Merger with Pepco Holdings, Inc. (Exelon)

On March 23, 2016, Exelon completed the merger contemplated by the Merger Agreement 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.

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.

Acquisitions and Dispositions

Disposition of Oyster Creek. On July 1, 2019, Generation completed the sale with Holtec International (Holtec) and its indirect wholly owned subsidiary, Oyster
Creek  Environmental  Protection,  LLC  (OCEP),  of  Oyster  Creek  located  in  Forked  River,  New  Jersey,  which  permanently  ceased  generation  operations  on
September 17, 2018.

Disposition of EGTP and Acquisition of Handley Generating Station. On November 7, 2017, EGTP and all of its wholly owned subsidiaries filed voluntary
petitions for relief under Chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware. As a result of the
bankruptcy filing, EGTP’s assets and liabilities were deconsolidated from Exelon and Generation's consolidated financial statements. The Chapter 11 bankruptcy
proceedings  were  finalized  on  April  17,  2018,  resulting  in  the  ownership  of  EGTP  assets  (other  than  the  Handley  Generating  Station)  being  transferred  to
EGTP's lenders.

On April 4, 2018, Generation acquired the Handley Generating Station in conjunction with the EGTP Chapter 11 proceedings for a total purchase price of $62
million.

Acquisition  of  FitzPatrick.  On  March  31,  2017,  Generation  acquired  the  single-unit  FitzPatrick  plant  located  in  Scriba,  New  York  from  Entergy  for  a  total
purchase price consideration of $289 million, resulting in an after-tax bargain purchase gain of $233 million in 2017.

Acquisition  of  ConEdison  Solutions.  On  September  1,  2016,  Generation  acquired  ConEdison  Solutions  for  a  purchase  price  of  $257  million,  including  net
working capital of $204 million. The renewable energy, sustainable services and energy efficiency businesses of ConEdison were excluded from the transaction.

See  Note  2 —  Mergers,  Acquisitions  and  Dispositions and  Note  11 —  Asset Impairments of  the  Combined  Notes  to  Consolidated  Financial  Statements  for

Nuclear Facilities

Generation  has  ownership  interests  in  thirteen  nuclear  generating  stations  currently  in  service,  consisting  of  23  units  with  an  aggregate  of  18,872 MW  of
capacity. 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.

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. 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 transaction will require
approval of the NYPSC, the FERC and the NRC. The process and regulatory approvals could take one to two years or more to complete.

See ITEM 2. PROPERTIES for  additional  information  on  Generation's  nuclear  facilities  and  Note  22 —  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 2019, 2018 and 2017 electric supply (in GWh) generated from the nuclear generating
facilities  was  64%, 68% and  69%,  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.

During 2019, 2018 and 2017, the nuclear generating facilities operated by Generation achieved capacity factors of 95.7%, 94.6% and 94.1%, respectively. The
capacity  factors  reflect  ownership  percentage  of  stations  operated  by  Generation.  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.

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, the regulations

10

Table of Contents

under  such  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. Additionally, PSEG has received 20-year operating license renewals for Salem Units 1 and 2.

__________
(a) Denotes year in which nuclear unit began commercial operations.
(b) Although timing has been delayed, Generation currently plans to seek license renewal for Clinton and has notified the NRC that any license renewal application would not

be filed until the first quarter of 2024. In 2019, the NRC approved a change of the operating license expiration for Clinton from 2026 to 2027.

(c) On July 10, 2018, Generation submitted a second 20-year license renewal application to NRC for Peach Bottom Units 2 and 3. See Note  3 - Regulatory Matters of the

Combined Notes to Consolidated Financial Statements for additional information.

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. To date, each granted license renewal has
been for 20 years beyond the original operating license expiration. 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 and Peach Bottom. 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

11

useful life of 2053 and 2054 for Unit 2 and Unit 3, respectively, which reflects the anticipated second renewal of its operating licenses. See Note 3 — Regulatory
Matters of the Combined Notes to Consolidated Financial Statements for additional information on FEJA and Note 6 — Early Plant Retirements of the Combined
Notes to Consolidated Financial Statements for additional information on early retirements.

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, 2019, Generation had approximately 84,700 SNF assemblies (21,000 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 18 — 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 until after 2020.

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  18 —  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.

12

Table of Contents

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 NDTs. At December 31,
2019 the  fair  value  of  NDTs  exceeds  the  balance  of  the  Nuclear  AROs.  See  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION  AND  RESULTS  OF  OPERATIONS —  Exelon Corporation, Executive Overview; ITEM 7. MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF
FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS,  Critical  Accounting  Policies  and  Estimates,  Nuclear  Decommissioning,  Asset  Retirement
Obligations and Nuclear Decommissioning Trust Fund Investments; and Note 3 — Regulatory Matters, Note 2 — Mergers, Acquisitions and Dispositions, Note
17 — Fair Value of Financial Assets and Liabilities and Note 9 — Asset Retirement Obligations of the Combined Notes to Consolidated Financial Statements for
additional information regarding Generation’s NDT funds and its decommissioning obligations.

Zion Station Decommissioning. On September 1, 2010, Generation completed an Asset Sale Agreement (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 9 —
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 22 —  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 2019, 2018 and 2017, electric supply (in GWh) generated from
owned  fossil  and  renewable  generating  facilities  was  11%, 11% and  12%,  respectively,  of  Generation’s  total  electric  supply.  The  majority  of  this  output  was
dispatched  to  support  Generation’s  wholesale  and  retail  power  marketing  activities.  For  additional  information  regarding  Generation’s  electric  generating
facilities, see ITEM 2. PROPERTIES.

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.

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 16 — 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 — Exelon Generation Company, LLC.

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 2019 and 2018 includes physical volumes of 35,745 GWh and 35,100 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 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial
Statements for additional information regarding derivative financial instruments.

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

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

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 2020 and beyond for portions of its electricity portfolio that are unhedged.
As  of  December  31,  2019,  the  percentage  of  expected  generation  hedged  for  the  Mid-Atlantic,  Midwest,  New  York  and  ERCOT  reportable  segments  is
91%-94% and  61%-64% for  2020 and  2021,  respectively.  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 2020 includes 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 2020 capital expenditures.

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.

Table of Contents

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.

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 electric distribution revenues and natural gas distribution revenues,  ACE’s electric distribution revenues and DPL’s Delaware electric distribution and
natural gas 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 are recovered through traditional rate case proceedings.  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’ Revenues net of
purchased power and fuel expense, which is a non-GAAP measure used to evaluate operational performance, or 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-Related Proceedings

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

17

Table of Contents

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,  129,000 mmcf and  58,000 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:

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 2020 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

18

 
 
 
 
Table of Contents

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-access  basis  using  the  transmission  facilities  of  the  PJM  transmission  owners  at  rates  based  on  the  costs  of  transmission
service.

The Utility Registrants' transmission rates are established based on a formula that was approved by FERC as shown below:

Environmental Regulation

General

The Registrants are subject to comprehensive and complex legislation regarding environmental matters by the federal government and various state and local
jurisdictions in which they operate their facilities. The Registrants are also subject to environmental regulations administered by the EPA and various state and
local environmental protection agencies. Federal, state and local regulation includes the authority to regulate air, water, and solid and hazardous waste disposal.

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 Director, Safety & Sustainability, 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 Governance Committee the authority to
oversee

19

 
 
 
 
 
 
Table of Contents

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.

Air Quality

Air quality regulations promulgated by the EPA and the various state and local environmental agencies impose restrictions on emission of particulates, sulfur
dioxide (SO2), nitrogen oxides (NOx), mercury and other air pollutants and require permits for operation of emitting sources. Such permits have been obtained
as  needed  by  Exelon’s  subsidiaries.  However,  due  to  its  low  emitting  generation  fleet  comprised  of  nuclear,  natural  gas,  hydroelectric,  wind  and  solar,
compliance with the Federal Clean Air Act does not have a material impact on Generation’s operations.

See  ITEM  7.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF  OPERATIONS for  additional  information
regarding clean air regulation in the forms of the CSAPR, regulation of hazardous air pollutants from coal- and oil-fired electric generating facilities under MATS,
and regulation of GHG emissions.

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  must  be  renewed  periodically.  Certain  of  Exelon's  facilities discharge  stormwater  and  industrial
wastewater  into  waterways  and  are  therefore  subject  to  these  regulations  and  operate  under  NPDES  permits  or  pending  applications  for  renewals  of  such
permits  after  being  granted  an  administrative  extension.  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.

Section 316(b) of the Clean Water Act

Section 316(b) requires that the cooling water intake structures at electric power plants reflect the best technology available to minimize adverse environmental
impacts and is implemented through state-level NPDES permit programs. All of Generation’s power generation facilities with cooling water systems are subject
to the regulations. Facilities without closed-cycle recirculating systems (e.g., cooling towers) are potentially most affected by recent changes to the regulations.
For Generation, those facilities are Calvert Cliffs, Clinton, Dresden, Eddystone, Fairless Hills, FitzPatrick, Ginna, Gould Street, Handley, Mystic 7, Nine Mile Point
Unit 1, Peach Bottom, Quad Cities and Salem.

On October 14, 2014, the EPA's Section 316(b) rule became effective. The rule requires that a series of studies and analyses be performed to determine the
best  technology  available  to  minimize  adverse  impacts  on  aquatic  life,  followed  by  an  implementation  period  for  the  selected  technology.  The  timing  of  the
various  requirements  for  each  facility  is  related  to  the  status  of  its  current  NPDES  permit  and  the  subsequent  renewal  period.  There  is  no  fixed  compliance
schedule, as this is left to the discretion of the state permitting director.

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 rule will have on the operation of its generating facilities and its future results of operations, cash flows, and financial position.
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 potential impact of the rule has been significantly reduced since the final rule does not mandate cooling towers as a national standard
and  sets  forth  technologies  that  are  presumptively  compliant,  and  the  state  permitting  director  is  required  to  apply  a  cost-benefit  test  and  can  take  into
consideration site-specific factors, such as those that would make cooling towers infeasible.

New York Facilities

In July 2011, the New York Department of Environmental Conservation (DEC) issued a policy regarding the best available technology for cooling water intake
structures. Through its policy, the DEC established closed-cycle cooling or its equivalent as the performance goal for all existing facilities, but also provided that
the DEC will select a feasible technology whose costs are not wholly disproportionate to the environmental benefits to be gained and allows for a site-specific
determination where the entrainment performance goal cannot be achieved (i.e., the requirement

20

Table of Contents

most likely to support cooling towers). The Ginna, Nine Mile Point Unit 1, and Fitzpatrick power generation facilities have received renewals of their state water
discharge  permits  and  cooling  towers  were  not  required.  These  facilities  are  now  engaged  in  the  required  analyses  to  enable  the  environmental  agency  to
determine the best technology available in the next permit renewal cycles.

Salem

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.

Solid and Hazardous Waste

CERCLA  provides  for  immediate  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  waste  at  sites,  most  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 prior to listing on
the  NPL.  Various  states,  including  Delaware,  Illinois,  Maryland,  New  Jersey  and  Pennsylvania  and  the  District  of  Columbia  have  also  enacted  statutes  that
contain provisions substantially similar to CERCLA. In addition, RCRA governs treatment, storage and disposal of solid and hazardous wastes and cleanup of
sites where such activities were conducted.

Generation, the Utility 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 with respect to a number of sites, including MGP sites, or may undertake to investigate and remediate sites
for which they may be subject to enforcement actions by an agency or third-party.

See  Note  18 —  Commitments  and  Contingencies of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  related  to
environmental matters.

Environmental Remediation

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 2020 for compliance with environmental remediation related to contamination at former MGP sites and other gas purification sites is expected to
total $49 million which consists primarily of $45 million at ComEd. The Utility Registrants also have contingent liabilities for environmental remediation of non-
MGP  contaminants  (e.g.,  PCBs).  As  of  December  31,  2019,  the  Utility  Registrants  have  established  appropriate  contingent  liabilities  for  environmental
remediation requirements.

The Registrants’ operations have in the past, and may in the future, require substantial expenditures in order 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, Generation and the Utility Registrants may be required to make significant additional expenditures not presently determinable for other environmental
remediation costs.

Global Climate Change

Exelon has utility and generation assets, and customers, that are and will be further subject to the impacts of climate change. Accordingly, Exelon is engaged in
a  variety  of  initiatives  to  understand  and  mitigate  these  impacts,  including  investments  in  resiliency,  partnering  with  federal,  state  and  local  governments  to
minimize  impacts,  and,  importantly,  advocating  for  public  policy  that  reduces  emissions  that  cause  climate  change.  Exelon,  as  a  producer  of  electricity  from
predominantly low- and zero-carbon generating facilities (such as nuclear, hydroelectric, natural gas, wind and solar photovoltaic), has a relatively small GHG
emission profile, or carbon footprint, compared to other domestic generators of electricity (Exelon neither owns nor operates any coal-fueled generating assets).
Exelon'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 (CO2e) emitted per unit of electricity generated, is among the lowest in the industry. Other GHG emission sources at Exelon
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. Exelon facilities and operations are subject to the global
impacts  of  climate  change  and  Exelon  believes  its  operations  could  be  significantly  affected  by  the  physical  risks  of  climate  change.  See  ITEM  1A.  RISK
FACTORS for additional information.

Climate Change Regulation

Exelon is or may become subject to additional climate change regulation or legislation at the federal, regional and state levels.

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, and it became effective on November 4, 2016. Under the Paris Agreement, the Parties agreed to try to limit the global average temperature
increase  to  2°C  (3.6°F)  above  pre-industrial  levels.  In  doing  so,  Parties  developed  their  own  national  reduction  commitments.  The  United  States  submitted  a
non-binding  target  of  17%  below  2005  emission  levels  by  2020  and  26%  to  28%  below  2005  levels  by  2025.  President  Trump  has  stated  his  intention  to
withdraw the U.S. from the Paris Agreement, but no formal action has been initiated. A withdrawal would not be effective until November 2020 at the earliest.

Federal Climate Change Legislation and Regulation. It is highly unlikely that federal legislation to reduce GHG emissions will be enacted in the near-term. If such
legislation is 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.

Under the Obama Administration, the EPA finalized its Clean Power Plan regulations to reduce GHG emissions from fossil fuel-fired power plants. Subsequently,
the Trump Administration EPA proposed regulations on October 16, 2017 to repeal the CPP on the basis that the new Administration believed that the CPP rule
went beyond the EPA's authority to establish a best system of emissions reduction (BSER) for existing power plants. On August 31, 2018, EPA proposed its
Affordable Clean Energy rule to replace the CPP with revised emission guidelines based on heat rate improvement measures that could be achieved within the
fence line of existing power plants. In June 2019, EPA issued a final rule that repealed the CPP, and finalized the Affordable Clean Energy rule. The Affordable
Clean Energy rule is currently being litigated.

Given  litigation  uncertainty  around  the  final  Affordable  Clean  Energy  rule,  Exelon  and  Generation  cannot  predict  the  impacts  of  regulation  of  existing  power
plants, or individual state responses to developments related to final resolution of the Affordable Clean Energy rule, or how developments will impact their future
financial statements.

Regional and State Climate Change Legislation and Regulation. A number of states in which Exelon operates have state and regional programs to reduce GHG
emissions, including from the power sector. As the nation’s largest generator of carbon-free electricity, our fleet supports these efforts to produce safe, reliable
electricity with minimal GHGs. Notably, nine northeast and mid-Atlantic states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New
York, Rhode Island and Vermont) currently participate in the Regional Greenhouse Gas

22

Table of Contents

Initiative  (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  June  2019,  New  Jersey  was  accepted  as  a  RGGI  member  effective  January  2020.  In  October  2019,  Governor  Wolf  of  Pennsylvania  issued  an  Executive
Order that directed the Pennsylvania Department of Environmental Protection to begin a rulemaking process that will allow Pennsylvania to join the RGGI, with
the goal of reducing carbon emissions from the electricity sector.

Many  states  in  which  Exelon  subsidiaries  operate  also  have  state-specific  programs  to  address  GHGs,  including  from  power  plants.  Most  notable  of  these,
besides  RGGI,  are  through  renewable  and  other  portfolio  standards.  Additionally,  in  response  to  a  court  decision  clarifying  the  obligations  under  the  Global
Warming Solutions Act, the Massachusetts Department of Environmental Protection in 2017 finalized regulations establishing a statewide cap on CO2 emissions
from  fossil  fuel  power  plants  (Massachusetts  remains  in  RGGI  as  well).  The  effect  of  this  new  obligation  and  potential  for  market  illiquidity  in  the  early  years
represent a risk to Generation’s Massachusetts fossil facilities, including Medway and Mystic. At the same time, the District of Columbia is considering a plan to
incorporate the cost of carbon into electricity, via consumption, as well as directly into the cost of transportation and home heating fuels. Details remain to be
developed, but the specifics could have implications for Pepco’s operations.

Regardless of whether  GHG regulation occurs at the local, state, or federal level, Exelon remains one of the largest, lowest-carbon electric generators  in the
United  States,  relying  mainly  on  nuclear,  natural  gas,  hydropower,  wind,  and  solar.  The  extent  that  the  low-carbon  generating  fleet  will  continue  to  be  a
competitive advantage for Exelon depends on resolution of the CPP and Affordable Clean Energy regulations and associated current or future litigation at the
federal level, new or expanded state action on greenhouse gas emissions or direct support of clean energy technologies, including nuclear, as well as potential
market reforms that value our fleet’s emission-free attributes.

Renewable and Alternative Energy Portfolio Standards

Thirty-nine states and the District of Columbia, incorporating the vast majority of Exelon operations as well as all utility operations, have adopted some form of
RPS 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. Exelon's utilities 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.  New  York,  Illinois  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 Generation and our utilities operate are considering similar programs.

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

ITEM 1A.

RISK FACTORS

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,

Table of Contents

•

•

•

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

the impacts of on-going competition, and

emerging technologies and business models.

Regulatory and Legislative Factors primarily include changes to the laws and regulations that govern:

•

•

•

•

•

•

the design of power markets,

zero emission credit programs,

utility regulatory business model,

regulations and other standards,

environmental 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  the  effects  of  climate
change regulation could impact the GHG emissions from the Registrant’s operations,

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

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

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.

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.

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

30

Table of Contents

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  6 —  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  decommission  its  nuclear  plants.  A  decline  in  the  market  value  of  the  pension  and  OPEB  plan  assets  will  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 9 — Asset Retirement Obligations and
Note 14 — 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

31

Table of Contents

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, 2019, approximately 23%, 19%, and 18%
of the Registrants’ available credit facilities were with European, Canadian and Asian banks, respectively. See Note 16 — 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 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.

32

Table of Contents

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.

Table of Contents

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.

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, PHI’s, and ComEd’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  7 —  Property,  Plant  and  Equipment,  Note  11 —  Asset  Impairments and  Note  12  —
Intangible Assets of the Combined Notes to the Consolidated Financial Statements for additional information on long-lived asset 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

34

Table of Contents

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  a
Registrant could incur substantial costs to fulfill its obligations under these indemnities.

The Registrants have issued guarantees of the performance of third parties, which obligate the Registrant to perform in the event that the third parties do not
perform. In the event of non-performance by those third parties, a Registrant could incur substantial cost to fulfill its 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  of
amounts, if any, were already paid to the counterparties. In the spot markets, Generation is 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 and Legislative 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

35

Table of Contents

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 6 — 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 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, bad debt, 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 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 decommission fully its nuclear
units. Generation cannot predict what, if any, fee may be established in the future for SNF disposal. See Note 18 —  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.

36

Table of Contents

PECO,  BGE  and  DPL  as  operators  of  natural  gas  distribution  systems,  PECO,  BGE  and  DPL  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 which 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  and  solid  waste  disposal.  Violations  of  these  emission  and  disposal  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  contaminated  by
hazardous substances they generate. 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.

If  application  of  Section  316(b)  of  the  Clean  Water  Act,  which  establishes  a  national  requirement  for  reducing  the  adverse  impacts  to  aquatic  organisms  at
existing generating stations, requires the retrofitting of cooling water intake structures at Salem or other Exelon power plants, this development could result in
material costs of compliance. 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 13 — 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 Alternative Energy Portfolio 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  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 18 —
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.

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 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.

Exelon and ComEd have received requests for information related to government investigations. The outcome of the investigations could
have a material adverse effect on their reputation and consolidated financial statements (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 requiring
production of information concerning their lobbying activities in the state

38

Table of Contents

of Illinois. On October 4, 2019, Exelon and ComEd received a second grand jury subpoena from the U.S. Attorney’s Office for the Northern District of Illinois
requiring production of records of any communications with certain individuals and entities. On October 22, 2019, the SEC notified Exelon and ComEd that it has
also opened an investigation into their lobbying activities. Exelon and ComEd have cooperated fully, including by providing additional information requested by
the U.S. Attorney’s Office and the SEC, and intend to continue to cooperate fully and expeditiously with the U.S. Attorney’s Office and the SEC. The outcome of
the  U.S.  Attorney’s  Office  and  SEC  investigations  cannot  be  predicted  and  could  subject  Exelon  and  ComEd  to  criminal  or  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 reputation or relationship with regulatory and legislative authorities, customers and other stakeholders, as well as their consolidated
financial statements. 

Operational Factors

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

Physical plants could be placed at greater risk of damage should changes in the global climate produce unusual variations in temperature and weather patterns,
resulting in more intense, frequent and extreme weather events, unprecedented levels of precipitation and a change in sea level. The Registrants’ 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.  Still disruption or failure of  electric generation,  transmission  or distribution
systems or natural gas production, transmission, storage or distribution systems in the event of a hurricane, tornado or other severe weather event, or otherwise,
could prevent the Registrants from operating their business in the normal course.

The Registrants are considering ways to address the effect of GHG emissions on climate change. If carbon reduction regulation or legislation becomes effective,
the Registrants could incur costs either to limit further the GHG emissions from their operations or to procure emission allowance credits for Generation’s fossil
fuel-fired generation. See ITEM 1. BUSINESS — Global Climate Change.

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 performance at

39

Table of Contents

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  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 $13.9 billion limit for a single incident.

See Note 18 — 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 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 NDTs 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 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 9 — 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  advanced  metering
infrastructure, 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,  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.

41

Table of Contents

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 1. BUSINESS
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  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.

42

Table of Contents

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.

(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. 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 reflect a summer rating. Wind and solar facilities reflect name plate capacity.
(e) Net generation capacity is stated at proportionate ownership share.
(f) Reflects Generation’s  interest in CENG, a joint venture with EDF. See  ITEM 1. —  BUSINESS —  Exelon Generation  Company, LLC — Nuclear Facilities for additional

information.

(g) Reflects  the  prior  sale  of  49%  of  EGRP  to  a  third  party.  See  Note  22 —  Variable  Interest  Entities of  the  Combined  Notes  to  Consolidated  Financial  Statements  for

additional information.

(h) 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.

(i) Generation directly owns a 50% interest in the Albany Green Energy station and an additional 49% through the consolidation of a Variable Interest Entity.
(j) Generation has plans to retire and cease generation operations at certain plants in 2020 and 2021.
(k) Generation has deactivated the site and is evaluating for potential return of service or retirement in 2020.

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

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. During the first quarter of 2019, due to a change in economics in our New England region, Generation
changed the way that information is reviewed by the CODM. The New England region is no longer regularly reviewed as a separate region by the CODM nor
presented separately in any external information presented to third parties. Information for the New England region is reviewed by the CODM as part of Other
Power Regions. 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, 2019 compared to the year ended December 31, 2018,
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, 2018 compared to the year ended  December 31,
2017, refer to ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS in the 2018-Form 10-
K, which was filed with the SEC on February 8, 2019.

Year Ended December 31, 2019 Compared  to  Year  Ended  December 31, 2018. Net  income  attributable  to  common  shareholders  increased by $931
million and diluted earnings per average common share increased to $3.01 in 2019 from $2.07 in 2018 primarily due to:

•

•

•

•

•

•

•

•

•

•

Higher net unrealized and realized gains on NDT funds;

Decreased accelerated depreciation and amortization due to the early retirement of the Oyster Creek nuclear facility in September 2018 and TMI in
September 2019 and the absence of a charge associated with the remeasurement of the Oyster Creek ARO in 2018;

Decreased Operating and maintenance expense at Generation which includes the impacts of previous cost management programs, lower pension
and OPEB costs and increased NEIL insurance distributions;

A benefit associated with the remeasurement of the TMI ARO in the first quarter of 2019 and the annual nuclear ARO update in the third quarter of
2019;

Decreased nuclear outage days;

Lower mark-to-market losses;

Regulatory rate increases at PECO, BGE, Pepco, DPL, and ACE;

Increased electric distribution, energy efficiency and transmission earnings at ComEd;

Decreased storms costs at PECO and BGE; and

Research and development income tax benefits.

The increases were partially offset by;

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 2019 and 2018 ranged from 26.0 percent to 29.0
percent. 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 47.3 percent and 46.2 percent for the years ended December 31, 2019 and 2018, respectively.

Significant 2019 Transactions and Developments

Utility Rates and Base Rate Proceedings

The Utility Registrants file base 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 position.

The following tables show the Utility Registrants’ completed and pending distribution base rate case proceedings in 2019. See Note 3 — Regulatory Matters of

PECO Transmission Formula Rate

On May 1, 2017, PECO filed a request with FERC seeking approval to update its transmission rates and change the manner in which PECO’s transmission rate
is  determined  from  a  fixed  rate  to  a  formula  rate.  The  formula  rate  will  be  updated  annually  to  ensure  that  under  this  rate  customers  pay  the  actual  costs  of
providing  transmission  services.  PECO’s  initial  formula  rate  filing  included  a  requested  increase  of    $22  million to  PECO’s  annual  transmission  revenue
requirement,  which  reflected  a  ROE  of    11%,  inclusive  of  a  50  basis  point  adder  for  being  a  member  of  a  RTO.  On  June  27,  2017,  FERC  issued  an  Order
accepting  the  filing  and  suspending  the  proposed  rates  until  December  1,  2017,  subject  to  refund,  and  set  the  matter  for  hearing  and  settlement  judge
procedures.

On  December  5,  2019,  FERC  issued  an  Order  accepting  without  modification  the  settlement  agreement  filed  by  PECO  and  other  parties  in  July  2019.  The
settlement results in an increase of approximately $14 million with a return on rate base of 7.62% compared to PECO's initial formula rate filing and allows for an
ROE of 10.35%, inclusive of a 50 basis point adder for being a member of the RTO. The settlement did not have a material impact on PECO's 2017, 2018, or
2019  annual  transmission  revenue  requirements.  PECO  will  update  its  rates  in  2020  and  refund  estimated  overcollections  totaling  approximately  $28  million
related to the amounts billed under the proposed rates in effect since 2017.

Pursuant  to  the  transmission  formula  rate  request  discussed  above,  PECO  made  its  annual  formula  rate  updates  in  May  2018  and  2019,  which  included  a
decrease of $6 million and an increase of $8 million, respectively, to the annual transmission revenue requirement. The updated transmission formula rates were
effective on June 1, 2018 and 2019, respectively, subject to refund.

Cost Management Programs

Exelon continues to be committed to managing its costs. On October 31, 2019, Exelon announced additional annual cost savings of approximately $100 million,
at Generation, to be achieved by 2022. These actions are in response to the continuing economic challenges confronting Generation’s business, necessitating
continued focus on cost management through enhanced efficiency and productivity.

FERC Order on the PJM MOPR

On December 19, 2019, FERC issued an order directing PJM to extend the MOPR to include new and existing resources, including nuclear, that receive state
subsidies, effective as of PJM’s next capacity auction. Unless Illinois and New Jersey can implement an FRR program in their PJM zones, the MOPR will apply
to Generation's nuclear plants in those states receiving ZEC benefits, resulting in higher offers for those units that may not clear the capacity market. On January
21, 2020, Exelon, PJM and a number of other entities submitted individual requests for rehearing. Exelon is currently working with PJM and other stakeholders
to pursue the FRR option but cannot predict whether the legislative and regulatory changes can be implemented  prior to the next capacity auction in PJM. If
Generation’s state-supported nuclear plants in PJM or NYISO are subjected to the MOPR without compensation under an FRR or similar program, it could have
a material adverse impact on Exelon's and Generation's financial

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

Early Plant Retirements

Oyster Creek. Generation permanently ceased generation operations at Oyster Creek on September 17, 2018. On July 31, 2018, Generation entered into an
agreement with Holtec International and its wholly owned subsidiary, Oyster Creek Environmental Protection, LLC, for the sale and decommissioning of Oyster
Creek.  The  sale  was  completed  on  July  1,  2019.  Exelon  and  Generation  recognized  a  loss  on  the  sale  in  the  third  quarter  2019,  which  was  immaterial.  See
Note 2 — Mergers, Acquisitions and Dispositions of the Combined Notes to Consolidated Financial Statements for additional information.

Three  Mile  Island. Generation  permanently  ceased  operations  at  TMI  on  September  20,  2019.  As  a  result  of  the  decision  to  early  retire  TMI,  Exelon  and
Generation recorded a $176 million incremental pre-tax net charge for the year ended December 31, 2019 primarily due to accelerated depreciation of the plant
assets, partially offset by a benefit associated with the remeasurement of the TMI ARO in the first quarter of 2019.

Salem. In 2017, PSEG announced that its New Jersey nuclear plants, including Salem, of which Generation owns a  42.59% ownership interest, were showing
increased  signs  of  economic  distress,  which  could  lead  to  an  early  retirement.  PSEG  is the  operator  of  Salem  and  also  has  the  decision-making  authority  to
retire Salem. In 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. On April 18, 2019, the NJBPU approved the award of ZECs to Salem Unit 1 and Salem Unit 2. Assuming the continued effectiveness
of the New Jersey ZEC program, Generation no longer considers Salem to be at heightened risk for early retirement.

Dresden, Byron and Braidwood. Generation’s Dresden, Byron and Braidwood nuclear plants in Illinois are also showing increased signs of economic distress,
which could lead to an early retirement, 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.  Exelon  continues  to  work  with
stakeholders on state policy solutions, while also advocating for broader market reforms at the regional and federal level.

See Note 3 —  Regulatory Matters, Note 6 —  Early Plant Retirements and  Note  9 —  Asset Retirement Obligations of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information.

CENG Put Option

On November 20, 2019, Generation received notice of EDF’s intention to exercise the put option and sell its 49.99% equity 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, the purchase price is
to be determined by agreement of the parties, or absent such agreement, by a third-party arbitration process. Any resulting sale would be subject to the approval
of  the  NYPSC,  the  FERC  and  the  NRC.  The  process  and  regulatory  approvals  could  take  one  to  two  years  or  more  to  complete.  See  Note  2 -  Mergers,
Acquisitions and Dispositions for additional information.

Conowingo Hydroelectric Project

In  connection  with  Generation’s  pursuit  of  a  new  FERC  license  for  Conowingo,  on  October  29,  2019,  Generation  and  MDE  filed  with  FERC  a  Joint  Offer  of
Settlement that would resolve all outstanding issues between the parties, effective upon and subject to FERC’s approval and incorporation of the terms into the
new license when issued. The financial impact of this settlement, along with other anticipated and prior license commitments, would be recognized over the term
of the new 50-year license and is estimated to be, on average, $11 million to $14 million per year, including capital and operating costs. The actual timing and
amount  of a 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. See Note 3 —  Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional
information.

Pacific Gas & Electric Bankruptcy

67

Table of Contents

Generation’s  Antelope  Valley,  a  242  MW  solar  facility  in  Lancaster,  CA,  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. As of December 31, 2019, Generation had approximately $725 million and $485 million of net long-
lived assets and nonrecourse debt outstanding,  respectively, related to Antelope Valley. PG&E’s bankruptcy  created an event of default for Antelope Valley’s
nonrecourse  debt  that  provides  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 ongoing event of default and 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  and  continues  to  be  classified  as  current  as  of  December 31,
2019.

In the first quarter of 2019, Generation assessed and determined that Antelope Valley’s long-lived assets were not impaired. Significant changes in assumptions
such as  the  likelihood of  the  PPA being  rejected  as part  of the  bankruptcy  proceedings  could potentially  result  in future  impairments  of Antelope  Valley's net
long-lived  assets,  which  could  be  material.  Generation  is  monitoring  the  bankruptcy  proceedings  for  any  changes  in  circumstances  that  would  indicate  the
carrying amount of the net long-lived assets of Antelope Valley may not be recoverable.

See Note 11 —  Asset Impairments and Note  16 —  Debt and Credit Agreements of the Combined Notes to Consolidated Financial Statements for additional
information on the PG&E bankruptcy.

Exelon’s Strategy and Outlook for 2020 and Beyond

Exelon’s  value  proposition  and  competitive  advantage  come  from  its  scope  and  its  core  strengths  of  operational  excellence  and  financial  discipline.  Exelon
leverages its integrated business model to create value. Exelon’s regulated and competitive businesses feature a mix of attributes that, when combined, offer
shareholders and customers a unique value proposition:

•

•

The Utility Registrants provide a foundation for steadily growing earnings, which translates to a stable currency in our stock.

Generation’s competitive businesses provide free cash flow to invest primarily in the utilities and to reduce debt.

Exelon believes its strategy provides a platform for optimal success in an energy industry experiencing fundamental and sweeping change.

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 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 generation to load matching to reduce earnings volatility. 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.

Exelon’s financial priorities are to maintain investment grade credit metrics at each of the Registrants, to maintain optimal capital structure and to return value to
Exelon’s shareholders with an attractive dividend throughout the energy commodity market cycle and through stable earnings growth.

68

Table of Contents

As  part  of  its  strategic  business  planning  process,  Exelon  routinely  reviews  its  hedging  policy,  dividend  policy,  operating  and  capital  costs,  capital  spending
plans, strength of its balance sheet and credit metrics, and sufficiency of its liquidity position, by performing various stress tests with differing variables, such as
commodity price movements, increases in margin-related transactions, changes in hedging practices, and the impacts of hypothetical credit downgrades.

Exelon’s Board of Directors approved a dividend policy providing a raise of 5% each year for the period covering 2018 through 2020, beginning with the March
2018 dividend.

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.

Exelon  continues  to  be  committed  to  managing  its  costs.  In  November  2017,  Exelon  announced  a  commitment  for  $250 million of  cost  savings,  primarily  at
Generation, to be achieved by 2020. In November 2018, Exelon announced the elimination of an approximately additional $200 million of annual ongoing costs,
through  initiatives  primarily at  Generation  and  BSC,  by  2021.  Approximately  $150 million is expected  to  be  related  to  Generation,  with the  remaining  amount
related to the Utility Registrants. In October 2019, Exelon announced additional annual cost savings of approximately $100 million, at Generation, to be achieved
by  2022.  These  actions  are  in  response  to  the  continuing  economic  challenges  confronting  Generation's  business,  necessitating  continued  focus  on  cost
management through enhanced efficiency and productivity.

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  $26  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 $13 billion by the end of 2023. 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.

See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information on the Smart Meter and Smart Grid
Investments and infrastructure development and enhancement programs.

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 long-term growth strategy is to ensure appropriate valuation of its generation
assets,  in  part  through  public  policy  efforts,  identify  and  capitalize  on  opportunities  that  provide  generation  to  load  matching  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 over the last several years; in part reflecting an increase in supply due to strong natural gas production (due to shale gas development).

FERC Inquiry on Resiliency

On August 23, 2017, the DOE staff released its report on the reliability of the electric grid. One aspect of the wide-ranging report is the DOE’s recognition that
the electricity markets do not currently value the resiliency provided by base-load generation, such as nuclear plants. On September 28, 2017, the DOE issued a
Notice  of  Proposed  Rulemaking  (NOPR)  that  would  entitle  certain  eligible  resilient  generating  units  (i.e.,  those  located  in  organized  markets,  with  a  90-day
supply of fuel on site, not already subject to state cost of service regulation and satisfying certain other requirements) to recover fully allocated costs and earn a
fair return on equity on their investment. On January 8, 2018, FERC issued an order terminating the rulemaking docket that it initiated to address the proposed
rule  in  the  DOE  NOPR,  concluding  the  proposed  rule  did  not  sufficiently  demonstrate  there  is  a  resiliency  issue  and  that  it  proposed  a  remedy  that  did  not
appear to be just, reasonable and nondiscriminatory as required under the Federal Power Act. At the same time, FERC initiated a new proceeding to consider
resiliency challenges to the bulk power system and evaluate whether additional FERC action to address resiliency would be appropriate. FERC directed each
RTO  and  ISO  to  respond  within  60  days  to  24  specific  questions  about  how  they  assess  and  mitigate  threats  to  resiliency.  Thereafter,  interested  parties
submitted reply comments on May 9, 2018, and a few parties submitted further replies. Exelon has been and will continue to be an active participant in these
proceedings but cannot predict the final outcome or its potential financial impact, if any, on Exelon or Generation.

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, as amended, (the Act) from imports of uranium products, alleging that
these imports threaten national security (the Petition). The relief requested would have required U.S. nuclear reactors to purchase at least 25% of their uranium
needs from domestic mines for the next 10 years or more. The Act was promulgated by Congress to protect essential national security industries whose survival
is threatened by imports. As such, the Act authorizes the Secretary of Commerce (the Secretary) to conduct investigations to evaluate the effects of imports of
any  item  on  the  national  security  of  the  U.S.  The  Petition  alleges  that  the  loss  of  a  viable  U.S.  uranium  mining  industry  would  have  a  significant  detrimental
impact on the national, energy, and economic security of the U.S. and the ability of the country to sustain an independent nuclear fuel cycle.

On July 18, 2018, the Secretary announced that the DOC had initiated an investigation in response to the petition. The Secretary submitted a report to President
Trump  on  April  14,  2019  that  has  not  been  made  public.  On  July  12,  2019,  the  President  issued  a  memorandum  indicating  that  he  did  not  agree  with  the
Secretary's  finding  that  uranium  imports  threaten  to  impair  the  national  security  of  the  United  States,  choosing  not  to  impose  any  trade  restrictions  at  this
time.The President found that a fuller analysis of national security considerations with respect to the entire nuclear fuel supply chain is necessary and directed
that a United States Nuclear Fuel Working Group (Working Group) be established to develop recommendations for reviving and expanding domestic nuclear fuel
production. The Working Group report has not yet been issued and is not expected to be made public. The Working Group is co-chaired by the Assistant to the
President for National Security Affairs and the Assistant to the President for Economic Policy. Exelon will monitor and volunteer to provide information to support
the Working Group's efforts. Exelon and Generation cannot currently predict the outcome of the Working Group report and subsequent actions.

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

70

Table of Contents

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

Modest economic growth partially offset by energy efficiency initiatives is resulting in relatively flat load growth in electricity for the Utility Registrants. ComEd,
PECO, BGE, Pepco, DPL and ACE are projecting load volumes to increase (decrease) by (0.3)%, (0.7)%, (1.2)%, (0.4)%, (0.5)% and (0.4)%, respectively, in
2020 compared to 2019.

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, 2019,  the  percentage  of  expected  generation  hedged  for  the  Mid-Atlantic,
Midwest, New York and ERCOT reportable segments is 91%-94% and 61%-64% for 2020 and 2021, respectively. Generation has been and will continue to be
proactive in using hedging strategies to mitigate commodity price risk.

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  2020 through  2024 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 results of operations, cash flows and financial positions.

See  Note  15 —  Derivative  Financial  Instruments of  the  Combined  Notes  to  Consolidated  Financial  Statements  and 
QUALITATIVE DISCLOSURES ABOUT MARKET RISK for additional information.

ITEM  7A.  QUANTITATIVE  AND

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

Environmental Legislative and Regulatory Developments

Exelon was actively involved in the Obama Administration’s development and implementation of environmental regulations for the electric industry, in pursuit of
its  business  strategy  to  provide  reliable,  clean,  affordable  and  innovative  energy  products.  These  efforts  have  most  frequently  involved  air,  water  and  waste
controls for fossil-fueled electric generating units, as set forth in the discussion below. These regulations have had a disproportionate adverse impact on coal-
fired power plants, requiring significant expenditures of capital and variable operating and maintenance expense, and have resulted in the retirement of older,
marginal facilities. Due to its low emission generation portfolio, Generation has not been significantly affected by these regulations, representing a competitive
advantage relative to electric generators that are more reliant on fossil fuel plants.

Through the issuance of a series of Executive Orders (EO), President Trump has initiated review of a number of EPA and other regulations issued during the
Obama  Administration,  with  the  expectation  that  the  Administration  will  seek  repeal  or  significant  revision  of  these  rules.  Under  these  EOs,  each  executive
agency is required to evaluate existing regulations and make recommendations regarding repeal, replacement, or modification. The

71

Table of Contents

Administration’s actions are intended to result in less stringent compliance requirements under air, water, and waste regulations. The exact nature, extent, and
timing of the regulatory changes are unknown, as well as the ultimate impact on Exelon’s and its subsidiaries results of operations and cash flows.

In particular, the Administration has targeted existing EPA regulations for repeal, including notably the Clean Power Plan, as well as revoking many Executive
Orders, reports, and guidance issued by the Obama Administration on the topic of climate change or the regulation of greenhouse gases. The Executive Order
also  disbanded  the  Interagency  Working  Group  that  developed  the  social  cost  of  carbon  used  in  rulemakings,  and  withdrew  all  technical  support  documents
supporting the calculation. Other regulations that have been specifically identified for review are the Clean Water Act rule relating to jurisdictional waters of the
U.S., the Steam Electric Effluent Guidelines relating to waste water discharges from coal-fired power plants, and the 2015 National Ambient Air Quality Standard
(NAAQS) for ozone. The review of final rules could extend over several years as formal notice and comment rulemaking process proceeds.

Air Quality

Mercury and Air Toxics Standard Rule (MATS). On December 16, 2011, the EPA signed a final rule to reduce emissions of toxic air pollutants from power
plants and signed revisions to the NSPS for electric generating units. The final rule, known as MATS, requires coal-fired electric generation 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.  Numerous  entities  challenged  MATS  in  the  D.C.  Circuit  Court,  and  Exelon  intervened  in  support  of  the  rule.  In  April  2014,  the  D.C.  Circuit  Court
issued  an  opinion  upholding  MATS  in  its  entirety.  On  appeal,  the  U.S.  Supreme  Court  decided  in  June  2015  that  the  EPA  unreasonably  refused  to  consider
costs in determining whether it is appropriate and necessary to regulate hazardous air pollutants emitted by electric utilities, but did not vacate the rule. On April
27, 2017, the D.C. Circuit Court granted EPA’s motion to hold the litigation in abeyance, pending EPA’s review of the MATS rule pursuant to President Trump’s
EO discussed above. Notwithstanding the Court’s order to hold the litigation in abeyance, the MATS rule remains in effect. Exelon will continue to participate in
the  remanded  proceedings  before  the  D.C.  Circuit  Court  as  an  intervenor  in  support  of  the  rule.  On  December  28,  2018,  the  EPA  proposed  to  revoke  the
"appropriate and necessary" finding underpinning the MATS rule. While the proposal would leave in place the rule, it would leave it vulnerable to future legal
challenge.  On  February  7,  2019,  EPA  published  its  Reconsideration  of  Supplemental  Finding  and  Residual  Risk  and  Technology  Review.  After  considering
public comment, EPA transmitted a final version to the Office of Management and Budget for review prior to publication.

Clean Power Plan. On April 28, 2017, the D.C. Circuit Court issued orders in separate litigation related to the EPA’s actions under the Clean Power Plan (CPP)
to  amend  Clean  Air  Act  Section  111(d)  regulation  of  existing  fossil-fired  electric  generating  units  and  Section  111(b)  regulation  of  new  fossil-fired  electric
generating units. In both cases, the Court has determined to hold the litigation in abeyance pending a determination whether the rule should be remanded to the
EPA.  In  June  2019,  EPA  issued  a  final  rule  that  repealed  the  CPP,  and  finalized  the  Affordable  Clean  Energy  rule  to  replace  the  CPP  with  less  stringent
emissions  guidelines  based  on  heat  rate  improvement  measures  that  could  be  achieved  within  the  fence  line  of  existing  power  plants.  The  Affordable  Clean
Energy rule is currently being litigated.

2015 Ozone National Ambient Air Quality Standards (NAAQS). On April 11, 2017, the D.C. Circuit Court ordered that the consolidated 2015 ozone NAAQS
litigation be held in abeyance pending EPA’s further review of the 2015 Rule. On August 23, 2019, the D.C. Circuit Court upheld the stringency of NAAQS, but
remanded certain aspects of its secondary standard to EPA for revision.

Primary SO2 National Ambient Air Quality Standards (NAAQS). EPA took final action on April 17, 2019 to retain the current primary SO2 standard without
revision, leaving the standard established in 2010 in effect.

Climate  Change. Exelon  supports  comprehensive  climate  change  legislation  or  regulation,  including  a  cap-and-trade  program  for  GHG  emissions,  which
balances  the  need  to  protect  consumers,  business  and  the  economy  with  the  urgent  need  to  reduce  national  GHG  emissions.  In  the  absence  of  Federal
legislation, the EPA is moving forward with the regulation of GHG emissions under the Clean Air Act. In addition, there have been recent developments in the
international regulation of GHG emissions pursuant to the United Nations Framework Convention on Climate Change (“UNFCCC” or “Convention”). See ITEM 1.
BUSINESS, "Global Climate Change" for additional information.

Table of Contents

Water Quality

Section 316(b) requires that the cooling water intake structures at electric power plants reflect the best technology available to minimize adverse environmental
impacts and is implemented through state-level NPDES permit programs. All of Generation’s power generation facilities with cooling water systems are subject
to the regulations. Facilities without closed-cycle recirculating systems (e.g., cooling towers) are potentially most affected by recent changes to the regulations.
For Generation, those facilities are Calvert Cliffs, Clinton, Dresden, Eddystone, Fairless Hills, FitzPatrick, Ginna, Gould Street, Handley, Mystic 7, Nine Mile Point
Unit 1, Peach Bottom, Quad Cities, and Salem. See ITEM 1. BUSINESS, "Water Quality" for additional information.

Clean Water Rule

In 2015,  the  EPA and  the  US Army Corps of Engineers,  finalized the  Clean Water Rule that  significantly expanded  the definition  of  the  Waters of the  United
States under the Clean Water Act and resulted in increased environmental costs for some projects. On October 22, 2019, the EPA and the US Army Corps of
Engineers repealed the 2015 Clean Water Rule and restored the definition of the Waters of the United States that existed prior to this rule. On January 23, 2020,
a new final rule was issued by the EPA and the US Army Corps of Engineers to streamline and clarify the definition of Waters of the United States and will be
effective sixty days after publication in the Federal Register. This rule represents final action by these government agencies to narrow the scope of Waters of the
United States that are regulated under the federal Clean Water Act.

Solid and Hazardous Waste

In October 2015, the first federal regulation for the disposal of coal combustion residuals (CCR) from power plants became effective. The rule classifies CCR as
non-hazardous waste under RCRA. Under the regulation, CCR will continue to be regulated by most states subject to coordination with the federal regulations.
Generation has previously recorded accruals consistent with state regulation for its owned coal ash sites, and as such, the regulation is not expected to impact
Exelon’s and Generation’s financial results. Generation does not have sufficient information to reasonably assess the potential likelihood or magnitude of any
remediation requirements that may be asserted under the new federal regulations for coal ash disposal sites formerly owned by Generation. For these reasons,
Generation is unable to predict whether and to what extent it may ultimately be held responsible for remediation and other costs relating to formerly owned coal
ash disposal sites under the new regulations.

See  Note  18 —  Commitments  and  Contingencies of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  related  to
environmental matters.

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 fixed resource requirement 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,  including  renewable  resource  developers,  environmental  advocates,  and
coal-fueled  generators.  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

73

Table of Contents

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 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  $10.5  billion at  December  31,  2019.  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

74

Table of Contents

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 nuclear decommissioning trust 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 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. The successful operation of nuclear plants in the U.S. beyond the initial 40-year license terms has
prompted the NRC to consider regulatory and technical requirements for potential plant operations for an 80-year nuclear operating term. 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 2030. 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 that DOE will
begin accepting SNF, see Note 18 — 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 $10.5 billion to approximately $13.2 billion.

The following table illustrates the significant impact that changes in the CARFR, when combined with changes in projected amounts and expected timing of cash
flows, can have on the valuation of the ARO (dollars in millions):

Goodwill (Exelon, ComEd and PHI)

As  of  December  31,  2019,  Exelon’s  $6.7 billion carrying  amount  of  goodwill  consists  of  $2.6 billion at  ComEd,  $4 billion at  PHI  and  immaterial  amounts  at
Generation and DPL. 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 tested 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 12 — 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  test 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.  In  applying  the  second  step,  if needed,  management  must
estimate the fair value of specific assets and liabilities of the reporting unit.

While  the  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.
Based on the results of the

76

 
 
Table of Contents

last annual quantitative goodwill tests performed as of November 1, 2016 and November 1, 2018 for ComEd and PHI, respectively, the estimated fair values of
the ComEd, Pepco, DPL and ACE reporting units would have needed to decrease by more than 30%, 30%, 20% and 30%, respectively, for ComEd and PHI to
fail the first step of their respective impairment tests.

See Note 1 —  Significant Accounting Policies and  Note  12 —  Intangible Assets of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional
information.

Purchase Accounting (Exelon, Generation and PHI)

Assets acquired and liabilities assumed in an acquired business are recorded at their estimated fair values on the date of acquisition. The difference between the
purchase price amount and the net fair value of assets acquired and liabilities assumed is recognized as goodwill on the balance sheet if the purchase price
exceeds  the  estimated  net  fair  value  or  as  a  bargain  purchase  gain  on  the  income  statement  if  the  purchase  price  is  less  than  the  estimated  net  fair
value. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment, often utilizes independent valuation experts and
involves  the  use  of  significant  estimates  and  assumptions  with respect  to the  timing and  amounts  of  future  cash  inflows and  outflows,  discount  rates,  market
prices and asset lives, among other items. The judgments made in the determination of the estimated fair value assigned to the assets acquired and liabilities
assumed, as well as the estimated useful life of each asset and the duration of each liability, could significantly impact the financial statements in periods after
acquisition, such as through depreciation and amortization expense. The allocation of the purchase price may be modified up to one year after the acquisition
date as more information is obtained about the fair value of assets acquired and liabilities assumed. If the transaction is determined to be an asset acquisition
the purchase price is allocated to the assets acquired and the liabilities assumed and no goodwill or bargain purchase gain would be recorded.  See Note 2 —
Mergers, Acquisitions and Dispositions 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 has 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,  Note  2 —  Mergers,  Acquisitions  and  Dispositions and  Note  12 —  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 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

77

Table of Contents

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  and there will usually be differences between prospective financial information and
actual results, and those differences 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 11 — 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 includes 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.

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. See Note  6 —  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 other postretirement employee benefit 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 applied to benefit obligations, the long-term expected rate of return on plan
assets,  the  anticipated  rate  of  increase  of  health  care  costs,  Exelon’s  expected  level  of  contributions  to  the  plans,  the  incidence  of  participant  mortality,  the
expected remaining service period of plan participants, the level of compensation and rate of compensation increases, employee age, length of service, 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. Exelon amortizes actuarial gains or losses in excess of a corridor of 10% of the greater of the projected benefit obligation
or the market-related value (MRV) of plan assets over the expected average remaining service period of plan participants.

Pension and other postretirement benefit 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 other postretirement benefit 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 other postretirement benefit plan assets and certain pension plan assets, Exelon uses fair value to calculate
the MRV.

Discount  Rate.  At December  31,  2019 and  2018,  the  discount  rates  were  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  other  postretirement
benefit  obligations.  The  spot  rates  are  used  to  discount  the  estimated  future  benefit  distribution  amounts  under  the  pension  and  other  postretirement  benefit
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  is  supported  by  an  actuarial  experience
study of Exelon's plan participants and beginning in 2019, utilizes the Society of Actuaries' 2019 base table (Pri-2012) and MP-2019 improvement scale adjusted
to a 0.75% long-term rate reached in 2035.

In general, the discount rate will have a larger impact on the pension and other postretirement benefit 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 14 —  Retirement Benefits of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  regarding  the  accounting  for  the
defined benefit pension plans and other postretirement benefit 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 would be recognized in the Consolidated Statements of Operations and Comprehensive Income and
could be material.

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 other postretirement benefit plans that are recorded as regulatory assets in

regulatory liability of  $(44) million (before  taxes)  related  to PECO’s  portion  of the  deferred  costs  associated  with  Exelon’s  other postretirement  benefit  plans that  would
result in an increase in OCI if reversed.

Table of Contents

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  settlement  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  15 —  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 to 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.

Normal Purchases and Normal Sales Exception. 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.

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

81

Table of Contents

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 17 — Fair Value of Financial Assets and Liabilities and
Note 15 — 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 13 — 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

82

Table of Contents

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  18 —  Commitments  and
Contingencies of the Combined Notes to Consolidated Financial Statements for additional information.

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 Alternative Revenue Program (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 independent
system operators.

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

83

Table of Contents

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 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, 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.  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 Uncollectible Accounts (Utility Registrants)

Utility Registrants estimate the allowance for uncollectible accounts on customer receivables by applying loss rates developed specifically for each company to
the  outstanding  receivable  balance  by  customer  risk  segment.  Risk  segments  represent  a  group  of  customers  with  similar  credit  quality  indicators  that  are
comprised based on various attributes, including delinquency of their balances and payment history. 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  uncollectible  accounts  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.

Results of Operations by Registrant

The Registrants' Results of Operations includes discussion of RNF, which is a financial measure not 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. 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 measure because it
provides information that can be used to evaluate its operational performance. For the Utility Registrants, their Operating revenues reflect the full and current
recovery of commodity procurement costs given the rider mechanisms approved by their respective state regulators. The commodity procurement costs, which
are recorded in Purchased power and fuel expense, and the associated revenues can be volatile. Therefore, the Utility Registrants believe that RNF is a useful
measure because it excludes the effect on Operating revenues caused by the volatility in these expenses.

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018. Net income attributable to membership interest increased by $755 million
primarily due to:

•

•

•

•

•

•

•

Higher net unrealized and realized gains on NDT funds;

Decreased accelerated depreciation and amortization due to the early retirement of the Oyster Creek nuclear facility in September 2018 and TMI in
September 2019 and the absence of a charge associated with the remeasurement of the Oyster Creek ARO;

Decreased  operating  and  maintenance  expense  at  Generation  which  includes  the  impacts  of  previous  cost  management  programs  and  lower
pension and OPEB costs, and increased NEIL insurance distributions;

A benefit associated with the remeasurement of the TMI ARO in the first quarter of 2019 and the annual nuclear ARO update in the third quarter of
2019;

Decreased nuclear outage days;

Lower mark-to-market losses;

Research and development income tax credits.

Lower capacity prices.

Generation

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.
During  the  first  quarter  of  2019,  due  to  a  change  in  economics  in  our  New  England  region,  Generation  changed  the  way  that  information  is  reviewed  by  the
CODM.  The  New  England  region  will  no  longer  be  regularly  reviewed  as  a  separate  region  by  the  CODM  nor  will  it  be  presented  separately  in  any  external
information presented to third parties. Information for the New England region will be reviewed by the CODM as part of 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 and ancillary services. Fuel expense includes the fuel costs for owned generation and fuel costs associated with tolling agreements.

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 as
the ratio of the actual output  of a plant over a period of time to its output if the plant had operated at full average annual mean capacity for that time period.
Generation considers capacity factor to be a useful measure to analyze the nuclear fleet performance between periods. Generation has included the analysis
below as a complement to the financial information provided in accordance with GAAP. However, these measures are not a presentation defined under GAAP
and may not be comparable to other companies’ presentations or be more useful than the GAAP information provided elsewhere in this report.

Effective income tax rates were 26.9% and (29.5)% for the years ended December 31, 2019 and 2018, respectively. The change in 2019 is primarily related to
research  and  development  claims,  renewable  tax  credits  and  one-time  adjustments.  See  Note  13 —  Income Taxes of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information.

Equity in losses of unconsolidated affiliates for the twelve months ended December 31, 2019 compared to the same period in 2018 decreased primarily due
to the impairment of equity method investments in certain distributed energy companies.

Net  income  attributable  to  noncontrolling  interests for  the  twelve  months  ended  December  31,  2019 compared  to  the  same  period  in  2018 decreased
primarily due to the offsetting noncontrolling interest impact of the impairment of equity method investments in certain distributed energy companies.

Year  Ended  December  31,  2019 Compared  to  Year  Ended  December  31,  2018.  Net  income  increased  by  $24  million primarily  due  to  higher  electric
distribution,  transmission  and  energy  efficiency  formula  rate  earnings  (reflecting  the  impacts  of  higher  rate  base,  partially  offset  by  lower  allowed  electric
distribution ROE due to a decrease in treasury rates).

Revenues  Net  of  Purchased  Power  Expense.  There  are  certain  drivers  of  Operating  revenues  that  are  fully  offset  by  their  impact  on  Purchased  power
expense,  such  as  commodity,  REC  and  ZEC  procurement  costs  and  participation  in  customer  choice  programs.  ComEd  recovers  electricity,  REC  and  ZEC
procurement costs from customers without mark-up. Therefore, fluctuations in these costs have no impact on RNF.

Customers  have  the  choice  to  purchase  electricity  from  a  competitive  electric  generation  supplier.  Customer  choice  programs  do  not  impact  the  volume  of
deliveries, but do impact Operating revenues related to supplied electricity.

Revenue Decoupling. The  demand  for  electricity  is  affected  by  weather  and  customer  usage.  Operating  revenues  are  not  impacted  by  abnormal  weather,
usage per customer or number of customers as a result of a change to the electric distribution formula rate pursuant to FEJA.

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, 2019, as compared to the same period in 2018, electric distribution revenue increased primarily due to the impact of higher rate base and
increased depreciation expenses, offset by lower allowed ROE due to a decrease in treasury rates. See Operating and Maintenance Expense below and 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, 2019, as compared to
the  same  period  in  2018,  transmission  revenue  increased  primarily  due  to  the  impact  of  increased  peak  load,  higher  rate  base,  and  higher  fully  recoverable
costs.  See  Operating  and  Maintenance  Expense  below  and  Note  3 —  Regulatory Matters of  the  Combined  Notes  to  Consolidated  Financial  Statements  for
additional information.

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, 2019, as compared to the same period in 2018, primarily due to the impact of higher rate base and increased regulatory asset amortization. See
Depreciation and amortization expense discussions below and Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for
additional information.

Uncollectible  Accounts  Recovery,  Net  represents  recoveries  under  the  uncollectible  accounts  tariff.  See  Operating  and  maintenance  expense  discussion
below for additional information on this tariff.

Other revenue includes rental revenue, revenue related to late payment charges, mutual assistance revenues and recoveries of environmental costs associated
with MGP sites. The decrease in Other revenue for the year ended December 31, 2019, as compared to the same period in 2018, primarily reflects absence of
mutual  assistance  revenues  associated  with  hurricane  and  winter  storm  restoration  efforts  that  occurred  in  Q1  2018.  An  equal  and  offsetting  amount  was
included in Operating and maintenance expense.

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

__________
(a) Primarily reflects an increase in discount rates and the favorable impacts of the merger of two of Exelon’s pension plans

effective in January 2019, partially offset by lower than expected asset returns in 2018.

(b) Primarily reflects absence of mutual assistance expenses and decreased contracting costs. An equal and offsetting increase has been recognized in Operating revenues

for the period presented.

(c) ComEd is allowed to recover from or refund to customers the difference between its annual uncollectible accounts expense and the amounts collected in rates annually
through a rider mechanism. ComEd recorded a net decrease in uncollectible accounts for the year ended December 31, 2019, as compared to the same period in 2018,
primarily due to the timing of regulatory cost recovery. An equal and offsetting amount has been recognized in Operating revenues for the periods presented.

Year  Ended  December  31,  2019 Compared  to  Year  Ended  December  31,  2018.  Net  income increased  by  $68  million  primarily  due  to  higher  electric
distribution  rates  that  became  effective  January  2019,  higher  natural  gas  distribution  rates  and  lower  storm  costs,  partially  offset  by  unfavorable  weather
conditions and volume.

Revenues  Net  of  Purchased  Power  and  Fuel  Expense.  There  are  certain  drivers  of  Operating  revenues  that  are  fully  offset  by  their  impact  on  Purchased

PECO

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, 2019 compared to the same period in 2018 RNF was decreased by 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, 2019 and  December 31, 2018 compared  to  the  same  periods  in  2018 and  2017,
respectively, and normal weather consisted of the following:

Pricing for the year ended December 31, 2019 compared to the same period in 2018 increased primarily due to an increase in electric distribution rates charged
to customers. The increase in electric distribution rates was effective January 1, 2019 in accordance with the 2018 PAPUC approved electric distribution rate
case  settlement.  Additionally,  the  increase  represents  revenue  from  higher  natural  gas  distribution  rates.  See  Note  3 —  Regulatory Matters of the Combined
Notes to Consolidated Financial Statements for additional information.

Regulatory  Required  Programs represent  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
Operating and maintenance expense, Depreciation and amortization expense and Income taxes.

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. Transmission revenue for the year ended December 31, 2019 compared to the same period in 2018 decreased primarily
due to lower operating and maintenance expenses and the terms of the settlement agreement approved by FERC in December 2019. 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 and mutual assistance revenues.

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018. Net income attributable to common shareholder increased by $47 million
primarily  due  to  higher  natural  gas  distribution  rates  that  became  effective  January  2019  and  December  2019,  higher  electric  distribution  rates  that  became
effective December 2019, and lower storm costs, partially offset by an increase in various expenses, including interest.

Revenues  Net  of  Purchased  Power  and  Fuel  Expense.  There  are  certain  drivers  to  Operating  revenues  that  are  fully  offset  by  their  impact  on  Purchased
power and fuel expense, such as commodity procurement costs and participation in customer choice programs. BGE recovers electricity, natural gas and other

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.

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  Operating  and  maintenance  expense,  Depreciation  and  amortization  expense  and  Taxes  other  than
income taxes.

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  increased  during  the  year  ended
December 31, 2019 compared to the same period in 2018, primarily due to increases in capital investment and operating and maintenance expense recoveries.

Year  Ended  December  31,  2019 Compared  to  Year  Ended  December  31,  2018.  Net  income increased  by  $38  million primarily  due  to  higher  electric
distribution  rates  in  Maryland  that  became  effective  August  2019  and  June  2018  (not  reflecting  the  impact  of  TCJA),  higher  electric  distribution  rates  in  the
District of  Columbia that  became  effective  August  2018  (not  reflecting  the  impact  of  TCJA), higher  transmission  revenues  due  to  an increase  in transmission
rates  and  the  highest  daily  peak  load,  the  absence  of  the  charge  associated  with  a  remeasurement  of  the  Buzzard  Point  ARO,  and  lower  contracting  costs,
partially offset by an increase in environmental liabilities.

Revenues  Net  of  Purchased  Power  Expense.  There  are  certain  drivers  of  Operating  revenues  that  are  fully  offset  by  their  impact  on  Purchased  power
expense,  such  as  commodity  and  REC  procurement  costs  and  participation  in  customer  choice  programs.  Pepco  recovers  electricity  and  REC  procurement
costs from customers with a slight mark-up. Therefore, fluctuations in these costs have minimal impact on RNF.

Customers  have  the  choice  to  purchase  electricity  from  competitive  electric  generation  suppliers.  Customer  choice  programs  do  not  impact  the  volume  of
deliveries or RNF, but impact Operating revenues related to supplied electricity.

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.

Volume, exclusive of the effects of weather, increased for the year ended December 31, 2019 compared to the same period in 2018 primarily due to the impact
of residential customer growth.

Distribution Revenues increased for the year ended December 31, 2019 compared to the same period in 2018 primarily due to higher electric distribution rates
in Maryland that became effective in August 2019 and June 2018 (not reflecting the impact of TCJA), higher electric distribution rates (not reflecting the impact of
TCJA) in the District of Columbia that became effective in August 2018, partially offset by the accelerated amortization of certain deferred income tax regulatory
liabilities  established  upon  the  enactment  of  TCJA  as  the  result  of  regulatory  settlements.  See  Note  3 —  Regulatory  Matters of  the  Combined  Notes  to
Consolidated Financial Statements for additional information.

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 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  Operating  and  maintenance  expense,  Depreciation  and  amortization  expense,  and  Taxes  other  than
income  taxes.  Revenues  from  regulatory  programs  decreased  for  the  year  ended  December  31,  2019  compared  to  the  same  period  in  2018  due  to  lower
surcharge rates effective January 2019 for energy efficiency programs that were implemented to reflect the impacts of the enactment of TCJA.

Transmission Revenues. 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,

December 31, 2019 compared to the same period in 2018 due to rate increases and an increase in the highest daily peak load.

Other revenue includes revenue related to late payment charges, mutual assistance revenues, off-system sales and service application fees.

Year Ended December 31, 2019 Compared to Year Ended  December 31, 2018. Net income increased by $27 million primarily due to higher transmission
revenues due to an increase in the transmission rates and the highest daily peak load, higher electric distribution rates in Maryland and Delaware that became
effective  throughout  2018  (not  reflecting  the  impact  of  TCJA),  higher  natural  gas  distribution  rates  in  Delaware  that  became  effective  throughout  2018  (not
reflecting the impact of TCJA), and lower write-offs of construction work in progress.

Revenue Decoupling. The demand for electricity is affected by weather and customer usage. However, Operating revenues from electric distribution customers
in Maryland are not affected by unseasonably warmer or colder weather because a bill stabilization adjustment (BSA) that provides for a fixed distribution charge
per customer by customer class. While Operating revenues from electric distribution customers 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, 2019 compared to the same period in  2018, RNF related to weather decreased primarily due to unfavorable weather conditions in
DPL's Delaware 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 20-year period in DPL's Delaware electric service territory and a 30-year period in
DPL's  Delaware  natural  gas  service  territory.  The  changes  in  heating  and  cooling  degree  days  in  DPL’s  Delaware  service  territory  for  the  year  ended
December 31, 2019 compared to same period in 2018 and normal weather consisted of the following:

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018. Net income increased $24 million primarily due to higher electric distribution
rates that became effective April 2019 and higher transmission revenues due to an increase in the transmission rates and the highest daily peak load, partially
offset by lower average residential usage.

Revenues  Net  of  Purchased  Power  Expense.  There  are  certain  drivers  of  Operating  revenues  that  are  fully  offset  by  their  impact  on  Purchased  power
expense, such as commodity and REC procurement costs and participation in customer choice programs. ACE recovers electricity and REC procurement costs
from customers without mark-up. Therefore, fluctuations in these costs have no impact on RNF.

Customers  have  the  choice  to  purchase  electricity  from  competitive  electric  generation  suppliers.  Customer  choice  programs  of  supplier  do  not  impact  the
volume of deliveries or RNF, but impact revenues related to supplied electricity.

The changes in RNF, consisted of the following:

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. During the year ended December 31, 2019 compared to the same period in 2018, RNF related to weather was lower
due to the impact of unfavorable weather conditions in ACE'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 20-year period in ACE’s service territory. The changes in heating  and cooling
degree days in ACE’s service territory for the year ended December 31, 2019 compared to same period in 2018, and normal weather consisted of the following:

(b) Reflects the change in delivery volumes assuming normalized weather based on the historical 20-year average.

Distribution Revenue increased for the year ended December 31, 2019 compared to the same period in 2018 primarily due to higher electric distribution base
rates that became effective in April 2019, partially offset by the accelerated amortization of certain deferred income tax regulatory liabilities established upon the
enactment of TCJA as the result of regulatory settlements. See Note 3 — Regulatory Matters of the Combined Notes to Consolidated Financial Statements for
additional information.

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 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 Operating and maintenance expense, Depreciation and

amortization expense and Taxes other than income taxes. Revenues from regulatory programs decreased for the year ended December 31, 2019 compared to
the same period in 2018 due to rate decreases effective October 2018 for the ACE Transition Bonds.

Transmission Revenues. 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  increased  for  the  year  ended
December 31, 2019 compared to the same period in 2018 primarily due to rate increases and an increase in the highest daily peak load.

Other revenue includes revenue related to late payment charges, mutual assistance revenues, off-system sales and service application fees.

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 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  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

112

 
 
 
Table of Contents

Registrants  have  access  to  credit  facilities  with  aggregate  bank  commitments  of  $10.6  billion.  The  Registrants  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 other postretirement benefit 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, ComEd, PECO, BGE, Pepco, DPL and ACE 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  16 —  Debt  and  Credit  Agreements of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  of  the
Registrants’ debt and credit agreements.

NRC Minimum Funding Requirements

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  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  9 -  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 fund investments 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.

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, the NRC must approve an exemption in order for the plant’s owner(s) to utilize the
NDT fund to pay for non-radiological decommissioning costs (i.e., spent fuel management and site restoration costs). If a unit does not receive this exemption,
the  costs  would  be  borne  by  the  owner(s)  without  reimbursement  from  or  access  to  the  NDT funds.  The  ultimate  costs  for  spent  fuel  management  may  vary
greatly and could be reduced by alternate decommissioning scenarios and/or reimbursement of certain costs under the DOE reimbursement agreements.

As  of  December  31,  2019,  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

113

lives. Additionally, project finance has credit facilities. See Note 16 — Debt and Credit Agreements of the Combined Notes to Consolidated Financial Statements
for additional information on nonrecourse debt.

Cash Flows from Operating Activities

General

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, competitive suppliers, and their ability to achieve operating cost reductions.

See Note 3 — Regulatory Matters and Note 18 — Commitments and Contingencies of the Combined Notes to Consolidated Financial Statements for additional
information of regulatory and legal proceedings and proposed legislation.

Changes in Registrants' cash flows from operations for 2019, 2018 and 2017 were generally consistent with changes in each Registrant’s respective results of
operations, as adjusted for non-cash operating activities, and changes in working capital in the normal course of business. In addition, significant operating cash
flow impacts for the Registrants for 2019, 2018 and 2017 were as follows:

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.

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
Accumulated Benefit Obligation (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 beginning in 2020. 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 other postretirement 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 other postretirement plans in 2020:

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.

Significant investing cash flow impacts for the Registrants for 2019, 2018 and 2017 were as follows:

•

•

•

•

•

•

Variances in capital expenditures are primarily due to the timing of cash expenditures for capital projects. Refer below for additional information on
projected capital expenditure spending.

During  2018,  Exelon  and  Generation  had  expenditures  of  $81  million and  $57  related  to  the  acquisitions of the  Everett  Marine  Terminal  and  the
Handley generating station.

During 2017, Exelon and Generation had expenditures of $23 million and $178 million related to the acquisitions of ConEdison Solutions and the
FitzPatrick nuclear generating station.

During 2018, Exelon and Generation had proceeds of $85 million relating to the sale of Generation’s interest in an electrical contracting business that
primarily installs, maintains and repairs underground and high-voltage cable transmission and distribution services.

During  2017,  Exelon  and  Generation  had  proceeds  of  $218  million  from  sales of  long-lived  assets,  primarily  related  to  the  sale  back  of  turbine
equipment.

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

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

Generation

Approximately 45% of projected 2020 capital expenditures at Generation are for the acquisition of nuclear fuel, with the remaining amounts reflecting additions
and  upgrades  to  existing  generation  facilities  (including  material  condition  improvements  during  nuclear  refueling  outages),  and  additional  investment  in  new
generation facilities.  Generation anticipates that it will fund capital expenditures with internally generated funds and borrowings.

Utility Registrants

Projected 2020 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.  ComEd  and  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. ComEd’s and PECO’s forecasted 2020 capital expenditures
above  reflect  capital  spending  for  remediation  to  be  completed  through  2020.  BGE,  DPL  and  ACE  are  complete  with  their  assessments  and  Pepco  has
substantially completed its assessment and thus do not expect significant capital expenditures related to this guidance in 2020.

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.

Changes in short-term borrowings, net, is driven by repayments on and issuances of notes due in less than 90 days. Refer to Note 16 - Debt and
Credit Agreements of the Combined Notes to Consolidated Financial Statements for additional information on short-term borrowings.

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

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

Exelon issued common stock in  2017  to  fund  the  PHI  merger.  Refer  to  Note  19 -  Shareholders' Equity of  the  Combined  Notes  to  Consolidated
Financial statements for additional information on common stock issuances.

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 18 -  Commitments  and  Contingencies of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  additional  information  on  dividend
restrictions. See below for quarterly dividends declared.

Credit Matters

Market Conditions

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 $7.4 billion was available to support additional commercial paper as of December 31, 2019, 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 market during  2019 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, 2019, it would have been required to provide incremental collateral of $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 $4.2 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

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 16 — 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 22 — 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.

126

 
 
 
 
 
 
 
 
Table of Contents

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  15 —
Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional information on collateral provisions.

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
contribution or borrowing as of December 31, 2019, are presented in the following tables:

Shelf  Registration  Statements.  Exelon,  Generation,  ComEd,  PECO,  BGE,  Pepco,  DPL  and  ACE  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.

Regulatory Authorizations. ComEd, PECO, BGE, Pepco, DPL and ACE are required to obtain short-term and long-term financing authority from Federal and

redemptions or debt issuances. Variable rate interest obligations are estimated based on rates as of December 31, 2019.

(b) Capacity payments associated with contracted generation lease agreements are net of sublease and capacity offsets of $143 million, $98 million, $55 million, $44 million,

$44 million and $223 million for 2020, 2021, 2022, 2023, 2024 and thereafter, respectively and $607 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) Primarily represents commitments to purchase fuel supplies for nuclear and fossil generation, including those related to CENG.
(e) Represents the future estimated value at December 31, 2019 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.
These estimates are subject to significant variability from period to period.

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.

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 2020 through 2022.

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, 2019, the percentage of expected generation hedged for the Mid-Atlantic, Midwest, New
York  and  ERCOT  reportable  segments  is  91%-94% and 61%-64% for  2020 and 2021,  respectively.    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 and BGE 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,
2019 market conditions and hedged position would be decreases in pre-tax net income of approximately $25 million and $331 million, respectively, for 2020 and
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  15 —  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 2020 through  2024 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,

134

Table of Contents

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  15 —  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, 2017 to  December 31, 2019.  It  indicates  the  drivers  behind  changes  in  the  balance  sheet  amounts.  This  table  incorporates  the  mark-to-

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  17 —  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  15—Derivative  Financial
Instruments of the Combined Notes to Consolidated Financial Statements for a detailed discussion of credit risk.

Generation

The  following  tables  provide  information  on  Generation’s  credit  exposure  for  all  derivative  instruments,  normal  purchases  and  normal  sales  agreements,  and
payables and receivables, net of collateral and instruments that are subject to master netting agreements, as of December 31, 2019. The tables further delineate
that exposure by credit rating of the counterparties and provide guidance on the concentration of credit risk to individual counterparties and an indication of the
duration  of  a  company’s  credit  risk  by  credit  rating  of  the  counterparties.  The  figures  in  the  table  below  exclude  credit  risk  exposure  from  individual  retail
customers, uranium procurement contracts, and exposure through RTOs, ISOs and commodity exchanges, which are discussed below.

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  a  provision  for  uncollectible
accounts,  based  upon  historical  experience,  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 provision for uncollectible accounts. See Note 1 — Significant Accounting Policies
of  the  Combined  Notes  to  Consolidated  Financial  Statements  for  the  allowance  for  uncollectible  accounts  policy.  The  Utility  Registrants  did  not  have  any
customers  representing  over  10%  of  their  revenues  as  of  December  31,  2019.  See  Note  3 —  Regulatory Matters of  the  Combined  Notes  to  Consolidated
Financial Statements for additional information.

As of December 31, 2019, ComEd, PECO, BGE, Pepco, DPL and ACE's net credit exposure to suppliers was immaterial. See Note 15 — 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 15 — Derivative Financial Instruments of the Combined Notes to Consolidated Financial Statements for additional
information regarding collateral requirements. See Note 18 — 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, 2019, 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 15 — 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.

139

Table of Contents

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.

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  $5 million decrease  in  Exelon  pre-tax  income  for  the  year  ended
December  31,  2019.  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  15—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, 2019,
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 10% increase in interest rates and decrease in equity prices would result in a $610 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.

A discussion of Generation’s results of operations for 2019 compared to 2018 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  16 —  Debt  and  Credit  Agreements of  the  Combined  Notes  to  Consolidated
Financial Statements of this Form 10-K for additional information.

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, 2019. 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, 2019,  Exelon’s  internal  control  over  financial
reporting was effective.

The  effectiveness  of  Exelon’s  internal  control  over  financial  reporting  as  of  December  31,  2019,  has  been  audited  by  PricewaterhouseCoopers  LLP,  an
independent registered public accounting firm, as stated in their report which appears herein.

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, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 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, 2019, 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,

166

Table of Contents

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 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 9 to the consolidated financial statements, Exelon Generation 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, 2019, the nuclear decommissioning asset retirement
obligation was approximately $10.5 billion.

The principal considerations for our determination that performing procedures relating to Exelon Generation’s annual ARO assessment is a critical audit matter
are there was a significant amount of judgment by management when estimating its decommissioning obligation. This in turn led to significant auditor judgment,
subjectivity, and effort in performing procedures to evaluate management’s cash flow model and significant assumptions, including the decommissioning cost
studies. In addition, the audit effort involved the use of professionals with specialized skill and knowledge to assist in evaluating the audit evidence obtained from
these procedures.

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, including 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 11 to the consolidated financial statements, Exelon Generation 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

167

Table of Contents

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 undiscounted
expected future cash flows include significant unobservable inputs including revenue and generation forecasts and projected capital and maintenance
expenditures. As of December 31, 2019, the total carrying value of long-lived generation assets subject to this evaluation was approximately $24.2 billion.

The principal considerations for our determination that performing procedures relating to Exelon Generation’s impairment assessment of long-lived generation
assets is a critical audit matter are there was a significant amount of judgment by management in assessing the recoverability of these assets or asset groups.
This in turn led to significant auditor judgment, subjectivity and effort in performing procedures to evaluate the audit evidence related to the reasonableness of
management’s significant assumptions used in management's estimates, including revenue and generation forecasts. In addition, the audit effort involved the
use of professionals with specialized skills and knowledge to assist in evaluating the audit evidence obtained from these procedures.

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 of Exelon Generation’s long-lived generation assets or asset groups. These procedures also included, among others, testing
management’s process for developing undiscounted expected future cash flows for long-lived generation assets 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, including revenue and generation forecasts. Professionals with specialized skill and knowledge were used to assist in evaluating the
reasonableness of revenue forecasts.

Level 3 Derivatives Significant Assumptions

As described in Notes 1, 15 and 17 to the consolidated financial statements, Exelon Generation has derivative instruments that include both observable and
unobservable inputs. When valuing Level 3 derivatives, management utilizes various inputs and assumptions including forward commodity prices, commodity
price volatility, contractual volumes, delivery location, interest rates, credit quality of counterparties and credit enhancements. Those derivatives with significant
unobservable inputs are classified as Level 3. As of December 31, 2019, the Company had a level 3 fair value derivative asset position of $957 million and a
level 3 fair value derivative liability position of $140 million.

The principal considerations for our determination that performing procedures relating to the significant assumptions used to value Exelon Generation’s Level 3
derivatives is a critical audit matter are there was a significant amount of judgment by management in determining the inputs and assumptions used to estimate
the fair value of the Level 3 derivatives. This in turn led to significant auditor judgment, subjectivity, and effort in performing procedures to evaluate audit
evidence related to the reasonableness of management’s significant assumptions used in management’s estimates, including forward commodity prices. In
addition, the audit effort involved the use of professionals with specialized skill and knowledge to assist in evaluating the audit evidence obtained from these
procedures.

statements. These procedures included testing the effectiveness of controls relating to management’s development of the inputs, assumptions, and model used

derivatives by evaluating the appropriateness of management’s model, testing the completeness and accuracy of data used by management, and evaluating the
reasonableness of management’s significant assumptions, including forward commodity prices. Professionals with specialized skill and knowledge were used to
assist in evaluating the reasonableness of forward commodity prices.

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

168

Table of Contents

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, 2019, there were $9.5 billion of regulatory assets and $10.4 billion of regulatory
liabilities.

The principal considerations for our determination that performing procedures relating to accounting for the effects of rate regulation is a critical audit matter are
there was a significant amount of judgment by management when assessing the impact of updates in regulation on accounting for new and existing regulatory
assets and liabilities and the evaluation of whether the regulatory assets and liabilities will be recovered and settled, respectively. This in turn led to significant
auditor judgment and audit effort to perform procedures relating to the accounting for the impact of regulatory and legislative proceedings on new and existing
regulatory assets and liabilities.

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 the implementation of new 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 new and updated regulatory guidance and proceedings and the related accounting implications, and
calculating regulatory assets and liabilities based on provisions and formulas outlined in rate orders and other correspondence with regulators.

performing procedures that respond to those risks.  Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
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.

To the Board of Directors and Shareholder of Atlantic City Electric Company

Opinion on the Financial Statements

Report of Independent Registered Public Accounting Firm

We  have  audited  the  consolidated  financial  statements,  including  the  related  notes,  as  listed  in  the  index  appearing  under  Item  15(a)(9)(i),  and  the  financial
statement  schedule  listed  in  the  index  appearing  under  Item  15(a)(9)(ii),  of  Atlantic  City  Electric  Company  and  its  subsidiary  (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, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2019 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.    

Basis for Opinion

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 (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 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.

Our audits 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.  We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company's auditor since 1998.

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

Note 1 — Significant Accounting Policies

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 22 — 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  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,  including  certain  financing  trusts  of  ComEd  and
PECO.  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  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 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. 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.

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, the application of purchase accounting, inventory reserves, allowance
for uncollectible accounts, goodwill and asset impairments, derivative instruments, unamortized energy contracts, fixed asset depreciation, environmental costs
and other loss contingencies, taxes and unbilled energy revenues. Actual results could differ from those estimates.

Prior Period Adjustments and Reclassifications (Exelon, PHI and Pepco)

In the fourth quarter 2019, management identified an error related to an overstatement of the regulatory asset associated with Pepco’s decoupling mechanism
for  Maryland  that  originated  in  2007  upon  the  inception  of  the  program.  Management  has  concluded  that  the  error  was  not  material  to  previously  issued
consolidated  financial  statements  and  the  error  was  corrected  through  a  revision  to  Exelon’s,  PHI’s  and  Pepco’s  consolidated  financial  statements  contained
herein  for  the  years  ended  December  31,  2018  and  2017.  The  impact  of  the  error  correction  was  an  $11 million reduction  to  Exelon’s,  PHI’s  and  Pepco’s
opening Retained earnings as of January 1, 2017 with a corresponding reduction to current Regulatory assets of $18 million and Deferred income taxes and
unamortized investment tax credits of $7 million. In addition, Exelon’s, PHI’s and Pepco’s Total operating revenues decreased by $7 million for the years ended
December  31,  2018  and  2017  and  Net  income  decreased  by  $5 million and  $7 million for  the  years  ended  December  31,  2018  and  2017,  respectively,  from
originally reported amounts. The error did not impact net cash flows provided by operating activities, net cash flows used in investing activities or net cash flows
provided by financing activities for the years ended December 31, 2018 and 2017 for Exelon, PHI and Pepco. Exelon’s diluted earnings per share of common
stock remained unchanged from the originally reported amount for the year ended December 31, 2018. Exelon’s basic earnings per share of common stock for
the year ended December 31, 2018 and basic and diluted earnings per share of common stock for the year ended December 31, 2017 decreased by $0.01 from
the originally reported amount.

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

Note 1 — Significant Accounting Policies

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 settled 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 an offsetting regulatory asset or liability in its Consolidated Balance Sheets. See Note 3
— Regulatory Matters and Note 15 — 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

225

Table of Contents

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

Note 1 — Significant Accounting Policies

state or local governments on the sale or distribution of gas and electricity. 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 23 — Supplemental Financial Information for Generation’s, ComEd’s, PECO’s, BGE’s, Pepco's, DPL's and ACE's utility taxes that
are presented on a gross basis.

Leases (All Registrants)

The Registrants recognize a ROU asset and lease liability for operating leases with a term of greater than one year. The ROU asset is included in Other deferred
debits and other assets and the lease liability is included in Other current liabilities and Other deferred credits and other liabilities 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.

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 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 10 — Leases for additional information.

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

226

benefits in Interest expense or Other income and deductions (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,  2019 and  2018,  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,  2019 and  2018, 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 23 — Supplemental Financial Information for additional information.

Allowance for Uncollectible Accounts (All Registrants)

The allowance for uncollectible accounts reflects the Registrants’ best estimates of losses on the customers' accounts receivable balances. For Generation, the
allowance is based on accounts  receivable aging historical experience and other currently available information. Utility Registrants estimate the allowance by
applying  loss  rates  developed  specifically  for  each  company  to  the  outstanding  receivable  balance  by  customer  risk  segment.  Utility  Registrants'  customer
accounts are written off consistent with approved regulatory requirements. See Note 3 — Regulatory Matters for additional information regarding the regulatory
recovery of uncollectible accounts receivable at ComEd and ACE.

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

227

Table of Contents

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

Note 1 — Significant Accounting Policies

liabilities of a consolidated VIE for which creditors do not have recourse to the general credit of the primary beneficiary.

See Note 22 — 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. Equity securities held in the NDT funds are classified as equity securities with readily
determinable fair values. 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 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. See Note 3 — Regulatory Matters for additional information regarding ComEd’s and PECO’s
regulatory  assets  and  liabilities  and  Note  17 —  Fair  Value  of  Financial  Assets  and  Liabilities and  Note  9 —  Asset  Retirement  Obligations for  additional
information regarding marketable securities held by NDT funds.

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

228

Table of Contents

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

Note 1 — Significant Accounting Policies

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 7 — Property, Plant and Equipment, Note 8 — Jointly Owned Electric Utility Plant and Note  23 — Supplemental Financial Information for additional
information regarding property, plant and equipment.

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 18 — 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. The Utility Registrants' 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. 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 6 — Early Plant Retirements for additional information on the impacts of expected and potential early plant retirements.

See Note 7 — 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.

229

Table of Contents

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

Note 1 — Significant Accounting Policies

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  23 — 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 9 — Asset Retirement Obligations for
additional information.

Guarantees (All Registrants)

The Registrants recognize, at the inception of a guarantee, a liability for the fair market value of the obligations they have undertaken by issuing the guarantee,
including the ongoing obligation to perform over the term of the guarantee in the event that the specified triggering events or conditions occur.

The liability that is initially recognized at the inception of the guarantee 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 18 — 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 11 — 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 tested 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 12 — 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.

230

Table of Contents

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

Note 1 — Significant Accounting Policies

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 decline is 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 15 — 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 15 —
Derivative Financial Instruments for additional information.

Retirement Benefits (All Registrants)

Exelon sponsors defined benefit pension plans and OPEB plans for essentially all 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 14 — Retirement Benefits for additional information.

New Accounting Standards (All Registrants)

New Accounting Standards Adopted in 2019: In 2019, the Registrants adopted the following new authoritative accounting guidance issued by the FASB.

Cloud Computing Arrangements (Issued August 2018). Aligns the requirements for capitalizing costs incurred to implement a cloud computing arrangement with
the internal-use software guidance. As a result, certain implementation costs incurred in a cloud computing arrangement that are currently expensed as incurred
will  be  deferred  and  amortized  over  the  non-cancellable  term  of  the  arrangement  plus  any  reasonably  certain  renewal  periods.  The  standard  was  effective
January  1,  2020  and  can  be  applied  using  either  a  prospective  or  retrospective  transition  approach.  A  retrospective  approach  requires  a  cumulative-effect
adjustment to retained earnings as of

231

Table of Contents

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

Note 1 — Significant Accounting Policies

the beginning of the period of adoption. The Registrants early adopted this standard using a prospective approach as of January 1, 2019. The new guidance did
not have a material impact on the Registrants' financial statements.

Leases (Issued February 2016). The Registrants applied the new guidance with the following transition practical expedients:

•

•

•

a "package of three" expedients that must be taken together and allow entities to (1) not reassess whether existing contracts contain leases, (2) carry
forward the existing lease classification, and (3) not reassess initial direct costs associated with existing leases,

an implementation expedient which allows the requirements of the standard in the period of adoption with no restatement of prior periods, and

a  land  easement  expedient  which  allows  entities  to  not  evaluate  land  easements  under  the  new  standard  at  adoption  if  they  were  not  previously
accounted for as leases.

The standard resulted in the Registrants recording ROU assets and lease liabilities for operating leases in their Consolidated Balance Sheets but did not have a
material impact in the Registrants' Consolidated Statements of Operations and Comprehensive Income, Consolidated Statements of Cash Flows and
Consolidated Statements of Changes in Shareholders' Equity. The operating ROU assets and lease liabilities recognized upon adoption are materially consistent
with the balances presented in the Combined Notes to the Consolidated Financial Statements, excluding 2019 expense and payment activity. See Note 10 —
Leases for additional information.

New Accounting  Standards Adopted as of January 1, 2020: The following new authoritative  accounting  guidance  issued by the  FASB was adopted  as of
January 1, 2020 and will be reflected by the Registrants in their consolidated financial statements beginning in the first quarter of 2020.

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 test, 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 test). Entities will continue to have the
option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The standard was effective January 1, 2020 and must be
applied on a prospective basis. Exelon, Generation, ComEd, PHI and DPL will apply the new guidance for their goodwill impairment assessments in 2020 and
do not expect the updated guidance to have a material impact to their financial statements.

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  interest  in  Nine  Mile  Point  Unit  2.  CENG  is  100%  consolidated  in  Exelon's  and  Generation's
financial statements. See Note 22 — Variable Interest Entities for additional information.

On  April  1,  2014,  Generation  and  EDF  entered  into  various  agreements  including  a  Nuclear  Operating  Services  Agreement,  an  amended  LLC  Operating
Agreement,  an  Employee  Matters  Agreement,  and  a  Put  Option  Agreement,  among  others.  Under  the  amended  Operating  Agreement,  CENG  made  a  $400
million special distribution to EDF

232

Table of Contents

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

Note 2 — Mergers, Acquisitions and Dispositions

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, 2019, the total unpaid aggregate preferred distributions and related return owed to Generation is $571
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, the FERC and the NRC. The process and regulatory approvals could take one to two years or more to complete.

Acquisition of James A. FitzPatrick Nuclear Generating Station (Exelon and Generation)

On March 31, 2017, Generation acquired the single-unit James A. FitzPatrick (FitzPatrick) nuclear generating station located in Scriba, New York from Entergy
Nuclear  FitzPatrick  LLC  (Entergy)  for  a  total  purchase  price  of  $289  million,  which  consisted  of  a  cash  purchase  price  of  $110  million and  a  net  cost
reimbursement to and on behalf of Entergy of $179 million. As part of the transaction, Generation received the FitzPatrick NDT fund assets and assumed the
obligation to decommission FitzPatrick. The NRC license for FitzPatrick expires in 2034. An after-tax bargain purchase gain of $233 million was included within
Exelon's  and  Generation's  Consolidated  Statements  of  Operations  and  Comprehensive  Income  which  primarily  reflects  differences  in  strategies  between
Generation and Entergy for the intended use and ultimate decommissioning of the plant.

Exelon and Generation incurred $57 million of merger and integration related costs for FitzPatrick for the year ended December 31, 2017 which are included
within Operating and maintenance expense in Exelon's and Generation's Consolidated Statements of Operations and Comprehensive Income.

Disposition of Oyster Creek (Exelon and Generation)

On July 31, 2018, Generation entered into an agreement with Holtec International (Holtec) and its indirect wholly owned subsidiary, Oyster Creek Environmental
Protection,  LLC  (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,  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.

As  a  result  of  the  transaction,  in  the  third  quarter  of  2018,  Exelon  and  Generation  reclassified  certain  Oyster  Creek  assets  and  liabilities  in  Exelon’s  and
Generation’s Consolidated Balance Sheets as held for sale at their respective fair values. Exelon and Generation had $897 million and $777 million of Assets
and Liabilities held for sale,  respectively, at December 31, 2018.  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 the third quarter of 2018 and in the second quarter of 2019, respectively. See
Note 9 — Asset Retirement Obligations for additional information.

Note 2 — Mergers, Acquisitions and Dispositions

Disposition of EGTP and Acquisition of Handley Generating Station (Exelon and Generation)

EGTP,  a  Delaware  limited  liability  company,  was  formed  in  2014  with  the  purpose  of  financing  a  portfolio  of  assets  comprised  of  two  combined-cycle  gas
turbines  (CCGTs)  and  three  peaking/simple  cycle  facilities  consisting  of  approximately  3.4 GW  of  generation  capacity  in  ERCOT  North  and  Houston  Zones.
EGTP was an indirect wholly owned subsidiary of Exelon and Generation.

EGTP’s operating cash flows were negatively impacted by certain market conditions and the seasonality of its cash flows. On May 2, 2017, as a result of the
negative impacts of certain market conditions and the seasonality of its cash flows, EGTP entered into a consent agreement with its lenders to permit EGTP to
draw on its revolving credit facility and initiate an orderly sales process to sell the assets of its wholly owned subsidiaries. As a result, Exelon and Generation
classified certain of EGTP assets and liabilities as held for sale at their respective fair values less costs to sell and recorded a $460 million pre-tax impairment
loss. See Note  16  —  Debt  and  Credit  Agreements for  details  regarding  the  nonrecourse  debt  associated  with  EGTP  and  Note  11  —  Asset  Impairments for
additional information.

On November 7, 2017, EGTP and all of its wholly owned subsidiaries filed voluntary petitions for relief under Chapter 11 of Title 11 of the United States Code in
the United States Bankruptcy Court for the District of Delaware, which resulted in Exelon and Generation deconsolidating EGTP's assets and liabilities from their
consolidated financial statements in the fourth quarter of 2017 that resulted in a pre-tax gain upon deconsolidation of $213 million. Concurrently with the Chapter
11  filings,  Generation  entered  into  an  asset  purchase  agreement  to  acquire  one  of  EGTP's  generating  plants,  the  Handley  Generating  Station,  subject  to  a
potential  adjustment  for  fuel  oil  and  assumption  of  certain  liabilities.  In  the  Chapter  11  Filings,  EGTP  requested  that  the  proposed  acquisition  of  the  Handley
Generating Station be consummated through a court-approved and supervised sales process. The acquisition closed on April 4, 2018 for a purchase price of
$62 million.  The  Chapter  11  bankruptcy  proceedings  were  finalized  on  April  17,  2018,  resulting  in  the  ownership  of  EGTP  assets  (other  than  the  Handley
Generating Station) being transferred to EGTP's lenders.

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.  ComEd  is
required to file an annual update to its electric distribution formula rate on or before May 1st, 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).

ComEd’s 2018 approved revenue requirement above reflects a decrease of  $58 million for the initial year revenue requirement for 2018 and an increase of  $34 million
related to the annual reconciliation for 2017. The revenue requirement for 2018 and the annual reconciliation for 2017 provides for a weighted average debt and equity
return on distribution rate base of 6.52%

inclusive of an allowed ROE of 8.69%, reflecting the average rate on 30-year treasury notes plus 580 basis points. ComEd’s 2019 approved revenue requirement above
reflects an increase of $51 million for the initial year revenue requirement for 2019 and a decrease of $68 million related to the annual reconciliation for 2018. The revenue
requirement  for  2019  and  the  annual  reconciliation  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 average rate on 30-year treasury notes plus  580 basis points. See table below for ComEd's regulatory assets associated with its
electric distribution formula rate.

During the first quarter of 2018, ComEd revised its electric distribution formula rate to implement revenue decoupling provisions provided for under FEJA. As a result of
this revision, ComEd’s electric distribution formula rate revenues are not impacted by abnormal weather, usage per customer or numbers of customers. ComEd began
reflecting the impacts of this change in its Operating revenues and electric distribution formula rate regulatory asset in the first quarter of 2017.

Transmission Formula Rates

Transmission Formula Rate (Exelon, ComEd, BGE, PHI, Pepco, DPL and ACE).  ComEd’s, BGE’s, Pepco's, DPL's and ACE's 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, with the resulting rates effective on June 1 of the same year. The annual 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 beginning
June 1 of the prior year and actual costs incurred for that year (annual reconciliation).

(c) Represents the weighted average debt and equity return on transmission rate bases.
(d) As part of the FERC-approved settlement of ComEd’s 2007 transmission rate case, the rate of return on common equity is 11.50%, inclusive of a 50-basis-point incentive
adder for being a member of a RTO, and the common equity component of the ratio used to calculate the weighted average debt and equity return for the transmission
formula  rate  is  currently  capped  at  55%.  As  part  of  the  FERC-approved  settlement  of  the  ROE  complaint  against  BGE,  Pepco,  DPL  and  ACE,  the  rate  of  return  on
common equity is 10.50%, inclusive of a 50-basis-point incentive adder for being a member of a RTO.

Transmission Formula Rate (Exelon and PECO). On May 1, 2017, PECO filed a request with FERC seeking approval to update its transmission rates and
change the manner in which PECO’s transmission rate is determined from a fixed rate to a formula rate. The formula rate will be updated annually to ensure that
under  this  rate  customers  pay  the  actual  costs  of  providing  transmission  services.  PECO’s  initial  formula  rate  filing  included  a  requested  increase  of  $22
million to PECO’s annual transmission revenue requirement, which reflected a ROE of  11%, inclusive of a 50 basis point adder for being a member of a RTO.
On June 27, 2017, FERC issued an Order accepting the filing and suspending the proposed rates until December 1, 2017, subject to refund, and set the matter
for hearing and settlement judge procedures.

On  December  5,  2019,  FERC  issued  an  Order  accepting  without  modification  the  settlement  agreement  filed  by  PECO  and  other  parties  in  July  2019.  The
settlement results in an increase of approximately $14 million with a return on rate base of 7.62% compared to PECO's initial formula rate filing and allows for an
ROE of 10.35%, inclusive of a 50 basis point adder for being a member of the RTO. The settlement did not have a material impact on PECO's 2017, 2018, or
2019  annual  transmission  revenue  requirements.  PECO  will  update  its  rates  in  2020  and  refund  estimated  overcollections  totaling  approximately  $28 million
related to the amounts billed under the proposed rates in effect since 2017.

Pursuant  to  the  transmission  formula  rate  request  discussed  above,  PECO  made  its  annual  formula  rate  updates  in  May  2018  and  2019,  which  included  a
decrease of $6 million and an increase of $8 million, respectively, to the annual transmission revenue requirement. The updated transmission formula rates were
effective on June 1, 2018 and 2019, respectively, subject to refund.

Other State Regulatory Matters

Illinois Regulatory Matters

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  return  on  equity  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 1st 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.

During 2019, the ICC approved the following total increases in ComEd's requested energy efficiency revenue requirement:

related to the annual reconciliation for 2018. The revenue requirement for 2020 provides for a weighted average debt and equity return on the energy efficiency regulatory
asset and rate base of 6.51% inclusive of an allowed ROE of  8.91%,  reflecting  the  average  rate  on  30-year  treasury  notes  plus  580 basis points. See table below for
ComEd's regulatory assets associated with its energy efficiency formula rate.

Maryland Regulatory Matters

Maryland Alternative Rate Plans Rulemaking (Exelon, BGE, PHI, Pepco and DPL). On August 9, 2019, the MDPSC issued an order in which the MDPSC
determined that it is now appropriate to move forward to implement alternative rate plans in Maryland.  The MDPSC found that a multi-year rate plan, based on a
historic test year and allowing up to three future test years, can produce just and reasonable rates.  A working group was convened and submitted a detailed
implementation report related to multi-year rate plans to the MDPSC on December 20, 2019.  In response to the working group report, the MDPSC issued an
order on February 4, 2020 establishing a multi-year rate plan pilot and an associated framework for a Maryland utility to use in the pilot multi-year rate plan filing.
The working group was required to continue and discuss how best to integrate performance-based measures into a multi-year rate plan. The working group is
currently discussing performance-based measures which could be combined with future multi-year rate plans and will submit its report to the MDPSC by April 1,
2020. BGE, Pepco and DPL cannot predict the outcome or the potential financial impact, if any, on BGE, Pepco or DPL.

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  Provider  of  Last  Resort  service,  also  known  as  Standard  Offer  Service  (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. The appeal currently resides with the Maryland Court of Special 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 these appeals.

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  Infrastructure
Investment Program (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.

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  renewable  energy  portfolio  standards.  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. ComEd, Pepco, DPL and ACE had similar transmission-related income tax
regulatory  liabilities  and  assets  also  requiring  FERC  approval.  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. As a result of the FERC's order, ComEd, BGE, Pepco, DPL and
ACE  took  a  charge  to  Income  tax  expense  within  their  Consolidated  Statements  of  Operations  and  Comprehensive  Income  in  the  fourth  quarter  of  2017,
reducing  their  associated  transmission-related  income  tax  regulatory  assets  for  the  portion  of  the  total  transmission-related  income  tax  regulatory  assets  that
would  have  been  previously  amortized  and  recovered  through  rates.  Similar  regulatory  assets  and  liabilities  at  PECO  are  not  subject  to  the  same  FERC
transmission rate recovery formula. See above for additional information regarding PECO's transmission formula rate filing.

On December 18, 2017, BGE filed for clarification and rehearing of FERC’s November 16, 2017 order and 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  BGE’s  December  18,  2017  request  for  rehearing  and  clarification  and  ComEd's,  Pepco's,  DPL's  and
ACE's February 23, 2018 (as amended on July 9, 2018) filings, citing the lack of timeliness of the requests to recover amounts that would have been previously
amortized,  but  indicating  that  ongoing  recovery  of  certain  transmission-related  income  tax  regulatory  assets  would  provide  for  a  more  accurate  revenue
requirement, consistent with its November 16, 2017 order.

On October 1, 2018, ComEd, BGE, Pepco, DPL, and ACE submitted filings to recover ongoing non-TCJA amortization amounts and refund TCJA transmission-
related income tax regulatory liabilities for the prospective period starting on October 1, 2018. In addition, on October 9, 2018, ComEd, Pepco, DPL, and ACE
sought rehearing of FERC's September 7, 2018 order. On November 2, 2018, BGE filed an appeal of FERC's September 7, 2018 order to the Court of Appeals
for the D.C. Circuit. 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. ComEd, BGE, Pepco, DPL, and ACE cannot predict the outcome of these
proceedings.

If FERC ultimately rules that the future, ongoing non-TCJA amortization amounts are not recoverable, Exelon, ComEd, BGE, PHI, Pepco, DPL and ACE would
record additional charges to Income tax expense, which could be

up to approximately $79 million, $51 million, $17 million, $11 million, $4 million, $5 million and $2 million, respectively, as of December 31, 2019.

PJM Transmission Rate Design (All Registrants). On June 15, 2016, several parties, including the Utility Registrants, filed a proposed settlement with FERC
to resolve outstanding issues related to cost responsibility for charges to transmission customers for certain transmission facilities that operate at or above 500
kV.  The  settlement  included  provisions  for  monthly  credits  or  charges  related  to  the  periods  prior  to  January  1,  2016  that  are  expected  to  be  refunded  or
recovered through PJM wholesale transmission rates through December 2025. On May 31, 2018, FERC issued an order approving the settlement. Pursuant to
the order, similar charges for the period January 1, 2016 through June 30, 2018 would also be refunded or recovered through PJM wholesale transmission rates
over the subsequent 12-month period. PJM commenced billing the refunds and charges associated with this settlement in August 2018.

The  Utility  Registrants  recorded  the  following  payables  to/receivables  from  PJM  and  related  regulatory  assets/liabilities  in  2018  and  have  been  refunding  or
recovering  these  amounts  through  electric  distribution  customer  rates.  Generation  recorded  a  $41  million net  payable  to  PJM  and  a  pre-tax  charge  within
Purchased power and fuel expense in Exelon's and Generation's Consolidated Statements of Operations and Comprehensive Income.

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.

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.

On February 14, 2017, two lawsuits were filed in the Northern District of Illinois against the IPA alleging that the state’s ZEC program violates certain provisions
of the U.S. Constitution. Both lawsuits argued that the Illinois ZEC program would distort PJM's FERC-approved energy and capacity market auction system of
setting wholesale prices and sought a permanent injunction preventing the implementation of the program. The lawsuits were dismissed by the district court on
July 14, 2017. On September 13, 2018, the U.S. Circuit Court of Appeals for the Seventh Circuit affirmed the lower court's dismissal of both lawsuits. On January
7, 2019, plaintiffs filed a petition seeking U.S. Supreme Court review of the case, which was denied on April 15, 2019.

New Jersey Regulatory Matters

New Jersey Clean Energy Legislation. On May 23, 2018, New Jersey enacted legislation that established a ZEC program that will provide 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. Selected nuclear plants will receive annual ZEC payments for
each energy year (12-month period from June 1 through May 31) within 90 days after the completion of such energy year. The quantity of ZECs issued will be

determined based on the greater of 40% of the total number of MWh of electricity distributed by the public electric distribution utilities in New Jersey in the prior
year, or the total number of MWh of electricity generated in the prior year by the selected nuclear power plants. The ZEC price is approximately $10 per MWh
during the first 3-year eligibility period. For eligibility periods following the first 3-year eligibility period, the NJBPU has discretion to reduce the ZEC price.

On November 19, 2018, NJBPU issued an order providing for the method and application process for determining the eligibility of nuclear power plants, a draft
method and process for ranking and selecting eligible nuclear power plants, and the establishment of a mechanism for each regulated utility to purchase ZECs
from  selected  nuclear  power  plants.  On  December  19,  2018,  PSEG  filed  complete  applications  seeking  NJBPU  approval  for  Salem  1  and  Salem  2,  of  which
Generation owns a 42.59% ownership interest, to participate in the ZEC program. 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  $53
million for the year ended December 31, 2019. On May 15, 2019, New Jersey Rate Counsel appealed the NJBPU’s decision to the New Jersey Superior Court.
The appeal does not prevent implementation of the ZEC program. Exelon and Generation cannot predict the outcome of the appeal. See Note 6 - Early Plant
Retirements for additional information related to Salem.

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. The New York State Energy Research and
Development Authority (NYSERDA) centrally procures the ZECs through a 12-year contract extending from April 1, 2017 through March 31, 2029, administered
in  six  two-year  tranches.  ZEC  payments  are  made  based  upon  the  number  of  MWh  produced  by  each  facility,  subject  to  specified  caps  and  minimum
performance  requirements.  The  ZEC  price  for  the  first  tranche  was  set  at  $17.48 per  MWh  of  production  and  is  administratively  determined  using  a  formula
based on the social cost of carbon as determined in 2016 by the federal government, subject to pricing adjustments designed to lower the ZEC price based on
increases in underlying energy and capacity prices.  Following the first tranche, the price will be updated bi-annually.  Each Load Serving Entity (LSE) is required
to purchase an amount of ZECs from NYSERDA equivalent to its load ratio share of the total electric energy in the New York Control Area.  Cost recovery from
ratepayers is incorporated into the commodity charges on customer bills.

On  October  19,  2016,  a  coalition  of  fossil-generation  companies  filed  a  complaint  in  federal  district  court  against  the  NYPSC  alleging  that  the  ZEC  program
violates  certain  provisions  of  the  U.S.  Constitution;  specifically,  that  the  ZEC  program  interferes  with  FERC’s  jurisdiction  over  wholesale  rates  and  that  it
discriminates against out of state competitors, which was dismissed by the district court on July 25, 2017. On September 27, 2018, the U.S. Court of Appeals for
the Second Circuit affirmed the lower court's dismissal of the complaint against the ZEC program. On January 7, 2019, the fossil-generation companies filed a
petition seeking U.S. Supreme Court review of the case which was denied on April 15, 2019.

In addition, 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.  Subsequently,  Generation,  CENG  and  the  NYPSC  filed
motions to dismiss the state court action, which were later opposed by the plaintiffs. 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 have until
May 4, 2020 to file their brief.

See Note 6 — Early Plant Retirements for additional information related to Ginna and Nine Mile Point, and Note 2 — Mergers, Acquisitions and Dispositions for
additional information on Generation's acquisition of FitzPatrick.

Ginna  Nuclear  Power  Plant  Reliability  Support  Services  Agreement. In  November  2014,  in  response  to  a  petition  filed  by  Ginna  regarding  the  possible
retirement of Ginna, the NYPSC directed Ginna and Rochester Gas

Note 3 — Regulatory Matters

&  Electric  Company  (RG&E)  to  negotiate  a  RSSA  to  support  the  continued  operation  of  Ginna  to  maintain  the  reliability  of  the  RG&E  transmission  grid  for  a
specified period of time.

On April 8, 2016, FERC accepted Ginna’s compliance filing and on April 20, 2016, the NYPSC accepted the revised RSSA with a term expiring on March 31,
2017. In April 2016, Generation began recognizing revenue based on the final approved pricing contained in the RSSA and also recognized a one-time revenue
adjustment of $101 million representing the net cumulative previously unrecognized amount of revenue retroactive from the April 1, 2015 effective date through
March 31, 2016. A 49.99% portion of the one-time adjustment was removed from Generation’s results of operations as a result of the noncontrolling interests in
CENG.

The RSSA required Ginna to continue operating through the RSSA term. On September 30, 2016, Ginna filed the required notice with the NYPSC of its intent to
continue operating beyond the March 31, 2017 expiry of the RSSA, conditioned upon successful execution of an agreement between Ginna and NYSERDA for
the sale of ZECs under the New York CES. Subject to prevailing over any administrative or legal challenges, it is expected the New York CES will allow Ginna to
continue  to  operate  through  the  end  of  its  current  operating  license  in  2029.  See  Note  6 —  Early  Plant  Retirements for  additional  information  regarding  the
impacts of a decision to early retire a nuclear plant.

Federal Regulatory Matters

PJM and NYISO MOPR Proceedings. PJM and NYISO capacity markets include a Minimum Offer Price Rule (MOPR). If a resource is subjected to a MOPR,
its offer is adjusted to effectively remove the revenues it receives through a 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
continues to apply to certain new gas-fired resources.

In January 2017 and May 2018, EPSA filed pleadings at FERC that generally allege that the NYISO and PJM MOPRs should be expanded to apply to existing
resources including those receiving ZEC compensation under the New Jersey ZEC (Salem), New York CES (FitzPatrick, Ginna and Nine Mile Point) and Illinois
ZES (Quad Cities) programs. 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.  Exelon  filed  protests  at  FERC  in  response  to  each  filing,  arguing  generally  that  ZEC  payments  provide  compensation  for  an  environmental
attribute and are no different than other renewable support programs that have generally not been subject to a MOPR.

On  December  19,  2019,  FERC  issued  an  order  in  the  PJM  MOPR  proceeding  that  broadly  applies  the  MOPR  to  all  new  and  existing  resources  including
nuclear, renewables, demand response, energy efficiency, storage and all resources owned by vertically-integrated utilities, greatly expanding the breadth and
scope  of  PJM’s  MOPR,  effective  as  of  PJM’s  next  capacity  auction,  the  timing  of  which  cannot  be  predicted  at  this  time.  FERC  directed  PJM  to  make  a
compliance  filing  within  90  days.  FERC  has  no  deadline  for  acting  on  PJM’s  compliance  filing.  While  FERC  included  some  limited  exemptions  (generally
available to existing renewable, energy efficiency, demand response, storage and existing vertically-integrated utility resources) in its order, no exemptions were
available  to  state-supported  nuclear  resources.  In  addition,  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. Unless Illinois and New Jersey can implement an FRR program in their PJM zones, the MOPR will apply 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, resulting in higher offers for those units
that may not clear the capacity market.

On January 21, 2020, Exelon, PJM and a number of other entities submitted individual requests for rehearing of FERC’s December 19, 2019 order on the PJM
MOPR. FERC routinely extends the deadline by which it must address requests for rehearing. FERC has not yet acted, and has no deadline by which it must
act, in the NYISO proceeding.

Exelon is currently working with PJM and other stakeholders to pursue the FRR option prior to the next capacity auction in PJM. 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 6 —
Early Plant Retirements. Implementing the FRR program in Illinois will require both legislative

250

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

Note 3 — Regulatory Matters

and regulatory changes. Legislation may be introduced in New Jersey as well. Exelon cannot predict whether such legislative and regulatory changes can be
implemented prior to the next capacity auction in PJM.

If Generation’s state-supported nuclear plants in PJM or NYISO are subjected to the MOPR without compensation under an FRR or similar program, it could
have a material adverse impact on Exelon's and Generation's financial statements.

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,  2019, $42 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.

Peach Bottom Units 2 and 3. On July 10, 2018, Generation submitted a second 20-year license renewal application with the NRC for Peach Bottom Units 2
and 3. Generation anticipates the second license renewal in the first half of 2020. Peach Bottom Units 2 and 3 are currently licensed to operate through 2033
and 2034, respectively. See Note 7 – Property, Plant and Equipment for additional information regarding the estimated useful life and depreciation provisions for
Peach Bottom.

Note 4 — Revenue from Contracts with Customers

4. Revenue from Contracts with Customers (All Registrants)

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 Registrant's 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.

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

253

Table of Contents

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, 2019 and 2018. The Utility Registrants
do not incur any material costs to obtain or fulfill contracts with customers.

Contract Balances (All Registrants)

Contract Assets and Liabilities

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 Accounts receivable, net - Customer, respectively, within Exelon’s and Generation’s Consolidated Balance Sheets.

Generation  records  contract  liabilities  when  consideration  is  received  or  due  prior  to  the  satisfaction  of  the  performance  obligations.  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. Generation records contract liabilities
within Other current liabilities and Other noncurrent liabilities within Exelon’s and Generation’s Consolidated Balance Sheets.

The  following  table  provides  a  rollforward  of  the  contract  assets  and  liabilities  reflected  in  Exelon's  and  Generation's  Consolidated  Balance  Sheets  from

unsatisfied as of December 31, 2019. 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  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.

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’  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.

During  the  first  quarter  of  2019,  due  to  a  change  in  economics  in  our  New  England  region,  Generation  changed  the  way  that  information  is  reviewed  by  the
CODM. The New England region is no longer regularly reviewed as a separate region by the CODM nor is it presented separately in any external information
presented  to  third  parties.  Information  for  the  New  England  region  is  reviewed  by  the  CODM  as  part  of  Other  Power  Regions.  Exelon  and  Generation
retrospectively applied this change.

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, 2019, 2018, and 2017 is as follows:

Note 5 — Segment Information

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.

6. 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,

Note 6 — Early Plant Retirements

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 Three
Mile Island 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, each of these plants could again 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.

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.

On February 2, 2018, Generation announced that it would permanently cease generation operations at the Oyster Creek nuclear plant at the end of its current
operating cycle and permanently ceased generation operations on September 17, 2018.

Note 6 — Early Plant Retirements

As  a  result  of  these  early  nuclear  plant  retirement  decisions,  Exelon  and  Generation  recognized  incremental  non-cash  charges  to  earnings  stemming  from
shortening the expected economic useful lives primarily related to accelerated depreciation of plant assets (including any ARC) and accelerated amortization of
nuclear fuel, as well as operating and maintenance expenses. The total annual impact of these charges by year are summarized in the table below.

In 2019, primarily reflects the net impacts associated with the remeasurements of the TMI ARO in the first and third quarters. In 2018 and 2017, primarily reflects materials
and  supplies  inventory  reserve  adjustments,  employee  related  costs  and  CWIP  impairments  associated  with  the  early  retirement  decisions  for  TMI  and  Oyster  Creek.
Excludes  the  charges  in  the  third  quarter  of  2018  and  second  quarter  of  2019  for  the  ARO  remeasurement  due  to  the  sale  of  Oyster  Creek.  See  Note 2 — Mergers,
Acquisitions and Dispositions and Note 9 — Asset Retirement Obligations for additional information.

Generation’s  Dresden,  Byron,  and  Braidwood  nuclear  plants  in  Illinois  are  also  showing  increased  signs  of  economic  distress,  which  could  lead  to  an  early
retirement,  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.  Exelon  continues  to  work  with  stakeholders  on  state  policy
solutions, while also advocating for broader market reforms at the regional and federal level.

Other 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, at the
end of the then-current capacity commitment for Mystic Units 7 and 8. Mystic Unit 9 was then committed through May 2021.

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 and 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 Everett Marine
Terminal. Those adjustments were reflected in a compliance filing filed 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  March  25,  2019,  ISO-NE  filed  the  Inventoried  Energy  Program,  which  is  intended  to  provide  an  interim  fuel  security  program  pending  conclusion  of  the
stakeholder process to develop a long-term, market-based solution to address fuel security. The Inventoried Energy Program went into effect on August 5, 2019.
On October 7, 2019, requests for rehearing were denied and several parties have appealed to the D.C. Circuit Court. FERC ordered ISO-NE to file long-term,
market-based fuel security rules by October 15, 2019; FERC has granted an extension to April 15, 2020.

The following table provides the balance sheet amounts as of December 31, 2019 for Exelon's and Generation’s significant assets and liabilities associated with
the Mystic Units 8 and 9 and Everett Marine Terminal assets that would potentially be impacted by the failure to adopt long-term solutions for reliability and fuel
security.

To ensure the continued reliable supply of fuel to Mystic Units 8 and 9 while they remain operating, on October 1, 2018, Generation acquired the Everett Marine
Terminal  in  Massachusetts  for  a  purchase  price  of  $81 million,  with  the  majority  of  the  fair  value  allocated  to  Property,  plant  and  equipment  and  no  goodwill
recorded.    Generation  also  settled  its  existing  long-term  gas  supply  agreement,  resulting  in  a  pre-tax  gain  of  $75 million,  which  is  included  within  Purchased
power and fuel expense in Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income.

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 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  anticipated  second  renewal  of  its  operating  licenses.  Beginning  in  2017,  TMI  and  Oyster  Creek  depreciation  provisions  were
based on their 2019 expected shutdown dates. Beginning February 2018, Oyster Creek depreciation provisions were based on its announced shutdown date of
September  2018.  See  Note  3 —  Regulatory Matters for  additional  information  regarding  license  renewals  and  the  Illinois  ZECs  and  Note  6 —  Early Plant
Retirements for additional information on the impacts of early plant retirements.

Note 9 — Asset Retirement Obligations

9. 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, 2018 to December 31, 2019:

Includes  $112 million and  $22 million as  the  current  portion  of  the  ARO  at  December 31, 2019 and  2018,  respectively,  which  is  included  in  Other  current  liabilities  in
Exelon’s and Generation’s Consolidated Balance Sheets.
Includes  $772  million of  ARO  related  to  Oyster  Creek  which  is  classified  as  Liabilities  held  for  sale  in  Exelon's  and  Generation's  Consolidated  Balance  Sheets  at
December 31, 2018. See Note 2 — Mergers, Acquisitions and Dispositions for additional information.

(b)

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; and

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; partially offset by

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.

Note 9 — Asset Retirement Obligations

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 6—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.

The net $77 million decrease in the ARO during 2018 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:

•

•

•

A  decrease  of  approximately  $205 million primarily  due  to  lower  estimated  costs  for  the  construction  of  interim  spent  fuel  storage  at  TMI  and  a  net
decrease  in  estimated  costs  to  decommission  Calvert  Cliffs,  FitzPatrick,  Limerick,  and  Salem  nuclear  units  resulting  from  the  completion  of  updated
cost studies. There was also a decrease due to changes in decommissioning scenarios and their probabilities. These decreases were partially offset by

An increase of approximately $115 million for the impact of the early retirement and the announced pending sale of Oyster Creek which closed on July
1, 2019; and

An increase of approximately $120 million for estimated cost escalation rates, primarily for labor, energy and waste burial costs.

See Note 2 — Mergers, Acquisitions and Dispositions and Note 6—Early Plant Retirements for additional information regarding Oyster Creek.

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

Note 9 — Asset Retirement Obligations

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  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, 2019 and  2018, Exelon and Generation  had NDT funds totaling  $13,353 million and $12,695 million,  respectively.  The  NDT  funds  included
$890 million at December 31, 2018, related to Oyster Creek NDT funds which were classified as Assets held for sale in Exelon's and Generation's Consolidated
Balance Sheets. See Note 2 — Mergers, Acquisitions and Dispositions for additional information. The NDT funds include  $163 million and $144 million for the
current portion of the NDT at December 31, 2019 and 2018, respectively, which are included in Other current assets in Exelon's and Generation's Consolidated
Balance Sheets. See Note 23 — 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 and accretion of the decommissioning obligation, are generally offset within Exelon’s and
Generation’s Consolidated Statements of Operations and Comprehensive Income. For the former ComEd units, decommissioning-related activities are generally
offset within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income as long as the NDT funds are expected to exceed
the  total  estimated  decommissioning  obligation.  For  the  former  PECO  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  to  affiliates  at  Generation.  ComEd  and  PECO  have  recorded  an  equal
noncurrent affiliate receivable from Generation and corresponding regulatory liability.

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. As of December 31, 2019, the NDT funds of each of the former ComEd
units, except for Zion (see Zion Station Decommissioning below), are expected to exceed the related decommissioning obligation for each of the units. 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.

Any  changes  to  the  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.

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 24 — 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.

Note 9 — Asset Retirement Obligations

Zion Station Decommissioning

In  2010,  Generation  completed  an  Asset  Sale  Agreement  (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.  To  reduce  the  risk  of  default  by
ZionSolutions, EnergySolutions has provided a $25 million letter of credit to be used to fund decommissioning costs in the event the NDT assets are insufficient.
EnergySolutions and its parent company have also provided a performance guarantee.

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.  Any  Zion  Station  NDT  funds  remaining  after  the  completion  of  all
decommissioning activities will be returned to ComEd customers in accordance with the applicable orders.

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, 2019 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,
2019 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 low-level radioactive waste); (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 5% 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 5.4% to 6.5% (as compared to a historical 5-year annual average pre-tax
return of approximately 6.7%).

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.

275

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

Note 9 — Asset Retirement Obligations

Generation  filed  its  biennial  decommissioning  funding  status  report  with  the  NRC  on  April  1,  2019  for  all  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.  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.  See  NDT  Funds
section above for additional information.

Generation will file its next annual decommissioning funding status report with the NRC by March 31, 2020 for shutdown reactors, reactors within five years of
shutdown except for Zion Station which is included in a separate report to the NRC submitted by EnergySolutions (see Zion Station Decommissioning above).
This report will reflect the status of decommissioning funding assurance as of December 31, 2019 and will include an update for the retirement of TMI in 2019. A
shortfall  at  any  unit  could  necessitate  that  Exelon  post  a  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,  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. 

The  following  table  provides  a  rollforward  of  the  non-nuclear  AROs  reflected  in  the  Registrants’  Consolidated  Balance  Sheets  from  January  1,  2018 to

__________
(a)

In 2018, Pepco recorded an increase of $22 million in Operating and maintenance expense primarily related to asbestos identified at its Buzzard Point property as part of
an annual ARO study. Buzzard Point is a waterfront property in the District of Columbia occupied by an active substation and former Pepco operated steam plant building,
which Pepco retired and closed in 1981.

(b) For ComEd and PECO, the majority of the accretion is recorded as an increase to a regulatory asset due to the associated regulatory treatment.

11. Asset Impairments (Exelon, Generation and PHI)

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.

Equity Method Investments in Certain Distributed Energy Companies (Exelon and Generation)

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. 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 22 — Variable Interest Entities for additional information.

Antelope Valley Solar Facility (Exelon and Generation)

Generation’s Antelope Valley, a 242 MW solar facility in Lancaster, CA, sells all of its output to PG&E through a PPA. As of December 31, 2019, Generation had
approximately $725 million of net long-lived assets related to Antelope Valley. 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. Significant changes
in assumptions such as the likelihood of the PPA being rejected as part of the bankruptcy proceedings could potentially result in future impairments of Antelope
Valley’s net long-lived assets, which could be material.

Antelope Valley is a wholly owned indirect subsidiary of EGR IV, which had approximately $1,893 million of additional net long-lived assets as of December 31,
2019. EGR IV is a wholly owned indirect subsidiary of Exelon and Generation and includes Generation's interest in EGRP and other projects with non-controlling
interests. To date, there have been no indicators to suggest that the carrying amount of other net long-lived assets of EGR IV may not be recoverable.

Generation will continue to monitor the bankruptcy proceedings for any changes in circumstances that may indicate the carrying amount of the net long-lived
assets of Antelope Valley or other long-lived assets of EGR IV may not be recoverable.

See Note 16 — Debt and Credit Agreements for additional information on the PG&E bankruptcy.

New England Asset Group (Exelon and Generation)

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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  ISO-NE  of  the  early  retirement  of  its  Mystic  Generating  Station's  Units  7,  8,  9  and  the  Mystic  Jet  Unit  (Mystic  Generating  Station  assets)  absent
regulatory reforms. These events suggested that the carrying value of its New England asset group may be impaired. Generation completed a comprehensive
review of the estimated undiscounted future cash flows of the New England asset group and no impairment charge was required. Further developments such as
the failure of ISO-NE to adopt long-term solutions for reliability and fuel security could potentially result in material future impairments of the New England asset
group. See Note 6 — Early Plant Retirements for additional information.

District of Columbia Sponsorship (Exelon and PHI)

In the third quarter of 2015, PHI entered into a sponsorship agreement with the District of Columbia for future sponsorship rights associated with public property
within the District of Columbia, which Exelon and PHI had recorded as a finite-lived intangible asset as of December 31, 2016. The specific sponsorship rights
were to be determined  through  future negotiations.  In the fourth quarter of 2017, based upon the lack of available sponsorship opportunities  at that time, the
asset  was  written  off  and  a  pre-tax  impairment  charge  of  $25  million was  recorded  within  Operating  and  maintenance  expense  in  Exelon’s  and  PHI's
Consolidated Statements of Operations and Comprehensive Income.

ExGen Texas Power (Exelon and Generation)

On May 2, 2017, EGTP entered into a consent agreement with its lenders to initiate the sale of the assets of its wholly owned subsidiaries. As a result, Exelon
and  Generation  classified  certain  of  EGTP's  assets  and  liabilities  as  held  for  sale  at  their  respective  fair  values  less  costs  to  sell  and  recorded  a  pre-tax
impairment  charge  in  2017  of  $460 million within  Operating  and  maintenance  expense  in  their  Consolidated  Statements  of  Operations  and  Comprehensive
Income. On November 7, 2017, EGTP and its wholly owned subsidiaries filed voluntary petitions for relief under Chapter 11 of Title 11 of the United States Code
in the United States Bankruptcy Court for the District of Delaware and, as a result, Exelon and Generation deconsolidated EGTP's assets and liabilities from their
consolidated financial statements. See Note 2 — Mergers, Acquisitions and Dispositions for additional information.

12. Intangible Assets (Exelon, Generation, ComEd, PHI, Pepco, DPL and ACE)

Goodwill

The  following  table  presents  the  gross  amount  of  goodwill,  accumulated  impairment  loss  and  carrying  amount  of  goodwill  of  Exelon,  ComEd  and  PHI  as  of
December  31,  2019 and  2018.  There  were  no  additions,  impairments  or  measurement  period  adjustments  during  the  years  ended  December  31,  2019 and
2018.

__________
(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 tested 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 testing 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

Note 12 — Intangible Assets

performed. If an entity bypasses the qualitative assessment, a quantitative two-step, fair value-based test is performed. The first step 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 second step is performed. The
second step requires an allocation of fair value to the individual assets and liabilities using purchase price allocation authoritative guidance in order to determine
the implied fair value of goodwill.

Application  of the  goodwill impairment  test 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.  In  applying  the  second  step,  if  needed,  management  must
estimate the fair value of specific assets and liabilities of the reporting unit.

2019 and  2018 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, 2019 and 2018 for ComEd and as of
November 1, 2019 for PHI. The last quantitative assessments performed were as of November 1, 2016 for ComEd and November 1, 2018 for PHI.

PHI performed a quantitative test for its 2018 annual goodwill impairment assessment as of November 1, 2018. The first step of the test comparing the estimated
fair values of the Pepco, DPL and ACE reporting units to their carrying values, including goodwill, indicated no impairments of goodwill; therefore, no second
step was required.

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. Based on the results of the last quantitative goodwill test performed, the estimated fair values of the ComEd, Pepco, DPL and ACE reporting
units  would  have  needed  to  decrease  by  more  than  30%,  30%,  20% and  30%,  respectively,  for  ComEd  and  PHI  to  fail  the  first  step  of  their  respective
impairment tests.

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
deferred debits and other assets in their Consolidated Balance Sheets, consisted of the following as of December 31, 2019 and 2018. The intangible assets and

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) Exelon established a liability for an uncertain tax position associated with the tax deductibility of certain merger commitments incurred by Exelon in connection with the
acquisitions of Constellation and PHI. In 2017, as a part of its examination of Exelon's return, the IRS National Office issued guidance concurring with Exelon's position
that the merger commitments were deductible. As a result, Exelon, Generation, PHI, Pepco, DPL, and ACE decreased their liability for unrecognized tax benefits by $146
million, $19 million, $59 million, $21 million, $16 million and  $22 million,  respectively,  resulting  in  a  benefit  to  Income  taxes  on  Exelon's,  Generation's,  PHI's,  Pepco's,
DPL's, and ACE's Consolidated Statements of Operations and Comprehensive Income and corresponding decreases in their effective tax rates.

(b) 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.

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 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.

On December 22, 2017, President Trump signed the TCJA into law. Pursuant to the enactment of the TCJA, the Registrants remeasured their existing deferred
income tax balances as of December 31, 2017 to reflect the decrease in the corporate income tax rate from 35% to 21%, which resulted in a material decrease
to their net deferred income tax liability balances as shown in the table below. Generation recorded a corresponding net decrease to income tax expense, while
the Utility Registrants recorded 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  one-time  impacts  recorded  by  the  Registrants  to  remeasure  their  deferred  income  tax  balances  at  the  21% corporate  federal  income  tax  rate  as  of

Note 13 — Income Taxes

State Income Tax Law Changes

Illinois - On June 5, 2019, the Governor of Illinois signed a tax bill which would increase the Illinois corporate income tax rate from 9.50% to 10.49% effective for
tax years beginning on or after January 1, 2021. The tax rate is contingent upon ratification of state constitutional amendments in November 2020. The effect of
the rate change will be recognized in the period in which the new legislation is enacted. Exelon, Generation and ComEd do not expect a material impact to their
financial statements as a result of the rate change.

In 2017, Exelon reviewed and updated its marginal state income tax rates based on 2016 state apportionment rates. In addition, Exelon, Generation and ComEd
recorded  the  impacts  of  Illinois’  statutory  rate  change,  which  increased  the  total  corporate  income  tax  rate  from  7.75% to  9.50% effective  July  1,  2017.  The
following table provides the one-time impact of the rate changes in 2017 for Exelon, Generation and ComEd:

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 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.

There were no material adjustments to income tax expense in 2017 as a result of changes in state apportionment.

Allocation of Tax Benefits (All Registrants)

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  benefit  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 federal tax benefits from Exelon under the Tax Sharing Agreement.

Research and Development Activities

In the fourth quarter 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.

Note 13 — Income Taxes

14. 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,  most  newly-hired  Generation  and  BSC  non-represented,  non-
craft, 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,  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  2019,  Exelon  received  an  updated  valuation  of  its  pension  and  OPEB  to  reflect  actual  census  data  as  of  January  1,  2019. This
valuation  resulted  in  an  increase  to  the  pension  and  OPEB  obligations  of  $75  million and  $36  million,  respectively.  Additionally,  accumulated  other
comprehensive loss increased by $39 million (after-tax) and regulatory assets and liabilities increased by $53 million and decreased by $5 million, respectively.

The majority of the 2019 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 4.31%. The majority of the 2019 OPEB cost is calculated using an expected long-term rate of return on plan assets of 6.67% for funded
plans and a discount rate of 4.30%.

A  portion  of  the  net  periodic  benefit  cost  for  all  plans  is  capitalized  within  the  Consolidated  Balance  Sheets.  The  following  tables  present  the  components  of

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. As a result of new pension guidance effective on January 1, 2018, certain
balances have been reclassified on Exelon’s Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2017. 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 the years ended December 31, 2019 and December 31, 2018 and in Other, net and Property,
plant and equipment, net, for the year ended December 31, 2017. For Generation and the Utility Registrants, the service cost and non–service cost components
are included

Components of AOCI and Regulatory Assets

Exelon recognizes the overfunded or underfunded status of defined benefit pension and OPEB plans as an asset or liability on its balance sheet, with offsetting
entries  to  AOCI  and  regulatory  assets  (liabilities).  A  portion  of  current  year  actuarial  gains  and  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,  2019, 2018 and  2017 for  all  plans
combined.

For pension benefits, Exelon amortizes its unrecognized prior service costs and certain actuarial gains and losses, as applicable, based on participants’ average
remaining service periods.

For  OPEB,  Exelon  amortizes  its  unrecognized  prior  service  costs  over  participants’  average  remaining  service  period  to  benefit  eligibility  age  and  amortizes
certain actuarial gains and losses over participants’ average remaining service period to expected retirement. The resulting average remaining service periods
for pension and OPEB were as follows:

The measurement of the plan obligations and costs of providing benefits under Exelon’s defined benefit and other postretirement 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 selecting 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, 2018, Exelon’s mortality assumption
was supported  by an actuarial  experience study  of Exelon's plan  participants and utilized the IRS's RP–2000  base table  projected  to 2012  with improvement
scale AA and projected thereafter with generational improvement scale BB two-dimensional adjusted to a 0.75% long-term rate reached in 2027. For the year
ended December 31, 2019, Exelon's mortality assumption utilizes the Society of Actuaries' 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,  2019 and  2018.  Assumptions  used  to
determine year-end benefit obligations are the assumptions used to estimate the subsequent year’s net periodic benefit costs.

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 beginning in 2020.
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 other postretirement 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.

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 other postretirement 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,  2019 were  18.80% and  14.40%,  respectively,  compared  to  an  expected  long-term  return  assumption  of
7.00% and 6.67%, respectively. Exelon used an EROA of 7.00% and 6.69% to estimate its 2020 pension and OPEB costs, respectively.

Exelon’s pension and OPEB plan target asset allocations at December 31, 2019 and 2018 were as follows:

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, 2019. 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, 2019, there were no significant concentrations (defined as greater than 10% of plan assets) of risk in
Exelon’s pension and OPEB plan assets.

Includes derivative instruments of $2 million and less than  $1 million, which have a total notional amount of $6,668 million and $5,991 million at December 31, 2019 and
2018, respectively. The notional principal amounts for these instruments provide one measure of the transaction volume outstanding as of the fiscal years ended and do
not represent the amount of the company’s exposure to credit or market loss.

(c) Excludes net liabilities of $120 million and $44 million at December 31, 2019 and 2018, respectively, which are required to reconcile to the fair value of net plan assets.

These items consist primarily of receivables or payables related to pending securities sales and purchases, interest and dividends receivable.

There were no significant transfers between Level 1 and Level 2 during the year ended December 31, 2019 for the 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 17 - 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 seeking to maximize absolute returns using a broad
range  of  strategies  to  enhance  returns  and  provide  additional  diversification.  The  fair  value  of  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  the  years  ended

15. 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

Note 15 — Derivative Financial Instruments

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  referencing  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 that 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.

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

Note 15 — Derivative Financial Instruments

Economic Hedges (Commodity Price Risk)

Generation. For the years ended December 31, 2019, 2018 and 2017, 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, 2019,
the percentage of expected generation hedged for the Mid-Atlantic, Midwest, New York and ERCOT reportable segments is 91%-94% and 61%-64% for 2020
and 2021, respectively.

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, 2019, 2018 and 2017,
net  pre-tax  commodity  mark-to-market  gains  (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 $1,269 million and $1,420 million at December 31, 2019 and 2018, respectively, for Exelon and $569 million and $620 million at December 31, 2019 and
2018, 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  $231 million and  $268 million at  December 31, 2019 and  2018,
respectively.

The mark-to-market derivative assets and liabilities as of December 31, 2019 and 2018 and the mark-to-market gains (losses) for the years ended December 31,
2019, 2018 and 2017 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

309

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.

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,  2019.  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, 2019, credit collateral held from counterparties where Generation had credit exposure included $25 million of cash and $81 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, 2019, the Utility Registrants’ counterparty credit
risk with suppliers was immaterial.

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

Note 15 — Derivative Financial Instruments

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.

The aggregate fair value of all derivative instruments with credit-risk related contingent features in a liability position that are not fully collateralized (excluding
transactions on the exchanges that are fully collateralized) is detailed in the table 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 a Registrant 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, 2019 and 2018, 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, and DPL’s credit rating. As of December 31, 2019,
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, 2019, they could have been required to post incremental collateral to its counterparties of $44 million, $50 million, and $11 million, respectively.

Borrowings under Exelon Corporate’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:

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. 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, 2019 and December 31, 2018, $79 million in variable rate demand bonds issued by DPL were outstanding and are included in the Long-term debt
due within one year in Exelon's, PHI's and DPL's Consolidated Balance Sheet.

Debt Covenants

As of December 31, 2019, the Registrants are in compliance with debt covenants, except for Antelope Valley's nonrecourse debt event of default as discussed
below.

Nonrecourse Debt 

Exelon  and  Generation  have  issued  nonrecourse  debt  financing,  in  which  approximately  $2.8 billion of  generating  assets  have  been  pledged  as  collateral  at
December 31, 2019. 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,  2019,  approximately  $485  million was  outstanding.  In  addition,  Generation  has  issued  letters  of  credit  to  support  its  equity
investment  in  the  project.  As  of  December 31, 2019,  Generation  had  $38 million in  letters  of  credit  outstanding  related  to  the  project.  In  2017,  Generation’s
interests in Antelope Valley were also contributed to and are pledged as collateral for the EGR IV financing structure 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 provides 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 ongoing event of default and 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  and
continues to be classified as current as of December 31, 2019. Further, distributions from Antelope Valley to EGR IV are currently suspended.

Continental Wind.    In September 2013, Continental Wind, LLC (Continental Wind), an indirect subsidiary of Exelon and Generation, completed the issuance
and sale of $613 million senior secured notes. Continental Wind owns

Note 16 — Debt and Credit Agreements

and operates a portfolio of wind farms in Idaho, Kansas, Michigan, Oregon, New Mexico and Texas with a total net capacity of 667MW. 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, 2019, $447 million was outstanding.

In  addition,  Continental  Wind  entered  into  a  $131 million letter  of  credit  facility  and  $10 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, 2019, the Continental Wind letter of credit facility had $115
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 22 - 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, 2019, $106 million was outstanding.

In 2017, Generation’s interests in Renewable Power Generation were contributed to EGRP. Refer to Note 22 - Variable Interest Entities for additional information
on EGRP.

SolGen.    In September 2016, SolGen, LLC (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, 2019, $131 million was outstanding. In
2017, Generation’s interests in SolGen were also contributed to and are pledged as collateral for the EGR IV financing structure referenced below.

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. Generation’s interests in EGRP, Antelope Valley, SolGen, and Albany Green Energy were all contributed to and are
pledged as collateral for this financing. The net proceeds of $785 million, after the initial funding of $50 million for debt service and liquidity reserves as well as
deductions for original discount and estimated costs, fees and expenses incurred in connection with the execution and delivery of the credit facility agreement,
were distributed to Generation for general corporate purposes. The $50 million of debt service and liquidity reserves was treated as restricted cash in Exelon’s
and Generation’s Consolidated Balance Sheets and Consolidated Statements of Cash Flows. The loan is scheduled to mature on November 28, 2024. The term
loan bears interest at a variable rate equal to LIBOR + 3%, subject to a 1% LIBOR floor with interest payable quarterly. As of December 31, 2019, $796 million
was outstanding. 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.

Although Antelope Valley’s debt is in default, it is nonrecourse to EGR IV. However, if in the future Antelope Valley were to file for bankruptcy protection as a
result of events culminating from PG&E’s bankruptcy proceedings this would represent an event of default for EGR IV’s debt that would provide the lender with
an opportunity to accelerate EGR IV’s debt. See Note 22 - Variable Interest Entities for additional information on EGRP.

17. Fair Value of Financial Assets and Liabilities (All Registrants)

Exelon measure and records 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.

322

Table of Contents

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

Note 17 — Fair Value of Financial Assets and Liabilities

•

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.

Fair Value of Financial Liabilities Recorded at the Carrying Amount

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, 2019 and 2018. 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.

Note 17 — Fair Value of Financial Assets and Liabilities

Valuation

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.

Debt rates are reset on a regular basis and the carrying value approximates fair value.

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

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.

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 2030.

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
and include unobservable inputs such as cost, operating results, and discounted cash flows. 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. Private credit fund investments
with multiple investors 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. 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.  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  valued  by  investment  managers  on  a
periodic  basis  using  pricing  models  that  use  independent  appraisals  from  sources  with  professional  qualifications.  These  valuation  inputs  are  not  highly
observable. 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, 2019. 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,
2019, there were no significant concentrations (generally defined as greater than 10 percent) of risk in Generation's NDT assets.

See  Note  9 —  Asset  Retirement  Obligations for  additional  information  on  the  NDT  fund  investments.  See  Note  14 —  Retirement Benefits for  the  valuation
techniques used for hedge fund investments.

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

Note 17 — Fair Value of Financial Assets and Liabilities

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.

Mark-to-Market Derivatives (Exelon, Generation, ComEd, PHI and DPL). 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. 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  its  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.

Note 17 — Fair Value of Financial Assets and Liabilities

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 $2.22 and $0.54 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  15 —  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 and ranges are the same for the asset and liability positions.
(b) The  fair  values  do  not  include  cash  collateral  posted  on  level  three  positions  of  $214  million and  $76  million as  of  December  31,  2019 and  December  31,  2018,

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.

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 $127 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, 2019, 27 MWs of new generation were developed and Exelon and Generation have incurred costs of $120 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  $69 million
guaranteed by Exelon and PHI, of which $23 million, $29 million and $18 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, 2019, the current liability limit per incident
is $13.9 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 $13.5 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. Exelon’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 $13.9 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  22 —  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  $136 million for  2019,  and  was  $58 million and  $60 million for  2018 and  2017,  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  $334 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 18 — 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 Exelon 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  2030  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  2017  to  provide  for  the
reimbursement of SNF storage costs through December 31, 2019. Generation expects the terms for each of the settlement agreements to be extended during
2020 for another three years to cover 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 has received cumulative cash reimbursements for costs incurred as follows:

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, 2019 was 1.551% for the deferred amount transferred from ComEd and 1.879% 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 2025.

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 2022.

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 2021.

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, 2019 and 2018, the Registrants had accrued the following undiscounted amounts for environmental liabilities in Other current liabilities and

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.

Note 18 — Commitments and Contingencies

In September 2018, the EPA issued its Record of Decision (ROD) Amendment for the selection of the final remedy. The ROD modified the EPA’s previously
proposed  plan  for  partial  excavation  of  the  radiological  materials  by  reducing  the  depths  of  the  excavation.  The  ROD  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 in the 2020 - 2021 time frame. In March 2019 the PRPs received Special Notice Letters from the EPA to perform the Remedial Action
work. On October 8, 2019, Generation 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  remediation
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 Generation’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
possess 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
$20  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 or the extent to which,
if 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 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. The DOJ has not yet formally advised the PRPs of the amount that it is seeking, but it is believed to be approximately $90 million from all PRPs.
Pursuant  to  a  series  of  annual  agreements  since  2011,  the  DOJ  and  the  PRPs  have  tolled  the  statute  of  limitations  until  February  2020  so  that  settlement
discussions could proceed. 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

344

Table of Contents

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

Note 18 — Commitments and Contingencies

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  and  on
October 4, 2019 released this document for review and comment by the public. The 45 day comment period ended on November 18, 2019 and a public meeting
was  held  by  Pepco  on  November  2,  2019.  Pepco  and  Generation  will  proceed  to  develop  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.

DOEE will then prepare a Proposed Plan and issue a Record of Decision identifying any further response actions determined to be necessary, after considering
public comment on the Proposed Plan. 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. DOEE asked Pepco, along with parties responsible for
other sites along the river, to participate in a "Consultative Working Group" to provide input into the process for future remedial actions and to ensure proper
coordination with the other river cleanup efforts currently underway, including cleanup of the river segment adjacent to the Benning Road site resulting from the
Benning Road site RI/FS. In addition, the District of Columbia Council directed DOEE to form an official advisory committee made up of members of federal,
state and local environmental regulators, community and environmental groups and various academic and technical experts to provide guidance and support to
DOEE  as  the  project  progressed.  This  group,  called  the  Anacostia  Leadership  Council,  has  met  regularly  since  it  was  formed.  Pepco  has  participated  in  the
Consultative Working Group. In April 2018, DOEE released a draft RI report for public review and comment. Pepco submitted written comments to 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 based on DOEE’s stated position following a series of meetings attended by representatives from the Anacostia Leadership
Council and the Consultative Working Group. On December 27, 2019, DOEE released a Focused Feasibility Study (FFS) and a Proposed Plan (PP) for review
and comment by the public which will be the basis for the Interim ROD, which is expected to be completed in September 2020. The FFS and PP are consistent
with the DOEE’s stated position to follow an adaptive management approach which will allow 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. The comment period ends on March 2, 2020 and a public meeting will be held
on January 23, 2021. Pepco concluded that incremental exposure remains reasonably possible, however 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,  there  is  a  complementary  statutory  program  that  requires  an  assessment  to
determine if any natural resources have been damaged as a result of the contamination that is being remediated, and, if so, that a plan be developed by the
federal, state and local Natural Resource Damage Trustees, who are defined by CERCLA as the responsible parties for the restoration or compensation for any
loss of those resources from the environmental contaminants at the site. If natural resources cannot be restored, then compensation for the injury can be sought
from the responsible parties. The assessment of Natural Resource Damages (NRD) typically takes place following cleanup because cleanups sometimes also
effectively restore habitat. During the second quarter of 2018, Pepco became aware that the Trustees are in the beginning stages of this 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, 2019 and 2018, Exelon and Generation had recorded estimated liabilities of approximately $83 million and $79 million, respectively, in total for
asbestos-related bodily injury claims. As of December 31, 2019, approximately $26 million of this amount related to  263 open claims presented to Generation,
while the remaining $57 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 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.

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

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  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  deadline  for  appeal  is  March  9,  2020.  Generation  continues  to  believe  that  the  City’s  claim  lacks  merit.  Accordingly,  Generation  has  not
recorded a liability for payment resulting from such a revocation, nor can Generation estimate a reasonably possible range of loss, if any, associated with any
such  revocation.  Further,  it  is  reasonably  possible  that  property  taxes  assessed  in  future  periods,  including  those  following  the  expiration  of  the  current  TIF
Agreement in 2020, could be material to Generation’s financial statements.

Subpoenas (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 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 U.S. Attorney's Office for the Northern District of Illinois requiring production of records of any communications
with  certain  individuals  and  entities.  On  October  22,  2019,  the  SEC  notified  Exelon  and  ComEd  that  it  has  also  opened  an  investigation  into  their  lobbying
activities.  Exelon  and  ComEd  have  cooperated  fully  and  intend  to  continue  to  cooperate  fully  and  expeditiously  with  the  U.S.  Attorney’s  Office  and  the  SEC.
Exelon and ComEd cannot predict the outcome of the U.S. Attorney's Office or the SEC investigations. No loss contingency has been reflected in Exelon's and
ComEd's  consolidated  financial  statements  as  this  contingency  is  neither  probable  nor  reasonably  estimable  at  this  time.  Management  is  currently  unable  to
estimate a range of reasonably possible loss as these matters are subject to change.

Subsequent to Exelon announcing the receipt of the subpoenas, a putative class action lawsuit has been filed against Exelon and certain officers of Exelon and
ComEd  alleging  misrepresentations  or  omissions  by  Exelon  purporting  to  relate  to  matters  that  are  the  subject  of  the  subpoenas  and  the  SEC
investigation.  Exelon  believes  that  these  claims  lack  merit  and  intends  to  defend  against  them,  and  though  the  costs  or  any  loss  associated  with  the  lawsuit
cannot be reasonably estimated at this time, Exelon does not believe that the lawsuit will have a material adverse impact on Exelon’s or ComEd’s consolidated
financial statements.

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.

In  June  2014,  Exelon  issued  $1.15 billion of  junior  subordinated  notes  in  the  form  of  23 million equity  units.  In  June  2017,  Exelon  settled  the  forward  equity
purchase  contract  on  these  equity  units  through  issuance  of  33 million shares  of  common  stock  from  treasury  stock,  which  triggered  full  dilution  in  the  EPS
calculation. Previously, the equity units were included in the calculation of diluted EPS using the treasury stock method.

Share Repurchases

There currently is no Exelon Board of Director authority to repurchase  shares. Any previous shares repurchased  are held as treasury shares, at cost, unless
cancelled or reissued at the discretion of Exelon’s management.

20. 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, 2019, there were approximately 12 million shares authorized for issuance under the LTIP. For the years ended  December 31, 2019, 2018 and
2017, 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.

The  following  table  presents  the  stock-based  compensation  expense  included  in  Exelon's  and  Generation's  Consolidated  Statements  of  Operations  and
Comprehensive Income. The Utility Registrants' stock-based compensation expense for the years ended December 31, 2019, 2018 and 2017 was not material.

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.

Note 20 — Stock-Based Compensation Plans

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.

remaining weighted-average period of 1.6 years.

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 immediately upon the date of grant or through the date at
which the employee reaches retirement eligibility. Exelon processes forfeitures as they occur for employees who do not complete the requisite service period.

Stock Options

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, 2019 all stock options were vested and there were no unrecognized compensation costs.

At December 31, 2019 and 2018, 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.

Consolidated VIEs

The table below shows the carrying amounts and classification of the consolidated VIEs’ assets and liabilities included in the consolidated financial statements of
Exelon, Generation, PHI and ACE as of December 31, 2019 and  2018. The assets, except as noted in the footnotes to the table below, can only be used to
settle obligations of the VIEs. The liabilities, except as noted in the footnotes to the table below, are such that creditors, or beneficiaries, do not have recourse to
the general credit of Exelon, Generation, PHI and ACE.

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

As of December 31, 2019 and 2018, Exelon's and Generation's consolidated VIEs consist of:

Consolidated VIE or VIE groups:

Reason entity is a VIE:

CENG - A joint venture between Generation and EDF.
Generation has a 50.01% equity ownership in CENG. See
additional discussion below.
EGRP - A collection of wind and solar project entities.
Generation has a 51% equity ownership in EGRP. See
additional discussion below.
Blue Stem Wind - A Tax Equity structure which is
consolidated by EGRP. Generation is a minority interest
holder.
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. See note 11- Asset Impairments for additional
information.

Disproportionate relationship between equity interest and
operational control as a result of the Nuclear Operating
Services Agreement (NOSA) described further below.
Similar structure to a limited partnership and the limited
partners do not have kick out rights with respect to the

Note 22 — Variable Interest Entities

Reason Generation is primary beneficiary:

Generation conducts the operational activities.

Generation conducts the operational activities.

Generation conducts the operational activities.

Generation conducts all activities.

Generation conducts the operational activities.

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.  See  Note  2  —  Mergers,  Acquisitions  and
Dispositions for additional information.

Exelon and Generation, where indicated, provide the following support to CENG:

•

•

•

•

Generation provided a $400 million loan to CENG. The remaining balance was fully paid by CENG in January 2019.

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 18 — 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. Generation
provides operating and capital funding to the solar and wind entities for ongoing construction, operations and maintenance and there is limited recourse related
to Generation related to certain solar and wind entities.

In 2017, Generation’s interests in EGRP were contributed to and are pledged for the ExGen Renewables IV non-recourse debt project financing structure. Refer
to Note 16 — Debt and Credit Agreements for additional information on ExGen Renewables IV.

As of December 31, 2019 and 2018, 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 Transition 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.

ACE’s equity investment is a variable interest
as, by design, it absorbs any initial variability
of ACETF. The bondholders also have a
variable interest for the investment made to
purchase the transition bonds.

ACE controls the servicing activities.

Unconsolidated VIEs

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, 2019 and 2018, 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.

Note 22 — Variable Interest Entities

For each of the unconsolidated VIEs, Exelon and Generation have assessed the risk of a loss equal to their maximum exposure to be remote and, accordingly,
Exelon and Generation have not recognized a liability associated with any portion of the maximum exposure to loss.

As of December 31, 2019 and 2018, Exelon's and Generation's unconsolidated VIEs consist of:

Unconsolidated VIE groups:

Reason entity is a VIE:

Reason Generation is not the primary beneficiary:

Equity investments in distributed energy companies -

1) Generation has a 90% equity ownership in a distributed energy company.
2) Generation, via a consolidated VIE, has a 90% equity ownership in a
distributed energy company (See Consolidated VIEs disclosure above).

Generation fully impaired this investment in the third quarter of 2019. See
note 11- Asset Impairments for additional information.

Similar structures to a limited partnership and
the limited partners do not have kick out rights
with respect to the general partner.

Generation does not conduct the operational
activities.

Energy Purchase and Sale agreements - Generation has several energy
purchase and sale agreements with generating facilities.

PPA contracts that absorb variability through
fixed pricing.

Generation does not conduct the operational
activities.

Note 24 — Related Party Transactions

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 9 — Asset Retirement Obligations for additional information.

The following table presents noncurrent receivables from affiliates at ComEd and PECO which are recorded as noncurrent payables to affiliates at Generation:

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.

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  2019,  each  registrant’s  management,  including  its  principal  executive  officer  and  principal  financial  officer,  evaluated  the
effectiveness  of  that  registrant’s  disclosure  controls  and  procedures  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, 2019, 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 2019 that have materially affected, or are reasonably likely to materially affect, any of the registrant's internal control over financial reporting.

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, 2019. As a result of that
assessment,  management  determined  that  there  were  no  material  weaknesses  as  of  December  31,  2019 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.

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  ranging  from  0%  to  150%  of  target  award  values  and  to  a  total  shareholder  return  modifier.  For  performance
shares granted in 2017, 2018 and 2019, the total includes the number of shares that could be issued pursuant to the terms of the Exelon LTIP plan, which provides that
final payouts are made 50% in shares of stock and 50% in cash, and if the performance and total shareholder return modifier metrics were both at maximum, representing
a best case performance scenario, for a total of 4,005,200 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 2,002,600. The deferred stock units granted to directors includes  467,218 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 occurs after a director terminates service to the Exelon
board or the board of any of its subsidiary companies. See Note 20 — Stock-Based Compensation Plans of the Combined Notes to Consolidated Financial Statements for

DESCRIPTION OF SECURITIES

As of December 31, 2019, the common stock of Exelon Corporation (“Exelon” or the “Company”) is registered under Section 12(b)
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The summary of the general terms and provisions of the Company’s common stock set forth below does not purport to be complete
and is subject to and qualified by reference to the Company’s Articles of Incorporation (as amended, the “Articles”) and Bylaws (as
amended, the “Bylaws,” and together with the Articles, the “Charter Documents”), each of which is incorporated by reference as an
exhibit to the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission of which this Exhibit is a
part. For additional information, please read the Company’s Charter Documents and the applicable provisions of the Pennsylvania
Business Corporation Law of 1988 (as amended from time to time, the “PBCL”).

Description of Capital Stock

Authorized  Capital  Stock.  The  Company  is  authorized  under  the  Articles  to  issue  2,100,000,000  shares,  divided  into
2,000,000,000  shares of  common stock,  without  par  value,  and 100,000,000  shares of  preferred stock,  without par  value. As  of
December  31,  2019,  the  Company  had  976,152,022  shares  of  common  stock  outstanding,  and  zero  shares  of  preferred  stock
outstanding. The outstanding shares of the Company’s common stock are fully paid and nonassessable.

Voting Rights. Except as otherwise provided in the Charter Documents or by law, the holders of common stock have the exclusive
voting power, and every holder of common stock is entitled to one vote for every share of common stock standing in the name of
the shareholder on the Company’s books. Except as otherwise provided in the PBCL or the Charter Documents, whenever any
corporate action is to be taken by vote of the shareholders of the Company, it shall be authorized by a majority of the votes cast at
a duly organized meeting of shareholders by the holders of shares entitled to vote thereon. The shareholders of the Company may
act only at a duly organized meeting. The Board of Directors of the Company shall have the full authority permitted by law to
determine the voting rights, if any, and designations, preferences, limitations, and special rights of any class or any series of any
class of preferred stock that may be desired to the extent not determined by the Charter Documents.

Dividend Rights. Holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from
time to time by the Board of Directors, in its discretion, out of funds legally available therefor, subject to any preferential dividend
rights of outstanding preferred stock.

Liquidation Rights. In the event of a liquidation, dissolution or winding up of the Company, the holders of the Company’s

common stock are entitled to share ratably in all assets remaining

after the payment of all of the Company’s liabilities and subject to the liquidation preferences of any outstanding preferred stock.

Other Rights and Preferences. The Company’s common stock does not carry preemptive rights, is not redeemable, does not
have  any  conversion  rights,  is  not  subject  to  further  calls  and  is  not  subject  to  any  sinking  fund  provisions.  The  rights  and
preferences of holders of the Company’s common stock are subject to the rights of any series of preferred stock that the Company
may issue.

Listing. The Company’s common stock is listed on The Nasdaq Stock Market LLC under the trading symbol “EXC”.

Certain Anti-Takeover Provisions

Potential  Issuances  of  the  Company’s  Preferred  Stock.  Although  the  Company  does  not  currently  have  any  shares  of
preferred  stock  outstanding,  it  is  authorized  under  the  Articles  to  issue  100,000,000  shares  of  preferred  stock,  and  the  rights,
preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders
of any series of preferred stock that the Company may designate and issue in the future. The Articles also authorize the Company’s
Board of Directors to establish, from the authorized but unissued shares, one or more series of the shares of preferred stock and to
determine, with respect to any such series of the Company’s preferred shares, the terms and rights of such series, including, for
example,  the  designation,  the  number  of  shares,  the  dividend  rate  of  the  shares,  the  right,  if  any,  of  the  Company  to  redeem
shares,  the  voting  power,  if  any,  the  obligation,  if  any,  of  the  Company  to  retire  shares,  the  terms  and  conditions,  if  any,  upon
which  shares  shall  be  convertible  into  or  exchangeable  for  shares  of  stock  of  any  other  class  or  classes,  and  any  other  rights,
preferences or limitations of the shares of such series.

The authorized shares of the Company, including shares of preferred stock and common stock, will be available for issuance
without further action by the Company’s shareholders, unless such action is required by applicable law or the rules of any stock
exchange or automated quotation system on which the Company’s securities may be listed or traded.

Provisions for Shareholder Nominations and Shareholder Proposals at Annual Meetings. The Company’s Bylaws establish an
advance  notice  procedure  for  shareholders  to  nominate  candidates  for  election  as  directors  or  to  bring  other  business  before
annual meetings of the Company’s shareholders (the “Shareholder Notice Procedure”). The Shareholder Notice Procedure requires
that written notice of nominations or proposals for substantive business must be received by the Company not less than 120 days
nor  more  than  150  days  prior  to  the  first  anniversary  of  the  date  on  which  the  Company  first  mailed  its  proxy  materials  to
shareholders  for  the  prior  year’s  annual  meeting  of  shareholders;  provided,  that  nothing  in  the  Bylaws  affects  any  rights  of
shareholders to request inclusion of proposals in the Company’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

A  shareholder  who  wishes  to  recommend  a  candidate  (including  a  self-nomination)  to  be  considered  by  the  Corporate
Governance Committee of the Board for nomination as a Director must submit the recommendation in writing to the Chair of the
Corporate  Governance  Committee  as  set  forth  in  the  Bylaws.  The  Corporate  Governance  Committee  will  consider  all
recommended candidates and self-nominees when making its recommendation to the full Board of Directors to nominate a slate
of Directors for election. A shareholder may also use one of two alternative provisions of the Bylaws to nominate a candidate for
election  as  a  Director.  Under  one  provision  of  the  Bylaws  currently  in  effect,  a  shareholder  must  comply  with  the  Shareholder
Notice  Procedure  and  the  notice  must  include  information  set  forth  in  the  Bylaws.  Under  this  procedure,  any  shareholder  can
nominate any number of candidates for Director for election at the annual meeting, but the shareholder’s nominees will not be
included in Exelon’s proxy statement or form of proxy for the meeting.

In addition, A shareholder who meets criteria in the Exelon bylaws may also nominate a limited number of candidates for
election  as  Directors  through  provisions  commonly  referred  to  as  “proxy  access.”  Subject  to  the  requirements  set  forth  in  the
Bylaws, any shareholder or group of up to 20 shareholders holding both investment and voting rights with respect to at least 3% of
Exelon’s  outstanding  common  stock  continuously  for  at  least  3  years  may  nominate  up  to  20%  of  the  Exelon  Directors  to  be
elected.  The  nominating  shareholder(s)  must  comply  with  the  Shareholder  Notice  Procedure  and  the  notice  must  include
information  required  under  the  Bylaws.  Under  this  procedure,  the  shareholder’s  nominees  will  be  included  in  the  Exelon  proxy
statement and the form of proxy for the meeting.

Provisions  Relating  to  the  Election  of  the  Company’s  Board  of  Directors.  Under  the  Articles  Articles,  shareholders  are
entitled  to  only  one  vote  for  each  share  held  in  all  elections  for  directors.  Directors  are  elected  by  a  plurality  of  votes  cast.  In
addition, each director must meet the suitability requirements set forth in the Bylaws.

Removal of Company Directors. Under the Bylaws, the entire Board of Directors or any individual Director may be removed
from office by vote of the shareholders entitled to vote thereon only for cause. In case the Board or any one or more Directors are
so removed, new Directors may be elected at the same meeting.

Director Vacancies. Under the Bylaws, vacancies in the Board of Directors, including vacancies resulting from an increase in
the number of Directors, may be filled by a majority vote of the remaining members of the Board though less than a quorum, or by
a sole remaining director, and each person so selected shall be a Director to serve until the next annual meeting of shareholders,
and until a successor has been selected and qualified or until his or her earlier death, resignation or removal.

Amendment to Articles. Any amendment to the articles requires the affirmative vote of a majority of the votes cast by all
shareholders entitled to vote thereon and, if any class or series of shares is entitled to vote thereon as a class, the affirmative vote
of a majority of the votes cast in each such class vote, except for amendments on matters specified in Section 1914(c) of the PBCL
that do not require shareholder approval.

Amendment to Bylaws. Except as otherwise provided for in the express terms of any series of the shares of the Company,
any one or more provisions of the Bylaws may be altered or repealed by the Board of Directors. The shareholders or the Board of
Directors may adopt new, except that the Board of Directors may not adopt, alter or repeal bylaws that the PBCL specifies may be
adopted  only  by  shareholders,  and  the  Board  of  Directors  may  not  alter  or  repeal  any  bylaw  adopted  by  the  shareholders  that
presumes that such bylaw shall not be altered or repealed by the Board of Directors.

Special Meeting of Company Shareholders. The Charter Documents do not contain a provision permitting shareholders to

call a special meeting.

Shareholder  Action  by  Written  Consent.  The  Charter  Documents  do  not  contain  a  provision  permitting  action  by  written

consent of the shareholders.

Pennsylvania  Anti-Takeover  Statutes.  Under  Section  1715  of  the  PBCL,  directors  stand  in  a  fiduciary  relation  to  their
corporation and, as such, are required to perform their duties in good faith, in a manner they reasonably believe to be in the best
interests of the corporation and with such care, including reasonable inquiry, skill and diligence, as a person of ordinary prudence
would  use  under  similar  circumstances.  In  discharging  their  duties,  directors  may,  in  considering  the  best  interests  of  their
corporation,  consider  various  constituencies,  including,  shareholders,  employees,  suppliers,  customers  and  creditors  of  the
corporation, and upon communities in which offices or other establishments of the corporation are located. Absent a breach of
fiduciary duty, a lack of good faith or self-dealing, any act of the Board of Directors, a committee thereof or an individual director is
presumed to be in the best interests of the corporation. The PBCL expressly provides that the fiduciary duty of directors does not
require them to (i) redeem or otherwise render inapplicable outstanding rights issued under any shareholder rights plan; (ii) render
inapplicable the anti-takeover statutes set forth in Chapter 25 of the PBCL (described below); or (iii) take any action solely because
of the effect it may have on a proposed acquisition or the consideration to be received by shareholders in such a transaction.

Chapter  25  of  the  PBCL  contains  several  anti-takeover  statutes  applicable  to  publicly-traded  corporations.  Corporations

may opt-out of such anti-takeover statutes under certain circumstances. The Company has not opted-out of any of such statutes.

Section 2538 of Subchapter 25D of the PBCL requires certain transactions with an “interested shareholder” to be approved
by a majority of disinterested shareholders. “Interested shareholder” is defined broadly to include any shareholder who is a party
to the transaction or who is treated differently than other shareholders and affiliates of the corporation.

Subchapter  25E  of the  PBCL  requires  a  person  or  group  of  persons  acting  in  concert  which  acquires  20%  or  more  of  the
voting shares of the corporation to offer to purchase the shares of any other shareholder at “fair value.” “Fair value” means the
value  not  less  than  the  highest  price  paid  by  the  controlling  person  or  group  during  the  90-day  period  prior  to  the  control
transaction, plus a control premium. Among other exceptions, Subchapter 25E does not apply to shares acquired directly from the
corporation in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended, or to a one-step
merger.

Subchapter  25F  of  the  PBCL  generally  establishes  a  5-year  moratorium  on  a  “business  combination”  with  an  “interested
shareholder.” “Interested shareholder” is defined generally to be any beneficial owner of 20% or more of the corporation's voting
stock.  “Business  combination”  is  defined  broadly  to  include  mergers,  consolidations,  asset  sales  and  certain  self-dealing
transactions. Certain restrictions apply to business combination following the 5-year period. Among other exceptions, Subchapter
25F will be rendered inapplicable if the board of directors approves the proposed business combination or approves the interested
shareholder's acquisition of 20% of the voting shares, in either case prior to the date on which the shareholder first becomes an
interested shareholder.

Subchapter  25G  of  the  PBCL  provides  that  “control  shares”  lose  voting  rights  unless  such  rights  are  restored  by  the
affirmative vote of a majority of (i) the disinterested shares (generally, shares held by persons other than the acquirer, executive
officers of the corporation and certain employee stock plans) and (ii) the outstanding voting shares of the corporation. “Control
shares” are defined as shares which, upon acquisition, will result in a person or group acquiring for the first time voting control
over (a) 20%, (b) 331/3% or (c) 50% or more of the outstanding shares, together with shares acquired within 180 days of attaining
the applicable threshold and shares purchased with the intention of attaining such threshold. A corporation may redeem control
shares  if  the  acquiring  person  does  not  request  restoration  of  voting  rights  as  permitted  by  Subchapter  25G.  Among  other
exceptions,  Subchapter  25G  does  not  apply  to  a  merger,  consolidation  or  a  share  exchange  if  the  corporation  is  a  party  to  the
transaction agreement.

Subchapter 25H of the PBCL provides in certain circumstances for the recovery by the corporation of profits realized from
the  sale  of  its  stock  by  a  controlling  person  or  group  if  the  sale  occurs  within  18  months  after  the  controlling  person  or  group
became a controlling person or group, and the stock was acquired during such 18-month period or within 24 months before such
period. A controlling person or group is a person or group that has acquired, offered to acquire, or publicly disclosed an intention
to  acquire  20%  or  more  of  the  voting  shares  of  the  corporation.  Among  other  exceptions,  Subchapter  25H  does  not  apply  to
transactions approved by both the board of directors and the shareholders prior to the acquisition or distribution, as appropriate.

Subchapter  25I  of  the  PBCL  mandates  severance  compensation  for  eligible  employees  who  are  terminated  within  24
months after the approval of a control share acquisition. Eligible employees generally are all employees employed in Pennsylvania
for at least two years prior to the control share approval. Severance equals the weekly compensation of the employee multiplied
by the employee's years of service (up to 26 years), less payments made due to the termination.

Subchapter 25J of the PBCL requires the continuation of certain labor contracts relating to business operations owned at

the time of a control share approval.

PECO ENERGY COMPANY
DESCRIPTION OF SECURITIES

As of December 31, 2019, PECO Energy Capital Trust III (the Trust), a statutory business trust and indirect, wholly owned subsidiary
of PECO Energy Company (PECO), had 78,105 Capital Trust Pass-Through Securities (the Capital Securities) registered under Section
12(b)  of  the  Securities  Exchange  Act  of  1934,  as  amended  (the  Exchange  Act).  The  Capital  Securities  each  represent  a  7.38%
Cumulative Preferred Security, Series D (a Series D Preferred Security) of PECO Energy Capital, L.P., a limited partnership formed
under  the  laws  of  the  State  of  Delaware  (PECO  Energy  Capital).  Each  share  of  the  Series  D  Preferred  Securities  has  a  stated
liquidation preference of $1,000.

The Trust used the proceeds from the sale of its Capital Securities to purchase the Series D Preferred Securities, which will be the
sole assets of the Trust.  PECO Energy Capital lent the proceeds from the sale of its Series D Preferred Securities, plus the capital
contribution made by PECO Energy Capital Corp., a Delaware corporation and the sole general partner of PECO Energy Capital, to
PECO, which loan was evidenced by PECO’s 7.38% Subordinated Deferrable Interest Debentures, Series D, due 2028 (the Series D
Subordinated Debt Securities).

Holders of the Capital Securities are entitled to receive distributions at the rate of 7.38% of the liquidation amount of $1,000 per
Capital Security accumulating from the date of original issuance and payable (subject to any extension period) semiannually in
arrears on April 30 and October 31, of each year, commencing April 30, 1998.  Whenever the Trust receives any cash distribution
representing a semiannual distribution on the Series D Preferred Securities (whether or not distributed by PECO Energy Capital on
the regular semiannual distribution date therefor) or payment under the Payment and Guarantee Agreement (the Series D
Guarantee) issued by PECO for the benefit of the holders of the Series D Preferred Securities, the Trust will distribute such
amounts to the holders of the Capital Securities in proportion to their respective number of Series D Preferred Securities
represented by such Capital Securities.

Through the Series D Guarantee, the Amended and Restated Trust Agreement relating to the Trust, the Indenture dated as of July
1, 1994 between PECO and First Union National Bank, as successor trustee, and the Series D Subordinated Debt Securities, taken
together, PECO fully, irrevocably and unconditionally guarantees all of PECO Energy Capital's obligations under the Series D
Preferred Securities.  Under the Series D Guarantee, PECO will guarantee payment of accumulated and unpaid semiannual
distributions, amounts payable upon redemption and amounts payable upon liquidation with respect to the Series D Preferred
Securities, in each case, only to the extent that PECO Energy Capital has funds on hand legally available therefor and payment does
not violate applicable law.  The obligations of PECO under the Series D Guarantee are subordinate and junior in right of payment to
all general liabilities of PECO and its obligations under the Series D Subordinated Debt Securities will be subordinate and junior in
right of payment to all senior indebtedness of PECO.

COMMONWEALTH EDISON COMPANY
DESCRIPTION OF SECURITIES

As  of  December  31,  2019,  Commonwealth  Edison  Company  (“ComEd”  or  the  “Company”)  had  two  classes  of  common  stock
purchase warrants registered under Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); the
Company’s common stock, into which both classes of warrants are exercisable, is not registered under Section 12 of the Exchange
Act.

1971 Warrants

On  April  13,  1971,  the  ComEd  Board  of  Directors  created  a  series  of  common  stock  purchase  warrants  (the  1971  Warrants),
pursuant to which holders can convert the 1971 Warrants into the Company’s common stock at a rate of one (1) share of common
stock  for  every  three  (3)  warrants;  prior  to  April  30,  1981,  the  1971  Warrants  were  exercisable  into  shares  of  the  Company’s
common stock at a rate of one (1) share of common stock for every three (3) warrants at an exercise price of $30 per warrant. The
1971 Warrants do not have an expiration date.

The 1971 Warrants have no established trading market and there is no assurance concerning the liquidity of any market that may
develop for the 1971 Warrants. Consequently, holders of the 1971 Warrants may not be able to liquidate their investment readily,
and lenders may not readily accept the 1971 Warrants as collateral for loans.

As of December 31, 2019, there were 40,588 1971 Warrants outstanding.

Series B Warrants

On February 1, 1972, the ComEd Board of Directors created a series of common stock purchase warrants (the Series B Warrants),
pursuant  to  which  holders  can  convert  the  Series  B  Warrants  into  the  Company’s  common  stock  at  a  rate  of  one  (1)  share  of
common  stock  for  every  three  (3)  warrants;  prior  to  April  30,  1981,  the  Series  B  Warrants  were  exercisable  into  shares  of  the
Company’s common stock at a rate of one (1) share of common stock for every three (3) warrants at an exercise price of $30 per
warrant. The Series B Warrants do not have an expiration date.

The Series B Warrants have no established trading market and there is no assurance concerning the liquidity of any market that
may  develop  for  the  Series  B  Warrants.  Consequently,  holders  of  the  Series  B  Warrants  may  not  be  able  to  liquidate  their
investment readily, and lenders may not readily accept the Series B Warrants as collateral for loans.

As of December 31, 2019, there were 19,670 Series B Warrants outstanding.

assumptions to be used in arriving at any calculations. For purposes of making the calculations and determinations under this
Section 5.11, the accountants may make reasonable assumptions and approximations concerning the application of Sections
280G and 4999 of the Code. The Plan Administrator shall furnish to the accountants information and documents as the

Employment, such term and similar terms shall be deemed to refer to such Participant’s “separation from

Participant in no event later than the last day of the calendar year following the calendar year in which such
Participant incurred the reimbursable expense. Any amount of expenses eligible for reimbursement, or in-kind
