance obligations described below, the Registrants have the right to
consideration from the customer in an amount that corresponds directly with the value transferred to the customer for the performance completed to date.
Therefore, the Registrants generally recognize revenue in the amount for which they have the right to invoice the customer. As a result, there are generally
no significant judgments used in determining or allocating the transaction price.

__________
(a) Certain contracts may contain limits on the total amount of revenue Exelon and Generation are able to collect over the entire term of the contract. In such cases, Exelon
and Generation estimate the total consideration expected to be received over the term of the contract net of the constraint and allocate the expected consideration to the
performance obligations

in the contract such that revenue is recognized ratably over the term of the entire contract as the performance obligations are satisfied.

(b) The method recognizes revenue based on the various inputs used to satisfy the performance obligation, such as costs incurred and total labor hours expended. The total
amount  of  revenue  that  will  be  recognized  is  based  on  the  agreed  upon  contractually-stated  amount.  The  average  contract  term  for  these  projects  is  approximately  18
months.

(c) Electric and natural gas utility customers have the choice to purchase electricity or natural gas from competitive electric generation and natural gas suppliers. While the
Utility Registrants are required under state legislation to bill their customers for the supply and distribution of electricity and/or natural gas, they recognize revenue related
only to the distribution services when customers purchase their electricity or natural gas from competitive suppliers.

(d) Passage of time is used for NITS and access to the wholesale grid and MWHs of energy transported over the wholesale grid is used for scheduling, system control and

dispatch services.

Generation incurs incremental costs in order to execute certain retail power and gas sales contracts. These costs, which primarily relate to retail broker fees
and  sales  commissions,  are  capitalized  when  incurred  as  contract  acquisition  costs  and  were  immaterial  as  of  December  31,  2020  and  2019.  The  Utility
Registrants do not incur any material costs to obtain or fulfill contracts with customers.

Contract Balances (All Registrants)

Contract Assets

Generation records contract assets for the revenue recognized on the construction and installation of energy efficiency assets and new power generating
facilities before Generation has an unconditional right to bill for and receive the consideration from the customer. These contract assets are subsequently
reclassified  to  receivables  when  the  right  to  payment  becomes  unconditional.  Generation  records  contract  assets  and  contract  receivables  within  Other
current assets and Customer accounts receivable, net, respectively, within Exelon’s and Generation’s Consolidated Balance Sheets.

The following table provides a rollforward of the contract assets reflected in Exelon's and Generation's Consolidated Balance Sheets. The Utility Registrants
do not have any contract assets.

Contract Liabilities

The  Registrants  record  contract  liabilities  when  consideration  is  received  or  due  prior  to  the  satisfaction  of  the  performance  obligations.  The  Registrants
record contract liabilities within Other current liabilities and Other noncurrent liabilities within the Registrants' Consolidated Balance Sheets.

For Generation, these contract liabilities primarily relate to upfront consideration received or due for equipment service plans, solar panel leases, and the
Illinois ZEC program that introduces a cap on the total consideration to be received by Generation. The Generation contract liability related to the Illinois ZEC
program  includes  certain  amounts  with  ComEd  that  are  eliminated  in  consolidation  in  Exelon’s  Consolidated  Statements  of  Operations  and  Consolidated
Balance Sheets.

On  July  1,  2020,  Pepco,  DPL,  and  ACE  each  entered  into  a  collaborative  arrangement  with  an  unrelated  owner  and  manager  of  communication
infrastructure (the Buyer). Under this arrangement, Pepco, DPL, and ACE sold a 60% undivided interest in their respective portfolios of transmission tower
attachment agreements with

telecommunications companies to the Buyer, in addition to transitioning management of the day-to-day operations of the jointly-owned agreements to the
Buyer for 35 years, while retaining the safe and reliable operation of its utility assets. In return, Pepco, DPL, and ACE will provide the Buyer limited access
on the portion of the towers where the equipment resides for the purposes of managing the agreements for the benefit of Pepco, DPL, ACE, and the Buyer.
In addition, for an initial period of three years and two, two-year extensions that are subject to certain conditions, the Buyer has the exclusive right to enter
into new agreements with telecommunications companies and to receive a 30% undivided interest in those new agreements. PHI, Pepco, DPL, and ACE
received  cash  and  recorded  contract  liabilities  as  of  July  1,  2020  as  shown  in  the  table  below.  The  revenue  attributable  to  this  arrangement  will  be
recognized as operating revenue over the 35 years under the collaborative arrangement.

The  following  table  provides  a  rollforward  of  the  contract  liabilities  reflected  in  Exelon's,  Generation's,  PHI's,  Pepco's,  DPL's,  and  ACE'S  Consolidated

Transaction Price Allocated to Remaining Performance Obligations (All Registrants)

The following table shows the amounts of future revenues expected to be recorded in each year for performance obligations that are unsatisfied or partially
unsatisfied as of December 31, 2020. This disclosure only includes contracts for which the total consideration is fixed and determinable at contract inception.
The average contract term varies by customer type and commodity but ranges from one month to several years.

This disclosure excludes Generation's power and gas sales contracts as they contain variable volumes and/or variable pricing. This disclosure also excludes
the Utility Registrants' gas and electric tariff sales contracts and transmission revenue contracts as they generally have an original expected duration of one
year or less and, therefore, do not contain any future, unsatisfied performance obligations to be included in this disclosure.

Revenue Disaggregation (All Registrants)

The Registrants disaggregate revenue recognized from contracts with customers into categories that depict how the nature, amount, timing, and uncertainty
of  revenue  and  cash  flows  are  affected  by  economic  factors.  See  Note  5  —  Segment  Information  for  the  presentation  of  the  Registrant's  revenue
disaggregation.

5. Segment Information (All Registrants)

Operating  segments  for  each  of  the  Registrants  are  determined  based  on  information  used  by  the  CODM  in  deciding  how  to  evaluate  performance  and
allocate resources at each of the Registrants.

Exelon has eleven reportable segments, which include Generation's five reportable segments consisting of the Mid-Atlantic, Midwest, New York, ERCOT,
and all other power regions referred to     collectively as “Other Power Regions” and ComEd, PECO, BGE, and PHI's three reportable segments consisting of
Pepco,  DPL,  and  ACE.  ComEd,  PECO,  BGE,  Pepco,  DPL,  and  ACE  each  represent  a  single  reportable  segment,  and  as  such,  no  separate  segment
information  is  provided  for  these  Registrants.  Exelon,  ComEd,  PECO,  BGE,  Pepco,  DPL,  and  ACE's  CODMs  evaluate  the  performance  of  and  allocate
resources to ComEd, PECO, BGE, Pepco, DPL, and ACE based on net income.

The basis for Generation's reportable segments is the integrated management of its electricity business that is located in different geographic regions, and
largely  representative  of  the  footprints  of  ISO/RTO  and/or  NERC  regions,  which  utilize  multiple  supply  sources  to  provide  electricity  through  various
distribution  channels  (wholesale  and  retail).  Generation's  hedging  strategies  and  risk  metrics  are  also  aligned  to  these  same  geographic  regions.
Descriptions of each of Generation’s five reportable segments are as follows:

• Mid-Atlantic  represents  operations  in  the  eastern  half  of  PJM,  which  includes  New  Jersey,  Maryland,  Virginia,  West  Virginia,  Delaware,  the

District of Columbia, and parts of Pennsylvania and North Carolina.

• Midwest represents operations in the western half of PJM and the United States footprint of MISO, excluding MISO’s Southern Region.

•

•

•

•

•

New York represents operations within NYISO.

ERCOT represents operations within Electric Reliability Council of Texas.

Other Power Regions:

New England represents operations within ISO-NE.

South  represents  operations  in  the  FRCC,  MISO’s  Southern  Region,  and  the  remaining  portions  of  the  SERC  not  included  within  MISO  or
PJM.

• West represents operations in the WECC, which includes CAISO.

•

Canada represents operations across the entire country of Canada and includes AESO, OIESO, and the Canadian portion of MISO.

The  CODMs  for  Exelon  and  Generation  evaluate  the  performance  of  Generation’s  electric  business  activities  and  allocate  resources  based  on  RNF.
Generation  believes  that  RNF  is  a  useful  measurement  of  operational  performance.  RNF  is  not  a  presentation  defined  under  GAAP  and  may  not  be
comparable to other companies’

256

Table of Contents

(Dollars in millions, except per share data unless otherwise noted)

Note 5 — Segment Information

presentations or deemed more useful than the GAAP information provided elsewhere in this report. Generation’s operating revenues include all sales to third
parties  and  affiliated  sales  to  the  Utility  Registrants.  Purchased  power  costs  include  all  costs  associated  with  the  procurement  and  supply  of  electricity
including  capacity, energy, and ancillary services.  Fuel  expense  includes  the  fuel  costs  for  Generation’s  owned  generation  and  fuel  costs  associated  with
tolling  agreements.  The  results  of  Generation's  other  business  activities  are  not  regularly  reviewed  by  the  CODM  and  are  therefore  not  classified  as
operating segments or included in the regional reportable segment amounts. These activities include natural gas, as well as other miscellaneous business
activities that are not significant to Generation's overall operating revenues or results of operations. Further, Generation’s unrealized mark-to-market gains
and  losses  on  economic  hedging  activities  and  its  amortization  of  certain  intangible  assets  and  liabilities  relating  to  commodity  contracts  recorded  at  fair
value from mergers and acquisitions are also excluded from the regional reportable segment amounts. Exelon and Generation do not use a measure of total
assets in making decisions regarding allocating resources to or assessing the performance of these reportable segments.

An analysis and reconciliation of the Registrants’ reportable segment information to the respective information in the consolidated financial statements for the
years ended December 31, 2020, 2019, and 2018 is as follows:

(b)

Includes gross utility tax receipts from customers. The offsetting remittance of utility taxes to the governing bodies is recorded in expenses in the Registrants’ Consolidated
Statements of Operations and Comprehensive Income. See Note 24 — Supplemental Financial Information for additional information on total utility taxes.
Intersegment  revenues  exclude  sales  to  unconsolidated  affiliates.  The  intersegment  profit  associated  with  Generation’s  sale  of  certain  products  and  services  by  and
between Exelon’s segments is not eliminated in consolidation due to the recognition of intersegment profit in accordance with regulatory accounting guidance. For Exelon,
these amounts are included in Operating revenues in the Consolidated Statements of Operations and Comprehensive Income. See Note 25 - Related Party Transactions
for additional information on intersegment revenues.

Includes gross utility tax receipts from customers. The offsetting remittance of utility taxes to the governing bodies is recorded in expenses in the Registrants’ Consolidated

(c)
(d) The  Income  (loss)  before  income  taxes  in  Other  and  Intersegment  Eliminations  have  been  adjusted  by  an  offsetting  $489  million  and  $408  million  in  2019  and  2018,
respectively,  and  Total  assets  amounts  in  Other  and  Intersegment  Eliminations  have  been  adjusted  by  an  offsetting  $5.7  billion  in  2019  for  consistency  with  the  Exelon
consolidating disclosure above.

The following tables disaggregate the Registrants' revenue recognized from contracts with customers into categories that depict how the nature, amount,
timing, and uncertainty of revenue and cash flows are affected by economic factors. For Generation, the disaggregation of revenues reflects Generation's
two  primary  products  of  power  sales  and  natural  gas  sales,  with  further  disaggregation  of  power  sales  provided  by  geographic  region.  For  the  Utility
Registrants,  the  disaggregation  of  revenues  reflects  the  two  primary  utility  services  of  rate-regulated  electric  sales  and  rate-regulated  natural  gas  sales
(where applicable), with further disaggregation of these tariff sales provided by major customer groups. Exelon's disaggregated revenues are consistent with
Generation and the Utility Registrants, but exclude any intercompany revenues.

Sales of Customer Accounts Receivable (Exelon and Generation)

On  April  8,  2020,  NER,  a  bankruptcy  remote,  special  purpose  entity,  which  is  wholly-owned  by  Generation,  entered  into  a  revolving  accounts  receivable
financing arrangement with a number of financial institutions and a commercial paper conduit (the Purchasers) to sell certain customer accounts receivable
(the Facility). The Facility, whose maximum capacity is $750 million, is scheduled to expire on April 7, 2021, unless renewed by the mutual consent of the
parties in accordance with its terms. Under the Facility, NER may sell eligible short-term customer accounts receivable to the Purchasers in exchange for
cash  and  subordinated  interest.  The  transfers  are  reported  as  sales  of  receivables  in  Exelon’s  and  Generation’s  consolidated  financial  statements.  The
subordinated  interest  in  collections  upon  the  receivables  sold  to  the  Purchasers  is  referred  to  as  the  DPP,  which  is  reflected  in  Other  current  assets  on
Exelon’s and Generation’s Consolidated Balance Sheet.

On  April  8,  2020,  Generation  derecognized  and  transferred  approximately  $1.2  billion  of  receivables  at  fair  value  to  the  Purchasers  in  exchange  for
approximately $500 million in cash purchase price and $650 million of DPP. On February 17, 2021, Generation received additional cash of $250 million from
the Purchasers for the remaining capacity in the Facility.

The following table summarizes the impact of the sale of certain receivables:

Generation’s risk of loss following the transfer of accounts receivable is limited to the DPP outstanding. Payment of DPP is not subject to significant risks
other than delinquencies and credit losses on accounts receivable transferred, which have historically been and are expected to be immaterial. Generation
continues to service the receivables sold in exchange for a servicing fee. Generation did not record a servicing asset or liability as the servicing fees were
immaterial.

Note 6 — Accounts Receivable

Generation recognizes the cash proceeds received upon sale in Net cash provided by operating activities in the Consolidated Statement of Cash Flows. The
collection and reinvestment of DPP is recognized in Net cash provided by investing activities of the Consolidated Statement of Cash Flows.

See Note 18 — Fair Value of Financial Assets and Liabilities and Note 23 — Variable Interest Entities for additional information.

Other Purchases and Sales of Customer and Other Accounts Receivables (All Registrants)

Generation is required, under supplier tariffs in ISO-NE, MISO, NYISO, and PJM, to sell customer and other receivables to utility companies, which include
the  Utility  Registrants.  The  Utility  Registrants  are  required,  under  separate  legislation  and  regulations  in  Illinois,  Pennsylvania,  Maryland,  District  of
Columbia,  and  New  Jersey,  to  purchase  certain  receivables  from  alternative  retail  electric  and,  as  applicable,  natural  gas  suppliers  that  participate  in  the
utilities' consolidated billing. The following tables present the total receivables purchased and sold for the year ended December 31, 2020.

7. Early Plant Retirements (Exelon and Generation)

Exelon and Generation continuously evaluate factors that affect the current and expected economic value of Generation’s plants, including, but not limited to:
market  power  prices,  results  of  capacity  auctions,  potential  legislative  and  regulatory  solutions  to  ensure  plants  are  fairly  compensated  for  benefits  they
provide through their carbon-free emissions, reliability, or fuel security, and the impact of potential rules from the EPA requiring reduction of carbon and other
emissions  and the efforts of states to implement  those  final  rules.  The  precise  timing  of  an  early  retirement  date  for  any  plant,  and  the  resulting  financial
statement impacts, may be affected by many factors, including the status of potential regulatory or legislative solutions, results of any transmission system
reliability study assessments, the nature of any co-owner requirements and stipulations, and NDT fund requirements for nuclear plants, among other factors.
However, the earliest retirement date for any plant would usually be the first year in which the unit does not have capacity or other obligations, and where
applicable, just prior to its next scheduled nuclear refueling outage.

Nuclear Generation

In 2015 and 2016, Generation identified the Clinton and Quad Cities nuclear plants in Illinois, Ginna and Nine Mile Point nuclear plants in New York, and TMI
nuclear plant in Pennsylvania as having the greatest risk of early retirement based on economic valuation and other factors. In 2017, PSEG made public
similar  financial  challenges  facing  its  New  Jersey  nuclear  plants,  including  Salem,  of  which  Generation  owns  a  42.59%  ownership  interest.  PSEG  is  the
operator of Salem and also has the decision-making authority to retire Salem.

Assuming the continued effectiveness of the Illinois ZES, New Jersey ZEC program, and the New York CES, Generation and CENG, through its ownership
of  Ginna  and  Nine  Mile  Point,  no  longer  consider  Clinton,  Quad  Cities,  Salem,  Ginna,  or  Nine  Mile  Point  to  be  at  heightened  risk  for  early  retirement.
However, to the extent the Illinois ZES, New Jersey ZEC program, or the New York CES do not operate as expected over their full terms,

269

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 7 — Early Plant Retirements

each  of  these  plants,  in  addition  to  FitzPatrick,  would  be  at  heightened  risk  for  early  retirement,  which  could  have  a  material  impact  on  Exelon’s  and
Generation’s future financial statements. In addition, FERC’s December 19, 2019 order on the MOPR in PJM may undermine the continued effectiveness of
the Illinois ZES and the New Jersey ZEC program unless Illinois and New Jersey implement an FRR mechanism under which the Generation plants in these
states would be removed from PJM’s capacity auction. See Note 3 — Regulatory Matters for additional information on the Illinois ZES, New Jersey ZEC
program, New York CES, and FERC's December 19, 2019 order on the MOPR in PJM.

In Pennsylvania, the TMI nuclear plant did not clear in the May 2017 PJM capacity auction for the 2020-2021 planning year, the third consecutive year that
TMI  failed  to  clear  the  PJM  base  residual  capacity  auction  and  on  May  30,  2017,  based  on  these  capacity  auction  results,  prolonged  periods  of  low
wholesale  power  prices,  and  the  absence  of  federal  or  state  policies  that  place  a  value  on  nuclear  energy  for  its  ability  to  produce  electricity  without  air
pollution, Generation announced that it would permanently cease generation operations at TMI. On September 20, 2019, Generation permanently ceased
generation operations at TMI.

Generation’s  Dresden,  Byron,  and  Braidwood  nuclear  plants  in  Illinois  are  also  showing  increased  signs  of  economic  distress,  in  a  market  that  does  not
currently  compensate  them  for  their  unique  contribution  to  grid  resiliency  and  their  ability  to  produce  large  amounts  of  energy  without  carbon  and  air
pollution. The May 2018 PJM capacity auction for the 2021-2022 planning year resulted in the largest volume of nuclear capacity ever not selected in the
auction,  including  all  of  Dresden,  and  portions  of  Byron  and  Braidwood.  While  all  of  LaSalle's  capacity  did  clear  in  the  2021-2022  planning  year  auction,
Generation  has  become  increasingly  concerned  about  the  economic  viability  of  this  plant  as  well  in  a  landscape  where  energy  market  prices  remain
depressed and energy market rules remain fatally flawed.

On  August  27,  2020,  Generation  announced  that  it  intends  to  permanently  cease  generation  operations  at  Byron  in  September  2021  and  at  Dresden  in
November 2021. The current NRC licenses for Byron Units 1 and 2 expire in 2044 and 2046, respectively, and the licenses for Dresden Units 2 and 3 expire
in 2029 and 2031, respectively.

As a result of the decision to early retire Byron and Dresden, Exelon and Generation recognized certain one-time charges for the year ended December 31,
2020 related to materials and supplies inventory reserve adjustments, employee-related costs, including severance benefit costs further discussed below,
and  construction  work-in-progress  impairments,  among  other  items.  In  addition,  as  a  result  of  the  decisions  to  early  retire  Byron  and  Dresden,  there  are
ongoing  annual  financial  impacts  stemming  from  shortening  the  expected  economic  useful  lives  of  these  nuclear  plants  primarily  related  to  accelerated
depreciation  of  plant  assets  (including  any  ARC),  accelerated  amortization  of  nuclear  fuel,  and  changes  in  ARO  accretion  expense  associated  with  the
changes in decommissioning timing and cost assumptions to reflect an earlier retirement date. See Note 10 — Asset Retirement Obligations for additional
information on changes to the nuclear decommissioning ARO balance and Note 12 — Asset Impairments for impairment assessment considerations given to
the Midwest asset group as a result of the early retirement decision. The total impact on Exelon's and Generation's Consolidated Statements of Operations
and Comprehensive Income is summarized in the table below.

(e) For Dresden, reflects the net impacts associated with the remeasurement of the ARO. For TMI, primarily reflects the net impacts associated with the remeasurement of the

ARO. See Note 10 - Asset Retirement Obligations for additional information.

(f) Reflects contractual offset for ARO accretion, ARC depreciation, and net impacts associated with the remeasurement of the ARO. For Byron and Dresden, based on the
regulatory agreement with the ICC, decommissioning-related activities in 2020 have been offset within Exelon's and Generation's Consolidated Statements of Operations
and Comprehensive Income. The offset in 2020 resulted in an equal adjustment to the noncurrent payables to ComEd at Generation and an adjustment to the regulatory
liabilities at ComEd. See Note 10 - Asset Retirement Obligations for additional information.

Severance benefit costs will be provided to employees impacted by the early retirements of Byron and Dresden, to the extent they are not redeployed to
other  nuclear  plants.  For  the  year  ended  December  31,  2020,  Exelon  and  Generation  recorded  severance  expense  of  $81  million  within  Operating  and
maintenance expense in their Consolidated Statements of Operations and Comprehensive Income. The final amount of severance benefit costs will depend
on the specific employees severed.

The following table provides the balance sheet amounts as of December 31, 2020 for Exelon's and Generation's significant assets and liabilities associated
with the Braidwood and LaSalle nuclear plants. Current depreciation provisions are based on the estimated useful lives of these nuclear generating stations,
which reflect the first renewal of the operating licenses.

Exelon continues to work with stakeholders on state policy solutions, while also advocating for broader market reforms at the regional and federal level. The
absence of such solutions or reforms could result in future impairments of the Midwest asset group, or accelerated depreciation for specific plants over their
shortened estimated useful lives, both of which could have a material unfavorable impact on Exelon's and Generation's future results of operations.

Other Generation

In March 2018, Generation notified ISO-NE of its plans to early retire, among other assets, the Mystic Generating Station's units 8 and 9 (Mystic 8 and 9)
absent regulatory reforms to properly value reliability and regional fuel security. Thereafter, ISO-NE identified Mystic 8 and 9 as being needed to ensure fuel
security for the region and entered into a cost of service agreement with these two units for the period between June 1, 2022 - May 31, 2024. The agreement
was approved by the FERC in December 2018.

On June 10, 2020, Generation filed a complaint with FERC against ISO-NE stating that ISO-NE failed to follow its tariff with respect to its evaluation of Mystic
8 and 9 for transmission security for the 2024 to 2025 Capacity Commitment Period (FCA 15) and that the modifications that ISO-NE made to its unfiled
planning procedures to avoid retaining Mystic 8 and 9 should have been filed with FERC for approval. On August 17, 2020, FERC issued an order denying
the complaint. As a result, on August 20, 2020, Exelon determined that Generation will permanently cease generation operations at Mystic 8 and 9 at the
expiration of the cost of service commitment in May 2024. See Note 3 — Regulatory Matters for additional discussion of Mystic’s cost of service agreement.

As  a  result  of  the  decision  to  early  retire  Mystic  8  and  9,  Exelon  and  Generation  recognized  $22  million  of  one-time  charges  for  the  year  ended
December  31,  2020,  related  to  materials  and  supplies  inventory  reserve  adjustments,  among  other  items.  In  addition,  there  are  annual  financial  impacts
stemming from shortening the expected economic useful life of Mystic 8 and 9 primarily related to accelerated depreciation of plant assets.

Average Service Life (years)

Depreciation provisions are based on the estimated useful lives of the stations, which reflect the first renewal of the operating licenses for all of Generation's
operating  nuclear  generating  stations  except  for  Clinton,  Byron,  Dresden,  and  Peach  Bottom.  Clinton  depreciation  provisions  are  based  on  an  estimated
useful life through 2027, which is the last year of the Illinois ZES. Peach Bottom depreciation provisions are based on estimated useful life of 2053 and 2054
for  Unit  2  and  Unit  3,  respectively,  which  reflects  the  second  renewal  of  its  operating  licenses.  Beginning  August  2020,  Byron,  Dresden,  and  Mystic
depreciation provisions were based on their announced shutdown dates of September 2021, November 2021, and May 2024, respectively. See Note 3 —
Regulatory  Matters  for  additional  information  regarding  license  renewals  and  the  Illinois  ZECs  and  Note  7  —  Early  Plant  Retirements  for  additional

Note 10 — Asset Retirement Obligations

10. Asset Retirement Obligations (All Registrants)

Nuclear Decommissioning Asset Retirement Obligations (Exelon and Generation)

Generation  has  a  legal  obligation  to  decommission  its  nuclear  power  plants  following  the  expiration  of  their  operating  licenses.  To  estimate  its
decommissioning  obligation  related  to  its  nuclear  generating  stations  for  financial  accounting  and  reporting  purposes,  Generation  uses  a  probability-
weighted,  discounted  cash  flow  model  which,  on  a  unit-by-unit  basis,  considers  multiple  outcome  scenarios  that  include  significant  estimates  and
assumptions, and are based on decommissioning cost studies, cost escalation rates, probabilistic cash flow models, and discount rates. Generation updates
its  ARO  annually  unless  circumstances  warrant  more  frequent  updates,  based  on  its  review  of  updated  cost  studies  and  its  annual  evaluation  of  cost
escalation  factors  and  probabilities  assigned  to  various  scenarios.  Generation  began  decommissioning  the  TMI  nuclear  plant  upon  permanently  ceasing
operations in 2019. See below section for decommissioning of Zion Station.

The financial statement impact for changes in the ARO, on an individual unit basis, due to the changes in and timing of estimated cash flows generally result
in a corresponding change in the unit’s ARC within Property, plant, and equipment on Exelon’s and Generation’s Consolidated Balance Sheets. If the ARO
decreases  for  a  Non-Regulatory  Agreement  unit  without  any  remaining  ARC,  the  corresponding  change  is  recorded  as  decrease  in  Operating  and
maintenance expense within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income.

The following table provides a rollforward of the nuclear decommissioning ARO reflected in Exelon’s and Generation’s Consolidated Balance Sheets, from
January 1, 2019 to December 31, 2020:

Includes  $80  million  and  $112  million  as  the  current  portion  of  the  ARO  at  December  31,  2020  and  2019,  respectively,  which  is  included  in  Other  current  liabilities  in
Exelon’s and Generation’s Consolidated Balance Sheets.

The net $1,022 million increase in the ARO during 2020 for changes in the amounts and timing of estimated decommissioning cash flows was driven by
multiple adjustments throughout the year. These adjustments primarily include:

•

•

•

A  net  increase  of  approximately  $800  million  was  driven  by  updates  to  Byron  and  Dresden  reflecting  changes  in  assumed  retirement  dates  and
assumed  methods  of  decommissioning  as  a  result  of  the  announcement  to  early  retire  these  plants  in  2021.  Refer  to  Note  7  —  Early  Plant
Retirements for additional information.

An  increase  of  approximately  $360  million  resulting  from  the  change  in  the  assumed  DOE  spent  fuel  acceptance  date  for  disposal  from  2030  to
2035.

A  decrease  of  approximately  $220  million  due  to  lower  estimated  decommissioning  costs  primarily  for  Limerick  and  Peach  Bottom  nuclear  units
resulting from the completion of updated cost studies.

The 2020 ARO updates resulted in a increase of $60 million in Operating and maintenance expense for the year ended December 31, 2020 within Exelon
and Generation's Consolidated Statements of Operations and Comprehensive Income.

Note 10 — Asset Retirement Obligations

The  net  $864  million  increase  in  the  ARO  during  2019  for  changes  in  the  amounts  and  timing  of  estimated  decommissioning  cash  flows  was  driven  by
multiple adjustments throughout the year, some with offsetting impacts. These adjustments primarily include:

•

•

•

An  increase  of  approximately  $780  million  for  changes  in  the  assumed  retirement  timing  probabilities  for  sites  including  certain  economically
challenged nuclear plants and the extension of Peach Bottom’s operating life.

An  increase  of  approximately  $490  million  for  other  impacts  that  included  updated  cost  escalation  rates,  primarily  for  labor,  equipment  and
materials, and current discount rates.

Lower estimated costs to decommission TMI, Nine Mile Point, Ginna, Braidwood, Byron, and LaSalle nuclear units of approximately $410 million
resulting from the completion of updated cost studies.

The 2019 ARO updates resulted in a decrease of $150 million in Operating and maintenance expense for the year ended December 31, 2019 within Exelon
and  Generation's  Consolidated  Statements  of  Operations  and  Comprehensive  Income.  See  Note  7  —  Early  Plant  Retirements  for  additional  information
regarding TMI and economically challenged nuclear plants and Note 3 — Regulatory Matters regarding the Peach Bottom second license renewal.

NDT Funds

NDT  funds  have  been  established  for  each  generation  station  unit  to  satisfy  Generation’s  nuclear  decommissioning  obligations.  Generally,  NDT  funds
established for a particular unit may not be used to fund the decommissioning obligations of any other unit.

The NDT funds associated with Generation's nuclear units have been funded with amounts collected from the previous owners and their respective utility
customers.  PECO  is  authorized  to  collect  funds,  in  revenues,  for  decommissioning  the  former  PECO  nuclear  plants  through  regulated  rates,  and  these
collections are scheduled through the operating lives of the former PECO plants. The amounts collected from PECO customers are remitted to Generation
and deposited into the NDT funds for the unit for which funds are collected. Every five years, PECO files a rate adjustment with the PAPUC that reflects
PECO’s  calculations  of  the  estimated  amount  needed  to  decommission  each  of  the  former  PECO  units  based  on  updated  fund  balances  and  estimated
decommissioning costs. The rate adjustment is used to determine the amount collectible from PECO customers. On March 31, 2017, PECO filed its Nuclear
Decommissioning  Cost  Adjustment  with  the  PAPUC  proposing  an  annual  recovery  from  customers  of  approximately  $4  million.  This  amount  reflects  a
decrease from the previously approved annual collection of approximately $24 million primarily due to the removal of the collections for Limerick Units 1 and
2 as a result of the NRC approving the extension of the operating licenses for an additional 20 years. On August 8, 2017, the PAPUC approved the filing and
the new rates became effective January 1, 2018.

Any shortfall of funds necessary for decommissioning, determined for each generating station unit, is ultimately required to be funded by Generation, with the
exception of a shortfall for the current decommissioning activities at Zion Station, where certain decommissioning activities have been transferred to a third-
party (see Zion Station Decommissioning below) and the CENG units, where any shortfall is required to be funded by both Generation and EDF. Generation,
through PECO, has recourse to collect additional amounts from PECO customers related to a shortfall of NDT funds for the former PECO units, subject to
certain  limitations  and  thresholds,  as  prescribed  by  an  order  from  the  PAPUC.  Generally,  PECO,  and  likewise  Generation  will  not  be  allowed  to  collect
amounts associated with the first $50 million of any shortfall of trust funds compared to decommissioning costs, as well as 5% of any additional shortfalls, on
an aggregate basis for all former PECO units. The initial $50 million and up to 5% of any additional shortfalls would be borne by Generation. No recourse
exists to collect additional amounts from utility customers for any of Generation's other nuclear units. With respect to the former ComEd and PECO units, any
funds remaining in the NDTs after all decommissioning has been completed are required to be refunded to ComEd’s or PECO’s customers, subject to certain
limitations that allow sharing of excess funds with Generation related to the former PECO units. With respect to Generation's other nuclear units, Generation
retains  any  funds  remaining  after  decommissioning.  However,  in  connection  with  CENG's  acquisition  of  the  Nine  Mile  Point  and  Ginna  plants  and
settlements with certain regulatory agencies, CENG is subject to certain conditions pertaining to NDT funds that, if met, could possibly result in obligations to
make payments to certain third parties (clawbacks). For Nine Mile Point and Ginna, the clawback provisions are triggered only in the event

276

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 10 — Asset Retirement Obligations

that the required decommissioning activities are discontinued or not started or completed in a timely manner. In the event that the clawback provisions are
triggered  for  Nine  Mile  Point,  then,  depending  upon  the  triggering  event,  an  amount  equal  to  50%  of  the  total  amount  withdrawn  from  the  funds  for  non-
decommissioning  activities  or  50%  of  any  excess  funds  in  the  trust  funds  above  the  amounts  required  for  decommissioning  (including  spent  fuel
management and decommissioning) is to be paid to the Nine Mile Point sellers. In the event that the clawback provisions are triggered for Ginna, then an
amount equal to any estimated cost savings realized by not completing any of the required decommissioning activities is to be paid to the Ginna sellers.
Generation expects to comply with applicable regulations and timely commence and complete all required decommissioning activities.

At December 31, 2020 and 2019, Exelon and Generation had NDT funds totaling $14,599 million and $13,353 million, respectively. The NDT funds include
$134 million and $163 million for the current portion of the NDT at December 31, 2020 and 2019, respectively, which are included in Other current assets in
Exelon's and Generation's Consolidated Balance Sheets. See Note 24 — Supplemental Financial Information for additional information on activities of the
NDT funds.

Accounting Implications of the Regulatory Agreements with ComEd and PECO

Based on the regulatory agreements with the ICC and PAPUC that dictate Generation’s obligations related to the shortfall or excess of NDT funds necessary
for decommissioning the former ComEd units on a unit-by-unit basis and the former PECO units in total, decommissioning-related activities net of applicable
taxes, including realized and unrealized gains and losses on the NDT funds, depreciation of the ARC, and accretion of the decommissioning obligation, are
generally offset within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income and are recorded by Generation and
the  corresponding  regulated  utility  as  a  component  of  the  intercompany  and  regulatory  balances  on  the  balance  sheet.  For  the  purposes  of  making  this
determination, the decommissioning obligation referred to is different, as described below, from the calculation used in the NRC minimum funding obligation
filings based on NRC guidelines.

For the former PECO units, given the symmetric settlement provisions that allow for continued recovery of decommissioning costs from PECO customers in
the  event  of  a  shortfall  and  the  obligation  for  Generation  to  ultimately  return  any  excess  funds  to  PECO  customers  (on  an  aggregate  basis  for  all  seven
units), decommissioning-related activities are generally offset within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive
Income  regardless  of  whether  the  NDT  funds  are  expected  to  exceed  or  fall  short  of  the  total  estimated  decommissioning  obligation.  The  offset  of
decommissioning-related  activities  within  the  Consolidated  Statement  of  Operations  and  Comprehensive  Income  results  in  an  equal  adjustment  to  the
noncurrent payables or noncurrent receivables to affiliates at Generation with PECO recording an equal noncurrent affiliate receivable from or payable to
Generation and a corresponding regulatory liability or regulatory asset. Any changes to the existing PECO regulatory agreements could impact Exelon’s and
Generation’s  ability  to  offset  decommissioning-related  activities  within  the  Consolidated  Statement  of  Operations  and  Comprehensive  Income,  and  the
impact to Exelon’s and Generation’s financial statements could be material.

For the former ComEd units, given no further recovery from ComEd customers is permitted and Generation retains an obligation to ultimately return any
unused NDTs to ComEd customers (on a unit-by-unit basis), to the extent the related NDT investment balances are expected to exceed the total estimated
decommissioning obligation for each unit, the offset of decommissioning-related activities within the Consolidated Statement of Operations and
Comprehensive Income results with Generation recognizing an intercompany payable to ComEd while ComEd records an intercompany receivable from
Generation with a corresponding regulatory liability. However, given the asymmetric settlement provision that does not allow for continued recovery from
ComEd customers in the event of a shortfall, recognition of a regulatory asset at ComEd is not permissible and accounting for decommissioning-related
activities at Generation for that unit would not be offset, and the impact to Exelon’s and Generation’s Consolidated Statements of Operations and
Comprehensive Income could be material during such periods.

As of December 31, 2020, decommissioning-related activities for all of the former ComEd units, except for Zion (see Zion Station Decommissioning below),
are currently offset within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income.

Note 10 — Asset Retirement Obligations

The decommissioning-related activities related to the Non-Regulatory Agreement Units are reflected in Exelon’s and Generation’s Consolidated Statements
of Operations and Comprehensive Income.

See Note 3 — Regulatory Matters and Note 25 — Related Party Transactions for additional information regarding regulatory liabilities at ComEd and PECO
and intercompany balances between Generation, ComEd, and PECO reflecting the obligation to refund to customers any decommissioning-related assets in
excess of the related decommissioning obligations.

Zion Station Decommissioning

In 2010, Generation completed an ASA under which ZionSolutions assumed responsibility for decommissioning Zion Station and Generation transferred to
ZionSolutions substantially all the Zion Station’s assets, including the related NDT funds.

Following  ZionSolutions'  completion  of  its  contractual  obligations  and  transfer  of  the  NRC  license  to  Generation,  Generation  will  store  the  SNF  at  Zion
Station until it is transferred to the DOE for ultimate disposal, and will complete all remaining decommissioning activities associated with the SNF dry storage
facility.

Generation had retained its obligation for the SNF as well as certain NDT assets to fund its obligation to maintain the SNF at Zion Station until transfer to the
DOE  and  to  complete  all  remaining  decommissioning  activities  for  the  SNF  storage  facility.  Any  shortage  of  funds  necessary  to  maintain  the  SNF  and
decommission the SNF storage facility is ultimately required to be funded by Generation. As of December 31, 2020, the ARO associated with Zion's SNF
storage facility is $175 million and the NDT funds available to fund this obligation are $66 million.

NRC Minimum Funding Requirements

NRC regulations require that licensees of nuclear generating facilities demonstrate reasonable assurance that funds will be available in specified minimum
amounts to decommission the facility at the end of its life. The estimated decommissioning obligations as calculated using the NRC methodology differ from
the ARO recorded in Generation’s and Exelon’s Consolidated Balance Sheets primarily due to differences in the type of costs included in the estimates, the
basis for estimating such costs, and assumptions regarding the decommissioning alternatives to be used, potential license renewals, decommissioning cost
escalation, and the growth rate in the NDT funds. Under NRC regulations, if the minimum funding requirements calculated under the NRC methodology are
less  than  the  future  value  of  the  NDT  funds,  also  calculated  under  the  NRC  methodology,  then  the  NRC  requires  either  further  funding  or  other  financial
guarantees.

Key assumptions used in the minimum funding calculation using the NRC methodology at December 31, 2020 include: (1) consideration of costs only for the
removal of radiological contamination at each unit; (2) the option on a unit-by-unit basis to use generic, non-site specific cost estimates; (3) consideration of
only one decommissioning scenario for each unit; (4) the plants cease operation at the end of their current license lives (with no assumed license renewals
for those units that have not already received renewals); (5) the assumption of current nominal dollar cost estimates that are neither escalated through the
anticipated  period  of  decommissioning,  nor  discounted  using  the  CARFR;  and  (6)  assumed  annual  after-tax  returns  on  the  NDT  funds  of  2%  (3%  for  the
former PECO units, as specified by the PAPUC).

In contrast, the key criteria and assumptions used by Generation to determine the ARO and to forecast the target growth in the NDT funds at December 31,
2020 include: (1) the use of site specific cost estimates that are updated at least once every five years; (2) the inclusion in the ARO estimate of all legally
unavoidable  costs  required  to  decommission  the  unit  (e.g.,  radiological  decommissioning  and  full  site  restoration  for  certain  units,  on-site  spent  fuel
maintenance  and  storage  subsequent  to  ceasing  operations  and  until  DOE  acceptance,  and  disposal  of  certain  LLRW);  (3)  the  consideration  of  multiple
scenarios where decommissioning and site restoration activities, as applicable, are completed under possible scenarios ranging from 10 to 70 years after the
cessation of plant operations; (4) the consideration of multiple end of life scenarios; (5) the measurement of the obligation at the present value of the future
estimated costs and an annual average accretion of the ARO of approximately 4% through a period of approximately 30 years after the end of the extended
lives of the units; and (6) an estimated targeted annual pre-tax return on the NDT funds of 5.6% to 6.1% (as compared to a historical 5-year annual average
pre-tax return of approximately 9.0%).

Note 10 — Asset Retirement Obligations

Generation  is  required  to  provide  to  the  NRC  a  biennial  report  by  unit  (annually  for  units  that  have  been  retired  or  are  within  five  years  of  the  current
approved license life), based on values as of December 31, addressing Generation’s ability to meet the NRC minimum funding levels. Depending on the
value  of  the  trust  funds,  Generation  may  be  required  to  take  steps,  such  as  providing  financial  guarantees  through  letters  of  credit  or  parent  company
guarantees  or  making  additional  contributions  to  the  trusts,  which  could  be  significant,  to  ensure  that  the  trusts  are  adequately  funded  and  that  NRC
minimum funding requirements are met. As a result, Exelon’s and Generation’s cash flows and financial positions may be significantly adversely affected.

Generation filed its biennial decommissioning funding status report with the NRC on April 1, 2019 for all units, including its shutdown units, except for Zion
Station  which  is  included  in  a  separate  report  to  the  NRC  submitted  by  ZionSolutions,  LLC.  The  status  report  demonstrated  adequate  decommissioning
funding  assurance  as  of  December  31,  2018  for  all  units  except  for  Clinton  and  Peach  Bottom  Unit  1.  As  of  February  28,  2019,  Clinton  demonstrated
adequate minimum funding assurance due to market recovery and no further action is required. This demonstration was also included in the April 1, 2019
submittal. On March 31, 2020, Generation filed its annual decommissioning funding status report with the NRC for Generation’s shutdown units (excluding
Zion Station for the reason noted above). The annual status report demonstrated adequate decommissioning funding assurance as of December 31, 2019,
for all of its shutdown reactors except for Peach Bottom Unit 1. As a former PECO plant, financial assurance for decommissioning Peach Bottom Unit 1 is
provided by the NDT fund, collections from PECO ratepayers, and the ability to adjust those collections in accordance with the approved PAPUC tariff. No
additional actions are required aside from the PAPUC filing in accordance with the tariff.

Generation will file its next decommissioning funding status report with the NRC by March 31, 2021. This report will reflect the status of decommissioning
funding  assurance  as  of  December  31,  2020  and  will  include  the  2021  early  retirements  of  Byron  and  Dresden.  A  shortfall  could  require  Exelon  to  post
parental  guarantee  for  Generation’s  share  of  the  funding  assurance.  However,  the  amount  of  any  required  guarantee  will  ultimately  depend  on  the
decommissioning approach adopted at Byron and Dresden, the associated level of costs, and the decommissioning trust fund investment performance going
forward.

As  the  future  values  of  trust  funds  change  due  to  market  conditions,  the  NRC  minimum  funding  status  of  Generation’s  units  will  change.  In  addition,  if
changes occur to the regulatory agreement with the PAPUC that currently allows amounts to be collected from PECO customers for decommissioning the
former PECO units, the NRC minimum funding status of those plants could change at subsequent NRC filing dates.

Non-Nuclear Asset Retirement Obligations (All Registrants)

Generation has AROs for plant closure costs associated with its fossil and renewable generating facilities, including asbestos abatement, removal of certain
storage  tanks,  restoring  leased  land  to  the  condition  it  was  in  prior  to  construction  of  renewable  generating  stations  and  other  decommissioning-related
activities. The Utility Registrants have AROs primarily associated with the abatement and disposal of equipment and buildings contaminated with asbestos
and PCBs. See Note 1 — Significant Accounting Policies for additional information on the Registrants’ accounting policy for AROs.

Note 12 — Asset Impairments

12. Asset Impairments (Exelon and Generation)

The Registrants evaluate the carrying value of long-lived assets or asset groups for recoverability whenever events or changes in circumstances indicate
that  the  carrying  value  of  those  assets  may  not  be  recoverable.  Indicators  of  impairment  may  include  a  deteriorating  business  climate,  including,  but  not
limited to, declines in energy prices, condition of the asset, specific regulatory disallowance, or plans to dispose of a long-lived asset significantly before the
end of its useful life. The Registrants determine if long-lived assets or asset groups are impaired by comparing the undiscounted expected future cash flows
to the carrying value. When the undiscounted cash flow analysis indicates a long-lived asset or asset group is not recoverable, the amount of the impairment
loss  is  determined  by  measuring  the  excess  of  the  carrying  amount  of  the  long-lived  asset  or  asset  group  over  its  fair  value.  The  fair  value  analysis  is
primarily based on the income approach using significant unobservable inputs (Level 3) including revenue and generation forecasts, projected capital and
maintenance  expenditures  and  discount  rates.  A  variation  in  the  assumptions  used  could  lead  to  a  different  conclusion  regarding  the  recoverability  of  an
asset or asset group and, thus, could potentially result in material future impairments of the Registrant's long-lived assets.

Antelope Valley Solar Facility

Generation’s Antelope Valley, a 242 MW solar facility in Lancaster, CA, sells all of its output to PG&E through a PPA. As a result of the PG&E bankruptcy
filing  in  the  first  quarter  of  2019,  Generation  completed  a  comprehensive  review  of  Antelope  Valley's  estimated  undiscounted  future  cash  flows  and  no
impairment charge was recorded.

The  United  States  Bankruptcy  Court  entered  an  order  on  June  20,  2020  confirming  PG&E’s  plan  of  reorganization.  On  July  1,  2020  the  plan  became
effective, and PG&E emerged from bankruptcy. Under the confirmed plan, PG&E will continue to honor the existing PPA agreement with Antelope Valley.

See Note 17 - Debt and Credit Agreements for additional information.

New England Asset Group

During the first quarter of 2018, Mystic Unit 9 did not clear in the ISO-NE capacity auction for the 2021 - 2022 planning year. On March 29, 2018, Generation
notified grid operator ISO-NE of its plans to early retire its Mystic Units 8 and 9 absent regulatory reforms on June 1, 2022. These events suggested that the
carrying value of the New England asset group may be impaired. In the first quarter of 2018, Generation completed a comprehensive review of the estimated
undiscounted future cash flows of the New England asset group and no impairment charge was required.

In the third quarter of 2020, in conjunction with the retirement announcement of Mystic Units 8 and 9, Generation completed a comprehensive review of the
estimated undiscounted future cash flows of the New England asset group and concluded that the estimated undiscounted future cash flows and fair value of
the New England asset group were less than their carrying values. As a result, a pre-tax impairment charge of $500 million was recorded in the third quarter
of 2020 within Operating and maintenance expense in Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income. See
Note 7 - Early Plant Retirements for additional information.

Midwest Asset Group

In  the  third  quarter  of  2020,  in  conjunction  with  the  retirement  announcements  of  the  Byron  and  Dresden  nuclear  plants,  Generation  completed  a
comprehensive review of the estimated undiscounted future cash flows of the Midwest asset group and no impairment charge was required.

Generation  will  continue  to  monitor  the  recoverability  of  the  carrying  value  of  the  Midwest  asset  group  as  certain  other  nuclear  plants  in  Illinois  are  also
showing increased signs of economic distress, which could lead to an early retirement. See Note 7 - Early Plant Retirements for additional information.

Equity Method Investments in Certain Distributed Energy Companies

In  the  third  quarter  of  2019,  Generation’s  equity  method  investments  in  certain  distributed  energy  companies  were  fully  impaired  due  to  an  other-than-
temporary decline in market conditions and underperforming projects.

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 12 — Asset Impairments

Exelon and Generation recorded a pre-tax impairment charge of $164 million in Equity in losses of unconsolidated affiliates and an offsetting pre-tax $96
million  in  Net  income  attributable  to  noncontrolling  interests  in  their  Consolidated  Statements  of  Operations  and  Comprehensive  Income.  As  a  result,
Generation accelerated the amortization of investment tax credits associated with these companies and Exelon and Generation recorded a benefit of $46
million in Income taxes. The impairment charge and the accelerated amortization of investment tax credits resulted in a net $15 million decrease to Exelon’s
and Generation’s earnings. See Note 23 — Variable Interest Entities for additional information.

13. Intangible Assets (Exelon, Generation, ComEd, PHI, Pepco, DPL, and ACE)

Goodwill

The  following  table  presents  the  gross  amount,  accumulated  impairment  loss,  and  carrying  amount  of  goodwill  at  Exelon,  ComEd,  and  PHI  as  of
December 31, 2020 and 2019. There were no additions or impairments during the years ended December 31, 2020 and 2019.

__________
(a) Reflects goodwill recorded in 2000 from the PECO/Unicom merger (predecessor parent company of ComEd).
(b) Reflects goodwill recorded in 2016 from the PHI merger.

Goodwill is not amortized, but is subject to an assessment for impairment at least annually, or more frequently if events occur or circumstances change that
would more likely than not reduce the fair value of ComEd's and PHI's reporting units below their carrying amounts. A reporting unit is an operating segment
or  one  level  below  an  operating  segment  (known  as  a  component)  and  is  the  level  at  which  goodwill  is  assessed  for  impairment.  A  component  of  an
operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and its operating results are
regularly reviewed by segment management. ComEd has a single operating segment. PHI's operating segments are Pepco, DPL, and ACE. See Note 5 —
Segment  Information  for  additional  information.  There  is  no  level  below  these  operating  segments  for  which  operating  results  are  regularly  reviewed  by
segment  management.  Therefore,  the  ComEd,  Pepco,  DPL,  and  ACE  operating  segments  are  also  considered  reporting  units  for  goodwill  impairment
assessment  purposes.  Exelon's  and  ComEd's  $2.6  billion  of  goodwill  has  been  assigned  entirely  to  the  ComEd  reporting  unit,  while  Exelon's  and  PHI's
$4.0  billion  of  goodwill  has  been  assigned  to  the  Pepco,  DPL,  and  ACE  reporting  units  in  the  amounts  of  $2.1  billion,  $1.4  billion,  and  $0.5  billion,
respectively.

Entities assessing goodwill for impairment have the option of first performing a qualitative assessment to determine whether a quantitative assessment is
necessary.  As  part  of  the  qualitative  assessments,  Exelon,  ComEd,  and  PHI  evaluate,  among  other  things,  management's  best  estimate  of  projected
operating  and  capital  cash  flows  for  their  businesses,  outcomes  of  recent  regulatory  proceedings,  changes  in  certain  market  conditions,  including  the
discount rate and regulated utility peer EBITDA multiples, and the passing margin from their last quantitative assessments performed. If an entity bypasses
the  qualitative  assessment,  a  quantitative,  fair  value-based  assessment  is  performed,  which  compares  the  fair  value  of  the  reporting  unit  to  its  carrying
amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, the entity recognizes an impairment charge, which is limited to
the amount of goodwill allocated to the reporting unit.

Application  of  the  goodwill  impairment  assessment  requires  management  judgment,  including  the  identification  of  reporting  units  and  determining  the  fair
value of the reporting unit, which management estimates using a weighted combination of a discounted cash flow analysis and a market multiples analysis.
Significant assumptions used in these fair value analyses include discount and growth rates, utility sector market performance and transactions, projected
operating and capital cash flows for ComEd's, Pepco's, DPL's, and ACE's businesses, and the fair value of debt.

Note 13 — Intangible Assets

2020 and 2019 Goodwill Impairment Assessment. ComEd and PHI qualitatively determined that it was more likely than not that the fair values of their
reporting units exceeded their carrying values and, therefore, did not perform quantitative assessments as of November 1, 2020 and 2019 for ComEd and
PHI. The last quantitative assessments performed were as of November 1, 2016 for ComEd and November 1, 2018 for PHI.

While  the  annual  assessments  indicated  no  impairments,  certain  assumptions  used  to  estimate  reporting  unit  fair  values  are  highly  sensitive  to  changes.
Adverse  regulatory  actions  or  changes  in  significant  assumptions  could  potentially  result  in  future  impairments  of  Exelon's,  ComEd's,  and  PHI’s  goodwill,
which could be material.

Other Intangible Assets and Liabilities

Exelon’s, Generation’s, ComEd’s, and PHI's other intangible assets and liabilities, included in Unamortized energy contract assets and liabilities and Other

Renewable Energy Credits (Exelon and Generation)

Exelon’s  and  Generation’s  RECs  are  included  in  Other  current  assets  and  Other  deferred  debits  and  other  assets  in  the  Consolidated  Balance  Sheets.
Purchased RECs are recorded at cost on the date they are purchased. The cost of RECs purchased on a stand-alone basis is based on the transaction
price, while the cost of RECs acquired through PPAs represents the difference between the total contract price and the market price of energy at contract
inception. Generally, revenue for RECs that are sold to a counterparty under a contract that specifically identifies a power plant is recognized at a point in
time when the power is produced. This includes both bundled and unbundled REC sales. Otherwise, the revenue is recognized upon physical transfer of the
REC to the customer.

__________
(a) Positive percentages represent income tax expense. Negative percentages represent income tax benefit.
(b) At  ComEd,  the  higher  effective  tax  rate  is  primarily  related  to  the  nondeductible  Deferred  Prosecution  Agreement  payments.  See  Note  19  —  Commitments  and

Contingencies for additional information.

(c) At PECO, the negative effective tax rate is primarily related to an increase in plant basis differences attributable to tax repair deductions related to an increase in storms

and qualifying projects.

(d) At BGE, the lower effective tax rate, and at PHI, Pepco, DPL, and ACE, the negative effective tax rate is primarily attributable to accelerated amortization of transmission

related income tax regulatory liabilities as a result of regulatory settlements. See Note 3 — Regulatory Matters for additional information.

__________
(a) Exelon,  Generation,  BGE,  PHI,  Pepco,  and  DPL  decreased  their  unrecognized  state  tax  benefits  primarily  due  to  the  receipt  of  favorable  guidance  with  respect  to  the
deductibility of certain depreciable fixed assets. The recognition of the tax benefits related to BGE, PHI, Pepco, and DPL was offset by corresponding regulatory liabilities
and that portion had no immediate impact to their effective tax rate.

(b) Exelon's  and  Generation's  unrecognized  federal  and  state  tax  benefits  decreased  in  the  first  quarter  of  2020  by  approximately  $411  million  due  to  the  settlement  of  a
federal refund claim with IRS Appeals. The recognition of these tax benefits resulted in an increase to Exelon's and Generation’s net income of $76 million and $73 million,
respectively, in the first quarter of 2020, reflecting a decrease to Exelon's and Generation's income tax expense of $67 million.

Like-Kind Exchange

In 2016, the Tax Court held that Exelon was not entitled to defer a gain on its 1999 like-kind exchange transaction. In addition to the tax and interest related
to the gain deferral, the Tax Court also ruled that Exelon was liable for penalties and interest on the penalties. Exelon had fully paid the amounts assessed
resulting  from the Tax Court decision in 2017. In  September  2017,  Exelon  appealed  the  Tax  Court  decision  to  the  U.S.  Court  of  Appeals  for  the  Seventh
Circuit. In October 2018, the U.S. Court of Appeals for the Seventh Circuit affirmed the

293

Table of Contents

(Dollars in millions, except per share data unless otherwise noted)

Note 14 — Income Taxes

Tax  Court’s  decision.  Exelon  filed  a  petition  seeking  rehearing  of  the  Seventh  Circuit’s  decision,  but  the  Seventh  Circuit  denied  that  petition  in  December
2018. In the first quarter of 2019, Exelon elected not to seek a further review by the U.S. Supreme Court. As a result, Exelon's and ComEd's unrecognized
tax benefits decreased by approximately $33 million and $2 million, respectively, in the first quarter of 2019.

Recognition of unrecognized tax benefits

The following table presents Exelon's, Generation's, and PHI's unrecognized tax benefits that, if recognized, would decrease the effective tax rate. ComEd's,
PECO's, BGE's, Pepco's, DPL's, and ACE's amounts are not material.

__________
(a) PHI has $21 million of unrecognized state tax benefits that, if recognized, $14 million would be in the form of a net operating loss carryforward, which is expected to require

a full valuation allowance based on present circumstances.

ACE has $14 million of unrecognized tax benefits as of December 31, 2020, 2019 and 2018 that, if recognized, may be included in future base rates and that
portion  would  have  no  impact  on  the  effective  tax  rate.  Exelon's,  Generation's,  ComEd's,  PECO's,  BGE's,  PHI's,  Pepco's,  and  DPL's  amounts  are  not
material.

Reasonably possible the total amount of unrecognized tax benefits could significantly increase or decrease within 12 months after the reporting
date

As of December 31, 2020, ACE has approximately $14 million of unrecognized state tax benefits that could significantly decrease within the 12 months after
the reporting date based on the outcome of pending court cases involving other taxpayers. The unrecognized tax benefit, if recognized, may be included in
future base rates and that portion would have no impact to the effective tax rate.

Other Tax Matters

Long-Term Marginal State Income Tax Rate (All Registrants)

Quarterly,  Exelon  reviews  and  updates  its  marginal  state  income  tax  rates  for  changes  in  state  apportionment.  The  Registrants  remeasure  their  existing
deferred  income tax balances to reflect the changes  in  marginal  rates,  which  results  in  either  an  increase  or  a  decrease  to  their  net  deferred  income  tax
liability balances. Utility Registrants record corresponding regulatory liabilities or assets to the extent such amounts are probable of settlement or recovery
through customer rates and an adjustment to income tax expense for all other amounts. The impacts to the Utility Registrants for the years ended December
31, 2020, 2019, and 2018 were not material.

Generation  and  the  Utility  Registrants  are  all  party  to  an  agreement  with  Exelon  and  other  subsidiaries  of  Exelon  that  provides  for  the  allocation  of
consolidated tax liabilities and benefits (Tax Sharing Agreement). The Tax Sharing Agreement provides that each party is allocated an amount of tax similar
to that which would be owed had the party been separately subject to tax. In addition, any net federal and state benefits attributable to Exelon is reallocated
to the other Registrants. That allocation is treated as a contribution to the capital of the party receiving the benefit.

The following table presents the allocation of tax benefits from Exelon under the Tax Sharing Agreement.

Research and Development Activities

In the fourth quarter of 2019, Exelon and Generation recognized additional tax benefits related to certain research and development activities that qualify for
federal and state tax incentives for the 2010 through 2018 tax years, which resulted in an increase to Exelon’s and Generation’s net income of $108 million
and $75 million, respectively, for the year ended December 31, 2019, reflecting a decrease to Exelon’s and Generation’s Income tax expense of $97 million
and $66 million, respectively.

15. Retirement Benefits (All Registrants)

Exelon sponsors defined benefit pension plans and OPEB plans for essentially all current employees. Substantially all non-union employees and electing
union employees hired on or after January 1, 2001 participate in cash balance pension plans. Effective January 1, 2009, substantially all newly-hired union-
represented employees participate in cash balance pension plans. Effective February 1, 2018 for most newly-hired Generation and BSC non-represented,
non-craft,  employees  and  January  1,  2021  for  most  newly-hired  utility  management  employees,  these  newly-hired  employees  are  not  eligible  for  pension
benefits, and will instead be eligible to receive an enhanced non-discretionary employer contribution in an Exelon defined contribution savings plan. Effective
January 1, 2018, most newly-hired non-represented, non-craft, employees are not eligible for OPEB benefits and employees represented by Local 614 are
not  eligible  for  retiree  health  care  benefits.  Effective  January  1,  2021,  most  non-represented,  non-craft,  employees  who  are  under  the  age  of  40  are  not
eligible for retiree health care benefits.

Effective  January  1,  2019,  Exelon  merged  the  Exelon  Corporation  Cash  Balance  Pension  Plan  (CBPP)  into  the  Exelon  Corporation  Retirement  Program
(ECRP).  The  merging  of  the  plans  did  not  change  the  benefits  offered  to  the  plan  participants  and,  thus,  had  no  impact  on  Exelon's  pension  obligation.
However, beginning in 2019, actuarial losses and gains related to the CBPP and ECRP are amortized over participants’ average remaining service period of
the merged ECRP rather than each individual plan.

Exelon’s  traditional  and  cash  balance  pension  plans  are  intended  to  be  tax-qualified  defined  benefit  plans.  Exelon  has  elected  that  the  trusts  underlying
these plans be treated as qualified trusts under the IRC. If certain conditions are met, Exelon can deduct payments made to the qualified trusts, subject to
certain IRC limitations.

Benefit Obligations, Plan Assets, and Funded Status

During the first quarter of 2020, Exelon received an updated valuation of its pension and OPEB to reflect actual census data as of January 1, 2020. This
valuation  resulted  in  an  increase  to  the  pension  and  OPEB  obligations  of  $8  million  and  $31  million,  respectively.  Additionally,  accumulated  other
comprehensive  loss  increased  by  $7  million  (after-tax)  and  regulatory  assets  and  liabilities  increased  by  $19  million  and  decreased  by  $10  million,
respectively.

Components of Net Periodic Benefit Costs

The  majority  of  the  2020  pension  benefit  cost  for  the  Exelon-sponsored  plans  is  calculated  using  an  expected  long-term  rate  of  return  on  plan  assets  of
7.00% and a discount rate of 3.34%. The majority of the 2020 OPEB cost is calculated using an expected long-term rate of return on plan assets of 6.69%
for funded plans and a discount rate of 3.31%.

A portion of the net periodic benefit cost for all plans is capitalized within the Consolidated Balance Sheets. The following table presents the components of
Exelon’s net periodic benefit costs, prior to capitalization, for the years ended December 31, 2020, 2019, and 2018.

Cost Allocation to Exelon Subsidiaries

All Registrants account for their participation in Exelon’s pension and OPEB plans by applying multi-employer accounting. Exelon allocates costs related to
its pension and OPEB plans to its subsidiaries based on both active and retired employee participation in each plan.

The  amounts  below  represent  the  Registrants'  allocated  pension  and  OPEB  costs.  For  Exelon,  the  service  cost  component  is  included  in  Operating  and
maintenance expense and Property, plant, and equipment, net while the non-service cost components are included in Other, net and Regulatory assets. For
Generation and the Utility Registrants, the service cost and non-service cost components are included in Operating and maintenance expense and Property,
plant, and equipment, net in their consolidated financial statements.

offsetting entries to AOCI and regulatory assets (liabilities). A portion of current year actuarial (gains) losses and prior service costs (credits) is capitalized
within Exelon’s Consolidated Balance Sheets to reflect the expected regulatory recovery of these amounts, which would otherwise be recorded to AOCI. The
following tables provide the components of AOCI and regulatory assets (liabilities) for Exelon for the years ended December 31, 2020, 2019, and 2018 for all

Assumptions

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 15 — Retirement Benefits

The measurement of the plan obligations and costs of providing benefits under Exelon’s defined benefit and OPEB plans involves various factors, including
the  development  of  valuation  assumptions  and  inputs  and  accounting  policy  elections.  The  measurement  of  benefit  obligations  and  costs  is  impacted  by
several assumptions and inputs, as shown below, among other factors. When developing the required assumptions, Exelon considers historical information
as well as future expectations.

Expected Rate of Return. In determining the EROA, Exelon considers historical economic indicators (including inflation and GDP growth) that impact asset
returns, as well as expectations regarding future long-term capital market performance, weighted by Exelon’s target asset class allocations.

Mortality. The mortality assumption is composed of a base table that represents the current expectation of life expectancy of the population adjusted by an
improvement scale that attempts to anticipate future improvements in life expectancy. For the year ended December 31, 2020, Exelon’s mortality assumption
utilizes the SOA 2019 base table (Pri-2012) and MP-2020 improvement scale adjusted to use Proxy SSA ultimate improvement rates. For the year ended
December 31, 2019, Exelon's mortality assumption utilizes the SOA 2019 base table (Pri-2012) and MP-2019 improvement scale adjusted to a 0.75% long-
term rate reached in 2035.

For Exelon, the following assumptions were used to determine the benefit obligations for the plans at December 31, 2020 and 2019. Assumptions used to
determine year-end benefit obligations are the assumptions used to estimate the subsequent year’s net periodic benefit costs.

(a) The  discount  rates  above  represent  the  blended  rates  used  to  determine  the  majority  of  Exelon’s  pension  and  OPEB  obligations.  Certain  benefit  plans  used  individual
rates, which range from 2.11% - 2.73% and 2.45% - 2.63% for pension and OPEB plans, respectively, as of December 31, 2020 and 3.02% - 3.44% and 3.27% - 3.40% for

Management considers various factors when making pension funding decisions, including actuarially determined minimum contribution requirements under
ERISA, contributions required to avoid benefit restrictions and at-risk status as defined by the Pension Protection Act of 2006 (the Act), management of the
pension obligation, and regulatory implications. The Act requires the attainment of certain funding levels to avoid benefit restrictions (such as an inability to
pay lump sums or to accrue benefits prospectively), and at-risk status (which triggers higher minimum contribution requirements and participant notification).
The projected contributions below reflect a funding strategy to make levelized annual contributions with the objective of achieving 100% funded status on an
ABO basis over time. This level funding strategy helps minimize volatility of future period required pension contributions. Based on this funding strategy and
current market conditions, which are subject to change,

Note 15 — Retirement Benefits

Exelon’s  estimated  annual  qualified  pension  contributions  will  be  approximately  $500  million  in  2021.  Unlike  the  qualified  pension  plans,  Exelon’s  non-
qualified pension plans are not funded, given that they are not subject to statutory minimum contribution requirements.

While OPEB plans are also not subject to statutory minimum contribution requirements, Exelon does fund certain of its plans. For Exelon's funded OPEB
plans, contributions generally equal accounting costs, however, Exelon’s management has historically considered several factors in determining the level of
contributions to its OPEB plans, including liabilities management, levels of benefit claims paid, and regulatory implications (amounts deemed prudent to meet
regulatory expectations and best assure continued rate recovery). The amounts below include benefit payments related to unfunded plans.

The following table provides all Registrants' planned contributions to the qualified pension plans, planned benefit payments to non-qualified pension plans,
and planned contributions to OPEB plans in 2021:

Investment Strategy. On a regular basis, Exelon evaluates its investment strategy to ensure that plan assets will be sufficient to pay plan benefits when due.
As part of this ongoing evaluation, Exelon may make changes to its targeted asset allocation and investment strategy.

Exelon has developed and implemented a liability hedging investment strategy for its qualified pension plans that has reduced the volatility of its pension
assets  relative  to  its  pension  liabilities.  Exelon  is  likely  to  continue  to  gradually  increase  the  liability  hedging  portfolio  as  the  funded  status  of  its  plans
improves. The overall objective is to achieve attractive risk-adjusted returns that will balance the liquidity requirements of the plans’ liabilities while striving to
minimize  the  risk  of  significant  losses.  Trust  assets  for  Exelon’s  OPEB  plans  are  managed  in  a  diversified  investment  strategy  that  prioritizes  maximizing
liquidity and returns while minimizing asset volatility.

Actual  asset  returns  have  an  impact  on  the  costs  reported  for  the  Exelon-sponsored  pension  and  OPEB  plans.  The  actual  asset  returns  across  Exelon’s
pension  and  OPEB  plans  for  the  year  ended  December  31,  2020  were  14.45%  and  9.14%,  respectively,  compared  to  an  expected  long-term  return
assumption of 7.00% and 6.69%,

respectively. Exelon used an EROA of 7.00% and 6.46% to estimate its 2021 pension and OPEB costs, respectively.

Concentrations of Credit Risk. Exelon evaluated its pension and OPEB plans’ asset portfolios for the existence of significant concentrations of credit risk as
of  December  31,  2020.  Types  of  concentrations  that  were  evaluated  include,  but  are  not  limited  to,  investment  concentrations  in  a  single  entity,  type  of
industry,  foreign  country,  and  individual  fund.  As  of  December  31,  2020,  there  were  no  significant  concentrations  (defined  as  greater  than  10%  of  plan
assets) of risk in Exelon’s pension and OPEB plan assets.

Valuation Techniques Used to Determine Fair Value

The techniques used to fair value the pension and OPEB assets invested in cash equivalents, equities, fixed income, derivatives, private equity, real estate,
and private credit investments are the same as the valuation techniques for these types of investments in NDTFs. See Cash Equivalents and NDT Fund
Investments in Note 18 - Fair Value of Financial Assets and Liabilities for further information.

Pension  and  OPEB  assets  also  include  investments  in  hedge  funds.  Hedge  fund  investments  include  those  that  employ  a  broad  range  of  strategies  to
enhance returns and provide additional diversification. The fair value of

307

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 15 — Retirement Benefits

hedge funds is determined using NAV or its equivalent as a practical expedient, and therefore, hedge funds are not classified within the fair value hierarchy.
Exelon has the ability to redeem these investments at NAV or its equivalent subject to certain restrictions which may include a lock-up period or a gate.

Defined Contribution Savings Plan (All Registrants)

The  Registrants  participate  in  various  401(k)  defined  contribution  savings  plans  that  are  sponsored  by  Exelon.  The  plans  are  qualified  under  applicable
sections  of  the  IRC  and  allow  employees  to  contribute  a  portion  of  their  pre-tax  and/or  after-tax  income  in  accordance  with  specified  guidelines.  All
Registrants match a percentage of the employee contributions up to certain limits. The following table presents matching contributions to the savings plan for

16. Derivative Financial Instruments (All Registrants)

The  Registrants  use  derivative  instruments  to  manage  commodity  price  risk,  interest  rate  risk,  and  foreign  exchange  risk  related  to  ongoing  business
operations.

Authoritative  guidance  requires  that  derivative  instruments  be  recognized  as  either  assets  or  liabilities  at  fair  value,  with  changes  in  fair  value  of  the
derivative  recognized  in  earnings  immediately.  Other  accounting  treatments  are  available  through  special  election  and  designation,  provided  they  meet
specific, restrictive criteria both at the time of designation and on an ongoing basis. These alternative permissible accounting treatments include NPNS, cash
flow  hedges,  and  fair  value  hedges.  All  derivative  economic  hedges  related  to  commodities,  referred  to  as  economic  hedges,  are  recorded  at  fair  value
through  earnings  at  Generation  and  are  offset  by  a  corresponding  regulatory  asset  or  liability  at  ComEd.  For  all  NPNS  derivative  instruments,  accounts
receivable  or  accounts  payable  are  recorded  when  derivative  settles  and  revenue  or  expense  is  recognized  in  earnings  as  the  underlying  physical
commodity is sold or consumed.

Authoritative  guidance  about  offsetting  assets  and  liabilities  requires  the  fair  value  of  derivative  instruments  to  be  shown  in  the  Combined  Notes  to
Consolidated Financial Statements on a gross basis, even when the derivative instruments are subject to legally enforceable master netting agreements and
qualify for net presentation in the Consolidated Balance Sheets. A master netting agreement is an agreement between two counterparties that may have
derivative  and  non-derivative  contracts  with  each  other  providing  for  the  net  settlement  of  all  referenced  contracts  via  one  payment  stream,  which  takes
place as the contracts deliver, when collateral is requested or in the event of default. In the tables below, which present fair value balances, Generation’s
energy-related  economic  hedges  and  proprietary  trading  derivatives  are  shown  gross.  The  impact  of  the  netting  of  fair  value  balances  with  the  same
counterparty that are subject to legally enforceable master netting agreements, as well as netting of cash collateral, including margin on exchange positions,
is aggregated in the collateral and netting columns.

Generation’s  and  ComEd’s  use  of  cash  collateral  is  generally  unrestricted  unless  Generation  or  ComEd  are  downgraded  below  investment  grade.  Cash
collateral held by PECO, BGE, Pepco, DPL, and ACE must be deposited in an unaffiliated major U.S. commercial bank or foreign bank with a U.S. branch
office that meet certain qualifications.

Commodity Price Risk (All Registrants)

Each  of  the  Registrants  employ  established  policies  and  procedures  to  manage  their  risks  associated  with  market  fluctuations  in  commodity  prices  by
entering into physical and financial derivative contracts, including swaps, futures, forwards, options, and short-term and long-term commitments to purchase
and  sell  energy  and  commodity  products.  The  Registrants  believe  these  instruments,  which  are  either  determined  to  be  non-derivative  or  classified  as
economic hedges, mitigate exposure to fluctuations in commodity prices.

308

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 16 — Derivative Financial Instruments

Generation. To the extent the amount of energy Generation produces differs from the amount of energy it has contracted to sell, Exelon and Generation are
exposed  to  market  fluctuations  in  the  prices  of  electricity,  fossil  fuels,  and  other  commodities.  Within  Exelon,  Generation  has  the  most  exposure  to
commodity  price  risk.  As  such,  Generation  uses  a  variety  of  derivative  and  non-derivative  instruments  to  manage  the  commodity  price  risk  of  its  electric
generation  facilities,  including  power  and  gas  sales,  fuel  and  power  purchases,  natural  gas  transportation  and  pipeline  capacity  agreements,  and  other
energy-related  products  marketed  and  purchased.  To  manage  these  risks,  Generation  may  enter  into  fixed-price  derivative  or  non-derivative  contracts  to
hedge the variability in future cash flows from expected sales of power and gas and purchases of power and fuel. The objectives for executing such hedges
include  fixing  the  price  for  a  portion  of  anticipated  future  electricity  sales  at  a  level  that  provides  an  acceptable  return.  Generation  is  also  exposed  to
differences between the locational settlement prices of certain economic hedges and the hedged generating units. This price difference is actively managed
through other instruments which include derivative congestion products, whose changes in fair value are recognized in earnings each period, and auction
revenue rights, which are accounted for on an accrual basis.

Additionally, Generation is exposed to certain market  risks  through  its  proprietary  trading  activities.  The  proprietary  trading  activities  are  a  complement  to
Generation’s energy marketing portfolio but represent a small portion of Generation’s overall energy marketing activities and are subject to limits established
by Exelon’s RMC.

Utility Registrants. The  Utility  Registrants  procure  electric  and  natural  gas  supply  through  a  competitive  procurement  process  approved  by  each  of  the
respective state utility commissions. The Utility Registrants’ hedging programs are intended to reduce exposure to energy and natural gas price volatility and
have  no  direct  earnings  impact  as  the  costs  are  fully  recovered  from  customers  through  regulatory-approved  recovery  mechanisms.  The  following  table
provides a summary of the Utility Registrants’ primary derivative hedging instruments, listed by commodity and accounting treatment.

(a) Exelon and Generation net all available amounts allowed under the derivative authoritative guidance in the balance sheet. These amounts include unrealized derivative
transactions with the same counterparty under legally enforceable master netting agreements and cash collateral. In some cases Exelon and Generation may have other
offsetting exposures, subject to a master netting or similar agreement, such as trade receivables and payables, transactions that do not qualify as derivatives, letters of
credit, and other forms of non-cash collateral. These amounts are not material and not reflected in the table above.

(b) Of the collateral posted, $209 million and $511 million represents variation margin on the exchanges at December 31, 2020 and 2019, respectively.

Economic Hedges (Commodity Price Risk)

Generation. For  the  years  ended  December  31,  2020,  2019,  and  2018,  Exelon  and  Generation  recognized  the  following  net  pre-tax  commodity  mark-to-
market gains (losses) which are also located in the Net fair value changes related to derivatives line in the Consolidated Statements of Cash Flows.

In  general,  increases  and  decreases  in  forward  market  prices  have  a  positive  and  negative  impact,  respectively,  on  Generation’s  owned  and  contracted
generation positions that have not been hedged. Generation hedges commodity price risk on a ratable basis over three-year periods. As of December 31,
2020, the percentage of expected generation hedged for the Mid-Atlantic, Midwest, New York, and ERCOT reportable segments is 94%-97% for 2021.

Proprietary Trading (Commodity Price Risk)

Generation  also  executes  commodity  derivatives  for  proprietary  trading  purposes.  Proprietary  trading  includes  all  contracts  executed  with  the  intent  of
benefiting from shifts or changes in market prices as opposed to those executed with the intent of hedging or managing risk. Gains and losses associated
with  proprietary  trading  are  reported  as  Operating  revenues  in  Exelon’s  and  Generation’s  Consolidated  Statements  of  Operations  and  Comprehensive
Income  and  are  included  in  the  Net  fair  value  changes  related  to  derivatives  line  in  the  Consolidated  Statements  of  Cash  Flows.  For  the  years  ended
December  31,  2020,  2019,  and  2018,  net  pre-tax  commodity  mark-to-market  gains  and  losses  for  Exelon  and  Generation  were  not  material.  The  Utility
Registrants do not execute derivatives for proprietary trading purposes.

Interest Rate and Foreign Exchange Risk (Exelon and Generation)

Exelon and Generation utilize interest rate swaps, which are treated as economic hedges, to manage their interest rate exposure. On July 1, 2018, Exelon
de-designated its fair value hedges related to interest rate risk and Generation de-designated its cash flow hedges related to interest rate risk. The notional
amounts were $516 million and $1,269 million at December 31, 2020 and 2019, respectively, for Exelon and $516 million and $569 million at December 31,
2020 and 2019, respectively, for Generation.

Generation utilizes foreign currency derivatives to manage foreign exchange rate exposure associated with international commodity purchases in currencies
other than U.S. dollars, which are treated as economic hedges. The notional amounts were $149 million and $231 million at December 31, 2020 and 2019,
respectively.

The  mark-to-market  derivative  assets  and  liabilities  as  of  December  31,  2020  and  2019  and  the  mark-to-market  gains  and  losses  for  the  years  ended
December 31, 2020, 2019, and 2018 were not material for Exelon and Generation.

Credit Risk (All Registrants)

The Registrants would be exposed to credit-related losses in the event of non-performance by counterparties on executed derivative instruments. The credit
exposure of derivative contracts, before collateral, is represented by the fair value of contracts at the reporting date.

Generation. For commodity derivatives, Generation enters into enabling agreements that allow for payment netting with its counterparties, which reduces
Generation’s  exposure  to  counterparty  risk  by  providing  for  the  offset  of  amounts  payable  to  the  counterparty  against  amounts  receivable  from  the
counterparty.  Typically,  each  enabling  agreement  is  for  a  specific  commodity  and  so,  with  respect  to  each  individual  counterparty,  netting  is  limited  to
transactions  involving  that  specific  commodity  product,  except  where  master  netting  agreements  exist  with  a  counterparty  that  allow  for  cross  product
netting. In addition to payment netting language in the enabling agreement, Generation’s credit department establishes credit limits, margining thresholds
and  collateral  requirements  for  each  counterparty,  which  are  defined  in  the  derivative  contracts.  Counterparty  credit  limits  are  based  on  an  internal  credit
review  process  that  considers  a  variety  of  factors,  including  the  results  of  a  scoring  model,  leverage,  liquidity,  profitability,  credit  ratings  by  credit  rating
agencies,  and  risk  management  capabilities.  To  the  extent  that  a  counterparty’s  margining  thresholds  are  exceeded,  the  counterparty  is  required  to  post
collateral  with  Generation  as  specified  in  each  enabling  agreement.  Generation’s  credit  department  monitors  current  and  forward  credit  exposure  to
counterparties and their affiliates, both on an individual and an aggregate basis.

Note 16 — Derivative Financial Instruments

The following tables provide information on Generation’s credit exposure for all derivative instruments, NPNS, and payables and receivables, net of collateral
and instruments that are subject to master netting agreements, as of December 31, 2020. The tables further delineate that exposure by credit rating of the
counterparties  and  provide  guidance  on  the  concentration  of  credit  risk  to  individual  counterparties.  The  figures  in  the  tables  below  exclude  credit  risk
exposure from individual retail counterparties, nuclear fuel procurement contracts, and exposure through RTOs, ISOs, NYMEX, ICE, NASDAQ, NGX, and
Nodal commodity exchanges.

__________
(a) As of December 31, 2020, credit collateral held from counterparties where Generation had credit exposure included $31 million of cash and $25 million of letters of credit.

The credit collateral does not include non-liquid collateral.

Utility  Registrants.  The  Utility  Registrants  have  contracts  to  procure  electric  and  natural  gas  supply  that  provide  suppliers  with  a  certain  amount  of
unsecured credit. If the exposure on the supply contract exceeds the amount of unsecured credit, the suppliers may be required to post collateral. The net
credit exposure is mitigated primarily by the ability to recover procurement costs through customer rates. As of December 31, 2020, the Utility Registrants’
counterparty credit risk with suppliers was not material.

Credit-Risk-Related Contingent Features (All Registrants)

Generation. As part of the normal course of business, Generation routinely enters into physically or financially settled contracts for the purchase and sale of
electric capacity, electricity, fuels, emissions allowances, and other energy-related products. Certain of Generation’s derivative instruments contain provisions
that require Generation to post collateral. Generation also enters into commodity transactions on exchanges where the exchanges act as the counterparty to
each trade. Transactions on the exchanges must adhere to comprehensive collateral and margining requirements. This collateral may be posted in the form
of cash or credit support with thresholds contingent upon Generation’s credit rating from each of the major credit rating agencies. The collateral and credit
support requirements vary by contract and by counterparty. These credit-risk related contingent features stipulate that if Generation were to be downgraded
or lose its investment grade credit rating (based on its senior unsecured debt rating), it would be required to provide additional collateral. This incremental
collateral requirement allows for the offsetting of derivative instruments that are assets with the same counterparty, where the contractual right of offset exists
under  applicable master netting agreements. In  the  absence  of  expressly  agreed-to  provisions  that  specify  the  collateral  that  must  be  provided,  collateral
requested will be a function of the facts and circumstances of the situation at the time of the demand. In this case, Generation believes an amount of several
months of future payments (i.e., capacity payments) rather than a calculation of fair value is the best estimate for the contingent collateral obligation, which
has been factored into the disclosure below.

(a) Amount  represents  the  gross  fair  value  of  out-of-the-money  derivative  contracts  containing  credit-risk-related  contingent  features  ignoring  the  effects  of  master  netting

agreements.

(b) Amount  represents  the  offsetting  fair  value  of  in-the-money  derivative  contracts  under  legally  enforceable  master  netting  agreements  with  the  same  counterparty,  which

reduces the amount of any liability for which Generation could potentially be required to post collateral.

(c) Amount  represents  the  net  fair  value  of  out-of-the-money  derivative  contracts  containing  credit-risk  related  contingent  features  after  considering  the  mitigating  effects  of

offsetting positions under master netting arrangements and reflects the actual net liability upon which any potential contingent collateral obligations would be based.

As  of  December  31,  2020  and  2019,  Exelon  and  Generation  posted  or  held  the  following  amounts  of  cash  collateral  and  letters  of  credit  on  derivative
contracts with external counterparties, after giving consideration to offsetting derivative and non-derivative positions under master netting agreements.

Generation entered into supply forward contracts with certain utilities, including PECO and BGE, with one-sided collateral postings only from Generation. If
market  prices  fall  below  the  benchmark  price  levels  in  these  contracts,  the  utilities  are  not  required  to  post  collateral.  However,  when  market  prices  rise
above  the  benchmark  price  levels,  counterparty  suppliers,  including  Generation,  are  required  to  post  collateral  once  certain  unsecured  credit  limits  are
exceeded.

Utility Registrants

The Utility Registrants’ electric supply procurement contracts do not contain provisions that would require them to post collateral.

PECO’s, BGE’s, and DPL’s natural gas procurement contracts contain provisions that could require PECO, BGE, and DPL to post collateral in the form of
cash  or  credit  support,  which  vary  by  contract  and  counterparty,  with  thresholds  contingent  upon  PECO’s,  BGE's,  and  DPL’s  credit  rating.  As  of
December 31, 2020, PECO, BGE, and DPL were not required to post collateral for any of these agreements. If PECO, BGE, or DPL lost their investment
grade credit rating as of December 31, 2020, they could have been required to post incremental collateral to their counterparties of $34 million, $54 million,
and $9 million, respectively.

17. Debt and Credit Agreements (All Registrants)

Short-Term Borrowings

Exelon Corporate, ComEd, and BGE meet their short-term liquidity requirements primarily through the issuance of commercial paper. Generation and PECO
meet their short-term liquidity requirements primarily through the issuance of commercial paper and borrowings from the Exelon intercompany money pool.
Pepco, DPL, and ACE meet their short-term liquidity requirements primarily through the issuance of commercial paper and borrowings

Borrowings under Exelon’s, Generation’s, ComEd’s, PECO’s, BGE's, Pepco's, DPL's, and ACE's revolving credit agreements bear interest at a rate based
upon  either  the  prime  rate  or  a  LIBOR-based  rate,  plus  an  adder  based  upon  the  particular  Registrant’s  credit  rating.  The  adders  for  the  prime  based
borrowings and LIBOR-based borrowings are presented in the following table:

Includes interest rate adders at Exelon Corporate of 27.5 and 127.5 for prime and LIBOR-based borrowings, respectively.

If  any  registrant  loses  its  investment  grade  rating,  the  maximum  adders  for  prime  rate  borrowings  and  LIBOR-based  rate  borrowings  would  be  65  basis
points and 165 basis points, respectively. The credit agreements also require the borrower to pay a facility fee based upon the aggregate commitments. The
fee varies depending upon the respective credit ratings of the borrower.

Variable Rate Demand Bonds

DPL has outstanding obligations in respect of Variable Rate Demand Bonds (VRDB). VRDBs are subject to repayment on the demand of the holders and, for
this reason, are accounted for as short-term debt in accordance with GAAP. However, these bonds may be converted to a fixed-rate, fixed-term option to
establish a maturity which corresponds to the date of final maturity of the bonds. On this basis, PHI views VRDBs as a source of long-term financing. As of
both December 31, 2020 and December 31, 2019, $79 million in variable

Nonrecourse Debt 

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 17 — Debt and Credit Agreements

Exelon and Generation have issued nonrecourse debt financing, in which approximately $2.2 billion of generating assets have been pledged as collateral at
December 31, 2020. Borrowings under these agreements are secured by the assets and equity of each respective project. The lenders do not have recourse
against Exelon or Generation in the event of a default. If a specific project financing entity does not maintain compliance with its specific nonrecourse debt
financing covenants, there could be a requirement to accelerate repayment of the associated debt or other borrowings earlier than the stated maturity dates.
In these instances, if such repayment was not satisfied, the lenders or security holders would generally have rights to foreclose against the project-specific
assets  and  related  collateral.  The  potential  requirement  to  satisfy  its  associated  debt  or  other  borrowings  earlier  than  otherwise  anticipated  could  lead  to
impairments due to a higher likelihood of disposing of the respective project-specific assets significantly before the end of their useful lives.

Antelope Valley Solar Ranch One. In December 2011, the DOE Loan Programs Office issued a guarantee for up to $646 million for a nonrecourse loan
from the Federal Financing Bank to support the financing of the construction of the Antelope Valley facility. The project became fully operational in 2014. The
loan will mature on January 5, 2037. Interest rates on the loan were fixed upon each advance at a spread of 37.5 basis points above U.S. Treasuries of
comparable maturity. The advances were completed as of December 31, 2015 and the outstanding loan balance will bear interest at an average blended
interest rate of 2.82%. As of December 31, 2020 and December 31, 2019, approximately $460 million and $485 million were outstanding, respectively. In
addition,  Generation  has  issued  letters  of  credit  to  support  its  equity  investment  in  the  project.  As  of  December  31,  2020,  Generation  had  $37  million  in
letters  of  credit  outstanding  related  to  the  project.  In  December  2017,  Generation’s  interests  in  Antelope  Valley  were  contributed  to  and  are  pledged  as
collateral for the EGR IV financing structures referenced below.

Antelope  Valley  sells  all  of  its  output  to  PG&E  through  a  PPA.  On  January  29,  2019,  PG&E  filed  for  protection  under  Chapter  11  of  the  U.S.  Bankruptcy
Code, which created an event of default for Antelope Valley’s nonrecourse debt that provided the lender with a right to accelerate amounts outstanding under
the  loan  such  that  they  would  become  immediately  due  and  payable.  As  a  result  of  the  event  of  default  and  in  the  absence  of  a  waiver  from  the  lender
foregoing  their  acceleration  rights,  the  debt  was  reclassified  as  current  in  Exelon’s  and  Generation’s  Consolidated  Balance  Sheets  in  the  first  quarter  of
2019. Further, distributions from Antelope Valley to EGR IV were suspended.

The  United  States  Bankruptcy  Court  entered  an  order  on  June  20,  2020  confirming  PG&E’s  plan  of  reorganization.  On  July  1,  2020  the  plan  became
effective, and PG&E emerged from bankruptcy. On July 21, 2020, Antelope Valley received a waiver from the DOE for the event of default and, as such,
distributions  from  Antelope  Valley  to  EGR  IV  were  permitted  and  the  debt  was  classified  as  noncurrent  as  of  June  30,  2020.  The  debt  continues  to  be
presented as noncurrent as of December 31, 2020.

See Note 12 — Asset Impairments for additional information.

Continental Wind, LLC.  In September 2013, Continental Wind, an indirect subsidiary of Exelon and Generation, completed the issuance and sale of $613
million senior secured notes. Continental Wind owns and operates a portfolio of wind farms in Idaho, Kansas, Michigan, Oregon, New Mexico, and Texas
with a total net capacity of 667 MW. The net proceeds were distributed to Generation for its general business purposes. The notes are scheduled to mature
on February 28, 2033. The notes bear interest at a fixed rate of 6.00% with interest payable semi-annually. As of December 31, 2020 and December 31,
2019, approximately $415 million and $447 million were outstanding, respectively.

In addition, Continental Wind has a $122 million letter of credit facility and $4 million working capital revolver facility. Continental Wind has issued letters of
credit to satisfy certain of its credit support and security obligations. As of December 31, 2020, the Continental Wind letter of credit facility had $114 million in
letters of credit outstanding related to the project.

In  2017,  Generation’s  interests  in  Continental  Wind  were  contributed  to  EGRP.  Refer  to  Note  23  -  Variable  Interest  Entities  for  additional  information  on
EGRP.

Renewable Power Generation.    In March 2016, RPG, an indirect subsidiary of Exelon and Generation, issued $150 million aggregate principal amount of
a nonrecourse senior secured notes. The net proceeds were distributed to Generation for paydown of long term debt obligations at Sacramento PV Energy
and Constellation

Solar Horizons and for general business purposes. The loan is scheduled to mature on March 31, 2035. The term loan bears interest at a fixed rate of 4.11%
payable semi-annually. As of December 31, 2020 and December 31, 2019, approximately $95 million and $106 million were outstanding, respectively.

In 2017, Generation’s interests in RPG were contributed to EGRP. Refer to Note 23 - Variable Interest Entities for additional information on EGRP.

SolGen,  LLC.        In  September  2016,  SolGen,  an  indirect  subsidiary  of  Exelon  and  Generation,  issued  $150  million  aggregate  principal  amount  of  a
nonrecourse  senior  secured  notes. The  net  proceeds  were  distributed  to  Generation  for  general  business  purposes. The  loan  is  scheduled  to  mature  on
September  30,  2036.  The  term  loan  bears  interest  at  a  fixed  rate  of  3.93%  payable  semi-annually. As  of  December  31,  2020  and  December  31,  2019,
approximately $125 million and $131 million were outstanding, respectively. As a result of the sale agreement with an affiliate of Brookfield Renewable in the
fourth quarter of 2020, the outstanding balance was reclassified to Liabilities held for sale in Exelon's and Generation's Consolidated Balance Sheets as of
December  31,  2020.  In  2017,  Generation’s  interests  in  SolGen  were  contributed  to  and  were  pledged  as  collateral  for  the  EGR  IV  financing  structure.  In
December 2020, as part of the EGR IV financing, SolGen was removed from the collateral terms structured within the agreement. See EGR IV discussed
below for additional information and Note 2 — Mergers, Acquisitions, and Dispositions for additional information on the sale agreement.

ExGen Renewables IV.    In November 2017, EGR IV, an indirect subsidiary of Exelon and Generation, entered into an $850 million nonrecourse senior
secured term loan credit facility agreement with a maturity date of November 28, 2024. In addition to the financing, EGR IV entered into interest rate swaps
with an initial notional amount of $636 million at an interest rate of 2.32% to manage a portion of the interest rate exposure in connection with the financing.

In December 2020, EGR IV entered into a financing agreement for a $750 million nonrecourse senior secured term loan credit facility, scheduled to mature
on  December  15,  2027.  The  term  loan  bears  interest  at  a  variable  rate  equal  to  LIBOR  plus  2.75%,  subject  to  a  1%  LIBOR  floor  with  interest  payable
quarterly. In addition to the financing, EGR IV entered into interest rate swaps with an initial notional amount of $516 million at an interest rate of 1.05% to
manage a portion of the interest rate exposure in connection with the financing.

The  proceeds  were  used  to  repay  the  November  2017  nonrecourse  senior  secured  term  loan  credit  facility  of  $850  million,  of  which  $709  million  was
outstanding  as  of  the  retirement  date  in  December  of  2020,  and  to  settle  the  November  2017  interest  rate  swap.  Generation’s  interests  in  EGRP  and
Antelope Valley remained contributed to and are pledged as collateral for this financing. As of December 31, 2020, $750 million was outstanding. See Note
23 — Variable Interest Entities for additional information on EGRP and Note 16 — Derivative Financial Instruments for additional information on interest rate
swaps.

18. Fair Value of Financial Assets and Liabilities (All Registrants)

Exelon  measures  and  classifies  fair  value  measurements  in  accordance  with  the  hierarchy  as  defined  by  GAAP.  The  hierarchy  prioritizes  the  inputs  to
valuation techniques used to measure fair value into three levels as follows:

•

•

•

Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities that the Registrants have the ability to liquidate as of the
reporting date.

Level 2 — inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable
through corroboration with observable market data.

Level 3 — unobservable inputs, such as internally developed pricing models or third-party valuations for the asset or liability due to little or no
market activity for the asset or liability.

Note 18 — Fair Value of Financial Assets and Liabilities

Fair Value of Financial Liabilities Recorded at Amortized Cost

The following tables present the carrying amounts and fair values of the Registrants’ short-term liabilities, long-term debt, SNF obligation, and trust preferred
securities  (long-term  debt  to  financing  trusts  or  junior  subordinated  debentures)  as  of  December  31,  2020  and  2019.  The  Registrants  have  no  financial
liabilities classified as Level 1.

The carrying amounts of the Registrants’ short-term liabilities as presented on their Consolidated Balance Sheets are representative of their fair value (Level
2) because of the short-term nature of these instruments.

Long-Term Debt, including amounts due within one year

Taxable Debt Securities

Variable Rate Financing Debt

All

The fair value is determined by a valuation model that is based on a conventional discounted cash
flow methodology and utilizes assumptions of current market pricing curves. Exelon obtains credit
spreads based on trades of existing Exelon debt securities as well as other issuers in the utility
sector with similar credit ratings. The yields are then converted into discount rates of various
tenors that are used for discounting the respective cash flows of the same tenor for each bond or
note.

Exelon, Generation, DPL Debt rates are reset on a regular basis and the carrying value approximates fair value.

Exelon, Pepco, DPL, ACE

Exelon, Generation

Exelon, Generation, Pepco

Rates are obtained similar to the process for taxable debt securities. Due to low trading volume
and qualitative factors such as market conditions, low volume of investors, and investor demand,
these debt securities are Level 3.

The fair value is similar to the process for taxable debt securities. Due to the lack of market
trading data on similar debt, the discount rates are derived based on the original loan interest rate
spread to the applicable U.S. Treasury rate as well as a current market curve derived from
government-backed securities.

Fair value is based on market and quoted prices for its own and other nonrecourse debt with
similar risk profiles. Given the low trading volume in the nonrecourse debt market, the price
quotes used to determine fair value will reflect certain qualitative factors, such as market
conditions, investor demand, new developments that might significantly impact the project cash
flows or off-taker credit, and other circumstances related to the project.

Exelon, ComEd, PECO

Fair value is based on publicly traded securities issued by the financing trusts. Due to low trading
volume of these securities and qualitative factors, such as market conditions, investor demand,
and circumstances related to each issue, this debt is classified as Level 3.

SNF Obligation

2

Exelon, Generation

The carrying amount is derived from a contract with the DOE to provide for disposal of SNF from
Generation’s  nuclear  generating  stations.  When  determining  the  fair  value  of  the  obligation,  the
future carrying amount of the SNF obligation is calculated by compounding the current book value
of the SNF obligation at the 13-week U.S. Treasury rate. The compounded obligation amount is
discounted back to present value using Generation’s discount rate, which is calculated using the
same methodology as described above for the taxable debt securities, and an estimated maturity
date of 2035 and 2030 for the years ended December 31, 2020 and 2019, respectively.

Recurring Fair Value Measurements

The following tables present assets and liabilities measured and recorded at fair value in the Registrants' Consolidated Balance Sheets on a recurring basis
and their level within the fair value hierarchy as of December 31, 2020 and 2019:

the Consolidated Balance Sheets. Generation excludes cash of $171 million and $177 million at December 31, 2020 and 2019, respectively, and restricted cash of $20
million and $58 million at December 31, 2020 and 2019, respectively. 
Includes  $116  million  and  $90  million  of  cash  received  from  outstanding  repurchase  agreements  at  December  31,  2020  and  2019,  respectively,  and  is  offset  by  an
obligation to repay upon settlement of the agreement as discussed in (e) below.
Includes investments in equities sold short of $(62) million and $(48) million as of December 31, 2020 and 2019, respectively, held in an investment vehicle primarily to
hedge the equity option component of its convertible debt.
Includes derivative assets of $2 million and $2 million, which have total notional amounts of $1,043 million and $724 million at December 31, 2020 and 2019, respectively.
The notional principal amounts for these instruments provide one measure of the transaction volume outstanding as of the periods ended and do not represent the amount
of Exelon and Generation's exposure to credit or market loss.

(e) Excludes net liabilities of $181 million and $147 million at December 31, 2020 and 2019, respectively, which include certain derivative assets that have notional amounts of
$104 million and $99 million at December 31, 2020 and 2019, respectively. These items consist of receivables related to pending securities sales, interest and dividend
receivables, repurchase agreement obligations, and payables related to pending securities purchases. The repurchase agreements are generally short-term in nature with
durations generally of 30 days or less.

(f) Reflects equity investments held by Generation which were previously designated as equity investments without readily determinable fair values but are now publicly traded

and therefore have readily determinable fair values. Generation recorded the fair value of these investments in Other current assets on Exelon's and Generation's
Consolidated Balance Sheets based on the quoted market prices of the stocks at December 31, 2020, which resulted in an unrealized gain of $186 million within Other, net
in Exelon's and Generation's Consolidated Statement of Operations and Comprehensive Income for the year ended December 31, 2020.

(g) Collateral posted/(received) from counterparties, net of collateral paid to counterparties, totaled $(67) million, $321 million, and $162 million allocated to Level 1, Level 2,
and Level 3 mark-to-market derivatives, respectively, as of December 31, 2020. Collateral posted/(received) from counterparties, net of collateral paid to counterparties,
totaled $163 million, $551 million, and $214 million allocated to Level 1, Level 2, and Level 3 mark-to-market derivatives, respectively, as of December 31, 2019.
(h) Of the collateral posted/(received), $209 million and $511 million represents variation margin on the exchanges as of December 31, 2020 and 2019, respectively.

As of December 31, 2020, Exelon and Generation have outstanding commitments to invest in private credit, private equity, and real estate investments of
approximately $195 million, $254 million, and $369 million, respectively. These commitments will be funded by Generation’s existing NDT funds.

Exelon and Generation held investments without readily determinable fair values with carrying amounts of $73 million and $55 million as of December 31,
2020, respectively. Exelon and Generation held investments without readily determinable fair values with carrying amounts of $69 million as of December 31,
2019. Changes in fair value, cumulative adjustments, and impairments were not material for the years ended December 31, 2020 and December 31, 2019.

Valuation Techniques Used to Determine Fair Value

Cash  Equivalents  (All  Registrants). Investments  with  original  maturities  of  three  months  or  less  when  purchased,  including  mutual  and  money  market
funds,  are  considered  cash  equivalents.  The  fair  values  are  based  on  observable  market  prices  and,  therefore,  are  included  in  the  recurring  fair  value
measurements hierarchy as Level 1.

NDT  Fund  Investments  (Exelon  and  Generation).  The  trust  fund  investments  have  been  established  to  satisfy  Generation’s  and  CENG's  nuclear
decommissioning obligations as required by the NRC. The NDT funds hold debt and equity securities directly and indirectly through commingled funds and
mutual funds, which are included in equities and fixed income. Generation’s and CENG's NDT fund investments policies outline investment guidelines for the
trusts and limit the trust funds’ exposures to investments in highly illiquid markets and other alternative investments, including private credit, private equity,
and  real  estate.  Investments  with  maturities  of  three  months  or  less  when  purchased,  including  certain  short-term  fixed  income  securities  are  considered
cash equivalents and included in the recurring fair value measurements hierarchy as Level 1 or Level 2.

Equities. These investments consist of individually held equity securities, equity mutual funds, and equity commingled funds in domestic and foreign markets.
With respect to individually held equity securities, the trustees obtain prices from pricing services, whose prices are generally obtained from direct feeds from
market exchanges, which Exelon and Generation are able to independently corroborate. Equity securities held individually, including real estate investment
trusts, rights, and warrants, are primarily traded on exchanges that contain only actively traded securities due to the volume trading requirements imposed by
these exchanges. The equity securities that are held directly by the trust funds are valued based on quoted prices in active markets and categorized as Level
1. Certain equity securities have been categorized as Level 2 because they are based on evaluated prices that reflect observable market information, such
as actual trade information or similar securities. Certain private placement equity securities are categorized as Level 3 because they are not publicly traded
and are priced using significant unobservable inputs.

Equity commingled funds and mutual funds are maintained by investment companies, and fund investments are held in accordance with a stated set of fund
objectives. The values of some of these funds are publicly quoted. For mutual funds which are publicly quoted, the funds are valued based on quoted prices
in  active  markets  and  have  been  categorized  as  Level  1.  For  equity  commingled  funds  and  mutual  funds  which  are  not  publicly  quoted,  the  fund
administrators  value  the  funds  using  the  NAV  per  fund  share,  derived  from  the  quoted  prices  in  active  markets  of  the  underlying  securities  and  are  not
classified within the fair value hierarchy. These investments typically can be redeemed monthly or more frequently, with 30 or less days of notice and without
further restrictions.

Fixed income. For fixed income securities, which consist primarily of corporate debt securities, U.S. government securities, foreign government securities,
municipal  bonds,  asset  and  mortgage-backed  securities,  commingled  funds,  mutual  funds,  and  derivative  instruments,  the  trustees  obtain  multiple  prices
from pricing vendors whenever possible, which enables cross-provider validations in addition to checks for unusual daily movements. A primary price source
is  identified  based  on  asset  type,  class,  or  issue  for  each  security.  With  respect  to  individually  held  fixed  income  securities,  the  trustees  monitor  prices
supplied  by  pricing  services  and  may  use  a  supplemental  price  source  or  change  the  primary  price  source  of  a  given  security  if  the  portfolio  managers
challenge an assigned price and the trustees determine that another price source is considered to be preferable. Exelon and Generation have obtained an
understanding  of  how  these  prices  are  derived,  including  the  nature  and  observability  of  the  inputs  used  in  deriving  such  prices.  Additionally,  Exelon  and
Generation selectively

corroborate the fair values of securities by comparison to other market-based price sources. Investments in U.S. Treasury securities have been categorized
as Level 1 because they trade in highly-liquid and transparent markets. Certain private placement fixed income securities have been categorized as Level 3
because they are priced using certain significant unobservable inputs and are typically illiquid. The remaining fixed income securities, including certain other
fixed income investments, are based on evaluated prices that reflect observable market information, such as actual trade information of similar securities,
adjusted for observable differences and are categorized as Level 2.

Other fixed income investments primarily consist of fixed income commingled funds and mutual funds, which are maintained by investment companies and
hold fund investments in accordance with a stated set of fund objectives. The values of some of these funds are publicly quoted. For mutual funds which are
publicly quoted, the funds are valued based on quoted prices in active markets and have been categorized as Level 1. For fixed income commingled funds
and mutual funds which are not publicly quoted, the fund administrators value the funds using the NAV per fund share, derived from the quoted prices in
active markets of the underlying securities and are not classified within the fair value hierarchy. These investments typically can be redeemed monthly or
more frequently, with 30 or less days of notice and without further restrictions.

Derivative instruments. These instruments, consisting primarily of futures and swaps to manage risk, are recorded at fair value. Over-the-counter derivatives
are valued daily, based on quoted prices in active markets and trade in open markets, and have been categorized as Level 1. Derivative instruments other
than over-the-counter derivatives are valued based on external price data of comparable securities and have been categorized as Level 2.

Private credit. Private credit investments primarily consist of investments in private debt strategies. These investments are generally less liquid assets with
an  underlying  term  of  3  to  5  years  and  are  intended  to  be  held  to  maturity.  The  fair  value  of  these  investments  is  determined  by  the  fund  manager  or
administrator using a combination of valuation models including cost models, market models, and income models and typically cannot be redeemed until
maturity of the term loan. Private credit investments held directly by Exelon and Generation are categorized as Level 3 because they are based largely on
inputs that are unobservable and utilize complex valuation models. For managed private credit funds, the fair value is determined using a combination of
valuation  models  including  cost  models,  market  models,  and  income  models  and  typically  cannot  be  redeemed  until  maturity  of  the  term  loan.  Managed
private  credit  fund  investments  are  not  classified  within  the  fair  value  hierarchy  because  their  fair  value  is  determined  using  NAV  or  its  equivalent  as  a
practical expedient.

Private equity. These investments include those in limited partnerships that invest in operating companies that are not publicly traded on a stock exchange
such  as  leveraged  buyouts,  growth  capital,  venture  capital,  distressed  investments,  and  investments  in  natural  resources.  These  investments  typically
cannot be redeemed and are generally liquidated over a period of 8 to 10 years from the initial investment date, which is based on Exelon's understanding of
the  investment  funds.  Private  equity  valuations  are  reported  by  the  fund  manager  and  are  based  on  the  valuation  of  the  underlying  investments,  which
include unobservable inputs such as cost, operating results, discounted future cash flows, and market based comparable data. These valuation inputs are
unobservable.  The  fair  value  of  private  equity  investments  is  determined  using  NAV  or  its  equivalent  as  a  practical  expedient,  and  therefore,  these
investments are not classified within the fair value hierarchy.

Real estate. These investments are funds with a direct investment in pools of real estate properties. These funds are reported by the fund manager and are
generally  based  on  independent  appraisals  from  sources  with  professional  qualifications,  typically  using  a  combination  of  market  comparables  and
discounted cash flows. These valuation inputs are unobservable. The fair value of real estate investments is determined using NAV or its equivalent as a
practical expedient, and therefore, these investments are not classified within the fair value hierarchy.

Generation evaluated its NDT portfolios for the existence of significant concentrations of credit risk as of December 31, 2020. Types of concentrations that
were  evaluated  include,  but  are  not  limited  to,  investment  concentrations  in  a  single  entity,  type  of  industry,  foreign  country,  and  individual  fund.  As  of
December 31, 2020, there were no significant concentrations (generally defined as greater than 10 percent) of risk in Generation's NDT assets.

See Note 10 — Asset Retirement Obligations for additional information on the NDT fund investments. See Note 15 — Retirement Benefits for the valuation
techniques used for hedge fund investments.

Note 18 — Fair Value of Financial Assets and Liabilities

Rabbi Trust Investments (Exelon, Generation, PECO, BGE, PHI, Pepco, DPL, and ACE). The Rabbi trusts were established to hold assets related to
deferred compensation plans existing for certain active and retired members of Exelon’s executive management and directors. The Rabbi trusts' assets are
included in investments in the Registrants’ Consolidated Balance Sheets and consist primarily of money market funds, mutual funds, fixed income securities,
and life insurance policies. Money market funds and mutual funds are publicly quoted and have been categorized as Level 1 given the clear observability of
the  prices.  The  fair  values  of  fixed  income  securities  are  based  on  evaluated  prices  that  reflect  observable  market  information,  such  as  actual  trade
information or similar securities, adjusted for observable differences and are categorized in Level 2. The life insurance policies are valued using the cash
surrender value of the policies, net of loans against those policies, which is provided by a third-party. Certain life insurance policies, which consist primarily of
mutual funds that are priced based on observable market data, have been categorized as Level 2 because the life insurance policies can be liquidated at the
reporting date for the value of the underlying assets. Life insurance policies that are valued using unobservable inputs have been categorized as Level 3,
where the fair value is determined based on the cash surrender value of the policy, which contains unobservable inputs and assumptions. Because Exelon
relies  on  its  third-party  insurance  provider  to  develop  the  inputs  without  adjustment  for  the  valuations  of  its  Level  3  investments,  quantitative  information
about  significant  unobservable  inputs  used  in  valuing  these  investments  is  not  reasonably  available  to  Exelon.  Therefore,  Exelon  has  not  disclosed  such
inputs.

Deferred  Compensation  Obligations  (All  Registrants).    The  Registrants’  deferred  compensation  plans  allow  participants  to  defer  certain  cash
compensation into a notional investment account. The Registrants include such plans in other current and noncurrent liabilities in their Consolidated Balance
Sheets. The value of the Registrants’ deferred compensation obligations is based on the market value of the participants’ notional investment accounts. The
underlying  notional  investments  are  comprised  primarily  of  equities,  mutual  funds,  commingled  funds,  and  fixed  income  securities  which  are  based  on
directly and indirectly observable market prices. Since the deferred compensation obligations themselves are not exchanged in an active market, they are
categorized as Level 2 in the fair value hierarchy.

The value of certain employment agreement obligations (which are included with the Deferred Compensation Obligation in the tables above) are based on a
known and certain stream of payments to be made over time and are categorized as Level 2 within the fair value hierarchy.

Investments  in  Equities  (Exelon  and  Generation). Exelon  and  Generation  hold  certain  investments  in  equity  securities  with  readily  determinable  fair
values in addition to those held within the NDT funds. These equity securities are valued based on quoted prices in active markets and are categorized as
Level 1.

Deferred Purchase Price Consideration (Exelon and Generation).  Exelon and Generation have DPP consideration for the sale of certain receivables of
retail electricity at Generation. This amount is valued based on the sales price of the receivables net of allowance for credit losses based on accounts
receivable aging historical experience coupled with specific identification through a credit monitoring process, which considers current conditions and
forward-looking information such as industry trends, macroeconomic factors, changes in the regulatory environment, external credit ratings, publicly available
news, payment status, payment history, and the exercise of collateral calls. Since the DPP consideration is based on the sales price of the receivables, it is
categorized as Level 2 in the fair value hierarchy. See Note 6 — Accounts Receivable for additional information on the sale of certain receivables.

Mark-to-Market  Derivatives  (Exelon,  Generation,  and  ComEd).  Derivative  contracts  are  traded  in  both  exchange-based  and  non-exchange-based
markets. Exchange-based derivatives that are valued using unadjusted quoted prices in active markets are categorized in Level 1 in the fair value hierarchy.
Certain derivatives’ pricing is verified using indicative price quotations available through brokers or over-the-counter, on-line exchanges and are categorized
in Level 2. These price quotations reflect the average of the bid-ask, mid-point prices and are obtained from sources that the Registrants believe provide the
most  liquid  market  for  the  commodity.  The  price  quotations  are  reviewed  and  corroborated  to  ensure  the  prices  are  observable  and  representative  of  an
orderly  transaction  between  market  participants.  This  includes  consideration  of  actual  transaction  volumes,  market  delivery  points,  bid-ask  spreads,  and
contract duration. The remainder of derivative contracts are valued using the Black model, an industry standard option valuation model. The Black model
takes into account inputs such as contract terms, including maturity, and market parameters, including assumptions of the future prices of energy, interest
rates, volatility, credit worthiness, and credit spread. For derivatives that trade in liquid markets, such as generic forwards, swaps, and options, model inputs
are generally observable. Such instruments are categorized in Level 2. The Registrants’ derivatives are predominantly at liquid trading points.

335

(Dollars in millions, except per share data unless otherwise noted)

Note 18 — Fair Value of Financial Assets and Liabilities

For  derivatives  that  trade  in  less  liquid  markets  with  limited  pricing  information,  model  inputs  generally  would  include  both  observable  and  unobservable
inputs. These valuations may include an estimated basis adjustment from an illiquid trading point to a liquid trading point for which active price quotations are
available. Such instruments are categorized in Level 3.

For valuations that include both observable and unobservable inputs, if the unobservable input is determined to be significant to the overall inputs, the entire
valuation  is  categorized  in  Level  3.  This  includes  derivatives  valued  using  indicative  price  quotations  whose  contract  tenure  extends  into  unobservable
periods. In instances where observable data is unavailable, consideration is given to the assumptions that market participants would use in valuing the asset
or liability. This includes assumptions about market risks such as liquidity, volatility, and contract duration. Such instruments are categorized in Level 3 as the
model inputs generally are not observable. Forward price curves for the power market utilized by the front office to manage the portfolio, are reviewed and
verified by the middle office, and used for financial reporting by the back office. The Registrants consider credit and nonperformance risk in the valuation of
derivative contracts categorized in Level 2 and 3, including both historical and current market data, in their assessment of credit and nonperformance risk by
counterparty. Due to master netting agreements and collateral posting requirements, the impacts of credit and nonperformance risk were not material to the
financial statements.

Disclosed below is detail surrounding the Registrants’ significant Level 3 valuations. The calculated fair value includes marketability discounts for margining
provisions  and  other  attributes.  Generation’s  Level  3  balance  generally  consists  of  forward  sales  and  purchases  of  power  and  natural  gas  and  certain
transmission congestion contracts. Generation utilizes various inputs and factors including market data and assumptions that market participants would use
in pricing assets or liabilities as well as assumptions about the risks inherent in the inputs to the valuation technique. The inputs and factors include forward
commodity prices, commodity price volatility, contractual volumes, delivery location, interest rates, credit quality of counterparties, and credit enhancements.

For commodity derivatives, the primary input to the valuation models is the forward commodity price curve for each instrument. Forward commodity price
curves are derived by risk management for liquid locations and by the traders and portfolio managers for illiquid locations. All locations are reviewed and
verified  by  risk  management  considering  published  exchange  transaction  prices,  executed  bilateral  transactions,  broker  quotes,  and  other  observable  or
public data sources. The relevant forward commodity curve used to value each of the derivatives depends on a number of factors, including commodity type,
delivery location, and delivery period. Price volatility varies by commodity and location. When appropriate, Generation discounts future cash flows using risk
free interest rates with adjustments to reflect the credit quality of each counterparty for assets and Generation’s own credit quality for liabilities. The level of
observability of a forward commodity price varies generally due to the delivery location and delivery period. Certain delivery locations including PJM West
Hub (for power) and Henry Hub (for natural gas) are more liquid and prices are observable for up to three years in the future. The observability period of
volatility is generally shorter than the underlying power curve used in option valuations. The forward curve for a less liquid location is estimated by using the
forward curve from the liquid location and applying a spread to represent the cost to transport the commodity to the delivery location. This spread does not
typically  represent  a  majority  of  the  instrument’s  market  price.  As  a  result,  the  change  in  fair  value  is  closely  tied  to  liquid  market  movements  and  not  a
change in the applied spread. The change in fair value associated with a change in the spread is generally immaterial. An average spread calculated across
all Level 3 power and gas delivery locations is approximately $2.49 and $0.38 for power and natural gas, respectively. Many of the commodity derivatives
are short term in nature and thus a majority of the fair value may be based on observable inputs even though the contract as a whole must be classified as
Level 3.

On December 17, 2010, ComEd entered into several 20-year floating to fixed energy swap contracts with unaffiliated suppliers for the procurement of long-
term renewable energy and associated RECs. See Note 16 — Derivative Financial Instruments for additional information. The fair value of these swaps has
been designated as a Level 3 valuation due to the long tenure of the positions and internal modeling assumptions. The modeling assumptions include using
natural  gas  heat  rates  to  project  long  term  forward  power  curves  adjusted  by  a  renewable  factor  that  incorporates  time  of  day  and  seasonality  factors  to
reflect accurate renewable energy pricing. In addition, marketability reserves are applied to the positions based on the tenor and supplier risk.

(a) The valuation techniques, unobservable inputs, ranges, and arithmetic averages are the same for the asset and liability positions.
(b) The  fair  values  do  not  include  cash  collateral  posted  on  level  three  positions  of  $162  million  and  $214  million  as  of  December  31,  2020  and  December  31,  2019,

respectively.

(c) Quoted forward natural gas rates are utilized to project the forward power curve for the delivery of energy at specified future dates. The natural gas curve is extrapolated

beyond its observable period to the end of the contract’s delivery.

The inputs listed above, which are as of the balance sheet date, would have a direct impact on the fair values of the above instruments if they were adjusted.
The significant unobservable inputs used in the fair value measurement of Generation’s commodity derivatives are forward commodity prices and for options
is price volatility. Increases (decreases) in the forward commodity price in isolation would result in significantly higher (lower) fair values for long positions
(contracts that give Generation the obligation or option to purchase a commodity), with offsetting impacts to short positions (contracts that give Generation
the obligation or right to sell a commodity). Increases (decreases) in volatility would increase (decrease) the value for the holder of the option (writer of the
option). Generally, a change in the estimate of forward commodity prices is unrelated to a change in the estimate of volatility of prices. An increase to the
reserves  listed  above  would  decrease  the  fair  value  of  the  positions.  An  increase  to  the  heat  rate  or  renewable  factors  would  increase  the  fair  value
accordingly. Generally, interrelationships exist between market prices of natural gas and power. As such, an increase in natural gas pricing would potentially
have a similar impact on forward power markets.

(a) Remaining commitments extend through 2026 and include rate credits, energy efficiency programs, and delivery system modernization.

In  addition,  Exelon  is  committed  to  develop  or  to  assist  in  the  commercial  development  of  approximately  37  MWs  of  new  solar  generation  in  Maryland,
District  of  Columbia,  and  Delaware  at  an  estimated  cost  of  approximately  $135  million,  which  will  generate  future  earnings  at  Exelon  and  Generation.
Investment  costs,  which  are  expected  to  be  primarily  capital  in  nature,  are  recognized  as  incurred  and  recorded  in  Exelon's  and  Generation's  financial
statements. As of December 31, 2020, 27 MWs of new generation were developed and Exelon and Generation have incurred costs of $119 million. Exelon
has also committed to purchase 100 MWs of wind energy in PJM. DPL has committed to conducting three RFPs to procure up to a total of 120 MWs of wind
RECs for the purpose of meeting Delaware's renewable portfolio standards. DPL has conducted two of the three wind REC RFPs. The first 40 MW wind
REC  tranche  was  conducted  in  2017  and  did  not  result  in  a  purchase  agreement.  The  second  40  MW  wind  REC  tranche  was  conducted  in  2018  and
resulted  in  a  proposed  REC  purchase  agreement  that  was  approved  by  the  DPSC  in  March  2019.  The  third  and  final  40  MW  wind  REC  tranche  will  be
conducted in 2022.

(b) Represents the maximum potential obligation in the event that the fair value of certain leased equipment and fleet vehicles is zero at the end of the maximum lease term.
The  lease  term  associated  with  these  assets  ranges  from  1  to  8  years.  The  maximum  potential  obligation  at  the  end  of  the  minimum  lease  term  would  be  $71  million
guaranteed by Exelon and PHI, of which $24 million, $30 million, and $17 million is guaranteed by Pepco, DPL, and ACE, respectively. Historically, payments under the
guarantees have not been made and PHI believes the likelihood of payments being required under the guarantees is remote.

Nuclear Insurance (Exelon and Generation)

Generation is subject to liability, property damage, and other risks associated with major incidents at any of its nuclear stations. Generation has mitigated its
financial exposure to these risks through insurance and other industry risk-sharing provisions.

The Price-Anderson Act was enacted to ensure the availability of funds for public liability claims arising from an incident at any of the U.S. licensed nuclear
facilities and to limit the liability of nuclear reactor owners for such claims from any single incident. As of December 31, 2020, the current liability limit per
incident is $13.8 billion and is subject to change to account for the effects of inflation and changes in the number of licensed reactors at least once every five
years with the last adjustment effective November 1, 2018. In accordance with the Price-Anderson Act, Generation maintains financial protection at levels
equal to the amount of liability insurance available from private sources through the purchase of private nuclear energy liability insurance for public liability
claims that could arise in the event of an incident. Effective January 1, 2017, the required amount of nuclear energy liability insurance purchased is $450
million for each operating site. Claims exceeding that amount are covered through mandatory participation in a financial protection pool, as required by the
Price  Anderson-Act,  which  provides  the  additional  $13.3  billion  per  incident  in  funds  available  for  public  liability  claims.  Participation  in  this  secondary
financial protection pool requires the operator of each reactor to fund its proportionate share of costs for any single incident that exceeds the primary layer of
financial  protection.  Generation’s  share  of  this  secondary  layer  would  be  approximately  $2.9 billion,  however  any  amounts  payable  under  this  secondary
layer would be capped at $434 million per year.

In addition, the U.S. Congress could impose revenue-raising measures on the nuclear industry to pay public liability claims exceeding the $13.8 billion limit
for a single incident.

As part of the execution of the NOSA on April 1, 2014, Generation executed an Indemnity Agreement pursuant to which Generation agreed to indemnify
EDF and its affiliates against third-party claims that may arise from any future nuclear incident (as defined in the Price-Anderson Act) in connection with the
CENG  nuclear  plants  or  their  operations.  Exelon  guarantees  Generation’s  obligations  under  this  indemnity.  See  Note  23  —  Variable  Interest  Entities  for
additional information on Generation’s operations relating to CENG.

Generation  is  required  each  year  to  report  to  the  NRC  the  current  levels  and  sources  of  property  insurance  that  demonstrates  Generation  possesses
sufficient financial resources to stabilize and decontaminate a reactor and reactor station site in the event of an accident. The property insurance maintained
for  each  facility  is  currently  provided  through  insurance  policies  purchased  from  NEIL,  an  industry  mutual  insurance  company  of  which  Generation  is  a
member.

NEIL may declare distributions to its members as a result of favorable operating experience. In recent years, NEIL has made distributions to its members,
but Generation cannot predict the level of future distributions or if they will continue at all. Generation's portion of the annual distribution declared by NEIL is
estimated to be $75 million for  2020,  and was $136 million and $58 million  for  2019  and  2018,  respectively.  In  addition,  in  March  2018,  NEIL  declared  a
supplemental  distribution.  Generation's  portion  of  the  supplemental  distribution  declared  by  NEIL  was  $31 million.  The  distributions  were  recorded  as  a
reduction to Operating and maintenance expense within Exelon and Generation’s Consolidated Statements of Operations and Comprehensive Income.

Premiums  paid  to  NEIL  by  its  members  are  also  subject  to  a  potential  assessment  for  adverse  loss  experience  in  the  form  of  a  retrospective  premium
obligation. NEIL has never assessed this retrospective premium since its formation in 1973, and Generation cannot predict the level of future assessments, if
any. The current maximum aggregate annual retrospective premium obligation for Generation is approximately $252 million. NEIL requires its members to
maintain an investment grade credit rating or to ensure collectability of their annual retrospective premium obligation by providing a financial guarantee, letter
of credit, deposit premium, or some other means of assurance.

Note 19 — Commitments and Contingencies

NEIL provides “all risk” property damage, decontamination, and premature decommissioning insurance for each station for losses resulting from damage to
its nuclear plants, either due to accidents or acts of terrorism. If the decision is made to decommission the facility, a portion of the insurance proceeds will be
allocated  to  a  fund,  which  Generation  is  required  by  the  NRC  to  maintain,  to  provide  for  decommissioning  the  facility.  In  the  event  of  an  insured  loss,
Generation is unable to predict the timing of the availability of insurance proceeds to Generation and the amount of such proceeds that would be available. In
the event that one or more acts of terrorism cause accidental property damage within a twelve-month period from the first accidental property damage under
one or more policies for all insured plants, the maximum recovery by Generation will be an aggregate of $3.2 billion plus such additional amounts as the
insurer may recover for all such losses from reinsurance, indemnity, and any other source, applicable to such losses.

For its insured losses, Generation is self-insured to the extent that losses are within the policy deductible or exceed the amount of insurance maintained.
Uninsured  losses  and  other  expenses,  to  the  extent  not  recoverable  from  insurers  or  the  nuclear  industry,  could  also  be  borne  by  Generation.  Any  such
losses could have a material adverse effect on Exelon’s and Generation’s financial statements.

Spent Nuclear Fuel Obligation (Exelon and Generation)

Under  the  NWPA,  the  DOE  is  responsible  for  the  development  of  a  geologic  repository  for  and  the  disposal  of  SNF  and  high-level  radioactive  waste.  As
required  by  the  NWPA,  Generation  is  a  party  to  contracts  with  the  DOE  (Standard  Contracts)  to  provide  for  disposal  of  SNF  from  Generation’s  nuclear
generating stations. In accordance with the NWPA and the Standard Contracts, Generation historically had paid the DOE one mill ($0.001) per kWh of net
nuclear generation for the cost of SNF disposal. Due to the lack of a viable disposal program, the DOE reduced the SNF disposal fee to zero in May 2014.
Until  a  new  fee  structure  is  in  effect,  Exelon  and  Generation  will  not  accrue  any  further  costs  related  to  SNF  disposal  fees.  This  fee  may  be  adjusted
prospectively to ensure full cost recovery.

Generation currently assumes the DOE will begin accepting SNF in 2035 and uses that date for purposes of estimating the nuclear decommissioning asset
retirement obligations. The SNF acceptance date assumption is based on management’s estimates of the amount of time required for DOE to select a site
location and develop the necessary infrastructure for long-term SNF storage.

The NWPA and the Standard Contracts required the DOE to begin taking possession of SNF generated by nuclear generating units by no later than January
31, 1998. The DOE, however, failed to meet that deadline and its performance is expected to be delayed significantly. In August 2004, Generation and the
DOJ,  in  close  consultation  with  the  DOE,  reached  a  settlement  under  which  the  government  agreed  to  reimburse  Generation,  subject  to  certain  damage
limitations based on the extent of the government’s breach, for costs associated with storage of SNF at Generation’s  nuclear stations pending the DOE’s
fulfillment of its obligations. Generation’s settlement agreement does not include FitzPatrick and FitzPatrick does not currently have a settlement agreement
in place. Calvert Cliffs, Ginna, and Nine Mile Point each have separate settlement agreements in place with the DOE which were extended during 2020 to
provide for the reimbursement of SNF storage costs through December 31, 2022. Generation submits annual reimbursement requests to the DOE for costs
associated  with  the  storage  of  SNF.  In  all  cases,  reimbursement  requests  are  made  only  after  costs  are  incurred  and  only  for  costs  resulting  from  DOE
delays in accepting the SNF.

Under  the  settlement  agreements,  Generation  received  total  cumulative  cash  reimbursements  of  $1,455  million  through  December  31,  2020  for  costs
incurred.  After  considering  the  amounts  due  to  co-owners  of  certain  nuclear  stations  and  to  the  former  owner  of  Oyster  Creek,  Generation  received  net
cumulative  cash reimbursements of $1,266 million. As  of  December  31,  2020  and  2019,  the  amount  of  SNF  storage  costs  for  which  reimbursement  has
been or will be requested from the DOE under the DOE settlement agreements is as follows:

(a) ComEd previously elected to defer payment of the one-time fee of $277 million for its units (which are now part of Generation), with interest to the date of payment, until
just  prior  to  the  first  delivery  of  SNF  to  the  DOE.  The  unfunded  liabilities  for  SNF  disposal  costs,  including  the  one-time  fee,  were  transferred  to  Generation  as  part  of
Exelon’s 2001 corporate restructuring.

(b) A  prior  owner  of  FitzPatrick  elected  to  defer  payment  of  the  one-time  fee  of  $34  million,  with  interest  to  the  date  of  payment,  for  the  FitzPatrick  unit.  As  part  of  the
FitzPatrick  acquisition  on  March  31,  2017,  Generation  assumed  a  SNF  liability  for  the  DOE  one-time  fee  obligation  with  interest  related  to  FitzPatrick  along  with  an
offsetting asset, included in Other deferred debits and other assets, for the contractual right to reimbursement from NYPA, a prior owner of FitzPatrick, for amounts paid for
the FitzPatrick DOE one-time fee obligation.

Interest  for  Exelon's  and  Generation's  SNF  liabilities  accrues  at  the  13-week  Treasury  Rate.  The  13-week  Treasury  Rate  in  effect  for  calculation  of  the
interest accrual at December 31, 2020 was 0.096% for the deferred amount transferred from ComEd and 0.101% for the deferred FitzPatrick amount.

Environmental Remediation Matters

General  (All  Registrants).  The  Registrants’  operations  have  in  the  past,  and  may  in  the  future,  require  substantial  expenditures  to  comply  with
environmental laws. Additionally, under Federal and state environmental laws, the Registrants are generally liable for the costs of remediating environmental
contamination of property now or formerly owned by them and of property contaminated by hazardous substances generated by them. The Registrants own
or  lease  a  number  of  real  estate  parcels,  including  parcels  on  which  their  operations  or  the  operations  of  others  may  have  resulted  in  contamination  by
substances that are considered hazardous under environmental laws. In addition, the Registrants are currently involved in a number of proceedings relating
to  sites  where  hazardous  substances  have  been  deposited  and  may  be  subject  to  additional  proceedings  in  the  future.  Unless  otherwise  disclosed,  the
Registrants cannot reasonably estimate whether they will incur significant liabilities for additional investigation and remediation costs at these or additional
sites  identified  by  the  Registrants,  environmental  agencies,  or  others,  or  whether  such  costs  will  be  recoverable  from  third  parties,  including  customers.
Additional costs could have a material, unfavorable impact on the Registrants' financial statements.

MGP Sites (Exelon and the Utility Registrants). ComEd, PECO, BGE, and DPL have identified sites where former MGP or gas purification activities have
or  may  have  resulted  in  actual  site  contamination.  For  almost  all  of  these  sites,  there  are  additional  PRPs  that  may  share  responsibility  for  the  ultimate
remediation of each location.

•

•

•

•

ComEd has 21 sites that are currently under some degree of active study and/or remediation. ComEd expects the majority of the remediation at
these sites to continue through at least 2026.

PECO has 8 sites that are currently under some degree of active study and/or remediation. PECO expects the majority of the remediation at these
sites to continue through at least 2023.

BGE has 4 sites that currently require some level of remediation and/or ongoing activity. BGE expects the majority of the remediation at these sites
to continue through at least 2023.

DPL has 1 site that is currently under study and the required cost at the site is not expected to be material.

The  historical  nature  of  the  MGP  and  gas  purification  sites  and  the  fact  that  many  of  the  sites  have  been  buried  and  built  over,  impacts  the  ability  to
determine  a  precise  estimate  of  the  ultimate  costs  prior  to  initial  sampling  and  determination  of  the  exact  scope  and  method  of  remedial  activity.
Management  determines  its  best  estimate  of  remediation  costs  using  all  available  information  at  the  time  of  each  study,  including  probabilistic  and
deterministic  modeling  for  ComEd  and  PECO,  and  the  remediation  standards  currently  required  by  the  applicable  state  environmental  agency.  Prior  to
completion of any significant clean up, each site remediation plan is approved by the appropriate state environmental agency.

ComEd,  pursuant  to  an  ICC  order,  and  PECO,  pursuant  to  settlements  of  natural  gas  distribution  rate  cases  with  the  PAPUC,  are  currently  recovering
environmental remediation costs of former MGP facility sites through customer rates. While BGE and DPL do not have riders for MGP clean-up costs, they
have historically received recovery of actual clean-up costs in distribution rates.

As of December 31, 2020 and 2019, the Registrants had accrued the following undiscounted amounts for environmental liabilities in Other current liabilities
and Other deferred credits and other liabilities within their respective Consolidated Balance Sheets:

Cotter Corporation (Exelon and Generation). The EPA has advised Cotter Corporation (Cotter), a former ComEd subsidiary, that it is potentially liable in
connection with radiological contamination at a site known as the West Lake Landfill in Missouri. In 2000, ComEd sold Cotter to an unaffiliated third-party. As
part  of  the  sale,  ComEd  agreed  to  indemnify  Cotter  for  any  liability  arising  in  connection  with  the  West  Lake  Landfill.  In  connection  with  Exelon’s  2001
corporate restructuring, this responsibility to indemnify Cotter was transferred to Generation. Including Cotter, there are three PRPs participating in the West
Lake Landfill remediation proceeding. Investigation by Generation has identified a number of other parties who also may be PRPs and could be liable to
contribute to the final remedy. Further investigation is ongoing.

In  September  2018,  the  EPA  issued  its  Record  of  Decision  (ROD)  Amendment  for  the  selection  of  a  final  remedy.  The  ROD  Amendment  modified  the
remedy previously selected by EPA in its 2008 ROD. While the 2008 ROD

343

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 19 — Commitments and Contingencies

required only that the radiological materials and other wastes at the site be capped, the 2018 ROD Amendment requires partial excavation of the radiological
materials  in  addition  to  the  previously  selected  capping  remedy.  The  ROD  Amendment  also  allows  for  variation  in  depths  of  excavation  depending  on
radiological  concentrations.  The  EPA  and  the  PRPs  have  entered  into  a  Consent  Agreement  to  perform  the  Remedial  Design,  which  is  expected  to  be
completed by early 2022. In March 2019 the PRPs received Special Notice Letters from the EPA to perform the Remedial Action work. On October 8, 2019,
Cotter (Generation’s indemnitee) provided a non-binding good faith offer to conduct, or finance, a portion of the remedy, subject to certain conditions. The
total estimated cost of the remedy, taking into account the current EPA technical requirements and the total costs expected to be incurred collectively by the
PRPs in fully executing the remedy, is approximately $280 million, including cost escalation on an undiscounted basis, which would be allocated among the
final group of PRPs. Generation has determined that a loss associated with the EPA’s partial excavation and enhanced landfill cover remedy is probable and
has recorded a liability, included in the table above, that reflects management’s best estimate of Cotter’s allocable share of the ultimate cost. Given the joint
and several nature of this liability, the magnitude of Generation’s ultimate liability will depend on the actual costs incurred to implement the required remedy
as well as on the nature and terms of any cost-sharing arrangements with the final group of PRPs. Therefore, it is reasonably possible that the ultimate cost
and Cotter's associated allocable share could differ significantly once these uncertainties are resolved, which could have a material impact on Exelon's and
Generation's future financial statements.

One of the other PRPs has indicated it will be making a contribution claim against Cotter for costs that it has incurred to prevent the subsurface fire from
spreading to those areas of the West Lake Landfill where radiological materials are believed to have been disposed. At this time, Exelon and Generation do
not have sufficient information to assess this claim and therefore are unable to estimate a range of loss, if any. As such, no liability has been recorded for the
potential  contribution  claim.  It  is  reasonably  possible,  however,  that  resolution  of  this  matter  could  have  a  material,  unfavorable  impact  on  Exelon’s  and
Generation's financial statements.

In January 2018, the PRPs were advised by the EPA that it will begin an additional investigation and evaluation of groundwater conditions at the West Lake
Landfill. In September 2018, the PRPs agreed to an Administrative Settlement Agreement and Order on Consent for the performance by the PRPs of the
groundwater  Remedial  Investigation  (RI)/Feasibility  Study  (FS).  The  purpose  of  this  RI/FS  is  to  define  the  nature  and  extent  of  any  groundwater
contamination from the West Lake Landfill site and evaluate remedial alternatives. Generation estimates the undiscounted cost for the groundwater RI/FS to
be approximately $30 million. Generation determined a loss associated with the RI/FS is probable and has recorded a liability, included in the table above,
that reflects management’s best estimate of Cotter’s allocable share of the cost among the PRPs. At this time Generation cannot predict the likelihood that,
or  the  extent  to  which  any,  remediation  activities  may  be  required  and  therefore  cannot  estimate  a  reasonably  possible  range  of  loss  for  response  costs
beyond  those  associated  with  the  RI/FS  component.  It  is  reasonably  possible,  however,  that  resolution  of  this  matter  could  have  a  material,  unfavorable
impact on Exelon’s and Generation’s future financial statements.

In  August  2011,  Cotter  was  notified  by  the  DOJ  that  Cotter  is  considered  a  PRP  with  respect  to  the  government’s  clean-up  costs  for  contamination
attributable to low level radioactive residues at a former storage and reprocessing facility named Latty Avenue near St. Louis, Missouri. The Latty Avenue
site is included in ComEd’s (now Generation's) indemnification responsibilities discussed above as part of the sale of Cotter. The radioactive residues had
been  generated  initially  in  connection  with  the  processing  of  uranium  ores  as  part  of  the  U.S.  Government’s  Manhattan  Project.  Cotter  purchased  the
residues in 1969 for initial processing at the Latty Avenue facility for the subsequent extraction of uranium and metals. In 1976, the NRC found that the Latty
Avenue site had radiation levels exceeding NRC criteria for decontamination of land areas. Latty Avenue was investigated and remediated by the United
States Army Corps of Engineers pursuant to funding under FUSRAP. Pursuant to a series of annual agreements since 2011, the DOJ and the PRPs have
tolled the statute of limitations until August 31, 2021 so that settlement discussions can proceed. On August 3, 2020, the DOJ advised Cotter and the other
PRPs that it is seeking approximately $90 million from all the PRPs and has directed that the PRPs must submit a good faith joint proposed settlement offer.
Generation  has  determined  that  a  loss  associated  with  this  matter  is  probable  under  its  indemnification  agreement  with  Cotter  and  has  recorded  an
estimated liability, which is included in the table above.

Benning Road Site (Exelon, Generation, PHI, and Pepco). In September 2010, PHI received a letter from EPA identifying the Benning Road site as one of
six land-based sites potentially contributing to contamination of the lower Anacostia River. A portion of the site was formerly the location of a Pepco Energy
Services electric generating facility, which was deactivated in June 2012. The remaining portion of the site consists of a Pepco

transmission  and  distribution  service  center  that  remains  in  operation.  In  December  2011,  the  U.S.  District  Court  for  the  District  of  Columbia  approved  a
Consent Decree entered into by Pepco and Pepco Energy Services with the DOEE, which requires Pepco and Pepco Energy Services to conduct a RI/FS
for the Benning Road site and an approximately 10 to 15-acre portion of the adjacent Anacostia River.

Since 2013, Pepco and Pepco Energy Services (now Generation, pursuant to Exelon's 2016 acquisition of PHI) have been performing RI work and have
submitted  multiple  draft  RI  reports  to  the  DOEE.  In  September  2019,  Pepco  and  Generation  issued  a  draft  “final”  RI  report  which  DOEE  approved  on
February 3, 2020. Pepco and Generation are developing a FS to evaluate possible remedial alternatives for submission to DOEE. The Court has established
a schedule for completion of the FS, and approval by the DOEE, by September 16, 2021. After completion and approval of the FS, DOEE will prepare a
Proposed Plan for public comment and then issue a ROD identifying any further response actions determined to be necessary. PHI, Pepco, and Generation
have determined that a loss associated with this matter is probable and have accrued an estimated liability, which is included in the table above.

Anacostia River Tidal Reach (Exelon, PHI, and Pepco). Contemporaneous with the Benning Road site RI/FS being performed by Pepco and Generation,
DOEE and the National Park Service have been conducting a separate RI/FS focused on the entire tidal reach of the Anacostia River extending from just
north of the Maryland-District of Columbia boundary line to the confluence of the Anacostia and Potomac Rivers. The river-wide RI incorporated the results
of the river sampling performed by Pepco and Pepco Energy Services as part of the Benning RI/FS, as well as similar sampling efforts conducted by owners
of other sites adjacent to this segment of the river and supplemental river sampling conducted by DOEE’s contractor. In April 2018, DOEE released a draft RI
report for public review and comment. Pepco submitted written comments on the draft RI and participated in a public hearing.

Pepco has determined that it is probable that costs for remediation will be incurred and recorded a liability in the third quarter 2019 for management’s best
estimate of its share of those costs. On September 30, 2020, DOEE released its Interim ROD. The Interim ROD reflects an adaptive management approach
which  will  require  several  identified  “hot  spots”  in  the  river  to  be  addressed  first  while  continuing  to  conduct  studies  and  to  monitor  the  river  to  evaluate
improvements and determine potential future remediation plans. The adaptive management process chosen by DOEE is less intrusive, provides more long-
term environmental certainty, is less costly, and allows for site specific remediation plans already underway, including the plan for the Benning Road site to
proceed to conclusion. Pepco has concluded that incremental exposure remains reasonably possible, but management cannot reasonably estimate a range
of loss beyond the amounts recorded, which are included in the table above.

In addition to the activities associated with the remedial process outlined above, CERCLA separately requires federal and state (here including Washington,
D.C.) Natural Resource Trustees (federal or state agencies designated by the President or the relevant state, respectively, or Indian tribes) to conduct an
assessment of any damages to natural resources within their jurisdiction as a result of the contamination that is being remediated. The Trustees can seek
compensation  from  responsible  parties  for  such  damages,  including  restoration  costs.  During  the  second  quarter  of  2018,  Pepco  became  aware  that  the
Trustees  are  in  the  beginning  stages  of  a  Natural  Resources  Damages  (NRD)  assessment,  a  process  that  often  takes  many  years  beyond  the  remedial
decision to complete. Pepco has concluded that a loss associated with the eventual NRD assessment is reasonably possible. Due to the very early stage of
the assessment process, Pepco cannot reasonably estimate the range of loss.

Litigation and Regulatory Matters

Asbestos Personal Injury Claims (Exelon and Generation). Generation maintains a reserve for claims associated with asbestos-related personal injury
actions in certain facilities that are currently owned by Generation or were previously owned by ComEd and PECO. The estimated liabilities are recorded on
an undiscounted basis and exclude the estimated legal costs associated with handling these matters, which could be material.

At December 31, 2020 and 2019, Exelon and Generation recorded estimated liabilities of approximately $89 million and $83 million, respectively, in total for
asbestos-related  bodily  injury  claims.  As  of  December  31,  2020,  approximately  $25  million  of  this  amount  related  to  261  open  claims  presented  to
Generation, while the remaining $64 million is for estimated future asbestos-related bodily injury claims anticipated to arise through 2055, based on actuarial
assumptions and analyses, which are updated on an annual basis. On a quarterly

Note 19 — Commitments and Contingencies

basis, Generation monitors actual experience against the number of forecasted claims to be received and expected claim payments and evaluates whether
adjustments to the estimated liabilities are necessary.

It is reasonably possible that additional exposure to estimated future asbestos-related bodily injury claims in excess of the amount accrued could have a
material, unfavorable impact on Exelon’s and Generation’s financial statements. However, management cannot reasonably estimate a range of loss beyond
the amounts recorded.

Fund Transfer Restrictions (All Registrants). Under applicable law, Exelon may borrow or receive an extension of credit from its subsidiaries. Under the
terms of Exelon’s intercompany money pool agreement, Exelon can lend to, but not borrow from the money pool.

Under applicable law, Generation, ComEd, PECO, BGE, PHI, Pepco, DPL, and ACE can pay dividends only from retained, undistributed or current earnings.
A significant loss recorded at Generation, ComEd, PECO, BGE, PHI, Pepco, DPL, or ACE may limit the dividends that these companies can distribute to
Exelon.

ComEd has agreed in connection with financings arranged through ComEd Financing III that it will not declare dividends on any shares of its capital stock in
the  event  that:  (1)  it  exercises  its  right  to  extend  the  interest  payment  periods  on  the  subordinated  debt  securities  issued  to  ComEd  Financing  III;  (2)  it
defaults on its guarantee of the payment of distributions on the preferred trust securities of ComEd Financing III; or (3) an event of default occurs under the
Indenture under which the subordinated debt securities are issued. No such event has occurred.

PECO has agreed in connection with financings arranged through PEC L.P. and PECO Trust IV that PECO will not declare dividends on any shares of its
capital stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinated debentures, which were issued to PEC L.P.
or  PECO  Trust  IV;  (2)  it  defaults  on  its  guarantee  of  the  payment  of  distributions  on  the  Series  D  Preferred  Securities  of  PEC  L.P.  or  the  preferred  trust
securities of PECO Trust IV; or (3) an event of default occurs under the Indenture under which the subordinated debentures are issued. No such event has
occurred.

BGE is subject to restrictions established by the MDPSC that prohibit BGE from paying a dividend on its common shares if (a) after the dividend payment,
BGE’s equity ratio would be below 48% as calculated pursuant to the MDPSC’s ratemaking precedents or (b) BGE’s senior unsecured credit rating is rated
by two of the three major credit rating agencies below investment grade. No such event has occurred.

Pepco  is  subject  to  certain  dividend  restrictions  established  by  settlements  approved  in  Maryland  and  the  District  of  Columbia.  Pepco  is  prohibited  from
paying  a  dividend  on  its  common  shares  if  (a)  after  the  dividend  payment,  Pepco's  equity  ratio  would  be  48%  as  equity  levels  are  calculated  under  the
ratemaking precedents of the MDPSC and DCPSC or (b) Pepco’s senior unsecured credit rating is rated by one of the three major credit rating agencies
below investment grade. No such event has occurred.

DPL is subject to certain dividend restrictions established by settlements approved in Delaware and Maryland. DPL is prohibited from paying a dividend on
its common shares if (a) after the dividend payment, DPL's equity ratio would be 48% as equity levels are calculated under the ratemaking precedents of the
DPSC and MDPSC or (b) DPL’s senior unsecured credit rating is rated by one of the three major credit rating agencies below investment grade. No such
event has occurred.

ACE is subject to certain dividend restrictions established by settlements approved in New Jersey. ACE is prohibited from paying a dividend on its common
shares if (a) after the dividend payment, ACE's equity ratio would be 48% as equity levels are calculated under the ratemaking precedents of the NJBPU or
(b) ACE's senior unsecured credit rating is rated by one of the three major credit rating agencies below investment grade. ACE is also subject to a dividend
restriction  which  requires  ACE  to  obtain  the  prior  approval  of  the  NJBPU  before  dividends  can  be  paid  if  its  equity  as  a  percent  of  its  total  capitalization,
excluding securitization debt, falls below 30%. No such events have occurred.

City  of  Everett  Tax  Increment  Financing  Agreement  (Exelon  and  Generation).  On  April  10,  2017,  the  City  of  Everett  petitioned  the  Massachusetts
Economic Assistance Coordinating Council (EACC) to revoke the 1999 tax increment financing agreement (TIF Agreement) relating to Mystic Units 8 and 9
on the grounds that the total investment in Mystic Units 8 and 9 materially deviates from the investment set forth in the TIF Agreement. On October 31, 2017,
a three-member panel of the EACC conducted an administrative hearing on the City’s petition. On November 30, 2017, the hearing panel issued a tentative
decision denying the City’s petition, finding that

346

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 19 — Commitments and Contingencies

there was no material misrepresentation that would justify revocation of the TIF Agreement. On December 13, 2017, the tentative decision was adopted by
the full EACC. On January 12, 2018, the City filed a complaint in Massachusetts Superior Court requesting, among other things, that the court set aside the
EACC’s decision, grant the City’s request to decertify the Project and the TIF Agreement, and award the City damages for alleged underpaid taxes over the
period of the TIF Agreement. On January 8, 2020, the Massachusetts Superior Court affirmed the decision of the EACC denying the City's petition. The City
had until March 9, 2020 to appeal the decision and did not. As a result, the decision is final and the case is resolved. It is reasonably possible that property
taxes assessed in future periods, including those following the expiration of the TIF Agreement on June 30, 2020, could be material to Generation’s financial
statements.

Deferred Prosecution Agreement (DPA) and Related Matters (Exelon and ComEd). Exelon and ComEd received a grand jury subpoena in the second
quarter  of  2019  from  the  U.S.  Attorney’s  Office  for  the  Northern  District  of  Illinois  (USAO)  requiring  production  of  information  concerning  their  lobbying
activities in the State of Illinois. On October 4, 2019, Exelon and ComEd received a second grand jury subpoena from the USAO requiring production of
records of any communications with certain individuals and entities. On October 22, 2019, the SEC notified Exelon and ComEd that it had also opened an
investigation into their lobbying activities. On July 17, 2020, ComEd entered into a DPA with the USAO to resolve the USAO investigation. Under the DPA,
the USAO filed a single charge alleging that ComEd improperly gave and offered to give jobs, vendor subcontracts, and payments associated with those
jobs and subcontracts for the benefit of the Speaker of the Illinois House of Representatives and the Speaker’s associates, with the intent to influence the
Speaker’s action regarding legislation affecting ComEd’s interests. The DPA provides that the USAO will defer any prosecution of such charge and any other
criminal  or  civil  case  against  ComEd  in  connection  with  the  matters  identified  therein  for  a  three-year  period  subject  to  certain  obligations  of  ComEd,
including payment to the U.S. Treasury of $200 million, with $100 million payable within thirty days of the filing of the DPA with the United States District
Court for the Northern District of Illinois and an additional $100 million within ninety days of such filing date. The payments were recorded within Operating
and maintenance expense in Exelon’s and ComEd’s Consolidated Statements of Operations and Comprehensive Income in the second quarter of 2020. The
payments will not be recovered in rates or charged to customers and ComEd will not seek or accept reimbursement or indemnification from any source other
than Exelon. Exelon made equity contributions to ComEd of $200 million in 2020. On August 13, 2020, a motion was filed in the U.S. District Court for the
Northern District of Illinois by a ComEd customer and on behalf of ComEd customers seeking to enjoin ComEd from paying these funds to the U.S. Treasury
and requiring the U.S. government to establish a victims’ restitution fund from which the $200 million would be disbursed to ComEd customers. The motion
was denied without prejudice on November 6, 2020 and ComEd submitted the $200 million payment to the U.S. Treasury. On January 6, 2021, the customer
petitioned the Seventh Circuit for a writ of mandamus to seek review of the district court’s ruling, but on January 8, 2021, the Seventh Circuit denied the
petition. On January 22, 2021, the customer petitioned the Seventh Circuit for rehearing of its denial of his petition for a writ of mandamus. On February 5,
2021, the Seventh Circuit denied the petition for rehearing.

Exelon was not made a party to the DPA, and therefore the investigation by the USAO into Exelon’s activities ended with no charges being brought against
Exelon.

The SEC’s investigation remains ongoing and Exelon and ComEd have cooperated fully and intend to continue to cooperate fully with the SEC. Exelon and
ComEd  cannot  predict  the  outcome  of  the  SEC  investigation.  No  loss  contingency  has  been  reflected  in  Exelon's  and  ComEd's  consolidated  financial
statements with respect to the SEC investigation, as this contingency is neither probable nor reasonably estimable at this time.

Subsequent to Exelon announcing the receipt of the subpoenas, various lawsuits have been filed and various demand letters have been received related to
the subject of the subpoenas, the conduct described in the DPA and the SEC's investigation, including:

•

A  putative  class  action  lawsuit  against  Exelon  and  certain  officers  of  Exelon  and  ComEd  was  filed  in  federal  court  in  December  2019  alleging
misrepresentations and omissions in Exelon’s SEC filings related to ComEd’s lobbying activities and the related investigations. The complaint was
amended on September 16, 2020, to dismiss two of the original defendants and add other defendants, including ComEd. Defendants filed a motion
to dismiss in November 2020. Briefing was completed on February 17, 2021.

A derivative shareholder lawsuit was filed against Exelon, its directors and certain officers of Exelon and ComEd in April 2020 alleging, among other
things, breaches of fiduciary duties also purporting to relate to matters that are the subject of the subpoenas and the SEC investigation. The plaintiff
voluntarily dismissed this derivative action without prejudice to refile on July 28, 2020.

Three putative class action lawsuits against ComEd and Exelon were filed in Illinois state court in the third quarter of 2020 seeking restitution and
compensatory  damages  on  behalf  of  ComEd  customers.  These  three  state  cases  were  consolidated  into  a  single  action  in  October  of  2020.  In
addition, on November 2, 2020, the Citizens Utility Board (CUB) filed a motion to intervene in the state cases pursuant to an Illinois statute allowing
CUB to intervene as a party or otherwise participate on behalf of utility consumers in any proceeding which affects the interest of utility consumers.
On  November  23,  2020,  the  court  allowed  CUB’s  intervention,  but  denied  CUB’s  request  to  stay  these  cases.  Plaintiffs  subsequently  filed  a
consolidated complaint, and ComEd and Exelon filed a motion to dismiss on jurisdictional and substantive grounds on January 11, 2021. Briefing on
that motion is ongoing.

Four putative class action lawsuits against ComEd and Exelon were filed in federal court in the third quarter of 2020 alleging, among other things,
civil violations of federal racketeering laws. In addition, CUB filed a motion to intervene in these cases on October 22, 2020 which was granted on
December 23, 2020. In addition, on December 2, 2020, the court appointed interim lead plaintiffs in the federal cases which consisted of counsel for
three of the four federal cases. These plaintiffs filed a consolidated complaint on January 5, 2021. CUB also filed its own complaint against ComEd
only on the same day. The remaining federal case, Potter, et al. v. Exelon et al, differed from the other lawsuits as it named additional individual
defendants not named in the consolidated complaint. On January 10, 2021, the Potter plaintiffs filed a motion asking the court to clarify that their
class action complaint against ComEd, Exelon and the individual named defendants remains in effect, notwithstanding the consolidated amended
complaint,  and  asked  the  court  to  stay  the  Potter  case.  On  January  21,  2021,  the  court  determined  that  the  appointed  lead  counsel  had  sole
discretion to determine which parties to name as plaintiffs and defendants, and that the Potter plaintiffs have the option to opt-out of that class and
file a separate, individual action against the defendants named in their original complaint. The Potter plaintiffs have until March 23, 2021 to make
that decision.

Four  shareholders  sent  letters  to  the  Exelon  Board  of  Directors  in  2020  demanding,  among  other  things,  that  the  Exelon  Board  of  Directors
investigate and address alleged breaches of fiduciary duties and other alleged violations by Exelon and ComEd officers and directors related to the
conduct described in the DPA.

No loss contingencies have been reflected in Exelon’s and ComEd’s consolidated financial statements with respect to these matters, as such contingencies
are neither probable nor reasonably estimable at this time.

General (All Registrants). The Registrants are involved in various other litigation matters that are being defended and handled in the ordinary course of
business. The assessment of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often involves a series
of complex judgments about future events. The Registrants maintain accruals for such losses that are probable of being incurred and subject to reasonable
estimation. Management is sometimes unable to estimate an amount or range of reasonably possible loss, particularly where (1) the damages sought are
indeterminate, (2) the proceedings are in the early stages, or (3) the matters involve novel or unsettled legal theories. In such cases, there is considerable
uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss.

21. Stock-Based Compensation Plans (All Registrants)

Stock-Based Compensation Plans

Exelon  grants  stock-based  awards  through  its  LTIP,  which  primarily  includes  performance  share  awards,  restricted  stock  units,  and  stock  options.  At
December 31, 2020, there were approximately 34 million shares authorized for issuance under the LTIP. For the years ended December 31, 2020, 2019, and
2018, exercised and distributed stock-based awards were primarily issued from authorized but unissued common stock shares.

The  Registrants  grant  cash  awards.  The  following  table  does  not  include  expense  related  to  these  plans  as  they  are  not  considered  stock-based
compensation plans under the applicable authoritative guidance.

Exelon receives a tax deduction based on the intrinsic value of the award on the exercise date for stock options and the distribution date for performance
share awards and restricted stock units. For each award, throughout the requisite service period, Exelon recognizes the tax benefit related to compensation
costs. The following table presents information regarding Exelon’s realized tax benefit when distributed:

Performance share awards are granted under the LTIP. The performance share awards are settled 50% in common stock and 50% in cash at the end of the
three-year  performance  period,  except  for  awards  granted  to  vice  presidents  and  higher  officers  that  are  settled  100%  in  cash  if  certain  ownership
requirements are satisfied.

The common stock portion of the performance share awards is considered an equity award and is valued based on Exelon's stock price on the grant date.
The cash portion of the performance share awards is considered a liability award which is remeasured each reporting period based on Exelon’s current stock
price. As the value of the common stock and cash portions of the awards are based on Exelon’s stock price during the performance period, coupled with
changes  in  the  total  shareholder  return  modifier  and  expected  payout  of  the  award,  the  compensation  costs  are  subject  to  volatility  until  payout  is
established.

For nonretirement-eligible employees, stock-based compensation costs are recognized over the vesting period of three years using the straight-line method.
For performance share awards granted to retirement-eligible employees, the value of the performance shares is recognized ratably over the vesting period,
which is the year of grant.

Exelon processes forfeitures as they occur for employees who do not complete the requisite service period.

The following table summarizes Exelon’s nonvested performance share awards activity:

Restricted Stock Units

Restricted stock units are granted under the LTIP with the majority being settled in a specific number of shares of common stock after the service condition
has been met. The corresponding cost of services is measured based on the grant date fair value of the restricted stock unit issued.

The value of the restricted stock units is expensed over the requisite service period using the straight-line method. The requisite service period for restricted
stock  units  is  generally  three  to  five  years.  However,  certain  restricted  stock  unit  awards  become  fully  vested  upon  the  employee  reaching  retirement-
eligibility. The value of the restricted stock units granted to retirement-eligible employees is either recognized ratably over the first six months in the year of
grant if the employee reaches retirement eligibility prior to July 1st of the grant year or through the date of which the employee reaches retirement eligibility.
Exelon processes forfeitures as they occur for employees who do not complete the requisite service period.

Non-qualified stock options to purchase shares of Exelon’s common stock were granted through 2012 under the LTIP. The exercise price of the stock options
is equal to the fair market value of the underlying stock on the date of option grant. Stock options will expire no later than ten years from the date of grant.

At December 31, 2020 all stock options were vested and there were no unrecognized compensation costs.

At December 31, 2020 and 2019, Exelon, Generation, PHI, and ACE collectively consolidated several VIEs or VIE groups for which the applicable Registrant
was the primary beneficiary (see Consolidated VIEs below) and had significant interests in several other VIEs for which the applicable Registrant does not
have  the  power  to  direct  the  entities’  activities  and,  accordingly,  was  not  the  primary  beneficiary  (see  Unconsolidated  VIEs  below).  Consolidated  and
unconsolidated VIEs are aggregated to the extent that the entities have similar risk profiles.

As of December 31, 2020 and 2019, Exelon's and Generation's consolidated VIEs consist of:

Consolidated VIE or VIE groups:

Reason entity is a VIE:

Reason Generation is primary beneficiary:

CENG - A joint venture between Generation and EDF.
Generation has a 50.01% equity ownership in CENG. See
additional discussion below.

Disproportionate relationship between equity interest and
operational control as a result of the NOSA described further
below.

EGRP - A collection of wind and solar project entities.
Generation has a 51% equity ownership in EGRP. See
additional discussion below.

Similar structure to a limited partnership and the limited
partners do not have kick out rights with respect to the general
partner.

Bluestem Wind Energy Holdings, LLC - A Tax Equity structure
which is consolidated by EGRP. Generation is a minority
interest holder.

Similar structure to a limited partnership and the limited
partners do not have kick out rights with respect to the general
partner.

Generation conducts the operational activities.

Generation conducts the operational activities.

Generation conducts the operational activities.

The PPA contract absorbs variability through a performance
guarantee.

Generation conducts all activities.

Similar structure to a limited partnership and the limited
partners do not have kick out rights with respect to the general
partner.

Generation conducts the operational activities.

Equity capitalization is insufficient to support its operations.

Generation conducts all activities.

Antelope Valley - A solar generating facility, which is 100%
owned by Generation. Antelope Valley sells all of its output to
PG&E through a PPA.

Equity investment in distributed energy company - Generation
has a 31% equity ownership. This distributed energy company
has an interest in an unconsolidated VIE. (See
Unconsolidated VIEs disclosure below).

Generation fully impaired this investment in the third quarter of
2019. Refer to Note 12 — Asset Impairments for additional
information.

NER - A bankruptcy remote, special purpose entity which is
100% owned by Generation, which purchases certain of
Generation’s customer accounts receivable arising from the
sale of retail electricity.

NER’s assets will be available first and foremost to satisfy the
claims of the creditors of NER. Refer to Note 6 —Accounts
Receivable for additional information on the sale of
receivables.

CENG - On April 1, 2014, Generation, CENG, and subsidiaries of CENG executed the NOSA pursuant to which Generation conducts all activities associated
with the operations of the CENG fleet and provides corporate and administrative services to CENG and the CENG fleet for the remaining life of the CENG
nuclear plants as if they were a part of the Generation nuclear fleet, subject to the CENG member rights of EDF.

EDF  has  the  option  to  sell  its  49.99%  equity  interest  in  CENG  to  Generation.  On  November  20,  2019,  Generation  received  notice  of  EDF's  intention  to
exercise  the  put  option  to  sell  its  interest  in  CENG  to  Generation  and  the  put  automatically  exercised  on  January  19,  2020.  Refer  to  Note  2  —  Mergers,
Acquisitions, and Dispositions for additional information.

Exelon and Generation, where indicated, provide the following support to CENG:

355

Table of Contents

Combined Notes to Consolidated Financial Statements
(Dollars in millions, except per share data unless otherwise noted)

Note 23 — Variable Interest Entities

•

•

•

Generation executed an Indemnity Agreement pursuant to which Generation agreed to indemnify EDF against third-party claims that may arise
from any future nuclear incident (as defined in the Price-Anderson Act) in connection with the CENG nuclear plants or their operations. Exelon
guarantees Generation’s obligations under this Indemnity Agreement. See Note 19 — Commitments and Contingencies for more details,

Generation  and  EDF  share  in  the  $688  million  of  contingent  payment  obligations  for  the  payment  of  contingent  retrospective  premium
adjustments for the nuclear liability insurance, and

Exelon  has  executed  an  agreement  to  provide  up  to  $245  million  to  support  the  operations  of  CENG  as  well  as  a  $165  million  guarantee  of
CENG’s cash pooling agreement with its subsidiaries.

EGRP - EGRP is a collection of wind and solar project entities and some of these project entities are VIEs that are consolidated by EGRP. Generation owns
a number of limited liability companies that build, own, and operate solar and wind power facilities some of which are owned by EGRP. While Generation or
EGRP owns 100% of the solar entities and 100% of the majority of the wind entities, it has been determined that certain of the solar and wind entities are
VIEs because the entities require additional subordinated financial support in the form of a parental guarantee of debt, loans from the customers in order to
obtain  the  necessary  funds  for  construction  of  the  solar  facilities,  or  the  customers  absorb  price  variability  from  the  entities  through  the  fixed  price  power
and/or REC purchase agreements. Generation is the primary beneficiary of these solar and wind entities that qualify as VIEs because Generation controls
the design, construction, and operation of the facilities. There is limited recourse to Generation related to certain solar and wind entities.

In 2017, Generation’s interests in EGRP were contributed to and are pledged for the EGR IV non-recourse debt project financing structure. Refer to Note 17
— Debt and Credit Agreements for additional information.

As of December 31, 2020 and 2019, Exelon's, PHI's and ACE's consolidated VIE consists of:

Consolidated VIEs:

Reason entity is a VIE:

Reason ACE is the primary beneficiary:

ACE Funding - A special purpose entity formed by ACE for the purpose of
securitizing authorized portions of ACE’s recoverable stranded costs through the
issuance and sale of Transition Bonds. Proceeds from the sale of each series of
Transition Bonds by ATF were transferred to ACE in exchange for the transfer by
ACE to ATF of the right to collect a non-bypassable Transition Bond Charge from
ACE customers pursuant to bondable stranded costs rate orders issued by the
NJBPU in an amount sufficient to fund the principal and interest payments on
Transition Bonds and related taxes, expenses, and fees.

Unconsolidated VIEs

ACE’s equity investment is a variable interest
as, by design, it absorbs any initial variability
of ATF. The bondholders also have a variable
interest for the investment made to purchase
the Transition Bonds.

ACE controls the servicing activities.

Exelon’s and Generation’s variable interests in unconsolidated VIEs generally include equity investments and energy purchase and sale contracts. For the
equity investments, the carrying amount of the investments is reflected in Exelon’s and Generation’s Consolidated Balance Sheets in Investments. For the
energy  purchase  and  sale  contracts  (commercial  agreements),  the  carrying  amount  of  assets  and  liabilities  in  Exelon’s  and  Generation’s  Consolidated
Balance Sheets that relate to their involvement with the VIEs are predominately related to working capital accounts and generally represent the amounts
owed by, or owed to, Exelon and Generation for the deliveries associated with the current billing cycles under the commercial agreements.

As of December 31, 2020 and 2019, Exelon and Generation had significant unconsolidated variable interests in several VIEs for which Exelon or Generation,
as applicable, was not the primary beneficiary. These interests include certain equity method investments and certain commercial agreements.

__________
(a) At December 31, 2020 and 2019, Generation also had a contract liability with ComEd for $50 million and $37 million, respectively, that was included in Other liabilities on
Generation’s Consolidated Balance Sheets. At December 31, 2020 and 2019, ComEd had a Current Payable to Generation of $28 million and $41 million, respectively, on
its Consolidated Balance Sheets, which consisted of Generation’s Current Receivable from ComEd, partially offset by Generation’s contract liability with ComEd.

Borrowings from Exelon/PHI intercompany money pool

To provide an additional short-term borrowing option that will generally be more favorable to the borrowing participants than the cost of external financing
both Exelon and PHI operate an intercompany money pool. Generation, ComEd, PECO, and PHI Corporate participate in the Exelon money pool. Pepco,
DPL, and ACE participate in the PHI intercompany money pool.

Noncurrent Receivables from/Payables to affiliates

Generation has long-term payables to ComEd and PECO as a result of the nuclear decommissioning contractual construct whereby, to the extent NDT funds
are greater than the underlying ARO at the end of decommissioning, such amounts are due back to ComEd and PECO, as applicable, for payment to their
respective customers. See Note 10 — Asset Retirement Obligations for additional information.

Note 25 — Related Party Transactions

In connection with the debt obligations assumed by Exelon as part of the Constellation merger, Exelon and subsidiaries of Generation (former Constellation
subsidiaries)  assumed  intercompany  loan  agreements  that  mirror  the  terms  and  amounts  of  the  third-party  debt  obligations  of  Exelon,  resulting  in
intercompany  notes  payable  included  in  Long-term  debt  to  affiliates  in  Generation’s  Consolidated  Balance  Sheets  and  intercompany  notes  receivable  at
Exelon Corporate.

26. Subsequent Events (Exelon and Generation)

Planned Separation

On  February  21,  2021,  Exelon’s  Board  of  Directors  approved  a  plan  to  separate  the  Utility  Registrants  and  Generation,  creating  two  publicly  traded
companies. Under the separation plan, Exelon shareholders will retain their current shares of Exelon stock and receive a pro-rata distribution of shares of the
new company’s stock in a transaction that is expected to be tax-free to Exelon and its shareholders for U.S. federal income tax purposes. The actual number
of shares to be distributed to Exelon shareholders will be determined prior to closing.

Exelon is targeting to complete the separation in the first quarter of 2022, subject to final approval by Exelon’s Board of Directors, a Form 10 registration
statement  being  declared  effective  by  the  SEC,  regulatory  approvals,  and  satisfaction  of  other  conditions.  The  transaction  is  subject  to  approval  by  the
FERC, NRC, and NYPSC, and receipt of a private letter ruling from the IRS and tax opinion from Exelon’s tax advisors. There can be no assurance that any
separation transaction will ultimately occur or, if one does occur, of its terms or timing.

Impacts of February 2021 Weather Events and Texas-based Generating Assets Outages

Beginning on February 15, 2021, Generation’s Texas-based generating assets within the ERCOT market, specifically Colorado Bend II, Wolf Hollow II, and
Handley,  experienced  periodic  outages  as  a  result  of  historically  severe  cold  weather  conditions.  In  addition,  those  weather  conditions  drove  increased
demand for service, limited the availability of natural gas to fuel power plants, dramatically increased wholesale power prices, and also increased gas prices
in  certain  regions.  In  response  to  the  high  demand  and  significantly  reduced  total  generation  on  the  system,  ERCOT  implemented  load  reductions  to
maintain the reliability of the grid and required the use of an administrative price cap of $9,000 per megawatt hour during load shedding events.

Exelon  and  Generation  estimate  the  impact  to  their  Net  income  for  the  first  quarter  of  2021  arising  from  these  market  and  weather  conditions  to  be
approximately $560 million to $710 million. The estimated impact includes favorable results in certain regions within Generation’s wholesale gas business.
The ultimate impact to Exelon’s and Generation’s consolidated financial statements may be affected by a number of factors, including final settlement data,
the impacts of customer and counterparty credit losses, any state sponsored solutions to address the financial challenges caused by the event, and litigation
and contract disputes which may result.

Generation used a combination of commercial paper and letters of credit to manage collateral needs and has posted approximately $1.4 billion of collateral
with ERCOT as of February 22, 2021. Generation continues to believe it has sufficient cash on hand and available capacity on its revolver, which was $2.4
billion as of February 22, 2021, to meet its liquidity requirements.

ITEM 9.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

All Registrants

None.

ITEM 9A.

CONTROLS AND PROCEDURES

All Registrants—Disclosure Controls and Procedures

During  the  fourth  quarter  of  2020,  each  registrant’s  management,  including  its  principal  executive  officer  and  principal  financial  officer,  evaluated  the
effectiveness of that registrant’s disclosure controls and procedures

368

Table of Contents

related to the recording, processing, summarizing, and reporting of information in that registrant’s periodic reports that it files with the SEC. These disclosure
controls  and  procedures  have  been  designed  by  each  registrant  to  ensure  that  (a)  information  relating  to  that  registrant,  including  its  consolidated
subsidiaries,  that  is  required  to  be  included  in  filings  under  the  Securities  Exchange  Act  of  1934,  is  accumulated  and  made  known  to  that  registrant’s
management, including its principal executive officer and principal financial officer, by other employees of that registrant and its subsidiaries as appropriate to
allow timely decisions regarding required disclosure, and (b) this information is recorded, processed, summarized, evaluated, and reported, as applicable,
within the time periods specified in the SEC’s rules and forms. Due to the inherent limitations of control systems, not all misstatements may be detected.
These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or
mistake. Additionally, controls could be circumvented by the individual acts of some persons or by collusion of two or more people.

Accordingly,  as  of  December  31,  2020,  the  principal  executive  officer  and  principal  financial  officer  of  each  registrant  concluded  that  such  registrant’s
disclosure controls and procedures were effective to accomplish their objectives.

All Registrants—Changes in Internal Control Over Financial Reporting

Each registrant continually strives to improve its disclosure controls and procedures to enhance the quality of its financial reporting and to maintain dynamic
systems that change as conditions warrant. However, there have been no changes in internal control over financial reporting that occurred during the fourth
quarter  of  2020  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  any  of  the  Registrant's  internal  control  over  financial  reporting,
including no changes resulting from COVID-19. See ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS - Executive Overview for additional information on COVID-19.

All Registrants—Internal Control Over Financial Reporting

Management is required to assess and report on the effectiveness of its internal control over financial reporting as of December 31, 2020. As a result of that
assessment, management determined that there were no material weaknesses as of December 31, 2020 and, therefore, concluded that each registrant’s
internal control over financial reporting was effective. Management’s Report on Internal Control Over Financial Reporting is included in ITEM 8. FINANCIAL
STATEMENTS AND SUPPLEMENTARY DATA.

(1) Balance includes stock options, unvested performance shares, and unvested restricted stock units that were granted under the Exelon LTIP or predecessor company plans
(including  shares  awarded  under  those  plans  and  deferred  into  the  stock  deferral  plan)  and  deferred  stock  units  granted  to  directors  as  part  of  their  compensation.
Unvested performance shares are subject to performance metrics and to a total shareholder return modifier. Additionally, pursuant to the terms of the Exelon LTIP plan,
50% of final payouts are made in the form of shares of common stock and 50% is made in form of in cash, or if the participant has exceeded 200% of their stock ownership
requirement, 100% of the final payout is made in cash. For performance shares granted in 2018, 2019, and 2020, the total includes the maximum number of shares that
could  be  issued  assuming  all  participants  receive  50%  of  payouts  in  shares  and  assuming  the  performance  and  total  shareholder  return  modifier  metrics  were  both  at
maximum,  representing  best  case  performance,  for  a  total  of  6,988,082  shares.  If  the  performance  and  total  shareholder  return  modifier  metrics  were  at  "target",  the
number of securities to be issued for such awards would be 3,494,041. The balance also includes 450,154 shares to be issued upon the conversion of deferred stock units
awarded to members of the Exelon board of directors. Conversion of the deferred stock units to shares of common stock occurs after a director terminates service to the
Exelon  board  or  the  board  of  any  of  its  subsidiary  companies.  See  Note  21  —  Stock-Based  Compensation  Plans  of  the  Combined  Notes  to  Consolidated  Financial

Commonwealth Edison Company

ARTICLE I

MEETINGS OF SHAREHOLDERS

Section 1. - Annual Meeting.

The annual meeting of the shareholders for the election of Directors and for the transaction of general business shall be
held on any date as determined year to year by the Board of Directors. The time and location of the meeting shall be determined
by the Board of Directors.

Section 2. - Special Meeting.

Special meetings of the shareholders may be held upon call by the Chair of the Board, if one is elected, the President, or
a majority of the Board of Directors whenever they deem expedient, or upon the written request of the holders of shares entitled
to not less than twenty percent of all the votes entitled to be cast at such a meeting.

Section 3. - Notice of Meetings

Written or printed notice of every meeting of the shareholders, whether annual or special, stating the place, day, and hour
of such meeting and (in the case of special meetings) the business proposed to be transacted shall be given by the Secretary to
each shareholder entitled to vote at such meeting not less than ten (10) days but no more than sixty (60) days before the date
fixed for such meeting, by electronic mail at his or her e-mail address as it appears on the records of the Company or by
depositing such notice in the United States mail addressed to him or her at his or her post office address as it appears on the
records of the Company, with postage thereon prepaid. A written waiver of notice of a meeting of the shareholders, signed by
the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the
giving of the notice.

Section 4. - Organization of Meeting.

All meetings of the shareholders shall be called to order by the Chair of the Board, or if one is not elected or is absent, by
the  President,  or  in  his  or  her  absence  by  a  Vice  President,  or  in  the  case  of  the  absence  of  such  officers,  then  by  any
shareholder, whereupon the meeting shall organize by electing a Chair. The Secretary of the Company, if present, shall act as
secretary of the meeting, unless some other person shall be elected by the meeting to so act. An accurate record of the meeting
shall be kept by the secretary thereof, and placed in the record books of the Company.

Section 5. - Quorum.

At any meeting of the shareholders, the presence in person or by proxy of shareholders entitled to cast a majority of the
votes that all shareholders are entitled to cast on a particular matter to be acted upon at the meeting shall constitute a quorum
for the transaction of business. If a quorum be not present at any meeting, holders of a majority of the shares of stock so present
or represented may adjourn the meeting either sine die or to a date certain.

1

Section 6. - Voting.

At  all  meetings  of  the  shareholders,  each  shareholder  shall  be  entitled  to  one  vote  for  each  share  of  common  stock
standing in his or her name and, when the preferred or preference stock is entitled to vote, such number of votes as shall be
provided in the charter of the Company for each share of preferred and preference stock standing in his or her name, and the
votes shall be cast by shareholders in person or by lawful proxy.

Section 7. - Action by Consent

    Any action required or permitted by law, the Articles of Incorporation, or these Amended and Restated Bylaws to be taken at a
meeting of the shareholders of the Company may be taken without a meeting if a consent or consents in writing, setting forth the
action  so  taken,  shall  be  signed  by  shareholders  holding  at  least  a  majority  of  the  voting  power;  provided  that  if  a  different
proportion of voting power is required for such an action at a meeting, then that proportion of written consents is required.  Such
signed consent shall be delivered to the Secretary for inclusion in the minute book of the Corporation.

Section 8. - Record Date for Shareholders and Closing of Transfer Books.

The  Board  of  Directors  may  fix,  in  advance,  a  date  as  the  record  for  the  determination  of  the  shareholders  entitled  to
notice of, or to vote at, any meeting of shareholders, or entitled to receive payment of any dividend, or entitled to the allotment of
any rights, or for any other proper purpose. Such date in any case shall not be more than sixty (60) days (and in the case of a
meeting of shareholders not less than ten (10) days) prior to the date on which the particular action requiring such determination
of shareholders is to be taken. Only shareholders of record on such date shall be entitled to notice of or to vote at such meeting
or to receive such dividends or rights, as the case may be.

Section 9. – Voting Lists.

        The  Secretary  of  the  Company  shall  make,  within  twenty  days  after  the  record  date  for  a  meeting  of  stockholders  of  the
Company  or  ten  days  before  such  meeting,  whichever  is  earlier,  a  complete  list  of  the  stockholders  entitled  to  vote  at  such
meeting, arranged in alphabetical order, with the address of and the number of shares held by each, which list, for at least ten
days prior to such meeting, shall be kept on file at the registered office of the Company and shall be subject to inspection by any
stockholder,  and  to  copying  at  such  stockholder's  expense,  at  any  time  during  usual  business  hours.  Such  list  shall  also  be
produced and kept open at the time and place of the meeting and shall be subject to the inspection of any stockholder during the
whole time of the meeting.

ARTICLE II

BOARD OF DIRECTORS AND COMMITTEES

Section 1. - Powers of Directors.

The business and affairs of the Company shall be managed by a Board of Directors which shall have and may exercise

will be no less than four (4) Directors or more than nine (9) Directors.

(b)    At least one (1) member of the Board of Directors must be an “Independent Director”, which is defined to mean that

Section 3. - Removals and Vacancies.

The shareholders, at any meeting duly called and at which a quorum is present or by written consent in lieu thereof, may
remove any Director or Directors from office by the affirmative vote of the holders of a majority of the outstanding shares entitled
to  the  vote  thereon.  Vacancies  occurring  in  the  Board  of  Directors  for  any  reason  may  be  filled  by  the  affirmative  vote  of  the
holders of a majority of the outstanding shares entitled to vote thereon.

Section 4. - Director Retirement Age

        Each  Independent  Director  must  retire  from  the  Board  of  Directors  at  or  before  the  next  annual  meeting  of  shareholders
following the director’s 75th birthday; provided, however, that a Director’s continued service may be extended by resolution of a
majority of the Company’s shareholders.

Section 5. - Chair of the Board of Directors; Vice Chair.

The Chair of the Board of Directors, if one is elected, shall preside at all meetings of the Board of Directors and of the
shareholders,  and  shall  also  have  such  other  powers  and  duties  as  from  time  to  time  may  be  assigned  to  him  or  her  by  the

represented by a certificate as the Board of Directors and the law of the State of Illinois may, from time to time, require.

Section 3. - Lost, Stolen or Destroyed Certificates.

No certificate for shares of stock of the Company shall be issued in place of any other certificate alleged to have been

(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely

to adversely affect the registrant’s ability to record, process, summarize and report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal control over

financial reporting.
